Herpes zoster (HZ) infection occurs in approximately 10% to 30% of individuals. Visceral neuropathies secondary to HZ can cause cystitis and urinary retention. But colonic pseudo-obstruction can also occur. Peripheral neuropathy may reveal segmental motor paresis of either upper or lower limbs, the abdominal muscles or the diaphragm. We report the case of a 62-year-old male patient who presented with abdominal distention and cutaneous vesicular eruption on the left side of the abdominal wall. Plain X-rays and computed tomography scan showed distended small bowel. A diagnosis of intestinal pseudo-obstruction was made secondary to segmental paresis of the small intestine and visceral neuropathy. Conservative management was successful and the patient was discharged uneventfully. Intestinal pseudo-obstruction ought to be considered when dealing with non-obstructive (adynamic) conditions of the digestive tract associated with HZ infection; since early recognition may help to avoid unnecessary surgery.

Polydactyly, hypopigmentation, and squamous cell carcinoma are common in cats. However, a cat exhibiting all of these conditions has not yet been reported. This study presents the case of a 14-year-old male Mexican cat, hypopigmented, with supernumerary fingers, two preaxial and one on each posterior limb, admitted to the clinic with a lesion in the left periocular region. The cat was subjected to a general physical examination, blood, and urine chemistry, as well as a biopsy and genomic instability assessment with an analysis of the red blood cells (RBC) micronucleated erythrocytes (RBC-MNE) in the peripheral blood. The biopsy was positive for squamous cell carcinoma, and the RBC-MNE count (8.6 MNE/1000 erythrocytes) was high compared to that previously described in other domestic cats or wild cats. Thus, the genomic instability of the RBC-MNE could be used as an indicator to identify clinical conditions of felines, particularly those with one of the characteristics exhibited by this Mexican cat. The RBC-MNE test is the most widely used in the world for the evaluation of DNA damage, but to our knowledge, it has not been used to identify vulnerable non-human specimens.

INTRODUCCIÓNEl síndrome de dificultad respiratoria aguda por coronavirus 2 (SARS-CoV-2) es una complicación ocasionada por la enfermedad altamente transmisible por coronavirus 19 (COVID-19). Las manifestaciones clínicas por COVID-19 pueden variar de asintomático a síndrome de dificultad respiratoria que requiere ventilación invasiva. Los pacientes que tienen mayor riesgo de complicaciones son los que cuentan con comorbilidades que influyen en su estado de salud. 1 Los tumores primarios de la pared torácica (TPPT) son infrecuentes, conforman el 5-10% de las neoplasias primarias del tórax y se originan de cualquier elemento nativo del hueso y de las partes blandas. 2 Alrededor de 50% de los tumores torácicos son de www.medigraphic.com/cirugiatoracica

La articulación de Chopart está formada por las articulaciones astrágalo-escafoidea y calcáneocuboidea. Ambas articulaciones interactúan estrechamente entre sí y con la articulación subastra-galina dentro del complejo de la triple articulación. 1,2 En consecuencia, el mal funcionamiento de una articulación afectará negativamente a las otras dos articulaciones, lo que limitará sustancialmente la función global del pie. Tanto la articulación astrágalo-escafoidea como la calcáneo-cuboidea están estabilizadas por fuertes CASO CLÍNICO
