The purpose of this study was to analyze the efficacy of corticosteroids in severe acute decompensation of chronic obstructive pulmonary disease requiring mechanical ventilation and intensive care unit (ICU) admission. Pairwise retrospective case-control study with 1:1 matching. Patients were defined as cases when they received corticosteroids and as controls when they did not received any steroids. ⋯ However, systemic corticosteroid therapy was associated with a significant increase in a reduction in the duration of mechanical ventilation (P = 0.004) and a trend toward a shorter length of ICU stay (P = 0.053). Although the authors detected no significant difference in mortality rate at the time of discharge between steroid and streroid-free patients, this study confirms that systemic corticosteroid therapy in patients with chronic obstructive pulmonary disease exacerbations requiring mechanical ventilation is associated with a significant reduction in the duration of mechanical ventilation. Other studies are needed on this subject.

An initial carbamazepine concentration may initially be supratherapeutic, therapeutic, or even subtherapeutic only to persist to rise over time. The aim of this study was to report the frequency of toxic carbamazepine concentrations continuing to rise and to estimate how often an initially therapeutic or subtherapeutic concentration misrepresents the potential toxicity of an acute carbamazepine overdose. An 8-year retrospective search of all carbamazepine exposures reported to the Illinois Poison Center (January 1, 2001 through December 31, 2008) was reviewed. ⋯ Additionally, several patients with initial levels of therapeutic or subtherapeutic concentration later became comatose and required ventilator management. Initial serum carbamazepine concentrations can be misleading. Serial measurements documenting a declining carbamazepine concentration or prolonged observation are recommended when managing these overdoses.

Obstructive sleep apnea is a common, chronic disorder characterized by the cessation or reduction in airflow due to periodic mechanical obstruction of the upper airway passage during sleep. Symptoms and signs of sleep apnea include daytime sleepiness, fatigue, poor concentration, snoring, resuscitative snorts, and related occupational accidents. Sleep apnea is classified into 3 types based on its severity and management varies accordingly. ⋯ Positive airway pressure is the preferred treatment modality and can be delivered via 3 different modes. Oral appliances are of 3 types and are generally indicated in mild to moderate obstructive sleep apnea. Surgery is a final therapeutic option that focuses on the removal of excessive tissue from different sites of the pharyngeal airway.

Treatment options for massive and submassive pulmonary embolus may include hemodynamic support, fibrinolysis, anticoagulation, and thrombectomy. Selection of the appropriate therapy requires scrutiny of the patient's hemodynamic status, preexisting conditions, risk of complications, and availability of services at the treatment center. This article illustrates a case of successful fibrinolysis and thrombectomy in a woman with massive pulmonary embolus. A discussion of the indications, benefits, and disadvantages of several pharmacologic, radiologic, and surgical interventions considered in pulmonary embolus will follow.

Food and Drug Administration (FDA) advisory committees have a significant influence on patterns of clinical practice worldwide. Recent guidance to the committees by the FDA has focused on attempting to eliminate sources of bias due to committee voting procedures. Nevertheless, major sources of social influence have not been addressed. ⋯ Speaking order and voting order are both determined by seating location. We therefore conclude that voting behavior on FDA expert advisory committees is strongly associated with seating location. This suggests the presence of a possible social dynamic that is not addressed by existing FDA committee procedures.
