Health-related quality of life in non-alcoholic fatty liver disease: A cross-cultural study between Spain and the United Kingdom.

BACKGROUND: It is unclear what biopsychosocial factors influence the impact of NAFLD on health-related quality of life (HRQoL), and if these factors are equally important predictors between different nationalities. METHODS: HRQoL (CLDQ) was measured in both Southern European (Spain, n = 513) and Northern European (United Kingdom -UK-, n = 224) cohorts of patients with NAFLD in this cross-sectional study. For each cohort, participant data were recorded on histological grade of steatohepatitis, stage of fibrosis and biopsychosocial variables. Regression analysis was used to explore which of these variables predicted HRQoL. Moderated mediation models were conducted using SPSS PROCESS v3.5 macro. RESULTS: Participants with severe fibrosis reported more fatigue, systemic symptoms and worry, and lower HRQoL than those with none/mild fibrosis, regardless of place of origin. In addition, body mass index (BMI) and gender were found to be significant predictors of HRQoL in both Spanish and UK participants. Female gender was associated with worse emotional function, higher BMI and more fatigue, which predicted lower participants' HRQoL. UK participants showed more systemic symptoms and worry than Spanish participants, regardless of liver severity. The negative effects of gender on HRQoL through emotional function, BMI and fatigue were reported to a greater degree in UK than in Spanish participants. CONCLUSIONS: UK participants showed a greater impairment in HRQoL as compared to Spanish participants. Higher fibrosis stage predicted lower HRQoL, mainly in the Spanish cohort. Factors such as female gender or higher BMI contributed to the impact on HRQoL in both cohorts of patients and should be considered in future multinational intervention studies in NAFLD.

Shortcuts of Freely Relaxing Systems Using Equilibrium Physical Observables.

Many systems, when initially placed far from equilibrium, exhibit surprising behavior in their attempt to equilibrate. Striking examples are the Mpemba effect and the cooling-heating asymmetry. These anomalous behaviors can be exploited to shorten the time needed to cool down (or heat up) a system. Though, a strategy to design these effects in mesoscopic systems is missing. We bring forward a description that allows us to formulate such strategies, and, along the way, makes natural these paradoxical behaviors. In particular, we study the evolution of macroscopic physical observables of systems freely relaxing under the influence of one or two instantaneous thermal quenches. The two crucial ingredients in our approach are timescale separation and a nonmonotonic temperature evolution of an important state function. We argue that both are generic features near a first-order transition. Our theory is exemplified with the one-dimensional Ising model in a magnetic field using analytic results and numerical experiments.

Global survey of stigma among physicians and patients with nonalcoholic fatty liver disease.

BACKGROUND & AIMS: Patients with fatty liver disease may experience stigma from the disease or comorbidities. In this cross-sectional study, we aimed to understand stigma among patients with nonalcoholic fatty liver disease (NAFLD)/nonalcoholic steatohepatitis (NASH) and healthcare providers. METHODS: Members of the Global NASH Council created two surveys about experiences/attitudes toward NAFLD and related diagnostic terms: a 68-item patient and a 41-item provider survey. RESULTS: Surveys were completed by 1,976 patients with NAFLD across 23 countries (51% Middle East/North Africa [MENA], 19% Europe, 17% USA, 8% Southeast Asia, 5% South Asia) and 825 healthcare providers (67% gastroenterologists/hepatologists) across 25 countries (39% MENA, 28% Southeast Asia, 22% USA, 6% South Asia, 3% Europe). Of all patients, 48% ever disclosed having NAFLD/NASH to family/friends; the most commonly used term was "fatty liver" (88% at least sometimes); "metabolic disease" or "MAFLD" were rarely used (never by >84%). Regarding various perceptions of diagnostic terms by patients, there were no substantial differences between "NAFLD", "fatty liver disease (FLD)", "NASH", or "MAFLD". The most popular response was being neither comfortable nor uncomfortable with either term (56%-71%), with slightly greater discomfort with "FLD" among the US and South Asian patients (47-52% uncomfortable). Although 26% of patients reported stigma related to overweight/obesity, only 8% reported a history of stigmatization or discrimination due to NAFLD. Among providers, 38% believed that the term "fatty" was stigmatizing, while 34% believed that "nonalcoholic" was stigmatizing, more commonly in MENA (43%); 42% providers (gastroenterologists/hepatologists 45% vs. 37% other specialties, p = 0.03) believed that the name change to metabolic dysfunction-associated steatotic liver disease (or MASLD) might reduce stigma. Regarding the new nomenclature, the percentage of providers reporting "steatotic liver disease" as stigmatizing was low (14%). CONCLUSIONS: The perception of NAFLD stigma varies among patients, providers, geographic locations and sub-specialties. IMPACT AND IMPLICATIONS: Over the past decades, efforts have been made to change the nomenclature of nonalcoholic fatty liver disease (NAFLD) to better align with its underlying pathogenetic pathways and remove any potential stigma associated with the name. Given the paucity of data related to stigma in NAFLD, we undertook this global comprehensive survey to assess stigma in NAFLD among patients and providers from around the world. We found there is a disconnect between physicians and patients related to stigma and related nomenclature. With this knowledge, educational programs can be developed to better target stigma in NAFLD among all stakeholders and to provide a better opportunity for the new nomenclature to address the issues of stigma.

Centriolin interacts with HectD1 in a cell cycle dependent manner.

OBJECTIVE: The centrosome is universally recognized as the microtubule organizing center of animal cells, but emerging evidence suggests that it has other important functions including primary cilia formation, DNA damage checkpoints, and cell cycle progression. Despite this, the role of individual components of the centrosome remains unclear. Previous studies suggest that one component, centriolin, has an important function in cytokinesis and cell cycle progression, although its exact role in these processes is not known. To determine how centriolin influences the progression through the cell cycle, we sought to identify interacting partners that may be involved in regulating its function. RESULTS: This study provides evidence that the ubiquitin E3 ligase HectD1 binds to centriolin and that this association likely accounts for our observation that HectD1 co-localizes with centriolin at the centrosome during mitosis. In addition to its centrosomal localization, we also show that the expression of HectD1 fluctuates throughout the cell cycle, with the highest levels during mitosis, coinciding with a marked reduction in centriolin expression. We propose that the interaction between HectD1 and centriolin may be necessary for normal cell cycle progression and we speculate that this function may involve HectD1-mediated degradation of centriolin.

Improved health-related quality of life with semaglutide in people with non-alcoholic steatohepatitis: A randomised trial.

BACKGROUND: Non-alcoholic steatohepatitis (NASH) can adversely affect health-related quality of life (HRQoL). AIMS: This double-blind, placebo-controlled, phase 2 trial aimed to report the effects of the glucagon-like peptide-1 receptor agonist, semaglutide, on HRQoL in patients with NASH as a secondary endpoint. METHODS: Adults with biopsy-proven NASH and stage 1-3 fibrosis were randomised (3:3:3:1:1:1) to once-daily subcutaneous semaglutide 0.1, 0.2 or 0.4 mg, or placebo, for 72 weeks. Patients were invited to complete the Short Form-36 version 2.0 questionnaire at weeks 0, 28, 52 and 72. RESULTS: Between January 2017 and September 2018, 320 patients were enrolled. At 72 weeks, semaglutide was associated with significant improvements in physical component summary (PCS) score (estimated treatment difference [ETD] 4.26; 95% confidence interval [CI]: 1.96-6.55; p = 0.0003); bodily pain (ETD 5.07; 95% CI: 2.15-7.99; p = 0.0007); physical functioning (ETD 3.51; 95% CI: 1.16-5.86; p = 0.0034); role limitations due to physical health problems (ETD 2.80; 95% CI: 0.28-5.33; p = 0.0294); social functioning (ETD 3.16; 95% CI: 0.53-5.78; p = 0.0183) and vitality (ETD 4.47; 95% CI: 1.63-7.32; p = 0.0021). There was no significant difference in the mental component summary score (ETD 1.02; 95% CI: -1.59 to 3.62; p = 0.4441). After 72 weeks, improvements in PCS scores were significantly greater in patients (pooled semaglutide and placebo) with NASH resolution than without (p = 0.014). CONCLUSIONS: Treatment with semaglutide is associated with improvements in the physical components of HRQoL in patients with biopsy-proven NASH and fibrosis compared with placebo.

Significance of Post-Traumatic Growth and Mental Health for Coping in Multiple Sclerosis Caregivers.

We investigated the influence of post-traumatic growth (PTG) and mental health (MH) on multiple sclerosis (MS) caregivers' uses of coping strategies and identified biopsychosocial predictors of proactive or reactive coping. The Short Form Health Survey (SF-12), General Health Questionnaire (GHQ-28), Post-Traumatic Growth Inventory (PGI-21), Brief COPE Questionnaire (COPE-28), and Multidimensional Scale of Perceived Social Support (MSPSS) were used to evaluate 209 caregivers. Higher PTG was related to greater use of emotional support, positive reframing, religion, active coping, instrumental support, planning, denial, self-distraction, self-blaming, and venting. Better MH was associated with greater use of acceptance, while behavioral disengagement and self-distraction were associated with poorer MH. The PTG dimensions relating to others and new possibilities, SF-12 dimensions of physical and emotional roles as well as partnership, not living with the patient, and significant others' social support were predictors of proactive coping. Reactive coping was positively predicted by the PTG dimension relating to others, depression, vitality, other than partner relation, and physical role, and negatively predicted by mental health level and emotional role. In summary, higher MH was associated with proactive coping strategies, whereas post-traumatic growth was related to the use of a wide range of proactive coping as well as reactive coping strategies.

Sordera súbita idiopática: factores pronóstico y resultados del tratamiento de rescate con dexametasona intratimpánica / Idiopathic sudden sensorineural hearing loss: prognostic factors and outcomes of salvage treatment with intratympanic dexamethasone

Introducción y objetivos: La sordera súbita idiopática se define habitualmente, como una pérdida auditiva superior o igual a 30 dB HL, en 3 o más frecuencias consecutivas, con un tiempo de instauración inferior a 72 horas, de causa desconocida. Siendo actualmente motivo de discusión el efecto de la terapia esteroidea en este síndrome, evaluaremos la eficacia del corticoide intratimpánico (CIT) como tratamiento de rescate. Como objetivo secundario, estudiaremos la influencia de determinados factores considerados de riesgo o pronóstico. Pacientes y métodos: Se comparan los resultados de dos grupos de población con edad y pérdida auditiva similar. El primero, de 99 pacientes, recibió exclusivamente tratamiento sistémico con corticoides. En el segundo de 70, con una sordera súbita idiopática refractaria al tratamiento general, instilamos corticoide intratimpánico. Comparamos las diferencias de umbral medio auditivo en el momento del diagnóstico y a los 3 meses, además del grado general de recuperación. Resultados: La aplicación intratimpánica de 3 dosis de dexametasona (8mg/ml) en la sordera súbita idiopática refractaria, no ha producido, en nuestra población, un cambio significativo respecto al tratamiento sistémico. Analizamos también la influencia de los factores pronósticos seleccionados. Discusión: Desconocemos la eficacia del tratamiento con corticoides en la sordera súbita idiopática. El tipo de lesión y las características del paciente podrían ser decisivos en el pronóstico final y en el resultado terapéutico. Conclusiones: El tratamiento de rescate con CIT, no ha aportado mejoría auditiva significativa en la población estudiada. Los factores con peor pronóstico son: la presencia de síntomas vestibulares, la hipoacusia de grado profundo, la caída audiométrica hacia tonos agudos, el inicio del tratamiento después de 2 semanas y fundamentalmente, la falta de mejoría de al menos 10 dB el 4º día de tratamiento. (AU)

Introduction and objectives: Idiopathic Sudden Sensorineural Hearing Loss (ISSNHL) is commonly defined as greater than 30 dB of hearing loss in at least 3 audiometric frequencies occurring over 3 days or less, of unknown cause. Since the effect of steroid therapy in this syndrome is currently under discussion, we will evaluate the efficacy of intratympanic corticosteroid (ITC) as rescue treatment. As a secondary objective, we will study the influence of certain factors considered risk or prognostic. Patients and methods: The results of two population groups with similar age and hearing loss are compared. The first of 99 patients received exclusively systemic treatment with corticosteroids. In the second group of 70, with ISSNHL refractory to general treatment, we instilled intratympanic corticosteroids. We compared the differences in mean hearing threshold at diagnosis and at 3 months, as well as the general degree of recovery. Results: Intratympanic application of 3 doses of dexamethasone (8mg/ml) in refractory ISSNHL did not produce, in our population, a significant change with respect to systemic treatment. We also analyzed the influence of selected prognostic factors. Discussion: We do not know the efficacy of corticosteroid treatment in idiopathic sudden deafness. The type of lesion and patient characteristics could be decisive in the final prognosis and therapeutic outcome. Conclusions: Rescue treatment with ITC has not provided significant hearing improvement in the population studied. The factors with the worst prognosis are the presence of vestibular symptoms, profound hearing loss, high-frequency hearing loss in audiometry, the beginning of treatment after 2 weeks and fundamentally, the lack of improvement of at least 10 dB on the 4th day of treatment.

Vitality, mental health and role-physical mediate the influence of coping on depressive symptoms and self-efficacy in patients with non-alcoholic fatty liver disease: A cross-sectional study.

OBJECTIVE: Our aim was to determine whether the association between active coping and depressive symptoms in patients with non-alcoholic fatty liver disease (NAFLD) was mediated by vitality, and whether diabetes and obesity could impact on this relationship. We also wanted to find out whether mental health and role-physical modulated the relationship between passive/avoidance coping and self-efficacy, and the role of liver fibrosis. METHODS: Depressive symptoms (BDI-II), self-efficacy (GSE), coping (COPE-28) and quality of life (SF-12) were evaluated in 509 biopsy-proven NAFLD patients in this cross-sectional study. Mediation and moderated mediation models were conducted using the SPSS PROCESS v3.5 macro. RESULTS: Vitality mediated the relationship between active coping and depressive symptoms (-2.254, CI = -2.792 to -1.765), with diabetes (-0.043, p = 0.017) and body mass index (BMI) (-0.005, p = 0.009) moderating the association. In addition, mental health (-6.435, CI = -8.399 to -4.542) and role-physical (-1.137, CI = -2.141 to -0.315) mediated the relationship between passive/avoidance coping and self-efficacy, with fibrosis stage (0.367, p < 0.001) moderating this association. Specifically, the presence of diabetes and significant fibrosis, and a higher BMI, were associated with greater negative impact on participant depressive symptoms or self-efficacy. CONCLUSION: A maladaptive coping style was associated with poorer vitality, mental health and role-physical in NAFLD patients, which along with the presence of metabolic comorbidity (diabetes and obesity) and significant fibrosis predicted more depressive symptoms or poorer self-efficacy in these patients. These results suggested incorporating emotional and cognitive evaluation and treatment in patients with NAFLD.

Tricofoliculoma del conducto auditivo externo. Un caso excepcional de presentación agresiva / Trichofolliculoma of the external auditory canal, an exceptional case of aggressive presentation

Introducción: El tricofoliculoma es una tumoración anexial, infrecuente y benigna, de los folículos pilosos, cuya localización en el conducto auditivo externo (CAE) es excepcional. Objetivo: Describir y actualizar, las características clínicas y evolutivas del tricofoliculoma del CAE a través de un caso clínico. Caso clínico: Mujer de 47 años con una tumoración agresiva del CAE, que destruía la mastoides, cuyo estudio histopatológico, tras la cirugía, ofreció el diagnóstico de tricofoliculoma, asociado a un colesteatoma, Discusión y conclusiones: El tricofoliculoma es un raro tumor de los folículos pilosos, cuya localización en el CAE es excepcional. El comportamiento agresivo del caso presentado quizá fuera debido a su asociación con un colesteatoma, de probable origen secundario. (AU)

Introduction and objective: Trichofolliculoma is a rare and benign adnexal tumour of the hair follicles. The location of this tumour in the external auditory canal (EAC) is exceptional. Its diagnosis is histopathological. Objective: Present an exceptional clinical case, the finding of a trichofolliculoma in the external auditory canal. Clinical case: We present the clinical case of a CAE trichofolliculoma that, when associated with a cholesteatoma, had an aggressive manifestation with destruction of the temporal bone. Conclusion: Trichofolliculoma is a rare tumour of the hair follicles whose location in the EAC is exceptional. The aggressive behaviour of the case presented was due to its association with a cholesteatoma, probably secondary to the obstruction and recurrent inflammatory processes of the tumour. (AU)

Slow growth of magnetic domains helps fast evolution routes for out-of-equilibrium dynamics.

Cooling and heating faster a system is a crucial problem in science, technology, and industry. Indeed, choosing the best thermal protocol to reach a desired temperature or energy is not a trivial task. Noticeably, we find that the phase transitions may speed up thermalization in systems where there are no conserved quantities. In particular, we show that the slow growth of magnetic domains shortens the overall time that the system takes to reach a final desired state. To prove that statement, we use intensive numerical simulations of a prototypical many-body system, namely, the two-dimensional Ising model.

Influence of Psychological Biomarkers on Therapeutic Adherence by Patients with Non-Alcoholic Fatty Liver Disease: A Moderated Mediation Model.

Our aim was to analyze whether depressive symptoms mediated the association between physical quality of life (QoL) and adherence to physical activity in patients with non-alcoholic fatty liver disease (NAFLD), as well as the association between social support and adherence to diet. We also examined whether self-efficacy exerted a moderating role in these associations. QoL (SF-12), social support (MSPSS), depressive symptoms (HADS), self-efficacy (GSE), physical activity (IPAQ) and diet (MEDAS) were evaluated in 413 biopsy-proven NAFLD patients. Mediation and moderated mediation models were conducted using the SPSS PROCESS v3.5 macro. Results showed that depressive symptoms mediated the relationship between physical QoL and adherence to physical activity (indirect effect = 6.248, CI = 1.917-10.727), as well as the relationship between social support and adherence to diet (indirect effect = 0.148, CI = 0.035-0.275). Self-efficacy also moderated the indirect effects of QoL and social support on therapeutic adherence through depressive symptoms. Specifically, the higher self-efficacy was, the lower the negative impact on the NAFLD patient's mental health. In conclusion, self-efficacy is defined as a protective factor for therapeutic adherence by NAFLD patients with a psychosocial risk profile. Self-efficacy should, therefore, be a main psychological target in future multidisciplinary NAFLD approaches.

Quality of Life and Coping in Nonalcoholic Fatty Liver Disease: Influence of Diabetes and Obesity.

Our aim was to analyze how type 2 diabetes and obesity influence quality of life (QoL) and coping in patients with nonalcoholic fatty liver disease (NAFLD), and which coping strategies predict diabetic or obese participants' QoL. QoL (SF-12, CLDQ-NAFLD) and coping strategies (COPE-28) were evaluated in 307 biopsy-proven NAFLD patients with absence or presence of diabetes or obesity. QoL was compared with normality tables for the general Spanish population. Interactive effects were found in physical functioning (p = 0.008), role-physical (p = 0.016) and activity (p = 0.014). Diabetic patients reported worse scores when they were also obese and vice versa, that is, obese patients scored worse when they were also diabetic. Both diabetic and obese patients had lower QoL than those without metabolic pathology or the general population, and obese patients also reported more passive/avoidance coping. Active coping, positive reframing and acceptance predicted better QoL, while denial, self-blame, self-distraction, disengagement and religion predicted lower QoL. In conclusion, diabetes and obesity were associated with lower QoL in patients with NAFLD. Obesity was also associated with more passive/avoidance coping. Furthermore, passive/avoidance coping strategies predicted lower QoL than active, recommending modification of maladaptive coping strategies in future multidisciplinary NAFLD treatments.

Psychological Biomarkers and Fibrosis: An Innovative Approach to Non-alcoholic Fatty Liver Disease.

Background: It is unknown how perceived social support and the progression of liver damage influence the psychosocial profile of patients with non-alcoholic fatty liver disease (NAFLD). In the present study, we therefore investigated which biomarkers influence the quality of life, mental health, and coping strategies of NAFLD patients. Methods: Quality of life (SF-12 and CLDQ-NAFLD), mental health (HADS and BDI-II), and coping strategies (COPE-28) were evaluated by high or low perceived social support (MSPSS) and the presence of non-alcoholic steatohepatitis (NASH) and significant fibrosis in 492 biopsy-proven NAFLD patients. The results were compared with quality of life normality tables for the general Spanish population. We also determined whether liver histology and biopsychosocial variables predicted participants' quality of life. Results: Interactive effects were found in vitality (p = 0.05), activity (p = 0.005), anxiety (p = 0.04), and denial (p = 0.04), with NASH patients showing a higher-risk biopsychosocial profile when they perceived less social support. Furthermore, patients with low perceived social support showed lower quality of life, worse mental health, and more maladaptive coping than those with high perceived social support, regardless of NASH presence. Patients with significant fibrosis showed lower quality of life compared to those without or the general Spanish population. Patients with significant fibrosis also reported worse mental health and more maladaptive coping. Lastly, significant fibrosis, female sex, greater anxiety and depressive symptoms, and worse physical and mental health-related quality of life were found to be independent determinants of worse disease-specific quality of life in these patients. Conclusions: Low perceived social support, significant fibrosis, and female sex were independently associated with a higher-risk psychosocial profile in NAFLD. These findings support the role of psychological biomarkers based on quality of life, mental health, and coping strategies in the management of these patients and suggest the potential benefits of a psychological intervention.

Phase diagram for the bisected-hexagonal-lattice five-state Potts antiferromagnet.

In this paper we study the phase diagram of the five-state Potts antiferromagnet on the bisected-hexagonal lattice. This question is important since Delfino and Tartaglia recently showed that a second-order transition in a five-state Potts antiferromagnet is allowed, and the bisected-hexagonal lattice had emerged as a candidate for such a transition on numerical grounds. By using high-precision Monte Carlo simulations and two complementary analysis methods, we conclude that there is a finite-temperature first-order transition point. This one separates a paramagnetic high-temperature phase, and a low-temperature phase where five phases coexist. This phase transition is very weak in the sense that its latent heat (per edge) is two orders of magnitude smaller than that of other well-known weak first-order phase transitions.

A case of inflammatory pseudotumour of the gallbladder presenting as a big mass of uncertain behavior.

BACKGROUND: Inflammatory pseudotumour has been used to describe an inflammatory or fibrosing tumoral process of an undetermined cause that may involve a variety of organ systems, including the lungs, spleen, liver, lymph nodes, pancreas and extrahepatic bile duct with potential for recurrence and persistent local growth. In this article, we report a patient with a big mass of uncertain nature and behavior. CASE PRESENTATION: A 60-year-old woman presented with a 1-week history of abdominal pain, fever and jaundice. Six months before she had had right upper quadrant pain that was interpreted as biliary colic. A contrast-enhanced CT scan showed a big mass of soft tissue with diffuse infiltration of the gallbladder, displacement of the transverse colon, hepatic flexure and duodenum. For diagnostic distinction between a chronic inflammatory disease or a neoplasm, exploratory laparotomy was required. Intraoperative exploration disclosed a big mass of hard texture involving the gallbladder, with multiple concrements, hepatoduodenal ligament, right and transverse mesocolon, stomach and duodenum. Cholecystectomy was performed, preserving adjacent organs with macroscopic desmoplastic reaction. Histopathologic examination of the gallbladder showed a spindle cell proliferation with diffuse chronic inflammatory infiltrate of lymphocytes, plasma cells and hyalinized fibrous stroma. No vascular invasion or cellular atypia were evident. CONCLUSION: Inflammatory pseudotumour is a rare condition and diagnostic distinction from a chronic inflammatory disease or other neoplasm is only possible by histopathologic examination. There is a limited number of case reports in the literature indicating tumor location in the gallbladder.

Colesteatoma de conducto auditivo externo: estudio de una serie de casos / Cholesteatoma of the external auditory canal: case series study

INTRODUCCIÓN Y OBJETIVOS: El colesteatoma de conducto auditivo externo (CCAE) es un proceso patológico poco frecuente, caracterizado por la invasión de tejido escamoso en un área del canal auditivo, que progresa hasta la destrucción ósea. Debido a la escasez de casos publicados hemos considerado de utilidad esta revisión. MATERIAL Y MÉTODOS: Estudio prospectivo y observacional desde el año 2000, de 18 pacientes diagnosticados clínicamente de CCAE en nuestro servicio de ORL. RESULTADOS: El porcentaje de hombres y mujeres es similar, con una edad media de diagnóstico de 60 años. La localización más frecuente es póstero-inferior y en la mayor parte de casos el origen es primario. La otalgia, la otorrea y la hipoacusia fueron los síntomas principales, siendo menos habitual el prurito y excepcional la debilidad facial. En general el tratamiento es conservador, pero resultó necesario el abordaje quirúrgico en un tercio de pacientes mediante canaloplastia, siguiendo el esquema expuesto, o la mastoidectomía, en función de la extensión de las lesiones. CONCLUSIONES: Aunque desconocemos los mecanismos patogénicos responsables de la formación y desarrollo del CCAE, la inclusión de queratina entre el epitelio y el hueso, con la participación del periostio, parecen ser los desencadenantes del proceso. El diagnóstico es clínico y su extensión determina el empleo de un tratamiento local o quirúrgico, que suele ser resolutivo

INTRODUCTION: External auditory canal cholesteatoma (EACC) is a rare entity characterized by the invasion of squamous tissue in the auditory canal, that progresses to bone destruction. Due to the scarcity of published cases of EACC, we have deemed useful this review. MATERIAL AND METHODS: Prospective and observational study from the year 2000 to the present in 18 patients clinically diagnosed with EACC in our ORL service. RESULTS: The percentage of men and women is similar, with a mean age at diagnosis of 60 years. The most frequently location was postero-inferior, and in most cases, the origin is primary. Otalgia, otorrhea and subjective hearing loss were the main symptoms, being less common the pruritus and exceptional facial weakness. Overall, the treatment is conservative, but it was necessary surgical treatment on one-third of the patients, performing canaloplasty or mastoidectomy, according to the extent of injuries. CONCLUSIONS: Although we do not know the genesis and pathogenic mechanisms responsible of EACC formation and development, the inclusion of keratin between the epithelium and bone, with the participation of the periosteum, seems to be the trigger of this process. The diagnosis is clinical, and its extension determines the use of a local or surgical treatment, which is usually resolutive

Rehabilitación vestibular en la dependencia visual y somatosensorial / Vestibular rehabilitation for visual and somatosensory dependency

INTRODUCCIÓN: En la disfunción vestibular crónica es frecuente que se incremente el mareo o el desequilibrio con el propio movimiento o con el de un ambiente visual sobrecargado, lo que se denomina dependencia visual, que forma parte del síndrome de vértigo/mareo inducido visualmente. En otras ocasiones, la dependencia es somatosensorial y el paciente pierde con facilidad el equilibrio al alterarse la superficie de soporte. El objetivo de esta revisión es describir las características de la dependencia visual y somatosensorial y el modo de tratarlas. MÉTODO: Revisión narrativa. RESULTADOS: El vértigo visual se diagnostica clínicamente a través de los síntomas referidos por el paciente. Mediante la exposición a estímulos desencadenantes, el sistema nervioso central se habitúa, incrementando la tolerancia. El tratamiento utilizado se basa en la terapia física, la realidad virtual y la estimulación optocinética progresiva. CONCLUSIÓN/DISCUSIÓN: Aunque sigue siendo tema de discusión la naturaleza de las entradas visuales que determinan la estabilidad postural, el objetivo terapéutico consiste en desensibilizar al individuo del estímulo visual para mejorar su sintomatología

INTRODUCTION: In the patient with chronic vestibular dysfunction, it is very frequent to note more imbalance or dizziness produced by its own movement or the overloaded visual environment; this is called also visual dependence that is part of the visual vertigo syndrome. In other cases, like somatosensory dependence, the patient will lose balance easily when the support surface changes. The objective of this review was to describe the visual and somatosensory dependence patterns as well as how to treat them. METHOD: Narrative review. RESULTS: Visual vertigo is currently a clinical diagnosis based on the patient's history of disease presentation. Through repeated exposure to trigger stimuli, the central nervous system is able to increase tolerance and improve functional results. Traditional treatments for this disorder involve vestibular rehabilitation therapy, virtual reality simulators of moving objects, as well as graded exposure to optokinetic stimulation. DISCUSSION/CONCLUSION: Although the real nature of the visual cues for posture stabilization remains an open debate, the goal of therapy is to promote desensitization to visual stimuli and increase tolerance

Relationship Between Self-Perceived Health, Vitality, and Posttraumatic Growth in Liver Transplant Recipients.

Our objective was to analyze the differences in posttraumatic growth in 240 liver transplant recipients based on two factors. First, self-perceived health: better (Group 1 = G1) and worse (Group 2 = G2). Second, vitality: more (Group 3 = G3) and less (Group 4 = G4). The Posttraumatic Growth Inventory, SF-36 Health Survey (Item 2) and SF-12 Health Survey (vitality dimension) were used. Firstly, analyzing main effects recipients with better (G1) compared to worse (G2) self-perceived health, showed greater posttraumatic growth. Interaction effects were found on essential posttraumatic growth domains such as new possibilities (p = 0.040), personal strength (p = 0.027), and appreciation of life (p = 0.014). Statistically significant differences showed that among transplant recipients with worse self-perceived health (G2), those with more vitality had higher levels on abovementioned posttraumatic growth dimensions. However, in transplant recipients with better self-perceived health (G1) respective dimensions were not significantly influenced by the level of vitality. Among the recipients with less vitality (G4), those with better self-perceived health showed higher scores on abovementioned posttraumatic growth dimensions. We conclude that positive self-perceived health might compensate for a lack of vitality as well as a high level of vitality may compensate for negative self-perceived health regarding the development of crucial aspects of posttraumatic growth after liver transplantation.
