OBJECTIVE To evaluate factors that are predictive of outcome for patients with chest wall soft-tissue sarcomas. PATIENTS AND METHODS A retrospective review of 55 surgically treated patients, from March 1964 to October 1996. RESULTS The median age of the patients was 47.5 years (age range, 15 to 76.3 years), and 56.4% were men. The most common presenting(More)
Two hundred fifty-four methicillin-resistant Staphylococcus aureus (MRSA) strains typed by pulsed-field gel electrophoresis (PFGE) were tested by PCR for the mec-associated hypervariable region (HVR-PCR) to determine their number of direct repeat units (DRUs). Eight different groups of repeats were found among the MRSA strains and compared to 28 pulsotypes(More)
The incidence of occult neck metastasis in early stage tumours of the tongue and floor of the mouth varies from 20% to 30%, and the survival rates in 5 years from 73% to 97%. This study analyzes the rates of occult metastasis and prognostic factors for clinical stages I and II squamous cell carcinoma of the tongue and floor of the mouth. The records of(More)
The aim of this study was to analyze the clinicopathological features and immunohistochemical expression of p53, MDM2, CDK4, PCNA and Ki67 proteins in 25 head and neck osteosarcomas registered in a single institution. The mean age of the patients was 29 years and the most common site was the mandible (60%). The predominant histological type was the(More)
Tuberculosis (TB) resurged in the late 1980s and an estimated 1.87 million people died of TB in 1997. The reemergence of tuberculosis as a public health threat, the high susceptibility of HIV-infected persons, and the proliferation of multidrug-resistant strains have created a need to develop new antimycobacterial agents. The existence of a shikimate(More)
OBJECTIVE To analyze the prognostic effect of epidermal growth factor receptor (EGFR), matrix metalloproteinases 2 and 9, and vascular endothelial growth factor expression in patients with locally recurrent oral carcinoma after salvage surgery. DESIGN Retrospective cohort study. Settings Tertiary center cancer hospital. PATIENTS The charts of 111(More)
The present paper shows, for the first time, the membrane expression of the dendritic cell maturation marker CD83 on tumor cells from lung cancer patients. CD83 was also detected on freshly cultured fibroblast-like cells from these tissues and on several adherent human tumor cell lines (lung adenocarcinomas P9, A459 and A549, melanomas A375 and C81-61,(More)
BACKGROUND The presence of regional lymph node metastasis has an important impact on clinical management and prognostication of patients with oral tongue squamous cell carcinoma (SCC). Approximately 30% to 50% of patients with oral tongue SCC have regional metastasis at diagnosis, but the limited sensibility of the current diagnostic methods used for neck(More)
CONTEXT Thyroid nodules are common in adult population and papillary thyroid carcinoma (PTC) is the most frequent malignant finding. The natural history of PTC remains poorly understood and current diagnostic methods limitations are responsible for a significant number of potentially avoidable surgeries. OBJECTIVE This study aimed to identify molecular(More)
Splenic metastasis is rare and generally associated with disseminated disease, often seen in breast cancer, colorectal and ovarian carcinoma, and melanoma. Isolated metastasis to the spleen is rare, with only 93 cases from all sources having been reported up to 2007. Moreover, isolated splenic metastasis from primary lung cancer is extremely rare, with only(More)
