Study of interspouse communication and adoption of family planning and immunization services in a rural block of Varanasi District.

Interspouse communication was studied in some pertinent areas which have an important bearing on day to day transactions. The level of such communication measured on a three-point scale was studied for its role on acceptance of family planning and immunization services. 200 currently married females residing with their husbands in a rural block of Varanasi, in the reproductive age group, with at least one child aged 1-3 years were selected and interviewed. Scores were ascribed for 12 selected items of conversation according to frequency of conversation on a three point scale based on which high, medium and low communicators were delineated. In this study high, medium and low communicators were found to be 14%, 40% and 45% respectively. Topics of importance which never featured in interspouse communication were menstrual problems (44%), when to have first child (82.5%) and birth spacing (48.5%). Interspouse communication was better in upper castes and joint families. Literacy status of both husband and wife and per capita income of the family revealed positive relationship with inter-spouse communication. Adoption and practice of family planning methods as well as full immunization coverage of the child in the family were observed to be higher among high and medium communicators as compared to low degree of communcators (p < 0.001).

Visual evoked potential & brainstem auditory evoked potentials in acute attack & after the attack of migraine.

PURPOSE: To study the effect on visual evoked potential (VEP) and brainstem auditory evoked potential (BAEP) at time of acute attack and after 7 days of the attack of migraine. MATERIAL AND METHODS: We studied BAEP and pattern reversal VEP in 25 patients during acute attack and after 7 days of the attack. The diagnosis of migraine was established according to criteria given by international headache society (IHS). Peak and interpeak latencies (IPL's) of BAEP and P100 latency of VEP were the main criteria to judge abnormalities. RESULTS: There were prolonged peak and interpeak latencies in BAEP and prolonged peak latency (P100) in VEP at the time of acute attack of migraine. The data of these abnormal recording were highly significant. After 7 days when the attack was over, we recorded the BAEP and VEP again. The observation obtained at this time was comparable to normal values. CONCLUSIONS: From the observation of this study we can safely conclude that in acute attacks of migraine there may be some pathological changes in different areas of brain and brainstem, producing changes in evoked potential which are statistically highly significant. However, these changes are reversible, as the values of BAEP & VEP on 7th day after the attack were comparable to those observed in normal healthy control.

Leprosy and herpes zoster; an association or dissociation?

Nerve involvement is common to the pathogenesis of both leprosy and herpes zoster. We report two cases of borderline leprosy in which the skin lesions characteristically spared the healed zoster scar. Possible mechanisms and relationship are discussed.

Laparoscopic surgery in the developing world. An overview of the Indian scene.

We present experience of laparoscopic surgery commencing in 1972 with diagnostic laparoscopy in a Surgical Unit in Bombay. By 1990 we had completed 2800 diagnostic laparoscopies with no mortality, 0.08% complication rate, 85% positive diagnosis and an instrument cost of about Rs. 35 (US $ 1.2) per patient. We have over the past 5 years performed 890 laparoscopic cholecystectomies (LC) with no mortality, no blood transfusion, and one CBD injury. With reusable equipment, monopolar diathermy and selective cholangiography, LC is cost-efficient in a developing country. Over this period over 60 laparoscopic appendectomies were performed, with the use of catgut ligatures and self-made endo-loops. laparoscopic appendectomy is cost-effective under our conditions. We have done 46 hernia repairs, and by contrast find it far more expensive and with inferior results to standard hernia repair. Advanced laparoscopy for ulcer and reflux disease, bowel resection, retroperitoneal and thoracic laparoscopy are being given a trial in several centres in the developing world.

Immediate and six-month outcome of self-expanding Wallstent for long lesions in native coronary arteries.

Between April and December 1996, 50 less-shortening Wallstents were deployed in the native coronary arteries of 44 patients, with lesions more than 20 mm long and minimum vessel diameter of at least 3.0 mm. There were 39 males and 5 females with an age range of 35-77 years. The majority (70.4%) had multivessel disease (MVD). The target vessel was LAD for 17 (34%), RCA 23 (46%) and LCx-OM for 10 (20%) stents. All lesions were type C, according to the ACC/AHA Task Force Classification. The length of the lesions ranged from 21-60 mm (mean: 31 +/- 8). The stent selection was based upon oversizing by 1.5-2.0 mm compared to the minimum vessel diameter, and covering approximately 4-5 mm of the apparently normal vessel on either side of the target lesion. The stent was deployed successfully without any major complications, including myocardial infarction, emergency coronary artery bypass grafting (CABG) and death in 43 out of 44 (97.7%) patients. One patient in whom there was failure to reach the target site with stent, developed non-Q wave inferior myocardial infarction. Post-discharge, two patients reported to have died within one month after the procedure. The event-free survival, defined as the absence of angina, myocardial infarction, need for revascularisation or death was 93.2 percent at 30 days and 84 percent at 6 months following stent implantation. From our data, it is concluded that (i) the delivery of the new, less-shortening, self-expanding Wallstent at the target site was possible in almost all the cases; (ii) clinical success with < 30 percent residual diameter stenosis could be achieved in approximately 98 percent of cases, and (iii) there was an impressive event-free survival of 84 percent at 6 months of follow-up. The occurrence of 2 deaths during the first 30 days, however, necessitates close supervision for possible subacute stent thrombosis. The results of angiography after six months would help to define the true incidence of restenosis.

Nucleolar organiser regions in different colonic epithelia.

The argyrophilic technique (AgNOR) was applied to paraffin sections of 10 acute self-limited colitis, 15 ulcerative colitis (UC), 5 ulcerative colitis with indefinite dysplastic change, 10 adenomatous polyps, 20 colorectal adenocarcinomas and 10 normal colorectal mucosa. The mean number of nucleolar organiser regions (NORs) per nucleus ranged between 1.62-2.00 (95% CI 1.77-1.93) for normal colon, 2.47-3.80 (95% CI 2.71-3.21) for acute colitis, 1.66-2.75 (95% CI 2.13-2.44) for UC, 3.60-4.00 (95% CI 3.67-3.94) for UC with indefinite dysplasia, 3.00-4.04 (95% CI 3.41-3.81) for adenomatous polyps and 3.59-6.70 (95% CI 4.04-4.72) for colorectal adenocarcinoma. The differences observed were statistically significant. There was a significant difference of AgNOR counts between adenomatous polyp and UC with indefinite dysplasia in comparison to those observed in regenerative epithelium of acute colitis and UC without dysplasia. Hence the technique may be used as an adjunct to routine histology for delineating dysplastic changes in colonic epithelium.

Elective coronary stenting after recanalization for chronic total occlusion: clinical and angiographic follow-up results.

Percutaneous transluminal coronary angioplasty (PTCA) for chronic totally occluded coronary arteries is associated with a significant residual stenosis and a high incidence of restenosis. Between March 1995 to February 1997, recanalization of chronic total occlusion (CTO) was attempted in 95 patients, of whom 79 (83.1%) were dilated successfully using balloon angioplasty, rotablation or both. Forty two patients underwent elective stent implantation to evaluate the influence of stenting on immediate results and clinical as well as angiographic outcome on long-term follow-up. There were 39 males and 3 females, with a mean age of 51 +/- 8 years. The majority (69.1%) had multivessel disease. The target vessel was LAD in 25 (58.1%), RCA in 12 (27.9%), LCx-OM in 5 (11.6%) and ramus in 1 (2.3%). After recanalization and adequate predilatation, various types of stents were deployed successfully at the target site in all patients, using high pressure intrastent balloon dilatation. The luminal diameter stenosis reduced to 47 +/- 15 percent after balloon angioplasty and < 10 percent in all, after stent implantation. There were no in-hospital major complications, including subacute stent thrombosis, myocardial infarction, need for emergency bypass graft surgery or death. The follow-up data is available in 36 patients, ranging from 1-22 months (mean: 7.4 +/- 4.7; median: 6). Of these, 32 (88.8%) were free of angina at their last visit, 3 (8.3%) required target lesion revascularization and 2 patients died, one at 3 weeks and the other at 6 months after the procedure. The event-free survival, estimated by the Kaplan-Meier survival curve was 97.3, 82.8 and 77.25 percent at one, 6, and 12 months, respectively after stenting. Out of 29 eligible patients, 20 underwent repeat coronary angiography after 6 months, which revealed restenosis in 5 (25%). In conclusion, our study shows that elective coronary stenting following successful recanalization of chronic total occlusion produces an excellent immediate result and reduces the recurrence of angina, target lesion revascularization and angiographic restenosis on long-term follow-up.
