While arteriovenous fistulas (AVFs) are the optimal route of access for hemodialysis in terms of duration of patency and infection rates, they can still fail due a variety of reasons. Most commonly, AVF failure is due to venous stenotic lesions, resulting in reduced blood flow rate across the fistula. Fistulograms are often used to investigate cases of symptomatic or poor fistula function. This case discusses a 71-year-old man with a mature brachiocephalic AVF who presented with severe right upper extremity edema, and had a negative fistulogram, despite a severe stenosis in his AVF.

Fatal Delayed Cardiac Tamponade Following Atrial Fibrillation Ablation: A Case Report.
Cureus
December 2024
Internal Medicine, Hurley Medical Center, Flint, USA.
Catheter ablation procedure for symptomatic atrial fibrillation is an established treatment. Cardiac tamponade is one of the several complications associated with atrial fibrillation ablation. We present the case of a 60-year-old male with a past medical history of end-stage renal disease (ESRD) on hemodialysis, hypotension on midodrine, atrial fibrillation status post-ablation a week prior, and a cerebrovascular accident who presented to the emergency department with complaints of weakness, nausea, vomiting, confusion and some syncopal episodes for the past few days.

Persistent hiccups are rare but can serve as an early symptom of underlying conditions, including pulmonary infections and cerebrovascular disorders. This case highlights hiccups as a presenting symptom of bronchopneumonia in a hemodialysis patient and explores the effective use of chlorpromazine and Hange-koboku-to (HKT) as symptomatic therapies. Given the potential association of hiccups with neurological conditions, this case underscores the need for comprehensive diagnostic evaluation.

Article Synopsis
- Leontiasis ossea, or craniofacial fibrous dysplasia, is a rare condition that causes abnormal growth of facial bones, often linked to chronic kidney disease and high parathyroid hormone levels.
- A case of a 30-year-old male with severe facial swelling and bone changes highlights the rapid progression of symptoms after poor dialysis access and the persistence of hyperparathyroidism despite treatment efforts.
- The article also reviews the underlying causes, imaging techniques used for diagnosis, and management strategies for this complex disease.
Calciphylaxis: A Case Report and Review of the Role of Sodium Thiosulphate and Other Treatment Modalities.

November 2024
Nephrology, Colchester Hospital, Colchester, GBR.
Calciphylaxis is a rare and serious disorder almost exclusively seen in patients on dialysis or those with advanced chronic kidney disease (CKD) not on dialysis and is associated with very high mortality. We present the case of a 50-year-old male with a background of end-stage renal disease (ESRD) compliant with dialysis, parathyroid adenoma, secondary hyperparathyroidism, and high body mass index (BMI). Whilst receiving 31 doses of intravenous sodium thiosulphate (STS) over an 11-week period, the patient underwent surgical debridement of multiple painful ulcerative lesions in his lower abdomen and left thigh and then subsequently a subtotal parathyroidectomy at 70 days from admission.

BACKGROUND Toluene poisoning can occur as a result of occupational exposure in industries such as painting, as well as through misuse, leading to complications such as neurological symptoms due to the accumulation of the metabolic byproduct of hippuric acid and metabolic acidosis. However, the exact mechanisms remain unclear. Hippuric acid is not removed by dialysis, so urinary excretion plays a central role.
