ABSTRACT Objective: To determine the photodynamic effect of methylene blue (MB) and toluidine blue (TBO) activated with therapeutic laser on Streptococcus mutans and Candida albicans biofilms. Material and methods: Sixty-one biofilm samples were analyzed in brain heart culture media (BHI) for 6 days, the samples were divided into 4 groups and immersed in: experimental group in 0.01% MB and 0.05% TBO, positive control group in 0.12% chlorhexidine gluconate (CHX) and negative control group in 0.9% sodium chloride (NaCl). The MB and TBO samples were irradiated with therapeutic laser with a wavelength of 660 nm, and 9 J/cm2 of power, each enamel block was in post-irradiation culture. The samples were cultured separately for the S. mutans and C. albicans strains, the method used was that of serial dilutions for the quantification of CFU after 5 days of culture. For the analysis, Student's T and Anova of one factor were used. Results: Finding statistical differences between the four experimental groups in microbial growth (ANOVA p<0.05), in the analysis with the positive control group, there were no significant differences between MB versus S. mutans and C. albicans, in contrast to the TBO that showed significant differences (p<0.05). Conclusion: MB and TBO show in laboratory, a decrease in the growth of biofilm strains, TBO showed better effect in reducing the growth of S. mutans and C. albicans.

RESUMEN Objetivo: Determinar el efecto fotodinámico de azul de metileno (MB) y azul de toluidina (TBO) activadas con láser terapéutico sobre biofilms de Streptococcus mutans y Cándida albicans.

Resumo A administração indiscriminada de anti-helmínticos sintéticos, como a ivermectina, contribui para a seleção de subpopulações capazes de resistir ao efeito das drogas. Para entender os mecanismos de resistência à ivermectina em Caenorhabditis elegans, este estudo visou identificar alvos moleculares. Portanto, linhagens de C. elegans sensíveis e resistentes à ivermectina foram utilizadas. Os nematóides coletados foram adicionados ao tampão de extração e macerados em nitrogênio líquido para obtenção das proteínas. As proteínas extraídas foram separadas por peso molecular em SDS-PAGE para verificar sua integridade. Posteriormente, as proteínas de ambas as linhagens foram separadas por eletroforese bidimensional. Os géis foram analisados, os spots relevantes foram excisados e identificados por espectrometria de massa (NanoESI-Q-TOF e MASCOT®), em seguida, analisados em seus termos de GO e STRING®. A expressão aumentada de proteínas associadas à alta atividade metabólica, como as proteínas ATP-2 e ENOL-1, responsáveis pela síntese de ATP, foi observada. Além disso, foram identificadas as proteínas responsáveis pelo controle da função muscular (MLC-1, ACT-1 e PDI-2), sinalização (FAR-1 e FAR-2) e desenvolvimento embrionário (VHA-2). A análise das interações proteicas indicou que a maioria das proteínas identificadas na cepa resistente participa da mesma reação desencadeada pela ivermectina.

Abstract The indiscriminate administration of synthetic anthelmintics such as ivermectin contributes to the selection of subpopulations capable of resisting the drugs’ effects. To understand the mechanisms of ivermectin resistance in Caenorhabditis elegans, this study attempted to identify molecular targets. C. elegans lineages that were sensitive and resistant to ivermectin were used. Collected nematodes were added to an extraction buffer and macerated in liquid nitrogen for protein extraction. The extracted proteins were separated according to molecular weight by SDS-PAGE to verify their integrity. Subsequently, proteins from both lineages were separated using two-dimensional electrophoresis. The gels were analyzed and the relevant spots were excised and identified by mass spectrometry (NanoESI-Q-TOF and MASCOT®) and subsequently assessed by GO enrichment and STRING® analyses. The increased expression of proteins associated with high metabolic activity, such as ATP-2 and ENOL-1, which are responsible for ATP synthesis, was observed. Furthermore, proteins with involvement in mediating muscular function (MLC-1, ACT-1, and PDI-2), signaling (FAR-1 and FAR-2), and embryo development (VHA-2) were identified. Protein interaction analysis indicated that the majority of the identified proteins in the resistant lineages participated in the same reaction triggered by ivermectin.

ABSTRACT Prolactinomas are the most common pituitary adenomas (approximately 40% of cases), and they represent an important cause of hypogonadism and infertility in both sexes. The magnitude of prolactin (PRL) elevation can be useful in determining the etiology of hyperprolactinemia. Indeed, PRL levels > 250 ng/mL are highly suggestive of the presence of a prolactinoma. In contrast, most patients with stalk dysfunction, drug-induced hyperprolactinemia or systemic diseases present with PRL levels < 100 ng/mL. However, exceptions to these rules are not rare. On the other hand, among patients with macroprolactinomas (MACs), artificially low PRL levels may result from the so-called “hook effect”. Patients harboring cystic MACs may also present with a mild PRL elevation. The screening for macroprolactin is mostly indicated for asymptomatic patients and those with apparent idiopathic hyperprolactinemia. Dopamine agonists (DAs) are the treatment of choice for prolactinomas, particularly cabergoline, which is more effective and better tolerated than bromocriptine. After 2 years of successful treatment, DA withdrawal should be considered in all cases of microprolactinomas and in selected cases of MACs. In this publication, the goal of the Neuroendocrinology Department of the Brazilian Society of Endocrinology and Metabolism (SBEM) is to provide a review of the diagnosis and treatment of hyperprolactinemia and prolactinomas, emphasizing controversial issues regarding these topics. This review is based on data published in the literature and the authors' experience.

ABSTRACT The treatment objectives for a patient with Cushing's disease (CD) are remission of hypercortisolism, adequate management of co-morbidities, restoration of the hypothalamic-pituitary-adrenal axis, preservation of fertility and pituitary function, and improvement of visual defects in cases of macroadenomas with suprasellar extension. Transsphenoidal pituitary surgery is the main treatment option for the majority of cases, even in macroadenomas with low probability of remission. In cases of surgical failure, another subsequent pituitary surgery might be indicated in cases with persistent tumor imaging at post surgical magnetic resonance imaging (MRI) and/or pathology analysis of adrenocorticotropic hormone-positive (ACTH+) positive pituitary adenoma in the first procedure. Medical treatment, radiotherapy and adrenalectomy are the other options when transsphenoidal pituitary surgery fails. There are several options of medical treatment, although cabergoline and ketoconazole are the most commonly used alone or in combination. Novel treatments are also addressed in this review. Different therapeutic approaches are frequently needed on an individual basis, both before and, particularly, after surgery, and they should be individualized. The objective of the present review is to provide the necessary information to achieve a more effective treatment for CD. It is recommended that patients with CD be followed at tertiary care centers with experience in treating this condition.

ABSTRACT Clinically nonfunctioning pituitary adenomas (NFPA) are the most common pituitary tumors after prolactinomas. The absence of clinical symptoms of hormonal hypersecretion can contribute to the late diagnosis of the disease. Thus, the majority of patients seek medical attention for signs and symptoms resulting from mass effect, such as neuro-ophthalmologic symptoms and hypopituitarism. Other presentations include pituitary apoplexy or an incidental finding on imaging studies. Mass effect and hypopituitarism impose high morbidity and mortality. However, early diagnosis and effective treatment minimizes morbidity and mortality. In this publication, the goal of the Neuroendocrinology Department of the Brazilian Society of Endocrinology and Metabolism is to provide a review of the diagnosis and treatment of patients with NFPA, emphasizing that the treatment should be performed in reference centers. This review is based on data published in the literature and the authors’ experience. Arch Endocrinol Metab. 2016;60(4):374-90

ABSTRACT Although it is a rare condition, the accurate diagnosis and treatment of Cushing’s disease is important due to its higher morbidity and mortality compared to the general population, which is attributed to cardiovascular diseases, diabetes mellitus and infections. Screening for hypercortisolism is recommended for patients who present multiple and progressive clinical signs and symptoms, especially those who are considered to be more specific to Cushing’s syndrome, abnormal findings relative to age (e.g., spinal osteoporosis and high blood pressure in young patients), weight gain associated with reduced growth rate in the pediatric population and for those with adrenal incidentalomas. Routine screening is not recommended for other groups of patients, such as those with obesity or diabetes mellitus. Magnetic resonance imaging (MRI) of the pituitary, the corticotropin-releasing hormone (CRH) test and the high-dose dexamethasone suppression test are the main tests for the differential diagnosis of ACTH-dependent Cushing’s syndrome. Bilateral and simultaneous petrosal sinus sampling is the gold standard method and is performed when the triad of initial tests is inconclusive, doubtful or conflicting. The aim of this article is to provide information on the early detection and establishment of a proper diagnosis of Cushing’s disease, recommending follow-up of these patients at experienced referral centers.

OBJECTIVE: To assess and compare the sensory processing abilities of children with Attention Deficit/Hyperactivity Disorder (ADHD) and children without disabilities, and to analyze the relationship between sensory processing difficulties and behavioural symptoms presented by children with ADHD. METHOD : Thirty-seven children with ADHD were compared with thirty-seven controls using a translated and adapted version of the "Sensory Profile" answered by the parents/caregivers. For the ADHD group, Sensory Profile scores were correlated to behavioural symptoms assessed using the Child Behaviour Check List (CBCL) and the Behavioural Teacher Rating Scale (EACI-P). The statistical analyses were conducted using the Mann Whitney test and Pearson correlation coefficients. RESULTS : Children with ADHD showed significant impairments compared to the control group in sensory processing and modulation, as well as in behavioural and emotional responses as observed in 11 out of 14 sections and 6 out of 9 factors. Differences in all Sensory Profile response patterns were also observed between the two groups of children. Sensory Profile scores showed a moderately negative correlation with CBCL and EACI-P scores in the ADHD group. CONCLUSION : These results indicate that children with ADHD may present sensory processing impairments, which may contribute to the inappropriate behavioural and learning responses displayed by children with ADHD. It also suggests the importance of understanding the sensory processing difficulties and its possible contribution to the ADHD symptomatology.

A hepatite C é uma doença inflamatória fígado causada por um vírus RNA de fita simples, pertencente ao gênero Hepacivirus e à família Flaviviridae, denominado de vírus da hepatite C. Após infecção inicial 70 a 85% dos pacientes infectados evoluem para hepatite C crônica, com fibrose progressiva. Além das alterações hepáticas específicas, várias manifestações extra-hepáticas têm sido relacionadas à infecção pelo vírus da hepatite C ou às medicações utilizadas no seu tratamento. Nesse trabalho, apresenta-se caso de paciente portador de hepatite C crônica, que manifestou um quadro hanseníase boderline tuberculóide e reação hansênica do tipo I, quatro meses após início do tratamento com interferon peguilado associado à ribavirina.

Hepatitis C is an inflammatory disease of the liver caused by a single-stranded RNA virus belonging to the Hepacivirus genus in the Flaviviridae family, called the hepatitis C virus. After initial infection, 70% to 85% of the patients develop chronic hepatitis C with hepatic fibrosis. In addition to specific liver changes, various extrahepatic manifestations have been associated with the hepatitis C virus infection or with medications used to treat the condition. We report the case of a patient with chronic hepatitis C who presented with the signs and symptoms of borderline tuberculoid leprosy and type 1 reaction four months after the start of treatment with a pegylated interferon/ribavirin combination.

The present study analyzed the effects of age and gender on performance on the Conners' Continuous Performance Test (CCPT II) in a sample of Brazilian adolescents aged 12-17 years. The sample consisted of 480 participants (210 boys) with a mean age of 14.34 years (SD ± 1.61 years) who were representative of the socioeconomic class distribution of the city of São Paulo, Brazil. The participants were prescreened for attention-deficit/hyperactivity disorder. The present results found effects of age and gender that were similar to other Brazilian age groups. Compared with males, female participants presented a lower rate of responding to non-target stimuli (i.e., commission errors), a greater ability to discriminate signals (d'), and fewer impulsive responses (i.e., less perseveration) but longer reaction times (Hit RT and Hit RT Std Error). A significant effect of age was found on RTs (Hit RT, Hit RT Sdt Error, Variability, Hit RT Block Change), commission errors, and perseveration. As age increased, the differences diminished. The present results may be useful for research and clinical studies with Brazilian adolescents.

The objectives of this study were to determine the incidence rate, the cumulative incidence of Postweaning multisystemic wasting syndrome (PMWS) and porcine dermatitis nephropathy syndrome (PDNS), and the frequency of macroscopic and microscopic lesions of PMWS and PDNS in pigs in a farm in the state of Yucatan, Mexico. A group of production consisting of 235 pigs was observed from 4 to 22 weeks of life to determine the number of new cases compatible with the PMWS and PDNS. In addition pigs necropsied on the farm that were discarded and with signs consistent with syndromes studied. 80 pigs were studied, the organs inspected during the necropsy were the lungs, lymphonodes, spleen, liver, tonsils, ileum, kidneys and skin, samples of all organs were obtained for histopathological studies. The results were: 14 pigs with signs consistent with syndromes mentioned, 7 with the PMWS and 7 with the PDNS. The cumulate incidence and incidence rate for both syndromes was 0.06 and 0.0034 respectively. Five pigs died, 3 due to PMWS and 2 due to PDNS. The lethality rate calculated for PMWS and PDNS was of 0.4 and 0.3 respectively. The average time elapsed since the start of the observation period until the pigs sick with the PMWS and PDNS were 13.8 and 16.8 weeks respectively. The principal organ affected were the lymph nodes (100%) where the main macroscopic injury was a lymphadenomegaly with diffuse edema (56%) and the microscopic was a histiocytic lymphadenitis with lymphoid atrophy (64%).

El objetivo fue estimar la incidencia acumulada y verdadera, la tasa de letalidad y la frecuencia de lesiones macroscópicas y microscópicas de los síndromes de emaciación multisistémico postdestete (SEMP) y síndrome dermatitis nefropatía porcina (SDNP), en cerdos de una granja del estado de Yucatán, México. Se seleccionó un lote de producción formado por 235 cerdos, los cuales fueron observados desde la 4 a las 22 semanas de vida para determinar el número de casos nuevos compatibles con SEMP y SDNP. Se practicaron estudios post mortem a todos los cerdos desechados con signos compatibles con SEMP y SDNP. Se realizó el estudio de órganos de 80 cerdos, inspeccionando pulmones, linfonodos, bazo, hígado, tonsilas, íleon, riñones y piel. Se colectaron muestras para histopatología de todos los órganos. Los resultados fueron: 14 cerdos con signos compatibles, 7 con el SEMP y 7 con el SDNP. La incidencia acumulada y verdadera para ambos síndromes fue de 0.06 y 0.0034 respectivamente. Cinco cerdos murieron, 3 con el SEMP y 2 con el SDNP. La tasa de letalidad calculada para el SEMP fue de 0.4 y para el SDNP de 0.3. El tiempo medio de los SEMP y SDNP fue de 13.8 y 16.8 semanas respectivamente. El órgano afectado con mayor frecuencia fueron los linfonodos (100%), la lesión macroscópica más frecuente fue linfadenomegalia con edema difuso (56%) y la microscópica linfadenitis histiocítica con atrofia linfoide (64%).

OBJETIVO: Buscar estudos que avaliem a comorbidade entre transtorno de estresse pós-traumático e transtornos do humor, bem como entre transtorno de estresse pós-traumático e outros transtornos de ansiedade. MÉTODO: Revisamos a base de dados do Medline em busca de estudos publicados em inglês até abril de 2009, com as seguintes palavras-chave: "transtorno de estresse pós-traumático", "TEPT", "transtorno de humor", "transtorno depressivo maior", "depressão maior", "transtorno bipolar", "distimia", "transtorno de ansiedade", "transtorno de ansiedade generalizada", agorafobia", "transtorno obsessivo-compulsivo", "transtorno de pânico", "fobia social" e "comorbidade". RESULTADOS: Depressão maior é uma das condições comórbidas mais frequentes em indivíduos com transtorno de estresse pós-traumático, mas eles também apresentam transtorno bipolar e outros transtornos ansiosos. Essas comorbidades impõem um prejuízo clínico adicional e comprometem a qualidade de vida desses indivíduos. Comportamento suicida em pacientes com transtorno de estresse pós-traumático, com ou sem depressão maior comórbida, é também uma questão relevante, e sintomas depressivos mediam a gravidade da dor em sujeitos com transtorno de estresse pós-traumático e dor crônica. CONCLUSÃO: Os estudos disponíveis sugerem que pacientes com transtorno de estresse pós-traumático têm um risco maior de desenvolver transtornos afetivos e, por outro lado, transtornos afetivos pré-existentes aumentam a propensão ao transtorno de estresse pós-traumático após eventos traumáticos. Além disso, vulnerabilidades genéticas em comum podem ajudar a explicar esse padrão de comorbidades. No entanto, diante dos poucos estudos encontrados, mais trabalhos são necessários para avaliar adequadamente essas comorbidades e suas implicações clínicas e terapêuticas.

OBJECTIVE: To review studies that have evaluated the comorbidity between posttraumatic stress disorder and mood disorders, as well as between posttraumatic stress disorder and other anxiety disorders. METHOD: We searched Medline for studies, published in English through April, 2009, using the following keywords: "posttraumatic stress disorder", "PTSD", "mood disorder", "major depressive disorder", "major depression", "bipolar disorder", "dysthymia", "anxiety disorder", "generalized anxiety disorder", "agoraphobia", "obsessive-compulsive disorder", "panic disorder", "social phobia", and "comorbidity". RESULTS: Major depression is one of the most frequent comorbid conditions in posttraumatic stress disorder individuals, but individuals with posttraumatic stress disorder are also more likely to present with bipolar disorder, other anxiety disorders and suicidal behaviors. These comorbid conditions are associated with greater clinical severity, functional impairment, and impaired quality of life in already compromised individuals with posttraumatic stress disorder. Depression symptoms also mediate the association between posttraumatic stress disorder and severity of pain among patients with chronic pain. CONCLUSION: Available studies suggest that individuals with posttraumatic stress disorder are at increased risk of developing affective disorders compared with trauma-exposed individuals who do not develop posttraumatic stress disorder. Conversely, pre-existing affective disorders increase a person's vulnerability to the posttraumatic stress disorder--inducing effects of traumatic events. Also, common genetic vulnerabilities can help to explain these comorbidity patterns. However, because the studies addressing this issue are few in number, heterogeneous and based on a limited sample, more studies are needed in order to adequately evaluate these comorbidities, as well as their clinical and therapeutic implications.
