Nocardia farcinica complicating Cogan's syndrome.

Nocardiosis is an uncommon bacterial gram-positive infection caused by aerobic actinomycetes in the genus Nocardia. Nocardiosis is typically regarded as an opportunistic infection with approximately two-thirds of infected patients being immunocompromised. In this case report we describe a 45-year-old female who presented with a right thigh abscess. She had been taking high-dose prednisolone and ciclosporin for Cogan's syndrome. She presented with erythema and severe pain over her right thigh. Ultrasound showed a collection and Nocardia farcinica was isolated. This case report stresses the importance of considering atypical infections in immunocompromised patients, even with minor symptoms, to avoid delay in diagnosis and treatment.

Report of neonatal meningitis due to Salmonella enterica serotype Agona and review of breast milk-associated neonatal Salmonella infections.

We present the first documented case of Salmonella enterica serotype Agona meningitis in a 6-day-old baby. S. enterica serotype Agona was isolated concurrently from infant cerebrospinal fluid and parental fecal samples, and Salmonella was isolated from breast milk. The role of breast milk in transmission of Salmonella enterica is discussed.
