Beyond a "woman's problem" : the role of relationship processes in female genital pain

Female genital pain is a prevalent condition that can disrupt the psychosexual and relational well-being of affected women and their romantic partners. Despite the intimate context in which the pain can be elicited (i.e., during sexual intercourse), interpersonal correlates of genital pain and sexuality have not been widely studied in comparison to other psychosocial factors. This review describes several prevailing theoretical models explaining the role of the partner in female genital pain: the operant learning model, cognitive-behavioral and communal coping models, and intimacy models. The review includes a discussion of empirical research on the interpersonal and partner correlates of female genital pain and the impact of genital pain on partners’ psychosexual adjustment. Together, this research highlights a potential reciprocal interaction between both partners’ experiences of female genital pain. The direction of future theoretical, methodological, and clinical research is discussed with regard to the potential to enhance understanding of the highly interpersonal context of female genital pain

Diferencias individuales y desarrollo de habilidades de liderazgo : el rol del locus de control

El presente proyecto se ha elaborado con la finalidad de encontrar la relación existente entre el liderazgo y el locus de control, por medio de una revisión documental que permita dar una visión más amplia de estos dos fenómenos. De acuerdo con investigaciones realizadas, existen características individuales que afectan el desarrollo de liderazgo, lo cual a su vez tiene un impacto sobre el comportamiento de los individuos dentro de una sociedad. Uno de estos factores es el locus de control, el cual sesta determinado por características del individuo, y por el ambiente en el cual se desenvuelven las personas. Existen diferentes evidencias que soportan ésta relación entre locus de control y liderazgo. En éste estudio documental se describirán estos hallazgos, identificando las características del individuo y del contexto que influyen sobre ellos. Asimismo se pondrá en contexto a través del trabajo las características principales de los líderes y como se presentan las interacciones entre los lideres y seguidores, teniendo en cuenta que no todas las veces los seguidores desarrollan este papel al seguir a su líder, sino que por otro lado y estos pueden tomar parte fundamental en la interacción, influyendo de manera directa sobre el líder. Se recuerda que a los lideres los hacen sus seguidores y que sin estos no podrían desarrollar el papel de líder.

Análisis de la ayuda oficial al desarrollo. estudio de caso: programa conjunto de UNICEF y UNFPA sobre la mutilación genital femenina en Kenia (2008-2012)

El interés de este estudio de caso es analizar el Programa Conjunto de UNFPA y UNICEF sobre MGF/E en Kenia bajo la luz de los postulados poscolonialistas. Partiendo de la idea de que la MGF es una manifestación de las desigualdades de género, se argumenta que el PC reproduce la imagen de la mujer keniana como una víctima del poder masculino. A partir de esta imagen se deslegitima el orden cultural de los grupos que siguen esta tradición, afectando las lógicas de unidad y cohesión de la sociedad. El análisis de este tipo de dinámicas permite comprender mejor los procesos de intervención de las organizaciones internacionales sobre las estructuras sociales de actores frágiles del sistema internacional.

Anatomia macroscòpica i microscòpica de l'aparell genital femení d'Ophidion barbatum (L.) (Pisces, Ophididae)

S'ha realitzat un estudi de l'anatomia macroscòpica i microscòpica de I'ovari d'Ophidion barbatum (L.) (Pisces, Ophidiidae), utilitzant material recollit per pescadors del port de Blanes (mar català) durant el mes d'octubre de 1985. L'absència d'òrgan copulador en els mascles d'aquesta espècie i la posició de l'orifici nasal anterior, a una certa alçada respecte al llavi superior, ens permet identificar-la com una espècie ovípara, del subordre Ophidioidei, dins de l'ordre Ophidiiformes. L'ovari és únic i continuat caudalment per l'oviducte. Els nombrosos cordons intraovarics que tapien la cavitat augmenten considerablement la superfície germinal. El desenvolupament de l'ovari es correspon amb el tipus asincrònic (Marza, 1938) i la fresa repetida al llarg d'una estació reproductiva més o menys llarga és una estrategia que augmenta la fecunditat, normalment limitada pel volum corporal de la femella. Dins de l'ordre Ophidiiformes, el tipus d'ovari únic sense restes de paret mitjana sembla ser la norma entre les espècies de reproducció ovípara. Aquest fet esta en contradicció amb la teoria de Mendoza (1943) que, fora d'algunes excepcions, l'ovari únic es troba principalment en els teleostis vivípars

Effect of viral load on the outcome of herpes zoster

Varicella-zoster virus (VZV) is a member of the Herpesviridae family, primary infection with which causes varicella, more commonly known as chicken pox. Characteristic of members of the alphaherpesvirus subfamily, VZV is neurotropic and establishes latency in sensory neurons. Reactivation of VZV causes herpes zoster, also known as shingles. The most frequent complication following zoster is chronic and often debilitating pain called postherpetic neuralgia (PHN), which can last for months after the disappearance of a rash. During episodes of acute zoster, VZV viremia occurs in some, but not all, patients; however, the effect of the viral load on the disease outcome is not known. Here we describe the development of a highly specific, sensitive, and reproducible real-time PCR assay to investigate the factors that may contribute to the presence and levels of baseline viremia in patients with zoster and to determine the relationship between viremia and the development and persistence of PHN. VZV DNA was detected in the peripheral blood mononuclear cells (PBMCs) of 78% of patients with acute zoster and in 9% of healthy asymptomatic blood donors. The presence of VZV in the PBMCs of patients with acute zoster was independently associated with age and being on antivirals but not with gender, immune status, extent of rash, the age of the rash at the time of blood sampling, having a history of prodromal pain, or the extent of acute pain. Prodromal pain was significantly associated with higher baseline viral loads. Viral load levels were not associated with the development or persistence of PHN at 6, 12, or 26 weeks.

Persistence of varicella-zoster virus viraemia in patients with herpes zoster.

BACKGROUND: Herpes zoster is caused by the reactivation of varicella-zoster virus from sensory neurons. The commonest complication following zoster is chronic pain termed post herpetic neuralgia. OBJECTIVES: To investigate the dynamics of VZV viraemia and viral load following the resolution of zoster and its relationship to PHN development. STUDY DESIGN: Blood samples were collected at baseline, 1 month, 3 months and 6 month from a prospective study of 63 patients with active zoster. Quantification of VZV DNA in whole blood was performed using a real-time PCR assay. RESULTS: During acute zoster, all patients had detectable VZV DNA in their blood. VZV DNA remained detectable in the blood of 91% of patients at 6 months although levels declined significantly (p<0.0001). A history of prodromal symptoms (p=0.005) and severity of pain at baseline (p=0.038) as well as taking antivirals (p=0.046) and being immunocompromised (p=0.043) were associated, with longer time to recovery from PHN. Viral DNA loads were consistently higher in patients with risk factors for PHN and higher viral DNA loads over time were associated with longer time to recovery (p=0.058 overall and 0.038 in immunocompetent). CONCLUSIONS: Based on these observations we hypothesise that VZV replication persists following acute shingles and that higher viral DNA loads contribute to the risk factors for PHN.

Occurrence of herpes simplex virus 1 and three periodontal bacteria in patients with chronic periodontitis and necrotic pulp

Viral and bacterial associations appear to be implicated in the development of periodontal infections. Little information is available describing the periodontopathic agents in root canals with necrotic pulp. In this study, the occurrence and the combinations among herpes simplex virus type 1 (HSV-1) and Dialister pneumosintes, Tannerella forsythia.. and Treponema denticola in patients with chronic periodontitis and necrotic pulp were evaluated. Clinical samples from healthy subjects and patients with periodontal or pulp infections were analyzed using a nested polymerase chain reaction PCR to detect HSV and PCR to detect the 3 periodontal bacteria. The presence of Tannerella forsythia and Treponema denticola was observed in healthy, periodontitis, and necrotic pulp patients. HSV was observed in periodontitis and necrotic pulp patients, and no healthy subject harbored D. pneumosintes or HSV. The occurrence of Tannerella forsythia was not statistically significant in patients with necrotic pulp (P = 0.704). Periodontal bacteria were observed varying from 10.3% to 20.7% in periodontitis and necrotic pulp patients. The presence of Treponema denticola - HSV association was predominant in patients showing necrotic pulp (24.1%); however, HSV alone was observed in one patient with periodontitis and in another patient with necrotic pulp. The presence of double association among bacteria or bacteria - HSV could indicate a role in both periodontitis and necrotic pulp, and Tannerella forsythia - Treponenta denticola - HSV and Tannerella forsythia - D. pneumosintes - Treponema denticola - HSV associations might be important in periodontitis.
