MRI was performed in seven patients with presumed central pontine and extrapontine myelinolysis. The underlying diseases were diabetes, lung cancer, Wilson disease, trauma, alcoholism, renal insufficiency and hemodialysis. CPM was found in four cases (in two of them extrapontine lesions were considered as resulting from Wilson disease), CPM and EPM in three patients. The localization of extrapontine changes included cerebellum, cerebral peduncles, caudate and lentiform nuclei, internal capsules, white matter and cortex of the cerebrum.

A 76-year-old man in whom interstitial pneumonia and diabetes mellitus had been diagnosed complained of bloody sputum in August, 1998. Chest radiography disclosed irregular shadows in the left lower lung field. Chest computed tomography (CT) scans revealed a cyst and a small nodular lesion in the left S6 segment. Although primary lung cancer was suspected, we did not detect any malignant cells in the transbronchial lung biopsy specimen. CT scans in January 2000 showed a ball-like shadow in the thick-walled cyst in the left S6 segment. Cytologic examination of the sputum and the bronchial lavage fluid from the left B6 revealed squamous cell carcinoma. Left lower lobectomy and mediastinal lymph node dissection were performed. Pathological examination revealed that moderately differentiated squamous cell carcinoma had extensively invaded the wall of the cyst in the left S6 and S10 segments, and was accompanied with aspergilloma. Abnormal thickening of a cyst wall may in some cases suggest the presence of lung cancer.

Low socioeconomic status is associated with high mortality, but the extent to which socioeconomic status affects particular diseases and whether socioeconomic status effects have changed over time are uncertain. The authors used education as a marker for socioeconomic status in a study of two large American Cancer Society cohorts (follow-up, 1959-1996). Low education was associated with higher death rates in both cohorts from all causes and most specific causes, except breast cancer and external causes among women. Life expectancy in the more recent cohort was 4.8 years shorter for men and 2.7 years shorter for women for the least versus the most educated. The inverse relation between education and mortality was strongest for coronary heart disease, lung cancer, diabetes, and chronic obstructive pulmonary disease; moderate for colorectal cancer, external causes (men only), and stroke; weak for prostate cancer; and reversed for external causes among women. The direction of a weak gradient for breast cancer differed for those with and without prevalent breast cancer at baseline. Adjustment for conventional risk factors, probable intermediate variables between education and mortality, diminished but did not eliminate the observed educational/mortality gradients. Temporal trends showed increasing mortality differences by education for coronary heart disease, diabetes, and lung cancer for women.

Elderly patients with lung cancer tend to have significant coexisting diseases and less aggressive treatment is often required. To investigate the clinicopathological features of non-small cell lung cancer (NSCLC) in elderly patients who were treated with radiotherapy, we reviewed the medical records at our division. Among the 189 patients 70 years or older between 1992 and 2001, 28 (14.8%) patients were treated with radiotherapy (elderly group). In the elderly group, there was a medical history of chronic obstructive pulmonary disease (COPD) (57.1%), cardiovascular disease (32.1%), diabetes mellitus (18.5%), malignant disease (18.5%), or cerebrovascular disease (10.7%). Moreover, in the elderly group, 17 (60.7%) patients had two or three coexisting diseases. There was statistical difference between the elderly group and the younger group (less than 70 years patients) with regard to COPD (p<0.001). Also there was statistical difference between the elderly group and the younger group with regard to number of coexisting diseases (p=0.002). In the elderly group, forced expiratory volume in one second (FEV1), forced expiratory volume (FVC), FEV1/FVC and diffusing capacity of the lung for carbon monoxide (DLCO) were statistically significant impaired to compare with those in the younger group (p<0.001, p=0.030, p<0.001 and p=0.024, respectively). In the elderly group, 10.7% of patients had concurrent chemoradiotherapy, however, 38.5% of patients of the younger group received concurrent chemoradiotherapy. There was a statistical difference between the two groups (p=0.026). Adequate palliative care to provide prolonged quality survival is an appropriate primary goal of therapy for lung cancer in the elderly and radiotherapy is thought be one of the less invasive treatments.

We describe the actual situation of and measures for medical risk factors of tuberculosis in compromised hosts and elderly people. Cases of diabetes mellitus, collagen disease and lung cancer administered corticosteroid preparations are taken up as compromised hosts. The frequency of TB patients having diabetes mellitus concurrently tends to increase, and the relative risk of diabetics developing tuberculosis is also high. Physicians giving diagnosis and treatment of diabetes mellitus should understand that diabetics belong to the high risk group of developing tuberculosis and perform chest X-ray examination periodically. In order to prevent the development of tuberculosis from diabetics, it is considered preferable to give chemoprophylaxis where there is no history of TB treatment and healing of TB has been found on the chest X-ray films. Where corticosteroid preparation, more than 10 mg in terms of prednisolone is administered over a long period of time for collagen diseases except rheumatoid arthritis and lung cancer, chemoprophylaxis is considered desirable. As for the present situation of the elderly TB patients among in-patients at our hospital, the elderly often had serious complications, their prognosis was poor and they often died of the diseases other than tuberculosis. To strengthen the measures to deal with tuberculosis in the elderly, early discovery and prophylaxis of pulmonary tuberculosis are considered. For the early discovery when the patient is symptomatic, the examination of sputum along with chest X-ray examination is important. As for the periodical health examination, the patients with the risk of infection to those around them being high need to undergo the health examination for sure. As the prophylactic measures, chemoprophylaxis is recommended where there is no history of TB treatment and healing of tuberculosis has been found on chest X-ray films.

The term radial segmentation (RS) is applied to a characteristic nuclear deformation observed in peripheral blood in vitro in some neoplastic and normal cells. It concerns al mononuclear cells. RS positive lymphocytes were found as CD 4 cells. Different conditions and substances, i.e. anticoagulant or cyclosporin can induce the formation of RS nuclei in vitro. Elevated ratio of RS nuclei in peripheral blood has been observed in patients with some autoimmunological diseases i.e. rheumatoid arthritis, diabetes mellitus insulin-dependent, sarcoidosis. Reduced ratio of RS nuclei was observed in neoplastic diseases. The aim of the study was to analyze the incidence of RS nuclei of lymphocytes in vitro in peripheral blood (induced by cyclosporin) in patients with non-small cell lung cancer (NSCLC). Heparinized peripheral blood was obtained from controls and patients with primary NSCLC. The blood was incubated with cyclosporin, and then lymphocytes were isolated by Lymphoprep. RS positive lymphocytes were counted in smears stained with MGG stain. In peripheral blood from healthy donors the average incidence of lymphocytes RS was 3.314% and in patients with NSCLC 4.481% respectively. The difference between controls and patients with NSCLC was not significant. No correlation was found between incidence of RS and stadium of lung cancer.

This study examines the association between education and mortality from specific causes of death based on mortality records for 1996 and 1997, and 1996 population census data from the Region of Madrid (Spain). Poisson regression models were used to estimate the percentage increase in mortality associated with 1 year less education. The percentage increases in mortality from stomach cancer, lung, bladder and liver cancers, for aids, chronic obstructive pulmonary disease, pneumonia and influenza, and chronic liver disease and cirrhosis were higher in men than in women, whereas the percentage increases in mortality from colon cancer, diabetes mellitus, ischemic heart disease and nephritis, nephrosis and nephrotic syndrome were higher in women. The results found for some causes of death--lung cancer, ischemic heart disease, diabetes mellitus and chronic obstructive pulmonary disease--reflect the variations by educational level in the prevalence of lifestyle-related risk factors in men and women. Various hypotheses have been suggested for other causes of death, but it is not known why the magnitude of the association between education and mortality from some causes of death differs between men and women. Future studies of this subject may provide some clues as to the underlying mechanisms of this association.

OBJECTIVE: To compare kinetics and accumulation of 2-[fluorine-18]-fluoro-2-deoxy-D-glucose (FDG) in primary lung cancer between diabetic and non-diabetic patients using positron emission tomography (PET).METHODS: Five diabetic patients and 21 non-diabetic patients underwent dynamic FDG-PET to image untreated primary lung cancers. Standardized uptake value normalized for lean body mass (SUL) was determined in tumor, blood, muscle, and lung. A 3-compartment metabolic model was applied to FDG kinetics in tumors in 24 of 26 patients.RESULTS: At the time of PET scans, serum glucose levels were elevated in 5 diabetic patients, while 21 non-diabetic patients showed normal glucose levels. In diabetic patients, tumor SUL, tumor/blood and tumor/muscle SUL ratios were significantly decreased (P < 0.02) and also tumor/lung SUL ratio declined (P = 0.064), as compared to non-diabetic patients. In addition, the rate constant for FDG phosphorylation (k3) and influx constant (Ki) in diabetic patients were significantly lower than those in non-diabetic patients (P < 0.02).CONCLUSION: In diabetic patients, the rate of FDG accumulation in tumors is decreased, and tumor targeting with FDG is impaired. Diabetes may reduce the sensitivity of FDG-PET for lung cancer detection.

As for the measures for tuberculosis in Japan, BCG inoculation and chemoprophylaxis have been done with emphasis placed on children and young people. Since, however, about 90% are older than 30 years and more than 50% are older than 60 years among the new TB patients, measures, particularly chemoprophylaxis aiming at the middle-old aged people are needed in the future. We discuss the method to select cases for chemoprophylaxis as to the cases of diabetes, collagen diseases and lung cancer administered corticosteroid preparations as well as the cases of Crohn's disease and rheumatoid arthritis administered anti-TNF-alpha among compromised hosts. In diabetics, chemoprophylaxis is necessary for those who show healing of TB despite there being no history of TB treatment. Where a corticosteroid preparation, more than 10 mg in terms of prednisolone is administered over a long period of time for collagen disease and lung cancer, chemoprophylaxis is necessary for those who show healing of TB despite there being no history of TB treatment and those who are suspected of having TB infection by a tuberculin test. In the cases of Crohn's disease and rheumatoid arthritis administered anti-TNF-alpha, chemoprophylaxis is necessary for those who show healing of TB despite those who are suspected of having TB infection by a tuberculin test. The administration period of INH as chemoprophylaxis should preferably be set at 9 months instead of 6 months hitherto used.

Epidemiological research has consistently shown that physical activity decreases the risk of coronary heart disease, hypertension and stroke. The finding that a low level of physical activity is a major determinant of the growing epidemics of obesity is also firm and consistent. The direct association existing between a sedentary lifestyle and the incidence of diabetes mellitus is solid and of great importance for public health. Additional benefits from a a physically active lifestyle are a reduction in the incidence and prevalence of osteoporosis, lower risk of falls and fractures in the elderly, and a lower risk of anxiety and depression. Although evidence is less consistent, low levels of physical activity have been related to a higher risk of colon, breast and lung cancer. Some preliminary evidence relates physical activity with a lower risk of dementia. During the last three decades a huge amount of epidemiological research has led to uniform conclusions about the benefits of a physically active lifestyle. In spite of this fact, the prevalence of sedentary lifestyles is rising. Therefore, health promotion interventions are urgently needed to reach the objective of engaging in regular and moderate physical activity for at least 30 minutes per day in most, preferably all, days of the week.
