An association has been reported between rotator cuff tear and inflammation. We hypothesized that blood flow in the anterior humeral circumflex artery would reflect synovial inflammation in the ...shoulder. This study aimed to clarify the association of blood flow in the anterior humeral circumflex artery with synovial inflammation and shoulder pain in patients with rotator cuff tears.
In this prospective, cross-sectional study, tissue samples from the synovium in the rotator interval were obtained from 33 patients undergoing arthroscopic rotator cuff repair. Reverse transcription-polymerase chain reaction and real-time polymerase chain reaction were performed to determine the messenger RNA expression of inflammatory mediators, growth factors, and matrix metalloproteinases. Additional tissue samples were fixed for histologic evaluation. Before surgery, we measured the peak systolic velocity in the anterior humeral circumflex artery using pulse Doppler ultrasonography.
The peak systolic velocity in the anterior humeral circumflex artery was positively correlated with the messenger RNA expression of interleukin 1β, interleukin 8, and matrix metalloproteinase 3 genes (r = 0.49, P = .004; r = 0.55, P = .001; and r = 0.39, P = .026, respectively), as well as histologic synovitis scores (r = 0.48, P = .005). Additionally, it was significantly higher in patients with resting pain than in those without resting pain (P = .048).
The peak systolic velocity in the anterior humeral circumflex artery is associated with the severity of synovial inflammation. Our results suggest that assessing the peak systolic velocity in the anterior humeral circumflex artery is useful for evaluating the severity of synovial inflammation.
Abstract Background The effects of the combination of angiotensin II receptor blocker (ARB) plus dihydropyridine calcium channel blockers (DHP-CCBs), which is known as a potent antihypertensive drug ...regimen, on cardiovascular events remain unclear. Objective The purpose of this post hoc subgroup analysis was to compare the incidence of major adverse cardiovascular events (MACE) of patients treated with candesartan and amlodipine with that of those with candesartan and non-amlodipine CCBs in hypertensive patients with coronary artery disease (CAD). Methods HIJ-CREATE was a multicenter, prospective, randomized, controlled study that compared the effects of candesartan-based with those of non-ARB-based standard therapy on MACE in 2049 hypertensive patients with CAD. In the candesartan group, a total of 335 patients were treated with DHP-CCBs (amlodipine: 170 and non-amlodipine-CCBs: 165) at the baseline. In this sub-analysis, we compared, among the participants allocated to candesartan regimen, the long-term effects of amlodipine and non-amlodipine CCBs that were concomitantly given with ARB, although the choice of CCB was not randomized. Results The median follow-up was 3.9 years. Treatment using amlodipine with candesartan reduced the risk of MACE by 38% (hazard ratio, 0.62; 95% confidence interval, 0.41–0.94, p = 0.025), as compared to patients treated with non-amlodipine-CCBs and candesartan. In a multivariate analysis, combination therapy of candesartan with amlodipine was an independent predictor of reduced risk of MACE. Conclusions The results suggest that the combination of amlodipine and candesartan is more beneficial in reducing MACE in hypertensive patients with CAD compared to non-amlodipine-DHP-CCBs in combination therapy with candesartan. Further investigation in larger-scale prospective randomized studies is required to reach any conclusion as to the superiority of combination therapy of candesartan with amlodipine.
Background Adherence to self-care behavior is important for patients with heart failure (HF) to prevent exacerbation of HF. The aim of this study was to evaluate adherence, identify associated ...factors, and clarify the impact of previous HF hospitalizations on adherence in outpatients with HF. Methods A total of 116 outpatients completed a questionnaire, including the Japanese version of the European Heart Failure Self-Care Behavior Scale, to assess adherence. Results Regardless of previous hospitalizations, adherence to seek help if HF worsened was poor. Multivariate analysis adjusted for age and brain natriuretic peptide showed that diabetes mellitus and being employed were independent predictors of poorer adherence to self-care behavior ( P = .03, P = .02, respectively), but the experience of previous HF hospitalizations was not a predictor. Conclusions Self-care strategies for HF should target patients with diabetes mellitus and employed patients. Further study is necessary to develop effective programs for such patients.
Epithelioid hemangioendothelioma (EHE) is a rare neoplasm originating from various organs. The clinical outcome mostly depends on surgical resectability. The authors report an EHE of the extracranial ...internal carotid artery developed in a 59-year-old male patient 14 years after the intravascular coil embolization for a carotid aneurysm at the same site. Because the lesion was initially diagnosed as regrowth of the thrombosed aneurysm, decision for radical resection was delayed, and the patient died from rapid tumor progression. Differential diagnosis of atypical vascular mass lesions should include neoplasm, because initial radical resection may be the key to achieve a better prognosis.
Adrenocortical carcinoma (ACC) is a rare malignant tumor with a poor prognosis. Local recurrence or distant metastases occur in more than 50% of cases. Patients with metastases have limited treatment ...options, and <15% have a 5-year survival time. Herein, we describe a 44-year-old woman with ACC and who underwent retroperitoneal tumor resection. Multiple liver and lung metastases were found 1-year postresection. Mitotane therapy started as systemic treatment. Lung metastases were controlled but liver metastases were progressive. The liver metastases were treated by performing 2 resections and 6 bland transarterial embolization (bland TAE), and are presently controlled with only 2 liver metastases of <20 mm. The present case showed that bland TAE can achieve long-term prevention of the progression of liver metastases of ACC. The ultraselective bland TAE for selective embolization supported by the latest computed tomography analysis techniques during arteriography could minimize liver damage caused by embolization and allowed multiple treatments which prolonged survival. We conclude that bland TAE can be effective for controlling liver metastases of ACC.
Background There are contradictory reports on outcomes of patients treated for Stanford type A acute intramural hematoma (IMH) and acute aortic dissections (AAD) with thrombosed false lumens. We ...evaluated short-term clinical outcomes and predictors of adverse outcomes. Methods We retrospectively analyzed 59 symptomatic patients with type A acute IMH and AAD with thrombosed thoracic false lumens who initially received treatment. Survival, aortic death (death from aortic events and sudden deaths), and aortic event-free survival rates were investigated. False lumen thickness ratios (FTR false lumen thickness/aortic diameter) were measured by computed tomography scan and the relationship with aortic events was evaluated. Results Survival, aortic death-free survival, and aortic event-free survival rates at 2 years were 90.0%, 96.6%, and 55.8%, respectively. Ascending aortic diameters, false lumen thickness of the ascending aortas, and rate of penetrating aortic ulcers in the ascending aortas were higher among patients with aortic events. The FTR of the ascending aorta (FTRA)/FTR of the descending aorta (FTRD) was also higher in these patients (1.3 ± 0.9 versus 0.8 ± 0.5, p = 0.0021). Multivariate analysis revealed FTRA/FTRD greater than 0.98 (odds ratio 5.35; 95% confidence interval: 0.05 to 1.72; p = 0.0431) as an independent predictor of aortic events. An FTRA/FTRD greater than 0.98 predicted aortic events with 87.1% sensitivity and 58.4% specificity. Conclusions High aortic event rates were seen after treatment for type A acute IMH and AAD with thrombosed thoracic false lumens. Nevertheless, short-term survival rates were favorable. An FTRA/FTRD greater than 0.98 may be a highly sensitive predictor for aortic events.
Abstract Objectives This study sought to demonstrate the prevalence, mechanism, and electrocardiographic and electrophysiological characteristics of upper septal idiopathic left fascicular ...ventricular tachycardia (US-ILVT). Background ILVT is classified into left anterior and posterior types with no clear data about US-ILVT. Methods Among 193 ILVT patients, we identified 12 patients (6.2%; age 41 ± 22 years, 7 men) with US-ILVT. Results Of 12 patients with US-ILVT, 6 patients (50%) had previous history of radiofrequency catheter ablation for common ILVT. Sustained VT (cycle length: 349 ± 53 ms) was seen in all patients with a QRS interval slightly wider (104 ± 18 ms) than that during sinus rhythm (90 ± 19 ms). The VT exhibited an identical QRS configuration as sinus rhythm in 6 (50%) and incomplete right bundle branch block configuration in another 6. His-ventricular interval during VT was always shorter than that during sinus rhythm (27 ± 5 ms vs. 47 ± 10 ms). Purkinje potentials were activated in a reverse direction to that of common ILVT; namely, the diastolic potential (P1 ) was activated retrogradely but the pre-systolic potential (P2 ) was activated antegradely. At the left upper-middle ventricular septum, P1 potential was recorded during VT, preceding the QRS by 54 ± 20 ms. Radiofrequency catheter ablation at that site eliminated the VT with no recurrence during a 58 ± 35 months of follow-up. Conclusions US-ILVT is an identifiable VT that shares common criteria with ILVT and has a narrow QRS interval. Some US-ILVT cases appeared after common ILVT ablation. It is a reverse type of common ILVT (orthodromic form) with baseline morphological abnormalities that might provide a potential substrate for such VT.
