What are the indications buy generic duetact 17 mg diabetes test canberra, conditions to be fulfilled buy 17mg duetact fast delivery managing diabetes genetics, and contraindications of myomectomy? Epithelial ovarian tumors (60–70%) Œ Serous cystadenoma Œ Mucinous cystadenoma Œ Endometrioid tumor B proven 200mg plaquenil. Germ cell tumors (20–25%) Œ Dysgerminoma Œ Mature teratoma (dermoid cyst) Œ Endodermal sinus cell tumor Œ Choriocarcinoma Œ Immature teratoma. Specimen shows solid nodular masses with areas of hemorrhage and necrosis 410 Bedside Clinics and Viva-Voce in Obstetrics and Gynecology Œ Sertoli-Leydig cell tumors Œ Fibroma. Epithelial ovarian tumors soften undergo malignant changes Œ Serous cyst adenocarcinoma Œ Mucinous cyst adenocarcinoma Œ Malignant endometrioid (rare). Common symptoms are: Abdominal distension and discomfort, dyspepsia, loss of appetite, dull aching lower abdominal pain, weight loss and respiratory distress due to ascites or pleural effusion. High-risk factors for ovarian malignancy a) Age: 40–60 years b) Familial cancers: Breast, endometrial and ovarian c) Postmenopausal palpable ovary (volume>8 cc) d) H/o infertility. Protective factors for ovarian malignancy are: a) Combined oral contraceptives b) Pregnancy c) Tubal ligation d) Salpingectomy e) Breastfeeding. What are the principles (guidelines) of surgical approach in a malignant ovarian tumor? A systematic exploration of the pelvic and abdominal cavity to detect metastasis and enlarged lymph nodes. Biopsy from any metastatic deposit or from the peritoneum when no metastasis is observed. Prophylactic oophorectomy during hysterectomy may be considered in women who are at high risk for ovarian malignancy Q. Early stage disease (stage Ia, G1, G2) Œ Young woman → unilateral oophorectomy (fertility conserving surgery) → routine follow up → once family completed → removal of uterus and other ovary. Advanced stage disease a) Cytoreductive surgery or debulking procedure b) Adjuvant chemotherapy. Clinical, biochemical (tumor markers) and biophysical (sonography including color Doppler) methods are commonly used. How can a benign ovarian tumor can be differentiated from a malignant one clinically? Benign ovarian tumor has the following clinical features: It is usually: a) Unilateral b) Mobile c) Cystic feel d) Smooth surface e) No ascites f) Slow growing Q. How can laparotomy findings be helpful to differentiate a benign tumor from a malignant one? A malignant ovarian can be differentiated from a benign one on laparotomy by the following features: a) Ascites – Present and often it is hemorrhagic. These are tiny, calcified bodies observed in cases with serous cyst adenoma of the ovary. The important feature of the functional cysts of the ovary are: a) It is due to temporary hormonal disorders b) Usually 6–8 cm in diameter c) Usually asymptomatic d) Unilocular e) Regresses spontaneously f) Contains clear fluid.

Frontal diagram of the fusion fasciae of left and right colon, pancreatic head and duodenum and pancreatic body and tail. The fusion fascia of the left colon (1) fixes the meso of the descending colon to the posterior primitive parietal peritoneum. The superior limit, which covers part of the retroperitonealized pancreatic body and tail, is the line connecting the origin of the superior mesenteric artery to the left angle of the transverse mesocolon. The inferior limit begins a little left from the midline, in front of the promontory, and descends along the inner border of the psoas muscle, at the upper root of the sigmoid mesocolon. The retroduodenopancreatic fusion fascia of the duodenal loop (2) fixes the mesoduodenum and pancreatic head to the posterior primitive parietal peritoneum and to the fusion fascia of the left mesocolon, respectively, right and left from the midline. The superior limit above the root of the transverse mesocolon is the common hepatic artery. The left limit, below the radix of the transverse mesocolon, is short, starting below the superior mesenteric artery and extending to the duodenojejunal angle. The retropancreatic fusion fascia (3) fixes the dorsal mesogastrium, containing pancreatic body and part of the tail, to the posterior primitive parietal peritoneum. The fusion fascia of the right colon (4), located between cecum and transverse mesocolon, fixes the meso of the ascending colon to the posterior primitive parietal peritoneum and the duodenum and its fused meso, containing the caudal part of the pancreatic head. Note the loose areolar tissue (arrows) between this mesenteric fat and the pancreatic tail, representing the fusion fascia posterior to the transverse mesocolon medially and the cranial extension of the left retromesenteric plane, also called left fascia of Toldt, laterally. A space, also bridged by loose areolar tissue (arrowheads), appears between the pancreatic tail and perirenal space, representing the fusion fascia between the left pancreaticoduodenal compartment and primitive retroperitoneum. The left colonic compartment is demarcated from the primitive retroperitoneum by loose areolar tissue representing the left retromesenteric plane (black arrows).
