The impact of training traditional birth attendants on the utilisation of maternal health services.

The impact of training traditional birth attendants (TBAs) on the utilisation of maternal health services at a rural health training centre in India has been studied. Records of the utilisation of the services for two periods of six months each (one before training and one after) have been analysed. A marked improvement in the registration of antenatal cases at an earlier date in pregnancy has been observed. The average number of visits to antenatal clinics, the immunisation against tetanus, and the presence of trained personnel at the time of delivery all showed considerable improvement after the local TBAs had been trained and motivated. The differences observed in the two series were statistically significant.

Histochemical studies on the distribution of alkaline phosphatase, acid phosphatase, 5-nucleotidase and ATPase in various reproductive tissues of certain digenetic trematodes.

Out of other functions performed by vitellaria in digenetic trematodes, their role in the formation of shell globules and shell membrane of the capsule, as well as in the excretion of iron with the help of vitamin C is very important. The present histochemical work shows the localization of certain enzymes in different parts of the reproductive system of ten species of trematodes viz.: Neopronocephalus triangularis Mehra, 1932; Glossimetra orientalis Mehra, 1937; Orientodiscus lobatus Srivastava, 1938; Eumegacetes artemii Mehra, 1935; Ganeo tigrinus mehra et Negi, 1928; Encyclometra caudata Dollfus, 1928; Thapariella udaipurensis Gupta and Sharma, 1970; Paradistomoides indicum Narain et Das, 1929; Patagifer wesleyi Verma, 1936; Proalarioides tropidonotus Vidyarthi, 1937 and indicates their functional significance. The hydrolytic enzymes (alkaline phosphatase, acid phosphatase, 5-nucleotidase and ATPase) are suggestive of their involvement in the uptake of certain nutrients, glycogen and lipoprotein being very significant among others. The four enzymes could also be detected in testes, ovary, uterus, cirrus sac and egg shell. The possible functional significance of each enzyme has been discussed.

Risk factors, subtypes and outcome of ischaemic stroke in Kuwait--a hospital-based study.

OBJECTIVE: To report on stroke subtypes, associated risk factors and outcome in Kuwait. METHODS: The records of 62 patients (30 male, 32 female) admitted with diagnosis of stroke to Kuwait Oil Company Hospital, Kuwait, a tertiary care hospital, during a 5-year period (1995-1999), were retrospectively reviewed. RESULTS: Small artery infarction was the most common subtype and occurred in 37 subjects (59.7%); less common were atherosclerotic large artery strokes (19 patients, 30.6%) and strokes of cardio-embolic origin (6 patients, 9.7%). Identifiable risk factors or associated morbidities were hypertension (72.5%), diabetes mellitus (69.4%), ischaemic heart disease (14.5%), history of migraine (8.1%), lone atrial fibrillation (5.0%), and valvular heart disease (1.6%). The most important determinants of a deleterious 30-day outcome, as indicated by severe disability or death, were female gender, lack of use of anti-platelet drugs, presence of a large artery infarction stroke subtype, and cardio-embolic stroke. CONCLUSION: Prevalence of hypertension and diabetes is high among patients with stroke in Kuwait, with rates higher than those found in any previous reports from the Gulf region. Two unusual observations were that women had a rather high frequency of stroke, and infarction of the small artery was more common than that of the large artery. Outcome, as indicated by severe disability or death, was worse among women, elderly patients, and those with large artery atherosclerotic and cardio-embolic strokes. There is some evidence that such a deleterious outcome might be ameliorated with use of anti-platelet drugs.

Role of nuclear grooves in the diagnosis of papillary thyroid carcinoma. A quantitative assessment on fine needle aspiration smears.

Thirty-four cases of papillary thyroid carcinoma and 69 control cases consisting of 17 follicular neoplasms, 5 Hürthle cell neoplasms, 7 medullary carcinomas, 6 thyrotoxic goiters, 19 chronic lymphocytic thyroiditis cases, 3 subacute thyroiditis cases and 12 colloid goiter cases were studied for nuclear grooves. Such grooves were seen in 100% of papillary carcinoma and in 75-100% of other thyroid disorders, but their number was strikingly higher in papillary carcinoma. A quantitative assessment for nuclear grooves was made based on counting 500 follicular cells in hematoxylin and eosin (H&E)-stained and May-Grünwald-Giemsa (MGG)-stained smears. In H&E-stained smears of papillary carcinoma the number of cells with nuclear grooves (227.3 +/- 99.96 SD) was significantly higher as compared to other thyroid disorders (P < .01 to < .001). Eighty-eight percent of papillary carcinoma had nuclear grooves in > or = 20% tumor cells, whereas none of the other thyroid diseases exceeded this level. In MGG-stained smears the number of cells with nuclear grooves (40.7 +/- 32.83 SD) was also significantly higher as compared to other thyroid disorders (P < .05 to < .001). Of papillary carcinomas, 67.6% had > or = 4% cells with nuclear grooves, whereas 0-40% of other thyroid diseases exceeded this level. Nuclear grooves were significantly higher in H&E-stained smears of papillary carcinoma as compared to MGG-stained smears (P < .001). Based on this objective assessment, nuclear grooves were a useful criterion in the diagnosis of papillary thyroid carcinoma in H&E-stained smears but were not as reliable in MGG-stained smears.
