Volume 70, Issue 7 (10-2012)
Abstract

Background: There are conflicting reports about zinc, a trace element, in the pathogenesis of hypertension and other cardiovascular diseases. The aim of this study was to evaluate the role of zinc in high blood pressure.
Methods: We conducted this study on 80 patients with primary (idiopathic) hypertension and 80 normotensive people with similar age who attended to Tehran Heart Center between 2007 and 2008. We examined the effect of zinc concentration on blood pressure in both sexes in four age groups (41-50, 51-60, 61-70 and 71-80 years old). We measured plasma zinc concentration by atomic absorption.
Results: The mean plasma zinc concentrations were 0.456±0.04 µg/ml and 0.551±0.055 µg/ml in patients with hypertension and in normotensive people, respectively, (P≤0.05). Nevertheless, the mean plasma zinc concentrations were 0.494 µg/ml and 0.486 µg/ml in men with and without hypertension, respectively. The mean plasma zinc concentrations of women with and without hypertension, respectively were 0.415 µg/ml and 0.596 µg/ml, showing a significant difference between two groups (P≤0.001). Moreover, there was a significant difference in plasma zinc concentration between hypertensive and normotensive people in 51 to 60 years age group (P≤0.05), but difference were not significant between other age groups.
Conclusion: The results of this study revealed the relationship between the decrease in plasma zinc concentration and increase in blood pressure in women and in the men aged 51 to 60 years.

Volume 70, Issue 7 (10-2012)
Abstract

Background: Finding an acute brain lesion by diffusion-weighted (DW) MRI upon an episode of transient ischemic attack (TIA) is a predictor of imminent stroke in the near future. Therefore, exploring risk factors associated with lesions in DW-MRI of the brain is important in adopting an approach to TIA management. In the current study, we tried to determine the risk factors associated with lesions in DW-MRI of the brain in patients experiencing TIA episodes.
Methods: Fifty patients with TIA were recruited consecutively in Sina Hospital, Tehran, Iran, over a 6-month period between July 2008 and January 2009. All of the patients underwent a complete neurological examination and laboratory tests. Brain DW-MRIs were performed for all the patients within 72 hours of a TIA episode.
Results: DW-MRI revealed an acute lesion in 16% of the participants. There was a significant correlation between presence of an acute lesion in DW-MRI and TIA duration, history of diabetes mellitus and presence of unilateral facial palsy (P=0.0003, P=0.02 and P=0.008, respectively). Other variables such as age, hypertension, hyperlipidemia, past history of TIA, headache, vertigo, and sensory or visual disturbances had no significant relation with the presence of an acute lesion in DW-MRI.
Conclusion: Duration of TIA, presence of diabetes mellitus and unilateral facial palsy are risk factors for an acute lesion in DW-MRI, meaning that patients with such risk factors are at risk for stroke in the near future.

Volume 71, Issue 6 (9-2013)
Abstract
Background: Ischaemic pain counts among the most difficult to treat pains in palliative care. Ischemic pain is frequently severe, and usually resistant to available analgesics. Treatment of this condition is difficult, especially when the condition is inoperable.
Case presentation: A 36-year-old woman with the diagnosis of systemic lupus erythematosus with severe ischemic pain in the lower leg due to vascular problems presented to Akhtar Hospital. The patient was arranged for lumbar sympathetic block which was performed in two stages with one week interval. In the procedure, a long needle with No. 22 gauge and the length of 15 cm was used. Under view of fluoroscopy guide, 10 cc marcaine 0.125% was injected. In the second stage, 5 cc of marcaine 0.25% and 5 cc of phenol 0.6% were used. Pain improvement was observed immediately after neurolytic lumbar sympathetic block. Three-month follow up period revealed improvement of quality of life.
Conclusion: Lumbar sympathetic block is considered as a safe and useful technique. Clinically, the technique is effective for pain relief in patients who develop lower leg pain due to vasculitis.

Volume 72, Issue 12 (3-2015)
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.

Abstract

Background: Cardiopulmonary resuscitation, commonly well-known as CPR, is an emergency technique that includes chest compression often with artificial ventilation in an exertion to manually preserve complete brain task until additional measures are taken to return spontaneous blood circulation and breathing in a person who is in cardiac arrest. According to the International Liaison Committee on Resuscitation Guidelines, CPR includes chest compressions for adults between 5 cm (2.0 in) and 6 cm (2.4 in) deep and at a rate of at least 100 to 120 per minute. Cardiopulmonary resuscitation is aimed to reverse vital organs as like as heart, lungs and for subsistence of patients. Several researches showed that different factors affect the resuscitation results. The current study was designed to assess the results of resuscitation and its association factors.

Methods: This retrospective, descriptive and analytic study was carried out in Baharloo Hospital, Tehran, Iran during March 2014 and February 2015. In current work, all resuscitated patients were imported and patients with uncompleted files and died before entrance to hospital were excluded. The data was obtained from medical records units, office files unit and the unit of quality improvement. Data were analyzed by use of SPSS version 22 (Armonk, NY, USA) software and Chi-square test and Student’s t-test.

Results: From 891 patients, 813 cases were entered the study that 498 (61.3%) were male and 315 (38.7%) were female. 41.1% of resuscitation were successful and 58/9% were unsuccessful. The mean and standard deviation time of resuscitation was 28.80 and 12.6 minutes; the most frequent primary diagnosis was cardiovascular disease. In this study there was a significant difference between age and duration of the resuscitation with successful resuscitation (P= 0.02) but, in the variables of ward and resuscitation team were not significant (P> 0.05).

Conclusion: The results of this study showed that resuscitation in younger group, short duration of resuscitation and patients without heart diseases are more successful.

Soheila Aminimoghaddam, Saeedehsadat Batayee , Mahsa Velaei ,
Volume 75, Issue 5 (8-2017)
Abstract
Background: About 90% ovarian cancers are epithelial and 10-15% of this group are mucinous. The treatment is the hysterectomy with bilateral salpingo-oophorectomy.  However, most of these tumors occur in young women that have not yet given birth in which preservation of fertility should be considered. We present a case of huge mucinous cystadenoma and massive ascites managed by preserving uterus and ovaries. Meigs’ syndrome is found in fibroma, and thecoma of ovary, however, in rare occasion this syndrome is occurred in mucinous cystadenoma.
Case presentation: A 21-year-old unmarried woman presented with the complaint about weight gains and irregular menstruation for four months to gynecology clinic of Firoozgar hospital in Tehran in October 2016. Preop lab data including tumor marker was gathered, and sonography with CT scanning of pelvic and chest was performed. The ascitic fluid was negative for malignancy. Also, laparotomy with staging the ovarian tumors was carried out including cytology of ascitic-fluid, cytology of diaphragm, ovarian cystectomy, biopsy of the paracolic gutter, exploring abdomen and pelvis. Histopathology report revealed mucinous cystadenoma. Moreover, according to the normal appearance of the appendix in this case, the appendectomy was not performed.
Conclusion: Ovarian cysts in young women who are associated with elevated levels of tumor markers and ascites require careful evaluation. Management of ovarian cysts depends on patient's age, size of the cyst, and its histopathological nature. Conservative surgery such as ovarian cystectomy or salpingo-oophorectomy is adequate in mucinous tumors of ovary. Multiple frozen sections are very important to know the malignant variation of this tumor and helps accurate patient management. Surgical expertise is required to prevent complications in huge tumors has distorted the anatomy, so gynecologic oncologist plays a prominent role in management. In this case, beside of the huge tumor and massive ascites uterine and ovaries were preserved by gynecologist oncologist and patient is well up to now.

Volume 76, Issue 3 (6-2018)
Abstract
Background: Tenderness, pain, muscle weakness, and limited range of motion (ROM) are symptoms of myofascial pain syndrome, which leads to restrictions on physical, occupational and social activities and ultimately reduction of productivity and quality of life. Different methods of rehabilitation are used to improve the symptoms of these patients. One of the new methods is the use of kinesio tape. The aim of this study was to evaluate the effect of kinesio tape on neck pain and disability and also muscle strength in myofascial pain syndrome.
Methods: In this single-blind randomized clinical trial, from June to November 2017 in Imam Hossein Hospital of Mashhad, Iran, thirty individuals (male and female) with Myofascial pain syndrome were divided into two groups (treatment and control), randomly by lottery. In treatment group, the kinesio tape with appropriate tension was applied directly over pain place and on upper trapezius muscle; and control group received placebo kinesio tape (kinesio taping without tension). In this study, before and three days after application of kinesio taping, numerical pain rating scale (NPRS), neck disability index (NDI) and manual muscle testing (MMT) were used to assess pain, disability and strength, respectively.
Results: To compare the effect of treatment, the mean of variables were compared with independent sample t-test before and after treatment. Pain and strength of upper trapezius were significantly different in both groups (P< 0.05), but in neck disability there was not significantly difference (P< 0.05). Then, for a closer examination, the paired t-test were used to compare the mean of disability before and after the treatment and result showed a significantly different in the treatment group and was not significantly different in the control group.
Conclusion: According to the results of this study, kinesio tape can reduce neck pain, increase the strength of upper trapezius, and ultimately reduce the disability of neck in myofascial pain syndrome. Therefore, this method can be used in rehabilitation clinics to improve the symptoms of patients with myofascial pain syndrome.

Abstract
Background: Ovarian fibroma is the most common benign solid tumor of the ovary. The most common symptoms are abdominal discomfort and pain. Ovarian fibroids are associated with Meigs syndrome in 1% to 10% of cases. The aim of study is report of a case of Meigs syndrome
Case presentation: A 65-year-old menopausal woman who complained of abdominal pain was referred to our academic hospital of Mashhad, Iran, in April 2018. In abdominal examination, a soft mass with size of 200×100 mm, was detected. Also leukocytosis and increase in CRP was observed. Marker CA125 was higher than 200. In CT scan in right adnexa heterogeneous mass 170×100 mm with enhancement was reveled. pleural effusion was reported in the both lungs and collapse of underlying lung tissue in Chest X-ray. Explorative laparotomy was performed. Ascites and inflamed omentum covered the surface of right ovary was detected. The huge solid-cystic hemorrhagic, irregular mass with a specific pedicle that enclosed in the capsule in right adnexa was seen. Right salpingo-oophorectomy was performed. The result of final pathologic was benign proliferative lesions of mitotic fibroblasts were reported according to ovarian fibroma.
Conclusion: In case of accompanying ovarian mass with ascites and pleural effusion, after the exclude of ovarian malignancies, Meigs syndrome should be considered in differential diagnosis.

Abstract
Background: Sesame oil can be used to treat cardiovascular diseases, such as atherosclerosis, by reducing the levels of fibrinogen and factor VII. The aim of this study is to prepare a microemulsion containing sesame oil as a drug nanocarrier for improving the aqueous solubility and therapeutic effects of this vegetable oil on the reduction of the fibrinogen and factor VII levels in animal model.
Methods: This experimental study was performed for microemulsion preparation and animal test at Ferdowsi University of Mashhad and Cardiovascular Research Center of Mashhad University of Medical Sciences, Mashhad, Iran, respectively, from April 2015 to January 2017. To prepare the microemulsion samples, Tween 80 and span 80 were selected as surfactant couple and surfactant ratios of 8:1, 9:1 and 10:1 were determined for construction of pseudo-ternary phase diagrams. The Zealand white rabbits were categorized in three groups: receiver of base diet group, high cholesterol diet and high cholesterol diet plus microemulsion.
Results: The average particle size of the samples was in the range of 16.64±0.1 to 21.16±0.2 nm with a uniform particle size distribution. Zeta potential was in the range of -10.7 to 18.4 mV, refraction index was approximately 1.39. Electrical conductivity coefficient was in the range of 297 to 311 μz and pH of all the samples were approximately 6.42 for all samples. All of the microemulsion samples were physically stable and the prepared sample with 9:1 surfactant ratio was selected to investigate the animal test due to the higher oil percentage in comparison with the other samples that be stable over 6 months. Significant decrease in the levels of fibrinogen and factor VII in the third group of rabbits was observed compared to the other groups.
Conclusion: The results of this study showed the effective performance of nanostructured drug delivery systems in the form of microemulsion to improve the aqueous solubility and therapeutic effects of hydrophobic compounds such as vegetable oils.

Reza Abdollahi , Bahman Vahidi , Mohammad Karimi ,
Volume 77, Issue 9 (12-2019)
Abstract
Background: Cerebral aneurysm disease causes intracranial hemorrhage by rupturing, which can eventually, lead to organ failure or death. For this reason, it is important to anticipate the reasons for rupturing of a cerebral aneurysm from biomechanical point of view. Investigating this disease may even help the physicians to find treatments and predict the patient’s situation. This research was conducted to understand risks of development and rupture of a patient-specific cerebral aneurysm.
Methods: In a computational simulation, fluid-structure interaction method has been used for a patient-specific case. Also, considering the speed of the systole as the initial condition of the problem, the blood fluid domain has been solved in three types of fluid mathematical models (Newtonian, non-Newtonian Carreau, and non-Newtonian power-law). Then, the pressure results on the wall have been transmitted to ANSYS software, version 15.0 (ANSYS Inc., Canonsburg, PA, USA) and the structure has been solved based on three material models (linear elastic, hyperplastic Neo-Hookean and hyperplastic Mooney-Rivlin, with 5 parameters). The study was done in University of Tehran, Iran, from October 2016 to September 2018.
Results: Shear stress, pressure, flow velocity, wall displacement and von-Mises stress have been extracted from the simulations. The average wall displacement of the aneurysm was 1.8 mm. Also, no significant difference was found in the amount of arterial wall displacement, with constant wall material model and different blood models. However, a significant difference has been observed in the case of considering constant blood model and different wall material models in the value of displacement.
Conclusion: With regard to the amount of displacement of the aneurysm wall in this particular patient, with the geometry and location of the specific aneurysm, the brain nerves 3 and 6 were under stress and exposed to damage. The minimum shear stress was in the aneurysm neck, which stimulates the endothelial cells in the area of aneurysm. In addition, the blood model didn’t had a significant effect on the displacement calculations, while the wall material model played a more decisive role.

Volume 77, Issue 11 (2-2020)
Abstract
Background: Hypereosinophilic syndrome is commonly found in various diseases such as allergic diseases, parasitic diseases, malignancies, etc. Fasciolosis may present with different clinical features, and it can make a difficult diagnosis of the disease. Laboratory manifestations of fascioliasis are eosinophilia. The purpose of this report was to introduce a child with hypereosinophilia that her diagnosis was fascioliasis.
Case Presentation: The patient was a 3-year-old girl who was referred for prolonged fever (more than two weeks) and abdominal pain from another medical center, and she was hospitalized. In abdominal and pelvic ultrasound, splenomegaly was seen and in laboratory tests, she had hypereosinophilia. In the flow cytometry of bone marrow aspiration, the only finding was increased eosinophil level. Abdominal and thoracic a computerized tomography (CT) scans showed an increased size of para-aortic lymph nodes. On her examination, lymphadenopathy was present in the inguinal region. Therefore, a biopsy of an inguinal lymph node was performed to rule out lymphoma. Lymph node biopsy was negative for lymphoma. Fasciola serology was performed for the patient, and the stool exam was collected three times (for one day in between) to rule out parasitic disease, including Fasciola, etc. Due to weakly positive serology Fasciola hepatica, triclabendazole was started for the patient (it was given in two doses, 12 hours apart), despite the absence of Fasciola parasitic eggs in her stool. During hospitalization, the patient’s fever was stopped and by starting the use of mentioned drug, eosinophilia was reduced. The patient received a complete improvement in the follow-up.
Conclusion: In patients with hypereosinophilia, parasitic diseases such as fascioliasis should be considered even if the fecal specimen is negative for Fasciola eggs.

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.

Volume 78, Issue 6 (9-2020)
Abstract
Background: Chronic kidney disease is considered as one of the most common health problems in the world. High mortality and morbidity in these patients, are due to cardiovascular disease and infections. Neutrophil to lymphocyte ratio is recently known as an inflammatory marker. This study aimed to determine the ratio of neutrophil to lymphocyte count in hemodialysis patients in Birjand Special Disease Center, and its role in mortality and morbidity during one-year follow-up.
Methods: This is an analytical descriptive study that was performed on 59 End-Stage Renal disease patients referred to the dialysis department of Special Disease Center, Birjand University of Medical Sciences Birjand, Iran. The levels of neutrophil to lymphocyte ratio, erythrocyte sedimentation rate, and C reactive protein were measured and cases divided into 4 groups according to the NLR: less than 1, 1-1.5, 1.5-2.5, 2.5-3.5, and>3.5. All patients were followed up for one year to determine rate of mortality, cardiovascular and infectious events.
Results: The mean NLR was 2.89±1.38. There was no significant difference in mortality rate between groups according to NLR with P=0.052, also no remarkable difference in infectious and cardiovascular morbidity events in groups with P=0.09 and P=0.21, respectively. The mean NLR in patients with cardiovascular or infectious events was 4.2 and 3.75 respectively, which were notably higher than patients without cardiovascular (NLR:2.49) and infectious (NLR:2.68) events, P=0.02 and P=0.03 respectively. In the bivariate correlation analysis, NLR was positively correlated with CRP in hemodialysis patients.
Conclusion: ESRD patients with NLR>2.5 have higher cardiovascular and infectious events than patients with NLR<2.5 but there was no difference in mortality rate between them.

Volume 79, Issue 2 (5-2021)
Abstract
Background: Chest pain is the most common reason for patients to be referred to the emergency department of hospitals. This study was performed to compare the GRACE and TIMI scores in predicting important cardiovascular events in patients.
Methods: This descriptive-analytical study was performed on 862 cardiac patients who were referred to the emergency department of Taleghani Hospital in Urmia in the period of April 1, 2016 to the end of September 2016 by census method. A checklist containing demographic information, medical history and risk factors was used to collect data. After scoring patients, we examined and followed up both groups over the next 30 days and recorded any cardiovascular events such as sudden death, AMI or immediate revascularization. The data were tested using SPSS16 and descriptive statistics tests. T-test and ROC curve were analyzed.
Results: The results showed that in general, out of 862 patients who were studied (50.3%), 433 were female and (49.7%) 429 were male. Most of the patients were under 65 years old 627 (72.7%) and the age range was (17-91). The highest initial diagnosis of nonSTEMI patients was UA with 811 (94.9%) cases. On the other hand, the highest risk factors of patients were HTN 449(52%), CAD 314 (36.425) and DM 22 (25.55). The highest blood pressure was between (100-120) with 328 cases and serum creatinine between (0.6 to 1.3) with 770 cases. MACE after 30 days in GRACE system 17 people (32.69%) were in high risk group and in TIMI 3 people (37.5%) were in high risk group. In MACE evaluation, the specificity of GRACE system (cutoff point=30) was 89.27 vs. 52.24, the specificity of TIMI system (cutoff point=7.3) and the sensitivity of GRACE 93 (cutoff point=10) versus TIMI 85.71 (cutoff point=8.3) is.
Conclusion: The results showed that GRACE was more sensitive and characteristic than TIMI.

Ahmadreza Assareh, Maryam Jozaei, Hoda Mombeini , Nehzat Akiash ,
Volume 79, Issue 10 (1-2022)
Abstract
Background: In patients with ST-segment elevation myocardial infarction (STEMI), Primary percutaneous coronary intervention (PCI) is the preferred reperfusion therapy. Timely primary PCI is essential in improving the clinical outcomes of these patients. The aim of this study was to evaluate the factors affecting balloon delay in STEMI treated patients by primary PCI and its relationship with major adverse cardiac events (MACE).
Methods: This prospective observational study was conducted on 143 cases of STEMI patients, who had the inclusion criteria and were treated by primary PCI, after obtaining written consent in Imam Khomeini hospital in Ahvaz, between May 2019 to May 2020. All-time components from symptom onset to PCI treatment include symptom-to-balloon time or ischemic time, symptom-to-door time and door-to-balloon time calculated. The incidence of major adverse cardiovascular events (MACE) including decompensated heart failure (DHF), acute coronary syndrome (ACS), sudden cardiac death (SCD) and cerebrovascular accident (CVA) was evaluated during 12 months follow up after primary PCI. left ventricular ejection fraction (LVEF) changes were evaluated 3 months after primary PCI.
Results: The median symptom-to-door time was 200.5 minutes (IQR: 90-438.75 min), the median ischemic time was 406 minutes (IQR: 231-671 min), and most patients had an ischemic time ≥120 minutes (92.4%) and door-to-device time ≥90 minutes (64.3%). The most common delay for treatment was in the symptom-to-door time (76.9%) and then the decision for primary PCI to transfer to the cat lab (17.5%). Overall, 59 (41.3%) of the patients experienced MACE during 1-year of follow-up, including ACS (13.3%), DHF (22.4%), cardiac death (9.8%) and CVA (2.1%). The patients age (OR: 0.96, P=0.020), LVEF changes (OR: 1.123, P=0.005) and STEMI type (OR: 0.705; P=0.039) predicted in-hospital MACE, while the symptom-to-balloon time (P=0.607) and door-to-balloon time (P=0.347) were not associated with MACE.
Conclusion: None of the time intervals were associated with the occurrence of MACE in one-year follow-up, and most STEMI patients were admitted to the hospital with a long delay. Therefore, efforts to shorten the time of hospitalization admission can help improve the MACE in STEMI patients under primary PCI in our medical centers.

Volume 81, Issue 4 (7-2023)
Abstract
Background: Vasculitis is a heterogeneous group of diseases that means an inflammatory process in blood vessels. Diagnosing vasculitis in children is challenging due to the variety of symptoms. Classification of childhood vasculitis is usually based on clinical phenotypes, size of affected vessels (small, medium, or large), and pathology of inflammatory infiltrates. The aim of this study is to investigate the epidemiological information on types of vasculitis and their clinical symptoms in children in eastern Iran.
Methods: This 3-year descriptive cross-sectional study was performed on all male and female patients with any vasculitis referred to the outpatient clinic and rheumatology department of Akbar Children's Hospital from the beginning of September 2017 to the end of September 2020. Has been. This study was based on information obtained from the checklist (information from the inpatient and outpatient records and information in the HIS). Checklist information included age, gender, drug history, history of surgery, clinical symptoms in different systems, season of disease onset, etc.
Results: Out of 263 children, 135 (51.33%) had Henoch-Schonlein and 100 (38/02%) of them had Kawasaki. The numbers of Behcet, Takayasu and Churg-Strauss patients were 20, three and two, respectively. In most subgroups, female patients were more common than male patients. Kawasaki and Takayasu had the lowest and highest age of onset, respectively. The most common seasons of appearance for Henoch-Schonlein and Kawasaki were autumn and summer respectively. In most subgroups, skin rashes are the most common clinical symptom, with, the most common types being petechiae and purpura.
Conclusion: In the present study, the most common type of vasculitis diagnosed in children in eastern Iran was reported by Henoch-Schonlein and Kawasaki respectively, which was completely different from the most common types of vasculitis in adulthood and indicated the importance of age in diagnosing the type of vasculitis. The necessity of clinical suspicion of these two diseases in children with skin rashes, along with matching with other clinical findings, is undeniable.

Abstract
Congenital cataract refers to the presence of any opacity in the lens at birth or during early childhood. Cataracts in children can manifest as unilateral or bilateral, congenital or acquired, with specific inheritance patterns or occurring sporadically. Additionally, the condition can be stable or progressive. Congenital cataracts can be associated with certain systemic diseases, or they may occur in the eye of an otherwise healthy child in isolation. Congenital cataract is one of the main causes of blindness in childhood. According to the report of the World Health Organization in 2001, congenital cataract is responsible for about 5 to 20 percent of cases of childhood blindness in the world based on different geographical regions. Untreated cataract in children leads to a tremendous social, economic and emotional burden for the child, family and society. Common complaints associated with congenital cataracts often include leukocoria (white pupil), reduced vision, a child's inability to track objects up close, light sensitivity leading to eye closure, squinting, the presence of either small eyes (microphthalmos) or large eyes (buphthalmos), strabismus (eye deviation), and abnormal eye movements such as nystagmus. Childhood cataract-related blindness can be cured with early detection and appropriate management. Managing pediatric cataracts is a challenge. Increased intraoperative complications compared to adults, tendency to increase postoperative inflammation, associated with complications such as aphakic glaucoma and persistent fetal vasculature, change in refractive status of the eye, and tendency to develop amblyopia, all complicate the achievement of good vision. Congenital cataract has a good prognosis if it is diagnosed early and surgery is performed before 6 weeks. Factors that may adversely affect the outcome, include the presence of unilateral cataract, presence of nystagmus, strabismus, or any ocular defect such as microphthalmos and PFV. Pediatric cataract surgery has evolved over the years, and with improved knowledge about myopic shift and axial growth, outcomes for these patients have become more predictable. Optimal results depend not only on effective surgery, but also on careful postoperative care and visual rehabilitation. Hence, it is the combined effort of parents, surgeons, anesthesiologists, pediatricians and optometrists that can make the difference.

Effect of resistance training modalities on angiogenic indices in sedentary male students

Volume 81, Issue 6 (9-2023)
Abstract
Background: Angiogenesis is a physiological process leading to capillary density enhancement and better blood distribution in skeletal muscles, which triggers in response to physical training. The present study aimed to investigate the changes in physiological factors involved in angiogenesis in response to circuit or traditional resistance training.
Methods: Thirty-six healthy sedentary students who were studying at Shahid Rajaee Teacher Training University of Tehran (age: 22.1±2.3 years; height: 172.7±5.1 cm) volunteered to participate in the study (from October 2021 to February 2022). Following a pre-test to evaluate one repetition maximum (1RM) of selected movements (Leg Press, Leg Curl, Leg Extension, Bench Pull, Seated Row, Biceps Curl), subjects randomly divided into Circuit Resistance training (CRT) (training protocol included 4 circles/3 times a week/8 weeks circuit performance/50-55% 1 Repetition Maximum (1RM), n=12), Traditional resistance training (RT) (training protocol included 8 repetition/3 set/3 time per week/8 weeks of same movements with 75% 1RM followed by 2 minutes break to rest between the sets; n=12) and the control group without any regular training (n=12). We assessed the level of Vascular Endothelial Growth Factor (VEGF), plasma level of growth hormone (GH), and Basic Fibroblast Growth Factor (BFGF) to the mentioned training methods. Data were evaluated by utilizing SPSS version 14.
Results: Present findings showed that CRT and RT protocols resulted in significant increases in post-test compared to pre-test in VEGF (P=0.00), GH (P=0.04), and BFGF (P=0.00). In addition, the magnitude of changes in VEGF and GH were significantly greater than the magnitude of changes in control group in post-test (P=0.03, and 0.001, respectively). Furthermore, there was a strong correlation between absolute values of GH and VEGF (r=0.74 and r=0.71) following CRT (P=0.01) and RT (P=0.02).
Conclusion: This study demonstrated that CRT and RT might enhance angiogenesis through an increase in VEGF, bFGF and GH, leading to better blood distribution in muscles.

Abstract
Background: Vascular traumas are among the important traumas, most of which lead to significant complications due to the lack of correct and timely diagnosis, considering the frequency of penetrating vascular injuries, especially in our country and Khuzestan province, as well as the complications and mortality caused by injuries. This study was designed to investigate the effect of vascular surgery intervention on patients with arterial injury of forearm trauma.
Methods: In this descriptive-analytical study, all trauma patients suspected of penetrating forearm arterial injuries in terms of age, sex, type of trauma, location of trauma, type of intervention, location of arterial repair, angiographic and clinical findings including damaged arteries, type of injury Arterial fracture or dislocation. The proximity of vascular damage and the complications of surgical interventions are investigated.
Results: The results of this study showed that among the penetrating trauma patients requiring surgical intervention, 90.4% were men and only 6.9% were women. The average age of the patients was 32 years. The most frequent trauma requiring surgical intervention in this study was primary repair of a stab wound in the ulnar artery and the least was due to explosive. According to the obtained results, there was a statistically significant relationship between the amount of bleeding, the days of hospitalization and the duration of the operation with the type of trauma. The most damaged artery was ulnar artery 7.50% and the most type of arterial damage was arterial cut with active bleeding (7.39%).
Conclusion: According to the results of the present study, the most damage was in the ulnar artery caused by trauma with sharp objects (knives). The incidence of complications in primary repair surgery was higher than other types of surgical interventions, and there was a statistically significant relationship between the amount of bleeding, days of hospitalization, and duration of surgery with the type of trauma.
