RESUMEN

BACKGROUND: Female sex has been reported as a predictor for treatment discontinuation with biological therapies for psoriasis, although reasons remain unclear. It can be hypothesized that lower satisfaction with biological treatment in women might add to the lower drug survival rates. OBJECTIVES: To identify possible differences in satisfaction with biological treatment between female and male patients using the Treatment Satisfaction Questionnaire for Medication (TSQM). METHODS: Data of psoriasis patients treated with biologics were obtained from the prospective, multicentre, daily-practice BioCAPTURE registry. Longitudinal TSQM data were analysed by linear mixed models. Relevant patient characteristics were incorporated as possible confounding factors. Post hoc analysis of adverse events was performed in order to investigate differences between sexes. RESULTS: We included 315 patients with 396 corresponding treatment episodes (137 adalimumab, 90 etanercept, 137 ustekinumab, 24 secukinumab and 8 infliximab). Almost forty per cent of the patients were female. Women had significantly lower baseline PASI scores (P = 0.01). Longitudinal analyses demonstrated lower TSQM scores for 'side-effects' (P = 0.05) and 'global satisfaction' (P = 0.01) in female patients compared with male patients over 1 year of treatment. Women reported more relevant adverse events in the context of biologic treatment compared to men (rate ratio 1.79; P < 0.001), with more fungal (rate ratio 2.20; P = 0.001) and herpes simplex infections (rate ratio 3.25; P = 0.005). CONCLUSIONS: This study provides a prospective, longitudinal analysis of treatment satisfaction with biologics in female and male patients with psoriasis. Women were slightly less satisfied with treatment regarding side-effects and global satisfaction. Differences in treatment satisfaction and side-effects might add to the fact that women discontinue biological treatments more often.

RESUMEN

In four patients, two women aged 40 and 42 years and two men aged 49 and 37 years, type I allergy to Ficus benjamina was established. Two patients had been sensitized by contact with these pot plants at their homes. The other two patients were plant growers. F. benjamina is a non-flowering, currently very popular pot plant to be found in both private houses and public buildings. The symptoms comprise itching and swelling of the eyelids, tears, running nose, wheezing and dyspnoea. In one plant grower contact urticaria progressing to dermatitis of the hand was the main symptom. Only one patient had a clear-cut atopy. Both plant growers showed a cross-allergy to other Ficus species. Two patients had a cross-allergy to latex and the associated cluster of tropical fruit (banana, kiwi, avocado, and chestnut). Removal of the ficus plants from the homes and change to another crop or to another occupation completely resolved the complaints of these patients.

RESUMEN

We report a 6-month-old boy with an unusual form of cutaneous histiocytosis. The lesions were noticed shortly after birth, and there was no evidence of systemic disease. This histiocytic disorder could not be classified according to the Histiocyte Society classification, and was therefore designated an 'unclassified' group II histiocytic disorder. The clinical picture was characterized by dark-red papulonodules with a tendency to coalesce into plaques. Histologically, the infiltrate was characterized by non-epidermotropic histiocytes showing varying degrees of differentiation, eosinophils and lymphocytes, and by the absence of foamy cells and Touton giant cells. As a most conspicuous feature, electron microscopic examination revealed laminated dense bodies, whereas Birbeck granules and comma-shaped bodies were absent. This further distinguished this uncommon variant from the well-known class II histiocytoses. During a 6-month follow-up period all the lesions showed marked regression.

RESUMEN

13 patients allergic to the cationic emulsifier oleamidopropyl dimethylamine were tested with a series of related amide-amine type surfactants in order to investigate its cross-reaction pattern. With 1 exception, all patients reacted to at least 4 of the test materials. Most reactions were observed to ricinoleamidopropyl dimethylamine lactate and tallowamidopropyl dimethylamine (11 patients, 85%); 9 patients (of 12 tested, 75%) reacted to lauramidopropyl dimethylamine and 6 (46%) to myristamidopropyl dimethylamine. A certain pattern of cross-reactivity was recognised.

RESUMEN

Complicated infections caused by penicillinase-producing Neisseria gonorrhoeae (PPNG) are uncommon. Of two patients with prostatitis due to PPNG, one was cured by cefoxitin followed by co-trimoxazole, the other by co-trimoxazole alone. The potential of co-trimoxazole in the treatment of PPNG-prostatitis looks promising.
