Unmasking Multiple Myeloma: The Importance of Suspecting Malignancy in Atypical Chronic Pain Mimicking Degenerative Conditions-A Case Report.

Heightened clinical vigilance for multiple myeloma is essential in patients presenting with atypical chronic pain progression. Symptoms may overlap with degenerative musculoskeletal conditions, frequently leading to misdiagnosis. This underscores the necessity of a thorough evaluation when symptoms are refractory to conventional therapies, in order to facilitate timely diagnosis and effective management of malignancy.

Ventilator Failure Following Cardiopulmonary Bypass: A Case Report.

We present 3 cardiothoracic surgery cases during which the Drager Perseus A500 anesthesia machine and the iNOmax Delivery System were used concurrently, resulting in ventilator failures while attempting to separate from cardiopulmonary bypass (CPB). The failure was found to be caused by the iNOmax Delivery System sampling line, where negative pressure on the Perseus A500 breathing circuit precipitated a ventilator failure when the machine was brought out of "standby mode." To our knowledge, there is no discussion of this interaction in the literature, and we find this to be an important issue for patient safety during cardiothoracic surgery.
