Hemodialysis is a life-saving method for patients with acute and chronic kidney failure. This treatment requires sufficiently large and safe vascular access. Ensuring optimal vascular access is therefore a prerequisite and an integral part of the care of these patients. In addition to commonly known vascular approaches such as non-tunnelized or tunneled hemodialysis catheters and AV fistulas, less well-known methods are also available, such as a translumbar or directly surgically inserted hemodialysis catheter into the right atrium. However, these alternative approaches are the only, life-saving alternative for some patients. The ambition of this review article is to offer a comprehensive view of the available options for vascular access, the algorithm for its selection and solutions to the most common complications in clinical practice.

Osteoarthritis is one of the most common diseases of the joints and spine and is characterized by degenerative changes starting in the cartilage. Joint changes cause pain, stiffness, swelling, and a loss of normal joint function. Several international recommendations address the choice of treatment methods for osteoarthritis. However, because there is still no effective causal treatment leading to a remission of the disease, this is a complex issue. Even the possibilities of effective but safe treatment of pain, which is the most common problem accompanying osteoarthritis, are very limited. All current international recommendations for the treatment of osteoarthritis agree on the crucial role of non-pharmacological treatment and the choice of a comprehensive approach to the treatment of osteoarthritis. Pharmacological treatment includes non-opioid analgesics, opioids, symptomatic slow-acting osteoarthritis drugs, or intra-articular corticosteroids. A new trend is to maximize the potential of existing analgesics by combining them. Using drugs from different classes with complementary mechanisms of action provides a better opportunity for effective analgesia at reduced doses of individual agents. The use of fixed combinations is also advantageous.

The brain is among the target organs of hypertension. Patients with hypertension have a higher risk of developing stroke as well as experiencing a decline in cognitive functions and dementia. Changes in the white matter and atrophy of the grey matter of the brain induced by high blood pressure develop insidiously since the onset of hypertension, even in young individuals. The effect of high blood pressure on the vessel wall cumulates in time; therefore, hypertension in younger people implies an increased risk of dementia in older age. Hypertension in young age cannot be considered a benign condition. Hypertension in middle age increases the risk of dementia by 61 %. Consistent and early hypertension control can reverse the adverse development towards dementia and lack of self-sufficiency in the patient. Data comparing individual antihypertensive drugs in terms of preventing dementia are scarce. However, renin angiotensin system blockers have been found to protect against Alzheimer's disease more than other classes of antihypertensive drugs. To achieve rapid and effective hypertension control, a combination of antihypertensive drugs is usually required. Using a fixed-dose triple combination of perindopril, indapamide, and amlodipine, blood pressure targets of < 130/80 mm Hg can be achieved within three months in 93 % of patients.

Multimorbidity - the simultaneous presence of several chronic diseases - is very common in the critically ill patients. Its prevalence is roughly 40-85 % and continues to increase further. Certain chronic diseases such as diabetes, obesity, chronic heart, pulmonary, liver or kidney disease and malignancy are associated with higher risk of developing serious acute complications and therefore the possible need for intensive care. This review summarizes and discusses selected specifics of critical care for multimorbid patients.

Vertigo/dizziness or balance disorders are among the most common patients complaints in emergency clinics. Up to 25% of them are potentially life-threatening, especially cardiovascular or cerebrovascular events. The combination of a careful history taking (triggers, duration of difficulties, associated symptoms) and the performance of a basic vestibular examination (nystagmus, oculomotor, head impulse test, positional maneuvers, standing and walking examination) leads to a reliable differentiation of central and peripheral vestibular etiology. Standardized diagnostic algorithms (HINTS, HINTS+, STANDING) are used to identify high-risk patients requiring urgent care. Imaging methods must be interpreted with caution to their low sensitivity in acute phase (sensitivity of non-contrast brain CT for ischemia in the posterior cranial fossa is only 16%, MRI of the brain is false negative in up to 20% of cases in stroke patients in the first 48 hours).

Multiple sclerosis (MS) is a chronic autoimmune disease of the central nervous system, mainly affecting young adults. Factors positively influencing its course include early antiinflammatory treatment and the influencing of other comorbidities. The most common comorbidities occurring in MS patients with a higher frequency than in the general population are neurological, psychiatric, cardiovascular, metabolic and autoimmune. Just as comorbidity compensation affects the course of MS, in some cases, MS decompensation is associated with a worse course of associated diseases. Due to common risk factors and partially shared immunopathogenesis, treatment covering multiple conditions can be used, especially for some autoimmune diseases. On the other hand, some drugs may potentiate the development of other autoimmunity or disorder. A special topic is the side effects and complications of treatment (especially infections and malignancies) of disease-modifying therapies used in patients with MS. However, the potential treatment discontinuation carries significant risks and should always be discussed with the MS specialist. Therefore, close interdisciplinary collaboration is crucial.

Diabetes mellitus is a disease characterized by chronic hyperglycaemia due to an absolute or relative lack of insulin. The disease mainly affects the nervous system, and the urological complications themselves develop on the basis of these disorders. Urological patients with diabetes present in ambulance with manifestations of common urological diseases, but also suffer from complications of the urinary system or genital organs that are specific for diabetic patient. Usually, these complications go unrecognized for a long time or manifest only non-specifically. But they are often life-threatening for patients. Treatment does not consist only in urological stabilization, but stabilization of the diabetes itself is also necessary. It can be said that diabetes increases the risk of urological problems, and on the contrary, urological problems (especially inflammation) can lead to decompensation of the patient's diabetes.

Hereditary angioedema (HAE) is a rare, inborn disease manifested with recurrent attacks of angioedema. They can affect the skin and subcutaneous tissue, mucous membranes (gastrointestinal, respiratory, and uropoietic tracts), and submucous tissue. Women in reproductive age require specific management of the disease regarding both the course of the disease and treatment options. It is not only the treatment in female patients that is specific, but also the situations (pregnancy, breastfeeding). We present a case report of the initial use of a subcutaneous C1 inhibitor in the long-term prophylaxis of HAE attacks in two pregnant patients.

Point-of-Care ultrasonography (POCUS) is a method defined as a targeted ultrasound examination of patients with acute symptoms or syndromes that can be diagnosed by a healthcare worker at a site. The aim is to answer a specific diagnostic or therapeutic question or to ease the therapeutic procedure. Recently in Europe, there has been an increase in implementing POCUS in many medical fields including primary health care. The Czech Society of General Practice (SVL ČLS JEP) has for several years been watching the use of POCUS in primary care in many European countries. In August 2020, the committee of the Czech Society of General Practice charged the Working Group for ultrasound in primary care to start a project POCUS iGP - POCUS Implementation in General Practice aiming for the implementation of POCUS into daily practice in general medicine. An ultrasound device is required, as well as setting up the education and training courses with follow up courses and a consensual curriculum of skills, securing quality control mechanisms, proving with scientific evidence the reliability of POCUS when provided by GPs and setting up the final rules of competency and payment for performance. The current international trend of patient centred care in primary health settings and increasing competencies of GPs emphasises a need to implement new point of care diagnostic methods. One of which is point of care ultrasonography. Scientific outcomes and published data from primary care and other fields of medicine show that even doctors who do not work in radiology departments are after a relatively short course able to independently provide POCUS examinations with high reliability. Establishment of the Czech Multidisciplinary Task Force Group for standards, education and research in Pointof- Care ultrasound support development of the POCUS implementation.
