[Bowel injuries after port insertion in laparoscopy. Gynerisq's database analysis]. / Plaies digestives à l'insertion des trocarts en cœlioscopie. Analyse de la base de données de retour d'expérience de Gynerisq.

INTRODUCTION: Port insertion is a high-risk period during laparoscopy. The French Gynecologist and Obstetricians College (CNGOF) published recommendations in 2010 to minimize those risks. The aim of our analysis was to establish the accidents' circumstances and consequences and to determine if those incidents could have been depending on whether recommendations had been respected or not. MATERIAL AND METHODS: Gynerisq is an approved organism by the Haute Autorité de santé (HAS). Its mission is to evaluate and improve practices by a risk management centered approach. We analysed incidents reported by Gynerisq's adherents in an experience report database. RESULTS: Above 114 incidents analysed in the Gynerisq's database, we reported 31 bowel injuries. Those injuries occurred for 77.4% (24/31) during planned interventions. For 32.3% of the cases (10/31), interventions were judged complex by the surgeons. A total of 54.8% (17/31) of the patients had a history of laparotomy. Above 27 injuries occurred during Veress needle or open laparoscopy, 17 could have been avoided regarding to the surgeon. The causes reported were in 10 cases that the recommendations had not been respected, in 2 cases another cause and in 5 cases no causes were given to explain the incident. CONCLUSION: Our analysis shows that bowel injuries after port insertion, in open laparoscopy or Veress needle use, do not seem to occur only in an emergency context or during complicated interventions. However, most of the incidents occurred for patients with risk factors.

[Multicenter study on lumbar puncture indication, clinical practice and feasibility]. / Indications, réalisation et faisabilité de la ponction lombaire dans 18 centres mémoires de ressources et de recherche.

INTRODUCTION: Cerebrospinal fluid (CSF) biomarkers have been extensively studied as diagnostic markers for Alzheimer's disease (AD). However, results are variable probably due to lumbar puncture (LP) procedure, CSF collection and transport. This intercenter variability highlights the need for an efficient standardization of clinical and technical procedures. The aims of this study were firstly to compare the LP procedure and CSF transport process in all French Memory Centers and secondly to evaluate the incidence of LP side effects in 100 patients with cognitive disturbances. METHODS: LP practice and side effect prospective questionnaires were sent to all French Memory Centers in May 2010. Memory Centers were asked about their LP procedure. The prospective study over a three-week-period has evaluated the LP feasibility and side effects. All data were collected until the end of July 2010. RESULTS: The answers of 18 out of 26 Memory Centers were collected. Although, these centers did not have the same LP procedure and CSF transport, the majority of them proceeded according to Innogenetics's advices concerning the use of polypropylene tubes and transport duration but not sample conditioning. Polypropylene tubes were different from one center to the other. CSF volume, pharmacological premedication and prevention of post-LP syndrome were variable in all responding centers. The prospective study carried out in 100 patients revealed a very good LP acceptability (93/100 patients). LP feasibility was 97 % (90/93) and failed LP were consequently performed with success using radiological scopes. Three minor complications were observed. DISCUSSION AND CONCLUSION: All French Centers complied with Innogenetics' recommendations for pretechnical CSF procedures; however each Center put in place its own procedure that was different one center to the other. It will be very interesting to compare cut-off and result values for Aß, tau and phosphorylated tau protein on threonine 181 between several centers that used their own procedures. Acceptability and safety were very good in our short but significant prospective study. These results confirm the data of Zetterberg et al., 2010.

Evolution of blood pressure in patients with Alzheimer's disease: a one year survey of a French Cohort (REAL.FR).

OBJECTIVES: To determine the evolution of blood pressure in patients with moderate Alzheimer's disease among a one year longitudinal survey and to evaluate the relationship between blood pressure and cognitive functions. METHODS: In 327 subjects selected from the French research program on Alzheimer's disease (REAL.FR), systolic and diastolic blood pressure (SBP, DBP) were measured at the time of inclusion (M0), after 6 months (M6) and after 12 months (M12). All subjects were assessed to determine both cognitive functions and capabilities in the activities of daily living using validated cognitive scales [Mini Mental State Examination (MMSE), Alzheimer's Disease Assessment Scale--Cognitive part (ADAS-Cog), Instrumental Activities of Daily Living (IADL), Activities of Daily Living (ADL), Clinical Dementia Rating (CDR)], at M0, M6, M12. RESULTS: In this population of patients with moderate Alzheimer's disease, mean age was 78 +/- 7 years and 242 subjects were females (74%). After adjustment for age, gender, body mass index (BMI) and antihypertensive therapy, a significant decrease of blood pressure was observed between M0 and M12, for SBP (139.1 +/- 18 to 136.5 +/- 17 mmHg, p < 0.05) and DBP, (77.6 +/- 12 to 75.8 +/- 10 mmHg , p < 0.05). Demented subjects with the worst cognitive impairment at baseline (tertile1 MMSE, tertile 3 ADAS-Cog, ADL scores between 0 and 4, CDR scores between 10 to 18) showed a larger decrease in SBP and DBP after 12 months. The worst impairment in dementia at baseline was associated with the highest SBP decrease between M0 and M12 (delta SBP tertile 1 MMSE vs tertile 3 MMSE = -5.9 vs + 1.0 mmHg , p < 0.05; Delta SBP tertile 3 ADAS-Cog vs tertile 1 ADAS-Cog = - 5.98 vs + 2.98 mmHg, p < 0.05, Delta SBP ADL 0-4 vs ADL -6 = - 8.7 vs -1.5 mmHg, p < 0.05, delta SBP CDR 10-18 vs CDR 0.5-9.5 = - 6.9 vs -1.7 mmHg, p < 0.05). All these results persisted after adjustment for age, gender and the antihypertensive therapy. Baseline SBP [OR 95% CI = 1.05 (1.02-1.08), BMI [OR 95% CI = 0.88 (0.81-0.95)], ADL score [OR 95% CI = 0.42 (0.22-0.81)] and ADAS-Cog score [OR 95% CI = 1.07 (1.01-1.14)] were significantly associated with the decrease of blood pressure after one year of follow up, independently of age, gender and antihypertensive therapy. In contrast, patients with larger blood pressure decrease (over 10 mmHg reduction of SBP and/or 5 mmHg of DBP) did not demonstrate a more significant worsening of dementia at 12 months in the different scales used. CONCLUSIONS: This study indicates a significant decrease in blood pressure in patients with Alzheimer's disease after one year of follow up, independently of age, gender, BMI and antihypertensive therapy. The largest decrease in blood pressure was observed in patients with the most severe impairment in dementia at baseline, suggesting that blood pressure decrease seems to be mainly a secondary phenomenon in Alzheimer's disorders.

[Cognitive functions and hypertension]. / Fonctions cognitives et hypertension artérielle.

The prevention of cognitive disorders and dementia represents a major challenge in the coming years. Hypertension is one of the principal risk factors for cerebrovascular diseases and is also closely correlated with cognitive decline and dementia. Most longitudinal studies have shown that cognitive functioning is often inversely proportional to blood pressure values measured 15 or 20 years previously. The higher blood pressure was, the poorer cognitive function is. Data from recent therapeutic trials (SYST-EUR, PROGRESS) open the way toward the prevention of dementia (vascular or Alzheimer's type) by antihypertensive treatments. In this context, the effect of antihypertensive treatment on cognitive functions should represent one of the primary criteria of assessment in future morbidity and mortality studies in hypertensive patients.

[Cognitive decline and hypertension]. / Déclin cognitif et hypertension artérielle.

The prevalence and incidence of degenerative and vascular dementia increase exponentially with age. Several studies in recent years have implicated hypertension as a risk factor not only for vascular dementia but also for degenerative dementia such as Alzheimer's disease. This is an important finding because it suggests that the treatment of hypertension could reduce the incidence of dementia. In particular, the results of the Syst-Eur study, showing that a calcium inhibitor, nitrendipine, could reduce not only the incidence of stroke but also that of dementia, should be confirmed.

[Relationship between arterial pressure and cognitive functions. Data for the French Network on Alzheimer's disease (REAL.FR)]. / Relations entre la pression artérielle et les fonctions cognitives. Données du Réseau français sur la maladie d'Alzheimer (REAL.FR).

UNLABELLED: The relationships between arterial hypertension and cognitive decline are complex and studies indicate controversial results. OBJECTIVES: To evaluate, in a cross sectional study, the relationships between cognitive functions and blood pressure in a population of subjects with Alzheimer's disease. METHODS: In 520 subjects of a survey in a French population with Alzheimer's disease, relationships between the severity of cognitive decline and a history of hypertension or blood pressure level have been searched. Cognitive functioning was assessed with validated neuropsychological tests evaluating cognitive functions and the capacities in the activities of daily living (Mini Mental State Examination (MMSE), Alzheimer's Disease Assessment Scale--Cognitive part (ADAS-Cog), Instrumental Activities of Daily Living (IADL), Activities of Daily Living (ADL), Clinical Dementia Rating (CDR), Global Deterioration Scale (GDS) of Reisberg). In 456 subjects blood pressure was measured during the consultation. RESULTS: The results indicate that after adjustment on age, sex, education level, and the other cardiovascular risk factors, subjects with a history of hypertension have a more marked cognitive decline than subjects without history of hypertension. Indeed, in subjects with a history of hypertension, the cognitive impairment and its consequences on activities of daily living are more important than in subjects without history of hypertension (ADAS-cog 19.02 +/- 8.48 vs 17.49 +/- 8.53 p = 0.06, MMSE 19.55 +/- 4.41 vs 20.30 +/- 4.42, p = 0.08, score ADL 5.31 +/- 0.86 vs 5.51 +/- 0.87, p = 0.01, CDR 6.94 +/- 3.29 vs 6.19 +/- 3.26 p = 0.03; global CDR 1.18 +/- 0.62 vs 1.05 +/- 0.60, p = 0.03, GDS of Reisberg 4.41 +/- 0.74 vs 4.27 +/- 0.75, p = 0.05). In contrast, no relation between blood pressure measurements and cognitive function is observed, and moreover an inverse correlation between blood pressure and consequences on activities of daily living is found. CONCLUSIONS: This work indicates that relationships between blood pressure and cognitive functions are more complex than a simple linear relation. The present results show that a history of arterial hypertension is associated with a more marked cognitive decline in subjects with Alzheimer's disease. In contrast, when the Alzheimer's disease is already developed no relation between blood pressure and cognitive functions appears and moreover an inverse correlation with the consequences on activities of daily living is found.

Association of the apolipoprotein E epsilon4 allele with late-onset depression.

Apolipoprotein E (ApoE) phenotyping was determined in 42 subjects with Alzheimer's disease (AD), 49 with depression, including 26 with early-onset depression (EOD) and 23 with late-onset depression (LOD), and 49 controls. In the EOD group, the frequency of the ApoE epsilon4 allele was not different from the control frequency (p = 0.532) but was significantly lower than in AD (p < 0.001). In the LOD group, the ApoE epsilon4 frequency was significantly higher than in the controls (p = 0.034) but was not different from that in the AD group (p = 0.229). Individuals with ApoE epsilon4 were at greater risk of getting AD (odds ratio, OR = 5.5, 95% confidence interval, CI, 2.0-14.0) or LOD (OR = 6.1, 95% CI, 1.9-19.0) than of EOD (OR = 0.7, 95% CI, 0.2-2.5). These results suggest an association between the ApoE epsilon4 allele frequency and LOD. Patients with LOD could be at risk of developing AD by an epsilon4-dependent pathway.

Does vascular endothelial growth factor in the rheumatoid synovium predict joint destruction? A clinical, radiological, and pathological study in 12 patients monitored for 10 years.

OBJECTIVE: Synovial angiogenesis is at the epicenter of rheumatoid pannus development and is largely dependent on vascular endothelial growth factor (VEGF). We sought to determine whether the VEGF level in rheumatoid synovial tissue is a marker for disease severity. PATIENTS AND METHODS: Twelve patients with rheumatoid arthritis (RA) underwent a clinical and radiological evaluation at the time of a synovial biopsy done during joint surgery required by RA progression (T1) and, on average, 10 years later (T2). Immunohistochemistry was used to detect and quantitate VEGF in the synovial biopsy taken at T1. RESULTS: VEGF labeling was seen on endothelial cells and macrophages in all 12 synovial biopsies. The amount of endothelial-cell VEGF labeling (assessed semi-quantitatively) was significantly correlated with Larsen score progression during the 10-year follow-up. The amounts of endothelial cell or macrophage VEGF labeling was not correlated with the joint count, radiological stage of the biopsied joint or progression of this stage, Larsen scores at T1 or T2, presence of rheumatoid factor, or presence of extra-articular manifestations. CONCLUSION: Our results suggest that the amount of VEGF in the rheumatoid synovium may be a marker for joint destruction in patients with RA.

The apolipoprotein E epsilon4 allele and the response to tacrine therapy in Alzheimer's disease.

The objective of our study was to evaluate the effects of the apolipoprotein E (ApoE) phenotype and gender on the response to tacrine treatment in Alzheimer's disease (AD). ApoE phenotyping was performed on 76 patients treated with tacrine for AD. This group comprised 33 ApoE epsilon4 allele carriers (epsilon4+) and 43 non-epsilon4 carriers (epsilon4-). Patients were treated blindly in relation to the ApoE phenotype, with incremental tacrine dosages ranging from 40 mg/day up to the highest dosage (160 mg) tolerated without side-effects. At least 6 weeks elapsed between each increase. Changes in the scores for the Alzheimer Disease Assessment Scale-Cognitive Component (ADAS-Cog) between baseline and each increment in dosage were assessed in the epsilon4- and epsilon4+ groups. The cut-off point for being considered as responsive to tacrine treatment was a 4-point decrease in the ADAS-Cog score. There was no tendency for the epsilon4- carriers to respond better than the epsilon4+ carriers. When patients were stratified by gender, no differences were found between the effects of the treatment on men and women. Consequently, these results do not support the hypothesis that the ApoE phenotype and gender are predictors of the response to tacrine in AD patients.

Dehydroepiandrosterone (DHEA), DHEA sulfate, and aging: contribution of the DHEAge Study to a sociobiomedical issue.

The secretion and the blood levels of the adrenal steroid dehydroepiandrosterone (DHEA) and its sulfate ester (DHEAS) decrease profoundly with age, and the question is posed whether administration of the steroid to compensate for the decline counteracts defects associated with aging. The commercial availability of DHEA outside the regular pharmaceutical-medical network in the United States creates a real public health problem that may be resolved only by appropriate long-term clinical trials in elderly men and women. Two hundred and eighty healthy individuals (women and men 60-79 years old) were given DHEA, 50 mg, or placebo, orally, daily for a year in a double-blind, placebo-controlled study. No potentially harmful accumulation of DHEAS and active steroids was recorded. Besides the reestablishment of a "young" concentration of DHEAS, a small increase of testosterone and estradiol was noted, particularly in women, and may be involved in the significantly demonstrated physiological-clinical manifestations here reported. Bone turnover improved selectively in women >70 years old, as assessed by the dual-energy x-ray absorptiometry (DEXA) technique and the decrease of osteoclastic activity. A significant increase in most libido parameters was also found in these older women. Improvement of the skin status was observed, particularly in women, in terms of hydration, epidermal thickness, sebum production, and pigmentation. A number of biological indices confirmed the lack of harmful consequences of this 50 mg/day DHEA administration over one year, also indicating that this kind of replacement therapy normalized some effects of aging, but does not create "supermen/women" (doping).

Detection of cerebral aging, an absolute need: predictive value of cognitive status.

Cognitive performance is predictive of functional status, morbidity and mortality in the elderly. In the SYST-EUR study, the Vascular Dementia Project run on 3,111 subjects 60 years old and over, with isolated systolic hypertension, has shown that the cognitive status as measured by the MMSE was inversely correlated with systolic blood pressure (p < 0.001) and age (p < 0.001) and positively correlated with the level of education (p < 0.001). It is significantly lower in patients with cardiovascular complications (p = 0.0001). Moderate alcohol consumption is linked to a higher MMSE score in women (p < 0.001) but not in men. In this study, the incidence of dementia is low and significantly related to the baseline value of the MMSE score and further analysis will show the influence of the treatment of systolic hypertension with calcium antagonists as first step on this incidence.

[Rotablator and endoprosthesis on the left main coronary trunk]. / Rotablator et endoprothèse sur tronc commun de la coronaire gauche.

A 78 year old woman with unstable angina due to significant stenosis of the left main coronary artery and occlusion of the right coronary artery was treated medically for 29 months because of a surgical contraindication. Resistance to drug therapy led to referral for complex angioplasty of the left main, left anterior descending and left circumflex arteries, successively by rotablator and balloon angioplasty. An immediate elastic recoil on the left main coronary artery led to implantation of a Palma-Schatz stent. There were no complications and the patient is asymptomatic twenty months later.

[Thromboembolic disease in patients aged 80 and over. Diagnostic and therapeutic strategies]. / La maladie thromboembolique chez la personne âgée de 80 ans et plus. Stratégies diagnostiques et thérpeutiques.

The aim of this retrospective study of 50 deep vein thromboses (DVT) of the lower limbs in patients aged 80 and over (35 women, including 2 with bilateral DVT and 13 men), mean age 83.37 +/- 2.72, hospitalised in a department of cardiology, was to assess the diagnostic value of ultrasound investigations, clinical parameters and results of treatment of thrombo-embolic disease in this age group. High DVT were found in 76 per cent of cases and pulmonary embolism occurred in 52.1 per cent of cases, its incidence increasing with age. One third of DVT were asymptomatic and presented as pulmonary embolism, the predominant clinical feature being edema in the absence of other signs. The existence of atrial fibrillation was associated in 90 per cent of cases with a pulmonary embolism. Venous Echo-Doppler is also the key investigation in the diagnosis of thrombo-embolic disease. Cardiac Echo-Doppler seems particularly useful in the diagnosis of pulmonary embolism when more than 40 per cent of the vascular bed is cut off. Thrombolytic treatment remains possible after the age of 80 in life-threatening situations. Overall hospital mortality remains high (10.4 per cent) and appears to be due chiefly to the onset of a pulmonary embolism which is not thrombolyzed since considered insufficiently serious or occurring in a situation in which fibrinolysis is theoretically contra-indicated.

[Spontaneous dissection of the distal anterior interventricular artery during intravenous thrombolysis]. / Dissection spontanée de l'artère interventriculaire antérieure distale observée au décours d'une thrombolyse intraveineuse.

A case is reported of spontaneous coronary dissection in a 55-year-old patient with an anterior myocardial infarction treated by intravenous thrombolysis. The angiographic appearance was highly characteristic with successive opacification of the true then the false channel involving the entire distal third of the anterior interventricular artery. The outcome was immediately favourable. Spontaneous dissection of coronary arteries is rare. The etiology is discussed and there is not standard management approach.

[Apical hypertrophic pseudocardiomyopathy: nosological problems]. / Pseudo-cardiomyopathie hypertrophique apicale: problèmes nosologiques.

The classification of hypertrophic cardiomyopathies remains a thorny nosological problem. Within this extensive diagnostic group, it is felt that the very special sub-group of "Japanese" apical hypertrophic forms must be subject to the strictest possible criteria in order to avoid improper use. The case reported here of biventricular apical hypertrophic cardiomyopathy in a 60-year-old woman with a family history of HCM, in whom the clinical, ECG and above all angiographic features were typically those of AHCM but where the existence of an intraventricular gradient was found during challenge manoeuvres emphasises this classification problem. Pseudo-AHCM in a context of OCM or pseudo-OCM in a context of AHCM? The discussion is not merely of nosological interest in view of the recently documented clear prognostic differences between these two conditions. Main series from the literature are reviewed.

[Treatment of urogenital prolapse with exertion-induced urinary incontinence using the Bologna technic. Apropos of 90 cases]. / Traitement des prolapsus uro-génitaux avec incontinence urinaire d'effort par l'intervention de Bologna. A propos de 90 cas.

The authors describe this operation, which is carried out as a single procedure which they have been doing since 1982. Then the results in 90 patients are studied. The post-operative controls carried out on the clinical state of the patient and on the urodynamic tests show that this operation is very successful, both in curing stress incontinence and in giving a good anatomical result for correcting prolapse of the anterior wall of the vagina. In over one-third of the cases the post-operative follow-up has been carried out for 2 years or more. This follow-up has shown that the relapse rate over a period of time, both for the stress incontinence and the prolapse, is nil. The principal snags that still remain are: post-operative infection in about a third of cases; the rare but possible development of an enterocele and of dyspareunia (2%).

MR imaging of anterior sacral meningocele.

The magnetic resonance appearance of a case of an anterior sacral meningocele is described and the particular advantages of this technique, compared with other radiological studies, are considered.

Myelolipoma arising from ectopic adrenal cortex: case report and review of the literature.

A myelolipoma was surgically removed following its identification by computed tomography scan. The presenting symptom was abdominal pain, associated with an enlarging mass in the lower abdomen. Histological review found the myelolipoma to be arising from ectopic adrenocortical tissue. Myelolipomas arising from extra-adrenal locations are rare. The literature was reviewed and various presentations of this benign tumor were discussed.
