Otomycosis usually requires long-term treatment and tends to recur. This study was performed on 87 patients with the clinical diagnosis of otomycosis and 20 controls in order to determine the pathogenic agents, predisposing factors and a cost-effective treatment. The predisposing factors included wearing head clothes (74.7 per cent), presence of dermatomycoses (34.5 per cent) and swimming (27.6 per cent). The most common pathogenic fungus was Aspergillus niger (44.8 per cent) in the otomycosis group. The only isolate was Candida albicans in the control group (2.5 per cent). We concluded that administration of four per cent boric acid solution in alcohol and frequent suction cleaning of the ear canal might be a cost-effective treatment for otomycosis since 77 per cent of the patients were treated effectively this way. Eighty per cent of the resistant cases had mixed fungal-bacterial infections, and 50 per cent of them had dermatomycoses. These resistant cases were treated by administration of tioconazole ointment.

: Amikacin is an aminoglycoside antibiotic used for many gram-negative bacterial infections like infections in the urinary tract, infections in brain, lungs and abdomen. Electrochemical determination of amikacin is a challenge in electroanalysis because it shows no voltammetric peak at the surface of bare electrodes. In this approach, a very simple and easy method for indirect voltammetric determination of amikacin presented in real samples. Gold nanoparticles were electrodeposited at the surface of glassy carbon electrode in constant potential. The effect of several parameters such as time and potential of deposition, pH and scan rates on signal were studied. The cathodic peak current of Au3+ decreased with increasing amikacin concentration. Quantitative analysis of amikacin was performed using differential pulse voltammetry by following cathodic peak current of gold ions. Two dynamic linear ranges of 1.0 × 10−8–1.0 × 10-7 M and 5.0 × 10−7–1.0 × 10-3 M were obtained and limit of detection was estimated 3.0× 10−9 M. The method was successfully determined amikacin in pharmaceutical preparation and human serum. The effect of several interference in determination of amikacin was also studied.
