Evaluation of a short course on diabetology for practising doctors.

A short course on Diabetology, attended by 83 doctors was evaluated. The doctors were divided into three groups. (Group I--basic qualification MBBS, Group II--MD in medicine or allied subject, Group III--Diploma in Diabetes Mellitus). The mean age group of all three groups were comparable. Pre-course evaluation of their knowledge of diabetes showed the best performance in Group III and poorest in Group I. Post-course evaluation showed significant improvement only in Group I and II. Maximal improvement in performance was seen in Group II. Mean time since passing the last professional examination was 14.8, 12.6 and 1.0 year respectively. The performance was not linked to time since passing the last examination. 14.5% of doctors were from a rural or semiurban setting. The precourse performance of rural doctors in the MD group was significantly poorer, but their post course performance was as good as the others. All doctors from rural or semiurban areas improved their performance postcourse, compared to 84% in the urban group. 74% of doctors had not attended any post graduate course after their basic degree. Their performance did not differ significantly from those who had attended such courses. 44.6% were Consultants, 26.6% were general practitioners, 12.0% were attached to institutions, 10.8% were in government service or armed forces and 6% were attached to teaching hospitals. The performance of the doctors was not linked to the type of practice. The doctors attending the course felt that the audiovisual presentation needed improvement.

Carotid sinus syndrome associated with carcinoma of the pyriform fossa.

A patient who developed syncope due to carotid sinus syndrome is described. The patient was suffering from carcinoma of the pyriform fossa for the past one year and received radiotherapy in the region of the neck for the same. Demand pacing was ineffective in alleviating syncopal episodes. The patient responded to oral administration of an anticholinergic (belladonna) and a sympathomimectic agent (orciprenaline).

Biguanide-induced lactic acidosis.

Phenformin-induced lactic acidosis has been thought to be rare in India due to a high carbohydrate intake, use of suboptimal doses of phenformin and a lesser prevalence of alcoholism, as compared to Western countries. We studied the blood lactate levels of 31 non-insulin dependent diabetics (Group A) before and after treatment with phenformin, 75 mg/day for 4 weeks. Blood lactate rose significantly after treatment (mean +/- SEM 16.6 +/- 1.2 mg/dl to 30.7 +/- 2.2; p less than 0.01). Seven patients from this group had blood lactic acid level greater than 72 mg/dl. Six of these patients were restudied off treatment and after 4 weeks of phenformin therapy. The arterial blood pH, pCO2, pO2 and bicarbonate remained unchanged on treatment although a significant rise in blood lactic acid was reconfirmed in these 6 patients. Another group of 12 patients on phenformin for more than six months had significantly lower blood lactate levels as compared to group A (mean +/- SEM 20.2 +/- 1.8 mg/dl vs 30.7 +/- 2.2 mg/dl; p less than 0.01) indicating the possibility of a process of adaptation on prolonged treatment. This possibility was confirmed by a serial follow-up study of 11 patients for a 6 month period on phenformin therapy. A case of biguanide-induced lactic acidosis diagnosed and treated by us is described.

Effect of nutritional counseling on the blood glucose and nutritional knowledge of diabetic subjects.

The nutritional knowledge and control of diabetes was assessed in 43 nonketosis-prone diabetic subjects. Patients were semiliterate or illiterate. They were exposed to a 1-h nutritional counseling program in groups of three to five. The nutritional counseling program was highly simplified and emphasized only a few important aspects of diabetic diet. Patients' nutritional knowledge improved significantly after nutritional counseling. The control of diabetes also improved significantly in those patients in whom control had been inadequate.
