Successful Treatment of Lomentospora Prolificans Infection Following Allogeneic Hematopoietic Stem Cell Transplantation: A Case Report and Literature Review.

Lomentospora prolificans is an opportunistic fungal pathogen known for its intrinsic multidrug resistance. This pathogen poses a significant challenge in immunocompromised individuals, particularly patients with hematologic malignancies. We present a case of a 27-year-old male diagnosed with adverse-risk acute myeloid leukemia (AML) who developed pulmonary Lomentospora prolificans infection following therapy for positive measurable residual disease (MRD) and severe chronic graft-versus-host disease (cGVHD) after allogeneic hematopoietic stem cell transplantation (allo-HSCT).

Weightbearing Computed Tomography (WBCT) Analysis of Subtalar Joint Dynamics in Hindfoot Valgus Malalignment.

Hindfoot valgus malalignment, characterized by the lateral deviation of the calcaneus and medial tilting of the talus, disrupts hindfoot biomechanics and increases strain on subtalar joint. This study evaluates weightbearing and non-weightbearing imaging modalities to identify dynamic alignment changes and their diagnostic implications. This study aims to (1) quantify changes in subtalar joint parameters between non-weightbearing computed tomography (NWBCT) and weightbearing computed tomography (WBCT) in patients with hindfoot valgus; (2) evaluate correlations between WBCT and standard radiographic parameters; and (3) identify radiographic predictors of subtalar joint status during weightbearing.

Weight-Bearing CT: Advancing the Diagnosis and Treatment of Hallux Valgus, Midfoot Pathology, and Progressive Collapsing Foot Deformity.

Since its introduction, weight-bearing computed tomography (WBCT) has gained prominence due to its ability to produce accurate three-dimensional images under natural loading conditions, making it particularly useful for assessing complex foot deformities. This review aimed to focus on the diseases of the foot and categorized the pathological conditions into forefoot disease (hallux valgus), midfoot disease (Lisfranc injuries and midfoot osteoarthritis), and progressive collapsing foot deformity. For each category, the authors detail how WBCT enhances diagnostic accuracy and informs treatment strategies.

A Neglected Extensor Hallucis Longus Tendon Rupture Caused by Arthritic Adhesion.

Extensor hallucis longus tendon injury is relatively rare and is principally caused by a laceration when a sharp object is dropped on the instep. Primary suturing is possible if the injury is acute, but if the tear is chronic, tendon contracture causes the space between the edges of the tear to widen, disrupting the end-to-end connection. In particular, a claw toe or checkrein foot deformity may develop over time due to adhesion of the lower leg tendons near the fracture site or scar.
