3.Chronic Fatigue Syndrome.
Yeungnam University Journal of Medicine 2007;24(1):1-10
The chronic fatigue immune dysfunction syndrome (abbreviated CFIDS or CFS) is a disorder characterized by debilitating fatigue(over 6 months), along with cognitive, musculoskeletal, and sleep abnormalities. The etiology of this illness is unlikely to be a single agent. Findings to date suggest that physiological and psychological factors work together to predispose and perpetuate the illness. Diagnosis is made difficult by the nonspecific clinical findings and no available diagnostic testing. With no known cause or cure for the chronic fatigue and immune dysfunction syndrome, treatment is based on relieving symptoms and improving the quality of life of affected patients. There is emerging evidence that chronic fatigue syndrome may be familial. In the future, studies will examine the extent to which genetic and environmental factors play a role in the development of chronic fatigue syndrome. Most patients with CFS have psychiatric problems such as a generalized anxiety disorder, or major or minor depression, therefore, these mental health disorders may be correlated with the pathophysiology of the CFS. The treatment for CFS must be individualized, due to the heterogeneity of the CFS population. Also the treatment of CFS is built on a foundation of patient-physician relationship, respect and advocacy.

PURPOSE: The purpose of this study was to evaluate the relationship between radiation-induced activation of DNA repair genes and radiation induced apoptosis in A431 cell line. MATERALS AND METHODS: Five and 25 Gys of gamma radiation were given to A431 cells by a Cs-137 cell irradiator. Apoptosis was evaluated by flow cytometry using annexin V-fluorescein isothiocyanate and propidium iodide staining. The expression of DNA repair genes was evaluated by both Northern and Western blot analyses. RESULTS: The number of apoptotic cells increased with the increased radiation dose. It increased most significantly at 12 hours after irradiation. Expression of p53, p21, and hRAD50 reached the highest level at 12 hours after 5 Gy irradiation. In response to 25 Gy irradiation, hRAD50 and p21 were expressed maximally at 12 hours, but p53 and GADD45 genes showed the highest expression level after 12 hours. CONCLUSION: Induction of apoptosis and DNA repair by ionizing radiation were closely correlated. The peak time of inducing apoptosis and DNA repair was 12 hours in this study model. hRAD50, a recently discovered DNA repair gene, was also associated with radiation-induced apoptosis.

We performed a histopathologic and immunohistochemical study of 23 cases of surgically resected large cell undifferentiated carcinoma(LCUC) of the lung. The relative incidence of LCUC was 7.6% among the total resected cases of primary lung cancer over 7 years(1987-1993). The mean age of the patients was 56 years and 21 cases were male. The mean size of the mass was 5 cm and 11 cases were located peripherally. According to the histologic features, LCUC could be divided into three groups: squamous cell carcinoma-like(6 cases), adenocarcinoma-like(13 cases), and small cell carcinoma-like(4 cases) groups. The histologic differences were related to the variations of the immunohistochemical properties, but there were no differences in prognosis among these groups. Immunoreactivity to cytokeratin(CAM 5.2) was demonstrated in 22/23(96%). Carcinoembryonic antigen was positive in 13/23(57%). Neuron specific enolase and chromogranin were positive in 11/23(48%) and 5/23(22%), respectively. Vimentin was seen in 11/23(48%). From these observations, we could subclassify them by their immunologic phenotypes; exocrine features in 6/23(26%), neuroendocrine(NE) features in 4/23(17%), both exocrine and NE phenotypes in 7/23(30%), and 6 cases(26%) showed neither phenotype. The group with NE features showed a worse prognosis(P<0.05) and immunoreactivity for vimentin was also related to a worse prognosis(P<0.05). These findings imply that the immunohistochemical properties of LCUC are closely related to the histopathologic features. The groups, subdivided by histology and immunoreactivity, showed no prognostic difference except for the NE differentiation and reaction for vimentin.

Malignant histiocytosis(MH) is a rapidly progressive and usally fatal disorder characterized clinically fever, generalized weakness, lymphadeno athy, hepatosplenomegaly accompanied by jaundice, and purpura. The frequency of skin manifestations has been repoterd about 15% of MH patients. Papules, plaques and niidules are commonly met. Histopathologically MH shows infiltrations of atypical histiocyte; with uarious maturity in many organs including skin. We present a case of a 32-year-old female with MH involving not only lymph node, liver, spleen and bone marrow but also skin with vaorious features ; erythematous papules, annular purpuric patches, subcutaneous nodules and hemomagic nodules. Immunohist,ochemically the majority of patients atypical histiocytes in lesional skin shows a-1 antitrysin positive, but lysozyme negative. It may suggest that these are poorly differentiated atypical histiocytes rather than well differentiated ones.

INTRODUCTION: Osteoporosis, the most common metabolic bone disorder, is a condition of reduced bone density and increased susceptibility to fractures. Osteoporosis is a major public health problem and a significant cause of morbidity in postmenopausal women. Therefore family physicians as primary care physicians are in a key position for preventing and treating this disorder. So we studied the factors affecting to bone mineral density in postmenopausal women. MATERIALS AND METHODS: A total of 136 spontaneous postmenopausal women were participated in the study. They have measured spinal bone mineral density by dual energy x-ray absorptiometry from January 1992 to June 1995 at Yeungnam University Hospital. Age, height, weight, age at menarche and menopause, number of child and breast feeding child, history of oral pill ingestion, family history of osteoporosis, amount of milk and coffee ingestion, consumption of tobacco and alcohol and physical activity were assessed by qustionnaire and medical records. RESULTS: physical activity and weight were significant contributors. Physical activity is most the largest contributor. CONCLUSIONS: Among factors affecting to BMD in postmenopausal women, physical activity and weight were more important factors. Therefore continuous physical activity is significant factor to prevent osteoporosis in postmenopausal women.
