This operation has been successfully accomplished laparoscopically using the extraperitoneal route or the transperitoneal route show cholesterol chart cheap atorlip-20 online american express. The tape does not elevate the urethra, but provides a resistant platform in the midurethra that maintains continence against intra-abdominal pressure. This technique is good for obese women, as it does not causes detrusor dysfunction. After exposing the region of the bladder neck on vaginal dissection, the hammock of the tape is placed underneath it to provide support at the mid-urethral level, the lateral extensions are brought out paraurethrally onto the skin at the level of the pubic symphysis and the vaginal incision is closed. Instead, a hammock is inserted mid-urethra by passing the trocar from the thigh through obturator canal. Mid-urethral sling is good for urethral hypermobility, whereas other slings are for internal sphincter dysfunction. Glutaraldehyde crosslinked bovine collagen (Contigen, Bard) is commercially available for periurethral injection. It can be undertaken as an office procedure for mild cases, but is often reserved for cases of surgical failures. The procedure raises the urethral pressure by external compression and is useful in sphincteric dysfunction. Recently, micronized silicon rubber particles suspended in nonsilicon gel known as uroplasty has been used with success. The tape is placed under the mid-urethra, taken through the obturator membrane to be fixed to the thigh. Pathophysiology Increased alpha-adrenergic and cholinergic activity is responsible for this condition. Potential reasons for failure include: n Symptoms A woman develops involuntary escape of urine with urge to urinate. This urge is accompanied by frequency more than seven times during the day and at least once during the night. Incorrect choice of operation-mainly the result of incomplete or incorrect preoperative assessment of the cause of urinary incontinence. Investigations n n n With the passage of time, the results of all kinds of incontinence surgery tend to deteriorate. Urine culture will indicate if the urinary infection is the cause of frequency and urge. Other investigations may be required to rule out other causes of associated bladder neck instability. Detrusor hyperreflexia (neuropathy) in certain medical conditions such as diabetic neuropathy, a cerebrovascular Low caffeine and nonsmoking. Urispas (flavoxate) is a musculotropic and has a direct action on the smooth muscle, 200 mg t. Side effects include headache, nausea, constipation, dry mouth and blurred vision. Outflow obstruction, glaucoma, myasthenia gravis Sedation, constipation, blurred vision Less side effects Headache, nausea, dry mouth, blurred vision Decreased libido Under trial n Imipramine (tricyclic antidepressant) 50 to 100 mg at night for 3 months is 70% successful. A volume of 10 mL of 6% phenol injected into the trigone; 60% benefit for a short period but at the end of 1 year only 2% are relieved. Acupuncture may be useful in some cases, urethral dilatation is successful in a few cases when the drugs fail. It is a major surgery that requires self-catheterization and mucous secretion by ileal mucosa can be troublesome. Twenty-five per cent complain of other urinary problems and 5% develop adenocarcinoma of the ileal segment. Augmental cystoplasty requires self-catheterization, causes stone formation, urinary infection as well as electrolyte imbalance and malignancy. Side effects: Retention of urine and requires selfcatheterization, normally in the first 6 weeks. Though side effects of anticholinergic therapy are avoided, this technique has a higher rate of urinary retention and urinary infection. Restricting fluid intake, psychotherapy and treating the cause are also of importance. Bladder drilling or training disciplines the bladder to hold the urine for a longer period. It is contraindicated in coronary heart disease, hypertension and epilepsy in elderly women. Biofeedback uses visual and auditory signals to demonstrate the strength of detrusor activity. It comprises surgical implantation of a generator to provide stimulation to the sacral nerve. However, they still contribute a major share of all genital fistulae seen in clinical practice in India. Genital fistulae occur following prolonged unsupervised obstructed labour, following difficult vaginal instrumental deliveries, and occasionally as a complication of caesarean section. Investigations including methylene blue dye test, descending pyelography, cystoscopy and ureteric catheterization may be required to settle the diagnosis.

Russian surgeon at St Petersburg, a pioneer of battlefield trauma surgery, also known for introducing rectal diethyl ether for surgery in 1847. Also studied the effects of ether, designed apparatus for its rectal and inhalational administration, and published the first book on the subject in 1847. Rapidly absorbed after oral administration, it is 99% protein-bound and has a long (50 h) half-life; thus can be given once daily. Lies in the pituitary fossa of the sphenoid bone, above the sphenoid air sinuses and below the optic chiasm. Composed of anterior and posterior lobes, connected to the hypothalamus by the infundibular stalk, which contains nerve fibres and the hypophyseal portal blood system. The infundibulum pierces the diaphragma sellae, a dural sheet, that covers the gland. Function: anterior lobe: - contains cells formerly classified by their staining properties (chromophobe, eosinophil and acidophil cells); now identified on an immunocytochemical basis into five cell types: - somatotrophs: secrete growth hormone. Pituitary gland disease may be associated with over- or under-secretion of hormones (usually the latter). Negative logarithm (to base 10) of the dissociation constant for a weak acid or base in aqueous solution. Whilst pKa strictly refers to an acidic substance and pKb to a basic one, by convention pKa is used to refer to both acids and bases. The stronger an acid, the lower its pKa, and the stronger a base, the higher its pKa. Thus important when considering ionisation of drugs and passage of drugs or other substances across membranes. The endometrium is invaded by the outer layer of the trophoblast of the egg, the syncytiotrophoblast. Further proliferation of the trophoblast forms finger-shaped masses of tissue, the chorionic villi, between which spaces (lacunae) appear. The tips of the villi erode the walls of the endometrial spiral arteries so that the lacunae expand to form large spaces filled with maternal blood within which float the villi. Primitive blood vessels appear in the villi from about 18 days after fertilisation, eventually joining the fetal umbilical vessels. Densely packed masses of fetal villi (fetal cotyledons) are supplied by branches of the umbilical arteries, distributed radially as end-arteries. Thus the barrier between fetal and maternal circulations is two cells thick, consisting of the fetal capillary endothelium and its covering of syncytial trophoblast. Blood supply: fetal: blood arrives via two umbilical arteries and leaves by a single umbilical vein. Umbilical blood flow is up to 100 ml/min at 22 weeks and 300 ml/min at term, of which about 20% does not participate in exchange with maternal blood. There is no autoregulation in the placental circulation and therefore flow is directly related to mean uterine perfusion pressure and inversely related to uterine vascular resistance. Impaired function causes fetal hypoxaemia and acidosis if acute, and may lead to delayed fetal growth if chronic. More common in smokers, preeclampsia, multiparity, abdominal trauma, and those with a previous history of placental abruption. Problems: a cause of antepartum haemorrhage; presents with abdominal pain and, usually, fetal distress. The amount of vaginal bleeding (if present) may underestimate the extent of haemorrhage, which may be visible on ultrasound as retroplacental clot. Anaesthetic management: standard techniques as for obstetric analgesia and anaesthesia. Coagulation studies are mandatory before regional anaesthesia is performed, if chosen. Problems: may cause antepartum haemorrhage with cardiovascular collapse and fetal distress. Anaesthetic management: standard techniques, as for obstetric analgesia and anaesthesia.

The attempted formation of a rudimentary eye has been described and even the recognizable pattern of a fetus has been simulated, the so-called embryoma. As a rule, however, the formation is a conglomerate, without order or arrangement. Most solid teratomas of the ovary are malignant tumours because of sarcomatous change, but about 20% are innocent (Figure 33. It usually arises in young women or in children, with an average incidence at the age of 20. The tumour is solid with a peculiar elastic rubbery consistency and a smooth, firm capsule. It is usually unilateral, bilateral in 10%, occasionally undergoes torsion and may, like all solid tumours, be associated with ascites. This appearance of large dark-staining nuclei with clear, almost translucent, cytoplasm and lymphocytic infiltration of the fibrous septa is diagnostic (Figure 33. A number of patients with a dysgerminoma of the ovary have been reported to show genital abnormality, with hypoplasia or absence of some part of the genital tract. Such congenital abnormalities are not caused by the dysgerminoma and its removal has no beneficial effect upon them. The presence of extra pelvic metastases in the general peritoneal cavity, lymph glands, omentum or liver renders the outlook hopeless. S consisting almost entirely of thyroid tissue and should be clearly distinguished from a dermoid cyst with thyroid tissue in its wall. To the naked eye, the tumour resembles a small mucinous cystadenoma, but the material contained in the vesicles is colloid and gives reaction to iodine. Most of the tumours are innocent, but malignant thyroid tumours have been recorded. The histogenesis is supposedly a dermoid in which the thyroid tissue dominates at the expense of the other elements. Carcinoid Tumours An interesting tumour of the ovary, sometimes primary and sometimes metastatic, is the argentaffinoma. It occurs as a malignant change in a benign dermoid cyst and presents as a solid yellow tumour with the histological property of reducing silver salts derived from the specialized Kulchitsky cells of the intestine. Though highly radiosensitive, ovarian destruction contraindicates the use of radiotherapy in young girls. Gonadoblastoma contains calcified elements, and Y chromosome is detected in 90% tumours. When occurring in adult life, the oestrogenic effect is less marked than in the prepubertal stage. There is no change in the secondary sexual characteristics since these are already established. Superthreshold level of blood oestrogen may lead to amenorrhoea, followed by prolonged bleeding. In fact, the behaviour of the endometrium closely resembles that of metropathia haemorrhagica. In the post-menopausal patient, the most remarkable feature is post-menopausal bleeding (Figure 33. The secondary sexual characteristics are less affected though hypertrophy of the breast is sometimes seen. The uterus shows myohyperplasia and cystic glandular hyperplasia exactly as in metropathia. Macroscopic Features the tumour varies in size from tiny to gross, the average being 10 cm in diameter. The cut surface is reticular or trabeculated with areas of interstitial haemorrhage, and shows yellow areas. The cells are arranged either in cords or in trabeculae, and are often surrounded by structureless hyaline tissue, which resembles the glass membrane of an atretic follicle. These small cyst-like spaces are Sex Cord Stromal Tumours Sex cord stromal tumours originate either from the sex cords of the embryonic gonad (before the differentiation of the gonadal mesenchyme into male or female) or from the stroma of the ovary. Since theca cells are the source of ovarian steroids, many of these are functional and exert feminizing effects. The embryonic sex cords may differentiate along the male line, giving rise to Sertoli or Leydig cell tumours called androblastomas. Feminizing Functioning Mesenchymoma Granulosa Cell Tumour Granulosa cell tumours are interesting growths of the ovary composed of cells closely resembling the granulosa cells of the Graafian follicle. Clinical Features Granulosa cell tumours are fairly common and represent 10% of all solid ovarian tumours. The tumour is observed in 80% of women over 40 years and in 5% of prepubertal girls. The main clinical features depend upon the oestrogenic activity of the tumour and only the larger ones cause pain and abdominal swelling.
Tuberculous lesions can be seen on the parietal peritoneum cholesterol lowering foods diet plan order 20 mg atorlip-20 fast delivery, intestinal serosa cholesterol medication bruising proven atorlip-20 20mg, omentum worst high cholesterol foods cheap atorlip-20 20mg free shipping, surface of the uterus and fallopian tubes (thickened rigid tubes/hydrosalpinx cholesterol levels peanut butter order atorlip-20 australia, pyosalpinx, tubo-ovarian adnexal masses. Tissue biopsy: Local excision tissue biopsies from suspected lesions from the lower genital tract (vulva and vagina) submitted for histology help to establish the diagnosis. Gas chromatography: Direct demonstration of compounds characteristic of mycobacteria shows great promise (90% sensitive) to provide rapid diagnosis. Biochemical markers: Ascitic fluid is tested for presence of markers such as adenosine and deaminase activity. Ovarian cyst, broad ligament cyst, encysted fluid: these cysts are fixed and immobile. However, the menstrual history is usually normal unlike in women with tubercular encysted lesion. Any history of previous extragenital tuberculosis goes in favour of genital tuberculosis. However, history of frequent recurrences of failure of response to treatment should raise the suspicion of genital tuberculosis. Ectopic pregnancy: History of delayed menses, abdominal pain and presence of a unilateral adnexal mass should raise the suspicion of ectopic pregnancy. Urine pregnancy test, Transvaginal sonography with colour Doppler blood flow studies and diagnostic laparoscopy should help in the management of the case. Carcinoma cervix: In women presenting with local cervical lesions (ulcer, polypoidal growth) clinical findings such as lack of induration, lack of friability should raise suspicion of alternative pathology. Elephantiasis of the vulva: Filariasis of the vulva can mimic hypertrophic tuberculosis of the vulva. Puberty menorrhagia and postmenopausal bleeding due to other causes need to be excluded. Fungal infections and sarcoidosis cause granulomatous lesions-histologically resembling tubercular granulomas. This short course gives quick and successful results, prevents emergence of drug-resistant bacilli. Ethambutol should not be administered for a longer period as it may affect the vision (optic neuritis) and cause skin rash. The oral contraceptives are not effective in the presence of rifampicin, as the latter interferes with their absorption. Only those who have fever and abdominal pain are admitted to the hospital in the initial stages of the treatment. It covered 87% population with 72% detection rate and 86% treatment success, with a sevenfold decline death rate from 29% to 4%. First 2 months n n n n Chemotherapy the first line of treatment is with antitubercular drugs (Table 14. Capreomycin Kanamycin Ethionamide para-Aminosalicylic acid Cycloserine Next 4 months-continue with Rifampicin and Isoniazid (same dose) three times a week. Resistant Cases (8 months course) First 2 months-streptomycin three times a week 1 4 doses as above Third month-4 drugs as above Next 3 months-Isoniazid, rifampicin, ethambutol (same dose) three times a week. In Vitro Fertilization Women successfully treated for genital tuberculosis are now offered assisted reproduction by in vitro fertilization. Key Points Surgery Indications of surgery are progression of the disease, persistent active lesion, persistence of large inflammatory masses, i. Contraindications to surgery are active lesions elsewhere in the body and plastic adhesions of bowels. Surgery should be preceded by several weeks of chemotherapy, followed by a full course of chemotherapy. Types of surgery n n n n n n n n n n Total hysterectomy with removal of ovaries and the fallopian tubes. Any surgery on the tube to improve fertility would cause reactivation of the disease. A yearly or when indicated earlier curettage should be carried out to check for any reactivation. Hysterosalpingogram is however not advisable, as it may reactivate the dormant infection. Surgery may be required if the disease persists and does not respond to drugs, and the treatment is hysterectomy and bilateral salpingo-oophorectomy, and removal of tubo-ovarian mass in a young woman. Pregnancy rate following treatment is only 10%, of which one-third abort and another 50% develop ectopic pregnancy. High degree of suspicion is required in an asymptomatic woman, especially in an infertile woman. They need to be recognized and repaired immediately to avoid bleeding, infection, painful scar and symptoms related to the associated injury to the neighbouring structure. Obstetric Injuries Most injuries of the female genital tract occur during childbirth. In a normal delivery, the circular fibres which surround the external cervical os are torn laterally on each side so that an anterior and a posterior lip of the cervix become differentiated.
