A vascular necrosis of the talus has frequently been reported following trauma because talus has no muscle insertions, sixty percent of the surface of the talus is covered by hyaline cartilage, takes only a small area for entrance of a blood supply. Osteonecrosis is also associated with a variety of nontraumatic disorders. There are many indications for steroid usage, patient with rheumatoid arthritis, systemic lupus erythematosus, chronic obstructive pulmonary disease, and status- post renal or cardiac transplantation may be on long- term steroid usage, osteonecrosis may develop. A vascular necrosis of the talus secondary to chronic steroid usage is an unusual case. Delay in detection of osteonecrosis may lead to fragmentation and collapse of the talar body. When pain on range of motion is present and conservative treatment have been exhausted, surgical treatment is indicated, that is, fusion of the ankle joint. However it is important that conservative treatment may prevent its various sequelae with early diagnosis because steroid - treated patients have a more operative risk and increased risk for postoperative infection. We report a rare case of corticosteroid induced avascular necrosis of talus after cardiac transplantation.

Lenvatinib, an oral multi-kinase inhibitor, is a valuable treatment option for advanced differentiated thyroid carcinoma. However, severe treatment-related adverse events occur up to 30% of the patients receiving lenvatinib, making it a challenge for clinicians to maintain this drug and therefore affecting the outcome of therapy. Blood vessel related events, such as hypertension or proteinuria, are among the most frequent adverse events. We present a case of 65-year-old man with radioactive iodine refractory papillary thyroid carcinoma with cervical lymph node metastasis and tracheal invasion receiving lenvatinib who developed proteinuria and worsening of hypertension. Management with repeated dose reductions and using supportive medications allowed this patient to continue lenvatinib with his disease stably controlled. Early detection of patients at risk for these adverse events and cautious administration of lenvatinib at appropriate level are crucial in managing patients receiving lenvatinib.

Purpose: This study has aimed to examine the relationship among self-esteem, Activities of Daily Living (ADL) and depression reported by hospitalized elderly patients with chronic diseases. Methods: A descriptive correlation study by means of a self-report questionnaire or face-to-face interview was used to collect data from 119 elderly patients who were hospitalized in a General Hospital from January 5 to February 25, 2010. Their levels of depression was measured using Short-Form Geriatric Depression Scale, self esteem using Jeon's, and activities of daily living using K-ADL. Results: 80.7% of the subjects experienced depression. Depression correlates with self-esteem (r=-.67) and ADL (r=.45). The influencing factors on depression were self-esteem, ADL, subjective health status, and family support satisfaction ($R^2=.57$), while self esteem in itself explained 45% of variance in depression. Conclusion: These findings indicate the importance of early detection of depression, which starts from the admission of patients and the continuing evaluation/management in daily life after discharge to ensure their well-being and quality of life. The development of program empowering self esteem, ADL and subjective health status with adequate family support during hospitalization and in daily life is indispensible.

Nevus lipomatosus superficialis (NLS) is a hamartoma of adipose tissue, rarely reported in the past 100 years. We treated one case, and we conducted a systematic review of the literature. A 41-year-old man presented with a cutaneous multinodular lesion in the posterior region near the right auricle. The lesion was excised and examined histopathologically. To review the literature, we searched PubMed with the keyword "NLS." The search was limited to articles written in English and whose full text was available. We analyzed the following data: year of report, nation of corresponding author, sex of patient, age at onset, duration of disease, location of lesion, type of lesion, associated symptoms, pathological findings, and treatment. Of 158 relevant articles in PubMed, 112 fulfilled our inclusion criteria; these referred to a total of 149 cases (cases with insufficient clinical information were excluded). In rare cases, the diagnosis of NLS was confirmed when the lesion coexisted with sebaceous trichofolliculoma and Demodex infestation. Clinical awareness for NLS has increased recently. NLS is an indolent and asymptomatic benign neoplasm that may exhibit malignant behavior in terms of huge lesion size and specific anatomical location. Early detection and curative treatment should be promoted.

Along with a development of medical technology, a variety of tests, such as laboratory tests, x-ray and endoscopies are being used in health screening tests. As the tests determine the quality of health screening, test items and methods should be carefully selected. This study was to get hold of the test items of major health screening programs in Korea Most of the health screening programmes focused upon detection of risk factors and diagnosis of life - style related diseases (diabetes, hypertension, cardiovascular diseases, hypercholesterolemia, overweight, drinking, smoking, cerebrovascular diseases, osteoporosis) ,cancers (stomach, cervix, lung, breast, liver, colon, prostate, ovary, pancreas, thyroid, esophagus) , infectious diseases (hepatitis, tuberculosis, sexually-transmitted diseases, parasites) , chronic obstructive respiratory diseases, chronic renal diseases (bacteriuria hematuria, proteinuria) , anemia, glaucoma, hearing loss, Alzheimer disease, stress, early psychiatric diseases. The health screening tests were basic physical examination, basic laboratory tests (CBC, urinalysis, liver function tests, lipid tests, glucose, HbAlc, uric acid, electrolytes, serological tests (HBsAg, HBs-Ab, HCV-Ab, HIV-Ab, VDRL) EKG, x-ray (chest PA, CT) , endoscopy (gastroscopy, colonoscopy) , sonography(abdomen, thyroid, pelvis, breast) ,cytology (cervix) , bone density, tumor markets (NMP22, alpha-FP, CEA, CA-19-9, CA12S, PSA) and eye tests. Advanced technologies, like CT, PET, MRI, MRT/Angio, molecular testings) were widely used in hospital health screening programmes .In summary, a variety of tests were utilized in health screening in Korea. Those tests were utilized by stages or according to sex and age in most of health screening programmes, however a few program used tests to excess disregarding health screening subjects.

Cryposporidium species have a wide host range. These coccidian parasites are found in close association with epithelial cells of many species of animals including mm. The gastrointestinal tract is most commonly affected in young ruminants and this parasite is thought to be considerable importance in calf diarrhea complex. Major outbreaks of cryptosporidiosis have been reported in calves, lambs, pigs and others including avian species. Cryptosporidiosis is transmitted by oocysts of Cryptosporidium species. Because cryptosporidiosis is common infection among animals, early literature considered it a zoonosis. Human infections contracted from calves, cats, and horse feces. However, the resrvoir host is longer considered the major source of infection. Mild cases of disease have been reported in farm workers. Immunosuppressed, very young and very old persons should avoid contact with this parasite because it may cause severe diarrhea. In order to detect of Crytosporidium sp infection from feces of cattle and pigs at Chonbuk Iksan and Kunsan area, sedimentation and modified acid fast stain were applied. The positive rate of Cryptosporidium sp infection from 1, 176 of cattle and 267 of pigs were 0.5 % and 16.8%, respectively. According to area in Iksan and Kunsan, the positive rates were 0.4% and 0.9% from cattle, and 18.9% and 12.1% from pigs, respectively. In cattle, positive detection rate was 0.6% in milking cows but not in Korean cattle.

Although Mycobacterium tuberculosis complex strains remain responsible for the majority of diseases caused by mycobacterial infections worldwide, the increase in HIV infections has allowed for the emergence of other non-tuberculous mycobacteria as clinically significant pathogens. However, Mycobacterium species has a long period of incubation, and requires serious biochemical tests such as niacin, catalase, and nitrate test that are often tedious. The development of rapid and accurate diagnostics can aid in the early diagnosis of disease caused by Mycobacterium. The current DNA amplification and hybridization methods that have been developed target several genes for the detection of mycobacterial species such as hps65, 16S rDNA, rpoB, and dnaj. These methods produce rapid and accurate results. In this study, PCR-restriction fragment length polymorphism analysis(PCR-RFLP) based on the region of the rpoB gene was used to verify the identification of non-tuburculosis Mycobacterium species. A total of 8 mycobacterial reference strains and 13 clinical isolates were digested with restriction enzymes such as Msp I in this study. The results of using this process clearly demonstrated that all 13 specimens were identified by rpoB gene PRA method. The PCR-RFLP method based on the rpoB gene is a simple, rapid, and accurate test for the identification of Mycobacterium.

To diagnose the vascular diseases from the viewpoint of hemodynamics, we need detailed quantitative hemodynamic information of related blood flows with a high spatial resolution of tens micrometer and a high temporal resolution in the order of millisecond. For investigating in-vivo hemodynamic phenomena of vascular circulatory diseases, a new diagnosing technique combining a medical radiography and PIV method was newly developed. This technique called 'Angiographic PIV system' consists of a medical X-ray tube, an X-ray CCD camera, a shutter module for generating double pulse-type X-ray, and a synchronizer. Through several preliminary tests, the feasibility of the Angiographic PIV technique was verified. For in-vivo applications to real blood flows, we developed tracer microcapsules, which were optimized to this system, made of a contrast material of iodine and a matrix material of PVA (polyvinylpyrrolidone). In near future, the Angiographic PIV technique will be used for understanding hemodynamic phenomena of vascular diseases and for their early detection.

The genome of the rice blast fungus Magnaporthe oryzae contains several types of transposable elements (TEs), and some TEs cause genetic variation that allows M. oryzae to evade host detection. We studied how five abundant TEs in rice pathogens, Pot3, Pot2, MAGGY, Line-like element (MGL) and Mg-SINE, are expressed under diverse conditions related to growth, development, and stress. Expression of Pot3 and Pot2 was activated in germinated conidia and mycelia treated with tricyclazole. Retrotransposon MAGGY was highly expressed in appressoria and tricyclazole-treated mycelia. MAGGY and Pot2 were also activated during the early and late stages of perithecia development. MGL was up-regulated in conidia and during conidial germination but not during appressorium formation. No noticeable expression of Mg-SINE was observed under most conditions. Our results should help investigate if and how condition-specific expressions of some TEs contribute to the biology and evolution of M. oryzae.
