Systemic vasculitis is a heterogeneous group of diseases, the main morphological feature of which is inflammation of the vascular wall, and the spectrum of their clinical manifestations depends on the type, size, localization of the affected vessels and the severity of the associated inflammatory changes.
Systemic scleroderma is a polysyndrome autoimmune disease characterized by progressive fibrosis and widespread vascular pathology by the type of obliterating microangiopathy underlying the generalized Raynaud's syndrome, skin and internal organs (lung, heart, digestive tract, kidney).
Systemic lupus erythematosus is a systemic autoimmune disease of unknown etiology, which is based on a genetically determined impairment of immune regulation that determines the formation of organonesspecific antibodies to cell nucleogen antigens with the development of immune inflammation in the tissues of many organs.
Diseases of the liver often manifest common symptoms and disorders.
Syringoma (syn: multiple syringoadenoma, eruptive hydra-cone) is a developmental defect of the eccrine sweat gland, similar in structure to the protocol department in the upper part of the dermis.
Primary syphilis manifested by chancre is very rare and occurs as a result of accidental infection of the auricle or external auditory canal with skin damage or with a kiss.
Syphilitic hepatitis occurs in 4-6% of patients with late visceral syphilis. Syphilitic lesions of the liver can be congenital and acquired.
Syphilis is a chronic infectious disease transmitted predominantly through sexual intercourse. It is characterized by periodicity of the course and various clinical manifestations.
Syphilis of urogenital organs is revealed in all parts of the globe. Most often they suffer from young people aged 20 to 30 years, although in recent years, there has been a clear tendency to a sharp "rejuvenation" of the infection with an increase in the incidence among adolescents 14-16 years and younger.
Syphilis of the salivary glands (lyus salivary glands) is a chronic venereal disease caused by pale treponema, characterized by damage to the skin, mucous membranes, internal organs and the nervous system.
Syphilis of the pancreas can be congenital and acquired. It is believed that a specific lesion of the pancreas is found in almost 10-20% of children suffering from congenital syphilis; more often affects the head of the pancreas. Syphilitic changes in the pancreas are found in the fetus as early as the second half of pregnancy.
Syphilis of the nose is divided into acquired and congenital. Acquired nasal syphilis can appear in all three periods - primary, secondary and tertiary. The greatest practical importance is syphilis of the nose in the tertiary period.
Syphilis of the esophagus - the disease is not so frequent, occurs in all stages of this venereal disease, but is most often manifested in the Tertiary period.
If in the first half of the XX century. Syphilis of the pharynx was extremely rare, in the last decade of the last century and at the beginning of the 21st century. The number of this localization of syphilis is steadily increasing, as is the total number of genital forms of this venereal disease. Due to the large morphological diversity of tissues that make up the throat, its lesions with syphilis differ by a number of features that are not inherent in other localization of this disease.
Syphilis of the larynx is observed much less often than the nose or pharynx. Very rarely the larynx is affected by congenital syphilis.
In HIV-infected patients with syphilis, unusual serological reactions are observed. Most reports indicate titres higher than expected, but false negative results and a delay in the manifestation of sero-reactivity have also been reported.
All women in early pregnancy should be screened for syphilis. In populations where optimal prenatal monitoring is not possible, screening with the RPR test and treatment (with positive test results) is performed at the time of pregnancy.
Bejel (endemic syphilis, Arabic syphilis) is a chronic infectious disease that occurs mainly among children and is manifested by erythematous-papular rashes on the skin, lesions of the mucous membranes, bones, joints and cartilages.
Synovitis of the knee joint is a common disease that is associated with inflammation of the joint connective tissue (synovial membrane).
Syndromes of chromosomal deletions are a consequence of the loss of a part of the chromosome. At the same time there is a tendency to develop severe congenital malformations and a significant delay in mental and physical development.
