Survey instruments used in clinical and epidemiological research on waterpipe tobacco smoking: a systematic review

<p>Abstract</p> <p>Background</p> <p>The primary objective was to systematically review the medical literature for instruments validated for use in epidemiological and clinical research on waterpipe smoking.</p> <p>Methods</p> <p>We searched the following databases: MEDLINE, EMBASE, and ISI the Web of Science.

We included papers reporting on the development and/or validation of survey instruments to measure waterpipe tobacco consumption or related concepts. Two reviewers used a standardized and pilot tested data abstraction form to collect data from each eligible study using a duplicate and independent screening process.

One instrument was designed to measure knowledge, attitudes, and waterpipe use among pregnant women and was shown to have internal consistency and content validity. Three instruments were designed to measure waterpipe tobacco consumption, two of which were reported to have face validity. The fifth instrument was designed to measure waterpipe dependence and was rigorously developed and validated. One of the studies of prevalence and none of the studies of health effects of waterpipe smoking used validated instruments.</p> <p>Conclusions</p> <p>A number of instruments for measuring the use of and dependence on waterpipe smoking exist.

The prevalence of waterpipe tobacco smoking among the general and specific populations: a systematic review

Abstract Background The objective of this study was to systematically review the medical literature for the prevalence of waterpipe tobacco use among the general and specific populations. Methods We electronically searched MEDLINE, EMBASE, and the ISI the Web of Science. We selected studies using a two-stage duplicate and independent screening process. We included cohort studies and cross sectional studies assessing the prevalence of use of waterpipe in either the general population or a specific population of interest. Two reviewers used a standardized and pilot tested form to collect data from each eligible study using a duplicate and independent screening process. We stratified the data analysis by country and by age group. The study was not restricted to a specific context. Results Of a total of 38 studies, only 4 were national surveys; the rest assessed specific populations. The highest prevalence of current waterpipe smoking was among school students across countries: the United States, especially among Arab Americans (12%-15%) the Arabic Gulf region (9%-16%), Estonia (21%), and Lebanon (25%). Similarly, the prevalence of current waterpipe smoking among university students was high in the Arabic Gulf region (6%), the United Kingdom (8%), the United States (10%), Syria (15%), Lebanon (28%), and Pakistan (33%). The prevalence of current waterpipe smoking among adults was the following: Pakistan (6%), Arabic Gulf region (4%-12%), Australia (11% in Arab speaking adults), Syria (9%-12%), and Lebanon (15%). Group waterpipe smoking was high in Lebanon (5%), and Egypt (11%-15%). In Lebanon, 5%-6% pregnant women reported smoking waterpipe during pregnancy. The studies were all cross-sectional and varied by how they reported waterpipe smoking. Conclusion While very few national surveys have been conducted, the prevalence of waterpipe smoking appears to be alarmingly high among school students and university students in Middle Eastern countries and among groups of Middle Eastern descent in Western countries

Methodological rigor and reporting of clinical practice guidelines in patients with allergic rhinitis : QuGAR study

Background: There are several clinical practice guidelines about the management of allergic rhinitis (AR) being used by clinicians. Objective: We sought to assess the methodological rigor and transparency of reporting of clinical practice guidelines for the management of AR. Methods: We systematically searched MEDLINE, the TRIP database, and professional societyWeb sites for all guidelines about the management of AR published in English after the year 2000. Four reviewers independently assessed the rigor of development and reporting of included guidelines using the Appraisal of Guidelines for Research and Evaluation II instrument. Results: Our search revealed 432 records, of which 34 full-text articles were assessed for eligibility and 10 fulfilled inclusion criteria. Overall methodological rigor and reporting of guidelines varied from fulfilling most of the Appraisal of Guidelines for Research and Evaluation II criteria to almost none. Across all guidelines, the best reported domain was clarity of presentation, and the least rigorously addressed domain was applicability of guidelines. Agreement beyond chance among the 4 appraisers was fair. Conclusions: Guideline users should be aware of the difference in the rigor of development and quality of reporting of guidelines about the management of AR. They should choose higher-quality guidelines to use in their practice and teaching. For most reviewed guidelines, there is room for improvement, particularly in the domains of applicability and implementation

Successful use of cyclosporine as treatment for eosinophilic cystitis: a case report

Background Eosinophilic cystitis is a rare inflammatory disorder characterized by eosinophilic infiltration of all layers of the urinary bladder wall. Due to lack of consensus and potential for side effect from various therapeutic options, treatment of the disease is often challenging.Case presentation A 64-year old woman with hypertensive nephropathy resulting in stage III chronic kidney disease, obstructive sleep apnea, and obstructive lung disease presented with a 4 month history of dysuria, urgency, frequency, and persistent hematuria. Based on eosinophilic infiltration on bladder wall biopsy in the absence of any evidence of infection, malignancy, or immune disorder, she was diagnosed with eosinophilic cystitis. Despite multiple medication regimens, her symptoms persisted, requiring high-dose prednisone with steroid-related side effects. After four months, she was started on cyclosporine, which led to symptomatic improvement and reduction in prednisone dosage. At that time, repeat urine cytology and cystoscopy did not reveal friable tissues or eosinophiluria.Conclusion This case illustrates the utility of using cyclosporine to treat eosinophilic cystitis in adult patient with multiple comorbid conditions. Keywords: Eosinophilic cystitis, Cyclosporine, Steroid

Latest approaches to the diagnosis and management of food allergies in children

Adverse food reactions are a challenge for physicians. As the prevalence of this condition rises, it is important that paediatricians and other health care professionals adeptly diagnose this condition. We begin by discussing the relevant points in history and physical examination, then we discuss the recent effective diagnostic tests and techniques available for doctors and patients, along with several management options. Over the last decade, there have been major advancements in this field and novel mechanisms have been proposed which efficiently modulate immune mechanisms involved. Although results are only preliminary, they do however, indicate a promising future for patients with food allergies
