Study design:Observational study with prospective and retrospective monitoring.Objective:To describe the epidemiological and demographic characteristics of traumatic spinal cord injury (TSCI), and to analyze its epidemiological changes.Setting:Unidad de Lesionados Medulares, Complejo Hospitalario Universitario A Coruña, in Galicia (Spain).Methods:The study included patients with TSCI who had been hospitalized between January 1995 and December 2014. Relevant data were extracted from the admissions registry and electronic health record.Results:A total of 1195 patients with TSCI were admitted over the specified period of time; 76.4% male and 23.6% female. Mean patient age at injury was 50.20 years. Causes of injury were falls (54.2%), traffic accidents (37%), sports/leisure-related accidents (3.5%) and other traumatic causes (5.3%). Mean patient age increased significantly over time (from 46.40 to 56.54 years), and the number of cases of TSCI related to traffic accidents decreased (from 44.5% to 23.7%), whereas those linked to falls increased (from 46.9% to 65.6%). The most commonly affected neurological level was the cervical level (54.9%), increasing in the case of levels C1–C4 over time, and the most frequent ASIA (American Spinal Injury Association) grade was A (44.3%). The crude annual incidence rate was 2.17/100 000 inhabitants, decreasing significantly over time at an annual percentage rate change of −1.4%.Conclusions:The incidence rate of TSCI tends to decline progressively. Mean patient age has increased over time and cervical levels C1–C4 are currently the most commonly affected ones. These epidemiological changes will eventually result in adjustments in the standard model of care for TSCI.Spinal Cord advance online publication, 14 February 2017; doi:10.1038/sc.2017.13. © 2017 International Spinal Cord Society

Acinetobacter baumannii produces different types of infections including pneumonia, meningitis, and bloodstream infections. The optimal treatment of these infections has been complicated by the global emergence of multidrug resistant strains, requiring the development of novel approaches for treatment and prevention. Outer membrane vesicles are outpouchings of the bacterial outer membrane that are secreted from numerous pathogenic Gram-negative bacteria. In the present study, we describe the isolation of outer membrane vesicles from A. baumannii and their use as a vaccine in a mouse model of disseminated sepsis. Immunization produced a robust antibody response against multiple bacterial antigens which consisted of antigen-specific IgG and IgM. In addition, both IgG1 and IgG2c subtypes were produced by immunization. Immunized mice had lower tissue bacterial loads and lower serum levels of the pro-inflammatory cytokines IL-6 and IL-1β post-infection compared to control mice. Importantly, vaccination protected mice from challenge with the ATCC 19606 strain and provided protection against two clinical isolates, including a pan-resistant strain. These results indicate that vaccination with outer membrane vesicles may be a viable strategy for preventing A. baumannii infection. © 2011 Elsevier Ltd.

Objective: The Pecs block (pectoral nerves block) is an easy and reliable superficial block inspired by the infraclavicular block approach and the transversus abdominis plane blocks. Once the pectoralis muscles are located under the clavicle the space between the two muscles is dissected to reach the lateral pectoral and the medial pectoral nerves. The main indications are breast expanders and subpectoral prosthesis where the distension of these muscles is extremely painful. Material and methods: A second version of the Pecs block is described, called ''modified Pecs block'' or Pecs block type II. This novel approach aims to block at least the pectoral nerves, the intercostobrachial, intercostals III-IV-V-VI and the long thoracic nerve. These nerves need to be blocked to provide complete analgesia during breast surgery, and it is an alternative or a rescue block if paravertebral blocks and thoracic epidurals failed. This block has been used in our unit in the past year for the Pecs I indications described, and in addition for, tumorectomies, wide excisions, and axillary clearances. Results and conclusions: The ultrasound sequence to perform this block is shown, together with simple X-ray dye images and gadolinium MRI images to understand the spread and pathways that can explain the benefit of this novel approach. © 2012 Sociedad Española de Anestesiología, Reanimación y Terapéutica del Dolor.
Breast segments: A model for the prevention of deformities in conservative surgery for breast cancer. [Los segmentos mamarios. Un modelo para la prevención de deformidades en la cirugía conservadora del cáncer de mama]

Conservative breast cancer surgery requires an exact knowledge on the impact that local resection may have on the cosmetic result, and for this reason, the characteristics of each breast region must be taken into account. The segmentation theory helps to predict the consequences of local resection in each breast segment and, at the same time, optimise the choice of the best procedure for their prevention. Therefore, surgical planning based on segmentation of the breast would help us achieve a current objective of breast oncological surgery: a surgery adapted to the breast and the tumour. This article describes the different breast segments, their resources and limits for remodelling, and the best technical options to prevent deformities in each one of them. © 2011 AEC.

Clostridium difficile is the most common cause of infectious diarrhea in adults healthcare institutions. Recent studies have shown an increase in the incidence, severity and recurrence of C. difficile infection (CDI). Factors associated with the patient and medical care provided contribute to establishing colonization and, in some cases, subsequent progression to symptomatic disease. The availability of new microbiological techniques has contributed greatly to improving care for these patients. A diagnostic algorithm is provided for cases in which CDI is suspected based on current evidence regarding the effectiveness of microbiological and radiological methods. In cases in which CDI is confirmed, the first and most effective measure is the withdrawal of any antibiotic treatment the patient is receiving, if possible. The antimicrobial treatment of CDI is based on three classic agents: metronidazole, vancomycin and teicoplanin, along with the recent addition of fidaxomicin. Patients presenting serious symptoms, in addition to appropriate support and monitoring measures, may require surgical treatment. Infection prevention and control strategies can interrupt the transmission mechanism. This manuscript reviews current evidence on the approach of this entity from a multidisciplinary point of view.

To evaluate the association between recreational drug use and diabetic ketosis (DK) and diabetic ketoacidosis (DKA) in our area. Retrospective examination of records from a 1,450 bed urban teaching hospital in Spain. All adult admissions for DK or DKA from January 1, 2005, to December 31, 2009 in our hospital were included. Demographic, exploratory (blood pressure, heart rate, respiratory rate), and analytical data (glucose, urea, creatinine, corrected Na+, K+, pH, HCO3- and HbA1c) at admittance were recorded. In 152 patients, 253 episodes of DK or DKA occurred. Screening for drug use was performed in 40.3% of the events; 20.6% of the episodes (n = 52) were shown to be substance abuse. Cocaine, followed by cannabis and alcohol, was the most frequently involved drug. Poly-substance abuse occurred in 67.3% of them. Comorbidities were present in 11.5 and 39.8% of the cases shown and not shown to be related to drug use (P = 0.00). Seventy percent of the patients who were at least once shown to have consumed drugs, and 15.9% of those who were never shown to have done so, were admitted more than once (P = 0.00). The frequency of recent drug misuse in patients presenting with DK or DKA was high. Substance abuse screening was frequently neglected. Adverse profile, most significantly in readmission to hospital, was found in the patients with positive drug findings. History taking in this context should routinely include questions on substance abuse, and toxicology screening may be worthwhile, particularly in those with the history of frequent readmissions. © 2010 Springer-Verlag.

We investigated the mechanism of carbapenem resistance in 10 Acinetobacter baumannii strains isolated from the United States and Mexico between 2005 and 2009. The detection of known metallo-β-lactamase or carbapenem-hydrolyzing oxacillinase (OXA) genes by PCR was negative. The presence of plasmid-encoded carbapenem resistance genes was investigated by transformation of A. baumannii ATCC 17978. Shotgun cloning experiments and sequencing were performed, followed by the expression of a novel β-lactamase in A. baumannii. Three novel OXA enzymes were identified, OXA-235 in 8 isolates and the amino acid variants OXA-236 (Glu173-Val) and OXA-237 (Asp208-Gly) in 1 isolate each. The deduced amino acid sequences shared 85% identity with OXA-134, 54% to 57% identities with the acquired OXA-23, OXA-24, OXA-58, and OXA-143, and 56% identity with the intrinsic OXA-51 and, thus, represent a novel subclass of OXA. The expression of OXA-235 in A. baumannii led to reduced carbapenem susceptibility, while cephalosporin MICs were unaffected. Genetic analysis revealed that blaOXA-235, blaOXA-236, and blaOXA-237 were bracketed between two ISAba1 insertion sequences. In addition, the presence of these acquiredβ-lactamase genes might result from a transposition-mediated mechanism. This highlights the propensity of A. baumannii to acquire multiple carbapenem resistance determinants. Copyright © 2013, American Society for Microbiology. All Rights Reserved.

Congenital pseudoarthrosis of the tibia (CPT) is an uncommon disease presenting a tibial nonunion since birth and frequently associated to neurofibromatosis type 1. Surgical management by wide excision of the pseudoarthrosis and sustitution of the defect with vascularized bone in an early stage has proven to be the most effective technique in terms of bone consolidation. We present a clinical case of a 22-month-old patient with CPT treated successfully by reconstruction with a free vascularized fibula graft with an excellent functional result.

Introduction: Hypocalcaemia, although usually transitory, is the most frequent complication after total thyroidectomy. Objective: To identify factors associated with a higher risk of hypoparathyroidism and related to aetiology and surgical procedure. Material and method: A total of 254 total thyroidectomies were analysed for the incidence of transitory or permanent hypocalcaemia based on the relationship with etiological and surgical factors. Results: Transient hypocalcaemia was present in 29.1% of the cases and permanent hypocalcemia was present in 4.7%. Postoperative hypocalcaemia was lower in patients with completion thyroidectomy than in patients that underwent total thyroidectomy in a single operation, 12% vs. 31%. Patients with Graves-Basedow disease developed postoperative hypocalcaemia in 50% of the cases. Mean recovery time of parathyroid function was 5.2 months, with 72.2% of the patients recovering before 6 months. Conclusions: Postoperative hypocalcaemia is a frequent complication of total thyroidectomy, but it is seldom permanent. Patients with Graves-Basedow disease have a higher incidence of postoperative hypocalcaemia and need closer follow-up. Postoperative calcium level analysis at 24 and 48. hours after surgery is not useful for rapid identification of patients at high risk of hypocalcaemia. © 2012 Elsevier España, S.L.

Objective Information about the distribution of proteins and the modulation that they undergo in the different phases of rheumatic pathologies is essential to understanding the development of these diseases. We undertook this study to demonstrate the utility of mass spectrometry (MS)-based molecular imaging for studying the spatial distribution of different components in human articular cartilage sections. Methods We compared the distribution of peptides and proteins in human control and osteoarthritic (OA) cartilage. Human control and OA cartilage slices were cut and deposited on conductive slides. After tryptic digestion, we performed matrix-assisted laser desorption ionization-imaging MS (MALDI-IMS) experiments in a MALDI-quadrupole time-of-flight mass spectrometer. Protein identification was undertaken with a combination of multivariate statistical methods and Mascot protein database queries. Hematoxylin and eosin staining and immunohistochemistry were performed to validate the results. Results We created maps of peptide distributions at 150-μm raster size from control and OA human cartilage. Proteins such as biglycan, prolargin, decorin, and aggrecan core protein were identified and localized. Specific protein markers for cartilage oligomeric matrix protein and fibronectin were found exclusively in OA cartilage samples. Their distribution displayed a stronger intensity in the deep area than in the superficial area. New tentative OA markers were found in the deep area of the OA cartilage. Conclusion MALDI-IMS identifies and localizes disease-specific peptides and proteins in cartilage. All the OA-related peptides and proteins detected display a stronger intensity in the deep cartilage. MS-based molecular imaging is demonstrated to be an innovative method for studying OA pathology. © 2013 by the American College of Rheumatology.
