We report a rare case of third cranial nerve palsy due to a ruptured left internal carotid artery (ICA) bifurcation aneurysm. A 70-year-old man was stuporous with left ophthalmoplegia (unilaterally fixed dilated pupil, abducted eyes, and ptosis). A computed tomography demonstrated extensive hemorrhage spreading around the left sylvian fissure and basal cistern with a ipsilateral predominance, and intraventricular hemorrhage without focal mass effect. A computed tomographic angiography demonstrated a 3mm sized aneurysmal sac which arose from the left ICA bifurcation. The aneurysmal clipping was performed at 1 day after onset. In operative field, there was no direct compression of the oculomotor nerve by the aneurysmal fundus. Postoperatively, he recovered to alert mental status, but left ophthalmoplegia recovered partially at the 1 year follow-up.

OBJECTIVE: To identify the risk factors for secondary lymphedema after breast cancer surgery. Lymphedema, a sequelae of breast cancer therapy, changes functional abilities and may affect a patient's psychosocial adjustment and overall quality of life. It is generally underreported and undertreated. METHOD: Six hundred two patients who had undergone breast cancer surgery between January 2000 and December 2005 were examined. The circumferences of the upper extremities were measured and lymphedema was defined as difference of greater than 2cm between the affected and normal arms. The effects of age, body mass index, diabetes, hypertension, side of tumor, sugery method, radiotherapy, chemotherapy, TNM stage, involvement of axillary lymph nodes, menopausal state and laboratory findings on the development lymphedema were investigated and analyzed by t-test, chi-square test and multiple logistic regression analysis. RESULTS: 121 out of 602 patients had lymphedema. Those patients with lymphedema had a higher body mass index. Univariate analysis indicated an increased occurrence of lymphedema due to those with body mass index, radiotherapy, T2 stage, N3 stage and axillary lymph node invasion. Multivariate analysis revealed that body mass index and radiotherapy were independently associated factors for lymphedema after breast cancer surgery. CONCLUSION: The patients who had radiotherapy or BMI greater than 25 must be considered as potential candidates to have lymphedema after breast cancer surgery. Therefore, these patients should be informed during the follow-up period about this morbidity, the preventive measure, and the treatment.

PURPOSE: To examine how SCUBA diving activities in high-pressure underwater environment affect their intraocular pressure (IOP), visual field (VF), retinal nerve fiber layer (RNFL), and the shape of optic disc. METHODS: We performed visual acuity and refractory test, IOP test, VF test, RNFL photography, optical coherent tomography, and 3D optic disc photography for a group of 32 people and a control group of 32 non-divers, and analyzed the differences between the two groups. For the diver group, we conducted a questionnaire survey on the patterns of diving and diving experience, and analyzed their correlation with results of test. RESULTS: Compared to the Control, the diver group showed significant difference in the mean IOP (diver group: 15.71 +/- 2.54 mmHg, control group: 14.23 +/-2.15 mmHg, p = 0.019), and abnormal visual field (diver group: 7 eyes (11.3%), control group: 0 eye (0%), p = 0.006). 85.7% of abnormal visual field belonged to early defect. The diver group did not showed significant difference in the shape of optic disc (p = 0.546), but the optic nerve atrophy in shape of optic disc test field (diver group: 8 eyes (12.9%), control group: 2 eyes (3.1%), p = 0.042) was significantly different. CONCLUSIONS: Divers who did SCUBA diving activities need to have a glaucoma test regularly. Additional research and large cross or longitudinal study are needed to evaluate causes that scuba diving activities affect.

PURPOSE: To develop a protocol for treatment of injuries to lacrimal punctum and canaliculus associated with eyelid burns. METHODS: We retrospectively reviewed the records of seven patients who required the treatment of punctal and canalicular injuries caused by medial eyelid burns. RESULTS: Four patients were treated with punctoplasty and bicanalicular silicone tube intubation within 3 weeks of injury. One patient was treated at 2 months and punctum of upper eyelid was not found, requiring punctoplasty and monocanalicular silicone tube intubation of lower eyelid. Silicone tube removal was performed over a range of 3 to 6 months. Two patients were treated after 3 months of injury by conjunctivodacryocystorhinostomy. Six patients showed good passage by syringing after surgery. CONCLUSIONS: Early evaluation and treatment of canalicular burn injuries can avoid complex surgical procedures such as conjunctivodacryocystorhinostomy, and silicone tube removal is recommended before 6 months after surgery.

OBJECTIVES: Recent studies have focused on characteristics of adolescents who use internet addictively. Due to many ambiguities in the definitions of internet addiction, it is hard to find a tool for diagnosing internet addiction. In this study, we attempt to identify the temperamental characteristics of adolescents who have addictive internet using patterns by administering a newly developed internet addiction scale based on a psychometric technique and temperament and character inventory (TCI) based on Cloninger's psychobiological model. METHODS: Participants were 566 high school students. 478 students were recruited from high schools, and 88 were selected from internet cafes. We applied the internet addiction scale and TCI. All the students were divided into 3 groups (high risk user group, potential risk user group and normal user group) according to the results of the internet addiction scale. TCI scores were compared and analyzed according to the participants' characteristics. RESULTS: There were significant differences in the distribution of internet user group according to gender. Boys had higher percentage of high risk and potential risk users than girls. When each TCI score was compared according to gender, girls showed significantly higher harm avoidance, reward dependence, cooperativeness scale scores and lower persistence, self-transcendence scale scores than boys. TCI scores were compared among the internet addiction risk user groups. Risky internet users showed lower scores in reward dependence, self-directness and cooperativeness dimensions than normal internet users. CONCLUSION: There was a gender difference in internet addiction risk in this study. These results suggest that adolescents who use internet addictively also have higher tendency of problematic social and interpersonal relationship. These tendencies need to be considered as one of the important aspects of internet addiction. This study shows that assessment of temperament and character in adolescents who have problems related to the internet may be needed for understanding their addiction behaviors and underlying psychopathologies.

PURPOSE: Segmental parenchymal excretion delay on Tc-99m DISIDA scan is caused by intrahepatic bile duct obstruction. However, the diagmostic value for intrahepatic bile duct obstruction is unknown. We conducted this study to assess the positive predictive value of segmental excretiom delay for the diagnosis of intrahepatic bile duct obstruction, and additional benefit over other noninvasive radiologic studies. MATERIALS AND METHODS: The study population consisted of 43 patients (48 scans) Who showed segmental parenchymal excretion delay on Tc-99m DISIDA scan. The results of abdominal CT or ultrasonography, which was done within 1 month of Tc-99m DISIDA scan, were compared with scintigraphic findings. RESULTS: The etiology of segmental parenchymal excretion delay was determined by ERC or PTC in 31 scans, and follow-up studies in 13 scans. No causes were identified in 4 scans. The positive predictive value of segmental parenchymal excretion delay for intrahepatic bile duct obstruction was 92% (44/48). On the other hand, 13% (5/38) of CT and 28% (5/18) of ultrasonography were normal. In 18% (7/38) of CT and 17% (3/18) of ultrasonography, only intraheipatic bile duct dilatation was noted without any diagnostic findings of intrahepatic bile duct obstruction. CONCLUSION: Segmental parenchymal excretion delay on Tc-99rn DISIDA scan had a high positive predictive value for the diagnosis of intrahepatic bile duct obstruction. Tc-99m DISIDA scan may be useful for the diagnosis of intrahepatic bile duct obstruction, especially in patients with nondiagnostic CT or ultrasonography. The diagnostic usefulness need to be confirmed by further prospective studies. KW: Tc-99m DISIDA, Segmental parenchymal excretion delay, Intrahepatic bile duct obstruction.

To evaluate the change of colloid osmotic pressure(COP) and the correlation between COP and other parameters during pediatric open heart surgery at Seoul National University Children's Hospital, COP, protein, albumin, hemoglobin, and hematocrit, were measured immediately after induction(T1), before cardiopulmonary bypass(CPB)(T3), duringT4, T5), and after bypass(T.6, T7) and immediately after(T8) and 24 hour after(T9) arrival at intensive care unit (ICU) in l0 pediatric patients aged from l year to 13 years. Above parameters of priming solution(T2) were also measured. The results were as followings; l) The good correlation between COP and protein(r=0.87), albumin(r=0.86), hemoglobin(r=0. 80), hematocrit(r=0.77) were showed. 2) The COP of priming solution was 9.42.6 mmHg and this was definitely lower than normal value. 3) The COP during CPB was in the range from 11 to 12 mmHg(mean values) and this value was also significantly lower than normal value. 4) The COP increased from the time of weaning from CPB, but the COP at the arrival at ICU was 18.0+/-1.2 mmHg and this value was still significantly lower than normal value. 5) The COP at 24 hours after arrival at ICU was 21.7+/-1.2 mmHg and this value was not significantly different fron normal value. Thus, the results suggest that the priming solution shuold be improved to maintain COP during and immediatelt after CPB.

PURPOSE: We studied the clinical outcome of nasolacrimal probing according to the age and silicone tube intubation for congenital nasolacrimal duct obstruction. METHODS: We analyzed a total of 76 patients (99 eyes) who had undergone nasolacrimal duct probing performed in the office under topical anesthesia and 18 patients (20 eyes) who had undergone silicone tube intubation under general anesthesia between February 1997 and March 2001. Patients who had undergone probing were grouped according to their age at the time of probing: 6 months or less (group 1), 7 to 12 months (group 2) and 13 months or older (group 3). RESULTS: The overall success rate by probing was 84%. The success rate of probing in those under 6 months of age was 88%; in those from age 7 to 12 months, 86%; and in those 13 months or older, the rate decreased to 76%. The decrease in success rate after 13 months was statistically significant (P<0.05). The success rate of silicone tube intubation was 95%. CONCLUSION: We concluded that early office probing under 12 months of age for congenital nasolacrimal duct obstruction is an effective method for treatment of symptomatic nasolacrimal duct obstruction. In case over 13 months of age, probing is also considered as the first choice of treatment although its success rate is lower than the former. Silicone tube intubation is an effective method in case of failure of repeated probing and over 20 months of age.
