PURPOSE: The purpose of this study is to compare the growth pattern of breast fed and formula fed infants in the first 1 year of life. METHODS: Anthropometric data (weight, length, head circumference) of at birth, 1, 3, 6, 9 and 12 months were collected by chart review and characteristics of subjects were collected by questionnaires. Among 358 infants, breast fed infants were 161 (84 males, 77 females) and formula fed infants were 90 (42 males, 48 females). Neither group was given solid foods before 4 months. The weight for age, length for age and head circumference for age were calculated. Breast fed infants were separated into 2 groups (breast fed for 4-11 months and breast fed for more than 12 months). RESULTS: Characteristics of infants and mothers were similar in both groups except for maternal age. Mean weight of breast fed group was lower than that of formula fed group at 12 months of age (male: P=0.004, female: P=0.004). However, mean weight of 12 months breast fed group was below formula fed groups weight at 9 and 12 months (P< 0.05). Mean length and head circumference were similar between groups. CONCLUSION: The growth indices of breast fed and formula fed infants are similar at birth, but weight curves of two groups differ in the first 1 year.

Isolated deficiency of 3-methylcrotonyl CoA carboxylase is a rare disorder of the catabolic pathway for leucine and many patients have mild symptoms or no symptom. However, the introduction of tandem mass spectrometry in newborn screening has revealed an unexpectedly high incidence of this disorder. We report an asymptomatic premature infant with isolated 3-methylcrotonyl CoA carboxylase deficiency detected by newborn screening program using tandem mass spectrometry. She was born at preterm, 36 weeks of gestation and her birth weight was 1,912 gm. She was delivered by Cesarian section due to maternal preeclampsia and oligohydramnios. An elevation of 3-hydroxyisovalerylcarnitine in a blood sample obtained at Seven days was detected by tandem mass screening. Massively elevated excretion of 3-hydroxyisovalerate and 3-methylcrotonylglycine was detected in the urine collected at 15 days. L-carnitine(100 mg/kg/day) was administrated orally to correct sencondary carnitine deficiency. Carnitine is conjugated with metabolites, to decrease the potential toxic effects. She is asymptomatic to date, and her growth and development are within normal limits.

BACKGROUND: Postoperative sore throat is a common complication of endotracheal intubation; the thicker the endotracheal tube, the higher the frequency of postoperative sore throat. So, we evaluated the effect of benzydamine hydrochloride spray on postoperative sore throat, associated with double-lumen endobronchial intubation. METHODS: Sixty patients undergoing thoracic surgery were scheduled and enrolled for intubation, with a double-lumen endobronchial tube. Of these patients, 30 were sprayed with benzydamine hydrochloride (group B), and 30 with normal saline (group N), 10 minutes before intubation was performed. Patients were randomly assigned to the two groups. Blood pressure and heart rate were recorded before, and after endotracheal intubation. Symptoms of sore throat, hoarseness, and dysphagia were examined one hour, as well as 24 hours, after surgery. RESULTS: Incidence of sore throat was 73.3% and 23.3% (P < 0.001) in groups N and B, respectively, at one hour after surgery. In addition, incidence of sore throat at 24 hours after the operation, was also statistically significant (66.6% and 20.0%, P = 0.001). Frequency of dysphagia at one hour, and 24 hours after surgery, was lower in group B. There were no significant differences in heart rate, blood pressure, and hoarseness at 24 hours after surgery between the two groups. CONCLUSIONS: In cases wherein a double-lumen endobronchial tube was used, an oropharyngeal spray of benzydamine hydrochloride before tracheal intubation, reduced incidence of postoperative sore throat.

PURPOSE: This study compared outcomes in children with acute leukemia who underwent transplantations with umbilical cord blood (UCB), bone marrow, or peripheral blood stem cells from a human leukocyte antigen (HLA)-matched related donor (MRD) or an unrelated donor (URD). METHODS: This retrospective study included consecutive acute leukemia patients who underwent their first allogeneic hematopoietic stem cell transplantation (HSCT) at Samsung Medical Center between 2005 and 2010. Patients received stem cells from MRD (n=33), URD (n=46), or UCB (n=41). RESULTS: Neutrophil and platelet recovery were significantly longer after HSCT with UCB than with MRD or URD (P<0.01 for both). In multivariate analysis using the MRD group as a reference, the URD group had a significantly higher risk of grade III to IV acute graft-versus-host disease (GVHD; relative risk [RR], 15.2; 95% confidence interval [CI], 1.2 to 186.2; P=0.03) and extensive chronic GVHD (RR, 6.9; 95% CI, 1.9 to 25.2; P<0.01). For all 3 donor types, 5-year event-free survival (EFS) and overall survival were similar. Extensive chronic GVHD was associated with fewer relapses (RR, 0.1; 95% CI, 0.04 to 0.6; P<0.01). Multivariate analysis showed that lower EFS was associated with advanced disease at transplantation (RR, 3.2; 95% CI, 1.3 to 7.8; P<0.01) and total body irradiation (RR, 2.1; 95% CI, 1.0 to 4.3; P=0.04). CONCLUSION: Survival after UCB transplantation was similar to survival after MRD and URD transplantation. For patients lacking an HLA matched donor, the use of UCB is a suitable alternative.
