Nowadays, fribromialgya is one of the nervous diseases with the highest comorbidity and chronic index. The peculiarity of this symptomatology is becausephysiological pain goes to different parts of the body. The symptomatology of fribromialgya and hysteria could have relation between them and even, sharing many similar simptoms. Therefore, we will focus on studyng two cases to resolve these questions and we will be able to see if fibromialgya has histerical symptoms.

Objectives: To examine the safety and effectiveness of cobalt-chromium everolimus eluting stents compared with bare metal stents. Design: Individual patient data meta-analysis of randomised controlled trials. Cox proportional regression models stratified by trial, containing random effects, were used to assess the impact of stent type on outcomes. Hazard ratios with 95% confidence interval for outcomes were reported. Data sources and study selection: Medline, Embase, the Cochrane Central Register of Controlled Trials. Randomised controlled trials that compared cobalt-chromium everolimus eluting stents with bare metal stents were selected. The principal investigators whose trials met the inclusion criteria provided data for individual patients. Primary outcomes: The primary outcome was cardiac mortality. Secondary endpoints were myocardial infarction, definite stent thrombosis, definite or probable stent thrombosis, target vessel revascularisation, and all cause death. Results: The search yielded five randomised controlled trials, comprising 4896 participants. Compared with patients receiving bare metal stents, participants receiving cobalt-chromium everolimus eluting stents had a significant reduction of cardiac mortality (hazard ratio 0.67, 95% confidence interval 0.49 to 0.91; P=0.01), myocardial infarction (0.71, 0.55 to 0.92; P=0.01), definite stent thrombosis (0.41, 0.22 to 0.76; P=0.005), definite or probable stent thrombosis (0.48, 0.31 to 0.73; P<0.001), and target vessel revascularisation (0.29, 0.20 to 0.41; P<0.001) at a median follow-up of 720 days. There was no significant difference in all cause death between groups (0.83, 0.65 to 1.06; P=0.14). Findings remained unchanged at multivariable regression after adjustment for the acuity of clinical syndrome (for instance, acute coronary syndrome v stable coronary artery disease), diabetes mellitus, female sex, use of glycoprotein IIb/IIIa inhibitors, and up to one year v longer duration treatment with dual antiplatelets. Conclusions: This meta-analysis offers evidence that compared with bare metal stents the use of cobalt-chromium everolimus eluting stents improves global cardiovascular outcomes including cardiac survival, myocardial infarction, and overall stent thrombosis.

Peutz¿Jeghers syndrome (PJS, MIM175200) is an autosomal dominant condition defined by the development of characteristic polyps throughout the gastrointestinal tract and mucocutaneous pigmentation. The majority of patients that meet the clinical diagnostic criteria have a causative mutation in the STK11 gene, which is located at 19p13.3. The cancer risks in this condition are substantial, particularly for breast and gastrointestinal cancer, although ascertainment and publication bias may have led to overestimates in some publications. Current surveillance protocols are controversial and not evidence-based, due to the relative rarity of the condition. Initially, endoscopies are more likely to be done to detect polyps that may be a risk for future intussusception or obstruction rather than cancers, but surveillance for the various cancers for which these patients are susceptible is an important part of their later management. This review assesses the current literature on the clinical features and management of the condition, genotype¿phenotype studies, and suggested guidelines for surveillance and management of individuals with PJS. The proposed guidelines contained in this article have been produced as a consensus statement on behalf of a group of European experts who met in Mallorca in 2007 and who have produced guidelines on the clinical management of Lynch syndrome and familial adenomatous polyposis.

Quan hom demana finançament per desenvolupar un projecte científic, un dels requisits acostuma a ser informar sobre el seu caràcter científic, bàsic o aplicat, una dicotomia que, si se'm permet dir-ho, amaga una certa perversió. La ciència aplicada és aquella que adapta coneixements científics a necessitats concretes de les persones, com per exemple necessitats tècniques o biomèdiques. La ciència bàsica, en canvi, estudia aspectes concrets del funcionament de la natura, sense que vagin específicament dirigits a resoldre necessitats concretes [...].

Els humans sentim un profund respecte per la mort des de temps immemorials, però massa sovint aquest respecte és més intens que el que sentim per la pròpia vida. Altrament, costa d'entendre que les recents imatges de soldats alemanys jugant amb cranis d'una fossa comuna a l'Afganistan hagin causat tant rebombori o més que les innombrables víctimes civils que diàriament es produeixen en aquest i en altres conflictes, els cranis de les quals podrien haver-se estalviat d'anar a parar tan precipitadament i abans d'hora a una fossa. De fet, em temo que no és respecte per la mort en si mateixa el que sentim, sinó por a la pròpia mort, al patiment personal i a l'angoixa que sentim per la pèrdua d'un ésser estimat, que reflectim i intentem superar d'aquesta manera en unes despulles inertes, tant profanant-les com sacralitzant-les [...]

El fracaso renal agudo afecta entre un 1 y un 25% de los pacientes ingresados en unidades de cuidados intensivos, cifras que varían según la población y los criterios estudiados. Las complicaciones derivadas del fracaso renal agudo (hipervolemia, acidosis metabólica, hiperpotasemia, hemorragias) se tratan pero la mortalidad sigue siendo elevada a pesar de los avances tecnológicos de los últimos años ya que, habitualmente, el fracaso renal agudo está asociado a sepsis, insuficiencia respiratoria, heridas graves, complicaciones quirúrgicas o coagulopatías de consumo. El rango de mortalidad va desde un 30 a un 90%. Aunque no disponemos de una definición universalmente aceptada, la clasificación RIFLE aporta una herramienta operativa tanto para definir el grado de fracaso renal agudo como para homogeneizar el inicio de las técnicas de depuración extrarrenal y evaluar los resultados obtenidos. En consecuencia, las enfermeras que trabajan en una unidad de cuidados intensivos deben estar familiarizadas con esta afección, con su tratamiento (farmacológico o sustitutivo) y con la prevención de las posibles complicaciones. De igual manera han de ser capaces de detectar las manifestaciones de dependencia de cada una de las necesidades básicas e identificar los problemas de colaboración para conseguir un plan de cuidados individualizado.

Descrito en 1856 por Wunderlich, el hematoma perirrenal espontáneo es una patología infrecuente, en la que a pesar de llegar al diagnóstico de una manera relativamente sencilla con estudios imagen, el poder determinar la etiología representa un reto y es motivo de múltiples estudios y procedimientos invasivos, algunas veces sin poder llegar a esclarecer la causa1. Los hematomas renales y esplénicos están asociados con frecuencia a traumatismos abdominales y más raramente se deben a alteraciones de la coagulación e infecciones. Otras causas menos frecuentes son procesos inflamatorios, diátesis sanguínea,...

A variety of language disturbances including aphasia have been described after subcortical stroke but less is known about the factors that influence the long-term recovery of stroke-induced language dysfunction. We prospectively examined the role of the affected hemisphere and the lesion site in the occurrence and recovery of language deficits in nonthalamic subcortical stroke. Forty patients with unilateral basal gangliastroke underwent language assessment within 1 week, 3 months and 1 year after stroke. Disturbances in at least one language domain were observed in 35 patients during the first week post stroke including aphasia diagnosed in 11 patients. Importantly, the appearance of deficits after stroke onset and the improvement of language function were not determined by the site of subcortical lesion, but instead were critically influenced by the affected hemisphere. In fact, the language impairments following left and right basal ganglia stroke mirrored the language dysfunction observed after cortical lesions in the same hemisphere. A significant overall language improvement was observed at 3 months after stroke, although residual deficits in languageexecutive function were the most commonly observed impairment at 1 year follow-up. Although a substantial improvement of language function can be expected after nonthalamic subcortical stroke, our findings suggest that language recovery may not be fully achieved at 1 year post

Non-typable Haemophilus influenzae (NTHi) is a Gram negative pathogen that causes acute respiratory infections and is associated with the progression of chronic respiratory diseases. Previous studies have established the existence of a remarkable genetic variability among NTHi strains. In this study we show that, in spite of a high level of genetic heterogeneity, NTHi clinical isolates display a prevalent molecular feature, which could confer fitness during infectious processes. A total of 111 non-isogenic NTHi strains from an identical number of patients, isolated in two distinct geographical locations in the same period of time, were used to analyse nine genes encoding bacterial surface molecules, and revealed the existence of one highly prevalent molecular pattern (lgtF+, lic2A+, lic1D+, lic3A+, lic3B+, siaA−, lic2C+, ompP5+, oapA+) displayed by 94.6% of isolates. Such a genetic profile was associated with a higher bacterial resistance to serum mediated killing and enhanced adherence to human respiratory epithelial cells.

Systemic lupus erythematosus (SLE) predominantly affects young women in their 20s. In 40 out of 250 (16%) patients with SLE seen in our hospital disease onset occurred after the age of 50. The interval between the time of onset and diagnosis was five years in this older group compared with three years in the younger group. Arthritis, as a first symptom, was less common in the older onset group. During the follow up a lower incidence of arthritis, malar rash, photosensitivity, and nephropathy was found in the older onset group. In contrast, this group showed an increased incidence of myositis. High titres of anti-dsDNA tended to occur less often and the incidence of anti-Ro antibodies was lower in the older onset group. These features seem to distinguish patients with older onset SLE as a particular subset.

A prospective two dimensional and Doppler echocardiographic study of 70 consecutive patients with systemic lupus erythematosus (SLE) and 40 controls was carried out. Forty patients (57%) were found to have echocardiographic disturbance. Valvular abnormalities were detected in 31 patients (44%) and in only two controls (5%). Mitral valve abnormalities were the most common findings (23/70 (33%)) with mild or moderate regurgitation the most frequent lesion (16% and 9% respectively). Three patients (4%) had a morphological echocardiographic pattern suggestive of non-infective verrucous vegetations affecting the mitral valve. No patient had haemodynamically significant clinical valve disease. Pericardial effusion was identified in 19 patients (27%), of whom 14 had mild and clinically silent disease. Myocardial abnormalities were found in 14 patients (20%), but clinical features of myocardial dysfunction were present in only one. Patients with antiphospholipid antibodies were found to have an increased prevalence of endocardial lesions, mainly valvular regurgitation. It is concluded that the inclusion of echocardiography in a study protocol of patients with SLE can identify an important subset of patients with cardiac abnormalities, many of which are clinically silent. In addition, the association of antiphospholipid antibodies with endocardial lesions suggests that these antibodies may have a prominent role in the pathogenetic mechanisms of heart valve disease in SLE.
