Perceptions, Experiences and Expectations of Physicians Regarding the Role of the Pharmacist in an Iraqi Hospital Setting

Purpose: To investigate the perceptions, expectations, and experiences of physicians regarding hospital-based pharmacists in some Iraqi government hospitals.Methods: A cross-sectional study was conducted at four government hospitals in Baghdad and Erbil, Iraq from March to July 2012. A validated, self-administered questionnaire was hand-delivered to a random sample of 200 physicians. The questionnaire comprised four sections that probed the physicians' demographic characteristics as well as their perceptions of, expectations of, and experiences with hospital pharmacists.Results: Most participants (69.4 %) reported rarely interacting with pharmacists and that enquiring about the availability of medications was the main purpose (74.9 %) of any interactions. Physicians reported being comfortable with pharmacists preventing prescription error, treating minor illness, and suggesting prescription medication to physicians of 74, 75 and 67 %, respectively, but only 47 % were comfortable with pharmacists providing patient education. The perspective of physicians in Erbil differed from that of physicians in Baghdad (p < 0.05).Conclusion: Interactions between Iraqi physicians and pharmacists are still not optimal. Physicians are much more comfortable with traditional pharmacist functions than with the extended, patient-oriented pharmacy services currently being promoted. Great efforts are needed to enhance the Iraqi physician's attitude regarding the clinical services provided by pharmacists which in turn would result in more collaboration among healthcare professionals.Keywords: Physician, Pharmacist, Perception, Experience, Expectation, Patient-oriented, Pharmacy servic

Earthworm-assisted bioremediation of petroleum hydrocarbon contaminated soil from mechanic workshop

The use of earthworms (Eudrilus eugenia) for vermi-assisted bioremediation of petroleum hydrocarbon contaminated mechanic workshop soils was investigated. Parameters of interest where earthworm survival, microbial count and identification, carbon and nitrogen contents of the soil and total petroleum hydrocarbon content of the soil. Earthworm survival was found to be dependent on the concentration of petroleum hydrocarbon and nature of the mechanic workshop. The survival of the worms in the as-obtained mechanic workshop soil was much lower than the survival in mechanic workshop soil diluted with petroleum hydrocarbon free soil. Earthworm inoculation also resulted in lower soil C and N contents after 35 days of vermi-assisted bioremediation. After 35 days of treatment, earthworm inoculation effected a higher drop in total petroleum hydrocarbon contents as compared to the samples without worms, indicating that earthworms may be used as biocatalysts in the bioremediation process.Key words: Eudrilus eugeniae, total petroleum hydrocarbon, mechanic workshop soil

Computer Modeling of Platinum Reforming Reactors

Usually, the reformate that is leaving any stage of the platinum reforming reactors in terms of hydrocarbon composition is assessed by laboratory analysis. The ideal composition can only be tested through theoretical means, which in most cases is avoided because of long computation time involved. This paper, instead of using a theoretical approach has considered a computer model as means of assessing the reformate composition for three-stage fixed bed reactors in platforming unit. This is done by identifying many possible hydrocarbon transformation reactions that are peculiar to the process unit, identify the operating data, mathematically model and programme their reaction rate equations using QBasic language. In this article outlet product rate of 311363.59 kg/hr in the first, second and third reactor was obtained by modeling 275 m3/h inlet feed rate of Bayton Rouge Naphtha in the Kaduna Refinery. A manual or theoretical calculated value of 311145.22 kg/hr of outlet product rate was obtained showing a slight deviation of 0.9%.  The authors are convinced that the written computer model could be applied in the process unit because it is accurate and less time consuming

Assessment of Plasma Cystatin C among Sudanese Patients with Type II Diabetes Mellitus

Background: Cystatin C is mainly used as a biomarker of kidney function. It is freely filtered by glomerulus, and does not return to the blood stream or secreted by renal tubules. It has been suggested to be closer to the “ideal” endogenous marker.Objectives: To assess the plasma levels of cystatin c, creatinine clearance, blood HbA1C% and body mass index among Sudanese with type 2  Diabetes.Materials and methods: This is a case-control study conducted in diabetic centers in Khartoum state, Sudan, from March 2010 to November 2013. A total of 300 Sudanese patients with type2 diabetes (49% males and 51% females) as a test group, and 150 healthy subjects (48%males and 52%females) as a control group were enrolled in this study. Both groups were matched for gender and age. The plasma levels of Cystatin C, creatinine and blood HbA1c were measured using Nephelometry technique. Creatinine clearance was calculated for each participant. SPSS was usedfor analysis of data.Results: The means of the plasma levels of Cystatin C, HbA1c% and the body mass index (BMI) were significantly raised in the diabetic group  compared to the control group (p<0.05).There is significant moderate negative correlation between Cystatin C and creatinine clearance (r=0.69,p=0.015) in the diabetic group, and there is a significant strong positive correlation between the plasma levels of Cystatin C and HbA1c%(r=o.78, p=0.044).Conclusion: The present data indicates that among Sudanese patients with Type 2 Diabetes Mellitus, plasma levels of Cystatin C are significantly raised and has a significant strong positive correlation with glycated  haemoglobin % and a significant moderate negative correlation with creatinine clearance.Key words: Type 2 Diabetes, Cystatin C, Glycated Heamoglobin, Sudan

Heavy metal contamination of soil in mechanic workshops

The distribution of metal in soil from mechanic workshops around Zaria, Nigeria (Latitude: 11° 4' 0 N, Longitude: 7° 42' 0 E) was studied. The types of mechanic workshops considered were motorcycle, motorcar, truck/lorries and generator set. The soils were sampled in August 2010. The results indicated that there was an increase in the metal content of soil in all types of mechanic workshops. The heavy metal (nickel, copper, zinc, lead and arsenic) content of the soil was compared with recommended limits. The percentage composition of some of the heavy metals, in many of the samples, were found to be in excess of the considered set limit, particularly for lead for which the percentage of soil samples analyzed from motorcycle, motorcar, truck/lories and generator set mechanic workshops in excess of the considered recommended set limit was found to be 88.89, 100, 100 and 100% respectively. 11.1% of all the samples analyzed were found to contain arsenic in excess of recommended limit. Statistical analysis of the heavy metal content (one-way analysis of variance) indicated that the Zn and Pb contents of soil from mechanic workshops were not functions of the workshop type (P > 0.05) but the nickel and copper contents were found to be dependent on workshop type (P < 0.05).Keywords: Elemental analysis, Heavy metals, Mechanic workshop, Soil, Zari

Effect of imazapyr treated maize on Striga infestation and time of intercropping cowpea in Samaru, Nigeria

Two field experiments were conducted at the research farm of Institute for Agricultural Research (IAR) Samaru, Zaria during the 2011 cropping season, with the aim of determining the effect of imazapyr treated maize on Striga infestation and time of intercropping cowpea in Samaru, northern guinea savannah of Nigeria. There were two sets of experiments: the first experiment consisted of Six (6) hybrids (AS1128-1, AS1128-2, AS1128-3, AS1128-4, AS1128-6 and AS1128-8) of imazapyr resistant (IR) maize seeds treated with imazapyr chemical and intercropped with cowpea at 2, 4 and 6 weeks after sowing (WAS) of maize. The second experiment consisted of the same Six (6) hybrids of IR maize seeds but untreated and also intercropped with cowpea at 2, 4 and 6 WAS of maize. The experiments were laid out in a split plot design with time of intercropping cowpea as main plot and hybrid maize varieties as sub plot, and replicated three times. The cowpea variety used for the trial was IT97K-499-35. Among the treated IR-maize hybrids, only AS1128-1, AS1128-2, AS1128-3 and AS1128-4 germinated while for the untreated, all the six hybrids germinated. The grain yields per hectare of all the treated maize hybrids did not significantly differed whereas grain yields per hectare of the untreated maize hybrids AS1128-1, AS1128-2, AS1128-3 and AS1128-4 were significantly higher than the hybrid AS1128-8. The treated IR  maize hybrids exerted 100% control of Striga while the untreated supported Striga emergence. There was no visible damage symptoms observed on the cowpea intercropped with treated maize at all times of intercropping. It is therefore concluded that the IR-maize hybrids ASII28-1, ASII28-2, ASII28-3 and ASII28-4 should be used in the treated forms for the control of Striga. Moreover, the intercropping of cowpea with imazapyr treated maize can be carried out starting from 2 WAS of maize.Key words: Intercropping, imazapyr resistant maize (IR-maize), cowpea, Striga

Effect of earthworm inoculation on the bioremediation of used engine oil contaminated soil

The effect of earthworm (Eudrilus eugeniae) on the bioremediation of used engine oil contaminated soil, amended with poultry manure, was investigated. Investigation into the effect of initial concentration of used engine oil, in soil, for earthworm inoculated samples showed that the biodegradation rate of used engine oil contaminant increased with increasing initial concentration of used engine oil. For initial used engine oil concentration of 5, 10, 15 and 20 g/kg soil, the drop in total petroleum hydrocarbon was found to be -16.91, 20.82, 34.68 and 36.28% respectively after 42 days of treatment. Investigation into the effect of earthworm concentration showed that the use of earthworms did not result in catalysis of the bioremediation process as the extent of biodegradation for the sample without earthworm was found to be higher than those of all concentrations of earthworm considered (5 - 20 worms/kg soil). However, the rate of bioremediation was found to increase with increase in earthworm concentration (as earthworm concentration was increased from 5 to 20 worms per kg of used engine oil contaminated soil). Similarly when the rate of bioremediation in the without-earthworm but manually tilled and the without-earthworm and untilled samples where compared with samples inoculated with earthworm for bioremediation, both samples without worms recorded higher bioremediation rates.Keywords: Concentration, Time, Total petroleum hydrocarbon, vermicomposting, Eudrilus eugenia

Calciphylaxis following kidney transplantation: a case report

Introduction: Calciphylaxis occurring after kidney transplantation is rare and rarely reported. It results in chronic non-healing wounds and is associated with a poor prognosis and is often fatal. We present a case of proximal lower limb calciphylaxis that occurred early after kidney transplantation. The patient had no classic associated risk factors. He had previously had a total parathyroidectomy but had normal serum calcium-phosphate product and parathyroid hormone levels. The clinical outcome of this case was favorable and highlights some fundamental issues relating to management. Case prsentation: A 70-year-old British Caucasian man with end-stage renal failure secondary to IgA nephropathy presented six months post kidney transplantation with cutaneous calciphylaxis lesions involving the medial aspect of the thigh bilaterally. Conclusion: To the best of our knowledge, this is the first reported case of rapid onset cutaneous calciphylaxis occurring soon after kidney transplantation that was associated with a favorable outcome. Cutaneous calciphylaxis lesions should be promptly managed with meticulous wound care, antimicrobial therapy and the correction of calcium-phosphate product where indicated
