Within less than 50 years, methicillin-resistant Staphylococcus aureus (MRSA) made a tremendous impact worldwide. It is not limited to medical facilities and healthcare institutions anymore. Indeed since two decades, cases of MRSA infections arising from the community among apparently healthy individuals are increasing. In this paper, I will present a case of community-associated MRSA sepsis followed by a comprehensive review about the history, pathogenesis, epidemiology, clinical presentations, diagnostic modalities, therapeutic options, contributing factors, growing cost and other pertinent elements of this newly evolving epidemic of MRSA infections.
Diabetic patients have greater risk for coronary heart disease (CHD) events after coronary artery bypass graft (CABG) surgery than nondiabetic patients. The Post CABG trial studied the effects of aggressive cholesterol lowering and low-dose anticoagulation in diabetic patients compared with nondiabetic patients. A double-blind, randomized clinical trial in 1,351 patients (1-11 years after CABG), the Post CABG trial consisted of two interventions (aggressive cholesterol-lowering versus moderate lowering and low-dose warfarin versus placebo) on angiographic end points. Angiographic changes in saphenous vein graft conduits 4.3 years after entry were compared in 116 diabetic and 1,235 nondiabetic patients. Seven clinical centers participated in the trial, as well as the National Institutes of Health project office (National Heart, Lung, and Blood Institute), the coordinating center (Maryland Medical Research Institute), and the Angiogram Reading Center (University of Minnesota). Baseline characteristics of the diabetic patients differed from the nondiabetic patients in the following ways: percentage of women participants, 15 vs. 7%, P = 0.002; mean baseline weight, 87.4 vs. 82.8 kg, P = 0.006; mean BMI, 29.5 vs. 27.6 kg/m2, P = 0.0002; mean systolic blood pressure, 141.7 vs. 133.6, P < 0.0001; mean triglyceride concentrations, 2.09 vs. 1.77 mmol/l, P < 0.0001; and mean HDL cholesterol concentrations, 0.93 vs. 1.02 mmol, P = 0.0001. The percentage of clinical events was higher in diabetic than nondiabetic patients (20.6 vs. 13.4, P = 0.033) and angiographic outcomes were not different. The benefits of aggressive cholesterol lowering were comparable in diabetic and nondiabetic patients for the angiographic end points. Warfarin use was not associated with clinical or angiographic benefit. Diabetic patients in the Post CABG trial had more CHD risk factors at study entry and higher clinical event rates during the study than nondiabetic patients. The benefits of aggressive cholesterol lowering in diabetic patients were comparable to those in nondiabetic patients for both angiographic and clinical end points. The small number of diabetic patients provided limited power to detect significant differences between diabetic and nondiabetic patients or between diabetic patients in the aggressive versus moderate cholesterol treatment strategies.
The spectrum of pulmonary pathology in the Middle East is as versatile as its civilizations and cultures. In this review, we outline the key challenges confronting pulmonologists in the Middle East. We shed light on the diverse conditions commonly encountered in the region, from the centuries-old illnesses of tuberculosis, to contemporary problems such as lung complications from chemical warfare. We specifically highlighted unique aspects related to respiratory illnesses in the Middle East, for example, climate factors in the desert region, cultural habits, for example, water-pipe smoking and disorders unique to the region, such as Behçet's disease. Pulmonologists are also faced with the consequences of modernization, including large immigrant population and associated social and health issues, rising incidence of obesity and sleep apnoea, and drug-resistant tuberculosis. Tackling these health issues will require an integrated approach involving public health, primary care as well as specialist pulmonology input, taking into consideration the unique cultural and environmental factors to ensure effective management and compliance to medical care.
Pneumothorax from bronchopleural or alveolo-pleural fistulae can be complicated by prolonged air leak (AL). This can occur in a variety of clinical settings. Examples include structural lung disease, such as bronchiectasis, and cavitary lung disorders. Prolonged AL is associated with prolonged hospital stay, atelectasis, pneumonia, and thromboembolic disease. Endobronchial valves (EBVs) have been recently introduced to manage such situations. The global experience in this novel therapeutic modality is still evolving. We report our preliminary experience with managing persistent AL treated successfully with EBVs and review the current literature on this subject. Our experience shows that EBVs are an effective tool for the management of prolonged AL from persistent bronchopleural or alveolo-pleural fistulae. It is a minimally invasive procedure recommended as an option, particularly in patients not fit for surgical repair.
Background:The association between bacterial infections and proton pump inhibitors (PPIs) has recently been studied with debatable results. Aim: The aim of this study was to investigate the relationship between PPIs and the development of spontaneous bacterial peritonitis (SBP) or other bacterial infections in cirrhotic patients. Materials and Methods: Consecutive cirrhotic patients hospitalized from 2007 through 2012 to Hamad General Hospital-, Doha, Qatar, were enrolled and classified as PPI users or non-users according to PPI consumption in the 90 days prior to hospitalization. Cirrhosis was clinically diagnosed by a combination of physical, biochemical, radiological, and endoscopic findings, or by liver biopsy. Results: A total of 333 patients were included in this study, of whom 171 (51.4%) used PPIs and 162 (48.6%) did not use PPIs. PPI users were significantly older in age (p = 0.001). There was no statistical difference between the 2 groups in sex distribution and etiology of cirrhosis (p > 0.05 for both parameters). PPI users had a significantly higher incidence of overall bacterial infection (38%) than non-PPI users (13.6%), p = 0.0001. Statistical significance is observed specifically for SBP and chest infection (p = 0.0006 and p = 0.01, respectively). In multivariate analysis, older age (> 60 years; OR = 1.246, 95% CI 1.021-08.486; p = 0.02), and PPI use (OR = 2.149, 95% CI 1.124-06.188; p = 0.01) were independent predicting factors for SBP and overall bacterial infection. Conclusion: The present study shows that PPI use, as well as older age (> 60 years), was an independent predicting factor for the development of overall infection and SBP in hospitalized cirrhotic patients. Unless it is indicated, PPI therapy should be avoided in this group of patients, particularly in those older than 60 years of age. Resumo Introdução: A associação entre infeções bacterianas e os Inibidores da bomba de protões (IBPs) tem vindo a ser estudada com resultados discutíveis. Objetivo: O objetivo deste estudo foi investigar a relação entre IBPs e o desenvolvimento de peritonite bacteriana espontânea (PBE) ou outras infeções bacterianas em doentes cirróticos. Material e Métodos: Doentes consecutivos com cirrose hospitalizados entre 2007 e 2012 no Hamad General HospitalQatar foram selecionados e classificados como utilizadores ou não utilizadores de IBPs de acordo com o seu consumo nos 90 dias prévios ao internamento. A cirrose foi clinicamente diagnosticada por uma combinação de achados no exame físico, no estudo bioquímico, radiológico e endoscópico; ou por biopsia hepática. Resultados: Um total de 333 doentes foi incluído neste estudo, 171 (51.4%) medicados com IBPs e 162 não (48.6%). Os utilizadores de IBPs eram significativamente mais velhos (p = 0.001). Não se observaram diferenças estatísticas entre os dois grupos no que se refere ao sexo ou etiologia da cirrose (p > 0.05 para os dois parâmetros). A incidência global de infeções bacterianas foi significativamente superior nos utilizadores de IBPs (38%) do ...
Invasive zygomycosis is a devastating fungal infection seen mostly in immune-compromised patients. We present a case of a 48-year old diabetic man, with aplastic anemia, who developed severe pulmonary mucormycosis that led to his rapid demise despite early diagnosis and treatment with liposomal amphotericin B. We also conducted an extensive review of the pathogenesis of invasive zygomycosis, its history, predisposing factors, clinical aspects, diagnostic modalities, treatment options, morbidity and mortality.
Objective and Background:Measures to promote patient satisfaction are important components of the assessment of outcome and strategies for the delivery of health care. In this article, we assess satisfaction among inpatients and the impact of demographics on satisfaction levels.Materials and Methods:This cross-sectional survey adapted from previously used survey tools and validated in our patient group included questions on demographics, communication skills, hospital environment, and the patients’ overall evaluation of the hospital. Inpatients from acute wards of five different specialties who stayed for at least 2 days were enrolled.Results:There were 988 respondents with a mean age of 39.1 years (25.9%) and the mean length of stay (LOS) of 10.0 days (24.1%). Illiteracy rate was 42.4%, and 43.1% were male. The overall satisfaction scores—out of five—were 4.3 (0.6%) for communication with nurses, 4.4 (0.4%) for communication with doctors, and 4.1 (0.3%) for hospital environment; 98.9% of the patients would recommend the hospital to their family and friends. The lowest score was for the “room environment” (3.99, 0.8%) and the highest for overall services of the hospital (4.7, 0.5%). Satisfaction levels drop significantly with LOS of more than 4 days (P < 0.006). The satisfaction was higher in females than males across all the three domains of care assessed (P < 0.005). The highest satisfaction seen in the obstetrics service could be explained by the nature of the condition normally seen in this department and the normally good outcome. There was higher satisfaction in the medical than surgical services but this reached a significant level for the overall center score domain only (4.1, 0.3% versus 4.0, 0.3%; P < 0.0001).Conclusion:The factors with positive impact on satisfaction were the female gender and shorter LOS. There was higher satisfaction in the medical than surgical services for all three domains reaching significant levels for center score only.
Alveolar haemorrhage is a rare and serious medical emergency with many causes. Diffuse alveolar haemorrhage due to warfarin therapy has been rarely reported in the literature. In this paper, we describe the case of 62-year-old woman with a history of chronic atrial fibrillation treated with warfarin, who was admitted to our institution with haemoptysis and dyspnoea. Alveolar haemorrhage was suspected clinically and subsequently confirmed by bronchoscopy. The patient required aggressive treatment with fresh frozen plasma, vitamin K and mechanical ventilation with a successful outcome. We emphasise the need for early diagnosis and fast therapeutic intervention, especially with over-anticoagulation (INR >9), in patients with this rare and potentially lethal condition.
