A pulmonologist is a doctor who specializes in the diagnosis and treatment of lung diseases.

Pseudoallergy is a body's reaction that is similar to an allergic reaction, but does not involve the immune system. It is a direct reaction to the perpetrator (e.g., additives, dyes, preservatives in food), which triggers the release of histamine and other inflammatory substances from cells in the body. Symptoms of pseudoallergy can include hives, swelling, breathing difficulties, digestive problems, and in some cases anaphylactic shock. Because pseudoallergies do not involve antibodies, allergy tests usually do not show any reaction. Treatment usually involves avoiding triggers and using antihistamines to relieve symptoms.

Protopic is a medicinal ointment, which contains the active ingredient tacrolimus. It is available in the form of 0.03% ointment and 0.1% ointment. It belongs to the group of calcineurin inhibitors. It falls into the category of immunosuppressants. It is primarily used for the treatment of atopic dermatitis.

PRICK tests or skin prick tests are tests used to detect sensitizations or allergies to a certain allergen. It's about proving hypersensitivity mediated by IgE. The test is performed by first drawing a grid on the forearm, onto which drops of individual allergens are applied, then the skin is minimally damaged over a drop of allergen with a tiny plastic stick (there is no bleeding). After this, wait approximately 20 minutes, then the test is read. If a wheal appears on the test field and the area itches, the test has proven sensitization to a certain allergen.

Each lung lobe is surrounded by two serous membranes, the visceral pleura (visceral pleura) and the parietal pleura (parietal pleura), which enclose a sponge-like pleural (pleural) cavity. Pleural effusion is a condition in which fluid accumulates between the two layers of the pleura.

Pityriasis-like scaling is a form of skin scaling, where the scales are very fine and resemble bran (pityriasis in Greek means bran). Pityriasis-like scaling can occur in various skin diseases.

PEF is an acronym for "peak expiratory flow". It refers to the maximum flow of air during exhalation (after a prior deep inhalation). It is measured in liters per minute. It is usually measured with a handheld meter that looks like a mouthpiece, through which the person forcefully exhales (after a prior deep inhalation). PEF is commonly used to monitor asthma treatment.
