Clinical features of lung cancer in patients with connective tissue diseases: a 10-year hospital based study.

BACKGROUND: Connective tissue diseases (CTD) might be associated with various malignancies, and one of the most frequent is lung cancer (LC). Despite our understanding of pathogenesis, this association remains still unclear. The aim of the present study is to describe the clinical characteristics of patients with CTD who developed LC. METHODS: Of 375 successive patients with CTD followed up to University Hospital between 1995 and 2004, 24 patients were diagnosed with LC: 11 (46%) had systemic sclerosis (SSc), 6 (25%) rheumatoid arthritis (RA), 6 (25%) systemic lupus erythematosus (SLE), and 1 (4%) dermatomyositis. We analyzed LC stage, radiological presentation, histological type, patients' smoking status, method of diagnosis, treatment applied, and disease outcome. RESULTS: Average duration of CTD was 13.95 (range 0-30) years. Non-small cell lung cancer (NSCLC) was significantly more frequent than small-cell lung cancer (SCLC). Among patients with NSCLC, 21 patients (85%) presented with stage III or IV. With regard to treatment, 13% patients underwent surgery, 25% chemotherapy, 4% patients combined chemo- and radiotherapy and 58% patients had only supportive therapy. The median survival was 5 months (range 1-96 months). CONCLUSION: The majority of CTD patients who developed LC were diagnosed at advanced stage and had poor survival. Efforts for early detection of LC in CTD patients' group are warranted.

Tuberculosis incidence in elderly in Serbia: key trends in socioeconomic transition.

AIM: To examine tuberculosis incidence rates among the elderly in Central Serbia in 1992-2006 period, which was characterized by socioeconomic crisis and migration of population. METHODS: We analyzed all reported active tuberculosis cases in a 15-year period, especially among patients aged > or =65, according to the Annual Reports of the Institute of Lung Diseases and Tuberculosis in Belgrade and Central Tuberculosis Register. Population estimates with extrapolations were based on 1991 and 2002 census data. RESULTS: Total tuberculosis incidence rates showed a slight but non-significant decreasing trend (P=0.535), and no significant increase was found in patients aged > or =65 years (P=0.064), with an average age-specific incidence rate for the elderly of 64.0 (95% confidence interval, 60.7-67.4). The increase was significant in patients aged > or =70 years (y=49.3549+2.1186x; P=0.001), both in men (y=62.8666+2.3977x; P=0.005) and even more prominently in women (y=39.8240+1.9150x; P<0.001). The proportion of tuberculosis cases in the elderly peaked in 2005, with 35% of all tuberculosis cases. CONCLUSION: High incidence rates and increasing time trend of tuberculosis in the elderly in Central Serbia is a serious problem, especially among those aged 70 years and over, who might present a target group for active case-finding of the disease.

Prevalence of diabetes mellitus (DM) in tuberculosis (TB) patients: clinical and radiologic features in the TB-DM association based on a five-year hospital study.

A previously known association of tuberculosis (TB), now a global emergency, with diabetes mellitus (DM), a chronic disease of increasing prevalence worldwide, has resurfaced. DM is a recognised TB risk factor and M. tuberculosis infection usually disturbs glycoregulation. We aimed to estimate DM prevalence among TB patients and to analyse clinical and radiologic manifestations of TB in this group. The cross-sectional study included 1017 patients discharged with a TB diagnosis from a tertiary level facility in a five-year period. After exclusion of 128 patients with TB sequelae, we selected 889 patients with confirmed active TB, and the final selection led to 88 subjects with both active TB and DM. DM was found in 9.89% of active TB patients. Testing hypotheses for single-sample proportions showed that the prevalence was significantly higher than the prevalence in the general population (p<0.01). The average patient age was 60.47±14.88 years (range: 20-88), while the male/female ratio was 2.26. We found pulmonary TB in 96.3% of the 88 subjects, and extrapulmonary in 3.4%, the latter more frequently in women (p=0.08). Cavities were more frequently found in tobacco smokers compared to non-smokers (p=0.002) and in patients living in rural settings (p=0.002); haemoptysis was detected more frequently in men compared to women (p=0.044). Half of the patients had no fever at all, and only 14.8% had tachycardia. Auscultatory findings were positive in 57 (64.8%) patients. Radiographic changes were atypical in 17/88 (19.3%) patients and included pulmonary bases in seven patients, upper lobe anterior segment, and disseminated miliary pattern in two patients. DM prevalence is significantly higher among TB patients compared to the general population. The mean age of TB patients with DM is significantly higher than expected in TB patients alone. Knowledge of TB clinical and radiologic variations in this group of patients may reduce the delay in TB diagnosis with its clinical and epidemiologic consequences.

Pulmonary and Vertebral Mycobacterium avium Disease in a HIV-negative 71-year-old Man - A Case Report.

Nontuberculous mycobacteria (NTM) caused pulmonary disease is on increase worldwide, especially in countries with decreasing time trend of tuberculosis incidence. NTM skeletal affection is rare. Mycobacterium avium related disease, with still unclear clinical and radiologic features, is in current focus of both clinicians and researchers. An exhausted severely ill 71-year-old man was admitted on emergency due to cough, dyspnea and lumbar back pain to be diagnosed with terminal phase M. avium disease. Three sputum smears were positive for acid fast bacilli and M. avium was identified with hybridization reaction by means of GenoType ® MTBC (Hain). Apart from pulmonary disease, compressive fractures of the 12th thoracic and 1-4th lumbar vertebrae were detected. We found age, chronic alcoholism, previous professional exposure, tobacco smoking, chronic obstructive pulmonary disease and previous tuberculosis as risk factors for NTM disease in the HIV-negative patient. Despite combined antibiotic treatment, disease had lethal outcome. This case report might contribute to clinicians' awareness and improved knowledge on this sort of pathology, and lead to earlier diagnosis with possibly better disease outcome.

Synchronous advanced pulmonary tuberculosis and acute virus myocarditis mimicked Wegener granulomatosis in a 26-year-old man ­ A case report.

Introduction: Tuberculosis patients are rarely asymptomatic. Acute virus myocarditis presents with a wide range of symptoms, from mild dyspnea or chest pain to cardiogenic shock and death. Case Outline: A 26-year-old Caucasian man non-smoker presented with one-week history of lower extremities' swelling. The patient's medical history also revealed a two-day episode of subfebrile temperature with scanty hemoptysis three weeks prior to admission. The episode had not provoked him to seek medical care. Physical examination revealed generalized oedema, and laboratory analysis showed signs of acute renal insufficiency. Enlarged heart and hilar shadows, bilateral massive cavitary pulmonary opacities and pleural effusion were found at chest radiography. Sputum smears were Mycobacteria negative on direct microscopy. Electrocardiogram changes and echocardiography were suggestive of acute myocarditis with dilated cardiomyopathy. IgM titer to adenovirus was positive. Under diuretics, angiotensin-converting-enzyme inhibitor, beta-blocker, antibiotics and bed rest, fast heart compensation and renal function repair were achieved. Radiographic pulmonary changes promptly regressed except for a cavity in the right upper lobe. Bronchial aspirate from the affected lobe was Mycobacteria positive on direct microscopy and culture positive for Mycobacterium tuberculosis. Standard anti-tuberculosis drug regimen led to recovery. Conclusion: In the unusual common existence of two diseases whose presentation initially mimicked Wegener's granulomatosis, acute dilated cardiomyopathy contributed to pulmonary tuberculosis detection. To prevent diagnostic delay in tuberculosis, further efforts in population education are necessary together with continual medical education

Drug induced lung disease--amiodarone in focus.

More than 380 medications are known to cause pulmonary toxicity. Selected drugs that are important causes of pulmonary toxicity fall into the following classes: cytotoxic, cardiovascular, anti-inflammatory, antimicrobial, illicit drugs, miscellaneous. The adverse reactions can involve the pulmonary parenchyma, pleura, the airways, pulmonary vascular system, and mediastinum. Drug-induced lung diseases have no pathognomonic clinical, laboratory, physical, radiographic or histological findings. A drug-induced lung disease is usually considered a diagnosis of exclusion of other diseases. The diagnosis of drug-mediated pulmonary toxicity is usually made based on clinical findings. In general, laboratory analyses do not help in establishing the diagnosis. High-resolution computed tomography scanning is more sensitive than chest radiography for defining radiographic abnormalities. The treatment of drug-induced lung disease consists of immediate discontinuation of the offending drug and appropriate management of the pulmonary symptoms. Glucocorticoids have been associated with rapid improvement in gas exchange and reversal of radiographic abnormalities. Before starting any medication, patients should be educated about the potential adverse effects of the drug. Amiodarone is an antiarrhythmic agent used in the treatment of many types of tachyarrhythmia. Amiodarone-caused pulmonary toxicity is a well-known side effect (complication) of this medication. The incidence of amiodarone-induced lung disease is approximately 5-7%.

Illness perception in tuberculosis by implementation of the Brief Illness Perception Questionnaire - a TBNET study.

How patients relate to the experience of their illness has a direct impact over their behavior. We aimed to assess illness perception in patients with pulmonary tuberculosis (TB) by means of the Brief Illness Perception Questionnaire (BIPQ) in correlation with patients' demographic features and clinical TB score. Our observational questionnaire based study included series of consecutive TB patients enrolled in several countries from October 2008 to January 2011 with 167 valid questionnaires analyzed. Each BIPQ item assessed one dimension of illness perceptions like the consequences, timeline, personal control, treatment control, identity, coherence, emotional representation and concern. An open question referred to the main causes of TB in each patient's opinion. The over-all BIPQ score (36.25 ± 11.054) was in concordance with the clinical TB score (p ≤ 0.001). TB patients believed in the treatment (the highest item-related score for treatment control) but were unsure about the illness identity. Illness understanding and the clinical TB score were negatively correlated (p < 0.01). Only 25% of the participants stated bacteria or TB contact as the first ranked cause of the illness. For routine clinical practice implementation of the BIPQ is convenient for obtaining fast and easy assessment of illness perception with potential utility in intervention design. This time saving effective personalized approach may improve communication with TB patients and contribute to better behavioral strategies in disease control.

Time trend and clinical pattern of extrapulmonary tuberculosis in Serbia, 1993-2007.

BACKGROUND/AIM: Increased incidence of extrapulmonary tuberculosis (XPTB) is reported worldwide. Serbia is a country in socio-economic transition period with low-middle HIV prevalence and intermediate-to-low tuberculosis (TB) incidence rate, 100% directly observed treatment (DOT) coverage, and mandatory BCGC vaccination at birth. The aim of the study was to examine the incidence trend and clinical features of XPTB in Serbia during a 15-year period. METHODS: This retrospective observational study included XPTB cases diagnosed in the period between 1st January 1993 and 31st Decembre 2007, according to the reports of the National Referral Institute of Lung Diseases and Tuberculosis in Belgrade and Central Tuberculosis Register. Population estimates with extrapolations were based on 1991 and 2002 census data. RESULTS: While the overall TB incidence rate showed a slight, not significant decreasing trend (p = 0.535), a significant increase was found for XPTB (y = 1.7996 + 0.089x; R2 = 0.4141; p = 0.01). A total of 2,858 XPTB cases (newly diagnosed and 10% relapses) gave an average age specific incidence rate of 2.51/100,000 population (95% confidence interval, SD = 0.6182) with 8.9% annual increase. The male-to-female ratio was 0.54. Lymph nodes were most frequently affected site (48.5%) followed by genitourinary (20.5%), pleural (12%), and osseo-arthicular (10.3%) TB. Treatment outcome was successful in 88.29% of patients (cured and completed), 3.64% died, 5.18% interrupted, 0.57% displaced, and 2.3% unknown. CONCLUSION: Increasing trend of XPTB incidence rate may be a result of increased morbidity due to still present risk factors, possible higher detection rate in Serbia and better notification. A high coverage of newborns with BCG vaccination at birth might contribute to a decreased number and rare XPTB cases in children.

Symptoms of anxiety and depression in patients with chronic obstructive pulmonary disease.

INTRODUCTION: Despite the prevalence and importance of anxiety and depressive symptoms in chronic obstructive pulmonary disease (COPD) patients, procedures for routine screening in therapeutic protocols are not commonly used. OBJECTIVE: to assess the symptoms of anxiety and depression in COPD patients and to evaluate their relation to patients' demographic parameters and clinical characteristics. METHODS: The research included 40 COPD patients, treated at the Institute of Lung Diseases and Tuberculosis, Clinical Centre Serbia in Belgrade, from November 2010 to February 2011. Study data were assessed by the questionnaire designed for the purposes of the present study together with Hamilton Anxiety Rating Scale (HARS) and Hamilton Depression Rating Scale (HDRS). RESULTS: Mean HARS score was 10.7 (SD=6.5) (22.5% subjects scored > or = 17) and mean HDRS score was 10.7 (SD=8.2) (20.0% subjects scored > or = 17). Depression was significantly higher in women (Z=-1.971: p=0.049). Lower value of forced expiratory volume in one second (FEV1) correlated with higher HDRS score (p=-0.321; p=0.042). The incidence of anxiety and depression symptoms is higher in patients with more hospitalizations and longer hospital stay. CONCLUSION: The prevalence and importance of anxiety and depressive symptoms in COPD patients require implementation of a specific questionnaire as the procedure for routine screening in order to detect affective symptoms early and to prevent the progression.

Asthma mortality in Serbia: a 30-year analysis.

INTRODUCTION: The asthma mortality pattern differs among countries. No published evidence is currently available on asthma mortality in a European low-middle-income country in socioeconomic transition. We analyzed the trend of asthma mortality rate in Serbia during the period 1980-2009. MATERIALS AND METHODOLOGY: a descriptive study; source of data: Republic of Serbia Institute of Statistics Death Registry. We analyzed asthma mortality data in the total population, including gender specific analysis, and in the selected ≥ 5-34 year age group. The International Classification of Diseases codes for asthma 493 (1980-1996) and J45 + J46 (1997-2009) were included. Population estimates were based on 1991 and 2002 census data, with extrapolation. RESULTS: The over-all average mortality rate was 7.27 ± 2.14/100,000 inhabitants. The mortality rate peaked in 1981 at 11.3/100,000 but was 4.45/100,000 in the last year of analysis. While both overall mortality rate, as well as gender specific rates, showed clear decreases over the observed 30-year period (average absolute annual decrease of 0.195/100,000 inhabitants, 0.241/100,000 men and 0.149/100,000 women; p < 0.001) with corresponding relative annual decreases of 2.9% for the whole population, 3.0% for men and 2.8% for women, a stable trend of the rate was found in the age group ≥ 5-34 years. Male-to-female ratio was 1.59 ± 0.186, on average and it showed a stable trend over the observed period. CONCLUSION: Although the failure of the health care system during the socioeconomic crisis of the 1990s might have transiently affected asthma mortality rates, the overall mortality rate for the disease shows a favorable decreasing trend.

Clinical and radiographic features of sarcoidosis in menopausal women--the impact on therapeutic approach and prognosis.

BACKGROUND/AIM: Sarcoidosis is a multisystemic granulomatous disease of unknown etiology. The aim of the study was to determine are there significant differences in clinical manifestations, radiographic and lung function findings and therapeutic approach in menopausal female sarcoidosis pa-tients compared to premenopausal ones. METHODS: Seventy seven Caucasian women (average age 43.71 years, range 38-54) with sarcoidosis diagnosed at the University Hospital from January to October 2006, were included in the study. They were divided into two groups according to their menstrual period status. The group I included 42 women with normal menstrual cycle, while the group II included 35 menopausal women (either spontaneous or after hysterectomy). The patients were not under hormonal therapy. RESULTS: We found significantly higher proportion of the first radiographic stage (66.7% vs 34.2%, p < 0.05) and acute form of sarcoidosis (57.2% vs 17.1%; p < 0.01) in the group I in relation to the group II. Extrapulmonary sarcoidosis was more frequent in the group II than in the group I (p < 0.01). Disturbances of lung ventilation were registered in 50.8% of all the patients, and decrease of one or both of diffusion parameters was found in 63.6%, but without significant differences between the groups (p > 0.05). Hypercalciuria was found in 19.1% of the patients in the group I and 42.8% of the patient in the group II (p < 0.05). A difference in the therapy approach was also found to be significant with methotrexate more frequently applied in the group II than in the group I (p < 0.01). CONCLUSION: Menopausal women with sarcoidosis may represent a group of patients that requires special attention in diagnostic procedure, therapeutic approach and follow-up, to prevent unfavourable course of the disease. Attention should be particularly focused on the detection of extrapulmonary sites involvement in this group of the patients. Further prospective studies are needed to reveal the role of hormones, and especially plasma estrogen level in sarcoidosis appearance.

Tuberculous synovitis of the knee in a 65-year-old man.

INTRODUCTION: Tuberculous (TB) synovitis is a rare, treatable, potentially lethal form of extrapulmonary TB resulting from massive lymphohematogenous dissemination of Mycobacterium tuberculosis (M. tuberculosis). We presented a case of TB synovitis of the knee in a Caucasian HIV-negative man from Romania, a high TB incidence country. CASE REPORT: A 65-year old man presented with cough, high fever, mild wheezing, and swelling of the left knee. Chest radiography was normal. Sputum smears were Acid Fast Bacilli negative and Lowenstein-Jensen (L-J) culture negative for M. tuberculosis. Tuberculin skin test was negative. Respiratory symptoms disappeared in a week under antibiotics. Positive L-J cultures of knee punctation and favourable treatment outcome following standardized antituberculous treatment regimen confirmed the diagnosis of specific synovitis, which was also demonstrated by Magnetic Resonance Imaging (MRI). CONCLUSION: Tuberculous synovitis is important differencial diagnosis in patients with arthropathies and risk factors for TB in all the countries and all patients' ages even when tuberculin skin test is negative.

Pulmonary rehabilitation in elderly patients with chronic obstructive pulmonary disease.

Elderly patients with chronic obstructive pulmonary disease (COPD), neglected in terms of pulmonary rehabilitation some decades ago, have nowadays evidence-based recommendations to attend it. There are no serious limitations excepting the locomotor handicap (neurological and musculoskeletal disability), severe cardiovascular and cognitive impairment. Multiple outcomes are expected to show up, as improvement of cardiovascular fitness and exercise capacity, relieving symptoms as dyspnoea, depression and anxiety. Meeting people like them on pulmonary rehabilitation premises, with same limitations and life beliefs, benefiting of group support and staff encouragement, elderly patients with COPD will find out that a pulmonary rehabilitation course might be both pleasant and useful, despite of distance of journey and physical training.
