OBJECTIVE: So called "minimally invasive procedures" have evolved from chemonucleolysis, automated percutaneous discectomy, arthroscopic microdiscectomy that are mainly working within the confines of intradiscal space to transforaminal endoscopic technique to remove herniated epidural disc materials directly. The purpose of this study is to assess the result of endoscopic spinal surgery and favorable indications in the thoracolumbar spine. METHODS: The records of 71 patients, 73 endoscopic procedures, were retrospectively analysed. Yeung Endoscopic Spine Surgery system with 7 mm working sleeve and 25degrees viewing angle was used. The mean follow up period was 6 months (range,3-9). RESULTS: Operated levels were from T12-L1 disc down to L5-L6 or S1 disc. Of 71 cases, 2 patients underwent transforaminal endoscopic surgery twice due to recurrence after initial operation. MacNab's criteria was used to assess the outcome. Favorable outcome, excellent or good, was seen in 78% (57 procedures) of the patients. Among 11 fair outcomes, only 1 procedure was followed by secondary open procedure, laminectomy with discectomy. Two of 5 poor outcomes were operated again by same procedure which resulted in fair outcomes. One patient with aggravated cauda equina syndrome remained poor and a lumbar fusion procedure was performed in other patient with poor outcome. There were 2 postoperative discitis that were treated with conservative care in one and anterior lumbar interbody fusion in the other. CONCLUSION: Evolving technology of mechanical, visual instrument enables minimal invasive procedure possible and effective. The transforaminal endoscopic spinal surgery can reach as high as T12-L1 disc level. The rate of favorable outcome is mid-range among reported endoscopic lumbar surgery series. Authors believe that the outcome will be better as cases accumulate and will be able to reach the rate of standard open microsurgery.

Cranioplasty has long been performed by many physicians with different materials from the prehistoric era. Among the materials, methyl methacrylate has been known to be the superior to any other substitutes since 1940s in biologic, chemical and physical characteristics and its availability. So the authors review 72 patients who underwent cranioplasty with methyl methacrylate at out hospital from 1985 to 1989. The clinical analyses were as follow : 1) There was male predominance and epidural hematomas, compound, comminuted depressed fractures by traffic accidents or fall down injuries were the main causes of craniectomy. 2) The location of defects was mainly frontal and/or parietal area and average size of defects was 17cm2 in plain skull film measurements. 3) The cosmetic results were satisfactory. 4) Complication rate was 6% and there was no mortality.

PURPOSE: We use many electronic devices for treating patients in our emergency department. Several studies have reported an association between electromagnetic field exposure and risk of cancer and other diseases. Our purpose was to measure the intensity of power-frequency magnetic fields in the emergency department and evaluate the conditions exceeded regulation guidelines for power-frequency magnetic fields. METHODS: Extremely low frequency magnetic fields were measured at 78 ordinary working spots in our tertiary hospital's emergency department (ED) and evaluated according to national regulatory guidelines and SWEDAC. Each spot was measured four times. During measurement, every electrical device in the emergency department was turned on. RESULTS: The average intensity of the magnetic fields in our emergency department was 0.99+/-1.27 mG. The maximum intensity was 8.3 mG, which was found in the pediatric section. CONCLUSION: The power-frequency magnetic field intensities of the various sections of our ED did not exceed national regulatory guidelines. However, pediatric and the minor emergency section showed magnetic fields intensities far above 2 mG. We found these high values outside the pediatric and waiting sections, where the electrical cabinet panel was located. We conclude that the electrical cabinet panel should be shielded and that similar studies are needed for other emergency departments.

PURPOSE: To evaluate the questions of hand and wrist section of Korean orthopedic in-training examination (KOITE). METHODS: We analyzed questions of hand and wrist section of KOITE between 2010 and 2014. The weight of hand and wrist section was calculated and topics were thoroughly analyzed. The construct of questions were evaluated and taxonomic classifications were also performed. The frequency of presentations of physical examinations and radiologic evaluations in diagnosis and treatment related questions were analyzed. The coverage of available references which were recommended by Korean Orthopedic Association (KOA) were analyzed. RESULTS: Sixty one out of 500 questions (weight: 12.2%) were related with hand and wrist section. Disease (30/61, 48.2%) was more commonly asked than trauma, however most frequently asked topic with a broad classification was fractures and dislocations (19/61, 31.1%). The description only questions (46/61, 75.4%) were most commonly asked construct of question. According to taxonomic classification, taxonomy B (diagnosis; 27/61, 44.3%) was most frequently asked. The Campbell's operative orthopedics (54/61, 88.5%) and textbook of KOA (53/61, 86.9%) were representative references covering questions most widely. CONCLUSION: This analysis of hand and wrist section of KOITE could be used as the check-up tools for resident training programs of each training hospitals.

Intravenous leiomyomatosis is a rare benign smooth muscle tumor arising from uterine muscle or vascular wall. The disease grows into pelvic venous channel, and can extend to inferior vena cava, and, in exceptional cases, right side of the heart. A case of intravenous leiomyomatosis is presented with a brief review of literatures. A 42-year-old woman presented with one month history of vague right lower quadrant pain and leg swelling. Six years before admission, she had undergone total abdominal hysterectomy for leiomyoma of the uterus and excision of recurred mass and right salpingo-oophorectomy 32 months ago. During the follow-up, right adnexa mass was detected and the size grew progressively, so transferred to our hospital. CT scan and venograpy revealed out the large pelvic cavity mass and intravenous extension to right common iliac vein, bifurcation of IVC. Preoperative tumor embolization followed by resection of recurred pelvic tumor, removal of intravenous tumor via internal iliac vein venotomy and left salpingo-oophorectomy were done. After the operation, the symptoms were relieved and the patient resumed her normal activity.

Vagal nerve activity has been known to play a crucial role in the induction and maintenance of atrial fibrillation (AF). However, it is unclear how the distribution and concentration of local acetylcholine (ACh) promotes AF. In this study, we investigated the effect of the spatial distribution and concentration of ACh on fibrillation patterns in an in silico human atrial model. A human atrial action potential model with an ACh-dependent K+ current (I(KAch)) was used to examine the effect of vagal activation. A simulation of cardiac wave dynamics was performed in a realistic 3D model of the atrium. A model of the ganglionated plexus (GP) and nerve was developed based on the "octopus hypothesis". The pattern of cardiac wave dynamics was examined by applying vagal activation to the GP areas or randomly. AF inducibility in the octopus hypothesis-based GP and nerve model was tested. The effect of the ACh concentration level was also examined. In the single cell simulation, an increase in the ACh concentration shortened APD90 and increased the maximal slope of the restitution curve. In the 3D simulation, a random distribution of vagal activation promoted wavebreaks while ACh secretion limited to the GP areas did not induce a noticeable change in wave dynamics. The octopus hypothesis-based model of the GP and nerve exhibited AF inducibility at higher ACh concentrations. In conclusion, a 3D in silico model of the GP and parasympathetic nerve based on the octopus model exhibited higher AF inducibility with higher ACh concentrations.

In generalized amyloidosis, involvement of heart is not rare, but development fo severe conduction distubance in cardiac amyloidosis is a rare presentation in a clinical situation. We report the first case in Korea of cardiac amyloidosis with complete atrioventricular block, which was confirmed by endomyocardial biopsy. A 59-year-old woman was admitted due to drowsy mentality. We observed a severe atrioventricular conduction disturbance on the electrocardiogram and a marked hypertrophied ventricular wall and a granular sparkling appearance within the wall, a characteristic feature in cardiac infiltration of amyloidosis, on the echocardiography. Endomyocardial biopsy was performed and revealed extensive deposition of amorphous eosinophilic materials within the cardiac muscle cells. Polarizing illumination after Congo-red staining showed typical green birefrigence. We performed a insertion of permanent pacemaker(VVI type) for the treatment of complete atrioventricular block.

BACKGROUND AND OBJECTIVES: To investigate age-specific and sex-specific distributions of blood cholesterol in the general Korean population. SUBJECTS AND METHODS: We analyzed data for 8284 men and 9246 women aged > or =10 years who participated in the fifth (2010-2012) Korea National Health and Nutrition Examination Survey. Age-specific means, medians, and selected percentiles were calculated for men, premenopausal women, and postmenopausal women. RESULTS: Median total cholesterol (TC) level increased with age across all age groups, from 147 to 196 mg/dL in males and from 159 to 210 mg/dL in females. Triglyceride (TG) levels increased with age in females; however, in males, TG levels rapidly increased during young adulthood, peaked at 50-54 years, and then decreased. High density lipoprotein-cholesterol (HDL-C) levels were higher in females than in males and decreased with increasing age in both males and females. Low density lipoprotein-cholesterol (LDL-C) levels increased with age across all age groups, from 89 to 127 mg/dL in males and from 82 to 113 mg/dL in females. Lipoprotein-cholesterol fraction (TC/HDL-C, LDL-C/HDL-C, TG/HDL-C, non-HDL-C) levels increased with age in females, but increased more rapidly in males during young adulthood and decreased after middle age. CONCLUSION: Blood cholesterol levels and lipoprotein-cholesterol fractions present different distributions by age, sex, and menopausal status.

Streptococcus salivarius meningitis is very uncommon, and most cases are iatrogenic, occurring after invasive procedures such as spinal anesthesia or lumbar puncture etc.. Post-traumatic occurrence of this infection is especially rare. A 20-year-old man with a previous history of skull base fracture was seen at the emergency department with signs of acute bacterial meningitis. The CSF had a few gram positive cocci with neutrophilic pleocytosis, which were identified as S. salivarius by the Vitek system (bioMerioux, Inc., Hazelwood, MO, USA), rapid ID 32 Strep (bioMerieux, Marcy-l'Etoile, France) and 16S rRNA sequencing. The microorganism showed intermediate resistance to penicillin (MIC=0.25 microg/mL) but was susceptible to cefotaxime (MIC=0.25 microg/mL) and vancomycin (MIC= 0.75 microg/mL). The patient was treated with ceftriaxone and vancomycin. He also had his CSF leakage repaired by an endoscopic approach. To our knowledge, this is the first case of S. salivarius meningitis reported in Korea.
