Page 222BackgroundObstructive Lung Diseases (OLDs), could lead to progressive hyperinflation of the lungs that cause increased work of breathing, impaired gas exchanges and functional limitations in patients. In this study, thoracic circumference of patients in upper and lower third were measured directly and the association of the upper to lower third width of chest with spirometric parameters was evaluated.Materials And MethodsIn this cross-sectional study, five hundred twenty nine consecutive patients, with obstructive pattern in spirometry (FEV1/FEVCResultsWe found that in patients with UTCC/LTCC ratio > 0.8, UTCC had significant correlation with FEV1 and FEV1/FVC (R: 0.069, 0.055); Moreover significant correlation was found in UTCC, LTCC and UTCC/LTCC ratio with ACT score in this subgroup (R: -0.123, -0.092, -0.124)On the other hand in patients with UTCC/LTCC ratio > 0.9 , UTCC and LTCC had significant correlation with FEV1 (R: 0.07, 0.051).ConclusionUTCC/LTCC ratio > 0.8, may be a predictor of obstructive pattern in patients. This is more important in some occations, for example during preoprative evaluation of a patient in an emergency conditions which there is no enough time for performing appropriate diagnostic tests such as spirometry to reveal the type and severity of obstructive pulmonary diseases.Keywords: Spirometry, Lung Diseases, Obstructive

Page 227BackgroundOne of the most common indications for pleuroscopy is undiagnosed pleural effusion, which comprises about 25% of all cases of pleural effusions, which remain undiagnosed despite primary tests. Pleuroscopy was performed for the first time in Iran in Masih Daneshvari hospital located in Tehran. The aim of this study was to assess the diagnostic yield of pleuroscopy performed in this center in Iran.Materials And MethodsThree-hundred patients with undiagnosed pleural effusions were enrolled in this study. For all patients, primary tests including pleural effusion analysis, cytology and closed pleural biopsy (if needed) were conducted and all of them were inconclusive. The semirigid thoracoscopy (pleuroscopy) was performed for all patients for diagnostic purposes.ResultsEighty-seven percent of the peluroscopies were diagnostic and 67% of them were diagnosed as malignancy while the rest were diagnosed as tuberculosis. Only 11 patients developed minor complications.ConclusionIn conclusion, pleuroscopy is a safe procedure when performed by a skilled and experienced practitioner; it has a high diagnostic yield and results in only minor complications.Keywords: Pleuroscopy, Pleural effusion, Diagnosis, Thoracoscopy

Page 232IntroductionAcquisition of chronic diseases such as asthma leads to psychological, mental and physical complications in adolescents, and hence their self-esteem may be compromised. Therefore, the present study was conducted to assess the effect of Orems self-care model on self-esteem of adolescents with asthma.Materials And MethodsThis semi-experimental study enrolled 64 asthmatic adolescents referred to Shariati Hospital, Isfahan. Subjects were assigned to two groups of control and intervention consecutively. Then, the self-care training program was conducted according to Orems self-care model in eight two-hour sessions based on self-care needs, and self-esteem was measured in the two groups prior to and two months after the last training session. The data were collected by a questionnaire of demographic characteristics and the Coopersmith Self-Esteem Inventories (CSEI) and analyzed by SPSS version 20.ResultsIndependent t-test showed a significant difference in the mean score of self-esteem between the intervention and control groups after the training (P0.05).ConclusionRegarding the effect of Orems self-care model on self-esteem of adolescents with asthma, we recommend the use of this model as a care intervention in healthcare centers to promote adolescents health.Keywords: Models, Nursing, Self Concept, Adolescent

Page 238BackgroundSmoking and physical inactivity are two major risk factors for non-communicable diseases (NCDs). Not only these factors have a causal effect on NCDs, but they can also affect each other. This study aimed to assess the relationship between these factors as well as their effect on NCDs.Materials And MethodsA total of 2,602 healthy adults aged 30-60 years participated in this survey in 2010. Data on demographic characteristics, medical history, smoking status, physical activity and anthropometric measures including weight and height were collected and analyzed. The effect of smoking on physical activity was evaluated by logistic regression adjusting for potential confounders.ResultsAmong demographic characteristics, only age (PConclusionThe present study showed that cigarette smoking negatively affects the quality of physical activity.Keywords: Harm reduction, Health services, Smoking, Global health, Physical activity

Page 246BackgroundInterventional bronchoscopic procedures are novel diagnostic and therapeutic methods in pulmonology, which may be unpleasant and dangerous to the patients; therefore, sedation and in some cases general anaesthesia are recommended. But adjusting the level of sedation is a challenge. In this study we intended to define a range of bispectral index (BIS) score suitable for these procedures.Materials And MethodsAll patients referred to our interventional bronchoscopy unit were enrolled in the study. Sedation was induced using midazolam, sufentanil, and propofol with the patient breathing spontaneously. The target level of sedation was to reach a Ramsay sedation score of 3 and patient tolerance in performing the procedure. The BIS score was recorded at baseline and every five minutes thereafter. Correlation between different BIS values, propofol dosage, duration of procedure, and awakening time was evaluated.ResultsA total of 70 patients were enrolled in this study with a mean age of 50± 16 years and 34 (48.6%) of them were males. The mean baseline BIS was 96±3.7, and the mean time to reach stable BIS (stable time) was 7.9±6 minutes. The mean stable BIS was 52±13.5 and 70% of patients had stable BIS between 40 and 60.ConclusionBIS is a useful objective tool for evaluation of sedation, which can guide us through bronchoscopy and related procedures. According to our observational study, reaching the mean BIS level of 52±13.5 is required to prevent complications and ensure feasibility of the procedure.Keywords: Bispectral index, Bronchoscopy, Intervention, Anaesthesia

Tracheal Stenosis and Cuff Pressure: Comparison of Minimal Occlusive Volume and Palpation TechniquesPage 252BackgroundTracheal stenosis, which has received more emphasis recently, is a common post intubation complication and may develop due to different reasons. One important reason is the endotracheal tube cuff pressure. Therefore, this study sought to examine the accuracy of diagnostic test for palpation and minimal occlusive volume techniques to measure the endotracheal tube cuff pressure.Materials And MethodsIn this cross sectional study, the accuracy of diagnostic tests for palpation and minimal occlusive volume techniques to measure the endotracheal tube cuff pressure was assessed in 101 patients aged over 18 years who had undergone open heart surgery and post-surgical mechanical ventilation in the ICU.ResultsIn the palpation technique, the cuff pressure of 27 patients (26.7%) was reported to be out of the permissible range and for the rest of them (74 patients, 73.3%) it was within the permissible range. Then, the cuff pressure was checked by the standard method using a manometer and after comparing the results it was found that the cuff pressure of 92 patients (91.1%) was not in the permissible range and only nine patients (8.9%) had a cuff pressure within the permissible range (20-30 cm H2O). In minimal occlusive volume method compared with the standard method, 22 patients (21.7%) had cuff pressure within the permissible range of 20-30 cm H2O, and 79 of them (78.2%) had cuff pressure out of the permissible range and higher than the upper limit.ConclusionThis study recommends that the best way to measure the endotracheal tube cuff pressure is to use a cuff manometer, and when it is not available, the minimal occlusive volume would be a better alternative compared to the palpation technique to keep the cuff pressure within a proper range to avoid tracheotomy complications such as tracheal stenosis.Keywords: Trachea, Tracheal stenosis, Cuff pressure

Page 257BackgroundFungi existing in hospital departments may grow and produce micro-colonies. The spores arising from these micro-colonies circulate easily and could be inhaled by patients and cause infections in immune-compromised subjects. Due to the lack of an acceptable method of sampling and evaluation of microbiological quality of air in the isolation units, the purpose of this study was to determine the concentrations of airborne fungi through active and passive sampling and also identify fungi genera in the air of the isolation unit.Materials And MethodsThe air of the isolation unit was monitored through active and passive sampling. In passive sampling, the plates were placed in the room. The active sampling was performed in the hematology unit by using a slit-to-agar biological air sampler with a flow rate of 10 L/minute. Plates were incubated at 30°C for 10 days and were examined daily for fungal growth. Fungal species were identified on the basis of their macroscopic and microscopic morphological features.ResultsIn active samples, Penicillium spp. was the predominant genus (66.8%), followed by Aspergillus spp. (23.9%) and Cladosporium spp. (2.5%). Yeast spp. accounted for only 2.2% of the isolated fungi. In passive samples, Penicillium spp. (94.4%) was the most frequently found fungi, followed by Aspergillus spp (2.2%), Cladosporium spp. (1.1%) and Yeast spp. (0.5%). The identified genera included Penicillium, Aspergillus, Alternaria, Mucorales, Cladosporium, Yeasts and other filamentous fungi.ConclusionActive and passive sampling can be used for monitoring the fungal content of air. Assessment of fungal contamination profiles in hospitals may provide important information about the level of fungal concentration in the hospitals and for the control of nosocomial infections. In addition, installation of special ventilation systems equipped with HEPA filters in hematology wards could enhance the quality of air. Also, observing sanitary protocols for disinfection of the surfaces is imperative for infection control.Keywords: Fungal contamination, Active, passive sampling, Hematology unit
