Ultrasound-guided percutaneous injection to treat de Quervain's disease using three different techniques: a randomized controlled trial.

PURPOSE: To compare the six-month outcome of three different ultrasound-guided treatments for de Quervain's disease (DQD). METHODS: We prospectively treated 75 consecutive patients (51 females, 24 males, mean age ± standard deviation = 45.3 ± 9.8 years) with DQD. Patients' features (hand dominance, intraretinaculum septum, accessory tendons) were recorded. Visual analogue scale (VAS), reduced disability (quickDASH) score, and retinaculum thickness were evaluated at baseline and after one (excluding retinaculum thickness), three, and six months. Patients were randomized into three groups of 25 patients each treated under ultrasound guidance: Group A (1 ml methylprednisolone acetate; mean baseline thickness = 1.6 mm; mean baseline VAS = 6; mean baseline quickDASH = 55); Group B (1 ml methylprednisolone acetate +15-day delayed 2 ml saline 0.9 %; 1.4; 6; 56); Group C (1 ml methylprednisolone acetate +15-day delayed 2 ml low molecular weight hyaluronic acid; 1.7; 6; 55). RESULTS: After one month results were: Group A mean VAS = 2; mean quickDASH = 23; Group B 2; 22; Group C 2; 21. After three months results were: Group A retinaculum thickness = 0.7 mm; 3; 27); Group B 0.8 mm; 1; 25; Group C 0.5 mm; 1; 23. After six months results were: Group A 1.5 mm; 3; 51; Group B 1 mm; 2; 51; Group C 0.7 mm; 1; 26 (P < 0.001 for all vs. baseline). Patients' age, sex, hand dominance, presence of subcompartment dividing septum, and supernumerary tendons had no influence on outcome (P ≥ 0.177). CONCLUSION: Addition of hyaluronic acid to ultrasound-guided injections of steroids to treat DQD seems to improve the outcome and to reduce the recurrence rate. KEY POINTS: • Ultrasound guidance allows for safe injection procedures to treat de Quervains' disease • Steroid injections allow prompt recovery in de Quervain's disease with short-term recurrence • Addition of hyaluronic acid allows recurrence rate reduction compared to simple steroid injections.

Appearance of hepatocellular carcinoma on gadoxetic acid-enhanced hepato-biliary phase MR imaging: a systematic review.

OBJECTIVE: To perform a systematic review of the contrast behaviour of HCC on Gd-EOB-DTPA hepato-biliary phase MRI. MATERIALS AND METHODS: This review was completed in accordance with the recommendations outlined in the preferred reporting items for systematic reviews statement. In all reports, qualitative analysis of signal intensity (SI) of HCC on hepato-biliary phase was performed: the relative SI of HCC. When available, a quantitative analysis of tumour enhancement was evaluated. RESULTS: A total of 106 studies were retrieved, of which 41 met the inclusion criteria. The total number of patients was 2550, with 3132 HCC. MRI showed 3110 HCC (22 non-detected). 2692/3110 (87 %) HCC were hypointense on Gd-EOB-DTPA-enhanced hepatocyte-phase MRI, 134 (4 %) isointense; 106 (3 %) hyperintense and 178 (6 %) iso-hyperintense. In 26 articles, 1653 HCCs were classified as follows: 519 well-differentiated, 883 moderately differentiated, 251 poorly differentiated. Among well-differentiated HCC, 445 (86 %) were hypointense, 12 isointense (2 %), 9 hyperintense (2 %), 53 iso/hyperintense (10 %). Among moderately differentiated HCC, 774 (88 %) were hypointense, 8 isointense (1 %), 27 hyperintense (3 %), 74 iso/hyperintense (8 %). Among poorly differentiated HCCs, 245 (98 %) were hypointense, one isointense, one hyperintense and four iso-hyperintense (2 %). We found a Chi-square (χ (2)) equivalent to 25,082 (p < 0.001). CONCLUSION: The percentage of lesions iso/hyper/iso-hyper is the same when considering well-differentiated and moderately differentiated HCC; when considering poorly differentiated HCC, the percentage of lesions iso/hyper/iso-hyper is significantly lower. Conversely, the percentage of lesions hypointense is significantly more represented in poorly differentiated HCC compared to well-differentiated and moderately differentiated HCC.

Severe aortic stenosis and transcatheter aortic valve replacement in elderly patients: utility vs. futility.

Recently, transcatheter aortic valve replacement (TAVR) has emerged as established standard treatment for symptomatic severe aortic stenosis, providing an effective, less-invasive alternative to open cardiac surgery for inoperable or high-risk older patients. In order to assess the anticipated benefit of aortic replacement, considerable interest now lies in better identifying factors likely to predict outcome. In the elderly population frailty and medical comorbidities have been shown to significantly predict mortality, functional recovery and quality of life after transcatheter aortic valve replacement. Scientific literature focused on the three items will be discussed. High likelihood of futility is described in patients with severe chronic lung, kidney, liver disease and/or frailty. The addition of frailty components to conventional risk prediction has been shown to result in improved discrimination for death and disability following the procedure and identifies those individuals least likely to derive benefit. Several dedicated risk score have been proposed to provide new insights into predicted "futile" outcome. However, assessment of frailty according to a limited number of variables is not sufficient, while a multi-dimensional geriatric assessment significantly improves risk prediction. A multidisciplinary heart team that includes geriatricians can allow the customization of therapeutic interventions in elderly patients to optimise care and avoid futility.

Outcomes of single­lead VDD pacemakers in atrioventricular blocks: The OSCAR study.

BACKGROUND: VDD pacemakers are regarded as a second choice in patients with atrio-ventricular blocks mainly due to the potential failure of atrial sensing, leading to a loss of atrio-ventricular synchrony. This single-centre study aimed to evaluate the prevalence of loss of atrial sensing and its potential determinants in patients with VDD pacemakers. METHOD: 142 patients with an implanted VDD device underwent long-term follow-up with clinical evaluation, electrocardiogram, device interrogation and echocardiogram. RESULTS: Over a long follow-up period [median 110 (68-156) months], 17 patients (12%) in sinus rhythm presented loss of atrial sensing. This was most often intermittent, but three patients required a permanent switch to VVI mode. ECG showed higher prevalence of interatrial blocks (50% vs 26.6%, p = 0.057) and longer P wave duration (116 ± 19 vs 105 ± 15 ms, p = 0.019) in patients with loss of atrial sensing. Echocardiography revealed larger left atrial (LA) volumes (p < 0.05) in patients with loss of atrial sensing, and lower LA ejection fraction (0.40 vs 0.47, p = 0.0037) and expansion index (0.63 ± 0.26 vs 0.90 ± 0.31, p = 0.003). P wave duration on ECG proved to be independently associated with loss of atrial sensing on multivariable analysis (OR 1.062, 95% CI 1.015-1.110; p = 0.008). The prevalence of atrial fibrillation and subsequent switch to VVI mode was high (16%). CONCLUSIONS: In the long-term follow-up, the loss of atrial sensing is present in 12% of patients with implanted VDD pacemakers. ECG and echocardiographic parameters may serve as screening tools for the detection of atrial myopathy which is associated with the loss of atrial sensing.

Computerized tomographic assessment and clinical evaluation in shoulder instability treated with the Latarjet-Patte procedure using one screw and washer.

BACKGROUND: The Latarjet-Patte (L-P) procedure is indicated in anterior instability of the shoulder with a glenoid or humeral bone loss. Our purpose is to evaluate clinical outcome and computerized tomographic (CT) findings as position and resorption of the graft and articular degeneration. METHODS: From 2006 to 2009 50 patients underwent to L-P, 48 was contacted by telephone and 26 were available for follow-up (3 to 6 years). Quick-DASH and Rowe scores was used, 22 patients perform CT. RESULTS: None of contacted patients reported a new dislocation. The clinical outcome in the 26 followed patients was excellent: mean Quick DASH score: 1.9; mean ROWE score was 94.7. CT scans showed no evidence of articular degeneration of humeral head. There was partial resorption of the graft in 13 patients. We found a correlation between the zone of partial resorption and position of the graft. CONCLUSIONS: CT scan is appropriate to study position and the healing of coracoid graft. A correct choice of where to place the graft together with a wide bone contact and stable synthesis does not cause degenerative changes after 6 years in our series. LEVEL OF THE EVIDENCE: IV.

Helicobacter pylori active infection in patients with acute coronary heart disease.

OBJECTIVES: To evaluate the possible role of the active Helicobacter pylori infection as a trigger factor in acute coronary heart disease (CHD). METHODS: Forty patients with acute coronary syndromes, 40 patients with infections other than H. pylori (control group A) and 40 healthy subjects (control group B), pair matched for age, sex and CHD risk factors were studied. In each patient and control subject the presence of H. pylori stool antigen (HpsA) and serum anti-CagA were tested. RESULTS: Twenty-eight of patients with CHD resulted positive for HpSA compared to 14 patients of control group A and 16 subjects of group B (p=0.00095). No significant difference was found in the anti-CagA positivity among patients with CHD and control groups. Concomitant positivity for anti-CagA and HpSA was found in 13 patients with CHD, four controls of group A and five controls of group B (p=0.017) CONCLUSIONS: Our findings revealed a higher rate of HpSA positivity and a significantly higher association between HpSA and anti-CagA positivity in patients with acute CHD compared to control groups. These data suggest that active H. pylori infection may play a role as a trigger factor in acute cardiovascular events.

Coronary collateral for left anterior descending coronary artery from a developed right ventricular branch arising from the right sinus of Valsalva.

A 65-year-old man with stable angina refractory to medical therapy and with a low-threshold myocardial ischemia at ECG stress testing was referred for coronary angiography. The coronary angiogram showed an ostial subocclusive stenosis of a developed first diagonal branch located just upstream of a subocclusive stenosis of the mid left anterior descending (LAD) coronary artery, occluded distally, and a coronary collateral for LAD from a developed right ventricular branch arising with separate ostia from the right sinus of Valsalva. We discuss the diagnostic interpretation of this coronary anomaly and some aspects regarding the percutaneous treatment of bifurcations.

The management of Takayasu's arteritis: personal experience.

Takayasu's arteritis is a chronic vasculitis mainly involving the aorta and its main branches. Almost all patients have ischemic disorders of the involved vessels. Treatment is nowadays controversial. Relapses are frequent. In the present study, we elucidate the long-term outcomes of our patients with Takayasu's arteritis. Between November 1993 and October 2003, 10 patients with Takayasu's disease were treated. All patients underwent medical treatment (corticosteroid for 7 months, cyclophosphamide for 3 months, and methotrexate for 12 months). Two patients stopped treatment with methotrexate when renal failure occurred. Four patients underwent a surgical procedure. During treatment, erythrocyte sedimentation rate and C-reactive protein concentrations were determined as indexes of inflammatory activity and treatment responsiveness. Four out of eight patients (50%) who underwent the full treatment with methotrexate had no relapse of the disease. The other four patients (50%) had relapse of the disease but had a better response to new corticosteroid treatment. The two patients who stopped methotrexate treatment died from complications of Takayasu's arteritis. In our personal experience, long-term treatment with methotrexate demonstrated a certain efficacy in avoiding relapse, maintaining stability of results, and amplifying the effects of steroid in patients with relapse.
