The results of the analysis of 1209 serum samples, made with a view to detecting those containing HBsAg, are presented. This analysis was made by the radioimmunoassay (RIA) on a polyethylene film, by the standard RIA technique with the use of a diagnostic kit obtained from Abbott Laboratories (USA) and by the passive hemagglutination (PHA) test. The RIA film technique was found to have the sensitivity of about 2 ng/ml HBsAg, which is similar to the sensitivity of the kit from Abbott Laboratories and exceeds the sensitivity of the PHA test approximately 50-fold. The percentage of detected HBsAg-positive sera, yielded by analysis with the use of the RIA film technique and the standard RIA technique, is the same. The RIA technique make it possible to detect more positive sera than the PHA test by about 2.5%.

Objective: Patient characteristics, iodine injection, and scanning parameters can impact the quality and consistency of contrast enhancement of hepatic parenchyma in CT imaging. Improving the consistency and adequacy of contrast enhancement can enhance diagnostic accuracy and reduce clinical practice variability, with added positive implications for safety and cost-effectiveness in the use of contrast medium. We developed a clinical tool that uses patient attributes (height, weight, sex, age) to predict hepatic enhancement and suggest alternative injection/scanning parameters to optimize the procedure.

Background: Mucopolysaccharidosis (MPS) type 1 S and type 2 are rare lysosomal storage disorders characterized by impaired enzyme production, resulting in glycosaminoglycans accumulation within lysosomes. Enzyme Replacement Therapy (ERT) with laronidase and idursulfase are first line treatments, respectively. However, infusion-related hypersensitivity reactions (HR) may lead to ERT discontinuation.

Background: Hypersensitivity reactions to chemotherapy disrupt treatment schedules and compromise patient outcomes. Rapid Drug Desensitization (RDD) enables patients to tolerate future treatments after an allergy workup. However, Same-Day Desensitization (SDD) is a novel approach that capitalizes on RDD to allow the continuation of chemotherapy on the same day as the index reaction, preventing treatment delays.
