The wonders of the animal kingdom make an absorbing reappearance this episode, so grab your scuba mask before listening - or your chef’s hat.

The first case this month is the kind that even an experienced neurologist would be nervous to encounter (1:35). A holidaymaker in his sixties presents to the emergency department with vomiting, dizziness, and an inability to walk, amongst several other symptoms. A suspicion of stroke was quickly replaced by a different hypothesis following discussions with the patient’s family members.

The second case follows a presentation over the span of multiple decades (18:44). A woman first presents in her thirties with extreme lethargy and occasional migraines. She was diagnosed with panhypopituitarism and treated with steroid replacement. Following breast cancer in her late forties, treated by surgery and radiotherapy, the migraines worsened, prompting further investigation.

The case reports discussion is hosted by Prof. Martin Turner¹, who is joined by Dr. Ruth Wood² and Dr. Babak Soleimani³ for a group examination of the features of each presentation, followed by a step-by-step walkthrough of how the diagnosis was made. These case reports and many others can be found in the June 2025 issue of the journal.

"This is a disorder that you don't want to miss", says Prof. Jon Stone¹, describing the condition at the heart of this episode, alongside co-author Dr. Huw Green². Their paper "Health anxiety in a neurological setting" is the subject of the Editors' Choice podcast for the August 2025 issue, hosted by Dr. Amy Ross Russell. They cover the assumptions to avoid, the problematic pattern of patient reassurance and return, effective treatment methods, and even touch on a light bit of existentialism.

Gastric sleeve surgery is the key feature of a pair of recent cases from the journal, which start this episode (1:17). Both cases feature 25-yo women with presentations in common: paraesthesia and limb weakness, along with disordered eye movement. Their symptoms arose soon after the gastrectomy operation. https://pn.bmj.com/content/25/3/268

The second report is a "true grey case" (22:14), with a myriad of presenting symptoms in a 27-yo man: fevers, weight loss, lethargy, light sensitivity, and skin plaques around the nose and mouth. Steroid treatment was started with a suspicion of a  connective tissue disease, but was halted when his condition soon worsened. Some feathered friends of the podcast shine a light on the diagnosis. https://pn.bmj.com/content/25/3/253

This episode’s theme is new diseases, whether they are newly described, or old diseases back in a new form. We start off with IgG4-related disease, a chronic multisystem disorder that is still being understood. Then there is a genetics paper on repeat expansion disorders, a group of conditions often thought as disparate but with quite a few commonalities. Next along is a fascinating case following gastric sleeve bariatric surgery, highlighting the dangers of travelling for unsupervised surgeries, and raising the question, “Are you getting enough soil in your diet?” There’s also a discussion of what else Hoover’s sign might represent, and the evolution of immunoglobulin use. Closing the episode is a paper offering a masterclass on the assessment of best interests in  prolonged disorder of consciousness.

Two wide open cases from the latest issue of the journal. Starting with a case from Italy (1:18), of a 63-yo man having a history of behavioural and cognitive problems since retiring. His many changes included low mood, significant weight loss, and problems with sleep and temperature regulation. He had a background of type 2 diabetes. Initial treatment was on a suspicion of Alzheimer's, but there was no clinical improvement. https://pn.bmj.com/content/25/2/159

A case from the United States is next (17:36), featuring a 66-yo lady experiencing 10 days of generalised weakness, with episodes of forgetfulness and a series of falls. She had previously been treated for left-sided ophthalmic herpes zoster. Neurological examination showed mild right arm and leg weakness. https://pn.bmj.com/content/25/2/164

The case reports discussion is hosted by Prof. Martin Turner¹, who is joined by Dr. Ruth Wood² and Dr. Babak Soleimani³ for a group examination of the features of each presentation, followed by a step-by-step walkthrough of how the diagnosis was made. These case reports and many others can be found in the April 2025 issue of the journal.
