    Notes: Background Focal hyperhidrosis is a common condition mostly confined to the axillae, palms and soles. In some individuals, predominantly men, increased sweating of the forehead may be the major complaint and may interfere with the person’s quality of life. Botulinum toxin A has been shown to be a very effective treatment for focal hyperhidrosis of the axillae and palms. Objectives To assess the response in 10 men suffering from frontal hyperhidrosis treated with botulinum toxin A. Methods Botulinum toxin A Botox® was injected at multiple sites evenly distributed over the forehead (mean dose 86 mouse units) . Results The mean ± SEM amount of sweat was significantly reduced, 4 weeks after treatment, from 173·8 ± 38·6 mg min−1 to 53·7 ± 17·6 mg min−1. The effect lasted at least 5 months in nine of the 10 patients. All patients subjectively judged the treatment as very effective. Minor side-effects included painful injections and a transient weakness of forehead muscles without ptosis. Conclusions In this study, we provide evidence that botulinum toxin A is an effective and safe treatment for frontal hyperhidrosis.

    Notes: We describe a 13-year-old girl with multiple pigmented nodules and plaques arranged in a cluster in the right lumbar region, which had developed since infancy.Eleven of 15 lesions which were examined histologically were found to be Spitz naevi. The remaining four lesions were compound naevocellular naevi, and two of them showed focal dysplasia. Eight Spitz naevi were investigated immunohistologically with monoclonal antibodies against HLA-antigens and malignancy-associated melanocytic antigens which are rarely present in common naevi. Naevus cells in all lesions expressed HLA-ABC antigens, but lacked HLA-DR antigens in seven of the eight lesions. All naevi were positive for ‘constitutive’ (KG-6-56) and ‘early’ (K-i-2) markers of nacvomelanocytic cells. In five of the eight Spitz naevi, at least one of the three malignancy-associated melanocytic antigens PAL-M1, A-1-43 and A-10-33 was found.The expression of malignancy-associated antigens in multiple agminate Spitz naevi is at variance with their benign clinical course.

    Notes: Background  Hyperhidrosis (primary or secondary) is excessive sweating beyond that required to return body temperature to normal. It can be localized or generalized, commonly affecting the axillae, palms, soles or face, and can have a substantial negative effect on a patient's quality of life.Impact of disease  Objective evaluation comprising quantitative assessment (gravimetric and Minor's iodine starch test) and subjective evaluation (Dermatology Quality of Life Index and Hyperhidrosis Impact Questionnaire) allow accurate assessment of the impact of hyperhidrosis on patients.Botulinum toxin type A  Botulinum toxin type A acts by inhibiting the release of acetylcholine at the presynaptic membrane of cholinergic neurones. It has proved useful in treating a number of diseases relating to muscular dystonia and is now proving beneficial in treating hyperhidrosis. Clinical trials investigating botulinum toxin type A use in axillary and palmar hyperhidrosis show significant benefits with few side-effects reported, with a favourable impact also being seen on patient quality of life. Botulinum toxin type A injections are generally well-tolerated with beneficial results lasting from 4 to 16 months.Conclusions  Botulinum toxin type A injections are an effective and well-tolerated treatment for hyperhidrosis. This paper proposes a positioning of this treatment along with current established treatments, and highlights the role of botulinum toxin type A as a valuable therapy for the treatment of hyperhidrosis.

    Notes: Summary Schwannomas are benign solitary tumours of the peripheral nerve sheaths. The occurrence of multiple schwannomas usually implies hereditary disease. The most frequent syndrome associated with multiple schwannomas is neurofibromatosis type 2 (NF2), which is defined by bilateral vestibular schwannomas. Schwannomatosis is a distinct disease characterized by multiple pathologically proven schwannomas in the absence of vestibular schwannomas. It is not currently known if the presence of multiple schwannomas confined to a limb may represent a mosaic form of NF2 or a distinct disease, because mutation analysis of these tumours is not routinely performed. We report a 31-year-old patient who presented with multiple slowly growing subcutaneous tumours on his left arm. His family history was negative for cutaneous tumours or central nervous system disease, and he did not have additional features of NF2. Magnetic resonance tomography and ophthalmological examination excluded vestibular schwannoma and eye stigmata of NF2. After resection of three tumours, histological analysis confirmed the diagnosis of benign schwannomas. Molecular genetic analysis by temperature gradient gel electrophoresis and microsatellite marker analysis demonstrated two distinct mutations of the NF2 gene (NF2) in two different schwannomas, with concomitant loss of heterozygosity in both tumours. In contrast, neither normal skin nor peripheral blood lymphocytes revealed mutations of NF2. The clinical and molecular genetic findings suggest that the diagnosis in our patient is schwannomatosis rather than segmental NF2 because the mutations found in different tumours were not identical. The possibility of a localized predisposition for the acquisition of NF2 mutations is discussed.

    Notes: Summary Background  Botulinum toxin type A (BTX-A) has been shown to be a safe and effective treatment for primary focal hyperhidrosis. However, the effect of BTX-A therapy on quality of life (QOL) in patients with this condition has only recently begun to be studied in controlled clinical trials. Objectives  To assess the impact on QOL of BTX-A treatment in patients with bilateral primary axillary hyperhidrosis. Methods  A multicentre, randomized, double-blind, placebo-controlled trial enrolled 320 patients who exhibited persistent, bilateral, primary axillary hyperhidrosis sufficient to interfere with daily activities. These patients were treated with either 50 U BTX-A (Botox ® , Allergan, Inc., Irvine, CA, U.S.A.) or placebo in each axilla. QOL was assessed using the Hyperhidrosis Impact Questionnaire © (HHIQ) at baseline and 1, 4, 8, 12 and 16 weeks post-treatment, as well as the Medical Outcomes Trust Short Form-12 Health Survey © (SF-12) at baseline and 16 weeks post-treatment. Results  At baseline, participants reported a marked negative impact of hyperhidrosis on various measures, including emotional status, ability to participate in daily and social activities, productivity at work and number of clothing changes per day. During the post-treatment period, statistically and clinically significantly greater improvements in all of these parameters were observed for the BTX-A group compared with the placebo group ( P  〈 0·01). The BTX-A group improvements were observed within 1 week of treatment, and were sustained with little or no decline throughout the 16-week follow-up period. Compared with the baseline HHIQ responses regarding treatment history, BTX-A treatment resulted in a greater level of overall treatment satisfaction than did many other hyperhidrosis treatments. In addition, patients treated with BTX-A exhibited statistically significantly greater improvement in the physical component summary score of the SF-12 at 16 weeks than did placebo-treated patients ( P  ≤ 0·019). Conclusions  Hyperhidrosis is associated with a substantial QOL burden; however, QOL is markedly improved with BTX-A treatment.

    Description / Table of Contents: Abstract A 29-year-old female patient with an autoimmune subepidermal blistering disease had linear deposits of both IgA and IgG at the basement membrane zone. Clinically, the patient presented with tense blisters on the face, trunk, extremities and oral mucosa. Histologically, we found a subepidermal blister formation and a predominantly neutrophilic infiltrate. Direct immunofluorescence showed linear deposits of IgA along the basement membrane zone, as well as linear deposits of IgG and C3 as typically found in bullous pemphigoid. Indirect immunofluorescence demonstrated circulating IgA and IgG autoantibodies. This case extends previous reports on a subgroup of patients with subepidermal blistering diseases characterized by the presence of both IgA and IgG anti-basement membrane antibodies. These patients reveal clinical, histological and immunopathological features of linear IgA disease and bullous pemphigoid.
    Notes: Zusammenfassung Wir berichten über eine 29jährige Patientin mit einer subepidermal blasenbildenden Autoimmundermatose, die durch lineare Ablagerungen von IgA- und IgG-Antikörpern an der dermoepidermalen Junktionszone gekennzeichnet ist. Klinisch fanden sich pralle Bläschen im Gesicht, am Stamm, an den Extremitäten und an der Mundschleimhaut. Histologisch sahen wir eine subepidermale Blasenbildung und ein neutrophilenreiches Entzündungsinfiltrat. Mittels direkter Immunfluoreszenz fanden sich in der Haut der Patientin lineare IgA-Ablagerungen an der Basalmembranzone. Ungewöhnlich war jedoch der gleichzeitige Nachweis von linearen IgG- und C3-Ablagerungen, die typischerweise beim bullösen Pemphigoid vorkommen. Auch im Serum der Patientin fanden sich Autoantikörper sowohl der IgA- als auch der IgG-Klasse. Der Fall dieser Patientin bestätigt frühere Berichte, daß es bei den subepidermal blasenbildenden Autoimmundermatosen eine Untergruppe von Patienten mit gleichzeitigem Nachweis von IgA- und IgG-Antikörpern gibt, bei denen sich klinische, histologische und immunpathologische Merkmale von linearer IgA-Dermatose und bullösem Pemphigoid überlappen.
