[Problem-based learning (POL) in environmental medicine].

"Environmental medicine" is a new sub-discipline in the spectrum of medical specialization in Germany. The Berlin Academy of Occupational Medicine and Health Protection, now a branch of the Berlin Chamber of Physicians, developed a 200-lesson curriculum for physicians who want to specialize in this field. Coincidentally during the initial courses, the attendants were already highly qualified ("Facharzt"-level) and experts in various occupational fields, and hence the composition of the classes was highly heterogeneous on the levels of practical experience as well as theoretical knowledge. The Academy therefore decided to change the teaching method to Problem-Oriented Learning (POL). This required training tutors for small learning groups, supervision for these tutors and supplying adequate teaching materials and a stimulating environment for the student. The "Arbeitsgruppe Reformstudiengang Medizin" (Medicine Curriculum Reform Project) at the Berlin Humboldt University as well as the Dutch Rijksuniversiteit Limburg in Maastricht helped in the process of conceptualization. Participants worked in groups of up to 8 persons under non-directive tutors. A new "case" was presented every day, and the students developed individual learning goals according to the Seven Steps-method, which were then researched individually and with the help of outside experts. The findings were reported back and discussed in the group. Initially there was irritation, but after two or three days participants got used to not being lectured. Instead of being passive recipients of expert knowledge they felt that the POL method of learning enhanced their competence to act independently.

[Initial experiences with the new environmental medicine course in graduate education].

The "master of environmental medicine" is a new medical subspeciality in Germany. Specialised physicians can qualify for it, if they have spent at least an additional period of 1.5 years at a recognized institution in the field. Furthermore the attendance of a 200 hours comprehensive specialist's training course is required. Preliminary experience with this comprehensive course, as offered by our institution (Academy of Occupational and Environmental Medicine, Berlin, Germany) is lined out. Additionally, details of the curriculum, which was specifically designed for this purpose by our institution, are given. The results of an evaluation-procedure (questionnaire) among those participants, who completed the first parts of the course, are discussed.

Advantages and limitations of medical dispatching: the French view.

One of the main features of the French emergency medical services (EMS) system as it has been developed during the last 40 years is the participation of a physician in each stage of the EMS organization. Thus, in the 100 French emergency medical dispatch centres, all calls received on 15, the national medical emergency phone number, are medically dispatched. The main advantages are: (i) better security for the caller; (ii) proper adaptation of the response to the emergency; (iii) a quicker and more efficient intervention time; (iv) the hospital is informed of the arrival of an emergency; (v) the respect of medical secrecy; (vi) a good cost-efficiency ratio in the use of intervention means. The main limitations are connected with: (i) the inaccuracy of certain calls and problems of dialogue with the caller; (ii) the poor acceptance of the system's obligations by some of the callers, patients, physicians or any other partners of the EMS organization. In the future the implementation of the multi-purpose European emergency number 112 will probably require the system's adaptation to it.

Early genetic amniocentesis and chorionic villus sampling. Expanding the opportunities for early prenatal diagnosis.

At centers where chorionic villus sampling (CVS) programs are operational, first-trimester prenatal diagnosis has been shown to have many advantages, both medical and psychologic. However, most medical centers do not have CVS capability, nor are all patients candidates for CVS. We investigated the feasibility of performing very early genetic amniocentesis (9-13 weeks' gestational age). The results from those amniocenteses were compared to our own CVS data. In experienced hands, (1) CVS can be performed safely at 8-13 weeks, with the most technical ease at 9-11 weeks; (2) CVS or amniocentesis can be performed on many patients at 12-13 weeks or perhaps even earlier, although no accurate loss rates are available yet; (3) when technically feasible, CVS may be advantageous because of the much faster time period for cytogenetic results from direct preparation or short-term culture; and (4) in those patients on whom CVS cannot be performed, early amniocentesis in selected patients may offer the benefits of early diagnosis.

Karyotypic polymorphism in acute myelofibrosis.

Acute myelofibrosis (AMF) was diagnosed in a 59-yr-old black male in September 1978, on the basis of pancytopenia, lack of hepatosplenomegaly, fibrosis of the marrow, and paucity of teardrop red blood cells in the peripheral blood. Since then the patient has demonstrated an unusually long survival of 36 mo with a changing cytogenetic course. His initial 46, XY normal karyotype changed in 20 mo to trisomy 8, followed 1 yr later by 1:4 translocation in peripheral blood. Simultaneously with these changes, the fibrosis in the bone marrow progressively decreased, ultimately terminating in chronic granulocytic leukemia-like presentation with reversal to 46, XY karyotype. Fibroblast culture failed to show any evidence of cytogenetic abnormalities. The disappearance of fibrosis confirmed by trichrome and reticulin stains and lack of cytogenetic abnormalities in fibroblasts confirms the secondary role of fibrosis.

[Determination of alphaxalone in serum and urine by gas-liquid chromatography. Application in anaesthesiological pharmacology (author's transl)].

The authors propose a simple and reliable method for determination of alphaxalone [3 alpha-hydroxy(5 alpha)pregnane 11,20 dione] in serum and urine, during long-duration anaesthesia using Althesin, mixture of alphaxalone and alphadolone acetate [21 acetoxy, 3 alpha-hydroxy(5 alpha)pregnane 11,20 dione]. If assays of alphadolone appear difficult and without any precision, because of numerous interferences, the determination of alphaxalone in serum and urine seems interesting for pharmacokinetic and metabolic investigation. We confirm the quick rate of disappearance of alphaxalone from blood, associated with a very active metabolism in the liver. The results show that it exists a relation between the concentration of alphaxalone in blood and the value of anaesthesia judged on clinical and electrical criteria. We cannot however conclude that Althesin presents a cumulative effect, because we used important amounts of anaesthetic agent.

[Problems presented to the surgeon, anesthetist and resuscitation personnel by fractures of the malar bone (study of 100 cases)].

The authors emphasize the difficulties encountered with fractures of the zygomatic bone, both from the technical operative points of view and conditions of anaesthesia and intensive care. They distinguish in both fields, the so-called simple zygomatic fractures from fractures associated with multiple injuries of the face or skull. After recalling the surgical techniques, they consider routine management, from diagnosis to recovery from the anaesthetic, emphasizing the problem of the time of the operation, of the method ensuring freedom of the airways and anaesthetic indications used together with problems of intensive care.

[Organization of first aid on the northern motorway in Picardy. Role of the regional Medical First Aid Unit].

The Picardy regional S.A.M.U. implanted in Amiens, has participated in the implantation of antennae of the S.M.U.R. whereby aid can be given accident cases on the northern motorway. After a brief historical review of the creation of these antennae, and presentation of what exists in the sections of the northern motorway not in Picardy, the means of the regional S.A.M.U. are presented, and the way it which it functions, with regards to specific problems concerning medical aid on the motorway. The results of the S.M.U.R. activities are presented and discussed. The necessity for good coordination of medical aid, the fundamental role of the regional S.A.M.U., is particularly emphasized.

[The advantages and disadvantages of different methods of access to the internal jugular veins (author's transl)].

The authors have made a critical study of the respective advantages and disadvantages of the various methods of access to the internal jugular vein. These have been classified under 3 headings: frontal access, lateral access and rear access. They outline their experience of the technique described by Boulanger and Delva in 1977. This method of access seems to be favoured on two scores, its simplicity and the absence of immediate serious complications. These encouraging results lead them to advocate this as the technique they would choose especially in urgent cases.
