  • Background A micro-arteriovenous fistula (AVF) is a minute, short shunt between an artery and a vein that does not pass through a capillary. We investigated the association between micro-AVFs and lymphedema using computed tomography angiography (CTA) and venous blood gas analysis. Methods In 95 patients with lower limb lymphedema, the presence or absence of early venous return (EVR) was compared between patients with primary and secondary lymphedema. Furthermore, we investigated the difference in the timing of edema onset in patients with secondary lymphedema with or without EVR using CTA. In 20 patients with lower limb lymphedema with confirmed early EVR in a unilateral lower limb, the partial pressure of oxygen (PO2) was compared between the lower limb with EVR and the contralateral lower limb. Results Secondary lymphedema with or without EVR occurred at an average of 36.0±59.3 months and 93.5±136.1 months, respectively; however, no significant difference was noted. PO2 was 57.6±11.7 mmHg and 44.1±16.4 mmHg in the EVR and non-EVR limbs, respectively, which was a significant difference (P=0.005). Conclusions EVR and venous blood gas analysis suggested the presence of micro-AVFs in patients with lower extremity edema. Further research is warranted to examine the cause of micro-AVFs, to advance technology to facilitate the confirmation of micro-AVFs by angiography, and to improve lymphedema by ligation of micro-AVFs.

  • Background There are currently no guidelines for the postoperative wound management of the hard-palate donor site in cases involving mucosal harvesting. This study describes our experiences with the use of an artificial dermis for early epithelialization and transparent plate fixation in cases involving hard-palate mucosal harvesting. Methods A transparent palatal plate was custom-fabricated using a thermoplastic resin board. After mucosal harvesting, an alginic acid-containing wound dressing (Sorbsan) was applied to the donor site, which was then covered with the plate. After confirming hemostasis, the dressing was changed to artificial dermis a few days later, and the plate was fixed to the artificial dermis. The size of the mucosal defect ranged from 8×25 to 20×40 mm. Results Plate fixation was adequate, with no postoperative slippage or infection of the artificial dermis. There was no pain at the harvest site, but a slight sense of incongruity during eating was reported. Although the fabrication and application of the palatal plate required extra steps before and after harvesting, the combination of the artificial dermis and palatal plate was found to be very useful for protecting the mucosal harvest site, and resulted in decreased pain and earlier epithelialization. Conclusions The combination of artificial dermis and a transparent palatal plate for wound management at the hard-palate mucosal donor site resolved some of the limitations of conventional methods.

  • Objective: We aimed to propose a set of quality indicators (QIs) based on the clinical guidelines for cervical cancer treatment published by The Japan Society of Gynecologic Oncology, and to assess adherence to standard-of-care as an index of the quality of care for cervical cancer in Japan. Methods: A panel of clinical experts devised the QIs using a modified Delphi method. Adherence to each QI was evaluated using data from a hospital-based cancer registry of patients diagnosed in 2013, and linked with insurance claims data, between October 1, 2012, and December 31, 2014. All patients who received first-line treatment at the participating facility were included. The QI scores were communicated to participating hospitals, and additional data about the reasons for non-adherence were collected. Results: In total, 297 hospitals participated, and the care provided to 15,163 cervical cancer patients was examined using 10 measurable QIs. The adherence rate ranged from 50.0% for 'cystoscope or proctoscope for stage IVA' to 98.8% for 'chemotherapy using platinum for stage IVB'. Despite the variation in care, hospitals reported clinically valid reasons for more than half of the non-adherent cases. Clinically valid reasons accounted for 75%, 90.9%, 73.4%, 44.5%, and 88.1% of presented non-adherent cases respectively. Conclusion: Our study revealed variations in pattern of care as well as an adherence to standards-of-care across Japan. Further assessment of the causes of variation and non-adherence can help identify areas where improvements are needed in patient care.

  • Objective: To elucidate the use of radiological studies, including nuclear medicine, and biopsy for the diagnosis and staging of prostate cancer (PCA) in clinical practice and understand the current status of PCA in Asian countries via an international survey. Materials and Methods: The Asian Prostate Imaging Working Group designed a survey questionnaire with four domains focused on prostate magnetic resonance imaging (MRI), other prostate imaging, prostate biopsy, and PCA backgrounds. The questionnaire was sent to 111 members of professional affiliations in Korea, Japan, Singapore, and Taiwan who were representatives of their working hospitals, and their responses were analyzed. Results: This survey had a response rate of 97.3% (108/111). The rates of using 3T scanners, antispasmodic agents, laxative drugs, and prostate imaging-reporting and data system reporting for prostate MRI were 21.6%-78.9%, 22.2%-84.2%, 2.3%-26.3%, and 59.5%-100%, respectively. Respondents reported using the highest b-values of 800-2000 sec/mm2 and fields of view of 9-30 cm. The prostate MRI examinations per month ranged from 1 to 600, and they were most commonly indicated for biopsy-naïve patients suspected of PCA in Japan and Singapore and staging of proven PCA in Korea and Taiwan. The most commonly used radiotracers for prostate positron emission tomography are prostate-specific membrane antigen in Singapore and fluorodeoxyglucose in three other countries. The most common timing for prostate MRI was before biopsy (29.9%). Prostate-targeted biopsies were performed in 63.8% of hospitals, usually by MRI-ultrasound fusion approach. The most common presentation was localized PCA in all four countries, and it was usually treated with radical prostatectomy. Conclusion: This survey showed the diverse technical details and the availability of imaging and biopsy in the evaluation of PCA. This suggests the need for an educational program for Asian radiologists to promote standardized evidence-based imaging approaches for the diagnosis and staging of PCA.

  • 이 연구는 GIS가 UIS로 발전하는 과정을 분석하고 UIS의 발전방향을 제시하고자 한다. 연구방법으로는 GIS를 유형화하고 유형별로 대표적인 사례도시를 선택하는 사례분석을 활용하였다. 연구범위로는 기초자치단체의 UIS를 유형별로 (1) 지하시설물관리 중심으로 발전한 UIS(경기도 과천시), (2) 도시계획관리를 중심으로 발전한 UIS(충청북도 청주시), (3) 토지정보시스템을 중심으로 한 UIS(대구광역시 남구청)에 한정하였다. GIS에서 UIS로 발전한 사례분석의 결과를 종합하면, 첫째, 선도적인 UIS의 발전과정은 단편적 접근단계에서 통합적 접근단계를 거쳐 인터넷 GIS로 발전하고 있다. 둘째, GIS는 각 도시의 필요에 따라 GIS가 구축되었던 것과 유사하게 UIS의 전개과정도 실무자의 필요성 인식에서 시작한 사례와 중앙정부의 재정지원으로 이루어진 사례로 나누어지고 있다. 셋째, 지방자치단체들이 UIS의 구축에서 비용이 많이 들어가지만 중앙정부로부터 예산확보가 용이한 지하시설물관리에 초점을 두는 경향이 있다. 이 연구는 UIS의 유형별 평가를 토대로 유형별로 정책제안을 하고 있다.

  • Introduction: Mammography is the most basic modality in breast cancer imaging. However, the overlap of breast tissue depicted on conventional two-dimensional mammography (2DMMG) may create significant obstacles to detecting abnormalities, especially in dense or heterogeneously dense breasts. In three-dimensional digital breast tomosynthesis (3DBT), tomographic images of the breast are reconstructed from multiple projections acquired at different angles. It has reported that this technology allows the generation of 3D data, therefore overcoming the limitations of conventional 2DMMG for Western women. We assessed the detectability of lesions by conventional 2DMMG and 3DBT in diagnosis of breast cancer for Japanese women. Methods: The subjects were 195 breasts of 99 patients (median age of 48 years, range 34~82 years) that had been pathologically diagnosed with breast cancer from December 20, 2010 through March 31, 2011. Both conventional 2DMMG and 3DBT imaging were performed for all patients. Detectability of lesions was assessed based on differences in category class. Results: Of the affected breasts, 77 (75.5%) had lesions assigned to the same categories by 2DMMG and 3DBT. For 24 (23.5%) lesions, the category increased in 3DBT indicating improvement in diagnostic performance compared to 2DMMG. 3DBT improved diagnostic sensitivity for patients with mass, focal asymmetric density (FAD), and architectural distortion. However, 3DBT was not statistically superior in diagnosis of the presence or absence of calcification. Conclusions: In this study, 3DBT was superior in diagnosing lesions in form of mass, FAD, and/or architectural distortion. 3DBT is a novel technique that may provide a breakthrough in solving the difficulties of diagnosis caused by parenchyma overlap for Japanese women.

  • Objectives This study was performed to compare responses of Korean to the Sasang Constitution questionnaire with those of Japanese and to learn difference in characteristic according to the Sasang Constitution between two countries. Methods 301 Korean visiting the department of the Sasang Constitution, Dong-Eui Medical Center in Busan, Korea from November 2006 to September 2010 responded to the SSCQ-P(Sasang Constitution Questionnaire for Patients). Sasang Constitution specialist interviewed subjects and diagnosed their Sasang Constitution. 361 Japanese visiting the center for Kampo Medicine, Keio University in Tokyo, Japan from January 2010 to February 2011 responded the SSCQ-J(Sasang Constitution Questionnaire for Japanese). The Sasang Constitution was diagnosed in the same way as Korean. We compare responses to the SSCQ-P in Korean with those to the SSCQ-J in Japanese. Results 1. Among Soyangin related 58 items of Sasang Constitution questionnaire, 26, 46.36% items had statistically significant response results in both Korean and Japanese and response disposition of all these items was same. Among Taeeumin related 68items, 36, 52.94% items had statistically significant response results in both Korean and Japanese. Of these, response disposition of 35 items was same and that of 1 item was different. Among Soeumin related 71 items, 31, 43.66% items had statistically significant response results in both Korean and Japanese. Of these, response disposition of 28 items was same and that of 3 items was different. 2. The proportion of items having statistical significance and same disposition in both Korean and Japanese by Sasang Constitutional characteristic category[Features and Way of Speaking, Physical Appearance, Temperament and Talent, Pathological Syndromes] was as follows; In Soyangin, the proportion in Pathological Syndromes was 27.8% and that in the others was more than 41.7%. In Taeeumin, the proportion in Pathological Syndromes was 33.3% and that in the others was more than 57.9%. In Soeumin, the proportion in Features and Way of Speaking was 70.6%, that in Physical Appearance was 8.3% and that in the others was 30~40%. Conclusions The response disposition of many of items having statistical significance between Korean and Japanese was same and that of a few was different. From this, there are many common Sasang Constitutional characteristics between two countries, and possibility of applying the Sasang Constitutional Medicine of Korea to Japan.
