Neurological diseases can be complicated by sialorrhea, an excessive flow of saliva. Patients suffering from moderate to severe sialorrhea have an impaired quality of life, often worsened by correlated complications such as aspiration pneumonia, oral infections, dental caries, and maceration of the skin. Diverse therapeutic approaches have been proposed for the treatment of sialorrhea, including surgery and the use of anticholinergic agents, with limited results and the possible occurrence of serious adverse events...

BACKGROUND: Sublingual immunotherapy (SLIT) is a safe and effective treatment for allergic rhinitis (AR). However, many issues regarding SLIT remain to be resolved, including the optimal timing of administration. This study investigated the effect of time of day on SLIT efficacy with the goal of optimizing the therapeutic outcome. METHODS: We performed prophylactic SLIT at different times of day (10 a.m. or 10 p.m.) in 2 mouse models of AR: an ovalbumin (OVA)-induced AR model and Cry j 1-induced AR model, and compared the effects...

#6
Ahmed Gaber Hassanein, Ahmed M A Abdel Mabood
PURPOSE: During surgery for major maxillofacial fractures, orotracheal intubation can interfere with some surgical procedures and nasal intubation can be contraindicated or impossible. That is why tracheotomy is presented as a solution, although it carries a relatively high incidence of complications. In this study, the use of submandibular tracheal intubation is basically evaluated as an alternative to tracheotomy in such circumstances. MATERIALS AND METHODS: This prospective study was performed in patients undergoing surgery for major maxillofacial fractures in which oral intubation and/or nasal intubation have been unsuitable, impossible, or contraindicated...

BACKGROUND: Retinoic Acid (RA), the active metabolite of Vitamin A, has been demonstrated to be important for growth and branching morphogenesis of mammalian embryonic salivary gland epithelium. However, it is not known whether RA functions directly within epithelial cells or in associated tissues that influence morphogenesis of salivary epithelium. Moreover, downstream targets of RA regulation have not been identified. RESULTS: Here we show that canonical RA signaling occurs in multiple tissues of embryonic mouse salivary glands, including epithelium, associated parasympathetic ganglion neurons, and non-neuronal mesenchyme...

Onabotulinum toxin A (OBTXA) is an effective treatment for drooling. Our objective was to determine if there are histologic changes in the submandibular glands (SMGs) after repetitive OBTXA injections. The study included blinded histologic analysis and comparison of SMGs with ≥4 OBTXA injections versus controls who never received OBTXA. The number of acinar cells were counted, and the morphology of the cells was evaluated within each histologic sample of the SMGs. Thirty-one glands were analyzed (14 control, 17 cases)...

The differential diagnosis for inflammatory neck swellings is vast. A swelling of dental origin should be considered because, while rare, they mimic more common causes of neck lumps. We report the case involving a recurrent submandibular swelling in a young female patient that was presumed to be an epidermoid cyst by her general medical practitioner. After 6 months of unsuccessful treatment in the community, an odontogenic source was identified and treated successfully following referral to a local Oral and Maxillofacial department...

Castleman disease (CD), a benign lymphoproliferative disorder that affects lymph nodes, is uncommon in children, with only approximately 100 cases published. Although 23% of pediatric CD cases are found in the neck, there is no substantial reported percentage found in the salivary glands, especially the submandibular salivary gland (SMSG). A pediatric case of CD involving the SMSG is reported because of its extreme rarity.

Infection with Group A streptococcus (GAS)-an oropharyngeal pathogen-leads to mortality and morbidity, primarily among developing countries and indigenous populations in developed countries. The development of safe and affordable GAS vaccines is challenging, due to the presence of various unique GAS serotypes, antigenic variation within the same serotype, and potential auto-immune responses. In the present study, we evaluated the use of a sublingual freeze-dried (FD) formulation based on immunogenic modular virus-like particles (VLPs) carrying the J8 peptide (J8-VLPs) as a potential safe and cost-effective GAS vaccine for inducing protective systemic and mucosal immunity...

The aim of this study was to compare mandibular form (i.e., size and shape) between patients with agenesis of the lower second premolar (P2) and a control group with no agenesis. Three hypotheses were tested: (H1) agenesis causes a change in mandibular morphology because of inadequate alveolar ridge development in the area of the missing tooth (mandibular plasticity); (H2) agenesis is caused by spatial limitations within the mandible (dental plasticity); and (H3) common genetic/epigenetic factors cause agenesis and affect mandibular form (pleiotropy)...

BACKGROUND: Marketing new radiography devices necessitates documenting their absorbed X-ray doses. Since the current literature lacks studies on new devices, we assessed the doses of two new devices that had not previously been assessed. OBJECTIVES: The new devices were compared to the Promax three dimensional (3D) scanner at two fields of view (FOV) in nine critical head and neck tissues and organs. MATERIALS AND METHODS: Seventeen thermoluminescence dosimeters positioned in an average-sized male RANDO phantom were used to determine the dosimetry of the three cone beam computerized tomography devices (NewTom VGi, NewTom 5G, and Promax 3D) at two field of views (FOVs), one small and one large...

BACKGROUND: Mouse models have served a valuable role in deciphering various facets of Salivary Gland (SG) biology, from normal developmental programs to diseased states. To facilitate such studies, gene expression profiling maps have been generated for various stages of SG organogenesis. However these prior studies fall short of capturing the transcriptional complexity due to the limited scope of gene-centric microarray-based technology. Compared to microarray, RNA-sequencing (RNA-seq) offers unbiased detection of novel transcripts, broader dynamic range and high specificity and sensitivity for detection of genes, transcripts, and differential gene expression...
