BackgroundThe aims of this study were to identify the source and the transmission pathway for a Staphylococcal Scalded Skin Syndrome (SSSS) outbreak in a maternity setting in Italy over 2 months, during 2014; to implement appropriate control measures in order to prevent the epidemic spread within the maternity ward; and to identify the Methicillin-Resistant Staphylococcus aureus (MRSA) epidemic clone.MethodsEpidemiological and microbiological investigations, based on phenotyping and genotyping methods, were performed. All neonates involved in the outbreak underwent clinical and microbiological investigations to detect the cause of illness. Parents and healthcare workers were screened for Staphylococcus aureus to identify asymptomatic carriers.ResultsThe SSSS outbreak was due to the cross-transmission of a rare clone of ST5-CA-MRSA-SCCmecV-spa type t311, exfoliative toxin A-producer, isolated from three neonates, one mother (from her nose and from dermatological lesions due to pre-existing hand eczema) and from a nurse (colonized in her nose by this microorganism). The epidemiological and microbiological investigation confirmed these as two potential carriers.ConclusionsA rapid containment of these infections was obtained only after implementation of robust swabbing of mothers and healthcare workers. The use of molecular methodologies for typing was able to identify all carriers and to trace the transmission.
A newborn girl of 36 weeks gestation was noted to have several anomalies, including bilateral low ear attachment with ear pinnae hypertrichosis, left preauricular pit, micrognathia, short lingual frenulum, and short neck. Pregnancy history revealed poorly controlled maternal gestational diabetes (GD). Localized hypertrichosis of the ear pinnae may represent a potential marker of GD and thereby alert physicians to suspect other potentially GD-associated conditions such as macrosomia, asphyxia, respiratory distress, hypoglycemia, hypocalcemia, hyperbilirubinemia, polycythemia, hypertrophic cardiomyopathy, and congenital anomalies, particularly those involving the central nervous system.
Neonatal diabetes mellitus (NDM) is a rare condition characterized by onset of persistent hyperglycaemia with-in the first six months of life. Heterozygous mutations in KCNJ11 gene account for about half of the cases of per-manent form of NDM and are associated with a wide range of neurocognitive disabilities. In suspected NDM, immediate molecular genetic testing is recommended because most of the cases due to mutations in KCNJ11 gene are responsive to oral sulfonylurea (SU) therapy with excellent glycaemic control at long term follow up. The present report describes a case of early detection of permanent NDM, due to KCNJ11 gene mutation, which has been successfully treated with SU oral therapy.
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.
