RESUMO
PURPOSE: Self-cutting injuries have a low mortality rate, but this type of injuries has special clinical significance because they have the potential of leading to devastating disability and repeated suicide attempts. The purpose of this study is to analyze the nature and outcomes of wrist-cutting injuries. MATERIAL AND METHOD: A retrospective study was designed in order to investigate 41 suicide attempts by wrist cutting attended to Uludag University Faculty of Medicine Emergency Department between June 2008 and December 2014. The patients were analyzed for age, gender, alcohol intake, psychological state, prior suicide attempts, and clinical features such as injury side, injury pattern, and used tool. RESULTS: It was seen that the severity of wrist-cutting injury variates between gender and age. CONCLUSION: Alcohol or drug consumption and having a diagnosed psychiatric disorder create a higher risk for extensive wrist lacerations. It was seen that skin only lacerations were most likely to repeat the act and therefore are most in need of psychiatric intervention. LEVEL OF EVIDENCE: Level III, retrospective study.

A method for line interference reduction to be used in signal-averaged electrocardiography (SAECG) systems is proposed and its performance is analyzed. This new method is an adaptation of a previously reported technique for removal of line interference from conventional electrocardiograms. It involves the recording of a line reference signal simultaneous with the lead signals, so that a shifted and scaled version of it can be used to subtract line interference from the leads. It is shown that this line interference subtraction method can reduce line interference effectively and without introducing any additional noise into the ECG signal. It is also shown that Late Potential diagnostic decisions are not altered when this filter is applied. It is recommended that this technique be used in SAECG when line interference is unavoidable.
