Central nervous system (CNS) tuberculosis includes three clinical entities: tuberculous meningitis, intracranial tuberculoma, and spinal tuberculous arachnoiditis. All three categories are encountered frequently in regions of the world where the incidence of TB is high. Meningeal tuberculosis is a medical emergency: it is the most severe, lethal and disabling form of tuberculosis. Early diagnosis and treatment can be lifesaving. Even, in developed countries the diagnosis of tuberculous meningitis is difficult, frequently delayed or missed, and is often not microbiologically confirmed...

Chronic obstructive pulmonary disease (COPD) is a respiratory disease that has a major impact worldwide. The currently-available drugs mainly focus on relieving the symptoms of COPD patients. However, in the latter stages of the disease, the airways become largely obstructed and lung parenchyma becomes destructed due to underlying inflammation. The inappropriate repair of lung tissue after injury may contribute to the development of disease. Novel regenerative therapeutic approaches have been investigated with the aim of repairing or replacing the injured functional structures of the respiratory system...

Background and Purpose: Although incidence rates vary, infectious, autoimmune, and neoplastic diseases can all cause chronic and subacute meningitis (CSM). We report a Latin-American, single center, CSM case series, analyzing the main clinical characteristics as well as ancillary diagnostic methods differentiating neoplastic from non-neoplastic etiologies. Methods: Retrospective review of CSM cases from a single center in Buenos Aires, Argentina. Results: Seventy patients with CSM diagnosis were identified, 49 with neoplastic and 21 with non-neoplastic meningitis...

Previously we showed that alveolar macrophages (AMs) from patients with chronic beryllium disease (CBD) and beryllium sensitization (BeS) demonstrated significantly greater cell surface CD16 (encoded by the FCGR3A gene) than controls. We hypothesized that these differences were related to polymorphisms in the FCGR3A gene. This study was to determine the association between FCGR3A polymorphisms in CBD, BeS versus controls as well as clinical data, providing potential information about disease pathogenesis, risk, and activity...

BACKGROUND: The prevalence of asthma and chronic obstructive pulmonary disease (COPD) has risen markedly over the last decades and is reaching epidemic proportions. However, underlying molecular mechanisms are not fully understood, hampering the urgently needed development of approaches to prevent these diseases. It is well established from epidemiological studies that prenatal exposure to cigarette smoke is one of the main risk factors for aberrant lung function development or reduced fetal growth, but also for the development of asthma and possibly COPD later in life...

Infection with the hepatitis C virus (HCV) has adverse liver, kidney, and cardiovascular consequences in patients with chronic kidney disease (CKD), including those on dialysis therapy and in those with a kidney transplant. Since the publication of the original Kidney Disease: Improving Global Outcomes (KDIGO) HCV Guideline in 2008, major advances in HCV management, particularly with the advent of direct-acting antiviral therapies, have now made the cure of HCV possible in CKD patients. In addition, diagnostic techniques have evolved to enable the noninvasive diagnosis of liver fibrosis...

NEW FINDINGS: What is the central question of this study? Cigarette smoking is associated with increased oxidative stress and apoptosis in lungs. Our aim was to examine the effect of cigarette smoke on cell death, oxidative damage, expression of heat shock proteins (HSPs) and activation of mitogen-activated protein kinases (MAPKs) in A549 alveolar epithelial cells. What is the main finding and its importance? Cigarette smoke induces cytotoxicity and oxidative damage to A549 cells, increases expression of different HSPs and activates MAPK signaling pathways...

Bronchiectasis is a chronic respiratory disorder characterized by persistent productive cough and recurrent chest infections secondary to permanent structural airway damage. The current treatment strategies for this debilitating disorder are limited to prompt antibiotic treatment of infective exacerbations and regular airway clearance techniques. Despite its high morbidity and associated mortality across all age groups, it has been a neglected area of research in respiratory medicine and there remain no licensed disease-modifying therapies...

Acute exacerbations of chronic lung disease account for substantial morbidity and health costs. Repeated inflammatory episodes and attendant bronchoconstriction cause structural remodeling of the airway. Remodeling is a multicellular response to mucosal injury that results in epithelial cell state changes, enhanced extracellular deposition and expansion of pro-fibrotic myofibroblast populations. Areas covered: This manuscript overviews mechanistic studies identifying key sentinel cell populations in the airway and how pattern recognition signaling induces maladaptive mucosal changes and airway remodeling...

Cytokines are pivotal mediators of the immune response, and their coordinated expression protects host tissue from excessive damage and oxidant stress. Nevertheless, the development of lung pathology, including asthma, chronic obstructive pulmonary disease, and ozone-induced lung injury, is associated with oxidant stress; as evidence, there is a significant increase in levels of the modified guanine base 7,8-dihydro-8-oxoguanine (8-oxoG) in the genome. 8-OxoG is primarily recognized by 8-oxoguanine glycosylase 1 (OGG1), which catalyzes the first step in the DNA base excision repair pathway...

The risk of intracerebral hemorrhage still greatly limits the use of tPA in stroke patients. Research is ongoing in order to identify the pathophysiological mechanisms at play, detect predictive biomarkers and discover new pharmacological targets to develop preventive or curative treatments. Going through experimental and clinical studies, this review focuses on the role of neutrophils as key predictive biomarkers for thrombolysis-induced hemorrhages and as pharmacological targets to limit their occurrence...

Aspergillus colonization of the lower respiratory airways is common in normal people, and of little clinical significance. However, in some patients, colonization is associated with severe disease including poorly controlled asthma, allergic bronchopulmonary aspergillosis (ABPA) with sputum plugs, worse lung function in chronic obstructive pulmonary aspergillosis (COPD), invasive aspergillosis, and active infection in patients with chronic pulmonary aspergillosis (CPA). Therefore, understanding the pathophysiological mechanisms of fungal colonization in disease is essential to develop strategies to avert or minimise disease...

Background: Fruits and vegetables, due to high antioxidant capacity, may protect the lung from oxidative damage caused by tobacco smoke and potentially prevent chronic obstructive pulmonary disease (COPD). Only one study based on baseline diet has examined fruit and vegetable consumption in relation to risk of COPD, and no previous studies have examined long-term diet. Methods: We investigated whether long-term fruit and vegetable consumption was associated with COPD incidence among 34 739 women (age 48-83 years) in the population-based prospective Swedish Mammography Cohort...

Background: People with pulmonary tuberculosis (TB) are at risk of developing chronic respiratory disorders due to residual lung damage. So far, the scope of the problem in high burden TB countries is relatively unknown. Methods: Chronic respiratory symptoms (cough and phlegm lasting >2 weeks) and radiological lung abnormalities were compared between adults with and without a history of TB among the general population of Uganda. Multivariable regression models were used to estimate odds ratios with adjustment for age, gender, smoking, education, setting and region...

OBJECTIVES: Minimally invasive extracorporeal CO2 removal is an accepted supportive treatment in chronic obstructive pulmonary disease patients. Conversely, the potential of such technique in treating acute respiratory distress syndrome patients remains to be investigated. The aim of this study was: 1) to quantify membrane lung CO2 removal (VCO2ML) under different conditions and 2) to quantify the natural lung CO2 removal (VCO2NL) and to what extent mechanical ventilation can be reduced while maintaining total expired CO2 (VCO2tot = VCO2ML + VCO2NL) and arterial PCO2 constant...

Bronchiectasis is a chronic lung disease with permanently damaged airways predisposing to recurrent respiratory tract infections. There is an increasing prevalence of bronchiectasis in the elderly, affecting approximately 10 patients per 1,000 population. Studies have shown that older, frailer patients tend to have a more severe and symptomatic disease, with those aged 80 and above with worse quality of life, increased hospitalization and increased mortality. These patients will be encountered by clinicians working in all aspects of elderly care...
