BACKGROUND The aim of this study was to evaluate the expression of IMP3, an independent poor prognostic factor for many cancers, and its association with clinicopathological features and HER2 status. METHODS Gastrectomy specimens from 106 patients were evaluated by immunohistochemistry and fluorescence in situ hybridization. RESULTS HER2 overexpression(More)
INTRODUCTION Pegylated Interferon Alpha (Peg-IFN) in combination with other drugs is the standard treatment for chronic hepatitis C infection (HCV) and is related to severe painful symptoms. The aim of this study was access the efficacy of transcranial direct current stimulation (tDCS) in controlling the painful symptoms related to Peg-IFN side effects. (More)
PURPOSE It has been reported that the oral squamous cell carcinoma (OSCC) in tongue shows a more infiltrative profile, aggressive clinical course and poor prognosis, which may be related to a higher metastatic potencial. The aim of the present study was to assess the expression of β-catenin in OSCC of the tongue and its correlation with tumor metastasis. (More)
Melanoma is the most aggressive and lethal form of skin cancer, responsible for >80% of deaths. Standard treatments for late-stage melanoma usually present poor results, leading to life-threatening side effects and low overall survival. Thus, it is necessary to rethink treatment strategies and design new tools for the treatment of this disease. On that(More)
Background: Central post stroke pain (CPSP) is a highly refractory syndrome that can occur after stroke. Primary motor cortex (M1) brain stimulation using epidural brain stimulation (EBS), transcranial magnetic stimulation (TMS), and transcranial direct current stimulation (tDCS) have been explored as potential therapies for CPSP. These techniques have(More)
Use of imaging tools like digital C-arm, tridimensional tomography, and navigational surgery has proven its value to the surgical removal of broken needles. A 32-year-old patient was referred for evaluation of a fractured needle during inferior alveolar nerve block attempt few days before. The patient complained of a pricking sensation at the injured area(More)
The authors report a case of mucocutaneous leishmaniasis in a 45-year-old patient who was unsuccessfully treated with pentavalent antimonial for 30 days.

AIM Epidermolysis bullosa (EB) represents a highly rare subgroup of skin diseases that affects skin and mucous membrane. The aim of the present study was to assess caries prevalence and its associated factors in EB subjects. Salivary status was also assessed. MATERIALS AND METHODS Ten subjects with EB who were under supervision were selected (cases) and(More)
The balance between matrix metalloproteinases (MMP) and their tissue inhibitors (TIMP) plays a key role in the development of hypertension and obesity. We aimed to evaluate the levels of MMP-2 and 9 and TIMP-2 and -1 in obese and non-obese apparent treatment-resistant hypertensive subjects (aTRH) and its association with cardiac hypertrophy.
