PURPOSE: The purpose of this study was to retrospectively analyze the etiologic transition of the predisposing factors and organisms for septic arthritis of the knee. MATERIALS AND METHODS: Between January 1995 and December 2006, 122 cases of septic arthritis of the knee were retrospectively evaluated for the etiologic transition and causative organism with using the patients' medical records. We researched the incidence and causative factor of septic arthritis of the knee, which was diagnosed via the patients' symptoms, physical examinations, hematologic exams, culture studies & cytology of the joint fluid. We assessed the correlation of disease with age, the year the disease happened, the causative factors and the incidence. RESULTS: Septic arthritis of the knee was increased after 40 years old, and it also increased after 1998. The most common predisposing factor was intra-articular injection of the knee joint. Even though there were no detected organisms in 79 cases (64.8%), the most common causative organism was S. aureus (20.5%). CONCLUSION: The most common etiologic factor of septic arthritis of the knee was an intra-articular injection. We should be prudent for using good aseptic technique and the correct procedure to reduce the secondary infection that's recently due to increased invasive treatment of the knee joint.

PURPOSE: To evaluate the results of surgical reconstruction of lateral capsule-ligament complex with reinforcement by periosteal flap of distal fibula and inferior extensor retinaculum for chronic lateral ankle instability. MATERIALS AND METHODS: From April 2003 to August 2006, 62 patients with chronic lateral ankle instability were operated. There were 38 males and 24 females with a mean age of 39.6 years (range, 18~61 years). Mean follow-up period was 32 months (range, 10~48 months). All patients were checked with preoperative ankle anteroposterior and lateral view, stress anterior drawer and varus test using Telos device. The clinical results were graded according to the VAS and AOFAS scale. RESULTS: VAS score improved from preoperative 8.2 points to 3.1 points. There were 38 patients who were excellent (above 90 points), 18 who were good (between 76 and 90 points), 5 who were fair (between 60 and 75 points), and 1 who was poor (below 60 points) according to the AOFAS ankle and hindfoot scale. The excellent and good results amounted to 90.3%. CONCLUSION: Surgical reconstruction of lateral capsule-ligament complex with reinforcement by periosteal flap of distal fibula and inferior extensor retinaculum is believed to be a effective method for chronic lateral ankle instability.

Granular cell tumors (GCTs) have been reported in various tissues, especially the skin and subcutaneous soft tissue of the head and neck. We report a 60-year-old man who presented with intermittent headache and dizziness for 3 months, but no other neurological symptoms. Magnetic resonance imaging (MRI) showed the presence of a mass in the pituitary stalk, and contrast-enhanced MRI showed nodular enhancement in this region. The lesion was completely excised microscopically via a frontotemporal (pterional) approach. On pathological examination, a final diagnosis of a typical GCT was made.

OBJECTIVE: Post-traumatic stress disorder (PTSD) is a group of diseases that are observed in patients who had experienced a serious trauma or accident. However, some experienced it even after only a mild traumatic brain injury (TBI), and they are easily ignored due to the relatively favorable course of mild TBI. Herein, the authors investigated the incidence of PTSD in mild TBI using brief neuropsychological screening test (PTSD checklist, PCL). METHODS: This study was conducted on patients with mild TBI (Glasgow coma scale > or =13) who were admitted from January 2012 to December 2012. As for PCL, it was done on patients who showed no difficulties in communication upon admission and agreed to participate in this study. By using sum of PCL, the patients were divided into high-risk group and low-risk group. PTSD was diagnosed as the three major symptoms of PTSD according to the Diagnostic and Statistical Manual of Mental Disorders, fourth-edifion. RESULTS: A total of 314 TBI patients were admitted and 71 of them met the criteria and were included in this study. The mean age was 52.9 years-old (range: 15-94). The mean PCL score was 28.8 (range: 17-68), and 10 patients were classified as high-risk group. During follow-up, 2 patients (2.7%) of high risk group, were confirmed as PTSD and there was no patient who was suspected of PTSD in the low-risk group (p=0.017). CONCLUSION: PTSD is observed 2.8% in mild TBI. Although PTSD after mild TBI is rare, PCL could be considered as a useful tool for screening of PTSD after mild TBI.

BACKGROUND/AIMS: Gastric cancer evolves in the pathologic mucosal milieu, and its development is characterized by both the loss of acid-secreting parietal cells and mucosal cell metaplasia, called spasmolytic polypeptide-expressing metaplasia (SPEM). Cytokines, such as interleukin (IL)-10, IL-1β, and IL-6, play a key role in gastric carcinogenesis. However, changes in the cytokine profile of SPEM have not been evaluated. METHODS: To induce SPEM in mouse stomachs, C57BL/6 mice were intraperitoneally injected with tamoxifen and sacrificed at 3, 10, and 21 days after treatment. RNA-sequencing (RNA-seq) and a multiplex bead array were used to measure cytokines in the stomachs of tamoxifen-treated/control mice. RESULTS: The administration of tamoxifen led to the rapid development and histological normalization of SPEM 3 and 10 days after administration, respectively. RNA-seq revealed that the expression of IL-10 was decreased 3 days after tamoxifen administration. The multiplex assay identified a significant decline in IL-10 levels 3 days after tamoxifen treatment (58.38±34.44 pg/mL vs 94.09±4.98 pg/mL, p=0.031), which normalized at 10 and 21 days after tamoxifen treatment. Immunofluorescence staining confirmed that IL-10 expression was markedly decreased at the time of SPEM development and subsequently returned to normal, accompanied by a reversal in histologic changes. CONCLUSIONS: IL-10 may play a pivotal role in the tamoxifen-induced acute development of gastric SPEM.

Adipose tissue is a central metabolic organ that controls energy homeostasis of the whole body. White adipose tissue (WAT) stores excess energy in the form of triglycerides, whereas brown adipose tissue (BAT) dissipates energy in the form of heat through mitochondrial uncoupling protein 1 (Ucp1). A newly identified adipose tissue called ‘beige fat’ (BAT-like) is produced through a process called WAT browning. This tissue mainly resides in WAT depots and displays intermediate characteristics of both WAT and BAT. Since the recent discovery of BAT in the human body, along with the identification of molecular targets for BAT activation, stimulating energy expenditure has been considered as a great strategy to treat human obesity and metabolic diseases. Here we summarize recent findings regarding molecular targets and thermogenic small molecules that can stimulate BAT and increase energy expenditure, with an emphasis on possible therapeutic applications in humans.

OBJECTIVE: Helicopter ambulance transport (HAT) is a highly resource-intensive facility that is a well-established part of the trauma transport system in many developed countries. Here, we review the benefit of HAT for neurosurgical patients in Korea. METHODS: This retrospective study followed neurotrauma patients who were transferred by HAT to a single emergency trauma center over a period of 2 years. The clinical benefits of HAT were measured according to the necessity of emergency surgical intervention and the differences in the time taken to transport patients by ground ambulance transport (GAT) and HAT. RESULTS: Ninety-nine patients were transferred to a single university hospital using HAT, of whom 32 were taken to the neurosurgery department. Of these 32 patients, 10 (31.3%) needed neurosurgical intervention, 14 (43.8%) needed non-neurosurgical intervention, 3 (9.4%) required both, and 11 (34.4%) did not require any intervention. The transfer time was faster using HAT than the estimated time needed for GAT, although for a relatively close distance (<50 km) without ground obstacles (mountain or sea) HAT did not improve transfer time. The cost comparison showed that HAT was more expensive than GAT (3,292,000 vs. 84,000 KRW, p<0.001). CONCLUSION: In this Korean-based study, we found that HAT has a clinical benefit for neurotrauma cases involving a transfer from a distant site or an isolated area. A more precise triage for using HAT should be considered to prevent overuse of this expensive transport method.

PURPOSE: The European Organization for Research and Treatment of Cancer (EORTC) scoring system and risk table were introduced in the 2008 European Association of Urology guidelines on TaT1 bladder cancer. We compared the recurrence and progression rate between EORTC risk tables and author's patients who underwent transurethral resection of bladder cancer (TURB) following intravesical Bacillus Calmette-Guerin (BCG) instillation. MATERIALS AND METHODS: The medical records of 251 patients who underwent TURB and were diagnosed with non-muscle-invasive bladder cancer from l993 to 2007 were analyzed. The patients were divided into 2 groups: the recurrence group and the progression group. According to the EORTC scoring system, the patients in each group were categorized in terms of number of tumors, tumor size, prior recurrence rate, T category, carcinoma in situ, and pathologic grade and the scores were summed. According to the summed scores, the recurrence group and the progression group were divided into 3 subgroups: low, intermediate, and high risk, respectively. The recurrence rate and progression rate of each group were compared with the EORTC risk tables. RESULTS: The recurrence rate and progression rate were almost similar to the EORTC risk tables. However, the recurrence rate was low in the intermediate-risk group. CONCLUSIONS: Clinical utilization of the EORTC scoring system and risk tables is very effective in predicting the recurrence and progression of non-muscle-invasive bladder cancer and in selecting treatment.
