BACKGROUND: Otitis media with effusion(OME) is a very common disease in pediatric age. However, a few literatures on epidemiologic study of otitis media with effusion are available in Korea due to the great variability of its diagnostic criteria and clinical features. The aim of this study is to provide the estimate of silent otitis media prevalence for preschool age. METHODS: The study population includes 329 children enrolled in 6 kindergartens in Kunsan city from April 1 to 10, 1995. Silent otitis media was diagnosed with otoscopy, pneumatic otoscopy and impedance audiometry by DANAC 40 model impedance audiometer from DANA JAPAN Co. RESULTS: The prevalence of silent otitis media with effusion was 14.5% and peak at 6 years of age(17.8%).The prevalence of silent otitis media with effusion according to sex were 11.8% in boys group, 17.9% in girls group. Nine cases(11.8%) involved bilaterally. Forty three cases(89.6 %) were asymptomatic cases. CONCLUSIONS: Among 329 preschool children, the prevalence of silent otitis media with effusion was 14.5%. The prevalence by sex showed slightly higher in girls group than boys group. OME involved unilateral site mostly and subjective symptoms were rare.

The PMT-air airplane crash accident occurred in June 25, 2007 in Sihanoukville, Cambodia. All 22 passengers and crew, including 13 Korean victims, were found dead. Human identification was done at the Cambodian-Russian Soviet friendship hospital. All of Korean victims were identified with fingerprint comparison, age estimation, comparison of belongings and examination of past medical history. In this identification process, the examination of antemortem data source with searching personal blog of internet had been proved efficient in human identification. The antemortem data collection with internet access may be useful and should be combined with classical antemortem data collection process because it is beyond spatial and time limitation.

PURPOSE: Combined chemoradiotherapy is standard management for locally advanced non-small cell lung cancer (LA-NSCLC), but standard treatment for elderly patients with LA-NSCLC has not been confirmed yet. We evaluated the feasibility and efficacy of concurrent chemoradiotherapy (CCRT) for elderly patients with LA-NSCLC. MATERIALS AND METHODS: Among patients older than 65 years with LA-NSCLC, 36 patients, who underwent CCRT were retrospectively analyzed. Chemotherapy was administered 3-5 times with 4 weeks interval during radiotherapy. Thoracic radiotherapy was delivered to the primary mass and regional lymph nodes. Total dose of 54-59.4 Gy (median, 59.4 Gy) in daily 1.8 Gy fractions and 5 fractions per week. RESULTS: Regarding the response to treatment, complete response, partial response, and no response were shown in 16.7%, 66.7%, and 13.9%, respectively. The 1- and 2-year overall survival (OS) rates were 58.2% and 31.2%, respectively, and the median survival was 15 months. The 1- and 2-year progression-free survivals (PFS) were 41.2% and 19.5%, respectively, and the median PFS was 10 months. Regarding to the toxicity developed after CCRT, pneumonitis and esophagitis with grade 3 or higher were observed in 13.9% (5 patients) and 11.1% (4 patients), respectively. Treatment-related death was not observed. CONCLUSION: The treatment-related toxicity as esophagitis and pneumonitis were noticeably lower when was compared with the previously reported results, and the survival rate was higher than radiotherapy alone. The results indicate that CCRT is an effective in terms of survival and treatment related toxicity for elderly patients over 65 years old with LA-NSCLC.

OBJECTIVE: Although there are a few studies reporting the efficacy of moclobemide in the treatment of social phobia, it has been poorly studied in Korea. The purpose of this study was to investigate the short term efficacy of moclobemide in Korean patients with social phobia. METHOD: Sixty six patients with social phobia based on DSM-IV criteria were enrolled to 4-week trial with a flexible-dose regime of moclobemide. Treatment responses were assessed at baseline and week 4 with Liebowits Social Anxiety Scale (LSAS), Brief Fear of Negative Evaluation (BFNE), Mattick's Social Phobia Scale, Beck Depression Inventory (BDI), and Sheehan's Disability Scale (SDS). RESULT: Thirty eight of 66 patients completed the 4-week trial. Scores of LSAS, BFNE, and Mattick's Social Phobia Scale at baseline were not significantly reduced after 4-week trial (p=0.084, p=0.537, p=0.283, p=0.111, respectively). But scores of BDI and 3 of 4 Sheehan's Disability Subscale at baseline were significantly reduced (p=0.026, p=0.000, p=0.005, p=0.002, respectively). CONCLUSION: Overall results of preliminary study showed that moclobemide could be used for the treatment of depression and functional impairment, but that it was not effective for treatment of anxiety and phobic avoidance of social phobic patients. More controlled, long-term studies are needed to evaluate the efficacy of moclobemide for treatment of social phobia.

We saw a case of minoxidil induced pericardial effusion in a 36 years old female who developed generalized edema, weakness and hypertrichosis after taking minoxidil for 1 year. Her chest PA showed globular shaped cardiac enlargement and pulmonary congestion. Echocardiography of the heart showed moderate amount of pericardial effusion. 10 days later after cessation of the drug administration and conservative managements, her chest PA showed marked improvement of heart size and pulmonary congestion. 20 days later her blood pressure became normal with the continued use of other antihypertensive drugs.

OBJECTIVES: Disabilities in patients with panic disorder are well known for their acute and severe anxiety symptoms. Disabilities in patients with social phobia are not often rewgnied because symptoms are misattributed to simple shyness. We compared the severity and areas of disabilities among social phobia and panic disorder patients. METHODS: The study participants were 53 patients with social phobia and 55 patients with panic disorder, diagnosed by MINI-Plus (Mini International Neuropsychiatric Interview-Plus) and SDS (Sheehan disability scale). RESULTS: Compared with panic disorder patients, the patients with social phobia showed significantly greater impairments in work and social subscales of SDS. However, the home disability subscale scores of the patients with panic disorder were higher than the patients with social phobia. The general disabilities and GAF (General Assessment Functioning) scores were not different signigicantly. Comorbid cases have shown to induce more dysfunctions in work and social areas, except home and leisure areas, irrespective of diagnoses. CONCLUSION: Overall disabilities in patients with social phobia and panic disorder were not different significantly. But the disabilities were different accordiny to the areas, and the differences correlate with the specific symptoms.

The authors introduced a new approach for clipping of the incidental aneurysm of the middle cerebral artery (MCA) and reported the clinical results. We retrospectively reviewed 26 patients with 27 incidental MCA aneurysms who were treated from January 2010 to December 2012. All clippings were performed through a small temporal craniotomy and linear skin incision. Follow-up imaging showed complete occlusion of 26 aneurysms (96.3%), residual neck in one (3.7%). In one case, residual neck of the aneurysm did not grow on serial follow up. In one of 26 cases (3.8%), approach-related complication was retraction injury of the temporal cortex. Two patients developed postoperative infarction on the MCA territories due to vasospasm and on the cerebellum due to unknown causes. These were not approach-related complications. Operation time was 95 min-250 min (mean 143 min). There were no complications of temporal muscle atrophy, scar deformity, paresthesia, or pain around the scalp incision and frontalis palsy. This approach offers good surgical possibilities and little approach related morbidity in the clipping of incidental MCA aneurysms.

Malignant intracranial meningioma is a rare pathologic entity. Although the topic is widely discussed, there is little agreement in the literatures as to the histological and radiological features that warrant the diagnosis of malignant meningioma. An osteolytic lesion of the skull may have been suggested in several cases. But in adults, the most commonly suspected lesion is metastatic lesion;while meningioma is rarely suspected. Meningiomas are occasionally associated even with extracranial masses. However, most of these masses are firm, and are caused by hyperostosis. Extracranial soft-tissue masses rarely arise in meningiomas, thus, the presence of both osteolytic skull lesion and soft-tissue mass is exceedingly rare in meningiomas. The authors report a case of osteolytic malignant meningioma located at the frontal fossa extending to the subgaleal space appearing as an extracranial soft-tissue mass in a 19-year-old female. The clinical, radiological, neurosurgical, and histopathological features of these lesions are discussed together with a review of the literatures.

PURPOSE: The purpose of this study was to compare the efficacy of curative emergency surgery for complicated colon cancer in terms of tumor recurrence and survival compared with that of elective surgery. METHODS: A total of 238 primary surgeries for colon cancer were performed. All patients were deemed to have undergone a curative resection. Patients were classified into an emergency surgery group for complicated colon cancers (n=40) and an elective surgery group for uncomplicated colon cancers (n=198). RESULTS: Emergency colonic cancers present at a more advanced stage (P=0.002). The postoperative mortality rate in the emergency group was significantly higher than it was in the elective group (15.0% vs. 2.5%, P= 0.004). There were differences between the two groups in tumor recurrence (32.5% vs. 13.1%, P=0.003), overall survival (52.5% vs. 71.7%, P=0.017), and disease-free survival (50.0% vs. 69.7%, P=0.016). However, after the patients were stratified according to tumor stage, no statistical differences were observed. CONCLUSIONS: When compared with uncomplicated colon cancers, complicated colon cancers present at a more advanced stage with a higher postoperative mortality and an overall worse prognosis. However, the difference decreases when patients are stratified according to the tumor stage. The negative prognostic efficacy of emergency surgery for complicated colon cancers appears to be confined to the perioperative period. Despite the more advanced stage of tumors in patients undergoing emergency surgery, the aim of the surgeon should be to offer a curative resection for better survival, if possible.

The pathogenesis of juxtafacet cysts is closely related to degenerative instability of the lumbar spine and degenerative changes in the ligamentum flavum and the facet joint. A 56-year-old man presented with severe right thigh pain and numbness for 1 month after a laminar fracture of the L4 spine. Magnetic resonance imaging revealed a heterogenous cystic mass surrounding the facet joint between the fourth and fifth lumbar vertebrae on the right side. Conservative therapy was unsuccessful and the lesion was removed by surgical decompression alone without fusion. The histological examination showed a fragmented, cystic wall-like structure composed of myxoid degenerative tissue without lining epithelium. Here we present this case of a ganglion cyst that appeared to be associated with facet joint instability.
