Universal newborn hearing screening, a revolutionary diagnosis of deafness: real benefits and limitations.

The finding that early detection of permanent congenital childhood hearing loss produces worthwhile benefit in terms of improved speech and language provides the rationale for the universal screening of newborns. The aim of the present study is to collect the current evidence with regard to the efficacy, the results and outcomes of universal hearing screening programs. An extensive search of the literature was performed in Medline and other available database sources. Study selection was based on the evaluation of the protocols used and the assessment of their efficacy in the early diagnosis of congenital hearing impairment. The initial referral rate and the rate of false positives were also evaluated. A total of 676,043 screened children have been identified in 20 studies. The average initial referral rate in these studies was 3.89%. The initial referral rate varied from 0.6 to 16.7%. The lost-to-follow-up rates varied from 3.7 to 65%. Although universal hearing screening is now widely adopted, there are still some serious drawbacks and limitations. False positives rates remain considerably high when newborns are screened with TEOAE's. The combination of TEOAE's and a-ABR provides a significantly reduced referral rate. Close cooperation between audiological centres and maternity units and a dedicated secretariat team are of paramount importance with regard to the reliability and efficacy of universal hearing screening.

Juvenile nasopharyngeal angiofibroma stages I and II: a comparative study of surgical approaches.

OBJECTIVE: The aim of this study was to compare different surgical options used for removal of stages I and II juvenile nasopharyngeal angiofibromas (JNAs). Treatment morbidity was evaluated through blood loss, surgery duration, postoperative hospitalization and outcome. Moreover, an effort was made to explore the role and limits of endoscopic surgery. MATERIALS AND METHODS: 20 male patients (mean age 14.9 years) were treated for JNA using three different surgical approaches in the Department of Otolaryngology of the University of Athens between May 1998 and January 2007. 9 patients were managed using endoscopic approach, while 5 were treated through midfacial degloving. A transpalatal approach was performed in remaining 6 patients. Preoperative angiography with embolization was performed in all 9 patients who underwent endoscopic removal and in 3 patients treated by midfacial degloving technique. RESULTS: Findings demonstrated that endoscopic approach, assisted by preoperative embolization, lead to less intraoperative blood loss, shorter duration of surgical procedure, shorter length of hospital stay and no complications, compared with the conventional techniques. CONCLUSIONS: Our data suggest that with proper patient selection, endoscopic resection of stages I and II JNA, when it is performed after embolization of the feeding vessels, is remarkably bloodless and precise and may be preferable to traditional open approaches.

Administration of esmolol in microlaryngeal surgery for blunting the hemodynamic response during laryngoscopy and tracheal intubation in cigarette smokers.

OBJECTIVES: Cigarette smokers constitute a group of patients with an increased hemodynamic response to tracheal intubation. We studied the dose-response and side effects of bolus administration of esmolol hydrochloride in cigarette smokers undergoing elective microlaryngeal surgery, when esmolol was used for reducing the intense hemodynamic response to laryngoscopy and tracheal intubation. METHODS: We randomly allocated 165 patients (American Society of Anesthesiologists physical status classes I to III) to receive placebo (Eplac) or esmolol 1 mg/kg (E1) or 2 mg/kg (E2). The esmolol was given 2 minutes before laryngoscopy and tracheal intubation. The same anesthetic technique was used in all patients. Cardiovascular parameters were recorded every minute for the first 5 minutes and thereafter every 3 minutes. Bronchospasm, other side effects, and rescue esmolol treatment were noted during anesthesia. RESULTS: In group Eplac, significant increases (p < .05) in arterial blood pressure and heart rate were observed in the first 3 minutes after tracheal intubation. In group E1, significant increases (p < .05) in diastolic blood pressure were observed in the first 2 minutes after intubation. In group E2, no significant fluctuations were recorded in cardiovascular parameters after intubation. During surgery, 17% of the patients in group Eplac showed an increase in blood pressure and tachycardia. CONCLUSIONS: We conclude that esmolol administration of 2 mg/kg during induction of anesthesia in smokers provides hemodynamic stability after laryngoscopy and tracheal intubation with no severe side effects.

Preoperative administration of rofecoxib versus ketoprofen for pain relief after tonsillectomy.

OBJECTIVES: We evaluated the analgesic efficacy and the opioid-sparing effect of oral rofecoxib compared with intramuscular (IM) ketoprofen in tonsillectomy. METHODS: Seventy-seven adult patients were randomized into 2 groups: group R (n = 39), which received a single oral preoperative dose of rofecoxib 50 mg, and group K (n = 38), which received 2 IM doses of ketoprofen 100 mg (before surgery and after 12 hours). In both groups, additional IM meperidine hydrochloride 1 mg/kg was given. All patients received general anesthesia. A pain score (visual analog scale, 0 to 100) was assessed both at rest and during swallowing at 30 minutes and at 4, 8, 12, 16, and 24 hours after operation. If the pain score exceeded 40, patients were given meperidine as rescue analgesia. RESULTS: The pain scores during rest and swallowing in group R were significantly lower (p < .05) than those of group K at 4, 8, and 12 hours after operation. Meperidine was given as rescue medication in significantly more patients of group K (76%) than of group R (38%; p < .05). CONCLUSIONS: Oral premedication with rofecoxib seems to be more effective than use of ketoprofen in decreasing postoperative pain and the need for opioid rescue medication after elective tonsillectomy. Both drugs seem to be relatively safe as far as postoperative bleeding is concerned.

Inhalational anesthetic technique in microlaryngeal surgery: a comparison between sevoflurane-remifentanil and sevoflurane-alfentanil anesthesia.

We studied the effects of sevoflurane, remifentanil hydrochloride, and alfentanil anesthesia in terms of the hemodynamic responses and emergence characteristics of patients scheduled for elective microlaryngeal surgery. Sixty patients (ASA I to III) were randomly allocated into 2 groups: group S-R (sevoflurane-remifentanil) and group S-A (sevoflurane-alfentanil; 1:20 and 1:4 ratios of remifentanil to alfentanil for induction and maintenance of anesthesia, respectively; doses not strictly equipotent). The mean arterial pressure and heart rate were measured before and after induction of anesthesia, 1 and 3 minutes after endotracheal intubation, at the insertion of the operating laryngoscope, and every 3 minutes during surgery. The emergence times and side effects during the first 30 minutes after surgery were also recorded. The mean arterial pressure values at the insertion of the operating laryngoscope and throughout the procedure were significantly greater (p < .05) in group S-A than in group S-R. The emergence times and postoperative side effects did not differ, except for the greater pain score (p < .05) in group S-R. In conclusion, sevoflurane with remifentanil seems to maintain cardiovascular stability during microlaryngeal surgery more effectively than sevoflurane with alfentanil. Both anesthetic regimens seem to provide rapid and uneventful emergence.
