January 2025

From the Division of Anaesthesiology, Department of Anaesthesiology, Pharmacology, Intensive Care and Emergency Medicine, University Hospitals of Geneva, Geneva, Switzerland (ADSR, MB, RS, GA, ES), Department of Anaesthesia, Northern Lisbon University Hospital Centre, Lisbon, Portugal (ADSR), University Clinic of Anesthesiology and Reanimation, Faculty of Medicine, University of Lisbon, Portugal (ADSR), Division of Clinical Pharmacology and Toxicology, Department of Anaesthesiology, Pharmacology and Intensive Care, University Hospitals of Geneva, Geneva, Switzerland (AN).

Resistance to the effects of rocuronium and other neuromuscular blocking agents (NMBA) has been previously reported, including delayed onset of relaxation, rapid recovery and incomplete paralysis under recommended doses. These conditions have been associated with denervation injury, burns, immobilisation, infections, metabolic disorders, and drug interactions. In this report, we describe the case of a young male without any known pre-disposing factor for NMBA resistance, who failed to attain muscle relaxation with non-depolarising NMBA despite high doses of rocuronium and atracurium during two surgeries for colorectal cancer, several months apart.

Histomorphometric parameters of iliac bone in healthy individuals: Systematic review and meta-analysis.

Bone

January 2025

Nephrology Department, Laboratorio de Fisiopatologia Renal 16 (LIM 16), Hospital das Clinicas, Faculdade de Medicina da Universidade de São Paulo, São Paulo, SP, Brazil.

Despite its invasive character, bone biopsy followed by histomorphometry remains the gold standard for diagnosing and classifying many metabolic bone diseases. However, the interpretation of histomorphometric parameters requires comparison with average values obtained from a proper control group, which are only available for some populations, and reference standards still need to be published. Therefore, our objective was to estimate average values for bone histomorphometric parameters overall, by age, gender, and race (White and Black) categories of healthy adult individuals, based on a systematic review and meta-analysis of clinical studies.
