Page 7 of 73 SIALADENS
Secretion of saliva is carried out by 3 couples of glands: parotid, submaxillary and hypoglossal. Secret of parotid glands serous; it contains amylase and secretory imkhmunoglobulin A (IgA). Submaxillary glands emit the mixed serous and mucous liquid, and hypoglossal — transparent slime. The volume and composition of saliva depends on extent of secretory stimulation of each of 3 couples of glands and is defined by many local and general factors.
Except for epidemic parotitis, a disease of sialadens occur at children seldom. Bilateral increase in submaxillary glands happens at a mucoviscidosis, insufficiency of food and a bad asthmatic attack (quickly). The frequent vomitings and aspiration of emetic masses taking place at an achalasia can be followed by increase in parotid glands.
Hypersalivation at babies is observed until they did not create the muscular reflexes defining swallowing and a smykaniye of lips. Late hypersalivation is observed at a teething. At some mentally retarded children continuous hypersalivation is noted. Plentiful salivation arises in anticipation of meal or pain, at the irritating processes in a mouth, nausea, reception of mercury drugs, and also at some diseases of a nervous system, for example at encephalitis or a chorea.
Decrease in secretion of saliva under the influence of some drugs, diseases or radiation, as a rule, leads to the strengthened destruction of teeth. Saliva not only has the obvious clearing effect, but, apparently, contains substances which form the acellular film covering an adamantine substance of tooth. This film defines interaction of enamel with the liquids washing it; in the absence of a film caries violently develops. In such cases the oral cavity irrigation is recommended by artificial fluorinated saliva.
Xerostomia. Temporary dryness in a mouth is noted at fever, dehydration, the use of such drugs as derivative a fenotiazina, atropine and other anticholinergic drugs. the inborn xerostomia is characterized by dimness and dryness of a mucous membrane of an oral cavity. Apply Pilocarpinum to treatment of this state.
Recurrent parotitis. The hypostasis of a parotid gland recuring idiopathic can arise at the healthy child. Usually perhaps simultaneous or consecutive defeat of both glands increases only one iron, but. At some children 10 and more palindromias are noted. At an aggravation there is small pain, hypostasis is limited to area of gland and 2 — 3 weeks last. Total or partial disappearance of hypostasis happens spontaneously. Aggravations arise in spring time more often.
Purulent parotitis. Purulent parotitis can be primary disease or complication of parotitis of other origin; Most often the activator is golden staphylococcus. Process is usually unilateral, is followed by fever; gland Is edematous, dense and painful.
Recurrent parotitis does not demand treatment; it is important not to confuse it with purulent parotitis at which it is necessary to apply those antibacterial agents to which the activators sowed from pus are sensitive. Material for crops is received from a channel of a sialaden or at its surgical drainage.
Mikulich's illness. This idiopathic bilateral painless increase in parotid sialadens and lacrimal glands which is followed by dryness of mucous membranes of a mouth and lack of tears. The similar syndrome can be observed at tuberculosis, leukoses and a lymphosarcoma.
Cyst of hypoglossal gland (ranul, frog tumor). The cyst proceeding from a sialaden in hypoglossal area gives to a neck the outward reminding a frog; the name "frog tumour" is explained by it. The large soft education containing slime appears at the mouth basis. The disease can arise at any age, including chest. The cyst needs to be ekstirpirovat, and to remove a channel of gland in an oral cavity.
