A new bolaamphiphile analog featuring carbamate moieties was synthesized in six steps starting from thymidine. The amphiphile structure exhibits nucleoside-sugar polar heads attached to a hydrophobic spacer via carbamate (urethane) functions. This molecular structure, which possesses additional H-bonding capabilities, induces the stabilization of low-molecular-weight gels (LMWGs) in water.

The child, born to consanguinous parents, presented at birth with a verrucous hyperkeratosis involving face, trunk, and limbs, but sparing palms and soles. No visceral or skeletal abnormality was associated and neurosensory status was normal.

Aims: To investigate this hypothesis in children, and to review our experience in the management of these patients.
Methods: A retrospective analysis of 77 paediatric cases of EM or SJS admitted to the Children's Hospital in Bordeaux between 1974 and 1998.
Background: During twin pregnancies, several complications may result in the death of a co-twin depending on the date of death. We describe herein 2 infant survivors of monozygotic twin pairs with 2 distinct possible complications: a aplasia cutis congenita and Volkmann ischemic contracture.
Observations: One infant had extensive aplasia cutis congenita with an associated monozygotic co-twin who died at 3 months of gestation, and the other child had a localized arm defect due to Volkmann ischemic contracture and brain damage, with a co-twin who died at approximately 6 weeks of gestation.

Introduction: Hemangiomas are the most frequent skin tumor of childhood. Usually, a "wait and see" policy is adopted. However, a sacral hemangioma may reveal occult neurodysraphism.

It still remains the most frequent acute panniculitis, for which the diagnosis is almost always clinical. In a retrospective study of 27 pediatric patients, we have attempted to clarify the clinical spectrum and prognosis of this disease and discuss the differential diagnosis of nodular eruptions on the lower limbs of children.

Observations: Direct examination of pustule smears showed M furfur yeasts in eight of 13 cases involving neonates with erythema and papulopustules of the face, neck, and scalp (mean age at onset, 22 days [range, 7 to 30 days]).
Background: The outcome of granuloma annulare in childhood is not well defined.
Population And Methods: A questionnaire was sent to the family of 40 children under 15 years of age examined for granuloma annulare from 1987 to 1992. Thirty of them answered, permitting a retrospective study.
Background: Lymphomatoid papulosis (LyP), uncommon in children, has a benign clinical course in contrast with a malignant histology.
Case Report: A 9-year old boy developed nodular skin lesions for 6 months on the scalp and penis and a papule skin on his trunk. Surgical excision of scalp nodules was performed to prevent necrosis and ulceration of the ear.
Background: Indications for active treatment of hemangiomas are those lesions which, by virtue of their size and site, compromise vital structures. The treatment of choice is oral or intravenous corticosteroids, but interferon alpha may represent alternative therapy.
Case Report: A 15-day-old girl was admitted for congenital hypothyroidism.
Over 20 months, we have treated 74 patients (59 children less than 12 years of age) with port-wine stains (PWS) using a 585-nm flashlamp-pulsed dye laser (SPTL-1, Candela Corp., Wayland, Mass., USA) after topical anesthesia with Emla cream.

Dermatophytosis due to Microsporum langeronii was observed in a 21-day neonate born in Bordeaux, France to a mother of West African origin. A typical misleading manifestations were: non alopecic squamation of the scalp with seborrhoea associated with circineous vesiculo-squamous lesions of the forehead. The source of the contamination was undoubtedly the mother who presented squamation without alopecia of the scalp.

We report an unusual case of cutaneous mastocytosis without systemic involvement in a 9-month old infant. Clinical expression was entirely functional (pruritus, urticaria) with no permanent lesions.

Erythromelalgia is an acrosyndrome characterized by paroxysmal manifestations associating erythema, local sensations of warmth and pain which improve with exposure to cold. Childhood forms, exceptional and usually primary, are quite severe and particularly resistant to treatment. The search for a causal agent is most often negative and the pathogenesis remains to be determined.

A retrospective study of 40 infants that were hospitalised for urticaria has been made to clarify the factors that produce urticaria at that age. Certain clinical signs seem to be more frequent at this age, such as the bruised appearance of the lesions.
