    Abstract Background: Trauma is a leading cause of childhood injuries. Although blunt traumas in children are more common in penetrating traumas, children in civilian life and near conflict areas can often be affected by gunshot wounds. Among all gunshot wounds, thoracic injuries constitute a significant proportion. In our study, we detected bullet trajectory in children with gunshot wounds penetrating the thorax by analyzing reformatted images of multidetector computed tomography (CT).
    Methods: Nineteen pediatric patients with thoracic gunshot wounds were evaluated retrospectively. After all patients admitted the emergency service, their hemodynamics were stabilized first. Then, PA-AC radiography and thorax CT were taken and necessary imaging studies of other body parts were performed. CT scans were performed with multi-detector CT.
    Results: Using reformatted axial, sagittal, and coronal and oblique images of multidetector CT, we detected projectile trajectory in the lung parenchyma in 74% of patients. In 26% of the patients, the projectile trajectory could not be detected due to excessive parenchymal hemorrhage, hemothorax, and pneumothorax.
    Conclusion: In our study, a standard could not be made due to the fact that the types of weapons used could not be determined, the firing distances could not be known, different ages and different bullet entry and exit angles. However, detecting the trajectory of the bullet in the lungs will assist the physician in making the treatment plan and following up the patient. In addition, the evaluation of the data obtained will be beneficial to forensic medicine physicians and scientists interested in wound ballistics.

    Abstract Introduction: Although pelvic inflammatory disease is seen in sexually active women, it can also be seen in virgin girls. One of the conditions that can develop if not treated appropriately is pyosalpinx. A case of pyosalpinx causing xanthogranulomatous inflammation, a rare type of inflammation, is presented.
    Case: A 15-year-old virgin adolescent patient underwent salpingectomy for left pyosalpinx, and the pathology result revealed xanthogranulomatous salpingitis.
    Conclusion: Pelvic inflammatory disease is extremely rare in virgin adolescents and there is usually an underlying anatomic anomaly. No anatomical anomaly was detected in our case, but the detection of E.coli in the abscess fluid culture and the chronic constipation of our patient made us think that the cause of the disease was an ascending infection originating from the gastrointestinal tract.

    Abstract Background: Esophageal perforations are rare, the most common encountered esophageal perforation is iatrogenic in origin. It can be life-threatening if not diagnosed and treated early. Medical treatment has been recommended primarily in hemodynamically stable children. Drainage of intrathoracic or periesophageal fluid formation should be reserved to patients with hemodynamic instability. Surgical intervention may seldomly be required, depending on the localization and size of the defect.
    Case report: A 6-year-old male patient was referred to our clinic due to an esophageal perforation whilst removing the foreign body from upper esophagus under direct vision of a rigid esophagoscope. A radiologic appearance similar to esophageal duplication was detected along the esophagus in the esophagogram. A secondary esophagoscopy was carried out by our clinic, laceration at the esophagopharyngeal junction and dissection along the esophagus were observed and the foreign body was propelled into the stomach. The patient, whose clinical condition was stable, was managed medically without the need for a surgical intervention.
    Conclusions: Esophageal perforation is rare, yet perilous if not handled properly. We do not encounter this clinical entity frequently. Despite its rarity it can arise either iatrogenically or while managing a previous complication such as a simple nasogastric tube insertion in an infant or during an endoscopy for an esophageal foreign body. Its management is challenging, and we believe that non-operative treatment is still an important option in childhood esophageal perforations.

    Abstract Genitourinary system injuries generally occur due to blunt and penetrating trauma. Approximately 10% of all injuries encountered in the emergency department are related to the genitourinary system. Male genital trauma is a urological emergency because of the high risk of infection and the priority of protecting the sexual, endocrine, and reproductive functions. Blunt injuries to the penis are more often seen due to the mobility and localization of the penis than due to penetrating injuries caused by firearms or cutting instruments. We aimed to present and discuss a case involving shrapnel that became lodged in the penis of a child in a war zone. After 2 weeks of medical treatment, the patient underwent surgery. Surgery includes primary repair to the penis and urethra.

    Title translation Ostol'ün sıçanlarda testis iskemi/reperfüzyon hasarı üzerine koruyucu etkisi.
    Abstract Background: Testicular torsion is a urological emergency that requires urgent surgical intervention which results in testicular loss if not diagnosed and treated in a timely fashion. Ischemic tissue damage with oxygen deficiency, which starts with the decrease in blood flow to the tissue, continues to increase with the reoxygenation of the damaged tissues as soon as reperfusion is achieved. In various studies, osthole has also been shown to reduce cerebral, spinal cord, intestinal, renal, and myocardial ischemia/perfusion (I/R) damage. The aim of this study is to examine the effects of osthole on testicular I/R injury.
    Methods: 28 Wistar-albino rats were randomly divided into four experimental groups (n=7). Group 1 was the sham operation group. In Group 2 (I/R), 3-h ischemia was created by rotating the testis 720° clockwise, followed by 3 h of reperfusion. In Group 3 (I/R + single dose of Osthole), 20 mg/kg ostol was administered intraperitoneally half an hour before detorsion after 3 h of torsion. The testis was detorsioned. Three h of detorsion was applied. In Group 4 (I/R + twice doses of Osthole), 20 mg/kg ostol was administered intraperitoneally half an hour before detorsion, followed by 3-h torsion. The testis was released and detorsioned. Half an hour after the detorsion, an intraperitoneal dose of 20 mg/kg osthole was administered again. Detorsion was done for 3 h. All rats were sacrificed after 6 h and right orchiectomy was performed for blood for biochemical analysis and histopathological sample.
    Results: Glutathion, nuclear respiratory factor 2, Superoxide dismutase, and 8-hydroxydeoxyguanosine levels were decreased in I/R rats, while interleukin-6, malondialdehyde, and myeloperoxidase levels were increased. While caspase 3, caspase 8, caspase 9, and TUNEL showed moderate immunopositive tissues immunohistochemically in rats with I/R damage, mild immunopositive tissues were detected in Group 3 and Group 4. In the histochemical examination, degenerative tubule structure and separation of epithelial cells were observed in I/R rats, while partially healed testicular tissue was detected in Group 3 and Group 4.
    Conclusion: In our study, we observed that osthole reduced oxidative damage, suppressed the inflammatory process, prevented apoptosis, and reduced cell damage. We think that with repeated doses, cellular damage would gradually decline.

    Abstract The vast majority of teratomas originating from more than a single germ layer are benign. Often, such teratomas are initially asymptomatic. Later symptoms are caused by the weight per se of the teratoma and include chest pain, cough, dyspnea, and/or recurrent attacks of pneumonia. A mediastinal teratoma is treated by total surgical resection of the mass. Here, we report a case of giant mature cystic teratoma mimicking a pleural effusion in the thorax at the 7-month-old female patient with a symptom of persistent pulmonary infection and tachypnea.
