Purpose: Necrotizing enterocolitis (NEC), a progressive inflammatory disorder, remains a significant clinical concern, and predictive factors for the disease continue to be investigated. This study aimed to evaluate the predictive role of complete blood count (CBC) parameters obtained within the first 24 hours postnatally, particularly platelet-related indices, in the development of NEC.Materials and Methods: This retrospective study included 49 preterm infants diagnosed with NEC and 50 preterm infants without NEC who were followed in the neonatal intensive care unit. CBC parameters obtained within the first 24 hours after birth, age at NEC diagnosis, modified Bell classification, and treatment modalities (conservative management, drain placement, or laparotomy) were analyzed.Results: A total of 99 preterm infants were included, of whom 52 were female and 47 were male. The mean birth weight was 1107.17 ± 458.94 g, and the mean gestational age was 27.8 ± 2.99 weeks. Platelet count (PLT) and plateletcrit (PCT) values measured within the first 24 hours postnatally demonstrated significant predictive value for NEC development. No statistically significant differences were identified between the NEC and control groups regarding other CBC parameters, including WBC, MPV, PDW, and RDW.Conclusion: PLT and PCT values obtained from CBC analyses within the first 24 hours postnatally, before the onset of clinical manifestations, may serve as valuable predictive markers for NEC development in preterm infants.

Background: Urinary tract infection (UTI) is a common cause of postoperative morbidity in children undergoing treatment for urolithiasis. This study evaluated the association of age‐appropriate ureteral stent length and intravesical stent position with urine culture (UC) positivity and symptomatic UTI. Methods: Children who underwent endourological treatment for nephrolithiasis or ureterolithiasis between September 2020 and September 2025 were retrospectively analyzed. Demographic characteristics, ureteral stent length, indwelling time, UC results, and symptomatic UTI were recorded. Stent length was categorized as short, appropriate, or long according to the (age + 10) formula. Intravesical position was classified as ipsilateral or cross‐trigonal based on whether the distal stent crossed the bladder midline. Results: Ninety‐nine children (57 boys, 42 girls; mean age, 8.8 ± 4.52 years) were included. The mean stent length was 17.69 ± 3.88 cm, and the mean indwelling time was 24.11 ± 5.79 days. Positive UC occurred in 21 patients, and 7 developed symptomatic UTIs. Both UC positivity and symptomatic UTIs were significantly associated with stents that were long for age, (both p < 0.001) and with a cross‐trigonal intravesical position ( p < 0.001 and p = 0.004, respectively). Conclusion: Age‐appropriate ureteral stent length and optimal intravesical positioning may reduce postoperative UC positivity and symptomatic UTIs in children undergoing surgical treatment for nephrolithiasis or ureterolithiasis. Careful attention to these modifiable factors may improve postoperative outcomes.

Background: The optimal treatment for pilonidal sinus disease remains controversial; however, minimally invasive methods are becoming increasingly common in children compared to traditional surgical approaches. This study aimed to compare the outcomes of two different minimally invasive methods for treating pediatric pilonidal sinus disease: phenol application and endoscopic pilonidal sinus treatment (EPSiT). Methods: Children who underwent EPSiT or phenolization for pilonidal sinus disease between January 2016 and January 2023 were included in the study. The patients' age, sex, treatment method, number of phenol applications or EPSiT procedures, visual analog scale (VAS) pain scores at postoperative 3 h, length of hospital stay, time to return to daily activities, early postoperative complications, and recurrence were analyzed. Results: A total of 61 patients were included in the study, 38 males (62.3%) and 23 females (37.7%). The mean age was 15.18 ± 1.7 years. Thirty patients (49.2%) were in the EPSiT treatment group, and 31 patients (50.8%) were in the phenol treatment group. Postoperative VAS pain scores were significantly higher in the phenolization group than in the EPSiT group (2.68 ± 1.92 vs. 1; p < 0.001). Time to return to daily activities, number of applications, early postoperative complications, and recurrence were significantly lower in the EPSiT group compared to the phenol group ( p < 0.001, p < 0.001, p = 0.023, and p < 0.001, respectively). Conclusion: For pediatric pilonidal sinus disease, EPSiT was more advantageous than phenol treatment in terms of postoperative pain, time to return to daily routine, early complications, and recurrence.

Amaç: Hirschsprung hastalığının yenidoğanlardaki preoperatif dönemde semptomatik olma süresinin tedavi sonuçları üzerine olan etkisinin araştırılmasıdır. Yöntem: Çalışmaya Ocak 2014-Ocak 2024 tarihleri arasında Mersin Üniversitesi Tıp Fakültesi Hastanesi Yenidoğan Yoğun Bakım ünitesinde Hirschsprung hastalığı nedeni ile tedavi edilen ve kolostomi açılan 15 hasta dahil edildi. Hastaların preoperatif klinik durumları, kolostomi açılma yaşları (= preoperatif dönem izlem süresi), kısa ve uzun segment Hirschsprung hastalığı olma durumları, postoperatif komplikasyonları kaydedildi. Hastaların kolostomi açılma yaşları, preoperatif klinik özelliklerine ve postoperatif komplikasyon durumlarına göre analiz edildi. Bulgular: Ortalama kolostomi açılma yaşı preoperatif dönemde intestinal pasaj sorunu (n=6), ileus (n=8) veya intestinal perforasyon (n=1) deneyimleyen hastalarda istatistiksel farklılık göstermedi (p=0.597). Postoperatif komplikasyon gelişen hastaların (n=6) ortalama kolostomi açılma yaşı, postoperatif komplikasyon gelişmeyen hastalara (n=9) göre daha büyük saptandı (88.8±8.3 güne karşılık 28.1±9.1 gün, p

Amaç: Bu araştırmada 6 Şubat 2023 tarihinde yaşanan deprem sonrasında Çocuk Cerrahisi Kliniği’nde tedavisi yapılan hastaların özelliklerinin belirlenmesi amaçlanmıştır. Yöntem: Retrospektif tanımlayıcı tipteki araştırma, 6 Şubat- 20 Şubat 2023 tarihleri arasında depremden etkilenip, Mersin Üniversitesi Hastanesi Çocuk Cerrahisi Kliniği’ne kabul edilen 43 hasta ile gerçekleştirilmiştir. Veriler anket formu ile toplanmıştır. Veriler SPSS paket program kullanılarak analiz edilmiştir. Bulgular: Yaş ortalaması 10.97±4.65 olup, %55.8’i kızdır. Göçük altında kalma süresi ortalama 16.44±19.12’dir. Hastaların tamamında ekstremite, batın ve toraks travması olup, %37.2’sinde ekstremitede yumuşak doku ezilmesi, %74.4’ünde batın duvarı cilt dermabrazyonu, %46.5’inde ise toraks duvarı cilt dermabrazyonu olmuş, %55.8’inde cerrahi işlem uygulanmış, %48.8’inde komplikasyon gelişmiş, %9.3’üne diyaliz, %18.6’sına eritrosit süspansiyonu uygulanmıştır. Ayrıca araştırmada göçük altında kalma süresi ile komplikasyon görülme durumu arasında anlamlı ilişki tespit edilmemiştir (p>.05). Sonuç: Deprem travmaları genel vücut travmaları içerisinde özellikli bir yere sahiptir. Deprem sonrası gelişen hafif travmalı olgularda dahi morbiditeye neden olabilecek sonuçlar ile karşılaşılabilmektedir. Bu nedenle, tanı ve tedavi süreçleri, deprem travmasına özgü olası komplikasyonlar dikkate alınarak planlanmalıdır.

Purpose: Phenol application is an increasingly popular method in the treatment of pediatric pilonidal sinus because of its ease of use. However, there has been insufficient research on standards for phenol application in children. This study aimed to determine standards for evaluating phenol applications to identify parameters that can be used in treatment planning. Methods: Pediatric patients with pilonidal sinus who underwent surgical excision and/or phenol injection between January 2011 and January 2021 were evaluated retrospectively. Data related to the patients’ age, sex, treatment method (phenol, surgery), number of phenol applications, preoperative complications and antibiotic use, postoperative complications, and treatment duration were analyzed. Results: The study included 57 patients, 34 boys (59.6%) and 23 girls (40.3%), with a mean age of 15.15±1.62 years (range: 11-18). Number of phenol applications and postoperative complications were significantly higher in patients with prolonged preoperative antibiotic use (>2 weeks) and preoperative complications (p<0.05). Length of hospital stay, wound dressing duration, and time to return to daily routine were significantly shorter in the phenol application group (p<0.001). Treatment duration and frequency of postoperative complications did not differ among the treatment groups (p˃0.05). Conclusion: This study suggest that phenol application is not superior to surgical treatment in terms of postoperative complications or treatment duration. The potential negative impact of prolonged preoperative antibiotic use and preoperative complications on the treatment process should be considered when deciding to use phenol for the treatment of pilonidal sinus.

The aim of this study is to contribute to the determination of the normal values of human anogenital distance (AGD) and anal position index (API) in the antenatal period. 59 formalin-fixed human fetuses were examined. AGD was measured by the distance between the center of the anus and the posterior fourchette in females, and the distance between the center of the anus and the posterior scrotal raphe in males. API in female fetuses was determined with the formula API = fourchette–center of anus/fourchette-coccyx formula, and API = posterior scrotal raphe-center of anus/posterior scrotal raphe-coccyx in males. The mean AGDs of the female and male fetuses in the second trimester were 5.60 ± 1.60 mm and 9.64 ± 2.75 mm and 12.88 ± 4.14 mm and 17.26 ± 5.55 mm in the third trimester, respectively. The AGD values were found to be significantly higher in the males (p = 0.002). While the API values detected in the female and male fetuses were 0.43 ± 0.085 and 0.55 ± 0.072 in the second trimester, they were 0.46 ± 0.079 and 0.55 ± 0.058 in the third trimester. The API values were found to be significantly higher in the male fetuses (p < 0.001). When the distribution of API values of the fetuses in the second and third trimesters was examined, no significant difference was found (p = 0.499). In addition, no significant correlation was found between API and AGD values and percentile groups of fetuses (p ˃ 0.05). The AGD and API differed significantly between female and male fetuses starting from the antenatal second trimester, and the difference was preserved independently of the fetal percentile in the later stages of pregnancy.

Nadir olarak görülen, vasküler erozyon ile gelişen, kateterin bulunduğu venin plevral veya perikardiyal alana açılması ile oluşan venobronşial fistüller, geç dönem port kateter komplikasyonları arasında yer almaktadır. Bu çalışmada, hemoptizi gibi sonuçlara yol açabilen, port kateter çekilmesi işlemini zorlaştıran, bu özellikleri ile hayati risk içeren bir komplikasyon olan venobronşial fistüllü bir olguyu sunmayı amaçladık.

Purpose To determine fetal clitoral dimensions in antenatal period and to provide a contribution to external genital morphology determination in premature infants. Methods Thirty-one formalin fixed female fetuses aged between 18 and 40 weeks (17 fetuses aged 21.53 ± 1.88 weeks in the second trimester and 14 fetuses aged 31.00 ± 4.90 weeks in the third trimester) were evaluated. 20 (64.5%) fetuses were between 3 and 97% percentile range and within normal limits. Clitoris appearance (completely covered by labium majus/partially showing/prominent), length and width of clitoris, labium minus length, length, and width of labium majus were assessed. Results Clitoris length during the second trimester was 4.84 ± 1.09 mm, whereas it was 5.43 ± 1.07 in the third trimester. Clitoris width was as 3.35 ± 0.88 mm in the second trimester and as 4.55 ± 0.96 mm in the third trimester. A statistically significant increase was seen in width of clitoris, length, and width of labium majus and length of labium minus with gestational age in the second and third trimesters (p < 0.05). No significant difference was found between the second and third trimesters in terms of clitoris length (p = 0.146). A homogenous spread in clitoris appearance was obtained between the second and third trimesters without any significant difference (p = 0.912). In addition, fetus percentiles showed a homogenous spread without any significant differences between completely covered, partially covered and prominent groups (p = 0.452). Conclusion The anatomical data can be beneficial to the development of fetal radiological screening procedures in females and also in morphological assessment criteria in premature infants, effectively assisting in diagnosing anomalies during the early term.
