Changes of distortion product otoacoustic emissions in the patients with iron deficient anaemia / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To observe the changes of distortion product otoacoustic emissions (DPOAE) in the patients with iron deficient anaemia (IDA).@*METHOD@#Sixty cases who were taken health physical examination at ZhaBei District Central Hospital were divided into two groups, the normal group (30 cases, 60 ears) and the IDA group (30 patients, 60 ears) depend on the results of examination of hemoglobin and serum ferritin. The changes of DPOAEs at 4 kHz were observed.@*RESULT@#A statistically significant decrease of DPOAE threshold level compared with the normal controls was seen at 4 kHz in the patients with IDA.@*CONCLUSION@#The decreased threshold level of DPOAE at 4 kHz in IDA patients should relate to sensorineural hearing loss directly.

The long-term effects of retrograde liberated highly selective vagotomy in treatment of duodenal ulcer / 中华外科杂志

<p><b>OBJECTIVE</b>To evaluate the long-term effects of retrograde liberated highly selective vagotomy (RLHSV) in the treatment of duodenal ulcer.</p><p><b>METHODS</b>Seventy patients with duodenal ulcers complicated by stenosis, bleeding, or perforation were operated on by retrograde liberated highly selective vagotomy. Among these patients, 61 had perforated duodenal ulcers, 6 bleeding and 3 stenosis.</p><p><b>RESULTS</b>Followed up for 30 to 120 months in 65 patients showed a recurrence rate 7.69% and no hemorrhage occurs. According to the modified Visick grading system, 56 patients (86.2%) were of Visick I, 4 (6.1%) of Visick II, 2 (3.0%) Visick III, 3 (4.6%) Visick IV, and (92.3%) Visick I or II.</p><p><b>CONCLUSIONS</b>This modified procedure is rapid, easy and radical operation with excellent long-term results. It can be considered an effective alternative for the treatment of duodenal ulcer with complication.</p>
