Perfil epidemiológico do trauma de face dos pacientes atendidos no pronto socorro de um hospital público

OBJETIVO: Avaliar os dados epidemiológicos e a localização dos traumas de face de pacientes atendidos no Hospital Regional da Asa Norte (HRAN), Brasília, Distrito Federal. MÉTODO: Trata-se de um estudo retrospectivo, realizado no pronto socorro do HRAN-DF, visando avaliar o perfil epidemiológico dos pacientes atendidos pela equipe da Unidade de Cirurgia Plástica vítimas de trauma de face no período de 1 de janeiro a 31 dezembro de 2004. RESULTADOS: O estudo compreendeu 711 pacientes, destacando-se o sexo masculino (72,8%). Quanto à causa, predominou a agressão física, seguida por acidente com veículos/motos. As quedas foram a causa predominante das lesões em crianças, mas verificou-se a participação cada vez maior da agressão física como mecanismo de trauma facial com o aumento da idade. A relação de homem:mulher foi de 3:1. A faixa etária mais atingida foi de 21 a 30 anos, representando 35,3% dos pacientes. As fraturas foram encontradas em 24,9% das lesões faciais. O nariz foi o local mais acometido nas fraturas de face (76,8%). CONCLUSÃO: A violência interpessoal foi a principal causa de trauma de face. A queda da própria altura mostrou-se como importante mecanismo de trauma nos extremos de idade.

Pancreatico-enterostomy for isolated main pancreatic duct disruption

We present our experiences with isolated main pancreatic duct injuries due to blunt trauma, managed by pancreatico-enterostomies. This is a retrospective study of seven patients, one female and six males who presented between 1997 and 2005, whose ages ranged from 10 to 54 years. Three were due to motor vehicle accidents, two due to blunt assault, one pedestrian vehicle accident and one go-cart accident. Four presented acutely and were managed surgically within 24h; two were delayed by 3 days and one by 14 days. Six had pre-operative CT scans; one had an ERCP confirming ductal transection by contrast extravasation. Five pancreatico-gastrostomies and two pancreatico-jejenostomies were performed. Three patients complicated; one by biliary cutaneous fistula after a left hepatic segmentectomy, one with an amylase-rich low output fistula and one with haematemesis, for which no cause could be identified. All complications were managed conservatively. Post-operative follow-up ranged between 4 and 20 weeks. No deaths occurred. In a stable patient, pancreatico-enterostomy for an isolated main pancreatic duct injury appears to be a viable option and simpler to perform than distal pancreatectomy with splenic preservation. Furthermore, it has the advantage of pancreatic tissue and spleen preservation and a low fistula rate. The authors believe pancreatico-gastrostomy to be the easier to perform.

Cervical Spine Injury is Highly Dependent on the Mechanism of Injury Following Blunt and Penetrating Assault

The mechanism of injury has not been highly regarded as an important variable when evaluating cervical spine injuries. The aim of this study was to determine the incidence of cervical spine fracture (CSF) and cervical spinal cord injury (CSCI) based on mechanism following blunt and penetrating assault to better aid prioritization of management. Retrospective analysis from two large urban Level I trauma centers over 87 and 144 months caused by gunshot wounds (GSW), stab wounds (SW) or blunt assault (BA). During the study period, there were 57,532 trauma patients evaluated at the two trauma centers, of which 42.3% were following blunt or penetrating assault. The rates of CSF and CSCI for the various mechanisms were similar between the two centers. The rates for having CSF were significantly different (p < 0.05) for the various mechanisms. GSW (1.35%) was the highest followed by BA (0.41%) and then SW (0.12%). The rates of CSCI for GSW (0.94%) were significantly (p < 0.05) higher than BA (0.14%) and SW (0.11%). For GSW patients, all patients with CSF or CSCI had a point of entry between the ears and the nipple. For SW patients, the wound was directly in the neck below the mandible and above the trapezius muscle. Although many of the SW patients also suffered blunt assault, none of the CSF or CSCI injuries were from blunt forces. In addition, all patients, both blunt and penetrating who had CSCI had neurologic deficit at the time of presentation. Surgical stabilization or tongs were applied in 15.5% (26 of 168) of the GSWs, 27.8% (3 of 11) of the SWs and 31.6% (6 of 19) of the BA patients. There was a BA patient (1 of 4,390) patient with CSF that was neurologically intact that required surgical stabilization and this patient had neck pain on admission. No penetrating injury patients with CSCI regained significant neurologic recovery during the hospitalization. The rate of CSF or CSCI is low following assault and dependent on mechanism of injury. Thus the concern and extent of evaluation should also be dependent on the mechanism of injury. Neurologic deficits from penetrating assault were established and final at the time of presentation. Concern for protecting the neck should not hinder the evaluation process or life saving procedures.

Clearing the Cervical Spine in Victims of Blunt Assault to the Head and Neck: What is Necessary?

A number of guidelines have been proposed to aid in determining the need for radiologic evaluation of the cervical spine (c-spine) in victims of blunt trauma. Mechanism of injury has not been shown to be an independent predictor of injury or the lack thereof. The current study was undertaken to determine the incidence of clinically relevant c-spine injuries in patients who sustained a blunt assault to the head and neck. The trauma registry of an urban Level 1 trauma center was used to identify patients who suffered a blunt assault to the head and neck and were admitted to the hospital over a 30-month period. One hundred two patients were identified. Only 8 patients met criteria for clinical clearance of the c-spine. Eighty patients were unable to be evaluated because of head injury or intoxicants; 14 patients had neck pain on initial examination. These 94 patients underwent plain film examination of their c-spine. Twelve required CT scanning to supplement visualization. The possibility of ligamentous injury was investigated by MRI or flexion/extension radiographs in 26 patients. No clinically significant c-spine injuries were identified. Although many victims of a blunt assault to the head and neck region may have a decreased LOC or neck pain, the likelihood of a ligamentous injury is so low that plain-film X-ray evaluation of the c-spine is all that is necessary to rule out injury in this patient population.

Epidemiology of facial injury in female blunt assault trauma cases.

Etiology of trauma in the female population differs from that of the male population. To date, domestic violence has been researched extensively, but little has been published about the epidemiology of facial injury in the female population. To analyze the differences in the circumstances under which males and females are injured, to identify gender-specific patterns of injury, and to assess whether differences in the demographics, health status, and drug-use profile exist between female and male assault cases and whether these factors lead to a difference in outcome. A cohort of 91 female assault cases was compared with a control group of 706 males with similar injuries resulting from blunt assault trauma. Information was gathered by retrospective review of 797 consecutive cases requiring admission for facial injuries resulting from blunt assault trauma. Fisher exact, chi 2, and t tests were used to assess statistically significant differences between the male and female cohorts. The female cohort comprised 12% of all cases admitted for blunt assault facial trauma. One third of female blunt assault facial trauma patients were subjects of domestic violence. Statistically significant differences were found between males and females for the type of assault (rape, domestic violence, altercation, etc) with P < .0001. Females were more likely to be admitted with soft tissue injury only but no fracture (P < .05), less likely to be assaulted with a weapon, and unlikely to be involved in an altercation, gang violence, arrest, or robbery. Females were also less likely than males to be injured while intoxicated (P < .05). Incidence of specific injury patterns and outcomes, however, were similar between the 2 groups. The present data support the hypothesis that the female blunt assault facial trauma population represents a distinct epidemiological entity, with significant differences in the circumstances of injury, mechanism of assault, and role of intoxication in the incidence of injury. The prevalence of facial trauma in female assault cases makes it critical for the facial plastic surgeon to be vigilant in the evaluation and treatment of these patients.

Epidemiology of facial injury in blunt assault. Determinants of incidence and outcome in 802 patients.

Facial assault trauma has reached epidemic proportions. While the biomechanics of injury, methods of repair, and general demography of blunt facial trauma are well known, statistical associations between epidemiological factors, incidence, and outcome are poorly understood. To provide a comprehensive epidemiological survey of this patient population. To assess factors determining outcome and pattern of injury. Retrospective review of 802 patients admitted with blunt assault facial trauma. Statistical analysis of associations between epidemiological factors, incidence, and outcome with chi 2 test, 2-tailed t test, and Fisher exact test. Urban university and county hospital. Statistically significant associations are demonstrated between gender and the context of assault, incidence of armed assault, presence of fracture, and rate of intoxication at injury. Poor prognostic indicators for outcome include use of tobacco and presence of a mandible fracture. Open reduction and internal fixation were found to bear a higher complication rate only in mandible fractures. While choice of treatment carries a statistically significant association with outcome, social variables, including gender, tobacco use, intoxication, and low socioeconomic status, produce dramatic worsening of both injury incidence and outcome.

Severe blunt assault injuries at Auckland Hospital

The incidence and nature of severe blunt assault injury in the Auckland region was assessed by a retrospective review over a 2-year period. Approximately 14000 charges of assault (excluding paediatric and sexual assault) were laid during this period. A total of 1035 people were admitted to hospital. Of 331 patients admitted to one hospital, 35 patients were admitted via the resuscitation room after severe assault; of these, two died. Of these patients, 33 were male and 19 of 21 ethanol levels measured were greater than 17 mol l . Head and facial injuries were the most frequent.

Trauma and the full moon: a waning theory.

There exists a popular belief in the causal relationship between the moon's phase and the incidence of major trauma. In this retrospective study we reviewed 1,444 trauma victims admitted to the hospital during one calendar year. Full moons were defined as three-day periods in the 29.531-day lunar cycle, with the middle day being described in the world almanac as the full moon. Victims of violence included those patients sustaining blunt assault, gunshot wounds, and stabbings. There was no statistical difference in number of trauma admissions between the full moon, 129 patients per 36 days (mean, 3.58), and nonfull moon days, 1,315 patients per 330 days (mean, 3.98). Mortality rate, 5.4% versus 10.3%; mean Injury Severity Score, 13 versus 15; and mean length of stay, ten versus 12 days, were not significantly different during the full moon and nonfull moon days. Victims of violence were admitted at a similar frequency on full moon, 16 patients per 36 days (mean, 0.444), and nonfull moon days, 183 patients per 330 days (mean, 0.555). We conclude that the belief in the deleterious effects of the full moon on major trauma is statistically unfounded.

An analysis of proximal phalangeal fractures

To attain accurate reduction in the proximal phalanx as opposed to the other phalanges, we have found open reduction and internal fixation to be necessary in a large proportion of cases in our series. The cause of injury in the majority of cases was blunt assault, possibly a unique spectrum in this type of trial and a probable influence on treatment choice. There were 50 fractured proximal phalanges in 40 patients analyzed according to their modes of treatment, immobilization, and functional results. Treatment for proximal phalangeal fractures have been structured according to these results.
