Objective: To investigate the prevalence of infection, disease and eventual institutional outbreak of tuberculosis in a psychiatric hospital using the PPD test, as well as testing for mycobacteria in material collected from the respiratory tree and using molecular tracking technique based on insertion sequence 6110 (IS6110). Methods: Between February and August of 2002, PPD tests were given to 74 inpatients and 31 staff members at a psychiatric hospital in the city of Rio Verde, located in the state of Goiás, Brazil. In addition, respiratory tree material collected from the inpatients was submitted to testing for Mycobacterium tuberculosis. Results: Among the patients analyzed, mycobacteria were isolated from five (6.8%): four identified as M. tuberculosis and one as M. chelonae. The M. tuberculosis isolates were sensitive to isoniazid and rifampicin, and, when submitted to the restriction fragment length polymorphism/IS6110 technique, presented unique genetic profiles, totally distinct from one another, suggesting that all of the tuberculosis cases were due to endogenous reactivation. It was not possible to characterize this group of cases as an institutional outbreak. Performing the two-step tuberculin test in the patients, the infection rates were 23% and 31%, compared with 42% among staff members, who were submitted to the one-step test. Conclusion: The results indicate a high incidence of tuberculosis infection among inpatients and hospital staff, as well as a high occurrence of the disease among inpatients.

Objective: To describe the patient profile, mortality rates, the accuracy of prognostic scores, and mortality-associated factors in patients with community-acquired pneumonia (CAP) in a general hospital in Brazil. Methods: This was a cohort study involving patients with a clinical and laboratory diagnosis of CAP and requiring admission to a public hospital in the interior of Brazil between March 2014 and April 2015. We performed multivariate analysis using a Poisson regression model with robust variance to identify factors associated with in-hospital mortality. Results: We included 304 patients. Approximately 70% of the patients were classified as severely ill on the basis of the severity criteria used. The mortality rate was 15.5%, and the ICU admission rate was 29.3%. After multivariate analysis, the factors associated with in-hospital mortality were need for mechanical ventilation (OR: 3.60; 95% CI: 1.85-7.47); a Charlson Comorbidity Index score > 3 (OR: 1.30; 95% CI: 1.18-1.43); and a mental Confusion, Urea, Respiratory rate, Blood pressure, and age > 65 years (CURB-65) score > 2 (OR: 1.46; 95% CI: 1.09-1.98). The mean time from patient arrival at the emergency room to initiation of antibiotic therapy was 10 h. Conclusions: The in-hospital mortality rate of 15.5% and the need for ICU admission in almost one third of the patients reflect the major impact of CAP on patients and the health care system. Individuals with a high burden of comorbidities, a high CURB-65 score, and a need for mechanical ventilation had a worse prognosis. Measures to reduce the time to initiation of antibiotic therapy may result in better outcomes in this group of patients.

Streptococcus pneumoniae resistance to penicillin was studied in two hospitals in Caxias do Sul, Rio Grande do Sul, Brazil, between May 1998 and November 2001. From the 176 strains of invasive Streptococcus pneumoniae that were identified, 2.28% (CI 0.62-5.74) presented intermediate resistance, and 3.42% (CI 1.26-7.31) presented high-level resistance. Conclusion was that the use of penicillin in Caxias do Sul was still justified as treatment of pneumococcal pneumonia, differently from other centers where the penicillin was replaced by other antibiotics. These results confirm the statement of IDSA (Infectious Diseases Society of America) guideline for the management of community-acquired pneumonia in adults, that the choice of antimicrobial drug to treat pneumococcal pneumonia should be guided by local or regional prevalence of resistance to penicillin.

Objective: Epidemiologic survey of respiratory diseases that cause hospital admissions at the Internal Medicine Service, Hospital Geral de Caxias do Sul (SCM-HG), a tertiary university hospital in the State of Rio Grande do Sul, Southern Brazil. Patients and methods: Retrospective study conducted at SCM-HG between November 1998 and November 1999. Data were obtained from medical records and included: a) major admission cause; b) associated diseases; c) sazonal variability; d) hospitalization length; e) mortality. Results: There were 1,200 admissions at SCM-HG, 228 (19%) caused by a respiratory disease. COPD (41.3%), pneumonias (29.8%) and bronchial asthma (9.6%) were the most prevalent. Fifty subjects (21.9%) presented comorbidity: cardiac failure (7.7%), systemic arterial hypertension (6.4%) and diabetes mellitus (4.4%). Pneumonias predominated between September and November, bronchial asthma frequency raised in October and November, and COPD prevailed from May to November. The admissions had an average duration of 10.4 ± 10 days. Twenty-six (11.4%) patients died. Conclusions: 1) Respiratory diseases were responsible for approximately 1/5 of the admissions. 2) COPD patients represented the biggest quota of admissions. 3) Patients with respiratory diseases stayed for a long time as compared with the others hospitalized patients (10.4 versus 7.7 days). 4) COPD, pneumonias and bronchial asthma behaved as expected regarding sazonal variability.

Objective: To evaluate cases of tuberculosis occurring in the Entorno region of the state of Goiás but reported in the Federal District (FD) and to analyze the influence that this has on the effectiveness of the local tuberculosis control program, as well as on the socioeconomic and demographic data related to tuberculosis incidence rates. Methods: Rates of tuberculosis incidence, cure, noncompliance, treatment failure, mortality and referral, as well as socioeconomic and demographic data, were reviewed for patients from ten cities in Goiás. Results: From 2000 to 2004 in the cities under study, 714 new cases of tuberculosis were reported, 436 (61.0%) of which were treated in the FD, and therefore, were not included in the Goiás database. Among patients treated only in Goiás, the mean incidence of tuberculosis ranged from 4.40 to 10.02/100,000 inhabitants. When those treated in the FD were included, the incidence significantly increased, ranging from 15.16 to 20.54/100,000 inhabitants (p < 0.001). The rate at which contacts of tuberculosis patients were investigated was low, and treatment outcomes were unsatisfactory in Goiás and in the DF. Socioeconomic and demographic data were consistent with the tuberculosis incidence. Conclusion: The number of tuberculosis patients treated in the city in which they reside was lower than expected. Treatment in another city might compromise tuberculosis control. The recalculated tuberculosis incidence is consistent with the socioeconomic and demographic profile of the region. A federal surveillance system can be efficiently optimized, improving the control of this disease.

Objective: To determine the prevalence and characteristics of smoking among inpatients at a university hospital, as well as to evaluate their motivation, interest, and need for help in quitting smoking. Methods: A prospective study involving inpatients treated between May of 2008 and April of 2009 on the cardiovascular disease wards at the Antonio Pedro University Hospital, located in the city of Niterói, Brazil. All inpatients were asked to complete a questionnaire designed to collect data regarding demographics, reasons for admission, and smoking status. The smokers also responded to additional questions regarding their smoking habits. The level of nicotine dependence was determined with the Fagerström Test for Nicotine Dependence. Results: Of the 136 inpatients who participated in the study, 68 (50.0%) were male. The mean age was 60.7 years. The prevalence of smoking was 13.2%. Among the 49 patients with coronary disease, 36 (73.5%) were smokers or former smokers. The majority of the patients presented with a high level of nicotine dependence and reported withdrawal symptoms during hospitalization. Although most smokers were motivated to quit smoking, they admitted that they needed help to do so. Conclusions: Because smoking is forbidden in the hospital environment and most inpatients who smoke are highly motivated to quit, health professionals should view the hospitalization period as an opportunity to promote smoking cessation.

Objective: To determine the main causes of hemoptysis and to classify this symptom, in terms of the amount of blood expectorated, in patients hospitalized at a referral hospital for pulmonology. Methods: The study included 50 patients with hemoptysis admitted to the pulmonology ward of a general hospital in the city of Recife, Brazil, between July of 2005 and February of 2006. The data of interest were analyzed and compared with those in the literature. Results: The most common cause of hemoptysis was infection-in 39 patients (78%)-mostly related to tuberculosis sequelae or active tuberculosis. Regarding the severity of hemoptysis, moderate hemoptysis, diagnosed in 28 patients (56%), was the most common. Conclusions: Our results suggest that all patients who present with hemoptysis should be investigated for infection.

Objective: To evaluate the use of venous thromboembolism (VTE) prophylaxis in a general hospital. Methods: A cross-sectional cohort study at the Hospital Nossa Senhora da Conceição, located in the city of Porto Alegre, Brazil, involving a random sample of patients admitted between October of 2008 and February of 2009. We included patients over 18 years of age and hospitalized for more than 48 h. The exclusion criteria were anticoagulant use, pregnancy, puerperium, and a history of thromboembolic disease. The adequacy of prophylaxis was evaluated in accordance with a protocol created by the Hospital and principally based on the American College of Chest Physicians guidelines, eighth edition. Results: We included 262 patients. The mean age was 59.1 ± 16.6 years. The most common risk factors were immobilization (in 70.6%), infection (in 44.3%), cancer (in 27.5%), obesity (in 23.3%), and major surgery (in 14.1%). The risk of VTE was classified as high and moderate in 143 (54.6%) and 117 (44.7%) of the patients, respectively. Overall, 46.2% of the patients received adequate prophylaxis, 25% of those with ≥ three risk factors for VTE and 18% of those with cancer, the differences between these last two groups and their counterparts (patients with < three risk factors and those without cancer) being statistically significant (p < 0.001 for both). Conclusions: Our data reveal that nearly all patients at our hospital were at risk for VTE, and that less than half received adequate VTE prophylaxis, which is in agreement with the literature. It is surprising that inadequate prophylaxis is more common in high-risk patients.

Objective: To evaluate the experience in diagnosing and treating malignant pleural mesothelioma (MPM) accumulated over 5 years in a tertiary public hospital. Methods: The medical charts of the patients diagnosed with MPM between January of 2000 and February of 2005 were evaluated retrospectively. Results: Of the 17 patients analyzed, 14 were male and 3 were female. The mean age was 54.1 years (range, 13-75 years). The biopsy specimens for histopathological examination were obtained through thoracoscopy in 9 patients (53%), Cope needle in 5 (29.5%), and open pleural biopsy in 3 (17.5%). The following histological types were identified: epithelial, in 14 patients (82%); sarcomatoid, in 1 (6%); and biphasic, in 2 (12%). The therapeutic approaches used were as follows: multimodal (pleuropneumonectomy and adjuvant radiotherapy and chemotherapy) in 6 patients (35%); chemotherapy and radiotherapy in 6 (35%); radiotherapy alone in 3 (17.5%); and chemotherapy alone in 2 (12%). The mean survival was 11 months (range, 1-26 months). Conclusions: In the cases studied, an integrated multidisciplinary approach was used, and a highly complex hospital infrastructure was available for the diagnosis and treatment of MPM, as recommended in the literature. However, the mean survival was only 11 months, reflecting the aggressiveness of the disease.

Patients with active tuberculosis (Tb) can be admitted to hospital due to other health problems, Tb not being the admission diagnosis. In this study, the authors analyzed 141 inpatients with Tb, notified to the São Paulo Hospital Central Control of Infectious Diseases, during the period of august, 1999 to April, 2001, trying to identify causes of admission, risk factors, and duration of hospitalization. Of the total number of patients, 63% were male and 37% female, mean age being 38 years-old. 28% were smokers, 23% were alcoholics, and 17% were drug addicts. 23% of them reported previous Tb. 42% were HIV positive. 54.6% of the patients presented pulmonary tuberculosis and 67.5% of them had positive sputum. 22% of the patients had side effects to Tb treatment during hospitalization, drug-induced hepatitis (65.7%) and gastric intolerance (25.7%) being the most frequent. 8.5% of the patients required intensive care, staying there for 11 days, and 54% of the patients stayed at an infirmary with respiratory isolation. 17.7% of the patients died in hospital and 52% due to Tb. The patients were hospitalized for 29 days and isolated for 18 days. Drug addicts and smokers patients had longer hospital stays. HIV positive patients who had positive sputum had the same hospitalization period as others.

Objective: To describe the epidemiological monitoring of exposure to tuberculosis in a hospital environment and to analyze the profile of the disease in a general teaching hospital. Methods: A descriptive and retrospective study of tuberculosis cases diagnosed between 2000 and 2006, with the determination of indicators of morbidity and mortality, which were compared with the general population of patients treated at the hospital and with the hospital employees who developed active tuberculosis. Results: There were 763 patients who were treated for active tuberculosis (mean, 109 patients/year), 481 (63.1%) of whom were male. Most of the patients were in the 30-59 year age bracket. Tuberculosis that was exclusively pulmonary or extrapulmonary predominated. However, among the hospitalized patients, the combination of pulmonary and extrapulmonary tuberculosis, as well as exclusively noninfectious tuberculosis, predominated. Comorbidities were more prevalent among the hospitalized patients and among those who evolved to death. Only 52.8% of the cases treated at the hospital were reported. The overall hospital indicators showed longer length of hospital stay and greater mortality among the patients with tuberculosis. The incidence and prevalence show that there was a high risk of exposure to tuberculosis in the hospital during the period studied. Conclusions: The proposed indicators can potentially help standardize epidemiological monitoring procedures for nosocomial tuberculosis, and the epidemiological profile described in this study can contribute to a better understanding of the situation of tuberculosis in Brazil.

Objective: To determine the frequency of smoking among hospitalized patients in a general hospital, and to evaluate their profile. Methods: A random representative sample of 111 patients, classified as nonsmokers, former smokers or smokers, was evaluated. The smokers were submitted to the Fagerström test and measurement of expired carbon monoxide. Expired carbon monoxide higher than 6 ppm was considered a significant indicator of recent smoking. Results: Of the 111 patients in the sample, 60 (54%) were female. The mean age was 70 years. Of the 111 patients, 56 (51%) had never smoked, 36 (32%) were former smokers, and 19 (17%) were smokers. All of the smokers were male. The smokers were younger (58 ± 17 years) than the nonsmokers (68 ± 12 years) and the former smokers (73 ± 14 years)-ANOVA: F = 6.57 (p = 0.002). Among the smokers, the mean tobacco intake was 43 pack-years and the mean Fagerström score was 5.0. Of the 19 smokers, 11 (58%) had respiratory symptoms and 3 had withdrawal symptoms. The mean expired carbon monoxide in the smokers was 5.0 ppm. Expired carbon monoxide levels were higher than 6 ppm in 8 (42%) of the smokers. There was a higher prevalence of smokers in some wards: 70% of all smokers were hospitalized on only five wards. Conclusions: In a large tertiary hospital, 17% of the hospitalized patients were smokers, and 7% had smoked within the last 8 h. The smokers were younger men, hospitalized on specific wards.

Objective: To analyze the complications related to flexible bronchoscopy (FB) and its collection procedures in outpatients and inpatients with various lung and airway diseases treated at a university hospital. Methods: This was a retrospective analysis of complications occurring during or within 2 h after FB performed between January of 2012 and December of 2013, as recorded in the database of the respiratory endoscopy department of a hospital complex in the city of São Paulo, Brazil. Results: We analyzed 3,473 FBs. Complications occurred in 185 procedures (5.3%): moderate to severe bleeding, in 2.2%; pneumothorax, in 0.7%; severe bronchospasm, in 0.8%; general complications (hypoxemia, psychomotor agitation, arrhythmias, vomiting, or hypotension), in 1.6%; and cardiopulmonary arrest, in 0.03%. There were no deaths related to the procedures. Specifically, among the 1,728 patients undergoing biopsy, bronchial brushing, or fine-needle aspiration biopsy, bleeding occurred in 75 (4.3%). Among the 1,191 patients undergoing transbronchial biopsy, severe pneumothorax (requiring chest tube drainage) occurred in 24 (2.0%). Conclusions: In our patient sample, FB proved to be a safe method with a low rate of complications. Appropriate continuing training of specialist doctors and nursing staff, as well as the development of standardized care protocols, are important for maintaining those standards.

Objective: To describe the reasons smokers give for seeking smoking cessation treatment, correlating those reasons with sociodemographic characteristics, clinical data, stage of readiness to change, and severity of nicotine dependence. Methods: Between February of 2008 and February of 2009, we evaluated 53 smokers who were naive to smoking cessation treatment and sought such treatment at the psychoactive substance abuse outpatient clinic of a university general hospital. The instruments used in the study were as follows: a form for the collection of sociodemographic and clinical data; the Fagerström Test for Nicotine Dependence; the University of Rhode Island Change Assessment scale; and a questionnaire on the smoking habit. Results: The sample comprised 34 women and 19 men, with a mean age of 48.1 years. Most of the participants had less than 8 years of schooling, had tobacco-related diseases, started smoking during adolescence, had smoked for more than 20 years, and had high nicotine dependence. The decision to quit smoking was mainly influenced by advice from family members, and the decision to seek specialized smoking cessation treatment was influenced by physicians. Most of the men were in the contemplation stage of change, whereas the women tended to have a more balanced distribution of the stages (p = 0.007). The women had attempted to quit smoking more often than had the men (p = 0.017) and also had a higher level of nicotine dependence (p = 0.053). Conclusions: The findings of this study highlight the role of health professionals in the approach to smoking cessation and suggest the importance of interventions that are more targeted, in view of the differences between men and women.

Objective: To implement community-acquired pneumonia (CAP) guidelines at a public hospital in Brazil and to evaluate the impact of these guidelines on health care quality. Methods: A quasi-experimental study, with a before-and-after design, involving adult patients diagnosed with CAP and hospitalized between July of 2007 and October of 2008 in the general ward of the Marília School of Medicine Hospital das Clínicas, located in the city of Marília, Brazil. Results: During the study period, 68 patients were diagnosed with CAP: 48 before the implementation of the guidelines and 20 after their implementation. After the implementation of the guidelines, 85% of the cases were treated in accordance with the guidelines, and there was a significant increase in the use of antibiotic therapy for atypical bacteria in patients with severe CAP (6.3% vs. 75.0%; p < 0.001). Comparing the pre-implementation and post-implementation periods, we observed a trend toward a decrease in the mortality (35.4% vs. 15.0%; p = 0.09) and toward an increase in the recording of SpO2 in the medical charts of the patients (18% vs. 30%; p = 0.42). During the study period, the degree of severity was not recorded on the medical charts of most patients. In addition, the initiation of antibiotic therapy followed a pre-established schedule, regardless of the severity of the infection. Conclusions: This study showed that, although the development and implementation of CAP guidelines promoted the optimization of the treatment, there were no significant differences regarding the assessment of severity, SpO2 recording, or the initiation of antibiotic therapy. Therefore, strategies that are more effective are needed in order to modify variables related to the work of physicians and nurses.

Objective: To determine the prevalence of smoking and the frequency of smoking cessation counseling among patients at a university hospital, as well as to compare smokers and former smokers in terms of smoking history. Methods: A cross-sectional study involving 629 patients at the Federal University of Paraná Hospital de Clínicas, located in the city of Curitiba, Brazil. Results: Of the 629 patients, 206 (32.7%) were male, 76 (12.1%) were smokers, 179 (28.5%) were former smokers, and 374 (59.5%) were nonsmokers. The mean age of the patients was 49.9 ± 15.0 years (range, 18-84 years). Of the 76 smokers and 179 former smokers, 72 (94.7%) and 166 (92.7%), respectively, were questioned about tobacco use. Smoking history and degree of nicotine dependence were higher among the former smokers (p = 0.0292 and p = 0.0125, respectively). Gender, age at smoking initiation, physician inquiry about tobacco use, and smoking cessation counseling were comparable between the two groups. The smoking cessation rate was 0.70. The prevalence of heavy smoking varied by gender and by age bracket, being higher in males and in the 41-70 year age bracket. Conclusions: The smoking prevalence in this group of patients was lower than that reported for patients at another university hospital, for adults in Curitiba, and for adults in Brazil. The smoking cessation rate was higher in these patients than in the general population of Curitiba. Smokers and former smokers differed regarding age, smoking history, and degree of nicotine dependence. Heavy smoking and a moderate or high degree of nicotine dependence were not obstacles to smoking cessation.

Objectives: The purpose of this study is to establish the prevalence of pulmonary thromboembolism (PTE) in autopsies and its rate of antemortem suspicion at Hospital de Clínicas de Porto Alegre (HCPA). Design: Cohort study with historical data. Setting: School hospital with 728 beds. Patients and methods: The adult autopsy reports were studied from 1985 to 1995 as well as the records of patients whose autopsies diagnosed PTE. Antemortem suspicion of PTE was considered from explicit notes on patients records, from requests of lung scan, or from full anticoagulation. Results: In the period mentioned, 9,607 deaths occurred, and 767 (7.98%) autopsies were performed. Significant PTE (> 1 pulmonary subsegment) in 30 (3.9%) patients. In 3 (10%) patients, PTE was considered the effective cause of death. Clinic suspicion was present in 5 (16.6%) patients; in 25 (83.4%) patients, there were only postmortem findings. Conclusion: PTE rates in autopsies were similar to those found in international literature. The rates of clinical suspicion were half of the ones mentioned in school hospitals in the United States and Europe. PTE was subsuspected in life in patients hospitalized at HCPA.

Objective: Evaluate the efficacy of the ampicillin-quinolone association in the treatment of severe community-acquired pneumonia. Design: Open, prospective study carried out at the Emergency room of the Hospital Universitário da Universidade Federal de Juiz de Fora. Patients and methods: From March 1994 to September 1995, the authors studied 23 patients with fever and with at least three of the following symptoms: cough, purulent sputum, pleuritic thoracic pain, leukocytosis or leukopenia, and a chest radiological examination showing infiltrations compatible with pneumonia diagnosis. The patient diagnosis would be severe pneumonia if he met the criteria of severe sepsis as established by the American College of Chest Physicians and by the Society of Critical Care Medicine. Results: 23 patients were studied. One was excluded after having a pulmonary tuberculosis diagnosis; 21 patients were considered cured and one died. Adverse drug effects occurred in one patient who presented a mild pharmacodermia. Conclusion: Ampicillin-quinolone is efficient in the treatment of severe community-acquired pneumonia.
