Abstract
Radiolucent lesions of the vertebrae, especially the cervical vertebrae are commonly encountered by the orthopedic surgeons and neurosurgeons dealing with spinal column disorders. Considering the unavailability of highly sophisticated and reliable facilities to reach the exact diagnosis before starting appropriate therapy. Trial of medical therapy is suggested to be worthy before attempting for wide surgical intervention. Presenting a very interesting case, we have reviewed the lesions presenting as radiolucent areas in plain X-rays and planned a step by step discussion for differential diagnosis. Special stress has been done on the endemicity of tuberculosis and brucellosis in Iran.

Abstract
Introduction: The bone mass density (BMD) may vary in different countries due to different genetic and environmental factors. This study was performed to determine the BMD of the normal population in Iran.
Methods and Materials: Subjects were selected randomly from different works and social classes in Tehran (from the lowest to the highest). For each decade and sexes, 20 normal subjects were selected (140 men and 140 women). BMD was measured with a Hologic 1000 plus machine by dual energy x-ray absorptiometry (DEXA) method for the lumber spine (L1, L2, L3, L4, L1-L4) and the femoral neck (neck, trochanter, intertrochanter, ward, total). Data were treated by polynomial approximation (3 rd degree). The obtained curves were compared with the standard Hologic curves for Caucasians.
Results: In female the peak bone mass (PBM) was 1.019 g/cm² for the lumbar spine and 0.832 for the femoral neck. In male the peak bone mass (PBM) was 0.987 g/cm² for the lumbar spine and 0.907 for the femoral neck. The BMD of both lumbar spine and femoral neck were lower than the Hologic standards. For the lumbar spine the mean difference was 6.5 percent (2 to 21 percent, CI=1) for women and 13.8 percent (2 to 36 percent, CI=1.45) for men. In femoral neck the mean difference was 5.4 percent (2 to 16 percent, CI=0.96) for women and 4.6 percent (1 to 14 percent, CI=0.96) for men.
Conclusion: The BMD of the lumbar spine and the femoral neck was lower in Iranian compared to the Hologic standards for Caucasians. This was seen in all age groups and in both sexes. It was less pronounced for the PBM in spine was lower in men than woman. The lower BMD of the spine in men was also seen in a cohort of patients with different diseases (inflammatory and non-inflammatory).

Abstract
Background: Pulmonary involvement is a common and serious complication of rheumatoid arthritis. This cross sectional study sought to determine the prevalence of pulmonary disease in patients with rheumatoid arthritis on the basis of history, physical examination, chest X-ray and PFT.
Materials and Methods: 103 patients (81 Women, 22 Men) fulfilling the ACR (American College of Rheumatology) criteria for RA (Rheumatoid arthritis) were consecutively included in a cross sectional study. Detailed medical (including respiratory symptoms and the disease activity symptoms) and drug and occupational histories and smoking were obtained. All patients underwent a complete pulmonary and rheumatologic examination and conventional chest radiography. All patients underwent PFT that comprised spirometry and body plethysmography.Results for PFTs were expressed as percentage of predicted values for each individual adjusted for age, sex, and height.
Results: On the basis of history: Their mean age was 43.3 ± 2.6 years (range: 17-74) and the mean duration of the disease was 69.3 ± 15.6 months. Rheumatoid factor was positive in% 61.2. No patients were 0.5Pack/Year smoker in whole life. Prevalence of pulmonary involvement based on radiographic and pulmonary function test detected in 41 patients (39/7%). The most frequent respiratory clinical finding was dyspnea (33%), (NYHA grade I in 17.5% and NYHA grade II in 15.5%), Cough (with or without sputum) in 13.6 %, Crackle was the most sign in pulmonary examination (5.8%). Chest X-ray was abnormal in 13.3 % that the most common finding in this study was reticulonodular pattern in 20 patients (19.4 %), and pleural effusion detected in 7 patients (6.7%). PFT was abnormal in 30 patients (29.1 %). A significant decrease of FEF 25%-75% below 1.64 SD. Small airway involvements was the most abnormal finding of PFT. No relation between rheumatoid arthritis disease activity (ESR>30, Morning stiffness>30', Anemia, thrombocytosis) with pulmonary disease was seen.
Conclusion: This study suggests a high prevalence of lung involvement in patients with rheumatoid arthritis.Therefore we recommend a complete investigation in patients with RA with any respiratory symptom.

Abstract
Background: Scleroderma is an important chronic disease with unknown ethiology and two subtypes: limited type: Skin involvement limited to distal of extremity and face. Diffuse type: Skin involvement is both distal and proximal of extremity, face and thrunk. Thyroid dysfunction is a main problem in these patients but there is no published data of Iranian scleroderma patients
Methods: This is a cross-sectional study to determine the prevalence of hypothyroidism (clinical, subclinical and autoimmune) in patients with scleroderma 125 patients with scleroderma selected and T3, T4, TSH Anti Tpo Ab and Anti TG Ab measured in them.
Results: 33 patients with scleroderma had hypothyroidism. (%26/4). Two patients with scleroderma had hyperthyroidism. (%1/6). %12/8 had clinical hypothyroidism. And %13/6 had subclinical hypothyroidism, %33/3 of patients with subclinical hypothyroidism and positive autoantibody had limited type. Where as %66/6 of patients with subclinical hypothyroidism and autoantibody had diffuse type, %28/5 of patients with clinical hypothyroidism and positive auto anti body had limited type. Where as %71/4 of patients with clinical hypothyroidism and auto anti body had diffuse type. All of patients with hyper thyroidism had diffuse type and autoantibody positive.
Conclusion: It seems hypothyroidism has an increased prevalence in patients with scleroderma and we suggest that thyroid function test must be done in primary evaluation of these patients

Abstract
Background: The cause of osteoporosis is multifactorial and many dietary factors are important in the prevention of this disease. Antioxidants as free radical scavengers may influence osteoporosis by reducing the effects of oxidative stress that may be associated with bone loss. Vitamin E is an important antioxidant that protects polyunsaturated fatty acids (PUFA) in cell membranes from oxidation. There are only two studies regarding vitamin E plasma levels in subjects suffering from osteoporosis. The purpose of this study was to investigate the association between plasma vitamin E levels and bone mineral density (BMD) in Iranian patients.
Methods: Subjects were consecutively recruited between May and September 2005 from among a total of approximately 1000 people referred for instrumental screening for osteoporosis to the Jami Clinic in Tehran. Inclusion criteria for the study group were: a femoral neck T-score of -1 or less, osteopenia, severe osteopenia and osteoporosis. A total of 137 subjects were enrolled. According to their femoral and spinal BMD scores, 54 persons were selected as a control group. The control group consisted of subjects with a femoral neck T-score and spine T-score of -1 or more. In selecting the case group, only the femoral BMD score was used. Plasma vitamin E was measured, after extraction with methanol, by HPLC with UV detection at 280 nm. Methanol, deionized water and butanol (90:4:6) was used as a mobile phase with a C8 column. The flow rate was 1.0 ml. min-1 and the acetate ester of vitamin E was used as an internal standard.
Results: The results show no significant difference in plasma vitamin E between the control and case groups, however linear regression analysis does reveal a significant difference between the T-score and plasma vitamin E.
Conclusion: Deceleration Femoral bone Density during osteoporosis will be Accelerated with Decrease of Vitamin E Antioxidant level.

Abstract
Background: Both isokinetic testing and functional tests are commonly used to evaluate anterior cruciate ligament reconstructed (ACLR) patients. The object of this study was to evaluate motor performance of the knee and determine the relationship of isokinetic test scores to scores on a variety of lower extremity functional tests.
Methods: Ten healthy subjects and eleven ACLR patients at least six months after surgery performed the following: knee isokinetic tests at 60 and 180 deg/sec three functional tests including leg vertical jump, single hop, and triple cross-over hop for distance. The International Knee Document Committee Subjective Knee Evaluation Form (IKDCSKEF) was used to score the self-assessment of each study participant. Paired T-test was used to compare the involved and uninvolved knee. Pearson correlation coefficients were used to determine the relationship between the scores on the isokinetic test and functional tests. Significance was determined by P<0.05.
Results: IKDCSKEF score was significantly lower in patients than control subjects. Quadriceps peak torque and functional test scores were significantly lower in the involved knee of the ACLR subjects compared to the uninvolved knee. Correlation coefficients of isokinetic peak torque to body weight and functional testing were not significant in patients or control subjects, whi1e the limb symmetry index (LSI) of the quadriceps isokinetics peak torque to body weight and the LSI of the functional tests were significant (r = 0.54 to 0.97).
Conclusion: These results indicate a significant relationship between the LSI of various functional tests and the LSI of isokinetic testing among ACLR patients. Thus, in situations where an isokinetic dynamometer is not available, the LSI of functional tests can be used to estimate quadriceps deficiency for ACLR patients.

Abstract
Background: Sudden sensorinueural hearing loss (SSNHL) is a baffling condition for patients, and its etiology, audiologic characteristics, prognostic factors, and treatment are still controversial.
Methods: In this prospective study, we performed pure tone audiometry (PTA), impedance acoustics (IA), auditory brainstem responses (ABR), otoacoustic emissions (OAE), and transiently evoked otoacoustic emissions (TEOAE) before beginning treatment for 53 patients with SSNHL. We then entered each patient, randomly and alternately, in one of two treatment groups: oral steroids + acyclovir vs. intravenous urographin.
Results: In 22 (41.5%) of the 53 patients (22 female, 31 male), we found negative or no signal to noise ratio and overall correlation in TEOAE. Furthermore, 26 cases (49%) had positive overall correlations less than 50%, and five cases (4.4%) had overall correlations >50%. Although 15 cases (28.3%) responded well, 20 cases (37.7%) showed only a partial response, and 18 cases (33.9%) had poor or no response to our treatment. The mean value for overall correlation in the three subgroups of patients (no response, partial response, and complete response) was -3.5% (±1/16%), + 11% (±1.99%), and +36.6% (±3.07%) respectively (P = 0.01). From 52 cases, 20 had no reproducible wave in ABR (38.5%), three cases had abnormal ABR with normal OAE, all of which responded completely to treatments. Thirteen cases had abnormal ABR and OAE, none of which responded to treatment, and six cases had normal ABR with abnormal OAE, which often responded to treatment.
Conclusions: ABR and OAE may be useful in the diagnosis of SSNHL and determining the site of such lesions as ischemia or neuropathy. The overall correlation (and S/N ratio) in TEOAE is a valuable prognostic factor in SSNHL.

Abstract
Background: Heat-shock proteins are part of a strictly controlled biological system that allows organisms to respond to environmental stresses. Different proinflammatory cytokines are present in the synovial tissue of rheumatoid arthritis patients. Such tissues respond to stress and induce heat-shock proteins. In addition, synovial cells are exposed to mechanical stress caused by joint motion. The effects of mechanical stress on the metabolism of the synovial cells may be substantial, even pathogenic. Heat-shock proteins are often implicated in the pathogenesis of rheumatoid arthritis. Here, we compare the levels of heat-shock protein 70 from the synovial fluid of rheumatoid arthritis and osteoarthritis patients.
Methods: Synovial fluid samples from 34 rheumatoid arthritis patients and 34 osteoar-thritis patients were analyzed for heat-shock protein 70 by an ELISA method. Statistical analysis was performed using independent T-test and one-way ANOVA. Differences were considered statistically significant at p< 0.05.
Results: The mean value of synovial fluid heat-shock protein 70 levels in rheumatoid arthritis patients was 156.30 ±128.51 and that of osteoarthritis patients was 14.98 ±11.58. The differences were statistically significant at p<0.0001. For seven rheumatoid arthritis patients suffering from mechanical knee pain, synovial fluid analysis revealed non-inflammatory effusion. The mean value of synovial fluid heat-shock protein 70 level in inflammatory synovial fluid of rheumatoid arthritis patients was significantly higher at 191±121.73 and that of non-inflammatory synovial fluid from rheumatoid arthritis patients was 21.93 ±10.06 (p< 0.05).
Conclusion: The level of heat shock protein 70 is higher in inflammatory arthritis than in non-inflammatory arthritis. Considering that patients with rheumatoid arthritis are known to have a hypertrophic synovial-lining layer, and that heat-shock protein 70 is known to protect cells against a variety of toxic conditions as well as apoptotic death, further research is needed to determine if heat-shock protein 70 induction is a sign of significant changes in the cellular and tissue metabolism or is actively participating in the pathogenesis of rheumatoid arthritis. |

Abstract
Background: Osteoporosis threatens the aged population especially the menopausal
women and can lead to life long disability and death. Appropriate knowledge and behavior
have an important role in prevention of osteoporosis. In this study the knowledge, attitude
and behavior of women regarding osteoporosis is assessed and compared in different age
groups.
Methods: This cross sectional study includes 390 women in reproductive, premenopausal
and menopausal age groups who had come to Shariati hospital clinics and each had
answered the designed questionnaire. The questionnaires were scored and analyzed.
Women’s knowledge, attitude and behavior were assessed and compared by X2 test in the
three age groups and P<0.05 was considered significant.
Results: 15–30% of women didn’t know what osteoporosis is and in 380 of them attitude or
behavior was not good. Education had a significant effect on knowledge of women in
reproductive and premenopausal ages (P=0.002, 0.04 respectively), but had no effect on
their attitude or behavior. Age had a significant effect on knowledge and attitude (P=0.001)
but had no effect on behavior. Age had significant effect on the knowledge that exercise
can prevent osteoporosis (P=0.014) but not on attitude or behavior. Age had no effect on
knowledge, attitude or behavior of daily calcium intake to prevent osteoporosis. (P=0.123,
0.12, 0.153 respectively) 93% to 95% of women thought the risks of osteoporosis are less
than cardiovascular disease or breast cancer.
Conclusions: 15–30% of women didn’t know what osteoporosis is. The total knowledge
about osteoporosis was low. Although 22-75% of women younger than 54 years old had
knowledge about the predisposing factors but their attitude or behavior was not good.

Abstract
Background: Post-tonsillectomy pain is often severe and usually prevents patients from routine eating and drinking. A new option for reducing postoperative pain is "preemptive analgesia", the pre-, intra- or post-operative administration of analgesic agents. Ketamine, an N-methyl D-aspartate receptor antagonist, has recently received attention for this aim. Herein, we study the effect of submucosal injection of ketamine in the tonsillar bed for the reduction of post-tonsillectomy pain.
Methods: In this double-blind clinical trial, three groups of patients underwent infiltration of 0.5mg/kg ketamine, 1mg/kg ketamine or normal saline in their tonsillar bed. Age, sex and weight of patients, duration of surgery, systolic and diastolic blood pressure (before and after surgery), volume of blood loss, reoccurrence of bleeding, time to initiation of oral intake, nausea, vomiting, pain score and dysphasia were recorded in information sheet. Data analysis was performed by one-way ANOVA and chi squared tests, with significance at a P value of <0.5.
Results: There is no significant difference between the three groups with regard to age, sex, weight, duration of surgery, blood pressure (before surgery), volume of blood loss, nausea and vomiting. However, for the ketamine groups, pain score, dysphasia, need for opioid administration and time to initiation of oral intake is significantly lower (P<0.00). Reoccurrence of bleeding was observed in one patient in the lower-dose ketamine group, which is not statistically significant. The effectiveness of the two doses of ketamine is similar, with no statistical difference between the two groups (P=0.84).
Conclusions: This study demonstrated that a submucosal injection of ketamine into the tonsillar bed preoperatively is a safe option for reducing post-tonsillectomy pain, dysphasia, need for opioid and time to initiation of oral intake, without increasing the risk of excessive bleeding, reoccurrence of bleeding, nausea and vomiting.

Abstract
Background: There are several evidences that genetic factors besides environmental triggers have important role in initiating the rheumatoid arthritis (RA). The aim of this study was to investigate the association of rheumatoid arthritis with different subtypes of HLA DR4 in Iranian patients.
Methods: In an un-matched case control study, 110 rheumatoid arthritis patients (case) and 56 knee osteoarthritis patients (control) of outpatient clinic in Shariati Hospital were entered to the study. After blood sampling from case and control groups, DNA was isolated by using salting-out method and HLA DR4 and its subtypes were detected. Association of HLA DR4 and its subtypes with rheumatoid arthritis, rheumatic factor and clinical manifestations of diseases was evaluated.
Results: Eighty nine (80.9%) of rheumatoid arthritis patients were female and 21 were male. Thirty four of the RA patients (30.9%) and eleven subjects from the control group (19.6%) were HLA DR4 positive (p=0.12). The most frequent subtype of HLA DR4 in RA patients was 0404 and in control group was 0401 (p=0.03). There were not statistically significant association between HLA DR4 and age of disease onset, family history, morning stiffness and rheumatoid factor. Joint swelling and tenderness had association with HLA DR4 (p=0.04 and p=0.03).
Conclusion: Although there were no statistically significant association between rheumatoid arthritis and HLA DR4, but prevalence of this HLA was higher in patients than control. It is possible that in some ethnics, other HLAs may have role in pathogenesis of disease.

Abstract
Background: Osteoarthritis is the most common form of arthritis in the world. This study presents the evidence on the prevalence of symptomatic hand osteoarthritis in urban community. To add to the evidence on the prevalence of symptomatic hand osteoarthritis in urban community.
Methods: Inhabitants (age≥15 yrs) in 22 randomly selected districts (Tehran) participated in a Community-Oriented Program for Control of Rheumatic Diseases (COPCORD) evaluating major rheumatic disorders, including osteoarthritis. Eventually, 10, 291 inhabitants completed a Questionnaire (75% response-rate). Trained interviewers asked participants whether they had had any pain, swelling, tenderness, or morning stiffness in the right/ left hand during previous seven days. Participants underwent a complete physical examination if they had any musculoskeletal complaint or extra-articular manifestation of rheumatic disease. Osteoarthritis was defined as presence of palpable nodules (Heberden’s/ Bouchard’s nodes, CMC1’s squaring), pain, tenderness, swelling, or a combination of them on that joint (DIP-PIP-MCP-CMC1). Clinical hand osteoarthritis was positive if at least one joint showed osteoarthritis.
Results: Symptomatic hand osteoarthritis was present in 2.8%(CI 2.3-3.4) (52.6% female, mean age 37.1±16.3). Prevalence was higher in females (4.3% vs. 1.3%, p=0.000) and increased with age (0.1% in people <30 versus 23% in people >70, p=0.000). The most common signs in the DIP, PIP and CMC1 joints were bony enlargement, followed by tenderness and pain on movement.
Conclusions: our study confirms the evidence of high prevalence of symptomatic hand osteoarthritis in an urban community. The prevalence, pattern of hand joints involvement and relationship with age and sex in this study performed in an Eastern community resemble those in Westerners, which calls for further attention by appropriate services.

Abstract
Background: Systemic Lupus Erythematosus (SLE) is a prototypic autoimmune disease with diverse clinical manifestations in association with autoantibodies to components of the cell nucleus. SLE as a chronic autoimmune disease has a worldwide distribution. There is a wide variation in the natural history of SLE among different ethnic and geographic groups. Our SLE registry is one of the largest series in Asia-Pacific region. The aim of this study was to show the manifestations of SLE in Iranian patients.
Methods: This study is on clinical and Para clinical manifestations of SLE according to the database of the Rheumatology Research Center (RRC), Tehran University of Medical Sciences as a major referral center for rheumatic disease in Iran during the period of 1976 to 2009.
Results: A total of 2143 SLE patients were studied. The female to the male ratio was 8.8:1 and the mean age at the presentation was 24.2± 10 Years. Prevalence of clinical manifestations included: musculoskeletal, cutaneous, renal, neuropsychiatric, pulmonary, cardiac and hematologic were 85.2%, 83.1%, 66.6%, 24%, 22.3%, 17.5% and 67.1% respectively. There were seen positive FANA in 78.3% and anti-DNA in 70% of patients. Overlap syndrome and positive family history with other autoimmune diseases were detected in 14.9% and 3.4% of patients respectively.
Conclusion: The prevalence of some manifestations (such as cutaneous and renal involvement) in our patients were similar to those of nearby countries (with similar climate), while other manifestations (such as hematologic and joint involvement) were similar to the European countries (with similar ethnicity). Genetic and/or climatic factors may lead to different presentations of lupus.

Abstract
Background: Pruritic Urticarial Papules and Plaques of Pregnancy (PUPPP)
is a specific dermatosis of the third trimester of pregnancy,
commonly seen in primigravid women.
Case presentation: A 24-year-old
primigravida woman who had developed a rash immediately after delivery was
admitted to Razi Hospital
in Tehran, Iran. She had an erythematous
eruption, particularly concentrated on the abdominal striae with umbilical
sparing and involvement of limbs and extremities. Skin biopsy of the lesions on
the lower abdomen, showed superficial perivascular infiltrates with occasional
neutrophils and eosinophils. Both direct and indirect immunofloresence assays
were negative. The patient was ultimately treated with topical clobetasol
butyrate and oral chlorpheniramine for pruritus. Within a week, the lesions and
the itchings had disappeared completely.
Conclusion: Pruritic urticarial papules and plaques of
pregnancy are often, but not always, seen during the third trimester of
pregnancy, but sometimes they present in postpartum period without any prior
manifestations during pregnancy.

Abstract
Background: Judicious use of antibiotics is essential considering the growth of antimi-crobial resistance and escalating costs in health care. Ceftriaxone is a third-generation cephalosporin used widely for the treatment of various infections in outpatient and in-patient. The purpose of this study was to evaluate the ceftriaxone utilization before and after implementation of guidelines and physicians education.
Methods: A descriptive cross-sectional, before-after intervention study was performed in 6 wards of a teaching hospital in Tehran, Iran. The study was conducted in three phases: pre-guideline, educational interventions and post guideline implementation. The pre intervention phase included chart analysis of current ceftriaxone use in 200 consecutive patients from the representative wards included in the study. The educational interventions included preparation and distribution of ceftriaxone guidelines as pamphlets among physicians working in the studied wards. Also the clinical pharmacist returned to each ward and trained physicians regarding the correct use of ceftriaxone. In the post intervention phase immediately after the instruction, and in the follow up phase, one month later, a prospective analysis of ceftriaxone utilization was performed by chart review of 200 patients to detect changes in ceftriaxone utilization pattern.
Results: Four hundred cases were evaluated during study (200 before and 200 after physician’s education). The correct indication of ceftriaxone was 93% and 96% before and after the educational interventions respectively. Analysis showed that correct indi-cation of ceftriaxone did not change significantly before and after education (P= 0.188). Regarding to proper administration (dose, interval and duration) ceftriaxone utilization significantly changed after education (P< 0.001).
Conclusion: Adoption of the guidelines with associated training resulted in significant improvement in ceftriaxone administration pattern in the hospitals.

Abstract
Background: Cooling is one of the main processes in bone temperature decrement, while drilling. this experiment was conducted for examination of alcohol effect as cooler in prevention of thermal necrosis.
|
Methods: Bovine femur bone was considered as specimen and inclusions criteria for this study were: femur bone, cortical area and without bone periosteum. Drilling process was conducted by two types of k-wire- Trocar and Diamond, three speeds and three feed rates and in the time of march, 2016 in the place of university of Isfahan, Iran. Two type of thermometer- K-thermocouple and infrared thermometer- were used for temperature measurement, and all data were logged by data logger. Drilling processes were conducted by milling machine with ability of table movement for feed rate parameter. Method of alcohol usage in cooling was in form of conducting alcoholic gauze with k-wire while rotating.
Results: Totally in the cases of trocar and diamond wires, while were cooled by alcohol, the risk of bone necrosis decreased about 44.44% and 66.66%. All temperature data were logged by changing parameters. maximum temperature, 94.5 °C, belonged to trocar wire in a non-cooling condition and after usage of cooler it decreased to 75 °C. In the usage of diamond wires, the maximum temperature was recorded 71 °C and the temperature while using alcohol was 51 °C. Diamond wire had better result in both conditions of cooling and no cooling, and this is related to geometric differences between two types of wires.
|
Conclusion: Due to obtained data from examination, utilization alcohol can have an important influence on final bone temperature decreasing. The way of using alcohol was in the style of attrition soaked gauze onto wire while insertion.

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.

Abstract
Background: Application of Hybrid 6 degrees of freedom fixation could lead to space motion in each 3 anatomic plates together and decrease the time of complex deformities correction. This study is an investigation on the function of hybrid external fixation and the influence of it on decreasing the treatment time. About this case utilize of Ortho-SUV Frame (OSF) system is explained for the first time in Iran and report of its novel. These robotic systems are divided into two groups: active and passive, about active system all movements are done by actuators in joints and links. And in passive, the system needs an operator or patient to actuates Sturats by hand.
Methods: The femur bone has been investigated was non::::union:::: with deformity in sagittal, frontal and transversal planes. Ilizarov external fixation was applicate firstly, with this condition that the OSF systems jacks were replaced instead of simple rods in side of fracture. Software work was done on February of 2016 in Ayatollah Taleghani Hospital, Tehran, Iran. Fractures were happened in a car accident and some other operating were perforemed for this patient without any result.
|
Results: The correction of studied deformity needs 3 planar moving. Acting this movement by Ilizarov requirements 33 mm displacement in frontal plane, 12 mm horizontal distraction and 48 mm displacement in sagittal plane. Due to the rate of correction in Ilizarov which is 1 mm per day, this bone needs 93 days for general correction and three times changing in shape of rings connections. While, by using the hybrid external fixation, all displacements were corrected in 46 days and first connection had supported all planes.
Conclusion: According to that the decreasing of treatment time is one of the main goal, the hybrid external fixation systems could be an appointment choice in complex deformities and replaced with some common fixation. In addition to, using of updated software increases the accuracy of displacement.

Abstract
Background: According to the direct connection between congenital hypothyroidism and iodine deficiency in pregnant women, also relatively high incidence of congenital hypothyroidism in some areas of Kerman province, especially Raver district located in North of Kerman province, this study was performed to determine and compare the urinary iodine concentration (UIC) in pregnant women referring to health centers.
Methods: This cross-sectional study was done during March 2014 and May 2015. Inclusion and exclusion criteria to be considered and UIC were measured by spectrophotometry in 384 and 374 pregnant women in Ravar and Kerman cities, Iran. Sampling method for this study was all of pregnant women in Ravar and random stratified sampling in Kerman. data were collected using a structured questionnaire. All statistical analyses were performed using SPSS Software, version 20.0 (IBM SPSS, Armonk, NY, USA). Chi-square test, Pearson's correlation coefficient and Logistic regression were used for associations and differences.
Results: The mean UIC was 200.21 µg/L in pregnant women of Ravar and 238.79 µg/L in pregnant women of Kerman. 22.7% of pregnant women were with low concentrations of iodine, 57.8% within the normal range and 19.5 percent were with high iodine concentrations in Ravar. While 5.3 percent of pregnant women were with low concentrations of iodine, 54.5% were within the normal range and 40.1% were with high UIC in Kerman. There were no significant differences between demographic variables and UIC in the two regions (P> 05/0). Multivariate regression models showed significant connections between the residence and UIC pregnant women (P< 0.001).
Conclusion: The results of this study showed that UIC in pregnant women of Ravar was significantly lower than Kerman and the place of living can be considered as a predictor of UIC in pregnant women.

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.
