Growth curves for normal Jamaican neonates.
The aim of this study was to provide standards for the assessment of birthweight, head circumference and crown-heel length for normal, singleton newborns of predominantly West African descent. Data were collected for 10 482 or 94% of all recorded births in Jamaica during the two-month period September 1 to October 31, 1986. After editing procedures, data were available for 6178 (birthweight), 5...
متن کاملAppendiceal MALT Lymphoma in Childhood – Presentation and Evolution
Lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma) was first described by Isaacson et al. in 1983 (Isaacson & Wright, 1984). According to the WHO lymphoma classification, the indolent B cell lymphoma of MALT type is classified as a marginal zone lymphoma, thus called because it originates from the B lymphocytes normally present in a distinct anatomical location (marginal zone) of the...
متن کاملNeed for new reference curves for height.
Data from the National Study for Health and Growth, on children aged from 4.0 to 12.0 years measured in 1972, 1985, and 1986 were used to assess whether new growth standards are required, and which subgroups of children might require separate standards. The change over this period, from just over half a centimetre in the youngest girls to over a centimetre in the oldest boys, warrants the use o...
متن کاملBayesian growth curves using normal mixtures with nonparametric weights
Reference growth curves estimate the distribution of a measurement as it changes according to some covariate, often age. We present a new methodology to estimate growth curves based on mixture models and splines. We model the distribution of the measurement with a mixture of normal distributions with an unknown number of components, and model dependence on the covariate through the weights, usi...
متن کاملCurves of constant diameter and inscribed polygons
If one drops the unicity assumption, (C(D)) is the property of having constant diameter, which is in fact equivalent (for closed curves in the plane) to having constant width or constant breadth (for the definitions and the proof of the equivalence, see [8, chap. 25]). It is a surprise to many (including me !) that curves of constant diameter other that the circle do exist. The simplest example...
