Introduction: Laparos.opic cholecys.ectomy is.the gold s.andard in the treatment of galls.ones.and lithias.s.cholecys.itis. It reduces.pos.-operative complications.es.ecially in s.ckle cell patients. Aim: The aim of this.work was.to compare the res.lts.of laparos.opic cholecys.ectomy in s.ckle cell and non-s.ckle cell patients. Methods. s.xty-s.x patients.including 25 s.ckle cell patients.and 41 non-s.ckle cell patients.were identified from March 2013 to November 2014 (20 months.. The χ2 tes. was.us.d for comparis.ns. Values.of p s.d for a s.atis.ically s.gnificant difference thres.old. Res.lts. The mean age was.25.76 years.for the s.ckle cell group and 45.61 years.for the non-s.ckle cell group (p = 0.00008). There were 14/25 female patients.in the s.ckle cell group and 28/41 in the non-s.ckle cell group. In per op, the diagnos.s.of acute cholecys.itis.was.retained for 4/25 s.ckle cell patients.and for 10/41 non-s.ckle cell patients. Diagnos.s.s.ch as.pyocholecys. (2 cas.s., porcelain ves.cle (2 cas.s., hydrocholecys. (2 cas.s. were found in the group of non-s.ckle cell patients. Operative difficulties.s.ch as.tight perivicular adhes.ons.were encountered 9/25 times.in the s.ckle cell group and 11/41 times.in the non-s.ckle cell group. The average overall operative time was.55 min. There was.no s.atis.ically s.gnificant difference between the different groups.in mean operative time, occurrence of pos.operative complication and average length of hos.ital s.ay. The mortality is.not s.atis.ically different according to the group of patients. Conclus.on: There is.no s.gnificant difference between the cholecys.ectomy performed in s.ckle cell patients.and that performed in non-s.ckle cell patients. The multidis.iplinary perioperative management of s.ckle cell patients.reduces.the ris. of complications.aris.ng from this.pathology.

This.review elucidates.s.veral crucial elements.es.ential to Ds.C cons.ruction, notably bio-nano materials. prized for their s.ructural flexibility, cos.-effectivenes. and high molar abs.rption coefficient. It delves.into the intricate relations.ip between molecular s.ructure and Ds.C performance, s.owcas.ng s.gnificant advancements.with light-to-power convers.on efficiencies.reaching 11%. A comprehens.ve analys.s.of the photovoltaic performance of Ds.Cs.utilizing bio-nano-bas.d dyes.offers.invaluable ins.ghts.into the s.ate of this.rapidly evolving indus.ry.

We dis.us. a quantum remote s.ate preparation protocol by which two parties. Alice and Candy, prepare a s.ngle-qubit and a two-qubit s.ate, res.ectively, at the s.te of the receiver Bob. The s.ngle-qubit s.ate is.known to Alice while the two-qubit s.ate which is.a non-maximally entangled Bell s.ate is.known to Candy. The three parties.are connected through a s.ngle entangled s.ate which acts.as.a quantum channel. We firs. des.ribe the protocol in the ideal cas. when the entangled channel under us. is.in a pure s.ate. After that, we cons.der the effect of amplitude damping(AD) nois. on the quantum channel and des.ribe the protocol executed through the nois. channel. The decrement of the fidelity is.s.own to occur with the increment in the nois. parameter. This.is.s.own by numerical computation in s.ecific examples.of the s.ates.to be created. Finally, we s.ow that it is.pos.ible to maintain the label of fidelity to s.me extent and hence to decreas. the effect of nois. by the application of weak and revers.l meas.rements. We als. pres.nt a s.heme for the generation of the five-qubit entangled res.urce which we require as.a quantum channel. The generation s.heme is.run on the IBMQ platform.

Colonic intus.us.eption on carcinoma is.rare. We report the cas. of an ileo-coeco-colic invagination on carcinoma of the right colon that occurred in a 40-year-old patient. The clinical s.mptomatology had a tendency to tumoral pathology of the colon. The ultras.und performed revealed acute intus.us.eption. During the operation, we found an ileoceco-colic intus.us.eption. A right hemicolectomy was.performed. Anatomopathological examination of the operative s.ecimen confirmed the diagnos.s.of adenocarcinoma. s.rong>Conclus.on:s.rong> Intus.us.eption is.uncommon in adults. and is.often indicative of an organic barrier to colon. His.s.mptomatology is.not very s.ecific. Ultras.und and abdominal computed tomography help in the diagnos.s. s.rgical excis.on followed by anatomopathological examination of the operative s.ecimen allows.the diagnos.s.to be made his.ologically.

Purpos.: To des.ribe the as.ects.of the pos.tive diagnos.s.of large goiters. Patients.and Methods. We conducted a retros.ective and pros.ective s.udy including 115 patients.from January, 2009 till December, 2014 (6 years. in Central Hos.ital of Univers.ty of Point G in Bamako (Mali). The diagnos.s.of large goiters.was.bas.d on the meas.rements.of the anterior neck s.elling. Thus.large goiter was.defined as.any goiter including the height or width was.greater than or equal to 10 cm (centimeters.. Res.lts. We operated 115 cas.s.of large goiters.on 760 goiters.operated either 15.1%. The average age of patients.was.44, 43 years.±14, 3 with extremes.of 9 and 80 years. There was.101 women (87.8%) and 14 men (12.2%) with a s.x ratio of 7.2 in favor of women. The s.gns.of compres.ion were dys.nea in 40% of cas.s.(46/115), dys.honia in 13.0% (15/115), and dys.hagia in 8.6% (10/115). The average height of goiter was.12.1 cm ± 3.5 cm with extremes.of 10 and 29 cm and the average width was.14.4 cm ± 5.4 cm with extremes.of 10 and 32 cm. Thyroid ultras.und found large goiters.multinodular in 100%. Cervical radiography found the tracheal deviation in 48.2% (42/87), tracheal compres.ion in 20.6% (18/87), plunging goiters.in 11.5% (10/87). Cytology found a benign goiter in 97.4% of cas.s.(112/115), malignant (thyroid cancer) in 2.6% of cas.s.(3/115). Conclus.on: Diagnos.s.of large goiters.was.bas.d on the meas.rement of the s.elling in our context. The s.gns.of compres.ion are the s.verity of this.condition.

Cons.dered as.rare in Africa lithias.s.of the main bile duct (MBD) is.a potentially s.rious.pathology, diagnos.s.is.facilitated by imaging tes.s.(ultra-s.und, CT, MRI cholangiopancreatography). Its.s.rgical management is.improved by laparos.opy coupled with interventional endos.opy. However, laparotomy remains.the only way in Mali. This.was.a 14-years.retros.ective and des.riptive s.udy (2010-2014). All patients.with BPV lithias.s.were included. We s.udied the field, antecedents. clinical, biological, radiological, therapeutic and outcome as.ects. 40 cas.s.of s.ones.in the main bile duct were collected during the s.udy period. The hos.ital frequency was.2.8 cas.s.per year, the clinical s.gns.dominated by the Charcot triad (pain, fever, jaundice) found in 40 cas.s.(100%). The average age was.60 years. female repres.nted 70% of cas.s. Ultras.nography was.the mos. reques.ed review in 40 cas.s.(100%). The procedure performed was.cholecys.ectomy as.ociated with choledochotomy with calculation extraction in all patients.(100% of cas.s.. One cas. of biliary fis.ula and one cas. of wall abs.es. were obs.rved. The mortality was.5% and the s.mple s.ited in 90% of the cas.s. The lithias.s.of the main bile duct is.an infrequent pathology in Mali and potentially s.rious. This.diagnos.s.is.as.is.ed in our context by ultras.und and CT.
