Antifreeze (ethylene glycol) intoxications in Baltimore. Report of six cases.

Records of the Office of the Chief Medical Examiner (OCME) for the State of Maryland were reviewed for all deaths related to acute ingestion of antifreeze (ethylene glycol [EG]) occurring between December 1985 and December 1987. Six cases were identified. In three cases, the manner of death was classified as undetermined, in two suicide, and in one case the intoxication was considered to have contributed to death, but was not the main cause. Clinically, the hospitalized subjects exhibited primary metabolic acidosis with hypocalcemia, hyperglycemia, and an elevated anion and osmolar gap. At autopsy, the findings related to EG ingestion were typical of a non-specific drug intoxication. Histological examinations in five cases demonstrated the presence of calcium oxalate crystals in the renal tubules; in three cases extensive renal tubular necrosis appeared related to the survival time. The toxicological analysis in three cases revealed lethal EG levels in the blood.

The "mini-packer" syndrome. Fatal ingestion of drug containers in Baltimore, Maryland.

We report seven fatalities resulting from the ingestion of illicit drugs packaged in condoms, rubber balloons, or plastic bags which were observed in the last 4 years at the Office of the Chief Medical Examiner, State of Maryland. All the victims, with the exception of one, were men ranging in age from 19 to 37 years. There was no racial predominance. No drug paraphernalia was found at any scene. In two cases, seizure-like activity was documented. One victim had recently returned from Nigeria; therefore, Lassa fever was initially suspected. Two of the victims were "body packer" contrabanders who had just arrived from Africa. They used body cavities to hide large amounts of heroin to avoid U.S. Customs. The other five cases were "mini-packers," small-time illicit drug dealers who had swallowed a single bag of cocaine to avoid police detection. The possible mechanism of leaking or rupture of the latex container is discussed.

Computer-aided skull/face superimposition.

By use of a special optical device coupled with a TV camera to match a skull and a photograph of a face, superimposition for the purpose of personal identification was performed in controlled situations. A computer-aided method to evaluate the fit of the superimposition has been outlined by means of an original Shape Analytical Morphometry (SAM) software package yielding analytical descriptions by kth-order poly-nominal equations and Fourier harmonic analysis. The match was carried out by using point-cross error and sum of differences for the Fourier set amplitude. A final comprehensive evaluation exhibited marked differences between congruent and noncongruent superimpositions.

[Changes in the transparency of dentin: computerized densitometric analysis].

Computerized densitometry was utilized to carry out a quantitative and distributive study of dentin transparency in dental roots from different age individuals. By means of original software S.A.M. (Shape Analytical Morphometry) a densitometric reading of transilluminated whole dental root was performed and so obtained densitometric matrixes were worked for grey level classification and correspondent areas evaluation, false colour restitution, pseudotridimensional and row/column barr graphs, isodensity outlines and density inclination maps. Results are discussed for both age evaluation in forensic application and for altered dentin recognition in pathological conditions.
