Neurologically Intact Survival after Bihemispheric Penetrating Head Trauma: A Case Report.

BACKGROUND: Patients with penetrating head trauma that crosses the midline of the brain have a high mortality rate; most die in the prehospital setting or during initial resuscitative efforts. However, surviving patients are often neurologically intact and several factors other than bullet path, including post-resuscitation Glasgow Coma Scale, age, and pupillary abnormalities, must be considered in aggregate when prognosticating patients. CASE REPORT: We present a case of an 18-year-old man who presented unresponsive after a single gunshot wound to the head that traversed the bilateral hemispheres. The patient was managed with standard care and without surgical intervention. He was discharged from the hospital neurologically intact 2 weeks after his injury. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Patients with such apparently devastating injuries are at risk of premature termination of aggressive resuscitative efforts based on clinician bias that these efforts are futile and that patients cannot recover to a neurologically meaningful outcome. Our case reminds clinicians that patients with severe injury patterns with bihemispheric involvement can recover with good outcomes, and that bullet path is only one variable among multiple that must be considered to predict clinical outcome.

Diagnosis and Management of Monkeypox: A Review for the Emergency Clinician.

The outbreak of monkeypox in May and June 2022 is the largest outside of central and western Africa since the 2003 outbreak in the United States. Monkeypox, like smallpox, is caused by an orthopoxvirus, though its clinical manifestations tend to be less severe. It is characterized by a prodromal flu-like illness with lymphadenopathy followed by a centrifugally spreading rash, sometimes involving the face, palms, soles, and oral mucosa. Although the vast majority of cases resolve with symptomatic management, a small number of patients can suffer severe outcomes including, but not limited to, secondary bacterial skin infections, pneumonitis, ocular sequelae, encephalitis, hypovolemia, and death. Local, state, and federal health authorities should be involved in the care of people under investigation for this illness. With confirmed cases worldwide and the possibility of community spread, emergency clinicians need to be aware of the manifestations and management of this disease, both to treat those with the disease as well as to provide education to those exposed and at risk of infection.

The influence of alternative instruction on 6-min walk test distance.

BACKGROUND: The goal of the 6-min walk test (6MWT) is to enable patients to walk "as far as possible" as a measure of their functional ability. The impact of the specific walk instructions on patient 6MWT performance is unknown. METHODS: Patients with pulmonary arterial hypertension (PAH), idiopathic pulmonary fibrosis (IPF), and other forms of interstitial lung disease (ILD) were recruited to perform four identical 6MWTs with one differing instructional phrase. The standard instruction to walk "as far as possible" was substituted in random order with "as fast as possible," "at your normal pace," or "at a leisurely pace." RESULTS: Twenty-four patients (10 with PAH, eight with IPF, six with other ILD) were enrolled and completed all four 6MWTs. Patients attained the greatest distance with the fast instruction, exceeding the standard instruction distance by a mean of 52.7 m (P < .001). The mean difference between the fast and standard walks was 41.5 m in the PAH group, 66.5 m in the IPF group, and 53 m in the other ILD group. CONCLUSIONS: Patients do not walk as far as they are able with the standard American Thoracic Society instruction for 6MWT. Changing the wording from "far" to "fast" may facilitate a better effort and greater distance during the test. It is possible that this modified 6MWT instruction may result in improved accuracy and reproducibility, thereby enhancing its clinical and research trial usefulness.

The red cell distribution width as a prognostic indicator in idiopathic pulmonary fibrosis.

BACKGROUND: The course of idiopathic pulmonary fibrosis (IPF) is characterized by variable patterns of disease progression. The red cell distribution width (RDW) is a parameter that is routinely reported with all CBC counts. We sought to test the prognostic usefulness of this parameter in a well-defined cohort of patients with IPF. METHODS: CBCs, demographics, and pulmonary function data from patients with IPF evaluated between January 1997 and June 2011 were collated. Patient outcomes were ascertained from the program's database and the Social Security Death Index. RESULTS: There were 319 patients with IPF evaluated in whom baseline CBCs were available. The range in the RDW was 11.9 to 21.9 (median 14.1). There were 228 subjects with RDW values ≤ 15 (normal) and 91 patients with RDW values > 15. Patients with normal RDW values had a median survival of 43.1 months compared with 16.3 months for those whose RDW was > 15 (P = .001). There were 198 patients with available serial RDW data. Those patients who had a change in the RDW of less or greater than +0.010/mo had median survivals of 43.0 and 23.9 months, respectively (P = .0246). CONCLUSIONS: The RDW is a readily available laboratory test result that may provide important, independent prognostic information at baseline and follow-up in patients with IPF. Further studies are warranted to validate this as a biomarker for IPF outcomes, as well as to define the biologic basis for this association.
