Papilloma of the conjunctiva on the leg of the manifestation can be early, after birth, or years later. Papillomas, which can be numerous and sometimes bilateral, are most often located on the palpebral conjunctiva, vault or flesh.
Cervical papilloma refers to the rare form of background diseases, characterized by focal proliferation of the stroma and multilayered planar epithelium with its cornification. In the appearance of papillomas a certain role is played by viral infections and chlamydia.
Papillary syringoadenoma (syn: papillary ekkrinnaya adenoma, papillary syringocystadenoma, papillary syringocystadenomatous nevus, papillary tubular adenoma is a rare tumor, it is localized more often on the skin of the distal parts of the extremities in the form of a clearly delimited nodule of a hemispherical shape, sometimes with a semi-translucent wall, 0.5- 1.5 cm.
Papillary hydradenoma is a benign tumor of apocrine sweat glands. The causes and pathogenesis of papillary skin hydradenoma are unknown.
The causes and pathogenesis of spontaneous is not fully understood. Of great importance are the transferred infections, trauma, drug intolerance, pancreatic lesions, etc. A certain role is played by the processes of lipid peroxidation.
The main symptom of a panic disorder is a recurring panic attack. Panic attacks are characterized by sudden intense anxiety, accompanied by at least four autonomic or cognitive symptoms. A panic attack is characterized by rapid development, anxiety culminates in a few minutes.
Panic disorder occurs if the child has recurrent, frequent (at least once a week) panic attacks. Panic attacks are individual episodes, lasting approximately 20 minutes, during which the child develops somatic or psychological symptoms. Panic disorder can develop with or without agoraphobia.
A panic attack is a sudden onset of a brief attack of severe discomfort or fear, accompanied by somatic or cognitive symptoms
This concept includes hypothalamic-pituitary insufficiency, postpartum hypopituitarism - Shiena syndrome, pituitary cachexia - Simmonds disease. In 1974, M. Simmonds described postpartum, septic-embolic necrosis of the anterior lobe of the pituitary gland with a fatal outcome in the state of severe cachexia and catastrophically developed senile involution of organs and tissues.
The most common acute pancreatitis occurs elderly and less often - in old age with increased pressure in the pancreatic ducts, which leads to damage to the acinous cells and their membranes with the release of pancreatic enzymes into the parenchyma, interlobular connective and adipose tissue of the pancreas.
Pancreatitis is an inflammation of the pancreas. There are two main forms - acute and chronic pancreatitis.
In most cases, they are found in the intestine in the area of the ileocecal angle and in the bronchi, while they are rarely functioning. Pancreatic carcinoid is capable of secreting virtually all peptides that are characteristic of ortho- and para- endocrine neoplasms.
Tuberculous pancreas lesion is very rare, even in patients with active pulmonary tuberculosis, it is detected, according to different authors, in only 0.5-2% of cases. Tuberculous mycobacteria enter the pancreas with hematogenous, lymphogenic or contact (from affected neighboring organs) pathway.
Pancreatic sarcoma is extremely rare, to date, about 200 cases of pancreatic sarcoma have been described in specialized medical literature (judging by the statistics of a number of authors).
In a number of cases, especially with pronounced widespread atherosclerotic vascular lesions in elderly and senile patients, thromboses and pancreatic infarctions sometimes occur. They may be caused by small thrombi and embolism from the left atrium with heart defects (stenosis of the left atrioventricular orifice), infectious endocarditis, embolism from atheromatous plaque, etc.
Typically, according to their origin and morphological features, there are four types of pancreatic cysts. The first type is ontogenetic cysts, which are a developmental defect, often such cysts are multiple and often combine with polycystosis of other organs (lungs, kidneys, liver, etc.), thus representing congenital polycystic disease. Cysts are usually lined with a single-row cubic epithelium, and the contents are serous and do not contain enzymes.
The defeat of the pancreas in atherosclerosis is observed mainly in people older than 60 years, less often and at a younger age - mostly among people with alcoholism. In this case, sclerotic changes develop in the pancreas, its excretory and endocrine functions are violated.
Pancreatic cancer is found, according to various sources, in 1-7% of all cancers; more often in persons older than 50 years, predominantly in men.
Panaritium treatment pursues the goal, which consists in complete and sustained relief of inflammatory phenomena while minimizing functional and aesthetic negative consequences, and in some cases, the risk of fatal outcome.
Palmar-plantar keratoderma is a large group of diseases, very different in their morphology. Some of them are an independent disease, others are part of numerous syndromes, while others represent one of the manifestations of diffuse keratoses.
