In 1971 inclusion body myositis was reported by Yunis and Samaha. This disease is similar with chronic multiple myositis clinically. Pathologically, inclusion body myositis is characterized by intracytoplasmic vacuole with degenerating fibers and accompanied with inclusion body in internal nucleus and cytoplasm. Since then 240 cases of inclusion body myositis have been reported in the world including 3 cases in Korea. A 27 years-old lady had inclusion body myositis, which show slowly progressive muscular weakness. We confirmed this with clinical symptom, muscle biopsy, and electrophysiologic study. We report the typical manifestation of inclusion body myositis in a 27 years-old lady with the brief review of literature.

The physical activity has an important physiological and psychological benefit for all people, and the exercise program has a key role in the management of diabetes. This article presents exercise recommendations for people with diabetes. Though the patients with diabetes may give many benefits from regular physical exercise, there may be several hazards from exercise as well. We assessed 30 patients with type 2 Diabetes Mellitus and 15 normal control subjects with sedentary life-style for their workload, heart rate on maximal performance and maximal oxygen uptake, change of blood glucose level after exercise using bicycle ergometer and Astrand nomogram. The workload, heart rate on maximal performance and maximal oxygen uptake were lower in diabetic patient than control subjects. Blood glucose decreased in diabetic patient than control subjects, after exercise and the lowered value was maintained until 60 minutes after exercise. The maximal oxygen uptake was lower in diabetic patients than control subjects. The blood glucose decreased in both diabetic patients and normal control after exercise.

A 40-year-old female patient who had tethered spinal cord with intraspinal lipoma and intractable pain of the lower leg and foot is reported. The pain started 5 years ago and exaggerated recently. A pea-size mass had been noted since birth at sacral region, which was excised 2 months prior to admission at the other clinic. Neurological examination revealed diffuse muscular wasting of the left foot, especially the sole, hypesthesia of the left sole with dysesthesia, bilaterally increased knee jerks, and absent left ankle jerk. The patient underwent L5 laminectomy, subtotal removal of extradural, intradural and intramedually lipoma with dural repair, and dorsal rhizotomy of ipsilateral L5 and S1 roots. At surgery, the neural elements were untethered with mass removal, adhesiolysis, and division of thickened arachnoid septum. The pain improved much after and was tolerable with some analgesics.

OBJECTIVE: The contents of microbial information are complicated because of being hierarchical, duplicated as well as their changes are continuous and various. Much of time and cost are required for maintaining, expanding the information after representing them into a relational database. The relational database is not adequate to make the information sharable via Internet. In addition, user's meta-knowledge is insufficient to use the information via Internet and users may not be able to cope with the continuous changes of microbial information through the static web interface. Therefor, this study is conducted to develop an active microbial web database for resolving those problems. METHODS: To solve these problems, object-oriented database, which was able to represent the complicated contents and knowledge, was used, and intelligent agents were implemented to cope with the continuous evolution of microbial information. Also, they were incorporated into user interface to assist users in an interactive environment, who want to use information via Internet. RESULTS: The implemented system have shown advantages of solving difficulties arising from hierarchical and duplicated microbial data. It showed the possibility to share and manage the complex microbial data via Internet. It helped the system to be implemented as the active database, information stored in the object-oriented database. CONCLUSION: This study indicates that a similar approach may lead to develop an expert system based on the web and active database, which is able to be evolved, and to develop intelligent interface, using the agent.

In 1965 Gillespie reported a new syndrome of bilateral aniridia, cerebellar ataxia, and oligophrenia (mental retardation). This new syndrome was named Gillespie syndrome. Since then only 17 cases of Gillespie syndrome have been reported in UK, Brazil, Ireland, Belgium, Australia, and US. A case of Gillespie syndrome was not reported in Korea. A 4 year-old girl has triad of Gillespie syndrome, which are partial aniridia, cerebellar ataxia and mental retardation. We confirmed this with ophthalmologic examination, brain MRI, and developmental delay. We report the typical manifestation of Gillespie syndrome in a 4 year-old girl with the brief review of literature.

PURPOSE: Although transarterial chemoembolization (TACE) has been widely used for the treatment of unresectable hepatocellular carcinoma, it has not been determined yet which chemotherapeutic agents were best for TACE. To determine the best chemotherapeutic regimen for TACE, we performed a prospective randomized study comparing 3 chemo- therapeutic regimen (adriamycin alone vs. cisplatin alone vs. adriamycin + cisplatin). MATERIALS AND METHODS: The patients with unresectable hepatocellular carcinoma were eligible for this study and were randomly assigned to three treatment groups (A: adriamycin 30 mg/m(2), B: cisplatin 60 mg/m(2), C: adriamycin 30 mg/m(2) + cisplatin 60 mg/m(2)). The TACE were performed by administering the mixture of lipiodol and the assigned chemotherapeutic drugs through the hepatic artery, followed by embolization with gelfoam powder. The treatment was planned to be repeated every 4 weeks. RESULTS: After 40 patients (14 in group A, 16 in group B, 10 in group C) entered, the study was stopped prematurely because of serious treatment-related complications including 15% of local complications, 18% of hepatic encephalopathy, and 8% of deaths. Because TACE could result in necrosis without reduction of mass size, the response could not be evaluated by the change of mass size, but by the change of serum alpha-fetoprotein level. Of 25 patients who had elevated serum alpha-fetoprotein and were assessable for response, there were one complete response (CR) and 5 partial responses (PR) out of 10 in group A, 5 PRs out of 10 in group B, and 2 PRs out of 5 in group C. There was no difference in response rates among the 3 treatment groups (p > 0.05). The response rate in patients treated with gelform embolization was higher than patients without embolization (63% (12/19) vs 19% (1/6): p<0.05). The median survival (OS) was 23 weeks for all 40 patients, 15 weeks for group A, 42 weeks for group B and 24 weeks for group C. The difference of OS between group A and B was statistically significant (p=0.02). However, the OS was not associated with any prognostic factors including treatment group in multivariate analysis. CONCLUSION: Although cisplatin seemed to be more effective in TACE than adriamycin, no firm conclusion could be drawn from this prematurely ended study. However, we could conclude that the TACE with gelform powder is so toxic that it could not be given safely to the patients with unresectable hepatocellular carcinoma

PURPOSE: This study was conducted to explore the process and operation of a cancer multidisciplinary team (MDT) after the reimbursement decision in Korea, and to identify ways to overcome the major barriers to effective and sustainable MDTs. MATERIALS AND METHODS: Approximately 1,000 cancer specialists, including medical oncologists, surgical oncologists, radiation oncologists, pathologists, and radiologists in general hospitals in Koreawere invited to complete the survey. The questionnaire covered the following topics: organizational structure of MDTs, candidates for consulting, the clinical decision-making initiative, and responsibility for dealing with legal disputes. RESULTS: We collected a total of 179 responses (18%) from physicians at institutions where an MDT approach was active. A surgical oncologist (91%), internist (90%),radiologist (89%),radiation oncologist (86%), pathologist (71%), and trainees (20%) regularly participated in MDT operations. Approximately 55% of respondents stated that MDTs met regularly. In cases of a split opinion, the physician in charge (69%) or chairperson (17%) made the final decision, and most (86%) stated they followed the final decision. About 15% and 32% of respondents were “very satisfied” and “satisfied,” respectively, with the current MDT's operations. Among 38 institutional representatives, 34% responded that the MDT operation became more active and 18% stated an MDT was newly implemented after the reimbursement decision. CONCLUSION: The reimbursement decision invigorated MDT operations in almost half of eligible hospitals. Dissatisfaction regarding current MDTs was over 50%, and the high discordance rates regarding risk sharing suggest that it is necessary to revise the current system of MDTs.

Many predictive models have been proposed for better stratification of diffuse large B-cell lymphoma (DLBCL). Hans' algorithm has been widely used as standard to sub-classify DLBCL into germinal center B-cell (GCB) and non-GCB origins. However, there have been disagreements in the literature regarding its prognostic significance. Here, we retrospectively analyzed Hans' algorithm and the individual immunohistochemical biomarkers at different cut-off values (5%, 30%, 50% or 75%) in 94 Korean patients with DLBCL treated with combination chemotherapy with cyclophosphamide, daunorubicin, vincristine, and prednisone. No significant differences were observed between the GCB (18 patients, 19.1%) and non-GCB (76, 80.9%) groups. Among individual biomarkers, CD10 negativity (cut point: 30%) and bcl-6 positivity (cut point: 5%) were independent good prognostic markers in progression-free survival (PFS), whereas bcl-6 (cut point: 5%) positivity was an independent good prognostic marker in overall survival irrelevant of international prognostic index. The present study showed the lack of predictability of Hans' algorithm in DLBCL patients, and that CD10, Bcl-6 may have diverse prognostic significance at different cut-off values. Our results suggest that the proposed cut-off value may not be applied universally, and that the optimal cut-off value may need to be optimized for individual laboratory.

Patient expectations for specialized medical care have spawned fellowship programs that require additional subspecialty training after residency training completion. The present study assessed the curricula and training environment adequacy of fellowship programs as perceived by current trainees and identified improvement areas for South Korea's overall fellowship program. A questionnaire was distributed to 1,764 fellows training at 6 university hospitals in Seoul, Korea during October 2014. From a return rate of 33.1%, 26.2% (403 responses) of all questionnaires distributed were compete enough to include in the analysis. Fellows participating in the survey were enrolled in fellowship programs with occupational aspirations of professorship and academic aspirations of subspecialty exploration. Nevertheless, more than half of the participating fellows did not have a clear understanding of their program's objectives. Many hoped for reduced clinical hours, increased research time allowance, and higher pay compared to current training environment and salary. The fellows' satisfaction with their program's curriculum and training environment was above 3 points on a Likert scale of 1 to 5. Receiving a training objective and financial support for academic activities by the training institution were factors influencing fellows' satisfaction level regarding both the curriculum and training environment. Clearly defined program objectives, a specialized curriculum for fellows, improved working conditions, and reflection on medical workforce policies are imperative for the advancement of Korean fellowship programs.
