Currently established prognostic models in traumatic brain injury (TBI) include noncontrast computed tomography (CT) which is insensitive to early perfusion alterations associated with secondary brain injury. Perfusion CT (PCT) on the other hand offers insight into early perfusion abnormalities. We hypothesized that adding CT perfusion and permeability data to the established outcome predictors improves the performance of the prognostic model.

A prospective cohort study of consecutive 50 adult patients with head injury and Glasgow Coma Scale score of 12 or less was performed at a single Level 1 Trauma Centre. Perfusion CT was added to routine control CT 12 hours to 24 hours after admission. Region of interest analysis was performed in six major vascular territories on perfusion and permeability parametric maps. Glasgow Outcome Scale (GOS) was used 6 months later to categorize patients' functional outcomes to favorable (GOS score > 3) or unfavorable (GOS score ≤ 3). We defined core prognostic model, conc study, level III.Abdominal vascular trauma accounts for a small percentage of military and a moderate percentage of civilian trauma, affecting all age ranges and impacting young adult males most frequently. Penetrating causes are more frequent than blunt in adults, while blunt mechanisms are more common among pediatric populations. High rates of associated injuries, bleeding, and hemorrhagic shock ensure that despite advances in both diagnostic and therapeutic technologies, immediate open surgical repair remains the mainstay of treatment for traumatic abdominal vascular injuries. Due to their devastating nature, abdominal vascular injuries remain a significant source of morbidity and mortality among trauma patients. The American Association for the Surgery of Trauma (AAST) in conjunction with the World Society of Emergency Surgery (WSES) seek to summarize the literature to date and provide guidelines on the presentation, diagnosis, and treatment of abdominal vascular injuries. TC-S 7009 LEVEL OF EVIDENCE.The peripheral arteries and veins of the extremities are among the most commonly injured vessels in both civilian and military vascular trauma. Blunt causes are more frequent than penetrating except during military conflicts and in certain geographic areas. Physical exam and simple bedside investigations of pulse pressures are key in early identification of these injuries. In stable patients with equivocal physical exams, computed tomography angiograms have become the mainstay of screening and diagnosis. Immediate open surgical repair remains the first line therapy in most patients. However, advances in endovascular therapies and more widespread availability of this technology have resulted in an increase in the range of injuries and frequency of utilization of minimally invasive treatments for vascular injuries in stable patients. Prevention of and early detection and treatment of compartment syndrome remain essential in the recovery of patients with significant peripheral vascular injuries. The decision to perform amputation in patients with mangled extremities remains difficult with few clear indicators. The American Association for the Surgery of Trauma (AAST) in conjunction with the World Society of Emergency Surgery (WSES) seek to summarize the literature to date and provide guidelines on the presentation, diagnosis, and treatment of peripheral vascular injuries.

Clinical characteristics and timing associated with nonsurgical recovery of upper extremity function in acute flaccid myelitis are unknown.

A single-institution retrospective case series was analyzed to describe clinical features of acute flaccid myelitis diagnosed between October of 2013 and December of 2016. Patients were consecutively sampled children with a diagnosis of acute flaccid myelitis who were referred to a hand surgeon. Patient factors and initial severity of paralysis were compared with upper extremity muscle strength outcomes using the Medical Research Council scale every 3 months up to 18 months after onset.

Twenty-two patients with acute flaccid myelitis (aged 2 to 16 years) were studied. Proximal upper extremity musculature was more frequently and severely affected, with 56 percent of patients affected bilaterally. Functional recovery of all muscle groups (≥M3) in an individual limb was observed in 43 percent of upper extremities within 3 months. Additional complete limb recovery to greater than or equal to M3 after 3 months was rarely observed. Extraplexal paralysis, including spinal accessory (72 percent), glossopharyngeal/hypoglossal (28 percent), lower extremity (28 percent), facial (22 percent), and phrenic nerves (17 percent), was correlated with greater severity of upper extremity paralysis and decreased spontaneous recovery. There was no correlation between severity of paralysis or recovery and patient characteristics, including age, sex, comorbidities, prodromal symptoms, or time to paralysis.

Spontaneous functional limb recovery, if present, occurred early, within 3 months of the onset of paralysis. The authors recommend that patients without signs of early recovery warrant consideration for early surgical intervention and referral to a hand surgeon or other specialist in peripheral nerve injury.

The purpose of this study was for the authors to describe their patient selection, surgical technique, and results with the alar rotation flap for surgical defects of the nasal ala.

The authors performed a retrospective analysis of all alar rotation flaps performed between June of 2006 and February of 2019. Three hundred ninety-four patients were identified, and follow-up encounters were reviewed to assess for complications and need for revision procedures.

The alar rotation flap was performed on 394 patients over a 13-year period. The mean defect size was 9.3 ± 2.8 mm by 7.2 ± 2.3 mm. Three hundred nineteen patients (81 percent) were evaluated postoperatively, with a mean average duration of follow-up of 2.3 years (range, 6 days to 11.9 years). Complications included hemorrhagic crust along the incision line [n = 9 (3 percent)], flap edema [n = 7 (2 percent)], internal nasal valve dysfunction [n = 3 (1 percent)], depressed surgical scar [n = 2 (1 percent)], hematoma [n = 1 (0.5 percent)], and paresthesia [n = 1 (0.
