PURPOSE: The purpose of this study was to determine the role of CT and MR imagings in the diagnosis aortic dissection and differentiation between the true and false lumen. MATERIALS AND METHODS: We retrospectively studied forty patients with aortic dissection(AD) diagnosed imagings or surgery. Of the forty patients, 19 were examined with only CT, 14 with CT and MR, and 7 with MI~: Our points of view were(1) the classification of AD according to configuration of intimal flap by cross-sectional imaging, (2) differentiation between the true and false lumens, (3) the course of the false lumen, and (4)! detectability of the origin of major branch vessels of the abdominal aorta. RESULTS: The classification by corss-sectional imaging were crescentic(65%), circumferential(15%), flat(12%), and irregular(8%) type, in which false negative diagnosis was made in 1 case of crescentic and circumferential type, respectively. In 2 case of flat type and 1 case of irregular type, the differentiation between the true and false lumen was impossible with CT. The course of the false lumen in descending thoracic aorta revealed countrclock wise rotation(66%), clockwise rotation(5%) or fixed(29%) apperance. MR imaging was superior to CT in the detection of the origin of major branch vessels of the abdominal aorta. The determination of the origin of major branches of abdominal aorta arising from the true and false lumen were impossible in 2 cases in which only CT was done. CONCLUSION: Diagnosis of crescentic and circumferential types of AD with narrow and thrombosed false lumen was problematic in both CT and MR with no difference of diagnostic accuracy between the two modalities. The differentiation between the true and false lumen was difficult in flat and irregular types with only CT. Therefore, when surgical treatment is considered as in type B aortic dissection, MR imaging is recommended in order to determine the origin of major branch vessels.

A survey of the literature on the treatment of ruptures of deltoid ligament associated with fracture of distal part of fibula is controversial. Some authors advocated surgical repair of the ruptured deltoid ligament based on the theoretical consideration, while others advocated non-operative treatment based on the clinical consideration. We studied the results in forty-five patients who were treated for disruption of the deltoid ligament and a distal fibular fracture. The length of follow-up in our series was twelve to twenty-four months, with an average of fifteen months. When the fibular fracture was adequately reduced and medial clear space was returned to its normal width, the 91 percents both of patients of being treated with repair of deltoid ligament and patients of being treated without repair had a good or excellent results.

PURPOSE: We performed nerve-sparing robot-assisted radical cystectomy (nsRARC) and compared the operative outcomes of nsRARC and open radical cystectomy (ORC). MATERIALS AND METHODS: The data of 38 patients that underwent ORC or nsRARC for bladder cancer between July 2009 and April 2014 (23 ORC and 15 RARC) were retrospectively analyzed. Data were collected on patient demographics, pathologic stages, perioperative outcomes, and oncologic outcomes as well as on erectile function. Five-year overall survival and cancer-specific survival were analyzed using the Kaplan-Meier method. Erection function recovery was defined as the ability to achieve penetration ≥50% of the time and to maintain an erection sufficient enough for penetration ≥50% of the time at 12 months after surgery. RESULTS: No significant differences were found between the nsRARC and ORC groups in terms of age, sex, body mass index, American Society of Anesthesiologists physical status, or clinical stage. Mean estimated blood loss was significantly less in the nsRARC group (205.3 mL vs. 394 mL, p=0.011), but mean operative time was significantly greater (520.3 minutes vs. 415.0 minutes, p=0.004). Five-year overall survival and cancer-specific survival were 86.7% and 86.7%, respectively, for nsRARC, and 77.7% and 86.7% for ORC. With respect to erectile function, the overall postoperative potency rate at 12 months was 40.0% in the RARC group and 9.5% in the ORC group, and this difference was significant (p=0.021). CONCLUSIONS: Our clinical experiences indicate nsRARC in selected patients is a feasible procedure in terms of oncologic outcome and that it preserves erectile function relatively effectively.

Damage of temporomandibular joints in infancy may result in ankylosis and alteration of the mandibular growth. In case of unilateral ankylosis occurring in early childhood, a mandibular hypoplasia of the affected side usually follows. The patients have limitation of mouth opening, poor oral hygiene, facial and mandibular growth disturbances, and rarely, upper airway obstruction in the form of either night snoring or obstruction sleep apnea. The objective of this study is to show the use of distraction osteogenesis in mandibular hypoplasia associated with ankylosis and to present our technique for the treatment of mandibular hypoplasia with unilateral ankylosis in infancy consisting of simultaneous arthroplasty which treats the ankylosis and mandibular distraction and enables to correct the facial asymmetry in the same procedure. Between November 1999 and May 2000, three girl patients (42, 44, and 48 months old) who had mandibular hypoplasia associated with ankylosis were treated with simulatneous arthroplasty and distraction osteogenesis. Two kinds of arthroplasties, consisting of gap arthroplasty for one patient and interpositional arthroplasty using a temporal fascia turn-over flap for the other two patients, were executed and mandibular distraction in all three patients. Mouth-opening exercises began on the first day following the operation. Mandibular distraction began on the fifth day after the operation at a rate of 1 mm per day (0.5 mm twice a day) and continued to achieve a slight overcorrection of deviated chin. From the first day after the operation, an increase in the mouth opening was achieved. The average duration of distraction was 20 days. Average duration of consolidation was 6 weeks. Oral opening increased from 2 to 20 mm in case of the first patient, from 4 to 28 mm in the second patient, and from 5 to 24 mm in the third patient. The follow-up period was from 5 to 12 months (mean 8 months). At the time of final evaluation, oral opening and a more normal facial contour persist. It is believed that mandibular distraction combined with arthroplasty offers a new therapeutic option for the treatment of mandibular hypoplasia associated ankylosis, with minimal morbidity and complications.

BACKGROUND: The purpose of this study was to investigate the relationship between 7 health habits and health-related quality of life using the SF-36 questionnaires. METHODS: The subjects for this study were 550 workers in Seongnam City, Kyonggi Province, Korea. Data were collected by using constructed questionnaires from 11 September 2004 to 25 September 2004. Statistical analyses were conducted using SPSS. RESULTS: There were positive relationships of favorable health habits as indicated by Alameda 7 to health-related quality of life. After controlling for the effects of confounding cofactors that included age, sex, diseases, and other health habits, multiple regression analysis indicated as follows. 1) The item of 'eating breakfast everyday' were significantly related to the grade of social function (SF) and bodily pain (BP). 2) The item of 'sleeping for 7~8 hours a day' were significantly related to all domains of the SF-36 except physical function (PF). 3) The item of 'normal Body Mass Index' were significantly related to the grade of Role limitations-emotional (RE). 4. The item of 'regular physical exercise' were significantly related to the grade of general health (GH), physical function (PF), Vitality (VT), and mental health (MH). Other health habits like not snacking between meals, never smoking, and low alcohol consumption were not associated with any of the SF-36 profiles. CONCLUSION: There were positive relationships of favorable health habits to health-related quality of life. It is important to have favorable health habits for good health-related quality of life.

The association between blood lead children and Intelligent Quotient(IQ) was investigated in a sample of l00 boys and girls aged 6-8 years from one primary school within an industrial area of Pusan. The trained undergraduates in school of public health administered an I.Q. test one by one. Parents answered a questionnaire on demographic, perinatal and socioeconomic variables. Atomic Absorbtion spectrophotometer was used to determine blood lead levels. The geometric mean of blood lead value was 7.99 microgram/dl. In total children, there was no significant relationship between blood lead level and I.Q. But in the children who were born of gestational age of less than 38 weeks, children with higher levels of blood lead performed more poorly on I.Q. test with correlation coefficient from -0.68 to -0.71. But, the children who were born of gestational age of 38 weeks and more were same as total children. These results suggest that exposure to low levels of lead in the children who were born premature probably may result in impaired intelligent development. But, we think that more profound study should be performed with sufficient numbers of subjects.

Despite recent advances in the management of a wide variety of solid tumors, the outcomes for patients with advanced urothelial carcinoma remain relatively poor. Cisplatin-based combination chemotherapy remains the standard of care for first-line systemic treatment of advanced urothelial carcinoma and for more than 10 years there have been no other Korean health insurance system-approved treatment options available for these patients. In this review article, we summarize the current state of chemotherapeutic agents, used either alone or in combination with other chemotherapy in advanced urothelial carcinoma. Our discussion focuses on the new agents for the cisplatin ineligible patients, including carboplatin, gemcitabine, paclitaxel, docetaxel and pemetrexed. Moreover, we addressed that neoadjuvant chemotherapy was supported in the patients planning radical cystectomy as an optimal treatment option by qualified studies.

Tumors from patients with hereditary non-polyposis colorectal cancer (HNPCC)and from a subset of patients with the related Muir-Torre syndrome exhibit a type of a genetic instability, known as microsatellite instability (MIS), which results from mutations that inactivate DNA mismatch repair genes. Keratoacanthomas resemble squamous cell carcinoma but after a period of rapid growth over a few months they involute completely. The detection of MIS in a keratoacanthoma from a patient with Muir-Torre syndrome suggested that defective mismatch repair genes may play a role in the pathogenesis of these neoplasmas. In order to elucidate the significance of both MIS and loss of heterozygosity (LOH)in the pathogenesis of sporadic keratoacanthomas, the presents of MIS and LOH at 11 microsatellite markers (D2S286, D2S367, D3S1317, D5S346, D9S16, D9S171, D10S89, D10S185, D11S904, D17S261, and D17S520) were evaluated in randomly selected sporadic keratoacanthomas. MIS and LOH were found only in 1 of 10 cases at D17S261 and D10S185, respectively. In conclusion, the low frequency of MIS and LOH detected in this study suggests that neither MIS nor LOH appear to be significant in the induction of sporadic keratoacanthomas.
