Investigation of salivary gland disease.

The various techniques available for the investigation of salivary gland disease are described and their clinical applications discussed. Sialography and scintigraphy are most helpful in cases of recurrent glandular swelling, and CT or MRI in the evaluation of tumors.

[Protein composition of human saliva under rest and stimulation and its changes in salivary gland diseases].

In 153 probands the following parameters of normal parotid gland secretion were examined: flow-rate, total protein excretion, lysozyme, amylase, phosphatase, BAEE-esterase, immunglobulin A and trypsin-inhibitor. The results were compared with secretions of parotid glands with tumors (51 patients), sialadenitis (22 patients) and sialadenosis (12 patients). Thereby differential diagnosis in sialotumors was found possible. The mose important parameters are flow-rate, protein and immunglobulin A-concentrations, Moreover it is possible to differentiate in sialadenitis and sialadenosis: lysocym secretion gives besides flow--rate protein and immunglobulin A-concentration a good parameter in differentiating both pathological findings. Discelectrophoretic and immunoelectrophoretic separations supplement the differential diagnosis in sialotumors, sialadenitis and sialadenosis. The results are discussed.

[Salivary gland diseases].

Only about 1% of head and neck tumors are neoplasms of the salivary glands. The majority [80%] of these tumors are benign. Pleomorphic adenomas, the most frequent benign tumors of the salivary glands, can transform into malignancy, especially after a long duration. Treatment of salivary gland tumors consists of complete surgical excision by a surgeon experienced in microsurgery of the facial nerve. Acute suppurative and viral sialadenitis is usually treated by the general practitioner either symptomatically or, if possible, specifically. Chronic sialadenitis, sialadenosis, Sjögren's syndrome, and Frey's syndrome often need long-term follow-up and medical treatment, which is also usually delivered by the general practitioner, after the diagnosis has been established. Trauma to the salivary gland with transsection of the duct or facial nerve needs immediate microsurgical repair by an otolaryngologist. Sialolithiasis is also treated surgically in most cases.

Elevated serum amylase activity in the absence of clinical pancreatic or salivary gland disease: possible role of acute hypoxemia.

Elevated serum amylase activity, in the absence of clinically apparent pancreatic or salivary gland disease, has been observed in many seemingly unrelated conditions. In a search for common etiological factors to account for hyperamylasemia in these conditions, a retrospective analysis was performed. Eighty-four episodes of hyperamylasemia (greater than 300 I.U./l. Phadebas method) occurring in 75 patients over a one-year period ending in June, 1975 were assigned to one of two groups. Group 1 consisted of 56 (67%) episodes of hyperamylasemia with clinical pancreatitis. Group 2 consisted of 28 (33%) episodes of hyperamylasemia in the absence of clinical pancreatitis. Hypoxemia (pO2 less than 75 mm. Hg.) was found in 9/15 patients in Group 2 who had arterial blood gases measured. To assess the possible relationship between acute hypoxemia and amylase activity, a prospective study was initiated. Patients with known causes of pancreatitis or renal failure were eliminated. Hyperamylasemia was found in 3/8 hypoxemic patients. This raises the possibility that acute hypoxemia alone or in combination with other factors may raise serum amylase activity, possibly through ischemic injury to the pancreas or salivary glands or other amylase containing tissues.

Serum anti-SS-B/La and IgA rheumatoid factor are markers of salivary gland disease activity in primary Sjögren's syndrome.

OBJECTIVE: To identify serologic markers of salivary gland disease activity in 43 patients with primary Sjögren's syndrome. METHODS: Comparison of salivary gland biopsies (focus scores) and flow rates with serum concentrations of IgA and IgM rheumatoid factor (RF), total serum IgG, serum anti-SS-B/La antibodies, and the erythrocyte sedimentation rate. RESULTS: Serum anti-SS-B/La antibody levels correlated with focus scores (rs = 0.477, P < 0.0025). Serum IgA-RF concentrations correlated inversely with stimulated parotid gland salivary flow rates (rs = -0.394, P < 0.01). CONCLUSION: Measuring serum levels of anti-SS-B/La and IgA-RF would be useful when monitoring salivary responses in therapeutic trials, especially in patients with minimal salivary function.
