Strawberry hemangioma in preterm infants.

Of 973 preterm infants, strawberry hemangioma was recorded in 124 during the first year of life, giving an overall frequency of 12.7%. Male:female ratio was 1:1.4. In 96 infants with birth weight below 1000 g, hemangioma occurred in 22 (22.9%), and in the group of very low-birth-weight infants (below 1500 g) the rate was 15.6%. Ninety-four infants had a single hemangioma and three had more than 10 lesions each. With one exception, no treatment was needed, as spontaneous involution started at age 5 to 12 months.

Bart's syndrome: a mechanobullous disease of the newborn. Report of five cases and review.

Bart's syndrome is one among the lesser known presentations of epidermolysis bullosa. It is characterized by congenital localized bullae of skin and mucous membranes sometimes associated with nail deformities, all of which disappear during the neonatal period. Early recognition allows for avoidance of inappropriate systemic or local therapy.

Neonatal pemphigus vulgaris.

The case history of a baby with neonatal pemphigus vulgaris is presented. This is the 13th case of pemphigus vulgaris during pregnancy reported in the literature. The correlations between the clinical, histologic, and immunofluorescent findings are discussed and a review of all previously reported cases is presented.

Elevated serum calcitriol concentrations do not fall in response to hyperphosphatemia in familial tumoral calcinosis.

Five affected members in two branches of a Druze Arab kindred presented with calcified deposits in or about the hips and knees, indicating the diagnosis of tumoral calcinosis. Serum vitamin D metabolite concentrations, immunoreactive parathyroid hormone, and the tubular reabsorption of phosphate were measured in three affected siblings, as well as in their parents and an unaffected sibling. Normocalcemia and hyperphosphatemia with an elevated tubular maximum for phosphate per glomerular filtration rate were found in the affected patients. Levels of serum immunoreactive parathyroid hormone were normal, and the calcitriol value (1,25-dihydroxyvitamin D) was normal or elevated in the three affected patients. A trial of a low-phosphorus diet and oral aluminum hydroxide gel did not lower serum phosphate levels or improve the calcified deposits. These findings suggest that serum calcitriol values do not decline in response to hyperphosphatemia in tumoral calcinosis and that hyperphosphatemia with elevated tubular reabsorption of phosphate is a constant feature of this disorder because the kidney fails to excrete the increased filtered load of phosphate.

Spastic paraparesis, mental retardation, and cutaneous pigmentation disorder. A new syndrome.

Four siblings in a family with a highly consanguineous background presented with an unusual combination of spastic paraparesis, muscle wasting, microcephaly, mental retardation, skeletal deformities, and cutaneous manifestations, ie, hypopigmented and hyperpigmented lesions and graying of the hair. An extensive workup including electromyography, muscle biopsy, and chromosomal analysis was unrewarding. An autosomal recessive inheritance is probable. A similar entity was recently reported from israel. The possibility that this previously unrecognized condition represents a new syndrome is suggested.

Hypernatremic dehydration and hypothermia in congenital lamellar ichthyosis.

Several events of hypernatremic dehydration occurred in five infants suffering from severe congenital lamellar ichthyosis. Simultaneously, four of them developed hypothermia. Both phenomena were probably caused by excessive water loss through the affected skin. In lamellar ichthyosis the skin loses its function as an effective barrier and therefore its role in water and temperature homeostasis is defective.

Scalp changes after fetal monitoring.

We prospectively studied 535 newborn infants who had been monitored during labour with scalp electrodes. Daily examination of scalp changes showed frequent transient mild lacerations, while severe complications were rare: seven (1.3%) had scalp ulceration and one (0.2%) developed scalp abscess.

Coral injury. Case report of injury, late effect and therapy.

A case of coral injury is presented. The injury may be complicated by immediate systemic reactions such as anaphylaxis and collapse, as well as local reactions that may last for months. Deeply seated coral fragments may induce a local inflammatory process of the foreign-body type. This causes pruritus refractory to antihistamines and topical steroid preparations. Satisfactory management consisted of local injection of steroids with a dermojet.

Congenital smooth muscle hamartoma of the skin.

Three cases of circumscribed congenital smooth muscle hamartoma (CSMH) in the neonate are described, including typical characteristics and differential diagnosis. This condition is a clearly defined, distinct entity, separate from similar lesions that are considered in the differential diagnosis. It is possibly more common than is evident from the literature.

Pseudorheumatoid nodules preceding granuloma annulare.

Pseudorheumatoid nodules are benign, self-limited phenomena, with a well-established association with granuloma annulare. Here, we present four girls in whom pseudorheumatoid nodules preceded the appearance of granuloma annulare. The natural course of these lesions is stressed and indications for surgical intervention are reviewed.

Segmental pigmentation disorder.

Pigmentary changes with a dermatomal distribution are described in 30 children. The disorder, up to now unrecognized as an entity, is apparently caused by an embryological determination. It is more obvious in children with darker skin, and seems to fade very slowly over the years. In our experience the incidence is 0.35%. No relation to other anomalies could be established.
