Abstract
Background Loss of internal rotation remains an issue after reverse total shoulder arthroplasty (RTSA). Our goal is to define the expected functional internal rotation after RTSA using the Activities of Daily Living which require Internal Rotation (ADLIR) score in a homogenous population of patients treated with RTSA. Methods 35 patients with a minimum follow-up of two years after RTSA were evaluated using the ADLIR and Constant-Murley questionnaires. A correlation between the ADLIR and Constant score was investigated and the internal validity of the ADLIR score used in a RTSA patient population was measured using Cronbach's alpha coefficient. The impact of internal rotation on the total rotational arc of motion was defined. Results Excellent results were recorded for both the Constant score (79 ± 18) and ADLIR score (88 ± 16). Pearson's correlation coefficient was r = 0,84 (p-value <0,001). The ADLIR score showed a high reliability for all questions. Conclusions The ADLIR score has proven to be a useful addition in the post-operative evaluation of patients treated with RTSA. Further studies are needed to investigate the evolution of the ADLIR score from pre- to postoperatively in order to determine the clinical and predictive value of this score. Level of evidence Level IV - Observational study.

Abstract
Abstract
Background
The role of intra-aortic balloon pump (IABP) in advanced heart failure (HF) treatment is still under debate. Some heart transplant (HTx) candidates on the waiting list require mechanical support, and IABP may be the simple and most available device.
Purpose
Describe the impact of IABP treatment in advanced HF patients who underwent HTx.
Methods
We retrospectively analysis patients who underwent HTx from a single center intensive care unit (ICU), between 2009 and 2018, to evaluate the use of IABP as bridge therapy. Selection included decompensated chronic HF patients that required intensive care with optimized intravenous drugs before IABP placement. Exclusion criteria were acute myocardial infarction or cardiac surgery 90 days prior to admission, and implant of ventricular assist device before HTx.
Results
We included 134 HF patients with IABP therapy before HTx. Insertion site was exclusively femoral. Mean time of IABP onset to HTx were 26±21 days, and hospital admission to HTx 65±45 days. The main cardiomyopathy etiology was Chagas Disease (46%) and mean LVEF was 23±6% (TABLE 1). Clinical and laboratory data were compared before and 96 hours after IABP therapy. Mean central venous oxygen saturation (SvO2) increased from 49.7±14.6% to 67.4±11.3% (p<0.001), creatinine decreased from 1.77±0.9 mg/dL to 1.40±0.6 mg/dL (p<0.001), and urine output increased from 1552±886 mL/24h to 2189±1029 mL/24h (p<0.001). These differences were sustained or improved until the day before HTx (FIGURE 1). After 96 hours dobutamine was maintained in 98% of patients, nitroprusside increased from 56% to 67%, milrinone decreased from 26% to 20%, and norepinephrine decreased from 18% to 3%. Significant IABP complications were few (5.2%; n=7: 3 infections, 2 major bleeding, 2 arterial injury).
Conclusion
In this single center ICU sample, IABP improved hemodynamic status and renal function in refractory HF patients waiting for HTx. IABP can be a reasonable, available and effective bridging therapy.

Abstract
Purpose The lockdown imposed in France to cope with the COronaVIrus Disease 2019 (COVID-19) outbreak has led to major changes in the lifestyle of French citizens. The aim of our study was to study its impact on activity related to emergencies in hand and upper limb trauma in comparison to the same reference period in 2019. Material and methods All consecutive patients consulting for upper limb injury requiring urgent care at Georges-Pompidou European Hospital (HEGP), France, during the lockdown period (case group) and the equivalent period in 2019 (control group) were included. In each group, the type of accident, the anatomical location of the injury, and the treatment were reported and compared. Results Two hundred seventy-five patients were included in the case group in comparison to 784 patients in the control group. We observed a two-third decrease in the rate of upper limb emergencies (− 64.9%) in particular a drastic drop in the rate of road, work, and leisure accidents (10.4% vs 14.3%, p = 0.1151; 10.0% vs 22.6%, p < 0.0001; 13.1% vs 30.8%, p < 0.0001, respectively), and a clear increase in domestic accidents (66.5% vs 32.3%, p < 0.0001). The aetiologies were more dominated by lacerations of soft tissues (48.4%, vs 38.3%, p = 0.0034) and infections (8.7% vs 5.1%, p = 0.0299) with an increase in the indications for surgical management (51.2% vs 36.9%, p < 0.0001). Conversely, we observed fewer consultations for joint injuries (20.7% vs 30.7%, p = 0.0015) and fractures (22.2% vs 25.9%, p = 0.2210). Conclusion The lockdown imposed in France has changes the etiologies and the management of hand and upper limb emergencies.

Abstract
Desktop dust has been studied as a source of food allergen, but not as a source of potential aeroallergen exposure. Thirty-six wiped samples from desktop surfaces were collected from preschools and schools. Samples were analyzed for detectable levels of common aeroallergens including Alternaria, cockroach, dog, dust mite, cat, mouse, and rat allergens by immunoassay. Mouse allergen was the most prevalent, detectable in 97.2% of samples. Cat allergen was detectable in 80.6% of samples, and dog allergen was detectable in 77.8% of samples. Other allergens were not as prevalent. Mouse was the only allergen that was highly correlated with settled floor dust collected from the same rooms (r = 0.721, P < 0.001). This is the first study to detect aeroallergens on desktop surfaces by using moist wipes. Allergens for mouse, cat, and dog were highly detectable in wipes with mouse desktop surface levels correlating with levels in vacuumed floor dust.

Abstract
Anti-myelin basic protein (MBP) antibodies in pediatric-onset MS and controls were characterized. Serum samples were obtained from 94 children with MS and 106 controls. Paired CSF and serum were obtained from 25 children with MS at time of their initial episode of acute demyelinating syndrome (ADS). Complementary assays were applied across samples to evaluate the presence, and the physical binding properties, of anti-MBP antibodies. While the prevalence and titers of serum anti-MBP antibodies against both immature and mature forms of MBP were similar in children with MS and in controls, binding characteristics and formal Surface Plasmon Resonance (SPR) studies indicated surprisingly high binding affinities of all pediatric anti-MBP antibodies. Serum levels of anti-MBP antibodies correlated significantly with their CSF levels, and their presence in children with MS was associated with significantly increased risk of an acute disseminated encephalomyelitis-like initial clinical presentation. While antibodies to both immature and mature forms of MBP can be present as part of the normal pediatric humoral repertoire, these anti-myelin antibodies are of surprisingly high affinity, can access the CNS during inflammation, and have the capacity to modulate disease expression. Our findings identify an immune mechanism that could contribute to the observed heterogeneity in spectrum of clinical presentations in early-onset MS.

Abstract
OBJECTIVE To evaluate elastic properties of conduit arteries in asymptomatic patients who have severe chronic aortic regurgitation. METHODS Twelve healthy volunteers aged 30+/-1 years (control group) and 14 asymptomatic patients with severe aortic regurgitation aged 29+/-2 years and left ventricular ejection fraction of 0.61+/-0.02 (radioisotope ventriculography) were studied. High-resolution ultrasonography was performed to measure the systolic and diastolic diameters of the common carotid artery. Simultaneous measurement of blood pressure enabled the calculation of arterial compliance and distensibility. RESULTS No differences were observed between patients with aortic regurgitation and the control group concerning age, sex, body surface, and mean blood pressure. Pulse pressure was significantly higher in the aortic regurgitation group compared with that in the control group (78+/-3 versus 48+/-1mmHg, P<0.01). Arterial compliance and distensibility were significantly greater in the aortic regurgitation group compared with that in the control group (11.0+/-0.8 versus 8.1+/-0.7 10(-10) N-1 m4, P=0.01 e and 39.3+/-2.6 versus 31.1+/-2.0 10(-6) N-1 m2, P=0.02, respectively). CONCLUSION Patients with chronic aortic regurgitation have increased arterial distensibility. Greater vascular compliance, to lessen the impact of systolic volume ejected into conduit arteries, represents a compensatory mechanism in left ventricular and arterial system coupling.

Abstract
We present the initial experience with the use of inferior epigastric artery as a free graft for myocardial revascularization in a series of 41 patients operated on between 1987 and 1989 to show the clinical and angiographic results. Of the 41 patients, 29 were male, 12 female, with ages ranging from 33 to 72 years, and weights from 50 to 86 kg. The inferior epigastric artery grafts were predominantly employed to the anterior interventricular branch and diagonal branch. The proximal anastomosis into the aorta was done directly or with a patch of vein or pericardium. The 32 patients who survived had mean follow-up of 82 months and 22 are in functional class I, 8 in class II and 2 in class III of angina. The early patency rate was: inferior epigastric artery-anterior interventricular branch, 85.7% and inferior epigastric artery-diagonal branch. 85.7%. Sixteen patients underwent angiographic study at a mean follow-up of 81.2 months and the patency rate to the anterior interventricular branch was 77.7% and to the diagonal branch was 100%. Three patients with early occluded inferior epigastric artery were reoperated on 3, 3 and 11 months after the operation. A filiform lumen of the graft and a small ostium in the aorta was found and explained the imperfection of the direct anastomosis due to unbalance thickness of the graft and the aortic wall. Therefore it is occluded that the inferior epigastric artery is an alternative arterial graft for myocardial revascularization and that the use of a vein or pericardium patch can help the proximal anastomosis and improve potency of the graft.

Abstract
A 21-year-old white man presented with cardiogenic shock and refractory pulmonary congestion. At the transthoracic echocardiogram a subvalvar left ventricular aneurysm of the inferior wall with severe mitral regurgitation was observed. The outcome was favorable after surgical correction of the mitral regurgitation and of the subvalvar aneurysm. We emphasize that, whenever possible, valvar repair is better than mitral replacement, since annulus tissue fragility causes suturing of the mitral prosthesis to be difficult.

Abstract
Conduit artery distensibility affects the pulsatile component of afterload and may contribute to impaired left ventricular function in patients with congestive heart failure (CHF). The objectives of this study were to (1) determine whether arterial distensibility is reduced in patients with CHF, and (2) determine whether decreased arterial compliance is related to an abnormality in vascular wall structure (i.e., wall thickness or excessive levels of circulating neurohumoral vasoconstrictors, or both). The study participants included 40 patients with CHF secondary to idiopathic dilated cardiomyopathy and 33 age-matched healthy volunteers. High-resolution ultrasonography was performed to directly visualize the common carotid artery and measure its diameter and wall thickness. Its elastic properties were determined by relating changes in arterial diameter to changes in pressure generated with each heart beat. Carotid artery distensibility was less (14.1 +/- 1.1 vs 25.3 +/- 1.6 10(-6).N-1.m2, p < 0.001) and Young's modulus of elasticity was greater (3.99 +/- 0.51 vs 2.29 +/- 0.23 10(5).N.m-2, p < 0.005) in patients with CHF than in normal subjects. Also, carotid artery wall thickness was increased in patients with CHF. When the entire population was considered, age, wall thickness, and plasma norepinephrine and aldosterone concentrations correlated inversely with distensibility, whereas age and plasma norepinephrine concentration correlated directly with elasticity. Among normal subjects, only age correlated inversely with distensibility; among patients with CHF, only plasma norepinephrine concentration correlated with elasticity. It is concluded that carotid artery distensibility is reduced in patients with CHF.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Fulminant hepatic failure is a complication of severe cardiocirculatory failure, with high morbidity and mortality, and is frequently misdiagnosed as fulminant viral hepatitis. We report three cases of patients with chronic severe heart failure who developed cardiogenic shock complicated by elevation of aminotransferase levels above 1,000 soon after the most severe episode of hypotension. All the three patients presented regression of hepatic enzymes 72h after admission. Two patients developed hepatic encephalopathy and renal failure. One underwent the implantation of an artificial left ventricle, followed by orthotopic heart transplantation. One died of systemic multiple organ failure, after he had showed improvement on his hepatic profile, and one was sent to the ward, after 15 days with marked improvement on his clinical status and no signs of hepatic disease.

Abstract
PURPOSE To evaluate the toxicity of thiocyanate induced by the infusion of sodium nitroprusside in patients with severe congestive failure. METHODS We studied 23 patients with congestive heart failure, in class IV (NYHA) under continuous infusion of sodium nitroprusside with doses varying between 0.5 and 5.5 micrograms/kg/min. Clinical evaluation, thiocyanate serum dosage and laboratorial evaluation of renal, hepatic and pulmonary functions were done. RESULTS Seventeen patients (74%) presented toxic levels of thiocyanate (over 10 micrograms/ml), with the average of 29.9 +/- 4.4 micrograms/ml. Only renal function was related to the presence of intoxication. Clinical evaluation was not accurate to diagnose the thiocyanate toxicity in the patients. CONCLUSION Sodium nitroprusside is potentially toxic, especially when the renal function is abnormal. Thiocyanate dosage is useful in diagnosing nitroprusside induced toxicity and then it contributes to an adequate treatment and prevention of clinical toxicity.

Abstract
A healthy 44 year-old male patient presented a calcified mass in the middle mediastinum on a chest film. During diagnostic investigation cineangiograms showed a rupture of the left sinus of Valsalva forming a large pseudoaneurysm that produced important distortion of the left coronary artery and it's main branches. The patient was submitted to surgical repair through the closure of the orifice of the ruptured left sinus of Valsalva with a bovine pericardium patch. The subepicardium was filled with organized thrombi which were removed. He was discharged from the hospital after uncomplicated postoperative course. Pathological examination of the aortic fragment did not yield the etiology of the rupture.

Abstract
The inferior epigastric artery was used as a free graft for direct myocardial revascularization in 22 patients from October 1987 to July 1988. The artery was used either alone or along with internal mammary artery or saphenous vein grafts. The inferior epigastric artery was dissected through an infraumbilical incision without entrance into the peritoneal cavity. The results depend on the technique used for the aortoepigastric anastomosis. When a segment of saphenous vein or a patch of bovine pericardium was sutured to a large aortic orifice with the inferior epigastric artery previously anastomosed to these patches, the patency rate of the free grafts in the early postoperative period was 100%. Histologic examination showed identical structure of the inferior epigastric artery and the internal mammary artery. Application of the inferior epigastric artery is an attempt to increase the use of arterial grafts for myocardial revascularization.

Abstract
Esophageal echocardiography has been developed for use in patients with chronic obstructive pulmonary disease and is a safe diagnostic procedure which provides high resolution mirror image echoes of many cardiac structures. Conventional anterior and esophageal echocardiograms were performed in 38 subjects. Esophageal echoes were of diagnostic quality in all 38 subjects, anterior echoes were of diagnostic quality in only 18. Measurements from anterior and esophageal echocardiograms correlated well for aortic valve diameter (r = 0.87), left atrium diameter (r = 0.96), mitral valve EF slope (r = 0.97) and less well for aortic root diameter (r = 0.69).
