Clinical and Sonographic Classification of Neurofibromas in Children with Neurofibromatosis Type 1 - A Cluster Analysis.

PURPOSE: High-frequency ultrasound allows the accurate identification of neurofibromas in neurofibromatosis type 1 (NF1). This study aimed to analyze the ultrasound features of neurofibromas in children with NF1, to establish a classification based on the clinical and sonographic patterns of the different types of neurofibromas, and to evaluate the interobserver correlation coefficient (κ) of this classification. MATERIALS AND METHODS: In this prospective, single referral center observational study, clinical and ultrasound findings of neurofibromas in children diagnosed with NF 1 were analyzed. To identify the ultrasound patterns, a cluster analysis allowing the inclusion of both clinical and ultrasound data was designed. The κ coefficient was calculated using 9 external evaluators. RESULTS: 265 ultrasound scans were performed on a total of 242 neurofibromas from 108 children diagnosed with NF1. Cluster analysis allowed the identification of 9 patterns (Snedecor's F, P < 0.001) classified as "classic" cutaneous neurofibroma, blue-red neurofibroma, pseudoatrophic neurofibroma, nodular subcutaneous neurofibroma, diffuse subcutaneous neurofibroma, congenital cutaneous neurofibroma, congenital plexiform neurofibroma, congenital diffuse and plexiform neurofibroma, and subfascial neurofibroma. The κ coefficient of the interobserver ratings was 0.82. CONCLUSION: Patterns identified in the cluster analysis allow neurofibromas to be classified with a very high interobserver correlation.

Extra-criteria antiphospholipid antibodies in patients with small vessel brain lesions and clinical manifestations associated with antiphospholipid syndrome.

OBJECTIVES: Neurological manifestations compatible with small vessel brain lesions (SVBL), such as migraine, cognitive impairment, seizures, and transverse myelitis, may be related to antiphospholipid syndrome (APS) and patients could need APS therapies even though they do not fit into thrombosis or obstetric morbidity. Furthermore, extra-criteria antiphospholipid antibodies (aPL) provide an increase in sensitivity in patients with clinical manifestations related to APS but negative for IgG/IgM anticardiolipin (aCL), anti-ß2 glycoprotein I (aß2GPI), and lupus anticoagulant, which are the antibodies included in the classification criteria for APS. METHODS: We determined extra-criteria aPL in 65 SVBL patients with neurological traits and Magnetic Resonance Imaging suggestive of APS but negative for APS classification criteria, 47 of whom were prospectively followed and tested over three years. A group of 95 patients with autoimmune diseases (AD) but without clinical traits of APS was also studied. RESULTS: A persistent presence of extra-criteria aPL was detected in 27.7% of patients: 12.77% IgM anti- prothrombin (PT), 6.38% IgG anti-PT, 6.38% IgM anti-phosphatidylethanolamine (PE), 4.26% IgA aß2GPI, 2.13% IgG anti-phosphatidylserine/prothrombin (PS/PT) and 2.13% IgM anti-PS/PT. There was a tendency towards a higher prevalence of these aPL in SVBL patients than in AD - especially for IgA aß2GPI - and a lack of IgG aPS/PT positivity in the AD group. We found no SVBL patient positive for IgA aCL, IgG anti-PE, annexin V, or aß2GPI domain I. CONCLUSIONS: Extra-criteria aPL can improve sensitivity for APS diagnosis in patients with SVBL, especially IgA aß2GPI and IgG anti-PS/PT antibodies.

Extracorporeal photopheresis in paediatric patients: A retrospective comparison between different 'off-line' protocols.

BACKGROUND AND OBJECTIVES: Extracorporeal photopheresis (ECP) has been shown to be an effective treatment for graft-versus-host disease (GvHD). However, information regarding lymphocyte collection for ECP in children is limited. The aim of this study was to analyse and compare lymphocyte collection for ECP in children using different devices and protocols. Moreover, we have studied both safety and variables of the infused product related to treatment efficacy. PATIENTS AND METHODS: This was a retrospective study of 91 patients who underwent 1524 apheresis procedures with either the COBE Spectra or Spectra Optia system. The comparison study between the Optia protocols (MNC and CMNC) was prioritized. We analysed 578 procedures using the Optia blood cell separator: 204 and 374 using the MNC and the CMNC protocol, respectively. RESULTS: The Optia CMNC protocol showed better collection efficiency, with increased lymphocyte collection per kg of body weight (p < 0.001). On multivariate analysis, the type of protocol showed no relationship with haematocrit or platelet loss. Most procedures were well-tolerated, with the most frequent adverse events related to venous access (21.7%). Seventy-one percent of patients had either partial or complete clinical GvHD response. In the multivariate model, only two variables were associated with a better response to ECP, younger age and a greater increase of B lymphocytes after treatment. CONCLUSION: Lymphocyte collection for ECP is well-tolerated in most children, achieving complete or partial response in more than half of GvHD patients. CMNC is the optimal software to perform lymphocyte collection in children.

Triflusal in Patients with Acute Coronary Syndrome and Acetylsalicylic Acid Hypersensitivity.

BACKGROUND: Acetylsalicylic acid hypersensitivity (ASAH) limits therapeutic options in patients with acute coronary syndrome (ACS), who benefit from dual antiplatelet therapy (DAPT), especially when undergoing stent implantation. Our aim was to evaluate the safety and efficacy of triflusal in patients with ACS and ASAH. METHODS AND RESULTS: Two-center retrospective study of patients diagnosed with ACS and ASAH from January 1, 2000, to May 1, 2020. Sixty-six patients were treated with triflusal. ASAH was confirmed with tests in 15 patients (22.7%). Forty-nine patients (74.2%) presented history of other drug allergies. Fifty-nine patients (89.4%) underwent stent implantation. DAPT was prescribed for ≥12 months in 54 patients. No adverse reactions to triflusal were reported. During a median follow-up of 5.12 years [IQR 2.7-9.9], rate of cardiovascular (CV) mortality was 6.1%, nonfatal myocardial infarction 12.1%, and ischemic stroke 4.5%. No cases of definite stent thrombosis occurred. Bleeding Academic Research Consortium grade ≥2 was observed in 3 patients during follow-up. CONCLUSION: In this series of patients presenting with ACS and ASA hypersensitivity, triflusal showed good tolerability and was associated with a low rate of CV and bleeding events.

Cognitive and behavioral profiles of pediatric surgical candidates with frontal and temporal lobe epilepsy.

BACKGROUND: We aimed to prospectively analyze memory and executive and social cognitive functioning in patients with drug-resistant frontal lobe epilepsy (FLE) and temporal lobe epilepsy (TLE) with focal lesions and isolate the impact of intellectual ability on specific deficits. METHODS: A neuropsychological evaluation was performed in 23 children with FLE, 22 children with TLE, and 36 healthy pediatric controls (HCs). Patients in the epilepsy groups had a range of lesions, including low-grade epilepsy-associated tumors (LEAT), focal cortical dysplasia (FCD) type II, and mesial temporal sclerosis (MS). RESULTS: There were no significant differences between children with FLE and TLE regarding memory, executive, or social cognitive functioning. General Ability Index (GAI) was a predictor of memory, executive function, and social cognition scores and was influenced by age at onset, duration of epilepsy, and number of antiepileptic drugs (AEDs) prescribed at the time of assessment. Working Memory Index scores of patients with TLE, which measure verbal mnesic processing, were significantly lower than those of HCs and patients with TLE. The greatest differences in both clinical groups compared to HCs were recorded in cognitive executive functions, and patients with FLE had lower scores in this domain. Regarding behavioral executive functions, patients with TLE presented impaired emotional control and impulse inhibition and patients with FLE exhibited decreased flexibility. CONCLUSION: Consistent with previous research, our findings provide further detailed evidence of small differences in cognitive performance among children with FLE and TLE. These differences emerge on analysis of the factors with which deficits are associated.

[Long-term effect analysis of a cognitive stimulation program in mild cognitive impairment elderly in Primary Care: A randomized controlled trial]. / Análisis del efecto a largo plazo de un programa de estimulación cognitiva en mayores con deterioro cognitivo leve en Atención Primaria: ensayo controlado aleatorizado.

OBJECTIVE: To provide evidence about the efficacy of a community health intervention through a cognitive stimulation program at long term in older people with mild cognitive impairment. DESIGN: Randomized controlled trial (CONSORT group norms). LOCATION: San José Norte-Centro Primary Care Center and La Caridad Foundation (Zaragoza, Spain). PARTICIPANTS: Twenty-nine people over 65 years old with a 24-27 MEC score that completed 48 months follow up. They were randomized between the intervention group (15) and the control group (14). INTERVENTIONS: The intervention was applied in 10 sessions of 45min for 10 weeks using the red notebook tool for mental activation that works memory, orientation, language, praxis, gnosis, calculation, perception, logical reasoning, attention and executive functions. MAIN MEASUREMENTS: The main outcome variables were MEC-35, Set-test, Barthel index, Lawton-Brody scale, Goldberg anxiety scale and Yesavage geriatric depression scale short form. RESULTS: Increases of the main result variable over the baseline level of MEC-35 were analyzed. On average, the intervention group obtained higher scores than control: 3.14 points post intervention, 3.76 points after 6 months and 2.26 points more than control group after 12 months. All the differences were statistically significant. After 48 months the intervention group obtained 2 points more than control group. The intervention did not improve verbal fluency, activity daily living and mood. CONCLUSIONS: Our cognitive stimulation program seems to improve cognitive performance, measured with the variable MEC-35 at post intervention, 6, 12 and 48 months. There is no evidence of improvement in verbal fluency, activity daily livings and mood. Clinicaltrials.gov Identifier: NCT03831061.

Reducing overtreatment associated with overdiagnosis in cervical cancer screening-A model-based benefit-harm analysis for Austria.

A general concern exists that cervical cancer screening using human papillomavirus (HPV) testing may lead to considerable overtreatment. We evaluated the trade-off between benefits and overtreatment among different screening strategies differing by primary tests (cytology, p16/Ki-67, HPV alone or in combinations), interval, age and diagnostic follow-up algorithms. A Markov state-transition model calibrated to the Austrian epidemiological context was used to predict cervical cancer cases, deaths, overtreatments and incremental harm-benefit ratios (IHBR) for each strategy. When considering the same screening interval, HPV-based screening strategies were more effective compared to cytology or p16/Ki-67 testing (e.g., relative reduction in cervical cancer with biennial screening: 67.7% for HPV + Pap cotesting, 57.3% for cytology and 65.5% for p16/Ki-67), but were associated with increased overtreatment (e.g., 19.8% more conizations with biennial HPV + Papcotesting vs. biennial cytology). The IHBRs measured in unnecessary conizations per additional prevented cancer-related death were 31 (quinquennial Pap + p16/Ki-67-triage), 49 (triennial Pap + p16/Ki-67-triage), 58 (triennial HPV + Pap cotesting), 66 (biennial HPV + Pap cotesting), 189 (annual Pap + p16/Ki-67-triage) and 401 (annual p16/Ki-67 testing alone). The IHBRs increased significantly with increasing screening adherence rates and slightly with lower age at screening initiation, with a reduction in HPV incidence or with lower Pap-test sensitivity. Depending on the accepted IHBR threshold, biennial or triennial HPV-based screening in women as of age 30 and biennial cytology in younger women may be considered in opportunistic screening settings with low or moderate adherence such as in Austria. In organized settings with high screening adherence and in postvaccination settings with lower HPV prevalence, the interval may be prolonged.

The Impact of the Change in Payment System for German Psychiatric Clinics on Treatment Success: An Interrupted Time Series Analysis.

BACKGROUND: In Germany a new reimbursement system for psychiatric clinics was proposed in 2009 based on the § 17d KHG Psych-Entgeltsystem. The system can be voluntary implemented by clinics since 2013 but therapists are frequently afraid it might affect treatment negatively. OBJECTIVES: To evaluate whether the new system has a negative impact on treatment success by analysing routinely collected data in a Bavarian clinic. MATERIAL AND METHODS: Aggregated data of 1760 patients treated in the years 2007-2016 was analysed with segmented regression analysis of interrupted time series to assess the effects of the system on treatment success, operationalized with three outcome variables. A negative change in level after a lag period was hypothesized. The robustness of results was tested by sensitivity analyses. RESULTS: The percentage of patients with treatment success tends to increase after the new system but no significant change in level was observed. The sensitivity analyses corroborate results for 2 outcomes but when the intervention point was shifted, the positive change in level for the third outcome became significant. CONCLUSIONS: Our initial hypothesis is not supported. However, the sensitivity analyses disclosed uncertainties and our study has limitations, such as a short observation time post intervention. Results are not generalizable as data of a single clinic was analysed. Nevertheless, we show the importance of collecting and analysing routine data to assess the impact of policy changes on patient outcomes.

Frequency and Reasons of Dual Antiplatelet Therapy Discontinuation and Switching of P2Y12 Inhibitors in Patients with Acute Coronary Syndrome Treated with Stent Implantation.

BACKGROUND: Incidence and reasons of dual antiplatelet therapy (DAPT) discontinuation and switching between P2Y12 inhibitors in acute coronary syndrome (ACS) patients treated with a stent have been poorly studied. METHODS AND RESULTS: In a prospective single-center study, 283 consecutive patients presenting with ACS were treated with stent implantation between July 2015 and January 2016. Follow-up was achieved at 12 months in 273 patients using the electronic patient file and telephone interview. Switching from clopidogrel to a new antiplatelet agent (ticagrelor or prasugrel) or vice versa occurred in 60 (21.2%) patients. The most frequent reasons for switching were medical decisions not associated with bleeding events and concomitant use of chronic oral anticoagulation. Among the patients with a 1-year follow-up, 42 (15.4%) prematurely discontinued DAPT; 25 of them did so due to the need for an invasive procedure. DAPT premature discontinuation was not significantly associated with an increased 1-year risk of cardiovascular death or serious cardiac ischemic events (HR 2.08 [CI 95%: 0.88-4.94, p = 0.099]). CONCLUSIONS: DAPT discontinuation and switching between P2Y12 inhibitors are not uncommon in patients with ACS treated with a stent. The most frequent reasons were the need for an invasive procedure and medical decisions.

Randomized clinical trial evaluating the effect of a visual educational leaflet on the preparation of colonoscopies in hospitalized patients.

BACKGROUND: the safety and diagnostic accuracy of colonoscopies depends on the quality of colon cleansing. Several factors have been reported that affect the quality of bowel cleansing, hospitalization being one of them. AIMS: the aim of the study was to investigate whether a visual educational leaflet improved the level of cleanliness achieved in hospitalized patients undergoing a colonoscopy and to identify predictors of a poor bowel preparation. METHODS: a prospective, single-center, endoscopist-blinded, randomized controlled trial was performed. The intervention group was given a visual educational leaflet and both groups received four liters of polyethylene glycol solution. Demographic data, personal history, reason for admission and indication for colonoscopy, work shift during which the procedure was performed and endoscopy findings were collected. The Boston Bowel Preparation Scale (BBPS) was used to assess the bowel preparation. RESULTS: one hundred and thirty-six patients were included in the study; 51.5% were male, with a mean age of 64.3 ± 17.6 years. The educational leaflet did not result in a difference in the total BBPS obtained between the standard group and the intervention group (7 [6-9] vs 6 [5.7-9]; p = 0.17). According to the multivariable analysis, the only factors associated with a poor bowel cleansing were heart disease (OR 3.37 [1.34-8.46]; p = 0.010) and colorectal cancer (OR 3.82 [1.26-11.61]; p = 0.018). CONCLUSION: the use of a visual educational leaflet for the preparation of colonoscopies did not provide a significant improvement in hospitalized patients in our health area. Heart disease was identified as the only predictor of poor preparation for colonoscopy.

Movement artifacts in pediatric cutaneous ultrasonography.

BACKGROUND: Cutaneous ultrasonography can be challenging in children. We aim to identify the most complicated cases and the best timing for assessment. METHODS: We retrospectively reviewed sonographic exams in pediatric patients from our cutaneous ultrasonography clinic over a two-year period. Movement artifacts were classified according to their consequences and their frequency was studied in relation to the age of the patient, location of the lesion, and underlying pathology. RESULTS: The overall frequency of exams affected by movement artifacts was 16.76% (91/543) and all belonged to children younger than 4 years of age. The frequency of impaired sonographies was particularly low in patients aged 0 to 4 months (12.77%; 6/47) and particularly high in children aged from 4 to 12 months (56.60%; 60/106). Regarding location, exams were more frequently disadvantaged when assessing the head and neck area (44.53%; 61/137). In relation to pathology, developmental anomalies showed a significantly higher frequency of exams damaged by movement artifacts (41.82%; 23/55). CONCLUSIONS: Cutaneous ultrasonography without sedation can be particularly difficult in children aged between 4 and 12 months, especially when lesions are located on the head and neck and a Doppler exam is required. When assessing congenital lesions, the first four months of life are ideal for a first examination.

Macrolide use in the previous years is associated with failure to eradicate Helicobacter pylori with clarithromycin-containing regimens.

BACKGROUND: There is some evidence that prior use of macrolide antibiotics is a useful predictor of the likelihood of standard triple therapy failure in Helicobacter pylori eradication. In this study, we have evaluated whether previous intake of macrolides correlates with failure to eradicate H. pylori using two different first-line clarithromycin-containing regimens. MATERIALS AND METHODS: Retrospective study of 212 patients with H. pylori infection treated with one of two first-line clarithromycin-containing regimens: 108 patients treated with triple therapy for 10 days and 104 patients treated with concomitant therapy for 10 days. The intake of macrolides (clarithromycin, azithromycin, and other macrolides) prior to the eradication therapy was obtained from the electronic medical record, which contains information regarding all the medication prescribed to the patients since the year 2004. RESULTS: One hundred of 212 patients (47.2%) had received at least one treatment with macrolides during the years prior to the eradication therapy. H. pylori eradication rates were significantly lower in patients with previous use compared to patients without previous use of macrolides, both with triple therapy (60.8% vs 92.9%; P < .0001) and with concomitant therapy (85.7% vs 98.2%; P = .024). CONCLUSIONS: Previous use of macrolides correlates with a low H. pylori eradication rate with triple and concomitant clarithromycin-containing regimens. In addition, our study shows that in patients without previous use of macrolides, triple therapy achieves per-protocol eradication rates over 90%.

Hepatitis B virus e antigen-negative chronic infection. Treatment based on glutamic pyruvic transaminase and hepatitis B virus deoxyribonucleic acid cut-off values. / Infección crónica por virus de la hepatitis B antígeno e negativo. Manejo en función de puntos de corte de glutámico-pirúvica transaminasa y ácido desoxirribonucleico del virus de la hepatitis B.

OBJECTIVES: To identify glutamic pyruvic transaminase (GPT) and hepatitis B virus DNA (HBV-DNA) cut-off values at diagnosis in patients with hepatitis B virus e antigen-negative chronic infection (HBeAg(-)), which may be predictors of clinical course, prognosis and/or the need for antiviral therapy. METHODS: A retrospective and observational cohort study of patients diagnosed with HBeAg(-) chronic infection (2005-2012). A normal GPT cut-off value at diagnosis that predicts abnormal GPT values in the clinical course of the infection, a baseline HBV-DNA cut-off value that predicts an increase in HBV-DNA above 2,000IU/ml, and GPT and HBV-DNA as predictors of the need for treatment were investigated using ROC curves. RESULTS: 126 patients were enrolled (follow-up: 42.1±21.5months), 93 of which had normal GPT levels at diagnosis. In the ROC curve analysis, 900IU/ml was found to be the HBV-DNA cut-off value that best predicted this value's increase above 2,000IU/ml (sensitivity: 90%; specificity: 88%; PPV: 79%; NPV: 100%; diagnostic precision: 89%), while 25mU/ml was the normal GPT cut-off value at diagnosis that best predicted subsequently elevated GPT levels (sensitivity: 95.4%; specificity: 81.6%; PPV: 67%; NPV: 96%; diagnostic precision: 80.6%). Patients with GPT 26-40mU/ml at diagnosis presented with more complications or required more treatment than subjects with GPT≤25mU/ml (P<.05). The combined GPT and HBV-DNA values that elicited the highest treatment need were 38mU/ml of GPT and 6,000IU/ml of HBV-DNA (sensitivity: 75%; specificity: 93.4%; PPV: 60%; NPV: 96.6%). CONCLUSION: HBeAg(-) patients with GPT<25mU/ml and HBV-DNA<900IU/ml at diagnosis have positive outcomes and may not require such stringent follow-up in the first years after diagnosis.

Characteristics and course of chronic hepatitis B e antigen-negative infection. / Características y evolución de la infección crónica por virus de la hepatitis B antígeno e negativo.

OBJECTIVE: To describe the epidemiological, analytical and histological characteristics and clinical course of hepatitis B virus (HBV) carriers with negative HBe antigen. MATERIAL AND METHODS: Observational, retrospective cohort study of HBV carriers with negative HBe antigen (2005-2012), with no other causes of liver disease. RESULTS: One hundred and thirty-eight patients were included, with mean age 40.5±12.2 years; 54% were women, and 38% were of foreign origin; the number of foreign patients significantly increased (P<.001) over the years. Transaminases were normal in nearly 75% and HBV-DNA was <2,000IU/ml in 56% of patients at diagnosis. There was a gradual decrease in HBV-DNA levels in inactive carriers over the study period. Fibrosis study was performed in 47% of patients by Fibroscan® or liver biopsy: 55.4% normal histology and 6.1% cirrhosis. Just over three quarters of patients (77.77%) were inactive carriers. Treatment was required in 15.5% of patients (20% because of cirrhosis and 80% HBeAg-negative chronic hepatitis B). Five patients cleared HBsAg (annual rate .94%), all of whom presented HBV-DNA <2,000IU/ml at diagnosis. Five patients developed complications (3.6%), 4 of them hepatocellular carcinoma (HCC), of which only 2 had cirrhosis. There was 1 HBV-related death (.72%). CONCLUSION: Among HBV carriers with negative HBe antigen, inactive HBs-Ag carriers are predominant. HBV-DNA gradually decreases in the first few years after diagnosis. Morbidity and mortality are low, especially if glutamic pyruvic transaminase (GPT) is normal and HBV-DNA levels are low at diagnosis. Treatment is needed in a considerable number of patients. HCC is the most frequent complication, even in the absence of cirrhosis.

Outcomes and Complications of Tibial Tubercle Fractures in Pediatric Patients: A Systematic Review of the Literature.

BACKGROUND: Systematic review of the literature was done to determine (1) the frequency and type of associated injuries, (2) frequency of concomitant Osgood-Schlatter disease, (3) methods of treatment, (4) functional and radiologic outcomes according to fracture type, and (5) complications of tibial tubercle fractures in pediatric patients. METHODS: A systematic review of the English literature from 1970 to 2013 included 23 eligible articles reporting 336 fractures with a mean follow-up of 33.56 months (range, 5.7 to 115 mo). Fractures were classified by a comprehensive system that included characteristics of previous systems. Clinical outcomes were assessed by a qualitative scale (excellent/fair/poor), the rate of return to preinjury activity, and knee range of motion. Rate of fracture healing, associated injuries (patellar/quadriceps tendon avulsion and meniscal tears), compartment syndrome, and complications were also recorded. RESULTS: Mean age at surgery was 14.6 years and the most common fracture reported was type III (50.6%). The overall associated injury rate was 4.1%, most common in type III fractures (4.7%). Compartment syndrome was present in 3.57% of cases. Open reduction and internal fixation were done in 98% of surgical cases. Rates of return to preinjury activity and knee range of motion were 98%, regardless of the type of fracture. Fracture consolidation was achieved in 99.4% of cases. Overall complication rate was 28.3%; removal of an implant because of bursitis (55.8%) was most common. Tenderness/prominence (17.9%) and refracture (6.3%) were also common. CONCLUSIONS: Treatment of tibial tubercle fractures in adolescents produced good clinical and radiologic results regardless of fracture type, which was more related to potential complications. Fractures with intra-articular involvement tended to present with more associated injuries and to have fair functional outcomes, suggesting that advanced imaging may be justified with these fractures. Complications could be more common than expected without a significant effect on final outcome. Finally, there is a need for longer follow-up to determine long-term outcomes. LEVEL OF EVIDENCE: Level III-systematic review of level III/IV studies.

Nail involvement can predict enthesopathy in patients with psoriasis.

BACKGROUND: Although subclinical enthesopathy is a well-established diagnostic criterion for psoriatic arthritis (PsA), it is frequently overlooked, as many patients are asymptomatic. The possibility of finding a clinical clue predicting enthesopathy would help clinicians establish an early diagnosis of PsA. MATERIAL AND METHODS: A prospective single-center study of a total of 90 patients with psoriasis was conducted to assess the presence of entheseal abnormalities as detected by ultrasound, and to determine any correlation with nail involvement. RESULTS: Entheseal abnormalities were found in 23 patients (25.5 %), 19 (82.6 %) of whom showed nail involvement, whereas four (17.4 %) individuals did not. Enthesopathy was present in 31.1 % (19/61) of patients with onychopathy compared to 13.8 % (4/29) of those without nail involvement (p  =  0.07). There was a significant correlation between target NAPSI score and evidence of enthesopathy. In addition, the number of nails affected also showed a significant correlation with the presence of enthesopathy (p  = 0.035). CONCLUSIONS: Clinical evidence of onychopathy may be the clue to an early diagnosis of enthesopathy in psoriasis patients.

Nagelbefall kann bei Patienten mit Psoriasis auf eine Enthesiopathie hinweisen.

HINTERGRUND: Obwohl subklinische Enthesiopathie ein gut etabliertes diagnostisches Merkmal der Psoriasisarthritis (PsA) ist, wird sie häufig übersehen, da viele Patienten asymptomatisch sind. Gäbe es klinische Hinweise auf das Vorliegen einer Enthesiopathie, würde dies den Klinikern die Möglichkeit eröffnen, eine PsA frühzeitig zu diagnostizieren. MATERIAL UND METHODEN: Es wurde eine monozentrische prospektive Studie mit insgesamt 90 Psoriasis-Patienten durchgeführt, um mittels Ultraschall das Vorliegen von Enthesenanomalien zu untersuchen und eine Korrelation mit dem Befall der Nägel festzustellen. ERGEBNISSE: Enthesenanomalien wurden bei 23 Patienten (25,5 %) gefunden, von denen 19 (82,6 %) Nagelbefall aufwiesen. Bei 4 Patienten waren die Nägel nicht betroffen. Enthesiopathie lag bei 31,1 % (19/61) der Patienten mit Onychopathie vor, von den Patienten ohne Nagelbefall litten nur 13,8 % (4/29) an Enthesiopathie (p = 0,07). Zwischen dem Target-NAPSI-Score und dem Vorliegen einer Enthesiopathie bestand eine signifikante Korrelation. Eine signifikante Korrelation bestand darüber hinaus auch zwischen dem Vorliegen einer Enthesiopathie und der Anzahl der betroffenen Nägel (p = 0,035). SCHLUSSFOLGERUNGEN: Klinische Belege für eine Onychopathie können der Schlüssel für die frühe Diagnose einer Enthesiopathie bei Psoriasis-Patienten sein.

Primary prevention of anxiety disorders in primary care: A systematic review.

OBJECTIVE: Anxiety disorders are the most prevalent psychiatric disorders in primary care and have significant social, economic, and interpersonal costs. Primary care is an ideal setting to prevent the appearance of anxiety disorders. The aim of this study was to evaluate the efficacy and cost-effectiveness of primary prevention interventions in anxiety disorders in the adult population receiving primary health care. METHODS: A literature search was carried out in four databases-PubMed, PsycInfo, Cochrane, and Web of Science-from January 1980 to November 2013. Clinical trials and systematic reviews published in English and non-English languages and that evaluated the efficacy and/or cost-effectiveness of interventions of primary prevention for anxiety in primary care in the general adult population were included. Risk of bias was assessed by the Cochrane Risk Bias Tool and Overview Quality Assessment Questionnaire. RESULTS: No high-quality research was identified that studied primary prevention of anxiety disorders in the adult population in the primary care setting. The few studies that exist focus on the child-adolescent population or on other types of interventions, usually as secondary prevention. CONCLUSION: This study emphasizes the need for the development of high-quality clinical trials on the prevention of anxiety disorders in primary care.

Detection of adverse events in general surgery using the " Trigger Tool" methodology.

INTRODUCTION: Surgery is one of the high-risk areas for the occurrence of adverse events (AE). The purpose of this study is to know the percentage of hospitalisation-related AE that are detected by the «Global Trigger Tool¼ methodology in surgical patients, their characteristics and the tool validity. MATERIAL AND METHODS: Retrospective, observational study on patients admitted to a general surgery department, who underwent a surgical operation in a third level hospital during the year 2012. The identification of AE was carried out by patient record review using an adaptation of «Global Trigger Tool¼ methodology. Once an AE was identified, a harm category was assigned, including the grade in which the AE could have been avoided and its relation with the surgical procedure. RESULTS: The prevalence of AE was 36,8%. There were 0,5 AE per patient. 56,2% were deemed preventable. 69,3% were directly related to the surgical procedure. The tool had a sensitivity of 86% and a specificity of 93,6%. The positive predictive value was 89% and the negative predictive value 92%. CONCLUSIONS: Prevalence of AE is greater than the estimate of other studies. In most cases the AE detected were related to the surgical procedure and more than half were also preventable. The adapted «Global Trigger Tool¼ methodology has demonstrated to be highly effective and efficient for detecting AE in surgical patients, identifying all the serious AE with few false negative results.

Predictors of adherence to follow-up and treatment success in childhood obesity.

INTRODUCTION: Management of childhood obesity, based upon behavioural, physical activity and dietary guidance, usually achieves limited success and is hindered by a high attrition rate. The identification of potential predictors of either weight loss or early weight management attrition could help develop personalised management plans in order to improve patient outcomes. PATIENTS AND METHODS: We conducted a retrospective study in a cohort of 1300 patients with obesity managed in speciality clinics for up to 5 years with outpatient conservative treatment. We studied the family background and personal characteristics (demographic, behavioural, psychosocial, anthropometric and metabolic) of patients who dropped out before completing the first year of the programme and patients who achieved significant weight loss, with a separate analysis of patients who achieved substantial reductions in weight compared to the rest of the cohort. RESULTS: The mean age of the patients in the cohort was 10.46 years (SD, 3.48) the mean BMI z-score 4.01 (SD, 1.49); 52.8% of the patients were male, 53.3% were prepubertal, 75.8% were Caucasian and 19% Latin. We found a higher proportion of Latinla ethnicity and compulsive eating in the group of patients with early attrition from the weight management follow-up. In the group of patients with substantial weight loss, a greater proportion were male, there was a higher frequency of dietary intake control at home and obesity was more severe, and the latter factor was consistently observed in patients who achieved substantial weight loss at any point of the follow-up. CONCLUSIONS: Some family and personal characteristics in childhood obesity are associated with an increased risk of early withdrawal from follow-up or a greater probability of successful outcomes; however, the predictive value of these variables is limited.
