Vaginal Estrogen Therapy in Postmenopausal Overactive Bladder

Objective: To assess the efficacy of vaginal estrogen therapy in postmenopausal overactive bladder (OAB). Study design: It is an OPD (outpatient department) based prospective study. Postmenopausal women attending gynecology OPD with complaint of OAB were enrolled for the study. Women fulfilling the criteria for the study were given estradiol 2 mg vaginal tablet everyday for 2 weeks, then weekly twice for 10 weeks. Patients were assessed by 3-day bladder diary, Patient Global Impression scale, before and after the therapy. Results: Ninety-three patients completed the study. Increased frequency of micturition was cured in 92.5% cases; urgency and urge incontinence was cured in 74.2% cases. Patient’s subjective feeling of improvement scale revealed only 12.9% women felt either no change or little better; rest all were happy. Conclusion: Local estrogen therapy in postmenopausal women with OAB resulted in a good outcome.

Carotid artery involvement in patients of atherosclerotic coronary artery disease undergoing coronary artery bypass grafting.

BACKGROUND: Patients with concomitant critical carotid and coronary artery disease are at risk of major neurological events while undergoing coronary artery bypass grafting. The presence of carotid artery stenosis increases the stroke rate in the perioperative period. In an effort to reduce the stroke rate, many institutions perform routine preoperative noninvasive assessment of the carotid arteries. METHODS AND RESULTS: We analyzed the clinical and laboratory data of 1,200 patients who underwent coronary artery bypass surgery in the last 2 years. Carotid Doppler was normal in 186 patients (15.5%), and showed <30% stenosis in 796 (66.3%), 30%-50% in 110 (9.2%), 50%-70% stenosis in 64 (5.3%) and critical (>70%) stenosis in 44 (3.7%) patients. Conventional risk factors such as hypercholesterolemia, hypertension, smoking and family history were not independent predictors of carotid artery stenosis. However, diabetes as a risk factor had a significant association with carotid artery disease (79.6% v. 43.8%, p<0.02). There was a trend towards increased prevalence of carotid artery stenosis in patients with > or = 2 risk factors (84.3% v. 68.8%). Patients with significant carotid artery stenosis had severe coronary artery disease (triple-vessel disease 93.3%, left main coronary artery disease 12.0%). Out of 44 patients with critical carotid artery stenosis, 27 were subjected to carotid angiography. Doppler findings correlated well with angiography. Seventeen patients underwent carotid artery intervention. None had any perioperative neurological events. A total of 5 (0.4%) patients had a major stroke. Coronary artery bypass grafting was done in 27 patients with critical stenosis without any intervention. The stroke rate (11.1%) was higher in these patients compared to patients with < 70% carotid artery disease or post-carotid intervention (2.5%) patients. Thus, untreated >70% carotid artery stenosis was associated with a higher stroke rate. CONCLUSIONS: Doppler screening of the carotid artery is helpful in detecting the subgroup of patients at increased risk of stroke. Patients with critical carotid artery stenosis should be subjected to angiography. Prophylactic intervention may reduce the occurrence of stroke in the perioperative period.

Coronary stenting without pre-dilatation: an observational study.

Conventional coronary stenting is done after pre-dilatation of the lesion. The bleeding complications and incidence of subacute stent thrombosis have been reduced significantly by the use of antiplatelet agents and high pressure balloon inflation to ensure complete stent expansion. Elective stenting also can be done without pre-dilatation by "stent alone technique." This approach significantly reduces the procedural cost and ischaemia time, avoiding potential complications such as abrupt vessel closure because of extensive dissection after conventional angioplasty and prior to stent deployment. Eighty patients of stable angina pectoris suitable for coronary angioplasty underwent stenting without pre-dilatation. Out of the 100 stents used, 38 were hand-crimped and 62 were pre-mounted. The target vessels were left anterior descending artery in 56 percent, right coronary artery in 32 percent and left circumflex in 12 percent. The procedure was successful in 88 percent lesions. In 12 percent stenting could be done only after pre-dilatation. In all these, there was proximal tortuosity and calcification. The fluoroscopy time was 10.2 +/- 4.5 minutes. The average number of balloons used per lesion was 1.08. Stent embolisation occurred in only one patient. There were no major adverse cardiac events in any of the patients. Thus stenting without pre-dilatation is safe. Patients who are eligible for stenting without pre-dilatation are those with stable angina pectoris without fluoroscopically visible calcium or coronary artery tortuosity and with lesions of moderate complexity.

Multiple tubercular ulcer perforation of ileum in an AIDS patient: case report.

Intestinal perforation is an extremely uncommon complication of Mycobacterium tuberculosis (MTB) infection. We report a case of HIV infection in a male injecting drug user (IDU) with intestinal tuberculosis complicated with multiple ileal perforations at the Regional Institute of Medical Sciences Hospital, Imphal, Manipur. The emergency surgical therapy supported by antitubercular drugs (ATT) and parenteral nutrition saved the life of this patient who presented in a critical state of shock. The patient manifested with extrapulmonary tuberculosis, which is one of the criteria of AIDS. The authors stress the possibility that in future, tubercular complication till now considered atypical, may become more frequent.

Elective coronary artery stenting--immediate and follow up results.

Elective coronary artery stenting was performed in 242 consecutive patients in our centre for complex lesions (Type B, C), proximal lesions, restenotic lesions, total occlusion and venous grafts. The procedural success rate was 94.21%. Three patients (1.23%) required emergency coronary artery bypass surgery. Acute and sub-acute thrombosis rate was 1.26% and 4.13%, respectively. There was one in-hospital death (0.41%). 164 patients were followed up clinically for a mean period of 11 +/- 6 months (range 1 month to 30 months). Angiographic follow up was done in 68 patients with a restenosis rate of 16.17%.

Atypical presentations of falciparum malaria.

To identify the uncommon presentations of falciparum malaria in an endemic area and to assess the outcome of treatment, a study was carried out on 35 proved cases whose clinical presentations were either dominated by features other than fever or the history of fever was totally absent. Both urban and rural patients were included. Seventeen cases (48.3%) presented with features of cerebral malaria. Acute abdomen, urticaria, and unexplained shock were the other atypical presentations. Five cases (14.3%) of cerebral malaria died. We conclude that awareness of atypical presentations is important to detect cases of falciparum malaria in an endemic area. Intravenous quinine may need to be given promptly even when cerebral malaria is diagnosed empirically.
