Driving ability, mental illness and psychotropic medication in the elderly

Fitness to drive in elderly drivers is most commonly discussed with a focus on cognitive impairment. Therefore, this article is focussing on mental illness and the use of psychotropic drugs in elderly drivers, which can both interfere with fitness to drive. Based on a detailed literature review and on clinical judgement, we propose signposts and "red flags" to judge the individual risks. Health professionals dealing with elderly patients should in particular be aware of the dangers related to cumulative risks and need to inform the patients appropriately. For medico-legal reasons the information provided to patients must be written down in the medical record. Individual counselling is important as fitness to drive is a complex topic.

[Atypical case of bronchus carcinoma]

Bronchuscarcinoma ist the most frequent death cause with tumor patients. At time of diagnosis the stadium is often already advanced, the patient is inoperable. We present a patient (non-smoker) with polydipsia, visual troubles and polyuria. The lab results confirmed diabetes insipidus, but the following x-rays proved multiple intracerebral spots. And also multiple spots in the lungs, the mediastinum, in the liver, the coloumn and the adrenals. Histological diagnosis was non small cell lung cancer (NSCLC).

Empfehlungen zur Diagnostik und Therapie der behavioralen und psychologischen Symptome der Demenz (BPSD)

In patients with dementia, Behavioral and Psychological Symptoms of Dementia (BPSD) are frequent findings that accompany deficits caused by cognitive impairment and thus complicate diagnostics, therapy and care. BPSD are a burden both for affected individuals as well as care-givers, and represent a significant challenge for therapy of a patient population with high degree of multi-morbidity. The goal of this therapy-guideline issued by swiss professional associations is to present guidance regarding therapy of BPSD as attendant symptoms in dementia, based on evidence as well as clinical experience. Here it appears to be of particular importance to take into account professional experience, as at this point for most therapeutic options no sufficiently controlled clinical trials are available. A critical discussion of pharmaco-therapeutic intervention is necessary, as this patient-population is particularly vulnerable for medication side-effects. Finally, a particular emphasis is placed on incorporating and systematically reporting psycho-social and nursing options therapeutic intervention.

Aggression und soziale Interaktion im Erziehungsheim

In einer Kamerabrillenstudie werden die sozialen und materiellen Umwelten von Jugendlichen, die in Erziehungsheimen für verhaltensauffällige und sozial beeinträchtigte Kinder und Jugendliche leben, untersucht und mit einer Kontrastgruppe nicht verhaltensauffälliger, zuhause lebender Jugendlichen verglichen. Die Ergebnisse deuten darauf hin, dass Heimjugendliche über einen eingeschränkten Streifraum verfügen, weniger mit Peers interagieren und mehr Aggression ausgesetzt sind. Für den Erfolg der Heimerziehung ist es zentral, Peers nicht unbeaufsichtigt zu lassen, weil durch eine negative Peerbeeinflussung der Erfolg der Intervention geschwächt wird.

Psychothérapie de la dépression chronique : l’apport du modèle CBASP selon McCullough

Les dépressions chroniques sont fréquentes et souvent traitées par des approches traditionnelles. Cet article vise à présenter la nature spécifique de la psychopathologie et un traitement spécifiquement adapté à ces patients avec dépression chronique. Nous décrirons d’abord les spécificités psychopathologiques de cette population, en nous référant aux travaux de J. Piaget et de D. Kiesler. À partir de ces théories, nous mettrons en avant le modèle Cognitive Behavioral Analysis System of Psychotherapy (CBASP), selon McCullough. Cet auteur propose deux volets d’interventions spécifiquement adaptées aux patients avec dépression chronique : l’analyse situationnelle et les techniques interpersonnelles basées sur la notion de transfert et de contre-transfert. Nous soulignerons la pertinence de cette approche par le résumé de plusieurs études empiriques ayant établi l’efficacité de ce modèle, sous certaines conditions cliniques. Nous terminerons par une réflexion de l’application de ce modèle au-delà du tableau clinique de la dépression chronique en ajoutant ainsi des arguments supplémentaires en faveur de l’apport du modèle CBASP au champ actuel de la psychothérapie des troubles mentaux.

Steroidogenesis of the testis - new genes and pathways

Defects of androgen biosynthesis cause 46,XY disorder of sexual development (DSD). All steroids are produced from cholesterol and the early steps of steroidogenesis are common to mineralocorticoid, glucocorticoid and sex steroid production. Genetic mutations in enzymes and proteins supporting the early biosynthesis pathways cause adrenal insufficiency (AI), DSD and gonadal insufficiency. The classic androgen biosynthesis defects with AI are lipoid CAH, CYP11A1 and HSD3B2 deficiencies. Deficiency of CYP17A1 rarely causes AI, and HSD17B3 or SRD5A2 deficiencies only cause 46,XY DSD and gonadal insufficiency. All androgen biosynthesis depends on 17,20 lyase activity of CYP17A1 which is supported by P450 oxidoreductase (POR) and cytochrome b5 (CYB5). Therefore 46,XY DSD with apparent 17,20 lyase deficiency may be due to mutations in CYP17A1, POR or CYB5. Illustrated by patients harboring mutations in SRD5A2, normal development of the male external genitalia depends largely on dihydrotestosterone (DHT) which is converted from circulating testicular testosterone (T) through SRD5A2 in the genital skin. In the classic androgen biosynthetic pathway, T is produced from DHEA and androstenedione/-diol in the testis. However, recently found mutations in AKR1C2/4 genes in undervirilized 46,XY individuals have established a role for a novel, alternative, backdoor pathway for fetal testicular DHT synthesis. In this pathway, which has been first elucidated for the tammar wallaby pouch young, 17-hydroxyprogesterone is converted directly to DHT by 5α-3α reductive steps without going through the androgens of the classic pathway. Enzymes AKR1C2/4 catalyse the critical 3αHSD reductive reaction which feeds 17OH-DHP into the backdoor pathway. In conclusion, androgen production in the fetal testis seems to utilize two pathways but their exact interplay remains to be elucidated.

Widows may have fewer social and financial problems than in the past (Interview von Shereen Lehman mit Prof. Pasqualina Perrig-Chiello zu finanziellen und sozialen Problemen von Verwitweten)

(Reuters Health) – - A new Swiss study says that widows and widowers still mourn their spouses as much as ever, but compared to 35 years ago, everyday life is easier, especially for women. Widows, at least in Switzerland, have fewer financial troubles and more social connections than their counterparts in 1979, but widowers still complain of loneliness, researchers found.

La duchesse d'Enville à Genève, une aristocrate chez les Républicains

Admiratrice de Tronchin, la duchesse d'Enville se rend plusieurs fois à Genève pour de longs séjours. Elle y fréquente toute la bonne société. Et manifestement, elle y apprend à s'intéresser à la politique, à cause des troubles de la cité, qu'elle observe en personne en 1765-1766 et, par l'intermédiaire de ses amis genevois, au début des années 1780. Cette expérience lui a-t-elle servi au début de la révolution française, à l'époque où son salon sert de lieu de rivalité aux Jacobins ?
