However, in the past few years, scattered reports of angioedema associated with ARBs have appeared in the medical literature. We performed a retrospective chart review from January 1, 1998, through June 30, 2003, and a review of the literature. During this time, we managed head and neck angioedema induced by ACEIs (n = 27) and ARBs (n = 4) in 31 patients. All of them had significant mucosal swelling, and in some of them dyspnea and dysphagia coexisted. The most frequently involved areas were the oral tongue (13 cases), uvula and soft palate (5 cases), and larynx, mouth floor, and lips (3 cases each). Angioedema may be a more common complication of ACEI and/or ARB use than originally thought. This complication may occur after long-term use of th...

The 'chameleonic' presentation of a mainly asymptomatic condition, the rarity of these lesions, the poor prognosis and the necessity of a highly specialized treatment are factors that should be seriously considered by the involved health provider. We present the case of a 75-year-old man who was referred to the Ear, Nose and Throat department. His symptoms were voice alteration and saliva drooling, progressively worsening during the last few weeks. The absence of pain was the reason for the delay of seeking medical care. The diagnosis was an oversized oral melanoma. This is an example of how the time of diagnosis and the evolution of a disease could be seriously influenced by patient's behavior. Melanomas arising from oral mucosa have poor prognosis unless they are discovered and treated early. The vigilance of the physicians is necessary to have success in this difficult task.

A third patient was studied who developed isolated glycosuria associated with lisinopril therapy. As in the two previously described patients, this patient had a normal serum glucose level, underlying hypertension, and onset of glycosuria between 2 and 16 weeks after initiation of therapy with an angiotensin-converting enzyme inhibitor. The patient had renal artery stenosis with elevated renin levels. Age, time until resolution of glycosuria, and a rise in serum creatinine level did not have a consistent relationship with glycosuria associated with angiotensin-converting enzyme inhibitor therapy. Since glycosuria was the only defect noted, without evidence of any other urinary solutes, angiotensin-converting enzyme inhibitors may exert an effect on the glucose-specific proximal tubule transport system.

Various surgical techniques have been advocated for the management of patients with vocal cord patients with vocal cord paralysis. Among these techniques, the individual use of laser CO2 arytenoidectomy and posterior cordotomy has gained wide acceptance. In this report, we describe our experience in

Experimental animal research protocol. University of Crete, School of Medicine, Medical Experimental Education and Research Center. Radiofrequency myringotomies were performed under general anesthesia on both ears of 20 rabbits. Mitomycin C (0.3 mg/ml) pledgets were applied in the right ears (study group) and saline pledgets in the left ears (control group). Animals were monitored using otomicroscopy weekly until myringotomy closure. Kaplan-Meier survival techniques were used to compare myringotomy patency time between the two sides. Radiofrequency myringotomy under general anesthesia on both ears of 20 rabbits. Myringotomy patency time. The mean patency time of the study group was 5.45 weeks (95% confidence interval, 5.185-5.715 weeks). The mean patency rate for the control side was 1.60 weeks (95% confidence interval, 1.38-1.82 weeks). The Breslow (ge...

Experimental animal research protocol. University of Crete, School of Medicine, Medical Experimental Education and Research Center. Bilateral myringotomies were performed under general anesthesia on 40 rabbits. LAT was performed on 20 animals (40 ears) and RFM on the remaining 20 animals (40 ears). MC (0.3 mg/mL) pledgets were applied to the right ears and saline pledgets to the left ears. Animals were monitored weekly using otomicroscopy until myringotomy closure. Kaplan-Meier survival techniques were used to compare myringotomy patency times. Under general anesthesia, bilateral LAT was performed on 20 rabbits and bilateral RFM on 20 rabbits. Myringotomy patency time. The mean patency times of the saline-treated ears were: 1.85 weeks (95% confidence interval [CI], 1.556-2.144 wk) for the LAT group and 1.70 weeks (95% CI, 1.494-1.906 wk) for the RFM group. This difference was not significant (p > 0.5). MC application significantly prolonged mean patency time (p < 0.0001) in both LAT and RFM groups. The mean patency times in the MC-treated ears were 5.45 weeks (95% CI, 5.226-5.674 wk) for the LAT group and 5.55 weeks (95% CI, 5.285-5.815 wk) for the RFM group. This difference was not significant (p > 0.5). There is no significant difference in myringotomy patency times between LAT and RFM techniques in rabbits, whereas MC significantly prolongs the patency rate of either technique.
