    The behavior and treatment of coxa vara and pseudarthrosis of the proximal femur secondary to sepsis is not well described. The aim of this study is to describe the pathoanatomy for coxa vara and pseudarthrosis in postseptic hips, evaluate progression of neck shaft angle (NSA), and discuss treatment. This is a retrospective case series of 20 patients (21 hips). There were 11 hips with predominant avascular necrosis of the capital femoral epiphysis without pseudarthrosis (type 1) and 10 with pseudarthrosis (type 2). The interobserver κ value was 0.79. There was a decrease in NSA from 110.3° to 99.3° during an average follow-up duration of 5.2 years (range: 2-14 years). The average change in NSA between the initial presentation and the final follow-up was 5.5° in type 1 and 17.1° in type 2. Nine patients underwent a surgical intervention. In cases where subtrochanteric valgus osteotomy was performed, the mean preoperative NSA was 94° and the mean NSA at the final follow-up was 128°; all operated pseudarthroses healed without bone grafting. Acetabuloplasty is not necessary in most cases.

    We addressed the issue of the design of mechanical coxa joints based on three-degree-of-freedom spherical parallel manipulators using the parameter statistics optimum method based on index atlases. The coxa joints have the advantages of high payload, high accuracy, and good technological efficiency. The first step of the design and prototyping used in this paper develops the direct and inverse displacement equations from the layout feature of the mechanical coxa joints. Then, the shapes of a constant-orientation workspace of the mechanical coxa joints are described, and the effects of the design parameters on the workspace volume are studied quantitatively. The next step deals with the graphical representation of the atlases that illustrates the relationship between performance evaluation index and design parameters based on the kinematics and torque analysis of the mechanical coxa joints. Finally, the geometric parameters of the coxa joints are obtained by the parameter statistics optimum method based on the index atlases. Considering assembly conditions, the design scheme of the mechanical coxa joints is developed, which provides a theoretical basis for the application of the mechanical coxa joints.

    A series of experimental studies has been carried out to study the kinetic of accumulation and human exposure to trace metals using the bloody cockle (Anadara senilis) as a model organism. This species is of ecological and economic importance in Ghana and other parts of Western Africa where they are commonly found. Trace metals mainly Mn, Co, Zn, Ag and Cd were studied using both laboratory mesocosm and field investigations. The laboratory experiments were carried out through the use of radiotracers: "5"4Mn, "5"7Co, "6"5Zn, "1"1"0"mAg and "1"0"9Cd, to study the kinetics of metal accumulation in the cockle through 2 different exposure pathways. The variability of metal bioaccumulation in the bloody cockle as a function of environmental and physiological conditions was also investigated. Metal subcellular fractionation, tissue distribution and simulating human digestion through the use of in vitro methodology were incorporated to understand the processes governing metal accumulation and human health risk assessment from the consumption of contaminated shellfish. Following a 2-hour single feeding and a 28-day depuration period, metals ingested with food (Isochrysis galbana or Skeletonema costatum) were moderate to highly assimilated in the cockle (11 to 72%), although, the degree of assimilation was dependant on the type of phytoplankton strain, the studied metals and the size of the cockle. Retention of assimilated metals was metal dependant being described as weak for Ag (T_b_1_/_2 of 2 to 6 days), moderate for Mn, Co and Zn (T_b_1_/_2 of 13 to 47 days) and strong for Cd (T_b_1_/_2 ≥ 97 days). Over a 28-day dissolved exposure period, bioconcentration kinetics of metals in two size classes of bloody cockles studied under different exposure conditions (high and low salinity) generally were best described by a saturation model assuming an apparent steady state concentration. The results showed strong variability on the kinetics of metal uptake among different size

    In total hip arthroplasty (THA) of hips with coxa vara, the femoral stems might be inserted in a varus alignment. To avoid varus insertion, we designed a technique, which we termed "trochantoplasty." In this procedure, the medial half of the greater trochanter was removed during THA. We evaluated 30 patients (31 hips) who had coxa vara deformity and underwent THA using trochantoplasty at the mean follow-up of 5 years (range, 3-9 years). All stems were inserted in the neutral position. One Vancouver type 1 periprosthetic femoral fracture occurred after a fall at postoperative 2 months. At the latest follow-up, the mean power of abductor was 4.3 (range, 3-5). Four patients had moderate limp whereas 26 patients had slight limp. The abduction at 90° flexion ranged from 15° to 45° (mean, 35°). There was no revision. All prostheses had bone-ingrown stability without any detectable wear or osteolysis. The mean Harris hip score was improved from 66.9 to 89.4 points. Trochantoplasty can be used to avoid varus insertion of the femoral stem while performing THA in patients with coxa vara deformity without compromising the abductor mechanism.

    Background. This paper reports three children with short stature: developmental coxa vara unilateral in the first case and bilateral in the other two; somewhat squared and ''ovoid'' vertebral bodies in the first patient, and normal to slightly tall vertebral bodies in the third; metaphyseal changes in some long tubular bones including bone fragments similar to the corner fractures seen in child abuse in all three patients. Materials and methods. The first and second patients were sisters; their mother, also quite short, had surgical procedures in early life for bilateral ''coxa vara''; their brother, also of short stature, had bilateral coxa valga with otherwise normal femoral heads and necks, and mild metaphyseal changes associated with two minute ''corner fractures'' in the proximal metaphysis of the left tibia. Results. A review of reported cases of developmental coxa vara associated with spondylometaphyseal dysplasia revealed that simulated corner fractures were present in most instances. (orig.)

    Full Text Available Lumbosacral spine and hip joints is a complex physiological functions of the co-operation of a large number of anatomical structures. Lesions of the links in the system can mutually afflict each other. Combined pathology of the hip and lumbosacral spine is called hip-spine syndrome, or coxa-vertebral syndrome. Symptoms of the joint and spine are very similar and only a careful examination and clinical examination may find the differences. As the disease progresses the hip increases the restriction of movement, there is a contracture of the limbs in a vicious position, which leads to an increase in tilt of the pelvis, increased lumbar lordosis and to functional shortening of limbs on the affected side. This gives rise to functional impairment, and then strain the joints of his spine and disease - osteochondrosis and scoliosis. After the successful operation of total hip replacement is often progressive clinical lesions of vertebral segment, which is manifested pain and is often offset by the results of arthroplasty as the restoration of movement in the hip joint, and the change in length limb after arthroplasty leads to rupture formed a functional stereotype change in the mobility of the lumbar spine, pelvis regression bias that causes the dynamic compression spinal nerve root. Depending on the duration of the existence, severity and nature of changes in the pelvic girdle is suitable correction of equipment replacement surgery, including, for example, in some cases, deliberate shortening or lengthening the preservation of the lower extremity, offset change, etc.

    Congenital coxa vara (CCV) is a rare hip condition with few long-term studies. The purpose of this study was to assess clinical, radiographic, and functional outcomes after operative and nonoperative treatment of CCV, assess reliability of radiographic parameters, and investigate risk factors for recurrence after surgery. Retrospective review was performed of all CCV patients treated at 1 institution from 1980 to 2010. In addition, patients were recalled for additional follow-up x-rays, modified Harris Hip Score (mHHS), and gait analysis. Radiographic measurements [neck-shaft angle (NSA), head-shaft angle (HSA), Hilgenreiner-epiphyseal angle (HEA), and femoral neck length (FNL)] were assessed for reliability using intraclass correlation coefficients. Multivariate analysis was performed to identify risk factors for recurrence after surgery. Forty-six hips in 32 patients were reviewed. Mean age at presentation was 5.4±4.9 years. Mean follow-up was 11.8±5.8 years. Valgus proximal femoral osteotomy was performed in 27 hips (20 patients). Initial deformity was greater in the operative group (NSA 90±17 degrees, HEA 68±19 degrees) versus nonoperative patients (NSA 122±19 degrees, HEA 34±14 degrees) (PNSA occurred in only 21%. In contrast, 56% of operative hips showed decreased FNL growth rates. Interobserver reliability was excellent for HEA (0.98), NSA (0.90), and FNL (0.89), and good for HSA (0.79). Repeat osteotomy was performed in 6 cases (22%). No significant predictors for recurrence were identified. At long-term follow-up for recalled patients, 72% had significantly abnormal gait, and 50% had fair-poor functional outcomes (mHHSNSA are the most reliable radiographic measurements of proximal femoral deformity in CCV. Recurrence is not uncommon, but no predictors were identified. Many patients have persistent gait abnormalities and functional impairment at long-term follow-up, regardless of prior treatment.

    Differences in the breadth of the pelvis among modern human populations and among extinct hominin species have often been interpreted in the light of thermoregulatory adaptation, whereby a larger pelvic girdle would help preserve body temperature in cold environments while a narrower pelvis would help dissipate heat in tropical climates. There is, however, a theoretical problem in interpreting a pattern of variation as evidence of selection without first accounting for the effects of neutral evolutionary processes (i.e., mutation, genetic drift and migration). Here, we analyse 3D configurations of 27 landmarks on the os coxae of 1494 modern human individuals representing 30 male and 23 female populations from five continents and a range of climatic conditions. We test for the effects of climate on the size and shape of the pelvic bone, while explicitly accounting for population history (i.e., geographically-mediated gene flow and genetic drift). We find that neutral processes account for a substantial proportion of shape variance in the human os coxae in both sexes. Beyond the neutral pattern due to population history, temperature is a significant predictor of shape and size variation in the os coxae, at least in males. The effect of climate on the shape of the pelvic bone, however, is comparatively limited, explaining only a small percentage of shape variation in males and females. In accordance with previous hypotheses, the size of the os coxae tends to increase with decreasing temperature, although the significance of the association is reduced when population history is taken into account. In conclusion, the shape and size of the human os coxae reflect both neutral evolutionary processes and climatically-driven adaptive changes. Neutral processes have a substantial effect on pelvic variation, suggesting such factors will need to be taken into account in future studies of human and fossil hominin coxal variation.

    A new tool for skeletal sex estimation based on measurements of the human os coxae is presented using skeletons from a metapopulation of identified adult individuals from twelve independent population samples. For reliable sex estimation, a posterior probability greater than 0.95 was considered to be the classification threshold: below this value, estimates are considered indeterminate. By providing free software, we aim to develop an even more disseminated method for sex estimation. Ten metric variables collected from 2,040 ossa coxa of adult subjects of known sex were recorded between 1986 and 2002 (reference sample). To test both the validity and reliability, a target sample consisting of two series of adult ossa coxa of known sex (n = 623) was used. The DSP2 software (Diagnose Sexuelle Probabiliste v2) is based on Linear Discriminant Analysis, and the posterior probabilities are calculated using an R script. For the reference sample, any combination of four dimensions provides a correct sex estimate in at least 99% of cases. The percentage of individuals for whom sex can be estimated depends on the number of dimensions; for all ten variables it is higher than 90%. Those results are confirmed in the target sample. Our posterior probability threshold of 0.95 for sex estimate corresponds to the traditional sectioning point used in osteological studies. DSP2 software is replacing the former version that should not be used anymore. DSP2 is a robust and reliable technique for sexing adult os coxae, and is also user friendly. © 2017 Wiley Periodicals, Inc.

    In coastal ecosystems where bivalves are often exposed to metal contamination, dietary exposure has been recognised as a dominant uptake pathway of trace metals in bivalves. The present study employed radiotracers ("6"5Zn and "1"1"0"mAg) to assess the assimilation efficiency (AE) of the two elements in Bloody cockles (Anadara senilis) from Narkwa Lagoon, Ghana. AE is an important parameter in determining bioavailability of trace elements from food. Zn and Ag bioavailabilty was assessed using single-feeding approach, followed by a 28–day depuration period, with two species of phytoplankton (Isochrysis galbana and Skelotonema costatum) used as food, and two different size groups of Bloody Cockles. Results indicate that AE of "6"5Zn and "1"1"0"mAg were influenced by the phytoplankton species used as food whereas, for both algal species, AE increased slightly with increasing cockle body size. Once taken up, "6"5Zn was relatively strongly retained in cockle’s flesh (biological half-live: ≈40 days) whereas "1"1"0"mAg was rapidly released (biological halflive: ≈5 days). A complementary experiment -using subcellular partitioning and in vitro digestion method- was performed to provide additional information on the proportion of "6"5Zn and "1"1"0mAg in the bloody cockle that is available for transfer to next trophic levels. Overall, this work highlighted that trace metal accumulation in marine filter feeders does depend on the metal bioavailability in food as well as on other biological factors, such as body size.

    Full Text Available Hand, foot, and mouth disease (HFMD has been emerging as an important public problem over the past few decades, especially in Asian and Pacific regions. A national program on EV71 vaccine development against HFMD was initiated in China, in 2008, which called for a need for seroepidemiological study for the target population.This was a retrospective study conducted in Jiangsu Province, in October, 2010. We measured the neutralizing antibodies against EV71 and CoxA16 in a cohort of infants aged of 2, 7, 12, and 27-38 months and their mothers just before delivery. Series sera samples from 975 infants and 555 mothers were collected and analyzed. Questionnaires on the history of HFMD were completed in the survey. A total of 143 HFMD cases were collected, but only 11.2% were reported to the National Infectious Disease Information Management System. The level of maternal antibody titers decreased dramatically during the first 7 month and remained at a relatively low level thereafter. But it increased significantly from month 12 to months 27-38. The accumulate incidence density of HFMD demonstrated a significant increase after 14 months of age, resulting in a accumulate incidence density of 50.8/1000 person-years in survey period. Seropositivity of EV71 antibody in infants at the age of 2 months seems to demonstrate a protective effect against HFMD.High seropositive rate of EV71 and CoxA16 antibody was found in prenatal women in mainland China, and there is a need to enhance the HFMD case management and the current surveillance system. We suggest that infants aged between 6 to 14 months should have the first priority to receive EV71 vaccine.

    1990-01-01

    Full Text Available The condition of certain neglected structures and their possible importance to the classification of the family Tabanidae are studied. The front coxae are considered as belonging to two types: 1 short and robust; 2 long and slender. The posterior edge of the meso-katepimeron presents two conditions: 1 without projection, 2 with backward projection. Similar conditions are found in the meso-Katepisternum, but with intermediate conditions. These characters are discussed in relation to the system proposed for the family by Mackerras. Conditions 1 and 2 of the former two structures separate, respectively, the Pangoniinae and Scepsidinae from the Chrysopsinae and Tabaninae. Condition 2 of the third structure seems to be developing independently in different groups of Tabaninae, with varying degrees of development.

    By means of 120 scintigrams and 42 arteriographs it was shown that blood vessel tamponade caused the development of femoral head necrosis. Native radiography, scintiscanning and arteriography rendered possible an early diagnosis of the disease. The temporal course of the disease could be controlled. The site of the necrosis and thus the prognosis of the disease are dependent on extent and localization of the disturbed blood supply.

    Full Text Available OBJETIVOS: Comparar os resultados dos testes de Dedos ao Chão e Elevação dos MMII em Extensão por meio da fotogrametria, verificar a concordância entre os achados do ângulo do quadril entre os dois testes e avaliar a confiabilidade intra e interavaliadores do procedimento de análise fotogramétrica. MÉTODO: Os testes foram aplicados em 35 sujeitos saudáveis do sexo masculino (média de 23 anos de idade ± 3, 170 cm de altura ± 4 e 68 Kg ± 11, que foram divididos em dois grupos com base na classificação dos testes. Marcadores superficiais foram colocados em referências ósseas para traçar os ângulos do quadril, tóraco-lombar, perna, joelho e tíbio-társico. Testou-se a confiabilidade do procedimento de análise fotogramétrica dos ângulos mensurados por dois avaliadores. RESULTADOS: Para o ângulo do quadril houve diferenças significativas entre os grupos de flexibilidade, nos dois testes, sendo que o ângulo foi menor nos sujeitos com flexibilidade reduzida. Houve uma diferença significativa de 22,8% entre a classificação designada pelos dois testes. Entretanto, o ângulo do quadril obteve altos índices de concordância entre os testes (ICC: 0,89 e diferença média de -0,85º. Os procedimentos de fotogrametria apresentaram altos índices de confiabilidade tanto intra quanto interavaliadores (ICC variando de 0,94 a 0,99. CONCLUSÃO: Os testes apresentaram diferenças na classificação de flexibilidade dos sujeitos. Entretanto, quando o ângulo do quadril foi considerado, houve alta concordância entre os resultados dos testes. Os procedimentos de análise fotogramétrica foram reprodutíveis tanto intra quanto interavaliadores, constituindo uma ferramenta útil de análise para os testes em questão.OBJECTIVE: To compare the results from fingertip-to-floor and straight leg raise tests by means of photogrammetry, investigate the concordance of hip angle findings between the two tests and evaluate the intra and inter-examiner reliability of the photogrammetric analysis procedure. METHOD: The tests were applied to 35 healthy male subjects (mean age 23 ± 3.4 years, height 170 ± 4 cm and weight 68 ± 11 kg. The subjects were divided into two groups on the basis of the test classifications. Surface markers were placed on bone references in order to calculate the hip, thoracolumbar, leg, knee and tibiotarsal angles. The reliability of the photogrammetric analysis procedure on the angles measured by two examiners was tested. RESULTS: For the hip angle, there were significant differences between the flexibility groups in both tests, and subjects with reduced flexibility had lower angles. There was a significant difference (22.8% between the classifications designated by the two tests. However, the hip angle showed high levels of concordance between the tests (ICC: 0.89 and mean difference of -0.85º. The photogrammetric procedures presented high reliability rates, both for intra and inter-examiner (ICC ranging from 0.94 to 0.99. CONCLUSION: The tests presented differences in the classification of the subjects' flexibility. However, considering the hip angle, there was high concordance between the test results. The photogrammetric analysis procedures were reproducible, both for intra and for inter-examiner measurements, thus making this a useful analysis tool for the tests in question.

  5. Notes on the Nest Architecture of Halictus senilis (Eversmann) in Southeast Kazakhstan (Hymenoptera, Halictidae)

    2006-01-01

    Four nests of Halictus senilis (Eversmann) were excavated near Chimkent, southeast Kazakhstan. The nest of H. senilis was similar in structure to nests of the other species of Halictus s. s., i.e., each cell directly, not by means of lateral, connected to the main burrow. On the other hand, the deviation from the typical nest structure of Halictus was found. The coexistence of delayed eusocial and solitary nests was suggested in this species.

    Two cases of lenticular opacity were discussed from the view point of exposure dose of A-bomb radiation. Case 1: female, 22 year and 5 months old when she was exposured to A-bomb radiation. The presumed exposure dose was 482.0 rad. Cataract due to A-bomb radiation. Case 2: female, 21 years and 6 months old when she was exposured to A-bomb radiation. The presumed exposure dose was more than 1,000 rad. Cataract due to A-bomb radiation and incipient cataract senilis. It was reported here that there was a marked difference in opacity findings of cataract due to A-bomb radiation in accordance with difference in exposure dose of radiation. It was also presumed from the findings of incipient cataract senilis that with increasing exposure dose, the aging phenomenon was promoted.

    2009-01-01

    Full Text Available Background /Aim. Cataract is a structural, biochemical and optical change in the eye lens, which changes transmission and refraction of light rays reducing keenness and clarity of a figure on the retina. Its occurrence is highest in older people, over the age of 65 (45.9%, thus a certain degree of opacification exists practically in all people over the 70. Our research was directed to measuring of lipid peroxidation products in cataract lenses involved in early stages of cataractogenesis through oxidative stress and in the development of mature cataract. Methods. Clinical and biochemical research was carried out in 101 patients with cataract, 46 women and 55 men. The average age of the group was 72.47 (ґ = 7.98. According to the cataract maturity degree the patients were classified into two groups as follows: cataracta senilis incipiens (n = 41 and cataracta senilis matura (n = 60. Measuring of diene conjugates was carried out by spectrophotometer. Fluorescent lipid peroxidation products were measured by a spectrofluorophotometer, and malondialdehyde (MDA concentration was measured by colorimeter as a product of a reaction with thiobarbituric acid (TBA. Result. Significantly higher diene conjugated concentration in lenses was measured in the patients with the diagnosis cataracta senilis incipiens (p < 0.001 as well as the intensity of fluorescent iminopropens (p < 0.001. Significantly higher MDA concentration in lens (p < 0.001 was measured in the patients with cataracta senilis matura. Conclusion. The lens structure changes caused by lipid peroxidation can, with other risk factors present, influence the occurrence and development of mature cataract. Some cataract types show different lipid peroxidation intensity with the most distinct changes in cataract which started as corticonuclear.

    Enterovirus 71 (EV71) and coxsackievirus A16 (CoxA16) are main pathogens of hand-foot-and-mouth disease, occasionally causing aseptic meningitis and encephalitis in tropical and subtropical regions. Kalanchoe gracilis, Da-Huan-Hun, is a Chinese folk medicine for treating pain and inflammation, exhibiting antioxidant and anti-inflammatory activities. Our prior report (2012) cited K. gracilis leaf extract as moderately active against EV71 and CoxA16. This study further rates antienteroviral potential of K. gracilis stem (KGS) extract to identify potent antiviral fractions and components. The extract moderately inhibits viral cytopathicity and virus yield, as well as in vitro replication of EV71 (IC50 = 75.18 μg/mL) and CoxA16 (IC50 = 81.41 μg/mL). Ethyl acetate (EA) fraction of KGS extract showed greater antiviral activity than that of n-butanol or aqueous fraction: IC50 values of 4.21 μg/mL against EV71 and 9.08 μg/mL against CoxA16. HPLC analysis, UV-Vis absorption spectroscopy, and plaque reduction assay indicate that eupafolin is a vital component of EA fraction showing potent activity against EV71 (IC50 = 1.39 μM) and CoxA16 (IC50 = 5.24 μM). Eupafolin specifically lessened virus-induced upregulation of IL-6 and RANTES by inhibiting virus-induced ERK1/2, AP-1, and STAT3 signals. Anti-enteroviral potency of KGS EA fraction and eupafolin shows the clinical potential against EV71 and CoxA16 infection. PMID:24078828

    Due to waning levels of maternal antibodies (measles; enterovirus 71, EV71; and coxsackievirus A16, CoxA16), some infants may lose protection against infection prior to vaccination. Using a longitudinal design, we examine how maternal antibody levels evolve over time in infants prior to vaccination. In 2013-2014, we collected sera at ages 0, 3 and 6months from infants. We assayed for levels of measles IgG antibody (717, 233 and 75 sample sera tested at months 0, 3 and 6, respectively), and neutralizing antibodies for EV71 and CoxA16 (225, 217, and 72). Demographic and health information were collected, and a linear mixed model (LMM) was used to describe antibody levels over time. Pre-vaccination monotonic antibody decreases were observed for measles (1410, 195 and 22mIU/ml, p<0.001), EV71 (1:19.9, 6.3 and 4.5, p<0.001) and CoxA16 (1:16.3, 5.9, and 4.5, p<0.001). At 6months of age, only 2.7% (95%CI, 0.6-8.3), 6.8% (95%CI, 2.7-14.4) and 5.6% (95%CI, 1.9-12.7) of infants were antibody positive for measles, EV71 and CoxA16, respectively. LMM findings indicated that infants with higher antibody titers at birth experienced a greater loss of antibody level. An infection rate of 1.3% (95%CI, 0.1-6.1) was reported for both EV71 and CoxA16. Further modifications of vaccination strategies for measles, earlier vaccination for EV71 infection, and deployment of a CoxA16 vaccine need to be considered to limit infection among the very young.

  18. Is phenotypic plasticity a key mechanism for responding to thermal stress in ants?

    Science.gov (United States)

    Oms, Cristela Sánchez; Cerdá, Xim; Boulay, Raphaël

    2017-06-01

    Unlike natural selection, phenotypic plasticity allows organisms to respond quickly to changing environmental conditions. However, plasticity may not always be adaptive. In insects, body size and other morphological measurements have been shown to decrease as temperature increases. This relationship may lead to a physiological conflict in ants, where larger body size and longer legs often confer better thermal resistance. Here, we tested the effect of developmental temperature (20, 24, 28 or 32 °C) on adult thermal resistance in the thermophilic ant species Aphaenogaster senilis. We found that no larval development occurred at 20 °C. However, at higher temperatures, developmental speed increased as expected and smaller adults were produced. In thermal resistance tests, we found that ants reared at 28 and 32 °C had half-lethal temperatures that were 2 °C higher than those of ants reared at 24 °C. Thus, although ants reared at higher temperatures were smaller in size, they were nonetheless more thermoresistant. These results show that A. senilis can exploit phenotypic plasticity to quickly adjust its thermal resistance to local conditions and that this process is independent of morphological adaptations. This mechanism may be particularly relevant given current rapid climate warming.

  1. Primary abductor hip contracture as diagnostic, prognostic and therapeutic problem in child hip pathology

    Directory of Open Access Journals (Sweden)

    2007-01-01

    Full Text Available Coxa obliqua represents a special functional entity in the pathology of the child hip. Authors have confirmed the results of S.L. Weissman and B. Strinovic which claimed that the abductor contracture of the hip was a primary congenital condition that developed as a result of intrauterine malposition, leading later to the contralateral adductor contracture. Critical period for the development of complications was between 6 and 8 month after birth, adductor contracture might keep persisting together with the development of acetabular dysplasia, and later on with ipsilateral subluxation. This malformation has usually been diagnosed within 3 and 6 months of age. It could be connected with some other signs of malposition, such as plagiocephaly, torticollis or infantile thoracic C scoliosis. For the diagnosis of coxa obliqua, the examination of hips in the prone position was very important and the ultrasonic and radiological examinations were crucial. The applied treatment used to be exclusively physical rehabilitation. Wide diapering has been contraindicated. In this study, we included 2,500 newborns, 1,300 boys and 1,200 girls (5,000 hips. In 22 cases of coxa obliqua (10‰, the excellent results were obtained in 96% of cases. In two unsuccessfully treated cases, a contralateral dysplasia developed, and in one untreated, subluxation. The authors are advocating a systematic and early detection and treatment of the primary coxa obliqua. .

  7. Formulación de absolutos en teología moral: tres casos

    Directory of Open Access Journals (Sweden)

    Pablo Concha

    2008-01-01

    Full Text Available En moral la formulación de un absoluto equivale al establecimiento de una norma absolutamente vinculante; es decir una norma que obliga en toda circunstancia y a todo agente, sin quedar condicionada por la intención con que este hubiere realizado el comportamiento normado. Se trata, generalmente, de normas positivas que no rigen comportamientos, sino a la naturaleza humana, en cuanto tal. Por ejemplo, los principios de la Ley Mosaica: "ama a tu Dios y a tu próximo. Pero, sobre todo, estamos ante un absoluto moral, cuando escuchamos el llamado que Cristo hace a su seguimiento. Un absoluto muy particular, porque fácilmente se descubre que constituye un imposible. En otras palabras, que, aquí, Cristo pide lo que solo Él puede dar y, de hecho da. Otro absoluto, de otra naturaleza, son los absolutos negativos; es decir, no los actos que deben hacerse siempre, sino los que no pueden hacerse nunca: los actos"intrinsece malum".In moral theology, the formulation of an absolute is equivalent to the establishment of an absolutely connecting norm-that is, a norm that obliges all agents in all circumstances, without being conditioned by the intention with which the agent would have engaged in the behavior relevant to the norm. Generally speaking, we treat here of positive norms that do not refer to behavior but, rather, to human nature as such.-for example, the principies of the Mosaic Law, "love your God and your neighbor." But above all, we are before a moral absolute when we hear the cali that Christ makes to follow him, a very unique absolute, since we easily discover that it constitutes an impossible absolute. In other words, we discover that, here, Christ asks for what only He can give and, in fact, gives. Another absolute, of another nature, are the negative absolutes; that is to say, not the acts that must always be performed, but those that can never be performed-the instrinsece malum acts.

  8. Leg Regrowth in Blaberus discoidalis (Discoid Cockroach following Limb Autotomy versus Limb Severance and Relevance to Neurophysiology Experiments.

    Directory of Open Access Journals (Sweden)

    Timothy C Marzullo

    Full Text Available Many insects can regenerate limbs, but less is known about the regrowth process with regard to limb injury type. As part of our neurophysiology education experiments involving the removal of a cockroach leg, 1 the ability of Blaberus discoidalis cockroaches to regenerate a metathoracic leg was examined following autotomy at the femur/trochanter joint versus severance via a transverse coxa-cut, and 2 the neurophysiology of the detached legs with regard to leg removal type was studied by measuring spike firing rate and microstimulation movement thresholds.First appearance of leg regrowth was after 5 weeks in the autotomy group and 12 weeks in the coxa-cut group. Moreover, regenerated legs in the autotomy group were 72% of full size on first appearance, significantly larger (p<0.05 than coxa-cut legs (29% of full size at first appearance. Regenerated legs in both groups grew in size with each subsequent molt; the autotomy-removed legs grew to full size within 18 weeks, whereas coxa-cut legs took longer than 28 weeks to regrow. Removal of the metathoracic leg in both conditions did not have an effect on mortality compared to matched controls with unmolested legs.Autotomy-removed legs had lower spontaneous firing rates, similar marked increased firing rates upon tactile manipulation of tibial barbs, and a 10% higher electrical microstimulation threshold for movement.It is recommended that neurophysiology experiments on cockroach legs remove the limb at autotomy joints instead of coxa cuts, as the leg regenerates significantly faster when autotomized and does not detract from the neurophysiology educational content.

    Majewski osteodysplastic primordial dwarfism type II (MOPDII) is characterized by severe prenatal and postnatal growth failure with microcephaly, characteristic skeletal dysplasia, an increased risk for cerebrovascular disease, and insulin resistance. MOPDII is caused by mutations in the pericentrin (PCNT) gene and is inherited in an autosomal-recessive manner. This study aimed to determine the incidence of hip pathology in patients with molecularly confirmed MOPDII and to describe the functional outcomes of surgical treatment. Thirty-three enrolled patients had a clinical diagnosis of MOPDII. Biallelic PCNT mutations or absent pericentrin protein was confirmed in 25 of these patients. Twelve patients (7 female) had appropriate clinical and radiographic records at this institution and were included in this study. The data collected included age at presentation, age at surgery, sex, body weight and height, weight-bearing status at diagnosis, and the clinical examination. Four patients (31%) had coxa vara: 3 unilateral and 1 bilateral. Three unilateral patients had in situ pinning at a mean age 4 years. The patient with bilateral coxa vara had valgus osteotomy at the age of 5 years. Two children had bilateral hip dysplasia and subluxation with no surgery. One patient had bilateral developmental hip dislocations. The patient was treated by open reduction-spica cast and 2 years after surgery, coxa valga was noted. Another patient was diagnosed at an age of 12 years with bilateral avascular necrosis of the hips. Four patients did not have hip pathology. Hip pathology is common among children with MOPDII; coxa vara is the most frequent diagnosis. Routine clinical and radiographic hip evaluation is important. The capital femoral epiphysis appears to slip down along the shaft, giving the appearance of a proximal femoral epiphysiolysis. A hip diagnosed with slipped capital femoral epiphysis in early life may progress to severe coxa vara. Level IV.

    Subject of this paper is the interpretation of disease as physical evil (malum physicum) by the university professors Philipp Melanchthon (1497-1560) and Caspar Peucer (1525-1602) at Protestant Wittenberg. Melanchthon and Peucer settled the problem of theodicy principally by theological strategies of moralization and compensation. In most cases, therefore, disease resulted from inadequate health behavior, especially drunkenness, furthermore from disdain for medicine and obstruction of divine healing. As a rule, natural factors (e.g. celestial bodies or human affections) only contributed to disease. In general it was caused by free will. In consequence the strategies of depotentiation and functionalization of disease became insignificant resulting in the accentuation of its evil nature. By way of compensation Melanchthon and Peucer stressed the Divine healing of disease. God created the natural remedies and later He created the medical arts by granting heroic virtue to the greatest doctors (Hippocrates, Galen, Avicenna). Moreover the divine Trinity could directly harmonize affections. Thus, God incited a psychosomatical healing within the human organism. As far as physical evil is concerned Lutheran pathology substituted medieval pessimism for therapeutical optimism. Melanchthon and Peucer strived to discipline the patients' behavior and to legitimate the medical arts by God. In this sense their pathology formed part of a program of social and religious stabilization. The academic medicine profited greatly from that program in later years.

    The Banc d'Arguin, a non-estuarine area of shallows and intertidal flats off the tropical Saharan coast of Mauritania, is characterised by extensive intertidal and subtidal seagrass beds. We examined the characteristics of intertidal seagrass ( Zostera noltii) meadows and bare areas in terms of the presence and abundance of molluscs (gastropods and bivalves). To explain observed differences between molluscan assemblages in seagrass and bare patches, some aspects of the feeding habitat (top-5 mm of the sediment) and of food (organic materials) of molluscs were examined. The novelty of this study is that phytopigments were measured and identified to assess source and level of decay (freshness) of organic material in the sediment and to study their importance as an explanatory variable for the distribution of molluscs. Over an area of 36 km 2 of intertidal flats, at 12 sites, paired comparisons were made between seagrass-covered and nearby bare patches. Within seagrass meadows, dry mass of living seagrass was large and amounted to 180 ±10 g AFDM m - 2 (range 75-240). Containing twice the amount of silt per unit dry sediment mass, seagrass sediments were muddier than bare areas; the relative amount of organic material was also larger. The total number of species of bivalves and gastropods amounted to 27, 14 of which were found only in seagrass areas, 4 only in bare and 9 in both types of habitat. Among the three numerically most abundant species, the bivalves Anadara senilis, Dosinia hepatica and Loripes lacteus, the first was numerically most abundant in bare and the other two in seagrass-covered areas. Bare intertidal areas had greater mean total biomass of molluscs (80.5 g AFDM m - 2 ) than seagrass meadows (30.0 g AFDM m - 2 ). In both habitats, the bulk of the biomass was made up by A. senilis. Excluding this species, bare mudflats contained on average only 3.1 g AFDM m - 2 and seagrass meadows 6.9 g AFDM m - 2 . As compared to previous surveys in 1980-1986, the

    From 1969 to 1980 202 children suffering from chronic renal insufficiency underwent treatment in the Children's Hospital of Heidelberg University. In 36 patients kidney transplantations were performed. Two children developed femoral head necroses before transplantation without corticosteroid therapy. Three patients developed femoral head necroses in one or both sides within one to 24 months after kidney transplantation. All children with femoral head necrosis were suffering from congenital renal disease and had a history of servere renal osteodystrophy which was followed by severe coxa vara. Coxa vara and the resulting faulty loading seem to be essential factors for the development of femoral head necrosis in patients with renal insufficiency before and after kidney transplantation.

    High-speed cinematography with computer aided analysis was used to study equine hindlimb kinematics. Eight horses were filmed at the trot or the pace. Filming was done from the side (lateral) and the back (caudal). Parameters measured from the lateral filming included the heights of the tuber coxae and tailhead, protraction and retraction of the hoof and angular changes of the tarsus and stifle. Abduction and adduction of the limb and tarsal height changes were measured from the caudal filming. The maximum and minimum values plus the standard deviations and coefficients of variations are presented in tabular form. Three gait diagrams were constructed to represent stifle angle versus tarsal angle, metatarsophalangeal height versus protraction-retraction (fetlock height diagram) and tuber coxae and tailhead height versus stride (pelvic height diagram). Application of the technique to the group of horses revealed good repeatability of the gait diagrams within a limb and the diagrams appeared to be sensitive indicators of left/right asymmetries.

    Full Text Available 【Abstract】Femoral neck stress fractures (FNSFs are rare, constituting only 5% of all stress fractures in young adults. These fractures are usually seen in athletes, military recruits and patients with underlying metabolic diseases. The treatment of FNSFs is still controversial because of the inherent complications associated with the treatment procedure. We came across 4 cases of bilateral FNSFs in non-athletic individuals who were manual labourers with-out underlying bony disorders. Two patients with FNSFs and coxa vara deformity on both sides were managed by subtrochanteric valgus osteotomy and dynamic hip screw fixation. One of the remaining two patients was treated by cannulated cancellous screw fixation on one side and sub-trochanteric valgus osteotomy on the other side. The fourth patient received subtrochanteric valgus osteotomy on one side and bipolar hemiarthroplasty on the other side after failed cannulated screw fixation. All the fractures healed without any complications. No evidence of avascular ne-crosis or arthritis was noted in our series. Subtrochanteric valgus osteotomy restores normal neck-shaft angle in pa-tients suffering from FNSFs combined with coxa vara deformity. Moreover, it helps to bring the forces acting around the hip to normal biomechanical levels, leading to fracture union and better results. Replacement arthroplasty is recommended to patients who fail to achieve bony union after fixation. Key words: Fractures, stress; Femoral neck fractures; Coxa vara; Osteotomy

    Background Many insects can regenerate limbs, but less is known about the regrowth process with regard to limb injury type. As part of our neurophysiology education experiments involving the removal of a cockroach leg, 1) the ability of Blaberus discoidalis cockroaches to regenerate a metathoracic leg was examined following autotomy at the femur/trochanter joint versus severance via a transverse coxa-cut, and 2) the neurophysiology of the detached legs with regard to leg removal type was studied by measuring spike firing rate and microstimulation movement thresholds. Leg Regrowth Results First appearance of leg regrowth was after 5 weeks in the autotomy group and 12 weeks in the coxa-cut group. Moreover, regenerated legs in the autotomy group were 72% of full size on first appearance, significantly larger (pbarbs, and a 10% higher electrical microstimulation threshold for movement. Summary It is recommended that neurophysiology experiments on cockroach legs remove the limb at autotomy joints instead of coxa cuts, as the leg regenerates significantly faster when autotomized and does not detract from the neurophysiology educational content.

    Sex assignment of human remains is a crucial step in forensic anthropological studies. The aim of this study was to examine elemental differences between male and female bones using X-ray fluorescence (XRF) and determine if elemental profiling could be used for sex discrimination. Cranium, humerus, and os coxae of 60 skeletons (30 male, 30 female) from the Chiang Mai University Skeletal Collection were scanned by XRF and differences in elemental profiles between male and female bones determined using discriminant analysis. In the cranium, three elements (S, Ca, Pb) were significantly higher in males and five elements (Si, Mn, Fe, Zn, Ag) plus light elements (atomic number lower than 12) were higher in females. In humerus and os coxae, nine elements were significantly higher in male and one element was higher in female samples. The accuracy rate for sex estimation was 60, 63, and 61 % for cranium, humerus, and os coxae, respectively, and 67 % when data for all three bones were combined. We conclude that there are sex differences in bone elemental profiles; however, the accuracy of XRF analyses for discriminating between male and female samples was low compared to standard morphometric and molecular methods. XRF could be used on small samples that cannot be sexed by traditional morphological methods, but more work is needed to increase the power of this technique for gender assignment.

    Full Text Available Nuuanu beatricis n. sp., a new melitid amphipod, is described from shallow-water sandy bottoms on the S and SE coasts of Mallorca (Balearic Islands, Mediterranean. It differs from the rest of its congeners in the combination of: (1 non-geniculate antennule, much longer than antenna; (2 distal segment of mandibular palp shorter than second, armed with both D and E setae; (3 second segment of mandibular palp with 2 setae; (4 posteroventral lobe (sensu Lowry and Watson, 2002 absent from posterior margin of coxa 4; (5 reduced spine present on medial surface of coxa 5; (6 posterior margin of basis of pereopod 5 convex; (7 anterodistal lobe of coxa 7 wanting; (8 posterior margin of basis of pereopod 7 sparsely serrated along proximal half only; (9 pleonites 1-2 lacking dorsodistal spines; (10 anterodistal corner of epimeral plate 1 rounded; (11 exopod of uropod 3 longer than protopod; and (12 telson with terminal spine on each lobe. Although the new amphipod could be an alien species introduced from a distant tropical location with alien Caulerpa algae species, it is here regarded as an ancient Mediterranean element owing to its peracarid condition (i.e. reduced potential for dispersal, regressed visual apparatus, and crevicular-interstitial existence. The presumed presence of sternal gills in Nuuanu is rejected after demonstration of the coxal origin of the spiniform structures interpreted elsewhere as sternal gills.

    The authors determined the results after traction or traction and hip spica treatment of the initial fractures through unicameral bone cysts of the proximal femur in 20 children. All of the eight displaced fractures healed, but with coxa vara and avascular necrosis in one, coxa vara in a second, and coxa breva in a third. Spontaneous healing of the cyst occurred in three of the eight children; satisfactory healing was achieved and maintained after intralesional corticosteroid injections in four of the eight children. In the remaining child with a displaced fracture, reactivation of the cyst and exercise-related pain, indicative of an incipient refracture, occurred 3 years after initial presentation. All of the 12 undisplaced fractures healed without deformity or avascular necrosis. Intralesional corticosteroids were used in all of the 12 children because none of them showed spontaneous healing of their cysts. Satisfactory radiographic healing was achieved 1 year after presentation in all of the 12 children. However, one or more refractures resulting from reactivation of the cyst occurred in 6 of the 12 children 2 to 5 years after initial presentation. The results of this study indicate that satisfactory radiographic healing needs to be achieved by the end of the first year and needs to be maintained thereafter to prevent refractures.

  2. The sejugal furrow in camel spiders and acariform mites

    2012-07-01

    Full Text Available Camel spiders (Arachnida: Solifugae are one of the arachnid groups characterised by a prosomal dorsal shield composed of three distinct elements: the pro-, meso- and metapeltidium. These are associated respectively with prosomal appendages one to four, five, and six. What is less well known, although noted in the historical literature, is that the coxae of the 4th and 5th prosomal segments (i.e. walking legs 2 and 3 of camel spiders are also separated ventrally by a distinct membranous region, which is absent between the coxae of the other legs. We suggest that this essentially ventral division of the prosoma specifically between coxae 2 and 3 is homologous with the so-called sejugal furrow (the sejugal interval sensu van der Hammen. This division constitutes a fundamental part of the body plan in acariform mites (Arachnida: Acariformes. If homologous, this sejugal furrow could represent a further potential synapomorphy for (Solifugae + Acariformes; a relationship with increasing morphological and molecular support. Alternatively, outgroup comparison with sea spiders (Pycnogonida and certain early Palaeozoic fossils could imply that the sejugal furrow defines an older tagma, derived from a more basal grade of organisation. In this scenario the (still divided prosoma of acariform mites and camel spiders would be plesiomorphic. This interpretation challenges the textbook arachnid character of a peltidium (or ‘carapace’ covering an undivided prosoma.

    In case of leg infection in diabetics it is difficult to differentiate between a chronic osteopathy, an infection of the soft tissues and an osteomyelitis (OM). We considered of interest to evaluate by a HMPAO-LS prospective study the diagnosis of osteitis in diabetic legs. Twenty seven diabetic (DID type 1 = 11, DNID type 2 = 16) patients (19 M and 8 F, average age 64 years), clinically suspected with a leg osteo-articular infection (malum perforans or cellulitis, uni- or bi-lateral, unique or multiple lesions) were included in the study. For all of them a standard radiographic examination centered on the legs, a (3 phases) osseous scintigraphy and a HMPAO-LS were achieved over 3 days. The HMPAO-LS was considered as in favour of a OM when there was an abnormal accumulation of granulocytes concordant with a hyper-fixation by osseous scintigraphy. In case of 37 retained lesions 20 OM were proved: - 8 sites, on radiological arguments and histological and/or microbiological criteria after osseous biopsy; - 8, by the radiological examination only; - 4, on biopsy arguments, only. Seventeen lesions were not OM, of which 7 were cellulitis. The sensitivity of the HMPAO-LS was 90% with a specificity of 94%. 8/20 OM had initial normal radiographs confirming the precocity of OM diagnosis by HMPAO-LS. Twelve HMPAO-LS were effected in OM evolutive surveillance. All of them became negative on the control initial site of the healing of OM. In conclusion, the HMPAO-LS appears to be an alternative to choose in the diagnosis and in the evolution surveillance of leg OM in diabetics, particularly when the healing of the perforans softs is incomplete and the question of the osteitis healing or sequel of an anti-biotherapy is posed

Avaliações foram feitas quanto a características de: peso de carcaça, peito, coxa e sobrecoxa; altura, largura e comprimento do peito; e comprimento da coxa e da sobrecoxa. Os dados foram submetidos às análises de variáveis canônicas e à análise discriminante independente do tamanho (ADIT. Os resíduos da ADIT foram utilizados na análise de agrupamento pelos métodos de Tocher e UPGMA. As duas primeiras variáveis canônicas foram suficientes para explicar 94,66% da variação total entre os fenótipos. O peso da carcaça teve a maior contribuição para a variação (59,91% entre os grupos de aves, seguido de peso da coxa (12,63% e largura do peito (11,75%. Ambos os métodos de agrupamento resultaram na formação de dois grupos: um de linhagens comerciais e outro da raça Peloco. O isolamento da Peloco é consequência da ausência de seleção para as características estudadas. Além disso, a presença de variabilidade dentro da raça Peloco mostra a existência de animais com maior potencial quanto ao peso de carcaça, o que possibilita o melhoramento da raça.

    To evaluate the role of a modified Pauwels' intertrochanteric osteotomy (MPIO) in neglected femoral neck fractures in children. Prospective study with retrospective analysis. Tertiary care Postgraduate Institute of Medical Sciences. Ten children (8 males, 2 females) with an average age of 10.2 years with neglected femoral neck fractures were seen from 1990 to 1998. A femoral neck fracture was considered neglected when no proper medical treatment was instituted for at least 1 month following the fracture. Nonunion was accompanied by coxa vara and resorption of the femoral neck in 9 patients; a 10th patient had a neglected femoral neck fracture for 1 month without coxa vara. Three patients at time of presentation with Delbet Type II displaced fractures with associated nonunion and coxa vara (2 with Ratliff Type III and 1 with Type I) also had avascular necrosis using plain radiographic criteria of increased density. Modified Pauwels' intertrochanteric osteotomy. The children were immobilized in a hip spica for 6-10 weeks postoperatively and weightbearing was started after hip spica removal. Fracture healing, neck-shaft angle, avascular necrosis, and functional outcome. Patients were followed for an average of 8.2 years (range 5-12 years). All patients had union of their fracture within an average of 16.6 weeks (12-20 weeks) and of the osteotomy site within 8.2 weeks (7-9 weeks). Radiologic signs of avascular necrosis disappeared completely in the 3 patients who presented with avascular necrosis. In 1 patient with a preoperatively viable femoral head, radiologic signs of Ratliff Type I avascular necrosis appeared between 60 and 98 weeks. This radiologic finding became normal again, indicating viability of the femoral head somewhere between 98 to 205 weeks of follow-up. Postoperatively, an average of 135-degree neck-shaft angle was achieved (range 125-160 degrees). The average preoperative neck-shaft angle was 104.4 degrees (range 92-120 degrees) and on the normal hip

    A probable new type of osteopenic bone disease in two sisters and one female cousin is described. In infancy, the radiological findings were osteopenia, coxa vara, periosteal cloaking, bowing of the long bones, and flaring of the metaphyses. During growth, spinal pathology developed with compression of the vertebral bodies and scoliosis in one girl and kyphosis in another. All three children had genu valgum and two developed severe S-shaped bowing of the tibiae. Growth was stunted. Inheritance of this disorder is probably recessive. Type I and III collagen biosynthesis was normal. This condition is probably a hitherto undescribed form of osteogenesis imperfecta type III or a new bone disease. (orig.)

    Analysis of 20 cases of metaphyseal chondrodysplasia, Schmid type as well as a review of the world literature reveals a specific autosomal dominant disorder that was often over diagnosed in the past, sometimes resulting in incorrect genetic counselling. Significant radiologic features include an enlarged capital femoral epiphysis in early childhood, coxa vara, greater involvement of the distal femoral metaphysis than the proximal, anterior rib changes and a normal spine. Chondroosseous morphology is not specific. Presentation in nonfamilial cases is no earlier than the second year of life. (orig.)

    Xenoberotha angustialata gen. et sp. nov. (Neuroptera: Berothidae) is described from the early Eocene of the Parachute Creek Member of the Green River Formation (U.S.A., Colorado). It is assigned to Berothinae as an oldest known member of the subfamily based on the presence of scale-like setae on the foreleg coxae. Distal crossveins of the fourth (outer) gradate series which are located very close to the wing margin in Xenoberotha gen. nov. is a character state previously unknown in Berothinae.

    Full Text Available Cornelia de Lange Syndrome (CdLS (also called Bushy Syndrome or Amsterdam dwarfism, is a genetic disorder that can lead to several alterations. This disease affects both physical and neuropsychiatric development. The various abnormalities include facial dysmorphia (arched eyebrows, synophrys, depressed nasal bridge, long philtrum, down-turned angles of the mouth, upper-extremity malformations, hirsutism, cardiac defects, and gastrointestinal alterations. The prevalence of this syndrome is approximately one per 15,000. Ultrasound is not the perfect means to diagnose CdLS, however, many abnormalities can be detected prenatally by scrupulous image observation. We report an atypical CdLS case characterized by increased nuchal translucency in the first trimester, normal karyotype, saddle nose, micrognathia with receding jaw, low set ears, facies senilis, arthrogryposis of the hands, absence of the Aranzio ductus venous, dilatation of gallbladder and bowel, a unique umbilical artery, increased volume of amniotic fluid, and intrauterine growth retardation ending with the interruption of pregnancy.

    Age spots, also called solar lentigines and lentigo senilis, are light brown to black pigmented lesions of various sizes that typically develop in chronically sun-exposed skin. It is well known that age spots are strongly related to chronic sun exposure and are associated with photodamage and an increased risk for skin cancer, however, the mechanism(s) underlying their development remain poorly understood. We used immunohistochemical analysis and microarray analysis to investigate the processes involved in their formation, focusing on specific markers associated with the functions and proliferation of melanocytes and keratinocytes. A total of 193 genes were differentially expressed in age spots but melanocyte pigment genes were not among them. The increased expression of keratins 5 and 10, markers of basal and suprabasal keratinocytes, respectively, in age spots suggests that the increased proliferation of basal keratinocytes combined with the decreased turnover of suprabasal keratinocytes leads to the exaggerated formation of rete ridges in lesional epidermis which in turn disrupts the normal processing of melanin upwards from the basal layer. Based on our results, we propose a model for the development of age spots that explains the accumulation of melanin and the development of extensive rete ridges in those hyperpigmented lesions.

    Benefits conferred on plants in ant-mediated seed dispersal mutualisms (myrmecochory) depend on the fate of transported seeds. We studied the effects of elaiosome presence, seed size and seed treatment (with and without passage through a bird's digestive tract) on short-term seed fate in Rhamnus alaternus. In our study, we define short-term seed, or initial, seed fate, as the location where ants release the seeds after ant contact with it. The elaiosomes had the most influence on short-term fate, i.e. whether or not seeds were transported to the nest. The workers usually transported big seeds more often than small ones, but small ants did not transport large seeds. Effect of seed size on transport depended on the ant species and on the treatment of the seed (manual extraction simulating a direct fall from the parent plant vs. bird deposition corresponding to preliminary primary dispersal). Probability of removal of elaiosome-bearing seeds to the nest by Aphaenogaster senilis increased with increasing seed weight.

    Using experimental and computational methods, we study the role of behavioural variability in activity bursts (or temporal activity patterns) for individual and collective regulation of foraging in A. senilis ants. First, foraging experiments were carried out under special conditions (low densities of ants and food and absence of external cues or stimuli) where individual-based strategies are most prevalent. By using marked individuals and recording all foraging trajectories, we were then able to precisely quantify behavioural variability among individuals. Our main conclusions are that (i) variability of ant trajectories (turning angles, speed, etc.) is low compared with variability of temporal activity profiles, and (ii) this variability seems to be driven by plasticity of individual behaviour through time, rather than the presence of fixed behavioural stereotypes or specialists within the group. The statistical measures obtained from these experimental foraging patterns are then used to build a general agent-based model (ABM) which includes the most relevant properties of ant foraging under natural conditions, including recruitment through pheromone communication. Using the ABM, we are able to provide computational evidence that the characteristics of individual variability observed in our experiments can provide a functional advantage (in terms of foraging success) to the group; thus, we propose the biological basis underpinning our observations. Altogether, our study reveals the potential utility of experiments under simplified (laboratory) conditions for understanding information-gathering in biological systems. © 2016 The Author(s).

  2. Vitreous in lattice degeneration of retina.

    A localized pocket of missing vitreous invariably overlies lattice degeneration of the retina. Subjects with lattice also have a higher rate of rhegmatogenous retinal detachment, which is usually a complication of retinal tears. The latter are in turn a result of alterations in the central vitreous--that is, synchysis senilis leading to posterior vitreous detachment. In order to determine if there is either an association or a deleterious interaction between the local and central lesions of the vitreous in eyes with lattice, a comparison was made in autopsy eyes with and without lattice the degree of synchysis and rate of vitreous detachment. Results show no association between the local and central vitreous lesions, indicating that a higher rate of vitreous detachment is not the basis for the higher rate of retinal detachment in eyes with lattice. Also, there was no suggestion of deleterious interaction between the local and central vitreous lesions, either through vitreodonesis as a basis for precocious vitreous detachment, or through a greater degree of synchysis as a basis for interconnection of local and central lacunae (which could extend the localized retinal detachment in eyes with holes in lattice degeneration).

    Full Text Available A composição química da carne e o rendimento de carcaça de perdizes (Rhynchotus rufescens adultas, com 12 meses, criadas em cativeiro com rações balanceadas, foram determinadas neste trabalho. Para rendimento de carcaça, após o abate e evisceração, foram feitos dois cortes: peito e coxa+sobrecoxa+dorso. Para análise química, foram retiradas três amostras de cada corte para determinação da composição centesimal da umidade, proteínas totais, lipídeos totais, cinzas e colesterol. Os valores observados mostraram um rendimento médio de carcaça de 74,4% com 36,6% de carne de peito. Os componentes químicos apresentaram para os cortes de coxa-sobrecoxa e peito, respectivamente, umidade 62,4 e 55,9%; proteínas 25,2 e 29,1%; lipídeos 1,6 e 5,6%; cinzas 1,4 e 1,2% e colesterol 234 e 70mg/100g. O excelente rendimento de carcaça, somado à composição química de sua carne, mostra o potencial desta espécie para a produção de carnes especiais.

    Full Text Available O objetivo deste experimento foi avaliar a influência da variação do nível de energia metabolizável na dieta de frangos de corte, associada a uma variação proporcional da densidade nutricional da ração, sobre o desempenho das aves e sobre a composição da fração lipídica da carne. Foram avaliados separadamente machos e fêmeas da linhagem Cobb 500. Para análise de desempenho, foi utilizado um delineamento inteiramente casualizado em esquema fatorial 6x3, sendo seis níveis de energia metabolizável na ração (2.800, 2.900, 3.000, 3.100, 3.200 e 3.300kcal kg-1 e três idades ao abate (42, 49 e 56 dias. Foi utilizada a metodologia de superfície de resposta para estabelecer um modelo matemático, explicando o comportamento do peso vivo, do consumo de ração e da conversão alimentar. Para a avaliação da composição da fração lipídica da carne, determinou-se o teor de lipídeos totais e de colesterol na carne do peito, na coxa com pele e na coxa sem pele, seguindo um delineamento inteiramente casualizado em esquema fatorial 3x3x2, sendo três níveis de energia metabolizável na ração (2.800, 3.000 e 3.300kcal kg-1 de ração, três idades ao abate (42, 49 e 56 dias e dois sexos. A redução da energia metabolizável da ração até valores próximos de 3.000kcal kg-1 não afetou o peso vivo, mas, reduzindo a energia da ração abaixo desse valor, o peso vivo diminui. O consumo de ração foi menor quando o nível energético da ração foi mais alto. A conversão alimentar melhorou de forma proporcional ao aumento do nível energético da ração. O desempenho de todas as aves ficou dentro da faixa considerada adequada para a linhagem. A carne de peito apresentou menos lipídeos totais e colesterol que a carne da coxa. O teor de lipídeos totais da coxa com pele foi mais que o dobro da coxa sem pele, mas o teor de colesterol não diferiu com a retirada da pele, demonstrando que o colesterol não está associado à gordura

    To explore optimal choice of surgical treatment for subtrochanteric fractures in older children. A retrospective study of 36 older children with subtrochanteric fractures was performed between January 2010 and January 2012. Among them, 18 patients (11 males and 7 females) aged from 7 to 13 years old with an average of 9.4 were treated with titanic elastic nail (TEN) fixation, 4 cases were Type II A, 3 cases were II B, 2 cases were II C, 4 cases were III A, 3 cases were III B according to Seinsheimer classification. Eighteen patients (10 males and 8 females) aged was from 8 to 13 years with an average of 9.6 were treated with locking compression pine (LCP) fixation, and 3 cases were Type II A, 4 cases were II B, 3 cases were II C, 4 cases were IIIA, 2 cases were III B. Fracture healing time, postoperative complications (including wound infection, failure and breakage of internal fixtion, deformities of angular on the sagittal view, deformities of coxa vara) and recovery of hip joint function were observed and recorded. All children were followed up from 15 to 36 months with an average of 21. Fracture were all healed, the time ranged from 7 to 16 weeks (mean 9.5). Three cases in TEN group occurred mild deformities of angular on the sagittal view, 3 cases occurred deformities of coxa vara and 2 cases occurred limb shortening; while 1 case occurred mild deformities of angular on the sagittal view, and no deformities of coxa vara and limb shortening occurred in LCP group. No early close of epiphyseal injury, avascular necrosis of femoral head occurred. Clinical efficacy were evaluated by Sanders standard, 14 cases got excellent results, 3 cases were moderate in LCP group, while 9 cases in excellent, 4 in moderate in TEN group. There were no significant differences between two group in recovery of hip joint function and complications. For the treatment of subtrochanteric fractures in older children,the efficacy of LCP fixation is better than that of TFN fixation, which

    Varus or valgus deviations of the femoral neck in osteogenesis imperfecta have been an ignored chapter because the classic correction procedures were applied in medical practice with unsatisfying results. Until the use of telescopic rods, coronal deviations remained unsolved and the distal configuration of the proximal femoral extremity remained uncorrected or partially corrected, which required an extensive use of the wheel chair or bed immobilization of the patient. The concomitant correction of the complex deformities, coxa vara/valga and femoral integrated configuration, have been a progress which allowed the patients to walk with or without support. The purpose of this study is to present the Burnei's technique, a therapeutic alternative in deformity corrections of the varus or valgus hip in children with osteogenesis imperfecta. The paper is about a retrospective study done in a single center, which analyses Burnei technique and other procedures described in literature. The content of the article is based on a 12 years experience on a batch of 51 patients with osteogenesis imperfecta from which 10 patients (13 hips) presented frontal plane deviations of the femoral neck. All the patients with osteogenesis imperfecta who presented coxa vara or valga were submitted to investigations with the purpose of measuring blood loss, the possibility of extending the surgical intervention to the leg, the association of severe deformities of the proximal extremity of the femur and the necessity of postoperative intensive care. Burnei's technique: The operation was first performed in 2002. A subtrochanteric osteotomy was made in an oblique cut, from the internal side to the external side and from proximal to distal for coxa vara, or by using a cuneiform resection associated with muscular disinsertions. Only telescopic rods were used for osteosynthesis. There are a few articles in literature, which approach corrections of vara or valgus deviations in osteogenesis imperfecta

    Ants provide one of the best examples of the division of labor in animal societies. While the queens reproduce, workers generally refrain from laying eggs and dedicate themselves exclusively to domestic tasks. In many species, the small diploid larvae are bipotent and can develop either into workers or queens depending mostly on environmental cues. This generates a conflicting situation between the adults that tend to rear a majority of larvae into workers and the larvae whose individual interest may be to develop into reproductive queens. We tested the social regulation of larval caste fate in the fission-performing ant Aphaenogaster senilis. We first observed interactions between resident workers and queen- and worker-destined larvae in presence/absence of the queen. The results show that workers tend to specifically eliminate queen-destined larvae when the queen is present but not when she is absent or imprisoned in a small cage allowing for volatile pheromone exchanges. In addition, we found that the presence of already developed queen-destined larvae does not inhibit the development of younger still bipotent larvae into queens. Finally, we analyzed the cuticular hydrocarbon profiles of queen- and worker-destined larvae and found no significant quantitative or qualitative difference. Interestingly, the total amount of hydrocarbons on both larval castes is extremely low, which lends credence on the chemical insignificance hypothesis of larval ants. Overall, our results suggest that workers control larval development and police larvae that would develop into queens instead of workers. Such policing behavior is similar in many aspects to what is known of worker policing among adults.

SED congenita and SED tarda are two different clinical forms of this disease. SED tarda with progressive arthropathy is another rare clinical appearance. SED is more frequently seen in male patients due to a genetic recessive transmission by chromosome X. The disease is characterized by a delay in the formation of epipysis, shortness of spine and extremities, kyphoscoliosis, coxa vara and platyspondily. In this case report we aimed to discuss an adolescent male SED tarda patient with early onset of osteoarthritis and osteoporosis, who was diagnosed as Scheuerman disease in the orthopedics clinic and treated with growth hormone for growth retardation in the pediatric endocrinology clinic. Important findings and labotatory investigation methods for diagnosis and treatment of this diasese will be outlined. (From the World of Osteoporosis 2009;15:79-82

    Infestation with Sarcoptes scabiei was diagnosed from four wild raccoon dogs (Nyctereutes procyonoides) accidentally captured and presented to the Animal Health Center in Seoul Grand Park Zoo, Korea. Diagnosis was done by microscopic and histologic examination from skin lesions. Sarcoptes scabiei was the only species detected from the lesions and characterized by dorsoventrally flattened and round bodies, sucker-like pulvilli borne on long nonjointed pretarsi, triangular scales and spinelike setae on the dorsum, and three epimeres that are chitinous extensions of the coxae of the legs. In addition, infiltration of mast cells in the dermis was associated with infestation of the burrowing mite. This is the first report of sarcoptic mange in raccoon dogs in Korea. Because heavy infestation with S. scabiei was found in all of the captured wild raccoon dogs, further work is necessary to develop prophylactic interventions to prevent the spread of sarcoptic mange in free-living raccoon dogs in Korea.

    A male Holstein-Friesian calf with seven legs was examined macroscopically and radiographically. External features included two normal forelimbs, two normal hindlimbs (lateral hindlimbs), and two abnormal hindlimbs (medial hindlimbs) which were underdeveloped. Also, a rudimentary forelimb, which was attached to the pelvic region, was observed between both the medial hindlimbs. It consisted of an underdeveloped humerus, a duplicated ulna, several carpal bones, a partially duplicated metacarpal bone and three digits with three hoofs. This leg was connected with two sets of coxae by a irregular-shaped bone considered the vestigial vertebrae and ribs. Two penises and scrotums, three kidneys and testes were also observed. This calf is the first case of dipygus associated with pygopagus parasiticus in cattle. Based on these findings, the pathogenesis of this rare anomaly was briefly discussed from an embryological point of view

    We report an 18-year-old boy with occipital horn syndrome who developed aneurysms of the splenic and hepatic arteries. Occipital horn syndrome, also called X-linked cutis laxa or Ehlers-Danlos syndrome (EDS) type IX, is characterised by a skeletal dysplasia which includes occipital horns, broad clavicles, deformed radii, ulnae and humeri, narrow rib cage, undercalcified long bones and coxa valga. Distinctive features common to all patients are unusual facial appearance, hypermobility of finger joints, limitation of extension of elbows, chronic diarrhoea and genitourinary abnormalities. In this case report we describe the difficulties encountered in the diagnostic management of patients with EDS-related vascular lesions. (orig.) With 5 figs., 2 tabs., 12 refs.

    Over a period of recent 3 years, the 5 cases of polyostotic fibrous dysplasia were proven histologically at National Medical Center, and they were evaluated and analyzed radiologically and clinically. The results were as follows: 1. The age of 5 patients ranged from 12 to 21. 2. In general, clinical symptoms of these patients were pain of affected sites and swelling , fracture, walking disturbance of lower extremities. 3. The order of frequent site of polyostotic fibrous dysplasia was skull (4 cases), femur (3 cases), maxilla (2 case), humerus, tibia, rib, radius, metacarpal bone and phalanx. 4. The characteristic radiological findings of polyostotic fibrous dysplasia were multicystic lesions with ground glass appearance, osteosclerosis, cortical thinning and pathologic fracture and deformity of long bones. Particularly, in the extremities, multicystic radiolucencies, groud glass appearance, shepherd's crook and coxa vara deformities were noticed, and in the skull and maxilla, sclerotic changes were principally demonstrated.

    Abnormalities of femoral neck version have been associated with a number of hip abnormalities in children, including slipped capital femoral epiphysis, proximal femoral focal deficiency, coxa vara, a deep acetabulum and, rarely, developmental dysplasia of the hip. Orthopedic surgeons also are interested in quantifying the femoral neck anteversion or retroversion in children especially to plan derotational osteotomies. Historically, the angle of femoral version and tibial torsion has been measured with the use of radiography and later by CT. Both methods carry with them the risks associated with ionizing radiation. Techniques that utilize MR are used less often because of the associated lengthy imaging times. This article describes a technique using MRI to determine femoral neck version and tibial torsion with total scan times of approximately 10 min. (orig.)

All patients showed minimum of one malformation. Prevalences of Tönnis grade 0-1 were 22.6% and 2-3 were 77.4%. CONCLUSION: All......INTRODUCTION: In Denmark, 20% of all registered total hip arthroplasties (THA) from 1995 to 2014 has been patients younger than 60 years with primary idiopathic osteoarthritis (OA). It is speculated that hip malformations may be a major contributor to early OA development. It has been shown...... that hip malformation may compromise implant position and, therefore, identifying and knowing the incidence of malformations is important. Our aim was to assess the prevalence and type of hip malformations in a cohort of younger patients undergoing THA. MATERIALS AND METHODS: In this prospective two center...

    Full Text Available A paradigmática narrativa bíblica escolhida por Auerbach – que é contrastada ao episódio homérico da descoberta da cicatriz na coxa de Ulisses, na Odisséia – é, justamente, aquela do sacrifício de Abraão. A trama prototípica pela própria obscuridade deixa vislumbrar os significantes manifestos em estranho conflito com o que não pode ser expresso. A voz de Deus, como demonstra Auerbach, surge de algum lugar obscuro, recebendo mesmo assim a pronta resposta de Abraão que, apesar de tudo, estava preparado para responder imediata e obedientemente ao chamado misterioso e que sequer é deslocado, uma vez que o espaço de sua manifestação não é esboçado na curta narrativa do episódio.

    This article questions the stagnation of breeding results by hip dysplasia screening and its current etiology. The ''Coxa Valga Antetorta'', anteversion of the hip joint and ''soft tissue displasia'' are discussed besides a multitude of primary diseases leading to growth deformities and other diseases in the hip. Ectopic primary causes like malformation of the spine leading to a secondary ''dysplatic'' osteoarthritis of the hip (functional secondary dysplasia) are also discussed in this article. Recent and very promising breeding strategies (estimation of the breeding value) in the battle against hip dysplasia are presented. Biochemical, immunological and structural aspects are presented as a not totally utopic perspecitive. Molecular genetic markers for hip dysplasia will offer in the near future a possibility to detect carriers ct the disease by a blood sample ion before clinical manifestation

  8. Cellular tropism, population dynamics, host range and taxonomic status of an aphid secondary symbiont, SMLS (Sitobion miscanthi L type symbiont.

    Directory of Open Access Journals (Sweden)

    Tong Li

    Full Text Available SMLS (Sitobion miscanthi L type symbiont is a newly reported aphid secondary symbiont. Phylogenetic evidence from molecular markers indicates that SMLS belongs to the Rickettsiaceae and has a sibling relationship with Orientia tsutsugamushi. A comparative analysis of coxA nucleotide sequences further supports recognition of SMLS as a new genus in the Rickettsiaceae. In situ hybridization reveals that SMLS is housed in both sheath cells and secondary bacteriocytes and it is also detected in aphid hemolymph. The population dynamics of SMLS differ from those of Buchnera aphidicola and titer levels of SMLS increase in older aphids. A survey of 13 other aphids reveals that SMLS only occurs in wheat-associated species.

    We report on a Japanese family of four generations with an autosomal dominant precocious osteoarthropathy. The cardinal clinical manifestations of affected individuals were painful weight-bearing large joints, which started in late childhood or adolescence. The radiological hallmarks included coxa plana, mild epiphyseal dysplasia of the knee, and round talar domes with tibiotalar slant in childhood, which evolved into degenerative joint diseases in adulthood. The disease phenotype was cosegregated with a mutation of the cartilage oligomeric matrix protein (COMP) gene in the family members, who underwent molecular evaluation. COMP mutations have been reported in a mild form of multiple epiphyseal dysplasia (MED), Ribbing type, as well as allied disorders with more severe manifestations, such as MED Fairbank type and pseudoachondroplasia. Unlike previously reported cases with the Ribbing type, the present patients did not have short stature or brachydactyly. This report expands further the phenotypic variations of COMP defects.

    2017-10-16

    When faced with commingled remains, it might be assumed that a more "masculine" pelvis is associated with a more "masculine" cranium, but this relationship has not been specifically tested. This study uses geometric morphometric analyses of pelvic and cranial landmarks to assess whether there is an intra-individual relationship between the degrees of sexual expression in these two skeletal regions. Principal component and discriminant function scores were used to assess sexual dimorphism in 113 U.S. Black individuals. Correlation values and partial least squares regression (PLS) were used to evaluate intra-individual relationships. Results indicate that the os coxae is more sexually dimorphic than the cranium, with element shape being more sexually dimorphic than size. PLS and correlation results suggest no significant intra-individual relationship between pelvic and cranial sexual size or shape expression. Thus, in commingled situations, associations between these skeletal elements cannot be inferred based on degree of "masculinity." © 2017 American Academy of Forensic Sciences.

  12. Resilin and chitinous cuticle form a composite structure for energy storage in jumping by froghopper insects

    Directory of Open Access Journals (Sweden)

    Shaw Stephen R

    2008-09-01

    Full Text Available Abstract Background Many insects jump by storing and releasing energy in elastic structures within their bodies. This allows them to release large amounts of energy in a very short time to jump at very high speeds. The fastest of the insect jumpers, the froghopper, uses a catapult-like elastic mechanism to achieve their jumping prowess in which energy, generated by the slow contraction of muscles, is released suddenly to power rapid and synchronous movements of the hind legs. How is this energy stored? Results The hind coxae of the froghopper are linked to the hinges of the ipsilateral hind wings by pleural arches, complex bow-shaped internal skeletal structures. They are built of chitinous cuticle and the rubber-like protein, resilin, which fluoresces bright blue when illuminated with ultra-violet light. The ventral and posterior end of this fluorescent region forms the thoracic part of the pivot with a hind coxa. No other structures in the thorax or hind legs show this blue fluorescence and it is not found in larvae which do not jump. Stimulating one trochanteral depressor muscle in a pattern that simulates its normal action, results in a distortion and forward movement of the posterior part of a pleural arch by 40 μm, but in natural jumping, the movement is at least 100 μm. Conclusion Calculations showed that the resilin itself could only store 1% to 2% of the energy required for jumping. The stiffer cuticular parts of the pleural arches could, however, easily meet all the energy storage needs. The composite structure therefore, combines the stiffness of the chitinous cuticle with the elasticity of resilin. Muscle contractions bend the chitinous cuticle with little deformation and therefore, store the energy needed for jumping, while the resilin rapidly returns its stored energy and thus restores the body to its original shape after a jump and allows repeated jumping.

    A precise understanding of the radiological anatomy and biomechanics as well as reliable reference values of the hip are essential. The primary goal of this study was to provide reference values of the neck-shaft angle (NSA) for adult patients based on the analysis of rotation corrected computed tomography (CT) scans of 800 hips. The secondary aim was to compare these measurements with simulated anteroposterior roentgenograms of the pelvis. Pelvic CT scans of 400 patients (54.3 years, range 18-100 years; 200 female) were reconstructed in the derotated coronal plane of the proximal femur and as CT-based simulated anteroposterior roentgenograms of the pelvis in the anterior pelvic plane. Femora were categorized as coxa vara (<120 ), physiologic (≥120 to <135 ), and coxa valga (≥135 ). Intra- and inter-rater reliability were analyzed. Primary research question: Mean NSA for male adults was 129.6 (range 113.2 -148.2 ; SD 5.9 ) and 131.9 (range 107.1 -151.9 ; SD 6.8 ) for females in derotated coronal reconstructions. Age (p < 0.001 in both views) and sex influenced the NSA significantly (p = 0.002 and p < 0.001); no significant differences were found between sides (p = 0.722 and p = 0.955). Overall, an excellent reliability of repeated measurements of one or two observers was found (ICC 0.891-0.995). Secondary research question: NSA values measured in the simulated anteroposterior roentgenogram and the rotation corrected coronal reconstruction differed significantly (p < 0.001). While anteroposterior pelvis radiographs are susceptible to rotational errors, the coronal reconstruction of the proximal femur in the femoral neck plane allows the correct measurement of the NSA.

    Objective: To research the image change of JAS and improve the knowledge of this case. Method: 12 patients in this group, 11 males and 1 female. The morbidity age is between 9-16 years old and in average is 13 years old. All the cases use the pelvis platform and R F, HLA-B27 check. Four of them has made the CT and MRI level. Result: In this group, the case is extended over the sacroiliac joint. Among them, there are 5 samples that are referred to both of the coxa articution. The X-rays shows that under the sacroiliac joint, there has 2/3 sclerotin sclerotized and the side of sacroiliac shows this phenomenon especially. The sacroiliac joint is fuzziness and the size of articulation clearance is different, it shows as the sawtooth. When it refers to the coxa articulation, it shows as the acetabular and at the same time the articulation become abnormally. When it refers to the lumber, it shows as that the lumber articulation fuzziness while the articulation clearance disappear. CT level: when affected with this sickness it show that the size of the clearance is different. MRI level: T 1 WI shows that when affected with this case, it express that the size of the clearance is different and at the side of sacroiliac joint can see the low signal which can change into high signal when put it under the T 2 Wi, HLA-B27 is masculine. Conclusion: Because JAS is lack of the adjust ankylosing spondylitis special clinical in the early stage, so it is always be misdiagnosed as the Juvenile rheumatoid arthritis. In fact they are two different cases and treatment is also different. The authors should improve our knowledge about this case. In our opinion, checking of the image and HLA-B27 can diagnose this sickness earlier and correctly. (authors)

    We retrospectively evaluated the pretreatment radiological presentation and the clinicoradiological outcome at the completion of 1 year chemotherapy in osteoarticular tuberculosis of hip in children to prognosticate correlation between them. We retrospectively analyzed the clinical and plain radiographic findings in 27 patients with an age of 12 years or younger in whom hip tuberculosis was diagnosed and treated between 2006 and 2010. The diagnosis was based on histopathology in 14 and clinicoradiological basis in 13 patients. The pre and post treatment plain radiographs were evaluated according to Shanmugasundaram radiological classification and our observations regarding unclassified cases which were not fit in this classification were suggested. The functional outcome at the completion of chemotherapy was assessed using modified Moon's criteria. The male female ratio was 11:16. The left hip was involved more frequently than the right (17:10). The average age was 7.37 years (range, 2-12 years). In the pretreatment radiographs, 9 hips were normal, 6 traveling, 4 dislocating, 1 protrusio acetabuli, 3 atrophic and 4 unclassified types (3 triradiate; 1 pseudarthrosis coxae). There were no Perthes and mortar pestle at the initial presentation. Posttreatment, the types changed to 9 normal, 3 Perthes, 1 protrusio acetabuli, 1 atrophic, 4 mortar pestle and 9 unclassified types (3 triradiate, 3 pseudarthrosis coxae and 3 ankylosed). There were 37% excellent, 18.5% good, 26% fair and 18.5% poor results. The prognosis was best with initial "triradiate" and normal types and worst with posttreatment atrophic and "ankylosed" types. The Shanmugasundaram radiological types accurately predict prognosis only in normal types and "triradiate" pattern. The functional outcome is independent of radiological morphology of the hip in smaller children.

    Full Text Available Introduction. Femoral neck fractures in children and adolescents are rare. However, their complications are frequent - avascular necrosis, femoral neck pseudoarthrosis, premature physeal closure with consequent growth disturbance and coxa vara deformity. Case Outline. A 9.5­year­old boy was injured in a car accident, and femoral neck fracture was diagnosed. Prior to admission at our hospital he was surgically treated several times. He was admitted at our hospital eight months following the accident. On the X­ray transcervical pseudoarthrosis of the femoral neck was found, as well as coxa vara deformity and metaphyseal avascular necrosis. He was operated at our hospital; all previously placed ostefixation material was removed, valgus osteotomy of 30 degrees was done as well as additional local osteoplasty using the commercial osteoindactive agent (Osteovit®. Postoperatively, we applied skin traction, bed rest and physical therapy. At the final follow­up, the patient was recovered completely. He is now painless, the legs are of equal length, range of movements in the left hip is full, life activity is normal. The X­ray shows that the femoral neck pseudoarthrosis is fully healed. Conclusion. This case is presented in order to encourage other colleagues to challenge the problematic situation such as this one. Also, we would like to remind them what one should think about and what should be taken into consideration in the primary treatment of femoral neck fractures in children. Valgus femoral osteotomy, as a part of the primary treatment of femoral neck fracture in children (identically as in the adults can prevent the occurrence of femoral neck pseudoarthrosis.

    Full Text Available Atualmente, a drenagem linfática manual (DLM é um dos recursos de grande destaque no tratamento de edemas, linfedemas e condições inestéticas, porém, na prática clínica têm-se observado sua aplicação de forma iatrogênica. Os objetivos deste relato de caso foram apontar as sequelas da aplicação iatrogênica da DLM, em uma jovem caucasiana, e verificar os efeitos da intervenção fisioterapêutica no tratamento dessas. Voluntária de 27 anos, apresentava-se com uma equimose importante na região lateral da coxa esquerda (28 x 9,5 cm, telangiectasias, microvaricosidades e petéquias em ambas as coxas e pernas, dor de forte intensidade e edema, após ter se submetido a um procedimento manual iatrogênico com finalidade estética há dois dias. As condutas fisioterapêuticas adotadas foram: Ultrassom 3 MHz, pulsado (2 ms on, 8 ms off, 0,4 W/cm² SATP na região da equimose e DLM (Método Leduc durante 20 minutos, na coxa esquerda. Foram realizadas nove sessões até a alta no 16º dia pós-lesão, observando-se apenas a redução gradativa da dor e da equimose. Verificou-se a efetividade da intervenção fisioterapêutica em apenas algumas das sequelas provocadas pela iatrogenia, sem desconsiderar que a remissão espontânea dos sinais e sintomas também pode ter contribuído para tal. Destaca-se a importância de conscientizar os fisioterapeutas que atuam com este procedimento para que o aplique de forma adequada, evitando tais iatrogenias.Recently, the manual lymphatic drainage (MLD is an important resource in the treatment of edemas, lymphedemas, and other unaesthetic conditions.

    Full Text Available Este estudo teve como objetivo descrever a origem e a distribuição do nervo isquiático no veado-catingueiro (Mazama gouazoubira. Dois animais da espécie, obtidos post mortem por atropelamento em rodovia, foram utilizados para o estudo, obedecendo aos critérios da Lei Vigente (Lei 1.153/95. Através da dissecação, a pele foi completamente removida e os animais foram fixados em solução aquosa de formaldeído a 10%. Através de um acesso dorso-lateral, os músculos glúteo superficial, bíceps femoral e glúteo médio foram seccionados no seu local de inserção e rebatidos. Desta forma foi possível visualizar a origem e a distribuição do nervo isquiático, em ambos os antímeros dos animais. As imagens foram registradas com câmera fotográfica digital (Câmera Sony a200, 10.2mpx e os resultados foram descritos com base na Nomina Anatômica Veterinária. Os dados da origem do nervo isquiático nos dois espécimes estudados mostraram que esta ocorre a partir dos ramos ventrais de L6 e S1, podendo ter contribuição de S2. Após a sua emergência pelo forame isquiático maior, em ambos os antímeros, o nervo isquiático fornece ramos para suprir os músculos glúteo médio, glúteo profundo, glúteo superficial, gluteobíceps, bíceps da coxa, semimembranoso, semitendinoso e gastrocnêmio. Próximo ao meio da coxa o nervo isquiático divide-se em nervo tibial e nervo fibular comum os quais inervam os músculos da região distal do membro pélvico. Além disso, o nervo cutâneo caudal da sura pode se originar dos nervos fibular comum ou do nervo tibial. Em conclusão, nos espécimes de Mazama gouazoubira estudados, o nervo isquiático teve sua origem a partir dos ramos ventrais espinais de L6 e S1, podendo ou não ter a contribuição de S2. Na sua distribuição originam-se o nervo glúteo caudal, o nervo cutâneo femoral caudal e ramos musculares, que, conjuntamente inervam os músculos glúteo médio, glúteo profundo, gl

    Full Text Available Para atender às necessidades do mercado consumidor e, assim, agregar valor ao seu produto, a indústria avícola tem procurado formas de se ajustar a esse padrão. Sendo o urucum um excelente pigmentante, este trabalho teve como objetivo avaliar o comportamento do corante na carne de frango cozida. Cem animais foram divididos em quatro grupos e tratados com 0; 1; 2; e 3% de urucum incluso na ração. Para avaliação da coloração dos cortes, foi utilizado o sistema Hunter Lab. Para o parâmetro L, os cortes de peito foram inversamente proporcionais aos cortes de coxa, diminuindo, conforme aumento da porcentagem de urucum para peito, e aumentando, para coxa. Para o parâmetro Croma, os cortes apresentaram comportamento semelhante, aumentando, conforme aumentou a porcentagem de urucum. Os demais parâmetros (a, b e Hue-Angle não tiveram diferenças significativas. Portanto, a utilização de urucum, com a intenção de aumentar a pigmentação da carne frangos, aumenta conforme aumenta a porcentagem de urucum na ração dos animais.The poultry industry has been making an effort to satisfy the needs of the consumers and to add value to their products. Since Annatto is considered an excellent color additive, the aim of this study is to evaluate its behavior in the cooked broiler meat. A hundred animals were divided into four groups and treated with 0; 1; 2, and 3% of annatto in the feed. For the evaluation of the coloration of the cuts, the Hunter Lab system was used. For the parameter L, the breast cuts were inversely proportional to legs cuts, decreasing with the increase of the annatto percentage for the breast cuts and increasing for the leg cuts. For the parameter Chroma, the cuts presented similar behavior, increasing with the increase of the annatto percentage. The other parameters (a, b, and Hue-Angle did not present significant differences. Therefore, the use of annatto to increase pigmentation in broiler meats increases with the

Doados ao Museu de Anatomia Humana e Comparada da UFG (Universidade Federal de Goiás, Campus de Jataí, Proc.CAJ-287/2008. As dissecações e documentação fotográfiica permitiram observar a distribuição do nervo isquiático. O nervo isquiático de mão-pelada inerva o membro pélvico passando entre os músculos glúteo médio e profundo, emitindo ramos para a musculatura da região glútea e da coxa, respectivamente, para os músculos glúteo médio, glúteo bíceps, semimembranáceo, semitendíneo, bíceps femoral, gêmeos, quadrado femoral e adutor magno, emitindo nervo cutâneo lateral e caudal da sura para suprir a pele na superfiície lateral e caudal da perna, respectivamente. Próximo ao meio da coxa bifurca-se em nervo tibial e nervo fiibular comum. O conhecimento anatômico da origem e distribuição do nervo is quiático em mão pelada quando comparado com animais domésticos, silvestres e de fazenda, mostram um padrão de inervação semelhante entre os espécimes.

    Full Text Available A desnervação capsular (DC se baseia na desperiostização da borda acetabular e tem sido utilizada como uma das técnicas de alívio da dor articular em cães displásicos. Compararam-se as técnicas de DC percutânea e aberta, aplicadas em 25 cães, que apresentaram diagnóstico clínico e radiográfico de displasia coxofemoral, totalizando 31 cirurgias. Os efeitos das técnicas foram comparados, em período de 180 dias, por meio de avaliação subjetiva de claudicação e dor, perimetria da coxa, graus máximos de flexão e extensão da articulação coxofemoral e amplitude de movimento articular. Os graus de claudicação e dor apresentaram decréscimo significativo ao longo do período avaliado em ambos os grupos, sem apresentarem diferenças quando comparados entre si. Com relação à perimetria da coxa, flexão, extensão e amplitude de movimento articular, foi observado o aumento dos valores numéricos destas variáveis ao longo do estudo. Baseado nos achados, concluiu-se que a abordagem percutânea ou aberta na DC produz similitude nas variáveis avaliadas, e ambas trazem bons resultados.Joint capsule denervation is based on removal of sensitive fibers from the acetabular edge and has been used as one of the techniques to joint pain relief in the canine dysplastic hip. This study compared the techniques of percutaneous and open hip denervation in 25 dogs that showed clinical and radiographic signs of hip dysplasia, totaling 31 surgeries. The effects of the techniques were evaluated and compared in a period of 180 days following surgery, including subjective evaluation of lameness and pain, thigh girth, maximum degree of hip flexion and extension and range of motion (ROM. Degree of lameness and pain significantly decreased during the study period for both groups, and no difference could be observed between groups.

    Full Text Available INTRODUÇÃO: Crioterapia é qualquer forma de aplicação terapêutica de frio que leva à diminuição da temperatura dos tecidos. OBJETIVO: Comparar as variações na temperatura superficial do músculo quadríceps femoral, em três momentos distintos, quando expostos a duas modalidades de crioterapia: sacos com gelo ou sacos contendo mistura de gelo e água. MATERIAIS E MÉTODOS: Participaram do estudo 18 indivíduos, com idade entre 18 e 25 anos, de ambos os sexos. Em cada voluntário foi realizada, simultaneamente, crioterapia com gelo na coxa esquerda e mistura de gelo e água na coxa direita, durante 15 minutos na região do quadríceps femoral. A temperatura superficial foi mensurada por um termógrafo e foram feitos registros nos seguintes momentos: pré-crioterapia, imediatamente e 15 e 30 minutos após a retirada da modalidade de crioterapia. RESULTADOS: Ambas as modalidades de crioterapia foram eficientes para diminuir a temperatura do quadríceps femoral e a mistura de gelo e água foi capaz de induzir a uma temperatura mais baixa em relação àquela modalidade que usou somente gelo. O resfriamento, para ambas as modalidades, perdurou por, pelo menos, 15 minutos após a retirada do gelo e a temperatura superficial já estava restaurada ao nível pré-aplicação aos 30 minutos após a retirada. CONCLUSÃO: Ambas as modalidades promoveram redução da temperatura que perdurou, pelo menos, durante 15 minutos; e após 30 minutos da retirada das modalidades a temperatura foi restabelecida aos níveis normais. Contudo, a mistura de gelo e água produziu resfriamento maior do que a modalidade de gelo sozinho.

    Full Text Available O objetivo do estudo foi avaliar a variabilidade intra e inter-avaliadores de medidas antropométricas realizadas por três antropometristas considerados experientes mediante o cálculo dos erros técnicos de medida (ETM. Para esse fim, foi selecionada uma amostra de 21 voluntários (25,7 ± 7,5 anos, sendo 12 homens e 9 mulheres. Foram consideradas as medidas de peso corporal (kg, estatura (cm, circunferências (cm do braço direito relaxado, abdômen, quadril e coxa, e da espessura das dobras cutâneas (mm tricipital, subescapular, suprailíaca, abdômen, coxa e panturrilha medial. As medidas foram realizadas em 2 dias consecutivos, sempre no período da tarde, envolvendo os mesmos equipamentos e os mesmos voluntários. Os resultados apontaram a ocorrência de ETMs acima dos recomendados para aceitabilidade, tanto a variabilidade intra-avaliador como inter-avaliadores, sugerindo, portanto, a importância e a necessidade de treinamento específico dos antropometristas.The aim of this study was to evaluate the intra and inter-observer reliability in the anthropometric measures of three expert observers through the technical error of measure (TEM. For this end, 21 healthy volunteers (25.7 ± 7.5 years took part in the study, being 12 males and 9 females. The following aspects were analyzed: body weigh (kg, stature (cm, circumferences (cm of relaxed right arm, abdomen, hip and thigh, and skinfold thickness (mm of triceps, subescapular, supra-iliac, abdomen, thigh and calf medial. The measures were made in 2 different days, always in the afternoon, with the same equipments and in the same volunteers. The results pointed the occurrence of TEMs out of the recommended patterns, in both intra-observer and inter-observers variability. This fact showed the importance and need of specific training of the observers.

    In a recent study on ixodid bat ticks from Eurasia, a high genetic difference was found between Ixodes vespertilionis from Europe and Vietnam. Accordingly, it was proposed that I. vespertilionis is a species complex, with at least one additional, hitherto undescribed species. The aim of the present study was to investigate the morphology of bat ticks from Vietnam and to assess their taxonomic status in comparison with those collected in Europe. Ixodid bat ticks (two females and two nymphs) collected from the pomona leaf-nosed bat (Hipposideros pomona) (Hipposideridae) and intermediate horseshoe bat (Rhinolophus affinis) (Rhinolophidae) in Vietnam showed major morphological differences from European isolates of I. vespertilionis, including the shape of the scutum, the enclosure and shape of porose areas, the presence of a caudo-lateral collar-like ridge ventrally on the basis capituli, polytrich coxae with short setae, and grouped (non-linear) arrangement of anterior pit sensillae in Haller's organ. In this study the female and the nymph of an ixodid bat tick species from Vietnam are described for the first time. The genetic and morphological differences between I. vespertilionis Koch, 1844 and these bat ticks from Vietnam justify the status of the latter as a distinct species, Ixodes collaris Hornok n. sp.

    Full Text Available By using three-dimensional video analysis, we made a kinematic analysis on Grigor Dimitrov’s Serve technique, aiming at finding the kinematic characteristics of his serve technique during various stages. The results showed that: (1 During the stage of tossing the ball and lifting the racket, the tossing height of the ball was at minimum appropriately, while the elbow extension of the tossing arm was stright, and the angle of his left knee was 95.4°, which is beneficial to making greater kicking power; (2 At the back-swing stage, Dimitrov’s both feet made a great range of pedal and stretch quickly, and the “scratch-back” posture is obvious, and momentum caused by the kicking and coxae-turning was rather large; (3 When hitting the ball, the contact point was accurate and the speed of the racket head was high, which passed a relatively large initial momentum to the ball; (4 Dimitrov’s entire service action was integral and coordinate, smooth and powerful, which was in accordance relatedly with kinematic characteristics

    A new commensal ostracod Asterositus ohtsukai n. g., n. sp. (Podocopida: Cytheroidea: Paradoxostomatidae) is described. This new taxon occurs on the ambulacral grooves and wreath of pedicellariae around superomarginal spines of the sea star Sclerasterias euplecta (Fisher) (Asteroidea: Forcipulatida: Asteriidae). Although the family Paradoxostomatidae Brady & Norman, 1889 contains four ectoparasitic or commensal genera, the association with asteroideans has never hitherto been reported. Morphological observations suggested that A. ohtsukai n. g., n. sp. is closely associated with the host sea star as it typically has distal hooks on the antenna and fifth to seventh limbs, and specialised mandibula and maxillula structures that are considered adaptations to a commensal life-style. In addition, this study discussed the feeding habits of A. ohtsukai n. g., n. sp. based on comparison with previous works. The extremely reduced palp and endites of maxillula of A. ohtsukai n. g., n. sp. imply that they have unique feeding habits that are not based on the feeding function of maxillula. From morphological comparisons with siphonostomatoid copepods, we suggest that A. ohtsukai n. g., n. sp. may feed on the body of host sea star by injuring them with styliform needle-like mandibular coxa and sucking the tissues, body fluid, or mucus with the suctorial disc on the oral cone.

    Microcephalic osteodysplastic primordial dwarfism is a syndrome characterized by the presence of intrauterine growth restriction, post-natal growth deficiency and microcephaly. Microcephalic osteodysplastic primordial dwarfism type II is the most distinctive syndrome in this group of entities. Individuals affected by this disease present at an adult height of less than 100 cm, a post-pubertal head circumference of 40 cm or less, mild mental retardation, an outgoing personality and bone dysplasia. We report the first case of a five-year-old Colombian boy of mixed race ancestry (mestizo), with clinical features of microcephaly, prominent and narrow nose, arched palate, amelogenesis imperfecta, short stature, tall and narrow pelvis, disproportionate shortening of fore-arms and legs, and mild coxa vara. Analysis of the PCNT gene by sequencing showed the presence of a nucleotide change in exon 10, c. 1468C>T, evidencing a new mutation not reported in the literature for microcephalic osteodysplastic primordial dwarfism. The new mutation identified in this case could be associated with the severity of the phenotypic expression of the disease, resulting in the extreme short stature of the patient. Further studies are required to reach an explanation that can justify such findings, and it is vital to emphasize the importance of detection and follow-up by the epidemiological surveillance groups in birth defects and rare diseases.

    Full Text Available Data on age and body weight at breeding, parity, previous litter size, days open and some descriptive body linear traits from 389 meat-type, prolific Black Bengal goats in Tripura State of India, were collected for 3 and 1/2 years (2007 to 2010 and analyzed using logistic regression model. The objectives of the study were i to evaluate the effect of age and body weight at breeding, parity, previous litter size and days open on litter size of does; and ii to investigate if body linear type traits influenced litter size in meat-type, prolific goats. The incidence of 68.39% multiple births with a prolificacy rate of 175.07% was recorded. Higher age (>2.69 year, higher parity order (>2.31, more body weight at breeding (>20.5 kg and larger previous litter size (>1.65 showed an increase likelihood of multiple litter size when compared to single litter size. There was a strong, positive relationship between litter size and various body linear type traits like neck length (>22.78 cm, body length (>54.86 cm, withers height (>48.85 cm, croup height (>50.67 cm, distance between tuber coxae bones (>11.38 cm and distance between tuber ischii bones (>4.56 cm for discriminating the goats bearing multiple fetuses from those bearing a single fetus.

    Full Text Available The genus Platymessa Mello-Leitão, 1941 is represented by two species in the Andes of Colombia: P. h-inscriptum Mello-Leitão, 1941 and P. ectroxantha Mello-Leitão, 1941. Platymessa victoriae Pinzón-M. & Townsend, sp. n. is described on the basis of somatic morphological characters and the structure of the penis. The placement of this new species in the genus Platymessa is based upon multiple characters including the outline of dorsal scutum, the presence of a blunt spine on coxa IV, having short and strong legs with femora III and IV having five longitudinal rows of small tubercles, the shape of the basitarsomeres of male leg I, the distribution and relative sizes of the marginal setae on the ventral plate of the penis, and the morphology of the chelicerae and cheliceral sockets. In contrast to other members of the genus, P. victoriae has a pair of triangular tubercles on scutal area III, lacks paired paramedian tubercles on scutal area V, and does not have a ladder mask color pattern on the dorsal scutum. The description of this species expands the distribution of the genus to north of the Oriental Cordillera in the Cesar Department of Colombia.

    Dirofilaria ursi is a filarial nematode of American black bears (Ursus americanus Pallas, 1780) that is vectored by black flies (Simuliidae) in many parts of the United States. In northwestern Wisconsin, the prevalence of microfilaremic bears during the fall hunting season was 21% (n = 47). Unsheathed blood microfilariae from Wisconsin bears possess characters consistent with the original description of D. ursi, as do adult worms observed histologically and grossly. Immunohistochemistry was used to identify the Wolbachia endosymbiont in the hypodermis and lateral cords of an adult female D. ursi. Amplification of wsp, gatB, coxA, fbpA, and ftsZ bacterial sequences from parasite DNA confirmed the presence of Wolbachia, and molecular phylogenetic analysis of the Wolbachia ftsZ gene groups the endosymbiont with Wolbachia from D. immitis and D. repens. Phylogenetic analysis of D. ursi 5s rDNA sequence confirms the morphological observations grouping this parasite as a member of Dirofilaria, and within the Dirofilaria - Onchocerca clade of filarial nematodes. This is the first report of Wolbachia characterization and molecular phylogeny information for D. ursi.

    Osteogenesis imperfecta is a heritable group of collagen-related disorders that affects up to 50,000 people in the United States. Although the disease is most symptomatic in childhood, adults with osteogenesis imperfecta also are affected by the sequelae of the disease. Orthopaedic manifestations include posttraumatic and accelerated degenerative joint disease, kyphoscoliosis, and spondylolisthesis. Other manifestations of abnormal collagen include brittle dentition, hearing loss, cardiac valve abnormalities, and basilar invagination. In general, nonsurgical treatment is preferred for management of acute fractures. High rates of malunion, nonunion, and subsequent deformity have been reported with both closed and open treatment. When surgery is necessary, surgeons should opt for load-sharing intramedullary devices that span the entire length of the bone; locking plates and excessively rigid fixation generally should be avoided. Arthroplasty may be considered for active patients, but the procedure frequently is associated with complications in this patient population. Underlying deformities, such as malunion, bowing, rotational malalignment, coxa vara, and acetabular protrusio, pose specific surgical challenges and underscore the importance of preoperative planning.

  5. Walking on inclines: how do desert ants monitor slope and step length

    Full Text Available Abstract Background During long-distance foraging in almost featureless habitats desert ants of the genus Cataglyphis employ path-integrating mechanisms (vector navigation. This navigational strategy requires an egocentric monitoring of the foraging path by incrementally integrating direction, distance, and inclination of the path. Monitoring the latter two parameters involves idiothetic cues and hence is tightly coupled to the ant's locomotor behavior. Results In a kinematic study of desert ant locomotion performed on differently inclined surfaces we aimed at pinpointing the relevant mechanisms of estimating step length and inclination. In a behavioral experiment with ants foraging on slippery surfaces we broke the otherwise tightly coupled relationship between stepping frequency and step length and examined the animals' ability to monitor distances covered even under those adverse conditions. We show that the ants' locomotor system is not influenced by inclined paths. After removing the effect of speed, slope had only marginal influence on kinematic parameters. Conclusion From the obtained data we infer that the previously proposed monitoring of angles of the thorax-coxa joint is not involved in inclinometry. Due to the tiny variations in cycle period, we also argue that an efference copy of the central pattern generator coding the step length in its output frequency will most likely not suffice for estimating step length and complementing the pedometer. Finally we propose that sensing forces acting on the ant's legs could provide the desired neuronal correlate employed in monitoring inclination and step length.

  6. Friction-Induced Mitochondrial Dysregulation Contributes to Joint Deterioration in Prg4 Knockout Mice

    Full Text Available Deficiency of PRG4 (lubricin, the boundary lubricant in mammalian joints, contributes to increased joint friction accompanied by superficial and upper intermediate zone chondrocyte caspase-3 activation, as shown in lubricin-null (Prg4−/− mice. Caspase-3 activity appears to be reversible upon the restitution of Prg4 either endogenously in vivo, in a gene trap mouse, or as an applied lubricant in vitro. In this study we show that intra-articular injection of human PRG4 in vivo in Prg4−/− mice prevented caspase-3 activation in superficial zone chondrocytes and was associated with a modest decrease in whole joint friction measured ex vivo using a joint pendulum method. Non-lubricated Prg4−/− mouse cartilage shows caspase cascade activation caused by mitochondrial dysregulation, and significantly higher levels of peroxynitrite (ONOO− and −OH and superoxide (O−2 compared to Prg4+/+ and Prg4+/− cartilage. Enzymatic activity levels of caspase 8 across Prg4 mutant mice were not significantly different, indicating no extrinsic apoptosis pathway activation. Western blots showed caspase-3 and 9 activation in Prg4−/− tissue extracts, and the appearance of nitrosylated Cys163 in the active cleft of caspase-3 which inhibits its enzymatic activity. These findings are relevant to patients at risk for arthrosis, from camptodactyl-arthropathy-coxa vara-pericarditis (CACP syndrome and transient lubricin insufficiency due to trauma and inflammation.

    Specific patterns of developmental adaptation of the proximal femur have been recognized in some sports. Gymnastics are characterized by repetitive axial loading and hip rotations in combination with extreme hip positions. It is unknown how and if these forces can affect an immature skeleton in the long term. We sought to evaluate this, by means of magnetic resonance imaging of the hip and groin of such elite asymptomatic athletes. We performed a case-control comparative MR imaging study of both hips and groin of 12 (7 male, 5 female) skeletally mature young (mean age 18.6 years) asymptomatic international level gymnasts with a minimum of 10 years' training with age-matched non-athletes. At the time of recruitment, none of the athletes had a recorded musculoskeletal complaint or injury in the anatomical area around the hip. The study showed that elite gymnasts share four common morphological characteristics on MRI that deviate from normal and are considered to be the result of adaptational changes to the specific sport: high centre-column-diaphysis angle (coxa valga140 on average), ligamentum teres hypertrophy, friction of the iliotibial band with oedema surrounding the greater trochanter, and a high incidence (62.5 %) of radiological appearances of ischiofemoral impingement. Our study showed that elite gymnasts share four common morphological characteristics on MRI that deviate from normal. These findings were in asymptomatic subjects; hence, radiologists and sports physicians should be aware of them in order to avoid unnecessary treatment. (orig.)

    Several therapeutic strategies have been used for managing unicameral bone cyst (UBC) of the proximal femur. However, there is insufficient evidence to support one treatment over another, and the optimal treatment is controversial. This study aims at describing our experience with surgical reconstruction of paediatric UBCs of the proximal femur using a proximal locking plate and fibular strut allograft. In total, 14 consecutive paediatric patients with Dormans types IB (four cases) and IIB (10 cases) UBC were assessed. Mean patient age was 8.6 ± 2.3 years, and mean follow-up period was 41.7 ± 29.8 months. Six patients (42.8%) were referred with a pathologic fracture. Clinical/radiological outcome and complication rates were evaluated at the final follow-up session. No cysts were Capanna's class III (recurrence) or IV (no response). Complete healing (Capanna's class I) was seen in ten cysts, while four other cysts healed with residual radiolucent areas (Capanna's class II). Mean healing period was 14.1 ± 5.1 (9-24 months). One patient had superficial infection, one heterotopic ossification, and one mild coxa vara, and mean Musculoskeletal Tumor Society (MSTS) score was 99.5%. According to our results, locking plate and fibular strut graft in Dormans classification types IB and IIB results in a favorable outcome in managing UBC of the proximal femur in the paediatric population.

  9. Paleopathological description and diagnosis of metastatic carcinoma in an Early Bronze Age (4588+34 Cal. BP forager from the Cis-Baikal region of Eastern Siberia.

    Angela R Lieverse

    Full Text Available Extensive osteolytic and osteoblastic lesions were observed on the skeletal remains of an adult male excavated from an Early Bronze Age cemetery dated to 4556+32 years BP, located in the Cis-Baikal region of Siberia (Russian Federation. Lytic lesions ranged in size from several mm to over 60 mm in diameter and had irregular, moth-eaten borders. Many of these lesions destroyed trabecular bone, though a hollowed shell of cortical bone often remained observable. Radiographic analysis revealed numerous lytic lesions within trabecular bone that had not yet affected the cortex. Blastic lesions were identified as spiculated lines, bands, or nodules of mostly immature (woven bone formed at irregular intervals. Anatomical elements with the greatest involvement included those of the axial skeleton (skull, vertebrae, sacrum, ribs, and sternum as well as proximal appendicular elements (ossa coxae, proximal femora, clavicles, scapulae, and proximal humeri. Osteocoalescence of destructive foci was observed on the ilium and frontal bone, with the largest lesion found on the right ilium. Differential diagnoses include metastatic carcinoma, mycotic infections, tuberculosis, Langerhan's cell histiocytosis, and multiple myeloma. Based on lesion appearance and distribution, age and sex of the individual, as well as pathogen endemism, the most likely diagnostic option for this set of lesions is metastatic carcinoma. The age and sex of this individual and appearance of the lesions may reflect carcinoma of the lung or, possibly, prostate. This represents one of the earliest cases of metastatic carcinoma worldwide and the oldest case documented thus far from Northeast Asia.

    To assess agreement between ultrasonography (transcutaneous and transrectal) and standing radiography in horses with fractures in the pelvic region and disorders of the coxofemoral joint. Case series. Warmblood horses (n=23) and 2 ponies. Medical records (1999-2008) of equids with pelvic or coxofemoral disorders that had pelvic radiography and ultrasonography were retrieved and results of both techniques compared. Radiography and ultrasonography each identified equal numbers of fractures of the tuber coxa (n=4), ilial shaft (2), ischium (3), femoral neck (2), and osteoarthritis/osis of the coxofemoral joint (6). Fractures of the ilial wing (4) were only identified by ultrasonography not by standing radiography. Of 9 acetabular fractures, 3 were identified on radiographs only, 5 were identified with both modalities. One pubic fracture was identified using ultrasonography and radiography. One acetabular and 1 pubic fracture were only diagnosed on necropsy. We found reasonable agreement (73%; 24/33) between ultrasonography and standing radiography for diagnosis of pelvic-femoral disorders. Ultrasonography was more useful for ilial wing fractures and radiography for acetabular fractures. Ultrasonography is a rapid, safe imaging technique for detecting disorders of the pelvic region with a high diagnostic yield and is a preferred initial approach in horses with severe hindlimb lameness.

    Full Text Available The Neotropical Sasoninae Neodiplothele Mello-Leitão, 1917 is revised and now includes eight species. Neodiplothele can be distinguished from other Sasoninae by the absence of the posterior median spinnerets and differs Neotropical relatives as Cosmopelma by the absence of cuspules on coxae of leg I and Paracenobiopelma by the absence of cuspules on the labium. The male of N. irregularis Mello-Leitão, 1917 and N. picta Vellard, 1924 are described and illustrated for the first time. Neodiplothele leonardosi Mello-Leitão, 1939 is considered a junior synonym of N. irregularis. Five new species are described from Brazil: N. aureus sp. nov. from the states of Ceará, Rio Grande do Norte, Paraíba, and Minas Gerais, N. itabaiana sp. nov. from Sergipe, N. martinsi sp. nov. from Bahia, Espírito Santo, and Minas Gerais, N. indicattii sp. nov. from Espírito Santo, Minas Gerais, Rio de Janeiro, and São Paulo, N. caucaia sp. nov. from Ceará, Goiás, and Mato Grosso do Sul. Two informal groups are proposed based on genitalia morphology: irregularis group and picta group. An identification key and new distribution records for all known species are given.

The association of Becker's nevus with other cutaneous, musculoskeletal or maxillofacial anomalies has been called Becker's nevus syndrome. We report a case of a 16-year-old girl with a hyperpigmented macula which spread from her right anterolateral trunk to the inner part of her right thigh accompanied by ipsilateral mammary hypoplasia. The skin lesion started when the patient was seven years old when it was also noticed ipsilateral mammary hypoplasia. The histological exam confirmed the clinical hypothesis of Becker's nevus.

    Specific patterns of developmental adaptation of the proximal femur have been recognized in some sports. Gymnastics are characterized by repetitive axial loading and hip rotations in combination with extreme hip positions. It is unknown how and if these forces can affect an immature skeleton in the long term. We sought to evaluate this, by means of magnetic resonance imaging of the hip and groin of such elite asymptomatic athletes. We performed a case-control comparative MR imaging study of both hips and groin of 12 (7 male, 5 female) skeletally mature young (mean age 18.6 years) asymptomatic international level gymnasts with a minimum of 10 years' training with age-matched non-athletes. At the time of recruitment, none of the athletes had a recorded musculoskeletal complaint or injury in the anatomical area around the hip. The study showed that elite gymnasts share four common morphological characteristics on MRI that deviate from normal and are considered to be the result of adaptational changes to the specific sport: high centre-column-diaphysis angle (coxa valga140 on average), ligamentum teres hypertrophy, friction of the iliotibial band with oedema surrounding the greater trochanter, and a high incidence (62.5 %) of radiological appearances of ischiofemoral impingement. Our study showed that elite gymnasts share four common morphological characteristics on MRI that deviate from normal. These findings were in asymptomatic subjects; hence, radiologists and sports physicians should be aware of them in order to avoid unnecessary treatment. (orig.)

    Full Text Available O presente trabalho teve por objetivo investigar a modulação exercida pela temperatura ambiental sobre a cinética celular inflamatória experimentalmente induzida em Rana catesbeiana, rã-touro gigante. Para tanto, 120 espécimes pós-metamórficos foram mantidos a 6ºC e 24ºC e tratados pela transfixação do tecido muscular da coxa por fio de sutura ou injeção intramuscular de carragenina. Os resultados obtidos através de avaliações qualitativa e quantitativa do foco lesional mostraram que a baixa temperatura ambiental modula significativamente a evolução do processo inflamatório. Animais mantidos a 6ºC, em ambos os modelos, apresentaram números de células inflamatórias significativamente menores que os verificados a 24ºC, independentemente do tempo de avaliação. Por outro lado, algum fator pertencente aos mecanismos de defesa do hospedeiro não deve ter sido bloqueado pela temperatura, visto que a área de reação à injúria mostrou-se equivalente na maioria dos tempos pesquisados.

    Together with race, stature and age, sex is a main component of the biological identity. Thanks to its proportional correlation with parts of the human body, sex can be evaluated form the skeleton. The most accurate approach to determine sex by bone size is based on os coxae or skull. After natural disaster their presence can never be guaranteed, therefore the development of methods of sex determination using other skeletal elements can result crucial. Herein, sexual dimorphism in the human scapula is used to develop a two-variable discriminant function for sex estimation. We have enrolled 100 males and 100 females who underwent thoracic CT scan evaluation and we have estimated two scapular diameters. The estimation has been carried out by analyzing images of the scapulae of each patient after three dimensional post-processing reconstructions. The two-variable function allows to obtain an overall accuracy of 88% on the calibration sample. Furthermore, we have employed the mentioned function on a collection of 10 individual test sample from the collection of the "Museo di Anatomia Umana di Firenze" of the Università degli Studi di Firenze; sex has been correctly predicted on 9 skeletons.

    A malformed adult female specimen of Pycnogonum litorale (Pycnogonida) with a supernumerary leg in the right body half is described concerning external and internal structures. The specimen was maintained in our laboratory culture after an injury in the right trunk region during a late postembryonic stage. The supernumerary leg is located between the second and third walking legs. The lateral processes connecting to these walking legs are fused to one large structure. Likewise, the coxae 1 of the second and third walking legs and of the supernumerary leg are fused to different degrees. The supernumerary leg is a complete walking leg with mirror image symmetry as evidenced by the position of joints and muscles. It is slightly smaller than the normal legs, but internally, it contains a branch of the ovary and a gut diverticulum as the other legs. The causes for this malformation pattern found in the Pycnogonum individual are reconstructed in the light of extirpation experiments in insects, which led to supernumerary mirror image legs, and the "boundary model" for appendage differentiation.

    Full Text Available Nonunion of femoral neck fractures following primary fixation and neglected femoral neck fracture in young adults is a challenging task. Every effort should be directed toward hip joint salvage in these patients. Among different available options of hip salvage, nonvascularized fibular graft (NVFG osteosynthesis is simple, easy to perform, and a successful technique. In this review, the available literature on NVFG in neglected and nonunion femoral neck fractures has been analyzed. After review of 15 articles on NVFG, the average nonunion rate was estimated to be 7.86% (range 0-31%. Six articles that evaluated the preoperative and postoperative osteonecrosis reported improvement in 50% patients. The clinical and/or functional outcome was good to excellent in 56-96% patients following fibular osteosynthesis. Few complications such as coxa vara deformity, limb shortening, and intraarticular penetration of the graft or hardware have been reported. However, there are minimal donor site morbidities such as mild ankle pain, transient loss of toe flexors and extensors and transient lateral popliteal nerve palsy.

    During 2009, an outbreak of hand, foot, and mouth disease (HFMD) enrolled 490 people in Henan Province, causing the death of two children. In order to investigate the pathogens responsible for this outbreak and characterize their genetic characteristics, a total of 508 clinical specimens (stool, throat swab, and vesicle fluid) were collected from the Center for Disease Control and Prevention of Henan Province. Virological investigations (virus isolation, conventional reverse transcription PCR, and real-time reverse transcription PCR) and phylogenetic analysis were performed. It was found that human enterovirus 71 (EV71) was the main pathogen causing this outbreak, while Coxsackievirus A16 (CoxA16) played only a subsidiary role. Phylogenetic analysis of 24 EV71 isolates collected during the period from March 11 to July 24, 2009 showed that they belonged to subgenotypes C4 and C5. Our study for the first time characterizes the epidemiology of HFMD and EV71 infection in Henan Province in 2009 and provides the first direct evidence of the genotype of EV71 circulating in Henan Province at that time. Our study should facilitate the development of public health measures for the control and prevention of HFMD and EV71 infection in at-risk individuals in China.

    Full Text Available Background: The cataract (Cataracta senilis is the most frequent eye disease of elderly people worldwide. In Germany, the cataract operation - with currently 450,000 interventions each year the most frequent operation in ophthalmology – can be seen as routine surgery. The age related macular degeneration (AMD is a further one of the most common, age-related eye diseases and the most frequent cause of blindness of elderly people in industrial nations. Due to demographic changes an increasing number of patients will suffer from cataract and AMD at the same time. This coincidence leads to a greater interest in the question of a mutual influence of both diseases, respectively their therapies, on each other. Objectives: The aim of this report was the evaluation of the medical and health economic effects of cataract operations on the development and progression of an age related macular degeneration (AMD. It was differentiated between first manifestations of AMD, progression of early stages of AMD and influence on further impairment in late stages of AMD. Methods: The relevant publications for this report were identified by DIMDI via structured database enquiry as well as common, self-made enquiry and were evaluated, based on the criteria of evidence based medicine. The present report included German and English literature published since 1983. Results: The database enquiry generated a record of 2769 issue-related publications. Eight medical publications were eligible for analysis in the course of the present HTA report. No relevant studies on health economical, ethical, social or legal issues could be included. Three epidemiological cohort studies provided some evidence for a promoting influence of cataract extractions on the progression of early types of AMD. Two of the epidemiological studies assessed the risk of first manifestation of AMD after cataract extraction. Both came up with up with increased incidences that did not reach statistical

    Full Text Available Today, the definition “glaucoma” combines a number of eye pathologies that lead to irreversible blindness, and therefore is difficult disabling disease. Glaucoma occurs in people of working age, so this problem is not only medical, but also social, because it causes disability in substantial economic costs not only for individual patients, but also for the whole country – patients become unable to work. Gender features of glaucoma are also contradictory. In European literature the basic idea is that men are more likely to suffer from glaucoma than women. Such studies have not been conducted in the Podillya region of Ukraine, that makes impossible to design a reliable global data to estimate the prevalence of glaucoma in different age groups for persons living in Vinnitsa region. Therefore, the aim of the study was a retrospective analysis of medical records of patients in Eye Microsurgery Department of Vinnitsa Regional Clinical Hospital for the period 2008-2012 years for determining the gender and age characteristics. Materials and methods 1418 patients with primary open-angle glaucoma (841 men and 577 women aged 14 to 92 years (mean age 67,12 ± 7,64, which were treated in the Eye Microsurgery Department, took part in the study. For the purpose of the study they were divided into two groups: I – male patients with glaucoma, II – female patients with glaucoma. Each group was divided into 7 subgroups according to the ontogenesis scheme: A – teens, B – youth, C – I adulthood age, D – II adulthood age, E – elderly age, F – senily age and G – centenarians. Thus was allocated 12 research groups. Results The structure of the incidence of glaucoma is 59.31% in men and 40.69% in women. Incidence of glaucoma is highest in the IE group and is 34.98%. The group IIE incidence is lower – 35.32%. In the group D the incidence of glaucoma among men and women was very different (13.89% and 2.89%, respectively. It should also be noted

    The cause of hip disorder in cerebral palsy (CP) has been thought to involve muscle imbalance, flexion, and adduction contracture of the hip joint, acetabular dysplasia, and femoral growth abnormalities. The aim of this study was to quantitatively evaluate the 3-dimensional femoral geometry and subluxation/dislocation of the hip in spastic CP using 3D-CT reconstructed images of the pelvis and the femur, focusing on the femoral growth abnormalities in CP. Between June 2006 and September 2009, 186 hips in 93 bilateral spastic CP patients, including spastic diplegia (SD) in 73 patients and spastic quadriplegia (SQ) in 20 patients, who had not received any surgical treatment, were investigated using 3D-CT at our hospital. There were 59 boys and 34 girls with an average age of 5.3 years (range: 2.6 to 6.8 y). As an index for the femoral geometry, the neck-shaft angle, the femoral anteversion, and the femoral offset were 3-dimensionally measured. The center of the acetabulum and the femoral head were determined to calculate the CT migration percentage as the distance between these centers divided by the femoral head diameter. To elucidate the factors related to hip subluxation/dislocation, the relationships between the neck-shaft angle, the femoral anteversion, the femoral offset, and the CT migration percentage were investigated. The mean neck-shaft angle was 150.4+/-9.4 degrees (range: 129.4 to 173.2 degrees). The mean femoral anteversion was 44.4+/-13.6 degrees (range: 5.8 to 84.0 degrees). The mean CT migration percentage was 22.4+/-22.7% (range: 3 to 129%). There was positive correlation between the CT migration percentage and the neck-shaft angle (r=0.49). Hips with large CT migration percentage tended to show coxa valga. There was an inverse correlation between the neck-shaft angle and the femoral offset (r=-0.90), but no correlation between the CT migration percentage and the femoral anteversion (r=0.26), between the femoral offset and the femoral anteversion (r

    Full Text Available A bactéria Rubrivivax gelatinosus tem sido utilizada experimentalmente no tratamento despoluente de efluentes industriais de abatedouros de aves e peixes, originando uma biomassa contendo pigmentos carotenoides, substâncias que possuem a capacidade de conferir cor aos alimentos e proteger contra reações oxidativas. Este trabalho teve por objetivo verificar o efeito da biomassa de R. gelatinosus adicionada à alimentação de frangos de corte sobre o desempenho animal e a cor de carne e pele. Duzentos pintos machos Cobb 500 foram distribuídos aleatoriamente em 20 boxes para receber, do 36º ao 45º dia de criação, quatro tratamentos com diferentes quantidades de biomassa na ração (T1 [controle] - 0g/kg; T2 - 1g/kg; T3 - 2g/kg; T4 - 3g/kg, em cinco repetições. As pesagens de aves e rações para a análise de desempenho foram feitas no início da criação e ao fim de cada período de crescimento. Ao final do experimento (45 dias, 20 aves de cada tratamento foram abatidas para a determinação da cor objetiva (L - luminosidade, C - saturação, h - tom em pele e carne de peito e coxa. Os resultados obtidos foram submetidos à ANOVA, teste t para a comparação múltipla de médias e análise de regressão com nível de significância de 5%. O ganho de peso e o consumo das aves não diferiram estatisticamente entre si (P>0,05, enquanto o índice de conversão alimentar foi superior para o T1. A luminosidade da carne e da pele aumentou significativamente nos tratamentos que receberam a biomassa. O tom da cor em carne e pele aumentou em direção ao amarelo até a concentração de 2g de biomassa por kg de ração, ao passo que, na concentração de 3g/kg, o aumento foi em direção à tonalidade vermelha. Somente na carne da coxa a saturação da cor sofreu influência da presença da biomassa na dieta. Concluiu-se que, até a proporção de 3g/kg, a biomassa não prejudicou o desempenho e foi eficiente em pigmentar a pele e a carne de

  18. The Omo-Kibish I pelvis.

    2017-07-01

    Omo-Kibish I (Omo I) from southern Ethiopia is the oldest anatomically modern Homo sapiens skeleton currently known (196 ± 5 ka). A partial hipbone (os coxae) of Omo I was recovered more than 30 years after the first portion of the skeleton was recovered, a find which is significant because human pelves can be informative about an individual's sex, age-at-death, body size, obstetrics and parturition, and trunk morphology. Recent human pelves are distinct from earlier Pleistocene Homo spp. pelves because they are mediolaterally narrower in bispinous breadth, have more vertically oriented ilia, lack a well-developed iliac pillar, and have distinct pubic morphology. The pelvis of Omo I provides an opportunity to test whether the earliest modern humans had the pelvic morphology characteristic of modern humans today and to shed light onto the paleobiology of the earliest humans. Here, we formally describe the preservation and morphology of the Omo I hipbone, and quantitatively and qualitatively compare the hipbone to recent humans and relevant fossil Homo. The Omo I hipbone is modern human in appearance, displaying a moderate iliac tubercle (suggesting a reduced iliac pillar) and an ilium that is not as laterally flaring as earlier Homo. Among those examined in this study, the Omo I ischium is most similar in shape to (but substantially larger than) that of recent Sudanese people. Omo I has features that suggest this skeleton belonged to a female. The stature estimates in this study were derived from multiple bones from the upper and lower part of the body, and suggest that there may be differences in the upper and lower limb proportions of the earliest modern humans compared to recent humans. The large size and robusticity of the Omo I pelvis is in agreement with other studies that have found that modern human reduction in postcranial robusticity occurred later in our evolutionary history.

No entanto, sua anatomia ainda é pouco estudada. Para verificar a hipótese com qual espécie e/ou grupo de primatas os macacos-prego compartilham mais características, o objetivo deste trabalho foi estudar os nervos pélvicos do Sapajus e compará-los com dados da literatura anatômica sobre os seres humanos, chimpanzés e babuínos, considerando aspectos como origem, trajetória e estruturas inervadas. Foi observado que existem grandes variações nos nervos pélvicos entre os primatas estudados aqui, quais sejam, 1 o problema da posição anatômica, i.e., alguns primatologistas consideram a posição anatômica humana para os primatas, outros consideram a posição anatômica animal, e a opção por um ou outro não é clara nos textos; 2 o problema dos membros pélvicos em primatas não humanos serem lateralizados e semi-fletidos em relação aos seres humanos modernos; 3 o problema da ausência, nos seres humanos modernos, de alguns músculos da coxa em relação aos outros primatas como o escansório e o iliosquiofemoral; e 4] o problema da diferença do número de vértebras nos primatas estudados aqui, inclusive com diferenças para a mesma espécie citadas por diferentes autores tanto para chimpanzés como para macacos-prego.

    Full Text Available Hip disorders in a pediatric population are a diagnostic challenge. The aim of the study is to assess the role of magnetic resonance imaging (MRI in the evaluation of non-traumatic hip disorders in a series of Egyptian patients and to review the literature on the most common hip conditions. Seventy two consecutive patients [40 males (55.6% and 32 females (44.4] with acute onset of hip complaints unrelated to trauma or falls were recruited. All patients underwent an initial full clinical assessment and blood tests as well as contrast enhanced MRI of both hips. The most common diagnosis in this group of Egyptian patients was transient synovitis in 29 (40.3% cases, followed by seronegative enthesopathy and arthropathy syndrome in 8 (11.1%, septic arthritis in 10 (13.9%, tuberculous arthritis in 4 (5.6%, sickle-cell disease in 7 (9.7%, complicated with septic arthritis in 3 (4.2%, transient bone marrow edema (BME in 3 (4.2%, osteomyelitis in 2 (2.8%, osteosarcoma in 2 (2.8%, sciatic nerve injury in 1 (1.4%, leukemia with BME in 1 (1.4%, coxa vara of both hips and L5/S1 facet joint ankylosis in 1 (1.4%, and a benign bone cyst in 1 (1.4%. MRI studies showed hip effusion in a total of 51 patients (70.8%, joint space narrowing in 9 (12.5%, and BME in 15(20.8%. MRI is a sensitive tool for assessing hip disorders in a pediatric population and can play an important role in both diagnosis and management of different hip disorders, irrespective of the underlying pathology.

    Lameness, thoracolumbosacral pain and reduced range of motion (ROM) often coexist; better understanding of their relationship is needed. The objectives were to determine if thoracolumbosacral movement of horses changes when pain causing lameness is improved by diagnostic analgesia. We hypothesised that reduction of lameness will increase ROM of the thoracolumbosacral region. Thirteen horses with different types of hind limb lameness were trotted in straight lines and lunged on a 10m diameter circle on left and right reins before and after lameness was subjectively substantially improved by diagnostic analgesia. Inertial sensor data were collected from the withers, thirteenth (T13) and eighteenth thoracic (T18) vertebrae, third lumbar (L3) vertebra, tubera sacrale (TS), left and right tubera coxae. ROM of flexion-extension, axial rotation, lateral bending, dorsoventral, lateral-lateral motion and vertical movement symmetry were quantified at each thoracolumbar site. Hiphike difference (HHD), maximum difference (MaxDiff) and minimum difference (MinDiff) for the pelvic sensors were measured. Percentage changes for before and after diagnostic analgesia were calculated; mean±standard deviation (SD) or median [interquartile range] were determined. Associations between the change in pelvic versus thoracolumbar movement symmetry after each local analgesic technique were tested. After resolution of lameness, HHD decreased by 7% [68%] (P=0.006). The MinDiff decreased significantly by 33% [61%] (P=0.01), 45±13% (P=0.005) and 52±23% (P=0.04), for TS, L3 and T18, respectively. There was significantly increased ROM in flexion-extension at T13, in axial rotation at T13, T18, L3 and in lateral-lateral ROM at L3. Thoracolumbosacral asymmetry and reduced ROM associated with lameness were both altered immediately by improvement in lameness using diagnostic analgesia. Copyright © 2017 Elsevier Ltd.

    Full Text Available Background: Thoracolumbar kyphosis has been considered as the first presenting deformity and is often a key diagnostic clue noted in children with mucopolysaccharidosis (MPS type IV (Morquio′s syndrome. However, we observed that the progressive irregularities of the epiphyses of the long bones were the most prominent skeletal pathology, causing effectively the development of diverse forms of lower limbs deformities with extreme variation in age of onset. Materials and Methods: Ten patients (seven children and three adults with an average age of 15 years have been enrolled in this study. Age of diagnosis of MPS IVA has a variable age of onset and a MISLEADING rate of severity. Hip dislocations, genu valgum, protrusio acetabuli and osteoarthritis were the most common lower limbs deformities in these patients. Clinical and radiographic phenotypes were the baseline tools of documentation. Urinary screening and genotypic characterizations have been applied accordingly. Results: Combined pelvic and femoral procedures for hip dislocation, epiphysiodeses and supracondylar osteotomy for genu valgum and hip arthroplasty for protrusio acetabuli have been performed. All patients manifested insufficient activity of N-acetylgalactosamine-6-sulphate sulphatase, an enzyme that degrades keratin sulphate and chondroitin-6 sulphate. Conclusion: The extensive clinical heterogeneity contributed significantly in the delay in establishing the diagnosis particularly in adult patients with MPS IV. The epiphyseal irregularities of the long bones and the progressive flattening pathology of MPS IV A were the reason to falsely diagnose some patients as spondyloepiphyseal dysplasia congenital and/or tarda. Proximal femoral osteotomy, realignment osteotomy and total hip arthroplasty have been performed for coxa vara, genu valgum and protrusio acetabuli, respectively, in children and adult group of patients. The importance of early diagnosis on MPS IV A is to receive enzyme

    Purpose: To assess acetabular and femoral hip joint cartilage with three-dimensional (3D) delayed gadolinium-enhanced magnetic resonance imaging (dGEMRIC) in patients with degeneration of hip joint cartilage and asymptomatic controls with morphologically normal appearing cartilage. Methods and materials: A total of 40 symptomatic patients (18 males, 22 females; mean age: 32.8 {+-} 10.2 years, range: 18-57 years) with different hip joint deformities including femoroacetabular impingement (n = 35), residual hip dysplasia (n = 3) and coxa magna due to Legg-Calve-Perthes disease in childhood (n = 2) underwent high-resolution 3D dGEMRIC for the evaluation of acetabular and femoral hip joint cartilage. Thirty-one asymptomatic healthy volunteers (12 males, 19 females; mean age: 24.5 {+-} 1.8 years, range: 21-29 years) without underlying hip deformities were included as control. MRI was performed at 3 T using a body matrix phased array coil. Region of interest (ROI) analyses for T1{sub Gd} assessment was performed in seven regions in the hip joint, including anterior to superior and posterior regions. Results: T1{sub Gd} mapping demonstrated the typical pattern of acetabular cartilage consistent with a higher glycosaminoglycan (GAG) content in the main weight-bearing area. T1{sub Gd} values were significantly higher in the control group than in the patient group whereas significant differences in T1{sub Gd} values corresponding to the amount of cartilage damage were noted both in the patient group and in the control group. Conclusions: Our study demonstrates the potential of high-resolution 3D dGEMRIC at 3 T for separate acetabular and femoral hip joint cartilage assessment in various forms of hip joint deformities.

    A new cyclopoid species of the genus Neocyclops Gurney, 1927 is described. Type specimens were collected from a beach on south-western coast of the Korean Peninsula by rinsing intertidal coarse sandy sediments. Neocyclops hoonsooi sp. n. is most characteristic in showing the conspicuous chitinized transverse ridges originating from the medial margins of the coxae of all swimming legs. The new species is most similar to Neocyclops vicinus, described from the Brazilian coast, and Neocyclops petkovskii, from Australia. All three species share a large body size (more than 750 µm long), the presence of an exopodal seta on the antenna, two setae on the mandibular palp, the same seta/spine armature on the third endopodal segment of leg 3 (3 setae + 3 spines), and the fairly long inner distal spine on the third endopodal segment of the female leg 4. However, Neocyclops hoonsooi sp. n. differs from both species by the much shorter caudal rami (less than 1.7 times as long as wide) and the shorter dorsal caudal seta VII. Furthermore, Neocyclops hoonsooi is clearly distinguished from Neocyclops vicinus by the 10-segmented antennule (vs 12 segments in Neocyclops vicinus), and from Neocyclops petkovskii by the elongate inner distal spine on leg 5 exopod and the 3-segmented leg 5 in male (vs 4-segmented in Neocyclops petkovskii). A tabular comparison of characters separating Neocyclops hoonsooi from its closest allies and a key to Neocyclops species from the Indo-Pacific Ocean are provided. This is the first record of the genus Neocyclops from the northern Pacific.

    Equine movement symmetry is changed when turning, which may induce alterations in thoracolumbosacral kinematics; however, this has not previously been investigated. Our objectives were to document thoracolumbar movement in subjectively sound horses comparing straight lines with circles on both reins and to relate these observations to the objectively determined symmetry/asymmetry of hindlimb gait. Fourteen non-lame horses were assessed prospectively in a non-random, cross-sectional survey. The horses were trotted in straight lines and lunged on both reins and inertial sensor data collected at landmarks: withers, T13 and T18, L3, tubera sacrale, and left and right tubera coxae. Data were processed using published methods; angular motion range of motion (ROM; flexion-extension, axial rotation, lateral bending) and translational ROM (dorsoventral and lateral) and symmetry within each stride were assessed. The dorsoventral movement of the back exhibited a sinusoidal pattern with two oscillations per stride. Circles induced greater asymmetry in dorsoventral movement within each stride (mean ± standard deviation, up to 9 ± 6%) compared with straight lines (up to 6 ± 6%). The greatest amplitude of dorsoventral movement (119 ± 14 mm in straight lines vs. 126 ± 20 mm in circles) occurred at T13. Circles induced greater flexion-extension ROM (>1.3°; P = 0.002), lateral bending (>16°; P 16 mm; P = 0.002) compared with straight lines. Circles induced a movement pattern similar to an inside hindlimb lameness, which was significantly associated with the circle-induced greater asymmetry of dorsoventral movement of the thoracolumbar region (P = 0.03). Moving in a circle induces measurable changes in thoracolumbar movement compared with moving in straight lines, associated with alterations in the hindlimb gait. Copyright © 2017 Elsevier Ltd.

    We report a nearly complete lumbar spine from the Middle Pleistocene site of the Sima de los Huesos (SH) that is assigned to the previously published SH male Pelvis 1 [Arsuaga JL, et al. (1999). Nature 399: 255-258]. The "SH Pelvis 1 individual" is a unique nearly complete lumbo-pelvic complex from the human Middle Pleistocene fossil record, and offers a rare glimpse into the anatomy and past lifeways of Homo heidelbergensis. A revised reconstruction of Pelvis 1, together with the current fossil evidence, confirms our previous hypothesis that the morphology of this pelvis represents the primitive pattern within the genus Homo. Here we argue that this primitive pattern is also characterized by sexual dimorphism in the pelvic canal shape, implying complicated deliveries. In addition, this individual shows signs of lumbar kyphotic deformity, spondylolisthesis, and Baastrup disease. This suite of lesions would have postural consequences and was most likely painful. As a result, the individual's daily physical activities would have been restricted to some extent. Reexamination of the age-at-death agrees with this individual being over 45 y old, relying on the modern human pattern of changes of the articular surfaces of the os coxae. The presence of degenerative pathological lesions and the advanced age-at-death of this individual make it the most ancient postcranial evidence of an aged individual in the human fossil record. Additional nonpathological SH lumbo-pelvic remains are consistent with previous hypotheses, suggesting a less-pronounced sagittal spinal curvature in Neandertals compared with Homo sapiens.

    Abstract Two new species of the freshwater cyclopoid genera Eucyclops are described, Eucyclops tziscao sp. n. and E. angeli sp. n. Both species belong to the serrulatus-group defined by morphological features such as: the presence of distal spinules or hair-like setae (groups N1 and N2) on frontal surface of antennal basis; the fourth leg coxa with a strong inner spine that bears dense setules on inner side, yet proximally naked (large gap) on outer side; and a 12-segmented antennule with smooth hyaline membrane on the three distalmost segments. Eucyclops tziscao sp. n. is morphologically similar to E. bondi and E. conrowae but differs from these species in having a unique combination of characters, including a caudal ramus 4.05±0.25 times as long as wide, lateral seta of Enp3P4 modified as a strong, sclerotized blunt seta, coxal spine of fourth leg with inner spinule-like setules distally, and sixth leg of males bearing a strong and long inner spine 2.3 times longer than median seta. Eucyclops angeli sp. n. can be distinguished by an unique combination of morphological features: the short caudal ramus; the long spine on the sixth antennular segment of A1; the presence of one additional group of spinules (N12’) on the caudal surface of A2; the presence of long setae in females, or short spinules in males on the lateral margin of fourth prosomite; the strong ornamentation of the intercoxal sclerite of P4, specially group I modified as long denticles; the distal modified setae of Exp3P3 and Exp3P4 in females and males; and the short lateral seta of P5. Finally, we report on a new record of E. festivus in México, and add data on morphology of the species. PMID:24294085

    The clinical signs, laboratory data, results of nuclear scintigraphy and radiographic examination of five horses with vertebral body osteomyelitis are described together with response to treatment. Three horses were less than five months of age. Four horses demonstrated hindlimb paresis and in three a focus of pain in the thoracolumbar region could be identified. An umbilical abscess, a caudal lobe lung abscess and a patent urachus were considered primary niduses of infection in each of three horses. Leucocytosis, neutrophilia, anaemia and elevated fibrinogen were the most consistent laboratory abnormalities. Nuclear scintigraphy was performed in three horses and identified the site of the vertebral lesion which was subsequently evaluated radiographically. In the other two horses radiographic examination in the region of areas of focal pain identified a lesion. Radiographic abnormalities included compression fractures of vertebral bodies (two), proliferative new bone (three) and soft tissue swelling ventral to a vertebral body (one). Two horses, including one with a compression fracture of the second lumbar vertebra, received parenteral antimicrobial therapy for 40 and 74 days, respectively. When re-examined six months later they showed no neurological abnormalities. The other three horses failed to respond to antimicrobial treatment and were humanely destroyed. The horse with a lung abscess also had an abscess cranial to the right tuber coxae which extended into the vertebral bodies of the third and fourth lumbar vertebrae from which Streptococcus zooepidemicus was cultured. A horse with proliferative new bone on the ventral aspect of the fifth and sixth thoracic vertebrae had a mediastinal mass associated with these vertebrae and fungal granulomas, from which Aspergillus species was cultured, in the heart and aorta, trachea, spleen and kidney. The horse with a patent urachus and soft tissue swelling ventral to the vertebral body of the 12th thoracic vertebra

Generally occurring in full-term neonates or during the first four weeks after a traumatic delivery, the disorder is characterized by the appearance of hard subcutaneous nodules or plaques on the trunk, buttocks or thighs. It is normally a benign and transient condition, although it may be complicated by hypocalcemia, which requires close monitoring until skin lesions are cured. The authors describe two cases of subcutaneous fat necrosis of the newborn, one occurring in a full-term neonate and the other in a premature newborn, both related to traumatic delivery and fetal distress

    Recessive mutations in TMEM38B cause type XIV osteogenesis imperfecta (OI) by dysregulating intracellular calcium flux. Clinical and bone material phenotype description and osteoblast differentiation studies. Natural history study in pediatric research centers. Eight patients with type XIV OI. Clinical examinations included bone mineral density, radiographs, echocardiography, and muscle biopsy. Bone biopsy samples (n = 3) were analyzed using histomorphometry, quantitative backscattered electron microscopy, and Raman microspectroscopy. Cellular differentiation studies were performed on proband and control osteoblasts and normal murine osteoclasts. Type XIV OI clinical phenotype ranges from asymptomatic to severe. Previously unreported features include vertebral fractures, periosteal cloaking, coxa vara, and extraskeletal features (muscular hypotonia, cardiac abnormalities). Proband lumbar spine bone density z score was reduced [median -3.3 (range -4.77 to +0.1; n = 7)] and increased by +1.7 (1.17 to 3.0; n = 3) following bisphosphonate therapy. TMEM38B mutant bone has reduced trabecular bone volume, osteoblast, and particularly osteoclast numbers, with >80% reduction in bone resorption. Bone matrix mineralization is normal and nanoporosity low. We demonstrate a complex osteoblast differentiation defect with decreased expression of early markers and increased expression of late and mineralization-related markers. Predominance of trimeric intracellular cation channel type B over type A expression in murine osteoclasts supports an intrinsic osteoclast defect underlying low bone turnover. OI type XIV has a bone histology, matrix mineralization, and osteoblast differentiation pattern that is distinct from OI with collagen defects. Probands are responsive to bisphosphonates and some show muscular and cardiovascular features possibly related to intracellular calcium flux abnormalities. Copyright © 2017 Endocrine Society

    l-Ascorbic acid (AsA) and its metabolic precursors give rise to oxalic acid (OxA) found in calcium oxalate crystals in specialized crystal idioblast cells in plants; however, it is not known if AsA and OxA are synthesized within the crystal idioblast cell or transported in from surrounding mesophyll cells. Isolated developing crystal idioblasts from Pistia stratiotes were used to study the pathway of OxA biosynthesis and to determine if idioblasts contain the entire path and are essentially independent in OxA synthesis. Idioblasts were supplied with various 14C-labeled compounds and examined by micro-autoradiography for incorporation of 14C into calcium oxalate crystals. [14C]OxA gave heavy labeling of crystals, indicating the isolated idioblasts are functional in crystal formation. Incubation with [1-14C]AsA also gave heavy labeling of crystals, whereas [6-14C]AsA gave no labeling. Labeled precursors of AsA (l-[1-14C]galactose; d-[1-14C]mannose) also resulted in crystal labeling, as did the ascorbic acid analog, d-[1-14C]erythorbic acid. Intensity of labeling of isolated idioblasts followed the pattern OxA > AsA (erythorbic acid) > l-galactose > d-mannose. Our results demonstrate that P. stratiotes crystal idioblasts synthesize the OxA used for crystal formation, the OxA is derived from the number 1 and 2 carbons of AsA, and the proposed pathway of ascorbic acid synthesis via d-mannose and l-galactose is operational in individual P. stratiotes crystal idioblasts. These results are discussed with respect to fine control of calcium oxalate precipitation and the concept of crystal idioblasts as independent physiological compartments. PMID:11161021

O diagnóstico é clínico, por vezes auxiliado por exames de imagem e biópsia. Descreve-se o caso de um recém-nascido de termo, fruto de uma gestação vigiada com ecografias obstétricas sem alterações, que apresentava ao nascimento, na face anterior da coxa esquerda, uma massa de 5x4,5cm, mole, depressível, acinzentada, com algumas telangiectasias periféricas e halo periférico esbranquiçado, sem frémito palpável ou ulceração. Hemodinamicamente estável, sem trombocitopenia. A ecografia e a ressonância magnética apoiaram a suspeita clinica de RICH, que foi corroborada imunohistologicamente. Após 15 meses verificou- -se regressão espontânea e completa do tumor.

    Full Text Available A giant congenital melanocytic nevus represents a rare condition. The halo phenomenon may be seen in congenital or acquired melanocytic nevi. In the literature, association of halo nevus and giant congenital melanocytic nevus is rare and the association of both with vitiligo even more rare. A 75-yearold woman at first consultation complained of a hyperchromic bluish-brown hairy macula on the lower back, buttocks and thighs present since birth and an achromic halo of onset three years ago. The histological features were consistent with congenital melanocytic nevus and halo nevus, respectively. After two years the patient developed achromic areas in normal skin, histologically consistent with vitiligo. The authors emphasize the rarity of this triple combination, the patient's age and the absence of malignant degeneration to date.Nevo melanocitico congênito gigante constitui uma condição rara.

    Full Text Available A administração de medicamentos por via intramuscular (IM é um procedimento desenvolvido pela enfermagem; a seleção das regiões a serem utilizadas deve levar em consideração as vantagens e desvantagens de cada um dos locais. Fez-se um levantamento das regiões mais indicadas ou utilizadas pelos enfermeiros-docentes e enfermeiros-hospitalares e do local que indicaram para a punção com a agulha; foi verificado se havia alguma diferenciação na escolha da região de acordo com o sexo e idade do cliente e qual era o conhecimento sobre as contra-indicações e as complicações na utilização de cada uma das regiões para aplicação de injeção IM. Dos dados levantados, concluiu-se que as regiões deltóide, dorso-glútea e face ântero-lateral da coxa são as preferencialmente utilizadas por ambos os grupos, tendo sido constatado que a sua localização nem sempre foi anatomicamente correta e para escolha da região cerca de 80% da população investigada levou em consideração a idade do cliente. Apenas algumas contraindicações e complicações mencionadas foram concordantes com as analisadas pelos autores consultados; ressalta-se que a região ventroglútea, tida como a mais segura e adequada por estes autores, foi a menos mencionada como utilizada por ambos os grupos de enfermeiros.

    Full Text Available There is substantial controversy in literature about human dermatomes. We studied L4, L5, and S1 inferior limb dermatomes by comparing clinical signs and symptoms with conduction studies, electromyographical data, neurosurgical findings, and imaging data from computerized tomography (CT or magnetic resonance imaging (MRI. After analyzing 60 patients, we concluded that L4 is probably located in the medial aspect of the leg, L5 in the lateral aspect of the leg and foot dorsus, and S1 in the posterior aspect of the backside, tight, leg and plantar foot skin. This is the first time that these human dermatomes have been evaluated by combined analysis of clinical, electromyographical, neurosurgical, and imaging data.Há controvérsia na literatura sobre os dermátomos humanos. Estudamos dermátomos do membro inferior comparando sinais e sintomas com estudos eletromiográficos, de imagem e achados cirúrgicos. Analisando 60 pacientes, concluímos que o dermátomo L4 provavelmente está localizado na região medial da perna, o dermátomo L5 na região lateral da perna e dorso do pé, e o dermátomo S1 na nádega, região posterior da coxa e da perna e na região plantar. Este é o primeiro estudo que os dermátomos do membro inferior foram analisados através de dados clínicos, eletromiográficos, imagem e achados cirúrgicos.

    The Legg-Calve-Perthes disease is an idiopathic avascular necrosis of the hip during early childhood. It is characterized by different stages with the main risk of persisting hip deformation, dysfunction of the joint movement, and the potential for early osteoarthritis. For the evaluation of prognosis and therapy planning patients age and extent of the necrotic area of the epiphysis are important factors. For an early diagnosis and sufficient therapy all radiological efforts have to be performed. MR imaging is an ideal method for the assessment of osteonecrotic changes of the Morbus Perthes. Compared to plain radiography by MR imaging pathologic alterations can be detected earlier and with higher specificity. However, conventional radiograms have to be still used as basic imaging modality. Nowadays x-rays and MR imaging should be the main methods for the evaluation of children suffering from Perthes disease. (orig.) [German] Beim Morbus Perthes handelt es sich um eine idiopathische Osteonekrose des Hueftgelenks im fruehkindlichen Alter (3.-12. Lebensjahr). Das Hauptrisiko dieser selbstlimitierenden Erkrankung mit suffizienter Reparatur und charakteristischem stadienhaftem Verlauf ist eine Defektheilung mit deformiertem Hueftkopf (Coxa magna) und sekundaer dysplastischer Pfanne. Diese praearthrotische Deformitaet fuehrt zur Einschraenkung der Hueftfunktion und einer fruehzeitigen Koxarthrose. Zur Abschaetzung der Prognose und Therapieplanung spielen Alter des Patienten bei Krankheitsbeginn sowie Groesse und Lokalisation des Nekroseareals eine entscheidende Rolle. Es ist somit augenscheinlich, dass alle radiologischen Register gezogen werden muessen, um eine moeglichst fruehe Diagnose und eine suffiziente Stadieneinteilung als Voraussetzung fuer eine risikoadaptierte Therapie zu gewaehrleisten. Die MRT eignet sich in idealer Weise zur Beurteilung ischaemischer Knochenmarkveraenderungen im Rahmen des Morbus Perthes. Verglichen mit dem konventionellen Roentgen ist die

    Full Text Available Resumo A rigidez da parede venosa pode aumentar em síndromes em que há uma redução da quantidade de elastina, ocasionando malformações venosas mesmo em indivíduos que possuem mosaicismo para tais síndromes. Casos com apresentação de afecções colagenosas em áreas delimitadas não foram descritos na literatura. O paciente apresentava lesão bem delimitada em região anteromedial da coxa com aumento de elasticidade e presença de vasos tortuosos apenas no local da lesão, não apresentando nenhuma síndrome colagenosa. Foi realizada uma biópsia que evidenciou alterações em relação ao padrão das fibras elásticas e proliferação de vasos sanguíneos. A malformação venosa foi tratada satisfatoriamente com embolização. As doenças do colágeno causam hiperextensibilidade cutânea, o que provoca flacidez e propicia traumas. As colagenoses bem delimitadas são raras, pois geralmente esse grupo de doenças envolve acometimento sistêmico. As malformações vasculares podem ocorrer em diversas doenças do colágeno, mas de forma generalizada e não localizada, e uma explicação para isso seria o mosaicismo genético.

    Full Text Available O objectivo do presente estudo foi avaliar o comportamento da força muscular e a participação dos indicadores de hipertrofia, nos ganhos de força após 32 semanas de treinamento com pesos (TP, prescrito por zona alvo de repetições máximas, em mulheres na pós-menopausa. Participaram desta pesquisa 14 mulheres saudáveis e não ativas fisicamente. O TP teve frequência semanal de três vezes, em dias alternados. A composição corporal foi mensurada pela técnica das dobras cutâneas. Os indicadores de hipertrofia foram representados pela massa magra total e regional: área muscular do braço (AMB e coxa (AMC. A força muscular foi avaliada pelo teste de uma repetição máxima nos exercícios leg press horizontal e rosca direta. Para análise estatística foi utilizado o teste de Friedman. Os resultados mostraram que a força muscular apresentou aumentos graduais e significantes durante a intervenção, que houve aumento da AMB e não houve diferença nos valores de AMC. A rosca direta mostrou forte associação com a AMB durante todos os momentos do estudo. Já o leg press pareceu estar mais efetivamente associado ao componente neural de ganhos de força, visto que a AMC não apresentou modificações significantes. Após 32 semanas de TP a força muscular aumentou significantemente, independentemente dos ganhos de massa magra.

    Posterior hip impingement is a recently-identified cause of hip pain. The purpose of this study is to characterise posterior femoroacetabular and ischiofemoral impingement and identify its predisposing morphologic traits. Two hundred and six cadaveric hips were randomly selected and taken through controlled motion in two pure axes associated with posterior hip impingement: external rotation (through the mechanical axis) and adduction (coronal plane). The range of motion and location of impingement was noted for each specimen. Morphologic traits including femoral/acetabular version, and true neck-shaft angle (TNSA) were also measured. External rotation impingement occurred between the femoral neck and acetabulum in 83.0% of hips, and between the lesser trochanter and ischial tuberosity in 17.0%. Adduction impingement occurred between the lesser trochanter and ischial tuberosity in 78.6% of hips, and between the femoral neck and acetabulum in 21.4%. Multiple regression revealed that increased femoral/acetabular version predicted earlier external rotation and adduction impingement. Unstandardised betas ranging from -0.39 to -0.64 reflect that each degree of increased femoral/acetabular version individually accounts for a loss of external rotation or adduction of approximately half a degree before impingement ( p < 0.001 for each). Increased TNSA was associated with earlier adduction impingement only (unstandardised beta -0.35, p = 0.005). Relative femoral/acetabular anteversion was associated with earlier posterior hip impingement. Coxa valga was associated with earlier adduction impingement, but protective against external rotation impingement. These findings highlight the importance of monitoring correction during femoral/acetabular osteotomies, as overcorrection of retroversion may predispose to earlier posterior impingement.

    Full Text Available As cirurgias radicais para tratamento dos tumores da cintura pélvica e escapular (hemipelvectomias e desarticulações interescapulotorácicas constituem-se, em geral, em procedimentos extensos com grandes áreas de perda de substância local após ressecção do tumor. A utilização do retalho que inclui toda a musculatura anterior e posterior da coxa após dissecção do fêmur, pediculado pelos vasos femorais superficiais, foi descrita apenas uma vez na literatura. O retalho similar utilizando toda a musculatura anterior e posterior do braço após dissecção do úmero, pediculado pelos vasos subclávios para reconstrução após desarticulação interescapulotorácica, não apresenta relatos. Descrevemos dois casos - um de hemipelvectomia e outro de desarticulação interescapulotorácica - utilizando estes dois retalhos para fechamento do defeito.Radical surgeries for treatment of scapular and pelvic girdle tumors (hemipelvectomy and interscapulothoracic amputation are generally extended procedures, with large areas of local tissue loss after tumor resection. The use of a flap that includes all the anterior and posterior thigh musculature after femur dissection, pedicled in the superficial femoral vessels, has been described was only once in the medical literature, and there have been no reports on a similar flap using the whole anterior and posterior musculature of the arm after humerus dissection, pedicled in the subclavian vessels, for reconstruction after interscapulothoracic amputation. Here, we describe two cases - one hemipelvectomy and one interscapulothoracicl amputation - using these two the flaps to close the defect.

This condition is usually described in patients aged greater than expected for other intraosseous osteosarcomas, and the thigh is the most common site. We report a clinical case of a 19-year-old female patient and review the literature. The patient presented with a mass in the right side of the neck and paresthesia of the upper limbs. The mass corresponded to an extraskeletal osteosarcoma. We discuss the clinical findings, image findings (conventional radiographs, computed tomography, magnetic resonance imaging, histopathology results and differential diagnosis of this condition.

    Full Text Available Objective: To evaluate the midterm clinical and radiological outcomes of the medial approach using two intervals for developmental hip dysplasia (DDH. Methods: The study involved 62 hips of 47 patients (41 girls, 6 boys treated with medial approach for DDH from 1999 to 2010. The age of the patients at surgery was 18.7 ± 2.25 months. Follow up of the patients was 11.3 ± 3.07 years. The age of the patients at the last follow up was 12.6 ± 1.74 years. According to the Tönnis classification, 13 hips were grade II, 27 hips were grade III and 22 hips were grade IV. Patients were evaluated according to Omeroglu radiological criteria and modified McKay functional criteria. The presence of avascular necrosis (AVN of the hip was questioned using the KalamchiMacEwen classification. Results: Radiologically, forty eight (77% hips were evaluated as “excellent”, 8 (13% hips as “good” and 5 (8% hips as “fair plus” and 1 (%2 hip as “fair minus”. Two (3% patients had type 1 temporary AVN and one (1% patient had type 4 AVN with coxa magna and overgrowth of the greater trochanter. According to McKay functional criteria, 56 (90% hips had “excellent” and 6 (10% had “good” results. Two (3.2% hips of one patient had to be reoperated with Salter osteotomy and femoral shortening + derotation osteotomy. Conclusion: Medial approach using two separate intervals for tenotomy and capsulotomy does not jeopardize the medial circumflex or the femoral vessels and yields satisfactory midterm results for children 18 months old with dysplasia of the hip.

    Wolbachia can profoundly influence the survival, reproduction, and defenses of insect hosts. These interactions could potentially be harnessed for managing pests or insect-transmitted diseases. Diaphorina citri Kuwayama is a phloem-feeding pest capable of transmitting the putative causal agent of citrus greening, Candidatus Liberibacter asiaticus (CLas). Like many insects, D. citri is also infected with Wolbachia (wDi). Recent studies indicate that the relative abundance of wDi could be associated with the abundance of CLas, and that wDi may contribute to regulating expression of phage lytic cycle genes in CLas, suggesting the need for better understanding of wDi biology in general. This study investigated the genetic diversity of wDi among D. citri in populations spanning eleven countries and two U.S. territories. Six Wolbachia genes, wsp, coxA, fbpA, ftsZ, gatB, and hcpA, were sequenced and compared across samples. Two prevalent wDi strains were identified across the samples, and screening of clone libraries revealed possible coinfection of wDi strains in specific populations. D. citri mitochondrial cytochrome oxidase subunit I gene (mtCOI) were more divergent between D. citri populations that were infected with different wDi strains or had different infection statuses (single infection vs. coinfection). While we could not eliminate the possibility that maternal transmission may contribute to such patterns, it is also possible that wDi may induce cytoplasmic incompatibility in their host. These findings should contribute to the understanding of wDi population ecology, which may facilitate manipulation of this endosymbiont for management of citrus greening disease worldwide. © 2017 The Authors.

    Because skeletal fractures were an important finding among persons contaminated with {sup 226}Ra, experience with fractures among dogs in the colony was summarized to determine the projected significance for persons contaminated with bone-seeking radionuclides. Comparison by Fisher's Exact Test of lifetime fracture occurrence in the skeletons of beagles injected as young adults suggested that for animals given {sup 226}Ra, {sup 228}Ra, {sup 228}Th, or {sup 239}Pu citrate, there was probably an excess over controls in fractures of the ribs, leg bones, spinous processes, and pelvis (os coxae) plus the mandible for dogs given {sup 226}Ra and the scapulae for dogs given {sup 228}Ra or 228 Th. Regression analysis indicated that significantly elevated fracture occurrence was especially notable at the higher radiation doses, at about 50 Gy average skeletal dose for {sup 239}Pu, 140 Gy for {sup 226}Ra, about 40 Gy for {sup 228}Ra, and more than 15 Gy for {sup 228}Th. The average number of fractures per dog was significantly elevated over that noted in controls for the highest radiation doses of {sup 239}Pu and {sup 226}Ra and for the higher doses of {sup 228}Ra and {sup 228}Th. For those dogs given {sup 90}Sr citrate, there was virtually no important difference from control beagles not given radionuclides, even at group mean cumulative skeletal radiation doses up to 101 Gy. Because of a large proportion of dogs with fractures that died with bone malignancy (even at dosage levels lower than those exhibiting an excess average number of fractures per dog), they conclude that fracture would not be an important endpoint at lower levels of plutonium contamination in humans such as would be expected to occur from occupational or environmental exposure.

Os animais apresentavam incoordenação, paresia de membros pélvicos, com progressão para os membros torácicos e andar com flexão da articulação metacarpo-falangeana. Na propriedade de origem dos animais, outros dois suínos apresentavam atrofia da musculatura da coxa e posição sentada quando parados. O rebanho recebia dieta não-balanceada constituída por milho, soro de leite e sobras de lavoura. Na necropsia, não foram observadas alterações significativas, mas histologicamente havia vacuolização periaxonal multifocal no tronco encefálico e na medula espinhal, quantidade discreta de esferoides axonais e macrófagos no interior dos vacúolos. A coloração com azul rápido de luxol (ARL para mielina demonstrou que as áreas de vacuolização caracterizavam focos de desmielinização. Amostras de fígado dos dois suínos apresentaram níveis de cobre muito abaixo do normal, de 13,1 partes por milhão (ppm (suíno A e 5,7ppm (suíno B.

Dois animais da espécie, obtidos post mortem por atropelamento em rodovia, foram utilizados para o estudo, obedecendo aos critérios da Lei Vigente (Lei 1.153/95. Através da dissecação, a pele foi completamente removida e os animais foram fixados em solução aquosa de formaldeído a 10%. Através de um acesso dorso-lateral, os músculos glúteo superficial, bíceps femoral e glúteo médio foram seccionados no seu local de inserção e rebatidos. Desta forma foi possível visualizar a origem e a distribuição do nervo isquiático, em ambos os antímeros dos animais. As imagens foram registradas com câmera fotográfica digital (Câmera Sony a200, 10.2mpx e os resultados foram descritos com base na Nomina Anatômica Veterinária. Os dados da origem do nervo isquiático nos dois espécimes estudados mostraram que esta ocorre a partir dos ramos ventrais de L6 e S1, podendo ter contribuição de S2. Após a sua emergência pelo forame isquiático maior, em ambos os antímeros, o nervo isquiático fornece ramos para suprir os músculos glúteo médio, glúteo profundo, glúteo superficial, gluteobíceps, bíceps da coxa, semimembranoso, semitendinoso e gastrocnêmio.

    2013-01-01

    The patterns of complexity of the male and female sexual openings in Brachyura, which have been the source of uncertainties and conflicting opinions, are documented, together with a study of the morphologies of the coxal and sternal gonopores in both sexes, penises, spermathecae, and gonopods. The vulvae, male gonopores and penises are described among selected taxa of Eubrachyura, and their function and evolution examined in the context of a wide variety of mating behaviours. The location of female and male gonopores, the condition of the penis (coxal and sternal openings and modalities of protection), and related configurations of thoracic sternites 7 and 8, which are modified by the intercalation of a wide sternal part (thoracic sternites 7 and 8) during carcinisation, show evidence of deep homology. They represent taxonomic criteria at all ranks of the family-series and may be used to test lineages. Of particular significance are the consequences of the posterior expansion of the thoracic sternum, which influences the condition, shape, and sclerotisation of the penis, and its emergence from coxal (heterotreme) to coxo-sternal, which is actually still coxal (heterotreme), in contrast to a sternal emergence (thoracotreme). The heterotreme-thoracotreme distinction results from two different trajectories of the vas deferens and its ejaculatory duct via the P5 coxa (Heterotremata) or through the thoracic sternum (Thoracotremata). Dissections of males of several families have demonstrated that this major difference not only affects the external surface (perforation of the coxa or the sternum by the ejaculatory duct) but also the internal anatomy. There is no evidence for an ejaculatory duct passing through the articular membrane between the P5 coxa and the thoracic sternum in any Brachyura, even when the sternal male gonopore is very close to the P5 coxa. Trends towards the coxo-sternal condition are exemplified by multistate characters, varying from a shallow

    Full Text Available RESUMOObjetivou-se com este trabalho comparar o padrão de crescimento, mediante ajustes das respectivas curvas de crescimento por modelos não lineares, bem como estudar o desenvolvimento de cortes de carcaça em relação ao peso da carcaça em diferentes genótipos de frangos tipo caipira. Foram utilizados 840 pintos de um dia, machos, distribuídos em delineamento inteiramente ao acaso, dos seguintes genótipos da linhagem Redbro: Caboclo, Carijó, Colorpak, Gigante Negro, Pesadão Vermelho, Pescoço Pelado e Tricolor. As aves foram alojadas em 28 boxes, sendo 30 aves/boxe, em galpão de alvenaria com acesso a um piquete de 45m², com quatro repetições. O peso corporal individual dos frangos foi medido ao nascer, aos 14, 28, 42, 56, 70 e 84 dias de idade. Para a determinação das curvas de crescimento do peso corporal das aves, os dados coletados foram avaliados por meio dos modelos não lineares: Brody, Gompertz, Logístico, Richards e von Bertalanffy. Foi empregado o PROC NLIN do SAS, utilizando-se o método interativo de Gauss-Newton. Os critérios usados para escolha do modelo de melhor ajuste da curva de crescimento foram o coeficiente de determinação, o desvio padrão assintótico, o desvio médio absoluto dos resíduos e o índice assintótico. As análises para obtenção dos coeficientes alométricos foram realizadas por meio do PROC GLM do SAS para os genótipos Carijó, Colorpak, Pesadão Vermelho, Pescoço Pelado e Tricolor. Foram avaliados os pesos da carcaça, do peito, das coxas, das sobrecoxas, das pernas e das asas das aves abatidas aos 85 dias de idade. Apenas as equações propostas por Gompertz, von Bertalanffy e Logístico atingiram a convergência, e o modelo proposto por von Bertalanffy foi o mais adequado para descrever o crescimento dos genótipos de frangos caipiras. Todos os cortes avaliados apresentaram crescimento tardio em relação ao peso da carcaça em genótipos de frangos tipo caipira.

    What makes treatment choice for developmental dysplasia of the hips diagnosed after walking age difficult is the poor understanding of prereduction conditions that obstruct the reduction in spatial terms. To evaluate these problems, we employed subtraction three-dimensional imaging to search for the factors involved in intraarticular obstruction. On the basis of the findings of preoperative subtraction three-dimensional imaging from computed tomography, we developed a new method, a minimum invasive arthroscopic reduction with limboplasty, for reduction of developmental dysplasia of the hips after walking age. The purposes of this report were to: describe the technique of the arthroscopic procedure, and evaluate our new method using radiographic parameters. Ten patients with ten hips with developmental dysplasia after walking age treated by arthroscopic reduction with limboplasty were included in this study. The mean age of the patients at reduction was 22.6 months (range, 18.6-29.7 months); mean age at follow up was 7.2 years (range, 3.9-10.9 years); and mean follow up was 5.4 years (range, 1.7-9.0 years). These ten hips were evaluated using radiographic measurements. Moderate or severe avascular necrosis of the femoral head was not observed. Two hips that had a spherical-shaped head with minimal residual height loss or coxa magna were classified as Kalamchi and MacEwen grade 1. Additional surgery had been performed for two hips classified as Severin group 4 during the course of follow up. These two hips were classified as Severin group 1 at final examination. One more hip was classified as Severin group 4 at final examination, and additional surgery was recommended. The remaining seven hips (70%) therefore obtained good evaluations by arthroscopic reduction with limboplasty alone. We developed a new reduction method by using an arthroscopic procedure for the reduction of developmental dysplasia of the hips after walking age when this dysplasia failed to be reduced

    Full Text Available A consecutive series of 21 patients with single limb atrophy (monomelic amyotrophy is reported. Sixteen had lower limb atrophy and five had upper limb involvement. The median age of the onset was 20 years. Characteristic features were sporadic occurrence, wasting confined to one limb, insidious onset with slow progression, stabilizing in 1 to 4 years, and absence of pyramidal signs. All the patients with upper limb involvement were male, however in our cases with lower limb amyotrophy there were no male preponderance. We observed wasting of the entire length of the lower limbs in six patients. There were nine cases with amyotrophy restricted to the leg and one with amyotrophy only in the thigh. In the upper limb in four cases the involvement was distal and in one patient the atrophy was proximal. The electromyographic features were suggestive of anterior horn disease not only in the affected limb but also, in some cases, in clinically uninvolved limb. Cervical or lumbar MRI was normal. MRI of the lower limb disclosed increased signal intensity in the gastrocnemius and soleus muscles in one patient suggesting denervation.Relatamos uma série consecutiva de 21 pacientes com amiotrofia de um só membro, denominada de amiotrofia monomélica. Em 16 casos a atrofia era no membro inferior e em 5 localizava-se no membro superior. Todos eram jovens e a idade média do início foi 20 anos. Os dados mais característicos da doença foram ausência de história familiar, comprometimento de um só membro, início e progressão lenta estabilizando em até 4 anos e ausência de sinais piramidais. Nossos enfermos com amiotrofia de membro superior eram todos do sexo masculino, entretanto naqueles com amiotrofia do membro inferior havia igualdade de sexos.

Foram utilizados 234 equinos sendo 136 da raça Mangalarga Marchador e 90 entre mestiços e puros Quarto de Milha utilizados em vaquejada. Foram mensuradas as medidas lineares de altura na cernelha, na garupa, no dorso, no costado e na cintura pélvica; os comprimentos de corpo, de cabeça, de pescoço, de dorsolombo, de garupa, de espádua, de braço, de antebraço, de canela anterior, de quartela anterior, de coxa, de perna, de canela posterior e de quartela posterior; os perímetros de tórax, de cintura pélvica, de canela anterior e de canela posterior; as larguras de cabeça, de peito e de garupa. O peso corporal foi estimado por meio de fita métrica (em kg. Os ângulos mensurados foram escápulo-solo, escápulo-umeral, úmero-radial, metacarpo-falangiano, pelve-solo, pelve-femoral, fêmur-tíbio-patelar, tíbio-tarso-metatarsiano e metatarso-falangiano descritos. O modelo estatístico considerou os efeitos de sexo, raça e interação sexo*raça com as médias comparadas pleo teste SNK a 5% de significância. Houve interação sexo x raça para as todas as características de alturas e larguras, para as medidas de comprimento do pescoço, do dorsolombo, garupa, espádua, braço antebraço e canela anterior e para as angulações apenas a escápulo-umeral, enquanto a raça teve efeito para todas as medidas angulares (P<0,01 exceto a úmero-radial. Os autores conluíram que os animais das raças Mangalarga Marchador e Quarto de Milha são biótipos geneticamente diferentes em suas medidas lineares e angulares e que as diferenças observadas entre as raças podem estar associadas ao tipo de andamento e à funcionalidade atribuída a cada uma delas induzidas pela seleção.

    Full Text Available PURPOSE: To evaluate the effects of fat embolism in organs such as lung and liver. METHODS: Twenty rabbits underwent autologous intramuscular fat grafting in the right thigh after liposuction. The groups were determined according to the postoperative day that occurred in euthanasia: 60, 90 and 120 day. Then, lung and liver were excised and sent to the histopathology laboratory for analysis in search of late injury secondary to a prior event of fat embolism in the tissues. RESULTS: The results showed a change in the macroscopic sample with discoloration of the liver tissue heterogeneously. There were no changes consistent with embolic effect under the microscope. CONCLUSION: The option of performing a technique of fat grafting with a less traumatic surgical procedure can be considered protective against embolic events, with no impact to late embolic events on the tissues.OBJETIVO: Avaliar a repercussão da embolia gordurosa em órgãos como pulmão e fígado.

    Full Text Available Background: The treatment of displaced intracapsular femoral neck fracture is still an unsolved problem. Non-union and avascular necrosis are the two main complications of this fracture, especially if patient presents late. Muscle pedicle bone grafting has been advocated to provide additional blood supply. We present analysis of our 32 cases of displaced femoral neck fracture treated by internal fixation and quadratus femoris based muscle pedicle bone grafting. Materials and Methods: Open reduction and internal fixation with muscle pedicle grafting was done in 32 patients. The age of patients varied from 14-62 years (average age 45 years with male to female ratio of 13:3. Twenty-nine fractures were more than three weeks old. All the cases were treated by Meyers′ procedure. The fracture was internally fixed after open reduction and then a muscle pedicle graft was applied. It was supplemented by cancellous bone graft in seven cases. Fixation was done by parallel cancellous lag screws ( n = 19, crossed Garden′s screws ( n = 7, parallel Asnis screws ( n = 5 and Moore′s pin ( n = 1.Quadratus femoris muscle pedicle graft was used in 32 cases. In the initial 12 cases the graft was fixed with circumferential proline sutures, but later, to provide a secure fixation, the graft was fixed with a cancellous screw ( n = 20. Postoperative full weight bearing was deferred to an average of 10 weeks. Results: Union was achieved in 26/29 (89.65% cases which could be followed for an average period of 3.4 years, (2-8.5 years with good functional results and had the ability to squat and sit cross-legged. Results were based on hip rating system given by Salvatti and Wilson. The results were excellent in 15 cases, good in four cases, fair in four cases and poor in six cases. Complications were avascular necrosis ( n = 2, transient foot drop ( n = 2, coxa-vara ( n = 1 and temporary loss of scrotal sensation ( n = 1. Conclusion: Muscle pedicle bone grafting with

    Full Text Available Introdução: O grande índice de lesões do ligamento cruzado anterior sem envolver contato em mulheres é motivo de curiosidade entre os cientistas, pois avaliações de aterrissagem podem sugerir a predisposição ao risco dessa lesão. Neste sentido, vários protocolos de treinamento foram utilizados como intervenção e obtiveram resultados diversificados na alteração desse fator de risco. Objetivo: O objetivo deste projeto foi avaliar as possíveis alterações de rotação do joelho na aterrissagem unipodal após a intervenção de um programa de treinamento neuromuscular. Métodos: Participaram do estudo 18 mulheres com idade entre 18 e 51 anos, que foram distribuídas em dois grupos: grupo de treinamento neuromuscular de oito semanas (GTN (n = 11 e grupo controle (GC (n = 7. Além disso, não apresentavam lesão musculoesquelética ou dores nos membros inferiores. Cada participante realizou cinco aterrissagens unipodais válidas de uma plataforma de 40 cm de altura. O processo de captura de movimento foi realizado com 12 câmeras infravermelho do sistema OptiTrack(tm para obter as coordenadas tridimensionais de marcadores fixados nos pontos anatômicos de interesse. Os sistemas de coordenadas locais da coxa e da perna foram definidos por meio dos respectivos marcadores fixados nos pontos anatômicos. Dessa forma, foram calculados os ângulos de rotação do joelho nos planos sagital, frontal e transverso através das sequências dos ângulos de Euler e as velocidades angulares através das formulações dos quatérnions. Resultados: Os resultados mostraram que houve um aumento na velocidade de rotação do joelho após o treinamento neuromuscular. Conclusão: Conclui-se que o treinamento neuromuscular resultou em maior velocidade de rotação no joelho nos 40 milissegundos que sucedem a aterrissagem unipodal.

    Full Text Available OBJETIVO: O objetivo neste estudo foi comparar a atividade mioelétrica entre o agachamento unilateral declinado e o agachamento unilateral em superfície plana, no deslocamento vertical de duas diferentes quantidades de massa. PARTICIPANTES: Um grupo de oito sujeitos treinados recreacionalmente sem sinais e sintomas de lesões nas extremidades inferiores. PROCEDIMENTOS: Em dias separados, os sujeitos realizaram dois tipos distintos de agachamento unilateral na fase descendente, diferenciados em função da direção da base de sustentação, sendo uma horizontal e outra inclinada a 25°. Os dois tipos de agachamento foram realizados com dois valores de carga, com o peso do próprio corpo e com sobrecarga representativa de 15 repetições máximas (15RM. MENSURAÇÕES: As atividades mioelétricas do reto femoral, vasto lateral, posteriores de coxa mediais (semimembranoso e semitendinoso e gastrocnêmio medial foram mensuradas nas quatro situações de teste. RESULTADOS: O grupamento muscular quadríceps mostrou-se sensível à magnitude do ângulo de inclinação da plataforma, manifestando maior atividade no agachamento declinado, e não apresentou aumentos na ativação muscular como resposta ao aumento da carga. Os músculos mediais posteriores da coxa e o gastrocnêmio medial não se mostraram sensíveis à angulação da plataforma nem ao aumento da sobrecarga. Apesar das taxas de co-contração não serem semelhantes entre as quatro situações testadas, as diferenças entre elas não se mostraram estatisticamente significativas. CONCLUSÃO: Os resultados confirmaram a maior ativação do quadríceps gerada no agachamento declinado em comparação ao agachamento realizado em superfície plana, sugerindo que esse exercício pode constituir uma alternativa para programas de reabilitação da tendinopatia patelar. Apesar de não termos encontrado diferenças estatisticamente significativas em relação à co-contração muscular, os achados

    Full Text Available O objetivo nesta pesquisa foi avaliar o potencial de crescimento, desempenho zootécnico e as características de rendimento da carcaça, das partes e dos órgãos e a qualidade da carne de três linhagens de frango de corte: Cobb (CB, Paraíso Pedrês (PP e ISA Label (IL. O delineamento foi inteiramente casualizado, com cinco repetições de 29 aves por tratamento. Semanalmente, com os dados obtidos para peso corporal médio, foi descrito o crescimento das aves, utilizando-se a equação de Gompertz e, com sua derivada, foi obtida a taxa de crescimento das aves. Três aves de cada repetição foram selecionadas e abatidas para análises do rendimento da carcaça, das partes e dos órgãos. As características físico-químicas da carne foram avaliadas utilizando-se o peito de duas destas aves. As aves CB apresentaram maior potencial de crescimento e, entre as caipiras o maior potencial foi observado para PP. Quanto ao desempenho, observou-se que a linhagem CB apresentou maior ganho de peso e consumo de ração, seguida pelas aves PP e IL. Maiores rendimentos de carcaça, de peito, sobrecoxa, fígado, intestinos e proventrículo foram obtidos com as aves CB em relação às caipiras, que não diferiram entre si. As aves CB apresentaram carne de peito com maior pH e maior capacidade de retenção de água que as de linhagens caipiras, que apresentaram carne de peito menos macia e com maior intensidade da cor vermelha. Maior potencial de crescimento e maiores rendimentos de pés, coxa, coxa+sobrecoxa e de coração foram verificados nos machos, enquanto, nas fêmeas, maiores rendimentos de peito, porcentagem de gordura abdominal, fígado, moela e proventrículo. As aves CB em relação às caipiras possuíram maior potencial de crescimento e maior rendimento de partes nobres, mas as caipiras apresentaram atributos diferenciados que justificam sua criação.This is study aimed to compare growth performance, meat quality, and carcass yield of three

As fases de crescimento avaliadas foram: fase 1, 1 - 21dias de idade e fase 2, 22 - 42 dias de idade. O delineamento experimental foi inteiramente casualizado, sendo os tratamentos constituídos de cincos planos nutricionais (PN, com seis repetições de 25 aves cada. Os planos nutricionais são: PN1 - ração basal (21,4% PB - fase 1 + ração basal (19,3% PB - fase 2; PN2 - ração a basal (fase 1 + ração com 18% PB (fase 2; PN3 - ração basal (fase 1 + ração com 16% PB (fase 2; PN4 - ração com 19% PB (fase 1 + ração com 16% PB (fase 2; e PN5 = ração com 17 % PB (fase 1 + ração com 16% PB (fase 2. Exceto para a ração basal, reduziu-se o nível de Pd para 0,34 e 0,30% e o de Ca para 0,80 e 0,70% nas fases 1 e 2, respectivamente; nestas rações foram adicionados 500 FTU de fitase/kg de ração. As aves alimentadas com PN2 e PN3 apresentaram desempenho semelhante ao daquelas que receberam PN1, enquanto o das aves que receberam os PN4 e PN5 permaneceu inalterado. Os rendimentos de carcaça e peito não foram influenciados pelos planos nutricionais. As aves que consumiram a ração basal nas duas fases de criação (PN1 apresentaram maior rendimento de coxa+sobre-coxa. Houve aumento da gordura abdominal quando as aves receberam os PN3, 4 e 5. É possível reduzir a PB da ração até 16% na fase 2, suplementada com fitase e aminoácidos, desde que a ração da primeira fase seja formulada com níveis nutricionais recomendados.This study was carried out to evaluate the performance and characteristics of carcass of broiler chickens fed diets with reduced levels of CP, available P (aP and Ca, supplemented with phytase and amino acids.

O resíduo de tomate aumentou o consumo de ração nos períodos de 1 a 7, 8 a 14 e 29 a 36 dias de idade, mas piorou o ganho de peso e a conversão alimentar dos frangos de corte até 29 dias de idade. Os pesos de carcaças (g e das partes nobres, peito, coxa e sobrecoxas diminuíram linearmente como consequência do resíduo no peso das aves nas fases pré-inicial e inicial, ou seja, até 28 dias de idade. Os rendimentos (% dessescortes não foram afetados pelo uso de resíduo de tomate, exceto os rendimentos de coração e fígado. O uso de resíduo de tomate em rações para frangos de corte durante o período de 1 a 28 dias pode diminuir o ganho de peso e piorar a conversão alimentar. O resíduo de tomate pode ser utilizado em níveis de até 20% em rações para frangos de corte no período de 29 a 42 dias de idade, pois nesse nível não prejudica o ganho de peso nem a conversão alimentar das aves.

Dentre os estudos analisados, perímetro da cintura e diâmetro abdominal sagital apresentaram melhor capacidade preditiva para RI, com resultados mais consistentes. As relações cintura/coxa, cintura/estatura, pescoço/coxa, o índice de conicidade e o índice sagital demonstraram resultados positivos, contudo mais estudos são necessários para consolidá-los como preditores de RI. Os resultados obtidos com o uso do índice de massa corporal e da relação cintura/quadril foram mais inconsistentes. Sugere-se a realização de estudos avaliando o desempenho desses indicadores em predizer RI na população brasileira, pois resultados de estudos feitos com outras populações muitas vezes não são aplicáveis à nossa, devido às diferenças étnicas resultantes da grande miscigenação no País.Algunos estudios han analizado la eficiencia de indicadores antropométricos para predecir resistencia a la insulina (RI, por ser más económicos y accesibles.

Os estágios de maturação genital de Tanner (G-5 foram utilizados para subdividir a amostra nas três categorias sugeridas por Nicoletti: pré-puberal (G1, puberal inicial (G2-3 e puberal avançada (G4-5. Foi utilizada a análise discriminante passo a passa (stepwise, tendo como critério de seleção o aumento da porcentagem de indivíduos classificados corretamente. Foram utilizadas 35 variáveis, das quais foram selecionadas: estatura, dobras cutâneas tríceps e subescapular, perímetros da perna e do braço relaxado, massa corporal, e os comprimentos do antebraço e coxa. Essa análise gerou um novo grupo composto por 87% do grupo original. Duas funções lineares discriminantes (LDF1 e LDF2 emergiram: LDF1 diferenciou os indivíduos pré-púberes dos púberes avançados, tendo incluído as variáveis: estatura, massa corporal, comprimento do antebraço e coxa, e os perímetros do braço e da perna. A segunda função, a LDF2, diferenciou os indivíduos no início da puberdade dos demais grupos. O segundo grupo de variáveis incluiu: a dobra cutânea do tríceps e o perímetro da perna. Os intervalos de confiança demonstraram que duas variáveis de tamanho, duas de gordura subcutânea, duas de robustez esquelética e duas de muscularidade relativa são suficientes para guiar os técnicos, na classificação de jovens nadadores, em categorias que melhor aproximem do seu estágio maturacional. Somente as dobras cutâneas do tríceps e subescapular mostraram superposição dos intervalos de confiança nas três categorias.

    To design and produce a lesser trochanteric reduction fixation system and verify its value and effectiveness. A lesser trochanteric reduction fixation system was designed and produced according to the anatomical features of the lesser trochanteric fractures. Sixty-six patients with intertrochanteric fractures of Evans type III were included between January 2010 and July 2012. Of 66 patients, 32 were treated with dynamic hip screw (DHS) assisted with the lesser trochanteric reduction fixation system (study group), and 34 cases were treated with DHS only (control group). The 2 groups were comparable with no significant difference in gender, age, the reasons, and the types of the fractures (P > 0.05). The operation time, intraoperative blood loss, neck-shaft angle, bone healing time, ratio of successful fixations, and the functional evaluation of the hip joint after operation were compared between 2 groups. The study group had shorter operation time [(58.4 ± 5.3) minutes] and less intraoperative blood loss [(186.3 ± 6.6) mL than the control group [(78.5 ± 6.2)minutes and (246.2 ± 8.7) mL], showing significant differences (t = -14.040, P = 0.000; t = -31.145, P = 0.000). There was no significant difference in neck-shaft angle between study group [(138.6 ± 3.0)] and control group [(139.4 ± 2.9) degrees] (t = -1.044, P = 0.301).

    Full Text Available No Brasil, tanto a criação quanto a comercialização da carne de pato (Cairina moschata ainda é incipiente, mas devido a sua rusticidade, fácil manejo, e carne apreciada no mercado, entende-se que a obtenção de produtos à base de carne de pato apresenta-se como uma alternativa rentável na indústria de alimentos. O uso de culturas iniciadoras na elaboração de produtos fermentados é uma prática comum na indústria de produtos cárneos estando diretamente relacionada às características de flavor, textura, cor e vida-de-prateleira do produto final. Avaliou-se o uso de culturas iniciadoras na elaboração de embutido fermentado à base de carne de pato obtida da desossa manual da coxa e sobrecoxa. Uma mistura de culturas iniciadoras de Lactobacillus plantarum BN e Kokuria varians CCT 4492 foi usada para inocular a massa cárnea. Os embutidos foram defumados em câmara para defumação a 23±1°C por aproximadamente 19 horas e curados por 25 dias. A contagem inicial de células viáveis na massa do embutido foi de 6,08Log10UFC/g e de 6,04Log10UFC/g para bactérias ácido-lácticas e Micrococcacea, respectivamente. Após o segundo dia do processo, bactérias ácido-lácticas apresentaram um crescimento de 0,79 ciclos logarítmicos e no décimo primeiro dia um aumento de 2,58 ciclos logarítmicos. O valor médio de acidez, em ácido láctico, no produto final foi de 0,39% e o valor de pH de 5,11. As análises físico-químicas apresentaram-se dentro dos padrões da legislação brasileira. O produto elaborado apresentou perfil sensorial dentro dos padrões aceitáveis de qualidade.In Brazil, duck raising (Cairina moschata and duck meat commercialization are still incipient activities, but due to this animal's rusticity, easiness of management and the marketability of its meat, they may be seen as profitable alternatives in the food industry.

O somatotipo foi calculado de acordo com o método antropométrico de Heath-Carter. A composicão corporal segundo a tática de fracionamento de massas de Kerr e foi analisada a proporcionalidade através da estratégia Phantom de Ross. Os procedimentos antropométricos usados foram os recomendados pela ISAK. Na composição corporal foi estimada uma massa muscular de 54% e uma massa de gordura de 17,5%. Os resultados indicam que os ginastas argentinos possuem um biotipo de características similares ao resto dos ginastas de nível internacional. Porém, costumam ser mais baixos, com maior peso corporal e com os perímetros de tórax, cintura, coxa e panturrilha mais elevados. Isto nos tenderia a supor que estes ginastas têm uma desvantagem biomecânica que prejudica a performance nos eventos de ginástica artística desportiva.

    Full Text Available CONTEXTUALIZAÇÃO: A fratura distal do fêmur é uma das possíveis complicações no período pós-operatório de reconstrução de LCA, porém, de incidência rara. RELATO DE CASO: Descreve-se o caso de um atleta de 34 anos, gênero masculino, no quinto mês de pós-operatório de reconstrução de LCA. O caso evoluía normalmente de acordo com o protocolo estabelecido; o paciente apresentava bom controle e estabilidade sensoriomotora, quando sofreu fratura supracondiliana do fêmur ao realizar um salto durante atendimento fisioterápico. A reconstrução ligamentar foi realizada com enxerto dos músculos flexores do joelho e a fratura, ocasionada posteriormente, reduzida e fixada com placa e parafuso. Dez meses após a redução aberta e fixação interna da fratura, apresenta função regular na escala Lysholm, amplitude de movimento normal e força muscular grau V em flexores e extensores da coxa. DISCUSSÃO: Poucos relatos de caso semelhantes ao presente foram encontrados na literatura; a maioria apresentou fratura do fêmur após a reconstrução do LCA com tendão patelar. Este caso mostra-se relevante pela associação da fratura supracondiliana do fêmur com reconstrução ligamentar com tendões dos flexores, visto que apenas um trabalho seguiu tal direção. Dentre as prováveis causas dessa fratura, destacam-se uma fragilidade óssea por desuso e túnel ósseo femoral de diâmetro maior que o padrão, apesar de não haver consenso em relação a essas alterações. Uma hipótese sugerida pelos autores deste relato é de que o túnel ósseo de fixação do enxerto pode ter sido um intensificador de estresse sobre o local da fratura.BACKGROUND: Distal femoral fracture is one of the possible complications on the post operative period of the ACL reconstruction; however, with rare incidence. CASE REPORT: This study reports a male 34 year-old athlete, five months after ACL reconstruction surgery. The case developed normally in accordance

    Full Text Available OBJETIVO: Relatar o caso de um paciente com displasia tanatofórica, uma forma autossômica dominante e letal de nanismo, diagnosticado ainda no período pré-natal, e revisar a literatura, discutindo os principais diagnósticos diferenciais e ressaltando a importância do ultrassom fetal na identificação de fetos portadores dessa displasia. DESCRIÇÃO DO CASO: O paciente é o segundo filho de pais jovens sem história familiar de doenças genéticas. O ultrassom fetal realizado com 35 semanas de gestação mostrou polidrâmnio, proeminência frontal e desproporção entre crânio e tronco, com hipoplasia torácica e encurtamento dos ossos longos, compatível com o diagnóstico de displasia tanatofórica. Ao nascimento, a criança era pequena e possuía hipotonia, macrocefalia, fontanelas amplas, hipoplasia de face média, olhos protrusos, hemangioma plano no nariz e pálpebras, nariz em sela, micrognatia, pescoço e tórax curtos e encurtamento importante de braços, antebraços, coxas e pernas. A avaliação radiográfica mostrou crânio com grande diâmetro transverso, tórax com costelas curtas e corpos vertebrais reduzidos, importante encurtamento e deformidade dos ossos longos dos membros superiores e inferiores (os fêmures eram curvos e hipoplasia da bacia. Esses achados confirmaram o diagnóstico pré-natal de displasia tanatofórica. O paciente evoluiu para o óbito poucos dias após o nascimento devido à insuficiência respiratória. COMENTÁRIOS: A ultrassonografia fetal é um método não invasivo capaz de diagnosticar inúmeras displasias ósseas, incluindo a tanatofórica. A importância do diagnóstico intra-útero reside no fato de que auxilia no diagnóstico diferencial, e permite o aconselhamento genético à família.OBJECTIVE: To report a patient with thanatophoric dysplasia, an autosomal dominant and lethal form of nanism diagnosed in the prenatal period and to review the literature, discussing the main differential

    Full Text Available The epithelioid sarcoma (ES is an unusual variant of the sarcoma, not reaching 1% of all soft tissue sarcomas. Initially reported in 1970, it has a more aggressive variant, which was classified as the “proximal-type” in 1997. These are aggressive tumors with high rates of distant metastasis and local relapses. Isolated radio and chemotherapy responses are poor and free-margin surgical resection is the treatment of choice.This is the case report of a 25-year-old male patient diagnosed with “proximal-type” ES in the perineal region. He underwent surgical resection in another institution and was later admitted to our institution with local recurrence with rectal and left thigh muscle invasion. Neoadjuvant radio-chemotherapy was performed, followed by laparoscopic abdominoperineal rectal resection and partial left hemipelvectomy associated with left lower-limb amputation. The patient had no postoperative complications and is currently undergoing outpatient follow-up. The anatomopathological analysis showed tumor-free margins.The “proximal-type” ES is a rare soft-tissue sarcoma subtype. High local recurrence, as well as the metastasis rates, makes its treatment a challenging task. Resumo: O sarcoma epitelióide (SE é um subtipo incomum de sarcoma, não chegando a 1% dos sarcomas de partes moles. Foi inicialmente descrito em 1970, sendo que em 1997 uma variante mais agressiva foi classificada como “tipo proximal”. São tumores agressivos, com altas taxas de metástases e recidiva local, com resposta pobre à quimioterapia e radioterapia isoladas. A ressecção cirúrgica com margens livres é o tratamento padrão.Apresentamos o caso de um paciente de 25 anos com SE tipo proximal avançado em região perineal, submetido a ressecção em outro serviço, evoluindo com recidiva local com invasão do canal anal e musculatura da coxa esquerda. Foi realizado tratamento radioquimioterápico neoadjuvante seguido de ressecção cirúrgica com

    Full Text Available OBJETIVO: Realizar o estudo anatômico, em cadáveres, do retalho corticoperiosteal do côndilo femoral medial baseado na artéria genicular medial, avaliando a dificuldade de dissecção e padrões topográficos. MÉTODOS: Foram estudados 15 membros de oito cadáveres, com idade variando de 19 a 74 anos. Dispostos em posição supina, foi realizada incisão longitudinal na face medial do terço distal da coxa, exposição dos vasos geniculares descendentes entre os músculos vasto medial e sartório. Foram analisados a distância entre a origem da artéria genicular descendente e a interlinha medial do joelho, o diâmetro do vaso, o comprimento do pedículo, a presença do ramo fasciocutâneo e sua localização. RESULTADOS: A distância entre a origem da artéria genicular descendente e a interlinha medial do joelho variou de 11,2cm a 14,5cm, com média de 12,63cm. O diâmetro médio da artéria foi de 2,5mm (de 2,25mm a 2,75mm. A distância entre a origem da artéria genicular descendente e o ramo fasciocutâneo variou entre 1,0 e 1,5cm.

Assim constituiu-se como objetivo do presente estudo a observação das lesões desportivas (LD em atletas da elite brasileira do atletismo, associando-as aos seus mecanismos de instalação e características da modalidade. Foram entrevistados 86 atletas (47 homens e 39 mulheres convocados para representar o Brasil durante o ano de 2003. Utilizou-se um inquérito de morbidade referida, validado anteriormente, para obtenção dos dados referentes aos atletas e suas lesões. Para a análise dos resultados adotou-se o teste de Goodman para contrastes entre e dentro de proporções binomiais, sendo todas as conclusões discutidas para 5% de significância estatística. Os resultados mostraram que há maior taxa de lesão por atleta (l/a, nas provas combinadas (3,5 l/a, seguidas por eventos de velocidade (2,6 l/a, resistência (1,9 l/a e saltos (1,9 l/a respectivamente. O principal mecanismo causal é a alta intensidade acometendo preferencialmente velocistas e fundistas. Outra forte associação foi observada entre lesões musculares e provas de velocidade, que também apresentam preferência para ocorrência de lesão na região da coxa. As atividades com elevada intensidade foram o principal responsável por lesões musculares, enquanto as osteoarticulares e tendinopatias ocorrem com excesso de repetições. Concluiu-se, a partir dos achados, que existem associações entre lesões e fatores causais, como entre provas e lesões, mecanismos de lesão e local anatômico.Los procesos de cuantificación y de asociación de las lesiones del deporte y sus posibles factores causales son importantes para un mejor entendimiento sobre el asunto.

Os experimentos foram conduzidos no período de 3 a 6 semanas de idade das aves. Em ambos os experimentos, os quatros níveis de PB foram: 20,8; 19,7; 18,6 e 17,5% PB. No experimento 2, também foram testados outros dois tratamentos com rações contendo 20,8 e 17,5% de PB e alta digestibilidade (ADig, à base de milho, farelo de soja, amido de milho e proteína isolada de soja. Nos dois experimentos, o consumo de ração não foi afetado pela redução de PB. No experimento 1, o ganho de peso (GP, a conversão alimentar (CA e os rendimentos de peito e de coxa foram afetados negativamente pela redução dos níveis de PB, enquanto, no experimento 2 estas variáveis não foram influenciadas. No entanto, em ambos os experimentos, na semana de 21 a 28 dias, o GP e a CA foram influenciados negativamente pela redução dos níveis de PB na ração. Com o decréscimo no nível de PB, a digestibilidade da matéria seca (MS e da matéria orgânica (MO aumentou no experimento 2, em virtude da menor inclusão de farelo de soja. Em ambos os experimentos, a retenção relativa de proteína foi superior para rações com baixos níveis de PB. No experimento 2, apesar de os níveis de PB não terem influenciado o desempenho, a ração de ADig proporcionou maior digestibilidade da MO e tendência à maior digestibilidade da MS. As rações com 17,5% PB e ADig promoveram balanço mais positivo e maior retenção relativa de proteína em comparação às de digestibilidade padrão. Considerando todos os resultados, a formulação de rações com AAD mostrou vantagens em relação aos AAT.Two experiments (Exp were carried out to evaluate diets for broilers formulated with

    Full Text Available O experimento foi realizado para avaliar o efeito da redução do nível de proteína bruta (PB da ração formulada de acordo com o conceito de proteína ideal e suplementada com aminoácidos industriais, sobre o desempenho e rendimento de cortes de frangos de corte machos de 22 a 42 dias de idade mantidos em ambiente termoneutro. Foram utilizados 280 frangos de corte machos "Cobb" com peso inicial de 856 ± 6,48 g, distribuídos em delineamento experimental inteiramente casualizado, com cinco tratamentos (21,6; 20,6; 19,6; 18,6 e 17,6% de PB, oito repetições de sete aves por unidade experimental. A temperatura no interior da sala foi mantida em 21,6 ± 0,7ºC, a umidade relativa em 74 ± 4,0% e a temperatura de globo negro em 22,5 ± 0,7ºC. O índice de temperatura de globo e umidade (ITGU calculado para o período foi de 70 ± 0,9. Não houve efeito da redução dos níveis de PB sobre o ganho de peso e o consumo de ração, entretanto, a conversão alimentar foi influenciada pela redução dos níveis de PB sendo que as aves alimentadas com a ração que continha 22,0% de PB apresentaram o melhor resultado. A redução dos níveis de PB não influenciou o peso absoluto de carcaça e os pesos absoluto e relativo de peito, coxa e sobrecoxa. A redução do nível de PB da ração, de 21,6 para 17,6%, e formulada de acordo com o conceito de proteína ideal piora a conversão alimentar dos frangos de corte mantidos em ambiente termoneutro, não influenciando as demais variáveis estudadas.The objective of this experiment was to evaluate the effects of dietary crude protein (CP level reduction of ration formulated according to ideal protein concept and with supplementation of industrial amino acids on the performance and yield of noble cuts of broilers from 22 to 42 days of age kept under thermoneutral conditions. It was used 280 "Cobb" male broilers with initial weight of 856 ± 6.48 g, distributed in a completely randomized experimental

    Full Text Available A flexibilidade consiste na capacidade motora relacionada com a amplitude de movimento atingida por cada articulação. A flexibilidade sofre decréscimo com a idade; durante a adolescência, devido ao estirão de crescimento puberal, ocorre considerável perda dessa característica. Sabe-se, também, que atletas de futebol e futsal, como resultado dos programas de fortalecimento visando o gesto do chute, tendem a apresentar considerável encurtamento da musculatura posterior da coxa, o que promove perda de rendimento e predispõe o atleta a lesões musculares. Assim, o objetivo do presente estudo foi verificar o efeito sobre a flexibilidade proporcionado por um programa de Pilates® em uma equipe de futsal da categoria juvenil (17-20 anos, considerada uma população altamente propensa a limitações dessa capacidade e que pode usufruir de inúmeros benefícios com o incremento da mesma. Para tal, dividiu-se o grupo de atletas em grupo Pilates (GP, n = 6 e grupo controle (GC, n = 5. Optou-se por avaliar a flexibilidade dos atletas com dois métodos (flexímetro e banco de Wells. Realizaram-se avaliações em três momentos distintos: pré (24 horas antes do início do programa, pós-imediato (24 horas após o fim do programa e pós-tardio (15 dias após o fim do programa. O programa foi realizado em três sessões semanais de aproximadamente 25 minutos, durante quatro semanas. Os resultados obtidos com o presente estudo comprovam que o protocolo de treinamento com o método Pilates® empregado pelos pesquisadores conseguiu incrementar a flexibilidade dos atletas juvenis de futsal. Tal programa apresentou efeitos agudos, representados pelo aumento estatisticamente significante da flexibilidade no pós-imediato (p 0,05 no período pós-tardio para ambos os métodos. Sugere-se que mais estudos sejam realizados com o método Pilates® a fim de elucidar todas as possibilidades de aplicação dessa modalidade terapêutica.The flexibility consists in

    Full Text Available O culturismo é um esporte que enfatiza a aparência física, a configuração e o formato corporais, buscando assim a excelência estética. A cineantropometria é uma ferramenta fundamental para guiar o curso do treinamento no culturismo. No entanto, existe escassez na produção de trabalhos científicos para essa população. O objetivo deste trabalho é descrever a composição corporal, o somatotipo e a proporcionalidade de 23 culturistas finalistas do Campeonato Brasileiro de Culturismo do ano de 2000. Os atletas foram avaliados momentos antes da competição e as seguintes variáveis determinadas: peso total, estatura, nove dobras cutâneas (triceptal, subescapular, biceptal, peitoral, axilar média, supra-ilíaca, abdominal, medial da coxa e medial da perna, dois perímetros musculares (braço fletido e perna e três diâmetros ósseos (umeral, biestiloidal e femoral, conforme a metodologia proposta pela International Society for the Advancement of Kineanthropometry (ISAK. Os atletas apresentaram idades entre 20 e 56 anos e peso corporal entre 57,4kg e 105,8kg. O somatório das nove dobras cutâneas (S9DC variou entre 38,4mm e 70,2mm. O somatotipo encontrado foi de 1,8-8,1-0,7, classificado como mesomorfo balanceado. O percentual médio de gordura foi de 9,65%, usando o protocolo de Faulkner, proposto pelo Grupo Brasileiro de Cineantropometria. O peso de gordura encontrado foi de 7,29kg. Quando comparados ao Phantom, os atletas estudados apresentaram maiores: peso corporal (Z = +1,66, perímetro de braço (Z = +5,26 e perímetro de perna (Z = +1,91. Conclui-se que os culturistas brasileiros de elite estudados apresentam baixo percentual de gordura e grande peso muscular, quando comparados com o modelo de Ross e Wilson (1974, sendo a sua estrutura corporal semelhante à dos culturistas da elite internacional.El fisicoculturismo es un deporte que enfatiza la apariencia física, la configuración y el formato corporal, buscando así la

    Full Text Available Um experimento foi conduzido com o objetivo de avaliar o efeito de relações crescentes entre treonina (Thr e lisina (Lys digestível em dietas de frangos de corte nas repostas produtivas dos 15 aos 37 dias de idade. Os aumentos dos níveis de treonina das dietas foram obtidos a partir de inclusões crescentes de farelo de soja (FS ou L-treonina (L-Thr. Foram alojados 1.200 frangos de corte machos Ross x Ross 308 em arranjo fatorial com três relações entre Thr e Lys (63,5, 66,0 e 68,5% e as duas fontes de Thr supracitadas. Cada um dos seis tratamentos foi constituído por oito repetições de 25 aves. As dietas foram formuladas para garantir o nível mínimo de exigência para os demais nutrientes e energia. Não houve efeito do nível de treonina sobre respostas de desempenho zootécnico, consumo de água, matéria seca da cama, lesões de pododermatite e rendimento de carcaça e cortes. Também não foi observado efeito da fonte de Thr sobre peso corporal, consumo de dieta, matéria seca da cama, lesões de pododermatite, rendimentos de carcaça, filé de peito, coxas e sobrecoxas. Entretanto, a conversão alimentar foi melhor (P=0,009 e o consumo de água maior (P=0,011 quando o aumento em Thr foi originado do FS, enquanto o rendimento de peito foi superior (P=0,035 para as dietas suplementadas com L-Thr. Foi possível identificar uma resposta diferenciada entre fonte e nível de Thr para ganho de peso e CA, demonstrando que, quando a relação entre Thr e Lys foi de 68,5%, existiu uma evidente melhora para as aves recebendo este nível de Thr a partir do FS. As quantidades de aminoácidos (AA essenciais a partir do quarto AA limitante foram superiores para as dietas com níveis crescentes de FS. Supõe-se que as diferenças obtidas entre as respostas das aves recebendo dietas com o aumento em Thr a partir de L-Thr ou FS tenham sido devidas a desiguais quantidades ou balanceamento de AA essenciais consumidos a partir do quarto AA

    diferentes condições de ensaio sobre a atividade da GSH-Px em coxas de frangos, oriundos de diferentes dietas, nas quais se variaram a fonte e a concentração de selênio. As atividades da GSH-Px foram determinadas seis horas após o abate e 120 dias após o armazenamento a -18 ºC. As diferentes condições de ensaio envolveram a pré-incubação (0, 10 e 30 minutos, o meio de reação, os tipos de substratos [H2O2 (0,72 mM, 7,2 mM e 72 mM e terc-butil hidroperóxido 15 mM] e as concentrações diferentes de tampões [tampão 1 (fosfato de potássio 50 mM pH 7,0 + EDTA 1 mM + mercaptoetanol 1 mM e tampão 2 (tris-HCl 50 mM pH 7,6 + EDTA 1 mM + mercaptoetanol 5 mM] no meio de reação. Os resultados mostraram que: i a maior atividade da GSH-Px foi observada quando a enzima e o substrato foram colocados em contato a 22 ºC sem qualquer pré-incubação; ii o peróxido de hidrogênio, quando utilizado em concentrações acima de 0,72 mM, saturou a enzima GSH-Px e inibiu sua atividade; iii a enzima GSH-Px apresentou maior afinidade para o substrato peróxido de hidrogênio, quando comparado ao peróxido de terc-butil, e iv a adição do tampão mercaptoetanol não promoveu aumento na atividade da enzima GSH-Px. A atividade da GSH-Px também não foi influenciada pela fonte e pela concentração de selênio vindo pela dieta. Os resultados obtidos permitiram definir qual a melhor temperatura de contato entre a enzima e o substrato (22 ºC e qual a melhor concentração e o tipo de substrato e de tampão a serem utilizados. Essas informações poderão servir de base para a execução de futuros trabalhos envolvendo a determinação da atividade da GSH-Px em carnes, pois há contradições nas poucas informações existentes na literatura.

    Full Text Available The most frequent adverse reactions to nonsteroidal anti-inflammatory drugs are upper and lower gastrointestinal tract disorders, hepatotoxicity, nephrotoxicity, a decrease in the synthesis of proteoglycans of the cartilaginous tissue and allergic reactions. In our previous studies we have found out that Ukrainian vinboron, the antispasmodic with polytrophic pharmacological effects, can improve the safety profile of the popular non-steroidal antiphlogistics ibuprofen and can also potentiate its anti-inflammatory effect. That fact has become the background to a detailed study of the therapeutic action mechanisms of these drugs when they are used together.Aim of the study. To characterize the influence of vinboron (11 mg/kg, i.g. on the anti-inflammatory activity of ibuprofen (218 mg/kg, i.g. when combined, in a model of experimental rheumatoid arthritis according to pathomorphological, morphometric and cone-ray computerized tomography of rats’ hind limbs.Materials and methods. To reproduce the conditions for the administration of ibuprofen corresponding to its clinical use, we selected a model of experimental rheumatoid arthritis-adjuvant arthritis (AA in rats. On the 28th  day the animals were excluded from the experiment. It was followed by the amputation of the hind limbs at the level of the hocks (art. coxae and fixation of the material in 10.0% aqueous solution of neutral formalin. The ankle joints were decalcified. The drugs were prepared according to the standard procedure. Microscopy and photographing of histological preparations were carried out with the light microscope OLIMPUS BX 41 at magnifications of 40, 100, 200 and 400 times. The obtained images were processed and morphometry was carried out with the program “Quick PHOTO MICRO 2.3”.

MÉTODOS: Realizou-se um estudo do tipo corte transversal envolvendo 78 gestações únicas de fetos vivos, euploides e sem malformações estruturais, dentro de 48 horas antes do nascimento. O VolBra e o VolCox foram aferidos por meio da ultrassonografia tridimensional utilizando-se o modo multiplanar a intervalos de 5 mm. A CA e o CF foram aferidos por meio da ultrassonografia bidimensional. Foram realizadas análises de regressão linear e polinomial para determinação da melhor fórmula para predizer o peso fetal com base no VolBra, VolCox, CA e CF. Os erros obtidos com essas fórmulas foram comparados com os obtidos com as fórmulas de Shepard e Hadlock por meio de ANOVA. RESULTADOS: A melhor fórmula que estimou o peso ao nascimento foi uma linear simples (Peso= -1486,1 + 60,5CA + 140,57CF + 16,6VolBra + 4,8VolCox, com R2= 0,932.

    Full Text Available Dois ensaios foram conduzidos para se avaliarem os efeitos de níveis de lisina digestível em rações, mantendo ou não a relação aminoacídica, sobre o desempenho de frangos de corte dos 22 aos 42 dias, criados em ambiente de termomeutralidade. No ensaio 1, foram utilizados 210 frangos de corte machos Avian Farms com peso inicial médio de 662,5 g e, no ensaio 2, 168 frangos com peso inicial médio de 623,7 g. Em ambos os ensaios, o delineamento experimental foi o inteiramente casualizado; no ensaio 1, as aves foram distribuídas em cinco tratamentos (níveis de lisina digestível em rações convencionais e seis repetições, com sete aves cada e, no ensaio 2, em quatro tratamentos (níveis de lisina em rações mantendo a relação aminoacídica e seis repetições, com sete aves cada. Nos ensaios 1 e 2, os níveis de lisina digestível da ração influenciaram de forma linear crescente o ganho de peso e a conversão alimentar. No ensaio 1, observou-se efeito linear crescente dos tratamentos sobre o peso absoluto da carcaça. Não foi observado efeito dos tratamentos sobre o peso relativo da carcaça e os pesos absoluto e relativo de cortes nobres e de gordura abdominal. No ensaio 2, os pesos absoluto e relativo do peito e da coxa aumentaram linearmente, enquanto o peso absoluto da sobrecoxa elevou de forma quadrática até o nível de 0,955% de lisina. O peso relativo da sobrecoxa e os pesos absoluto e relativo da gordura abdominal não foram influenciados pelos tratamentos. Concluiu-se que frangos de corte machos Avian Farms na fase de 22 a 42 dias de idade, mantidos em ambiente de termomeutralidade, exigem no mínimo 1,015 e 1,075% de lisina digestível na ração convencional e na ração mantendo a relação aminoacídica, respectivamente, correspondente a um consumo estimado de 28 g de lisina digestível.Two trials were conducted to evaluate the effects of increasing dietary digestible lysine levels, maintaining or not the amino

No primeiro ensaio, utilizaram-se 900 aves com peso médio inicial de 957,4 g distribuídas em parcelas experimentais de 30 aves e três repetições e, no segundo ensaio, 180 frangos com peso médio inicial de 866,22 g, divididos em parcelas de três aves e seis repetições. As características avaliadas foram desempenho, rendimento de cortes e composição corporal (1º ensaio, balanço de nitrogênio e digestibilidade aparente das dietas (2º ensaio. Houve interação entre os níveis de lisina e zinco para o ganho de peso, a conversão alimentar, a matéria seca ingerida e o balanço energético. Os rendimentos de peito, coxa e sobrecoxa tiveram aumentos lineares em resposta ao acréscimo no nível de lisina digestível na dieta. O melhor desempenho foi obtido com o nível de 0,997% de lisina digestível (ou 1,134% lisina total e de 43 ppm de zinco. Para maior rendimento dos cortes, o nível de lisina digestível recomendável deve ser no mínimo 1,002% (ou 1,139% de lisina total, independentemente dos níveis de zinco quelato. A maior inclusão de zinco em dietas para frangos de corte dos 22 aos 42 dias de idade não melhora a utilização da lisina na dieta e aumenta a deposição de gordura corporal.The dietary effects of digestible lysine and chelate zinc for male broiler chickens from 22 to 42 days of age were evaluated in two experimental assays.

    Full Text Available JUSTIFICATIVA E OBJETIVOS: O clássico bloqueio "3 em 1" por via anterior tem suscitado divergências quanto ao envolvimento anestésico de seus três nervos participantes, o femoral, o cutâneo lateral da coxa e o obturador. O objetivo deste estudo é verificar o desfecho do bloqueio "3 em 1" por via anterior, através das técnicas: injeção única (G1, cateteres curtos (G2 e cateteres longos (G3. Os bloqueios "3 em 1", clinicamente identificados como completos ou superdimensionados foram, adicionalmente, investigados por meio de rádio imagem. MÉTODO: A identificação do espaço subfascial ilíaco nos bloqueios "3 em 1" com injeção única ou com cateteres foi feita pela perda de resistência ao ar. Em vários eventos dolorosos, o volume anestésico administrado variou entre 30 e 40 ml e a introdução cranial dos cateteres foi até 18 cm no espaço subfascial ilíaco. Quando a pesquisa clínica apontava envolvimento do nervo obturador ou de outro nervo adicional ao bloqueio "3 em 1", complementava-se a investigação com estudo radiográfico e tomodensiométrico com o propósito de estabelecer correspondência com a anatomia pélvica. RESULTADOS: O envolvimento dos nervos fêmoro cutâneo lateral e obturador não foram constantes, ao contrário do nervo femoral. No estudo, nenhum bloqueio "3 em 1" completo com injeção única (G1 se manifestou, e sim um bloqueio "2 em 1", com a participação eventual do ramo femoral do nervo genitofemoral (bloqueio "2,5 em 1". Contudo, quando foram utilizados cateteres curtos (G2, obteve-se bloqueio "3 em 1" em apenas um paciente, ao passo que com cateteres longos (G3 introduzidos no sentido cefálico até 18 cm no espaço subfascial ilíaco, três bloqueios "3 em 1" superdimensionados foram registrados, pelo envolvimento adicional dos nervos fibular comum em dois pacientes e o nervo tibial em um paciente. CONCLUSÕES: Apesar da pequena amostra, com injeção única (G1, sempre se obteve um bloqueio "2
