This study included patients with upper gastrointestinal hemorrhage who were treated in intensive care unit of GATA Haydarpasa Training Hospital, Division of Internal Medicine during 1 year. Medical and demographic data of the patients were recorded. These patients were followed for 3 months after being discharged from the intensive care unit. Of the 50 patients in the study, 18 were female (36%), 32 were male (64%). The mean age was 47±2 years, and the ages ranged between 17 and 89 years. We did not find any statistically significant results in our evaluation of the relationship between the mean platelet volume and the number of transfusions, endoscopic findings, and prognosis after 3 months of follow-up.

The aim of this study was to investigate the plasma apelin levels in diabetic patients with and without neuropathy. All consecutive diabetic patients who presented for routine follow-up at our outpatient clinic were invited to participate in this clinical study. Forty diabetic patients (20 female and 20 male) and twenty-two non-diabetic control subjects (9 female and 13 male) were included in the study. Neurological evaluations in diabetic subjects were done by nerve conduction studies and evaluated with the Neuropathy Symptom Score. Fasting plasma glucose, HbA1c, lipid and apelin levels were measured in each subject. The mean plasma apelin level was significantly higher in the diabetic patients than in the control subjects (p = 0.026). Apelin levels were statistically similar between diabetic patients with and without neuropathy (p = 0.43). Further, plasma apelin levels were found to be higher in diabetic patients with neuropathy when compared with those of healthy control subjects (p = 0.02). In diabetic patients with neuropathy, plasma apelin levels correlated significantly with diabetes duration (r = 0.5, p = 0.02). We propose that apelin levels in diabetic patients are higher in the presence of neuropathy and longer disease duration, although this might not solely suffice as an indicator for the presence of neuropathy in diabetic patients. Drawing attention to the possible association between the apelinergic system and diabetes mellitus, we believe that further studies with larger samples should be carried out also to investigate the presence of retinopathy and nephropathy.

Community acquired infections in elderly population

84%
EN
In geriatric practice, data regarding infections including the epidemiology, morbidity, and mortality are lacking. Our aim was to evaluate the frequency, location, microbiological and laboratory characteristics of infectious diseases in elderly population admitted to a training hospital. The patients were included total of 330 patients, aged over 65 with infection, seen between January 1, 2005 and January 1, 2006. In the result, of patients 136 (41%) had respiratory system infection, 90 (27%) urinary system infection, 39 (12%) gastrointestinal system infection, 34 (10%) bloodstream infections, 17 (5%) soft tissue infection, 8 (2%) central nervous system infections, and 6 (2%) others. Average length of hospitalization was 8.6±7.7 days. Mortality rate from all causes was 57 (17%). The most common infections in elderly patients were respiratory tract and urinary system infections, and there were no fever, leukocytes and high CRP levels in approximately 1/3 of cases. Infectious diseases may occur even in the absence of such infection indicators as fever, raised WBC count and high CRP level in the elderly population.
