Bloodstream infections due to Trichosporon species in paediatric patients: Results from the first national study from Turkey.

BACKGROUND: Invasive Trichosporon infections are rarely seen opportunistic fungal infections in children and mainly affect immunocompromised patients. This multicenter retrospective study has rewieved the characteristics, risk factors, treatment modalities and outcomes of bloodstream infections caused by Trichosporon species in children diagnosed over the past ten years in Turkey. METHODS: The study was performed with the participation of 12 of 55 hospitals invited from Turkey. In each center, the patients with bloodstream infections caused by Trichosporon spp. between January 2010 and December 2020 were retrospectively ascertained and the results were reported to the study coordinator by means of a simple case report. Data were collected on patient demographics, underlying condition(s), treatment of.infections caused by Trichosporon spp, and 7 and 30- day mortality rates. RESULTS: A total of 28 cases with fungemia caused by Trichosporon spp. were included in the study. The most common underlying disease was paediatric cancers (39.3%). T. asahii infections were detected in 78.5 % (n=22) of patients. A various spectrum of antifungal treatment regimens were used including intravenous amphotericin B monotherapy in 35.7%, intravenous amphotericin B and voriconazole combination in 32.1% and intravenous voriconazole monotherapy in 28.6% of the patients. The overall mortality rate was 28.5 %. The mortality rates were 12.5% in the voricanozole, 30% in the amphotericin B and 33.3% in combined voriconazole -amphotericin B arms CONCLUSIONS: Invasive Trichosporon infections with an important impact of patients quality of life are almost related to underlying diseases with an overall mortality rate of 28.5%. Voriconazole was found to be associated with lower mortality rates when compared with other treatment regimens.

Pediatric subdural empyema as a complication of meningitis: could CSF protein/CSF glucose ratio be used to screen for subdural empyema?

Subdural empyema (SDE) is a rare condition which can appear secondary to meningitis in childhood, especially in infants. This study was planned to evaluate and compare clinical and laboratory features, treatment, and outcome of children with SDE to those with acute bacterial meningitis (ABM) without SDE. The electronic medical files of 266 patients diagnosed with ABM between January 2009 and December 2019 were evaluated. Patients' demographic and clinical features, laboratory results, cranial imaging findings, treatment, and outcomes were recorded. SDE was identified in 10 patients, 3.7% of all diagnosed with meningitis. The etiology of SDE was identified in eight (80%). The most common responsible pathogen was Streptococcus pneumoniae. Cranial imaging was performed between the 2nd and 13th days of admission, and the most common reason of performing cranial imaging was persistence of fever. Two patients were healed with 4-6 weeks of antibiotic treatment without surgery, eight (80%) needed surgical intervention.Conclusion: The clinical signs and symptoms of SDE may be subtle. If the fever persists or focal neurological findings are seen during the treatment of bacterial meningitis, SDE should be suspected. Furthermore, patients with ABM who are determined to have a protein-to-glucose ratio in the cerebrospinal fluid above 4.65 should be carefully monitored for SDE development. What is known: • Subdural empyema may develop subsequently to meningitis, especially in the infant age group in whom very little is known in terms of disease characteristics. • Delay in diagnosis and treatment can cause long-term neurologic sequelae and mortality. What is new: • Persistence or relapse of fever during the treatment of acute meningitis is an important warning sign for SDE even if there are no other symptoms. • Children with subdural empyema secondary to bacterial meningitis have higher protein-to-glucose ratio in the CSF, and a threshold of ˃ 4.65 was determined to demonstrate 100% sensitivity and 50.7% specificity.

[Coexistence of Pulmonary Hydatid Cyst and Mycoplasma pneumoniae Pnömonia in a Child]. / Akciger Kist Hidatigine Eslik Eden Mycoplasma pneumonia Pnömonili Çocuk Olgu .

Hydatid cyst is a zoonotic disease and endemic in Turkey. The disease can involve any organ. The most common involved organ is lung in childhood. Hydatid cyst of lung may be asymptomatic or may be sometimes ruptured or infected. Secondary bacterial infections associated with the hydatid cyst are well known. A previously not reported pediatric case of hydatid cyst with Mycoplasma pneumoniae pneumonia is described in this report. It is emphasized that M. pneumoniae should be kept in mind as a cause of infected hydatid cyst which is unresponsive to beta-laktam antibiotics.
