Background: This study was undertaken to investigate the growth rate and clinical outcome of patients with a small renal mass (SRM) after delayed surgery.
Methods: We reviewed the clinical records of 34 patients with SRMs ≤ 4 cm at diagnosis, who underwent delayed surgical intervention during surveillance from January 2000 to December 2011. Radiographic evaluations using computed tomography (CT) scan and magnetic resonance imaging (MRI) were performed at least every 6 months, and the tumor size was determined at least twice.
Results: The mean follow-up time was 26.6 ± 18.6 months and mean tumor doubling time was 23.4 ± 16.0 months. Histopathological analysis revealed that 32 of the 34 patients were malignant in pT1aN0M0. Only one patient showed tumor recurrence, who subsequently died due to tumor progression.
Conclusion: The growth rate of the small renal mass was slow in the majority of our patients. Delayed intervention does not have a detrimental effect on cancer-specific outcomes.

The Role of Intravenous Selexipag in Managing PAH and Bridging Gaps in Oral Treatment: A Narrative Review.

Pulmonary arterial hypertension (PAH) is a rare and potentially fatal condition characterized by progressive increases in blood pressure in the arteries of the lungs. Oral selexipag, approved by the Food and Drug Administration (FDA) in 2015 for the treatment of PAH, targets prostacyclin receptors on pulmonary arterial vascular smooth muscle and endothelial cells to improve blood flow through the lungs and reduce pulmonary vascular resistance. Oral selexipag is effective, but may be discontinued due to factors like side effects, emergency conditions, or inability to take oral medication, potentially leading to severe adverse events, such as rebound pulmonary hypertension and right heart failure.

Dipeptidase 1 (DPEP1), initially identified as a renal membrane enzyme in mature human kidneys, plays a pivotal role in various cellular processes. It facilitates the exchange of materials and signal transduction across cell membranes, contributing significantly to dipeptide hydrolysis, glucose and lipid metabolism, immune inflammation, and ferroptosis, among other cellular functions. Extensive research has delineated the complex role of DPEP1 in oncogenesis and tumor progression, with its influence being context dependent.

A 50-year-old patient with a prior history of chronic smoking presented to the emergency department with diffuse abdominal pain, primarily localized to the right hypochondrium and epigastric region, along with nausea, but without fever, vomiting, or urinary symptoms. Laboratory tests were largely unremarkable except for isolated hematuria and a mildly elevated CRP. Given the atypical clinical presentation, a 3-phase abdominal CT scan (without contrast, portal, and delayed phases) was conducted, revealing a horseshoe kidney with an obstructing 4 mm stone at the right ureteral meatus.

Background: Metastasis of non-gastrointestinal (non-GI) cancers to the upper GI tract is a rare occurrence, with limited cases reported in the literature. Recognising this type of metastasis is crucial, as it presents unique diagnostic and therapeutic challenges. This case series adds to the literature by discussing seven rare cases of non-GI cancer metastasising to the upper GI tract, emphasising the complications and clinical manifestations.
