Gestion péri opératoire d’un paragangliome rétro-péritonéal

Nous rapportons l'observation d'un patient âgé de 62 ans qui présente des douleurs abdominales avec une masse du flanc droit. Les explorations morphologiques ainsi que les données biologiques ont permis de faire le diagnostic d'un paragangliome secrétant. Les particularités diagnostiques ainsi que la gestion périopératoire sont envisagées

Kyste hydatique cervico mediastinal a propos d’un cas

Le kyste hydatique cervico-médiastinal est extrêmement rare même en pays d’endémie. Il se manifeste généralement par une masse cervico-thoracique et il pose un problème délicat de diagnostic. Les auteurs rapportent le cas d’une femme de 53 ans, qui a consulté pour une masse sus claviculaire gauche évoluant depuis une année. Le bilan radiologique avait conclu au début à un magma d’adénopathies cervico-médiastinales. La patiente a bénéficié, alors, d’une cervicotomie exploratrice avec la découverte en per-opératoire d’un kyste hydatique cervico- médiastinal.Mots clé : Kyste hydatique, localisation cervico-médiastinale, imagerie

Purification of artemisinin excerpt from Artemisia annua L

The active pharmaceutical substance artemisinin found in Artemisia annua L. remains the most effective remedy against malaria. The objective of this work is the purification of the active ingredient through a natural matrix composed of clay sandwiched by aluminum. The purification process is carried by adsorption of the extracts on sodium type and bridged clay type. The XRD characterization of this material shows an increase in the basal distance of 10 Å to 17 Å. This shows the success of the intercalation of aluminum polycation. We find a better purification of the extract when using aluminum bridged clay compared to sodium clay. The best performance of 80.64% adsorption is obtained at 40 ° C for the clay matrix bridged with aluminum complex

Study of some parameters influence on a Saharian building balance sheet

This work has undertaken a study of the influence of some parameters on the energy balance of a premise located in an arid area. The objective of this study is to calculate the heat of a South facing office record, and study the influence of various parameters such as: glazing, insulation, orientation, building materials and occupants. The system is composed of a desktop represented by its design, and external surrounding climatic condition of Bechar city

Study of heat and mass transfer through an earth to air heat exchanger equipped with fan in south west of Algeria

Earth to air heat exchanger is a very old technique used 3000 years B.C in arid regions where that was called Qanat. In the present experimental study, the potentials of earth to air heat exchanger to provide thermal comfort for winter weather conditions in South west of Algeria described as arid region are investigated. An EAHE made of 66 meter of PVC tube and buried at 1.5 meter underground in agriculture zone equipped with 33 W fan was studied. Thermal and hygrometric analysis of air passing inside the tube form inlet to outlet was conducted. The results show the system was able to create two thermal regimes: heating regime with a gain of 13 degrees C (from 00h to 11h and from 17h to 23h) and cooling regime (from 12h to 16h) with 6 degrees C in the same day. Relative humidity was reduced by 32 % of 90 % of studied cases which stops the development of micro-organism and reducing Internal Air Quality

Impact of systematic advanced care planning in lung cancer patients: A prospective study

International audienceBackground: End-of-life (EOL) communication is crucial, particularly for cancer patients. While advanced care planning is still uncommon, we sought to investigate its impact on care intensity in case of organ failure in lung cancer patients.Methods: We prospectively included consecutive lung cancer patients hospitalised at the Grenoble University Hospital, France, between January 1, 2014 and March 31, 2016. Patients could be admitted several times and benefited from advanced care planning based on three care intensities: intensive care, maximal medical care, and exclusive palliative care. Patients' wishes were addressed.Results: Data of 739 hospitalisations concerning 482 patients were studied. During the three first admissions, 173 (25%) patients developed organ failure, with intensive care proposed to 56 (32%), maximal medical care to 104 (60%), and exclusive palliative care to 13 (8%). Median time to organ failure was 9 days [IQR 25%-75%: 3-13]. All patients benefited from care intensity that was either equal to or lower than the care proposed. Specific wishes were recorded for 158 (91%) patients, with a discussion about EOL conditions held in 116 (73%).Conclusions: In case of organ failure, advanced care planning helps provide reasonable care intensity. The role of the patient's wishes as to the proposed care must be further investigated.Clinical trial registration: The study was registered at www.ClinicalTrials.gov with the identifier NCT02852629
