Advanced tumour-induced osteomalacia secondary to sinonasal phosphaturic mesenchymal tumour.

Unlabelled: Phosphaturic mesenchymal tumours (PMT) are rare, benign lesions and the most common tumour to cause tumour-induced osteomalacia (TIO), a paraneoplastic syndrome. Patients frequently exhibit severe osteomalacia, accompanied by multiple fractures, which significantly impair their quality of life. Complete surgical resection is curative.

The impact of physiological state and environmental stress on bacterial load estimation methodologies for Mycobacterium tuberculosis.

When processed in solid or liquid medium, tuberculosis patient samples yield different proportions of a heterogenous bacterial community over the duration of treatment. We aimed to derive a relationship between methodologies for bacterial load determination and assess the effect of the growth phase of the parent culture and its exposure to stress on the results. Mycobacterium tuberculosis H37Rv was grown with and without antibiotic (isoniazid or rifampicin) and sampled on day 0, 3, 11 and 21 of growth in broth culture.

Development and validation of an innovative administration system to facilitate controlled holmium-166 microsphere administration during TARE.

Background: To develop and validate a novel administration device for holmium-166 transarterial radioembolisation (TARE) with the purpose of facilitating controlled fractional microsphere administration for a more flexible and image-guided TARE procedure.

Methods: A Controlled Administration Device (CAD) was developed using MR-conditional materials. The CAD contains a rotating syringe to keep the microspheres in suspension during administration.

Drugs in focus: Botulinum toxin in the therapy of gastrointestinal disorders in children.

What Is Known: Botulinum toxin (BoNT) causes muscle relaxation by inhibiting acetylcholine release from presynaptic motor neurons at the neuromuscular junction.

What Is New: In children with achalasia, BoNT can be considered only in patients in whom rapid weight gain is important to improve surgical outcomes. BoNT has been suggested for treating cricopharyngeal achalasia and delayed gastric emptying.

White matter integrity in hospitalized COVID-19 patients is not associated with short- and long-term clinical outcomes.

Objectives: SARS-CoV-2 infection is associated with a decline in functional outcomes; many patients experience persistent symptoms, while the underlying pathophysiology remains unclear. This study investigated white matter (WM) integrity on brain MRI in hospitalized COVID-19 patients and its associations with clinical outcomes, including long COVID.

Materials And Methods: We included hospitalized COVID-19 patients and controls from CORONavirus and Ischemic Stroke (CORONIS), an observational cohort study, who underwent MRI-DWI imaging at baseline shortly after discharge (<3 months after positive PCR) and 3 months after baseline scanning.
