A set of glycoproteins recognized by A2B5 antibody with major bands at 55 and 76 kDa is overexpressed in human head and neck squamous cell carcinomas.

A2B5 antibody was found to strongly label frozen sections of human head and neck squamous cell carcinomas. The low amount of glycolipids (c-series gangliosides and sulfatides) purified from the same tumors and reactive with A2B5 by immunostaining on thin-layer plates could not account for the high level of tissue labeling. Proteins were extracted from both normal tissues and squamous cell carcinomas and analyzed by Western blot with A2B5 antibody on PVDF membranes. The antibody was found to stain a set of glycoproteins with two major bands at 55 and 76 kDa present in normal tissues and overexpressed in carcinomas. Staining was abolished by prior treatment of the PVDF membranes either with Arthrobacter ureafaciens neuraminidase or with a solution of 10 mM periodate that is known to destroy carbohydrates. Our results show that the carbohydrate epitope recognized by A2B5 antibody can be displayed by both glycolipids and glycoproteins.

[Mental and behavior disorders in children placed in long term care institutions in Hunedoara, Cluj and Timis, Romania].

This article originated from a descriptive study done in 1992-1993 in Romania. The study was initiated and coordinated by the French NGO "Médecins du Monde", was directed by three health organizations (the "Observatoire régional de la santé de Languedoc-Roussillon", the "Unité 265 INSERM", the Romanian League for Mental Health) and was granted by the Romanian government and the European Community Commission. There are many publications about children's mental and behavioural disorders. But there are few epidemiological studies concerning the prevalence of these disorders among children suffering from social difficulties. This article explores the prevalence of mental and behavioral disorders among Romanian children institutionalized and examines specifically the prevalence among children in homes for children ("Casa de Copii") to compare it with similar data published in other countries. First, this article explores the prevalence of mental and behavioral disorders among a population of 4.692 children institutionalized in three Romanian districts in 1992. Second, this article examines the prevalence of these disorders among a population of 1.610 children institutionalized in homes for children ("Casa de Copii"), i.e. 1,610 children ages ranging from 4 to 18 years and suffering from social difficulties. Homes for children are out of home care institutions which are specialised neither in physical deficiencies nor in mental disorders. From this population, a randomized sample of 508 children has been screened by physicians and psychologists based on an evaluation protocol. Then each disorder has been coded as a diagnosis, according to the Tenth International Disease Classification (WHO). Fifty-four percent (54%) of the children institutionalized in homes for children in three Romanian districts in 1992 had a main diagnosis of mental or behavioural disorder. Third, this article compares our results to the prevalence found in other studies. Only three studies could be selected for comparison because they were the only ones with the three following criteria: 1) a focus on a population of children or a randomized sample of children ages ranging from 4 to 18 years, 2) a focus on children suffering from social difficulties and living in out of home care, 3) disorders evaluated by health professionals or a validated methodology. Our results lies within the range of prevalence found in the literature (41-70%). A discussion follows regarding methodological matters and critiques that may be launched from such a comparative designs. Finally, the high frequency of institutionalization in Romania in 1992 illustrates how few solutions there were to social difficulties and how exaggerated institutionalization was. This was a very different situation compared to Western Europe and Northern America. This should not hide, however, the actual modifications that took place in Romania. This article concludes with a brief description of the modifications which have been generated by the evaluation protocol used here.

[The newborn infant of a diabetic mother].

The authors present a case of a newborn of a diabetic mother with fatal outcome in the 6th day postnatally. The principal troubles in newborn were: fetal macrosomy, hypoglycemia and a lot of congenital malformations. They discuss the relationship between the maternal alteration of hydrocarbonate metabolism and the troubles in fetus and newborn.

[A case of the prune belly syndrome].

Rare heterogeneous syndrome, the prune belly syndrome was first described in 1839 and associates the agenesis of the abdominal musculature with other complex malformations of the genitourinary tract and bilateral cryptorchidism. In this plurimalformative context, the main evolutive problem is represented by the chronic renal insufficiency. The work presents a new case of prune belly syndrome which through its clinical evolutive aspects joins the category of classical cases published in literature.

[A case of acute hyaline membrane pneumopathy in a 3-month-old infant].

The authors discuss the anatomoclinical case of an infant 3 months and 2 weeks old, presenting a clinical picture of interstitial pneumonia, in shock. Microscopic histologic examination of the lung revealed a lung disease with hyaline membranes, an unusual entity after the neonatal period. The authors assume the formation of hyaline membranes to be due to prolonged shock and the inadequate alveolar surfactant.
