Congenital renal arteriovenous fistula is a rare disease and manifested by gross hematuria, bladder tamponade and flank pain. We experienced one case of congenital renal arteriovenous firstula which was cirsoid type and treated with superselective transcatheter arterial embolization of four small segmental arteries. The microcoils made of platinum and synthetic fiber were used as theembolization modality.

Carcinoma of lung is classified by histologic cell type, this is based on predominant major cell population by tissue specimen. But in fact a range of 13% to 63% of lung cancer has been appeared to be heterogeneous cell type at the light microscopic level. After treatment of the mixed lung cancer and/or with time there are reports that cell type is changed. Because it is possible that the tumor were pleomorphic and that the antitumor therapy eliminated the more sensitive cell population and permitted the subsequent emergence of the more resistant cell population. The authors reported here, a case of 32 year old female patient with mixed lung cancer composed of three cell type, and this is the first case in Korea.

BACKGROUND: In contrast with bone formation markers, most of available indices of bone resorption are urine markers and show relatively high degree of variability. The serum resorption assay has therefore been developed. We evaluated serum bone-derived degradation products of type I collagen C-telopeptide (s-CTX) and serum osteocalcin by Elecsys 2010 (Hitachi Boehringer Mannheim, Tokyo, Japan). METHODS: For 18 healthy controls, 15 osteopenic and 7 osteoporotic patients samples, serum CTX and serum osteocalcin were measured by Elecsys 2010 using -CrossLaps/serum (Roche Diagnostic Corp., Indianapolis, USA) kit and N-MID Osteocalcin (Roche Diagnostic Corp. kit, respectively. DPD by Immulite (Diagnostic Products Corp., LA, USA) using Pyrilinks-D(TM) (Diagnostic Products Corp.) kit and serum osteocalcin for correlation by Gamma counter (Hewlett Packard, Meriden, USA) using ELSA-OSTEO (CIS, Cedex, France) kit were measured. RESULTS: The within-run and between-run coefficient of variation (CV) values of s-CTX were 6.41% and 6% in low concentrations and 3.84% and 7% in high concentrations, respectively. The within-run and between-run CV values of serum osteocalcin were 2.21% and 6% in low concentrations and 1.25% and 3% in high concentrations, respectively. The dilution recovery of s-CTX and serum osteocalcin was 100-169% (mean, 134%) and 80-138% (mean, 104%), respectively. S-CTX and DPD (R=0.369, P=0.019), and serum osteocalcin by Elecsys 2010 and RIA (R=0.889, P<0.001) showed positive correlations, respectively. CONCLUSTIONS: S-CTX and serum osteocalcin by Elecsys 2010 exhibits good analytical performance and correlate with DPD and serum osteocalcin by RIA, respectively. Therefore, these may replace DPD and serum osteocalcin by RIA and can be used for bone resorption and formation markers, respectively.

A solitary fibrous tumor (STF) is a relatively unusual neoplasm first described as a distinctive tumor arising from pleura. Some reports have shown that STF also affect extrathoracic regions. A 70-year-old woman was referred to our hospital for surgical treatment of an incidentally discovered thigh mass. We performed complete removal of the tumor. It was a soft tissue tumor with muscle indentation but without invasion to the surrounding muscles. The resected specimen was 7.0x6.3x5.2 cm. Histologically, the tumor was composed of a haphazard proliferation of spindle cells and epitheloid cells with hypercellularity and high mitotic activity. Immunohistochemistry showed positive immunoreactivity for CD34, CD99, bcl-2 protein, CD117, vimentin, smooth muscle actin and epithelial membrane antigen. We report, herein, on a rare case of malignant SFT in the thigh region along with a review of the literature.

OBJECTIVE: This study was performed to evaluate relationship of burdened work and musculoskeletal symptoms in small-to-medium sized enterprises. METHOD: After a questionnaire survey was administered to 9,950 workers in 122 workplace, 7,626 workers(76.6%) were finally selected for the study analysis. Industrial hygienists visited 122 small-to-medium sized enterprises to investigate the presence of burdened works within the workplace. The selection of jobs with significant burden was based on the Ministry of Labor's recent notification in 11 types of job description associated with musculoskeletal disorders. The subjects of this study were then divided into three categories. 1) non-burdened white collar workers, 2) non-burdened blue collar workers, and 3) burdened workers (include some VDT workers). Multiple logistic regression was used to evaluate the relationship between burdened work and musculoskeletal symptoms. RESULTS: The burdened workers reported significantly more musculoskeletal symptoms than non-burdened white collar workers and non-burdened blue collar workers(OR:1.57, 95% CI: 1.314-1.875). There was no significant difference in reports of musculoskeletal symptoms between non-burdened white and blue collar workers. CONCLUSION: To prevent or diminish musculoskeletal disorders in small-to-medium sized enterprises, we need to better manage burdened works.

Nesidiodysplasia encompasses increased, maldistributed, and/or, improperly regulated or programmed endocrine cells associated with a clinical endocrine dysfunction. It is a frequent cause of hyperinsulinemic hypoglycemia in neonates and infants, but rare in adults. A 63 year-old woman was admitted due to the loss of consciousness and intense sweating. Hyperinsulinemic hypogiycemia was diagnosed. Under the presumptive diagnosis of insulinoma, abdominal ultrasonography and CT scan were done, but no definite tumor was found. Only a suspicious gradient in insulin concentration was found around the body of the pancreas by percutaneous portal venous sampling. While an exploratory laparotomy was performed, an intraoperative sonography was done. As a result, cystic mass like lesion was found. Then mass enucleation was done. Pathologic examination of the enucleated pancreas revealed no mass and the characteristic nesidiodysplasia. However, after the operation, hypoglycemic symptoms were repeated. So we are instructing her to eat meals frequently.

BACKGROUND AND OBJECTIVES: Anterolateral thigh flap (ALTF) has been reported to be very versatile and reliable for the head and neck reconstruction. The great concern in its operative technique is the anatomic variation of the perforators of the flap. The aim of study is to present our clinical experience using ALTF for the reconstruction of head and neck defects and to describe the anatomic variations of perforators among Korean patients. SUBJECTS AND METHOD: A retrospective study was conducted on patients who underwent ALTF reconstruction for their head and neck defects between April 2002 and April 2004. A total of 13 subjects (M: F=11: 2, mean age: 62 years) were considered for reconstruction after a wide surgical ablation of malignant tumors of the head and neck. The authors analyzed several items such as success rate, associated complications, characteristics of the flap, and morbidity of the donor site. RESULTS: All flaps were successfully transferred without any intraoperative complications. Partial necrosis occurred in 2 of 13 subjects, which were managed with conservative debridement and/or skin graft. As for vascular pedicles, musculocutaneous perforators from the descending branch of lateral circumflex femoral artery (LCFA) were found in 84.6% (11 of 13). In two cases (15.4%), the septocutaneous perforator from the descending branch of LCFA was the dominant supplier. The size of ALTF ranged from 8.0 to 16.0 cm in length, 4.0 to 8.0 cm in width, and 0.4 to 1.2 cm in thickness. Donor site complications were acceptable in all patients. CONCLUSION: Various types of head and neck defects were effectively managed with ALTF. We could overcome the anatomic variation of the perforators and most flaps were transferred without major complications and donor site morbidity. Further study on the anatomy of pedicles and refinements of surgical technique may make ALTF the workhorse of head and neck reconstruction.

Purpose: The association between reactogenicity and immunogenicity of the ChAdOx1 nCOV-19 is controversial. We aimed to evaluate this association among South Korean healthcare workers (HCWs). Materials and Methods: Participants received two doses of the ChAdOx1vaccine 12 weeks apart. Blood samples were tested for anti-severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) spike protein receptor binding domain antibodies about 2 months after the first and second doses using the Elecsys Anti-SARS-CoV-2 S assay kits. Adverse events were noted using an online self-reporting questionnaire. Results: Among the 232 HCWs, pain (85.78% after the first dose vs. 58.62% after the second dose, p<0.001) was the most prominent local reaction, and myalgia or fatigue (84.05% vs. 53.02%, p<0.001) was the most prominent systemic reaction. The frequency of all adverse events was significantly reduced after the second dose. After the first dose, the anti-SARS-CoV-2 S showed significantly higher titer in the group with swelling, itching, fever, and nausea. Also, the anti-SARS-CoV-2 S titer significantly increased as the grade of fever (p=0.007) and duration of fever (p=0.026) increased; however, there was no significant correlation between immunogenicity and adverse event after the second dose. The group with pain after the first dose showed a greater increase in the anti-SARSCoV-2 S difference between the second and first doses compared to the group without pain (542.2 U/mL vs. 363.8 U/mL, p=0.037). Conclusion The frequency of adverse events occurring after the first dose of the ChAdOx1 was significantly reduced after the second dose. Interestingly, the elevation of anti-SARS-CoV-2 S titer was significantly increased in the group with pain after the first dose.
