Epinephrine is frequently used to control local bleeding during surgery. However, it may be associated with complications, such as pulmonary edema, reversible cardiomyopathy, and cardiac arrest. We encountered a case of stress induced cardiomyopathy (SIC) after local epinephrine instillation. The SIC is manifested with typical left ventricular apical ballooning and clinical symptoms of a myocardial infarction without coronary stenosis. Although its prognosis is more favorable than a myocardial infarction, anesthesiologists need to be aware of the possible adverse effects of local epinephrine infiltration.

Transplant renal artery stenosis (TRAS) is a common surgical complication after kidney transplantation (KTP) and is the cause of allograft dysfunction. TRAS is a potentially curable cause of refractory hypertension and allograft dysfunction which accounts for approximately 1% to 5% of cases of post-transplant hypertension. Acute cellular rejection (ACR) is also common after KTP, which is the main cause of allograft dysfunction. Although the incidence of ACR has declined with the advent of new immunosuppressive drugs, it is still around 15% worldwide. Although each disease is frequently seen individually, seeing both together is rare. A 42-year-old man with end stage renal disease underwent KTP, and the donor was his younger brother. Four months after KTP, his serum creatinine was increased to 2.1 mg/dL, and renal biopsy showed interstitial lymphocytic infiltration and tubulitis. With the diagnosis of acute T-cell mediated rejection, steroid pulsing therapy was started, but it was resisted. Therefore thymoglobulin 60 mg (1 mg/kg/day) was administered for 6 days, but serum creatinine was 1.8 mg/dL. Abdomen magnetic resonance angiography showed TRAS, stenosis at the anastomosis site and lobar artery in the lower pole. Percutaneous transluminal angiography was performed successfully. After balloon angioplasty, the stenotic lesion showed a normal size and blood flow. The patient's renal function returned to normal levels and he is currently being followed up for 9 months.

Hyperuricemic patients with gouty arthritis or tophi, a serum uric acid concentration of 8.0 mg/dL or higher, and complications should be treated with urate-lowering drugs. Conventionally, allopurinol is used to treat hyperuricemia and gout, but it is necessary to adjust the dosage according to the degree of renal impairment. Uncommonly, allopurinol may have severe or fatal side effects. The non-purine xanthine oxidase inhibitor febuxostat undergoes hepatic metabolism and may require less dose adjustment in association with renal function. It is considered to be an alternative treatment for hyperuricemic patients with chronic kidney disease. Our experience suggests that low-dose febuxostat is a promising alternative to allopurinol for the treatment of gouty arthritis or tophi in peritoneal dialysis patients.

BACKGROUND: We performed a prospective, double blind study to compare the clinical effect of vertical infraclavicular brachial plexus block produced by 0.5% levobupivacaine and 0.5% ropivacaine for upper limb surgery. METHODS: We included 60 patients receiving upper limb surgery under infraclavicular brachial plexus block. The infraclavicular brachial plexus block was performed via the vertical technique with 30 ml of 0.5% levobupivacaine or 0.5% ropivacaine. We observed which nerve type was stimulated and scored the sensory and motor block. The quality of block was assessed intraoperatively. The duration of sensory and motor block and complications were assessed. RESULTS: There were no significant differences in frequencies of stimulated nerve type, evolution of sensory and motor block quality, or success of block. There were no significant difference in duration of sensory block, but duration of motor block was prolonged after 0.5% levobupivacaine. There were no complications. CONCLUSIONS: Both 0.5% levobupivacaine and 0.5% ropivacaine had similar effects in the vertical infraclavicular brachial plexus block.

OBJECTIVES: Alpha1-antitrypsin (AAT) is the main inhibitor of human neutrophil elastase, and plays a role in counteracting the tissue damage caused by elastase in local inflammatory conditions. The study evaluated the involvement of AAT in nasal allergic inflammation. METHODS: Forty subjects with mono-sensitization to Dermatophagoides pteronyssinus (Dpt) were enrolled. Twenty allergic rhinitis patients frequently complained of nasal symptoms such as rhinorrhea, stuffiness, sneezing, and showed positive responses to the nasal provocation test (NPT) with Dpt (Group I). The other 20 asymptomatic patients showed sensitization to Dpt but negative NPT (Group II). The levels of AAT, eosinophil cationic protein (ECP), and Dpt-specific IgA antibodies were measured in the nasal lavage fluids (NLFs), collected at baseline, 10 minutes, 30 minutes, 3 hours, and 6 hours after the NPT. Nasal mucosa AAT expression was evaluated with immunohistochemical staining from Group I and Group II. RESULTS: At baseline, only the Dpt-specific IgA level was significantly increased in the NLFs of Group I compared with Group II, while ECP and AAT levels were not significantly different between two groups. After Dpt provocation, AAT, ECP, and Dpt-specific IgA levels were significantly increased in the NLFs of Group I during the early and late responses. The protein expression level of AAT was mostly found in the infiltrating inflammatory cells of the nasal mucosa, which was significantly increased in Group I compared to Group II. CONCLUSION: The increment of AAT showed a close relationship with the activation of eosinophils induced by allergen-specific IgA in the NLFs of patients with allergic rhinitis after allergen stimulation. These findings implicate AAT in allergen-induced nasal inflammation.

This paper presents the design and application of a clinical data warehouse. The clinical data warehouse is built based on past 10 years of clinical data of Seoul National University Hospital. We extracted the clinical data from the database of hospital information system database and the results of Health 21 Project' , which is mainly composed of chief complaints, final diagnosis, discharge notes and survival data. By normalizing the terms of chief complaint, we are able to analyze the distribution patterns of symptoms within a diagnosis, and that of diagnosis related with a certain clinical symptom. Through our involvement with this project, we have learned that in order for a useful clinical data warehouse system, normalization and structured data entry is the key element of building clinical data warehouse.

BACKGROUND AND PURPOSE: This study investigated the seizure recurrence rate and potential predictors of seizure recurrence following antiepileptic drug (AED) withdrawal after resective epilepsy surgery in children with focal cortical dysplasia (FCD). METHODS: We retrospectively analyzed the records of 70 children and adolescents with FCD types I, II, and IIIa who underwent resective epilepsy surgery between 2004 and 2015 and were followed for at least 2 years after surgery. RESULTS: We attempted AED withdrawal in 40 patients. The median time of starting the AED reduction was 10.8 months after surgery. Of these 40 patients, 14 patients (35%) experienced seizure recurrence during AED reduction or after AED withdrawal. Half of the 14 patients who experienced recurrence regained seizure freedom after AED reintroduction and optimization. Compared with their preoperative status, the AED dose or number was decreased in 57.1% of patients, and remained unchanged in 14.3% after surgery. A multivariate analysis found that incomplete resection (p=0.004) and epileptic discharges on the postoperative EEG (p=0.025) were important predictors of seizure recurrence after AED withdrawal. Over the mean follow-up duration of 4.5 years after surgery, 34 patients (48.6% of the entire cohort) were seizure-free with and without AEDs. CONCLUSIONS: Children with incomplete resection and epileptic discharges on postoperative EEG are at a high risk of seizure recurrence after drug withdrawal. Complete resection of FCD may lead to a favorable surgical outcome and successful AED withdrawal after surgery.

Pneumocystis jirovecii pneumonia (PCP) can be a life-threatening opportunistic infection after kidney transplantation, occurring most frequently in the first 12 months with the symptoms of dyspnea, cough, fever, and hypoxia. Prophylaxis for PCP is usually applied during the first 3 months to 1 year after transplantation, but late onset incidence of PCP can be detected. We report on a patient who developed PCP 9 years after renal transplantation. The patient showed indolent onset of acute respiratory distress and was treated with trimethoprim-sulfamethoxazole and corticosteroid therapy. Previous rescue treatment of acute cellular rejection with ongoing maintenance of an elevated level of immunosuppressants may have predisposed the patient to PCP.

BACKGROUND/AIMS: The eradication rates of Helicobacter pylori infection have been reported to have decreased over the years due to antibiotics resistance. The aim of this study is to investigate the trend of eradication rates of first-line triple therapy for H. pylori over the past 13 year period, and to evaluate factors affecting H. pylori eradication in Daegu and Gyeongsangbuk-do, Korea. METHODS: A total of 2,982 patients with H. pylori infection who were treated with either 1 week or 2 weeks first-line therapy (proton pump inhibitor [PPI], amoxicillin, and clarithromycin) from January 1999 through December 2011 were included in this study. Data were collected by retrospectively reviewing the medical records. RESULTS: The overall H. pylori eradication rate was 87.2%. The eradication rates from 1999 to 2011 fluctuated between 78.0% and 95.7%, but no definite evidence of a decreasing tendency was seen over the 13 year period (p=0.113). Furthermore, there was no significant difference in the eradication rate according to the duration of therapy (p=0.592). However, there was a significant difference in the eradication rate among various PPIs (p<0.01). CONCLUSIONS: There was no decreasing trend in the H. pylori eradication rate over the past 13 years in Daegu and Gyeongsangbuk-do, Korea. There also was no difference in the eradication rates depending on duration of therapy. However, a significant difference was noted among various PPIs.
