Syphilis and cirrhosis: a lethal combination in a XIX century individual identified from the Medical Schools Collection at the University of Coimbra (Portugal)

Syphilis is a chronic infection that is categorized by a three-stage progression. The tertiary stage may affect bones and produce distinctive skull lesions called caries sicca. This paper aims to present an unusual case of syphilis associated with a diagnosis of cirrhosis, which was recorded as the cause of death in a 28-year-old female in 1899. The appearance and distribution of the lesions were compatible with acquired syphilis, as observed in the skull from the Medical Schools Collection of the University of Coimbra. However, the cause of death was recorded as "hypertrophic cirrhosis of the liver", this is a condition that is compatible with several liver disorders, including a primary liver disorder, such as cirrhosis provoked by alcoholism, infection of the liver by syphilis pathogens or by damage to the liver from the use of mercury compounds, which was the common treatment for syphilis at the time. This paper represents a contribution to the understanding of the natural evolution of syphilis.

Intra-individual variation in body temperature and pectoral muscle size in nestling Alpine swifts Apus melba in response to an episode of inclement weather

The Alpine swift (Apus melba) forages on insects caught exclusively on the wing, implying that dependent nestlings face acute food shortage in periods of cold and rainy weather. Therefore, there should be strong selection on nestling swifts to evolve physiological strategies to cope with periods of undernutrition. We have investigated intra-individual changes in nestling pectoral muscle and body temperature in response to a 1-week period of inclement weather. The pectoral muscle is the largest reserves of proteins, and nestlings have to devote a large amount of energy in the maintenance of body temperature. The results show that nestling pectoral muscle size and body temperature were significantly reduced during the episode of inclement weather. Assuming that these physiological changes are adaptive, our study suggests that nestling swifts spare energy by a pronounced reduction (up to 18 degrees C) in body temperature and use proteins from the pectoral muscle as a source of extra energy to survive prolonged periods of fasting.

Enantiomeric antidepressant drugs should be considered on individual merit

Many antidepressants have been introduced as racemic drugs, the enantiomers of which may differ in some of their pharmacodynamic and pharmacokinetic properties. This review argues that each enantiomer of a chiral antidepressant should be evaluated according to its individual characteristics rather than by extrapolation from the racemate, or by assumptions based on the stereoselective characteristics of other enantiomeric drugs. For example, in some cases the enantiomers' pharmacodynamic and therapeutic properties can be complementary, which suggests that the racemate should be used clinically. In other cases where enantiomers show qualitatively similar but quantitatively different properties to the racemate, using a single enantiomer might be more appropriate. In yet further cases, a distomer may induce the metabolism of the eutomer, enantiomers may be metabolised by different enzymes, there may be a different profile of drug-drug interactions, and therapeutic drug monitoring may be simpler. Therefore, this review exemplifies the principle that each enantiomer of a chiral antidepressant should be evaluated according to its individual pharmacological, pharmacokinetic and pharmacogenetic characteristics. These factors are discussed in relation to five chiral antidepressants: trimipramine, mianserin, mirtazapine, fluoxetine and citalopram. It is hoped that an appreciation of the stereoselective differences between enantiomers will facilitate improvements in the benefit:risk ratio of drugs used in the management of depression.

La construcció del coneixement pràctic. Una anàlisi integrada des dels plans social i individual

La tesi doctoral aborda la relació entre coneixement i pràctica en l’àmbit de la pràctica professional dels mestres. Aquest problema s’aborda des de la psicologia històrico-cultural, la qual implica un trencament amb la “racionalitat tècnica” des de la que s’ha abordat el problema tradicionalment. Aquest nou abordatge de la problemàtica implica una considerable elaboració teòrica, que en la tesi es vehicula mitjançant dos constructes fonamentals: la situació i els conceptes pràctics. Les dades de la tesi consisteixen en les converses face-to-face i on-line entre un estudiant de Mestre en pràcticum i el seu tutor en el centre de pràctiques. L’estudi analitza dos casos d’uns quatre mesos de duració cadascun. L’anàlisi es porta a terme mitjançant anàlisi de discurs, utilitzant diverses unitats d’anàlisi i diverses dimensions, les quals fan possible una anàlisi integrada que permeti considerar de manera relacionada l’activitat conjunta (pla social) i l’ús individual de conceptes (pla individual). Els resultats preliminars suggereixen una especificitat estructural i genètica dels conceptes pràctics (en contrast amb els espontanis i científics), i l’existència de mecanismes d’activitat conjunta que potencien especialment el desenvolupament d’aquests conceptes.
