Estudio anatómico de la hiperostosis porótica en órbitas oculares: cribra orbitalia en la población arqueológica de Tutuquén, región del Maule, Chile / Anatomical study of porotic hyperostosis in the eye orbits: cribra orbitalia in the archaeological population of Tutuquén, Maule region, Chile

RESUMEN: La cribra orbitalia o hiperostosis porótica del techo orbitario es considerada una manifestación ósea microperforativa de condiciones patológicas hematológicas, especialmente la anemia ferropénica. Este hallazgo, se enmarca de manera casi exclusiva a estudios en poblaciones arqueológicas. El propósito de este estudio fue describir la expresión de cribra orbitalia en una población arqueológica de Chile central. Restos óseos de 32 individuos fueron analizados, los cuales fueron obtenidos de la población del Monumento Arqueológico Cementerio Tutuquén, los que están depositados en el Museo Regional de Rancagua. En cada una de la muestras incluidas, se evaluaron períodos de datación, sexo, rango etáreo, presencia v/s ausencia de cribra orbitalia y en los casos en que ésta estuvo presente, se determinó su intensidad mediante visión directa con lente de aumento. Un 59,38 % de los individuos presentó cribra orbitalia. De éstos, 26,32 % fueron de sexo femenino, 31,58 % de sexo masculino y 42,10 % indeterminado. De los individuos del período 10.000 AP, 33,33 % presentó cribra orbitalia; de los individuos del período 7.000 AP un 50 % y de los individuos pertenecientes al período 1.000 AP, un 68,4 %. Al clasificar la severidad de la cribra orbitalia se observó que 31,57 % de los individuos presentaron Cribra orbitalia tipo I; 36,84 % tipo II; 10,52 % tipo III; 10,52 % tipo IV y 10,52 % tipo V. Los datos aportados complementarán el conocimiento morfopatológico de la órbita ocular humana desde el estudio de poblaciones arqueológicas.

SUMMARY: The cribra orbitalia or porotic hyperostosis of the orbital roof is considered a microperforative bone manifestation of hematological pathological conditions, especially iron deficiency anemia. This finding is almost exclusively part of studies in archaeological populations. The purpose of this study was to describe the expression of cribra orbitalia in an archaeological population of central Chile. Bone remains of 32 individuals were analyzed, which were obtained from the population of the Tutuquén Cemetery Archaeological Monument, which are deposited in the Regional Museum of Rancagua. In each of the included samples, dating periods, sex, age range, presence v / s absence of cribra orbitalia were evaluated and in the cases in which it was present, its intensity was determined by direct vision with a magnifying lens. The 59.38 % of the individuals presented cribra orbitalia. Of these, 26.32 % were female, 31.58 % male, and 42.10 % undetermined. Of the individuals in the period 10,000 BP, 33.33 % presented cribra orbitalia; of the individuals of the period 7,000 AP, 50% and of the individuals belonging to the period 1,000 AP, 68.4 %. When classifying the severity of the cribra orbitalia, it was observed that 31.57 % of the individuals had type I; 36.84 % type II; 10.52 % type III; 10.52 % type IV and 10.52 % type V. The data provided will complement the morpho-pathological knowledge of the human eye orbit from the study of archaeological populations.

Criba Orbitalia (hiperostosis porótica) en una población prehistórica del Paraná medio / [Cribra orbitalia (Porotic hyperostosis) in a prehistoric population of Parana Medio]

The observation of porotic hyperostosis in the orbits (criba orbitalia) in bone remains of a funeral site at the north of the Santa Fe province strongly suggests the occurrence of severe anemia among dwellers. Intestinal parasitosis (by Ancylostoma duodenalis or Necator americanus) is deemed the most likely cause of the anemia.

Primary ectopic meningioma.

Primary ectopic meningiomas are rare. A case of a 16-year-old male who presented with a large mass in temporofrontal region is reported. X-ray skull showed soft tissue shadow with hyperostosis of frontal and temporal bone. CT scan of brain demonstrated a markedly enhancing lesion and bony hyperostosis with no intracranial component. Total excision of tumour with hyperostotic bone was done. Patient is well without any evidence of recurrence two years after surgery. Relevant literature is reviewed.
