Penn classification in acute aortic dissection patients.

OBJECTIVE: The objective of this study was to evaluate the effectiveness of the Penn classification in predicting in-hospital mortality after surgery in acute type A aortic dissection patients. METHODS: We evaluated 58 patients (42 men and 16 women; mean age 62.17 ± 10.6 years) who underwent emergency surgery for acute type A aortic dissection between September 2003 and June 2010 in our department. We investigated the correlation between the pre-operative malperfusion and in-hospital outcome after surgery. RESULTS: Twenty-eight patients (48%) were Penn class Aa (absence of branch vessel malperfusion or circulatory collapse), 11 (19%) were Penn class Ab (branch vessel malperfusion with ischaemia), 5 (9%) were Penn class Ac (circulatory collapse with or without cardiac involvement) and 14 (24%) were Penn class Abc (both branch vessel malperfusion and circulatory collapse). The number of patients with localized or generalized ischaemia or both, Penn class non-Aa, was 30 (52%). In-hospital mortality was 24%. In-hospital mortality was significantly higher in Penn class Abc and Penn class non-Aa. Intensive unit care stay, hospital ward stay and overall hospital stay was longer in Penn class non-Aa vs Penn class Aa. De Bakey type I dissection and type II diabetes mellitus were associated with in-hospital mortality. CONCLUSION: Preoperative malperfusion is important for the evaluation of patients with acute aortic type A dissection. The Penn classification is a simple and quick method to apply and predict in-hospital mortality and outcomes.

Smoking, diabetes, blood hypertension: possible etiologic role for Peyronie's disease? Analysis in 279 patients with a control group in Sicily.

OBJECTIVE: To assess the proportion of patients with Peyronie's Disease (PD) and the possible association with its potential risk factors in the general population of the central and western Sicily in our weekly andrological outpatient clinic. MATERIALS AND METHODS: We recruited a sample of 279 consecutive patients consulting our andrological outpatient clinic. Two arms were created: the first one composed by PD patients (men with symptoms suggestive for PD), the second one composed by patients with other andrological diseases (control arm). For each patient we evaluated the age, cigarette smoking, diabetes, blood hypertension and erectile function. In the PD arm we administered validated questionnaires to determine the erectile function status by the International Index of Erectile Function 5 (IIEF-5) and the pain status during erection by the Visual Analogue Scale (VAS). A univariate analysis was conducted using R software. RESULTS: We enrolled 279 consecutive patients. The number of PD patients was 97 (34,7%). The univariate analysis showed a correlation between PD and cigarette smoking (p = 0.0242), blood hypertension (p < 0.001), erectile dysfunction (p < 0.001). No significant association was observed between diabetes and PD (p = 0.358). The median age of PD arm was 60 years and the median age of the control arm was 63,5 years; therefore the median age of PD arm resulted lower than the median age of the control arm (p = 0,031). CONCLUSIONS: Peyronie's disease is more common than we might think; furthermore it can be diagnosed among young patients. According to our results, cigarette smoking and blood hypertension may be considered statically significant risk factors for developing PD. On the contrary diabetes seems not to be a risk factor for PD. According to our results PD should be sought also in young patients. Further studies are necessary to confirm that removing the indicated risk factors may reduce the incidence of PD.
