Traumatic rupture of the superior oblique muscle is rare. We report a case of a 54-year-old man injured by the metal hook of a hanger, resulting in a rupture of the superior oblique muscle tendon. He complained of torsional diplopia when in the primary position. The distal margin of the superior oblique muscle was reattached to sclera 5 and 9 mm apart from the medial insertion of the superior rectus muscle. One week after the operation, torsional diplopia disappeared. However, a 4-prism diopter ipsilateral hypertropia was observed. Three months later, hypertropia gradually increased to 20 prism dioptors and the second operation was done to correct vertical diplopia.

OBJECTIVES: The objective of this study was to assess the characteristics of smartphone use in elementary school children and the emotional and behavioral problems associated with smartphone overuse and addiction. METHODS: Children referred to a community based pediatric mental health center were screened for smartphone addiction and related problematic behavior using the Smartphone Addiction Proneness Scale and the Korean version of the Child Behavior Checklist (CBCL). RESULTS: 1) Statistically significant differences in gender, usage time, ownership, and internalization symptoms (somatization, anxiety/depression, withdrawal) were observed between the smartphone excessive user group and the control group. 2) Variants showing the most significant correlation with smartphone addiction were usage time, internalization problems somatization, anxiety/depression, withdrawal, aggressive behaviors, and total behavior problems. CONCLUSION: The results of this study indicated an association of addiction tendency in elementary school children with internalization symptoms. Close observation in the familial and academic setting may be important for children at high risk for smartphone addiction.

BACKGROUND: Advanced age alone should not be a serious deterrent to surgery. Preoperative evaluation of concomitant illness, operation time, accurate and minimal, but adequate surgery will serve to minimize morbidity and mortality in elderly patients. METHODS: The total number of surgical patients admitted to Kwang Hye Hospital, Pusan, from March 1994 to August 1996 was 3211, and the number of surgical geriatric patients admitted during the same period was 214. Operations were performed on 139 patients. We recorded information about age, sex, anesthesia type, operation time, non malignancy vs malignancy, emergency vs elective "Surgery", coexisting disease, and APACHE II score, and we examined the patients for results affecting postoperative morbidity and mortality. RESULTS: Postoperative complications occured in 55 cases (39.6%), and the operative mortality was 2.2%. The significant factors affecting postoperative morbidity were emergency operation, malignancy and APACHE II score. The operation time and coexisting diseases were not significant. Age had little effect on the postoperative prognosis CONCLUSIONS: Performance of elective surgery and preoperative evaluation of the APACHE II score are important factors.

The types of K+ channel which determine the pattern of spontaneous action potential (SAP) were investigated using whole-cell variation of patch clamp techniques under current- and voltage-clamp recording conditions in rat clonal pituitary GH3 cells. Heterogeneous pattern of SAP activities was changed into more regular mode with elongation of activity duration and afterhyperpolarization by treatment of TEA (10 mM). Under this condition, exposure of the class III antiarrhythmic agent E-4031 (5 micrometer) to GH3 cells hardly affected SAP activities. On the other hand, the main GH3 stimulator thyrotropin-releasing hormone (TRH) still produced its dual effects (transient hyperpolarization and later increase in SAP frequency) in the presence of TEA. However, addition of BaCl2 (2 mM) in the presence of TEA completely blocked SAP repolarization process and produced membrane depolarization in all tested cells. This effect was observed even in TEA-untreated cells and was not mimicked by higher concentration of TEA (30 mM). Also this barium-induced membrane depolarization effect was still observed after L-type Ca2+ channel was blocked by nicardipine (10 micrometer). These results suggest that barium-sensitive current is important in SAP repolarization process and barium itself may have some depolarizing effect in GH3 cells.

PURPOSE: Little data is currently available on the use of the impulse oscillometry system (IOS) parameter in analyzing the lung function of young children with cough-variant asthma (CVA) and classic asthma. The aims of this study were to evaluate the bronchial responsiveness between patients with CVA and those with classic asthma using dose-response slope and various cutoff values. METHODS: A methacholine challenge test and a pulmonary function test were performed in 43 children with classic asthma and 26 children with CVA using IOS, and the respiratory resistance (Rrs) and reactance (Xrs) were obtained. The bronchial responsiveness were assessed by provocative concentration causing an 80% fall from baseline in reactance at 5 Hz (PC80_Xrs5) and a 40% increase in resistance at 5 Hz (PC40_Rrs5) and calculating from the degree of dose-response slope (DRS) for airway resistance and reactance. RESULTS: There was no significant difference in base lung function between the two groups. However, the mean DRS_Xrs5 and the number who showed more than an 80% fall in reactance were significantly higher in classic asthma group than those in CVA group (P=0.040 and P=0.040, respectively). CONCLUSION: The use of DRS in oscillatory reactance at 5 Hz is useful for the differential diagnosis of classic asthma and CVA based on bronchial hyperresponsiveness.

BACKGROUND: Portable cardiopulmonary bypass (CPB) technique has been used increasingly as a potent and effective option for emergency cardiopulmonary resuscitation (CPR) because it can maintain more stable hemodynamics and provide better survival than conventional CPR techniques. This study was designed to develop a prototype of Korean portable CPB system and, by applying it to CPR, to discriminate whether it would be superior to standard open-chest CPR. MATERIAL AND METHOD: By using adult mongrel dogs, open-chest CPR (OCPR group, n=4) and portable-CPB CPR (CPB group, n=4) were compared with respects to restoration of spontaneous circulation (ROSC), hemodynamics, effects on blood cells, blood gas patterns, biochemical markers, and survivals. Ventricular fibrillation-cardiac arrest (VF-CA) of arrest (VF-CA) of 4 minutes followed by basic life support (BLS) of 15 minutes was applied in either group, which was standardized by the protocol of American Heart Association. Then, advanced life support (ALS) was applied to either group under the support of internal cardiac massage or CPB. ALS was maintained until ROSC was achieved but not longer than 30 minutes regardless of the presence of ROSC. All of the measured values were expressed as means+/-SD percent change from baseline. RESULT: During the early ALS, higher mean arterial pressure was maintained in CPB group than in OCPR group (90+/-19 vs. 71+/-32 %; p<.05) and lower mean pulmonary arterial pressure was also maintained in CPB group than in OCPR group (105+/-24 vs. 146+/-6%; p<.05). ROSC was achieved in all dogs. Post-ROSC levels of hematocrit, RBC, and platelet were decreased and plasma free hemoglobin was increased significantly in CPB group compared to OCPR group (p<.05). Changes in blood gas patterns, lactate, and CK-MB levels were not different between groups. Early mortality was seen in 3 dogs in OCPR group (survival time 31+/-36 hours) and 2 in CPB group (228+/-153 hours, p=ns). The remainders in both groups showed prolonged survival. CONCLUSION: These findings indicate that portable CPB can be effective to maintain stable hemodynamics during cardiac arrest, to achieve ROSC and to prolong survival. Further study is needed to refine the portable CPB system and to meet clinical challenges.

There are several antigenic variants of Orientia tsutsugamushi. The 56-kDa type-specific antigen (TSA) is responsible for the antigenic variation. Nucleotide sequences of the 56-kDa TSA obtained from 44 eschar samples of Korean scrub typhus patients and from 40 representative strains retrieved from the GenBank database were analyzed phylogenetically. Clinical patient data were assessed based on the genotyping results. Of the 44 nucleotide sequences, 32 (72.7%) clustered with the Boryong genotype, which is the major genotype in Korea. Eleven nucleotide sequences (25%) clustered with the Kawasaki genotype, not identified in Korea until 2010. One nucleotide sequence was consistent with the Karp genotype. The clinical course of the patients infected with each genotype showed no differences. Diagnostic performance of the immunofluorescence assay (IFA) using the 56-kDa TSA from Gilliam, Karp and Boryong as test antigens were not different for the Boryong and Kawasaki genotypes. Although Boryong is still the predominant genotype, the results suggest that Kawasaki genotype is quite prevalent in Chungbuk province of Korea.
