Clinical Trial
Low-dose almitrine bismesylate in the treatment of hypoxemia due to chronic obstructive pulmonary disease.
Assessment of acute and chronic effects of low-dose almitrine bismesylate (AB) in stable chronic obstructive pulmonary disease (COPD). ⋯ Low-dose AB therapy, 75 mg daily, resulted in sustained elevation of arterial oxygen tension in hypoxemic patients with COPD. Although pulmonary artery pressure increased transiently after the first dose, it remained unchanged with long-term treatment despite persistent improvement of pulmonary gas exchange.(ABSTRACT TRUNCATED AT 250 WORDS)

Fungal endocarditis is considered an absolute indication for valve replacement surgery. We describe the successful medical treatment of recurrent Candida parapsilosis candidemia with sequential treatment with amphotericin B and fluconazole in a patient with probable prosthetic valve endocarditis. Because of the presumed effectiveness of amphotericin B and fluconazole in the treatment of this patient, medical therapy should be considered as potentially useful in the treatment of recurrent C parapsilosis fungemia or endocarditis or both.

Randomized Controlled Trial Comparative Study Clinical Trial
Regional mucus transport following unproductive cough and forced expiration technique in patients with airways obstruction.
It has previously been shown that unproductive coughing in both healthy subjects and patients with airways obstruction is not effective in clearing lung secretions. This study investigates the regional mucus transport in a group of subjects with airways obstruction who failed to expectorate following instructed cough and forced expiration technique. Fourteen patients (mean +/- SEM age: 68 +/- 2 years) with airways obstruction (mean +/- SEM percent predicted. ⋯ There were no differences in regional radioaerosol clearance between cough and forced expiration. However, both cough and forced expiration resulted in significant clearance compared with control for all regions with the exception of the forced expiration in the outer region. To our knowledge, this study is the first to demonstrate that unproductive cough and forced expiration result in movement of secretions proximally from all regions of the lung in patients with airways obstruction.

A high proportion of patients admitted to a medical emergency department due to chest pain are directly sent home, since the initial suspicion of acute myocardial infarction (AMI) can be quickly ruled out. ⋯ Patients who came to a medical emergency department due to chest pain, and who were sent home, had a low risk of death and development of infarction during the following year. Survivors after 1 year do, however, more frequently report emotional and psychosomatic symptoms than survivors of AMI.

To examine the incidence, clinical impact, and predictors of reintubation following unplanned extubation (UE) in ICU patients. ⋯ Unplanned extubation can result in serious complications; however, about half the patients who have UE can be safely observed without immediate reintubation. Selected clinical factors, which are readily available from standard ICU records for the 24-h period prior to UE, may be useful to predict the likelihood of reintubation.
