A case study of partial agenesis of the corpus callosum: Audiological implications

This case study represents four years of audiological observations, testing and aural habilitation of a female child with a partial agenesis of the corpus callosum (ACC). The ACC was diagnosed by MRI scans to eliminate neurological causes for developmental delay at six months of age. This child was also born with a cleft palate and was diagnosed with Robinow Syndrome at 3 years and 3 months of age. The audiological results showed an improvement in hearing thresholds over the four-year period. The child’s opthamologist also reported an improvement in visual skills over time. The most interesting aspect of the child’s hearing was the discrepancy between the monaural and the binaural results. That is, when assessed binaurally she often presented with a mild to moderate mixed loss and when assessed monaurally she showed a moderate to severe mixed loss for the right ear and a severe mixed loss for the left ear. This discrepancy between binaural and monaural results was evident for both aided and unaided tests. Parental reports of the child’s hearing were consistent with the binaural clinical results. This case indicates the need for audiologists to: (a) carefully monitor the hearing of children with ACC, (b) obtain monaural and binaural hearing and aided thresholds results, and (c) compare these children’s functional abilities to the objective test results obtained. This case does question whether hearing aids are appropriate for children with ACC. If hearing aids are deemed to be appropriate, then hearing aids with compression characteristics should be considered.

Genetic and environmental contributions to cannabis dependence in a national young adult twin sample

Background. This paper examines genetic and environmental contributions to risk of cannabis dependence. Method. Symptoms of cannabis dependence and measures of social, family and individual risk factors were assessed in a sample of 6265 young adult male and female Australian twins born 1964-1971. Results. Symptoms of cannabis dependence were common: 11(.)0% of sample (15(.)1% of men and 7(.)8% of women) reported two or more symptoms of dependence. Correlates of cannabis dependence included educational attainment, exposure to parental conflict, sexual abuse, major depression, social anxiety and childhood conduct disorder. However, even after control for the effects of these factors, there was evidence of significant genetic effects on risk of cannabis dependence. Standard genetic modelling indicated that 44(.)7% (95% CI = 15-72(.)2) of the variance in liability to cannabis dependence could be accounted for by genetic factors, 20(.)1% (95 CI = 0-43(.)6) could be attributed to shared environment factors and 35(.)3% (95% CI = 26(.)4-45(.)7) could be attributed to non-shared environmental factors. However, while there was no evidence of significant gender differences in the magnitude of genetic and environmental influences, a model which assumed both genetic and shared environmental influences on risks of cannabis dependence among men and shared environmental but no genetic influences among women provided an equally good fit to the data. Conclusions. There was consistent evidence that genetic risk factors are important determinants of risk of cannabis dependence among men. However, it remains uncertain whether there are genetic influences on liability to cannabis dependence among women.

A Case Study of Partial Agenesis of the Corpus Callosum: Audiological Implications

This case study presents four and a half years of audiological observations, testing and aural habilitation of a female child with a partial agenesis of the corpus callosum (ACC). The ACC was diagnosed by MRI scan performed at 6 months of age to eliminate neurological causes for the developmental delay. This child was also born with a cleft palate and was diagnosed with Robinow Syndrome at 3 years and 3 months of age. The audiological results showed an improvement in hearing thresholds over the 4-year period. The child’s ophthalmologist also reported an improvement in visual skills over time. The most interesting aspect of the child’s hearing was the discrepancy between the monaural and the binaural results. That is, when assessed binaurally she often presented with a mild to moderate mixed loss and, when assessed monaurally, she showed a moderate to severe mixed loss for the right ear and a severe mixed loss for the left ear. Over time, the discrepancy between the monaural and binaural results changed. When assessed binaurally, the loss decreased to normal low frequency hearing sloping to a mild high frequency loss. When assessed monaurally, the most recent results showed a mild loss for the right ear and a moderate loss for the left ear. This discrepancy between binaural and monaural results was evident for both aided and unaided tests. For the most recent thresholds, the binaural results were consistent with the right monaural thresholds for the first time over the four and a half years. Parental reports of the child’s hearing were consistent with the binaural clinical results. This case indicates the need for audiologists to (1) carefully monitor the hearing of children with ACC, (2) obtain monaural and binaural hearing and aided thresholds results, and (3) compare these children’s functional abilities with the objective test results obtained. This case does question whether hearing aids are appropriate for children with ACC. If hearing aids are deemed to be appropriate, then hearing aids with compression characteristics should be considered.

Effect of periparturient diseases accompanied by excessive vulval discharge and weaning to mating interval on sow reproductive performance

Objective To evaluate the effect of periparturient disease accompanied by vulval discharge, and weaning-to-mating intervals, on sow fertility and litter size. Design Reproductive data were collected and analysed from 19 Hungarian swine herds over a 4 year period. Conception rates, farrowing rates and litter sizes of sows with periparturient disease accompanied by vulval discharge were used to evaluate the relationship between duration of vulval discharge and subsequent fertility and litter size. The possibility of interactions between weaning-to-mating intervals and duration of vulval discharges was investigated to determine if there was any effect on subsequent fertility and litter size. Results and conclusions Both parity 1 and parity 2 to 8 sows having had periparturient disease accompanied by vulval discharge in excess of 6 days duration had significantly (P < 0.001) lower subsequent fertility (conception, farrowing and adjusted farrowing rates) compared with sows of similar parity where the duration of vulval discharge was < 4 or 4 to 6 days. There was no difference in fertility rates between sows, in both parity categories, with vulval discharge for < 4 days compared with 4 to 6 days. A duration of vulval discharge in excess of 6 days in parity 1 sows significantly reduced litter size (total born and live-born) in subsequent farrowings, but not in parity 2 to 8 sows. There was no interaction between the duration of vulval discharge and post-weaning to mating intervals. However sows with weaning to mating intervals between 7 and 10 days had smaller (P < 0.001) subsequent litter sizes compared with 3 to 6 or 11 to 14 day intervals. It was concluded that the duration of vulval discharge in excess of 6 days was an indication of a severe persistent endometritis adversely affecting fertility of sows.

Alcohol, tobacco and breast cancer - collaborative reanalysis of individual data from 53 epidemiological studies, including 58 515 women with breast cancer and 95 067 women without the disease

Alcohol and tobacco consumption are closely correlated and published results on their association with breast cancer have not always allowed adequately for confounding between these exposures. Over 80% of the relevant information worldwide on alcohol and tobacco consumption and breast cancer were collated, checked and analysed centrally. Analyses included 58515 women with invasive breast cancer and 95067 controls from 53 studies. Relative risks of breast cancer were estimated, after stratifying by study, age, parity and, where appropriate, women's age when their first child was born and consumption of alcohol and tobacco. The average consumption of alcohol reported by controls from developed countries was 6.0 g per day, i.e. about half a unit/drink of alcohol per day, and was greater in ever-smokers than never-smokers, (8.4 g per day and 5.0 g per day, respectively). Compared with women who reported drinking no alcohol, the relative risk of breast cancer was 1.32 (1.19 - 1.45, P < 0.00001) for an intake of 35 - 44 g per day alcohol, and 1.46 (1.33 - 1.61, P < 0.00001) for greater than or equal to 45 g per day alcohol. The relative risk of breast cancer increased by 7.1% (95% CI 5.5-8.7%; P

Young women in conflict: Filipinas growing up in Australia

This paper discusses the tensions of adaptation as experienced by 72 young women, born in the Philippines or to immigrant mothers and resident in southeast, far west and far north Queensland, Australia. As illustrated, these women, aged 14-25 years, often have difficulty balancing their expectations with those of their families and of the society in which they live. Like most young Australians they experience some conflicts with parents, but the intersections of race, gender and culture may make it particularly difficult for young Filipinas to develop a sense of their own identity and place in society. The retention of Filipino values often isolates young women from their peers and excludes them from participating in activities considered an important part of growing up Australian, but the adoption of 'Australian' behaviors such as drinking and smoking is not necessarily accompanied by an enhanced sense of belonging.

Long-term trends in sunshine duration and its association with schizophrenia birth rates and age at first registration - data from Australia and the Netherlands

Back ground. Based on the well-described excess of schizophrenia births in winter and spring, we hypothesised that individuals with schizophrenia (a) would be more likely to be born during periods of decreased perinatal sunshine, and (b) those born during periods of less sunshine would have an earlier age of first registration. Methods. We undertook an ecological analysis of long-term trends in perinatal sunshine duration and schizophrenia birth rates based on two mental health registers (Queensland. Australia n = 6630; The Netherlands n = 24, 474). For each of the 480 months between 1931 and 1970, the agreement between slopes of the trends in psychosis and long-term sunshine duration series were assessed. Age at first registration was assessed by quartiles of long-term trends in perinatal sunshine duration, Males and females were assessed separately. Results. Both the Dutch and Australian data showed a statistically significant association between falling long-term trends in sunshine duration around the time of birth and rising schizophrenia birth rates for males only. In both the Dutch and Australian data there were significant associations between earlier age of first registration and reduced long-term trends in sunshine duration around the time of birth for both males and females, Conclusions. A measure of long-term trends in perinatal sunshine duration was associated with two epidemiological features of schizophrenia in two separate data sets. Exposures related to sunshine duration warrant further consideration in schizophrenia research. (C) 2002 Elsevier Science B.V. All rights reserved.

Special twin environments, genetic influences and their effects on the handedness of twins and their siblings

It has been suggested that twinning may influence handedness through the effects of birth order, intra-uterine crowding and mirror imaging. The influence of these effects on handedness (for writing and throwing) was examined in 3657 Monozygotic (MZ) and 3762 Dizygotic (DZ) twin pairs (born 1893-1992). Maximum likelihood analyses revealed no effects of birth order on the incidence of left-handedness. Twins were no more likely to be left-handed than their singleton siblings (n = 1757), and there were no differences between the DZ co-twin and sibling-twin covariances, suggesting that neither intra-uterine crowding nor the experience of being a twin affects handedness. There was no evidence of mirror imaging; the co-twin correlations of monochorionic and dichorionic MZ twins did not differ. Univariate genetic analyses revealed common environmental factors to be the most parsimonious explanation of familial aggregation for the writing-hand measure, while additive genetic influences provided a better interpretation of the throwing hand data.

Birth of Koalas Phascolarctos cinereus at Lone Pine Koala Sanctuary following artificial insemination

This paper documents the successful development of an artificial insemination (AI) programme for the Koala Phascolurctos cinereus. The protocols for trials involving two methods to induce ovulation and two insemination techniques are described. In Trial 1, interrupted coitus using a 'teaser'♂ successfully induced ovulation in nine Koalas. Five ♀♀ were inseminated while conscious using a modified 'foley catheter' (Cook insemination catheter) resulting in the births of two offspring. The other four ♀♀ were anaesthetized and inseminated using a technique which allowed visualization of the most cranial portion of the urogenital sinus, where semen was deposited using a 3.5 Fr. 'Tom-cat catheter' (urogen-itoscopic insemination). Three of the four ♀♀ inseminated by this technique produced pouch young. Microsatellite analysis of DNA from the pouch young excluded the teaser ♀♀ as possible sires, confirming that all offspring were sired by donor sperm. In Trial 2, eight ♀♀ were induced to ovulate by injecting them with 250 International Units of human chorionic gonadotrophin (hCG). A luteal phase was confirmed in all eight ♀♀ but only one gave birth following urogenitoscopic insemination. The Koala pouch young in this study are the first of any marsupial to be conceived and born following A1 procedures. Details of the A1 procedures used are presented and the significance of A1 to the conservation biology of P. cinereus discussed.

A estratégia como prática social : um estudo sobre a relação das práticas sociais dos gestores no “fazer estratégia” em uma empresa familiar

Este trabalho tem como objetivo compreender o “fazer estratégia” no seio de uma empresa familiar a partir das práticas sociais que envolvem os seus gestores. As práticas sociais são concebidas como um fenômeno social, o qual nasce e se desenvolve da interação e do relacionamento entre indivíduos em seu grupo social. Este grupo ou mundo social do indivíduo encontra-se em um processo constante de transformações em virtude da infinidade de interconexões sociais ali compartilhadas. Já o “fazer estratégia” apresenta-se aqui sob a ótica da estratégia como prática social que contempla “[...] como os praticantes de estratégia realmente agem e interagem [...]” (WHITTINGTON, 1996, p. 731), ou seja, a confluência entre as construções e práticas sociais cotidianas sobre seu “fazer estratégia”. A contemplação desses constructos teóricos possibilitou a formação de um esquema conceitual que por intermédio de um estudo de caso favoreceu o entendimento de “como as práticas sociais dos gestores se relacionam com o seu ‘fazer estratégia’ na empresa familiar?”. Para coleta de dados utilizou-se das técnicas: pesquisa documental, observação não-participante e entrevista semiestruturada (TRIVIÑOS, 1987). Os dados foram tratados através da técnica de Análise de Conteúdo na abordagem temática (BARDIN, 1977). Conclui-se com este estudo que as práticas sociais dos mais variados contextos nos quais os gestores da Empresa X se inserem, como o contexto familiar, interferem e se inter-relacionam diretamente no seu agir cotidiano e consequentemente no seu "fazer estratégia" a frente da empresa familiar, confirmando, estranhando e transformando a construção social dos sujeitos.

The Experience of the Religious through Silent Moving Image and the Silence of Bill Viola's Passions

With the creationof the moving image at the end of the 19th century a new way of representing and expressing the Religious was born. The cinema industry rapidly understood that film has a powerful way to attract new audiences and transformed the explicit religious message into an implicit theological discourse of the fictional film. Today, the concept of "cinema" needs to be rethought and expanded, as well as the notion of "tTranscendental" since the strong reality effect of the film can allow a true religious experience for the spectator.

Recovery of Trypanosoma forattinii Coutinho and Pattoli from a Trinidadian rodent

Recovery of Trypanosoma forattinii from natural infected Oryzomys capito velutinus from Trinidad, is reported. Negative results were obtained with attempts to infect experimentally, several laboratories animals, silvatyc rodents of the same ecological area and several species of triatomids bugs. Positive results were obtained only by using O. capito velutinus born in laboratory.

Mortalidade materna por cardiopatia

Realizou-se estudo retrospectivo da mortalidade materna por cardiopatia, no período de janeiro de 1979 a dezembro de 1989. Dentre um total de 16.423 internações, houve 694 gestantes com o diagnóstico de cardiopatia (4,2%). No mesmo período, ocorreram 51 óbitos maternos, correspondendo a um coeficiente de mortalidade materna de 428,2/100.000 nascidos vivos. Houve 12 óbitos maternos por cardiopatia. A análise estatística permitiu a identificação de alguns fatores associados a maior risco de morte nas pacientes cardiopatas: primeira gravidez, primiparidade, ausência de assistência pré-natal, realização de cirurgia cardíaca anterior à gravidez e/ou na gestação. O maior número de mortes ocorreu no puerpério. A classificação funcional (NYHA) não se constituiu em parâmetro seguro para avaliar o prognóstico materno, pois 91,7% dos casos de óbito foram incluídos no grupo considerado favorável (classes I e II) ao iniciar a gestação.

More than maternal sensitivity shapes attachment : infant coping and temperament

The aim of this longitudinal studywas to investigate the effect of a set of factors from multiple levels of influence: infant temperament, infant regulatory behavior, and maternal sensitivity on infant’s attachment. Our sample consisted of 48 infants born prematurely and their mothers. At 1 and 3 months of age, mothers described their infants’behavior using the Escala de Temperamento do Beb´e. At 3 months of age, infants’ capacity to regulate stress was evaluated during Tronick’s Face-to-Face Still-Face (FFSF) paradigm. At 9 months of age, mothers’ sensitivity was evaluated during free play using the CARE-Index. At 12 months of age, infants’ attachment security was assessed during Ainsworth’s Strange Situation. A total of 16 infants were classified as securely attached, 17 as insecure-avoidant, and 15 as insecure-resistant. Mothers of securely attached infantswere more likely than mothers of insecure infants to describe their infants as less difficult and to be more sensitive to their infants in free play. In turn, secure infants exhibited more positive responses during the Still-Face. Infants classified as insecureavoidant were more likely to self-comfort during the Still-Face and had mothers who were more controlling during free play. Insecure-resistant exhibited higher levels of negative arousal during the Still-Face and had mothers who were more unresponsive in free play. These findings show that attachment quality is influenced bymultiple factors, including infant temperament, coping behavior, and maternal sensitivity.
