"The moon" and "the blood": two emblematic symbols in headache and epilepsy according to scientific traditions of the Salerno Medical school and popular medicine in southern Italy.

Before describing the state of knowledge on headache and epilepsy at the Salerno Medical School (SMS), we will briefly summarize in the first part its history through the centuries until the "golden period" of the 12th century when it reached its peak by outshining all others in teaching, studies and research. In the second part we will refer to Saint Donato, healer of epileptics in the south of Italy, whose worship is still alive today. The finding of common symbols in conceptions of headache and epilepsy, both in the scientific tradition of the School and in popular medicine, represents a link which is explicable by the wide dissemination of the school's doctrines.

Selenium, the element of the moon, in life on earth.

The present status of selenium biochemistry is reviewed with particular emphasis on biomedical problems related to the selenium status of humans and experimental animals. Historical milestones of selenium biochemistry starting from the identification of the first selenoenzymes up to the elucidation of prokaryotic and eukaryotic selenoprotein biosynthesis are compiled. Topical hypotheses on the biological role of selenium in general and of individual selenoproteins in respect to antioxidant defense, redox regulation of metabolic processes, thyroid function, spermatogenesis, oncogenesis, and atherogenesis are critically evaluated.

UV photochemistry of DNA in vitro and in Bacillus subtilis spores at earth-ambient and low atmospheric pressure: implications for spore survival on other planets or moons in the solar system.

Two major parameters influencing the survival of Bacillus subtilis spores in space and on bodies within the Solar System are UV radiation and vacuum, both of which induce inactivating damage to DNA. To date, however, spore survival and DNA photochemistry have been explored only at the extremes of Earth-normal atmospheric pressure (101.3 kPa) and at simulated space vacuum (10(-3)-10(-6) Pa). In this study, wild-type spores, mutant spores lacking alpha/beta-type small, acid-soluble spore proteins (SASP), naked DNA, and complexes between SASP SspC and DNA were exposed simultaneously to UV (254 nm) at intermediate pressure (1-2 Pa), and the UV photoproducts cis,syn-thymine-thymine cyclobutane dimer (c,sTT), trans,syn-thymine-thymine cyclobutane dimer (t,sTT), and "spore photoproduct" (SP) were quantified. At 101.3 kPa, UV-treated wild-type spores accumulated only SP, but spores treated with UV radiation at 1-2 Pa exhibited a spectrum of DNA damage similar to that of spores treated at 10(-6) Pa, with accumulation of SP, c,sTT, and t,sTT. The presence or absence of alpha/beta-type SASP in spores was partly responsible for the shift observed between levels of SP and c,sTT, but not t,sTT. The changes observed in spore DNA photochemistry at 1-2 Pa in vivo were not reproduced by irradiation of naked DNA or SspC:DNA complexes in vitro, suggesting that factors other than SASP are involved in spore DNA photochemistry at low pressure.

Acute myelogenous leukemia in elderly patients not eligible for intensive chemotherapy: the dark side of the moon.

BACKGROUND: Acute Myelogenous Leukemia (AML) is a common disease in people aged>60 years. About 50% of the patients are not eligible for aggressive chemotherapy (CT) and are only managed with conservative approaches. Results in this subset of patients have not been reported so far. PATIENTS AND METHODS: We retrospectively evaluated 244 consecutive elderly AML patients (M/F 143/101, median age 72 years, range 60-90) diagnosed at our institution from January 1989 to December 1998 and not eligible for intensive CT. Eighty-nine patients (36.5%) had evolved from previous myelodysplasia (sAML). Fifty-three out of 192 (26.4%) patients with available bone marrow (BM) analysis had oligoblastic leukaemia (blasts<40% and WBC<15x10(9)/l). RESULTS: Sixty-seven patients (27.5%) were managed with supportive treatment only. One hundred seventy-seven patients (72.5%), in order to control disease, received conservative CT, consisting of Hydroxyurea (HU) (127 patients, 71.7%), Cytarabine and 6-Thioguanine (39 patients, 22%) or low-dose cytarabine (11 patients, 6.3%). Median overall survival was 179 days (1-3278) with 50 patients (20.5%) surviving>12 months. Older age (>75 years), poor WHO PS (>2), lower PLT levels (<50x10(9)/l) and higher absolute peripheral blast count (>5x10(9)/l) showed a negative prognostic impact on survival in multivariate analysis. CONCLUSIONS: Our data outline the great heterogeneity of elderly AML patients not eligible for intensive CT. A simple scoring system including easily evaluable parameters, which could distinguish subjects with different prognosis, is proposed. Moreover, randomized studies in order to establish best conservative approaches are warranted.

Scopolamine poisoning from homemade 'moon flower' wine.

LH, a 76-year-old Caucasian male, ingested 3 teaspoons (15 mL) of a homemade wine over a 1-h period and became ill. Approximately 1.5 h later, he was taken to the emergency room of a local hospital with symptoms of respiratory distress and weakness. The plant used in making the wine was Angel's trumpet (Datura suaveolens), which reportedly contains varying amounts of scopolamine and atropine. A sample of the wine was collected and analyzed for these two compounds by reversed-phase HPLC chromatography using 97% methanol-3% deionized water. The filtered wine contained an estimated 29 mg scopolamine/mL, which produced a total ingested dose of 435 mg. No atropine was detected. The scopolamine was confirmed by TLC. An oral dose of 50 mg of atropine sulfate in humans has been reported fatal, but there is no reported fatal dose for scopolamine. The alcohol content and 3.8 pH of the homemade wine may have increased the extraction of this compound from the plant material, and the wine fermentation process may have concentrated the original extract.
