Removal of fluoride ions (F) from aqueous solutions using modified Turkish zeolite with quaternary ammonium.

The natural Turkish zeolite has been modified with hexadecyltrimethylammonium bromide (CTAB) for the elimination of fluoride (F) from aqueous solutions. The parent natural zeolite (NZ) and modified zeolite (MZ) have been characterized by Fourier transform infrared (FTIR) spectroscopy, thermogravimetric analysis (TGA), zeta potentials and Brunauer-Emmett-Teller (BET) method. The effect of pH, adsorbent dose, contact time, initial concentration and temperature on adsorption of fluoride ions onto modified zeolite (MZ) has been determined in batch experiments.

Traditional versus three-dimensional teaching of peritoneal embryogenesis: a comparative prospective study.

Introduction: Anatomy teaching is newly boosted by the development of interactive three-dimensional (3D) teaching techniques. Nevertheless, their superiority as teaching aids has never been demonstrated. The aim of this study was to compare 3D and traditional chalk teaching efficiency in terms of student memorization concerning peritoneal embryogenesis.

[Hydatid cysts of the spigelian lobe (segment I) of the liver: clinical and therapeutic particularities].

Objective: Hydatid cysts of the spigelian lobe, that is, segment I of the liver, are rare. We analyzed their clinical and therapeutic particularities.

Methods: We conducted a retrospective search for the hydatid cysts of the liver treated surgically in our department from January 1, 1994, through December 31, 2005.

[Cystic lymphangioma of the abdominal cavity. Report of 11 cases].

Objective: Our aim was to assess the epidemiological particularities, the circumstances of the diagnosis and the therapeutic indications of the cystic lymphangioma of the abdominal spaces.

Methods: Our retrospective and analytic survey concerns 11 cases of cystic lymphangioma of the abdominal spaces: mesentere 6 cases, epiploon 1 case, retroperitoneum 3 cases and under peritoneum 1 case. The incidence was of 1/2476 hospitalizations (0.

[Breast cancer in men].

Breast cancer in men is rare and most often occurs at or after the age of 60 years. Prognosis is poor when it is discovered at a late stage, as it often is in men, although it should be easier to detect because men have so little breast tissue. The causal mechanism appears to depend on hormone metabolism abnormalities related to elevated estrogen or prolactin levels.

[Retro-peritoneal liposarcoma. About 5 cases and revue of literature].

Liposarcomas are malignant mesenchymatous tumors developed from elements constituting the greasy tissue in various stages of differentiation. It is one of the most frequent mesenchymatous sarcomas. Retro-peritoneum is a privileged site of development in 12 to 15% of cases.

[Pyogenic liver abscesses: a study of 25 cases].

Objective: Our aim was to study the anatomo-clinic particularities and the therapeutic modes of the infectious abscesses of the liver.

Patients And Methods: Our retrospective study concerns 25 cases of the infectious abscesses of the liver collected on one period of 12 years from January 1992 to December 2003. They are 11 primitive abscesses and 14 secondary abscesses.

[Late post-operative adhesive small bowel occlusions. About 258 cases].

This retrospective study reports a series of 258 patients operated on for late developing post-operative adhesive occlusions. The impact of anterior interventions on these occlusions. The impact of anterior interventions on the occllusions as well as he clinical and paraclinical patterns are discussed before any approach to the different therapeutic aspects of this complication.

[Tuberculous encapsulating peritonitis. About 18 cases].

Our goal is to study the circumstances of diagnosis and the therapeutic modes of encapsulating peritonitis of tubercular origin. We report in this retrospective study 18 cases of encapsulating peritonitis of tubercular origin collected from 1982 to 2000. Symptoms and signs ere dominated by the general signs of tubercular nature, found isolated or in association with other, in 14 patients.

[Anastomotic ulcer after vagotomy for duodenal ulcer].

Between January 1981 and December 2000, 2609 patient underwent surgery for duodenal ulcer. 2274 underwent isolated vagotomy; 1590 had vagotomy associated with GI anastomosis. Only relapses of anostomic ulcers after vagotomy associated with gastrojejunal anastomosis were included in this study.

[Duodeno-pancreatic trauma. About 14 cases].

Through a series of 14 cases brought over a period of 12 years, we realized a retrospective, analytical and descriptive study of these traumatisms. We aimed to release recommendations to improve their management. It was 2 women and 12 men, whom mean age was 24.

[Intestinal Crohn disease: surgical aspects and predictive factors of risk of relapse. About 26 cases].

Crohn disease is an inflammatory bowel disease of which one cannot declare itself healed. It is a considerably invalidating disease, and surgery is necessary with more than 80% of patients during its long evolution. After a recent review of the literature, we wanted to contribute to the study of the predictive factors of risk of relapse among 26 patients operated for an intestinal Crohn disease during a period of 16 years, from 1986 till 2001.
