The purpose of this study is to obtain experimental data on the possible changes that saliva may suffer when brought to low-level laser therapy protocols for analgesia in the masseter muscle, because this be on the Parotid salivary gland.
This study will examine whether the experimental drug AdhAQP1 can increase salivary flow in patients whose parotid glands have been exposed to therapeutic radiation for treatment of head and neck cancer. Radiation may damage the parotid glands (salivary glands located under the skin in front of the ear), leading to dry mouth, infections, excessive tooth decay, mouth sores, difficulty swallowing and pain. AdhAQP1 contains the human aquaporin-1 gene, which codes for a protein tha...
One of the side effects of standard radiation therapy for cancer of the nasopharynx is a permanent lessening of normal mouth moisture (saliva). This reduction in saliva is important because it causes a feeling of dry mouth, and has been shown to increase the risk of dental cavities and infections; change or decrease the ability to taste certain foods; and make chewing and swallowing food more difficult. Recent technical advances in radiation therapy offer the possibility of shi...
This randomized, controlled clinical trial, triple-blind, split-mouth type was conducted aiming to assess the absolute risk of sensitivity with and without sonic activation of a desensitizing gel previously to the in-office bleaching in adults.
A study of the complex genetics of brain development will be undertaken with an emphasis on those genes that cause the most common structural brain anomaly in humans called holoprosencephaly (HPE). This malformation of the brain can result from either environmental or genetic causes, and it is the aim of these investigations to determine the genes responsible for both normal and abnormal brain development through the study of patients with this disorder. Mutations in one such...
Xerostomia is a quantitative and qualitative alteration of saliva, a symptom present in individuals who make continuous use of medications to control chronic diseases, including hypertension. Difficulties in mastication, swallowing, phonation and palate are present, besides oral burning syndrome, periodontal disease, root caries and bad breath that will interfere in the quality of life, making it difficult to socialize in society. Currently, the methods presented for treatment ...
Liberal use of fine needle aspiration biopsy of parotid gland masses is controversial. All information regarding this procedure has been retrospective. Our objective is to evaluate prospectively the diagnostic accuracy of the test, alone and when associated to clinical and/or radiologic data.
Sonic hedgehog (Shh) signaling, including Gli1, is critical to treatment resistance. For optimizing cervical cancer treatment, the pathological prognostic factors determine whether to administer adjuvant therapy. However, the majority of clinical results was from squamous cell carcinoma, rendering conclusions for adenocarcinoma less convincing. We aimed to examine the role of Shh signaling in long-term clinical outcomes of cervical adenocarcinoma after receiving major surgery.
This study examines the effect of a small molecule inhibitor to the Sonic Hedgehog pathway on select hematologic malignancies. Part two of the study will examine the effect of this inhibitor in combination with dasatinib.
Ductal adenocarcinoma of the pancreas is the fifth leading cause of cancer related deaths in the European Union. Tumor markers CA19-9 and carcinoembryonic antigen are important components in decision making and follow-up of patients diagnosed with this disease. These tumor markers were found to be elevated not only in the serum but also in other body fluids in patients with malignant lesions of the parotid gland and the urinary tract. The authors have described in a previews s...
Therapeutic irradiation to the head and neck for cancer damages salivary glands present in the radiation field. Despite long recognition of radiation-induced salivary hypofunction, and the associated oral morbidities, the specific damage mechanism(s) is not known and the structure and functional integrity of the surviving parenchymal tissue has not been well-documented. Detailed knowledge of the latter is particularly necessary in order to design appropriate corrective therap...
Irradiation of the parotid gland with subsequent long-term xerostomia is a well-recognized complication after radiotherapy for head and neck (HAN) cancers. A number of studies have shown that IMRT could minimize the radiation dose to the parotid glands and hence the risk of developing xerostomia. The benefit of IMRT has also been demonstrated in prior dosimetric and non-randomized studies in NPC patients. In 2007, the investigators have published the prospective randomized stud...
The aim of this study is to compare the postoperative pain after root canal treatment following irrigation by endodontic needle, sonic and passive ultrasonic irrigation techniques.
The purpose of this study is to evaluate the efficacy of parotid sparing in reducing measurable xerostomia (dry mouth) in patients undergoing whole brain radiotherapy. This is primarily a two-arm, single-blind, randomized study of parotid sparing whole brain radiation therapy (WBRT), with a third observational arm of patients who were identified after radiation had already started or who refused randomization but were willing to be followed for quality of life assessment. Quali...
The purpose of this study is to demonstrate that orally administered itraconazole, a commonly used antifungal medication, can inhibit Hedgehog pathway signaling in patients with esophageal cancer, including adenocarcinoma (EAC) and squamous cell carcinoma (ESCC).
This study evaluates response of abnormal low salivary flow rate to transcutaneous electrical nerve stimulation (TENS) in diabetic type 2 patients. Response of saliva monitored for all participants receiving only one session of 5-minute extraoral TENS on bilateral parotid glands.
Obesity may affect periodontal health by inducing gingival oxidative damage through increased production in circulating reactive oxygen species (ROS). Previous studies have reported decreased glutathione levels in patients with periodontitis when compared to healthy subjects in gingival crevicular fluid (GCF), plasma and saliva. In the present study we hypothesized that high ROS levels in circulation may decrease glutathione levels in the GCF,plasma and saliva in obese patients...
A study correlating patient reported outcomes measured by a validated tool with physical measurements recorded by 3d photography of patients undergoing parotid resections
The purpose of this study is to document the safety of the Medtronic automatic periodic stimulating (APS) Electrode Stimulator during a parotidectomy and potentially prevent post-operative facial nerve weakness, which is a relatively common outcome after parotid surgery.
This clinical trial is looking at the effect of a new drug called GDC-0449 in patients with cancer of the pancreas. Laboratory studies have shown that this drug blocks a process in pancreatic cells thought to be involved in cancer development and spread. This process is called the 'Hedgehog signalling pathway'. As yet, it is unclear whether blocking hedgehog signalling will directly affect the tumour cells themselves or the surrounding normal tissue. Understanding this distinct...
This study proposes to demonstrate the feasibility of measuring 2H:1H and 18O:16O in saliva and breath by comparing the natural abundances of 2H:1H and 18O:16O in saliva and urine of un-dosed humans.
This is an open-label, single arm, multi-center, Phase II trial to evaluate the progression free survival in patients with metastatic adenocarcinoma of the pancreas treated with a hedgehog inhibitor (GDC-0449) in combination with chemotherapy (gemcitabine and nab-Paclitaxel).
The purpose of the study is to perform the first clinical trial on human subjects using the Sonic Flashlight (SF) to guide placement of Peripherally Inserted Central Catheters (PICCs).
The purpose of this study is to compare the levels of Substance P in saliva, in patients with severe chronic low back pain and in subjects without it. In addition, to explore a possible cutoff point, in order to define normal and pathological levels of Substance P in saliva. The ultimate objective would be to design a measurement method for use in routine clinical practice.
The goal of this project is to identify specific miRNAs that are increased or decreased in the saliva of children with developmental delay and are useful for screening toddlers for ASD. Such a screening tool would improve the specificity of diagnosis, streamline referrals to developmental specialists, and expedite the arrangement of early intervention services.
