Thoracic Injuries (thoracic + injury)
Selected AbstractsBLUNT CHEST TRAUMA IN CHILDHOODANZ JOURNAL OF SURGERY, Issue 8 2007Mustafa Inan Background: Although thoracic injuries are uncommon in children, their rate of morbidity and mortality is high. The aim of this study was to evaluate the clinical features of children with blunt chest injury and to investigate the predictive accuracy of their paediatric trauma scores (PTS). Methods: Between September 1996 and September 2006, children with blunt thoracic trauma were evaluated retrospectively. Clinical features and PTS of the patients were recorded. Results: There were 27 male and 17 female patients. The mean age was 7.1 ± 3.4 years, and the mean PTS was 7.6 ± 2.4. Nineteen cases were injuries caused by motor vehicle/pedestrian accidents, 11 motor vehicle accidents, 8 falls and 6 motor vehicle/bicycle or motorbike accidents. The following were noted: 28 pulmonary contusions, 12 pneumothoraxes, 10 haemothoraxes, 9 rib fractures, 7 haemopneumothoraxes, 5 clavicle fractures and 2 flail chests, 1 diaphragmatic rupture and 1 pneumatocele case. The cut-off value of PTS to discriminate mortality was found to be ,4, at which point sensitivity was 75.0% and specificity was 92.5%. Twenty-seven patients were treated non-operatively, 17 were treated with a tube thoracostomy and two were treated with a thoracotomy. Four patients who suffered head and abdominal injuries died (9.09%). Conclusion: Thoracic injuries in children expose a high mortality rate as a consequence of head or abdominal injuries. PTS may be helpful to identify mortality in children with blunt chest trauma. Blunt thoracic injuries in children can be treated with a non-operative approach and a tube thoracostomy. [source] Delayed Presentation of Injury to the Sinus of Valsalva with Aortic Regurgitation Resulting from Penetrating Cardiac WoundsJOURNAL OF CARDIAC SURGERY, Issue 3 2003Narutoshi Hibino M.D. An emergency operation was performed successfully to repair the penetrating cardiac injury of the right ventricular outflow tract without using cardiopulmonary bypass. Two years after the operation, he was complained of dyspnea and a continuous murmur was detected. Echocardiography and cardiac catheterization revealed aorto-right ventricular fistula in the sinus of valsalva with aortic regurgitation. In operation, the healed laceration of the right coronary cusp and the fistula between aorta and right ventricle were identified. The fistula was closed using a Dacron patch and the aortic valve was replaced with a mechanical valve. Long-term follow-up of penetrating thoracic injuries is important for detecting underlying intracardiac lesions. (J Card Surg 2003;18:236-239) [source] Broken ribs: Paleopathological analysis of costal fractures in the human identified skeletal collection from the Museu Bocage, Lisbon, Portugal (late 19th to middle 20th centuries)AMERICAN JOURNAL OF PHYSICAL ANTHROPOLOGY, Issue 1 2009Vítor Matos Abstract Although rarely reported in the anthropological literature, rib fractures are commonly found during the analysis of human skeletal remains of past and modern populations. This lack of published data precludes comparison between studies and restricts an accurate understanding either of the mechanisms involved in thoracic injuries or their impact on past societies. The present study aimed: 1) to report rib fracture prevalence in 197 individuals, 109 males, and 88 females, with ages at death ranging from 13 to 88 years old, from the Human Identified Skeletal Collection, Museu Bocage, Portugal (late 19th-middle 20th centuries); 2) to test the hypothesis that a higher prevalence of rib stress fractures existed in the 133 individuals who died from respiratory diseases, in a period before antibiotics. The macroscopic analysis revealed 23.9% (n = 47) of individuals with broken ribs. 2.6% (n = 124) out of 4,726 ribs observed were affected. Males presented more rib fractures, and a significantly higher prevalence was noted for older individuals. Fractures were more frequently unilateral (n = 34), left sided (n = 19) and mainly located on the shaft of ribs from the middle thoracic wall. Nineteen individuals presented adjacent fractured ribs. Individuals who died from pulmonary diseases were not preferentially affected. However, a higher mean rate of fractures was found in those who died from pneumonia, a scenario still common nowadays. Since rib involvement in chest wall injury and its related outcomes are important issues both for paleopathology and forensic anthropology, further investigations are warranted.

[source] Brain-derived neurotrophic factor applied to the motor cortex promotes sprouting of corticospinal fibers but not regeneration into a peripheral nerve transplantJOURNAL OF NEUROSCIENCE RESEARCH, Issue 2 2002G.W. Hiebert Abstract Previous experiments from our laboratory have shown that application of brain-derived neurotrophic factor (BDNF) to the red nucleus or the motor cortex stimulates an increase in the expression of regeneration-associated genes in rubrospinal and corticospinal neurons. Furthermore, we have previously shown that BDNF application stimulates regeneration of rubrospinal axons into a peripheral graft after a thoracic injury. The current study investigates whether application of BDNF to the motor cortex will facilitate regeneration of corticospinal neurons into a peripheral nerve graft placed into the thoracic spinal cord. In adult Sprague Dawley rats, the dorsal columns and the corticospinal tract between T9 and T10 were ablated by suction, and a 5-mm-long segment of predegenerated tibial nerve was autograft implanted into the lesion. With an osmotic pump, BDNF was infused directly into the parenchyma of the motor cortex for 14 days. Growth of the corticospinal tract into the nerve graft was then evaluated by transport of an anterograde tracer. Anterogradely labeled corticospinal fibers were not observed in the peripheral nerve graft in animals treated with saline or BDNF. Serotinergic and noradrenergic fibers, as well as peripheral sensory afferents, were observed to penetrate the graft, indicating the viability of the peripheral nerve graft as a permissive growth substrate for these specific fiber types. Although treatment of the corticospinal fibers with BDNF failed to produce regeneration into the graft, there was a distinct increase in the number of axonal sprouts rostral to the injury site. This indicates that treatment of corticospinal neurons with neurotrophins, e.g., BDNF, can be used to enhance sprouting of corticospinal axons within the spinal cord. Whether such sprouting leads to functional recovery after spinal cord injury is currently under investigation. © 2002 Wiley-Liss, Inc. [source] The need for nurses to have in service education to provide the best care for clients with chest drainsJOURNAL OF NURSING MANAGEMENT, Issue 2 2007Cert., DANIELA LEHWALDT BNS The need for nurses to have in service education to provide the best care for clients with chest drains Chest drains are a widespread intervention for patients admitted to acute respiratory or cardiothoracic surgery care areas. These are either inserted intraoperatively or as part of the conservative management of a respiratory illness or thoracic injury. Anecdotally there appears to be a lack of consensus among nurses on the major principles of chest drain management. Many decisions tend to be based on personal factors rather than sound clinical evidence. This inconsistency of treatment regimes, together with the lack of evidence-based nursing care, creates a general uncertainty regarding the care of patients with chest drains. This study aimed to identify the nurses' levels of knowledge with regard to chest drain management and identify and to ascertain how nurses keep informed about the developments related to the care of patients with chest drains. The data were collected using survey method. The results of the study revealed deficits in knowledge in a selected group of nurses and a paucity of resources. Nurse managers are encouraged to identify educational needs in this area, improve resources and the delivery of in service and web-based education and to encourage nurses to reflect upon their own knowledge deficits through portfolio use and ongoing professional development.
