Intestinal Nonrotation, Imaging Findings in the Malrotation Spectrum: Case Report

Intestinal nonrotation is a rare embryonic developmental anomaly with a reported incidence of up to 0.5% in autopsies. Given the asymptomatic course, the diagnosis may be late, so it becomes an incidental finding. This study presents the most common imaging characteristics to familiarize readers with this pathology. We describe the case of a 73-year-old patient who consulted for pain in the right inguinal region associated with the sensation of a mass. There were no significant findings on physical examination. An abdominal tomography with contrast was requested as a study method, identifying a reversal of the superior mesenteric artery/superior mesenteric vein relationship with the cecum, appendix, and ileocecal valve in the left flank and mesogastrium. A displacement of thin intestinal loops towards the right hemiabdomen was also noted.

La no rotación intestinal es una anomalía del desarrollo embrionario poco frecuente con una incidencia reportada de hasta el 0,5 % en autopsias. El diagnóstico puede ser tardío dado el curso asintomático, por lo que se convierte en un hallazgo incidental. El objetivo de este estudio es dar a conocer las características por imagen más comunes para familiarizar a los lectores con esta patología. Se presenta el caso de un paciente de 73 años que consultó por dolor en la región inguinal derecha asociado a sensación de masa. En el examen físico no hubo hallazgos significativos. Se solicitó una tomografía abdominal con contraste como método de estudio y se identificó una inversión de la relación entre la arteria y vena mesentérica superior con la presencia de ciego, apéndice y válvula ileocecal en el flanco izquierdo y mesogastrio. Adicionalmente, se observó un desplazamiento de asas intestinales delgadas hacia el hemiabdomen derecho.

The Gender Violence - Implicit Association Test to measure attitudes toward intimate partner violence against women

Attitudes play a central role in intimate partner violence against women and are related to its origin, to the responses of women who suffer violence, and to the settings where it occurs. In fact, these attitudes are recognized as one of the risk factors linked to violent perpetration and to public, professional, and victim responses to this type of violence. However, even though available research generally shows a broad rejection of this violence, it remains a serious social and health problem that has reached epidemic proportions. This suggests that the information available about these attitudes (obtained through explicit and direct measures, i.e., self-reports) may be distorted or influenced by factors such as social desirability. In this context, the overall objective of our research project is to provide multi-method measures (explicit and implicit) of attitudes toward intimate partner violence against women, and the main goal of this paper is to propose an instrument for the implicit measurement of these attitudes. In this regard, the Implicit Association Test (IAT) is the most common procedure used, providing a superior predictive validity compared to explicit measures for socially sensitive topics. We will present an exploratory study that describes its adaptation for our purposes, and the development of the Gender Violence - Implicit Association Test (GV-IAT) to use among Spanish-speaking populations, and discuss the strengths and limitations of this proposal.

Manifestaciones cutáneas de lupus eritematoso sistémico temprano y correlación con la actividad sistémica / Cutaneous manifestations of early systemic lupus erythematosus and correlation with systemic activity

Las manifestaciones cutáneas del lupus eritematoso sistémico (LES) son heterogéneas (específicas e inespecíficas). Poco se sabe acerca de la relación entre estas manifestaciones y la actividad clínica e inmunológica de la enfermedad en sus etapas iniciales. Se llevó a cabo un estudio de corte transversal en 34 pacientes con LES temprano. Se encontró una asociación significativa entre alopecia e hipocomplementemia C3 (p = 0,021), hipocomplementemia C4 (p < 0,001) y anti-Sm (p = 0,011); entre eritema malar y anti-Ro (p = 0,037) y anti-La (p = 0,037); entre fotosensibilidad y anti-RNP (p = 0,037). Se observó una tendencia a la asociación entre úlceras orales e hipocomplementemia C4 (p = 0,064). No hubo asociación entre las manifestaciones cutáneas y la presencia de anti-ADN de doble cadena (anti-ds ADN), anticuerpos anticardiolipinas, anticoagulante lúpico, VDRL falso positivo, leucopenia, trombocitopenia, hipergammaglobulinemia, elevación de la velocidad de sedimentación globular o SLEDAI. Se resalta la importancia de la relación entre las manifestaciones cutáneas inespecíficas de LES (alopecia y fotosensibilidad) y la actividad sistémica en pacientes con enfermedad temprana y la clara asociación de estas con hipocomplementemia, un marcador importante de actividad inmunológica.

Cutaneous manifestations of systemic lupus erythematosus (SLE) are heterogeneous (both specific and non-specific). Little is known about the relationship between these manifestations and the clinical and immunological activity of the disease in early stages. We carried out a cross-sectional study in 34 patients with early SLE. We found a significant association between alopecia and hypocomplementemia C3 (p = 0.021), hypocomplementemia C4 (p < 0.001) and anti-Sm (p = 0.011); between malar erythema and anti-Ro (p = 0.037) and anti-La (p = 0.037); between photosensitivity and anti-RNP (p = 0.037). We observed a trend to association between oral ulcers and hypocomplementemia C4 (p = 0.064). No association was found between cutaneous manifestations and the presence of anti-ds DNA, anticardiolipin antibodies, lupus anticoagulant, false-positive VDRL, leucopenia, thrombocytopenia, hypergammaglobulinemia, elevated erythrosedimentation rate or SLEDAI. We highlight the relevance of the relationship between non-specific cutaneous manifestations of early SLE (alopecia and photosensitivity) and the systemic activity of the disease and hypocomplementemia, an important marker of immunological activity.
