La violencia contra la mujer en la pareja como factor asociado a una mala salud física y psíquica.

OBJECTIVE: To study the impact of intimate partner violence (IPV) on women's physical and psychological health. DESIGN: Cross-sectional study. SETTING:Primary care centers in 3 Andalusian provinces. PATIENTS: A total of 425 women, aged 18 to 65 years, were recruited following the same randomisation process in 6 primary care centers. MEASUREMENTS: A self-administered structured questionnaire for this study was used to gather the information. As well as sociodemographic variables, the instrument included questions about IPV, physical health indicators (chronic disease and type, lifetime surgeries, days in bed), psychological health (psychological morbidity, use of tranquilizers, antidepressants, pain killers, alcohol and recreational drugs), self-perceived health and social support. RESULTS: Of 425 women, 31.5% ever experienced any type of partner violence. Women experiencing IPV were more likely to suffer a chronic disease. IPV was significantly associated with a number of adverse health outcomes, including spending more than 7 days in bed in the last three months (ORa=2.96; CI 95%, 1.00-8.76), psychological morbidity (ORa=2.68; CI 95%, 1.60-4.49) and worse self-perceived health (ORa=1.89; CI 95%, 1.04-3.43), after controlling for potential confounding variables. CONCLUSION: This study shows that ever experiencing IPV is associated with a worse psychological and self-perceived health. Physical injuries are not the only "evidence" of the presence of IPV. Primary health care professionals are in a privileged position to help women who are abused by their partners.

Blockade of both alpha1A- and alpha1B-adrenergic receptor subtype signaling is required to inhibit neointimal formation in the mouse femoral artery.

Attenuation of early restenosis after percutaneous coronary intervention (PCI) is important for the successful treatment of coronary artery disease. Some clinical studies have shown that hypertension is a risk factor for early restenosis after PCI. These findings suggest that alpha(1)-adrenergic receptors (alpha(1)-ARs) may facilitate restenosis after PCI because of alpha(1)-AR's remarkable contribution to the onset of hypertension. In this study, we examined the neointimal formation after vascular injury in the femoral artery of alpha(1A)-knockout (alpha(1A)-KO), alpha(1B)-KO, alpha(1D)-KO, alpha(1A)-/alpha(1B)-AR double-KO (alpha(1AB)-KO), and wild-type mice to investigate the functional role of each alpha(1)-AR subtype in neointimal formation, which is known to promote restenosis. Neointimal formation 4 wk after wire injury was significantly (P < 0.05) smaller in alpha(1AB)-KO mice than in any other group of mice, while blood pressures were not altered in any of the groups of mice after wire injury compared with those before it. These results suggest that lack of both alpha(1A)- and alpha(1B)-ARs could be necessary to inhibit neointimal formation in the mouse femoral artery.

Lifetime alcohol use and overall and cause-specific mortality in the European Prospective Investigation into Cancer and nutrition (EPIC) study.

OBJECTIVES To investigate the role of factors that modulate the association between alcohol and mortality, and to provide estimates of absolute risk of death. DESIGN The European Prospective Investigation into Cancer and nutrition (EPIC). SETTING 23 centres in 10 countries. PARTICIPANTS 380 395 men and women, free of cancer, diabetes, heart attack or stroke at enrolment, followed up for 12.6 years on average. MAIN OUTCOME MEASURES 20 453 fatal events, of which 2053 alcohol-related cancers (ARC, including cancers of upper aerodigestive tract, liver, colorectal and female breast), 4187 cardiovascular diseases/coronary heart disease (CVD/CHD), 856 violent deaths and injuries. Lifetime alcohol use was assessed at recruitment. RESULTS HRs comparing extreme drinkers (≥30 g/day in women and ≥60 g/day in men) to moderate drinkers (0.1-4.9 g/day) were 1.27 (95% CI 1.13 to 1.43) in women and 1.53 (1.39 to 1.68) in men. Strong associations were observed for ARC mortality, in men particularly, and for violent deaths and injuries, in men only. No associations were observed for CVD/CHD mortality among drinkers, whereby HRs were higher in never compared to moderate drinkers. Overall mortality seemed to be more strongly related to beer than wine use, particularly in men. The 10-year risks of overall death for women aged 60 years, drinking more than 30 g/day was 5% and 7%, for never and current smokers, respectively. Corresponding figures in men consuming more than 60 g/day were 11% and 18%, in never and current smokers, respectively. In competing risks analyses, mortality due to CVD/CHD was more pronounced than ARC in men, while CVD/CHD and ARC mortality were of similar magnitude in women. CONCLUSIONS In this large European cohort, alcohol use was positively associated with overall mortality, ARC and violent death and injuries, but marginally to CVD/CHD. Absolute risks of death observed in EPIC suggest that alcohol is an important determinant of total mortality.

Popliteal pseudoaneurysm after unicompartmental knee replacement: a case report.

Popliteal pseudoaneurysm is a rare but important complication of knee arthroplasties. To our knowledge, this complication has not been reported previously in the literature after unicompartmental knee arthroplasty. Apart from intraoperatively caused arterial injuries, obese patients and other previous cardiovascular diseases may be potential factors of risks for pseudoaneurysm in knee surgeries. As it is an uncommon complication and it has inconspicuous symptoms, both diagnosis and treatment can be delayed. This means that a high level of suspicion is necessary to prevent serious complications derived from pseudoaneurysms. LEVEL OF EVIDENCE Level IV.

Cardiac perforation after surgical repair of pectus excavatum.

Five days after surgical repair of pectus excavatum, this 7-year-old boy had a right-sided Kirschner wire protruding beneath the skin. The wire was repositioned blindly. Severe congestive heart failure developed. Surgical exploration showed a pierced right atrium, a torn septal leaflet of the tricuspid valve and noncoronary aortic cusp, and a large traumatic ventricular septal defect. The outcome and the indications and possible complications of surgery are discussed.

Efecto del phlebodium decumanum y de la coenzima q10 sobre el rendimiento deportivo en jugadores profesionales de voleibol

INTRODUCTION: Physical training programmes are based on provoking transitory states of fatigue in order to induce super compensation by the biological systems involved in the activity, in order to improve the athlete's medium-long term performance. The administration of nutritional supplements with antioxidant and immunomodulatory properties, such as Phlebodium decumanum and coenzyme Q10, can be a very advantageous means of achieving recovery from the inflammation and tissue damage caused by the stress of prolonged, intense exercise. METHODOLOGY: An experimental, longitudinal, double- blind experiment was conducted, with three randomised groups obtained from a sample of 30 male volleyball players (aged 22-32 years) at the University of Granada, with a high level of training (17 hours a week during the 6 months preceding the study). The effects were then evaluated of a month-long physical training programme, common to all the study groups, associated with the simultaneous administration of the following nutritional supplements: Phlebodium decumanum (4 capsules of 400 mg/capsule, daily), Experimental Group 1; Phlebodium decumanum (same dose andchedule as Group 1) plus coenzyme Q10 (4 capsules of 30 mg/ capsule, daily), Experimental Group 2; a placebo substance, Control Group. The following dependent blood variables were examined to assess the effects of the intervention on the basal immune and endocrine-metabolic profile: cortisol and interleukin-6, both related to the axis of exercise-induced stress; and lactic acid and ammonium, related essentially to the anaerobic metabolism of energy. RESULTS: All the study groups presented favourable adaptive changes with respect to the endocrine-metabolic and immune profile, as reflected by a significant decrease in the post-test concentrations of cortisol, interleukin 6, lactic acid and ammonium, compared to the values recorded before the physical activity with/without nutritional supplement, per protocol. The groups that achieved the most favourable profile were those which had received nutritional supplementation, rather than the placebo, and among the former, those which had received the double- strength supplement with Phlebodium decumanum plus coenzyme Q10. CONCLUSIONS: The intake of Phlebodium decumanum plus coenzyme Q10 for 4 weeks produced protective effects on the endocrine-metabolic and immune profile, which we attribute to the immunomodulatory and antioxidant properties of these substances, which are highly beneficial not only in terms of delaying fatigue and improving athletic performance, but also in reducing the risk of injuries associated with high intensity exercise.

Prótesis unicompartimental lateral de rodilla. Indicaciones, técnica y resultados a mediocorto plazo

Objectives: In patients with lateral osteoarthritis of the knee, use of external unicompartmental knee arthroplasty it is a well known surgical alternative, used by the minor trauma involved, short hospital stay and rapid recovery. The purpose of this study is to show the clinical outcomes to short-medium term of patients undergoing this procedure. Methods: we describe the technique used and the peculiarities of the prosthesis (A Mobile-bearing lateral unicompartmental knee replacement, Oxford Domed ®). This is an observational retrospective longitudinal study, of 15 arthroplasties performed in 13 women and 2 men, between 2010 and 2013, with a mean age of 60’7 years, with a diagnosis of lateral osteoarthritis of the knee, without involvement of the medial or patellofemoral compartment and cruciate ligaments functionally intact, with a mean follow up of 25 months. All patients complete the Oxford Knee Score and Visual Analog Scale (VAS) during the study. Results: The results are favorable, with an improvement of 6.60 points on the EVA, 3.73 for 1 in the postoperatory funcionality, the OKS very satisfactory with an average of 38 points over 50 and without any postoperative function surgical revision. Anserine tendinitis was observed in 20% of cases. Conclusions: The benefits of this surgery against their alternatives are assessed, and their potential drawbacks. External unicompartmental knee arthroplasty is an effective alternative in cases of knee osteoarthritis of the lateral compartment with no other associated injuries.

Comparative review of vertebroplasty and kyphoplasty.

The aim of this review is to compare the effectiveness of percutaneous vertebroplasty and kyphoplasty to treat pain and improve functional outcome from vertebral fractures secondary to osteoporosis and tumor conditions. In 2009, two open randomized controlled trials published in the New England Journal of Medicine questioned the value of vertebroplasty in treating vertebral compression fractures. Nevertheless, the practice of physicians treating these conditions has barely changed. The objective of this review is to try to clarify the most important issues, based on our own experience and the reported evidence about both techniques, and to guide towards the most appropriate choice of treatment of vertebral fractures, although many questions still remain unanswered.

Carotid artery rupture and cervicofacial actinomycosis.

Cervicofacial actinomycosis is an uncommon, progressive infection caused by bacilli of the Actinomyces genus. Actinomyces are common commensal saprophytes in the oral cavity which may have medical importance as facultative pathogens. Subsequent to local injuries to the oral mucosa, they may penetrate the deep tissues and be responsible for suppurative or granulomatous infections. We herein report a case of a 65-year-old man who underwent surgery followed by chemotherapy and radiotherapy for a tonsillar carcinoma. An ulcerous lesion in the base of the tongue developed and spread to the carotid artery wall. The man died of a massive hemorrhage due to left carotid artery rupture. Postmortem computed tomography angiography performed prior to autopsy allowed the precise localization of the source of bleeding to be detected. Postmortem biochemical investigations confirmed the presence of inflammation associated with local bacterial infection. Histological investigations revealed the rupture of the left carotid artery surrounded by numerous colonies of Actinomyces. Acute and chronic inflammation with tissue necrosis as well as post-actinic, fibrotic changes were also found in the tissues surrounding the ruptured artery wall.

Nasal trauma due to continuous positive airway pressure in neonates.

PATIENTS: All neonates admitted between January 2002 and December 2007 treated by nCPAP were eligible. METHODS: Patients' noses were monitored during nCPAP. Nasal trauma was reported into three stages: (I) persistent erythema; (II) superficial ulceration; and (III) necrosis. RESULTS: 989 neonates were enrolled. Mean gestational age was 34 weeks (SD 4), mean birth weight 2142 g (SD 840). Nasal trauma was reported in 420 (42.5%) patients and it was of stage I, II and III in 371 (88.3%), 46 (11%) and 3 (0.7%) patients, respectively. Incidence and severity of trauma were inversely correlated with gestational age and birth weight. The risk of nasal trauma was greater in neonates <32 weeks of gestational age (OR 2.48, 95% CI 1.59 to 3.86), weighing <1500 g at birth (OR 2.28, 95% CI 1.43 to 3.64), treated >5 days by nCPAP (OR 5.36, 95% CI 3.82 to 7.52), or staying >14 days in the NICU (OR 1.67, 95% CI 1.22 to 2.28). Most cases of nasal trauma (90%) appeared during the first 6 days of nCPAP. Persistent visible scars were present in two cases. CONCLUSIONS: Nasal trauma is a frequent complication of nCPAP, especially in preterm neonates, but long-term cosmetic sequelae are very rare. This study provides a description of nasal trauma and proposes a simple staging system. This could serve as a basis to develop strategies of prevention and treatment of this iatrogenic event.

Trends in socioeconomic inequalities in preventable mortality in urban areas of 33 Spanish cities, 1996-2007 (MEDEA project).

Abstract Background: Preventable mortality is a good indicator of possible problems to be investigated in the primary prevention chain, making it also a useful tool with which to evaluate health policies particularly public health policies. This study describes inequalities in preventable avoidable mortality in relation to socioeconomic status in small urban areas of thirty three Spanish cities, and analyses their evolution over the course of the periods 1996–2001 and 2002–2007. Methods: We analysed census tracts and all deaths occurring in the population residing in these cities from 1996 to 2007 were taken into account. The causes included in the study were lung cancer, cirrhosis, AIDS/HIV, motor vehicle traffic accidents injuries, suicide and homicide. The census tracts were classified into three groups, according their socioeconomic level. To analyse inequalities in mortality risks between the highest and lowest socioeconomic levels and over different periods, for each city and separating by sex, Poisson regression were used. Results: Preventable avoidable mortality made a significant contribution to general mortality (around 7.5%, higher among men), having decreased over time in men (12.7 in 1996–2001 and 10.9 in 2002–2007), though not so clearly among women (3.3% in 1996–2001 and 2.9% in 2002–2007). It has been observed in men that the risks of death are higher in areas of greater deprivation, and that these excesses have not modified over time. The result in women is different and differences in mortality risks by socioeconomic level could not be established in many cities. Conclusions: Preventable mortality decreased between the 1996–2001 and 2002–2007 periods, more markedly in men than in women. There were socioeconomic inequalities in mortality in most cities analysed, associating a higher risk of death with higher levels of deprivation. Inequalities have remained over the two periods analysed. This study makes it possible to identify those areas where excess preventable mortality was associated with more deprived zones. It is in these deprived zones where actions to reduce and monitor health inequalities should be put into place. Primary healthcare may play an important role in this process.

Peritalar dislocations: a retrospective study of 18 cases.

The purpose of this study is to retrospectively evaluate 18 consecutive cases of peritalar dislocations referred to our department during a period of 25 years and to delineate the factors influencing long-term prognosis. There were 13 (73%) medial and 5 (27%) lateral dislocations. Six patients (33%) suffered an open injury, including 2 of 13 (15%) medial and 4 of 5 (80%) lateral dislocations. Associated fractures involving the hindfoot or forefoot were noted in 7 feet, including 3 of 5 lateral dislocation cases. Reduction was accomplished under general anesthesia; in no case was open reduction necessary. In 4 of 6 open injuries with associated fractures, temporary fixation with Kirschner wires was performed. Patients were immobilized in a plaster cast for 4 weeks, or for 6 weeks in the presence of fracture, followed by weightbearing as tolerated. At a mean follow-up of 10.2 years (range, 4 to 26 years), 10 patients (56%) showed excellent results; all had sustained a closed medial low-energy dislocation. There were 3 cases (17%) with fair results and 5 cases (28%) with poor results. Forty-five percent of patients showed a restriction of activity, a reduction of subtalar range of motion, and moderate or severe radiographic signs of hindfoot degenerative arthritis. There were no cases of talar avascular necrosis, and in no case was secondary surgery necessary. Lateral dislocation and open medial dislocations with concomitant fractures showed a greater potential for poor prognosis. The results were independent from period of cast immobilization, suggesting that 4 to 6 weeks of immobilization provides acceptable long-term results.

Predictors of return to work after a knee injury in patients hospitalized in vocational rehabilitation

Introduction.- Knee injuries are frequent in a young and active population. Most of the patients resume their professional activity but few studies were interested in factors that predict a return to work. The aim of this study is to identify these predictors from a large panel of bio-psychosocial variables. We postulated that the return to work 3 months and 2 years after discharge is mostly predicted by psychosocial variables.Patients and methods.- Prospective study, patients hospitalized for a knee injury. Variables measured: the abbreviated injury score (AIS) for the gravity of the injuries, analog visual scale for the intensity of pain, INTERMED for the bio-psychosocial complexity, SF-36 for the quality of life, HADs for the anxiety/depression symptoms and IKDC score for the knee function. Univariate logistic regressions, adjusted for age and gender, were performed in order to predict return to work.Results.- One hundred and twenty-six patients hospitalized during 8 months after the accident were included into this prospective study. A total of 73 (58%) and 75 (59%) questionnaires were available after 3 months and 2 years, respectively. The SF-36 pain was the sole predictor of return to work at 3 months (odds Ratio 1.06 [1.02-1.10], P = 0.01; for a one point increase) and 2 years (odds Ratio 1.06 [1.02-1.10], P = 0.01). At three months, other factors are SF-36 (physic sub-scale), IKDC score, the presence of a work contract and the presence of litigation. The bio-psychosocial complexity, the presence of depressive symptoms predicts the return to work at two years.Discussion.- Our working hypothesis was partially confirmed: some psychosocial factors (i.e. depressive symptoms, work contract, litigation, INTERMED) predict the return to work but the physical health and the knee function, perceived by the patient, are also correlated. Pain is the sole factor isolated at both times (i.e. 3 months and 2 years) and, consequently, appears a key element in the prediction of the return to work. Some factors are accessible to the rehabilitation program but only if an interdisciplinary approach is performed.

Glucose-dependent insulinotropic polypeptide (GIP) and its receptor (GIPR): cellular localization, lesion-affected expression, and impaired regenerative axonal growth.

Glucose-dependent insulinotropic polypeptide (GIP) was initially described to be rapidly regulated by endocrine cells in response to nutrient ingestion, with stimulatory effects on insulin synthesis and release. Previously, we demonstrated a significant up-regulation of GIP mRNA in the rat subiculum after fornix injury. To gain more insight into the lesion-induced expression of GIP and its receptor (GIPR), expression profiles of the mRNAs were studied after rat sciatic nerve crush injury in 1) affected lumbar dorsal root ganglia (DRG), 2) spinal cord segments, and 3) proximal and distal nerve fragments by means of quantitative RT-PCR. Our results clearly identified lesion-induced as well as tissue type-specific mRNA regulation of GIP and its receptor. Furthermore, comprehensive immunohistochemical stainings not only confirmed and exceeded the previous observation of neuronal GIP expression but also revealed corresponding GIPR expression, implying putative modulatory functions of GIP/GIPR signaling in adult neurons. In complement, we also observed expression of GIP and its receptor in myelinating Schwann cells and oligodendrocytes. Polarized localization of GIPR in the abaxonal Schwann cell membranes, plasma membrane-associated GIPR expression of satellite cells, and ependymal GIPR expression strongly suggests complex cell type-specific functions of GIP and GIPR in the adult nervous system that are presumably mediated by autocrine and paracrine interactions, respectively. Notably, in vivo analyses with GIPR-deficient mice suggest a critical role of GIP/GIPR signal transduction in promoting spontaneous recovery after nerve crush, insofar as traumatic injury of GIPR-deficient mouse sciatic nerve revealed impaired axonal regeneration compared with wild-type mice.

Light-induced retinal degeneration correlates with changes in iron metabolism gene expression, ferritin level, and aging.

PURPOSE: Retinal degeneration is associated with iron accumulation in several rodent models in which iron-regulating proteins are impaired. Oxidative stress is catalyzed by unbound iron. METHODS: The role of the heavy chain of ferritin, which sequesters iron, in regulating the thickness of the photoreceptor nuclear layer in the 4- and 16-month-old wild-type H ferritin (HFt(+/+)) and heterozygous H ferritin (HFt(+/-)) mice was investigated, before and 12 days after exposure to 13,000-lux light for 24 hours. The regulation of gene expression of the various proteins involved in iron homeostasis, such as transferrin, transferrin receptor, hephaestin, ferroportin, iron regulatory proteins 1 and 2, hepcidin, ceruloplasmin, and heme-oxygenase 1, was analyzed by quantitative (q)RT-PCR during exposure (2, 12, and 24 hours) and 24 hours after 1 day of exposure in the 4-month-old HFt(+/+) and HFt(+/-) mouse retinas. RESULTS: Retinal degeneration in the 4-month-old HFt(+/-) mice was more extensive than in the HFt(+/+) mice. Yet, it was more extensive in both of the 16-month-old mouse groups, revealing the combined effect of age and excessive light. Injury caused by excessive light modified the temporal gene expression of iron-regulating proteins similarly in the HFt(+/-) and HFt(+/+) mice. CONCLUSIONS: Loss of one allele of H ferritin appears to increase light-induced degeneration. This study highlighted that oxidative stress related to light-induced injury is associated with major changes in gene expression of iron metabolism proteins.
