Best evidence topic: Is ileocolic anastomotic leak rate higher in handsewn or stapler's anastomosis?

A best evidence topic has been constructed using a described protocol. The three-part question addressed was: is ileocolic anastomotic leak rate higher in handsewn or stapler's anastomosis? Using the reported search, 150 papers were found. 6 studies were deemed to be suitable to answer the question. The outcomes assessed were anastomotic leaks rate in hands Sewn and stapler's ileocolic anastomosis. The evidence does not provide an agreed consensus for which modalities of anastomosis have higher anastomotic leaks rate. Until a high quality randomized control trial is performed, the authors recommend an individual approach in a term of selection of which anastomotic modalities to be used.

Update on pathogenesis, management, and treatment of hypertension in autosomal dominant polycystic kidney disease.

Hypertension is a common early finding in autosomal dominant polycystic kidney disease (ADPKD). Improvements in screening and diagnosis of ADPKD have allowed earlier diagnosis, later onset of end-stage renal disease, and better survival. However, the main and most effective therapy remains control of hypertension. Hypertension is the most important modifiable risk factor in ADPKD. Therefore, early management of hypertension reduces the incidence of cardiovascular events in ADPKD patients. Stimulation of the renin-angiotensin-aldosterone system (RAAS) plays a central role in the pathogenesis of hypertension in ADPKD. Therapies that block the RAAS have improved patient management, blood pressure control, and ADPKD patient survival. This review highlights the current understanding of the epidemiology, potential pathogenetic mechanisms and proposes a strategy for the treatment and management of hypertension in ADPKD.

Erectile dysfunction in hemodialysis patients.

Erectile dysfunction (ED) is a common problem seen among patients on hemodialysis (HD), but it is still a taboo subject in our country. The attention given to this sexual problem remained low, and the prevalence of ED among these patients has not been well characterized. We carried out this study in order to determine the prevalence and severity of ED in HD patients. We conducted a descriptive cross-sectional study in our HD unit in March 2013. ED was evaluated using the International Index Erection Function. Thirty patients with a mean age of 49.1 years were eligible for this study. The main causes of chronic kidney disease were hypertension (62.5%) and diabetes (41.6%). The prevalence of ED was 80%, including 33.3% severe ED. Plasma levels of gonadotropins: luteinizing hormone (LH), follicule-stimulating hormone were in the standards except for one patient who had an elevated level of LH. Prolactin was elevated in four cases. ED was present in 8.4% of patients before the discovery of renal failure and in 91.6% of patients at the beginning of dialysis. For 19 patients (79.1%), the ED had increased during the dialysis sessions. A significant number of our HD patients presented with ED of varying degrees. Nephrologists should pay attention to the problem of ED in order to improve the quality of their life.

Therapeutic efficacy of a biosimilar epoetin alfa in hemodialysis patients.

Anemia is a frequent complication in patients with chronic kidney disease. However, human recombinant erythropoietin (rHu-EPO) has revolutionized the management of anemia in chronically dialyzed patients. Epomax ® is a new rHu-EPO alfa manufactured in Tunisia (Medis Laboratories). The aim of this study was to evaluate the efficacy and tolerance of Epomax ® in chronic hemodialysis (HD) patients in a phase-III, multicenter, clinical trial. Fiftythree HD patients (mean age 47.7 ± 13 years) who received a stable dose of rHu-EPO (Hemax ® , a rHu-EPO alfa manufactured by Biosidus Laboratories) subcutaneously were switched to Epomax ® via the same route of administration. At baseline, the mean systolic pressure was 132 ± 18 mm Hg and the mean diastolic pressure was 79 ± 8 mm Hg. The mean blood hemoglobin was 10.2 g/dL and the median ferritin level was 667 ng/mL. After a follow-up of 43 days, the mean blood hemoglobin was 10.5 g/dL under the effect of Epomax ® . There was no significant difference in the mean hemoglobin levels between the treatments with both drugs. Few adverse events were reported during the study. We conclude that Epomax ® was effective at maintaining the hemoglobin levels at target concentrations and was well tolerated in HD patients.

Systemic sarcoidosis complicated of acute renal failure: about 12 cases.

The sarcoidosis is a systemic granulomatosis affecting most frequently the lungs and the mediastinum. An acute renal failure reveals exceptionally this disease. It's a retrospective study implicating 12 cases of sarcoidosis complicated of acute renal failure. The aim of this study is to determine epidemiological, clinical, biological and histological profile in these cases and then to indicate the interest to consider the diagnosis of sarcoidosis in cases of unexplained renal failure. Extra-renal complications, therapeutic modalities and the outcome were determined in all patients. Our series involved 12 women with an average age of 40 years. Biological investigations showed an abnormal normocalcemia in 7 cases, a hypercalcemia in 5 cases, a hypercalciuria in 10 cases and polyclonal hypergammaglobulinemia in 7 cases. An acute renal failure was found in all patients with a median creatinin of 520 umol/L. For all patients, the renal echography was normal however, the kidney biopsy showed tubulo-interstitial nephritis. The extra-renal signs highlighting pulmonary interstitial syndrome in 5 cases, a sicca syndrome in 4 cases, mediastinal lymph nodes in 2 cases, a lymphocytic alveolitis in 3 cases, an anterior granulomatous uveitis in 2 cases and a polyarthritis in 5 cases. Five patients benefited of hemodialysis. The treatment consisted of corticosteroid in all cases. The follow up was marked by complete resolution of clinical and biological signs. The diagnosis of renal sarcoidosis must be done quickly to prevent renal failure.

Epidemiology and outcome of articular complications in adult onset Still's disease.

The adult onset Still's disease is a rare inflammatory pathology of unknown pathogeny. The clinical features are variable. The diagnosis is difficult since exclusion of infectious, systemic and tumoral pathologies should be done. The articular complications are frequent and can be revelatory of this pathology. The articular prognosis depends on the diagnosis delay and the treatment efficiency. Our study aims to analyze different aspects of articular manifestations complicating adult onset Still disease to define epidemiological, clinical and evolving characteristics of these complications. It was a cross-sectional study concerning 18 cases of adult onset Still disease diagnosed from 1990 to 2014 in the internal medicine A department of Charles Nicolle Hospital in Tunis, meeting Yamaguchi criteria. We identified clinical, radiological, evolving and therapeutic profile of the articular manifestations occurred in these patients. There were 11 women and 7 men. The average age was 27 years. The arthralgias were reported in all cases; while, the arthritis interested thirteen patients. A hand deformation was found in four patients. A wrist ankylosis was noted in one case and a flexion elbow in one patient. The Standard articular radiographs were normal in ten cases. The treatment associated essentially non-steroidal anti-inflammatory and/or corticosteroids and/or methotrexate. Concerning the evolving profile, the monocyclic form was present in 25% of the cases, the intermittent form in 40% and the chronic articular form in 35% of our patients. The adult onset Still's disease is rare and heterogeneous. The articular disturbances are frequent and have various outcomes.

[Renal injury in Takayasu's arteritis]. / Atteinte rénale au cours de la maladie de Takayasu.

Renal involvement in Takayasu's arteritis is frequent and worsens the progression of the disease. This is primarily a renal artery stenosis causing renovascular hypertension. The glomerular disease is exceptional. This study was undertaken to determine the clinical, radiological, biological features and therapeutic response in patients with kidney disease associated with Takayasu arteritis. A retrospective chart review was conducted on 11 patients (five men and six females), with a mean age of 31.1 years (19-40 years). The discovery of kidney disease preceded the diagnosis of Takayasu's arteritis in eight cases. Ten patients developed hypertension. Laboratory finding showed proteinuria in five cases of which one case was due to nephrotic syndrome. Renal failure was found in six cases including four cases in stage of terminal chronic renal failure. Impairment of the renal artery was present in nine patients, proximal in seven cases and distal in two cases, bilateral in five cases and unilateral in four cases. Narrowing renal artery was found in seven cases. The renal biopsy revealed membranoproliferative glomerulonephritis in one case and nephrosclerosis in another case. Eleven patients were followed for an average period of 155 months (3-335 months). Remission of nephrotic syndrome was concomitant with the remission of the disease. Seven patients developed outbreaks of Takayasu's arteritis of which six were in care. Relapse of nephrotic syndrome was concomitant with the outbreak of the disease followed by spontaneous remission of both diseases. Improved pressure was obtained in 5 cases and worsening renal function in seven cases. Death was observed in two cases.

Septic sacroiliitis revealing an infectious endocarditis.

We report the case of a 43-year-old man admitted for right hip ache and fever. Physical examination revealed a fever, an ache at the manipulation of the sacroiliac joint and a limitation of abduction and external rotation of the right hip. There was no murmur in cardiac auscultation. No anomaly was found at the conventional radiographs of the sacroiliac joint, while the pelvic MRI confirmed a right sacroiliitis. A sacroiliac puncture with a study of synovial fluid demonstrated the presence of Streptococcus viridans. The blood culture revealed the same germ. Transthoracic and transoesophageal echocardiography confirmed infectious endocarditis with vegetation in the mitral valve. He received penicillin G and gentamicin relayed by pristinamycin because of an allergy to penicillin G with a total duration of treatment of 40 days. His symptoms and the laboratory and radiological tests abnormalities resolved totally with no recurrence.
