Unilateral laterothoracic exanthem in children: a new disease?

BACKGROUND: We have examined 18 children with a similar laterothoracic exanthem that appears to represent a distinct entity. OBJECTIVE: Our purpose was to describe the characteristic signs and clinical course of this eruption and its epidemiology data. METHODS: We observed the clinical course of the eruption in each child. RESULTS: The eruption has characteristic features. It occurs in a homogeneous age group (mean 23.3 months). It is initially unilateral and localized close to the axilla. The basic lesion is eczematous or scarlatiniform. The eruption evolves in two phases: it spreads centrifugally during the first 8 days and becomes more widespread on the tenth to fifteenth days, with predominant involvement on the half of the body initially affected. The lesions resolve spontaneously within 4 weeks. The long-term course is uneventful. CONCLUSION: The similarity of the cases suggests the existence of a new clinical entity. Many features favor a viral origin.

Atopic dermatitis: recent therapeutic advances.

New treatments were recently proposed for the management of severe atopic dermatitis (AD). They all act on some component of the immune reaction. Oral cyclosporine reduces the number of CD4+ cells, the secretion of interleukins, and the function of Langerhans cells. Although the action of oral cyclosporine at moderately high dosages is regular and rapid, the risk of serious side effects and the reappearance of progressive disease after stopping treatment limits the use of this drug in AD. Thymic hormone extracts in patients with severe AD affect the deficit of cellular immunity. gamma-Interferon inhibits IgE synthesis induced by interleukin-4, increases expression of Fc gamma receptors, and increases superoxide production by circulating monocytes. More recently, two other treatments were published: complexes of allergen and specific antibodies to Dermatophagoides pteronyssinus, and interleukin-2. All of these modalities have only a transitory effect, but they can help to modify a flare of severe AD.

Blepharophimosis, eczema, and growth and developmental delay in a young adult: late features of Dubowitz syndrome?

The Dubowitz syndrome is a rare autosomal recessive multiple congenital anomaly/mental retardation syndrome. We report here a case of a young adult presenting with several features consistent with this diagnosis. The differential diagnosis is discussed with respect to the absence of microcephaly and intrauterine growth retardation.

Management of severe atopic dermatitis.

The lack of knowledge concerning the pathophysiology of atopic dermatitis (AD) explains the absence of any specific treatment specially in severe atopic dermatitis. New treatments were recently suggested for the management of the disease. They all act on some component of the immune mechanisms which provoke the eczematous reactions. Among recent treatments proposed, I will discuss the use of cyclosporin A, puva therapy, thymopoietin and thymostimulin, antifungal therapy, alpha and gamma interferon, and treatment with interleukin 2.

[Kasabach-Merritt syndrome in children].

Kasabach-Merritt syndrome is a combination of thrombocytopenia, intravascular coagulation, and a rapid increase in the size of an angioma. Anemia and disseminated intravascular coagulation may develop. This infrequent syndrome is severe and may be life-threatening. Pathophysiologic mechanisms underlying the condition are incompletely understood and, consequently, many different treatments are used, including systemic corticosteroids, compression, embolization, antifibrinolytic agents, platelet aggregation inhibitors, irradiation, and others. From findings in eight personal cases, the authors review clinical and biological features, pathophysiologic hypotheses and therapeutic strategies.

[Cutaneous lesions in the orofaciodigital syndrome].

The term OFD syndrome designates a group of heterogeneous clinical patterns of which seven different types have been described. Type I, or Papillon Léage syndrome, is the most common pattern and the only type in which skin lesions occur. Type I OFD is a sex-linked dominant disorder. Two cases of OFD Type I with cystic lesions of the face are reported herein. The second patient also had polycystic kidneys. This combination has already been reported previously and all children with OFD should be investigated for polycystic kidney disease.
