[Post-tonsillectomy hemostasis: a prospective, randomized, double-blind study comparing argon beam coagulation and monopolar electrocoagulation].

BACKGROUND: Argon Beam Coagulation (ABC) enables effective hemostasis and limited penetration depth of the coagulation zone. OBJECTIVE: This prospective, randomized, double-blind study compares ABC and monopolar electrocoagulation for post-tonsillectomy hemostasis. METHODS: Fifty patients undergoing elective tonsillectomy were enrolled into the study. Final hemostasis was achieved using ABC in one fossa and electrocoagulation in the other fossa, with the sides chosen at random. Postoperative bleeding, postoperative pain and the healing of the tonsillar fossa were compared for both methods. RESULTS: No differences in any of the outcome measures were found between the two methods. ABC was felt to be faster and more comfortable than monopolar electrocoagulation. CONCLUSION: ABC is an effective and comfortable method for post-tonsillectomy hemostasis.

Diagnostic evaluation of foreign body aspiration in children: a prospective study.

AIM: The aim of this study was to evaluate the yield of clinical symptoms, signs, and radiological studies in the diagnosis of foreign body aspiration (FBA) in children. METHODS: During the 2-year study, we performed on all children admitted to the pediatric department for suspected FBA a protocol that included the following: thorough medical history, physical examination, radiological studies (chest x-ray and fluoroscopy), and rigid bronchoscopy by a senior otolaryngologist. The yield of these measures for the diagnosis of FBA was evaluated. RESULTS: Foreign bodies were found in 56 (57%) of the 98 children with suspected FBA. Thirty-three (59%) children were boys and 23 (41%) girls (P < .05), with a mean age of 24 months (range, 8-84 months). Main symptoms in the children with FBA were the following: choking (76.8%), prolonged cough (14.3%), dyspnea (3.6%), and nonresolving pneumonia (1.8%). Physical examination, chest x-ray, and fluoroscopy findings were abnormal in 80.4%, 67.9%, and 46.9% of the children with FBA, respectively. The diagnostic yield of physical examination and radiological studies increased 24 hours after the event of FBA. In 45.2% of the children with positive history but with normal findings from physical examination and radiological studies, foreign bodies were found. Of the children with "doubtful" history, physical examination, chest x-ray, and fluoroscopy findings were abnormal in 58%, 38%, and 12.5%, respectively. Foreign bodies were found in 9.5% of these children. CONCLUSION: Medical history is the key for the diagnosis of FBA. Choking followed by an acute episode of coughing is the most common presentation of FBA. The yield of physical examination and radiological studies in the diagnosis of FBA is relatively low but is increased when the presentation is delayed and when history is doubtful. If FBA is suspected, bronchoscopy should be performed.

Mal de debarquement and posture: reduced reliance on vestibular and visual cues.

OBJECTIVE: The neural mismatch theory assumes that the intersensory conflicts leading to motion sickness are resolved by changes in the relative weighting of the various senses that contribute to orientation. If this sensory rearrangement persists after disembarkment, it might result in mal de debarquement (MD): ataxia and a rocking sensation sometimes felt after landing. The objective of the present study was to examine possible changes in sensory organization in naval crew members with differing susceptibility to MD with computerized dynamic posturography (CDP). STUDY DESIGN: Cross-sectional parallel-group design. METHODS: Seventeen subjects susceptible to MD (SMD) and 17 subjects nonsusceptible to MD (NSMD) (healthy male volunteers aged 18-22) participated in the study. CDP was performed twice with each subject, before and immediately after sailing, using the EquiTest system (NeuroCom, Inc., Clackamas, OR). RESULTS: The SMD group showed a significant reduction in their scores on sensory organization tests 3, 4, and 5 after sailing. Sensory pattern analysis revealed reduced use of inputs from the vestibular and visual systems to maintain balance. Prolonged latencies of the motor responses to unexpected pitch perturbations were also recorded in the postsailing CDP of the SMD group. Reduced performance on the presailing CDP task, which presents the greatest challenge to the vestibular system, was found to control for the presence of MD postsailing. CONCLUSIONS: The results show that MD is associated with postural instability, slower motor reflexes, and larger sways in response to abrupt changes in the body's center of gravity. These findings may be explained by under reliance on vestibular and visual inputs and increased dependence on the somatosensory system for the maintenance of balance.

Acute edema of the tongue: a life-threatening condition.

Acute macroglossia is rare, but may cause upper airway obstruction requiring emergency intervention. The cause of the problem is often obscure. Edema of the tongue may be due to angioedema or to allergy. We present several cases of acute edema of the tongue, in 3 cases causing life-threatening airway obstruction. Among these, we present the first case of acute enlargement of the tongue due to the ingestion of artichoke.

[Malignant teratocarcinosarcoma of the nose and paranasal sinuses].

Malignant teratocarcinosarcoma of the nasal cavity and the paranasal sinuses is a rare and invasive tumor. It is characterized by a mixture of mesenchymal and epithelial components, with cellular elements of a fetal nature. We describe in detail the first and only case in Israel of a patient with such a tumor. Only 40-50 such cases have been described in the medical literature. We have also reviewed the existing literature dealing with malignant teratocarcinosarcoma.
