Clinical experience with infants with Robin sequence: a prospective study.

OBJECTIVE: To study the clinical course of patients with Robin sequence (RS) during the first 6 months of life. DESIGN: A longitudinal prospective study of children with RS. SETTING: Hospital de Reabilitação de Anomalias Craniofaciais, Universidade de São Paulo, Bauru-SP, Brazil, 1997 and 1998. PATIENTS: Sixty-two children were studied from hospital admission to 6 months of age. Thirty-three (53.2%) presented with probable isolated RS (PIRS), 25 (40.3%) presented with syndromes or other malformations associated with RS, and 4 (6.5%) presented with RS with neurological involvement. INTERVENTIONS: The type of respiratory tract obstruction was defined by nasopharyngoscopy. The patients with type 1 and type 2 obstruction underwent nasopharyngeal intubation (NPI), and glossopexy was indicated in patients with type 1 obstruction who did not show clinical improvement with this procedure. Tracheostomy was indicated in patients with type 2 obstruction who did not show a good course after NPI, in patients with type 1 obstruction who did not show good course after glossopexy, and in patients with type 3 and type 4 obstruction. RESULTS: Prone position treatment (PPT) or NPI was the definitive treatment in 25 cases (75.8%) of PIRS and in 13 cases (52%) of syndromes or other malformations. Among the children with type 1 obstruction, 24 (51.1%) were submitted exclusively to PPT and 12 (25.5%) to NPI. With the type 2 groups, only one (12.5%) received PPT, and three (37.5%) were treated exclusively with NPI. All 15 infants treated exclusively with NPI (24.4%) presented with good weight, length, and neuromotor development. CONCLUSIONS: Most patients with PIRS and type 1 obstruction improved without surgical intervention. NPI should be the initial treatment in all patients with RS with type 1 and type 2 obstruction who present with important respiratory and feeding difficulties.

[Evaluation of a supplementary nutrition program].

The objective of this study was to evaluate the impact of a feeding supplementation program on the growth of undernourished children younger than 5 years in the city of Guariba, state of São Paulo, Brazil. The sample consisted of 469 malnourished children enrolled in a feeding supplementation program sponsored by the State Health Secretariat. The children were divided into four groups according to how long they had been enrolled in the program: in group 1, the children had been enrolled for up to 12 months; in group 2, from 12 to 24 months; in group 3 from 24 to 36 months; and in group 4 the children had been enrolled for more than 35 months. Percentiles for weight/age, height/age and weight/height were calculated for each child. To assess the impact of the program, reference curves for the anthropometric profile were constructed based on expected variations in population percentiles. The changes observed in each group were analyzed statistically (McNemar). Groups 1 and 2 presented weight recovery and gains in the weight/height ratios for the most severely malnourished children; in group 3, the weight/height ratio was maintained and there was a discrete tendency towards weight recovery, which was reversed in group 4, in which the weight was again low in relation to height. The feeding supplementation program temporarily minimized severe nutritional deficiencies but was not sufficient to recover and maintain normal growth.
