The analysis of cranial and facial fractures in skeletal remains of homicidal victims can prove challenging for forensic anthropologists and forensic pathologists in postmortem examination. In such cases, the use of 3-D computerized imaging to elucidate the fractures and patterns of injuries can provide strong medical evidence that is very useful during(More)
A unique case of a malignant oncocytoma of the maxillary sinus is reviewed in detail. The ultrastructural findings are presented. The histologic and ultrastructural criteria that characterize oncocytes and the clinicopathologic features of benign and malignant oncocytomas are discussed. This case represents the eleventh reported case that would truly(More)
This report describes certain interesting postmortem findings in the hearts of five subjects who died suddenly, silently, and unexpectedly, and in whom the only significant abnormality at autopsy was asymmetric septal hypertrophy (ASH) of the heart. Deep clefts, cystic faults, and dilated vascular channels were not only seen within the septal myocardium in(More)
A large invasive pituitary neoplasm, surgically resected by left frontotemporal craniotomy, and thought to represent "chromophobe" adenoma by light microscopy, exhibited ultrastructural features characteristic of oncocytoma. Electron microscopic and immunocytochemical studies showed that the tumor did not possess enhanced secretory activity. The(More)
Ninhydrin reacts with various nitrogen-containing compounds, including some that are released from a body during decomposition. Previous research has shown that ninhydrin can be used to identify gravesoils, however, its potential value in death scene reconstruction has not been previously demonstrated. To explore this possibility, the concentration of(More)
Deliberate ingestion of a corrosive acid is an unusual manner of death. Sulfuric acid, often used in electrical industry, chemical laboratories, and agriculture, is fatal at a dosage of 3.5-7.0 ml. The mortality rate is quite high, with only 35% recovery rate. Poisoning by sulfuric acid resembles other mineral acids in that the esophagus is more commonly(More)
We report what we believe to be the first proven marked concomittant elevations in serum creatine kinase (CK) and lactic dehydrogenase (LD) in a patient with bowel necrosis. The necrosis was the result of infarction secondary to bowel strangulation. The serum from this patient showed elevation of total CK activity resulting from an abnormal amount of MM,(More)
