RESUMEN
General paralysis is a neurological symptom of tertiary syphilis that was first identified in asylums as paralytic madness. The enlightened discussion of 60 clinicopathological cases provided by Louis Florentin Calmeil in his 1826 treatise greatly improved our knowledge of general paralysis. However, Calmeil was unable to relate this symptom to syphilis, although the latter was quite widespread at that time. Following a detailed reanalysis of Calmeil's observations with special attention to his clinical and demographic data, we conclude that this eminent clinician was unable to define the cause of general paralysis because his early 19th century mind was still under the influence of traditional knowledge and moral prejudices. For Calmeil, general paralysis belonged entirely to the realm of psychiatry.

The duplication of the acromioclavicular joint is a very rare anomaly of shoulder girdle. Here, we present a new case of unilateral duplication of the acromioclavicular joint observed on an individual from the 19th century. In the literature, two hypotheses are proposed to explain the origin of this anomaly. The first is a congenital origin that could be explained by in utero displacement of one of the clavicle's primary ossification centers, or the existence of an additional ossification center. The second is a traumatic origin resulting from an acromioclavicular fracture that occurred during the growth period of the individual. Our macroscopic observations and CT-scan images show no sign of a healed fracture, of complications, or of a bone callus after healing. The hypothesis of a congenital origin for this acromioclavicular duplication is therefore preferred.

This study shows that epithelial attachment level, used as age determination criterion in Lamendin's method, is not reliable for adults of either sex above the age of 49 years with periodontal diseases in any quadrant. The underestimation of calculated age increases from 7 to 19 years with chronological age. On the other hand, the present paper confirms the pertinence of dentin translucency as an age indicator in Lamendin's method.

This paleomicrobiologic study was conducted on osseous tissue specimens from ancient Hungarian skeletal samples from the 7-8th and the 17th centuries AD with typical macromorphologic evidence of osseous tuberculosis (n = 3), morphologic alterations probably due to tuberculosis (n = 6), or with nontypical osseous changes of vertebral bodies suggestive of inflammatory reaction (n = 5). From these bone samples, DNA was extracted and amplified by polymerase chain reaction (PCR) by using various primer pairs recognizing DNA segments of different mycobacterial species. To confirm specificity of the analysis, the amplification products of several samples were subjected to restriction enzyme digestion and/or direct sequencing. Of the analyzed 14 cases, 8 were unambiguously positive for mycobacterial DNA of the Mycobacterium tuberculosis complex, as shown by the amplification of the IS6110 sequence. In 13 cases we found a PCR product with primers specific for the 65-kDa antigen gene, including 2 cases without genomic DNA. We conclude that the application of other mycobacterial DNA primers may reveal contamination of bones with atypical saprophytic mycobacteria. A positive result for typical mycobacteria was seen in 2 of 3 cases with typical morphologic signs of tuberculosis and amplifiable DNA, in 3 of 6 probable cases, but also in 3 of 6 cases with nontypical bone changes. This indicates that minor osseous reactions of the surface of vertebral bodies may be due-at least in several cases-to infections with bacteria of the M. tuberculosis complex. In these cases the disease may have proceeded rapidly, and the morphologic osseous changes may represent "early" stages of tuberculous infection of the vertebrae.
