Detection and Quantification of Circulating Tumor Cells in Salvaged Blood in Surgical Osteosarcoma Patients: A Pilot Study from a Tertiary Medical Center

Osteosarcoma(OS)is a common primary malignant bone tumor that most commonly affects adolescents and children under 20.According to previous research,OS is distinguished by high-grade malignancy,rapid progression,distant metastasis,and a low long-term survival rate.Because of accurate diagnosis,pathological classification of biopsy,multiagent perioperative chemotherapy,and limb-salvage surgery,over-all survival rate of OS patients has significantly enhanced in recent years.

Anesthetics management of a renal angiomyolipoma using pulse pressure variation and non-invasive cardiac output monitoring: A case report

BACKGROUND Hypovolemic shock can lead to life-threatening organ dysfunction,and adequate fluid administration is a fundamental therapy.Traditionally,parameters such as vital signs,central venous pressure,and urine output have been used to estimate intravascular volume.Recently,pulse pressure variation(PPV)and non-invasive cardiac monitoring devices have been introduced.In this case report,we introduce a patient with massive active bleeding from giant renal angiomyolipoma(AML).During emergent nephrectomy,we used non-invasive cardiac monitoring with CSN-1901(Nihon Kohden,Tokyo,Japan)and PPV to evaluate the patient's intravascular volume status to achieve optimal fluid management.CASE SUMMARY A 30-year-old male patient with giant AML with active bleeding was referred to the emergency room complaining of severe abdominal pain and spontaneous abdominal distension.AML was diagnosed by computed tomography,and emergent nephrectomy was scheduled.Massive bleeding was expected so we decided to use non-invasive cardiac monitoring and PPV to assist fluid therapy because they are relatively easy and fast compared to invasive cardiac monitoring.During the surgery,6000 mL of estimated blood loss occurred.Along with the patient's vital signs and laboratory results,we monitored cardiac output,cardiac output,stroke volume,stroke volume index with a non-invasive cardiac monitoring device,and PPV using an intra-arterial catheter to evaluate intravascular volume status of the patient to compensate for massive bleeding.CONCLUSION In addition to traditional parameters,non-invasive cardiac monitoring and PPV are useful methods to evaluate patient's intravascular volume status and provideguidance for intraoperative management of hypovolemic shock patients.

Overlap of diabetic ketoacidosis and hyperosmolar hyperglycemic state

Diabetic ketoacidosis(DKA)and hyperosmolar hyperglycemia state(HHS)are two life-threatening metabolic complications of diabetes that significantly increase mortality and morbidity.Despite major advances,reaching a uniform consensus regarding the diagnostic criteria and treatment of both conditions has been challenging.A significant overlap between these two extremes of the hyperglycemic crisis spectrum poses an additional hurdle.It has well been noted that a complete biochemical and clinical patient evaluation with timely diagnosis and treatment is vital for symptom resolution.Worldwide,there is a lack of large-scale studies that help define how hyperglycemic crises should be managed.This article will provide a comprehensive review of the pathophysiology,diagnosis,and management of DKA-HHS overlap.
