Central mucoepidermoid carcinoma of the mandible deriving from odontogenic cyst: A case report and review of the literature

Mucoepidermoid Carcinoma (MEC) it can origin from a mandibular odontogenic cyst. We report the case of a 63‐year‐old man with MEC of the right retromolar trigonum of the mandibula. We performed a wide mandibular excision and immediate reconstruction with a fibula bone free flap.

Prognostic Stratification by Conventional Echocardiography of Patients with Aortic Stenosis: The “CAIMAN‐ECHO Score”

Background and Aim: Surgery is not recommended in asymptomatic patients with aortic stenosis (AS). However, prognosis of these patients is worse than retained. We built a simple score (named by the acronym “CAIMAN”) for stratifying asymptomatic patients with AS according to the different risk for cardiovascular events. Material and Methods: Data from 141 patients with moderate‐to‐severe AS followed up for 36 months were analyzed. The end point “outcome” was defined as death of all causes or aortic valve replacement imposed by symptoms or hospital admission for myocardial infarction and/or heart failure. The score was validated in 143 patients prospectively recruited in 2 different centers. Results: The 40 events occurred in the original cohort were associated with higher aortic transvalvular peak jet velocity, calcium score, and observed/predicted left ventricular (LV) mass ratio. Based on the hazard ratios of Cox analysis, the score was calculated as follows: calcium score 1–3 = 1 point, 4 = 6 points; transvalvular peak jet velocity ≤3.6 m/sec = 1 point, 3.6 m/sec = 3 points, observed/predicted LV mass ratio ≤110% = 1 point, >110% = 3 points. After a mean period of 28 ± 18 months, event‐free survival was 18%, 42%, 91%, and 96% in the 4 quartiles of echo score. The accuracy of the score in predicting events was 84% and 77% (P = 0.09) in the original and validation cohort, respectively. Conclusions: The CAIMAN‐ECHO score is a simple and feasible tool useful for an accurate prognostic stratification of patients with asymptomatic moderate‐to‐severe AS.     

Sativex-induced neurobehavioral effects: causal or concausal? A practical advice!

Nabiximols (Sativex) is an oromucosal spray, containing delta-9 tetrahydrocannabinol (THC) and cannabidiol (CBD), used as treatment for unresponsive spasticity in multiple sclerosis (MS) patients. Sativex is thought to not affect cognition or induce any psychiatric problem at the doses generally used. Nonetheless, it is known that the concomitant use of more than one muscle-relaxant drugs can result in additive neuropsychiatric effects. Herein we describe a case of a woman affected by MS and treated with baclofen and methylprednisolone, who developed important behavioral changes, including suicidal ideation, after 4 weeks of Sativex administration. We are not completely able to state if Sativex alone was responsible for our patient’s psychiatric symptoms, in reason of the concomitant use of the other drugs.In conclusion, physicians should pay more attention when prescribing drugs to MS patients affected by spasticity, including Sativex, since neurobehavioral side effects may emerge especially in predisposed individuals.     

Validity and reliability of the Unified Classification System applied to periprosthetic femur fractures: a comparison with the Vancouver system

Abstract

Objective: The Unified Classification System (UCS) presents itself as an evolution of the Vancouver Classification (VCS) for the evaluation of periprosthetic fractures of the proximal femur (PPF). The aim of our study was to highlight any loss of reproducibility or validity of the new classification system, compared to the previous one.

Material and methods: We tested the interobserver and intraobserver agreement using 40 PPF clinical cases. Each classifying subtype of the UCS and VCS was present in at least two cases. Six experienced hip surgeons (Senior Surgeon, SS) and 5 surgeons in training (Junior Surgeon, JS) classified the clinical cases, using VCS and UCS. The validity of both classifications was then tested with intraoperative surveys.

Results: The mean κ value for interobserver agreement for the VCS in the JS group was 0.65 and 0.81 for the SS group. The mean κ value for interobserver agreement for the UCS in the JS group was 0.63 and 0.65 for the SS group. The mean κ value for intraobserver agreement for the VCS in the JS group was 0.71 and 0.73 for the SS group. The mean κ value for intraobserver agreement for the UCS in the JS group was 0.72 and 0.7 for the SS group. Validity analysis showed a moderate agreement for the VCS and a good agreement for the UCS.

Conclusion: The UCS completes the Vancouver classification, expanding it. It is reliable, despite the increase in classification categories and number of parameters to evaluate, with a slightly higher validity.
