Tuberous sclerosis complex (TSC) is a genetic neurocutaneous disorder characterised by seizures, mental retardation and hamartoma formation in multiple organs, mainly in the brain, skin, kidney, liver, lung and heart. Renal manifestations occur in about 60–80% of all patients with TSC and their rate increases with age. We report the case of a 17-year-old boy with tuberous sclerosis who presented with abdominal pain associated with kidney failure. Investigation revealed bilateral renal lesions, suggesting angiomyolipomas. On further work-up, malignancy was suspected and the patient underwent bilateral partial nephrectomy with histological diagnosis of bilateral renal cell carcinoma. This is a rare complication of TSC, particularly in a paediatric setting. Adequate surveillance of kidney disorders in patients with TSC is warranted, to guarantee an early diagnosis and treatment.
The COVID-19 pandemic brought unexpected effects on healthcare systems access and usage. Some of the measures implemented by governments to try and contain it, such as confinement periods, social distancing, widespread use of masks and other hygiene practices led to unprecedented epidemiological changes in several common infectious diseases.We describe changes in antibiotic prescribing in pediatric outpatients before and during the pandemic in a dynamic population analysis context during a study period of three years in mainland Portugal.There was a marked reduction in antimicrobial prescribing in all regions, particularly in younger children and during the lockdown periods.This reduction was much sharper for those antimicrobials most commonly used to treat respiratory-tract infections, as Amoxicillin (with and without β-lactamase inhibitor) and Macrolides, and considerable less accentuated in other commonly prescribed antibiotics as Co-Trimoxazole and Fosfomycin, usually associated with the treatment of urinary tract infections.Conclusion: Our findings indicate that the COVID-19 pandemic has had profound effects on antibiotic use in ambulatory care in children in Portugal.Further monitoring is necessary to ascertain whether this reduction in antibiotic prescription will persist and whether these changes may impact antimicrobial resistance.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
