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.

Impact of hepatitis virus infection on arterial calcification among incident hemodialysis patients.

Background: The impact of hepatitis virus infection on arterial calcification (AC) was not studied.

Objective: To study the prevalence, severity and distribution of AC in incident hemodialysis patients with hepatitis B and C viral infection.

Cases And Methods: 172 stage 5 CKD adults (98 male and 74 female) were included; 58 of them were seronegative for both hepatitis B and C (SN group), 48 were positive for hepatitis B virus infection (HBV group) and 66 were hepatitis C virus positive (HCV group).

Spectrum of glomerulonephritis in Egyptian patients with rheumatoid arthritis: A University Hospital experience.

Rheumatoid arthritis (RA) is accompanied by a variety of nephropathies. It is often difficult to distinguish between disease-associated and drug-associated renal diseases. Three hundred and seventy-six RA patients with renal involvement were included in our study; they were subjected to full history and clinical examination, kidney function, 24-h urinary protein, and kidney biopsy.

Intraoperative Arterial Biopsy in Incident Hemodialysis Patients: Differences Observed.

Introduction: Arterial calcification (AC) is a common complication in chronic kidney disease (CKD) patients that starts to develop before these patients need renal replacement therapy. In these patients, calcification can involve tunica intima or tunica media. This study has looked for the prevalence, severity, and distribution of arterial wall calcification in incident hemodialysis patients through intraoperative arterial biopsy obtained during creation of arteriovenous vascular access for hemodialysis.

Incidence and Characteristics of de novo Renal Cryoglobulinemia After Direct-Acting Antivirals Treatment in an Egyptian Hepatitis C Cohort.

Introduction: The side effects profile of the new direct--acting antivirals for the treatment of hepatitis C virus (HCV) is not fully elucidated.

Objective: In this cross-sectional study, we aim to describe the incidence and characteristics of a novel observation of de novo renal cryoglobulinemic glomerulonephritis after successful treatment with DAA.

Methodology: A total of 12,985 Hepatitis C Patients (genotype IV) received the new DAA.

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.

Chronic renal allograft dysfunction in Egyptian population: Histopathological and immunohistochemical study.

The chronic dysfunction stands as the most common cause of renal allograft loss. During the nineties of the past century, this condition was referred to as chronic allograft nephropathy (CAN). Since 2005, CAN has been assigned by the eighth Banff schema to four main categories via histopathological and immunohistochemical findings including chronic antibodymediated rejection (CAMR), chronic T-cell-mediated rejection (CTMR), chronic cyclosporine toxicity (CNITOX), and "interstitial fibrosis (IF)/tubular atrophy; not otherwise specified (NOS)" to eliminate the term CAN.

Impact of intravitreal triamcinolone acetonide versus intravitreal bevacizumab on retrobulbar hemodynamic in patients with diabetic macular edema.

Purpose: To evaluate and compare retrobulbar hemodynamic changes measured with color Doppler imaging (CDI) in diabetic patients receiving intravitreal triamcinolone acetonide (IVTA) versus bevacizumab.

Methods: Patients with diffuse diabetic macular edema were assessed prospectively by CDI following intravitreal injection of triamcinolone acetonide (group I, 12 eyes) versus bevacizumab (group II, 14 eyes). CDI was used to measure the peak systolic velocity (PSV), end diastolic velocity (EDV) and the resistive index (RI) of the central retinal artery (CRA), ophthalmic artery (OA) and posterior ciliary arteries (PCA) one day preoperatively and one week postoperatively.
