BACKGROUND: Pre-incisional treatment with either N-methyl-D-aspartate (NMDA) receptor antagonists or non-steroidal anti-inflammatory drugs (NSAIDs) improves postoperative pain relief. This study examines the effect on postlaparoscopic cholecystectomy (LC) pain of a combination of dextromethorphan (DM), a NMDA-receptor antagonist, and tenoxicam, a NSAID, given preoperatively. METHODS: Eighty-eight ASA I or II patients scheduled for LC were entered into a randomized, double-blind study and randomly allocated to one of four groups. Controls received 20 mg (4 ml) of chlorpheniramine maleate (CPM) IM and 4 ml of normal saline (N/S) IV. Group DM received 40 mg of DM (containing 20 mg of CPM) IM and 4 ml of N/S IV. Group T were given CPM 20 mg IM, and tenoxicam 40 mg (4 ml) IV. Group DM + T were given DM 40 mg (containing 20 mg of CPM) IM, and tenoxicam 40 mg IV. All treatments were given 30 min before skin incision. Analgesic effects were evaluated by Visual Analog Scale (VAS) pain scores at rest and during coughing, at 1, 2, 4, 12, 24 and 48 h after surgery. The time to the first request for meperidine for pain relief, and total meperidine consumption, were recorded for 48 h after surgery. RESULTS: Compared to controls, patients given DM and DM + T first requested meperidine significantly later, had lower meperidine consumption, made fewer requests for meperidine, and had lower pain scores. There were significant differences between the DM + T and T groups at 2 and 4 h in both resting and incident VAS pain scores, the incidence of meperidine requests and the time to first meperidine injection. There were significant differences between groups DM and T at 1 h for resting pain and at 2 and 4 h for incident pain. Except for a significant difference in the incident pain score 1 h after surgery, there were no other differences in pain scores between the DM and DM + T groups. Neither synergistic nor antagonistic interaction was observed between DM and tenoxicam. CONCLUSIONS: The results suggest that pretreatment with DM, but not tenoxicam, provides significant pre-emptive analgesia for postoperative pain management in patients after LC surgery. Combining DM and tenoxicam also gives good pain relief. 相似文献
AIM: Metastases of melanoma are frequent. On the gastro-intestinal tract, commonest localizations are small bowel, stomach and colon. Surgical treatment of digestive metastases from melanoma is not well known and its value is still debated. PATIENTS AND METHODS: Medical records of 10 patients (six female and four male) operated for metastatic melanoma to gastro-intestinal tract were reviewed to determine results of surgery. RESULTS: Gastro-intestinal metastases were symptomatic in eight patients (abdominal pain in three, bowel obstruction in three, abdominal mass and obstructive jaundice in one each). Two patients had anemia. Diagnosis has been suggested by imaging in seven patients and endoscopy in three. All patients were operated on by laparotomy for resection of metastases located on small bowel in four patients, gallbladder in two, stomach in two and colon in two. Complete resection suppressed symptoms in nine cases. In one patient, resection was incomplete but provided satisfying symptomatic relief. One patient died at day 3; in other patients, median survival was 18 months (range: 3-120). CONCLUSION: In a patient with previous history of melanoma, digestive symptoms indicate morphological explorations due to suspicion of metastases to gastro-intestinal tract. Surgical treatment of these metastases is usually palliative but, in some cases, allows long-term survival. 相似文献
Aim: To determine if there are correlations between the physical fitness of young soccer players assessed by field and laboratory testing. METHODS: Thirty four male soccer players took part in the study (mean (SD) age 17.5 (1.1) years, height 177.8 (6.7) cm, weight 70.5 (6.4) kg). Maximal oxygen uptake (VO(2)MAX) during treadmill running and vertical jump height on a force platform were measured in the laboratory. Field tests consisted of a soccer specific endurance test (Bangsbo test) and 30 m sprint with 10 m lap times. RESULTS: The Bangsbo test correlated with the lowest velocity associated with VO(2)MAX (vVO(2)MAX; R(2) = 0.55, p<0.001), but not with VO(2)MAX. Sprint times at 30 m and 20 m were related to peak extension velocity and peak extension force measured during vertical jumping, but not to vertical jump height per se. The jumping force and velocity could explain 46% of the 30 m sprint performance (R(2) = 0.46, p<0.001). CONCLUSION: The Bangsbo test and 30 m sprint test correlate with vVO(2)MAX and vertical jump force and velocity respectively. The Bangsbo test does not give a good estimate of VO(2)MAX in young soccer players. 相似文献
The treatment and management of chronic conditions during adolescence pose specific issues that need to be appropriately handled by health professionals. In this paper, questions related to disclosure of the diagnosis, the management of adherence to therapy, the need for an interdisciplinary network approach, lifestyles' anticipatory guidance and prevention, and the transition into an adult healthcare setting are reviewed. Special areas such as the issue of life threatening diseases and the ethical aspects of the treatment of chronic conditions are also discussed. 相似文献

Aims: To investigate the occupational and personal factors associated with lumbar spondylolisthesis in taxi drivers.
Methods: Cross-sectional analysis of the baseline data from the Taxi Drivers' Health Study cohort. Information was retrieved from the medical records of standardised lumbosacral spine plain films, age, and anthropometric measures of 1242 subjects. Acquired spondylolisthesis (ASL) was defined as non-lytic spondylolisthesis involving lumbar spines above L5. Questionnaires were used to gather information on demographic features, health behaviours, exercise, work related physical and psychosocial factors, and driving time profiles. Multiple logistic regression was used to model the odds ratio (OR) for prevalent ASL cases associated with personal and occupational factors.
Results: A total of 40 cases (3.2%) of ASL were diagnosed. Among those driving 5 years, 6–15 years, and >15 years, the estimated prevalence of lumbar spondylolisthesis was 1.1%, 2.4%, and 7.1% respectively. Results of multiple logistic regression suggested that taxicab driving >15 years (OR = 3.4, 95% CI 1.1 to 10.7, compared to driving 5 years), age (OR = 2.6, 95% CI 1.1 to 6.6 for age 46–55; and OR = 4.8, 95% CI 1.8 to 12.9 for age >55), body mass index 25 kg/m2 (OR = 2.2, 95% CI 1.1 to 4.6), and frequent strenuous exercise (OR = 2.2, 95% CI 1.1 to 4.5) were significantly associated with higher prevalence of spondylolisthesis. There was a consistent likely exposure-response relation between professional seniority and ASL prevalence.
Conclusions: Longitudinal studies are needed to confirm the observed association between professional driving and spondylolisthesis, and to examine further the specific occupational exposures accountable for this association.
