Buschke-Löwenstein tumours (BLTs) are rare, sexually transmitted lesions associated with human papillomavirus (HPV) infections that primarily affect the perineal and genito-anal regions. Surgical excision is the standard treatment; however, management is often complicated by the tumour's local invasiveness, disease progression, variable treatment response, and high recurrence rates. Wound healing is especially challenging due to the proximity to perineal structures, increasing the risk of contamination and infection.

Pseudorabies virus (PRV) is a significant pathogen impacting swine health and poses high zoonotic risks to humans. Effective antiviral treatments for PRV remain limited, underscoring the need for novel therapeutic strategies. In this study, ciprofloxacin was identified as a repurposed promising candidate with significant in vitro inhibition of PRV replication based on our inference from PNU-183792, an HSV-1 DNA polymerase inhibitor, that quinolones have the potential to act as anti-PRV drugs.

Over 60% of breast cancer cases are diagnosed with estrogen-receptor (ER) positive. Tamoxifen (TAM), a commonly employed medication for ER-positive breast cancer, often yields suboptimal therapeutic outcomes due to the emergence of TAM resistance, leading to the recurrence and a poor prognosis. The copper transporter, solute carrier family 31 member 1 (SLC31A1), has been associated with tumor aggressiveness and unfavorable outcomes in various types of tumors.

Colonic tuberculosis (TB) is a rare form of extrapulmonary TB with nonspecific clinical presentations such as weight loss, abdominal pain and fever. It is often misdiagnosed, as the presentations mimic other more common diseases such as colon cancer and inflammatory bowel diseases, especially in those countries with low TB incidence. Although a combination of CT imaging, colonoscopy and histopathology forms the essential part of the diagnostic assessment, the high variability and low specificity of each investigation may delay or overlook the diagnosis.

Although different types of prognostic indices have been applied in extranodal NK-/T-cell lymphoma (ENKTL), they are based mainly on clinical characteristics before treatment. Moreover, these methods lack early assessment and tumor metabolic parameters. It remains unclear whether changes in the plasma Epstein-Barr virus DNA (EBVDNA) status and SUVmax after two cycles of chemotherapy may predict disease prognosis.
