[The physicochemical properties of the mixed saliva and parotid secretion of patients with chronic parenchymatous parotitis and of persons who have a history of earlier acute parotitis].

Eighty-five patients with chronic parenchymatous parotitis and 73 convalescents after epidemic or acute nonepidemic parotitis were examined for their secretory function and some physicochemical characteristics of mixed saliva and parotid secretion (secretion rate, pH, viscosity, transparency, electrokinetic properties). A significant reduction of salivary secretion volume and rate were detected, as were pH shift to the acid direction and increased viscosity of both saliva and parotid secretion, reduced transparency and increased electric conductivity in the patients with chronic parenchymatous parotitis, more marked in those with an active course of the disease. Such changes were absent in convalescents after epidemic or acute nonepidemic parotitis. This permits a conclusion that none of these two conditions may be responsible for the development of a chronic inflammation of the parotid gland. The detected changes in physicochemical parameters of the saliva in chronic parenchymatous parotitis supplement the known data on the pathogenesis of this condition and may be used in the diagnosis and prediction of the course and outcome of sialadenitis. The authors emphasize the desirability of therapeutic and prophylactic measures during remissions of chronic parenchymatous parotitis.

[Immunizing and immunomodulating activity of a wild epidemic parotitis virus at a parotitis infection focus].

The immune status of 18 children previously vaccinated or not with live parotitis vaccine and living in a focus of parotitis was tested over time. Specific antibodies were found in the blood sera or nasal secretion of 88.9% children by follow-up days 10-20, and memory antigen-reactive cells were forming in 55.6%. Functional temporary T-immunodeficiency was observed at the same period in 66.7% children. Although there were no cases of clinically apparent epidemic parotitis, immunologic studies confirmed the circulation of wild type virus. Immunologic studies detected 2 cases of inapparent course of epidemic parotitis.

Immunoglobulin-containing plasma cells in chronic parotitis and malignant lymphomas of the parotid gland. Comparing immunocytochemical observations of frequency and localization.

IgA-containing plasma cells in the periductal gland tissue are part of the special secretory immune system of the salivary glands. The reaction of Ig-containing plasma cells (localization, frequency, specific Ig-content) was analyzed by the indirect immunoperoxidase method in chronic recurrent parotitis (9 cases), chronic myoepithelial parotitis (benign lymphoepithelial lesion, Sjögren's syndrome; 8 cases), and malignant lymphoma associated with chronic myoepithelial parotitis (11 cases). The following results were obtained: 1. In chronic recurrent parotitis, parallel to the increase in IgA in the salivary secretion, a marked multiplication of IgA-containing plasma cells was found in the inflammatory infiltrate and the remaining non-inflamed periductal parenchyma of the parotid gland. In the marginal zone of inflammation, a slight increase of IgG-containing plasma cells was also observed. 2. In chronic myoepithelial parotitis, the total plasma cellular infiltration was slightly less distinct than in chronic recurrent parotitis. The most remarkable increase in Ig-containing plasma cells developed in the marginal zones--away from the myoepithelial cellular islands--as well as in the area of ductular proliferations, and was characterized by a strong increase of IgG-containing plasma cells. At the same time, a slight increase of IgM-containing plasma cells was observed. No plasma cells were found in the myoepithelial cellular islands. 3. In the malignant lymphomas associated with myoepithelial parotitis, which were mainly highly differentiated lymphomas (immunocytomas, centrocytic-centroblastic lymphomas) and rarely poorly differentiated immunoblastic lymphomas, there was a distinct decrease of IgG-containing plasma cells when compared with the numbers in this group without lymphoma. The differing degrees of prevalence and Ig-content of the plasma cells partly describe the change taking place in the local secretory immune system of the parotid gland. The possible relationships between chronic recurrent parotitis and auto-immune myoepithelial parotitis on one hand and the stages of transition (prelymphoma) to malignant lymphoma on the other, are discussed.

[Role of parotitis virus in the development of insulin-dependent diabetes mellitus].

Viral infection is one of the factors provoking the development of insulin-dependent diabetes mellitus (IDDM). Epidemic parotitis more frequently than other infections is connected with IDDM manifestations, but the results of examinations of convalescents after epidemic parotitis and of patients with newly diagnosed IDDM are contradictory. Parotitis viruses are believed to injure pancreatic beta-cells and trigger on the autoimmune process in carriers of certain antigens. In none of the 200 cases of IDDM manifestation a relationship with epidemic parotitis was established and none of the 268 convalescents after epidemic parotitis developed IDDM. Screening for antibodies to epidemic parotitis virus carried out in 61 patients with newly detected IDDM revealed low antibody titers in the majority (83.3%); HLA-B8 antigen was detected in 23% of these examinees. In the group of subjects with persistent high antibody titers and their diagnostic increment or reduction HLA-B8 antigen was found in only 12.5%. These results do not permit a conclusion on the relationship between IDDM manifestation and parotitis infection.

The possible significance of cytomegaloviral parotitis in infant and early childhood deaths.

OBJECTIVE: To determine whether cytomegaloviral (CMV) parotitis reflects a disseminated disease that increases vulnerability to unexpected death. DESIGN: Necropsy-based cross-sectional study comparing incidences of brain stem microglial nodules and visceral lymphocytic infiltrates in patients with and without CMV parotitis. SUBJECTS: One hundred twelve infants and young children comprising a study group of 40 individuals with CMV parotitis (including 32 whose deaths remained unexplained) and two comparison groups comprising 40 explained and 32 unexplained deaths. MAIN OUTCOME MEASURES: Incidence and variation with age of brain stem microglial nodules and lymphocytic infiltrates in liver and kidneys. RESULTS: Brain stem microglial nodules and lymphocytic infiltrates in liver and kidneys are strongly associated with CMV parotitis; their incidence diminishes with increasing age. CONCLUSIONS: Disseminated disease frequently accompanies CMV parotitis in infants. The resolution of brain stem microglial nodules precedes that of parotitis. Active and previous brain stem involvement may increase vulnerability to unexpected death.

Drug-induced parotitis.

Drug-induced parotitis is a relatively uncommon adverse drug reaction. Most of the data on drug-induced parotitis consist of isolated case reports with few attempts at rechallenge to confirm the aetiology. Phenylbutazone and oxyphenbutazone have a significant number of reports suggesting that these drugs may be implicated in causing parotitis. Antipsychotics, particularly thioridazine, have been associated with parotitis. Most of these reports relate the anticholinergic oral drying as a predisposing factor in the development of a parotid gland infection. There is inadequate literature on the histamine (H2) receptor blockers, interferon-alpha, doxycycline, trimipramine, nifedipine, methyldopa, nitrofurantoin, nicardipine, isoproterenol or ritodrine to link them as aetiological agents in the development of parotitis.

[The results of an immunoepidemiological examination of foci of epidemic parotitis].

The immunoepidemiological survey of 54 foci of epidemic parotitis showed that the epidemiological effectiveness index at preschool institutions, equal to 2.7, was essentially higher than at schools (2.1). The significant difference (t = 3.35) in the epidemiological effectiveness indices was due to the presence of a large number of persons having had inapparent and faintly pronounced forms of epidemic parotitis among school children, as well as due to more close contacts of children with the foci of infection at preschool institutions. The study showed that among children immunized with some lots of parotitis vaccine elevated morbidity in epidemic parotitis was registered. In the foci of infection children, immunized in the presence of low initial titers of specific hemagglutinins in their sera, responded by a booster effect with different duration of stimulation of antibody formation. The hemagglutinin titer of 1:20 was shown to protect children from epidemic parotitis.

[Characteristics of parotitis virus, isolated in Siberia].

Two strains of parotitis virus were isolated from patients with clinical symptoms of the disease in epidemiological screening which was carried out during an outbreak of epidemic parotitis in the village of Koltsovo in 1994. The strains were isolated from the saliva of children aged 7 and 8 years vaccinated with live parotitis vaccine at the age of 1.5 years. Primers for the genome site coding for the gene F terminal and the SH gene (a total of 509 n. p.) were estimated and synthesized and the site was amplified. Electron-microscopic examination of purified virus and Vero cells infected with it and serological tests showed a similarity of the newly isolated virus with the Anders strain of parotitis virus. The Dragun-1 and Dragun-2 strains of parotitis virus have been deposited in the collection of viruses at the Vektor State Research Center of Virology and Biotechnology in the village of Koltsovo, Novosibirsk district.

Neonatal suppurative parotitis: a study of five cases.

UNLABELLED: Suppurative parotitis is uncommon in newborns. During a 9-year study period, five cases of neonatal suppurative parotitis were detected in 3,624 hospital admissions. The relative risk of developing neonatal suppurative parotitis in admitted infants was 5.52 (0.62-49.35). Staphylococcus aureus was the causative organism most commonly detected in the hospital-acquired cases. Antimicrobial therapy was effective in all cases; surgery was not required. CONCLUSION: Although neonatal suppurative parotitis is now uncommon in the newborn, it cannot be considered a "vanishing disease".

Tuberculous parotitis: report of 3 cases.

Tuberculous parotitis, particularly the diffuse form, is rare. I describe here three patients with diffuse tuberculous parotitis, two of whom presented with unilateral parotid swelling while the third had swellings of both glands. All had discharging sinuses. In two of the patients, the parotitis was associated with active pulmonary tuberculosis. In the patient with bilateral parotitis, the disease seemed to be confined to the glands. The diagnosis of tuberculosis was confirmed by the finding of tubercle bacilli in the lesion or the sputum. They all responded well to standard antituberculous drugs.

Parotitis due to anaerobic bacteria.

Although Staphylococcus aureus remains the pathogen most commonly implicated in acute suppurative parotitis, the pathogenic role of gram-negative facultative anaerobic bacteria and strict anaerobic organisms in this disease is becoming increasingly recognized. This report describes a case of parotitis due to Bacteroides disiens in an elderly woman with Sjögren's syndrome. Literature reports on seven additional cases of suppurative parotitis due to anaerobic bacteria are reviewed. Initial therapy of acute suppurative parotitis should include coverage for S. aureus and, in a very ill patient, coverage of gram-negative facultative organisms with antibiotics such as cloxacillin and an aminoglycoside. A failure to respond clinically to such a regimen or isolation of anaerobic bacteria should lead to the consideration of the addition of clindamycin or penicillin.
