Maladie de Castleman: Localisation inhabituelle du thorax

La maladie de Castleman est une affection rare qui peut toucher le thorax. La localisation diaphragmatique est exceptionnelle. Nous rapportons le cas d’une patiente de 47 ans, chez qui une thoracotomie exploratrice a permis l’exérèse d’une masse du sinus médiastinal antérieur droit, en continuité avec le diaphragme et dont l’histologie est en faveur de la maladie de Castleman de type hyalino-vasculaire. Les particularités cliniques,radiologiques et évolutives ont été revues.Key words: Maladie de Castleman, localisation, thorax, exérèse, chirurgi

Les tumeurs desmoides de la paroi thoracique : à propos de 12 cas

Introduction: Les tumeurs desmoides sont des tumeurs rares des tissus mous qui peuvent être très agressives localement. A travers l’expérience de notre service, nous analyserons les résultats du traitement chirurgical de ces tumeurs. Patients et méthodes: De 1980 à 2008, 12 patients ont été opérés pour tumeur desmoide de la paroi thoracique. Le diagnostic a été suspecté sur la base des signes cliniques et radiologiques. Aucun patient n’avait un syndrome de Gardner. L’abord chirurgical a été souvent électif à l’aplomb de la tumeur. Résultats: La résection a été complète dans 11 cas. La confirmation diagnostique a été apportée par l’étude histologique de la pièce opératoire. La durée du suivi post opératoire variait entre 24 et 180 mois. Une patiente était décédée par insuffisance cardiaque et rénale. 7 cas avaient récidivé, et qui ont été traités par simple résection complète dans 5 cas, dont un avait nécessité une greffe myocutanée ; par ailleurs, deux cas ont été traités par résection incomplète associée à une radiothérapie adjuvante. Conclusion: La chirurgie des tumeurs desmoides de la paroi thoracique doit être aussi large que possible pour diminuer le risque de récidive

Hydatid disease of the ribs: An exceptional location

Background. Hydatid disease is a zoonosis caused by larval stages of cestodes belonging to the genus Echinococcus. The rib location is exceptional. It presents a real diagnostic and therapeutic challenge. Objective. To describe the clinical, serological and radiological features and surgical management of rib hydatidosis. Methods. This is a retrospective study conducted over 4 years, on five cases of rib hydatidosis. We analysed the clinical and radiological presentations and the adopted therapeutic procedure. Results. The average age of our patients was 44 years, without gender predominance. The clinical signs were dominated by the presence of an immobile swelling of fluid consistency without inflammatory sign, accompanied by moderate and intermittent localised pain. The laboratory assessment was nonspecific. The radiological assessment, including chest X-ray and thoracic computed tomography, with and without contrast, was essential in order to assess the extent of the lesion. Thoracic magnetic resonance imaging was requested in one case because of suspicions of a spinal extension. All of our patients underwent a rib excision accompanied by medical treatment of albendazole 24 hours after the surgery. The follow-up ranged from 1 year to 4 years and did not show any recurrence. Conclusion. Hydatidosis of the ribs is an exceptional location of hydatid disease. The diagnosis was based on radiology and intraoperative exploration. The treatment remained essentially surgical by rib excision with anthelmintic drugs to prevent recurrence

Cavernostomy x Resection for Pulmonary Aspergilloma: A 32-Year History

<p>Abstract</p> <p>Background</p> <p>The most adequate surgical technique for the treatment of pulmonary aspergilloma is still controversial. This study compared two groups of patients submitted to cavernostomy and pulmonary parenchyma resection.</p> <p>Methods</p> <p>Cases of pulmonary aspergilloma operated upon between 1979 and 2010 were analyzed retrospectively. Group 1 consisted of patients submitted to cavernostomy and group 2 of patients submitted to pulmonary parenchyma resection. The following variables were compared between groups: gender, age, number of hospitalizations, pre- and postoperative length of hospital stay, time of follow-up, location and type of aspergilloma, preoperative symptoms, underlying disease, type of fungus, preoperative pulmonary function, postoperative complications, patient progression, and associated diseases.</p> <p>Results</p> <p>A total of 208 patients with pulmonary aspergilloma were studied (111 in group 1 and 97 in group 2). Group 1 was older than group 2. The number of hospitalizations, length of hospital stay and time of follow-up were higher in group 1. Hemoptysis was the most frequent preoperative symptom in group 1. Preoperative respiratory malfunction was more severe in group 1. Hemorrhagic complications and recurrence were more frequent in group 1 and infectious complications and residual pleural space were more common in group 2. Postoperative dyspnea was more frequent in group 2. Patient progression was similar in the two groups. No difference in the other factors was observed between groups.</p> <p>Conclusions</p> <p>Older patients with severe preoperative respiratory malfunction and peripheral pulmonary aspergilloma should be submitted to cavernostomy. The remaining patients can be treated by pulmonary resection.</p

Inclusionary control? Theorizing the effects of penal voluntary organizations’ work

Recent penal policy developments in many jurisdictions suggest an increasing role for voluntary organizations. Voluntary organizations have long worked alongside penal institutions, but the multifaceted ways their programmes affect (ex-)offenders remain insufficiently understood. This article addresses the implications of voluntary organizations’ work with (ex-)offenders, using original empirical data. It adds nuance to netwidening theory, reframing the effects of voluntary organizations’ work as inclusionary and exclusionary. Exclusionary effects sometimes have inclusionary aspects, and inclusionary effects are constrained by a controlling carceral net. We propose the novel concept of inclusionary control. This is not an alibi for punishment but enables rich analysis of the effects of voluntary organizations’ work, and raises possibilities for change in penal practice

Affinity-Purified Respiratory Syncytial Virus Antibodies from Intravenous Immunoglobulin Exert Potent Antibody-Dependent Cellular Cytotoxicity

Mixed infections are one of the major therapeutic challenges, as the current strategies have had limited success. One of the most common and widespread conditions of mixed infection is respiratory syncytial virus-mediated pathology of the respiratory tract in children. There is a dire need for the development of novel therapeutic approaches during mixed infections. Therapeutic intravenous immunoglobulin preparations, obtained from plasma pools of healthy donors have been used in immune deficiencies. This study was thus designed to characterize the functional efficacy of RSV-specific antibodies in IVIg. To explore the functional ability of these affinity-purified RSV-specific antibodies, the antibody-dependent and complement dependent cytotoxicity was determined using peripheral cells of healthy donors. This study demonstrates the existence of highly potent RSV-specific antibodies in IVIg preparations and provides the basis for the use of IVIg as broad-spectrum protective shield to RSV-infected children during mixed infections
