Abstract
Background: Exposure to lead, damages vital organs and is now a global concern. Toxic effects of lead on the liver and thyroid gland have been mentioned previously, sometimes with conflicting results. Therefore, the present study aimed to assess changes in liver and thyroid function tests in patients with lead poisoning.
Methods: This case-control study was performed on 100 patients with clinical evidence of lead poisoning who were referred to Loghman-e-Hakim hospital in Tehran from April to December 2018. Also, another 100 participants with the matched sex and age, a history of opium use, and exposure to lead or non-work-related metals, and with normal lead levels, were considered as a control group. Demographic information was collected by a trained researcher by reviewing hospital records or interviewing participants. To monitor lead levels in the control group, 5 ml of venous blood was collected from the antecubital vein at 7 to 8 am in sterile tubes containing EDTA as an anticoagulant. Serum lead levels were assessed by GBC Avanta atomic absorption spectrophotometer. Values in the two groups were compared. SPSS version 16 (SPSS Inc. Chicago, Il, The USA) was used for data analysis. A P-value below 0.05 was considered statistically significant.
Results: The mean level of serum lead in case and control groups were 63.0±12.4 μg/dL and 6.0±2.1 μg/dL, respectively with a statistically significant difference (p<0.001). However, Alkaline phosphatase (ALKp), aspartate aminotransferase (AST) and alanine aminotransferase (ALT) enzymes were significantly higher in cases compared to controls (p<0.001). The thyroid-stimulating hormone in patients with lead poisoning (0.3±0.04 MIU/L) was significantly lower than those in the control group (2.5±1.23) (P=0.04).
Conclusion: Lead poisoning could potentially damage liver function and elevate liver enzymes. Moreover, it can also affect the levels of TSH and levothyroxine. Understanding the exact mechanisms might help to control The hepatotoxic effects of lead in patients. Also, knowing the pattern of elevated liver enzymes and thyroid hormones changes might help discriminate lead poisoning with other differential diagnoses.

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