ABSTRACT

BACKGROUND AND PURPOSE: The differential diagnosis of acute cervical pain includes nonvascular and vascular causes such as carotid dissection, carotid occlusion, or vasculitis. However, some patients present with unclassified vascular and perivascular changes on imaging previously reported as carotidynia. The aim of our study was to improve the description of this as yet unclassified clinico-radiologic entity. MATERIALS AND METHODS: From January 2009 through April 2016, 47 patients from 10 centers presenting with acute neck pain or tenderness and at least 1 cervical image showing unclassified carotid abnormalities were included. We conducted a systematic, retrospective study of their medical charts and diagnostic and follow-up imaging. Two neuroradiologists independently analyzed the blinded image datasets. RESULTS: The median patient age was 48 years. All patients presented with acute neck pain, and 8 presented with transient neurologic symptoms. Imaging showed an eccentric pericarotidian infiltration in all patients. An intimal soft plaque was noted in 16 patients, and a mild luminal narrowing was noted in 16 patients. Interreader reproducibility was excellent. All patients had complete pain resolution within a median of 13 days. At 3-month follow-up, imaging showed complete disappearance of vascular abnormalities in 8 patients, and a marked decrease in all others. CONCLUSIONS: Our study improved the description of an unclassified, clinico-radiologic entity, which could be described by the proposed acronym: TransIent Perivascular Inflammation of the Carotid artery (TIPIC) syndrome.

ABSTRACT

UNLABELLED: Data registration by the GROG national network (Regional Group for the Surveillance of Influenza) since 1984 has helped to identify methodological problems. The choice of sentinels and the selection of indicators depend on the analysis of actual influenza consequences. Various sentinels may be concerned: health insurance companies, private companies, schools, physicians, pharmacists. Health care organization modifies the validity of indicators. In France, for instance, home visits were an excellent indicator for early warning before 1995 but this indicator is no longer as efficient as before. The virological detection of Influenza depends on the organization of transportation (samples, results). The predictive value of cases definitions depends on the incidence of infection. The level of choice between specificity and sensibility modifies the perception of outbreaks. Sentinel participation rate influences the sample representativity. The farther this rate is from 100%, the more result validity decreases (in the same way that patients lost to follow-up compromise the validity of results in clinical trials). The publication of results can modify health expenses and behaviors. CONCLUSION: The GROG network stresses the important role that general practitioners play in health surveillance; it also raises questions in the field of mathematics, statistics, professional organization, training, education, and politics.

ABSTRACT

BACKGROUND: In the BIGPRO 1 trial, one year of treatment with metformin in non-diabetic obese subjects with a central fat distribution had no significant effect on fasting plasma triglyceride concentration or on blood pressure despite a decrease in weight, fasting plasma insulin and glucose concentrations. To re-evaluate the effect of metformin on fasting triglyceride concentration and on blood pressure, the BIGPRO 1.2 trial included non-diabetic men (n=168) with a fasting plasma triglyceride concentration > or =1.7 and < or =6.5 mmol/l, high blood pressure (systolic > or =140 and < or =180 and/or diastolic > or =90 and < or =105 mmHg, or treatment for hypertension) and a waist-to-hip ratio > or =0.95. METHODS: A randomised double-blind trial comparing metformin treatment (850 mg bid) with placebo. RESULTS: Metformin had no significant effect either on blood pressure or plasma triglyceride concentration. In comparison with the placebo group, fasting plasma insulin (p<0.04), total cholesterol (p<0.05) and Apo B (p<0.008) concentrations decreased more in the metformin group in the BIGPRO 1. 2 trial, confirming most of the previous results of the BIGPRO 1 trial. Tissue plasminogen activator antigen concentration decreased significantly (p<0.01) only in the metformin group, but this was not significantly different from the placebo group (p<0.12); further, there were no significant differences in the change in plasminogen activator inhibitor 1. CONCLUSIONS: The consistency of the two BIGPRO trials supports the conclusion that metformin affects several cardiovascular risk factors favourably in non-diabetic subjects with a central fat distribution.

ABSTRACT

Due to its vascular and platelet 5-HT2 receptor antagonist properties and its metabolic properties, naftidrofuryl specifically counteracts local ischaemic phenomena. One of its major indications is the treatment of intermittent claudication, but it is well known that peripheral arterial disease is the sign of diffuse arterial disease, associated with particularly lethal coronary disease. Recent studies increasingly implicate serotonin (5-HT) in coronary ischaemic processes. In view of the similarities between these pathophysiological data and the characteristics of this molecule, we decide to evaluate the coronary protection afforded by naftidrofuryl and its safety. This multicentre double-blind placebo-controlled study was conducted in 51 patients over a period of one month. Inclusion criteria were stable angina with an electrically positive stress test, despite antianginal treatment either by beta-blocker or by calcium channel blocker. Follow-up comprised clinical assessment and a stress test on inclusion and at 1 month. The groups were comparable on inclusion. Overall, the results showed a greater improvement with naftidrofuryl than with reference treatment for all parameters studied. Significant differences were observed in favour of the verum group for time to onset of ST depression, the maximum level reached, the number of stress tests which became negative and the patient's global assessment. No problems of interaction with concomitant treatments, particularly beta-blockers, calcium channel blockers or antiarrhythmics was observed. This study shows that naftidrofuryl allows improvement of ergometric parameters and especially elevation of the ischaemic threshold on exertion.

ABSTRACT

Tissue hypoxaemia can be evaluated by the noninvasive method of transcutaneous oxygen tension (tcpO2) measurement in patients with peripheral arterial occlusive disease (PAOD). The effects of naftidrofuryl (Praxilene) on exercise-induced tissue ischaemia was objectively assessed by continuously measuring the tcpO2 in 30 patients during three treadmill tests over a 3-month period in a randomized double-blind, placebo controlled, parallel group study. To be included in the study, the tcpO2 and total walking distance had to be stable during the washout period (D-15-D0). The area under the tcpO2 curves was scanned and automatically calculated after identification of baseline and the end of the treadmill test. The treadmill test on D30 and D90 was terminated at a similar walking distance to that obtained on D0. On D0 both groups were comparable (p = 0.22). The area under the curve (AUC) reduced significantly in the naftidrofuryl group between D0 and D30 (p < 0.001) and D0 and D90 (p < 0.001). However, no significant tcpO2 AUC reduction was found in the placebo group (D0-D30, p = 0.58; D0-D90, p = 0.50). This was confirmed by calculation of the percentage of patients whose percentage change in the AUC on D90 was higher than the upper limit of the 90% confidence interval, calculated from the percentage change over the washout period. Of the 15 patients receiving natfidrofuryl, 66.6% exceeded this upper limit, compared with only 7% of patients receiving placebo (p = 0.0017). This study shows that naftidrofuryl has a protective effect on exercise-induced tissue ischaemia as measured by the tcpO2 AUC in PAOD stage II patients.

ABSTRACT

The authors observed 66 cases of peripheral facial palsy (PFP) in children during a 5-year period (1986-1990). Bell's palsy (idiopathic facial paralysis) occurred in 26 children (39.3%), 1 month to 14.5 years old, with a complete recovery in 95% of the cases; a surgical decompression was carried out in 2 cases. The PFP was related to otitis in 16 cases (24.2%): acute otitis media (6), mastitis (4), serous otitis (5), cholesteatoma (1); the treatment was medical and surgical in all cases with complete recovery in 15 cases. In 15 cases the PFP was secondary to trauma (13) or surgery (2); complete spontaneous recovery occurred in 11 cases, and partial recovery following surgical treatment in 2 cases. A viral origin was retained in 6 cases: herpes zoster (3), mumps (1), echovirus (1), herpes (1); the recovery was complete in 4 cases, partial in 2 cases. In 3 cases the PFP was related to a rare cause: lymphoma, metabolic acidosis, Melkerson-Rosenthal syndrome. Bell's palsy remains the main cause of PFP in childhood; other etiologies can be ruled out by the case history, a careful physical examination, and a limited number of laboratory and/or X-ray studies; medical treatment, in particular prednisone, does not seem to have an effect upon the rate of recovery which is spontaneously high; similarly there is no evidence that surgical decompression really modifies the rate of recovery so that the authors suggest that it should be reserved to the complete forms with no clinical and electrical evidence of recovery after 3 weeks.
