Bone fractures are not uncommon in paediatric age. However, when recurrent, an underlying clinical condition must not be excluded. We describe the case of a boy aged 7 years, referred for investigation of recurrent bone fractures. Personal and family histories were unremarkable. Physical examination was normal. Almost all primary bone disorders were excluded. Additional laboratory investigations ruled out the majority of secondary causes of bone fragility. Coeliac disease (CD) serologies, however, were positive, and duodenal biopsies confirmed this diagnosis (Marsh III B). On a gluten-free diet, he suffered no more fractures and the bone mineral density improved. CD was also confirmed in his asymptomatic older brother. It is essential to diagnose CD as early as possible in order to minimise the compromise in bone health and prevent other complications of the disease. First-degree relatives should always be screened for the disease, even asymptomatic ones. © 2017 BMJ Publishing Group.

According to the Brazilian Consensus on Paracoccidioidomycosis (PCM), itraconazole is the drug of choice for treatment. However, the combination of sulfamethoxazole and trimethoprim (SMX-TMP) is most commonly used in clinical practice because of its higher availability in the public health services. The aims of this study were to evaluate the therapeutic response of patients with nonsevere chronic PCM to SMX-TMP and highlight the factors related to treatment failure. An adequate therapeutic response was defined as completely improved disease signs and symptoms after medication use for a minimum of 6 months, followed by normalized hematological and biochemical changes, radiological improvements, and negative mycological examination findings. Medical records were analyzed for 244 patients with nonsevere chronic PCM who were treated between 1998 and 2014. In total, 41.9% of the patients had PCM for ≥ 8 months. Seven (2.9%) patients were coinfected with human immunodeficiency virus (HIV). The median (25%, 75% percentiles) treatment duration was 21 (10, 25) months. Adequate treatment adherence was reported by 68.3% of patients. In addition, 73.6% of patients exhibited an adequate therapeutic response. The majority (82.6%) of patients who were treated with SMX-TMP for > 24 months displayed an adequate therapeutic response, and the frequency of adequate therapeutic response gradually decreased as the duration of treatment decreased. Treatment nonadherence (P < 0.001) and PCM-HIV coinfection (P = 0.019) were factors associated with therapeutic failure. The study results support the good efficacy of SMX-TMP. Attention should be given to PCM-HIV coinfection, emphasizing the concern of a higher risk ofPCM therapeutic failure in these patients. © 2017 by The American Society of Tropical Medicine and Hygiene.

The purpose of the present study was to correlate the acute and chronic decrease in blood pressure (BP) following resistance training (RT). 13 normotensive women (18-49 years) completed an acute whole body RT session with 3 sets of 10 repetitions at 60 % 1RM and then 8 weeks of RT as follows: 3/week, 3 sets of 8-12 repetitions maximum. Systolic (SBP) and diastolic BP (DBP) were measured up to 60 min and 24 h following RT (acute and chronic). The greatest acute decrease of SBP (108.5 ± 7.0 mmHg) and DBP (71.5 ± 6.4 mmHg) values over the 60-min period were reduced compared to pre-exercise (117.3 ± 11.7 and 79.3 ± 8.2 mmHg, respectively; p < 0.05). The chronic effect on resting BP was observed only for those presenting acute post-exercise hypotension (PEH). The change in both SBP and DBP following acute RT was correlated with the chronic change in resting SBP and DBP (r > 0.5; p ≤ 0.05). The change in 24 h BP after acute RT was correlated with the chronic reduction in SBP (r = 0.74) and DBP (r = 0.80). The magnitude of PEH is a promising candidate for the prediction of individual BP-related training efficacy. © Georg Thieme Verlag KG.

Stress fractures are frequently underdiagnosed and undertreated despite being common in sports. Early diagnosis is crucial; therefore, a high index of clinical suspicion is required. Complementary examinations are essential for diagnosis and follow-up. The authors report a clinical case of a young adult triathlon athlete referring mechanical pain in the rear left foot, with 2 weeks' progression. An earlier increase in daily training intensity was recorded. Complementary examinations confirmed a calcaneal fatigue fracture. Immobilization and no weight bearing were introduced for an initial period of 4 weeks, and the rehabilitation process was started. Progressive weight bearing was introduced between fourth and eighth weeks. Sports activity started at the 12th week. Boundaries to sports activity were eliminated by the 24th week, without pain or functional limitation. Repetitive overload to the heel and intense axial weight bearing in association to repetitive concentric/eccentric gastrocnemius contraction are related to calcaneal stress fracture, the second most common stress fracture in the foot. Calcaneal stress fractures can be adequately treated with activity modification, without casting or surgical intervention. When in the presence of bilateral stress fractures, metabolic and nutritional issues must be considered. The case report highlights the importance of sports medicine examination for detecting intrinsic and extrinsic fatigue fracture risk factors. © 2016 Wolters Kluwer Health, Inc.

The isothermal and non-isothermal ageing of an Al-2.4 wt% Cu alloy have been studied using X-ray diffraction analysis and differential scanning calorimetry (DSC) at different heating rates. Quantitative metallography methods have been applied to measure the corresponding transformed volume fractions at various temperatures and times of precipitation. The variation of the heating rate using DSC technique has allowed us to calculate two kinetics parameters of precipitation which are the Avrami exponent and the activation energy of the process using Kissinger, Ozawa and Bosswell methods. These parameters are similar to those found for the precipitation reaction of θ′ and θ (Al2Cu) phases. © 2011 Elsevier B.V. All rights reserved.

Various physical properties of the cubic perovskite-type oxide BiScO 3 have been investigated using the pseudo-potential plane-wave (PP-PW) method based on the density functional theory (DFT). The computed equilibrium lattice parameters agree well with the available theoretical data. The elastic constants and their pressure dependence are predicted using the static finite strain technique. A set of isotropic elastic parameters and related properties, namely bulk and shear moduli, Young's modulus, Poisson's ratio, average sound velocity and Debye temperature are numerically estimated in the framework of the VoigtReussHill approximation for BiScO3 polycrystalline aggregate. The analysis of the site-projected l-decomposed density of states, charge transfer and charge density shows that bonding is predominantly of ionic nature. We distinguish hybridization between Sc-d states and O-p states in the valence bonding region. Through the quasi-harmonic Debye model, in which the phononic effects are considered, the thermal effect on the lattice constant, bulk modulus, heat capacities and thermal expansion coefficient is calculated. © 2011 Elsevier Ltd.

The structural, elastic, electronic, optical and thermal properties of the semiconductor perovskite CsPbCl3 were investigated using the pseudo-potential plane wave (PP-PW) scheme in the frame of generalized gradient approximation (GGA) and local density approximation (LDA). The computed lattice constant agrees reasonably with experimental and theoretical ones. The CsPbCl3 crystal behaves as ductile material. The valence bands are separated from the conduction bands by a direct band gap RR. We distinguished hybridization between Pb-p states and Cl-p states in the valence bonding region. Under compression at P=30 GPa, this material will have a metallic character. The thermal effect on the lattice constant, bulk modulus, Debye temperature and heat capacity CV was predicted using the quasi-harmonic Debye model. To the authors knowledge, most of the studied properties are reported for the first time. © 2011 Elsevier B.V. All rights reserved.

The structural, elastic, electronic, optical and thermodynamic properties of the cubic perovskite-type hydride KMgH3 have been investigated using pseudo-potential plane-wave method based on the density functional theory. Computed equilibrium lattice constant agrees well with the available experimental and theoretical data. The elastic constants and their pressure dependence are predicted using the static finite strain technique. A linear pressure dependence of the elastic stiffnesses is found. A set of isotropic elastic parameters and related properties, namely bulk and shear moduli, Young's modulus, Poisson's ratio, average sound velocity and Debye temperature are numerically estimated in the frame work of the Voigt-Reuss-Hill approximation for KMgH3 polycrystalline aggregate. The analysis of the site-projected l-decomposed density of states and charge density shows that the bonding is predominantly of ionic nature. Through the quasi-harmonic Debye model, in which the phononic effects are considered, the temperature effect on the lattice constant, bulk modulus, heat capacity and Debye temperature is calculated. © 2010 Elsevier Masson SAS.

The aim of this study was to determine the prevalence and to identify the risk factors associated with Leptospira spp. infection in technified pig farms in the state of Alagoas, Brazil. To compose sample for the prevalence study, 342 pigs were used (312 sows and 30 boars) proceeding from seven swine farms distributed in five districts of the state of Alagoas, Brazil. The infections serological diagnosis was performed by microscopic agglutination test. The risk factors analysis was performed using research questionnaires consisting of objective questions related to the breeder, the general characteristics of the property, and the productive, reproductive and sanitary management. Prevalence of 16.1% (55/342) of pigs seropositive was obtained. The associated risk factors were not performing quarantine (P = 0.003, OR = 5.43, CI = 1.79-16.41) and the use of artificial insemination (P = 0.023, OR = 3.38, CI = 1.18-9.66). A significant association of sow infection with the increased number of stillborn and mummified foetuses was found, as well as with the increased frequency of oestrus recurrence and the increased weaning-to-oestrus interval of seropositive sows. One might state that Leptospira spp. infection is disseminated in technified pig farms in the State of Alagoas, favouring reproductive failures and the impairment of zootechnical performance in these properties. The risk factors identified in this study are facilitators in the infecting agent dissemination and should be adjusted to control the disease in the herds studied.
