Tricobezoares

The objective of this article is to study the clinical presentation and diagnostic indexes for pediatric trichobezoars based on clinical cases and literature review. The abdominal tetrad of subacute pain, epigastric mass, ponderal loss and trichophagia strongly suggests the diagnosis of trichobezoar in pediatric patients. Behaviour problems are the rule, but there isn't always a previous psychiatric diagnosis. Treatment is surgical and psychiatric long-term follow-up is necessary

Soils of the Pampean Region

Pampean landscapes are characterized by the presence ofextensive plains originally covered by grasslands. At present,rainfed production of cereal and oil crops is the maineconomic farming activity of the region and constitutes ahigh proportion of Argentina exports. The most fertile soilsof Argentina are located in this region. They are Mollisols(mainly Argiudolls and Hapludolls), the most important andwidespread soil order in the region. Argiudolls are usuallyvery deep and show a complex profile, with highlydifferentiated horizons. Hapludolls have simpler profileswith surface layers occupied by coarser deposits. LocalMollisols were developed from loessic materials of predominantlysilty granulometry, with some involvement of sand,leading to very favourable natural soil physical conditionsfor crop growth. Other conspicuous soil orders are Entisolsand Alfisols. In this chapter, soil genesis and major soil typesare described and four subregions were considered: Northern,Western, Southern and Flooding Pampa.Fil: Rubio, Gerardo.
