In patients with hematologic malignancies, acute kidney injury (AKI) is the most common kidney complication requiring nephrologist consultation. Although the causes of AKI are multifactorial, primary tumor infiltration is rare in patients with acute myeloblastic leukemia (AML). This makes it challenging to determine the cause of AKI and the optimal chemotherapy regimen for AML. We describe two cases of AML (French-American-British classification: M2, M4) in patients with AKI requiring hemodialysis. We successfully identified the cause of AKI as primary leukemic infiltration and started induction chemotherapy in the setting of hemodialysis. This treatment significantly improved renal function and resulted in AML remission. In this report, we describe several clinical characteristics of AKI due to primary tumor infiltration. In addition, we emphasize the importance of onconephrology, a new subspecialty concerned with the complex relationship between the kidneys and cancer.

Malignant peripheral nerve sheath tumors (MPNSTs) are aggressive sarcomas and the primary cause of mortality in patients with neurofibromatosis type 1 (NF1). These malignancies develop within preexisting benign lesions called plexiform neurofibromas (PNs). PNs are solely driven by biallelic loss eliciting RAS pathway activation, and they respond favorably to MEK inhibitor therapy.

Background: Glioblastoma is characterized by neovascularization and diffuse infiltration into the adjacent tissue. T2*-based dynamic susceptibility contrast (DSC) MR perfusion images provide useful measurements of the biomarkers associated with tumor perfusion. This study aimed to distinguish infiltrating tumors from vasogenic edema in glioblastomas using DSC-MR perfusion images.

Background: The current management of psoriasis does not differentiate between young and old patients in selecting the safest and/or most effective biologic.
Objectives: To explore the effect of age at treatment initiation in response to biologics in patients with moderate-to-severe psoriasis in the UK and Eire.
Methods: Data from patients registering to the British Association of Dermatologists Biologics and Immunomodulators Register (BADBIR) from 2007-2024 on first course of Tumour Necrosis Factor (TNF), interleukin (IL) 12/13, IL-17 and IL-23 inhibitors (i) with at least 6 months' follow-up were included.

Background: This paper presents the authors' team's research on a craniofacial surgical robot developed in China. Initiated in 2011 with government funding, the craniofacial surgical robot project was officially launched in Shanghai, developed jointly by the Ninth People's Hospital affiliated with Shanghai Jiao Tong University School of Medicine and the Shanghai Jiao Tong University medical-engineering team. Currently, based on multiple rounds of model surgeries, animal experiments, and clinical trials, our team is applying for approval as a Class III medical device from the National Medical Products Administration (NMPA).

Rationale: The occurrence of refractory small cell lung cancer (rSCLC) with pancreatic metastasis is a relatively rare clinical condition, which is typically accompanied by a poor prognosis and rapid disease progression.
Patient Concerns: A 65-year-old male farmer from China was diagnosed with limited-stage small cell lung cancer (SCLC) 8 months ago. Following 6 cycles of EP chemotherapy, the patient's tumor response showed partial relief.
