Background: Drooling is the unintentional loss of saliva from the mouth, usually caused by poor coordination of the swallowing mechanism. It is commonly seen in patients with chronic neurologic disorders, such as Parkinson's disease, amyotrophic lateral sclerosis (ALS), cerebral palsy, and stroke, as well as in patients with cognitive impairment and dementia.

Objectives: To evaluate the efficacy and safety of ultrasound-guided botulinum toxin injections into the parotid and submandibular salivary glands for the treatment of drooling.

Methods: We conducted a retrospective analysis of the medical records of 12 consecutive patients treated with botulinum toxin injections into the parotid and submandibular glands for the first time. The primary outcome variable was the subjective improvement of drooling on a 5-point scale. Secondary outcome variables were duration of the therapeutic effect, request to undergo additional treatment, and adverse events.

Results: Of 12 patients, 8 (67%) reported considerable improvement after treatment, 3 reported slight improvement, and 1 reported development of dry mouth. All patients stated that they felt the effects 1 week after the injections; the mean duration of the therapeutic effect was 4.5 months (range 3–9 months). One patient suffered from local hematoma and ecchymosis that did not require medical care. Another patient complained of difficulty swallowing, which did not require medical treatment and resolved spontaneously within 1 month.

Conclusions: Ultrasound-guided botulinum toxin injections into the parotid and submandibular glands seem to be a safe and effective therapy for the treatment of drooling. Further long-term prospective studies with varying doses are warranted.

Background: The congenital absence of salivary glands has been reported in children but never in fetuses with trisomy 21.

Objectives: To determine whether the congenital absence of salivary glands can be detected prenatally between 13 and 16 weeks of gestation in normal and trisomy 21 fetuses using transvaginal ultrasound. 

Methods: We performed a retrospective analysis of recordings of normal and trisomy 21 fetuses. Inclusion criteria were a single viable fetus and good visualization of the anatomic area of the salivary glands on both sides of the fetal face. All videos were reviewed by one examiner who reported the presence or absence of one or more salivary glands and was blinded to the fetal karyotype.

Results: Of the 45 videos reviewed, 4 were excluded from the study: namely, a non-viable fetus, twin pregnancy, and in 2 there was unsatisfactory visualization of the anatomic area of the salivary glands. Of the remaining 41 fetuses, 24 had trisomy 21 and 17 were normal. In the trisomy 21 fetuses, 8 (33.3%) had congenital absence of one or more salivary glands compared to 1 of 17 normal fetuses (5.9%) (P < 0.05). 

Conclusions: Congenital absence of the salivary glands has a high specificity but low sensitivity for detecting trisomy 21 fetuses.

In recent years, salivary gland ultrasonography (SGUS) has emerged as a promising tool for the diagnosis and prognostic stratification of patients with primary and secondary Sjögren’s syndrome. Several studies have emphasized that salivary ultrasonography could be a highly specific tool for the diagnosis of the disease. However, before it can be used in daily clinical practice the SGUS procedure needs standardization and validation in larger disease-control groups. In this review we provide an update on the role of SGUS in the diagnostic algorithm of primary Sjögren’s syndrome.

Patients with graft-versus-host disease suffer from xerostomia, oral infections and mucosal pathologies. The continuous increase in the number of patients treated worldwide with bone marrow transplants, combined with improved survival statistics result in a concomitant increase in the number of GVHD[1] patients. the pathogenesis of GVHD is based on donor graft T lymphocytes that recognize antigenic disparities between donor and recipient, and on the disregulation of a broad panel of cytokines. Consequently, various tissues and organs, including the mucosa of the oral and gastrointestinal tract, are damaged via cytotoxicity caused by infiltrating T cells. Since the salivary glands are a known major target of GVHD and their secretions significantly contribute to preserving mucosal integrity, this mucosal insult is further enhanced by the reduced quantity and altered quality of saliva. GVHD occurs in 40–70% of patients treated by bone marrow and peripheral blood stem cell transplantation. limited studies suggest that a large percentage of GVHD patients are affected and that the induced salivary dysfunction occurs rapidly following transplantation, affecting both major and minor salivary glands and reflecting the severity of the disease. Moreover, profound sialochemical alterations may be diagnostic of GVHD. an additional reason for the vast amount of research is that GVHD, as an autoimmune-like disease, seems to be an appropriate model for studying a much more prevalent, well-known and studied autoimmune disease involving salivary glands, namely, sjögren’s syndrome. The present review describes the GVHD-related sialometric and sialochemical data available in the literature for both major and minor salivary glands in both human and rodent models, and discusses a possible mechanism.

Background: Fine-needle aspiration is a widely accepted method in the preoperative evaluation of head and neck tumors. However, its effectiveness in the interpretation of salivary gland disorders is controversial.

Objectives: To evaluate the effectiveness of FNA[1] as a preoperative diagnostic tool of parotid lesions.

Methods: Reports of 52 FNA from various parotid gland lesions were compared with the final pathologic diagnoses.

Results: We noted 31 true-positive, 5 true-negative and 16 false-negative results. There were no false-positive FNA reports. The calculated sensitivity, specificity and accuracy of FNA diagnosis in this study were 66%, 100%, and 69.2% respectively.

Conclusions: The high rate (30.8%) of false-negative FNA results was partly explained by sampling errors, therefore specificity of the procedure could be improved by the precise selection of a representative aspiration site.
