BACKGROUND & OBJECTIVES: Anti-neutrophil cytoplasmic antibodies in active necrotizing and crescentic glomerulonephritis are associated with systemic vasculitides like Wegener's granulomatosis, Microscopic polyangitiis and Churg Strauss Syndrome. This study shows the incidence of ANCA with specificities to Myeloperoxidase and Proteinase3 in MPA cases and gives the correlation of ANCA with Birmingham Vasculitis Activity Score. MATERIAL & METHODS: Eighteen cases of MPA were diagnosed as per Chapel Hill Consensus Criteria. ANCA was detected by indirect immunofluorescence microscopy using fluorescence and Confocal Laser Scanning Microscopes. Anti-MPO and anti-PR3 were identified by commercial ELISAs and anti-MPO subclass and IgG isotypes were also detected. RESULTS: MPA patients showed a male preponderance with BVAS ranging from 17-30. Systemic involvement was seen in 88.9%, lower respiratory tract involvement in 77.8% and upper respiratory tract in only 33.3% cases. All these patients had perinuclear pattern on IIF, where titers ranged from 80-640 and ELISA showed anti-MPO; values ranging from 20-80 units/ml. IIF and ELISA showed a good correlation (r=0.77). Two patients having FPGN had dual specificities and had both anti-MPO and anti-PR3 which could be picked up only by ELISA. A good correlation (r=0.78) was observed between BVAS and ANCA levels as well. IgG ANCA was detected in 88.7% and 11.1% had IgG+IgM and IgG1+IgG4 ANCA was detected in 50% patients. CONCLUSION: p-ANCA with anti-MPO is highly specific for MPA; both IIF and ELISA should be carried out for true positivity and to identify rare cases of dual specificities. Confocal laser scanning microscopy is useful in identifying ANCA patterns especially when ANA is also positive. ANCA testing with BVAS assessment will surely help in early diagnosis and estimating the severity of this life threatening disease.

Effect of various stressor agents on the adrenergic system in brain had been studied extensively. However, reports on the effect of stress on various parameters of central cholinergic system are scanty. And very little is known about the effect of noise stress on the cholinergic system in brain. Hence, it was decided to elucidate the effect of acute noise stress on the activity of the enzyme acetylcholinesterase in discrete areas of brain in albino rats. Male albino rats of Wistar strain were subjected to acute noise stress for 30 minutes. The noise of pure sine wave tone was produced by using a function generator and was amplified. The frequency of noise generated was 1 kHz and the intensity was set at 100 dB. The total acetylcholinesterase activity was determined in the tissues of cerebral cortex, corpus striatum, hypothalamus and hippocampus of brain in these rats. The enzyme activity was estimated by colorimetric method using acetylthiocholine iodide as the substrate. The values were compared with the enzyme activity in the control rats. The activity of the enzyme increased significantly in all the four regions of the brain in rats after exposure to noise stress for 30 minutes. The results of the study indicate that the exposure to acute noise stress could modulate the cholinergic system in these areas of brain in rat.

BACKGROUND: As ectopic pregnancy is associated with significant maternal mortality and morbidity it may be worthwhile to find alternative surgical method to traditional laparotomy. AIMS: To compare the efficacy, safety and cost effectiveness of minilaparotomy surgery for ectopic pregnancy cases with standard laparotomy method. SETTING AND DESIGN: A total of 60 patients of ectopic pregnancy were randomized for minilaparotomy and laparotomy (30 cases each) for three years from January. 1998 to March 2001 in a medical college hospital. MATERIAL AND METHODS: Patients history, clinical examination, intraoperative, preoperative and postoperative data were recorded and compared in minilaparotomy and laparotomy groups. STATISTICAL ANALYSIS USED: Chi-square and Fischer chi-square test is used using P value of less than 0.05 as level of significance. RESULTS: Mean operative time was significantly less in minilaparotomy (38 minutes) than in laparotomy group (54 minutes). Postoperative complications were fever in 4(13.33%) and 6(20%) cases, paralytic ileus in 3(10%) and 8(26.66%) cases, urinary tract infection in 2(6.66%) and 3(10%) cases and wound infection in 1(3.33%) and 5(16.66%) cases respectively in the two groups and were significantly less in the minilaparotomy cases. Mean day of mobility, starting normal diet and discharge from the hospital were 10 hours and 24 hours, 1.5 days and 3.1 days and 3.4 days and 6.9 days respectively in the two groups and were significantly less in the minilaparotomy group than the laparotomy group. CONCLUSIONS: Surgery by minilaparotomy technique in ectopic pregnancy cases appears to be a safe and feasible method and is superior to conventional laparotomy as there are minimum perioperative and postoperative complications and patients can be discharged early from the hospital without the need of expensive equipment.

We herein report a case of a pregnant woman with previous cesarean section whose uterus herniated in an incisional hernia of the anterior abdominal wall at 34 weeks of pregnancy. Incarceration of the pregnant uterus in an incisional hernia is a rare but serious obstetric situation. Treatment is conservative till term followed by delivery and herniorrhaphy as was done in our case and it was associated with successful outcome.

A 28-years-old female presented with severe autoimmune hemolytic anemia (AIHA), warm antibody mediated, and right side tubo-ovarian (TO) mass. There was sub-optimal response to immunosuppressive therapy (IST). Eight months later she underwent ovarian cystectomy which resulted in complete remission of AIHA without the need for IST. Pathological examination of the TO mass revealed benign ovarian cyst. Our case highlights the need to search for ovarian cyst/mass in females presenting with AIHA. Since immunosuppressive therapy is usually ineffectual in AIHA associated with ovarian cyst, it may be appropriate to contemplate surgery before embarking on IST in such cases.
