ABSTRACT

La inyección subcutánea o intramuscular de mercurio elemental, sea accidental o intencional, es una forma poco frecuente de intoxicación. Presentamos el caso de un hombre de 22 años de edad, con antecedentes de rasgos psicóticos y lesiones autolíticas, que se inyectó mercurio elemental en el tejido celular subcutáneo del cuello, tórax y abdomen, tres meses antes de su internación. Las áreas afectadas fueron localizadas mediante el examen físico, radiografías y tomografías. Se realizó el dosaje de mercurio en sangre y orina. Se resecó quirúrgicamente el mercurio de las zonas comprometidas. La detección y remoción precoz del mercurio, mediante cirugía y eventual quelación, es necesaria para prevenir complicaciones a corto y largo plazo.


Accidental or intentional subcutaneous or intramuscular injection of metallic mercury is an uncommon form of intoxication. We present the case of a 22 year-old man, who had psychotic disorders and autoaggressive behavior, with a preceding history of self-injection of mercury into the soft tissues of the neck, thorax and abdomen. Clinical examination, radiographs, and computed tomography showed the affected area. Mercury was measured in blood and urine. The mercury was surgically resected from the affected areas. Early detection and removal of mercury from the body by physical removal or chelation is required to prevent short- and long-term toxicity.

ABSTRACT

O objetivo deste artigo é revisar as características clínicas da tungíase. A Tunga penetrans é a menor das pulgas conhecidas, alcançando 1 milímetro de comprimento quando atinge a fase adulta. Os relatos antigos de surtos de tungíase são escassos em relação aos registros epidemiológicos. O diagnóstico da doença é realizado através da história epidemiológica e dos achados clínicos, aliados ao exame direto com visualização do parasita, após abertura da lesão com agulha estéril. A retirada da pulga é o tratamento preconizado, sendo a profilaxia a melhor alternativa para controlar o parasita. Os profissionais de saúde devem atentar para a importância de se orientar as populações de áreas endêmicas em relação à doença, a fim de reduzir o número de casos e de complicações.


The purpose of this article is to review the clinical features of tungiasis. Tunga penetrans is the smallest known flea, reaching a millimeter in length when fully grown. The earliest accounts of outbreaks of tungiasis are scarce in relation to epidemiological records. The diagnosis is made by history and clinical epidemiological findings, coupled with the direct examination with visualization of the parasite after opening the wound with a sterile needle. The removal of the flea is the recommended treatment, and prophylaxis the best way to control the parasite. Healthcare professionals should be aware as to the importance of educating the public in endemic areas for the disease in order to reduce the number of cases and complications.

ABSTRACT

La reacción liquenoide en la mucosa bucal es una de las formas más frecuentes de las reacciones de hipersensibilidad retardada como respuesta inmune que puede estar relacionada al mercurio u otro componente de la amalgama. La reacción liquenoide es una lesión clínica e histológicamente indistinguible del liquen plano bucal. La única diferencia estriba en que desaparece al retirar el agente causante. Este trabajo tiene como objetivo presentar un caso de lesión liquenoide en mucosa bucal en una mujer de 34 años que solicito asistencia odontológica para diagnóstico y tratamiento de una lesión blanca en la mucosa yugal y encía vestibular derecha adyacente a los dientes 16 y 17 que presentaban restauración de amalgama. Se realizó una biopsia incisional y examen histopatológico teniendo un resultado compatible con el Liquen Plano. Con el consentimiento de la paciente las restauraciones de amalgama fueron substituidas por resina compuesta. Fue verificada la regresión continua de la lesión durante el seguimiento clínico del caso. El diagnóstico definitivo de lesiones liquenoides asociadas a la presencia de restauración de amalgama como factor etiológico es de suma relevancia porque de esta forma se obtiene un tratamiento basado en una intervención simplificada y local, diferente de la compleja actuación que ocurre en tratamientos que envuelven enfermedades auto-inmunes como el liquen plano.


Lichenoid reaction in the buccal mucosa is one of the most frequent forms of delayed hypersensitivity reaction as an immune response, which could be related to mercury or another amalgam component. It is a rare manifestation that is an important differential diagnosis in the group of buccal leucoplakias; and it is the reason of many controversies, particularly regarding lichen planus. The aim of this paper is to present a buccal mucosa lichenoid lesion case in a 34 year-old woman who requested odontologic assistance to be diagnosed and treated for a white lesion, located in the jugal mucosa and right vestibular gum, adjacent to teeth 16 and 17, which had amalgam restorations. An incisional biopsy and a histopatologic exam were made. The result was compatible with Liquen Planus. With the patient's consent the amalgam restorations were replaced with compound resin. A continuous regression of the lesion was verified during the clinical monitoring of the case. The final diagnosis of lichenoid lesions related to amalgam restorations as an etiologic factor is remarkable because by means of this a treatment based on a simplified and local intervention is obtained, which is different from the complicated procedure for treatments that involve auto-immune diseases like lichen planus.

ABSTRACT

Relata-se um caso de um paciente do sexo masculino, de 29 anos de idade, que na tentativa de auto-extermínio injetou 2 ml de mercúrio industrial no antebraço esquerdo. O estudo radiológico mostrou várias esferas metálicas no subcutâneo da fossa olecraniana e ao longo das veias do braço esquerdo, com disseminação para pulmões, coração, fígado, baço e encéfalo.


A case of a male, 29-year-old patient who, in a suicide attempt, has self-administered a 2 ml injection of metallic mercury into his left arm is reported. Radiological studies have shown the presence of several metallic spheres in the subcutaneous tissue of the olecranal fossa and along the veins of the left arm, with dissemination to lungs, heart, liver, spleen and brain.

ABSTRACT

El nombre sífilis proviene del griego siph: cerdo y philus: amor. Recuerda al personaje de una obra, llamado Syphilo, que fue castigado por los dioses a sufrir una terrible enfermedad. Se analizan los datos sobre la sífilis en la antigüedad (que difieren según su fuente). Su mención en la Edad Media, su controversial origen, la ayuda de los paleopatólogos para encontrarlo. Luego de la Revolución Francesa y el inicio de la Edad Contemporánea, el porcentaje de enfermos fue creciendo y se acentuó la segregación de los mismos por la sociedad. Desde el año 1500 hasta principios del siglo XX el tratamiento de la sífilis dependía del mercurio. Tenía una gran variedad de formas de aplicación. La vía tópica: el ungüento gris, en calomelano o tabletas, en inyecciones, en fricciones y fumigaciones en donde el mercurio se introducía en el cuerpo por lo pulmones. Se adjudicó a la madera del guayaco pretendidas características curativas, que no poseía. Los ioduros se utilizaron para el terciarismo. Ehrlich en 1907, patentó el compuesto 606 o Salvarsan y en 1910, el Neo-Salvarsan o Arsfenamina (compuesto 914). Por estos descubrimientos recibió el Premio Nobel. En 1887, Julios Wagner Jauregg sugirió que la fiebre terapéuticamente inducida era útil en el tratamiento de enfermos psicóticos. En 1912 publicó sus satisfactorios resultados al tratar la paresias con una combinación de mercurio-iodo y tuberculina de Koch. En 1917 ingresó a su servicio un enfermo de malaria, con cuya sangre escarificaron la piel palúdica de tres paréticos, en lugar de darle inmediatamente quinina. Por ello fue galardona con el Premio Nobel. Se utilizó luego el bismuto, a partir de 1922, pero posteriormente fue sustituido por las sulfamidas, de aplicación dificultosa. El avance terapéutico más importante ocurrió en 1943, año en que se comenzó a utilizar la penicilina por Mahoney y colaboradores. Luego se confirmó la eficacia de la tetraciclina para los alérgicos a la penicilina. Últimamente se confirmó la eficacia de la azitromicina en dosis de 500mg cada día, durante los 10 días o el régimen de 500mg en días alternos.


The name Syphilis comes from greek language: Siph: Pig and Philus: Love, meaning, in honor of the Sheppard of a story where the Character, Named Syphilo, is punished by the gods to suffer a terrible disease. Data about Syphilis was analized in ancient times (which differ according to the source). Its mention in the middle age, its controversial origin, the help provided from paleopathologists to find it. When the French revolution and the beginning of the contemporary age began, the percentage of sick people grew. The segregation of these is proved by the society. From the year 1500 to the beginnings of the XX century, the treatment of Syphilis depended on mercury. There were a great variety of application methods: topical: the grey ointment, in «calomelanos or tabs¼, in injections, in frictions and fumigations where the mercury was introduced in the body by the lungs. Guayacos wood was named with curative features which it did not posses. The iodides were used for tertiary syphilis. In 1907, Ehrlich formulates the 606 compound or Salvarsan and in 1910 the Neo-Salvarsan or Arsfenamina or compound 914.Due to these discoveries he received the nobel prize. In 1887, Julius Wagner of Jauregg suggested that: the inducted therapeutic fiber was useful in the treatment of the psychosis. In 1912 he published his satisfactory results in treating the paresis with a combination of mercury and iodides and tuberculin of Koch. In 1917 he treated a patient who had malaria and instead of giving him immediately quinine, he made a scarification with his paludic blood the skin of 3 paretic patients. Because of this he was awarded with the nobel prize. Since 1922 bismuth was used, but then it was substituted by the sulphamidas of difficult application. The most important therapeutical advance happened in 1943, year in which penicillin was put in use by Mahoney and col. Later it was confirmed the efficiency of the tetracycline for the penicillin-allergic patients. Lately it has been confirmed the efficiency of the azithromizine in 500 mg dosis each day during 10 days or the regimen of 500 mg in alternate days.

ABSTRACT

Cristas palatinas de fetos de camundongos foram cultivadas in vitro na presença de amálgama que permaneceram na cavidade bucal de pacientes. Verificou-se por meio de análise histológica o efeito tóxico do amálgama sobre o desenvolvimento dos elementos palatinos. Os resultados mostraram a presença de restos epiteliais que alteram o padräo de fechamento do palato. É lícito concluir que o amálgama promove alteraçöes no processo de diferenciaçäo celular
