Measurement of vertebral rotation: a comparison of two methods based on CT scans

Krismer,M.; Chen,A.M.; Steinlechner,M.; Haid,C.; Lener,M.; Wimmer,C.; This study compared Ho’s and Aaro’s method to measure vertebral axial rotation in order to find the more accurate one. Two hundred fifty-nine CT scans were taken from 11 cadaver vertebrae. The scans were performed with vertebrae in neutral position and angulated up to 20 degrees in the sagittal and frontal plane to simulate kyphosis/lordosis and side bending. Axial rotation was measured according to both methods. [Read More]

Pulmonary Aspergillus colonization in humans and its impact on management of critically ill patients

Lass-Florl,C.; Salzer,G.M.; Schmid,T.; Rabl,W.; Ulmer,H.; Dierichi,M.P.; Samples of lung tissues were obtained and analysed for Aspergillus carriage in 56 patients undergoing thoracic surgical intervention and 18 people who had an unexpected death. Out of 74 samples, 46 (63%) had evidence of pulmonary fungal colonization. The surgery population had a rate of 62% of fungal growth. Aspergillus was present in 39%. The autopsy population had a rate of 61% of fungal colonization. [Read More]

Quantitative determination of joint incongruity and pressure distribution during simulated gait and cartilage thickness in the human hip joint

von Eisenhart,R.; Adam,C.; Steinlechner,M.; Muller-Gerbl,M.; Eckstein,F.; The objective of this study was to provide quantitative data on hip-joint incongruity and pressure during a simulated walking cycle and on articular-cartilage thickness in the same set of specimens. Using a casting technique in eight specimens of the human hip (age: 18-75 years), we determined the width of the joint space (incongruity) required at minimal load for contact at four phases of the gait cycle.

Quantitative determination of pressure distribution in the hip joint during the gait cycle

von Eisenhart-Rothe,R.; Witte,H.; Steinlechner,M.; Muller-Gerbl,M.; Putz,R.; Eckstein,F.; The objective of this investigation was the experimental determination of the contact pressures in the hip joint for characteristic phases of the gait cycle. The joint forces determined in vivo with telemetric endoprosthesis by Bergmann et al. (1993) were converted into a pelvic reference system, based on kinematic gait analysis. In eight cadaveric hip joints (age 18-75 yrs.) the reaction forces were applied corresponding to four phases of the gait cycle (heel strike, mid-stance, heel off, toe off) and the pressure distribution determined with FUJI pressure sensitive film.

Results of collaborative study regarding the standardization of the Y-linked STR system DYS385 by the European DNA Profiling (EDNAP) group

Schneider,P.M.; D’Aloja,E.; Dupuy,B.M.; Eriksen,B.; Jangblad,A.; Kloosterman,A.D.; Kratzer,A.; Lareu,M.V.; Pfitzinger,H.; Rand,S.; Scheithauer,R.; Schmitter,H.; Skitsa,I.; Syndercombe-Court,; Vide,M.C.; Y-chromosome linked short tandem repeat (STR) loci are inherited as a closely linked haplotype, which appears to remain stable in a given paternal lineage over many generations. In forensic cases, Y-linked STRs are particularly useful for the identification of human remains as well as in rape cases with mixed male/female stain samples. DYS385 is derived from tandemly duplicated segments of the Y chromosome thus giving rise to two fragments of variable length which do not behave like alleles but genotypes. [Read More]
