RESUMO

La hidradenitis supurativa (HS) es una enfermedad inflamatoria crónica de la piel que afecta a las glándulas sudoríparas apocrinas y causa nódulos inflamatorios, abscesos y fistulas dolorosas en áreas como las axilas, la ingle y los glúteos. Su impacto en la calidad de vida de los pacientes es significativo. La HS afecta al 1- 4% de la población mundial y se asocia con factores como el sobrepeso, el tabaquismo y antecedentes familiares. Su patogenia es compleja, involucrando inflamación y disfunción inmunológica. Su diagnóstico y tratamiento son desafiantes, especialmente en casos graves. El diagnóstico se basa en la presentación clínica, que a menudo se confunde con otras afecciones cutáneas. Se clasifica en etapas de Hurley según la gravedad. El tratamiento se centra en controlar los síntomas y prevenir recurrencias. Incluye educación del paciente, tratamiento médico y cirugía. La elección de la terapia antibiótica depende de la severidad y las cepas bacterianas presentes. Para casos graves, se investigan terapias biológicas. La cirugía, como la escisión simple o con injertos de piel, es efectiva en el control de la enfermedad. Presentamos un caso clínico de un paciente con HS, revisamos la epidemiología, etiopatogenia y su diagnóstico acompañado de las opciones terapéuticas existentes

Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease that affects the apocrine sweat glands and causes inflammatory nodules, abscesses, and painful fistulas in areas such as the armpits, groin, and buttocks. Its impact on patients' quality of life is significant. HS affects 1-4% of the world's population and is associated with factors such as overweight, smoking, and family history. Its pathogenesis is complex, involving inflammation and immune dysfunction. Its diagnosis and treatment are challenging, especially in severe cases. Diagnosis is based on clinical presentation, which is often confused with other skin conditions. It is classified into Hurley stages based on severity. Treatment focuses on controlling symptoms and preventing recurrences. Includes patient education, medical treatment and surgery. The choice of antibiotic therapy depends on the severity and the bacterial strains present. For severe cases, biological therapies are investigated. Surgery, such as simple excision or skin grafts, is effective in controlling the disease. We present a clinical case of a patient with HS, we review the epidemiology, etiopathogenesis and its diagnosis accompanied by the existing therapeutic options.

RESUMO

BACKGROUND: The antibody Ki-67 is a reliable and easy tool to accurately assess the growth fraction of neoplasms in humans and animals, and it has been used to predict the clinical outcome. Therefore, the aim of the present study was to investigate the immunohistochemical expression pattern of Ki-67 in normal and neoplastic perianal glands of dogs to evaluate the possible use of this proliferation marker as an ancillary method of perianal tumor diagnosis. We studied 42 cases of perianal gland neoplasms including adenomas (n = 15), epitheliomas (n = 15), and carcinomas (n = 12). As controls, 13 tissue samples from normal perianal glands were used. A Ki-67 index was established by a computer-assisted image analysis and compared with manual counting. RESULTS: Out of the 42 cases of perianal gland neoplasms, 34 were from males and eight from females. Recurrence was reported in 14 cases, being higher (8/12) in carcinomas. Immunostaining for Ki-67 revealed that the carcinomas showed a higher proliferation rate (9.87%) compared to groups of epitheliomas (2.66%) and adenomas (0.36%). For adenomas and epitheliomas of the perianal glands the computer-assisted counting and the manual counting gave similar results; however, only the computer-assisted image analysis was efficient to predict the perianal gland carcinoma recurrence. CONCLUSION: Since there were significant differences in the number of Ki-67-positive nuclei, this marker proved to be effective in helping the classification of perianal gland neoplasms and to refine the diagnosis criteria, especially in those samples with high variation in morphology/area. Also, higher Ki-67 index is related to recurrence in cases of perianal gland carcinomas. Further, the computer-assisted image analysis proved to be a fast and reliable method to assess the Ki-67 index in perianal gland neoplasms.

RESUMO

Introducción: La hidrosadenitis supurada (HS) es una enfermedad inflamatoria crónica que compromete las glándulas sudoríparas apócrinas, comenzando por la oclusión de los folículos pilosos. Puede localizarse en axilas, ingle, periné, periano y glúteos. Fue descripta en 1.839, es infrecuente y afecta a1 c/300-600 adultos. De acuerdo a sus características y estadio puede ser tratada médicamente o en forma quirúrgica. Objetivo: Comunicación del tratamiento quirúrgico realizado a pacientes portadores de HS localizada en la región glútea y perianal. Diseño: Trabajo descriptivo, retrospectivo y multicéntrico. Lugar de aplicación: Hosp. Santa María Magdalena de Magdalena, Hosp. HIGA San Martin de La Plata y práctica privada. Pacientes y métodos: Se analizan los resultados del tratamiento quirúrgico realizado a 7 pacientes que fueron tratados entre los años 2001 y 2011, que presentaban HS supurada glútea y perianal, con una edad promedio de 35,4 y un rango de 23 a 56. Cuatro de ellos con estadio II de Hurley a los cuales se les realizó marsupialización y drenaje y 3 con estadio III extirpación e injertos diferidos con piel del mismo paciente y una variante de injerto de piel porcina liofilizada que aceleró el tiempo de regeneración. Resultados: No se observó enfermedad de Crohn o carcinoma de células escamosas. De los 4 que fueron tratados con marsupialización, 2 evolucionaron favorablemente y fueron controlados durante 3 y 6 años respectivamente. El resto de ellos tuvieron recidivas a los 4 y 8 meses respectivamente, siendo tratados de la misma forma. Solamente 1 permanece en control desde hace tres años. Los 3 con extirpaciones e injertos diferidos son controlados en la actualidad sin presentar nuevas alteraciones, con un periodo de evolución de 5, 3 y 2 años respectivamente. No se realizaron colostomías de derivación. Conclusiones: Los métodos conservadores de tratamiento tienen poco efecto cuando la HS glútea y perianal es extensa...


Introduction: The hidrosadenitis suppurativa (HS) is a chronic inflammatory disease that affects the apocrine sweat glands. This condition occludes the hair follicles and it can be found in the armpits, the groin, the perineum, the perianal area and the gluteus. It was first described in 1839 and it is a rare disease that affects 1 among 300-600 adults. Due to the stage and the features of the disease, it can be treated either with medication or with surgery. Purpose: The aim of this study is to report the surgical treatment carried out on patients suffering from HS in the perianal area and the gluteus. Layout: This is a descriptive, retrospective and multicentre study. Place: This study was carried out in the 'Hospital Santa María Magdalena', Magdalena, in the 1 Hospital HIGA San Martín, La Plata and in private practice. Patients and Methods: The results of the surgical treatment carried out on 7 patients who suffered from HS in the perianal area and the gluteus during the years 2001 and 2011 are analyzed. Those patients were 23-56 years old on average 35.4. Marsupialization and drainage was carried out on 4 patients who were in Hurley stage II. Surgical excisions and skin grafts stage III with the patient's own skin and lyophilized pigskin that speeded the time of regeneration were done to 3 patients. Results: Crohn's Disease or squamous cell carcinoma was not observed. 2 of the 4 patients who were treated with marsupialization recovered favorably and they were monitored during 3 and 6 years. The rest of the patients had recurrences within a period of 4 and 8 months. Only 1 patient has still been monitored for the last three years. The 3 patients who had excisions and skin grafts are monitored at present and they do not show alterations within a period of evolution of 5,3 and 2 years. No colostomy was perfonned. Conclusion: The traditional methods do not show useful results when the HS in the perianal area and the gluteus is extensive...

RESUMO

El hidradenoma papilífero es una neoplasia benigna, quística y papilar, poco frecuente que por lo general aparece en la vulva, aunque también se ha descrito en otras zonas. Presentamos el caso de una mujer de 74 años con uno localizado en región perianal, cuyo diagnóstico clínico inicial fue sarcoma de Kaposi. El interés de este informe radica en recalcar que esta afección puede aparecer en una zona diferente a la vulva, para evitar diagnósticos erróneos...


Papillary hidradenoma is a rare benign neoplasm characterized by the presence of cystic and papillary structures that usually occurs on the vulva but has also been described in other locations. We report the case of a 74 year-old woman with a perianal papillary hidradenoma. An initial diagnosis of Kaposi´s sarcoma was made. In order to prevent mistaken diagnoses, this report aims to emphasize this lesion is not limited to the vulva and may appear in other locations...

RESUMO

Neoplasms in the perianal region are frequently diagnosed in dogs. The aetiology is unknown, and most of them are benign. In this study, 240 neoplasms of the perianal glands of dogs were retrieved from the Department of Pathology archives of the Faculty of Veterinary Medicine and Zootechny of University of São Paulo (FMVZ/USP), from 1984 to 2004. All 240 cases were re-examined by two pathologists. Nine cases (4%) were diagnosed as hyperplasia, 49 (20%) as group I adenoma, 81 (34%) were classified as moderately differentiated adenomas of the group II, 46 (19%) were poorly differentiated adenomas of group II, 48 (20%) were carcinoma of the group III according to the classification proposed by Berrocal, and 7 (13%) were other kind of tumours. Males over 8 years of age were predominantly affected. Cell proliferation was quantified by counting proliferating cell nuclear antigen (PCNA) positive nuclei, and apoptosis was quantified by counting fluorescent eosin-stained apoptotic corpuscles (AC) in normal tissue, hyperplasia and in different histologic types of neoplasia of these glands. A parallel pattern of increase in both parameters (cell proliferation and apoptosis) was obtained. The net growth index (NGI), represents how much a cell population is proliferating or dying and was achieved by dividing the mean PCNA count in 1000 cells by the mean AC stain count in 1000 cells. NGI was different between hyperplasia and neoplasia; group I adenomas have a much higher potential of growth, and NGI decreases from benign towards malignant lesions. These results show up the importance of studying cell proliferation and apoptosis to understand the carcinogenesis of dog perianal gland.

RESUMO

The femoral or cloacal region of many species of lizards and amphisbaenians exhibits epidermal glands. The pores of these glands are plugged with holocrine solid secretions that serve as semiochemical sources. Many authors assume that these glands are mainly associated with reproduction and demarcation of territory. The structure of precloacal glands in Amphisbaena alba was previously studied by Antoniazzi et al. (Zoomorphology 113:199-203, 1993; J. Morphol. 221:101-109, 1994). These authors suggested that as the animal moves inside tunnels, the secretion plugs are abraded against the substrate, releasing a secretion trail. Some aspects of the plug were difficult to interpret in fine sections due to the dense and brittle nature of the plug. The morphology of the trail, and the manner of deposition on the substrate, have never been reported. This study presents a primarily scanning electron microscopic description of A. alba precloacal glands and of the secretion plugs. It also demonstrates experimentally the formation of the trail and its fine morphology. The results show that when the plugs scrape against the substrate, their constitution helps them to fragment into tiny pieces, which are spread on the ground, thus forming a trail. Each one of the fragments corresponds to a secretion granule of the precloacal gland's secretory cells. In this way, the trail might have an extensive area for volatilization of semiochemicals, constituting an efficient means of intraspecific communication inside the tunnels.

RESUMO

Opossums (Didelphis marsupialis) captured in intensely urbanized areas of the city of Caracas, Venezuela, were found infected with Trypanosoma cruzi. The developmental cycle of trypomastigote-epimastigote-metacyclic infective trypomastigote, usually occurring in the intestine of the triatomine vector, was taking place in the anal odoriferous glands of the opossums. Material from the glands, inoculated in young, healthy opossums and white mice by different routes, subcutaneously, intraperitoneally, orally, and into the eye, induced T. cruzi infections in all animals. Parasitemia, invasion of cardiac and skeletal muscle, and intracellular multiplication of amastigotes were observed. Inoculation of metacyclics from anal glands, cultured in LIT medium, gave equivalent results. All opossums survived: all mice died. Excreta of opossums may thus transmit Chagas' disease by contamination, even in urban areas where insect vectors are not present.

RESUMO

Antecedentes: Las fístulas anorrectales ponen a prueba la experiencia de los cirujanos del colon y recto. Objetivo: Este artículo de revisión se realizó para discutir los avances más recientes en el diagnóstico y tratamiento de las fístulas anales complejas. Resultados: Las fallas en el tratamiento de las fístulas anorrectales pueden ser minimizadas mediante el conocimiento completo de la anatomía anorrectal y de los múltiples trayectos que pueden ocacionar las fístulas. Su complejidad está determinada por su tipo, especialmente con relación al aparato esfinteriano, que obliga a extremar el cuidado para su identificación correcta y la diferenciación de su origén. La planeación del tratamiento debe individualizarse a cada paciente que las padece. Conclusiones: El papel de las diferentes alternativas quirúrgicas dependerá de las características y relaciones del trayecto fistuloso y el esfínter

RESUMO

We report our experience with 8 women with perineal endometriosis managed in a period of 20 years. All were multiparae women presenting with cyclical perineal painful masses related to menstrual periods. Symptomatology started 6 months to 16 years after last delivery. Three patients had partial involvement of the anal sphincter. The endometriosis area was locally resected in all women. There were no complications and no problems with anal continence. Two patients had local recurrences. The different lapses between delivery and symptomatic presentation can be related to the amount of endometrial basal cells omplantes in the episiotomy. The treatment is always surgical. All endometrial implants must be resected and sphincteric structures must be repaired posteriorly

RESUMO

De 87 gambás, didelphis albiventris, capturados na regiäo de Bambuí (MG), 32 (36,7%) estavam infectados pelo Trypanosoma cruzi. Os índices de infecçäo foram 34,9%, 81,8% e 7,7%, respectivamente, para animais capturados em ambiente silvestre, peridomiciliar rural e periodomiciliar urbano. Em 20 gambás infectados as glândulas anais foram examinadas repetidamente e apenas um (5%) animal (GA09) apresentou exame positivo. Foram positivos 7 dos 17 exames a fresco da secreçäo glandular desta animal ao longo de 18 meses. Material destas glândulas produziu parasitemia patente em gambás e infecçäo subpatente em camundongos. A análise isoenzimática realizada com amostras de T. cruzi do GA09, obtidas via hemocultura, xenodiagnóstico e glândulas anais demonstraram pertencerem rigorosamente ao mesmo Zimodema semelhante ao Zimodema Z1. As observaçöes mostram que a infecçäo das glândulas anias pelo T. cruzi em gambás naturalmente infectados da regiäo de Bambuí é baixa

RESUMO

Foram estudados os aspectos morfológicos das glândulas perianais da cuíca Philander opossum: Estes marsupiais apresentam dois pares de glândulas perianais situadas respectivamente à direita e à esquerda do ânus. Cada par está formado por uma glândula lateral e outra medial. Estas glândulas estäo alojadas na fossa ísquio-retal, sob a pele da regiäo perianal, sendo a glândula medial de coloraçäo perolácea e menor que a glândula lateral, que é de coloraçäo ocre. Cada uma destas glândulas está formada pela associaçäo de vários lóbulos interligados e envolvidos pela mesma cápsula fibro-muscular. Os ductos menores da glândula medial se reúnem formando um ducto principal único antes destes emergir na superfície da glândula. Os ductos menores da glândula lateral emergem separados na sua superfície, indo se reunir mais à frente, formando o ducto principal desta glândula. Os ductos principais de ambas as glândulas correm paralelos até próximo ao ânus, onde se fundem em um ducto comum que se abre na fosseta anal, distalmente à linha pectinada. O epitélio secretor destas glândulas apresenta características de secreçäo holócrina

RESUMO

Epimastigotes were found multiplying in the anal glands and in hemocultures of an opossum; rare metacyclics were seen in the cultures. The flagellate is possibly T. (Megatrypanum) freitasi Rego, Magalhães & Siqueira, 1957, but its final identification is still pending.
