ORAL TOPICAL TIMOLOL MALEAT OR ORAL PROPRANOLOL TREATMENT FOR INFANTILE HEMANGIOMAS: CLINICAL ANALYSIS OF 403 PATIENTS

Objective: Infantile hemangiomas (IH) are the most common benign vascular tumors of infancy. Propranolol (P), a nonselective beta-blocker, has been successfully used in managing IHs. Ongoing studies investigate the efficacy of the topical β-antagonist timolol maleate (TM) in IHs. The aim of this study is to assess the effects of interventions for managing infantile hemangiomas in children. Material and Methods: We retrospectively reviewed a total of 403 IH patients from March 2021 to March 2022. The patients were stratified into three groups. Patients in Group 1 were given TM at a dose of one drop topically twice a day, 0.5%. Patients in Group 2 were given P at a dose of 1 mg/kg twice a day. The patients in Group 3 did not receive any treatment, and observation was conducted solely by contacting the controls. Results: The median age of diagnosis was 5 months (range 0-60), with 57.1% of the cases being male. While TM treatment was applied to 32% of the children and P treatment was applied to 46.9% of the children, no treatment was administered in 21.1%. The most common location of hemangiomas was the face, accounting for 39.2%. Hemangiomas were observed in more than one location in 48 (12%) children. The median follow-up period for the patients was 4 months (range 0-28). Hemangiomas remained unchanged in 28.3% of all cases, shrank in 60.3%, and continued to grow in 11.4%. The primary indication for initiating TM was superficial hemangiomas and infants younger than 6 months. The leading reason for starting P significantly higher than in the other groups (p:0.001). No statistically significant differences were observed between the groups regarding bleeding and ulceration rates (p>0.05). Conclusion: The efficacy of propranolol in treating IH was higher than that of TM

The Role of Anti-Neutrophil Antibodies in the Etiologic Classification of Childhood Neutropenia: A Cross-Sectional Study in a Tertiary Center

Infections, drugs, malignancies, immunodeficiency, and autoimmunity may cause neutropenia. In primary autoimmune neutropenia, anti-neutrophil antibodies (ANeuA) bind to membrane antigens of neutrophils, which give rise to peripheral destruction of neutrophils. However, it is not always easy to detect these antibodies. This study aims to investigate the etiology of neutropenia, and at the same time to evaluate the immune mechanisms by ANeuA testing using granulocyte indirect immunofluorescence test. In our study, 310 neutropenic patients who were between 3 months and 18 years of age were evaluated. ANeuA screening tests were performed in 108 neutropenic patients (group 1), and these patients were divided into 2 subgroups as persistent neutropenia (group 1P, n=12) and recovered neutropenia (group 1R, n=96). Besides, a control group in the same age range was formed, consisting of 39 non-neutropenic children (group 2). ANeuA serum levels were also checked in these groups, and no statistically significant difference could be found between groups 1 and 2, or between groups 1P and 1R, regarding ANeuA levels. As a conclusion, our study was the first comprehensive research in Turkey investigating the large-scale etiology of neutropenia. Moreover, while ANeuA screening tests did not provide sufficient insight for immune neutropenia, we argue that it is not necessary for routine use and that further research in the etiology of neutropenia is required
