“…Another field of interest in connection with salivary gland US is the diagnosis of juvenile SS. US is an effective diagnostic or prognostic tool for different pathologies (132) but it is even frequently applied for invasive procedures (44,133).…”

“…All Doppler US techniques can be used in salivary glands pathology. Using color Doppler, the speed and direction of moving blood cells can be determined, while power Doppler US provides high sensitivity in detection the slow flow (44). High vascularization is generally associated with the suspicion of malignancy and low vascularization may be considered a sign of benign behaviour (45).…”

Disorders affecting parotid gland represent a heterogeneous group comprising congenital, inflammatory and neoplastic diseases which show a focal or diffuse pattern of appearance. The differentiation of neoplastic from non-neoplastic conditions of parotid glands is pivotal for the diagnostic imaging. Frequently there is evidence of overlapping between the clinical and the imaging appearance of the various pathologies. The parotid gland is also often object of study with the combination of different techniques [ultrasound-computed tomography-magnetic resonance imaging (US-CT-MRI), ex.]. Compared to other dominant methods of medical imaging, US has several advantages providing images in real-time at lower cost, and without harmful use of ionizing radiation and of contrast enhancement. B-mode US, and the microvascular pattern color Doppler are usually used as first step evaluation of parotid lesions. Elastography and contrast-enhanced US (CEUS) has opened further possible perspectives to improve the differentiationbetween benign and malignant parotid lesions. The characterization of the parotid tumors plays a crucial role for their treatment planning and for the prediction of possible surgical complications. We present, here an updated review of the most recurrent pathologies of parotid gland focusing on the diagnostic power of multiparametric US including CEUS and ultrasound elastography (USE); limitations, advantages and the main key-points will be presented

Background: The current study has been conducted to estimate the impact of Catha Edulis Forsk (simply known as khat) on pH and saliva flow rate in teeth unaffected by caries among patients from Arab, Yemen, consuming the plant. The goal was to evaluate the relation of these indicators with gene manifestation of CHRM1 and CHRM3, which contributes to the regulation of saliva secretions. Methods: Overall, 60 respondents aged between 27 and 54 years were selected for the research. They were distributed among two groups, group I and group II, including 30 respondents equally. Group I incorporated respondents consuming no khat, having teeth caries, adequate saliva flow, and generally, healthy oral cavity. In turn, group II incorporated respondents consuming khat having caries-free teeth, inadequate saliva flow and relatively unhealthy oral cavity. Saliva samples were taken from all respondents. They were analyzed for indicators of flow rate as well as pH of saliva. Salivary gland biopsy specimens have also been taken. The whole RNA was allocated, cDNA synthesized and reinforced to estimate the gene manifestation of CHRM1 and CHRM3. Results: A considerable rise in the mean salivary flow rate along with a drastic decline in the mean salivary pH within caries-free teeth among the respondents consuming khat was observed during the study. The mRNA expressions CHRM1 and CHRM3 were significantly increased among participants consuming khat. Results were contrasted to the control group of patients not consuming khat. Conclusion: The characteristics of salivary flow rate, pH, and caries-free teeth have been related to the gene manifestations of CHRM1 and CHRM3 in respondents consuming khat.
