Abstract
Malnutrition is fairly common in end-stage renal disease (ESRD) patients, persistent lack of appetite being a major symptom. Ghrelin and obestatin are two hormones that are involved in appetite and energy homeostasis. The present study examined ghrelin and obestatin levels in 24 ESRD patients undergoing haemodialysis and 24 age-matched healthy controls. Serum and saliva ghrelin and obestatin levels in the ESRD patients were significantly higher compared with controls, while saliva ghrelin and obestatin levels in all study participants were significantly higher than serum levels. Saliva ghrelin correlated with serum ghrelin and saliva obestatin correlated with serum obestatin in all study participants, although there was no correlation between ghrelin and obestatin levels. In conclusion, the results suggest that the kidneys may have a role in the metabolism and/or clearance of obestatin, as they do for ghrelin. Further studies are needed to determine if elevated levels of these hormones in ESRD patients contribute to the malnutrition that is common in these patients.

Abstract
PURPOSE This study focused on the effect of immuno-compromising conditions on the clinical presentation of severe listerial infection. PATIENTS AND METHODS Nine human listeriosis cases seen from 1991-2002 were reviewed. All adult patients, from whose blood, peritoneal fluid or cerebrospinal fluid (CSF) the L. monocytogenes was isolated, were included in this retrospective study. RESULTS Listeriosis presented as primary sepsis with positive blood cultures in 5 cases and meningitis with positive CSF cultures in 4 cases. All of these patients had at least one underlying disease, most commonly, hematologic malignancy, diabetes mellitus, amyloidosis and hepatic cirrhosis; 55.6% had received immunosuppressive or corticosteroid therapy within a week before the onset of listeriosis. The patients were adults with a mean age of 60 years. Fever, night sweats, chills and lethargy were the most common symptoms; high temperature (> 38 degrees C), tachycardia, meningeal signs and poor conditions in general were the most common findings on admission. The mortality rate was 33.3% and was strictly associated with the severity of the underlying disease. Mortality differences were significant between sepsis (20%) and meningitis (50%) patients. CONCLUSION Listeriosis as an uncommon infection in our region and that immuno- suppressive therapy is an important pre-disposing factor of listeriosis. Sepsis and meningitis were more common in this group of patients and had the highest case-fatality rate for food-borne illnesses.

Abstract
Background The optimal treatment regimen and duration of the therapy is still controversial in spinal brucellosis. The aim of this study is to compare the efficacy, adverse drug reactions, complications and cost of ciprofloxacin plus rifampicin versus doxycycline plus streptomycin in the treatment of spinal brucellosis. Methods The patients diagnosed as spinal brucellosis between January 2002 to December 2004 were enrolled into the study. Patients were enrolled into the two antimicrobial therapy groups (doxycycline plus streptomycin vs. ciprofloxacin plus rifampicin) consecutively. For the cost analysis of the two regimens, only the cost of antibiotic therapy was analysed for each patient. Results During the study period, 31 patients with spinal brucellosis were enrolled into the two antimicrobial therapy groups. Fifteen patients were included in doxycycline plus streptomycin group and 16 patients were included in ciprofloxacin plus rifampicin group. Forty-two levels of spinal column were involved in 31 patients. The most common affected site was lumbar spine (n = 32, 76%) and involvement level was not different in two groups. Despite the disadvantages (older age, more prevalent operation and abscess formation before the therapy) of the patients in the ciprofloxacin plus rifampicin group, the duration of the therapy (median 12 weeks in both groups) and clinical response were not different from the doxycycline plus streptomycin. The cost of ciprofloxacin plus rifampicin therapy was 1.2 fold higher than the cost of doxycycline plus streptomycin therapy. Conclusion Classical regimen (doxycycline plus streptomycin), with the appropriate duration (at least 12 weeks), is still the first line antibiotics and alternative therapies should be considered when adverse drug reactions were observed.

Abstract
Salmonella species may cause wide spectrum of infections changing from enterocolitis to sepsis. However, Salmonella meningitis in adults is a rare but important clinical condition with a high mortality rate. In this report, a 71 years old male patient with Salmonella enteritidis meningitis who was followed-up with the diagnosis of immune thrombocytopenic purpura and had been administered azothioprin and prednisolone, has been presented and similar cases in the literature have been reviewed. The cerebrospinal fluid culture yielded S. enteritidis, and the isolate was intermediate susceptible to ampicillin, susceptible to cefotaxime, trimethoprim-sulphametoxasole, ciprofloxacin and chloramphenicol. Our patient was successfully treated with ceftriaxone (2 x 2 gr i.v.) and discharged with total cure.

Abstract
Predisposing factors, antimicrobial susceptibility patterns, treatment and outcome were analysed for nine consecutive patients with nocardiosis. Predisposing factors were identified in six (67%) of the nine patients. Clinical syndromes of nocardial infection were pulmonary infection (three patients), cerebral infection (five patients) and disseminated infection (one patient). The predominant (60%) species was Nocardia farcinica rather than the Nocardia asteroides complex. Treatment was started empirically, modified according to the antimicrobial susceptibility pattern, and then continued for 6-12 months. Overall mortality was 33%, with death being caused by the Nocardia infection in two cases.

Abstract
The aim of the study was to investigate the hypothalamo-pituitary-adrenal (HPA) axis by ACTH stimulation test and the changes in adrenal size in acute brucellosis before and after therapy in a prospective study. Sixteen patients with acute brucellosis and 15 healthy subjects were included in the study during the last two years. Cortisol levels were assessed before, 30 and 60 minutes after ACTH (250 microg i.v.) injection and the size of the adrenals was measured in both groups. Mean basal cortisol levels in the patients before the therapy and after the therapy were 22.1 +/- 6.9 microg/dL and 11.3 +/- 6.0 microg/dL, respectively. The difference was statistically significant (p<0.001). There was also statistically significant difference for basal cortisol levels between the healthy subjects (12.2 +/- 4.6 microg/dL) and the patients before the therapy (p<0.001). Peak cortisol responses to ACTH were higher before the therapy in the patients with acute brucellosis (39.3 +/- 10.7 microg/dL) than in the healthy subjects (30.4 +/- 4.8 microg/dL, p = 0.014). However, there was no significant difference for peak cortisol levels in the patients before and after the therapy (32.7 +/- 8.0 microg/dL). Mean basal cortisol levels and peak cortisol responses to ACTH between the patients after the therapy and the healthy controls were similar. Both the maximum width of the adrenal glands and the width of the adrenal limbs were significantly greater before the therapy compared to healthy subjects and post-treatment period. We concluded that the HPA axis is activated and the adrenal glands are enlarged in acute brucellosis, which is reduced after appropriate therapy.

Abstract
Left ventricular hypertrophy (LVH) is very common in haemodialysis patients. We measured left ventricular mass in three groups of haemodialysis patients: group A (n = 40) were normotensive and receiving a strict salt-restricted diet; group B (n = 23) were normotensive and receiving anti-hypertensive drugs; and group C (n = 43) were hypertensive despite anti-hypertensive drug treatment. The interdialytic weight gain in group B and group C was significantly higher than in group A; the mean left atrial index and left ventricular end-systolic and end-diastolic diameter indices were all higher in group B than in group A. The interventricular septum and posterior wall were significantly thicker in group B and group C than group A, resulting in a higher left ventricular mass index. Left ventricular systolic and diastolic function parameters were slightly better in group A than in the other groups. These results show that strict fluid volume control decreases blood pressure, reduces dilated cardiac compartments and corrects LVH more effectively than lowering blood pressure without correcting the volume overload.

Abstract
To determine the frequency, risk factors and mortality of nosocomial pneumonia a prospective study was conducted in the intensive care units. In the study period, 2402 patients were included. The nosocomial pneumonia was defined according to the Centers for Disease Control Criteria. Overall, 163 (6.8%) of the patients developed nosocomial pneumonia and 75.5% (n = 123) of all patients with nosocomial pneumonia were ventilator-associated pneumonia. 163 patients who were admitted to the intensive care unit during the same period but had no bacteriologic or histologic evidence of pneumonia were used as a control group. The APACHE II score, coma, hypoalbuminemia, mechanical ventilation, tracheotomy, presence of nasogastric tube were found as independent risk factors. Crude and attributable mortality were 65% and 52.6%, respectively. The mortality rate was five times greater in the cases (OR: 5.2; CI 95%: 3.2–8.3). The mean length of stay in the intensive care unit and hospital in the cases were longer than controls (p < 0.0001). Patients requiring mechanical ventilation have a high frequency of nosocomial pneumonia.

Abstract
In total, 177 patients with bloodstream infections caused by Staphylococcus aureus (BSISA) were investigated prospectively between June 1999 and June 2001. Of these, 19.8% had community-acquired BSISA, while 80.2% had nosocomial BSISA. Surgical intervention, foreign body, mechanical ventilation, total parenteral nutrition, and previous antibiotic treatment were found to be important risk factors for the nosocomial BSISA group. Secondary BSISA formed a greater proportion (62.9%) of community-acquired infections than of nosocomial infections (26.8%; p 0.0001). Catheter-related nosocomial BSISA was observed in 72.1% of patients. The suppurative complication rate was significantly higher among community-acquired infections (22.9%) than among nosocomial infections (6.3%; p 0.008). Of the nosocomial BSISA, 65.5% were methicillin-resistant. Analysis of 80 methicillin-resistant S. aureus isolates by pulsed-field gel electrophoresis identified ten main clones (A-J), but 61 (76.3%) of the 80 isolates belonged to clone A.

Abstract
A retrospective study was performed to assess the epidemiology, diagnosis, clinic, and laboratory of the patients with tuberculous meningitis (TBM) in a multicentral study. The medical records of adult cases with TBM treated at 12 university hospitals throughout Turkey, between 1985 and 1998 were reviewed using a standardized protocol. The diagnosis of TMB was established with the clinical and laboratory findings and/or microbiological confirmation in cerebrospinal fluid (CSF). The non-microbiologically confirmed cases were diagnosed with five diagnostic sub-criteria which CSF findings, radiological findings, extra-neural tuberculosis, epidemiological findings and response to antituberculous therapy. A total of 469 patients were included in this study. Majority of the patients were from Southeast Anatolia (164 patients, 35.0%) and (108 patients, 23.0%) from East Anatolia regions. There was a close contact with a tuberculous patient in 88 of 341 patients (25.8%) and with a tuberculous family member in 53 of 288 patients (18.4%). BCG scar was positive in 161 of 392 patients (41.1%). Tuberculin skin test was done in 233 patients and was found to be negative in 75. Totally 115 patients died (24.5%) of whom 23 died in 24 hour after admittance. The diagnosis was confirmed with clinical findings and CSF culture and/or Ziehl-Nelson staining in 88 patients (18.8%). Besides clinical criteria, there were three or more diagnostic sub-criteria in 252 cases (53.7%), two diagnostic sub-criteria in 99 cases (21.1%), and any diagnostic sub-criteria in 30 patients (6.4%). Since TBM is a very critical disease, early diagnosis and treatment may reduce fatal outcome and morbidity.

Abstract
At the end of 1999, a case of polymicrobial ventriculitis in the Department of Neurosurgery followed by an outbreak of Serratia marcescens mediastinitis in the intensive care unit of cardiovascular surgery occurred. These nosocomial surgical infections were considered to be the result of contamination of surgical sites with inadequately sterilized instruments or theatre linen. An epidemiological survey was focused on the central sterilization unit of the hospital. The microbiological results of this survey proved that the cause of the outbreak was the use of inadequately decontaminated theatre linen. This study indicates that strict infection control measures including the control of sterilization procedures and a well-organized infection control team are necessary to prevent nosocomial surgical infections.

Abstract
INTRODUCTION The aim of the study was to assess the prognostic importance of basal cortisol concentrations and cortisol response to corticotropin, and to determine the effects of physiological dose steroid therapy on mortality in patients with sepsis. METHODS Basal cortisol level and corticotropin stimulation test were performed within 24 hours in all patients. One group (20 patients) received standard therapy for sepsis and physiological-dose steroid therapy for 10 days; the other group (20 patients) received only standard therapy for sepsis. Basal cortisol level was measured on the 14th day in patients who recovered. The outcome of sepsis was compared. RESULTS Only Sequential Organ Failure Assessment (SOFA) score was found related to mortality, independent from other factors in multivariate analysis. No significant difference was found between the changes in the percentage of SOFA scores of the steroid therapy group and the standard therapy group in survivors, nor between the groups in basal and peak cortisol levels, cortisol response to corticotropin test and mortality. The mortality rates among patients with occult adrenal insufficiencies were 40% in the steroid therapy group and 55.6% in the standard therapy group. DISCUSSION There was a trend towards a decrease in the mortality rates of the patients with sepsis who received physiological-dose steroid therapy. In the advancing process from sepsis to septic shock, adrenal insufficiency was not frequent as supposed. There was a trend (that did not reach significance) towards a decrease in the mortality rates of the patients with sepsis who received physiological-dose steroid therapy.

Abstract
OBJECTIVE To assess predictors of mortality and neurological sequelae in patients with tuberculous meningitis (TBM). METHODS Patients with TBM treated at 12 university hospitals in Turkey between 1985 and 1997 were evaluated using a standardised protocol applied retrospectively. Variables associated with hospital mortality as well as with the presence of neurological sequelae at 6 months were determined using logistic regression models. RESULTS Four hundred and thirty-four patients between the ages of 13 and 83 years (mean 33 years) were evaluated. Sixty-eight per cent of these patients presented with Medical Research Council Stage II or III. One hundred and one patients (23.3%) died and 67 (27%) of evaluable survivors had neurological sequelae. In multi-variable analysis, convulsion (OR 3.3, 95%CI 1.2-9.0, P = 0.02), comatose mental status (OR 6.0, 95%CI 3.6-10.2, P = 0.01), and delayed or interrupted treatment (OR 5.1, 95%CI 2.4-11.2, P = 0.01) were shown to be predictors for mortality. The presence of extra-meningeal tuberculosis (OR 2.1, 95%CI 1.1-4.2, P = 0.035), cranial nerve palsy (OR 2.6, 95%CI 1.4-4.2, P = 0.01), hemiparesia/focal weakness (OR 9.3, 95%CI 3.8-22.6, P = 0.01), hemiplegia/multiple neurological deficit (OR 7.1, 95%CI 2.14-23.38, P = 0.01) and drowsiness (OR 4.2, 95%CI 2.04-8.82, P = 0.01) were independent predictors of neurological sequelae at 6 months following hospital discharge. CONCLUSION The results of this study emphasise the importance of prompt and uninterrupted anti-tuberculosis therapy for tuberculous meningitis. The presence of seizures or coma on admission to hospital are important predictors for mortality, while the presence of focal neurological signs is a predictor for persistent neurological sequelae in survivors.

Abstract
A case is reported of a 43-year-old man who presented prostatitis and hepatitis due to Brucella melitensis. His symptoms were icterus, weakness, anorexia, fever, and urinary discomfort. Physical examination revealed icterus and hepatosplenomegaly. Lymphomonocytosis, elevated erythrocyte sedimentation rate and abnormal liver functions had been detected in laboratory tests. Brucella melitensis was isolated from prostatic fluid and blood cultures.

Abstract
The basal cortisol level and cortisol response to ACTH stimulation test were assessed in patients with sepsis, the results being compared to a control group of 30 healthy persons. The study group included 49 patients with sepsis and 30 healthy subjects as a control group. The mean age in the study group was 42.6 +/- 18.7 years and 41.4 +/- 12.1 years in the control group. Fifteen of the 49 (30.6%) patients had hospital-acquired and 34 (69.4%) patients community-acquired sepsis. Etiological agent was isolated in 35 (71.4%) patients (57.1% gram negative bacteria and 34.3% gram positive bacteria, plus 8.6% polymicrobial). Fourteen of 49 (28.6%) patients died. Mean basal cortisol level was 597.1 +/- 304.6 nmol/l (range 217.8-1667.9) in the study group and 460.2 +/- 180.8 nmol/l (range 253.6-988.9) in the control group. Mean basal cortisol level in the study group was significantly higher than that of the control group (p < 0.05). Mean basal cortisol level was found to be 725.5 +/- 448.9 nmol/l in the patients who died and 545.8 +/- 210.9 nmol/l in the patients who recovered. The difference between the two groups was found to be significant (p < 0.05). ACTH stimulation test was performed in 43 of the patients and 30 healthy subjects. Cortisol response was significantly lower (mean 277.7 +/- 216.9 nmol/l) in the patients than that detected in the control group (mean 519.6 +/- 279.2) (p < 0.001). Mean cortisol response in the patients who died was 227.2 +/- 224.5 nmol/l and 302.1 +/- 212.7 nmol/l in the patients who recovered (p > 0.05). Adrenocortical insufficiency was detected in 16.3% of the patients and 42.9% of these patients died. In conclusion, sepsis is characterized by high basal cortisol level which may show a poor prognosis and a blunted cortisol response to ACTH stimulation. A small percentage of patients with sepsis may develop adrenocortical insufficiency.
