Aspiration can generate postoperative pulmonary morbidity of varing severity, depending on the type and volume of the aspirate. Epidural anesthesia can lead to local anesthetic systemic toxicity with mental change, followed by respiratory depression and abdominal and intercostal muscle weakness depressing the ability of the patient to cough and clear the airway. The authors experienced a case of pulmonary aspiration with systemic toxicity after epidural anesthesia for cesarean section. The chest X-ray showed alveolar consolidation at left lower lung field and arterial blood gases showed that PaO2 decreased. The exact causes of mental change and respiratory depression were unknown, but we suspected it lidocaine induced systemic toxicity due to vascular absorption, When airway reflexes are ineffective during face mask ventilation of the lungs, aspiration of clear oral secretions can generate small airway obstruction.

PURPOSE: Predicting life expectancy of terminally ill cancer patients is very important. In many studies, ferritin is detected at higher levels in the sera of cancer patients, and higher ferritin level correlates with aggressiveness of disease and poor outcomes of patients. This study evaluated a prognostic role of serum ferritin levels in terminally ill cancer patients. METHODS: This study enrolled 65 terminally ill cancer patients from March through June 2012. We assessed routine laboratory findings including serum ferritin levels as well as demographic and clinical characteristics of the patients. To examine the association between serum ferritin levels and patient's characteristics, we used Spearman's correlation analysis, Wilcoxon's rank sum test or Kruskal-Wallis test, as appropriately. For multivariate analysis, Cox's proportional hazard regression model was used to evaluate significance of serum ferritin levels as a prognostic factor. RESULTS: A negative correlation between serum ferritin levels and survival time was found. After adjusting for sex, age, performance status, creatinine levels and white blood cell counts, serum ferritin levels were significantly associated with survival time. CONCLUSION: Even at the very end of life of terminal cancer patients, serum ferritin levels were an independent prognostic factor for survival.

Polyomavirus disease is a re-emerging infectious complication in renal transplantation. It manifests as symptomless renal dysfunction and progresses to graft loss unless the prompt diagnosis and intervention are initiated. A gold standard for diagnosis is the renal biopsy. Recently, the molecular diagnosis can be made using plasma PCR technique before histologic confirmation. Reduction of immunosuppression is a mainstay of treatment. Leflunomide and other antiviral agents could be used successfully in selected cases. The screening using urine decoy cell and subsequent plasma PCR may detect the BK viral replication, and preemptive intervention will prevent development of overt nephropathy without risk of rejection. This review will cover the recent advances and clinical issues in diagnosis and management of polyomavirus disease, mainly BK virus associated nephropathy.

Purpose:
To identify the incidence and characteristics of immediate substitutions of injured players that occurred during Korean professional football league matches.
Methods:
This study included injuries that resulted in immediate substitutions of injured players during Korean professional football league matches. The match broadcasting records were used to check the date of the match, home-away matches, the team to which players belong, the position on the field of play, and the time of injury.The match recording videos were used to evaluate the injury mechanism and the injured area.
Results:
In 228 matches, 66 immediate substitutions of injured players occurred, with an incidence rate of 0.3 per match. Total number of substitutions due to injuries most frequently occurred in May, with 15 substitutions in 30 matches; however, after considering the number of substitutions per match in each month, November was the most severe month with 0.53 substitutions after injuries per match. Most frequently injured players were defenders (36.4%), followed by midfielders, forwards, and goalkeepers. Immediate substitutions of injured players took place 32 times in the first half and 34 times in the second half. 51.5% of all injuries were related to collisions, and injuries to the knee and thigh accounted for 45.5% of all injuries.
Conclusion
There were 66 immediate substitutions of injured players during a single season of the Korean professional football league, with 0.3 substitutions after injuries per match. To prevent and manage serious injuries that can occur during a football match, a thorough analysis of risk factors of injuries that lead to immediate substitution is required.

Objective:
: To evaluate and compare the clinical and radiographic features of 25 patients with infectious spondylitis treated with anterior debridement and reconstruction using autogenous bone grafts vs. a metal cage with allogenic bone grafts.
Methods:
: The study analyzed 25 patients diagnosed with infectious thoracolumbar spondylitis who underwent anterior radical debridement and reconstruction. Autogenous bone grafts were used in 13 patients (group 1), and a metal cage with allogenic bone grafts was used in 12 patients (group 2). Clinical outcomes were assessed by the visual analogue scale (VAS) scores and neurological status. Additionally, the serological results and the radiographic results using the sagittal Cobb angle were compared. Fusion was evaluated by computed tomography (CT) imaging at 24 months postoperatively.
Results:
: Both groups showed a significant decrease in the postoperative mean VAS scores; however, only, group 1 patients showed a significantly higher VAS score than group 2 patients, 1 month postoperatively (p=0.002). The postoperative neurological status significantly improved. Elevated C-reactive protein levels and erythrocyte sedimentation rate values returned to normal limits at the 2-year follow-up without recurrent infection. No significant intergroup difference was observed in Cobb angle. Bony fusion was confirmed in all patients at CT 24 months postoperatively.
Conclusion
: Although the use of a metal cage with allogenic bone grafts for anterior column reconstruction remains controversial, our results suggest that it can be considered as an effective treatment of option for anterior column reconstruction in patients with infectious spondylitis.

BACKGROUND: ADPKD is one of the most common hereditary renal disease in adult and is a systemic disorder with a variety of cardiovascular manifestations. To elucidate the clinical characteristics of cerebrovascular complications in Korean ADPKD patients, we reviewed the medical records of ADPKD patients who was registered in ADPKD clinic of Seoul National University Hospital. METHODS: A total of 18 adult patients were included and their sex ratio was 8:10. The median age of ADPKD diagnosis was 45.5 year (range 19-85), and age at cerebrovascular accident(CVA) was 52 years(22-82). The median duration from hypertension to CVA was 8 years(0-30). RESULTS: There were 5 cases of infarction, 4 cases of intracerebral hemorrhage, 4 cases of subarachnoid hemorrhage, and 4 cases of transient ischemic attack. Other clinical parameters of ADPKD were not different from patients who were not complicated with CVA. Intracranial aneurysms were detected in 6 patients and their median age at diagnosis was 47.5 years(33-66). Four cases were manifested as subarachnoid hemorrhage. Five cases were diagnosed through TFCA, and two of them were revealed as multiple aneurysms. Five cases received surgical treatment and five of six cases improved without any neurologic sequeale. MR angiography(MRA) were taken in 16 asymptomatic patients, and multiple aneurysms were newly detected in one of them. CONCLUSION: Cerebrovascular complications in Korean ADPKD patients were not significantly different from western patients. Intracranial aneurysms must be included in differential diagnosis in ADPKD patients who manifest an acute neurologic symptoms, and high-risk group need to be screened selectively with MRA.

A series of 44 patients with cerebral arteriovenous malformations(AVM's) treated by various modalities from January, 1987, to March, 1994, at Chung-Ang University Hospital were reviewed with emphasis on the outcome. Of these patients, 8 received conservative treatment, 16 only surgery, 4 combined embolization and surgery, and 16 embolization alone. The follow-up period ranged from 7 months to 54 months with a mean of 20.6 months. The efficacy of the combined treatment was evaluated by the complications and the clinical outcome. When compared with surgery alone, preoperative embolization facilitated surgery by reducing intraoperative bleeding and shortening the time of surgery. Clinical outcome was better after preoperative embolization, with no occurrence of major complications and mortality. Five AVM's were totally occluded by embolization alone, but of the 5 cases, 1 case was readmitted due to bleeding 2 years after the embolization. It is concluded that combined treatment with preoperative embolization and surgery was helpful in the management of large, high grade AVM's by reducing the complications associated with their surgical removal.

Melanosis ilei is a condition that's characterized by gross greyish-black or brownish-black pigmentation of the mucosa of the terminal ileum. There were several substances that produce gastrointestinal tract pigmentation such as lipofuscin, iron sulphide (FeS), Hemosiderin and exogenous material such as silicates and titanium. We report here on a case of a 58-year-old female who ingested charcoal for a long time, and she was diagnosed with melanosis ilei by colonoscopy. Her condition improved after she stopped ingesting the charcoal.

A choledochocele is an expanded sac of the duodenal side of the distal common bile duct (CBD), and is categorized as a type III choledochal cyst. Unlike other choledochal cysts, it can be easily overlooked because of its very low prevalence, non-specific clinical symptoms, and lack of distinctive radiological findings. However, a patient having a repeated pancreaticobiliary disorder with an unknown origin, frequent abdominal pain after cholecystectomy, or repeated non-specific gastrointestinal symptoms can be suspected as having a choledochocele, and a more accurate diagnosis can be achieved via endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic ultrasound. Because it rarely becomes malignant, a choledochocele can be treated via endoscopic sphincterotomy (EST) and surgical treatment. The authors were able to diagnose choledochocele accompanied by a stone in a patient admitted to the authors' hospital due to cholangitis and pancreatitis. The patient's condition was suspected to have been caused by a distal CBD stone detected via multiple detector computed tomography and ERCP, and was successfully treated via EST.

BACKGREOUND: The aim of this study was to compare the respiratory mechanics between young and elderly during enflurane anesthesia using flow-interruption technique. METHODS: Fourteen patients were divided into 2 groups; for young aged group (Group Y)(24.9 4.9 years) and old aged group (Group O)(73.4 5.6 years). After anesthetic induction, endotracheal intubation was performed with Univent tube, and then tracheal pressure was measured at the distal end of the tube. 1.5 vol% of enflurane and 0.15 mg/kg of vecuronium were administered to maintain anesthesia. IMV (intermittent mandatory ventilation) was applied with Siemens Servo 900C ventilator and anesthetic gases were supplied via low pressure inlet of the ventilator. Tidal volume (10 ml/kg) was fixed during measurements for each patient. After stabilization of vital signs, respiratory parameters were measured before surgery. End-inspiratory occlusion was applied at least 3 seconds. Pressure, flow and volume were monitored and recorded with Bicore CP100 pulmonary monitor. The data were transfered to a PC and analyzed by a processing software. Total respiratory (Rrs), airway (Raw) and tissue (Rve) resistances, and dynamic (Cdyn) and static (Csta) compliances were calculated. Mann-Whitney U test was used for statistical analysis. RESULTS: There were no statistically significant differences for the Cdyn and Csta values between the two groups. But the values of Rrs, Raw and Rve were higher in the Group O than the Group Y. CONCLUSION: During enflurane anesthesia, the values of Rrs, Raw and Rve were higher in the Group O than the Group Y. To elucidate the exact causes of the above results, further studies are needed.
