Six cases of nasal septum perforation were found among welders during periodic physical checkup in 1997. Considering the size, shape and margin, the perforations were assumed to have been occurred several years before of which the diameter were 8~15 mm. To investigate the cause of perforation, we reviewed the past history of preemployment, the results of annual working environment survey and the material safety data sheets of welding rods and steels with which they have dealt, and analyzed the concentration of several metals of welding fume and the concentration of blood and urinary chromium. In the result, we presupposed that the nasal septum perforations of welders were due to chronic exposure to low level hexavalent chromium and/or nickel, and report these cases with literatures review.

The HELLP syndrome(hemolysis, elevated liver enzymes, and low platelets) is a complication of severe preeclampsia or eclampsia and associated with increased maternal and perinatal mortality. Exact pathogenic mechanism is still unclear but the microangiopathic hemolytic anemia combined with endothelial cell damage is suspected to be closely associated with disease process. Variable degree of disseminated intravascular coagulation(DIC) may be accompanied with the HELLP syndrome. We report a case of postpartum HELLP syndrome. She is 24 year-old woman. She showed definite evidence of microangiopathic hemolytic anemia, DIC, elevated liver enzymes and acute renal failure. Liver biopsy revealed fatty change with focal fibrin like material deposition in the portal tract area. She recovered completely with conservative treatment in 2 weeks.

OBJECTIVE: This study was carried out to compare the clinical outcome of elective single cleavage-embryo transfer (eSCET) to that of elective single blastocyst-embryo transfer (eSBET) in human IVF-ET. METHODS: This study was a retrospective study which analyzed for 614 women who visited the Daegu Maria Clinic from August 2008 to December 2009. All were under 37 years old and had more than 8 mm of endometrial thickness on the day of hCG administration and at least one good quality embryo on day 3. The eSCETs were performed on day 3 (n=450) and the eSBETs were conducted on day 5 (n=164). RESULTS: The numbers of retrieved oocytes, fertilized oocytes, and day 3 good quality embryos were significantly lower in the eSCET group (12.1+/-6.0, 8.2+/-4.6, and 4.2+/-3.1, respectively) compared to the eSBET group (16.7+/-7.2, 12.1+/-5.0, and 8.5+/-4.5, respectively; p<0.001). However, the clinical pregnancy, implantation, on-going pregnancy, and live birth rates of the eSCET group (46.7, 46.9, 40.0, and 36.7%, respectively) were not statistically different from those of the eSBET group (51.2, 51.8, 45.1, and 43.9%, respectively; p=0.318, 0.278, 0.254, and 0.103, respectively). CONCLUSION: These results suggested that elective single embryo transfer should be performed regardless of the developmental stage to women less than 37 years old who had more than 8 mm of endometrial thickness on the hCG administration day and at least one good quality embryo on day 3 in order to reduce the twin pregnancy rate without reducing the whole pregnancy rate.

The characterisitic finding of hypertrophic cardiomyopathy is left ventricular hypertrophy without dilated chamber. Echocardiographic studies of patients with pheochromocytoma in the past have revealed both dilated and hypertrophic cardiomyopathies, as well as obstruction of the left ventricular outflow tract. We report this case because we experienced a pheochromocytoma patient who had reversible hypertrophic cardiomyopathy which might be related with circulating catecholamine level.

Pulmonary tumor thrombotic microangiopathy (PTTM) is a rare, malignancy-related complication that causes marked pulmonary hypertension, right heart failure, and death. We report on a patient with locally advanced breast cancer whose course was complicated by fatal PTTM based on clinical and laboratory findings.
