A 39-year-old woman drank one tablespoon of white vinegar in order to 'soften' crab shell stuck in her throat. Endoscopy revealed inflammation of the oropharynx and second-degree caustic injury of the oesophagus extending to the cardia. She had an uneventful recovery. This case report confirmed that vinegar could cause ulcerative injury to the oropharynx and oesophagus. The folklore application...

Fiberoptic imaging was performed in six decerebrate, tracheotomized cats to determine the effect of pharyngeal muscle activation on the pharyngeal airway. The fiberoptic scope was advanced through the rostral trachea into the pharynx. Computer-based planimetry was used to measure airway area and maximum anteroposterior and lateral diameters in the rostral oropharynx, velopharynx, and caudal oro...

INTRODUCTION Molecular studies about carcinomas of the oral cavity and oropharynx demonstrate the presence of human papilomavirus genome in these tumors, reinforcing the participation of human papilomavirus in oral carcinogenesis. OBJECTIVES This study aimed to determine the prevalence of human papilomavirus and genotype distribution of HPV16 and HPV18 in oral cavity and oropharynx carcinomas...

Respiratory infections are well-known triggers of chronic respiratory diseases. Recently, culture-independent tools have indicated that lower airway microbiota may contribute to pathophysiologic processes associated with asthma and chronic obstructive pulmonary disease (COPD). However, the relationship between upper airway microbiota and chronic respiratory diseases remains unclear. This study ...

BACKGROUND Neisseria lactamica as one of the main commensal in oropharynx during the childhood is related to the induction of a natural immunity against meningococcal meningitis. Also Moraxella catarrhalis in oropharynx of children is a predisposing factor for otitis media infection. OBJECTIVES The current study aimed to investigate the frequency of the N. lactamica, other nonpathogenic Neiss...

Cytomegalovirus (CMV) is a common opportunistic infection in both iatrogenic and HIV-induced immunosuppression. The usual sites of involvement are the gastro-intestinal tract, retina and lung. We present three cases of CMV ulceration of the oropharynx. All three patients presented with symptoms localized to the oropharynx and in each case the diagnosis was only made on histological examination ...

Southeastern Yunnan has 4,996 species and varieties of 1,357 genera and 186 families of native seed plants recorded. Floristic attributes and biogeographical affinities of the flora were studied by analyzing its floristic composition and geographical elements. Tropical genera comprise a majority (68.83%) of the flora and those of tropical Asian distribution contribute to 27.34% of the total gen...
