formaldehyde is a common indoor pollutant with irritant properties. the present case control study was undertaken among 37 exposed staff with formaldehyde and 19 non exposed (referent) ones to study the acute and chronic effects of it in two educational hospitals. all subjects were tested for respiratory function by a portable alpha vitalograph-uk. in addition using a respiratory questionnaire,...

RESULTS. There were no differences in any of the allergic disease outcomes between the probiotic and placebo groups. Both groups had a similar prevalence of allergic disease generally and asthma, allergic rhinoconjunctivitis, and eczema specifically. The prevalence of allergic sensitization, according to results of both skin prick testing and IgE testing, was also similar between the 2 groups, ...

background : the present study was undertaken to ascertain whether (or not) long term occupational exposure to low (sub-tlv levels) atmospheric concentrations of chlorine gas was associated with any significant decrements in the parameters of pulmonary function and/or  increased prevalence of respiratory symptoms. methods : in this retrospective cohort study that was performed in 2012, 54 worke...

Background: Buds of granulation tissue within the lumen of distal pulmonary airspaces characterises organising pneumonia (OP). This study aimed to analyse the clinical and pathological features and prognosis of patients with cryptogenic OP. Methods: Twenty-seven patients were retrospectively analysed. A multidisciplinary team (a clinician, radiologist, and pathologist) diagnosed all patients. C...

Liver cirrhosis is a common long‑term outcome of chronic hepatic inflammation. Patients with liver may also have pulmonary complications. There are several reasons for dysfunction in cirrhosis, including intrinsic cardiopulmonary unrelated to disease and specific disorders related the presence and/or portal hypertension.

Airway mucus hypersecretion Health effects caused by air pollutants may range from subtle biochemical or physiological signs, such as mildly reduced lung function, to difficult breathing, wheezing, coughing and exacerbation of existing respiratory conditions such as asthma. The aim of this study was measuring the adverse health effects of air pollution on lung function of primary school student...

Photodynamic therapy (PDT) that is based on the science of photochemistry has been recognized as a lung sparing local therapeutic modality that can achieve remarkable responses. It is an alternative treatment for early stage lung cancer patients who have poor lung function or multiple sites of cancer. Recently we treated a 70-year-old man who presented with squamous carcinoma in situ at a previ...
