Endometriosis is a multifocal gynecologic disorder during the fertility period in women. Magnetic resonance imaging (MRI) is an important diagnostic modality for this disease and can be used either alone or along with transvaginal ultrasonography.

This study aims to compare the accuracy of pelvis MRI in pelvic deep endometriosis with laparoscopic findings in women referred to Shahid Sadoughi hospital in one year.

This cross-sectional study was conducted on 40 women suspicious of endometriosis who referred to Shahid Sadoughi hospital, Yazd, Iran from November 2020-2021. Based on clinical findings and history, participants were referred to the imaging center for pelvic MRI. Finally, the results of MRI and diagnostic laparoscopy were compared with pathologic findings.

The sensitivity and specificity of MRI for pelvic endometriosis were 94.8% and 20%, respectively. Also, the positive predictive value and negative predictive value of MRI were 90.2% and 33.3%, respectively.

Laparoscopy is still the gold standard of endometriosis diagnosis, but MRI with susceptibility-weighted imaging sequence is the best noninvasive diagnostic method.

Children are the most important asset in any country. Since cardiovascular diseases are built up little by little from childhood, this study attempted to detect the relationship between psychological, spiritual, and social health conditions and cardiovascular risk factors in children. 

This study is a cross-sectional study performed on 1035 children aged 6-18 years by multi-stage random cluster sampling in 2016 in Yazd province of Iran. The lifestyle questionnaire (LSQ) was used to collect data. In addition, demographic information (i.e., age and sex) and cardiac risk factors were measured. Logistic regression and t-test were used to analyze the data. 

In this study, by increasing the mean score of psychological and spiritual health, fasting blood sugar (FBS) decreased significantly (OR = 0.14, 95% CI: 0.02-0.80, P trend = 0.003 and OR = 0.05, 95% CI: 0.01, -0.28, P trend = 0.013). Also, with increasing the mean score of spiritual health, body mass index (BMI) reduced significantly too. (OR = 0.35, 95% CI: 0.18-0.66, P trend = 0.014). However, social health failed to be significantly associated with cardiac risk factors. 

FBS in children aged 6-18 years is affected by psychological and spiritual health. BMI and the level of spiritual health also turned out to be inversely related. As a result, psychological and spiritual health dimensions should be improved to lower the risk factors for cardiovascular diseases in children aged 6-18 years.

Cardiovascular diseases are the most critical causes of mortality in the modern world. Additionally, most acute coronary events result from sudden thrombosis leading to atherosclerotic plaque rupture. Computerized tomography (CT) angiography can identify the characteristics and quantity of plaques. This study investigated the relationship between plaque and moderate coronary stenosis.

This study was a retrospective diagnostic study comprising 91 patients who had been referred to CT angiography at Afshar Hospital in Yazd City, Iran, from 2017 to 2018 and undergone coronary angiography CT while bearing moderate coronary artery stenosis. Using the CT report, location, plaque density, the extent of stenosis, and vein involved were all extracted and recorded. The patients were followed up for one year from the time of the CT scan using the MACE questionnaire. Ultimately, data was analyzed using SPSS software version 22 through Chi-square, Fisher's exact test, and t-test.

The results revealed the mean age of the patients to be 62.76±1.08 years; 39 (42.9%) women and 52 (57.1%) men. Based on the obtained results, the most common involved vessel, location of stenosis in CT angiography, and plate density included the left anterior descending artery with 75.8%, the middle part of the left anterior descending artery with 29.7%, mixed density with 54.9% and one segment with 62.6% frequency. Also, according to the significant adverse cardiac event (MACE) questionnaire results, the frequency distribution of cardiovascular events in the studied patients did not exhibit any evidence of cardiovascular events in the patients' one-year follow-up.

There was no evidence of cardiovascular events in the patients with moderate coronary artery stenosis during a 1-year follow-up.

The increasing frequency of computed tomography (CT) scans for a range of purposes, particularly pediatrics, has raised concerns regarding the population's radiation exposure and subsequent chances of cancers. This study aimed to estimate the effective doses of pediatrics radiation and induced cancer risks from five most common CT scan procedures in Yazd Province, Iran.

Data of pediatric patients from four age groups of ≤1, 1-5, 5-10, and 10-15 years old were retrospectively collected from 6 educational institutions located in diverse areas of Yazd Province. For each participant, the effective doses and REID (risk of exposure-induced death) rate were estimated by Impact Dose and PCXMC software, respectively. Then, the findings were reported by categorizing the patients regarding their effective diameter.

The effective doses and REID values did not show any significant differences among the studied age groups. The highest mean of effective dose was recorded for the scan of abdomen-pelvis (average ± standard deviation, 5.24±3.19 mSv) followed by chest (3.76±2.28 mSv), brain (1.25±1.07 mSv), and sinus (0.65±0.4 mSv) examinations. The highest REID was documented for chest scan (490±314 excess deaths in one million scans) followed by abdomen-pelvis procedure (404±280).

The radiation doses delivered to the pediatric patients and the associated fatal cancer risk with common CT procedures were comparably in the same range of the previous studies. Our findings can represent an estimation of the radiation-induced risks of CT scans and can be used for extending the knowledge of clinicians and researchers.

Incidental findings are presented in radiology reports. Many of these findings do not require further investigation; however, some require further investigation and repeated imaging. The aim of this study was to determine the frequency of incidental findings on CT scans of patients with head trauma from 2005 to 2015. This analytical cross-sectional study was conducted in years on 5,193 CT scan reports referred to Shahid Rahnemoun hospital in Yazd, Iran. The images were evaluated by consensus agreement of two radiologists. The relationship between age, sex and incidental findings was analyzed using the SPSS 20 software. A total of 5,193 subjects with a mean age of 34.16 ± 21.17 were examined. About 64% of cases were male. The frequency of incidental findings was 10.9%. The most common finding was calcification with a frequency of 3.3% and the least was Dandy Walker finding at 0.02%. There was no relationship between age, sex and the frequency of incidental findings. No significant trend was found between IFs frequency during ten years. The results of this study indicated that most incidental findings were related to benign findings, but also malignant findings were diagnosed.

Lymphangioleiomyomatosis (LAM) is a progressive lungs disease that affects women at reproductive years. Sirolimus inhibits mammalian target of rapamycin (mTOR) and its administration in past studies was hopeful in treatment of patients with LAM. The aim of this study was to evaluate sirolimus therapy on lung function in LAM patients. We conducted a trial to evaluate the effect of sirolimus on six patients with LAM who had severe or very severe obstructive lung disease, and one-year follow up. Maintenance level of Sirolimus was 10-15 ng/ml. Serial visits (including physical examination, evaluation of signs and symptoms of disease and adverse events due to treatment), spirometry, 6MWT done at baseline 3, 6, 9 and 12 months after. Spirometric parameters walk distance and O2 saturationbefore and after exercise at first and the end of treatment were measured. Four patients had TSC-LAM while the other 2 patients had S-LAM. The mean level of sirolimus was 13 ng/ml after one-year treatment. Mean FEV1 at enrollment and end of study was 1000cc (33% predict) and 1228cc (42% predict) respectively (P=0.674). The mean FVC at baseline and end of study was 1648cc (49% predict) and 1866cc (55% predict) (P=0.996). The mean FEV1/FVC at enrollment and the end of treatment was 58% and 62% respectively (P=0.753). The mean FEF25-75 at first and at the end of treatment was 16% and 26%, respectively (P=0.028). The mean walk distance in 6MWT at first and at the end of study was 315 meters (P=0.9). The mean percentage of O2 saturation at rest was 84% and 92% at first and at the end of study (P=0.104). In LAM patients, sirolimus has been shown stabilizeto or improve lung function, rest and exertional O2 saturation. Sirolimus was effective in LAM patients who had severe or very severe physiological disorders.

Diabetes mellitus is an important cause of heart failure deployment of left ventricular mechanical dyssynchrony. Nuclear cardiology phase analysis is an accurate, repeatable and reproducible modality for measurement LV dyssynchrony .The aim of study was assessment of phase analysis parameter including Standard deviation (SD) and band width (BW) in diabetic patient with normal MPI comparing with low risk population for CHD.
An analytical cross-sectional study was performed in clinical research development unit of Farshchian heart center, Hamedan University of Medical Sciences. We evaluated 165 patients who underwent SPECT MPI. Study population were 90 diabetic patients with normal MPI (sss The study results revealed no statistically significant differences in standard deviation (SD) and histogram band width (BW) of the phase analysis between diabetic patients and control group. Furthermore, in diabetic patient LVEF have a negative significant correlation to BW (r=-0.510) and SD (r=-0.422) but in control group there was no significant Pearson correlation is noticed.
Between diabetic patients and low likelihood person for CHD with normal MPI phase analysis parameter (BW and SD) shows no significant difference.

Orthosis and prosthesis is an expert knowledge in medical field including the design, fabrication and utilizing of orthosis and prosthesis. An orthosis is a device made of different types of material (plastic, aluminum, foam, leather, etc.) used externally on body segments to modify the structural or functional characteristics of musculoskeletal system to objectives such as: reducing pain, restriction or movements and redistribution of abnormal weight bearing pattern. Poor shoes fitting or abnormal friction may not be considered due to loss of senses in neuropathic diabetic patient. Untreating micro injuries may lead to ulceration and possibly even partial foot amputation. Deformities such as b:union:s, hammer toes, Charcot joint and also muscle weakness reported as secondary complications of neuropathy. It is suggested that in sub-acute stages of neuropathy with complication such as: Charcot joint, insensitive feet or muscles, orthotic prescription can be useful. The aim of this review was to assess the usefulness of therapeutic diabetic footwear (shoes) and insoles in treating diabetic foot.

Patellar instability is a multifactorial common knee pathology that has a high recurrence rate, and the symptoms continue and ultimately predispose the patient to chondromalacia and osteoarthritis. Tibial tuberosity-trochlear groove distance (TTTG) is very important in the assessment of patellofemoral joint instability. The purpose of this study was to report the normal value of TTTG in males and females in different age groups and to assess the reliability of MRI in measuring TTTG. All patients presenting with knee pain and normal examinations of the knee joint, with a normal MRI report, referring to Shahid Sadoughi hospital of Yazd, Iran, from April 2014 to September 2014, were included in the study. MR images were studied once by two radiologists and for the second time by one radiologist. Mean value of TTTG was reported for males and females and in three age groups. Intra- and inter-observer reliability was calculated. A total of 98 patients were eligible to evaluate during 6 months (68 male and 30 female). Mean TTTG was 10.9±2.5 mm in total, which was 10.8±2.8 mm and 11.3±2.3 mm in males and females, respectively (P>0.05). Mean TTTG in males ≤30 years, 30-50 years and, ≥51-year-old were 10.8±2.6 mm, 10.8±2.7 mm, and 10.8±2.6 mm, respectively; that was 12.1±3.4 mm, 11.4±1.9 mm, and 10.5±1.7 mm in females ≤30 years, 31-50 years and, ≥51-year-old, respectively (95% CI). The coefficient of variation was

In an ideal parallel-hole collimator, thickness of septal material should be sufficient to stop more than 95% of incident photons. However, some photons pass the septa without interaction or experience scattering before they reach the detector. In this study, we determined different contribution of collimator responses consist of geometrical response, septal penetration (SP) and scattering (SC) for low, medium and high energy collimators.
A point source of activity with common energies in diagnostic nuclear medicine and three different collimators were simulated using SIMIND Monte Carlo code.
For Low Energy High Resolution (LEHR) collimator, SP was increased from 7% in 140 keV to 30% in 167keV and more than 75% in energies higher than 296keV. SC also was increased from 4% in 98keV to more than 15% in energies higher than 167keV and reached to its maximum (26%) in 296keV. For Medium Energy All Purpose (MEAP) collimator, SP was suddenly increased from 6% in 186keV to 28% for 296keV and more than 50% for higher energies. SC was also increased from 4% in energies below 186keV to 15% in 296keV and about 30% for higher energies. For High Energy (HE) collimator, SP was about 20% for 364keV photons. SC was 15% for 364keV photons and only 65% of photons were geometrically collimated.
Our results showed that even by using nominally suitable collimators, there are considerable SC and SP that influence the quantitative accuracy of planar and SPECT images. The magnitude of geometrical response, SC and SP depend on collimator geometric structure and photons energy.

Duplex ultrasonography is a non-invasive, non-expensive screening test for carotid disease. Intima media thickness (IMT) is appropriate for atherosclerosis process diagnosis. Leukoaraisis (LA) increase the risk of cerebrovascular accident (CVA). LA patients need preventive medication for CVA. IMT is a non-invasive diagnostic and prognostic test in LA. The aim of this study was evaluate the carotid IMT and LA in diabetic patients as atherosclerosis surrogate marker.
The case-control study was done on 100 diabetic patients and 100 controls. They were selected by simple sampling method in Shaheed Sadoughi MRI unit. Two groups member were matched by age and sex. The patient’s information (age, sex, weight, height, past medical history, smoking history, ischemic heart disease(IHD), CVA and past medication) according the study checklist was collected. All statistical analysis was done by SPSS21.
Results Totally 200 patients were studied, 102 in normal group and 98 in diabetic group. The mean age of patients was 64.39 (±9.12) and 47% participants were male. There were no statistical differences between hypertension and hyperlipidemia frequency in two groups (P-value>0.05). The mean of left CIMT was 0.856 (±0.202) in normal and 0.962 (±171) in diabetics groups (P-value: 0.026). The mean of right CIMT was 0.853 (±0.215) in normal and 0.973 (±188) in diabetics groups (P-value: 0.024). The LA was significantly more prevalent in diabetic patients (P-value:0.001).
LA increases the risk of CVA and dementia. The LA pathology is unknown. The epidemiological studies revealed the age, diabetes, smoking and atherosclerosis are related with LA. Our findings showed that CIMT as an atherosclerosis marker was higher in LA patients than control group.

Atherosclerosis disease, inflammation and malnutrition have strong association with end stage renal disease (ESRD). Diabetes mellitus (DM) is the most commonly ESRD causes. Diabetic nephropathy (DN) could be associated with inflammation. Type 2 diabetic patients with advanced nephropathy show the highest levels of inflammatory markers. This study was designed to determine the association between malnutrition–inflammation–atherosclerosis (MIA complex) in Diabetic patients with peritoneal dialysis.
Fifty seven diabetic patients on peritoneal dialysis were investigated and demographic variables (age, gender, BMI and dialysis duration), Inflammatory markers (cholesterol, Albumin and CRP) were measured in routine protocol. CIMT (Carotid Intima-Media Thickness) and plaque number were evaluated by B-Mode ultrasonography (7.5 -10 MHZ probe) in supine position.
the mean age (Standard deviation) of patients was 51±17.3 years. The mean time on dialysis was 26.12 ±25.42 (range 4–120) months. The mean of IMT was 5.98±1.17 mm and mean of plaques were 1.80±2.01. Results of Analysis of variance (ANOVA) showed that older patients have more carotid plaques (P-Value= 0.000). There was a significant relation between serum albumin and number of plaques (P-Value=0.043). CIMT and number of plaque revealed significant correlation with age, serum albumin and dialysis duration (P Our findings showed, in diabetic patients on peritoneal dialysis, carotid atherosclerosis (CIMT and Number of plaque) is associated with some inflammation, malnutrition markers.

The risk of cardiac death in diabetic patients is 3 times more than non-diabetics. But it is not determined who need cardiac screening. About 41% of diabetic patients with silent ischemia are missed. the carotid intima-media thickness (CIMT) and ankel brachial index are two independent,simple and non invasive method in vascular complications diagnosis in diabetic patients.The aim of this study was to evaluate the assosiation of CIMT and ABI in prediction of silent myocardial ischemia in myocardial perfusion scintigraphy in Asymtomatic diabetic papulation.
This was an analytic cross-sectional study. The convenient sampling was used. About 114 patients with diabetics and no history and symptom of coronary artery disease (CAD) were included. Myocardial perfusion scan (MPI), CIMT and ABI were done. All of statistical analysis was done by SPSS-20.
Totally114 diabetic patients without cronary artery disease symptoms were included .About 66.7% were female. The mean age of patients was 53.8± 8.6 years old. About 50% (57) of patients were normal. The mean of CIMT was 0.93 ± 0.21 and mean ABI was 0.97 ± 0.11. Regarding the anlysis of variance (ANOVA) there were significant differences of mean CIMT and ABI between normal and moderate to severe ischemia in MPI.
Our findings showed that CIMT and ABI is significantly different between patients with and without ischemia. The CIMT and ABI are simple, non-invasive, and inexpensive tests that may be used to identify individuals who are at high risk of developing cardiovascular disease (diabetic patients).

Radiation therapy for breast cancer can induce myocardial capillary injury and increase cardiovascular morbidity and mortality. A prospective cohort was conducted to study the prevalence of myocardial perfusion abnormalities following radiation therapy of left sided breast cancer patients as compared to those with right–sided cancer. To minimize potential confounding factors, only those patients with low 10-year risk of coronary artery disease (based on Framingham risk scoring) were included. All patients were initially treated by modified radical mastectomy and then were managed by postoperative 3D Conformal Radiation Therapy (CRT) to the surgical bed with an additional 1-cm margin, delivered by 46-50 Gy (in 2 Gy daily fractions) over a 5-week course. The same dose-adjusted chemotherapy regimen (including anthracyclines, cyclophosphamide and taxol) was given to all patients. Six months after radiation therapy, all patients underwent cardiac SPECT for the evaluation of myocardial perfusion. A total of 71 patients with a mean age of 45.3±7.2 years [35 patients with leftsided breast cancer (exposed) and 36 patients with right-sided cancer (controls)] were enrolled. Dose-volume histogram (DVH) [showing the percentage of the heart exposed to >50% of radiation] was significantly higher in patients with left-sided breast cancer. Visual interpretation detected perfusion abnormalities in 42.9% of cases and 16.7% of controls (P=0.02, Odds ratio=1.46). In semiquantitative segmental analysis, only apical (28.6% versus 8.3%, P=0.03) and anterolateral (17.1% versus 2.8%, P=0.049) walls showed significantly reduced myocardial perfusion in the exposed group. Summed Stress Score (SSS) of>3 was observed in twelve cases (34.3%), while in five of the controls (13.9%),(Odds ratio 1.3). There was no significant difference between the groups regarding left ventricular ejection fraction. The risk of radiation induced myocardial perfusion abnormality in patients treated with CRT on the left hemi thorax is not low. It is reasonable to minimize the volume of the heart being in the field of radiation employing didactic radiation planning techniques. Also it is advisable to screen these patients with MPI-SPECT, even if they are clinically asymptomatic, as early diagnosis and treatment of silent ischemia may change the outcome.

The main aim of this study was to assess the prevalence of depression and general anxiety of the prisoners of war (POW) children. The study was also designed to compare the prevalence of depression and general anxiety amongst the POW’s children and normal adults, 20 years after the Iraq-Iran war. An analytic cross-sectional study carried out in June 2009 in Yazd (the centre of Yazd province in Iran). The target and sampled population were the children of the Iranian POW who lived in Yazd. One hundred and twenty six POW’s children, who were born before 1990 (date of father's freedom) were assessed. The duration of father’s captivation was between 29-119 months. Ninety-five subjects accepted to participate. General anxiety and major depression were assessed by Persian version of Hamilton Scale for anxiety and Beck depression Inventory. This study was a combination of the psychological interview and questionnaire. Ninety five of normal adult group were also paired matched and assessed. Among 126 POW’s children who fulfilled the inclusion criteria, the responsive rate was 75.3 % (95 participants).The mean age of participants was 28.3 (SD: 5.34).The father’s captivation duration were 29-119 months (mean: 79.2, SD: 21.6). The prevalence of depression and general anxiety amongst the POW’s children were 48.4% and 79%. The prevalence of depression and general anxiety among the paired group were 21.1% and 63.2%.The differences between two groups were significant (p =0.000). In this study we have demonstrated the prevalence of major depression and general anxiety in POW’s children and a normal adult sample. The differences of major depression and general anxiety among the two groups were significant.
