Paroxysmal autonomic instability syndrome with dystonia (PAISD) is a possible complication that worsens the prognosis of hypoxic-ischemic encephalopathy related to non-fatal drowning. There are case reports of hyperbaric oxygen (HBO2) therapy enhancing recovery in such cases. We report a case of a 5-year-old boy admitted to the Pediatric Intensive Care Unit after a non-fatal drowning. He was transferred under mechanical ventilation and sedation, with hemodynamic instability and hypothermia. On admission he had a Glasgow Coma Score of 6. On the fifth day of admission he presented episodes of dystonia with decerebration posture, diaphoresis, tachycardia and hypertension, sometimes with identified triggers, suggesting PAISD. The episodes were difficult to control; multiple drugs were needed. Electroencephalography showed diffuse slow wave activity, and cranioencephalic magnetic resonance imaging showed hypoxia-related lesions, suggesting hypoxic-ischemic encephalopathy. Early after admission the patient started physiotherapy combined with normobaric oxygen therapy. Subsequently he started HBO2 therapy at 2 atmospheres, with a total of 66 sessions. Dystonia progressively subsided, with gradual discontinuation of therapy. He also showed improvement in spasticity, non-verbal communication and cephalic control. This case highlights the diagnostic and therapeutic challenges of PAISD and the potential benefit of HBO2 therapy, even in the subacute phase, in recovery of hypoxic-ischemic encephalopathy.

Background: Tuberculosis disease under six years is an indicator of recent transmission within the community. We aim to characterize tuberculosis disease in children under six years in a pediatric department of a level II hospital in the Lisbon metropolitan area, which serves a high percentage of immigrants from Portuguese-speaking African countries. Methods: Retrospective and descriptive study of tuberculosis disease cases treated in our Department between January 2004 and December 2021 (18 years). Descriptive analysis of the collected data was performed using SPSS Statistics® 25. Results: 25 patients were included, 60% diagnosed between 2016 and 2021. Five patients were born in countries with high TB incidence and 11 other patients had immigrant families from such countries. Ten out of 13 patients not immunized with BCG had the recommendation to do so. A close contact with tuberculosis was known in 15 patients, and in seven of those the system for TB prevention failed. At diagnosis: 4/25 patients had disseminated tuberculosis (three miliary and one congenital). Conclusions: The increase in tuberculosis disease cases under six years in the last three years points to some pitfalls in tuberculosis surveillance and transmission prevention. New studies and institutional protocols are needed to improve the effectiveness of the network involved in TB prevention and treatment.

Objective: Assessment of changes in sleep habits at home in children during COVID-19 lockdown. 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. Comparison with a control sample from previous study (2019). Statistical analysis on SPSS Statistics23. Results: Two groups were compared: during lockdown (n=36, mean age 9.3 years-old) and before lockdown (n=48, mean age 8.8 years-old). 55.6% stated changes in sleep patterns. There was an increase in sleep hours, specifically in school-aged children (p=0.05) and adolescents (p=0.03), with no impact in global subjective sleep quality. Significative increase in screen hours (p=0.02) and its use after dinner (p=0.04). Discussion: Changes in sleep patterns during lockdown were frequent, alongside a higher use of screens. However, these did not affect the subjective sleep quality nor increased the occurrence of sleep disturbances.
