PURPOSE: Clinical performance examination (CPX) has been used to assess clinical competence as one step of medical license examination. Initial CPX score of the fourth year medical student is important since it indicates how to prepare successfully for the final examination. This study was conducted to assess the predictors of CPX scores of the fourth year medical students who completed core clinical clerkship. METHODS: One hundred eleven fourth year medical students took a formative CPX in February. The score was compared with the scores of cognitive area and those of behavioral area which students had acquired in the past. We analyzed the correlation between the scores and determined the predictors of the fourth year CPX score. RESULTS: The fourth year CPX score showed stronger correlation with the scores of behavioral area than those of cognitive area. The significant predictors of fourth year CPX score included third year simple procedure exam score and third year clerkship CPX score. The risk factors for low fourth year CPX score included second year patient-physician interaction (PPI) score and third year CPX score after adjusted for age, sex, and school type. The risk factors of being selected as a low PPI score group of fourth year included low PPI scores of first, second, and third year exams. CONCLUSION: Our study highlights importance of educational balance between cognitive and behavioral areas. To improve clinical competence of final year medical students, clinical interview training using standardized patient with other modules is to be enhanced and initiated early in the medical curriculum.

BACKGROUND: Helicobacter pylori(H. pylori) is an important etiologic agent for chronic active gastritis and plays a role in the pathogenesis of peptic ulcer and stomach cancer and recently lymphomas occurring in mucosa associated lymphatic tissue. At present, H. pylori infection associated gastritis was estimated about 80% among the cause of chronic gastritis. In this study, we tested Polymerase Chain Reaction (PCR) assay to detect H. pylori infection in gastric biopsy specimens. This results were compared with results obtained by other tests. METHODS: A total of 70 patients with dyspepsia were evaluated for H. pylori infection through the use of PCR, culture and serologic tests. The study population had an age of 12 to 80 years(median 46.4), there were 31 males and 39 females. We tested PCR using H. pylori detection kit(TM) (Bioneer, Korea) and anti-H. pylori anti-body EIA using GAP test IgG and IgM(TM)(BIO-RAD, USA). We used anaerobic jar without catalyst for the microaerophilic condition. RESULTS: The positive result by PCR assay for diagnosis of H. pylori infection in gastric specimens was 71.4% in total of 70 patients, which the gastritis, peptic ulcer and gastric cancer were 63.2%, 77.8% and 85.7%, respectively. Among 10 gastrectomy specimens of stomach cancers, the detection rate of H. pylori infection by culture was 50% and the PCR assay was 100%. The detection rate of If pylori IgG and IgM antibodies by commercially available GAP test IgG and IgM EIA were 64.3%, respectively, and IgG or IgM were 85.7%. CONCLUSIONS: The serologic study was sensitive but it was appeared that the high false positive (75%) and false negative (25%) rate and could not confirm current infection. The PCR assay was shown to be more sensitive, rapid and easy to treat specimen for the detection of H. pylori infection than conventional methods such as culture and serologic test in dyspeptic patients.

Anaplastic lymphoma kinase (ALK) rearrangement, is a kind of driver mutation, accounts for 3%-5% of non-small cell lung cancer (NSCLC). NSCLC patients harboring ALK fusion genes have distinct clinical features and good response to ALK inhibitors. Metastasis from lung cancer to the ovary has rarely been known. We report a case of a 54-year-old woman with bilateral ovarian metastases from ALK rearranged NSCLC. She underwent bilateral salpingo-oophorectomy for ovary masses, which were progressed after cytotoxic chemotherapy although primary lung mass was decreased. Histopathological examination of the ovary tumor showed characteristic adenocarcinoma patterns of the lung and ALK rearrangement.

A 29-year old woman was admitted to the hospital with dyspnea and chest pain. She had undergone a craniotomy due to anaplastic astrocytoma 4 months ago and mass excision of right calf and vagina 3 months ago. The histopathological findings of masses were embryonal rhabdomyosarcoma. Echocardiography showed a highly mobile elongated mass in left atrium and the mass protruded through the aortic valve during systole. Histopathological examination of the resected cardiac tumor showed cells of embryonal rhabdomyosarcoma.

We report on a 64-year-old man with leptomeningeal metastasis (LM) from an epidermal growth factor receptor (EGFR)-mutated adenocarcinoma of the lung. He was treated with paclitaxel, cisplatin. After completion of chemotherapy, he complained of headache, nausea, and vomiting. EGFR-mutated tumor cells were identified from the cerebrospinal fluid (CSF). Second-line therapy with gefitinib, methotrexate was started. After receiving gefitinib for 4 weeks, he had no more headaches or vomiting. Eleven months after initiation of gefitinib, he developed headache and nausea. Chest computed tomography showed aggravation of bone metastasis. Third-line therapy was started with gemcitabine and carboplatin. Two weeks later, he experienced disorientation. After a fourth relapse within the central nervous system, the therapy was switched to erlotinib and significant improvement of LM was achieved. This case shows that LM can be diagnosed by detecting EGFR mutation in CSF and EGFR tyrosine kinase inhibitors are effective for LM from EGFR mutant non-small cell lung cancer.

BACKGROUND AND OBJECTIVES: Intensive lipid-lowering therapy with statins improves the clinical outcomes and patient survival and it reduces the progression of atherosclerosis. Intravascular ultrasound (IVUS) has been used for calculating the plaque volumes to evaluate the mechanisms that may be involved in the progression or regression of coronary artery disease. We used serial IVUS exams to assess the efficacy of rosuvastatin on plaque regression in angina patients who had a mild to moderate degree of vulnerable plaque burden. SUBJECTS AND METHODS: This study was a prospective, randomized, comparative study for lipid lowering therapy with using rosuvastatin 20 mg or atorvastatin 40 mg. IVUS was performed during the baseline coronary angiography and it was repeated after 12 months of treatment. The efficacy parameters included the changes in the atheroma volume and the lipid pool size as determined by IVUS. A total of 45 lesions in 30 patients were analyzed (rosuvastatin: 24 lesions in 16 patients vs. atorvastatin: 21 lesions in 14 patients). RESULTS: The low density lipoprotein (LDL)-cholesterol level was reduced from 121+/-45 mg/dL to 65+/-25 mg/dL in the rosuvastatin group (a 46% decrease, p<0.001), and from 127+/-37 mg/dL to 72+/-26 mg/dL in the atorvastatin group (a 43% decrease, p<0.001). The total atheroma and vessel volumes were significantly decreased, whereas the lumen volume was significantly increased from baseline to follow-up in both groups (for the rosuvastatin group: the total atheroma volume, 252+/-80 to 246+/-79 mm3, p<0.001; the vessel volume, 555+/-158 to 553+/-130 mm3, p<0.001; the lumen volume, 303+/-91 to 307+/-92 mm3, p<0.001, and for the atorvastatin group: the total atheroma volume, 288+/-98 to 283+/-98 mm3, p<0.001; the vessel volume, 607+/-165 to 604+/-166 mm3, p<0.001; the lumen volume, 319+/-71 to 321+/-73 mm3, p<0.001). The follow-up LDL-cholesterol level was correlated with the change in the total atheroma volume (r=0.577, p<0.001), the change in the percent atheroma volume (r=0.558, p<0.001) and the change in the lipid pool size (r=0.470, p=0.001). CONCLUSION: Both rosuvastatin 20 mg and atorvastatin 40 mg could contribute to the regression of lipid-rich plaque. The follow-up LDL-cholesterol level is related to the regression and stabilization of vulnerable coronary plaque.
