Pediatricians' attitudes in management of acute otitis media and ear pain in Turkey.

Objectives: Acute otitis media (AOM) is predominantly a disease of childhood and one of the common reasons for prescribing antibiotics. Ear pain is the main symptom of AOM, with the result that parents frequently seek immediate medical assistance for their children. Antibiotic therapy for AOM does not provide symptomatic relief in the first 24 hours, and analgesics are commonly recommended for relieving the pain associated with AOM.

The prevalence, serogroup distribution and risk factors of meningococcal carriage in adolescents and young adults in Turkey.

The serogroup epidemiology of invasive meningococcal disease (IMD), which varies considerably by geographic region and immunization schedule, changes continuously. Meningococcal carriage data are crucial for assessing IMD epidemiology and designing f potential vaccination strategies. Meningococcal seroepidemiology in Turkey differs from that in other countries: serogroups W and B are the predominant strains for IMD during childhood, whereas no serogroup C cases were identified over the last 10 y and no adolescent peak for IMD was found.

Necrotizing Retinitis Secondary to Congenital Cytomegalovirus Infection Associated with Severe Combined Immunodeficiency.

A 20-day-old male infant who was born at 39 weeks of gestation was admitted to neonatal intensive care unit due to severe respiratory insufficiency. In retinal examination, peripheric retinal white-black color areas that correspond to necrotizing retinitis, moderate vitritis, macular and optic nerve head involvement, vascular leakage, and sheathing indicating perivasculitis were revealed. Despite the fact that CMV specific IgM was undetectable, CMV DNA with high viral load was found in his blood sample by means of real-time polymerase chain reaction assay.

Bacterial agents causing meningitis during 2013-2014 in Turkey: A multi-center hospital-based prospective surveillance study.

This is an observational epidemiological study to describe causes of bacterial meningitis among persons between 1 month and 18 y of age who are hospitalized with suspected bacterial meningitis in 7 Turkish regions. covering 32% of the entire population of Turkey. We present here the results from 2013 and 2014.

Serotype distribution of Streptococcus pneumoniae in children with invasive diseases in Turkey: 2008-2014.

Successful vaccination policies for protection from invasive pneumococcal diseases (IPD) dependent on determination of the exact serotype distribution in each country. We aimed to identify serotypes of pneumococcal strains causing IPD in children in Turkey and emphasize the change in the serotypes before and after vaccination with 7-valent pneumococcal conjugate vaccine (PCV-7) was included and PCV-13 was newly changed in Turkish National Immunization Program. Streptococcus pneumoniae strains were isolated at 22 different hospitals of Turkey, which provide healthcare services to approximately 65% of the Turkish population.

Determination of the presence of diphtheria toxin in the myocardial tissue of rabbits and a female subject by using an immunofluorescent antibody method.

Background: Clinical diagnosis of diphtheria is often difficult, in particular in countries where the disease is rarely observed, such as Turkey. In 2011, after 12 years of no recorded diphtheria cases in Turkey, a 34-year-old woman was diagnosed with diphtheria; she later died of myocarditis. In this study, we aimed to demonstrate the diagnostic potential of an immunofluorescent antibody method to determine the presence of diphtheria toxin (DT) in the myocardial cells of DT-injected rabbits and the female subject.

Candidaemia in a paediatric centre and importance of central venous catheter removal.

The aim of this study is to identify differences in distribution of Candida species, resistance to antifungals and clinical outcome, as well as the identification of potential risk factors associated with candidaemia in children. We conducted a retrospective analysis in children ≤18 years with blood culture proven candidaemia identified between 2004 and 2012. Patients were divided into two groups (Group 1, <3 months, n = 51; Group 2, ≥3 months, n = 197) to identify any potential difference between the neonatal and early infantile periods in terms of risk factors and distribution of Candida species.
