Background: USA300 methicillin-resistant Staphylococcus aureus (MRSA) is a community- and hospital-acquired pathogen that frequently causes infections but also can survive on the human body asymptomatically as a part of the normal microbiota. We devised a comparative genomic strategy to track colonizing USA300 at different body sites after an initial infection. We sampled ST8 S. Read More

Purpose: Sentinel lymph node (LN) dissection (sLND) using a magnetometer and superpara-magnetic iron oxide nanoparticles (SPION) as a tracer was successfully applied in prostate cancer (PCa). The feasibility of sentinel LN (SLN) visualization on MRI after intraprostatic SPION injection has been reported. In the present study, results of preoperative MRI identification of SLNs and the outcome of subsequent intraoperative magnetometer-guided sLND following intraprostatic SPION injection were studied in intermediate- and high-risk PCa.

Endoscopic colorectal tattooing with carbon-based dyes is commonly employed in order to assist with later localization of the lesion. Although carbon is thought to be nontoxic, there usually is some inflammatory reaction with fibrosis and granuloma formation after tissue injection. The aim of this report is to alert to a possible underestimated, late consequence of colorectal carbon-based marker tattooing, namely pronounced fibrosis at the site of the injection that could lead to a blurring and misinterpretation of changes evaluated by radiological techniques.

Perianal abscess and fistula-in-ano are well-described in the pediatric population. They are most common in infants less than 1 year of age and often resolve with oral antibiotics; occasionally they require drainage or fistulotomy. The etiology is commonly associated with cryptoglandular obstruction and subsequent infection, however alternative diagnoses should be considered in cases of recurrent abscesses and fistulae that are refractory to standard treatments.

Standard-of-care imaging for initial staging of prostate cancer (PCa) underestimates disease burden. Prostate-specific membrane antigen (PSMA) PET/CT detects PCa metastasis with superior accuracy, having a potential impact on the planning of definitive radiation therapy (RT) for nonmetastatic PCa. Our objectives were to determine how often definitive RT planning based on standard target volumes covers Ga-PSMA-11 PET/CT-defined disease and to assess the potential impact of Ga-PSMA-11 PET/CT on definitive RT planning.

Traditionally rectal symptoms following pelvic/prostate radiotherapy are correlated to the dosimetry of the anorectum or a substructure of this. It has been suggested that the perirectal fat space (PRS) surrounding the rectum may also be relevant. This study considers the delineation and dosimetry of the PRS related to both rectal bleeding and control-related toxicity. Read More

A 58-year-old man with Gleason 4+3 prostate cancer was initially treated by radical prostatectomy followed by salvage radiotherapy to the prostate bed for postoperative biochemical failure. One year later, F-fluorocholine PET/CT detected a pelvic lymph node recurrence, which was treated with radiation therapy and 6 months of androgen deprivation.

Target volume delineations for prostate cancer (PCa) salvage radiotherapy (SRT) after radical prostatectomy are usually drawn in the absence of visibly recurrent disease. Ga-labeled prostate-specific membrane antigen (PSMA-11) PET/CT detects recurrent PCa with sensitivity superior to standard-of-care imaging at serum prostate-specific antigen (PSA) values low enough to affect target volume delineations for routine SRT. Our objective was to map the recurrence pattern of PCa early biochemical recurrence (BCR) after radical prostatectomy with Ga-PSMA-11 PET/CT in patients with serum PSA levels of less than 1 ng/mL, determine how often consensus clinical target volumes (CTVs) based on the Radiation Therapy Oncology Group (RTOG) guidelines cover Ga-PSMA-11 PET/CT-defined disease, and assess the potential impact of Ga-PSMA-11 PET/CT on SRT.
