Medizinische Beurteilungskriterien zu bandscheibenbedingten Berufskrankheiten der Lendenwirbelsäule (I)

Occupational diseases Nos. 2108 and 2110 correspond to intervertebral disc-related diseases of the lumbar spine from many years of carrying or lifting heavy loads, occupations in extreme postures of full flexion or oscillation of the whole body when seated, and which compel the cessation of all activities which are or could be the cause for the origin, exacerbation or recurrence of the disease. These occupational diseases came into force at the start of 1993, but there have been considerable problems in their implementation. The present Part I of the contribution is the result of the work of an interdisciplinary study group and contains medical criteria for the assessment of possibly strain-related clinical characteristics and the evaluation of other possible causes. Part II is to be published in Volume 4/2005 and will deal with questions related to forced cessation and to the assessment of the loss of earning ability. Agreement was reached in many areas related to the assessment of occupational claims. This should allow for evidence-based decision making in the future for the occupational diseases Nos. 2108 and 2110.     

European view toward incorporating adverse events into package inserts.

The information contained in package inserts varies from country to country in Europe, although other regulatory aspects of data presentation are quite similar. West Germany's Drug Law of 1976 requires 11 items to be included in the package insert for both patient and health professional: name/address of manufacturer; drug name; active constituents; indications; contraindications; side effects; drug interactions; dosage instructions; method and duration of application; statement that drug should not be used after expiration date; and statement that drug should be kept out of reach of children. All information must be submitted to the Health Office at the time of application or the applicant is liable for criminal prosecution. Documentation of side effects must be complete, although no special form is required. Similarly, causality assessment needs to be made even though specific algorithms are not required. Proposed amendments to the Drug Law will include additional information to physicians concerning the overdose instructions, pharmacological properties, and bioavailability of the drug. Registration procedures are the same throughout Europe and are called Summary of Products Characteristics. Assessment reports are also required for each new chemical entity in the European Community.     

Repeated measurements of mite and pet allergen levels in house dust over a time period of 8 years

BACKGROUND: Studies of the association between indoor allergen exposure and the development of allergic diseases have often measured allergen exposure at one point in time. OBJECTIVE: We investigated the variability of house dust mite (Der p 1, Der f 1) and cat (Fel d 1) allergen in Dutch homes over a period of 8 years. METHODS: Data were obtained in the Dutch PIAMA birth cohort study. Dust from the child's mattress, the parents' mattress and the living room floor was collected at four points in time, when the child was 3 months, 4, 6 and 8 years old. Dust samples were analysed for Der p 1, Der f 1 and Fel d 1 by sandwich enzyme immuno assay. RESULTS: Mite allergen concentrations for the child's mattress, the parents' mattress and the living room floor were moderately correlated between time-points. Agreement was better for cat allergen. For Der p 1 and Der f 1 on the child's mattress, the within-home variance was close to or smaller than the between-home variance in most cases. For Fel d 1, the within-home variance was almost always smaller than the between-home variance. Results were similar for allergen levels expressed per gram of dust and allergen levels expressed per square metre of the sampled surface. Variance ratios were smaller when samples were taken at shorter time intervals than at longer time intervals. CONCLUSION: Over a period of 4 years, mite and cat allergens measured in house dust are sufficiently stable to use single measurements with confidence in epidemiological studies. The within-home variance was larger when samples were taken 8 years apart so that over such long periods, repetition of sampling is recommended.     

Über Kompression und Narkose

Zusammenfassung Die Arbeit stellt den Begriff der Mechanonarkose auf und setzt Chemonarkose und Mechanonarkose in Parallele zueinander. Sowohl chemische Narkotica wie physikalische Kompression machen reversible Lähmungen und irreversible Schädigungen der verschiedensten tierischen und pflanzlichen Lebenserscheinungen, wobei die Lebewesen oder die Organe eines Lebewesens sich nach ihrer Empfindlichkeit und Resistenz in die gleiche Reihenfolge für beide Agentien anordnen. Beide machen in unternarkotischer Dosis allerlei Reizerscheinungen, in übernarkotischer Dosis an Muskeln Kontraktur und Verkürzung, und sind in ihrer Wirkung bis ins Einzelne vergleichbar. Als gemeinsame Erklärungsmöglichkeit für beide Agentien wird die Viscositätserhöhung an Zellgrenzen und Zelloberflächen mit ihrer Erschwerung von Diffusion und Stoffaustausch (Oberflächenverdichtung, Permeabilitätsabnahme) und ihren weiteren Folgen für den Zellstoffwechsel betrachtet.     

Ethische Aspekte der ästhetischen Medizin

The article examines the question whether and – if – under which conditions physicians should perform purely esthetic interventions. Starting point of the considerations is the special character of the medical profession and the necessity of the anticipated confidence in the system of medicine. The medical measures for aesthetic improvement are systematized. Medical measures to increase the wanted, positively felt attention of others are not compellingly required according to the medical ethic. Nevertheless they do not offend the ethos if high quality standards are insured: The measures must be presumably helpful for the patient; a thorough informed consent and avoidance of damage must be insured. Esthetic measures, in particular operations which are totally cosmetic, should be limited strictly if performed with children and adolescents. Nevertheless convincing arguments support medical-esthetic measures with children and adolescents to avoid stigmatization.
