Abstract
Background: Primary nocturnal enuresis (PNE) is a common and distressing childhood disorder characterized by involuntary urination during sleep after the age when bladder control is normally achieved. It affects not only the child’s quality of life but also family dynamics and social relationships. Previous studies have suggested a possible link between PNE and psychological or behavioral problems, yet findings have been inconsistent across populations. The present study aimed to investigate and compare the prevalence and patterns of psychiatric disorders among children with primary nocturnal enuresis and healthy controls in Sanandaj, Iran.
Methods: This case-control study was conducted in Sanandaj from October 2024 to April 2025. The study population included children referred to the Medical, Educational, and Therapeutic Center of Kurdistan University of Medical Sciences. A total of 228 participants were enrolled, comprising 108 children diagnosed with primary nocturnal enuresis and 120 age- and sex-matched healthy controls selected through convenient sampling. Psychiatric assessments were performed using the parent version of the Child Symptom Inventory-4 (CSI-4) questionnaire, which evaluates a wide range of childhood behavioral and emotional disorders based on DSM-IV criteria. Statistical analysis was performed using Stata version 18, and comparisons between groups were made using the chi-square and Fisher’s exact tests. A p-value < 0.05 was considered statistically significant.
Results: Children with primary nocturnal enuresis had significantly higher frequencies of attention deficit disorder (ADD), hyperactivity disorder (HD), attention deficit-hyperactivity disorder (ADHD), oppositional defiant disorder (ODD), generalized anxiety disorder (GAD), and tic disorder compared with the control group (p < 0.05). In contrast, the prevalence of phobia and obsessive-compulsive disorder (OCD) was slightly higher in the control group. No statistically significant difference was found regarding post-traumatic stress disorder (PTSD) between the two groups.
Conclusion: The findings suggest that primary nocturnal enuresis may serve as an indicator of increased vulnerability to certain psychiatric disorders in childhood. Early recognition and psychological evaluation of children with enuresis are recommended to improve long-term outcomes and mental well-being.

Abstract
Helicobacter pylori is one of the most common chronic bacterial infections worldwide, with acquisition often occurring in childhood. While its role in the pathology of gastroduodenal diseases in adults is well-established, its impact on the pediatric population presents a unique set of clinical and pathophysiological challenges. This comprehensive review examines the complex and bidirectional relationship between Helicobacter pylori infection and host iron metabolism in pediatric and infant populations. For this review, the PubMed database was utilized for studies published from April 1979 through December 2024. Studies based on English language were included using the MESH terms "Helicobacter pylori," "iron," and "ferritin." According to the inclusion criteria, studies related to H. pylori infection and iron condition in patients under 18 years old were selected. Articles such as review articles, case reports, letters to the editor, and animal or in vitro studies were excluded. The main aim of this study was to illuminate the critical role of iron as an essential micronutrient and factor for both the host and the pathogen, examining the multifaceted mechanisms involved in H. pylori-induced iron homeostasis disruption in children.
|
The findings indicate a multifaceted relationship: virulent Helicobacter pylori strains are significantly and inversely associated with true body iron stores, leading to Iron deficiency anemia (IDA). However, chronic inflammatory states can paradoxically elevate ferritin levels, masking underlying iron deficiency. Complex interaction between bacterial infection, host inflammatory responses, and iron deficiency is an important factor influencing both the severity of the damage caused by this bacterial infection and its chronicity in the pediatric population. Identification and comprehensive understanding of these complex mechanisms is of great importance for the effective management of iron deficiency anemia in children with H. pylori infection. Considering, increase in the incidence of H. pylori infection in childhood, it is essential that H. pylori infection be evaluation in children with unknown reasons IDA. Finally, screening methods for H. pylori infection in children is recommended, as this could improve long-term health outcomes.

Abstract
Background: Maternal substance abuse during pregnancy is a significant global public health concern, affecting approximately 10% of pregnant women worldwide and leading to serious adverse outcomes for both mother and fetus. Given Iran’s geographical location and its role as a transit route for narcotics, the prevalence of substance abuse, particularly opium and its derivatives, is notably higher than in many other countries. This systematic review and meta-analysis aimed to determine the prevalence of substance abuse and the most commonly used substances (including opium, heroin, crystal methamphetamine, methadone, amphetamines, and cigarettes) among pregnant Iranian women from 2000 to 2024.
Methods: A systematic search was conducted across PubMed, Scopus, Web of Science, SID, and Iranmedex for articles published between January 2000 and January 2024. Studies investigating the prevalence of substance abuse in pregnant Iranian women were included. Case studies, reviews, letters to the editor, and studies without quantitative data were excluded. Two researchers independently extracted data. Extracted information included: author name, year of publication, province/city, sample size, mean age of participants, type of substance used, and incidence or prevalence rate. Data were analyzed using a random-effects model, and heterogeneity was assessed using the I2 index.
Results: Out of 127 identified articles, 22 were included in the meta-analysis. The overall estimated prevalence of substance abuse among pregnant Iranian women was 3.3% (CI 95%: 2.4-4.5), with high heterogeneity (I2=83%). The most prevalent substances were opium (1.7%), cigarettes (1.3%), methadone (0.5%), heroin (0.3%), crystal methamphetamine (0.2%), amphetamines/methamphetamines (0.1%), cannabis (0.4%), and alcohol (0.2%). Polydrug use was reported at 0.7%. A rising trend in substance abuse prevalence was observed, increasing from 2.1% in 2000-2009 to 3.8% in 2015-2024. A temporal trend analysis of the incidence of substance abuse showed that the incidence of substance abuse in Iranian pregnant women increased from 2.1% in 2000-2009 to 3.8% in 2015-2024. Sensitivity and publication bias analyses showed that the exclusion of low-quality studies did not significantly affect the results. The funnel plot indicated a low probability of publication bias.
Conclusion: Substance abuse among pregnant Iranian women remains a serious challenge, necessitating broader preventive and therapeutic interventions.
Keywords: neonatal withdrawal syndrome, opium, pregnancy, substance abuse.

Abstract
Background: Laparoscopic cholecystectomy is the gold standard for treating gallbladder diseases; however, it is associated with physiological challenges from pneumoperitoneum and specific patient positioning. Positive end-expiratory pressure (PEEP) may mitigate these effects, but the optimal level remains uncertain. This study compared the impact of three PEEP levels on respiratory performance and hemodynamic stability during laparoscopic cholecystectomy.
Methods: This randomized double-blind clinical trial was conducted at Shahid Mohammadi Hospital, Bandar Abbas, Iran, from August 2023 to February 2024. A total of 75 adult patients aged 18-70 years with ASA class I-II scheduled for elective laparoscopic cholecystectomy were assigned to three groups (n=25 each): PEEP 0 cmH₂O (control), PEEP 5 cmH₂O, and PEEP 7 cmH₂O. Standardized general anesthesia and mechanical ventilation with tidal volumes of 6-8 mL/kg were applied. Hemodynamic variables (mean arterial pressure, heart rate) and respiratory parameters (SpO₂, EtCO₂) were recorded before intubation, during intubation, and at 15, 30, and 60 minutes post-intubation, as well as in the recovery room. Arterial blood gas analysis was performed 30 minutes after intubation. Data were analyzed using ANOVA and chi-square tests with a significance level of 0.05.
Results: The mean age of patients was 41.89±11.39 years, and baseline demographic variables showed no significant differences among groups. Oxygen saturation remained above 94% across all time points without intergroup differences. EtCO₂ values differed significantly at 30 minutes (P=0.04) and 60 minutes (P=0.01), with the highest levels observed in the PEEP 7 group and the lowest in the PEEP 5 group. Although mean arterial pressure and heart rate did not show statistically significant variation among groups, the PEEP 7 group demonstrated the smallest postoperative decline in blood pressure.
Conclusion: A PEEP level of 5 cmH₂O offers the most favorable balance between maintaining oxygenation, supporting effective ventilation, and preserving hemodynamic stability during laparoscopic cholecystectomy. This level can be recommended as a safe and optimal ventilation strategy.

Abstract
Background: Pelvic organ prolapse (POP) is a condition resulting from weakness or damage to the muscles, ligaments, and other supporting structures of the vagina, and it exposes affected women to reduced quality of life and sexual function. The present study examined the symptoms, sexual function, and quality of life of women one year after repair of pelvic organ prolapse.
Methods: This study was a prospective cohort before-after study that was conducted on 200 married women with pelvic prolapse grade 1-4 (POP-Q) in the age group of 47-75 years who underwent reconstructive surgery (anterior and posterior colporrhaphy) in Shahid Beheshti and Al-Zahra hospitals in Isfahan between October 2022 and March 2024. The data collection tools were three questionnaires: Female Sexual Function Index (FSFI), Pelvic Discomfort (PFDI-20) and Quality of Life (SF-36) which were completed before surgery and one year after surgery. Stata software version 17 was used to analyze the data. To compare the scores before and after, paired t-test or Wilcoxon statistical tests were used, to compare the severity of patients' clinical symptoms based on the levels before and after surgery, the symmetry/Bowker test was used, and to compare the status of the sexual function index (impairment/no impairment) before and after surgery, the McNemar test was used and the significance level was considered to be P<0.05.
Results: The mean age of the study participants was 59.5±12.6 years. The majority of the women (157 individuals; 78.5%) were housewives. The mean number of pregnancies was 4.3±2.1, and the mean number of live births was 3.75±1.89. All women included in the study were postmenopausal. The severity of clinical symptoms, sexual dysfunction index status, and median quality of life score were significant between before and after the intervention. The severity of clinical symptoms, the status of the sexual dysfunction index, and the median quality of life score showed significant differences before and after the intervention.
Conclusion: Pelvic prolapse surgery can significantly improve the quality of life and sexual function of patients one year after surgery, in addition to correcting the anatomical structure.

Abstract
Background: In general anesthesia, anesthetic agents are administered by inhalation or intravenously, leading to loss of consciousness, immobility, analgesia, and amnesia. In spinal anesthesia, injection of a local anesthetic into the intrathecal space causes sensory and motor block. The aim of this study was to compare the volume of bleeding during cesarean section under general anesthesia and spinal anesthesia.
Methods: This study is a cross-sectional prospective study. The gauzes used were weighed before the operation and bloody gauzes were weighed after the operation. The difference between the weight of bloody and dry gauzes was recorded as the volume of bleeding. This volume was then added to the volume of blood in the suction chamber and the final bleeding volume was estimated.
Results: 70 patients who were candidates for cesarean section were included in the study. The mean age of the patients included in the study was 24.82±4.98 and their mean weight was 77.11±8.97. The mean hemoglobin in the spinal anesthesia group was 91.12±39. Volume of bleeding during cesarean section by spinal anesthesia was significantly less than general anesthesia (P=0.001). Also, the visual estimation of bleeding in spinal anesthesia was significantly lower than general anesthesia (P<0.001). In this study, there was no significant difference between heart rate, systolic and diastolic pressure before and during surgery, and the first- and fifth-minute Apgar scores between the two groups of general and spinal anesthesia.
Conclusion: We found in this study that the volume of bleeding during cesarean section under spinal anesthesia is less than general anesthesia. It is suggested that in future studies, other methods of estimating bleeding such as postoperative hemoglobin reduction, dilution method, atomic absorption spectroscopy and photometry be used. Also, a comparison should be made between the three groups of general, spinal and epidural anesthesia, and the volume of bleeding in each should be checked and the best anesthesia method should be selected for cesarean section.

Abstract
Background: The Southern endotracheal tube facilitates surgical access and reduces the risk of tube torsion. Fiberoptic laryngoscopy also improves the accuracy and safety of intubation. Accordingly, the present study aimed to determine the precise placement of the Southern endotracheal tube using fiberoptic laryngoscopy in elective surgeries under general anesthesia.
Methods: This descriptive-analytical prospective study was conducted between April 2025 and July 2025 at Al-Zahra and Ayatollah Kashani Centers of Isfahan University of Medical Sciences. Sampling was performed using a convenience method, and the sample size was estimated at 100 patients (candidates for elective head, face, and nasal surgeries), considering possible dropouts. Data were collected using a checklist and analyzed with SPSS version 27.
Results: In this study, the demographic and clinical characteristics of the patients showed that the mean age was 38.88±15.92 years, and 53% were male, and 47% were female. The results indicated that body mass index, neck circumference, and the distance from the tip of the endotracheal tube to the anterior teeth differed significantly between male and female patients (P<0.05). Specifically, Body Mass Index (BMI) was significantly higher in females, neck circumference was significantly greater in males, and the distance from the tube tip to the anterior teeth was longer in males. Additionally, BMI, the distance from the carina to the anterior teeth, and the distance from the endotracheal tube to the carina showed significant differences among different age groups (P<0.05).
Conclusion: The present study demonstrated that the depth and placement of the endotracheal tube are influenced by factors such as BMI. These findings are consistent with previous studies emphasizing the importance of individual assessment to optimize airway management. Overall, fiberoptic-guided intubation should be considered the gold standard for achieving accurate tube positioning, minimizing the risk of airway complications, and improving intraoperative safety. It is suggested that future studies focus on developing predictive models for optimal tube depth based on demographic and anatomical variables, and on evaluating the impact of these strategies on postoperative outcomes.

Abstract
Background: The present study is a systematic and comparative review of the studies conducted in the field of hospice centers for patients with acute incurable diseases with a life expectancy of less than six months in the world with the aim of examining the need in Iran and the experiences of other countries, identifying candidates to receive these services, type of services provided, costs and resources in these centers.
Methods: The present study was conducted as a systematic review by searching the databases: Scopus, PubMed, Elsevier, and Google Scholar search engine between 2010 and 2023. To search these databases, keywords such as hospice care centers, centers providing health services for patients with life expectancy less than six months, allocation of resources, allocation were used. After selecting the articles, the following topics were extracted from each article and compared: costs, sources of funding, candidates for receiving services, families' views, quality of near-death care, quality of life, quality of death, services provided, therapeutic interventions performed, place of death, length of stay.
Results: 6 articles referred to the discussion of cost, and in all articles except one case, the use of hospice was associated with reducing the cost of patients. In one study, the source of funding was philanthropic contributions and in another study, the national budget. In all the reviewed articles, the use of hospice was associated with an increase in the quality of care, quality of end of life and quality of death, and a decrease in therapeutic interventions. The care provided by hospice was also introduced in the form of symptom assessment and management, pain relief, psychosocial support and respite care.
Conclusion: Based on the findings of the present study, hospices can play an effective role in reducing treatment costs and, on the other hand, improve the quality of care, life and death in eligible people. In addition, hospices improved the end-of-life quality from the perspective of the deceased's family by reducing invasive interventions and providing physical and spiritual care.

Abstract
Background: Postoperative pain remains a major concern following abdominal surgeries, including laparoscopic cholecystectomy. Inadequate pain control may lead to increased opioid consumption, delayed recovery, prolonged hospitalization, and reduced patient satisfaction. Therefore, the use of anesthetic adjuvants with effective analgesic properties and minimal side effects has gained increasing attention. Ketamine, an N-methyl-D-aspartate (NMDA) receptor antagonist, and dexmedetomidine, a highly selective α2-adrenergic agonist, are commonly used agents with distinct mechanisms of action. The present study aimed to compare the effects of intraoperative ketamine and dexmedetomidine on postoperative pain following laparoscopic cholecystectomy.
Methods: This randomized, double-blind, controlled clinical trial was conducted on 252 patients undergoing elective laparoscopic cholecystectomy. Patients were randomly assigned into three equal groups: ketamine, dexmedetomidine, and control. The ketamine group received an intravenous infusion of ketamine at a dose of 0.5 mg/kg/h, the dexmedetomidine group received 0.6 µg/kg/min of dexmedetomidine, and the control group received normal saline. Pain intensity was assessed using the Visual Analogue Scale (VAS) at 1, 6, 12, and 24 hours postoperatively. Hemodynamic parameters, including heart rate and mean arterial pressure, were continuously monitored throughout the perioperative period. Data were analyzed using appropriate statistical tests, including ANOVA and nonparametric analyses.
Results: The results demonstrated that postoperative pain scores were significantly lower in the ketamine group compared to both the dexmedetomidine and control groups at all evaluated time points within the first 24 hours after surgery (P < 0.001). Although dexmedetomidine also provided effective analgesia compared with the control group, ketamine showed superior pain reduction. No statistically significant differences were observed among the three groups regarding hemodynamic parameters, indicating comparable cardiovascular stability.
.Conclusion: Intraoperative administration of ketamine was more effective than dexmedetomidine in reducing postoperative pain following laparoscopic cholecystectomy, without compromising hemodynamic stability. Nevertheless, both agents proved to be safe and effective options for postoperative pain management. Ketamine may be considered a preferable.

Abstract
Background: Cisplatin is one of the most effective chemotherapy agents; however, its nephrotoxicity remains the primary dose-limiting factor. This study aimed to determine the prevalence and clinical course of acute kidney injury (AKI) in patients receiving high-dose cisplatin therapy.
Methods: This cross-sectional descriptive study was conducted at Ayatollah Khansari Hospital in Arak, based on clinical records of hospitalized patients from March 2021 to June 2022. Patients who received at least four cycles of cisplatin-based chemotherapy at a dose of 260 mg/m² were included. Data were extracted from the Hospital Information System (HIS) and physical records. Ninety eligible cases were selected via random sampling. Data were summarized using descriptive statistics.
Results: Regarding gender distribution, 54.4% were female (n=49) and 45.6% were male (n=41). The relative frequency of cisplatin-induced AKI was 21.11%. Overall, 26.32% of patients developed chronic kidney disease (CKD), 10.53% reached end-stage renal disease (ESRD), and only 11.42% recovered. An 18 to 24-month follow-up revealed a mortality rate of 21.05%, while 15.79% required treatment modification, and 5.26% needed kidney transplantation. No treatment discontinuation was observed. Logistic regression analysis identified female gender, age 61-70, age >70, poor hydration status, five or more chemotherapy cycles, and diabetes mellitus as significant risk factors for AKI.
Conclusion: High-dose cisplatin is associated with a high risk of permanent renal damage. Given the low recovery rate and the potential for progression to chronic renal failure, careful monitoring of risk factors and rigorous hydration management are vital for these patients.

Abstract
Background: Type 1 diabetes mellitus, with its increasing prevalence in the pediatric population, has a significant impact on the mental health, quality of life, and lifestyle of patients.. The onset of the disease in childhood and its association with the child during school and adolescence, and during the growth and development process, has numerous effects on the growth process and mental experiences of patients.
Methods: This cross-sectional study was conducted in Children, s Medical Center from march 2022 to February 2023 on 183 patients with type 1 diabetes aged 9 to 18 years. The duration of the disease ranged from 1 year to 15 years. 44% of the populations were girls and 56% were boys. 77% were under 13 years of age and the rest were over 13 years of age. Information was completed by parents in the Achenbach electronic questionnaire (112 questions). Then, based on the standard defined for the questionnaire, the scores were classified into clinical, borderline, and normal categories.
Results: No significant differences were observed between the two sexes in terms of the incidence of various disorders. However, significant differences in the incidence of externalizing problems have been reported at different ages and different disease durations. Analysis of the mean T-scores of the studied patients showed that there were significant differences between patients older than 13 years younger than 13 years in terms of externalizing problems, anxiety/depressive disorders, attention deficit/hyperactivity disorders, law-breaking behavior, internalizing problems, and general problems. a significant relationship was observed between the study population and the duration of the illness in terms of aggressive problems, law-breaking problems, and externalizing disorders.
Average scores in externalizing disorders, affective/depressive disorders, law-breaking behavior, internalizing problems, and general problems were significantly related to different ages.
Conclusion: The results of this study show that as patients aging and more than 5 years since the onset of diabetes, the risk of developing psychiatric disorders increases. As a result, routine psychiatric screening is recommended for these children.

Background: Nonalcoholic fatty liver disease (NAFLD) is one of the most prevalent chronic liver diseases worldwide and is closely associated with metabolic syndrome and insulin resistance. Growing evidence suggests a link between NAFLD and cardiovascular diseases, independent of traditional risk factors. Coronary computed tomography angiography (CCTA) is a reliable noninvasive method for evaluating coronary artery disease (CAD) and identifying high-risk coronary plaque characteristics. However, data regarding the association between NAFLD and high-risk coronary plaques remain limited, particularly in Iran. This study aimed to evaluate the prevalence of NAFLD in patients with high-risk coronary plaques detected by CCTA.
Methods: In this cross-sectional study, 200 patients who underwent CCTA for the evaluation of coronary plaques in outpatient clinics or the emergency department of Golestan Hospital in ahvaz ,1403 ,were enrolled. Demographic data, including age, sex, weight, and body mass index (BMI), along with clinical characteristics and cardiovascular risk factors such as hypertension, diabetes mellitus, dyslipidemia, smoking status, and medical history were collected. Patients with a history of alcohol consumption or known liver disease were excluded. NAFLD was assessed based on imaging findings. Statistical analyses were performed to compare variables between patients with and without NAFLD.
Results: The mean age of patients with NAFLD was 57.89 ± 9.72 years, compared with 55.77 ± 8.97 years in patients without NAFLD, with no statistically significant difference. The prevalence of NAFLD was slightly higher in women than men; however, this difference was not significant. Patients with NAFLD had a significantly higher mean weight than those without NAFLD (85.21 ± 12.12 kg vs. 79.62 ± 11.85 kg; p = 0.001). Additionally, the prevalence of NAFLD increased significantly with higher BMI categories, particularly in obese individuals.
Conclusion: Age and gender were not significantly associated with NAFLD prevalence in patients with high-risk coronary plaques. In contrast, increased body weight and higher BMI, especially obesity, were independently associated with a higher risk of NAFLD in this population.

Abstract
Background: The duration of hospitalization of patients is considered an important indicator in health resource management and patient evaluation. This study investigated the frequency and causes of readmission in cardiovascular patients
Methods: This was a retrospective study of 105 patients with cardiovascular diseases referred to Imam Khomeini Hospital in Ahvaz who were readmitted from April 2024 until August 2024 within 30 days after discharge due to recurrence of symptoms. Demographic (including age and gender) and clinical information (including duration of hospitalization, regular medication use, regular physician visits, disease diagnosis and dietary adherence) of the patients was extracted from electronic records using a researcher-made checklist.
Results: From 105 patients, 43 (41%) were admitted in the first trimester and 62 (59%) in the second trimester. The mean age of patients in the first trimester was higher than in the second trimester with a statistically significant association with readmission (P=0.038). Most patients were male and their number was higher in the second trimester than in the first trimester and a statistically significant association was observed between the gender of patients with readmission in the first trimester compared to the second trimester (P=0.015). 72 patients with acute coronary syndrome (68.6%) and 33 patients with heart failure (31.4%) were readmitted. The mean length of stay in the first trimester was 1.6 ± 1.15 days and 2.9 ± 2.7 days in the second trimester. A significant association was observed between the duration of hospitalization and readmission (P=0.003). However, no association was observed between regular medication use and regular physician visits in readmitted patients. However, a significant association was observed between dietary adherence in readmitted patients (P=0.045).
Conclusion: Readmission of cardiovascular patients follows a seasonal pattern and is associated with factors such as age, sex, length of stay, and dietary adherence. Routine disease management measures are not sufficient to counteract these effects, and targeted educational programs are necessary at the threshold of high-risk periods.

Abstract
Background: With the rapid advancement of minimally invasive surgical techniques, laparoscopic cholecystectomy has become one of the most frequently performed procedures worldwide. Despite its benefits, such as reduced postoperative complications and faster recovery, effective pain management remains a critical challenge. Postoperative pain can significantly impact patient recovery, hospital stay duration, and overall satisfaction. Given the limitations and side effects of opioid-based analgesics, there is growing interest in non-opioid alternatives for pain control following laparoscopic cholecystectomy. This narrative review evaluates the efficacy of various non-opioid analgesics in managing postoperative pain in patients undergoing this procedure.
Methods: A comprehensive literature search was conducted across multiple electronic databases, including Scopus, PubMed, Science Direct, SID, Magiran, and Google Scholar, using both Persian and English keywords. English equivalents were "Pain" and "Laparoscopic Cholecystectomy." Studies discussing pharmacological interventions for postoperative pain management in laparoscopic cholecystectomy were included.
Results: The review identified a wide range of non-opioid analgesics used for pain control in laparoscopic cholecystectomy patients. These included: Systemic medications (intravenous/oral) were magnesium sulfate, ketamine, ketorolac, paracetamol, ibuprofen, pregabalin, gabapentin, acetazolamide, N-acetylcysteine, dexamethasone, clonidine, celecoxib, and diclofenac. Local anesthetics & adjuvants were used intraperitoneally like bupivacaine, lidocaine, and hydrocortisone. Administration routes varied, with most drugs given intravenously, intraperitoneally, or preemptively (e.g., celecoxib and clonidine before surgery). Some studies highlighted the benefits of multimodal analgesia, combining different drug classes to enhance pain relief while minimizing side effects.
Conclusion: Despite the availability of numerous non-opioid analgesics, no single drug has been universally endorsed as the gold standard for postoperative pain management in laparoscopic cholecystectomy. Current evidence suggests that the choice of analgesic should be individualized, considering patient factors (e.g., comorbidities, pain tolerance) and the anesthesiologist’s expertise. Multimodal approaches, combining different drug classes, may offer superior pain control with fewer adverse effects compared to monotherapy. Further high-quality randomized trials are needed to establish standardized protocols and optimize pain management strategies for these patients.

Abstract
Background: Subarachnoid hemorrhage (SAH) is a life-threatening emergency condition often accompanied by severe, sudden-onset headache. The main causes are head trauma and aneurysm rupture. Pain management in these patients remains challenging, typically requiring opioids which carry significant adverse effects. As anti-neuropathic agents, gabapentin and pregabalin may serve as suitable alternatives to opioids. This systematic review aimed to evaluate the efficacy and safety of gabapentin and pregabalin in managing SAH-associated headaches.
Methods: Following PRISMA guidelines, we conducted comprehensive searches in PubMed, SCOPUS, Web of Science, and EMBASE through May 2025. Key search terms included "Gabapentin," "Pregabalin," "Subarachnoid Hemorrhage," and "Headache." After initial screening, we selected English or Persian-language articles investigating these medications' effects on SAH-related headache. After removal of duplicates and screening, four eligible studies (including randomized controlled trials and cohort studies) were included for final analysis. Data on study type, sample size, type of interventions, headache management-related outcomes, as well as safety and tolerability profiles were extracted.
Results: Pregabalin demonstrated significant efficacy, showing a statistically significant reduction in pain intensity compared to placebo before anesthesia induction (P≤0.004) and up to 24 hours post-operatively (P=0.007). Additionally, patients receiving pregabalin required significantly fewer rescue analgesics (P≤0.005). In contrast, gabapentin did not produce a statistically significant reduction in pain intensity or morphine equivalent requirements compared to placebo, although a non-significant trend toward decreased pain was observed. Safety profiles were favorable for both medications; no serious adverse events leading to drug discontinuation were reported.
Conclusion: Pregabalin appears to be an effective, safe, and well-tolerated option for managing SAH-related headache, significantly reducing both pain intensity and opioid requirements. Current evidence for gabapentin remains limited and inconclusive, warranting further large-scale, randomized controlled trials to confirm its potential role in this setting.

Abstract
Background: Congenital scoliosis (CSC) and Idiopathic scoliosis (ISC) are complex spinal disorders that may involve neurological components affecting bladder function. Surgery remains the primary treatment for significant deformity, and in selected cases, correction of an associated tethered cord is also required. Given the potential interaction between spinal pathology and lower urinary tract function, this study examined changes in urodynamic findings before and after treatment in patients with CSC and ISC.
Methods: This retrospective cross-sectional study included patients with scoliosis who were presented to the Neurosurgery Clinic at Sina Hospital between September 2016 and September 2018. Preoperative and postoperative urodynamic study (UDS) results were reviewed, and statistical analyses were performed using SPSS version 24.
Results: Thirty-one patients were analyzed, consisting of 10 males (32.2%) and 21 females (67.7%), with a mean age of 14.18 years (median: 13 years). Among the 12 patients with CSC, 10 (83.3%) showed abnormal UDS prior to surgery. In contrast, 13 of 19 patients with ISC (68.4%) demonstrated normal baseline UDS. Following treatment, normalization occurred in 10 CSC patients (83.3%) and in 14 ISC patients (73.7%) (P=0.008). Before surgery, 15 of the 23 patients without a tethered cord (65.2%) had normal UDS, whereas all 8 patients with a tethered cord exhibited abnormal findings. Of the 12 patients with abnormal preoperative UDS, 3 (25%) showed no postoperative change, while 12 patients demonstrated normalization and 4 continued to show abnormal results (McNemar test, P=0.039). Improvement was also observed in 7 of the 8 patients (87.5%) with a tethered cord (P=0.57).
Conclusion: Scoliosis surgery, particularly when combined with tethered cord release, was associated with meaningful improvement in urodynamic function. Urodynamic abnormalities were more common among CSC patients before intervention, and the presence of a tethered cord contributed to greater urinary dysfunction across both scoliosis types. These findings highlight the importance of thorough preoperative urodynamic assessment to guide management and anticipate postoperative outcomes.

Abstract
Background: Severe spinal kyphosis, particularly in patients with sagittal imbalance and high Pelvic incidence (PI), represents one of the most challenging conditions in spinal surgery. This deformity is commonly associated with chronic pain, functional limitation, and a decreased quality of life.
Case Presentation: A 66 year old woman presented with progressively worsening radicular pain, gait impairment, early fatigue while standing, and a severe kyphotic deformity with marked sagittal imbalance. Her history was significant for an instrumented lumbar fusion from L3 to S1 performed in March 2023, complicated by persistent right foot drop, followed approximately five weeks later by rehospitalization for herpetic encephalitis; concurrent imaging demonstrated inflammatory changes at the L5-S1 disc space suspicious for discitis, although CT guided biopsy cultures were negative. Her medical comorbidities included type 2 diabetes mellitus and prior coronary artery bypass grafting. Radiographic and spinopelvic analysis revealed adjacent segment disease at L2-L3 and severe sagittal malalignment with a pelvic incidence of 88°, lumbar lordosis of 30°, and sagittal vertical axis of 25 cm. Given the significant PI-LL mismatch and progressive postural collapse, revision deformity surgery was indicated. The patient underwent a Smith-Petersen osteotomy at L5-S1 with long segment posterior fixation from T11 to S2, including iliac screw fixation, between August and September 2025. Postoperatively, lumbar lordosis improved to 45°, pelvic incidence decreased to 65°, and global sagittal alignment was restored, resulting in marked pain relief, improved standing tolerance, correction of spinal balance, and stable neurological status during recovery.
Conclusion: Postoperatively, significant improvement in sagittal balance was achieved, with LL increasing to 45° and PI decreasing to 65°, leading to marked functional recovery and pain relief. This case powerfully demonstrates the correlation between a high Pelvic incidence (PI) and prior surgical failure. It serves as an important didactic example in understanding the biomechanical drivers of sagittal deformity, emphasizing the optimization of safer, corrective surgical techniques for high-risk, complex patients to ensure durable global alignment.
