Review Case Reports
Use of an impedance threshold device to treat severe hypotension in a pregnant woman: case report and review of the literature.
Impedance threshold device technology harnesses the patient's normal physiological mechanisms to increase circulation during hypotensive crises. We report the first clinical use of one version of this device on a spontaneously breathing hypotensive pregnant woman. ⋯ In this case report, the multiple physiological effects of inspiration through -7 cmH2O resistance helped this pregnant hypotensive patient to rapidly and noninvasively restore adequate perfusion and reduced the duration of her hypotensive episode. To our knowledge, this is the first report of this technology in a pregnant hypotensive but spontaneously breathing patient.

Review Case Reports
Febrile illness in a young traveler: dengue Fever and its complications.
Dengue fever, a tropical disease once confined mostly to endemic areas in developing countries, is becoming more prevalent. Globalization has led to an increased incidence of the virus both in foreign travelers returning home and local outbreaks in traditionally nonendemic areas, such as the southern United States and southern Europe. Advances in diagnostic tests, therapies, and vaccines for dengue virus have been limited, but research is ongoing. ⋯ Emergency physicians should consider dengue fever in patients with acute febrile illnesses, especially among those with recent travel.

Colloids are widely used for fluid resuscitation in patients with sepsis. But the optimal type of fluid remains unclear. ⋯ There is no evidence that one colloid solution is more effective and safer than another for fluid resuscitation in sepsis. The severity score is improved in HES, but the confidence intervals are wide.
