Background: Porcine ulcerative dermatitis syndrome (PUDS) is a rare disease of breeding sows with an unknown pathogenesis.
Objective: To describe the evolution of clinical and histopathological lesions over the course of the disease and to elucidate the pathogenesis.
Animal: A 24-month-old, pluriparous, large white sow presented during gestation with ulcerations around the teats compatible with PUDS.
Methods And Results: Clinical and histopathological lesions were monitored over the course of the disease (i.e. during and after the subsequent pregnancy). A clear gestation-dependent flare of the lesions was observed with partial resolution occurring postpartum. The histological pattern presented as a lymphocytic interface dermatitis.
Conclusions And Clinical Importance: The findings in this case report link gestation with the development of clinical signs and histological changes. Multiparity appears to enhance severity and may finally result in a self-perpetuating disease. Therefore, it seems advisable to cull breeding sows after they have developed PUDS.

A newly developed articulated through-the-scope traction device, TRACMOTION, has been used clinically for endoscopic submucosal dissection (ESD). However, there are few reports on the characteristics of this device and the lesion types for which it is most effective. Therefore, we evaluated its optimal use, efficacy, and safety clinically in animals.

Real-world data are a highly valuable resource in determining the efficacy of novel products in challenging populations, especially in wound care. This study retrospectively analyzed the real-world performance of porcine placental extracellular matrix (PPECM; InnovaMatrix® AC, Convatec Triad Life Sciences, LLC, Memphis, TN, USA), a novel cellular, acellular, and matrix-like product for the management of hard-to-heal wounds. The US Wound Registry (USWR), which comprises aggregated and structured electronic health records from 502 wound practices, provided a deidentified dataset collected from October 10, 2022 to March 25, 2024, containing 76,278 patients (248,278 wounds).

Article Synopsis
- Transcriptome analysis of diabetic foot ulcers (DFUs) was conducted using mRNA sequencing to understand the microenvironment changes during wound healing in five patients.
- Wound specimens were collected at initial healing (0%) and after 50% healing, revealing 4,347 differentially expressed genes, predominantly linked to biological processes like cell adhesion and skin barrier formation.
- The study concluded that effective DFU healing is influenced by various factors, particularly inflammation control, angiogenesis, and the proliferation of fibroblasts.
Case report: Complications after using the "blind-stitch" method in a dairy cow with a left displaced abomasum: treatment, outcome, and economic evaluation.

Article Synopsis
- - A 4th lactation dairy cow had complications after an unsuccessful treatment for a left displaced abomasum (LDA) using the "blind-stitch" method, leading to abnormal health signs and inflammation at the incision site.
- - After administering antibiotics and fluids, the cow underwent a laparotomy and omentopexy surgery to resolve adhesion issues, and was monitored before being discharged two weeks later.
- - The cow produced 18,000 kg of milk post-treatment, with total costs for both interventions at 1,207 €, alongside an estimated revenue loss of 4,168 € due to complications, highlighting the need for careful method selection for LDA corrections.
