Surgical outcomes of deep sclerectomy versus Baerveldt aqueous shunt implantation following initial failed deep sclerectomy

Purpose: To examine the efficacy and safety of repeat deep sclerectomy (DS) versus Baerveldt shunt (BS) implantation as second line surgery following failed primary DS. Methods: Fifty one patients were prospectively recruited to undergo BS implantation following failed DS and 51 patients underwent repeat DS, for which data was collected retrospectively. All eyes had at least one failed DS. Surgical success was defined as IOP≤21mmHg and 20% reduction in IOP from baseline. Success rates, number of glaucoma medications (GMs), IOP, and complication rates were compared between the two groups at year 1, post-operatively. Results: Mean age, sex and the proportion of glaucoma subtypes were similar between groups. Preoperatively IOP was significantly lower in DS group vs BS group (18.8mmHg vs 23.8mmHg, p<0.01, two sample t-test). Postoperatively IOP was significantly higher in DS group than BS group (14.6mmHg vs 12.0mmHg, p<0.01, two-sample t-test). In the DS group, 47% of eyes did not achieve 20% reduction in IOP from baseline, as a result the success rates were significantly lower in eyes with DS (51%) than in eyes with BS (88%) (p=0.02, log-rank test). Preoperatively the number of GMs used in DS and BS groups were similar (2.2 vs 2.7 p=0.02, two sample t-test). Postoperatively there remained no significant difference in GMs between groups (0.9 vs 1.1, p= 0.58, two sample t-test). Complication rates were similar between the two groups (12% vs 10%). Conclusions: Baerveldt tube implantation was more effective in lowering IOP than repeat deep sclerectomy in eyes with failed primary DS, at year one. Complications were minor and infrequent in both groups

Measurement of β-tryptase in postmortem serum, pericardial fluid, urine and vitreous humor in the forensic setting.

In the realm of forensic pathology, β-tryptase measurement for diagnostic purposes is performed in postmortem serum obtained from femoral blood. This may be partially or completely unavailable in some specific cases, such as infant autopsies and severely damaged bodies. The aim of this study was to investigate the usefulness of determining β-tryptase levels for diagnostic purposes in alternative biological samples. Urine, vitreous humor and pericardial fluid were selected and measured in 94 subjects including: fatal anaphylaxis following contrast material administration (6 cases), hypothermia (10 cases), diabetic ketoacidosis (10 cases), gunshot suicide (10 cases), heroin injection-related deaths (18 cases), trauma (10 cases), sudden death with minimal coronary atherosclerosis (10 cases), severe coronary atherosclerosis without myocardial infarction (10 cases) and severe coronary atherosclerosis with myocardial infarction (10 cases). Postmortem serum and pericardial fluid β-tryptase levels higher than the clinical reference value (11.4ng/ml) were systematically identified in fatal anaphylaxis following contrast material administration and 6 cases unrelated to anaphylaxis. β-tryptase concentrations in urine and vitreous humor were lower than the clinical reference value in all cases included in this study. Determination of β-tryptase in pericardial fluid appears to be a possible alternative to postmortem serum in the early postmortem period when femoral blood cannot be collected during autopsy and biochemical investigations are required to objectify increased β-tryptase levels.

El Sentit de l'humor en els infants : una breu aproximació des de la psicologia cognitiva

Darrerament hem investigat l’emergència del metallenguatge en els infants en contextos d’interaccions comunicatives naturals (Ivern, 2006) i hem establert un sistema de categories metalingüístiques per tal d’identifi car i conceptualitzar aquells comportaments relacionats amb la refl exió sobre el llenguatge, tot emmarcat en una perspectiva evolutiva. Els participants han estat 32 infants, 16 nens i 16 nenes, d’edats compreses entre els 2 anys i 8 mesos i els 8 anys, tots ells de parla castellana. Entre altres aspectes hem analitzat les funcions que compleix, atenent especialment a la relació tripartida entre metallenguatge, metacognició i recursivitat. En darrer terme, ens ha semblat interessant analitzar la relació del metallenguatge amb la teoria de la ment i el sentit de l’humor. La naturalesa metalingüística de l’humor ha estat estudiada des de principis dels anys setanta (Shultz, 1974 i Cazden, 1976) fi ns l’actualitat (Puche, 2001; Puche i Lozano, 2002). Bona part de l’nterès que ha desvetllat és per la seva importància com a indicador de l’activitat cognitiva. A continuació exposem una refl exió breu sobre el paper que juga el sentit de l’humor en els infants des de la perspectiva de la psicologia cognitiva.

Postmortem measurement of human chorionic gonadotropin in vitreous humor and bile.

Postmortem human chorionic gonadotrophin (HCG) blood assay can confirm postmortem diagnosis of pregnancy or document situations in which HCG levels are elevated. In some cases, however, blood sampling is not possible at autopsy. In this study, HCG was quantified by enzyme-linked fluorescent assay (ELFA) in the bile (n = 5), vitreous humor (n = 4), and postmortem blood (n = 4) of five pregnant women. There were no false negatives in the pregnant subjects (n = 5) or false positives in controls (n = 34), enabling this test to be recommended for routine use in forensic contexts in which the detection of elevated HCG levels could be of interest.

El sentit de l'humor més agut s'amaga al cervell

El humor como trampantojo en el teatro de Miguel Mihura

Tras el humor de las comedias de Mihura hay una crítica a las normas que rigen la vida de las personas. Con el sutil juego literario, lleno de ingenio y humor, Miguel Mihura pone de manifiesto lo inamovibles que son los convencionalismos que condicionan nuestra existencia y en los que basamos a menudo nuestros juicios.

Humor en majúscules

Aquestes dies s'ha parlat molt de l'humor, en el context de la llibertat d'expressió i de si hauríem, o no, en democràcia, d'autoimposar-nos límits. Som l'única espècie que té sentit de l'humor, i l'utilitzem de forma habitual en les nostres interaccions socials. L'humor té un lloc especial al nostre cervell, i l'estudi del seu funcionament aporta dades que ens permeten aprofundir en el concepte més ampli d'humanitat.

Mediarte com Amor e Humor: uma Experiência a partir do Olhar dos Participantes

Trata-se de um relato e reflexão a respeito do Projeto MediArte com Amor e Humor, com base nas vivências e percepções das autoras/estudantes integrantes do projeto. O Projeto é uma atividade de extensão da UFRN envolvendo estudantes de medicina. Neste objetiva-se trabalhar a humanização por meio das virtudes humor e amor através de atividades lúdico-recreativas, nas dependências do Hospital de Pediatria da UFRN, envolvendo pacientes, acompanhantes e profissionais semelhantes às intervenções de palhaçoterapia. Busca-se, dentre outros aspectos, resgatar o sorriso e alegria das crianças doentes e promover o cuidado humanizado. Observa-se que a presente iniciativa conforma-se como uma estratégia de educar em saúde, onde teoria e práticas potencialmente interdisciplinares, humanizadoras e éticas são desenvolvidas, contribuindo para uma formação mais integral dos alunos de graduação, bem como uma iniciativa de humanização do cuidado no SUS.
