Amaç: Pseudomonas aeruginosa (P. aeruginosa), özellikle duyarlı hastalarda ciddi infeksiyonlara yol açabilen fırsatçı bir mikroorganizmadır. Yoğun bakım ünitelerinde (YBÜ) invazif aletlerin kullanılmasıyla ortaya çıkan hastane kaynaklı infeksiyonlar ve salgınlar hasta yaşamı açısından önemli bir tehdite yol açmaktadır. Bu çalışmada, pediatri YBÜ’de kullanılan laringoskopların kontaminasyonundan kaynaklandığı tespit edilen bir P. aeruginosa salgını sunulmuştur.Gereç ve Yöntemler: 21 Mayıs- 17 Ağustos 2012 tarihleri arasında pediatri YBÜ’de yatan altı hastanın çoklu antibiyotik dirençli P. aeruginosa (ÇADPa) ile infekte olduğu belirlendi. Olguların zaman ve yer açısından kümelenmesi nedeniyle hastane salgını olabileceği düşünüldü. Bu salgının kaynağını bulmak için çevresel örnekler toplandı. Mikrobiyoloji laboratuvarımızda uygun inkübasyon sonrası ileri identifikasyonlar ve antibiyotik duyarlılık testleri yapıldı.Bulgular: İdentifikasyon ve antibiyotik duyarlılık testleri sonucunda bu YBÜ’de kullanılan iki laringoskoptan ÇADPa izole edildi. Bu suşlar ile hastalardan izole edilen suşların antibiyotik duyarlılık paternleri benzerlik gösterdi. ÇADPa üreyen altı hastaya bu laringoskoplarla tekrarlanan entübasyonlar yapıldığı ve salgının reentübasyonlarda kullanılan laringoskoplardan kaynaklandığı tespit edildi.Sonuç: Hastane ortamında kullanılan çeşitli aletlerin kontaminasyonu sonrasında nozokomiyal ÇADPa salgınları olabileceği düşünülmelidir. Salgın varlığında hedefe yönelik sürveyans yapılmalı ve infeksiyon kontrol önlemleri daha sıkı uygulanmalıdır.

Objective: Pseudomonas aeruginosa (P. aeruginosa), is an opportunistic microorganism that causes serious infections especially in susceptible patients. Nosocomial infections and outbreaks seen after the use of invasive instruments in intensive care units (ICU) seriously threaten patient survival. We report a Pseudomonas aeruginosa outbreak that was found to be caused by contamination of laryngoscopes used in the pediatric ICU.Material and Methods: Six patients in the pediatric ICU were diagnosed multi drug resistant P. aeruginosa (MDRPa). A nosocomial outbreak was suspected as the cases were aggregated with regard to time and place. Environmental specimens were collected to explain the source of this outbreak. Antibiotic susceptibility tests and advanced identifi cation tests following incubation were performed. Results: After identifi cation and antibiotic susceptibility tests, MDRPa was detected from two laryngoscopes used in the pediatric ICU. The antibiotic susceptibility patterns of these strains and those isolated from the patients were similar. Recurrent intubations had been performed in those six MDRPa-isolated patients and the outbreak was found to have originated from these laryngoscopes.Conclusion: Contamination of various instruments used in hospitals can cause nasocomial MDRPa outbreaks. When detected, surveillance should target the cause and strict prevention strategies to control infection should be utilized

The publication language of Turkish Journal of Pediatric Disease is English.
Manuscripts submitted to the Turkish Journal of Pediatric Disease will go through a double-blind peer-review process. Each submission will be reviewed by at least two external, independent peer reviewers who are experts in the field, in order to ensure an unbiased evaluation process. The editorial board will invite an external and independent editor to manage the evaluation processes of manuscripts submitted by editors or by the editorial board members of the journal. The Editor in Chief is the final authority in the decision-making process for all submissions. Articles accepted for publication in the Turkish Journal of Pediatrics are put in the order of publication, with at least 6 original articles in each issue, taking into account the acceptance dates. If the articles sent to the reviewers for evaluation are assessed as a senior for publication by the reviewers, the section editor and the editor considering all aspects (originality, high scientific quality and citation potential), it receives publication priority in addition to the articles assigned for the next issue.
The aim of the Turkish Journal of Pediatrics is to publish high-quality original research articles that will contribute to the international literature in the field of general pediatric health and diseases and its sub-branches. It also publishes editorial opinions, letters to the editor, reviews, case reports, book reviews, comments on previously published articles, meeting and conference proceedings, announcements, and biography. In addition to the field of child health and diseases, the journal also includes articles prepared in fields such as surgery, dentistry, public health, nutrition and dietetics, social services, human genetics, basic sciences, psychology, psychiatry, educational sciences, sociology and nursing, provided that they are related to this field. can be published.
