Paradoxical association between smoking and olfactory identification in psychosis versus controls

Objective: Deficits in olfactory identification have been demonstrated in patients with schizophrenia. This study examined the interaction between smoking and olfactory identification in patients with psychotic disorders versus well controls. Method: Olfactory identification was assessed in three groups of subjects using the University of Pennsylvania Smell Identification Test (UPSIT). Sixteen patients with affective psychoses, 22 patients with nonaffective psychoses, and 21 well controls were tested. Results: There was a significant interaction between diagnostic classification (patient or control) and smoking. Patients who were smokers scored higher on the UPSIT than non-smokers, while controls who were smokers scored lower than non-smokers. Conclusions: Smoking may have a 'normalising' effect on olfactory identification in some patients with psychosis. Further studies are needed to examine the relationship between psychosis, olfactory identification and the effects of nicotine.

Australian norms for a quantitative olfactory function test

Quantitative olfactory assessment is often neglected in clinical practice, although olfactory loss can assist diagnosis and leads to significant morbidity. The aim of this study was to develop normative data for the Australian population for the 'Sniffin' Sticks', an internationally established olfactory function test. As in other populations, Australian females performed better than males and both lost olfactory function with age. From the normative data, criterion test scores for males and females were established for clinical classifications ('normosmic', 'hyposmic', and 'anosmic'). These clinical classifications were assessed in Parkinson's patients: 81.1 % were anosmic or severely hyposmic and only 7.7% were normosmic. A new term ('prebyosmia') is introduced to describe age-related loss of olfactory capacity of unknown aetiology. With these norms, the Sniffin' Sticks can be used in the Australian population to compare an individual's olfactory function against the population of others of similar age and sex and to identify olfactory dysfunction.

The natural jurisprudence of Jean Barbeyrac: translation as an art of political adjustment

The article makes the case for redescribing Jean Barbeyrac [1674-1744], the great French translator and influential glossator of seventeenth-century Latin natural-law texts, as something quite other than a neutral mediator of Samuel Pufendorf. To consider the specific religious and political charge of his strategies as translator is to recognize the independence of Barbeyrac's Huguenot stance on natura; jurisprudence. This stance is provoked by the profound challenge that Pufendorf's radical post-Wespthalian secularizing of civil authority posed for a Huguenot: how to grant that the state had legitimate authority to regulate all external conduct, but at the same time preserve an inviolable moral space for the exercise of individual conscience. The argument--pointing to Barbeyrac's construction of a 'Lockeanized' Pufendorf--rests both on his famous presentation of Leibniz's critique of Pufendorf's De officio hominis et civis and on more neglected elements of Barbeyrac's corpus.
