    BACKGROUND: Gastroparesis is characterized by delayed gastric emptying. This pathology is usually observed in patients with diabetes. One standard approach to quantitative assessment of gastric emptying is scintigraphic study. The aim of present study was to perform scintigraphic study of gastric emptying time in patient with diabetes and to find its correlation with patients’ characteristics. MATERIALS AND METHODS: Gastric emptying was assessed in 19 patients with type 2 diabetes (mean age of 61.04 ± 6.09 years) and 6 healthy volunteers. Characteristics of the patients were sex, age, duration of diabetes, blood sugar and serum HbA1c level. RESULTS: Results of present study revealed that gastric emptying half time was significantly larger in patients with type 2 diabetes as compared with healthy volunteers (P-value < 0.05). While correlation of sex, age, duration of diabetes and blood sugar with gastric emptying time was not statistically significant, HbA1c level had significant effect on gastric emptying time. CONCLUSION: Results of this prospective study indicated that level of serum HbA1c is an effecting factor on gastric emptying time in patients with type 2 diabetes; however, these preliminary findings should be validated in larger and well-designed studie

    False-positive defects on exercise 99mTc-sestamibi SPECT imaging, but not on dipyridamole 99mTc-sestamibi SPECT imaging, in a patient with right bundle branch block (RBBB)

    False-positive findings with myocardial perfusion imaging (MPI)have frequently been identified in the presence of left bundlebranch block (LBBB) and tend to lower the accuracy of MPI inindividuals with normal coronary angiographs. Pharmacologicstress is recognized as the preferred method for MPI in patientswith LBBB. In contrast, very few studies have evaluated the effectof right bundle branch block (RBBB) on MPI, and there isno consensus regarding the selection of pharmacologic versusexercise stress during MPI for the RBBB patient. In this study,we present a 45-year-old man with RBBB, who has a normal coronary artery angiography, but who showed abnormal myocardialperfusion with exercise MPI, and normal perfusion ondipyridamole MPI. The aim of the study is to stimulate awarenessthat the stress method selected for patients with RBBB canpotentially interfere with the accuracy of the data

    Assessment of Gastric Accommodation in Patients with Functional Dyspepsia by 99mTc-Pertechtenate Single Photon Emission Computed Tomography Imaging: Practical but not Widely Accepted

    Objective: Impaired gastric accommodation is one of the main symptoms in patients with functional dyspepsia. The aim of the present study was to assess gastric accommodation in patients with functional dyspepsia using single photon emission computed tomography (SPECT) imaging. Methods: Twenty-four patients with functional dyspepsia and 50 healthy volunteers as control group were enrolled in this study. All participants were given 5 mCi 99mTc-pertechtenate intravenously, served with a low fat meal, and underwent SPECT scanning 20 minutes after the meal. Results: Based on the scintigraphic data, gastric volumes were found to be significantly increased after food ingestion in both patient and control groups. We also found that while there was no significant difference between patient and control groups in terms of fasting gastric volumes, postprandial gastric volume was significantly lower in patients as compared to healthy individuals (p<0.05). Conclusion: Measuring gastric volume by using SPECT can be a valuable method in the detection of functional dyspepsia and in differentiation of this entity from other organic disorders

    The association of increased stomach wall radiotracer uptake with prolonged use of Omeprazole capsules on myocardial perfusion imaging (MPI) using 99mTc-sestamibi SPECT

    Get PDF
    Myocardial perfusion imaging (MPI) is widely used in routinepractice for diagnosis and risk stratification of coronary arterydisease (CAD). Intense curvilinear activity in the stomach wallof a patient was seen on MPI raw data. This phenomenon was completely dissimilar to the familiar intraluminal gastricreflux of sestamibi. This observed activity could have resultedin false-positive or false-negative artifacts — and inaccurate diagnosis — of the inferior wall of the left ventricle after MPI processing. On further exploration, the current researchers found that the patient had a history of 10-year Omeprazole capsule consumption. The authors present this infrequent case of intense stomach uptake to stress the related clinical and diagnostic implications with the aim to stimulate acute awareness of possible, unexpected infringements on image quality that could potentially interfere with accurate interpretation of the data

    BACKGROUND: Once considered as the main public health problem in developed countries, obesity has become a major problem throughout the world and developing countries, like Iran, are joining the global obesity pandemic. We determined the prevalence of overweight, obesity, and hypertension in a large cohort of Iranians and compared age-adjusted rates with the rates in the US. METHODS: Golestan Cohort Study is a population-based study of 8,998 men and women, aged 35-81 years, from urban and rural areas. Anthropometric parameters were measured by interviewers. Prevalence rates were directly adjusted to the 2000 United States standard population. RESULTS: The age-adjusted prevalence rates of overweight (BMI ≥ 25 kg/m2) and obesity (BMI ≥ 30 kg/m2) in this Iranian population were 62.2% and 28.0%, respectively. Both overweight and obesity were more common in women than men. Age-adjusted prevalence of overweight was significantly higher in Iranian women compared to the American women (68.6% vs. 61.6%), while the age-adjusted prevalence of obesity is closer in these two populations (34.9% vs. 33.2%). Iranian men—compared to American men—had significantly lower age-adjusted prevalence of overweight (53.7% vs. 68.8%) and obesity (16.2% vs. 27.5%). Age-adjusted prevalence of hypertension was higher in Iranian women than American women (35.7% vs. 30.5%). Diabetes mellitus was reported in 6.2% of participants. Mean waist-to-hip ratio (WHR) among women was 0.96. Smoking rates in men and women were 33.2% and 2.2%, respectively. CONCLUSION: The prevalence of obesity, overweight, and hypertension in Iran is as high as the US. However, Iranian women are more obese than American women and Iranian men are less obese than their American counterparts. This discrepancy might be due to the low rate of smoking among Iranian women. Iranian women have higher mean WHR than what WHO has defined in 19 other populations

    Background & objective: One of the common purposes of medical research is Determination of effective factors on the occurrence of event. Due to the interaction of risk factors regression models, discriminant analysis and classification procedures used. Uses of these models require making the assumption which in the medical data isn’t usually established. Therefore, alternative methods must be used. According to diversification of risk factors for of esophageal cancer, the purpose of this article is the Introduction and application of classification and regression tree for determination of risk factor for esophageal cancer in Golestan province.Methods: Data of this article gathered from case-control study. Case group contain all confirmed cases of esophageal cancer that consist of 90 male and 60 female subjects in Golestan province during one year. Two control groups were considered for each case. Control groups were selected from family of patients and neighbors and matched for age, sex, ethnic and place of residence. Data was analyzed with classification and regression tree model and by using of R software. Gini criterion was used for selection of best splitting in each node and ROC surveyed accuracy of CRT model.Results: (ethnic factors) can be effective in esophageal cancer occurrences.Results of Classification tree model showed that exposure to CT and X-ray dye (socio-environmental factors), unwashed hands after defecation, history of smoking (lifestyle factors) and family history of cancerConclusion: models results` interpretation are two essential beneficiary of these models which can use in medical sciences.Tree models don’t require the establishment of no default for making model and feasibility of tre

    Abstract Background The reported positive association between opiatic drug use during pregnancy and adverse pregnancy outcomes might be confounded by other factors related to high-risk behaviors, including the use of other harmful substances. In rural areas of Iran, opium use during pregnancy is relatively common among women who otherwise do not have a hazardous lifestyle, which reduces the risk of residual confounding and increasing the possibility to identify its effects. We aimed to examine the association of antenatal exposure to opium with risks of small for gestational age, short birth length, and small head circumference at birth. Method In this cohort study in the rural area of the Golestan province, Iran, we randomly selected 920 women who were exposed to opium during pregnancy and 920 unexposed women during 2008–2010. Log-binomial regression was used to estimate risk ratios (RR) and 95% confidence intervals (CI) for the associations between prenatal exposure to opium and risks of small for gestational age, short birth length, and small head circumference at birth. Results Compared with non-use of opium and tobacco during pregnancy, using opium only and dual use of opium and tobacco were associated with increased risks of small for gestational age at births (RR = 1.71; 95% CI 1.34–2.18 and RR = 1.62; 95% CI 1.13–2.30, respectively). Compared with non-use of opium and tobacco, exposure to only opium or dual use of opium and tobacco were also associated with more than doubled increased risks of short birth length, and small head circumference in term infants. Conclusion Maternal opium use during pregnancy is associated with increased risks of giving birth to a small for gestational age infant, as well as a term infant with short birth length or small head circumference

    Background and Objective: Considering the importance of coverage and quality of data in Golestan population-based Cancer Registry (GPCR), northern Iran. This study was conducted to determine the effect of the referral of cancer patients to medical centers outside Golestan province on the coverage of the population-based cancer registry program. Methods: This descriptive-analytic study was performed on all cancer patients registered in the diagnostic centers of Golestan province, northern Iran during 2008-10. Data of patients referred to the centers of the province from the bank of the Golestan province cancer registry program and data of patients referred to the centers outside the province were received from the Ministry of Health Department of Cancer. Data were analyzed using the record linkage method. Results: A total of 6083 new cases of cancer were registered in Golestan province. According to the cancer data, 678 (11%) of them were referred to outside of Golestan province centers. 343 of these 678 patients (50.6%) were found as duplicate records between the two datasets. The most frequent cases were gastric cancers (70.4%), breast (63.5%) and esophagus (62.5%). Conclusion: This study suggested that referrals of cancer patients to centers outside the Golestan province may result in an underestimation of about 5% in GPCR. This level of underestimation seems to have no considerable effects on completeness and quality of data in the GPCR
