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.

Background: Thyroid carcinoma is the most common endocrine malignancy and approximately accounts 2% of all cancer cases. Medullary thyroid cancer (MTC) is an endocrine tumor with differentiation of Parafollicular or C-cells and is categorized into hereditary or sporadic types. Medullary thyroid carcinoma approximately accounts for 5-10% of all thyroid carcinoma. Germ-line and somatic mutations in exons 10 and 11 RET (Rearranged during Transfection) proto-oncogene are responsible for the occurrence of the familial and sporadic types, respectively. Calcitonin is a key marker in MTC diagnose and has been demonstrated to be highly sensitive for differential diagnosis prognostic assessment, follow-up and evaluation of MTC treatment. The aim of this study was to investigate the relationship between plasma levels of calcitonin in MTC patients with or without RET mutation.
Methods: In this cross-sectional study, the population consist of MTC patients who have referred to the endocrine and metabolism research center of Shahid Beheshti University of medical sciences since October 2013 till October 2016. Genomic DNA was extracted from peripheral blood leucocytes using the standard salting out/proteinase K method. Nucleotide change detection in exons 10 and 11 was performed using polymerase chain reaction (PCR) and direct DNA sequencing methods. Participants were then divided into two groups with or without mutation (43 individuals in each group). Plasma calcitonin levels were determined by enzyme-linked immunosorbent assay (ELISA) method in both groups.
Results: Evaluation of the level of plasma calcitonin in 43 patients with a molecular mutation in RET proto-oncogene (mean age 31 years) and 43 patients without molecular mutations in RET proto-oncogene (mean age 43 years) were 7.6 pmol/mL and 3.07 pmol/mL respectively. This difference is statistically significant (P=0.0014).
Conclusion: Routine measurement of calcitonin has been investigated as a screening method for the diagnosis of medullary thyroid carcinoma patients. Nevertheless, additional data are required to definitely support routine measurement of calcitonin due to the role of RET proto-oncogene.

Uterine sarcomas comprise a group of rare tumors with different tumor biology, natural history and response to treatment, contain just 3-7% of total uterine malignancies and about 1% of all gynecologic cancers. Although they cause important part of women death due gynecologic cancers. These tumors have aggressive behavior and high recurrence rate, even when confined to the uterine corpus at the time of diagnosis. The most common of uterine sarcomas is leiomyosarcoma. The incidence of leiomyosarcoma is increased after age 50. Traditionally, carcinosarcomas were named as Malignant Mixed Mullerian tumor (MMMT), but in recent classification according to their pathologic structure and its behavior, these tumors are classified as carcinomas. The rare group of sarcomas is endometrial stromal sarcoma (ESS), which occurres in younger women. In a medical studies search from 2000 to 2017, all kinds of uterine sarcomas, pathologic diagnostic methods, primary treatment and supportive treatment have been analyzed. Last histological classification is based on FIGO 2009 and WHO. According to such classification, sarcomas divided into three subtypes: leiomyosarcoma, endometrial stromal sarcoma and carcinosarcomas. Diagnosis of sarcoma before treatment and discrimination from benign myoma by current diagnostic methods is difficult. Preoperative endometrial sampling identifies only 25% of sarcomas. It may be the myometrial origin of tumor. Currently, MRI, ultrasound and PET scan may be used for the diagnosis of tumor. The gold standard of treatment is complete and intact resection of tumor considereing free margins. In advanced or recurrence disease, cytoreductive surgery followed by chemotherapy is the choice of treatment. If technically it is not possible or there are extra abdominal metastases, palliative chemotherapy should be considered. Combination of gemcitabine and docetaxel is an acceptable choice. Recent studies are going to approve the effective role for targeted agents with or without cytotoxic chemotherapy in these group of aggressive tumors. The only drug in this group has approval is pazopanib. However, it did not achieved acceptable responses in phase I, II studies. As regards of tumor biology and inappropriate response to chemotherapy and radiotherapy, sarcoma have poor prognosis in all stages.

Immunotoxins such as pseudomonas exotoxin are Molecules with a unique structure like toxin-antibody part. These immunotoxins are two functional which crossing the cell membrane and enters the target cell and destroy the cell. Toxin-based treatments are a widespread research field and can have broad applications in the biology and public health. Immunotoxins act selectively against cancer cells and have a good potential for detecting and targeting cancer cells. Specific immunotoxins to target immune cells due to the selection type antibody and antibodies are responsible for the identification of the target cells. Cancer is becoming a major cause of death in most developed countries. In order to have a strong factor in cancer repression, that agent must target the cancer cells directly and specifically. Often, but not always, immunotoxins are produced for disabling and killing cancer cells, that this issue is one of new therapeutic approaches in recently. Clinical aims to designing and create new cancer therapies focused with this approach, a lot of information about the toxin and intracellular pathways have been obtained. So, toxins in medicine are useful for the treatment of human disease and study of professional cellular functions. So, immunotoxins have a high potential for cancer treatment. Other applications of immunotoxins, including immune system regulation and treatment of viral diseases and parasites diseases. More research is needed to improve the immunotoxin effects and to reduce their side effects. On the whole, with design creative, clever and experienced programs, many human diseases, particularly cancers can be in a short period of time and faster than other methods of treatment that the treatment of long, to be treated. Following the design and implementation of clinical trials, the effects of immunotoxins on animal tumorigenic models were performed. In fact, in this study, we focus on the use of protein-bound toxins with bacterial and herbal sources and more specifically Pseudomonas immunotoxins which attached to antibodies to target cancer cells.

Background: Various prediction models have been developed aiming to estimate risk-adjusted mortality, morbidity and length of intensive care unit stay following cardiac surgeries. The European system for cardiac operative risk evaluation II (EuroSCORE II) is a prediction model which maps 18 predictors to a 30-day post-operative risk of death. The objective of this study was to evaluate the performance of the EuroSCORE II risk-analysis predictions among patients who underwent heart surgeries.
Methods: A prospective cross-sectional study was conducted to collect required variables for all consecutive patients underwent heart surgeries in Emam Reza hospital, Mashhad, Iran, from March 2014 to March 2015. Once the patient was hospitalized a cardiologist or a general physician evaluated pre- peri- and post-operative state to fill out the pre-designed structural paper form. Comparing the observed and expected mortality, the sensitivity, specificity, area under the receiver operating characteristic curve (AUC) and finally the discrimination power of the model for our patients were calculated and reported. The model value was calculated using the online tool.
Results: A total of 1337 patients (60% males) were included, the observed mortality rate was 3.2%. Although the overall performance was acceptable, the model showed poor discriminatory power (AUC=0.667, CI 95%: 0.648-0.685) and accuracy with sensitivity=61.88% and specificity=66.23%.
Conclusion: Our single-center study, based on consecutive patients who underwent cardiac surgery showed that EuroSCORE II demonstrated a moderate statistical overall performance with poor discrimination and calibration measures remain as concerning issues regarding 30-day post-operative mortality prediction after adult cardiac surgery. Poor performance measures for this system show the need for reformulating this risk stratification tool aiming to improve post cardiac surgery outcome predictions in Iran.

Background: Association of Addison's disease with connective tissue diseases such as scleroderma and Sjogren have been rarely reported. Anti-centromere antibody (ACA) has been associated with exocrine gland dysfunction in anti-Ro, anti-La negative Sjogren’s syndrome and may be one of the causes of xerostomia in community. The purpose of this article was to introduce a rare case of scleroderma-Sjogren intermediate phenotype with positive anti-centromere antibody in a known case of Addison’s disease admitted for dental caries and xerostomia.
Case Presentation: A 29-year-old woman with Addison’s disease referred to a dental clinic due to recurrent dental caries. Addison’s disease was confirmed by low basal serum cortisol level and unresponsive serum cortisol level to adrenocorticotropin hormone (rapid ACTH stimulation test). Signs of xerostomia, xerophthalmia, Raynaud’s phenomenon, gastro-esophageal reflux, masked face, osteoporosis, positive anti-centromere antibody, negative anti-Ro and anti-La antibodies and failure to match the pathology of the minor salivary gland of lip with Sjogren's disease were found. The diagnosis of scleroderma-Sjogren intermediate phenotype was raised with considering some of the symptoms of scleroderma and Sjogren and not the exact classification criteria for each of these two diseases. Hydroxychloroquine, fluoride and Biotene® mouthwash (Laclede, Inc., CA, USA) (oral moisturizing saliva), chewing gum containing xylitol plus artificial tear droplet was prescribed. Drinking plenty of fluids was recommended. Due to gastroesophageal reflux and osteoporosis, Pantoprazole and CinnoPar® (Cinnagen, Iran) (parathyroid hormone analogue) plus calcium and vitamin D supplements was administered. Regarding adrenal insufficiency, Prednisolone and Fludrocortisone were continued.
Conclusion: For evaluation of recurrent dental caries, especially in patients with autoimmune disease, anti-centromere antibody may be useful to identify the cause of dry mouth, as well as early detection of limited scleroderma or scleroderma-Sjogren intermediate phenotype.

Background: Pseudomonas aeruginosa is an opportunistic pathogen and one of the important factors of hospital infection. It causes many issues such as urinary tract infections, respiratory infection in cystic fibrosis patients, and wound infection in burn patients, septicemia and meningitis. Antibiotic resistance through various mechanisms is one of the challenges for the treatment of pseudomonad-caused infections. According to the inherent and acquired capacity of this bacterium in creating resistance against the antimicrobial factors, it is very important to identify a pattern for its antibiotic resistance. The aim of this study was to deliberate the frequency of pattern antibiotic resistance of pseudomonas aeruginosa strains.
Methods: In this cross-sectional study, 200 pseudomonas aeruginosa isolations (from 86 males and 114 females) were collected from different samples such as urine, blood, wound, catheter and other samples from teaching hospitals in Zahedan City during nine-month period in 2017. After conducting biochemical tests and confirming bacterium type, based on Clinical Laboratory Standards Institute (CLSI), the antibiotic resistance of strains for 10 antibiotics was determined using disk diffusion method. In addition, the minimum inhibitory concentration of three antibiotics such as imipenem, piperacillin/tazobactam and ceftazidime were determined through E-test. The Chi-square test was used for statistical analysis through the SPSS software, version 16 (IBM SPSS, Armonk, NY, USA).
Results: Out of 200 pseudomonas aeruginosa isolations (from 86 males and 114 females), the maximum resistance was related to ciprofloxacin (37%) and gentamicin (28.5%). The minimum resistance was related to piperacillin/tazobactam (6.5%) and ceftazidime (6%). The highest separated strain was from urine sample (54%), blood sample (23.5%) and wound sample (10.5%). Additionally all strains were sensitive to colistin. In this study, the percentage of multidrug-resistance (MDR) and extensively drug-resistant (XDR) strains were investigated, which were 13% and 5.5%, respectively.
Conclusion: In this study, pseudomonas aeruginosa isolates had the lowest resistance to ceftazidime which this antibiotic could be the main treatment option. The high prevalence of MDR strains is a serious warning.

Background: Abnormal placental invasion in pregnancy is one of the most important dilemmas in gynecology and obstetrics medicine and because of the high potential risk of life-threatening massive bleeding, it has been considered as one of the most important causes of maternal morbidity and even mortality. According to the fact that previous cesarean section is the most highlighted and well-known risk factors for developing these types of abnormal placental invasion, and despite comprehensive recommendations for decreeing of this kind of surgery, the rate of caesarian delivery is raising worldwide, detecting the safer methods of management for optimizing the outcome is mandatory.
Case Presentation: In this report, we are discussing a patient in Firoozgar Hospital, Tehran, Iran, with twin pregnancy accompanying with placenta previa with abnormal invasion, which has got the best possible outcome after performing a multidisciplinary approach without any need to blood transfusion or general anesthesia during cesarean hysterectomy as the standard management of placenta increate. In this case, we have performed magnetic resonance imaging (MRI) before surgery. We found out that we can use the exact site of placental margin and the distance between placental margin and uterovesical junction. So we have done the uterine incision horizontally without damaging to the placenta. Generally, Doppler ultrasonography has enough accuracy for detecting all kinds of placenta creates.
Conclusion: By selecting a safe uterine incision, we can prevent such a sudden and massive bleeding during the operation and also avoid occurring end-organ damage due to hemorrhage for instance, acute tubular necrosis, disseminated intravascular coagulation resulted in maternal morbidity and mortality. In this report, we also discuss the points needed for management and treatment of abnormal placental invasion by reviewing the recent literatures.

Background: Acute myeloid leukemia (AML) is a malignant hematological disorder which has numerous manifestations at the initial step such as infections and hemorrhagic signs. This is the first report in which the diagnosis of AML was made after managing of Bartholin gland site swelling and pain as the chief complaint of a patient.
Case presentation: Herein, we present a young girl who was referred to us in our tertiary level hospital, Firoozgar Hospital, Tehran, Iran, in october, 2017 just with pain and swelling of the left Bartholin gland. At first, it was suspected to be a cyst or abscess of Bartholin gland, she did not have any history or symptoms of infection on comprehensive physical examinations such as pneumonia, meningitis, Nevertheless, the ultimate diagnosis of AML was made after generalized and precise systemic examination and laboratory findings were done. According to the guidelines for the treatment of AML, systemic chemotherapy with multiple drugs was given immediately but unfortunately, she died due to severe septicemia which was resistant to broad-spectrum antibiotics and disseminated intravascular coagulation.
Conclusion: Based on our searching, this is the first case. Because we expected other more common symptoms of acute lukemia, systematic and precise generalized examination must be performed gently in all of the patients even in women just with genital symptoms as their chief compliant for instance, pain and swelling of Bartholin gland. Finally, not focusing just on the perineal site and detailed examination for all parts of the body may reveal an accurate diagnosis of the main underlying disease.

Background: Prostate cancer has been reported as a worldwide important kind of cancer and the second most common cause of cancer-related mortality among men. Prostate-specific antigen (PSA) serum level is one of the most important markers of prostate cancer diagnosis. While PSA level helps predict the risk of prostate cancer development, researchers still looking for ways to increase the accuracy of prognostic models. To increase the specificity of PSA and decrease of unnecessary biopsies and morbidity, PSA-related parameters such as PSA doubling time (PSADT) have been used. In this study, the relationship between this factor and the severity of prostate cancer was evaluated.
Methods: In this retrospective study, the data of patients who were subjected to transrectal ultrasound-guided (TRUS) biopsy of the prostate and referred to Imam Khomeini Hospital, Tehran, between 2009 and 2017 were reviewed. We enrolled the men with at least two consecutive elevated PSA level within three months to calculate PSADT. Based on the pathology report, primary and secondary Gleason score (GS) were determined. Correspondingly, considering GS, the patients were divided into two groups with high-grade and low-grade tumor (GS<7 considered as low-grade and GS>7 considered as high-grade tumor).
Results: Totally, 1712 cases of TRUS biopsy of the prostate were studied. Among them, 547 (32.3%) had prostate cancer, of whom 73 cases were eligible based on inclusion criteria and were consented to enroll in the study. According to the data obtained, we found a significant difference in PSADT between the two groups of patients with high-grade and low-grade malignancy (mean±SD PSADT, 9.8±14.2 vs. 16.1±14.9 respectively, P=0.004). Considering the seven months as the cut-off point for PSADT in determining malignancy, there was a significant difference between the two groups according to Fisher's exact test (P=0.01).
Conclusion: In our study, PSADT cut-off of 7 months provided the greatest accuracy for differentiation between low-grade and high-grade malignancy, and PSADT has acceptable accuracy for the diagnosis of high-grade tumors.

Background: Statistical models are used to investigate the relationship between variables in statistical studies. Considering the variety of statistical models, finding the most suitable model is a complex work. This study aimed to compare different models in the treatment of infants' colic and the misspecification of specificity.
Methods: This randomized clinical trial was conducted on 100 infants with colic in the pediatric clinic of Amir Kabir Hospital in Arak, the intervention and control groups were randomly divided into two groups. The collection and analysis of the data was performed in 2016. After teaching massage to mothers of the intervention group, they were asked to perform massage on infants three times a day during the week. In the control group, mothers can relieve the symptoms of colic by shaking the infant. Parents recorded the number and severity of crying daily in the checklist. Finally, by using different models, R software, SAS, and goodness of fit, the best model was introduced.

Background: Examining the course of changes in predictive indicators of future diabetes, such as blood sugar in high-risk individuals including pre-diabetic patients, can provide valuable information about the incidence of diabetes in these individuals. This study aimed to classify people at risk (pre-diabetes) based on the course of changes in their blood sugar and blood lipid and to investigate the incidence of diabetes in these classes on a sample of patients who were referred to the Endocrine and Metabolism Research Center of Isfahan.
Methods: This cohort study was performed based on the information of the Isfahan Diabetes Prevention Plan (IDPs). This project was implemented from April 2004 to March 2018 in the clinics of the Endocrine and Metabolism Research Center of Isfahan. The subjects in this study include 1228 pre-diabetic patients who participated in this project. Demographic and clinical variables of patients including blood sugar and lipid-blood variables were obtained using a questionnaire and laboratory measurements. Also in this study, the number of clinical variables was recorded 3 times. Data analysis was performed using the latent class growth trees model in R software version v4. (R v4.1.0)

Results: The mean (standard deviation) age of participants was 44 (6.86) years. Subjects were classified into two classes of low-risk impaired blood sugar (n=1165) and high-risk impaired blood sugar (n=63) based on the trend of changes in blood sugar levels. Blood sugar levels were reported in the first class (104.28) and the second class (132.41). Conclusion: In the present study, it was concluded that there is a significant relationship between the incidence of diabetes and the different classes formed based on the course of changes in blood sugar of at-risk individuals. Therefore, by classifying people at risk, the incidence of this disease can be predicted and thus prevented. Also,measures such as managing the blood sugar and lifestyle variables of pre-diabetic patients through nutrition counseling classes and regular periodic tests can be used to reduce the incidence of diabetes in the future is used in people with pre-diabetes who are at high risk for the disease.

Background: Early prediction of the outcome situation of COVID-19 patients can decrease mortality risk by assuring efficient resource allocation and treatment planning. This study introduces a very accurate and fast system for the prediction of COVID-19 outcomes using demographic, vital signs, and laboratory blood test data.
Methods: In this analytic study, which is done from May 2020 to June 2021 in Tehran, 41 features of 244 COVID-19 patients were recorded on the first day of admission to the Masih Daneshvari Hospital. These features were categorized into eight different groups, demographic and patient history features, vital signs, and six different groups of laboratory blood tests including complete blood count (CBC), coagulation, kidney, liver, blood gas, and general. In this study, first, the significance of each of the extracted features and then the eight groups of features for prediction of mortality outcomes were considered, separately. Finally, the best combination of different groups of features was assessed. The statistical methods including the area under the receiver operating characteristic curve (AUC-ROC) based on binary Logistic Regression classification algorithm were used for evaluation.

Background: Brain-computer interface systems provide the possibility of communicating with the outside world without using physiological mediators for people with physical disabilities through brain signals. A popular type of BCIs is the motor imagery-based systems and one of the most important parts in the design of these systems is the classification of brain signals into different motor imagery classes in order to transform them into control commands. In this paper, a new method of brain signal classifying based on deep learning methods is presented.
Methods: This cross-sectional study was conducted at Isfahan University of Medical Sciences, School of Advanced Technologies in Medicine, from February 2020 to June 2022. In the pre-processing block, segmentation of brain signals, selection of suitable channels and filtering by Butterworth filter have been done; then data has transformed to the time-frequency domain by three different kinds of mother wavelets including Cmor, Mexicanhat, and Cgaus. In the classification step, two types of convolutional neural networks (one-dimensional and two-dimensional) were applied whereas each one of them was utilized in two different architectures. Finally, the performance of the networks has been investigated by each one of these three types of input data.

Results: Three channels were selected as the best ones for nine subjects. To separate 8-30 Hz, a 5th degree Butterworth filter was used. After finding the optimal parameters in the proposed networks, wavelet transform with Cgauss mother wavelet has the highest percentage in the both proposed architectures. Two-dimensional convolutional neural network has higher convergence speed, higher accuracy and more complexity of calculations. In terms of accuracy, precision, sensitivity and F1-score, two-dimensional convolutional neural network has performed better than one-dimensional convolutional neural network. The accuracy of 92.53%, which is obtained from the second architecture, as the best result, is reported. Conclusion: The results obtained from the proposed network indicate that suitable, and well-designed deep learning networks can be utilized as an accurate tool for data classification in application of motion perception.

Background: chorea-acanthocytosis is a form of the autosomal recessive disease. The onset of disease symptoms usually starts from the third decade of life and presents with chorea, other abnormal movements such as eating dystonia, tongue and lip biting, vocal and motor tics, seizure, and behavioral impairment. In this study, the clinical presentations and brain imaging of these patients were reported.
Methods: In this descriptive study, information about patients with a specific movement disorder who were referred to a tertiary center in the Rasool Akram hospital (Tehran) from March 2018 to February 2019 were recorded. The inclusion criteria were the presence of chorea (a form of abnormal movement) and the presents of acanthocyte cells higher than 10% in a peripheral blood smear. The exclusion criteria were the evidence of secondary causes of the chorea or endocrine disorders. The clinical symptoms and brain imaging findings were evaluated by two expert neurologists and recorded in the patient's electronic files.

Results: Twenty-seven eligible patients were included. 18 patients were male and 9 were female. Sixteen patients had seizures and 90% of them were categorized as generalized tonic-clonic seizures. 21 patients had eating dystonia (71 percent were male and 29 percent were female) and 18 patients had complex motor and vocal tics, 11 patients presented extra ocular movement disorders, and 11 patients had evidence of tongue and lip biting. The absence of the deep tendon reflex was detected in 23 patients. Considering all the patients' movement disorders, the prevalence of eating dystonia was significantly higher in men than in women. (P=0.049). Other abnormal movements were not different between men and female. All patients had caudate atrophy and increased signal intensity in T2/Flair sequences in caudate nuclei and putamen in the brain imaging. Conclusion: The most common abnormal movement after chorea was eating dystonia. The male gender was more susceptible to present eating dystonia than the female. However, this superiority was not seen in other movement disorders.

Methods: This prospective interventional study conducted on patients underwent strabismus surgery in Imam Khomeini Hospital, Ahvaz during May 2021 to March 2022. A total of 38 patients between 8-37 years were included. Patients with previous surgery were excluded. All subjects were evaluated before and three months after successful strabismus surgery. Three months post-surgery the improvement of emotional quotient, self-esteem, body image, social anxiety and social avoidance were evaluated and compared with previous surgery. All data were analyzed by SPSS (V25). P-Value less than 0.05 was considered as significant level. Results: 38 subjects including 18 males (47.4%) and 20 females (52.6%) were included. The mean age of patients was 18.11±9.33 years old. Our results showed that compared with before surgery, significant improvements were noted after surgery, within the emotional quotient subscales including self-awareness (P=0.016), self-regulation (P<0.0001), self-motivation (P<0.0001), empathy (P<0.0001), social skills (P<0.0001) and emotional quotient total score (P<0.0001). Further analysis revealed statistically significant improvements in body image (P<0.0001), social anxiety (P=0.004) and social avoidance (P=0.002). The result showed that the improvement of emotional quotient after strabismus surgery was significantly higher in the age group of less than 12 years (P<0.0001). No significant difference was fund between two  genders for emotional quotient subscales (P>0.05). Conclusion: The results of this study showed a significant improvement in the psychosocial factors including emotional quotient, body image, social anxiety and social avoidance after strabismus surgery. This result suggests that beyond functional and cosmetic improvements, successful strabismus surgery can result in improved emotional quotient and social anxiety, with the greatest effect noted in younger patients.
