Flow cytometry is the gold standard for the detection of paroxysmal nocturnal hemoglobinuria (PNH) clones. Several antibody panels have been used with varying sensitivities and specificities. The CD157 is one of the glycosylphosphatidylinositol-anchored molecules tested and widely used. The CD157 deficiency is rare. We report a case of an isolated CD157 deficiency discovered during the search for the PNH clone in a patient with a plastic anemia. The interpretation of the results in this case poses a problem of false positive. We discuss how to deal with these difficulties encountered by the biologist, detailing the various possible causes. This observation also underlines the importance of following international guidelines before making the diagnosis of the PNH clone which has significant implications.

Tic douloureux, also known as trigeminal neuralgia, is distinguished by recurrent episodes of severe, lancinating pain that affects one or more branches of the trigeminal nerve, representing a prevalent pain syndrome. This condition has an annual incidence rate of 27 per 100,000 individuals. Nevertheless, direct compression caused by vertebrobasilar dolichoectasia (VBD) represents a considerably less frequent etiology of trigeminal neuralgia, with an estimated overall incidence of about 1%.

Magnusiomyces capitatus is an environmental fungus found in soil, water, air, plants, and dairy products which may cause opportunistic infections in patients with haematological disorders resulting in high mortality rates. This series of the first reported cases in Ireland discusses investigation of two patients with underlying haematological disorders, hospitalised in the Irish National Adult Stem Cell Transplant Unit (NASCTU), who developed line-related fungaemias with M. capitatus within a three-month period.

We aimed to assess the uric acid-to-high-density lipoprotein cholesterol (HDL-C) ratio (UHR) and several other parameters with respect to their performance in detecting recurrence among patients with atrial fibrillation (AF) who underwent ablation. This retrospective cohort study analyzed data from patients who underwent radiofrequency or cryoablation for paroxysmal, persistent, or long persistent AF between September 2021 and September 2023. After ablation, patients were monitored for 24 h, with an ECG Holter used for symptomatic cases.

This study enrolled five patients with classic paroxysmal nocturnal hemoglobinuria (cPNH) who underwent allogeneic hematopoietic stem cell transplantation in our hospital from 2019 to 2023. All five patients were male, with a median age of 26 (range: 26-46) years. The median time from diagnosis to allo-HSCT was 5.
