Uptake index and stimulated salivary gland response in 99Tcm-pertechnetate salivary gland scintigraphy in normal subjects.

With a view to improve the diagnosis of salivary gland diseases (in particular, Sjögrén's syndrome) associated with decreased salivary gland function and decreased stimulated salivary gland response, the normal range of radionuclide uptake function and the stimulated salivary gland response were established in 27 subjects without any known salivary gland disease. Following injection of 99Tcm-pertechnetate, sequential images were recorded for 40 min with oral administration of citric acid at 30 min. The total uptake index (TUI) was calculated as the sum of the background corrected count rates over the parotid and submandibular glands at 3 min divided by the injected dose. The TUI, expressed as a percentage of dose, was 0.55 +/- 0.12 (mean +/- S.D.). The stimulated salivary gland response (SSGR) was calculated as the difference between the rate constants (min-1) of monoexponential fits to the time-activity curves over the four salivary glands immediately after and before the administration of citric acid. The lower significance limit (P < 0.05) of the SSGR was a 2.4% decrease per min. The parameters TUI and SSGR can be used as a diagnostic tool in, for example, early Sjögren's syndrome.

Multiple suppurative cystic lesions of the lips and buccal mucosa: a case of suppurative stomatitis glandularis.

Cheilitis glandularis (CG) is a rare inflammatory salivary gland disease that usually affects the lips. Although the etiology of CG is still unknown, it is believed to be a hereditary disease with an autosomal dominant pattern of inheritance. Three clinical presentations of CG are described in the literature: simple, superficial suppurative, and deep suppurative. A case of deep suppurative CG that extended to the buccal mucosa has been previously reported as suppurative stomatitis glandularis (SSG). Here we report a case of SSG in a 64-year-old white female with a history of bilateral renal transplants for adult polycystic kidney disease, who presented with painful swollen lips and bilateral buccal mucosal lesions. The diagnosis and management of the case is discussed. To the best of our knowledge, this is the second report of SSG, a rare condition affecting the minor salivary glands in the oral cavity.

Salivary mucoceles.

The overall incidence of salivary gland disease in dogs and cats is low. Salivary mucocele is the most frequently diagnosed disease of salivary glands. Mucoceles consist of collections of saliva in subcutaneous, sublingual, pharyngeal, or periorbital locations. Definitive therapy of salivary mucoceles consists of excision of the affected salivary gland and mucocele drainage.

[Sialographic and computed tomographic studies in pathology of the major salivary glands].

A retrospective study is reported which took place over 3 years (1986-1989) and included 99 patients (57 men and 33 women, age range 8-90 years) with lesions attributable to salivary gland diseases. Patients were examined using CAT and sialographic tests. From an analysis of the results it is clear that sialography retains its importance as a means of diagnosis in inflammatory diseases, calculosis and autoimmune disorders, whereas CAT should be used as the preferential diagnostic test for neoplastic lesions.

[Sialadenosis of the parotid gland. Ultrastructural, clinical and experimental findings in disturbances of secretion (author's transl)].

Among the secretory disturbances ("Dyschylien") of salivary glands the sialadenosis of the parotid gland is a clinic and a morphologic definited entity. The typical clinical symptom is a bilateral, often recurrent, and painless swelling of the parotid gland. The characteristic pathological findings consist in an acinar cell hypertrophy without any inflammatory signs. According to this definition, sialadenosis has to be separated from those diseases of salivary glands, which are primarily altered by inflammation of the salivary tissue with secondary secretory disturbances. From flinical point of view it is possible to distinguish the following kinds of sialadenosis according to the syntropy with various diseases: Endocrine sialadenosis (in diabetes mellitus, dysfunction of gonads, pituitary gland, thyroid gland etc.); dystrophic-metabolic sialadenosis (malnutrition, avitaminosis, alcohilsm, chronic liver diseases etc.), and neurogenic sialadenosis (dysfunction of the vegetative nervous system, drug damages e.g. antihypertensive agents). The question arises, whether all forms of sialadenosis have a common etiology and a coincidental pathogenic factor. The following studies were carried out with the aim to find further details concerning the etiology and pathogenesis of sialadenosis. The study is based on the following material: a) 126 Biopsies of parotid glands from patients with sialadenosis (Register of salivary gland diseases at the Institute of Pathology, University of Hamburg, supported by Deutsche Forschungsgemeinschaft). This material was collected from 1965 to 1973. b) 80 Biopsies of parotid glands from patients with other diseases (parotitis [4]; acinic cell carcinoma [4]; other parotid and oral tumors [72]; for comparison. c) Experimental studies on the parotid salivary glands of Wistar-rats. The biopsies of the parotid glands were studied histologically, morphometrically, and ultrastructurally. The investigations centered on the ultrastruct of sialadenosis. Before interpreting the ultrastructural findings in view of etiology and pathogenesis of sialadenosis, it was primarily necessary to study the normal ultrastructure of the human parotid gland including the vegetative nervous system. Furthermore it was necessary to elucidate details of a functional morphology of the secretory cycle and to integrade the findings into a concept of general pathology of secretory disturbances. The following results were achieved by our investigations: 1. Normal ultrastructure of human parotid gland: The architecture of the acinar cells is identical with these of other animal species (cytoplasm with a basal standing nucleus, rough endoplasmatic reticulum, Golgi-apparatus, secretory granules etc.). Further identical elements are intercalated and striated ducts, myoepithelial cells, and the vegetative nervous system (postganglionic sympathetic and parasympathetic neurites, however no ganglionic cells in the parotid gland)...

A new device for measuring oral mucosal surface friction--reference values.

Sialometry and dryness measurements performed with a sliding friction instrument were carried out in healthy subjects and patients with oral dryness due to salivary gland diseases. The salivary flow rates were within normal reference values. The mean friction value in the healthy population was 1.73 +/- 0.37 in the lip mucosa and 1.25 +/- 0.31 in the buccal mucosa and did not show any age or sex differences. In the group of patients with salivary gland diseases, none produced measurable amounts of resting saliva but a few of them did produce small amounts of paraffin wax chewing-stimulated saliva. The friction instrument proved to register lubrication produced even by these very small amounts of saliva.

The use of sialodochoplasty in the treatment of benign inflammatory obstructive submandibular gland disease.

One of the most common causes of submandibular gland enlargement is benign inflammatory disease. The usual cause is ductal outflow obstruction due to either a calculus or stenosis allowing stasis and retrograde movement of the saliva into the acinar structures leading to an inflammatory response and gland enlargement. Faced with a submandibular mass, a work-up that will rule out neoplastic causes of submandibular enlargement is instituted. This includes clinical assessment, probing of the gland, radiocontrast sialography, and CT scanning. The treatment should reflect the obstructive nature of the disease. Plastic reconstruction of the duct allows the removal of calculi, shortening of the duct, and enlargement of the outflow opening preventing recurrence and allowing healing of the gland. The procedure is performed intraorally as an outpatient, does not disrupt oral functioning, or subject the patient to the risks of gland removal or loss of that organ's function. Our experience with 27 patients over a 7-year period is presented with a detailed description of the technique and an analysis of the results. The procedure was successful in 22 of the 27 patients.

Salivary gland involvement in systemic diseases.

The salivary glands participate in systemic illnesses because they are secretory structures allied with the gastrointestinal tract. Thus they are involved in systemic inflammatory, allergic, and neoplastic conditions. Perhaps the most common condition is that of mumps in the acute phase. Of the chronic diseases, Mikulicz's disease or Sjögren's syndrome is most frequently noted. In most instances of systemic involvement, the salivary gland enlargement is the rule, with the gland being tense, soft, and enlarged, and with progressive growth over a period of time. Usually all glands are involved. The diagnosis should be suspected from the history and the physical examination, noting that all the glands are equally involved by the enlargement. If there is any question, a biopsy should be performed. In the case of Sjögren's syndrome, the biopsy specimen may be taken either from a major salivary gland or from one of the minor ones, or the nasal mucous membrane or oral cavity. In general, definitive therapy is unsuccessful for the systemic illness involving the salivary glands, and in most instances has to be supportive.

Cytological diagnosis of sialadenosis, sialadenitis, and parotid cysts by fine-needle aspiration biopsy.

This analysis permits the following conclusions: The value of punctate cytology consists in the possibility to verify the clinical diagnosis of a cyst by aspiration of fluid, and to make a preoperative assessment of the necessity of an operation and its type and extent, if proof of a benign or malignant tumor was obtained by microscopic examination. The diagnostic value of punctate cytology can be increased if after aspiration of cyst fluid also solid tissue components from the region of the cyst are included. Patients whose biopsy aspirates did not give evidence for the presence of a tumor should be reexamined 2-4 weeks later. Operative treatment will not be necessary if the follow-up examination reveals that the parotid swelling has subsided. Without this control investigation, recommended by Zajicek [80], morphological aspects always indicate an operation if tumor-negative biopsies cannot be etiologically classified even though clinical data were included in the diagnostic procedure.

[Salivary gland ultrasonography].

Many pathologic conditions of the salivary gland are diagnosed clinically. Until a few years ago, supplementary radiographic methods have only included plain film radiography and sialography. Both methods vary in usefulness, and the indications are controversial. During the last two decades other imaging methods, both radiographic and non-radiographic, have been used, and have provided clinically useful information. Probably the most useful of these is ultrasonography. Because the salivary glands are superficial structures they lend themselves well to ultrasonographic evaluation. Although sialography should still be the method of choice for some conditions, ultrasonography alone will often give the correct diagnosis. The purpose of this article is to describe the role of sonography for imaging pathologic conditions of the salivary glands.
