Topical minoxidil has shown some promise for the treatment of male-pattern alopecia and alopecia areata. Clinical trials suggest that careful patient selection and appropriate drug formulation are both important factors to maximize efficacy. Side effects attributable to topical minoxidil appear to consist almost entirely of cutaneous reactions in patients who have been studied thus far, i.e., patients without hypertension or cardiovascular disease. The mechanism of minoxidil-induced hair regrowth is not fully understood, but it may involve a synergistic effect of minoxidil on a variety of cell types.

Quinidine-induced lichenoid photodermatitis was definitely isolated by Berger and Sesody in 1982. We had an opportunity to observe 4 cases of this striking clinical condition and encountered some particularities. Our patients (2 men and 2 women) were 60, 64, 81 and 68 years old respectively. All had a previous cardiovascular history; diabetes was also present in patient No. 2, and hypertension in patient No. 4. All patients were taking other drugs. The first patient presented with a 4-year old lichenoid eruption on the hands, associated with some degree of follicular keratosis. The second and third patients had a mixture of mainly lichenoid lesions on sun-exposed areas, but eczematous and desquamative lesions were also encountered. The fourth patient had typical lichenoid photodermatitis with occasional bullae on the arms and legs. In all patients the disease appeared or worsened in the Summer. It disappeared rapidly in 3 cases upon withdrawal of quinidine (patients No. 1 and 2) or hydroquinidine (patient No. 3), but it lasted longer in patient No. 4, with pigmented sequelae. Histological examination of the skin was consistent with a lichenoid eruption in all cases. However, an immunopathological study revealed a pemphigoid-like pattern in patients No. 1 and 2, and ovoid bodies more suggestive of lichen planus in patient No. 4. Photobiology was not performed. A review of the literature showed that the terms "lichen planus", "lichenoid", "lichenification" or "violaceus hue" were frequently encountered, and we suggest quinidine as one of the most common agents of lichenoid reaction.(ABSTRACT TRUNCATED AT 250 WORDS)

Of 149 subjects with androgenetic alopecia, 102 completed 1 year of a double-blind, randomized study comparing 2% minoxidil and 3% minoxidil solutions for safety and efficacy. One third of the subjects used a vehicle placebo for the first 4 months and then switched to 3% minoxidil. At 12 months the 2% minoxidil group switched to a 3% solution. During months 5 to 12 a steady increase in terminal hair counts occurred to an equal degree within the 2% and 3% minoxidil groups and the 3% treatment group switched from placebo. Total hair counts at 12 months increased from a baseline mean of 63.5 to 180.6 in the 2% treatment group, from 61.0 to 179.9 in the 3% group, and from 65.0 to 191.1 in the placebo to 3% crossover group. Although all 102 subjects completing 12 months of the study thought that visible hair growth had resulted, 89 were considered by the investigators to have visible growth. Dense hair growth, defined as hair long enough to cut or comb, was present in 48 subjects by their own evaluation and in 33 subjects by investigator evaluation. There were no serious side effects. Two instances of allergic contact dermatitis and four of pruritus were attributed to use of the drug. Two individuals complained of impotence, which disappeared within a few days of discontinuation of topical minoxidil. This effect has not been reported during the use of minoxidil in its oral form (Loniten) for the treatment of hypertension.(ABSTRACT TRUNCATED AT 250 WORDS)

Eight deaths that occurred during Upjohn-sponsored clinical trials of topical minoxidil and two deaths in subjects who used extemporaneous formulations of the drug are summarized. Of the eight patients in clinical trials, five had cardiovascular abnormalities and two had acquired immunodeficiency syndrome-related pneumonia. One patient died of a self-inflicted gunshot wound. One of the subjects who was using extemporaneous topical minoxidil had hypertension and arteriosclerotic disease and the other died of a myocardial infarction. There is little likelihood of significant adverse effects attributable to topical minoxidil because of its low systemic absorption. The evidence suggests that these deaths were the result of causes other than use of the drug.

Elevated blood pressure is a major cause of perioperative bleeding and postoperative hematoma. Seventy-five patients scheduled for dermatologic surgical procedures were prospectively asked if they were aware of any personal history of hypertension. If patient response alone is relied on as a preoperative screen for hypertension, over half of the individuals affected with this disease will be missed. Epinephrine-containing local anesthetics were found not to increase blood pressure in doses commonly employed by dermatologists; in fact, they lowered blood pressure in hypertensive individuals.

We report 3 cases of severe syphilitic neuro-meningitis during the secondary stage: acute transverse dorsal myelitis with permanent paraplegia in a 17 year old teenager (case no. 1), uveo-meningitis with intracranial hypertension and diminished vision in a 52 year old woman (case no. 2), lower medulla lesion in a 46 year old man (case no. 3). The diagnosis was based upon highly positive serological tests for syphilis, associated with a compatible clinical context and meningitis in CSF specimens. Treatment was successful in cases nos. 2 and 3, unsuccessful in case no. 1 due to the irreversible character of the medullar lesions. Based on these 3 cases, the following points are discussed: the relatively atypical clinical character in the current context, the difficulties of the diagnosis, and the treatment regimens recommended for neurological syphilis. Despite the rarity of such cases, their extreme severity early in the secondary stage strongly implies the necessity for prevention by detecting and treating early syphilis. Attention is drawn upon the importance of doing serological tests for syphilis when presented with any atypical neurological situation.

A patient with hypertension and chronic renal failure of an undetermined cause who was undergoing hemodialysis developed bilateral crusted, focally eroded plaques on her breasts. A biopsy specimen of the lesional skin revealed typical histologic changes of pseudoxanthoma elasticum, with epidermal perforation. A biopsy specimen of lesion-free skin revealed characteristics typical of pseudoxanthoma elasticum. Perforating pseudoxanthoma elasticum should be added to the growing list of cutaneous disorders that occur in patients with chronic renal failure who are undergoing hemodialysis.

Three cases of pyoderma gangraenosum were associated with Takayasu arteritis (pulseless disease), characterized by disappearance of pulse, hypertension and/or aortic insufficiency. Another 11-year-old boy, suffering from a serious congenital heart malformation, presented skin lesions of pyoderma gangraenosum. In spite or rather low incidence of association of ulcerative colitis (10.4 p. 100), Japanese cases show frequent association of cardiovascular diseases, especially Takayasu arteritis (27.1 p. 100).

A 48-year-old white woman who for 3 years had been taking hydralazine, 100 mg three times a day, propranolol, 160 mg twice a day, and chlorothiazide, 500 mg/day, for hypertension suddenly developed rapidly expanding ulcers that looked like pyoderma gangrenosum. Arthralgias, fevers, and occasional shortness of breath were also noted. A pericardial effusion was diagnosed by echocardiography. The antinuclear antibody (ANA) titer on routine mouse liver substrate was initially negative, but the ANA titer was positive (1:1,920) on human epithelioid cell substrate. Antibodies to histones and single-stranded DNA were also elevated. After discontinuing hydralazine, all signs and symptoms cleared over a 4-week period. At the time of discharge the ANA titer had decreased to 1:480.

We observed the course of development of porokeratosis stimulated by benzylhydrochlorothiazide (BHCTh) in normal-appearing skin of a patient with long-standing stable porokeratosis of Mibelli. A 72-year-old Japanese man had had porokeratosis of Mibelli for more than 50 years. During administration of BHCTh for 1 year because of his hypertension, a lichenoid drug eruption developed over the lesions of porokeratosis on the flexor aspects of his legs. Readministration of BHCTh by another physician for 6 months resulted in the occurrence of a similar drug eruption that converted into typical skin lesions of porokeratosis 8 weeks later. Serial microscopic examination suggested that BHCTh administration resulted in eosinophilic spongiosis and cornoid lamella formation, which developed into epidermal changes characteristic of porokeratosis.
