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.

Tracheal bronchus is an uncommon anomaly in which an ectopic bronchus originates directly from the supracarinal trachea. It is usually an asymptomatic anatomical variant incidentally found on computed tomography or bronchoscopy. However, it can present with symptoms, such as chronic cough, wheezing, atelectasis, and recurrent pneumonia. We report a case of tracheal bronchus diagnosed in the neonatal period, in which the term baby presented with respiratory distress and persistent pulmonary hypertension of the newborn after birth, but no other congenital anomaly was found on further evaluation.

151 patients, with hypertensive putaminal hemorrhage, which confirmed by brain CT, were analyzed on the basis of Glasgow coma scale and Glasgow outcome scale. The results of the treatment of hypertensive putaminal hemorrhage and the assessment of the prognostic factors were as follows ; 1) The sex ratio was similar and the incidence was highest in the 5th decade for female and the 6th decade for male ; 75 percents of all cases were in the 5th and 6th decades. 2) A history of hypertension was a poor prognostic factor but a history of cerebrovascular disease was not a specific factor affecting the prognosis. 3) In the patients with low blood pressure, high G.C.S, and small amount of hematoma, were better the prognosis than in the patients with high blood pressure, low G.C.S, and large amount of hematoma. The prognosis was poor in old aged and in the patients with signs of herniation. 4) In the patients with G.C.S between 7-9, cerebral herniation signs, and the amount of hematoma between 40-80cc, the prognosis was better in operative treatment than conservative treatment. 5) The surgical modalities were not related to the prognosis.

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.

BACKGROUND: The aim of this study was to evaluate the influence of oral clonidine premedication on respiratory mechanics by tracheal intubation in smokers. METHODS: Thirty male smoker patients were randomly divided into 3 groups. For group 1 (n = 10), l microgram/kg of clonidine was premedicated. For group 2 (n = 10), 2 microgram/kg of clonidine was premedicated. Group 3 (n = 10, control group) was the no premedication group. After anesthetic induction, CMV was applied with a Siemens Servo 900C ventilator, and anesthetic gases were supplied via the low pressure inlet of the ventilator. Tidal volume (10 ml/kg) was fixed during measurements for each patient. End-inspiratory occlusion was applied for at least 3 seconds and tracheal pressure was measured at the distal end of the endotracheal tube. Pressure, flow and volume were monitored and recorded with a Bicore CP-100 pulmonary monitor. Data were measured after 2 (100% O2) and 5 (1.5 vol% enflurane with 50% N2O) minutes of tracheal intubation. Data were transferred to PC and analyzed by processing software (ANADAT). Total respiratory (Rrs), airway (Raw) and tissue (Rve) resistances, along with static (Cstat), dynamic (Cdyn) compliances were calculated. RESULTS: There were no significant differences for Rrs, Raw, Rve, Cstat and Cdyn in the three groups. CONCLUSIONS: Oral clonidine premedication in dosages up to 2 microgram/kg do not affect the changes of respiratory mechanics caused by tracheal intubation in smokers.
