Basic Bronchoscopy Competence Achieved by a Nationwide One-day Simulation-based Training.

Background: In 2020, a mandatory, nationwide 1-day bronchoscopy simulation-based training (SBT) course was implemented for novice pulmonology residents in the Netherlands. This pretest-posttest study was the first to evaluate the effectiveness of such a nationwide course in improving residents' simulated basic bronchoscopy skills.

Methods: After passing a theoretical test, residents followed a 1-day SBT course, available in 7 centers, where they practiced their bronchoscopy skills step-by-step on a virtual reality simulator under pulmonologist supervision.

A 37-Year-Old Woman With Recurrent Hemoptysis.

A 37-year-old woman presented with a 2-month history of recurrent hemoptysis and coughing. Her symptoms started 2 months after the delivery of her third child. In total, she endured four episodes of hemoptysis.

Reproducibility of hypercapnic ventilatory response measurements with steady-state and rebreathing methods.

In this study, the hypercapnic ventilatory response (HCVR) was measured, defined as the ventilation response to carbon dioxide tension ( ). We investigated which method, rebreathing or steady-state, is most suitable for measurement of the HCVR in healthy subjects, primarily based on reproducibility. Secondary outcome parameters were subject experience and duration.

Safety and efficacy of sequential chemotherapy with carboplatin plus gemcitabine followed by weekly paclitaxel in advanced non-small cell lung cancer.

Background: Improving survival in non-small cell lung cancer (NSCLC) will require new strategies or new drugs. Sequential administration of conventional non-cross-resistant cytotoxic drugs offers an opportunity to increase drug diversity while maintaining dose intensity. This Phase II trial was designed to assess the efficacy and feasibility of such a regimen in advanced NSCLC.

Etanercept-related extensive pulmonary nodulosis in a patient with rheumatoid arthritis.

Although nodulosis is a common extraarticular manifestation of rheumatoid arthritis, accelerated pulmonary nodulosis is a rare event. The etiology of rheumatoid nodules is still unknown. Nodulosis is not necessarily associated with active joint inflammation, suggesting different pathogenic mechanisms for nodule formation and synovial tissue inflammation.

Pulmonary sclerosing hemangioma detected by fluorodeoxyglucose positron emission tomography in familial adenomatous polyposis: report of a case.

We present a 53-year-old female suffering from familial adenomatous polyposis, who was found to have a positive nodus, lateral to the hilus of the left lung, on routine FDG-PET scan. This lesion was found to be a sclerosing hemangioma. We found an aberrant beta-catenin expression on immunohistochemical staining, suggesting that sclerosing hemangioma and familial adenomatous polyposis share the same pathophysiology.

Comparison of acetazolamide and medroxyprogesterone as respiratory stimulants in hypercapnic patients with COPD.

Background: Acetazolamide and medroxyprogesterone acetate (MPA) are two respiratory stimulants that can be used in patients with stable hypercapnic COPD.

Design And Methods: The effects of acetazolamide, 250 mg bid, and MPA, 30 mg bid, on daytime and nighttime blood gas values and the influences on the hypercapnic and hypoxic ventilatory and mouth occlusion pressure (P(0.1)) at 100 ms response were studied in a crossover design in 12 hypercapnic patients with stable COPD (FEV(1), 33 +/- 4% predicted [mean +/- SEM]).
