ABSTRACT
Resumen Objetivo: Reportar el caso de una paciente con intususcepción apendicular (IA), condición infrecuente, secundario a foco de endometriosis, patología que en los últimos años ha presentado un aumento en su incidencia. Material y Método: Historia clínica, imágenes preoperatorias e intraoperatorias obtenidas de la ficha clínica. Resultados: Mujer de 35 años con dolor abdominal crónico de 4 meses de evolución. Se realiza estudio colonoscópico evidenciando lesión de 15 x 8 mm en ostium apendicular intususceptada al lumen cecal, y enteroclisis por tomografía axial computarizada (TC) que confirma IA. Se realiza una resección ileocecal laparoscópica demostrando la invaginación del apéndice con biopsia que muestra un foco de endometrioma. Discusión: La IA es una condición infrecuente con una incidencia cercana al 0,01% en la población general. Las patologías benignas son la principal causa (77%), siendo la endometriosis la causa más frecuente. Conclusión: La IA por endometriosis es anecdótica, con sintomatología poco específica. Los estudios disponibles pueden orientar adecuadamente la presencia de IA, sin embargo, en algunas ocasiones puede confundirse con patologías neoplásicas, donde cobra importancia la cirugía para dilucidar la etiología.
Objective: To report the case of a patient with appendicular intussusception (AI), an infrequent condition secondary to a focus of endometriosis, a pathology that has increased incidence in recent years. Material and Method: Clinical case, history and images obtained from the clinical file and intraoperative records with the consent of the patient. Results: A 35-year-old woman with abdominal pain. Colonoscopy study showing a 15 × 8 mm lesion in the appendicular ostium intussuscepted to the cecal lumen, and a computerized tomography (CT) enteroclysis confirming AI. A laparoscopic ileocecal resection is performed, demonstrating invagination of the appendix secondary to an endometrioma focus. Discussion: AI is a rare condition, with an incidence close to 0.01% in the general population. Benign pathologies are the main cause (77%), endometriosis being the most frequent cause. Conclusion: AI due to endometriosis is anecdotal, with unspecific symptoms. The available studies can adequately guide the presence of AI, however, on some occasions it can be confused with neoplastic pathologies, where surgery is important to elucidate the etiology.

Partial discharges measurement is one of the most useful tools for condition monitoring of high-voltage (HV) equipment. These phenomena can be measured on-line in radiofrequency (RF) with sensors such as the Vivaldi antenna, used in this paper, which improves the signal-to-noise ratio by rejecting FM and low-frequency TV bands. Additionally, the power ratios (PR), a signal-processing technique based on the power distribution of the incoming signals in frequency bands, are used to characterize different sources of PD and electromagnetic noise (EMN). The calculation of the time length of the pulses is introduced to separate signals where the PR alone do not give a conclusive solution. Thus, if several EM sources could be previously calibrated, it is possible to detect pulses corresponding to PD activity.
ABSTRACT
Since the antibiotherapy for tuberculosis, psoas abscess is an infrequent disease. The psoas abscess can be divided in primary and secondary, being the primary the most infrequent. We present two other cases of primary psoas abscess treated in our hospital. We review also the symptoms, the diagnosis and the therapy of this disease.

A cross-sectional study was conducted to evaluate the transmission of swine influenza through occupational exposure and to assess some risk factors for zoonotic transmission in workers from commercial farms in Mexico. Seroprevalence to swine influenza subtypes was determined by hemagglutinin inhibition assay and was higher in exposed (E), in comparison with unexposed (UE) participants (P<0.05). Percentages of seropositivity between UE and E were 28.57% and 19.35% to A/NewCaledonia/20/99 (H1N1), 68.25% and 33.87% to A/Panama/2001/99-like (H3N2), 1.58% and 12.9% to A/Sw/England/163266/87 (H3N2), respectively. No antibodies were detected against A/Sw/Wisconsin/238/97 (H1N1) in the UE subjects, and only 3.22% were positive in the E group (P<0.05). A significant association between elevated antibody titres to swine influenza virus (SIV) H3N2 and the exposition to swine [OR 3.05, 95% (CI) 1.65-5.64] and to geographic location [OR 8.15, 95% (CI) 1.41-47.05] was found. Vaccination appeared as a protective factor [OR 0.05, 95% (CI) 0.01-0.52]. Farms with high number of breeding herd were associated with increased anti-SIV antibodies in the E group [OR 3.98, 95% (CI) 1.00-15.86]. These findings are relevant and support the evidence of zoonoses in swine farms and point out the need to implement preventive measures to diminish the occurrence of the disease and the potential emergence of pathogenic reassortant strains.

A two-year survey was carried out on the occurrence of avian influenza in migrating birds in two estuaries of the Mexican state of Sonora, which is located within the Pacific flyway. Cloacal and oropharyngeal swabs were collected from 1262 birds, including 20 aquatic bird species from the Moroncarit and Tobari estuaries in Sonora, Mexico. Samples were tested for type A influenza (M), H5 Eurasian and North American subtypes (H5EA and H5NA respectively) and the H7 North American subtype (H7NA). Gene detection was determined by one-step real-time reverse transcription polymerase chain reaction (RRT-PCR). The results revealed that neither the highly pathogenic avian influenza virus H5 of Eurasian lineage nor H7NA were detected. The overall prevalence of avian influenza type A (M-positive) in the sampled birds was 3.6% with the vast majority in dabbling ducks (Anas species). Samples from two birds, one from a Redhead (Aythya americana) and another from a Northern Shoveler (Anas clypeata), were positive for the low-pathogenic H5 avian influenza virus of North American lineage. These findings represented documented evidence of the occurrence of avian influenza in wintering birds in the Mexican wetlands. This type of study contributes to the understanding of how viruses spread to new regions of North America and highlights the importance of surveillance for the early detection and control of potentially pathogenic strains, which could affect animal and human health.

El posicionamiento anatómico de los túneles en cirugía de ligamento cruzado anterior, ha sido sugerido como una estrategia para reducir la inestabilidad rotacional y por tanto la artrosis futura. Las técnicas más comunes utilizadas para posicionar el túnel femoral son: la técnica transtibial y la técnica de portal anteromedial. Ha sido reportado que un posicionamiento anatómico del túnel femoral es imposible mediante la técnica transtibial, incluso con modificaciones. Por otra parte, la técnica de portal anteromedial si bien logra un posicionamiento más anatómico del túnel femoral, puede resultar en un túnel más corto, además de la posibilidad de causar daño al cartílago articular del cóndilo femoral medial durante el proceso de realización de este; y por último, existe el riesgo de dañar las estructuras neurovasculares al pasar las guías y brocas de medial a lateral. En un esfuerzo por ir mejorando las técnicas quirúrgicas disponibles, se ha desarrollado la técnica de túnel femoral retrogrado o retroconstrucción, la cual lograría posicionar un túnel femoral anatómico evitando las complicaciones de la técnica de portal anteromedial. En este artículo, presentaremos la técnica de Retroconstrucción de LCA con autoinjerto semitendinoso-gracillis, utilizando el instrumental FlipCutterTM (Arthrex Inc, Naples) con método de fijación femoral suspensorio Tight RopeTM (Arthrex Inc, Naples) y fijación tibial con tornillo interferencial BiocompositeTM (Arthrex Inc, Naples).
The anatomical positioning of tunnels in Anterior Cruciate Ligament (ACL) surgery has been suggested as a strategy to reduce rotational instability and osteoarthritis. Usual techniques used to make the femoral tunnel are the transtibial technique and the anteromedial portal technique. It has been reported that it is impossible to make an anatomical femoral tunnel using the transtibial technique, even with variations. Furthemore, the anteromedial portal technique can locate a more anatomical tunnel but has complications like short tunnel, damage to the medial femoral condyle and risks for the lateral neurovascular bundle. In an effort to improve our capacity of positioning an anatomical femoral tunnel with less complications, the retroconstruction technique has been developed. In this article we present the ACL retroconstruction technique using autologous semitendinous-gracillis graft with FlipCutterTM (Arthrex Inc, Naples).
