Oral hairy polyp in a teenager: case report and literature review / Pólipo piloso oral em um adolescente: relato de caso e revisão de literatura

ABSTRACT Objective: To report an unusual case of oral hairy polyp (HP) and review the literature, providing epidemiological, clinical and histopathological information on this disease. Case description: A 12-year-old male patient was referred to a Stomatology department with a nodule in the posterior midline of the tongue. The patient did not know exactly when it arose or whether it had grown since then. Clinical exam revealed a bulky and mobile pedunculated mass lesion on the dorsum of the tongue, with a diameter of approximately 1 cm. The patient's mother reported no previous health problem. An excisional biopsy was performed, the surgical specimen was sent for anatomopathological analysis, and the findings were compatible with the diagnosis of HP. Comments: Hairy polyp is a rare lesion, especially in the oral region. The literature search revealed only 10 case reports of oral HP published between January 1999 and January 2019, and they revealed a predominance of the disease in female newborns. Two uncommon facts were presented in this case: the patient was male and diagnosis was made at 12 years old.

RESUMO Objetivo: Relatar um caso incomum de pólipo piloso (PP) oral e revisar a literatura para trazer informações epidemiológicas, clínicas e histopatológicas acerca da doença. Descrição do caso: Paciente do sexo masculino, 12 anos de idade, encaminhado ao Departamento de Estomatologia com nódulo na região posterior de linha média da língua. O paciente não soube relatar quando surgiu a lesão e se ela havia crescido desde então. O exame clínico revelou massa pedunculada, volumosa e móvel no dorso da língua, medindo aproximadamente 1,0 cm de diâmetro. A mãe do paciente relatou que ele nunca havia tido nenhum problema de saúde anterior. Foi realizada biópsia excisional e o material foi enviado para análise anatomopatológica, sendo os achados compatíveis com o diagnóstico de PP. Comentários: O pólipo piloso é uma lesão rara, especialmente na região oral. A pesquisa bibliográfica revelou apenas dez relatos de casos de PP oral, publicados entre janeiro de 1999 e janeiro de 2019, sendo observada predominância da doença em recém-nascidos do sexo feminino. Dois fatos incomuns ocorreram neste caso: tratava-se de um paciente do sexo masculino e o diagnóstico se deu aos 12 anos de idade.

Vocal Fold Polyps: Literature Review

Abstract Introduction Vocal fold polyps are one of themost frequent benign laryngeal lesions, impacting the quality of life of those affected by them, primarily the vocal production. Despite being a well-established therapy in conjunction with surgery, speech therapy alone may also be effective in treating these lesions. As such, otolaryngologists and speech therapists need updated bibliographic knowledge on the issue. Objective To describe the literature findings on vocal fold polyps that discuss prevalence, etiology, histology, physiopathology, vocal characteristics or treatment. Data Synthesis The present study is a review article based on a bibliographic search using platforms, databases and search engines, with no restrictions on means of publication, methodological quality or language. All the articles on vocal fold polyps pertaining to the object of study published in the past 15 years were included. Among the characteristics investigated, the most discussed were prevalence of men, smoking as an etiological cofactor, the possibility of histological differentiation from vocal nodules, the relationship with cover minor structural alterations, and the indication and effectiveness of different treatment options. Conclusion Despite the discrepancies found in the present literature review on vocal fold polyps, there has been a notable scientific progress in the otolaryngologic techniques and in the effectiveness of speech therapy as initial treatment, with direct and indirect techniques, corroborating the need for scientific investigation of the issue.

Sangrado y terapia hormonal en la menopausia (THM) / Bleeding during menopause hormone therapy (MHT)

La definición de sangrado ginecológico anormal durante terapia hormonal de la menopausia es aquel sangrado no programado durante el uso de la terapia. Este artículo es un pauteo que describe: 1) cuándo diagnosticar unsangrado anormal, ya que difiere según el tipo de esquema hormonal utilizado; 2) eldiagnóstico diferencial del origen del sangrado anormal; 3) los métodos de evaluación para diagnosticar el origen del sangrado. Se destacan los aspectos principales para el diagnóstico diferencial entre patología orgánica versus disrupción endometrial debida al tratamiento hormonal. Además, se describen los ajustes posibles para resolver el sangrado cuando éste se debe a disrupción del endometrio.

Abnormal bleeding related to menopausal hormone therapy is defined as unscheduled bleeding during the use of the therapy. This article outlines when to diagnose an abnormal bleeding -as this differs according to the type of hormonal scheme used-, the differential diagnosis of the origin of abnormal bleeding, and the methods of evaluation to assess the origin of the bleeding. The main aspects are highlighted on the differentiation of organic pathology versus disruption of the endometrium due to treatment. Also, treatment adjustments to resolve bleeding when it is due to disruption of the endometrium are outlined.

Doença ulcerosa péptica: realmente é possível identificá-la por meio das características da dor epigástrica? / Peptic ulcer disease: is it really possible to identify it through the characteristics of epigastric pain?

OBJETIVO: Determinar se características da dor epigástrica são capazes de identificar pacientes com doença ulcerosa péptica. MÉTODOS: Estudo caso-controle, com coleta de dados de setembro de 2014 a junho de 2016. Foram incluídos pacientes com mais de 18 anos com dispepsia que realizaram endoscopia digestiva alta ambulatorialmente. Os pacientes foram abordados antes de realizar a endoscopia digestiva alta, verificando, em suas guias, a presença de dispepsia, tendo sido convidados a responder um questionário, e, posteriormente, o prontuário de cada entrevistado foi avaliado para verificação do diagnóstico, sendo, então, divididos entre o Grupo Doença Ulcerosa Péptica (casos), com 32 pacientes, e o Grupo Controle, com 44 pacientes com dispepsia atribuída a outras causas. RESULTADOS: Dos pacientes com dispepsia não ulcerosa, 52,27% caracterizaram a dor como em queimação, sendo 47,72% moderada e que piorava com alimentação. Dentre os demais sintomas, 45,45% relataram náuseas e 25% desconforto pós-prandial, com 52,27% relatando histórico familiar negativo de doença ulcerosa péptica. Em contrapartida, dos pacientes com doença ulcerosa péptica, 53,12% referiram dor em queimação e de moderada intensidade, e 50% relataram piora com alimentação. Dentre os demais sintomas, prevaleceram também náuseas (53,12%) e desconforto pós-prandial (40,62%). A maioria (81,25%) relatou histórico familiar de doença ulcerosa péptica. Observou-se diferença estatística em dor noturna, predominando na doença ulcerosa péptica (p=0,0225) e dor em cólica na dispepsia não ulcerosa (p=0,0308), assim como na ausência de histórico familiar entre os pacientes com dispepsia não ulcerosa (p=0,0195). CONCLUSÃO: A dispepsia relacionada à doença ulcerosa péptica relaciona-se, principalmente, à piora noturna, sendo que a intensidade da dor, a relação com alimentação e os sintomas associados não auxiliaram na diferenciação da dispepsia não ulcerosa, diferentemente do que a literatura tradicionalmente informa.

To determine whether it is possible to identify Peptic Ulcer Disease through the characteristics of epigastric pain. METHODS: This is a case-control study with data collected between September 2014 and June 2016 including patients over 18 years of age with dyspepsia who underwent upper gastrointestinal endoscopy as outpatients. The patients were approached before the upper gastrointestinal endoscopy when their test requisition form indicated the presence of dyspepsia. The subjects were invited to answer a questionnaire and, afterwards, the records of all interviewees were evaluated to check for the diagnosis. Then, they were divided into a peptic ulcer disease group (cases), with 32 patients, and a control group, with 44 patients with dyspepsia from other causes. RESULTS: Among non-ulcer dyspepsia patients, 52.27% described the pain as a "burning pain", with 47.72% reporting it as moderate and aggravated by food intake. As for other symptoms, 45.45% of subjects reported nausea, and 25% reported postprandial discomfort; 52.27% had no family history of peptic ulcer disease. In contrast, 53.12% of peptic ulcer disease patients reported "burning" and moderate pain, and 50% said the pain was aggravated by eating. As for the other symptoms, nausea (53.12%) and postprandial discomfort (40.62%) prevailed; most of the patients (81.25%) had family history of peptic ulcer disease. There was a statistical difference in night pain, which was more prevalent in peptic ulcer disease (p=0.0225), and colicky pain, which was more frequent in nonulcer dyspepsia (p=0.0308), as well as absence of family history in non-ulcer dyspepsia patients (p=0.0195). CONCLUSION: Dyspepsia caused by peptic ulcer disease is mainly related to night worsening, and pain intensity, the relationship with food intake, and associated symptoms did not help differentiate nonulcer dyspepsia, differently from what the medical literature traditionally suggests.

Coriocarcinoma gástrico primario: reporte de caso / Primary gastric choriocarcinoma: case report

El coriocarcinoma gástrico primario (CGP) es un tumor extremadamente raro, altamente invasivo y de rápida diseminación hematógena. Presentamos el caso de una paciente de 57 años que inicia con cuadro de hematemesis y, progresivamente, se le suman episodios de melena, baja de peso y epigastralgia. Es derivada al Instituto Nacional de Enfermedades Neoplásicas en donde se le realizan gastroscopía y biopsia. Así, el análisis histológico reportó patrón sugestivo para CGP; el cual se confirmó al realizarle a la paciente los estudios por imágenes necesarios y llevar a cabo el análisis inmunohistoquímico para gonadotrofina coriónica humana y alfa feto proteína. Posteriormente, a la paciente se le realiza una gastrectomía radical D2 con preservación esplénica y de cola de páncreas. Lamentablemente, su evolución no fue favorable y fallece por la progresión de la enfermedad.

Primary gastric choriocarcinoma (PGC) is an extremely rare and highly invasive tumor with rapid hematogenous spread. We present the case of a 57-year-old female patient who started with hematemesis and progressive episodes of melena, weight loss and epigastralgia. It is derived from the National Institute of Neoplastic Diseases where gastroscopy and biopsy are performed. Histological analysis reported pattern suggestive of PGC; that was confirmed by immunohistochemical analysis for human chorionic gonadotrophin and fetal alpha protein. Subsequently, the patient underwent a radical D2 gastrectomy with splenic preservation and tail of the pancreas preservation. Unfortunately, her evolution was not favorable and died due to the progression of the disease.

Pólipo y/o granuloma aural en niños. Estudio prospectivo en 75 casos / Aural polyp and/or granuloma in children. A prospective study of 75 cases

En otorrinolaringología (ORL) infantil es habitual el hallazgo de pólipos y granulomas de oído en niños que consultan especialmente por otorrea de evolución prolongada. El pólipo y/o granuloma aural es una masa de carácter inflamatorio, que ocupa parte de la luz del conducto auditivo externo, generalmente pediculado, de aspecto congestivo, a veces friable y fácilmente sangrante, cuyo origen generalmente es a nivel de la mucosa del oído medio. Con el objetivo de describir las características clínicas, otológicas, bacteriológicas e histopatológicas de los pólipos y granulomas de oído diagnosticados en un servicio de ORL pediátrico se realizó un estudio prospectivo, descriptivo, observacional y longitudinal. Se estudió a la población pediátrica con diagnóstico de pólipo y/o granuloma aural en su primera consulta en el servicio de ORL del Hospital de Pediatría "Prof. Dr. Juan P. Garrahan". Se incluyeron 75 pacientes en el estudio, evaluados consecutivamente desde el 02 de diciembre 2013 y hasta 30 enero del 2015, con una edad media: 93 meses (rango 2­180). Se realizó otomicroscopía y, en los casos de granulomas y pólipos accesibles, se realizó toma de muestra para estudio bacteriológico e histopatológico y evaluaciones audiológicas y radiológicas con tomografía computarizada (TC) en los casos necesarios. Se indicó el tratamiento médico o quirúrgico adecuado a cada patología. El motivo de consulta principal fue la otorrea como único síntoma en el 81,33% de los casos y, en menor porcentaje, asociada a otros síntomas. Tiempo medio de evolución de los síntomas: 13,5 meses (rango 1-96). No se pudo extraer material en el 20% de los pacientes. Se tomaron muestras para estudio de 60/75 granulomas óticos accesibles. El informe anatomo-patológico fue: granuloma o pólipo inflamatorio en el 50%, tejido epidermoide compatible con colesteatoma en el 41,7%, tuberculosis (TBC) en 3,3%, granuloma por cuerpo extraño en 1,7%, histiocitosis de células de Langerhans (HCL) en 3,3% muestras de pólipos. Se realizó estudio bacteriológico en 57/75 casos. Se desarrollaron gérmenes en 52/57 cultivos. El 32,7% (17/52) fueron cultivos polimicrobianos. Dos casos desarrollaron Mycobacterium tuberculosis. Se observó velamiento de caja, ático o mastoides con erosión ósea en el 46,2% (24/52) de los casos evaluados con TC. Diagnóstico final: colesteatoma 39 pacientes, OMA con pólipo de Scheibe o complicada con mastoiditis 16, OMC simple granulomatosa 13, TBC 2, HCL 2, otitis externa y celulitis en conducto auditivo externo 2 y granuloma a cuerpo extraño 1. Conclusiones: es importante obtener el diagnóstico histológico y microbiológico de los pólipos aurales en niños precozmente para excluir neoplasia u otras enfermedades granulomatosas específicas y evitar cirugías que pueden provocar secuelas al no estar indicadas en el tratamiento adecuado de ciertos tumores e infecciones (AU)

In pediatric otolaryngology (ENT) ear polyps and granulomas are a common finding in children who consult especially for prolonged otorrhea. The aural polyp and/or granuloma is an inflammatory mass occupying part of the lumen of the external auditory canal. It is usually pedunculated, congestive, sometimes friable, and may bleed easily. Its origin is usually at the level of the mucosa of the middle ear. With the aim to describe the clinical, otological, bacteriological, and histopathological features of ear polyps and granulomas diagnosed in a Department of pediatric ENT, a longitudinal, prospective, descriptive, observational study was conducted. Pediatric patients diagnosed with an aural polyp and/or granuloma at the first visit at the Department of ENT of Hospital de Pediatría "Prof. Dr. Juan P. Garrahan" were studied. Seventy-five patients were included in the study, evaluated consecutively from December 2, 2013 to January 30, 2015; Mean age was 93 months (range 2 ­ 180). Otomicroscopy was performed and, in cases of accessible granulomas and polyps, a sample was taken for bacteriological and histopathological study. Audiological and radiological evaluations with computed tomography (CT scan) were performed when necessary. Appropriate medical or surgical treatment was indicated accordingly. The main reason for the consultation was otorrhea as the only symptom in 81.33% of cases and, in a lesser percentage, associated with other symptoms. Mean time from symptom onset to diagnosis: 13.5 months (range 1-96). No sample could be harvested in 20% of patients. Samples were taken for study of 60/75 accessible ear granulomas. Pathology report was: Inflammatory granuloma or polyp in 50%, epidermoid tissue compatible with cholesteatoma in 41.7%, tuberculosis (TBC) in 3.3%, granuloma due to a foreign body in 1.7%, and Langerhans cell histiocytosis (LHC) in 3.3% of the samples of polyps. Bacterial cultures, performed in 57/75 cases, were positive in 52/57. Polymicrobial microorganisms were found in 32.7% (17/52). Mycobacterium tuberculosis was found in two cases. Opacification of the antrum, attic, and mastoid cavities with bone erosion was observed in 46.2% (24/52) of the cases evaluated with CT. Final diagnosis: Cholesteatoma in 39 patients, OMA with a Scheibe polyp or complicated with mastoiditis in 16, simple granulomatous OMC in 13, TBC in 2, LHC in 2, external otitis and cellulitis in the external ear canal in 2, and granuloma due to a foreign body in 1. Conclusions: Histological and microbiological diagnosis of aural polyps in children should be obtained early to rule out neoplasia other granulomatous diseases to avoid surgery that may cause sequelae and is not the adequate management of certain tumors and infections (AU)

Revisión de la poliposis gástrica: a propósito de un caso operado por laparoscopia, con protocolo fast track / Review of gastric polyposis: about a case operated by laparoscopy, with fast track protocol

Resumen Introducción: Los pólipos gástricos suelen ser hallazgos en la endoscopia digestiva alta. Objetivo: Realizar una revisión de los pólipos gástricos más frecuentes y presentar un caso de manejo de estos con gastrectomía total laparoscópica según el protocolo fast track. Caso clínico: Se presenta el caso de un paciente hombre de 46 años, sin antecedentes mórbidos con poliposis difusa del estómago sintomática, en el que se realiza una gastrectomía total laparoscópica siguiendo el protocolo fast track, siendo dado de alta al cuarto día posoperatorio. Discusión: Los pólipos gástricos más frecuentes son los hiperplásicos, de glándula fúndica, adenomas e inflamatorios. Es fundamental obtener biopsias de estos ya que su histología comandará su manejo y pronóstico. En algunos casos, la gastrectomía total es la indicación debido a su riesgo de malignidad o sintomatología. El protocolo fast track ha demostrado ser una modalidad de manejo posoperatorio que disminuye el tiempo de estadía hospitalaria y presenta una recuperación precoz en comparación con la práctica habitual, sin comprometer la seguridad del paciente.

Introduction: Gastric polyps are commonly found incidentally on upper gastrointestinal endoscopy. Objective: Review the most common gastric polyps and present a case of symptomatic polyps managed with laparoscopic total gastrectomy following the fast track protocol. Clinical case: Patient with symptomatic diffuse gastric polyps who had a total laparoscopic gastrectomy following the fast track protocol, who is discharged at home at fourth day post-surgery. Discussion: The most common are hyperplastic polyps, fundic gland polyps, adenomas and inflammatory fibroid polyps. Is very important to obtain biopsies to assess the histology and malignant potential. In certain cases a total gastrectomy is recommended. The fast track rehabilitation protocol is a safe method to decrease hospital stay and improve recovery.

Pólipo bilateral de cuerda vocal: presentación de un caso clínico / Bilateral vocal cord polyp: case report

Los pólipos de cuerda vocal son lesiones laríngeas benignas. Se asocian a micro-traumatismos por mal uso vocal que generan remodelación de la lámina propia y el epitelio. Es más frecuente en hombres entre los veinte y cuarenta años. En la gran mayoría de los casos se presenta de manera unilateral. Si bien estas lesiones están bien documentadas en la literatura, es raro encontrar presentaciones bilaterales, por lo que su enfrentamiento y manejo puede ser discutible. Se presenta el caso de una paciente de sexo femenino de 41 años, fumadora, que consulta por disfonía de larga data. Se diagnostican pólipos bilaterales de cuerda vocal, realizando una intervención quirúrgica en un tiempo, con un resultado favorable.

Vocal cord polyps are benign Iaryngeal lesions. They are associated to micro traumatisms because ofvocal misuse, generating a remodelation of the lamina propria and the epithelium. It is more common in men between twenty and forty years of age. In the vast majority of cases it unilaterally occurs. While these are well documented injuries in the literature, it is rare to find bilateral presentations, so their confrontation and management may be debatable. We present the case of a female patient, smoker, who consulted for chronic dysphonia. Bilateral vocal cord polyps were diagnosed, performing a bilateral resection with a positive outcome.

Colonoscopy in the diagnosis of acute lower gastrointestinal bleeding / A colonoscopia no diagnóstico da hemorragia digestiva baixa aguda

Lower gastrointestinal bleeding is defined as a bleeding originated from a source distal to the Treitz ligament and the colonoscopy is well established as the diagnostic procedure of choice. Objective: To evaluate the results of colonoscopies performed to diagnose the cause of acute lower gastrointestinal bleeding in a general hospital at Mato Grosso do Sul. Material and methods: Colonoscopy procedures performed in the Endoscopy service of the Hospital Regional de Mato Grosso do Sul in those patients admitted due to an acute lower gastrointestinal bleeding from January 2014 to December 2015 were analyzed retrospectively. The studied variables were age, gender, diagnosis and localization of the lesion. Results: The mean age was 66 years, and there was a little predominance of the male gender. Diverticular disease was the main cause of lower gastrointestinal bleeding in this study, followed by cancer, inflammatory gastrointestinal disease, polyps, and angiodysplasia. Conclusion: The colonoscopy showed to be an effective diagnostic method in the case of acute lower gastrointestinal bleeding and a good therapeutic tool in the case of diverticular disease and angiodysplasia.

Hemorragia digestiva baixa é definida como sangramento originado de uma fonte distal ao ligamento de Treitz e a colonoscopia esta bem estabelecida como o seu procedimento diagnóstico de escolha. Objetivo: Avaliar os resultados das colonoscopias realizadas para elucidação diagnóstica dos casos de Hemorragia digestiva baixa aguda em um Hospital Geral de Mato Grosso do Sul. Materiais e métodos: Foram analisadas, de forma retrospectiva, as colonoscopias realizadas nos pacientes internados devido à hemorragia digestiva baixa aguda, no período de janeiro de 2014 a dezembro de 2015, no serviço de endoscopia digestiva do Hospital Regional de Mato Grosso do Sul. As variáveis estudadas foram a idade, sexo, diagnóstico e localização da lesão. Resultados: A média de idade foi de 66 anos, com uma discreta predominância do sexo masculino. A doença diverticular foi a principal causa de hemorragia digestiva baixa nesse estudo, seguido de neoplasias, doença inflamatória intestinal, pólipos e angiodisplasia. Conclusão: A colonoscopia mostrou-se como método efetivo no diagnóstico dos casos de Hemorragia digestiva baixa aguda e como uma boa ferramenta terapêutica também nos casos de angiodisplasia.

Pólipos endometriales: Actualización en diagnóstico y tratamiento / Endometrial polyps: update on diagnosis and treatment

ANTECEDENTES: Los pólipos endometriales son protrusiones nodulares benignas de la superficie endometrial con características clínico-patológicas propias y de origen desconocido. Su prevalencia es alta, especialmente en pacientes con sangrado uterino anormal, se asocia a infertilidad y a cáncer de endometrio, lo que se traduce en que se trata de una patología muy importante en el quehacer ginecológico habitual. OBJETIVOS: Revisar la patogenia, actualizar y evaluar los métodos diagnósticos, y definir las mejores opciones terapéuticas de esta frecuente patología. MÉTODO: Revisión sistemática de la literatura publicada en el tema, mediante búsqueda en base de datos Pub Med. RESULTADOS: La patogenia es aun desconocida, es una patología muy heterogénea y no hay causa única, se han reportado varios hallazgos relacionados con alteraciones genéticas. La ultrasonografía de alta definición, la hidrosonografia y la histeroscopia son el estándar actual en el diagnóstico. Las opciones terapéuticas se extienden desde la observación y seguimiento con imágenes, hasta la histerectomía con biopsia contemporánea, siendo la histeroscopia quirúrgica el método más costo efectivo. CONCLUSIÓN: La patogenia de los pólipos endometriales se encuentra actualmente en revisión, no hay ninguna teoría que explique la génesis de todos los pólipos. La ultrasonografía con contraste y la histeroscopia constituyen el estándar en el diagnóstico. En el tratamiento, la indicación es la cirugía histeroscopica y en especial la resección electroquirúrgica, que permite una extracción completa del pólipo bajo visión directa, con enfoque diagnóstico y terapéutico, con riesgos bajos y recurrencia mínima.

BACKGROUND: Endometrial polyps are benign nodular protrusions of the endometrial surface with clinical and pathological features of unknown origin. Its prevalence is high, especially in patients with abnormal uterine bleeding, it is associated with infertility and endometrial cancer, what constitutes a common and important disease. AIMS: To review the pathogenesis, to update and evaluate diagnostic methods, and to define the best treatment options for this common condition. METHODS: A systematic review of the published literature on the subject by searching PubMed database. RESULTS: The pathogenesis is still unknown, it is a very heterogeneous disease and there is no single cause, there have been several findings related to genetic alterations. High definition ultrasonography, the hidrosonography and hysteroscopy are the current standard in diagnosis. Therapeutic options range from observation and follow up with images to the hysterectomy using contemporary biopsy, surgical hysteroscopy being the most cost effective method. CONCLUSION: The pathogenesis of endometrial polyps are currently under review, there is no theory to explain the genesis of all polyps. Contrast ultrasonography and hysteroscopy are standard in the diagnosis. In the treatment, the indication is histeroscopy surgery and especially electrosurgical resection, which allows complete removal of polyps, diagnostic and therapeutic approach, with low risk and low recurrence.

Intravitreal Anti-vascular Endothelial Growth Factor for Treating Polypoidal Choroidal Vasculopathy with Grape-like Polyp Clusters

PURPOSE: To evaluate 12-month outcomes of anti-vascular endothelial growth factor (VEGF) therapy for polypoidal choroidal vasculopathy (PCV) with grape-like polyp clusters. METHODS: This retrospective observational study included 23 eyes of 23 patients who were newly diagnosed with PCV with grape-like polyp clusters, and who were subsequently treated with anti-VEGF monotherapy. The study compares the best-corrected visual acuity (BCVA) of the patients at diagnosis, at 3 months, and at 12 months after diagnosis. In addition, 12-month changes in BCVA values were compared between cases with subfoveal or juxtafoveal polyps and cases with extrafoveal polyps. RESULTS: The baseline, 3-month, and 12-month logarithm of the minimal angle of resolution BCVA was 0.62 ± 0.35, 0.50 ± 0.43, and 0.58 ± 0.48, respectively. Compared to the baseline, patient BCVA was not significantly different at 12 months after diagnosis (p = 0.764). Six eyes (26.1%) gained ≥0.2 logarithm of the minimal angle of resolution BCVA. In cases with subfoveal or juxtafoveal polyps, BCVA values at baseline and at 12 months after diagnosis were 0.66 ± 0.37 and 0.69 ± 0.53, respectively. In cases with extrafoveal polyps, the values were 0.54 ± 0.33 and 0.37 ± 0.31, respectively. Changes in BCVA values were significantly different between the two groups (p = 0.023). CONCLUSIONS: Although anti-VEGF therapy has favorable short-term efficacy for treating PCV with grape-like polyp clusters, long-term visual improvements are generally limited in the majority of afflicted eyes. The presence of subfoveal or juxtafoveal polyps may suggest unfavorable treatment outcomes.

Intravitreal Anti-vascular Endothelial Growth Factor for Newly Diagnosed Symptomatic Polypoidal Choroidal Vasculopathy with Extrafoveal Polyps

PURPOSE: To evaluate the 12-month outcome of anti-vascular endothelial growth factor (VEGF) treatment for extrafoveal polypoidal choroidal vasculopathy (PCV). METHODS: This retrospective observational study included 32 eyes of 32 patients newly diagnosed with extrafoveal PCV (polyps located more than 500 microm from the center of the fovea). Patients were treated with intravitreal ranibizumab, bevacizumab, or both. The best-corrected visual acuity (BCVA) and central foveal thickness (CFT) at diagnosis and at 12 months were compared. Eyes were divided into two groups according to the presence of submacular hemorrhage. The BCVA in each group was compared at baseline and at 12 months. RESULTS: During the 12-month study period, patients received an average of 4.0 +/- 1.1 anti-VEGF injections. The BCVA at baseline, three-month post-diagnosis, and 12-month post-diagnosis was 0.59 +/- 0.40, 0.34 +/- 0.38, and 0.38 +/- 0.38, respectively. The BCVA at 12 months was significantly better than the baseline value (p = 0.002). The CFT at baseline, three-month, and 12-month post-diagnosis was 477.1 +/- 194.2 microm, 214.5 +/- 108.8 microm, and 229.8 +/- 106.1 microm, respectively. The CFT at 12 months was significantly lower than the baseline value (p < 0.001). A significant improvement in BCVA was noted in eyes with and without submacular hemorrhage (n = 13, p = 0.032 and n = 19, p = 0.007, respectively). CONCLUSIONS: Anti-VEGF therapy was beneficial in extrafoveal PCV, regardless of the presence of submacular hemorrhage.

Tumores benignos de vulva: revisión y caso clínico de acrocordón / Benign tumors of vulva: review and case report of achrocordon

La región vulvovaginal es una zona muy compleja por todos los elementos que la conforma y puede ser origen de un gran número de tumores benignos y en menor frecuencia de tumores malignos. En las últimas décadas, los tumores vulvovaginales han tenido un avance significativo en cuanto a su diagnóstico y tratamiento, dado por las aportaciones de la biología celular y molecular. El presente artículo pretende ser una referencia práctica para el diagnóstico clínico e histopatológico de estos tumores benignos así como en el tratamiento ambulatorio de algunos de ellos y su vigilancia.

The vulvovaginal region is a very complex area because of its anatomy and the fact that it can be source of a large number of benign tumors and less frequent malignant tumors. In recent decades, there have been significant gains in the diagnosis and treatment of vulvovaginal tumors, thanks to the contributions of cellular and molecular biology. The purpose of this review article is to serve as a practical reference for clinical and pathological diagnosis as well as in the outpatient treatment and monitoring of these benign tumors.

Pólipo endometrial, una causa infrecuente de sangrado genital anormal en la adolescencia / Endometrial polyp, a rare cause of abnormal genital bleeding in adolescence

Antecedentes: El sangrado genital anormal es una causa frecuente de consulta en la adolescencia. En este período, la principal causa de sangrado es la metrorragia asociada a ciclos anovulatorios producto de la inmadurez del eje hipotálamo-hipofisario-gonadal. Dentro de las causas infrecuentes de sangrado genital anormal en ese período está el pólipo endometrial. Caso clínico: Presentamos el caso de una niña de 13 años cuya causa de sangrado correspondió a un pólipo endometrial, sospechado por ultrasonografía, resecado mediante histeroscopia y confirmado mediante estudio histológico. Discusión: Pese a su baja incidencia, los pólipos endometriales deben ser considerados como parte del diagnóstico diferencial en adolescentes que consultan por trastorno menstrual, particularmente en aquellos casos sin respuesta a la terapia hormonal y donde la ultrasonografía muestra engrosamiento endometrial.

Background: Abnormal genital bleeding is a common cause of medical consultation in patients during adolescence. In this period, the main cause of genital bleeding is metrorrhagia in relation to anovulatory cycles due to immaturity of hypothalamus- pituitary-gonadal axis. Among the uncommon causes of bleeding at this age is the endometrial polyp. Case report: We report a 13 year old girl with abnormal uterine bleeding due to endometrial polyp, suspected during a pelvic ultrasound, removed by hysteroscopy, and confirmed by histological analysis. Discussion: Despite its low incidence, endometrial polyps should be included in the differential diagnosis of adolescents presenting menstrual disorders, particularly in those with no response to hormonal therapy and endometrial thickness in ultrasound.

Diagnóstico clínico e análise histológica de nódulos e pólipos vocais / Clinical diagnosis and histological analysis of vocal nodules and polyps

Estudos atuais enfatizam a importância da correlação clínico-histológica nas afecções laríngeas. OBJETIVO: Comparar o diagnóstico otorrinolaringológico com anatomopatológico de 132 espécimes cirúrgicos, provenientes de 119 pacientes operados de nódulos e pólipos vocais. MÉTODO: Estudo retrospectivo. Foram levantados os blocos de parafina correspondentes às lesões dos pacientes operados. Realizaram-se novos cortes histológicos, totalizando 396 novas lâminas, divididas em três grupos: hematoxilina e eosina, tricômico de Gomori e PAS. Foram analisados os parâmetros histológicos: epitélio, lâmina própria, membrana basal, alterações vasculares. Foram comparados os diagnósticos anatomopatológico e laringológico. Realizou-se análise estatística verificando os aspectos histológicos predominantes em cada lesão. RESULTADOS: Houve concordância entre o diagnóstico clínico e anatomopatológico em 123 (93,18%) lesões das 132 analisadas (42,42% nódulos e 50,76% pólipos). Nos parâmetros histológicos, verificou-se: alterações epiteliais como hiperplasia nos nódulos (82,14%) e atrofia nos pólipos (31,34%). Lâmina própria: edema nos pólipos (71,43%), fibrose nos nódulos (57,14%). Membrana basal: espessada nos nódulos (100%), fina/sem alteração nos pólipos (100%). Houve predomínio das alterações vasculares nos pólipos. CONCLUSÃO: Notou-se elevada correlação entre o diagnóstico otorrinolaringológico e o anatomopatológico. Histopatologicamente, nódulos apresentaram-se com alterações predominantemente epiteliais, fibrose na lâmina própria e espessamento da membrana basal, enquanto os pólipos por alterações estritamente de lâmina própria e aspectos vasculares.

Recent studies emphasize the importance of the clinical-histology correlation in laryngeal pathologies. OBJECTIVE: To compare the ENT diagnosis with the pathology diagnosis one of 132 surgical specimens, from 119 patients with vocal nodules and polyps. METHOD: Retrospective study. We investigated the paraffin blocks corresponding to the lesions of the operated patients. We made new histology cross-sections, totaling 396 new slides, divided into three groups: hematoxylin and eosin, Gomori trichrome and PAS. We analyzed the following histological parameters: epithelium, lamina propria, basement membrane, vascular changes. We compared the laryngological and pathological diagnoses, and we did the statistical analysis, checking the predominant histological aspects in each lesion. RESULTS: There was an agreement between the clinical and pathological diagnoses in 123 (93.18%) of 132 lesions analyzed (42.42% nodules and 50.76% polyps). In the histological parameters we found: epithelial changes such as nodules hyperplasia (82.14%) and polyp atrophy (31.34%). Lamina propria: edema in polyps (71.43%), fibrosis in the nodules (57.14%). Basement membrane: thickened nodules (100%), thin/no change in polyps (100%). There was a predominance of vascular changes in the polyps. CONCLUSION: We found a high correlation between the ENT diagnosis and the pathology report. Histopathologically, the nodules presented with predominantly epithelial changes, lamina propria and basement membrane fibrosis, while the polyps by changes strictly on the lamina propria and vascular aspects.

Pólipos endometriais e seu risco de malignização: aspectos epidemiológicos, clínicos e imunoistoquímicos / Endometrial polyps and the risk of malignancy: epidemiological, clinical and immunohistochemical aspects

Pólipos endometriais são neoformações resultantes de uma hiperplasia focal da camada basal do endométrio associada a um hiperestímulo hormonal. Sua etiologia ainda não está bem estabelecida, não havendo consenso sobre sua história natural, seu real significado como entidade patológica e sua relação com a neoplasia endometrial. Os pólipos endometriais são a principal indicação de histeroscopia cirúrgica, sem que haja, no entanto, um protocolo definido para seu melhor manejo. Uma visão abrangente sobre essa condição pode auxiliar na escolha da conduta mais adequada. (AU)

Endometrial polyps are neoformations that result from focal hyperplasia of the endometrial basal layer associated with hormonal hyperstimulation. Their pathogenesis is still unclear, and there is no consensus on their natural history, actual relevance as pathologic entities, and relationship with endometrial neoplasia. Endometrial polyps are the most frequent indication of surgical hysteroscopy, but their optimal management remains controversial. Therefore, an overview of this condition may help choosing the most adequate treatment strategies.(AU)

Tamoxifeno y afecciones endometriales en pacientes con cáncer de mama / Tamoxifen and endometrial disease in patients with breast cancer

Los objetivos fueron evaluar la prevalencia de afecciones endometriales en pacientes tratadas con tamoxifeno (TAM) y analizar los aspectos epidemiológicos, ecográficos, histeroscópicos e histopatológicos. Desde enero de 1999 a diciembre 2008 se estudiaron 152 pacientes con cáncer de mama tratadas con TAM (20 mg/día), sintomáticas (con sangrado) o asintomáticas, pre y postmenopáusicas, incluidas en forma consecutiva. El diseño fue prospectivo y observacional. Los métodos diagnósticos usados fueron ecografía transvaginal, histeroscopía y biopsia. Las pacientes fueron seguidas durante 5 años con ecografía cada 12 meses e histeroscopia con biopsia en casos que lo justificaran. Edad: 62.76 ± 10.24 años y tiempo de tratamiento: 36.2 ± 19.9 meses. El adenocarcinoma se observó en 3/87 (3.45%) pacientes con factores de riesgo y en 1/65 (1.54%) sin ellos (RA: 1.91, IC 95% 1.88 a 1.94). Las afecciones benignas se hallaron en 148 pacientes (97.37% y los adenocarcinomas en 4 (2.63%),1 en un pólipo de aspecto benigno. Los 4 se observaron en mujeres postmenopáusicas (2 asintomáticas) con grosor endometrial igual o mayor a 16 mm. El riesgo de cáncer fue significativamente mayor en sintomáticas (2.36 versus 0.42 en asintomáticas). Tres adenocarcinomas se detectaron entre 24 y 48 meses del tratamiento. Recomendamos un seguimiento con ecografía transvaginal de las pacientes asintomáticas, resección de los pólipos evaluando factores de riesgo y tiempo de exposición, en especial luego de los 24 meses. Consideramos aceptable un cut-off = 10 mm en el grosor del endometrio en postmenopáusicas asintomáticas para realizar histeroscopía y biopsia.

The objectives were to evaluate prevalence of endometrial disease in patients treated with tamoxifen (TAM) and analyze the epidemiological, sonographic, hysteroscopic and histopathological findings. From January 1999 to December 2008, 152 breast cancer patients treated with TAM (20 mg/day), symptomatic (with bleeding) or asymptomatic, pre- and postmenopausal, were included consecutively in a prospective and observational follow-up study Diagnostic methods were (TV) transvaginal ultrasound, hysteroscopy and curettage biopsy. TV ultrasound was performed every 12 months for 12 to 60 months. The patients´ age were 62.76 years ± 10.24 the TAM-time: 36.24 ± 19. Adenocarcinoma was observed in 3/87 patients (3.45%) with risk factors and in 1/65 (1.54%) without them (RA 1.91, IC 95% 1.88-1.94). We found benign disease in 148 patients (97.37%) and adenocarcinomas in 4 (2.63%), one within a polyp. The 4 adenocarcinomas were detected in postmenopausal women (2 asymptomatic) with endometrial thicknesses equal or greater than 16 mm. The cancer risk was significantly increased in symptomatic (2.36 versus 0.42 in asymptomatic). Three adenocarcinomas were observed between 24 and 48 months of treatment. In conclusion, we suggest an adequate transvaginal ultrasound monitoring of asymptomatic patients treated with TAM, with removal of polyps, because atypia can be present hidden within, considerin risk factors and exposure time. We suggest as an acceptable cut-off = 10 mm in asymptomatic postmenopausal patients.
