Resistance training with slow speed of movement is better for hypertrophy and muscle strength gains than fast speed of movement.

Repetition speed is an important variable during resistance training. However, the effects of different speeds on the muscular strength and hypertrophy in isotonic resistance training are not clear. The study compared fast speed with slow speed of isotonic resistance training on muscular strength and hypertrophy in well-trained adults. Twelve healthy adults were randomly assigned into two groups: fast speed (FS) and low speed (SS). Muscle hypertrophy was measured by an ultrasound examination of the cross-sectional area of the brachial biceps muscle. Muscular strength was verified by 1 RM test. To check the possible differences in strength and hypertrophy between pre and post training and between groups there were compared by two-way ANOVA for repeated measurements and the effect size (ES) was calculated. Improvement in the cross-sectional area (P=0.019) and muscular strength (P=0.021) in the SS group between pre and post training was verified. The SS group had bigger effect sizes than FS group for hypertrophy and strength from pre to post training. SS training was more effective to improve hypertrophy and muscle strength in well-trained adults.Univ Fed Sao Paulo, Grp Studies & Res Exercise Physiol, Santos, SP, BrazilPraia Grande Coll, Grp Studies Sci Phys Educ, Praia Grande, SP, BrazilUniv Fed Sao Paulo, Dept Human Movement Sci, Santos, SP, BrazilUniv Fed Sao Paulo, Grp Studies & Res Exercise Physiol, Santos, SP, BrazilUniv Fed Sao Paulo, Dept Human Movement Sci, Santos, SP, BrazilWeb of Scienc

Intussusception of cecal appendix

The authors report the case of a child with the diagnosis of appendiceal intussusception and describe the clinical, ultrasonographic, colonoscopic and surgical aspects. The authors discuss these aspects based on a review of recent literature

Ultrasonography in the diagnosis of acute appendicitis

Objective: To evaluate the role of sonography in diagnosis ofacute appendicitis, with an emphasis on early evolution cases.Methods: From 240 cases with the diagnosis of appendicitis, aretrospective study of 149 patients submitted to appendicectomyat the Hospital Israelita Albert Einstein, in 2002, was carried out.The appendix of these 149 patients was visualized in apreoperative sonography and the diagnosis was confirmed byhistological examination. Patients were distributed into twogroups - initial and advanced - according to the measure of thelargest external diameter of the appendix. The statistical dataanalysis included demographic information (sex and age) anddirect and indirect signs of acute appendicitis. Results: Therewere more cases of acute appendicitis in the groups aged 10-30years, mean age of 18.3 years in the initial group and 26.4 yearsin the advanced group. There was no statistically significantdifference regarding sex. The advanced group presented 4.5%of false-positive results and the initial group, 23.1%. Among thedirect signs, non-compressibility of the appendix stood out andwas observed in more than half cases; with regard to indirectsigns, hyperechogenicity of periappendiceal tissues wasobserved in up to 75% of cases in both groups. Conclusion: Therewas a statistically significant difference in false-positive cases,which were more often observed in the initial group. Therefore,sonographic follow-up is recommended in these cases

Differential diagnosis of calf pain by ultrasonography

This paper aims to evaluate the recent and numerous applications of ultrasonography in the differential diagnosis of conditions that affect the popliteal fossa and lower limbs, resulting in calf pain. Popliteal cysts and their ruptures, aneurysms, hematomas, cellulitis, abscesses, soft tissue tumors and other fluid collections are easily identified by this technique. Moreover, post-trauma and inflammatory conditions affecting muscles and tendons, muscle necrosis, deep venous thrombosis and superficial thrombophlebitis are very well demonstrated by the ultrasonographic screening

Ultrasonography evaluation of tendon thickness in hemodialysis patients

Objective: To evaluate tendon thickness at ultrasonography (US)imaging in long-term dialysis recipients. Methods: Twenty chronicdialysis recipients underwent US examination to evaluate tendonthickening, including that of the supraspinatus, subscapularis, biceps,triceps, quadriceps, patellar and calcaneal tendons with no partial orcomplete lesions. These patients were compared with 22asymptomatic patients and the rejection of null hypothesis was 5%(Student’s t test, p < 0.05). Results: Statistically significant thickeningwas found in the supraspinatus, subscapularis, triceps and right bicepstendons. The statistical analysis of the other tendons was notsignificant. Conclusion: Amyloid protein deposition in tendons wasnot uniform; the current study shows a predominance of thisoccurrence in tendons in the upper limbs

Urban insecurity and fear of crime in people suffering from patients with mental disorders: preliminary results of a multicentric Italian study = Insicurezza percepita e paura del crimine in persone affette da disturbi mentali: Uno studio in 24 Centri di Salute Mentale

Aims. To assess in a sample of people with mental disorders: 1) fear of crime and perceived insecurity; 2) the association between fear of crime and insecurity; 3) the incidence of crimes. Methods. Twenty-four Italian mental health centres have been invited to participate in the study from the network of the Early Career Psychiatrists' Committee of the Italian Psychiatric Association. In each participating centre, the first 20 patients consecutively accessing the mental health centre between February and April 2011 have been recruited. All patients have been assessed using validated assessment tools. Results. The final sample consists of 426 patients. They are mostly female (70.1%), with a mean age of 45 years (±13.5), and with a good level of education. Fifty-two percent of patients have a diagnosis of mood disorders, and 37.8% on anxiety spectrum disorders. About half of the sample declares that the most prominent feeling toward life is uncertainty. Almost all patients report to have at least one big fear, with the most frequently report being: 1) loss or death of a loved one (41.2%); 2) financial constraint (28.4%); 3) physical or mental health problems (26.5%). Discussion and conclusions. Our results show the presence of a common sense of uncertainty among patients, probably as a result of the historical moment we are facing. It is reasonable that this attitude toward life can have a detrimental impact on patients' psychological and physical wellbeing, contributing to high levels of distress. Further studies are needed in order to clarify the possible relationship between fears, uncertainty and mental disorders
