However anxiety 1-10 rating scale doxepin 75 mg overnight delivery, serum copper and ceruloplasmin levels were lower and urinary copper excretion higher than normal anxiety 4 hereford doxepin 25 mg buy with amex. Early detection and treatment of asymptomatic homozygotes may prevent the necessity for subsequent liver transplantation zantac anxiety symptoms doxepin 10 mg discount. The more than 30 mutations of the gene located on chromosome 15124 account for the wide clinical variability of the disease anxiety symptoms 10 year old buy doxepin 75 mg online. In Quebec anxiety symptoms in head order doxepin 75 mg, where the disease was first described in 1967 by Larochelle et al,126 the incidence of the disease is 1 in 10,000 but rises to 1 in 800 births in one geographically isolated area. In Quebec, neonatal screening programs on dried blood spots are important for early detection in this high-risk population. Although serum tyrosine, methionine, and phenylalanine levels are elevated in serum, these elevations are not thought to mediate the toxic injury. Accumulation of fumarylacetoacetate and maleylacetoacetate most likely mediates the cellular toxicity. Liver disease in tyrosinemia can be manifested as either acute or chronic disease. Frequently infants present with a bleeding diathesis, and liver failure is diagnosed secondarily. Tyrosinemia should be considered in an infant with coagulopathy even without other clinical evidence of liver failure. In these infants the liver may be pale and enlarged with already-apparent micronodular cirrhosis, bile duct proliferation, steatosis, and pseudoacinar arrangements of hepatocytes. Although it often develops after the first year of life, it should be considered even in infants or toddlers-particularly those with unexplained rickets or Fanconi syndrome. The liver is enlarged and coarsely nodular with progression from micronodular to macronodular cirrhosis. The malignancy is multifocal within the liver and may have metastasized at the time of diagnosis. The defining features of the syndrome are the acute onset of profound weakness or paralysis, painful dysesthesias, often with hypertonic posturing, and self-mutilation. Mitchell et al reported a 42% incidence of neurological crises with an associated mortality of 70% in 48 tyrosinemic children hospitalized in Quebec. These elevated levels are due to inhibition of aminolevulinic acid dehydrase by succinylacetone, a metabolite of tyrosine degradation. Treatment of neurological crises is largely supportive, although hematin, which decreases aminolevulinic acid production, may shorten the course. The starting dose is 1 mg/kg/day, but up to 2 mg/kg/day may be required in infants. The greatest benefit was seen in children in whom the disease was diagnosed and treated before 6 months of age. Of the 10% with no clinical response, five children died and three others underwent liver transplantation. The least amount of benefit was seen in those beginning therapy after 2 years of age. This population was heterogeneous, with tyrosinemia newly diagnosed in some children and others managed for often long periods by dietary restriction alone. It is important to avoid tyrosine levels greater than 500 mol/L, which are associated with corneal lesions, hyperkeratotic lesions of the palms and soles, and potentially nervous system abnormalities. In 1985 Starzl et al145 reported the successful outcome of four children with chronic tyrosinemia and made the important point that transplantation should be considered early, before hepatoma develops. All 5 children were younger than 2 years at transplantation, and in 3, both lobes were involved. The diagnosis of hepatoma itself is fraught with difficulties because serum -fetoprotein levels cannot generally be used as a marker. Similarly, computed tomographic scans and ultrasonograms may show liver nodules, even very early in the course of the disease, that may not be malignant. Unfortunately, maintenance of normal tyrosine levels by dietary means is no protection against the development of hepatoma or the progression of liver disease. As experience has accrued with liver transplantation in small infants, the fear of a poor outcome in such young recipients has been allayed. Esquivel et al147 reported an 80% survival rate in infants younger than 1 year who underwent transplantation for tyrosinemia. Although many of the clinical features of tyrosinemia resolve,155,156 liver transplantation does not guarantee complete reversal of the kidney impairment seen in hereditary tyrosinemia. The ongoing endogenous production of succinylacetone is the most likely explanation, but heterogeneity in local expression of tyrosinemia in the kidney is evident by the variation in kidney function reported after liver transplantation. Urea Cycle Defects Biosynthesis of urea is dependent on six enzymes, all of which are localized in the liver. Exchange transfusion, peritoneal dialysis, and hemodialysis can acutely lower ammonia concentrations but are impractical for long-term management. Sodium benzoate, either orally or intravenously, also lowers ammonia levels by allowing the excretion of nitrogen as hippurate. Long-term risks include protein deficiency, growth retardation, accidental overdose of drugs used to lower ammonia levels, and the unpredictable recurrence of coma leading to devastating neurological injury. The overall survival rate was 84%, but 56% sustained neurological impairment following such episodes. Liver transplantation, either complete or auxiliary, could be predicted to cure urea cycle defects with normalization of ammonia levels reported with 24 hours of transplantation. The barrier to liver transplantation in the very young is being lowered as the technique of and expertise in transplantation have become perfected, as demonstrated by successful liver transplantation in a 14-day-old for a urea cycle defect. The viability of allogeneic hepatocytes, despite immunosuppression, remains the hurdle to overcome for this modality to be successful in the long term. The diagnosis is suggested by markedly elevated serum ammonia levels, low or normal blood urea, low serum citrulline levels, and severe oroticaciduria. Liver biopsy is not necessary for diagnosis and in fact has been associated with precipitating hyperammonemic crises and subsequent death. Heterozygote girls may show a spectrum of clinical disease consistent with the Lyon hypothesis of random inactivation of the normal X chromosome. Generally the younger the child at transplantation, the better the neurological prognosis. Four of these boys have mild to moderate neurological impairments that seem to correlate with pretransplant cognitive function and became more noticeable as they approached school age. Normalization of serum ammonia levels on a full diet without any medications was achieved. This case exemplifies the principle that only a portion of a normal liver is required to provide enough normal enzyme activity to reverse the metabolic deficit. There are a handful of reports of liver transplantation in children with carbamoyl-phosphate synthetase deficiency. A 14-day-old boy successfully underwent transplantation with a newborn deceased donor liver and has had complete normalization of serum ammonia levels on an unrestricted diet. He has some delay in developmental milestones, which the authors attribute to a brain abscess after transplantation. Although his serum ammonia levels normalized, citrulline levels remained undetectable and dietary supplementation was needed. A severe neonatal form has been described, with some survivors beyond the neonatal period161 who were successfully transplanted. In one, plasma citrulline levels remained high,189 and in the other they normalized. However, despite good dietary compliance, these children may suffer life-threatening crises. Although the enzymatic defects are not confined to the liver, several children have undergone liver transplantation with variable success. Methylmalonicacidemia and Propionicacidemia Of the organic acidemias, liver transplantation for methylmalonicacidemia is the most commonly reported with over 30 cases of liver and combined liver-kidney transplantation, reported in the medical literature. A significant number of patients with methylmalonicacidemia have been reported to have renal insufficiency at the time of transplant. Indeed end-stage kidney disease develops in longterm survivors, which should prompt evaluation for combined liver-kidney transplantation by the medical teams involved with these patients. Despite medical management with dietary protein restriction and carnitine supplementation, disease exacerbations with vomiting, dehydration, acidosis, and hypoglycemia may occur and be manifested as acute emergencies. At this time liver transplantation appears to have a dubious role in providing long-term benefit to most of these patients. The defective enzyme in patients with propionicacidemia, propionyl coenzyme A carboxylase, is expressed in the liver as well as other tissues not corrected by liver transplantation. Cardiomyopathy is a well-described late complication of propionicacidemia occurring in up to one third of children in the first decade of life. Recent reports suggest that cardiomyopathy may be reversible by liver transplantation. Maple Syrup Urine Disease Maple syrup urine disease is an autosomal recessive disorder of branched-chain amino acid metabolism. Impaired activity of the branched-chain 2-oxoacid dehydrogenase complex results in the accumulation of branched chain l-amino acids (leucine, isoleucine, and valine) and 2-oxoacids. Children often present in infancy with obtundation, coma, and seizures, with some succumbing to cerebral edema. Neurological sequelae can be averted by aggressive medical management during crises, including growth hormone and insulin infusions, hemofiltration or dialysis, and rigorous management of cerebral edema. With very strict control of dietary protein, which requires gastrostomy tube feeding in infants, further neurological crises can be avoided in some children. However, crises can occur even with full compliance with the proteinrestricted diet and can be precipitated by any catabolic stress, such as an intercurrent illness, exercise, fasting, or dehydration. The risk for sustaining neurological damage from such episodes continues throughout life. Liver transplantation should be considered in children without significant neurological damage who have already proved difficult to control with dietary protein restriction alone. Galactosemia is caused by a deficiency in galactose 1-phosphate uridyltransferase. Galactosemia occurs in the first few days after milk feeding begins and produces a life-threatening illness with vomiting, jaundice, hepatomegaly, liver failure, and kidney-type Fanconi syndrome. Acute decompensations in the neonatal period frequently are associated with Escherichia coli bacteremia. Infants are acidotic, and galactose, a reducing substance, can be demonstrated in the urine. Most infants in the United States are identified with newborn screening,208 and elimination of all milk products from the diet reverses the acute liver and kidney decompensation, and emergency liver transplantation is not necessary. The enzymatic defect also occurs in many other extrahepatic sites such as red blood cells, skin fibroblasts, and intestinal mucosal cells. Hereditary fructosemia (fructose 1-phosphate aldolase deficiency) is recognized in the first few months of life after the introduction of fruit sugars and sucrose to the diet. The clinical features are quite similar to those of galactosemia and consist of failure to thrive, vomiting, fulminant liver failure, and Fanconi syndrome. The infants are characteristically hypoglycemic with hypophosphatemia and lactic acidosis. However, with the elimination of fructose, sucrose, and sorbitol from the diet, complete recovery occurs and liver transplantation is not necessary. The gene is located on chromosome 3p14, and several mutations have been described, thus accounting for the variability in clinical findings. In such patients, dietary management is not successful, and death from cirrhotic liver disease occurs within the first few years of life unless liver transplantation is performed. However, because the enzymatic defect is not limited to hepatocytes, ongoing accumulation in extrahepatic tissue can occur. No evidence was found of progressive amylopectin accumulation in extrahepatic sites, and a reduction in cardiac amylopectin was described in one child. These authors postulated that microchimerism, in which enzymatically normal cells migrate from the graft to the periphery, may be the mechanism by which the diffuse cellular enzymatic defect can be ameliorated. Hepatomegaly, hypoglycemia, lactic acidosis, and growth failure occur in infancy but can generally be well controlled by frequent glucose and starch feeding and avoidance of lactose and sucrose. Hyperuricemia may lead to kidney stone formation and requires allopurinol treatment. For such life-threatening complications, liver transplantation has been successfully performed with complete resolution of the metabolic defect, good catch-up growth, and improved quality of life. Malignant transformation of these adenomas has been described and is an indication for liver replacement. This complication generally occurs in postpubertal patients, with an incidence varying between 22% and 75% and an estimated risk that 10% will undergo malignant transformation. Because the adenomas are usually multiple, surgical resection does not typically provide definitive treatment. As children with glucose-6-phosphatase deficiency survive longer, they should be regularly screened for the development of adenomas, with subsequent biopsy of discovered adenomas. If either dysplasia or malignant change is found, liver transplantation should be considered. Two billion hepatocytes in two separate infusions were given through an indwelling portal vein catheter, and triple-drug immunosuppression was administered. Subsequent reports of hepatocyte transplantation for glycogen storage disease have appeared in the literature with a transient improvement in metabolic function. Disease in such patients is also refractory to treatment with drugs that lower plasma cholesterol levels because both bile-sequestrating agents and the 3-hydroxy3-methylglutaryl coenzyme A reductase inhibitors. Other reports quickly followed of isolated liver transplantation with coronary bypass,233 sequential heart and liver transplantation,234 or combined liver-heart transplantation.

Dietary cholesterol, rather than liver steatosis, leads to hepatic inflammation in hyperlipidemic mouse models of nonalcoholic steatohepatitis. These conditions are rarely seen at any given transplant center and, as a result, may not be recognized as an indication for liver transplantation. This chapter identifies 256 specific reasons for liver transplantation in various unusual conditions for which liver transplantation has been shown to be effective therapy. As a result of this deficiency, overproduction of oxalate from glycine occurs in the liver and leads to progressive calcium oxalate formation, nephrocalcinosis, and eventually 23 UnUsUal IndIcatIons for transplantatIon 257 renal failure. Hyperdialysis and medical therapy should be used in these patients to reduce serum oxalate levels before and after combined kidney and liver transplantation. Ideally these measures should be initiated before kidney and liver transplantation. Nonetheless, urine oxalate levels remain markedly elevated for many months or even years after successful liver transplantation. Therefore there is only a narrow window in which isolated liver transplant may performed. Within the first 4 weeks, all the domino recipients developed dialysisdependent kidney failure despite good liver function. In the past, end-to-side portocaval shunting and ileal bypass were used to treat this condition in an effort to delay liver transplantation. Simultaneous transplantation is preferred if the heart graft functions immediately. In cases in which such is not the case, sequential transplantation can be accomplished. In most cases after liver transplantation, the serum cholesterol level declines markedly and in some cases can actually normalize. Recipients developed hypercholesterolemia after liver transplant, but it was able to be controlled with diet and medication. However, most patients have severely reduced ferrochelatase levels, thus suggesting the presence of two rather than one abnormal gene. Regardless of the specific method of inheritance, affected patients have a unique form of immediate hypersensitivity to sun exposure characterized by a burning or stinging sensation coupled with erythema and edema. Photo-excitation of protoporphyrin in the skin leads to the painful photosensitivity characteristic of the disease. Increased biliary protoporphyrin excretion exerts toxic effects on hepatobiliary structure and function, although advanced, progressive liver disease manifests in only a small minority. Once hepatic decompensation occurs, the disease progresses rapidly to death unless hepatic transplantation is accomplished. Hepatic accumulation of protoporphyrin can be reduced but not eliminated by the administration of oral charcoal, cholestyramine, or colestipol. Additional measures that have been used include frequent red blood cell transfusions to suppress erythropoiesis, administration of hematin to suppress porphyrin synthesis, and plasmapheresis to remove free protoporphyrin in plasma. Liver transplantation is the only treatment with a long-lasting effect for patients with protoporphyria that have advanced liver disease. When liver transplantation is used as a lifesaving procedure in individuals with protoporphyria, the patient needs to be prepared for surgery with aggressive plasmapheresis to remove protoporphyrin from the blood, and the operating room must be modified to reduce light exposure to exposed tissues during the transplant procedure by using red lights, which do not activate the protoporphyrin in light-exposed tissues. Biliary complications after liver transplant are more common in this group of patients. The disease is fatal with an expected survival of 12 to 15 years after the onset of clinical disease. The initial symptom is usually a peripheral neuropathy, although autonomic neuropathy with gastrointestinal and cardiovascular symptoms is also common. The presence of clinical autonomic neuropathy has a negative impact on both morbidity and mortality before and after liver transplantation. Initially liver transplantation was performed in patients who were severely malnourished and those who had advanced peripheral or autonomic neuropathy. Because the disease resolves very slowly, if at all, as the deposited amyloid material is resolubilized and removed, these patients continue to experience their disease manifestations after transplantation. Thus the results are poor, and some recipients actually die of posttransplant malnutrition, sepsis (usually urosepsis), or cardiac arrhythmias as a consequence of their persistent amyloid-induced disease processes. The current approach to patients with is to perform transplantation early after the initial onset of clinical manifestations of familial amyloid polyneuropathy their disease. The period before the onset of clinical disease is usually long, between 10 and 50 years depending on variations in phenotypic expression of amyloid polyneuropathy in different endemic areas, so acceptance of a liver from a donor with familial amyloid polyneuropathy can be expected to provide the recipient of the domino liver with 10- to 50-year disease-free (polyneuropathy) posttransplant survival. For most transplant recipients in their mid-40s or 50s, this extra risk represents a minimal addition to the inherent risks of liver transplantation. Protoporphyrininduced liver disease recurs in the transplanted liver despite the reduction in hepatic protoporphyrin production as a result of the liver transplant. Persistent production of excess protoporphyrin by bone marrow results in recurrent photosensitivity and hepatic disease. This fact strongly supports sequential transplantation of the liver followed by a bone marrow transplant in patients with protoporphyria once early clinical hepatic involvement becomes manifest. Deficits in Fatty Acid Metabolism Disorders of Fatty Acid Oxidation Advances in our understanding of the structure and function of mitochondria have led to the recognition that inherited and acquired mitochondrial dysfunction may be responsible for diseases affecting the liver and other organ systems. Mitochondrial health may also determine hepatocyte survival in other hepatic disorders not directly related to the mitochondrion. Primary mitochondrial hepatopathies are conditions in which there are inherited defects in structure or function of the mitochondria, most of which involve the respiratory chain and oxidative phosphorylation, fatty acid oxidation, the urea cycle, and other pathways confined to mitochondria. Two forms of liver disease associated with mitochondrial respiratory chain disorders have been described on the basis of clinical course and severity: a severe neonatal form with onset in the first week of life with transient hypoglycemia, neurological involvement (severe hypotonia, myoclonus epilepsy, psychomotor retardation), early liver failure, and a rapidly fatal course; and a delayed form with onset after age 2 months, with hepatic failure occurring later in the course of the disease. These diseases can occur in the first few months of life and are characterized by lactic acidosis, jaundice, conjugated hyperbilirubinemia, abnormal serum alanine aminotransferase levels, coagulopathy, ketotic hypoglycemia, and hyperammonemia. Liver biopsy specimens from affected patients show microvesicular steatosis, canalicular cholestasis, and bile duct proliferation. The periportal and centrilobular fibrosis in these cases can progress to overt micronodular cirrhosis. Glycogen depletion and iron deposition within the liver are common in these disease processes. Once initiated, the disease process is rapidly progressive and leads to death from liver failure or sepsis, or from both. Most patients have severe neurological involvement with weakness, hypotonia, poor cry and suck responses, recurrent episodes of apnea, and myoclonic seizures. Patients with neurological signs and symptoms are not candidates for liver transplantation because these findings do not revert but can continue and lead to severe neurological disease and death. Some patients, however, do not have neurological findings, and these few can undergo successful liver transplantation. This disorder is manifested within the first week of life as hypotonia, hepatic failure, renal dysfunction, and lactic acidosis. In a few cases the disease appears to be liver specific and spares the muscle, brain, kidneys, and heart. This acquired form of hepatic mitochondrial disease is due to an interaction between a viral illness (influenza, varicella, enteroviruses, and other viruses) and salicylate therapy and results in defective ureagenesis, ketogenesis, hyperammonemia, hypoglycemia, elevated free fatty acid levels, lactic acidosis, and the production of various dicarboxylic acids. Most cases occur in the autumn and winter, when viral illnesses in children ages 5 to 15 years are most frequent. After several hours of vomiting, which can be severe and lead to dehydration, encephalopathy develops. Serum alanine and aspartate aminotransferase levels increase, as does the blood ammonia level. Mild to moderate prolongation of the prothrombin time and hypoglycemia also occur. It is important to note that despite the potentially lethal disease, the serum bilirubin level remains normal. Liver biopsy samples show microvesicular steatosis in the absence of hepatic inflammation or necrosis. In these latter cases, liver transplantation is indicated as a lifesaving procedure. These disorders are associated with variable degrees of hepatic steatosis, hyperammonemia, an elevated lactateto-pyruvate ratio, lactic acidosis, ketosis, and hepatic disease that occurs suddenly and progresses rapidly to coma and death in the absence of hyperbilirubinemia. In these more advanced cases, liver transplantation is lifesaving and may have to be performed either before or after delivery. Other defects in fatty acid oxidation that can occur rarely and cause liver failure in pregnant women include trifunctional protein deficiency, carnitine palmitoyltransferase deficiency, and short-chain acyl-CoA dehydrogenase deficiency. Cystic Fibrosis Cystic fibrosis is an autosomal recessive multisystem disease, primarily affecting the lungs, pancreas, gastrointestinal tract, and liver. Focal biliary cirrhosis can progress to multilobular cirrhosis with clinically significant portal hypertension and related complications. Preferably, patients should undergo isolated liver transplantation before their lung function declines to a critical stage because combined liver-lung transplantation carries a worse prognosis. The overall survival rates after sole liver transplantation in adults and children were 85% and 90% at 1 year and 65% and 85% at 5 years, respectively. No single mutation in any of these disorders has been shown to define the disease. Rather, a large number of different mutations have been identified for each disorder. Thus the diagnosis of a urea cycle defect relies on enzymatic assays of blood and urine for the metabolites that characterize each disorder. Patients present with hyperammonemia either shortly after birth (approximately 50%) or later at any age, leading to death or to severe neurological handicap in many survivors. Despite the existence of effective therapy with alternative pathway therapy and liver transplantation, outcomes remain poor. This may be related to underrecognition and delayed diagnosis due to the nonspecific clinical presentation and insufficient awareness of health care professionals because of disease rarity. Episodes of hyperammonemia no longer occur, dietary restriction is no longer necessary, and alternative pathway medications can be discontinued. It is important to note that liver transplantation does not correct the low levels of plasma arginine and citrulline present in individuals with carbamoyl phosphate synthetase deficiency or ornithine transcarbamylase deficiency because most of the citrulline in plasma is a product of intestinal rather than hepatic synthesis. Thus individuals with either of these two disorders, even after successful liver transplantation, continue to require supplements of either citrulline or arginine. Because the preexisting neurological damage appears not to reverse,56,57 it is essential to prevent endogenous catabolism and hyperammonemia before and during liver transplantation. Liver transplantation offers severely affected patients with urea cycle disorders a better alternative in terms of quality of life than medical treatment. Often the use of oral contraceptives, estrogen replacement therapy, or pregnancy is responsible for precipitating the venous thrombosis in such cases. Yet another cause of BuddChiari syndrome is the presence of a myeloproliferative disorder (usually with a mutation in the Janus tyrosine kinase-2) such as polycythemia rubra vera, essential thrombocytosis, or paroxysmal nocturnal hemoglobinuria.

However anxiety nursing interventions discount 75 mg doxepin with mastercard, endometrial malignancy should be ruled out prior to deciding the type of treatment anxiety centre generic 10 mg doxepin amex. In this case anxiety heart palpitations order generic doxepin on line, hormonal imbalance is considered the root cause of hyperplasia of the endometrium that causes menorrhagia; this often happens in anovulatory cycles with excessive or unopposed influence of oestrogen on the endometrium anxiety attack symptoms yahoo buy doxepin now. In some cases anxiety vs heart attack doxepin 75 mg generic, abnormal endometrial haemostasis is the cause of abnormal excessive bleeding. Immature development of these organs results in anovulation in the earlier years (1­5 years), unopposed oestrogen causing endometrial hyperplasia. Clinical Features Menorrhagia may be noticed from the start of menarche, but often the initial cycles may be normal. It takes the form of heavy regular cycles, or normal bleeding lasting for several days, but dysmenorrhoea is invariably absent in anovulatory cycles. It is important to rule out other causes of menorrhagia before instituting hormonal therapy. Investigations n Pathogenesis Endometrium normally produces prostaglandins from arachidonic acid, which is a fatty acid. This condition is due to several causes that make the standard methods of investigations and management inconsistent and difficult. It stands for polyp, adenomyosis, leiomyoma, malignancy, coagulopathy, ovulatory dysfunction, endometrium, iatrogenic and non classified. The first four are related to visually objective structural uterine abnormalities that can be measured visually with imaging modalities and by histopathological study. The others are non structural and attributed to coagulation disorders and hormonal dysfunction. Thereafter, oestrogen for 21 days with progestogen added for 10 days for 3­6 cycles will regularize the cycles. Androgens (danazol) are not recommended, though effective, because of androgenic effects in young girls. The drug is expensive and prolonged treatment over 4­6 months can cause osteoporosis. When the above treatments fail, uterine tamponade using Foley catheter for 24 hours can control bleeding in the acute episode. Lately, the trend is to give intravenous tranexamic acid 1 gm with 25 mg of oestrogen, and then continue with oestrogen and progesterone as mentioned above. Desmopressin analogue of arginine vasopressin is given intravenously or by nasal spray (1. Tranexamic acid inhibits tissue plasminogen activator which is a fibrinolytic enzyme, whose level increases in abnormal uterine bleeding. It is categorized and defined by ultrasound, saline sonography, hysteroscopy with or without histopathology. The category is subdivided depending upon the depth of endometrial myometrial invasion. It is important to remember that many cases of adenomyosis are asymptomatic and only diagnosed on hysterectomy specimens. Because of the number, different locations and size, this group is divided into primary, secondary and tertiary group. The primary classification reflects only the presence or absence of leiomyomas as determined by ultrasound. The diagnosis is by histopathological examination of the endometrium (D/C, biopsy) or by hysteroscopic biopsy. In rare cases, it is due to tubercular endometritis or infection, particularly chlamydial infection. There are no tests available, except for infections, to estimate the local causes, and the case is placed in this category by exclusion of other causes. The drugs that are responsible are anticoagulants, phenothiazine and tricyclic antidepressants which affect dopamine metabolism. As and when better investigations become available, they may be allocated to a new category in future. One point to be emphasized here is that D&C and endometrial study are important in premenopausal women to rule out endometrial carcinoma. Instead of D&C, uterine aspiration or hysteroscopic biopsy is chosen by some to study the endometrial lining and to detect small polypi that can be missed on ultrasound and to diagnose tubercular endometritis. This condition may simulate abortion and ectopic pregnancy if amenorrhoea precedes bleeding, but pain is conspicuously absent. Pathology A mild degree of myohyperplasia with the uterine wall measuring up to 25 mm, and a uniformly enlarged uterus is seen in metropathia haemorrhagica. Sometimes, the bleeding follows upon a normal period, while at other times, the continuous bleeding may be preceded by menorrhagia. The second feature is the absence of secretary endometrium with the absence of cock-screw glands. Areas of necrosis as seen during menstruation can be seen in the superficial surface. One or both ovaries may contain a cyst not larger than 5 cm, but corpus luteum is absent. Hysterosalpingography and saline salpingography may be employed if hysteroscopic facilities are not available. General examination, with special reference to anaemia and thyroid function, blood count, coagulation profile, is carried out. Endometrial study by curettage, uterine aspiration or hysteroscopic biopsy is mandatory in premenopausal women, and necessary in a few younger women suspected to have endometrial tuberculosis. Note that the right ovary is cystic and that the endometrium shows diffuse polyp due to hyperplasia. Oestrogen therapy alone is not recommended because of the risk of endometrial and breast cancer. Oral combined pills are effective in only select women and not safe after the age of 35 years, in smokers and obese women. A high initial dose of 10­30 mg a day should arrest bleeding in 24­48 hours, after which 5 mg daily is given for 20 days. Withdrawal bleeding occurs 2­5 days after stopping the drug, and normal blood loss is expected. A further course of 5 mg daily for 20 days is started on the second or third day of the periods cyclically for 3 to 6 months (given at night to reduce side effects). Duphaston (10 mg) does not suppress ovulation in women who desire pregnancy, and it does not influence lipoproteins. Gestrinone, a derivative of 19-nortestosterone, is effective in an oral dose of 2. Instead of a 3 week cyclical therapy, giving progestogen only in the luteal phase is not effective. Menorrhagia without any organic or general disease should be treated as follows: A wide variety of treatment modalities are now available. The treatment should be based on the age of the woman, her desire to retain fertility, previous treatment and severity of menorrhagia. If that fails, D&C may be helpful mainly for diagnostic purpose, but a few women may benefit from it therapeutically. Failing this, decision has to be taken regarding conservative surgery or hysterectomy. Instead of cyclical administration of progestogens, continuous oral progestogens daily for 3 months with a break of 1 week reduces the number of menstrual cycles to 4 in a year which many women welcome. Danazol has a limited role when oral contraceptives and progestogens are not suited to a woman. Ethamsylate reduces capillary fragility, 500 mg four times a day from 5 days prior to anticipated period, up to 10 days reduces menorrhagia by 50% Table 24. Antifibrinolytic agents-Tranexamic acid (epsilonamino-caproic acid), 1­2 g four times a day for 6­7 days during menstruation is effective in 50% of the cases. Longer duration of treatment with its anti-oestrogenic action causes menopausal symptoms and osteoporosis. It does not cause breast or uterine cancer because of its anti-oestrogenic effect. When oestrogen is not contraindicated and a woman also needs contraception, a new drug Seasonale (combined oestrogen and progestogen) is used daily for 84 days with a gap of 6 days in a three-monthly treatment. It reduces blood loss by 70­90% in 3 months, and acts as a contraceptive for those who do not desire pregnancy. However it may cause irregular bleeding during the first 3 months, and the woman is advised to persevere retaining Mirena and not get it removed on this account. Mirena is also useful in women with menorrhagia and dysmenorrhoea associated with uterine fibroid, adenomyosis. Hysterectomy is required in 25% by the end of 3 years because of recurrence of menorrhagia. Though mainly performed for diagnostic purpose, 30­40% are relieved of menorrhagia at least for a short period of time. The idea of endometrial ablation arose from oligomenorrhoea occurring in Asherman syndrome due to synechiae. These procedures are safe, effective with lesser morbidity than hysterectomy, as well as costeffective with quicker recovery. Therefore, these procedures are mainly suitable for women who wish to preserve the uterus, avoid hysterectomy, but are not interested in pregnancy. The method should destroy 2­3 mm of myometrium, if recurrence of menorrhagia has to be avoided. It is a blind procedure using radiofrequency electromagnetic thermal energy which destroys the endometrium at 66°C. First invented by Neuwirth in 1994, this instrument comprises a central computer system, battery and a disposable silicon rubber balloon catheter 5 mm in diameter. It is also useful in abnormal uterine bleeding complicated by varicose uterine vessels. The heating element in the balloon raises the temperature to 87°C (187°F) and this temperature is maintained for 8 min over a pressure of 160­180 mm Hg to exert a tamponade effect. The catheter has an inherent safety design related to time, pressure and temperature, and it gets automatically deactivated to avoid complications. About 6 mm of endometrium gets destroyed, so preoperative endometrium thinning is not required. Approximately, 70­90% resume normal cycles and 15% become amenorrhoeic by the end of 1 year. Failure in retroverted uterus is due to unequal distribution of heat over the endometrium. This system uses a single-use multi-electrode intrauterine balloon to ablate the endometrium. The silicon inflatable electrode carrier has a triangle shape which gets unfold when its insertion sheath is withdrawn. The instrument is very expensive and sufficient data is not available to assess its outcome. Goldrath advocated uterine tamponade in acute episodes of bleeding by inserting a Foley catheter, distending with 30 mL fluid and leaving the catheter for 24 h. NovaSure (impedance-controlled endometrial ablation) is the latest and most safe procedure, taking just 90 sec. In older women more than 40 years not desirous of childbearing, and who opt for hysterectomy as a primary treatment or ablation fails. Lately, many gynaecologists have shifted to vaginal hysterectomy for undescended uterus which may even be enlarged. This trend is adopted because of lesser morbidity, and lesser postoperative complications of adhesions, scar hernia and pulmonary complications. Previous surgery with possible adhesions, fixity and limitation of uterine mobility. In a woman less than 50 years, ovaries should be conserved unless they are diseased. Sequele or delayed complications of hysterectomy Although hysterectomy is a one-time procedure, safe and cures abnormal uterine bleeding, delayed complications are known to occur. Adhesions of the ovaries to the vaginal vault causing ovarian residual syndrome, dyspareunia and chronic pelvic pain. New Systems Versapoint bipolar electrosurgical system works in normal saline, is cheap, has excellent haemostasis and causes instantaneous tissue vaporization. The drawbacks are the side effects of hormones and the fact that symptoms sometimes return once the hormone therapy is stopped. Second generation ablative techniques are safer, quick to perform and are equally effective. The breakthrough bleeding occurs before the actual menstruation in the form of spotting or brownish discharge. Progestogen can suppress the bleeding, but needs to be taken on tapering dose for 20 days to complete the cycle. Adenomatous Endometrial Polyp this form of polypus is really a localized area of endometrial hyperplasia when area or areas of thickened endometrium project into the cavity of the endometrium to look like polypus. The polypus may be single or multiple, small or large enough to protrude through the cervical canal. Two per cent women with simple hyperplasia are at a risk of endometrial cancer, and 4­10% women with glandular hyperplasia develop the cancer. Atypical hyperplasia, however, has the tendency to develop into carcinoma in as much as 60­70% cases. While 80% cases of simple hyperplasia respond to progestogens, response of atypical hyperplasia is only 50%, but with the risk of malignancy. For this reason, atypical endometrial hyperplasia should be treated by hysterectomy and not merely by ablative technique. A small portion of endometrium left behind and undergoing malignancy may not be easily detected following ablative treatment.

Although increased educational programs, new legal approaches, or financial or other incentives show some promise to increase the supply of deceased donor and living donor organs, evidence from Iran suggests that such efforts will not succeed in other developing world contexts. Ways to maximize posttransplant lifeyears attempt to satisfy concerns about justice. Expanding indications for liver transplantation during this time meant increasing death rates for those on waiting lists and growing public concern about the subjective nature of the allocation process. This system improved rates of organ placement and did not reduce posttransplant survival but came with several drawbacks. Specifically, this system does not take into account all important factors, such as intolerable symptoms (pruritus) not necessarily associated with short-term risk for death, nor does it account for longterm risks in some patients, such as those with amyloidosis, familial hyperlipidemia, and portopulmonary hypertension. As a result, the system in the United States gives special priority to some patients with additional qualifying conditions, such as those just noted. These studies illustrate the practical, as well as moral, tradeoffs generated by any allocation system. Thus all approaches to allocation, even those using mathematical calculations with objective measurements of organ function, depend on the assumptions used to construct the formula. Similarly, no universally accepted moral system specifies the superiority of maximizing posttransplantation life-years versus maximizing the number of desperately ill individuals with liver failure one attempts to rescue with transplantation, recognizing many in the latter category may not survive long term. No algorithms will resolve the ethical tensions between attempting to provide individual benefit to sick patients and attempting to achieve statistical utility within the population of those with end-stage liver disease. However, transplanting the sickest patients first may also lead to poorer outcomes, greater need for retransplantation, and subsequently fewer livers for distribution. Ongoing debate will likely continue as policies related to prioritization in allocation are reviewed and refined. Although rare, intraoperative death of the liver transplant recipient before transplantation of the graft can result in an "orphan graft" that can no longer be transplanted into the intended recipient. When the intended recipient can no longer receive the living donor liver, the donor may no longer derive the benefits of helping a loved one. Geographical disparities in access to liver transplants have garnered considerable attention over the past decade. If no eligible patients are found, then livers are allocated to a patient who is not as sick within the region. A major logistical issue involves the desire to minimize cold ischemic time, thus limiting the distribution (transport) of livers nationally. Because sick patients do not live evenly distributed around the country, the waiting times vary from region to region. There has been public and professional uproar at the geographical inequities in the allocation system, prompting the Institute of Medicine in 1999 to call for "allocation [to] be based on common medical criteria and not accidents of geography. However, African Americans and Asians were transplanted at a disproportionately greater rate than their representation on the waiting list. Compared to those for whites and Hispanics/ Latinos, liver transplantation rates are increasing for African Americans and Asians. Yet Hispanics/Latinos received liver transplants at a decreasing rate between 2000 and 2008 in relation to their proportion on the waiting list. Fan et al215 observed that Asian and Hispanic/Latino liver transplant recipients had superior graft and patient outcomes across 1-, 5-, and 10-year time frames. For example, in 2010 1- and 5-year graft survival was 85% and 66%, respectively, for Asians, and 82% and 64% for Hispanics, whereas the rates were 82% and 66% for whites and 79% and 58% for African Americans. These disparities may reflect a different distribution of liver diseases across ethnic/minority groups or differential listing practices. With regard to sex, more men than women consistently received liver transplants from 2000 to 2011. Resources and the Future of Liver Transplantation For over a decade, those who treat patients with liver failure have dreamed about alternative approaches to orthotopic solid organ transplantation. Moreover, unless science can develop new sources of liver cells, those wishing to conduct trials of liver cell infusions have to compete for the substrate with surgeons using the livers for solid organ transplantation. To date, attempts to establish embryonic cell lines grown in laboratories have not succeeded, and animal liver cell sources continue to pose serious immunological and potentially problematic infection risks, even if they could produce all of the needed human proteins. Gene therapy could have the major advantage of avoiding the need for immunosuppression; however, as with hepatocyte infusions, many efforts in the field have not produced lasting clinical effects. However, the systems cannot replicate the metabolic/synthetic functions of healthy liver cells and therefore have limited utility. The devices appear to have some value, especially as a bridge to transplantation, although a significant survival benefit has not yet been demonstrated. Liver transplantation is expensive, and although the expense creates pressure to reduce costs and improve efficiency, many countervailing factors influence use of the technology. As surgical and immunosuppression techniques improve, the indications for using transplantation increase. As large programs succeed, demand for the services also increases, and the trainees and rising stars from the most successful programs spread to new or expanding programs. Although that means people may travel shorter distances to transplant centers, it also means the limited supply of organs must go to a larger number of transplant centers, reducing some of the efficiencies-and opportunities to engage in coherent research to improve outcomes-associated with high surgical volumes. In practical terms, statistical deviation from the expected patient safety performance. In the shorter term, before prevention can work, increased access to care could also improve access to subspecialty care for those with advancing chronic liver disease, which in turn might increase evaluation for transplantation and further increase the demand for livers, with an expected increase in mortality for those awaiting organs. These thorny issues require sustained and sometimes uncomfortable discussions and negotiations with patients, live donors, family members, clinical colleagues, organ procurement personnel, and policy makers, among others. Disputes about these matters can generate considerable distress, including anger, guilt, and regret. Clinicians may find it useful to avail themselves of institutional mechanisms for addressing these problems, such as ethics consultants and/or ethics committees. In each case those caught up in disagreements should try to listen carefully and see the issue from the perspective of those with different points of view. Most of the time the disputants share a desire for a peaceful resolution in which each party feels heard, respected, and in some way understood. Sometimes it helps to remember that disagreements about ethics cannot be settled by appeals to empirical science.

This chapter has touched on many of the ethical issues and decisions in the clinical arena of liver transplantation over the 30 or more years of practice. It seems likely that a better understanding of pathophysiology of neuronal death will contribute to the debate about how long after circulatory arrest one needs to wait before starting to remove solid organs. However, science will not tell us whether former patients are "dead enough" for organ retrieval following the permanent loss of cortical brain function. Similarly, neither legislation nor official policy will fully settle the problem of organ donation, complete with adequate documentation of the deceased, when surviving family members object. Nor can we use randomized controlled trials to determine (1) how many, if any, repeat transplants are justifiable; (2) whether, or how, to require that those with alcoholrelated liver disease prove that they have overcome their substance use; (3) when, if ever, developed-world Pearls and Pitfalls · Greater coverage of immunosuppressants is provided in the Affordable Care Act of 2010.

Liver biopsy assessment before termination of treatment is suggested but not essential if clinical and laboratory criteria for remission are satisfied. Liver biopsy can accurately identify histological remission and avoids premature drug withdrawal, which has a higher incidence of relapse. After remission a normal liver biopsy result has a relapse rate of 20%, compared to portal hepatitis, which has a 50% frequency of relapse at 6 months. Relapse is the recurrence of disease activity after remission and drug withdrawal, and it occurs in approximately 80% of patients who initially achieve remission. These biochemical changes are associated with interface hepatitis, and retreatment with standard medical therapy is indicated. Patients that relapse have a higher rate of esophageal varices, progression to cirrhosis, and death from hepatic failure than patients with sustained remission. One strategy is to use prednisone and titrate the dose according to symptoms and biochemical remission. The long-term use of these two strategies has not been compared head to head, but both strategies have shown inactive or minimal histological disease in 94% of follow-up liver biopsies. Twelve percent of patients treated with these schedules were able to be permanently withdrawn from medications after 70 months of follow-up. Doses are reduced after each month of clinical and biochemical improvement until conventional maintenance levels of medications are reached. Seventy-five percent of patients treated with high doses obtain clinical and laboratory remission, but only 20% achieve histological resolution. Patients who fail this regimen are at risk for liver failure and drug toxicity, and they commonly become candidates for liver transplantation and investigational protocols. Treatment extended beyond 3 years is associated with a 7% per year probability of remission and an increasing risk for drugrelated toxicity. Drug toxicity is the development of severe, drugrelated complications, which may require premature drug withdrawal or dose reduction. Corticosteroid-related intolerances are the most common causes of drug discontinuation. Cytopenia, nausea, emotional liability, hypertension, cosmetic changes, and diabetes are dose-related complications. Appropriate therapy of the complication must be included, which may include antihypertensive medication, diabetic regimens, bone maintenance schedules, gastric acid suppression, and/or antidepressants. Adjunctive Medical Treatment Adjunctive medical treatment should be implemented in patients who are on chronic corticosteroid treatment or are at high risk for developing steroid-induced complications. Postmenopausal women should consider hormonal replacement therapy, and symptomatic osteoporosis or progressive osteopenia should be treated with bisphosphonates such as alendronate (70 mg/wk). Patients should also be monitored for bone disease by annual bone mineral densitometry, and standard yearly health maintenance should also be emphasized. Alternative immunosuppressive agents have been suggested, but currently there is limited experience with their use. High risk for corticosteroid side effects include brittle diabetes, emotional instability, psychosis, osteoporosis, and uncontrolled hypertension. Acute rejection occurs in about 56% to 83% of patients and is steroid resistant in 23% to 59%. The immunosuppressive regimen should address this concern for acute allograft rejection, and any reduction in immunosuppression should be performed cautiously, particularly in the first several months following liver transplantation. Chronic rejection after liver transplantation is a cause of allograft dysfunction, leading to graft failure and retransplantation. The authors identified the following risk factors: young age of transplantation and moderate to severe acute rejection on liver biopsy, which have a higher rate of progression to chronic rejection. In fact, transplant is favored over administration of corticosteroids as initial treatment in those who present with fulminant hepatitis and liver failure, because up to 20% of patients progress despite corticosteroid use and develop potentially life-threatening complications from the immunosuppression and are at higher risk for sepsis. It seems sensible to maintainminimum effective immunosuppression, but these patients must be carefully monitored with both serological studies (serum autoantibodies and immunoglobulins) and histological examination. Recurrence in pediatric populations has been reported to be more aggressive, leading to retransplantation more often. Its diagnosis is based on the constellation of symptoms, autoantibodies, steroid dependence, increased serum transaminase levels, and hypergammaglobulinemia. Both recurrent autoimmune hepatitis and acute rejection can be treated with either increasing immunosuppressants or corticosteroid depending on the disease severity. Recurrent autoimmune hepatitis requires a slower taper and potentially continual use of additional immunosuppressants. However, corticosteroids have been successfully withdrawn in many patients after transplantation. Autoimmune promoters, such as polymorphisms of the genes producing cytokines, may facilitate direct cytotoxicity and regulate immunocyte activation. In patients that have progressive disease, tacrolimus may offer an advantage over cyclosporine-based immunosuppression. Because this is an exceedingly rare outcome, there are no definitive incidence rates reportable as of now. In addition to release of autoantigens from damaged tissues, a possible mechanism is molecular mimicry, in which exposures to viruses with autoantigens leads to cross-reactive immunity. Currently no risk factors have been identified, and the type of immunosuppression and indication do not appear to be implicated.

This was not always straightforward; the first cases, performed starting in 1967, resulted in early recurrence of tumor in the first months after transplantation, with early mortality in most cases. The Milan group showed in 1996 that transplantation of patients with a small tumor burden results in posttransplant survival similar to that of noncancer patients. This led to a broader adoption of neoadjuvant therapy as a bridge to transplantation, which has been shown to decrease dropout from the waiting list for progression of tumor. Whether neoadjuvant treatments have an effect on overall posttransplant survival is unclear. Evaluation of solid liver lesions has evolved to include various imaging technologies, and a multimodality approach is typically used to address them.
