[Primary headache in childhood and adolescence. The association between changes in family interaction patterns and therapy success--a pilot study].

INTRODUCTION: Family interaction patterns are often involved in diseases and disorders in childhood and adolescence in complex ways (e.g in their development, maintenance and cure). The present study deals with the role of family factors in success in a pediatric headache therapy consisting of group hypnotherapy and systemic family consultation. METHODS: A sample of 12 outpatients, aged 9-15 years and balanced in sex, is investigated. Patients were diagnosed by IHS-criteria. Global symptom strain was measured by numeric rating scale (NRS) at pre-appointment and at 9-months follow-up appointment. Also family interaction patterns associated with the occurrence of headache symptoms were measured by content analysis. RESULTS: We found an association between changes in two independently assessed variables: global symptom strain and family interaction patterns. (1) When patients assessed global symptom strain as unchanged, family interaction patterns associated with headache were also assessed as unchanged by observers; (2) when patients assessed their global symptom strain as positively changed, family interaction pattern associated with headache were also assessed as positively changed by observers. CONCLUSION: These data provide empirical evidence about when to include family in treatment of pediatric headache: when rigid family interaction patterns associated with headache complicate a symptom change.

[Androgenetic alopecia in the man].

Androgenetic alopecia (AGA) occurs in approximately 40% of men at the age of 40 and 50% at 50, respectively. Especially for young men progressive hair loss can be distressing. Therefore, understanding of these patients' concerns is important for appropriate management. Current understanding of the pathophysiology of AGA mainly focuses on androgen metabolism as it affects hair growth. As a result, pharmacologic treatment has made considerable progress through the introduction of selective 5 alpha-reductase inhibition with finasteride. In placebo-controlled clinical trials in men with AGA, treatment with oral finasteride proved to be effective. Minoxidil is the only pharmacological substance for topical application with proven efficacy. So far, other treatment modalities have no proven efficacy in clinical trials, so that their use cannot be recommended. Options for advanced AGA not amenable to pharmacologic treatment are autologous hair transplantation and hair replacement, both of which have recently also made progress in terms of cosmetic appeal.

Selective specimen preparation for TEM observation of the cross-section of individual carbon nanotube/metal junctions

We present here an efficient method to prepare a transmission electron microscopy (TEM) specimen for selective observation of the cross-section of individual nanoscale structures. As a typical example, the cross-sectional TEM observation of a quasi-one-dimensional material - a nano-electronic component based on an individual carbon nanotube - is presented.

Leg ulcers in patients with myeloproliferative disorders: disease- or treatment-related?

Leg ulcers are a relatively frequent problem in patients with myeloproliferative disorders under treatment with hydroxyurea (HU). The pathogenesis is currently unknown and may be multifactorial. Concomitant arterial or venous disease may play a contributing role in the development of these wounds. Vasculitis, cryoglobulinemia and pyoderma gangrenosum should be considered if typical clinical signs are present. We report on 3 patients with myeloproliferative disorders who developed HU-induced leg ulcers and review the literature. HU-induced leg ulcers share clinical features which can help to differentiate them from leg ulcers of other etiologies: occurrence under long-term treatment with HU at a dose of at least 1 g/day, localization in the malleolar region and spontaneous healing when HU is discontinued. We conclude that differentiation between disease-related and treatment-induced leg ulcers can be difficult and may not always be possible. In HU-induced leg ulcers, cessation of the drug typically leads to wound healing.

[Erythroderma and alcohol abuse].

We report on 7 patients with chronic alcohol abuse and ichthyosiform erythroderma. Dry skin (i.e. xerosis cutis) was a striking common feature in all patients who did not present any signs of fluid depletion. Two patients had exclusively exsiccational dermatitis; three had atopic disposition and one nummular eczema of the legs. In another patient a drug allergy could be demonstrated. Xerosis cutis seems to be an important precipitating aetiologic factor for erythroderma, and may be a consequence of alcohol-induced diuresis. All patients recovered rapidly under topical treatment with emollients and low potency steroids. We propose that ichthyosiform erythroderma be added to the known skin diseases caused by chronic alcohol abuse.

The action of benzbromarone in relation to age, sex and accompanying diseases.

The uric-acid lowering effect was investigated in a group of 2220 patients. 1984 of these were employed for statistical evaluation purposes. On average, the uric acid level was reduced from 8,24 +/- 1,16 mg/100 ml to 5,32 +/- 1,265 mg/100 ml. In 82 % of all the cases, the uric acid level at the end of the treatment period was below 6,4 mg%, both in patients treated throughout with 50 mg benzbromarone (NarcaricinRmite) and in those changed over to 100 mg benzbromarone (NarcaricinR) after 1 to 3 weeks. The lowering of the uric acid levels was in no way related to hypertension, adiposity, hyperlipoproteinaemia, diabetes mellitus or age.
