Carotid artery occlusion due to bacterial paranasal sinusitis.

Complications of paranasal sinusitis still continue to be a serious health problem. We present an orbita-related complication of sinusitis in a patient with diabetic ketoacidosis. It was not a rhinocerebral mucormycosis, but a bacterial sinusitis-induced development of left cavernous sinus thrombophlebitis and carotid artery occlusion. We discuss the diagnosis, surgical options, and clinical outcome.

Auditory evoked potentials in vitiligo patients.

There is convincing evidence that vitiligo is a systemic disorder influencing the whole pigmentary system, including melanocytes in the inner ear. Cochlear melanocytes and also melanin-containing cellular elements of the auditory system may be affected in vitiligo and interfere with the conduction of action potentials. We conducted a prospective clinical trial to determine hearing status and auditory evoked potentials in 50 patients affected by vitiligo and compared the results with those of 50 healthy controls. I, III, V latencies and amplitudes and I-III, III-V, I-V interpeak latencies were compared with each group. Statistical evaluation was accomplished using the t-test. With the exception of two subjects, all patients demonstrated normal audiological results. No statistically significant difference was noted between the study group and controls in regard to latencies, interpeak latencies and amplitudes. We conclude that auditory investigations supported by postmortem histopathological studies of the inner ear and brainstem may provide more accurate knowledge in vitiligo patients.

Comparison of amoxicillin with second and third generation cephalosporins in the treatment of acute otitis media.

The aim of the present study was to compare the efficacy and the tolerability of three different antibiotic regimens for the treatment of acute otitis media in paediatric patients. 75 children, age range 6 months-6 years, divided into three groups, were involved in the study, each group consisting of 25 randomly assigned children (Group 1, amoxicillin 40 mg/kg tid per os for 10 days; Group 2, cefuroxime axetil 30 mg/kg bid per os for 10 days; ceftriaxone 50 mg/kg single-dose i.m.). No statistically significant difference was noted in the clinical efficacy among the different groups. Although amoxicillin is the drug of choice in paediatric otitis media, single dose ceftriaxone might be considered as an interesting alternative regimen when ease of administration and cost of therapy are considered.

Importance of mastoid pneumatization on secretory otitis media.

Secretory otitis media is the most common middle ear disease of childhood. It heals spontaneously, by medical therapy or by minor surgical procedures in most of the cases. Sequelae such as retraction pockets and adhesive otitis that lead to cholesteatoma rarely occur, but initially it is hard to diagnose which patient will acquire a sequela. It is well known that mastoid pneumatization is poor in the patients who had complications like retraction pocket, adhesive otitis and cholesterol granuloma. The aim of this study was to determine if any relationship exists between mastoid pneumatization and secretory otitis media. Lateral mastoid X-rays of 47 children with secretory otitis media were evaluated. After 2 months of follow-up with medical therapy, 30 of the 47 patients needed ventilation tube insertion. The remaining 17 patients showed total recovery with medicines only. Control X-rays of the operated patients were taken 6 months after the operation. Mastoid pneumatizations of patients healed with medicine were compared with the operated patients. There were statistically significant differences between the mastoid pneumatizations of surgically and medically treated groups. In addition we observed a statistically significant difference between the mastoid areas of the preoperative and the postoperative X-rays. We concluded that mastoid pneumatization might be considered as a prognostic indicator in secretory otitis media. The estimated prognosis is poor when the mastoid pneumatization is poor.
