ABSTRACT

Abstract Background: Hereditary angioedema can be caused by C1-Inhibitor (C1-INH) deficiency and/or dysfunction (HAE-1/2) or can occur in patients with normal C1-INH (HAE nC1-INH). Methods: The Icatibant Outcome Survey (IOS; NCT01034969) registry monitors the safety and effectiveness of icatibant for treating acute angioedema. Objective: Present findings from Brazilian patients with HAE-1/2 and HAE nC1-INH participating in IOS. Results: 42 patients were enrolled (HAE-1/2, n = 26; HAE nC1-INH, n = 16). Median age at symptom onset was significantly lower with HAE-1/2 vs. HAE nC1-INH (10.0 vs. 16.5y, respectively; p = 0.0105), whereas median age at diagnosis (31.1 vs. 40.9y; p = 0.1276) and the median time between symptom onset and diagnosis (15.0 vs. 23.8y; p = 0.6680) were numerically lower vs. HAEnC1-INH, respectively. One icatibant dose was used for > 95% of HAE attacks. Median (range) time-to-event outcomes were shorter for patients with HAE nC1-INH vs. HAE-1/2, including time Study limitations: This was an observational study without a treatment comparator and that relied on patient recall. Conclusions: Findings demonstrate effectiveness and tolerability of icatibant in Brazilian HAE patients.

ABSTRACT

O pioderma gangrenoso (PG) é definido como uma doença inflamatória e neutrofílica rara, na qual geralmente evolui para ulcerações cutâneas e comprometimento sistêmico, estando associado ao fenômeno de patergia em muitos casos e à doenças sistêmicas subjacentes entre 30-70% dos casos. A etiologia ainda é desconhecida. Manifesta-se através de lesões cutâneas ulceradas e dolorosas com evolução rápida e progressiva, de localização variável. O período entre o início das lesões e o diagnóstico correto costuma ser prolongado. Os achados clínicos e histológicos não são específicos, levando tal patologia a ser um diagnóstico de exclusão. O tratamento varia conforme a gravidade da doença, consistindo em tratamento com corticosteroides e imunossupressores, desde tratamento tópico até uso sistêmico. Não existe nenhum tratamento padronizado ou algoritmo simples para a escolha da terapia. Os autores relatam um caso de Pioderma Gangrenoso em uma mulher de 56 anos que apresentou manifestações clínicas típicas e obteve resposta ao tratamento com prednisona, e apresentam uma revisão de literatura sobre este diagnóstico.


Pyoderma gangrenosum (PG) is defined as an inflammatory and neutrophilic rare disease usually progresses to skin ulcerations and systemic, being associated with pathergy phenomenon in many cases, and systemic diseases in 30-70% of cases. The etiology is still unknown. Manifests itself through ulcerated and painful skin lesions with rapid and progressive evolution, variable location. The period between the onset of lesions and the correct diagnosis is often prolonged. Clinical and histological findings are nonspecific, leading this condition being a diagnosis of exclusion. The treatment varies according to severity of the disease, consisting of treatment with corticosteroids and immunosuppressants, topical and systemic treatment. There is no standard treatment or simple algorithm for choice of therapy. The authors report a case of pyoderma Gangrenosum in a 56-year-old woman who presented typical clinical manifestations and achieved response to treatment with prednisone, and present a literature review about this diagnosis.

ABSTRACT

Para evaluar los efectos cardiorespiratorios y los requerimientos de isofluorano en conejos sometidos a cirugía oftálmica tratados en diferentes momentos con tramadol, fue realizado un estudio prospectivo experimental de tipo ciego en 24 conejos distribuidos aleatoriamente en tres grupos de ocho individuos cada uno: grupo tramadol preoperatorio (Tpre), grupo tramadol transoperatorio (Ttrans) y grupo tramadol postoperatorio (Tpos). Cada animal recibió tres inyecciones intramusculares de igual volumen en los periodos pre, intra y postoperatorio, conteniendo tramadol (4mg/kg) o NaCl 0,9%, de acuerdo al momento indicado para cada grupo. La inducción y mantenimiento anestésico fueron realizados con isofluorano en FiO2 1,0. Una vez estabilizado el plano anestésico, fue iniciado el procedimiento quirúrgico. Se evaluaron: frecuencia cardíaca (FC), presión arterial media (PAM), frecuencia respiratoria (f), presión de CO2 al final de la expiración (EtCO2), saturación parcial de oxihemoglobina (SpO2) y concentración de isofluorano al final de la expiración (EtISO). Las variables fueron medidas después de la estabilización anestésica (m1) y cada 10 min desde el inicio de la cirugía, hasta el final del experimento (m10 a m40). La FC, SpO2, f , EtCO2 y EtISO fueron similares entre grupos durante todo el tiempo. La PAM fue significativamente mayor (p<0,01) durante m1 comparada con el resto del tiempo y el grupo Tpre mostró valores inferiores (p=0,04) de este parámetro durante m1 con relación a los demás grupos. El clorhidrato de tramadol promueve la reducción transitoria de la presión arterial en conejos anestesiados con isofluorano y sometidos a cirugía oftálmica. La administración preoperatoria del fármaco no disminuye el requerimiento anestésico y resulta en hipotensión más pronunciada. Adicionalmente, la anestesia con isofluorano, asociada al reflejo óculo-cardiaco, generan hipotensión arterial, fenómeno que debe tenerse en cuenta durante cirugías oftalmológicas.


To evaluate the cardiorespiratory effects and isoflurane requirements of tramadol applied at different times during ophthalmic surgery, a blind prospective study was made in 24 rabbits, randomly divided into three groups of eight subjects each: pre-operatory tramadol group (Tpre), trans-operatory tramadol group (Ttrans) and post-operatory tramadol group (Tpos), which received three intramuscular injections of equal volume, in the pre, intra and post-operative period, containing tramadol hydrochloride (4 mg/kg) or NaCl 0,9%, according to each group. Anesthetic induction and maintenance was made with isoflurane diluted FiO2 1.0. Once the anesthetic plane was stabilized, surgical procedure was started. Were evaluated heart rate (HR), medium arterial presseure (MAP), respiratory rate (f), end tidal CO2 (EtCO2), Oxihemoglobin saturation (SpO2) and end tidal isoflurane (EtISO). Variables were measured after anesthesia stabilization (m1) and every 10 min after onset of surgery, until the end of experimental protocol (m10 to m40). HR, SpO2, f, EtCO2 and EtISO were similar among groups at all times. MAP were significantly higher (p<0.01) in m1 than in other moments and Tpre group showed lower (p=0.04) values than the other groups at this moment. Tramadol hydrochloride promotes transient reduction of blood pressure in isoflurane anesthetized rabbits subjected to ophthalmic surgery. The preoperative administration of the drug does not reduce the anesthetic requirement and results in a more pronounced hypotension. Additionally, isoflurane anesthesia, associated to oculocardiac reflex generates a hypotension phenomenon that must be taken in to considertation during ophthalmologic surgeries.

ABSTRACT

O objetivo deste estudo transversal foi investigar a prevalência de sobrepeso e adiposidade central (AC) e suas relações com alterações no metabolismo de lipídeos, glicose e níveis pressóricos em uma amostra de 287 indivíduos adultos residentes em uma comunidade rural do Estado de Minas Gerais. Foram realizadas comparações de médias dos indicadores metabólicos: lipoproteínas, glicose e níveis pressóricos, segundo categorias de sobrepeso e AC, usando análise de variância e teste de Tukey. A prevalência de sobrepeso foi de 24,8 por cento (37,4 por cento no sexo feminino; 11,5 por cento no sexo masculino). A AC esteve presente em 28,1 por cento das pessoas (50,3 por cento no sexo feminino; 4,3 por cento no sexo masculino). Indivíduos com AC apresentaram maiores valores médios de pressão arterial (HA), colesterol total, LDL, triglicérides e glicemia de jejum; e menores valores médios de HDL. Foram verificadas associações entre AC e HA, dislipidemia e hiperglicemia. Associações significativas entre sobrepeso e HA, dislipidemia e hiperglicemia também foram evidenciadas. Esses resultados confirmam o potencial efeito das alterações na composição corporal, principalmente em nível central, sobre o metabolismo lipídico e de glicose, e também sobre o aumento dos níveis pressóricos em populações da área rural.


The aim of this cross-sectional study was to verify the prevalence of overweight and central adiposity (CA) in a sample of 287 adult subjects that lived in a rural community of Minas Gerais State. Means lipids, lipoproteins, glucose and blood pressure levels were compared according adiposity categories using One-way ANOVA and Tukey tests. Prevalence of overweight was 24.8 percent (37.4 percent for female; 11.5 percent for male). CA was verified in 28.1 percent of the individuals (50.3 percent for female; 4.3 percent for male). The associations between CA and overweight with the metabolic disorders: arterial hypertension (AH), dyslipidemia and hyperglycemia were estimated. Subjects with CA presented higher mean values of blood pressure, total cholesterol, LDL, triglycerides, fasting glucose, and lower mean values of HDL. CA was associated with AH, dyslipidemia and hyperglycemia. Associations between overweight and AH, dyslipidemia and hyperglycemia were also verified. These results confirm the potential effect of body composition shifting, especially at the abdominal level, on lipids, glucose metabolism and on blood pressure levels in rural populations.

ABSTRACT

As bases moleculares da forma esporadica da doenca de Alzheimer (DA) permanecem ainda desconhecidas. Nos formulamos a hipotese de que, em alguns casos esporadicos de DA, uma mutacao somatica nos genes da proteina precursora amiloide (APP), da presenilina 1 (PS-1) e 2 (STM2) (genes envolvidos na DA forma familiar) em uma celula embrionaria comprometida com o desenvolvimento neuronal, pode resultar em fenotipo da DA. Usando a tecnica de PCR, eletroforese em gel de gradiente desnaturante (DGGE), analise de restricao e sequenciamento direto de DNA, nos analisamos esses genes em 99 tecidos encefalicos de pacientes com DA comprovada histologicamente. Uma amostra de tecido encefalico mostrou uma mutacao no gene PS-1 (His 163 Arg), que mais tarde foi demonstrada ser uma mutacao de celulas germinativas. Nenhuma outra anormalidade de migracao foi demonstrada, em qualquer amostra, nos exons 16 ou 17 do gene APP, nos exons codificadores da PS-1 ou qualquer padrao anormal de digestao pela analise de restricao no gene PS-2...

ABSTRACT

The authors present the results obtained with the development of an experimental model of bronchial fistula and compared different forms of post-pneumonectomy bronchial fistula protection. Forty rats were submitted to left pneumonectomy and bronchial stumps were protected with either pedicled muscle ( N=20 ) or pedicled fat ( N=20 ). The results showed that it was possible to develop a fistula model in 65 por cento of animals and that there was no statistical difference ( p>0.05 ) between the tissues used for bronchial protection

ABSTRACT

La nocardiosis es una infección oportunista localizada o diseminada, que puede comprometer el pulmón, la piel y los tejidos blandos y el sistema nervioso central. Sus agentes etiológicos, pertenecientes al género Nocardia, son bacterias filamentosas que en el examen microscópico directo se tiñen con la coloración de Kinyoun. La disfunción de la inmunidad celular es un factor de riesgo para la adquisición de la enfermedad. Se presenta el caso clínico de un paciente de sexo masculino con nocardiosis pulmonar y enfermedad avanzada debida a HIV-1

ABSTRACT

El Rhodococcus es un bacilo gram+, aerobio, inmóvil, que toma la coloración ácido alcohol resistente en forma inconstante. No esporulado e intracelular, origina una zoonosis que en pacientes VIH+ provoca una infección con localización pulmonar y extrapulmonar. En el 80 por ciento de los casos la forma de presentación primaria es la neumonía cavitada. La inmunodeficiencia del huésped, la localización intracelular y un tratamiento insuficiente se relacionan con la recidiva de la infección. Se presentan 2 casos de infección por este microorganismo, en pacientes VIH+ con localización pulmonar y extrapulmonar y en uno de ellos con carácter recidivante
