Vertigo mimicking labyrinthine lesions may have resulted from ischemic insult to the inner ear or the vestibular nerve and nucleus in the AICA infarction syndrome. A 56-year-old female was admitted to the emergency room with vertigo and hearing loss in right ear. On neurological examination, she had left beating jerky torsional and horizontal nystagmus with falling and past pointing to right side. Brain magnetic resonance images showed high signal intensity in anterolateral portion of inferior pons on T2- weighted images. Severe right facial palsy of peripheral type developed 24 hours after admission. Audiometry and electronystagmography documented absent auditory and vestibular function on the affected side. We argue that vertigo of the acute infarction in AICA territory can be involved the eight and seventh nerve root entry zoon and mimic labyrinthine lesions

Authors examined 40,000 minifilms(boys and girls each 10,000 in junior and senior high schools) which were taken for survey of pulmonary tuberculosis for junior and senior high school students and checked the prevalence of scoliosis. It was considered lateral curvature of spine more than 10 degrees as nonpostural scoliosis, which were analyzed prevalence rate, degree of curvature, distribution of size of curvature, pattern of curve and direction of curvature. Following results were obtained. 1. The overall prevalence rate was 1.56; male 1.38. and female 1.70%(Junior high school 1.06%, Senior high school 2.05%). 2. Scoliosis secondary due to bony abnormality was found in 5 cases. 3. The most common pattern of curvature was the thoracic curve. 4. In sihgle curve, right to left ratio was 1.7, especially senior high school girls had more right curve and junior high school boys had more left curve. 5. The prevalence of senior high school students was greater than that of junior high school students and the degree of curvature was also severe in senior high school students than in junior high school students.

BACKGROUND: Diagnosis of tuberculous pleurisy is sometimes difficult using conventional diagnostic methods. We have investigated the utility of pleural fluid cell IFN-gamma production assay in the diagnosis of tuberculous pleurisy. METHODS: We prospectively performed pleural fluid cell IFN-gamma production assay in 39 patients with tuberculous pleural effusions (TPE) and in 26 patients with nontuberculous pleural effusions (NTPE) (13 malignant pleural effusions and 13 parapneumonic effusions). Pleural fluid cells were cultured in DMEM media and stimulated with purified protein derivatives (PPD), and phytohemagglutinin (PHA) for 24 hr. The amount of IFN-gamma released in the culture supernatant was quantitated by IFN-gamma ELISA assay. We have also measured adenosine deaminase (ADA) activities and IFN-gamma concentrations in the pleural fluid. RESULTS: 1) The pleural fluid levels of ADA activity and IFN-gamma concentrations were significantly higher in TPE than NTPE (p<0.01). 2) IFN-gamma production in TPE cells stimulated by PPD (755,266+/-886,636 pg/ml) was significantly higher than NTPE cells (3,509+/-6,980 pg/ml) (p<0.01). By considering the fact that IFN-gamma concentrations over 10,000 pg/ml is a criteria for the diagnosis of TBE, sensitivity and specificity of the test were 97.4 and 92.3%, respectively. 3) The ratios of IFN-gamma production by the stimulation with PPD and PHA (PPD/PHA) were significantly higher in TPE cells (59+/-85) than NTPE cells (5+/-18)(p<0.01). Considering the criteria for the diagnosis of TBE as PPD/PHA ratio over 5, sensitivity and specificity of the test were 76.9 and 92.3%, respectively. CONCLUSION: Pleural fluid cell IFN-gamma production assay may be useful for the diagnosis of tuberculous pleurisy.

PURPOSE: This research used mathematical modeling to project the supply and demand of emergency physicians over the next decade in Korea. METHODS: A model was used to project the annual emergency physicians (EP) workforce supply and demand through the year 2015. The mathematical equations used were as follows: Supply = number of emergency physicians at the beginning of the year plus annual residency graduates minus annual attrition; Demand formula I = 5.29 fulltime equivalent positions/emergency department (ED) x the number of hospital EDs, Demand formula II = annual ED visits/(4,700visits/EP/year), Demand formula III = (11 to 16 EP per major referral ED) + (6 to 8 EP per urban district/ regional hospital ED). RESULTS: While the most conservative demand projection was 1,505 EPs in the year 2015, the most aggressive supply estimate with a yearly supply of 120 new EPs and a 1% attrition rate was 1,362 EPs in that year. CONCLUSIONS: In Korea, emergency physicians will remain in short supply for the next ten years, even at the present levels of EM residency output.

BACKGROUND: Defects in apoptotic signaling pathways play important role in tumor initiation, progression, metastasis and resistance to treatment. Several proteins which may promote tumorigenesis by inhibiting apoptosis were identified. The survivin protein is the member of inhibitor of apoptosis protein(IAPs) family which inhibits apoptosis. Unlike other IAPs, it is expressed in during the fetal period but not in adult differentiated tissues. Many reports have stated that survivin is selectively expressed in many cancer cell lines and cancer tissues. We performed immunohistochemical analysis for survivin expression in non-small cell lung cancer to get evaluate its clinical implication. METHODS: Twenty nine surgically resected lung cancers were examined. Immunohistochemical staining were performed by immuno-peroxidase technique using avidin-biotinylated horseradish peroxidase complex in the formalin-fixed, paraffin-embedded tissue 4 µm section. Anti-survivin polyclonal antibody was used for primary antibody and anti-p53 monoclonal antibody was also used to analyze the correlation between survivin and p53 expression. The survivin expression scores were determined by as the sum of the stained area and intensity. RESULTS: Immunohistochemical analysis showed cancer specific expression of survivin in 20 of 29 cases (69.0%). Western blot analysis also showed the selective survivin expression in turmor tissue. There was no correlation between survivin expression and clinicopathological parameters and prognosis. We analyzed the correlated between survivin expression and p53 expression, but found none. CONCLUSION: We confirmed the tumor specific expression of survivin in non-small cell lung cancer But this pression was not correlated with clinical parameters as well as histlogy, tumor stage recurrence, and sur rate. Also it ws not statistically correlated with the expression of p53.

PURPOSE: We attempted to determine the frequency of the type of anterior diaphragm and diaphragmatic abnormalities, and to ascertain whether these two may be correlated with respiration and patient's age. MATERIALS AND METHODS: Two hundred abdominal CT scans that were obtained at end expiration and 150 chest CT scans that were obtained at end inspiration were retrospectively reviewed for the evaluation of anterior diaphragmatic appearance, diaphragmatic defect, pseudotumor, and undulation. We evaluated the frequency of these findings and the differences of diaphragmatic appearance between the group above 60 years and the group under 59 years. RESULTS: The most common type of anterior diaphragm was lower(50.0%) on chest CT scans and superior (32.5%) on abdominal CT scans;thus, a significant relationship with respiration was observed. Diaphragmatic defect, pseudotumor, and undulation were found in 15.1%, 16.0%, 22.6% of all 350 patients, respectively. Diaphragmatic defect did not change significantly with the respiration or the type of anterior diaphragm. Pseudotumor and undulation, which were more common on chest CT scans and the lower type of anterior diaphragm, demonstrated a trend to change with respiration. Diaphragmatic defect, pseudotumor, and undulation were more common in older age above 60 years(26.4%, 23.6%, 36.8%, respectively) than in under 59 years(7.3%, 10.7%, 12.6%, respectively). CONCLUSION: Anterior diaphragmatic appearances may not be constant but may change with respiration. Respiration and aging process may be the main causes of diaphragmatic abnormalities.

BACKGROUND: Stereotactic thalamotomy and pallidotomy for Parkinson's disease or essential tremor have been performed under local anesthesia. But some neurosurgeons have been reluctant to utilize this technique because of patient discomfort and neurological complications. So we used the propofol that provides excellent sedation and rapid and smooth recovery of mental abilities with minimal side effects. METHODS: After the patients were placed into the Leksell's stereotactic frame, anesthesia was induced by continuous infusion of propofol at the rate of 150 mcg/kg/min and then maintained at the rate of 50 mcg/kg/min. We investigated the hemodynamic changes, ABGA, total dose of propofol, time to loss of consciousness, recovery time from the end of infusion to eyes opening and side effects. RESULTS: The blood pressure decreased significantly at infusion start 15 min and 30 min (p<0.05) and heart rate decreased significantly at infusion start 30 min (p<0.05). The PaCO2 increased significantly at infusion start 15 min and 30 min (p<0.05). Total dose of propofol was 202.4+/-59.8 mg, time to loss of consciousness was 13.0+/-4.4 min, recovery time was 9.0+/-4.7 min and side effects were pain on infusion (2 cases) and postoperative nausea (1 case). CONCLUSIONS: Stereotactic thalamotomy and pallidotomy for Parkinson's disease or essential tremor were performed by infusion of propofol with minimal side effects and no neurological complications.

BACKGROUND: Artificial insemination by donor (AID) is important to chance the pregnancy in male infertile couples by requiring appropriate medical, legal and ethical reviews. The purpose of this study was to investigate the perception changes of AID to collect the basic information for establishing the sperm donation, cryopreservation and artificial insemination management system. METHODS: We evaluated the people's thought of sperm donation, cryopreservation, and artificial insemination by donor by means of national inquiry survey from 247 infertile couples for 4 weeks from October 2016. The questionnaires were composed of 4 areas, and each questionnaire consisted of 15 items. Changes in the perception of AID by year were investigated after review of domestic journals. RESULTS: 67.6% of respondents knew the growth of couples with difficulty getting pregnant due to male infertility. 82.2% of respondents replied the necessary of sperm bank as a treatment option for infertility and 40.5% knew the donation and receipt system of sperm. In the survey of change perception of AID according to year, 37.5% and 39.5% of respondents were got information about AID from doctor in 2003 and 2004, but 49.6% from broadcasting in 2016. As a child grows up, 4.0% (2003), 9.0% (2014), and 42.8% (2016) of respondents answered to tell the child about AID. CONCLUSIONS: Infertile couple's thought of AID about the extension of opportunities for male infertility treatment is changed. In conclusion, it is necessary to establish institutional system of sperm donation, cryopreservation and artificial insemination prior to public sperm bank operation.

BACKGROUND: We assessed the frequency and types of ankle fractures that frequently occur during parachute landings of special operation unit personnel and analyzed the causes. METHODS: Fifty-six members of the special force brigade of the military who had sustained ankle fractures during parachute landings between January 2005 and April 2010 were retrospectively analyzed. The injury sites and fracture sites were identified and the fracture types were categorized by the Lauge-Hansen and Weber classifications. Follow-up surveys were performed with respect to the American Orthopedic Foot and Ankle Society ankle-hindfoot score, patient satisfaction, and return to preinjury activity. RESULTS: The patients were all males with a mean age of 23.6 years. There were 28 right and 28 left ankle fractures. Twenty-two patients had simple fractures and 34 patients had comminuted fractures. The average number of injury and fractures sites per person was 2.07 (116 injuries including a syndesmosis injury and a deltoid injury) and 1.75 (98 fracture sites), respectively. Twenty-three cases (41.07%) were accompanied by posterior malleolar fractures. Fifty-five patients underwent surgery; of these, 30 had plate internal fixations. Weber type A, B, and C fractures were found in 4, 38, and 14 cases, respectively. Based on the Lauge-Hansen classification, supination-external rotation injuries were found in 20 cases, supination-adduction injuries in 22 cases, pronation-external rotation injuries in 11 cases, tibiofibular fractures in 2 cases, and simple medial malleolar fractures in 2 cases. The mean follow-up period was 23.8 months, and the average follow-up American Orthopedic Foot and Ankle Society ankle-hindfoot score was 85.42. Forty-five patients (80.36%) reported excellent or good satisfaction with the outcome. CONCLUSIONS: Posterior malleolar fractures occurred in 41.07% of ankle fractures sustained in parachute landings. Because most of the ankle fractures in parachute injuries were compound fractures, most cases had to undergo surgical repairs.
