Anal fistula is one of the most common diseases in anorectal surgery. The wound healing after surgery can affect the prognosis of patients. We conducted a protocol for systematic review and meta-analysis to assess the efficacy and safety of Chinese herbal medicine for reducing wound complications after anal fistula surgery. ⋯ This study may provide more convincing evidence to help clinicians make decisions when dealing with anal fistula patients after surgery.

Peripheral facial nerve palsy is a general term used to describe diseases that cause lower motor neuron lesions in the facial nerve. The most common cause of peripheral facial nerve palsy is idiopathic Bell's palsy (BP), accounting for 60% to 70% of all peripheral facial nerve palsy cases. Idiopathic BP is found in various medical conditions, such as ischemia, viral infection, and neuroinflammation; however, the specific pathophysiology remains unclear. Neuroimaging techniques help understand the neural mechanisms underlying various neurological disorders. In recent years, several studies have applied functional neuroimaging to investigate alterations of brain function in BP patients. However, the results have been inconsistent due to differences in methodology and quality. Moreover, systematic reviews of studies on functional neuroimaging for BP are insufficient. Therefore, the present study aims to verify the neural mechanisms of brain alterations and draw conclusions about the functional reorganization in patients with BP. ⋯ The aim of this study is to investigate functional reorganization of brain alterations in patients with BP. This review will improve the understanding of the neural mechanisms of BP based on the most recent publications through extensive data retrieval. If sufficient data are collected, a sensitivity analysis is performed to verify the robustness of the conclusions.

Since its introduction in 2013, the anterior quadratus lumborum (QL) block (QLB) has been widely used for analgesia in abdominal, pelvic, and hip surgeries, based on the assumption that it has analgesic effects on both incisional and visceral pain. However, the mechanism of the anterior QLB remains unclear, and the results of relevant studies are contradictory. This review aimed to summarize the dispersion patterns of injectates in anterior QLB. ⋯ Variability in the selection of injection sites relative to the anterior layer of the thoracolumbar fascia during anterior QLB implementation may explain the dispersion difference. The correct injection site of an anterior QLB is anterior to the QL muscle and between the QL muscle and the anterior layer of the thoracolumbar fascia. Further studies are needed to verify the injectate dispersion pattern during anterior QLB.

Centrally mediated abdominal pain syndrome (CAPS) is characterized by severe abdominal pain. Diagnosis of CAPS is still an exclusionary diagnosis, there remain no effective diagnostic biomarkers so far. Duloxetine is the major pharmacotherapy of CAPS, while some CAPS patients do not respond to duloxetine treatment. However, there is a lack of molecular markers to predict the efficacy of duloxetine. In our pilot study, we have found differential expression profiles of serum miRNAs between CAPS patients and healthy controls. Our study aims to explore the clinical characteristics, specific miRNAs in serum as diagnostic biomarkers of CAPS and predictive biomarkers of the efficacy of duloxetine. ⋯ Findings of study will provide the reliable basis for diagnosis and the predictor of duloxetine efficacy of CAPS. Importantly, findings grant patients a chance to benefit from treatment.

Case Reports
Two-year follow-up of a young male with possible acute hemorrhagic leukoencephalitis: A case report.
Acute hemorrhagic leukoencephalitis (AHLE) is a rare but fetal fulminant demyelinating disease of unknown etiology. It is commonly regarded as a severe variant of acute demyelinating encephalomyelitis (ADEM). Its rapid clinical deterioration and high mortality appeal to clinicians to attach importance to early diagnosis. Immunosuppressive therapy is the main management to attenuate the autoimmune process, but with varied response and prognosis. ⋯ AHLE presents distinctly from classical ADEM, and the situation may pose a diagnostic challenge. Clinicians should be vigilant in recognizing AHLE because of its rapid clinical deterioration and high mortality. We highlight the critical role of multimodal MRI, particularly susceptibility-weighted imaging (SWI) in the diagnosis of AHLE if cerebral biopsies are unavailable. Multiple courses of IVIG with MMF may be effective when early single pulse of corticosteroids fails. Individual who survives the initial insult may carry relatively good prognosis.
