ABSTRACT

The purpose of the study is to describe the experience of a multidisciplinary team in a tertiary hospital regarding the management of Infantile Hemangiomas (IH). The method employed is a retrospective analysis of patients with IH followed in a tertiary pediatric hospital between January 2010 and May 2022. A total of 393 IH were diagnosed (56.7% female), with a median age of 5 months (interquartile range (IQR), 3-10). Imaging investigation was necessary for diagnosis and for exclusion of other IH in 9.2% and 14.3%, respectively. Focal (74.0%) and superficial (59.7%) lesions were more frequent as was facial location (35.9%). Pre-treatment ulceration or hemorrhage occurred in 6.6%. At follow-up, 87.4% regressed partially and 12.6% completely; 2.7% relapsed. Propranolol was started in 30.0% of cases for a median period of 9 months (IQR, 6-12), mainly due to esthetic concerns (41.9%). Side effects occurred in 8.3% (sleep disturbance in 5.1%). Only 1.7% were refractory and 5.9% had a rebound effect. Eleven patients were treated with topical timolol and 41 underwent surgery. Patients that were treated with propranolol had more risk factors (p = 0.016) and presented deeper lesions (p < 0.001) with a larger diameter (p < 0.001); total IH regression was less frequent (p < 0.001). Since 2020, twice-daily dosage was more frequently prescribed than three times daily (p = 0.007) and inpatient initiation of propranolol decreased (p = 0.750), without significant difference in the incidence of adverse reactions, duration of treatment, and lesion evolution.  Conclusions: Our protocol proved to be safe and feasible in an outpatient setting and twice daily administration of propranolol was effective. The majority of IH showed at least partial regression. Early detection of high-risk IH is paramount and a multidisciplinary assessment by a specialized team is essential for adequate management. What is Known: • IH are the most common vascular tumors in childhood. Although the majority evolves favorably, treatment may be warranted in selected cases. • Early detection of high-risk IH is paramount, and a multidisciplinary assessment by a specialized team is essential for adequate management. What is New: • One-third of our sample was treated with propranolol. These patients had more risk factors and presented deeper lesions with a larger diameter, and tumor total regression was less frequent. • Our results reinforce safety and feasibility of propranolol initiation in an outpatient setting, including twice daily dosage.

ABSTRACT

Primary mitochondrial disorders are highly variable in clinical presentation, biochemistry, and molecular etiology. Mitochondrial disorders can be caused by genetic defects in the mitochondrial, in nuclear genome, or in the interplay between the two genomes. Biochemical screening tests may be inconclusive or misleading since patients, with confirmed mitochondrial disorders specially in pediatric age, may exhibit normal routine biochemistry, muscle histology, or enzymatic analysis of the mitochondrial respiratory chain. Diagnosis is often challenging even with combination of multiple criteria (clinical, biochemical, histological, and functional), as innumerous conditions cause secondary mitochondrial dysfunction. Nowadays, a definite diagnosis is only possible by genetic confirmation since no single score system is satisfactorily accurate, being sensitive but not specific.Conclusion: Awareness between physicians is of major importance considering that clinical suspicion may not be obvious regarding the heterogenicity in presentation and biochemical features of mitochondrial disorders. In this review, we provide information on diagnosis approach to patients suspected for mitochondrial disorders as well as management on chronic and acute settings. Follow-up should provide comprehensive information on patient's status, since intervention on these diseases is mostly supportive and prognosis is variable and sometimes unpredictable. What is Known: • Mitochondrial disorders are heterogenous and may present at any age, with any symptoms and any type of inheritance. • Mitochondrial disorders may be due to pathogenic variants in mitochondrial DNA (mtDNA) or nuclear genes (nDNA). What is New: • Since no single score system is satisfactorily accurate, a definite diagnosis is only possible with genetic studies with gene panels proving to be a cost-effective approach. • Clinical and biochemical features of patients without a confirmed diagnosis must be reviewed and other diagnosis must be considered. A wider genetic approach may be applied (WES or WGS).
