A rare case of adenocarcinoma of the supernumerary ovary is reported. This rarely encountered gynecological entity posed difficulty in diagnosis and management. However, the behavior is similar to adenocarcinoma of ovary originating from a normal site. 相似文献

OBJECTIVE: To review the maternal and fetal complications in pregnant women with sickle cell disease and to compare their pregnancy outcome with those of controls. DESIGN: A case-control study. SETTING: Ministry of Health hospitals in Bahrain. SUBJECTS: 147 pregnancies in 140 women with sickle cell disease and 294 controls matched for age and parity. MAIN OUTCOME MEASURES: The characteristics of women who had crises, the frequency of the crises, hypertensive disorders of pregnancy, infection, diabetes, perinatal mortality and the delivery statistics in the index and control women. RESULTS: Maternal mortality was 1.4% and perinatal mortality was 73.3/1000 total births in women with sickle cell disease, there were no maternal deaths and the perinatal mortality was 6.8/1000 births in the control group. Anaemia was treated by blood transfusion in 47% of women with sickle cell disease and, of these, 39% had a crisis that appeared to have been precipitated by the transfusion in the absence of any other predisposing factors. The presence of raised HbF did not decrease the number of crises but reduced their severity. CONCLUSION: Pregnancy in women with sickle cell disease should be monitored very closely as it constitutes a high risk to both the mother and the baby. 相似文献

Two children out of three siblings of a family presented with tiredness, fatigue, and breathlessness for more than 6 months. Examination of peripheral blood smear, bone marrow aspirate, and a positive acidified serum test (HEMPAS) revealed these children to be a case of congenital dyserythropoietic anemia type II. This case is reported because of its rarity. 相似文献

Fenfluramine, an amphetamine derivative used in the treatment of obesity, has been evaluated in vivo in the bone marrow cells of Swiss albino mice using two cytogenetic endpoints for assessing its genotoxic and clastogenic potentials. Concentrations of 0.75, 1.5, 3.0, and 5.0 mg/kg b.w. were administered orally for the study of sister chromatid exchange frequencies and chromosome aberrations (CA). SCE frequencies showed a positive dose response; 1.5 mg/kg being the minimum effective concentration. Fen caused a prolongation of cell cycle at all concentrations. Except for the minimum therapeutic dose (0.75 mg), all other doses (1.5, 3.0, and 5.0 mg) showed a significant increase in the percentage of damaged cells over that of the vehicle control. The degree of clastogenicity was directly proportional to the dosage used and inversely related with the duration of treatment. A gradual reduction of the clastogenic potential was observed after 12 and 24 hr of exposure, indicating that the maximum effect occurs at the middle or late synthetic phase of the cell cycle. This study, probably the first detailed screening of the drug for its genotoxicity, shows that Fen is moderately clastogenic and a DNA damaging agent in vivo. 相似文献

OBJECTIVE: To determine the impact of nutritional status on peritonitis in patients on continuous ambulatory peritoneal dialysis (CAPD) in a developing country. METHODS: 56 patients with end-stage renal disease on CAPD were randomly selected for this study. These patients were assessed for nutritional status and peritonitis episodes. Nutritional parameters were assessed by anthropometry, diet, body mass index (BMI), Nutritional Risk Index (NRI), serum albumin level, and Subjective Global Assessment (SGA). Based on SGA, patients were categorized into either group 1 (malnutrition, n = 31) or group 2 (normal nutritional status, n = 25). Peritonitis was considered the primary outcome and was compared between the two groups. RESULTS: Demographic profiles, Kt/V, creatinine clearance, and mean follow-up of the two groups were similar. Number of peritonitis episodes was significantly higher in patients with malnutrition (25/31) compared to patients with normal nutritional status (4/25) (p = 0.001). Mean peritonitis rate per patient per year was also significantly higher in patients with malnutrition (0.99 +/- 1.07) compared to patients with normal nutritional status (0.18 +/- 0.42) (p = 0.007). On univariate analysis, malnutrition based on SGA (p = 0.009), NRI (p = 0.02), serum albumin level (p = 0.005), and calorie intake (p = 0.006) was a significant predictor of peritonitis. On multivariate Cox regression analysis, only SGA (p = 0.001, odds ratio 0.08, 95% confidence interval 0.02-0.36) was found to be a significant predictor of peritonitis. On general linear model, the observed power of prediction of peritonitis was 0.96 based on SGA. On Kaplan-Meier survival analysis, peritonitis-free survival in patients with normal nutrition (42 months) was significantly higher compared to patients with malnutrition (21 months) based on SGA (log rank p = 0.003). CONCLUSION: We conclude that peritonitis rate is high in patients with malnutrition and that malnutrition indices, especially SGA, can predict the peritonitis rate in CAPD patients. 相似文献

An anti-tumour drug, 5-fluorouracil (5 FU) was used to deplete heterophils in 11-day-old white leghorn chickens. The reduction in heterophil numbers was monitored by total and differential white cell counts in the peripheral blood. Three days after injection of 5 FU, when the heterophil numbers were significantly reduced, chickens were infected with the Massachusetts strain of infectious bronchitis virus (IBV). Following infection, although the numbers of birds exhibiting clinical signs (nasal exudate) were significantly higher in the 5 FU treated group, the consistency of the nasal exudate was characteristically thin and watery. No significant differences were seen in the virus titres in trachea, lung and kidney between normal and heteropaenic chickens infected with IBV. However, the epithelial cell damage in the tracheal sections was less in the heterophil-depleted chickens. 相似文献

Twenty four patients with angio-immunoblastic lymphadenopathy (AILD) presenting between 1974 and 1985 have been reviewed. Clinical features at presentation included rash, fever, lymphadenopathy and hepatosplenomegaly in 75% of patients. Polyclonal hypergammaglobulinaemia was seen in 19/20 patients; 5 had normal immunoglobulin levels. Combination chemotherapy with MVPP was the optimal treatment with 6/7 patients achieving complete remission. Duration of remission ranged from 9 months to 4 years and was significantly longer in patients achieving complete as opposed to partial remission. In 6 patients phenotype studies were performed on single cell suspensions and immunoperoxidase studies on frozen sections of 7 lymph nodes. There was a reversal of the normal T suppressor/helper cell ratio with a predominance of T suppressor cells. Loss of normal B follicles was observed histologically in all except one lymph node. Germline configuration of the beta B-chain of the T cell receptor was observed in lymph nodes of 4 patients with AILD, and a rearranged T cell receptor was observed in 1 patient in whom a second lymph node biopsy had shown alteration of the histological picture to that of T-zone lymphoma. Frozen sera of 15 patients were screened for antibodies to HTLV I and III and were found to be negative. 相似文献

A 65 year old Punjabi male presented with an exophytic lesion, 3 Cm. in diameter, which was pedunculated, on the attached
gingiva. It was situated on the right side, near the motars. On histological examination, it was diagnosed as plasma cell
granuloma. 相似文献

The relationship between peripheral blood natural killer (NK) cells and reproductive failure is one of the most controversial areas in reproductive medicine. Amidst much publicity, peripheral blood NK cell testing is being promoted as a useful diagnostic test to guide the initiation of a variety of immunosuppressive therapies amongst patients with either recurrent miscarriage or infertility. We contend (i) that at present there is no scientific basis for the introduction of NK cell testing into routine clinical practice, and (ii) that the use of immunosuppressant agents based on the results of such testing may potentially be harmful. 相似文献
