[Pycnodysostosis: about a case].

Pycnodysostosis is a very rare genetic disease of the bone characterized by osteocondensation associated with dysmorphic syndrome and growth retardation. This study aims to highlight the phenotypic abnormalities, the radiological signs, the therapeutic and evolutionary features of pycnodysostosis in a 11-year old child. The child was referred by his dentist for clinical evaluation.

Rare and unusual case of anti-factor XI antibodies in patient with plasma cell leukemia.

Background: The acquired inhibitors of coagulation have been observed in very rare cases of monoclonal gammopathies. We report a very rare case of anti-factor XI antibodies in patient with plasma cell leukemia (PCL).

Case Presentation: This is a 59-year-old male patient without pathological history, admitted to the nephrology department for management of renal insufficiency and anemia syndrome.

Gastrointestinal bleeding due to angiodysplasia in patients on hemodialysis: A single-center study.

Gastrointestinal (GI) bleeding due to angiodysplastic lesions is a common problem among patients receiving hemodialysis (HD). We studied 22 HD patients (5 females and 17 males) who had GI bleeding due to angiodysplasia; the mean age of whom was 54 ± 10 years. All patients had upper and lower GI endoscopy.

Consumption of Argan Oil Improves Anti-Oxidant and Lipid Status in Hemodialysis Patients.

Objective: Virgin Argan oil (VAO) is of interest in oxidative stress and lipid profile because of its fat composition and antioxidant compounds. We investigated the effect of VAO consumption on lipid profile and antioxidant status in hemodialysis patients after a 4-week period of consumption.

Methods: In a crossover, controlled trial, 37 patients (18 men, 19 women) with end-stage renal disease on maintenance hemodialysis, were randomly assigned to a 4-week VAO diet.

Effects of lowering dialysate calcium concentration on mineral metabolism and hemodynamic parameters in hemodialysis patients.

Introduction: It has been suggested that a dialysate calcium concentration of 1.5 mmol/L is a compromise between bone protection and cardiovascular risk. This study aimed to investigate the effect of reducing dialysate calcium concentration to 1.

Angio-embolization of a renal pseudoaneurysm complicating a percutaneous renal biopsy: a case report.

We report the treatment of a bleeding renal pseudoaneurysm by angio-embolization. A 21 years old woman developed macroscopic haematuria following renal biopsy. Renal angio-scan showed a 1.

Experience in using thermal disinfection to remove viable bacteria and endotoxins in centraly distributed reverse osmosis water.

Introduction: The water used for dilution of hemodialysis concentrates has to meet official quality recommendations regarding microbiology and chemical parameters. To avoid chemical use and to simplify treatments, hot water has been used to control microbial contamination of water distribution systems. In this study we evaluated the efficacy of heat disinfection in maintaining the quality of dialysis water generated by reverse osmosis (RO).

[Late pneumomediastinum revealed by acute pulmonary edema in hemodialysis].

Central venous catheterization occupies an important place in the treatment of end stage renal disease pending the creation of an arteriovenous fistula. However, this procedure is not devoid of complications. We report a case of late pneumomediastinum revealed by an acute pulmonary edema in a young patient on hemodialysis, and we discuss its characteristics.

Serum tumor markers in hemodialysis patients.

Aims: The main objective of this work was to evaluate the influence of end-stage renal disease (ESRD) on concentrations of five tumor markers (TMs): carcinoembryonic antigen (CEA), carbohydrate antigen (CA) 19-9 (CA19-9), CA15-3, CA125, and prostate specific antigen (PSA) in a group of chronic hemodialysis patients (CHPs); and to study the influence of hemodialysis (HD) sessions on concentrations of the same TMs.

Methods: We compared TMs levels in CHP before HD sessions to a control group of 50 healthy volunteers, the dosages were determined before and immediately after the HD session Comparisons were made before and after correction for dialysis-induced hemoconcentrations.

Results: We enrolled 74 CHPs, all TM concentrations were higher in this group compared to control group, but this increase was significant for CEA (4.

Scleroderma renal crisis precipitated by steroid treatment in systemic lupus erythematosus and scleroderma overlap syndrome.

Introduction: Connective tissue disorders can overlap in various ways. Patients may present with features of more than one specific disease without satisfying the diagnostic criteria and thereafter evolve into a specific disease entity. Occasionally, patients may fulfil simultaneously the diagnostic criteria of two or more diseases.

A model to calculate cardiac output in hemodialysis patients by thermodilution.

The Blood Temperature Monitor module (BTM) is used to measure recirculation by thermodilution in dialysis. Numerous studies have confirmed its interest in the measuring of the vascular access flow. In this letter we describe a model to calculate cardiac output in dialysis by the BTM.

A model to predict optimal dialysate flow.

Diffusive clearance depends on blood (Qb) and dialysate flow (Qd) rates and the overall mass transfer area coefficient (KoA) of the dialyzer. In this article we describe a model to predict an appropriated AutoFlow (AF) factor (AF factor = Ratio Qd/Qb), that is able to provide adequate Kt/V for hemodialysis patients (HDP), while consuming lower amounts of dialysate, water and energy during the treatment. We studied in vivo the effects of three various Qd on the delivered dose of dialysis in 33 stable HDP.

Pregnancy during hemodialysis: a single center experience.

Successful pregnancy outcome is an uncommon occurrence in women requiring chronic dialysis treatment. We reviewed the course and outcome of 9 pregnancies occurred in women on chronic hemodialysis in our center from 1999-2007; 5 of them ended with delivery of alive newborns, 2 with fetal deaths in-utero, and 2 with abortions. The average age of patients was 34 years.
