Postoperative intensive care management and residual endocrinopathy of pediatric supratentorial brain tumors: a retrospective cohort study.

OBJECTIVES: Endocrinopathy can occur as a postoperative sequel in children treated for supratentorial tumors (STTs). We assessed prediction of a residual hypothalamic/pituitary insufficiency (HPI) in these patients and factors associated with prolonged length of hospital stay (LOS). METHODS: This is a retrospective cohort study of children who had surgery for STTs in two tertiary centers in Saudi Arabia (2009-2019). We assessed PICU postoperative management and risk of HPI. Data were analyzed using SPSS V24.0 and a logistic regression model for a prediction of a prolonged LOS. RESULTS: Data included 55 children (1-18 years, mean 9.5 ± 4.9 years) who required STT surgeries, 32 (54%) females. Craniopharyngioma (27.3%) was the commonest STTs and 20% of patients had initial symptoms of HPI. PICU management included the use of different types of intravenous fluids (IVFs) and medications such as steroids and desmopressin (DDAVP). An early postoperative DI was reported in 21.8% (n=12/55). Residual HPI included 24 (43.6%) presumed cortisol deficient and 18 (32.7%) central DI patients. Risk factors for postoperative HPI were female gender, age <6 years, headache and preoperative pituitary symptoms. LOS (Median=25.5 ± 12.2 days) was significantly prolonged in patients who required two or more doses of DDAVP [B=13; 95% CI= (1.7-24.3) days] and reduced in patients who had suspected preoperative HPI [B=-19.6; 95% CI= (-31.1, -8.2) days]. CONCLUSIONS: Prediction of postoperative HPI in pediatric STTs enhances an early initiation of treatment in PICU and reduces LOS. A meticulous use of IVF and medications supervised by a multidisciplinary team is essential for a favorable outcome.

Congenital hypothyroidism in Saudi population in two major cities: A retrospective study on prevalence and therapeutic outcomes.

OBJECTIVE: Congenital hypothyroidism (CH) is a common cause of preventable severe neurocognitive impairment in children. Previously conducted studies describing the natural history of CH in Saudi Arabia were either of shorter duration or a limited number of patients. In this study, we aim to assess our experience in the clinical course and therapeutic outcome of CH in two large tertiary centers in Saudi Arabia. METHODS: This is a retrospective chart review of patients <18 years of age diagnosed with CH at King Abdulaziz Medical City in Jeddah and Riyadh, Saudi Arabia, between 2000 and 2018. Data were collected from the patients' medical records, including epidemiological, clinical, laboratory, and radiological features as well as a long-term outcome of CH. Statistical analysis was carried out using the JMP statistical software. This study was approved by the Institutional Review Board (IRB) at King Abdullah International Medical Research Center (KAIMRC). RESULTS: Out of the 71 cases, 53.5% were female, and 80.3% of these cases were diagnosed in the 1st week of life. The estimated incidence of CH is 1:2470 in the two study centers. Ectopic thyroid (43%, n = 25/58), dyshormonogenesis (34.5%, n = 20/58), and thyroid agenesis and hypoplasia (22.4%, n = 13/58). Learning difficulty was significantly associated with delayed treatment onset (P = 0.044) and lower compliance with treatment (P = 0.001). CONCLUSION: In our study, the incidence of dyshormonogenesis in CH is higher than international rates (34.5% vs. 20%), possibly because of consanguinity. Effective neonatal screening program facilitates early diagnosis that leads to prompt management of CH and avoidance of long-term outcome of neurocognitive impairment.
