Proceso de enfermería a embarazada con infección de vías urinarias y amenaza de aborto / A Nursing Process for a Pregnant Woman with Urinary Tract Infection and Threatened Miscarriage

Introducción: La infección de vías urinarias es recurrente en el embarazo y generadora de complicaciones. Objetivo: Presentar un plan de cuidados enfermero a una mujer con diagnóstico infección de vías urinarias y amenaza de aborto Métodos: Caso clínico de paciente admitida en unidad de Ginecología y Obstetricia del Hospital General de Teziutlán, Puebla, México, durante 2019. Siguiendo la lógica del proceso de enfermería, la valoración se fundamentó en los patrones funcionales de salud de Marjory Gordon. Fueron utilizadas las terminologías normalizadas de enfermería: Diagnósticos (NANDA.int). Resultados (NOC) e Intervenciones (NIC). Resultados: Se identificaron cuatro diagnósticos de enfermería: deterioro de la eliminación urinaria, gestión ineficaz de la propia salud, disposición para mejorar la nutrición y riesgo de alteración de la díada materno/fetal, este último diagnóstico principal. Además, un Resultado NOC (Conocimiento: Control de Infección), cuatro indicadores y la escala de nunca a siempre demostrado; cuatro Intervenciones NIC, con 19 actividades. La evaluación transitó desde 12 (puntuación inicial) a 19 (puntuación final), de 20 como puntuación diana. Conclusión: La integración de las taxonomías NANDA, NIC, NOC y los patrones funcionales de salud de Marjory Gordon permitió diseñar el plan de cuidado de la embarazada, fueron articulados diagnósticos, resultados e intervenciones de enfermería que favorecieron la relación enfermera-paciente-contexto sociocultural, para llevar el cuidado hasta una concepción sistémica que permita el seguimiento y control de la embarazada(AU)

Introduction: Urinary tract infection is recurrent in pregnancy and causes complications. Objective: To present a nursing care plan provided to a woman with a diagnosis of urinary tract infection and threatened miscarriage. Methods: Clinical case of a patient admitted to the gynecology and obstetrics unit of General Hospital of Teziutlán (Puebla, Mexico) during 2019. Following the logic of the nursing process, the assessment was based on Marjory Gordon's functional health patterns. The standard nursing terminologies were used: diagnostics (NANDA-I), outcomes (NOC) and interventions (NIC). Results: Four nursing diagnoses were identified: deterioration of urinary elimination, ineffective self-health management, willingness to improve nutrition, and risk for alterations in maternal-fetal dyad, the latter being the main diagnosis. In addition, a NOC outcome (knowledge: infection control), four indicators and the never-to-always scale upon demonstration, as well as four NIC interventions, with nineteen activities, were obtained. Evaluation ranged from twelve (initial score) to nineteen (final score), with twenty as target score. Conclusion: The integration of the NANDA, NIC and NOC taxonomies together with the Marjory Gordon's functional health patterns allowed the design of the pregnant woman's care plan, with an articulation between nursing diagnoses, outcomes and interventions, which favored the nurse-patient-sociocultural context relationship, up to considering care based on a systemic conception that allows monitoring and control of the pregnant woman(AU)

Conclusion:Urinary tract infection is a factor associated with the threatened preterm delivery in pregnant teens.

Progress on diagnosis and treatment of primary non- Hodgkin lymphoma in the female genital tract / 中国肿瘤临床

Primary lymphoma of female genital tract (PLFGT) is uncommon, and its etiology is unclear. It can present with pain, distention, vaginal bleeding, or discharge or be found as an incidental finding at a routine pelvic examination or surgery for other indications. PLFGT can be diagnosed with imaging, with pathomorphology being the key to diagnosing this disease. Further diagnosis and typing are needed with flow cytometry and immunohistochemistry. PLFGT should be differentiated from secondary genital lymphoma and other primary malignant tumors of the reproductive system. Preoperative diagnosis can be challenging due to its rarity. In addition, there is a lack of experience in treating PLFGT. Based on the pathological classification, staging, and non-Hodgkin lymphoma (NHL) guidelines, an individualized approach should be determined. R-CHOP has been found to significantly improve the survival of patients with NHL. However, the efficacy and safety of chemotherapy as the standard treatment for PLFGT still needs to be confirmed. Prognosis was evaluated according to the international prognostic index (IPI).

Clinicopathological analysis of primary non-Hodgkin's lymphoma of the female reproductive system / 中华放射肿瘤学杂志

Objective To retrospectively analyze the clinical pathological features and treatment outcomes of primary non-Hodgkin'slymphoma (NHL) of the female reproductive system.Methods A retrospective analysis was performed on the clinical data of 28 patients with primary NHL of the female reproductive system who were admitted to our hospital from 1990 to 2016.The lymphomas were classified and staged based on the WHO histological classification and the Ann Arbor staging system,respectively.Of the 28 patients,18 (64％) underwent surgery,27 (96％) received chemotherapy,and 8 (29％) received radiotherapy.The Kaplan-Meier method was used to calculate survival rates.Results The 5-year follow-up rate was 86％.The median age was 56.5 years (13-80 years).The ovary was involved in 11 patients (39％).The lymphoma was staged as IVE in 18 patients (64％).The most common pathological type was diffuse large B-cell lymphoma.The median survival time was 23.5 months.The 1-,3-,and 5-year overall survival rates were 89％,74％,and 59％,respectively.Conclusions Primary NLH of the female reproductive system is an extremely rare neoplastic disorder with no typical clinical symptoms and mostly diagnosed in advanced stage.The combined treatment with surgery,chemotherapy,and radiotherapy plays an important role in the treatment of the disorder.

Imaging features of oblique vaginal septum syndrome and its diagnostic value / 实用放射学杂志

Objective To investigate the imaging findings of oblique vaginal septum syndrome and its diagnostic value.Methods Clinical and radiographic data of 13 patients with oblique vaginal septum syndrome were analyzed retrospectively and relevant literatures were reviewed.All 13 patients underwent ultrasonography examination preoperatively,and 8 of them underwent MRI examination,and 3 patients underwent CT examination as well.The position of the oblique septum,the size of the cavity in the rear of oblique septum, the positional relationship between the cavity in the rear of oblique septum and the cervix,and the concomitant changes of the uterine appendages and urinary system were analyzed.Results The ultrasonography and MRI examinations all manifested as uterus didelphys,cervix duplex,double vagina and obstructed hemivagina,and oblique septum originated from the middle of cervix duplex and attached to one side of the vaginal wall,shielding the ipsilateral cervix;oblique vaginal septum was on the right side in 4 cases and on the left side in 9 cases;the average volume of the cavity in the rear of oblique septum in 6 cases of type Ⅰ was 255 mL,and the average volume in 6 cases of type Ⅱ was 74 mL,and the volume in 1 case of type Ⅲ was 56 mL;2 cases were combined with ipsilateral hematosalpinx and 1 case was combined with a chocolate cyst of ipsilateral ovary;12 cases were accompanied with ipsilateral renal agenesis and 1 case was accompanied with ipsilateral renal hypoplasia.CT examinations of 3 cases all presented as uterus didelphys,a cystic hypodensity lesion under unilateral cervix and ipsilateral renal agenesis.Conclusion Imaging findings of oblique vaginal septum syndrome are quite characteristic. Ultrasonography,CT and MRI examinations have certain value for accurate diagnosis of the disease.

Association of mycoplasma infection with genital system tumor: A system evaluation / 中国人兽共患病学报

We explore the association of the mycoplasma infection with genital system tumor.Some index word including prostate cancer,cervical cancer,ovarian cancer and mycoplasma were used in some electronic databases (including PubMed,Web of Science,Chinese biomedical database,wanfang database,CNKI) to search literatures.The R software was used for the meta-analysis.The Newcastle-Ottawa Scale (NOS) was used to evaluate the quality of the literature.Publication bias was evaluated by funnel figure,and the fail-safe number (Nfs) was calculated to estimate the reliability of the meta-analysis.Result showed that 20 articles were included,the numbers of cases and controls were 2 345 and 2 728 respectively.The pooled OR of Ureaplasma urealyticum(Uu),Mycoplasma hominis(Mh),other mycoplasma,mixture of mycoplasma and the whole mycoplasma was 2.19(95％CI:1.27-3.79),1.74(95％CI:1.28-2.35),1.97(95％CI:1.03-3.77),3.54 (95％CI:1.33-9.41),1.29(95％CI:1.53-2.60),respectively.The fail-safe number of Uu,Mh,other mycoplasma and mixture of mycoplasma was 254,42,31,157 respectively.There are some possibility about the association between the mycoplasma infection and the genital system cancer;maybe the infection would increase the tumorigenesis risk.It is necessary to research further about these associations in different mycoplasmas respectively.

Tailored therapy and long-term surveillance of malignant germ cell tumors in the female genital system: 10-year experience / 부인종양

OBJECTIVE: To explore the appropriate treatment of malignant germ cell tumor (MGCT) in the female genital system, and to analyze the factors influencing both therapeutic response and survival outcome. METHODS: A cohort of 230-Chinese women diagnosed with MGCT of the genital system was retrospectively reviewed and prospectively followed. The demographic and pathological features, extent of disease and surgery, treatment efficiency, recurrence and survival were analyzed. RESULTS: MGCTs from different genital origins shared a similar therapeutic strategy and response, except that all eight vaginal cases were infantile yolk sac tumors. The patients' cure rate following the initial treatment, 5-year overall survival and disease-free survival (DFS) were 85.02%, 95.00%, and 86.00%, respectively. Although more extensive excision could enhance the remission rate; it did not improve the patients' survival. Instead, the level of the medical institution, extent of surgery and disease were independent prognostic factors for relapse (p<0.05). Approximately 20% of patients had recurrent or refractory disease, more than half of whom were in remission following secondary cytoreductive surgery with salvage chemotherapy. CONCLUSION: Fertility-sparing surgery with or without standardized PEB/PVB (cisplatin, etoposide/vincristine, and bleomycin) chemotherapy is applicable for female MGCTs of different origins. Comprehensive staging is not required; nor is excessive debulking suggested. Appropriate cytoreduction by surgery and antineoplastic medicine at an experienced medical institution can bring about an excellent prognosis for these patients.

Morfologia do escroto, do testículo e das vias espermáticas de Metachirus nudicaudatus (Geoffroy, 1803), Didelphidae-Marsupialia / Morphology of scrotum and testicle, and spermatic pathways of Metachirus nudicaudatus (Geoffroy, 1803), Didelphidae-Marsupialia

Foram utilizadas as gônadas e vias espermáticas de cinco animais machos, adultos em fase reprodutiva, da espécie Metachirus nudicaudatus Geoffroy 1803, única espécie do gênero, para descrever a morfologia do escroto, do testículo e das vias espermáticas. O Metachirus possui escroto pré-peniano e que contém os testículos permanentemente. A pele escrotal é não pigmentada e com poucos pelos e glândulas. A lâmina parietal da túnica vaginal apresenta-se pouco pigmentada. Os testículos são ovais e ligados ao epidídimo através do pedículo testículo-epididimário. Eles são envolvidos, externamente, pela cápsula testicular e sustentados por um estroma de natureza conjuntiva. As células intersticiais são os elementos predominantes no abundante tecido intertubular. Os túbulos seminíferos são largos, enovelados e envolvidos por uma túnica própria fibroelástica, contendo células mióides. O epitélio seminífero é formado pelas células espermatogênicas e de Sertoli intercaladas. Os túbulos seminíferos convergem em direção à extremidade capitata do testículo, ficando revestidos por apenas células de sustentação, caracterizando uma região de transição entre túbulos seminíferos e túbulos retos, ocupada por uma estrutura tipo "válvula" que obstrui parcialmente o lume tubular. Os túbulos retos reúnem-se para formar um único dúctulo eferente, que percorre uma pequena extensão intratesticular, atravessa a albugínea e penetra no pedículo testículo-epididimário. A parte flexuosa do dúctulo eferente forma um lóbulo separado na parte medial do corpo do epidídimo. O epidídimo é envolvido pela cápsula epididimária e constituído pelo ducto epididimário, que se encontra bastante enovelado. O ducto epididimário é revestido por epitélio simples colunar pseudoestratificado apresentando células principais, basais, apicais e de "halo claro". As células principais são predominantes e apresentam características morfológicas e histoquímicas que diferem ao longo do ducto, possibilitando a caracterização de nove diferentes zonas epididimárias. É no lume da zona sete (início da cauda) que começa o pareamento de espermatozoides. Esse fenômeno coincide com alterações morfológicas bem evidentes e uma maior quantidade de mucossubstâncias neutras é secretada nessa zona.O ducto deferente apresenta-se dividido em três partes: justa-epididimária, funicular e abdominal, baseando nas variações histológicas e histoquímicas de seu epitélio e componentes envolventes. O ducto deferente não apresenta ampola e nem cruza o ureter antes de desembocar na uretra. O funículo espermático contém o ducto deferente, artéria e veias testiculares, vasos linfáticos, nervos e um desenvolvido músculo cremáster. Seus componentes apresentam modificações estruturais nas regiões proximal, média e distal, sendo notável a peculiar rede admirável.(AU)

Gonads and sperm pathways of five adult male Metachirus nudicaudatus in the reproductive phase were used to describe the morphology of scrotum, testicle, and spermatic tract. M. nudicaudatus has a scrotum pre-penis which contains the testicles permanently. The scrotal skin is not pigmented and has few hairs and glands. The parietal vaginal tunic is slightly pigmented. The testicles are oval and connected to the epididymis by testicular-epididymal pedicle; they are surrounded externally by the testicular capsule and supported by a stroma of connective nature. Interstitial cells are the predominant elements in abundant intertubular tissue. The seminiferous tubules are wide, meandering and surrounded by a fibro-elastic coat, containing myoid cells. The seminiferous epithelium is composed of spermatogenic cells and Sertoli cells interspersed. The seminiferous tubules converge toward the end of the testis capitata, getting coated only support cells, featuring a transition region between the seminiferous tubules and straight tubules, occupied by a type "valve" structure that partially blocks the tubular lumen. Straight tubules together to form a single efferent ductule, which runs a small intra-testicular extent, penetrates through the tunica and the pedicle testis-epididymis. The flexuosa part of the efferent ductule forms a separate lobe in the medial part of the body of the epididymis. The epididymis is enveloped by a capsule and epididymal comprising the epididymal duct, which is quite entangled. The epididymal duct is lined by pseudostratified columnar epithelium with simple principal, basal, apical and "clear halo" cells. The main cells are prevalent and have morphological and histochemical differing characteristics along the duct, enabling to characterize nine different epididymal areas. In the lumen of the seventh area (top of tail) that starts the pairing of sperm. This phenomenon coincides well with morphological change and a larger amount of neutral muco-substances is secreted in that area. Vas deferens has three parts: fair-epididymal, abdominal and funicular part, based on histological and histochemical changes of the epithelium and surrounding components. The vas deferens has no bulb and even crosses the ureter before flowing into the urethra.

Prune belly syndrome (sequenze): a case report.

The Prune Belly syndrome (PBS) also known as Eagle Barret syndrome is a rare disorder. It is an abdominal muscles deficiency syndrome characterized by a Triad syndrome i.e. deficiency of abdominal wall muscles, failure of testicular descent and dilation of the urinary tract. This syndrome has derived its name from the wrinkled prune appearance of the abdominal wall. Prune Belly syndrome is a rare anomaly seen in one in 35,000-50,000 live births. It occurs in all races. Prune Belly syndrome almost exclusively occurs in males (M:F, 20:1). The diagnosis can be made in utero by ultrasonography at 21 weeks of gestation or in the Neonate with characteristic clinical findings. The present case was a dead male fetus of 20 weeks of gestation sent to Anatomy department after Medical termination of pregnancy, due to congenital anomalies identified in routine ultrasound examination during antenatal checkup.

Caracterização histopatológica e imuno-histoquímica de neoplasmas mesenquimais da genitália em 43 cadelas / Histopathological and immunohistochemical characterization of mesenchymal neoplasms of the genitalia in 43 bitches

Os arquivos de biópsia do período de 2000 a 2010 do SPV-UFRGS foram revisados e levantados os casos de neoplasias mesenquimais de genitália (útero, cérvix, vagina e vulva) de cadelas. Realizou-se estudo retrospectivo de 43 casos, incluindo caracterização histológica, coloração tricrômico de Masson (TM) e imuno-histoquímica (IHQ). As principais raças acometidas foram Cocker, Poodle e Pastor Alemão, porém o maior número de casos foi observado em cães sem raça definida (SRD). A idade média dessas cadelas foi de 10,6 anos (variação de 3 a 10 anos). Quanto à localização dos tumores, 44,2% estavam na vagina, 27,9% no útero, 23,3% na vulva e 4,6% na cérvix. Histologicamente, 46,5% eram leiomioma, 41,9% fibroleiomioma, 7,0% fibroma e 4,6% leiomiossarcoma. Na coloração de TM, os fibromas apresentaram todas as células neoplásicas coradas em azul (colágeno), os leiomiomas e os leiomiossarcomas apresentaram menos de 50% de colágeno em meio às células neoplásicas musculares e os fibroleiomiomas mais de 50%. Na IHQ, os fibromas apresentaram marcação positiva para vimentina e negativa para desmina. Todos os leiomiomas eram positivos para vimentina (em mais de 50% células) e para desmina (75% dos casos em mais de 50% das células e 25% em menos de 50%). Em um dos casos de leiomiossarcoma houve imunomarcação para vimentina e ausente para desmina e, no outro, ocorreu o oposto. Os fibroleiomiomas apresentaram marcação para vimentina em 94,4% (em mais de 50% células) e para desmina em 77,8% (64,3% em menos de 50% das células e 35,7% em mais de 50%).

The biopsies archives from SPV-UFRGS (2000-2010) were retrieved, and cases of mesenchymal neoplasms of genitalia (uterus, cervix, vagina, and vulva) of 43 bitches were revised. Also Masson's trichrome staining (MT) and immunohistochemical characterization were evaluated. The main breeds affected were Cocker, Poodle and German Shepherd, but the greatest number of cases were observed in mixed breed dogs. The average age of the bitches was 10.6 years (3-10 years of age). The anatomical locations of the neoplasms were vagina (44.2%), uterus (27.9%), vulva (23.3%) and cervix (4.6%). Histologically, 46.5% were classified as leiomyoma, 41.9% as fibroleiomyoma, 7.0% as fibroma, and 4.6% as leiomyosarcoma. In MT staining, the fibroma had all neoplastic cells stained blue (collagen), the leiomyomas and leiomyosarcomas had less than 50% of collagen among the muscle neoplastic cells, and the fibroleiomyomas had more than 50% of collagen. Positive immunostaining for vimentin and absence for desmin was observed in fibroma. Leiomyomas were positive for vimentin in more than 50% of the cells, and for desmin (in 75% of the cases in more than 50% of the cells, and in 25% less than 50%). Regarding leiomyossarcomas, one case had immunostaining for vimentin and absence for desmin, and the opposite occurred in the other. Fibroleiomyomas were positive for vimentin in 94.4% (in more than 50% of the cells) and for desmin in 77.8% (64.3% in less than 50% of the cells, and 35.7% in more than 50% of the cells).

Morphological Diversity of the Ovaries of the Mexican Teleost Fishes / Diversidad Morfológica de los Ovarios de los Peces Teleósteos de México

The morphological diversity of the ovaries from a total of 90 species of teleosts in the Mexican fauna was analyzed. Ovaries were classified according to the following characters: their number, symmetry, fusion grade, trajectory, cross section, and topographical location. The fusion of both left and right ovaries was the character showing most diversity, mainly in the Cyprinodontiformes and its tendency to the viviparity. However, the most notably character was the extravisceral development of the ovaries in the Pleuronectiformes, implying the forward orientation of the gonoduct and the forward position of the female genital opening. The urogenital system of a typical perciform, Bairdiella chrysoura is proposed as a morphological pattern of the Teleostei.

Se reconoció una diversidad morfológica de los ovarios dentro de un conjunto de 90 especies de teleósteos de la fauna mexicana. Se clasificaron los ovarios de acuerdo con los siguientes caracteres: número de ovarios, su simetría, el grado de fusión entre sí, su trayectoria, el aspecto en sección transversal y su ubicación topográfica. Se reconoce el carácter de la fusión de ambos ovarios entre sí, como el que presentó la mayor diversidad de situaciones, sobresaliendo la tendencia a la total fusión dentro de los Cyprinodontiformes y su relación con la viviparidad. Sin embargo, el carácter más notable fue el desarrollo extravisceral de los ovarios en los Pleuronectiformes, que implica la orientación del gonoducto hacia delante y la posición adelantada de la abertura genital. Se propone como patrón morfológico del sistema urogenital de los Teleostei a un típico perciforme, Bairdiella chrysoura.

Patologias genitais associadas à leishmaniose visceral canina / Genital pathologies associated with canine visceral leishmaniasis

A leishmaniose visceral canina (LVC) é uma doença parasitária crônica causada por protozoários pertencentes ao gênero Leishmania. No Brasil, a transmissão se dá, principalmente, pela ação hematófaga de insetos vetores pertencentes à subfamília Phlebotominae, particularmente, a espécie Lutzomyia longipalpis. Todavia, a trasmissão vertical e venérea da LVC está presente. Os principais sinais clínicos observados nos animais acometidos pela LVC são linfoadenomegalia, dermatopatias, hepatoesplenomegalia, onicogrifose e oftalmopatias, contudo quadros atípicos podem ser observados, inclusive com o envolvimento do sistema genital. Dessa forma, o objetivo deste artigo é realizar revisão sobre as principais patologias genitais em cães machos e fêmeas com leishmaniose visceral (LV).

The canine visceral leishmaniasis (CanL) is a chronic parasitic disease caused by protozoa belonging to the genus Leishmania. In Brazil, the transmission occurs mainly by the action of blood-sucking insects belonging to the subfamily Phlebotominae, particularly the Lutzomyia longipalpis species. However, the venereal and vertical transmission of the CanL is present. The main clinical signs observed in animals affected by the CanL are lymphadenopathy, skin diseases, hepatosplenomegaly, onychogryphosis and ophthalmopathy, however atypical manifestations can be observed, including the involvement of the genital system. Thus, the aim of this paper is to review on the major pathologies in genital male and female dogs with visceral leishmaniasis (VL).

The correlation between the type of hypospadias and external genital system malformations / 中华泌尿外科杂志

Objective To investigate the correlation of the type of hypospadias and external genital system malformations. Methods From Jan 2000 to Oct 2009, the data of 632 patients diagnosed with hypospadias was analyzed retrospectively. The proportion of all types of hypospadias and the frequency of external genital system malformations were statistically analyzed. Results Among all cases, 12.6% exhibited mild hypospadias, 22. 8% moderate, 43. 2% severe and 21.4% had extremely severe hypospadias. One hundred and eighty-four cases with external genital system malformations were classified into penoscrotal transposition, cryptorchidism, hydrocele of tunica vaginalis,concealed penis and pseudovagina. The probability was about 24.8% (157 cases) of 632 patients with hypospadias. There was significant difference and a positive correlation among the type of hypospadias with total malformations, penoscrotal transposition, cryptorchidism. Conclusions In this patient cohort, moderate and severe hypospadias accounted for the majority of hypospadias. Penoscrotal transposition was the most frequent external genital system malformation in hypospadias, followed by cryptorchidism and hydrocele of tunics vaginalis. More severe hypospadias is accompanied with a higher probability of the external genital system malformations, penoscrotal transposition and cryptorchidism.

Hallazgos patológicos del tracto reproductivo en cerdas de descarte en Venezuela

En el avance hacia la obtención de la productividad del rebaño, es fundamental el adecuado conocimiento tanto de la anatomía como de la fisiología de la reproducción porcina. Dentro de la producción, uno de los parámetros que incide con mayor relevancia en la productividad es el número de lechones destetados por cerda por año, ya que de él depende el número final de cerdos que va a matadero. Este parámetro va a estar influenciado directamente por el desempeño reproductivo del rebaño de cría. Las fallas reproductivas son una de las principales causas de descarte, de ahí que el examen de los órganos reproductivos es una herramienta de gran valor diagnóstico en el manejo reproductivo porcino. La evaluación de estos órganos provee de una serie de datos sobre las posibles causas de falla reproductiva y a su vez, va a permitir tomar medidas correctivas a nivel de rebaño. En Venezuela, no existen reportes que describan los hallazgos patológicos observados en cerdas de descarte. De aquí que se plantea como objetivo general de esta investigación describir cuáles eran los hallazgos patológicos presentes en el tracto reproductivo de cerdas a través del análisis de muestras recolectadas en un matadero industrial del estado Aragua. Se evaluó un total de 125 tractos reproductivos encontrándose diferentes hallazgos macroscópicos en 23 animales (18,4%), desglosándose los mismos de la manera siguiente: 8,94% (11/123) de animales con ovarios inactivos o anestro (sin cuerpos lúteos ni folículos o con folículos con un diámetro < 5 mm), 13,01% (16/123) presentaron quistes en los ovarios, 5,6% (7/125) mostraron úteros con material purulento y de éstos en uno se encontró un feto retenido en proceso de descomposición y otro con ausencia de oviducto (cuerno ciego); en 17,6% (22/125) de los animales se evidenció procesos inflamatorios compatibles con cuadros de endometritis.

Pathological Findings of the Reproductive Tract from Culled Sows in Venezuela Abstract In order to advance towards the attainment of productivity in swine production, the adequate knowledge of the anatomy, as well as of the reproductive physiology of the sow is essential. In terms of production, one of the parameters that greatly influence productivity is the number of pigs weaned by sow per year, as this parameter determines the number of pigs delivered to the market. This parameter is directly influenced by the reproductive performance of the herd. Reproductive failure is one of the major causes of culling sows; therefore, a thorough examination of the reproductive tract is a valuable diagnostic tool in swine reproductive management. The evaluation of these organs provides us with a series of data on the possible causes of reproductive failure. At the same time, such an evaluation, will allow us to take corrective measures in the herd. In Venezuela, there is no available data describing the pathological findings observed in the reproductive tract of culled sows. The purpose of this investigation was to describe the pathological findings that affect the reprodcutive tract of culled sows. Samples were collected from a slaughterhouse, located in the State of Aragua, Venezuela. A total of 125 reproductive tracts was collected. Results of this investigation show that only 23 animals (18.4%)exhibited abnormal findings which were classified as follows: 8.94% (11/123) sows with inactive ovaries or anestro (neither corpora lutea nor follicles, or follicles with a diameter < 5 mm); 13.01% (16/123) had evidence of ovarian cysts, and 5.6% (7/125) showed uteri with purulent material: one had a retained fetus in decomposition process, and another lacked an oviduct (blind horn); 17.6% of the animals showed inflammatory processess compatible with endometritis.

Efeitos da melatonina no sistema genital feminino: breve revisão / Melatonin effects on the female genital system: a brief review

A melatonina é um hormônio produzido pela glândula pineal, cuja secreção está diretamente relacionada ao ciclo claro-escuro. É um poderoso antioxidante e tem papel fundamental na regulação do estado sono/vigília, do ritmo de vários processos fisiológicos, participando do controle do relógio biológico, inclusive nos seres humanos. Ressalta-se que há evidências da sua ação no sistema genital feminino, influenciando a função ovariana e a fertilidade. De fato, este hormônio interage com esteróides sexuais, como o estrogênio, modificando a sinalização celular e a resposta no tecido alvo. Estudos clínicos sugerem que o tratamento com a melatonina interviria com a evolução de neoplasia-dependente do estrogênio. O objetivo dessa revisão é analisar as principais ações da melatonina no sistema neuroendócrino, no ciclo sono-vigília, no sistema imunológico, no sistema cardiovascular, bem como no sistema reprodutor.

Melatonin is secreted by the pineal gland and this is linked to the day/night cycle. It is an antioxidant and plays a fundamental role in the regulation of the jet-lag stage, in several physiological reactions and in control of the biologic rhythm. Human melatonin has an important influence on the female genital system. In fact, melatonin may influence production and action of steroids, modifying cellular signalization on the target tissue. There are many evidences that the melatonin therapy may be interfering with neoplasia development, mainly of the estrogen-dependent tumor. This paper aims to analyze the actions of melatonin on the neuroendocrine, immunological and cardiovascular systems, as well as on the reproductive function.
