Nishio T, Toukairin Y, Hoshi T, Arai T, Nogami M. Relationships between cause of death and concentrations of seven steroids obtained from the serum and cerebrospinal fluid of cadavers. J Forensic Leg Med 2023; 96:102516. [PMID: 37011448 DOI: 10.1016/j.jflm.2023.102516] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2022] [Revised: 03/04/2023] [Accepted: 03/25/2023] [Indexed: 03/30/2023]
Abstract
In this study, we assessed 80 autopsy samples to investigate the relationships between cause of death and the concentrations of multiple steroids in serum and cerebrospinal fluid (CSF). First, we developed and validated analytical methods to quantify seven steroids (cortisol, cortisone, corticosterone, 11-deoxycortisol, 11-deoxycortiocosterone, progesterone, and testosterone) by using liquid chromatography coupled with electrospray ionization-tandem mass spectrometry. Next, we statistically evaluated the levels of each steroid for six causes of death: hypothermia, traumatic injury, fire fatality, asphyxia, intoxication, and internal disease. We observed that cortisol concentrations in serum and CSF obtained from cadavers who died from hypothermia were significantly higher than those in samples obtained from cadavers who died from the remaining causes of death (P < 0.05). Similarly, corticosterone concentrations obtained from cadavers who died from hypothermia were significantly higher than those in samples from several other causes of death. However, concentrations of the remaining steroids analyzed did not differ significantly among the causes of death. We further elucidated the correlations between steroid concentrations in serum and CSF. Except for 11-deoxycorticosterone and progesterone, steroid concentrations were significantly positively correlated in serum and CSF. Although data on cadaveric steroid concentrations are limited-especially in CSF-values obtained were in the approximate range of the living human data reported to date.

Absence of Stress Hyperglycemia Indicates the Most Severe Form of Blunt Liver Trauma. Diagnostics (Basel) 2021; 11:diagnostics11091667. [PMID: 34574008 PMCID: PMC8470453 DOI: 10.3390/diagnostics11091667] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2021] [Revised: 08/24/2021] [Accepted: 09/08/2021] [Indexed: 01/08/2023] Open
Abstract
Background: Stress hyperglycemia is common in trauma patients. Increasing injury severity and hemorrhage trigger hepatic gluconeogenesis, glycogenolysis, peripheral and hepatic insulin resistance. Consequently, we expect glucose levels to rise with injury severity in liver, kidney and spleen injuries. In contrast, we hypothesized that in the most severe form of blunt liver injury, stress hyperglycemia may be absent despite critical injury and hemorrhage. Methods: All patients with documented liver, kidney or spleen injuries, treated at a university hospital between 2000 and 2020 were charted. Demographic, laboratory, radiological, surgical and other data were analyzed. Results: A total of 772 patients were included. In liver (n = 456), spleen (n = 375) and kidney (n = 152) trauma, an increase in injury severity past moderate to severe (according to the American Association for the Surgery of Trauma, AAST III-IV) was associated with a concomitant rise in blood glucose levels independent of the affected organ. While stress-induced hyperglycemia was even more pronounced in the most severe forms (AAST V) of spleen (median 10.7 mmol/L, p < 0.0001) and kidney injuries (median 10.6 mmol/L, p = 0.004), it was absent in AAST V liver injuries, where median blood glucose level even fell (5.6 mmol/L, p < 0.0001). Conclusions: Absence of stress hyperglycemia on hospital admission could be a sign of most severe liver injury (AAST V). Blood glucose should be considered an additional diagnostic criterion for grading liver injury.

The Vital Role of Thanatochemistry in the Postmortem Diagnostic of Diabetic Ketoacidosis-Case Report. Diagnostics (Basel) 2021; 11:diagnostics11060988.

Abstract
Diabetic ketoacidosis (DKA) is a lethal acute hyperglycemic complication of diabetes mellitus (DM) and it represents the initial manifestation of DM in about 15-20% of cases in adults and about 30-40% of cases in children. Postmortem diagnosis of DKA can only be made by applying thanatochemistry. Biochemistry applied postmortem is viewed with skepticism by many practitioners in the forensic field, completely lacking in many forensic services around the world, and especially in the national ones. This article aims to underline the importance of the postmortem application of biochemistry by reviewing the case of a person in the third decade of life who died suddenly at home due to diabetic ketoacidosis (DKA), whose autopsy was performed at an early PMI of approximately 24 h. Routine postmortem examinations (macroscopic, anatomopathological, and toxicological) could not establish a clear cause of death. When attention was turned to biochemical determinations (i.e., determination of glycated hemoglobin, glucose and ketone bodies (acetone, beta-hydroxybutyrate) in the blood, vitreous humor, and cerebrospinal fluid), the identified values clarified the thanatogenic mechanisms by establishing the diagnosis of DKA.

Abstract
Hypothermia is an important cause of death in forensic pathology. For the forensic diagnosis of hypothermia, some reports point out the possibility that hypothermia without diabetes may cause ketoacidosis. In this study, we evaluated the diagnostic value of ketoacidosis in a murine model of hypothermia, using the cold stress at 4 °C for 3 or 5 hrs in genetically diabetic (BKS.Cg-+Leprdb/+Leprdb/J) mice, compared with control (BKS.Cg- Dock7m+/Dock7m+/J) mice. The core temperature decrease was larger in diabetic mice than in control mice. We observed a novel finding that ketoacidosis assessed by elevated serum 3-hydroxybutyrate (3HB) occurs in hypothermia both in diabetic and control mice. Diabetic mice showed a prominent elevation of serum 3HB under cold stress. The protein expressions of monocarboxylate cotransporter 1 (MCT1), the channel protein used for the uptake of 3HB in skeletal muscles, showed a statistically significant decrease under cold stress for 3 hrs in control mice, indicating that the serum 3HB increase may be partially due to the decrease in the cellular uptake through the channel protein. Our results suggest the usefulness of hyperketonemia for the diagnosis of hypothermia not only in diabetic but also in non-diabetic cases.

Abstract
Acute stomach disease in elderly patients often lacks characteristic clinical manifestations. Presentations may differ from those in younger patients and are often complicated by concomitant diseases, delayed presentation, and misdiagnosis. Incorrect diagnosis and treatment can lead to medical-related death claims. We investigated eight cases of elderly fatality due to acute abdominal diseases in forensic autopsy cases. Although most fatalities were unwitnessed, possibly due to the characteristics of elderly individuals, recent social backgrounds, and involvement with health care, some cases of possible misdiagnosis suggested that physicians should carefully consider atypical clinical manifestations and the characteristics of elderly individuals when the managing abdominal symptoms, particularly in primary health care. Our investigation of these forensic autopsy cases indicated the particular importance of peritoneal adhesions as an unexpected cause of acute abdomen in the elderly due to strangulation ileus, even among those with no history of abdominal surgery or trauma. Diagnosis of acute stomach symptoms can be difficult in elderly patients. Pathophysiological examination and autopsy analyses can thus contribute to early-stage diagnosis and prevention of acute stomach symptoms in elderly patient populations.

Abstract
Currently, brain natriuretic peptide (BNP) and N-terminal proBNP (NT-proBNP) are widely used as diagnostic biomarkers for heart failure (HF) and cardiac dysfunction in clinical medicine. They are also used as postmortem biomarkers reflecting cardiac function of the deceased before death in forensic medicine. Several previous studies have reviewed BNP and NT-proBNP in clinical medicine, however, few articles have reviewed their application in forensic medicine. The present article reviews the biological features, the research and application status, and the future research prospects of BNP and NT-proBNP in both clinical medicine and forensic medicine, thereby providing valuable assistance for clinicians and forensic pathologists.

Kjærulff MLBG, Astrup BS. Sudden death due to diabetic ketoacidosis following power failure of an insulin pump: Autopsy and pump data. J Forensic Leg Med 2019; 63:34-39. [PMID: 30856551 DOI: 10.1016/j.jflm.2019.02.013] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2018] [Revised: 02/11/2019] [Accepted: 02/22/2019] [Indexed: 02/05/2023]
Abstract
PURPOSE To report a case in which autopsy findings and data from an insulin pump illustrate the course up to the death of a 31-year-old man with a history of type 1 diabetes mellitus who was found dead in his apartment with his insulin pump disassembled and placed in another room. METHODS Autopsy findings including histological, toxicological and biochemical examination are presented. Postmortem download of data from the insulin pump gave the history of the pump, which included blood glucose, insulin bolus, carbohydrate intake and the time course in the days to death, and the pump settings were recorded. For this case report, police reports on the death as well as hospital records were also reviewed. RESULTS At the patch for the insulin pump, nothing abnormal was found. Biochemical analysis showed glucose of 35 mmoL/L in vitreous humor fluid indicating antemortem hyperglycemia, and ketone bodies in the blood of 11.0 mmoL/L indicating ketoacidosis. Acute pulmonary hemostasis, chronic fat accumulation in the liver and acute fat accumulation in the kidneys were histological detected. There were no signs of late diabetic complications such as nephropathy or cardiovascular disease in the tissues. Insulin pump data showed that after three alarms, a power failure of the pump occurred leading to discontinuing insulin delivery, and about 48 h before the deceased was found dead, his body was depleted of insulin. CONCLUSION The cause of death is believed to be diabetic ketoacidosis due to completely lack of insulin because of power failure of the insulin pump, which therefore has been a decisive factor in the cascade of events that led to death. The case is, to our knowledge, the first to illustrate a death caused by diabetic ketoacidosis which is supported by autopsy findings and by data of an insulin pump up to the time of power failure. It is a strong example of usefulness of postmortem download of data from insulin pumps to help determine the cause of death among diabetics. Forensic pathologists should therefore review data and history of the pump systematically.

Abstract
The study was conducted at the Estonian Forensic Science Institute in 2008–2014 as continuous part of our previous study of alcohol and premature death in Estonian men. Autopsy data from 504 cases of male deaths (ages 19–79) were collected and blood and urine samples for glycated haemoglobin (HbA1c), liver enzymes and alcohol concentration were analysed. The aim of our research was to find undiagnosed diabetes and diabetes risk cases postmortem on the basis of increased values of HbA1c. HbA1c was within the reference value 4.8%–5.9% (29–42 mmol/mol), in 88.1% (n = 444) of cases, below reference value in 2.4% (n = 12), in the risk group of diabetes, HbA1c 6.0%–6.4% (42–46 mmol/mol) was within 5.8% (n = 29), and HbA1c result of ≥6.5% (48 mmol/mol) manifested in 3.8% (n = 19) of cases. The higher the age, the more cases with HbA1c value ≥6.0% (42 mmol/mol) occurred. In the group of external causes of death (n = 348), the HbA1c value of ≥6.5% (48 mmol/mol) HbA1c occurred in four cases. The HbA1c value was ≥6.5% (48 mmol/mol) in 78.9% of 156 cases when the cause of death was disease, of which 58% were cardiovascular diseases. The prevalence of diabetes and diabetes risk was found lower compared to population-based study, as majority of the deceased were young and middle-aged males and no females were included. In the case of poisoning with narcotic substances, HbA1c was within the reference range. A negative correlation occurred between alcohol intoxication and HbA1c value. A positive correlation between ALT and HbA1c was found – the higher stage of liver damage correlated with the higher HbA1c level.

Abstract
Oral antidiabetics can cause fatal hypoglycemia; although they can be chemically identified and quantified, biochemical investigations are important for assessing the biological consequences of an overdose. Such cases of overdose involving oral antidiabetics may involve other drugs for treating lifestyle-related diseases, particularly antihypertensives. Here, we report a toxicological and biochemical investigation of drugs and biochemical profiles in a fatal overdose involving multiple oral antidiabetics and antihypertensives. A 55-year-old woman died about 2 days after the ingestion of around 110 tablets of antidiabetics and antihypertensives that had been prescribed for her husband. A forensic autopsy and histological analysis demonstrated no evident pathology as the cause of death. A toxicological analysis suggested hypoglycemia and an overdose of antihypertensives as well as the retention of antidiabetics and diuretics in the pericardial fluid. A relatively low pericardial amlodipine concentration was observed, which may have been the result of its long half-life (slower distribution and reduction rate) and/or possible affinity with the myocardium. In addition, a biochemical analysis indicated hypoglycemia, without increased serum insulin and C-peptide, but with increased glucagon levels, as the possible influence of glibenclamide overdose. These observations suggest the usefulness of a combination of toxicological and biochemical analyses in postmortem investigations involving a fatal overdose of such drugs.

Abstract
Background Deranged glucose metabolism is frequently observed in trauma patients after moderate to severe traumatic injury, but little data is available about pre-hospital blood glucose and its association with various cardiac rhythms and cardiac arrest following trauma. Methods We retrospectively investigated adult trauma patients treated by a nationwide helicopter emergency medical service (34 bases) between 2005 and 2013. All patients with recorded initial cardiac rhythms and blood glucose levels were enrolled. Blood glucose concentrations were categorised; descriptive and regression analyses were performed. Results In total, 18,879 patients were included, of whom 185 (1.0%) patients died on scene. Patients with tachycardia (≥100/min, 7.0 ± 2.4 mmol/L p < 0.0001), pulseless ventricular tachycardia (9.8 ± 1.8, mmol/L, p = 0.008) and those with ventricular fibrillation (9.0 ± 3.2 mmol/L, p < 0.0001) had significantly higher blood glucose concentrations than did patients with normal sinus rhythm between 61 and 99/min (6.7 ± 2.1 mmol/L). In patients with low (≤2.8 mmol/L, 7/79; 8.9%, p < 0.0001) and high (> 10.0 mmol/L, 70/1271; 5.5%, p < 0.0001) blood glucose concentrations cardiac arrest was more common than in normoglycaemic patients (166/9433, 1.8%). ROSC was more frequently achieved in hyperglycaemic (> 10 mmol/L; 47/69; 68.1%) than in hypoglycaemic (≤4.2 mmol/L; 13/31; 41.9%) trauma patients (p = 0.01). Conclusions In adult trauma patients, pre-hospital higher blood glucose levels were related to tachycardic and shockable rhythms. Cardiac arrest was more frequently observed in hypoglycaemic and hyperglycaemic pre-hospital trauma patients. The rate of ROSC rose significantly with rising blood glucose concentration. Blood glucose measurements in addition to common vital parameters (GCS, heart rate, blood pressure, breathing frequency) may help identify patients at risk for cardiopulmonary arrest and dysrhythmias.

BACKGROUND Individuals who suffer from mental illness are more prone to obesity and related co-morbidities, including the metabolic syndrome. Autopsies provide an outstanding platform for the macroscopic, microscopic and molecular-biological investigation of diseases. Autopsy-based findings may assist in the investigation of the metabolic syndrome. To utilise the vast information that an autopsy encompasses to elucidate the pathophysiology behind the syndrome further, we aimed to both develop and evaluate a method for the post mortem definition of the metabolic syndrome. METHODS Based on the nationwide Danish SURVIVE study of deceased mentally ill, we established a set of post mortem criteria for each of the harmonized criteria of the metabolic syndrome. We based the post mortem (PM) evaluation on information from the police reports and the data collected at autopsy, such as anthropometric measurements and biochemical and toxicological analyses (PM information). We compared our PM evaluation with the data from the Danish health registries [ante mortem (AM) information, considered the gold standard] from each individual. RESULTS The study included 443 deceased individuals (272 male and 171 female) with a mean age of 50.4 (± 15.5) years and a median (interquartile range) post mortem interval of 114 (84-156) hours. We found no significant difference when defining the metabolic syndrome from the PM information in comparison to the AM information (P = 0.175). The PM evaluation yielded a high specificity (0.93) and a moderate sensitivity (0.63) with a moderate level of agreement compared to the AM evaluation (Cohen's κ = 0.51). Neither age nor post mortem interval affected the final results. CONCLUSIONS Our model of a PM definition of the metabolic syndrome proved reliable when compared to the AM information. We believe that an appropriate estimate of the prevalence of the metabolic syndrome can be established post mortem. However, while neither the PM nor the AM information is exhaustive in terms of defining an individual's health status, a superlative estimate may be obtained by combining the PM and the AM information. With this model, we open up the possibility of utilising autopsy data for future studies of the metabolic syndrome.

Usefulness of postmortem biochemistry in identification of ketosis: Diagnosis of ketoacidosis at the onset of autoimmune type 1 diabetes in an autopsy case with cold exposure and malnutrition. Leg Med (Tokyo) 2016; 22:23-9. [PMID: 27591535 DOI: 10.1016/j.legalmed.2016.07.006] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/12/2016] [Revised: 07/04/2016] [Accepted: 07/25/2016] [Indexed: 10/21/2022]
Abstract
A severely malnourished, Japanese female in her twenties was found dead in her apartment. On autopsy, most of the findings from the internal examination were suggestive of hypothermia. Postmortem biochemistry, however, showed severely increased levels of glycated hemoglobin (HbA1c) and blood and urine glucose levels. Levels of acetone, 3-hydroxybutyric acid, and acetoacetate in various body fluids were also highly increased, indicating ketosis. The serum insulin and c-peptide levels were severely low, and subsequent testing was positive for anti-GAD antibodies. Immunohistochemical examination of the pancreatic islet cells revealed few insulin-positive cells but many glucagon-positive cells on staining. Furthermore, slight invasion of CD8-positive lymphocytes in the pancreatic islets of Langerhans was observed. Results of immunostaining of the pancreatic and bronchial epithelial tissues were partly positive for the Influenza A virus. We concluded that severe ketoacidosis associated with rapid-onset hyperglycemia due to autoimmune type 1 diabetes (AT1D) had occurred shortly before death. However, the ketosis was accompanied by hypothermia and malnutrition as well as diabetic ketoacidosis (DKA). Therefore, we retrospectively collected biochemical data on cases of hypothermia and malnutrition and compared them with the present case. Serum glucose, acetone, 3-hydroxybutyric acid, and acetoacetic acid can be used for screening and diagnosis to distinguish DKA from ketosis due to hypothermia and malnutrition. Therefore, in the present case, we diagnosed that the natural cause of death was due to AT1D. In conclusion, screening investigations for relevant biochemical markers can provide essential information for the diagnosis of metabolic disturbances, which fail to demonstrate characteristic autopsy findings.
