For both treatments, HER-2 overexpression was a significant negative prognostic factor for DFS but not for OS, while high expression of VEGF was not significantly associated to either DFS or OS. No predictive ability of HER-2 status or VEGF overexpression for T treatment was evident.
Primary malignant melanoma is only rarely found in the oral cavity (estimated at between 0.2 and 8 per cent of all melanomas) and occurs approximately four times more frequently in the oral mucosa of the upper jaw, usually on the palate or alveolar gingivae. A case is reported of a malignant melanoma in the mouth of a 74 year old male, which was originally diagnosed as reactive denture hyperplasia caused by a ill-fitting upper denture. Correction of the denture fault failed to stop the growth of the mass, which was therefore removed surgically. Histological examination revealed a melanin-producing tumour. A partial maxillectomy was performed and there was no evidence of recurrence over a three year follow-up period.
IntroductionHydrocarbon pneumonitis is an acute, intense pneumonitis resulting from aspiration of volatile hydrocarbon compounds with low viscosity and surface tension, most of which are members of the paraffin, naphthene and aromatic classes.Case presentationSix hours after participating in a party for teenagers, a 16-year-old boy developed dyspnea, cough, a fever (39°C) and chest pain. A chest radiograph showed infiltration in the right middle lobe. The patient reported alcohol abuse during the party and an episode of vomiting a few hours thereafter. He also reported practicing a fire-eating performance at the party using liquid paraffin, but was unaware of inhaling any of it. The radiographic infiltration was diagnosed as an aspiration pneumonia and he was treated at the local health center with antibiotics. Five days later, because of clinical deterioration, he was referred to a pulmonary clinic. A chest computed tomography scan was performed which showed consolidation with an air bronchogram in the right middle lobe and areas of atelectasis and ground glass opacities in the middle and lower right lobes. Spirometry revealed severe restriction of lung function. A bronchoscopy revealed inflamed, hyperemic mucosa. Bronchoalveolar lavage fluid revealed lipid-laden alveolar macrophages, which were detected by lipid staining, and neutrophilia. The patient was finally diagnosed with hydrocarbon pneumonitis and he was treated with systemic steroids and antibiotics. After 6 days of treatment there was complete clinical and significant radiologic regression.ConclusionHydrocarbon pneumonitis should be included in the differential diagnosis of pneumonias. Recent exposure to volatile hydrocarbons provides a basis for clinical diagnosis, as symptoms and radiologic findings are not specific.
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.
