Aetiology and classification of pericardial disease the spectrum of pericardial diseases comprises congenital defects serum cholesterol chart generic atorvastatin 40mg with mastercard, pericarditis (dry cholesterol in shrimp order atorvastatin without prescription, effusive low cholesterol eggs in india generic 20mg atorvastatin free shipping, effusive-constrictive, constrictive), neoplasm, and cysts. However, homolateral cardiac displacement and augmented heart mobility impose an increased risk for traumatic aortic type A dissection. Major symptoms are retrosternal or left precordial chest pain (radiates to the trapezius ridge, can be pleuritic or simulate ischaemia, and varies with posture), non-productive cough, and shortness of breath. Indications for various tests and procedures were ranked in three classes: Class I: Conditions for which there is evidence and/or general agreement that a given procedure or treatment is useful and effective. Percentage related to the population of 260 subsequent patients undergoing pericardiocentesis, pericardioscopy and epicardial biopsy (Marburg pericarditis registry 19882001). Systemic corticosteroid therapy should be restricted to connective tissue diseases, autoreactive or uremic peri- carditis. If patients require anticoagulants, heparin is recommended under strict observation. Pericardiocentesis is indicated for clinical tamponade, high suspicion of purulent or neoplastic pericarditis (class I indication, level of evidence B), or for large or symptomatic effusions despite the medical treatment for more than one week 9;2637 (Focus box 1). Focus box 1 Pericardiocentesis Pericardiocentesis is life saving in cardiac tamponade (level of evidence B, class I indication). Pericardiocentesis in acute traumatic haemopericardium and purulent pericarditis is probably less appropriate than surgical drainage. The subxiphoid approach has been used most commonly, with a long needle with a mandrel (Tuohy or thin-walled 18-gauge) directed towards the left shoulder at a 30° angle to the skin. This route is extrapleural and avoids the coronary, pericardial, and internal mammary arteries. The operator intermittently attempts to aspirate fluid and injects small amounts of contrast. If haemorrhagic fluid is freely aspirated a few millilitres of contrast medium may be injected under fluoroscopic observation. The appearance of sluggish layering of contrast medium inferiorly indicates that the needle is correctly positioned. It is prudent to drain the fluid in steps of less than 1 l at a time to avoid the acute right-ventricular dilatation ("sudden decompression syndrome"). If the guidewire was erroneously placed intracardially, this should be recognized before insertion of the dilator and drainage catheter. If, despite the caution, the introducer set or the catheter have perforated the heart and are laying intracardially, the catheter should be secured and the patient promptly transferred to the cardiac surgery. Echocardiographic guidance of pericardiocentesis is technically less demanding and can be performed in the intensive care unit at the bedside. Prolonged pericardial drainage is performed until the volume of effusion obtained by intermittent pericardial aspiration (every 46 h) fall to <25 ml per day. Pericardiocentesis with echocardiography guidance was feasible in 96% of loculated pericardial effusions after cardiac surgery. In addition, patients can experience air embolism, pneumothorax, arrhythmias (usually vasovagal bradycardia), and puncture of the peritoneal cavity or abdominal viscera. Recent large echocardiographic series reported an incidence of major complications of 1. Incidence of major complications was further significantly reduced by utilizing the epicardial halo phenomenon for fluoroscopic guidance. Symptoms are usually mild (chest pain, palpitations, fatigue), related to the degree of chronic cardiac compression and residual pericardial inflammation. Intrapericardial instillation of crystalloid nonabsorbable corticosteroids is highly efficient in autoreactive forms. Evidence for an immunopathological process includes: (1) the latent period lasting for months; (2) the presence of anti-heart antibodies; (3) the quick response to steroid treatment and the similarity and co-existence of recurrent pericarditis with other autoimmune conditions (lupus, serum sickness, polyserositis, postpericardiotomy/postmyocardial infarction syndrome, celiac disease, dermatitis herpetiformis, frequent arthralgias, eosinophilia, allergic drug reaction, and history of allergy). Evidence of a potential underlying genetic disorder in recurrent pericarditis is rare familial clustering with autosomal dominant inheritance with incomplete penetrance39 and sex-linked inheritance (chronic recurrent pericarditis associated with ocular hypertension) suggested in two families.

The number of taxa recovered from red-palm weevils and honey bees was almost equal, while lower number was isolated from beetles. However, a higher number of yeast species was obtained from the gut of red-palm weevils than those obtained from honey bees or black beetles. Some filamentous species were recovered from the guts of the three insect species (Aspergillus niger, A. However, none of yeast species was regularly recovered from the three insect guts, but two insect species may share the same yeast species in their guts. To our knowledge, some of the isolated yeast species are being reported here for the first time from insect guts.
The germ cells will be the future oogonia and the epithelial cells will be the future granulosa cells cholesterol levels us and canada 10 mg atorvastatin for sale. From 20th week cholesterol joint pain purchase atorvastatin with visa, the oocytes that are not surrounded by the granulosa cell envelope high blood pressure & cholesterol lowering foods buy discount atorvastatin 5mg online, are destroyed. The stromal mesenchymal cells also surround the follicular structure to form the future theca cells. By 28th week, number of these follicles are exposed to maternal gonadotropin and undergo various degrees of maturation (little short of antrum formation) and atresia. Descent of the Ovary the cranial part of the genital ridge becomes the infundibulopelvic ligament (Fig. From the lower pole of the ovary, genital ligament (gubernaculum) the surface becomes thicker and continues to proliferate extensively. It sends down secondary 40 textbook of GyneColoGy the Mьllerian attachment is the ovarian ligament and the part between the cornu of the uterus to the end is the round ligament. The ovaries descend during the seventh to ninth months, and at birth, they are situated at the pelvic brim. The genital ligament gets an intermediate attachment as it comes close to Mьllerian ducts (angle of the developing uterus). Clitoris is developed from the genital tubercle, labia minora from the genital folds and labia majora from the genital swellings. The cortex and the covering epithelium are developed from the coelomic epithelium and the medulla from the mesenchyme. The germ cells are endodermal in origin and migrate from the yolk sac to the genital ridge. The bipotential gonad develops into an ovary about two weeks later than the testicular development. The part of the gubernaculum (genital ligament) between the lower pole of the ovary and the Mьllerian attachment is the ovarian ligament. The part between the cornu of the uterus (Mьllerian attachment) to the end (external genitalia) is the round ligament. The ovaries descend during seventh to ninth months, and at birth, they are situated at the pelvic brim. The paramesonephric duct in female differentiates into fallopian tube, uterus and cervix. The mesonephric duct in male gives rise to epididymis, vas deferens and seminal vesicles. The sinovaginal bulbs, which grow out from the posterior aspect of the urogenital sinus, differentiates into vagina. Urinary bladder develops from the upper vesicourethral part of the urogenital sinus except the trigone. Developmental anomalies of the external genitalia along with ambiguity of sex are usually genetic in origin Major anatomic defect of the genital tract is usually associated with urinary tract abnormality (40%), skeletal malformation (12%), and normal gonadal function While minor abnormality escapes attention, it is the moderate or severe form, which will produce gynecologic and obstetric problem. Partial nephrectomy and ureterectomy may be indicated or implantation of the ectopic ureter into the bladder may be done. Dyspareunia may be the first complaint, or it may be detected during investigation of infertility. The anal opening is situated either close to the posterior end of the vestibule or in the vestibule. If there are features of obstruction or the opening is situated high in the vagina, pull through operation is to be done bringing the anal end to the anal pit with prior colostomy. It is due to failure of disintegration of the central cells of the Mьllerian eminence that projects into the urogenital sinus (see p. The existence is almost always unnoticed until the girl attains the age of 1416 years. As the uterus is functioning normally, the menstrual blood is pent up inside the vagina behind the hymen (cryptomenorrhea).
Microscopic diagnostic features are: presence of endometrial glands definition du cholesterol total atorvastatin 5 mg discount, stroma and hemosiderin-laden macrophages cholesterol levels standard 40 mg atorvastatin visa. It is progressive in about 3060 percent patients and for the remainder it is either static or resolve spontaneously list of best cholesterol lowering foods order 40 mg atorvastatin fast delivery. However, the association of minimal to mild endometriosis and infertility is controversial. Other complications of endometriosis are: Acute abdomen due to rupture of chocolate cyst, infection of the cyst, colorectal obstruction and ureteral obstruction. Expectant treatment is extended to unmarried or young married with no abnormal pelvic findings. The mechanism of atrophy can be explained by pseudopregnancy or by pseudomenopause or by medical hypophysectomy (see p. Conservative surgery in endometriosis includes removal of all macroscopic endometriosis, lysis of adhesions and restoration of normal pelvic anatomy. Endoscopic laser surgery is the best in selected cases for the treatment of pain and to prevent the disease progress. Large ovarian endometrioma (> 3 cm) is treated by laparoscopic ovarian cystectomy. Postoperative medical treatment should not prevent pregnancy as the chance of pregnancy is highest during the first 612 months after the conservative surgery. Definitive surgery includes total hysterectomy with bilateral salpingo-oophorectomy. Laparotomy is done for advanced stage disease or in women who has completed her family. Postoperative estrogen replacement therapy after total hysterectomy and bilateral oophorectomy may be given 3 months after surgery. Regression frequently occurs in young woman, during pregnancy or when it is caused by viral infection. The following facts are to be borne in mind: It is more frequent in patients in the age group 2040 years, i. Local examination reveals a lesion in the vulva with white, grey, pink or dull red color. To exclude vaginal or cervical neoplasia, cytologic evaluation has to be performed. There is hyperkeratosis, acanthosis (hyperplasia of epidermis) and chronic inflammatory cell infiltration. Topical fluorinated steroid ointment can be applied twice daily for a period of about 6 months. Surgery: the following are the types of surgery: Local excision-Wide local excision with 1 cm margin is reserved in young patient with localized lesion. Simple vulvectomy-It is employed in diffuse type especially in postmenopausal women (see p. Associated adenocarcinoma of apocrine gland (adenocarcinoma in situ) is present in about 10 percent of the cases. Local examination reveals-labia majora appear red, scaling, with elevated lesion. Multiple biopsies are to be taken to exclude associated adenocarcinoma of the apocrine glands. If it is found positive, bilateral lymph node dissection should be done at a second stage. The grading is done according to the thickness occupied by the undifferentiated cells. However, there is considerable degree of overlapping regarding the precise definition of fig. The prolonged effect of carcinogens can produce continuous changes in the immature cells which may lead to malignancy. Early age sexual activity and multiple sexual partners are the most consistent risk factors. Thus, it is apparent that some of these epithelial atypia either remain stationary, regress or even progress to invasive carcinoma. Two mechanisms are involved in the process of replacement of endocervical columnar epithelium by squamous epithelium.
Complex endometrial hyperplasia with atypia: Besides the above mentioned changes associated with complex endometrial hyperplasia food cholesterol chart uk buy atorvastatin online, epithelium also shows atypia (hyperchromatism cholesterol medication lovastatin order cheap atorvastatin line, mitotic figures cholesterol ratio explained order atorvastatin 5mg amex, etc). Patients with a history of unopposed estrogen exposure should be first evaluated by transvaginal ultrasound examination. Simple endometrial hyperplasia can be corrected using cyclic progestin therapy with medroxyprogesterone acetate, 10 mg daily or norethistherone acetate 5 mg daily for 14 days. Women who respond to the medical treatment must be encouraged to have regular check-ups as recurrence of hyperplasia can commonly occur. Endometrial hyperplasia with atypia (especially atypical adenomatous hyperplasia) generally is considered equivalent to an intraepithelial malignancy and hysterectomy is usually advised. Any biopsy that reveals endometrial carcinoma requires a prompt immediate referral to a gynecologic oncologist. If no tissue is present on endometrial biopsy, the endometrium is most probably atrophic and requires treatment with estrogens. The distance from the fundus to the external cervical os can be measured with the help of gradations on the uterine sound and is usually equal to 6 to 8 cm. This helps in assessing the position and size of the uterine cavity and minimizing the risk of perforation. When the position and size of the uterine cavity have been assessed, the endometrial biopsy curette (figure 17. The endometrial biopsy curette is a narrow metal cannula having serrated edges with side openings on one end and syringe attached for suction at the other end. While inside the uterine cavity, the cannula is rotated several times in order to scrape off the endometrial lining (figures 17. This procedure should be repeated at least four times and the device rotated by 360° to ensure adequate coverage of the area. When adequate amount of endometrial curetting have been obtained, the curette is removed and samples are sent for microscopic examination. Normal endometrial tissue may be described as proliferative or preovulatory (under the effect of hormone estrogen) and secretory or postovulatory endometrium (under the effect of hormone progesterone). Hormone therapy can be offered to patients with abnormal vaginal bleeding who have normal endometrial tissue on biopsy. If the biopsy is normal but the patient continues to experience excessive vaginal bleeding, further diagnostic work-up is required. Abnormal pathology on histopathalogical examination must be treated as follows: · Most individuals with simple hyperplasia without any atypia can be managed with hormonal manipulation [medroxyprogesterone (Provera), 10 mg daily every five days for three months] or with close followup. Most authors recommend a follow-up endometrial biopsy after 3 to 12 months, regardless of the management strategy. Some physicians treat complex hyperplasia with or without atypia with hormonal therapy (medroxyprogesterone, 10 to 20 mg daily for up to three months). However most physicians recommend a D&C procedure to exclude the presence of endometrial carcinoma and consider hysterectomy for complex or high-grade hyperplasia. Endometrial biopsy should not be performed in the presence of a normal or ectopic pregnancy. All patients with the potential for pregnancy should be considered for pregnancy testing prior to the performance of the procedure. Bacteremia can occur after endometrial sampling (antibiotic prophylaxis must be given to patients at risk of endocarditis). Since post-procedure bacteremia has been noted, some authors recommend considering antibiotics in postmenopausal women at risk for endocarditis. Diagnosing the type of endometrial histopathology: Hyperplastic, proliferative, secretory, irregular ripening, irregular shedding, atrophic endometrium, etc. Not only does it help in detecting the site of malignancy but also gives an idea regarding the spread of malignancy. The sample obtained on D&C is larger than the one obtained by an endometrial biopsy.
