[Functional results and prognostic factors in open-globe ocular trauma with presenting visual acuity of no-light perception]. / Résultats fonctionnels et facteurs pronostiques des traumatismes oculaires à globe ouvert avec acuité visuelle initiale à perception lumineuse négative.

PURPOSE: To analyse the clinical ocular characteristics and determine prognostic factors for functional recovery in eyes presenting with no light perception (NLP) after open globe ocular trauma. MATERIALS AND METHODS: In this retrospective study were included all the patients with no light perception after open globe trauma who presented to Amiens University Hospital between October 2014 and June 2018. RESULTS: Fifteen eyes of 15 patients were included in this study. The main mechanism of the trauma was globe rupture (80 %, n=12). The most common location was zone III (66 %, n=10). The wound size was greater than 10mm in 9 patients (60 %). The ocular lesions included expulsion of the crystalline lens or posterior chamber intraocular lens, hyphema, retinal detachment, vitreous hemorrhage and ciliochoroidal lesions. Damage to the ciliary body was a negative prognostic factor for functional recovery (P=0.04). Nine patients remained with no light perception, whereas 6 patients experienced an improvement in visual acuity (2.3 logMAR in 3 patients, 0.7 logMAR in 1 patient, 0.4 logMAR in 1 patient and 0.2 logMAR in 1 patient). These 6 patients had undergone posterior vitrectomy due to vitreoretinal involvement (P<0.001). CONCLUSION: In the case of open globe trauma with no light perception on presentation, a functional recovery is possible if there is no irreversible anatomical damage.

[High plasmatic concentration of vitamin B12: an indicator of hepatic diseases or tumors]. / Concentration plasmatique élevée de la vitamine B12 : un indicateur des maladies hépatiques ou tumorales.

PURPOSE: To identify the diseases that are associated with a high plasma concentration of vitamin B12 and to measure the strength of this association. PATIENTS AND METHODS: Retrospective study including all admissions between 1st May, 2005 and 30th April, 2008 in the UMAG pole departments (emergency, internal medicine, acute geriatrics and medical intensive care) with a test for plasma vitamin B12. The association between each of medical information system codes (solid tumors, malignant hematologic process, and renal disease) and a high or low vitamin B12 concentration was measured by odds ratios (OR) from logistic models taking into account repeated admissions, with adjustment for age and the weighted Charlson index. RESULTS: Among 3702 admissions, 12% had a B12 more than 820pg/ml, 10.4% a B12 less than 180pg/ml and 77.6% a normal B12 concentration. After adjustment for age and the weighted Charlson index, high concentration of vitamin B12 was associated with interstitial renal diseases (OR 2.7; 95% CI: [1.7-4.2]), and cirrhosis or hepatitis (OR 4.3; [2.9-6.4]). After additional adjustment for these parameters, it was still associated with tumors (OR 1.8; [1.2-2.6]), malignant hematologic diseases (OR 2.1; [1.3-3.5]), metastasis (OR 2.9; [1.5-5.9]), liver metastasis (OR 6.2; [2.7-14.5]), liver carcinoma (LC) (OR 3.3; [1.1-10.4]), liver tumors other than LC (OR 4.7; [1.2-17.9]) and lymphoma (OR 3.2; [1.6-6.4]) but not with myeloma (OR 1.9; [0.6-1.4]). Low concentration of B12 was associated with myeloma (OR 2.9; [1.3-6.6]). CONCLUSION: Finding a high plasma concentration of vitamin B12 should lead to a systematic search for a hepatic disease or a tumor, and particularly for a hepatic localization of a tumor.

[Accelerated partial breast irradiation for early breast cancer]. / Irradiation partielle accélérée du cancer du sein : aspect théorique.

Hypofractionated and accelerated partial breast irradiation are more and more widely used for early breast cancer. Here, this short communication would expose the role of hypofractionated radiotherapy in adjuvant breast radiotherapy, rational, techniques and indications of accelerated partial breast irradiation.

[What is your diagnosis? Aneurysm of the abdominal aorta destroying the lumbar spine]. / Quel est votre diagnostic?

A 58 year old woman suffering from lumbalgia over 3 years is admitted for bilateral cruralgia. Ten years before, she was treated for cervix carcinoma by hysterectomy, pelvic and lumbo-aortic radiotherapy and chemotherapy. On admission, physical examination reveals L2 level hypoesthesia and abolition of deep tendon reflexes. Plain films and CT scan show a lysis of L3, L4 and L5 vertebral bodies and a cuneiform appearance of vertebral body of L2 due to a large abdominal aortic aneurysm.
