[Oculomotor response to the vertical cephalic autorotatory test in patients with benign paroxistic positional vertigo of the posterior canal].

OBJECTIVE: To evaluate the eye movement response to the head auto-rotation test (HART) in the vertical plane in patients with benign paroxysmal positional vertigo. PATIENTS AND METHODS DESIGN: A transversal, descriptive study. SETTING UP: Outpatient clinic in a general Hospital. INDIVIDUALS: 34 posterior canal BPPV cases with a video-oculographic diagnosis, older than 18 years old, 7 of them were not able to perform the HART. INTERVENTION: HART was performed by a an electrooculographic system with simultaneous recording of head movement by an acelerometer in the vertical plane (Vorteq, Micromedical Instruments). The HART with eyes fixation was performed 3 times to determine its reliability. MAIN OUTCOME MEASURES: Gain, asymmetry and phase for the vertical VOR respectively. A statistical analysis was carried out to determine the test reliability and the number of individuals with an abnormal result. RESULTS: Gain is the only variable that showed a reproducible result in the HART for the active head movement at 1-2 Hz (test-retest reliability 0.83-0.89). The values of gain showed a moderate correlation at the frequencies 1-3 Hz (correlation 0.60-0.87). Asymmetry and phase were not reproducible variables (correlation < 0.55). Thirteen of 27 (48%) patients presented a decrease of the vertical gain, another 13 showed normal values and one case showed raised values. CONCLUSION: Gain is the only useful variable in the vertical HART. Forty-eight percent of patients with posterior canal BPPV have a reduced vertical gain, suggesting an impairment of inferior vestibular nerve function.

[Tonsillectomy by electrical dissection: risk factors of postoperative hemorrhage in children].

OBJECTIVE: To identify pre or intraoperative risk factors that could indicate a higher risk for post-tonsillectomy hemorrhage (PTH) in children undergoing electrocautery dissection. SET-UP: Primary referral hospital. DESIGN: A retrospective study of 163 post-tonsillectomy children comparing 7 cases of PTH with 156 cases with no PTH. SAMPLE: This study includes children under the age of 18 that underwent tonsillectomy by dissection between 1997 and 2000. OUTCOME PARAMETERS: Age, sex, height, weight, body mass index, hemoglobin level, hematocrit, platelet count activated partial thromboplastin time (APTT), fibrinogen, ASA index (physical state classification of the American Society of Anesthesiology) and type of hemostasis. RESULTS: Prevalence of PTH was 4.29% in the cohort sample. The risk of PTH in children following tonsillectomy by electrodissection is significantly increased in patients over 15 years of age (OR = 8.46, p = 0.04) and when ligatures are used for hemostasis (OR = 8.62, p = 0.02). Activated partial thromboplastin time > or = 32 seconds is marginally significant (OR = 7.82, p = 0.05). CONCLUSIONS: Our findings show that tonsillectomy by electrodissection has an increased risk of bleeding in older children and when ligatures are used for hemostasis.

[Anterior reconstructive glottecomy].

Shallow lesions of the glottis spreading to both sides of the middle line (T1b) have special characteristics under the viewpoint of its resection, because of the neighbourhood of the anterior commissure. Frontal and frontolateral techniques require a reconstructive step in order to avoid synechiae. The AA. report 35 cases with glottis reconstruction following several procedures: skin pedicled flap or epiglottoplasty. As the results almost the totality of the laryngectomees were "cured" after 5 years follow-up, and a high percentage of them free of tracheostomy tube.

[Evaluation of the treatment of benign paroxysmal positional vertigo with the DHI-S questionnaire].

Benign paroxysmal positional vertigo (BPPV) is a recurrent chronic disease and its handicap is usually underestimated. The aim of this study is to determine the impact of the treatment by Epley maneuver on short-term BPPV-related quality of life. Forty-two individuals with BPPV were included: 39 with posterior canal affected, 2 with the lateral canal and one with the anterior canal. Diagnosis was established if a consistent clinical history was found and Dix-Hallpike test (DHT) in cases with canal posterior involvement. Subjects with positive DHT were treated by a single Epley maneuver and were recommended to avoid supine for the next 48 hours. The BPPV relapses were investigated at 7th and 30th day post-treatment. BPPV-associated quality of life was evaluated by the Dizzness Handicap Inventory Short-form (DHI-S) at days 1st and 30th post-treatment. Total and partial scores for emotional, physical and functional subscales were compared by Wilcoxon test for paired samples. Dix-Hallpike test was found positive in el 59% individuals (23/39), and 41% cases did not required any treatment. Among 23 patients treated with Epley maneuver, DHT was found negative in 90% at 30th day follow-up. Mean and standard deviation of the total scores obtained in the DHI-S at the first day were 19.22 +/- 9.66 in the DHT positive-patients and 19.79 +/- 10.14 in the whole group (DHT positive or negative). These scores significantly decreased to 10.84 +/- 10.99 at 30 days post-treatment (p = 0.002 and p = 0.001, respectively). In conclusion, the DHI-S is a specific health questionnaire able to assess BPPV-related health and the effectiveness of treatment.
