Surdité brusque: étude rétrospective à propos de 36 cas

L’Objectif de cette étude est de rapporter notre expérience concernant la prise en charge des surdités brusques en soulignant la notion d’urgence, et en montrant les facteurs influant la probabilité de récupération. Nous rapportons une étude rétrospective concernant 36 patients colligés au service ORL de l’Hôpital Militaire Avicenne de Marrakech au Maroc, pendant 05 ans. Uniquement les surdités brusques unilatérales ont été incluses dans notre étude. Il s’agit de 21 oreilles droites et 15 gauches. Les données cliniques étaient recueillies par l’interrogatoire et l’examen clinique complet. L’évolution du déficit auditif a été évaluée à l’admission, toutes les 48 heures et après arrêt du traitement par audiométrie tonale liminaire. Tous nos patients ont bénéficié des potentiels évoqués auditifs du tronc cérébral, 09 d’entre eux d’une tomodensitométrie. Une IRM a été réalisée chez une seule patiente. Le protocole thérapeutique comprend des corticostéroïdes, vasodilatateurs. Seulement 16,6 % des patients ont récupéré la totalité de la perte auditive initiale. Les potentiels évoqués auditifs (P.E.A) ont décelé un cas de neurinome de l’acoustique confirmé par l’imagerie

Un cas isolé de tuberculose appendiculaire

La tuberculose est une affection qui sévit à l’état endémique dans notre pays, elle demeure un problème majeur de santé publique .la tuberculose appendiculaire primitive est une affection très rare. Nous rapportons le cas d'un patient de sexe masculin âgé de 17 ans, admis au service pour une prise en charge d'une douleur de la fosse iliaque droite évoluant dans un contexte fébrile avec conservation de l’état général posant le diagnostic d'une appendicite aigue. Une appendicectomie a été réalisée ; le compte rendu anatomopathologique était en faveur d'une tuberculose appendiculaire isolée. Le patient a été mis sous traitement anti-bacillaire complémentaire pendant neuf mois avec une bonne évolution clinique. Le diagnostic de tuberculose doit être évoqué en premier surtout dans les pays d'endémie tuberculeuse

Kyste hydatique du foie rompu dans la paroi abdominale et dans le muscle psoas : à propos d'une rare observation

Le kyste hydatique du foie est une parasitose qui sévit à l′état endémique au maroc. La rupture dans la paroi abdominale et dans le psoas est une complication exceptionnelle. Nous rapportons un cas de kyste hydatique du foie rompu dans la paroi et dans le muscle psoas. Le diagnostic a été établi sur les données de l′échographie et surtout de la tomodensitométrie. Le patient a été opéré avec des suites simples

Giant splenic cysts discovered incidentally after early abortion

Splenic cysts are rare tumors, grouped into parasitic and non-parasitic cysts, no-parasitic cysts are further classified into primary and secondary cysts depending on the mucous membrane of the cyst, radiological imaging allows the diagnosis to be made but confirmation of the diagnosis is based on an atom-o-pathological examination of the part. surgical treatment is the cornerstone of symptomatic and complicated splenic cysts. The conservative treatment is a reference for splenic cysts. We report the case of a young woman who was presented with a simple cyst of the spleen

Métastase pariétale d’un adénocarcinome bronchique

Les métastases cutanées du carcinome bronchogénique sont rares, elles témoignent d'un stade tardif de la maladie. Nous rapportons le cas d'une métastase cutanée d'un adénocarcinome bronchique traitée chirurgicalement en vue d'améliorer le confort du malade

ISSN 2347-954X (Print) Unaccustomed Localizations of Hydatic Cyst Experience of the Service

Abstract: The hydatid cyst is a cosmopolitan parasitic infection that constitutes a problem of the public health in the zones of raising of the developing countries. We return the result of a retrospective survey of 64 cases of unaccustomed localizations of hydatid cysts collected in the general surgery service of the Avicenne military hospital on one period of 17years. The middle age of our patients is of 32years with extremes going from 9 at 66 years. The clinical symptom depended on the seat of the hydatid cyst and the medical imagery permitted to put the diagnosis in the majority of the cases. All patients have been operated and the operative gesture was the most conservative possible and it varied according to the seat and the character of the lesion. The operative mortality is hopeless and the morbidity is at the surroundings of 20%.The human Hydatid disease provoked by the larval shape of a tapeworm of the dog: the echinococcus granulosis. It is an anthropozoonose that rages in several countries from the world to the endemic state. The localizations of predilection are the liver and the lungs of which they represent 85% of the cases; but in practice all organ can be reached. We returned in this survey 64 cases of rare and unaccustomed localizations of hydatid cyst. In conclusion, the hydatid cyst constitutes a real public health problem. It is always necessary to think of it especially among subjects living in a country to elevated endemic and to ask for the necessary complementary exams to put the diagnosis and to avoid therapeutic mistakes. The eradication of this affection rests on the prophylaxis

ZnCr-LDHs with dual adsorption and photocatalysis capability for the removal of acid orange 7 dye in aqueous solution

International audienceThis study aims to explore the potential of layered double hydroxides (LDHs) materials for the treatment of contaminated waters by organic pollutants, using a combined dual process, namely adsorption-photocatalysis. A series of LDHs of ZnCr-X where (X = Cl, SO4 and CO3) were synthesized and characterized by several techniques such as DRX, FTIR, BET, TEM, and UV-Visible spectrophotometry. The pollutant acid orange 7 (AO7) is efficiently adsorbed on the surface of the three LDHs. The adsorption depends on the nature of the intercalated anion. The adsorption percentage of AO7 achieved for the intercalated anions , and Cl−, was 25, 32 and 49.5% respectively. We find that ZnCr–SO4 LHD is the most effective photocatalyst for AO7 dye decomposition in the UV and visible range and its photocatalytic activity is preserved during three cycles of photocatalytic tests. Such remarkable properties allow considering ZnCrSO4-LDH as a promising photocatalyst with high activity, long-term durability and excellent applicability

Enhanced photocatalytic activity of hydrozincite-TiO2 nanocomposite by copper for removal of pharmaceutical pollutant mefenamic acid in aqueous solution

International audienceNanocomposites based on Hydrozincite-TiO 2 and copper-doped HZ-xCu-TiO 2 (x= 0.1; 0.25; 0.35) were synthesized in a single step using the urea method. The samples were characterized by XRD, FTIR, SEM/TEM and DRS. The study of adsorption capacity and photocatalytic efficiency of these nanocomposites have been tested on a pharmaceutical pollutant, mefenamic acid (MFA). Kinetic study of removal of MFA, indicates that this pollutant was adsorbed on the surface of the synthesized phases, according to Langmuir's model. Such adsorption proved to be well adapted in a kinetic pseudo-second order model with capacity of 13.08 mg/g for HZ-0.25Cu-TiO 2. Subsequently, the kinetics of photocatalytic degradation under UV-visible irradiation was studied according to several parameters, which allowed us to optimize our experimental conditions. The nanocomposite HZ-0.25Cu-TiO 2 showed significant removal efficiency of MFA. Elimination rate reached 100% after 20 min under UV-vis irradiation, and 77% after 7h under visible light irradiation. Repeatability tests have shown that this nanocomposite is extremely stable after six photocatalytic cycles. By-products of MFA were detected by LC/MS. These photoproducts produced by three types of reactions of hydroxylation; cyclization and cleavage of the aromatic ring. MFA underwent complete mineralization after 22 h of irradiation in the presence of the HZ-0.25Cu-TiO 2
