Torsades de pointes, a polymorphic ventricular tachycardia associated with prolonged QT interval, is a well-known life-threatening arrhythmia, which has been found to be induced by various causes such as drugs, electrolyte imbalances, and severe bradycardia. Cisapride is a gastrointestinal prokinetic drug, which is widely used to treat gastroesophageal reflux disease or other functional gastrointestinal disorders. Cisapride can cause torsades de pointes and cases of torsedes de pointes induced by cisapride have been reported in other countries. Cases of torsades de pointes associated with antihistamine drugs have been reported in Korea, however, cisapride-induced torsades de pointes case has not been reported. We report a case of 31 year-old female patient who experienced repeated loss of consciousness due to cisapride-induced torsades de pointes.

PURPOSE: The purpose of this study was to describe nurses' recognition of, and practice level in management of general nosocomial infections, and methicillin resistant staphylococcus aureus (MRSA) and vancomycin resistant enterococci (VRE) infections. METHODS: A self-administered questionnaire was used to collect data. Data were collected on June, 2003 from 190 nurses in one university affiliated hospital located in Suwon. RESULTS: The mean score for nurses' recognition of general nosocomial infection control was 3.57, MRSA control was 3.54, and VRE control was 3.86. The mean score on practice for control of general nosocomial infection was 3.19, for MRSA control, 3.20, and for VRE control, 3.63. There were statistically significant relationships between the recognition level and practice level for general nosocomial, MRSA, and VRE infection control. According to the general characteristics of the nurses, the mean scores for both recognition and practice were higher for those nurses who had had infection control education, for those who had worked longer in nursing, and for those who worked in the ICU. CONCLUSION: It is suggested that appropriate hospital infection control programs should be developed through continuous education and practice to improve nurses' level of the practice in general infection control, and especially in MRSA and VRE infection control.

Vascularized fibular graft is one of the treatment option for avascular necrosis of femoral head (ANFH) and has been known as providing a strut mechanical support and new vascular bed. It is very important to evaluate a healing process in femoral head after vascularization procedure. But a plain radiographic finding has a problem to assess pathological changes of ANFH treated with vascularized fibular graft. Authors analyzed chronogical changes of Tc-99m-HDP bone scan in 31 cases of ANFH treated with vascularized fibular graft from April, 1991 to May, 1994 and following results were obtained. l. Until 2 months after surgery, no change in size of cold defect area and no significant change in extent of RI uptake in reactive zone were noted. 2. During 2 months and 6 months after surgery, slight decrease in size of cold defect area and minimal changes in extent of RI uptake in reactive zone were observed. 3. During 6 months and 12 months after surgery, size of cold defect area decreased to 1/2 and changes in extent and degree of RI uptake in reactive zone were observed. 4. During 1 year and 2 years after surgery, size of cold defect area were minimal and sometimes faded away. RI uptake with decreased density in reactive zone broadened and moved to subchondral area. 5. After 2 years after surgery, cold area faded away and small increased RI uptake were observed in same site. In conclusion, Tc-99m-HDP bone scan which is economic and easily applicable in a patient is very useful for follow up study in ANFH treated with vascularized fibular graft.

OBJECTIVE: It is well known that fresh blastocyst transfer results in better pregnancy outcomes with a smaller number of transferred embryos compared with cleavage stage embryo transfer. However, in terms of frozen-thawed blastocyst transfer, only a few studies are available. We aimed to evaluate clinical outcomes of frozen-thawed embryo transfer (FET) with blastocysts. METHODS: Retrospective analysis of FET cycles with blastocysts (B-FET) between Jan 2007 and June 2009 was performed. Age-matched FET cycles with cleavage stage embryos (C-FET) during the same period were collected as controls. A total of 58 B-FET cycles were compared with 172 C-FET cycles and also compared with those of post-thaw extended culture blastocysts from frozen pronuclear stage embryos (22 cycles). RESULTS: There was no difference in the patient characteristics of each group. The embryos' survival rates after thawing were comparable (>90%) and there was no difference in the implantation rate or clinical and ongoing pregnancy rate among the three groups. CONCLUSION: In FET, blastocyst transfers may not present better pregnancy outcomes than cleavage stage embryo transfers. A further large-scale prospective study is needed.

Squamous eddy, focal necrosis, focal hemorrhage, and acute and chronic inflammation are common and reliable indicators of irritation. Squamous eddy is most commonly seenin inverted follicular keratosis, but it may be found on occasion in other conditions. Herein we describe a case of dilated pore with the feature of squamous eddies.

A case of pregnancy associated osteoporosis in a 26 year old woman with backache and vertebral com-pression fracture is presented. The radioactive 45-Ca uptake test showed a disturbance in intestinal calcium absorption. The bone densitometry measured by dual photon absorptiometry revealed severe osteoporosis the entire lumbar spine. After months without therapy, bone mineral density of the lumbar spine and femur were increased markedly and spontaneously.

Lipoblastoma is a rare benign mesenchymal tumor that occurs primarily in infancy and childhood. There are two types of lipoblastoma: focal or diffuse (lipoblastomatosis). This is typically located in the extremities, and less frequently in the trunk, head and neck, and the retroperitoneum. Lipoblastoma is a tumor with a good prognosis with no reported metastasis, despite of its potential for local invasion, local recurrence and rapid growth. Complete surgical resection is essential for treatment, and long term follow up is needed.

Tumor of the trachea are uncommon. Trachea tumor are usually diagnosed late in their natural history, because the tracheal lumen may be extensively involved before symptoms occur, and because symptoms may be confused with those of asthma. Some 19% to 29% of the trachea tumor have laryngeal or lung malignancy. Squamous carcinoma is by far the most frequent among tracheal tumor, although adenocarcinoma and oat cell carcinoma have been described so. Oat cell carcinoma in the trachea are aggressive tumors as. they are in the lung and elsewhere. Oat cell carcinoma as well as squamous cell carcinoma are related with tobacco exposure. We presented a case of small cell carcinoma nearly obstructing the trachea and right main bronchus which was partially removed after bronchoscopic ethanol injection, along with a review of the literature.
