La mucormycose nasosinusienne: Diagnostic et modalites therapeutiques

La mucormycose est une infection fongique rare qui touche essentiellement les sujets immunodéprimés et notamment diabétiques. La localisation de cette maladie est surtout nasosinusienne. Son pronostic reste mauvais malgré le développement des moyens de prise en charge. Nous rapportons deux cas de mucormycose nasosinusienne à travers lesquels nous discutons les aspects cliniques et radiologiques, ainsi que les moyens thérapeutiques de cette maladie. Il s’agit d’un homme et d’une femme âgés respectivement de 56 et 52 ans. Le premier était diabétique et la deuxième insuffisante rénale. L’évolution était lente dans le premier cas et très rapide dans le deuxième. Le diagnostic était dans les deux cas histologique. L’évolution était, dans le premier cas, favorable après traitement associant débridement chirurgical et amphotéricine B, et dans le second rapidement fatale. Conclusion : La mucormycose nasosinusienne est une affection grave dont le pronostic peut être mauvais malgré le traitement.Mots clés : Infection fongique, mucormycose rhinocérébrale, zygomycètes

Detecting the Effects of Changes on the Compliance of Cross-organizational Business Processes

An emerging challenge for collaborating business partners is to properly define and evolve their cross-organizational processes with respect to imposed global compliance rules. Since compliance verification is known to be very costly, reducing the number of compliance rules to be rechecked in the context of process changes will be crucial. Opposed to intra-organizational processes, however, change effects cannot be easily assessed in such distributed scenarios, where partners only provide restricted public views and assertions on their private processes. Even if local process changes are invisible to partners, they might affect the compliance of the cross-organizational process with the mentioned rules. This paper provides an approach for ensuring compliance when evolving a cross-organizational process. For this purpose, we construct qualified dependency graphs expressing relationships between process activities, process assertions, and compliance rules. Based on such graphs, we are able to determine the subset of compliance rules that might be affected by a particular change. Altogether, our approach increases the efficiency of compliance checking in cross-organizational settings

Testicular tumours in prepubertal children: About eight cases

Background: To analyze the spectrum of testicular tumors in prepubertal children and the therapeutic resultants in an unselected population. Materials and Methods: Our hospital database was analyzed for testicular tumors from January 1995 to December 2010 concerning clinical presentation, treatment and therapeutic results. Results: Eight patients were operated on because of testicular tumors.In six cases (75%) the tumor was benign: benign teratoma (four cases), epidermoid cyst (one case) and immature teratoma (one case). Two  patients (25%) had a malignant tumour: yolk-sac tumour (two cases). All this children underwent surgery. Radical inguinal orchidectomy was  performed in six cases and conservative surgery was performed in two cases. One patient has received adjuvant chemotherapy. Followup was uneventfully three years after primary surgery.Conclusion: In prepubertal children, most testicular tumours are benign. If tumour markers were negative testis-preserving surgery can be proposed,  complete excision of the tumour should be ascertained. In the case of testicular teratoma, the possibility of contralateral tumour should be    considered in the follow-up.Key words: Children, Testis, Tumour, Teratoma,yolk-sac tumou

Enhancing Business Process Flexibility by Flexible Batch Processing

Business Process Management is a powerful approach forthe automation of collaborative business processes. Recently conceptshave been introduced to allow batch processing in business processesaddressing the needs of different industries. The existing batch activityconcepts are limited in their flexibility. In this paper we contribute differentstrategies for modeling and executing processes including batch workto improve the flexibility 1) of business processes in general and 2) of thebatch activity concept. The strategies support different flexibility aspects(i.e., variability, looseness, adaptation, and evolution) of batch activities.The strategies provide a systematic approach to categorize existing andfuture batch-enabled BPM systems. Furthermore, the paper provides asystem architecture independent from existing BPM systems, which allowsfor the support of all the strategies. The architecture can be usedwith different process languages and existing execution environments ina non-intrusive manner
