Background Fosfomycin is gaining increasing attention for its activity against MDR or XDR pathogens. Currently, IV fosfomycin is a potential option for treating various infections, including urinary tract infections, pneumonia and skin infections when first-line treatments fail. Objectives To evaluate the demographic, clinical, microbiological and treatment modality of children received IV fosfomycin to treat infections caused by MDR pathogens since there are few data on the use of fosfomycin in children. Methods This study was conducted retrospectively with patients under 18 years of age who were treated with IV fosfomycin for at least 72 h due to infections caused by MDR pathogens between January 2019 and October 2023 at Marmara University Pendik Training and Research Hospital, İstanbul, Türkiye. Data on demographic and clinical features, microbiological findings, treatment modalities and side effects were evaluated. Results Twenty-five children, for a total of 32 cases of infection episodes, with a mean age of 11.4 ± 3.92 years who received IV fosfomycin were included. The most frequent comorbidity was chronic pulmonary diseases, and the most common infection needed for IV fosfomycin was MDR Pseudomonas aeruginosa pneumonia. In all cases, fosfomycin was administered in combination with other antibiotics, mainly meropenem–colistin (68.7%) or meropenem (15.6%). Twenty-two (71.9%) cases had favourable clinical responses at the end of therapy. Conclusions Our results suggest that IV fosfomycin may be an effective treatment option for MDR pathogens in the paediatric population. Nevertheless, careful stewardship is necessary to maintain efficacy and reduce antimicrobial resistance selection risk. [ABSTRACT FROM AUTHOR]

- Abstract
Objective: To investigate the importance of immunization in preventing measles infection and to determine the most useful laboratory tests for confirmation of measles. Methods: This study included pediatric cases evaluated with a presumed diagnosis of measles between December 2022 and June 2023, at Marmara University Pendik Training and Research Hospital. The effects of vaccination status and underlying disease on the clinical course, treatments, and complications were evaluated. Results: In total, 117 patients were enrolled in the study with a median age of 80 months (IQR: 32.5-125.0). Twelve patients with contact history were asymptomatic and had an underlying disorder, and intravenous immunoglobulin was given to them for postexposure prophylaxis. Fifty-one patients had confirmed measles diagnosis. Ribavirin treatment was given to three patients (a newborn, a girl with rhabdomyosarcoma, and a healthy boy) with respiratory distress. Seventy-eight percent of confirmed measles cases were unvaccinated, and all hospitalized cases were unvaccinated or undervaccinated. Four full-vaccinated children had confirmed measles infection. Measles PCR from nasopharyngeal swabs was negative in all of them, and their diagnosis was established with anti-measles IgM positivity. Conclusions: The measles vaccine is the most effective way to protect from measles and measles-related complications. Although measles can also occur in fully vaccinated patients, the disease is milder than in unvaccinated patients. Using ELISA and RT-PCR tests together may be beneficial in patients with high clinical suspicion for early diagnosis. [ABSTRACT FROM AUTHOR]

Echinococcosis is the most common cestode infection globally caused by the Echinococcus species. The most common organ involvement is the lungs and liver, but other organs can be rarely involved. Here, we present a case with a giant cerebral hydatid cyst. A 4-year-old boy presented with abnormal gait and walking at Marmara University School of Medicine Pendik Training and Research Hospital, Istanbul, Türkiye in September 2022. Cranial magnetic resonance imaging showed a cyst of 13 cm in diameter. The cyst was enucleated successfully with no rupture. Oral albendazole therapy was started. There was no eosinophilia, and the echinococcal indirect hemagglutination test was negative. Ultrasonography detected an anechoic cystic lesion in the liver. He was evaluated for deeporgan involvement; however, no cysts were detected in other organs. The histopathological examination was compatible with a hydatid cyst. Although intracranial hydatid disease in children is rare, it should be considered among the differential diagnoses in patients with neurological symptoms, especially in endemic regions.

Bu araştırma, sekizinci sınıf düzeyindeki öğrencilerin matematik alanındaki öğrenme eksiliklerinin, zayıf ve güçlü oldukları konuların belirlenmesi amacı ile yapılmıştır. Bu bağlamda, öğrencilerin yanıtlama tepkileri üzerinde madde türlerinin bir etkisinin olup olmadığı da incelenmiştir.Bu amaç doğrultusunda, Bilişsel Tanı Modellerinden DINA model ile analiz çalışmaları yürütülmüştür. Analiz sürecinde, TIMSS 2015 sekizinci sınıf matematik değerlendirmesi kapsamında uygulanan iki kitapçık ve 69 maddeden elde edilen öğrenci verileri ve maddelerin konu alanlarıyla ilişkisini gösteren Q matris kullanılmıştır. Konu alanlarını temsil eden bilişsel özellikler üç alan uzmanı tarafından sekizinci sınıf matematik öğretim programı ve TIMSS 2015 değerlendirme çerçevesi incelenerek belirlenmiştir. Bu çalışma sonrasında, her bir madde, uzmanlar tarafından belirlenen 14 özellik ile ilişkilendirilerek Q matrisler oluşturulmuştur.Maddelerden elde edilen bulgular, g (tahmin) ve s (kaydırma) parametrelerinin düşük, δ (ayırt edicilik) parametresinin yüksek olduğunu göstermektedir. Maddelere ait parametre değerleri incelendiğinde, g parametresine ait ortalamaların sırasıyla 0.24 ve 0.19, s parametresine ait ortalamaların 0.21 ve 0.20 olduğu görülmektedir. Testlere ait δ ortalama değerlerinin, 0.55 ve 0.60 olduğu belirlenmiştir. Özelliklerin gözlenme sıklıklarına ilişkin sonuçlar incelendiğinde, testleri yanıtlayan öğrenci grubunun yaklaşık yarısının belirlenen özelliklere sahip olmadığı belirlenmiştir. Öğrenme alanları kapsamında bakıldığında, öğrencilerin en az sahip oldukları özelliklerin başında sayılar öğrenme alanında yer alan `kesirler ve ondalık gösterimler` ve cebir öğrenme alanında yer alan `cebirsel ifade ve işlemler` özelliği gelmektedir. Geometri öğrenme alanında öğrencilerin en zayıf olduğu özelliğin `dönüşüm geometrisi` olduğu belirlenmiştir.Madde türüne ilişkin analiz sonuçları incelendiğinde, açık uçlu maddelerden elde edilen s parametrelerinin daha yüksek çıktığı görülmektedir. Bu sonucun özellikle kısmi puanlanan maddelerde biraz daha arttığı gözlenmiştir. Çoktan seçmeli maddelerde ise, g parametresinin daha yüksek olduğu belirlenmiştir. Aynı özelliği ölçen çoktan seçmeli ve açık uçlu maddelerle ilgili bulgular incelendiğinde, çoktan seçmeli bir maddede özelliğe sahip öğrencilerin yanlış yanıtlama olasılıkları çok düşük iken, aynı bilişsel özellikleri ölçen açık uçlu maddede özelliğe sahip öğrencilerin yanlış yanıtlama olasılıkları yüksek çıkmıştır. This research was conducted with the aim of determining the learning deficits and areas that are weak and strong in the mathematics of the eighth grade students. In this context, it has also been examined whether there is an effect of item types on students' response.For this purpose, analysis studies were carried out with the DINA model from the Cognitive Diagnostic Models (CDM). In the analysis process, two booklets were applied TIMSS 2015 eighth grade mathematics evaluation and student data obtained from 69 items and Q matrix showing the relation with learning areas of the items were used. Cognitive attributes representing learning areas were determined by three field experts by examining the eighth grade mathematics curriculum and TIMSS 2015 assessment frameworks. After this study, Q matrices were created by associating each item with 14 properties determined by experts.Findings from the data indicated that the g (guess) and s (slip) parameters were low and the δ (item discriminant) parameter was high. When the parameters values of the items were examined, it had seen that the averages of g parameter were 0.24 and 0.19, the averages of s parameter were 0.21 and 0.20. Mean values of δ for the tests were determined to be 0.55 and 0.60.When the conclusions regarding the frequency of observations of attributes were examined, it was determined that about half of the students who responded to the tests did not have the specified attributes. When it comes to learning areas, it comes from the `fractions and decimal representations`, which are at the top of the attribute that students had at least in the learning field, and the `algebraic expressions and operations` attribute in the area of learning algebra. It has been determined that the weakest attribute of the students in geometry learning is the `rotation geometry`.When the analysis results of the item type were examined, it was seen that the s parameters obtained from the open ended items were higher. It was observed that this result was slightly increased especially in the partial scoring items In the case of multiple choice items, the parameter g is determined to be higher. When the findings of multiple choice and open ended items that measure the same attribute were examined, students with an attribute in a multiple choice item had a very low probability of false answers, whereas students with the same attribute in the open ended item had a high probability of false answers. 139

Bu çalışmanın amacı; Türkiye’de eğitim araştırmalarında kayıp veri sorunun ne düzeyde dikkate alındığının ve kayıp veri sorununa yönelik olarak hangi yöntemlerin daha yaygın bir şekilde kullanıldığının belirlenmesidir. Nitel bir araştırma olarak tasarlanan bu araştırmada, belgesel tarama yöntemi kullanılmıştır. Türkiye’de, araştırma kapsamında belirlenen ölçütleri karşılayan dört eğitim dergisinde, 2009-2011 yılları arasında yayımlanan toplam 708 makale, üç araştırmacı tarafından eş zamanlı olarak incelenmiştir. Ulaşılan bulgular, özellikle kayıp veri sürecinin raporlanmasında ciddi eksiklikler bulunduğunu göstermektedir. İncelenen araştırmaların 405’i, istatistiksel analiz süreçleri içermekle birlikte bu araştırmaların ancak 31’inde kayıp veri sorunu bulunduğu açıkça belirlenebilmiştir. Söz konusu 31 araştırmadan sadece 7 tanesinde kayıp veri yöntemi kullanıldığı, fakat bu kullanımın çok da bilinçli olarak yapılmadığı görülmüştür. Anlaşılan odur ki; Türkiye’de eğitim araştırmalarında kayıp veri sorununa nerdeyse tamamen ilgisiz kalınmaktadır

Thepurpose of this study, 8th grade school students to investigate therelationship between course achievement scores and test scores. To this end, inthe 8th grade SBS sub-test raw scores and course achievement scores wereexamined by multivariate canonical correlation analysis. In this study, thefirst set of variables is sub-test scores, the second variables is courseachievement scores. Before analysis, the data were examined compliance with theassumptions of canonical correlation analysis method and adversely affect thecorrelation between variables not included in the analysis outliers. Accordingto the results of a canonical correlation was significant only between two setsof variables. This case provides evidence for the fact that scores concerningsome of the courses were not sufficiently consistent with SBS sub-test scoresas expected., Buaraştırmanın amacı, 8.sınıf öğrencilerinin okul başarı puanları ile testpuanları arasındaki ilişkiyi araştırmaktır. Bu amaçla, 8.sınıflar için yapılanSeviye Belirleme Sınavının (SBS) alt test ham puanları ile aynı derslere aityıl sonu okul başarı puanları arasındaki ilişki çok değişkenli kanonik korelasyonanalizi ile incelenmiştir. Bu çalışmada birinci değişken setinde alt test hampuanları, ikinci değişken setinde okul başarı puanları yer almaktadır. Analizöncesinde, verilerin kanonik korelasyon analiz yönteminin varsayımlarınauygunluğu incelenmiş ve değişkenler arası korelasyonu olumsuz yöndeetkileyebilecek aykırı değerler analize katılmamıştır. Elde edilen sonuçlaragöre iki değişken seti arasında sadece bir kanonik korelasyon önemlibulunmuştur. Bu nedenle bazı derslere ait okul başarı puanlarının, SBS alt testpuanlarını beklendiği gibi yeterince açıklayamadığı sonucuna ulaşılmıştır.

Bu çalışmada, mesleki bilgi gerektiren bir derste yapılan uygulamanın, puanlama anahtarı ve dereceli puanlama anahtarı kullanılarak değerlendirilmesi sonunda elde edilen puanlar karşılaştırılarak, iki farklı ölçme yöntemiyle verilen puanların uyum düzeylerinin araştırılması amaçlanmıştır.Araştırma bir meslek lisesinin elektrik-elektronik bölümündeki 70 öğrenciden oluşan 6 grup ve 6 öğretmenin katılımı ile yapılmıştır. Öğrencilere verilen performans görevi her grupta 2 öğretmen tarafından değerlendirilmiştir. Bir öğretmen puanlama anahtarı ile diğer öğretmen dereceli puanlama anahtarı ile puanlama yapmıştır.İki farklı ölçme yöntemiyle verilen puanlar karşılaştırılırken, bu puanların uyum düzeyi ve bu puanlarla okul notlarını uyum düzeyi araştırılmıştır. Elde edilen bulgulara göre, her bir grupta elde edilen puanlar arasında yüksek bir uyum olduğu görülmüştür. Puanlama anahtarı ve dereceli puanlama anahtarı ile verilen puanların ortalamaları arasındaki ilişkiyi belirlemek için t testi yapılmış ve dereceli puanlama anahtarı ile verilen puanların ortalamalarının daha yüksek olduğu görülmüştür. Bu dersin 1. döneme ait notlarıyla, her iki puanlama yöntemi ile verilen puanlar arasındaki korelasyona bakılmış ve dereceli puanlama anahtarı ile verilen puanların korelasyonunun daha yüksek çıktığı görülmüştür. Ancak, iki korelasyon katsayısı farkı 0.05 düzeyinde manidar çıkmamıştır. Regresyon analizi sonucunda, dereceli puanlama anahtarı ile verilen puanların okul notlarını yordama düzeyi daha yüksek çıkmıştır. Son olarak, dereceli puanlama anahtarıyla ilgili öğretmen görüşlerinin alındığı bir anket uygulanmış ve dereceli puanlama anahtarı ile puanlamanın daha objektif ve öğrenci başarısı üzerinde daha etkili olduğu, ancak böyle bir ölçme aracının hazırlanmasının zor ve puanlamanın çok zaman aldığı yönünde sonuçlara ulaşılmıştır. By this study, evaluation of an examination related to an applied lesson requiring vocational knowledge, has been made by using answer key and scoring rubric and it was aimed to compare the compatibility of the scores given by these two different grading methots.The investigations were made by the attendance of 6 teachers and 70 students in 6 groups from the electrical-electronics department of a vocational high school. The performance task given to the students were evaluated by 2 teachers at each group. One of teachers employed the answer key and the other used the scoring rubric for the tests.During the comparison process of these two different grading methods, concurrency of the scores given by each grading methods and compliance of these scores with grades of school. In evaluation of the obtained findings, it was observed that there was a high level of consistency at each group. With a view to determining the relation between the averages of the scores given by the answer key and scoring rubric t-test have been performed and it was observed that the averages of the scores given by scoring rubric were higher than the scores given by answer key. The correlation between the grades of this lesson belonging to the first term and the scores given by both grading methods were observed and as a result it was noted that correlation of the scores given by scoring rubric were a higher than the scores given by answer key. But, the difference between two correlation coefficient as 0.05 was not meaningful. As the result of the regression analysis, the regression level of the scores given by scoring rubric of grades of school were higher than the answer key. Finally, a survey were performed on the opinions of the involved teachers on the rubric and it was concluded that; scoring by employing rubric were more objective and more effective on the success of the students; but the preparations of such a method was difficult which needed plenty of time. 77

SEZGİSEL BELİRTİSİZ TOPOLOJİK UZAYLARDA BELİRTİSİZ BAĞLANTILILIKLAR Burcu Parlak ÖZ Üç bölümden oluşan bu çalışmada amacımız sırasıyla, belirtisiz topolojik uzay larda, sezgisel belirtisiz topolojik uzaylarda ve sezgisel topolojik uzaylarda bağlantılılık türlerini incelemektir. 1. bölümde, belirtisiz topolojik uzaylarda Q (i=l,2,3,4,S,M) bağlantılı, Q9-bağlantılı, O-bağlantılı, C5 ve süper C5-bağlantılı kümelerin tanımları verildi ve bu bağlantılılık türleri arasındaki ilişkiler, örnekler de verilerek incelendi. Daha sonra, C5-bağlantılılığın, zayıf süreklilik, hemen hemen süreklilik ve a-süreklilik türleri altında korunduğu ispat landı. 2. bölümde, sezgisel belirtisiz topolojik uzaylarda, Ci-bağlantılılık (1=1,2,3,4), C5 ve Cm-bağlantılılık, süper bağlantılılık, C5-bağlantılılık, bağlantılılık ve kuvvetli bağlantılılık tanımları verildi ve birbirleri ile ilişkileri incelendi. Ayrıca, C5 ve Cm-bağlantılılığın sezgisel belirtisiz topolojik uzaylarda birbirine özdeş ifadeler olduğu kanıtlandı. Son bölümde, sezgisel belirtisiz topolojik uzaylarda olduğu gibi sezgisel topolojik uzaylarda da bağlantılılık türlerinin tanımları verildi ve aralarındaki ilişkiler incelendi. Sezgisel topolojik uzaylarda teoremlerin kanıtları, sezgisel belirtisiz uzaylardaki ile ben zerlik gösterdiğinden tekrar verilmedi. Anahtar Kelimeler: Belirtisiz küme, belirtisiz topolojik uzaylar, belirtisiz bağlatılılık, sezgisel belirtisiz küme, sezgisel belirtisiz topolojik uzaylar, sezgisel belirtisiz bağlantılılık, sezgisel küme, sezgisel topolojik uzaylar, sezgisel bağlantılılık. Danışman: Prof.Dr. Haydar EŞ, Hacettepe Üniversitesi, Matematik Bölümü FUZZY CONNECTEDNESS IN INTUITIONISTIC FUZZY TOPOLOGICAL SPACES Burcu Parlak ABSTRACT The aim of this theses, which consist of three chapters, is to examine connectedness types in fuzzy topological spaces, intuitionistic fuzzy topological spaces and intuition- istic topological spaces, respectively. In the first chapter, the definitions of Q (i= 1,2,3,4,S,M) connected, Qç-connected O-connected, C5 and super Cs-connected sets are given and relationships between each other are examined with examples. Apart from these definitions above, then it is proved that Cs-connectedness is preserved under weak continuity, almost continuity and a-continuity. In the second chapter, the definitions of Q-connectedness (i= 1, 2, 3, 4), Cs and CM-connectedness, super connectedness, Cs-connectedness, connectedness and strong connectedness are given in the intuitionistic fuzzy topological spaces and then their relationships with each other are examined. Afterwards, it is proved that Cs and CM-connectedness types are identical in intuitionistic fuzzy topological spaces. In the final chapter, definitions of connectedness types in intuitionistic topological spaces are given and their relationships with each other are examined in intuitionis tic fuzzy topological spaces. The proofs of theorems are not given in intuitionistic topological spaces since they are similar to the proofs given in the intuitionistic fuzzy topological spaces. Keywords : Fuzzy sets, fuzzy topological spaces, fuzzy connectedness, intuitionis tic fuzzy sets, intuitionistic fuzzy topological spaces, intuitionistic fuzzy connectedness, intuitionistic sets, intuitionistic topological spaces, intuitionistic connectedness.

Bu araştırmada, İzmit'te bulunan DUŞA (Endüstriyel İplik Üretimi) ve SEKA (Kağıt ve Selüloz Üretimi) fabrikalarının atık su arıtma tesislerinde atık suyun arıtılması sonrasında ortaya çıkan antma çamurlarının İzmit Alikahya Köyün'den alınan tarım toprağının fiziksel, kimyasal ve biyolojik özellikleri üzerinde yapmış olduğu etkiler araştırılmıştır. Bu amaçla, laboratuvarda hazırlanan toprak-çamur karışımları su tutma kapasitelerinin %70'i kadar nemlendirilerek ve bu nemin %0.5'den fazla kaybolmamasına özen gösterilerek +28°C'de 5 aylık bir süre boyunca bırakılmıştır. Belli oranlarda atık çamur örnekleri uygulanmış (kontrol, 20, 40, 80, 160 ton/ha) toprak örneklerinde 10 ayrı inkübasyon dönemi dikkate alınarak azot mineralizasyonu (NH4-N ve N03-N), toprak solunumu (C02 çıkışı) ve üreaz enzim aktiviteleri belirlenmiştir. İnkübasyon döneminin başında belirlenen toprak ve çamurların fiziksel ve kimyasal özelliklerinde, inkübasyon sonrasında değişiklik olup olmadığını, meydana gelen değişikliklerin hangi çamurda ve hangi dozda meydana geldiğini, değişikliğin olumlu yada olumsuz olduğunu, meydana gelen olumlu değişimlerde en uygun çamur uygulama dozunu bulmak amacıyla inkübasyonun son dönemindeki örneklerde, başta yapılan fiziksel ve kimyasal analizler tekrarlanarak sonuçlar istatistiki olarak karşılaştırılmıştır. Araştırmadan elde edilen bulgulara göre toprağın organik madde, %saturasyon, EC25°C, yarayışlı fosfor, kireç miktarı, nem içeriği, solma noktası, tarla kapasitesi, serbest iyonları, KDK'sı, değişebilir katyonlarının miktarında her iki çamurda da dozlara bağlı olarak artma, pH değerinde azalma görülürken diğer fiziksel ve kimyasal özelliklerde önemli bir değişiklik saptanamamıştır. SEKA çamuru, solma noktası, nem içeriği, toplam azot, %saturasyon, tarla kapasitesi, serbest iyonlar üzerindeki değişimlerde DUŞA çamurundan daha etkili iken, DUŞA çamuru, pH düşmesinde, hacim ağırlığının, organik maddenin, EC25°c'nin, yarayışlı fosforun, kireç miktarının, toplam fosforun artmasında Seka çamuruna oranla daha etkili olmuştur. İnkübasyon denemesi sonunda her iki çamurda hızlı mineralizasyon gözlenmiş olup doza bağlı olarak başlangıçtaki NH4-N miktarı artmış, inkübasyon süresine bağlı olarak da nitrifikasyon olayı önemli ölçüde etkilenmiştir (p

- Abstract
The purpose of this study, 8th grade school students to investigate the relationship between course achievement scores and test scores. To this end, in the 8th grade SBS sub-test raw scores and course achievement scores were examined by multivariate canonical correlation analysis. In this study, the first set of variables is sub-test scores, the second variables is course achievement scores. Before analysis, the data were examined compliance with the assumptions of canonical correlation analysis method and adversely affect the correlation between variables not included in the analysis outliers. According to the results of a canonical correlation was significant only between two sets of variables. This case provides evidence for the fact that scores concerning some of the courses were not sufficiently consistent with SBS sub-test scores as expected. [ABSTRACT FROM AUTHOR]

- Abstract
Background: Fosfomycin is gaining increasing attention for its activity against MDR or XDR pathogens. Currently, IV fosfomycin is a potential option for treating various infections, including urinary tract infections, pneumonia and skin infections when first-line treatments fail., Objectives: To evaluate the demographic, clinical, microbiological and treatment modality of children received IV fosfomycin to treat infections caused by MDR pathogens since there are few data on the use of fosfomycin in children., Methods: This study was conducted retrospectively with patients under 18 years of age who were treated with IV fosfomycin for at least 72 h due to infections caused by MDR pathogens between January 2019 and October 2023 at Marmara University Pendik Training and Research Hospital, İstanbul, Türkiye. Data on demographic and clinical features, microbiological findings, treatment modalities and side effects were evaluated., Results: Twenty-five children, for a total of 32 cases of infection episodes, with a mean age of 11.4 ± 3.92 years who received IV fosfomycin were included. The most frequent comorbidity was chronic pulmonary diseases, and the most common infection needed for IV fosfomycin was MDR Pseudomonas aeruginosa pneumonia. In all cases, fosfomycin was administered in combination with other antibiotics, mainly meropenem-colistin (68.7%) or meropenem (15.6%). Twenty-two (71.9%) cases had favourable clinical responses at the end of therapy., Conclusions: Our results suggest that IV fosfomycin may be an effective treatment option for MDR pathogens in the paediatric population. Nevertheless, careful stewardship is necessary to maintain efficacy and reduce antimicrobial resistance selection risk., (© The Author(s) 2024.

- Abstract
Neurobrucellosis is rare in children, presenting with a variety of clinical manifestations, including meningitis, meningoencephalitis, cranial neuropathies, and intracranial mass-like lesions. We present a case of a 17-year-old girl admitted to the hospital in Istanbul for headache. Lumbar puncture showed elevated intracranial pressure, monocytic pleocytosis, elevated total protein, and hypoglycorrhachia. Brucella melitensis grew from the cerebrospinal fluid. The patient was treated with doxycycline, rifampin, amikacin, and ceftriaxone and showed persistent sensorineural hearing loss. It is essential to consider brucellosis in the differential diagnosis of infectious neurological disease in areas where the disease is endemic. Serologic tests and cultures are needed for diagnosis, and efforts need to be made to identify the infecting organism to the species level to guide zoonotic source control efforts.

- Abstract
Background: The Kahramanmaras earthquakes in Turkey on February 6, 2023, resulted in more than 100 000 injuries and 50 500 deaths. The main causes of morbidity and mortality in earthquake-affected patients include crush syndrome, trauma-related extremity injuries, and wound infections., Objective: To investigate infective complications, causative microorganisms, treatments, and treatment responses in pediatric patients., Methods: The case series involved 12 earthquake victims admitted to a tertiary treatment center between February 9 and 24, 2023. Wound sample cultures were obtained from patients with infected wounds via wound secretions and tissue samples collected during surgery., Results: Nine patients were male (75%), and the mean age of patients was 12.6 ± 3.7 years. Seven patients (58.3%) experienced crush syndrome. Seven patients (58.3%) underwent fasciotomy operations. The main infectious complications were wound infections (58.3%) and urinary tract infections (25%). Nine different organisms were found to cause wound infection, with Enterococcus faecium (41.6%), Acinetobacter baumanii (33.3%), and Pseudomonas aeruginosa (16.6%) being the major bacterial isolates. All Acinetobacter strains were multidrug-resistant (MDR)., Conclusion: Major disasters such as earthquakes are rare, and infections are the major complications that increase morbidity and mortality. Initial appropriate treatment contributes to improved outcomes, as MDR strains are common pathogens in these patients.

- Abstract
Background: Purpura fulminans (PF) is a rare, life-threatening condition involving consumptive coagulopathy and intravascular thrombosis, causing purpura and necrosis in the skin and soft tissue., Case Report: A 4-year-old Tajik girl with PF secondary to varicella-zoster virus (VZV) infection presented with purplish red, diffuse, painful lesions localized to the entire right leg. Her vaccination status was unknown, and she did not have concurrent chronic illness. Ten days before admission, the girl was admitted to another hospital in Tajikistan with a diagnosis of chickenpox and PF. She was then transferred to the hospital of the authors of the current report due to the enlargement of lesions to the gluteal region, a change in the color of lesions from red to black, and the detection of arterial thrombosis via Doppler ultrasonography. Multiple surgical debridements were performed to manage tissue necrosis, and the patient's right leg was amputated at the 18th week of admission. The patient was discharged after 26 weeks of hospitalization., Conclusion: Although VZV infections mostly cause mild and self-limiting eruptive disease, they can progress, with life-threatening complications, including PF. To prevent VZV infection and resulting complications, immunization with live attenuated vaccines and maintaining population immunity above a certain threshold are the most important strategies to prevent the circulation of the virus.
