Cervical interspinous bursitis in active polymyalgia rheumatica.

OBJECTIVE: To evaluate the inflammatory involvement of cervical interspinous bursae in patients with polymyalgia rheumatica (PMR) using MRI. METHODS: In all, 12 consecutive, untreated new patients with PMR were investigated. Five patients with fibromyalgia, two patients with cervical osteoarthritis and six patients with spondyloarthritis with neck pain served as controls. MRI of the cervical spine was performed in all 12 PMR case patients and in 13 control patients. Two of the four patients with PMR with pelvic girdle pain also had MRI of the lumbar spine. RESULTS: MRI evidence of interspinous cervical bursitis was found in all patients with PMR, and in three patients with fibromyalgia, in two with psoriatic spondylitis and one with cervical osteoarthritis. A moderate to marked (grade >or=2 on a semiquantitative 0-3 scale) cervical bursitis occurred significantly more frequently in patients with PMR than in control patients (83.3% compared with 30.7%, p = 0.015). In all patients and controls with cervical bursitis the involvement was found at the C5-C7 cervical interspaces. MRI of the lumbar spine showed lumbar interspinous bursitis at the L3-L5 lumbar interspaces in the two patients with PMR and pelvic girdle pain examined. CONCLUSIONS: Cervical interspinous bursitis is a likely basis for discomfort in the neck of patients with PMR. The prominent inflammatory involvement of cervical bursae supports the hypothesis that PMR is a disorder of prominent involvement of extra-articular synovial structures.

Frequency and duration of clinical remission in patients with peripheral psoriatic arthritis requiring second-line drugs.

OBJECTIVE: To evaluate the frequency and duration of clinical remission in patients with PsA. METHODS: All consecutive new outpatients with peripheral PsA requiring second-line drugs and RA observed between January 2000 and December 2005 were included in a prospective, case-control study. Primary end point was to assess the frequency of remission in peripheral PsA compared with RA. Secondary end points were to compare the duration of clinical remission during treatment and after therapy interruption, ACR 20, 50, 70 response rates and to detect any remission predictor at diagnosis. Treatment regimen was standardized in both groups. From January 2003 to December 2005, therapy was suspended in PsA patients and controls if achieving remission. RESULTS: One or more episodes of remission occurred in 57/236 (24.1%) PsA patients and in 20/268 (7.5%) controls (P < 0.001). The mean duration of remission was of 13 +/- 9.4 months in PsA patients and 4 +/- 3.7 in controls (P > 0.001). Remission episodes were more frequent in PsA patients treated with anti-TNF compared with those receiving traditional DMARDs (P > 0.001), with no differences regarding the duration. After therapy interruption, the remission duration was 12 +/- 2.4 months in PsA and 3 +/- 1.5 in RA (P < 0.001). No remission predictor at diagnosis resulted by multivariate analysis. CONCLUSION: Remission is possible in up to 24% of patients with peripheral PsA. It is significantly more frequent, but not longer, in patients receiving anti-TNF drugs compared with those treated with traditional DMARDs. Patients remain in remission for a long period after therapy interruption, thus suggesting an intermittent therapeutic strategy.

Stent implantation versus balloon angioplasty in chronic coronary occlusions: results from the GISSOC trial. Gruppo Italiano di Studio sullo Stent nelle Occlusioni Coronariche.

OBJECTIVES: In this multicenter, randomized trial we evaluated whether stent implantation after successful recanalization of a chronic coronary occlusion reduced the incidence of restenosis. BACKGROUND: Percutaneous transluminal coronary angioplasty (PTCA) in chronic total occlusions is associated with a higher rate of angiographic restenosis and reocclusion than PTCA in subtotal stenoses. Preliminary reports have suggested a decreased restenosis rate after stent implantation in coronary total occlusions. METHODS: We randomly assigned 110 patients with recanalized total occlusion to Palmaz-Schatz stent implantation, followed by 1 month of anticoagulant therapy versus no other treatment. The primary end point was the minimal lumen diameter (MLD) of the treated segment at follow-up, as determined by quantitative angiography at a core laboratory. RESULTS: Repeat coronary angiography was performed 9 months after the procedure in 88% of patients. The MLD (mean +/- SD) at follow-up was 1.74 +/- 0.88 mm in patients assigned to stent implantation and 0.85 +/- .75 mm in patients assigned to PTCA (p < 0.001). Stent implantation was associated with a lower incidence of restenosis (defined as diameter stenosis > or =50% at follow-up) (32% vs. 68%, p < 0.001) and reocclusion (8% vs. 34%, p = 0.003) than balloon PTCA. Likewise, stent-treated patients had less recurrent ischemia (14% vs. 46%, p = 0.002) and target lesion revascularization (5.3% vs. 22%, p = 0.038), but experienced a longer hospital stay. CONCLUSIONS: Palmaz-Schatz stent implantation after successful balloon PTCA of chronic total occlusions improves the midterm angiographic and clinical outcome and could be the preferred treatment option in selected patients with occluded vessels.

Inflammatory changes of hip synovial structures in polymyalgia rheumatica.

OBJECTIVE: To investigate the hip inflammatory lesions and to evaluate the accuracy of clinical examination compared to magnetic resonance imaging (MRI) in patients with polymyalgia rheumatica (PMR) with pelvic girdle symptoms. Secondary end-point was to evaluate the sensitivity and specificity of ultrasonography (US) compared to MRI in the assessment of hip lesions. METHODS: Case-control study of 20 consecutive PMR patients and 40 controls with different rheumatic conditions. Both groups were clinically assessed for the presence of hip synovitis, trochanteric, iliopsoas and ischiogluteal bursitis. Hip MRI was performed in all case-patients and in 10 controls. Both groups were examined by US. An additional group of 10 healthy controls was examined by hip US. RESULTS: Both MRI and US detected trochanteric bursitis in 100% of PMR patients, bilateral in 18/20 (90%), and in 12/40 (30%) controls (p < 0.001). Hip synovitis was detected in 17/20 (85%) by MRI and in 9/20 (45%) by US (p < 0.02) in case-patients and in 18/40 (45%) controls. In PMR, MRI and US showed iliopsoas bursitis in 10/20 (50%) and 6/20 (30%) and ischiogluteal bursitis in 5/20 (25%) and 4/20 (20%) with no differences compared to controls. Clinical examination showed a good accuracy for hip synovitis, trochanteric and ischiogluteal bursitis, while it overestimated the presence of iliopsoas bursitis. US was less sensitive than MRI for the detection of hip synovitis and iliopsoas bursitis (53% and 60%). CONCLUSION: Trochanteric bursitis represents the most frequent hip lesion in PMR. A careful physical examination allows to detect all inflammatory lesions excluding iliopsoas bursitis. US is less sensitive than MRI in the assessment of hip synovitis and iliopsoas bursitis.

Pulmonary hypertension in primary Sjögren's syndrome: report of a case and review of the literature.

A 61-year-old female with a history of vaginal dryness, Raynaud's phenomenon, xerostomia and xerophthalmia presented with exertional dyspnoea and weakness. Laboratory and instrumental examinations enabled us to make the diagnosis of primary Sjögren's syndrome, while cardiologic and imaging investigations evidenced isolated pulmonary hypertension and ruled out pulmonary fibrosis. Oral anticoagulant and furosemide therapy induced a partial improvement of exertional dyspnoea and weakness.

Technetium-99m-sestamibi SPECT to detect restenosis after successful percutaneous coronary angioplasty.

UNLABELLED: This study evaluated the accuracy of 99mTc SPECT in predicting restenosis after primary successful PTCA. METHODS: Thirty-seven patients with equivocal symptom-limited exercise stress testing were evaluated. All patients underwent separate day exercise-rest 99mTc-sestamibi SPECT. The perfusion studies were evaluated using three different methods of analysis: visual inspection, semiquantitative and quantitative polar map analysis. The perfusion studies were interpreted in absence of a pre-PTCA scan. All patients underwent a control coronary angiography within 1 mo. RESULTS: Sensitivity and specificity of 99mTc-sestamibi SPECT in predicting restenosis were 87.5-78%, 50-65% and 75-74% for visual inspection, semiquantitative and quantitative polar map analysis, respectively. Sensitivity and specificity related to the vascular territories were: LAD territory 93-73% (qualitative analysis), 53-60% (semiquantitative analysis), 80-67% (quantitative analysis); LCX territory 83-100% (qualitative analysis); and 33-100% (semiquantitative analysis), 67-100% (quantitative analysis); and RCA territory 67-80% (qualitative analysis), 67-60% (semiquantitative analysis), 67-80% (quantitative analysis). CONCLUSION: These data suggest that 99mTc-sestamibi SPECT is a useful noninvasive tool in the follow-up evaluation of patients who have undergone angiographically successful coronary angioplasty even in the absence of a pre-PTCA perfusion study.

Absence of correlation between coronary thrombosis and postatherectomy restenosis.

This study endeavored to assess whether thrombus in directional coronary atherectomy was correlated with later subsequent restenosis. We concluded that the presence of thrombus in native plaque is not correlated with the occurrence of postatherectomy restenosis.

Comparison of coronary lesions obtained by directional coronary atherectomy in unstable angina, stable angina, and restenosis after either atherectomy or angioplasty.

The present study investigated the incidence of the histopathologic lesions and of growth factor expression in a consecutive series of directional coronary atherectomy (DCA) samples from 40 unstable angina pectoris patients without prior acute myocardial infarction and compared the findings with those obtained in DCA samples from 18 patients with stable angina without previous infarction and 18 patients with restenosis. We investigated coronary thrombosis, neointimal hyperplasia, and inflammation. For unstable angina, we correlated the angiographic Ambrose plaque subtypes with the histopathologic findings. The immunophenotype of plaque cells and the growth factor expression were assessed with specific antibodies for cell characterization and for the expression of basic fibroblast and platelet-derived AA and AB growth factors and receptors. The incidence of coronary thrombosis was 35% in patients with unstable angina, 17% in those with stable angina, and 11% in patients with restenosis. Neointimal hyperplasia was found in 38% of unstable angina cases, in 17% of stable angina cases, and in 83% of restenosis cases. Inflammation without thrombus or accelerated progression occurred in 20% of unstable angina and 6% of stable angina samples. In 52% of unstable angina cases, inflammation coexisted with thrombosis and/or neointimal hyperplasia. In the unstable angina group, 71% of the plaques with thrombus had a corresponding angiographic pattern of complicated lesions. The growth factor expression, reported as percentage of cells immunostaining with different growth factor antibodies, was highest in restenosis, followed by unstable angina and stable angina lesions.(ABSTRACT TRUNCATED AT 250 WORDS)

Therapy with cyclosporine in psoriatic arthritis.

OBJECTIVE: To evaluate the efficacy and toxicity of cyclosporin A (CsA) in the treatment of patients with psoriatic arthritis (PsA). METHODS: We reviewed the literature dealing with CsA treatment of PsA. RESULTS: In the 1980s, some studies evaluating CsA in severe cases of psoriasis documented an improvement in the associated arthritis. Subsequently, open prospective studies included patients with active peripheral arthritis. Using initial CsA dose of 3 to 6 mg/kg/day, improvement in the clinical parameters was noted. A controlled trial showed that CsA and methotrexate (MTX) are equally effective treatment for PsA. CsA and MTX combination was effective in PsA patients resistant to previous second-line therapy. No studies have evaluated the efficacy of CsA on axial disease and on the progression of radiological damage. The most important side effect was nephrotoxicity. However, of 170 CsA-treated patients in 16 studies, only 10 (6%) discontinued the drug because of renal side effects. CONCLUSIONS: CsA seems to be an effective and safe therapy for PsA. However, controlled studies on large number of patients are necessary.

Erythrocyte sedimentation rate and C-reactive protein in the evaluation of disease activity and severity in polymyalgia rheumatica: a prospective follow-up study.

OBJECTIVE: To determine the frequency and clinical features of patients with polymyalgia rheumatica (PMR) and normal erythrocyte sedimentation rate (ESR) at diagnosis or during relapse/recurrence. To evaluate the usefulness of C-reactive protein (CRP) and ESR in the assessment of PMR activity. METHODS: A prospective follow-up study on 177 consecutive patients meeting the criteria for PMR diagnosed over a 5-year period was conducted in two Italian secondary referral centers of rheumatology. At diagnosis and during follow-up, ESR (Westergren method) and CRP (nephelometry) were measured in all patients. Phenotypic analysis of lymphocyte subpopulations was performed on 78 PMR patients at diagnosis. A two-color technique using the association of specific monoclonal antibodies was applied. A control group consisting of 18 healthy adults older than 60 years was matched for age and sex with the PMR patients. RESULTS: Ten of 177 (6%) patients had normal ESR values at diagnosis (< or = 30 mm/h). Patients with normal ESR were predominantly men and had lower CRP levels; systemic signs and symptoms were more frequent in patients with higher ESR. The percentages of circulating CD8+ cells were similar in the two groups. CRP values at diagnosis were normal in only 2 of 177 (1%) patients. CRP values were elevated in 9 of 10 patients with normal ESR at diagnosis. Twenty-five episodes of relapse/recurrence with normal ESR occurred in 17 patients. CRP was high in 62% of these episodes. Results of univariate analysis indicated that the 10th percentile for ESR (40 mm/h) and the 70th percentile for CRP (7.8 mg/dL) values at diagnosis were the best cutoff points that discriminate between patients with and without relapse/recurrence. Cox proportional hazards modeling showed that ESR greater than 40 mm/h and CRP greater than 7.8 mg/dL at diagnosis were the two variables that independently increased the risk of relapse/recurrence. However, the relative risk related to ESR was twice than that related to CRP (4.9 vs 2.1). CONCLUSION: PMR with a normal ESR at diagnosis was infrequent in our study compared with previous studies. ESR was a superior predictor of relapse than CRP. However, CRP was a more sensitive indicator of current disease activity.

Factors affecting the therapeutic choice in patients with multivessel coronary artery disease. The Studio Lombardo Angiografia Multivasali (SLAM) Study Group.

OBJECTIVE: To assess how clinical and angiographic findings are related to the decision to carry out coronary angioplasty (PTCA) or coronary bypass grafting in patients with multivessel coronary artery disease. DESIGN: Prospective survey carried out in 14 centres in the Lombardia region of Italy. PATIENTS: 1468 consecutive patients under going coronary arteriography for known or suspected ischaemic heart disease between May and October 1994, who were found to have multivessel coronary artery disease. MAIN OUTCOME MEASURES: Multivariate analysis was undertaken using stepwise logistic regression to identify the clinical and angiographic variables correlated with revascularisation (v medical treatment) in all of patients, and with surgery (v angioplasty) in the subset of revascularised patients. RESULTS: In all patients the clinical decision after coronary arteriography was made by physicians of each participating centre on the basis of their experience and clinical judgment: 53% of patients had bypass surgery, 28% had PTCA, and 19% continued medical treatment. The choice of a revascularisation procedure was directly related to a clinical diagnosis of unstable angina (P < < 0.001), the presence of left anterior descending artery disease (P < < 0.001), and to an ejection fraction > or = 40% (P < < 0.001), and inversely related to history of previous coronary bypass surgery (P < < 0.001). In revascularised patients, bypass surgery was the preferred treatment in patients with left anterior descending artery disease (P < < 0.001), three-vessel disease (P < < 0.001), and in those with at least one occluded vessel (P = 0.008). The choice of PTCA was significantly related to history of previous PTCA (P < < 0.001) or coronary bypass surgery (P < < 0.001), to a clinical diagnosis of non-Q wave myocardial infarction (P = 0.002), and to the possibility of implanting an intracoronary stent (P = 0.01). CONCLUSIONS: Bypass surgery is still the most widely used treatment for patients with multivessel coronary artery disease. This analysis provides a basis for comparison with future developments in the treatment of such patients. Further advancements in PTCA technology are needed to tilt the balance in favour of this less invasive procedure.

Renal tolerability of three commonly employed non-steroidal anti-inflammatory drugs in elderly patients with osteoarthritis.

OBJECTIVE: The primary endpoint of this study was to compare the renal tolerability of amtolmetin guacyl (AMG), diclofenac and rofecoxib in elderly patients with symptomatic osteoarthritis (OA). The assessment of efficacy was the secondary endpoint. METHODS: 90 patients who satisfied the American College of Rheumatology classification criteria for hand, hip or knee OA were randomly assigned to 3 treatment groups receiving either: AMG 1,200 mg over thefirst 3 days and and 600 mg/day thereafter; diclofenac 150 mg/day; or rofecoxib 25 mg/day for 2 weeks. At baseline and after therapy patients were clinically assessed by the same examiner who was unaware of the treatment arm assignement. Serum and urinary parameters of renal function and the outcome measures of efficacy were evaluated before (t(0)) and after therapy (t(1)). RESULTS: Diclofenac produced a significant reduction in creatinine clearance (t(0) = 88.93 +/- 11.59; t(1) = 75.90 +/- 16.32; p: < 0.001) and in the daily urine volume (t(0) = 1,337.93 +/- 202.07; t(1) = 1,027.59 +/- 249.14; p: < 0.001). In the same treatment group a significant increase in serum creatinine, blood urea nitrogen, uric acid and potassium were observed. Rofecoxib treated patients showed a significant increase in body weight (t(0) = 75.31 +/- 4.26; t(1) = 76.54 +/- 4.84; p: < 0.001), systolic blood pressure (t(0) = 144 +/- 10.86; t(1) = 154 +/- 11.8; p < 0.001), diastolic blood pressure (t(0) = 80 +/- 6.05; t(1) = 89 +/- 7.66; p < 0.001) and serum sodium (t(0) = 138.73 +/- 1.28; t(1) = 140.12 +/- 1.80; p < 0.005) associated with a significant decrease in the daily urine volume (t(0) = 1294.64 +/- 205.21; t, = 1,115.48 +/- 238.47; p < 0.001) and creatinine clearance (t(0)= 86.73 +/- 8.14; t(1) = 83.15 +/- 7.96; p < 0.01). No significant changes in the clinical and humoral parameters were recorded in AMG treated patients. Diclofenac was more efficacious than the other 2 drugs (p < 0.001). No differences were observed between AMG and rofecoxib. Side effects related to altered kidney function were significantly higher in the rofecoxib group (p < 0.005). CONCLUSION: Diclofenac mainly impaired blood renal flow and the glomerularfiltration rate, while rofecoxib negatively influenced the renal sodium-water exchange. AMG demonstrated a renal sparing effect, although the eract mechanism is unclear

Tuberculous spondylitis as a cause of inflammatory spinal pain: a report of 4 cases.

Patients are said to have inflammatory spinal pain if they fulfill at presentation 4 of the following 5 criteria: duration of spinal discomfort for at least 3 months, spinal morning stiffness, age less than 40, insidious onset of symptoms, and no relief from pain with rest, but improvement with exercise. Inflammatory spinal pain is typical of the spondylarthropathies. Only in a minority of the cases it is found in other rheumatic disorders such as rheumatoid arthritis, fibromyalgia or infectious spondyilitis. Tuberculous spondylitis is rarely mentioned as a possible cause of inflammatory spinal pain. We describe 4 patients with tuberculous spondylitis seen over a 3-year period who met the clinical criteria for inflammatory spinal pain at presentation. We conclude that inflammatory spinal pain may be a presenting feature, albeit rare, of tuberculous spondylitis. Awareness of this finding should help facilitate the proper diagnosis and the institution of appropriate therapy.

Distal extremity swelling with pitting edema in psoriatic arthritis: a case-control study.

OBJECTIVE: To evaluate the frequency and the clinical characteristics of distal extremity swelling with pitting edema in patients with psoriatic arthritis (PsA). METHODS: This was a case-control study of consecutive outpatients with PsA (old and new diagnosis) observed over a 3-month period in three secondary referral centers in Italy. As controls we used the two consecutive rheumatic outpatients, excluding those with spondylarthropathies, observed after a PsA patient. The demographic and clinical features were assessed by clinical examination and review of the medical records. RESULTS: A total of 183 patients with PsA and 366 controls were evaluated. Distal extremity swelling with pitting edema was recorded in 39/183 (21%) PsA patients and in 18/366 (4.9%) controls (p < 0.0001). In 8/39 (20%) patients this feature presented as a first, isolated manifestation of PsA, and in 8 others it was associated with other features of PsA at diagnosis. The upper and lower extremities were affected, predominantly asymmetrically, in 40% and 60% of the cases respectively. In patients with pitting edema compared to those without this feature, the frequency of Achilles enthesitis and plantar fasciitis, calculated together, was higher (p < 0.05) and the duration of arthritis was significantly lower (p = 0.02). In 7 patients the clinical evidence of a predominant involvement of tenosynovial structures was confirmed by MRI. CONCLUSION: Upper or lower distal extremity swelling with pitting edema due to tenosynovitis, usually unilateral, is a common feature in PsA patients and may represent the first, isolated manifestation of the disease.

Myocardial metabolism during intracoronary thrombolysis. Two illustrative cases.

Arterial and coronary sinus difference for potassium, lactate, glucose, free fatty acids and creatine kinase was measured every 5 minutes in two patients undergoing successful intracoronary thrombolysis of left anterior descending occlusion. In the first patient, reperfusion, 160 minutes after the onset of pain, was followed by a transient and limited release of creatine kinase in the coronary sinus, improvement in the electrocardiogram and restitution of left ventricular contraction. In the second patient, reperfusion 365 minutes after the onset of pain, was also accompanied by a limited release of creatine kinase. Reocclusion of the left anterior descending coronary artery, however, necessitated further thrombolysis which led to a massive release of creatine kinase and permanent loss of wall-motion. It is suggested that, in this case, reperfusion damage had occurred. The arteriovenous differences showed a wash-out of potassium and lactate during reperfusion in each case. The interpretation of the entire sequence of arteriovenous changes, however, could be shown to depend critically on the state of regional perfusion.

Effects of short-term, high dose, heparin therapy on biochemical markers of bone metabolism.

To evaluate the effects of the short-term, high-dose sodium heparin therapy on biochemical markers of bone metabolism, we studied 20 patients (11 males and 9 females) with pulmonary embolism, treated with sodium heparin (daily dose range: 40,000-45,000 I.U. by continuous i.v. infusion). Heparin therapy lasted 5-7 days, after which patients received warfarin over 12 months. Eleven patients (6 males and 5 females) with ischaemic stroke, treated with i.v. glycerol and pentoxifilline, were used as controls. Before and after therapy serum and urinary markers of bone metabolism were evaluated; in 12 heparin-treated pts., the parameters were also evaluated 4 months after discontinuation of warfarin therapy. After heparin therapy a significant reduction vs. basal value was observed in levels of serum osteocalcin (ng/ml;mean + SEM): 3.32 & 0.19 vs. 2.05 + 0.21; p < 0.001. In the 12 patients evaluated 4 months after discontinuation of warfarin therapy, serum osteocalcin levels returned to basal value: 3.41 + 0.12 ng/ml (p:n.s.). No significant changes of the examined parameters were observed in controls. In conclusion, our data seem to indicate an effect of i.v. short-term heparin therapy on bone metabolism. This effect seems to be characterized by an inhibition of osteoblast function as suggested by the reduction of serum osteocalcin levels.

Coexisting Behçet's syndrome and spondyloarthritis.

A patient suffering from Behçet's syndrome and undifferentiated spondyloarthritis developed dactylitis and psoriasis over the next three years.

Invasive and echocardiographic evaluation of non-Q myocardial infarction with isolated stenosis of descending anterior coronary artery.

Prognostic and clinical characteristics of acute myocardial infarction (AMI) can usually justify surgical and/or angioplastic approach if the residual ventricular function is still good. Multivessel disease frequently complicates results interpretation. We studied with 2D echocardiography and coronary angiography two groups of patients with one vessel stenosis located on anterior descending (AD) and previous AMI (means 19 days): 23 patients with spontaneous non-Q infarction (group 1), and 23 patients with Q infarction. Left ventricular function was better in group 1. Percent occlusion of AD was lower in group 1 and angiographic AD caliber was significantly higher. Differences between groups were much more evident in subgroups with proximal stenosis of AD: patients of non-Q subgroups had very good left ventricular function but frequently had post-AMI instable angina (88%). Our results underline the usefulness of aggressive diagnostic and therapeutic approach in non-Q AMI, because of higher amount of myocardium at risk.

[Fluoxetin combined with cyclobenzaprine in the treatment of fibromyalgia]. / Fluoxetina associata a ciclobenzaprina nel trattamento della fibromialgia.

The aim of this study is to evaluate the effectiveness of fluoxetin associated with cyclobenzaprine vs cyclobenzaprine in the treatment of fibromyalgia. Twenty-one females with fibromyalgia were randomly assigned to 2 groups: group A (11 patients) was treated over 12 weeks with fluoxetin (20 mg/die) and cyclobenzaprine (10 mg/die), group B with cyclobenzaprine (10 mg/die). Basally and after 12 weeks patient self-assessment of pain, number of painful tender points, tender points index and morning stiffness were evaluated. The study has shown a significant improvement of the examined parameters in both treatment groups; however the comparison between the two groups showed a greater effectiveness, statistically significant, of the treatment with Fluoxetin associated with cyclobenzaprine.
