Prochlorperazine,Treatment for Acute Confusional Migraine

HEADACHE, Issue 3 2009
Rakesh Khatri MD
Acute confusional migraine is a rare migraine variant primarily seen in childhood that lacks standardized diagnostic criteria. Acute symptomatic treatment for this disorder has not been established. We report 2 patients having a total of 6 episodes of acute confusional migraine where the symptoms resolved with prochlorperazine with variable success. Intravenous prochlorperazine was highly effective in 3 out of 4 episodes. [source]

Genotypic antiretroviral drug resistance testing at low viral loads in the UK

HIV MEDICINE, Issue 8 2008
PA Cane
Background Antiretroviral drug resistance testing is recommended in HIV-1 infected patients failing therapy in order to inform treatment selection. Although guidelines and test manufacturers recommend a viral load of at least 500,1000 HIV-1 RNA copies/mL for genotypic resistance testing to be performed, prompt management of virological failure could benefit from testing at lower viral load levels. Methods Laboratories undertaking genotypic resistance testing were asked to provide figures for the number of resistance tests undertaken at viral loads <2000 copies/mL, the success rates of such tests and the extent of resistance detected, all stratified for viral load levels. Results Of the replies received, most laboratories were attempting resistance testing at viral loads below the recommended guidelines, with variable success and outcomes. Conclusions This audit of current practice in the UK for undertaking genotypic resistance tests at viral loads <1000 copies/mL highlights the widespread use of such testing outside the British HIV Association guidelines.

Neoadjuvant strategies for the treatment of locally advanced esophageal cancer,

JOURNAL OF SURGICAL ONCOLOGY, Issue 4 2010
John R. Hyngstrom MD
Abstract Patients with locally advanced esophageal carcinoma have consistently poor survival following surgery with associated high systemic and local-regional failure rates. Neoadjuvant therapeutic strategies have been employed in an attempt to improve outcome with variable success. Randomized trials of either neoadjuvant chemotherapy or chemoradiotherapy have shown conflicting results regarding survival and local-regional control. Future efforts should focus on identifying novel agents and targets to improve therapeutic efficacy. J. Surg. Oncol. 2010; 101:299,304. © 2010 Wiley-Liss, Inc. [source]

Microsatellite markers for the red band needle blight pathogen, Dothistroma septosporum

MOLECULAR ECOLOGY RESOURCES, Issue 5 2008
I BARNES
Abstract Twelve microsatellite markers were developed for population analyses of the fungal pathogen, Dothistroma septosporum. Intersimple sequence repeat polymerase chain reaction (ISSR-PCR) and an enrichment protocol (fast isolation by amplified fragment length polymorphism of sequences containing repeats [FIASCO]) were both used to identify 28 unique microsatellite regions in the genome. From 22 primer pairs designed, 12 were polymorphic. These markers, screened on two populations representing 42 isolates, produced 40 alleles across all loci with an allelic diversity of 0.09,0.76 per locus. Cross-species amplification showed variable success with Dothistroma rhabdoclinis and Mycosphaerella dearnessi and some sequence variation within isolates of Dothistroma pini. These markers will be used to further study the population structure and diversity of D. septosporum. [source]

Beyond the High-Performance Paradigm?

BRITISH JOURNAL OF INDUSTRIAL RELATIONS, Issue 1 2001
An Analysis of Variation in Canadian Managerial Perceptions of Reform Programme Effectiveness
Proponents of the high-performance paradigm often argue that the variable success of new forms of work organization is explained primarily by a failure to implement them comprehensively and to adopt complementary HRM practices. This paper argues that these explanations are inadequate and develops an alternative, political economy approach which accounts more fully for how conflicts embedded in the employment relation limit the effectiveness of reforms. It draws on a unique longitudinal data set representing 78 Canadian workplaces to analyse the extent to which reform programme content, pre-existing HRM conditions and workplace context variables are associated with reform programme effectiveness.

Right ventricular involvement in hypertrophic cardiomyopathy: A case report and literature review

CLINICAL CARDIOLOGY, Issue 1 2001
Dariush Mozaffarian M.D.
Abstract Although hypertrophic cardiomyopathy (HCM) is classically considered a disease of the left ventricle, right ventricular (RV) abnormalities have also been reported. However, involvement of the right ventricle in HCM has not been extensively characterized. The literature regarding prevalence, genetics, patterns of involvement, histologic findings, symptoms, diagnosis, and treatment of RV abnormalities in HCM is reviewed. To highlight the salient points, a case is presented of apical HCM with significant RV involvement, with an RV outflow tract gradient and near obliteration of the RV cavity, in the absence of a left intraventricular gradient. Right ventricular involvement in HCM appears to be as heterogeneous as that of the left ventricle. The spectrum extends from mild concentric hypertrophy to more unusual severe, obstructive disease. While in some cases the extent of RV involvement correlates with left ventricular (LV) involvement, predominant RV disease can be seen as well. While the genetics of RV involvement have not been well characterized, histologic findings appear to be similar to those in the left ventricle, suggesting similar pathogenesis. Significant RV involvement may result in RV outflow obstruction and/or reduced RV diastolic filling, with potentially increased incidence of severe dyspnea, supraventricular arrhythmias, and pulmonary thromboembolism. The optimal treatment for patients with significant RV disease is unknown. Medical and surgical therapies have been attempted with variable success; experience with newer techniques such as percutaneous catheter ablation has not been reported. Further characterization of RV involvement in HCM is necessary to elucidate more clearly the clinical features and optimal treatments of this manifestation of HCM. [source]
