Subcutaneous hydatid cyst in the popliteal fossa at the site of a previous wasp sting.

We report an uncommon case of a primary Echinococcus cyst that developed in the subcutaneous tissue of the right popliteal fossa, at the spot of a previous wasp sting, suggesting the possibility of an unusual transmission of the eggs by insects. This unusual presentation was initially considered as a Baker cyst until parasytological results verified Echinococcus hydatidosus, the larval form of Echinococcus granulosus, as diagnosis. However, the most common path of Echinococcus granulosus infection is through contact with a definitive host or by ingestion of ova through contaminated water or food. Transmission by insects should also be reconsidered in endemic areas.

The effect of an organized, nationwide breast cancer screening programme on non-organized mammography activities.

OBJECTIVES: To analyse the effect of an organized, nationwide breast cancer screening programme on non-organized mammography activities in Hungary. SETTING: The nationwide dataset of the Hungarian National Health Insurance Fund Administration covering the years 2000-2005. METHODS: Data derived from the nationwide database of the Hungarian National Health Insurance Fund Administration. The study includes all women undergoing mammography before (2000-2001) and after (2002-2003/2004-2005) the introduction of organized screening. RESULTS: The number of women having non-organized (opportunistic/diagnostic) mammograms was around 250,000 in 2000-2001, but increased to 350,000 in 2005. In the age group 45-64 years in 2000-2001, only 27.4% of all women undergoing mammography were examined within locally-organized programmes. After the introduction of the nationwide programme, this percentage increased to 61.0% in 2002-2003, and 56.3% in 2004-2005. After the introduction of the nationwide organized programme (2002-2003), the proportion of organized screening mammographies remained among the highest in county Hajdú-Bihar (78.4%) and Zala (88.3%) and increased significantly in county Vas (87.7%). CONCLUSION: The introduction of an organized nationwide screening programme in Hungary resulted in increases in the number of screening mammographies, and also of non-organized mammographies. Although the ratio of organized screening versus non-organized mammography changed in favour of screening mammographies, there are large within-country differences between counties.

[Investigation of the gene locus in autosomal polycystic kidney disease in a 21 year old female patient with congenital hepatic fibrosis and polycystic liver]. / Az autoszomális recesszív polycystás vesebetegségért felelós gén lokuszának vizsgálata egy congenitalis májfibrosisban és polycystás májbetegségben szenvedó 21 éves nóbetegnél.

BACKGROUND: Congenital hepatic fibrosis is an uncommon cause of portal hypertension in childhood or the early adolescence, usually presented with hepatomegaly and bleeding from esophageal varices. Despite the hepatomegaly and the fibrotic reconstruction of the liver the liver function tests are usually normal. In most cases it is associated with cystic disease of the kidneys. Congenital hepatic fibrosis is a constant feature of autosomal recessive polycystic kidney disease. CASE: The authors report on the case of a female patient with polycystic kidneys and polycystic liver. The symptoms of portal hypertension presented in the age of 20, on the basis of liver biopsy congenital hepatic fibrosis was diagnosed. AIMS: The authors intended to investigate whether there is genetic alteration as common etiology behind the rare association of congenital hepatic fibrosis confirmed in the adolescence and the polycystic disease of the liver and the kidneys. The clinical manifestation raised the possibility of autosomal recessive polycystic kidney disease. Segregation of microsatellite markers for autosomal recessive polycystic kidney disease gene locus 6p21.1-p12 was examined in the affected family to assess the possible role of theis gene. RESULTS: Four out of the 6 polymorphic microsatellite markers were informative, indicating that the autosomal recessive polycystic kidney disease may be responsible for the development of the rare association of the lesions of the liver and the kidneys in authors' patient.
