Use of Cell-Free DNA Testing to Diagnose Infective Endocarditis in a Patient With Negative Blood Cultures.

Infective endocarditis (IE) is associated with significant morbidity and mortality. Its diagnosis can be especially challenging, as can the identification of a causative pathogen, which, in turn, is crucial for appropriate management. Here, we present a rare case of Streptococcus intermedius endocarditis complicated by lung and cerebral abscess in which clinicians employed cell-free deoxyribonucleic acid (cfDNA) testing to confirm the diagnosis, establish a causative pathogen, and determine appropriate antibiotic therapy.

Capnocytophaga sputigena Tonsillitis in a Patient With Acute Myeloid Leukemia.

is a gram-negative facultatively anaerobic, capnophilic bacterium typically residing in the human oropharyngeal flora. This opportunistic pathogen can cause a wide range of infections, from bacteremia to septic abortion. However, it is exceedingly rare for a patient to present with tonsillitis due to .

A Rare Case of a Morel-Lavallée Lesion Complicated by Pseudomonas aeruginosa Infection: Diagnostic Challenges and Therapeutic Considerations.

Morel-Lavallée lesions are uncommon soft tissue injuries resulting from trauma, characterized by the separation of subcutaneous tissue from the underlying fascia. Soft tissue infections with are rare and most typically associated with hospital-acquired infections and burn wounds. This case report is regarding a 57-year-old man following a motorcycle accident who presented with a unique occurrence of an MLL complicated by infection.

A Rare Case of Herpes Simplex Virus and Cytomegalovirus Dual Infection Inducing Unremitting Ulcerative Colitis.

Ulcerative colitis (UC) is a subtype of inflammatory bowel disease that results in inflammation and ulceration in the lining of the large intestine. Patients with UC are frequently prescribed immunosuppressive medications to treat their symptoms, resulting in an increased risk of reactivation of many latent viruses, including herpes simplex virus (HSV) and cytomegalovirus (CMV). However, it is rare for a patient to present with simultaneous reactivation of both viruses.

Operative challenges of intramedullary nailing for subtrochanteric blastic pathological femur fracture: a case report.

Prostate adenocarcinoma metastasizes to bone and forms fragile blastic lesions, which can present as dense obstacles intraoperatively. There are limited reports on the challenges surgeons face when operating through these lesions. A 60-year-old male with a pathologic subtrochanteric femur fracture in the presence of blastic lesions was successfully treated with intramedullary (IM) fixation.

Peptide Drug Conjugates and Their Role in Cancer Therapy.

Drug conjugates have become a significant focus of research in the field of targeted medicine for cancer treatments. Peptide-drug conjugates (PDCs), a subset of drug conjugates, are composed of carrier peptides ranging from 5 to 30 amino acid residues, toxic payloads, and linkers that connect the payload to the peptide. PDCs are further broken down into cell-penetrating peptides (CPPs) and cell-targeting peptides (CTPs), each having their own differences in the delivery of cytotoxic payloads.
