ABSTRACT
An 11-year-old boy with attention deficit/hyperactivity disorder (ADHD) presented with visual hallucinations several years after starting methylphenidate (MPH). The hallucinations resolved upon discontinuation of the drug. Reports of toxic hallucinosis during treatment with MPH are rare. Although the pathogenetic mechanism is unclear, the occurrence of hallucinations may be explained by a chronic increase in synaptic dopamine. Clinicians should be aware of this possible rare adverse manifestation occurring at therapeutic doses.

Early-onset infection findings caused by Group B Streptococcus occur within 24 hours of birth (60 per cent of cases) but they may appear anytime during the first 5 days of life. In our experience early-onset infection affects both preterm and term neonates. The Authors report the usual clinical signs described for bacterial infections. Unusual findings are also reported: among 34 infants with early-onset infection, the congenital diaphragmatic hernia was associated with GBS septicemia in two neonates; beads of perspiration were the first only clinical finding in one neonate too. Two cases of late-onset infection are also reported.
