Mehr Aein A, Davoodi S, Madani Givi M,
Volume 61, Issue 6 (15 2003)
Abstract
The aim of this study was to compare the effects of intraoperative autotransfusion and tranexamic acid on post-operative bleeding and need for allogeneic transfusion.
Materials and Methods: In a prospective, randomized study, 200 patients undergoing CABG allocated into two groups:
□ AT group = 100 patients received 1-2 units (300-450cc) autologous blood after termination of CPB D TX group = 100 patients received tranexamic acid, 15mg/kg before the injection of heparin and 15mg/kg after protamin injection Postoperative bleeding, transfusions, complications, ICU stay and hospital stay were recorded.
Results: The postoperative bleeding was lower in TX group (600 ml) than in AT group (1100 ml) (P <0.001). The rates of transfused patients in AT and TX groups were 72% and 65%. Patients in the AT group received more whole blood (2.82 units per patient vs. 1.93 units in TX group) (P<0.01). The numbers of FFP units administered per patient in AT and TX groups were 3.08 and 2.38 (P <0.01). In TX group, ICU stays and hospital stays were 0.8, 5.4 days (vs. 1.2s, 6.7days in AT group). In AT group, there were 2 transient renal dysfunctions and two re-operations. There was no difference between all groups regarding to neurological dysfunction and coagulopathy. There is no hospital mortality in all groups.
Conclusion: Tranexamic acid in comparison with intra-operative autotransfusion effectively reduces postoperative complications and allogeneic transfusions in CABG. In addition this technique due to shorter ICU and hospital stay is cost- effective.

Volume 62, Issue 3 (11 2004)
Abstract

Background: Infants and children present with a wide range of congenital chest wall deformities which have both physiologic psychologic consequences and are often associated with other abnormalities. Surgical intervention offers excellent cosmetic results with minimal morbidity and mortality. In order to investigation of chest wall deformities, and surgical results, this study was performed.

Materials and Methods: A descriptive study on existing data on 60 consecutive patients with chest wall deformity during 10 years carried out. Patient's characteristics such as age, gender, signs and symptoms type of operation, associated disorder, syndrome, and surgical complications were considered.

Results: Pectus excavatum 60% and pectus carinatum 30% Poland syn 6.7% 9 sternal cleft 3.2. Inpectus, M/F: Was 3/1 and others were 1:1. Age of admission 4 to 27 years 13.4±6.82) and association syndromes were, turner, Morgue and marfan, most patients were operated in delayed time (75) and hence, scoliosis was common than others.

Conclusion: Pectus excavatum was the most common deformity and if scoliosis was prominent and most operation was done in old age but surgical result was excellent no anyone expired and complication was a little. So we recommended that all of the chest deformities must be operated in anytime.

Volume 66, Issue 11 (3 2009)
Abstract

Background: Trauma is a common problem in the world, predominately affecting young adults. Considering the high mortality rate in patients suffering from thoracic trauma, the condition is considered to be extremely important. The purpose of this study was to evaluate the prevalence and the epidemiology of chest trauma as well as the severity of the resulted injury in Tehran, Iran.

Methods: This prospective, descriptive study was conducted on patients admitted to three medical centers in Tehran during June 1997 and 1998 due to chest trauma. The data on the demographic information of the patients, the mechanism of the trauma and the severity of the injury were collected and analyzed.

Results: Three hundred forty two patients were admitted to hospital due to thoracic trauma the majority of which were male adults. Blunt trauma especially secondary to motor vehicle accidents were the most frequent cause of chest injury in the studied patients. In 280(82%) of the cases, another form of trauma was also reported. Chest wall injury was the most common type of thoracic trauma in these patients. The trauma was reported to be mild in 181(53%) of the patients (ISS<7). Only 42(12%) patients required surgical intervention. The overall mortality rate was 14% which was reported to be ISS- related.

Conclusion: Chest injury is quite prevalent among trauma patients and is associated with other injuries in a considerable number of the patients. This type of trauma is associated with a high mortality rate among elderly and therefore needs special attention and care.

Volume 70, Issue 3 (4 2012)
Abstract

Background: Carotid endarterectomy (CEA) is a standard method for patient with significant carotid stenosis but direct surgical repair via carotid endarterectomy may not be a good option in some patients because of the overall health status that may make the surgery too risky. Carotid angioplasty and stenting (CAS), is a relatively new procedure for the treatment of carotid artery disease in patients who may not be fit enough to undergo surgery. In this investigation, we determined short- and long-term outcomes of stent angioplasty in high-risk patients for whom the risk of perioperative morbidity and mortality is high.

Methods: We have followed 82 consecutive symptomatic patients with a ≥50% and asymptomatic patients with a ≥70%- 80% carotid stenosis within 15.9 months of angioplasty and stenting in Baqiyatallah and Jamaran hospitals from 2008-2010. All the patients were considered poor surgical candidates by experienced surgeons and anesthesiologists upon pre-surgical consultation.

Results: This descriptive cross-sectional study was performed on 28 women and 54 men with a mean age of 69.7±9.2 years. The procedure was technically successful in 79 (96.3%) cases. There were 6 (7.3%) deaths, 5 (6.1%) strokes, 4 (4.9%) MIs and 4 (4.9%) TIAs during the follow-up period.

Conclusion: The clinical results during the short available follow-up period suggested stent angioplasty to be useful, effective, reliable and safe in the treatment of significant cervical carotid stenosis in high-risk patients. Further analytical investigations with longer follow-up periods for predicting risk factors are recommended.

Volume 71, Issue 6 (September 2013)
Abstract
Background: The request for lumbosacral MRI in Iran  based on previous studies is high (almost half of all MRI cases), so, our study is concerned with investigating the necessity of lumbosacral MRI request in patients with low back pain that is covered by  complementary health insurance in Tehran through comparing  MRI practice with valid guidelines.
Methods: Information of 274 complementary insured patients at Dana Insurance Company in Tehran, who had undergone low back MRI was studied. A portion of information in the questionnaire including age, sex, the physician’s field of specialty, and MRI report, was derived from the medical records. Other information based on guidelines indications, including duration of the prolonged back pain, record of associated infection, malignancy or trauma, saddle anesthesia, lower limb motor deficit and incontinence of urine or feces, was elicited from patients orally.
Results: Males represented 35% and females 65% of patients. Also, males were on average 10 years younger than females. Over 90% of MRI scans were requested by three fields of specialty (orthopedic, neurosurgery and neurology). Considering the indications of lumbar spine MRI request (prolonged back pain of more than one month duration, incontinence of urine or feces, lower limb motor deficit, saddle anesthesia, recent related trauma, infection and malignancy), approximately 20% of lumbar spine MRI scans were prescribed in accordance with guidelines.
Conclusion: Out of every five cases of lumbar spine MRI, four cases were not requested based on guidelines, suggesting needs for local guideline design and revising the manner in which MRI scans are prescribed for low back pain in complementary health insured patients in Tehran.

Volume 71, Issue 9 (December 2013)
Abstract
Background: Adipokines are peptides secreted by adipose tissue that affect whole-body energy metabolism. Exercise training exerts beneficial effects on adipose tissue. However, less is known regarding visfatin’s, IL-6 & TNF-α response to an interval acute training. Therefore, we investigated the effects of acute interval exercise on plasma visfatin, TNF-α and IL-6 levels, in healthy female rats. Furthermore, correlate between changes probably these factors were also assessed.
Methods: This study was conducted experimentally. Forty five female sprague dawley rat were randomly divided into three groups: pre test (n= 15), treadmill exercise (n= 15) and sedentary controls (n= 15). The acute alternative exercise consisted of treadmill running: 3 session/ week for 8 week. The changes of plasma IL-6, TNF-α and Visfatin levels were measured by ELISA analysis. Data were analyzed using analysis of variance with measures (ANOVA) and post hoc Tukey test.
Results: Acute interval treadmill exercise led to significant decreases in visfatin (P= 0/036), IL-6 (P= 0/009) and TNF-α (P= 0/022) plasma levels between the groups. Also, this study no significant correlations between the changes in adipokines were observed.
Conclusion: Decreased levels of TNF-α and IL-6 correlated with intensity and duration exercise. Furthermore, probably there were some factors except weight decreasing that affects on visfatin decrease. Therefore, the reduction of this factor may cause in preventing metabolic disease.

Abstract
Background: In Nov 2013, the instruction for controlling high cholesterol has been released by the American College of Cardiology (ACC) and the American Heart Association (AHA) which need to be assessed in the different communities. Methods: Of total 6275 individual aged 40-75 years who entered at the Tehran Lipids and Glucose Study from March 1999 to 20 March 2010 in first examination cycle, 5153 with the median follow-up of more than ten years were eligible to enter in this study. The 10-year risk of hard cardiovascular disease (Hard CVD) for Statin therapy based on ACC/AHA clinical guideline was calculated and this risk was calculated for each subgroup of the guideline who recommended for statin therapy comparing to the risk in individuals with prevalent CVD. Results: Of nearly 6.5 million urban population of Iran (according to the 1996 census) about 4 million individuals (2.55 million men and 1.4 million women) were eligible for statin therapy. With respect to the urban population growth from the 1996 to the 2011 census (about 2.5 percent increases) the number of individuals for receiving statin increased by 50% (5 million men and 3 million women). Also, the risk in non-diabetic men with calculated risk of 5-7.5% and diabetic women with calculated risk of <5% for hard CVD was lower than 0.2. By removing these people from total eligible population, the burden of statin therapy will reduced about 8% which is about 540.752 persons, according to the Census 1996 and 1.155.079 individuals based on the census 2011. Conclusion: The new guideline of ACC/AHA for statin therapy is relatively reasonable except for some subgroups. To reduce the burden of medical expenses, statin prescription can be ignored by physicians in these subgroups. Of course further research is required to calculate the net benefit for estimating the clinical usefulness of statin therapy in recommended guideline subgroups.

Volume 73, Issue 4 (July 2015)
Abstract
Background: Antimicrobial resistance is a growing problem in many bacterial pathogens and is of particular concern for hospital-acquired nosocomial infections. Klebsiella pneumonia is an important cause of nosocomial infections has rapidly become the most common extended spectrum beta-lactamases (ESBLs) producing organism. ESBL are defined as the enzymes capable of hydrolyzing oxyimino-cephalosporins. The aim of this study was to compare phenotypic detection of ESBL using two phenotypically method among the clinical isolates of Klebsiella pneumoniae. Methods: In this cross-sectional study a total of 144 isolates from clinical samples Urine, sputum, wound, blood, throat and body fluids isolated and identified as K. pneumoniae in a teaching hospitals in Shiraz within a six months period from December 2012 to May 2013. Antibacterial susceptibility test performed to 14 antibiotics by the disk diffusion method according to CLSI guideline and then isolates that were resistant to at least one of the beta-lactam antibiotics evaluated for the production of beta-lactamase enzymes by using E-test ESBL and combined disk method. Results: Totally 38 (26.3%) isolates produced ESBLs. All ESBL producing isolates were susceptible to imipenem and meropenem and resistant to aztreonam. The highest antibiotic resistance was observed for amoxicilin (100%) and the lowest antibiotic resistance was observed for meropenem (9.7%). The number of 38 (100%) isolates were identified as ESBL producer by using E-test ESBL ceftazidime. It was while using the combined disks ceftazidime/clavulanic acid, cefotaxime/clavulanic acid and cefpodoxime/clavulanic acid, respectively 35 (92.1%), 34 (89.4%) and 31 (81.5%) of isolates identified as beta-lactamase producing isolates. Conclusion: Considering the high prevalence of bacteria producing ESBL, screening for infections caused by ESBL-producing isolates may be lead to the most effective antibiotics therapies.

Abstract

Background: Breast cancer is the most common cancer among females in the world. Identifying the nutrients that modify the risk of the disease is one of the key strategies for improving the quality of life and reducing treatment costs. Epidemiological studies support the role of macronutrients and vitamins involved in one carbon metabolism in the etiology of the disease. This study aimed in investigation of the relationship between the intake of macronutrients and vitamins involved in one carbon metabolism with breast cancer risk.

Methods: This case-control hospital base study was conducted at Shohada Hospital, Tehran from April to February 2015. Demographic data, physical activity level and nutrients’ intake from diet and supplements were collected through interview from 151 cases and 154 controls. Dietary intake was assessed by a valid and reliable 168-item semi-quantitative food frequency questionnaire. Then intake of macronutrients and B vitamins was assessed by Nutritionist 4 software (First Databank Inc., CA, USA). Comparing categorical variables between the two groups was done by Chi-squared test and the relationship between intake of studied nutrients and risk of breast cancer was determined using logistic regression test.

Results: There were no difference in age, menarche age, menopause age, body mass index (BMI), number of live births between two groups. But the difference in physical activity, energy intake, marital status, educational level, occupation, oral contraceptives use was significant (P< 0.001). After modifying the effects of confounding variables, the risk of breast cancer was significantly lower in the highest intake quartile category relative to the lowest quartile category for total protein, total fiber, intake of vitamins B2, B6, B12 and folate (Ptrend< 0.001). Before modifying the effects of confounding variables, the risk of breast cancer was significantly higher in the highest intake quartile category relative to the lowest quartile category for carbohydrate and fat; but after modifying the effects of confounding variables, results were not significant.

Conclusion: The results showed that high intake of protein, fiber, vitamins B2, B6, B12 and folate are associated with lower risk of breast cancer.

Volume 75, Issue 5 (August 2017)
Abstract
Background: Spasticity is a clinical deficit of upper motor neurons lesions that presented immediately or at delayed times after lesions and occurs in about 38% of stroke patients. Extracorporeal shock wave therapy (ESWT) has been recently reported as a safe and effective method for reducing spasticity in stroke patients. In the present study, we sought to investigate the impact of the ESWT on post stroke spasticity using a meta-analysis method.
Methods: All primary reports of spasticity indexed in PubMed, MEDLINE, Science Direct, Scopus and search engine of Google Scholar from January 2000 to December 2016 were searched. The following terms were used as keywords: Spasticity, muscle hypertonicity, ESWT, stroke and hemiplegia. Any report was included if it met the following criteria: involving clinical trials, full-version availability, and being written in english. Two reviewers selected articles independently and reviewed the studies considering quality and eligibility, and then they extracted general information on objectives, design, participants, and outcomes. The methodologic quality of each study was assessed using the Pedro Scale. In the statistical analyses, we considered two outcomes; Modified Ashworth scale (MAS) grade and passive rang of movement (PROM). The meta-analysis was done using random effect model in Stata, version 11 (Stata Corp., TX, USA).
Results: Eleven studies within a total of 261 patients were included in this review. In seven studies the shock waves were applied to the upper limb muscles, and in four other studies, the effects of ESWT on the spasticity of the lower limb muscles were assessed. Immediately after applying the ESW, MAS grade was significantly decreased in comparison to the baseline values. (Standardized mean difference [SMD], -1.62; 95% confidence interval [CI], -2.2 to -1.04). The PROM was significantly increased immediately after ESWT in comparison to the baseline values (SMD, 3.23; CI 95%, 1.35 to 5.12).
Conclusion: The results of this study showed that ESWT can immediately improve the spasticity and increased PROM, but it seems that the mechanism of action of shock waves on spasticity is still unclear. Further clinical trial studies with higher methodological quality should be recommended.

Volume 75, Issue 10 (January 2018)
Abstract
The members of Mycobacterium tuberculosis complex (MTBC) known as causative agents of human tuberculosis. Tuberculosis infection is one of the most important occupational risks for healthcare workers (HCWs) in most countries, such as Iran. In general, there are two types of tuberculosis, they include: latent infection and active TB. Latent tuberculosis infection (LTBI) means: a patient is infected with Mycobacterium tuberculosis but, the patient does not have active tuberculosis, clinical symptoms and radiological findings. According to studies, TB infection from patients to health care workers, depending on geographic region and economic situation is two to five times more than general population. The lowest incidence and the highest rates of LTBI prevalence among HCWs were 7% in Mashhad and 82.8% in Zahedan respectively. The risk factor acquisition of TB infection was a significant relationship with certain hospital wards (lung disease unit, laboratory, etc.), Increasing age and duration of employment. And results of this study show that TB is a significant problem among HCWs in Iran. Infection control and personal protective measures with training programs to patients and HCW is required to reduce the occupational risk of TB. Early detection of Mycobacterium tuberculosis and prevention treatment in people with latent TB are key elements in control of tuberculosis. Until now, different methods for detection of latent tuberculosis infection has been introduced that are not gold standard none of them. However, the most important methods, tuberculin skin test and the tests that based on measuring the production of interferon gamma are recommended, but each one of them has advantages and disadvantages. However, in all the articles of the tuberculin skin test is used for screening and early diagnosis of latent tuberculosis infection. So, the aim of this study was to Incidence and prevalence of latent tuberculosis infection in health care workers and risk factors, advantages and disadvantages of each method for diagnosis of latent tuberculosis infection and evaluate different strategies for reducing the incidence of latent tuberculosis infection in health care workers.

Abstract
Background: The most common cause of death in thalassemic patients is cardiac involvement especially cardiomyopathy. If the early stages of heart disease in people with thalassemia are diagnosed, mortality of patients reduced significantly. In this case-control study we compare the clinical symptoms, signs and para-clinic finding in thalassemia patients with control group.
Methods: In this case-control study, thalassemia patients who had visited in special clinic of Vali-e-Asr hospital of Birjand University Medical Sciences during January of 2013 to May of 2014 compared with normal subjects. They matched by age and sex. After explaining the aims of the project, the written consent was received from both groups. Clinical examinations including history taking and auscultation of heart and lungs were performed by Pediatrician. Moreover, using the standard methods, the measurement of height, weight and blood pressure were performed. In following, electrocardiography (ECG) was taken in both groups. Also, both groups underwent transthoracic echocardiography by one cardiologist.
Results: 42 thalassemia patients and 42 healthy subjects was compared in this study. Dyspnea was the only different symptom in the two groups. (23.8% in case and 4.8% in control P=0.01) In physical examination respiratory rate (RR) is only higher in patients with thalassemia that controls, but heart rate (HR), abnormal heart and lung sounds were not different significantly between two groups. In ECG, PR interval and QTc interval in patients with thalassemia was longer than healthy subject. In echocardiography, ejection fraction was lower but left ventricular end-diastolic diameter (LVEDD), left ventricular end-systolic diameter (LVESD) and size of the right ventricle and pulmonary artery pressure (PAP) was significantly higher than those in the control group.
Conclusion: According the result of this study, dyspnea was higher in patients with thalassemia from normal subjects and PR interval and QT interval was longer in thalassemic patients. As well as the size of the left ventricle, size of right ventricle, pulmonary artery pressure were higher than normal population. Also, LV ejection fraction was lower in thalassemia than normal population.

Abstract
Immunotoxins such as pseudomonas exotoxin are Molecules with a unique structure like toxin-antibody part. These immunotoxins are two functional which crossing the cell membrane and enters the target cell and destroy the cell. Toxin-based treatments are a widespread research field and can have broad applications in the biology and public health. Immunotoxins act selectively against cancer cells and have a good potential for detecting and targeting cancer cells. Specific immunotoxins to target immune cells due to the selection type antibody and antibodies are responsible for the identification of the target cells. Cancer is becoming a major cause of death in most developed countries. In order to have a strong factor in cancer repression, that agent must target the cancer cells directly and specifically. Often, but not always, immunotoxins are produced for disabling and killing cancer cells, that this issue is one of new therapeutic approaches in recently. Clinical aims to designing and create new cancer therapies focused with this approach, a lot of information about the toxin and intracellular pathways have been obtained. So, toxins in medicine are useful for the treatment of human disease and study of professional cellular functions. So, immunotoxins have a high potential for cancer treatment. Other applications of immunotoxins, including immune system regulation and treatment of viral diseases and parasites diseases. More research is needed to improve the immunotoxin effects and to reduce their side effects. On the whole, with design creative, clever and experienced programs, many human diseases, particularly cancers can be in a short period of time and faster than other methods of treatment that the treatment of long, to be treated. Following the design and implementation of clinical trials, the effects of immunotoxins on animal tumorigenic models were performed. In fact, in this study, we focus on the use of protein-bound toxins with bacterial and herbal sources and more specifically Pseudomonas immunotoxins which attached to antibodies to target cancer cells.

Abstract
Background: The average age of women with breast cancer in Iran is at least 10 years lower in comparison to developed countries and the incidence of the disease in Iranian women is on a rise. According to studies, diets that are diverse in food groups can play a role in protecting against chronic diseases including cardiovascular diseases and cancer. Diet diversity score is an indicator used to measure diversity between and within food groups. This study aimed to assess the relationship between diet diversity score and breast cancer risk.
Methods: This case-control study was carried out from April 2014 to February 2015 at Shohada Hospital in Tajrish, Tehran. Demographic and anthropometric data of 298 participants including 149 breast cancer cases and 149 apparently healthy women were collected. A valid food frequency questionnaire containing 168 food items was completed to assess usual dietary intake through face to face interviews. Energy was calculated using Nutritionist 4 software (First Databank Inc., Hearst Corp., San Bruno, CA, USA) and diet diversity score was calculated using five food group scoring. Odds ratios with 95% confidence intervals were obtained using logistic regression test to evaluate the association between breast cancer risk and diet diversity score tertiles.
Results: There was no significant difference in weight, height, body mass index between the two groups, but physical activity level and daily energy intake showed a significant difference (P<0.001). After adjusting for the effect of confounding variables including energy, body mass index, physical activity, menopause status, family history of breast cancer, contraceptive use, number of pregnancy, age of menarche and smoking, the risk for developing breast cancer was 86% lower in those in the highest tertile of diet diversity score compared to those in the first tertile (OR=0.14, 95% CI=0.06-0.31). An inverse and significant association was found between breast cancer risk and diversity scores of fruits and milk groups (P<0.001).
Conclusion: Higher diet diversity score is associated with reduced risk of breast cancer.

Davood Azimpour , Nahid Tahan ,
Volume 77, Issue 4 (July 2019)
Abstract
Background: Spasticity is a common motor impairment in patients with stroke that not only has a negative impact on the patient’s quality of life but also has high economic burdens for society. Recently the application of shock wave therapy has attracted considerable attention as a safe and effective method in treatment of spasticity. The objective of the present study was to investigate the effect of application shock wave on spasticity of quadriceps femoris and triceps surae muscles in patients with stroke.
Methods: This was a quasi-experimental study on 15 stroke patients which were selected according to inclusion criteria between September 2016 and May 2017. This study was approved by the Ethics Committee of Shahid Beheshti University of Medical Sciences, Iran. The intervention included one session placebo shock wave and three sessions of true shock wave. Level of the spasticity was measured at quadriceps and gastrocnemius muscles by Ashworth scale (AS) and passive range of motion (PROM) of the knee and ankle joints was recorded by a manual goniometer (Enraf-Nonius Corp., Delft, Netherlands). Participants were assessed at baseline, after the placebo shock wave, after the final session of active shock wave and 4 weeks after the last treatment.
Results: Placebo shock wave had not significant effect on grade of AS of spastic muscles as well as PROM of knee and ankle joints. True shock wave induced a statistically significant reduction in AS of triceps surae and quadriceps femoris muscles and improvement of PROM of knee and ankle joints. The reduction in AS of triceps surae and improvement of ROM ankle joint continued 4 weeks after the last treatment.  However, after 4 weeks, there was a significant reduction in the PROM of knee joint compared to the last session.
Conclusion: Three sessions shock wave therapy can reduce the tone of triceps surae and quadriceps muscles and improved the passive range of motion in the knee and ankle joints for up to 4 weeks, but these effects were not stable on the PROM knee joint.

Abstract
Background: Human papillomavirus (HPV) is a large group of DNA viruses that cause skin and mucosal warts. Zinc is used in the treatment of skin diseases. Zinc has been used in the treatment of various skin and systemic diseases. Warts are benign proliferation of the skin and mucosa. The prevalence of skin warts is higher in children and its peak is in adolescence and then decreases with age. Some species of HPV can cause malignancies. The effective role of zinc in the treatment of warts has recently been discussed. This study aimed to evaluate the serum zinc levels in patients with cutaneous warts compared to healthy controls.
Methods: This case-control study was performed on patients, aged 18 to 60 years old, referred to the Dermatology Clinic of Bo’Ali Sina and Razi Hospitals, Mazandaran Province in, Iran, from April to March 2016. Serum zinc level and severity of disease were assessed in case and control groups. Data were analyzed by SPSS software, version 22 (SPSS Inc., Chicago, IL, USA).
Results: A total of 94 subjects (47 in the case and control group) entered the study. The mean age of the case group was 26.40±9.33 years and in the control group 28.32±7.35 years. The gender status was 42 (44.7%) male and 52 (56.3%) female. Single and married were 63.8% and 36.2%, respectively. The mean zinc level in patients with cutaneous wart was 82 and the control group was 85.65. The mean number of warts was 5.09±6.33. The most frequent site of lesions were on the hands and foot with 48.93% and 40.42%, respectively, and the face (3.2%) had the lowest rate. Almost half of the patients were affected by the disease for 12 to 18 months. There was no significant relationship between age, sex, and severity of disease with serum zinc level (P>0.05). Serum zinc level was significantly associated with the duration of warts involvement (P=0.043).
Conclusion: Serum zinc levels were lower in patients with cutaneous warts than in healthy controls, but this difference was not statistically significant. Serum zinc level and duration of warts involvement were related. The duration of warts and serum levels were inversely correlated.

Abstract
Background: Alzheimer dementia as the most common cause of dementia is a chronic, progressive, irreversible and incurable disease. The second most common cause of dementia after Alzheimer is vascular dementia. One of the systems involved in dementia is the visuospatial system and visual evoked potential (VEP) can be one of the diagnostic methods for this disease. Therefore, the present study aims to compare visual evoked potential changes in Alzheimer dementia, vascular dementia and patients with minimally conscious impairment (MCI) with healthy people.
Methods: A case-control study was performed on referred clients to Shariati Hospital, Tehran, Iran, from April 2015 to September 2016. Patients with cognitive impairment went through Montreal cognitive assessment (MOCA) test and divided into three groups of Alzheimer dementia, vascular dementia and patients with minimally conscious impairment. Subjects with normal cognition were included in the control group. The visual evoked potential test was performed on all participants in two Methods: pattern shift visual evoked potential (Ps-VEP) and flash visual evoked potential (f-VEP) and results were compared between groups.
Results: Forty patients were studied in four groups (three patient groups and one control group). 70 percent in Alzheimer group and 60 percent in vascular dementia group had abnormal pattern shift visual evoked potential. Only in Alzheimer group visual evoked potential P100 latency was significantly higher than control group and in other groups, there was no significant difference. Also there was no significant difference between groups in the study of flash visual evoked potential variables including P1, N2, P2 and N3.
Conclusion: This study showed that only Alzheimer was associated with a significant increase in visual evoked potential P100 latency. On the other hand the other hand, there was no significant difference in flash visual evoked potential variables including P1, N2, P2 and N3 between different groups which shows that flash visual evoked potential cannot differentiate between Alzheimer dementia, vascular dementia, patients with minimally conscious impairment and normal people.

Abstract
Background: Atrophy of hippocampal subfields is one of the diagnostic biomarkers of Alzheimer's disease, which has also been observed in many patients with mild cognitive impairment. There is still no clear understanding of the atrophy pattern of hippocampal subfields in Alzheimer's disease and its differentiation from mild cognitive impairment. In this cross-sectional study, hippocampal subfield atrophy in Alzheimer's patients were compared with patients with early (EMCI) and late (LMCI) cognitive impairment and the control group.
Methods: This was a cross-sectional study conducted from September 2021 to September 2022 in the radiology department of Tabriz Paramedical Faculty. MRI images of Alzheimer's patients, EMCI patients, LMCI patients, and normal controls (NCs) were obtained from the ADNI database. Different hippocampus subfields of hippocampal fissure, dentate gyrus head, dentate gyrus body, first cornu ammonis body, cornu ammonis head, subiculum body, and subiculum head were isolated using the hippocampus segmentation tool in FreeSurfer 7.0 software. The volume of all subfields was calculated bilaterally and normalized. The volume difference of each hippocampus subfield between the groups participating in the study and the pair volume difference between the groups was analyzed using the Kruskal-Wallis H Test and post-hoc Dunn's test. The P<0.05 was considered as the significance level.
Results: The most significant volume difference between the four groups participating in the study was related to the whole hippocampus, DG body, subiculum body, and subiculum head subfields (P<0.0001). Also, when examining pairs, the most significant difference was observed between the NC/AD pair (P<0.0001) and the least significant difference between the pair of LMCI/AD group (P<0.05) and in the subfield subiculum body showing the progressive course of hippocampal subfield atrophy with cognitive progress towards Alzheimer's disease.
Conclusion: In most subfields of the hippocampus, a significant difference in atrophy can be seen, increasing the severity of atrophy as the disorder progresses toward Alzheimer's. Such findings can help guide future studies to improve diagnostic performance to identify individuals at high risk of Alzheimer's disease.

Investigating the reproducibility of radiomics features extracted from ultrasound images as diagnostic biomarkers in patients with hepatocellular carcinoma

Abstract
Background: Radiomics is a noninvasive method that reveals information from medical images that are not recognizable by the naked eye. Radiomics has shown a high potential in the accurate diagnosis and prognosis of liver lesions in ultrasound images. Despite this high potential, changes in imaging parameters affect the reproducibility of ultrasound radiomics results. Therefore, the present study aims to investigate the reproducibility of the radiomics features extracted from the images of patients with hepatocellular carcinoma under changes in ultrasound scan parameters.
Methods: This was a cross-sectional study conducted from July 2020 to July 2021 in the radiology department of Tabriz Paramedical Faculty. The images of 20 patients with hepatocellular carcinoma were obtained from the Cancer Imaging Archive database. These images were taken under different imaging conditions and parameters. The areas related to the lesion were manually extracted from the images with software tools. Then, in order to radiomics analysis, different radiomics features, including 24 gray level co-occurrence matrix (GLCM) and 16 gray level run length matrix (GLRLM), were extracted from the images. Then, using the coefficient of variation (CV%) and intraclass correlation coefficient (ICC) statistical tests, the reproducibility of radiomics features under changes in scan parameters was investigated. The values of ICC≥0.90 and CV<20% were considered reproducible in this study.
Results: Among the 40 features extracted from ultrasound images, eight showed high reproducibility in both CV% and ICC tests. These features were joint entropy, Idmn, Imc2, correlation, MCC, sum entropy, gray level non-uniformity normalized, and run entropy in which the two features, Idmn and gray level non-uniformity normalized, showed the highest (CV%=0.24) and the lowest (CV%=14.90) stability against the changes of ultrasound scan parameters, respectively. The average ICC value of these features was obtained at 0.977.
Conclusion: Despite the high potential of radiomics in diagnosing liver lesions, changes in imaging parameters directly affect the reproducibility of results. However, some radiomics features still show high stability and reproducibility under changes in imaging parameters.
