BACKGROUND AND OBJECTIVES: The relationship between operator volume and outcomes of percutaneous coronary intervention (PCI) in patients with ST-elevation myocardial infarction (STEMI) has not been fully investigated. We aimed to investigate the relationship between operator PCI volume and in-hospital outcomes after primary PCI for STEMI. METHODS: Among the total of 44,967 consecutive cases of PCI enrolled in the Korean nationwide, retrospective registry (K-PCI registry), 8,282 patients treated with PCI for STEMI by 373 operators were analyzed. PCI volumes above the 75th percentile (>30 cases/year), between the 75th and 25th percentile (10–30 cases/year), and below the 25th percentile (<10 cases/year) were defined as high, moderate, and low-volume operators, respectively. In-hospital outcomes including mortality, non-fatal myocardial infarction (MI), stent thrombosis, stroke, and urgent repeat PCI were analyzed. RESULTS: The average number of primary PCI cases performed by 373 operators was 22.2 in a year. In-hospital mortality after PCI for STEMI was 571 cases (6.9%). In-hospital outcomes by operator volume showed no significant differences in the death rate, cardiac death, non-fatal MI, and stent thrombosis. However, the rate of urgent repeat PCI tended to be lower in the high-volume operator (0.6%) than in the moderate-(0.7%)/low-(1.5%) volume operator groups (p=0.095). The adjusted odds ratios for adverse in-hospital outcomes were similar in the 3 groups. Multivariate analysis also showed that operator volume was not a predictor for adverse in-hospital outcomes. CONCLUSIONS In-hospital outcomes after primary PCI for STEMI were not associated with operator volume in the K-PCI registry.

A clonorchiasis case in a captive leopard cat, Prionailurus bengalensis euptilurus, was confirmed by ultrasonographic findings and egg morphologies found in the bile juice sample in the Korea. The leopard cat was introduced from the wild habitat of Gyeongsangnam-do, to Cheongju Zoo in Cheongju-si, Chungcheongbuk-do, Korea in August 2014. Physical examinations were basically performed for quarantine and check-up health. The cat was comparatively good in health except anorexia. The cyst-like bile duct dilation and the increased echogenicity of gall bladder wall and hepatic parenchyma were observed by ultrasonography. Ultrasound-guided needle biopsy was conducted for collecting bile juice and the specimens were observed under light microscope. The numerous small trematode eggs were detected in the bile juice sample of the light microscopy. The eggs were 25–33 (28±3) μm by 18–22 (20±1) μm in size and showed typical characteristics of Clonorchis sinensis egg, i.e., a dominantly developed operculum, shoulder rim and dust-like wrinkles in surface. To treat the liver fluke infection, 20 mg/kg of praziquantel was orally administered only once to the case. Follow-up studies including fecal examinations were conducted during 2 years after treatment. But no more eggs were detected from the case. In the present study, we described the first clonorchiasis case of leopard cat, which was confirmed by ultrasonographic findings and egg morphologies from the bile juice sample in Korea.

PURPOSE: The aims of this study were to review our cases of missed Monteggia fracture treated by open reduction of the radial head with or without ulnar osteotomy and to investigate the indications for open reduction alone in surgical treatment of missed Monteggia fracture. MATERIALS AND METHODS: We retrospectively reviewed 22 patients who presented with missed Monteggia fracture. The patients' mean age at the time of surgery was 7.6 years. The mean interval from injury to surgery was 16.1 months. The surgical procedure consisted of open reduction of the radiocapitellar joint followed by ulnar osteotomy without reconstruction of the annular ligament. The mean period of follow-up was 3.8 years. Radiographic assessment was performed for the maximum ulnar bow (MUB) and the location of the MUB. Clinical results were evaluated with the Mayo Elbow Performance Index and Kim's scores. RESULTS: Five patients underwent open reduction alone, and 17 patients underwent open reduction and ulnar osteotomy. When the MUB was less than 4 mm and the location of the MUB was in the distal 40% of the ulna, we could achieve reduction of the radial head without ulnar osteotomy. The radial head was maintained in a completely reduced position in 21 patients and was dislocated in one patient at final follow-up. CONCLUSION: Open reduction alone can be an attractive surgical option in select patients with missed Monteggia fracture with minimal bowing of the distal ulna. However, ulnar osteotomy should be considered in patients with a definite ulnar deformity.

Gastric cancer patients with acute disseminated intravascular coagulation experiences a rare but severe complication resulting in a dismal prognosis. We report a case of advanced gastric cancer complicated with disseminated intravascular coagulation with intractable tumor bleeding which was successfully treated with chemotherapy consisting of 5-fluorouracil and oxaliplatin. The patient was a 63-year-old man who complained of abdominal pain, melena, and dyspnea on 24 November 2010. We diagnosed stage IV gastric cancer complicated by disseminated intravascular coagulation. Gastric tumor bleeding was not controlled after procedures were repeated three times using gastrofiberscopy. With the patient's consent, we selected the 5-fluorouracil and oxaliplatin combination chemotherapy for treatment. After one cycle of 5-fluorouracil and oxaliplatin therapy, symptoms of bleeding improved and the disseminated intravascular coagulation process was successfully controlled. The primary tumor and multiple metastatic bone lesions were remarkably shrunken and metabolically remitted after eight cycles of chemotherapy. In spite of progression, systemic chemotherapy is effective in disease control; further, the patient gained the longest survival time among cases of gastric cancer with disseminated intravascular coagulation.

OBJECTIVE: To observe the changes in protein expression induced by botulinum toxin A (BoNT-A) injection and to characterize the molecular and cellular action of mechanisms of BoNT-A injection on skeletal muscles using proteomic elements as biomarkers. METHODS: BoNT-A was injected into left gastrocnemius muscles of 12 Sprague-Dawley rats (2 months of age) at a dosage of 5 units/kg body weight. For the controls same volume of normal saline was injected to right gastrocnemius muscle of each rat. Muscle samples were obtained at 4 time points (3 rats per time point): 3, 7, 14, and 56 day post-injection. To reveal the alterations in muscle protein, we performed 2-dimensional electrophoresis (2DE) and compared Botox group and normal saline group at each time point. Altered protein spots in 2DE were identified using matrix-assisted laser desorption/ionization-time-of-flight mass spectrometer (MALDI-TOF MS) proteomics analysis. RESULTS: Compared with normal saline group, 46 protein spots showed changed protein expression. Twelve protein spots demonstrated increased volume and 34 protein spots demonstrated decreased volume. Among spots of decreased volume, 17 spots showed statistically significant differences. Thirty-eight identified proteins were associated with alterations in energy metabolism, muscle contractile function, transcription, translation, cell proliferation, and cellular stress response. CONCLUSION: BoNT-A gives influences on muscle contractile function and energy metabolism directly or indirectly besides neurotoxic effects. Proteomic expression provides better understanding about the effect of BoNT-A on skeletal muscle.

PURPOSE: Parenting stress could be different among mothers of children with brain tumors. The aim of this study was to explore subtypes of children with brain tumor based on their intellectual and psychological characteristics and to compare the parenting stress of their mothers among the subtypes. METHODS: Latent profile analysis was conducted on the Verbal IQ, Performance IQ, and the scores of Social Problem, Internalization Behavior Problem, and Externalization Behavior Problem in a total of 90 children with brain tumors. Furthermore, the mothers' parenting stress was compared among the explored subtypes. RESULTS: Four-categorization appeared the best way to describe the intellectual and psychological presentation of the children with brain tumors and they are as follows; (1) Borderline Intelligence-Socially Maladjusted (B-SM: 24.4%), (2) Average Intelligence-Internalization Behavior Problem (A-I: 44.4%), (3) Average Intelligence-Normal Behavior (A-N: 18.9%), and (4) Retarded Intelligence-Global Maladjusted (R-GM: 12.2%). Mothers of R-GM group reported higher levels of stress on total domain and the subfactors of distractibility and adaptability of Korean Parenting Stress Index compared to mothers of A-N group, and the highest level of stress on spouse subfactor among the mothers of all subtypes. Mothers of subtypes with either intellectual or psychological problems showed higher level of stress on demandingness subfactor compared to mothers of A-N group. CONCLUSION: Eighty percents of children with brain tumor showed intellectual or psychological problems and the mothers of the children with both problems reported the highest parenting stress. The tailored services are needed to manage the parenting stress of mothers of children with brain tumors.

This study intended to identify the need for the legalization and development of a systematic program for physician assistants (PAs) by understanding the actual state of PA operation in hospitals. In 114 hospitals assigned as resident training hospitals for surgery, a survey was conducted on the personnel working as PAs in those hospitals; the survey included general personal information, working conditions, training time, and satisfaction. A total of 192 PAs in surgery at 35 hospitals responded to the survey. The types of PAs are Surgical Assistant, Clinical Physician Assistant, Wound Ostomy Care Nurse, Coordinator, and Clinical Research Coordinator. Types of work PAs preformed are surgical assistance, wound dressing, educating patients, overlooking consultation, doing paper works, writing operation records, and confirming examination results which were ordered. The satisfaction level for the position which PAs hold were 29.1% and and satisfaction level which doctors see towards PA was 15%. The role and the job descriptions of PAs are not clear cut, there are many discrepancies among hospitals we studied. As a result, legalization and the implementation of standardized role of PAs will lead to increase level of satisfactions in the work force and the quality of work which PAs perform will be greater.

OBJECTIVES: This study was conducted to compare emotional problems in children with neurosurgical diseases prior to surgery as well as levels of parenting stress experienced by mothers of children treated with surgery and those without surgery. The goals was to provide a basis on which comprehensive treatment interventions could be established. METHODS: Subjects included 78 elementary school children who visited the Department of Pediatric Neurosurgery as well as their mothers. The Children's Depression Inventory (CDI) and the Revised Children Manifest Anxiety Scale (RCMAS) were administered to children. The Parenting Stress Indexs (PSI) and Beck Depression Inventory (BDI) were administered to their mothers. RESULTS: The children with neurosurgical diseases showed higher levels of depression prior to surgery. In their mothers, parenting stress was relatively higher and parenting competence was lower. In particular, for those children who underwent surgery, depression was significantly higher. Specifically, they exhibited more negative expectations, and negative self-image. In mothers of children who underwent surgery, depression was significantly higher. CONCLUSION: Our results suggest higher levels of emotional distress and parental stress in children who undergo neurosurgical operations and their mothers, respectively. Based on this, the necessity for surgical and comprehensive psychological intervention is suggested.

BACKGROUND: Viruria is frequently detected in patients who have had hemorrhagic cystitis (HC) following allogeneic hematopoietic stem cell transplantation (allo-HSCT). Urinary viruses, especially BK virus, have been suggested as a cause of HC following allo-HSCT, therefore antiviral therapy is emerging as a therapeutic approach for its treatment. METHODS: Adult HC patients who underwent allo-HSCT from January 2005 to March 2006 at a single institution were enrolled. We performed a PCR-based assay for BK virus, JC virus, and CMV virus in urine obtained from the patients to determine the incidence of viruria, and the type of virus detected in the urine, and the effect of treatment with cidofovir on HC. RESULTS: Of 155 patients that received allo-HSCT during the study period, 22 (14.2%) experienced HC. A viral study of urine obtained from 19 of these 22 patients revealed that 16 (84.2%) had viruria. Eleven patients had grade III-IV HC, 5 of which were treated with intravenous cidofovir. Three of the HC patients who underwent treatment responded to cidofovir, 1 had no response, and 1 had a complete response followed by recurrence. CONCLUSION: Most adult HC patients (84.2%) had viruria following allo-HSCT, however the response rate to antiviral therapy with intravenous cidofovir for the treatment of high grade HC (grade III-IV) was 80%. Therefore, antiviral therapy should be considered if high grade HC does not respond to hyperhydration and transfusional support.
