Asthma and Its Symptoms
Asthma is a chronic respiratory disease characterized by inflammation of the bronchi, which can cause a variety of unpleasant symptoms. During the disease, the smooth muscle of the bronchi may exhibit spasmodic contractions, leading to narrowing of the airways. Additionally, swelling of the mucous membranes and increased mucus production further obstruct airflow, resulting in various breathing difficulties. Asthma typically occurs in children and young adults, but it can also appear in adulthood, particularly without an allergic background. Recognizing and diagnosing the disease is crucial for appropriate treatment. Asthmatic symptoms encompass a wide spectrum, ranging from mild breathing difficulties to severe attacks. The triggers for asthma can vary, including allergens, respiratory…

Schizophrenia – There Are Many Misunderstandings in Public Perception
Schizophrenia is a complex mental illness surrounded by many misconceptions. The public often confuses schizophrenia with other mental disorders, such as multiple personality disorder, which can severely distort social understanding and the situation of patients. Schizophrenia does not actually mean a split in personality but rather a condition in which the patient loses their sense of reality, often struggling with delusions and hallucinations. Schizophrenia affects not only the lives of patients but also the lives of their family members and immediate surroundings. Those affected often withdraw from society, and their relationship with everyday activities also changes. Disseminating accurate information is essential for understanding the illness and providing appropriate support. Thus,…

When do antidepressant medications start to take effect?
The use of antidepressants in the treatment of mental health issues, such as depression, is widespread. These medications influence mood and well-being through their effects on the central nervous system. It is important to understand that the effects of antidepressants are not immediate but develop gradually. Patients often become impatient at the beginning of treatment, expecting quick results, but in reality, the brain requires time to adapt to the new medications. Understanding the mechanism of action of these drugs can help patients realistically evaluate their expectations. Individuals struggling with depression need to pay attention to the signs they experience during treatment, as these can help assess its success. Restoring the…

Allergy to Chemical Substances
The modern world exposes us to various chemicals that affect our quality of life and health. These substances can be found in the air, our food and drinks, as well as in our workplaces and homes. As technology advances, the presence of chemicals increasingly becomes a part of our daily lives. Although most chemicals are not hazardous, there are those that can cause sensitivity and allergic reactions when present in high concentrations or with long-term exposure. Traffic fumes, cigarette smoke, and other environmental factors can further enhance this sensitivity. The best method to prevent allergic reactions is to avoid potentially harmful chemicals, but this is nearly impossible in practice, as…

Bladder-ureter reflux (VUR)
The vesicoureteral reflux (VUR) is a urinary tract disorder that is particularly common among infants and children. This condition is based on an anomaly of the urinary tract, which causes urine to flow back into the ureter and even into the renal pelvis. As a result of the reflux, children may experience frequent urinary tract infections, which can lead to serious long-term health problems if not properly treated. The anatomical abnormalities underlying VUR are related to the positioning and closing mechanism of the ureter. Normally, urine flow through the ureter is unidirectional, but this mechanism can be disrupted due to reflux. Treatment of the condition is of significant importance, as…

Skin Bruises – The Appearance and Characteristics of ITP
The decrease in platelet count of unknown origin and the associated bleeding skin symptoms have long intrigued the scientific community. This phenomenon is particularly associated with a dramatic drop in platelet numbers, which can cause a range of unpleasant symptoms. This problematic condition is medically known as immune thrombocytopenia (ITP) and is characterized by bruising and small bleeding spots appearing on the skin. During the course of the disease, the platelet count can decrease significantly, leading to severe consequences such as intracranial or cerebral bleeding. Although the diagnosis of ITP is complex, the disease is often linked to antibodies that bind to the platelets, thereby hindering their normal function. As…

When do we experience hallucinations?
Hallucinations are perceptual disorders in which an individual experiences things that do not actually exist. During this phenomenon, the person may perceive sights, sounds, tastes, or even smells, all without those things being present in reality. Hallucinations can often be so vivid that those affected do not doubt the reality of what they are experiencing. They may cling to their perceptions even when their surroundings deny their existence, which can lead to serious social and psychological consequences. These disorders can arise for various reasons and are often associated with mental disorders such as schizophrenia or other psychoses. Hallucinations may not only indicate a mental health condition but can also appear…

The Contemporary History of AIDS
AIDS, one of the world’s largest public health crises, emerged as a result of a unique and complex series of events. The HIV virus, which is the primary cause of AIDS, spread through the human population via an extraordinarily complicated route. The roots of this story trace back deep into the rainforests of Central Africa, where chimpanzees and other primates live. The transmission of viruses carried by these primates to humans occurred as a result of a series of chance events, involving numerous contributing factors. Before the emergence of AIDS, the virus had been present for decades, but it burst into public consciousness in the early 1980s when unusual cases…

Signs, Therapies, and Prevention Methods of Malaria
Malaria is an infectious disease that remains a significant global problem today, particularly in tropical climate regions. The background of the disease’s development is characterized by the humid air typical of marshy areas, which is also reflected in the term “bad air.” This illness is transmitted by mosquitoes, especially those species that are active at night and during twilight. The pathogens, belonging to the genus Plasmodium, enter the body through the bites of mosquitoes that suck human blood. In this process, humans act as intermediate hosts, where the pathogens undergo a complex developmental cycle. The occurrence of the disease has reached alarming proportions, as a significant portion of the world’s…

Pulmonary Hypertension: Elevated Blood Pressure in the Pulmonary Circulation
Pulmonary hypertension is a condition characterized by increased blood pressure in the pulmonary arteries. This phenomenon can develop for various reasons, and the diagnosis is typically made based on an echocardiogram. However, for an accurate diagnosis, specialized cardiac catheterization may also be used, though this is rarely necessary. The increased pressure in the pulmonary arteries can be temporary, but in many cases, it can persist, leading to pulmonary hypertension. Often, an underlying disease affects the cardiovascular system, such as congenital or acquired abnormalities, or reduced compliance of the left ventricle. Treating these underlying conditions can improve the patient’s status. The most common form of pulmonary hypertension is pulmonary arterial hypertension…
