Ulnar ray a/hypoplasia: evidence for a developmental field defect on the basis of genetic heterogeneity. Report of three Brazilian families.

We report on five Brazilian patients from three unrelated families with congenital anomalies of the upper limbs. Ulnar aplasia/hypoplasia was the main reason for examining these patients. Evidence for existence of an ulnar developmental field is based on genetic heterogeneity. Clinical and genetic aspects of the ulnar ray defects are discussed.

Prova de absorção de gordura em crianças.

To overcome the difficulties observed with fecal fat estimations, we studied fat absorption in 4 m to 12 years old children, assessing increments of serum triglycerides after administration of corn oil. Eighteen well-nourished children without gastrointestinal symptoms or parasites, 31 children with protein-calorie malnutrition (PCM), with or without protracted diarrhea and/or intestinal parasites and nine children with specific malabsorptive entities were studied. Serum triglycerides (TG) were measured before, 2 and 4 hours after the administration of 2 g/kg of corn oil per os. For control infants below 2 years no significant differences between the fasting level and those after 2 and 4 hours were observed. For children above this age significant absorption occurred by 2 hours but more intensively after 4 hours, an increment of TG above 35 mg% being considered normal. A good discrimination between TG increments of controls and malabsorptive children over 2 years was observed. In conclusion, the oral fat loading test, is applicable for children over 2 year of age. For infants below this age other schedules should be tested.

The determination of iron, lead, copper and zinc in the hair of children between 22 and 85 months old

In this study the levels of Cu, Fe, Pb and Zn, determined in hair of healthy children (25-85 months), living at Araraquara (São Paulo, Brasil) are reported. Analytical determinations were carried out by using atomic absorption spectrometry employing an air acetylene flame. The results obtained are discussed with regard to effect of sex and age, as well compared with others analogous studies.

Nutritional management and weight changes during hospitalization of Brazilian infants with diarrhoea: Primary reliance on oral feeding or continuous nasogastric drip with locally made, modulated minced chicken formula

The nutritional management of infants admitted with diarrhoea to the University Hospital of Botucatu includes a change from bolus feeding of a modulated minced-chicken formula to a continuous nasogastric drip (NGD) feeding, whenever the required calorie intake is not achieved or the diarrhoea does not subside. To evaluate this approach, the clinical course and weight changes of 63 children, aged 1-20 months, were reviewed; most (81 per cent) were below the third percentile for weight at admission and 76 per cent had a total duration of diarrhoea ≥10 days. Associated infections, mainly systemic, were present at or after admission in 70 per cent of them. Twenty-five survivors needed nutritional support (NS), predominantly NGD, for a median duration of 30 per cent of their admission time, and were compared to 31 survivors managed without NS. Those who necessitated NS lost weight for a significantly longer median time (12x4 days, p<0.005), but their total weight loss was similar (5x4 per cent) as well as diarrhoea's duration (8x7 days). There was a tendency for a longer hospitalization (21x16 days 0.05

A case of terminal long arm deletion of chromosome 6

A four-year-old girl with deletion of chromosomal band 6q24 → qter is described. Clinical features include growth and psychomotor retardation, microcephaly, convergent strabismus, bulbous nose, long philtrum, short neck and cardiopathy.

O programa de saúde bucal para crianças pré-escolares em Araraquara-SP-O desempenho em 1988.

This paper reports the composition change of the dmf-teeth index, outcome from dental health program for the 3 to 6 year old pre-school children population, enrolled in kindergartens in Araraquara-SP, in 1988. The program performance promotes a major contribution of the f component to the dmf-teeth index.

Utilidade dos métodos imuno-histoquímicos para o diagnóstico anátomo-patológico.

In order to determine the value of immunohistochemical staining methods for the morphologic diagnosis, we studied 949 histologic specimens sent for consultation to the Immunohistochemistry Laboratory of Department of Pathology of the Medical School of Botucatu in the period 1984-1989. All case were submitted to the immunoperoxidase staining with the methods PAP or ABC. Immunohistochemical stains confirmed the original morphologic diagnosis in 468 cases (49.3%); made the definitive diagnosis from a list of differential diagnostic possibilities in 244 cases (25.7%); provided contributory information in 74 cases (7.8%); were non-contributory in 114 cases (12%) and rendered an unsuspected diagnosis in 49 cases (5.2%). In some cases with non-contributory information the differences in methods of fixation might have led to suboptimal preservation of tissue antigens. The immunohistochemical staining may provide important and sometimes essential informations for definitive diagnosis. This technique was particularly useful for differential diagnosis between carcinoma, lymphoma and melanoma.

Contribuição do estudo imuno-histoquímico para o diagnóstico anátomo-patológico.

In order to determine the value of immunohistochemical staining methods for morphologic diagnosis specimens of 949 cases received at the Immunohistochemistry Laboratory of the Department of Pathology of the Medical School of Botucatu, in the period 1984-1989 were reviewed. All of them were submitted to the immunoperoxidase staining (PAP or ABC). The main morphologic diagnosis was confirmed in 468 cases (49.3%); the definitive diagnosis was made in 244 cases (25.7%) that had only differential diagnosis, and contributory information was provided in 74 cases (7.8%); the immunohistochemical staining was non-contributory in 114 cases (12%). It rendered an unsuspected diagnosis in 49 cases (5.2%). The analysis of these cases shows that immunohistochemical methods may provide important and sometimes essential informations for definitive diagnosis. This technique is particularly useful for distinguishing between carcinoma, lymphoma and melanoma.
