Vascularite rhumatoïde et autres complications systémiques: aspects diagnostique et thérapeutique [Diagnosis and treatment of rheumatoid vasculitis and other systemic complications of rheumatoid arthritis]

Rheumatoid arthritis is a systemic disease that can potentially affect any organ. If the articular manifestations are central to the disease; skin, ophthalmic, neurological, cardiac, pulmonary as well as renal manifestations are well recognized, the latter particularly in the context of a secondary amyloidosis. Although incidence of extraarticular manifestations appears to decrease, likely a result from our more aggressive and early management of rheumatoid arthritis, their consequences remain severe in terms of morbidity and mortality, and their treatments complicated. The new biological therapies seem to be a promising alternative to current therapies, such as cyclophosphamide and high dose prednisone, even if evidences are still limited.

Schizophrenia and complications of pregnancy and labor: an individual patient data meta-analysis.

Several epidemiological studies have reported an association between complications of pregnancy and delivery and schizophrenia, but none have had sufficient power to examine specific complications that, individually, are of low prevalence. We, therefore, performed an individual patient meta-analysis using the raw data from case control studies that used the Lewis-Murray scale. Data were obtained from 12 studies on 700 schizophrenia subjects and 835 controls. There were significant associations between schizophrenia and premature rupture of membranes, gestational age shorter than 37 weeks, and use of resuscitation or incubator. There were associations of borderline significance between schizophrenia and birthweight lower than 2,500 g and forceps delivery. There was no significant interaction between these complications and sex. We conclude that some abnormalities of pregnancy and delivery may be associated with development of schizophrenia. The pathophysiology may involve hypoxia and so future studies should focus on the accurate measurement of this exposure.

Complications of Valve Lung Volume Reduction in a Case of Previous Pleurodesis.

Lung volume reduction with valves is increasingly used to treat selected patients with severe emphysema. The indications for this procedure have been previously described; however, its contraindications have not yet been conclusively established. This case highlights the potentially severe complications of endobronchial one-way valve placement in the setting of a previous pleurodesis.

Duodénopancréatectomie céphalique: indications, résultats et prise en charge des complications [Pancreaticoduodenectomy: indications, results and management of complications]

Pancreaticoduodenectomy is a major procedure in visceral surgery. Post-operative mortality is around 5% in high-volume hospitals, thanks to improvement in global patients care. Morbidity remains high though. The treatment of complications most often require a multidisciplinary approach. Delayed gastric emptying, intraabdominal abscesses and pancreatic fistulas are the most frequent complications. Post-pancreatectomy hemorrhage, although more rare, is a severe and dreadful event. Despite its morbidity, duodenopancreatectomy significantly improves survival of patients with biliopancreatic cancer. Early recognition of these complications and a prompt treatment increase the safety of this procedure.

Retrospective analysis of complications of immunosuppressive therapies (steroidsand immunosuppressive therapies) in pediatric uveitis

Purpose¦The purpose of this study is to analyze the incidence rate of side effects occurring during systemic therapy (corticosteroids, methotrexate, azathioprine, cyclosporine A or biologic agents) of auto-immune uveitis.¦Material and methods¦Retrospective study including 23 / 71 patients aged between 0-16 years old presenting with a chronic non-infectious uveitis. All children were treated in the Jules-Gonin Eye Hospital and paediatric rheumatology unit of the CHUV (Centre Hospitalier Universitaire Vaudois) between January 2000 and December 31st 2010. Side effects were reported as minor (without subsequent change in systemic medication), moderate (associated with a change in systemic dosage or class of immunosuppressive therapy or in the presence of Cushingoid face or weight gain) or severe (hospitalization or life threatening).¦Results¦52% of boys and 48% of girls are present in the cohort with a mean age at the first visit of 8.1 years (1.7-15.6). Intermediate uveitis consisted of the commonest aetiology with 8 patients (35%), juvenile idiopathic arthritis (JIA) in 7 (30%), Behçet's disease in 3 (13%) and others in 5 (22%). The overall length of therapy was longer for prednisone (26.6 ± 5.4 patient / year), but was similar between methotrexate (22.1 ± 5.4 patient / year) and azathioprine (15.2 patient / year). Moderate side effects were respectively 64% for corticosteroids therapy, 54% with methotrexate and 14% with azathioprine. One severe and one moderate side effect were observed with anti-TNFα respectively stage III anaphylactic shock and pain during injection associated with a redness of the site of injection and limping after the injection.¦Discussion¦Immunomodulating agents allow a rapid decrease in corticosteroid therapy, but one severe side effect was observed with anti-TNFa agents. These agents are considered in most countries as third line therapeutic agents.

Psychotropic drug-induced weight gain and other metabolic complications in a Swiss psychiatric population.

PURPOSE: To describe the weight gain-related side-effects of psychotropic drugs and their consequences on metabolic complications (hypercholesterolemia, obesity) in a Swiss cohort of psychiatric patients. METHOD: This cross-sectional observational study was performed in an out-patient psychiatric division with patients having received for more than 3 months the following drugs: clozapine, olanzapine, quetiapine, risperidone, lithium, and/or valproate. Clinical measures and lifestyle information (smoking behaviour, physical activity) were recorded. RESULTS: 196 inclusions were completed. Weight gain (≥10% of initial weight) following drug treatment was reported in 47% of these patients. Prevalence of obesity (BMI ≥ 30), hypercholesterolemia (≥6.2 mmol/L) and low HDL-cholesterol (<1.0 mmol/L in men, <1.3 mmol/L in women) were present in 38%, 21%, and 27% of patients, respectively. A higher standardised dose, an increase of appetite following medication introduction, the type of medication (clozapine or olanzapine > quetiapine or risperidone > lithium or valproate), and the gender were shown to be significantly associated with evolution of BMI. CONCLUSION: High prevalence of obesity and hypercholesterolemia was found in an out-patient psychiatric population and confirms drug-induced weight gain complications during long-term treatment. The results support the recently published recommendations of monitoring of metabolic side-effects during treatment with atypical antipsychotics. Moreover, the weight gain predictors found in the present study could help to highlight patients with special health care management requirement.

Urological complications in renal transplantation from cadaveric donor grafts: a retrospective analysis of 20 years.

INTRODUCTION: This study is a retrospective analysis of ureteral complications and their management from a monocenter series of 277 consecutive renal transplantations. MATERIALS AND METHODS: From September 1979 to June 1999, 277 renal transplantations (cadaveric origin) were performed in 241 patients. The ureter from the kidney graft was inserted into the bladder according to the technique of extravesical implantation described by Lich-Gregoir and Campos-Freire. The study analyzed the time of occurrence and the type of complications observed. The different procedures to restore the transplanted urinary tract are presented. RESULTS: Complications occurred in 43/277 renal transplantations (15.5%). Anastomotic urine leakage or ureteral stricture were the most frequent. The time to appearance of these complications was either short (<1 month) or late (>1 month) in a similar number of cases. Most cases were managed surgically: 33/43 cases (76.7%). The most frequent surgical repair was ureterovesical reimplantation (n=13), followed by: ureteroureteral end-to-end anastomosis (native ureter-ureter transplant, n=5); pyeloureteral anastomosis (native ureter-renal pelvis transplant, n=5); simple revision of ureterovesical implantation (n=4); resection and end-to-end anastomosis of the transplant ureter (n=2); calico-vesicostomy (graft-bladder, n=1); implantation according to Boari (n=1); pyelovesicostomy with bipartition of bladder (n=1), and pyeloileocystoplasty with detubularized ileal graft (n=1). No deaths related to any of the urological complications were reported. However, 2 consecutive vesico-renal refluxes led to the loss of the kidney graft in the long-term. CONCLUSION: The rate of complications observed in this retrospective analysis is similar to the experience of other studies, ranging from 2 to 20%. If the classical extravesical ureteral bladder implantation is to remain an attractive technique due to its simplicity, the surgical team at the training center should be aware of all the means to prevent any ureteral complications, such as the choice of another implantation technique and/or insertion of a transient ureteral stent.

Risque de complications lors de menaces d'accouchement inopiné en préhospitalier

Introduction: Les accouchements inopinés en pré-hospitaliercomportent un risque notable de complications maternelles, enparticulier hémorragiques, et sont grevés d'une mortalité néonatalesérieuse.Méthode: Analyse rétrospective des interventions SMUR pour menaced'accouchement, avec description des caractéristiquesdémographiques et médicales, ainsi que des complications recensées.Résultats: Entre 2003 et 2010, 88 menaces d'accouchements (0,8%du total des missions) ont été recensées. Les situations sont survenuesà domicile dans 85% des cas (lieu public: 10%). Dans 45% des cas,l'intervention a eu lieu durant la soirée ou la nuit. L'âge moyen despatientes était de 31 ans ± 3,8 (IC 95% 15-43 ans). Dans 57% des cas,l'accouchement est intervenu en préhospitalier. La délivranceplacentaire est par contre survenue avant l'arrivée à l'hôpital dansseulement 10% des cas. Ce résultat est à mettre en lien avec descourtes durées de prise en charge préhospitalière (médiane 34,6 min,IC 95% 10-107 min). 90% des patientes ont bénéficié d'une perfusionintraveineuse (échec de pose: 8 cas), avec un volume de liquide <500ml dans 78% des cas. Une hémorragie maternelle >500 ml estsurvenue dans 13 cas (14,7%) et une réanimation néonatale a étéinitiée dans 4 cas, avec trois décès de nouveau-nés.Conclusions: L'accouchement inopiné à domicile comporte un risqueimportant de complications materno-foetales et nécessite une formationspécifique des équipages SMUR.

Les complications de la cirrhose hépatique: varices oesophagiennes, ascite et carcinome hépato-cellulaire [Complications of liver cirrhosis: oesophageal varices, ascites and hepato-cellular carcinoma]

The principal treatment for bleeding oesophageal varices is endoscopic ligation. Non-cardioselective beta-blockers are the gold-standard of primary prophylaxis. The principal treatment for ascites is a salt-free diet and diuretics, mainly spironolactone, if necessary associated with a loop diuretic. In refractory ascites, paracentesis or installation of a transjugular intrahepatic portosystemic shunt (TIPS) are two possible treatment options. Cirrhosis patients are at higher risk of developing hepato-cellular carcinoma. Surgery is only possible in a small number of cases. Percutaneous destruction techniques have nearly the same survival rate as that obtained by surgery and should be proposed to patients where surgery is not an option.

Early mobilization out of bed after ischaemic stroke reduces severe complications but not cerebral blood flow: a randomized controlled pilot trial.

OBJECTIVE: To evaluate whether early mobilization after acute ischaemic stroke is better than delayed mobilization with regard to medical complications and if it is safe in relation to neurological function and cerebral blood flow. DESIGN: Randomized controlled pilot trial of early versus delayed mobilization out of bed with incidence of severe complications as the primary outcome. SETTING: Acute stroke unit in the neurology department of a University Hospital. PARTICIPANTS: Fifty patients after ischaemic stroke with a National Institutes of Health Stroke Scale (NIHSS) score >6 were recruited. INTERVENTION: All patients were treated with physiotherapy immediately after their admission. In the early protocol patients were mobilized out of bed after 52 hours, in the delayed protocol after seven days. RESULTS: Eight out of 50 randomized patients were excluded from the per-protocol analysis because of early transfer to other hospitals. There were 2 (8%) severe complications in the 25 early mobilization patients and 8 (47%) in the 17 delayed mobilization patients (P < 0.006). There were no differences in the total number of complications or in clinical outcome. In the 26 patients (62%) who underwent serial transcranial Doppler ultrasonography, no blood flow differences were found. CONCLUSION: We found an apparent reduction in severe complications and no increase in total complications with an early mobilization protocol after acute ischaemic stroke. No influence on neurological three-month outcomes or on cerebral blood flow was seen. These results justify larger trials comparing mobilization protocols with possibly even faster mobilization out of bed than explored here.

EORTC topics in neurooncology: The long path from a focus on neurological complications of cancer towards molecularly defined trials and therapies in neurooncology

Over the past decade a series of trials of the EORTC Brain Tumor Group (BTG) has substantially influenced and shaped the standard-of-care of primary brain tumors. All these trials were coupled with biological research that has allowed for better understanding of the biology of these tumors. In glioblastoma, EORTC trial 26981/22981 conducted jointly with the National Cancer Institute of Canada Clinical Trials Group showed superiority of concomitant radiochemotherapy with temozolomide over radiotherapy alone. It also identified the first predictive marker for benefit from alkylating agent chemotherapy in glioblastoma, the methylation of the O6-methyl-guanyl-methly-transferase (MGMT) gene promoter. In another large randomized trial, EORTC 26951, adjuvant chemotherapy in anaplastic oligodendroglial tumors was investigated. Despite an improvement in progression-free survival this did not translate into a survival benefit. The third example of a landmark trial is the EORTC 22845 trial. This trial led by the EORTC Radiation Oncology Group forms the basis for an expectative approach to patients with low-grade glioma, as early radiotherapy indeed prolongs time to tumor progression but with no benefit in overall survival. This trial is the key reference in deciding at what time in their disease adult patients with low-grade glioma should be irradiated. Future initiatives will continue to focus on the conduct of controlled trials, rational academic drug development as well as systematic evaluation of tumor tissue including biomarker development for personalized therapy. Important lessons learned in neurooncology are to dare to ask real questions rather than merely rapidly testing new compounds, and the value of well designed trials, including the presence of controls, central pathology review, strict radiology protocols and biobanking. Structurally, the EORTC BTG has evolved into a multidisciplinary group with strong transatlantic alliances. It has contributed to the maturation of neurooncology within the oncological sciences.

Are patients at nutritional risk more prone to complications after major urological surgery?

PURPOSE: The nutritional risk score is a recommended screening tool for malnutrition. While a nutritional risk score of 3 or greater predicts adverse outcomes after digestive surgery, to our knowledge its predictive value for morbidity after urological interventions is unknown. We determined whether urological patients at nutritional risk are at higher risk for complications after major surgery than patients not at nutritional risk. MATERIALS AND METHODS: We performed a prospective observational study in consecutive patients undergoing major surgery. A priori sample calculation resulted in a study cohort of 220 patients. Interim analysis was planned after 110 patients. The nutritional risk score was assessed preoperatively by a specialized study nurse. Nutritional care was standardized in all patients. Postoperative complications were defined previously using the standardized Dindo-Clavien classification. The primary end point was 30-day morbidity. Univariate and multivariate analysis was performed to identify predictors of complications. RESULTS: The study was discontinued due to significant results after interim analysis. A total of 125 patients were included in analysis from June 2011 to June 2012 and 15 were excluded because of incomplete data. Of 51 patients at nutritional risk 38 (74%) presented with at least 1 complication compared to 28 of 59 controls (47%). Patients at nutritional risk were at threefold risk for complications on univariate and multivariate analysis (OR 3.3, 95% CI 1.3-8.0). Cystectomy was the only other predictor of morbidity (OR 10, 95% CI 2-48). CONCLUSIONS: Patients at nutritional risk are more prone to complications after major urological procedures. Whether this increased morbidity can be reversed by perioperative nutritional support should be studied.
