Endocrine Abnormalities in Children With Traumatic Brain Injury at a Tertiary Care Center.

Objective Accidental traumatic brain injury (TBI) can lead to severe complications such as endocrine abnormalities and long-term morbidities and can negatively impact patient lives. These conditions are also associated with a high cost of treatment over a lifetime, a significant concern in low-to-middle-income countries (LMICs). In Pakistan, the prevalence of children with endocrine abnormalities secondary to TBI remains largely unexplored. We conducted a retrospective cross-sectional study to estimate the burden of endocrine abnormalities due to TBI among children in our population. Methods Twenty patients previously admitted with head injury between September and October 2019 were retrospectively reviewed with tests for baseline serum sodium, plasma osmolality, cortisol, adrenocorticotropin (ACTH), free thyroxine (fT4), growth hormone (GH), insulin growth factor-1 (IGF-1), follicle-stimulating hormone (FSH), luteinizing hormone (LH), thyroid-stimulating hormone (TSH), prolactin, estradiol, and testosterone. Data were collated from the electronic Health and Information Management System (HIMS) and analyzed using SPSS v25. Chi-square and t-tests were used to identify associations between variable groups. Outcomes of interest included correlations between hormonal levels and demographic factors, interventions and hormonal levels, and complication rates and hormonal levels. Results Our study reports three (15% of the total cohort) patients with pituitary hormone deficits (two with low IGF-1 and one with low TSH). High serum IGF-1 and ACTH levels were also observed in three (15%) children. High IGF-1 was associated with female gender (p=0.007), mechanical ventilation (p=0.038), and falls (p=0.028). IGF-1 (p=0.035) and GH (p=0.049) levels were associated with improvement in Extended Glasgow Outcome Scale (GOS-E) score. Testosterone was positively correlated with a high percentile for height (p=0.005) and GOS-E scores on follow-up (p=0.030). High testosterone levels (592.12 ± 102.28 ng/dl) were associated with good functional outcomes in post-pubescent patients (p<0.05). Serum fT4 was linked with a high GOS-E score at discharge in prepubescent patients (p=0.034). Neurosurgical decompression was the only risk factor for hormone deficiency, comprising 67% of the group with hormone deficiencies (p=0.028). The learning difficulties were observed exclusively in children with hormonal deficiencies (7 patients, p=0.000).  Conclusion Hormonal dysfunction due to TBI in children can lead to poor outcomes. High serum IGF-1, testosterone, and free T4 levels were associated with improved functional outcomes in children with TBI. Limited follow-up and resources in LMICs are significant barriers to addressing the morbidity associated with these conditions and need to be addressed at a health policy level.

The significance of MGMT methylation in Glioblastoma Multiforme prognosis.

Methylation of O6-methylguanine-DNA methyltransferase (MGMT) has been extensively studied as a biomarker in predicting the prognosis of patients with GBM (Glioblastoma multiforme). Its significance has been studied in various subgroups, including age, gender and even race. Correlation between prognosis with MGMT methylation and different treatment regimens has also been studied in detail. There are multiple techniques to analyze MGMT methylation in tumour specimen. We review the current evidence for the importance of MGMT methylation as a biomarker for prognosis in GBM patients, the techniques to analyze it and the effect of epidemiologic factors on its significance.

Depression in adult patients with primary brain tumours: a review of independent risk factors.

Depression is considered an under-diagnosed problem, especially in patients with malignancies. Patients with brain tumours in particular, have a relatively higher risk of developing depression, which is multifactorial. Herein, the authors review the recent literature on the prevalence of depression in patients with brain tumours, and explore the various risk factors involved. .
