BACKGROUND: Liver transplantation (LT) is a complicated procedure with a high incidence of postoperative acute kidney injury (AKI). Previous studies indicate that even transient or mild post-LT AKI can result in critical conditions, including prolonged stays in hospitals and intensive care units and increased morbidity and mortality. The aim of this study was to investigate the association between body mass index (BMI) and occurrence of AKI in LT recipients. METHODS: Medical data from 203 patients who received LT surgery from January 2010 to August 2016 in a single university hospital setting were retrospectively collected and analyzed. Patients were classified as either underweight (BMI <20 kg/m²) or normal weight (20 ≤ BMI < 30 kg/m²). Demographic data, anesthetic methods, complications, and perioperative laboratory test values of each patient were assessed. Propensity analyses and logistic regression were performed to evaluate the association between BMI and post-LT AKI. RESULTS: There was no significant difference in occurrence of post-LT AKI between underweight and normal weight patients. The underweight patient group had significantly longer hospital stay compared with the normal weight patient group (P = 0.023). CONCLUSIONS: BMI classification was neither a positive nor negative predictor of postoperative AKI occurrence. However, patients with lower BMI had significantly longer hospital stay compared with their counterparts. Although our study was limited by its retrospective design, our observations suggest that lower BMI might play a role in post-LT AKI.

A 38-year-old female patient had bradycardia in the preoperative electrocardiogram (ECG), and she showed severe bradycardia, with the heart rate (HR) under 40 beats per minute (bpm) even after arrival in the operating room. Immediately after endotracheal intubation, ventricular tachycardia with HR over 200 bpm occurred, but it disappeared voluntarily. The surgery was postponed for additional cardiac evaluation because of the persistent severe bradycardia. On postanesthesia day 2, complete atrioventricular (AV) block appeared. We expected spontaneous recovery over 2 weeks, but the complete AV block persisted. A permanent pacemaker was eventually inserted, and the patient was discharged without other complications on day 4 after insertion of the pacemaker. We report this case because complete AV block has commonly occurred in patients with risk factors such as first AV block, secondary AV block, or bundle branch block, but complete AV block has occurred despite the absence of arrhythmia in this patient.

A 43-year-old woman was admitted due to fever, chills, and headache for several days and was diagnosed as infective endocarditis. Intraoperative transesophageal echocardiography (TEE) examination confirmed severe aortic stenosis and showed relatively fresh 1.5 cm vegetation on the left coronary cusp of the aortic valve (AV) with frequent diastolic prolapse into the aortic root. This mobile vegetation partially occluded left coronary ostium, but it did not cause cardiac failure. TEE showed the vegetation to be in good position across the AV. The AV replacement with removal of vegetation and mitral valvuloplasty were performed. The patient was weaned from cardiopulmonary bypass without any hemodynamic instability or changes in ST segment on electrocardiography. She was discharged on the 28th postoperative day without any complication.

Myxofibrosarcoma is also known as a myxoid variant of malignant fibrous histiocytoma, and this is one of the most common sarcomas in the extremities of elderly people; it is characterized by a high frequency of local recurrence. We herein report on a case of myxofibrosarcoma of the bladder. A 58-year-old man was referred to our hospital because of microscopic hematuria. Computed tomography(CT) and intravenous pyelography(IVP) showed a 12x7cm sized bladder mass in the pelvic cavity. The cystoscopic finding shows a protruding mass at the dome and posterior wall of the bladder. After exploratory laparotomy and tissue frozen biopsy were done, radical cystectomy and uretero-ileo-cutaneous anastomosis were then carried out. The diagnosis of the tumor was confirmed by histopathological examination. The myxofibrosarcoma of the bladder was completely excised, and there was no evidence of recurrence after 10 months of follow-up.

PURPOSE: This study was to investigate the effects of U-Health program on metabolic syndrome of workers. METHODS: This study was conducted with a pretest-posttest control group study for 6 month from May to October 2010. Subjects in the experimental group participated in the U-Health program (n=315), whereas the control group did not (n=157). RESULTS: In the U-Health group, statistically significant reductions in BMI(body mass index), waist circumference, cholesterol, and triglyceride were observed. The results of this study showed that 6 months of U-Health program influenced on the metabolic syndrome of workers in a positive way. CONCLUSION: It is, therefore, suggested to actively utilize the U-Health program to manage the workers' health.

Intra-articular administration of local anesthetics such as bupivacaine can produce short-term postoperative analgesia in patients who are undergoing shoulder arthroscopy. Yet bupivacaine can result in cardiovascular toxicity that can lead to cardiac arrest. We experienced a case of 63-year-old male patient with severe cardiac toxicity that led to ventricular fibrillation 15 minutes after injecting 0.5% bupivacaine into the patient's shoulder joint for shoulder arthroscopy.

It is easy to overlook osteochondral lesions (OCLs) of the ankle in patients with chronic lower limb pain, such as complex regional pain syndrome (CRPS) or thromboangiitis obliterans (TAO, Buerger's disease). A 57-year-old woman diagnosed with type 1 CRPS, and a 58-year-old man, diagnosed with TAO, complained of tactile and cold allodynia in their lower legs. After neurolytic lumbar sympathethic ganglion block and titration of medications for neuropathic pain, each subject could walk without the aid of crutches. However, they both complained of constant pain on the left ankle during walking. Focal tenderness was noted; subsequent imaging studies revealed OCLs of her talus and his distal tibia, respectively. Immediately after percutaneous osteoplasties, the patients could walk without ankle pain. It is important to consider the presence of a hidden OCL in chronic pain patients that develop weight-bearing pain and complain of localized tenderness on the ankle.

The authors report a case of newly manifested severe junctional bradycardia following dexmedetomidine administration during spinal anesthesia in a polypharmacy patient. A 77-year-old woman receiving multiple medications, including a beta-blocker and a calcium channel blocker, underwent right total knee arthroplasty. After spinal anesthesia, intravenous dexmedetomidine was initiated as a sedative; her heart rate decreased, followed by junctional bradycardia (heart rate, 37–41 beats/min). Dexmedetomidine was discontinued, and a dopamine infusion was initiated. Seven hours after surgery, junctional bradycardia persisted; a temporary transvenous pacemaker was inserted, and the beta-blocker and calcium channel blocker were discontinued. The patient was discharged on postoperative day 11 without any sequelae. Anesthesiologists should be aware of dexmedetomidine’s inhibitory effects on the cardiac conduction system, especially in geriatric patients taking medications with negative chronotropic effects and in combination with neuraxial anesthesia.
