RESUMEN
As hypocalcemia is uncommon, serum calcium levels are not routinely measured in many emergency medicine clinics. We report a case of an adolescent girl with a transient loss of consciousness due to hypocalcemia. A 13-year-old healthy girl had a syncopal episode complicated with numbness in the extremities. On admission, she was fully conscious, but hypocalcemia and QT prolongation were noted. After careful consideration of the possible etiologies, the patient was diagnosed with acquired QT prolongation due to primary hypoparathyroidism. The patient's serum calcium levels were controlled by activated vitamin D and calcium supplementation. Primary hypoparathyroidism-associated hypocalcemia can cause QT prolongation and neurological complications, even in previously healthy adolescents.
RESUMEN
Varicella-zoster virus (VZV) may cause aseptic meningitis in the pediatric age group. We describe a pediatric case of aseptic meningitis with a substantial increase of the paired serum antibody to VZV in which the child did not have skin rash during the course of illness. The patient was a 13-year-old boy without any history of exposure to VZV who was admitted with headache, vomiting, and low-grade fever. He had received one dose of varicella vaccine derived from the Oka/Biken strain (vOka) at the age of one year. Cerebrospinal fluid (CSF) analysis on admission revealed an elevated white blood cell count at 609/mm3 with 99.6% mononuclear cells. As his symptoms resolved after lumbar puncture alone, he was discharged on the seventh day of hospitalization without receiving any specific medication. Serum VZV-IgG titer was found to be substantially elevated after two weeks. VZV infection and reactivations associated with vaccination, as well as past infections, should be included in the differential diagnoses of pediatric aseptic meningitis, even in the absence of skin rash in the entire course. Polymerase chain reaction (PCR) testing for VZV DNA in CSF should be performed in all cases, if available.
RESUMEN
Influenza is a concerning disease in terms of risk management for cruise passengers during a voyage. Currently, cruise passengers include children in addition to elderly people. Oral oseltamivir can be used to treat pediatric influenza. In addition, early antiviral treatment may reduce the spread of influenza on board. However, the capsule form of oseltamivir is not of the recommended dosage for children. In this report, we describe 2 siblings who acquired influenza during travel on a world cruise ship and were treated with decapsulated oseltamivir. The siblings' mother was instructed to decapsulate a 75 mg oseltamivir capsule, suspend the powder in 15 mL of water (5 mg·mL-1), stir well, and administer the required amount of medicine orally to each patient using a syringe. Both patients recovered successfully with no complications. The presented case suggests that suspending decapsulated oseltamivir in water and measuring the required amount with a syringe for orally administration to children with influenza can be a safe treatment strategy in resource-limited settings.
