Purpose: Digital mucoid cysts are frequently found at the distal interphalangeal (DIP) joint in patients with degenerative osteoarthritis. In complicated cases, surgical treatment with mucoid cyst resection is considered, and soft tissue is covered with one of various local flap techniques. Among these, bilobed flaps are reliable and aesthetically favorable, with primary healing of the donor site. In this study, we investigated a case series of bilobed flaps for digital mucoid cysts. Methods: We retrospectively reviewed our electronic medical records and found 26 digital mucoid cysts treated with bilobed flaps at our facility between July 2022 and February 2024. We extracted data from the records of these patients on sex; age; time to surgery; clinical findings including nail ridging, the presence of osteophytes, cyst size and location, and additional procedures (arthrodesis); and follow-up data including the occurrence of complications, such as delayed wound healing, infection, stiffness, and recurrence. Results: Among the 26 patients in our sample, 19 were female and seven were male. The average age was 62.2 years, and the average time to surgery was 10.8 months. Preoperatively, the average cyst measured 6.9×8.3 mm. Nail ridging was found in 19 patients (73.1%) and osteophytes in 22 patients (84.6%). The most commonly affected digit was the middle finger, which accounted for 10 cases (38.5%). All the flaps totally survived, without major complications. Conclusion Based on our series, a bilobed flap for soft tissue coverage after mucoid cyst excision can achieve high-quality surgical results.

BACKGROUND: Pleural drainage following video-assisted thoracic surgery has traditionally been achieved with large- bore, semi-rigid chest tubes. Recent trends in thoracic surgery have been toward less invasive approaches for a variety of diseases. The purpose of this study was to evaluate the safety and efficacy of drainage by means of small, soft, and flexible 14Fr Blake drains. MATERIAL AND METHOD: Between December 2007 and March 2008, 14Fr silastic Blake drains were used for drainage of the pleural cavity in 37 patients who underwent a variety of video- assisted thoracic surgical procedures at our institution. RESULT: The average postoperative length of hospital stay was 3.26 days (range, 2~12 days), Blake drains were left in the pleural space for an average of 3.15 days (range, 1~7 days), and the average amount of drainage was 43.8 ml/day. The maximal amount of blood removed daily by a Brake drain was as much as 290 mL. There were no drain-related complications. Blake drains seemed to cause less pain while in place, and particularly at the time of removal. CONCLUSION: The use of a Blake drain following minor thoracic surgery appeared to be safe and effective in drainage of fluid or air in the pleural space, and were associated with minimal discomfort.

BACKGROUND: We investigated the effects of the common polymorphisms in the peroxisome proliferator- activated receptor gamma2 (PPAR-gamma2 Pro12Ala) and in PPAR-gamma coactivator 1alpha (PGC-1alpha Gly482Ser) genes on the association with the nephropathy of Korean patients with type 2 diabetes mellitus. METHODS: A total of 113 patients with type 2 diabetes and 123 patients with diabetic nephropathy were enrolled in this study. The Pro12Ala polymorphism of the PPAR-gamma2 gene and the Gly482Ser polymorphism in the PGC-1alpha gene were determined with the polymerase chain reaction amplification, BstU-I and Msp I enzyme digestion, and gel electrophoresis. RESULTS: The genotype and allelic frequency of PPAR-gamma2 Pro12Ala gene were not different statistically between the diabetic nephropathy and the control. The genotype of PGC-1alpha Gly482Ser in diabetic nephropathy was also not different from those in control. The allelic frequency and carriage rate of Ser allele in PGC-1alpha Gly482Ser were significantly higher in patients with diabetic nephropathy than those in control (respectively, p<0.05). CONCLUSION: The polymorphisms of the PGC-1alpha Gly482Ser gene are significantly associated with the nephropathy in Korean patients with type 2 diabetes mellitus.

BACKGROUND: The cytopathic effects of cytomegalovirus (CMV) infection have been well described since the virus was first reported; however, the morphology of CMV infection has not been clearly studied. We examined the difference in detailed cytologic findings in bronchial washing cytology between liquid-based and conventionally prepared smears. METHODS: Bronchial washing cytology was processed using either the conventional preparation (CP) or liquid-based preparation (LBP). Sixty-nine cells with typical cytopathic effects of CMV infection were detected on CP slides and 18 cells on LBP slides. Using the image analyzer, area, circumference, major axis, and minor axis of the cytoplasm, nucleus, and intranuclear inclusion were measured in singly scattered CMV-infected cells, and histiocytes were used as a control. RESULTS: The mean cytoplasmic area of CMV-infected cells was 1.47 times larger than that of histiocytes in CP and 2.92 times larger in LBP (p<.05). The mean nuclear area of CMV-infected cells was 2.61 times larger than that of histiocytes in CP and 4.25 times larger in LBP (p<.05). The nucleus to cytoplasm ratio and intranuclear inclusion to cytoplasm ratio of the mean area, circumference, major axis, and minor axis in CP were larger than those in LBP (p<.05). CONCLUSIONS: The sizes of cytoplasm, nucleus, and intranuclear inclusion were larger in LBP than in CP, indicating that CMV-infected cells are easily detectable in LBP. However, the nucleus-to-cytoplasm ratio was larger in CP, suggesting that differentiation from malignancy or regenerative atypia requires caution in CP.

In the Visible Korean project, 642 three-dimensional (3D) surface models have been built from the sectioned images of a male cadaver. It was recently discovered that popular PDF file enables users to approach the numerous surface models conveniently on Adobe Reader. Purpose of this study was to present a PDF file including systematized surface models of human body as the beneficial contents. To achieve the purpose, fitting software packages were employed in accordance with the procedures. Two-dimensional (2D) surface models including the original sectioned images were embedded into the 3D surface models. The surface models were categorized into systems and then groups. The adjusted surface models were inserted to a PDF file, where relevant multimedia data were added. The finalized PDF file containing comprehensive data of a whole body could be explored in varying manners. The PDF file, downloadable freely from the homepage (http://anatomy.co.kr), is expected to be used as a satisfactory self-learning tool of anatomy. Raw data of the surface models can be extracted from the PDF file and employed for various simulations for clinical practice. The technique to organize the surface models will be applied to manufacture of other PDF files containing various multimedia contents.

Multiple primary lung cancer is classified into a synchronous primary lung cancer or a metachronous primary lung cancer. Both are rarely encountered disease entities. We report our surgical experience of each one case of synchronous and metachronous primary lung cancer.
