PURPOSE To find out whether nuchal cord causes an effect on the nuchal skin fold thickness (NFT) measurements, or not. PATIENTS AND METHODS A total of 242 fetuses with normal outcomes that had undergone detailed second trimester US scan between 18 and 24 weeks of gestation were included in the study. NFT measurements were made on axial cranial US images passing through the cerebellum and cavu...

Effect of height on F-wave latency: Redefining reference values for Iranian population

Intrudaction: F-wave latency is one of the most sensitive parameters which is used for diagnosis of radiculopathy and neuropathy in electrodiagnostic medicine. Electrodianosis professionals mostly use reference values published in major textbooks mostly written in USA based on anthropomorphic characteristics of American people. Also there is considerable difference between heights of males an...

Lung function reference values in Iranian adolescents.

There is insufficient information about reference values for pulmonary volumes for Iranian populations. A study of lung function parameters was made on 302 non-smoking healthy Iranian students (152 male and 150 female). Lung function measures correlated strongly with height but not with body mass index. There were significant differences between some of the measured parameters and American Thor...

Hematological indices in an older population sample: derivation of healthy reference values.

Factors affecting hematological values were explored, and healthy reference values were estimated from a cross-sectional survey of a population (n = 4433), ages 49 years or more, residing permanently in a defined geographic region. Nursing home residents were excluded. Details of medication use and medical history were obtained by interview, and participants were asked to return after an overni...
