Vertebroplasty provides an effective means of treating painful vertebral lesions although the majority of the literature relates to vertebroplasty using PMMA cement. The purpose of this study is to assess the safety and efficacy of vertebroplasty using Cortoss, a recently developed bis-GMA resin. Our newly established vertebroplasty service exclusively uses Cortoss cement and has a patient database which is updated on a regular basis using the medical records. To date, there are 34 patients on this database, mean age 66, in whom a vertebroplasty has been performed on 42 vertebral lesions with a mean of 2.2 ml of Cortoss injected into each lesion. The mean duration of follow up was 9.5 months. Eighty-two per cent of patients reported an improvement in their symptoms, while 79% required less analgesia post vertebroplasty. A total of 88.2% experienced no significant complications. In 38% there was an asymptomatic leakage of Cortoss. Four patients (11.8%) experienced significant complications: one asymptomatic PE, one episode of transient radicular leg pain, one generalized rash and one patient suffered retropulsion of the Cortoss due to further vertebral malignancy. Cortoss vertebroplasty provides comparable efficacy and safety to the published literature for PMMA.

Initial excision biopsy carried out in general practice does not lead to a poorer outcome. ABSTRACT Background:The incidence of melanoma is rising worldwide. Current Irish guidelines from the National Cancer Control Programme state suspicious pigmented lesions should not be removed in primary care. There are conflicting guidelines and research advising who should remove possible melanomas. Objectives: To determine whether initial diagnostic excision biopsy of cutaneous malignant melanoma in primary versus secondary care leads to poorer survival. Methods: Analysis of data comprising 7116 cases of cutaneous malignant melanoma from the National Cancer Registry Ireland between January 2002 and December 2011. Single predictor variables were examined by the chi-square or Mann-Whitney U test. The effects of single predictor variables on survival were examined by Cox proportionate hazards modelling and a multivariate Cox model of survival based on excision in a non-hospital setting versus hospital setting was derived with adjusted and unadjusted hazard ratios. Results: Over a 10-year period 8.5% of melanomas in Ireland were removed in a non-hospital setting. When comparing melanoma death between the hospital and non-hospital groups, the adjusted hazard ratio was 1.56 (95%CI: 1.08-2.26); (P ¼ .02), indicating a non-inferior outcome for the melanoma cases initially treated in the non-hospital group, after adjustment for significant covariates. Conclusion: This study suggests that initial excision biopsy carried out in general practice does not lead to a poorer outcome.
