ABSTRACT
SUMMARY OBJECTIVE: The aim of this study was to evaluate the impact of study methodology and evaluation type on the selection of studies during the presentation of scientific events. METHODS: A prospective, observational, transversal approach was applied to a cohort of studies that were submitted for presentation at the 2021 Brazilian Breast Cancer Symposium. Three forms of criteria (CR) were presented. CR1 was based on six criteria (method, ethics, design, originality, promotion, and social contribution); CR2 graded the studies from 0 to 10 for each study, and CR3 was based on five criteria (presentation, method, originality, scientific knowledge, and social contribution). To evaluate the item correlation, Cronbach's alpha and factorial analysis were performed. For the evaluation of differences between the tests, we used the Kruskal-Wallis and post-hoc Dunn tests. To determine the differences in the study classifications, we used the Friedman test and Namenyi's all-pairs comparisons. RESULTS: A total of 122 studies were evaluated. There was also a good correlation with the items concerning criterion 1 (α=0.730) and 3 (α=0.937). Evaluating CR1 methodology, study design and social contribution (p=0.741) represents the main factor and CR3 methodology, and the scientific contribution (p=0.994) represents the main factor. The Kruskal-Wallis test showed differences in the results (p<0.001) for all the criteria that were used [CR1-CR2 (p<0.001), CR1-CR3 (p<0.001), and CR2-CR3 (p=0.004)]. The Friedman test showed differences in the ranking of the studies (p<0.001) for all studies (p<0.01). CONCLUSION: Methodologies that use multiple criteria show good correlation and should be taken into account when ranking the best studies.
ABSTRACT
Diagnosis in psychiatry is a thorough and potentially artificial process. In this letter, we discuss this diagnostic process in the context of a young patient who underwent nipple-sparing mastectomy after falsifying a breast biopsy report revealing invasive ductal carcinoma. The secondary pathology revision was also forged by the patient and confirmed the diagnosis. The patient was summoned by the Service's board and admitted the falsification of breast cancer reports. After evaluation at the Psychiatric Service, changes in vital mood, psychosis, delusional activity and obsessive-compulsive symptoms were ruled out. In view of the growing demand for prophylactic mastectomy observed worldwide, similar cases may become more frequent.
ABSTRACT
Objective: To verify data-coding accuracy for ductal carcinoma in situ at the Goiânia population-based cancer registry in the Brazilian state of Goiás. Methods: Ecological time series analysis of cases coded as ductal carcinoma in situ in the state cancer database (ONCOSIS), considering data from the Goiânia population-based cancer registry, from 1994 to 2010. Results: Of 376 cases originally coded as ductal carcinoma in situ, 115 were excluded following a review of the pathology reports. These exclusions referred to cases of lobular carcinoma in situ (n=21), Paget's disease (n=4), invasive carcinoma (n=08), ductal carcinoma in situ associated with invasive carcinoma (n=14), microinvasive carcinoma (n=21), records on non-residents in Goiânia, and duplicated data (n=46). Conclusion: Many cases needed recoding and, as a consequence, altered the initial database. Standardizing pathology reports and training data collection staff are crucial steps to avoid omissions and errors when transcribing cases of ductal carcinoma in situ in a population-based cancer registry database.
Objetivo: Verificar a acurácia da codificação dos dados de carcinoma ductal in situ dentro do Registro de Câncer de Base Populacional de Goiânia, Goiás - Brasil. Métodos: Estudo ecológico de série temporal de casos codificados como carcinoma in situ da mama, pelo programa (ONCOSIS) do Registro de Câncer de Base Populacional de Goiânia, entre 1994 e 2010. Posteriormente realizouse busca individual dos laudos histopatológicos de CDIS. Resultados: De 376 casos de CDIS, foram excluídos 115 casos após a revisão dos laudos anatomopatológicosas. As exclusões referem-se a carcinoma lobular in situ (21), Doença de Paget (4), carcinoma invasor (08); CDIS associado a carcinoma invasor (14); microinvasor (21), pacientes com endereço fora de Goiânia e dados duplicados (46). Conclusão: Há um grande número de casos que precisam ser recodificados, alterando o banco inicial. A padronização de laudos e o treinamento dos coletadores são etapas importantes para que não haja informações desconhecidas ao transcrever o CDIS para as fichas do RCBP.
ABSTRACT
ABSTRACT Background: Chagasic colopathy is the second most common digestive manifestation, and constipation is the main symptom. The absence of the Rectoanal Inhibitory Reflex plays an important role in constipation and anal manometry is crucial for appropriate evaluation. Purpose: Evaluate anal manometry findings (mainly Rectoanal Inhibitory Reflex) in Chagasic patients with chronic constipation, with and without megacolon and correlate these findings with clinical and demographic data. Methods: Cross-sectional study of patients with chronic constipation who underwent Chagasic serologic test, barium enema, and anal manometry. The absence of Rectoanal Inhibitory Reflex was evaluated using the mid-P Exact Test. Results: 64 Patients were included: 23 Chagasic patients with megacolon/megarectum (G1), 21 Chagasic patients without megacolon/megarectum (G2) and 20 non-Chagasic patients without megacolon/megarectum (G3). Chagasic patients with megacolon had a higher incidence of fecaloma (39%) compared to the other two groups (9.5% and 10% for G2 and G3, respectively, p = 0.03). Rectal capacity on manometry was statically higher for G1 patients. Rectoanal Inhibitory Reflex was absent in 91.3% of patients in G1, 47.29% in G2 and present in all patients in G3. There was a significant difference in the absence of the Rectoanal Inhibitory Reflex when comparing the groups (G1 vs. G2: p = 0.002, G1 vs. G3: p < 0.001, G2 vs. G3: p < 0.001). Conclusion: The absence of RAIR confirms the diagnosis of Chagasic colopathy and endorses surgical treatment whenever clinical treatment fails. The presence of the RAIR in patients with positive serology for Chagas disease without megacolon/megarectum might not be due chagasic colopathy and other causes should be considered.
RESUMO Fundamento: A colopatia chagásica é a segunda manifestação digestiva mais comum e a constipação é o principal sintoma. A ausência do Reflexo Inibitório Retoanal desempenha um papel importante na constipação e a manometria anal é crucial para avaliação adequada. Objetivo: Avaliar os achados da manometria anal (principalmente o Reflexo Inibitório Retoanal) em pacientes chagásicos com constipação crônica, com e sem megacólon, e correlacionar esses achados com dados clínicos e demográficos.Métodos: Estudo transversal de pacientes com constipação crônica submetidos ao teste sorológico para doença de chagas, enema de bário e manometria anal. A ausência de Reflexo Inibitório Retoanal foi avaliada por meio do Teste Exato de Ponto Médio. Resultados: Foram incluídos 64 pacientes: 23 chagásicos com megacólon/megarreto (G1), 21 chagásicos sem megacólon/megarreto (G2) e 20 não chagásicos sem megacólon/megarreto (G3). Os pacientes chagásicos com megacólon apresentaram maior incidência de fecaloma (39%) em comparação aos outros dois grupos (9,5% e 10% para G2 e G3, respectivamente, p = 0,03). A capacidade retal na manometria foi estatisticamente maior nos pacientes do G1. O Reflexo Inibitório Retoanal estava ausente em 91,3% dos pacientes do G1, em 47,29% no G2 e presente em todos os pacientes do G3. Houve diferença significativa na ausência do Reflexo Inibitório Retoanal quando comparados os grupos (G1 vs. G2: p = 0,002, G1 vs. G3: p < 0,001, G2 vs. G3: p < 0,001). Conclusão: A ausência de RIRA confirma o diagnóstico de colopatia chagásica e endossa o tratamento cirúrgico sempre que o tratamento clínico falhar. A presença de RIRA em pacientes com sorologia positiva para doença de Chagas, sem megacólon/megarreto, pode não ser devida à colopatia chagásica e outras causas devem ser consideradas.

Abstract Objective To estimate the cytological and colposcopic performances for the diagnosis of cervical neoplasias. Methods Cross-sectional retrospective study with data from patients' charts. The participants underwent colposcopy, guided biopsies, and excision when needed. The cytological and colposcopic categorization followed the Bethesda System and the international colposcopic terminologies. The cytology and colposcopy performances were evaluated by sensitivity (SE), specificity (SP), positive predictive value (PPV), and negative predictive value (NPV) analyses with 95% confidence interval (95% CI). Results From 1,571 participants, a total of 1,154 (73.4%) were diagnosed with cervical squamous intraepithelial neoplasia grade 2 or worse (CIN 2+), 114 (7.2%) with adenocarcinoma in situ or worse (AIS+), 615 (39.2%) presented atypical squamous cells, cannot exclude high-grade squamous intraepithelial lesion or worse (ASC-H+) cytology, and 934 (59.4%) presented major or suspicious for invasion colposcopic abnormalities. The SE, SP, PPV, and NPV of ASC-H+ for diagnoses of CIN 2+ and AIS+ were, respectively: 44% (95% CI: 41-47) and 72% (95% CI: 67-76), 79% (95% CI: 77-81) and 79% (95% CI: 75-83), 88% (95% CI: 87-90) and 55% (95% CI: 50-60), and 28% (95% CI: 26-31) and 88% (95% CI: 85-91). The SE, SP, PPV, and NPV of major or suspicious for invasion colposcopic abnormalities for diagnoses of CIN 2+ and AIS+were, respectively: 62% (95% CI: 60-65) and 86% (95% CI: 83-89), 59% (95% CI: 57-62) and 59% (95% CI: 55-64), 85% (95% CI: 83-87) and 44% (95% CI: 40-49), and 29% (95% CI: 27-32) and 92% (95% CI: 89-94). Conclusion The SE analyses results of ASC-H+ and major or suspicious for invasion colposcopic abnormalities were higher for diagnoses of glandular neoplasias. These results confirm the role of cytology in identifying women at risk who will have their final diagnoses settled by colposcopy and histology.
Resumo Objetivo Estimar o desempenho da citologia e colposcopia no diagnóstico das neoplasias cervicais. Métodos Estudo retrospectivo de corte transversal com dados coletados em prontuários. Foram incluídas participantes que foram submetidas a colposcopia, biópsia e excisão quando necessário. A categorização da citologia e da colposcopia seguiram a terminologia de Bethesda e a classificação colposcópica internacional. Os desempenhos da citologia e colposcopia foram avaliados por análises de sensibilidade (S), especificidade (E), valor preditivo positivo (VPP) e valor preditivo negativo (VPN), com intervalos de confiança de 95% (IC 95%). Resultados Das 1.571 participantes, um total de 1.154 (73,4%) foram diagnosticadas com neoplasia intraepitelial escamosa cervical de grau 2 ou mais grave (NIC 2+), 114 (7,2%) com adenocarcinoma in situ ou mais grave (AIS+), 615 (39,2%) apresentaram células escamosas atípicas de significado indeterminado, quando não se pode excluir lesão intraepitelial de alto grau ou mais grave (ASC-H+) e 934 (59,4%) tiveram achados colposcópicos maiores ou suspeitos de invasão. Os valores de S, E, VPP e VPN das ASCH + para o diagnóstico de NIC 2+ e AIS+ foram, respectivamente: 44% (IC 95%: 41-47) e 72% (IC 95%: 67-76), 79% (IC 95%: 77-81) e 79% (IC 95%: 75-83), 88% (IC 95%: 87-90) e 55% (IC 95%: 50-60) e 28% (IC 95%: 26-31) e 88% (IC 95%: 85-91). Os valores de S, E, VPP e VPN dos achados colposcópicos maiores ou suspeitos de invasão para o diagnóstico de NIC 2+ e AIS+ foram, respectivamente: 62% (IC 95%: 60-65) e 86% (IC 95%: 83-89), 59% (IC 95%: 57-62) e 59% (IC 95%: 55-64), 85% (IC 95%: 83-87) e 44% (IC 95%: 40-49) e 29% (IC 95%: 27-32) e 92% (IC 95%: 89-94). Conclusão Os resultados das análises de S de ASC-H+ e achados colposcópicos maiores ou suspeitos de invasão foram mais elevados para o diagnóstico das neoplasias glandulares. Esses resultados confirmam o papel da citologia na identificação de mulheres em risco que terão seus diagnósticos definidos por colposcopia e histologia.

Ductal carcinoma in situ (DCIS) has been detected more frequently in the last decades using the mammographic screening. The objective of the present study was to review the epidemiological aspects of DCIS. A bibliographic narrative review was carried out focusing on the following aspects: the epidemiology of DCIS to discuss subtypes; natural history; screening; and survival. It was possible to verify that the DCIS is currently considered a precursor lesion of breast cancer, presenting a considerable and uneven increased incidence between developed and developing countries, probably due to the inclusion of mammographic screening programs. There are controversies regarding the benefit or not of its detection, diagnosis, treatment and survival of patients with DCIS. It is concluded that the considerable increase in the incidence of DCIS raises an important discussion about the real need for its diagnosis as well as its real biological significance
carcinoma ductal in situ (CDIS) tem sido detectado com maior frequência nas últimas décadas a partir do rastreamento mamográfico. O objetivo do presente estudo foi revisar os aspectos epidemiológicos do CDIS. Foi realizada uma revisão bibliográfica narrativa enfocando os aspectos do CDIS: epidemiologia, para discussão a respeito dos subtipos; história natural; rastreamento; e sobrevida. Foi possível verificar que o CDIS é atualmente considerado como uma lesão precursora do câncer de mama e apresenta aumento considerável e desigual em sua incidência entre países desenvolvidos e em desenvolvimento, devido, provavelmente, à inclusão dos programas de rastreamento mamográfico. Há controversas quanto ao benefício ou não da detecção, do diagnóstico, do tratamento e da sobrevida de pacientes que apresentam o CDIS. Conclui-se que o aumento considerável da incidência do CDIS levanta importante discussão sobre a necessidade real de seu diagnóstico, bem como do seu real significado biológico
ABSTRACT
OBJECTIVE: This randomized clinical trial evaluated the possibility of not draining the axilla following axillary dissection. METHODS: The study included 240 breast cancer patients who underwent axillary dissection as part of conservative treatment. The patients were divided into two groups depending on whether or not they were subjected to axillary drainage. ClinicalTrials.gov: NCT01267552. RESULTS: The median volume of fluid aspirated was significantly lower in the axillary drainage group (0.00 ml; 0.00 - 270.00) compared to the no drain group (522.50 ml; 130.00 - 1148.75). The median number of aspirations performed during conservative breast cancer treatment was significantly lower in the drainage group (0.5; 0.0 - 4.0) compared to the no drain group (5.0; 3.0 - 7.0). The total volume of serous fluid produced (the volume of fluid obtained from drainage added to the volume of aspirated fluid) was similar in the two groups. Regarding complications, two cases (2.4%) of wound dehiscence occurred in the drainage group compared to 13 cases (13.5%) in the group in which drainage was not performed, with this difference being statistically significant. Rates of infection, necrosis and hematoma were similar in both groups. CONCLUSION: Safety rates were similar in both study groups; hence, axillary dissection can feasibly be performed without drainage. However, more needle aspirations could be required, and there could be more cases of wound dehiscence in patients who do not undergo auxiliary drainage.

Summary Introduction: Methylene blue is more widely available and less expensive than patent blue, with an apparently lower risk of anaphylaxis. Objective: The two dyes were compared regarding detection of the sentinel lymph node (SLN). Method: A prospective, randomized trial involved 142 patients with invasive breast carcinoma. Sixty-nine (49.3%) assigned to patent blue (group A) and 71 (50.70%) to methylene blue (group B). Thirty-five patients (25.0%) were clinical stage III or IV; 55 (38.7%) had axillary lymph nodes affected; and 69 (49.3%) underwent neoadjuvant chemotherapy. Two patients were excluded because the dye type was not recorded. Results: Patients and tumor characteristics were similar in both groups. SLNs were identified in 47 women (68.1%) in group A and 43 (60.6%) in group B (p=0.35). SLNs were affected in 22 cases (51.2%) in group A and 21 (48.8%) in group B (p=0.62). The SLN was the only node affected in 12 cases (54.5%) in group A and six (33.3%) in group B (p=0.18). The time and degree of difficulty involved in identifying the SLN were similar in both groups. There were no complications or allergies. Conclusion: Methylene blue performed as well as patent blue in identifying the SLN in breast cancer patients.
Resumo Introdução: O azul de metileno é mais facilmente encontrado para comercialização e a um preço menor que o azul patente. Parece ainda haver menor risco de anafilaxia. Objetivo: Comparar a taxa de detecção do linfonodo sentinela com o azul patente e com o azul de metileno. Método: Foram incluídas, de forma randomizada e prospectiva, 142 pacientes com diagnóstico de carcinoma mamário invasor, que consentiram em participar livremente do estudo. Foram injetados 2 mL de azul patente (grupo A) em 69 (49,3%) mulheres e de azul de metileno (grupo B) em 71 (50,70%), em localização periareolar ou peritumoral, seguido de 5 minutos de massagem. Trinta e cinco (25,0%) apresentavam estadiamento clínico 3 ou 4, e 55 (38,7%) apresentavam a axila clinicamente comprometida. Sessenta e nove (49,3%) fizeram quimioterapia neoadjuvante. Duas pacientes não tinham anotação do corante utilizado e foram excluídas. Resultados: Os dois grupos apresentaram características das pacientes e dos tumores semelhantes. Foram detectados linfonodos sentinela em 47 (68,1%) mulheres no grupo A e em 43 (60,6%) no grupo B (p=0,35). Havia linfonodos sentinela comprometidos em 22 (51,2%) casos no grupo A e em 21 (48,8%) casos no grupo B (p=0,62). O linfonodo sentinela foi o único gânglio comprometido em 12 (54,5%) casos no grupo A e em seis (33,3%) casos no grupo B (p=0,18). O tempo e o grau de dificuldade para identificação do linfonodo sentinela foram semelhantes nos dois grupos. Não houve relato de complicações ou de alergia em nenhum dos grupos. Conclusão: A utilização do azul de metileno para a identificação do linfonodo sentinela em pacientes com câncer de mama apresenta resultados semelhantes aos do azul patente.

ABSTRACT PURPOSE: To investigate if the association of fat grafts and platelet-rich plasma (PRP) improves graft viability in female rats. METHODS: This is an experimental, randomized and blinded study, which involved 47 rats. Fat was harvested from the inguinal region and grafted to the cranial region. The experimental group consisted of PRP-enriched fat grafts (n=22) whilst the control group consisted of fat graft only (n=25). After a 100-day period, the animals were euthanised and the fat grafts were analyzed using scores from 0 (absent) to 4 (abundant), in optical microscopy by two independent and blinded pathologists. RESULTS: Regarding fat graft cell viability, the PRP group scored moderate/abundant in 63% of cases and the fat graft only group scored absent/slight in 72% of cases (p=0.03). The PRP group also presented lower fat necrosis scores when compared to the fat graft only group (p=0.03). Tumors (dermoid cysts) within the fat grafts were observed in three animals in which the grafts were mixed with PRP. CONCLUSION: Platelet-rich plasma improves the viability and integration of fat grafts in rats, but more studies are needed to fully understand the exact mechanisms that lead to this improvement and assess the safety of the method for use in humans.

Abstract Hypersensitivity pneumonitis is a diffuse interstitial and granulomatous lung disease caused by the inhalation of any one of a number of antigens. The objective of this study was to illustrate the spectrum of abnormalities in high-resolution computed tomography and histopathological findings related to hypersensitivity pneumonitis. We retrospectively evaluated patients who had been diagnosed with hypersensitivity pneumonitis (on the basis of clinical-radiological or clinical-radiological-pathological correlations) and had undergone lung biopsy. Hypersensitivity pneumonitis is clinically divided into acute, subacute, and chronic forms; high-resolution computed tomography findings correlate with the time of exposure; and the two occasionally overlap. In the subacute form, centrilobular micronodules, ground-glass opacities, and air trapping are characteristic high-resolution computed tomography findings, whereas histopathology shows lymphocytic inflammatory infiltrates, bronchiolitis, variable degrees of organizing pneumonia, and giant cells. In the chronic form, high-resolution computed tomography shows traction bronchiectasis, honeycombing, and lung fibrosis, the last also being seen in the biopsy sample. A definitive diagnosis of hypersensitivity pneumonitis can be made only through a multidisciplinary approach, by correlating clinical findings, exposure history, high-resolution computed tomography findings, and lung biopsy findings.
Resumo A pneumonite por hipersensibilidade é uma doença intersticial difusa, granulomatosa e de natureza inalatória, com inúmeros antígenos orgânicos e inorgânicos implicados. Nosso objetivo é ilustrar o espectro de anormalidades na tomografia de alta resolução do tórax e achados histopatológicos. Foram avaliadas, retrospectivamente, tomografias de alta resolução do tórax de pacientes com diagnóstico de pneumonite por hipersensibilidade estabelecido em correlação clínico-radiológica e clínico-radiológico-patológica em pacientes em que a biópsia esteve disponível. A pneumonite por hipersensibilidade é dividida, do ponto de vista clínico e didático, em aguda, subaguda e crônica, e as manifestações tomográficas da tomografia de alta resolução do tórax correlacionam-se com o tempo da evolução da doença, e por vezes se superpõem. Micronódulos centrolobulares, vidro fosco e aprisionamento aéreo são características tomográficas na manifestação subaguda, em que, histopatologicamente, se observam infiltrado inflamatório linfocítico, bronquiolite, graus variáveis de pneumonia em organização e células gigantes. Na fase crônica, a tomografia demonstra sinais de fibrose com bronquiolectasias de tração e eventualmente faveolamento, com predomínio superior, sendo observados também sinais de fibrose no estudo histopatológico. A abordagem multidisciplinar é definitiva no diagnóstico, que é realizado correlacionando-se as características clínicas, nexo causal de exposição, achados tomográficos e aspectos histopatológicos.
ABSTRACT
Objetivo: Determinar a prevalência de doença de Paget da mama (DPM) entre os casos de carcinomas ductais diagnosticados em um centro universitário, entre 2003 e 2007, descrever as características clínicas e analisar a sobrevida desses casos. Métodos: Estudo de coorte retrospectiva, por meio da revisão de prontuários médicos. Foi realizada análise de frequência para todas as variáveis e utilizada curva de Kaplan-Meier para a representação da sobrevida global. Resultados: De 278 casos de carcinomas ductais de mama, houve 14 casos de DPM, determinando prevalência de 5,0%. Um caso foi excluído da análise por apresentar dados incompletos. A média de idade ao diagnóstico foi de 57,1 (±11,2) anos. Dos casos analisados, 11 (84,6%) apresentavam tumor palpável, e 9 (69,3%), lesão do complexo aréolo-papilar (CAP). Apenas um caso não foi submetido à mastectomia, por óbito durante quimioterapia neoadjuvante. Radioterapia foi realizada em 6 casos (46,2%), quimioterapia, em 11 casos (84,6%), e endocrinoterapia, em 6 casos (46,2%). A imunoistoquímica identificou 5 casos (38,5%) com expressão de receptores hormonais e 12 casos (92,3%) com superexpressão de HER2. A sobrevida global das pacientes foi de 61,5 (±13,4) meses e não houve recidiva local após um tempo médio de seguimento de 75,8 meses. Conclusão: Observou-se prevalência de DPM associada a carcinomas invasores com estádio clínico avançado, o que possivelmente ocasionou sobrevida global inferior à observada em estudos prévios para a região.
Objective: To determine the prevalence of Paget's disease of the breast (PD) among cases of ductal carcinomas diagnosed in a university hospital between 2003 and 2007; describe clinical characteristics and analyze the survival of these cases. Methods: Retrospective cohort study, by reviewing medical records. Frequency analysis was performed for all variables and used Kaplan-Meier curve for the representation of overall survival. Results: In 278 cases of breast ductal carcinoma, 14 cases were PD determining prevalence of 5.0%. A case was excluded from analysis because of incomplete data. The mean age at diagnosis was 57.1 (±11.2) years. Of the cases analyzed, 11 (84.6%) had palpable tumor and 9 (69.3%) presented lesion of the nipple-areola complex. Only one case was not submitted to mastectomy because she died during neoadjuvant chemotherapy. Radiotherapy was performed in six cases (46.2%); chemotherapy in eleven cases (84.6%); endocrinoterapia in six cases (46.2%). Immunohistochemistry identified five cases (38.5%) with expression of hormone receptors and twelve patients (92.3%) with overexpression of HER2. The overall survival of patients was 61.5 (±13.4) months, and there was no local recurrence after a mean follow-up of 75.8 months. Conclusion: There was a prevalence of Paget's disease of the breast associated with invasive carcinomas with advanced clinical stages; which possibly resulted in overall survival rate lower than that observed in other studies for the region.
ABSTRACT
Introdução: Os homens transexuais (TX) fazem uso de androgênios por uso prolongado, eventualmente, de forma indiscriminada. Sabe-se que os androgênios endógenos têm efeito inibitório no tecido mamário, enquanto a testosterona exógena pode exercer efeito indireto na mama ao ser convertida em estrogênio pela aromatização, colaborando, assim, para aumentar o risco de câncer de mama. Objetivos: Avaliar a expressão dos receptores de estrogênio, progesterona e Ki-67 no tecido mamário de transexuais feminino para masculino, mulheres biológicas e homens com ginecomastia. Material: Estudo de série de casos que incluiu 17 pacientes, sendo 5 transexuais submetidos à adenomastectomia, que fazem acompanhamento no Ambulatório de Transexualismo do Hospital das Clínicas da Universidade Federal de Goiás (UFG), 4 mulheres que realizaram mamoplastia redutora e 8 homens biológicos submetidos à cirurgia para correção de ginecomastia. Os espécimes cirúrgicos foram avaliados por imuno-histoquímica. Resultados: Os transexuais apresentaram menor taxa de reatividade dos receptores de estrogênio e progesterona, quando comparados com mulheres e homens biológicos, e todos os pacientes em uso de androgênio tiveram expressão do Ki-67 ≤1%. A maior taxa de expressão do Ki-67 encontrada foi de 4,18% em homem com ginecomastia. Conclusão: A reatividade dos receptores de estrogênio e progesterona é menor nos pacientes transexuais feminino para masculino que fizeram uso de androgênios do que em mulheres e homens biológicos. A taxa de expressão do Ki-67 também é menor nos transexuais.
Introduction: The female to male transsexual patients use androgens for a prolonged period and often without any medical supervision. Endogenous androgens have inhibitory effects on breast tissue, while exogenous testosterone may exert an indirect effect on the breast because of its aromatization into estrogen and it may even increase the risk of breast cancer. The Ki-67 is one of the most used antibodies for evaluation of cell proliferation. Objectives: Evaluate the expression of estrogen and progesterone receptors and Ki-67 expression in breast tissue of female to male transsexuals, biological women and men with gynecomastia. Methods: The study consists of a case series of 17 patients, 5 transgender submitted to adenomastectomy as part of their treatment at the Service to Transgenders provided by the "Hospital das Clínicas" of the Federal University of Goiás, 4 women who underwent breast reduction and 8 biological men that underwent surgery for gynecomastia. All surgical specimens were evaluated by immunohistochemistry. Results: The transsexuals had a lower rate of expression of estrogen and progesterone receptors compared with biological men and women, and in all patients using androgen the expression of Ki-67 was ≤1%. The highest rate of expression of Ki-67 was 4.18% in a man with gynecomastia. Conclusion: The expression of estrogen and progesterone receptor is lower in female to male transsexual patients who used androgens in relation to biological men and women. The rate of expression of Ki-67 is also lower in transsexuals.
ABSTRACT
JUSTIFICATIVA E OBJETIVOS: Fragmentos de pele durante punções subaracnóideas podem desenvolver tumores epidermoides intraespinais. O objetivo deste estudo foi verificar a incidência de células epiteliais que refluem junto com a primeira e terceira gotas de líquor de pacientes submetido a raquianestesia. MÉTODO: Foram obtidas amostras da primeira e terceira gotas de líquor em 39 pacientes adultos submetidos à raquianestesia com agulha 25G Quincke, sendo confeccionadas quatro lâminas: da primeira gota, da terceira gota, da agulha e uma quarta lâmina controle com uma gota de soro fisiológico. As lâminas foram examinadas de forma randomizada pelo patologista. RESULTADOS: Foram identificadas células epiteliais escamosas em 35 (89,7%) das amostras da primeira gota, em 34 (87,2%) da terceira gota e em 24 (61,5%) das agulhas espinais. A terceira gota apresentou em média maior número de células que a primeira gota (p = 0,046). Células epiteliais nucleadas foram encontradas em uma (2,56%) das amostras da primeira gota, em quatro (10,25%) da terceira gota e em uma (2,56%) das agulhas espinais. A terceira gota apresentou em média maior número de células nucleadas que a primeira gota sem diferença estatística (p = 0,257). CONCLUSÕES: Encontramos uma alta porcentagem de células epiteliais que refluem na primeira (89,7%) e na terceira (87,2%) gotas do líquor e nas agulhas utilizadas (61,5%). Mesmo utilizando agulhas de pequeno calibre, descartáveis e com mandril bem adaptado, foram encontradas células da pele.
BACKGROUND AND OBJECTIVES: Skin fragments during lumbar punctures may develop intraspinal epidermoid tumors. The aim of this study was to determine the incidence of epithelial cells that reflow along with the first and third drops of CSF of patients undergoing spinal anesthesia. METHODS: Samples of the first and third drops of cerebrospinal fluid were collected from 39 adult patients undergoing spinal anesthesia with a 25G Quincke needle. Four microscope slides were prepared: one for the first drop, one for third drop, one for the needle, and one with a drop of saline for control. A pathologist examined the slides randomly. RESULTS: Squamous epithelial cells were identified in 35 (89.7%) samples from the first drop, 34 (87.2%) from the third drop, and 24 (61.5%) from spinal needle. The third drop showed a mean number of cells larger than the first drop (p = 0.046). Nucleated epithelial cells were found in a sample of the first drop (2.56%), in four samples of third drop (10.25%), and in one spinal needle (2.56%). Third drop showed a mean number of nucleated cells higher than first drop with no statistical difference (p = 0.257). CONCLUSIONS: High percentage of epithelial cells was found in the first (89.7%) and third (87.2%) drops of CSF reflow and in used needles (61.5%). Skin cells were found even using small gauge disposable needles with well-adapted mandrel,.

O câncer de mama apresenta alta heterogeneidade clínica, morfológica e biológica, fato esse justificado pela existência de diversas formas moleculares. Diferentes perfis de expressão gênica foram caracterizados, possibilitando a identificação de subtipos moleculares distintos, com fatores prognósticos e alvos terapêuticos específicos. Esta revisão foi conduzida utilizando artigos científicos das bases de dados MEDLINE, SciELO, LILACS e PubMed e teve como objetivo discutir os subtipos moleculares do câncer de mama e suas principais características. O subtipo luminal A apresenta, com relação aos demais, o melhor prognóstico. Na sua maioria, são tumores histologicamente de baixo grau e apresentam resposta inferior à quimioterapia, enquanto, tumores luminais B apresentam maior proliferação e são, muitas vezes, de alto grau histológico. O subtipo superexpressão do receptor tipo 2 do fator de crescimento epidérmico humano (HER2), sem a terapia adjuvante sistêmica, tem menor sobrevida livre de doença e elevada taxa de recorrência, porém se beneficia de terapias alvoespecíficas. O subtipo basaloide demonstra prognóstico mais reservado, associado à menor sobrevida livre de doença e à menor sobrevida global. A anatomia patológica e o teste de imunoistoquímica, através da classificação tumoral, são de fundamental relevância na abordagem terapêutica do carcinoma mamário. Para a atual classificação molecular por imunoistoquímica, recomenda-se a adoção do painel de fatores preditivos receptor de estrogênio (RE), receptor de progesterona (RP) e HER2 para todos os casos, adicionando-se outros marcadores, como o receptor tipo 1 do fator de crescimento epidérmico (EGFR), a citoceratina 5 e o Ki-67
Breast cancer has highly heterogeneous clinical, morphological and biological features, a fact that is justified by the existence of several molecular forms. Different gene expression profiles were characterized, enabling the identification of different molecular subtypes with specific prognostic factors and therapeutic targets. This review was conducted using scientific articles of the databases MEDLINE, SciELO, LILACS and PubMed, and aimed to discuss the molecular subtypes of breast cancer and their main characteristics. The luminal A subtype, when compared with the others, features the best prognosis. Most tumors are histologically low grade and have less response to chemotherapy, while luminal B tumors have high cell proliferation rate and are most often high grade. The enriched subtype to receptor 2 human epidermal growth factor (HER2), without adjuvant systemic therapy, has a lower disease-free survival and higher recurrence rate, but it benefits from target-specific therapies. The basal-like subtype pattern shows poor prognosis associated with lower disease-free survival and shorter overall survival. The pathology and immunohistochemistry test, by tumor classification, are of fundamental importance in the therapeutic management of breast cancer. For the current molecular classification by immunohistochemistry, the adoption of the panel of the predictive factors estrogen receptors (ER), receptors progesterone (PR) and HER2 is recommended for all cases of breast cancer, adding other markers such as epidermal growth factor receptor type 1 (EGFR), the cytokeratin 5 and the Ki-67

O estudo das neovaginas em mulheres e principalmente em transexuais masculinos operados inclui pequeno número de casos e conta com pouco detalhamento sobre o assunto. Algumas perguntas ainda estão por ser respondidas: é necessária a colpocitologia oncoparasitária? Se necessária, em que espaço de tempo? Devemos nos preocupar com a infecção pelo HPV? Quanto tempo é necessário para haver a completa metaplasia do epitélio utilizado? A flora bacteriana é semelhante? Com o objetivo de chamar a atenção para o tema, realizamos uma revisão bibliográfica, abordando aspectos cirúrgicos, oncocitopatológicos, histológicos e morfológicos de neovaginas de mulheres biológicas e transmulheres (transexuais masculinos).
The neovagina studies in women and mainly in operated male transsexuals (transwomen) are few and with few cases specified. Their follow-up is also difficult. Some questions have not been answered yet: is the oncologic colpocytology necessary? If it is necessary, what would the best time to do it? Shall we be worried about HPV infection? What is the necessary time to completely metaplasia? Is the bacterial flora similar? With the purpose of calling attention to this subject, we made a bibliography revision approaching cytological, histological and morphologic aspects of women and transwomen neovaginas (male-to-female transsexual).

Relatam-se dois casos clínicos de prolapso de gordura orbitária, sendo um associado à oftalmopatia de Graves. Os pacientes apresentavam em comum exame clínico com elevação na região temporal da órbita direita e aumento da gordura intraorbitária na tomografia computadorizada de órbitas. No caso da paciente com oftalmopatia de Graves observou-se também aumento do volume da musculatura orbital no exame de imagem. O trabalho busca incluir a oftalmopatia de Graves, quando nesta ocorre aumento da gordura orbital como diagnóstico diferencial do prolapso de gordura orbitária.
We report two cases of orbital fat prolapse. One associated with Graves' ophthalmopathy. Both patients presented similar clinical exams and an increase in intraorbital fat as seen in computerized orbital tomography. The patient with Graves' ophthalmopathy also presented an increased volume in orbital muscles in the tomography. This work seeks to include Graves' ophthalmopathy as differential diagnosys for Orbital fat prolapse.
ABSTRACT
OBJETIVO: Comparar o 2-octil cianoacrilato com o fio de "nylon" no fechamento da pele em ratos. MÉTODOS: Vinte e cinco ratos da linhagem Wistar, foram submetidos à incisão de 3 cm de cada lado do abdome. A síntese foi feita utilizando em um dos lados o "nylon" 4.0, pontos intradérmicos, e do outro o 2-octil cianoacrilato. Após sete dias, o fio foi removido e as incisões, analisadas quanto às complicações. Após 40 dias, o resultado da cicatriz foi avaliado. Os ratos foram sacrificados, as cicatrizes foram ressecadas, fixadas e enviadas ao patologista, sem informação sobre qual o método utilizado. RESULTADOS: Houve dois óbitos durante a anestesia e um tardio. O tempo de operação foi de 136 segundos com a cola e 176 segundos, com o "nylon" (P=0,003). Dentre as 50 operações realizadas, as complicações foram: um hematoma com cada método (P=0,80), quinze deiscências da cola contra 11 do "nylon" (P=0,20), sete cicatrizes de aspecto ruim ou razoável da cola contra quatro do "nylon" (P=0,30), três infecções na cola contra duas (P=0,40). Ao exame patológico, a mediana da largura da cicatriz foi de 1.119 micra com a cola e 1.800 com o "nylon" (P=0,40). A espessura foi de 1.795 contra 1.705 micra (P=0,40). CONCLUSÃO: O 2-octil cianoacrilato apresentou o mesmo aspecto cicatricial, a mesma resistência e as mesmas complicações que a sutura com o "nylon" 4.0, porém permitindo redução no tempo cirúrgico.
BACKGROUND: Tissue adhesive 2-octyl cyanoacrylate was developed to have more strength, less inflammatory reaction, and less histotoxicity than its shorter-chain derivates. METHODS: To evaluate the use of 2-octil cyanoacrylate in comparison with "nylon" suture in skin closure of rats. Methods: Twenty-five female Wistar rats were submitted to a 3cm surgical incision in each side of the abdomen. The wound was closed with intradermic suture using "nylon" 4-0 in one side, and 2-octil cyanoacrylate on the other side. After 7 days the thread was removed and the wound was checked for complications. After 40 days the wound aspect was clinically evaluated. The rats were sacrificed; the scars were resected, and sent to the pathologist without the information of which closing method was used. RESULTS: There were 2 deaths during anesthesia or few days after surgery. The mean surgical time was 136 seconds with the adhesive and 176 with "nylon" (P=0.003). The complications were: one hematoma in each method (P=0.8), fifteen wound dehiscence with the adhesive and 11 with "nylon" (P=0.2), seven scars with a bad or fair aspect with adhesive and 4 with "nylon" (P=0.3), three infections with adhesive and 2 with "nylon" 2 (P=0.4). Histological examination showed median scar width of 1.119 micron with the adhesive and 1.800 with "nylon" (P=0.7). The mean thickness was 1.795 in the adhesive group versus 1.705 micron (P=0.7). CONCLUSION: Surgical adhesive showed the same aesthetical results, the same strength, and the same complications as for "nylon" 4.0 sutures, but the adhesive decreased the surgical time.
ABSTRACT
Introdução: Estudos dos fatores de risco para os cânceres de boca e orofaringe constituem-se em relevante ferramenta para políticas de promoção e prevenção da saúde. Alguns fatores, como o tabagismo e o etilismo, são amplamente estudados; outros, como a ocupação, carecem de mais estudos. Objetivos: Verificar os fatores de riscos associados ao câncer de boca e orofaringe. Métodos: Estudo caso-controle multicêntrico entre o RCBP-Goiânia e a IARC. Os casos foram selecionados no Serviço de Cabeça e Pescoço do Hospital Araújo Jorge, Goiânia. Os controles foram pacientes de dois hospitais da Rede Pública Estadual de Saúde, não especializados em Oncologia, em Goiânia. Foram avaliadas as exposições, classificadas conforme a descrição do IARC (1987). Foram utilizados os testes de qui-quadrado e o teste T de Student, quando aplicáveis. A associação entre a variável dependente (câncer) e as variáveis independentes (as exposições aos agentes carcinogênicos) foi estimada pelo cálculo da OR bruta e da ajustada por tabagismo, por etilismo e por origem de residência, com IC de 95%. Resultados: Foram selecionados 200 (41,8%) pacientes considerados casos e 279 controles (58,2%). A análise multivariada demonstrou que a fumaça de cromatos, os pigmentos, os pó de algodão, o aerosol de animais, os pesticidas e a poeira de madeira foram fatores de risco independentes para o câncer de boca e orofaringe. Conclusão: A exposição ocupacional às substâncias carcinogênicas em ambientes de trabalho também são fatores de risco para o câncer de boca e orofaringe; portanto, a adoção de uma política de prevenção pelos órgãos fiscalizadores do trabalho, bem como campanhas mais efetivas contra o hábito de fumar e o uso de bebidas alcoólicas podem promover a redução desse tipo de câncer em grandes populações.
Introduction: Researches about the risk factors for oral and oropharyngeal cancer constitute in a relevant tool for politics of health promotion and prevention. Some factors as tobacco smoking and alcohol are widely studied; others such as occupation ask for further research. Objective: To verify the risk factors associated to oral and oropharyngeal cancer. Methods: a prospective multicentric case-control between RCBP- Goiânia and IARC. The cases were selected from the Head and Neck Service at Araújo Jorge Hospital, Goiânia. The controls were patients from two public hospitals not specialized in Oncology, in Goiânia. The expositions classified according to IARC's description (1987) were evaluated. The chi-squared test and Student's T test were used, when applicable. The association between the dependent variable (cancer) and the independent variables of exposition to the carcinogenic agents were estimated by calculating the gross OR and adjusted by tobacco smoking, alcohol and residence origin with a 95% IC. Results: 200 patients (41.8%) considered cases and 279 (58.2%) controls were selected. The multivariated analysis showed that chromate smoke, pigments, cotton powder, animals' aerosol, pesticides and wood dust were independent risk factors to oral and oropharyngeal cancer. Conclusion: The occupational exposition to carcinogenic substances in work environment are risk factors to oral and oropharyngeal cancer. Therefore, the adoption of prevention politics by the work controlling agencies, as well as more effective campaigns against the smoking habit and the use of alcoholic beverages may promote the reduction of this kind of cancer in large populations.
ABSTRACT
In developed countries, oral cancer is the eightieth most common cancer type, whereas in the developing world it is the fourth most common type of the disease. Known risk factors for oral cancer are smoking, alcohol consumption, poor oral hygiene, poorly-fitting dentures. This study analyzed sociodemographic and dietary factors as risk factors for cancer of the mouth and oropharynx. Patients and Methods: This case-control study was carried out from November 1998 to June 2003. The cases were patients with a diagnosis of squamous cell carcinoma of the mouth and oropharynx at the Araujo Jorge Hospital in Goiania, Goias, Brazil. Controls were selected in two public general hospitals of Goiania with no oncologic departments. Results: The study consisted of 200 cases (41.8%) and 279 controls (58.2%). Multivariate analysis, adjusted for smoking, alcohol consumption and place of residence, showed that fish, fresh tomatoes, citric fruit, apples and pears consumption was a protective factor, while cakes and desserts remain as independent risk factors. Conclusions: Dietary habits are important in the prevention of oral and oropharyngeal cancer. Healthy dietary habits should be stimulated through educational campaigns, the objective of which should also be to combat alcohol and tobacco consumption.
