Poison without antidote for the historical Socrates and french classical tragedy in El verí del teatre (The Poison of the Theatre) by Rodolf Sirera. (An extreme dose of sadism to put a stop to the excesses of theatrical fiction).

Socrates' serene attitude before his death -although this is questioned-, as described by Xenophon in his Apologia Socratis becomes for the playwright Rodolf Sirera a useful reference in an effort to reflect boldly on the limits of theatrical fiction in another clear example of the Classical Tradition, including that derived from Baroque Tragedy. However, in this case, it is judged severely to make us more conscious of the risk of turning life into a mere theatrical performance and human beings into actors and actresses in a play they did not write.

High-dose therapy and autologous hematopoietic stem cell transplantation in T-cell lymphoma : a single centre experience

Le diagnostic de lymphome représente 4% de tous les cancers et a une incidence particulièrement élevée dans les pays industrialisés. La proportion de lymphomes T, évaluée en Europe et aux Etats Unis, représente environ 5 à 10% des lymphomes. Alors que des progrès très sensibles ont été apportés dans la prise en charge et le pronostic des lymphomes B agressifs durant ces dernières décennies et en particulier depuis le début des années 2000 avec l'utilisation des anticorps anti-CD20 associés à la chimiothérapie, le pronostic des lymphomes T reste très décevant. La survie globale des lymphomes T à 5 ans est estimée entre 28% et 38%. Le bénéfice réel d'une chimiothérapie intensive suivie d'une autogreffe de cellules souches hématopoïétiques périphériques au terme d'un traitement de chimiothérapie d'induction dans le lymphome T périphérique reste débattu. Les résultats des rares études prospectives et des études rétrospectives à disposition sont discordants. Nous avons donc analysé rétrospectivement 43 patients successifs de mars 2000 à mars 2011, atteints de lymphome T, issus de notre base de données du programme autogreffe lausannois. Nos analyses statistiques permettent, sur la base d'un suivi médian de 63 mois, une estimation à 12 ans, de la survie globale de nos patients à 40%, de la survie sans progression à 34% et de la survie sans événement à 30%. Ces chiffres s'inscrivent parfaitement dans les résultats des études prospectives qui montrent un bénéfice de l'autogreffe dans le lymphome T. Parmi les différents paramètres pronostiques habituellement évalués, l'âge et l'absence de symptômes B au diagnostic sont les seuls paramètres statistiquement significatifs en analyse univariée dans notre cohorte. En effet, Les patients de moins de 50 ans et ceux qui ne présentent pas de symptômes B au diagnostic ont un meilleur pronostic. Nous concluons de cette analyse que les patients traités par chimiothérapie intensive et autogreffe de cellules souches hématopoïétiques périphériques ont une survie moyenne supérieure aux résultats rapportés dans la littérature avec des traitements de chimiothérapie conventionnelle de type CHOP. En effet, on estime à environ 50% les patients répondant à une chimiothérapie conventionnelle de type CHOP.

Treating the individual hypertensive patient: considerations on dose, sequential monotherapy and drug combinations.

For the general practitioner to be able to prescribe optimal therapy to his individual hypertensive patients, he needs accurate information on the therapeutic agents he is going to administer and practical treatment strategies. The information on drugs and drug combinations has to be applicable to the treatment of individual patients and not just patient study groups. A basic requirement is knowledge of the dose-response relationship for each compound in order to choose the optimal therapeutic dose. Contrary to general assumption, this key information is difficult to obtain and often not available to the physician for many years after marketing of a drug. As a consequence, excessive doses are often used. Furthermore, the physician needs comparative data on the various antihypertensive drugs that are applicable to the treatment of individual patients. In order to minimize potential side effects due to unnecessary combinations of compounds, the strategy of sequential monotherapy is proposed, with the goal of treating as many patients as possible with monotherapy at optimal doses. More drug trials of a crossover design and more individualized analyses of the results are badly needed to provide the physician with information that he can use in his daily practice. In this time of continuous intensive development of new antihypertensive agents, much could be gained in enhanced efficacy and reduced incidence of side effects by taking a closer look at the drugs already available and using them more appropriately in individual patients.

Dose-dependent effect of atrial natriuretic peptide on blood pressure, heart rate, and skin blood flow of normal volunteers.

Synthetic atrial natriuretic peptide, containing 26 amino acids in the rat sequence, L-364, 343 (Ileu-ANP), was infused intravenously at increasing rates (1-40 micrograms/min) into four normal volunteers. Mean intraarterial blood pressure decreased and heart rate increased in cumulative-dose-dependent fashion. Skin blood flow as measured with a laser Doppler device rose already with a cumulative dose of 55 micrograms Ileu-ANP and further rises were directly related to dose. The only side effects observed were those accompanying symptomatic hypotension at higher doses. These findings provide strong evidence that Ileu-ANP acts as a vasodilator in normal volunteers.

Screening of illegal intracorporeal containers ("body packing"): is abdominal radiography sufficiently accurate? A comparative study with low-dose CT.

PURPOSE: To evaluate the diagnostic performance of abdominal radiography in the detection of illegal intracorporeal containers (hereafter, packets), with low-dose computed tomography (CT) as the reference standard. MATERIALS AND METHODS: This study was approved by the institutional ethical review board, with written informed consent. From July 2007 to July 2010, 330 people (296 men, 34 women; mean age, 32 years [range, 18-55 years]) suspected of having ingested drug packets underwent supine abdominal radiography and low-dose CT. The presence or absence of packets at abdominal radiography was reported, with low-dose CT as the reference standard. The density and number of packets (≤ 12 or >12) at low-dose CT were recorded and analyzed to determine whether those variables influence interpretation of results at abdominal radiography. RESULTS: Packets were detected at low-dose CT in 53 (16%) suspects. Sensitivity of abdominal radiography for depiction of packets was 0.77 (41 of 53), and specificity was 0.96 (267 of 277). The packets appeared isoattenuated to the bowel contents at low-dose CT in 16 (30%) of the 53 suspects with positive results. Nineteen (36%) of the 53 suspects with positive low-dose CT results had fewer than 12 packets. Packets that were isoattenuated at low-dose CT and a low number of packets (≤12) were both significantly associated with false-negative results at abdominal radiography (P = .004 and P = .016, respectively). CONCLUSION: Abdominal radiography is mainly limited by low sensitivity when compared with low-dose CT in the screening of people suspected of carrying drug packets. Low-dose CT is an effective imaging alternative to abdominal radiography.
