RESUMEN
Various diagnostic and therapeutic procedures of the right side of the heart and the systemic venous system have increased the need for ready access to the inferior vena cava (IVC) through the transfemoral route. Anatomical variations or obstruction of the IVC can make these procedures difficult. The case of 47 year old woman with an interrupted infrahepatic IVC with azygos continuation accompanied by sick sinus syndrome and a structurally normal heart is reported. Negotiating a temporary pacing lead from the IVC to the right atrium was difficult. Ultimately, the lead took the course from the IVC to azygos vein to superior vena cava to right atrium to right ventricular apex. Permanent VVI pacing through the right subclavian route was uneventful, as the superior vena cava and its tributaries had a normal course. An awareness of the existence of these anomalies before pacing can lead to the use of an alternative route for pacing, which may avoid undue delay of an otherwise urgently needed procedure.

We report a case of atypical lipomatous tumor-sclerosing type, a rare retroperitoneal soft tissue liposarcoma, presented with vague musculoskeletal symptoms. Patient was managed with complete resection of the tumor mass with adjuvant chemotherapy. The patient is doing well, with no evidence of recurrence 22 months after the treatment.

Antibodies were detected against bovine herpesviruses 1 (BHV 1) and 2 (BHV 2) in Asian elephants (Elephas maximus) using the passive hemagglutination (PHA) test. The study was conducted during May to December 1994 using sera collected from zoological gardens and national parks in India. Four (4%) of 109 elephant sera had PHA titers ranging from 1:8 to 1:32 against BHV 1. Twenty-five (23%) of the 109 elephant sera had PHA titers ranging from 1:8 to 1:64 against BHV 2. Asian elephants appear to be better reservoirs for herpesviruses which are serologically related to BHV 2.
