Brazilian organic propolis for prevention and treatment of radiation-related oral acute toxicities in head and neck cancer patients: A double-blind randomized clinical trial.

Oral mucositis (OM) is one of the most important acute toxicities from radiotherapy (RT) in head and neck cancer patients and can impair oncologic treatment. Dysphagia, dysgeusia, pain, and oral candidiasis are other common toxicities. Brazilian Organic Propolis (BOP) is a recently described propolis variant and BOP types 4 and 6 have shown important antioxidant, anti-inflammatory, and antifungal properties.

The impact of an educational video about radiotherapy and its toxicities in head and neck cancer patients. Evaluation of patients' understanding, anxiety, depression, and quality of life.

Objectives: Head and neck radiotherapy can cause several toxicities, and its management has important treatment implications. Proper information about treatment is crucial to assist patients by preparing them and enhancing their ability to manage their illness. Thus, this study aimed to verify the impact of an educational video on the improvement of the patient's understanding, satisfaction, quality of life, and influence on their emotional state in different moments of treatment.

Oral carcinoma development after 23 years of renal transplantation.

Renal transplant patients are treated with immunosuppressive drugs that decrease the effectiveness of the immune system, making them more prone to developing cancer. Skin and lip carcinomas are common malignancies encountered after transplantation, whereas oral carcinomas are rare. We report the case of a 51-year-old female Caucasian patient, with no history of smoking, who presented white lesions on the tongue and an ulcerated lesion on the lower lip beginning 4 months prior.

A series of 33 older patients with lip venous lake treated by sclerotherapy.

Background: Venous lake lesion is a venous ectasia that can occur on the lips of older people. Although different therapies have been used, there is no guideline for treating this lesion. The purpose of this study was to evaluate whether sclerotherapy is an effective and acceptable option for treatment of venous lake lesions of the lips in older patients.

Oral manifestations of Langerhans cell histiocytosis: A case series.

Aim: Langerhans cell histiocytosis (LCH) is an unusual proliferative disorder of bone marrow-derived histiocytes (Langerhans cells) that can produce focal or systemic manifestations. Oral manifestations of LCH can present as single or multiple lesions and can be a challenge in clinical practice. The aim of this paper is to present the clinicopathological features of a series of nine patients with oral involvement.

Florid osseous dysplasia associated with multiple simple bone cysts: a patient with 22 years of follow-up.

Florid osseous dysplasia (FOD) has been described as a condition that typically affects the jaws of middle-aged women of African descent and usually presents as multiple radiopaque masses distributed throughout the jaws. The diagnosis is generally based on clinical and radiographic presentation, often involving various regions of the jaws without evident bone expansion. This article describes the course of FOD in a 27-year-old African-American woman during 22 years of follow-up, emphasizing the dynamic radiographic characteristics of this entity and unusual co-occurrence with multiple simple bone cysts.

Intraosseous Non-Hodgkin Lymphoma Mimicking a Periapical Lesion.

Non-Hodgkin lymphomas are a group of disorders involving malignant monoclonal proliferation of lymphoid cells, which appear at extranodal sites in approximately 40% of the cases, particularly in the gastrointestinal tract. Intraosseous lymphomas of the head and neck region are extremely rare and can mimic other diseases such as periodontitis or periapical pathologies. This report presents an additional case of intraosseous lymphoma that was previously misdiagnosed as periapical disease.

Neuropathic pain after brachial plexus avulsion--central and peripheral mechanisms.

Review: The pain that commonly occurs after brachial plexus avulsion poses an additional burden on the quality of life of patients already impaired by motor, sensory and autonomic deficits. Evidence-based treatments for the pain associated with brachial plexus avulsion are scarce, thus frequently leaving the condition refractory to treatment with the standard methods used to manage neuropathic pain. Unfortunately, little is known about the pathophysiology of brachial plexus avulsion.

Repetitive transcranial magnetic stimulation in chronic pain: a review of the literature.

Objective: To review the literature on the analgesic effects of repetitive transcranial magnetic stimulation (rTMS) in chronic pain according to different pain syndromes and stimulation parameters.

Data Sources: Publications on rTMS and chronic pain were searched in PubMed and Google Scholar using the following key words: chronic pain, analgesia, transcranial magnetic stimulation, neuropathic pain, fibromyalgia, and complex regional pain syndrome.

Study Selection: This review only included double-blind, controlled studies with >10 participants in each arm that were published from 1996 to 2014 and written in English.
