A case of arterial priapism was treated by superselective transcatheteric autologous clot embolization of cavernosal artery 25 days after blunt periheal trauma. No immediate improvement was noted but the priapism subsided on 48th day after the procedure. Normal physiclogic erectlie function was achieved on 53rd day after the procedure, and the period of postprocedure impotence was shortened, as compared with previously reported cases. Autologous blood clot embolization may be an effective treatment method even in delayed priapism, and superselective technique is thought to be more effective to shorten the postprocedure erectlie dysfunction

PURPOSE: The objectives of this study were to 1) explore nurses' attitudes toward death, coping with death, understanding and performance regarding end-of-life (EOL) care, 2) describe correlations among the above factors, and 3) determine the factors affecting nurses' EOL care performance. METHODS: Study participants were 187 nurses stationed at departments that post higher mortality than others such as the oncology department, intensive care unit (ICU) and emergency department (ED). Data were collected from three urban university-affiliated hospitals. Multi-dimensional measure was performed for study instruments such as "attitude toward death", "coping with death" and "understanding and performance regarding EOL care". Data were analyzed by using descriptive statistics, correlation, and multiple regressions. RESULTS: First, nurses showed significantly different attitudes toward death by age, religion, work unit and EOL care education. Younger nurses tend to score low on the understanding of EOL care, and ED nurses' score was lower than their peers at the oncology department and ICU. Second, EOL care performance was positively correlated with attitude toward death (P<0.001), coping with death (P=0.003) and understanding of EOL care (P<0.001). Third, nurses' EOL care performance was affected by work unit (P<0.001) and understanding of EOL care (P<0.001). CONCLUSION: Because nurses' performance was influenced by their work unit and understanding of EOL care, they should be provided with appropriate training to improve their understanding of death and EOL care according to work unit.

OBJECTIVE: To determine whether the follicle stimulating hormone(FSH) receptor gene mutation (C566T point mutation) is present in Korean women with premature ovarian failure and normal karyotype. METHODS: Genomic deoxyribonucleic acid(DNA) obtained from 40 patients with chromosomally competent premature ovarian failure and from 30 normal fertile women(control group) was amplified by polymerase chain reaction(PCR). PCR products were digested by the enzyme BsmI and polyacrylamide gel(PAG) elctrophoretic patterns of these enzyme-digested products were analyzed. The direct sequencing of PCR products was also performed. RESULTS: All patients with premature ovarian failure and 30 normal control women demonstrated homozygous, normal alleles with 51- and 27- base pairs fragments in PAG elctrophoresis. The absence of C566T point mutation in both group was confirmed by direct DNA sequencing. CONCLUSIONS: A C566T mutation in FSH receptor gene is rare in Korean women with premature ovarian failure and normal karyotype.

BACKGROUND: The objective of this article is to evaluate clinical outcomes of combined orbital floor and medial wall fracture repair using a three-dimensional pre-bent titanium implant in an East Asian population. METHODS: Clinical and radiologic data were analyzed for 11 patients with concomitant orbital floor and medial wall fractures. A combined transcaruncular and inferior fornix approach with lateral canthotomy was used for the exposure of fractures. An appropriate three-dimensional preformed titanium implant was selected and inserted according to the characteristics of a given defect. RESULTS: Follow-up time ranged from 2 to 6 months (median, 4.07 months). All patients had a successful treatment outcome without any complications. Clinically significant enophthalmos was not observed after treatment. CONCLUSIONS: Three-dimensional pre-bent titanium implants are appropriate for use in the East Asian population, with a high success rate of anatomic restoration of the orbital volume and prevention of enophthalmos in combined orbital floor and medial wall fracture cases.

Cortical spreading Depression(CSD) is a transient depression of neuronal activity that spreads across the cortical surface and is associated with profound changes in blood flow, extracellular ion concentration. Direct Current(DC) potentials and cell membrane potentials. One of the electrophysiological disturbance in the periinfarct surrounding is spontaneous occurrence of repeated CSD like DC shifts associated with increased energy demand. Due to restricted blood flow to the periinfarct border zone, elevated metabolic demand is potentially hazardous. So the authors designed this experiment to verify the correlation between periinfarct cortical spreading depression and ischemic volume following permanent middle cerebral artery(MCA) occlusion in rats. Sprague-Dawley rats(n=27) were anesthetized with 0.5~1% halothane, and artificially ventilated through a tracheal cannula. Arterial pressure, blood gases and body temperature were controlled. The middle cerebral artery(MCA) was occluded distally to the lenticulostriate branches. Measurements of CSD activity were made for 4 hours in each animal infarct volume was determined 6 hours later in 2,3,5-triphenyl tetrazolium chloride(TTC)- stained section. For 4 hours after MCA occlusion, the CSDs were found in all experimental animals with a range of 2~9 times. Those CSDs were of varying duration: "small"(1min) SDs and mean of total duration of SD was 10.5+/-10.3 min during 4 hours of MCA occlusion. Neuropathological evaluation of brain infarct in the rats, which had been allowed to survive for 6 hours after MCA occlusion showed a mean volume of 89.7+/-45.3 mm3. Serial observation of duration of CSD prologation of duration of CSD nor the frequency of CSD in the penumbral zone correlated with the volume of infarct.However total duration of CSD was slightly related with the infarct volume after 6 hours of the permanent MCA occlusion(r=0.414, p=0.0318) .

PURPOSE: Voice change after thyroidectomy has generally been the result of damage to the recurrent or superior laryngeal nerve. But many patients complain voice alteration without laryngeal nerve injury after thyroidectomy. The purpose of this study is to investigate whether strap muscle division results in any subjective or objective functional sequelae in voice, through long-term follow-up prospectively. METHODS: Twenty-two female patients who had undergone thyroid surgery between July 1998 and December 1999, were studied. The patients who were planned for neck dissection, who had benign laryngeal disease or vocal cord paresis, and whose vocal cord paresis were developed after thyroid surgery, were excluded from this study. Twelve patients had undergone thyroidectomy via retraction of strap muscle and ten patients had undergone thyroidectomy via cutting of strap muscle. For evaluation of voice, questionnaires for changes of voice, acoustics (fundamental frequency, jitter, shimmer, signal to noise ratio, noise to harmonic ratio, voice range), and aerodynamic (maximal phonation time) analyses were done. RESULTS: The subjective voice symptoms after thyroidectomy were disturbances of high pitch, singing, loud voice, and easy fatigue at phonation. There were no significant differences in voice parameters on acoustic and aerodynamic analyses between the strap muscle retraction group and the cutting group through long-term follow-up. CONCLUSION: We conclude that strap muscle division does not result in any subjective or objective functional problems in voice. We suggest that surgical division and reconstruction of these muscles should be employed routinely when operating on large, toxic or neoplastic glands.

PURPOSE: Clotting factor X deficiency is one of the least common coagulation disorders. The authors describe a case of cleft palate in a patient with a congenital clotting factor X deficiency. METHODS: In pediatric patients with a cleft palate, the coagulation problem is more worrisome, because they are more sensitive to blood than adults, and because postoperative bleeding can cause blood ingestion with subsequent vomiting, aspiration, and airway obstruction. To prevent hemorrhagic complications in the described case, fresh frozen plasma (FFP) was administered every 24 hours from the day before surgery to the second postoperative day. RESULTS: Good hemostasis, normal healing, and no complications was shown postoperatively. CONCLUSION: The replacement of fresh frozen plasma was useful in the case of congenital clotting factor deficiency for bleeding prophylaxis in cleft palate operation.

BACKGROUND: Serious organ shortage necessitates ABO incompatible (ABOi) kidney transplantation (KT). Recent reports utilizing rituximab instead of splenectomy and tacrolimus (FK)-based triple immunosuppressants showed excellent graft outcome. METHODS AND RESULTS: Thirteen cases of ABOi living donor KT have been performed since Feb. 2007 in our center. Donor and recipient blood group was B to O (n=5), A1 to O (2), AB to B (2), AB to A1 (1), A1 to B (2) and B to A1 (1). Rituximab was given at 4 weeks before transplantation. Plasmapheresis (PP) was initiated at 7~14 days before transplantation with concurrent immunosuppressants. The number of pretransplant PP was 5.7+/-1.4. Posttransplant PP was also performed in 6 patients with higher initial titer of ABO antibody (IgG > or =256; n=2), rapidly rising antibody titer during the critical period of 2 weeks posttransplantation (n=2), or increase in serum creatinine during the critical period while awaiting pathology report of graft biopsy (n=2). Mean number of posttransplant PP in these 6 patients was 2.2+/-1.3. Median IgG anti-ABO antibody titer before precondition, at transplantation, at 2 weeks and at 6 months was 64 (8~512), 2 (1~8), 2 (1~16) and 6 (1~16), respectively. IgM titer at corresponding time point was 16 (2~128). 1 (1~1), 1 (1~2) and 1.5 (1~4), respectively. Median follow up was 8 (5~27) months. No patient or graft was lost. No patient developed acute humoral rejection. Graft function remained stable with latest serum creatinine 1.2+/-0.3 mg/dl. CONCLUSIONS: ABOi living donor KT without splenectomy can be safely performed with the use of current preconditioning and immunosuppressive regimen, and is therefore a valuable option for expanding donor pool and should be actively performed in Korea.

Leber's hereditary optic neuropathy (LHON) is an important cause of bilateral optic neuropathy in youth and occasionally associated with other neurological abnormalities (Leber's plus). The authors recently found out one family of LHON and another patient of Leber's plus with mitochondrial DNA (mtDNA) 11778 mutation. The presence of a point mutation of mtDNA was investigated by restriction length fragment polymorphism. Among 14 patients who had mtDNA 11778 mutation in the family, only two men had bilateral optic neuropathy. The other was a man of optic neuropathy with myelopathy. The age at onset of visual loss ranged from 14 to 25 (average 19.7). The time delay between involvement of the two eyes was I to 3 months Central visual field defect was observed in each of all affected eyes and worse in the earlier affected. The brain MRI and CSF studies revealed no abnormality. This study showed that the clinical manifestations and genealogical features of LHON in our patients are similar to those of previously reported cases in other countries.

PURPOSE: We wanted to evaluate the findings and diagnostic accuracy of MDCT for diagnosing occlusive acute myocardial infarction in rabbits. MATERIALS AND METHODS: Myocardial infarction was induced in 14 rabbits. MDCT was performed in the early and delay phases at 1 minute and 6 minutes, respectively, after intravenous contrast injection. The rabbits were sacrificed after scanning. The cardiac specimens were sliced and then stained with triphenyltetrazolium chloride (TTC). The agreement in the transmural extent of infarction between the MDCT scans and the TTC-stained specimens were analyzed by using kappa values. RESULTS: Acute myocardial infarction was found in 9 of 14 rabbits on the TTC-stained specimens and MDCT. The infarcted myocardium was demonstrated as a low-attenuation area on the early phase and as a central low-attenuation area with rim-like enhancement along the endocardial and pericardial sides of the myocardial wall on the delay phase. There was excellent agreement in the scores of the transmural extent of myocardial infarction between the TTC-stained specimens and the early phase scan (kappa value = 0.882, p = 0.000), and there was fair to good agreement between the TTC-stained specimens and the delay phase scan (kappa value = 0.439, p = 0.000). Microscopic examination of the cardiac specimens revealed necrosis of myocardial cells in the central portion and granulation tissue along the endocardial and pericardial sides of the necrotic myocardium. CONCLUSION: 16 slice MDCT scan was useful for the diagnosis of acute myocardial infarction. The early phase scan was more accurate than the delay phase scan for evaluating the transmural extent of myocardial infarction. Histopathologic examination suggested that the low-attenuation area on the delay phase might correspond to necrotic myocardium and the enhanced area might correspond to granulation tissue.
