Parvovirus B19-induced acute bilateral carpal tunnel syndrome in twin girls

We describe 2 cases of 6-year-old twin girls presenting with acute carpal tunnel syndrome (CTS) associated with human parvovirus B19 (HPV-B19) infection, as evidenced by serological data and detection of HPV-B19 DNA in blood with use of polymerase chain reaction (PCR). To our knowledge, this is the first time that HPV-B19 infection has been suggested as the causal agent of simultaneous acute bilateral CTS in twins, thus presenting the possibility that similar immunologic responses can be observed in twins during viral infections

Parathyroid Hormone Levels in the Prediction of Ischemic Stroke Risk

Objective. It was examined whether PTH and 25-dihydroxyvitamin D(25(OH)D) levels, together or separately, are indicators of the risk of stroke. Materials and Methods. This prospective study was performed at two centers. In the study, 100 patients diagnosed with acute ischemic stroke and 100 control individuals in the same age range were examined. In addition to neurological examination, cranial imaging, extensive routine blood chemistry, PTH, and 25(OH) D levels were evaluated in all cases. Stroke risk factors were determined. Logistic regression was used for statistical analysis. Results. A total of 60 patients and 79 control individuals were included in the study. Different estimation models were designed in order to examine the relationship between PTH and 25(OH) D levels with stroke. According to modeling results, it was determined that the most effective predictor for risk of stroke was 25(OH) D levels, followed by hypertension and PTH levels, respectively. Conclusion. PTH and 25(OH) D levels together can make important contributions to determination of stroke risk, and further investigations are needed to understand this relationship more fully
