Elevated intrathoracic pressure could affect pulmonary vascular pressure measurements and influence pulmonary hypertension (PH) diagnosis and classification. Esophageal pressure (Pes) measurement adjusts for the increase in intrathoracic pressure, better reflecting the pulmonary hemodynamics in patients with obesity. ⋯ Adjusting pulmonary hemodynamics for Pes in patients with obesity leads to a pronounced reduction in the number of patients who receive a diagnosis of postcapillary PH. Measuring Pes should be considered in patients with obesity, particularly those with elevated PAWP.

Observational Study
Prognostic Value of Echocardiographic Variables Before and After Initiation of Parenteral Prostacyclin Therapy: An Observational Study.
Echocardiographic parameters are used as prognostic markers in patients with pulmonary arterial hypertension (PAH) receiving parenteral (IV or subcutaneous [IV/SC]) prostacyclin therapy. However, data on how posttreatment echocardiographic results associate with outcomes are limited. ⋯ Echocardiographic variables improved following IV/SC therapy, and multiple echocardiographic measures associated significantly with survival, particularly when reassessed after at least 90 days of therapy. RA size in particular may be useful in prognostication in follow-up of patients with PAH on IV/SC therapy.

A 63-year-old Japanese woman with no medical history presented as an outside hospital transfer for further management of acute hypoxemic respiratory failure. Per her family, the patient had developed a rash and intermittent shortness of breath 2 months prior to hospital presentation. The rash was described as an erythematous maculopapular rash located on her proximal arms, chest, and upper eyelids. ⋯ She was subsequently started on 80 mg of IV methylprednisolone three times daily and transferred to our institution for further management. The patient arrived from the outside hospital receiving deep sedation and paralysis. Despite maximal ventilator settings, the patient remained hypoxemic and developed shock requiring multiple vasopressors.

A 35-year-old man presented to the ED with a 7-day history of fever, asthenia, and cough. He had previously received a 3-day course of amoxicillin and clavulanic acid (1 g tid po) and then ceftriaxone (1 g IM once per day) prescribed by his general practitioner with no substantial benefit. He was an active smoker (11.2 pack/y), without known allergy-related syndromes and any important reports in his medical history.

A previously healthy 57-year-old man presented to the ED with altered mental status and severe shortness of breath. He was found to be in acute hypercapnic respiratory failure and required admission to the ICU. He reported the following: a 4-month history of progressive shortness of breath; left-sided chest pain; cough productive of brown, foul-smelling sputum; and weight loss. ⋯ His last visit to Ethiopia was in 2009, and he denied any other recent travel or exposure to TB. There was no history to suggest immune compromise. He had not seen a physician in many years and never established medical care in the United States.
