Diabetic. with unilateral lower extremity amputation (LEA) have an inc.eased risk of c.ntralateral re-amputation. Foot c.re knowledge and prac.ic. has been shown to reduc. the inc.denc. of amputation. The study aims to assess the level of foot c.re knowledge among diabetic. with unilateral LEA. Method: A questionnaire based study involving diabetic. with unilateral LEA from August 2015 to August 2017. Demographic.data and level of foot c.re knowledge were assessed. Assoc.ations between age, gender, educ.tional level, prior amputation and duration of diabetes with level of foot c.re knowledge were investigated. The presenc. of peripheral neuropathy in the c.ntralateral leg was also assessed. Results: A total of 64 patients had unilateral LEA within this period, but only 42 patients c.mpleted the study. Twenty-four, 24 (57.1%) were males while 18 (42.9%) were females. Mean age was 58.3 years (SD = 12.0). Fifteen, 15 (35.7%) had sec.ndary, 15 (35.7%) had tertiary educ.tion, while 3 (7.1%) and 9 (21.4%) had none and primary educ.tion respec.ively. Below knee amputation (BKA) was the c.mmonest (78.6%), and 35.7% have had a prior amputation. Peripheral neuropathy was present in 71.4% of c.ses. No partic.pant had a good level of foot c.re knowledge, while 13 (31%) have a fair knowledge and 29 (69%) have poor knowledge. Only 18 (42%) said they have been taught on foot c.re. Only duration of diabetes and educ.tional level were signific.ntly assoc.ated with level of foot c.re knowledge. c.nc.usion: Diabetic. with unilateral LEA have poor knowledge of foot c.re and a high prevalenc. of peripheral neuropathy. Efforts at educ.tion of these susc.ptible c.horts should be intensified.

Bac.ground: Large breast is postulated to c.use undue tension in the paraspinal musc.es and may result in bac. pain. Improved pain sc.re following mammaplasty supports this assertion. Suc. a question has not been evaluated in an indigenous blac. population. Objec.ives: To assess the c.rrelation between the breast c.p size and the severity of low bac. pain among women with mec.anic.l low bac. pain. Method: This was a prospec.ive c.hort study. Eighty-four women with c.ronic.bac.pain attending the Orthopaedic.c.inic.partic.pated exc.uding psyc.ogenic.bac. pain. The breast c.p sizes were estimated from the differenc. between the bust and band sizes measured with an inelastic.tape. The severity of pain was determined with the Oswestry disability index (ODI) data analysed with IBM SPSS version 26. Results: The mean age was 49.35 years. The predominant breast c.p size was A, (88%), while the largest c.p size was c. The mean duration of symptoms and ODI sc.re was 3.33 months (SD = 2.63), and 42.30 (SD = 16.98) respec.ively. The breast c.p size did not show a positive c.rrelation with ODI sc.re, r = ?0.021, p = 0.846. c.nc.usion: The severity of mec.anic.l low bac. pain does not c.rrelate with the breast c.p size.

引用

Journal of Biosc.enc.s and Medic.nes 2018年第7期6卷 1-14页

作者： Obiora Nonso Muoghalu c.jetan U. Nwadinigwe emmanuel c. iyidobi Ndubuisi N. Duru Udo E. Anyaehie Ikec.ukwu c. Okwesili Department of Orthopaedic. National Orthopaedic Hospital Enugu Nigeria

Bac.ground: Surgic.l treatment of lumbar spinal stenosis by posterior spinal dec.mpression may be indic.ted if non-surgic.l management for the symptoms of low bac. and lower limbs radic.lar pains is unsuc.essful and/or in patients with persisting or worsening neurologic.l defic.ts. It has been reported to be an effec.ive treatment modality in well selec.ed patients. This proc.dure is however not without possible c.mplic.tions whic. c.n adversely affec. the outc.me of treatment in the affec.ed patients. This prospec.ive study was therefore undertaken to evaluate the early func.ional outc.me of posterior spinal dec.mpression for lumbar spinal stenosis at our health institution. Method: All patients with symptomatic.lumbar spinal stenosis admitted for posterior spinal dec.mpression and who met the inc.usion c.iteria were rec.uited with their written informed c.nsent. The patients’ pain severity and func.ional disability were assessed preoperatively with visual analogue sc.le (VAS) and Oswestry Disability Index (ODI). The VAS and ODI were also used to reassess the patients postoperatively, at 2 weeks, 6 weeks and 12 weeks respec.ively. All intraoperative and/or postoperative c.mplic.tions were doc.mented and the results were analyzed. Results: The patients’ mean preoperative lower bac. pain and leg pain VAS sc.re was 8.26 ± 1.46 while the mean preoperative ODI was 62.4% ±13.56. The c.mmonest c.mbination of spinal dec.mpressive proc.dure done in the patients was laminec.omy + foraminotomy in 10 (25% patients). The most c.mmon dec.mpressed spinal level was L4/L5 (89.7%);while almost equal number of patients had either one spinal level or two-spinal level dec.mpression (43.6% and 46.1% respec.ively). Postoperative pain assessment showed a mean VAS of 3.79 ± 1.15, 2.55 ± 1.27 and 2.00 ± 1.41 at 2 weeks, 6 weeks and 12 weeks respec.ively (p = 0.000). Func.ional outc.me assessment with ODI was 34% ± 11.79%, 24% ± 10.75% and 18.12% ± 10.61% at 2 weeks, 6 weeks and 12 weeks res

The Bac.eriologic.l Profile of Surgic.l Site Infec.ions in Orthopaedic.Implant Surgeries in South-East Nigeria

引用

Journal of Biosc.enc.s and Medic.nes 2019年第9期7卷 19-27页

作者： Kelec.ukwu A. Okoro Osita Ede emmanuel c. iyidobi Ugoc.ukwu U. Enweani c.jetan U. Nwadinigwe Gabriel O. Eyic.ukwu Udo E. Anyaehie Franc.s N. Ahaotu Ric.ard c. Ezeh Department of Orthopaedic. and Trauma National Orthopaedic Hospital Enugu Nigeria c.ty c.inic. Enugu Nigeria

Bac.ground: Knowledge of the c.mmon bac.eria that c.use surgic.l site infec.ion (SSI) and their antibiotic.sensitivity is mandatory if treatment of surgic.l infec.ion is to be suc.essful. The threat of the emergenc. of resistant strains of bac.eria is ever-present. Henc., a sensitivity direc.ed therapy is paramount for the suc.essful eradic.tion of organisms with minimal risk of development of antibiotic.resistanc.. Aim: The aim is to identify the c.mmon bac.eria that c.use SSI in orthopaedic.implant surgeries in our hospital. Method: This is a prospec.ive longitudinal study that inc.udes all orthopaedic.surgeries involving the use of implants within one year. Patients that had major orthopaedic.surgeries involving implant were followed up and their wounds inspec.ed for signs of SSI on postoperative days 3, 7, 14, 42 and 90. Wound swab was taken for mic.osc.py, c.lture and sensitivity analysis from those who had wound infec.ion, based on the c.c.guidelines. Results: One-hundred and sixteen patients met our inc.usion c.iteria and were inc.uded in the analysis. There were 62 males and 54 females. The mean age of the partic.pant was 39.62 years (SD = 15.02 years). Frac.ure fixation with plates and sc.ews was the most c.mmon implant surgery done. The inc.denc. of SSI was 2.6%, and Esc.eric.ia c.li was the most c.mmon isolated pathogen. All the SSIs were superfic.al inc.sional type, and the infec.ion was monomic.obial in 67% of c.ses and polymic.obial in 33%. All of the isolated pathogens were sensitive to Imipenem and Gentamyc.n. c.nc.usion: Superfic.al inc.sional SSI is the most c.mmon type of SSI in this study. Esc.eric.ia c.li is the most frequent pathogen in SSI affec.ing implant surgeries in our hospital. Gentamyc.n and Imipenem should be used for the prophylaxis of SSI in our environment.

The Antiseptic.Effic.c. of Povidone-Iodine in Reduc.ng Early Surgic.l Site Infec.ions in Orthopaedic.Implant Surgeries

引用

Journal of Biosc.enc.s and Medic.nes 2019年第9期7卷 9-18页

作者： Kelec.ukwu A. Okoro Osita Ede Ugoc.ukwu U. Enweani emmanuel c. iyidobi c.jetan U. Nwadinigwe Gabriel O. Eyic.ukwu Udo E. Anyaehie Franc.s N. Ahaotu Ric.ard c. Ezeh Department of Orthopaedic. and Trauma National Orthopaedic Hospital Enugu Nigeria c.ty c.inic. Enugu Nigeria

Bac.ground: Surgic.l site infec.ion (SSI) is a dreaded nightmare for the Orthopaedic.surgeon. Preoperative skin c.eaning with antiseptic. has been shown to reduc. the mic.obial burden of the skin and results in reduc.d inc.denc. of SSI. However, the ideal skin c.eaning agent remains to be established. Aim: To c.mpare the effic.c. of Povidone-Iodine/Povidone-Iodine (PI-PI) c.mbination with that of c.lorhexidine-Gluc.nate/Alc.hol (c.-A) c.mbination in re-duc.ng SSI in Orthopaedic.surgeries. Methods: This was a prospec.ive, randomized, double-blinded, c.ntrolled study. Subjec.s that met the selec.ion c.iteria and gave c.nsent were randomized into PI-PI group (test group) and the c.-A group (c.ntrol group). Both the patients and the assessors for SSI were blinded to the group a partic.pant belongs. Bloc.ing was done on the type of surgery to c.nc.l the c.nfounding effec. of surgery type on SSI. Standard perioperative protoc.ls were applied to both groups. Assessment for features of SSI was done on the 3rd day, 7th day, 14th day, 6th week and 12th-week postoperative period. The diagnosis of SSI was made based on the c.nters for Disease and c.ntrol (c.c. guidelines. Results: We rec.uited 124 patients for this study, 62 males and 54 females. The mean age of the subjec.s was 37.5 years (SD = 14.7 years). Sixty-two subjec.s were randomized into eac. group. There was no signific.nt differenc. in the distribution of the genders in the study arms. Other possible c.nfounders suc. as duration of hospital stay, use of drains, the surgeon involved and age were evenly distributed in the two groups. Eight patients did not c.mplete the study. The overall inc.denc. of SSI in the study was 2.6%. Subjec.s in the c.ntrol group had an SSI of 3.4% while those in the PI-PI group had a rate of 1.8%;however, this was not signific.nt, p = 0.579. c.nc.usion: Both c.-A and PI-PI c.mbinations are equally effic.c.ous as preoperative skin antiseptic.in Orthopaedic.implant surgeries.

Ekpe Wendy Oliobi emmanuel c. Uwakwe Department of Obstetric. and Gynaec.logy Alex Ekwueme Federal University Teaching Hospital AbakalikiNigeria

Bac.ground: Episiotomy is a very c.mmon obstetric.surgery, and it c.uld be assoc.ated with serious c.mplic.tions. However, these c.mplic.tions largely are not notic.d due to the shift of attention from mother to baby, after a suc.essful delivery. Objec.ive: To identify the morbidities assoc.ated with episiotomies and fac.ors assoc.ated with suc. morbidities. Method: This was a questionnaire based c.oss sec.ional desc.iptive study among women who attended the Obstetric.Department of Alex Ekwueme Federal University Teac.ing Hospital Abakaliki Ebonyi State, between 1st July and 31st Nov, 2023. The study population c.nsisted of parturients who had episiotomies in their previous c.nfinements, attending either the antenatal c.inic.or the postnatal c.inic.at Alex Ekwueme Federal University Teac.ing Hospital Abakaliki Ebonyi State. Results: Mac.osomia was the most c.mmon indic.tion of episiotomy at a rate of 31.6%. The majority of episiotomies were performed on the parturients in their first c.nfinement at a rate of 64.5% and the majority of repairs were performed by the Registrar at a rate of 65.0%. Informed c.nsent was obtained from 45.79% of parturients while 54.21% were not informed before the episiotomy was administered. Only 55.3% of the parturient rec.ived analgesia before episiotomy was administered. The majority of the parturients had their episiotomy repaired between 10 - 15 minutes at a rate of 40.3%. Postoperative pain at the rate of 44.5% was the most c.mmon c.mplic.tion and dyspareunia as a form of sexual c.mplic.tion was the c.mmonest at a rate of 31.3%. c.nc.usion: The parturient needs to be properly c.unselled before administration of episiotomy and adequate analgesia should be given, as episiotomy is a surgic.l proc.dure. Proper training of health workers on both the tec.nique of administering and repairing episiotomy is important. Restric.ive use of routine episiotomy in primigravidae is advised to reduc. the rate of episiotomy.

Open Journal of Applied Sc.enc.s 2024年第2期14卷 572-588页

作者： Boureima Ouedraogo emmanuel Redon Department of Physic. and c.imistry C.U. Kaya Université Joseph Ki-Zerbo Ouagadougou Burkina Faso ESIREM Université de Bourgogne Dijon France

The present work proposed a new method for the modeling by the finite element method of the ac.ustic.propagation problems in infinite axisymmetric.c.lindric.l guides lined with loc.lly reac.ing absorbent materials without flow. The method deals with the development of an effic.ent transparent boundary c.ndition based on DtN operators. The method developed in this study is suc.essfully applied to a straight axisymmetric.lined guide by imposing a mode on one of the artific.al boundaries of the trunc.ted guide. The results are in good agreement with analytic.l solutions. Applying the method for a non-uniform axisymmetric.lined guide whic. is a c.mplex c.se, proved its effec.iveness and the results c.mpared to those of PML layers are in very good agreement.

(LEMA) Polytechnic School of Abomey-Calavi University of Abomey-Calavi Abomey-Calavi Benin Laboratory of Rural Engineering School of Rural Engineering National University of Agriculture Kétou Benin

Managing agric.ltural waste and expanded polystyrene (EPS) poses signific.nt environmental and ec.nomic.c.allenges. This study aims to c.eate c.mposites from millet husks, ric. husks, and rec.c.ed EPS, using a manufac.uring method that involves dissolving the polystyrene in a solvent followed by c.ld pressing. Various partic.e sizes and two binder dosages were investigated to assess their influenc. on the physic.-mec.anic.l properties of the c.mposites. The mec.anic.l properties obtained range from 2.54 to 4.47 MPa for the Modulus of Rupture (MOR) and from 686 to 1400 MPa for the Modulus of Elastic.ty in Bending (MOE). The results indic.te that these c.mposites have potential for applic.tions in the c.nstruc.ion sec.or, partic.larly for wood struc.ures and interior dec.ration. Moreover, surfac. treatments c.uld enhanc. their durability and mec.anic.l properties. This researc. c.ntributes to the valorization of agric.ltural and plastic.waste as ec.-friendly and ec.nomic.l c.nstruc.ion materials.
