Abstract
Background: Non-melanoma skin cancers (NMSCs) are among the most prevalent malignancies globally. Investigating their characteristics and treatment-related outcomes can significantly contribute to optimizing management strategies including surgery, chemotherapy and radiotherapy. This study aimed to examine the characteristics of NMSCs and the complications following surgical treatment (such as necrosis and bleeding).
Methods: This is a retrospective descriptive cross-sectional study which was conducted to investigate the features of patients initially diagnosed with NMSC (confirmed by histopathological examination of the lesion) at dermatology ward of Afzalipour Hospital, Kerman University of Medical Sciences, between 2018 and 2021. Inclusion criteria were definitive diagnosis (based on the result of pathology) of an NMSC and undergoing surgical management. Exclusion criteria included incomplete patient records. Relevant data were extracted and recorded using a data collection form. Finally, all collected information was statistically analyzed according to the study objectives, and the overall frequency of NMSC surgeries, as well as their frequency based on study variables, was reported descriptively.
Results: A total of 37 NMSC surgeries were performed. The majority were basal cell carcinomas located on the face. Over half of the patients were male, and most had underlying medical conditions despite lacking common risk factors such as smoking and sun exposure. The most common flap techniques used were rotational flap, island pedicle flap, and H-plasty flap. Two complications were observed: one case of bleeding at the surgical site and one case of wound edge necrosis, both occurring one week post-operation.
Conclusion: In the southeastern region of Iran, NMSCs requiring surgical treatment showed a lower prevalence than anticipated. However, their pathological and demographic characteristics were consistent with global observations. The incidence of post-surgical complications was also low. Nevertheless, future studies with larger sample sizes in this region and across the country are recommended to enhance the reliability of these findings.

Abstract
Background: Stomach cancer is the fifth most common cancer worldwide. This study aimed to investigate the trend in the incidence of stomach cancer in Shahroud and Meyami districts over a thirteen-year period.
Methods: This study is a cross-sectional study that examines the incidence of stomach cancer using data from the population-based cancer registry system in Shahroud and Meyami Districts in Semnan province over a thirteen-year period from the beginning of April 2010 to the end of March 2022. Age-standardized incidence rates were calculated using both the new and old-World Health Organization standard populations. Trend in cancer incidence were analyzed using Joinpoint regression.
Results: Between 2010 and 2022, a total of 474 new cases of stomach cancer were reported. The mean age at diagnosis was 69.3±12.8 years, with 70.3±12.7 years in men and 67.8±12.8 years in women. The age-standardized incidence rate based on the new WHO population was 15.1 per 100,000 people for the entire period, and 20.9 and 9.5 per 100,000 for men and women, respectively. The annual percentage change indicated a (APC: -4.60 % (95% CI: -0.08 to -9.36)) decrease per year, which was statistically significant (P=0.047), particularly in men (APC= -4.42%, (95% CI: -8.39 to -0.63, P=0.024)), whereas the decline in women was not statistically significant (APC= -4.28%, (95% CI: -10.45 to 1.79, P=0.150)). The incidence of stomach cancer increases with age, with the highest number of cases observed in the 75-79 years age group. The incidence trend in the age group 70-74 years (AAPC: -8.98% (95% CI: -2.75, -14.72 was significantly (P=0.005) decreasing.
Conclusion: The findings of this study showed that the age-standardized incidence rate of stomach cancer had a decreasing trend and that incidence increased with advancing age. Moreover, the incidence rate in men was approximately twice that in women. In men, the incidence trend showed a significant decline, whereas in women no significant change was observed.

Abstract
Background: Adenoid cystic carcinoma (ACC) is a rare neoplasm of the major salivary glands, characterized by a slow-growing tumor, wide local infiltration, perineural spread, a propensity to local recurrence and distant metastasis, and has a poor prognosis. Although surgery and radiotherapy are considered standard treatments, the role of systemic therapy in advanced and metastatic stages remains unclear and rarely results in complete remission. Due to the rarity and limited number of reported cases, here, we report a complete response with systemic treatment in a case of metastatic ACC of the salivary gland.
Case Presentation: The patient is a 50-year-old woman with a history of ACC of the submandibular salivary gland at 20 years old. No recurrence of the disease was observed until, at 47 years old, when metastatic adenocarcinoma with salivary gland origin was diagnosed. From the age of 47 to 50 years, multiple cervical lymph node involvement, multiple masses in the parotid gland and thyroid tissue, as well as distant metastasis to the breast, ovary, and lungs were observed. The patient underwent cervical lymphadenectomy, total parotidectomy, and several courses of radiotherapy and chemotherapy. After six cycles of the Bevacizumab + Adriamycin + Cisplatin regimen, radiologic evaluation confirmed a complete response to the treatment with the disappearance of pulmonary nodules and parotid lesions. The patient is currently under follow-up.
Conclusion: Our reported case shows the aggressive nature of recurrent metastatic ACC of the salivary gland and the positive effect and importance of systemic treatment in these patients. Because the metastasis can appear very slowly, early diagnosis is essential for a better prognosis. These rare malignant lesions should be followed up for a long time after initial treatment due to slow growth, frequent recurrence and late and distant metastasis possibility. This case highlights the potential of systemic therapy to induce complete response even in extensively metastatic disease, suggesting that further clinical trials may be warranted.

Abstract
Background: The use of mesh is considered one of the most effective methods and is considered the method of choice in hernia repair. However, the debate about the choice of mesh type still persists. Therefore, in the present study, the results of using ultra-light Prolene mesh with standard Prolene mesh in hernia repair surgery were compared.
Methods: The present study is a double-blind, randomized, controlled clinical trial that was conducted at Shahid Mohammadi Hospital in Bandar Abbas. Demographic information including age, sex, height, and weight were recorded in a checklist. Patients were randomly assigned to two groups. Each group used Prolene mesh in the first group and ultra-light Prolene mesh in the second group for repair. Hernia repair was performed by the surgeon using the Lebakhstein method.
Results: 119 patients were included in the study. 70 patients (57.4%) had direct hernia and 52 patients (42.6%) had indirect hernia. The mean age of the Prolene group was 43.8±7.49 and the ultra-light Prolene group was 44.32±8.91 years (P=.713). The mean BMI in the Prolene group was 29.94±3.43 and in the ultra-light Parwan group was 29.66±3.76 (P=.673). Wound infection was not observed in either group. Chronic pain was 14.5 in the Prolene group and 10.3 in the ultra-light Prolene group (P=.490). Administrative retention was 6.3 in the Prolene group and 8.5 in the ultra-light Prolene group (P=.738). The recurrence rate 3 months after surgery was 0 in the Prolene group and 1 case (1.7%) in the ultra-light Prolene group (P=.487). The recurrence rate 12 months after surgery was 2 cases (3.2%) in the Prolene group and 3 cases (5.2%) in the ultralight Prolene group (P=. 672). The time to complete recovery was 6.94±1.63 days in the Prolene group and 6.68±1.64 days in the ultralight Prolene group (P=. 368). There was no significant difference in pain intensity at 2, 6, and 24 hours after surgery between the two study groups.
Conclusion: Both Prolene and ultralight Prolene mesh have relatively similar efficacy in inguinal hernia repair. Although the advantages of ultralight Prolene mesh, such as pain intensity, chronic pain, and faster onset of motion, were slightly different in the ultralight Prolene group, the recurrence rate was slightly higher in the ultralight Prolene group.

Abstract
Background: Trichomonas vaginalis is one of the main causes of vaginitis and cervical inflammation worldwide. Almost half of sexually transmitted and curable diseases worldwide can be assessed through the examination of this disease, so the aim of this study is to determine the prevalence of trichomoniasis in Iranian women.
Methods: This study is a review of the SID, PubMed, Science Direct, and Google Scholar databases, conducted up to September 2023. The extracted data were analyzed using CMA software (version 2). A search of articles in Science Direct, SID, PubMed, and Google Scholar databases was conducted in accordance with the PRISMA statement criteria, including systematic search, screening of articles, and selection of appropriate studies. The words used for the search and final review in this systematic review were determined based on MESH Terms in the PubMed database. These keywords that were used and selected in this study were in English and Persian. The final information obtained from the studies was reviewed and analyzed using the Comprehensive Meta-analysis (CMA, Version 2) software, and finally the heterogeneity of the studies was examined with the I2 test.
Results: Based on the search for studies and their screening, 22 studies were finally included in the meta-analysis. This study included a sample size of 49,990 Iranian women who were included in the study. In the heterogeneity analysis based on the studies obtained, the heterogeneity was 99.7. Due to the heterogeneity of the studies, the random effects method was used for the final analysis. The prevalence of Trichomonas vaginalis in Iranian women was reported to be 9.3 (95% CI: 4.6-18) based on the 22 final studies and meta-analysis. The publication bias analysis indicated the absence of bias in the studies (p: 0.175).
Conclusion: Based on the prevalence report in the meta-analysis, a relatively high prevalence was reported in Iranian women, and this situation requires more awareness raising through health centers to families, as well as care and screening of women in these centers and also in obstetric centers.

Abstract
Background: In this study, Botox method is compared with sleeve gastrectomy as one of the endoscopic methods in the treatment of obesity for patients who are not effective in lifestyle and drug modification methods and do not have the interest or necessary conditions for bariatric surgery.
Methods: This Cross-sectional study was conducted in eligible patients who were outpatients at the gastroenterology clinics of Amir al-Momenin Hospital, Arak, in June 2014 for one year in the gastroenterology clinic after obtaining informed consent, demographic information, and anthropometric measurements. After 12 weeks, patients in both groups were visited again. In patients in group A (Botox group), endoscopy was performed by an experienced gastroenterologist under sedation after a 10-hour fast, and in patients in group B (sleeve gastrectomy) under general anesthesia, a partial and longitudinal gastrectomy was performed. The BAROS questionnaire was used to assess the quality of life of patients.
Results: The mean age of the subjects in the endoscopic botulinum neurotoxin group was 30.88±11.89 years and the sleeve gastrectomy group was 29.88±11.06 years. In this study, 12 subjects (24.0%) were male and 38 subjects (76%) were female. There was a significant difference in the mean body mass index and weight at four measurements in the two study groups (endoscopic botulinum neurotoxin and sleeve gastrectomy). There was no statistically significant difference in the mean blood pressure, laboratory results, and mean quality of life in the study groups.
Conclusion: Endoscopic botulinum injection in the stomach is an effective and safe method for short-term weight loss, but its long-term effect on weight and the occurrence of complications or metabolic effects requires long-term follow-up.

Abstract
Background: Spinal anesthesia is an effective method for providing analgesia in surgery and a safe alternative to general analgesia; But despite its benefits, in many cases it is not free of side effects, including unwanted cardiovascular events such as hypotension and bradycardia. Ondansetron effectively reduces the incidence of nausea, vomiting, and bradycardia associated with spinal anesthesia Thus, the present study aimed to assess intravenous ondansetron's efficacy in preventing post-spinal hypotension among patients scheduled for lower extremity orthopedic surgery at Peymanieh Hospital in Jahrom, Iran.
Methods: This randomized double-blind clinical trial included 60 patients undergoing lower limb orthopedic surgery at Peymanieh Hospital, Jahrom, Iran, from March 2021 to February 2022. Patients were randomly allocated into two groups: the intervention group (receiving 8 mg intravenous ondansetron) and the control group (receiving distilled water). Systolic and diastolic blood pressure (SBP, DBP) and heart rate (HR) were measured before pre-spinal anesthesia, after spinal anesthesia and then every two minutes for the first ten minutes and at 15, 30, 45, 60 and 90 minutes after surgery. After spinal anesthesia, the patient was asked about pruritus every 10 minutes. Nausea and vomiting during surgery in case of incidence, recording and nausea after spinal anesthesia, the patient was asked every 10 minutes.
Results: The chi-square test indicated no significant differences between the study groups regarding age and sex distribution(P>0.05). Time before anesthesia, immediately after anesthesia, 10 minutes, 15 minutes, 30 minutes, 45 minutes, 60 minutes, 75 minutes, and 90 minutes after anesthesia, significant difference between ondansetron and placebo groups from There was no mean SBP and DBP and HR (P <0.05). No significant difference between ondansetron and placebo groups in the incidence of pruritus and nausea and vomiting at different times (p <0.05).
Conclusion: Dose of 8 mg of ondansetron in lower limb orthopedic surgery has no significant effect on hemodynamic symptoms as well as the prevention of postoperative nausea, vomiting and pruritus in these patients. Therefore, to achieve more results regarding the transient effect of this drug, it can be compared with other drugs in the class of HT3-5 receptor antagonists.

Abstract
Background: Although osteosarcoma in the head and neck region is relatively rare accounting for 2.1% of all malignant oral and maxillofacial tumors it is nevertheless regarded as the most common primary malignant bone tumor in children and young adults. In the craniofacial skeleton its overall occurrence remains uncommon, and that rarity contributes to diagnostic difficulty and occasional delay. The neoplasm is recognized simultaneously for its infrequency and its malignant character, and these features together can obscure recognition when early symptoms are muted or resemble more benign oral conditions. Because presentations may be subtle, careful clinical attention to patient-reported sensations and visible mucosal or submucosal changes is advisable. Early complaints may initially involve tingling paresthesia or awareness of a focal oral mass. Vigilance matters in everyday oral and maxillofacial practice.
Case Presentation: The patient was a 38-year-old married man from Asadabad County, Hamedan Province, who presented to the Department of Oral and Maxillofacial Diseases at the School of Dentistry, Hamedan, during February March 2025. He reported a tingling, electric-shock like sensation together with a lesion on the floor of the mouth. The persistence of the sensation and the presence of a visible lesion prompted evaluation in a specialized academic clinic. The demographic context, the anatomic location in the floor of the mouth, and the clear time frame are central features of the presentation. The chief complaint centered on the peculiar sensation and the discernible lesion, which together motivated clinical assessment in an oral and maxillofacial setting.
Conclusion: This report highlights the importance of considering mandibular osteosarcoma in the differential diagnosis of peripheral tumoral lesions. Reporting such cases can improve understanding of unusual clinical presentations and assist in more accurate clinical decision-making. The central message is unchanged: clinicians should include mandibular osteosarcoma among diagnostic possibilities when encountering peripheral lesions so that evaluation proceeds thoughtfully.

Abstract
Background: Neonatal circumcision is one of the most common surgical procedures worldwide, performed for cultural, religious, and health-related reasons. The two primary methods for neonatal circumcision are the classic surgical method (using sutures or clamps such as Gomco or Mogen) and the plastic ring method (e.g., Plastibell). This systematic review and meta-analysis aimed to compare the benefits and complications of these two methods in neonates.
Methods: A systematic search was conducted in PubMed, Scopus, Web of Science, and Google Scholar databases for articles published between 2000 and 2024. Inclusion and exclusion criteria: Included studies included randomized controlled trials (RCTs), cohort studies, and cross-sectional studies that compared the benefits and harms of classical surgery and plastic ring in infants (<28 days). Studies without a comparison group, studies conducted in older children or adults, and articles that did not provide sufficient data were excluded. Keywords included "neonatal circumcision", "plastic ring", "Plastibell", "classical surgery", "Gomco clamp", "Mogen clamp", "benefits", "complications" and their English equivalents.
Studies comparing the benefits and complications of the classic surgical method and the plastic ring method in neonates were included. Data were meta-analyzed using a random-effects model, and risk ratios (RR) with 95% confidence intervals (CI) were calculated.
Results: From a total of 12 included studies (involving 5,342 neonates), the plastic ring method was associated with a significant reduction in bleeding (RR: 0.45; 95% CI: 0.32-0.64) and healing time (mean difference: -2.3 days; 95% CI: -3.1 to -1.5) compared to the classic surgical method. However, the risk of skin adhesion was higher with the plastic ring method (RR: 1.32; 95% CI: 1.05-1.66). Serious complications, such as urethral injury, were rare in both methods (less than 0.2%).
Conclusion: The plastic ring method is a suitable option for neonatal circumcision due to its ease of use, reduced bleeding, and faster healing time. However, careful post-procedural care is essential to minimize the risk of skin adhesion. The choice of method should consider the operator’s expertise and parental preferences.

Abstract
Background: Breast cancer is the most prevalent malignancy among women and remains a leading cause of cancer-related mortality worldwide. Early detection can markedly improve patient survival, yet existing screening methods often lack sufficient accuracy and sensitivity. lncRNA KCNQ1OT1 has been implicated in the initiation and progression of tumors in several cancers, including breast cancer. This study aimed to evaluate the diagnostic potential of serum lncRNA KCNQ1OT1 expression as a biomarker for early detection of breast cancer.
Methods: This case-control study was conducted at Ahvaz Jundishapur University of Medical Sciences, Shafa Hospital, Ahvaz, Iran, between September 2024 and March 2025. Serum samples were obtained from 30 patients with histologically confirmed breast cancer and 30 healthy women serving as controls. Total RNA was extracted from 500 µL of serum, and cDNA was synthesized using oligo (dT) primers. Real-Time PCR was performed in triplicate, with GAPDH as the internal control. Relative gene expression was calculated using the 2^-ΔΔCt method, and data were analyzed using the Mann-Whitney U test and ROC analysis.
Results: The patient and control groups were homogeneous for most demographic parameters, but showed significant differences in age (P=0.023) and ethnicity (P=0.004). Most patients were in stage I of the disease. The median expression of serum KCNQ1OT1 was significantly lower in patients (0.024, IQR 0.013-0.033) than in controls (0.039, IQR 0.027-0.051), indicating marked downregulation in the patient group (P=0.0003). The ROC analysis yielded an AUC of 0.82 (95% CI: 0.67-0.96, SE=0.07, P=0.0005). At an optimal cutoff value of >0.031, the sensitivity was 70%, the specificity was 95%, and the positive likelihood ratio (LR⁺) ≈ was approximately 14, demonstrating strong discriminative ability.
Conclusion: Serum KCNQ1OT1 exhibits promising diagnostic performance for identifying early-stage breast cancer and may serve as a reliable noninvasive biomarker. Larger multicenter studies incorporating molecular subtyping and tissue correlation are required to validate its clinical applicability and strengthen diagnostic accuracy.

Abstract
Background: Postoperative pain is a significant concern after cholecystectomy. Given the role of vitamin D in pain management, this study investigated the correlation between preoperative vitamin D levels and postoperative pain severity in patients undergoing laparoscopic cholecystectomy, with the aim of improving pain management and enhancing postoperative care.
Methods: This prospective observational study (January 2024- February 2025) was conducted on 87 patients undergoing laparoscopic cholecystectomy at Imam Ali Hospital of Bojnurd. Inclusion criteria were age 18-45, non-urgent laparoscopic cholecystectomy, and good physical status. Exclusion criteria were chronic pain, regular analgesic use, known psychiatric or neurological disease or treatment, substance abuse, emergency cholecystectomy, or conversion to open surgery. Participants fasted for 12 hours preoperatively. All received 1 g (IV) ceftriaxone one hour before and 12 hours after surgery. Anesthesia was induced with propofol and fentanyl and maintained with isoflurane, nitrous oxide, or oxygen. Anesthesia and surgical technique were standardized, with any deviations recorded. We collected demographic data and extracted perioperative details from records and interviews. Pre-induction venous blood samples were collected, processed, and stored at -20°C. Serum vitamin D concentrations were quantified via ELISA method, and participants were subsequently stratified into two groups based on these measurements. Postoperative pain was assessed on a Visual Analog Scale (0-10) at 6, 12, 18, and 24 hours. Analgesic regimens followed standard protocol under physician supervision and were unaffected by the study.
Results: Lower serum vitamin D levels were associated with higher postoperative pain scores (P<0.01), with this relationship being significant at 6, 12, and 18 hours postoperatively (P<0.01, P<0.01, and P<0.05, respectively). Insufficient vitamin D levels and female gender were also independent risk factors for acute pain after laparoscopic cholecystectomy (P<0.01).
Conclusion: Based on the results of the present study, preoperative vitamin D deficiency is associated with increased postoperative acute pain scores in patients undergoing laparoscopic cholecystectomy, especially in women. These findings may be useful for postoperative pain management in patients with vitamin D deficiency.

Abstract
Background: This study investigates the use of color filters, which represent a scientific and standardized approach to assist individuals with visual impairment. Although there is no fixed protocol for prescribing color filters, these filters, which are often prescribed by ocular care providers in a trial-and-error manner today, help improve visual performance, control glare, and enhance motor skills in affected individuals. Given the absence of formal guidelines and standardized protocols in this area, this study tested common diseases leading to visual impairment against various color filters.
Methods: The study population consisted of patients visiting the Optometry Clinic of Labbafi Nejad Hospital. Participants were voluntarily referred from retinal and corneal departments to this clinic. This quasi-experimental study evaluated acuity at distance and near and contrast sensitivity function with and without color filters, and compared the results. After analysis, filter(s) suitable for each participant were identified and applied clinically, with one-month monitoring and re-evaluation.
Results: A total of 99 participants (54 male, 45 female) with a mean age of 32.19±15.41 years were included. The results showed that after using color filters, distance visual acuity (BCVA) improved significantly in most diseases (P<0.001). However, in albinism and diabetic retinopathy patients, there was no significant improvement in distance vision. At near distance, there was generally a significant improvement in near vision in most diseases after applying the filters (P=0.001). Exceptions included albinism and glaucoma, where no significant difference was observed (P=0.073). For contrast sensitivity (CSF), most patients showed improvement and increased contrast sensitivity (P<0.001), but this increase was not significant in albinism and glaucoma (P=0.483).
Conclusion: The study suggests that the use of certain color filters in visually impaired patients leads to significant improvements in both distance and near acuity and contrast sensitivity function, potentially enhancing quality of life. Based on the quantitative results, selecting the appropriate filter should be disease-specific and done with greater precision. However, the diversity and severity of diseases, the degree of vision loss, and genetic differences among individuals require greater attention to practical experiences and statements from this patient group. Additionally, patients with more than one ocular condition often changed the type and color of the filter.

Abstract
Background: Patients undergoing mechanical ventilation in the intensive care unit (ICU) are at higher risk for delirium. The present study aimed to compare the frequency of delirium in patients requiring anesthesia receiving the Presedex and fentanyl regimen with the midazolam and fentanyl regimen in the intensive care unit (ICU).
Methods: This historical cohort study was conducted on all patients hospitalized in the intensive care unit of Kowsar Hospital in sanandaj from May 2018 to December 2024 as a census with a sample size of 40 people in each group. Delirium and restlessness were assessed based on RASS criteria and the GCS scale was used to assess the level of consciousness of the patients. The data were entered into SPSS 24 software and a significance level of less than 5% was considered.
Results: The average age of the patients in Perdex, fentanyl, midazolam, and fentanyl regimens was 41.52 and 34.05 years, respectively. 53(66.3%) patients were male and the rest were female. The GCS score in the Presdex and Fentanyl group was 14(35%) and the Midazolam and Fentanyl group was 4(10%) with a level of consciousness above 7. The RASS score (5 patients in the Presdex and fentanyl group (12.5%) and the midazolam and fentanyl group (36 patients in the midazolam and fentanyl group (90%) had an anxiety score of zero or higher) was 0. The frequency of delirium based on CAM-ICU criteria in the Presdex and fentanyl group was 27(67.5%) mild delirium and 13(32.5%) moderate delirium, but in the midazolam and fentanyl group, 6(15%) mild delirium, 24(60%) moderate delirium, and 10(25%) severe delirium were present, and this difference was significant in the results of level of consciousness and restlessness and incidence of delirium (P=0.000).
Conclusion: The results showed that the use of Presedex and fentanyl would be more effective in reducing the incidence of delirium, and the use of this drug could be effective.

Abstract
Background: Seizures are common neurological disorders in childhood, with a prevalence of 4 to 6 cases per 1,000 children in the community. This study was conducted to evaluate the prognosis of the first non-provoked seizure in terms of recurrence.
Methods: In this descriptive-analytical study, the records of all patients hospitalized with a diagnosis of seizure without a trigger for the first time at Imam Khomeini Hospital in Ilam from April 2016 to March 2019 were reviewed retrospectively. Information was extracted from the patients' records. All records were reviewed in terms of seizure type characteristics.
Results: The results of imaging with seizure recurrence in these patients showed that there was a significant relationship between the result of the first imaging and the report of seizure recurrence (P≥0.001 and Phi-Cramers=0.729). Since EEG of all patients was not recorded, they were excluded from the study. There was also a significant relationship between drug treatment and seizure recurrence at a significance level of 5% (P=0.004 and Phi-Cramers=0.273). This study showed that among the 64 patients who had started drug treatment, 44 reported no seizure recurrence and 20 reported seizure recurrence, and among the 54 patients who had not received drug treatment, 23 reported no seizure recurrence and 31 reported seizure recurrence. In the first year, the highest frequency of seizure recurrence was in the first 6 months. With increasing time after seizure, the rate of seizure recurrence decreased. The highest percentage of seizures without a triggering factor was in the age group of 5-10 years and the lowest percentage was in the age group under 5 years.
Conclusion: Identifying key factors associated with seizure recurrence will enable healthcare professionals to tailor their diagnostic and therapeutic approaches, ultimately enhancing patient care and safety. By understanding the importance of family history, seizure characteristics, and neuroimaging findings, clinicians can make informed decisions that may prevent life-threatening complications and minimize cognitive impairment in affected children.

Abstract
Background: Although abdominoplasty is cosmetically effective in patients with obesity or a history of significant weight loss, it can lead to serious complications. This case report highlights the role of elevated intra-abdominal pressure and delayed diagnosis of Abdominal compartment syndrome (ACS) in the development of multiorgan failure and patient mortality.
Case Presentation: A 49-year-old female patient with a history of appendectomy and hysterectomy in the past years was admitted to the hospital for cosmetic abdominoplasty. She had a history of hypothyroidism and was taking levothyroxine regularly. Occasional tobacco use was also mentioned in the patient's history. During the operation, in addition to abdominoplasty, liposuction and flank surgery were also performed. The patient was initially placed in the supine position and then in the prone position for the last two hours. During recovery, the patient complained of shortness of breath and developed tachycardia. Despite persistently elevated BUN and creatinine, and progressive acidosis, a surgical consultation was performed with suspicion of Abdominal compartment syndrome (ACS), but this diagnosis was rejected by the surgeon. Also, despite clinical suspicion of Abdominal compartment syndrome (ACS) by the anesthesia team, in the early stages, the surgeon responsible for the patient did not have sufficient clinical suspicion of this complication and accordingly, intra-abdominal pressure measurement via bladder catheter was not performed. Since monitoring intra-abdominal pressure via bladder catheter requires a specific technique and coordination between anesthesia, surgery, and critical care teams, and since the possibility of ACS had been ruled out by the surgeon at that time, this procedure was not performed. Ultimately, the patient was transferred to the dialysis unit, but during hemodialysis, he suffered respiratory arrest and, after tracheal intubation, subsequently suffered cardiac arrest. Unfortunately, despite cardiopulmonary resuscitation efforts, the patient died.
Conclusion: Although rare, abdominal compartment syndrome should be considered a critical differential diagnosis in high-risk patients following prolonged surgeries such as abdominoplasty with extensive plication. Monitoring intra-abdominal pressure and early intervention upon symptom onset may prevent fatal outcomes.

Abstract
Background: To improve hemostasis and optimize the healing process, autologous fibrin sealant (FS) has been introduced in selected cases. However, the clinical benefits of FS in sinonasal surgery remain controversial and require further evaluation. This study aimed to investigate the effects of autologous FS on hemostasis, mucosal healing, postoperative clinical outcomes, and recurrence in patients undergoing bilateral FESS, compared with normal saline as the control.
Methods: This randomized clinical trial included 32 patients who underwent bilateral FESS at Ghaem and Imam Reza University Hospitals in Mashhad, Iran, between 2019 and 2021. For each patient, autologous FS was applied to one nasal cavity, while the contralateral cavity received normal saline. Postoperative outcomes including bleeding, crusting, adhesion formation, and infection were assessed at 1 week, 1 month, and 3 months after surgery. In addition, sinonasal symptom burden and endoscopic findings were evaluated using the Sinonasal Outcome Test (SNOT-22) and the Lund-Kennedy endoscopic score, respectively, both recorded preoperatively and three months postoperatively.
Results: Application of autologous FS significantly reduced immediate postoperative bleeding, and no further bleeding events were noted during follow-up. Pain severity was comparable between the two sides. No statistically significant differences were observed in crust formation, adhesion, infection, recurrence, or changes in Lund-Kennedy scores between the FS and control sides (p=0.08, p=0.8, p=0.17, and p=0.14, respectively).
Conclusion: Autologous fibrin sealant reduced early postoperative bleeding without adversely affecting pain control, mucosal healing, or recurrence after FESS. Larger randomized trials with extended follow-up are recommended to determine its definitive clinical value and potential for routine use in surgical practice.

Abstract
Background: Shortness of breath is a common disorder and means difficulty in breathing and shortness and shallow breathing that the patient feels unpleasant, difficulty and shallow breathing. The main purpose of this study was to analyze patients undergoing pulmonary angiography with a prognosis of pulmonary embolism in the emergency department.
Methods: This descriptive-analytical study was performed in the adult emergency department of Shahid Mostafa Hospital in Ilam in March2018-March2020 after receiving permission from the ethics committee. This study evaluated patients over 18 years of age who underwent CTPA with a pre-diagnosis of PE.
Results: The highest frequency was reported in CT findings of 31.9% normal, 27.6% PE. In our study based on CT results, 30.2% of patients suffered from PE. The highest frequency was reported in CT findings of 31.9% normal, 27.6% PE. In the present study, 65.5% of patients presented with shortness of breath, of which CT results showed 28.9% (PE), 38.2% (Non PE) and 98% (Normal). Other complaints of patients with shortness of breath were reported with CP (7.8%), lower edema (6%), respiratory distress (8.6%), CP and fever (5.2%) and hemotypy (1.7%).
Conclusion: Based on the above study, we conclude that the criterion for selecting patients for CT angiography to rule out PTE is the most important criterion for clinical examination and the Welsh Criteria score. As we can see, the results showed that patients with a Wales score above 8-12 had 80% PTE and patients with a Wales score of 3-6 had 23.5% PTE and the rest had a negative answer, so the Wells criteria were good criteria which unfortunately Due to some conditions, the diagnosis of a general practitioner or carelessness in examinations are not taken into account and causes a large percentage of patients with complaints of shortness of breath to undergo CT angiography while not having the necessary criteria based on Wells scores and clinical examination. CT angiography is either normal or another condition that does not require CT angiography and radiation.

Abstract
Background: Helicobacter pylori (H. pylori) is a human gastrointestinal pathogen that infects more than half of the world's population and leads to chronic gastritis and its role in the development of gastric ulcers, gastric cancer and gastric lymphomas is considered. However, eradication of this bacterium with triple therapy fails in more than 30% of cases. Therefore, efforts to find new treatment methods are increasing. As a result, this study was conducted to evaluate the effectiveness and tolerability of several drug regimens compared to the standard regimen.
Methods: This study is a randomized clinical trial in which patients with Helicobacter pylori infection were randomly selected in the endoscopy department of Amiralmomenin Hospital and the Gastroenterology Clinic of Professor Ghavamzadeh Clinic, Arak from October 2024 to March 2025 and were divided into three groups, including a control group and two intervention groups, with three different drug regimens. Four weeks after treatment, the rate of bacterial eradication in all three evaluation groups was assessed using fecal antigen testing and the treatment results were compared using appropriate statistical analyses.
Results: The frequency of negative test results in intervention group 2 was higher than in control and intervention group 1. (P<0.001) and the rate of Helicobacter pylori eradication was in intervention group 2 (94%), in control group (54%), and in intervention group 1 (20%). The chance of H.P eradication in intervention group 1 decreased by 84% compared to the control group and increased by 10.77 times in intervention group 2 compared to the control group. Also, a significant proportion of H.P eradication success was observed in people without diabetes (p-value = 0.022, Phi = -0.188, n = 150) and the rate of drug side effects was higher in intervention group 2 compared to the other two groups.
Conclusion: This study showed that compared to the standard regimen, a 2-week regimen of amoxicillin, omeprazole, and clarithromycin plus bismuth is a good, potent, and more cost-effective regimen for eradicating Helicobacter pylori.

Abstract
Background: Retinal photoreceptor degeneration is a major cause of blindness. Stem cell therapies offer promise, and the miR-183/96/182 cluster, particularly miR-182 and miR-183, plays a crucial role in photoreceptor development and survival. Targeting these miRNAs may enhance human bone marrow–derived mesenchymal stem cells) hBMSCs (differentiation into photoreceptor-like cells, improving their therapeutic potential.
Methods: This in vitro study was conducted from April 2019 to March 2021 at the Clinical Biochemistry Research Center, Shahrekord University of Medical Sciences. hBMSCs were cultured in DMEM with fetal bovine serum and transfected with miR-182 and miR-183 mimics using Lipofectamine, with a scramble miRNA control. Transfection efficiency and miRNA overexpression were evaluated at 24 and 48 hours using real-time PCR. miRNA expression was normalised to Snord, while mRNA levels were normalised to GAPDH using the 2−ΔΔCt method. Photoreceptor-like differentiation was assessed by measuring the expression of retina-specific transcription factors and markers (OTX2, CRX, NRL, SLC1A1, PKCα, Recoverin, and RHO). Statistical analyses included the Shapiro–Wilk test for normality and the Mann-Whitney U test for group comparisons. Data were reported as Mean ± SEM, with 95% confidence intervals, and significance set at α = 0.05.
Results: Transfection of miR-182 and miR-183 significantly increased miRNA levels at 24–48 hours (P < 0.001) compared to the scramble control. This led to a marked upregulation of retinal-related genes, including CRX, OTX2, PKCα, Recoverin, NRL, and RHO, indicating activation of the photoreceptor gene network. Time-resolved analysis revealed stronger effects at 24–48 hours, supporting a transient window for pro-differentiation. RHO and CRX exhibited the most significant increases, while OTX2 and PKCα showed parallel rises, suggesting coordinated activation of early and intermediate photoreceptor programs. Scramble controls did not show comparable changes.
Conclusion: Transient overexpression of miR-182 and miR-183 in hBMSCs activates a photoreceptor-like gene expression program, promoting differentiation toward photoreceptor-like cells. This finding supports the potential use of miR-182/183 in stem cell-based therapies for retinal degeneration. Further studies should confirm protein expression, functional outcomes, and in vivo efficacy.
