Background: Radiofrequency thermal ablation has been used as a treatment for several types of hepatic malignancies. Many of these lesions exist in the presence of cirrhosis. Limitations exist to the size of the ablations and, subsequently, the efficacy of treatment. Hepatic vascular inflow occlusion has been advocated as an adjunctive measure to increase(More)
OBJECTIVE We performed a study to determine the correlation between the diameter of the echogenic response observed with intraoperative sonography during radiofrequency ablation of the cirrhotic liver and the mean diameter of tissue necrosis. SUBJECTS AND METHODS A total of 22 intraoperative radiofrequency ablations were created in 11 cirrhotic livers.(More)
A 19-year-old G1P0 Caucasian woman died 8 days postpartum because of the subinvolution of the uteroplacental arteries. Microscopic examination of the placental implantation site revealed large, dilated spiral arteries containing partially occluding thrombi in the superficial myometrium. The presence of cytotrophoblasts within and surrounding the spiral(More)
A retrospective review of 1704 cases of suicide involving firearms investigated by the Bexar County Medical Examiner's office between 1984 and 1998 was performed. The age distribution was similar in male and female victims, and the type of weapon was not associated with age. Approximately 78% of the victims used a handgun (87% of female and 76% of male(More)
The red (Solenopsis invicta) and black (Solenopsis richteri) imported fire ants (IFA) are a common cause of venom allergy in the southeastern United States. Hypersensitivity to stings of native fire ants is less common, although anaphylaxis has been reported to various native Solenopsis species. There have been numerous reports of indoor stings caused by(More)
The authors report the case of a 47-year-old black man with a history of multiple sclerosis who was found dead in a bathtub, head above water, with a body temperature of 105.7 F. Results of a complete autopsy and toxicologic screen were negative. Individuals with multiple sclerosis, if immersed in hot water, develop motor weakness, which may be so severe as(More)
BACKGROUND Venous thrombosis followed by pulmonary embolism is one of the most common causes of sudden death among middle-aged adults. Several inherited polymorphisms are associated with heightened risk of venous thrombosis, including mutation at position 20210 of the prothrombin gene and mutation at codon 506 of the factor V gene. METHODS We studied(More)
Microscopic examination was performed on 55 cases of traumatic liver lacerations incurred from fatal motor vehicle accidents. None of the deaths was due to the liver injury. In 38 of 55 cases, the decedent was pronounced dead at the scene. Microscopic examination of the liver lacerations in these 38 cases revealed no histologic changes related to the(More)
