PROBLEM: Abstract: Using a computed video image analysis system, the staining intensity for both neurone specific enolase (NSE) and S100 protein was measured in sections from 19 malignant melanomas and 16 benign melanocytic lesions. The results of this study confirm previous reports that NSE and S100 protein are useful markers for malignant melanoma. NSE staining intensity in the cases of malignant melanoma was significantly higher than that in benign naevi (p = 0.011). Intensity of staining for S100 protein was not significantly higher in the malignant melanomas. There was, however, a significant S100 gradient when comparing superficial and deep intradermal portions of these tumours (p = 0.003). This feature was not seen in benign naevi. The greatest intensity of S100 protein staining was found in the deeper portions of the malignant melanomas. This gradient difference was not seen with staining for NSE. Although it seems that the overall intensity of staining for NSE is more effective in differentiating between benign and malignant lesions, the difference in staining intensity between the superficial and deep portions of the tumour may be the better indicator of adverse behaviour in lesions in which the diagnosis of malignancy is uncertain.

SOLUTION: Measuring S100 protein and neurone specific enolase in melanocytic tumours using video image analysis.

PROBLEM: Abstract: In six depressed epileptic patients stabilised on carbamazepine therapy, addition of the antidepressant agent viloxazine (300 mg/day for three weeks) induced a marked (average 55%) increase in steady-state plasma carbamazepine concentration. The concentration of the active metabolite carbamazepine-10,11-epoxide also increased during viloxazine therapy, but to a lesser extent (16%). In three patients, these effects were associated with symptoms of carbamazepine intoxication, which regressed rapidly when plasma carbamazepine and carbamazepine-10,11-epoxide levels returned to baseline values after discontinuation of viloxazine. In a seventh patient, viloxazine had to be discontinued after only two weeks because of severe side effects associated with a striking elevation of carbamazepine and carbamazepine 10,11-epoxide levels (by 197% and 137% respectively). Although viloxazine appears to be one of the few antidepressants which can be used safely in patients with epilepsy these results indicate that the drug should be prescribed with great caution in subjects treated with carbamazepine. The mechanism of the interaction probably involves inhibition of the metabolism of both carbamazepine and its active epoxide metabolite.

SOLUTION: Carbamazepine-viloxazine interaction in patients with epilepsy.

PROBLEM: Abstract: Cell-mediated and humoral immune responses were assessed in 50 patients with oral submucous fibrosis (OSMF) and the results were compared with those of 50 patients with oral-leukoplakia, 50 oral cancer patients, and 50 normal healthy adult controls. The number of high-affinity rosette-forming cells (HARFC) was found to be significantly decreased in OSMF and oral cancer, whereas the number of total rosette-forming cells (TRFC) remained unaltered. Levels of serum IgA, IgD, and IgE were found to be elevated both in OSMF and oral cancer. Immunologic derangements were found to be more pronounced in oral cancer than in OSMF. The enumeration of HARFC along with the estimation of serum levels of IgA, IgD, and IgE indicates that OSMF can be an intermediary stage in the malignant transformation of a normal cell, and that these parameters may serve as markers for the early detection of oral cancer.

SOLUTION:
Cell mediated and humoral immune responses in oral submucous fibrosis.
