- Endometrial cancer is a disease with serious impact on the human population, but not much is known about genetic factors involved in this complex disease. Female BDII rats are genetically predisposed to spontaneous endometrial carcinoma, and the BDII inbred strain provides an experimental animal model for endometrial carcinoma development. In the present study, BDII females were crossed with males from two nonsusceptible inbred rat strains. Endometrial adenocarcinomas (EACs) developed in a proportion of the F1 and F2 progeny. We screened 18 EAC solid tumors and 9 EAC cell cultures for loss of heterozygosity (LOH) using fluorescent-PCR-based marker allelotyping methodology with 47 microsatellite markers covering the proximal part of rat chromosome 10 (RNO10). Conclusive evidence was obtained for LOH/deletion involving about 56 cM in the proximal part of RNO10 in DNA from six out of seven informative tumor cell cultures. Analysis of the solid tumors confirmed the presence of LOH in this part of RNO10 in 14 of 17 informative tumors. However, from the studies in the solid tumors it appeared that in fact three separate segments in the proximal part of RNO10 were affected. These three LOH/deletion regions were located approximately in cytogenetic bands 10q11-12, 10q22, and 10q24.

- Although pain is a frequent problem among elderly patients, they are often omitted in clinical trials and few studies have focused on assessing pain relief in this population. The aim of this study was to compare geriatric patients' verbally reported effect of analgesics with changes in pain experience rated with four different rating scales: the Visual Analogue Scale (VAS), the Graphic Rating Scale (GRS), the Numeric Rating Scale (NRS), and the Pain Relief Scale (PRS). Altogether 53 geriatric patients (mean=82 yrs) with non-pathological fractures in 4 geriatric units at a large university hospital were selected. In connection with the administration of analgesics, the patients were asked to "Mark the point that corresponds to your experience of pain just now at rest" on the VAS, GRS and NRS. This was repeated after 1.5-2 hours, and a direct question was asked about whether the analgesic medication given in connection with the initial assessment had had any pain-alleviation effect. Two comparisons were conducted with each patient. The results show that the probability of accomplishing a rating on the VAS, GRS, NRS, and PRS was lower with advancing age in these elderly fracture patients. The correlations between the ratings of the VAS, GRS and NRS were strong and significant (r=0.80-0.95; p<0.001) both at the initial assessments and at the re-assessments. However, the verbally reported effects of the analgesics were often directly opposite to the changes in rated pain. Therefore, application of the VAS, NRS, GRS and PRS for the purpose of assessing pain relief must be combined with supplementary questions that allow the patient to verbally describe possible experience of pain relief.

- Patient safety and comfort during general anaesthesia and surgery are to a considerable extent dependent on the capability of anaesthesia personnel to interpret directly monitored as well as indirect clinical signs of pain and/or depth of anaesthesia. The aim of the present study was to evaluate how nurse anaesthetists in their clinical routine work assess and interpret intra-operative responses evoked by pain stimuli and/or insufficient depth of anaesthesia. A questionnaire was designed to assess the perceived relevance and validity of cardiovascular, respiratory, mucocutaneous, eye-associated, and muscular responses for routine assessment of intra-operative pain and/or insufficient depth of anaesthesia in patients undergoing surgery under general anaesthesia. Data were obtained from 223 nurse anaesthetists working at nine different university anaesthesia departments in Sweden. A number of significant indicators for pain and depth of anaesthesia could be identified for spontaneously breathing as well as for mechanically ventilated patients. No variable was considered entirely specific for either intra-operative pain or depth of anaesthesia. Changes in breathing rate/volume, central haemodynamics (BP, HR), lacrimation, and presence of moist and sticky skin were given higher score values as indicators of pain than as indicators of depth of anaesthesia. Occurrence of grimaces, attempted movements, and presence of non-centred pupils were variables considered more indicative of insufficient depth of anaesthesia than intra-operative pain. In conclusion, it is obvious from the present data that indirect physiological signs of intra-operative pain and depth of anaesthesia are still considered of importance by Swedish anaesthesia nurses in the anaesthetic management of surgical patients.
