Treatment of branch retinal vein occlusion induced macular edema with bevacizumab

Branch retinal vein occlusion is a frequent cause of visual loss with currently insufficient treatment options. We evaluate the effect of Bevacizumab (Avastin) treatment in patients with macular edema induced by branch retinal vein occlusion.

[Safety of treatment with tacrolimus ointment for anterior segment inflammatory diseases]

BACKGROUND: The off-label use of topical tacrolimus (Protopic) for inflammatory external eye diseases is gaining popularity. However, there are no reports on the safety profile of this new treatment option. PATIENTS AND METHODS: We treated six patients with different inflammatory eye diseases with topical tacrolimus (Protopic 0.03 %) as off-label use in addition to the conventional anti-inflammatory treatment. Patients were interviewed for side effects and serum drug concentrations were measured under steady state conditions one hour after topical application of tacrolimus ointment. RESULTS: Two patients reported a slight burning sensation immediately after application, in one patient we found a slight worsening of the dry eye problems. No patient abandoned the treatment due to side effects. Serum drug concentrations remained below the analytical threshold in all cases (< 1.5 ng/ml). CONCLUSIONS: Tacrolimus for the topical treatment of anterior segment inflammatory eye diseases is well tolerated without detectable systemic drug resorption.

Surgical versus percutaneous revascularization of coronary artery disease in diabetic patients

Morbidity and mortality related to coronary artery disease (CAD) remain a great challenge in patients with diabetes mellitus. Revascularization of CAD is an important therapeutic intervention owing to its impact on both symptoms and prognosis. The optimal revascularization strategy continues to evolve due to the advent of new technologies and improved peri-procedural outcome with both percutaneous coronary interventions and coronary artery bypass grafting. Although clinical outcome following coronary artery bypass is worse in diabetic as opposed to non-diabetic patients, surgical revascularization tends to be associated with better outcome in stable patients with multivessel disease and reduced left ventricular function. The advent of drug-eluting stents has challenged the supremacy of coronary artery bypass grafting and has become a valuable alternative to surgery. The safety and efficacy of drug-eluting stents in the treatment of patients with diabetes and multivessel disease is currently under investigation in several ongoing randomized controlled trials. Percutaneous coronary intervention is the therapy of choice in patients with acute coronary syndromes, particularly ST-elevation myocardial infarction. The focus of this review is to present the current evidence, define the role of percutaneous and surgical revascularization in the treatment of diabetic patients with CAD, and propose a tailored approach for clinical decision-making.

Three-year cost analysis of function-centred versus pain-centred inpatient rehabilitation in patients with chronic non-specific low back pain

OBJECTIVE: To compare costs of function- and pain-centred inpatient treatment in patients with chronic low back pain over 3 years of follow-up. DESIGN: Cost analysis of a randomized controlled trial. PATIENTS: A total of 174 patients with chronic low back pain were randomized to function- or pain-centred inpatient treatment. METHODS: Data on direct and indirect costs were gathered by questionnaires sent to patients, health insurance providers, employers, and the Swiss Disability Insurance Company. RESULTS: There was a non-significant difference in total medical costs after 3 years' follow-up. Total costs were 77,305 Euros in the function-centred inpatient treatment group and 83,085 Euros in the pain-centred inpatient treatment group. Likewise, indirect costs after 3 years from lost work days were non-significantly lower in the function-centred in-patient treatment group (6354 Euros; 95% confidence interval -20,892, 8392) and direct medical costs were non-significantly higher in the function-centred inpatient treatment group (574 Euros; 95% confidence interval -862, 2011). CONCLUSION: The total costs of function-centred and pain-centred inpatient treatment were similar over the whole 3-year follow-up.

Antiplatelets versus Anticoagulants for the Treatment of Cervical Artery Dissection: Bayesian Meta-Analysis

OBJECTIVE To compare the effects of antiplatelets and anticoagulants on stroke and death in patients with acute cervical artery dissection. DESIGN Systematic review with Bayesian meta-analysis. DATA SOURCES The reviewers searched MEDLINE and EMBASE from inception to November 2012, checked reference lists, and contacted authors. STUDY SELECTION Studies were eligible if they were randomised, quasi-randomised or observational comparisons of antiplatelets and anticoagulants in patients with cervical artery dissection. DATA EXTRACTION Data were extracted by one reviewer and checked by another. Bayesian techniques were used to appropriately account for studies with scarce event data and imbalances in the size of comparison groups. DATA SYNTHESIS Thirty-seven studies (1991 patients) were included. We found no randomised trial. The primary analysis revealed a large treatment effect in favour of antiplatelets for preventing the primary composite outcome of ischaemic stroke, intracranial haemorrhage or death within the first 3 months after treatment initiation (relative risk 0.32, 95% credibility interval 0.12 to 0.63), while the degree of between-study heterogeneity was moderate (τ(2) = 0.18). In an analysis restricted to studies of higher methodological quality, the possible advantage of antiplatelets over anticoagulants was less obvious than in the main analysis (relative risk 0.73, 95% credibility interval 0.17 to 2.30). CONCLUSION In view of these results and the safety advantages, easier usage and lower cost of antiplatelets, we conclude that antiplatelets should be given precedence over anticoagulants as a first line treatment in patients with cervical artery dissection unless results of an adequately powered randomised trial suggest the opposite.

Nonsurgical treatment of aggressive periodontitis with photodynamic therapy or systemic antibiotics. Three-month results of a randomized, prospective, controlled clinical study

The aim of this randomized, controlled clinical study was to compare the short-term effects of nonsurgical periodontal therapy with the additional administration of systemic antibiotics (AB) and the same therapy with additional photodynamic therapy (PDT) in the treatment of patients with aggressive periodontitis (AP). Thirty-six patients with AP received full-mouth nonsurgical periodontal treatment (SRP) and were then randomly divided into two groups of 18 subjects each. Group AB received amoxicillin and metronidazole three times a day for 7 days. Group PDT received two applications of PDT on the day of SRP as well as at follow-up after 7 days. The following clinical parameters were measured at baseline and 3 months after therapy: plaque index (PLI), bleeding on probing (BOP), probing depth (PD), gingival recession (GR), and clinical attachment level (CAL). After 3 months, PD was significantly reduced in both groups (from 5.0±0.8 mm to 3.2±0.4 mm with AB, and 5.1±0.5 mm to 4.0±0.8 mm with PDT; both p<0.001), while AB revealed significantly lower values compared to PDT (p = 0.001). In both groups, GR was not significantly changed. CAL was significantly reduced in both groups (PDT: 5.7±0.8 mm to 4.7±1.1 mm; p=0.011; AB: 5.5±1.1 mm to 3.9±1.0 mm; p<0.001) and differed significantly between the groups (p=0.025). The number of residual pockets (PD ≥4 mm) and positive BOP was reduced by AB from 961 to 377, and by PDT from 628 to 394. Pockets with PD ≥7 mm were reduced by AB from 141 to 7, and by PDT from 137 to 61. After 3 months, both treatments led to statistically significant clinical improvements. The systemic administration of antibiotics, however, resulted in significantly higher reduction of PD and a lower number of deep pockets compared to PDT.

Late recurrent arrhythmias after ablation of atrial fibrillation: incidence, mechanisms, and treatment.

OBJECTIVES The aim of the study was to determine the incidence of atrial flutter and other arrhythmia recurrences (other than atrial fibrillation [AF]) during long-term follow-up after left atrial substrate modification by percutaneous radiofrequency (RF) ablation of AF. BACKGROUND RF ablation is an effective treatment for patients with AF. However, late recurrent arrhythmias may complicate the patient's course. METHODS One hundred fifty consecutive patients with paroxysmal or persistent AF were included in this prospective study. The incidence of arrhythmia recurrences after AF ablation was analyzed during long-term follow-up using repetitive 7-day ECG recording. RESULTS In 28 of 150 patients (18.7%), stable regular arrhythmias other than AF were detected during follow-up. Left atrial flutter observed in 10 patients (6.7%) was treated by recompletion of the ablation lines in all 10 patients. Left atrial flutter was associated with recurrence of AF in all 10 patients. Nine of 10 patients (90%) were free from atrial flutter and 6 of 10 patients were free from AF after the second intervention. Typical right atrial flutter occurred in 10 patients (6.7%) and was treated successfully by percutaneous RF ablation without recurrence in all patients. Additionally, atrial flutter was documented during follow-up in 7 patients (4.7%); however, invasive electrophysiologic evaluation was not performed due to various reasons. CONCLUSIONS Left atrial flutter is a relevant complication after RF catheter ablation of AF and was always associated with AF recurrence in our study population. Prevention of left atrial flutter can be achieved by induction of ablation lines as continuous and transmural as possible. However, left atrial flutter that does occur late after ablation is amenable to interventional treatment with good prospects of success.

Evaluation of histological, serological and clinical changes in response to abatacept treatment of primary Sjögren's syndrome: A pilot study

Objectives To prospectively evaluate histopathologic, blood cellular, serological and clinical changes in response to abatacept treatment in patients with primary Sjögren's syndrome (pSS). Methods Blood, saliva and minor salivary gland biopsies were obtained before and after the last of 8 doses of abatacept in 11 pSS patients. The histologic data evaluated the number of lymphocytic foci and of B- and T-cell subtypes (CD20(+) , CD3(+) , CD4(+) , CD8(+) ). The numbers of FoxP3(+) regulatory T-cells were measured and the FoxP3 /CD 3 ratio was calculated. Histologic data were compared with results from peripheral blood and with changes in saliva secretion. Results The numbers of lymphocytic foci decreased significantly (p=0.041). Numbers of local FoxP3(+) T-cells decreased significantly in percentage of total lymphocytic infiltrates (p=0.037). In the peripheral blood B-cells increased (p=0.038). This was due to an expansion of the naïve B cell pool (p=0.034). When adjusting for disease duration, an increase was also noted for total lymphocytes (p=0.044) and for CD 4 cells (p=0.009). Gamma globulins decreased significantly (p=0.005), but IgG reduction did not reach significance. Adjusted for disease duration, saliva production increased significantly (p=0.029). Conclusions CTLA4-Ig treatment significantly reduces glandular inflammation in pSS, induces several celluar changes and increases saliva production. Remarkably, this increase in saliva production is significantly influenced by disease duration.

Anatomical eligibility of the renal vasculature for catheter-based renal denervation in hypertensive patients.

OBJECTIVES This study sought to determine the vascular anatomical eligibility for catheter-based renal artery denervation (RDN) in hypertensive patients. BACKGROUND Arterial hypertension is the leading cardiovascular risk factor for stroke and mortality globally. Despite substantial advances in drug-based treatment, many patients do not achieve target blood pressure levels. To improve the number of controlled patients, novel procedure- and device-based strategies have been developed. RDN is among the most promising novel techniques. However, there are few data on the vascular anatomical eligibility. METHODS We retrospectively analyzed 941 consecutive hypertensive patients undergoing coronary angiography and selective renal artery angiography between January 1, 2010, and May 31, 2012. Additional renal arteries were divided into 2 groups: hilar (accessory) and polar (aberrant) arteries. Anatomical eligibility for RDN was defined according to the current guidelines: absence of renal artery stenosis, renal artery diameter ≥4 mm, renal artery length ≥20 mm, and only 1 principal renal artery. RESULTS A total of 934 hypertensive patients were evaluable. The prevalence of renal artery stenosis was 10% (n = 90). Of the remaining 844 patients without renal artery stenosis, 727 (86%) had nonresistant hypertension and 117 (14%) had resistant hypertension; 62 (53%) of the resistant hypertensive and 381 (52%) of the nonresistant hypertensive patients were anatomically eligible for sympathetic RDN. CONCLUSIONS The vascular anatomical eligibility criteria of the current guidelines are a major limiting factor for the utilization of RDN as a therapeutic option. Development of new devices and/or techniques may significantly increase the number of candidates for these promising therapeutic options.

EAU guidelines on surgical treatment of urinary incontinence

CONTEXT The European Association of Urology (EAU) guidelines on urinary incontinence published in March 2012 have been rewritten based on an independent systematic review carried out by the EAU guidelines panel using a sustainable methodology. OBJECTIVE We present a short version here of the full guidelines on the surgical treatment of patients with urinary incontinence, with the aim of dissemination to a wider audience. EVIDENCE ACQUISITION Evidence appraisal included a pragmatic review of existing systematic reviews and independent new literature searches based on Population, Intervention, Comparator, Outcome (PICO) questions. The appraisal of papers was carried out by an international panel of experts, who also collaborated in a series of consensus discussions, to develop concise structured evidence summaries and action-based recommendations using a modified Oxford system. EVIDENCE SUMMARY The full version of the guidance is available online (www.uroweb.org/guidelines/online-guidelines/). The guidance includes algorithms that refer the reader back to the supporting evidence and have greater accessibility in daily clinical practice. Two original meta-analyses were carried out specifically for these guidelines and are included in this report. CONCLUSIONS These new guidelines present an up-to-date summary of the available evidence, together with clear clinical algorithms and action-based recommendations based on the best available evidence. Where high-level evidence is lacking, they present a consensus of expert panel opinion.

Risk of Cardiovascular Events and Blood Pressure Control in Hypertensive HIV-Infected Patients: HIV Cohort Study (SHCS)

Background: Prevalence of hypertension in HIV infection is high, and information on blood pressure control in HIV-infected individuals is insufficient. We modeled blood pressure over time and the risk of cardiovascular events in hypertensive HIV-infected individuals. Methods: All patients from the Swiss HIV Cohort Study with confirmed hypertension (systolic or diastolic blood pressure above 139 or 89 mm Hg on 2 consecutive visits and presence of at least 1 additional cardiovascular risk factor) between April 1, 2000 and March 31, 2011 were included. Patients with previous cardiovascular events, already on antihypertensive drugs, and pregnant women were excluded. Change in blood pressure over time was modeled using linear mixed models with repeated measurement. Results: Hypertension was diagnosed in 2595 of 10,361 eligible patients. Of those, 869 initiated antihypertensive treatment. For patients treated for hypertension, we found a mean (95% confidence interval) decrease in systolic and diastolic blood pressure of −0.82 (−1.06 to −0.58) mm Hg and −0.89 (−1.05 to −0.73) mm Hg/yr, respectively. Factors associated with a decline in systolic blood pressure were baseline blood pressure, presence of chronic kidney disease, cardiovascular events, and the typical risk factors for cardiovascular disease. In patients with hypertension, increase in systolic blood pressure [(hazard ratio 1.18 (1.06 to 1.32) per 10 mm Hg increase], total cholesterol, smoking, age, and cumulative exposure to protease inhibitor–based and triple nucleoside regimens were associated with cardiovascular events. Conclusions: Insufficient control of hypertension was associated with increased risk of cardiovascular events indicating the need for improved management of hypertension in HIV-infected individuals.

Effects of Motive-Oriented Therapeutic Relationship in a Ten-Session General Psychiatric Treatment of Borderline Personality Disorder: A Randomized Controlled Trial

Background: Motive-oriented therapeutic relationship (MOTR) was postulated to be a particularly helpful therapeutic ingredient in the early treatment phase of patients with personality disorders, in particular with borderline personality disorder (BPD). The present randomized controlled study using an add-on design is the first study to test this assumption in a 10-session general psychiatric treatment with patients presenting with BPD on symptom reduction and therapeutic alliance. Methods: A total of 85 patients were randomized. They were either allocated to a manual-based short variant of the general psychiatric management (GPM) treatment (in 10 sessions) or to the same treatment where MOTR was deliberately added to the treatment. Treatment attrition and integrity analyses yielded satisfactory results. Results: The results of the intent-to-treat analyses suggested a global efficacy of MOTR, in the sense of an additional reduction of general problems, i.e. symptoms, interpersonal and social problems (F 1, 73 = 7.25, p < 0.05). However, they also showed that MOTR did not yield an additional reduction of specific borderline symptoms. It was also shown that a stronger therapeutic alliance, as assessed by the therapist, developed in MOTR treatments compared to GPM (Z 55 = 0.99, p < 0.04). Conclusions: These results suggest that adding MOTR to psychiatric and psychotherapeutic treatments of BPD is promising. Moreover, the findings shed additional light on the perspective of shortening treatments for patients presenting with BPD.

Efficacy and Safety of Natalizumab in Crohn’s Disease Patients Treated at 6 Boston Academic Hospitals

BACKGROUND: Despite trials demonstrating its efficacy, many physicians harbor concerns regarding the use of natalizumab in the treatment of patients with refractory Crohn's disease (CD). The purpose of this study was to perform a descriptive analysis of a series of CD patients not currently enrolled in a clinical trial. METHODS: A retrospective case review of patients treated with natalizumab at 6 sites in Massachusetts: Boston Medical Center, Beth Israel Deaconess Medical Center, Brigham & Women's Hospital, Lahey Clinic, Massachusetts General Hospital, and UMass Medical Center. RESULTS: Data on 69 CD patients on natalizumab were collected. At the start of treatment, patients' disease duration was 12 years. A high proportion of patients were women (68%), presented with perianal disease (65%) and upper gastrointestinal tract involvement (14%). Prior nonbiologic therapies were steroids (96%), thiopurines (94%), antibiotics (74%), methotrexate (58%), and at least two anti-tumor necrosis factor agent failures (81%). Sixty-nine percent (44 of 64 patients) with available medical evaluation had a partial or complete clinical response. Loss of response was 13% after an average of 1 year of treatment. Adverse events were infusion reactions, headaches, fever, and infections. No case of progressive multifocal leukoencephalopathy was observed. CONCLUSIONS: In our clinical experience outside the context of a clinical trial, natalizumab is largely reserved for CD patients with extensive ileocolonic disease who have failed conventional immunosuppressants and of at least 2 anti-tumor necrosis factor agents. This drug is, however, well tolerated and offers significant clinical improvement for more than a year in one-third of these difficult-to-treat CD patients.

Treatment for outpatients with comorbid schizophrenia and substance use disorders: a review

Aims: This review provides evidence of which interventions need to be part of effective outpatient integrated treatment for patients with comorbid schizophrenia and substance use disorders. Methods: A total of 14 randomized controlled trials were included. Effect sizes are provided to assess the magnitude of the treatments’ efficacy. Results: Despite the studies’ heterogeneity, we can conclude that certain programs (e.g., Behavioral Treatment for Substance Abuse in Schizophrenia) and specific interventions (e.g., motivational interviewing, family interventions) seem to be effective. Moreover, programs integrating multiple interventions are more likely to be positively related to better outcomes than single interventions. Finally, the lack of difference between effect sizes of assertive community treatment compared to case management suggests that a lower caseload is not necessary for positive treatment outcomes. Conclusion: Integrated treatment seems advantageous, although effect sizes are mostly modest. More homogeneous and qualitative sound studies are needed.
