Cutaneous fistulas of the lumbar area are rarely diagnosed. The presented case concerned a 46-year old female patient who underwent surgical treatment in 2008, at the Department of General and Bariatric Surgery, and Emergency Medicine. After twelve months of ineffective conservative therapy of a purulent cutaneous fistula the patient was directed to the Department of Surgery for radical excision of the lesion. After performing additional diagnostic examinations the patient underwent planned surgery, including the complete excision of the fistula canal, which had no contact with the peritoneal cavity. Numerous deposits were observed in the lumen of the fistula. Chemical analysis of the abovementioned demonstrated a 100% content of calcium oxalate, characteristic of urolithiasis. The patient was discharged from the hospital on the eighth day after the operation in good general condition, and with a properly healing wound. Both patient history and examination were unable to definitely determine the cause of the fistula.

"Bile reflux" is a common term to denote a process of placing duodenal contents in the stomach and/or lower oesophagus. It is most often associated with functional or organic failure of the pylorus and is a not uncommon postoperative condition after pyloric section, resection or by-passing.Gastrotoxicity of the replaced small intestinal mixture leading to lesions in gastric mucosal barrier, is caused by an increased ability to reabsorb hydrogen ions along with migration of blood proteins and electrolytes towards lumen of the stomach. Consequently, histamine secretion becomes increased, leading to inflammatory and haemorrhagic changes or ulcer niches.The aim of the study was to demonstrate histological and microscopic changes in the gastric mucosa following reflux and to determine if long-term exposure to refluxed duodenal contents will produce tumorous changes in the organs tested.Material and methods. The study consisted of 25 mature female Wistar rats weighing 180-200 g. Bile reflux to the stomach was produced experimentally by surgical drainage. Final evaluation was performed after 55 weeks.Results. Findings were as follows: gastric changes were noted in basal and parietal cells, no tumorous foci were found in histological samples. Slight morphological changes can be caused by short periods of gastric mucosa exposure to the gastrotoxic small intestinal mixture.Conclusions. Endogenous bile acids cause morphological changes in the stomach mucosa of rats. In particular, these changes affect the ultrastructure of basal and parietal cells. No neoplastic foci were found in the examined organs.

The scope of this contribution was to investigate in detail an application of fly ash adsorbent for the removal of arsenite ions from à dilute solution. The experiments have been carried out using fly ash from black coal burning power plant "Siersza" and brown coal burning power plant "Turów" (Poland), which was wetted, then mixed and tumbled in the granulator with a small amount of cement to increase the mechanical strength of agglomerates. The measurements of arsenic adsorption from the aqueous solution were carried out in the flask (with shaking), as well as in the column (with circulation), in order to compare two different methods of contacting waste with adsorbent. The adsorption isotherms of arsenic were determined for granulated material, using the Freundlich model. Kinetics studies indicated that the sorption follows a pseudo-first-order (PFO) model (Lagergren) and the Elovich-type model.
