Integrative Volume Status Assessment.

Volume status assessment is a critical but challenging clinical skill and is especially important for the management of patients in the emergency department, intensive care unit, and dialysis unit where accurate intravascular assessment is necessary to guide appropriate fluid management. Assessment of volume status is subjective and can vary from provider to provider, posing clinical dilemmas. Traditional non-invasive methods of volume assessment include assessment of skin turgor, axillary sweat, peripheral edema, pulmonary crackles, orthostatic vital signs, and jugular venous distension.

Lung Ultrasound to Diagnose Pulmonary Congestion Among Patients on Hemodialysis: Comparison of Full Versus Abbreviated Scanning Protocols.

Rationale & Objective: Pulmonary congestion contributes to morbidity and mortality in patients with kidney failure on hemodialysis, but physical assessment is an insensitive approach to its detection. Lung ultrasound is useful for assessing the presence and severity of pulmonary congestion, but the most widely validated 28-zone study is cumbersome. We sought to compare abbreviated 4-, 6-, and 8-zone studies to 28-zone studies.

Persistent Interferon Production by Double Negative T Cells and Collapsing Focal Segmental Glomerulosclerosis.

Collapsing glomerulopathy has multiple associations, including viral infections, medications like bisphosphonates and interferon, autoimmune diseases, and genetic predisposition. We report a case of collapsing focal segmental glomerulosclerosis associated with persistently high levels of interferon gamma produced by T-cell receptor αβ (+), CD4- CD8- (double negative) T lymphocytes that progressed despite treatment and improvement of other cytokine levels. Double negative T cells are elevated and activated in autoimmune lymphoproliferative syndrome (ALPS).

Contrast Media-Different Types of Contrast Media, Their History, Chemical Properties, and Relative Nephrotoxicity.

History of contrast dates back to the 1890s, with the invention of the radiograph. Nephrotoxicity has been a main limitation in ideal contrast media (CM). High-osmolar contrast media no longer are in clinical use due to overwhelming evidence supporting greater nephrotoxicity with these CM compared with current CM.

A unique case of nephrogenic systemic fibrosis from gadolinium exposure in a patient with normal eGFR.

A 57-year-old woman presented with swelling and thickening of the skin of the lower extremities. Three months prior to presentation, patient had MRI with gadolinium as part of an evaluation for suspected pancreatic malignancy. Creatinine levels at the time of gadolinium exposure were 0.

Apolipoprotein C-II Deposition Amyloidosis: A Potential Misdiagnosis as Light Chain Amyloidosis.

Hereditary amyloidoses are rare and pose a diagnostic challenge. We report a case of hereditary amyloidosis associated with apolipoprotein C-II deposition in a 61-year-old female presenting with renal failure and nephrotic syndrome misdiagnosed as light chain amyloidosis. Renal biopsy was consistent with amyloidosis on microscopy; however, immunofluorescence was inconclusive for the type of amyloid protein.

A case of hypermucoviscous Klebsiella pneumoniae liver abscess syndrome in an Iraqi male.

A 53-year-old man presented with fevers, productive cough and decreased appetite. He emigrated from Iraq 4 years ago. Chest x-ray revealed a left lung consolidation.
