OBJECTIVE: The aim of this study was to estimate the feasibility, safety and surgical outcomes of single port access laparoscopic myomectomy (SPA-M). METHODS: We reviewed the medical records of 29 patients with uterine leiomyoma who underwent SPA-M in Gumi CHA hospital between March 2010 and August 2010. We performed SPA-M with conventional rigid straight laparoscopic instruments in all cases. RESULTS: In this study, the mean of leiomyoma weight, operating time, and estimated blood loss were 55.43 gm(+/-54.79, range 5~220 gm), 69.68 min (+/-32.99, range 20~120 min.), 100 mL (+/-104.26 range minimal~300 mL), respectively. Transfusion was done in the one case. CONCLUSION: SPA-M using conventional rigid straight laparoscopic instruments was feasible and could be an alternative to conventional multi-port access laparoscopic myomectomy (MPA-M).

PURPOSE: Although chronic and recurrent rhinosinusitis is prevalent in children, little is known about its causes. Here, we investigated the humoral immunity in children with chronic or recurrent rhinosinusitis. METHODS: We examined 16 children attending the outpatient clinic at the CHA Bundang Medical Center including 11 boys and 5 girls, aged 3.11 years (mean age, 5.6 years), who had rhinosinusitis for >3 months or >3 times per year. The complete blood count with differential and total serum concentrations of Immunoglobulin (Ig) E, IgA, IgD, IgM, IgG, and IgG subclasses (IgG1, IgG2, IgG3, and IgG4) of all children were measured. All subjects received 23-polysaccharide pneumococcal vaccination (PPV), and the levels of antibodies to 5 serologic types (4, 6B, 14, 18C, and 23F) of pneumococcal capsular polysaccharide antigens were measured before and after vaccination. Post-PPV antibody titers > or =0.35 microg/mL or with a > or =4-fold increase were considered as positive responses. RESULTS: The titers of IgG, IgA, IgD, and IgM were within normal range in all 16 children, whereas the total IgE concentration was higher than normal in 2 children. IgG1 deficiency was observed in 1 patient and IgG3 deficiency in 3. After PPV, 1 patient failed to respond to all 5 serologic types, 2 failed to respond to 4 serologic types, and 2 failed to respond to 3 serologic types. CONCLUSION: Clinicians should consider the evaluation of humoral immune functions in children with chronic or recurrent rhinosinusitis who do not respond to prolonged antibiotic treatment.

BACKGROUND: Cardiac tamponade is associated with the expiratory increase and the expira-tory decrease in left ventricular filling flow. With Doppler echocardiography, we analyzed the respiratory variations of mitral and tricuspid inflows, and pulmonary and hepatic venous flows in patients with cardiac tamponade. METHODS: Respiratory hemodynamic changes in mitral and tricuspid inflows and pulmonary and hepatic venous flows were evaluated using Doppler echocardiography in 13 patients (6 men and 7 women; mean age 51+/-13 years) with large pericardial effusion and clinical cardiac tamponade, and compared the results with those of 11 control subjects (3 men and 8 women, mean age 53+/-13 years). Doppler examination was repeated after pericardiocentesis in 6 patients. RESULTS: Peak velocity of early diastolic mitral inflow (E velocity) decreased during inspiration compared with expiratory increase; the mean percentage change was 40%. Peak velocity of late diastolic mitral inflow (A velocity) decreased 13% during inspiration. E/A ratio decreased 31% during inspiration. Deceleration time (DT) and isovolumic relaxation time (IVRT) increased by 26% and 44%, respectively, during inspiration. But respiratory variations of tricuspid inflow were opposite to those of mitral inflow. Tricuspid E velocity increased during inspiration and decre-ased during expiration. The mean percentage change was 123%, which was larger than thte 40% of mitral inflow. The most characteristic findings of pulmonary venous flow during respiration were the expiratory increases of peak diastolic velocity (DV) and diastolic time-velocity integral (D-TVI). The mean percentage changes of peak systolic velocity (SV), DV and D-TVI during respiration were 27%, 45% and 53% respectively. In contrast, the SV and DV of hepatic venous flow increased during inspiration and decreased during expiration. The respiratory variations of peak systolic reverse flow velocity (SR) and peak diastolic reverse flow velocity (DR) were opposite to those of SV and DV. DR notably increased during expiration, and the mean percentage change was 61%. The ratio of RFI (Inspiratory reverse flow integral) to FFI (forward flow integral) of the tamponade group was 270%. The mean percentage changes of each parameters decreased after pericardiocentesis. CONCLUSION: Patients with cardiac tamponade showed inspiratory increases of diastolic tri-cuspid filling flow and hepatic forward flow. Expiratory increases included diastolic mitral filling flow, pulmonary venous systolic and diastolic flow, and hepatic venous reverse flow. Such res-piratory variations decreased after pericardiocentesis.

OBJECTIVES: The purpose of this study was to investigate the relationship between restricted activity due to oral diseases and oral health behaviors among adolescents. METHODS: A cross-sectional study design was used. The subjects were 238 middle school students and 231 high school students; a total of 469 students from 15 different schools located in 7 regions of Bucheon in Gyeonggi Province, Daejeon, and others. The adolescents who participated in the survey were chosen by convenience sampling. The association between restricted activities due to oral diseases and oral health behaviors was analyzed using multiple logistic regression analysis. RESULTS: The annual experience rate of oral diseases stood at 1.4 percent, while the number of days absent and early departures from school was 0.15 days per student. The rate of middle school students who were disturbed by oral disease with respect to sleep, eating, speaking, and/or schoolwork was 33.1 percent. In high school students, it was 40.6 percent. Dental pain and gingival bleeding were identified as major factors to the restriction of activities, and being disturbed while eating was related to cariogenic beverages. CONCLUSIONS: It would be of great social interest to support and promote oral health programs among adolescents. Therefore, a national survey of the status of activity restrictions due to oral diseases in adolescents should be implemented in order to make specific future plans.

Treacher Collins syndrome (TCS) is the most common and well known mandibulofacial dysostosis with characteristic clinical features including downward slanting of palpebral fissures, coloboma of the lower eyelid, hypoplastic zygomatic arches, micrognathia, macrostomia, microtia, and other deformities of the ears. TCS is caused by mutations in at least 3 genes involved in pre-rRNA transcription: TCOF1, POLR1D and POLR1C. We experienced a 1-day-old female infant with characteristic clinical features of TCS. A novel, heterozygotic mutation within the TCOF1 gene (c.3874_3875insG, p.Ala1292Glyfs*30) was identified to cause a premature stop codon.

OBJECTIVES: Remote medical services have been expanding globally, and this is expansion is steadily increasing. It has had many positive effects, including medical access convenience, timeliness of service, and cost reduction. The speed of research and development in remote medical technology has been gradually accelerating. Therefore, it is expected to expand to enable various high-tech information and communications technology (ICT)-based remote medical services. However, the current state lacks an appropriate security framework that can resolve security issues centered on the Internet of things (IoT) environment that will be utilized significantly in telemedicine. METHODS: This study developed a medical service-oriented frame work for secure remote medical services, possessing flexibility regarding new service and security elements through its service-oriented structure. First, the common architecture of remote medical services is defined. Next medical-oriented secu rity threats and requirements within the IoT environment are identified. Finally, we propose a "service-oriented security frame work for remote medical services" based on previous work and requirements for secure remote medical services in the IoT. RESULTS: The proposed framework is a secure framework based on service-oriented cases in the medical environment. A com parative analysis focusing on the security elements (confidentiality, integrity, availability, privacy) was conducted, and the analysis results demonstrate the security of the proposed framework for remote medical services with IoT. CONCLUSIONS: The proposed framework is service-oriented structure. It can support dynamic security elements in accordance with demands related to new remote medical services which will be diversely generated in the IoT environment. We anticipate that it will enable secure services to be provided that can guarantee confidentiality, integrity, and availability for all, including patients, non-patients, and medical staff.

Numerous medications have the potential to induce acute pancreatitis. However, isoniazid-induced acute pancreatitis is extremely rare. Drug-induced acute pancreatitis can be diagnosed by improvement after stopping the drug and recurrence of pancreatitis when rechallenged. We present a case of severe acute pancreatitis accompanied by multiple large pseudocysts after isoniazid treatment for pulmonary tuberculosis. We confirmed that isoniazid induced pancreatitis by rechallenging after treatment cessation. Most previous reports of isoniazid-induced pancreatitis have been clinically mild forms, and the patient fully recovered with supportive management. However, this case presents severe and permanent pancreatic damage that developed with 5 weeks of isoniazid treatment. When a patient presents with manifestations of pancreatitis during treatment of tuberculosis that includes isoniazid, the physician should consider isoniazid-induced pancreatitis.

BACKGROUND: Malignant middle cerebral artery (MCA) infarction is one of the leading cause of death for patients with acute MCA infarction. We investigated the predicting factors for developing malignant MCA infarction (MMI) using multi-parametric magnetic resonance imaging (MRI). METHODS: We included 159 MCA infarction patients who visited Dong-A University Stroke Center from January 2007 to December 2010 and were diagnosed MCA occlusion within 6 hours after symptom onset. All patients underwent brain MRI including diffusion and perfusion-weighted image. The definition of the malignant MCA infarction is as follows: 1) deterioration of neurological symptoms and consciousness with clinical signs of uncal herniation, and 2) at least two-thirds of the MCA territory with compression of ventricles or midline shifting. The neurological deterioration was observed for 7 days. The severity of neurological symptom and clinical outcome were assessed by using National Institutes of Health Stroke Scale (NIHSS) and modified Rankin Scale (mRS). RESULTS: Among 159 patients, 49 patients (30.8%) developed MMI. In a multivariate analysis, a larger diffusion volume on diffusion-weighted image, a lower regional cerebral blood volume (rCBV) ratio on perfusion-weighted image, and a higher NIHSS score on admission were identified as the predictive factors of MMI. The cut-off values of diffusion volume, NIHSS on admission and rCBV ratio were 69 mL, 15 points and 0.78. CONCLUSION: A large diffusion volume, a high NIHSS score and particularly a low rCBV ratio can predict a malignant course in MCA infarction within 6 hours of symptom onset in MCA occlusion.
