Normal oral, rectal, tympanic and axillary body temperature in adult men and women: a systematic literature review The purpose of this study was to investigate normal body temperature in adult men and women. A systematic review of data was performed. Searches were carried out in MEDLINE, CINAHL, and manually from identified articles reference lists. Studies from 1935 to 1999 were included. Articles were classified as (1) strong, (2) fairly strong and (3) weak evidence. When summarizing studies with strong or fairly strong evidence the range for oral temperature was 33.2–38.2 °C, rectal: 34.4–37.8 °C, tympanic: 35.4– 37.8 °C and axillary: 35.5–37.0 °C. The range in oral temperature for men and women, respectively, was 35.7–37.7 and 33.2–38.1 °C, in rectal 36.7–37.5 and 36.8–37.1 °C, and in tympanic 35.5–37.5 and 35.7–37.5 °C. The ranges of normal body temperature need to be adjusted, especially for the lower values. When assessing body temperature it is important to take place of measurement and gender into consideration. Studies with random samples are needed to confirm the range of normal body temperature with respect to gender and age.

Patients with fibromyalgia syndrome were subgrouped by quantitative sensory testing (i.e., thermal pain thresholds). Subgroups show clinical differences in pain intensities, number of tender points, and sleep quality. Cold pain threshold was especially linked to these clinical aspects.

Changes in thermal sensibility for warmth, cold, heat pain and cold pain during nerve compression block of impulse conduction in myelinated fibres were studied in 20 healthy subjects. When mainly unmyelinated fibres were conducting, after 30-36 min of nerve compression, the pain threshold, induced by cold stimulation, was shifted towards higher temperatures (from 19.1 degrees C to 22.8 degrees C, mean values). Furthermore, the sensation of cold pain became more unpleasant and had a hot burning rather than a cold quality. These results indicate that a change in central decoding of the afferent input has occurred, possibly due to lack of inhibition normally exerted by concomitant activation of myelinated fibres. Whereas dramatic changes in the sensation of cold pain were observed during the course of nerve compression, no alteration in heat pain threshold was seen. This implies that heat pain threshold in hairy skin is due to activation of C nociceptor fibres without any significant contribution from myelinated nociceptor fibres. Furthermore, no gating from heat-sensitive myelinated fibre input was evident on heat pain threshold.

The role of gonadal hormones on pain sensations was investigated in normally menstruating women (n = 16) using the cold pressor test. Tolerance time, pain threshold, and pain intensity were examined once a week during a 4-wk period, and serum concentrations of 17beta-estradiol and progesterone were determined at each test session, which were classified into the early follicular phase, late follicular phase, early luteal phase, and late luteal phase, as determined by the first day of menses and the actual hormone levels recorded. A group of men (n = 10) of the same age interval was examined for comparison. The data show that pain threshold was reduced during the late luteal phase compared with the late follicular phase, and hormone analyses showed significant positive correlation between the progesterone concentration and lowered pain threshold and increasing pain intensity. Hormone analysis also showed an interaction between S-estradiol and S-progesterone on pain intensity, demonstrating that the increased perceived pain intensity that was associated with high progesterone concentrations was significantly reduced with increasing levels of estradiol. While no statistically significant sex differences in pain measurements were found, women displayed much more pronounced, and statistically significant, session-to-session effects than men, with increased pain threshold and decreased pain intensity with each test session. Hence, these data suggest that the changes in the serum concentration of gonadal hormones that occur during the menstrual cycle influence pain sensations elicited by noxious tonic cold stimulation and show that adaptation to the cold pressor test may be sex dependent.

Errors in body temperature measurement might seriously influence the evaluation of an individual's health condition. We studied individual variation, measurement technique and the equipment used when assessing body temperature. In the first part of the study, three volunteers performed repeated measurements for five mornings. In the second part, the morning rectal, oral, ear and axillary temperatures were measured once in 84 men and women (19-59 years). The repeated measurements showed a daily temperature difference of 0.1-0.4 degrees C in rectal and oral temperatures, 0.2 degrees C-1.7 degrees C in the ear and 0.1-0.9 degrees C in the axillary temperatures. In the sample of 84 subjects, men and postmenopausal women had a lower mean body temperature compared to premenopausal women. The mean deviation between rectal temperature, and oral, ear and axillary temperatures, respectively, was > 0.5 degrees C, with a large individual variation. In conclusion, in order to improve the evaluation of body temperature, the assessment should be based on the individual variation, the same site of measurement and no adjustment of oral, ear or axillary temperatures to the rectal site.

The aim of this study was to describe and analyse nursing documentation based on an electronic patient record (EPR) system in primary health care (PHC) with emphasis on the nurses' opinions and what, according to the nursing process and the use of the keywords, the nurses documented. The study was performed in one county council in the south of Sweden and included 42 Primary Health Care Centres (PHCC). It consisted of a survey, an audit of nursing records with the Cat-ch-Ing instrument and calculation of frequencies of keywords used during a 1-year period. For the survey, district nurses received a postal questionnaire. The results from the survey indicated an overall positive tendency concerning the district nurses' opinions on documentation. Lack of in-service training in nursing documentation was noted and requested from the district nurses. All three parts of the study showed that the keywords nursing interventions and status were frequently used while nursing diagnosis and goal were infrequent. From the audit, it was noted that medical status and interventions appeared more often than nursing status. The study demonstrated limitations in the nursing documentation that inhibited the possibility of using it to evaluate the care given. In order to develop the nursing documentation, there is a need for support and education to strengthen the district nurses' professional identity. Involvement from the heads of the PHCC and the manufactures of the EPR system is necessary, in cooperation with the district nurses, to render the nursing documentation suitable for future use in the evaluation and development of care.

Pneumonia has been estimated to be the second most common infection in nursing-home residents. However, to the authors' knowledge, no such Swedish data are available. Therefore, this study investigated the incidence, risk factors, and 30 d case-fatality rate and clinical presentation of nursing home-acquired pneumonia (NHAP) in 234 nursing-home residents aged 66-99 y. Activities of daily living (ADL status), malnutrition and body mass index were measured at baseline. The residents were then followed prospectively during 1 y for symptoms and signs of pneumonia. Pneumonia was verified clinically and/or radiologically in 32 residents, corresponding to a yearly incidence of 13.7%. The 30 d case-fatality rate was 28%. Cough and sputum production were the most specific, and fever > or = 38.0 degrees C rectally and cognitive decline were the most common non-specific presenting symptoms. Chronic obstructive pulmonary disease, ADL status > 5 and male gender were risk factors for acquiring pneumonia. In conclusion, NHAP is associated with high morbidity and mortality in Sweden. In order not to delay treatment, it is necessary to be aware that specific symptoms of pneumonia may be lacking in the clinical presentation in the nursing-home setting.
