The study presented a case of a 29 year-old male patient with a pseudoaneurysm of the splenic artery as a complication of acute pancreatitis. The pseudoaneurysm was incidentally diagnosed during control angio-CT. The patient underwent immediate surgery due to deterioration of his clinical condition. During laparotomy the pseudoaneurysm, spleen and part of the pancreatic tail were excised. The postoperative course proved uneventful and the patient was discharged from the hospital after seven days.

Abstract

The Służew Stream, a 14.9 km long watercourse, is part of an ancient river called Sadurka that starts its course in the Warsaw district of Ochota and flows into the Wilanów Lake. In the 19th and 20th centuries, the watercourse received industrial and municipal sewage from Warsaw and its environs, but nowadays only rain and snow meltwater is discharged into the stream. Freshwater sediments of five reservoirs in the catchment area of the Służew Stream - Wilanów Lake, Powsinów Lake, Pond in the Horse Racing area, Lake at Morgi and South Pond in the Wilanów Park - were analysed for the contents of Cr, Cu, Pb, Zn, Ni, Cd and Hg. The following concentrations have been determined: chromium - from 5 to 274 mg/kg, copper - from 5 to 274 mg/kg, lead - from 3 to 310 mg/kg, zinc - from 44 to 1430 mg/kg, nickel - from 3 to 55 mg/kg, cadmium - from 0.3 to 37.3 mg/kg and mercury - from 0.010 to 0.810 mg/kg (Fig. 2-5). The studies have shown that water sediments of Pond in the Horse Racing area, South Pond and Wilanów Lake, supplied by the Służew Stream waters, are characterised by a very high content of heavy metals. In contrast, water sediments of Powsinów Lake and Lake at Morgi, recharged by drainage ditches flowing into the stream, are characterised by much lower concentrations of these elements, but the levels are still much greater than the geochemical background.

Abstract

Laparoscopic surgery has become a well approved method of abdominal hernias treatment in recent years. Due to the advancement of laparoscopy and the use of improved synthetic materials laparoscopic surgery is characterized not only by low complication but also by a short period of recovery after surgery.

The aim of the study was a retrospective analysis of the results of laparoscopic abdominal hernia surgeries (IPOM).

Material and methods. Between year 2007 and 2012, 65 patients aged between 29 to 76 underwent laproscopic abdominal hernia surgeries due to either primary or postoperative abdominal hernias. All patients were examined in perioperative period, after 12 and 24 months after surgery in search of complications, pain and reccurence. Recovery period was also estimated.

Results. In most cases postoperative pain was estimated from 1 to 4 on VAS scale. The most frequent complications were seromas that occured in 3 patients. The other complications were pneumothorax, wound hematoma and wound infection that occured once each. One patient required reoperation due to wound hematoma. Chronic postoperative pain was diagnosed in 3 patients and 4 recurrences were stated.

Conclusions. Laparoscopic therapy of abdominal hernias is a safe operative method characterized by low recurrence and complication rates as well as short hospital stay and quick recovery. This technique is restricted by high material costs and the lack of full refund for the procedure.

Abstract

The aim of the study was to evaluate the usefulness of indirect methods of assessment of VO2max for estimation of physical capacity of trained male and female rowers during a training cycle. A group of 8 female and 14 male rowers performed the maximal intensity test simulating the regatta distance (a 2 km test) and a submaximal incremental exercise test on a rowing ergometer. The suitability of the indirect methods of predicting VO2max during the training cycle was evaluated by performing the tests twice: in females at an interval of five months and in males at an interval of seven months. To indirectly estimate VO2max, regression formulas obtained for the linear relationship between the examined effort indices were utilized based on 1) mean power obtained in the 2 km test, and 2) submaximal exercises after the estimation of PWC170. Although the suitability of the two indirect methods of assessment of VO2max was statisticaly confirmed, their usefulness for estimation of changes in physical fitness of trained rowers during the training cycle was rather low. Such an opinion stems from the fact that the total error of these methods (range between 4.2-7.7% in female and 5.1-7.4% in male rowers) was higher than the real differences in VO2max values determined in direct measurements (between the first and the second examination maximal oxygen uptake rose by 3.0% in female rowers and decreased by 4.3% in male rowers).
