Separation of Cr(III) and Cr(VI) using melamine-formaldehyde resin and determination of both species in water by FAAS

A method is described for the determination of Cr(VI) and total chromium by FAAS. Cr(VI) is separated from Cr(III) by adsorption on melamine-formaldehyde resin. After elution of Cr(VI) with 0.1 mol/l NaAc solution, it is analysed by FAAS. Total chromium is determined by FAAS after conversion of Cr(III) to Cr(VI) by oxidation with hydrogen peroxide, total Cr(VI) is concentrated as above. If the total concentration of chromium is sufficient, the determination can be directly made by FAAS. Cr(III) can then be calculated by subtracting Cr(VI) from the total Cr. This method was successfully applied to the determination of chromium in lake water.

Ultrasound examination of scrotal masses

The technique of renal time ultrasound of the scrotum is described. The examination was performed in 50 patients and 15 normal males at the Sahinbey Hospital. Given the clinical diagnosis ultrasound proved reliable in almost all cases. In this study ultrasonography of the scrotum has been found to be the most useful method demonstrating testicular diseases.

Hydatid disease of the kidney

OBJECTIVE

To define the clinical manifestations of echinococcal involvement of the urinary tract and to propose guidelines for treatment.

PATIENTS AND METHODS

A positive diagnosis of hydatid disease was made in seven patients and in all of these the cyst was located in the kidney only. The patients included four males and three females whose ages ranged from 6 to 56 years (mean 33.3).

RESULTS

Surgical treatment involved total nephrectomy in six patients and partial nephrectomy in one patient. There was no operative or post-operative mortality and all patients were cured of the disease.

CONCLUSION

Despite its rarity, hydatid disease should be considered in the differential diagnosis of space-occupying lesions of the urinary tract.

The Nesbit-Kelâmi procedure for congenital curvature of the erect penis. Report on 20 patients

Twenty patients with a congenital deformity of the erect penis were operated upon using the Nesbit-Kelâmi technique. Excellent results were obtained in all patients.

Epididymo-orchitis due to brucellosis

A diagnosis of epididymo-orchitis due to brucellosis was made in 13 patients between 1989 and 1991. Both testis and epididymis were involved in 8 patients, 3 had bilateral epididymo-orchitis and 2 presented with orchitis alone. Patients were treated with a combination of 200 mg doxycycline and 600 mg rifampicin daily for 6 weeks and complete resolution was achieved in 10.
