We present a rare case of renal cell carcinoma (RCC) with a metastatic, mainly osteoblastic lesion of the skull and spread to the lymph nodes. Renal tumors are often associated with bone metastases; these are most often of the osteolytic type, while osteoblastic metastases are extremely rare. In the case presented here, the primary metastasis was a large osteoblastic lesion of the skull that spread to the lymph nodes. The patient has undergone treatment for 20 months with interleukin-2: 3 million IU/day (subcutaneous) for six consecutive days once every four weeks, ie a total weekly dose of 18 million IU.

Immunoglobulin A nephropathy (IgAN) is the most common primary glomerulonephritis worldwide with heterogeneous histopathological phenotypes. Although IgAN with membranoproliferative glomerulonephritis (MPGN)-like features has been reported in children and adults, treatment strategies for this rare IgAN subtype have not been established. Here, we present the case of a 56-year-old man with no history of kidney disease who initially presented with nephrotic syndrome.

Rationale & Objective: Monoallelic predicted Loss-of-Function (pLoF) variants in IFT140 have recently been associated with an autosomal dominant polycystic kidney disease (ADPKD)-like phenotype. This study sought to enhance the characterization of this phenotype.
Study Design: Case series.

Introduction: Tacrolimus-induced thrombotic microangiopathy (TMA) causing acute kidney injury (AKI) without systemic features is a rare entity, particularly after non-renal solid organ transplantation.
Case Report: We describe the case of a patient with AKI after combined heart and lung transplantation. Renal biopsy revealed acute thrombotic microangiopathy which ultimately prompted initiation of eculizumab, a monoclonal antibody targeted against complement C5, with subsequent recovery in renal function.

The subspecialty of neurocritical care has grown significantly over the past 40 years along with advancements in the medical and surgical management of neurological emergencies. The modern neuroscience intensive care unit (neuro-ICU) is grounded in close collaboration between neurointensivists and neurosurgeons in the management of patients with such conditions as ischemic stroke, aneurysmal subarachnoid hemorrhage, intracerebral hemorrhage, subdural hematomas, and traumatic brain injury. Neuro-ICUs are also capable of specialized monitoring such as serial neurological examinations by trained neuro-ICU nurses; invasive monitoring of intracranial pressure, cerebral oxygenation, and cerebral hemodynamics; cerebral microdialysis; and noninvasive monitoring, including the use of pupillometry, ultrasound monitoring of optic nerve sheath diameters, transcranial Doppler ultrasonography, near-infrared spectroscopy, and continuous electroencephalography.

BACKGROUND Toluene poisoning can occur as a result of occupational exposure in industries such as painting, as well as through misuse, leading to complications such as neurological symptoms due to the accumulation of the metabolic byproduct of hippuric acid and metabolic acidosis. However, the exact mechanisms remain unclear. Hippuric acid is not removed by dialysis, so urinary excretion plays a central role.
