Migraine is a common, disabling disorder associated with considerable personal and societal burden. Current guidelines recommend triptans for the acute treatment of migraine unlikely to respond to less effective therapies. Rizatriptan is a second-generation triptan available in tablet or orally disintegrating tablet (wafer) formulations that offers several advantages over other members of its class. Rizatriptan is rapidly absorbed from the gastrointestinal tract and achieves maximum plasma concentrations more quickly than other triptans, providing rapid pain relief. Clinical trials have shown that rizatriptan is at least as effective or superior to other oral migraine-specific agents in the acute treatment of migraine, and has more consistent long-term efficacy across multiple migraine attacks. Rizatriptan has a favorable tolerability profile, and patients have reported greater satisfaction and a preference for rizatriptan over other migraine-specific agents. Improvements in quality of life reported with rizatriptan are consistent with its favorable efficacy and tolerability profiles. Notably, multi-attribute decision models that combine clinical data with patient- and physician-reported treatment preferences have identified rizatriptan as one of three triptans closest to a hypothetical “ideal”. The efficacy and tolerability of rizatriptan for the acute treatment of migraine have thus been well established.  相似文献

Background Laparoscopic colorectal surgery has been reported to have some advantages compared with open surgery. The purpose of this study was to evaluate the incidence of incisional hernias after elective open colorectal resection versus laparoscopic colorectal resection. Methods The study group consisted of 104 patients who underwent elective colorectal resection or reversal of a Hartmann’s procedure between November 2003 and March 2005. Baseline data were prospectively recorded on all patients. All were examined by an independent observer for evidence of incisional hernia after they had reached a minimum follow up of one year. Results At a median follow up of 22 (17–26) months, nine patients had died and 95 were reviewed. Of these, 32 underwent laparoscopic resection while 63 had open surgery. Patients were well matched for all baseline characteristics. The median length of the wound in the laparoscopic group was 9 cm (IQR: 8–11 cm) while in the open group it was 20.8 cm (IQR: 17–24 cm). There was no significant difference in incisional hernia rates between the groups (3 vs. 10, p = 0.52) or in those who had symptoms from their hernia (p = 0.773). Conclusions Laparoscopic colorectal resection does not appear to reduce incisional hernia rates when compared with open surgery. Large randomised trials are required to confirm these findings.  相似文献

STUDY DESIGN: A questionnaire survey. OBJECTIVES: To collate and analyze the views of the delegates who attended the European Cervical Spine Research Society (CSRS) meeting on the use of methylprednisolone for acute traumatic spinal cord injury. SUMMARY OF BACKGROUND DATA: The NASCIS II and III studies reported improved neurologic recovery in patients who were treated with methylprednisolone within 8 hours of their acute traumatic spinal cord injury. A number of reported commentaries have criticized these trials. A recent audit in the authors' regional spinal injuries unit in the United Kingdom found that a large percentage of patients were not receiving methylprednisolone. The authors decided to collate the views of the delegates at the CSRS regarding the use of steroids for acute traumatic spinal cord injury. METHODOLOGY: A questionnaire was created that took into account the positive reported findings as well as the criticisms of the NASCIS studies. Delegates who attended the European CSRS meeting completed this questionnaire. RESULTS: Seventy-five percent of the delegates answered that they used or recommended methylprednisolone in the treatment of acute traumatic spinal cord injury. Nevertheless, the delegates had an average of 1.5 reservations about administering methylprednisolone. The most common reservation was that they did not think the improvement conferred to the patients by administering methylprednisolone had been clinically or functionally proven. There were reservations about the validity of the statistical analysis used in the NASCIS studies and by the omission of a placebo group in NASCIS III. The majority of the delegates thought it was not medicolegally negligent to withhold the administration of methylprednisolone in the treatment of acute traumatic spinal cord injury. CONCLUSION: The use of methylprednisolone in the treatment of acute traumatic spinal cord injury is still controversial. It would appear from a recent prospective audit at the authors' spinal injuries unit that a large percentage of patients in the United Kingdom are not receiving methylprednisolone. Because so much doubt exists, the NASCIS studies should be repeated.  相似文献

Objective The pathogenesis of chronic anal fissure (CAF) remains incompletely understood but most are associated with a high resting anal pressure and reduced perfusion at the fissure site. To date, no major distinction has been made between anterior and posterior anal fissures and their aetiology and treatment. We compared anterior and posterior fissures in patients who have failed to respond to medical treatment with respect to their underlying aetiology, anal canal pressures and sphincter muscle integrity. Method Seventy consecutive patients (54 female:16 male) with a symptomatic CAF and 39 normal controls (19 female:20 male) without evidence of significant ano‐rectal pathology were prospectively assessed by manometry and anal endosonography. Results Anterior anal fissures were identified in a younger age group [33 years (IQR 26–37) vs 41 years (IQR 36–52)] and predominantly in women. Anterior fissure patients were significantly more likely to have underlying external anal sphincter defects compared with posterior fissures [OR 10.9 (95% CI 3.4–35.4)]. Maximum resting pressure was not significantly elevated for anterior fissures compared with controls (P = 0.316) but was significantly elevated in posterior fissures (P = 0.005). The maximum squeeze pressure was significantly lower in the anterior fissure group [167 cmH2O (IQR 126–196) vs 205 cmH2O (IQR 174–262), P = 0.004]. A history of obstetric trauma was significantly associated with anterior fissure location [OR 13.9 (95% CI 3.4–55.7)]. Conclusions Anterior anal fissures are associated with occult external anal sphincter injury and impaired external anal sphincter function compared with posterior fissures. These findings have implications for treatment, especially if a definitive procedure, such as lateral internal sphincterotomy, is considered.  相似文献

Fracture of the metatarsal head is uncommon, and reports of isolated osteochondral fracture of the metatarsal head are rare. Because of the distal location of the fracture, it is difficult to achieve and maintain reduction, and potential complications include avascular necrosis and subchondral fatigue fracture. The authors present a case of an osteochondral fracture in a 40-year-old man, which was treated by open reduction and internal fixation with a single twist-off screw, with good results 12 months postoperatively.  相似文献

BACKGROUND: Our aims in the present study were to estimate the influences of pain and urinary symptoms on quality of life, and to determine which of these two variables has the most predictive power with respect to quality of life in young men with chronic prostatitis-like symptoms. METHODS: Chronic prostatitis-like symptoms were measured by the National Institutes of Health-Chronic Prostatitis Symptom Index. Of the 28,841 men aged 20 years who lived in the study community, 18,495 men (a response rate 64.1%) agreed to participate in the study. A total of 1057 men who complained of symptoms indicative of chronic prostatitis were included in the study. The influences of pain and urinary symptoms on quality of life were determined using logistic regression analysis. The receiver operating characteristic (ROC) curve was used to estimate the predictive ability of each of these variables with respect to quality of life. RESULTS: Results from multivariate analysis showed that both pain and urinary symptoms were associated with an increased likelihood of impaired quality of life, although pain contributed more to a reduced quality of life than urinary symptoms. Relative to men who experienced mild pain, men who experienced moderate pain had a 3.9-fold risk of poor quality of life (odds ratio [OR], 3.87; 95% confidence interval [CI], 2.86-5.23; P < 0.001) and those who experienced severe pain had a 15.7-fold risk of reduced quality of life (OR, 15.68; 95% CI, 6.59-37.35; P < 0.001). Moderate urinary symptoms were associated with a 1.4-fold risk of bother (OR, 1.41; 95% CI, 1.01-1.99; P < 0.001) and severe urinary symptoms were associated with 2.4-fold risk (OR, 2.39; 95% CI, 1.37-4.12; P < 0.001), relative to mild urinary symptoms. Comparison of the effects of pain and urinary symptoms showed that pain severity had the most predictive power for bother, quality of life, and quality-of-life impact. The areas under the ROC curves for bother, quality of life, and quality-of-life impact were 71.3%, 69.3% and 72.5%, respectively. CONCLUSION: Urinary symptoms and pain might be associated with an increased likelihood of impaired quality of life in young men with chronic prostatitis-like symptoms. In addition, our findings suggest that pain severity is the most influential variable for determining quality of life in this population.  相似文献

BACKGROUND: Lung cancer is the leading cause of cancer mortality in the United States. Stage-specific survival is well documented in national data sets; however, there remains limited recording of longitudinal survival in individual centers. METHODS: The VistA Surgery Package was employed to list operations performed by the thoracic surgery service at one Veterans Administration (VA) Medical Center. RESULTS: During a period of 107 months, 416 thoracic operations were performed, 211 of them for lung cancer. Stage distribution was 66% stage I, 18% stage II, 12% stage III, and 4% stage IV. During follow-up, 102 patients died, 57 of them from disease-specific causes. Median survival was 39 months for stage I. Disease-specific median survival was 83 months for stage I, and 5-year survival was 52% (72% for stage IA and 32% for stage IB). CONCLUSIONS: Pulmonary resection offers high disease-free survival for early-stage lung cancer. Decentralized hospital computer programming (DHCP) allows individual oncology programs to reliably measure survival. Use of this important outcome measure in quality improvement programs facilitates realistic counseling of patients and meaningful assessments of practice effectiveness.  相似文献
