Indications à la coronarographie en urgence. Partie II: syndromes coronariens aigus sans élévation du segment ST [Indications for urgent coronary angiography. Part II: Acute coronary syndromes without ST-segment elevation]

The optimal treatment strategy for patients presenting with an acute coronary syndrome without ST elevation is controversial and different therapeutic approaches are recognized. Currently, given the literature available, it is not possible to recommend a universal systematic invasive approach. It is essential to individually risk stratify patients in order to identify those high risk patients that have been shown to benefit from an invasive strategy. Compared to conservative medical treatment, patients at low risk have not been shown to benefit from an invasive strategy. Urgent coronary angiography remains recommended for those patients with persistent or recurrent ischemic symptoms under optimal medical treatment.

Aliments et boissons allégés: qu'en penser [Light food and beverages: what to think about?].

Light food and beverages are increasing on the market for many years, first for economic reasons and, more and more for aesthetisme, however without aimed a defined population. The interest of these products is not evident, reason why it is difficult to get a clear and objective opinion without being influenced by marketing messages. Under what circumstances can they be a solution? Can we advise them? Do they have an influence in the loss or weight control? This article offers some thoughts and suggestions on the use of these specific products.

Antigène carcino-embryonnaire circulant, fortement élevé et persistant, sans cancer décelable

A markedly elevated circulating CEA level was observed in January 1978 in a 40-year-old male patient who complained of functional digestive disorders consisting of 2-3 bowel movements at the end of each night. During follow-up of more than 3 years the CEA level was always found to be higher than 300 ng/ml as determined on 12 different blood samples using 3 different assays: the Hansen assay, our own inhibition radioimmunoassay performed on perchloric acid extract of serum, and a newly developed solid phase non-competitive enzyme immunoassay involving monoclonal anti-CEA antibody. The clinical evolution showed no aggravation of the persistent but mild bowel troubles, i.e. no real diarrhea or blood in the stool. The patient enjoys excellent general health and shows no weight loss. Barium enema, colonoscopy and extensive investigation by computerized axial tomography showed no evidence of primary or metastatic tumor. Apart from CEA, the blood chemistry was within normal limits. Six members of the patient's family have normal CEA levels. A possible explanation for this unique case of marked and persistent elevation of circulating CEA without evidence of cancer is discussed.

Lésions cutanées et infiltrats pulmonaires d'évolution défavorable sans cause infectieuse [Progressive cutaneous and pulmonary lesions without infectious etiology: two cases reports of sweet syndrome with pulmonary involvement].

Sweet syndrome is a non infectious febrile disease with a neutrophilic infiltrate of dermis. Extracutaneous involvement can occur. We report two cases of Sweet syndrome with cutaneous and pulmonary involvement and give a short review of the literature of pulmonary involvement in Sweet syndrome.

Résultats anatomiques comparés à long terme de décollements de rétine avec prolifération vitréo-rétinienne opérés avec ou sans utilisation de perfluorocarbones liquides [Long-term comparative anatomic results of retinal detachment with vitreoretinal proliferation operated with or without using liquid perfluorocarbons].

PURPOSE: To investigate whether peroperative perfluorocarbon liquids (PFCL) improve the long term anatomical success of retinal detachment associated with severe proliferative vitreoretinopathy (PVR). PATIENTS AND METHODS: The charts of 62 successive patients operated on for retinal detachment associated with severe PVR were retrospectively analyzed. For one group of 39 patients PFCL were used intraoperatively to improve membrane dissection. The anatomical status of the two groups were compared one month after surgery and at least 6 months after silicone oil ablation. RESULTS: Anatomical success was observed in 84.6% in the group of patients operated with PFCL compared to 52% in the other group (P = 0.005). At the end of the follow up, anatomical success was observed in 64% of patients operated with PFCL compared to 61% in the control group (P = 0.8). However, recurrences were observed later in the group operated on with PFCL. CONCLUSION: Perfluorocarbons liquids significantly improve the initial reattachment of retinal detachment complicated with severe PVR, but they do not seem to improve their final anatomical status.

Carence en fer sans anémie: où en est-on en 2012 [Iron deficiency without anemia: where are we in 2012?].

Should we treat iron deficiency without anemia? The simple fact that the question can be formulated already leads to controversies. During the past years, the development of a new formulation of intravenous iron has helped fuel the controversy. What is the situation in 2012? This article gives a practical point of view on the actual situation and provides indications on the use of new intravenous medications.
