Abstract

ZusammenfassungEin 38-jähriger Patient wurde aufgrund einer zunehmenden Verschlechterung des Allgemeinzustandes und einer Kachexie stationär aufgenommen. Bildmorphologisch ergab sich bei einschmelzenden Rundherden und einer kavernösen Formation der Verdacht auf eine Mykobakteriose, sodass die Indikation zu einer Bronchoskopie gestellt wurde. In der Bronchoskopie gelang tatsächlich der Nachweis einer nicht tuberkulösen Mykobakteriose. Als Zufallsbefund zeigte sich im Mittellappenbronchus eine weißliche polypöse Schleimhautveränderung. Histologisch war ein Granularzelltumor (GZT) nachweisbar. Der GZT ist ein seltener Tumor, der an verschiedenen anatomischen Lokalisationen auftreten kann. In der Lunge kann er klinisch durch eine bronchiale Obstruktion manifest werden, bildgebend als Rundherd oder Infiltrat bzw. Atelektase oder als Zufallsbefund in einer Bronchoskopie auffallen. Therapie der 1. Wahl ist die chirurgische Entfernung.

Abstract

A 38 years old patient presented with a progressive reduction of his general condition and weight loss. Chest imaging revealed consolidations and cavities suggesting a mycobacterial infection. For further diagnosis, a bronchoscopy was performed. In fact, a nontuberculous mycobacterial infection was found. As an incidental finding, we saw a white polypoid tumor in the middle lobe bronchus. The histology of this tumor revealed a granular cell tumor (GCT). The GCT is a rare tumor entity which occurs at different anatomical locations. In the lungs, the GCT may become symptomatic as it can cause bronchial obstruction. In chest imaging, it can manifest as infiltration, atelectasis or nodule. Likewise, GCT can be found as an incidental finding in bronchoscopy. First choice treatment is surgical resection of the tumor.Ein 38-jähriger Patient wurde aufgrund einer zunehmenden Verschlechterung des Allgemeinzustandes und einer Kachexie stationär aufgenommen.

Abstract

Introduction: Patients after cardiac arrest (CA) treated with extracorporeal cardiopulmonary resuscitation (eCPR) evidence high mortality. Recently, women were reported to evidence even worse outcomes after CA. However, sex-specific data on CA patients treated with eCPR are lacking. We therefore aimed to evaluate potential sex differences in risk distribution, management, and outcomes in patients treated with eCPR., Methods: Sixty-four patients - 16 females (25%) and 48 males (75%) - were included in this retrospective analysis. Two propensity scores were calculated on sex using multivariable logistic regression. Propensity score 1 included baseline characteristics only, and propensity score 2 included the previous variables plus pH as well as lactate concentration. Univariable and multivariable logistic regression models were used to assess associations with the endpoints., Results: The distribution of risk factors and baseline characteristics showed no sex-specific differences. Sex was neither associated with mortality nor with bad neurological outcomes, and remained so after adjustment for both propensity scores. Baseline lactate (adjust odds ratio [aOR], 1.18; 95% confidence interval [CI], 1.02-1.38; P=.03), lactate after 6 hours (aOR, 1.23; 95% CI, 1.04-1.45; P=.01), and lactate clearance at 6 hours (aOR, 0.979; 95% CI, 0.959-0.999; P=.04) were independently associated with 30-day mortality. Higher lactate clearance after 6 hours was associated with lower rates of bad Glasgow Outcomes Scale both in univariable (OR, 0.967; 95% CI, 0.941-0.991; P=.02) and multivariable logistic regression models (aOR, 0.967; 95% CI, 0.941-0.994; P=.02)., Conclusion: There were no sex-specific outcome differences in patients treated with eCPR. Both lactate concentration and lactate clearance could help with the selection of patients for inclusion in eCPR trials.
