RESUMO

PURPOSE: We investigated whether twice-daily administration of a bilayer tablet formulation of tramadol (35% immediate-release [IR] and 65% sustained-release) is as effective as four-times-daily IR tramadol capsules for managing cancer pain. METHODS: This randomized, double-blind, double-dummy, active-comparator, non-inferiority study enrolled opioid-naïve patients using non-steroidal anti-inflammatory drugs or acetaminophen (paracetamol) to manage cancer pain and self-reported pain (mean value over 3 days ≥ 25 mm on a 100-mm visual analog scale [VAS]). Patients were randomized to either bilayer tablets or IR capsules for 14 days. The starting dose was 100 mg/day and could be escalated to 300 mg/day. The primary endpoint was the change in VAS (averaged over 3 days) for pain at rest from baseline to end of treatment/discontinuation. RESULTS: Overall, 251 patients were randomized. The baseline mean VAS at rest was 47.67 mm (range: 25.6-82.7 mm). In the full analysis set, the adjusted mean change in VAS was - 22.07 and - 19.08 mm in the bilayer tablet (n = 124) and IR capsule (n = 120) groups, respectively. The adjusted mean difference was - 2.99 mm (95% confidence interval [CI] - 7.96 to 1.99 mm). The upper 95% CI was less than the predefined non-inferiority margin of 7.5 mm. Other efficacy outcomes were similar in both groups. Adverse events were reported for 97/126 (77.0%) and 101/125 (80.8%) patients in the bilayer tablet and IR capsule groups, respectively. CONCLUSION: Twice-daily administration of bilayer tramadol tablets was as effective as four-times-daily administration of IR capsules regarding the improvement in pain VAS, with comparable safety outcomes. CLINICAL TRIAL REGISTRATION: JapicCTI-184143/jRCT2080224082 (October 5, 2018).

RESUMO

Left main coronary artery ostial atresia (LMCAOA) is an extremely rare condition. Here, we report the case of a 14-year-old boy with Noonan syndrome-like disorder in whom LMCAOA was detected following cardiopulmonary arrest. The patient had been diagnosed with Noonan syndrome-like disorder with a pathogenic splice site variant of CBL c.1228-2 A > G. He suddenly collapsed when he was running. After administering two electric shocks using an automated external defibrillator, the patient's heartbeat resumed. Cardiac catheterization confirmed the diagnosis of LMCAOA. Left main coronary artery angioplasty was performed. The patient was discharged without neurological sequelae. Brain magnetic resonance imaging revealed asymptomatic Moyamoya disease. In addition, RNF213 c.14429 G > A p.R4810K was identified. There are no reports on congenital coronary malformations of compound variations of RNF213 and CBL. In contrast, the RNF213 p.R4810K polymorphism has been established as a risk factor for angina pectoris and myocardial infarction in adults, and several congenital coronary malformations due to genetic abnormalities within the RAS/MAPK signaling pathway have been reported. This report aims to highlight the risk of sudden death in patients with RASopathy and RNF213 p.R4810K polymorphism and emphasize the significance of actively searching for coronary artery morphological abnormalities in these patients.

RESUMO

Background The close relationship between earlobe creases (ELC) and the presence of coronary artery disease (CAD) has been reported. In addition, this study aimed to determine associations between ELC and the presence, extent, and severity of coronary atherosclerosis assessed by coronary angiography in non-elderly and elderly patients. Methods We assessed 1,086 consecutive patients with suspected CAD by coronary angiography. We defined severe CAD as Gensini scores > 20. Multiple logistic regression analysis was adjusted for age, sex, hypertension, diabetes mellitus, smoking status, lipid profiles, and body mass index (BMI) to assess the presence or absence of CAD, multivessel disease, and severe CAD in elderly (age ≥ 60 years) and non-elderly (age < 60 years) patients. Results ELC was a significantly positive determinant of CAD (odds ratio (OR) = 3.074, p < 0.001), multivessel disease (OR = 3.101, p < 0.001), and severe CAD (OR = 2.823, p < 0.001) in all patients. ELC was also a predictor of CAD, multivessel disease, and severe CAD not only in patients aged ≥ 60 years (OR = 3.095, p < 0.001; OR = 3.071, p < 0.001; OR = 2.761, p < 0.001, respectively) but also in those aged < 60 years (OR = 2.749, p = 0.035; OR = 2.634, p = 0.038; OR = 2.766, p = 0.006, respectively). Conclusions ELC was independently associated with the presence of CAD, multivessel disease, and severe CAD in both elderly and non-elderly patients who were assessed by coronary angiography.

RESUMO

OBJECTIVES: Eltrombopag, a thrombopoietin-receptor agonist, stimulates hematopoiesis in patients with acquired aplastic anemia (AA). Cytomorphologic changes in bone marrow after eltrombopag administration are still unclear. This study examined the effect of eltrombopag on cytomorphologic findings using data from prior phase 2 studies (E1201 and E1202). METHODS: Microscopic examinations were performed in 31 patients with AA (E1201 [n = 21], E1202 [n = 10]). The relationship between hematologic improvement and morphologic findings was also investigated. RESULTS: In 5 patients (E1201 [n = 3], E1202 [n = 2]), the bone marrow blast count increased after initiation of eltrombopag treatment compared with screening values. The blast count was less than 5%, and the increase in bone marrow blasts was transient in all 4 patients who had bone marrow examinations at follow-up. In 8 patients (E1201 [n = 5], E1202 [n = 3]), dysplastic forms of megakaryocytes were found in the bone marrow following treatment initiation. Dysmegakaryopoiesis of 10% or more was found in 3 patients. None of the patients revealed micromegakaryocytes. Ten patients showed an increase in bone marrow blasts and/or dysmegakaryopoiesis following treatment initiation. Nine of 10 patients showed hematologic improvement in 1 or more lineages. CONCLUSIONS: Dysmegakaryopoiesis without micromegakaryocytes and a transient increase of less than 5% in bone marrow blast count may be signs of hematologic improvement with eltrombopag for patients with AA.

RESUMO

This multicenter, prospective phase IIb trial evaluating the efficacy and safety of tucidinostat (HBI-8000) in patients with relapsed or refractory (R/R) adult T-cell leukemia/lymphoma (ATLL) was undertaken in Japan. Eligible patients had R/R ATLL and had failed standard of care treatment with chemotherapy and with mogamulizumab. Twenty-three patients received tucidinostat 40 mg orally twice per week and were included in efficacy and safety analyses. The primary end-point was objective response rate (ORR) assessed by an independent committee. The ORR was 30.4% (95% confidence interval [CI], 13.2, 52.9]. Median progression-free survival was 1.7 months (95% CI, 0.8, 7.4), median duration of response was 9.2 months (95% CI, 2.6, not reached), and median overall survival was 7.9 months (95% CI, 2.3, 18.0). All patients experienced adverse events (AEs), which were predominantly hematologic and gastrointestinal. Incidence of grade 3 or higher AEs was 78.3%; most were laboratory abnormalities (decreases in platelets, neutrophils, white blood cells, and hemoglobin). Tucidinostat was well tolerated with AEs that could be mostly managed with supportive care and dose modifications. Tucidinostat is a meaningful treatment option for R/R ATLL patients; further investigation is warranted.

RESUMO

BACKGROUND: We report a rare case of left ventricular inflow obstruction from a branch of the left circumflex coronary artery to the right atrium caused by a coronary arteriovenous fistula (CAVF) in a young Japanese male child. CASE PRESENTATION: The patient was diagnosed with CAVF following a heart murmur shortly after birth. The left-to-right shunt caused right ventricular volume overload and pulmonary congestion. An emergency surgical intervention was performed for the CAVF on day 6 after birth. However, by 5 years of age, his left ventricular inflow obstruction worsened. We found an abnormal blood vessel originating from the proximal part of a branch of the left circumflex coronary artery, circling the outside of the mitral valve annulus along the medial side of the coronary sinus. As the child gets older, the blood inflow into the left ventricle might get restricted further, resulting in left-sided heart failure. CONCLUSION: Our findings suggest that even after CAVF closure surgery, it is essential to monitor for complications caused by progressive dilatation of a persistent CAVF.

RESUMO

BACKGROUND: Total anomalous pulmonary venous connection (TAPVC) is a critical congenital heart disease for which emergency surgery is required after birth. In cases of no intervention, TAPVC is associated with a high mortality rate in the first year of life. Although foetal echocardiographic techniques for diagnosing TAPVC have improved, TAPVC remains one of the most difficult congenital heart diseases to diagnose via foetal echocardiography. Here, we report a case of TAPVC with pulmonary venous obstruction (PVO), which was diagnosed via foetal echocardiography. Case Presentation. On foetal echocardiography at 32 weeks' gestation, a large atrial septal defect, enlarged superior vena cava, and continuous flow pattern in the vertical vein from the common chamber were observed in the foetus. Paediatric cardiologists and cardiac surgeons, neonatologists, and obstetricians planned to perform a caesarean section and emergency heart surgery. The male infant was born at 37 weeks' gestation via caesarean section, and postnatal echocardiography revealed PVO at the confluence of the superior vena cava and common chamber. Similarly, chest computed tomography confirmed the foetal diagnosis. The postnatal diagnoses were TAPVC type Ib, PVO, atrial septal defect, and patent ductus arteriosus. Surgical repair of the TAPVC was initiated within the first 3 hours of life. Screening brain echocardiography and head computed tomography revealed intracranial haemorrhage and hydrocephalus. Therefore, the patient underwent emergency bilateral external drainage on day 13. On day 48, a ventriculoperitoneal shunt was inserted owing to progressive brain ventricular dilatation. The patient was discharged home on postoperative day 68. CONCLUSIONS: Although the prognosis of TAPVC with PVO remains poor, continuous observation through foetal echocardiography and early interdepartmental collaboration can result in good outcomes.

RESUMO

Childhood obstructive sleep apnoea syndrome (OSAS) secondary to adenoid hyperplasia is known to give rise to pulmonary hypertension. However, we present a case of a toddler with pulmonary hypertension (PH) and right heart failure due to OSAS, the cause of which is difficult to identify. After the patient underwent an adenotonsillectomy, OSAS disappeared and the PH eventually resolved. Both paediatricians and otolaryngologists should know that paediatric OSAS can occur even in the setting of mild, clinically insignificant palatine tonsil hypertrophy and adenoid hyperplasia. Surgical intervention should be considered without losing the opportunity if it could be the cause of PH.

RESUMO

BACKGROUND: Retroaortic innominate vein is a rare anomaly. It has been reported in patients with congenital anomalies such as Tetralogy of Fallot or right aortic arch. However, isolated retroaortic innominate vein is quite rare. CASE PRESENTATION: A 63-year-old man was transferred to our institution because of Stanford type A acute aortic dissection. Incidentally, we noticed that the left innominate vein coursed under the aortic arch and was directed into the superior vena cava on computed tomography. We performed emergent hemiarch replacement. CONCLUSIONS: Attention must be paid to the cannulation site for venous uptake and the method of myocardial protection.

RESUMO

BACKGROUND: Coronary involvement is rare but can be critical in patients with aortitis. Although cardiac ischemia can be resolved by coronary artery bypass grafting (CABG), patients complicated with cardiac ischemia, calcified aorta, and valve insufficiency pose difficult problems for surgeons. CASE PRESENTATION: A 71-year-old woman was referred to our institution because of unstable angina. She had been previously diagnosed with aortitis and left subclavian artery occlusion. Contrast-enhanced computed tomography revealed severe left coronary main trunk stenosis, right coronary artery occlusion, and porcelain aorta. Ultrasonic echocardiogram showed severe aortic regurgitation. We performed emergent coronary artery bypass grafting, aortic valve replacement and ascending aorta replacement under hypothermic circulatory arrest. CONCLUSIONS: The technique of circumferential calcified intimal removal and reinforcement with felt strips was effective for secure anastomosis. Unilateral cerebral perfusion from the right subclavian artery enabled good visualization and sufficient time to perform distal anastomosis.

RESUMO

Lenalidomide (Len) and dexamethasone (dex) therapy is a standard therapy in patients with multiple myeloma. Elderly or unfit patients may reduce Len or dex doses to prevent toxicities that lead to treatment discontinuation. However, there have been few studies evaluating the efficacy and safety of lower doses of Len and dex. We conducted a phase II study of 1.5-year low-dose Len and dex therapy following melphalan and prednisolone (MP), the number of which cycles was determined by a response within 9 cycles. The Len dose was 10 mg daily and the dex dose was 20 mg weekly, which were continued for 1.5 years. Twenty-one patients were enrolled. The median number of cycles of MP was 3 (range, 2-9). The overall response rate was 81% and a very good partial response or better was achieved in 33.3% of patients. The median follow-up time for survivors was 70.5 months (range, 42-83 months), the median progression-free survival (PFS) was 27 months (95% CI, 21-33 months), and the median overall survival was not reached. Grade 3 or 4 adverse events were observed in 28.6% of patients. In conclusion, the low-dose Len and dex therapy safely achieved comparable efficacies to the standard-dose regimen in elderly patients with newly diagnosed multiple myeloma. UMIN000007889.

RESUMO

The surgical management for type A acute aortic dissection complicated with carotid artery occlusion remains controversial. Between December 2012 and June 2017, 127 patients who presented with type A acute aortic dissection were operated on in our hospital. Of this group, nine (7.08%) patients had cerebral malperfusion due to carotid artery occlusion. The site of occlusion was innominate artery (n = 5) or right carotid artery (n = 4). Preoperative neurological symptoms were left hemiplegia (n = 1), left hemiparesis (n = 3) and seizure (n = 2). Preoperative consciousness level was Japan Coma Scale 2 (n = 6), 20 (n = 2), or 200 (n = 1). The procedure consisted of hemiarch replacement (n = 4) or total arch replacement (n = 5). Aorto-carotid bypass was performed in all patients under hypothermic circulatory arrest. The time from onset of symptoms to operating room was 7.2 ± 2.4 h. Hospital mortality was 0%. Left hemiplegia and left hemiparesis improved significantly. Japan Coma Scale was 0 in all patients at discharge. Overall survival at 24 months after operation was 100%. Aorto-carotid artery bypass for type A acute aortic dissection with carotid artery occlusion is the treatment of choice in these high-risk patients. Our strategy of 'no touch until circulatory arrest' may contribute to neurological improvement.

RESUMO

A 72-year-old man was referred to our institution because of an arch aneurysm and acute aortic dissection (thrombosed Stanford type A). Anti-impulse therapy was initiated. He developed a high fever after admission. Blood culture was negative. Five days after admission, he developed back pain. Thoracoabdominal computed tomography revealed a new low-density area from the distal arch to the descending aorta. We performed emergent total arch replacement. Although we discontinued all sedative drugs after surgery, coma continued. Brain magnetic resonance imaging with diffusion-weighted imaging revealed ventriculitis with brain infarction. After antimicrobial therapy was started, his consciousness level improved. Ventriculitis should be suspected when disturbance of consciousness continues longer than we predict after emergent arch aneurysm surgery. Delay in diagnosis can lead to a life-threatening condition.

RESUMO

Congenital heart disease-associated pulmonary arterial hypertension (CHD-PAH) is one of the major complications in patients with CHD. A timely closure of the left-to-right shunt will generally result in the normalization of the pulmonary hemodynamics, but a few patients have severe prognosis in their early childhood. We hypothesized that wide-ranging pathological mechanism in PAH could elucidate the clinical state of severe CHD-PAH. Using electronic medical records, we retrospectively analyzed six infants with severe CHD-PAH who had treatment-resistant PH. All patients were born with congenital malformation syndrome. After starting on a pulmonary vasodilator, five of the six patients developed complications including pulmonary edema and interstitial lung disease (ILD), and four patients had alveolar hemorrhage. After steroid therapy, the clinical condition improved in four patients, but two patients died. The autopsy findings in one of the deceased patients indicated the presence of recurrent alveolar hemorrhage, pulmonary venous hypertension, ILD, and PAH. Based on the clinical course of these CHD-PAH in patients and the literature, CHD-PAH can occur with pulmonary vascular obstructive disease (PVOD)/pulmonary capillary hemangiomatosis (PCH), ILD, and/or alveolar hemorrhage. The severity of CHD-PAH may depend on a genetic disorder, respiratory infection, and upper airway stenosis. Additionally, pulmonary vasodilators may be involved in the development of PVOD/PCH and ILD. When patients with CHD-PAH show unexpected deterioration, clinicians should consider complications associated with PVOD/PCH and/or pulmonary disease. In addition, the choice of upfront combination therapy for pediatric patients with CHD-PAH should be selected carefully.

RESUMO

Recent reports suggested that cardiopulmonary bypass (CPB) time is one of the risk factors for postoperative complications after Fontan conversion. Although Fontan conversion may be performed for the patients with hepatic fibrosis after initial Fontan procedure, there is no predictive indicator regarding the liver function associated with hemostasis which can affects CPB time. Thirty-one patients who underwent Fontan conversion using the same surgical procedure (extracardiac conduit conversion with right atrium exclusion) were enrolled. In multivariate analyses including age at Fontan conversion, interval from initial Fontan to conversion, hemodynamic data such as right atrial pressure, ventricular end-diastolic pressure, and cardiac index, hepatic data such as platelet count, prothrombin time international normalized ratios, serum total bilirubin, hyaluronic acid levels, five known indices for hepatic fibrosis (Forns Index, APRI, FIB4, FibroIndex, and MELD-XI), and liver stiffness measured by ultrasound elastography, only the Forns Index remained independently associated with the CPB time (P < 0.01) and blood transfusions (plasma transfusions and platelet concentrations: P < 0.01 for both). The cutoff level for Forns Index to predict the prolonged CPB time (exceeding 240 min) was 4.85 by receiver-operating characteristic curve (area under the curve 0.823, sensitivity 76.9%, and specificity 72.2%). Three patients with Forns Index > 7.0 had poor outcomes with long CPB time and massive blood transfusions in contrast with the other 28 patients. In conclusion, Forns Index could serve as a practical predictor of CPB time and is associated with blood transfusion volume in Fontan conversion.

RESUMO

Caldera-forming eruptions of mushy silicic magma are among the most catastrophic natural events on Earth. In such magmas, crystals form an interlocking framework when their content reaches critical thresholds, resulting in the dramatic increase in viscous resistance to flow. Here, we propose a new mechanism for the ascent of mushy magma based on microstructural observations of crystal-rich silicic pumices and lavas from the Central Andes and decompression experiments. Microstructural data include spherical vesicles and jigsaw-puzzle association of broken crystals in pumices, whereas there is limited breakage of crystals in lavas. These observations insinuate that shearing of magma during ascent was limited. Decompression experiments reveal contrasting interaction between growing gas bubbles and the crystal framework in crystal-rich magma. Under slow decompression typical of effusive eruptions, gas extraction is promoted, whereas under rapid decompression, bubbles are retained and the crystal framework collapses. This feedback between decompression rate, retention of gas bubbles, and integrity of the crystal framework leads to strong non-linearity between magma decompression rate and eruption explosivity. We extend these findings to caldera-forming eruptions of crystal-rich magma where large overpressures are induced by caldera-collapse, resulting in magma plug-flow, rapid decompression facilitated by shear-localization at conduit margins, and explosive eruption.

RESUMO

PRéCIS:: A positive correlation was observed between intraocular pressure (IOP) and central venous pressure (CVP) in patients with single ventricle (SV) during the perioperative period. IOP needs to be carefully monitored in the postoperative period after the Glenn and Fontan procedures, particularly the Glenn procedure. PURPOSE: SV is a cardiac malformation characterized by the existence of only 1 functional ventricle and is treated using the Glenn and Fontan procedures. Significant changes occur in CVP after these procedures. IOP has been reported to differ in the same individual when measured in a seated or supine position, which may be related to CVP. In the present study, we examined the relationship between CVP and IOP before and after surgery for SV. PATIENTS AND METHODS: This study was a prospective, nonrandomized case series. All patients had SV and this study excluded those with eye diseases associated with ocular hypertension. We measured IOP before and after the Glenn or Fontan procedure. CVP was concurrently monitored. RESULTS: Twenty-eight eyes of 14 patients with SV who underwent the Glenn (N=8) or Fontan (N=6) procedure were examined. Mean ages (±SD) were 2.6±0.7 months for the Glenn procedure and 24.0±2.7 months for the Fontan procedure. A correlation was observed between CVP and IOP in the perioperative period. IOP and CVP were both significantly higher after than before the Glenn and/or Fontan procedures. However, no relationship was noted between changes in IOP and CVP after the Glenn and/or Fontan procedures. CONCLUSIONS: Elevations in CVP significantly increased IOP in patients with SV who underwent the Glenn or Fontan procedure. IOP needs to be carefully monitored in the postoperative period after both procedures.

RESUMO

An 88-year-old woman with a history of meningioma and dementia was admitted with high fever, loss of appetite, and nausea in July. Urinary tract infection was suspected. Computed tomography (CT) showed no significant findings. Urinary findings improved with administration of ceftriaxone. However, high fever appeared on hospital day 28, and CT identified a gallbladder stone without any abdominal symptoms. We considered the possibility of ceftriaxone-associated pseudolithiasis and changed pharmacotherapy to cefmetazole. CT on day 34 showed a reduction in the size of the gallbladder stone. Ceftriaxone-associated pseudolithiasis might arise in the absence of abdominal symptoms, and clinicians should take the patient background and season into account when using this agent.
