A man suffering from actinic reticuloid for 2 years showed highly abnormal light sensitivity over a broad action spectrum. He has been successfully treated with daily whole-body topical applications of mechlorethamine, initially for 4 weeks and after a 2-month interruption, for 3 weeks. Gauzes moistened with the same solution were placed over lichenified areas for 10-15 min. His skin became normal pale and the lichenification decreased. After treatment his tolerance for daylight increased.
30 patients with totally 178 toenails infected with Trichophyton rubrum were randomly treated with ketoconazole alone for 4 months (group A) or in combination with chemical nail avulsion (group B). Of the 14 patients in group A who completed the treatment, 4 (28%) were cured 6 months later, compared to 8 (53%) of 15 patients in group B. In 4 cases, transient elevated hepatofunction enzymes occurred. Gastrointestinal disturbances caused withdrawal in 1 case.
Multiple sensitivity to metals is often seen in humans. This may be due to cross-reactivity or to multiple sensitization. The pattern of cross-reactivity to some metal compounds was studied, using the guinea pig maximization test method. Animals were induced with K2Cr2O7 and CoCl2, respectively, and then challenged with K2Cr2O7, CoCl2, NiSO4, PdCl2 and RhCl3. No simultaneous reactivity was recorded. This supports the view that simultaneous reactivity in patients to nickel-cobalt and to chromate-cobalt is due to multiple exposure and sensitization, and not to cross-reactivity. The purity of the test compounds was analysed.
A 39-year-old Norwegian seaman developed penile ulcerations after sexual contact overseas. The diagnosis of syphilitic chancre and of chancroid was confirmed. The ulcers healed after combined treatment with benzathine penicillin and trimethoprim-sulfamethoxazol.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
