Evaluation of Selective Culling as a Containment Strategy for African Swine Fever at a Vietnamese Sow Farm.

Selective culling, also known as the "tooth extraction approach", is a strategy for controlling African swine fever (ASF) by removing only sick and suspect animals instead of the entire herd in Vietnam. This method prioritizes preserving healthy animals, particularly valuable breeding pigs. Despite its implementation in various forms, no standardized protocol based on scientific principles has been established. Farms typically adapt this strategy based on their understanding, which can vary significantly. In implementing of selective culling that is not based on scientific principles, there is a significant risk of spreading the disease. The aim of this study is to evaluate the consequences of selective culling as currently implemented in Vietnam. Our analysis on a large sow farm revealed that current practices rely heavily on clinical observations without laboratory confirmations. This approach allows ASF-infected animals to remain on the farm longer, potentially exacerbating the spread of the virus. Thus, selective culling poses a substantial risk by potentially exacerbating the spread of disease. Our findings emphasize that early diagnosis of ASF and systematic removal of infected pigs are critical components for the effective implementation of selective culling strategies and that a high level of fragmentation to minimize contact between animals plays a key role. The optimal approach is to test conspicuous animals and separate them. Under no circumstances should suspect animals be left in the herd for several days before they become severely ill and succumb to the disease.

Transarterial doxorubicin-eluting beads embolization for the treatment of desmoid fibromatosis in the pubic region.

Desmoid fibromatosis (DFs) is rare, low-grade neoplasm. Although it poses no risk of metastasis, DFs exhibits a range of clinical manifestations characterized by local infiltrative growth tendencies and a propensity for recurrence. Despite its nonmalignant nature, DFs can be highly debilitating and occasionally life-threatening, causing severe pain and functional limitations. Traditionally, surgery served as the conventional primary treatment approach; nevertheless, a recent shift in paradigm towards a more conservative management has emerged, accompanied by efforts to standardize the strategy among clinicians. Systemic doxorubicin has been demonstrated to be effective in treating DFs; however, it carries potential risks of adverse effects on the cardiovascular, digestive, and hematologic systems. The novel intravascular intervention employing drug-eluting beads loaded with doxorubicin represents an effective treatment for DFs, optimizing drug delivery to the target lesion and reducing systemic toxicity. In this article, we present a rare case of DFs in the right pubic region treated with transarterial doxorubicin-eluting beads embolization.
