PURPOSE: The aim of this study was to confirm the efficacy and safety of regorafenib for advanced gastrointestinal stromal tumors (GISTs) reported in the GRID phase III trial in Korean patients. MATERIALS AND METHODS: Fifty-seven Korean patientswith advanced GISTwho experienced both imatinib and sunitinib failure were enrolled in the management access program between December 2012 and November 2013 and treated with regorafenib (160 mg orally once daily in a 3 weeks on/1 week off). RESULTS: None of the patients achieved a complete or partial response while 25 patients (44%) showed stable disease for ≥ 12 weeks. With a median follow-up of 12.7 months (range, 0.2 to 27.6 months), the median progression-free survival and overall survival were 4.5 months (95% confidence interval [CI], 3.8 to 5.3) and 12.9 months (95% CI, 8.1 to 17.7), respectively. Interestingly, 15 patients (26%) experienced an exacerbation of their cancer-related symptoms (abdominal pain in eight and abdominal distension in five) during the rest period for regorafenib, but all were ameliorated upon the resumption of regorafenib. The most common grade 3 or 4 adverse event was a hand-foot skin reaction (25%). The regorafenib dose was reduced in 44 patients (77%) due to toxicity, which manifested mainly as a hand-foot skin reaction (n=31). CONCLUSION: This study confirmed the efficacy and safety of regorafenib for advanced GIST after imatinib and sunitinib failure in Korean patients. Considering the exacerbation of the cancer-related symptoms observed during the rest periods, further exploration of the continuous dosing schedule of regorafenib is warranted in future clinical trials.

BACKGROUND: The aim of this study was to evaluate antibiotic consumption by adult patients at a single university hospital in Korea between 2001 and 2012. METHODS: We used the 2004 World Health Organization Anatomical Therapeutic Chemical Classification System definition of defined daily doses (DDD) per 1,000 patient-days to calculate the annual antibiotic consumption for 18 antibiotic groups. Chi-square linear-by-linear analysis was performed to evaluate antibiotic consumption trends for each group. RESULTS: Average annual antibiotic consumption during 2001-2012 was 644.6 DDD/1,000 patient-days (standard deviation, 33.3 DDD/1,000 patient-days). Although no statistically significant change was observed during the study period, consumption of first- and second-generation cephalosporins, and aminoglycosides was significantly decreased, while that of beta-lactam/beta-lactamase inhibitors, fourth-generation cephalosporins, carbapenem, glycopeptide, linezolid, colistin, and quinolone increased significantly. CONCLUSION: The total amount of prescribed antibiotics did not change, but the use of broad-spectrum antibiotics increased during the study period.

A prostatic abscess is a rare, but potentially serious disease. The mainstay of treatment for the prostatic abscess is antibiotic administration and drainage. Here, we experienced a 66-year-old man with a prostatic abscess caused by Providencia rettgeri, which has not been reported as a pathogenic agent of a prostatic abscess. He was cured using antibiotics, without surgical drainage. This case suggests that the appropriate selection of patients for antibiotic therapy may provide an excellent prognosis.

Fournier's gangrene is a rare, rapidly progressive, necrotizing fasciitis of the genital, perianal and perineal regions. It is usually caused by a synergistic infection of aerobic and anaerobic organisms. A 51-year-old male patient with diabetes mellitus and chronic renal insufficiency on peritoneal dialysis was admitted with severe scrotal pain and swelling that lasted 4 days. An emergent non-contrast-enhanced computed tomography revealed extensive gas formation, fatty haziness and edema in the left scrotal and inguinal area. The patient was successfully treated with immediate surgical debridements and antibiotics. Streptococcus anginosus group Streptococcus anginosus was isolated from surgical wound cultures and identified with biochemical identification methods and direct sequencing of DNA. Herein, we report a rare case of Fournier's gangrene caused by S. anginosus. We also review the relevant literature

Congenital hemolytic anemia is mainly developed due to intrinsic defects of erythrocytes, but in some cases the cause of hemolytic anemia is unclear. Gilbert's syndrome shows mild, chronic unconjugated hyperbilirubinemia that is due to reduced UDP glucuronosyltransferase (UGT-1A1) activity and this develops because of UGT-1A1 gene mutation. We report here on a case of severe hyperbilirubinemia in a 17-year-old male who was diagnosed with congenital hemolytic anemia of an unknown cause combined with Gilbert's syndrome.

Percutaneous nephrolithotomy (PCNL) has largely replaced open surgical intervention for the management of renal pelvis calculi as it reduces patient morbidity and shortens hospital stay. However, major complications such as hydrothorax or pneumothorax can be encountered uncommonly. A 64-year-old, 48 kg, female patient underwent PCNL under general anesthesia. The preoperative chest X-ray showed normal findings. Elevated airway pressure was noted and then breathing sounds were not audible on the right lung field during the procedure. A chest X-ray and chest computerized tomographic scan, taken immediately after the operation, showed massive hydrothorax and total collapse in the right lung. After drainage of the pleural effusion via chest tube, the patient recovered completely. Anesthesiologists should be aware that hydrothorax can occur during the PCNL procedure and must be prepared to intervene quickly.

BACKGROUND: Campylobacter is the most common bacterial cause of food-borne infection in developed countries, and handling or eating of contaminated poultry products was reported as the major cause of human campylobacteriosis in sporadic cases. This study was performed to investigate the prevalence of Campylobacter in patients with diarrhea and raw chickens of grocery, and identify the species by multiplex PCR and determine the genotypes of isolates by SmaI pulsedfield gel electrophoresis(PFGE) profiles. METHODS: Eight hundred and fifty six stool specimens obtained from 773 hospitalized patients with diarrhea and 16 raw chickens purchased from grocery were tested. Karmali's charcoal based selective medium and Campylobacter enrichment broth were used for isolation of Campylobacter from patients and chicken, respectively. And membrane filter method with sheep blood agar was also used in both two cases. Isolates were indentified with PCR, PCR-RFLP, and biochemical test. And genotypes were determined with SmaI PFGE profile analysis. RESULTS: A total of 13 Campylobacter strains(1.7%) were isolated from 856 stool specimens of 773 patients with diarrhea, nine isolates were C. jejuni and four were C. coli. All of 16 raw chickens were contaminated with Campylobacter spp., and both of C. jejuni and C. coli were detected from eight chickens. From the SmaI-digested PFGE profile analysis of nine C. jejuni strains and four C. coli strains isolated from patients, eight types and four types of PFGE profile were obtained, respectively. And 15 types and seven types of PFGE profile were obtained from 23 of C. jejuni and 11 of C. coli which strains were isolated from chicken samples, respectively. The several isolates showing the different PFGE patterns were detected in the same chicken. Three PFGE patterns of C. jejuni isolated from patients were observed in the chickens. One type of C. coli PFGE profiles of the patient's isolates were the same as that of chicken. CONCLUSIONS: The prevalence of Campylobacter infection is not high compared to the other countries, but most of raw chickens are contaminated with Campylobacter spp. Several genotypes of C. jejuni and C. coli are contaminated in the single chicken. The PFGE patterns of some human isolates are the same as those of chicken so that human infection may be originated from the chicken. But the reason of low infection rate in human in spite of the very high contamination rate of chicken should be clarified in the near future

Basal cell adenocarcinoma is an epithelial neoplasm which is cytologically and histomorphologically similar to basal cell adenoma but is different because of the infilitrative growth. This tumor, a rare salivary gland tumor newly classified as basal cell adenocarcinoma by the WHO in 1991, is infiltrative, locally destructive and tends to recur but metastasis is less common. The differential diagnosis includes basal cell adenoma, adenoid cystic carcinoma, and basaloid squamous carcinoma. Nearly 90 percent of these tumors occurr in the parotid gland and can be classified into low grade carcinomas with a relative good prognosis. Basal cell adenocarcinoma of minor salivary gland is very rare and has a less favorable clinical course compared with that of the major salivary glands. This is a case of basal cell adenocarcinoma occurring at the minor salivary gland of the soft palate. We treated this patient with block excision and adjunctive radiation therapy.

A new surgical approach to the area of the infratemporal fossa and parapharyngeal space is described. This approach results in a wide-field exposure of the infratemporal fossa, pterygomaxillary space and parapharyngeal space. We used two osteotomies on the patient's mandible and temporary resection of zygomatic arch for superior margin of tumor. Lower lip splitting was not needed because the incision was started in the frontal scalp, curved in front of and below the external auditary canal, and extended anteriorly to the greater horn of hyoid bone on the neck along a skin crease. We had good results without sacrifice of the facial nerve, mandibular function and sensory supply of the face and oral cavity.
