[A rare complication of blunt trauma; diaphragm-pericardium rupture and cardiac herniation in a child case]. / Künt travmanin nadir komplikasyonu; Çocuk olguda diyafram-perikart rüptürü ve kardiyak herniasyon.

Diaphragma and pericardium rupture is rarely seen after blunt trauma. It's treatment is surgery. A 4-year-old male patient who was operated for diaphragm and pericardium rupture which developed after blunt trauma; rarity of this union, differences in the clinical and radiological features in children was examined.

Effects of a 12-week structured circuit exercise program on physical fitness levels of children with autism spectrum condition and typically developing children.

Purpose: This study aimed to determine the effects of a circuit exercise program on the physical fitness parameters of children with atypical autism spectrum condition (ASC) and typically developing (TD) children. Method: Fourteen (14) boys with atypical autism (mean age: 10.07 ± 0.25 years; weight: 24.97 ± 0.64 kg; height: 126.79 ± 1.33 cm) and 14 typically developing boys (mean age: 10.07 ± 0.30 years; weight: 26.97 ± 0.55 kg; height: 126.50 ± 0.62 cm) participated in the study. The children were divided into four groups using a random coin toss: Autism Exercise Group (AEG), Autism Control Group (ACG), Typically Developing Exercise Group (TDEG), and Typically Developing Control Group (TDCG). Testing parameters from the Bruininks-Oseretsky test of gross motor proficiency (BOT-2) included running speed and agility, balance, bilateral coordination, and the standing long jump. Handgrip strength (both sides), reaction times (visual and auditory), and flexibility tests were also performed. The exercise program consisted of three 60-minute sessions per week for 12 weeks, using the most-to-least prompting method. Findings: Significant improvements were observed for AEG in running speed and agility, balance, standing long jump, reaction times, handgrip strength, and flexibility (p < 0.05). For TDEG, only the standing long jump scores failed to significantly improve (p < .05). Comparing AEG and TDEG pre- and post-test results, the former showed 30% greater development with respect to balance, standing long jump, auditory reaction time, and handgrip strength (p < 0.05). Conclusion: Based on the significant improvements in physical fitness parameters of AEG, we recommend that children with ASC start sports training immediately when diagnosed with autism and participate in structured physical activities with their peers.

[Treatment for esophageal perforations: analysis of 11 cases]. / Özofagus perforasyonlarinda tedavi: On bir olgunun analizi.

BACKGROUND: We present 11 cases with esophageal perforations who were treated in our department, with the intent of underlining the importance of surgical intervention. METHODS: We retrospectively analyzed 11 cases of esophageal perforation who were treated from 2005 to 2010. The cases diagnosed within the first 24 hours were regarded as early diagnoses; those diagnosed later than this period were regarded as late diagnoses. RESULTS: The mean age of the patients was 45.8 years. Following the perforation, 3 of the patients had early diagnoses and the others had late diagnoses. Of the 3 cases with early diagnosis, all had primary repair; of the late diagnosis cases, 4 had primary repair, 2 had colonic interposition, 1 had stent implantation, and 1 received medical treatment. All the cases with late diagnoses underwent drainage. The 3 cases who received early treatment recovered without complications. Of the other 8 cases, 1 had leakage from the anastomosis and 1 developed a fistula. Two (18.1%) of our patients died. CONCLUSION: Treatments performed before the development of mediastinitis are lifesaving in esophageal perforation patients. We think that surgical treatment performed within the first 72 hours that includes primary repair would yield favorable results.

The effect of TiO2 coating on biological NiTi alloys after micro-arc oxidation treatment for corrosion resistance.

NiTi alloys exhibit good properties, such as shape memory behavior, high corrosion resistant, having the closest elasticity modulus of a human bone and superior biocompatibility properties. However, the surface problems that arise during the use of this alloy limit the usage in the industry and health sector. In recent years, micro-arc oxidation method is used to improve the surface properties and increase the usage of these alloys. In this study, the TiO2 coatings were deposited on the NiTi substrates. The surface topography, morphology, crystallographic structure, and thickness of the coatings were determined using scanning electron microscopy and X-ray diffraction. The corrosion properties were investigated using potentiostat test unit in two different media such as NaCl solution and simulated body fluid. The results show that the coated samples have higher corrosion resistance than uncoated samples in the two different media.
