Efficacy of erenumab and factors predicting response after 3 months in treatment resistant chronic migraine: a clinical service evaluation

BackgroundCalcitonin gene-related peptide (CGRP) inhibitors have been developed as options for treatment of chronic and episodic migraine. We present our experience of the use of erenumab in a tertiary headache centre.MethodsThis was a prospective clinical audit of all patients commenced on erenumab following a locally agreed pathway and criteria over a consecutive period. Patients received monthly erenumab 140 mg for 3 months. Data were collected prospectively at baseline and 3 months follow up.ResultsOne hundred three patients were commenced on erenumab during the study period. Patients had tried a median of 7 previous prophylactics, including onabotulinum toxin A in 94%. At 3 months there was a reduction in median total (28 to 20, 29% reduction, p < 0.0001) and severe (15 to 5, 67% reduction, p < 0.0001) headache days. 39.8% of patients achieved at least a 30% reduction in total headache days; 61.8% of patients achieved at least a 50% reduction in severe headache days. Meeting either of these thresholds was considered a positive response, 68% of patients achieved this. Presence of daily headache pattern was negatively associated with response, (56% response vs. 90% without daily headache, p = 0.0003). There was no association between age, gender, presence of medication overuse or number of previously tried prophylactic treatments and response to erenumab. 43% of patients reported at least one adverse effect, most commonly constipation (26%); treatment was discontinued in 3 patients due to adverse effects.ConclusionsErenumab was an effective treatment for chronic migraine in this treatment resistant population over 3 months of follow up. Presence of daily headache predicted poorer response but there was still a significant positive response rate in this group.     

A case of "fresh rupture" after open repair of a ruptured Achilles tendon

We present the case of Achilles tendon rupture in a 54-year-old man while rehabilitating after end-to-end open repair of an acute Achilles tendon rupture. Re-rupture after surgical repair of Achilles tendon is well known. The present case, however, is atypical, because the second rupture occurred significantly proximal to the first rupture. To our knowledge, this is the first time this has been described in English language studies. We have termed this incident a fresh rupture. A gastrocnemius turndown flap was used to repair the fresh rupture, which led to a satisfactory recovery. This case report serves to inform surgeons of the existence of this type of Achilles tendon rupture, while considering the possible etiologies and suggesting a technique that has been shown to be successful in the present case.     

Comparative evaluation of two two-dimensional gel electrophoresis image analysis software applications using synovial fluids from patients with joint disease

The proteomic composition of synovial fluid (SF) may hold clues to understanding the molecular basis of arthritis. However, the highly viscous nature and proteomic complexity of SF present a challenge when analyzing results obtained by two-dimensional gel electrophoresis (2D-GE). Several software applications are available for analyzing 2D-GE images. Despite inherent strengths and weaknesses, no comparison between these applications has been reported using SF or any human fluid specimens. We evaluated two common software packages — PDQuest and Progenesis Workstation — for spot detection, matching, and quantitation of 2D-GE images of SF from four patients with arthritic disease. Initially, whole 2D-gel images were analyzed for spot detection, which suggested that PDQuest is more consistent than Progenesis; however, PDQuest appeared to require more user intervention than Progenesis. Subsequently, two small areas (spots well resolved and spots not well resolved) were selected from each gel image, which were analyzed by the software for spot detection, matching, volume, and resolution. These analyses suggest that both tools can quantify well-resolved spots relatively consistently when compared with manual spot detection (the gold standard). The 3D viewer option offered by both tools enables correct spot identification and matching. The strengths and weaknesses of these computer tools can provide guidance in the choice of a particular workstation for identifying biomarkers of arthritis.     

Renal allograft tuberculosis: report of three cases and review of literature

Renal transplant recipients are prone to a variety of infections due a persistent immunodepleted state. Incidence of tuberculosis in this population is much higher compared with the general population. While pulmonary tuberculosis still remains the commonest form in this population, renal allograft tuberculosis is very rare. We report two cases of isolated allograft tuberculosis and one case of allograft tuberculosis with coexistent pleuro-pulmonary and bone marrow involvement. All three cases had presented with pyrexia of unknown origin, wherein despite extensive investigations the cause was not found. In two cases the diagnosis was confirmed on histology. Two cases responded to non-rifampicin-based modified antitubercular treatment and one to conventional four-drug Rifampicin-based regimen. Graft function improved in two cases while in one case the graft was lost. Tuberculosis involving the renal allograft is a potential cause for graft dysfunction/loss and requires a high index of suspicion for diagnosis. Timely detection and early institution of therapy can help save the renal allograft.     

Vattikuti Institute Prostatectomy: a single-team experience of 100 cases

PURPOSE: To analyze the outcomes of the first 100 patients undergoing robotic radical prostatectomy by a single surgical team. PATIENTS AND METHODS: From August 2001 to May 2002, we performed robotic radical prostatectomy in 100 patients with localized prostate cancer. The mean age was 60 +/- 0.67 years (SEM), the body mass index 27.5 +/- 0.35, the preoperative prostate specific antigen concentration 7.2 +/- 0.86 ng/mL, and follow-up 5.5 +/- 0.24 months. Thirty-eight patients also underwent pelvic lymph node dissection. We used the da Vinci surgical system and a subperitoneal approach (the Vattikuti Institute Prostatectomy; VIP). This is a prospective outcomes analysis of these patients. RESULTS: The mean operating time was 195 +/- 5.0 minutes, and the mean blood loss was 149 +/- 11.8 mL. No patient required blood transfusion. The stages of the cancers were pT(2a) in 21, pT(2b) in 64, pT(3a) in 5, pT(3b) in 9, and pT(3b)N(1) in 1. The positive surgical margin rate was 15%. At 1, 3, and 6 months, the continence rates were 37%, 72%, and 92%, respectively, and the potency rates were 11%, 32%, and 59%. CONCLUSION: The VIP is a safe operation with excellent operative parameters, low morbidity, and good surgical margins. The early functional results are promising.     

Intra-ocular pressure changes associated with intubation with the intubating laryngeal mask airway compared with conventional laryngoscopy

This open, prospective, randomised study was designed to evaluate the changes in intra-ocular pressure and haemodynamics after tracheal intubation using either the intubating laryngeal mask airway (ILMA) or direct laryngoscopy. Sixty adult patients, ASA physical status 1 or 2 with normal intra-ocular pressure were randomly allocated to one of the two techniques. Anaesthesia was induced with propofol followed by rocuronium. Tracheal intubation was performed using either the ILMA or Macintosh laryngoscope. Intra-ocular pressure, heart rate and blood pressure were measured immediately before and after tracheal intubation and then minutely for five minutes. In the laryngoscopy group there was a significant increase in intra-ocular pressure (from 7.2+/-1.4 to 16.8+/-5.3 mmHg, P<0.01), which did not return to pre-intubation levels within five minutes, and also in mean arterial pressure after tracheal intubation, which returned to baseline levels after five minutes. In the ILMA group there were no significant changes in intra-ocular pressure (from 7.6+/-1.8 to 10.4+/-2.8 mmHg, P >0.05) or mean arterial pressure after tracheal intubation. Time to successful intubation was longer with the ILMA, 56.8+/-7.8 seconds, compared with the laryngoscopy group, 33+/-3.6 seconds (P<0.01). Mucosal trauma was more frequent with the ILMA (eight of 30) compared with the laryngoscopy group (three of 30) (P<0.01). The postoperative complications were comparable. In terms of minimising increases in intra-ocular pressure and blood pressure, we conclude that the ILMA has an advantage over direct laryngoscopy for tracheal intubation.     

Satisfaction and regret after open retropubic or robot-assisted laparoscopic radical prostatectomy

BACKGROUND: To counsel patients adequately, it is important to understand the variables influencing satisfaction and regret following prostatectomy. OBJECTIVE: To identify independent predictors for satisfaction and regret after radical prostatectomy. DESIGN, SETTING, AND PARTICIPANTS: Patients who had undergone retropubic radical prostatectomy (RRP) or robot-assisted laparoscopic radical prostatectomy (RALP) between 2000 and 2007 were mailed cross-sectional surveys composed of sociodemographic information, the Expanded Prostate Cancer Index Composite (EPIC), and questions regarding satisfaction and regret. MEASUREMENTS: Sociodemographic variables, perioperative complications, type of procedure, length of follow-up, and EPIC scores were evaluated as independent predictors of satisfaction and regret in multivariate logistic regression analysis. RESULTS AND LIMITATIONS: A total of 400 patients responded (response rate 61%) of whom 84% were satisfied and 19% regretted their treatment choice. In multivariate analysis, lower income (odds ratio [OR], 0.08; 95% confidence interval [CI], 0.03-0.23), shorter follow-up (OR, 0.63; 95% CI, 0.41-0.98), having undergone RRP versus RALP (OR, 4.45; 95% CI, 1.90-10.4)], urinary domain scores (OR, 2.70; 95% CI, 1.60-4.54), and hormonal domain scores (OR, 2.01; 95% CI, 1.30-3.12) were independently associated with satisfaction (p相似文献
