Abstract  A case report of an 8-month-old ferret with severe ulcerative dermatitis of the ventral abdomen and medial thigh regions is presented. Cutaneous biopsies of the periphery of the ulcerative lesions revealed large, confluent, superficial epidermal pustules containing inflammatory cellular debris and Gram-positive cocci, as well as perifollicular dermal necrosis. These histological findings are consistent with superficial spreading pyoderma in conjunction with dermal coagulative necrosis. Résumé- Un furet mâle de 8 mois est présenté pour une dermite ulcérative sévère du ventre et des faces internes des cuisses. Des biopsies cutanées réalisées à la périphérie des lésions ulcératives montrent la présence d'importantes pustules épidermiques contenant des débris cellulaires inflammatoires et des bactéries cocci Gram positif, ainsi qu'une nécrose dermique périfolliculaire. Ces éléments histopathologiques sont en faveur d'une pyodermite superficielle extensive associée à une nécrose de coagulation du derme. [King, W. W., Lemarié, S. L., Veazey, R. S., Hodin, E. C.

El estudio de biopsias de la periferia de las zonas ulceradas reveló la presencia de grandes pústulas superficiales epidérmicas confluentes que contenían restos celulares inflamatorios y cocos Gram-positivo, así como necrosis perifolicular en la dermis.

Hautbiopsien aus der Peripherie der ulzerativen Veränderungen zeigten große, konfluierende, oberflächliche epidermale Pusteln, die entzündlichen Zelldebris und Gram-positive Kokken enthielten, sowie eine perifollikuläre dermale Nekrose. Diese histologischen Befunde stimmen mit der oberflächlich ausgebreiteten Pyodermie in Verbindung mit einer dermalen Koagulationsnekrose überein. [King, W. W., Lemarié, S. L., Veazey, R.

Circuit-based biomarkers distinguishing the gradual progression of Lewy pathology across synucleinopathies remain unknown. Here, we show that seeding of α-synuclein preformed fibrils in mouse dorsal striatum and motor cortex leads to distinct prodromal-phase cortical dysfunction across months. Our findings reveal that while both seeding sites had increased cortical pathology and hyperexcitability, distinct differences in electrophysiological and cellular ensemble patterns were crucial in distinguishing pathology spread between the two seeding sites.

Objective: Focal cortical seizures travel long distances from the onset zone, but the long-distance propagation pathways are uncertain. In vitro and in vivo imaging techniques have investigated the local spread of seizures but did not elucidate long-distance spread. Furthermore, classical studies in slices suggested seizure spread locally along deep cortical layers, whereas more recent in vivo imaging studies posit a role for superficial cortical layers in local spread.

Endoscopic submucosal dissection versus endoscopic mucosal resection for laterally spreading rectal tumours.

Colorectal Dis

December 2024

Service d'Hépato-gastroentérologie et Endoscopies Digestives, Hôpital Européen Georges-Pompidou, Assistance Publique Hôpitaux de Paris, Paris, France.

Aim: Endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD) are the two main techniques used for endoscopic resection of superficial rectal tumours. The aim of this study was to compare the outcomes of ESD and EMR in treating superficial rectal tumours.

Method: A retrospective observational study was conducted at two French centres including all patients treated with ESD or EMR for superficial rectal tumours.
