A 17-year-old male patient was referred with symptoms of dyspnea. Multi-detector computerized tomography (MDCT) and echocardiography evaluation revealed quadricuspid aortic and pulmonary valves, an atrial septal defect (ASD), and pulmonary stenosis. We closed the ASD using a bovine patch and performed a commissurotomy of the pulmonary valve. Quadricuspid semilunar valves are very rare congenital abnormalities that are reported to occur nine times more frequently in the pulmonic valve than in the aortic valve. According to the Hurwitz and Roberts classification, the aortic valve was type A, and the pulmonic valve was type B. The aortic valve had normal function, but the pulmonic valve was stenotic and had abnormal function.

Sternal fracture is relatively common after blunt chest trauma, and this usually resolves without complication. But acute extrapericardial tamponade caused by sternal fracture and injury to the internal mammary artery secondary to blunt chest trauma is very rare. We report here on two cases of acute extrapericardial tamponade that were caused by blunt chest trauma.

BACKGROUND: The purpose of this study was to identify factors associated with recurrent pneumothorax after wedge resection in primary spontaneous pneumothorax in our hospital. MATERIAL AND METHOD: Two hundred thirty-five consecutive patient (98% males; mean age, 23.9+/-4.5 years) who had undergone video-assisted thoracoscopic surgery (VATS) were reviewed retrospectively. The two groups were divided as follows: group A, non-recurrent patients (225 patients [96%]); and group B, recurrent group (10 patients [4%]); the risk factors were compared between the two groups. The single and multiple factors that influenced the recurrence rate were analyzed using Cox's proportional hazard model. RESULT: There were no significant differences between the recurrent and non-recurrent groups in terms of gender, smoking, site of recurrence, degree of collapse, operative time, and number or weight of resected bullae. The recurrence rate was significantly more common in the following: younger ages, increased height/weight ratio, longer initial air leakage period, and shorter duration of chest drainage. Early aggressive exercise (<30 days) of patients after wedge resection increased the tendency for recurrence. CONCLUSION: Thoracoscopic wedge resection does not have a higher recurrence rate than open thoracotomy. However, young age, height/weight ratio, continuous air, and duration of chest tube placement were risk factors for a recurrent pneumothorax.

BACKGROUND: The purpose of this study is to investigate the positive rates of screening tests for inherited metabolic disorders, set cutoff values, and report the actual status of internal quality controls in LabGenomics Clinical Laboratories by using LC-MS/MS system. METHODS: We use Agilent 1260 Infinity HPLC System (Agilent Technologies, USA) for liquid chromatography, and API 2000 (AB Sciex, Canada) for MS/MS system. We set up screening tests for 55 diseases, which include metabolic disorders of 25 amino acids, 16 organic acids, and 14 fatty acids. RESULTS: We determined the analyte cutoff values as 99.9 or 0.1 percentiles in 15,000 newborn samples. The total number of samples tested from January 2012 to September 2014 was 119,948; of these, 6,681 were repeated. Of the repeated samples, 713 were presumed to be positive in the screening tests. Repeat screening with newly obtained dried blood spot specimens was recommended for these 713 samples and 600 specimens were obtained. Thus, the recall rate was 0.5% (600/119,948) for all samples and 84.2% (600/713) for the samples presumed to be positive in the screening tests. About 70 samples, that is, 0.06% of the total samples and 11.7% of the "reobtained" samples, again tested positive; we recommended confirmatory tests for these samples. CONCLUSIONS: We have presented data on the status of neonatal screening tests for inherited metabolic disorders using LC-MS/MS, including positive rates and recall rates of screening tests, set up cutoff values and reported the actual status of internal quality controls in a clinical laboratory in Korea.

STUDY DESIGN: Case report. OBJECTIVES: To report a huge epidural hematoma after epidural neurolysis. SUMMARY OF LITERATURE REVIEW: No complications have been reported regarding to hematoma formations after neurolysis using NaviCath(R). MATERIAL AND METHODS: A 67-year-old male with normal serum coagulation parameter experienced excruciating back and leg pains after neurolysis using NaviCath(R). RESULTS: After performing prompt multilevel laminotomy with hematoma evacuation, the patient recovered from pains without any neurological sequelae. CONCLUSIONS: It is important to be cautious while performing neurolysis with NaviCath(R) to avoid the epidural hematoma. Surgical treatment is an effective option to resolve the spinal epidural hematoma.

To find out the different cognition of the members of medical school about the importance of graduate outcomes such as 'clinical performance, communication, supporting patients, professionalism, problem solving and research, self-development', a survey applied with self-report method was conducted with 110 faculties, 132 students (71 premedical 2nd graders and 61 medical 2nd graders), and 30 parents about graduate outcomes and sub-outcome competences. Parents usually thought highly of the importance of graduate outcomes, while medical second graders comparatively regarded them as less important. Among graduate outcomes, 'clinical performance' was definitely considered the most important and was followed by 'communication'. As for 'self-development', parents and premedical 2nd graders regarded it as important, while faculty and medical 2nd graders had lower awareness about its importance. As to the suboutcome competences, faculty generally had lower awareness about their importance compared to students and parents.

Dermoid cysts are the most common type of ovarian neoplasms occurring during a woman's reproductive life and account for 25% of all premenopausal ovarian neoplasms. Intraoperative spillage of dermoid cyst materials may lead to febrile morbidity, ileus, peritonitis, adhesion or fistula formation. Rarely, malignant element spillage, if present, may also lead to cancer dissemination. The management of dermoid cyst is controversal. Recently, laparoscopic surgery for ovarian cysts has been increasingly accepted. But, in view of the high risk of intraperitoneal rupture of large sized cysts, many surgeon still prefer the laparotomic approach. Recently, we did laparoscopic salphingo-oophorectomy to the patient having 20cm sized dermoid cyst. Intraoperative spillage of cyst material occurred, but patient recovered without any postoperative complication. So, we present this case with brief review of the literatures.

Primary intestinal lymphangiectasia is a congenital lymphatic disorder characterized by dilated intestinal lacteals resulting in lymph leakage into the small bowel lumen and responsible for protein losing enteropathy. As a result, generalized edema, hypoalbuminemia, and lymphocytopenia are clinically manifested. We could not find the reason by several examinations. Therefore, we performed double balloon enteroscopy (DBE), and intestnal lymphangiectasia was diagnosed histologically by a biopsy. DBE is a safe and effective method to diagnose small bowel lymphangiectasia. We report a case of primary intestinal lymphangiectasia, which occurred in a 54-year-old male patient with generalized edema and ascites.
