Purpose The aim of the study was to investigate whether the skeletal age can be evaluated assessed by means of analysis of ossification stage at proximal humeral epiphysis using magnetic resonance imaging (MRI). Methods This retrospective study was carried out in the radiology department of a tertiary healthcare center and 1.5-T MRI views of the shoulder obtained from 203 patients aged 8 to 29 years were evaluated. The ossification stage of proximal humeral epiphysis was evaluated on T1-weighted MRI sequences, and its correlation with age was sought. Results Our series consisted of 77 women (37.9%) and 126 men (62.1%). One hundred forty-seven right humerus (72.4%) and 56 (27.6%) left humerus were examined. The mean age of the patients was 20.60 ± 4.41 years. The patients were in stages 4 (n = 148, 72.9%), 3c (n = 18, 8.9%), 3b (n = 14, 6.9%), 2c (n = 13, 6.4%), and 3a (n = 10, 4.9%). Analysis of the relationship between age and ossification stage of proximal humerus epiphysis indicated that stage increased with the advancement of age. There was a significant correlation between the stage and age variables at a rate of 77% in the positive direction (P < 0.001). Conclusions Our results demonstrated that MRI of proximal humeral epiphysis can have valuable implications for estimation of the skeletal age. Future prospective studies must be implemented with patients grouped according to socioeconomic status, nutritional habits, and physical activities to explore the actual investigative potential of MRI.

Objective: To investigate whether three-dimensional (3-D) reformatted cranial computed tomography (CT) scans may contribute to the avoidance of misdiagnosis of skull fractures in pediatric emergency cases. Materials and Methods:This cross-sectional medical chart review was carried out in the pediatric emergency department of a tertiary care center. Data were derived from pediatric age group patients having head trauma patients whose conventional CT images were obtained at initial admission. Demographic, clinical, and radiological data, the location of the fracture, and possible causes of misdiagnoses were recorded. Results:This study included 27 children (21 males and six females). The average age was 41.92±43.25 (range, 1 to 137) months. The most common etiology for admission to the hospital was fall from height (85.2%). The fractures were detected on the parietal (n=12, 44.4%), frontal (n=7, 25.9%), occipital (n=7, 25.9%) and temporal (n=1, 3.7%) bones. In 12 cases (44.4%), skull fracture could not be detected at their initial admission. Five of these 12 cases were consulted to the radiologist, and diagnosis could not be established even by the radiologist. In 15 pediatric head trauma patients (55.6%), the skull fracture was confirmed by the radiologist. In two cases with an initial failure of diagnosis, 3-D reconstruction allowed the identification of fractures. Conclusion:The findings obtained in this study suggest that 3-D reconstruction of CT scans may increase the accuracy of diagnosis for pediatric skull fractures.

Amaç: Refrakter anemi tanısı ile takip edilen olgularda paroksismal nokturnal hemoglobinüri (PNH) sıklığını ortaya koymak. Hastalar ve Yöntem: Hematoloji polikliniğimize başvuran refrakter anemisi olan hastalar çalışmaya dahil edildi. Rutin tam kan sayımı ve biyokimyasal testler sistemik çoklu-autoanalyzer kullanılarak yapıldı. Serum demir, toplam demir bağlama kapasitesi ve serum ferritin düzeyleri değerlendirildi. Tüm hastalarda kemik iliği aspirasyonu ve kemik iliği biyopsisi yapıldı. PNH klonu, nötrofillerin CD59 ifadelerindeki kusura göre değerlendirildi. Bulgular: Toplam 18 refrakter anemi hastası çalışma için uygunluk kriterlerini karşıladı. Grafikleri gözden geçirilen 18 hastanın (9 erkek, 9 kadın) yaş ortalaması 76.4 idi. PNH klonu, çalışmaya dahil edilen herhangi bir hastada saptanmadı. Sonuç: Refrakter anemili hastalarda hemoliz için klinik kanıt olmasa da PNH klonu için rutin tarama öneren çalışmalar literatürde mevcuttur. Ancak biz bu çalışmada, refrakter anemili hasta grubumuzda PNH klonuna rastlamadık. Bu konu ile ilgili daha fazla sayıda hasta içeren çalışmalara ihtiyaç vardır.
