High-Risk Melanoma: Stage Before Operating.

Current NICE guidelines state that in high-risk melanoma patients, imaging should not be offered before SLNB unless lymph node or distant metastases are suspected. Our experience has been that in patients with pT3b, pT4a and pT4b melanomas, the rate of management-changing findings on axial imaging prior to SLNB was high and that 'stage before operating' is a better approach. We now offer full axial imaging as staging to all high-risk melanoma patients prior to SLNB and advise other skin cancer MDTs to follow this approach.

Using X-ray velocimetry to measure lung function and assess the efficacy of a pseudomonas aeruginosa bacteriophage therapy for cystic fibrosis.

Phase contrast x-ray imaging (PCXI) provides high-contrast images of weakly-attenuating structures like the lungs. PCXI, when paired with 4D X-ray Velocimetry (XV), can measure regional lung function and non-invasively assess the efficacy of emerging therapeutics. Bacteriophage therapy is an emerging antimicrobial treatment option for lung diseases such as cystic fibrosis (CF), particularly with increasing rates of multi-drug-resistant infections.

Cerebrospinal fluid diversion prior to posterior fossa tumor resection in adults: A systematic review.

Background: Posterior fossa tumors (PFTs) comprise 15%-20% of adult brain tumors, with the reported frequency of hydrocephalus (HCP) ranging between 3.7% and 58%. Most HCP resolves after resection of PFTs, but studies report persistent or new-onset HCP occurring in between 2% and 7% of cases.

Spontaneous Cerebrospinal Fluid Rhinorrhea in Pre-operative Pituitary Adenoma: A Report of Two Cases.

Pituitary macroadenomas are neuroendocrine tumors residing in the base of the skull. First-line therapies for prolactin-secreting adenomas (prolactinoma) include medical treatment with dopamine agonists and neurosurgical intervention. Cerebrospinal fluid (CSF) rhinorrhea is a well-known complication following skull base tumor treatment; however, spontaneous CSF rhinorrhea as the initial presenting feature of such tumors is rare.
