Factors Associated with Hyposalivation in Brazilian Adults

ABSTRACT Objective: To determine the occurrence of hyposalivation in Brazilian adults and its association with individual determinants, such as the use of medications, systemic conditions, smoking, and alcohol consumption. Material and Methods: A cross-sectional study with 402 adults was developed. Information was collected on sociodemographic and general health characteristics, and sialometry was performed with stimulated salivary flow. It indicated low salivary flow when ≤ 0.7 mL/min. Bivariate and multivariate analyses were conducted using a decision tree (p<0.05). Results: The sample was comprised predominantly of women (68.2%) aged ≤ 29 years (25.4%). Most participants did not use medication (56.7%). Among systemic diseases, the most cited was hypertension (25.1%). More than a third of the participants presented hyposalivation (40.3%), being associated with the following variables: age between 50 to 59 years (p=0.011), female sex (p<0.001), menopause (p=0.001), use of alcohol (p=0.033), systemic disease (p=0.002) and medication use (p<0.001). In multivariate analysis, in addition to sex (p<0.001) and hypertension (p=0.005), an association was also found between hyposalivation and diabetes (p=0.014). Conclusion: Factors associated with hyposalivation in adults were sex and the presence of hypertension or diabetes.

The clinical effects on the salivation of children with cerebral palsy of oral-facial muscle training based on action observation and a virtual environment / 中华物理医学与康复杂志

Objective:To observe the effect of oral-facial muscle training applying virtual reality technology (VR) and of action observation therapy on the salivation of children with cerebral palsy (CP).Methods:Sixty CP children with uncontrolled salivation were randomly divided into a control group and an observation group, each of 30. In addition to conventional rehabilitation treatment, the control group received routine tongue muscle training, buccal lip muscle training, ice stimulation, and Masako swallowing training. The observation group received oral-facial muscle training based on action observation therapy in a virtual environment. Both groups were trained 30min per day, 5 times a week for 3 weeks. Before and after the treatment, drooling (DDSS) and swallowing function scores were evaluated. Integrated surface electromyography (iEMG) of the buccinator and orbicularis oris muscles was also performed.Results:After treatment, a significant decrease was observed in the average DDSS and the swallowing function scores of both the control and observation groups, along with a significant increase in the average root mean square values of the buccinator and orbicularis oris iEMGs of both groups. However, the average DDSS score of the observation group was significantly lower than that of the control group, while the average iEMG readings were significantly better.Conclusion:VR-based action observation oral-facial muscle training is a more effective supplement to conventional rehabilitation treatment than conventional oral-facial muscle training in improving the salivation of children with CP.

Sialendoscopy for Improvement of Salivary Flow in Patients with Sjögren Syndrome - Comparative Analysis of Intraglandular Washing Solutions

Abstract Introduction Among the potential diseases that present altered salivary flow and activity is Sjögren syndrome. Sialendoscopy seems to be an important therapeutic option. Objective To compare the results obtained with sialendoscopy for improving salivary flow measured by scintigraphy in patients with primary Sjögren syndrome to those obtained with other intraglandular washing solutions. Methods Patients from our institution's rheumatology clinic diagnosed with primary Sjögren syndrome underwent parotid scintigraphy prior to the sialendoscopy procedure. During the sialendoscopy procedure, one of the parotid glands was randomized to receive a wash with saline while the other was washed with a corticosteroid solution. After 1 month, a new scintigraphy examination of the parotid glands was performed to observe the salivary flow for comparison. Results A total of 13 female patients with mean age of 53.38 years (range, 27-76 years) were included in this study. After sialendoscopy, 10 patients (76.92 %) were observed to have improvement in salivary excretion with radiopharmaceutical during scintigraphy. When analyzing each gland that was treated separately (26 glands), after sialendoscopy, improvement was observed in 18 glands (69.23 %), 8 treated with dexamethasone and 10 with saline solution in the wash. There was no improvement in 8 glands (30.77 %). Conclusion This study demonstrates that sialendoscopy is as an important tool to improve salivary flow measured by scintigraphy in patients with primary Sjogren syndrome, increasing salivary excretion through dilation and consequent unblocking of the ducts. These data suggest that there is no statistically significant difference between intraductal washing solutions using saline or dexamethasone solution.

The characteristics of gastrointestinal symptoms in patients of Parkinson′s disease / 中华神经科杂志

Objective:To investigate the characteristics of gastrointestinal (GI) symptom spectrum in patients with Parkinson′s disease (PD), and to help the early identification of gastrointestinal symptoms and management of PD.Methods:One hundred PD patients in the Department of Neurology, Peking Union Medical College Hospital from January 2017 to August 2017 were enrolled in this study. They were assessed by face-to-face GI dysfunction questionnaire, including eight common symptoms involved in oropharynx, upper and lower digestive tract. The Spearman correlation analysis was performed.Results:The age of PD patients was (61.9±10.5) years, the ratio of male to female was 53∶47 and the disease duration was 4.0 (2.0, 6.0) years. There were 42 cases of Hoehn-Yahr (H-Y) stage 1, 30 cases of H-Y stage 2 and 28 cases of H-Y stage 3 and above (24 cases of H-Y stage 3, three cases of H-Y stage 4 and one case of H-Y stage 5). Totally 58% (58/100) of PD patients had one or more GI symptoms. Constipation (42%, 42/100), dysdefecation (38%, 38/100) and salivation (28%, 28/100) were the top three of most common GI symptoms. Lower GI symptoms were the most common (57%, 57/100), followed by oropharyngeal symptoms (33%, 33/100), and upper GI symptoms (27%, 27/100). GI symptoms could appear in H-Y stage 1 patients, 26.1% (11/42) of which had 1-2 kinds of GI symptoms and over 20% of which had more than three kinds of GI symptoms. A total of 39.3% (11/28) of PD patients with H-Y stage ≥3 had more than three kinds of GI symptoms. The Gastroparesis Cardinal Symptom Index (GCSI) score in patients with upper GI symptoms was 3.0 (2.0,6.5). The constipation symptom score in patients with constipation and dysdefecation was 19.0 (12.0,27.3). As for the clinical type of constipation, 66.7% (38/57) of them were mixed, 21.0% (12/57) were slow transit and 12.3% (7/57) were dysdefecation. In 38.6% (22/57) of the constipated patients, constipation symptoms occurred earlier than PD motor symptoms. Correlation analysis showed that H-Y stage was positively correlated with the course of PD, the number of GI symptoms, salivation, constipation, dysdefecation and constipation symptom scores.Conclusions:Constipation, dysdefecation and salivation were the most common GI symptoms in PD patients. PD patients had at least one GI symptom in the early stage (H-Y stage 1). Lower GI symptoms were more common than oropharyngeal symptoms and upper GI symptoms. With the development of PD, the number of GI symptoms, salivation, constipation and dysdefecation were aggravated, which were important for early symptomatic identification and disease management.

Quantitative Analysis of Parotid Gland Secretion Function in Sjögren's Syndrome Patients with Dynamic Magnetic Resonance Sialography

OBJECTIVE: To evaluate the secretory function of parotid glands by dynamic magnetic resonance (MR) sialography and determine the clinical performance of this technique in diagnosing and evaluating Sjögren's syndrome (SS) patients. MATERIALS AND METHODS: This study enrolled 29 healthy volunteers (25 women and 4 men; mean age, 34.8 ± 6.3 years; age range, 26–47 years) and 25 primary SS (pSS) patients (23 women and 2 men; mean age, 37.7 ± 7.9 years; age range, 25–50 years) with decreased secretory function. The volume of the parotid gland ducts was precisely measured for both groups at single pre- and 6 post-gustatory-stimulated phases. Time-dependent volume change ratio curves were generated, four parameters were derived from the curves: the slope of the increase in the first post-stimulation phase (slope(1st)), the peak value, the time-to-peak, the total saliva secretion post-stimulation. All values were used to quantitatively evaluate the secretory function of the parotid gland. The repeated measurement analysis, Mann-Whitney U test and receiver operating characteristic curve were applied. RESULTS: Time-dependent volume change ratio curves demonstrated that there is a statistically significant difference between the two groups (F = 8.750; p = 0.005). A quickly increasing curve was shown in the volunteer group, whereas a slowly increasing curve was shown in the pSS patient group. The slope(1st), peak value and total saliva secretion post-stimulation of the patient group were significantly lower than those of the volunteer group (p = 0.005, p = 0.003, and p = 0.002, respectively). The time-to-peak between the two groups was not significantly different (p = 0.383). The slope(1st) can be used as a discriminator to diagnose SS patients (p = 0.015; odds ratio = 4.234; area under the curve = 0.726). CONCLUSION: Dynamic MR sialography is proven to be an effective method in evaluating salivary gland function and has a great potential in diagnosing and evaluating pSS patients.

Study on the Changes in Distributions and Expressions of Aquaporin5 (AQP5) in Salivary Glands of Mice After Alcohol Ingestion

Alcohol intake is known to affect various organs in the human body, causing reduction of salivation in the oral cavity. Hypo-salivation effect of alcohol is a common feature, but the mechanism in salivary glands is still poorly studied. Therefore, in this study, the changes in salivary secretion and water channel protein (aquaporin5, AQP5) in salivary glands of mice were investigated after ethanol administration. Animals were divided in to 4 groups with the control, 4 g/kg ethanol, 8 g/kg ethanol and 16 g/kg ethanol administration groups. One hour after ethanol administration, saliva was collected from the oral cavity, and the animals were killed and parotid and submandibular glands were extracted to analyze the histopathology, AQP5 immunihistochemistry and AQP5 protein level. According to the results, the salivation rate decreased irrespective of the ethanol dose in mice, and viscosities increased with increase in ethanol dose. However, there were no pathological changes in parotid and submandibular glands due to ethanol administration. Expression of AQP5 in parotid and submandibular glands decreased with increase ethanol administration These results indicate that the reduction of salivary secretion due to acute alcohol intake is closely related to decrease of the water channel protein such as AQP5 in parotid glands and submandibular glands, rather than the damage of salivary glands.

Introduction: A foreign body (FB) in the upper aerodigestive tract is a fairly common encounter.Fish bones are the commonest FB seen in adults. The commonest presentation is odynophagia.Usually, the patient will point at the level of FB on the neck to indicate the location.Methods: Clinical report.Results: This case report describes a large FB in an adult with underlying infantile cerebral palsy.Besides dysphagia, it was associated with drooling of saliva and pain in the throat region.Conclusion: FB ingestion with complete obstruction of the oesophagus is an emergency. It maycause total dysphagia as the passage of food is completely blocked.

Impact of inhalation therapy on the incidence of carious lesions in patients with asthma and COPD

Abstract Objective: The aim of this study was to investigate the incidence of carious lesions, the amount of salivary flow rate and pH value in patients with asthma and chronic obstructive pulmonary diseases (COPD), using inhalation therapy. The obtained results were compared with the results of adult healthy subjects, forming a control group. Material and Methods: The study included 80 participants aging between 18 and 65 years. The experimental group (EG) was comprised of 40 participants, previously diagnosed with asthma or COPD undergoing inhalation therapy for more than five years. The control group (CG), comprised of 40 participants, mirrored the same age and gender status of the EG. Dental status was determined by decayed, missing, and filled teeth (DMFT index). Quantity and pH value of saliva were determined in the laboratory. Results: In the EG, the mean value of the salivary flow rate and pH value were statistically significantly lower than in the CG (p<0.001). Patients in the EG had a higher value of DMFT index when compared with the CG, although the difference was not statistically significant (p=0.199). Mean number of decayed teeth, as well as missing teeth, in the EG was statistically significantly higher than in the CG (p<0.001). Mean number of filled teeth in the EG was statistically significantly lower than in the CG (p<0.001). Conclusion: It was found that patients undergoing inhalation therapy face increasing risk of dental caries due to the lower salivary flow rate and pH value along with the inhalation therapy. They should receive intensive preventive care, including oral hygiene instruction and dietary advice.

Calcium Signaling in Salivary Secretion

Calcium has versatile roles in diverse physiological functions. Among these functions, intracellular Ca²⁺ plays a key role during the secretion of salivary glands. In this review, we introduce the diverse cellular components involved in the saliva secretion and related dynamic intracellular Ca²⁺ signals. Calcium acts as a critical second messenger for channel activation, protein translocation, and volume regulation, which are essential events for achieving the salivary secretion. In the secretory process, Ca²⁺ activates K⁺ and Cl⁻ channels to transport water and electrolyte constituting whole saliva. We also focus on the Ca²⁺ signals from intracellular stores with discussion about detailed molecular mechanism underlying the generation of characteristic Ca²⁺ patterns. In particular, inositol triphosphate signal is a main trigger for inducing Ca²⁺ signals required for the salivary gland functions. The biphasic response of inositol triphosphate receptor and Ca²⁺ pumps generate a self-limiting pattern of Ca²⁺ efflux, resulting in Ca²⁺ oscillations. The regenerative Ca²⁺ oscillations have been detected in salivary gland cells, but the exact mechanism and function of the signals need to be elucidated. In future, we expect that further investigations will be performed toward better understanding of the spatiotemporal role of Ca²⁺ signals in regulating salivary secretion.

Effect of Acupuncture Combined with Low Frequency Electrical Stimulation on Cerebral Palsy Salivation / 中国康复理论与实践

Objective To explore the effect of oral sensorimotor therapy (OSMT), acupuncture, and low frequency electrical stimulation on salivation in patients with cerebral palsy. Methods From September, 2014 to October, 2015, 80 cerebral palsy patients with salivation were recruited. They were randomly divided into four treatment groups:group A was treated with OSMT, group B was treated with acupunc-ture, group C was treated with frequency electrical stimulation, and group D was treated with acupuncture and low frequency electrical stim-ulation, for eight weeks. Meanwhile, 20 cerebral palsy patients with salivation from outpatients were chosen as control group. Results There was no improvement in the root mean square (RMS) value of surface electromyography (sEMG) after treatment in both the control group and group A (t0.05), and the RMS value significantly improved in the groups B, C and D (t>8.983, P0.05), and they was better in the groups B, C and D than in the control group and group A (W>226.0, t>8.534, P306.0, t>3.663, P<0.05). Conclusion Acupuncture and low frequency electrical stimulation could effectively improve salivation in children with cerebral palsy, and their combination was superior to either ones, while OSMT did not show obvious benefit.

The Effect of A Salivation Stimulation Method on Xerostomia in Colon Cancer Patients after Surgery

PURPOSE: The aim of this study is to develop a salivation stimulation method and to verify the effect of a salivation stimulation method on xerostomia in colon cancer patients after surgery. METHODS: This study targeted 21 in the experimental group and 22 in the control group, who were diagnosed with colon cancer and underwent surgery at A university hospital. The salivation stimulation method consists of tongue movement for stimulating minor salivary glands in mouth and a parotid gland and submandibular gland massage with hands. The method was applied four times a day for 2 days the next day after surgery. RESULTS: On the first postoperative day, the experimental group showed a significantly larger amount of salivation than the control group (p=.010). On the second postoperative day, the experimental group showed a significantly larger amount of salivation than the control group (p<.001). On the first postoperative day, the subjective xerostomia scores in the experimental group and control group were not statistically significant (p=.165). On the second postoperative day, the experimental group showed a significantly lower subjective xerostomia score than the control group (p=.001). CONCLUSION: It is considered that providing cancer patients with this salivation stimulation method after surgery would reduce discomfort caused by xerostomia.
