RESUMO
MEEREB is an inter-regional network of countries from North Africa, Europe, the Middle East and Central Asia that work together with the aim of improving rabies control and prevention at local, regional and global level. MEEREB members met for the third time in 2015 in France (Lyon) to review the current rabies situation within the network and to discuss the way forward the prospect of a One Health approach against rabies. Dogs were the main vector of transmission in all MEEREB countries except for Croatia and Serbia where foxes represented the primary source. The number of rabies animal cases reported in 2014 varied substantially between countries with Ukraine reporting the highest number of animal cases. Human cases still occur in North Africa and all Middle East and Eurasian countries while no cases of human rabies were reported in Croatia, Serbia and Romania, although cases of rabies were identified in both dogs and foxes in 2014. Participants concluded that MEEREB can act as a think-tank where countries can share data, information, experiences and best practices to jointly address challenges in rabies control and prevention. They called for elimination of dog-transmitted rabies through vaccine and rabies immunoglobulin stockpiles and implementation of a One Health approach to achieve rabies's eradication.

The authors report a very rare case of massive haemolytic anaemia complicated by renal failure in a patient with a double aortic and mitral bioprosthesis. The haemolysis was attributed to degeneration of the aortic bioprosthesis causing turbulent flow, aggravated by associated infectious endocarditis. The essential condition for haemolysis is a change in blood flow through the valve by degeneration or other associated pathology. The haemolytic anaemia completely regressed after aortic valve replacement as did the renal failure.

Our actual work studies the effectiveness in vivo of the Benzathin penicillin that is realized on 88 subjects suffering from a stable rheumatic fever. It has shown that: The first hours after an intramuscular injection, the benzathin penicillin is found at an efficient concentration superior to 0.02 ug/ml at the level of the blood. The highest dose in the blood is obtained the first 24 hours. The amount of antibiotic at the level of the blood is very efficient during 4 weeks.

We have analysed 302 bp of the first hypervariable region of the mitochondrial D-loop in 271 individuals from different regions of the Iberian Peninsula and 85 individuals from Algeria. The Basque population is significantly different from neighbouring populations in terms of overall levels of diversity. This is because the majority of sequences in the Basques are restricted to the lineage group defined by the CRS (Cambridge Reference Sequence) and its derivatives although, like other Iberian populations, they showed a unimodal distribution of pairwise sequence differences. The timing of divergence of populations within Iberia points to a shared ancestry of all populations in the Upper Palaeolithic. Further genetic subdivision is apparent in Catalonia and Andalusia, with increased genetic diversity in the latter. Lineage diversity comparisons of Iberian populations with European (Tuscan) and North African (Algerian) populations shows the Iberian Peninsula to be more similar to other European populations, although a small number of Iberian lineages can be traced to North Africa.

The haemodynamic data of 1,189 subjects with an atrial septal defect catheterised between 1953 and 1983 at the Marie Lannelongue Surgical Center and at Broussais Hospital was reviewed. Sixty per cent were under 20 years of age and 40 per cent were 21 to 75 years of age. The defect was an ostium secundum type in 89 per cent and sinus venosus in 11 per cent of patients. The commonest associated cardiac malformation was a partial anomalous pulmonary venous drainage which was present in 125 patients. Systolic and mean pulmonary arterial pressures decreased from a value slightly higher than normal between birth and 5 years of age to normal values between 5 and 20 years of age and then increased progressively to maximal values attained after 50 years of age (p less than 0.001). The proportion of patients with raised systolic and mean pulmonary arterial pressures increased with age after 20 years of age (p less than 0.001). A parallel increase in pulmonary blood flow was observed after 20 years of age, which was less marked than the increase in pressures, but nevertheless statistically significant (p less than 0.05). This increase in left to right shunt disappeared after 50 years of age. An increase in pulmonary resistances was observed after 20 years of age and persisted all through life (p less than 0.001). Two successive preoperative catheter studies were performed in 34 patients after a 6.4 +/- 4.7 years interval. In each patient, systolic pulmonary arterial pressures had increased and were significantly higher at the time of the second study (p less than 0.001).(ABSTRACT TRUNCATED AT 250 WORDS)

2 cases of severe pulmonary valvular stenosis in two young adults aged 21 and 29 years respectively are presented. Despite the degree of stenosis (4 mm jet), the right ventricular pressures did not exceed systemic pressures because of severe tricuspid regurgitation. This dominated the clinical and anatomical findings, causing aneurysmal dilatation of the right atrium and displacement of the tricuspid valve to the left. The diagnosis of Ebstein's anomaly was raised in one case but excluded by echocardiography and angiocardiography. In spite of the severity of the symptoms and peripheral clinical signs, surgery of the right ventricular outflow tract, tricuspid valvuloplasty and resection of part of the right atrium led to a complete and rapid cure, confirmed by catheterisation one month after operation.

The M mode echocardiographic recordings of 52 normal mitral bioprostheses (NMB), 7 pathological mitral bioprostheses (PMB), 30 normal aortic bioprostheses (NAB) and 10 pathological aortic bioprostheses (PAB) were reviewed. In normal bioprostheses a significant correlation was observed between the echocardiographic and the "specified" diameters, the diastolic and systolic slopes and the amplitude of anterior motion of the support. In NMB, the end-systolic diameter of the left ventricular outflow tract depended on the "specified" diameter of the bioprosthesis. Paradoxical septal motion was observed in 78 p. 100 of cases. In PMB, the velocity of anterior leaflet opening was significantly increased (p less than 0.001). The end-diastolic internal left ventricular dimension was also increased (p less than 0.01). A significant correlation was found between left ventricular fractional shortening and maximal leaflet separation (p less than 0.05). Normal septal motion was more common (p less than 0.05). In 5 cases of prosthetic valve dysfunction with mitral regurgitation the maximal leaflet separation was greater than normal (p less than 0.001), the diastolic slope of the support was increased (p less than 0.05) and diastolic vibrations of thickened irregular leaflets were observed. Systolo-diastolic vibrations with chaotic leaflet motion were characteristic of cusp tear and/or eversion. Stratified echos behind a support with reduced leaflet excursion was observed in one case of partial thrombosis: a thickened systolic echo with reduced diastolic excursion was observed in a case of degenerative stenosis. The review of 10 PAB showed a reduced amplitude of systolic excursion of the anterior support in cases of aortic regurgitation (p less than 0.05). Systolic vibrations of the cusp were not specific and were observed in normal cases. In severe valvular regurgitation mitral and/or septal diastolic fluttering was observed. Systolic excursion of the cusps was reduced in cases of relative stenosis due to an inappropriately small sized bioprosthesis. Thickening of the diastolic cusp echos was observed in cases of degenerative stenosis. Ventricular dilatation and reduced septal and free wall motion were dysfunction.

Reactional infundibular hypertrophy in pulmonary valve stenosis is usually assessed on the catheterization curves obtained in the infundibulum and in the inflow tract of the right ventricle. It is usually indicated by a peculiar pattern of the infundibular curve: its descending branch is more rapid than in the inflow tract and is slightly curvilinear. This deformity is the more marked the more intense the hypertrophy. Simultaneously a mid-late systolic murmur is recorded into the infundibulum the more intense and high-pitched the more marked the hypertrophy. Comparison with the angiocardiographic data and the operative findings showed a good correlation.
