Background: Throwing injuries of the shoulder and elbow are common among youth baseball players. Hypothesis: A prevention program will reduce the incidence of throwing injuries of the shoulder and elbow by 50% among youth baseball players. Study Design: Randomized controlled trial; Level of evidence, 1. Methods: The authors block randomized 16 youth baseball teams consisting of 237 players aged 9 to 11 years into an intervention group (8 teams, 117 players) and a control group (8 teams, 120 players). The intervention program consisted of 5 stretching, 2 dynamic mobility, and 2 balance training exercises performed during warm-up. Both groups were followed up for 12 months, during which the incidence of shoulder and elbow injuries was recorded. In addition, ball speed during pitching as a performance-related factor and variables of physical function (passive range of motion of the elbow, shoulder and hip, dynamic balance, and thoracic kyphosis angle) were assessed during the pre- and postintervention periods. Results: The incidence of shoulder and elbow injuries in the intervention group (1.7 per 1000 athlete-exposures) was significantly lower than that in the control group (3.1 per 1000 athlete-exposures) (hazard ratio, 1.940; 95% CI, 1.175-3.205; P =.010). The factors related to pitching performance, as assessed by ball speed, tended to increase in the intervention group as compared with the control group (P =.010). The program also improved shoulder horizontal adduction deficits on the dominant side, hip internal rotation on the nondominant side, and the thoracic kyphosis angle. Conclusion: A prevention program decreases throwing injuries of the shoulder and elbow and enhances the parameter of pitching performance in youth baseball players. [ABSTRACT FROM AUTHOR]

The Unified Protocol for Transdiagnostic Treatment of Emotional Disorders in Children (UP-C) is an intervention for children aged 7 to 13 targeting high negative emotion, emotional reactivity, and emotion regulation deficits common across emotional disorders. Our objective was to collect pilot randomized controlled trial (RCT) data on the efficacy of the UP-C, comparing UP-C with an active, anxiety-focused intervention. Participants were 47 children with at least one primary anxiety disorder; approximately one half had elevated depression symptoms. Participants received either UP-C or the anxiety-focused control treatment. No condition-related differences were found with respect to diagnostic remission and anxiety symptoms. However, differences in favor of UP-C were observed with respect to treatment response at follow-up, depression symptoms, sadness dysregulation, and cognitive reappraisal. Results provide preliminary evidence that the UP-C may be at least as efficacious in treating anxiety as well-supported anxiety-specific treatment protocols and may produce greater gains in certain emotion reactivity and regulation variables.

Objective: To evaluate the effectiveness of acupuncture in patients with vascular cognitive impairment no dementia (VCIND) in comparison with citicoline, an agent for cognitive disturbances associated with chronic cerebral disorders. Design: A randomized controlled multicenter trial. Setting: In three hospitals in Beijing, China. Subjects: A total of 216 patients with VCIND were recruited. Interventions: Patients with VCIND (mean age of 65.4 years) were randomized to receive acupuncture (two sessions per week) or oral citicoline (100 mg three times daily) over three months. Main measures: The primary outcome was the change from baseline to three months in cognitive symptom, measured by Alzheimer's disease Assessment Scale, cognitive subscale (ADAS-cog). Secondary outcomes included changes from baseline to six months in ADAS-cog, executive function measured by the Clock Drawing Test (CDT), and functional disability measured by the Ability of Daily Living (ADL) scale at three and six months. Results: At three months, the acupuncture group had a greater decrease in mean ADAS-cog score (−2.33 ± 0.31) than the citicoline group (−1.38 ± 0.34) with a mean difference of −0.95 (95% CI, −1.84 to −0.07, P = 0.035). The mean change from baseline to six months in ADAS-cog also significantly favored acupuncture treatments (acupuncture change −2.61 vs citicoline −1.25, difference: −1.36 points; 95% CI, −2.20 to −0.51; P = 0.002). There was no difference between the two groups on CDT and ADL scores at either time point. Conclusion: Compared with citicoline, acupuncture has comparable and even superior efficacy with improved cognitive and daily living performance as a complementary and alternative medicine treatment for VCIND.

Objective: This study aimed to assess if external focus instructions result in greater improvements in motor skill and automaticity compared to internal focus instructions in stroke patients. Design: Double-blind randomized controlled trial. Setting: Inpatient stroke rehabilitation unit. Subjects: A total of 63 stroke patients (Meanage = 59.6 ± 10.7 years; Meandays since stroke = 28.5 ± 16.6; MedianFunctional Ambulation Categories = 4). Interventions: Patients were randomly assigned to an internal (N = 31) or external (N = 32) focus instruction group. Both groups practiced a balance board stabilization task, three times per week, for three weeks. Balance performance was assessed at baseline, and after one and three weeks of practice. Main measures: Primary outcome was the threshold stiffness (Nm/rad) at which patients could stay balanced. Secondary outcomes were patients' sway (root-mean-square error in degrees) at the baseline threshold stiffness under single- and dual-task conditions, and their performance on the Timed Up and Go Test and Utrecht Scale for Evaluation of Rehabilitation. Results: Both groups achieved similar improvements in threshold stiffness (∆= 27.1 ± 21.1 Nm/rad), and single- (∆= 1.8 ± 2.3° root-mean-square error) and dual-task sway (∆= 1.7 ± 2.1° root-mean-square error) after three weeks of practice. No differences were found in improvements in clinical tests of balance and mobility. Patients with comparatively good balance and sensory function, and low attention capacity showed greatest improvements with external focus instructions. Conclusion: External focus instructions did not result in greater improvement in balance skill in stroke patients compared to internal focus instructions. Results suggest that tailoring instructions to the individual stroke patient may result in optimal improvements in motor skill. [ABSTRACT FROM AUTHOR]

Objective: To evaluate the effectiveness of acupuncture for pain relief and function improvement in patients with knee osteoarthritis and to determine the feasibility of an eight-week acupuncture intervention. Design: Pilot randomized controlled trial. Setting: Three teaching hospitals in China. Subjects: Patients with knee osteoarthritis (Kellgren grade II or III). Interventions: Patients were randomly assigned to an eight-week (three sessions per week) intervention of either traditional Chinese acupuncture or sham acupuncture. Main measures: The primary outcome was response rate—the proportion of patients achieving score ⩾36% decrease in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain and function at week 8 compared with baseline. Secondary outcomes included pain, function and quality of life. Results: Of 42 patients randomized, 36 (85.7%) completed the study. There was no significant difference in response rate between the traditional Chinese acupuncture and control groups: 61.9% (13 of 21) versus 42.9% (9 of 21) achieved score ⩾36% decrease in WOMAC pain and function at week 8 (P = 0.217). The sum of WOMAC pain and function scores at week 8 was 11.6 (9.1) in the traditional Chinese acupuncture group compared with 16.3 (10.9) in the control group (P = 0.183). There was no significant difference between groups. Three adverse events were recorded and were classified as mild. Conclusion: It showed that three sessions per week acupuncture intervention of knee osteoarthritis was feasible and safe. No difference was observed between groups due to small sample size. Larger (sample size ⩾ 296) randomized controlled trials of this intervention appear justified. [ABSTRACT FROM AUTHOR]

Little is known about the effects of distraction techniques when undertaking medical procedures with hospitalized pediatric patients in Asian countries. This study examined the effects of distraction interventions on behavioral distress related to venipuncture procedures in Taiwanese children aged 3 to 7 years. Using concealed randomization, eligible children were allocated to receive a picture book (n = 92), or animated cartoon (n = 92) compared with routine oral instructions (n = 92), when being injected with an intravenous cannula. Two trained observers independently scored the responses of each child using the Observational Scale of Behavioral Distress–Revised before, during, and after the procedure. All children experienced distress during needle insertion, but distress was less in the distraction-based intervention groups. Moreover, distraction interventions were more effective for children aged 4 to 5 years. Our culturally tailored intervention engaged child participants, was age-appropriate, and could be adapted for use in other Chinese cultures. [ABSTRACT FROM AUTHOR]

Objective: Aim of this trial was to compare efficacy of activated platelet-rich plasma against hyaluronic acid as intra-articular injections to people with osteoarthritis of the knee. Design: Phase-2 randomized controlled trial, with blind patients and outcome assessors. Setting: Outpatient rehabilitation service; years 2011-2013. Subjects: Patients with knee osteoarthritis grades 2-3 at magnetic resonance imaging (MRI) were included after consent and randomized. Target sample size was 25 patients per group. Interventions: Patients received three activated platelet-rich plasma (intervention group) or hyaluronic acid (controls) intra-articular injections at 4-week intervals. Main measures: Main outcome measure was proportion of patients with >1 grade improvement at six months from last injection, as assessed by a radiologist blind to study group. Patients were evaluated over time clinically and with functional scales (Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Lysholm, Tegner, American Knee Society Score (AKSS), Lequesne, visual analogue scale (VAS) for pain). Results: Overall, 30 patients were randomized to intervention and 28 to control group. For primary outcome, 28 patients (29 knees) in the intervention and 22 (25 knees) in the control group were available. Patients with at least 1 grade improvement at repeat MRI were 14 (48.3%) in the intervention and 2 (8%) in the control group (P < 0.003). Improvement in symptoms and functional scales was consistently higher in the intervention group. No side-effects were observed in either group. Conclusion: Activated platelet-rich plasma reduces articular damage as evident at MRI, as soon as six months after treatment; it reduces pain and improves patient's function and overall quality of life.

Background: Barbotage (needling and lavage) is often applied in the treatment of calcific tendinitis of the rotator cuff (RCCT). In a previously published randomized controlled trial, we reported superior clinical and radiological 1-year outcomes for barbotage combined with a corticosteroid injection in the subacromial bursa (SAIC) compared with an isolated SAIC. There are no trials with a midterm or long-term follow-up of barbotage available. Purpose: To compare the 5-year results of 2 regularly applied treatments of RCCT: ultrasound (US)–guided barbotage combined with a SAIC (group 1) versus an isolated US-guided SAIC (group 2). Study Design: Randomized controlled trial; Level of evidence, 1. Methods: Patients were randomly assigned to group 1 or 2 and evaluated before and after treatment at regular time points until 12 months and also at 5 years using the Constant score (CS), the Western Ontario Rotator Cuff Index (WORC), and the Disabilities of the Arm, Shoulder and Hand (DASH). The calcification location and size and Gärtner classification were assessed on radiographs. The rotator cuff condition was evaluated with US. Results were analyzed using t tests, linear regression, and a mixed model for repeated measures. Results: Forty-eight patients were included (mean age, 52.0 ± 7.3 years; 25 [52%] female) with a mean baseline CS of 68.7 ± 11.9. After a mean follow-up of 5.1 ± 0.5 years, the mean CS was 90 (95% CI, 83.0-95.9) in group 1 versus 87 (95% CI, 80.5-93.5) in group 2 (P = .58). The mean improvement in the CS in group 1 was 18 (95% CI, 12.3-23.0) versus 21 (95% CI, 16.2-26.2) in group 2 (P = .32). There was total resorption in 62% of group 1 and 73% of group 2 (P = .45). The US evaluation of the rotator cuff condition showed no significant differences between the groups. With the mixed model for repeated measures, taking into account the baseline CS and Gärtner classification, the mean treatment effect for barbotage was 6 (95% CI, –8.9 to 21.5), but without statistical significance. Follow-up scores were significantly associated with baseline scores and the duration of follow-up. Results for the DASH and WORC were similar. There were no significant complications, but 4 patients in group 1 and 16 in group 2 underwent additional treatment during the follow-up period (P < .001). Conclusion: No more significant differences were found in the clinical and radiological outcomes between barbotage combined with a SAIC versus an isolated SAIC after 5 years of follow-up. Registration: NTR2282 (Dutch Trial Registry). [ABSTRACT FROM AUTHOR]

Two blinded single-dose studies randomized children 6 months to 11 years old with fever to receive ibuprofen (IBU) pediatric suspension 7.5 mg/kg or acetaminophen (APAP) suspension 10 to 15 mg/kg. The primary efficacy parameter was time-weighted sum of temperature differences (TWSTD) from baseline through 8 hours for each study. Secondary end points included TWSTD from baseline through 6 hours, time to onset and duration of temperature control, and proportion with temperature control. Studies were pooled for post hoc analyses of efficacy and adverse event end points. The primary efficacy parameter significantly favored IBU over APAP in study 1 and the pooled analysis (both P < .001), but was not significant in study 2. Onset of temperature control significantly favored IBU in study 2 (P = .007). Individual and pooled secondary efficacy outcomes supported significant advantages (P < .05) of IBU over APAP. IBU pediatric suspension provided greater temperature reduction versus acetaminophen in febrile children, with a comparable safety profile. [ABSTRACT FROM AUTHOR]

Objective: To compare efficacy of a web-based multimodal training programme, ‘Move it to improve it’ (MitiiTM), to usual care on gross motor capacity and performance for children with an acquired brain injury. Design: Randomized waitlist controlled trial. Setting: Home environment. Participants: A total of 60 independently ambulant children (30 in each group), minimum 12 months post-acquired brain injury were recruited and randomly allocated to receive either 20 weeks of MitiiTM training (30 minutes/day, six days/week, total 60 hours) immediately, or waitlisted (usual care control group) for 20 weeks. A total of 58 children completed baseline assessments (32 males; age 11 years 11 months ± 2 years 6 months; Gross Motor Function Classification System equivalent I = 29, II = 29). Intervention: The MitiiTM program comprised of gross motor, upper limb and visual perception/cognitive activities. Main measures: The primary outcome was 30-second, repetition maximum functional strength tests for the lower limb (sit-to-stand, step-ups, half-kneel to stand). Secondary outcomes were the 6-minute walk test, High-level Mobility Assessment Tool, Timed Up and Go Test and habitual physical activity as captured by four-day accelerometry. Results: Groups were equivalent at baseline on demographic and clinical measures. The MitiiTM group demonstrated significantly greater improvements on combined score of functional strength tests (mean difference 10.19 repetitions; 95% confidence interval, 3.26–17.11; p = 0.006) compared with the control group. There were no other between-group differences on secondary outcomes. Conclusion: Although the MitiiTM programme demonstrated statistically significant improvements in the functional strength tests of the lower limb, results did not exceed the minimum detectable change and cannot be considered clinically relevant for children with an acquired brain injury.

Background: Achilles tendinopathy (AT) is a common and difficult to treat musculoskeletal disorder. Purpose: To examine whether 1 injection of platelet-rich plasma (PRP) would improve outcomes more effectively than placebo (saline) after 3 months in patients with AT. Study Design: Randomized controlled trial; Level of evidence, 1. Methods: A total of 24 patients with chronic AT (median disease duration, 33 months) were randomized (1:1) to receive either a blinded injection of PRP (n = 12) or saline (n = 12). The primary endpoint was improvement in Victorian Institute of Sports Assessment–Achilles (VISA-A) score at 3 months. Secondary outcomes were pain at rest, pain while walking, pain when tendon was squeezed, ultrasonographic changes in tendon thickness, and color Doppler activity. Patients were informed that they could drop out after 3 months if they were dissatisfied with the treatment. Results: After 3 months, all 24 patients were reassessed (no dropouts). No difference between the PRP and the saline group could be observed with regard to the primary outcome (VISA-A score: mean difference [MD], –1.3; 95% CI, −17.8 to 15.2; P = .868). Secondary outcomes were pain at rest (MD, 1.6; 95% CI, −0.5 to 3.7; P = .137), pain while walking (MD, 0.8; 95% CI, −1.8 to 3.3; P = .544), pain when tendon was squeezed (MD, 0.3; 95% CI, −0.2 to 0.9; P = .208), color Doppler activity (MD, 0.3; 95% CI, −0.2 to 0.8; P = .260), and tendon thickness (MD, 0.8 mm; 95% CI, 0.1 to 1.6 mm; P = .030). After the 3-month follow-up, a large dropout was observed: 75% of patients in the PRP group and 33% in the saline group. Conclusion: PRP injection did not result in an improved VISA-A score over a 3-month period in patients with chronic AT compared with placebo. The only secondary outcome demonstrating a statistically significant difference between the groups was change in tendon thickness; this difference indicates that a PRP injection could increase tendon thickness compared with saline injection. The conclusions are limited to the 3 months after treatment owing to the large dropout rate. [ABSTRACT FROM AUTHOR]

Biological mediators have been used to enhance periodontal regeneration. The aim of this prospective randomized controlled study was to evaluate the safety and effectiveness of 3 doses of fibroblast growth factor 2 (FGF-2) when combined with a β-tricalcium phosphate (β-TCP) scaffold carrier placed in vertical infrabony periodontal defects in adult patients. In this double-blinded, dose-verification, externally monitored clinical study, 88 patients who required surgical intervention to treat a qualifying infrabony periodontal defect were randomized to 1 of 4 treatment groups-β-TCP alone (control) and 0.1% recombinant human FGF-2 (rh-FGF-2), 0.3% rh-FGF-2, and 0.4% rh-FGF-2 with β-TCP-following scaling and root planing of the tooth prior to a surgical appointment. Flap surgery was performed with EDTA conditioning of the root prior to device implantation. There were no statistically significant differences in patient demographics and baseline characteristics among the 4 treatment groups. When a composite outcome of gain in clinical attachment of 1.5 mm was used with a linear bone growth of 2.5 mm, a dose response pattern detected a plateau in the 0.3% and 0.4% rh-FGF-2/β-TCP groups with significant improvements over control and 0.1% rh-FGF-2/β-TCP groups. The success rate at 6 mo was 71% in the 2 higher-concentration groups, as compared with 45% in the control and lowest treatment groups. Percentage bone fill in the 2 higher-concentration groups was 75% and 71%, compared with 63% and 61% in the control and lowest treatment group. No increases in specific antibody to rh-FGF-2 were detected, and no serious adverse events related to the products were reported. The results from this multicenter trial demonstrated that the treatment of infrabony vertical periodontal defects can be enhanced with the addition of rh-FGF-2/β-TCP (ClinicalTrials.gov NCT01728844).

The role of cholinergic abnormalities in autism was recently evidenced and there is a growing interest in cholinergic modulation, emerging for targeting autistic symptoms. Galantamine is an acetylcholinesterase inhibitor and an allosteric potentiator of nicotinic receptors. This study aimed to evaluate the possible effects of galantamine as an augmentative therapy to risperidone, in autistic children. In this randomized, double-blind, placebo-controlled, parallel-group study, 40 outpatients aged 4–12 years whom had a diagnosis of autism (DSM IV-TR) and a score of 12 or higher on the Aberrant Behavior Checklist-Community (ABC-C) Irritability subscale were equally randomized to receive either galantamine (up to 24 mg/day) or placebo, in addition to risperidone (up to 2 mg/day), for 10 weeks. We rated participants by ABC-C and a side effects checklist, at baseline and at weeks 5 and 10. By the study endpoint, the galantamine-treated patients showed significantly greater improvement in the Irritability (P = 0.017) and Lethargy/Social Withdrawal (P = 0.005) subscales than the placebo group. The difference between the two groups in the frequency of side effects was not significant. In conclusion, galantamine augmentation was shown to be a relatively effective and safe augmentative strategy for alleviating some of the autism-related symptoms. [ABSTRACT FROM PUBLISHER]

The article presents the study which examined the effectiveness of platelet-rich plasma (PRP) as a treatment for patellar tendinopathy. Among the measures used in the study are the Victorian Institute of Sports Assessment (VISA) score for patellar tendinopathy, the visual analog scale (VAS) for pain, and the Tegner activity scale. Based on the results, the apparent benefits of PRP as treatment dissipate over time.

The article reports a study to evaluate whether a single injection of platelet-rich plasma (PRP) is more effective than placebo (saline) or glucocorticoid in reducing pain in adults with lateral epicondylitis (LE) after 3 months. The results proved that neither PRP nor glucocorticoid was superior to saline in pain reduction in LE at the primary end point at 3 months. However, injection of glucocorticoid had a short-term pain reducing effect at 1 month in contrast to the other therapies.

A randomized control trial is carried out where a tractio group recieved lumbar extension traction in addition to hot packs and interferential therepy had better effect than the control group.

The article discusses a study conducted to examine the safety and efficacy of onabotulinumtoxinA (Botox) for plantarflexor overactivity following stroke. It highlights that Botulinum toxin type A (BoNT-A) is treatment of choice to reduce the neurogenic component of focal hypertonia; and leads to muscle overactivity causing equinovarus ankle deformity after stroke. The result suggests that its injection for ankle flexor overactivity after stroke was safe but did not alter local spasticity.

Background: The authors developed a novel technique to improve tendon-bone healing by hybridizing calcium phosphate (CaP) with a tendon graft using an alternating soaking process. Hypothesis: Anterior cruciate ligament (ACL) reconstruction using the CaP-hybridized tendon graft would have a better clinical outcome and reduce the percentage of bone tunnel enlargement compared with a conventional method because of the enhanced anchoring between the tendon graft and the bone. Study Design: Randomized controlled trial; Level of evidence, 1. Methods: Patients (N = 64) with unilateral ACL rupture underwent arthroscopically assisted single-bundle ACL reconstruction using a 4-strand semitendinosus tendon or 4-strand semitendinosus and gracilis tendons with EndoButton femoral fixation and screw washer tibial fixation. These patients were equally randomized to undergo the CaP (n = 32) or conventional (n = 32) method using a transtibial tunnel approach according to the closed envelope method. In the CaP group, the tendon graft was hybridized with the CaP at both ends of the graft. One surgeon performed all reconstructions without knowing which graft was prepared. Patients’ backgrounds regarding age at surgery, gender, period before surgery, and associated meniscal injuries were similar in the 2 groups. All patients followed the same postoperative protocol. At 1 and 2 years after surgery, they were evaluated with the manual knee laxity test, KT-1000 arthrometry, International Knee Documentation Committee (IKDC) examination form, Tegner scale, and Lysholm scale. Also, 1 year postoperatively, bone tunnel enlargement was analyzed using computed tomography, intensity of the tendon graft by magnetic resonance imaging (MRI), and tendon graft appearance by arthroscopic examination. All the examinations were performed blindly. Results: All patients underwent a minimum 2-year follow-up. KT-1000 arthrometry data indicated statistically significant decreased average anterior tibial translation in the CaP group compared with the conventional method group: 1.0 6 2.0 mm versus 1.9 6 1.6 mm (P\.05), respectively, at 1 year; 1.6 6 2.1 mm versus 2.6 6 2.4 mm (P\.05), respectively, at 2 years. The Lysholm score was higher in the CaP group than in the conventional method group at 2 years (96.9 6 4.3 vs 91.7 6 13.3, P\.05). The CaP-hybridized tendon graft reduced the percentage of bone tunnel enlargement of the anteroposterior diameter at the main joint aperture site 1 year postoperatively (femoral side: 15.5% 6 13.4% vs 22.1% 6 16.4%, P\.05; tibial side: 19.3% 6 17.1% vs 26.1% 6 13.7%, P\.05). The results of the pivot-shift test, IKDC grade, and Tegner score; the intensity of the tendon graft (MRI); and arthroscopic appearance were not significantly different at both follow-up periods in the 2 groups. Conclusion: The CaP-hybridized tendon graft improved anterior knee stability and Lysholm scores at the 2-year follow-up and improved anterior knee stability and reduced the percentage of bone tunnel enlargement in both tunnels at the 1-year follow-up compared with the conventional method for single-bundle ACL reconstruction. However, longer follow-up is needed to investigate the appearance of any increased instability. [ABSTRACT FROM AUTHOR]

Objective: To examine the effects of foot orthosis intervention during a 60-minute running test in pronated-foot runners with overuse knee or foot pain during running.Design: A randomized, controlled design.Setting: Sports gym.Participants: Twenty-four runners with pronated foot who experienced pain over anterior knee or foot region during running were recruited and randomized into the treatment, or the control, group.Interventions: A soft insole with a semi-rigid rearfoot medial wedge was given to the treatment group, and a soft insole without corrective posting was applied to the control group.Outcome measures: The immediate and short-term effects of orthosis application on incidence of pain, pain intensity and onset time were evaluated using the 60-minutes treadmill test.Results: Immediately after wearing the foot orthosis, pain incidence reduced in the treatment group but not in the control group (P = 0.04). After two weeks, seven (58%) subjects in the treatment group and one (8%) in the control group were free of pain during the test (P = 0.01). The pain intensity score decreased significantly after orthosis application, from 35.5 to 17.2 (immediate effect, P = 0.014), then to 12.3 (short-term effect, P < 0.001).Conclusion: The rearfoot medially-wedged insole was a useful intervention for preventing or reducing painful knee or foot symptoms during running in runners with pronated foot.

Objective: To test the efficacy of calcium dobesilate (CaD) in chronic venous insufficiency (CVI). Method: Double-blind, parallel groups, placebo-controlled, multicentre trial in adult patients with symptomatic CVI and pitting oedema. Wearing of compression stockings Class II was admitted. During treatment period of eight weeks, the patients received CaD 3 x 500 mg/day or placebo. The leg volume calculation was based on a truncated cone model. Results: A total of 256 patients was randomized to treatment (dobesilate: n = 132, placebo: n = 124); the demographic and anamnestic data at admission were comparable in the two therapeutic groups. The volume of the lower calf diminished in the dobesilate group at the end of the active treatment period by -64.72 ± 111.93 cm³ (mean ± SD), independent of the concomitant usage of compression stockings versus placebo +0.8 ± 152.98 cm³ (P = 0.0002). The symptoms of pain, discomfort, heavy legs, tired legs, tingling, itching and cramps, as well as the global assessments by investigators and patients, also improved significantly (P < 0.05) better in the dobesilate group at the end of the treatment. The observed adverse events correspond to the known profile. Conclusion: Dobesilate reduces leg oedema and improves the symptoms of objectively diagnosed CVI, independent of the concomitant usage of compression stockings. [ABSTRACT FROM AUTHOR]

Most people with episodic tension-type headache (TTH) treat themselves with over-the-counter analgesics. In the absence of clear evidence of dose-related efficacy of the two most commonly used analgesics, aspirin (acetylsalicylic acid) and paracetamol (acetaminophen), this study compared two doses of each with placebo. In a double-blind, double-dummy, randomized parallel-groups comparative trial, 638 consenting subjects aged 16-65 years with episodic TTH (but not migraine) by IHS criteria were recruited from the UK general population by advertisement. They treated one episode of moderate or severe TTH with a single dose of 500 or 1000 mg aspirin, 500 or 1000 mg paracetamol or placebo. The primary objective was to compare aspirin 1000 mg with placebo, and the primary end-point was subjective pain relief (total or worthwhile) 2 h after treatment ('response'). Additionally, pain intensity on a 100-mm visual analogue scale and functional impairment were monitored regularly for 4 h and at 24 h, although rescue medication was allowed after 2 h. The analysis was of the intention-to-treat population of 542 who took treatment (all providing outcome data). Treatment groups were matched at baseline. Aspirin 1000 mg (75.7% response rate; P = 0.0009) and to a lesser extent aspirin 500 mg (70.3%; P = 0.011) and paracetamol 1000 mg (71.2%; P = 0.007), but not paracetamol 500 mg (63.8%; P = 0.104), were statistically more effective than placebo despite a high placebo-response rate (54.5%). Outcome was not affected by headache intensity at baseline. Secondary end-points including functional recovery (by median times of 4.0-13.5 h) were consistent with these findings, although a minority of subjects recorded long-duration functional impairment (37-54 h). Adverse events reported by 13.4-18.9% of subjects were mild or moderate, and transient. No safety concerns arose. [ABSTRACT FROM AUTHOR]
