Abstract
Background: The amount of anterior tibial translation during rehabilitation exercises is a key factor in organizing exercise regimen after anterior cruciate ligament injury. Excessive anterior tibial translation could increase the magnitude of tension imposed on injured and reconstructed anterior cruciate ligament knees. Forward lunge and open-kinetic knee extension exercises are commonly used in anterior cruciate ligament rehabilitation. However, there is insufficient data about the amount of anterior tibial translation in the eccentric and concentric phases of these exercises. This study compared the amount of anterior tibial translation in the eccentric and concentric phase of the lunge and seated knee extension in anterior cruciate ligament deficient and intact knees.
Methods: Using a non-probability sampling method, 14 men with unilateral anterior cruciate ligament rupture were selected for participation in this cross-sectional study. Participants were recruited from the university’s physiotherapy clinics. A uni-plane fluoroscope was used to image the knee joint while participants performed the forward lunge and open-kinetic knee extension exercises with the intact and injured legs in random order. Fluoroscopy imaging was performed in the radiology center at Sina Hospital, Tehran, Iran, from September 2013 to February 2014. Two factorial mixed ANOVA was used to analyze the data.
Results: There were no significant differences in the anterior tibial translation between the limbs and contraction phases during the lunge exercise. During open-kinetic knee extension, the anterior tibial translation in anterior cruciate ligament deficient knees was significantly more than that of healthy knees at 0⁰ (P=0.007). The anterior tibial translation in the eccentric phase of open-kinetic knee extension at flexion angles of 0⁰ (P=0.049) and 15⁰ (P=0.024) was significantly greater than that in the concentric phase.
Conclusion: In the lunge exercise, the amount of anterior tibial translation was similar between the eccentric and concentric phases and the intact and anterior cruciate ligament deficient knees, however, during open-kinetic knee extension exercise, in the eccentric phase was greater than that in concentric, and in the intact knees was greater than that in the intact knees, at 0-15⁰ angles.

Abstract
Background: Long QT syndrome (LQTS) is a disorder in which electrical cardiac ventricular repolarization is impaired. It results in an increased risk of an irregular heartbeat which can result in palpitations, fainting, drowning, or sudden death. Long QT Syndrome may present as tonic-clonic seizure or a seizure-like disorder. By taking a superficial electrocardiogram (ECG) and proper diagnosis, Sudden death, one of the most important complications of Long QT syndrome can be easily prevented.
Methods: This is a prospective case-control study that was conducted in the emergency department of Taleghani Children's Hospital of Gorgan University during 2017.
Four hundred and eighty subjects in three groups (two cases and one control groups), were included in this study. These comprised as patients with afebrile convulsion (n: 160), patients with seizures associated with fever (n: 160), and the control group (patients who have been hospitalized for any reason other than seizure (n: 160)). Those with severe cerebral palsy, acute meningitis, prolonged loss of consciousness, severe disturbances of electrolytes and those who were taking drugs that affect the QT interval were excluded. Once admitted with a primary diagnosis of seizure, a 12 leads superficial ECG was performed.
Results:  In the group of patients with febrile convulsion, 123 children were Low probability Long QT syndrome, 33 cases were Intermediate and 4 were high probability Long QT syndrome. Probability of Long QT syndrome in children with afebrile seizures showed that 112 children were in Low probability Long QT syndrome, 42 children in Intermediate and 6 children in High probability Long QT syndrome group. Comparison of Probability of Long QT syndrome among the three evaluated groups showed that children with afebrile seizure (48 children) and subsequently children with febrile seizure (37 children) were more in Intermediate and High categories than others. Only 11 children in the control group were in the Intermediate and High groups. Chi-square test results showed a significant difference with P<0.001.
Conclusion:  The results of this study show that in patients who present with seizure as the initial symptom, it is always mandatory to account Long QT syndrome into differential diagnosis. Doing a simple electrocardiogram makes it easy to distinguish two issues and prevent sudden death.

Volume 79, Issue 7 (October 2021)
Abstract
Background: Spinal anesthesia is a type of neuraxial anesthesia that brings ample benefits. However, due to the fear of this type of anesthesia, many pregnant people refuse to experience it. In this study, we aimed to investigate the levels and causes of fear of spinal anesthesia in candidates for cesarean section.
Methods: The current study is a cross-sctional study performed on 67 patients undergoing cesarean section who were referred to the operation room of Shariati Hospital, in Tehran from September 2018 to September 2019. Matthey questionnaire, which consisted of three sections (demographic information, history of spinal anesthesia and fear of anesthesia), was filled out by candidates and after collecting information, the data were analyzed by SPSS software.
Results: Pain over the surgery showed a significant relationship with the history of spinal anesthesia in 4 pregnant women (12.9%) and in 25 women (65.8%) without a history of anesthesia (P<0.0001). In addition, the fear of being awake and looking at the cesarean section during surgery was significant in 7 patients (22.6%) with a history of spinal anesthesia and 18 patients (47.4%) without a history of disease (P<0.0001). Fear of anesthesia needle was also significantly observed in 7 patients (23.3%) with a history of spinal anesthesia and 23 patients (60.5%) with no history of spinal anesthesia (P<0.0001). Fear of back injury was seen in 9 candidates (29%) of patients with a history of spinal anesthesia and in 23 patients (60.5%) of patients without a history of anesthesia (P<0.033). The results of our study also showed a significant relationship between the history of general anesthesia and fear of nausea and vomiting (P<0.046) as well as fear of anesthesia needles (P<0.001).
Conclusion: Patients with a history of spinal anesthesia were significantly less afraid of feeling pain during surgery, seeing surgery, spinal anesthesia needles, and spinal impairments. Moreover, patients with a history of general anesthesia were significantly more afraid of spinal anesthesia, nausea and vomiting than others.

Abstract
Background: Determining the rank of important parameters in ranking health care and providing health services to patients in medical centers.
Methods: The research method is descriptive-analytical and applied in terms of classification. The data is from the database of the Faculty of Health and Medicine of the University of Tehran, which was collected as an archive from April 1998 to May 1999. The statistical population were all experts, specialists and experts of the Faculty of Health 29 of whom completed the questionnaire. The weight of the criteria was evaluated using the AHP method and in the next stage, the medical centers were ranked using the DS-VIKOR method. The analysis method in this study consists of the following steps steps:
• Implementing a simple VIKOR method.
• Implementing the Dempster-Shafer and Vicker method.
• Implementing the AHP method
• Implementation of the Topsis method.
• Comparing the proposed methods to review and compare which ones work best.
Results: The weight of medical centers was assessed by AHP method and then the combined centers were ranked by Dempster-Shafer and VIKOR combined methods  using the information of four medical centers, the DS-Vikor approach was implemented. The purpose of six criteria and three experts was used for evaluation. The results show that the effectiveness of care and treatment process is more important from the experts' point of view. Dempester-Schaefer and Vicor The medical centers in question are ranked. For validation, at the end, the medical centers were ranked by TOPSIS method.
The integrated system includes various subsystems giving caring and providing health services to patients in medical centers that can be built and configured and are ranked.
The model can investigate the effectiveness of giving caring and providing health services to patients in medical centers.
Conclusion: By combining the two methods of Dempster-Shafer and Vicker, the confidence in the whole uncertainty is improved and the results are more reliable. This approach can help reduce the uncertainty caused by people's cognition to increase the level of decision-making, allowing us to overcome the problem of choosing the right level of uncertainty and to deal with uncertainty in a practical and justified way.

Abstract
Background: Obesity and overweight are one of the components of metabolic syndrome and the cause of cardiovascular disease and sudden cardiac death. Obesity is associated with a wide range of electrocardiogram (ECG) abnormalities.
Methods: This case-control study was performed on 50 children and adolescents aged 9 to 18 years in Birjand from May to October 2020. In the control group, 25 people with normal weight and in the case group, 25 people with obesity or overweight were included in the study. Individuals with a body mass index of 85-95 percent were defined as overweight, ones with a body mass index above the 95th percentile were defined as obese, and individuals with a body mass index below the 85th percentile were defined as normal. After clinical examination, height, weight and electrocardiogram indices were measured and compared by using statistical tests by SPSS (Version 19) software.
Results: There were 15 boys in the control group and 17 boys in the case group. The mean age of the control and case groups was 11.28±2.13 and 10.96±1.97 years, respectively. The mean distance between the peak to the end of the T wave in the case group was 323.72±120.15 and in the control group was 79.20±13.06. The mean difference between the shortest and longest distance of TP-e in case group was 48±23.04 and in control group was 18.44±5.58, respectively. There was a statistically significant difference between the two indices (P<0.001). But in other variables, no statistically significant difference was observed between the two groups.
Conclusion: The results of the present study showed that obesity can have adverse effects on the ECG of children compared to normal-weight individuals. These changes are associated with an increased risk of arrhythmias. Given that these changes can be corrected with weight control, it is recommended to warn families and educate them to prevent and control overweight and obesity.

Primary pyogenic spinal infection: a review article

Abstract
Primary pyogenic spinal infection, also known as spondylodiscitis or vertebral osteomyelitis, is a serious and potentially debilitating condition involving a bacterial or fungal infection of the intervertebral disc space and adjacent vertebral bodies. While relatively uncommon, with an estimated incidence of 2.4 per 100,000 population per year, it is a medical emergency that requires prompt diagnosis and treatment to prevent permanent spinal damage and neurological complications. The most common causative organisms are Staphylococcus aureus, which accounts for up to 50% of cases, followed by Gram-negative bacteria such as Escherichia coli, and mycobacterial infections like Mycobacterium tuberculosis. Risk factors for developing primary pyogenic spinal infection include intravenous drug use, a weakened immune system, recent spinal surgery or instrumentation, and contiguous spread from an infection elsewhere in the body, such as a urinary tract infection or endocarditis. Patients typically present with severe, localized back pain, fever, and general malaise, which can easily be mistaken for more common spinal conditions. Prompt diagnosis is critical and involves a thorough medical history, physical examination, laboratory testing, and advanced imaging studies such as magnetic resonance imaging (MRI). Blood cultures and, in some cases, image-guided biopsy may be necessary to identify the causative organism and guide appropriate antimicrobial therapy. The mainstay of treatment is the prompt initiation of targeted antibiotic or antifungal therapy, often requiring intravenous administration for several weeks. Surgical intervention may be necessary in some cases, such as to drain an abscess or provide spinal stabilization. A multidisciplinary approach involving infectious disease specialists, spine surgeons, and rehabilitation providers is essential for optimal management and outcomes. Despite advances in diagnosis and treatment, primary pyogenic spinal infection remains a challenging condition. Delays in diagnosis and treatment can lead to devastating complications, including permanent spinal deformity, paralysis, and even death. With timely and appropriate management, however, most patients are able to achieve a good clinical outcome, though some may experience residual pain or neurological deficits.
