Impairment of Inspiratory Muscle Function after COVID-19.

Background: Persistent symptoms after acute coronavirus-disease-2019 (COVID-19) are common, and there is no significant correlation with the severity of the acute disease. In long-COVID (persistent symptoms >4 weeks after acute COVID-19), respiratory symptoms are frequent, but lung function testing shows only mild changes that do not explain the symptoms. Although COVID-19 may lead to an impairment of the peripheral nervous system and skeletal muscles, respiratory muscle function has not been examined in this setting.

[Transarterial chemoembolization of hepatocellular carcinoma].

Transarterial chemoembolization (TACE) is used as palliative and neoadjuvant treatment for patients with hepatocellular carcinoma (HCC). TACE should be offered as palliative treatment to patients with intermediate stage large or multinodular HCC if no curative treatment option is available by resection or thermoablation and if extrahepatic metastases and tumor infiltration of main portal and systemic veins has been excluded. TACE is possible only in patients with preserved liver function (Child-Pugh A-B, best up to 7 points) and with good performance status (ECOG 0).

Targeted Temperature Management for Subarachnoid Hemorrhage: Excellent Outcome After Severe Vasospasm-A Case Series.

Targeted temperature management (TTM) might improve outcome of patients with severe subarachnoid hemorrhage (SAH) in which vasospasm, delayed cerebral ischemia (DCI), and increased intracranial pressure (ICP) are frequent and severe complications. A series of patients ( = 3) with severe aneurysmatic SAH were treated by TTM if they developed ICP crisis and/or severe vasospasm diagnosed by angiography. Once these complications were detected, body core temperature (BCT) was rapidly decreased to 35°C or 33°C, if necessary.

Safety and Feasibility of Chemoembolization with Doxorubicin-Loaded Small Calibrated Microspheres in Patients with Hepatocellular Carcinoma: Results of the MIRACLE I Prospective Multicenter Study.

Purpose: The MIRACLE I pilot study was designed as a preliminary investigation of safety and efficacy of Embozene TANDEM microspheres loaded with doxorubicin for treatment of locally untreatable (i.e., unresectable and not suitable for local thermal ablation) hepatocellular carcinoma (HCC).

German guideline on the diagnosis and treatment of peripheral artery disease - a comprehensive update 2016.

The prevalence of peripheral artery disease (PAD) is increasing worldwide and is strongly age-related, affecting about 20 % of Germans over 70 years of age. Recent advances in endovascular and surgical techniques as well as clinical study results on comparative treatment methods strengthened the need for a comprehensive review of the published evidence for diagnosis, management, and prevention of PAD. The interdisciplinary guideline exclusively covers distal aorta and atherosclerotic lower extremity artery disease.

The Diagnosis and Treatment of Peripheral Arterial Vascular Disease.

Background: In peripheral arterial occlusive disease (PAOD), arterial stenosis or occlusion impairs perfusion in the territory of the distal portion of the aorta and the iliac and leg arteries. In Germany, the prevalence of PAOD rises with age, reaching 20% among persons over age 70.

Methods: This guideline was prepared by a collaboration of 22 medical specialty societies and two patient self-help organizations on the basis of pertinent publications that were retrieved by a systematic search in PubMed for articles that appeared from 2008 to April 2014, with a subsequent update to May 2015.

Transcatheter arterial chemoembolization (TACE) of colorectal cancer liver metastases by irinotecan-eluting microspheres in a salvage patient population.

Purpose: This prospective study evaluated the effectiveness and safety of TACE using irinotecan loaded superabsorbent polymer (SAP) microspheres for treatment of colorectal cancer liver metastases (CCLM) in a salvage setting of patients.

Methods: A total of 71 TACE procedures were performed in 29 patients with liver only or liver-dominant CCLM. In all patients, systemic chemotherapy before TACE had failed.

Current concepts in transarterial chemoembolization of hepatocellular carcinoma.

Transarterial chemoembolization (TACE) has the potential to improve survival in patients with intermediate stage hepatocellular carcinoma (HCC). Careful selection of patients is mandatory to gain survival benefit and safe quality of life. Basic principles of TACE in HCC include selective treatment via intrahepatic and extrahepatic arteries, proper management of side effects and continuation of treatment guided by imaging.

Radiofrequency ablation of solitary pancreatic insulinoma in a patient with episodes of severe hypoglycemia.

Insulinomas are rare neuroendocrine tumors of the pancreas. Therapy of first choice is the surgical resection or enucleation. In cases of metastases or in patients with high surgical risk, medical therapy with diazoxide or octreotide is an alternative.

Efficacy of radiologic screening for distant metastases and second primaries in newly diagnosed patients with head and neck cancer.

Objectives: Detection of distant metastases and second primary tumors in newly diagnosed patients with head and neck cancer has usually a major effect on prognosis but does not always influence clinical management. This must be considered when radiologic screening investigations are used. The present study particularly evaluates how often additional neoplastic lesions detected by screening had an impact on therapy.

Uterine peristaltic activity and the development of endometriosis.

Peristaltic activity of the nonpregnant uterus serves fundamental functions in the early process of reproduction, such as directed transport of spermatozoa into the tube ipsilateral to the dominant follicle, high fundal implantation of the embryo, and, possibly, retrograde menstruation. Hyperperistalsis of the uterus is significantly associated with the development of endometriosis and adenomyosis. In women with hyperperistalsis, fragments of basal endometrium are detached during menstruation and transported into the peritoneal cavity.

Application of poly-lactide-co-glycolide-microspheres in the transarterial chemoembolization in an animal model of hepatocellular carcinoma.

Aim: To introduce an animal model of hepatocellular carcinoma (HCC) in ACI-rats, and to evaluate the therapeutic effects of Poly-lactide-co-glycolide (Plcg) -microspheres in the transarterial chemoembolization (TACE) in this model, as well the value of this model in the experiments of interventional therapy.

Methods: Subcapsular implantation of a solid Morris Hepatoma 3 924A (1 mm(3)) in the livers was carried out in 11 male ACI-rats. The tumor volume (V1) was measured by magnetic resonance imaging (MRI) (13 days after implantation).

Transjugular intrahepatic portosystemic shunts in children with biliary atresia.

Purpose: We retrospectively evaluated the technical and long-term clinical results of transjugular intrahepatic portosystemic shunts (TIPS) in children with portal hypertension and biliary atresia (BA).

Methods: Nine children with BA and recurrent bleeding from esophagogastric and/or intestinal varices were treated by TIPS at the age of 34-156 months and followed-up in two centers. Different types of stents were used.
