Cognitive dysfunction in NIDDM: P3 event related evoked potential study.

P3 component of the endogenous cerebral evoked response is a sophisticated, objective and quantitative approach to assess higher functions of the brain. This test was employed using auditory 'odd ball' paradigm to assess cognitive functions in thirty non insulin dependent diabetic patients (NIDDM) aged 43.6 +/- 9 yrs with poor blood glucose control. (HbAlc. 9.9 +/- 1.0%). The peak latencies of N2, P3 components of event related evoked potentials obtained in these patients were compared with 30 age and sex matched non diabetic healthy controls. Latencies of these potentials were: N2 = 248.0 +/- 36.3, P3 = 391.6 +/- 49.9 msec in NIDDM as compared to 220.6 +/- 26.4, 326.2 +/- 26.8 msec in controls and were highly significant (P < 0.001). The duration of disease, blood glucose level or the physical parameters of height, weight and blood pressure did not show any correlation with N2 or P3 latencies or amplitude. These findings provide an electrophysiological evidence of delayed cognition in poorly controlled NIDDM cases.

Leukemoid reaction in amoebic liver abscess.

A case of amoebic liver abscess with leukemoid reaction is described. This patient also had jaundice as the presenting feature. Therapy with metronidazole resulted in improved general condition and both blood picture and liver function tests also became normal.

Fat and oil inhibit phosphine release from aluminium phosphide--its clinical implication.

Poisoning by suicidal or accidental ingestion of aluminium phosphide (AlP) is a frequent medical emergency seen all over the world. AlP, a grain fumigant and rodenticide, on exposure to moisture, liberates highly toxic gas, phosphine. The rapidly inhibits mitochondrial respiration and has cytotoxic action. No specific antidote is known against it till date and prognosis depends much on dose and time lag between AlP ingestion and the stomach wash in the hospital (critical period). Physicochemical properties of AlP and nonmiscibility of fat and water promoted us to study the effect of different fats and oils as possible antidotes to inhibit phosphine liberation. In vitro experiments revealed that vegetable oils and liquid paraffin were much more effective than butter and ghee in inhibiting release of phosphine from AlP. These findings may have significant clinical implication.

Aetiological profile of overt hypothyroidism in Indian population.

We analysed the aetiology of hypothyroidism in 144 patients. In these hospital referral data, thyroid surgery and decompensated iodine deficiency were the major known causes of hypothyroidism (19.5% and 15.3% respectively), while in the majority of patients (45.14%) the aetiology was obscure. The idiopathic group had patients who were significantly younger (p less than 0.01), showed a gland size between 2 and 3 SD ranges in significantly higher preponderance (p less than 0.05), and presented with generally higher prevalence rates of signs and symptoms; however, only menstrual disturbances (p less than 0.01), loss/reduced appetite (p less than 0.01) and dry/thickened hair (p less than 0.25) reached statistical significance. Since hypothyroidism has definite and substantial morbidity, these results are of importance to public health and medical personnel for a Bayesian approach to the aetiological diagnosis of hypothyroidism and for ordering specific confirmatory laboratory investigations.
