L’accuratezza del Registro Mesoteliomi Lombardia: comparazione con il database autoptico dell’Università di Pavia|Accuracy of the Lombardy Mesothelioma Registry: comparison with the autopsy database of Pavia University (Lombardy Region, Northern Italy)
OBJECTIVES: to evaluate the accuracy (completeness of case recording and diagnostic quality) of the Lombardy Mesothelioma Registry (Registro Mesoteliomi Lombardia, RML) through a comparison with the autopsy database of Pavia University (years 2000-2016). DESIGN: validation study. SETTING AND PARTICIPANTS: all mesothelioma records with incidence date between 01.01.2000 and 16.09.2016 were extracted from the RML. They were cross-referenced with deaths from any asbestos-related disease subjected to a forensic autopsy extracted from the archive of the Department of Public Health, Experimental and Forensic Medicine of Pavia University. MAIN OUTCOMES MEASURES: using the postmortem diagnosis by Pavia University as the gold standard, RML sensitivity and specificity and their 95% confidence intervals (95%CI) were calculated using the Agresti-Coull formula. RESULTS: based on 141 deaths, the RML showed very good accuracy: specificity was 100% (95%CI 87%-100%; 32/32 deaths) and sensitivity 94% (95%CI 87%-97%; 102/109 deaths). The 7 false negative cases either were missed by the RML (N. 4) or had been wrongly classified as non-mesotheliomas (N. 3) because the diagnosis was made or confirmed only postmortem after a forensic autopsy. CONCLUSIONS: RML accuracy (completeness and diagnostic quality) was very high. No false positive was found and the few false negatives were due to lack of notification of mesotheliomas diagnosed postmortem to the registry. Forensic pathologists should be made aware that mesothelioma notification to the regional mesothelioma registry is important and compulsory
A case of intrauterine fetal death related to furcate cord insertion: a brief review of the literature and professional liability considerations
The furcate insertion of the umbilical cord is an uncommon abnormality, often asymptomatic, potentially dangerous, or lethal for the fetus and the mother. This report shows the case of a healthy 29-year-old patient, at 37 weeks of gestation, admitted to the hospital two days before the due date because of the appearance of uterine contractions; clinical exams were regular. The following day, no fetal movements were perceived, a cardiotocography was performed, showing the absence of fetal heartbeat. A dead fetus was delivered. Autopsy showed furcate insertion of the umbilical cord and the rupture of the umbilical vessel, which caused fetal hemorrhagic shock. Furcate insertion still remains mostly undiagnosed and rarely it can be identified prenatally (only three cases are reported in literature). Future research, mainly in forensic fields, could improve the knowledge about this condition, helping prenatal diagnosis and providing warnings that can prevent similar deaths in the future
Drug abuse-related neuroinflammation in human postmortem brains: An immunohistochemical approach
Going Beyond Counting First Authors in Author Co-citation Analysis
The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
New insights on fibrodysplasia ossificans progressiva: Discussion of an autoptic case report and brief literature review
Fibrodysplasia ossificans progressiva (FOP) is a rare genetic condition with soft tissue progressive ossification, leading to severe disability. We describe a 27-years-old female affected by FOP who died after a fall. An autopsy was performed. Upper and lower extremities resulted in fixed flexion, with kyphoscoliosis of the spine and chest wall deformity. Moreover, a cranial fracture was pointed out. At histology, atypical abundance of corpora amylacea in gray matter was observed. In a sample of macroscopically non-affected muscular tissue, small areas with necrosis of myocytes and hyperplasia of fibroblasts were seen in light microscopy, with intracellular inorganic dystrophic inclusions in transmission electron microscopy. Thyroid gland histology showed diffuse lymphocytic infiltration. Postmortem examination of FOP patients provided precious information about involvement of other tissues, suggesting an initial and widespread inflammatory/dystrophic phase, to be further investigated, because it might reveal new insights about a FOP mutation cascade
Genetic individual identification from dried urine spots: A complementary tool to drug monitoring and anti-doping testing
The collection of liquid biological matrices onto paper cards (dried matrix spots [DMS]) is becoming an alternative sampling strategy. The stability over time of molecules of interest for therapeutic, sport drug monitoring, and forensic toxicology on DMS has been recently investigated representing a reliable alternative to conventional analytical techniques. When a tampering of a urine sample in drug monitoring or doping control cases is suspected, it could be relevant to know whether genetic profiles useful for individual identification could be generated from urine samples spotted onto paper (dried urine spot [DUS]). To understand the influence of sex, storage conditions, and time on the quality and quantity of the DNA, five female and ten male urine samples were dispensed onto Whatman 903 paper and sampled after different storage conditions over time, from 1 to 12 weeks. Direct PCR was performed starting from 2-mm punches collected from each spot amplifying a panel of markers useful for individual identification. The female DUS stored in different conditions produced genetic profiles fully matching the reference samples. The same result was obtained for the male DUS but using urine 30X concentrated by centrifugation instead of the original samples. Our data show that this approach is valid for genetic individual identification of urine samples spotted onto paper cards up to 12 weeks after deposition and could be easily incorporated in anti-doping or drug screening protocols to help on the suspicion of evidence tampering or to solve questions on the reliability of samples collection
