Cerebral artery bypass surgery makes it possible to improve or replace cerebral circulation by bringing blood flow from extracranial arteries into the cerebral arteries or by creating new flow routes between cerebral arteries. Cerebral artery bypass operations play an important role in the treatment of the rare moyamoya disease causing cerebral artery stenosis and disturbances of the cerebral circulation and in the treatment of cerebral aneurysms that are unamenable to treatment with traditional microsurgical or endovascular techniques. Compared with conservative therapy, bypass surgery does, however, not seem beneficial in the prevention of strokes and hemodynamic disturbances of the cerebral circulation associated with atherosclerotic occlusion of the carotid artery.

The diagnosis of appendicitis is based on the typical symptom picture and clinical findings. Laboratory studies, in which leukocytosis and an increased neutrophil count are typical findings, can be used in support of the diagnosis. ⋯ In cases of uncertain clinical diagnosis, appendicitis can be found fairly reliably by using computed tomography scanning of the abdomen. Urgent appendectomy is the current care for appendicitis.

Painful neuropathy is a common complication of diabetes and causes disability and impaired quality of life. Treatment of neuropathy aims at pain relief, improved function and quality of life and avoidance of foot ulcers. Progression of neuropathy is prevented with good glycemic control and treatment of the risk factors of atherosclerosis. ⋯ Comorbidities, concomitant medications and possible contraindications are taken into account in drug selection. Since treatment with a single agent does not provide sufficient pain relief, combination of two drugs with different mechanism of action is recommended. Most patients need long-term treatment.

Hepatopulmonary syndrome (HPS) is characterized by the triad of liver disease, intrapulmonary vascular dilatation and arterial deoxygenation. Mediating factors are tumor necrosis factor a, endothelin 1 and nitric oxide. Typical symptom is an increase in dyspnea while in standing position, orthodeoxia. ⋯ The blood flow distribution to the lungs is changed as the pulmonary vascular tone is altered. Diagnosis is based on the evidence of liver disease, hypoxemia and pulmonary vascular shunt detected by the so-called bubble test. Liver transplantation is currently the only efficient therapeutic option.

Review
[The use of direct oral anticoagulants (DOAC) in the treatment atrial fibrillation (AF) patients].
AF is associated with the risk of stroke, and this risk is exceedingly high in elderly patients (> or = 75 years) and in patients after a stroke. DOACs are appropriate anticoagulants for AF patients without mechanical heart valves or mitral stenosis. Patients on DOACs do not require routine monitoring of coagulation, but need regular follow-up visits including an assessment of therapy adherence, thromboembolic and bleeding events and measurements of hemoglobin and platelets values as well as renal and liver function.
