Cytomegalovirus bearing in children with sensorineural hearing losses.

The rate of bearing of cytomegalovirus, CMV, has been estimated in children suffering from inborn or newborn types of a sensorineural hearing loss of hard-to-severe degrees. The test group comprised 15 hearing-loss children of 3-6 years of age. The control group included accidentally selected 30 healthy children of the same age without any hearing complains.

Association between the cytomegalovirus seroprevalence and hearing loss in early childhood.

This study was designed to evaluate the association between the seroprevalence of CMV with the hearing loss among preschool children. A case-control study has been performed in Tbilisi, Digomi Inclusive Education Centre for children with hearing loss. The cohort of 15 children with SNHL was studied for HCMV specific IgG and IgM antibodies concentration in the blood.

[Electron microscopy in the differential diagnosis of chronic lympholeukemia and differentiated (lymphocytic) lymphosarcoma in the leukemization stage].

By electron microscopy, globular structures of varying size and moderate electron density were revealed in cells of peripheral blood, bone marrow and lymph nodes in patients with differentiated (lymphocytic) lymphosarcoma at the stage of leukemization, which were located in both cytoplasm of lymphoid cells and intercellular spaces. Plasmocyte-like cells with bizarre outlines of rough endoplasmatic reticulum were also observed in patients with leukemized lymphosarcoma. The above globular structures are not observed in patients with chronic lymphocytic leukemia.

The ability of the two cultures Penicillium sp. and Fusarium sp. to synthesize extracellular pectolytic enzymes was investigated.
