Progressive supranuclear palsy (PSP) is characterized by slowness, rigidity, bradykinesia, repeated falls, downgaze limitation and dementia. Midbrain atrophy on magnetic resonance imaging is highly suggestive of PSP and is described as "hummingbird sign". This sign is very helpful in differentiating PSP patients from those with Parkinson's disease. We hereby report a 72-year-old female case of PSP primarily diagnosed with Parkinson's disease.

This study was performed to evaluate the impact factors (IFs) and total citations of ISI-indexed nutrition journals in a 10-year period from 1999 to 2008 in order to assess the quality of nutrition journals. ⋯ The IF illustrated changes in relative rankings of five highly cited journals included in the "nutrition and dietetics" category of the Web of Knowledge. Rank according to the absolute number of citations received, however, did not correlate with rank according to IF.

There is an association of celiac disease (CD) with several gastrointestinal illnesses. We aimed to determine the prevalence of CD in patients with inflammatory bowel disease (IBD) to evaluate the value of the routine serological tests for CD in these patients. ⋯ the prevalence of serologic CD in general population in Iran has been reported to be 0.6-0.96%. Then, its prevalence in our sample size was about ten times more than that in general population.

Circulating endothelial cells (CECs) and E-selectin are known as sensitive and specific markers of endothelial dysfunction. This study investigated whether CECs and E-selectin are surrogate biomarkers of preeclampsia and if measurement of CECs and E-selectin, early in the third trimester, could be a means of predicting preeclampsia. ⋯ Higher levels of CECs and E-selectin in women with positive rollover test who developed preeclampsia prior to onset of the complication were predictive of preeclampsia. However, larger studies are needed to confirm these findings.

By providing a picture from published articles in a field, bibliometric studies can inform policy-makers in their challenging research funding decisions. In this regard, we applied bibliometric analysis to the Iranian pediatrics articles published in PubMed indexed journals between 1975 and 2007. ⋯ Contribution of Iran in production of pediatrics science is showing a sharp increase after 2002, this pattern is in parallel with other research fields.
