Militares Medici in Nummis Repraesentati: The heritage of military

Coins and commemorative medals constitute one special repository of the history of military medicine. The numismatic record has proven to be the most enduring, albeit one of the most selective, records of the progress of history. Matters of health, and especially of military medicine, have been central to the endeavors and indeed the survival of many cultures and societies. Many such themes in the national and international history of military medicine are preserved in the medallic record. Coins and medallions thus constitute one record of the chronology of this profession, one parallel to that of the more traditional history to be found in oral and written records. This account presents a four-part classification of medical coins and medals of military interest. These examples include (1) medals that portray military surgeons and physicians; (2) medals that commemorate special events of military medicine; (3) coins that portray the themes of the discipline of military medicine and health; and (4) a miscellaneous group that includes such examples as disease touch pieces and the militarily worn medals of such bodies as the International Red Cross and the Order of St. John, the latter of which are awarded inter alia for contributions to prehospital care in the field. A representative photo archive of such exemplars is included in this account.

Communities of the postindustrial city

The authors discern the community structure of the postindustrial city, with reference to Australia. They focus empirically on three major types of Australian urban center: urban regions. metropolitan areas that are not part of urban regions, and other major cities. These three account for almost three-quarters of the Australian population. The authors draw on a conceptualization formulated by Marcuse and van Kempen to guide the analysis, with a combination of cluster analysis and discriminant analysis being applied to aggregate (essentially census) data to identify the communities. Nine major Australian urban communities are identified-four are affluent. four are disadvantaged. and one is a working-class community. The communities found, however, differed greatly from those cited in the Marcuse and van Kempen schema.

Role of the domestic chicken (Gallus gallus) in the epidemiology of urban visceral leishmaniasis in Brazil

Zoonotic visceral leishmaniasis (ZVL) is a serious public health problem in several Brazilian cities. Although the proximity of chicken houses is often cited as a risk factor in studies of urban ZVL, the role chickens play in the epidemiology of the disease has not been defined. Chickens attract both male and female sand flies (Lutzomyia longripalpis) but are unable to sustain Leishmania infections, and their presence may exert a zooprophylactic effect. We discuss environmental, physiologic, socioeconomic, and cultural factors related to chicken raising that could influence Le. infantum transmission in Brazilian cities and evaluate whether this practice significantly affects the risk of acquiring ZVL.

A pilot study of the manual force levels required to produce manipulation induced hypoalgesia

Objective. A pilot investigation of the influence of different force levels on a treatment technique's hypoalgesic effect. Design. Randomised single blind repeated measures. Background. Optimisation of such biomechanical treatment variables as the point of force application, direction of force application and the level of applied manual force is classically regarded as the basis of best practice manipulative therapy. Manipulative therapy is frequently used to alleviate pain, a treatment effect that is often studied directly in the neurophysiological, paradigm and seldom in biomechanical research. The relationship between the level of force applied by a technique (e.g. biomechanics) and its hypoalgesic effect was the focus of this study. Method. The experiment involved the application of a lateral glide mobilisation with movement treatment technique to the symptomatic elbow of six subjects with lateral epicondylalgia. Four different levels of force, which were measured with a flexible pressure-sensing mat, were randomly applied while the subject performed a pain free grip strength test. Results. Standardised manual force data varied from 0.76 to 4.54 N/cm, lower-upper limits 95 Cl, respectively. Pain free grip strength expressed as a percentage change from pre-treatment values was significantly greater with manual forces beyond 1.9 N/cm (P = 0.014). Conclusions. This study, albeit a pilot, provides preliminary evidence that in terms of the hypoalgesic effect of a mobilisation with movement treatment technique, there may be an optimal level of applied manual force.

Transcriptional regulation of the sodium-sulfate cotransporter NaSi-1 gene

Inorganic sulfate is one of the most abundant anions in mammalian plasma and is essential for proper cell growth and development, as well as detoxification and activation of many biological compounds. To date, little is understood how physiological levels of sulfate are maintained in the body. Our studies, and of others, have identified the NAS(i)-1 protein to be a functional sulfate transporter in the kidney and intestine, and due to this localization, constitutes a strong candidate gene for maintaining body sulfate homeostasis. Several factors, including hormones and metabolic conditions, have been shown to alter NAS(i)-1 mRNA and protein levels in vivo. In this study, we describe the transcriptional regulation of NaSi-1, with a focus on the mouse NaSi-1 gene (Nas1) that was recently cloned in our laboratory. Vitamin D (1,25-(OH)(2)D-3) and thyroid hormone (T-3) led to an increase in Nas1 promoter activity in OK cells. Mutational analysis of the Nas1 promoter resulted in identification of a direct repeat 6-type vitamin-D-responsive element (DR6 VDRE) at -525 to -508 and an imperfect inverted repeat 0-type T-3 responsive element (IRO T3RE) at -426 to -425 which conferred 1,25-(OH)(2)D-3 and T-3 responsiveness respectively. These findings suggest for vitamin D and thyroid hormone regulation of NaSi-1, may provide important clues to the physiological control of sulfate homeostasis.

Lactobacillus ruminis is a predominant lactic acid producing bacterium in the caecum and rectum of the pig

Aims: To identify the predominant lactic acid producing bacteria in the small intestine, caecum and the rectum of the healthy pig. Methods and Results: Samples obtained from the large intestine of healthy pigs post-mortem were cultured using a modified agar-MRS medium in roll tubes. Thirteen isolates were selected on the basis of their morphological characteristics and Gram stain reaction for gene sequencing. These isolates were characterized by DNA sequence analysis of 16S rDNA. Eight isolates were identified as Lactobacillus ruminis , two as Enterococcus faecium , one as Mitsuokella multiacidus and two as Escherichia coli . Conclusion: This is the first report of Lact. ruminis as the dominant lactic acid bacteria in the large intestine of the pig. Significance and Impact of the Study: The results suggest that Lact. ruminis is a dominant bacterium in the large intestine of the healthy pig. Future work should focus on the role of this bacterium in relation to the physiological function of the intestine and the health of the animal.

At-risk children: A demographic analysis of the children of clients attending mental health community clinics

Children of parents with mental illness have an increased risk of psychological problems. The aim of this study was to identify the demographic characteristics of dependent children of adults presenting at mental health clinics in Western Australia. A survey of clients who attended the clinics indicated that half reported having had children. Of these, 21% had a primary diagnosis of schizophrenia. Although schizophrenia was the most common illness, there were almost seven times more children living with a parent with a primary diagnosis of depression than schizophrenia. Recommendations include that children of clients with mental illness be included as part of a wider client focus.
