Posterior cortical atrophy: review of the recent literature.

Posterior cortical atrophy (PCA) is a group of neurodegenerative dementing disorders characterized by initial predominant visual complaints followed by progressive decline in cognitive functions. The visuospatial and visuoperceptual defects arise from the dysfunction of, respectively, the dorsal (occipito-parietal) and the ventral (occipito-temporal) streams. Clinical symptoms, results of neuropsychological examination, and findings of posterior cerebral atrophy and/or posterior hypoperfusion/hypometabolism contribute to the diagnosis. However, owing to the insidious onset of PCA and the non-specificity of initial symptoms, the diagnosis is often delayed. Specific etiologies include Alzheimer's disease, dementia with Lewy bodies, subcortical gliosis, corticobasal degeneration, and prion-associated diseases. Alzheimer's disease accounts for at least 80 % of PCA cases. Recent research has concentrated on better defining the clinical presentation of PCA, improving neuroimaging analysis, testing new neuroimaging techniques, and developing biological measurements. Selected recent papers on PCA are reviewed in this article.

Resolution of foveal detachment in dome-shaped macula after treatment by spironolactone: report of two cases and mini-review of the literature.

Dome-shaped macula (DSM) was recently described in myopic patients as a convex protrusion of the macula within a posterior pole staphyloma. The pathogenesis of DSM and the development of associated serous foveal detachment (SFD) remain unclear. The obstruction of choroidal outflow and compressive changes of choroidal capillaries have been proposed as causative factors. In this paper, we report two cases of patients with chronic SFD associated with DSM treated with oral spironolactone. After treatment, there was a complete resolution of SFD in both patients. To the best of our knowledge, this is the first report of successful treatment of SFD in DSM by a mineralocorticoid receptor antagonist.

Dual transplant of marginal kidneys. Case report and review of the literature.

INTRODUCTION: Double transplantation is one possible answer to the shortage of donor organs. While each donor kidney would be unsuitable when considered as a single allograft, use of both kidneys should provide sufficient nephron mass for effective glomerular filtration. CASE REPORT: This is the first Swiss report of a dual adult transplant of marginal kidneys in a 46-year-old man, who was transplanted for the fourth time. Follow-up at 6 months is excellent without acute rejection. CONCLUSION: Recent analysis of dual marginal versus single ideal transplant outcomes, found a comparable 1-yr graft survival in both of the procedures. Long term results are still lacking and guidelines to decide between single, double or no transplantation are emerging.

Vom Finanz- zum Wissenschaftsbetrug : Methode, den Irrungen in der medizinischen Literatur beizukommen [From financial to scientific fraud : Methods to detect discrepancies in the medical literature].

Fraud is as old as Mankind. There are an enormous number of historical documents which show the interaction between truth and untruth; therefore it is not really surprising that the prevalence of publication discrepancies is increasing. More surprising is that new cases especially in the medical field generate such a huge astonishment. In financial mathematics a statistical tool for detection of fraud is known which uses the knowledge of Newcomb and Benford regarding the distribution of natural numbers. This distribution is not equal and lower numbers are more likely to be detected compared to higher ones. In this investigation all numbers contained in the blinded abstracts of the 2009 annual meeting of the Swiss Society of Anesthesia and Resuscitation (SGAR) were recorded and analyzed regarding the distribution. A manipulated abstract was also included in the investigation. The χ(2)-test was used to determine statistical differences between expected and observed counts of numbers. There was also a faked abstract integrated in the investigation. A p<0.05 was considered significant. The distribution of the 1,800 numbers in the 77 submitted abstracts followed Benford's law. The manipulated abstract was detected by statistical means (difference in expected versus observed p<0.05). Statistics cannot prove whether the content is true or not but can give some serious hints to look into the details in such conspicuous material. These are the first results of a test for the distribution of numbers presented in medical research.

Female Genital Mutilation/Cutting - A Literature Review

This report represents the result of two different strands of work by the Women's Health Council. At the beginning of 2006, due to the recent significant inward migration experienced in Ireland, the Council's board identified the promotion of the health of ethnic minority women as a key area of work in its strategic plan for the period 2007-2009. At the same time, it was also decided that the problem of gender-based violence would also be addressed through a number of research and policy initiatives. This report focuses on a health issuethat marries these two concerns, Female Genital Mutilation/Cutting (FGM/C – see below for definition) and serves as an accompanying document to the recently published Violence Against Women and Health (2007) and the forthcoming study on Ethnic Minority Women and Gender-Based Violence.

Discovery of amino acid variants in the human glucose-dependent insulinotropic polypeptide (GIP) receptor: the impact on the pancreatic beta cell responses and functional expression studies in Chinese hamster fibroblast cells.

The two incretins, glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1), are insulinotropic factors released from the small intestine to the blood stream in response to oral glucose ingestion. The insulinotropic effect of GLP-1 is maintained in patients with Type II (non-insulin-dependent) diabetes mellitus, whereas, for unknown reasons, the effect of GIP is diminished or lacking. We defined the exon-intron boundaries of the human GIP receptor, made a mutational analysis of the gene and identified two amino acid substitutions, A207 V and E354Q. In an association study of 227 Caucasian Type II diabetic patients and 224 matched glucose tolerant control subjects, the allelic frequency of the A207 V polymorphism was 1.1% in Type II diabetic patients and 0.7% in control subjects (p = 0.48), whereas the allelic frequency of the codon 354 polymorphism was 24.9% in Type II diabetic patients versus 23.2% in control subjects. Interestingly, the glucose tolerant subjects (6% of the population) who were homozygous for the codon 354 variant had on average a 14% decrease in fasting serum C-peptide concentration (p = 0.01) and an 11% decrease in the same variable 30 min after an oral glucose load (p = 0.03) compared with subjects with the wild-type receptor. Investigation of the function of the two GIP receptor variants in Chinese hamster fibroblasts showed, however, that the GIP-induced cAMP formation and the binding of GIP to cells expressing the variant receptors were not different from the findings in cells expressing the wildtype GIP receptor. In conclusion, amino acid variants in the GIP receptor are not associated with random Type II diabetes in patients of Danish Caucasian origin or with altered GIP binding and GIP-induced cAMP production when stably transfected in Chinese hamster fibroblasts. The finding of an association between homozygosity for the codon 354 variant and reduced fasting and post oral glucose tolerance test (OGTT) serum C-peptide concentrations, however, calls for further investigations and could suggest that GIP even in the fasting state regulates the beta-cell secretory response.

Prehistoric tuberculosis in America: adding comments to a literature review

Tuberculosis is a prehistoric American human disease. This paper reviews the literature and discusses hypotheses for origins and epidemiological patterns of prehistoric tuberculosis. From the last decades, 24 papers about prehistoric tuberculosis were published and 133 cases were reviewed. In South America most are isolated case studies, contrary to North America where more skeletal series were analyzed. Disease was usually located at the deserts of Chile and Peru, Central Plains in USA, and Lake Ontario in Canada. Skeletal remains represent most of the cases, but 16 mummies have also been described. Thirty individuals had lung disease, 19 of them diagnosed by the ribs. More then 100 individuals had osseous tuberculosis and 26 also had it in other organs. As today, transmission of the infection and establishment of the disease were favored by cultural and life-style changes such as sedentarization, crowding, undernutrition, use of dark and insulated houses, and by the frequency of interpersonal contacts. The papers confirm that despite previous perceptions, tuberculosis seems to have occured in America for millennia. It only had epidemiological expression when special conditions favored its expansion. Occurring as epidemic bursts or low endemic disease, it had differential impact on groups or social segments in America for at least two millennia.

Cardiovascular health and wellbeing in Northern Ireland - Literature review

The PHA, supported by the Institute of Public Health in Ireland (IPH) and other agencies and individuals, has completed a health impact assessment (HIA) on the Cardiovascular Service Framework (CVSFW) for Northern Ireland.The CVSFW is the first in a series of service frameworks developed in Northern Ireland to guide HSC provision from prevention and health improvement over early intervention in communities and general practice into hospital and other institutional settings towards rehabilitation, palliative care and end of life.The CVSFW is relevant to everyone who has a part in HSC services for health improvement, hypertension, hyperlipidaemia, diabetes, heart disease, cerebrovascular disease (stroke), peripheral vascular disease and renal disease. This includes patients, carers, families, communities, voluntary and statutory service providers, policy makers and researchers.

What's in your Chinese Takeaway?

The impact that food prepared outside of the home has on the nutrient intakes of adults, has beenstudied previously on the IOI. It was found that food prepared outside the home contains considerably more dietary fat than food prepared within the home and it is also lower in fibre and micronutrients. safefood has commissioned previous nutritional surveys in the takeaway sector.These surveys revealed that certain foods i.e. potato, chicken, pizzas and burgers prepared outside thehome are high in calories, fat and salt. These surveys also reported that there are majordifferences in portion sizes across takeaway outlets on the IOI. Traditional Asian diets are low in fat and high in fruit, vegetables and fibre. However, thesetraditional meals have been adapted to suit Western palates and, in doing so, different ingredients indifferent quantities are added, possibly increasing their fat and salt content. Recent research hasfound that Chinese is the single most popular style of meal across both takeaways and restaurants(excluding pub restaurants) on the IOI. Given the diversity of Chinese dishes available, this surveywas designed to provide an insight into the energy (calorie), total fat, saturated fat, protein and saltcontent of a range of Chinese meals from various Chinese takeaways, and Chinese restaurants with atakeaway service.

Intérêt des faibles doses de rt-PA dans les syndromes inflammatoires et hémorragiques du segment antérieur: étude clinique et revue de la littérature [Treatment of anterior segment fibrinous reactions and hemorrhage with intracameral low dose rt-PA: clinical study and review of the literature].

PURPOSE: to evaluate the efficacy and the safety of low dose intraocular tissue plasminogen activator (rt-PA) in the treatment of traumatic hyphema and postoperative fibrinous membrane. METHODS: Six microg to 10 microg of rt-PA was injected into the anterior chamber to treat severe fibrinous postoperative membranes and total traumatic hyphemae. RESULTS: Thirteen eyes of 13 patients were treated. Four cases of traumatic hyphema and 9 cases of fibrinous membranes were included. Complete fibrinolysis within 24 hours was observed in 4 cases (30.8%). A partial success was noted in 7 eyes (53.8%). No beneficial effect was observed in two cases of traumatic hyphema associated with intravitreal hemorrhage after penetrating trauma. No side effect attributable to rt-PA occurred. CONCLUSION: Low dose intraocular rt-PA appears to be safe and effective in the treatment of postoperative fibrinous membrane and endocular hemorrhage limited to the anterior chamber.

A Review of Harm Reduction Approaches in Ireland and Evidence from the International Literature

This report examines international literature on harm reduction and also presents primary research in health services in Ireland on approaches to harm reduction. The aim of harm reduction efforts is to minimise the risks stemming from shared use of drug-use paraphernalia, such as needle exchange programmes. One of the criticisms of Irish drug services is that the restricted opening hours and limited number of exchange services may contribute to continued sharing of needles among drug users. The report points out that other non-injecting paraphernalia such as spoons are also associated with the risk of contracting diseases, yet services do not as yet focus on them. The report notes that specific risk factors that contribute to risky drug practices include youth, a shorter injecting history, confinement to prison, homelessness and being involved in a sexual relationship with another intravenous drug user. The report suggests that harm reduction practices can be introduced into a prison population without a subsequent increase in drug consumption rates. The provision of consumption rooms and the prescription of heroin are also discussed, with the report noting that legislation would have to altered to implement these new strategies.This resource was contributed by The National Documentation Centre on Drug Use.
