Our results demonstrated that the CAT is a simple and valid tool for assessment of HRQOL in chemical warfare patients with COPD and can be used in clinical practice.
ObjectivesChronic obstructive pulmonary disease (COPD) is one of the main late complications of sulfur mustard poisoning. The aim of this study was to evaluate serum levels of interleukin (IL)-6 in war veterans with pulmonary complications of sulfur mustard poisoning and their correlation with severity of airways disease.MethodsFifty consecutive patients with sulfur mustard poisoning and stable COPD, and of mean age 46.3 ± 9.18 years were enrolled in this study. Thirty healthy men were selected as controls and matched to cases by age and body mass index. Spirometry, arterial blood gas, six- minute walk test, BODE (body mass index, obstruction, dyspnea, and exercise capacity), and St George’s Respiratory Questionnaire about quality of life were evaluated. Serum IL-6 was measured in both patient and control groups.ResultsFifty-four percent of patients had moderate COPD. Mean serum IL-6 levels were 15.01 ± standard deviation (SD) 0.61 pg/dL and 4.59 ± 3.40 pg/dL in the case and control groups, respectively (P = 0.03). There was a significant correlation between IL-6 levels and Global Initiative for Chronic Obstructive Lung Disease stage (r = 0.25, P = 0.04) and between IL-6 and BODE index (r = 0.38, P = 0.01). There was also a significant negative correlation between serum IL-6 and forced expiratory volume in one second (FEV1, r = −0.36, P = 0.016).ConclusionOur findings suggest that serum IL-6 is increased in patients with sulfur mustard poisoning and COPD, and may have a direct association with airflow limitation.
Background:The objective structured clinical examination (OSCE) has been introduced as an efficient method for the assessment of medical students.Objectives:The aim of the present study was to determine the satisfaction level of undergraduate medical students of internal medicine department with the OSCE.Materials and Methods:This was a descriptive cross-sectional study, performed on all available undergraduate students at the end of their internal medicine training period in Mashhad University of Medical Sciences. The students responded to 15 multiple-choice questions with confirmed validity and reliability.Results:The majority of the students (94.5%) had a positive attitude toward the OSCE and mentioned that the OSCE format was a more appropriate type of exam than other methods of testing; however, 79.1% thought that the OSCE format was stressful. In addition, the participants’ sex had no effect on their level of satisfaction with the examination. Likewise, there was no significant correlation between their level of satisfaction and their age, marital status, or lack of previous experience with this type of exam.Conclusions:If the exam standards are met and a uniform dispersion of the scientific content is maintained, the OSCE method of assessment can be recommended as an efficient and applicable method for assessing medical students.
Background Malignant pleural effusion continues to be a common problem in patients with metastatic disease. This study was conducted to compare the efficacy and safety of bleomycin pleurodesis with povidone-iodine pleurodesis through a chest drain as palliative treatment for recurrent malignant pleural effusion. Methods Sixty cancer patients (36 males and 24 females) with recurrent malignant pleural effusion were enrolled in a prospective randomized trial. Thirty patients received povidone-iodine pleurodesis and 30 received bleomycin pleurodesis. Age, sex, side of the primary pathology, treatment outcome (recurrence and relapse time), and complications were analyzed. Results The mean age was 59.63 ± 7.68 years in the povidone-iodine group and 57.97 ± 9.27 years in the bleomycin group ( p = 0.452). The complications were identical in both groups: 2 (6.7%) patients had chest pain, 2 (6.7%) had fever, and one (3.3%) had hypotension. There was a good response to therapy in 20 (66.7%) patients in the bleomycin group and 25 (83.3%) in the povidone-iodine group ( p = 0.136). Conclusion The results of this study indicate that povidone-iodine should be considered as a selective chemical agent to perform pleurodesis in patients with recurrent malignant pleural effusion because it has the same effect but costs less than bleomycin.
Chronic obstructive pulmonary disease (COPD) is a leading cause of morbidity and mortality worldwide. It is now considered a systemic inflammatory syndrome and is associated with important comorbidities. In addition to spirometry for evaluating the severity of airflow obstruction, an instrument is required for comprehensive assessment of the disease. The COPD Assessment Test (CAT) is a simple and valid tool for evaluating patient symptoms. The CAT can improve patient–physician communication during routine clinical visits and is useful for assessing functional status and response to treatment. The CAT has a strong correlation with other health status questionnaires, such as the St George’s Respiratory Questionnaire. The main advantages of the CAT are its thorough coverage of the important clinical aspects of disease burden and the shorter time involved in completing it. The aim of this paper is to review the role of the CAT, to compare it with other health-related quality of life questionnaires in the assessment and management of COPD patients, and to emphasize the importance of patient–physician communication in the management of patients with the disease.
Background:Idiopathic pulmonary hypertension (IPAH) is a rare, debilitating, and fatal disease. Late-onset treatment can lead to right heart failure, multiple organ damage, and death. Since the thyroid plays a major role in the metabolism and hemodynamics in humans, the screening of thyroid function is crucial. Thyroid dysfunction has been reported to cause pulmonary hypertension, but the thyroid is also involved in IPAH.Objectives:The aim of this study was to evaluate thyroid function in IPAH patients.Patients and Methods:Fifty-three IPAH patients aged 16 - 75 years-old were enrolled in this cross sectional study, and their right ventricular functions, hemodynamics, and six minute walk tests (SMWTs) were evaluated. Thyroid function tests were conducted, and their associations with the patients’ pulmonary arterial pressures (PAPs) and functional capacities were assessed. The data were analyzed using the SPSS 15 statistical software.Results:In this research, 84.8% of the participants were women. The mean PAP was 51.6 mmHg (31-87) and mean thyroid stimulating hormone (TSH) level was 4.2 mIU/ml (0.7 - 10). Subclinical hypothyroidism was detected in 26 patients (49.1%). There were significant correlations of the TSH level with the right ventricular (RV) end diastolic dimension (P value = 0.05) and triiodothyronine (T3) with the tricuspid annular plane systolic excursion (TAPSE) (P value = 0.04), an inverse relationship between the SMWT and the TSH level (P value = 0.004), but no significant relationship between these parameters and the thyroxine (T4) level.Conclusions:IPAH is associated with subclinical hypothyroidism and low patient functional capacity, and is more common in RV failure.
