AI Article Synopsis
- A systematic review and meta-analysis were conducted to evaluate the efficacy of botulinum toxin A (BTX-A) injections in children with neurogenic bladder (NB) who do not respond to traditional antimuscarinic treatments.
- The review examined 19 studies, highlighting significant improvements, such as a 97.7 mL increase in cystometric capacity, a decrease in detrusor pressure by 25.2 cm HO, and a 73.4% incontinence resolution rate post-treatment.
- However, the studies varied in quality and design, lacking a placebo comparison and control groups, indicating that the evidence for BTX-A's effectiveness is not firmly established.
Article Abstract
Purpose: We performed a systematic review and meta-analysis to assess the current evidence on the effectiveness of botulinum toxin A (BTX-A) intradetrusor injections in paediatric NB patients who are resistant to antimuscarinic treatments.
Methods: A study was carried out on PubMed, Medline, and Embase with the search terms: ('neurogenic bladder' OR 'myelomeningocele') AND 'toxin' AND ('children' OR 'paediatric'). The PICOS framework guided the search strategy and selection of studies in line with the PRISMA guidelines. Research involving original data that examined BTX-A in paediatric patients with NB was included. Studies were independently chosen and data were extracted by two reviewers.
Results: Nineteen studies (one randomized controlled trial, six prospective studies, and 12 retrospective studies) that investigated the clinical application of BTX-A injections in children with NB were identified. None of the studies compared BTX-A to a placebo, and most lacked a control group. Results showed that maximal cystometric capacity increased by an average of 97.7 mL (34.1-162% increase) (95% confidence interval [CI] 59.6 to 135.8), while maximal detrusor pressure decreased by 25.2 cm HO (95% CI -39.7 to -10.7). Bladder compliance improved by 5.3 mL/cm HO (95% CI 2.9 to 7.8). After treatment, the average incontinence resolution rate among patients was 73.4%. Urinary tract infections were reported by 77 patients (13.6%).
Conclusions: BTX-A administered intradetrusorally enhances cystometric capacity, compliance, and maximum neurogenic detrusor overactivity in paediatric patients suffering from neurogenic bladder. Nonetheless, this conclusion lacks support from studies with a high level of evidence.

Excessive daytime sleepiness is a common finding among type 2 diabetes mellitus patients. However there is scarce data that shows the magnitude of excessive daytime sleepiness, & its association with type 2 diabetes mellitus. Hence, the study aimed to assess the prevalence of excessive daytime sleepiness and its associated factors among type 2 diabetes mellitus patients at Wolkite University Specialized Hospital.

E-cigarette/vaping-associated lung injury (EVALI) is strongly associated with vitamin E acetate and often occurs with concomitant tetrahydrocannabinol (THC) use. To uncover pathways associated with EVALI, we examined cytokines, transcriptomic signatures, and lipidomic profiles in bronchoalveolar lavage fluid (BALF) from THC-EVALI patients. At a single center, we prospectively enrolled mechanically ventilated patients with EVALI from THC-containing products (N = 4) and patients with non-vaping acute lung injury and airway controls (N = 5).
