Prevention of tick bites and protection against tick-borne diseases in south-eastern Poland

The objective of this survey was to obtain information on the level of knowledge of prophylactic behaviour as a protection against fundamental tick-borne diseases among inhabitants of south-eastern Poland, and to determine whether the professions that increase the probability of tick contact, as well as previous contact with ticks, influenced the knowledge on tick-borne diseases and prophylactic behaviour of the respondents. The questionnaire included questions about gender of respondents, their place of residence and preventive behaviour against tick bite. The respondents were asked about the occupational hazard of working in tick infested areas, history of tick bites, awareness of diseases transmitted by ticks and the sources of their knowledge. The research was carried out in 2005. The most frequent preventive measures used were tick repellents (38 % ) and wearing protective clothing (35 % ). According to the questionnaire survey, 21 % of respondents did not take any preventive measures. The practice and form of prophylaxis was associated with the place of residence. In contrast to individuals from rural areas, a relatively low percentage of urban inhabitants used simple methods for protecting themselves against tick bites. Our survey indicates that the awareness of the Lublin region inhabitants concerning methods of tick bite prevention is still low and greater efforts are needed in promoting basic methods of protection and disseminating knowledge about these arthropods.

[Avantage double mobility press--fit cup in total hip arthroplasty]

The Avantage double mobility press-fit cup was devised by Dr. Bousquet in the 70's to bring reasonable response to a problem of recurrent dislocation after total hip arthroplasty. The cup is attached to the femoral head by a bipolar polyethylene liner. The polyethylene liner moves freely inside a shiny--polished metal cup. The angular range of motion before impingement is increased by the mobility of the liner. The double connection (cup-liner, liner-head) reduces the stress on the metal cup and improve the stability of the prosthesis. The solution has proved to be efficient in reducing dislocation risk and maintains at the same time the appropriate range of motion. Between January 2004 and November 2005, 113 hip arthroplasties in 108 women with use of the double mobility cup were performed. The cemented version of the Avantage cup was inserted in 15 patients (mean age--76.9 years). Uncemented, HA coated implant was used in 98 patients (with mean age of 55 years). The mean follow-up was 20.4 months. No one patient was lost to follow-up. No postoperative dislocation was observed during follow-up. There was no unwanted leg lengthening greater than 1 cm. The Avantage cup may be indicated in any primary total hip arthroplasty especially in those with increased risk of postoperative dislocations. This cup enables a correct balance of the hip without a need of the unwanted lengthening of the leg.

[Local anomalies in ticks larvae (Acari: Ixodida)]

Three anomalies in the anus structure of Hyalomma marginatum marginatum larvae, two anomalies in Argas reflexus larvae, i.e. the lack of the left chelicera and the second pair of limbs at the right side, and disorder in chetotaxy of Argas persicus larvae were examined in this research. These anomalies have not been described so far in the literature.
