These results showed that radiation injuries affect the bone and surrounding soft tissues. However, the irradiation-induced injuries, such as cellular loss (hypocellularity) and fibrosis, were more expressive in bone tissue than in the surrounding soft tissues.
This is the first report about the participation of murine mast cells as phagocytes against A. actinomycetemcomitans, mainly in the absence of opsonization with human serum. Our results may indicate that mast cells act as professional phagocytes in the pathogenesis of biofilm-associated periodontal disease.
Papillary cystadenoma is a rare, benign salivary gland tumor which is well-circumscribed, containing cystic cavities with intraluminal papillary projections. Only 19 cases arising within minor salivary glands (MnSG) from the oral cavity sites have been reported in the English literature (PubMed 1958-2014). We report 11 new cases of MnSG papillary cystadenomas in conjunction with a review of the literature. Demographic information, clinical and histologic features, treatment and prognosis are compiled and discussed for all 30 cases reported in the English literature.
Objective This a cross-sectional study to evaluate the association between oral health findings and ventilator-associated pneumonia (VAP) among critically ill patients in intensive care units (ICU). Material and methods Data were collected from medical records, and a detailed oral physical examination was performed on 663 critically ill patients on mechanical ventilation. Data were statistically analysed using univariate and logistic regression models relating the development of VAP with the oral findings. Results At oral physical examination, the most frequent findings were tooth loss (568-85.67%), coated tongue (422-63.65%) and oral bleeding (192-28.96%). Patients with a coated tongue or oral bleeding on the first day of ICU hospitalization developed more VAP than did patients without these conditions (20.14 vs 13.69%, p = 0.02; 23.44 vs 15.50%, p = 0.01, respectively). In the logistic regression, a coated tongue and oral bleeding were considered independent risk factors for VAP development (OR = 1.61 (1.03-2.51) and OR = 1.69 (1.08-2.66), respectively). Conclusions The presence of a coated tongue and oral bleeding in ICU admission could be considered markers for the development of VAP. Clinical relevance The results of this paper reinforce the importance of proper maintenance of oral hygiene before intubation, which may lead to a decrease in the incidence of VAP in the ICU.
Objective: This a cross-sectional study to evaluate the association between oral health findings and ventilator-associated pneumonia (VAP) among critically ill patients in intensive care units (ICU). Material and Methods: Data were collected from medical records, and a detailed oral physical examination was performed on 663 critically ill patients on mechanical ventilation. Data were statistically analysed using univariate and logistic regression models relating the development of VAP with the oral findings. Results: At oral physical examination, the most frequent findings were tooth loss (568 - 85.67%), coated tongue (422 - 63.65%) and oral bleeding (192 - 28.96%). Patients with a coated tongue or oral bleeding on the first day of ICU hospitalization developed more VAP than did patients without these conditions (20.14% vs 13.69%: p=0.02; 23.44% vs 15.50%: p=0.01, respectively). In the logistic regression, a coated tongue and oral bleeding were considered independent risk factors for VAP development [OR=1.60 (1.02-2.47) and OR=1.59 (1.05 – 2.44), respectively]. Conclusions: The presence of a coated tongue and oral bleeding in ICU admission could be considered markers for the development of VAP. Clinical relevance: The results of this paper reinforces the importance of proper maintenance of oral hygiene before intubation, which may lead to a decrease in the incidence of VAP in the ICU. This is particularly important in the COVID-19 current scenario, where more people are expected to need mechanical ventilation, consequently increasing cases of VAP.
Vascular malformations (VMs) are benign lesions of blood vessels originated from an error in vascular morphogenesis during the embryologic phase. Generally, when located in the head and neck region VMs occurs in lips, tongue, buccal mucosa, gums, or palate. The VMs are usually asymptomatic, varies in size and may cause facial asymmetries. Different therapeutic modalities are available to treat VMs, which include surgical excision, cautery, cryotherapy, laser therapy, and sclerosing agents. The authors report 2 patients with extensive VM in the tongue treated with intralesional injection of a low-dose solution of monoethanolamine oleate (MO) and lidocaine. The first patient was a 69-year-old male patient and the 2nd a 65-year-old woman. In both patients, it were performed weekly application of 1:1 MO (Ethamolin) with Lidocaine (lidocaine 3% 1:50,000) in the amount of 0.1 mL of the solution per cm3 of lesion, with a total of 12 applications for each patient at the end of the treatment, with good results and without complications. It is important to be alert in which situation sclerotherapy should be used and that small doses of the sclerotherapeutic agent is essential for the prevention of complications after the procedure. Therefore, these patients showed that the sclerotherapy with MO may be an effective and simple treatment for extensive oral benign vascular lesions. In both patients, there was a great improvement in the clinical aspect of the lesions and patient's satisfaction.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
