Evaluation of a transit first-aid station providing emergency care to former Yugoslavian war victims evacuated in Ancona, Italy.

BACKGROUND: A first-aid station was implemented in Falconara Marittima airport (Ancona, Italy). It provided medical emergency care to war victims evacuated from former Yugoslavia in transit for further treatment. MATERIALS AND METHODS: A descriptive analysis of the displaced population arriving at the first-aid station was performed using three independent datasets for administrative information, of which one included medical information. The implemented resources were also evaluated. RESULTS: From August 1993 to March 1995, 2272 displaced persons were registered at the first-aid station, out of which 54.2% were accompanying family members. Among those needing medical intervention (45.8% of total), most frequent diagnoses were traumatisms and burns (59.8%), neoplasms (15.6%), and congenital malformations (13.2%). The medical care provided at the first-aid station was most often basic: a medical examination alone was performed on 77.0% of the patients, and a minor dressing on 17.3%. Median length of stay was 1 day. Patients were sent to 30 different countries and 8% were forwarded to the local regional hospital. Deployed logistical resources exceeded by far actual needs but a lack of psychological assistance was observed, mainly for children. The agencies involved did not coordinate data sharing and follow-up information. CONCLUSIONS: The medical assistance to the war victims was efficient regarding provided care and timeliness. Effectiveness of such a programme could be improved by a better coordination between partners, allowing more adequate logistics according to appropriate epidemiological information.

Clinical evaluation of the effect of calcium-channel blockers on verbal learning.

The effect of verapamil and nimodipine on verbal learning was evaluated in a double-blind clinical trial. Thirty-seven healthy volunteers were distributed in three groups to receive a treatment with nimodipine, verapamil or placebo. Neither verapamil nor nimodipine modifies verbal learning as measured by the selective remembering test of Buschke and Fuld.

Diphtheria: epidemiological update and review of prevention and control strategies.

The importance of anti-diphtheria immunity in adults through periodic booster doses of vaccine is now increasing after last years diphtheria outbreaks in Newly Independent States (NIS) and Algeria and a few cases found in Europe and USA. Diphtheria cases notified in Italy between 1991-1994 have been reported. In 1995 WHO outlined the need to review vaccination schedules against diphtheria in all countries where gaps occur in the immunity of adults. The main sero-epidemiological studies performed in adults and vaccination schedules against diphtheria in some industrialized countries have been examined. Actual situation and control strategies adopted by WHO in the NIS and implications for other countries have been briefly presented. Finally, guidelines for management, investigation and control of diphtheria have been reported, including CDCs recommendations.

Syphilis and blood donors: comparison of two different diagnostic strategies.

In this study the validity of the methods provided for by Italian law (VDRL or RPR tests) were compared with the diagnostic strategy suggested by WHO (the use of VDRL and TPHA tests in parallel). Sensitivity, specificity and posterior probability of infection after a positive or a negative result were estimated. The application of two tests in parallel produces a statistically significant increase of sensitivity from 47% to 98% while the increase of proportion of false positives is not significant (from 15% to 16%). Probability of infection when the result is negative to the RPR is 0.07% while a negative result to the RPR and the TPHA tests has a probability to be really infected of 0.003%. The use of the two tests (RPR and TPHA) in parallel is able to give the highest degree of sensitivity, indispensable to select possible blood donors, while maintaining a good degree of specificity. The authors concluded that the use of VDRL alone does not exclude infectivity of a blood sample, and in accordance with WHO and international recommendations, the VDRL or RPR and TPHA tests should be used in parallel for syphilis screening.

The erythrocyte-granulocyte rosette. An immune cellular interaction found in some cases of autoimmune hemolytic anemias.

Erythrocyte-granulocyte rosettes (EGR) were found in the capillary blood of two cases of autoimmune haemolytic anemia, the first caused by an IgM non-I antibody and the second by an IgG. Both antibodies activated complement, and C3b was demonstrated on the erythrocytes. The rosettes appeared as arrangements of 6-10 red cells adhering to a central granulocyte; phagocytosis was most generally absent. The finding of EGR in the capillary blood may be useful for the recognition of complement activation up to the C3b stage in some cases of autoimmune haemolytic anemia.
