Fatal postpartum spontaneous liver rupture: case report and literature review

Maternal hepatic rupture is a rare complication of pregnancy that can be fatal to both mother and child. This phenomenon is most often associated with preeclampsia/eclampsia and/or HELLP syndrome, which is defined by a collection of clinical features including hemolysis (H), elevated liver enzymes (EL), and a low platelet count (LP). These disease processes are typically identified and treated during pregnancy, often in the last trimester. The described case is unusual in that the decedent had no known history of preeclampsia/eclampsia or HELLP syndrome during this pregnancy, and she died suddenly several days postpartum of liver rupture with massive intraperitoneal hemorrhage following a routine cesarean section delivery and an uneventful hospital course. Similar cases are infrequent in the literature, which is reviewed in this report.     

Fatal rupture of hepatic adenomatosis: Autopsy case and review of the literature

Hepatic adenomatosis is a rare disease consisting of multiple adenomas in otherwise-normal liver parenchyma. Though the discovery of this entity goes back several years, its diagnosis is still challenging in terms of its definition and pathophysiology. Clinically, patients may be completely asymptomatic and the diagnosis is only made incidentally through imaging tests. The discovery could be made when complications occur such as intraperitoneal hemorrhage with hypovolemic shock due to the rupture of an adenoma. We report a fatal case of a ruptured adenoma in a case of hepatic adenomatosis discovered at autopsy. In order to achieve a better view of this disease, we conducted a literature review on this subject describing the pathogenesis, manifestations, and autopsy contribution to addressing this entity.     

Fatal strychnine poisoning--a case report and review of the literature

A typical case of suicidal strychnine poisoning by a rodenticide is presented. The forceful muscular convulsions were accompanied by a clear sensorium. Pathological findings consisted of an early onset of postmortem rigidity and microscopic hemorrhages with minimal degenerative neuronal changes in the spinal cord. The highest tissue concentrations of strychnine were found in the bile and liver. The pathophysiology and epidemiology of strychnine poisoning is reviewed and discussed in context.     

Fatal bilateral pneumothoraces after electroacupuncture treatment: A case report and literature review

Acupuncture is practiced as a complementary medicine worldwide. Although it is considered a safe practice, pneumothorax is one of its most common serious complications. However, there have been few reports of deaths due to pneumothorax after acupuncture treatment, especially focused on electroacupuncture. We report an autopsy case of a man in his 60s who went into cardiopulmonary arrest and died immediately after receiving electroacupuncture. Postmortem computed tomography (PMCT) showed bilateral pneumothoraces, as well as the presence of numerous gold threads embedded subcutaneously. An autopsy revealed two ecchymoses in the right thoracic cavity and a pinhole injury on the lower lobe of the right lung, suggesting that the needles had penetrated the lung. There were marked emphysematous changes in the lung, suggesting that rupture of bullae might also have contributed to bilateral pneumothoraces and fatal outcome. The acupuncture needles may have been drawn deeper into the body than at the time of insertion due to electrical pulses and muscle contraction, indicating the need for careful determination of treatment indications and technical safety measures, such as fail-safe mechanisms. This is the first case report of fatal bilateral pneumothoraces after electroacupuncture reported in the English literature. This case sheds light on the safety of electroacupuncture and the need for special care when administering it to patients with pulmonary disease who may be at a higher risk of pneumothorax. This is also the first report of three-dimensional reconstructed PMCT images showing the whole-body distribution of embedded gold acupuncture threads, which is unusual.     

Fatal intoxication due to tramadol alone: case report and review of the literature

Poisoning may also lead to both coma and multiple organ failure, also in youngsters without a known major medical history. As not all toxic agents are routinely screened when a poisoning is suspected, it is useful to consider less frequently encountered poisons in certain cases. We describe the occurrence of asystole and multiple organ failure which occurred in a young man after a suspected tramadol overdose. The tramadol concentration on admission in the ICU was indeed 8 microg/ml (mg/l), far above the therapeutic range. Subsequently, the patient developed severe acute liver failure, finally leading to death. Post-mortem toxicology did not reveal any other poison responsible for this unfavourable course as only very high serum and tissue tramadol and desmethyltramadol concentrations were found. Only a few fatal poisonings attributable to tramadol alone, as observed in our case, have been reported. An overview of these cases is presented.     

Fatal brown bear (Ursus arctos) attack: case report and literature review

Bear incidents are widely publicized, though serious incidents rarely occur. We describe here a case of human death caused by brown bear (Ursus arctos) feet. The brown bear is the biggest carnivore of Greece, reaching up to 200-300 kg weight.This is the first documented fatality involving a brown bear in Greece in which the victim died as a direct traumatic result of the attack.     

Fatal neurotoxic response to neuroleptic medications: case report and review of the literature

Neuroleptic malignant syndrome (NMS) is a diagnosis of exclusion difficult to make due to a lack of pathognomonic features. Diagnosing NMS by postmortem examination becomes increasingly challenging when possible underlying brain pathology is obscured. The diagnosis is based on clinical history and laboratory findings. Autopsy and histologic findings, if any, usually are reflective of hyperthermia or complications (eg, aspiration pneumonia) of NMS. The authors describe a case of a 36-year-old Hispanic woman with a presumptive diagnosis of pseudoseizures, treated with various combinations of neuroleptic medications over a 6-week period prior to her sudden, unexpected, in-hospital death. Neuroleptic malignant syndrome is likely to have contributed to this patient's death. Confounding factors and medicolegal issues of a postmortem diagnosis of NMS are discussed.     

Heimlich trauma: a violent maneuver.

The Heimlich maneuver is a life-saving technique for dislodging foreign material from the respiratory tract. This report illustrates intraabdominal injuries, including a large mesenteric laceration, mesenteric contusions, and intraperitoneal hemorrhage, that occurred in a recipient of a vigorously applied Heimlich maneuver. The potential for confusing such injuries with homicidally inflicted injuries is emphasized.     

Fatal birth trauma due to an undiagnosed abdominal teratoma: case report and review of the literature

The fetus is subjected to mechanical forces during labor and delivery, which may result in traumatic injuries. Such injuries include intracranial hemorrhage, spinal cord lesions, cephalhematoma, cranial or peripheral nerve palsies, intraabdominal organ rupture, or bony fractures. Risk for perinatal trauma and mortality is increased in primigravidas, multiple gestations, abnormal presentations, maternal-fetal disproportion, oligohydramnios, forceps or vacuum extractions, and internal version maneuvers. Very-low-birth-weight neonates (<1500 g) are at high risk due to ease of deformity of the cranium. Infants with certain congenital anomalies or pathologic processes that distort normal anatomy are also at increased risk, especially when a prenatal diagnosis is lacking. The authors present a case of a term gestation neonate who sustained a cervical spine dislocation fracture of C5-7, with subtotal transection of the spinal cord and resultant paralysis. The fetus was in vertex presentation, and a manual vaginal delivery was attempted. When the infant lodged in the birth canal following a difficult delivery of the head and arms, its enlarged abdomen was palpated, and the delivery was converted to an emergent cesarean section. The infant lived for 3 days and then expired due to neurologic complications of trauma sustained during the attempted vaginal delivery. Autopsy revealed a previously undiagnosed intraabdominal immature teratoma. The pathology of teratomas, the most common neonatal tumor and occasionally implicated in cases of birth trauma, will be addressed, followed by a review of the literature concerning birth trauma.     

Fatal splenic arterial aneurysmal rupture associated with chronic pancreatitis

Splenic arterial aneurysms (SAA) are rare and are usually atherosclerotic and/or related to pregnancy. Because pregnancy is the most important predisposing factor, the strong predilection of SAA for women is not surprising. The authors report a case of SAA rupture in a man with chronic pancreatitis as the predisposing factor. A 56-year-old man with abdominal pain and hematemesis was resuscitated and underwent endoscopy, but he died 18 hours later of massive hematemesis before definitive surgery could be carried out. At autopsy, there was chronic pancreatitis with fibrous adhesions tethering the tail of the pancreas, spleen, and posterior wall of the stomach together. The SAA was indented into the posterior wall of the stomach, into which it had ruptured from without. He also had alcoholic cirrhosis but no esophageal varices or conventional gastric ulcers. Other important predisposing factors such as abdominal trauma, infective endocarditis, polyarteritis nodosa, and segmental medial arteriopathy were absent. Histologic examination confirmed the rupture of the SAA. The SAA had Monckeberg medial calcinosis but little evidence of atherosclerosis. The well-documented complications of acute and chronic pancreatitis include shock, abscess, pseudocyst formation, and duodenal obstruction. This report describes the rare complication of SAA rupture, which may be fatal.     

Fatal intoxication with 1,4-butanediol: Case report and comprehensive review of the literature

A fatal case of 1,4-butanediol (1,4-BD) oral ingestion is reported here, in which a 51-year-old man was found dead in his bed. According to the police report, the deceased was a known drug user. A glass bottle labeled (and later confirmed to be) “Butandiol 1,4” (1,4-BD) was found in the kitchen. Furthermore, the deceased's friend stated that he consumed 1,4-BD on a regular basis. The autopsy and histological examination of postmortem parenchymatous organ specimens did not revealed a clear cause of death. Chemical-toxicological investigations revealed gammahydroxybutyrat (GHB) in body fluids and tissues in the following quantities: femoral blood 390 mg/L, heart blood 420 mg/L, cerebrospinal fluid 420 mg/L, vitreous humor 640 mg/L, urine 1600 mg/L, and head hair 26.7 ng/mg. In addition, 1,4-BD was qualitatively detected in the head hair, urine, stomach contents, and the bottle. No other substances, including alcohol, were detected at pharmacologically relevant concentrations. 1,4-BD is known as precursor substance that is converted in vivo into GHB. In the synoptic assessment of toxicological findings, the police investigations and having excluded other causes of death, a lethal GHB-intoxication following ingestion of 1,4-BD, can be assumed in this case. Fatal intoxications with 1,4-BD have seldom been reported due to a very rapid conversion to GHB and, among other things, non-specific symptoms after ingestion. This case report aims to give an overview to the published of fatal 1,4-BD-intoxications and to discuss the problems associated with detection of 1,4-BD in (postmortem) specimens.     

Suicidal ligature strangulation: case report and review of the literature

An unusual case of suicidal ligature strangulation is described. The victim is a 42-year-old white male who devised a very elaborate ligature mechanism comprised of thin wire, a plastic tub filled with water, and a combination of other common objects to commit suicide while in custody. A brief review of the literature follows.     

A case of Ludwig angina: a case report and review of the literature

Ludwig angina is a rapidly progressing submaxillary, submandibular, and sublingual necrotizing cellulitis of the floor of the mouth that can have lethal consequences due to airway obstruction. Various aerobic and anaerobic microorganisms, and less often fungi, have been implicated to cause Ludwig angina, including oral flora such as streptococci and staphylococci. Early recognition and the use of parenteral antibiotics can prevent mortality and morbidity. We report a case of a 25-year-old white man who was admitted to the hospital by his dentist after being diagnosed with Ludwig angina secondary to periodontal abscesses involving teeth #17 and #32. Although antibiotics were administered, while in the hospital, the decedent had difficulty swallowing and was drooling. He suddenly began to have seizure-like activity thought to be anoxic myoclonus. The decedent was aggressively resuscitated and taken to the operating room for neck exploration and a tracheostomy. Neck exploration revealed severe necrotizing acute inflammation of the deep soft tissues and musculature of the neck. He remained on life support for 7 days until he was declared brain dead. Ludwig angina is a progressive cellulitis that often results in death by asphyxia. Ludwig angina can be complicated by subsequent deep neck infection. The underlying etiologies and common scenarios are examined, and significant autopsy findings and dissecting procedures are discussed. The pathophysiology of Ludwig angina is studied with a review of the current literature.     

Massive systemic silicone embolism: a case report and review of literature

Subcutaneous injections of inert or quasi-inert plastic material designed to smooth out wrinkled skin or to create a more esthetically sought appearance have become very popular with the American public in general, and, in particular, with certain groups highly focused on their physical image. The case of the injection procedure has attracted into the field of plastic medicine a substantial number of illegal, incompetent, and unscrupulous operators. Their ignorance of involved medical risks and procedures not uncommonly results in severe complications, disfigurement, and death of patients. We report the typical pathological and chemical findings of a systemic fatal silicone embolism in a 53-year-old heterosexual woman following illegal chronic injections of silicone in her hips and buttocks. The injected subcutaneous silicone apparently migrated rapidly from the interstitial subcutaneous tissue into the general blood stream resulting in a fatal systemic silicone embolism. An analysis of the presented case in conjunction with a review of the pertinent medical literature, including a recent article, revealed a marked similarity in the clinicopathologic findings between silicone embolism and fat embolism.     

Verapamil toxicity: an unusual case report and review of the literature

Verapamil blocks the rapid influx of calcium into the cardiac myocytes of the cardiac conduction system and smooth muscle of the vasculature, resulting in decreased myocardial contractility, prolonged conduction time, and vascular relaxation. A sustained-release form, verapamil SR (or ER), is available that contains higher levels of medication and requires only once-daily dosing. The majority of reported fatal cases of verapamil toxicity are due to massive, intentional overdoses. Herein, we present an unusual case of fatal verapamil SR toxicity in a 57-year-old female that resulted from accidental overdose of only 3 tablets (720 mg), as witnessed by the decedent's daughter. In spite of the low dose ingested, the postmortem cardiac blood verapamil level was clearly toxic (6000 ng/mL, or 6 mg/L). Her preexisting medical conditions included hypercholesterolemia, hypertension, iron deficiency anemia, diabetes mellitus, and associated mild chronic renal failure. Complicating factors, which likely include the decedent's preexisting renal and cardiac disease, and a review of the available literature will be discussed.     

Traumatic rupture of the basilar artery: report of two cases and review of the literature

Two cases of traumatic rupture of the basilar artery are reported. In the first case, severe basal subarachnoid hemorrhage (SAH) due to a complete transverse tear of the basilar artery was observed in a 53-year-old restrained male driver who was involved in a head-on collision while intoxicated and drowsy. He lost consciousness shortly after the accident and was admitted to hospital in cardiopulmonary arrest. Intensive resuscitative therapies produced cardiac response, but he died 50 minutes after the accident. The ethanol concentration in his blood and urine was 0.35 and 0.55 mg/ml, respectively. In the second case, SAH due to a similar tear of the basilar artery was observed in a 47-year-old man who received several fist blows to the face while intoxicated. He suddenly lost consciousness after the final blow and was admitted to hospital in cardiopulmonary arrest. Intensive resuscitative therapies produced cardiac response, but he died 6 hours after the event. In these cases, the mechanism of the traumatic rupture of the basilar artery is thought to be overstretching due to hyperextension of the head, and intoxication, drowsiness, or both may have interfered with the decedents' ability to protect themselves; thus, the hyperextension of the head may have been rather forceful.     

Fatal virus-associated hemophagocytic syndrome in a young adult producing nontraumatic splenic rupture.

A 24-year-old man with no previous medical history was admitted to a local hospital with pancytopenia after a recent "viral illness." During his hospitalization, he developed sudden abdominal distension and hypotension. Surgical exploration of his abdomen revealed a ruptured spleen. The spleen was removed, but the patient did not survive the operation. We investigated this unexpected and unexplained hospital death for any traumatic or iatrogenic injury. The cause of death after review of the clinical history, autopsy, and microscopic sections was virus-associated hemophagocytic syndrome (VAHS). VAHS consists of a generalized histiocytic proliferation and marked hemophagocytosis associated with a systemic viral infection. Clinically it presents as pancytopenia and organomegaly. This recently described entity is often confused with malignant histiocytosis. This is the first case report of VAHS producing nontraumatic splenic rupture, thus adding to the differential diagnosis of spontaneous splenic rupture and sudden natural death.     

Sudden and unexpected death resulting from splenic artery aneurysm rupture: two case reports of pregnancy-related fatal rupture of splenic artery aneurysm

Rupture of a splenic artery aneurysm is a rare and usually catastrophic event, most commonly associated with pregnancy. In spite of increasingly common reliance on abdominal angiography, magnetic resonance imaging, and computerized tomography during the past quarter century, clinicians uncommonly recognize any of the various splanchnic arterial aneurysms absent premonitory signs or symptoms. Accordingly, rupture of a visceral aneurysm, including splenic artery aneurysm, typically presents as sudden, unexpected obtundation or death. As a consequence, the initial recognition and diagnosis of splenic artery aneurysm rupture take place only at autopsy. This report presents two such cases of sudden death resulting from splenic artery aneurysm in a pregnant woman and a postpartum woman, respectively.
