Giriş: Purpura fulminans nadir görülen bir klinik tablodur. Yenidoğan döneminde sıklıkla konjenital veya kazanılmış protein C veya S eksikliğinden kaynaklanır. Sepsis ilişkili yaygın damar içi pıhtılaşma da bir diğer risk faktörüdür.Yöntem: Üçüncü basamak bir yenidoğan yoğun bakım ünitesinde Ocak 2008 ile Mayıs 2010 tarihleri arasında purpura fulminans tanısı ile izlenmiş olguların dosyaları geriye dönük olarak incelendi. Olguların faktör 5 Leiden, protrombin G20210A ve metilentetrahidrofolat redüktaz mutasyonu sonuçları, plazma protein C, S, antitrombin 3, antifosfolipid antikor ve homosistein düzeyleri ve kültür sonuçları kaydedildi.Bulgular: Toplam yedi olgunun verileri değerlendirildi. Olguların tamamının tanı anında plazma protein C, S ve antitrombin 3 düzeyi düşüktü. Metilentetrahidrofolat redüktazın homozigot mutasyonu bir olguda, heterozigot mutasyonu ise bir diğer olguda saptandı. Homosistein düzeyi metilentetrahidrofolat redüktaz mutasyonu olan olgularda hafif yüksek; diğerlerinde ise normaldi. Bir olguda tedavi sonrasında protein C, S ve antitrombin 3 düzeyi tekrarlanabildi ve sonuçlar normal bulundu. Dört olgunun kan kültüründe etken, izole edildi. İzole edilen mikroorganizmalar Pantoea agglomerans, Candida albicans, Klebsiella pneumonia ve Staphylococcus hominis’di.Sonuç: Bildiğimiz kadarıyla serimiz bugüne kadar yayınlanmış en geniş purpura fulminans tanılı yenidoğan olgu serisidir ve Pantoea agglomerans, Candida albicans ve Klebsiella pneumonia yenidoğanlarda purpura fulminans etkenleri olarak ilk kez bu seri ile gösterilmiştir. Purpura fulminans tanısı ile izlenen ve etiyolojide sepsis ilişkili yaygın damar içi pıhtılaşma düşünülen yenidoğan olgularda bu nadir patojenler de akılda tutularak tedavi ve takipler planlanmalıdır.
Introduction: Purpura fulminans is a rare clinical entity. In the neonatal period it is commonly caused by inherited or acquired protein C or S deficiency. Disseminated intravascular coagulation associated with septicemia in newborns may be another risk factor for purpura fulminans. Methods: Charts of the patients followed up with the diagnosis of purpura fulminans at a tertiary level neonatal intensive care unit between January 2008 and May 2010 were retrospectively reviewed. Factor 5 Leiden, prothrombin 20210 A and methylenetetrahydrofolate reductase mutations, levels of plasma protein C, S, antithrombin III, antiphospholipid antibody and homocystein, and culture results were recorded in all the patients. Results: Results of a total of seven patients were evaluated. Plasma protein C, S and antithrombin III levels were found decreased at the time of diagnosis in all the cases. One of the cases had methylenetetrahydrofolate reductase homozygous mutation, and another had methylenetetrahydrofolate reductase heterozygous mutation. Homocystein levels were slightly elevated in cases with methylenetetrahydrofolate reductase mutation, and normal in the others cases. Plasma protein C, S and antithrombin 3 levels were studied in only one case after treatment and were normal. A pathogen was identified in blood culture in four out of the seven cases. The isolated microorganisms were Pantoea agglomerans, Candida albicans, Klebsiella pneumonia and Staphylococcus hominis.Conclusion: Pantoea agglomerans, Candida albicans, and Klebsiella pneumonia were determined as the causative agents of purpura fulminans in this series of newborns, which, to our knowledge, is the largest one reported till now. These pathogens should be remembered in infants who are followed up with the diagnosis of purpura fulminans and suspected to have disseminated intravascular coagulation associated with sepsis

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 10 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.
