Evaluation of pituitary function in cases with the diagnosis of pediatric mild traumatic brain injury: Cross-sectional study

ABSTRACT Background: This study was to determine whether pituitary dysfunction occurs after head trauma in children or not and which axis is affected more; to define the association of pituitary dysfunction with the severity of head trauma and duration time after the diagnosis of head trauma. Materials and Methods: In this study, 24 children who were diagnosed with head trauma were evaluated regarding pituitary dysfunction. In all cases, after 12 h fasting, serum cortisol, fT3, fT4, thyroid-stimulating hormone, prolactin, insulin-like growth factor-1, serum sodium, urine density, follicle-stimulating hormone, luteinizing hormone, in female cases E2, in male cases, TT levels were determined. Results: Mean age of children was 9.5 ± 3.1 years, 14 children (58.3%) had mild, 9 children (37.5%) had moderate, and 1 children (4.2%) had severe head trauma according to the Glasgow coma scale. Mean duration time after head trauma was 29.4 ± 9.8 months. In all cases, no pathologic condition was determined in the pituitary hormonal axis. In one children (4.2%), low basal cortisol level was found. There were no children with hormonal deficiency in this study. Conclusion: Although pituitary dysfunction after head trauma may develop in the early period, some may present in the late period; therefore, all cases should be followed up at outpatient clinics for a longer period.

Purpose: To study the relationship between the levels of serum thyroid-stimulating hormone (TSH)-receptor autoantibodies (TRAbs) and thyroid eye disease (TED) activity and severity scores.Methods: A cross-sectional study was performed. The medical records of 315 patients diagnosed with TED between March 2014 and December 2019 were reviewed. The clinical activity score (CAS) was used to assess TED activity and a modified NOSPECS score was used for severity grading. The serum TRAb level was measured using two assays: a TSHR binding inhibitory immunoglobulin (TBII) assay and thyroid stimulating immunoglobulin (TSI) bioassay.Results: The TBII and TSI assay results were significantly positively correlated with the CAS (R = 0.113 and 0.211, respectively; p < 0.05), modified NOSPECS score (R = 0.173 and 0.316, respectively; p < 0.05), and proptosis (R = 0.136 and 0.167, respectively; p < 0.05). Both assays demonstrated significant differences in the level of TRAb between patients with and without compressive optic neuropathy or corneal epithelial defects.Conclusions: The levels of TRAbs according to both TBII and TSI assays showed significant correlations with clinical signs of corneal involvement, optic neuropathy, and TED activity and severity.

Objective: To identify effect of pre-analytical variables on serum thyroid stimulating hormone. Study Design: Cross sectional study. Place and Duration of Study: Armed Forces Institute of Pathology (AFIP) Rawalpindi, Department of Chemical Pathology & Endocrinology, from Mar 2018 to Aug 2018. Methodology: Hundred subjects with ages ranging from 18 to 34 years, irrespective of gender, were randomly selected for this study. Five milliliters venous blood sample was collected from each subject in a serum separator and divided into two aliquots. First aliquot was centrifuged and analyzed immediately for TSH, while second aliquot was stored for 24 hours and was then analyzed. TSH was measured by third generation assay usingchemiluminescence technique on ADVIA Centaur® XP. Serum TSH levels were also analyzed twice daily; in the morning (0800 to 0900 hours) and afternoon (1400 to 1600 hours). Data was analyzed using SPSS version 24. Frequency and percentages were calculated for qualitative variables like gender and pre-analytical variables. Test of significance Mann-Whitney U-test was applied and p-value <0.05 was taken as significant. Results: Mean age of subjects was 23 ± 3.4 years. Change in circadian rhythm was observed in 17 (28%) males and 14 (36%) females. Statistically significant association was found between morning and evening TSH levels, while no change was observed in TSH level by early and late centrifugation of samples. Conclusion: TSH levels vary significantly between blood samples collected at different timings of the day from the same person. TSH is resistant to degradation, immunologically stable, and reasonably insensitive to potential problems associated with routine specimen handling, when measured by immunoassay technique. Therefore, it is helpful in large epidemiological studies and small size laboratory, which require long transportation time and storage.
