ABSTRACT

Histoplasmosis is a systemic mycosis caused by inhalation of Histoplasma capsulatum microconidia. The disease does not normally affect immunocompetent individuals after a single, transient inhalation exposure. However, longer exposure may cause chronic or disseminated acute pulmonary infection. Herein, we report the case of a 24-year-old immunocompetent patient, who presented fever, cough and dyspnea for one month. The chest radiography revealed interstitial infiltrate and diffuse micronodules. The patient reported having had close and prolonged contact with bats. Diagnosis was confirmed by positive double immunodifusion and immunoblotting assays. She was treated with ketoconazole (400 mg) and there was complete resolution of the disease.

ABSTRACT

Ginkgo biloba extract (EGb) is a phytotherapeutic agent used for the treatment of ischemic and neurological disorders. Because the action of this important extract is not fully known, assays using different biological systems need to be performed. Red blood cells (RBC) are labeled with technetium-99m (Tc-99m) and used in nuclear medicine. The labeling depends on a reducing agent, usually stannous chloride (SnCl2). We assessed the effect of different concentrations of EGb on the labeling of blood constituents with Tc-99m, as sodium pertechnetate (3.7 MBq), and on the mobility of a plasmid DNA treated with SnCl2 (1.2 æg/ml) at room temperature. Blood was incubated with EGb before the addition of SnCl2 and Tc-99m. Plasma (P) and RBC were separated and precipitated with trichloroacetic acid, and soluble (SF-P and SF-RBC) and insoluble (IF-P and IF-RBC) fractions were isolated. The plasmid was incubated with Egb, SnCl2 or EGb plus SnCl2 and agarose gel electrophoresis was performed. The gel was stained with ethidium bromide and the DNA bands were visualized by fluorescence in an ultraviolet transilluminator system. EGb decreased the labeling of RBC, IF-P and IF-RBC. The supercoiled form of the plasmid was modified by treatment with SnCl2 and protected by 40 mg/ml EGb. The effect of EGb on the tested systems may be due to its chelating action with the stannous ions and/or pertechnetate or to the capability to generate reactive oxygen species that could oxidize the stannous ion.

ABSTRACT

A obesidade mórbida é reconhecida atualmente como um grande problema para a saúde. Os tratamentos clínicos desta patologia são falhos quando avaliados a longo prazo. Isto levou os cirurgiões a desenvolverem técnicas que resultam em efeitos restritivos ou malabsortivos à ingestão de alimentos. Após alguns meses da cirurgia bariátrica, existe uma perda de peso maciça resultando em grande flacidez da pele do abdômen, mamas, coxas e braços. Neste estudo avalia-mos a técnica de Correa-Iturraspe para o tratamento da região abdominal em dezessete pacientes que apresentaram grande perda ponderal após cirurgia bariátrica.


Morbid obesity is increasingly recognized as a major health concern. Drug treatments of the morbid obese have entirely failed in the long run. These circumstances have constituted incentives for surgeons to develop techniques resulting in malabsorptive or restrictive effects on food intake. Some months after the bariatric surgery there is a massive weight loss and a great skin laxity mainly at the abdomen, breast, tights and arms. In this study we evaluate the Correa-Iturraspe technique to treat the abdominal region in seventeen patiens with massive weigth loss after bariatric surgery.

ABSTRACT

Mastoplastia redutora é um procedimento cirúrgico bastante requisitado por pacientes que apresentam mamas grandes associadas a dores lombres. As grandes hipertrofias impõem técnicas que permitam ressecções associadas ao tratamento da ptose que, na maior parte dos casos, é acentuada. Neste estudo analisamos as técnicas empregadas em 231 casos de mastoplastia redutora, realizados no Serviço de Cirurgia Plástica do Hospital de Clínicas da UFPR no período de 1998 a 2002, das quais 13,8 foram considerados casos de gigantomastia.


Women with big breasts and back pain claim for a reduction mammaplasty. Large volume breast reductions need special atention for the nipple areolar complex migration. In this study we analise the techniques used in 231 reduction mammaplasties performed at “Hospital de Clínicas da Universidade Federal do Parana” from 1998 to 2002. 13,8 of the cases where considered with very large hipertrophies.

ABSTRACT

A neurofibromatose I é a forma clássica da doença, descrita em 1882, por von Recklinghausen, transmitida por herança autossômica dominante. Caracteriza-se pela presença de manchas café-com-leite, nódulos fibromatosos (neurofibromas), nódulos de Lisch na íris e efélides axilares. S.T.N.C, 30 anos, feminina, procurou o serviço de Cirurgia Plástica do Hospital de Clinicas com deformidade crânio-facial centrada em órbita direita, que evoluiu com aumento progressivo da área comprometida associada a amaurose. Ao exame, observou-se importante deformidade hemicraniofacial direita, com lesão neurofibromatosa comprometendo as regiões da fossa temporal superficial, frontal, órbito-palpebral, jugal, labial e mandibular com aspecto de gota gigante multilobulada, tracionando e deformando todas as estruturas da face. Apresentava, ainda, macroqueilia, mordida aberta, ausência de ramo ascendente mandibular direito e paralisia facial direita. Diversas lesões nodulares café-com-leite disseminadas pela superfície cutânea foram encontradas. Os exames complementares realizados, radiografia de face e crânio, tomografia computadorizada e ressonância magnética crânio-facial, demonstraram continuidade da lesão com o tecido cerebral e grande número de fístulas artério-venosa volumosas, denotando associação com deformidade vascular grave. De acordo com estes resultados, foi decidido não submeter a paciente a tratamento cirúrgico, devido ao potencial risco de óbito, bem como a pouca melhora estético funcional a se conseguir com a operação.


In 1882, Von Recklinghausen described neurofibromatosis type I, an autossomal dominant inherited disease, with clinical features of “cafe-au-lait” spots neurofibromas, freckling in the axillary or inguinal regions, optic glioma, Lisch nodules in iris and distinctive osseous lesions. STNC, a 30 year old female, was attended by Plastic Surgery staff at the “Hospital de Clínicas da Universidade Federal do Paraná - Brazil with a craniofacial deformity centred at the right orbit, with progressive regional increase in size and with impaired of visual acuity. Physical findings: prominent hemicraniofacial deformity due to a neurofibroma involving superficial temporal fossa, frontal, orbital, la- bial, jugal and mandibular regions with the aspect of multilobuleted giant drop, tractioning and deforming all the structure of her face. Macrocheilia, mandibular teeth didn’t touch maxillary teeth, absence of ascendant mandibular ramus, right facial palsy and “cafe-au-lait” spots were documented. Image Findings: facial and cranial x-rays, CT and MRI showed that the lesion compromised in continuity with cerebral tissue and the presence of huge arteriovenous fistulas. Management: Due to high risk of death during and/or after the surgery, the patient received clinical and psychological treatment and orientation.

ABSTRACT

Microssomia craniofacial é uma síndrome congênita que afeta as estruturas derivadas do primeiro e segundo arcos branquiais, acometendo mais freqüentemente a mandíbula e a orelha. A perda auditiva na microssomia craniofacial se deve às malformações das estruturas auriculares, no entanto não existem estudos mostrando correlação entre o grau da microssomia craniofacial e o grau de comprometimento auditivo. Foram selecionados aleatoriamente 15 exames audiométricos em pacientes portadores de microssomia craniofacial entre 2001 e 2002. Todos os exames foram realizados com o aparelho Midimate 602 e Audiotest 227. Foram avaliados 15 pacientes, 8 mulheres e 7 homens, com média de idade de 8,5 anos, sendo 1 caso bilateral. Quatorze pacientes apresentavam microtia, e destes, 11 não apresentavam conduto auditivo externo. O tipo de perda auditiva mais freqüente foi a condutiva, em 12 casos. A média do déficit auditivo foi de 63,76dB. A malformação dos componentes auditivos é frequente e o acompanhamento com exames audiométricos pode detectar precocemente déficits auditivos levando a uma melhor reabilitação. Com a realização de exames audiométricos na avaliação de pacientes portadores de microssomia craniofacial propicia-se melhor desenvolvimento psicossocial destes pacientes.


Craniofacial microsomia is a congenital syndrome affecting the structures derived from first and second branchial archs. Most commonly the ear and jaws are involved. Hearing loss in this syndrome is due to auricular structures malformation, however there is not proved correlation between the severity of malformation and hearing loss. Fifteen audiometry performed in 2001 and 2002 were randomly selected between patients with craniofacial microsomia. All tests were performed with Midimate 602 e Audiotest 227 device. Fifteen patients were evaluated, 8 women and 7 men, the mean age was 8,5 years and one case was bilateral. Fourteen patients had microtia and eleven external auditory canal agenesia. The most common hearing loss was conductive. Hearing deficit mean was 63,76 dB. Auditive components malformation is frequent is this syndrome and audiometry evaluation may improve rehabilitation in patients in which hearing loss in early detected. Audiometry should be employed in craniofacial microsomia initial evaluation leading to better psicosocial development.

ABSTRACT

A Microssomia Craniofacial é deformidade com grande variedade de apresentações clínicas. Tratamos 105 casos em 7 anos, entre 1996 a 2002. Os casos foram revisados enfocando as suas alterações anatômicas. A idade de início do tratamento foi entre 0 e 5 anos em 39, 6 a 10 anos em 27,6 e após 10 anos em 33,4. Em 44,8 o lado comprometido foi o direito, o esquerdo em 38 e bilateral em 17,2. O pavilhão auricular era normal em 10; microtia correspondeu a 81 das deformidades auriculares, anotia a 12,6, orelha constricta a 6,3, question ear a 4,2, duplicidade a 4,2 e ausência do lóbulo a 1. Em 65,7 dos pacientes o meato acústico estava ausente e em 2,8 havia atresia. De acordo com a classificação de Pruzanski, foram de 35,2 as alterações mandibulares de Grau I, 21,9 de Grau IIA, 16,1 de Grau IIB e 3,8 de Grau III. Em 22,8 a mandíbula apresentava-se normal. Paralisia facial foi encontrada em 11,4 e macrostomia em 22,8. Em 10 dos pacientes apresentavam alterações oftalmológicas, dentre elas, 3 casos dermóide epibulbar. Em 21,9 foram identificadas outras deformidades faciais, com 5 casos de hipoplasia de partes moles, 9 de fissuras lábiopalatais e 2 de atrofia do masséter.


Hemifacial Microsomia is a deformity with a great variety of clinical feature. We have been treating 105 cases in last 7 years. The revision is focusing over the anatomic disorders. The patients looked for treatment between 0 – 5 y.old in 39, 5 – 10 in 27,6 and after 10 years old in 33,4. In 44,8 of the patients the deformities were at right side and 38 in the left, and in 17,2 was bilateral. Normal ear was seen in 10. In patients with auricular deformities microtia was seen in 81, anotia 12,6, lop and cup ear in 6,3, question ear in 4,2, duplicity in 4,2 and absence of lobulus in 1. In 65,7 of the patients the meatus was absence and 2,8 with atresic meatus. According to classification of Pruzanski, 35,2 of mandibular deformities were grade I, 21,9 grade IIA, 16,1 grade IIB and 3,8 grade III. Mandible was normal in 22,8. Facial palsy was found in 11,4, and macrostomy in 22,8. Around 10 of our patients had ocular deformities, and 3 of them had epibulbar dermoids. Others facial malformation occurred in 21,9, included: soft tissue hipoplasia in 5 cases, cleft lip and/or palate in 9 cases, and masseter atrophy in 2 cases .

ABSTRACT

Mamaplastia de aumento é cirurgia amplamente realizada em todo o mundo, com tendência atual de redução de cicatrizes. Em casos onde a aréola é grande e não há ptose mamária, pode-se utilizar a via transareolomamilar, com redução da aréola e cicatiz na base do mamilo. Apresentamos o relato de um caso de inclusão de prótese mamária com redução do complexo aréolo-mamilar e cicatriz perimamilarn.


Augmentation mammaplasty is a very common surgery performed around the world. This paper presents a case report where we used a surgical access positioning the scar around the nipple.
