Correlation of worldwide incidence of type 1 diabetes (DiaMond) with prevalence of asthma and atopic eczema (ISAAC)

Introduction:  Environmental factors play a role in pathogenesis of both type 1 diabetes and atopic disease but they remain incompletely understood. T cell‐mediated responses primarily of the T helper type 1 (Th1) are involved in type 1 diabetes while T helper type 2 (Th2) responses favour allergic disease. This TH 1/TH 2 paradigm is currently the source of much controversy in various studies.

Carbamazepine-induced drug reaction with eosinophilia and systemic symptoms syndrome in a 35-year-old man with epilepsy.

Abstract The Drug Reaction with Eosinophilia and Systemic Symptoms syndrome describes a hypersensitivity reaction to a number of drugs. It is characterized by a triad of fever, rash, and internal organ involvement. Carbamazepine is suspected to be the cause of the Drug Reaction with Eosinophilia and Systemic Symptoms syndrome in this young man who presented with fulminant hepatitis and an exfoliating rash 8 weeks after starting carbamazepine. Symptoms gradually resolved after stopping carbamazepine and starting systemic steroids. Because we encountered only a few similar cases in the literature, we wish to highlight the importance of recognizing these symptoms as a syndrome that can be fatal, especially if not recognized early.

Pulmonary rehabilitation in chronic obstructive pulmonary disease: Outcomes in a 12 week programme

Abstract Objective. The optimal time-frame for pulmonary rehabilitation (PR) in patients diagnosed with chronic obstructive pulmonary disease (COPD) is still debated. A 12 week programme was designed looking at whether the benefits were reached at or before a 12 week period of PR for COPD patients. Method. Seventy-five patients (59 males, 16 females) aged 40 75 years were referred from the local general hospital in Malta. Baseline assessments were carried out on all patients 2 weeks before initiation of the programme. Sixty patients were eligible to start a twice-weekly, 12 week multidisciplinary programme delivered after the screening process. The Six-Minute Walk Test (6MWT), dyspnoea score using the Borg scale, spirometry testing, plethysmography, COPD Assessment Tool (CAT) score, St Georges Respiratory Questionnaire (SGRQ) and Hospital and Anxiety scale score were monitored at 4 weekly intervals throughout the 12 weeks of PR for these COPD patients. Results. The 6MWT distance increased by a mean total of 132.45 m (p < 0.001) by 12 weeks, with the highest change recorded in the first 4 weeks for the milder COPD patients. Lung function test improvements were marginal. Borg scale readings at rest and following exertion decreased significantly from weeks 0 to 4 but remained fairly constant thereafter. The Body mass index, airway Obstruction, Dyspnoea, and Exercise capacity (BODE) index, SGRQ and CAT score values decreased significantly throughout the weeks irrespective of the initial Medical Research Council score. Anxiety scoring decreased significantly by 12 weeks, while the depression rating improved by 8 weeks. Conclusion. These findings show that 12 weeks of PR in this cohort of COPD patients resulted in clinically significant changes in functional outcome measures which are supported by statistically significant changes in health-related quality of life measures. In milder COPD cases, by 4 weeks of PR gains in exercise tolerance had already resulted. The more severe group required more time to obtain improvements. Therefore, hospitals could organize shorter PR programmes for larger numbers of patients with milder COPD.

Influenza A: another cause of SIADH?

The syndrome of inappropriate antidiuretic hormone (SIADH) secretion is a frequent cause of hyponatraemia. It is a dilutional hyponatraemia secondary to impaired urinary dilution in the absence of renal disease or any identifiable non-osmotic stimulus known to induce antidiuretic hormone secretion. SIADH can arise secondary to various respiratory tract infections; however, the association between SIADH and influenza A infection is described in only a few cases in the literature. The authors present a case report of influenza A that may have caused a profound SIADH-related hyponatraemia.

The Impact of School Environment on Children's Respiratory Health

Background/Aims: School indoor air quality is important because children spend most of their time outside home within the school environment. This study aimed to investigate the school environment and its impact on the respiratory health of the children. Methods: A total of 191 pupils in the 9- to 11-year age group were selected from 5 primary state schools. Validated school and health questionnaires, spirometry, acoustic rhinometry, nasal lavage, urine for environmental tobacco smoke biomarkers and traffic counts were used. Results: Cumulative (32.98%) and current wheezing (17.8%) were in keeping with the International Study of Asthma and Allergies in Childhood Malta data. Southern schools had the highest prevalence of current wheezers (OR 3.77; p = 0.012), rhinoconjunctivitis (OR 3.59; p = 0.003) and nasal eosinophilic cationic protein levels (p < 0.001). Small openable window areas increased rhinitic symptoms (OR 3.14; p = 0.016). Classes facing roads had increased current wheezers (OR 2.27; p = 0.03) and exhaled carbon monoxide (eCO) levels (p < 0.001). Current wheezing was significantly associated with the number of light and heavy vehicles passing near the school (p < 0.001). The presence of smokers at home was significantly associated with urinary cotinine and 3HC (p < 0.001). Proximity to power plants increased the current wheezers (OR 5.89; p = 0.001) who had impaired spirometry (p = 0.003). Asthma symptoms (OR 5.25; p = 0.001) and elevated eCO levels (p < 0.001) were associated with fuel storage facilities near schools. The accumulation of dust on flat surfaces within classrooms was related to wheezing (OR 5.23; p = 0.001). Conclusions: The school environment had a direct impact on the respiratory health of children, with several factors having a direct impact on the childrens health.
