The mean pain score during non-contact navigated laser retinopexy was 0.9±0.5. No complications associated with laser treatment were observed. Non-contact navigated laser retinopexy performed with the Navilas 577s navigated laser system is a safe and well-tolerated procedure with effectiveness comparable to conventional laser retinopexy.

Chronic granulomatous disease (CGD) is a rare primary immunodeficiency. Infections of lung, skin, lymph nodes, and liver are the hallmark of CGD and frequently the initial manifestation of the disease. The aim of the present paper is to describe the sites of infections and their causative agents in 38 pediatric patients with CGD. This retrospective, single-center cohort study included CGD patients followed at the allergy and immunology unit of a tertiary hospital in São Paulo, Brazil over the last 40 years. Sites of infections and their causative agents were described. Thirty-eight patients were included (36 males). The median age of onset of symptoms was 45 days (ranging from 7 days-7 years), and the median age at diagnosis was 23 months (ranging from 1 month-12 years). In all, 31.6% of the patients reported a family history of child deaths and 21% (eight cases) had another male family member with CGD. The most common infections were pneumonia (81.6%), skin infections (50.0%), adenitis (42.1%), and liver abscess (23.7%); 188 cultures were positive (85.6% bacteria; 14.4% fungi). The most prevalent bacterial agents were Staphylococcus sp. (12.4%), Staphylococcus aureus (11.2%), and Klebsiella pneumoniae (9.3%). Aspergillus sp. and Candida sp. were 56% and 22.2% of the i
