Objectives: To assess the efficacy of topical sialogogue spray containing malic acid 1% for treating xerostomia. Methods: We searched PubMed, Cochrane Library, Embase, ClinicalTrials.gov and Web of Science databases. Literature search, screening, study selection, data collection, data extraction and assessment of bias risk were independently conducted by two reviewers. The study appraisal was performed by Cochrane Collaboration's tool for assessing bias risk. The systematic review registration number was PROSPERO-CRD42021241322. All statistical analyses were performed using Review Manager version 5.4.
Results:Five original articles involving 244 patients with xerostomia who received topical sialogogue spray (malic acid 1%) or placebo for two weeks were included in this review. Based on the questionnaire survey, the topical sialogogue spray (malic acid 1%) improved the symptoms of dry mouth significantly better than the placebo, which was reflected in the Dry Mouth Questionnaire (DMQ), Xerostomia Inventory (XI) and Visual Analogue Scale (VAS) scores. Regarding the increase in unstimulated and stimulated saliva flow rates, the intervention group was also better than the placebo group after a two-week course of treatment.
Conclusions:Although the included studies are limited, our results show that topical sialogogue spray (malic acid 1%) is an effective method for the treatment of xerostomia. Additional randomised controlled trials in the future are needed to provide highquality evidence of this therapy and to improve clinical practice guidelines.

The aim of this study was to prospectively evaluate the efficacy and tolerability of hyaluronic acid (HA) and meloxicam for the treatment of knee pain due to Kashin-Beck disease (KBD). A total of 162 patients with KBD-based knee pain were randomly assigned to treatment with a 3-week course of HA (n = 80) and a 12-week course of meloxicam (n = 82). Clinical assessments for each patient were made at 0 (baseline), 1, 2, 4, 8, and 12 weeks. The primary efficacy measure was visual analog scale (VAS) pain score. Second efficacy measures comprised the Western Ontario and McMaster Universities (WOMAC) A (pain), B (stiffness), and C (function) scores as well as patients' and physicians' global assessments. Tolerability was evaluated based on adverse events (AEs) and physician reporting. The VAS rapidly decreased in both groups over 12 weeks. The VAS improvement observed in HA group was lower at week 1 (p = 0.001) but better at weeks 8 and 12 (p < 0.001) than the meloxicam group, which were supported by the secondary variables of WOMAC A (p = 0.001) and WOMAC C (p < 0.001) scores and the global assessments of the patients and their physicians (p = 0.020 and 0.003, respectively). No serious AEs were reported, and the overall incidence of AEs among patients treated with meloxicam was higher than in patients treated with HA (p = 0.012). This study suggests that intra-articular injection of HA and administration of oral meloxicam should be efficacious and well tolerated in the treatment of knee pain due to KBD; the onset of action of meloxicam was faster than that of HA, whereas HA therapy resulted in a more prolonged increasing improvement of symptoms than meloxicam. In addition, HA treatment was likely superior to meloxicam with respect to tolerability. Other randomized double-blind studies are needed to confirm the findings of our open-label study.
Background:
There are limit studies about pediatric brain abscess in China. The aim of this study was to analyze clinical characteristics and outcomes of pediatric brain abscess in recent years in China.
Methods:
The clinical information of children with brain abscess hospitalized in Beijing Children’s Hospital between January 1, 2007 and December 31, 2016 were retrospectively reviewed.
Results:
Ninety-four children were enrolled in this study. A Streptococcus milleri group (13.8%) was identified as the most common causative organisms, followed by Staphylococcus aureus (6.4%). The overall mortality was 21.6%, with 50.0% of deaths happening in the first week after diagnosis. Long-term outcomes of 74 patients were assessed with Glasgow Outcome Scale–Extended Pediatric Reversion: 50 patients with a score of 1–2 (favorable outcome) and 24 patients with a score of 3–8 (unfavorable outcome). Patients with multiple abscesses (P = 0.029) and intraventricular rupture of brain abscess/hydrocephalus (P = 0.024) had higher risk of unfavorable outcomes.
Conclusions:
Brain abscess is a serious disease with high mortality in children; more aggressive treatments should be considered in the first week of diagnosis because of high risk of death, and for patients with multiple brain abscesses and intraventricular rupture of brain abscess/hydrocephalus because of their higher risk of unfavorable.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
