RESUMEN
The placement of an inferior vena cava (IVC) filter is a therapeutic method for selected patients with deep venous thrombosis and pulmonary embolism. However, insertion and placement of the filter may be associated with certain complications. For instance, retroperitoneal hematoma resulting from perforation of the wall by the filter is such a very rare but serious complication. We report the case of a 64-year-old woman with perforation of the IVC wall and consecutive hematoma caused by the filter who was treated surgically.

This paper reports on the effect of sonication on two mica samples. The materials have been investigated in terms of structure modifications, particle size and morphology, specific surface area and thermogravimetric behaviour. The effect of the mica structure, namely density and distribution of cations over the octahedral sites, on the sonicated products is reported. Sonication produces delamination and reduction of lateral size of the original macroscopic materials yielding nanometric flakes that retain the structure of the material, unlike other procedures previously reported in literature, such as dry grinding, that produces severe structural damage.

In an 82-year-old female diabetic tuberculosis involved the maxilla, zygomatic region, maxillary sinus and facial skin. No other foci of tuberculosis were found in the organism. The diagnosis and treatment are described stressing the extreme rarity of this involvement by tuberculosis.

It was demonstrated that exogenous GH suppressed the resistance to L. monocytogenes infection in Listeria resistant C57Bl/6 and susceptible A/J mice. However, different parameters of the immunological reaction to Listeria were affected by GH treatment in these mouse strains. In C57Bl/6 mice GH decreased accumulation of macrophages at the inflammatory site. On the contrary, a depression of anti-listerial activity of the phagocytes and a reduction of DTH reaction to Listeria antigen was demonstrated in GH treated A/J mice.

Relatively Listeria-resistant C57B1/6 mice and more susceptible to the infection DBA/2 mice were immunized with Listeria-antigen (LA). Immunized DBA/2 mice developed weaker delayed hypersensitivity to LA and still eliminated listeriae less effectively than identically immunized C57B1/6 mice. An accessory function of LA-pulsed macrophages of normal C57B1/6 mice was only slightly enhanced as compared with LA-pulsed macrophages of DBA/2 mice. It is suggested that some suppressor lymphocytes, IgM+ and/or FcR+, could be responsible for the enhanced susceptibility of DBA/2 mice to listeriosis.
