One center experience of pneumatosis cystoides intestinalis

2017

Introduction Pneumatosis cystoides intestinalis (PCI) is a rare benign condition, in which gas is found in a linear or cystic form in the subserosa or submucosa. The subserous cysts are most frequently found in the small bowel while the submucous localizations are predominantly seen in the colonic wall. Peritoneal pneumatosis, abdominal gas cysts, cystic lymphopneumatosis, intestinal emphysema or intestinal gas cysts are terms used to describe the occurrence of multiple, gas-filled cysts, of the gastrointestinal tract. Incidence of PCI was reported to be 0.03% in the general population. It is a radiographic finding and not a diagnosis, as the etiology varies from benign conditions to fulmin…

Diagnostic performance of endoscopic ultrasound through‐the‐needle microforceps biopsy of pancreatic cystic lesions: Systematic review with meta‐anal…

2020

Objectives Endoscopic ultrasound through-the-needle biopsy (EUS-TTNB) is a useful tool for differential diagnosis among pancreatic cystic lesions (PCLs). Cystic fluid cytology (CFC) is recommended by guidelines, but its diagnostic accuracy is about 50%. The aim of this meta-analysis is to assess the clinical impact of EUS-TTNB in terms of technical success (TS), histological accuracy (HA) and diagnostic yield (DY). Methods Original studies in English language on EUS-TTNB were searched in MEDLINE and EMBASE until October 2019. Diagnostic accuracy of EUS-TTNB for identification of mucinous PCLs was calculated using individual diagnostic data of patients who underwent CFC and surgery. Results …

Intermittent Horner's syndrome on alternate sides: a hint for locating spinal lesions.

1980

A patient with a cervical intramedullary ependymoma is described who exhibited a Horner's syndrome on alternate sides. Pharmacological study demonstrated damage to the pre-ganglionic sympathetic neurons. Disregarding cases with the Shy-Drager syndrome, three comparable case reports have been found in the literature where the fluctuating expression of Horner's syndrome, alternating from one side to the other, was attributable to a lesion of the cervical spinal cord. In contrast to the present patient, the pharmacological responses of these patients indicated a lesion of the central sympathetic pathway.

Presurgical role of MRI tractography in a case of extensive cervicothoracic spinal ependymoma

2017

Background: Intramedullary spinal ependymoma is a tumor, hardly characterizable with conventional magnetic resonance (MR) imaging only. MR diffusion tensor imaging (DTI) with three dimensional fiber tracking reconstructions allows the evaluation of the relationship between neoplasm and white matter fiber tracts, being a powerful tool in presurgical planning. We present DTI findings in a case of a young female with an extensive cervicothoracic spinal ependymoma. Case Description: The patient complained of a 2 month history of acute urinary retention, weakness and numbness on the lower limbs and the upper left limb. She underwent MR imaging that showed an extensive cervicothoracic spinal mass…

Retraction: Oral leukoplakia, a clinical-histopathological study in 412 patients

2021

The authors detected some minor errors in the published manuscript (Rubert A, Bagan L, Bagan JV. Oral leukoplakia, a clinical-histopathological study in 412 patients. J Clin Exp Dent. 2020 Jun 1;12(6):e540-e546. doi: 10.4317/jced.57091. PMID: 32665812; PMCID: PMC7335600.) and have requested that the entire article be republished with these errors already rectified. Background A retrospective clinical-histopathological study was made of the evolution of oral leukoplakia over time, staging the disease according to the classification of van der Waal. Material and methods A study was made of 412 patients with oral leukoplakia, analyzing the corresponding clinical factors and histopathological f…

Oral leukoplakia, a clinical-histopathological study in 412 patients

2020

Background A retrospective clinical-histopathological study was made of the evolution of oral leukoplakia over time, staging the disease according to the classification of van der Waal. Material and Methods A study was made of 412 patients with oral leukoplakia, analyzing the corresponding clinical factors and histopathological findings; assessing associations between the different clinical presentations and epithelial dysplasia; and evaluating the factors influencing malignant transformation of the lesions. Results Clinically, homogeneous presentations were seen to predominate (n = 336, 81.6%), while histologically most of the lesions exhibited no dysplastic changes (n = 271; 65.7%). Stage…

ANÁLISIS DE LA EJECUCIÓN DE LA ARRANCADA EN HALTEROFILIA: UNA REVISIÓN SISTEMÁTICA

2022

El propósito de este estudio es identi car, mediante una revisión sistemática, los parámetros clave en la ejecución de estos movimientos en términos de trayectoria ideal de la barra y parámetros cinemáticos como velocidad y aceleración en todo el recorrido. Para ello se han seleccionado 25 artículos cientí cos originales de las siguientes bases de datos: Google Scholar, PubMed, Dialnet y Scopus. Se encontró que existen tres posibles trayectorias de la barra con diferencias principalmente en la verticalidad de la barra en la fase ascendente y en el desplazamiento de los pies. Por otro lado, se determinó que la velocidad de la barra alcanzada al nal del primer tirón oscilaba ent…

Exposure to radial extracorporeal shockwaves induces muscle regeneration after muscle injury in a surgical rat model

2019

The leading cause of training interruption in sport is a muscle injury, for which the standard treatment is nonsteroidal anti-inflammatory drugs (NSAIDs). To find alternative treatments, we investigated whether the radial extracorporeal shockwave application (rESWT) could stimulate muscle regeneration. A lesion with complete rupture (grade III muscle tear) was set in the musculus rectus femoris of 12-week-old Wistar rats, and the NSAID diclofenac, rESWT, or a combined therapy were applied on day 0, 3, and 5 directly following the surgery. Rats were euthanized at 2, 4, and 7 days after surgery and the area of muscle lesion was excised for histological and gene expression analysis to determin…
