Abstract
INTRODUCTION A high number of patients with stroke develop upper extremity spasticity, causing abnormal postures and patterns. These alterations limit the use of arm in functional activities and affect social participation. AIM To determine the prevalence of spasticity and postural patterns of the upper extremity post stroke. MATERIALS AND METHODS A cross-sectional descriptive design was used with a prospective follow-up. The sample included 136 patients. The study included 3 measuring times; at 10 days (T1), applying a record with sociodemographic-clinical data, the evaluation of muscle tone in the elbow and wrist and the postural patterns of the UE, and at 3 months (T2) and 12 months (T3) post stroke, re-evaluating tone and patterns. Prevalence was calculated through the one-sample chi-squared (χ2) test followed by inspection of the standardized residuals (z) in each cell. The Kappa coefficient evaluated the degree of agreement in elbow and wrist tone. RESULTS The prevalence of spasticity in the elbow was 37.5% at T1, 57.4% at T2, and 57.4% at T3. At each time there was a high degree of agreement between elbow and wrist tone. Patients developed increased elbow tone between T1 and T2, with maintained tone between T2 and T3. Postural pattern III was the most prevalent according to Hefter's classification. CONCLUSION The prevalence of spasticity in the elbow and wrist increases between 10 days and 3 months post stroke, and is maintained between 3 and 12 months. The onset of spasticity occurs in almost half of patients during the first 10 days post stroke. Postural pattern III according to Hefter's classification presented the greatest prevalence in the spastic UE.

Abstract
BACKGROUND There is no proven specific pharmacological treatment for patients with the acute respiratory distress syndrome (ARDS). The efficacy of corticosteroids in ARDS remains controversial. We aimed to assess the effects of dexamethasone in ARDS, which might change pulmonary and systemic inflammation and result in a decrease in duration of mechanical ventilation and mortality. METHODS We did a multicentre, randomised controlled trial in a network of 17 intensive care units (ICUs) in teaching hospitals across Spain in patients with established moderate-to-severe ARDS (defined by a ratio of partial pressure of arterial oxygen to the fraction of inspired oxygen of 200 mm Hg or less assessed with a positive end-expiratory pressure of 10 cm H2O or more and FiO2 of 0·5 or more at 24 h after ARDS onset). Patients with brain death, terminal-stage disease, or receiving corticosteroids or immunosuppressive drugs were excluded. Eligible patients were randomly assigned based on balanced treatment assignments with a computerised randomisation allocation sequence using blocks of 10 opaque, sealed envelopes to receive immediate treatment with dexamethasone or continued routine intensive care (control group). Patients in the dexamethasone group received an intravenous dose of 20 mg once daily from day 1 to day 5, which was reduced to 10 mg once daily from day 6 to day 10. Patients in both groups were ventilated with lung-protective mechanical ventilation. Allocation concealment was maintained at all sites during the trial. Primary outcome was the number of ventilator-free days at 28 days, defined as the number of days alive and free from mechanical ventilation from day of randomisation to day 28. Secondary outcome was all-cause mortality 60 days after randomisation. All analyses were done according to the intention-to-treat principle. This study is registered with ClinicalTrials.gov, NCT01731795. FINDINGS Between March 28, 2013, and Dec 31, 2018, we enrolled 277 patients and randomly assigned 139 patients to the dexamethasone group and 138 to the control group. The trial was stopped by the data safety monitoring board due to low enrolment rate after enrolling more than 88% (277/314) of the planned sample size. The mean number of ventilator-free days was higher in the dexamethasone group than in the control group (between-group difference 4·8 days [95% CI 2·57 to 7·03]; p<0·0001). At 60 days, 29 (21%) patients in the dexamethasone group and 50 (36%) patients in the control group had died (between-group difference -15·3% [-25·9 to -4·9]; p=0·0047). The proportion of adverse events did not differ significantly between the dexamethasone group and control group. The most common adverse events were hyperglycaemia in the ICU (105 [76%] patients in the dexamethasone group vs 97 [70%] patients in the control group), new infections in the ICU (eg, pneumonia or sepsis; 33 [24%] vs 35 [25%]), and barotrauma (14 [10%] vs 10 [7%]). INTERPRETATION Early administration of dexamethasone could reduce duration of mechanical ventilation and overall mortality in patients with established moderate-to-severe ARDS.

Abstract
Dengue virus (DENV) has re-emerged in Europe driven by the geographic expansion of the mosquito species Aedes albopictus and Aedes aegypti (Diptera: Culicidae) and the introduction of the virus by viraemic travellers. In the present study, the vector competence (VC) of Ae. albopictus collected in Catalonia (northeast Spain) was evaluated for two different DENV strains, DENV-1 and DENV-2, the serotypes responsible for all outbreaks of dengue that have occurred in Europe. Mosquitoes were reared under environmental conditions mimicking the mean temperature and humidity recorded in July on the Mediterranean coast of Catalonia. Mosquitoes were fed on an artificial infectious bloodmeal and, at 14 days post-exposure, infection, disseminated infection and transmission rates (IR, DIR, TR) and transmission efficiency (TE) were determined by testing the virus in the body, legs and saliva. The tested Ae. albopictus strain was found to be susceptible to both DENV-1 and DENV-2 and to be able to transmit DENV-1. This is the first time that the VC of Ae. albopictus for DENV has been tested in Europe in this specific context (i.e. mimicking the Mediterranean temperature and humidity recorded in Catalonia in July). This study confirms the potential of Ae. albopictus to start autochthonous DENV transmission cycles in the Mediterranean basin.

Abstract
Rift Valley fever (RVF) is a mosquito-borne disease caused by the Rift Valley fever virus (RVFV). Rift Valley fever affects a large number of species, including human, and has severe impact on public health and the economy, especially in African countries. The present study examined the vector competence of three different European mosquito species, Culex pipiens (Linnaeus, 1758) form molestus (Diptera: Culicidae), Culex pipiens hybrid form and Stegomyia albopicta (= Aedes albopictus) (Skuse, 1894) (Diptera: Culicidae). Mosquitoes were artificially fed with blood containing RVFV. Infection, disseminated infection and transmission efficiency were evaluated. This is the first study to assess the transmission efficiency of European mosquito species using a virulent RVFV strain. The virus disseminated in Cx. pipiens hybrid form and in S. albopicta. Moreover, infectious viral particles were isolated from saliva of both species, showing their RVFV transmission capacity. The presence of competent Cx. pipiens and S. albopicta in Spain indicates that an autochthonous outbreak of RVF may occur if the virus is introduced. These findings provide information that will help health authorities to set up efficient entomological surveillance and RVFV vector control programmes.

Abstract
H7N9 virus infection is a global concern, given that it can cause severe infection and mortality in humans. However, the understanding of H7N9 epidemiology, animal reservoir species and zoonotic risk remains limited. This work evaluates the pathogenicity, transmissibility and local innate immune response of three avian species harbouring different respiratory distribution of α2,6 and α2,3 SA receptors. Muscovy ducks, European quails and SPF chickens were intranasally inoculated with 105 embryo infectious dose (EID)50 of the human H7N9 (A/Anhui/1/2013) influenza isolate. None of the avian species showed clinical signs or macroscopic lesions, and only mild microscopic lesions were observed in the upper respiratory tract of quail and chickens. Quail presented more severe histopathologic lesions and avian influenza virus (AIV) positivity by immunohistochemistry (IHC), which correlated with higher IL-6 responses. In contrast, Muscovy ducks were resistant to disease and presented higher IFNα and TLR7 response. In all species, viral shedding was higher in the respiratory than in the digestive tract. Higher viral shedding was observed in quail, followed by chicken and ducks, which presented similar viral titres. Efficient transmission was observed in all contact quail and half of the Muscovy ducks, while no transmission was observed between chicken. All avian species showed viral shedding in drinking water throughout infection.

Abstract
Background Although much has evolved in our understanding of the pathogenesis and factors affecting outcome of patients with acute respiratory distress syndrome (ARDS), still there is no specific pharmacologic treatment for ARDS. Several clinical trials have evaluated the utility of corticoids but none of them has demonstrated a definitive benefit due to small sample sizes, selection bias, patient heterogeneity, and time of initiation of treatment or duration of therapy. We postulated that adjunctive treatment of persistent ARDS with intravenous dexamethasone might change the pulmonary and systemic inflammatory response and thereby reduce morbidity, leading to a decrease in duration of mechanical ventilation and a decrease in mortality. Methods/design This is a prospective, multicenter, randomized, controlled trial in 314 patients with persistent moderate/severe ARDS. Persistent ARDS is defined as maintaining a PaO2/FiO2 ≤ 200 mmHg on PEEP ≥ 10 cmH2O and FiO2 ≥ 0.5 after 24 hours of routine intensive care. Eligible patients will be randomly allocated to two arms: (i) conventional treatment without dexamethasone, (ii) conventional treatment plus dexamethasone. Patients in the dexamethasone group will be treated with a daily dose of 20 mg iv from day 1 to day 5, and 10 mg iv from day 6 to day 10. Primary outcome is the number of ventilator-free days, defined as days alive and free from mechanical ventilation at day 28 after intubation. Secondary outcome is all-cause mortality at day 60 after enrollment.

Abstract
The emerging disease West Nile fever is caused by West Nile virus (WNV), one of the most widespread arboviruses. This study represents the first test of the vectorial competence of European Culex pipiens Linnaeus 1758 and Stegomyia albopicta (= Aedes albopictus) (both: Diptera: Culicidae) populations for lineage 1 and 2 WNV isolated in Europe. Culex pipiens and S. albopicta populations were susceptible to WNV infection, had disseminated infection, and were capable of transmitting both WNV lineages. This is the first WNV competence assay to maintain mosquito specimens under environmental conditions mimicking the field (day/night) conditions associated with the period of maximum expected WNV activity. The importance of environmental conditions is discussed and the issue of how previous experiments conducted in fixed high temperatures may have overestimated WNV vector competence results with respect to natural environmental conditions is analysed. The information presented should be useful to policymakers and public health authorities for establishing effective WNV surveillance and vector control programmes. This would improve preparedness to prevent future outbreaks.

Abstract
OBJECTIVE To describe the case-mix of patients admitted to intensive care units (ICUs) in Spain during the period 2006-2011 and to assess changes in ICU mortality according to severity level. DESIGN Secondary analysis of data obtained from the ENVN-HELICS registry. Observational prospective study. SETTING Spanish ICU. PATIENTS Patients admitted for over 24h. INTERVENTIONS None. VARIABLES Data for each of the participating hospitals and ICUs were recorded, as well as data that allowed to knowing the case-mix and the individual outcome of each patient. The study period was divided into two intervals, from 2006 to 2008 (period 1) and from 2009 to 2011 (period 2). Multilevel and multivariate models were used for the analysis of mortality and were performed in each stratum of severity level. RESULTS The study population included 142,859 patients admitted to 188 adult ICUs. There was an increase in the mean age of the patients and in the percentage of patients >79 years (11.2% vs. 12.7%, P<0.001). Also, the mean APACHE II score increased from 14.35±8.29 to 14.72±8.43 (P<0.001). The crude overall intra-UCI mortality remained unchanged (11.4%) but adjusted mortality rate in patients with APACHE II score between 11 and 25 decreased modestly in recent years (12.3% vs. 11.6%, odds ratio=0.931, 95% CI 0.883-0.982; P=0.008). CONCLUSION This study provides observational longitudinal data on case-mix of patients admitted to Spanish ICUs. A slight reduction in ICU mortality rate was observed among patients with intermediate severity level.

Abstract
Background The synthesis of cellulose is among the most important but poorly understood biochemical processes, especially in bacteria, due to its complexity and high degree of regulation. In this study, we analyzed both the production of cellulose by all known members of the Rhizobiaceae and the diversity of Rhizobium celABC operon predicted to be involved in cellulose biosynthesis. We also investigated the involvement in cellulose production and biofilm formation of celC gene encoding an endoglucanase (CelC2) that is required for canonical symbiotic root hair infection by Rhizobium leguminosarum bv. trifolii. Results ANU843 celC mutants lacking (ANU843ΔC2) or overproducing cellulase (ANU843C2+) produced greatly increased or reduced amounts of external cellulose micro fibrils, respectively. Calcofluor-stained cellulose micro fibrils were considerably longer when formed by ANU843ΔC2 bacteria rather than by the wild-type strain, in correlation with a significant increase in their flocculation in batch culture. In contrast, neither calcofluor-stained extracellular micro fibrils nor flocculation was detectable in ANU843C2+ cells. To clarify the role of cellulose synthesis in Rhizobium cell aggregation and attachment, we analyzed the ability of these mutants to produce biofilms on different surfaces. Alteration of wild-type CelC2 levels resulted in a reduced ability of bacteria to form biofilms both in abiotic surfaces and in planta. Conclusions Our results support a key role of the CelC2 cellulase in cellulose biosynthesis by modulating the length of the cellulose fibrils that mediate firm adhesion among Rhizobium bacteria leading to biofilm formation. Rhizobium cellulose is an essential component of the biofilm polysaccharidic matrix architecture and either an excess or a defect of this “building material” seem to collapse the biofilm structure. These results position cellulose hydrolytic enzymes as excellent anti-biofilm candidates.

Abstract
OBJECTIVE To describe the use and effectiveness of linezolid as an alternative treatment for methicillin-resistant Staphylococcus aureus. METHOD Demographic, clinical and safety data were collected from hospitalised patients. The information sources were the clinical records and the pharmacy programme. RESULTS Thirty patients were treated with linezolid (median age 69.3, 63% male). The median duration of treatment was 8 days. The most prevalent indication was soft tissues and skin infections (46.7%). The indications were off-label in 40% of cases. Linezolid was used as a targeted therapy in 53%, especially for coagulase-negative Staphylococcus. Clinical healing occurred in 83.3%, and microbiological healing in 40%. Three patients (10%) experienced side effects from using linezolid. CONCLUSION The effectiveness and safety of linezolid is similar to that described in the trials. Its off-label use and the high number of empirical treatments mean that new strategies must be developed.

Abstract
Diversity of 50 bacterial isolates recovered from root nodules of Prosopis farcta grown in different arid soils in Tunisia, was investigated. Characterization of isolates was assessed using a polyphasic approach including phenotypic characteristics, 16S rRNA gene PCR--RFLP and sequencing, nodA gene sequencing and MLSA. It was found that most of isolates are tolerant to high temperature (40°C) and salinity (3%). Genetic characterization emphasizes that isolates were assigned to the genus Ensifer (80%), Mesorhizobium (4%) and non-nodulating endophytic bacteria (16%). Forty isolates belonging to the genus Ensifer were affiliated to Ensifer meliloti, Ensifer xinjiangense/Ensifer fredii and Ensifer numidicus species. Two isolates belonged to the genus Mesorhizobium. Eight isolates failing to renodulate their host plant were endophytic bacteria and belonged to Bacillus, Paenibacillus and Acinetobacter genera. Symbiotic properties of nodulating isolates showed a diversity in their capacity to infect their host plant and fix atmospheric nitrogen. Isolate PG29 identified as Ensifer meliloti was the most effective one. Ability of Prosopis farcta to establish symbiosis with rhizobial species confers an important advantage for this species to be used in reforestation programs. This study offered the first systematic information about the diversity of microsymbionts nodulating Prosopis farcta in the arid regions of Tunisia.

Abstract
Avaliou-se o efeito de diferentes dietas sobre as características da carcaça e da carne de bovinos de corte em confinamento: dieta composta por silagem de milho e formulação fixa durante o período de confinamento (SMF); dieta composta por silagem de milho e formulação variável durante o período de confinamento (SMV); dieta composta por silagem de cana-de-açúcar e formulação fixa (SCF); dieta composta por silagem de cana-de-açúcar e formulação variável (SCV); SCV na metade inicial do confinamento e SMV no período final (SCV/SMV). O delineamento experimental foi inteiramente ao acaso, com cinco tratamentos e três repetições. Houve maior deposição de gordura renal-pélvica-inguinal (P=0,03), de gordura subcutânea (P=0,06) e de gordura na carcaça (P=0,06) nas dietas com silagem de milho (6,7kg; 6,2mm e 34,6%) em relação àquelas com silagem de cana-de-açúcar (5,3kg; 4,8mm e 31,7%). Houve maior (P=0,05) rendimento de contrafilé e de miolo de alcatra nas dietas com silagem de milho (10% e 6,9%) em relação às com silagem de cana-de-açúcar (9% e 6,6%). Não houve efeito das dietas sobre rendimento de cortes primários (P>0,1), perdas por cocção (P>0,3) e força de cisalhamento (P>0,1). O ajuste da formulação da dieta e a troca de silagem não influenciaram as características de carcaça e da carne. A utilização de silagem de cana-de-açúcar permitiu carcaças com acabamento satisfatório

Abstract
In the Peruvian Health System, Clinical Engineering does not exist as a topic of intervention. 59% of biomedical equipment is officially classified as operational, however next to apply the correct classification methodology and include security issues, only 10% of the equipment are suitable for use in patients. The serious consequences for patients, is opposite to the increased public investment in the health sector. Reversing this context leads to structural changes at all levels of the organization and they will be achievable only through an appropriate educational program. A strategy focused on joint of capacities called Health Technopole has managed to implement an innovative Model of Education in Healthcare Technology Management HTM and Clinical Engineering CE aimed at solving this problem. The proposal focused on strategies to strengthen the educational goals such as creating HTM & CE Units in hospitals, the implementation of the methodology: Problem Based Learning and Project Management in HTM & CE in classroom and on line courses. The process includes an effective interaction with global organizations through teleconferences, Internships, Workshops and Seminars. A key component was the sustained multidisciplinary approach. Health Technopole CENGETS is an expert adviser for the Ministry of Health and is called for trainings, design training programs for regional governments and also supports global organizations such as PAHO / WHO and ORAS / CONHU. The proposal of innovation applied to HTM & CE Education is effective and is a benchmark for similar countries.

Abstract
AIMS To identify several strains of Mesorhizobium amorphae and Mesorhizobium tianshanense nodulating Cicer arietinum in Spain and Portugal, and to study the symbiotic genes carried by these strains. METHODS AND RESULTS The sequences of 16S-23S intergenic spacer (ITS), 16S rRNA gene and symbiotic genes nodC and nifH were analysed. According to their 16S rRNA gene and ITS sequences, the strains from this study were identified as M. amorphae and M. tianshanense. The type strains of these species were isolated in China from Glycyrrhiza pallidiflora and Amorpha fruticosa nodules, respectively, and are not capable of nodulating chickpea. These strains carry symbiotic genes, phylogenetically divergent from those of the chickpea isolates, whose nodC and nifH genes showed more than 99% similarity with respect to those from Mesorhizobium ciceri and Mesorhizobium mediterraneum, the two common chickpea nodulating species in Spain and Portugal. CONCLUSIONS The results from this study showed that different symbiotic genes have been acquired by strains from the same species during their coevolution with different legumes in distinct geographical locations. SIGNIFICANCE AND IMPACT OF THE STUDY A new infrasubspecific division named biovar ciceri is proposed within M. amorphae and M. tianshanense to include the strains able to effectively nodulate Cicer arietinum.

Abstract
AIMS Despite the interest of phyllosphere microbiology, no studies have addressed the bacteria present in bract phyllosphere, an ecosystem that has special characteristics in palm trees because the dry bracts remain on the plant until pruning and may contain polymer-degrading bacteria involved in plant degradation. Therefore, the aim of this work was to characterize xylanolytic bacteria isolated from palm bract phyllosphere. METHODS AND RESULTS Twelve xylanolytic strains were isolated and characterized by phenotypic features and complete sequencing of 16S rRNA gene. The results showed that the isolates were phenotypically and genotypically diverse. Gram-positive isolates were classified into genus Paenibacillus some of them belonging to hitherto undescribed species of this genus. Gram-negative isolates were classified into genera Pseudomonas and Acinetobacter. CONCLUSIONS The results of this work confirm the complexity of the bacterial populations present in phyllospheric ecosystems and suggest that bacteria involved in plant degradation are present at the early degradation steps of this process in dry palm tree bracts. SIGNIFICANCE AND IMPACT OF THE STUDY This is the first study on bract phyllospheric bacteria able to hydrolyse vegetal polymers and offers a new perspective in the search of unexplored sources of xylanase-producing strains.

Abstract
Polymerase chain reation (PCR) fingerprints are used to characterize and recognize bacteria and are generally obtained using universal primers that generate an array of DNA amplicons, which can be separated by electrophoresis. Universal primers 8F and 1491 R have been used to amplify specifically 16S rDNA. We have used these primers at an annealing temperature of 50 degrees C. Agarose gel electrophoresis of PCR products revealed several bands. The band pattern of each bacterial species was different and the strains belonging to the same species shared an identical pattern. The patterns obtained did not show variations with plasmid DNA content or the growth stage of the bacteria. The peculiarity of the randomly amplified polymorphic DNA (RAPD) described in this work lies in the use of two large primers (proximately 20 nt) to obtain the pattern, since normally a only smaller primer is used, and in the new application for the primers used to amplify 16S rDNA. This new procedure, called two primers (TP)-RAPD fingerprinting, is thus rapid, sensitive, reliable, highly reproducible and suitable for experiments with a large number of microorganisms, and can be applied to bacterial taxonomy, ecological studies and for the detection of new bacterial species.

Abstract
In this work, we describe a rapid and simple method for total RNA extraction from bacteria and yeast. The method allows for the acquirement of high RNA yields while avoiding the use of phenol or other toxic reagents and is less expensive than other methods previously described. The extracted RNA is suitable for applications such as RT-PCR, Northern blot hybridization and low molecular weight RNA (LMW RNA) electrophoresis.

Abstract
Detection of intracellular myeloperoxidase (MPO), CD79a and CD3 has become the most specific tool for the assignment of myeloid, B- and T-lymphoid lineages in acute leukemias. In order to establish the best combination of monoclonal antibody reagent and sample preparation technique for the intracellular detection of these three markers, we compared six different cell fixation-permeabilization kits (Cytofix/Cytoperm, Fix and Perm, Intraprep, Intrastain, Permeacyte and Permeafix) using 12 fluorochrome conjugates derived from seven monoclonal antibody (mAb) clones. A total of 21 samples corresponding to normal peripheral blood (n=4), normal bone marrow (n=3), acute myeloblastic leukemia (AML, n=6), precursor B-acute lymphoblastic leukemia (ALL, n=6) and T-ALL (n=2) cases, were analysed in two centers. All fixation/permeabilization methods resulted in decreased side scatter and mostly increased forward scatter as compared to erythrocyte-lyse-washed and 1% paraformaldehyde fixed samples. The autofluorescence levels of the leukocyte populations was only significantly increased with use of the Cytofix/Cytoperm kit and mildly with the other techniques. In addition, non-specific staining increased significantly for combinations of any anti-MPO mAb with the Cytofix/Cytoperm kit and for the CD3 clone S4.1 combined with any intracellular method. Anti-MPO antibodies gave a stronger fluorescence signal when conjugated to PE than when coupled to FITC. In conclusion, MPO-7-PE, UCHT-1-PE (CD3) and any HM57-PE conjugate (CD79a) in combination with Fix and Perm, Intraprep, Intrastain or Permeafix, provided specific staining of the respective markers in sufficient intensities. Thus, combined selection of fixation/permeabilization kits and monoclonal antibody reagents against CD3, CD79a and MPO is required for obtaining optimal cytoplasmic detection of these antigens.

Abstract
For decades, time-lapse microscopy has been used to track dynamic events associated with biological phenomena. Time-lapse studies of the developing nervous system have been restricted to analysis of dissociated cell cultures or of a series of static images from living organisms. The advent of new fluorescent dyes and video imaging technology has produced novel views of the behavior of neurons in the context of the developing nervous tissue, such as migrations within and away from proliferative zones and navigation of axonal processes to synaptic targets. After fixation of the tissue preparation, time-lapse monitoring can be followed by other analytical techniques and forms of microscopy, e.g., immunocytochemistry or electron microscopy, producing information on the interactions of individual cells whose behavioral histories are known. The power of video time-lapse microscopy of living brain tissue lies in the firsthand documentation of developmental patterning, which in turn can serve as an experimental assay.

Abstract
We compare the effects of two of the main angiotensin convertase enzyme inhibitors, captopril and enalapril, aiming to evaluate their effects in the arterial circulation performance, micro-circulation, and changes in regional blood flow, assuming their property of lowering the angiotensin II blood levels, a very strong peripheral vasoconstrictor. We studied 22 patients: all of them with hypertension and/or skin ulcerations, dropping out those who had venous. They were evaluated periodically, clinically and with photoelectric plethysmography of lower extremities. To interpret the traces we designed an ideogram which gathered the plethysmographic behavior before and after the treatment. Nearly 80% showed considerable improvement in pain, functional capacity and plethysmographic traces patterns. healing of the ulcerations was achieved in all case. We propose some hypothesis to explain the good effect that we have observed.

Abstract
A case of scleromyxedema with associated rhabdomyolysis is reported. This appears to be a well-documented, although rare complication of scleromyxedema. This case is unique in that mucin was demonstrated in the muscle as well as the skin, and spontaneous resolution of the rhabdomyolysis occurred with the implementation of IV fluids and bed rest.
