The impact of the coronavirus disease 2019 pandemic on pediatric hospitalization in Kitami, Japan.

BACKGROUND: Coronavirus disease 2019 (COVID-19) has drastically changed the recommended activities and environment for patients worldwide. Our aim was to assess the impact of COVID-19 on pediatric hospitalizations in Kitami, Japan. METHODS: A retrospective, single-center study was conducted on hospitalized patients aged 0-14 years at the Japanese Red Cross Kitami Hospital. We compared the incidence of pediatric patients hospitalized in 2020 with those in 2017-2019. RESULTS: The number of pediatric hospitalized patients dropped significantly in 2020 compared to that in 2017-2019 (median 43.0 vs 78.5 per month, P < 0.001). The patients were significantly older in 2020 (4.3 vs 3.4 years, P < 0.001). Hospitalization from respiratory (8.5 vs 30.5, P < 0.001) and gastrointestinal infections (3.0 vs 6.0, P = 0.004) significantly decreased. Admission due to respiratory syncytial virus (0.0 vs 4.0, P < 0.001), human metapneumovirus (0.0 vs 1.0, P = 0.005), influenza (0.0 vs 0.0, P = 0.009), adenovirus (0.0 vs 1.0, P = 0.003), and rotavirus infection (0.0 vs 0.0, P = 0.025) also decreased significantly. The <1-5 age groups significantly decreased (<1 year old, 6.5 vs 12.5, P < 0.001; 1-3 years old, 13.0 vs 29.5, P < 0.001; 4-5 years old, 5.5 vs 11.5, P < 0.001). Hospitalization due to foreign body ingestions increased significantly in 2020 (1.0 vs 0.0, P = 0.010). CONCLUSIONS: The COVID-19 control measures inadvertently reduced the number of hospitalized pediatric patients, especially younger children with respiratory and gastrointestinal infections.

Diagnostic dilemma in a case of obstructive sleep apnoea syndrome with reversible pulmonary hypertension and right heart failure: A case report.

Childhood obstructive sleep apnoea syndrome (OSAS) secondary to adenoid hyperplasia is known to give rise to pulmonary hypertension. However, we present a case of a toddler with pulmonary hypertension (PH) and right heart failure due to OSAS, the cause of which is difficult to identify. After the patient underwent an adenotonsillectomy, OSAS disappeared and the PH eventually resolved. Both paediatricians and otolaryngologists should know that paediatric OSAS can occur even in the setting of mild, clinically insignificant palatine tonsil hypertrophy and adenoid hyperplasia. Surgical intervention should be considered without losing the opportunity if it could be the cause of PH.
