Candida ciferrii, which is known as an agent of superficial yeast infection and onychomycosis, has rarely been isolated as an agent of candidemia. Limited reports have suggested different patterns of antifungal sensitivity. We report a rare candidemia case caused by c.ciferrii in an 8-year-old child in which isolated candida species were resistant to amphotericin-B (MIC > 1 μg/ml), fluconazole, (MIC ≥ 64 μg/ml), caspofungin (MIC ≥ 32 μg/ml), and anidulafungin (MIC ≥ 32 μg/ml) but sensitive to voriconazole (MIC ≤ 0.12 μg/ml). As far as we aware, this was the first recorded C. ciferrii candidemia case in children.

Acute disseminated encephalomyelitis (ADEM) is an acute demyelinating infection of the CNS that is characterized by multifocal white matter involvement often following an infection and vaccination. A 16-year-old child receiving risperidone for 7 years for the treatment of attention-deficit/hyperactivity disorder was hospitalized with complaints of double-vision during the past month and weakness on his right side, ataxia, and vomiting over the past 3 days. The child was diagnosed with ADEM after clinical, laboratory, and cranial MRI was conducted. Following an initial 3-day therapy with pulsed methylprednisolone, the child showed obvious clinical improvement. The treatment was continued with prednisolone and significant improvement was achieved. Enterovirus was detected in the results of the viral examination of the CSF. This child was found to be an interesting case having been diagnosed with ADEM associated with enteroviral infection, because of the rarity of few case reports in the literature.

Pneumomediastinum is defined as free air or other gases contained within the mediastinum. In children it is an uncommon clinical condition with good prognosis. It most frequently occurs with exacerbations of asthma but also may occur after cough, vomiting, excessive valsalva maneuver and after the first wheezing attack as well. The first-line treatment for pneumomediastinum is to relieve the inciting factor. Otherwise, no specific therapy is recommended for uncomplicated cases, three boys, with the ages of 4, 8 and 13, presented in the emergency department, each after a few days of shortness of breath and respiratory distress. Chest radiography revealed pneumomediastinum and subcutaneous emphysema which had occured after severe asthmatic attacks. All of these patients have improved spontaneously with conservative treatment.

An offspring of marriage between two first cousins presented with atonic seizures developed on the 20(th) day of life. The physical examination of the case was normal. In laboratory results, Ca(+2) level was 5.7 mg/dl, Mg(+2): 0.4 mg/dl (1,3-2,1), PTH: 28.4 pg/ml (12-92), and P-: 4.5 mg/dl. The case was diagnosed as hypomagnesemia with secondary hypocalcemia (HSH) and TRPM6 gene mutation analysis revealed a homozygote mutation of E157X.

We investigated the efficacy of a combination of ketamine and midazolam, comparing intravenous, oral, and rectal administrations for invasive procedures in children with malignancy. Seventy-three children under 5 years of age, who were scheduled for invasive procedure, were assigned to one of three groups: IV group (n = 25), ketamine 1 mg/kg and midazolam 0.05-0.1 mg/kg were given intravenously; PO group (n = 24), ketamine 3 mg/kg and midazolam 0.5 mg/kg were given orally; and PR group (n = 24), ketamine 3 mg/kg and midazolam 0.5 mg/kg given rectally. Vital signs including blood pressure, pulse rate, respiratory rate, and oxygen saturation were monitored, and patients were observed for side-effects. Optimal sedation (drowsy and asleep) was provided in 78 per cent of all patients and no statistical difference was observed among the three groups. No severe complications were observed in all groups. Recovery time from sedation was significantly longer in the intravenous group (>120 min in two patients). Hallucination was noted in three (12 per cent) patients given intravenous medication, but not in those given oral or rectal medications. It is concluded that intravenous, oral, and rectal midazolam/ketamine are equally effective for invasive procedures in children with malignancy. The use of intravenous ketamine/midazolam may produce prolonged sedation and psychedelic effects in children. These adverse effects may alter the child's comfort and parental satisfaction.
