[Pertussis in 1997].

In 1997 an epidemic increase of pertussis was observed in Poland. The incidence was 5.4/100,000 population and was more than six times higher than in the preceding year. No clear reason for a sudden increase in pertussis incidence was found, in particular the vaccination coverage rates have remained high. In December 1997 the DTP vaccine coverage rate for children below two with four doses of DTP was 97.5%. The distribution of cases according to age during the last 20 years was analysed and it was shown that since the beginning of the '90 a growing proportion of cases occurs among fully vaccinated children and the average age of the cases has a steadily growing tendency. A hypothesis was put forward that the come-back of pertussis is presently due to waning of short-term immunity following immunisation, in cohorts of children who grew up in conditions of very low B. pertussis natural transmission. An open question remains whether to introduce to the immunisation calendar an additional booster dose of pertussis vaccine in school-aged children.

[Tetanus in 1997].

In 1997, 37 cases of tetanus were registered in Poland. The incidence rate of tetanus was 0.1/100,000 population. No neonatal tetanus cases were recorded. The last neonatal tetanus case had been reported in this country 14 years ago and the last death from neonatal tetanus over 30 years ago. Two tetanus cases occurred in persons aged 20 and 28, who underwent a full course of tetanus vaccination and received their last booster dose of tetanus vaccine not more than 10 years ago. 70% of cases occurred in persons aged 60 and over. Case-fatality rate associated with tetanus was 27%. By the end of 1997, 97.8% of children born in 1996 have been immunized with at least three doses of DTP vaccine. High vaccine coverage rates in Poland maintained since many years are an effective means of eliminating tetanus in the population. Since many years a decreasing number of tetanus cases are registered.

Knowledge of seamen and fishermen on risk factors of diseases of the circulatory system.

A total of 1352 seafarers and deep-sea fishermen were interviewed with the use of a questionnaire regarding their knowledge on risk factors in cardiovascular diseases. A great majority of them knew about the harmful effect of tobacco smoking (88.4 per cent of persons interviewed), arterial hypertension (75.7 per cent), and diet rich in fats which contributes to increasing the level of serum cholesterol (75.2 per cent); only 43.2 per cent marked diabetes mellitus as a risk factor. The knowledge on the above risk factors was not enough to change their attitude and habits, with regard to smoking and diet. Preventive interventions should be intensified on ships in order to promote the health of crews. Maritime medicine staff should play more active role in this health promotion programme.

[Arrhythmias in healthy sailors].

Results are presented of 24-hour monitoring by Holter's method of ECG in 50 healthy seamen aged 29-55 years (mean 47.7 years), in whom clinical examination, chest radiography, resting ECG records, and echocardiography confirmed normal condition of the cardiovascular system. In 36% of the seamen premature beats of various origin were elicited. Supraventricular extrasystolic beats were demonstrated in 8%, atrioventricular-junction beats in 8%, and ventricular ectopic beats in 18%. In one case simultaneous occurrence of junction beats and ventricular beats was found. In 28% of the subjects sinus bradycardia was noted, and in 1 seaman two episodes of sinus tachycardia were recorded. The intensity of the observed arrhythmias was low.
