Screening biological traits and fluoride contents of native vegetations in arid environments to select efficiently fluoride-tolerant native plant species for in-situ phytoremediation.

High fluoride pollution has been detected in the surrounding soils of the coastal superphosphate industries in the Gulf of Gabes (Southeast of Tunisia). A study was conducted in vicinity of factories analysing plant functional traits combined with plant fluoride accumulation and soil metal concentrations aiming to screen more efficiently native plant species tolerant to this pollution. Aerial parts of 18 plant species out of the 10 most abundant species per site were harvested on two polluted sites of Gabes and Skhira at the vicinity of the factories and on the less polluted site of Smara.

[Early results of the surgical management of gastrointestinal stromal tumors (gist)--the experience of the 3rd surgical unit].

Unlabelled: This study provides a clinical and paraclinical algorithm of assessment of gastrointestinal stromal tumors (GIST), with the possibilities and limits of their current management. It is focused on defining an optimal imaging and anatomoclinic diagnosis protocol. In the absence of specific algorithm of surgical management, the study proposes an evaluation of possible histologic diagnosis and the indication for surgery, and the assessing the immediate results of thesurgical treatment.

[Distal pancreatectomy with spleen preservation in a pseudopapillary pancreatic tumor case].

Pseudopapillary pancreatic tumors represent about 1-2% of all exocrine pancreatic tumors, studies in the literature about this type of tumor is limited. We present a female patient of 18 years hospitalized for nonspecific abdominal symptoms, diagnosed with corporeal pancreatic tumor approximately 3-4 cm. It takes practice surgical distal pancreatectomy with spleen preservation, pathological examination revealing a pseudopapillary pancreatic tumor.

[Primary and secondary hepatic cancer--specifics of surgical treatment in correlation with disease stage].

Unlabelled: Given the necessity of increasing their resectability, there are evaluated the possibilities of surgical treatment for these types of hepatic cancer, in the context of dominant clinical presence of advanced hepatic tumors.

Material And Method: The study comprises 190 patients during 01.01.

[The ostomy support team. A reality for ostomates].

Stoma is a Greek word meaning mouth or opening. There are many types of surgical stomas and they may be raised on many areas of the abdominal wall. A stoma may be temporary or permanent, may be needed in any age group and may be sited on any part of the abdomen.

[Malignant peritoneal mesothelioma tumours. Evolution, treatment, prognosis].

Malignant mesothelioma of the peritoneum is a rare neoplasm with a rapidly fatal course. The median survival range is from 5 to 12 months in untreated cases with little improvement seen in patients receiving multimodality therapy. Although most cases occur in the fifth and sixth decades, peritoneal mesothelioma can be seen in any age group.

[Radiofrequency ablation in the multimodal treatment of liver metastases--preliminary report].

Unlabelled: Although the "gold standard" in the multimodal treatment of liver primary and secondary tumors is the surgical ablation, the rate of resection, despite the last decades advances, remains still low (10 - 20%). In addition, the interest for non-surgical ablation therapies is increasing. Among them, regional or systemic chemotherapy, intra-arterial radiotherapy as well as locally targeted therapies--cryotherapy, alcohol instillation and radiofrequency (RF) are the most valuable options as alternative to the surgical approach.

Features of pathological assessment in rectal cancer.

Rectal cancer diagnosis is established by collaboration between oncological surgeons, oncologists, pathologists and imaging specialists. By examining the macroscopic and microscopic aspect of the surgical specimen, the pathologist could provide the surgeon with information regarding the surgical procedure. Staging represents the clinical or pathological assessment of the extent of tumour spread.

[Malignant peritoneal mesothelioma].

Mesothelioma is a neoplasm originating from the mesothelial surface lining cells of the serous human cavities. It may involve the pleura, less frequently the peritoneum rarely, the pericardium, the tunica vaginalis testis and ovarian epithelium. Asbestos has been widely used in industry.

[Surgical resection in esophageal-gastric junction adenocarcinoma].

Between January 1999 and November 2005 there have been a number of 44 cases of cancers of the esophageal-gastric junction. Only 24 of them have been surgically removed. The carcinoma of the esophageal-gastric junction was defined on topographical and histological grounds, complemented by radiological, endoscopical and tomographical aspects.

[Can selective alpha-blockers help the spontaneous passage of the stones located in the uretero-bladder junction?].

The majority of ureteral stones at presentation in hospital are located within the distal ureter. Knowing that only half of the stones 4 to 5.9 mm will pass spontaneously, we tried to see: if we can facilitate this elimination for the stones smaller than 8 mm by selectve alpha-blockers (alfuzosin and tamsulosin) which induce relaxation of the smooth muscle of uretrotrigonal area and if there is any difference between these two drugs, concerning efficiency and tolerance.

[Completion gastrectomy associated with pancreaticoduodenectomy].

The authors present the case of a male patient, aged 56, operated (partial gastrectomy) for peptic ulcer 20 years ago, who is admitted for epigastric pain and distension, frequent vomiting, asthenia and weight loss. Physical examination, barium meal and upper digestive endoscopy with biopsy established the diagnosis of carcinoma of the gastric stump, due to malignant transformation of adenomatous polyps, with duodenal invasion. Completion of gastrectomy and pancreaticoduodenectomy was performed, with good postoperative results.

[Ureterolithotomy versus retrograde ureteroscopy for lumbar ureteral stone. A cost analysis].

Ureterolithotomy is considered to be the last option for treating a lumbar ureteric stone. The authors reviewed two cases with lumbar ureteric stones treated in january 2003, one by ureterolithotomy and one by retrograde ureteroscopy regarding the costs for hospitalisation, investigations and medication. Among the certain clinical advantages for the patients, including a smaller rate of complications, ureteroscopy is considerably cheaper than open surgery.
