Myocardial perfusion imaging using a technetium-99m Sestamibi in asymptomatic and low risk for coronary artery disease patients with diagnosed systemic lupus erythematosus

Introduction: The aim of the present study was to evaluate technetium-99m sestamibi single photon emission tomography (SPECT) myocardial perfusion imaging (MPI) and its association with some clinical and laboratory parameters in an asymptomatic systemic lupus erythematosus (SLE) population. Materials and Methods : Twenty-one subjects with SLE and no suspected or documented coronary artery disease (CAD) accomplished myocardial perfusion imaging. Some SLE and CAD parameters were also evaluated in association with myocardial SPECT. Results: Twenty-one women with a diagnosis of SLE (mean age 36.9 ± 12.8) entered the study. All patients were in the low-risk category for CAD pretest; however, abnormal myocardial perfusion results were found in eight (38%) patients. Amongst the traditional CAD risk factors, there was a significant association between the presence of dyslipidemia and myocardial perfusion abnormalities (P= 0.047). However, we found no significant association between other traditional and SLE-specific risk factors. Conclusion: This study's significant finding was that asymptomatic CAD is common in SLE patients, even in those thought to be low risk for CAD and in the absence of cardiac symptoms. © The Author(s) 2010

Limnological study on Zarrineh River

Limnological studies of the Zarrineh River have been performed in order to identify physicochemical and biological characteristics of this river. Water samples from 14 sites along the river length were examined monthly during a year. The results indicated the river was polluted by Saghez and Miandoab Cities sewage to the extent of poly saprob, the extent of pollution at other sites was within the limits of oligo saprob or meso saprob. The results also showed that all dissolved and mineral compositions in this river was safe for drinking but iron concentration and water hardness in the terminal sites near the Urmia Lake are higher than EPA standards for drinking . This cannot, however, pose serious problem for warm water fish culture activities. Domestic sewage seem to be the most important pollution source to this river. Although the self-purification capacity of this river seem to be high but large number of polluting sites along the river exceed this capacity

Outcome of surgical treatment and the prognostic factors in full-thickness rotator cuff tear

Background: Rotator cuff tendon tear injury is one of the most frequently seen orthopaedic conditions, and surgical repair of rotator cuff tears is a common procedure. The purpose of the present study was to determine the results of full-thickness rotator cuff repair and to look for predictors of outcomes. Methods: we studied 27 patients (17 men and 10 women with a mean age of 57.7 years) who underwent open rotator cuff repair surgery for full-thickness tear between 2001 and 2005 at the Imam Khomeini Hospital and were subsequently followed-up for 6 and 12 months after surgery. The shoulder function was assessed by Constant classification and factors potentially associated with outcomes were Results: The mean of preoperative Constant score (CS) was 45.8 ± 14.1 after 12 months, 6 patients (22.2%) had good results and 21 patients (77.8%) had excellent result according to CS. Pain relief was generally satisfactory. Using multiple regression analysis, treatment was significantly correlated preoperative CS and acromio-humeral interval (AHI) however, no correlation was found between the result of the treatment and pretreatment atrophy, tear size, acromial morphology, preoperative symptom duration and age. Conclusion: In this study, a standard rotator cuff repair technique reduced pain severity and was associated with good results, however larger studies are necessary to define the long-term outcome of this procedure

Since at present there is no limitation in number of embryos being transferred in ART cycles in infertility centers in Iran, in order to evaluate the relationship between number of embryos transferred, pregnancy rates and multiple pregnancy, this study was performed in a referral university center."n"n Methods: In a cross sectional descriptive analytical study a total of 536 ART cycles in infertile patients treated at the Infertility Department of Vali-e-Asr Hospital & Vali-e-Asr Reproductive Health Research Center from October 1999- March 2003 were evaluated using a questionnaire dealing with the parameters affecting ART outcome."n"n Results: There was a total pregnancy rate of 21% with a multiple pregnancy rate of 12%. Increased age had a negative effect on pregnancy rate with a significant difference over 40 years (p<0.05). Pregnancy rate was higher with increased number of transferred embryos but it was only statistically significant when three versus two embryos were transferred (p<0.008). When more than three embryos transferred, although there was an increase in pregnancy rate, the difference was not statistically significant, but there was a significant increase in multiple pregnancy rate."n"n Conclusions: The maximum number of transferred embryos in ART cycles should not precede three embryos especially in age groups less than 40 and also when good quality embryos are available

Evaluation of Patients\' satisfaction with the services at Khatamolanbia Dental Clinic in Yazd,2011

Introduction: Considering patients' opinion is essential for the assessment of health care services. The aim of the present study was to survey patients' satisfaction with the services at Khatamolanbia Dental Clinic affiliated to Yazd University of Medical Sciences. Methods: This descriptive and cross-sectional study was carried out on 1380 randomly-selected patients who had referred to Khatamolanbia Dental Clinic. Data were gathered using phone interview and questionnaire. The questionnaire included some questions about demographic characteristics and viewpoints of the patients about dentistry, clinic, received treatment, dentist and clinical team. Data analysis were conducted using SPSS software. Results: The total mean score of the patients' satisfaction was 3 ± 0.02 out of 4. The highest level of satisfaction was related to guiding signs (99.6%) and hygiene and infection control (99.5%). The highest level of dissatisfaction was related to parking situation (90%) and treatment cost (21%). Totally, 90.2% of the subjects asserted they will choose this clinic again if they require treatment in the future. Conclusion: The patients' satisfaction was almost complete. Dissatisfaction about parking and high costs of some treatments are amendable regarding related authorities at University and the province and better contribution of insurers to dental services

Un enfoque integral para el manejo de las perforaciones endoscópicas agudas (con videos)

22 páginasThe only method to prevent iatrogenic luminal perforation at the time of endoscopy is the avoidance of endoscopic procedures. Luminal perforation is among the most feared adverse events of GI endoscopy, and the rationale for this is multifactorial: (1) it may carry significant morbidity and mortality; (2) perforation may not be remediable without a surgical procedure; (3) management of perforation requires a multidisciplinary approach, often beyond the endoscopist’s control; (4) perforation usually requires hospitalization, thus adding to the cost of care; and (5) perforation has medicolegal implications, including liability not only for the endoscopist but other providers involved with the case.1 In addition, the mere mention of the word perforation triggers alarm and panic among faculty and trainees alike, often with the assumption that all perforations require surgical management. In some cases, there may even be disagreement among involved specialties as to the approach toward perforation.El único método para prevenir la perforación luminal iatrogénica en el momento de la endoscopia es evitar los procedimientos endoscópicos. La perforación luminal es una de las más eventos adversos temidos de la endoscopia GI, y la justificación porque esto es multifactorial: (1) puede acarrear morbilidad y mortalidad significativas; (2) la perforación puede no ser remediable sin un procedimiento quirúrgico; (3) el manejo de la perforación requiere un enfoque multidisciplinario, a menudo más allá del control del endoscopista; (4) perforación generalmente requiere hospitalización, lo que aumenta el costo de la atención; y (5) la perforación tiene implicaciones médico-legales, incluida la responsabilidad no solo del endoscopista sino también de otros proveedores involucrados en el caso.1 Además, la mera mención de la palabra perforación provoca alarma y pánico entre profesores y aprendices por igual, a menudo con la suposición de que todas las perforaciones requieren manejo quirúrgico. En algunos casos, incluso puede haber desacuerdo entre los involucrados especialidades en cuanto al enfoque hacia la perforación
