Selective renal embolization or partial/total nephrectomy could additionally be lifesaving in the setting of acute haemorrhage impotence treatments natural order cialis soft 40 mg without prescription. In tumours of >3cm erectile dysfunction korea cialis soft 20 mg buy without prescription, the mToR (mammalian target of rapamycin) inhibitor everolimus can cut back tumour volumes by >50% in 64% of patients over 96wk erectile dysfunction 2 cialis soft 20 mg for sale, with acceptable toxicity erectile dysfunction drugs in pakistan cialis soft 40 mg generic online. Usually tan-coloured, lobulated, and strong; 7% are multifocal, 1�2% bilateral, and 10�20% contain calcification; 10�25% comprise cysts or are predominantly cystic. Array-based karyotyping performs well on paraffin-embedded tumours and can be utilized to identify characteristic chromosomal aberrations in renal tumours with difficult morphology. Grading is by the Fuhrman system (1 = properly differentiated; 2 = moderately differentiated; 3 and 4 = poorly differentiated), based on nuclear measurement, define, and nucleoli. Reports of spontaneous regression, extended stabilization, and full responses to immunotherapy support this. There has been a 38% improve in incidence over the past decade, presumably associated to incidental prognosis utilizing cross-sectional imaging. Paraneoplastic syndromes as a result of ectopic hormone secretion by the tumour occur in 30% of sufferers; these may be related to any illness stage (Table 7. Active surveillance and minimally invasive choices are mentioned within the subsequent section. Perceived advantages over radical nephrectomy include preservation of renal perform and reduced threat of cardiovascular occasions. The renal artery is clamped, and the kidney full of crushed ice (open technique) to keep away from heat ischaemia. Functional recovery occurs within hours after 20min of heat ischaemia, and days after 30min; it might take a quantity of weeks after 60min of clamping. Specific problems include urinary leak from the amassing system, which may require prolonged drainage or a ureteric stent placement to facilitate therapeutic, and hyperfiltration renal damage, which may finally require renal replacement therapy-proteinuria is a prognostic sign. Attempts at attaining cold ischaemia using renal artery or retrograde ureteric infusions, or crushed ice in endo-bags have proved troublesome and laborious. Advantages over open surgery include less blood loss, pain, reduced hospital keep, and faster return to normal exercise. Morbidity is reported in 8�38% of circumstances, together with pulmonary embolism (Pe) and poorly understood effects on renal operate. The surgical method is transperitoneal (good access to hilar vessels) or thoraco-abdominal (for very large or T3c/T4 tumours). Following renal mobilization (avoiding tumour manipulation), the ureter is split; ligation and division of the renal artery or arteries ought to ideally happen previous to ligation and division of the renal vein, to forestall vascular swelling of the kidney. Complications embrace mortality of up to 2% from bleeding or embolism of the tumour thrombus and bowel, pancreatic, splenic, or pleural damage. After partial nephrectomy, concern will also give consideration to recurrence in the remnant kidney. Post-operative prognosis the leibovich scoring system groups patients into low, intermediate, or excessive danger for improvement of metastasis at 1, 3, 5, 7, and 10y, based on tumour stage, dimension, nuclear grade, presence of necrosis, and regional nodal standing. This is especially helpful when deciding on sufferers for trials of adjuvant therapy. Prediction of development after radical nephrectomy for patients with clear cell renal carcinoma: a stratification software for prospective scientific trials. For every 1cm size improve, the estimated prevalence of metastasis will increase by three. Currently, the standard follow is to not advocate it, but, the place potential, patients ought to be recruited to studies investigating cytoreductive nephrectomy. Nephrectomy could also be considered together with resection of single or oligo-metastases in selected sufferers with healing intent, or to a minimum of delay the necessity for systemic remedy. Resection of a solitary or oligometastases is an appropriate choice for a small variety of patients, ideally a few months after nephrectomy, to ensure the lesion has remained solitary. Stereotactic radiotherapy or radiosurgery is useful for palliation of symptomatic metastatic lesions in bone and the brain and, together with surgery, for spinal cord compression. Active surveillance of small renal plenty: development patterns in early stage kidney cancer. The presence of none of those factors confers beneficial risk-median time to dying 20 months; 1�2 factors carry intermediate risk-median survival 10 months; >3 components carry poor risk-4 months median survival. Randomized studies within the 1990s demonstrated modest response rates (10�20%) after systemic immunotherapy, using these cytokines alone and in combination; toxicity could probably be severe. Responses have been more likely in sufferers with good performance status, prior nephrectomy, and small-volume metastatic burden. Complete responses are rare, and partial responses modest (30�40%); they also stabilize the illness in 730% of patients. Second-generation immunotherapy Recent advances in immune-oncology have the potential to rework the practice of medical oncology. Finally, studies are ongoing to explore the efficacy of immune-stimulatory vaccines containing dendritic cells and tumour-associated peptides. Pathology and grading the tumour usually has a papillary structure, however often solid. It arises inside the renal pelvis, much less regularly in one of many calyces or ureter. Spread is by direct extension, together with into the renal vein and vena cava; lymphatic spread to para-aortic, para-caval, and pelvic nodes; and bloodborne spread, most commonly to the liver, lung, and bone. The laparoscopic strategy focuses on mobilizing the kidney and upper ureter extraperitoneally; the lower ureter with the bladder cuff is dissected by way of a Gibson-type open incision, by way of which the complete specimen is retrieved. As for laparoscopic nephrectomy, benefits embody lowered post-operative ache and quicker restoration. The open approach makes use of both a long transperitoneal midline incision or separate loin and iliac fossa incisions. The whole ureter is taken with a cuff of the bladder because of the 50% incidence of subsequent ureteric stump recurrence. Percutaneous, segmental, or ureterorenoscopic resection/laser ablation of the tumour are the minimally invasive options for patients with a single functioning kidney, bilateral disease, or unilateral low-grade tumours of <1cm, or those that are unfit. This nephron-sparing method is much less more probably to be healing than definitive surgery, with as much as a 3rd of patients having recurrence. The following are acknowledged prognostic factors, in descending order of importance: � Tumour grade and stage. These information point out about half of patients identified have curable or controllable illness; therefore, 10y survival is around 50% for women and approaching 60% in men. Smokers have a 2- to 4-fold i danger of developing bladder most cancers, with subsequent recurrences and better mortality proportional to the quantity and period, compared to non-smokers. No proof for a hereditary genetic aetiology exists, though many somatic genetic abnormalities have been identified. The commonest cytogenetic abnormality is lack of chromosomes 9p, 9q, 11p 13q, and 17q. Activation/ amplification of oncogenes (p21 ras, c-myc, c-jun, erbB-2), inactivation of tumour suppressor genes (p53 mutations appear to worsen survival after treatment, retinoblastoma, p16 cyclin-dependent kinase inhibitor), and that i expression of angiogenic components. Tumour spread is: � Direct tumour progress to contain the detrusor, the ureteric orifices, prostate, urethra, uterus, vagina, perivesical fat, bowel, or pelvic aspect walls. This is poorly differentiated carcinoma, however confined to the epithelium and associated with an intact basement membrane. Histological grading was traditionally classified into: benign urothelial papilloma and nicely, reasonably, and poorly differentiated (G1, G2, and G3, respectively) carcinoma (1973 Who Classification). Most retrospective research, clinical trials, and tips are based on this classification. The 2004 system is more reproducible however is as but not proven to be of better prognostic worth than the 1973 system. Adenocarcinoma is uncommon, often solid/ulcerative and G3, and carries a poor prognosis. Adenocarcinoma is a long-term (10�20+ year) complication of bladder exstrophy and bowel implantation into the urinary tract, particularly bladder substitutions and ileal conduits after cystectomy. Secondary adenocarcinomas of the bladder principally come up by direct unfold, as mentioned previously. Four to 12% of patients >45y (risk rising with age) and 1�2% of those <45y with Vh have bladder cancer. Signs General examination might reveal pallor, indicating anaemia due to blood loss or continual renal impairment.

These high-activity/lower energy sources require much less shielding and deliver radiation at a excessive or low dose rate diabetic erectile dysfunction pump 40 mg cialis soft purchase otc. For permanent seed implants b12 injections erectile dysfunction generic 40 mg cialis soft overnight delivery, I-125 is often used as it has a low energy that can safely be implanted with out shielding necessities erectile dysfunction urinary tract infection cheap cialis soft 40 mg line. It usually is utilized in a multidisciplinary setting together with exterior beam chemoradiation to optimize treatment of the first site erectile dysfunction louisville ky 40 mg cialis soft purchase free shipping. However, for selected tumors with minimal danger of regional nodal involvement, it can be used as main stand-alone definitive treatment such as in small tumors of the lip or tongue. It can also be utilized as an adjuvant therapy after surgical resection or as salvage remedy. In addition, patients with altered mental standing that may intrude with treatment compliance are also suboptimal candidates. Patients must be able to self-care throughout brachytherapy therapy, together with management of tracheostomy, percutaneous endoscopic gastrostomy or nasogastric tube, and patient-controlled analgesia, as indicated. Patients ought to have a dental analysis prior to receiving brachytherapy to fabricate customized dental shields and spacers to protect the mandible from the implant. It offers the distinctive advantage of directly delivering high doses of radiation locally to tumors whereas largely sparing surrounding tissues as a result of fast dose fall-off. In appropriate setting, brachytherapy offers an organ and practical preservation different to surgical resection of oral cavity cancers. It is also a useful method for local radiation supply within the adjuvant or salvage settings. It was famous that a small quantity of radium left on the pores and skin resulted in ulceration on the site. In 1901, Danlos and Bloch handled nonmalignant pores and skin lesions with local software of unsealed radium sources. Its oncologic application soon adopted with the first reported radium therapy for cancer of the palate and pharynx in 1902 in Vienna. Interstitial brachytherapy could also be delivered with radioactive sources (typically Ir-192) threaded into catheters briefly implanted into the tumor volume. Surface mould applicators are commonly used to deal with exposed tumors located superficially. The technique of brachytherapy delivery has also developed from using inflexible sources of finite length like within the "Paris System" to employing flexible catheters with the afterloading technique. Paterson and Parker launched the idea of source loading rules to a single point with the Manchester system for cervical cancer in 1934. Inverse planning allows the planner to generate an idealized plan primarily based on the prescription and dose constraints for the target and organs at risk. The use of geometrical, volume, and inverse optimization forms the premise of optimum planning. Fine tuning to customise scientific goal volume coverage versus organ vulnerable to publicity could be achieved using handbook instruments that enable manipulation of the dose cloud by the radiation oncologist. Janeway printed a series of 24 patients handled from 1915 to 1917 for lip most cancers with superficial or deep tissue invasion. Since then, brachytherapy for lip most cancers has developed to include new techniques and technology. Brachytherapy has been employed alone or with exterior beam radiation as definitive therapy, adjuvantly for optimistic or shut surgical margins, or as salvage remedy. Jorgensen et al reported a big single-institution series of 869 circumstances of newly diagnosed carcinoma of the lip. Radium needles have been inserted transversely and longitudinally into the lesion in the lip. The European Curietherapy Group reported the most important series of 2,363 patients handled for lip most cancers from 23 facilities. In this multi-institutional report, iridium was discovered to have improved native management of 96. It is assumed that improved dosimetry and implant method contributed to improved therapeutic efficacy of iridium. Using versatile parallel Ir-192 wires, a imply dose of sixty five Gy was delivered for superficial tumors, and sixty eight Gy was delivered for tumors 5 mm. Increased lesion thickness 1 cm was found to be associated with a better recurrence price as a end result of poorer regional control. Guibert et al reported remedy of 92 sufferers using iridium wires and the Paris system afterloading method. For interstitial brachytherapy, prophylactic antibiotics are given to lower the danger of an infection at catheter insertion and surgical sites as nicely as pneumonia. Nutrition throughout therapy is run with a nasogastric or gastrostomy tube. A tracheostomy could also be necessary to keep a patent airway and forestall aspiration. Patients should be monitored closely for the period of brachytherapy therapy to ensure minimal displacement of the catheters and inspired to ambulate to reduce danger of deep vein thrombosis. During catheter elimination, the affected person might develop hemorrhage, which could be controlled with bidigital compression whereas the airway is protected with an inflated tracheostomy cuff. Patients should be discharged with enough analgesics and applicable training 275 Brachytherapy for Oral Cavity Cancer Table 34. Patient-reported functional results have been passable for 99% of sufferers, and cosmetic outcomes had been passable for 92%. Another trendy single-institution collection included 89 nodenegative lip cancer circumstances, 10 after wedge-excision (6 microscopic positive margin, four macroscopic residual disease). Five-year disease-free survival was 82% for the whole cohort, 100 percent for T1 and 89% for T2�T3 illness, respectively. Patient-reported cosmesis (deformity, telangiectasia, dyspigmentation, and alter in pores and skin texture) was good for 77% of sufferers, fair for 21%, and one patient reported poor end result. It was discovered that enormous tumors of > 2 cm thickness or previous surgery was related to worse cosmesis. The mildew ready with thermoplastic sheet and dental wax held catheters in position to the tumor surface. It was discovered that the speed of complications increased with therapy thickness > 1. Feldman et al reported a way utilizing catheters embedded in a personalized surface mildew that distances the lip from adjacent mandible or maxilla, and no osteonecrosis was observed. Toxicity Acute toxicities associated with brachytherapy for lip cancer might embody desquamation, mucositis, and ache within the area being treated. The commonplace therapy for early stage disease restricted to the tongue is surgical resection. It can be utilized after surgical procedure if opposed pathologic danger factors point out a need for adjuvant therapy. For domestically advanced disease, brachytherapy could also be added as an area enhance with definitive external beam chemoradiation to achieve dose-escalation. Two-year native control and cause-specific survival rates have been eighty two and 83%, respectively. Patients with lower T stage had lower incidence of neck nodal failure after brachytherapy treatment with charges of 33, fifty five, and 50% for T1, T2, and T3 tumors, respectively. Patients with T1�2N0 most cancers additionally had improved causespecific survival of 88% compared to 79% for T3N0 cancers. Local control charges have been 70�80%, with larger rates of local control for smaller lesions at 85, seventy seven, and 50% for T1, T2, and T3 tumors, respectively, corresponding to historic outcomes from massive surgical collection such as that from the Memorial Sloan-Kettering Cancer Center. The majority of instances had been handled with definitive radiation, and 47 instances had been handled postoperatively. Brachytherapy was delivered utilizing parallel catheters spaced 10�12 mm aside targeting residual palpable tumor and pretreatment gross tumor volume. Four-year native control, cause-specific survival, and regional management rates had been 80, 68, and 76%, respectively. All patients skilled acute mucositis that resolved 4�6 weeks after treatment completion. Late complications including mucositis and dysphagia were observed in 5 sufferers, and one case of osteoradionecrosis was observed. Multidisciplinary tumor board dialogue proposed induction chemotherapy to assess response for potential definitive chemoradiation. Interstitial implant was carried out with six looped brachytherapy catheters placed in the complete oral tongue and left base of tongue spaced roughly 1�1.

These perforators are preserved together with a small muscle cuff of flexor pollicis longus to enhance periosteal perfusion wellbutrin erectile dysfunction treatment buy 20 mg cialis soft amex. However what causes erectile dysfunction cialis soft 40 mg buy, care must be taken to choose sufferers with enough vascular provide and with limited threat for osteoradionecrosis impotence nhs 40 mg cialis soft quality. In addition impotence homeopathy treatment safe 20 mg cialis soft, selection of patient candidates should keep in mind the necessity for potential post operative radiation therapy which can compromise osseointegration and make patients poor candidates for upfront dental implantation. Some patients could also be at too nice a risk for late onset vascular compromise to the grafted fibular bone with the addition of dental implants. These implants have been demonstrated to sufficiently combine in a rabbit mannequin with marginal mandibular defects. Briefly, dental rehabilitation requires the previously described establishment of soppy tissue protection to the occlusal surfaces of the maxilla and mandible. The implantation of everlasting dentition with dental implants, when possible, over detachable obturator or denture gadgets has become the gold commonplace. It is essential to be conscious that, for the majority of patients, dental rehabilitation first requires revision surgical procedure to any primary reconstructive effort to have the ability to prepare the site for potential prosthodontic remedy. For instance, cumbersome flaps could need to be thinned or gentle tissue could even have to get replaced with thinner options similar to skin graft so as to enhance the definition of bony landmarks, deepen sulci, and reduce gentle tissue laxity or redundancy for improved stability of prosthetics. The removal of redundant or cumbersome soft tissue may be required to enhance entry to bone in which dental implants may be placed. For instance, typically patients may be asked to keep away from mastication, eat only a delicate diet, and even eat nothing by mouth for some period to permit for therapeutic and stabilization of the reconstruction. In this case, alternative dietary methods similar to nasogastric feeding may be required. Chlorhexidine oral rinse has been demonstrated to decrease oral cavity micro organism in head and neck patients. Alternatively, salt and soda or regular saline rinses are additionally prescribed to postoperative patients to soothe and help with oral hygiene after oral cavity surgery. Gentle mechanical cleansing with delicate swabs may be essential to clean desquamating debris from skin bearing flaps. The oral cavity could be visualized simply for assessment of flap well being, and frequently pencil Doppler is used to monitor blood circulate by way of the flap.

Accurate analysis and staging require thorough medical examination and appropriate imaging workup. Surgical remedy is the first line of administration and may be technically difficult to resect and reconstruct. There is extensive geographical variation within the incidence of oral cancer, with the areas of South and Southeast Asia (India, Sri Lanka, Pakistan, and Taiwan), parts of Western (France) and Eastern Europe (Hungry, Slovenia, and Slovakia), elements of Latin America and the Caribbean (Puerto Rico, Brazil, and Uruguay), and Pacific regions (Papua New Guinea and Melanesia) characterised by greater incidence than the relaxation of the world. In international locations like India, Sri Lanka, Pakistan, and Bangladesh, oral cancer is the commonest most cancers and constitutes 25% of all new cancers. Concomitant alcohol use has synergistic effect, further increasing the danger of oral cavity most cancers by 10- to 15-fold.

Hatton Intrauterine development restriction might happen in a symmetric or asymmetric method. Evaluation of restriction is predicated on ultrasonic measurement of fetal head and belly circumferences in contrast with gestational age. Imaging: Ultrasonography with fetal biometry in contrast with curves specific to the location and population served. The diagnosis must also be based on serial examinations that present details about the growth of the person fetus. Special Tests: When found in superior gestations: fetal nonstress and contraction stress testing or biophysical profiling. The function of Doppler flow research continues to be evaluated and is reliable solely when placental dysfunction is the trigger of the expansion restriction. Early intrauterine insults usually have a tendency to result in symmetric growth restriction; later insults lead to asymmetry. Similarly, intrinsic factors generally trigger symmetric restriction; extrinsic elements generally trigger asymmetric restriction. The most instant fetal morbidities are delivery asphyxia, meconium aspiration, sepsis, hypoglycemia, hypocalcemia, hypothermia, polycythemia, thrombocytopenia, and pulmonary hemorrhage. Expected Outcome: With early detection, progressive fetal progress can usually be achieved, although many pregnancies might require early supply or other interventions to guarantee fetal well-being. A randomized trial using ultrasound to identify the high-risk fetus in a low-risk population. Pathologic Findings Reduced fetal fats shops and decreased overall dimension compared with that expected for gestational age. Early delivery is often needed (the majority of fetal deaths occur after 36 weeks of gestation). Activity: No restriction except as dictated by maternal disease or fetal condition. How helpful is uterine artery Doppler flow velocimetry in the prediction of pre-eclampsia, intrauterine progress retardation and perinatal death Intrauterine growth restriction: new ideas in antenatal surveillance, diagnosis, and management. Patients in danger because of maternal disease should have early assessment of fetal development (biparietal diameter, head circumference, belly circumference, and femur length) with frequent reassessment because the pregnancy progresses. Possible Complications: Progressive deterioration of fetal standing and intrauterine fetal demise. The risk for opposed end result is proportional to the severity of progress restriction present. Description: Multiple gestation is two or extra fetuses that coexist throughout the identical gestation. The enhance in multiple births is considered to be due to the use of fertility medication and an increased rate of childbearing in ladies older than 30 years, who are more probably to conceive multiples. Multiple gestations are answerable for a disproportionate share of perinatal morbidity and mortality. They account for 17% of all preterm births (before 37 weeks of gestation), 23% of early preterm births (before 32 weeks of gestation), 24% of lowbirth weight infants (<2500 g), and 26% of very-low-birth weight infants (<1500 g). Hospital costs for women with a number of gestations are on a mean 40% higher than those for women with gestational-age-matched singleton pregnancies due to their longer length of stay and elevated rate of obstetric problems. Predominant age: Reproductive age (becomes extra common with increasing maternal age; four-fold enhance from the age of 15 to 35 years). Workup and Evaluation Laboratory: No special evaluation indicated, though because of the upper incidence of gestational diabetes, screening is of greater significance. Imaging: Ultrasonography (considered definitive; reduces the rate of undiagnosed multiple gestation from 40% to <5%). Radiographic studies are typically inadequate to set up the presence or well being of a multiple pregnancy, making routine use of X-rays undesirable. Special Tests: Genetic amniocentesis may be thought-about (twin pregnancies have twice the speed of abnormalities: monozygotic = 2%�10% rate). Dizygotic a number of gestations occur when there are multiple ova launched and fertilized (naturally or through assisted ovulation. Risk Factors: Ovulation induction (clomiphene remedy: 5%�10% a number of gestation rate), increased maternal age, parity, weight and height, African-American race. Pathologic Findings Examination of the placenta can determine the type of pregnancy. Specific Measures: Antenatal testing, prompt intervention for threatened preterm labor. Bed rest is unproven and carries an elevated danger of vascular thromboembolic occasions. The use of progestational brokers to cut back the danger for preterm birth has been tested only in singleton pregnancies. Some issues of multiple gestation could additionally be decreased by increased surveillance and monitoring. Possible Complications: Perinatal morbidity and mortality is two to five occasions larger than for singleton gestations. Other complications: intrauterine progress restriction (12%� 47% versus 5%�7% in singletons) or discordant growth, cord accidents, polyhydramnios, congenital anomalies (two instances increase), malpresentation. Monozygotic twins have a 1% incidence of monoamniotic sacs that carries a 50% fetal mortality due to cord entanglement or conjoined twins. One-fifth of triplet pregnancies and one-half of quadruplet pregnancies lead to a minimum of one youngster with a serious long-term handicap, such as cerebral palsy. Cerebral palsy happens 17 occasions extra often in triplet pregnancies and greater than 4 instances more often in twin pregnancies than in singleton pregnancies. When matched for gestational age at delivery, infants from multifetal pregnancies have a nearly three-fold greater danger of cerebral palsy. Maternal Complications: Abruptio placenta, placentae previa, preeclampsia, anemia, hyperemesis gravidarum, pyelonephritis, cholestasis, postpartum hemorrhage, increased operative supply fee. Most Common Presentation: Vertex/vertex (43%), vertex/other (38%), twin A different (19%). The North American Fetal Therapy Network consensus statement: prenatal surveillance of uncomplicated monochorionic gestations. Often outlined as a single deepest pocket of amniotic fluid of two cm or less or an amniotic fluid index (sum of most vertical fluid pocket in each quadrant not containing umbilical cord or fetal extremities) of 5 cm or less on ultrasonography. Prevalence: Rare in early pregnancy, frequent in postterm pregnancies (12%�25% at 41 weeks) and during labor following rupture of the fetal membranes. Generally related to a discount in fetal urine manufacturing (renal agenesis, urinary tract obstruction, and fetal death), persistent amniotic leak or preterm rupture of the membranes (35%), maternal disease (hypertension, diabetes, uteroplacental insufficiency, preeclampsia). Risk Factors: Fetal chromosomal or congenital abnormalities (approximately 50%; see Box 233. Borderline values should at all times be rechecked before any intervention is undertaken. Possible Complications: Amniotic band syndrome (including partial limb amputation), pulmonary hypoplasia, untimely labor, clubfoot, meconium-stained amniotic fluid, umbilical wire compression, and fetal dying. The prognosis is inversely associated to gestational age: the sooner the oligohydramnios happens, the extra serious the outcome. Specific Measures: Amnioinfusion (the introduction of normal saline by way of an intrauterine catheter positioned via the partially dilated cervix throughout labor) has been used to scale back the incidence of umbilical twine compression during labor. A randomized scientific trial of the intrapartum evaluation of amniotic fluid quantity: amniotic fluid index versus the one deepest pocket technique. Prophylactic amnioinfusion for intrapartum oligohydramnios: a meta-analysis of randomized controlled trials. Perinatal outcome and amniotic fluid index within the antepartum and intrapartum durations: a metaanalysis. Amniotic fluid index versus single deepest vertical pocket as a screening test for preventing opposed being pregnant outcome. Expected Outcome: Generally good-25%�30% of sufferers full 36 weeks of gestation despite labor or repetitive bleeding.
