Arthropods at different stages of development collected from human remains in an advanced stage of decomposition (following autopsy) and from the soil at the scene are reported. The corpse was found in a mixed deciduous forest of Biscay (northern Spain). Soil fauna was extracted by sieving the soil where the corpse lay and placing the remains in Berlese-Tullgren funnels. Necrophagous fauna on the human remains was dominated by the fly Piophilidae: Stearibia nigriceps (Meigen, 1826), mites Ascidae: Proctolaelaps epuraeae (Hirschmann, 1963), Laelapidae: Hypoaspis (Gaeolaelaps) aculeifer (Canestrini, 1884), and the beetle Cleridae: Necrobia rufipes (de Geer, 1775). We confirm the importance of edaphic fauna, especially if the deceased is discovered in natural environs. Related fauna may remain for days after corpse removal and reveal information related to the circumstances of death. The species Nitidulidae: Omosita depressa (Linnaeus, 1758), Acaridae: Sancassania berlesei (Michael, 1903), Ascidae: Zerconopsis remiger (Kramer, 1876) and P. epuraeae, Urodinychidae: Uroobovella pulchella (Berlese, 1904), and Macrochelidae: Glyptholaspis americana (Berlese, 1888) were recorded for the first time in the Iberian Peninsula.

We report on a clinicopathological case of multiple system atrophy with good response to levodopa and subsequent development of motor complications. Because the subject complied with all the inclusion criteria (Core Assessment Program for Surgical Interventional Therapies in Parkinson's Disease), bilateral subthalamic nucleus deep brain stimulation electrodes were implanted.

Catheter-related bacteraemia (CRB) is a cause of death in hospitalized patients, and parenteral nutrition (PN) is a risk factor. We aim to describe the prognosis of PN-CRB and the impact of catheter extraction within 48 h from bacteraemia. All consecutive hospitalized adult patients with CRB (2007-2012) were prospectively enrolled. Factors associated with 30-day mortality were determined by logistic regression analysis. Among 847 episodes of CRB identified, 291 (34%) episodes were associated with short-term catheter use for PN. Cure was achieved in 236 (81%) episodes, 42 (14.5%) patients died within the first 30 days, 7 (2.5%) relapsed, and 6 (2%) had re-infection. On multivariate analysis, previous immunosuppressive therapy (OR 5.62; 95% CI 1.69-18.68; p 0.0048) and patient age (OR 1.05; 95% CI 1.02-1.07; p 0.0009) were predictors of 30-day mortality, whereas catheter removal within 48 h of bacteraemia onset (OR 0.26; 95% CI 0.12-0.58; p 0.0010) and adequate empirical antibiotic treatment (OR 0.36; 95% CI 0.17-0.77; p 0.0081) were protective factors. Incidence of PN-CRB decreased from 5.36 episodes/1000 days of PN in 2007 to 2.9 in 2012, yielding a 46.1% rate reduction (95% CI 15.7-65.5%), which may be attributable to implementation of a multifaceted prevention strategy. In conclusion, short-term PN-CRB accounted for one-third of all episodes of CRB in our setting, and 14.5% of patients died within 30 days following bacteraemia. Our findings suggest that prompt catheter removal and adequate empirical antibiotic treatment could be protective factors for 30-day mortality. Concomitantly with implementation of a multifaceted prevention strategy, PN-CRB incidence was reduced by half.
