Immediate repair of the tympanic membrane to prevent persistent perforation after intentional removal of long-lasting tubes.

OBJECTIVE: Our purpose was to evaluate efficiency of immediate repair of the tympanic membrane perforation after intentional removal of the long-lasting tubes. METHODS: This study was done in 36 ears of 27 patients who had either Goode-T or Paparella-II silicone tube insertion due to chronic OME or ROM and tube removal. Only the ears in which tube removal was performed due to no longer need for middle ear ventilation were included to the study. After removal of the tube, the perforation edges were refreshed and Steri-Strip (3M) patch was adhered on the perforation site. Otoscopic, tympanometric and audiologic data were reported. RESULTS: Mean duration of the tube persistence was 49.58+/-11.94 months. It was found that there were two subgroups in the study group: those under regular follow-up (20 ears), and the ears which were out of regular follow-up (16 ears). Mean tube persistence times were 34.10 and 52.11 months in these subgroups, respectively (chi2-test, p=0.056). In six ears (16.67%), persistent perforation (PP) was found. PP rate (PPR) was higher in group-B (25%) than in group-A (10%) (chi2-test, p>0.1). The rest perforation was anteriorly marginal in five of six PP (83.33%). The PPR in the ears in which rest perforation was anteriorly marginal was 35.71% (5/14) while it was 4.54% (1/22) in the ears with central rest perforation (chi2-test, p<0.02). CONCLUSIONS: Even immediate repair of the perforation after removal of the long-lasting tubes resulted in a high PPR. The data in this study documented that this high PPR was associated with type and localisation of rest perforation and tube persistence time. Anteriorly, marginal perforations had about eight times higher risk of PP and longer tube persistence caused higher anterior marginal perforations after tube removal.

Surgical treatment of peripheral vertigo and vertiginous diseases.

Although our understanding of the mechanisms of vertigo and pathophysiology of vertiginous disorders has increased, diagnosis and treatment of various vertiginous diseases is challenging. The objective for the treatment of a vertiginous disease is to eliminate the underlying pathology either with maneuvers or drugs. In vertiginous diseases, surgery is performed either to eliminate the underlying pathologic event or to create stability in the incoming vestibular signals. It is not always possible to treat the underlying disease. Therefore, surgery is usually performed for the relief of vertigo. There are various surgical approaches used to treat a variety of vertiginous diseases. Selection of the approach depends on the type of vertiginous disease. This review mainly focuses on the current status and outcome of the surgeries used in the treatment of a variety of vertiginous diseases.

Progressive autosomal dominant optic atrophy and sensorineural hearing loss in a Turkish family.

PURPOSE: To describe the clinical features, mode of inheritance, and linkage analysis of ten affected members of a three-generation family with progressive optic atrophy and progressive hearing loss. MATERIALS AND METHODS: The proband, a 10-year-old boy, presented with progressive visual failure. Ten other members in his family, including his mother, half-sister, aunt, two uncles, grandfather, and some of the cousins, also had progressive visual loss and hearing loss. Six affected and four unaffected cases were examined in detail. Blood samples were drawn from 16 members for DNA extraction. Two loci previously described for optic atrophy were tested for linkage in the present family. RESULTS: The mode of inheritance was clearly autosomal dominant. Six members of the family were found to have progressive optic atrophy and hearing loss, both starting in the first decade of life. Total or red-green color blindness was detected in some patients. None of the members of this family showed evidence of other systemic disorders; however, four had blepharochalasis. No other cause could be found for the hearing or the visual loss. Linkage analysis excluded OPA1 and OPA2. CONCLUSION: The present Turkish family belongs to the group of individuals with autosomal dominantly inherited optic atrophies with hearing loss. Linkage analysis excluded OPA1 and OPA2, indicating that a novel gene defect underlies the disease in this family. Further genome-wide linkage analysis and identification of the disease-associated gene will help define the pathophysiology of this syndrome.

Low dose sultamicillin in acute sinusitis.

OBJECTIVES: To study the effectiveness of low dose sultamicillin in the treatment of acute sinusitis. METHODS: A total of 108 patients, between 16-56 years of age (mean 32.8), suffering from acute sinusitis took part in the trial. Patients received orally 2 x 375 mg sultamicillin, and compared with patients receiving 3 x 500 mg amoxicillin. The first control was made between the 5th and 7th days. A patient was considered clinically cured when all pretreatment signs and symptoms of infection were eliminated. Clinical improvement was defined as the partial disappearance of pretreatment signs and symptoms. In either result, study drugs were reconstituted for additional 5 days. Failure was defined as no change or worsening of signs and symptoms; and study drug was changed. The second control was made between 10-12th days, and the third was four weeks later. RESULTS: The clinical success (improvement + cure) rate was (17+11)/42 (66.6%) and (28+21)/66 (74.2%) for amoxicillin and sultamicillin respectively, at first control. All improved patients were cured at the second control. No significant side-effects were noted in either amoxicillin or sultamicillin treated patients. All side effects were gastrointestinal, 11.9% and 3.0% in the same order. CONCLUSIONS: Low dose sultamicillin was comparable to amoxicillin; sultamicillin has fewer side effects than amoxicillin (p>0.05).
