Abstract
The performance of day-to-day tasks, whether satisfactory or unsatisfactory, varies due to several environmental synchronizers, including the 24-hour light-dark cycle. For instance, human performance on physical and/or cognitive demanding activities reaches its peak during the day when the body temperature is at its circadian peak. Individual differences in the circadian peaks in temperature along with individuals' timing of sleep is referred to as chronotype. Here, we aimed to answer if (a) chronotypes affect the performance of students in a Brazilian full-time school with an early start time and if (b) there are differences in performance based on chronotype. We expected to find (a) a positive effect of the morning chronotype on the students' performance, particularly in subjects that take place in early morning; (b) while a negative effect of the evening chronotype in that same period. To address the effect of the chronotype on the students' scholar performance we build a Generalized Linear Mixed Model (GLMM). Results support the hypothesis that the students' performance is partially attributed to their chronotype. In particular, our findings shows that evening-type students are expected to have an increase of 0.038 (p ≤0.05) log counts on their performance in Portuguese classes compared to other chronotypes. Here we add evidence for the effect that individual chronotypes have on the students' performance in a Brazilian full-time middle school. Distinctive features of the studied Brazilian full-time middle school related to chronotypes are discussed.

Abstract
Previous studies using ileostomy samples from study participants demonstrated that the spore-forming probiotic Bacillus subtilis DE111® can germinate in the small intestine as early as 4 hours after ingestion. Metabolomics, proteomics and sequencing technologies, enabled further analysis of these samples for the presence of hypoglycaemic, hypolipidemic, antioxidant, anti-inflammatory and antihypertensive molecules. In the DE111 treatment group, the polyphenols trigonelline and 2,5-dihydroxybenzoic acid, orotic acid, the non-essential amino acid cystine and the lipokine 12,13-diHome were increased. DE111 also reduced acetylcholine levels in the ileostomy samples, and increased the expression of leucocyte recruiting proteins, antimicrobial peptides and intestinal alkaline phosphatases of the brush border in the small intestine. The combination of B. subtilis DE111 and the diet administered during the study increased the expression of the proteins phosphodiesterase ENPP7, ceramidase ASAH2 and the adipokine Zn-alpha-2-glycoprotein that are involved in fatty acid and lipid metabolism. Acute B. subtilis DE111 ingestion had limited detectable effect on the microbiome, with the main change being its increased presence. These findings support previous data suggesting a beneficial role of DE111 in digestion, metabolism, and immune health that appears to begin within hours of consumption.

Abstract
Tillaux fractures are fractures of the lateral margin of the distal tibia, usually reported in children between 12 and 14 years old. As intraarticular fractures, they require anatomic reduction and fixation to avoid posttraumatic complications. Since the injury mechanism is external rotation of the foot on the leg, these injuries are commonly associated with other fractures or ligamentous lesions. Currently, arthroscopy is being increasingly used to assist and improve surgical treatment of ankle fractures. The authors describe a 12-month follow-up of a rare case of a missed Tillaux fracture associated with syndesmosis injury in a 76-year-old polytrauma patient, successfully treated by arthroscopically-assisted reduction and internal fixation.

Burnout among Portuguese radiographers during the COVID-19 pandemic. Radiography (Lond) 2021; 27:1118-1123. [PMID: 34053854 PMCID: PMC8130549 DOI: 10.1016/j.radi.2021.05.001] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2020] [Revised: 05/07/2021] [Accepted: 05/09/2021] [Indexed: 11/18/2022]
Abstract
INTRODUCTION The COVID-19 pandemic has had a global impact, including in health services, placing health professionals under enormous tension, pressure, and stress. Professionals involved in the care, diagnosis, and treatment of COVID-19-infected patients have been subject to emotional and physical distress that can potentially enhance the development of occupational diseases. The aim of this study was to assess the impact of the COVID-19 pandemic on the incidence of burnout among Portuguese radiographers. METHODS This was a cross-sectional, quantitative study. Burnout levels were estimated using the Maslach Burnout Inventory-Human Services Survey, composed of 22 questions. Specific questions were developed to characterize the socio-demographic situation and the impact of the pandemic on the radiographers. Data were descriptively analyzed and Mann-Whitney and Kruskal-Wallis tests were used for correlation analysis. RESULTS The study sample comprised 386 radiographers, 68.7% of whom where female and 31.3% male. The mean sample age was 36.3 (±9.1) years. A total of 43.5% and 45.5% of subjects had a high level of emotional exhaustion and depersonalization, respectively, and 59.8% experienced low personal accomplishment. Altogether, 23.3% of study participants were at high risk of burnout in the three dimensions assessed and 77.2% in at least one. CONCLUSION Study results showed that radiographers were at high risk of developing burnout in the COVID-19 pandemic setting. Health institutions should actively monitor these professional's mental health and develop restorative strategies that enable their emotional wellbeing, preventing absenteeism and increasing patients' quality of care. IMPLICATIONS FOR PRACTICE Burnout of health professionals has a strong impact on health services organization, resulting in increased absenteeism and error probability, frequent work delays, low productivity and job satisfaction, inter- and intra-professional conflicts, high job turnover, high job quit, and decreased quality of care perceived by users.

Abstract
Introduction Obsessional slowness (OS) is a rare condition of disabling slow motor performance, first described in 1974, by Rachman, who documented 10 cases of “primary obsessional slowness”. Rachman argued that, although his patients with OS had Obsessive Compulsive Disorder (OCD), their motor symptoms were not related to the presence of motor-slowness-triggering obsessions/compulsions (e.g. checking and mental rituals). Whether OS truly is a distinct and “primary” entity is still a controversial issue, however. Objectives To present and discuss the phenomenology of OS. Methods Case reports of OS published in the literature, including Rachman’s descriptions. Results The literature on OS is extremely limited, with no published, large-scale descriptive studies or randomized controlled trials. Some authors doubt that OS is a “primary” condition, pointing out the clear overlap between OS and catatonia and emphasizing that the latter disorder also occurs in non-schizophrenic patients, for example, ones with OCD. Additionally, OCD and depression often co-occur. Thus, in severe cases, it may be challenging to disentangle the separate contribution of both disorders to psychomotor slowness. It is also crucial to exclude the possibility that a patience has juvenile parkinsonism or other causes of motor slowness before diagnosing him/her with OS, given that the diagnostic approaches and treatment strategies for OS and the aforementioned disorders differ. Conclusions OS seems to be a rare but often disabling motor manifestation of OCD, rather than a primary disease entity. However, some cases sit on the edge of current diagnostic criteria. Future research should help define OS more precisely. Disclosure No significant relationships.

Abstract
Introduction Depersonalization during panic attacks may be a feature of a subgroup of Panic disorder. Several studies suggest that such subgroup corresponds to a more clinically severe form of Panic Disorder, with earlier onset and a higher rate of comorbidity with other psychiatric disorders, such as obsessive-compulsive disorder and generalized anxiety disorder. It is also hypothesized that depersonalization during panic attacks may lead Panic disorder to evolve into Agoraphobia. Objectives To present the case report of a patient with severe Agoraphobia, whose only symptom of Panic disorder was depersonalization. Methods Description of a case report. Results We describe the case of a 20-year-old woman who developed Agoraphobia after a single panic attack, during a physical education class, at the age of 13, with depersonalization symptoms only. After the attack, the patient stopped playing sports and engaging in any kind of activity in the absence of a trusted person. At the age of 20, the patient will only travel alone in the immediacies of her home, sometimes missing classes, because she cannot get a ride from trusted acquaintances. She justifies such avoidances with her fear of feeling depersonalized again. Over the course of her illness, she denied having experienced any other symptoms of a panic attack. She was treated with Paroxetine 40mg daily and cognitive behavioral therapy, having improved. Conclusions We believe this case provides good insight into depersonalization in panic attacks, supporting the view that Panic disorder with depersonalization may be a distinct and more severe subgroup of Panic Disorder.

Abstract
Abstract
Background
The risk for Coronary Artery Disease (CAD) is determined by both genetic and environmental factors, as well as by the interaction between them. It is estimated that genetic factors could account for 40% to 55% of the existing variability among the population (inheritability). Therefore, some authors have advised that it is time we integrated genetic risk scores into clinical practice.
Aim
The aim of this study was to evaluate the magnitude of the association between an additive genetic risk score (aGRS) and CAD based on the cumulative number of risk alleles in these variants, and to estimate whether their use is valuable in clinical practice.
Methods
A case-control study was performed in a Portuguese population. We enrolled 3120 participants, of whom 1687 were CAD patients and 1433 were normal controls. Controls were paired to cases with respect to gender and age. 33 genetic variants known to be associated with CAD were selected, and an aGRS was calculated for each individual. The aGRS was further subdivided into deciles groups, in order to estimate the CAD risk in each decile, defined by the number of risk alleles. The magnitude of the risk (odds ratio) was calculated for each group by multiple logistic regression using the 5th decile as the reference group (median). In order to evaluate the ability of the aGRS to discriminate susceptibility to CAD, two genetic models were performed, the first with traditional risk factors (TRF) and second with TRF plus aGRS. The AUC of the two ROC curves was calculated.
Results
A higher prevalence of cases over controls became apparent from the 6th decile of the aGRS, reflecting the higher number of risk alleles present (see figure). The difference in CAD risk was only significant from the 6th decile, increasing gradually until the 10th decile. The odds ratio (OR) for the last decile related to 5th decile (median) was 1.87 (95% CI:1.36–2.56; p<0.0001). The first model yielded an AUC=0.738 (95% CI:0.720–0.755) and the second model was slightly more discriminative for CAD risk (AUC=0.748; 95% CI:0.730–0.765). The DeLong test was significant (p=0.0002).
Conclusion
Adding an aGRS to the non-genetic risk factors resulted in a modest improvement in the ability to discriminate the risk of CAD. Such improvement, even if statistically significant, does not appear to be of real value in clinical practice yet. We anticipate that with the development of further knowledge about different SNPs and their complex interactions, and with the inclusion of rare genetic variants, genetic risk scores will be better suited for use in a clinical setting.

Abstract
Abstract
Background
Noise is an important environmental risk factor. Industrial environments are rich in high-intensity infrasound (hi-IFS), which we have found to induce myocardial and coronary perivascular fibrosis in rats. Recently, a significant association between noise exposure and the incidence of atrial fibrillation (AF) was found in large cohort studies but the pathophysiology is unclear. Atrial fibrosis remains the cornerstone of atrial pathology in AF. Purpose: We hypothesized that rats exposed to hi-IFS develop atrial remodeling involving fibrosis and connexin 43, which we sought to evaluate. Material and Methods: Seventy-two Wistar rats, half exposed to hi-IFS (120dB, <20Hz) during a maximum period of 12 weeks and half age-matched controls, were studied. Atrial fibrosis was analyzed by Chromotrope-aniline blue staining. The immunohistochemical evaluation of Cx43 was performed using the polyclonal antibody connexin-43m diluted 1:1000 at 4ºC overnight. Digitized images were obtained with an optical microscope using 400× magnifications. The measurements were performed using image J software. A two-way ANOVA model was used to compare the groups. Results: The mean values of the ratio "atrial fibrosis / cardiomyocytes" increased to a maximum of 0,1095 ± 0,04 and 0,5408 ± 0,01, and of the ratio "CX43 / cardiomyocytes" decreased to 0,0834 ± 0,03 and 0,0966 ± 0,03, respectively in IFS-exposed rats and controls. IFS-exposed rats exhibited a significantly higher ratio of fibrosis (p < 0,001) and lower ratio of Cx43 (p = 0,009). Conclusion: High-intensity infrasound exposure triggers atrial remodeling in rat hearts. Whether this finding correlates to arrhythmogenic substrate in noise induced-AF is not known and reinforces the need for further experimental studies.

Abstract
Root-associated genes play an important role in plants. Despite the fact that there have been studies on root biology, information on genes that are specifically expressed or upregulated in roots is poorly collected. There exist very few databases dedicated to genes and promoters associated with root biology, preventing effective root-related studies. Therefore, we analyzed multiple types of omics data to identify root-associated genes in maize, soybean, and sorghum and constructed a comprehensive online database of these genes and their promoter sequences. This database creates a pivotal platform capable of stimulating and facilitating further studies on manipulating root growth and development.

Abstract
Abstract
Aims
The Acute Cardiac Care Association (ACCA)–European Association of Percutaneous Coronary Intervention (EAPCI) Registry on ST-elevation myocardial infarction (STEMI) of the EurObservational programme (EORP) of the European Society of Cardiology (ESC) registry aimed to determine the current state of the use of reperfusion therapy in ESC member and ESC affiliated countries and the adherence to ESC STEMI guidelines in patients with STEMI.
Methods and results
Between 1 January 2015 and 31 March 2018, a total of 11 462 patients admitted with an initial diagnosis of STEMI according to the 2012 ESC STEMI guidelines were enrolled. Individual patient data were collected across 196 centres and 29 countries. Among the centres, there were 136 percutaneous coronary intervention centres and 91 with cardiac surgery on-site. The majority of centres (129/196) were part of a STEMI network. The main objective of this study was to describe the demographic, clinical, and angiographic characteristics of patients with STEMI. Other objectives include to assess management patterns and in particular the current use of reperfusion therapies and to evaluate how recommendations of most recent STEMI European guidelines regarding reperfusion therapies and adjunctive pharmacological and non-pharmacological treatments are adopted in clinical practice and how their application can impact on patients’ outcomes. Patients will be followed for 1 year after admission.
Conclusion
The ESC ACCA-EAPCI EORP ACS STEMI registry is an international registry of care and outcomes of patients hospitalized with STEMI. It will provide insights into the contemporary patient profile, management patterns, and 1-year outcome of patients with STEMI.

Abstract
OBJECTIVE To evaluate the impact of indocyanine green (ICG) for assessing ureteric vascularity on the rate of uretero-enteric stricture formation after robot-assisted radical cystectomy (RARC) with intracorporeal urinary diversion (ICUD). PATIENTS AND METHODS We identified 179 patients undergoing RARC and ICUD between January 2014 and May 2017, and divided the patients into two groups based on the utilisation of ICG for the assessment of ureteric vascularity (non-ICG group and ICG group). We retrospectively reviewed the medical records to identify the length of ureter excised. Demographic, perioperative outcomes (including 90-day complications and readmissions), and the rate of uretero-enteric stricture were compared between the two groups. The two groups were compared using the t-test for continuous variables and the chi-squared test for categorical variables. A P < 0.05 was considered statistically significant. RESULTS A total of 132 and 47 patients were in the non-ICG group and the ICG group, respectively. There were no differences in baseline characteristics and perioperative outcomes including operating time, estimated blood loss, and length of stay. The ICG group was associated with a greater length of ureter being excised during the uretero-enteric anastomosis and a greater proportion of patients having long segment (>5 cm) ureteric resection. The median follow-up was 14 and 12 months in the non-ICG and ICG groups, respectively. The ICG group was associated with no uretero-enteric strictures compared to a per-patient stricture rate of 10.6% and a per-ureter stricture rate of 6.6% in the non-ICG group (P = 0.020 and P = 0.013, respectively). CONCLUSION The use of ICG fluorescence to assess distal ureteric vascularity during RARC and ICUD may reduce the risk of ischaemic uretero-enteric strictures. The technique is simple, safe, and reproducible. Larger studies with longer follow-up are needed to confirm our findings.

Abstract
The low-velocity layer (LVL) atop the 410-km discontinuity has been widely attributed to dehydration melting. In this study, we experimentally reproduced the wadsleyite-to-olivine phase transformation in the upwelling mantle across the 410-km discontinuity and investigated in situ the sound wave velocity during partial melting of hydrous peridotite. Our seismic velocity model indicates that the globally observed negative Vs anomaly (−4%) can be explained by a 0.7% melt fraction in peridotite at the base of the upper mantle. The produced melt is richer in FeO (~33 wt.%) and H2O (~16.5 wt.%) and its density is determined to be 3.56–3.74 g cm−3. The water content of this gravitationally stable melt in the LVL corresponds to a total water content in the mantle transition zone of 0.22 ± 0.02 wt.%. Such values agree with estimations based on magneto-telluric observations. A 56–60 km thick low velocity layer exists at the base of the Earth’s upper mantle. Here, the authors experimentally reproduced the wadsleyite-to-olivine transition in the upwelling mantle and show that the low velocity anomaly can be explained by melting of hydrous peridotite.

Abstract
BACKGROUND Treatment for Freiberg disease has been largely conservative despite availability of various operative options for severe or refractory cases. The aim of this study was to evaluate the long-term results of pediatric patients with symptomatic Freiberg disease treated with intra-articular dorsal wedge osteotomy. METHODS Pediatric patients treated for Freiberg disease with surgery between January 1982 and 1999 were identified and selected for long-term clinical evaluation. Patients were evaluated regarding operative satisfaction and clinical outcome, performed according to the American Orthopaedic Foot & Ankle Society (AOFAS) lesser toe metatarsophalangeal-interphalangeal scale and range of motion (ROM) of metatarsophalangeal (MTP) joint. Patients had radiographic assessment of degenerative joint status with anteroposterior and oblique foot x-ray. Twenty patients (18 female, 2 male; mean age 15.2 years; range 12-17 years) were identified. The mean follow-up period was 23.4 (range 15-32) years. RESULTS The clinical outcomes of our patients were classified as excellent in 16 (80%) and good in 4 (20%). The AOFAS mean score was 96.8 (range 91-100) points at the last clinical appointment. A negative correlation between AOFAS score and time of follow-up (r's = -0.61, P < .001) was found. Also, a strong negative correlation was found between Smillie classification and AOFAS final score (r's = -0.88, P < .001). CONCLUSION The patients were very satisfied with pain and quality of life at a mean follow-up time of 23.4 years. To our knowledge, this is the first long-term follow-up report supporting the procedure described by Gauthier and Elbaz as a good option for operative treatment of Freiberg disease. LEVEL OF EVIDENCE Level IV, retrospective case series.

Abstract
AIM The present study aims (1) to provide reference percentile charts for the following measures of Physical Fitness (PF): the sit-and-reach, handgrip, standing long jump, 50 yards' dash, 4x10m shuttle run and 1-mile run/walk tests in children aged 6 to 10 years, and (2) to compare the performance of the Portuguese children with their age- and sex peers. METHODS A total of 3804 Portuguese children (1985 boys and 1819 girls) aged 6-10 years old participated in this study. The sample was stratified from 20 public elementary schools and children were randomly selected in each school. Charts were separately built for each sex using the LMS method. RESULTS Boys showed better results than girls in handgrip, standing long jump, 50 yards' dash, 4x10 m shuttle run and 1-mile run/walk, while girls are better performers than boys in sit-and-reach. CONCLUSION Age- and gender- percentiles for a set of physical fitness tests for 6-10 year old (primary school) Portuguese children have been established. Boys showed greater overall PF than girls, except in the flexibility test, in which girls performed better. The reported normative values provide ample opportunities to accurately detect individual changes during childhood. These reference values are especially important in healthcare and educational settings, and can be added to the worldwide literature on physical fitness values in children.

Abstract
BACKGROUND Non-opioid psychotherapeutic medications significantly increase the risk of opioid overdose-related deaths. We prospectively followed HIV-infected indigent adults sampled from the community to examine rates of and factors associated with non-medical use of benzodiazepines, muscle relaxants, and prescription stimulants. METHODS We interviewed participants quarterly for 2 years about alcohol and illicit substance use; depression; use of prescribed opioid analgesics, benzodiazepines and muscle relaxants; opioid analgesic misuse; and non-medical use (i.e., use without a prescription) of benzodiazepines, muscle relaxants, and prescription stimulants. Using mixed-effects multivariate logistic regression, we determined factors associated with non-medical use of benzodiazepines, muscle relaxants, and prescription stimulants. RESULTS Among the 296 participants at enrollment, 52.0% reported taking opioid analgesics that had been prescribed, 17.9% took benzodiazepines that had been prescribed, and 8.1% took muscle relaxants that had been prescribed. Over the 2-year study interval, 53.4% reported prescription opioid misuse, 25.3% reported non-medical use of benzodiazepines, 11.5% reported non-medical use of muscle relaxants, and 6.1% reported non-medical use of prescription stimulants. In multivariable analysis, opioid analgesic misuse in the past 90 days was associated with non-medical use of benzodiazepines, muscle relaxants, and prescription stimulants during the same time interval. Illicit substance use and depression were not associated with non-medical use of these medications. CONCLUSIONS Prescription opioid analgesic misuse is associated with non-medical use of other psychotherapeutic medications. Health care providers should monitor for non-medical use of a broad array of psychoactive medications among high-risk populations to minimize harm.

Abstract
PURPOSE To review the results of scapholunate ligament reconstruction using a flexor carpi radialis tendon graft. METHODS We performed a retrospective review of 22 patients with post-traumatic scapholunate instability who were treated with a modification of the Brunelli, a flexor carpi radialis tendon graft. RESULTS The mean follow-up was 61 months. The average age was 40 years. The average loss of flexion was 23° and of extension was 22° compared with the contralateral side. Grip strength averaged 67% of the nonoperated side. All patients except 2 returned to work. Degenerative changes were seen in 3 patients at the time of revision. Complications occurred in 2 patients and included avascular necrosis of the scaphoid. CONCLUSIONS Perfect biomechanical reconstruction might not be possible for scapholunate dissociation. Our results show, however, that ligament reconstruction led to satisfactory results from the patient's point of view. TYPE OF STUDY/LEVEL OF EVIDENCE Therapeutic IV.

Abstract
Obsessive-compulsive disorder (OCD) is achronic psychiatric disorder characterized by recurrent intrusive thoughts and/or repetitive compulsory behaviors. This psychiatric disorder is known to be stress responsive, as symptoms increase during periods of stress but also because stressful events may precede the onset of OCD. However, only a few and inconsistent reports have been published about the stress perception and the stress-response in these patients. Herein, we have characterized the correlations of OCD symptoms with basal serum cortisol levels and scores in a stress perceived questionnaire (PSS-10). The present data reveals that cortisol levels and the stress scores in the PSS-10 were significantly higher in OCD patients that in controls. Moreover, stress levels self-reported by patients using the PSS-10 correlated positively with OCD severity in the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS). Interestingly, PSS-10 scores correlated with the obsessive component, but not with the compulsive component, of Y-BOCS. These results confirm that stress is relevant in the context of OCD, particularly for the obsessive symptomatology.

Abstract
OBJECTIVE To assess the efficacy of lamivudine treatment on hepatitis B e antigen (HBeAg) and/or hepatitis B surface antigen (HBsAg) seroconversion, on other virological and serological markers of response including hepatitis B virus (HBV) DNA and serum aminotransferases, and the safety of lamivudine treatment in hepatitis B patients. PATIENTS This phase III open-label study evaluated the virological and biochemical response to lamivudine in 70 Portuguese patients with HBeAg positive chronic hepatitis B. Patients were treated with lamivudine 100mg once daily for 12 months. METHODS Antiviral activity was assessed by measuring alanine aminotransferase (ALT)/aspartate aminotransferase (AST) levels at all protocol visits, and hepatitis B serology and HBV DNA were performed at baseline and at month 12 visits. Evaluation of safety and tolerance was based on clinical adverse events and laboratory analyses. RESULTS The primary endpoint was virological response at month 12, defined as loss of detectable HBeAg from serum with a reduction of HBV DNA to undetectable levels, and this was observed in 19/69 (27.5%) of patients. Almost half of the patients were HBV DNA negative by this time. Mean ALT values decreased steadily during treatment and by 12 months 61% of patients had values within the normal range. HBeAg seroconversion (HBeAg negative, HBeAb positive) was achieved in 27.9% of patients by 12 months, although all patients remained HBsAg positive. CONCLUSION Lamivudine was well tolerated and the incidence of adverse events was similar to those reported in previous studies. Lamivudine treatment resulted in virological and biochemical improvements in HBeAg positive chronic hepatitis B patients, with HBeAg seroconversion in one-third of patients.

Abstract
Radial osteotomy is currently advocated for patients with Lichtman’s stages II and IIIA of Kienböck’s disease; its place in the treatment of patients with stage IIIB disease remains controversial. The purpose of this study was to evaluate the medium-term results of this procedure and to compare the outcome in patients with stage IIIB disease and those with earlier stages (II and IIIA). A total of 18 patients (18 osteotomies) were evaluated both clinically and radiologically at a mean follow-up of 10.3 years (4 to 18). Range of movement, grip strength and pain improved significantly in all patients; the functional score (Nakamura Scoring System (NSSK)) was high and self-reported disability (Disabilities of Arm, Shoulder and Hand questionnaire) was low at the final follow-up in all patients evaluated. Patients with stage IIIB disease, however, had a significantly lower grip strength, lower NSSK scores and higher disability than those in less advanced stages. Radiological progression of the disease was not noted in either group, despite the stage. Radial osteotomy seems effective in halting the progression of disease and improving symptoms in stages II, IIIA and IIIB. Patients with less advanced disease should be expected to have better clinical results.

Abstract
IntroductionOlfactory reference syndrome (ORS), first described by Pryse-Phillips in 1971, is a rare psychiatric condition whose defining characteristic is a preoccupation with the belief that one emits a foul or offensive body odor, which is not perceived by others. Although the existence of ORS is now widely accepted, current classifications do not explicitly mention ORS as an independent category, but consider it as a delusional disorder, somatic type. Nonetheless, given this syndrome's consistent description along time and cultures, and the associated substancial distress and disability, many authors debate the possibility of a new classification in order to establish its nosological status.Objectives/aimsThe aim of this paper is to show and discuss some troublesome and complex issues of diagnosis and management of patients with ORS.MethodsHerein we report a case of a 38-year-old woman who presented with ORS.Results/conclusionsImprovement in ORS can take place, in some extent, with a variety of different modalities of treatment, with the disorder responding to antidepressants and psychotherapy more frequently than to neuroleptics. Data on ORS are still limited and more research in this field is needed. Awareness of this particular diagnosis allows appropriate treatment to be administered.

Abstract
OBJECTIVES A discrepancy in crown-rump length (CRL) and/or nuchal translucency thickness (NT) between monochorionic twins has been found to be associated with an increased risk of twin-twin transfusion syndrome (TTTS). As one of the most plausible mechanisms for increased NT is hemodynamic imbalance and cardiac dysfunction, indirectly manifested by abnormal blood flow in the ductus venosus (DV), we aimed to clarify the role of DV blood flow assessment in identifying those monochorionic twins more prone to develop TTTS. METHODS We present 99 cases of monochorionic diamniotic twin pregnancies in which CRL, NT and DV blood flow were evaluated at 11-14 weeks' gestation. RESULTS Discrepant values of CRL were not predictive of TTTS development. Intertwin NT discrepancy >or= 0.6 mm had a sensitivity of 50.0% and a specificity of 92.0%. The presence of at least one abnormal blood flow waveform in the DV was associated with a relative risk for developing TTTS of 11.86 (95% CI, 3.05-57.45), with a sensitivity of 75.0% and a specificity of 92.0%. The combination of abnormal DV blood flow with NT discrepancy >or= 0.6 mm yielded a relative risk for the development of TTTS of 21 (95% CI, 5.47-98.33). CONCLUSIONS Both intertwin discrepancy in NT and abnormal flow in the DV in monochorionic twins may represent early manifestations of hemodynamic imbalance between donor and recipient. In these pregnancies, in addition to NT measurement at 11-14 weeks, the Doppler assessment of DV blood flow significantly increases the performance of screening for those at risk of developing TTTS.

Abstract
BACKGROUND Skeletal maturity is used to evaluate biological maturity status. Information about the association between socio-economic status (SES) and skeletal maturity is limited in Portugal. AIMS The aim of this study is to document the skeletal maturity of youths in Madeira and to evaluate variation in maturity associated with SES. SUBJECTS AND METHODS The study involved 507 subjects (256 boys and 251 girls) from the Madeira Growth Study, a mixed-longitudinal study of five cohorts (8, 10, 12, 14 and 16 years of age) followed at yearly intervals over 3 years (1996-1998). A total of 1493 observations were made. Skeletal age was estimated from radiographs of the hand and wrist using the Tanner-Whitehouse 2 method (TW2). Social class rankings were based on method. Five social rankings were subsequently grouped into three SES categories: high, average and low. RESULTS Median for the radius, ulna and short finger bones (RUS scores) in the total sample of boys and girls increased curvilinearly across age whereas median for the 7 (without pisiform) carpal bones (Carpal scores) increased almost linearly. The 20-bone maturity scores demonstrated distinctive trends by gender: the medians for boys increased almost linearly while the medians for girls increased curvilinearly. SES differences were minimal. Only among children aged 10-11 years were high SES boys and girls advanced in skeletal maturity. Madeira adolescents were advanced in skeletal maturity compared with Belgian reference values. CONCLUSION The data suggests population variation in TW2 estimates of skeletal maturation. Skeletal maturity was not related to SES in youths from Madeira.

Abstract
e20736 Background: Resillience is the ability to successfully cope with change or misfortune, allowing a person or a group to regain balance and keep going despite adversity and also to find meaning amidst confusion and tumult. It is a positive personality characteristic that enhances individual and group adaptation. Very scanty data exists regarding its quantification and distribution in cancer patients. The objective of this study is to evaluate and describe resilience scores in a population of ambulatory solid tumors cancer patients receiving chemotherapy treatment. Methods: Individual Resillience scores were measured by the Wagnild and Young Scale, validated for portuguese language from Brazil. It is composed by 25-item questions, scored on a 7-point scale from 1 = disagree, to 7 = agree, with all items worded positively. Possible scores range from 25 to 175 with higher scores reflecting higher resilience. During the year 2008, this scale was applied to 48 ambulatory solid tumor cancer patients in chemotherapy treatment at Oncosinos / Hospital Regina in Novo Hamburgo, Brazil. The study was approved by the Ethics comitte and all patiens signed the informed consent form. Results: The mean age of patients was 52 years (19–76) and 34 (70%) were women. The most common cancer types were: breast (48%), colo-rectal (21%) and prostate (8%). Most patients (47%) had stage IV disease and were in palliative chemotherapy treatment. Stage III cancer was present in 40% and stages I and II in 13% of patients. The mean score of resilience was 141+ 12 (101–174). The scores demosntrated a normal statistical distribution. No statistical differences in the mean resillience scores were detected between groups of patients as defined by: sex (P=0.11), age > or < 50 years (P=0.9), cancer type (P= 0.78), disease staging (P= 0.9), or the chemotherapy treatment intention, if palliative or curative (P=0.91). Conclusions: The resilience scores in this cohort of patients display a statistically normal distribution. Our results suggest that the total resillience score is an intrinsic individual characteristic that is independent of cancer stage, cancer type, age and sex of the patients. Further research is necessary to clarify the implications of these findings. No significant financial relationships to disclose.

Abstract
"Downhill" varices or upper esophageal varices are a rare cause of proximal digestive tract hemorrhage with only 16 cases described in the literature. In our series, hemorrhage due to "downhill" varices represents 0.1% of all acute esophageal variceal bleeding. Their etiology differs from that of the usual "uphill" varices secondary to portal hypertension, and the clinical management should be directed to vascular obstruction if present. We report a case of an 89-year-old male with hemorrhagic "downhill" varices not associated, as usually, with superior vena cava obstruction or compression, but with severe pulmonary hypertension and drug-related hemorrhagic risk factors, whose removal proved sufficient to prevent rebleeding.

Abstract
BACKGROUND/AIMS Variceal bleeding is still associated with high mortality and balloon tamponade may be a lifesaving measure when endoscopic therapy is not available or feasible. The risk of esophageal perforation with balloon tamponade after endoscopic therapy is still uncertain. The aims of the study were to investigate balloon tamponade effectiveness and safety after endoscopic therapy. METHODOLOGY Retrospective analysis of 100 consecutive episodes of acute variceal bleeding treated with the Sengstaken-Blakemore tube. RESULTS Balloon tamponade had an overall effectiveness of 61%. The Child-Pugh score was significantly higher in patients who failed balloon tamponade. In 48 cases balloon tamponade was preceded by failure of endoscopic therapy. Balloon tamponade was more effective if a previous attempt to perform endoscopic therapy happened (75% vs. 48%; p = 0.006). Aspiration was the most frequent complication. No cases of esophageal perforation were registered. CONCLUSIONS Currently balloon tamponade is only used as a temporary bridge to other strategies, when other forms of hemostatic therapies do not succeed. Balloon tamponade was more effective in patients with less severe hepatic dysfunction. Previous attempts to perform endoscopic therapy may augment tamponade effectiveness without increasing the risk of esophageal perforation.
