Background & Objective: Burning is a general health problem and is also a global injury as well as a very serious sanitary issue in industrial and developing countries. In its severe form, burning can claim lives. It seems essential in every society to analyze burning, to study the causes of burning, treatment outcomes and the death rates, etc. to find proper preventive measures. Materials & Methods: In this cross-sectional study, the medical records of all patients who were hospitalized and finally deceased during the years 2002 and 2004 in Zare' teaching hospital, Sari, were examined. Some variables including the age span average, the degree and percentage of burning, patients' residence, gender, the cause of burning (i.e. boiling water, fire, acids and explosives), average hospitalization period, surgery and also the abundance of self – burning attempts were examined. Results: This study indicate that during these 3 years the total number of those who died from burns was 506 (23.4%). The residential places were in Mazanderan province (41.7%), Golestan province (41.4%), and Gilan province (10.2%). The abundance of burning ranges as below: The 2 and 3 degree of burning at 91.8%. Regarding the percentage of burns, 31.7% of abundance pertains to burning at 90% and more. The greatest external causes leading to burns are petrol, gas, and gas oil at 57.9%. Also, the percentage of burns does not have much influence on death rate among 50 – year – olds and older people. Conclusion: This study indicated that the importance of death between burned patient in special sex and age. To establish hospitals, some issues must be considered as: distance, transportation, route dangers, characteristics of area, existing epidemiological survey, and finally the epidemics and event statistics.

Background and Objective: Ankle instability is one of the most prevalent injuries among athletes. Biomechanical changes, sensory-motor impairments, and neuromuscular disorders have been reported in individuals with chronic ankle instability. The present study was conducted to compare the electrical activity of selected leg and thigh muscles during performing functional movements in female athletes with and without chronic ankle instability.
Methods: This case-control research was conducted on 40 female athletes in the age range of 18-30 years in two groups, including the case (with ankle instability, n=20) and healthy control (without ankle instability, n=20) groups. The electrical activity of selected leg and thigh muscles was recorded during three functional patterns, i.e., the overhead squat, overhead squat with heel lift, and single-legged squat, by electromyography apparatus. The investigated muscles consisted of the gastrocnemius medialis (GM) muscle, the gastrocnemius lateralis (GL) muscle, the tibialis anterior (TA) muscle, the fibularis longus (FL) muscle, the soleus (SO) muscle, the vastus lateralis (VL) muscle, the vastus mediali (VM) muscle, and the biceps femoris (BF) muscle.
Results: The activity of the VM, VL, BF, and TA muscles in the single-legged squat and the activity of the VM, VL, BF, SO, and TA muscles in the overhead squat showed a statistically significant increase in the case group compared to the control group (P<0.05). The highest difference in the muscle activity of the two groups was observed in the overhead squat with heel lift movement, which in this movement, except for the GL muscle, there was a statistically significant increase among all other muscles (P<0.05).
Conclusion: Functional movements culminate in increasing the electrical activity level of leg and thigh muscles in female athletes with ankle instability.

Background and Objective: Breast cancer has a high prevalence and mortality rate in the world and also in Iran. Neoadjuvant chemotherapy (NAC) is one of the treatment methods to improve patient survival. This study aimed to determine the response rate to NAC in patients with locally advanced breast cancer based on common molecular receptors.
Methods: This descriptive-analytical study was conducted on 100 patients with breast cancer (mean age= 41.14±10.06 years) referring to the surgical clinic of the Fifth Azar Educational and Therapeutic Center in Gorgan, Iran during 2013-18. Patients without distant metastasis underwent NAC treatment regimen followed by surgery. Demographic characteristics, types of drugs, and molecular receptor characteristics, and their response to treatment were recorded in a checklist. Treatment response and overall patient survival were evaluated.
Results: The mean tumor size before NAC was 3.01±2.47 cm (range= 0-8, median= 2) and 16% were determined to be grade one, 52% were determined to be grade 2, and 32% were determined to be grade 3. Thirty-six percent of patients had a positive family history. Forty-six percent were estrogen receptor (ER) positive, 40% were PR positive, 22% were human epidermal growth factor receptor 2 (Her-2) positive, and 78% were Her-2 negative. Thirty-six percent had a Ki-67 index greater than 30%. Eighteen percent of patients had a complete pathological response, and 82% had a partial or negative response. In terms of family history of breast cancer, Her2, ER, progestrone receptor (PR), Ki-67 receptor status, histological grade, tumor size, and axillary lymph nodes, there was a significant statistical difference between the two groups with and without complete pathological response (P<0.05).
Conclusion: The rate of complete pathological response to NAC in patients with locally advanced breast cancer was 18%.

Background and Objective: Restrictions imposed during the coronavirus disease 2019 (COVID-19) pandemic led to a decrease in physical activity levels across various age groups, particularly among students. This study aimed to determine the effect of eight weeks of corrective exercises on musculoskeletal pain levels in 13-15-year-old students.
Methods: This clinical trial was conducted on 101 students (44 girls and 57 boys) aged 13 to 15 experiencing musculoskeletal pain in various body parts in Bandar Mahshahr, Khuzestan Province, during the second half of the academic year 2021-2022. Participants were selected based on the Adolescent Nordic Musculoskeletal Questionnaire (NMQ), considering only the first question regarding the presence or absence of pain in each of the nine body regions (neck, shoulder, elbow, hand, upper back, lower back, pelvis, knee, and ankle) in the past seven days. A score of 1 was assigned to the presence of pain and 0 to the absence of pain. Participants were randomly assigned to two groups of 60: A control group and an intervention group. The intervention group performed corrective exercises at home for eight weeks, with three sessions per week, each lasting 40 minutes. No intervention was provided to the control group. Musculoskeletal pain levels in the neck, shoulder, upper back, elbow-arm, wrist, lower back, knee, and ankle were then compared in the pre-test, post-test, and follow-up.
Results: The mean and standard deviation of the total pain scores for the intervention and control groups were 1.32±0.41 and 1.33±0.46 in the pre-test, 1.01±0.08 and 1.34±0.46 at the post-test, and 1.17±0.36 and 1.11±0.31 at follow-up, respectively. Results revealed that eight weeks of corrective exercises significantly reduced musculoskeletal pain levels in the students’ neck, shoulder, upper and lower back, elbow, knee, wrist, ankle, pelvis, and thigh (P<0.05); however, this improvement was not sustained at the follow-up.
Conclusion: Performing corrective exercises reduced musculoskeletal pain levels in the neck, shoulder, upper and lower back, elbow, knee, wrist, ankle, and pelvis and thigh of 13-15-year-old students; however, the benefits were not sustained when the exercises were stopped.
