Surgical treatment of two post-traumatic pseudoaneurysms of genicular artery.

Pseudoaneurysms of the genicular arteries represent an extremely rare clinical occurrence. Nevertheless, young and athletic subjects, who are frequently exposed to direct joint trauma and subsequent reconstructive orthopedic surgery, are especially prone to developing these lesions. The aim of the present report was to describe two cases of a genicular artery pseudoaneurysm observed in young and healthy athletic male patients and successfully managed by surgical excision.

QT spatial dispersion and sudden cardiac death in hypertrophic cardiomyopathy: Time for reappraisal.

BACKGROUND: The 12-lead surface electrocardiographic (ECG) analysis is able to provide independent predictors of prognosis in several cardiovascular settings, including hypertrophic cardiomyopathy (HCM). The present single-center study investigated the possible ability of several ECG-derived variables in stratifying sudden cardiac death (SCD) risk and, possibly, in improving the accuracy of the 2014 European Society of Cardiology guidelines. METHODS: A total of 221 consecutive HCM outpatients were recruited and prospectively followed. All of them underwent a full clinical and instrumental examination, including a 12-lead surface ECG to calculate the dispersion for the following intervals: QRS, Q-Tend (QT), Q-Tpeak (QTp), Tpeak-Tend (TpTe), J-Tpeak (JTp), and J-Tend (JT). The study composite end-point was SCD, aborted SCD, and appropriate implantable cardioverter defibrillator (ICD) interventions. RESULTS: During a median follow-up of 4.4 years (25th-75th interquartile range: 2.4-9.4 years), 23 patients reached the end-point at 5-years (3 SCD, 3 aborted SCD, 17 appropriate ICD interventions). At multivariate analysis, the spatial QT dispersion corrected according to Bazett's formula (QTcd) remains independently associated to the study endpoint over the HCM Risk-SCD score (C-index 0.737). A QTcd cut-off value of 93ms showed the best accuracy in predicting the SCD endpoint within the entire HCM study cohort (sensitivity 56%, specificity 75%, positive predictive value 22%, negative predictive value 97%). CONCLUSION: Our data suggest that the QTcd might be helpful in SCD risk stratification, particularly in those HCM categories classified at low-intermediate SCD risk according to the contemporary guidelines.

Comparison of walking energy cost between an anterior and a posterior ankle-foot orthosis in people with foot drop.

OBJECTIVE: To compare walking energy cost between an anterior and a posterior ankle-foot orthosis in people with foot drop. DESIGN: Within-group comparisons. PARTICIPANTS: Twenty-three adults (14 women, 9 men; mean age 56.8 years (standard deviation 15.4)) with foot drop. METHODS: PARTICIPANTS were asked to walk for 5 min at their self-selected walking speed under 3 conditions: (i) with shoes only; (ii) with a posterior ankle-foot orthosis; (iii) with an anterior ankle-foot orthosis. Spatio-temporal gait para-meters (speed, step length and step frequency) and walking energy cost per unit of distance were assessed for each walking condition. A visual analogue scale was used to quantify participants' level of perceived comfort for the 2 orthosis. RESULTS: Gait spatio-temporal parameters were higher with anterior ankle-foot orthoses than with posterior ankle-foot orthoses or shoes only. Walking energy cost per unit of distance was lower with anterior than posterior ankle-foot orthosis or shoes only ((mean ± standard error) 3.53 ± 1.00 vs 3.94 ± 1.27 and 3.98 ± 1.53 J·kg-1·m-1 respectively; p < 0.05) and level of perceived comfort was higher with anterior ((mean ± standard error) 8.00 ± 1.32) than with posterior ankle-foot orthosis ((mean ± standard error) 4.52 ± 2.57; p < 0.05). CONCLUSION: In people with foot drop the use of anterior ankle-foot orthoses resulted in lower energy costs of walking and higher levels of perceived comfort compared with posterior ankle-foot orthoses. Anterior ankle-foot orthoses may enable people with foot drop to walk further with less physical effort than posterior ankle-foot orthoses.

Use of topiramate for glossodynia.

INTRODUCTION: Glossodynia is a multifunctional disorder characterized by painful sensations in the mouth and throat and especially on the tongue. It is commonly cured by long-term therapy with systemic regimens of anxiolytics, antidepressants, and anticonvulsants. CASE: We report here the case of a 65-year-old woman with a 4-month history of glossodynia. Clinical and laboratory evaluations performed the diagnosis of idiopathic glossodynia, and several treatments with carbamazepine and then with gabapentin induced the development of serious adverse reaction. Only treatment with topiramate has been able to induce a complete improvement of symptoms. DISCUSSION: The pathogenesis of idiopathic glossodynia remains unclear, since it recently has been suggested as a possible neuropathic basis of burning mouth syndrome, demonstrating an altered excitability in the trigeminal nociceptive pathway at peripheral and/or central nervous system level. The various mechanisms of topiramate, which act at different neural transmission levels, blocking sodium and calcium channels, enhancing GABA concentration, and decreasing glutamate function at postsynaptic site, may explain the effects of topiramate in our patient. CONCLUSION: Therefore, we suggest that topiramate could represent a useful therapeutic option in the treatment of glossodynia.
