Obstructive oligo-anuria revealing pelvic gynecological cancers, analysis of a series of 102 cases.

INTRODUCTION: Obstructive Anuria (OA) constitutes a diagnostic and therapeutic emergency involving the vital prognosis of the patient requiring an emergency and multidisciplinary care. The etiologies are multiple and the pelvic gynecological cancers represent one of the main causes of OA. OBJECTIVES: Describing the epidemiological, clinical, paraclinical, etiological, therapeutic and progressive aspects of obstructive anuria of the gynecological origin, in the urology department in the University Hospital Center. MATERIALS AND METHODS: This is a descriptive and retrospective study spread over a period of 4 years (2016-2019) including all the patients admitted for management of OA secondary to the pelvic gynecological cancers. RESULTS: 102 patients were included in the study whose the mean age was 60 years old (36-84). The main etiologies were cervical cancer (93%), followed by endometrial cancer (5%) and ovarian cancer (2%). The mean time to consultation was 4.5 days (1-8). The main circumstances of discovery were anuria (67%), oligoanuria (21.5%), low back pain (17%) and hematuria (9%). Clinical examination found an altered general condition (Performans Status> 2) in 37.5% of the patients and an advanced local state in 96% of the patients. The means of serum creatinine and blood urea were 122 mg/l and 2.4 g/l respectively. The hemodialysis (HD) was indicated in 29.5% of patients with life-threatening hyperkalemia (Kalemia> 6.4meq/l) with cardiac distress (20.5%), hydro-sodium overload (6%) and metabolic acidosis (3%). The ultrasound-guided percutaneous nephrostomy was the main method of diversion (92%) followed by the placement of the double J stent (8%). The outcome was favorable in the majority of patients with normalization of the kidney function (88%) while 7% of cases kept chronic kidney disease. The main complication was an obstruction syndrome (41%), followed by infections of the percutaneous nephrostomy tubes (13%) and venous thrombosis of the lower limbs (3%). In addition, the mortality was estimated at 5%. CONCLUSION: The obstructive anuria constitutes a medico-surgical emergency involving the patient's vital prognosis. Our study notes the frequent association between the pelvic gynecological tumors and the obstructive anuria, which can be explained by the advanced stage of these tumors. This work underlines the fundamental interest of early diagnosis of these tumors to enable the prevention of the OA.

Comparison of prevention methods of intradialytic hypotension.

Our study evaluates the effectiveness of the different methods of prevention of intradialytic hypotension (IDH). We studied 16 hemodialysis patients who developed IDH at Ibn Rochd University Hospital. Each patient underwent three standard sessions with cellulose diacetate dialysers and bicarbonate dialysate with calcium concentration of 1.75 mmol/L and sodium (Na) concentration of 140 mmol/L, with dialysate temperature (T) of 37 degrees C. Then the patients were subjected to five successive sessions, each time using one of the following protocols: fixed Na dialysate concentration at 144 mmol/L, Na ramping from 152 to 138 mmol/L, one hour of ultrafiltration (UF) alone followed by three hours of standard dialysis session, dialysis with standard dialysate at T o C, or a combination of Na ramping and cold dialysate. Twelve (78%) patients underwent two sessions of HD per week of five hours each. The mean systolic blood pressure (SAP) in the interdialytic period was 110.7 (100.1-125.5) mmHg; two patients underwent anti-hypertensive treatment. The combination of ramping Na and cold dialysate as well as the cold dialysate were associated with fewer episodes of hypotension in comparison with the standard dialysate. We conclude that the combination modulation of Na and cold dialysate as well as the cold dialysate are the most effective techniques to decrease the number of IDH episodes and the average number of interventions.

A randomized trial of intermittent versus continuous oral alfacalcidol treatment of hyperparathyroidism in end-stage renal disease.

BACKGROUND: Secondary hyperparathyroidism, a major clinical problem in patients with chronic renal failure, develops in response to phosphate retention and impaired calcitriol [1,25-dihydroxyvitamin D3] synthesis. Vitamin D therapy, particularly alfacalcidol [1 alpha-hydroxyvitamin D3], has been shown to be effective in the treatment of secondary hyperparathyroidism. The aim of this study was to compare the effect of a 12-week course of continuous versus intermittent oral alfacalcidol therapy on parathyroid hormone suppression. PATIENTS AND METHODS: 34 patients were selected and randomly divided into 2 groups to receive either intermittent or continuous oral alfacalcidol. Baseline data were obtained on serum calcium, phosphorus, alkaline phosphatase and PTH. All but the PTH were monitored monthly. PTH levels were measured again until the end of the protocol. The intervention was 2 microg of alfacalcidol given after each dialysis session (intermittent group) or 1 microg given 6 days/week (continuous group). RESULTS: Serum calcium and phosphorus showed a tendency to increase from baseline levels in both groups. Mean PTH levels for both groups showed a progressive reduction over time during the study period. This decrement showed no significant difference with regard to the schedule of alfacalcidol administration when comparing the 2 groups. There also was no difference in the incidence of side effects--hypercalcemia and hyperphosphatemia--between the intermittent and continuous intervention. CONCLUSION: Feedback regulation of PTH with oral alfacalcidol therapy is efficient in the treatment of hyperparathyroidism. However, intermittent and continuous oral administration are equally effective in suppressing an elevated PTH level in hemodialysis patients, with similar safety margins.

Diabetic nephropathy in hemodialysis patients in casablanca.

Diabetes is the main cause of end-stage renal disease (ESRD) in the developed countries and its prevalence and incidence have been constantly increasing over the years. To determine the prevalence and profile of diabetic nephropathy in our ESRD population, we retrospectively studied 564 hemodialysis patients in ten dialysis units in Casablanca. The mean age was 49 +/-16.2 years. The diabetic nephropathy came at the third rank with a prevalence of 13.5% behind chronic glomerulonephritis (21.8%) and hypertensive nephropathy (14.7%). Almost 74% of our diabetics were type 2. From the time of diagnosis the type 2 diabetics reached the ESRD earlier than the type 1 diabetics with a mean period of 15.1 +/- 7 years and 18.8 +/- 5 years, respectively; however, the difference was not statistically significant. There was at least another microangiopathic complication in 95.4% of the patients and macroangiopathic complication in 82%. The median hemoglobin A1C in all patients was higher than normal value. We conclude that ESRD is a serious complication of diabetes, which is constantly increasing. The appropriate management of diabetes and a multidisciplinary approach are necessary to avoid it or at least delay its occurrence.

[Ossifying fibroma of the face and hyperparathyroidism in a chronic hemodialysis patient]. / Fibrome ossifiant de la face et hyperparathyroïdie chez une hémodialysée chronique.

The bony complications in secondary hyperparathyroidism in chronic renal failure are varied. The ossifying fibroma is a rare manifestation. We report a case of a 40 years old woman with indeterminate nephropathy undergoing hemodialysis since 1982. Since may 1995, the patient had a diffuse and intensive bone pain of the two inferior members inducing functional importance with apparition of endobuccal tumefaction in the hard palate with an important increase of the volume of the maxillo-mandibular complex six months later associated to disturbances of the deglutition and phonation. In december 1995, the serum parathyroid hormone level is measured at 1527.6 pg/ml and the serum alkaline phosphatase level at 1620 UI/l. The bony lesions are disseminated to all the skeleton in the form of a demineralization with an ossifying expansive process affecting the maxillo-mandibular complex. Calcemia was at 2.3 mmol/l and phosphoremia at 2.1 mmol/l. The surgical biopsy of this pseudotumor showed an aspect of ossifying fibroma. The cervical echography showed a left inferior parathyroid nodular. In june 1996, a subtotal parathyroidectomy was done. The 9th day after surgery, the serum parathyroid hormone level was at 103 pg/ml with normal calcemia and phosphoremia. Five years later, the volume of the tumor reduced moderately. This observation induces 3 commentaries: the bony manifestations associated to secondary hyperparathyroidism have sometimes a tumoral aspect, the ossifying fibroma may be for known as well as the brown tumor and the treatment of these tumors in complex justifying furthermore a rigorous prevention of the hyperparathyroidism in hemodialyzed patients.

[Renal involvement in Behçet's disease. About six cases]. / L'atteinte rénale au cours de la maladie de Behçet. A propos de six observations.

PURPOSE: To analyze anatomoclinic and evolutive aspects of the renal involvement associated to the Behçet's disease through 6 observations collected in the nephrology department from 1985 to 2000 and to make a review of the literature. METHODS: Retrospective study, diagnosis of Behçet's disease according to the Classification of the International Group Study on the Behçet's disease and renal damage confirmed by histology. RESULTS: Our patients all male are aged between 25 to 55 years with a mean at 34 years old. The renal damage was revelated by a nephrotic syndrome in 3 cases and by a proteinuria at 1 to 2.7 g/day in 3 cases. Microscopic hematuria was present in 2 cases and arterial hypertension in 2 cases. The renal insufficiency has been noted in 2 cases of which severe in one of them. The renal biopsy showed an amyloidosis AA type in 3 cases, a segmental and focal glomerulonephritis in 2 cases and a thrombotic microangiopathy associated to a moderate tubulo-interstitiel lesions by toxicity of ciclosporine in 1 case. The extrarenal signs were dominated by bipolar aphtosis in all cases, necrotic pseudofolliculitis and the no specific cutaneous hyperreactivity in 5 cases and the erythema nodosum in 1 case. The ocular manifestation has been noted in 4 cases and articular manifestation in 3 cases. The vascular manifestation has been noted in one case. The treatment was colchicine in 4 cases and prednisone and cyclophosphamide in 1 case. Three patients were lost of view and a patient died in hemodialysis. The 2 other patients with amylosis had persistent proteinuria with a normal renal function. CONCLUSION: The kidney is one of organs that can alter the prognosis of the Behçet's disease; so, its screening must be realised in each patient with this disease.

Rhabdomyolysis and acute renal failure secondary to toxic material abuse in morocco.

We have studied 26 patients with rhabdomyolysis complicated with acute renal failure. The causes of rhabdomyolysis were dominated by paraphenylene diamine intoxication (PPD) (13 cases). The other etiologies were: crush syndrome (6 cases), eclampsia (3 cases), intense physical effort (1 case), butane intoxication (1 case), postural rhabdomyolysis induced by a prolonged surgical operation for pheochromocytoma (1 case). None of the patients had any past medical history of muscle or renal disease. Serum level of creatinine phosphokinase varied from 1200 to 5400 IU/L. The mean peak of serum creatinine level was 620 umol/1. Therapy included forced alkaline diuresis in all cases. Hemodialysis was required in 18 cases. All but eight patients survived. We conclude that rahabdomyolysis could be caused by intoxication, which was a prime cause in this study. Prevention may be possible with restriction of use of toxic products.

[Tuberculosis in hemodialysis]. / La tuberculose des hémodialysés.

The authors report a retrospective study in order to illustrate the particular features of tuberculosis in hemodialysis population. Thirty two patients over 203 (15.8%) in periodic hemodialysis, have presented a tuberculosis between 1983 and 1996. There were 17 men and 15 women aged from 14 to 60 years old. The features of the tuberculosis in these cases were marked by the extrapulmonary localizations (50%) notably nodes tuberculosis, and the difficulties of the diagnosis certainty. The diagnosis was suspected basing on the fever, the weigh loss, the rate sedimentation increase and the radiologic lesions in pulmonary tuberculosis and peripheric or deep lymph nodes involvement. The diagnosis confirmation was established bacteriologically in 6 cases (18.7%) and histologically in 14 cases (43.8%). The treatment consisted on the association of isoniazide, rifampicin and pyrazinamide which leads to recovery in 87.5%. This treatment was a diagnosis proof in the absence of confirmation.
