BACKGROUND: The provision of sufficient basal insulin to normalize fasting plasma glucose levels may reduce cardiovascular events, but such a possibility has not been formally tested. METHODS: We randomly assigned 12,537 people (mean age, 63.5 years) with cardiovascular risk factors plus impaired fasting glucose, impaired glucose tolerance, or type 2 diabetes to receive insulin glargine (with a target fasting blood glucose level of ≤95 mg per deciliter [5.3 mmol per liter]) or standard care and to receive n-3 fatty acids or placebo with the use of a 2-by-2 factorial design. The results of the comparison between insulin glargine and standard care are reported here. The coprimary outcomes were nonfatal myocardial infarction, nonfatal stroke, or death from cardiovascular causes and these events plus revascularization or hospitalization for heart failure. Microvascular outcomes, incident diabetes, hypoglycemia, weight, and cancers were also compared between groups. RESULTS: The median follow-up was 6.2 years (interquartile range, 5.8 to 6.7). Rates of incident cardiovascular outcomes were similar in the insulin-glargine and standard-care groups: 2.94 and 2.85 per 100 person-years, respectively, for the first coprimary outcome (hazard ratio, 1.02; 95% confidence interval [CI], 0.94 to 1.11; P=0.63) and 5.52 and 5.28 per 100 person-years, respectively, for the second coprimary outcome (hazard ratio, 1.04; 95% CI, 0.97 to 1.11; P=0.27). New diabetes was diagnosed approximately 3 months after therapy was stopped among 30% versus 35% of 1456 participants without baseline diabetes (odds ratio, 0.80; 95% CI, 0.64 to 1.00; P=0.05). Rates of severe hypoglycemia were 1.00 versus 0.31 per 100 person-years. Median weight increased by 1.6 kg in the insulin-glargine group and fell by 0.5 kg in the standard-care group. There was no significant difference in cancers (hazard ratio, 1.00; 95% CI, 0.88 to 1.13; P=0.97). CONCLUSIONS: When used to target normal fasting plasma glucose levels for more than 6 years, insulin glargine had a neutral effect on cardiovascular outcomes and cancers. Although it reduced new-onset diabetes, insulin glargine also increased hypoglycemia and modestly increased weight. (Funded by Sanofi; ORIGIN ClinicalTrials.gov number, NCT00069784.).

OBJECTIVE: The European Panel on the Appropriateness of Crohn's disease Therapy (EPACT) has developed appropriateness criteria. We have applied these criteria retrospectively to the population-based inception cohort of Crohn's disease (CD) patients of the European Collaborative Study Group on Inflammatory Bowel Disease (EC-IBD). MATERIAL AND METHODS: A total of 426 diagnosed CD patients from 13 European centers were enrolled at the time of diagnosis (first flare, naive patients). We used the EPACT definitions to identify 247 patients with active luminal CD. We then assessed the appropriateness of the initial drug prescription according to the EPACT criteria. RESULTS: Among the cohort patients 163 suffered from mild-to-moderate CD and 84 from severe CD. Among the mild-to-moderate disease group, 96 patients (59%) received an appropriate treatment, whereas for 66 patients (40%) the treatment was uncertain and in one case (1%) inappropriate. Among the severe disease group, 86% were treated medically and 14% required surgery. 59 (70%) were appropriately treated, whereas for one patient (1%) the procedure was considered uncertain and for 24 patients (29%) inappropriate. CONCLUSION: Initial treatment was appropriate in the majority of cases for non-complicated luminal CD. Inappropriate or uncertain treatment was given in a significant minority of patients, with an increased potential risk of adverse events.

PURPOSE: To report the clinical and genetic study of two families of Egyptian origin with clinical anophthalmia. To further determine the role of the retina and anterior neural fold homeobox gene (RAX) in anophthalmia and associated cerebral malformations. METHODS: Three patients with clinical anophthalmia and first-degree relatives from two consanguineous families of Egyptian origin underwent full ophthalmologic, general and neurologic examination, and blood tests. Cerebral magnetic resonance imaging (MRI) was performed in the index cases of both families. Genomic DNA was prepared from venous leukocytes, and direct sequencing of all the exons and intron-exon junctions of RAX was performed after PCR amplification. RESULTS: Clinical bilateral anophthalmia was observed in all three patients. General and neurologic examinations were normal; obesity and delay in psychomotor development were observed in the isolated case. Orbital MRI showed a hypoplastic orbit with present but rudimentary extraocular muscles and normal lacrimal glands. Cerebral MRI showed agenesis of the optic nerves, optic tracts, and optic chiasma. In the index case of family A, the absence of the frontal and sphenoidal sinuses was also noted. In the index case of family B, only the sphenoidal sinus was absent, and there was significant cortical atrophy. The three patients carried a novel homozygous c.543+3A>G mutation (IVS2+3A>G) in RAX. Parents were healthy heterozygous carriers. No mutations were detected in orthodenticle homeobox 2 (OTX2), ventral anterior homeobox 1 (VAX1), or sex determining region Y-box 2 (SOX2). CONCLUSIONS: This is the first report of a homozygous splicing RAX mutation associated with autosomal recessive bilateral anophthalmia. To our knowledge, only two isolated cases of anophthalmia, three null and one missense case affecting nuclear localization or the DNA-binding homeodomain, have been found to be caused by compound heterozygote RAX mutations. A novel missense RAX mutation was identified in three patients with bilateral anophthalmia and a distinct systemic and neurologic phenotype. The mutation potentially affects splicing of the last exon and is thought to result in a protein that has an aberrant homeodomain and no paired-tail domain. Functional consequences of this change still need to be characterized.

Résumé de thèse ,,Aspekte des Erzählens in der ,Melusine' Thürings von Ringoltingen. Dialoge, Zeitstruktur und Medialität des Romans" Im Mittelpunkt der Arbeit steht der 1456 abgeschlossene Prosaroman ,Melusine' des Berner Patriziers Thüring von Ringoltingen. Geforscht wurde ausgehend von einem ausgewählten Überlieferungszeugen, dem mit 67 Holzschnitten ausgestatteten Basler Erstdruck des Bernhard Richel von 1473/74. Als Instrumentarium des Forschungsvorhabens dient die aus der Fusion linguistischer und komparatistischer Arbeitsweisen neu kreierte Theorie der ,,analyse textuelle et comparative des discours" von Adam und Heidmann (Kap. 1). In Kap. 2 und 3 wird die Rolle des den Stoff organisierenden Erzählers untersucht. Kap. 2 bietet in diesem Rahmen Überlegungen zur historischen Semantik von materye und hystorie, während Kap. 3 die narrative Handhabung der Erzählchronologie analysiert. Dabei stehen die zahlreichen Vorausdeutungen und Rückblenden im Zentrum, die der Erzähler in seinen Roman einflicht. Untersucht wird, wie sich diese zum analytischen Erzählaufbau verhalten. Gezeigt wird ferner, wie der Erzähler bei Thüring negativ gefärbte Vorausdeutungen raffiniert zu einer gegenüber Coudrette neuen Textausssage einsetzt, indem er sie mit dem vom Berner Autor neu in den Text eingefügten Augustinusexemplum vernetzt. Detaillierte Anhänge zu den Pro- und Analepsen dokumentieren die Parallelen und Unterschiede zwischen Thürings und Coudrettes ,Melusine'. In Kap. 4 werden die erzählungsimmanenten Dialoge in direkter Rede analysiert (mit Exkursen zur Relation zwischen Sehen und Sprechen sowie den Stilregistern der Höflichkeit, soweit sie sich in den Dialogen abzeichnen). Mit Rückgriff auf Methoden der linguistischen Dialoganalyse werden im Rahmen eines close-reading die langen Dialoge exemplarisch untersucht. Beleuchtet werden die Zusammenhänge, in denen Figurenrede direkt wiedergegeben wird. Des weiteren wird die Art und Weise analysiert, mit der sich Dialoge in direkter Rede in die textliche Umgebung einfügen bzw. mit Passagen indirekter Rede oder mit Erzählerrede kombiniert sind. Schliesslich interessiert die Frage, inwiefern die sich in der verbalen Interaktion zwischen den Protagonisten widerspiegelnde Beziehung Aufschluss zum Verhältnis der Figuren untereinander geben kann und damit Interpretationsansätze für den Roman insgesamt bereitstellt. Kap. 5 untersucht die Text-Bild-Verhältnisse in der Richel-Inkunabel. Mit dem Ziel zu sehen, wie die Präsentation des Romans in der Inkunabel die Rezeption von Thürings Text möglicherweise beeinflusst, galt das Augenmerk den folgenden drei Teilbereichen, die jeweils mit einem Anhang belegt sind: 1. Vergleich der Struktur, die der Roman auf der einen Seite durch den Stoff und durch die Erzählerinterventionen erhält und die auf der anderen Seite durch die Präsenz der Bilder und der Bildbeischriften zustande kommt. 2. Untersuchung des Dreiecksverhältnisses von Bild, Text und Titulus. Es interessierte die Frage, welche Elemente der Romanhandlung in der jeweiligen Kategorie auftreten und wo Bild und/oder Bildbeischrift allenfalls zusätzliche resp. weniger Informationen bereitstellen als der Romantext selbst. 3. Untersuchung der Eingliederung von Bild und Titulus in den Romantext. Analysiert wurde, wie Bild und Bildbeischrift gegenüber dem Romantext an manchen Stellen Informationen bereits vorwegnehmen, oder im Gegenteil Informationen nachschieben. Insgesamt ist die Dissertation ist in der Nachfolge der Untersuchungen Hans-Geit Roloffs zu sehen, wobei rund 40 Jahre Forschungsgeschichte zwischen den ,,Stilstudien" Roloffs und der hier präsentierten Untersuchung liegen. Ziel war es, an die Studien Roloffs anzuknüpfen, diese kritisch zu lesen und um neue Perspektiven zu erweitern, die über den unmittelbaren Vergleich zwischen Thürings ,Melusine' und seiner französischen Vorlage hinausgehen.

Pooled F(ab')2 fragments of three MAbs against distinct epitopes of carcinoembryonic antigen (CEA) were used for radioimmunotherapy of nude mice bearing a subcutaneous human colon carcinoma xenograft. 9-10 d after transplantation when tumor nodules were in exponential growth, 36 mice were treated by intravenous injection of different amounts of 131I-labeled MAb F(ab')2. All 14 mice injected with a single dose of 2,200 (n = 10) or 2,800 microCi (n = 4) showed complete tumor remission. 8 of the 10 mice treated with 2,200 microCi survived in good health for 1 yr when they were killed and shown to be tumor free. Four of nine other mice treated with four fractionated doses of 400 microCi showed no tumor relapse for more than 9 mo. In contrast, all 15 mice injected with 1,600-3,000 microCi 131I-control IgG F(ab')2 showed tumor growth retardation of only 1-4 wk, and 15 of 16 mice injected with unlabeled anti-CEA MAb F(ab')2 showed unmodified tumor progression as compared with untreated mice. From tissue radioactivity distributions it was calculated that by an injection of 2,200 microCi 131I-MAb F(ab')2 a mean dose of 8,335 rad was selectively delivered to the tumor, while the tissue-absorbed radiation doses for the normal organs were: peripheral blood, 2,093; stomach, 1,668; kidney, 1,289; lung, 1,185; liver, 617; spleen, 501; small intestine, 427; large intestine, 367; bone, 337; and muscle, 198. These treatments were well tolerated since out of 19 mice with complete tumor remission only 4 required bone marrow transplantation and 17 were in good health for 6-12 mo of observation. The results demonstrate the selective destruction of established human colon carcinoma transplants by intravenous injection of either single or fractionated doses of 131I-MAb F(ab')2.

Pulmonary alveolar proteinosis (PAP) is characterized by accumulation of lipoproteinaceous material in the terminal airways. Whole lung lavage (WLL) remains the gold standard treatment but may be particularly challenging in cases of severe hypoxemia. We present a 3-step strategy that was used in a patient with PAP-associated refractory hypoxemia and that combined venovenous extracorporeal membrane oxygenation (vvECMO), double-lumen orotracheal intubation, and bilateral multisegmental sequential lavage (MSL). The procedure was well tolerated and permitted weaning from the ventilator.

Le syndrome douloureux fémoro-patellaire (SDFP) est l'une des causes les plus fréquentes de douleur antérieure du genou chez l'adolescent et l'adulte. De par son étiologie complexe, multifactorielle et encore mal comprise, sa prise en charge est un important challenge pour le praticien. Le diagnostic se fait principalement sur l'anamnèse et l'examen clinique du genou mais aussi de l'ensemble du membre inférieur, pouvant parfois nécessiter la réalisation d'une imagerie. Le traitement est dans la grande majorité des cas conservateur, principalement axé sur la rééducation avec de la physiothérapie ciblée et personnalisée. Le traitement chirurgical est réservé aux cas présentant une anomalie structurelle causale. Patellofemoral pain syndrome (PFPS) is one of the most frequent cause of anterior knee pain in adolescents and adults. Due to its complex etiology, which is multifactorial and still poorly understood, its management is a major challenge for the practitioner. The diagnosis is made primarily on the history and clinical examination of the knee, but also of the entire lower limb, which may sometimes require the completion of imaging. The treatment is mostly conservative, focussing on rehabilitation with targeted and personalized therapy. Surgical treatment is reserved for cases with a causal structural lesion.
