A robust PCR for the differentiation of potential virulent strains of Haemophilus parasuis.

BACKGROUND: Haemophilus parasuis is the etiological agent of Glässer's disease in swine. H. parasuis comprises strains with heterogeneous virulence capacity, from non-virulent to highly virulent. Determination of the pathogenic potential of the strains is important for diagnosis and disease control. The virulence-associated trimeric autotransporters (vtaA) genes have been used to predict H. parasuis virulence by PCR amplification of their translocator domains. Here, we report a new and improved PCR designed to detect a different domain of the vtaA genes, the leader sequence (LS) as a diagnostic tool to predict virulence. METHODS: A collection of 360 H. parasuis strains was tested by PCR with LS specific primers. Results of the PCR were compared with the clinical origin of the strains and, for a subset of strains, with their phagocytosis and serum resistance using a Chi-square test. RESULTS: LS-PCR was specific to H. parasuis, and allowed the differential detection of the leader sequences found in clinical and non-clinical isolates. Significant correlation was observed between the results of the LS-PCR and the clinical origin (organ of isolation) of the strains, as well as with their phagocytosis and serum susceptibility, indicating that this PCR is a good predictor of the virulence of the strains. In addition, this new PCR showed a full correlation with the previously validated PCR based on the translocator domain. LS-PCR could be performed in a wide range of annealing temperatures without losing specificity. CONCLUSION: This newly described PCR based on the leader sequence of the vtaA genes, LS-PCR, is a robust test for the prediction of the virulence potential of H. parasuis strains.

[Femoral hypoplasia-unusual facies syndrome: A case report]. / Síndrome de hipoplasia femoral y facies inusual: reporte de un caso.

INTRODUCTION: Femoral hypoplasia-unusual facies syndrome is a rare disease with variable expressivity, although cases have been reported with an autosomal dominant pattern. It particularly affects the structures of the face associated with hypoplasia of the femur. Its aetiology is relatively unknown. However, this syndrome has been associated with maternal diabetes, drug exposure, viral infections, radiation, and oligohydramnios. OBJECTIVE: The case of a newborn with this syndrome is presented. CLINICAL CASE: Newborn of 41 weeks gestation with small nose, thin upper lip, micrognathia, long philtrum, low set ears, epicanthal folds, dysplastic hips showing flexion, and adduction of the right leg, and shortening at the expense of the thigh. X-ray images revealed femoral hypoplasia and dysplastic acetabular roof. Different physicians from other specialties who excluded other associated malformations performed a complete evaluation. Surgical bone lengthening of lower limb is scheduled at 5 months of age, with the purpose that she walks with her own feet; at the same time she began management with kinesiotherapy. CONCLUSIONS: Femoral hypoplasia-unusual facies syndrome is a rare condition. A multidisciplinary health care team must treat individuals with femoral hypoplasia-unusual facies syndrome.

Risk factors for complications in total hip arthroplasty. / Factores de riesgo para complicaciones en artroplastia total de cadera.

INTRODUCTION AND OBJECTIVE: Hip arthroplasty represents a significant advancement in the treatment of refractory chronic joint pain, improving quality of life and functionality. The objective of this study is to identify the risk factors associated with local and systemic complications in patients treated with total hip arthroplasty. METHODS: Observational, analytical, retrospective cohort study, which included 304 participants treated with total hip replacement. Comparison of variables between two groups was performed; 38 participants in the group with complications and 266 participants in the group without complications. RESULTS: The mean age in the complication group was 66 years (SD 18.7) and in the uncomplicated group it was 67,1 years (SD 15.1) (p 0,686). Female sex was observed in 73.3% of the group with complications and 65% in the group without complications. (p 0.292). Risk factors were: hip fracture as an indication for arthroplasty RR 1.33 [95% CI 1.004;1.775 p 0.047], coronary heart disease RR 1.31 [95% CI 1.067;1.616 p 0.010] and surgical bleeding equal to or greater than 400 cc RR 1.11 [95% CI 1.012;1.218 p 0.028]. CONCLUSIONS: The risk factors for complications in total hip arthroplasty were: hip fracture as the indication for arthroplasty, coronary artery disease, and surgical bleeding equal to or greater than 400 cc.

[Colorectal polyps: update on diagnosis]. / Pólipos colorectales: actualización en el diagnóstico.

Histological diagnosis determines the clinical behavior of colorectal polyps. Recently new types of polyps have been described and the classification has become wider and more complex. Our aim is update the current concepts in the knowledge of colorectal polyps.

[Increase of intraepithelial lymphocytes in patients with irritable bowel syndrome]. / Incremento de Linfocitos Intraepiteliales en Pacientes con Sindrome de Intestino Irritable.

Several studies have shown increased numbers of intraepithelial lymphocytes (IEL), mast cells, enterochromaffin cells in colonic mucosa of patients with Irritable Bowel Syndrome (IBS). Many of these findings are based is based on immunohistochemistry results, which is not available in general hospitals. Our objective is to study the histological findings observed in colon biopsies from patients with IBS compared with a group without IBS, using only histochemistry. Twenty five (25) patients were included: 16 with IBS and 9 without IBS. We found increased numbers of IEL in patients with IBS (p=0,002). A group of patients with IBS (41.9%) who fulfilled histological criteria for lymphocytic colitis were excluded. There was no significant difference in mast cells, enterochromaffin cells or eosinophils.

Moraxella porci sp. nov., isolated from pigs.

Nine Gram-negative, catalase- and oxidase-positive, coccus-shaped bacteria were isolated from pigs affected by different pathological processes. Phenotypic and genotypic methods were adopted to determine the relationships of these new isolates to recognized species of the genus Moraxella. Analysis of the 16S rRNA gene sequences demonstrated that the clinical isolates represented a new lineage within the genus Moraxella. The isolates were closely related to Moraxella cuniculi and Moraxella pluranimalium with 16S rRNA gene sequence similarities of 98.1 % and 99.1 %, respectively. The isolates displayed DNA-DNA relative binding ratios of 74 % to each other, but distinctly lower levels of DNA-DNA hybridization were observed with phylogenetically closely related moraxellae (<32 %). The new isolates could be distinguished from all other recognized species of the genus Moraxella by physiological and biochemical tests. On the basis of the phenotypic and molecular data, the nine new isolates from pigs represent a novel species within the genus Moraxella, for which the name Moraxella porci sp. nov. is proposed. The type strain is SN9-4M(T) (=CECT 7294(T)=CCUG 54912(T)).

Eliminating congenital rubella syndrome in Spain: does massive immigration have any influence?

In this short report we highlight the importance of implementing good immunization programs adapted to the epidemiological situation of rubella and congenital rubella syndrome (CRS), discuss the influence of massive immigration and stress the need to improve surveillance and control by implementing comprehensive national surveillance and promoting awareness among primary healthcare workers and midwives to find out any signs and symptoms compatible with rubella in pregnant women who have recently arrived from countries with high susceptibility to rubella infection.

Characterisation of Bergeyella spp. isolated from the nasal cavities of piglets.

The aim of this study was to characterise bacteria in the genus Bergeyella isolated from the nasal passages of healthy piglets. Nasal swabs from 3 to 4 week-old piglets from eight commercial domestic pig farms and one wild boar farm were cultured under aerobic conditions. Twenty-nine Bergeyella spp. isolates were identified by partial 16S rRNA gene sequencing and 11 genotypes were discriminated by enterobacterial repetitive intergenic consensus (ERIC)-PCR. Bergeyella zoohelcum and Bergeyella porcorum were identified within the 11 genotypes. Bergeyella spp. isolates exhibited resistance to serum complement and phagocytosis, poor capacity to form biofilms and were able to adhere to epithelial cells. Maneval staining was consistent with the presence of a capsule. Multiple drug resistance (resistance to three or more classes of antimicrobial agents) was present in 9/11 genotypes, including one genotype isolated from wild boar with no history of antimicrobial use. In conclusion, Bergeyella spp. isolates from the nasal cavities of piglets showed some in vitro features indicative of a potential for virulence. Further studies are necessary to identify the role of Bergeyella spp. in disease and within the nasal microbiota of pigs.

Dynamics of Haemophilus parasuis genotypes in a farm recovered from an outbreak of Glässer's disease.

Haemophilus parasuis is a colonizer of the upper respiratory tract of pigs, although it is better known as the etiological agent of Glässer's disease. Interestingly, several strains can be isolated from a single farm, as determined by both genotyping and serotyping. However, it is not known how an outbreak and the subsequent treatment affect the population of H. parasuis strains. In this study, a farm was studied during an outbreak of Glässer's disease and 1 year after antimicrobial treatment and elimination of clinical signs. Bacterial isolation was attempted from nasal swabs and lesions. After isolation, antimicrobial susceptibility, serotype and genotype were determined. Two different genotyping techniques, enterobacterial repetitive intergenic consensus (ERIC)-PCR and multilocus sequence typing (MLST) were used. The H. parasuis strain that was isolated from lesions during the disease outbreak clustered with other virulent strains by both MLST and serotyping analysis. Nasal isolates were included in the corresponding nasal cluster by MLST, but they presented high variability by serotyping. These nasal isolates included serotypes previously classified as virulent and non-virulent. Finally, we found that during the antimicrobial treatment the diversity of strains isolated in the farm was affected and just one strain, which was resistant to the treatment, was detected. One year after the treatment strain diversity was back to normal (three strains).

First isolation of Haemophilus parasuis and other NAD-dependent Pasteurellaceae of swine from European wild boars.

Haemophilus parasuis is a colonizer of the upper respiratory tract of pigs and the etiological agent of Glässer's disease, which is characterized by a fibrinous polyserositis, meningitis and arthritis. Glässer's disease has never been reported in wild boar (Sus scrofa), although antibodies against H. parasuis have been detected. The goal of this study was to confirm the presence of this bacterium in wild boar by bacterial isolation and to compare the strains to H. parasuis from domesticated pigs. Therefore, nasal swabs from 42 hunted wild boars were processed for bacterial isolation and subsequent H. parasuis identification by specific PCR, biochemical tests and 16S rRNA gene sequencing. Two different strains of H. parasuis from two wild boars were isolated. These strains belonged to serotype 2 and were included by 16S rRNA gene sequencing and MLST analysis in a cluster with other H. parasuis strains of nasal origin from domestic pigs. During this study, Actinobacillus minor and Actinobacillus indolicus, which are NAD-dependent Pasteurellaceae closely related to H. parasuis, were also isolated. Our results indicate similarities in the respiratory microbiota of wild boars and domestic pigs, and although H. parasuis was isolated from wild boars, more studies are needed to determine if this could be a source of H. parasuis infection for domestic pigs.

[Determining factors in the sedation of geriatric and oncology patients treated at home]. / Factores condicionantes de sedación en pacientes geriátricos y oncológicos atendidos en el domicilio.

INTRODUCTION: Sedation, used as a therapeutic measure in the field of Palliative Care, continues to present difficulties for many professionals in its management and indications. Is varied existing literature in this regard, often exclusive cancer patients. Our objective is to analyse the characteristics of patients attended by a Home Care Support Team who required sedation compared to non-sedated patients, for possible determining factors for its use that could help in decision-making. METHOD: A prospective analytical study conducted in Barbastro (Huesca) from September 2007 to February 2011. The study population are patients referred to the Home Care Support Team of Barbastro. MAIN VARIABLES: Age, sex, medical history, symptoms, previous and current Barthel, Karnofsky, primary caregiver, previous drugs, drugs after intervention, sedation yes/no. RESULTS: Required sedation 16.6% (n=106) of the cases (N=638). Sedated patients were younger, with no differences in sex, and the large majority (83%) were oncology patients. The presence of metastases showed no differences in need for sedation. Sedated patients have an increased functional impairment, determined by Barthel index decreased and a worse Karnofsky. Sedated patients showed increased frequency of uncontrolled symptoms, except psychomotor agitation, a fact determined by the medications used pre- and post-intervention. CONCLUSIONS: The presence of neoplastic disease, marked with existence of functional decline, and uncontrolled clinical need for certain medications to control symptoms may determine the need for sedation at the end of the process, above other factors such as patient comorbidity.

The TITAN-AMI multicenter registry evaluating the usage of Titan2 stent in patients with ST segment elevation myocardial infarction. Final result at 12-month follow-up.

AIM: Primary percutaneous coronary intervention with stent implantation is the recommended treatment for patients with ST elevation myocardial infarction (STEMI). Data from randomised trials showed good performance by a titanium-nitric-oxide coated stent in this context. The aim of this study was to confirm these data. METHODS: A multicentre registry was compiled in 23 hospitals in Spain in an all-comers population. We selected patients with STEMI from a global Titan AMI registry that included patients with acute coronary syndrome. Primary endpoint was the composite of cardiac death, non-fatal myocardial infarction, stent thrombosis and target lesion revascularisation, at 12-month follow-up. RESULTS: The study included 893 patients with STEMI. We included all possibilities for PCI: 86.6% primary, 5% facilitated after successful fibrinolysis and 8.4% rescue PCI after failed fibrinolysis. The primary endpoint was reached in 8.4% of the patients: cardiac death 2.7%, reinfarction 3.4%, target lesion revascularisation 3.5% and definite or probable stent thrombosis 2.8%. The majority of stent thromboses presented in the first 30 days after PCI. CONCLUSION: A bioactive stent (titanium-nitric-oxide coated stent) is a possible alternative for the treatment of patients with STEMI. One-year follow-up showed better results than those presented by a regular bare-metal stent or first-generation drug-eluting stent in terms of stent thrombosis.

[Advanced urethral carcinoma. Which is the best management of a infrequent disease?]. / Carcinoma uretral con extensión locorregional importante. Cómo manejamos una patología infrecuente?

Urethral cancer is an uncommon tumor (<0.1% of all genitourinary neoplasms). Most of them are squamous carcinoma, adenocarcinomas are about 5% of all urethral cancer. Surgery is the only curative treatment. Surgical technics depend of tumoral location and extension. Conservative surgery is elective if survival is not compromised. Extensive surgery is needed in large lesions. Chemotherapy (CT) and radiotherapy (RT) must be used in patients in which surgery is not possible. Due to the low incidence of this neoplasm is not well established the best therapeutic approach. We present the case of a female (35 years old) with a diagnosis of urethral adenocarcinoma. The initial stage was IV due to non-regional lymph nodes metastases. Surgery was impossible and the patient received chemotherapy and radiotherapy. The patient achieved complete response with CT but a progression was observed in course of RT. The patient died due to systemic progression.

[Pancreatic abscess. Extraperitoneal drainage]. / Absceso pancreático, drenaje por vía extraperitoneal.

The pancreatic abscess occurs in two to six per cent of patients with acute pancreatitis and in 40 to 50 per cent of whom develop the severe form of the disease. The postoperative morbidity rate is 85 to 90 per cent and the mortality rate is 30 to 50 per cent due to persistence or recurrence of infection. The anatomical location and dissemination of the pancreatic abscess allows an extraperitoneal approach. Twelve patients with pancreatic abscess are reported. Seven males and five females, with an average age of 36 years. Fever, abdominal pain, cutaneous hypersensitivity and palpable abdominal mass were the most frequent clinical signs. Most of them developed multiple organic failure, leukocytosis, hyperglycemia, increasing L.D.H. and alkaline phosphatase levels. The CAT scan was most useful to localize the abscess. About 83 per cent of patients had been operated on previously. The extraperitoneal surgical approach was anterior in 10 patients and posterior in two patients. Ten patients developed complications that resolved with conservative measures. Two patients (17%) died. Extraperitoneal drainage is a valid alternative to prevent peritoneal contamination and some other serious postoperative complications in the management of pancreatic abscess.

Factores condicionantes de sedación en pacientes geriátricos y oncológicos atendidos en el domicilio / Determining factors in the sedation of geriatric and oncology patients treated at home

Introducción. La sedación, como medida terapéutica utilizada en el ámbito de los Cuidados Paliativos, sigue presentando para muchos profesionales dificultad en su manejo e indicaciones. Es muy variada la bibliografía existente en este sentido, muchas veces exclusiva de los pacientes oncológicos. Nuestro objetivo es analizar las características de los pacientes atendidos por un Equipo de Soporte para Atención Domiciliaria que precisaron sedación frente a los no sedados, para determinar posibles factores condicionantes de la misma que puedan ayudar en la toma de decisiones. Método. Estudio analítico prospectivo realizado en el sector sanitario de Barbastro (Huesca) desde septiembre del año 2007 hasta febrero del año 2011. La población a estudio fueron los pacientes derivados al Equipo de Soporte para Atención Domiciliaria de Barbastro. Variables principales. Edad, sexo, antecedentes médicos, síntomas, Barthel previo y actual, Karnofsky, cuidador principal, fármacos previos, fármacos tras intervención, sedación sí/no. Resultado. Requirieron sedación el 16,6% (n=106) de los casos (N=638). Los pacientes sedados fueron más jóvenes, sin diferencias por sexo. Un 83% fueron oncológicos. La presencia de metástasis no mostró diferencias respecto a la necesidad de sedación. Los pacientes sedados presentaron un mayor declive funcional, determinado mediante un descenso en el índice de Barthel y un peor Karnofsky. Los pacientes sedados mostraron una mayor frecuencia de síntomas no controlados, con excepción de agitación psicomotriz, hecho determinado por las medicaciones usadas pre y postintervención. Conclusiones. La presencia de enfermedad oncológica, con existencia de declive funcional marcado, clínica no controlada y necesidad de determinadas medicaciones para el control de la sintomatología pueden determinar la necesidad de sedación al final del proceso, por encima de otros factores como la comorbilidad del paciente (AU)

Papel del ESAD en el tratamiento del dolor. Análisis pre-post intervención en un entorno rural / HSCT role in the treatment of pain. Analysis pre-post intervention in a rural environment

Objetivos: Determinar la frecuencia de uso de analgésicos en pacientes terminales atendidos en domicilio, analizando factores que pudieran intervenir en la percepción del dolor, además de las actuaciones llevadas a cabo. Material y métodos: Estudio analítico prospectivo e intervencional con pacientes derivados al Equipo de Soporte para Atención Domiciliaria (ESAD) de Barbastro. Variables estudiadas: edad, sexo, número de visitas, tiempo de seguimiento, presencia de dolor y de otros síntomas concomitantes, Escala Visual Analógica (EVA), diagnóstico, analgésicos previos y post-intervención, dosis media previa de analgésicos y post-intervención. Estudio estadístico con SPSS 15.0. Resultados: n = 638, 53,9 % hombres (n = 344), edad media 79,64 ± 10,8 años, 56 % oncológicos (n = 357), seguimiento medio 56 ± 56,56 días, media de 2,68 ± 2,5 visitas por proceso. Dolor en primera visita 43,3 % (n = 276), EVA media 6,54 ± 1,87, dolor 47,1 % de hombres (n = 162) y 38,8 % de mujeres (n = 114) (p < 0,05), dolor en 56,6 % de oncológicos (n = 202) y en 26,3 % de crónico-dependientes (n = 74) (p < 0,001). No diferencias en EVA entre grupos. Entre analgésicos pautados en pacientes con dolor controlado y sin controlar previa intervención del ESAD encontramos diferencias estadísticamente significativas (p < 0,005) en morfina y tramadol, y con mayor significación (p < 0,001) en fentanilo transdérmico y transmucosa, paracetamol, metamizol y AINE, todos más frecuentes en dolor no controlado. Las dosis medias previas de todos estos fármacos no mostraron diferencias significativas entre los grupos, aunque eran mayores en el grupo de dolor no controlado. En estos, se pautan o modifican analgésicos, encontrándose diferencias estadísticamente significativas pre-post intervención (p < 0,001) en fentanilo transdérmico y transmucosa, tramadol, paracetamol, metamizol, AINE, pregabalina y con p < 0,05 en gabapentina. Se obtiene diferencias (p < 0,05) únicamente en las dosis posteriores a la actuación del ESAD en fentanilo transdérmico y codeína. Obtenemos correlaciones positivas entre dolor y anorexia, ansiedad, depresión e insomnio; en pacientes oncológicos entre dolor y ansiedad e insomnio, y en pacientes crónico-dependientes entre dolor, náuseas y depresión. No diferencias entre grupos en uso previo de benzodiacepinas, antidepresivos y otros tratamientos, aunque sí en clínica de depresión, ansiedad e insomnio. Tras intervención, diferencias significativas en uso de estos tratamientos y de sedación. Conclusiones: Tras la actuación del ESAD se puede apreciar el aumento progresivo de todas las medicaciones analgésicas; se debería realizar una valoración completa de la sintomatología del paciente y un tratamiento de síntomas multifactorial, además de interrogar al paciente de forma adecuada acerca de la presencia de síntomas asociados, dada la elevada correlación de los mismos (AU)

Objectives: To determine the frequency of use of analgesics in terminal patients attended in home, and factors that may be involved in pain perception, in addition to the interventions carried out. Methods: prospective, interventional and analytical study in patients attended to Homecare Support Team (HSCT) of Barbastro. Variables studied: age, sex, number of visits, time tracking, presence of pain and other concomitant symptoms, Visual Analogic Scale (VAS), diagnosis, analgesics previous and post-intervention, previous and post-intervention average dose of analgesics. Statistical study with SPSS 15.0. Results: n = 638, men 53.9 % (n = 344), mean age 10.8 ± 79.64 years, cancer patient 56 % (n = 357), mean follow-up time 56 ± 56.56 days, 2.5 ± 2.68 mean visits per process. Pain in first visit 43.3 % (n = 276), mean VAS 6.54 ± 1.87, pain 47.1 % of men (n = 162) and 38.8 % of women (n = 114) (p < 0.05), pain in oncology 56.6 % (n = 202) and 26.3 % of non-cancer patients (n = 74) (p < 0.001). No differences between groups in VAS. Before intervention by HCST we found statistically significant differences (p < 0.005) on morphine and tramadol, and greater significance (p < 0.001) in transdermal and transmucosal fentanyl, paracetamol, metamizol and NSAIDs, all more common in uncontrolled pain. Previous mean doses of all these drugs showed no significant differences between groups, although they were higher in the group of uncontrolled pain. In these, analgesics were prescribed or modified, being statistically significant difference pre-post-intervention (p < 0.001) in transdermal and transmucosal fentanyl, tramadol, paracetamol, metamizol, NSAIDs, pregabalin and with p < 0.05 in gabapentin. Was obtained difference (p < 0.05) in mean dose only in transdermal fentanyl and codeine dose post-intervention of HCST. We obtain positive correlations between pain and anorexia, anxiety, depression and insomnia; in cancer patients between pain and anxiety and insomnia, and non-cancer patients between pain, nausea and depression. No differences between groups in previous use of benzodiazepines, antidepressants and other treatments; there was differences in depression, anxiety and insomnia. After intervention, we obtain significant differences in use of these treatments and sedation. Conclusions: after intervention of HCST there was gradual increase of all analgesic; it should conduct a full assessment of the patient’s symptoms and treatment of multifactorial symptoms in addition to questioning the patient adequately about the presence of associated symptoms, given the high correlation of them (AU)

Sow vaccination modulates the colonization of piglets by Haemophilus parasuis.

Haemophilus parasuis is the etiologic agent of Glässer's disease in pigs and a colonizer of the upper respiratory tract of healthy pigs. A good balance between colonization and immunity is important to avoid a disease outbreak. This work studied the colonization of H. parasuis in healthy piglets coming from vaccinated and non-vaccinated sows. Piglets from vaccinated sows had higher IgG levels at early time points and subsequently were colonized later and to a lower degree than piglets from non-vaccinated ones. The variability of H. parasuis isolates was investigated by 2 genotyping methods: enterobacterial repetitive intergenic consensus (ERIC)-PCR and multilocus sequence typing (MLST). A high turnover of strains was found in both groups of piglets, with few strains found on more than one sampling occasion. We found a higher number of H. parasuis strains (16 strains) within a given farm than previously thought. Overall, more H. parasuis diversity was found in piglets from non-vaccinated sows than in those from vaccinated sows. These results indicate that vaccination of sows in a farm delays the colonization of piglets and reduces the carriage and heterogeneity of H. parasuis strains.
