BACKGROUND: Many traditional treatments have been recommended in the alternative system of medicine for treatment of diabetes mellitus; however, the mechanism of most of the herbals used has not been defined. AIMS: This study was carried out to clarify the effect of fenugreek, garlic and onion, recommended in Persian folklore medicine as beneficial in the treatment of diabetes, on blood glucose and their possible effect on pancreatic tissue. METHODS AND MATERIAL: Diabetes mellitus was induced in 20 out of 25 adult male albino rats, using intraperitoneal injection of 185 mg/kg BW alloxan. The diabetic rats were divided into four groups, three of which were fed a diet containing 12.5% BW Allium sativum (garlic), Allium cepa (onion) or Trigonella foenum-graecum (fenugreek) for 15 days. The fourth group (positive control) received an ordinary diet. The remaining non-diabetic rats (negative control group) received neither alloxan nor the mentioned plants. Following consumption of plants, blood glucose was measured every day and on the last day the pancreas were removed and stained with H&E and Gomeri aldehyde fuchsin (GAF). Morphology of the pancreatic sections and the following morphometric factors were studied: volume density of B cells, volume density of islets, percent of B cells, number of islets per square millimeter, average area of islets and average volume density of B cell in whole pancreas. STATISTICAL ANALYSIS USED: One-way Analysis of Variance (ANOVA) test and Duncan's multiple range tests were used to evaluate the data. RESULTS AND CONCLUSION: The results of this study indicate that only garlic was able to reduce blood glucose significantly compared with the control group (P<0.05). In the control positive group all the mentioned morphometric factors were significantly changed in comparison with the control negative (normal health) group, but the same did not show significant change between treated and untreated diabetics.

Rabson-Mendenhall syndrome is characterized by growth retardation, dysmorphisms, lack of subcutaneous fat, acanthosis nigricans, enlarged genitalia, hirsutism, premature and dysplastic dentition, coarse facial features, paradoxical fasting hypoglycemia and post-prandial hyperglycemia, extreme hyperinsulinemia and pineal hyperplasia. We describe a six-month-old female child with physical features suggestive of the Rabson-Mendenhall syndrome. The child also had medullary nephrocalcinosis.

BACKGROUND: The physiological changes in the thyroid gland during pregnancy are well understood but only a few reports provide information about thyroid function in complicated pregnancies. AIMS: The present study evaluates thyroid hormonal levels in cases of preeclampsia in the third trimester of pregnancy. SETTINGS & DESIGN: A case-control study was conducted in the antenatal clinic of a public hospital of Delhi. METHOD & MATERIALS: Thyroid hormones, namely triiodothyronine (Free T3), thyroxine (Free T4) and thyroid stimulating hormone (TSH) were evaluated at the time of diagnosis of preeclampsia in 82 pregnant women and equal number of matched controls. STATISTICAL ANALYSIS: The demographic data and hormone levels were analyzed using students' t test, Mann-Whitney test and chi-square test. Pearson two-tailed analysis was used for correlation. RESULTS: Mean TSH levels were significantly higher in preeclamptic group as compared to controls (p<0.001). However, mean values of thyroid hormones were in the normal range. Approximately 40% preeclamptic women had TSH titres > 5mIU/ml in the study group as compared to 12.2% in the controls. Approximately 76.7% of 43 pregnant women with abnormal TSH titres and 40% of 121 pregnant women with normal TSH titres belonged to the study group (p< 0.001). The odd ratio corresponding to TSH titres > 5mIU/ml in preeclamptic women was 4.85 (95% CI 2.19-10.74). CONCLUSIONS: Mean serum TSH levels were significantly increased without concomitant changes in free T3 and T4, in preeclampsia compared to normal pregnancy. Abnormal TSH titres might be associated with a risk for occurrence of preeclampsia.

BACKGROUND: A Study on Vataliya Prajapati was published earlier but heterozygous females were not identified. AIMS: To compare incidence of glucose-6-phosphate dehydrogenase (G6PD) deficiency in random and unrelated subjects, present and previous study and as per their original habitat. Incidence of heterozygous deficiency and clinical implication of deficiency was also determined. SETTINGS AND DESIGN: Camps were organized in Katargaon and Amroli regions. Blood specimens, with relevant demographic information, were collected from those who attended the camp. METHODS AND MATERIAL: A total of 1644 random blood samples were collected from 404 families participating in the camps. Nitroblue tetrazolium dye test was used for G6PD deficiency screening and quantitative assay for measurement of G6PD enzyme activity. STATISTICAL ANALYSIS USED: 2 test was used to evaluate significance and mean values were compared by the Student's "t" test. RESULTS: Incidence of G6PD deficiency was found as 22% among all the random samples tested. However, the G6PD deficiency among unrelated members was 27.9% in males and 12.4% (P<0.001,df 1). The 13.9% of the females with heterozygous G6PD deficient status, together with the homozygous deficient phenotype makes the incidence comparable with males. Incidence of deficiency was comparable with previous study, in Katargam and Amroli and in Amerli and Bhavganar districts. Deficient subjects had mild anemia and hemolytic crisis rarely occurred. CONCLUSION: Vataliya Prajapatis have high incidence of G6PD deficiency without severe chronic hemolytic anemia. However before prescribing medicines physician should know the G6PD status of a Vataliya Prajapati patient.

In recent years there have been a number of malpractice suits based on lack of consent or inadequate consent from the patient for the procedure used in treatment. This is a particularly dangerous suit for the doctor since the burden of proof lies on the doctor. Furthermore since the suit is based on intentional assault, some insurance policies do not cover the doctor for his liability. The common meaning of consent is permission, whereas the law perceives it as a contract i.e. an agreement enforceable by law. So a doctor needs to understand the legal basis of consent rather than the common meaning of it. The present article aims to discuss the various legal aspects of consent as viewed in the Indian law.
