Abstract
PURPOSE To provide a detailed overview of the fundamentals of saliva constituents and production. The review outlines the clinical manifestations as a consequence of salivary gland dysfunction and management strategies for patients with salivary gland dysfunction. Prosthodontic implications of saliva and salivary gland dysfunction are presented. MATERIALS AND METHODS English-language literature relating to saliva constituents, physiologic saliva production, clinical manifestations secondary to salivary gland dysfunction, salivary biomarkers, and management strategies were retrieved via electronic search. Relevant articles were summarized for this manuscript with a view toward providing pragmatic information. RESULTS Saliva is produced by three pairs of major and minor salivary glands. The major salivary glands, namely, the parotid, submandibular, and sublingual glands, contribute approximately 90% of saliva production. Saliva contains serous and mucinous secretions produced by different types of cells within salivary glands. Parasympathetic and sympathetic fibers innervate the major salivary glands, and upon stimulation, the parasympathetic innervation increases serous secretions, while the sympathetic innervation increases protein secretion. Stimulated saliva is mainly derived from the parotid glands which are composed of serous acini, while unstimulated saliva is mainly derived from the submandibular glands which are composed of mixed seromucous acini. As major salivary glands contribute the most to salivary flow, local or systemic factors influencing those glands can disrupt saliva production resulting in clinically significant oral manifestations. CONCLUSION This review provides a fundamental overview of saliva production. In addition, the review highlights the various clinical manifestations secondary to salivary gland dysfunction, explores salivary biomarkers for screening of systemic diseases, discusses management strategies for patients with salivary gland dysfunction, and outlines the prosthodontic implications of saliva and salivary gland dysfunction.

Quantitative Single-Photon Emission Computed Tomography/Computed Tomography for Evaluation of Salivary Gland Dysfunction in Sjögren's Syndrome Patients. Nucl Med Mol Imaging 2018; 52:368-376. [PMID: 30344785 DOI: 10.1007/s13139-018-0547-4] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2018] [Revised: 09/07/2018] [Accepted: 09/11/2018] [Indexed: 10/28/2022] Open
Abstract
Purpose The purpose of the study was to investigate the usefulness of quantitative salivary single-photon emission computed tomography/computed tomography (SPECT/CT) using Tc-99m pertechnetate in Sjögren's syndrome (SS). Methods We retrospectively reviewed quantitative salivary SPECT/CT data from 95 xerostomic patients who were classified as either SS (n = 47, male:female = 0:47, age = 54.60 ± 13.16 y [mean ± SD]) or non-SS (n = 48, male:female = 5:43, age = 54.94 ± 14.04 y) by combination of anti-SSA/Ro antibody, labial salivary gland biopsy, unstimulated whole saliva flow rate, and Schirmer's test. Thyroid cancer patients (n = 43, male:female = 19:24, age = 46.37 ± 12.13 y) before radioactive iodine therapy served as negative controls. Quantitative SPECT/CT was performed pre-stimulatory 20 min and post-stimulatory 40 min after injection of Tc-99m pertechnetate (15 mCi). The %injected dose at 20 min and the %excretion between 20 and 40 min were calculated for parotid and submandibular glands, generating four quantitative parameters: %parotid uptake (%PU), %submandibular uptake (%SU), %parotid excretion (%PE), and %submandibular excretion (%SE). The most useful parameter for SS diagnosis was investigated. Results The uptake parameters (%PU and %SU) were significantly different among the SS, non-SS, and negative controls (p = 0.005 for %PU and p < 0.001 for %SU, respectively), but the excretion parameters (%PE and %SE) were not (p > 0.05 for both). The %PU and %SU were significantly lower in SS than in the negative controls and non-SS (p < 0.05 for all pair-wise comparisons). Additionally, the %SU was significantly lower in non-SS than in the negative controls (p < 0.05). Receiver-operating characteristic analysis revealed that the %SU had the greatest area-under-the curve of 0.720 (95% confidence interval = 0.618-0.807). Using the optimal cut-off value of %SU ≤ 0.07%, SS was identified with a sensitivity of 70.21% and a specificity of 70.83%. Conclusion Reduced submandibular uptake of Tc-99m pertechnetate at 20 min (%SU) was proved useful for the diagnosis of SS. Quantitative salivary gland SPECT/CT holds promise as an objective imaging modality for assessment of salivary dysfunction and may facilitate accurate classification of SS.

Abstract
SummaryThe aim of this study was to compare the diagnostic utility of visual versus semiquantitative analysis of salivary gland scintigraphy in the diagnosis of Sjögren’s syndrome (SS). Patients, methods:
99mTc-pertech- netate salivary gland scintigraphy was performed in 145 patients (133 women, 12 men) with clinically suspicious SS. The images were interpreted with visual and semiquantitative methods and the diagnostic performances for SS were compared using uptake and excretory functional parameters. Results: In total, 76 patients (52.4%) were finally diagnosed with SS. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of visual analysis for the diagnosis of SS were 88.2%, 48.6%, 65.1%, 79.1%, and 69.2%, respectively. Semiquantitative values, the area under the ROC curve for uptake ratio and percentage excretion in the right salivary glands were significantly greater than 0.5 (p < 0.05). However, the percentage excretion in the left salivary glands did not show a statistically significant diagnostic ability for SS. The diagnostic ability of visual assessment was greater than that of the semiquantitative method in terms of evaluating uptake and excretory function in the sub- mandibular glands. Conclusion: Visual analysis of salivary gland scintigraphy showed greater diagnostic utility than semiquantitative assessment in the diagnosis of SS, especially in the submandibular glands.

Abstract
Background The most advocated clinical method for diagnosing salivary dysfunction is to quantitate unstimulated and stimulated whole saliva (sialometry). Since there is an expected and wide variation in salivary flow rates among individuals, the assessment of dysfunction can be difficult. The aim of this systematic review is to evaluate the quality of the evidence for the efficacy of diagnostic methods used to identify oral dryness. Methods A literature search, with specific indexing terms and a hand search, was conducted for publications that described a method to diagnose oral dryness. The electronic databases of PubMed, Cochrane Library, and Web of Science were used as data sources. Four reviewers selected publications on the basis of predetermined inclusion and exclusion criteria. Data were extracted from the selected publications using a protocol. Original studies were interpreted with the aid of Quality Assessment of Diagnostic Accuracy Studies (QUADAS) tool. Results The database searches resulted in 224 titles and abstracts. Of these abstracts, 80 publications were judged to meet the inclusion criteria and read in full. A total of 18 original studies were judged relevant and interpreted for this review. In all studies, the results of the test method were compared to those of a reference method. Based on the interpretation (with the aid of the QUADAS tool) it can be reported that the patient selection criteria were not clearly described and the test or reference methods were not described in sufficient detail for it to be reproduced. None of the included studies reported information on uninterpretable/intermediate results nor data on observer or instrument variation. Seven of the studies presented their results as a percentage of correct diagnoses. Conclusions The evidence for the efficacy of clinical methods to assess oral dryness is sparse and it can be stated that improved standards for the reporting of diagnostic accuracy are needed in order to assure the methodological quality of studies. There is need for effective diagnostic criteria and functional tests in order to detect those individuals with oral dryness who may require oral treatment, such as alleviation of discomfort and/or prevention of diseases.

Abstract
PURPOSE Salivary gland scintigraphy (SGS) provides an objective means of diagnosing salivary gland dysfunction in Sjögren's syndrome (SS) patients and in thyroid cancer patients after radioactive iodine (RAI) therapy. In the present study, SGS was performed in SS patients and in thyroid cancer patients post-RAI, and scintigraphic parameters were compared. METHODS Twenty-eight SS patients (males:females = 1:27, age 53.3 ± 11.9 years), 28 controls (males:females = 3:25, age 54.1 ± 10.1 years), and 92 thyroid cancer patients (males:females = 28:64, age 46.2 ± 12.9) who had undergone a session of high-dose RAI therapy (mean dose, 5.2 ± 1.5 GBq) were included. SGS was performed using Tc-99m pertechnetate (925 MBq). Scintigraphic parameters (parotid uptake ratio PU, submandibular uptake ratio SU, percentage parotid excretion %PE, and percentage submandibular excretion %SE) were measured and compared for SS, thyroid cancer post-RAI, and control patients. RESULTS PU, SU, %SE, and %PE were all significantly lower in SS than in post-RAI thyroid cancer or control patients (p < 0.05), whereas only %PE was significantly lower in post-RAI thyroid cancer patients than in controls (p < 0.05). SU and %SE were found to be correlated with the unstimulated whole salivary flow rate. CONCLUSION Scintigraphic parameters derived from SGS can play a crucial role in the detection of salivary gland dysfunction in SS patients and in post-RAI thyroid cancer patients.

Abstract
Salivary gland scintigraphy (SGS) is a non invasive method of salivary gland function assessment. This technique is easy to perform, reproducible and well tolerated by patients. Additionally, an abnormal salivary gland scintigraphy result is accepted by the American-European consensus group as a criterion for the diagnosis of Sjögren's syndrome. Scintigraphic evaluation of salivary gland function also plays an important role in therapeutic decision and patient follow-up. Schall's categorical classification is usually considered the standard method for salivary scintigraphy interpretation, though subjective and with limited capacity to discriminate borderline results. In order to improve the diagnostic accuracy of SGS, there has been an increasing interest in the quantification of glandular function. However, the debate on the most reliable and suitable parameters for the diagnosis of SS persists.

Abstract
BACKGROUND/AIM Beside many actual groups of classification criteria, uniform classification criteria for Sjögren's syndrome (SS) are still missing. The ophtalmic component of SS is well defined. Criteria for classifying its oral component remain controversial. The fifth item of the European Union and the United States of America (EU-US) revised diagnostic classification criteria in 2002, is an objective evidence of xerostomia, diagnosed by one of the tests: unstimulated whole sialometry (UWS), parotid sialography, and dynamic salivary gland scintigraphy (DSGS). The aim of this study was to evaluate senstitivity, specificity, positive and negative predictive value and accuracy of DSGS with ascorbic acid stimulation in detecting xerostomia in SS patients and to compare DSGS findings with UWS values. METHODS Tests DSGS and UWS were done in 20 patients with SS and in 10 of the control subjects. The findings of DSGS were graded from 1 to 4 scintigraphie (SCT) grade 1--normal finding; SCT grade 2--moderate function damage; SCT grade 3--serious function damage, SCT grade 4--very serious function damage. UWS measured 1.5 hour after the breakfast lasted 15 minutes. UWS bellow 2.5 ml/15min min. considered pathological. RESULTS All SS patients had pathological SCT findings. Comparing SCT grade between the patients and the control group, high statistical significance was found (p < 0.001). The estimated sensitivity of DSGS was 100%, specificity 80%, positive predictive value 91%, negative predictive value 100% and accuracy 93%. The calculated sensitivity of UWS was 75%. Salivary function damage detected by scintigraphy was in positive correlation with UWS findings. CONCLUSION DSGS is a diagnostic test with high sensitivity, specificity, accuracy and positive and negative predictive values in detecting salivary function damage in SS patients. DSGS and UWS are very sensitive diagnostic tests for objective evidence of xerostomia, and have to be ones of the earliest investigations which shoud be performed in subjects suspected of SS. Test DSGS is more sensitive, and seems to better reflect symptoms of dry mouth than UWS.

Abstract
Abnormal findings on salivary gland scintigraphy (SGS) are part of the classification criteria for Sjøgren's syndrome (SS), but SGS is operator dependent and poorly standardised. We studied the use of quantitative data on the uptake, concentration and excretion of the four major salivary glands in the evaluation of sicca patients. During an initial clinical evaluation for sicca symptoms (mean duration, 51 months), 24 subjects were classified as either SS (n = 8) or isolated sicca (IS; n = 16). SGS was then performed after i.v. injection of 200 MBq pertecnetat. Digitalised quantitative data on time-to-peak uptake (Tmax), peak tracer distribution (C%) and stimulated excretion (E%) were calculated from time-activity curves and compared between groups and controls (n = 8) and correlated to clinical data. Statistical analysis was performed with non-parametric tests. SS patients had longer Tmax in both parotic glands (18.1 min; p < 0.01)) and both submandibular glands (mean 13.7 min, p < 0.05); whereas Tmax in IS patients was similar as in controls in both parotic (10.4 min; p > 0.2) and submandibular glands (9.4 min; p > 0.4). C% was significantly lower in the parotic glands of both the SS and the IS group compared to the controls (p < 0.01). E% was significantly reduced in SS patients (16.3% for parotic and 17.4% for submandibular glands; p < 0.01); whereas in the IS patients, excretion (32, 2% for parotic and 26, 9% for submandibular glands) was similar from all glands as in the control groups (35, 2% for parotic and 27, 8% for submandibular glands). No correlation was found between these SGS results and age, focus score, erythrocyte sedimentation rate, serum creatinin or immunoglobulin levels. No IS patient progressed to full-blown pSS during the 4 years of follow-up. Quantitative SGS data are useful and objective tools to distinguish patients with SS.

Abstract
OBJECTIVE Total body irradiation (TBI) and cyclophosphamide (CY) during allogeneic stem cell transplantation (ASCT) cause salivary gland dysfunction in children. The aim of this investigation was to study the scintigraphic functional changes over time of the parotid and submandibular glands in children and young adults one year after treatment with CY and TBI at ASCT. METHODS Salivary gland scintigraphy (SGS) was performed before ASCT, and 3-6 months and 12 months after ASCT. The three male patients who fulfilled the scintigraphic study had a mean age (+/- SD) of 17.3 +/- 9.8 years at ASCT. RESULTS The parotid secretion capacity (SPar) was 83.5 +/- 3.2% before ASCT and 48.5 +/- 25.8% during the next 3-6 months (P < 0.05). The SPar did not increase (48.1 +/- 12.4%) during the rest of the first year after ASCT. The submandibular emptying capacity (SSub) was 91.3 +/- 12.9% before ASCT and 35.4 +/- 2.3% after 3-6 months (P < 0.05). The SSub was 87.9 +/- 17.9% one year after ASCT. CONCLUSIONS The parotid glands were more sensitive to irradiation since they did not recover lost capacity to secrete saliva, while the submandibular glands recovered the secretion capacity at the one-year follow-up.

Abstract
AIM To assess the effect of gender and age on [99mTc]pertechnetate salivary gland scintigraphy (SGS) in healthy subjects. METHODS The study population consisted of 93 normal subjects (46 women, 47 men; age range 20-59 years). The subjects were categorized into eight (four female and four male) subgroups according to age decades. Dynamic SGS was performed after intravenous injection of 370 MBq [99mTc]pertechnetate. Anterior salivary gland images were acquired for 30 min. On the basis of the time-activity curves, three functional parameters were calculated for the parotid and submandibular salivary glands: (1) the first minute uptake ratio, (2) the maximum uptake ratio, and (3) the maximum secretion percentage. RESULTS For women, all parotid and submandibular functional parameters had a peak in the fourth decade group. The comparison of four age groups in the female subjects showed significant differences, except for the third versus the fifth decades, at least for one parameter. The number of significant differences was highest in the comparison between the second versus the fourth decades. Among men, the highest values for all parotid and submandibular parameters were in the second decade, except for the first minute uptake ratio in the submandibular gland. The number of parameters that were significantly different among the four age groups in men was lower than in women. The first minute uptake ratio of the submandibular gland had the most significant differences among the groups of male subjects. CONCLUSION Age and gender differences have a significant effect on salivary gland functions which is more apparent in women than in men.

Abstract
AIM The purpose of this case-control study was to determine whether semi-quantitative indices derived from salivary time-activity curves (TACs) are useful in the diagnosis and management of xerostomia. METHODS Twenty-six healthy volunteers and 83 consecutive patients with xerostomia, including a subset of 40 patients with Sjogren's syndrome, underwent sequential salivary scintigraphy (SSS). Semi-quantitative analysis of the TACs was performed, deriving six different indices, previously cited in the literature, for each patient. These reflected trapping and uptake, stimulated excretion, or stimulated and unstimulated oral radioactivity. The indices were the percentage uptake, uptake ratios, maximum accumulation, pre-stimulatory oral radioactivity index, post-stimulatory oral radioactivity index and ejection fraction. RESULTS Reduced parotid activity relative to submandibular activity, expressed as the P : S ratio, was able to distinguish abnormal from normal salivary function, and a parotid ejection fraction of greater than 50% also indicated normal parotid function. The other parameters showed no statistically significant difference between controls and patients. Individual variation in all indices served to widen the reference limits obtained from controls to the extent that they overlapped with those from the xerostomic population. CONCLUSIONS This finding, together with previous work indicating that uptake parameters are only sensitive to differences exceeding 25% of the gland mass, the possibility that xerostomia may result from qualitative as well as quantitative changes in saliva and the probability that immune factors decrease neurosecretory circuits without affecting acinar mass, suggest that those indices derived from salivary TACs that directly reflect trapping and uptake are not useful in the detection of salivary gland disease.

Abstract
OBJECTIVE To characterise the psychological profiles of Sjögren's syndrome (SS) and patients with sicca symptoms but without SS; to find predictors for salivary gland function; to evaluate salivary scintigraphy as a method to differentiate between SS and patients with sicca symptoms but without SS. PATIENTS AND METHODS Psychological tests (Medical Outcomes Study Short Form General Health Survey (SF-36), Jenkins Activity Survey, Toronto Alexithymia Scale, and Maastricht Questionnaire for vital exhaustion) were performed and assessment of the function of the salivary glands made in 26 patients with primary SS, 8 with secondary SS, and 9 with sicca symptoms but without SS. Data were analysed with BMDP new system version 1.0 statistical program. RESULTS Psychological profiles were similar in all groups. Hb, RF, ANA, and SSA differentiated between the groups. Results of salivary scintigraphy were predicted to 51% by ANA, SSA, SSB, IgG, IgA, diagnosis, vitality, and role limitations due to emotional problems. No predictors were found for the resting salivary flow. Salivary scintigraphy was pathological in 21/26 (81%) and in 8/8 (100%) patients with secondary SS, but only in 2/9 (22%) patients with sicca symptoms without SS (p=0.002) (sensitivity 85.3%, specificity 77.8%). CONCLUSIONS Patients with sicca symptoms but without SS have sickness behaviour similar to that of patients with SS. The results of salivary scintigraphy can be predicted by diagnosis and autoimmune findings; psychological characteristics added 20% to this predictive value. Distinction between SS and patients with sicca symptoms but without SS is difficult, but in addition to autoantibodies, salivary scintigraphy can be used for this purpose.

Abstract
We evaluated the role of quantitative indices derived from dynamic 99mTc-pertechnetate salivary scintigraphy in the differentiation between a group of patients with Sjögren's syndrome (SS), a group of patients without xerostomia, but with underlying autoimmune disorders, and a group of controls. Seventeen patients with SS (group A), 18 patients with autoimmune disorders (group B) and 15 controls (group C) underwent dynamic salivary gland scintigraphy. Functional indices for the parotid and submandibular glands were calculated and comparisons were made between the groups. There were no significant differences between the three groups in terms of the maximum accumulation (MA), maximum secretion (MS) and pre-stimulatory oral index (PRI). The uptake ratios (URs) for both the right and left parotid glands and the left submandibular gland in group A were significantly lower than those in group C, but no different from those in group B. The URs for the parotid glands in group B were significantly less than those in group C. The percentage uptake by the right parotid gland at 4 min (U4) was significantly lower in group A than in groups B or C, and lower than the percentage uptake by the left parotid gland at 4 min in group A. The rest of the U4 values and all of the uptakes at 14 min (U14) were not significantly different between the three groups. The time taken for the right parotid gland to reach peak activity (Tmax) was significantly less in group A than in the other groups, but other glands showed no significant differences. It can be concluded that MA, MS and PRI cannot be used to differentiate between the three groups. The URs in groups A and B were no different, but were significantly lower than those in group C. However, the extensive overlap between xerostomic patients and normal controls for all the quantitative indices calculated imposes a severe limitation on their discriminatory power.

Abstract
Sjögren's syndrome is a chronic autoimmune and rheumatic disorder with prominent sicca complaints from the mucous membranes because of lack of proper exocrine secretions. There is no straightforward and simple diagnostic test for Sjögren's syndrome, although several classification criteria have been designed including several oral diagnostic tests. A new set of classification criteria in a joint effort by research groups in Europe and USA has recently been presented. A large number of autoantibodies have been reported in Sjögren's syndrome where, in some cases, the antibodies are correlated with the extent and severity of disease. The finding of serum autoantibodies directed against the muscarinic M3 receptor is an important advance in understanding the pathogenesis of not only the impaired glandular function but also associated features of autonomic dysfunction in some patients. The treatment of primary Sjögren's syndrome is still mainly symptomatic.

Abstract
It has been speculated that impaired salivary flow is common in patients with end-stage renal disease (ESRD) requiring hemodialysis (HD). The aim of this study is to investigate the relation between oral manifestations and salivary function in patients with ESRD undergoing HD. Salivary function was measured by quantitative salivary scintigraphy in 60 patients with ESRD undergoing HD, as well as in 36 age- and sex-matched healthy controls for comparison. The 60 patients with ESRD undergoing HD were separated into two subgroups: group 1, 30 patients with oral manifestations, and group 2, 30 patients without oral manifestations. After an intravenous injection of 5 mCi of technetium 99m pertechnetate, sequential images at 1 minute per frame were acquired for 30 minutes. The 1- and 15-minute uptake ratios were calculated as the tracer uptakes in the four major salivary glands over the background regions of interest. Saliva excretion was stimulated by one 200-mg tablet of ascorbic acid administered orally 15 minutes post-tracer injection, then the maximal excretion ratios of the four major salivary glands were calculated. Our results show significantly poorer salivary function in patients with ESRD with oral manifestations compared with patients with ESRD without oral manifestations and healthy controls by means of objective and quantitative salivary scintigraphy.

Abstract
Total body irradiation (TBI) at bone marrow transplantation (BMT) is shown to cause salivary gland dysfunction in children. The aim of the investigation was to study the function of major salivary glands in long-term surviving children following treatment with TBI, using salivary gland scintigraphy (SGS). Thirteen patients (seven male, six female), who had received TBI before the age of 13 years and survived more than 4 years, participated in the study. A reference group of 10 patients (nine male, one female) was examined shortly before they were to undergo BMT. The mean age was 14.1 +/- 4.1 years in the TBI-treated group and 12.8 +/- 5.9 years in the reference group. Unstimulated and stimulated whole salivary secretion rates were measured for 15 and 5 min, respectively, before SGS was performed. The percentage of stimulated secretion was 44.7 +/- 18.1% in the TBI-treated group compared to 58.4 +/- 13.0% in the reference group (P = 0.0438). Slower reaccumulation after excretion was found in the TBI-treated patients compared to the reference group (P = 0. 0300). The function of the major salivary glands in long-term survivors treated with TBI at BMT before the age of 13 years was found to be diminished, as shown by the reduced trapping rate and reduced emptying capacity, compared to prior to BMT.

Abstract
OBJECTIVE To evaluate salivary gland function, saliva composition and oral findings in patients with primary Sjögren's syndrome (pSS) subdivided into patients with and without focus score > or = 1 (FS) and/or antibodies to SSA/SSB (AB) as well as in healthy controls. SUBJECTS AND METHODS Unstimulated (UWS) and chewing stimulated (SWS) whole saliva, and stimulated parotid saliva (SPS) were collected in 16 patients fulfilling the European classification criteria for pSS subdivided into those with FS and/or AB (n = 8) and those without FS and AB (n = 8), and in age-matched (n = 14) and young healthy controls (n = 13). UWS and SWS were analysed for Na+ and K+. SPS was analysed for Na+, K+, statherin, and proline-rich proteins (PRPs). Sicca symptoms, DMFT/DMFS, plaque (PI) and gingival (GI) scores, periodontal pocket depth (PPD), and mucosal status were recorded. RESULTS The young healthy controls had lower UWS as compared to the aged controls (P = 0.03). However, the aged controls had higher DMFT/DMFS (P < 0.001) and PI, GI and PPD (P < 0.01). Patients with FS and/or AB generally had lower saliva secretory rates than patients without FS and/or AB (P = 0.01 for UWS and SPS) and age-matched healthy controls (P = 0.001). There was no significant difference in the content of Na+ and K+, statherin and PRPs between groups. Patients with FS and/or AB had the highest frequency of oral mucosal changes and higher DMFT/DMFS than patients without FS and/or AB and healthy controls (P < 0.01). However, PI, GI, and PPD did not differ significantly. CONCLUSION Patients with FS and/or AB had lower salivary secretory rates, higher DMFT/DMFS, and more oral mucosal changes than patients without FS and/or AB. Additionally, data suggest that salivary gland function in healthy individuals do not decrease with age.

Abstract
PURPOSE Three decades of work to enhance the diagnostic accuracy of salivary scintigraphy have generated various plausible decision criteria. This study evaluates four commonly cited numeric indices in studies of xerostomic populations and how accurately they identify Sjögren's syndrome, chronic sialadenitis, radiation sialadenitis, and drug effects and distinguish each from the other. METHODS Stimulated dynamic salivary scintigraphy was performed on 295 xerostomic patients and on 31 controls. The nonparametric area under the receiver operating characteristic curves expressed the diagnostic accuracy of the following scintigraphic indices: the parotid:submandibular ratio of unstimulated glandular activity, the peak:baseline uptake ratio, its time of occurrence, and the stimulated excretion fraction. RESULTS The stimulated excretion fraction distinguished Sjögren's syndrome and radiation sialadenitis from healthy states with respective accuracies of 0.78 and 0.90. The maximum diagnostic payoff in Sjögren's syndrome occurred at a cutoff of 73%, yielding a 73% rate of test sensitivity and a 73% rate of specificity. The other three indices were not useful. Even the stimulated excretion fraction performed indifferently or poorly in most other diagnostic tasks. CONCLUSIONS In the scintigraphic examination of xerostomic and healthy populations, an acceptable diagnostic utility of the stimulated excretion fraction was evident only in Sjögren's syndrome and radiation sialadenitis. When presented with differential diagnostic alternatives not involving radiation sialadenitis, none of the four numeric indices performed acceptably.

Abstract
Autonomic nervous function was evaluated by deep breathing [expiration/inspiration (E/I) ratio] and tilt table tests [acceleration (AI) and brake indices (BI)] in 19 patients with primary Sjögren's syndrome (pSS) and in 56 age matched controls. The E/I-ratio and systolic blood pressure (at rest, 1, and 8 min after tilt) were found to be significantly reduced (p < 0.001, p < 0.05, p < 0.01, p < 0.01 respectively) in patients with pSS whereas neither AI, BI nor diastolic blood pressure did differ significantly between patients and controls (NS). The van Bijsterveld's score correlated negatively with the AI (r = -0.77, p< 0.001) as well as the BI (r = -0.60, p < 0.01). No correlations were found between the 3 autonomic nerve function parameters (E/I-ratio, AI, BI) and unstimulated whole sialometry or salivary gland scintigraphy. We conclude that autonomic disturbances, mainly affecting the parasympathetic nerves are associated with pSS.

Abstract
An 18-year old girl suddenly developed left-sided abdominal pain with otherwise normal clinical and urine examination. Ultrasound and computed tomography demonstrated a left renomegaly with uniformly normal structure without hydronephrosis, abnormal renal venous flow or ruptured extrauterine pregnancy. Renal biopsy showed lymphocytic interstitial nephritis, compatible with exocrine gland focus score abnormalities, consistent with those found in patients with Sjögren's syndrome. The renomegaly started to diminish after 10 days and the kidney reached normal size after 2 months. All objective tests for keratoconjunctivitis sicca and xerostomia were abnormal, although daily persistent dry eyes and dry mouth symptoms were absent. Serological tests showed high levels of anti-nuclear antibodies, anti-SS-A and anti-SS-B antibodies. Thus the patient fulfils the classification criteria for primary Sjögren's syndrome. The suddenly developed unilateral renomegaly may be an early clinical manifestation of this disease.
