Abstract
INTRODUCTION The long-term prognosis of patients with community-acquired pneumonia (CAP) has attracted increasing interest in recent years. The objective of the present study is to investigate the short and long-term outcomes in hospitalized patients with CAP and to identify the predictive factors associated with mortality. PATIENTS AND METHODS The study was designed as a retrospective, multicenter, observational study. Hospitalized patients with CAP, as recorded in the pneumonia database of the Turkish Thoracic Society between 2011 and 2013, were included. Short-term mortality was defined as 30-day mortality and long-term mortality was assessed from those who survived 30 days. Predictive factors for short- and long-term mortality were analyzed. RESULTS The study included 785 patients, 68% of whom were male and the mean age was 67±16 (18-92). The median duration of follow-up was 61.2±11.8 (37-90) months. Thirty-day mortality was 9.2% and the median survival of patients surviving 30 days was 62.8±4.4 months. Multivariate analysis revealed that advanced age, the absence of fever, a higher Charlson comorbidity score, higher blood urea nitrogen (BUN)/albumin ratios and lower alanine aminotransferase (ALT) levels were all predictors of long-term mortality. CONCLUSION Long-term mortality following hospitalization for CAP is high. Charlson score and lack of fever are potential indicators for decreased long-term survival. As novel parameters, baseline BUN/albumin ratios and ALT levels are significantly associated with late mortality. Further interventions and closer monitoring are necessary for such subgroups of patients.

Abstract
PURPOSE To explore the utility of p57, c-erbB-2, CD 117, and Bel-2 immunostaining in the differential diagnosis of complete hydatidiform mole (CHM), partial hydatidiform mole (PHM), and hydropic abortion (HA). MATERIALS AND METHODS Immunohistochemical expression of the p57, c-erbB-2, CD117, and Bel-2 proteins were investigated semi-quantitatively using paraffin-embedded tissue sections from histologically unequivocal cases of CHM (n = 20), PHM (n = 23), and HA (n = 17). RESULTS All cases of CHM exhibited a striking absence of p57 expression. The percentage of positive p57 staining was similar between PHMs (73.9%) and HAs (76.5%) (p >0.05). The comparison of c-erbB-2 expression revealed a significantly higher percentage of positive c-erbB-2 staining in CHMs (45%) compared with that in PHMs (8.7%) and HAs (5.9%) (p = 0.006 and 0.01, respectively). The CD 117 expression pattern (immunoreactivity score, percentage of positive cells, and staining intensity) was significantly lower in HAs compared with that in PHMs and CHMs (p < 0.05 for all). A significantly increased Bel-2 expression pattern was observed in HAs compared with that in PHMs and CHMs (p < 0.05 for all). CONCLUSION Immunohistochemical examination of p57, c-erbB-2, CD 117, and Bel-2 expression represents a relatively simple, reliable, and cost-efficient procedure to definitively distinguish among CHM, PHM, and HA.

Abstract
Pneumococcal disease can be divided into invasive disease, i.e. when bacteria are detected in normally sterile body fluids, and noninvasive disease. Pneumococcal disease occurs more frequently in younger children and older adults. It is estimated that, in 2050, 30.3% of the European population will be ≥65 yrs old, compared with 15.7% in 2000. Preventive medicine, including vaccination, is essential for the promotion of healthy ageing. Uptake rates for influenza vaccination in the elderly are generally low, despite recommendations in many countries. In addition, it has been reported that influenza infections can make people more susceptible to pneumococcal infections. Despite pneumococcal vaccination, case fatality rates for patients hospitalised with invasive pneumococcal disease have remained at around 12% since the 1950s. Even when effective antibiotic therapy is administered, mortality can be high amongst immunocompetent patients in intensive care. Timely and accurate diagnosis of pneumococcal disease and identification of patients at high risk of poor outcome is essential to ensure that adequate treatment, including hospitalisation when necessary, is implemented as early as possible. Improved diagnostic techniques and more efficacious treatments may help to reduce the burden of pneumococcal disease, but preventive measures, such as influenza and pneumococcal vaccination, should be promoted in order to avoid preventable disease, particularly in the elderly.

Abstract
The combination of hepatitis B immunoglobulin (HBIG) and antivirals (nucleos[t]ide analogs) has extended the applicability of orthotopic liver transplantation (OLT) for patients with hepatitis B virus (HBV)-related liver disease. However, HBIG administrations have an extremely high cost. Herein, we evaluated our results with low-dose, on-demand, intramuscular HBIG plus lamivudine (LAM) prophylaxis after OLT. The HBV DNA status in 40 patients at the time of OLT determined the treatment: group A (n = 22), HBV DNA (-), no antiviral pretreatment; group B (n = 11), HBV DNA (-), after LAM; group C (n = 3), HBV DNA (+) after LAM (LAM resistance/Adefovir [ADV] unavailable); group D (n = 2), HBV DNA (+), no antiviral pretreatment; and group E (n = 2), HBV DNA (-) after LAM + ADV (LAM resistance/ADV available). Five patients died within 12 months after OLT unrelated to HBV infection. The remaining 35 patients were followed for a median duration of 16 months (range, 6-93 months). Only two recipients from group C, who were transplanted despite LAM resistance + no ADV pretreatment, revealed recurrent HBV infections at 14 and 16 months posttransplantation; they were then treated successfully with ADV as it became available. The third group C recipient had undetectable HBV DNA at 18 months after OLT. The mean cumulative doses of HBIG administered within the first, second, and third years were 34,014, 5258, and 5090 IU, respectively. In conclusion, low-dose, on-demand, intramuscular HBIG plus (LAM +/- ADV) prophylaxis is a safe, efficient, and cost-effective regimen to prevent recurrent HBV infection following OLT. OLT despite untreated LAM resistance may require sustained higher serum HBsAb levels after surgery.

Abstract
BACKGROUND Heart transplantation is an important therapeutic option for patients with end-stage disease, but is associated with major pulmonary complications. PATIENTS AND METHODS We retrospectively reviewed the posttransplant follow-up of 34 orthotopic heart transplant recipients. RESULTS Two of the 34 patients died of cardiac failure in the early postoperative period. Among the surviving patients, 10 (31.3%) developed pulmonary complications, all within the first 6 months: hospital-acquired bacterial pneumonia in five, fungal pneumonia in three, posttransplant lymphoproliferative disease in one, and community-acquired pneumonia in one patient. None of the patients developed transplantation-related malignancy. The overall mortality was 35.3%. Pneumonia-related mortality rate of 14.7% was due to early-onset nosocomial pneumonias, which were caused by bacterial and opportunistic microorganisms. Extrapulmonary causes of mortality were cardiac failure, meningitis, septicemia, and acute rejection. Cytomegalovirus antigenemia in the first month was associated with a poor prognosis. The frequency of pulmonary complications was higher among older patients and those who developed moderate rejection in the first month (P=.014 and P=.036, respectively). CONCLUSION Pulmonary infections after heart transplantation occurred more frequently during the first 6 months posttransplantation, accounting for a significant portion of the posttransplantation mortality.

Abstract
OBJECTIVE Chlamydia pneumoniae (C pneumoniae) is a common cause of a usually mild, community acquired pneumonia. This organism, however, can spread from the respiratory tract into other parts of the body and has been detected in up to 70% of atheromatous lesions in blood vessels. Although the exact mechanism of the C Pneumoniae contribution to the pathogenesis of atherosclerosis remains unknown, prophylactic antibiotic trials are planned for people at high risk for coronary disease. METHOD In this study the authors aimed to investigate C pneumoniae DNA content in the cerebral aneurysmal sac tissue with the aid of polymerase chain reaction (PCR) method. C pneumoniae DNA was searched in 15 surgically clipped and removed aneurysmal sac tissue and in two tumour (an ependymoma of the fourth ventricle and a craniofaringoma) samples by touchdown enzyme time release PCR (TETR PCR) targeting 16S rRNA gene and by nested PCR targeting ompA gene. RESULTS Both PCR methods were sensitive to detect in C pneumoniae 4x10(-2) genomes. C pneumoniae DNA was not detected in any of the 17 sample tissues of these patients. CONCLUSION The contribution of C pneumoniae in the development of intracranial aneurysms cannot be excluded despite the results of this study. Further studies on the possible role of C pneumoniae or any other micro-organisms in the pathogenesis of aneurysms should be performed.

Abstract
This study aimed to determine the incidence of tuberculosis among hospital employees in four major urban institutions, which employ nearly 90% of all hospital workers caring for adult patients in a city of 2.5 million inhabitants. It also had the objective of finding out whether this incidence changes according to the in-hospital setting, i.e. the departments, and thus, whether tuberculosis can be considered to pose an occupational risk. The study population consisted of all healthcare workers of the four hospitals between 1986 and 1998. From these, those who developed tuberculosis within this period were determined and were considered as the case group. All the remaining employees constituted the control group. Fifty-nine healthcare workers were found to have developed the disease. The annual incidence was found to range between 0.016 and 0.139%. Tuberculosis was seen 3 times more frequently among the hospital employees than the general population. The workers in departments of chest diseases were found to have a higher risk than those of other departments (OR: 6.37, CI: 3.69-11.00). Similarly, the nurses were also at a higher risk than the doctors (OR: 2.63, CI: 1.12-6.36). These findings suggest that tuberculosis can be considered as an occupational disease.

Abstract
BACKGROUND Diabetes mellitus has been reported to modify the presenting features of pulmonary tuberculosis, but there are varying data, particularly regarding the association with lower lung field involvement. OBJECTIVES To determine whether diabetes mellitus alters the clinical and radiographic manifestations of tuberculosis in nonimmunocompromised hosts and to define the determinants of lower lung field involvement. METHODS A retrospective review of the records of all patients with tuberculosis and diabetes mellitus seen during a 14-year period and of an age- and sex-matched nondiabetic control group with tuberculosis was carried out. The duration of symptoms, tuberculin reaction, bacteriologic and radiographic findings of the two groups were compared. RESULTS The presence of diabetes mellitus was found not to have an effect on patients' symptomatology, bacteriology results, tuberculin reaction and localization of pulmonary infiltrates. On the other hand, fewer diabetic patients were smear-positive and fewer had reticulonodular opacities compared with the control patients. A higher number of insulin-dependent diabetic patients presented with cavitary disease as compared with nondiabetic controls. Lower lung field tuberculosis was significantly associated with female gender and, in patients older than 40 years, was more frequently observed in diabetics. CONCLUSION These data show that diabetes does not affect the presenting features of pulmonary tuberculosis to a large extent and is only associated with lower lung field disease in older patients.

Abstract
OBJECTIVE This study aimed to compare the efficacies of 3-day and 10-day courses of methylprednisolone (MP) treatment in severe COPD exacerbations necessitating hospitalization for respiratory failure. DESIGN Prospective, randomized, single-blind study. SETTING Tertiary-care center. PATIENTS AND METHODS Thirty-six patients were included in the study and randomized into two groups: group 1 received MP, 0.5 mg/kg q6h for 3 days, and group 2 was administered the same dosage of MP for the first 3 days, after which it was tapered and terminated on the tenth day. There was no difference between the groups for age, baseline FEV(1), PaO(2), PaCO(2), and pH levels. One patient in group 1 who developed pneumothorax and one patient in group 2 who had steroid-related psychosis could not complete the study. RESULTS Both groups showed significant improvements in PaO(2) and FEV(1) levels, but these were more marked in group 2 (p = 0.012 and p = 0.019, respectively). There was a significant increase in FVC levels in group 2 only (p = 0.003). Group 2 also had a more marked improvement in dyspnea on exertion. There was no difference between the two groups with regards to other parameters, including pH, PaCO(2) levels, and other symptom scores. Six patients in group 1 and five patients in group 2 developed new exacerbations within the following 6 months. Hyperglycemia occurred in two patients in each group. CONCLUSION In severe COPD exacerbations, a 10-day course of steroid treatment is more effective than a 3-day course in improving the outcome, but has no benefit in reducing exacerbation rates.

Abstract
The case of a 62-year-old woman with a type II congenital broncho-esophageal fistula is presented. She had had recurrent pulmonary infections that were more prominent in the last 15 years. A barium swallow examination showed a communication between the esophagus and the right lower lobe. High resolution computed tomographic scan of the chest revealed right middle and lower lobe bronchiectasis. Bronchoscopy was unremarkable. At thoracotomy bronchoesophageal fistula was divided and the esophageal end was repaired in two layered fashion and reinforced by pediculed parietal pleural flap. Right middle and lower lobectomies were performed. Demonstration of the broncho-esophageal fistula and assessment of the status of the pulmonary parenchyma are important steps prior to surgery.

Abstract
OBJECTIVE To determine whether Behçet's disease (BD), being a systemic vasculitis of unknown aetiology, is associated with hepatitis viruses (HAV, HBV, HCV and HEV). METHODS In addition to 124 patients [male:female (M/F): 73/51], all fulfilling the diagnostic criteria of the International Study Group for BD (1991), 14 patients with systemic necrotizing vasculitis (M/F: 7/7), 47 patients with ankylosing spondylitis (M/F: 36/11) and 51 healthy controls (M/F: 22/29) were also included in this study. Serological markers of four different types of hepatitis (anti-HAV IgM, total anti-HAV, HBsAg, anti-HBs, total anti-HBc, anti-HBc IgM, anti-HCV and anti-HEV) were studied in all cases. RESULTS There was no difference between the groups with respect to HAV, HCV and HEV serologies. Anti-HBs positivity was observed less frequently in BD compared with healthy controls and systemic vasculitis (P<0.05). CONCLUSION Serological evidence of previous HAV, HCV and HEV infections was not significantly different between Behçet's patients and other groups. However, previous HBV infection was found in a significantly lower number of BD patients as compared with healthy controls and systemic vasculitic patients.

Abstract
BACKGROUND Tuberculosis is an important cause of morbidity and mortality in renal transplant recipients, but there are insufficient data regarding the efficacy and complications of therapy and of INH prophylaxis. METHODS This study is a retrospective review of the records of 880 renal transplant recipients in two centers in Turkey. RESULTS Tuberculosis developed in 36 patients (4.1%) at posttransplant 3-111 months, of which 28 were successfully treated. Eight patients (22.2%) died of tuberculosis or complications of anti-tuberculosis therapy. Use of rifampin necessitated a mean of 2-fold increase in the cyclosporine dose, but no allograft rejection occurred due to inadequate cyclosporine levels. Hepatotoxicity developed in eight patients during treatment, two of whom died due to hepatic failure. No risk factor, including age, gender, renal dysfunction, hepatitis C, or past hepatitis B infection, was found to be associated with development of hepatic toxicity. A subgroup of 36 patients with a past history of or radiographic findings suggesting inactive tuberculosis, was considered to be at high risk for developing active disease, of whom 23 were given isoniazid (INH) prophylaxis. None versus 1 of 13 (7.7%) of cases with and without INH prophylaxis, respectively, developed active disease (P>0.05). None of the patients receiving INH had hepatic toxicity or needed modification of cyclosporine dose. CONCLUSIONS These data show that tuberculosis has a high prevalence in transplant recipients, that it can effectively be treated using rifampin-containing antituberculosis drugs with a close follow-up of serum cyclosporine levels, and that INH prophylaxis is safe but more experience is needed to define the target population.

Abstract
The aim of this study, carried out in a specialized centre for chest diseases in Turkey, was to determine the prevalence of glucose intolerance in tuberculosis (TB) and pneumonia so as to assess the specificity of the association of TB with diabetes mellitus. The study group comprised 58 active pulmonary TB patients without any history of diabetes mellitus and the matched control group consisted of 23 community-acquired pneumonia patients. An oral glucose tolerance test (OGTT) was performed at the time of diagnosis and 3 months after the treatment was started in both groups. Glucose intolerance was found in six (10.4%) patients and diabetes mellitus in five (8.6%) patients in the TB group. In the control group, four (17.4%) patients were found to be diabetic and none of them were glucose intolerant. There was no significant difference between the two groups (p > 0.05). There was a higher prevalence of abnormal OGTT results among elderly patients in both groups. OGTT results returned to normal in both the TB and pneumonia groups after treatment. The results suggest that glucose intolerance occurs in the setting of infection and is reversible following adequate antimicrobial treatment.

Abstract
Assessment of bronchodilator responsiveness is currently based on criteria derived from population studies, which provide information on the intrasubject variability of forced expiratory volume in one second (FEV1). These criteria themselves, however, differ from each other; and confusion exists on the best way of expressing reversibility. The aims of this study were to measure spontaneous FEV1 variability individually, and to see its impact on the response to salbutamol. Fifty patients with different types and degrees of chronic airflow obstruction were included in the study. FEV1 was measured twice, with an interval of 20 min, in order to assess spontaneous variability. Spirometry was repeated following salbutamol inhalation, and two estimates of reversibility were obtained using the two FEV1 measurements obtained at baseline. Strong correlations were found between the two estimates, and the mean of the differences between the two reversibility estimates was 65.40 +/- 65.68 ml, when expressed in absolute terms. FEV1 responses to salbutamol were superior to the spontaneous variation in FEV1 in 48 (96%) of the patients. Linear regression analysis revealed that there was a highly significant correlation between the baseline FEV1 and the response to salbutamol (r = 0.50 and 0.43, for the first and the second estimates, respectively). These results suggest that the decision on reversibility should not be based on distinct cut-off levels, but rather should be assessed individually, as intrasubject variability seems to be almost always less than the patient's response to bronchodilators.

Abstract
Rings of canine bronchi were studied in vitro to determine the effects of halothane on the responses of airway smooth muscle to hypercapnia and hypocapnia. Bronchi were first contracted to 50% of maximal active force with acetylcholine (ACh), 5-hydroxytryptamine (5HT), potassium chloride (KCl), or the muscarinic agonist McN-A-343 (McN). The CO2 concentration of the bathing solution was then changed from 6% to either 1% (hypocapnia) or 10% (hypercapnia). In the absence of halothane, changes in CO2 concentration had no significant effect on muscles contracted with ACh. With all other contractile agonists, increasing the CO2 concentration caused bronchial relaxation, while decreasing the CO2 concentration caused contraction. In the presence of 2 MAC halothane, hypocapnia relaxed bronchi contracted with the muscarinic agonists ACh or McN; the responses to hypocapnia of bronchi contracted with KCl and 5HT were not significantly changed by halothane. Halothane had no effect on the responses of the bronchi to hypercapnia. We conclude that airway smooth muscle contracted with cholinergic agonist relaxes in response to hypocapnia when exposed to 2 MAC halothane; this mechanism may contribute to the depression of hypocapnic bronchoconstriction caused by halothane in vivo.

Abstract
Halothane relaxes airway smooth muscles. To test the hypothesis that this relaxation is modulated by airway epithelium, we studied the effects of halothane on isolated second- and third-order canine bronchial rings and second-order canine bronchial segments. Paired rings or segments were examined, with the epithelium removed from one ring or segment of each pair. The bronchial rings were suspended in organ chambers and contracted with 10(-8)-10(-3) M acetylcholine (ACh), 10(-8)-10(-5) M 5-hydroxytryptamine (5HT), or 0.5-16 Hz electrical field stimulation (EFS, 15 V, 0.5-ms pulse duration). The tissue was contracted in the absence of halothane and during exposure to 1 and 2 MAC halothane. The bronchial segments were perfused intraluminally with physiologic salt solution (PSS) and contracted with 10(-6) M carbachol added to the tissue-bath PSS. One or 2 MAC halothane was then added to the perfusate. In the absence of halothane, epithelium removal increased the sensitivity of the bronchial rings to ACh and 5HT but not to EFS. Addition of 1 or 2 MAC halothane to the bathing fluid of the rings with or without epithelium decreased the sensitivity of the rings to ACh and 5HT. One MAC halothane decreased the sensitivity of the rings with and without epithelium to EFS. The decrease in sensitivity caused by halothane was not significantly different in rings with or without epithelium for any method of stimulation. In the bronchial segments, relaxations evoked by 1 or 2 MAC were not different in segments with or without epithelium.(ABSTRACT TRUNCATED AT 250 WORDS)
