    Notes: The inactivation kinetics of food poisoning microorganisms using a combined treatment of carbon dioxide (CO2) with high hydrostatic pressure (HHP) was investigated. Staphylococcus aureus, Fusarium oxysporum, and Fusarium sporotrichioides were totally inactivated by a combined treatment of carbonation and HHP at 500 MPa. Bacillus subtilis, a spore forming bacteria, were not completely inactivated after the combined treatment. The microorganisms treated by carbonation and HHP were exponentially reduced in a pressure range and the Dp -value, the Zp-value, and the activation volume were determined. UV absorbing materials leaked from injured cells. Morphological changes of the cells were observed by scanning and transmission electron microscopy.

    Notes: Background Although asthma is a common cause of morbidity in adults, relatively few objectively measured population studies of asthma prevalence in adult populations have been conducted.Objective To evaluate the prevalence of asthma, based on both a questionnaire and methacholine bronchial provocation test, and to determine the risk factors of asthma prevalence in an adult population.Methods A total of 2467 adults, who were randomly selected from metropolitan urban, non-metropolitan urban and rural areas, responded to the modified ISAAC questionnaire, and underwent methacholine bronchial provocation tests and skin prick tests to locally common aeroallergens.Results The prevalence of current asthma based on the questionnaire and the methacholine challenge was 2.0% in adults younger than 40, 3.8% in 40- to 54-year-olds, 7.7% in 55- to 64-year-olds and 12.7% in those aged 65 or higher. For subjects of 55–64 years, active smoking was found to be significantly related with the prevalence of current asthma and bronchial hyper-responsiveness, although smoking was positively associated with percentage predictive value of forced expiratory volume of 1 s (FEV1).Conclusion The prevalence of current asthma is common among the elderly, and active smoking may play an important role in the development of asthma and bronchial hyper-responsiveness among the elderly.

    Notes: Postwar trends in international communication research reveal that the three main paradigms-modernization, dependency, and postdependency-have theoretical and methodological limitations for analyzing the complexities of cultural practices in the contemporary era. The limitations arise from the narrow theoretical concern centered on the polarity between development and dependency, and the overemphasis of economic forces at the expense of cultural forces. In this essay I urge a focus on cultural dynamics to reflect rapidly changing conditions of integration and disintegration among diverse cultural forces in a global society. The concepts and methods in postmodern cultural studies can facilitate this theoretical shift. The Gramscian concept of hegemony allows us to explore the economic aspect of cultural production by media industries and the cultural ideological aspect of audience readings within a single research framework.

    Description / Table of Contents: Résumé. Les auteurs rapportent un cas d’amputation post-traumatique de la partie haute de jambe chez une femme de 29 ans. Le but de l’étude était d’évaluer le résultat de l’allongement du moignon d’amputation réalisé pour amèliorer l’ajustage d’une prothèse. Après échec par infection d’une greffe de l’extrêmité distale du tibia, le moignon était resté trop court pour permettre l’utilisation d’une prothèse conventionnelle. Les parties molles étaient restées suffisantes grâce à un lambeau muscolo-cutané utilisant le muscle jumeau et la coque talonnière. Bien qu’il y eut quelques problèmes de douleurs et d’inflammation sur les fiches, l’allongement osseux obtenu par la technique d’Ilizarov a été finalement un succès permettant une augmentation de longueur de 7 cms (127% d’augmentation). Pendant la période d’allongement, l’appui sur le membre inférieur a été possible.
    Notes: Summary. A woman, 29 years of age, sustained a below knee amputation following injury and was left with a stump 5.5 cm long. Good soft tissue cover was obtained with a myocutaneous flap using the gastrocnemius muscle and heel pad flap from the injured leg. The stump was then lengthened by 7 cm, to 12.5 cm, using the Ilizarov distraction technique. The patient was able to bear weight on the end of the fixator during the 8 months it was in position. The gap filled with bone and there were no complications. She recovered good function.

    Description / Table of Contents: Résumé. Les dommages osseux importants dans les fractures ouvertes du Tibia sont généralement traités par une greffe osseuse conventionelle: on utilise soit une greffe de péroné vascularisée, soit la technique du fixateur (type llizarov). Une greffe de péroné vascularisée peut être meilleure qu’une greffe osseuse conventionnelle, mais c’est une greffe qui est techniquement, difficile et parfois impossible à réaliser. Dans ce cas, le transfert du péroné avec l’utilisation du fixateur externe (type Ilizarov) est une méthode alternative. Cette opération peut être accomplie en transférant la partie ostéotomisée du péroné sur le Tibia au moyen de cables «olives». Récemment, un jeune homme de 20 ans a présenté une fracture ouverte du Tibia de type Gustilo IIIb. Les dommages causés aux tissues étaient sévères. Seule l’artère tibiale postérieure était perméable et l’artère péronéale était partiellement endommagée. Un recouvrement par lambeau de grand dorsal fût réalisé afin de couvrir les tissues endommagés. Le seule artère tibiale postérieure étant déjà utilisé pour le recouvrement, il était difficile de réaliser une greffe de péroné vascularisée. De plus il était techniquement difficile d’accomplir un déplacement graduel en utilisant la fixateur externe (type Ilizarov) car la partie distale du Tiba était perdue. Ainsi, un transfert de péroné fût immédiatement réalisé avoir appliqué le fixateur externe. Une bonne fusion osseuse, ainsi qu’une hypertrophie du péronée ont été obtenues, bien que ces 2 opérations aient été effectuées simultanément.
    Notes: Abstract. Massive segmental bony defects in open tibial fractures are generally treated with conventional bone grafting, a free vascularised fibular graft or the ring fixator technique. A vascularised fibular graft may be superior to a conventional bone graft, but it is technically difficult and occasionally impossible. In such circumstances, fibular transfer in conjunction with a ring fixator is an alternative method. This procedure can be accomplished by transferring the osteotomised part of the fibula to the tibia by means of olive wires. The authors have treated a 20-year-old male who presented with a Gustilo type IIIB open tibial fracture. The soft tissue defect was severe, only the tibialis posterior artery was patent and the peroneal artery was partially damaged. A latissimus dorsi flap was performed to cover the soft tissue defect. Since the patent tibialis posterior artery had already been used for the flap, it was difficult to perform a vascularised fibular graft. Moreover, it was technically difficult to accomplish a gradual transport using a ring fixator because the distal tibia was lost. For this reason, the fibular transfer was performed immediately after the ring fixator was applied. Good bony union and fibular hypertrophy were obtained even though these two procedures were undertaken simultaneously.

    Description / Table of Contents: Résumé Le fixateur externe Orthofix a été utilisé pour le traitement de 112 fractures diaphysaires chez 101 patients et chez 22 malades porteurs de pseudarthroses infectées. Nos résultats peuvent se comparer favorablement avec ceux qui sont rapportés dans d'autres séries où le fixateur externe a été employé. Le pourcentage total de consolidations sans complication a été de 69.6%, avec 24.1% de patients chez qui une opération complémentaire a été nécessaire. Le taux global de pseudarthroses (30.4%) est dû au nombre relativement important de fractures ouvertes graves dans cette série. L'appareil est facile à poser, sûr et efficace en pratique. Nous le recommandons dans le traitement initial des fractures ouvertes et des fractures comminutives, ainsi que dans les pseudarthroses infectées.
    Notes: Summary The Orthofix external fixator was used to treat 112 fractures of the long bones in 101 patients, and 22 patients with infected nonunions. Our results compared favourably with those reported in other series where external fixation was used. The overall rate of uncomplicated union was 69.6% with 24.1% of patients requiring a further operation. The overall incidence of nonunion (30.4%) was due to the relatively large number of severe open fractures in the series. The apparatus was simple to apply, and safe and effective in practice. We recommend its use for the primary treatment of open and segmental fractures, and for infected nonunion.

    Notes: Abstract  Mutational analysis of the COL4A5 gene in X-linked Alport syndrome (AS) requires an expensive and time-consuming procedure with a detection rate of 50%, at best. There have been three multicenter collaborative studies of mutation analysis in the COL4A5 gene using systematic screening of entire coding regions of the gene. This is a similar study executed in a single center in Korea. Twenty-five unrelated Korean patients with AS in whom the diagnosis was confirmed pathologically were included in the study. By systematic screening of all 51 exons of the gene using polymerase chain reaction/single-strand conformation polymorphism analysis, ten mutations were detected in 10 unrelated patients. These included one medium-sized deletion involving exon 49–51, one single base pair deletion, one nonsense point mutation, one splice site mutation, and six missense point mutations. Of the six missense mutations, four involved a glycine residue and disrupted the Gly-X-Y repeats in the collagenous domain. The overall detection rate of mutations was 40%. Although DNA analysis in AS is currently not applicable to routine clinical diagnosis due to several practical and technical problems, it is likely to replace morphological diagnosis in the near future.
