Aims and Objectives Trauma continues to be a major cause of morbidity and mortality world over. This study is aimed at the patterns of presentation and the outcome of management. Materials and Methods A prospective study of trauma patients admitted to Ahmadu Bello University Teaching Hospital through the Accident and Emergency units was commenced in January 2008.This preliminary report is for the period of 27months.The clinical history, physical examination and outcome of management recorded in a predesigned proforma, were analysed with SPSS 15 and the patients were followed up in the surgical outpatient department. Results A total of 4784 patients (3143 men and 1641 women) were admitted during this period for trauma. There were a total of 628(13.13%) deaths. Of the 42 consecutive patients identified with chest trauma35 (83.3%) were males and 7(16.7%) were females. The age range was from 5-75years and the mean age was 35.4years, while the most affected ages were in the range of 20 to 49years. Blunt injury constituted 71.4% and penetrating injury constituted 28.6%. Road traffic accident was responsible for 61.9%, stab injury 21.4%, falls 7.1%, gunshot injury 4.8%, impalement 2.4% and animal attack also 2.4%. The average time taken between accident and admission was 31hours,40minutes and 12seconds while the average duration of hospital stay was 16.10 days. The injury pattern included rib fracture(s) (23.8%), hemopneumothorax (14.3%), hemothorax (7.1%), pneumothorax (4.8%), combinations of chest injuries (7.1%), chest laceration 7.1%, bruises 11.9%, lung contusion 4.8%, subcutaneous empyema 2.4%, flail chest 4.8% and no specific injury (11.9%). Associated injuries included head injury (63.6%), orthopaedic injury (27.3%) and combinations (abdominal, head, orthopaedic (9.1%). The fatality of road traffic accident was 36.8%. No patient was attended to by paramedics at the scene of accident while 21.9% of the patients had prehospital resuscitation in peripheral clinics before admission. The transfusion requirement was 14.3%. One patient (2.4%) required a median sternotomy and cardiopulmonary bypass, 54.8% required tube thoracostomy while 42.9% had general resuscitation /non-operative intervention. Only one (2.4%) required ICU care. The complication rate was 4.8%. The mortality rate was 2.4%. Only 7(16.7%) patients were seen beyond the first outpatient clinic appointment. Conclusion Most patients arriving at the hospital survived, requiring general resuscitation or simple tube thoracostomy with few complications. Mortalities from trauma and the cause of death at the site of accident are often not accounted for due to nonpresentation to the hospital and lack of autopsy for those that present.
Primary chest wall tumors are uncommon and constitute 0.2-2% of all tumors. Metastatic tumors and tumors of local extension are more common. Malignant peripheral nerve sheath tumor (MPNST) of the chest wall is even rarer and its incidence on the chest wall not stated in the literature. The incidence in the general population is 0.0001% while the risk is approximately 4600 times higher in patients with type I neurofibromatosis and 3-13% of them will finally develop into MPNST, usually after latent periods of 10-20 years. Clinically, these tumors are aggressive, locally invasive, and highly metastatic. Excision of giant chest wall tumor leaves a defect that is reconstructed using musculocutaneous flaps with or without a mesh. We report the case of a 24-year-old man who presented at the surgical outpatient clinic with 7 months history of persistent left sided chest pain minimally relieved by analgesics, 5 months of cough and worsening dyspnoea, and 3 months history of anterior chest swelling on the left side of the manubrium. Following evaluation and investigations, the tumor was excised and the residual defect closed with methylmetacrylate sandwiched between two prolene meshes and overlaid with both pectoralis major muscles. The histology of the excised mass revealed MPNST He made an uneventful postoperative recovery, but died barely 3 months later from widespread pulmonary metastases. A review of the literature revealed that such tumors hardly ever reach such large-size as in our case.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
