[Exploring the effects of entecavir treatment on the degree of liver fibrosis in patients with non-alcoholic fatty liver combined with chronic hepatitis B in Tibet region].

Objective: To explore the efficacy of entecavir antiviral therapy on the degree of liver fibrosis in patients with non-alcoholic fatty liver disease (NAFLD) combined with chronic hepatitis B (CHB) in Tibet region. Methods: HBeAg-positive CHB patients who were treated with entecavir in the outpatient and inpatient Department of Infectious Diseases of the Tibet Autonomous Region people's Hospital between January 2018 to December 2019 were retrospectively analyzed. Among the 140 subjects with CHB, 95 cases were CHB alone, and the other 45 cases were diagnosed as CHB combined with NAFLD by ultrasound. All patients were given entecavir 0.5 mg orally once daily on an empty stomach for 48 weeks. HBeAg negative conversion rate, blood glucose, blood lipid, liver function and the degree of liver fibrosis were compared between the two groups at the 12th, 24th and 48th weeks of treatment to evaluate the virological response. SPSS 19.0 statistical software was used to process the data. Measurement data were expressed as mean ± standard deviation (x¯±s). Descriptive statistical analysis was used for t-test, and the categorical variables were expressed as percentage (%) and χ2 test. A p-value < 0.05 was considered as statistically significant. Results: After 48 weeks of treatment, the HBeAg and HBV DNA negative conversion rate were significantly better in patients with CHB alone (group B) than CHB combined with NAFLD (group A), that is to say, HBeAg negative conversion rate in group A and B patients were 28.90% and 40%, respectively, and group B was better than group A. HBV DNA negative conversion rate was significantly elevated in group B (83.2%) than group A (64.4%), with statistical significance (P<0.05), and the difference between the both groups was statistically significant. Alanine aminotransferase level was significantly decreased in patients with CHB alone than patients with CHB combined with NAFLD. Aspartate aminotransferase/platelet ratio index was significantly decreased after treatment than before treatment in both group of patients, and the depletion was more pronounced in CHB alone group. Liver stiffness values were significantly decreased in patients with CHB combined with NAFLD than CHB alone group. Moreover, liver stiffness values was higher in group A than group B before treatment under the influence of fat attenuation factors, and the differences before treatment and after treatment were 3.50±4.66 and 2.05±2.53, respectively; however, group B was not affected by fat attenuation factors, so LSM value reduction in group A was more obvious, and the differences were statistically significant. There was no statistically significant difference in blood glucose and blood lipids levels before and after treatment between the two groups. Conclusion: NAFLD has a certain effect on antiviral therapy and liver fibrosis in patients with CHB, i.e., the effect of antiviral therapy in patients with CHB alone is better than patients with CHB combined with NAFLD. Patients with CHB combined with NAFLD when treated with antiviral therapy had a significantly greater degree of liver stiffness reduction than patients with CHB alone. Therefore, it is necessary to actively intervene the risk factors associated with NAFLD according to the actual situation of different individuals to improve clinical efficacy of antiviral therapy.

[Schoolchildren's visual acuity in the dynamics of learning].

The results of the screening study of the acuity of schoolchildren between 7 and 17 years old living in Rostov Region of the Russian Federation are discussed in the article. The method of computer optometry was used to measure acuity. 93772 pupils, 48621 girls and 45151 boys, from 150 schools participated in this examination. It was found that there is sustained growth of those with low acuity (0,2 and less) among children of both sexes from junior group (7 years) to the senior (17). The signs of the decline in visual acuity among girls (14%) are manifested earlier than in boys (8%). The decline in visual acuity among 7-8-year-old children is about 3%. While comparing children from rural areas with those from big cities a true dependence of the parameter (acuity) on the factors (city and sex) was found.

Rare cases of limb ischemia indicative of HIV infection have been described.We report a case of venous thrombosis of the left lower limb and bilateral lower arterial ischemia revealing an HIV infection in a patient of 44 years. The CD4 count was 195/mm(3). Investigations on coagulation were not realized. The patient was amputated both his legs.

[Research advances on thymosin ß4 in promoting wound healing].

With the aging of population and the development of social economy, the incidence of chronic wounds is increasing day by day, while the incidence of burns and trauma remains at a high level, making wound repair an increasingly concerned area in clinical practice. Thymosin ß4 is a naturally occurring small molecule protein in vivo, which is widely distributed in a variety of body fluids and cells, especially in platelets. Thymosin ß4 has biological activities of promoting angiogenesis, anti-inflammation, anti-apoptosis, and anti-fibrosis, and has many important functions in wound repair. Thymosin ß4 has been observed to promote the healing of various wounds, such as burns, diabetic ulcers, pressure ulcers. This paper will review the molecular structure, mechanism of wound healing promotion, pharmacokinetics, and clinical application of thymosin ß4, aiming to introduce its potential in wound treatment and the shortcomings of current researches.

[Epidemiological, clinical and ultrasonographic aspects of right-sided infective endocarditis in Senegal: 6 cases]. / Aspects epidémiologiques, cliniques et echographiques des endocardites infectieuses du coeur droit au Sénégal: 6 observations.

Right-sided infective endocarditis accounts for 5 to 10% of endocarditic involvement and usually affects the tricuspid valve. The purpose of this report is to describe epidemiological, clinical and echocardiographical aspects of 6 cases of right-sided infective endocarditis observed in the Cardiology Department of Aristide Le Dantec Hospital in Dakar, Senegal from December 2007 to February 2010. Diagnosis was based on Duke's modified criteria. There were 3 men and 3 women with a mean age of 28.2 years (range: 20 and 43). Five of the 6 patients presented tricuspid endocarditis including one case associated with pulmonary endocarditis. In another case, pulmonary endocarditis was associated with aortic endocarditis. Infective endocarditis was acute in three cases and primary in four. One case of infective endocarditis was observed in a tetralogy of Fallot. Fever was present in 4 cases with an mean temperature of 38.4 degrees C (range, 37.2 to 40 degrees C) and heart failure was present in 5 cases. In 2 patients, blood cultures were positive for Staphylococcus aureus. All patients had leucocytosis with a neutrophilic predominance. Doppler echocardiography depicted vegetations in all cases. Contributing factors included congenital heart disease in 1 case, insertion of a venous catheter in 2 and dental infection in 2. No patient was addicted to intravenous drugs or infected by HIV. Outcomes included one in-hospital death with signs of refractory heart failure. Right-sided endocarditis is often primary and is dominated by the tricuspid involvement. It affects both sexes. Contributing factors include venous catheterization during the postpartum period and dental infection. Prevention requires strict asepsis during venous catheter insertion, treatment of dental infections and improved management of congenital heart disease.

[Performance of magnetic resonance imaging ang genourob laximetry in anterior cruciate ligament rupture in 30 cases]. / Performance de l'imagerie par resonance magnetique et de la laximetrie a genourob dans les ruptures du ligament croise anterieur a propos de 30 cas.

INTRODUCTION: The aim of this work was to evaluate the diagnostic contribution of magnetic resonance imaging and genourob compared to intraoperative arthroscopy. The objective was to implement a protocol based on magnetic resonance imaging and / or genourob. MATERIALS AND METHODS: We did a cross-sectional study from July 18, 2016 to July 19, 2017 at the Maltese hospital comparing the results of MRI and GNRB from 30 patients compared to intraoperative arthroscopy data. RESULTS: Complete break.- In MRI, we obtained a sensitivity (Se) of 95.7%, a specificity (Sp) of 85.7%.- At the GNRB, we found a Se of 87%, a Sp of 42.9%.Partially broken.- In MRI we obtained a Se of 85.7%, a Sp of 95.7%.- At the GNRB, we found a Se of 42.9%, a Sp of 87%. CONCLUSION: MRI is better than GNRB. The GNRB does not improve the results of the MRI. It has no diagnostic contribution in the rupture of the ACL knee. It is a device used by the orthopedists to evaluate knee laxity that does not depend on the ACL alone.

INTRODUCTION: Le but de ce travail était d'évaluer l'apport diagnostique de l'imagerie par résonance magnétique (IRM) et du genourob (GNRB) par rapport à l'arthroscopie per opératoire. L'objectif était de mettre en place un protocole basé sur l'IRM et / ou le GNRB. MATÉRIELS ET MÉTHODES: Nous avons fait une étude transversale allant du 18 Juillet 2016 au 19 juillet 2017au centre hospitalier de l'ordre de malte en comparant les résultats d'IRM et du GNRB de 30 patients par rapport aux données de l'arthroscopie per opératoire. RÉSULTATS: ✓ Rupture complète.- En IRM, nous avons obtenu une sensibilité (Se) de 95,7 %, une spécificité(Sp) de 85,7%.- Au GNRB, nous avons trouvé une Se de 87 %, une Sp de 42,9%.✓ Rupture partielle.- En IRM, nous avons obtenu une Se de 85,7 %, une Spde 95,7%.- Au GNRB, nous avons trouvé uneSe de 42,9 %, une Sp de 87%. CONCLUSION: L'IRM est plus performante que le GNRB. Le GNRB ne permet pas d'améliorer les résultats de l'IRM. Il n'a pas d'apport diagnostique dans la rupture du LCA du genou. C'est un dispositif utilisé par les orthopédistes pour évaluer une laxité du genou qui ne dépend pas du LCA à lui seul.

[Management of orbital inflammatory disorders in internal medicine: New findings resulting from a retrospective study of 31 consecutive patients]. / Prise en charge des orbitopathies inflammatoires en médecine interne : nouvelles données issues de l'étude d'une série de 31 patients consécutifs.

PURPOSE: To describe a case series of patients investigated in internal medicine for orbital inflammation (OI) since the individualization of the clinical entity of the IgG4-related orbital disease (IgG4 ROD). PATIENTS AND METHODS: Thirty four patients were consecutively referred by a specialized center where orbital biopsy was performed when the lesion was surgically accessible. Fourteen patients were excluded in case of missing data or lymphoma, periocular xanthogranuloma or Graves' orbitopathy. Patients with systemic or auto-immune disease according to the international criteria, or presenting with idiopathic orbital inflammation syndrome (IOIS), were included. Knowing the histological similarities between IOIS and IgG4 ROD, immunohistochemical assessment of plasma cells for IgG4 positivity was performed for every patient with available biopsy. Clinical and biological characteristics, treatment and response to treatment of included patients are reported. RESULTS: Among 22 included patients, 10 presented with orbital manifestation of a systemic or autoimmune disease including 2 sarcoidosis (9%) and 8 (36%) cases of non specific OI which were reclassified in IgG4 ROD. Finally, IOIS of various clinicopathological presentation was diagnosed for 12 patients including 10 with histological documentation. Whereas relapse and resistance were not found to be related to IgG4 positivity (50% in both IOIS and IgG4 ROD groups), another treatment in addition to corticosteroids was more often necessary in IgG4 ROD patients (50%) than in IOIS patients (25%). CONCLUSION: After ruling out auto-immune orbital diseases, especially IgG4 ROD, IOIS should be discussed. Factors conditioning the corticosteroid response are yet to be determined.

[Diagnostic performance of imaging examinations in acute non-traumatic abdominal pain in the radiology department of the Kaolack Regional Hospital]. / Apport de l'imagerie dans la prise en charge des douleurs abdominales aigues non traumatiques au Centre Hospitalier Regional de Kaolack.

AIM: The aim of this work was to evaluate the diagnostic performance of imaging examinations in the presence of acute non-traumatic abdominal pain. MATERIALS AND METHODS: This was a prospective, cross-sectional and descriptive study over 6 months in the radiology and medical imaging department of the Kaolack Regional Hospital, including any patient received for acute non-traumatic abdominal pain with informed consent in whom the etiological diagnosis is supported by an imaging examination. We investigated the etiologies of acute abdominal pain and compared the imaging findings with surgical exploration. Our data were analyzed using SPSS 24.0 and Excel 2013 with a coefficient of significance of less than 5%. RESULTS: 106 patients were enrolled. The mean age was 32 years and the gender-ratio was 1.52 in favour of women. Acute abdominal pain was diffuse in 25.5% of patients and localized in 74.5%, of which 18.9% were at right iliac fossa.Abdominal X-ray was performed alone in 4 patients (3.8%), ultrasound alone in 46 patients (43.3%) and abdominal CT scan in 34 patients (32%). CT was combined with ultrasound in 6 patients (5.7%) and with abdominal X-ray in 16 patients (15%). The initial clinical diagnosis was corrected in 49.1% of patients. The sensitivity of the imaging compared to the final diagnosis retained was 96.2%. CONCLUSION: Imaging represents a turning point in the management of patients with acute non-traumatic abdominal pain by providing better diagnostic guidance and avoiding serious complications and unnecessary interventions.

L'ASP a été réalisé seul chez 4 patients (3,8%), l'échographie seule chez 46 patients (43,3%) et le scanner abdominal chez 34 patients (32%). Le scanner a été couplé à l'échographie chez 6 patients (5,7%) et avec l'ASP chez 16 patients (15%). Le diagnostic clinique initial a été rectifié chez 49,1% des patients. La sensibilité de l'imagerie par rapport au diagnostic final retenu était de 96,2%. CONCLUSION: L'imagerie constitue un tournant décisif dans la prise en charge des patients présentant une douleur abdominale aigüe non traumatique en apportant une meilleure orientation diagnostique évitant aux patients des complications graves et des interventions inutiles.

Prognostic value of absent end-diastolic flow within the first week following renal transplantation.

BACKGROUND: Doppler sonogram of the graft is used as a routine assessment in renal transplantation. When the resistance index (RI) equals 1, absent end-diastolic flow (AEDF) is observed; the prognostic value of AEDF is presently unknown. PATIENTS AND METHODS: Between 1988 and 1996, 342 patients received a first cadaveric kidney transplant in our ward. AEDF was observed in 30 patients who were compared with 60 controls who showed an RI < 0.75 within the first 7 days after transplantation. They were matched for year of transplantation (+/-1 year); recipient age (+/-2 years); recipient sex; and HLA antibodies (3 classes: 0%, 1-75%, >75%). The follow-up was 4 years. RESULTS: AEDF was observed at day 1 in 64%, at day 3 in 96%, and at day 7 in 28%. Recipient age, donor age, recipient sex, cold and warm ischemia durations, HLA A, B, and DR mismatches, and cytomegalovirus (CMV) status were not different between the 2 groups. Immediate graft function and 3- to 24-month creatinine levels were better in the control than the AEDF group. However, there was no difference in serum creatinine at 3 and 4 years or in patient and graft survivals during follow-up. CONCLUSIONS: AEDF observed within the first week following transplantation is associated with impaired renal functional recovery. However, whether AEDF is a prognostic marker of poor long-term graft function or survival remains to be proven.

[Chronic Right Ventricular Failure Revealing a Large Compressive Hydatid Cyst at the Cardiology Department of the Aristide le Dantec Hospital (Dakar, Senegal)]. / Une insuffisance ventriculaire droite chronique révélant un volumineux kyste hydatique compressif au service de cardiologie de l'hôpital Aristide le Dantec (Dakar, Sénégal).

Hydatidosis, an anthropozoonosis caused by the development of the Echinococcus granulosus larva in human, is a parasitic infection that is endemic in many countries. Pericardial localization in the absence of other cardiac involvement is extremely rare. Its spontaneous evolution is serious because of the risk of rupture. We report the case of a 65-year-old patient, who received limb edema that had been going on for 4 months, and in whom the physical examination noted a 3/6 tricuspid regurgitation and a right heart failure syndrome. Transthoracic echocardiography revealed an intra-pericardial mass whose contents appeared fluid with hyperechogenic area. It measured 86x61 mm and significantly compressed the straight cavities. Thoracic computed tomography showed an appearance in favor of an aged intrapericardic hydatid cyst (GHARBI V) with mass effect on the right cavities. The hydatid serology was negative. The patient did not accept the surgical cure. She had been put on albendazole and diuretic treatment. Fatal outcome was reported after two-month follow-up.

La localisation péricardique d'Echinococcus granulosus en l'absence d'une autre atteinte cardiaque est extrêmement rare. Son évolution spontanée est grave du fait du risque de rupture du kyste hydatique. Nous rapportons le cas d'une patiente de 65 ans, reçue pour des œœdèmes des membres inferieurs qui évoluaient depuis 4 mois. L'examen physique notait un souffle d'insuffisance tricuspide 3/6 et un syndrome d'insuffisance cardiaque droite. L'échocardiographie transthoracique a objectivé une masse intra-péricardique dont le contenu paraissait liquidien avec des plages hyperéchogènes. Elle mesurait 86x61 mm et comprimait de manière importante les cavités droites. La tomodensitométrie thoracique a conclu à un aspect en faveur d'un kyste hydatique (GHARBI V) intrapéricardique vieilli avec effet de masse sur les cavités droites. La sérologie hydatique était négative. La patiente n'a pas accepté la cure chirurgicale. Elle a été mise sous albendazole et traitement diurétique. L'évolution a été fatale après deux mois de suivi.

Acute circulatory failure in two cardiology departments in Dakar: 44 cases.

INTRODUCTION: Acute circulatory failure is a life-threatening emergency whose prognosis depends on early management and aetiological diagnosis. The aim of our study was to assess the epidemiological, aetiological, therapeutic and prognostic aspects of acute circulatory failure in two cardiology departments in Dakar. METHODS: This was a longitudinal, multicentre, descriptive study over a period of six months from October 2014 to March 2015. We included all patients with acute circulatory failure (systolic blood pressure < 90 mmHg, oligoanuria, tachycardia, tachypnoea, onset of altered consciousness) either on admission or during hospitalisation during the study period. A long-term survival survey (six months to one year) was conducted on all included patients. RESULTS: Forty-four patients were enrolled. The average age was 54.9 years, ranging from 20 to 83 years. The gender ratio was 1.1. Acute circulatory failure occurred most often during hospitalisation (63%), with known cardiomyopathy in 47.7% of cases. Consciousness was impaired in 11 patients while oligoanuria was present in 27.3% of cases. Inflammatory syndrome was mostly found in 63.6% of cases and renal insufficiency and acute liver failure were reported in 45.5 and 29.5% of patients, respectively. Left ventricular dysfunction was the most common echocardiographic feature (70%). Acute circulatory failure was cardiogenic in most cases, with a predominance of advanced dilated cardiomyopathy (44.9%). Septic shock was found in 25% of patients, with pulmonary infection as the main location (20%). Nine per cent of patients had hypovolaemic shock. The most used inotropic drug was dobutamine in 79.5% of cases, followed by adrenaline (18.2%) and norepinephrine (4.5%). Intra-hospital mortality rate was high (52.3%) and one-year survival rate was 27.2%. Poor prognostic factors such as advanced age and renal impairment were associated with a higher overall mortality rate of 18 to 90%, with no statistical significance. CONCLUSIONS: Acute circulatory failure is a diagnostic and therapeutic emergency with a high mortality rate.

Reflection of the effectiveness of heterosensory integration in measures of event-linked potentials.

The phenomenon of bimodal event-linked potential mismatch and summation of unimodal responses were used to study the relationship between mismatch amplitude and the effectiveness of visual-auditory integration. The effectiveness of integration was assessed in terms of the extent to which experimental measures approached the parameters of the "ideal observer." The greater the effectiveness of integration, the greater the focus of mismatch shifted from the occipital to the frontal areas of the cortex. The greatest correlation between mismatch amplitude and the effectiveness of visual-auditory integration was seen in the left frontal cortex.

[Pulmonary embolism: autopsy study of 73 cases in Senegal]. / L'embolie pulmonaire: étude nécropsique à propos de 73 cas.

INTRODUCTION: The Pulmonary emblism is a vascular disease which is characterized by the more or less complete obstruction of one or several pulmonary arteritis and/or their branches by an embol. Very polymorphic affection, mortal in the massiv form, it has in the average forms of the atypical or misleading aspects which make its clinical diagnosis difficult. The diagnostic strategy of the pulmonary embolism remains incompletely solved. The objectives of this work are: --to evaluate the prevalence with the autopsy of the pulmonary embolism and its distribution according to the age, --to appreciate the correlation enters the ante and the post-mortems diagnoses. PATIENTS AND METHODS: It is about a retrospective study, over 10 years period, having inclued the files of all the patients died in the various services of medicine or surgery of the university hospital of Aristide Le Dantec but also those transferred from outside of the hospital and at which the pulmonary diagnosis post-mortem of embolism was retained. RESULTS: Sixty thirteen (73) cases of pulmonary embolism had been found during autopsies during the period of study (10 ans), that is to say a prevalence of 1.9%. The average was 35 years. The most representative age bracket was that ranging beetwin 21 and 30 years is 36% of the studied population. On the 73 indexed patients, 30 (41%) were transferred from outside of the hospital and 43 (59%) came from the servicies of medecine and surgery with a prevalance of the service of cardiology (26%). The correlation beetween ante-mortems diagnosis and the anatomical result was 11% for the whole of the patients incleded in the study. However, it was 42% for the sub-grup of patients comming from the service of cardiology. CONCLUSION: The prevalence with the autopsy of pulmonary embolism is weak. The clinical diagnosis of this affection is difficult even in a specilised service with a high rate of negatif forgeries. This pathology is very under- evaluated even in these services.

[Ambulatory Blood Pressure Measurement's Reults And Indications At Cadiology Department At Hôpital Aristide Le Dantec]. / Indications Et Resultats De La Mesure Ambulatoire De Pression Arterielle Au Service De Cardiologie De L'Hopital Aristide Le Dantec.

High blood pressure (HTA) is a public health problem. It affects more than one billion people around the world, more than a quarter of the world's population. In recent years the ABPM (Ambulatory Blood Pressure Measurement) has become a valuable and widely used tool for the diagnosis and management of hypertension. The aims of this study were to determine the indications of MAPA to the cardiology department of Aristide le Dantec Hospital; to determine the results and to evaluate the blood pressure profile of our patients. METHODS: We carried out a retrospective study, over 37 months from December 2010 to December 2013 covering all the results of the ABPMs recorded during this period. Was included any patient over 18 years of age with an ABPM. All ABPMs with less than 50 good measures per 24 hours were not included. RESULTS: A total of 204 MAPA results were included of a total of 307. The mean age was 49.6 ± 11.5 years with extremes of 25 years and 78 years. The sex ratio was 1.5 in favour of women. Indications were dominated by labile HTA (34.8%); masked HTA (27.9%) and suspicious of the white coat effect (12.3%). The analysis of the results showed that MAPA was normal in 49.5%. The white coat effect was found in 32% (65 patients) of ABPM. In patients with abnormal ABPM, permanent systolic-diastolic hypertension predominated (57%). HTA masked was noted in 25.7% of our patients and HTA white coat was found in 3.8% of cases. In the hypertensive patients treated, MAPA revealed a poor blood pressure balance in 42.1%. Among the HTA prognostic factors we noted32.4% of patients were "Non Dippers", a pulse pressure greater than or equal to 60 mmHg in 59%. CONCLUSION: The use of this exploration is an important aid to practitioners in the diagnostic, therapeutic and prognosis phase of the management of hypertension. It should become more important as it provides better information on the blood pressure profile for the patients.

INTRODUCTION: L'hypertension artérielle(HTA) représente un problème de santé publique. Elle concerne plus d'un milliard d'individus à travers le monde, soit plus du quart de la population mondiale. Ces dernières années la MAPA (mesure ambulatoire de la pression artérielle) est devenue un outil précieux et largement utilisé pour le diagnostic et la prise en charge de l'HTA. Les objectifs de ce travail étaient de déterminer les indications de la MAPA au service de cardiologie de l'hôpital Aristide le Dantec ; d'en déterminer les résultats et d'évaluer le profil tensionnel de nos patients. MÉTHODES: Nous avons réalisé une étude rétrospective, sur 37 mois allant de Décembre 2010 à Décembre 2013 portant sur l'ensemble des résultats des MAPA enregistrées durant cette période. Était inclus tout patient âgé de plus de 18 ans chez qui une MAPA a été enregistré Toutes les MAPA ayant moins de 50 bonnes mesures par 24 heures n'ont pas été inclus. RÉSULTATS: Au total 204 résultats de MAPA ont été inclus sur un total de 307. L'âge moyen était de 49,6 ± 11,5 ans avec des extrêmes de 25 ans et 78 ans. Le sex ratio était de 1,5 en faveur des femmes. Les indications étaient dominées par l'HTA labile (34,8%) ; l'HTA masquée (27,9%) et la recherche de l'effet blouse blanche (12,3%). L'analyse des résultats avait montré que la MAPA était normale dans 49,5% des cas. L'effet blouse blanche était retrouvé dans 32% (65 patients) des MAPA réalisées à visée diagnostique. Chez les patients dont les résultats étaient anormaux l'HTA systolo-diastolique permanente prédominait (57%) avec une différence significative (p=0,003). L'HTA masquée étaient notée chez 25,7% de nos patients et l'HTA blouse blanche était retrouvée dans 3,8% des cas. Chez les hypertendus traités, la MAPA avait révélé un mauvais équilibre tensionnel dans 42.1% des cas et cela au dépens de la systolique avec une différence significative (p=0,02). Parmi les facteurs pronostiques on retrouvait 32,4% de patients « Non Dippers ¼, une pression pulsée supérieure ou égale à 60 mm Hg dans 59%. Le caractère adrénergique était retrouvé chez 65,7% de nos patients. CONCLUSION: L'utilisation de cette exploration constitue une aide importante aux praticiens à la phase diagnostique, thérapeutique, et pronostique de la prise en charge de l'HTA. Elle devrait occuper de plus en plus de place car elle donne de meilleurs renseignements sur le profil tensionnel dans l'environnement quotidien habituel du patient.

[Representation of heterosensory integration effectiveness in parameters of event-related potentials].

A phenomenon of a mismatch of the bimodal ERP and the sum of unimodal ERPs was used in our research. It was investigated how the mismatch amplitude depends on audio-visual integration effectiveness. The effectiveness was calculated on basis of approximation degree of an experimental performance to parameters of "ideal observer". It was determined, the higher the subject's integration effectiveness is, the rostraler the mismatch focus localization is. The highest correlation of the mismatch amplitude and the audio-visual integration effectiveness was revealed in the left frontal cortex.

[Comparative Study Of Coronary Artery Disease In Diabetics And Non-Diabetics In The Department Of Cardiology Of Aristide Le Dantec University Hospital]. / Etude Comparative De La Maladie Coronaire Chez Les Diabétiques Et Non Diabétiques Au Service De Cardiologie Du CHU Aristide Le Dantec.

The aim of this study was to compare the features of coronary artery disease between diabetic and non-diabetic patients. PATIENTS AND METHODS: A case-control study was carried out from 1 May 2013 to 31 July 2015 in the department of cardiology of Aristide le Dantec university hospital. Forty-five diabetic patients and forty-five non-diabetic patients who underwent coronary angiography and / or angioplasty were included. RESULTS: There was a male predominance with a sex ratio of 1.6 in both groups. The mean age was 62.26 years for diabetics and 59.06 years for non-diabetics (p = 0.6). In diabetics, symptomatology was dominated by silent ischemia (48.9%) versus typical angina pain (68.9%) in non-diabetics. Myocardial infarction was the most common indication of coronary angiography in both groups. Coronary angiography revealed one-vessel disease (46.6% versus 41.7% p = 0.822), double vessel disease (26.7% versus 41.7% p = 0.091) and triple vessel disease (26.7% versus 16.6% p = 0.561). Angioplasty was indicated in 37.8% of diabetics versus 63.9% of non-diabetics. Nine diabetic patients and three non-diabetic patients had an indication of coronary artery bypass grafting. CONCLUSION: Our study confirms the greater frequency of silent ischemia and multiple-vessel disease in diabetics as well as a more frequent indication of coronary artery bypass grafting in these patients.

L'objectif de cette étude était de comparer les aspects de la maladie coronaire entre les patients diabétiques et non diabétiques. PATIENTS ET MÉTHODES: Une étude cas-témoins a été réalisée du 1er mai 2013 au 31 juillet 2015 au service de cardiologie du CHU Aristide le Dantec. Quarante cinq patients diabétiques et 45 patients non diabétiques ayant bénéficié d'une coronarographie et/ou d'une angioplastie avaient été inclus. RÉSULTATS: Nous avions retrouvé une prédominance masculine avec un sex ratio de 1,6 dans les deux groupes. L'âge moyen était de 62,26 ans pour les diabétiques et de 59,06 ans pour les non diabétiques (p=0,6). Chez les diabétiques, la symptomatologie était dominée par l'ischémie silencieuse (48,9%) et la douleur angineuse typique (68,9%) chez les non diabétiques. L'infarctus du myocarde était l'indication de la coronarographie la plus fréquente dans les deux groupes. La coronarographie retrouvait respectivement chez les diabétiques et non diabétiques une atteinte mono-tronculaire (46,6% versus 41,7% p=0,822), une atteinte bi-tronculaire (26,7% versus 41,7% p=0,091) et une atteinte tri-tronculaire (26.7% versus 16,6 % p=0,561). Une angioplastie avait été indiquée chez (37,8%) des diabétiques et (63,9%) des non diabétiques. Neuf patients diabétiques et trois patients non diabétiques avaient eu une indication de pontage coronaire. CONCLUSION: Notre étude confirme une plus grande fréquence de l'ischémie silencieuse et de l'atteinte multi tronculaire chez les diabétiques ainsi qu'une indication plus fréquente de pontage aorto coronaire.

[Combined heart and kidney transplantation in Fabry's disease: Long-term outcomes in two patients]. / Transplantation combinée cœur­rein au cours de la maladie de Fabry : suivi à long terme de deux patients.

INTRODUCTION: Fabry disease is a lysosomal storage disorder linked to an alpha-galactosidase A deficiency that can lead to heart and kidney failure. There is little data about the prognosis of patients who undergo a combined heart and kidney transplantation. CASE REPORTS: Two brothers who were diagnosed with Fabry disease after the age of 30 years underwent a combined heart and kidney transplantation at respectively 49 and 42 years of age because of a severe hypertrophic cardiomyopathy with end stage renal failure. They are alive respectively 4 and 9 years after the transplantation. No recurrence of the disease in the transplanted organs has been found. CONCLUSION: Combined heart and kidney transplantation in Fabry disease is an efficient therapy for the cardiomyopathy and kidney failure. Its prognosis can be good when the patients are carefully selected. However, an early diagnosis is critical in order to avoid a procedure associated with a high perioperative mortality.

[Prevalence of dyslipidemia in the rural population of Gueoul (Senegal)]. / Prévalence de la dyslipidémie dans la population rurale de Guéoul (Sénégal).

INTRODUCTION: The cardiovascular risk factors are clearly increasing in developing countries. Among these factors, dyslipidemia is often found, this due to the change in behavioral and dietary habits (OMS, 2006). Dyslipidemia is a "primary or secondary pathological changes in serum lipids". It is a chronic and metabolic abnormality, characterized by persistently elevated TG, LDL-c, and a decrease in HDL (Attias et al., 2013-2014). The objective of this study is to determine the prevalence of dyslipidemia, and give the lipid profile of the population in Gueoul. PATIENTS AND METHODS: We performed a comprehensive observational study, cross-sectional descriptive on Senegalese aged 35 or over, living in Gueoul for at least 6 months. Lipid profile (total cholesterol, triglycerides, HDL-cholesterol, LDL-cholesterol) was systematically after 12hours of fasting. RESULTS: Dyslipidemia was found in 61.3 % of cases with 50 % pure hypercholesterolemia (n=705). Only 20 subjects (2.3 %) knew they had dyslipidemia. The detection rate was 59.8 % (n=844). The type most represented was hypoHDLemia (45.6 %) followed by hyperLDLemia (28.8 %). Triglycerides were increased in only 2.8 % of cases. CONCLUSION: The prevalence of dyslipidemia is very high in our regions. It is often associated with female gender, hypertension, diabetes, and obesity. Its main causes are physical inactivity, change in lifestyle and eating habits. It is often misunderstood and its management is limited in most cases to low-calorie diet.

[Study of echocardiographic parameters of rheumatoid arthritis black African without clinically evident cardiovascular manifestations: A cross-sectional study of 73 cases in Senegal]. / Étude des paramètres échocardiographiques de la polyarthrite rhumatoïde noire africaine asymptomatique au plan cardiovasculaire : étude transversale de 73 cas sénégalais.

INTRODUCTION: Research of cardiac involvement in patients with rheumatoid arthritis can prevent complications and place in a logical secondary prevention. The objective of this study was to investigate the echocardiographic parameters in a population of Senegalese patients with rheumatoid arthritis without clinically evident cardiovascular manifestations. PATIENTS AND METHOD: We conducted a descriptive cross-sectional study, which included prospectively from outpatients in the internal medicine department of university hospital center Aristide Le Dantec in Dakar, Senegal, with a diagnosis of rheumatoid arthritis without clinically evident cardiovascular disease. It focused on a sample of 73 patients of both sexes aged at least 18 years. Following clinical examination, we conducted laboratory tests (CRP, fibrinogen, ESR, rheumatoid factors: Latex and Waaler-Rose, anti-CCP, antinuclear factors and anti-ENA antibodies), ECG, echocardiography standard. Data were analyzed using a descriptive study of the different variables with the calculation of proportions for categorical variables, and the positional parameters and dispersion for quantitative variables. RESULTS: A total of 73 patients with rheumatoid arthritis without obvious cardiac events and meeting the criteria of definition of the ACR 1987 were included in the study. The mean age was 44.17±14.43 years with extremes of 18 and 75 years. The mean duration of RA was 5.93±4.78 years. The concept of family inflammatory arthritis was reported in 35.60% of cases and almost one in six patients had at least a factor of cardiovascular risk (16.96%). The abnormalities found in Doppler echocardiography were dominated by diastolic LV dysfunction (42.46%), increased left ventricular mass in 35.61%. Valvular leaks of variable grades were highlighted regarding all orifices but were rarely significant. CONCLUSION: The realization of echocardiography in patients with rheumatoid arthritis without clinically evident cardiovascular manifestations helps to highlight cardiovascular abnormalities related to the natural course of the disease.
