ABSTRACT. Objective. Between October and November 2003, several infants with encephalopathy were hospitalized in pediatric intensive care units in Israel. Two died of cardiomyopathy. Analysis of the accumulated data showed that all had been fed the same brand of soy-based formula (Remedia Super Soya 1), specifically manufactured for the Israeli market. The source was identified on November 6, 2003, when a 5.5-month-old infant was admitted to Sourasky Medical Center with upbeat nystagmus, ophthalmoplegia, and vomiting. Wernicke's encephalopathy was suspected, and treatment with supplementary thiamine was started. His condition improved within hours. Detailed history revealed that the infant was being fed the same formula, raising suspicions that it was deficient in thiamine. The formula was tested by the Israeli public health authorities, and the thiamine level was found to be undetectable (<0.5 g/g). The product was pulled from the shelves, and the public was alerted. Thiamine deficiency in infants is very rare in developed countries. The aim of this study was to report the epidemiology of the outbreak and to describe the diagnosis, clinical course, and outcome of 9 affected infants in our care.Methods. After the index case, an additional 8 infants were identified in our centers by medical history, physical examination, and laboratory testing. The group consisted of 6 male and 3 female infants aged 2 to 12 months. All were assessed with the erythrocyte transketolase activity assay, wherein the extent of thiamine deficiency is expressed in percentage stimulation compared with baseline (thiamine pyrophosphate effect [TPPE]). Normal values range from 0% to 15%; a value of 15% to 25% indicates thiamine deficiency, and >25% indicates severe deficiency. Blood lactate levels (normal: 0.5-2 mmol/L) were measured in 6 infants, cerebrospinal fluid lactate in 2 (normal: 0.5-2 mmol/L), and blood pyruvate in 4 (normal: 0.03-0.08 mmol/L). The diagnostic criteria for thiamine deficiency were abnormal transketolase activity and/or unexplained lactic acidosis. Treatment consisted of intramuscular thiamine 50 mg/day for 14 days combined with a switch to another infant formula.Results. Early symptoms were nonspecific and included mainly vomiting (n ‫؍‬ 8), lethargy (n ‫؍‬ 7), irritability (n ‫؍‬ 5), abdominal distension (n ‫؍‬ 4), diarrhea (n ‫؍‬ 4), respiratory symptoms (n ‫؍‬ 4), developmental delay (n ‫؍‬ 3), and failure to thrive (n ‫؍‬ 2). Infection was found in all cases. Six infants were admitted with fever. One patient had clinical dysentery and group C Salmonella sepsis; the others had mild infection: acute gastroenteritis (n ‫؍‬ 2); upper respiratory infection (n ‫؍‬ 2); and bronchopneumonia, acute bronchitis, and viral infection (n ‫؍‬ 1 each). Two infants were treated with antibiotics. Three infants had neurologic symptoms of ophthalmoplegia with bilateral abduction deficit with or without upbeat nystagmus. All 3 had blood lactic acidosis, and 2 had high cerebrospinal fluid lactate levels. Patient 1, our index case, wa...

Objective To evaluate the impact of a quality improvement intervention during the first hour of life ("Golden Hour") on short-term preterm neonatal outcome. Study design A comprehensive protocol designed for initial stabilization and treatment of preterm infants that included cord blood sampling, use of a dedicated resuscitation room and improved team communication using Crew Resource Management tools. The infants admitted before and after implementation of the protocol were retrospectively compared in a matched case-control design. Results There were 194 infants in the intervention group and 194 controls. Admission temperatures improved significantly from a mean of 35.26°C to 36.26°C (P < 0.001), and late-onset sepsis and bronchopulmonary dysplasia rates lowered significantly (P = 0.035 and P = 0.028, respectively) in the intervention group. There was trend towards reduction in early blood transfusion and ventilation duration. Conclusions A "Golden Hour" quality improvement intervention was of significant benefit for preterm neonates. Further follow-up to assess long-term effects is warranted.

SMS updating is an easy and user-friendly technology that enriches the modalities of information delivery to parents of hospitalized preterm infants. It is a complementary and useful tool for encouraging and improving personal communication between parents and medical staff and should be considered part of quality improvement in health care.
