Indicators of genetic damage in alcoholics: reversibility after alcohol abstinence.

BACKGROUND/AIMS: Although a primary carcinogenic role of alcohol is not proven, alcohol abuse is associated with an increased risk of cancer of the upper airways, esophagus and liver. METHODOLOGY: Chromosome aberrations and the presence of micronuclei that reflect two types of genetic damage were analyzed in peripheral blood lymphocytes from 11 alcoholic patients who were heavy smokers and in a fair state of general nutrition and 9 subjects who had abstained from alcohol for at least a year. Ten heavy smokers were studied as healthy controls. RESULTS: Chromosome aberrations and micronuclei in alcoholics showed significantly elevated frequencies compared to the control groups, while in alcohol abstainers the values of all two parameters were similar to the values of the control subjects. CONCLUSIONS: These results show that long-term alcohol intake could induce genetic alterations in synergy with tobacco smoke. Interestingly, this damaging action is reversed by abstinence. Our results call for a further effort to find an eventual diagnostic role for these early genetic damage markers.

Different efficacy of alcohol education tools among trainee nurses.

BACKGROUND/AIMS: The evaluation of the efficacy of two different forms of scientific information concerning alcohol-related problems (ARP), among Italian trainee nurses. METHODOLOGY: A specific questionnaire, investigating the awareness of ARP, was distributed to 193 trainee nurses, 158 enrolled in the Italian Red Cross School for Professional Nurses at S. Orsola-Malpighi Hospital in Bologna and 35 enrolled in the Professional Nursing School at the Social Security Institute in the Republic of San Marino, who had attended a scientific meeting on ARP in the last year. Eighty-one nurses (62 belonging to the Red Cross School of Bologna and 19 to the Professional Nursing School of San Marino), had previously been given an information package on ARP (Group A). One hundred twelve subjects (96 belonging to the Red Cross School of Bologna and 16 to the Professional Nursing School of San Marino) did not read the specialized material (Group B). RESULTS: The results showed a statistically significant difference in the percentage of correct answers between Group A (25.98%) and Group B (21.80%). The percentage of correct answers among the Bologna trainee nurses were always significantly lower than that of the San Marino nurses. CONCLUSIONS: These results suggest a scant awareness and interest in ARP among trainee nurses and show that courses and lectures are more effective than scientific printed material.

[Detection of a focus of microfilariasis in northeastern Argentina].

A focus of microfilariasis was detected in El Oculto, Orán Department, 300 km northern from Salta city. These results prove the prevalence of this parasitosis in Argentina, despite the lack of cases registered during the last 35 years. The incidence detected was 20.7%; similar values were reported in 1917 by Biglieri and Aráoz in a wooded area located in the oriental face of Aconquija mountain, in Tucuman province, approximately 600 km southern from El Oculto. The results presented suggest the interruption in the transmission of this parasitosis.

Alpha-1-thymosin and transcatheter arterial chemoembolization in hepatocellular carcinoma patients: a preliminary experience.

BACKGROUND/AIMS: To evaluate the tolerability and therapeutic potential of the immunostimulating adjuvant alpha-1-thymosin in patients with hepatocellular carcinoma. METHODOLOGY: Twelve patients with hepatocellular carcinoma were treated with alpha-1-thymosin (900 micrograms/m2 subcutaneously twice per week for 6 months) and transcatheter arterial chemoembolization and compared to a historical control group (matched for gender, age, Okuda staging, Child's score, alpha-fetoprotein serum levels and viral infection) treated with transcatheter arterial chemoembolization alone. RESULTS: No severe side effects were recorded in the 2 treatment groups. The combination of alpha-1-thymosin plus transcatheter arterial chemoembolization resulted in a longer survival that reached statistical significance 7 months after the end of treatment (p < 0.05). Patients receiving combined treatment demonstrated a significant increase in peripheral blood mononuclear cells expressing CD3 (p < 0.05) and CD8 (p < 0.025) 3 months after beginning treatment. They also had a significant increase (p < 0.05) in CD16+ and CD56+ cells after 1 month, and a slight reduction in mononuclear cells expressing CD25, a marker for cell activation. No alterations in the response to phytohemagglutinin stimulation were seen during the alpha-1-thymosin treatment. CONCLUSIONS: The absence of toxicity and the favourable effects observed in this open study call for a double blind control study to confirm the efficacy of the combined treatment.
