[Language disorders in the light of K-ABC].

OBJECTIVE: Problems of terminology have hampered the study of dysfunctional school age children, and a confusing array of labels has been applied to them. This is the case for speech and language disorders. The challenge to the pediatrician is to arrive at an integrated diagnosis that will lead to useful strategies for intervention. PATIENTS AND METHODS: The K-ABC test, as a new instrument in the light of a new conception of intelligence, has been used as a tool for assessing language disorders in a sample of 261 preschool children aged 3 to 6 years. The results were analyzed by the Chi-square test and the stratified Chi-square test of Mantel-Haenzel as a discriminator between two variables. RESULTS: Bilingualism, father's and mother's educational level and jobs, as sociocultural and/or socioeconomic factors, emerged as statistically significant. CONCLUSIONS: The main conclusions refer to the ability to discriminate between learning and language disabilities and the relationship between language disorders and the bilingual condition or sociocultural markers, such as profession and academic achievement, of the parents. This article highlights the value of pediatrician-psychologist collaborations.

Hypertrichosis, atrophic skin, ectropion, and macrostomia (Barber-Say syndrome): report of a new case.

We report on a child, born to a consanguineous parents, who presented with a multiple congenital anomalies (MCA) pattern consisting of severe hypertrichosis, macrostomia, ectropion, and atrophic skin. To our knowledge this is the third case with this combination of defects. The two previous cases were reported by Barber et al. [Syndrome Identification VIII(1):6-9, 1982], and David et al. [Am J Med Genet 41:192-195, 1991].

[Arrhythmia-hyperkalemia in a newborn infant with congenital adrenogenital syndrome. Usefulness of cardioversion].

Cardiac arrhythmias can be life-threatening situations requiring swift action. Disorders of heart beat in pediatric age and, mainly, in neonatal period are very rare out of those occurring after cardiac surgery. Because of this there can be no training in their management on the part of pediatricians. A case of hyperkalemic arrhythmia in a newborn with adrenogenital syndrome in which electrical cardioversion was successful is presented. Furthermore, sequential electrocardiographic changes with hyperkalemia are shown and comments on physiopathology, diagnosis, treatment and etiology are made.

[Asymmetrical otocraniofacial syndrome (hemifacial microsomy) in discordant monozygotic twins. Otologic aspects].

The authors present a case of otocraniofacial syndrome with asymmetric involvement (hemifacial microsomia) in monozygotic twins discordant for the syndrome. Only a few cases of discordance in monozygotic twins have been previously describe in world literature. The occurrence of discordance in identical twins indicates the significance of exogenous factors. The patient had bilateral involvement right side being more severely involved than left side. Conductive hearing loss due to middle ear abnormalities was also present. Usefulness of tomographic examination to study structural ear abnormalities is emphasized, and some comments on the otologic involvement in this syndrome are made.

[Acute pancreatitis (a Coxsackie B2?) and associated anomalies].

Authors report one case of acute pancreatitis in an obese twelve-year-old girl. The clinical picture appeared, without antecedent causes, as acute abdomen which required operation. Reduced echodensity of the pancreas was not found. The patient improved and recovered completely, her course being uneventful two years later. Scoliosis due to hemivertebra, and renal hypoplasia were present. No pancreatic malformation according to hypothesis of commun pathogenic mechanism was identified. Antibody titer to coxsackie B2 suggesting etiologic role was obtained. Amylase creatinine clearance ratio was calculated and suitability of establishing diagnostic values for pediatric ages is emphasized.

[Neonatal nonbacterial thrombotic endocarditis].

A case of neonatal nonbacterial thrombotic endocarditis confirmed at autopsy was identified in the neonatal intensive care unit. The infant suffered from hyaline membrane and disseminated intravascular coagulation. A degenerative verrucal endocarditis at the tricuspid and aortic valves was demonstrated in addition to pulmonary and renal embolism. Vegetations on the heart valves of the newborn infants are rare at necropsy and yet to be diagnosed antemortem. Prospective studies are needed to determine whether high-risk patients should be screened periodically by echocardiographic technique.

[Acute suppurative thyroiditis].

Authors present a case of acute suppurative thyroiditis gland being normal before in a 5 8/12 year old. Plasma TSH, T3 and T4 remained within normal ranges. An alpha haemolytic streptococcus was isolated from suppuration and thyroglossal duct remnant was not identified. Surgical treatment was quickly followed by recovery. Some considerations about clinical picture, pathogenesis, etiology, prognosis and treatment are made. Usefulness of thyroid scan is emphasized.

[Cutis marmorata telangiectatica congenita (author's transl)].

Authors report a new case of cutis marmorata telangiectatica congenita. This disease has been preferably described by dermatologists and few issues in the pediatrics literature have been published. This is a rare illness recognizable at birth which must be knowed by pediatricians to establish the diagnosis and prognosis in the beginning. A new case with typical features is presented being of localized distribution and having as associated abnormalities. Hemiatrophy, enlarged inferior extremity without Klippel-Trenaunay syndrome and physical growth retardation.
