Abstract

The paper presents current distribution of Orobanche lutea Baumg. in Poland based on a critical revision of herbarium and literature data as well as results of field investigations conducted between 1999-2014. Majority of localities are centred around the Silesia-Cracow, Małopolska and Lublin-Lviv Uplands. The greatest density of sites with probably the most abundant populations in Europe is in the central part of Silesia-Cracow Upland, which, by several hundred years, was heavily exploited for calamine mining (rich in zinc, lead and silver). This resulted in the formation of large areas of gangue containing toxic heavy metals. Since limestone, dolomite, marl and postglacial calcareous clay and sands occur there in most places, the soil is often strongly calcareous. Populations of O. lutea contain here many thousands of shoots. The distribution of the species in Poland is mapped. The taxonomy, biology, ecology and threats are also discussed.

Abstract

Utricularia bremii Heer ex Kölliker has been found in a former sand quarry in Dąbrowa Górnicza (Silesia-Cracow Upland, S Poland). This subatlantic species is very rarely reported from Western and Southern Europe, and extremely rarely from Central Europe. Some localities were reported from Poland, mainly in the first half of the 20th century, but none of them are considered reliable and the species is not included in the flora of Poland. In the newly discovered locality the species forms a very abundant population in shallow, nutrient-poor ditches and pools. The origin of the population is uncertain, but before sand exploitation started the area was covered by extensive fens.

Videothoracoscopic Simultaneous Bilateral Posterior Splanchnicectomy - Initial Report

Chronic pain syndrome (CPS), accompanying pancreatic diseases, especially chronic pancreatitis and pancreatic cancer requires the strongest analgesic agents and is considered difficult to manage. Conservative methods are unsatisfactory and their side effects lead to serious somatic and mental comorbidities.

The aim of the study was to perform an initial evaluation of videothoracoscopic bilateral splanchnicectomy using the posterior approach, as the method of treatment in cases of advanced pancreatic cancer.

Material and methods. During the period between May and July 2005 there were 10 simultaneous bilateral videothoracoscopic splanchnicectomies (BVSPL) performed in patients with chronic pain syndrome, due to advanced pancreatic cancer, at the Department of General, Endocrinological and Transplant Surgery, Medical University of Gdańsk.

Results. All patients were discharged from the hospital on the second postoperative day. Subjective pain measured by the VAS scale changed from 84.3±7.6% before the operation to 25.3±5.3% during the first and second postoperative days. The median follow-up of patients was approximately 4 months (ranging between 2 and 6 months). The intensity of pain 2, 6, and 12 weeks after the procedure was 28.7±4.7%, 30.3±5.4% and 36.2±4.7%, respectively.

Conclusions. This is the first description of this safe and feasible method in the Polish surgical literature. The surgical procedure can be safely performed in most surgical departments equipped with videoscopic instruments. Moreover, the short learning curve enables surgeons to perform this procedure well after a short training period. In combination with good results concerning subjective pain reduction, it can be concluded that BVSPL should be incorporated into the spectrum of surgical procedures in most surgical departments in Poland.
