Prevalence of HPV16 L1 protein in oral biopsies: A diagnostic study from Ecuador.

This study was designed to investigate the expression of HPV16 L1-protein in biopsies of oral mucosa samples. The expression of HPV16 L1 protein was investigated in biopsies taken from oral mucosa from patients who required pathological diagnosis of oral lesions. Seventy-two samples were incubated with anti-L1 protein monoclonal antibodies and protein detection was revealed with diaminobenzidine. Expression of L1 protein was performed by a pathologist blinded for tissue diagnosis under light microscopy. Most of the lesions of oral mucosa were present in lining mucosa (75 %) and the most frequent lesion were mucocele (n = 17, 23.6 %), epithelial hyperplasia (n = 6, 8.33 %), fibroma (n = 5, 6.9 %) and inflammatory hyperplasia (n = 5, 6.9 %). L1 protein expression was observed only in five (6.9 %) samples (two squamous cell carcinomas, two epithelial hyperplasia, and one gingival hyperplasia). We concluded that L1 expression in oral biopsies presented a low frequency in oral mucosal biopsies samples.

Oral Hygiene of Patients with Cancer in the Intensive Care Unit / Higiene Bucal de Pacientes com Câncer em Unidade de Terapia Intensiva

Dental care in Intensive Care Units - ICU, plays an important role in maintaining the health and well-being of critically ill patients. Although infection is a frequent manifestation in Intensive Care Unit (ICU) patients, the risk of infection by the oral cavity should also be considered. The immune response of this patient may be compromised, and consequently latent infections may intensify. The mouth is considered an ideal microbial incubator because of its characteristic of pH, presence of nutrients and hard surfaces. The relationship between periodontal disease and systemic conditions, including lung infections, is being explored. This study had the purpose of evaluating the odontology conditions in hospitalized patients with cancer in an intensive care unit at the Cancer Hospital of Londrina - Paraná, Brasil, quantifying the oral microbiota and evaluating bacterial resistance. Inclusion criteria involved critical patients of both sexes, two male and two female, ranging from 40 to 80 years old, submitted to mechanical endotracheal breathing. The presence of visible biofilm and xerostomia were the most prevalent. The results obtained are three patients who presented Klebsiella pneumoniae producer of Carbapenemase, due to the oral hygiene deficiency in patients hospitalized in the ICU, which are responsible for major systemic complications, increasing hospitalization time.(AU).

O atendimento odontológico nas Unidades de Terapia Intensiva - UTI, tem papel importante na manutenção da saúde e bem-estar dos pacientes criticamente doentes. Embora a infecção seja uma manifestação frequente em pacientes de Unidade de Terapia Intensiva (UTI), o risco de infecção pela cavidade bucal também deve ser considerado. A resposta imune desse paciente pode ser comprometida e consequentemente infecções latentes podem intensificar. A boca é considerada uma incubadora microbiana ideal devido à sua característica de pH, presença de nutrientes e superfícies duras. A relação entre doença periodontal e condições sistêmicas, incluindo infecções pulmonares, está sendo explorada. Este estudo teve a finalidade de avaliar as condições odontológicas em pacientes com câncer internados em unidade de terapia intensiva do Hospital do Câncer de Londrina estado do Paraná, Brasil, quantificando a microbiota bucal e avaliando a resistência bacteriana. Os critérios de Inclusão envolveram pacientes críticos de ambos sexos, dois masculinos e dois femininos com idade variando dos 40 aos 80 anos, submetidos à respiração mecânica endotraqueal. A presença de biofilme visível e xerostomia foram a alteração mais prevalente. Nos resultados obtidos encontrou-se três pacientes que apresentaram Klebsiella pneumoniae produtoras de Carbapenemase, pela deficiência de higienização bucal nos pacientes internados na UTI, que são responsáveis por grandes complicações sistêmicas, aumentando o tempo de internamento.(AU).
