[Clostridioides difficile - New Insights and Therapy Recommendations].
After an increase in Clostridioides difficile infections (CDI) until 2013 due to epidemic ribotypes such as 027 and 078, CDI incidence in Germany is now declining, as confirmed by recent epidemiological data. Despite this success through antimicrobial stewardship and hospital hygiene, the burden of disease remains high, especially in older patients (>65 years) with comorbidities. The main risk factor for CDI is the use of broad-spectrum antibiotics, which disrupt the gut microbiota, allowing C. difficile colonization. ⋯ For the treatment of recurrent CDI, the new guidelines also include the use of the monoclonal antibody bezlotoxumab. In addition, a new oral microbiome therapy, SER-109 (capsules containing purified Firmicutes spores), which showed promising results in a phase 3 study, may provide an easy-to-administer alternative to fecal microbiota transplantation. Hopes for a well-performing toxoid vaccine for primary and secondary prevention of CDI have unfortunately not been fulfilled in the CLOVER trial.

Pulse oximetry has high sensitivity but low specificity for detecting hypoxemia. Arterial blood gas analyses are the gold standard for monitoring O2 therapy. Venous blood gas analyses should not be used in this setting. ⋯ These patients should always be monitored with arterial blood gases-in the case of peripheral VA-ECMO on the right arm and downstream of the oxygenator. HIGH-FLOW OXYGEN THERAPY FOR ACUTE HYPERCAPNIC RESPIRATORY FAILURE: High-flow oxygen therapy (HFNC) was not associated with reduced in-hospital mortality compared with conventional O2 in a meta-analysis of predominantly patients with acute hypoxemia (type I respiratory failure), although intubation rates were reduced. Also, in acute hypercapnic respiratory failure (type II), HFNC with high flow rates is not inferior to noninvasive ventilation (NIV).

We report on a 66-year-old patient who had had painful swelling of his left big toe for about 9 months with subjectively stopped growth. ⋯ As in the case presented, retronychia is often misdiagnosed. The knowledge of groundbreaking clinical and anamnestic parameters and the correct therapy options allows a quick, inexpensive, and long-term successful treatment.

Review[Clinical Application Examples of a Next-Generation Sequencing based Multi-Genepanel Analysis].
This review provides an overview of clinically useful applications of a next-generation sequencing (NGS)-based multi-gene panel testing strategy in the areas of oncology, hereditary tumor syndromes, and hematology. In the case of solid tumors (e.g. lung carcinoma, colon-rectal carcinoma), the detection of somatic mutations contributes not only to a better diagnostic but also therapeutic stratification of those affected. ⋯ Another useful indication for a multi-gene panel diagnostics and prognosis assessment are acute and chronic myeloid diseases. The criteria of the WHO-classification and the European LeukemiaNet-prognosis system for acute myeloid leukemia can only be met by a multi-gene panel test strategy.

Randomized Controlled Trial[Endovascular Therapy for Peripheral Artery Disease - Therapeutic Options for Treatment of Severe Calcification].
Calcified lesions are a major limitation of endovascular therapy of peripheral artery disease. Recently published studies evaluating the impact of lithotripsy (Disrupt III) and directional atherectomy (REALITY) as vessel preparation devices for calcified femoro-popliteal lesions prior to the final treatment with drug-coated balloons (DCB). Disrupt III, a randomized controlled trial comparing lithotripsy and regular balloon angioplasty for vessel preparation prior to DCB, and REALITY, a single-arm study of directional atherectomy prior to DCB angioplasty resulted in low provisional stent and dissection rates. ⋯ Importantly, both vessel preparation strategies resulted in a low rate of post-procedural residual stenosis of >30%, the major predictor for loss of patency following DCB angioplasty in long-term. Lithotripsy is an emerging therapy concept for vessel preparation of calcified pelvic arteries prior to trans-femoral aortic valve implantation. In summary, vessel preparation of calcified arterial lesions by improving vessel compliance or reducing the plaque load represent promising technical methods reducing provisional stent rates and improving longer-term outcomes.
