ABSTRACT

The present study reports offender, victim and offence characteristics of the entire population of known serial homicide offenders identified in Italy between 1848 and 2019 (59 offenders, 244 victims, of whom 50.4% were men, and 21.7% were sex workers). We found that most of the offenders (72.4%) had a personality disorder. The offenders' age during their series was 35.1 (SD = 11.3) years, on average. Sexual elements were found in 28.4% of the crime scenes. The median time interval between homicides was 2.8 months. Also, we investigated the consistency of the offence characteristics over the series and found significant correlations between the offence characteristics between a previous and the subsequent homicide.

ABSTRACT

BACKGROUND: The aim of this study was to compare the short-term outcomes of laparoscopic right hemicolectomy between intracorporeal (IA) and extracorporeal (EA) anastomosis techniques. METHODS: A retrospective chart review of 77 consecutive patients who underwent laparoscopic right hemicolectomy from January 2016 to June 2018 was performed. The intracorporeal group included 36 patients and the extracorporeal group 41 patients. RESULTS: Patient demographics and disease-related characteristics were similar. Mean operative time was 152±38.3 minutes in IA vs. 148±34.8 minutes in EA (P=0.664). IA was not associated with less overall postoperative complications and decreased rate of surgical site infections. There was no statistically significant difference in the incidence of postoperative leak, length of stay, mortality in both groups. There was no perioperative difference in median number of lymph node harvested. There was statistically significant difference in the length of larger incision (50 [50-70] mm in IA vs. 80 [70-100] mm in EA; P<0.001), length of the specimen (323±52.7 mm in IA vs. 295±64.7 mm in EA; P<0.05), free tumor margin (113.6±47.4 in IA vs. 75.6±37.4 mm in EA; P<0.001). There was a statistically significant difference in IA in the less postoperative use of analgesics (P<0.032) and return of bowel function (P<0.021). CONCLUSIONS: IA seems feasible and safe; it does not significantly affect the length of surgery, and it guarantees maintenance of radical oncological standards. Furthermore, IA significantly improves cosmesis and patient comfort postoperatively, reducing the rates of emesis, which leads to higher rates of early regular diet tolerance. Therefore, laparoscopic right hemicolectomy with intracorporeal anastomosis is associated with improved short-term outcomes.

ABSTRACT

INTRODUCTION: The gastric volvulus is a rare condition in which the stomach, or part of it, rotates on its axis, for over 180°, constituting a surgical emergency. Even more rare is gastro-gastric intussusception. A delay in their diagnosis and treatment can have fatal consequences PRESENTATION OF CASE: An 82-year-old woman was admitted to the Surgery Unit with a two-day history of abdominal pain associated at first with coffee vomiting and, subsequently, with unproductive retching and oligoanuria. Physical examination showed severe dehydration, fever, at the abdominal level, palpation caused a marked tenderness of all quadrants, with signs of peritonism. Laboratory test showed showed neutrophilic hyperleukocytosis and high C reactive protein level. Abdominal computed tomography revealed an acute intrathoracic gastric volvulus and a gastrogastric intussuception. The patient was submitted to exploratory laparotomy, subtotal gastrectomy with Roux en Y anastomosis and simple plastic of the esophageal hiatus. At the end of the surgery, however, the patient died of your septic shock. DISCUSSION: The traditional treatment for a patient with acute gastric volvulus is an immediate surgical intervention to derotate the stomach and prevent vascular insufficiency. In the presence of necrosis or gastric perforation, resection should be performed. The few cases of gastrogastric intussusception described in the literature have been treated with sub-total gastrectomy and gastro-jejunal anastomosis. Any delay in diagnosis and treatment can prove fatal. CONCLUSION: Intrathoracic Gastric Volvulus and, even more, retrograde gastrointestinal intussusception are very rare pathologies, difficult to diagnose.

ABSTRACT

Simulated interviews in alleged child sexual abuse (CSA) cases with computer-generated avatars paired with feedback improve interview quality. In the current study, we aimed to understand better the effect of different types of feedback in this context. Feedback was divided into feedback regarding conclusions about what happened to the avatar (outcome feedback) and feedback regarding the appropriateness of question-types used by the interviewer (process feedback). Forty-eight participants each interviewed four different avatars. Participants were divided into four groups (no feedback, outcome feedback, process feedback, and a combination of both feedback types). Compared to the control group, interview quality was generally improved in all the feedback groups on all outcome variables included. Combined feedback produced the strongest effect on increasing recommended questions and correct conclusions. For relevant and neutral details elicited by the interviewers, no statistically significant differences were found between feedback types. For wrong details, the combination of feedback produced the strongest effect, but this did not differ from the other two feedback groups. Nevertheless, process feedback produced a better result compared to outcome feedback. The present study replicated previous findings regarding the effect of feedback in improving interview quality, and provided new knowledge on feedback characteristics that maximize training effects. A combination of process and outcome feedback showed the strongest effect in enhancing training in simulated CSA interviews. Further research is, however, needed.

ABSTRACT

Cognition research suggests that allocating attention resources to evolutionarily relevant stimuli is facilitated suggesting that sexual stimuli interfere with human information processing. In a group of gay (n = 13) and straight men (n = 13) recruited in Finland, Germany and Italy, we investigated if and how sexually relevant visual stimuli affect information processing of both a target one (T1) and a subsequent target two (T2) in a dual target rapid serial visual presentation procedure. We hypothesized that: (1) due to the attentional blink (AB) phenomenon, the accuracy of reporting of T2 would decrease when following accurately identified sexually preferred T1 compared to accurately identified non-sexually preferred T1; 2) due to the pop out effect, the accuracy of reporting of T1 and T2 would be relatively increased when T1 and T2 were sexually preferred by the participants compared to when they were not. Our findings did not support hypothesis 1 but supported hypothesis 2. We further found that the pop out effect had a good capacity to differentiate sexual preference between the groups of gay and straight men. We conclude that dual target rapid serial visual presentation can be used as an attention-based measurement to differentiate sexual preference in men. Limitations and the applicability in the field of measuring sexual preference were discussed.

ABSTRACT

The implicit assessment of pedophilic sexual interest through viewing-time methods necessitates visual stimuli. There are grave ethical and legal concerns against using pictures of real children, however. The present report is a summary of findings on a new set of 108 computer-generated stimuli. The images vary in terms of gender (female/male), explicitness (naked/clothed), and physical maturity (prepubescent, pubescent, and adult) of the persons depicted. A series of three studies tested the internal and external validity of the picture set. Studies 1 and 2 yielded good-to-high estimates of observer agreement with regard to stimulus maturity levels by two methods (categorization and paired comparison). Study 3 extended these findings with regard to judgments made by convicted child sexual offenders.

ABSTRACT

What is the future of Offender Profiling? Is it an important field of forensic science or is it only a glamorous art? After the trilogy "Daubert-Joiner-Kumho" and after the last version, in 2009, of the Federal Rules of Evidence (F.R.E.), the opinion of American Courts concerning the admissibility of scientific evidence has changed, and the questions above can now have new answers. The change is closely tied to the perceived difference between hard and soft sciences and, in this way, the new gatekeeping role of the Courts also concerns whether offender profiling can be regarded as scientific evidence and if offender profiling should be admitted in the Courtroom as scientific evidence. In this work we present a comprehensive review concerning the most important Court opinions in U.S.A, U.K., Canada and Australia, about reliability and admissibility of offender profiling, in its different forensic application, as scientific evidence, and we suggest how and when an expert witness in the field of offender profiling can, in the light of these opinions, be admitted in Court.

ABSTRACT

Choice-reaction time (CRT) is an experimental information-processing paradigm. Based on an interference effect in visual attention, the CRT method has been shown to be suitable for measuring sexual orientation in men and women. The present study assessed the potential of the CRT to identify deviant (i.e., pedophilic) sexual interest. Participants were patients from forensic-psychiatric hospitals: 21 child molesters and 21 non-sex offenders. The dependent variable was reaction time in an ostensible seek-and-locate task (i.e., identifying the position of a dot superimposed on a picture of a person). There was an interaction effect between stimulus age category and participant group status: Child molesters took longer to respond to pictures of children relative to pictures of adults. Non-sex offenders showed an opposite pattern (i.e., longer reaction times with pictures of adults than with pictures of children). In addition, the data supported the notion of sexual content induced delay: Subjects took longer for the task with nude stimuli than with clothed ones. A subtractive preference index, derived from the reaction times for child and adult stimulus material, allowed distinguishing participants from both groups almost perfectly (ROC-AUC = .998). We conclude that a match of sexual interest with properties of visual stimuli led to a cognitive interference effect: Attentional resources were drawn from the ostensible task of locating the dot towards exploring the picture. This opens up the possibility of using this interference effect (i.e., the delay of response times) for diagnostic purposes.

ABSTRACT

The purpose of the study was to test the potential utility of a geographical profiling approach for three separate series of rapes committed by a single offender. Two different mathematical distance-decay functions using either a normal distribution with a mean distance and standard deviation based on previous research or a truncated negative exponential function based on distances between crime sites in the series under investigation were applied to each of the series giving prioritised search areas the accuracy of which was then assessed. The prioritised area that had to be searched before the home base of the offender could be located varied from 7.60 km(2) or 2.15% of the total search area at its best to 15 1.10 km(2) or 42.66% at its worst for the normal distribution based on previous research and from 42.06 km(2) or 11.88% to no improvement when the truncated negative exponential function was used. The functions used showed less predictive ability when the offender was a commuter. Explanations for the variations in the findings as well as suggestions for improvements were outlined in the discussion.
