RESUMO

OBJECTIVE: Age estimation of living or dead individuals has a strategic importance in medicine, anthropology, and forensic science, in the context of mass disasters and in civil or criminal matters such as adoption or asylum. Teeth play a major role in this context in particular, the third molars are useful for determining whether an individual has reached the legal age of 18 years because they are still in development from the age of 14. MATERIALS AND METHODS: In this study, a sample of 307 panoramic radiographs performed on healthy subjects aged between 13 and 23 was analyzed to consider the correlation between the maturity index of the third molar (I3M) and age to verify the reliability of the cutoff 0.08 indicated by Cameriere et al in a sample of Italian subjects living in the Province of Messina (Sicily, South Italy) to discern the adult subjects from the minors. STATISTICAL ANALYSIS: The analysis of 307 panoramic radiographs resulted in a sensitivity of 89.2% with a confidence interval of 95%, a specificity of 96.5% with a confidence interval of 95%, and a positive predictive value of 96.7%. RESULTS: The method proved itself reliable in estimating adulthood in the population of the Messina- Sicily, but the I3M should not be used as the sole indicator to determine whether a person is younger or older than 18 years because age estimation based on dental methods alone has limitations as the third molars suffer from many variations related to their morphology, their location, and their development. CONCLUSION: We recommend a combination of several methods that are available to increase accuracy of age estimation, depending on the different legal requirements in civil or criminal cases.

RESUMO

Hypericum is a widely present plant, and extracts of its leaves, flowers, and aerial elements have been employed for many years as therapeutic cures for depression, skin wounds, and respiratory and inflammatory disorders. Hypericum also displays an ample variety of other biological actions, such as hypotensive, analgesic, anti-infective, anti-oxidant, and spasmolytic abilities. However, recent investigations highlighted that this species could be advantageous for the cure of other pathological situations, such as trigeminal neuralgia, as well as in the treatment of cancer. This review focuses on the in vitro and in vivo antitumor effects of St. John's Wort (Hypericum perforatum), its derivatives, and other Hypericum species in hematologic malignancies. Hypericum induces apoptosis in both myeloid and lymphoid cells. Other Hypericum targets include matrix metalloproteinase-2, vascular endothelial growth factor, and matrix metalloproteinase-9, which are mediators of cell migration and angiogenesis. Hypericum also downregulates the expression of proteins that are involved in the resistance of leukemia cells to chemotherapeutic agents. Finally, Hypericum and its derivatives appear to have photodynamic effects and are candidates for applications in tumor photodynamic therapy. Although the in vitro studies appear promising, controlled in vivo studies are necessary before we can hypothesize the introduction of Hypericum and its derivatives into clinical practice for the treatment of hematologic malignancies.

RESUMO

Diagnosis of death by electrocution may be difficult when electric marking is not visible or unclear. Accordingly, the body of a man who appeared to have died from accidental electrocution was carefully forensically analysed. Macroscopic and microscopic analysis of the current mark was carried out using a variable-pressure scanning electron microscope equipped with energy dispersive X-ray microanalyser to highlight skin metallisation, indicating the presence of iron and zinc. The histological findings of electrocution myocardial damage were supported by the results of biochemical analysis which demonstrated the creatine kinase-MB and cardiac troponin I elevation. The effects of electric current flow were also highlighted by perforations of endothelial surface of a pulmonary artery using scanning electron microscope, and all the results were analysed by the main tools suggested in the literature.

RESUMO

BACKGROUND: Gamma-hydroxybutyrate (GHB or sodium oxybate) is both an exogenous and endogenous molecule with neuromodulator properties. In the United States, GHB is an approved drug for the treatment of narcolepsy and narcolepsy with cataplexy in adults. In some European Union countries, sodium oxybate is applied for the treatment of opioid and alcohol withdrawal. OBJECTIVE: The aim of the present review was to describe the state of art of the pre-clinical research and the clinical evidence related to GHB used alone or in combination with other treatments in alcohol withdrawal syndrome and alcohol abstinence maintenance. METHOD: Internationally published pre-clinical findings and clinical studies investigating the effects of GHB on alcohol withdrawal syndrome and alcohol abstinence maintenance were collected and described considering seven clinical studies involving GHB in the treatment of alcohol withdrawal abstinence and five clinical studies involving GHB in the treatment of alcohol abstinence maintenance. Furthermore, GHB pharmacology and characteristics of abuse were briefly detailed. RESULTS: Clinical evidence indicates that GHB is effective in reducing symptoms of alcohol withdrawal syndrome and produces beneficial effects comparable to those of benzodiazepines or chlometiazole. GHB proved effective in increasing alcohol abstinence maintenance and in reducing alcohol craving, but it did not show any influence in relapses of heavy drinkers when given alone. Conversely, it seems to be effective in reducing relapses in alcohol dependent patients when given in combination with naltrexone and escitalopram. CONCLUSION: Despite this bunch of evidence, studies are still limited and investigations including a larger number of patients are needed. In addition, some safety concerns, such as insufficiency against hallucinations in alcohol withdrawal and potential development of GHB dependence have to be more investigated.

RESUMO

The differential diagnosis of vasculitis is often a difficult task due to the frequent morphological similarities that various vasculitic syndromes express when the heart is the target organ. The more the lesions are limited to the arterial tree with absent or almost silent coronary events, the less specific the anatomical and clinical frameworks. To create a series of clinical records and on the basis of these assumptions, the authors report a case concerning the sudden death of a 43-year-old woman which occurred while an ergonometric test was being carried out 28 days after the onset of the symptoms. A subsequent postmortem investigation/autopsy enabled us to detect a granulomatous aortitis process and, in particular, a coronary ostial stenosis and severe involvement of the coronary vessels which was compatible with the pathological framework of Takayasu disease.

RESUMO

Materials used for dental impressions are usually safe. This study describes a case of fatal anaphylaxis that appeared immediately after the oral mucosa came into contact with an alginate paste used for dental impressions. The cadaveric examination and the postmortem toxicology report confirmed that the cause of death was anaphylactic shock. The patient was affected by both cardiovascular and lung diseases that worsened the condition and forbade the use of epinephrine. To the authors' knowledge, dental impression materials, and alginate in particular, have not been reported previously as being a cause of anaphylaxis.
