Use of parenteral magnesium sulphate in eclampsia and severe pre-eclampsia cases in a rural set up of Bangladesh.

This was a quasi-experimental interventional study to see the role of injection magnesium sulphate in eclampsia and severe pre-eclampsia patients at community level in a rural set up before referral to the hospital. This study was conducted on 265 cases of eclampsia and severe pre-eclampsia over a period of six months from July 2001 to December 2001. Among 265 cases, 133 were in intervention group who had received loading dose of injection magnesium sulphate before referral and the rest 132 were in non-intervention group, had not received injection magnesium sulphate before admision in hospital. The number (mean +/- SD) of convulsion before treatment in intervention and non-intervention groups were 4.7 +/- 2.64 & 6.86 +/- 2.97 respectively. Recurrence of fits observed more in non-intervention group and the difference was statistically significant (p<.001). Mean (+/- SD) time taken to regain full consciousness was 12.0+9.6 and 17.4+7.4 hours in the intervention and non-intervention group respectively (p<.05). Control of convulsion by loading dose of 10 gm of injection magnesium sulphate was achieved in 94.0% of the intervention group and 74.0% in non-intervention group. There was only 3(2.3%) maternal death in study group whereas in non-intervention group maternal death was 14(10.4%) and the difference was highly significant (p<.005). Fourteen (13.7%) babies were still born in intervention group and 21(20%) in non-intervention group. The difference was statistically highly significant (p<.001). Remarkable achievements were obtained through use of magnesium sulphate at the community level at rural setting among the eclampsia and severe pre-eclampsia cases.

Effect of oestrogen replacement therapy on bone mass in post-menopausal Bangladeshi women.

The female population comprises 48.66% of our total population, of which 10.30% are above the age of 49, many of whom are post-menopausal. Menopause is associated with bone-loss and its consequences. Hormone replacement therapy (HRT), particularly replacement of estrogen, prevents bone-loss. We undertook this prospective case-controlled study to find out whether or not HRT is beneficial to our women. A total of 106 patients were studied, amongst them 60 were cases and 46 were controls. The women in the first group were given either conjugated equine estrogen alone (surgical menopause group) or conjugated equine estrogen plus cyclical progesterone (natural menopause group). Results showed that there was 4.29% increase in bone mineral density in women who received hormone replacement therapy (HRT). This increase was 5.23% in early and 3.56% in late menopause group. Women with natural menopause gained more bone mass (4.22%) than women with surgical menopause (3.9%). Our results also showed that women who denied HRT (controls) lost bone mass (5.26%), the loss was more in those with surgical menopause (6.24%) than those with natural menopause (4.87%). Therefore it can be concluded that post-menopausal hormone replacement therapy prevents bone-loss. However, to evaluate the beneficial effect of long-term HRT, further studies with larger samples are recommended.

Magnesium sulphate versus diazepam in the management of eclampsia.

This clinical trial was conducted to compare the anticonvulsant response of magnesium sulphate and diazepam in the management of eclampsia. The study was carried out at the eclampsia unit of Dhaka Medical College Hospital during the period from October, 1995 to January, 1996. Two hundred consecutive admitted patients were recruited for the study and randomly assigned to two treatment groups: magnesium sulphate and diazepam. One hundred patients received injection magnesium sulphate and another one hundred received injection diazepam. All patients of both the group were matched for baseline characteristics. Convulsion was controlled in 95% of the patients of magnesium sulphate group and 74% of the patients of diazepam group (p < .0005). The mean controlling time is also significantly lower in magnesium sulphate group than diazepam group (8.50 hours vs 9.39 hours). Patients of magnesium sulphate group regain consciousness much earlier (mean time 20.62 hrs.) than the patients of diazepam group (mean time 40.62 hrs.). No significant difference was observed in controlling blood pressure and foetal outcome. The study finding shows that magnesium sulphate has some advantage over diazepam in controlling convulsion and regaining consciousness. If magnesium sulphate can be made available in the market by local production it may be recommended to use this drug in the primary health care without any hazzard before referring to other hospital.

Clinical down staging of cancer cervix with cytology.

A prospective study was carried out on 1500 patients attending the Gynaecology outpatient department of three referral hospitals in Dhaka City. These patients were selected on some selected clinical criteria to correlate several clinical markers (clinical down staging) with that of Pap's smear for early detection and secondary prevention of cancer cervix. Speculum examination and Pap's smear were done in all cases. Among 1500 women, 224 had abnormal Pap's smear. Histologic examination of specimens from these cases showed chronic cervicitis in 45 cases, dysplasia in 84 and squamous cell carcinoma in 95. Carcinoma was found in 130. Thus, there were 297 Pap's smear negative cases were biopsied on clinical ground. 225 cases of invasive carcinoma. From this study, it seems that clinical downstaging with cytology programme has to be started immediately throughout the country for diagnosis of carcinoma of the cervix in its preinvasive and potentially curable stage.
