Transmesocolic hernia with sigmoid colon strangulation without surgical history...

The incidence of internal hernias is rare (0.2-0.9%). The prevalence of intestinal obstruction for an internal hernia is low (0.5-5%), however if strangulation is present the overall mortality is higher than 50%. There are multiple places where an internal hernia may be localized, with transmesenteric: transmesocolic (8%) and transomental (1-4%) as the rarest. We report a series of two cases (men with 40 years-...

Upper limb vascular mapping with Doppler ultrasound: Technique precision evalua...

Introduction: Doppler ultrasound is recommended by international societies for preoperative vascular mapping in vascular access surgery. Literature is scarce regarding data on Doppler ultrasound-associated errors. Objectives: Our aim was to evaluate Doppler ultrasound precision for upper limb vascular mapping. Methods: Fifty-two adult healthy volunteers were evaluated for superficial vein diameter, brachial art...

Unclassified autoimmune pancreatitis mimicking pancreatic cancer

A 24-year-old black male presented with a 1-week obstructive jaundice and intermittent abdominal pain, with no significant weight loss and an unsuspicious abdominal exam. Blood chemistry showed a cholestatic pattern but a complete immunological and tumoral panel (anti-smooth muscle antibody, anti-mitochondrial antibody, anti-nuclear antibody, anti-neutrophil cytoplasmic antibody, anti-Smith, anti-double-strande...

Supralevator abscess: New treatment for an uncommon aetiology: Case report

Abstract INTRODUCTION: Supralevator abscess is the least common type of anorectal abscess. Its diagnosis can be hard and treatment difficult. PRESENTATION OF THE CASE: A 48-year-old men was diagnosed in the emergency department with a supralevantor abscess. Under general anaesthesia, the abscess drainage was accomplished after removal of a fish bone, who was perforating the rectum. Due to persistent rectal puru...

Acto-myosin force organization modulates centriole separation and PLK4 recruitm...

The presence of aberrant number of centrioles is a recognized cause of aneuploidy and hallmark of cancer. Hence, centriole duplication needs to be tightly regulated. It has been proposed that centriole separation limits centrosome duplication. The mechanism driving centriole separation is poorly understood and little is known on how this is linked to centriole duplication. Here, we propose that actin-generated ...

Inferences on specificity recognition at the Malus×domestica gametophytic self-...

In Malus × domestica (Rosaceae) the product of each SFBB gene (the pollen component of the gametophytic self-incompatibility (GSI) system) of a S-haplotype (the combination of pistil and pollen genes that are linked) interacts with a sub-set of non-self S-RNases (the pistil component), but not with the self S-RNase. To understand how the Malus GSI system works, we identified 24 SFBB genes expressed in anthers, ...

On the utility of 3D hand cursors to explore medical volume datasets with a tou...

Analyzing medical volume datasets requires interactive visualization so that users can extract anatomo-physiological information in real-time. Conventional volume rendering systems rely on 2D input devices, such as mice and keyboards, which are known to hamper 3D analysis as users often struggle to obtain the desired orientation that is only achieved after several attempts. In this paper, we address which 3D an...

Amputação abdominoperineal extraelevador – Revisão

Desde a descrição da Excisão Total do Mesorecto (ETM), a taxa de recidiva local da neoplasia do recto submetida a ETM decresceu consideravelmente para valores entre os 5 e 15%. No entanto, no que diz respeito à neoplasia do recto tratada cirurgicamente com amputação abdominoperineal (AAP), esta taxa manteve-se na ordem dos 40%. Os fatores identificados como responsáveis por estes piores resultados oncológicos f...

Actinomycosis Causing Recurrent Perianal Fistulae

Actinomycosis is a rare but easily curable infection that should be considered in the differential diagnosis of perianal fistulizing disease. We present the case of a 26-year-old woman with complex perianal fistulae, including trans-sphincteric and suprasphincteric fistulous tracts and a rectovaginal fistula, requiring multiple abscess drainages, seton placement, and antibiotic courses, with little improvement....
