Impact of Using Blood Warmer During Continuous Kidney Replacement Therapy in Patients With Acute Kidney Injury.

PURPOSE: We investigated the impact of blood warmer use on hypotensive episodes in patients with acute kidney injury (AKI) receiving continuous kidney replacement therapy (CKRT). MATERIALS AND METHODS: We included patients with AKI undergoing CKRT between January 1, 2012, and January 1, 2021, at a tertiary academic hospital. Hypotensive episodes were defined as mean arterial pressure (MAP) <60 mm Hg or a decrease in MAP by ≥10 mm Hg, systolic blood pressure (SBP) < 90 mm Hg or a decrease in SBP by ≥20 mm Hg, or increased vasopressor requirement. These were analyzed by Poisson regression with repeated-measures analysis of variance using generalized estimation equation. RESULTS: There were 669 patients with AKI that required CKRT. Use of blood warmer on first day of CKRT was in 324 (48%) patients. Incidence rate ratio of hypotensive episodes during the first 24-h of CKRT in patients where a blood warmer was used was 1.06 (95% confidence interval [CI]: 0.98-1.13) compared to those where blood warmer was not used. This did not change in adjusted model. Overall, the within-subject effect of temperature on hypotensive episodes showed that higher temperature was associated with fewer episodes (0.94, 95% CI: 0.9-0.99 per 10 degrees increase, P = .007). CONCLUSION: Blood rewarming was not associated with hypotensive episodes during CKRT.

Impending Cardiac Tamponade as the Initial Manifestation of BCR-ABL Positive Chronic Myeloid Leukemia.

Leukemia involves all organs and tissues of the body. Leukemic infiltration of the pericardium has been documented frequently at post-mortem examinations. Clinically, however, pericardial effusion with cardiac tamponade is rare, and only isolated case reports have been described. In all the reported cases, therapeutic pericardiocentesis was required for the relief of cardiac tamponade with the risk of bleeding since these patients often had deranged hemostasis. We are reporting a rare case of hemorrhagic pericardial effusion in chronic myeloid leukemia before starting the tyrosine kinase inhibitors. The patient required therapeutic pericardiocentesis and hydroxyurea treatment.

A Rare Case of Subacute Painful Thyroiditis Causing Thyroid Storm and a Successful Trial of Propylthiouracil.

Thyroid storm is a rare, life-threatening condition characterized by severe or exaggerated clinical manifestations of thyrotoxicosis, commonly occurring in patients with longstanding, untreated hyperthyroidism such as Graves' disease and toxic nodular goiter. Subacute painful thyroiditis, also known as de Quervain thyroiditis, is a self-limited inflammatory disease of the thyroid gland that is characterized by neck pain, a tender diffuse thyroid goiter, elevated inflammatory markers, and a predictable course of thyroid function evolution. Rarely, it can cause thyroid storm. Herein, we report a rare case of a 25-year-old woman who was admitted for sepsis and acute painful thyroiditis who then developed thyroid storm. The patient was treated in the intensive care unit (ICU) and responded very well to steroids, propranolol, a seven-day trial of propylthiouracil, and ultimately achieved a euthyroid state on discharge.

Non-Ketotic Hyperglycemia Causing a Transient Unilateral Homonymous Hemianopia: A Manifestation of Occipital Lobe Seizure.

Focal seizures related to non-ketotic hyperglycemia (NKH) are rare in clinical practice. Plasma glucose levels are usually above 16.6 mmol/L and with normal or slightly elevated serum osmolality. The occurrence of focal seizures may be augmented by the absence of ketoacidosis. Electroencephalogram (EEG) during seizures usually confirms the diagnosis, however, the absence of epileptiform discharges does not rule out seizures. A non-ketotic hyperglycemia-associated occipital lobe seizure can manifest itself as color flashes, blurry vision with periodic confusion, and usually resolves with insulin treatment and rehydration. We are reporting a 65-year-old male patient who presented with intermittent confusion and left-sided visual disturbances, found to have a blood glucose of 33.7 mmol/L with a normal anion gap of 10 and calculated serum osmolality of 303 mOsm/L. The patient's visual disturbances responded very well to rehydration and insulin treatment.

A Rare Case of Immune-Mediated Primary Adrenal Insufficiency With Cytotoxic T-Lymphocyte Antigen-4 Inhibitor Ipilimumab in Metastatic Melanoma of Lung and Neck of Unknown Primary.

Immunotherapy with checkpoint inhibitors such as ipilimumab, a cytotoxic T-lymphocyte antigen-4 (CTLA-4) inhibitor, and nivolumab, a programmed death-1 (PD-1) inhibitor, has significantly improved the survival of patients with metastatic melanoma. The immune-related endocrinopathies of these treatments have been well documented, such as hypothyroidism, hyperthyroidism, primary adrenal insufficiency (PAI), insulin-dependent diabetes, and hypophysitis. We report the onset of PAI in a patient with metastatic melanoma to the lung and neck of unknown primary origin who was treated with ipilimumab. The patient's symptoms resolved with steroid replacement. After the completion of 16 cycles of another checkpoint inhibitor, nivolumab, full remission was achieved.
