Oral manifestations of infections of infections due to varicella zoster virus in otherwise healthy children.

Varicella zoster virus (VZV) causes varicella (or chickenpox) and establishes latency in nerve ganglia after the primary infection. The reactivation of virus later in life can cause mono- or polyneuropathy. The cranial nerves most commonly involved are five (herpes zoster or shingles), six, seven eight, nine and ten.

Immunohistochemical study of four histologic types of parotid gland pleomorphic adenoma.

The immunohistochemical detection of lysozyme, lactoferrin, a1-antichymotrypsin and a1-antitrypsin was used to investigate the marker expression and histogenesis of each one of four histologic types of 20 parotid gland pleomorphic adenomas. Moreover, 10 adult and 20 neonate parotid glands were studied. The immunohistochemical analysis revealed that tumor types 1 and 2 are nearly identical immunohistochemically while types 3 and 4 differ from one another, as well as from types 1 and 2.

[Comparative immunohistochemical study of lysozyme and lactoferrin in human neonate and adult parotid glands].

Lysozyme and lactoferrin, substances of the non-specific defense system of the salivary glands, were studied in normal human parotid glands of neonates and adults using the immunoperoxidase method. To our knowledge, the immunohistochemical detection and distribution of lysozyme and lactoferrin in neonate parotid glands have not been previously reported. In neonate parotid glands, a monotonous positive reaction for lysozyme was found in the acini, in the intercalated ducts and in a few cells of large ducts.

An immunohistochemical study of normal human neonate and adult parotid gland tissue. Detection of lysozyme, lactoferrin, a1-antichymotrypsin, a1-antitrypsin and carcinoembryonic antigen.

The immunohistochemical detection and distribution of lysozyme (Ly), Lactoferrin (Lf), a1-Antichymotrypsin (a1-AChy), a1-Antitrypsin (a1-AT) and Carcinoembryonic antigen (CEA) were studied in neonate and adult parotid gland tissue, using the peroxidase-antiperoxidase (PAP) method. Ly stain in neonates extended into acini, intercalated ducts and occasional cells of large ducts, whereas in adults Ly was usually confined to the intercalated ducts. The distribution pattern of Lf in neonates varied considerably between individual glands showing three staining patterns.

[Reiter's syndrome oral manifestations].

Reiter's syndrome is characterized by arthritis, non-gonococcal urethritis, conjunctivitis and mucocutaneous lesions. Oral lesions occur in 20-40% of the cases. They appear as papules and ulcerations on the buccal mucosa, gingiva and lips.
