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.

BACKGROUND/AIMS: The natural history of severe erosive reflux disease in Korea remains uncertain. We aimed to evaluate endoscopic follow-up results in subjects with severe reflux esophagitis under routine clinical care. MATERIALS AND METHODS: A total 61,891 subjects underwent an upper endoscopic examination in the health check-up program from January 2007 to December 2013. We reviewed medical charts of patients who had been diagnosed with severe reflux esophagitis. The severity of reflux esophagitis was determined by the Los Angeles (LA) classification system. Patients underwent at least one follow up endoscopy after diagnosis of severe reflux esophagitis. We classified the patients into two groups; regressed in severity and remained unchanged, according to follow up endoscopic status. RESULTS: Based on endoscopic findings, 5,938 subjects (9.6%) were found to have reflux esopohagitis: 121 subjects (0.2%) in LA-C; 39 subjects (0.06%) in LA-D. Among 31 patients who had endoscopic follow-up, 23 patients (74.2%) showed regression from LA C/D to LA A/B or minimal change disease or normal. The mean follow up duration was 42.2 months in regression group and 53.2 months in no change group. All patients had been treated with proton pump inhibitors (PPIs) on a regular or on-demand basis. Age, sex, smoking, alcohol, exercise, hypertension, diabetes mellitus, dyslipidemia, sliding hiatal hernia, body mass index, waist circumference and duration of PPIs therapy did not significantly influence regression of severe reflux esophagitis. CONCLUSIONS: The majority of severe reflux esophagitis patients under routine clinical care showed improvement on endoscopic follow-up.

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.

Pheochromocytoma, the catecholamine-producing tumor of chromaffin tissue, is associated with a curable form of hypertension. Recently we report the case of a 59 year-old male admitted for an acute myocardial infarction and who subsequently developed late recurrent severe ventricular arrhythmia coincident with transient hypertensive episodes. A pheochromocytoma was diagnosed on the basis of the urinary concentration of catecholamines and computerized tomography of the adrenal glands. After stabilization of his cardiac rhythm and blood pressure with alpha adrenergic blockade, the left adrenal gland, which contained the tumor, was subsequently resected. The diagnosis of a pheochromocytoma should be considered when recurrent ventricular arrhythmia are associated with intermittent hypertension after acute myocardial infarction.

PURPOSE: A multicenter study was performed to evaluate the clinical characteristics and the results of chemotherapy in patients with testicular tumor. MATERIALS AND METHODS: We retrospectively reviewed the records of 121 patients with testicular tumor treated at five university hospital between 1980 and 1997. We analyzed the clinical characteristics, additional treatments after orchiectomy and results of chemotherapy. RESULTS: Patients age ranged from 1 month to 74 years with a mean of 24 years. The common presenting symptoms were scrotal swelling in 63 patients, palpable mass in 50, and testicular pain in 12. The location of the tumor was on the right side in 62, left in 58, and both in 1 with lymphoma. The histologic type was germinal neoplasm in 101 patients, nongerminal neoplasm in 1, and other tumors in 19. Clinically, 76 patients(62.8%) were stage I, 16(13.2%) stage IIa, 12(9.9%) stage IIb, 3(2.5%) stage IIc, 9(7.4%) stage III and 5(4.1%) stage IV. After orchiectomy, 73 patients(60.3%) were underwent close observation, 30(24.8%) chemotherapy, 14(11.6%) radiation therapy, 3(2.5%) radiation plus chemotherapy and 1(0.8%) retroperitoneal lymph node dissection. Among the 33 chemotherapy patients, 12(36.4%) patients achieved a clinical complete remission(CR), 5(15.2%) partial remission(PR), 4(12.1%) minor response and stabilization, 5(15.2%) progression and 7(21.2%) patients were follow-up loss, and the overall clinical response rate was 65.4%. Among the 18 chemotherapy patients with nonseminomatous germ cell tumor(NSGCT), 9(50.0%) patients achieved a clinical CR, 4(22.2%) PR, 1(5.6%) minor response and stabilization, 2(11.1%) progression and 2(11.1%) patients were follow-up loss, and the overall clinical response rate was 81.3%. CONCLUSIONS: Our study group was relatively small and insufficient to evaluate the chemotherapeutic results, but NSGCT seems to have a better clinical response to chemotherapy.
