Mycobacterium leprae on Palatine Tonsils and Adenoids of Asymptomatic Patients, Brazil.

We investigated palatine tonsil and adenoid specimens excised from otorhinolaryngological patients in a leprosy-endemic region of Brazil. Fite-Faraco staining identified Mycobacterium spp. in 9 of 397 specimen blocks.

Linear verrucous epidermal nevus with oral manifestations: report of two cases.

Linear verrucous epidermal nevi (LVEN) are characterized by verrucous papules often coalescing into well-demarcated skin-colored or brown plaques following the lines of Blaschko. We present two new cases of LVEN with oral mucosa involvement and briefly discuss this very rare finding. In both cases, oral biopsies showed hyperkeratosis, acanthosis, and papillomatosis.

Dermatologic manifestations of infective endocarditis.

Despite advances in diagnosis and treatment, infective endocarditis still shows considerable morbidity and mortality rates. The dermatological examination in patients with suspected infective endocarditis may prove very useful, as it might reveal suggestive abnormalities of this disease, such as Osler's nodes and Janeway lesions. Osler's nodes are painful, purple nodular lesions, usually found on the tips of fingers and toes.

Mucoadhesive propolis gel for prevention of radiation-induced oral mucositis.

The objective of this phase II study was to determine the effectiveness of a mucoadhesive propolis gel in the prevention of radiation-induced oral mucositis. Twenty-four patients who were selected to undergo radiation therapy for oral cancer were included in this open-label trial. They were advised to use a mucoadhesive gel containing propolis 5,0% w/v three times a day starting one day before the course of radiation therapy and concluding after 2 weeks of radiation therapy.

Primary hepatic lymphoma: A case report.

Introduction: Primary hepatic lymphoma is a rare malignancy which misdiagnosis and mistreatment is very frequent. Differential diagnosis of the hepatic lesion, based on the noninvolvement of blood vessels, includes: fatty infiltration, cirrhosis, amyloid infiltration, primary hepatomas, and metastatic neoplasms.

Presentation Of Case: We describe a case of a 69-year-old man who presented with 15% weight loss and general fatigue over the previous 9 months.

In vitro antimicrobial activity of Brazilian medicinal plant extracts against pathogenic microorganisms of interest to dentistry.

This study evaluated the susceptibility of oral pathogenic microorganisms Candida albicans, Streptococcus mutans, Staphylococcus aureus, and Aggregatibacter actinomycetemcomitans to Brazilian medicinal plant extracts of Schinus terebinthifolius (aroeira), Croton campestris (velame), Lafoensia pacari (pacari), Centaurium erythraea (centáurea), Stryphnodendron adstringens (barbatimão), and Anacardium humile (cajuzinho-docerrado), as compared to standardized antimicrobial agents (nystatin, chloramphenicol and tetracycline hydrochloride). Ethanol, hexane and butane fractions from stem barks, rinds, leaves, and/or roots were extracted and tested. Antimicrobial diffusion agar test and MIC were performed according to CLSI.

Efficacy of Brazilian propolis gel for the management of denture stomatitis: a pilot study.

Denture stomatitis presents as a chronic disease in denture-bearing patients, especially under maxillary prosthesis. Despite the existence of a great number of antifungal agents, treatment failure is observed frequently. Propolis, a natural bee product, possesses well-documented antifungal and anti-inflammatory activities.

Sympathetic nerve blocks in mandibular herpes zoster and postherpetic neuralgia.

Sympathetic blocks have been indicated for the diagnosis and treatment of painful neuropathic conditions, such as herpes zoster (HZ) and postherpetic neuralgia (PHN). The purpose of this article is to report a case of mandibular HZ and PHN in an HIV-positive patient, and discuss the efficacy of sympathetic nerve blocks for pain relief and prevention of PHN.
