Hair toxicological analysis of infants and their mothers: a 5-year retrospective study focusing on cocaine.

Prenatal and infant exposure to drugs of abuse is an emerging social and public health problem affecting children health and which may relate to child abuse and neglect. Exposure to drugs of abuse may occur through different routes, including intrauterine, breastfeeding, accidental intake, passive inhalation, and intentional administration. Currently, cases of suspected exposure can be investigated by hair toxicological analysis, the interpretation of which is, however, often difficult, leading to consequent difficulties in the management of such cases. In order to provide a contribution in terms of interpretation of the analytical results, this study aimed to search for the possible existence of elements, from a toxicological point of view, indicative towards the route of exposure. A retrospective study was performed on cases of suspected exposure to drugs of abuse in children aged 0-1 year, evaluated at a University Hospital between 2018 and 2022. Data of children hair toxicological analysis were analyzed and then compared with those of their mothers, when available; 41.6% children tested positive for cocaine. The study found a significant correlation between cocaine and benzoylecgonine concentrations, and a benzoylecgonine/cocaine ratio that tends to decrease as the age of children increases. From the comparison with mothers, a child/mother cocaine concentration ratio lower than 1 was found in all cases of hair sampled within the first week of life, and a ratio greater than or equal to 1 in all cases in which the sampling was performed later. These results, if confirmed in a larger cohort, could represent a contribution in the interpretation of cases of infant exposure to drugs of abuse and be integrated in the context of their multidisciplinary evaluation.

Homicide and concealment of the corpse. Autopsy case series and review of the literature.

INTRODUCTION: The concealment of the body following a homicide undermines different moments of the forensic and medico-legal investigations. The aim of the present study is to provide an overview of the literature and the forensic casuistry of the Institute of Legal Medicine of Padova for analyzing and discussing diverse methodological approaches for the forensic pathologist dealing with covered-up homicides. MATERIAL AND METHODS: A literature review, updated until September 2019, was performed, and a literature pool of forensic cases was built. In-house cases were included by conducting a retrospective analysis of the forensic caseworks of Padova of the last 20 years. Data regarding epidemiology, methodology of assessment, methods of concealment, and answers to medico-legal issues were extracted for both data sets. RESULTS AND DISCUSSION: Seventy-eight papers were included in the literature review (78.2% being case reports or case series, 17% retrospective studies, and 6% experimental studies or reviews). Literature and in-house data sets consisted of 145 and 13 cases, respectively. Death scene investigation, radiology, toxicology, and additional analyses were performed in 20-54% of literature and 62-77% of in-house cases. Cover-up by multiple methods prevailed. Death was caused by head trauma in about 40% of cases (both data sets), strangulation in 21% of literature, and 7% of in-house cases, and was undetermined in 17% of literature and 7% of in-house cases. CONCLUSIONS: The methodology of ascertainment should be case-specific and based on a multidisciplinary and multimodal evaluation of all data, including those gained through novel radiological and/or analytical techniques.

A novel methodology for the objective ascertainment of psychic and existential damage.

Personal injury is a legal term for a physical or psychic injury suffered by the plaintiff under civil and/or tort law. With reference to non-pecuniary damages, the evidence itself of physical and/or psychic injury is not sufficient for damage compensation. The process of ascertaining impairments and/or disabilities which pertain to the "personal sphere" of the individual, such as pain and suffering, loss of amenity, and/or psycho-existential damage, poses particular difficulties in relation to the obtainment of scientific evidence. The "immateriality" and the subjective connotation of the personal sphere are, in themselves, critical issues. The clinical data obtained from the neuropsychological ascertainment find their essential prerequisite in the active participation of the examinee who, in legally relevant contexts (criminal law, civil law, insurance), may be "affected" by personal interests. The present manuscript presents a novel interdisciplinary methodology, experimented on a series of judicial and extra-judicial cases, aimed at the attainment of objectivity and accuracy eligible in relation to the judicial settlement of cases and other matters involving the ascertainment of peculiar aspects of non-pecuniary damage.

Sex differences and driving impairment related to psychoactive substances.

OBJECTIVE: The first aim of the study was to identify sex differences in the use of psychoactive substances among subjects with a previous driving under the influence (DUI) episode. The secondary objective was to propose specific strategies for medico-legal improvements. METHODS: This was a retrospective observational study that took place between June 1, 2019, and August 31, 2023. It was conducted on DUI subjects examined for reinstatement of their driver's license using an integrated medico-legal and toxicological approach. Ethyl glucuronide (EtG) and illicit psychoactive substances were determined from hair samples. We performed descriptive statistical analyses for the entire sample as well as separately by sex. Additionally, we conducted binary logistic regression analyses separately for males and females to identify protective/risk factors associated with previous road accidents and judgments of unfitness to drive due to excessive alcohol consumption (EtG ≥ 30 pg/mg). RESULTS: The study included 2,221 subjects, comprising 1,970 men and 251 women. Men exhibited a higher prevalence of tobacco, alcohol, and illicit psychoactive substance use. Women were more frequently co-users of alcohol and psychoactive substances and involved in road accidents at the time of DUI. Among the men, being married or having a partner was found to be a protective factor concerning past traffic accidents. For both sexes, a DUI episode with a blood alcohol concentration (BAC) exceeding 1.5 g/L or the co-ingestion of alcohol and drugs was identified as a risk factor for road accident involvement. For men, smoking more than 20 cigarettes per day and, for women, having a DUI episode with a BAC over 1.5 g/L were the main factors indicating unfitness to drive, as determined through high hair EtG levels (> 30 pg/mg). Women with a previous history of road accidents were less likely to have EtG levels of 30 pg/mg or more. CONCLUSIONS: The study confirmed sex differences in subjects with a previous DUI episode. A BAC exceeding 1.5 g/L or the simultaneous use of alcohol and drugs at the time of DUI necessitate careful assessment of both men and women seeking driver's license reinstatement. In women, a BAC exceeding 1.5 g/L is considered a risk factor for a subsequent judgment of unfitness to drive. The medico-legal assessment should also involve a thorough investigation of smoking habits in men, as these habits could be related to an increased risk of excessive alcohol consumption.

Ethyl glucuronide concentration in hair for detecting heavy drinking and/or abstinence: a meta-analysis.

In both clinical and forensic settings, hair analysis for ethyl glucuronide (HEtG) has been increasingly employed for diagnosing chronic excessive drinking and, more recently, for monitoring abstinence. This paper aims at meta-analysing published data on HEtG concentrations in teetotallers, social drinkers and heavy drinkers in order to evaluate the use of this marker in hair for identifying chronic excessive drinking and for monitoring abstinence. In May 2012, a systematic multi-database search retrieved 366 records related to HEtG and further screened for relevant publications in the field. Fifteen (4.1 %) records matched the selection criteria and were included in the meta-analysis. The mean and 95 % confidence intervals (CI) of HEtG concentrations in social drinkers (mean 7.5 pg/mg; 95 % CI 4.7-10.2 pg/mg; p < 0.001), heavy drinkers (mean 142.7 pg/mg; 95 % CI 99.9-185.5 pg/mg; p < 0.001) and deceased subjects with a known history of chronic excessive drinking (mean 586.1 pg/mg; 95 % CI 177.2-995.0 pg/mg; p < 0.01) were calculated. The ranges of mean values and 95 % confidence intervals for single studies involving teetotallers/social or social/heavy drinkers showed a partial overlap with a down-trespassing of both the 7 and 30 pg/mg thresholds for social and heavy drinkers, respectively. Although larger and well-designed population studies are required to draw any definitive conclusion, our data show that the cut-off of 30 pg/mg limits the false-negative effect in differentiating heavy from social drinkers, whereas the recently proposed 7 pg/mg cut-off value might only be used for suspecting an active alcohol use, and not for proving complete abstinence.

Severe delayed postpolypectomy bleeding in elder patient with post-polycythemia myelofibrosis.

BACKGROUND: The interest of the case lies in an unexpected delayed bleeding following an endoscopic procedure in a patient with post-polycythemia myelofibrosis. The case gives the opportunity to discuss the medical management and monitoring of patients with myeloproliferative disorders undergoing minimally invasive surgery interventions. CASE PRESENTATION: A 75 years old woman affected by post-polycythemia myelofibrosis underwent endoscopy polypectomy followed by a delayed major local bleeding. At the time of the endoscopy followed by bleeding, the platelet count was 837 × 109/L, haemoglobin 113 g/L, PCV 35,2% and WBC 20.22 × 106/L. No antithrombotic prophylaxis with low molecular weight heparin was used. Antiplatelet drug was withdraw seven days before endoscopy and restarted one week after the procedure. Polyp size was 11 x 19 mm and it was located on right side of the colon. CONCLUSION: There are some patients in whom current guidelines do not apply and our case stress the importance of myeloproliferative neoplasms as a risk factor for complications of endoscopic polypectomy. The delayed haemorrhage we observed suggest to strictly control the patient for a period longer than only one week also in case of antithrombotic treatment with antiplatelet drugs.

The clinical management of diabetic foot in the elderly and medico-legal implications.

Diabetic foot is a complex and challenging pathological state, characterized by high complexity of management, morbidity and mortality. The elderly present peculiar problems which interfere on one hand with the patient's compliance and on the other with their diagnostic-therapeutic management. Difficult clinical management may result in medico-legal problems, with criminal and civil consequences. In this context, the authors present a review of the literature, analysing aspects concerning the diagnosis and treatment of diabetic foot in the elderly which may turn out to be a source of professional responsibility. Analysis of these aspects provides an opportunity to discuss elements important not only for clinicians and medical workers but also experts (judges, lawyers, medico-legal experts) who must evaluate hypotheses of professional responsibility concerning diabetic foot in the elderly.

Ethical and medico-legal implications of capacity of patients in geriatric surgery.

OBJECTIVES: The aim of this study was to assess the decision-making capacity of elderly patients hospitalized in a geriatric surgery division, and the clinician's ability to assess that capacity. SUBJECTS AND METHODS: The study was conducted on patients (aged >66 years) undergoing surgical procedures. Exclusion criteria were a diagnosis of psychogeriatric disorders interfering with decision-making capacity; hearing or visual impairment; and inability to communicate. Patients previously declared legally incompetent were also excluded. The methodological approach consisted of additional interviews to collect data on patients' awareness of the reasons for their hospitalization, their informed consent, and their ability to sign a consent form. The interview was integrated with a clinical-behavioral assessment by means of the Mini-Mental State Examination and the Clock Drawing Test. Data were collected anonymously. RESULTS: The inclusion criteria were met by 123 patients, with a mean age ± SD of 77.65 ± 7.91 years (range 67-98). Their mean (±SD) Mini-Mental State Examination and the Clock Drawing Test scores were 24.53 ± 4.29 and 5.36 ± 2.41, respectively. Mild-to-severe cognitive impairment was identified in 39 patients (31.7%). The consent form was signed by 111 patients (90.25%), including 33 patients (29.72%) with mild-severe cognitive impairment; 18 patients (16.21%) were unaware of the reason for their admission to hospital. DISCUSSION: Many factors may interfere with elderly patients' ability to give their valid consent to treatment, and this study reveals that clinicians may overestimate their patients' decision-making capacity. Physicians should be aware of this problem, and intellectual capacity assessments and/or enhanced consent procedures should be considered when treating elderly patients.

Driving license regranting: Hair EtG, serum CDT, and the role of sociodemographic and medicolegal variables.

Driving under the influence (DUI) of alcohol is a road safety problem. Driving license regranting is based on the evaluation of medicolegal and toxicological variables that may include serum carbohydrate-deficient transferrin (CDT) and hair ethyl glucuronide (hEtG). The aim of the study was to compare the diagnostic performance of CDT and hEtG in a population of DUI offenders. Other factors potentially associated with heavy alcohol use were explored. The population included DUI offenders examined during the period of January 1, 2019, through June 30, 2022. Sociodemographic, medicolegal, and toxicological variables were collected. CDT in serum and EtG in head hair were determined in all subjects. Excessive alcohol intake (hEtG ≥30 pg/mg) was considered cause for unfitness to drive. Cohen's kappa coefficient was calculated. Descriptive analyses were performed using chi-square and Mann-Whitney tests. Variables significantly different between the groups were included in a multivariate binary logistic regression model. The sample encompassed 838 subjects (case group: 179, comparison group: 689). CDT exhibited poor agreement (κ = 0.053) with hEtG as the reference test. Lower education, age at DUI, heavy smoking, and GGT levels associated with heavy alcohol consumption differentiated the two groups. For DUI offenders, the use of CDT to assess heavy alcohol consumption is limited, possibly due to the time-window assessed, the time required for normalization, and the different amount of ethanol needed to reach higher CDT levels, in comparison to hEtG; thus, hEtG assessment is strongly recommended for this population. Heavy smoking, GGT, education, and age could be related to heavy alcohol consumption and higher risk of DUI.

AI and professional liability assessment in healthcare. A revolution in legal medicine?

The adoption of advanced artificial intelligence (AI) systems in healthcare is transforming the healthcare-delivery landscape. Artificial intelligence may enhance patient safety and improve healthcare outcomes, but it presents notable ethical and legal dilemmas. Moreover, as AI streamlines the analysis of the multitude of factors relevant to malpractice claims, including informed consent, adherence to standards of care, and causation, the evaluation of professional liability might also benefit from its use. Beginning with an analysis of the basic steps in assessing professional liability, this article examines the potential new medical-legal issues that an expert witness may encounter when analyzing malpractice cases and the potential integration of AI in this context. These changes related to the use of integrated AI, will necessitate efforts on the part of judges, experts, and clinicians, and may require new legislative regulations. A new expert witness will be likely necessary in the evaluation of professional liability cases. On the one hand, artificial intelligence will support the expert witness; however, on the other hand, it will introduce specific elements into the activities of healthcare workers. These elements will necessitate an expert witness with a specialized cultural background. Examining the steps of professional liability assessment indicates that the likely path for AI in legal medicine involves its role as a collaborative and integrated tool. The combination of AI with human judgment in these assessments can enhance comprehensiveness and fairness. However, it is imperative to adopt a cautious and balanced approach to prevent complete automation in this field.

Driving under the influence of cannabis: A 5-year retrospective Italian study.

INTRODUCTION: Cannabis consumption is associated with driving impairment and increased crash risk, endangering road safety. Toxicological analyses play a fundamental role in detecting a recent consumption of psychoactive substances. The aim of this study was to examine the concentration of cannabinoids in blood samples of driving-under-the-influence (DUI) offenders in order to investigate whether delayed sample collection affects the toxicological assessment of the offenders. MATERIALS AND METHODS: An observational retrospective study was performed using anonymized toxicological data referring to cannabis-related DUI offenders involved in road traffic accidents (RTA) or apprehended by the police from 1 January 2017-31 December 2021 archived at Legal Medicine and Toxicology Department of the University Hospital of Padova, Italy. RESULTS: In a total sample of 318 drivers, 143 blood samples tested positive for tetrahydrocannabinol (THC) and metabolites 11-hydroxy-Δ9-tetrahydrocannabinol (11-OH-THC) and 11-nor-Δ9-tetrahydrocannabinol-9-carboxylic acid (THC-COOH), and 173 blood samples were positive for THC-COOH with THC negative. In the first group, the mean concentrations of THC and THC-COOH were 4.05 ng/mL and 28.29 ng/mL, respectively. In THC-negative cases, the mean THC-COOH concentration was 7.3 ng/mL. The time elapsed between the event and sample collection varied from 15 min to 7 h (mean 2 h 29 min). The average estimated time elapsed after consumption of cannabinoids was 3 h 7 min (Model I) and 2 h 36 min (Model II). CONCLUSIONS: The present research discussed the main difficulties in the toxicological evaluation of drivers under the influence of Cannabis. Issues related to the time between RTA and sample collection, the laws and legal limits in force in various Countries were presented.

Journals publishing bio-medicolegal research in Europe.

Fragmentation of bio-medicolegal knowledge has led to a proliferation of ultra-specialised sub-disciplines and branches, often published in 'field-oriented' scientific journals.The aim of this work is to provide an in-depth analytical picture of bio-medicolegal sources of publication, within and outside the traditional conception of legal medicine. An extensive search of bio-medicolegal articles published in the last five and a half years was performed on the MEDLINE database according to MeSH terms combined with free-text protocols. We performed a systematic analysis of targeted journals after merging, selecting and categorising all retrieved records, taking into account data from the 2009 JCR Science Edition (released on June 2010); 1,037 different journals were identified, of which only 48 (4.6%) focus specifically on bio-medicolegal matters, and of which only seven (14.6%) have an impact factor (IF). Despite this apparent dispersion, 47% of articles were published in bio-medicolegal journals (BML), of which 70.2% were in journals with IF (BML-IF). Articles published in BML-IF journals (33% of total papers) reach almost 50%, mainly in "Forensic Science International", "International Journal of Legal Medicine" and "Journal of Forensic Sciences". Instead, publications in not specifically bio-medicolegal journals (Not BML-IF) are greatly scattered and even fragmented in about 650 journals.The sub-disciplines that appear most frequently in Not BML-IF rather than BML-IF journals are Forensic Psychiatry (48.2% vs. 5.1%), Criminology (37.1% vs. 8.3%), Malpractice (50.7% vs. 4.0%), Medical Law and Ethics (46.4% vs. 6.9%) and Clinical Forensic Medicine (39.5% vs. 21.3%). The proposed bibliometric analysis revealed the preference of Forensic Pathology, Criminalistics (Biological), Forensic Genetics, Forensic Anthropology and Forensic Entomology for journals traditionally considered pertinent to the medico-legal discipline, with a considerable dispersion involving Toxicology, Psychiatry, Criminology and Malpractice, which were published in less well-known journals. This dispersion could be reduced adapting specialised forensic sections and increasing the IF of forensic journals, in order to respond suitably to the present demand for visibility by bio-medicolegal scientists, clearly oriented towards enhancing the objective impact of their curricula and attempting to attract funding to their research projects.

Analysis of suicide in the elderly in Italy. Risk factors and prevention of suicidal behavior.

The authors describe the nationwide scale of suicides among the elderly in Italy for the period 1993-2010. The data are derived from the Italian Institute for Statistics (ISTAT) and the World Health Organization (WHO). The elderly turned out to represent the highest risk category for suicide, with risk increasing with age (suicide rates, per 100,000, in men aged 75 or over and aged 65-74 were respectively 28.3 and 15.7 in 2007). The rates for men were three times higher than those for women. The north-east and north-west regions of Italy had the highest rates of suicide in the elderly. Education was inversely related to the risk of suicide. Hanging was the most frequent method of suicide in men, and precipitation in women. The reasons for suicide, as inferred from available data, were predominantly mental-physical illnesses. The risk factors emerging from our analysis are discussed from the preventive point of view, in relation to the Italian situation and a review of the literature.

Current practice in colonoscopy in the elderly.

Colonoscopy in the elderly is a reliable practice of great diagnostic and management value. However, patient's age has long been considered to affect the success of the procedure, achieved when the cecum is intubated, there is a good view of the colon if preparation has been properly carried out, and the examination does not cause excessive discomfort or complications. Substantial improvements have been made to the latter two aspects, due to more widespread use of deep sedation with propofol and cardiocirculatory monitoring during the procedure. The aim of our work was to assess whether, in the everyday practice of an open-access, digestive endoscopy teaching center, staffed by various providers delivering screening for polyposis, age is still a limitation to the success of the procedure and whether appropriate measures have been taken to improve colonoscopy in geriatric patients. We analysed 1480 consecutive colonoscopies, of which 319 were performed in patients aged over 73 years. The examination was significantly less successful in this group of patients (88.1 vs 94.4, p=0.0001), but there were no major technical or use-related complications connected with administration of propofol for sedation purposes, despite lower doses to the elderly (2.2 ± 1.1 mg/kg total dose, mean 151 ± 72.4 mg vs 2.9 ± 1.3 mg/kg total dose, mean 199 ± 77.9 mg in younger patients, p<0.001). More experienced technical staff were not allocated to these colonoscopies (for endoscopic or anesthesiological purposes) and, according to the results of multivariate stepwise logistic regression analysis, inadequate preparation was the main factor affecting the success of the procedure in elderly patients (OR 5.9, 95% CI 2.25-15.72; p=0.0003). Only body weight over 60 kg facilitated it (weight ≥ 60 kg, OR 0.46, 95% CI 0.26-0.83). In colonoscopy in the elderly, safety appears to be the primary concern and, good outcomes can be achieved, but sometimes at the expense of diagnostic accuracy. This could probably be improved through better pre- and post-procedure care, not currently differentiated between young and elderly patients.

N0 Stage colon cancer: prognostic role of age in relation to tumor site.

This work investigates the prognostic role of advanced age as a risk factor for recurrence in a population of patients undergoing surgery for N0 stage colon cancer, and also evaluates whether that role is affected by tumor location. A population of 129 consecutive patients who underwent radical surgery for N0 stage colon cancer was selected. Patients were subdivided into three age groups: <65, 65-80 and >80. The only correlation found in the examined population between age and clinical-pathological features was between advanced age (>80) and tumor location in the right side of the colon. Overall survival (OS) and disease- free survival (DFS) were significantly lower in patients over 80 than in the other two classes. Two multivariate analyses were carried out: when tumor location was not considered, age >80 represented a negative prognostic factor for risk of recurrence, regardless of the other factors examined. This role was also confirmed when tumor location was considered. As hypothesized by several authors, the role of advanced age which emerges from this study is mainly due to the increased fragility of elderly patients caused by multiple pathophysiological factors, but it does not necessarily represent an absolute contraindication to surgery. The role played by tumor location remains controversial, as more and more studies show that right colon cancer (RCC) is a biological entity distinct from left colon cancer (LCC). Further studies are required to examine right and left colon cancers as two separate diseases.

Choices in surgical treatment of diverticulitis.

Complications after surgical treatment of diverticulitis are not very frequent, in view of the total number of patients affected by this pathology, but they do become significant in absolute terms because of the high prevalence of the disease itself. Surgeons continue to debate which option is better: Hartmann resection or combined resection and anastomosis. Since age is a crucial factor when surgery is being considered, we evaluated the outcome of surgical treatment for diverticulitis in patients treated in our unit over a six-month period, in view of the number of elderly patients generally admitted. Between January 2001 and June 2012, 77 patients underwent surgery for diverticular disease in the Geriatric Surgery Unit of the Department of Surgical and Gastroenterological Sciences, University of Padova Hospital. Gastrointestinal resection and anastomosis were performed in 75 patients (97%), resulting in an overall complication rate of 37% and a mortality rate of 1%. This surgical strategy was chosen because, when it is performed by experienced surgeons, it offers the same results in terms of mortality and morbidity as Hartmann resection, while presenting significant advantages as regards the patient's quality of life. Various factors such as the timing of surgery, severity of the disease defined according to the Hinchey classification, patient's clinical condition, and surgeon's experience and expertise can all influence the surgical choice. Several studies in the literature confirm that combined resection and anastomosis is safe and efficacious, but more research is needed to confirm these data.

Diagnosis of chronic mesenteric ischemia in older patients: a structured review.

BACKGROUND AND AIMS: Chronic mesenteric ischemia in older patients is a challenge for the physician because it coincides with a vague and non-specific clinical presentation with abdominal pain. It can frequently cause diagnostic errors and lead to legal consequences. The aim of this work was to evaluate the literature on chronic mesenteric ischemia and focus on the limited data concerning the geriatric population. METHODS: This research focused on observational studies, randomized controlled trials, and clinical reports (excluding case reports and reviews) dealing with patients at least 65 years old with a clinical or instrumental diagnosis of chronic intestinal ischemia, published between 2000 and 2010. The search was conducted in PubMed using the following key words: chronic ischemic splanchnic disease, chronic mesenteric ischemia, angina abdominis, chronic abdominal angina, intestinal ischemia. RESULTS: We selected 925 articles with the key words as follows: chronic mesenteric ischemia in 355 cases; chronic ischemic splanchnic disease in 46; angina abdominis in 4; abdominal angina in 242; and chronic intestinal ischemia in 278. We then excluded articles judged scarcely pertinent, case reports, reviews, works concentrating only on diagnostic, methodological, instrumental and surgical approaches, and articles based on animal or experimental models. This selection left us with 13 articles (after excluding duplicates), only three of which were considered valid for our purposes. CONCLUSIONS: Our review indicates that there is a shortage of useful literature on chronic intestinal ischemic disease diagnosed in the older adults, and the appropriate geriatric management of these patients is consequently not well established.

Clinical correlation of mesenteric vascular disease in older patients.

Mesenteric vascular obstruction is difficult to characterize, since it may produce differing acute or chronic clinical pictures and various organic symptoms, such as ischemic colitis and abdominal angina. The diagnosis of chronic mesenteric ischemia (CMI) is thus still mainly based on historic diagnostic criteria drawn up before non-invasive radiological imaging of the mesenteric vessels became widespread, and before the current demographic developments leading to a rise in the number of older patients with multiple pathologies. With this premise, we studied the clinical condition of 85 patients aged over 65 years of age, submitted to angio-CT scan for reasons other than neoplastic and general pathologies which may cause alterations in mesenteric blood flow, and without the typical symptoms of acute intestinal ischemia. Of these, 34 patients presented occlusion of at least one mesenteric vessel and 13 were affected by multivessel injury. Compared with controls, patients with mesenteric artery disease had lower BMI (24.9+/-3.3 vs 26.8+/-4.5) and longer hospital stays (14 vs 6 days), and were more frequently affected by vasculopathies in other districts (97.1% vs 80.4%), but the only bowel symptom present was diarrhea (21.2% vs 5.9%). These patients also took more benzodiazepines and acetylsalicylic acid. The results of stepwise logistic analysis of length of hospital stay, vasculopathies, diarrhea, and use of benzodiazepines yielded a predictive model with an AUC (area under the curve) of 0.81. Our data show that some features characterizing CMI in the geriatric population differ from those of the general population.

Statins and the elderly: recent evidence and current indications.

Cardiovascular disease (CVD) is estimated to remain as the main cause of death in developed nations over the next 30 years, with increased prevalence in the older population. This is because the observed decline in the incidence of CVD owing to improvements in prevention has now been counterbalanced by the increased shift toward an older and thus more fragile population. Statin treatment reduces cardiovascular morbidity and mortality in middle-aged adults. However, few studies have included older individuals, particularly those aged 80 years or over. The adverse effects associated with high doses of statins and their interactions with other drugs may give rise to more problems in the elderly population. Evidence remains limited regarding the overall benefit of starting statin therapy in adults aged 80 and over; so that clinical judgment remains necessary in making the decision to use them. In this review, we present available evidence from randomized clinical trials, as well as relative community and post-approval data directly applicable to the management of CVD in the elderly, in both primary and secondary prevention. Also discussed is the latest evidence regarding the putative protective effects of statins on senile dementia and the relationship between statin treatment and cancer.
