Introduction: Anal examination and videoanoscopy (VA) are rarely performed during colonoscopies. In recent years, there has been a considerable increase in lesions of sexually transmitted anal and rectal infections, but these conditions are not noticed or reported during routine colonoscopy. Objective: To raise awareness regarding the fortuitous findings of lesions and sexually transmitted infections (STIs) in colonoscopy exams and to demonstrate that anal examination and VA provide important information and should be routinely performed. Methods: We conducted a descriptive retrospective study in 16,132 patients screened by colonoscopy and VA between 2006 and 2018. Among numerous other findings, the presence of anal condylomata and sexually transmitted retitis or perianal dermatitis was observed. The rates of each finding were calculated, and the patients were subdivided by sex and into age groups by blocks of ten years. Results: Among the 16,132 colonoscopies performed, 26 cases of condyloma (0.16%) and 50 cases of proctitis or perianal dermatitis suspicious for STI (0.33%) were found. Conclusion: Performing anal examination and VA systematically in all routine colonoscopies enabled the identification of numerous anal conditions, including several fortuitous cases of STIs. The study proposes that anal examination and VA should be performed in all routine colonoscopies and, in suspected cases, complementary tests for STIs. (AU)

Objective: To investigate the natural regression and related factors of high-grade squamous intraepithelial lesion (HSIL) in the cervix of childbearing age women, and to evaluate the applicability of conservative management for future fertility needs. Methods: This study included 275 patients of reproductive age with fertility needs, who were diagnosed as HSIL by biopsy from April 30, 2015 to April 30, 2022, including 229 cases (83.3%) cervical intraepithelial neoplasia (CIN) Ⅱ and 46 cases (16.7%) CIN Ⅱ-Ⅲ. They were followed-up without immediate surgery in the First Affiliated Hospital of Nanjing Medical University. The median follow-up time was 12 months (range: 3-66 months). The regression, persistence and progression of lesions in patients with HSIL were analyzed during the follow-up period, the influencing factors related to regression and the time of regression were analyzed. Results: (1) Of the 275 HSIL patients, 213 cases (77.5%, 213/275) experienced regression of the lesion during the follow-up period. In 229 CIN Ⅱ patients, 180 cases (78.6%) regressed, 21 cases (9.2%) persisted, and 28 cases (12.2%) progressed. In 46 CIN Ⅱ-Ⅲ patients, 33 cases (71.7%) regressed, 12 cases (26.1%) persisted, and 1 case (2.2%) progressed to invasive squamous cell carcinoma stage Ⅰ a1. There was no significant difference in the regression rate between the two groups (χ2=1.03, P=0.309). (2) The average age at diagnosis, age <25 years old at diagnosis were independent influencing factor of HSIL regression in univariate analysis (all P<0.05). There was no significant difference between HSIL regression and pathological grading, the severity of screening results, human papillomavirus (HPV) genotype, colposcopy image characteristics, number of biopsies during follow-up and pregnancy experience (all P>0.05). (3) The median regression times for patients aged ≥25 years and <25 years at diagnosis were 15 and 12 months, respectively. Kaplan-Meier analysis showed that age ≥25 years at diagnosis significantly increased the median regression time compared to <25 years (χ2=6.02, P=0.014). Conclusions: For HSIL patients of childbearing age, conservative management without immediate surgical intervention is preferred if CINⅡ is fully evaluated through colposcopy examination. Age ≥25 years at diagnosis is a risk factor affecting the prognosis of HSIL patients.

BACKGROUND@#Gallbladder cancer (GBC) is the most common malignant tumor of biliary tract. Isoliquiritigenin (ISL) is a natural compound with chalcone structure extracted from the roots of licorice and other plants. Relevant studies have shown that ISL has a strong anti-tumor ability in various types of tumors. However, the research of ISL against GBC has not been reported, which needs to be further investigated.@*METHODS@#The effects of ISL against GBC cells in vitro and in vivo were characterized by cytotoxicity test, RNA-sequencing, quantitative real-time polymerase chain reaction, reactive oxygen species (ROS) detection, lipid peroxidation detection, ferrous ion detection, glutathione disulphide/glutathione (GSSG/GSH) detection, lentivirus transfection, nude mice tumorigenesis experiment and immunohistochemistry.@*RESULTS@#ISL significantly inhibited the proliferation of GBC cells in vitro . The results of transcriptome sequencing and bioinformatics analysis showed that ferroptosis was the main pathway of ISL inhibiting the proliferation of GBC, and HMOX1 and GPX4 were the key molecules of ISL-induced ferroptosis. Knockdown of HMOX1 or overexpression of GPX4 can reduce the sensitivity of GBC cells to ISL-induced ferroptosis and significantly restore the viability of GBC cells. Moreover, ISL significantly reversed the iron content, ROS level, lipid peroxidation level and GSSG/GSH ratio of GBC cells. Finally, ISL significantly inhibited the growth of GBC in vivo and regulated the ferroptosis of GBC by mediating HMOX1 and GPX4 .@*CONCLUSION@#ISL induced ferroptosis in GBC mainly by activating p62-Keap1-Nrf2-HMOX1 signaling pathway and down-regulating GPX4 in vitro and in vivo . This evidence may provide a new direction for the treatment of GBC.

Las neoplasias intraepiteliales córneo-conjuntival son lesiones premalignas, mal delimitadas, de crecimiento lento y escaso potencial de malignización. Solo el 9 por ciento progresa a carcinoma invasor de células escamosas. Posee varias formas de presentación y tiene múltiples dilataciones vasculares. La displasia epitelial corneal primaria es una forma poco frecuente de neoplasia intraepitelial córnea-epitelial. Se presenta un caso clínico confirmado por estudios anatomopatológicos. En el presente estudio se observó respuesta satisfactoria luego de un mes de tratamiento tópico con 5FU, sin efectos colaterales. El seguimiento durante tres años no ha mostrado signos de recidiva(AU)

Corneal-conjunctival intraepithelial neoplasms are premalignant, poorly demarcated, slow-growing lesions with low malignant potential. Only the 9 percent progresses to invasive squamous cell carcinoma. It appears in several forms and presents multiple vascular dilatations. Primary corneal epithelial dysplasia is a rare form of corneal-epithelial intraepithelial neoplasia. We present a clinical case, confirmed by anatomopathologic studies. In the present study we observed a satisfactory response after one month of topical treatment with 5FU, with no side effects. Follow-up for three years has shown no signs of recurrence(AU)

Objectives: To compare morphological abnormalities on anal colposcopy against histology to determine anal high-grade squamous intraepithelial lesions (HSILs). Methods: This is a retrospective data assessment of HIV-negative and HIV-positive patients undergoing outpatient follow-up. The sample comprised 54 patients presenting acetowhite lesions on anal colposcopy. Acetowhite lesions were classified according to their morphology into punctation, verrucous, mosaic, ulcerated, or hypervascularized, and biopsies of these specimens were classified as anal HSIL, low-grade squamous intraepithelial lesion (LSIL), or normal. The data were analyzed using SPSS forWindows version 13.0 (SPSS Inc., Chicago, IL, USA). The results were analyzed using the nonparametric Mann-Whitney test, the Fisher exact test and the chi-squared parametric test. A 95% confidence interval (CI) was used and a level of significance <5% was adopted for all statistical tests. Results Fifty-four patients (50 males, 80% HIV+) with biopsied acetowhite lesions were assessed. There were 31 punctation lesions, 1 classified as HSIL (3.2%; 95%CI: 0- 40.0), 17 verrucous lesions, 3 HSIL (17.7%; 95%CI: 0-10.7), and 1 ulcerated, classified as HSIL (100%), and 4 mosaic and 1 atypical vessel lesion, all classified as LSIL. The results showed no association of presence of anal HSIL with positivity for HIV infection or with counts above or below 500/µl in HIV+patients. Statistical analysis was performed using the Mann-Whitney nonparametric test, the Fisher exact test, and the chi-squared parametric test. Conclusion: The comparison of morphological findings on anal colposcopy against histology revealed no morphological pattern suggesting anal HSIL. (AU)

Abstract Currently, pagetoid dyskeratosis is believed to involve an accelerated keratinization process, possibly induced by mechanical trauma. It represents, in almost its totality, incidental histological findings of specific cells, except when it occurs in the hands, where it usually occurs simultaneously with skin lesions and local dyschromia. These are large, rounded keratinocytes, with pale cytoplasm and a pyknotic nucleus surrounded by a clear halo, which can be easily mistaken by other skin diseases. Its etiology is not completely elucidated, and the correct identification of this entity can be of great importance in the differential diagnosis of skin disorders and the understanding of the keratinization process of the epidermis.

Oncocytoma of the eyelid is a rare neoplasm. Oncocytoma associated with an ocular surface squamous neoplasm, namely conjunctival intraepithelial neoplasia, is very hard to find in the literature. Herein we report a case of a 53-year-old male who presented with a swelling in the right lower lid over the last 6 years, along with a growth in the conjunctiva of the same eye for the last 2 years and encroaching upon the cornea for the last 4 months. Excision biopsy of the lower lid mass showed histopathological features consistent with oncocytoma. The conjunctival tissue revealed conjunctival intraepithelial neoplasia 3 (severe dysplasia). This case documents a rare synchronous dual ocular neoplasia, a very unlikely coexistence of oncocytoma with conjunctival intraepithelial neoplasia.

Apesar de fibroadenoma ser uma das lesões mais comuns da mama, sua correlação a alteração maligna é rara.1,2,3,5,7 Quando ocorre tem apresentação clínica similar a dos fibroadenomas típicos, diagnóstico anatomopatológico em geral pós-cirúrgico e tratamento conforme do carcinoma do mesmo tipo histológico isolado.1,2,3,4,6 Apresentamos caso de mulher de 52 anos, apresentando em propedêutica investigativa nódulo em mama direita. Core-biopsy sugeriu carcinoma ductal in situ desenvolvido dentro de fibroadenoma, confirmado em análise anatomopatológica pósoperatória. Tratamento e seguimento se deu conforme já estabelecido pela literatura para carcinoma in situ. Devido baixa incidência, há poucas evidências científicas quanto ao diagnóstico, tratamento e prognóstico desse tipo de lesão. Portanto, apresentar à comunidade científica casos de carcinoma inclusos a fibroadenoma se faz relevante.

Although fibroadenoma is one of the most common lesions of the breast, its correlation with malignant changes is rare. When it occurs, the clinical presentation is similar to typical fibroadenomas, anatomopathological diagnosis is after surgery and treatment goes according to the carcinoma histological type. A case of a 52-year-old woman is presented, with an impalpable nodule in the right breast, diagnosed from screening exams. Corebiopsy suggested carcinoma ductal in situ developed within fibroadenoma, confirmed in the postoperative anatomopathological analysis. Treatment and follow-up followed as established in the literature for carcinoma in situ. Due the low incidence, there are poor scientific evidence regarding the diagnosis, treatment and prognosis of this type of injury. Therefore, presenting cases of Carcinoma ductal in situ arising in a fibroadenoma to the scientific community is so relevant.

Objetivo: Relatar o acompanhamento de gestação planejada, parto e puerpério de paciente em seguimento prévio a gestação de lesão intraepitelial de alto grau (câncer in situ) após realização de conização e reconização, com persistência da lesão. Métodos: Foi realizada análise de prontuário da paciente e comparação da evolução com a bibliografia. Resultados: A paciente foi acompanhada com colpoci- tologia oncológica, desde o diagnóstico de gravidez até o puerpério, apresentando resultados negativos para neoplasia. Conclusão: A decisão da paciente de gestar foi respeitada e ela teve assistência e cuidados durante todo o pré-natal, com seguimento e controle da sua lesão. Tal decisão poderia comprometer seu futuro se a lesão evoluísse. Porém, com a regressão total, pode-se pensar que a paciente poderia ter perdido a oportunidade de gestar, com um desfecho favorável, além de ser submetida a um procedimento cirúrgico definitivo importante, com conse- quências psicológicas.(AU)

Objective: To report on the follow-up of planned pregnancy, childbirth and the puer- perium of a patient who was following the pregnancy prior to pregnancy of a high- -grade intraepithelial lesion (cancer in situ) after conization and reconditioning, with persistence of the lesion. Methods: Analysis of the patient's medical record and com- parison of progress with the bibliography was performed. Results: The patient was followed up with oncological colpocytology, from the diagnosis of pregnancy until the puerperium, showing negative results for neoplasia. Conclusion: The patient's decision to gestate was respected, and she had assistance and care throughout the prenatal period, with follow-up and control of her injury. Such a decision could jeo- pardize your future if the injury evolves. However, with total regression, it can be thought that the patient could have missed the opportunity to gestate, with a favo- rable outcome, in addition to undergoing an important definitive surgical procedure and its psychological consequences.(AU)

Stratified mucin-producing intraepithelial lesion (SMILE) is an intraepithelial lesion with overlapping features of the high-grade squamous intraepithelial lesion (HSIL) and adenocarcinoma in situ (AIS). Currently, it is well described in the cervix. We present a case showing similar SMILE-like lesions in the polypectomy specimen from the anal canal along with invasive adenocarcinoma components. This lesion showed an immuno-profile characteristic of a SMILE lesion described in the cervix, such as p63 negativity, high ki67 index, and nuclear positivity for p16. It might be arising from the Human papillomavirus prone transitional region of the anal canal as described in the cervix. However, we could not assure this association and etiological link due to insufficient material in the formalin-fixed paraffin-embedded block. Notwithstanding, we strongly suggest that the HPV is the main driver for this SMILE-like lesion similar to what is described in the cervix. To our knowledge, this is the first case report of a SMILE lesion in the anal canal. Further studies will be required to elucidate the underlying pathogenetic mechanism of SMILE-like lesions described in the anal canal.

BACKGROUND@#Endoscopic biopsy can underestimate gastric malignancies as low-grade intraepithelial neoplasia (LGIN). Definitively diagnosed LGIN would progress. This study aimed to evaluate predictive factors to identify malignancies misdiagnosed as LGIN by biopsy and LGIN at high risk of progression.@*METHODS@#The clinical records of patients diagnosed with gastric LGIN by endoscopic biopsy who underwent at least two endoscopies during the first year of follow-up between 2007 and 2017 were retrospectively collected. Three endoscopists reviewed photographs of the initial endoscopy, described lesion characteristics, and made endoscopic diagnoses. Logistic regression was used to analyze predictors to identify malignancies underestimated as LGIN. A receiver operating characteristic curve was used to evaluate the diagnostic accuracy of these predictors. Patient clinical outcomes of follow-up >1 year were collected. Kaplan-Meier estimates with log-rank tests and Cox proportional hazards regression were used to analyze predictors of progression.@*RESULTS@#Overall, 48 of 182 (26.4%) patients were proven to have malignancies. A single lesion, a large lesion size, and marked intestinal metaplasia (IM) were independent predictors of initially misdiagnosed malignancies. The area under the curve of these predictors was 0.871, with a sensitivity of 68.7% and specificity of 92.5%. Twelve of 98 patients (12.2%) progressed during the 33-month median follow-up period. A whitish appearance, irregular margins, marked IM, and histological diagnosis of LGIN more than twice within the first year were predictors for progression.@*CONCLUSIONS@#Lesions diagnosed as LGIN by biopsy with marked IM and other predictors above should be prudently treated for high potential to be malignancies or progress. Endoscopic follow-up with repeated biopsies within the first year is recommended.

Abstract Introduction: Anal intraepithelial neoplasia (AIN) is the most likely precursor of squamous cells cancer which represents 90% of anal cancers. The use of biomolecular tests as a screening method has been extended by gynecology. Given the similarities that exist between the HPV disease in the lower genital tract and anorectal sectors, it is expected that HPV tests can provide information for the diagnosis, treatment and follow-up for AIN-affected patients. Objectives: Comparing the performance of anal cytology, PAP and HPV tests (Hybrid Capture and Papillocheck) against the histology of the diagnosis of low- and high-grade AIN in risk groups. Material and methods: A cross-sectional study was carried out to evaluate diagnostic methods for low- and high-grade AIN in 73 patients. Samples for anal PAP, Papillocheck and Hybrid Capture were taken from all patients who then, regardless of the results, underwent magnifying chromoendoscopy (MCE) along with biopsy. Diagnostic test performances and their 95% confidence intervals (CI: 95%) were calculated as well as the likelihood ratio for each test. Results: Of the 73 patients, 49 (67%) were women. The average age of the patients was 38 years. In 38 patients (52%), the histology was positive with 10 (14%) grade II AIN or higher. There were no statistically significant differences in sensitivity nor in specificity for low- and high-grade AINs between any of the tests. Conclusion: Anal PAP, the Hybrid Capture test (HC2, Qiagen) and PapilloCheck (Greiner Bio One) were highly sensitive but not specific for low- and high-grade AINs. Therefore, a biopsy should be conducted against a positive result of any of the tests to confirm AIN and the degree of dysplasia. The screening method selection depend on the availability but also costs of the test should be considered, since all the diagnostic tests have similar performance.

Resumo Introdução: A neoplasia intraepitelial anal é o precursor mais provável do câncer de células escamosas, que representa 90% dos tumores anais. O uso de exames biomoleculares como método de triagem foi ampliado pela ginecologia. Considerando-se as semelhanças entre as apresentações de HPV no trato genital inferior e anorretal, espera-se que os exames de HPV possam fornecer informações para o diagnóstico, tratamento e acompanhamento dos pacientes com neoplasia intraepitelial anal. Objetivo: Comparar o desempenho da citologia anal, Papanicolau, exames para HPV (teste de captura híbrida e Papillocheck) e histologia no diagnóstico de neoplasia intraepitelial anal de baixo e alto grau em grupos de risco. Material e métodos: Foi realizado um estudo transversal para avaliar métodos de diagnóstico de neoplasia intraepitelial anal de baixo e alto grau em 73 pacientes. Amostras para Papanicolau anal, Papillocheck e captura híbrida foram coletadas de todos os pacientes; independentemente dos resultados desses exames, todos foram submetidos a cromoendoscopia de ampliação (CEA) e biópsia. O desempenho dos exames e seus intervalos de confiança de 95% (95% CI) foram calculados, bem como a razão de verossimilhança para cada teste. Resultados: Dos 73 pacientes, 49 (67%) eram mulheres. A idade média dos pacientes foi de 38 anos. A histologia foi positiva em 38 pacientes (52%), dos quais dez (14%) apresentaram neoplasia intraepitelial anal grau II ou superior. Não foram observadas diferenças estatisticamente significativas na sensibilidade ou especificidade para as neoplasias intraepiteliais anal de baixo e alto grau entre qualquer um dos exames. Conclusão: O Papanicolau anal, o teste de captura híbrida (HC2, Qiagen) e o Papillocheck (Greiner Bio One) foram altamente sensíveis, mas não específicos para neoplasia intraepitelial anal de baixo e alto grau. Portanto, uma biópsia deve ser realizada após um resultado positivo em qualquer um dos testes para confirmar o diagnóstico de neoplasia intraepitelial anal e seu grau. A seleção do método de triagem depende da disponibilidade, mas os custos devem ser considerados, uma vez que todos os testes apresentam desempenho semelhante.

Objetive: To characterize patients diagnosed with oral epithelial dysplasia and carcinoma in situ, according to their severity, location, age, sex and smoking habits. Materials and Methods: A descriptive study, based on 126 histopathological reports of biopsies diagnosed with mild, moderate, severe epithelial dysplasia and carcinoma in situ, with information regarding anatomical location, age and gender of the patient, recorded in the biopsy reports of the histopathology services of the Faculty of Dentistry of Andrés Bello University and Major University, between the years 2000 and 2014. The dichotomous qualitative variables were described based on percentage and age using the Shapiro-Wilk test, presenting as average and standard deviation, in the STATA 12® program (StataCorpLP, Texas, USA). Result: A similar frequency was found for men and women diagnosed with OED, 53.17% and 46.83% respectively. A mild degree of OED was the most diagnosed in both sexes. The group most affected by OED was between 50 and 69 years old (57.94%) and the most frequent anatomic location was the lateral border of the tongue (34.13%). Conclusion: Most of the analyzed cases corresponded to mild degrees of dysplasia; however, it is important to always carry out a histopathological diagnosis of the lesion, patient follow-up and education regarding risk habits.

Objetivo: Caracterizar a pacientes con diagnóstico de displasia epitelial oral (DEO) y carcinoma in situ (CIS) según su severidad, localización, edad, género y hábito tabáquico. Materiales and Métodos: Se realizó un estudio descriptivo, en base a 126 informes histopatológicos de biopsias diagnosticadas con displasia epitelial leve, moderada, severa y carcinoma in situ, que contaban con información relativa a localización del diagnóstico, edad y género del paciente, registrados en los informes de biopsias de los servicios de histopatología de la Facultad de Odontología de la Universidad Andrés Bello y Universidad Mayor, entre los años 2000 y 2014. Las variables cualitativas dicotómicas se describieron en base a porcentaje y la edad mediante el test de Shapiro-Wilk, presentándose como media y desviación estándar, en el programa STATA 12 ® (StataCorpLP, Texas, USA). Resultados: Se encontró una frecuencia levemente aumentada de mujeres y hombres con diagnóstico de DEO, 67 (53,17%) y 59 (46,83%), respectivamente. El grado leve de DEO fue el más diagnosticado en ambos sexos. El grupo más afectado por DEO fue entre los 50 a 69 años (57,94%) y la localización anatómica más frecuente fue el borde lateral de la lengua (34,13%). Conclusión: La mayoría de los casos analizados correspondieron a grados leve de displasia; no obstante, es importante realizar siempre un diagnóstico histopatológico de la lesión, seguimiento al paciente y educación en cuanto a hábitos de riesgo.

Introducción: El virus de papiloma humano per se no es capaz de desarrollar todas las transformaciones neoplásicas en el cérvix uterino, de manera que factores de riesgo como los genéticos, ambientales, estilo de vida sexual y el desbalance oxidativo podrían contribuir a la enfermedad. Objetivo: Determinar el comportamiento del sistema enzimático antioxidante en mujeres con atipia de células escamosas de significado indeterminado y neoplasia intraepitelial cervical grado I. Métodos: Se conformaron tres grupos de estudio: el primero incluyó 30 mujeres con diagnóstico de atipias, el segundo se constituyó con 40 mujeres con neoplasia intraepitelial grado I y el tercero consistió en 30 mujeres con citología negativa tomadas como control, provenientes de la consulta de Patología de Cuello del Agustín Gómez Lubián de Santa Clara. Mediante métodos espectrofotométricos se determinaron los niveles de actividad enzimática superóxido dismutasa y catalasa así, como las concentraciones de glutatión reducido. Las comparaciones se realizaron con el programa SPSS, versión 18. Resultados: En el grupo de atipias aunque los tres parámetros tuvieron una tendencia a la disminución no hubo diferencias significativas con respecto al control. Mientras que el grupo de neoplasia grado I evidenció disminución significativa de los tres indicadores estudiados al ser comparados con el grupo control. Conclusiones: Se constató afectación del sistema antioxidante enzimático en el grupo de neoplasia grado I, lo cual podría considerarse un cofactor importante en la progresión de las lesiones en el cérvix uterino(AU)

Introduction: Human papillomavirus per se can not carry out all the neoplastic transformations occurring in the uterine cervix. Genetic and environmental risk factors as well as sexual behavior and oxidative imbalance may also play a role. Objective: Determine the behavior of the enzymatic antioxidant system in women with squamous cell atypia of indeterminate significance and grade I cervical intraepithelial neoplasia. Methods: Three study groups were formed. The first group included 30 women diagnosed with atypia, the second group was made up of 40 women with grade I intraepithelial neoplasia, and the third or control group consisted of 30 women with negative cytology from Agustín Gómez Lubián Cervical Pathology service in Santa Clara. Spectrophotometric methods were used to determine the levels of superoxide dismutase and catalase enzymatic activity, as well as the concentrations of reduced glutathione. Comparisons were made with the SPSS software, version 18. Results: In the atypia group the three parameters showed a decreasing tendency, but differences with respect to the control group were not significant. In the grade I neoplasia group, however, a significant reduction was found of the three study indicators when compared with the control group. Conclusions: Damage to the enzymatic antioxidant system was observed in the grade I neoplasia group. This could be considered to be an important cofactor in the progress of uterine cervix lesions(AU)

Abstract Objective: To describe the epidemiological, clinical and laboratory profiles of women with anal neoplasia associated with cervical neoplasia attending a tertiary healthcare facility in northeastern Brazil. Methods: This epidemiological, descriptive study was conducted using a database from a cross-sectional study carried out between December 2008 and January 2016. Women with a diagnosis of cervical neoplasia associated with anal neoplasia were included in the present study. Results: Of the women with cervical neoplasia, 14% were found to have an anal intraepithelial lesion or anal cancer. Median age was 33 years, 68% were non-white, and 70% were from urban regions, had little schooling and low income. Most reported having had anoreceptive (73%) and unprotected intercourse (84%). Regarding symptoms, 7% reported bleeding and 11% pruritus. Overall, 10% of the sample tested positive for the human immunodeficiency virus. Anal cytology was abnormal in 92%. High-resolution anoscopy was abnormal in all cases. Histopathology revealed three cases of invasive carcinoma and high-grade lesions in 32% of the cases. Conclusion: Women with a diagnosis of anal and cervical neoplasia are often young, non-white women, who initiated their sexual life at an early age, were exposed to unprotected anoreceptive intercourse, live in urban centers, have little schooling and a low-income level.

ABSTRACT Purpose The present study aimed to determine whether sarcopenia after radical cystectomy (RC) could predict overall survival (OS) in patients with urothelial bladder cancer (UBC). Materials and Methods The lumbar skeletal muscle index (SMI) of 80 patients was measured before and 1 year after RC. The prognostic significance of sarcopenia and SMI decrease after RC were evaluated using Kaplan-Meier analysis and a multivariable Cox regression model. Results Of 80 patients, 26 (32.5%) experienced sarcopenia before RC, whereas 40 (50.0%) experienced sarcopenia after RC. The median SMI change was -2.2 cm2/m2. Patients with sarcopenia after RC had a higher pathological T stage and tumor grade than patients without sarcopenia. Furthermore, the overall mortality rate was significantly higher in patients with sarcopenia than in those without sarcopenia 1 year after RC. The median follow-up time was 46.2 months, during which 22 patients died. Kaplan-Meier estimates showed a significant difference in OS rates based on sarcopenia (P=0.012) and SMI decrease (P=0.025). Multivariable Cox regression analysis showed that SMI decrease (≥2.2 cm2/m2) was an independent predictor of OS (hazard ratio: 2.68, confidence interval: 1.007-7.719, P = 0.048). Conclusions The decrease in SMI after surgery might be a negative prognostic factor for OS in patients who underwent RC to treat UBC.

Pancreatic intraepithelial neoplasia (PanIN) is considered a pre-malignant lesion difficult to identify by imaging methods. EUS- FNA is an effective technique to obtain material for histopathological study of pancreatic cystic tumors, but it is not free of adverse events. We report a case of a 56 years old patient, with chronic abdominal pain (early 1994). MRI showed pancreatic cystic images. The etiologic diagnosis was doubtful and EUS-FNA was performed. Immediately after a FNA, patient had an episode of acute pancreatitis, requiring hospitalization. During one year after FNA he had five episodes of AP. A new EUS suspected of PanIN, which was confirmed by surgery. After surgery the patient is well and has no more episodes of AP. Although the risk of AP, EUS-FNA should be performed to determine the best treatment for these patients with chronic abdominal pain who have cystic changes of pancreatic gland.

La neoplasia intraepithelial pancreática (PanIN) es considerada una lesión premaligna con dificultad diagnostica mediante métodos imagenlógicos. La EUS-FNA es una técnica efectiva para obtener material para el estudio histopatológico de tumores quísticos pancreáticos, pero no está libre de efectos adversos. Nosotros reportamos un caso de un paciente de 56 años de edad, con dolor abdominal cronico (desde 1994). En la resonancia abdominal se observó un quiste pancreático. El diagnostico etiológico fue dudoso y EUS-FNA fue realizada, después de la cual el paciente presento un cuadro de pancreatitis, requiriendo hospitalización. Durante el periodo de un año posterior a la FNA, éste presento cinco episodios de pancreatitis aguda. Un nuevo estudio ecoendoscopico dio la sospecha de PanIN, la cual se confirmó con la realización de la cirugía. Después de la cirugía quedo asintomático y sin presentar nuevos episodios de pancreatitis aguda hasta el momento. Aunque exista riego de pancreatitis aguda, la EUS-FNA debe realizarse para determinar el mejor tratamiento para pacientes con dolor abdominal crónico que tienen cambios quísticos de la glándula pancreática.

Introdução: O câncer cervical é atribuído ao papilomavírus humano (HPV) cuja infecção, na maioria das vezes, sofre regressão espontânea. A menor porção de casos que evoluem para lesão precursora de baixo e alto graus e invasora pode ter relação com uma falha na atividade das células de Langerhans em eliminar o vírus. Objetivo: Determinar se há redução do número de células de Langerhans em colos uterinos acometidos por neoplasias intraepiteliais cervicais (NIC), graus I e III, comparado ao grupo controle (cervicites crônicas), por imuno-histoquímica, possibilitando correlacionar a ação do sistema imune com o desenvolvimento dessas lesões. Método: Foram analisados 40 casos de cervicite crônica, NIC I e III, com diagnóstico anatomopatológico entre janeiro de 2014 e dezembro de 2015, buscando-se comparar a quantidade de núcleos marcados positivamente como célula de Langerhans pela proteína S-100 por imuno-histoquímica, quantificando-os em áreas padronizadas. Resultados: Dos 40 casos avaliados, 17 foram cervicite crônica, 13 NIC I e 10 NIC III. Na análise comparativa do número de células em cada grupo a média, desvio-padrão e mediana foram maiores no grupo cervicite crônica e menores no grupo NIC III. O valor de p encontrado para a variação do número de células de Langerhans, entre os grupos, foi significativo (p=0,0442); mas, ao comparar os grupos de NIC com o controle, só o grupo NIC III teve variação significativa (p=0,0209). Conclusão:Há diminuição significativa do número de núcleos de células de Langerhans marcados em lesões do tipo NIC III em comparação a cervicites crônicas.

Introduction: Cervical cancer is attributed to human papillomavirus (HPV), whose infection mostly undergoes spontaneous regression. The smaller part of cases that evolve to low and high-grade lesions or invasive lesions may be related to failure of Langerhans cell activity to eliminate the virus. Objective: To determine if there is reduction of Langerhans' cells in cervix uterus affected by cervical intraepithelial neoplasms (CIN) grades I and III compared to control group (chronic cervicitis) by immunohistochemistry, granting the correlation of the immune system action with the development of these lesions. Method: It were analyzed 40 cases of chronic cervicitis, CIN I and III with anatomopathological diagnosis between January 2014 and December 2015, attempting to compare the amount of positively labeled Langerhans cells nuclei by S-100 protein by immunohistochemistry, quantifying them in standard areas. Results: Of the 40 evaluated cases, 17 were chronic cervicitis, 13 CIN I and 10 CIN III. The comparative analysis of the number of cells in each group showed that the mean, standard deviation and median number of Langerhans cells per area were higher in the chronic cervicitis group and lower in the CIN III group. The p value found in the variation of the Langerhans cells number among the groups was significant (p=0.0442). However, when comparing the CIN groups directly with the control group, only the CIN III group had a significant variation (p=0.0209). Conclusion: There is a significant decrease in the number of marked Langerhans cell nuclei in CIN III type lesions compared to chronic cervicitis.

Introducción: El cáncer cervical puede atribuirse al virus del papiloma humano (VPH) cuya infección a menudo sufre regresión espontánea. El menor número de casos que evolucionan a lesiones precursoras de bajo y alto grado o invasivas puede estar relacionado con una falla en la actividad de las células de Langerhans para eliminar el virus. Objetivo: Determinar si hay reducción del número de células de Langerhans en colos uterinos acometidos por neoplasias intraepiteliales cervicales (NIC) grados I y III comparado al grupo control (cervicitis crónicas), por medio de inmunohistoquímica, posibilitando correlacionar la acción del sistema inmune con estas lesiones. Método: Se analizaron 40 casos de cervicitis crónica, NIC I y III, con diagnóstico anatomopatológico entre enero de 2014 y diciembre de 2015, comparando la cantidad de núcleos marcados positivamente como célula de Langerhans por la proteína S-100 por inmuno-histoquímica, cuantificándolos. Resultados: De 40 casos, 17 fueron cervicitis crónica, 13 NIC I y 10 NIC III. En el análisis comparativo del número de células en cada grupo la media, desviación estándar y mediana fueron mayores en el grupo cervicite crónica y menores en el NIC III. El valor de p encontrado para la variación del número de células de Langerhans entre los grupos fue significativo (p=0,0442), pero al comparar los grupos de NIC con el control sólo el grupo NIC III tuvo variación significativa (p=0,0209). Conclusión: Hay disminución significativa del número de núcleos marcados de células de Langerhans en lesiones de tipo CIN III en comparación con cervicitis crónica.
