A study of serum fibrinolytic activity in erythema nodosum leprosum (ENL).

Fibrinolytic activity was studied in 31 patients of leprosy and 10 healthy controls. Fibrinolytic activity was found to be significantly decreased in patients with erythema nodosum leprosum, compared to those with uncomplicated lepromatous leprosy, who in turn showed lowered activity compared to patients with tuberculoid form of leprosy and controls. The severity of ENL correlated very well with decrease in fibrinolytic activity. Fibrinolytic activity was improved to levels obtained in uncomplicated lepromatous leprosy after the subsidence of reaction. So it would seem reasonable to suggest that estimation of fibrinolytic activity provides a reliable criteria to quantitate the severity of erythema nodosum leprosum.

Diazepam withdrawal syndrome: its prolonged and changing nature.

The diazepam withdrawal syndrome was studied in 10 patients who had abused the drug for 3 to 14 years. In the previous 6 months their consumption of diazepam had ranged from 60 to 120 mg daily; none had used other drugs during this period. The withdrawal period lasted about 6 weeks. The intensity of the symptoms and signs was high initially, fell during the first 2 weeks, then rose again in the third week, before finally declining. Three groups of symptoms and signs were identified. Group A symptoms occurred throughout withdrawal and included tremor, anorexia, insomnia and myoclonus. Group B symptoms and signs were largely confined to the first 10 days and were those of a toxic psychosis. Group C symptoms reached a peak in the third and fourth weeks of withdrawal and were characterized by sense perceptions that were either heightened or lowered. The symptom groups, the presence of tremor and myoclonus, and the relief of symptoms by a test dose permit diazepam withdrawal to be distinguished from anxiety. The biphasic course of the symptoms is probably related to the pharmacokinetics of diazepam.

Protective role of trace metals in lead intoxication.

Protective effect of copper (Cu), zinc (Zn) or cobalt (Co) against lead (Pb) toxicity in rats was investigated. Trace metal administration together with Pb decreased the hepatic and renal uptake of lead and reduced the Pb-induced inhibition of blood delta-aminolevulinic acid dehydratase (delta-ALAD) activity. The hepatic uptake of Zn or Co was also increased in animals administered Pb and Zn or Pb and Co, respectively. However, no significant difference could be observed between the protective effects of three essential trace metals examined against lead toxicity.

Flow cytometric measurement of nuclear DNA content variations as a potential in vivo mutagenicity test.

Mutagen-induced variations of the cellular DNA content have been studied in mouse bone marrow cells in vivo using high resolution flow cytometric techniques. During the first days after a single injection of the chemical mutagen cyclophosphamide an increased coefficient of variation in the G1 peak of the flow histograms was observed. The magnitude and duration of this effect were dose-dependent. The reproducibility of the measurements was high, indicating that individual variability between animals and instrumental dispersion is small. The results demonstrate that on the basis of the flow cytometric measurement of cellular DNA content, a short-term in vivo test for mutagenicity can be established which is much faster than conventional cytogenetic methods.

Septic and aseptic olecranon bursitis in patients on maintenance hemodialysis.

Over a period of four years, seven of 110 maintenance hemodialysis patients developed olecranon bursitis. In all patients it appeared in the arm on which AV access was constructed but one patient also had bilateral bursitis. None of the patients gave a history of trauma or gout. Despite similar clinical presentation, culture of bursal aspirate demonstrated septic bursitis in two patients. (One diabetic, the other on steroids). Sustained pressure on the olecranon bursa during maintenance hemodialysis and/or milk trauma in the anticoagulated state may be responsible for the lesion. Infection can occur in susceptible individuals despite no visible skin infection. Local steroid instillation and patient education to avoid putting pressure on bursa during dialysis was effective therapy in the aseptic group. Multiple aspirations and antibiotics were necessary in the septic group.

Applicability of Ridley-Jopling scale in clinical practice.

27 cases (90%) out of 30 cases studied could be graded clinically exact points of the scale. Out of the rest of 3 cases (10%); 2 cases (6.6%) required in between points of the scale. 20 cases (66.66%) out of the 30 cases studied histologically could be graded at exact points of the scale. 3 cases (10%) required further histological subgrading. Final clinico-histopathological clubbing was possible in 66.66% of cases. Disparity was observed at BT and BL points and cent percent parity was obtained at polar ends. Patients presenting with macular or early infiltrative lesions at BT and BL points showed an indeterminate histology.
