OBJECTIVE: While the optic nerve sheath diameter (ONSD) is measured by computed tomography and ultrasonography as an indicator of an elevation in the intracranial pressure (ICP), it is unclear which ONSD measurement is useful for predicting an increased ICP. This study examined the comparability between the ONSD measured by computed tomography and ultrasonography. METHODS: A prospective study of 150 patients in the emergency center was performed. The ONSD was measured 3 mm behind the globe of all patients by computed tomography and ultrasonography. The receiver operator characteristic (ROC) curve was analyzed to determine the diagnostic utility of detecting ICP through ONSD. RESULTS: A total of 150 patients were enrolled. Thirty-three patients (22.0%) were found to have an increased ICP. The ONSD in patients with increased ICP was significantly higher than that of normal ICP patients measured by computed tomography and ultrasonography. Moreover, computed tomography and ultrasonography revealed an area under the ROC curve value of 0.886 and 0.933, respectively. The ONSD measurement by computed tomography and ultrasonography produced similar results (P=0.256). CONCLUSION: The ONSD measured by computed tomography and ultrasonography is a valuable indicator of an ICP elevation. Therefore, either of the two diagnostic methods for monitoring the ICP can be used in patients with a critical care and resource-limited setup.

Sodium glucose cotransporter 2 (SGLT2) inhibitor has been recently reported of diabetic ketoacidosis due to accumulation of ketone bodies in patients with severe dehydration caused from such like diarrhea even though the patient had normal glucose level. This is a case of ketoacidosis in normal glucose level as production of ketone bodies is stimulated in liver with increased secretion of glucagon by stimulation of α cells in pancreas due to increase of lipolysis caused from reducing insulin and by SGLT2 inhibitor among patients who are under concurrent insulin and SGLT2 inhibitor. Thus, insulin dosage reduction requires caution in order to control blood glucose level on combined treatment of SGLT2 inhibitor in a patient who is administering insulin because the patient may be caused ketoacidosis in normal blood glucose level.

A pulmonary mucinous cystadenocarcinoma is an extremely rare tumor that is considered to be a cystic variant of mucin-producing lung adenocarcinoma. We present a case of pulmonary mucinous cystadenocarcinoma in a 54-year-old woman. Chest CT scans showed a 4.3-cm-sized, lobulated, well-defined, and homogeneous mass in the right middle lobe with peripheral stippled calcifications that demonstrated low-attenuation with no enhancement after contrast administration; 18F-fluorodeoxyglucose (FDG) PET/CT demonstrated mild heterogeneous FDG uptake. The mass was diagnosed as adenocarcinoma with mucin production by transbronchial lung biopsy. Right middle lobectomy was performed, and the pathologic examination disclosed a pulmonary mucinous cystadenocarcinoma.

There is increasing attention to medical problems of musicians. Many studies find a high prevalence of work-related musculoskeletal disorders in musicians, ranging from 73.4% to 87.7%, and string players have the highest prevalence of musculoskeletal problems. This paper examines the various positions and movements of the upper extremities in string players: 1) basic postures for holding instruments, 2) movements of left upper extremity: fingering, forearm posture, high position and vibrato, 3) movements of right upper extremity: bowing, bow angles, pizzicato and other bowing techniques. These isotonic and isometric movements can lead to musculoskeletal problems in musicians. We reviewed orthopedic disorders that are specific to string players: overuse syndrome, muscle-tendon syndrome, focal dystonia, hypermobility syndrome, and compressive neuropathy. Symptoms, interrelationships with musical performances, diagnosis and treatment of these problems were then discussed.

Lack of hygiene and puerperal mastitis are common causes of bacterial diseases in nursing neonates. The aim of this study was to isolate microorganisms from milk samples of healthy female Jindo dogs with suckling puppies and to investigate antimicrobial susceptibility against the isolated bacteria. Milk samples were collected from 120 udders of 12 lactating Jindo dogs that were 2~4 years old without any clinical diseases including mastitis. Bacteria were isolated from 64 milk samples (53.3%), either singly (76.6%) or in combination (23.4%). Staphylococcus (S.) spp. was the most common microorganisms (74.7%) isolated from canine milk, followed by Haemophillus spp. (10.9%), Streptococcus spp. (9.6%), Gardnerella spp. (2.4%) and Moraxella spp. (2.4%). The most frequently isolated organism was S. warneri (31.3%). Antimicrobial susceptibility of these bacteria was tested with 17 antimicrobial agents by Kirbyand Bauer standardized disc diffusion method. Results indicated that bacteria isolated from healthy canine milk were mostly susceptible to amoxicillin-clavulanic acid, cephalothin and ceftiofur, but were resistant to erythromycin, neomycin and tetracycline.

PURPOSE: We evaluated the clinical outcomes of the autologous platelet rich plasma injection for the treatment of recalcitrant medial and lateral epicondylitis. MATERIALS AND METHODS: Nineteen cases with recalcitrant medial and lateral epicondylitis despite of conservative treatment for 1 year were enrolled in this study. Each patient underwent autologous platelet rich plasma injection and followed up minimally of 40 weeks. The assessment included a preoperative and postoperative Visual Analogue Scale (VAS) (0~10) at 4, 8, 12, 24 and 36 weeks and overall satisfaction was evaluated with Roles & Maudsley score at 36 weeks after injection. We also compared the clinical outcomes between medial and lateral epicondylitis group. RESULTS: Mean preoperative VAS was 8.7 points and improved to 5.1, 5.2 and 4.7 at 12, 24 and 36 weeks follow up, respectively. Roles & Maudsley score was excellent in 5 cases(26%), good in 7 cases(37%), acceptable in 4 cases(21%) and poor in 3 cases(16%). On the comparison of medial and lateral epicondylitis group, there was no statistical significant difference (p=0.38). CONCLUSION: The autologous platelet rich plasma injection for recalcitrant medial & lateral epicondylitis is thought to be a alternative treatment option.

BACKGROUND/AIMS: The most common type of syncope in young adults is neurocardiogenic in origin, which is not related to organic problems and has a benign nature. Therefore, there have been few reports regarding syncope in young Korean adults. Here, we examined the causes of syncope and its clinical characteristics in young combat and auxiliary police in Korea. METHODS: We performed a retrospective study of the medical records of 193 combat and auxiliary police in Korea admitted to the National Police Hospital for syncope or presyncope between January 2004 and December 2007. RESULTS: The subjects' mean age was 21+/-1.2 years, and there were 2.8+/-2.9 episodes of syncope (mean+/-SEM). The first syncope occurred after enlistment in the police in 102 patients (52.8%). Basic diagnostic studies showed two cases of elevated creatine phosphokinase and one case of anemia to be related to syncope. Syncope-related traumatic injuries occurred in 38 patients (19.7%), and syncope was more prevalent in the summer. Head-up tilt test was performed in 175 of the 193 patients, and 123 showed a positive response. Other evaluations, including brain magnetic resonance imaging, electroencephalography, and echocardiography, were not helpful for diagnosis. Syncope was neurocardiogenic in origin in the majority of cases. Other causes of syncope were exhaustion (n=2), hyperventilation syndrome (n=2), Meniere's disease (n=1), anemia (n=1), and psychiatric problems (n=5). The causes of syncope could not be identified in 59 patients (30.5%). CONCLUSIONS: Neurocardiogenic syncope was the most common type in our study population. More than half of our patients experienced their first episode after enlisting with the police. Further studies in these groups are necessary.

OBJECTIVE: To assess the feasibility, safety, and effectiveness of the balloon-assisted technique with HyperForm balloon in the endovascular treatment of wide-necked intracranial aneurysms. METHODS: A total of 34 patients with 34 wide-necked intracranial aneurysms were treated with endovascular coil embolization using balloon-assisted technique with Hyperform balloon. Twenty-nine aneurysms (85.3%) were located in the anterior circulation. The group of patients was comprised of 16 men and 18 women, aged 33 to 72 years (mean : 60.6 years). The size of aneurysms was in the range of 2.0 to 22.0 mm (mean 5.5 mm) and one of neck was 2.0 to 11.9 mm (mean 3.8 mm). The dome to neck ratio was ranged from 0.83 to 1.43 (1.15). Sixteen patients were treated for unruptured aneurysms and the remaining 18 presented with a subarachnoid hemorrhage. RESULTS: In the 34 aneurysms treated by the remodeling technique with HyperForm balloon, immediate angiographic results consisted of total occlusion in 31 cases (91.2%) and partial occlusion in three cases (8.8%). There were five procedure-related complications (14.7%), including two coil protrusions and three thromboembolisms; Except one patient, all were successfully resolved without permanent neurologic deficit. No new bleeding occurred during the follow-up. Twenty patients (59%) underwent angiographic follow-up from 2 to 33 months (mean 9.2 months) after treatment. Focal recanalization with coil compaction of the neck portion was observed in 5 cases (25%). Only one case showed major recanalization and underwent stent-assisted coil embolization. CONCLUSION: The balloon-assisted technique with Hyperform balloon is a feasible, safe, and effective endovascular treatment of wide-necked cerebral aneurysms.

BACKGROUND: In Korea, cases with hepatitis A have been reported to Korea Centers for Disease Control and Prevention through the sentinel surveillance system. However, it was difficult to study the exact nation-wide incidence of hepatitis A infection. We studied the incidence of clinically apparent hepatitis A infection and the seroprevalence of anti-HAV IgG among auxiliary police officers. MATERIALS AND METHODS: We analyzed clinically apparent and hospitalized hepatitis A patients from 2002 to 2006 in National Police Hospital via medical records. We also measured anti-HAV IgG antibody from 507 auxiliary police officers. RESULTS: The estimated annual incidence of clinically apparent hepatitis A infection among auxiliary police officers was 10.6-14.8 cases per 100,000 population from 2002 to 2006. The overall anti-HAV IgG seropositive rate among auxiliary police officers was 0.6% (3/507). CONCLUSION: Among auxiliary police officers, the estimated annual incidence of clinically apparent hepatitis A infection was above 10 cases per 100,000 population and the positive rate of anti-HAV IgG was very low. The results were comparable to those in the low endemicity countries. The routine HAV vaccination among auxiliary police officers might be suggested.
