Kidney biopsy in the Military Hospital of Morocco: Complications and histopathological findings.

Epidemiological studies on renal biopsies are necessary to establish the pattern and trends of renal diseases in a particular geographic area. In this retrospective study, we reviewed the medical records, histopathology findings and complications of renal biopsy in a region of Morocco. We studied a total of 130 native kidney biopsies taken between January 2008 and January 2012.

Lupus nephritis emerging during remission of minimal change disease.

Introduction: Rare cases of association between lupus nephritis (LN) and minimal changes nephrotic syndrome (MCNS) were described. Some authors suggest that this association, taking into account the low prevalence of both diseases, may not be a simple coincidence. Several pathophysiological hypotheses have been proposed to explain this association, including a potential central role of T lymphocytes.

Quantification of hemodialysis dose: what Kt/V to choose?

Background: Quantification of hemodialysis became more accurate and easier after the advent of ionic dialysance and the use of methods for estimating urea distribution volume (V). The aim of this study was to compare different methods of hemodialysis dose assessment: Kt/VDau (Daugirdas 2nd generation), Kt/VOCM (Kt by OCM (Online Clearance Monitor) and V by Watson), and Kt/VBCM 
(Kt by OCM and V by bio-impedance); and to assess the dialysis adequacy, defined by a Kt/V>1.4.

Acute tubulo-interstitial nephritis with positive anti-neutrophil cytoplasmic antibodies.

Introduction: Anti-neutrophil cytoplasmic antibody (ANCA) associated vasculitis involving the kidney usually comprises pauci-immune, necrotizing glomerulonephritis with crescents. Mononuclear tubulo-interstitial infiltrates are common in ANCA associated vasculitis, but these have usually been described in conjunction with glomerulitis. Acute tubulo-interstitial nephritis (ATIN) is a common cause of acute kidney injury that is most frequently induced by drugs or infections.

Parameters to assess nutritional status in a Moroccan hemodialysis cohort.

Introduction: Malnutrition is common in maintenance hemodialysis (HD) and is associated with increased mortality and morbidity in affected patients. The aim of this study was to determine the prevalence of malnutrition and correlate the methods of nutritional assessment.

Methods: We evaluated the nutritional status of 40 prevalent HD patients by subjective global assessment (SGA) score, anthropometrics [body mass index (BMI), arm circumference (AC), triceps skin-fold thicknesses (TSF), arm muscle circumference (AMC)], biochemical tests [normalized protein equivalent to total nitrogen appearance (nPNA), and pre-dialysis serum albumin and serum prealbumin levels] and bio-electrical impedance (BEI) analysis to estimate body composition [lean tissue index (LTI) and fat tissue index (FTI)].

Finger movement at birth in brachial plexus birth palsy.

Aim: To investigate whether the finger movement at birth is a better predictor of the brachial plexus birth injury.

Methods: We conducted a retrospective study reviewing pre-surgical records of 87 patients with residual obstetric brachial plexus palsy in study 1. Posterior subluxation of the humeral head (PHHA), and glenoid retroversion were measured from computed tomography or Magnetic resonance imaging, and correlated with the finger movement at birth.

[Predilution online hemodiafiltration: which dose of anticoagulation?].

Introduction: Patients in end stage renal disease on hemodialysis are in higher risk of bleeding related to the anticoagulation used during a session, so only the lowest effective dose of anticoagulation must be used. The aim of this study was to evaluate the efficacy of predilution in hemodiafiltration with reduced dose of anticoagulation compared to hemodialysis in preventing coagulation of circuits.

Patients And Methods: This study was conducted in stable hemodialysis patients without high bleeding risk.

Applying sodium profile with or without ultrafiltration profile failed to show beneficial effects on the incidence of intradialytic hypotension in susceptible hemodilaysis patients.

Introduction: Intra-dialytic hypotension (IDH) is a common complication during hemodialysis (HD) treatment. Previous studies have reported that modulating dialysate sodium concentration combined or not with modulation of ultrafiltration (UF) rate may reduce the incidence of IDH. The aim of the present study was to evaluate the effect of sodium and UF profiles on the occurrence of intra-dialytic complications and dialysis quality.

Infective endocarditis in chronic hemodialysis patients: experience from Morocco.

Since the 1960s, regular hemodialysis (HD) was recognized as a risk factor for the development of infective endocarditis (IE), particularly at vascular access sites. The present report describes our experience at the Etat Major General Agadir, Morocco, of taking care of IE in patients on regular dialysis. A retrospective analysis was made of five cases of IE in patients receiving regular HD having arteriovenous fistula as vascular access.

[Clinical case of acute renal failure revealing an autoimmune hypothyroidism].

Although the clinic picture is often indicative of muscle manifestations in patients with hypothyroidism, signs and symptoms of this condition are variable from simple elevation of serum muscle enzymes with myalgia, muscle weakness, cramps to rhabdomyolysis with acute renal failure which remains a rare event. Thyroid hormones affect the function of almost every body organ, and thyroid dysfunction produces a wide range of metabolic disturbances. Hypothyroidism is associated with significant effects on the kidney which the pathophysiology seems to be multifactorial, but the exact mechanisms remain poorly understood.

[The nutcracker syndrome].

The nutcracker syndrome refers to compression of the left renal vein between the aorta and the superior mesenteric artery. After a review of the literature, the authors emphasize the uncommon incidence of this pathology, and the interest of imaging in the survey of this affection.

[Posterior-reversible encephalopathy in hemodialysis].

Posterior-reversible encephalopathy syndrome (PRES) is a recently clinicoradiologic entity caused by numerous medical conditions and characterized by acute-neurologic disorders, such as headaches, confusion, seizures associated with arterial hypertension. MRI characteristics are typical. The rapid diagnosis is of capital importance due to a potential reversibility.

How do calcimimetics fit into the management of parathyroid hormone, calcium, and phosphate disturbances in dialysis patients?

As suggested by its American brand name (Sensipar), the calcimimetic cinacalcet sensitizes the parathyroid cells to the extracellular calcium signal, suppressing parathyroid hormone (PTH) release and synthesis and preventing parathyroid cell proliferation. This primary PTH suppression decreases the release of calcium and phosphate from bone without increasing intestinal absorption of calcium and phosphate. Therefore cinacalcet decreases the risk of hypercalcemia and hyperphosphatemia in contrast to 1alpha-OH vitamin D derivatives.
