The aim of this study was to characterize the acute complications that required hospitalization in children under 5 years with Sickle Cell Disease. The population included 70 patients, 64% of African ascendency and 95.7% homozygotic for the HbS.

Methods: Retrospective, transversal study in a pediatric ward of a level II hospital. Questionnaires concerning sleep quality, patterns and its modifications during lockdown were distributed from June to August 2020.
Objectives: Given that 30%-50% of children with trisomy 21 have persistent obstructive sleep apnoea (OSA) after adenotonsillectomy, we evaluated whether demographic, clinical and polysomnographic factors predicted persistent OSA and OSA severity after adenotonsillectomy.
Design: Retrospective study.
Setting: Secondary care hospital.
Drug-Induced Sleep Endoscopy in Pediatric Obstructive Sleep Apnea.
Otolaryngol Head Neck Surg
February 2021
Objective: To describe drug-induced sleep endoscopy (DISE) findings in children with obstructive sleep apnea and to differentiate them between surgically naïve children and children who had adenotonsillectomy performed.
Study Design: Retrospective case series with chart review.
Setting: Secondary care hospital.
Objective: Overweight seems to be related to a higher prevalence of sleep disturbances. Decreased sleep duration and altered sleep quality are risk factors for obesity. Our aim was to compare the sleep pattern of overweight children with that of a matched control group and assess the relationship between sleep quality and obesity.

- Sleep disorders in children are often overlooked, with factors like socio-cultural environment and medical conditions impacting sleep quality and leading to physical and social issues.
- A study of pediatric patients at a Primary Health Care Center in Lisbon found that 59.4% of children scored above the threshold for sleep disorders, with children from single-parent families experiencing higher prevalence, especially in cases of parasomnia.
- Children diagnosed with sleep-disordered breathing reported increased daytime sleepiness, highlighting the importance of family structure on sleep habits and its potential effects on daily functioning.
Article Synopsis
- Hypercalcemia is a serious and rare metabolic disorder in children that can be life-threatening and has various potential causes, including cancer.
- A case is reported of a 3-year-old boy who exhibited severe symptoms and was found to have extremely high calcium levels and anemia, leading to his admission to intensive care.
- After treatment involving hydration, specialized filtration, and the use of zoledronate, the child was diagnosed with acute lymphoblastic leukemia, highlighting that hypercalcemia may indicate underlying malignancy in pediatric patients.
Objectives: To study the effect of two intravenous maintenance fluids on plasma sodium (Na), and acid-base balance in pediatric intensive care patients during the first 24h of hospitalization.
Methods: A prospective randomized controlled study was performed, which allocated 233 patients to groups: (A) NaCl 0.9% or (B) NaCl 0.
Background: Children and adolescents with sickle cell disease (SCD) have a higher incidence of sleep pathology and obstructive sleep apnea syndrome (OSAS). The nocturnal hypoxemia is a risk to vaso-occlusive crisis among other SCD morbidities. Our aim was to compare polysomnography (PSG) results in a sample of children with SCD with a sample of children with suspected OSAS without SCD.
