Fungal infections of the mucous membrane

A clinical review of three potentially severe fungal diseases, which are characterized in many cases by mucosal involvement, is presented. They are paracoccidioidomycosis, histoplasmosis, and mucormycosis. Mucosal involvement for paracoccidioidomycosis and rhinocerebral mucormycosis is frequent. Thus, oral involvement may provide early clue for diagnosis. In paracoccidioidomycosis, the mucosal lesion classically shows superficial ulcers with granular appearance and hemorrhagic points, usually on lips, palate, and jugal mucosa. In mucormycosis, necrosis of the palate followed for purulent discharge is a hallmark of rhinocerebral disease. Treatment with amphotericin B desoxycholate or the new second-generation triazoles is highly efficacious.

Biological properties of medicinal plants: a review of their antimicrobial activity

Plants have been used for thousands of years to flavor and conserve food, to treat health disorders and to prevent diseases including epidemics. The knowledge of their healing properties has been transmitted over the centuries within and among human communities. Active compounds produced during secondary vegetal metabolism are usually responsible for the biological properties of some plant species used throughout the globe for various purposes, including treatment of infectious diseases. Currently, data on the antimicrobial activity of numerous plants, so far considered empirical, have been scientifically confirmed, concomitantly with the increasing number of reports on pathogenic microorganisms resistant to antimicrobials. Products derived from plants may potentially control microbial growth in diverse situations and in the specific case of disease treatment, numerous studies have aimed to describe the chemical composition of these plant antimicrobials and the mechanisms involved in microbial growth inhibition, either separately or associated with conventional antimicrobials. Thus, in the present work, medicinal plants with emphasis on their antimicrobial properties are reviewed.

Carcinoma basalóide escamoso: uma forma rara e agressiva de câncer do esôfago e revisão da literatura

RACIONAL: O carcinoma basalóide escamoso ocorre com maior freqüência no trato aerodigestivo superior e raramente acomete o esôfago. OBJETIVO: Apresentar os aspectos clínico-patológicos e os atributos imunoistoquímicos de um paciente com carcinoma basalóide escamoso do esôfago. RELATO do CASO: Dos 134 pacientes com câncer do esôfago atendidos no Hospital Universitário de Botucatu-Unesp, São Paulo, de 1990 a 1999, somente um paciente (0,74%) apresentou carcinoma basalóide escamoso do esôfago. Tratava-se de paciente masculino, 41 anos, branco, lavrador com disfagia, regurgitação e emagrecimento há três meses. Referia tabagismo e etilismo há muitos anos. O esofagograma e o exame endoscópico revelaram lesão vegetante no terço distal do esôfago. A biópsia demonstrou neoplasia intraepitelial de alto grau associada a blocos de células basalóides que infiltravam o cório da mucosa, caracterizando o carcinoma basalóide escamoso. Os marcadores imunoistoquímicos foram positivos para o antígeno carcinoembriônico e para citoceratinas de alto peso molecular. A tomografia computadorizada revelou múltiplas metástases nos pulmões, fígado, e nódulos linfáticos regionais, documentando a fase avançada de evolução da doença. O tratamento consistiu apenas na realização de gastrostomia. O paciente apresentou queda acentuada do estado geral e evoluiu para óbito com quadro de melena quatro meses após o diagnóstico. CONCLUSÃO: O carcinoma basalóide escamoso é uma forma rara e agressiva de câncer do esôfago e o prognóstico depende do estadiamento da lesão e das condições clínicas do paciente no momento do diagnóstico.

Surgical and clinical management of a patient with Glanzmann thrombasthenia: A case report

A 6-year-old girl with Glanzmann thrombasthenia presented with caries and periapical lesions in the primary mandibular second molars and moderate gingivitis of the maxillary and mandibular anterior teeth. Dental extraction was recommended, and before every surgical intervention, the patient underwent platelet-concentrate transfusion to prevent hemorrhage. Epsilon aminocaproic acid was administered 6 hours before, and 48 hours after every dental procedure to prevent bleeding. In this case, treatment was effective in the prevention of hemorrhagic complications, during the required dental procedures.

Blefarospasmo essencial e espasmo hemifacial: Características dos pacientes, tratamento com toxina botulínica A e revisão da literatura

Purpose: To evaluate the characteristics of the essential blepharospasm and hemifacial spasm patients and the feasible treatment with botulinum toxin. A. Methods: Thirty-four essential blepharospasm or hemifacial spasm patients were evaluated according to gender, ocular complaint, time of disease, treatment outcome and complications. Results: Age median was 63 years and the mean was 61 years, with no difference regarding sex; 66.66% of the patients had hemifacial spasm and 33.33%, essential blepharospasm. Many patients complained of dry eye associated with involuntary spasm. Botulinum toxin A showed a positive outcome in 91.30% of the treated patients and complications observed after treatment were eyelid ptosis (8.33%) and buccal angle deviation (8.33%). Conclusion: Essential blepharospasm and hemifacial spasm occurred in the elderly, of both sexes. Treatment with botulinum toxin A was useful, with very low complication rates.

Tratamento de recessões gengivais múltiplas: uma abordagem mais conservadora

Periodontal therapy has undergone significant changes in recent decades. While in the past the only goal was to restore gingival health, with no concern about the possible consequences of the disease treatment, currently the procedures are performed in a less invasive manner, to maintain aesthetic periodontal results or even recover them. Gingival recession is an alteration frequently found in patients and may be a complaint for causing various complications. For their treatment, several surgical techniques are reported in the literature. The techniques that are more predictable are those that associate a subepithelial connective tissue graft and a coronally repositioned flap. The original technique consists in performing two vertical incisions for an extensive release of the flap and its stabilization in a coronal position. Although this procedure is extremely widespread in the literature, the search for less invasive surgeries without the use of vertical incisions are the current aim of periodontal plastic surgeries, since they present several advantages. The aim of this paper is to demonstrate a case where adjacent, deep and multiple recessions were present resulting in aesthetic problems, which was resolved by a less invasive approach using a surgical technique in envelope and a subepithelial connective tissue graft.
