Compound oleum lithospermi in improving clinical symptoms of mild to moderate diaper dermatitis: a multicenter, open-labeled, randomized controlled clinical study / 中华皮肤科杂志

Objective:To evaluate clinical efficacy and safety of topical compound oleum lithospermi in the treatment of mild to moderate diaper dermatitis.Methods:A multicenter, randomized, positive-drug parallel-controlled clinical trial was conducted in 19 hospitals from July 2019 to August 2020. Children aged 0 - 12 months with mild to moderate diaper dermatitis were enrolled and randomly divided into 2 groups using a random number table: test group topically treated with compound oleum lithospermi, and control group topically treated with zinc oxide cream. The treatment was carried out 6 - 8 times a day for 7 days. Visits were scheduled on days 0 and 7, and total response rate and clinical healing time were evaluated. Changes in the dermatitis family impact (DFI) score were compared between the test group and control group, and adverse events were recorded. Statistical analysis was carried out by using independent-sample t test for normally distributed continuous data, Wilcoxon rank sum test for non-normally distributed continuous data, and chi-square test or Fisher′s exact test for unordered categorical data; survival curves were drawn, and log-rank test was used for comparisons between two groups. Results:A total of 343 children with diaper dermatitis were enrolled in this study. Among them, 31 children violated the protocol, so 312 were included in the per protocol set, including 157 in the test group and 155 in the control group, and all completed the visits on days 0 and 7. The total response rate was significantly higher in the test group (87.26%, 137/157) than in the control group (78.71%, 122/155; χ2 = 4.04, P = 0.044) . The clinical healing time was significantly shorter in the test group (5.33 days) than in the control group (6.13 days; χ2 = 4.67, P = 0.025) . After 7-day treatment, the DFI score significantly decreased in both the 2 groups compared with that before the treatment, but there was no significant difference in the DFI score between the 2 groups (test group: 4.02 ± 6.96, control group: 3.58 ± 5.90, Z = -0.39, P = 0.686) . The incidence of adverse events was 2.92% (5/171) and 5.45% (9/165) in the test group and control group respectively, and there was no significant difference between the 2 groups ( χ2 = 0.03, P = 0.865) . Conclusion:Compound oleum lithospermi can markedly reduce the clinical severity of diaper dermatitis, improve the total response rate, shorten the clinical treatment period, and improve the quality of life of children′s families with a favorable safety profile.

A randomized controlled clinical study on reverse-chopper prechop technique with phaco-and-chop technique for high myopia associated with hard nucleus cataract / 中华实验眼科杂志

Background The innovation of pre-chop technique lies in shortening surgery duration,reducing ultrasound power,and deseasing the loss of corneal endothelial cells (CECs).Objective This study was to compare the efficacy and safety of pre-chop technique using a reverse-chopper and phaco-and-chop phaco technique to super high myopia associated with hard nucleus cataract.Methods A prospective randomized-controlled-clinical interventional study was performed.Fourty eyes of 40 high myopia associated with cataract patients with Ⅲ-ⅣV degree of nucleus were enrolled in Beijing Tongren Hospital from March to September 2016.The patients were randomized into the pre-chop group and matched phaco-and-chop group according to random number table,and the self-made reverse chopper-assisted pre-chop phacoemulsification (phaco) surgery and phaco-and-chop phaco surgery were performed on the eyes of different groups,respectively.The phaco power,effective phaco duration and best corrected visual acuity (BCVA) were recorded and compared between the two groups to evaluate the efficacy,and the loss rate of corneal endothelial cells and eyes in different grades of cornea edema after operation were compared between the two groups to assess the safety of surgery procedure.Written informed consent from each patient was obtained prior to relevant examination and surgery.Results The surgery was finished smoothly in the eyes.The mean effective phaco duration was (47.30±11.29) seconds and (57.70± 14.51) seconds in the pre-chop group and phaco-andchop group,respectively,with a significant difference between them (t =-2.530,P =0.016).The BCVA was better at the seventh day after surgery in the pre-ehop group than that in the phaco-and-chop group (4.75t0.11 vs.4.67± 0.14),showing a significant difference between the two groups (t=2.147,P=0.038).In 1 month after surgery,the CECs loss rate was (10.82±3.77)％ in the pre-chop group,which was lower than (16.11±6.47)％ in the phacoand-chop group (t=-3.758,P=0.001).The number of the eyes with grade 2-3 of corneal edema in the pre-chop group was significantly decreased in comparison with the phaco-and-chop group 7 days after surgery (Z =11.822,P=0.008).Conclusions Compared with the conventional phaco-and-chop technique,reverse-chopper prechop technique appears to have a better efficacy and safety in phaco surgery for high-myopia associated with hard nuclear cataractous eyes.

Uso de dexametasona y salbutamol nebulizados en bronquiolitis aguda: estudio clínico comparativo / Comparative clinical study of dexamethasone vs. nebulized salbutamol in acute bronchiolitis

Objetivo: Evaluar la eficacia de salbutamol y dexametasona nebulizados comparados con salbutamol solo en pacientes con bronquiolitis aguda. Material y métodos: Estudio clínico controlado, aleatorizado, en pacientes de 1 a 18 meses de edad con diagnóstico de bronquiolitis aguda y evolución menor de tres días. Se asignaron dos grupos: 1) salbutamol (n = 24) o 2) salbutamol más dexametasona (n = 25) administrado por micronebulizaciones cada cuatro horas por 24 horas. Se midieron las frecuencias cardiaca y respiratoria, la gravedad del cuadro mediante el Respiratory Distress Assigment Index, el Silvermann-Andersen, saturación de O2 y tiempo de desaparición de la dificultad respiratoria y frecuencia de altas en 24 horas. Resultados: No se encontraron diferencias significativas entre los grupos de estudio, excepto en la frecuencia de altas hospitalarias en las primeras 24 horas, 75 vs 96 % p < 0.04 respectivamente. Conclusiones: La aplicación de salbutamol más dexametasona es más rápida para controlar la dificultad respiratoria en niños con bronquiolitis aguda en comparación con la aplicación de salbutamol solo.

OBJECTIVE: Asess the efficacy of nebulized salbutamol and dexamethasone compared with nebulized salbutamol, in patients with bronchiolitis. MATERIAL AND METHODS: A blinded clinical trial was performed with 49 patients between 1-18 months diagnosed with bronchiolitis with three days or less of disease evolution. Participant's parents signed an informed consent and patients did not receive prior medication. Patients were randomly assigned to two groups: nebulized salbutamol or salbutamol plus dexamethasone, which they received every four hours during twenty-four hours. We measured heart and respiratory rate; respiratory distress index, oxygen saturation, and Silverman Andersen scores. RESULTS: No significant differences were found between groups for treatment response; but the frequency of hospital release at 24 hrs was significant among groups; 75 vs 96 % respectively (p = 0.04). CONCLUSIONS: The administration of salbutamol plus dexamethasone is more effective in the control of respiratory distress in children with bronchiolitis compared with the use of salbutamol alone.
