A case of attempted suicide by ingestion of 4.8 g As2O3 (more than 20 times the estimated lethal dose) is reported. Absorption of arsenic caused elevated urinary levels over 5 days BAL treatment was started within three hours after arsenic ingestion. The patient did not develop any signs of polyneuropathy or other clinical changes.

A 41-year-old vintner attempting suicide ingested 8-9 g of arsenic and developed a symmetric polyneuropathy with acute Wallerian degeneration of myelinated fibers. Under treatment with modified British Anti-Lewisite (BAL; "Dimaval") his polyneuropathy slowly, but incompletely, subsided over three years at which time another sural nerve biopsy specimen showed regenerative proliferation of myelinated and unmyelinated axons but no signs of Wallerian degeneration. By laser microprobe mass analysis (LAMMA) arsenic was located in the first biopsied sural nerve specimen but not in the second specimen. These findings demonstrated: 1) arsenic induced serial morphometric and electron microscopic findings of nerve fiber degeneration and regeneration, 2) documentation of arsenic within myelinated nerve fibers, and 3) the usefulness of the LAMMA technique as a diagnostic procedure in this context.

A 31 year-old inhabitant of French Guiana was prescribed mercuric iodide per os for two and a half months. Shortly before the end of the treatment he developed fasciculations in the trunk and particularly the lower limb muscles, distal painful paresthesias with vasomotor disorders, episodes of excessive perspiration and palmoplantar erythema, moderate fluctuating hypertension, progressive loss of weight and irritability with insomnia. Clinical and electrical signs of neuropathy were lacking. The clinical picture was that of Morvan's fibrillary chorea with acrodynia, the conditions of onset strongly suggesting a mercurial intoxication. Blood and particularly urine mercury levels were elevated. Administration of dimercaprol (BAL) considerably increased urinary excretion of mercury and there was progressive improvement and finally recovery after two months of BAL treatment. This case exemplifies the possible co-existence of fibrillary chorea and acrodynia. Whereas in many cases of fibrillary chorea a precise etiology cannot be determined, the affection can be induced by mercury as by gold administration. The fact that cases of fibrillary chorea due to mercury poisoning are rarely reported may be the result of individual patient hypersensitivity or particular metabolic absorption and excretion features of mercury. This case cannot be included within the continuous activity syndrome of muscle fibers described by Isaacs, since muscle contractures were absent and there was associated acrodynia. Moreover, there was no latent polyneuropathy, in spite of the intense fasciculations. It must be concluded, therefore, that in spite of its rarity fibrillary chorea should keep its semiologic autonomy.

A case of a 27-year-old woman who ingested 9000 mg arsenic trioxide (As2O3) is reported. Classical symptoms of an acute arsenicum (As) poisoning such as gastrointestinal cramps, vomiting, diarrhea, ECG changes and disturbed liver function tests were observed. The absorption of the ingested As was minimalized by a continuous gastric irrigation with highly concentrated NaHCO3 and intestinal cleansing with NaHCO3 and polyethyleneglycol was performed. Forced diuresis, BAL (2,3-dimercaptopropanol) and DMSA (meso-2,3-dimercaptosuccinic acid) were started and therapy to enhance the formation of methylated As derivatives, which are potentially less toxic and which can be excreted more easily, was then administered. The patient survived this massive dose of ingested inorganic As with only polyneuropathy one year later.

The association of human herpesvirus-7 with lung diseases is poorly known, although it has been suggested a role in causing interstitial pneumonia in non-transplant patients and bronchiolitis-obliterans-organizing-pneumonia in lung transplant. No case of acute respiratory distress syndrome associated to human herpesvirus-7 has been reported, while only one case associated with human herpesvirus-6 has been described in an immunocompetent patient. This report describes the identification of human herpesvirus-7 reactivation in an immunocompetent patient with acute respiratory distress syndrome, as evidenced by the increasing viral load in bronchoalveolar lavage, polyneuropathy, histopathological findings, and tissue positivity. Human herpesvirus-7 reactivation in this context could be a consequence of the tissue damage due to the underlying lung disease, rather than the cause, as suggested by the temporal profile of viral load on BAL.
