Transversus abdominis plane (TAP) block for postoperative pain management after ventral hernia repair: an updated systematic review and meta-analysis.

Background: Postoperative pain remains a common concern following ventral hernia repair (VHR), especially for open procedures. We aim to assess the effectiveness of the Transversus Abdominis Plane (TAP) block for the management of postoperative pain following VHR.

Methods: Cochrane, EMBASE, and PubMED, MEDLINE, and Web of Science were systematically searched for studies comprising adults undergoing VHR with preoperative TAP block, compared to placebo and epidural analgesia.

Dysphagia, nutritional status, and quality of life in patients with head and neck cancer undergoing radiotherapy alone or combined with chemotherapy: an observational study.

Introduction: Radiotherapy (RT) is the most common nonsurgical treatment for head and neck cancer (HNC) and may or may not be combined with chemotherapy (CT). Dysphagia, characterized by impaired swallowing function, is one of the most common side effects of RT, occurring during and after RT, and may persist long after treatment.

Objective: To compare the evolution of dysphagia, nutritional status, and quality of life (QoL) in the periods immediately before and after RT for HNC in individuals who received only RT or combined RT/CT.

Azacitidine-induced bullous pemphigoid-like localized toxic reaction.

Azacitidine is a hypomethylating agent recommended for the treatment of patients with high-risk myelodysplastic syndromes. Here, we report the case of a patient with myelodysplastic syndrome who was not eligible for allogeneic stem cell transplantation (allo-SCT) and presented with a rare and previously unreported cutaneous side effect after the use of subcutaneous azacitidine. We propose that changing the route of azacitidine administration from subcutaneous to intravenous could potentially decrease the occurrence of bullous pemphigoid-like localized toxic reactions in some patients.
