PURPOSE: Neonatal hyperbilirubinemia has benign courses in most cases, but the possibility of toxicity of hyperbilirubinemia required courses examination of every newborn infant to identify the severity of hyperbilirubinemia progress. This study aims to see how the body surface area of newborns influences the decline rate of serum bilirubin level in conventional phototherapy. METHODS: Based on the charts of the Pediatrics Department, Dae-Dong Hospital from January 2003 to December 2006, we analyzed 168 neonates diagnosed as neonatal hyperbilirubinemia (serum bilirubin > or =15 mg/dL) in retrospective way. We excluded newborn infants under 37 weeks of gestation and under 2,500 g birth weight and classified neonates into four groups by the calculation results of body surface area:males above 75 percentile (group A), males below 25 (group B), females above 75 (group C), and females below 25 (group D). RESULTS: Out of 168 samples, the number of group A, B, C, D was 30, 20, 20, 15 respectively. In conventional phototherapy, the mean decline rates of serum bilirubin of group B and D recording 2.09 mg/dL/day and 1.77 mg/dL/day, were significantly faster than those of group A and C recording 1.63 mg/dL/day and 1.41 mg/dL/day (P<0.01). No significant differences were found in different duration of phototherapy between groups below 25 percentile and those above 75 in both genders. CONCLUSION: In conclusion, body surface area influences of infants the decline rate of serum bilirubin level in conventional phototherapy.

BACKGROUNDS: This study was performed to determine the onset time and dose of intranasal midazolam used for preanesthetic sedation in children. METHODS: The children were randomly allocated to recieve one of three medications via the nasal route in a double blind manner. Group I: patients were given normal saline 0.2 ml/5kg, Group II: patients were given midazolam 0.2 mg/kg, Group III: patients were given midazolam 0.3 mg/kg. RESULTS: The cardiovascular and SpO2 changes were not significantly different among the patients of the three groups. The sedation score was greater in group II compared with group I from 5 minute after administration (1.9 vs 2.7, p<0.05). postanesthetic recovery score (PARS) was not significantly different among the three groups. CONCLUSIONS: It is suggested that intranasal midazolam (0.2 mg/kg) produces anxiolysis and sedation in children with rapid onset.

The Diego blood group system consists of two pairs of antigens, Dia and Dib The incidence of Dia is low among pure Caucasian, Blacks, Polynesian and Eskimo, however, the rnongolians and American indians have both Dia and Dib. We report a case of two days old male who was admitted on first day of life for jaundice and subsquently exchange transfusion was performed on second day of life for bilirubin of 20 mg/dl. The blood groups of patient and his mother were both Rh D positive 0 type. Direct and indirect Coombstest were strong positive in the patient and indirect Coombstest was positive in his mother. We found anti-Dib antibody in his rnother's serum. The phenotype of Diego blood group system of the patient and his mother were Di (a+b+) and Di (a+b- ), respectively and hemolytic anemia in this case was due to anti-Dib antibody.

Tracheostomy refers to a surgical incision created in the neck to allow direct air entry into the trachea bypassing the upper respiratory tract including the oral and nasal cavities. Normal vocalization and swallowing are limited immediately postoperatively; however, gradual recovery of vocalization and swallowing function can be initiated, following improvement in the causative condition that necessitated the tracheostomy. Duration of the tracheostomy depends upon the patient’s condition, and the degree of vocalization and swallowing function recovery after tracheostomy tube removal varies widely across patients. In this review, we investigated the changes associated with vocalization and swallowing function in patients who underwent tracheostomy and have discussed the various approaches and voice rehabilitation treatments to aid with normal recovery.

BACKGROUND AND OBJECTIVES: The purpose of this study was to compare the usefulness of Cepstral peak prominence (CPP) with parameter of Multiple Dimensional Voice Program (MDVP) in evaluating unilateral vocal fold paraylsis patients with subjective voice impairment. MATERIALS AND METHODS: From July 2014 to August 2016, 37 patients with unilateral vocal fold paralysis who had been diagnosed with unilateral vocal fold paralysis and had received two or more voice tests before and after the diagnosis were evaluated for maximum phonation time (MPT), MDVP and CPP. Respectively. Voice tests were performed with short vowel /a/ and paragraph reading. RESULTS: The CPP-a (CPP with vowel /a/) and CPP-s (CPP with paragraph reading) of the Cepstrum were statistically negatively correlated with G, R, B, and A before the voice therapy. Jitter, Shimmer, and NHR of MDVP were positively correlated with G, R, B. Jitter, Shimmer, and NHR of the MDVP were significantly correlated with the Cepstrum index. G, B, A and CPP-a and CPP-s showed a statistically significant negative correlation and a somewhat higher correlation coefficient between 0.5 and 0.78. On the other hand, in MDVP index, there was a positive correlation with G and B only with Jitter of 0.4. CONCLUSION: CPP can be an important evaluation tool in the evaluation of speech in the unilateral vocal cord paralysis when speech energy changes or the cycle is not constant during speech.

BACKGROUND AND OBJECTIVES: The purpose of this study was to evaluate the impact of surgical extent on voice using acoustic and aerodynamic measurements in a serially followed thyroidectomy patients. MATERIALS AND METHOD: From October 2015 to January 2017, 108 patients who had undergone thyroid surgery and voice test for preoperative, 2, 3, and 6 months postoperatively were classified into five operative types. The radiological stage preoperatively and histopathological stage postoperatively were classified according to the invasion of thyroid capsule and surrounding tissue. For each classification, the results of the voice analysis according to the period were compared and analyzed. RESULTS: The difference of voice according to surgical extent, radiological stage, and histopathologic stage showed significant difference only with Maximal phonation time (MPT) over time. However, in the analysis of interaction between each classification and period, Phonation threshold pressure (PTP) only showed significant results. CONCLUSION: Differences in imaging and histopathologic stages have no significant effect on recovery of voice symptoms after thyroid surgery. As the extent of operation increases, the pressure to start vocalization is relatively higher, which also varies with time after surgery.

OBJECTIVES: Congenital muscular torticollis, a common disorder that refers to the shortening of the sternocleidomastoid in infants, is sensitive to correction through physical therapy when treated early. If physical therapy is unsuccessful, surgery is required. In this study, we developed a support vector regression model for congenital muscular torticollis to investigate the prognosis of the physical therapy treatent in infants. METHODS: Fifty-nine infants with congenital muscular torticollis received physical therapy until the degree of neck tilt was less than 5degrees. After treatment, the mass diameter was reevaluated. Based on the data, a support vector regression model was applied to predict the prognoses. RESULTS: 10-, 20-, and 50-fold cross-tabulation analyses for the proposed model were conducted based on support vector regression and conventional multi-regression method based on least squares. The proposed methodbased on support vector regression was robust and enabled the effective analysis of even a small amount of data containing outliers. CONCLUSIONS: The developed support vector regression model is an effective prognostic tool for infants with congenital muscular torticollis who receive physical therapy.

BACKGROUND: Hypothermia after induction of anesthesia results initially from core-to-peripheral redistribution of body heat. Both central inhibition of tonic thermoregulatory vasoconstriction in arteriovenous shunts and anesthetic induced vasodilation contribute to core-to-peripheral redistribution of heat. Ketamine increases peripheral arteriolar resistance uniquely; in contrast, propofol causes profound venodilatation that other anesthetics do not. The aim of the present study is to evaluate core temperature and skin-surface temperature gradients in use of ketamine for anesthetic induction compared with propofol in children. METHODS: Forty pediatric patients of ASA status I or II, undergoing elective surgery for strabismus or inguinal hernia were studied. The patients were allocated randomly to one of two groups: (i) GROUP P (n = 20): Anesthesia was induced with propofol and maintained with sevoflurane in combination with 60% nitrous oxide in oxygen. (ii) GROUP K (n = 20): Anesthesia was induced with ketamine and maintained with sevoflurane in combination with 60% nitrous oxide in oxygen. Core temperature, forearm skin temperature, fingertip skin temperature and Forearm minus fingertip, skin-temperature gradients were recorded before induction of anesthesia, 3 min after administering ketamine or propofol (just before endotracheal intubation), 5 min, and at 5-min intervals after induction of anesthesia. RESULTS: After induction of anesthesia, core temperature in the two groups was decreased but results did not differ significantly between two groups. Forearm skin temperature was increased significantly after 20 min of anesthesia in propofol group and 15 min of anesthesia in ketamine group, but results did not differ significantly between two groups. Finger tip skin temperature was increased significantly after 3 min of anesthesia in the propofol group and 10 min of anesthesia in the ketamine group. Finger tip skin temperature of 5 min of anesthesia in propofol group increased significantly greater than in ketamine group. Forearm minus finger skin surface temperature gradients was decreased statistically significantly at 3 min of anesthesia in the propofol group and 10 min of anesthesia in the ketamine group, gradients of 5 min of anesthesia was presented statistically significant between two groups. CONCLUSIONS: For pediatric patients, after induction of anesthesia with ketamine arteriovenous shunt vasomoter status was well maintained. And maintaining vasoconstriction during induction of anesthesia reduced the magnitude of redistribution hypothermia.

BACKGROUND: Vecuronium and Pancuronium have been proven to be associated with nicotinic receptor of skeletal muscle. Generally, nondepolarizing muscle relaxant is associated with contraction of smooth tracheal muscle, but there have been few studies about effects of nondepolarizing muscle relaxant on the smooth tracheal muscle. METHODS: We studied the acetylcholine dose response curve of the tracheal smooth muscle contraction and effects of propranolol, L-NAME after pretreating with vecuronium and pancuronium. RESULTS: Vecuronium shifted the acetylcholine dose-response curve of the tracheal contraction to the left, and pancuronium shifted the curve to the right. Vecuronium and Pancuronium reduced the contraction of smooth tracheal muscle with the use carbachol. Propranolol and L-NAME had no effect on the contraction of smooth tracheal muscle after pretreating with vecuronium and pancuronium. CONCLUSION: We suggest that vecuronium has an anticholinergic effect, while pancuronium has some effect on the muscarinic receptor in addition to its anticholinergic effect.
