  • Congenital candidiasis – a diagnostic challenge
    Publication . Rolim, Sara; Figueirinha, Joana; Miguel, Cristina; Lopes, Susana; Rocha, Felisbela; Martins, Cecília; Carvalho, Sónia
    Introduction: Congenital candidiasis is a rare intrauterine infection characterized by vesicular and pustular skin lesions appearing in the first six days of life. Clinical case: The authors describe the case of a full-term infant presenting erythematous macules, vesicles and pustules involving the trunk and extremities and cervical burn-like dermatitis at birth. Mycological skin lesion culture was positive for Candida albicans. Blood culture was positive for methicillin-sensitive Staphylococcus aureus. After systemic antifungal and antibiotic therapy was started, the newborn remained asymptomatic with lesion improvement. Discussion/ Conclusion: Herein is reported a case of congenital candidiasis in a full-term infant, with a successful recovery. The rarity of congenital candidiasis can lead to delayed diagnosis and unnecessary treatment. This case shows that fungal infection should be considered in the differential diagnosis of vesiculopustular skin lesions in neonates. Systemic therapy should be initiated if invasive candidiasis is suspected.

    Background: High resolution genome-wide copy number analysis, routinely used in clinical diagnosis for several years, retrieves new and extremely rare copy number variations (CNVs) that provide novel candidate genes contributing to disease etiology. The aim of this work was to identify novel genetic causes of neurodevelopmental disease, inferred from CNVs detected by array comparative hybridization (aCGH), in a cohort of 325 Portuguese patients with intellectual disability (ID). Results: We have detected CNVs in 30.1% of the patients, of which 5.2% corresponded to novel likely pathogenic CNVs. For these 11 rare CNVs (which encompass novel ID candidate genes), we identified those most likely to be relevant, and established genotype-phenotype correlations based on detailed clinical assessment. In the case of duplications, we performed expression analysis to assess the impact of the rearrangement. Interestingly, these novel candidate genes belong to known ID-related pathways. Within the 8% of patients with CNVs in known pathogenic loci, the majority had a clinical presentation fitting the phenotype(s) described in the literature, with a few interesting exceptions that are discussed. Conclusions: Identification of such rare CNVs (some of which reported for the first time in ID patients/families) contributes to our understanding of the etiology of ID and for the ever-improving diagnosis of this group of patients.
