Abstract
Background: H.pylori is one of the most common chronic bacterial infections in population so more than 85 percent are infected in Iran. H.pylori can cause different gastrointestinal disease like gastritis, peptic ulcers and even cancer. One of the effective factors in pathogenesis of bacteria is cytotoxin associated with gene A (cagA). Strains with cagA gene are more virulent. The aim of this study was to determine the frequency of cagA gene of H.pylori in patients with gastric disorders who were admitted to Imam Hossein Hospital, Tehran. Materials and Methods: In this descriptive study, DNA was extracted from 84 paraffin- embedded tissues using QiaAmp tissue kit. H.pylori was verified with PCR of 16sRNA sequences specific for Helicobacter spices and cagA gene was determined using specific primer by the PCR method. The prevalence of cagA gene in three clinical groups gastritis, gastric ulcer, and atrophic patients was compared. Results: Among 84 H.pylori positive isolates ,72 biopsy samples were positive for 16sRNA (85.7%) and 46 (63.9%) for cagA. The prevalence of cagA positive strains in peptic ulcer patients (43.5%) was greater than in those with gastritis (30%). Conclusion: Results showed that Helicobacter pylori strains with cagA are more common in patients with peptic ulcer and cancer.

Abstract
Background: Mothering handling plays an important role in the daily life of children with cerebral palsy (CP) and their mothers, so that the greatest amount of handling of children with CP is done by the mothers at home. The study aimed to explore the process of mothering handling in the children with CP at home.
Materials and Methods: This qualitative study was conducted using grounded theory methodology in Tehran. The purposeful sampling followed by theoretical sampling. Selecting participants continued to achieve theoretical saturation. The number of participants was 26 including 15 caregivers, 3 children with cerebral palsy, 5 occupational therapists, 1 physiotherapist, and 3 rehabilitation manegers. The main source for gathering data was in-depth, semi-structured interviews. Data were analyzed by Corbin & Straus method (2008).
Results: Six categories/themes emerged from the data, including: motherly care, confronting with unusual co-occupation, confusion in roles, effort to special care, dynamic management of handling, and continuing care. The central category, confrontation with unusual co-occupation, represented the main theme of the research, and all major categories had been related to it.
Conclusion: The results of this research could provide broad perspective to rehabilitation therapists, managers and policy makers for understanding the needs, meeting challenges and concerns of caregivers and children with CP and designing a comprehensive plan for handling process of children with CP and helping them to be empowered for achieving the proper management and effective handling.

Abstract
Background and Aim: Musculoskeletal disorders are mainly prevalent among college students who experience direct contact with patients. This study aimed to determine the prevalence of musculoskeletal pains among Rehabilitation, Dentistry, and Nursing students at Arak University of Medical Sciences in 2017-2018.
Methods & Materials: In this cross-sectional descriptive study, 538 students of Arak University of Medical Sciences were recruited using the convenience sampling approach. Variables included age, sex, body mass index, study field, hours of using smartphone per day, and nine symptom sites being neck, shoulders, upper back, elbows, low back, wrist/hands, hips/thighs, knees, and ankles/feet. The researchers assessed the musculoskeletal pain by using the Nordic questionnaire and demographic questionnaire. Statistical analysis was performed using SPSS V. 18.
Ethical Considerations: The Research Ethics Committee of Arak University of Medical Sciences approved this study (Code: IR.ARAKMU.REC.1397.253).
Results: In this study, 538 students (205 males and 333 females) were studied with Mean±SD age of 22.04±2.53 years old. The results showed that the prevalence of musculoskeletal pain in the spine (neck 29.4%, upper 24.3%, and lower back 37.2%) was higher than in upper and lower extremities. Musculoskeletal pain in the shoulder, upper, lower back, and thigh were significantly different based on sex. Also, musculoskeletal pain in the neck and ankle, and foot were significantly different based on age (P<0.05). There was a significant difference between musculoskeletal pain of back and ankle based on smartphone use hours per day.
Conclusion: This study suggested that rehabilitation, nursing, and dentistry students are at risk for musculoskeletal pain, especially in the lumbar, cervical, and upper back.
