PURPOSE: The residual intrahepatic stones with biliary strictures are difficult to remove percutaneously via T-tube tract after surgery in patients with recurrent pyogenic cholangitis. We evaluated the effectiveness of percutaneous balloon dilatation of benign biliary strictures. MATERIALS AND METHODS: The balloon dilatations with 6-12mm angioplasty balloon catheter and stone extractions were performed via a T-tube tract after surgical treatment in 15 patients with recurrent pyogenic cholangitis. The balloons were inflated for 3-4minutes under 5 atm. until disappearance of waist of the stricture site, from one to seven session. After balloon dilatation, residual stones were extracted with saline irrigation or stone basket. RESULTS: Among total 42 strictures, the balloon dilatation was succesful in 27 strictures(64.3%), partially successful in 12 strictures(28.6%), and failed in three strictures(7.1%). Single or central biliary strictures were dilated easily rather than multiple ductal strictures. Of 26 sites with residual intrahepatic stones, stone extraction was complete in 17 sites(65.4%), incomplete in seven sites(26.9%) due to impacted or large stone and acute ductal angulation, and failed in two sites(7.7%). CONCLUSION: Percutaneous balloon dilatation of benign biliary strictures is an effective procedure for extraction of residual intrahepatic stones associated with recurrent pyogenic cholangitis.

Although halothane is generally anesthetic of choice for asthmatics due to its bronchodilatory action, its combined use with aminophylline should be discouraged. This report is a 43-year-old male who had primary closure and open reduction internal fixation (ORIF) for facial avulsion injury and zygomatic tripod fracture under N2O-O2-halothane anesthesia. About 90 minutes after the procedure, the patient who had aminophylline infusion for an acute bronchospasm developed a sudden cardiac arrest. The immediate cardiopulmonary resuscitation was applied and the patient was recovered without any neurological deficit. At the time, the serum theophylline concentration of the patient was 16 microgram/ml which was in the range of normal therapeutic dose. The cause for this cardiac arrest by halothane is unknown, but possibly a drug interaction between halothane and aminophylline might have contributed, since halothane sensitizes the heart to exogenous catecholamines.

Split hand and split foot(SHSF) is a human developmental defect characterized by missing digits, fusion of remaining digits, and a deep median cleft resulting in a clawlike appearance of the hands and feets. SHSF is usually inherited in an autosomer dominant fashion. The incidence of SHSF is between 1/10,000 and 1/90,000. Thirteen cases of SHSF and chromosomal aberrations involving 7q21-22 have been described so far in the world. We experienced a case of typical tetramelic SHSF in neonate. Chromosome studies showed a pericentric inversion of chromosome 7:46,XY,inv(7) (p22q22). Inspection of the extremities and chromosome studies in the parents were normal.

BACKGREOUND: The hemodynamic responses to laryngoscopy and endotracheal intubation, tachycardia and arterial hypertension, are well known and should be minimized. The purpose of this study is comparison of effects of low-dose sufentanil and fentanyl on the changes of blood pressure and heart rate due to laryngoscopy and endotracheal intubation. METHODS: The cardiovascular responses were measured and compared in 60 patients, between 20~65 years old, ASA class I or II, undergoing elective operation pretreated with normal saline (n=20, control group), fentanyl 3 microgram/kg (n=20, fentanyl group), and sufentanil 0.6 microgram/kg (n=20, sufentanil group), respectively. Anesthesia was induced intravenously with pentothal sodium 4~5 mg/kg and endotracheal intubation was conducted after injection of succinylcholine 1 mg/kg. The changes of systolic arterial pressure, mean arterial pressure, diastolic arterial pressure, heart rate, and SpO2 (saturation of arterial oxygen) were measured at postsedation with pentothal sodium, 30 seconds, 1 minute, and 3 minutes following intubation. The variables of each group were compared with preinduction baseline values and fentanyl and sufentanil groups were compared with control group. Data were analyzed for statistical significance using repeated measures of ANOVA (analysis of variance). P<0.05 was considered statistically significant. RESULTS: The systolic and mean arterial pressures at 30 seconds and 1 minute and diastolic arterial pressure at 30 seconds after laryngoscopy and intubation in sufentanil group were significantly lower than values of control group (p<0.01). The heart rates at 30 seconds and 1 minute were significantly attenuated compared with control group (p<0.05). The blood pressures and heart rates of fentanyl group at 30 seconds after intubation were significantly attenuated compared with control group (p<0.05). CONCLUSIONS: The results suggest that pretreatment of fentanyl 3 microgram/kg and sufentanil 0.6 microgram/kg is effective to prevent the elevation of blood pressures and heart rates, and sufentanil 0.6 microgram/kg is more effective than fentanyl 3 microgram/kg to attenuate the hemodynamic changes due to laryngoscopy and intubation.

This article is to review various methods used to investigate internal and marginal adaptation of fixed dental prostheses, and to summarize a merit, worth, and limitation of each method, using some results of previous studies. The methods of measuring internal and marginal gap are divided into two categories in this study; in vivo and in vitro. In vivo methods are clinical evaluations, including exploration, radiography, and impression technique. In vitro methods are laboratory evaluations such as direct view, cross-sectioning, and silicone replica technique using microscope. Measuring by micro computed tomography (CT) or profilometer is also in vitro methods. In recent years, the development of scanning systems is able to analyze 3-dimensional internal and marginal space in detail. As measuring and analyzing technology become more advanced, the ability to thoroughly examine crown adaptation is becoming both simpler and more efficient.

PURPOSE: This study evaluated the clinical characteristics of brain tumors in children according to their location, the parental delay and the doctor's delay between the onset of symptoms and the diagnosis of a pediatric brain tumor. In addition, this study compared the relationship between the pre-diagnostic symptomatic interval and the tumor location. METHODS: A retrospective study was undertaken of 45 children with primary brain tumors admitted to Inha Hospital from July, 1986 to June, 2004. A diagnosis of the tumor location was made using brain MRI. RESULTS: The male to female ratio was 1:0.67. The median age at diagnosis was 6.0 years in supratentorial tumors, 7.0 years in infratentorial tumors. Twenty four cases(53.3 percent) were located in the supratentorial area, 21 cases(46.6 percent) were located in the infratentorial area. The distribution of supratentorial tumors were 14(58.3 percent) in the cerebral hemisphere and temporal lobe, seven (29.1 percent) in the suprasellar area, and three(12.5 percent) in the pineal gland and posterial lateral ventricle. The distributions of the infratentorial tumors were 12(57.1 percent) in the cerebellar vermis and fourth ventricle, four(19.1 percent) in the brain stem, and five(23.8 percent) in the cerebellar hemisphere. The most common initial symptom was seizure(37.5 percent) in the supratentorial tumor and headache(38.0 percent) in infratentorial tumors. The median pre-diagnostic symptomatic interval (PSI) was 21 days(range 0-240 days). The median PSI with a parental delay in supratentorial tumor was six days(range 1-240 days), and 30 days(range 1-40 days) in the infratentorial tumor. We immediately diagnosed most cases after visiting the hospital. There was no significant relationship between the tumor location and the pre-diagnostic symptomatic interval. CONCLUSION: The most common symptom of supratentorial tumors and infratentorial tumors was seizure and headache, respectively. Although, the median pre-diagnostic symptomatic interval was shorter than in previous studies, a detailed medical history and a correctly interpreted neurological examination should lead to an earlier diagnosis of pediatric brain tumors.

OBJECTIVE: There is no acceptable indication and treatment of choice for infantile and child subdural hygroma and there are only a few reports about that in Korea. So the authors studied the clinical findings of infantile and child patients with subdural hygroma to improve the understanding and to suggest a standard treatment method. METHODS: The authors retrospectively evaluated the causes, preoperative symptoms, radiological thicknesses, and postoperative results of 25patients with subdural hygroma who received surgical therapy. RESULTS: There were 16boys and 9girls whose median age was 6months(range 2~120months). The main clinical manifestations were seizures, increased intracranial pressure, macrocrania and alteration of consciousness. Radiological thicknesses of the subdural hygroma varied from 7mm to 42mm and postoperative changes of thickness(y) could be expressed with the factor of month(x): y = -1.32 x +11.8 in subdural drainage, and y = -1.52 x +14.9 in subduroperitoneal shunts. Of the 25patients, 2 (50%) were successfully treated by aspiration, 13 (59%) by subdural drainage, and 9 (69%) by subduroperitoneal shunt. CONCLUSION: It is suggested that the diagnosis and treatment of subdural hygroma in infants and children should be carefully addressed because of its high prevalence in children, and especially in infants. It is also suggested that the subdural drainage could be primary initial treatment method because it is simpler than a shunt, and since our data show that there is no statistical difference in postoperative recovery duration between the two operative methods.
