Resection of a plantar calcaneal spur using the holmium:yttrium-aluminum-garnet (Ho:YAG) laser.

Many procedures have been described for the resection of plantar calcaneal spurs as treatment of heel spur syndrome and chronic plantar fasciitis. Most of these techniques involve a medial incision of between 2 and 6 cm for adequate exposure of the calcaneal spur. This article describes a new technique for resecting a calcaneal spur with a smaller medial incision using the holmium:yttrium-aluminum-garnet (Ho:YAG) laser. This laser permits adequate resection of a plantar calcaneal spur as well as coagulation of the bone and surrounding tissues. This minimally invasive procedure has been used with good results over the past year by the senior author (W.K.S.) for the resection of calcaneal spurs.

[Strategy for monitoring and implementing methods for correcting child growth and development in rural areas of Sonora. Mexico].

An appropriate health technology to facilitate child growth and development in a rural area is presented and documented. Because mother's adequate behavior related to child's care does not produce immediate behavioral or physical changes it is necessary to create a long term social system of consequences. This was achieved joining a longitudinal measurement system with a program to train mothers to identify and deal with health and development issues. During four years, data were collected on weight-length development and morbidity twice a year and simultaneously skills were taught to diagnose treatment and prevent growth and development problems. After the third session child development and anthropometry data became the base of a system to assess maternal behavior, providing consequences for links in the behavior chains associated with child care. This system made organization and participation of the community in primary health care programs more likely, which implied a better score in each child growth and development chart.

Dye affinity adsorbent replacement optimization.

A method to determine the optimal replacement time for dye affinity adsorbents used in protein purification processes that are subjected to severe regeneration conditions has been developed. To demonstrate the utility of the method, an experimental fixed-bed decay model was employed to determine the optimum number of cycles for the adsorbent replacement. This number is a function of the column regeneration frequency and of the capital and operation costs. The implications of the results on the design and operation of dye-ligand chromatographic processes are discussed.
