Calciphylaxie : une complication grave et méconnue de l'insuffisance rénale chronique terminale. À propos de deux cas
2005
Calciphylaxis presents like subcutaneous lesions with livedo reticularis leading to necrotic and painful ulcers, predominantly in the lower limbs and the abdomen. They initially simulate dermohypodermitis. Biology reveals secondary hyperparathyroidism, phosphocalcic metabolism abnormalities and state of hypercoagulability. Histological signs are constant: calcifications in the media of small and sub-cutaneous arteries, intimal hyperplasia and intravascular thrombosis. This complication occurs in 4% of end-stage renal disease patients. Its prognostic is awful with a rate of mortality of 60% due to sepsis. Treatment is based upon the normalization of phosphocalcic rates and local debridement.
A Case of Epididymo-orchitis after intravesical bacille Calmette-Guérin therapy for superficial bladder carcinoma in a patient with latent tuberculos…
2016
Background: Intravesical instillation of bacille Calmette-Guérin (BCG) has been established as efficient therapy for superficial bladder carcinoma. Overall, intravesical BCG is well tolerated and results in complications of less than 5 %. However, adverse effects such as granulomatous prostatitis, pneumonitis, hepatitis, sepsis, and hypersensitivity reactions may occur. The reported rate for tuberculous orchitis after BCG intravesical therapy is 0.4 %. Findings: We report a case of monolateral tuberculous orchitis occurring one month after the second course of intravescical instillation of bacille Calmette-Guérin in a patient with proven superficial bladder carcinoma and latent tuberculosis…
Effects of canagliflozin on serum potassium in people with diabetes and chronic kidney disease: the CREDENCE trial
2021
Abstract Aims Hyperkalaemia is a common complication of type 2 diabetes mellitus (T2DM) and limits the optimal use of agents that block the renin–angiotensin–aldosterone system, particularly in patients with chronic kidney disease (CKD). In patients with CKD, sodium‒glucose cotransporter 2 (SGLT2) inhibitors provide cardiorenal protection, but whether they affect the risk of hyperkalaemia remains uncertain. Methods and results The CREDENCE trial randomized 4401 participants with T2DM and CKD to the SGLT2 inhibitor canagliflozin or matching placebo. In this post hoc analysis using an intention-to-treat approach, we assessed the effect of canagliflozin on a composite outcome of time to eith…
Simulation of left ventricular outflow tract (LVOT) obstruction in transcatheter mitral valve-in-ring replacement.
2020
Left ventricular outflow tract (LVOT) obstruction is a feared complication of transcatheter mitral valve replacement (TMVR). This procedure leads to an elongation of LVOT in the left ventricle (namely, the neoLVOT), ultimately portending hemodynamic impairment and death. This study sought to understand the biomechanical implications of LVOT obstruction in two patients who underwent TMVR as an "off-label" application of the Edwards SAPIEN 3 (S3) Ultra transcatheter heart valve (THV). A computational framework of TMVR was developed to assess the neoLVOT area and quantify the sub-aortic flow structure. We observed that the annuloplasty ring serves as the key anchor zone of S3 Ultra THV. A good…
Iatrogenic pulmonary artery dissection in patient with ostium secundum interatrial septum defect
2020
Pulmonary artery dissection is a rare and lethal condition. Few cases are reported in the literature, and most are derived from autopsies. In most cases, pulmonary artery dissection is a complication of chronic pulmonary hypertension leading to pulmonary artery aneurysm but there are other causes. We describe a case of iatrogenic pulmonary artery dissection in an elderly patient with ostium secundum defect. In particular, we describe the role of cardiac magnetic resonance in making this diagnosis and guiding future therapeutic decisions.
Surgical management of moderate ischemic mitral valve regurgitation: Where do we stand?
2014
Ischemic mitral regurgitation (IMR) represents a common complication after myocardial infarction. The valve is anatomically normal and the incompetence is the result of papillary muscles displacement and annular dilatation, causing leaflets tethering. Functionally the leaflets present a restricted systolic motion due to tethering forces that displaces the coaptation surface toward the left ventricle apex. The patients present poor left ventricular function at the time of surgery and the severity of the mitral regurgitation increases the risk of mortality. Currently there is general agreement to treat surgically severe IMR nevertheless strong evidences for patient with moderate insufficiency…
Incidence of peripheral intravenous catheter failure and complications in paediatric patients: Systematic review and meta analysis.
2020
Background: Most paediatric patients have at least one peripheral intravenous catheter insertion during their hospitalisation. Despite the important function of peripheral intravenous catheters for delivery of intravenous therapy, failure and complications rates are widely reported; however these results have not been synthesised. Objective: To provide an overall estimate of peripheral intravenous catheter failure and related complications in the paediatric population. Design: Systematic review and meta-analysis Data sources: The electronic databases, Cochrane Central Register of Controlled Trials, US National Library of Medicine National Institutes of Health, Cumulative Index of Nursing an…
A life-threatening complication of parenteral nutrition: how to prevent cardiac tamponade?
2014
Complications caused by incorrect central venous insertion are numerous. Cardiac tamponade is a rare, but well-documented complication that is often lethal. We present the case of a patient with cardiac tamponade caused by incorrect tip position and infusion of hyperosmolar fluids such as for parenteral nutrition.
Focus on functional delayed central sleep apnea following cervical laminectomy. An example of respiratory dysfunction in restorative neurosurgical pr…
2017
In sleep-related breathing disorders, sleep apnea is a clinical symptom that can be categorized as obstructive sleep apnea (OSA) or mixed apnea by analysis using poly-somnography. The occurrence of delayed central sleep apnea (CSA) is an extremely rare complication of cervical laminectomy for spondylotic myelopathy. So far only three studies concerning such an event have been reported in the literature. Naim-ur-Rahman, in 1994, reported a case of postoperative CSA following C3-C6 laminectomy, and Visocchi and colleagues, in 2014, in two studies, stressed the lack of association with any other neurological sign of spinal cord damage. No definitive mechanism has been recognized so far for del…
Cholangitis prevention in endoscopic Klatskin tumor palliation: air cholangiography technique.
2009
INTRODUCTION: Endoscopic biliary drainage is the treatment of choice for inoperable hilar cholangiocarcinoma (so-called Klatskin tumor). Cholangitis is the main complication post-endoscopic retrograde cholangiopancreatography (ERCP) in Klatskin patients, specially when medium contrast is injected into biliary tree that could not be subsequently drained. Bacterial cholangitis is the principal cause of mortality in these patients. The aim of this study is to analyze cholangitis rate resulting from the use of air versus iodine contrast to obtain cholangiography during ERCP. METHODS: In 9 years, 188 inoperable Klatskin patients were recruited and divided into two groups: iodine (A) or air (B) c…
