Acute eosinophilic pneumonia (AEP) is characterized by an acute onset respiratory illness with bilateral chest infiltrates and evidence of pulmonary eosinophilia. Cigarette smoking is the main risk factor, but drugs and other inhalational exposures have also been reported. Herein, the association between AEP and smoking devices other than cigarettes is reviewed The PubMed database was searched using terms such as ”smoking”, ”vaping”, ”e-cigarette”, ”waterpipe”, and ”marijuana”, along with other commonly used synonyms for these terms. In addition, eosinophilic lung diseases were also searched for using the same database. All cases of AEP were identified using the modified Philit criteria in association with the use of marijuana, waterpipe, e-cigarettes or heat-not-burn cigarettes. Cases associated with illicit drug use were excluded. Twelve cases were included with amedian age of 20 (15–60). 75% of patients studied were male. Exposures included marijuana smoking (n = 5), waterpipe usage (n = 2), heat-not-burn cigarette use (n = 2), e-cigarette use (n = 2) and synthetic cannabinoid use (n = 1). Arecent change in smoking habits was reported in 50% of patients. Presenting symptoms were dyspnea (91.6%), cough (66.6%), fever (66.6%) and chest pain (25%). 90% of patients had leukocytosis on presentation, but only 16.6% had peri-pheral eosinophilia. The median eosinophil percentage in bronchoalveolar lavage was 67.5% (0 to 78). Two patients had alung biopsy performed. Bilateral involvement on chest imaging was reported in all patients. Five patients (41.6%) required invasive mechanical ventilation and ten patients (83.3%) were treated in an intensive care unit. All patients responded to corticosteroid therapy with no relapses reported. Acute eosinophilic pneumonia is reported with smoking that does not include traditional cigarette smoking such as waterpipes, e-cigarettes, heat-not-burn cigarettes, and marijuana and can have asimilar presentation and clinical course.

Asthma incidence and severity are increased in obese populations. Systematic reviews have shown benefit from weight-loss interventions on asthma outcomes, but the role of bariatric surgery is still unclear. In this review, cohorts of obese asthmatic patients undergoing bariatric surgery were examined regarding different asthma outcomes. The available data on patients who were followed up showed improvements in asthma control, exacerbation risk, asthma-related hospitalisation, medication use and airway hyperresponsiveness, with some patients not requiring further treatment for asthma. Follow-up duration was variable, being mostly of 1 year, with some studies reporting long-term outcomes after 5 years. The studies reviewed had many limitations, including small numbers of patients, lack of control arm in some studies and lack of standardisation of asthma diagnosis, classification and outcome measures, in addition to possible reporting bias. Data on small numbers of patients also show the possibility of benefit exclusively in nonallergic asthma. Larger, more stringent clinical trials are needed before recommending bariatric surgery for treatment of asthma.

The aim of this study was to evaluate the effectiveness of total contact casting (TCC) in treating non-healing diabetic foot ulcers in Lebanese diabetic patients. Twenty-three diabetic patients were treated with TCC, and relevant data were collected retrospectively. Sixteen patients were analysed; the average duration of casting was 6 weeks, and 75% of the patients achieved complete ulcer closure without recurrence during one year of follow-up and without any complications. TCC appears to be an effective treatment of diabetic foot ulcers.
