Background & Objectives: Low serum folate level is often reported as an adverse drug sequela of long term phenytoin usage seen with prolonged duration of phenytoin therapy. There is no previous study to prospectively track the serum folate level with usage of phenytoin, which is the objective of this study. Methods: Twenty-fi ve patients between the ages of 18-50 years diagnosed to have epilepsy and planning to start phenytoin were recruited in this study. Assessment of serum folic acid was done by chemiluminiscent method prior to the start of phenytoin and after 6 months of treatment. The serum folate level of 10 age and sex matched healthy control was also taken. Results: The average serum folate level was 7.48 + 2.04 ng/mL prior to the start of phenytoin therapy, which fell to 3.9 + 1.95 ng/mL after 6-month of phenytoin therapy (p-value <0.001). The average serum folate level for the age and sex matched 10 control samples was 14.46 + 2.81 ng/mL. Conclusion: A signifi cant fall of serum folic acid levels is seen in epilepsy patients after 6 months treatment with phenytoin.

Background: The role of oxygen free radicals in the initiation, promotion and progression of carcinogenesis and the protective role of anti-oxidant defenses have been the subject of much speculation in the recent past with confl icting reports in the literature. Objectives: The aim of this study was to measure the concentration/levels of serum total proteins, albumin and advanced oxidation protein products as markers of oxidative stress in sera of patients with an oral pre-cancerous lesion and frank oral cancer. Materials and methods: The study consisted of sera analysis of 30 new patients of histologically proven well-differentiated, oral squamous cell carcinoma and 10 patients, clinically diagnosed with a potentially malignant epithelial lesion, speckled leukoplakia, aged between 40 to 60 years, in addition to 25 healthy controls. One way analyses of variance were used to test the difference between groups. The normality of data was checked before the statistical analysis was performed. Results: The study revealed variations in sera levels of albumin and advanced oxidation protein products to be statistically signifi cant (p < 0.001). Conclusion: The results obtained emphasize the need for more studies with larger sample sizes to be conducted before a conclusive role could be drawn in favour of sera levels of total protein, albumin and advanced oxidation protein products as markers of diagnostic signifi cance and of the transition from the various oral pre-cancerous lesions and conditions into frank oral cancers.

OBJECTIVES: To measure the prevalence of behavioural risk factors for obesity among urban adolescent school children in Chennai, India. METHODS: This study was performed as a cross-sectional study using a World Health Organization-designed Global School-based Student Health Survey questionnaire (modified for India) among adolescent school children studying in 30 randomly selected secondary and higher secondary schools in Chennai city. 1842 adolescents studying in the VIII to XII standards were randomly selected for the study. RESULTS: In the present study, 40.7% of the students ate fruit one or more times per day and 74.5% of the students ate vegetables one or more times per day. Nearly 20% of the students ate fast food items on 4 to 7 days during the previous week. Among the students, 30.4% watched television for more than two hours per day. Nearly 68% of the girls and 22% of the boys did not participate in outdoor sports activities. When the pattern of physical activity of the students was assessed, it was observed that 15.6% were inactive, 43.4% were minimally active, and the remaining 41.0% belonged to the category of health enhancing physical activity. Among the students, 6.2% were overweight and 5.2% were obese. CONCLUSIONS: The prevalence of risk factors for obesity was quite high among the adolescents. This study also showed that a great proportion of overweight/obese adolescents had a correct perception of their body weight and they were making efforts to modify risk factors such as television viewing, computer use, a sedentary lifestyle, and unhealthy dietary habits.

A peculiar liver was found in an adult male cadaver during a dissection class for undergraduate medical students. The quadrate lobe and fissure for the ligamentum teres were totally absent. Thus, the cystic notch on the inferior border was very broad and deep, and the fundus and body of the gall bladder popped out through this notch. The cystic duct terminated into the right hepatic duct at the porta hepatis instead of terminating into the common hepatic duct. Awareness of variations of the lobes and fissures may minimize a misdiagnosis of liver problems. The aim of the current study was to alert radiologists and surgeons about possible variations in the external appearance and anomalies of the lobes and fissures of the liver.

OBJECTIVE: To evaluate the effect of hepatic insulin gene therapy on diabetic enteric neuropathy. METHODS: Mice were randomly allocated into 3 groups: a normal control group, a diabetic group, and a diabetic gene therapy group. Diabetes were induced by penial vein injection of streptozocin (STZ). The gene therapy group received hepatic insulin gene therapy while the other 2 groups only received an empty virus expressing green fluorescent protein. Random blood glucose, body weight growth, gastric emptying, total bowel length, absolute and relative bowel transit, electric field stimulation of colon smooth muscle, colon nuclei staining and counting were measured. RESULTS: We successully established a mouse model of diabetic enteric neuropathy which manifests as: 8 weeks of continuous hyperglycemia,increased total bowel length, decreased relative bowel transit, impaired colon smooth muscle relaxation and loss of inhibitory neurons in colon. Through gene therapy, the above indexes were normalized or ameliorated, suggesting hepatic insulin gene therapy is capable of preventing diabetic enteric neuropathy. CONCLUSION Hepatic insulin gene therapy can prevent STZ induced diabetic enteric neuropathy.
