Methods: The cases of one hundred fourteen patients with resected distant metastases were reviewed and subjected to multivariate analysis.

Five patients in the same family showed small keratotic plugs of the palmar creases. Transmission in lineage was consistent with an autosomal dominant pattern of inheritance. The syndrome was highly associated with ichthyosis vulgaris in several members of the family.

Benign neonatal familial convulsions comprise a distinct epileptic syndrome with an autosomal mode of transmission. The electroclinical signs of seizures in this syndrome are not yet well defined. In 3 children from two families presenting with benign neonatal familial convulsions, 14 seizures were recorded during electroencephalographic (EEG)-video sessions.

Arteriovenous malformations (AVM) are vascular anomalies containing a communication between an artery and a vein without an intervening capillary bed. In 1990, Klippel and Trenaunay reported a patient with limb overgrowth, cutaneous angiomata and varicose veins. In 1918, Parkes Weber mentioned the additional feature of AVM terming the condition 'hemangiectatic hypertrophy'.

Blue nevi may rarely appear in multiple form and grouped in a circumscribed area, a pattern of arrangement that is more properly designed under the term agminated blue nevi. In this paper a new case with light and ultrastructural studies is described, and the previously reported cases are reviewed. Histologically, there was a characteristic perifollicular arrangement of dermal melanocytes, most of which showed ultrastructurally an extracellular sheath.

Article Synopsis
  • Dermal melanocytosis involves the presence of melanocytes in the skin and has various forms, like blue nevus and Mongolian spot.
  • A 28-year-old woman had a unique case with gray-blue pigmentation on her trunk, which had been there since birth, showing unusual dermal melanocytes upon examination.
  • The case is distinct from other recognized forms, leading the authors to suggest the term "congenital segmental dermal melanocytosis" for this unusual condition.

The incidence of bacteria as etiological agents of diseases in larvae of bivalve mollusks, is well documented in the literature. In this study, a series of test were performed to identify and estimate pathogenic level of marine bacteria isolated during an epizootic in a larval culture system of the tropical scallop Euvola ziczac. Such bacteria was identified as Pseudomonas sp.

Thirteen to 43% of patients with infantile spasms (IS) have other types of seizures, which are considered a feature of an unfavourable prognosis and, to some extent, as a contra-indication for steroid treatment. The present series comprised 43 patients treated with steroids, who suffered from other types of seizures prior to IS. The first seizures resulted from 2 different conditions, correlated to a different outcome of epilepsy.

There are conflicting reports in the literature about the possible association between left-handedness and immune disorders, including autoimmune diseases as well as allergies. In this study we compared the distribution of right- and left-handers, assessed with the Edinburgh Handedness Inventory, in a group of patients consulting an allergy clinic and a control population with a similar sex and age distribution. There was no overall association between left-handedness and allergies, although we found a tendency towards left-handedness in patients whose allergic symptoms started before puberty, suggesting that left-handers may have an increased predisposition to allergic disease that manifests itself during early life.

Authors review 53 children, aged 0 to 14 years, affected with cerebrovascular ischemic strokes. Largest aetiological groups were: a) congenital heart disease, 16 patients; b) arteritis of unknown cause, 11; c) idiopathic arterial occlusion without arteritis images on angiography, 7; d) moyamoya disease, 6; and d) local or systemic infections, 5. The mode of onset was as completed stroke in 72% and stroke in evolution in 24%.
