Abstract
Background: Diabetes is known to be linked with a high risk of liver stiffness in non-alcoholic fatty liver patients. Previous studies have faced challenges in examining the association between prediabetes and liver stiffness. This study aimed to compare liver fibrosis in diabetes and prediabetes patients.
Methods: This cross-sectional descriptive study was conducted on patients with diabetes and prediabetes who were referred to Imam Khomeini Hospital in Ahvaz from March 2022 to March 2023. The study aimed to clear the relationship between liver stiffness and age, gender, BMI, AST, ALT, ALKP, Bilirubin, and the type of treatment. The normality of quantitative variables was checked using the Kolmogorov-Smirnov test. The chi-square test examined two qualitative variables with more than two levels.
|
Results: Out of the total participants, 53 people (63.9%) had diabetes, while 30 people (36.1%) had prediabetes. There was a significant difference between the mean severity of liver fibrosis in diabetic and pre-diabetic patients (P=0.014). The frequency of liver stiffness in all levels except in the group with mild or no fibrosis (F0-F1) was higher in diabetic than pre-diabetic patients. In both diabetes and prediabetes groups, there was no significant relationship between gender, age, BMI, ALT, and ALKP with liver fibrosis. However, there was a significant direct relationship between HbA1C% and liver fibrosis (P≥0.003) in both groups. In diabetic patients, a significant relationship between FBS and liver fibrosis was observed (P=0.001). In pre-diabetic patients, significant direct relationship was seen between the severity of liver fibrosis and AST levels (P=0.026).
Conclusion: Diabetic patients showed a higher severity of liver fibrosis compared to pre-diabetic patients. No statistically significant relationship was seen between liver fibrosis and age, sex, body mass index, ALT, and ALKP in both groups. Additionally, both diabetes and prediabetes groups showed significant relationship between liver fibrosis and HbA1C (P≥0.003). Prediabetes was also found to be associated with an elevated risk of liver fibrosis.

Abstract
Background: Recently, epinephrine is used to increase the depth and duration of local anesthetic pain, and it is widely used topically to reduce local anesthetic release and reduce bleeding caused by surgery.
Methods: This study was a randomized, double-blind clinical trial on 30 patients aged 18 to 85 years undergoing lower limb orthopedic surgery referred to Peymaniyeh Hospital in Jahrom from September to December 2022. Patients were randomly assigned to two groups, A (epinephrine+fentanyl+bupivacaine) and B (bupivacaine+fentanyl). Systolic blood pressure, diastolic pressure, mean arterial pressure, arterial blood oxygen saturation percentage, and pulse rate were measured and recorded before drug administration, before spinal anesthesia, after anesthesia, and then every half hour until the end of surgery (15, 45, 30, 60, 75, 90, 120) and during recovery. Data analysis was performed using SPSS version 21 software and descriptive (mean, standard deviation) and inferential statistics (t-test, chi-square, Mann-Whitney, Friedman) at a significance level of P<0.05.
|
Results: Thirty patients aged 18 to 85 years (in two groups of 15) with anesthesia class I and II undergoing lower limb orthopedic surgery were evaluated. The study groups are matched in terms of age and gender variables. There was no significant difference in mean systolic, diastolic, mean arterial blood pressure, and heart rate before and after anesthesia, 15, 45, 30, 60, 75, 90, and 120 minutes after drug injection, and at entry and exit from recovery between the Epinephrine+Fentanyl+Bupivacaine and Fentanyl+Bupivacaine groups. There was a significant difference in mean O2SAT before anesthesia, 15, 30, and 75 minutes after drug injection between the epinephrine+fentanyl+bupivacaine and fentanyl+ bupivacaine groups (P<0.05).
Conclusion: The use of the combination of epinephrine+fentanyl+intrathecal bupivacaine compared to the combination of fentanyl+bupivacaine did not have a significant difference in the studied variables of patients' vital signs.

Abstract
Background: Problems related to blue light exposure are among the various issues experienced by individuals who have undergone Photorefractive Keratectomy (PRK).Given the growing concerns regarding blue light’s effects on visual health, this study aimed to thoroughly investigate the impacts of blue blocker filters on the improvement of vision in patients post-refractive surgery of the PRK type. The primary objective was to evaluate the overall effectiveness of these filters in enhancing visual quality and in reducing complications associated with the surgery, which can significantly affect a patient’s quality of life.
Methods: In a quasi-experimental study conducted from September 1, 2024, to the end of October 2024, individuals who had undergone PRK surgery were examined at the optometry clinic of Dr. Labbafi Nejad Hospital in Tehran. Participants were subjected to assessments both with and without the application of blue blocker filters. Key parameters, including visual acuity and contrast sensitivity among attendees, were meticulously measured under both conditions. The results were then systematically compared and analyzed to draw meaningful conclusions about the impact of blue blocker filters in this context.
|
Results: A total of thirty-four participants, comprising 73.5% females and 26.5% males, with an average age of 32.6 years, were incorporated into the study. Post-surgery, the average refraction measured in the right and left eyes was documented as -0.42±0.16 D and -0.30±0.16 D, respectively. Notably, visual acuity in both eyes significantly improved with the use of the blue light blocking filter (P<0.005) Moreover, contrast sensitivity at varying spatial frequencies of 1.5, 6, and 18 cycles per degree (c/d) also exhibited significant enhancement (P<0.005).
Conclusion: The incorporation of blue blocker filters for individuals with a history of PRK surgery has led to noteworthy improvements in visual acuity and enhanced contrast sensitivity. These findings underscore the critical importance of integrating blue light protection in the post-operative care of patients, as it significantly elevates the overall visual experience and may contribute to better long-term outcomes following refractive surgery.

Abstract
Background: Androgenetic alopecia is the most common cause of hair loss, and its prevalence increases with age. Different studies have reported different results regarding the association of cardiovascular diseases with androgenetic alopecia. The present study aimed to The present study aimed to Investigating the relationship between androgenetic alopecia and the thickness of the intima media of the carotid artery in the referrals to the specialized skin and hair clinic of Allameh Bohlool Gonabadi Hospital.
|
Methods: This case-control study was conducted from October 2021 to June 2022 on 100 patients referred to the Skin and Hair Clinic of Allameh Bahloul Hospital in two groups of 50 cases and controls, aged less than 40 years. The subjects were matched in terms of age and gender. Patients with alopecia were classified into three categories: mild, moderate, and severe based on the diagnosis of the treating physician. The thickness of the intima-media layer of the carotid artery was measured using ultrasound.
Results: There were 37 males and 13 females in both the case and control groups. The mean age in the case group was 29.50 and 30.28 years, respectively. In addition, the duration of alopecia in the case group was 6.9 years. Although the results indicated that the carotid artery intima-media thickness was higher in patients with androgenetic alopecia, no statistically significant relationship was found between androgenetic alopecia and carotid artery intima-media thickness (P=0.66). There was also a statistical relationship between the carotid artery intima-media thickness and the duration of alopecia (P=0.03).
Conclusion: Considering the relationship between the thickness of the intima media of the carotid artery and the duration of alopecia, it can be said that there is a possible relationship between alopecia and atherosclerosis, but to prove it, studies with a larger sample size are needed.

Hyperthyroidism is one of the most important endocrine disorders, characterized by increased activity of the thyroid gland and excessive production of thyroid hormones. These hormones play a key role in regulating the body’s metabolism; therefore, their excess leads to a wide range of clinical manifestations. The most common symptoms include anxiety, restlessness, weight loss despite normal or even increased appetite, palpitations, excessive sweating, fine tremors of the hands, sleep disturbances, and heat intolerance. Some patients may also experience mood changes such as irritability and nervousness. On physical examination, rapid tendon reflexes, tachycardia, moist and thin skin, and in many cases the presence of goiter (thyroid enlargement) may be observed. The condition is more common in women than men and is most frequently seen between the ages of 20 and 50 years. Once hyperthyroidism is confirmed, the underlying cause of thyrotoxicosis must be determined. The most common cause is Graves’ disease, an autoimmune disorder that leads to diffuse thyroid enlargement and overproduction of hormones. Toxic multinodular goiter and solitary toxic adenoma are other important causes. For definitive diagnosis, blood tests measuring TSH, T3, and T4 are essential. In hyperthyroidism, TSH is typically suppressed while T3 and T4 are elevated. In addition to laboratory testing, thyroid ultrasound can help evaluate the structure of the gland, and a thyroid radioactive iodine uptake scan can further differentiate between different causes and determine disease activity. Several treatment options are available for managing hyperthyroidism. Antithyroid drugs such as methimazole or propylthiouracil inhibit the synthesis of thyroid hormones. Beta-blockers are often prescribed to control cardiovascular symptoms and reduce palpitations. Radioactive iodine therapy is a common and effective method that destroys the overactive thyroid tissue. In rare cases, or when other treatments fail, thyroidectomy (surgical removal of part or all of the thyroid gland) may be required. Overall, hyperthyroidism is a manageable condition, but it requires accurate diagnosis, careful selection of therapy, and close follow-up with a specialist. Patient cooperation and adherence to treatment play a crucial role in controlling symptoms and preventing long-term complications. This review will focus on describing the symptoms, causes, diagnostic methods, and treatment options.

Abstract
Background: Hydrochlorothiazide (HCTZ) is widely used for hypertension, but electrolyte disorders-especially hyponatremia remain major safety concerns. Limited regional data on its prevalence, timing, and determinants may undermine patient safety. This retrospective study evaluated risk factors for HCTZ-associated hyponatremia in hospitalized adults with hypertension and identified predictors of its severity.
Methods: A retrospective analysis was conducted on 217 patients hospitalized at Ayatollah Rouhani Hospital in Babol (2019-2021). Eligible participants were aged ≥18 years and had received HCTZ for at least seven consecutive days. Patients with baseline hyponatremia, concurrent use of drugs independently causing hyponatremia, or incomplete laboratory data were excluded. Demographic, clinical, medication, and biochemical variables were abstracted from medical records. Hyponatremia was defined as serum sodium <135 mmol/L and categorized as mild (130-134), moderate (125-129), or severe (<125). Predictors of occurrence were estimated with multivariable logistic regression; onset timing was assessed using a Cox proportional hazards model; and severity determinants were examined through multinomial logistic regression. Statistical significance was set at P<0.05.
Results: Hyponatremia occurred in 32.7% (71.217) of patients, most frequently within the early weeks of HCTZ treatment. Among affected individuals, 49.3% had mild, 31.0% moderate, and 19.7% severe hyponatremia. Adjusted analyses showed that older age, concurrent nonsteroidal anti-inflammatory drug (NSAID) use, shorter HCTZ duration, and lower serum potassium and uric acid independently increased hyponatremia risk, while HCTZ dose and sex were nonsignificant. In the Cox model, older age and lower potassium and uric acid predicted earlier onset. Patients with hyponatremia more often presented with weakness, headache, altered consciousness, and seizures. Baseline glucose, creatinine, and most comorbidities were not independently associated with risk or timing.
Conclusion: HCTZ-related hyponatremia was common and typically emerged soon after initiation. Advanced age, NSAID co-administration, brief exposure, and reduced potassium and uric acid were practical, readily measurable markers associated with both occurrence and earlier onset. Routine early and repeated electrolyte monitoring particularly in older adults and patients receiving NSAIDs- together with patient education on warning symptoms is recommended. These findings highlight key predictors for targeted surveillance and prevention in similar clinical contexts.

Abstract
Background: Patients with type 2 diabetes mellitus (T2DM) are diagnosed with a wide range of renal damage, usually presenting with albuminuria and decreased estimated Glomerular Filtration Rate (eGFR). Some patients have only albuminuria and normal eGFR, while others have normoalbuminuria even in advanced stages of chronic kidney disease. This study investigated and followed the course of diabetic nephropathy in patients with T2DM.
Methods: 1107 patients with T2DM were enrolled in the study. This historical cohort was conducted between the years 2017 and 2022. Patients with confirmed type 2 DM, referred to the diabetes clinic of Vali-Asr Hospital, affiliated with the Tehran University of Medical Science. Complete medical history, blood pressure, and laboratory data were obtained in the first and follow-up visits. Follow-up was every 3 to 6 months for 30 months. Every year, 24-hour urinary albumin was measured, and eGFR was estimated based on the Cockcroft-Gault formula.
Results: Male sex, age, disease duration, weight, systolic blood pressure, 2 hours postprandial (2hpp) glucose, serum triglyceride, and uric acid significantly correlated with albuminuria. At the initiation of the study, the highest eGFR values occurred in microalbuminuric patients, followed by a sharp decrease. No significant correlation was found between eGFR and albuminuria in most patients, and more than half of them with eGFR of less than 60 ml/min/m2 still had normal albuminuria
Conclusion: This study showed that patients with microalbuminuria and normoalbuminuria had the highest eGFR values followed by macroalbuminuria, but patients with normoalbuminuria and microalbuminuria had an initial increase and then a decrease, and the macroalbuminuria group showed the sustained and greatest decrease during the follow-up period. Serial surveillance of both albuminuria and GFR is crucial in T2DM.

Abstract
Background: Thyroid disorders are common among young women, and hypothyroidism ranges clinically from subclinical to overt disease, potentially causing various maternal and fetal complications. Determining the appropriate levothyroxine (LT4) dose during pregnancy is crucial for maintaining maternal euthyroidism and optimising pregnancy outcomes. This study aimed to evaluate the dose requirements of LT4 in pregnant women with and without a prior history of hypothyroidism, and to investigate the association with Thyroid peroxidase antibody (TPO) levels.
Methods: This hospital- and clinic-based study was conducted from September 2022 to March 2023 among 146 pregnant women attending a private clinic or Golestan Hospital in Ahvaz, Iran. A total of 146 pregnant women diagnosed with subclinical hypothyroidism (SCH, n=62) or overt hypothyroidism (OH, n=84) were randomly selected. Participants were divided into groups based on their history of hypothyroidism and received LT4 treatment. LT4 requirements were determined according to trimester-specific TSH ranges: >10 mIU/L or 2.5-10 mIU/L in the first trimester, and 3-10 mIU/L in the second and third trimesters. Data analysis was performed using SPSS version 22, employing descriptive statistics (mean±SD, frequency, and percentage) and analytical tests, including the independent t-test and Mann-Whitney U test.
Results: Pregnant women with overt hypothyroidism showed a statistically significant difference in mean LT4 dose between those with and without a prior history of hypothyroidism (P<0.05). In contrast, no significant difference was observed in LT4 requirements among women with subclinical hypothyroidism. TPO Ab positivity was associated with higher LT4 requirements, particularly in women with overt disease. Dose adjustments were most frequent during the first trimester, with incremental increases observed in subsequent trimesters. These findings support individualized monitoring, iodine testing, adherence checks, and coordinated antenatal endocrinology care to improve maternal and neonatal outcomes.
Conclusion: Following the diagnosis of hypothyroidism in early pregnancy, LT4 dosing should be tailored according to disease severity, prior history of hypothyroidism, TPO Ab status, and study location to ensure optimal maternal and fetal outcomes.

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: 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.
