Assessing asymmetrical kidney function in living donors: a retrospective cohort study on CT metrics.

Background: Live donor kidney transplantation is the preferred kidney replacement therapy for eligible patients but requires thorough donor evaluation to minimise risks. Contemporary guidelines recommend split kidney function measurement in living donors only when there is a significant kidney size discrepancy, yet the evidence for this is poor, and practice varies nationally. This study evaluates the efficacy of CT-derived kidney metrics in detecting significant functional asymmetry.

Cocaine-induced granulomatosis with polyangiitis-an under-recognized condition.

Objectives: Cocaine and cocaine mixed with levamisole are increasingly used in the UK and result in significant direct nasal damage in addition to promoting vasculitis. Our aims were as follows: (1) to identify the main symptoms and presentation of cocaine-induced vasculitis; (2) to provide evidence regarding the best practice for the investigation and diagnosis of cocaine-induced vasculitis; and (3) to analyse the clinical outcomes of patients in order to understand the optimal management for the condition.

Methods: We performed a retrospective case series analysis of patients presenting with cocaine-induced midline destructive lesions or vasculitis compatible with granulomatosis with polyangiitis (GPA) from two large tertiary vasculitis clinics between 2016 and 2021.

Pre-treatment clinical assessment in head and neck cancer: United Kingdom National Multidisciplinary Guidelines.

This is the official guideline endorsed by the specialty associations involved in the care of head and neck cancer patients in the UK. This paper provides recommendations on the pre-treatment clinical assessment of patients presenting with head and neck cancer. Recommendations • Comorbidity data should be collected as it is important in the analysis of survival, quality of life and functional outcomes after treatment as well as for comparing results of different treatment regimens and different centres.

Hyperventilation-related hyperlactataemia in a case of paroxysmal vocal cord dysfunction.

Paroxysmal Vocal Cords Dysfunction(PVCD), also known as paradoxical vocal cord motion, is abnormal adduction of the vocal cords during inspiration. Like asthma, PCVD can be triggered by breathing in lung irritants, upper respiratory infection or exercise. However, unlike asthma, PCVD is not an immune system reaction and does not involve the lower airways.
