„Gesundheit“ im Studiengang „Pflege und Gesundheit“ an der FH Hamburg - Profil- und Bedarfsschätzung

At the Fachhochschule Hamburg, a new curriculum on ‘nursing and health’ will be started in summer 1996. This paper informs about ‘health’ in the new curriculum, and the intended emphasis on epidemiology and health promotion. Then the present state of health science instruction in Germany is characterized, and the historical development of interest in this subject. Finally, the short- and long-term need for public health professionals for the north-western part of Germany is estimated.     

Pathophysiological and clinical aspects of the CO2 pneumoperitoneum (CO2-PP)

Experimental studies demonstrated a severe cardiac load of the CO₂ pneumoperitoneum caused by an accelerated after- and a decreased preload. Patients displaying cardiovascular risks are therefore often rejected from laparoscopic surgery. Hence, the pathophysiological changes and the intraoperative risk of the CO₂ pneumoperitoneum in high-risk cardiopulmonary patients (NYHA II–III, n= 15) undergoing laparoscopic cholecystectomy are described. The changes in cardiac after- and preload seem to be due to the elevated intraabdominal pressure rather than transperitoneally resorbed CO₂ and are reversible by desufflation. In one patient conversion to open operation had to be performed because of a severe drop in cardiac output and right ventricle ejection fraction. Mixed oxygen saturation was predicting intraoperative worsening in this case. The described pathophysiological changes may seem to be well tolerated even in high-risk cardiac patients. Monitoring of hemodynamics should include an arterial catheter line and blood gas analyses. Pharmacologic interventions or pressureless laparoscopic procedures might not be necessary as long as laparoscopic cholecystectomy is performed.

Quantitative autoradiography of 11 different transmitter binding sites in the basal forebrain region of the rat--evidence of heterogeneity in distribution patterns.

The distribution of 12 different binding sites for acetylcholine, L-glutamate, GABA, 5-hydroxytryptamine, dopamine and noradrenaline was measured with quantitative receptor autoradiography in four regions of the rat basal forebrain (medial septal nucleus including vertical and horizontal limbs of the diagonal band of Broca, magnocellular preoptic nucleus, substantia innominata and basal nucleus of Meynert, ventral pallidum). L-Glutamate binding sites represent the largest portion of the analysed receptors in all regions, followed by muscarinic2, 5-hydroxytryptamine1 and GABAA receptors. Muscarinic1, dopamine1, dopamine2 and 5-hydroxytryptamine2 receptors and alpha 1-, alpha 1A- and alpha 1B-adrenoceptors represent the minor receptor populations. The largest portion of the dopamine receptors is represented by the dopamine1 subtype, and the alpha 1B subtype dominates the alpha 1-adrenoceptor group. A heterogeneity of the distribution patterns of the different receptors throughout the basal forebrain regions is found. A comparison of the patterns shows that alpha 1-adrenoceptors have a similar regional distribution to that of the muscarinic2 receptors, but both receptor types have reciprocal distributions compared with the 5-hydroxytryptamine1 receptors. The results indicate that one transmitter may exert different effects in the basal forebrain regions depending on the densities of the respective receptor subtypes. Moreover, similar or reciprocal distribution patterns of some, but not all, analysed receptors point to a non-random association (co-distribution) of the different transmitter systems in the basal forebrain regions.     

Growth hormone specific stimulation of mitosis by size-fractionated serum from patients with growth hormone insufficiency: a study on the rat lymphoma cell line, Nb2

The aim was to investigate the bioactivity of a high-molecular weight human growth hormone, identified following molecular sieve chromatography of serum. Nine patients with pituitary disease and GH insufficiency were studied. All patients had non-detectable levels of immunoreactive GH, less than 0.2 micrograms/l, in diurnal serum profiles. GH bioactivity was determined before and after size-fractionation of serum. The bioassay is based on the finding that a rat lymphoma cell line, Nb2, proliferates in the presence of lactogens. GH and PRL immunoreactivities were measured by radioimmunoassays. Pronounced GH immunoreactivity was found in fractions of sera from 7 out of the 9 patients and of 2 of 4 control sera, particularly in fractions corresponding to the elution volume of high-molecular weight proteins (greater than 160 kD). PRL immunoreactivity was only detected in fractions corresponding to the elution volume of monomeric PRL. Unfractionated serum had a dose-dependent mitogenic effect on the Nb2 cells. GH-antibodies could not inhibit this effect. Fractions of serum obtained from the patients stimulated Nb2 cell division as well. The mitogenic effect of serum fractions could be inhibited by GH-antibodies. Thus, high-molecular weight GH circulating in patients with GH insufficiency were shown to exert a GH-specific bioactivity in vitro after size-fractionation.     

Toxicological investigations in the semiconductor industry: I. Studies on the acute oral toxicity of a complex mixture of waste products from the aluminium plasma etching process.

In dry etching processes--one of the sources of potential exposure to toxic wastes in the semiconductor industry--complex mixtures of inorganic and organic compounds arise from reactions between feed stock gases (BCl3/Cl2), top layers (aluminium photoresist), and the carrier gas (N2). Two different fractions of the complex mixture--one an ethanolic solution (ES) and the other an insoluble liquid residue (LR)--were examined for acute oral toxicity in rats. Analytical data showed that the ethanol soluble fraction contained mainly inorganic compounds, whereas the residue contained various halogenated hydrocarbons. Neither death nor behavioral changes occurred after oral administration and observation up to 23 days. ES caused a lower mean arterial blood pressure in both sexes, increased P-R-intervals in male rats, and caused some mild biochemical and hematological alterations and changes in relative organ weights compared to the control groups. Exposure to LR influenced food and water intake, and caused a significant decrease in body weights, signs of polyurie, as well as changes in various relative organ weights and biochemical and hematological parameters. The blood pressure of the male animals fell and the heart rates of both sexes decreased.     

Non-Hodgkin's lymphoma: a differential diagnosis of otogenic facial paralysis

Of all the neoplastic conditions of the lymphatic system, Non-Hodgkin's lymphoma (NHL) represents a heterogenous group. As well as lymph nodes NHL can involve extranodal sites, including regions in head and neck. The mouth and oropharynx are typical extranodal sites, and the ENT surgeon should be aware of this possibility of the swift diagnosis of NHL is to be made. We report two patients with rare invasion of the middle ear, facial nerve paresis, and asymptomatic cerebral involvement by Non-Hodgkin's lymphoma.     

医疗的经济辐射作用

挪威是一个实行市场经济的国家,我们选择了这样的体系是因为它能够有效地解决很多——但不是全部——生产、货物流通以及服务的竞争问题。在发展一个国际化的市场体系的同时,挪威也发展了强大的公共机构和公共服务。一个有效的市场并不意味着我们就不需要公共部门,或者像有些流行观念所认为的,任何公共服务都应该私有化。其实,一个市场是需要严格的监管,需要与公共组织相配合才能良好地运转,而且需要一个广泛覆盖并且有效的公共部门,来补充提供那些市场无法有效而让人满意地提供的服务,比如教育、医疗和环境保护等。但是,这些公共服务不能由…     

Extent of ictal origin in mesial temporal sclerosis patients monitored with subdural intracranial electrodes predicts outcome.

In patients with mesiotemporal sclerosis, posterior hippocampal involvement at the ictal onset is not associated with an excellent outcome. A study confirmed that ictal onset in the posterior parahippocampal gyrus is associated with a less favorable outcome compared with ictal onset in the anterior parahippocampal gyrus in patients with mesiobasal temporal lobe epilepsy who are undergoing foramen ovale recording. The authors hypothesized that involvement of the two medial contact points of posterior basal temporal subdural (SD) strip at the ictal onset, representing ictal onset in the posterior parahippocampal gyrus, may also adversely influence the surgical outcome. With this objective, the authors assessed the incidence of posterior basal temporal SD strip (the two medial contact points) involvement at the ictal onset in patients with mesiotemporal sclerosis and determined whether presence of this finding influenced surgical outcome. Thirty-six patients with mesiotemporal sclerosis underwent a single SD grid (lateral frontotemporal) and strips (three basal temporal and one orbitosubfrontal) monitoring. Based on the earliest involvement of basal temporal strips (the two medial contact points) during the seizure, patients were classified into (1) anterior and/or middle basal temporal, or (2) posterior basal temporal (with or without involvement of anterior and/or middle basal temporal) ictal onset groups. A temporal lobectomy with adequate resection of the ictal onset zone was performed in all patients. Surgical outcome was based on Engel's classification. Six of 36 (17%) patients were classified into the posterior basal temporal ictal onset group. Only two patients from the posterior basal temporal ictal onset group experienced a good outcome compared with 26 of 30 patients from anterior and/or middle basal temporal ictal onset group (P = 0.01). In patients with mesiotemporal sclerosis who were monitored with SD electrodes, involvement of the two medial contact points of posterior basal temporal strip at the ictal onset (representing ictal onset in the posterior parahippocampal gyrus) occurred in 17% of the patients. These patients might not experience an excellent surgical outcome despite including the ictal onset zone in resection. These findings may be useful in presurgical counseling of patients with mesiotemporal sclerosis who undergo intracranial SD monitoring.
