[Childhood Henoch-Schönlein syndrome--common and uncommon features, complications, Finkelstein-Seidlmayer variant and management]

Although Henoch-Schönlein syndrome can occur at any age, it is overwhelmingly a disease of childhood. Indeed, Henoch-Schönlein syndrome is the most common vasculitis that affects children. The clinical features of this vasculitis are well documented, and the diagnosis is generally not difficult. This article briefly reviews both common and uncommon clinical aspects of the condition and information concerning therapy. A further focus of this review is recent information concerning abnormalities of immunoglobulin IgA1 glycosylation and the role of aberrantly glycosylated immunoglobulins in the development of Henoch-Schönlein syndrome. The final focus of the article is acute hemorrhagic edema, a benign vasculitis limited to the skin, which is characterized by circinate, medallion-like purpura, and ecchymoses and occurs in children younger than 4 years of age. The nosologic position of acute hemorrhagic edema, which has also been called Finkelstein-Seidlmayer syndrome, as a variant of Henoch-Schönlein syndrome is the subject of considerable debate, but most authors agree that there are sufficient clinical and prognostic differences to consider it a separate entity.

[The role of thoracoscopy in paediatric spontaneous pneumothorax]

Spontaneous pneumothorax in children is an emergency. A rapid and structured treatment is necessary. Indicating clinical signs are dyspnoea with unilateral reduced breath sounds and hypersonic percussion note. Chest x-ray confirms diagnosis. CT scan shows detailed information's of pathological changes in lung tissue and offers important considerations for the therapy. Today video assisted thoracoscopic surgery (VATS) takes a central role in the treatment of spontaneous pneumothorax. Thoracoscopy completes diagnosis detecting the pathologies, which were missed in imaging procedures. Definitive surgical treatment is performed simultaneously in the same anaesthesia.

[The mandatory diaper peek in newborn girls]

We present a 3 day old girl born at term presenting with an interlabial, cystic mass. Pregnancy, delivery and routine antenatal screening were unremarkable. The smooth lesion was located in the anterior half of the vulva, covered with thin vessels. The medially displaced urethra and the medio-posteriorly displaced hymen were identified. Voiding was not impaired. We discuss the differential diagnosis of vulvar masses in the newborn girl. A thorough clinical examination must be the standard of care of pediatric examinations in infants.

[The child with a bleeding tendency]

In this review some basic aspects of the clinical presentation, the laboratory testing and the management of a child with a bleeding tendency are discussed. It should help the physician in making the decision whether a laboratory examination in a child with a history of bleedings is necessary or not. In addition, the most frequent mechanisms for a defective hemostasis are explained.

[Pediatric cardiac disease: indications for family screening and risk stratification]

In some forms of cardiac disease in childhood, familial occurrence is frequent. This implies the question whether family members should undergo cardiologic screening examinations. For cardiomyopathies the familiarity is so frequent and morbidity so important that examination by echo of all first degree relatives is recommended. As these cardiomyopathies may develop its phenotype all along a lifetime, repetitive examinations usually are indicated. For the primary electrical diseases the so called channelopathies the same is true, as for the high rate of familial occurrence and the high morbidity. Thus ECG screening of first degree relatives is recommended. In a child with congenital heart disease there are no recommendations with regard to familial screening and cardiological examinations usually are indicated only in case of clinical suspicion for heart disease.

Systemsklerose

Die Systemsklerose ist charakterisiert durch autoimmune Phänomene und eine progressive Fibrose. Klinische Charakteristika sind neben der Sklerodermie ein ausgeprägtes Raynaud-Phänomen und Abnormitäten der Nagelfalzkapillaren, ferner pulmonale, renale, kardiale und intestinale Veränderungen. In der Regel wird eine diffuse von einer limitierten Form unterschieden. Die diffuse Form führt zu einer Sklerose des gesamten Integumentes, ist assoziiert mit dem Auto-antikörper Scl-70 und zeichnet sich durch eine rasche Krankheitsprogression aus. Die limitierte Form betrifft die distalen Extremitäten und das Gesicht, ist assoziiert mit dem centromer Autoantikörper und führt schleichend, über mehrere Jahre zu viszeralen Problemen. Neue therapeutische Möglichkeiten können zu einer besseren Lebensqualität verhelfen und verpflichten zu einem systematischen Krankheitsmonitoring.

Clinical and immunologic effects of H1 antihistamine preventive medication during honeybee venom immunotherapy

BACKGROUND: H1 antihistamines increase safety during allergen-specific immunotherapy and might influence the outcome because of immunoregulatory effects. OBJECTIVE: We sought to analyze the influence of 5 mg of levocetirizine (LC) on the safety, efficacy, and immunologic effects of ultrarush honeybee venom immunotherapy (BVIT). METHOD: In a double-blind, placebo-controlled study 54 patients with honeybee venom allergy received LC or placebo from 2 days before BVIT to day 21. Side effects during dose increase and systemic allergic reactions (SARs) to a sting challenge after 120 days were analyzed. Allergen-specific immune response was investigated in skin, serum, and allergen-stimulated T-cell cultures. RESULTS: Side effects were significantly more frequent in patients receiving placebo. Four patients receiving placebo dropped out because of side effects. SARs to the sting challenge occurred in 8 patients (6 in the LC group and 2 in the placebo group). Seven SARs were only cutaneous, and 1 in the placebo group was also respiratory. Difference of SARs caused by the sting challenge was insignificant. Specific IgG levels increased significantly in both groups. Major allergen phospholipase A(2)-stimulated T cells from both groups showed a slightly decreased proliferation. The decrease in IFN-gamma and IL-13 levels with placebo was not prominent with LC, whereas IL-10 levels showed a significant increase in the LC group only. Decreased histamine receptor (HR)1/HR2 ratio in allergen-specific T cells on day 21 in the placebo group was prevented by LC. CONCLUSIONS: LC reduces side effects during dose increase without influencing the efficacy of BVIT. LC modulates the natural course of allergen-specific immune response and affects the expression of HRs and cytokine production by allergen-specific T cells.
