The paleopathological study of 40 Italian Renaissance mummies has allowed us to perform about 20 diagnoses, of which 5 concern infectious (smallpox, hepatitis, condyloma, syphilis and pneumonia), 4 metabolic (obesity, atherosclerosis, gallstones and uric acid nephrolithiasis), 2 articular (DISH and rheumatoid arthritis) and 2 neoplastic (skin apithelioma and colon adenocarcinoma) diseases. The mummy of an anonymous child, dated back to the 16th century (C14=1569 +/- 60), presented a diffuse vesiculo-pustular exanthema. Macroscopic aspects and regional distribution suggested smallpox, while EM reavealed many egg-shaped, virus-like particles (250 x 50 nm), with a central dense core. Following incubation with anti-smallpox virus antiserum and protein A-gold complex immunostaining, the particles resulted completely covered with protein A-gold. These results clearly show that this Neapolitan child died of a severe form of smallpox some four centuries ago. The mummy of Maria of Aragon, Marquise of Vasto (1503-1568), reavealed on the left arm an oval, cutaneous ulcer (15x10 nm) with linen dressing. Indirect immunofluorescence with anti-treponema pallidum antibody identified a large number of filaments with the morphological characteristics of fluorescent treponemes. EM evidenced typical spirochetes, with axial fibril. These findings clearly demonstrate a treponemal, probably venereal, infection. The mummy of Ferrante I of Aragon, King of Naples (1431-1494), revealed an adenocarcinoma extensively infiltrating the muscles of the small pelvis. A molecular study of the neoplastic tissue evidenced a typical mutation of the K-ras gene codon 12:the normal sequence GGT (glycine) was altered into GAT (aspartic acid). At present this genetic change is the most frequent mutation of the K-ras gene in sporadic colorectal cancer. The alimentary "environment" of the Neapolitan court of the XV century, with its abundance of natural alimentary alkylating agents, well explains this acquired mutation. These and other diseases as, for example, a fatal puerperal complication, a thyroid goiter, a case of Wilson's cirrhosis, some cases of anthracosis and other peculiar traumatic conditions, such as a mortal stab-wound, can elucidate the pathocenosis of the wealthy classes of the Italian Renaissance.

This is a case report of a reservist who presented for a physical examination with hypertension. It was discovered that the reservist was unknowingly taking large doses of Ephedra sinica, or ma huang, a Chinese herbal supplement, for body-building. One of the ingredients in ma huang is ephedrine, an active alpha- and beta-adrenergic stimulant that produces increases in heart rate, blood pressure, and cardiac output. Ma huang has been reported to cause hypertension, hepatitis, nephrolithiasis, and sudden death in healthy, normotensive people. Ma huang will produce a positive urinary drug screen for stimulants and can be a drug of abuse. A recommendation is made to screen for dangerous supplement use before physical readiness training and to stop the supplement for 1 month before beginning any exercise program.

The mean risk of acquiring HIV after an occupational exposure, injecting drug use or sexual exposure varies from < 0.1 to 3%. A high plasma HIV-RNA of the source increases the risk of each of the exposures. Other factors, such as the volume of the inoculum involved to which the individual was exposed, other sexually transmitted diseases and ruptures of mucous membranes are associated with a higher risk of HIV transmission. Based on the calculated risk, post-exposure prophylaxis (PEP) should be recommended. In the Netherlands, prescription of PEP in the occupational setting is a standard procedure and has proved to be feasible. This was associated with a high percentage (62%) of mild and reversible toxicity and a small percentage (2%) of serious adverse events related to antiretroviral drugs, i.e. nephrolithiasis (due to indinavir) and toxic hepatitis (due to nevirapine). In The Netherlands so far no HIV-seroconversions have been recorded after an occupational accident.
