Pharmacy patron perspectives of community pharmacist administered influenza vaccinations

Background

One approach to boost influenza vaccination coverage has been to expand immunization authority. In 2012, the province of Ontario gave community pharmacists the authority to administer the influenza vaccine.

Toxicity of polycyclic aromatic hydrocarbons. III. Effects of beta-naphthoflavone pretreatment on hepatotoxicity of compounds produced in the ozonation or NO2-nitration of phenanthrene and pyrene in rats

Male Sprague-Dawley rats were treated ip with beta-naphthoflavone (BNF, 40 mg/kg/day) in dimethylsulfoxide (DMSO, 26.7 mg BNF/ml) for three days. At 24 hr after the pretreatment DMSO (3.0 ml/kg), phenanthrene (150 mg/kg), ozonized or nitrated products of phenanthrene (150 mg/kg), pyrene (150 mg/kg), or ozonized or nitrated products of pyrene (150 mg/kg) were injected ip. Phenanthrene, pyrene, and their ozonized or nitrated products were dissolved in DMSO (50 mg/ml). No increase in the level of aspartate aminotransferase (AST), alanine aminotransferase (ALT) or sorbitol dehydrogenase (SDH) was seen in the pretreated rats 48 hr after the treatment. This is in contrast to what was seen in previous work without the BNF pretreatment. BNF pretreatment induced a small but significant increase in gamma-glutamyl transpeptidase (GGTP) levels. No treatment group receiving BNF differed from another with respect to GGTP. A decrease in lactate dehydrogenase (LDH) levels was noted in the nitro-PAH treatment groups; the same phenomenon was observed earlier in rats treated with nitro-PAH without BNF treatment. These results suggest that the mixed-function oxidase systems specifically induced by BNF have a protective effect against the hepatotoxicity of the oxonized or nitrated products of phenanthrene and pyrene.     

Lexical judgments after right- or left-hemisphere injury

Patients with unilateral left- or right-hemisphere lesions were asked to make similarity judgments to visually presented words on the basis of rhyme, meaning or visual similarity. The left-hemisphere-injured group was significantly impaired, relative to controls, for all types of lexical judgments, with the greatest impairment in the rhyme condition. Patients with right-hemisphere injury were also impaired, but only when lexical judgments were based on meaning. The results are generally consistent with normal and split-brain lateralization findings, and provide evidence supportive of a right-hemisphere contribution to some aspects of lexical semantic processing.     

Colonoscopic diagnosis of an aorto-appendiceal fistula

A case of an aorto-appendicular, aorto-enteric fistula diagnosed by colonoscopy after presentation with colonic haemorrhage is reported. The role of colonoscopy in such patients is discussed and reported experience is reviewed.     

A novel G protein-coupled receptor kinase gene cloned from 4p16.3.

Within the Huntington's disease (HD) candidate region of 4p16.3, the D4S127 locus displays strong linkage disequilibrium with the defect and anchors a conserved haplotype found on many HD chromosomes. To isolate genes from this region we have applied the exon amplification technique to overlapping cosmids spanning D4S127. Here, we report the discovery of a new gene encoding a novel member of a family of protein kinases that specifically phosphorylate the activated forms of G protein-coupled receptors. Such kinases are thought to participate in desensitization of specific receptors, thereby blocking further signal transduction. This gene must now be carefully scrutinized to determine whether it might be involved in HD.     

Colonoscopy — how difficult,how painful?

Colonoscopy is sometimes painful for the patient and often difficult for the endoscopist, but it is hard to predict how difficult or painful the examination will be. The purpose of this study was to identify factors that influence difficulty and pain during colonoscopy.Some 1,284 consecutive patients undergoing office colonoscopy by three endoscopists were prospectively studied. A standard questionnaire was completed by the nursing staff, who assessed the degree of difficulty and pain associated with each exam on a four-point scale.There were 682 men and 551 women (sex not recorded in 51). There was no pain in 27%, mild pain in 39%, moderate pain in 25%, and severe pain in 9%. There was no difficulty in 25%, mild difficulty in 33%, moderate difficulty in 28%, and severe difficulty in 14%. Colonoscopy was significantly easier (P<0.001, chi square) and less painful (P<0.001, chi square) in patients after sigmoidectomy. It was more painful after hysterectomy (P<0.05, chi square) and more difficult and painful in women than in men (P<0.01, chi square). There were significant differences between endoscopists in the assessment of pain associated with colonoscopy.Most colonoscopies are associated with little or no pain (66%) and are easy or only mildly difficult to perform (58%). Patients who have had sigmoid resection are especially easy and painless to examine while women, especially after hysterectomy, are at higher risk of having a painful experience. Colonoscopy technique can influence the amount of pain experienced by the patient.     

Assignment of the lens intrinsic membrane protein MP19 structural gene to human chromosome 19.

We have isolated and characterized a bovine cDNA clone encoding the bovine lens intrinsic membrane protein, MP19. This cDNA was used as a probe to analyze a panel of Southern blots of human-Chinese hamster somatic cell hybrid DNAs to assign the gene coding for MP19 to its human chromosome. Control human and Chinese hamster DNAs displayed a distinct EcoR1 restriction fragment pattern when hybridized with the bovine MP19 cDNA. When somatic cell hybrid DNAs were restricted with Eco R1 and Southern blots hybridized with the bovine MP19 cDNA, the characteristic human restriction pattern was observed only when human chromosome 19 was present in the hybrid panel. This assignment was confirmed using a human chromosome 19-specific genomic library. A clone from this human chromosome 19-specific library was identified and further characterized. This clone contained a 7.9 kilobase fragment that contained identical DNA sequences with that of the authentic bovine MP19 cDNA, and with a separate human genomic clone containing the MP19 gene.
