PURPOSE: The pharmacologic effect of atropine on HPS can be considered to control pyloric muscle spasm. Therefore, we studied the effects of intravenous atropine sulfate on the clinical course of HPS, and periodically observed the ultrasonographic appearance of the pyloric muscles after atropine treatment. METHODS:From April 1998 to May 1999, 14 infants who were diagnosed with HPS were treated with intravenous atropine sulfate. Intravenous atropine sulfate was administered at an initial dose of 0.04mg/kg/day, which was divided into 8 equal doses. The daily dose was increased by 0.01 mg/kg/day until vomiting was controlled for an entire day while infants received unrestricted oral feeding. Ultrasonographic examinations were performed during hospitalization and repeated at least every 2 months until normalization of pyloric muscles was confirmed. RESULTS: Intravenous atropine was effective in 12 of 14 infants with HPS and the conditions of 9 of them improved. Two infants who were not free from vomiting despite a week of intravenous atropine sulfate treatment underwent pyloromyotomy. A series of ultrasonographic examinations were done after vomiting had improved with intravenous atropine sulfate. The ultrasonographic findings showed good passage of gastric contents through pyloric canals despite thickening of the pyloric muscles. CONCLUSION: Intravenous administration of atropine sulfate is an effective therapy for HPS and can be an alternative to pyloromyotomy. (J Korean Pediatr Soc 2000;43:763-768)

PURPOSE: To construct new Korean reference curves for birth weight by sex and gestational age using contemporary Korean birth weight data and to compare them with the Lubchenco and the 2010 United States (US) intrauterine growth curves. METHODS: Data of 2,336,727 newborns by the Korean Statistical Information Service (2008-2012) were used. Smoothed percentile curves were created by the Lambda Mu Sigma method using subsample of singleton. The new Korean reference curves were compared with the Lubchenco and the 2010 US intrauterine growth curves. RESULTS: Reference of the 3rd, 10th, 25th, 50th, 75th, 90th, and 97th percentiles birth weight by gestational age were made using 2,249,804 (male, 1,159,070) singleton newborns with gestational age 23-43 weeks. Separate birth weight curves were constructed for male and female. The Korean reference curves are similar to the 2010 US intrauterine growth curves. However, the cutoff values for small for gestational age (<10th percentile) of the new Korean curves differed from those of the Lubchenco curves for each gestational age. The Lubchenco curves underestimated the percentage of infants who were born small for gestational age. CONCLUSION: The new Korean reference curves for birth weight show a different pattern from the Lubchenco curves, which were made from white neonates more than 60 years ago. Further research on short-term and long-term health outcomes of small for gestational age babies based on the new Korean reference data is needed.

Interhemispheric approach has been accepted as a standard method approaching distal anterioir cerebral artery(DACA) aneurysm. In the approach, most authors use the surgical method retracting the superior sagittal sinus(SSS) after dural reflection. However, it results in limited surgical space and makes the surgical procedure difficult technically. To overcome the limitation, we tried to ligate and cut SSS in 13 patients out of 23 patients of DACA aneurysm from Mar. 1983 to Feb. 1993. Out of total 583 intracranial aneurysms operated on in that period, the proportion of DACA aneurysm was 3.95%. Mean age was 52.7 years ranging from 32 to 66 years. The sex ration was 7:16, showing female predominancy. As presenting symptoms, twenty two patients had subrachnoid hemorrhage and one patient had a third nerve palsy due to an unruptured posterior communicating artery aneurysm. On admission, 4 patients(17.4%) were in grade I, 10(43.5%) in grade II, 6(26.1%) in grade III, 3(13%) in grade IV according to the Hunt and Hess grading system. In 18 patients(78.3%), aneurysms were located at bifurcation of pericallosal and callosomarginal artery and in 5(21.7%) at bifurcation of frontopolar and pericallosal artery. Associated vascular anomalies were A1 hypoplasia(2 cases), multiple aneurysms(5 cases), fenestration of anterior cerebral(1 case) and arteriovenous malformation(1 case). Thirteen cases were operated on with ligation of the SSS and 10 without ligation. Overall surgical outcomes scored by Glasgow outcome scale were : 11 patients(47.8%) in Grade I, 6(26.1%) in Grade II, 2(8.7%) in Grade III, 4(17.4%) in Grade V. The outcomes in ligation group were : 8 patients(61.5%) in Grade I, 4(30.8%) in Grade II, 1(7.7%) in Grade III, and no death. The outcomes in non-ligation group were : 4 patients(40%) in Grade I, 1(10%) in Grade II, 1(10%) in Grade III, and 4(40%) in Grade V. These results showed that the patients operated on with ligation of SSS had more favorable outcomes than the patients without ligation. It seems that the SSS in the interhemispheric approach might provide several advantages and better operative outcome over the conventional method.

OBJECTIVES: This study was carried out to investigate the clinical availability of topographic auditory event related potential P300 as a biological marker in children with attention deficit hyperactivity disorder(ADHD). METHODS: The subjects were composed of children with ADHD(n=22:16 boys, 6 girl s:mean age=89.8+/-17.1months) and normal controls(n=20:12 boys, 8 girls:mean age=90.6+/-16.8months). Topographic auditory event related potential was measured by "oddball paradigm", and the latencies and amplitudes of P300 of both groups were determined by Global Field Power Measurement. After 8 weeks treatment with methylphenidate, P300 of ADHD children were also measured. RESULTS: Both P300 latency and amplitude were not different between ADHD children after treatment and normal controls, but significantly different between ADHD children before treatment and normal controls, and between before and after treatment of ADHD children. CONCLUSIONS: The results implicate that the latency and amplitude of P300 may be considered as state markers of ADHD.

OBJECTIVE: Attention-deficit hyperactivity disorder is a highly heritable psychiatric condition of early childhood onset characterized by marked inattention, hyperactivity and impulsiveness. Genes involved in catecholamine pathways, including catechol-O-methyltransferase (COMT), represent potential candidates, given that around 70% of children with ADHD show a symptomatic improvement when treated with methylphenidate, a psychostimulant. This study was designed to investigate the association of COMT polymorphism with ADHD in Korean population. METHOD: In this study, we used both family-based (the haplotype relative risk & the haplotype-based haplotype relative risk design) and case-control approaches to examine COMT polymorphism. The sample included 31 Korean children (25 males, 6 females) diagnosed as ADHD by DSM-IV, their 31 families with 31 mothers and 27 fathers and 106 normal controls. RESULTS: There were no differences of COMT genotype and allele frequencies between ADHD patients and control subjects. Also, there was no difference of COMT genotype between ADHD patients and HRR controls. The COMT1 allele frequencies of normal control group in Korean population (75%) was significantly different with that frequency of Caucasian population (50%). CONCLUSION: These results suggest that COMT polymorphism is not associated with ADHD in Korean population. However, the possibility of interacting effects of COMT with other genes or environment should be investigated.

Authors reviewed 37 cases of 25 patients with carpal tunnel syndrome treated surgically at Department of Neurosurgery of Kyung Hee University Hospital from January 1981 to February 1992. The sex ratio was 1:24 showing female predominancy. Distribution of age ranged from 26 years to 65 years. Duration of symptoms ranged from 15 days to 20 years. Tinel's sign was positive in 24 patients ans 10 patients had muscle atrophy. Twelve patients were operated on both hands, 7 patients on the right and 6 patients on the left. Operations were performed under the general anesthesia in 4 patients, under the axillary block in 3 patients and under the local lidocaine infiltration in 18 patients. In postoperative periods, 5 patients experienced transient aggravation of numbness of fingers, 1 patient had wound problem, 1 patient hypalgesia and 1 patient transient motor weakness which was thought to be due to residual effect of axillary block. Surgical outcomes were good in 35 cases(94.6%), fair in 1 case(2.7%) and poor in 1 case(2.7%).

The simultaneous occurrence of two distinct neoplasms derived from different cells of origin is sometimes recognized. In the thyroid gland, two such distinct tumors could consist of a concurrent medullary carcinoma composed of parafollicular C cells and well-differentiated carcinoma showing follicular epithelial cell differentiation. We report a rare, interesting case of concurrent medullary and papillary carcinoma of the thyroid gland. A 53-year-old female underwent total thyroidectomy and central neck dissection for medullary carcinoma of the left lobe of the thyroid gland, which was diagnosed by fine needle aspiration cytology and a high level of calcitonin. The left lobe showed a medullary carcinoma. The right lobe incidentally showed an papillary microcarcinoma. Two lymph nodes contain metastasis of medullary carcinoma. The two different tumor cells revealed the characteristic features of each on the microscopic, histochemical findings. We report a case of concurrent medullary and papillary carcinoma of the thyroid gland, with a review of the previously reported literature.

It has been known that dilated cardiomyopathy(DCM) is characterized by systolic dysfunction of left ventricle(LV), but there were few studies about correlation between LV systolic function, diameter and diastolic function measured by echocardiography and radionuclide ventriculography(RVG) The purpose of this study is to evaluate LV systolic and diastolic function as well as RV function using regional ejection fraction and functional images by RVG in 17 patients with DCM and to compare these variables with echocardiographic data. The results are as follows : 1) DCM showed diffuse systolic and diastolic dysfunction of LV. The systolic impairment is accounted for the diastolic impairment in DCM. 2) The increased standard deviation of phase angle of left ventricle(LVSDph) revealed LV asynchronous contraction in DCM. 3) LVSDph showed significant correlations with other RVG parameters such as LV ejection fraction, and peak ejection rate, peak filling rate and also with LV systolic and diastolic diameter measured by echocardiography. It is concluded that LVSDph may be useful in evaluation of LV systolic and diastolic function in patients with DCM as well as LV asynchronous contraction.
