The clinical and bacteriological efficacy of ciprofloxacin was studied in three groups composed of 20 patients each, all of whom were affected by chronic otitis media in the acute stage. Ciprofloxacin was randomly administered according to the following schedules for 5 to 10 days: 250 mg orally twice a day (group A); 3 drops (250 micrograms/mL in saline solution) locally twice a day (group B); and both of the previous treatments twice a day (group C). A high percentage of favorable clinical response (100% and 95%) and bacteriological eradication (95% and 85%) was observed in groups B and C. A low percentage of patients (65% and 40%) were clinically and bacteriologically cured by the oral therapy (group A). No worsening of the audiometric and vestibular function was observed after local therapy. The results of this preliminary study suggest that the use of topical ciprofloxacin is effective in curing chronic otitis media, even when it is caused by Pseudomonas (47% of the total bacterial detections).

BackgroundMalignant tumours of minor salivary glands are uncommon, representing only 2-4% of all head and neck cancers. In the larynx, minor salivary gland tumours rarely occur and constitute less than 1% of laryngeal neoplasm. Most of the minor salivary gland tumours arise in the subglottis; however, they can also occur in the supraglottis, in the false vocal cords, aryepiglottic folds and caudal portion of the epiglottis. The most common type of malignant minor salivary gland tumour is adenoid cystic carcinoma.MethodsWe present a unusual case of adenoid cystic carcinoma of glottic-subglottic region in a 61-year-old woman. Follow-up endoscopy and laryngeal magnetic resonance imaging (MRI) at three years after treatment showed no recurrence of the tumour.ResultsThe diagnosis of glottic-subglottic adenoid cystic carcinoma should be considered in patients who are characterized by dyspnea, cough and stridor, but do not respond to pharmacologic approach.ConclusionsAdenoid cystic carcinoma is usually a very slow growing cancer, invested by an apparently normal laryngeal mucosa, so that it can show no clear symptoms for a long time. For these reasons the increasing number of diagnostic mistakes or late diagnosis that may be fatal in some cases.

On the basis of these results, GSH treatment could be considered for the nonsurgical management of chronic OME.

Due to their uremic state and altered host response induced by immunodepressive therapy, renal transplant recipients are particularly susceptible to infectious complications with high morbidity and mortality. We here report the results of a prospective study with 170 renal transplant patients, undertaken to evaluate the efficacy of ceftriaxone in the prevention of wound and early urinary tract infection. No wound infection was observed, however, 12 patients (7.1%) developed urinary tract infections. On the basis of these data, we recommend ceftriaxone prophylaxis as a safe and effective measure to prevent transplant wound infection and to reduce the incidence of postoperative urinary tract infection.

A once-square-inch-field-of-view mini gamma camera, whose first prototype was built by us in 1998 and given the name imaging probe (IP), was initially employed in sentinel lymph node (SLN) detection. This is probably the best way of learning how to use it. In the present work IP was used for SLN localization by a medical team that, after having been trained by the group of nuclear physicians of "La Sapienza" University who designed and first used the detector, used IP at their own hospital to 1) acquire experience for future use during surgery (a cooperative project on IP-radioguided orthopedic surgery is ongoing) and 2) start multicenter trials with IP. The SLN was identified and localized with IP and a non-imaging probe, Neoprobe 2000, in six patients with breast cancer who underwent lymphoscintigraphy for SLN biopsy. The operators who used Neoprobe and IP were blinded to each other's findings and to the results obtained with the large-field-of-view Anger camera that was used for lymphoscintigraphy. The Anger camera, IP and Neoprobe detected seven SLNs in six patients. The mean detection time was 2 mins 6 s (standard deviation (SD) 26 s) with IP, and 2 mins 18 s (SD 47 s) with Neoprobe 2000. The SLN that was most difficult to find was detected in 2 mins 56 s with IP and 3 mins 45 s with Neoprobe. The operators' subjective impression of having detected the SLN was "absolutely sure" for 7/7 nodes with IP and "absolutely sure" for 5/7 nodes with Neoprobe.
