Peripheral neuropathy (PN) has rarely been described as a complication of erythropoietic protoporphyria (EPP). We describe three episodes of PN and the electrophysiologic findings in two patients with EPP. PN is seen in patients with EPP and hepatic failure and raised free erythrocyte protoporphyrin or serum protoporphyrin levels and is identical to that seen in acute intermittent porphyria. Recognition is important because of the good eventual prognosis.

Real-world assessment of the patient profile, clinical characteristics, treatment patterns, and outcomes associated with erythropoietic and X-linked protoporphyria.

Article Synopsis
- Erythropoietic protoporphyria (EPP) and X-linked protoporphyria (XLP) are rare genetic disorders that lack comprehensive management data, prompting a study of their characteristics and treatment in real-world U.S. settings.
- The study reviewed medical records of 299 EPP and 91 XLP patients, revealing a mean diagnosis delay of 2.9 years and highlighting common pre-diagnostic tests and lifestyle recommendations.
- Findings indicated a significant number of healthcare visits post-diagnosis and identified unmet needs, such as the need for quicker diagnoses, effective symptom relief, and better prevention of phototoxic reactions.
Surgery for pleural mesothelioma in multimodality setting: comparison between surgical techniques in a high-volume centre.
Eur J Cardiothorac Surg
November 2024
Thoracic Surgery Unit, Department of Cardiac, Thoracic, Vascular Sciences and Public Health, University of Padova, Padova, Italy.
Objectives: Pleural mesothelioma (PM) is an aggressive disease linked to asbestos exposure, presenting significant treatment challenges. The recommended approach is multimodal treatment, even if the concept of resectable PM and the superiority of one surgical technique over the other [(extended) pleurectomy decortication [(E)PD] vs extra-pleural pneumonectomy (EPP)] are matter of debates. The aim of this study is to compare the 2 techniques in terms of short- and long-term outcomes at a high-volume centre.

J Thorac Dis
October 2024
Department of Surgery, Maxima Medical Center, Eindhoven, The Netherlands.
Background: Despite the benefits of video-assisted thoracoscopic surgery (VATS), postoperative acute pain and nerve injury are still present and contribute to early persistent and chronic pain. The purpose of this study is to describe the incidence of early persistent pain (EPP) after VATS, which remains unexplored, to enhance patient care and promote awareness among clinicians regarding this clinical condition.
Methods: A single-center prospective cohort study that included consecutive patients undergoing VATS between January 2021 and March 2023.
RAS-mutant leukaemia stem cells drive clinical resistance to venetoclax.
Nature
December 2024
Department of Oncological Sciences, Icahn School of Medicine at Mount Sinai, New York, NY, USA.
Article Synopsis
- * The study reveals that RAS mutations transform specific blood cell progenitors (granulocyte-monocyte progenitors) that have already acquired other mutations, suggesting advanced leukemia can arise from different cell types than initial clones.
- * RAS-mutant leukemia stem cells show resistance to the treatment drug venetoclax due to changes in gene expression, leading to worse treatment responses and relapses characterized by monocytic features, highlighting the impact of genetic drivers on therapy effectiveness.
Introduction: depression is more frequent among people with obesity (PwO) compared to the general population. Depression seems to improve after bariatric surgery (BS) at short term, but data are inconclusive at long term. Besides, it is not known whether depressive symptoms among PwO are similar to those people with a major depression without obesity.
