Design and validation of a patient-reported outcome measure scale in acute pancreatitis: the PAN-PROMISE study.

OBJECTIVE: This study aimed to develop and validate a patient-reported outcome measure (PROM) in acute pancreatitis (AP) as an endpoint centred on the patient. DESIGN: A PROM instrument (PAtieNt-rePoRted OutcoMe scale in acute pancreatItis, an international proSpEctive cohort study, PAN-PROMISE scale) was designed based on the opinion of patients, professionals and an expert panel. The scale was validated in an international multicentre prospective cohort study, describing the severity of AP and quality of life at 15 days after discharge as the main variables for validation. The COSMIN (COnsensus-based Standards for the selection of health status Measurement INstruments) methodology was applied. Both the design and validation stages considered the content and face validity of this new instrument; the metric properties of the different items, reliability (reproducibility and internal consistence), the construct, structural and criterion validity, responsiveness and interpretability of this scale. RESULTS: PAN-PROMISE consists of a seven-item scale based on the symptoms that cause the most discomfort and concern to patients with AP. The validation cohort involved 15 countries, 524 patients. The intensity of symptoms changed from higher values during the first 24 hours to lower values at discharge and 15 days thereafter. Items converged into a unidimensional ordinal scale with good fit indices. Internal consistency and split-half reliability at discharge were adequate. Reproducibility was confirmed using test-retest reliability and comparing the PAN-PROMISE score at discharge and 15 days after discharge. Evidence is also provided for the convergent-discriminant and empirical validity of the scale. CONCLUSION: The PAN-PROMISE scale is a useful tool to be used as an endpoint in clinical trials, and to quantify patient well-being during the hospital admission and follow-up. TRIAL REGISTRATION NUMBER: NCT03650062.

Vagus nerve stimulator implantation for epilepsy in a paediatric hospital: outcomes and effect on quality of life.

INTRODUCTION: Epilepsy, which is present in 0.5% to 1% of the paediatric population, is one of the most frequent childhood neurological disorders. Approximately 20% to 30% of these cases will be drug-resistant. The objective of this study is to describe the impact of vagal nerve stimulation (VNS) on seizures and quality of life in a sample of 30 patients. METHODS: Descriptive, retrospective study of all patients with a VNS device implanted between 2008 and 2013 in a single paediatric hospital, based on patients' medical records. Quality of life was assessed using the Spanish scale for quality of life in children with epilepsy, completed by means of a telephone interview. RESULTS: We describe a population of 19 boys (64%) and 11 girls (36%) with a mean age at seizure onset of 21 months (1-144 months). The mean age of VNS implantation was 11.89 years. Follow-up periods ranged from 6 to 36 months. Mean reduction in seizures at 6 months was 38%, with a reduction of 43% at 12 months, 42% at 24 months, and 54% at 36 months. At least half of all patients were classified as responders. According to the quality of life scale, 54% of the families rated the effect of VNS as either very good or good while 39% rated it as fair. CONCLUSIONS: VNS is a safe palliative treatment that is generally well tolerated. It is partially effective for controlling drug-resistant epilepsy and exerts a positive effect on quality of life.

[Breast hematoma masking a sarcoma]. / Hematoma mamario enmascarando un sarcoma.

Sarcomas account for less than 1% of malignant breast tumors. We present the case of a sarcoma (malignant fibrous histiocytoma) of the breast that debuted as a lump. The patient associated the lump with trauma, and the clinical, sonographic, and cytological findings were suggestive of a hematoma. The lump grew rapidly, and the follow-up sonogram one month later clearly revealed hypervascular solid poles. This atypical presentation is useful for reviewing the management of lesions suggestive of hematomas, which are often associated with nonspecific findings and occasionally with signs that raise suspicion of malignancy. The emergence of what appears to be a hematoma in the breast, even when accompanied by a history of trauma or a tendency toward bleeding, calls for prudence: very short-term follow-up and biopsy, even excisional biopsy, are recommended if the lesion does not evolve like a hematoma.

Non-arteritic anterior ischemic optic neuropathy as the only manifestation of a malignant hypertensive crisis: Report of a case.

Non-arteritic anterior ischemic optic neuropathy (NAION) is after glaucoma the most common optic neuropathy in patients over 50 years. It is known that high blood pressure (HBP) is an important risk factor for the development of NAION. It is also known that malignant arterial hypertension (MAH) could be accompanied by optic disc edema. However, MAH has not classically been considered a cause of NAION. We report the case of a 32-year-old patient who presented irreversible visual loss with a pattern compatible with NAION as the only manifestation of a hypertensive crisis.

Long anterior zonule trait, lessons learned about an uncommon form of secondary angle closure: a case report.

A 62-year-old black woman with uncontrolled chronic narrow-angle glaucoma on 3-drug therapy underwent phaco-non-perforating deep sclerectomy of her left eye. During surgery it was revealed that she had long zonule trait. She later required goniopuncture and conjuntival needling, presenting an iris herniation in the goniopuncture that could be reduced conservatively. Long anterior zonule trait should be suspected in those patients presenting with a combination of narrow angle and pigment dispersion syndrome. The management of ocular hypertension and glaucoma associated to this trait is not protocolized. This communication discusses on the best action in this rare form of glaucoma.

The costs of stroke in Spain by aetiology: the CONOCES study protocol.

INTRODUCTION: Patients with stroke associated with non-valvular atrial fibrillation (NVAF) are a specific group, and their disease has a considerable social and economic impact. The primary objective of the CONOCES study, the protocol of which is presented here, is to compare the costs of stroke in NVAF patients to those of patients without NVAF in Spanish stroke units from a societal perspective. MATERIALS AND METHODS: CONOCES is an epidemiological, observational, naturalistic, prospective, multicentre study of the cost of the illness in a sample of patients who have suffered a stroke and were admitted to a Spanish stroke unit. During a 12-month follow-up period, we record sociodemographic and clinical variables, score on the NIH stroke scale, level of disability, degree of functional dependency according to the modified Rankin scale, and use of healthcare resources (hospitalisation at the time of the first episode, readmissions, outpatient rehabilitation, orthotic and/or prosthetic material, medication for secondary prevention, medical check-ups, nursing care and formal social care services). Estimated monthly income, lost work productivity and health-related quality of life measured with the generic EQ-5D questionnaire are also recorded. We also administer a direct interview to the caregiver to determine loss of productivity, informal care, and caregiver burden. RESULTS AND CONCLUSIONS: The CONOCES study will provide more in-depth information about the economic and clinical impact of stroke according to whether or not it is associated with NVAF.

Rationale, design and methodology of TESEO study: a registry of thrombosis and neoplasia of SEOM (Spanish Society of Medical Oncology).

BACKGROUND AND RATIONALE: Thromboembolic complications are a serious, preventable and common event in cancer patients that contributes to increasing morbidity and mortality. Despite increasing knowledge on cancer-associated thrombosis (CAT), there are still several aspects of diagnosis, clinical management, treatment and prognosis with uncertainties that are under-represented in randomized clinical trials. For this reason, the Spanish Society of Medical Oncology (SEOM) launched in June 2018 a registry of CAT. METHODS/DESIGN: TESEO is an ongoing prospective, non-interventional, multicentric study in consecutive cancer patients with newly diagnosed of thromboembolic event (TEE). Eligibility criteria include being > 18 years with a histologically confirmed diagnosis of cancer and a symptomatic or incidental TEE confirmed with an imaging technique in the previous month or any time after the cancer diagnosis and signing of informed consent. The study consists of two types of integrated but independent prospective registries. Regular CAT sub-registry includes information on patient's cancer´s characteristics, anticoagulant treatment provided and outcome data. Special CAT sub-registry includes variables related to special situations of CAT that comprise patients with severe kidney failure, thrombocytopenia, high risk of bleeding related to the cancer or with coexistence of bleeding and patients who receive new treatments such a targeted therapy, antiangiogenics agents and immunotherapy. The registry considers the status of the cancer and the time to assess how the prognosis is changed based on when the thrombus occurs. Some outcomes such as rethrombosis, major bleeding, tumor progression and survival will be valued in various time intervals including 1, 3, 6 and 12 months after the even in the first year; and then every 6 months until the patient's death. RESULTS: After 18 months and with 35 centers and researchers, the registry has 1128 patients. CONCLUSION: TESEO registry will provide clinical real-world evidence for prevention, treatment and complications of CAT in different scenarios that are under-represented in randomized clinical trials.

Supportive consensus.

The paper is concerned with the consensus problem in a multi-agent system such that each agent has boundary constraints. Classical Olfati-Saber's consensus algorithm converges to the same value of the consensus variable, and all the agents reach the same value. These algorithms find an equality solution. However, what happens when this equality solution is out of the range of some of the agents? In this case, this solution is not adequate for the proposed problem. In this paper, we propose a new kind of algorithms called supportive consensus where some agents of the network can compensate for the lack of capacity of other agents to reach the average value, and so obtain an acceptable solution for the proposed problem. Supportive consensus finds an equity solution. In the rest of the paper, we define the supportive consensus, analyze and demonstrate the network's capacity to compensate out of boundaries agents, propose different supportive consensus algorithms, and finally, provide some simulations to show the performance of the proposed algorithms.

Bilateral non-simultaneous optic neuropathy and unilateral macular edema in a patient with POEMS syndrome.

PURPOSE: To report a case of bilateral non-simultaneous optic neuropathy and unilateral macular edema in a patient with polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy, and skin changes (POEMS) syndrome. METHODS: A 61-year-old man with POEMS syndrome had bilateral anterior optic neuropathy and unilateral macular edema. RESULTS: Visual field testing showed bilateral superior altitudinal field defect. Fluorescein angiography revealed unilateral pooling of fluid consistent with cystoid macular edema. Optical coherence tomography (OCT) showed bilateral loss of retinal nerve fiber layer thickness. The erythrocyte sedimentation rate and C-reactive protein values were normal. The serum vascular growth factor measurement was elevated. CONCLUSIONS: This is the first reported case of ophthalmoscopic, angiographic, and OCT evidence of non-simultaneous optic neuropathy and macular edema in this syndrome. The increased vascular permeability could explain all these factors.

[Primary bilateral lipid keratopathy]. / Queratopatía lipoidea primaria bilateral.

CASE REPORT: Observational, case report study. A 45-year-old woman complained of bilateral irritation and photophobia since childhood. Slit-lamp examination revealed yellow-whitish deposits involving the deep stroma of the peripheral half of the cornea in both eyes. The evolution was slowly progressive with a moderate impairment of her visual acuity. DISCUSSION: Lipid deposits adopt symmetric and bilateral configurations; the absence of corneal vascularization and ocular pathology as well as any lipoprotein disorder support the diagnosis of primary lipid keratopathy. The slow progressing disease is also confirmed.

Choroidal neovascularisation associated with optic nerve head drusen: Case report and review of literature. / Neovascularización coroidea asociada a drusas del nervio óptico: caso clínico y revisión de la literatura.

A 21-year-old man was seen for follow-up of optic nerve head drusen (ONHD) in the ophthalmology department. Funduscopy revealed the presence of choroidal neovascularisation (CNV) in the papillomacular bundle of his right eye (RE). The patient was successfully treated with two intravitreal injections of anti-vascular endothelial growth factor (anti-VEGF). Peri-papillary choroidal neovascularisation in papillomacular bundle is a rare complication in patients with ONHD. These forms of CNV show a good response to anti-VEGF treatment.

Which are the colors of the dress? Review of an atypical optic illusion. / ¿De qué colores es el vestido? Revisión de una ilusión óptica atípica.

OBJECTIVE: In 2015 the picture of a dress went viral on social media. A significant proportion of the population saw it as golden and white (G&W), while another significant proportion saw it as blue and black (B&B). The aim of this article is to review the related literature. MATERIAL AND METHODS: Bibliographic search conducted in Pubmed and Google. The algorithm used was: (color OR colour) AND (dress OR #thedress). The search was limited to the years 2015-2017. No language restrictions were used. The references of the located articles were used to widen the search. RESULTS: The search algorithm retrieved 23 articles related to the topic. Most of the works have been published in journals in the field of perception. Most works address the topic from the point of view of chromatic constancy. Genetic factors seem to have a low weight in the way the dress is perceived. There are few studies on the potential influence of ocular factors. CONCLUSION: This illusion has gained little attention in ophthalmology journals. Although colour constancy is certainly involved, there is still no theory available to explain the dichotomous character of this optical illusion.

General recommendations paper on the management of older patients with cancer: the SEOM geriatric oncology task force's position statement.

Population aging is associated with greater numbers of older people with cancer. Thanks to treatment advances, not only are more seniors diagnosed with cancer, but there are also more and more older cancer survivors. This upward trend will continue. Given the heterogeneity of aging, managing older patients with cancer poses a significant challenge for Medical Oncology. In Spain, a Geriatric Oncology Task Force has been set up within the framework of the Spanish Society for Medical Oncology (SEOM). With the aim of generating evidence and raising awareness, as well as helping medical oncologists in their training with respect to seniors with cancer, we have put together a series of basic management recommendations for this population. Many of the patients who are assessed in routine clinical practice in Oncology are older. CGA is the basic tool by means of which to evaluate older people with cancer and to understand their needs. Training and the correct use of recommendations regarding treatment for comorbidities and geriatric syndromes, support care, and drug-drug interactions and toxicities, including those of antineoplastic agents, as detailed in this article, will ensure that this population is properly managed.

[Eclipse retinopathy: three case reports]. / Retinopatía por eclipse. A propósito de tres casos.

CASE REPORT: We present the evolution of eclipse retinopathy in 3 patients who came to our hospital after the eclipse of October 2005 and had foveal lesions and visual field alterations. DISCUSSION: Eclipse retinopathy is a maculopathy that occurs after exposure to intense solar radiation, such as occurs during an eclipse, and is produced by a photochemical mechanism. Although the macular changes and symptoms are usually reversible, residual defects at the level of the EPR and scotoma in visual fields can occur. For these reasons the most appropriate treatment is prevention by means of public awareness campaigns.

Safety and efficacy of primary thromboprophylaxis in cancer patients.

Cancer is often complicated by venous thromboembolism (VTE), a common and potentially fatal complication associated with poor prognosis in these patients. An increased incidence of VTE is being observed due to the advanced age of cancer patients, the thrombogenic effect of novel drugs and advances in the diagnosis of related complications. In this review, we look at five different risk groups of cancer patients with an increased probability of developing VTE, including hospitalized patients undergoing chemotherapy, patients undergoing a surgical procedure, ambulatory patients undergoing chemotherapy, patients with a central venous access and patients receiving antiangiogenic drugs or anticoagulant therapy due to previous chronic diseases. The aim of this review is to summarize the most important clinical evidence reported to date on the suitability of primary thromboprophylaxis to cancer patients. Recommendations have drawn up for each group based on current evidence and guidelines to facilitate decision-making in clinical practice.

Traumatic cyclodialysis treated with transscleral ciclodiode laser: Anterior and posterior segment evolution. / Ciclodiálisis traumática tratada con láser ciclodiodo transescleral: evolución de la exploración del segmento anterior y posterior.

CASE REPORT: A 35-year-old man suffered a severe hipotension maculopathy after being kicked in his left eye. He presented a broad area of iridodialisis. Gonioscopy, ultrasound biomicroscopy and optic coherence tomography were not able to locate the suspected cyclodialysis. Medical treatment was ineffective. Five months later the patient received transcleral diode laser cyclophotocoagulation with clinical resolution. DISCUSSION: Transscleral diode laser constitutes an effective treatment, with low iatrogenia, that can solve cases of ocular hypotension, even when the location of the cyclodialysis has not been determined.

Significant decline in lymphatic filariasis associated with nationwide scale-up of insecticide-treated nets in Zambia.

Lymphatic filariasis (LF) is a mosquito-borne disease, broadly endemic in Zambia, and is targeted for elimination by mass drug administration (MDA) of albendazole and diethylcarbamazine citrate (DEC) to at-risk populations. Anopheline mosquitoes are primary vectors of LF in Africa, and it is possible that the significant scale-up of malaria vector control over the past decade may have also impacted LF transmission, and contributed to a decrease in prevalence in Zambia. We therefore aimed to examine the putative association between decreasing LF prevalence and increasing coverage of insecticide-treated mosquito nets (ITNs) for malaria vector control, by comparing LF mapping data collected between 2003-2005 and 2009-2011 to LF sentinel site prevalence data collected between 2012 and 2014, before any anti-LF MDA was started. The coverage of ITNs for malaria was quantified and compared for each site in relation to the dynamics of LF. We found a significant decrease in LF prevalence from the years 2003-2005 (11.5% CI95 6.6; 16.4) to 2012-2014 (0.6% CI95 0.03; 1.1); at the same time, there was a significant scale-up of ITNs across the country from 0.2% (CI95 0.0; 0.3) to 76.1% (CI95 71.4; 80.7) respectively. The creation and comparison of two linear models demonstrated that the geographical and temporal variation in ITN coverage was a better predictor of LF prevalence than year alone. Whilst a causal relationship between LF prevalence and ITN coverage cannot be proved, we propose that the scale-up of ITNs has helped to control Anopheles mosquito populations, which have in turn impacted on LF transmission significantly before the scale-up of MDA. This putative synergy with vector control has helped to put Zambia on track to meet national and global goals of LF elimination by 2020.

Characterisation of fluoroquinolone-resistant clinical isolates of Streptococcus pyogenes in Barcelona, Spain.

Resistance mechanisms and clonal relationships were determined for six Streptococcus pyogenes isolates with low- or high-level ciprofloxacin resistance. Four isolates displayed reduced susceptibility to ciprofloxacin and levofloxacin and had alterations in ParC: Ser80-->Pro (isolate emm3.1); Ser79-->Ala (two isolates emm6.0); and a double substitution Ser79-->Phe and Ala121-->Val (isolate emm12.27). Two isolates (emm12.26) displayed high-level resistance to ciprofloxacin and levofloxacin, as well as to other quinolones. These isolates had the same double substitution in ParC as isolate emm12.27, and an additional substitution (Ser81-->Tyr) in GyrA. Resistance patterns, emm typing and sequencing of the quinolone resistance-determining regions defined two clusters containing three and two isolates, respectively.
