Suspension laryngoscopy is one of the most common otolaryngological procedures for the diagnosis and surgical approach to the larynx. However, most thoracic surgeons are not familiar with the procedure and seldom use it. The indications for its use are similar to those for that of rigid bronchoscopy (dilatation, endoprosthesis insertion, and tumor resection). It can be performed in children and adults. Suspension laryngoscopy is an alternative when rigid bronchoscopy is unavailable and is therefore a viable option for use at smaller facilities. In this communication, we describe the technique and the applications of suspension laryngoscopy in thoracic surgery.

In poor and underdeveloped countries, including Brazil, pulmonologists have great difficulty in maintaining a level of service that keeps pace with advances in current knowledge, in keeping up to date with newly developed techniques, and in pursuing research. Due to the rising costs of scientific journal subscriptions, one of the main problems is lack of access to the scientific literature. The term "digital divide" refers to the gap between those who can and those who cannot effectively use new information technology and tools such as the Internet to communicate within and between countries. In this report, we call attention to some solutions to this situation. In particular, the SciELO Project, the CAPES Periodicals portal and the HINARI project, as well as several others, provide access at little or no cost. These options are explained in detail herein.

Asthma is characterized by variable airflow obstruction, hyperresponsiveness of airways to endogenous or exogenous stimuli and inflammation. Inadequacy of the techniques to use different inhalation devices is a cause of no response to treatment. The main purpose of this study was to evaluate how 20 medical students, 36 resident physicians on Internal Medicine/Pediatrics, and 40 asthma patients used three devices for inhalation therapy containing placebo. All patients were followed at the Pulmonary Outpatient Service of Botucatu Medical School and had been using inhaled medication during the last six months. The following devices were evaluated: metered dose inhalers (MDI), dry powder inhalers (DPI), and MDI attached to a spacer device. A single observer applied a protocol containing the main steps necessary to obtain a good inhaler technique to follow and grade the use of different devices. Health care professionals tested all three devices and patients tested only the device being used on their management. MDI was the device best known by doctors and patients. MDI use was associated with errors related to the coordination between inspiration and device activation. Failure do exhale completely before inhalation of the powder was the more frequent error observed with DPI use. In summary, patients have not been receiving repeated instruction on how to use inhaled medication and health care professionals are not well prepared to adequately teach their patients.

In March of 2009, a flu epidemic began in Mexico. Shortly thereafter, similar cases appeared in other countries, alerting authorities to the risk of a pandemic. This article details the principal signs and symptoms of infection with the swine-origin Influenza A (H1N1) virus. In addition, the measures to be taken in suspected or confirmed cases are addressed, as are the procedures to follow in relation to contacts. Furthermore, the drugs used in the prophylaxis against and the treatment of infection with the H1N1 virus are described.

Electronic nicotine delivery systems, electronic cigarettes, or vapes have been extensively marketed as a safer alternative to combustible cigarettes and as aids for smoking cessation. However, electronic cigarettes often deliver more potent forms of nicotine, such as nicotine salts and synthetic nicotine, which are masked by appealing aromas and flavors, thereby attracting nonsmoking children and adolescents. On the other hand, adults dependent on freebase nicotine (found in conventional cigarettes) often become addicted to these new forms of nicotine in electronic cigarettes. Dual use is common and poses significant health risks, potentially exceeding those of using either product alone. Dual users experience increased odds of COPD, lung cancer, cardiovascular disease, and stroke. Electronic cigarettes represent a new challenge for global public health and health professionals. There are currently no specific guidelines for vaping cessation treatment. This study sought to provide health professionals with a comprehensive vaping cessation approach, including effective strategies such as behavioral support, nicotine replacement therapy, and the use of nicotine-free medications.

We report the case of a 53-year-old male patient with a rare profile: bronchial casts associated with the use of pegylated interferon and ribavirin. The patient sought treatment in a pulmonology clinic with a history of progressive dyspnea for four months that had evolved to progressive cough followed by frequent and abundant elimination of bronchial casts. The patient was initially treated with bronchodilators, as well as with oral and inhaled corticosteroids. Fiberoptic bronchoscopy, bronchoalveolar lavage and sputum analysis were carried out but did not contribute to the elucidation of the diagnosis. The symptoms developed while the patient was receiving pegylated interferon and ribavirin for the treatment of hepatitis C. The symptoms resolved 30 days after the discontinuation of the treatment. To our knowledge, this is the first report of bronchial casts caused by the use of pegylated interferon and ribavirin.
