In vivo genome editing of the albumin locus as a platform for protein replacement therapy. Class I molecules are coexpressed on nearly all nucleated cells and platelets and are anchored on them via the transmembrane portion and the short cytoplasmic tail of the -chain only. The amino acid residues forming this cleft are very polymorphic and are particularly immunologically relevant in the -helical regions. As the protein folds into the tertiary structure, some of the hypervariable regions assume a location pointing into the cleft in an optimal position for interaction with the processed antigen. These same hypervariable regions form the molecular basis of alloreactivity in tissue transplantation. These antigenically relevant differences constitute the human leukocyte antigens originally recognized by Dausset and Payne (see "Historical Iter towards Histocompatibility Definition"). A stable, inherited polymorphism gives rise to alternative forms of the protein, the alleles. The polymorphism is clustered into three or four discrete hypervariable regions, which become more evident when the amino acid sequences of these alleles are aligned. If the inherited maternal and paternal alleles happen to be the same, the person is homozygous at that locus. Homozygosity is rarely found and is frequently generated by descent in couples in which the two partners are somewhat related. Note the immunoglobulin-fold structure of each membrane proximal domain, including the 2-microglobulin molecule. In 1967, Ceppellini coined the term haplotype (haplous in Greek for "single") to define each genetic unit inherited from one or the other parent [11]. Only some of the nonclassical class I genes are shown; the functions of only some of their proteins are known. Haplotype recombination may occur during parental gametogenesis by crossing over during meiosis. Consequently, the definition of individuals as heterozygous or homozygous at certain loci. By convention, the paternal haplotypes are designated as a and b and the maternal haplotypes as c and d. Only a family study and the analysis of allele segregation in it can positively elucidate both haplotypes of an individual. The class I genes present at the A, B, and C loci encode molecules that can efficiently present "endogenous" antigenic peptides to cells matured in the thymic environment ("T" cells) promoting positive and negative selection. Besides the large multifunctional proteases and transporter associated with antigen processing­encoding genes, others. Although with different efficiency, macrophages, monocytes, dendritic cells, and mature B cells are all able to phagocytose foreign molecules, thus capturing "non-self " proteins invading our body and enzymatically cleaving them into smaller segments called peptides. The peptide complexed with the so-called binding groove is then exposed at the cell surface. Cytokines are secreted cellular hormones that can inhibit or stimulate other cells to become activated. The search for histo- (histos in Greek for "tissue") compatibility became the original goal of these studies. If, on the one hand, chimeras can represent an artistic version of a successful xenotransplantation intervention. Fra Angelico (1387­1455), the painter, here represented the miracle performed by Saints Cosmas and Damian in Constantinople as narrated in a third-century legend. According to the legend, these twin brothers, one a physician and the other a surgeon, replaced the cancerous leg of a white church sacristan with a healthy limb from a recently deceased Moor. The story is told that the sacristan walked around for the rest of his life with one white leg and one black leg [20­22]. There is, however, evidence that transplantation surgery was successfully performed more than 2000 years ago by ancient Hindu vaidya [23]. Calinzio added that: "for a time the new nose functioned well," then "suddenly grew cold," "turned blue," and "eventually fell off. Today we know that the difference between these successful and unsuccessful transplants is that the first was an autologous transplant. We had to wait until the beginning of the twentieth century to find evidence of a fresh new look to the transplantation problem. In 1912 George Schöne clearly summarized conclusions he gathered from different transplant attempts mostly performed in animals. The "laws of transplantation" were so defined: (1) autografts generally succeed, (2) allografts usually fail, and (3) xenografts invariably fail. Twenty-five years later Peter Gorer, an expert on tumor transplantation in mice, defined the scientific basis of the postulated Schöne blood relationship [25]. To determine what was different between the accepting versus the rejecting strains, Gorer performed tumor transplants in F1, F2, and backcross progeny of the three inbred strains of mice. On the basis of his knowledge of the blood groups, Gorer also attempted to distinguish the tumor-susceptible from the tumor-resistant animals on the basis of mouse erythrocyte agglutination driven by human serum. Furthermore, rabbit anti-mouse erythrocyte sera were sufficient to define three mouse red blood cell antigens. Using congenic strains of mice, Gorer and Snell were able to determine that engrafted tumors were most likely able to "take" when the recipient mouse was of the same strain as the donor [28]. More importantly, they also realized that survival of donor tissue was not limited to tumors but applied to any graft including skin. Also, donor-specific antibodies first noted by Gorer in the graft-rejecting recipient were induced not only by tumor grafting but also by any other tissue graft or blood transfusion [21]. By appropriate genetic crosses and backcrosses among their congenic inbred strains, Snell and Gorer identified a number of genetically independent loci controlling these immune responses, which they designated H for histocompatibility, followed by an Arabic numeral in the order of discovery. He also came to the conclusion that, while autografts succeed, allografts actually fail after an initial period of survival. A second allograft from the same donor did not experience the latent period of the first; rather, it rejected in an accelerated fashion. The survival of a second graft from a different donor was instead similar to that of the original graft, rejecting only after a latent period. Because the accelerated rejection could also be induced by injection into the recipient of donor leukocytes prior to engraftment, he hypothesized that "destruction of the foreign epidermis was brought about by a mechanism of active immunization. In 1954, the first successful kidney transplant was performed between monozygotic twins for which immunosuppression was not necessary [31]. In 1959, the same team used an efficient immunosuppressive regimen to perform the first kidney graft between unrelated individuals [32]. The observations that antibodies against transplantation antigens could be generated as the result of an immune response against transfused blood components suggested the possibility of identifying human histocompatibility antigens through serologic methods. In 1958, Jean Dausset produced the first human histocompatibility antiserum through deliberate immunization of one blood donor with leukocytes from another [33]. This antiserum agglutinated the white blood cells of about 60% of his French donor panel. Concurrently, Payne and Rolfs showed that the sera from multiparous women often contained leukoagglutinins [34]. This technique uses as target cells a suspension of pure and viable lymphocytes that have been separated from whole peripheral blood by using density gradient separation. The lymphocytes are incubated with the panel of alloreactive antisera and a source of complement (C), usually rabbit serum. When a specific antigen­antibody complex is formed, C is fixed and activated, resulting in cell lysis. Following the addition of a vital dye, the percentage of dead versus live cells can be visualized with phase contrast microscopy. Originally, it was the responsibility of the individual tissue typing laboratory to procure, test, and maintain quality control of the antisera used in testing. This was achieved by organizing international workshops that have been held every 3­4 years since 1963. These international workshops, originally aimed at sharing and consequently standardizing alloantisera, target cells or cell lines, and technical procedures, soon became the forum for recognition of new loci, the definition of new alleles, the adoption of the standard methods, and the acceptance and then the use of a common nomenclature. Today, sera can be obtained locally or through national or international serum exchange programs. All accredited histocompatibility laboratories are required to adhere to rigorous standards regarding reagents, protocols, and quality assurance set forth by the American Society for Histocompatibility and Immunogenetics. In addition, most laboratories participate in several proficiency testing programs administered by such agencies as the College of American Pathologists. In 1977, the development of mouse anti-human monoclonal antibodies was seen as the best alternative source to increase specificity and have an unlimited supply of standardized reagents [38]. Their use, however, is not yet widespread due to the limited number of "private" specificities recognized by the mouse, which reacts preferentially against "public" specificities, that are different between mice and humans. Trays containing only monoclonal antibodies that allow a relatively informative typing are commercially available. Despite its limitations, the microlymphocytotoxicity test remained for years the most popular test for clinical use to provide a moderate level of typing resolution in one working day.

Whereas these same pathways act to inhibit sympathetic and pudendal outflow to the urethra skin care heaven coupon purchase decadron 4 mg amex, maintaining urethral relaxation skin care 35 year old buy decadron 1 mg with mastercard. Detrusor contraction raises the intravesical pressure sufficiently to allow the bladder from emptying acne girl discount decadron 0.5 mg visa. Urge incontinence is believed to be caused by any disruption to the well-coordinated process of micturition skin care 40s purchase decadron 1 mg otc. A commonly used treatment regimen targets the muscarinic receptors of the bladder acne 9 dpo generic decadron 1 mg on-line. The support structures of the bladder and/or urethra may alter the system in such a way that urethral closure pressure is no longer maintained, or no longer exceeds intra-abdominal pressure during strenuous activity, which creates a pressure gradient favoring loss of urine, albeit involuntarily. With aging, bladder capacity decreases, ability to inhibit urination declines, involuntary bladder contractions (detrusor overactivity) occur more often, and bladder contractility is impaired. In postmenopausal women, decreased estrogen levels lead to atrophic urethritis and atrophic vaginitis and to decreasing urethral resistance, length, and maximum closure pressure. In younger patients, incontinence often begins suddenly, may cause little leakage, and usually resolves quickly with little or no treatment. Often, incontinence has one cause in younger patients but has several in the elderly. Conceptually, categorization into reversible (transient incontinence) or established causes may be useful. Diagnostic Approach the aim of diagnosis is to identify the type of incontinence. In most instances, urinary incontinence are diagnosed on the basis of history alone. The main complaint of the disorder is almost always confirmed by physical signs or clinical testing. However, most patients are embarrassed to mention incontinence and do not volunteer information about it. So women should therefore be screened with a question such as "Do you ever leak urine Particular attention to the obstetric and gynecologic history is important to determine any predisposing risk factors. The obstetric risk factors include number of pregnancies, mode of delivery, history of assisted delivery and obstetric trauma. Lightly tapping the clitoris or brushing the labia majora should produce a reflex contraction of the external anal sphincter muscle History of child hood enuresis Nocturia Fecal incontinence Family history of incontinence Mental state is also evaluated particularly in elderly women dementia, depression and other cognitive impairment may be linked with incontinence. History of back injury and fall Use of drugs such as antihistamines, antidepressants, and antipsychotics, calcium channel blockers and alfa adrenergic agonists Chronic medical conditions, such as chronic cough, multiple sclerosis, chronic heart failure, and diabetes mellitus. Neurologic examination involves assessing mental status, gait, and lower extremity function and checking for signs of peripheral or autonomic neuropathy, including orthostatic hypotension. Neck and upper extremities should be checked for signs of cervical spondylosis or stenosis. The spinal column should be checked for evidence of prior surgeries and for deformities, dimples, or hair tufts suggesting neural tube defects. Pelvic examination: Pale, thin vaginal mucosae with loss of rugae indicate atrophic vaginitis. Urethral hypermobility can be seen during coughing when the posterior vaginal wall is stabilized with a speculum. Presence of cystocele, an enterocele, a rectocele, or uterine prolapse suggests pelvic floor weakness. Pooling of urine in the vagina during examination may be due to the presence of any fistulous tract, particularly in patients who have undergone pelvic surgery or pelvic radiation. A bimanual examination also provides valuable information about the size and position of the pelvic organs. Rectal examination can identify fecal impaction, rectal masses and sphincter tone. The bladder must be full; a patient sits upright or close to upright with the legs spread, relaxes the perineal area, and coughs vigorously once. Immediate leakage that starts and stops with the cough confirms stress incontinence. Delayed or persistent leakage suggests detrusor over activity triggered by the cough. If cough triggers incontinence, the maneuver can be repeated while the examiner places 1 or 2 fingers inside the vagina to elevate the urethra (Marshall-Bonney test); incontinence that is corrected by this maneuver may respond to surgery. Results can be false-positive if patients have an abrupt urge to void during the test or false-negative if patients do not relax, the bladder is not full, the cough is not strong, or a large cystocele is present. In presence of large cystocele, the test should be repeated with the patient supine and the cystocele reduced, if possible. Investigations: Urinalysis and postvoid residual urine estimation are initial tests to order. Urinalysis can help to identify underlying medical conditions that may contribute to urinary incontinence. Urine culture, blood urea nitrogen and serum creatinine estimation may be required in some women. Postvoid residual measurement assesses the volume of urine in the bladder after a void. It is measured by sterile catheterization or ultrasound with good accuracy, and can differentiate between adequate bladder emptying and urinary retention. Postvoid residual volume plus voided volume estimates total bladder capacity and helps to assess bladder proprioception. A post void residual urine volume < 50 mL is normal; < 100 mL is usually acceptable in patients > 65 but abnormal in younger patients; and > 100 mL may suggest detrusor underactivity or outlet obstruction. Urodynamic testing is indicated when clinical evaluation combined with the appropriate tests is not diagnostic or when abnormalities must be precisely characterized before surgery. Cystometry measures bladder pressure during filling and can be undertaken by any clinician. Sterile water is introduced into the bladder in 50 mL increments using a 50 mL syringe and a 12- to 14-F urethral catheter until the patient experiences urgency or bladder contractions, detected by changes in fluid level in the syringe. If < 300 mL causes urgency or contractions, detrusor overactivity and urge incontinence are likely. Pressure-flow video studies, usually done with voiding cystourethrography, can correlate bladder contraction, bladder neck competency, and detrusor-sphincter synergy, but equipment is not widely available. Clinical pearl: In most cases, a preliminary diagnosis of urinary incontinence can be made and treatment initiated based on findings of the medical history, physical examination and simple laboratory testing. Treatment Improvement of pelvic muscle function and bladder retraining, where appropriate, can also help For stress incontinence, pharmacotherapy and surgery can be considered in severe cases. For urge incontinence, additional treatment may include pharmacotherapy, neuromodulation, or onabotulinumtoxin A. For mixed incontinence, treatment should be determined by the predominant symptoms or according to urodynamic test results. General measures: Patients may benefit from bladder training (to change voiding habits) and changes in fluid intake. Prompted voiding is used for cognitively impaired patients; they are asked about every 2 h whether they need to void or whether they are wet or dry. A voiding diary helps establish how often and when voiding is indicated and whether patients can sense a full bladder. Behavioral approaches and lifestyle changes are the preferred initial treatment for this condition. Patients must contract the pelvic muscles (pubococcygeus and paravaginal) rather than the thigh, abdominal, or buttock muscles. The muscles are contracted for 10 sec, then relaxed for 10 sec 10 to 15 times tid. In women < 75 yr, cure rate is 10 to 25%, and improvement occurs in an additional 40 to 50%, especially if patients are motivated; do the exercises as instructed; and receive written instructions, follow-up visits for encouragement, or both. Pelvic floor electrical stimulation is an automated version of Kegel exercises; it uses electrical current to inhibit detrusor overactivity and contract pelvic muscles. Advantages are improved compliance and contraction of the correct pelvic muscles, but benefits over behavioral changes alone are unclear. Clinical pearl: All incontinent patients should be offered pelvic floor exercises because they supplement all forms of treatment and have no adverse side effects. Some patients benefit from a biofeedback session in order to correctly identify and contract appropriate muscle group. Drugs Pharmacologic Agents for Urge Incontinence Pharmacologic agents may improve detrusor overactivity by inhibiting the contractile activity of the bladder. Medications used include anticholinergics, tricyclic antidepressants, and musculotropic drugs. For urge incontinence with detrusor overactivity, oxybutynin and tolterodine are preferred treatments. If these treatments are ineffective, solifenacin, trospium, darifenacin, fesoterodine, and propantheline may be used. Pharmacologic Agents for Stress Incontinence In stress incontinence caused by urethral sphincter insufficiency, the first-line pharmacologic therapy is pseudoephedrine, if there are no contraindications. Estrogen can be used as an adjunct in postmenopausal women with stress incontinence. Imipramine, tricyclic antidepressant, has both anticholinergic and alfa-adrenergic properties and is useful in treating both urge and stress urinary incontinence by suppressing bladder contraction and increasing urethral contracti- Table 28. Estrogen causes engorgement of the periurethral blood supply and subsequent thickening of the urethral mucosa. While the tension-free vaginal tape sling is a nonabsorbable polypropylene mesh, and concern may exist regarding erosion and/or infection of this material; to date, few cases have been reported. Periurethral bulking is used when stress incontinence exists in the absence of urethral hypermobility, as second-line therapy after failed anti-incontinence surgery, or in patients who are poor surgical candidates. Many consider glutaldehyde cross-linked bovine collagen the gold standard bulking agent. Autologous fat, usually harvested from the lower abdomen, has been shown to be comparable to placebo. Macroplastique is a silicone polymer that has shown very promising results, although long-term results are pending. Clinical pearl: Stress incontinence may be treated surgically but behavioral treatment (including pelvic floor exercise) is first line treatment. Surgery is indicated if conservative treatment fails or patient requests more definitive therapy. Other Considerations Neuromodulation is a newer treatment option that has been used in the management of overactive bladder (detrusor overactivity) refractory to pharmacotherapy. Injection of onabotulinumtoxin A (formerly known as botulinum toxin type A) into the 286 Essentials in Gynecology bladder wall has also been shown to be effective for detrusor overactivity. This may be considered as an alternative to neuromodulation if pharmacotherapy is unsuccessful. Transurethral radiofrequency therapy is a nonsurgical in-office treatment for patients with stress urinary incontinence without intrinsic sphincter deficiency. It may be offered to the patient who cannot undergo surgery due to either physical or time constraints. Radiofrequency is used to denature and remodel collagen at the bladder neck, resulting in decreased elasticity and compliance, reducing exertion-related urine loss. Stress incontinence: Stress incontinence is losing urine during physical activity, such as coughing, sneezing, laughing, or exercise. Urge incontinence: Urge incontinence is the strong, sudden need to urinate due to bladder spasms or contractions. Cystometry: Cystometry is a test of bladder function in which pressure and volume of fluid in the bladder is measured during filling, storage, and voiding. Urodynamic study: Urodynamics is the investigation of the function of the lower urinary tract with regard to bladder filling/storage and emptying.

From her fifth day following child birth she has noticed continuous passage of urine and she has no urge to pass urine. On gynecological examination, her perineum is wet with urine smell and a large fistula of 3 cm diameter was noted in anterior vaginal wall. Regardless of the etiopathology, physically, psychologically and socially, it is major source of distress for the patient due to continuous urine leakage through vagina. This results in tissue necrosis of vesicovaginal wall due to ischemia which ultimately sloughs out resulting in development of fistula formation. Numerous authors highlight the risk of various types of bladder trauma during pelvic surgery. Such injuries include unrecognized intraoperative laceration of the bladder, bladder wall injury from electrocautery or mechanical crushing, suture placement through bladder wall and the dissection of the bladder into an incorrect plane, causing avascular necrosis.

Methods to identify abnormal area of the cervix: A cervical biopsy is usually done after a procedure called as colposcopy skin care zo purchase 1 mg decadron mastercard. A colposcopy allows the gynecologist to do a detailed examination of the tissues in the cervix so as to identify abnormal or diseased tissues skin care gadgets cheap decadron 1 mg buy on-line. Colposcopic examination is neither needed nor particularly effective for a gross cervical lesion skin care at 30 buy discount decadron 4 mg online, but can be helpful when there is a small surface lesion to identify the most abnormal area for directed biopsies acne free cheap decadron 1 mg otc. There are two well-known methods that can identify an abnormal area of the cervix skin care during winter cheap decadron online. The first method A cervical biopsy is an operative procedure performed to remove tissue from the cervix for histopathological examinations. Applying 3- to 5-percent acetic acid to mucosal epithelium results in the acetowhite change characteristic of neoplastic lesions as well as some non-neoplastic conditions. Lugol iodine solution stains mature squamous epithelial cells mahogany in estrogenized women due to high cellular glycogen content. Due to attenuated cellular differentiation, dysplastic cells have lower glycogen content and fail to fully stain, appearing various shades of yellow. The procedure, however, can be done using general, regional, or local block anesthesia. Steps of Operation After emptying bladder patient is placed on the operation table in the lithotomy position. An aseptic solution is applied to the vulva and vagina and appropriate sterile drapes are placed. Alternately an iodine solution may be used to coat the cervix, called the Schiller test. The type of biopsy performed will be determined by the size, shape, location, and other characteristics of the abnormalities. A vulsellum or Allis tissue forceps may be used to hold the cervix so to steady for the biopsy. For a punch biopsy, one or more small samples of tissue will be removed using a punch biopsy forceps. It is important to obtain a specimen where frank stromal invasion can be demonstrated, not from the exophytic portion where no benign stroma is present. Cells from the inside of the cervical canal may be sampled with an endocervical curette or an endocervical brush. For a cone biopsy, a larger cone-shaped piece of tissue is removed from the cervix. With the cold knife cone biopsy, a laser or a surgical scalpel is used to remove tissue. Bleeding from the biopsy site may be treated with electrocauterization (use of a probe with high frequency electrical signals to stop bleeding) or sutures, or packing the vagina with pressure dressing. Possible complications may include: Infection Bleeding In addition, cone biopsies may increase the risk for infertility and miscarriage because of the changes and scarring in the cervix that may occur as a result of the procedure. Identify the instruments and mention their use 356 Essentials in Gynecology Bibliography 1. Surgery in oncology carries more risks as geriatric patients, who may have multiple medical problems. There are two groups of indications for gynecological surgery: absolute-when surgery must be undertaken, when its cancellation is lifethreatening, and relative-when surgery can be postponed till the most appropriate occasion for its performing. Before making a decision on surgery, one of the three requirements must be fulfilled: relief of pain and suffering, preservation of life, correction of an existing deformity. If none of the three goals can be achieved by surgery, the surgery should be given up. The main objective of the preoperative assessment is to make sure that the patient is fit for the appropriate surgery and that the patient understands the indications, benefits, risks, and alternatives for the planned procedure. Preoperative consultation with an anesthesiologist is important for the medically compromised patient. Preoperative testing: Preoperative testing requires some routine preoperative laboratory tests and additional specialist examinations guided mostly by positive findings on the history and physical examination. For patients older than 40 years, laboratory analyses of the blood involves blood group determination, complete blood count, bleeding and coagulation time. Renal function is checked (urea, creatinin) and liver function as well 357 358 Essentials in Gynecology (bilirubin, serum alanine-aminotransferase, serum aspartate aminotransferase). A pregnancy test is usually done for women of reproductive age to exclude pregnancy. Antibiotics before gynecologic surgery: Prophylactic use of antibiotics have been found to be more successful for vaginal compared to abdominal operations. A recommended regimen for patients undergoing vaginal hysterectomy, abdominal or radical hysterectomy consists of a dose of i. Reduction in the number of pathogenic flora in the colon reduces the risk of infection if bowel surgery is performed. Mechanical bowel preparation with oral gut lavage using an agent such as polyethylene glycol electrolyte solution (Peglec) and a clear liquid diet for 24 hours the day before surgery is commonly used. Antihypertensive and thyroid medications should be taken with a sip of water on the morning of surgery. Below-the-knee elastic stockings and pneumatic compression devices may be used for patients undergoing gynecologic surgery. Information regarding the possibility and risk of a blood transfusion must be part of the informed consent procedure. Prophylaxis for subacute bacterial endocarditis: Women undergoing surgery with cardiac disease are candidates for prophylaxis for subacute bacterial endocarditis. Prophylaxis is recommended only for those in the highand moderate-risk categories. Different portions of the uterus, as well as other organs, may be removed at the same time. Types of Hysterectomy Total hysterectomy: It includes the removal of the entire uterus, including the body and the cervix, but not the tubes or ovaries. Subtotal hysterectomy (supracervical hysterectomy): Removal of the body of the uterus while leaving the cervix intact. Hysterectomy with salpingo-oophorectomy: Includes the removal of one or both ovaries, and the fallopian tubes, along with the uterus. Major Operations in Gynecology 359 Radical hysterectomy includes the removal of the uterus, cervix, the top portion of the vagina and parametrium (most of the tissue that surrounds the cervix in the pelvic cavity), and may include the removal of the pelvic lymph nodes. Uterine leiomyomas Symptomatic adenomyosis Symptomatic endometriosis Pelvic inflammatory disease Chronic pelvic pain Pelvic organ prolapse Pregnancy related conditions. Malignant diseases Cervical intraepithelial neoplasia Invasive cervical cancer Atypical endometrial hyperplasia Endometrial cancer Ovarian cancer Fallopian tube cancer Gestational trophoblastic neoplasia. Routes of Hysterectomy procedure is most often used in cases of uterine prolapse, or when vaginal repairs are necessary for related conditions. In a robot-assisted laparoscopic hysterectomy, the surgeon inserts the laparoscope and other instruments, then uses a computer station to control the instruments. Steps of Abdominal Hysterectomy There are different surgical techniques used to perform a hysterectomy. The uterus can be removed via the abdominal route, transvaginally, or laparoscopically. The uterus is removed through the abdomen via a surgical incision about six to eight inches long. The incision can be made either vertically, from the umbilicus to the pubic bone, or transversely, along the top of the pubic hairline. The vagina and perineum are cleaned with antiseptic solutions and a Foley catheter is inserted. The abdomen then is dressed with antiseptic solution from the anterior thighs to the xiphoid, and sterile drapes are applied. After confirming the pathology, the patient is put in a slight Trendelenburg position, a self-retaining retractor is placed, and the bowel packed superiorly to afford good exposure of the pelvis. Straight clamps are placed alongside the uterus near cornu (include the round ligament, fallopian tube and utero-ovarian ligaments. Round ligament transection: the right round ligament is visualised and clamped and divided and tied. Ovarian conservation: the fallopian tube and utero-ovarian ligament are doubly clamped and divided and doubly ligated. The infundibulopelvic ligament is doubly clamped, and the ovarian vessels are cut between the clamps. The proximal pedicle is ligated with a free tie followed by a transfixion suture ligature. Bladder flap: the peritoneal incisions from one round ligament to other are connected from the broad ligament over the bladder at the point of the vesicouterine reflection. The loose connective tissue is pushed down from the bladder to expose the endopelvic fascia over the anterior portion of the cervix. Uterine arteries: Next, the uterine arteries are identified along the lateral aspects of the uterus at the level of the isthmus. A Kocher (or equivalent) clamp is placed on the side of the cervix at approximately at 45° angle at the position of the uterine artery. Cardinal ligament transection: these ligaments lie lateral to the uterus and are inferior to the uterine vessels. A straight clamp is used to clamp the cardinal ligament A scalpel is used to transect the portion of the cardinal ligament held between the clamp. Uterosacral ligament transection: At this point, attention is directed to the posterior aspect of the uterus and to the uterosacral ligaments. The ligament is divided medial to the clamp, a transfixing suture is placed, and the clamp is removed. Vaginal entry: the vagina is incised and curved clamps are used to grasp the anterior and posterior vaginal walls at the point just below the cervix. Vaginal vault closure: the vaginal vault is sutured, either using figure of eight sutures or as a continuous running suture with careful attention to each angle. The pelvic peritoneum should be included in the suturing of the vagina to aid hemostasis. The pelvis is inspected for hemostasis: Reperitonealisation is not necessary, but may aid hemostasis. Steps of Vaginal Hysterectomy the patient is put under general or regional anesthesia. Vaginal wall incision: the cervix and vaginal mucosa may be injected with 10­ 15 mL of a dilute saline solution containing vasopressin (20 units diluted in 20 mL of saline) or 0. Injection of vasocontrictors decreases bleeding during dissection and aids in defining tissue planes. To avoid dissection into the cervix, this incision is kept at a depth superficial to the pubocervical fascia. Anterior peritoneal entry: the bladder is dissected off the anterior aspect of the uterus and displaced anteriorly. The Major Operations in Gynecology 361 vesicouterine fold is grasped and elevated to place this peritoneal layer on tension. Posterior entry: the posterior lip of cervix is lifted anteriorly to expose the posterior vaginal vault, and an Allis forceps is placed on the incised edge of the posterior vaginal wall. The Allis tissue forceps is pulled downward to create tension across the exposed posterior peritoneum. The posterior vaginal vault is cut with curved Mayo scissors, and the Douglas cul-de-sac is entered. Curved Kocher clamps are inserted into the pouch of Douglas to take the uterosacral pedicles first vertically angled and then horizontally. The uterosacral ligament is then transected, and ligated with 0-gauge delayed-absorbable suture using a transfixing stitch. After ligation of the uterosacral ligaments, the cardinal ligaments similarly are clamped, cut, and sutured. Clamps are, then, placed across the uteroovarian and round ligaments and fallopian tubes. The peritoneum is then closed in a purse string to include the uterine vessels and uterosacral pedicles and pouch of Douglas peritoneum. Postoperative management of hysterectomy patient: the details of postoperative care are dictated by the indications for hysterectomy, route of hysterectomy, i. Following vaginal hysterectomy, there is faster return of normal bowel function, easier ambulation, and decreased analgesia requirements in comparison to abdominal hysterectomy. The choice will vary from surgeon to surgeon but usually includes pethidine hydrochloride or meperidine sulfate. Once the patient can tolerate a regular diet, she can be switched to oral analgesics. The diet is advanced based on return of bowel sounds and appetite, toleration of the diet, and the passage of flatus. Complications of Hysterectomy Hysterectomy is one of the safe surgical procedures. But as with any surgery complication may occur: Peroperative complications: Injury to the bowel, bladder, ureter or major vessels. Excessive bleeding, complications due to anesthesia Early postoperative complications: Postoperative hemorrhage usually from the angle of vault of vagina, wound infection and febrile morbidity, pelvic hematoma and abscess formation, deep vein thrombosis, wound complications. Indications Myomectomy is indicated for women with symptomatic leiomyoma who are willing for fertility or willing to retain uterus. Following are the situations where myomectomy is indicated: Infertility with distortion of endometrial cavity or tubal occlusion Recurrent pregnancy loss with distortion of endometrial cavity Abnormal uterine bleeding not responding to medical treatment Pain and pressure symptoms that interfere with quality of life Urinary symptoms (frequency and/or symptoms of obstruction) Iron deficiency anemia secondary to menstrual blood loss.

Typically skin care tips in urdu buy decadron 0.5 mg lowest price, the vascular tortuosity is predominantly located at the macular and peripapillary area and develops during childhood or early adulthood acne gone proven decadron 8 mg. Although the disease may be asymptomatic, most patients complain of variable degrees of transient vision loss due to retinal haemorrhage following physical exertion or minor trauma. Involvement of non-ocular vascular beds has not been demonstrated in most cases but occasionally other associated vascular abnormalities have been recorded, including malformations in the Kieselbach nasal septum, spinal cord vascular mass, telangiectasis of bulbar conjunctiva and internal carotid artery aneurysm [123]. Patients present kidney alterations consisting of multiple renal cysts and sometimes haematuria. The brain is only mildly affected and intracranial aneurysms causing haemorrhagic stroke can occur. Leukoencephalopathy is found in about half of affected individuals whereas muscle cramps are experienced by most of patients in early childhood. In addition, patients may manifest eye problems, like arterial retinal tortuosity, cataract and abnormality called Axenfeld-Rieger anomaly [124]. Stroke is often the first symptom and is usually caused by haemorrhagic rather than ischemic stroke. Patients also have leukoencephalopathy and may experience infantile hemiparesis, seizures and migraine headaches accompanied by visual auras [125]. It is a neurological disorder characterized by fluid-filled cysts or cavities in the brain and is thought to result from disturbed vascular supply leading to cerebral degeneration. Affected individuals have delayed growth and development, hypotonia, spastic hemiplegia, seizures, migraine headaches, speech problems and intellectual disability with variable severity [126]. Schizencephaly is a very rare cortical malformation that results in grey matter line clefts impacting one or both sides of the brain. Two types of schizencephaly have been described, depending on the size of the area involved and on the separation of the cleft lips. The clinical picture is mainly based on the presence of motor deficits and mental retardation but the severity of the symptoms varies depending on the size and location of the clefts and on the presence of associated cerebral malformations. Patients with type I are almost normal, they may have seizures or motor impairment. The mutated vascular collagen diminishes the tensile strength of vessels and increases their fragility, which can lead to haemorrhage [128]. The severe bilateral sensorineural hearing loss apparent in infancy affects only males, who present bilateral malformation of the cochlea with incomplete separation from the internal auditory canal. Female patients develop mild to moderate hearing impairment in the third/fourth decades of life and rarely hearing loss in the first decade of life [129]. Diffuse attenuation of the glomerular basement membrane is usually considered the hallmark of the condition but it is not specific [130]. The disease is characterized by progressive muscle weakness and joint stiffness (contractures). The features can appear at any age, in some cases before birth (decreased foetal movements) in other cases during infancy with joint laxity (loose joints) and hypotonia (weak muscle tone). Later, during childhood, patients develop contractures in their fingers, wrists, elbows and ankles. When adult, they may develop weakness in respiratory muscles, which result in breathing difficulty. The mild form may also reveal skin abnormalities, including follicular hyperkeratosis on the arms and legs; soft, velvety skin on the hand palms and feet soles; abnormal wound healing resulting in shallow scars [131]. The disease is transmitted in an autosomal recessive manner and only in rare cases in a dominant pattern. Some affected individuals are never able to walk and others can walk only with support. Progressive scoliosis and deterioration of respiratory function is a typical feature. Affected individuals develop contractures in their neck, hips and knees, which further impair movement. There may be joint laxity in patient fingers, wrists, toes, ankles and other joints. The disorder is characterized by chronic inflammation of skeletal muscle with hyperplasia of the interstitial connective tissue. The clinical symptoms include slender muscles with "woody" consistency and restriction of movement of many joints because of muscle contractures. The few patients so far described showed difficulty in running and climbing stairs and had Achilles tendon contractures during early childhood. Skeletal muscle biopsies showed a myopathic pattern with fibrosis, proliferation of endomysial and perimysial connective tissue, variation of myofibre diameter. Neurological disorder characterized by the onset of segmental isolated dystonia involving the face, neck, bulbar muscles and upper limbs in the first two decades of life. Microscopic examination of the skin shows cleavage below the basement membrane within the papillary dermis. Severe cases involve widespread blistering leading to vision loss, disfigurement and other serious medical problems such as strictures of the gastrointestinal tract leading to poor nutrition. The nail plates of the toes were buried in the nail bed and the free edge of the toenail was deformed and narrow [137]. Corneal endothelial cells continue to die over time, resulting in further vision problems. As the endothelial layer develops confluent guttae in the central cornea, the cornea becomes dehydrated and clear [138]. The patients show a bilateral penetrating keratoplasty at the age of twenties (daughter) and fifties (father). Both cartilage and bone development are affected, mainly at the ends of the long bones in the arms and legs (epiphyses). A 30-year-old proband was reported with knee pains and difficulty walking since 10 years of age. Radiographs showed early osteoarthritis of one knee, Schmorl nodes, endplate irregularities, anterior osteophytes in the thoracolumbar vertebrae and normal hips. Radiographic features include widening and irregularity of the growth plates, especially in the distal and proximal femora. Patients have a distinctive flat midface with a flattened nasal bridge (saddle nose), nostrils that turn upward, widely spaced eyes, high myopia, cataracts and sensorineural hearing loss. Other symptoms include crossed eyes (esotropia), retinal detachment, glaucoma, protruding upper incisors (teeth) and a small or missing nasal bone [145]. The disorder is named for the disorganized cartilage growth plate in which chondrocytes have a fibroblastic appearance and the presence of fibrous cartilage extracellular matrix. Patients are characterized by short stature (dwarfism) and skeletal abnormalities. Affected individuals have shortened long bones in the arms and legs that are unusually wide at the ends (described as dumbbell-shaped). Vertebrae are flattened (platyspondyly) and have a characteristic pinched or pear shape that is noticeable on x-rays. Affected infants have a very narrow chest, which prevents the lungs from developing normally. Affected individuals who survive the neonatal period have high myopia, mild to moderate hearing loss and severe skeletal dysplasia [146]. A single family has been described, characterized by a dominant nonsyndromic postlingual hearing loss. The affected individuals experienced progressive hearing loss beginning in the second to fourth decades [147]. The term "otospondylomegaepiphyseal" refers to the parts of the body that are affected: ears (oto-), bones of the spine (spondylo-) and the ends (epiphyses) of long bones in the arms and legs. The disorder is characterized by sensorineural hearing loss, relatively short extremities with abnormally large knees and elbows (enlarged epiphyses), vertebral body anomalies and characteristic facies. The diagnostic radiologic findings are enlarged epiphyses combined with moderate platyspondyly, mainly in the lower thoracic region. Patients present hypotonia, feeding difficulties and respiratory problems soon after birth. Erosions often are precipitated by relatively minor trauma and are often difficult to treat, lasting for up to a week. Fortunately, the erosions become less frequent as patients age and may cease altogether by the fifth decade of life. The onset is in the first decade of life (even in the first year of life) often with some subepithelial haze or blebs while denser centrally located opacities develop with time. Small grey anterior stromal flecks associated with larger focal grey-white disc-shaped, circular or wreath-like lesions with central clarity, in the Bowman layer and immediately subjacent anterior stroma, varying from 0. Eye abnormalities include high myopia, cataracts, dislocated lens, vitreoretinal degeneration and retinal detachment. The patients had variable abnormal ocular motility without other systemic defects. Two sibs showed congenital ptosis with levator palpebrae muscle dysinnervation of one or both orbits. The third sib had no ptosis but showed bilateral Duane retraction syndrome, exotropic in the right eye and esotropic in the left [152]. Hereditary disorders associated to reduced synthesis or excessive degradation of specific collagen types. After birth, extensive blisters may affect the mucous membranes particularly the oral cavity, oesophagus and anal canal. Caused by chronic blood loss, inflammation, infection and poor nutrition, patients develop anaemia, failure to thrive, delayed puberty and osteoporosis. Patients usually do not survive more than 30 years due to severe renal complications or aggressive squamous cell carcinoma arising in the areas of repeated scarring [154]. The main symptoms of this condition are dysphasia, frontotemporal cerebral atrophy and frontotemporal dementia, speech disorder, memory impairment [155]. Common additional clinical features include collodion baby, characteristic facies, ocular abnormalities, short stature, decreased fertility and recurrent infections. The onset of disease is typically observed during the first two years of life [161]. The hallmarks of atopic dermatitis are a chronic relapsing form of skin inflammation, a disturbance of epidermal barrier function that culminates in dry skin and IgE-mediated sensitization to food and environmental allergens. Most cases had normal teeth, white sclera, normal cognitive functions and normal hearing. A few cases had dysmorphic features including triangular face and brachycephaly [162]. This hydroxylation is essential for the stability of intermolecular collagen crosslinks. Mutations in this gene affect the instalment and secretion of collagen fibres from osteoblasts [163]. General features also include congenital muscle hypotonia, congenital or early onset kyphoscoliosis, joint hypermobility with subluxations or dislocations of shoulders, hips and knees [164]. Blue sclerae, micrognathia, umbilical hernia and postnatal growth retardation are reported [164]. Hyperelasticity of the skin without excessive fragility and hypermobility of the joints are other hallmarks of the disease [164]. Systemic abnormalities included increased skin laxity, pectus excavatum, scoliosis, congenital hip dislocation, recurrent shoulder dislocation, high-frequency hearing loss, high-arched palate and mitral valve prolapse [166]. Systemic manifestations are mild whereas pulmonary emphysema and cardiac anomalies are rare. In some case, additional features have been described, including delayed development, intellectual disability, seizures and problems with movement that can worsen over time. Patients also exhibit a combination of muscular hypotonia with brisk muscle reflexes [170]. It is a bilateral, often asymmetrical, non-inflammatory progressive corneal ectasia that causes visual morbidity. In affected individuals, the cornea becomes progressively thin and conical in shape, resulting in myopia, irregular astigmatism and corneal scarring. It typically appears in the teenage years and then it progresses until the third and fourth decades. No specific treatment exists except corneal transplantation when visual acuity can no longer be corrected by contact lenses [172]. Abbreviations: the acronyms of the pathologies are all specified inside the Table. Conclusions the large number of genetic disorders associated to collagen alterations clearly strengthens the relevance of this wide group of proteins, which have been for long time considered inert elements with no other function than maintenance of tissue shape and architecture. The observation that mutations in collagen coding genes result in alterations of relevant developmental processes (skeletal and cartilage development) or defects of tissue homeostasis (skin, sensorineural, visual and muscle alterations) clearly demonstrate a regulatory role for this type of molecules.
