Effect of a Device-Free Compressed Shell Fixation Method on Hepatic Respiratory Movement: Analysis for Respiratory Amplitude of the Liver and Internal Motions of a Fiducial Marker

Purpose

Suppression of respiratory movement of the liver would be desirable for high-precision radiation therapy for liver tumors. We aimed to investigate the effect of our original device-free compressed shell fixation method and breathing instruction on suppression of respiratory movement. The characteristics of liver motion based on the movement of a fiducial marker were also analyzed.

Wound,pressure ulcer and burn guidelines – 4: Guidelines for the management of connective tissue disease/vasculitis-associated skin ulcers

The Japanese Dermatological Association prepared guidelines focused on the treatment of skin ulcers associated with connective tissue disease/vasculitis practical in clinical settings of dermatological care. Skin ulcers associated with connective tissue diseases or vasculitis occur on the background of a wide variety of diseases including, typically, systemic sclerosis but also systemic lupus erythematosus (SLE), dermatomyositis, rheumatoid arthritis (RA), various vasculitides and antiphospholipid antibody syndrome (APS). Therefore, in preparing the present guidelines, we considered diagnostic/therapeutic approaches appropriate for each of these disorders to be necessary and developed algorithms and clinical questions for systemic sclerosis, SLE, dermatomyositis, RA, vasculitis and APS.     

The clinical characteristics of Acinetobacter bacteremia differ among genomospecies: A hospital-based retrospective comparative analysis of genotypically identified strains

Background/purposeAcinetobacter is an aerobic, gram-negative coccobacillus, which causes nosocomial infections including bacteremia. Recent development of molecular techniques has made classification of the Acinetobacter genomospecies possible, but there are still only a few studies comparing clinical features of the subspecies. We investigated bacteremia caused by Acinetobacter, isolated subspecies, and compared clinical features for each group.MethodsA retrospective analysis of Acinetobacter bacteremia cases was made in a 900-bed hospital in Japan. In addition to conventional procedures, subspecies identification based on rpoB sequence was made, and comparison of clinical characteristics between each subspecies were analyzed.ResultsWe collected 35 cases (Acinetobacter baumannii 14, A. nosocomialis 12, Acinetobacter ursingii 6, and A. seifertii 3). All of the A. seifertii bacteremia cases were blood stream infection occurring in cerebrovascular disease patients, showing particularly higher incidence of shock (100%) and high Pitt bacteremia score (PBS) (6.33 ± 2.52) in comparison to A. baumannii (43% and 2.86 ± 2.25, respectively). Sequential Organ Failure Assessment (SOFA) score and the PBS were slightly higher in A. nosocomialis in comparison to A. baumannii, and the 7 day mortality rate was higher in A. nosocomialis (25%) than in A. baumannii (7%), though this difference was not found to be significant.ConclusionsA.seifertii, the recently defined novel species, showed distinctive clinical features of bacteremia. And, in contrast to previous studies, the severity of A. nosocomialis infection was not lower than that of A. baumannii, which might suggest the influence of local epidemiology. Further characterization of these subspecies should be continued.
