Modelling the distributions of desalination brines from multiple sources along the Mediterranean coast of Israel.

We use numerical simulations to study the possible spatiotemporal effects of brine release from five desalination plants, located along the Israeli Mediterranean coastline. It is commonly believed that salinity anomalies, associated with brine discharge from desalination plants, causes effects which are confined to an area of several hundreds of meters from the discharge outfall. We show that discharging brine using diffusers produces small but robust salinity anomalies that propagate tens of kilometers as density currents (DCs).

Brucellosis with erythema nodosum-like manifestations diagnosed by isolated positivity of the ELISA test for anti-Brucella IgM.

Brucellosis is endemic in the Mediterranean area. In spite of the false negative results, the standard agglutination test remains the routine test for the diagnosis of brucellosis in southern Italy. We present a case of a patient with undulant fever and erythema nodosum-like skin lesions, with negative serum agglutination test, but isolated positivity of the ELISA test for anti-Brucella IgM.

Combined diagnostic imaging of transitional cell carcinoma of the upper urinary tract.

The case of a female patient with recurrent macroscopic hematuria and negative vesical and renal ultrasonography, is discussed. On urography a gross pyelocaliceal filling defect was visualized. Urographic findings were suggestive of the diagnosis of transitional cell carcinoma of the upper urinary.

[Antibiotics and kidney].

Renal excretion is the most important route of elimination for the majority of antibiotics, and some antibiotics may cause renal injury by direct and/or immunologic mechanisms. These conditions determine a dose relationship between antibiotic therapy and renal function. In this review we report some practical guidelines for the correct administration of antibiotics in patients with decreased renal function.

Abdominal or vaginal hysterectomy for enlarged uteri: a randomized clinical trial.

Objective: The purpose of this study was to compare advantages, disadvantages, and outcomes in patients who undergo vaginal or abdominal hysterectomy for enlarged symptomatic uteri.

Study Design: In a prospective, randomized study, 60 vaginal hysterectomies (study group) were compared with 59 abdominal hysterectomies (control group); all of the hysterectomies were performed for symptomatic uterine fibroids from January 1997 through December 2000. We excluded from the study the other common causes of hysterectomy such as prolapse, bleeding, adenomyosis, and endometrial or cervical carcinoma.
