Although there was more recognition for a patient's autonomy amongst physicians, most patients preferred a family centred model of care. Views towards information disclosure were midway between those of the USA and Japan. Distinctively, however, decisions regarding life prolonging therapy and assisted suicide were not influenced to a great extent by wishes of the patient or family, but more likely by religious beliefs.

Background and objectiveAlthough systemic lupus erythematosus (SLE) is the most common connective tissue disease affecting the lung, few studies have assessed risk factors that predict pulmonary manifestations. The objectives of the present study were to determine the prevalence of lung manifestations in SLE patients from Western Saudi Arabia by analysing results from high-resolution computed tomography (HRCT) scans and to identify independent risk factors for lung involvement.MethodsThis was a 10-year retrospective study involving 184 SLE patients. We examined all HRCT lung abnormalities and determined whether findings were associated with the presence of lupus nephritis (LN), SLE disease activity (as defined by SLE Disease Activity Index 2000 item scores ≥4 for any and all items) or levels of complement and anti-double-stranded DNA (anti-dsDNA).ResultsWe identified 61 patients (33%) with pulmonary involvement, and 52 (85%) of these subjects showed HRCT abnormalities. The most common HRCT findings were pleural effusion, consolidation and atelectasis (58%, 42% and 42%, respectively). There was a significant association between abnormal HRCT results and hypocomplementemia, high levels of anti-dsDNA and disease activity (P < 0.05), particularly with regard to pleuropericardial effusion and consolidation. Pulmonary abnormalities were significantly higher within the first five years after SLE diagnosis (P < 0.001). However, neither disease duration nor LN was associated with increased risk.ConclusionsLung manifestations were frequent in SLE patients from Saudi Arabia, with pleural effusion, consolidation and atelectasis being the most common. Low complement levels, high anti-dsDNA levels and disease activity were significantly associated with abnormal HRCT findings (all P < 0.001).

Poor compliance with conventional asthma medications remains a major problem in achieving asthma control. Nigella sativa oil (NSO) is used traditionally for many inflammatory conditions such as asthma. We aimed to investigate the benefits of NSO supplementation on clinical and inflammatory parameters of asthma. NSO capsules 500mg twice daily for 4 weeks was used as a supplementary treatment in a randomised, double-blind, placebo-controlled trial (RDBPCT) in asthmatics (clinicaltrials.gov: NCT02407262). The primary outcome was Asthma Control Test (ACT) score. The secondary outcomes were pulmonary function test, blood eosinophils, and total serum Future studies should follow asthmatics for longer periods in a multicentre trial.

OBJECTIVES AND BACKGROUND:Lung cancer accounts for 4% of all newly diagnosed cancers in Saudi Arabia. The pattern of presentation is unknown. The objectives of this study were to assess the clinical, radiological, pathological, biochemical and bronchoscopic abnormalities in lung cancer patients and to compare our findings with those reported in the literature.METHODS:A total of 114 patients with proven lung cancer were selected for the study. A questionnaire concerning patients' demographic data was obtained; the abnormalities and the cell types of lung cancer were recorded prospectively in each subject.RESULTS:A total of 114 patients with lung cancer were studied. Mean age ± SD was (59.8 ± 10.8) years, and (71.1%) were smokers and 95.1% of them were male, (90.1%) smoked >20 pack/yr (96.2%) for 20 years or more. Cough (76.3%) and clubbing (40.4%) were the most common symptom and physical abnormality respectively. The right lung (64.9%) was more commonly affected than the left (37.7%). Metastases were present in (49.1%) at presentation. The right and left upper bronchi (24% vs. 16%) were the mostly affected. Hypercalcemia was more common in squamous cell, while hyponatremia was more common in adenocarcinoma, and small cell. Squamous cell carcinoma was the most common cell type (51.8%) and significantly associated with smoking (P ≤ 0.001)CONCLUSION:Squamous cell carcinoma was the most common cell type, and significantly associated with smoking. The incidence of metastasis was high at presentation. The right lung and right upper bronchus were often affected. Hypercalcemia and hyponatremia were the most common biochemical abnormalities.
