RESUMO
This work presents the isolation of endophytic fungi from the leaves of Campomanesia adamantium (Cambess.) O. Berg (Myrtaceae), a native species found in Brazil and popularly known as "guabiroba-do-campo", with abundant distribution in the Brazilian Cerrado. It has been popularly used for its anti-rheumatic, anti-inflammatory, antidiarrheal, blood cholesterol-reducing, urinary antiseptic, and depurative properties. Theese fungi are microorganisms that live inside higher plants, at least for a period of their life cycle, occupying the intercellular spaces of plant tissues such as leaves and stems. These fungi are harmless to the host plant, and their secondary metabolites promote protection, regulate growth, combat bacteria, viruses, and fungi, and promote resistance to abiotic stress, as well as insecticidal effects. Endophytic fungi associated with the leaves of C. adamantium were isolated using the culture medium isolation technique. After growth, the fungi were divided into groups based on morphotypes. Fungal genomic DNA was extracted, and a polymerase chain reaction (PCR) was conducted to amplify the ITS1-5.8S-ITS2 regions of rRNA, and the nucleotide sequences obtained were compared with those available in the GenBank database for molecular identification of the isolates. The phylogenetic tree was constructed using MEGA 11 software. The results showed representatives of the Ascomycota phylum, and it was possible to identify at the genus level 18 fungi of the genera Colletotrichum, Diaporthe, Epicoccum, and Neofusicoccum.

Endometriosis is a common and challenging condition of reproductive-aged women that is defined as the presence of endometrial-like tissue outside the uterine cavity. Despite its prevalence, there is still no effective therapeutics; so we aim to evaluate the ellagic acid (EA) effect on the most relevant aspects that are known to be altered in endometriosis. Endometrial primary cultures from women with and without endometriosis and endometrial cell lines were incubated with EA (50 and 100 µM) for 24 and 48 h. The results demonstrated that EA arrests an endometrial stromal cell cycle on the G2/M phase, after 48 h. In addition, 100 µM EA treatment significantly decreased ECC-1 cell migration at 20 h and T-HESC cell migration at 10 h and 20 h, while 50 µM EA significantly decreased T-HESC cell migration at 20 h. On the other hand, we proved that the treatment with EA for 24 h reduces T-HESC and ECC-1 adhesion to plastic. However, we did not find an effect of EA on cell proliferation. EA has an inhibitory effect on endometrial cell adhesion, migration and cell cycle progression in vitro. These highlight the idea to investigate natural compounds as novel and promising candidates for therapeutic treatment of endometriosis.

PURPOSE: Metronomic oral vinorelbine (MOV) could be a treatment option for unfit patients with advanced non-small cell lung cancer (NSCLC) based on its safety profile and high patient compliance. METHODS: We retrospectively collected data on 270 patients [median age 76 (range 48-92) years, M/F 204/66, PS 0 (27)/1 (110)/≥ 2 (133), median of 3 serious comorbidities] with stage IIIB-IV NSCLC treated with MOV as first (T1) (67%), second (T2) (19%) or subsequent (T3) (14%) line. Schedules consisted of vinorelbine 50 mg (138), 40 mg (68) or 30 mg (64) three times a week continuously. RESULTS: Patients received an overall median of 6 (range 1-25) cycles with a total of 1253 cycles delivered. The overall response rate was 17.8% with 46 partial and 2 complete responses and 119 patients (44.1%) experienced stable disease > 12 weeks with an overall disease control rate of 61.9%. Median overall time to progression was 5 (range 1-21) months [T1 7 (1-21), T2 5.5 (1-19) and T3 4 (1-19) months] and median overall survival 9 (range 1-36) months [T1 10 (1-31), T2 8 (1-36) and T3 6.5 (2-29) months]. Treatment was extremely well tolerated with 2% (25/1253) G3/4 toxicity (mainly G3 fatigue and anemia) and no toxic deaths. We observed the longer OS 14 (range 7-36) months in a subset of squamous NSCLC patients receiving immunotherapy after metronomic oral vinorelbine. CONCLUSION: We confirmed MOV as an extremely safe treatment in a large real world population of advanced NSCLC with an interesting activity mainly consisting of long-term disease stabilization. We speculate the possibility of a synergistic effect with subsequent immunotherapy.

STUDY QUESTION: Can resveratrol and epigallocatechin-3-gallate (EGCG) inhibit the growth and survival of endometriotic-like lesions in vivo in a BALB/c model of endometriosis, and in vitro in primary cultures of human endometrial epithelial cells (EECs)? SUMMARY ANSWER: Resveratrol and EGCG exerted a potent inhibitory effect on the development of endometriosis in a BALB/c murine model and on the survival of EECs. WHAT IS KNOWN ALREADY: Endometriosis is a common condition associated with infertility and pelvic pain in women of reproductive age. Resveratrol and EGCG are two polyphenols with anticarcinogenic and antioxidant properties that have been proposed as natural therapies to treat endometriosis. STUDY DESIGN, SIZE, DURATION: Fifty-six 2-month-old female BALB/c mice underwent surgical induction of endometriosis. Treatments with resveratrol or EGCG started 15 days post-surgery and continued for 4 weeks. Human biopsies were taken with a metal Novak curette from the posterior uterine wall from 16 patients with untreated endometriosis and 15 controls who underwent diagnostic laparoscopy for infertility. MATERIALS, SETTING, METHODS: After the treatments, animals were sacrificed and lesions were counted, measured, excised and fixed. Immunohistochemistry for proliferating cell nuclear antigen and CD34 was performed for cell proliferation and vascularization assessment in the lesions. The terminal deoxynucleotidyl transferase (TdT)-mediated dUTP nick-end labeling (TUNEL) technique was performed for apoptosis evaluation. Peritoneal fluid was collected to analyze vascular endothelial growth factor levels. Human EECs were purified from proliferative-phase endometrial biopsies and cultured. The effect of both polyphenols on cell proliferation was determined by a colorimetric assay using the CellTiter 96®AQueous One Solution Cell Proliferation Assay kit and on apoptosis by the TUNEL technique, using an In Situ Cell Death Detection Kit with Fluorescein. MAIN RESULTS: In the mouse model, both treatments significantly reduced the mean number (P < 0.05 versus control) and the volume of established lesions (P < 0.05 versus control). Treatments consistently statistically significantly diminished cell proliferation (resveratrol P < 0.01 and EGCG P < 0.05, versus control), reduced vascular density (resveratrol P < 0.01 and EGCG P < 0.001, versus control) and increased apoptosis within the lesions (resveratrol P < 0.01 and EGCG P < 0.05, versus control). Both compounds induced reduction in human EEC proliferation (P < 0.05 versus basal) and increased apoptosis (P < 0.05 versus basal) in primary cultures. LIMITATIONS: In vitro studies were only carried out in epithelial cells from human eutopic endometrium. WIDER IMPLICATIONS OF THE FINDINGS: The present findings are promising and will assist the development of novel natural treatments for endometriosis. STUDY FUNDING: This study was supported by ANPCYT (PICT 6384 BID 1201 OC-AR) and CONICET (PIP 5471), Argentina. None of the authors has any conflict of interest to declare.

La presencia de "células en anillo de sello" en el tejido ovárico es el marcador histológico clásico del tumor de Krukenberg. Un adenocarcinoma metastásico altamente agresivo y de baja sobrevida. En cambio, los fibromas ováricos son tumores del estroma generalmente benignos. Presentamos un caso muy infrecuente de fibroma celular con presencia de células en anillo de sello y revisamos los criterios para el diagnóstico diferencial con el tumor de Krukenberg.
The presence of signet-ring cells in ovarian tissue is classically described as histological marker of Krukenberg tumor. It is highly aggressive metastatic adenocarcinoma with low survival. In contrast, ovarian fibroid is a stromal tumor usually benign. We present a very rare case of cellular fibroma with presence of signet-ring cells and we review the criteria for differential diagnosis of Krukenberg tumor.

Osmium pyridine-bipyridine redox centers have been tethered to Au electrodes by chemical modification through Au-S and Au-C bonds respectively. 4-Mercapto benzoic acid and the reduction product of the aryl diazonium salt of 4-amino benzoic acid were reacted on Au surfaces, with further post-functionalization by chemical reaction of the osmium complex amino-pyridine derivative with the surface carboxylates. The resulting modified Au surfaces were characterized by polarization modulated infrared reflection absorption spectroscopy (PM-IRRAS), scanning tunneling microscopy (STM), X-ray photoelectron spectroscopy (XPS), resonant raman spectroscopy and cyclic voltammetry.

Los síntomas compatibles con vaginitis y vaginosis, son la causa más frecuente de consulta al ginecólogo. La descarga vaginal abundante y el prurito, constituyen la primera sospecha de estas patologías. Sin embargo, debemos tener presente que el aumento significativo de lactobacilos, conocido como lactobacilosis, puede expresarse también con los mismos síntomas y signos de una vulvovaginitis micótica. Si esta condición se mantiene en el tiempo, puede provocar un grado de acidez anormal en la vagina, y puede llevar a una lisis de las células epiteliales que se conoce como vaginosis citolítica. Este diagnóstico, aunque es poco frecuente, debemos sospecharlo especialmente, en aquellas mujeres que relatan tener múltiples consultas por candidiasis vaginal, con escasa o nula respuesta frente a la terapia antimicótica.
The symptoms consistent with vaginitis and vaginosis are the most common cause of the visit to the gynecologist. Heavy vaginal discharge and pruritus are the first suspicion of this pathology. However, the significant increase in lactobacilli, known as lactobacilosis can be expressed also with the same symptoms and signs of a fungal vulvovaginitis. If this condition is maintained overtime, can cause abnormal acidity in the vagina, and may lead to epithelial cell lysis, which is known as cytolytic vaginosis. This diagnosis, although rare, should be suspected especially in women who reported having multiple consultations for vaginal candidiasis, with little or no response to antifungal therapy.

Objetivo: Analizar la experiencia clínica de pacientes sometidas a histerectomía posparto (HPP). Método: Estudio retrospectivo de la HPP efectuadas en Clínica Las Condes entre enero de 2000 y diciembre de 2009. Resultados: Hubo 15.356 partos con 34 casos de HPP (incidencia de 2,2 histerectomías/1000 partos). La edad materna promedio fue de 36 años; 97 por ciento eran multíparas. La edad gestacional promedio al parto fue 36,1 semanas (rango: 27-40). Causas principales: acretismo placentario (61,8 por ciento), inercia uterina (20,6 por ciento) y rotura uterina (8,8 por ciento). En el 29,4 por ciento se realizó además la ligadura de arterias hipogástricas. Histerectomía total en el 85,3 por ciento. El 91,2 por ciento presentó complicaciones, la más frecuente correspondió a lesión vesical asociada a acretismo placentario (26,5 por ciento). En el postoperatorio inmediato hubo 29 casos de anemia, 10 casos de coagulación intravascular diseminada, 2 casos de hemoperitoneo (reoperadas) y 2 pacientes con choque hipovolémico. Hubo 1 caso de trombosis pelviana, 1 caso de trombosis de vena ovárica y 1 caso de fasceitis necrotizante. Tardíamente hubo 3 casos de depresión, 1 tromboembolismo pulmonar, 1 fístula vésico-vaginal y 1 proceso inflamatorio pelviano. No hubo muertes maternas. Transfusión de sangre y/o hemoderivados en 76,5 por ciento. Hubo 1 mortinato y 2 mortineonatos con un 8,5 por ciento (3/35) de muerte perinatal. Conclusiones: La HPP es una intervención de urgencia que se plantea frente a una hemorragia severa, secundaria a diversas patologías, durante o posterior al parto, asociada frecuentemente con cesárea anterior e inercia uterina.
Objetive: To analyze the clinical experience of peripartum hysterectomy (PH). Method: Retrospective review of women who required PH at Las Condes Clinic since January 2000 to December 2009. Results: In the study period 15,356 patients were delivered with 34 cases of PH (incidence: 2.2/1000 deliveries). The mean age was 36 years old, 97 percent were multiparous. The mean gestational age at delivery was 36.1 weeks (range: 27-40). Causes: placenta accreta (61.8 percent), uterine atony (20.6 percent) and uterine rupture (8.8 percent). In 29.4 percent a bilateral hypogastric ligation was added to the hysterectomy. Total hysterectomy was performed in 85.3 percent of cases. There was at least one complication in 91.2 percent women. The intraopertive bladder injury associated with placenta accreta was the most frequent complication (26.5 percent). Postoperative complications: 29 cases of anemia, 10 cases of disseminated intravascular coagulopathy, 2 hemoperitoneum that required surgical reexploration, 2 cases of hypovolemic shock, 1 case of pelvic thrombosis, 1 case of ovarian vein thrombosis and 1 case of necrotizing fasceitis. Late complications included depression, pulmonary embolism, bladder-vagina fistula and pelvic inflammatory disease. 76.5 percent required transfusion. There were no cases of maternal death with 8.5 percent of perinatal death. Conclusions: PH it is performed in patients with severe bleeding during or after labor and delivery, frequently is associated with serious maternal morbidity. Previous cesarean section with abnormal placental implantation and uterine atony were the most frequent indications.

La vulvodinia es una patología compleja y de difícil tratamiento. Se define como un dolor crónico de la vulva, que puede ser generalizado o localizado. La primera vez que se escribe sobre esta fue en 1889, por Skene. Sin embargo, es sólo hasta 1976, que los miembros de la International Society for Study of Vulvovaginal Diseases, reconocieron el dolor vulvar como una entidad patológica. Se estima una prevalencia de un 15 por ciento, con unas 14 millones de mujeres que lo padecen en EEUU. Generalmente consultan múltiples veces y a diferentes médicos, antes de llegar a un diagnóstico. No existen pruebas específicas, por lo que la clínica y el examen físico son las principales herramientas. Se deben excluir todas aquellas patologías que explican este dolor crónico vulvar. Su etiología es multifactorial, involucrando cambios a nivel de nociceptores, alteraciones de la inervación y la presencia de factores inflamatorios. Sin embargo, no podemos dejar de lado los aspectos psicosexuales, que pueden modular o desencadenar el dolor vulvar, al encontrar un sustrato alterado a nivel de estos tejidos. Basándose en estos aspectos, hoy existen diferentes tratamientos, que son efectivos si los utilizamos asociados y en forma gradual, ya que se potencian entre ellos.
Vulvodynia is a complex pathology and difficult to treat. In 1889 Skene was the first who write about this. However, only until 1976 the members of the International Society for Study of Vulvovaginal Diseases, recognized the vulvar pain as a disease entity. Prevalence estimated at 15 percent with an estimated 14 million women who suffer in the USA. A high number of gynaecologists do not know this diagnosis. For this reason women consult multiple times and to different doctors to reach a diagnosis. There are no specific tests for diagnosis. Finding in the clinical and physical examination are the main tools for this diagnosis. The different pathologies that could explain the presence of a chronic vulvar pain must be excluded. Undoubtedly its aetiology is multifactorial, involving changes in the number of nociceptors and alterations in the innervations, and the presence of inflammatory factors that may be the starting point of this pathology, as it seeks to explain the neuropathic theory. However we can not ignore the psychosomatic theory in explaining the psychosexual disorders as a trigger vulvar pain, in these altered tissues. Based on these aspects there are now treatments that are more or less effective when are gradually associated for better results.

Antecedentes: Durante la última década se han desarrollado numerosas técnicas para tratar quirúrgicamente la incontinencia de orina de esfuerzo (IOE), entre ellas las minicintas o mallas de tercera generación. Objetivos: Determinar la eficacia y seguridad del tratamiento de la IOE, mediante cinta MiniArc. Método: Estudio prospectivo, a corto plazo, de 24 mujeres ingresadas a la Unidad de Uroginecología de Clínica Las Condes, entre abril de 2008 y abril de 2009. Criterio de inclusión: IOE pura, al menos por un año, de carácter permanente y objetivada por urodinamia de monocanal. Todas debían tener hipermobilidad uretral e incontinencia de esfuerzo tipo II o II + III. En caso de prolapso genital, no debía constituir la indicación primaria de cirugía. Criterio de exclusión: Antecedente de cirugía por IOE y/o prolapso genital. Resultados: Tiempo operatorio con media de 8 minutos. Seguimiento preliminar con media de 6 meses. No hubo complicaciones en el intraoperatorio. Hubo un caso de obstrucción uretral en el postoperatorio inmediato. Al tercer 3 meses se registró un caso de urgencia de novo leve, con solución espontánea al mes de seguimiento. A los 30 días se registró cura en 23 (95,8 por ciento), mejoría en 1 (4,2 por ciento) y no hubo casos de falla. Conclusiones: El sistema MiniArc, en pacientes seleccionadas, es una técnica segura y eficaz en el tratamiento de la IOE. La incorporación de nuevos pacientes y el seguimiento a largo plazo, permitirá determinar la persistencia de estos buenos resultados.
Background: During the last decade we observed the development of numerous surgical techniques to treat stress urinary incontinence (SUI). One of these techniques is the MiniArc. Objective: To determine the efficacy and safety of the surgical treatment of SUI by MiniArc. Method: Prospective study of short follow-up, of 24 women admitted in the Urogynecology of Clínica Las Condes, between April 2008 and April 2009. Inclusion criteria: SUI at least for one year and permanent, objectified through a mono channel urodynamic. All women should have urethral hyper mobility and urinary incontinence type II or II + III. In cases with genital prolapse, it should not be the primary indication for surgery. Exclusion criteria: Antecedent of surgery for SUI and/or for genital prolapse. Results: The surgical time media of 8 minutes. The preliminary follow-up was between 1 and 13 months, media 6 months. There were no complications during the MiniArc application. In the immediate postoperative period there was a case of urethral obstruction. During the third month, there was a case of mild novo urge incontinence, which was resolved spontaneously after one month. At 30 days after surgery in 23 (95.8 percent) cure was registered, improvement in 1 (4.2 percent) and cases of failure not were observed. Conclusions: In selected patients, MiniArc is safe and effective in the treatment of SUI. The incorporation of new patients to these protocols and long term follow-up will determine the persistence of these good results.

Antecedentes: Los tumores adenomatoides (TA) son poco frecuentes. Se encuentran principalmente en el aparato reproductor femenino y especialmente en el útero. No existen reportes a nivel nacional sobre estos. Objetivos: Describir las características histológicas e inmunohistoquímicas de los TA uterinos. Método: Estudio descriptivo de 32 muestras ingresadas al Servicio de Anatomía Patológica de Clínica Las Condes. Las muestras estudiadas fueron recopiladas entre noviembre de 1999 y noviembre de 2008. Resultados: El diagnóstico de TA fue realizado en 21 histerectomías y 11 miomectomías. En 14 casos se diagnosticaron como lesiones nodulares únicas (43,8 por ciento) y en 18 junto a leiomiomas (56,2 por ciento). El tamaño promedio de las lesiones únicas fue 2,6 cm, significativamente mayor que aquellas asociadas a leiomiomas. El patrón histológico predominante más frecuente correspondió al tipo angiomatoide (81,3 por ciento), seguido por los patrones adenoide (9,4 por ciento), sólido (6,3 por ciento) y mixto (3 por ciento), no se encontraron TA quísticos. El estudio inmunohistoquími-co fue positivo en el 100 por ciento de los casos para citoqueratina AE1/AE3, calrretinina, vimentina y D2-40. Fue negativo para CD31 y CEA. Sólo un 6,3 por ciento (2 casos) fue positivo para citoqueratina 5/6. Conclusiones: Los TA corresponden a tumores benignos de origen mesotelial. Generalmente su diagnóstico es un hallazgo. Al presentarse en el útero, se confunden generalmente con leiomiomas o se presentan en conjunto con estos. En base a lo anterior el tratamiento de estas lesiones debe ser conservador, bastando con la resección del tumor.
Background: The adenomatoid tumors (AT) are rare. They are found mainly in the female reproductive system and especially in the uterus. There is not national reporting on these. Objective: To describe the his-tological and immunohistochemical features of uterine AT. Method: Descriptive study of 32 patients admitted to the Pathology Department of Clinica Las Condes. The cases studied were collected between November 1999 and November 2008. Results: The diagnosis of AT was performed in 21 hysterectomies and 11 myomectomies. In 14 patients were diagnosed as nodular single lesions (43.8 percent) and in 18 cases associated with leiomyomas (56.2 percent), the average size of single lesions was 2.6 cm, significantly greaterthan those associated with leiomyomas. The predominant histologic type most often correspond to angiomatoid (81.3 percent), followed by adenoid patterns (9.4 percent), solid (6.3 percent) and mixed (3 percent), the cystic pattern was not observed. The immunohistochemical study of ST was positive in 100 percent for cytokeratin AE1/AE3, calrretinin, vimentin and D2-40. It was negative for CD31 and CEA. Only 6.3 percent (2 cases) were positive for cytokeratin 5/6. Conclusions: The AT is a benign tumor of mesothelial origin. Usually the diagnosis is a finding. In the uterus they are generally mistaken with leiomyomas or it is in associated with them. Based on the foregoing the treatment of AT should be conservative, only with resection.

Antecedentes: El incremento en el hallazgo de quistes anexiales durante el embarazo sería el mayor uso de técnicas de reproducción asistida con hiperestimulación ovárica controlada. La complicación más frecuente sigue siendo la torsión anexial. Objetivo: Revisar el manejo de quistes anexiales complicados o persistentes, durante el embarazo, con resolución laparoscópica. Método: Revisión retrospectiva de 9 pacientes consecutivas, ingresadas al Departamento de Obstetricia y Ginecología Clínica Las Condes. Resultados: La edad gestacional de ingreso fue entre 5+5 y 27 semanas. Cinco casos fueron producto de fertilización asistida y cuatro espontáneos. Ocho (85,6 por ciento) embarazadas, ingresaron por dolor abdominal agudo. Otro caso ingresó a cirugía electiva por quiste ovárico persistente. Los quistes tenían entre 6 y 13 cm. En 5 se realizó sólo destorsión ovárica, en 1 ooforectomía y en 1 quistectomía. Se realizó punción, destorsión y fijación a ligamento útero ovárico, bilateral, en la otra paciente. Se registró un caso de fiebre en el postoperatorio. El alta hospitalaria fue a las 48 horas en 6 (67 por ciento), a las 72 en 2 y a las 96 en 1. El estudio biópsico diferido en 3 pacientes demostró: 1 quiste seroso paratubario, 1 quiste luteínico parcialmente hemorrágico y 1 infarto anexial. Todos los embarazos evolucionaron normalmente. Conclusión: Nuestra experiencia confirma que en el embarazo la laparoscopía es una buena opción al requerir una cirugía por quiste anexial complicado o persistente.
Background: Recent reviews show an increase in the finding of adnexal cysts during pregnancy. One reason could be the use of assisted reproductive techniques with controlled ovarian hyperstimulation. Objective: To review the experience in managing via laparoscopy complicated or persistent adnexal cysts during pregnancy. Method: Retrospective review of 9 consecutive patients, admitted at the Department of Obstetrics and Gynecology, Clínica Las Condes. Results: The gestational age was between 5+5 and 27 weeks. Five were the product of assisted fertilization and four spontaneous. Eight (85.6 percent) pregnant women were admitted by emergency room because of acute abdominal pain and another one went through elective surgery for persistent ovarian cyst. Preoperative diagnosis of the 8 patients admitted by emergency: adnexal cyst complicated with torsion in 6 (1 adnexal infarction) and 2 cases of acute abdomen. The cysts were between 6 and 13 cm. Type of surgery: in 5, only distortion; ovarian oophorectomy in 1 and cystectomy in one. Puncture, detorsión and bilateral fixation of uterine ovarian ligament, in another patient. One case required conversion to laparotomy with adnexectomy. Postoperative fever was observed in one patient. Discharge was at 48 hrs in 6 (67 percent) cases, at 72 hrs. in 2 and 96 hrs. in 1. Deferred biopsy performed in 3 patients showed: paratu-barian serous cyst, partially hemorrhagic luteal cyst, adnexal infarction. All pregnancies went on normally. Premature births are not reported. Conclusion: Our experience suggests that laparoscopic approach is a valid option for complicated or persistent adnexal cysts in pregnant women.

El síndrome de Fitz-Hugh-Curtis es una perihepatitis producida por una peritonitis secundaria al ascenso de bacterias, como resultado de una enfermedad inflamatoria pélvica. En la etapa crónica se pueden observar adherencias entre la pared abdominal y la superficie hepática, caracterizadas por la semejanza a "cuerdas de violín". Esta imagen es considerada criterio diagnóstico. Se presenta un caso de hallazgo de síndrome de Fitz-Hugh-Curtis, pesquisado durante la inspección rutinaria de la cavidad abdominopélvica, al finalizar una histerectomía laparoscópica.
The Fitz-Hugh-Curtis Syndrome is a perihepatitis secondary to peritonitis caused by ascending bacteria from a pelvic inflammatory disease. During the chronic phase may be observe adherences between the abdominal wall and the liver surface characterized by a "violin string" similarity. This image is considered criterion for the diagnosis. A case of incidental Fitz-Hugh-Curtis syndrome observed during a routinely abdo-minopelvic cavity inspection at the end of a laparoscopic hysterectomy is presented.

ANTECEDENTES: La neuralgia del nervio pudendo pocas veces es sospechada y menos diagnosticada. Por esta razón, las pacientes que la padecen, consultan múltiples veces antes de llegar a un diagnóstico definitivo. OBJETIVO: Revisar la seguridad y eficacia de la infiltración de nervio pudendo, en el tratamiento del dolor en pacientes con neuralgia del nervio pudendo. MÉTODO: Seguimiento prospectivo de cinco pacientes ingresadas bajo el diagnóstico de síndrome de atrapamiento del nervio pudendo. La edad media de las pacientes fue 45 años. Debían tener 2 criterios mayores o 1 criterio mayor asociado a 2 criterios menores. Dolor con al menos 6 meses de evolución. Sin tratamientos previos. A todas se les realizó encuesta de síntomas y signos de atrapamiento del nervio pudendo. Todas fueron infiltradas con corticoides y anestésico, guiada por tomografía axial computada. Se comparó el dolor antes y después de la infiltración con escala de 0 a 10. RESULTADOS: No hubo complicaciones durante el procedimiento. Todas disminuyeron el dolor después de la infiltración, y señalaron estar conformes con los resultados. CONCLUSIÓN: La infiltración del nervio pudendo guiada por tomografía axial computada, es una técnica segura y eficaz, en el control o disminución del dolor pelviano, ocasionado por neuralgia del nervio pudendo. Sólo el seguimiento permitirá evidenciar la mantención de los buenos resultados, o la necesidad de repetir la infiltración o de realizar cirugía de descompresión.
BACKGROUND: The pudendal neuralgia infrequently is suspected and diagnosed. Therefore the patients who suffer it consult manifold times before arriving at a definitive diagnosis. OBJECTIVE: To review the security and effectiveness of the pudendal nerve infiltration in the pudendal neuralgia treatment. METHOD: Prospective study of five patients under entrapment pudendal nerve syndrome diagnosis. The media age was 45 years old. All patients must have 2 greater criteria or 1 greater criteria associate to 2 smaller criteria. The pain must have an evolution of at least 6 months. They must not have antecedent of infiltration or surgery like treatment of this syndrome. A questionnaire of entrapment pudendal nerve syndrome was applied. The infiltration was with corticoids and anesthetic guided by CT scan. The patients classified their pain with a subjective scale; in which 0 is the pain absence and 10 is the maximum pain. The pain was compared before and after infiltration. RESULTS: Complication did not appear during the infiltration procedure. In one patient an asymmetry in the spine corresponding to the side of pain was observed. All patients diminished the pain after the infiltration. All indicated to be in agreement with the results. CONCLUSION: The pudendal nerve infiltration guided by CT scan is safe and effective technique in the treatment or diminish of the pudendal neuralgia. Only the follow-up will allow demonstrating the good results, or the necessity to repeat the infiltration, or the necessity of decompression surgery.

Entendemos por endoscopia a aquellos procedimientos que permiten diagnosticar y tratar patología por medio de instrumentos con los que se observa el interior del cuerpo humano. Los primeros tratamientos por medio de endoscopia fueron realizados por Hipócrates. Luego a través de la historia son múltiples los precursores, pioneros y tantos otros que entregaron invenciones que permitieron llegar hasta el laparoscopio moderno. Convirtiéndose en una herramienta indispensable en la actual cirugía ginecológica mínimamente invasiva. Las nuevas tecnologías han permitido desarrollar la robótica, de la cual no han permanecido ajenos los procedimientos laparoscópicos. Así es como nace el robot Da Vinci, que más que una tecnología del futuro, ya constituye una realidad del presente en la cirugía laparoscópica ginecológica.
We understand by endoscope to those procedures that allow diagnosing and treated pathologies by means of instruments with which we observed in the interior of the human body. The first treatments by means of endoscope were made by Hippocrates. Soon through history the precursors, pioneers and so many others are multiple that gave inventions that allowed arriving until modern laparoscopy; becoming an indispensable tool in the present minimally invasive gynecological surgery. The new technologies have allowed developing the robotics technologies of which the laparoscopy procedures have not remained out. Thus the Da Vinci robot has born, who more than a technology of the future already constitutes a reality of the present in the gynecological laparoscopic surgery.
