Objective To evaluate the outcomes of microdiscectomy for treatment of recurrent lumbar disc hemiations. Methods There were 18 cases of recurrent lumbar disc berniations accepted microdiscectomy (reoperation group), compared with 30 cases of primary lumbar microdiscectomy (primary group). Operating time, blood loss and length of hospital stay were compared between two groups. MacNab criteria were used to evaluate the outcomes. Results Operating time was a mean of 75 min in reoperation group, 52 min in primary group. Blood loss of reoperation group was 70 ml, 50ml in primary group. Length of hospital stay was 8.5d in reoperation group, 6.5d in primary group. There were one dural tear, two Ls root lesions and 5 more numbness reoperation group, but recovery all patients. There were one dural tear in primary group. 17 cases got follow-up mean 12.1 months in reoperation group and 29 cases in primary group mean 11.8 months. The results demonstrated 88.2% success rate in reoperation group and 93.1% in primary group. There was no significant dif-ference in two groups (P ＞ 0.05). Conclusion Outcomes of Lambar mierodisceetomy with mini-open for treatment of recurrent lumbar disc herniations are similar to primary lumbar mierodiscectomy.

Objective: To evaluate the effectiveness of family interventions among children with allergic rhinitis receiving immunotherapy, so as to provide insights into improvements of allergic rhinitis treatment. Methods: A total of 80 children with allergic rhinitis admitted to The First People's Hospital of Linping District from July 2018 to July 2021 were enrolled and randomly assigned into the control and intervention groups, of 40 participants in each group, and all children underwent immunotherapy. Children in the control group received routine interventions, while participants in the intervention group were given family interventions for 3 months, including health education, psychological counseling, and periodical follow-up. Parental awareness of allergic rhinitis was investigated using self-designed questionnaires, and the compliance to immunotherapy was evaluated. The clinical symptoms were evaluated using the symptom scores and the Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ), and the prognosis was evaluated using the Sino-Nasal Outcome Test-20 (SNOT-20). Results: There were no significant differences between the intervention and control groups in terms of gender, age, course of disease or disease severity (P>0.05). The scores for parental awareness of etiology [(9.56±0.25) vs. (7.45±0.85)], inducement factor [(8.84±0.62) vs. (6.76±1.36)], medication management [(9.56±0.25) vs. (7.97±0.85)] and daily life management of allergic rhinitis [(9.14±0.55) vs. (8.14±0.46)] were significantly higher in the intervention group than in the control group (P<0.05). The proportion of participants' compliance to immunotherapy was significantly higher in the intervention group than in the control group (92.50% vs. 75.00%, P<0.05). The scores for clinical symptoms [(3.12±0.94) vs. (3.96±1.23)], RQLQ score [(3.31±0.87) vs. (3.87±1.02)] and the SNOT-20 scores for nasal symptoms [(6.54±2.14) vs. (8.22±2.45)], sleep disorders [(4.11±0.58) vs. (5.24±1.03)], associated symptoms [(5.29±1.52) vs. (6.34±2.01)] and emotional consequences [(7.52±1.85) vs. (9.19±2.69)] were significantly lower in the intervention group than in the control group post-interventions (P<0.05). Conclusion Family interventions are effective to improve the compliance to immunotherapy, clinical symptoms, prognosis and quality of life among children with allergic rhinitis
