Coexistence of Interstitial Nephritis and the Cellular Variant of Focal Segmental Glomerulosclerosis Secondary to Anabolic Steroid Abuse.

Anabolic-androgenic steroids (AAS) have been widely used by young people to enhance performance and increase muscle mass. The use of AAS can affect the kidneys and lead to a myriad of presentations, ranging from mildly elevated serum creatinine and blood urea nitrogen to irreversible chronic kidney disease and focal segmental glomerulosclerosis (FSGS). To the best of our knowledge, the coexistence of interstitial nephritis and the cellular variant of FSGS [Immunoglobulin M (IgM)] secondary to AAS abuse has not been previously reported in the literature.

Osteoid Osteoma of the Proximal Humerus: A Case Report and Literature Review.

Osteoid osteoma is a common benign primary bone tumor, but it is very uncommon in the proximal humerus. This case report describes the clinical course and treatment of a patient with shoulder pain and osteoid osteoma of the proximal humerus and provides a review of the literature. A 22-year-old healthy male patient presented to our clinic with a 2-year history of constant throbbing right shoulder pain.

Coincidental light chain induced proximal tubulopathy with lupus nephritis: a case report and review of the literature.

Background: We report a case of light chain proximal tubulopathy associated with lupus nephritis in a patient known to have systemic lupus erythematosus. The kidney can be injured in several ways in any of these disorders. Light chain proximal tubulopathy is a rare form of renal tubular injury that may occur in and complicate plasma cell dyscrasia, characterized by cytoplasmic inclusions of the monoclonal light chain within proximal tubular cells.

Nicorandil prevents the nephrotoxic effect of cyclosporine-A in albino rats through modulation of HIF-1α/VEGF/eNOS signaling.

Despite that cyclosporine-A (CsA) is a widely used immunosuppressive drug, its nephrotoxic effect limits its long-term administration. Herein we tried to investigate its renal effect on endothelial dysfunction targeting the hypoxia-inducible factor (HIF-1α) / vascular endothelial growth factor (VEGF) / endothelial nitric oxide synthase (eNOS) pathway and the possible modulation by nicorandil. Eight groups of adult male Wistar rats were included: (1) control; (2) vehicle group (received oil); (3) glibenclamide 5 mg·kg·day administered orally; (4) nicorandil 10 mg·kg·day administered orally; (5) CsA 25 mg·kg·day administered orally; (6) combined administration of CsA and nicorandil; (7) glibenclamide was added to CsA; and (8) both CsA and nicorandil were combined with glibenclamide.

Vitamin D protection from rat diabetic nephropathy is partly mediated through Klotho expression and renin-angiotensin inhibition.

Objective: We hypothesised that vitamin D has a beneficial renal protective effect from diabetic nephropathy (DN).

Methods: Four rat groups were included: normal control (control), type 2 diabetes for eight weeks (DM), treated group with angiotensin receptor blocker losartan (DM + L), and vitamin D-treated group started from the onset of diabetes (DM + Vit D).

Results: In the both treated groups, we found a significant (p < .

A comparative study of different amniotic membrane orientations during extraocular muscle surgery in rabbits.

Purpose: To histopathologically compare the effect of different orientations of cryopreserved human amniotic membrane (AM) transplant during extraocular muscle surgery in rabbits.

Methods: Fifty-two albino rabbit eyes underwent 4-mm resection of the superior rectus. Eyes were randomly divided into four groups.
