Background: The adrenal gland is a frequent site of dissemination for certain types of tumors. Aggressive treatment remains controversial. The benefit of adrenalectomy has been observed, but the ultimate role remains to be elucidated.
Materials And Methods: We conducted a retrospective study analyzing the records of all patients with adrenal metastases submitted to adrenalectomy (open or laparoscopic) at our institution from 1981 to 2010. Baseline characteristics, operative outcomes, and survival were analyzed; predictive factors were also studied by multivariate analysis.
Results: A total of 65 patients were included with a median age of 60 years. Primary tumor sites were renal (35%), pulmonary (23%), melanoma (7%), colon (2%), liver (1%), and others. Mean metastasis size was 7 ± 4.2 cm with a mean interval to metastasis diagnosis of 39 months. Laparoscopic approach was done in 50% of cases. Postoperative morbidity was present in 9%, and 2 early deaths were observed. Median overall survival was 48 months and 45% at 5 years. Univariate and multivariate analyses showed better prognosis for renal metastases (p = 0.007 and 0.009) and those with size <5 cm (p = 0.011 and 0.031). Also in univariate analysis: synchronous (p = 0.02), symptomatic (p = 0.04), and laparoscopically operated (p = 0.033) metastasis showed higher survival rates. Metastasis from pulmonary tumors had the worst prognosis.
Conclusions: Adrenalectomy should be considered in patients with adrenal metastasis from renal carcinoma, as well as in those with small secondary lesions from other type of tumor with a controlled primary disease. The clear benefit of adrenalectomy remains to be documented in pulmonary carcinoma metastasis.

Aging is a complex biological process that involves the gradual decline of cellular, tissue, and organ functions. In kidney, aging manifests as tubular atrophy, glomerulosclerosis, and progressive renal function decline. The critical role of senescence-associated macrophage in diseases, particularly kidney diseases, is increasingly recognized.

Case Summary: A 13-year-old male castrated domestic shorthair cat presented with a 2-month history of progressive lameness, poor appetite and constipation. Physical examination revealed palpable lesions in muscles of several extremities. Ultrasound examination confirmed the presence of round lesions with a hypo- or anechoic centre within the muscles.

The kidney proximal tubule reabsorbs and degrades filtered plasma proteins to reclaim valuable nutrients and maintain body homeostasis. Defects in this process result in proteinuria, one of the most frequently used biomarkers of kidney disease. Filtered proteins enter proximal tubules via receptor-mediated endocytosis and are processed within a highly developed apical endo-lysosomal system (ELS).

Background: Liver fibrosis is caused by chronic toxic or cholestatic liver injury. Fibrosis results from the recruitment of myeloid cells into the injured liver, the release of inflammatory and fibrogenic cytokines, and the activation of myofibroblasts, which secrete extracellular matrix, mostly collagen type I. Hepatic myofibroblasts originate from liver-resident mesenchymal cells, including HSCs and bone marrow-derived CD45+ collagen type I+ expressing fibrocytes.

Context: TIO, a paraneoplastic disorder characterised by renal phosphate wasting, is cured by surgical removal of the culprit tumour. Despite correct localization, some remain refractory to intervention, resulting in substantial long-term medical complications.
Aim: We aim to identify risk factors associated with a refractory outcome.
