Elizabethkingia meningosepticum infections with varied presentations and different antimicrobial susceptibility - A case series.

We report three sporadic infections by Elizabethkingia meningosepticum from Government Medical College Kozhikode in Kerala state, South India over a period of three years. Two cases were commenced in the community in immunocompromised children beyond the newborn period, but both recovered promptly. Another was a hospital-acquired meningitis in a newborn baby who developed neurologic sequelae. In contrast to widespread antimicrobial resistance exhibited by this pathogen, there was good susceptibility to commonly used antimicrobials such as ampicillin, cefotaxime, piperacillin, ciprofloxacin, and vancomycin. Whilst ß lactam antibiotics are found effective in the treatment of Elizabethkingia septicaemia of children, piperacillin-tazobactam, vancomycin combination seems effective empiric choice of antibiotics for neonatal meningitis due to Elizabethkingia; there is a need for guidelines for the management of this infection, especially in neonatal meningitis.

Pseudotumour cerebri due to phenytoin in a child.

Pseudotumour cerebri is a manifestation of intracranial hypertension in an otherwise normal individual. We hereby report phenytoin-induced pseudotumour cerebri in a 9-year-old boy who received phenytoin as a prophylactic anticonvulsant following surgical removal of unifocal Langerhans cell histiocytosis involving the right frontal bone. The child was evaluated for headache and diplopia after starting phenytoin and on evaluation was found to have bilateral sixth nerve palsy. The only abnormality detected was an elevated cerebrospinal fluid pressure. Withdrawal of phenytoin resulted in complete resolution of symptoms. Despite meticulous literature search, we found only 1 other report of phenytoin induced pseudotumour cerebri. We report this case to highlight the need to consider this entity whenever a patient presents with new onset or persistent headache and visual symptoms soon after starting a medication since a high degree of suspicion is needed to arrive at the diagnosis and to take appropriate steps before it progresses to harmful complications such as vision loss.
