Abortion Incidence and Postabortion Care in Rwanda

Abortion is illegal in Rwanda except when necessary to protect a woman's physical health or to save her life. Many women in Rwanda obtain unsafe abortions; and some experience health complications as a result. To estimate the incidence of induced abortion; we conducted a national sample survey of health facilities that provide postabortion care and a purposive sample survey of key informants knowledgeable about abortion conditions. We found that more than 16;700 women received care for complications resulting from induced abortion in Rwanda in 2009; or 7 per 1;000 women aged 15-44. Approximately 40 percent of abortions are estimated to lead to complications requiring treatment; but about a third of those who experienced a complication did not obtain treatment. Nationally; the estimated induced abortion rate is 25 abortions per 1;000 women aged 15-44; or approximately 60;000 abortions annually. An urgent need exists in Rwanda to address unmet need for contraception; to strengthen family planning services; to broaden access to legal abortion; and to improve postabortion care.

Bilayer tablet technology: An overview.

Over the past 30 years as the expense and complications involved in marketing new drug entities have increased, with concomitant recognition of the therapeutic advantages of controlled drug delivery, greater attention has been focused on development of sustained or controlled release drug delivery systems. Bilayer tablet is new era for the successful development of controlled release formulation along with various features to provide a way of successful drug delivery system.

Evaluation of hepatoprotective activity of Clerodendrum serratum L.

The ethanol extract of C. serratum roots and ursolic acid isolated from it were evaluated for hepatoprotective activity against carbon tetrachloride induced toxicity in male Wistar strain rats. The parameters studied were estimation of liver function serum markers such as serum total bilirubin, total protein, alanine transaminase, aspartate transaminase and alkaline phosphatase activities. The ursolic acid showed more significant hepatoprotective activity than crude extract. The histological profile of the liver tissue of the root extract and ursolic acid treated animal showed the presence of normal hepatic cords, absence of necrosis and fatty infiltration as similar to the controls. The results when compared with the standard drug silymarin, revealed that the hepatoprotective activity of the constituent ursolic acid is significant as similar to the standard drug.

Pre-cancerous lesions of stomach.

Total 39 cases of carcinoma stomach were noticed out of 142 malignant tumours of GIT (27.46 percent). Histologically maximum cases were of diffuse type (56.41 percent) followed by intestinal type (35.89 percent) and indolent mucoid carcinoma (7.69 percent) of the stomach. The surrounding epithelium showed lot of changes in the intestinal type of carcinoma stomach. About 78.57 percent showed intestinal metaplasia, 14.28 percent of these cases showed chronic gastric ulcer and severe dysplasia (carcinoma in situ) and another 14.28 percent revealed villous adenoma with carcinoma in situ. In contrast to this, in diffuse variety, only 13.63 percent cases revealed intestinal metaplasia, 27.27 percent showed basal cell hyperplasia, stratification of the epithelium of crypts and diffuse infiltration of mucosa by malignant cells and 4.54 percent showed atrophic gastritis also. In mucoid carcinoma all cases had basal cell hyperplasia and stratification of crypts. Hence these conditions should be taken as premalignant lesions of stomach and should be cured in proper time.

Clinicopathological studies of carcinoma oesophagus with special reference to changes in surrounding epithelium.

A total 17 cases of carcinoma oesophagus were studied in a period of 2 years. Ten patients (58.82%) were males and rest were females. Maximum cases (64.70%) were seen in 5th and 6th decades. Majority of the patients belonged to low socio-economic group (47.05%) followed by middle socio-economic group (41.17%). Dysphagia was present in all cases, followed by weight loss 52.94% and other symptoms. Cancer was equally distributed in middle third and lower third of the oesophagus (41.18% in each group) only in 3 cases it was in upper third of the oesophagus. Histologically 70.5% tumours were squamous cell carcinoma, 17.64% were adenocarcinoma and 11.76% were undifferentiated carcinoma. Surrounding epithelium in 17.64 per cent cases showed chronic oesophagitis, 4 cases (23.52%) showed acanthosis and dysplasia, and two cases revealed carcinoma in situ. Hence findings of oesophagitis, acanthosis, dysplasia, carcinoma in situ suggest that oesophagitis and acanthosis may be considered as precancerous lesions.

Distribution of silfusomidine in tissues of poultry.

The biological half life, blood level and tissue dispersion of sulfisomidine in poultry have been studied. The biological half life was observed to be 40 minuts. Following single dose (275 mg/kg) oral administration, the peak blood level of 13.92 mg% was found at 2 hr and the liver and small intestine showed highest drug residue at the end of 24 hr.
