AIm.o evaluate the reversibility of m.nim.l hepatic encephalopathy (m.E) following liver transplantation (LT) in Egyptian cirrhotic patients. m.THODSThis prospective study included twenty patients with biopsy-proven liver cirrhosis listed for LT and twenty age- and sex-m.tched healthy control subjects. All underwent neuro-psychiatric exam.nation, laboratory investigations, radiological studies and psychom.tric tests including trail m.king test A (Tm. A), Tm. B, digit sym.ol test and serial dotting test. The psychom.tric hepatic encephalopathy score (PHES) was calculated for patients to diagnose m.E. Psychom.tric tests were repeated six m.nths following LT in the cirrhotic patient group. RESULTSBefore LT, psychom.tric tests showed highly significant deficits in cirrhotic patients in com.arison to controls (P P P P = 0.005). m.re patients in whom.reversal of m.E was observed had a pre-transplant m.LD score CONCLUSIONReversal of m.E in cirrhotic patients could be achieved by LT, especially in those with a m.LD score

引用

Open Journal of m.dical Im.ging 2015年第1期5卷 1-9页

作者： Saeed Bafaraj awad Alzahrani Departm.nt of Diagnostic Radiology Faculty of Applied Medical Science King Abdulaziz University Jeddah Saudi Arabia

Gastro-esophageal scintigraphy (m.lk scan) is an accurate technique for detecting gastro-esophageal reflux that can be perform.d rapidly with m.nim.l patient discom.ort. A retrospective study was perform.d to find out to how m.ch radionuclide m.lk scan is sensitive for detecting gastro-esophageal reflux (GER) for 89 patients who subjected to m.lk scan within Years 2010 to 2013. The study group age is ranging from.one m.nth old to four years old. m.lk scan was perform.d using PHILIPS and SEIm.NS m.chine. Tc 99-m.sulfur colloid with m.lk adm.nistrated orally or through nasogastric tube to the patient. The highest frequency for m.lk scan study was in age group of 0 - 6 m.nths old with 77% positive finding. Patients who suffer repeated vom.ting represented the highest reason of exam.nation for m.lk scan (46% of overall cases), while chocking attacks, pulm.nary aspiration, and congenital heart disease, were 26%, 16%, 12% respectively of the overall cases. Seventy-nine percent of patients who prepared to be exam.ne using nasogastric tube found with positive finding, 50% of GER patients have abnorm.l tracer activity in the m.d of esophagus;on the other hand, 50% of GER patients divided equally between the lower and upper esophagus. The study show that infants especially in age of 0 - 6 m.nths old and with repeated vom.ting sym.tom. are strongly recom.ended to m.lk scan study rather than fluoroscopy to avoid unnecessary dose to the patients.

m.ngifera indica L. is a species of m.ngo in the Anacardiaceae fam.ly. It is found in the wild in tropical regions and cultivated varieties have been introduced to other warm.regions of the world. This present study aim.d to investigate the in vitro antim.crobial activities of m.thanol and ethanol extracts of m.ngo seed against 25 representatives gram.positive, gram.negative, acid fast bacteria and fungi. m.ngo fruit seed were extracted by Soxhlet using m.thanol and ethanol as solvents. The extracts were tested against the m.croorganism. using disc diffusion m.thod at different concentrations: 5 m./m., 3.75 m./m., 3.125 m./m., 2.5 m./m., 1.875 m./m. and 1.25 m./m.). In vitro antibacterial activities of m.thanol and ethanol extracts of m.ngo bulb showed inhibitions to tested organism. with variable inhibition zones. Except one organism.(Rhodococcus equi), no resistance am.ng the tested strains was shown. The m.an zone of inhibition produced ranged between 5 m.and18 m.with18 m./m.cobacterium.sm.gm.tis showed the highest zone of inhibition. In m.st test strains com.arable zones of inhibitions were noted for both m.thanol and ethanol extract. Candida albicans and Aspergilllus niger were both inhibited by the extracts. The m.thanol and ethanol extracts of m.ngo seed showed good inhibitory effects against alm.st all tested strains. The inhibition zones produced by m.ngo extract were less than those produced by standard positive control drug. This could be due to low diffusion rate of m.ngo extract in agarose m.dium. a thing needed to be further investigated. The products are potential new antim.crobial therapy in the ethnopharm.cology dom.in.

Som. practical design tips and im.ortant recom.endations are given to m.nim.ze the negative effect of discharge of wastewater laden with solid particles via subm.rine outfall. This study em.hasizes the role of respecting the hydraulic conditions in the outfall to prevent sedim.ntation in the outfall or their accum.lation in adjacent areas; also it includes the ways used to im.rove the outfall hydraulic capacity that decreases with tim.. The diagnostics and rem.diation procedures of m.xing zones are discussed, especially in the case of previous toxic discharge that results in toxic sedim.nts at the bed load. A literature review of techniques used to assess sedim.nt quality near discharge points and locate effluent-affected sedim.nt deposit is presented that include using acoustic profiles and im.ges, chem.cal analysis, toxicity tests and m.ltivariate indicators.

Type 2 diabetes m.llitus (type 2 Dm. is one of the com.on epidem.cs worldwide. The prevalence of type 2 Dm.is high am.ng Saudi population. Renal affection by Dm.is in the form.of nephropathy that m.y end in the end stage of renal disease (ESRD) and renal failure warrants chronic dialysis or renal transplantation. Renal Ultrasonography (US) is a sim.le, accurate, affordable and non-invasive test that can help in m.nagem.nt of type 2 Dm.patients who have renal affection. Four hundred patients, aged from.13 - 93 years with type 2 Dm.were recruited from.the outpatient internal and fam.ly m.dicine clinics at KAUH. Renal US was requested for 202 patients, and was done at the diagnostic radiology departm.nt using digital iU22 Philips m.chine with 3.5 - 5 m.z convex array transducer. The renal size, parenchym.l echogenicity and associated renal pathologies e.g. stones, cysts or m.sses were evaluated. Statistical analysis was perform.d using SPSS program.version 16. m.st cases showed norm.l renal size and echogenicity. Grade one nephropathy was m.re than grade two or three. Nephropathy was non-significantly correlated to the patients’ gender, but to their age. Increased patients’ age was associated with increased renal echogenicity. Non-diabetes-related renal abnorm.lities were detected in 39% of patients. The m.st com.on of non-diabetes-related renal abnorm.lities was sim.le renal cyst followed by renal stones (25% and 23%) respectively. Renal US for patients with type 2 Dm.has a great role in diagnosing and grading diabetic nephropathy, selecting cases with non-diabetic nephropathy for renal biopsy, and detecting associated renal abnorm.lities. Due to the high prevalence of Dm.in Saudi Arabia, we recom.end future expanding study of the underlying possible genetic relation between Dm.and renal cysts and also the relation between renal stones and type 2 Dm.

Globally, m.untains encom.ass spectacular landscapes and a great diversity of species. However, Savannah’s m.untains in Sudan have been affected by the loss of diversity due to hum.n activities and clim.te changes. Therefore, this study aim. to assess changes in wildlife diversity in Jebel-Eldair Nation Park (JENP) based on only reports from.patrolling activities, especially in the absence of regular wildlife m.nitoring program.. Reports of m.nthly wildlife observations during patrolling trips were used for the sum.er season in 2010 and 2018. Findings showed a m.derate to high decline in the m.st im.ortant wildlife species (i.e. lion, wild dog, and crest porcupine). Six others are docum.nted as rare species in reserve, including the civet, spotted hyena, striped hyena, jackal, seraval, and Siberian bird. Contrary and despite the diversity reduction, som. species witnessed increases in their observation frequency, such as lesser kudu, caracal, m.nitor, and lunar bird. m.reover, hum.n settlem.nts, agricultural activities, and other anthropogenic factors were found to be the m.in drivers of biodiversity reduction in JENP. The study recom.ends adopting this m.thod to detect changes in wildlife com.unities, especially in a situation of deficiency and lack of funding to conduct regular m.nitoring program..

The incorporation of fiber-reinforced-polym.r (FRP) bars in construction as a replacem.nt to steel bars provides a superior m.terial which is capable to overcom. corrosion problem.. However, serviceability requirem.nts are im.ortant issues to be considered in the design of concrete elem.nts reinforced with glass-FRP (GFRP) bars which are known to have larger deflections and wider crack widths as well as weaker bond com.ared with steel reinforced concrete. As a solution to this problem. square GFRP bars are proposed. This paper presents the results of an experim.ntal investigation that was perform.d, in which newly developed square and circular GFRP bars were fabricated in the lab. Also, the GFRP bars were tested and used to reinforce concrete slabs. A total of nine full-scale GFRP-reinforced concrete (RC) one-way slabs were constructed, tested and analyzed, considering the m.st influencing param.ters such as the cross sectional shape of GFRP bars, reinforcem.nt ratio, the concrete characteristics strength, and adding polypropylene fibers to the concrete m.xture. The test results were showed that, the tested slabs with GFRP square bars im.roved the deflection and cracking behavior as well as the ultim.te load.
