Introduction: An operational computed tomography (CT) scanner is a major source of human exposure to ionizing radiation. Exposure increases the risk of cancer and aplastic anaemia. All radiation exposures should be justified and optimized to meet the clinical objective. In order to avoid the administration of excessive radiation dose to patients, diagnostic reference l...

Introduction: The present study was conducted to obtain State diagnostic reference levels (DRLs) of five routine computed tomography (CT) examinations from two CT centers in Ondo State and to identify factors responsible for dose variation and escalation in these CT centers. Material and Methods: Acquisition parameters and CT dose indices wer...

A 58-year-old man presented with retrosternal pain 30 months after a surgical operation for reflux esophagitis in relation to Barrett’s esophagus. Gastroscopy revealed an ulcer of the inferior part of the esophagus, which on biopsy proved to be an adenocarcinoma. Additional surgery was performed through the abdomen and through the thorax via the sixth intercostal space. Resection of the lower p...

A 14-year-old boy was admitted to our hospital due to persisting pleuritic pain in the right lower hemithorax, which presented after athletic activities. Chest X-ray showed a right hemothorax for which a chest tube was inserted. The patient’s medical history was positive for exostoses of both humeri and the left femur, for which he had undergone an operation at the age of 5 and 8 years, respect...

background : medical x-rays are the largest man-made source of public exposure to ionizing radiation. while the benefits of computed tomography (ct) are well known in accurate diagnosis, those benefits are not risk-free. ct is a device with higher patient dose in comparison with other conventional radiation procedures. objective: this study is aimed at evaluating radiation dose to patients from...

STUDY OBJECTIVES Previous articles have promoted the early use of thoracotomy and decortication for refractory empyema. This study examines thoracoscopy and decortication at the time of initial chest tube placement in pediatric patients with parapneumonic empyema. DESIGN We reviewed the medical records of 16 consecutive patients who were children with parapneumonic empyema. RESULTS Thirteen...

Chest tube insertion is the most commonly performed procedure in the thoracic surgery practice. This surgical procedure has various complications, however, Horner’s syndrome resulting from compression of the stellat ganglia due to apical insertion of chest tube is extremely rare. In this article a 21-year-old male patient who was treated with chest tube insertion for spontaneous pneumothorax at...

Introduction: Recently, the use of nanoparticles has increased for many purpose in medicine. One of these is using the nano particles in shields structure to protect sensitive organs such as breast which placed inside the field of chest CT scan and receives high dose. The aim of this study was the use of nano Bi2O3 to making shield for protection breast in chest CT examination ...

Abstract Introduction Neurological deficit associated with firearm injury outside the head and neck region is a rare phenomenon. Multiple explanations, including pellet embolization, patent foramen ovale carotid intimal tear, have been suggested. Case Report We present case of an otherwise healthy 21-year-old male, who was received in emergency injury, unstable vitals, GCS 14/15. Bullet entry w...
