[Frequency of footprints alterations in school children from a Mexican community].

Introduction: Alterations in the plantar footprint in the child are a cause for concern in parents.

Objective: Determine the frequency of plantar footprint alterations in school children. Determine if there is a relationship between overweight and obesity with the presence of alterations of the plantar footprint.

Incidence of Vertebral Fractures in Women with Systemic Lupus Erythematosus After 8 Years of Follow-Up.

The aim of this study was to evaluate possible associations between potential risk factors and the occurrence of established vertebral fractures (VF) in Mexican patients with systemic lupus erythematosus (SLE). Consecutive patients with SLE were enrolled in a prospective, observational study from 2006 to 2015. Information on potential risk factors, including demographics, clinical data, and bone mineral density (BMD) at the lumbar spine and hip on dual-energy X-ray absorptiometry was collected at baseline and follow-up.

Trisomy 6qter resulting from a familial (6;10) (q23;q26) translocation.

An infant deceased at 2 months of age was found to have a 46,XY,-10, +der(10),t (6;10) (q23;q26) mat karyotype. Since the clinical findings were similar to those of the trisomy 6qter syndrome, the present observation agrees with the assignment of the 6q23----qter segment as the pathogenetic determiner of this entity.

Whole-arm t(X;17) (Xp17q;Xq17p) and gonadal dysgenesis. A further exception to the critical region hypothesis.

A 19-year-old female patient with gonadal dysgenesis and a de novo t(X;17) (Xp17q;Xq17p) is described. Since the critical segment Xq13----q26 was intact, this case is a further exception to the critical region hypothesis.

Cortical blindness, growth and psychomotor retardation and postaxial polydactyly: a probably distinct autosomal recessive syndrome.

A 14-month-old female infant with a syndrome mainly consisting of cortical blindness, psychomotor retardation and postaxial polydactyly (type B in hands and type A in feet) was studied. Two deceased sibs were similarly affected. Differential diagnosis and the review of medical literature permit the individualization of a distinct syndrome with a probable autosomal recessive pattern of inheritance.

Tetrasomy 18p: a distinctive syndrome.

A 10-month-old girl with growth and psychomotor retardation and pyramidal signs, was found to have a 47,XX,inv(9)(p11q13),+i(18p) karyotype. Whereas the inverted chromosome was inherited from the father, the isochromosome was of unknown origin. A comparative analysis with 17 similar cases from the literature lead to the conclusion that the tetrasomy 18p actually constitutes a distinctive syndrome.
