[Appendiceal Duplication In A Patient Operated For Chilled Appendix Breastplate At Gao Regional Hospital]. / Duplication Appendiculaire Chez Une Patiente Operee Pour Plastron Appendiculaire Refroidi A L'Hopital Regional De Gao, A Propos D'Un Cas.

Appendiceal duplication is the very rare malformation. It was first described by Picoli in 1892. It is a condition that is most often seen in the first years of life, sometimes some forms may remain asymptomatic and only occur in adulthood. We report the case of appendiceal duplication in a patient operated for chilled appendix breastplate at Gao Regional Hospital. CONCLUSION: appendiceal duplication is a rare abnormal abnormality of intraoperative discovery in general. Each surgeon must think about it during an appendectomy.

La duplication appendiculaire est une malformation très rare. Elle a été décrite pour la première fois par Picoli en 1892. C'est une affection qui se manifeste le plus souvent dans les premières années de vie, parfois certaines formes peuvent rester asymptomatiques et ne s'expriment qu'à l'âge adulte. Nous rapportons le cas de duplication appendiculaire chez une patiente opérée pour plastron appendiculaire refroidi à l'hôpital régional de Gao. CONCLUSION: la duplication appendiculaire est une anomalie malformative rare de découverte per opératoire en général. Chaque chirurgien doit y penser au cours d'une appendicectomie.

[Interest of laparoscopic surgery in the management of chronic abdominal pains in the surgery "A" department of the of the Point G University Hospital]. / Interet de la laparoscopie dans la prise en charge des douleurs abdominales chroniques dans le service de chirurgie "A" du CHU du Point G.

AIM: to evaluate the contribution of laparoscopic surgery in the management of chronic abdominal pains of unspecified etiology. METHODS: A retrospective descriptive study was conducted over a period of 49 months (March 2008 to March 2012), in the surgery A service of the Point G university hospital. RESULTS: 52 patients suffering from chronic abdominal pain for 3 months have been listed. There were 36 women and 16 men, with a sex-ratio of 2.25. The pathologies found in laparoscopy were: 16 cases of adherences, 16 cases of gynaecological diseases, 6 cases of chronic appendicitis, 5 cases of chronic cholecystitis, 6 cases of abdominal tumors and 3 cases of intrauterine contraceptives in abdomen. Conversion to laparotomy was not made and mortality was null. No lesion was found in 11.54% of cases. The mean duration of hospitalization was 2 days. The duration of follow-up of the patients was 18 months with a minimum of 6 months and a maximum of 24 months. No painful symptomatology was found in 6 months in 88.46% of the cases. Persistent stomach pains were found in 3% of the cases. 8.54% of the patients had an improvement of symptomatology. CONCLUSION: Chronic abdominal pains put a diagnosis problem in surgery. Laparoscopy is a reference technique to diagnose this pain and to discuss them.

BUT: évaluer l'apport de la chirurgie laparoscopique dans la prise en charge des douleurs abdominales chroniques d'étiologie indéterminée. MÉTHODE: Il s'agissait d'une étude rétrospective et descriptive sur une période de 49 mois (mars 2008 à mars 2012), dans le service de chirurgie A du CHU du point G.

Identifying barriers to effective tuberculosis control in Senegal: an anthropological approach.

SETTING: Low tuberculosis (TB) cure rates (average 53%) and high treatment default rates (average 28%) were reported in Senegal between 1999 and 2001. OBJECTIVE: To qualitatively evaluate the ability of TB patients to access and complete treatment in Senegal, with a view to helping to develop suitable strategies to improve TB control. METHODS: Anthropological study conducted in a series of public and private, urban and rural health facilities in 2001 and 2002. The qualitative methods used included semi-structured and in-depth interviews of health staff, patients and relatives, focus group discussions, and observations carried in health facilities. RESULTS: Problems were identified at several levels of health care. The main impediments to successful patient outcomes identified were: limited access to TB diagnosis and treatment facilities, poor communication between health personnel and patients, poor quality information provided to patients, poorly applied directly observed treatment, lack of a strategy to trace defaulting patients and limited supervision of the treatment units by the district leadership team. CONCLUSION: The anthropological analysis of patient care is an appropriate means of addressing complex public health problems in disease control and identifying solutions that are acceptable, sustainable and adapted to the local context.

[Tuberculosis control in Senegal: update on care services and recommendations for improvement]. / La lutte contre la tuberculose au Sénégal: situation actuelle de la prise en charge et recommandations pour son amélioration.

The goal of this study was to evaluate tuberculosis control in Senegal especially with regard to organization, quality, and availability of care services. Study was carried out from January to October 2002 within the framework of the National Turberculosis Control Program (NTCP) in 10 public hospitals and 8 private facilities including 4 doctors' offices, 2 company medical dispensaries, and 2 medical laboratories. Case observations were collected at the same time as surveying of diagnostic and therapeutic departments. In addition NTCP records for the period from 2000 to 2001 were searched. The reporting rate of new cases confirmed by positive smears is still low in Senegal, (62/100 000 inhabitants). Reporting is particularly low in rural areas where a clear-cut male predominance was observed. The cure rate also remains low (mean, 62%) mainly due to failure to complete treatment (28%). This situation contrasts with the extensive resources that have been devoted to diagnosis and treatment including field units for diagnosis (76 laboratories) and treatment (68 centers). These facilities are well integrated into the healthcare system and distributed nation-wide and provide effective care free of charge. The findings of this study demonstrate that there are serious impediments to control of tuberculosis in Senegal. Recommendations are made at various levels based on the results of problem analysis and are used to develop new management strategies aimed at improving NTCP performance indicators in Senegal.

Elemental analysis of soft plaque and calcified plaque deposits from human coronary arteries and aorta.

Twenty-five samples of soft plaque and calcified plaque deposits from human hearts or aorta were analyzed using inductively coupled plasma-mass spectrometry (ICP-MS). The determined elements were Ca, P, Na, K, Mg, Zn, Cu, Ba, Pb, Fe, Al, Si, and S. Results showed that the concentration of all elements in the soft plaque was at the micromolar level. In the calcified deposits, the concentrations of Ca and P were at least an order of magnitude higher than the soft plaque, but the other elements were at the same order of magnitude. In the calcified plaque the molar ratios of Ca/P suggested that a significant portion existed as hydroxyapatite Ca10(PO4)6(OH)3. However, their absolute concentrations indicated that this compound was not a major component of the plaque although it may play a major role in determining the crystal structure of the deposit. In some samples the Ca/P ratio was too high to conform to hydroxyapatite. In others it was too low. This indicated that both the calcium and phosphorus existed in other chemical forms which varied from sample to sample. In the soft tissue the P level was high indicating it existed primarily in chemical forms other than hydroxyapatite. The presence of homocysteine is often associated with heart disease. However, the low levels of sulfur indicate that although it may be present, it is not a major component of the plaque, but may nevertheless play an important role in its formation.

Elution behavior of unsaponifiable lipids with various capillary electrochromatographic stationary phases.

Capillary electrochromatographic (CEC) separations of unsaponifiable lipids, tocopherols (T), tocotrienols (T3), and plant sterols were studied under various conditions. Investigated stationary phases include pentafluorophenylsilica (PFPS), triacontylsilica (TCS), and octadecylsilica (ODS) phases. A baseline separation of four sterols (ergosterol, lanosterol, sitosterol and stigmasterol) on ODS was achieved and their elution order was found to be dictated by side-chain structures. CEC of the tocol-derived compounds on PFPS in aqueous methanol yielded the most satisfactory results with complete resolution of all components eluting in the order deltaT3>beta3>gammaT3>epsilonP>alphaT3>deltaT>zeta2T>betaT>gammaT>alphaT, while a reversal in elution of the epsilonT-alphaT3 pair was observed in aqueous acetonitrile. CEC with a TCS phase in non-aqueous methanol led to a different elution pattern deltaT3>gammaT3>betaT3>alphaT3epsilonT>deltaT>(zeta2+gamma)T>betaT>alphaT, despite favorable resolution of the (gamma-zeta2)T pair along with the observation of inseparable(beta-gamma)T and (beta-gamma)T3 pairs in non-aqueous dimethylformamide. Non-aqueous acetonitrile mobile phases provided unique selectivity for the (gamma-zeta2)T pair and isomer separations on TCS. Variations in separation and retention factors of relevant antioxidant species with CEC variables were evaluated. Examples of CEC quantification of unsaponifiable fractions of rice bran oils and soybean oils are presented.

Capillary electrochromatography of cholesterol and its ester derivatives.

Separation of cholesterol and its ester derivatives using micellar electrokinetic chromatography is a challenge due to the extreme hydrophobicity of these compounds. In this work, an isocratic capillary electrochromatography (CEC) method has been developed to separate a complex mixture of cholesterol and its 12-ester derivatives. The proportions of mobile phase (tetrahydrofuran, acetonitrile, water), as well as the effects of acid modifiers, buffer concentrations, voltage, and temperature on the separation of cholesterol derivatives were investigated. Addition of a polymeric surfactant, poly(sodium N-undecanoyl-L-glycinate), to the mobile phase reduced migration time and improved resolution of the analytes. The CEC method developed allows baseline separation of a complex mixture of cholesterol and 12 ester derivatives in less than 40 min. Finally, the method is applied to the characterization of cholesterol, cholesterol linoleate, and cholesterol oleate extracted from atherosclerotic plaque deposits in the arterial walls of a human aorta.

[Left ventricular aneurysm in human immunodeficiency virus infection: a case report]. / Anévrisme ventriculaire gauche au cours de l'infection par le virus de l'immuno-déficience humaine. A propos d'une observation.

The authors report the case of a 30 year old man with a left ventricular aneurysm who was seropositive to HIV 1 and HIV 2. The patient was stage IVC 1 (AIDS related complex) by the "Center for Disease Control" classification. The clinical presentation was pyrexia, loss of weight, micropolyadenopathy and cardiac failure. The electrocardiogramme showed low voltage in the peripheral leads with a QS morphology in S2, S3 and aVF and abrasion, of the R wave in the precordial leads. Doppler echocardiography demonstrated a large left ventricular aneurysm with a wide neck. Despite treatment with a diuretic, angiotensin converting enzyme inhibitor and anticoagulants, the patient died suddenly. Autopsy confirmed the wide necked left ventricular aneurysm. This would appear to be the first report of this form of cardiac disease during HIV infection. However, a simple coincidence of the two pathologies cannot be excluded.
