Review
BACKGROUND
Intraoral adenoid cystic carcinoma (ACC) arising from minor salivary glands (MSG) is a rare malignancy associated with delayed diagnosis and unfavorable outcomes. This study aimed to comprehensively review ACC of MSGs, focusing on clinical characteristics, imaging modalities, treatment approaches, and long-term outcomes.
METHODS
A systematic search was conducted in PubMed, Web of Science, and MEDLINE databases to identify relevant articles reporting cases of ACC of MSGs between January 1997 and March 2023. The study was registered in PROSPERO (ID: CRD42023449478). A total of 10 studies that met the inclusion criteria were selected for critical review. In total, 902 patients were diagnosed with ACC of MSGs with an age range of 44.3 to 63 years, and an average age of 56.6 years. The female to male ratio ranges from 1:1 to 2.4:1. Regarding the primary site of ACC, the palate was the most common location, accounting for 30.5% to 83.3%, followed by the buccal mucosa, floor of the mouth, and lip and the retromolar area. For histology, the solid mass pattern was the most prevalent, seen in 95.2% of patients, followed by the cribriform pattern. Regarding treatment modalities, surgery was the most common approach, applied in 76.3% of cases, with a combination of surgery and radiotherapy used in 29.0% of cases. A smaller fraction, 3.2%, received a combination of surgery, chemotherapy, and radiotherapy, and 8.3% underwent radiotherapy alone. Local recurrence rates varied between 1% and 28.5%, and distant metastasis occurred in 18.2% to 33.3% of cases, predominantly to lymph nodes (14.5%). An analysis of overall survival across various stages and patient numbers indicated a 5-year survival rate of 68.0%. The findings of this study provide valuable insights for physicians in making treatment decisions and emphasize the need for ongoing research and collaborative clinical efforts to improve the management and outcomes of this challenging disease.
CONCLUSION
ACC of MSGs is a multifaceted condition typically manifesting as asymptomatic enlargement and ulceration. This disease is marked by distinct histopathological patterns and perineural invasion (PNI). Recognizing these distinctive aspects is key in shaping the treatment plan, which can range from surgical procedures to radiation therapy, chemotherapy, and evolving targeted treatments. Continuous research and collaborative clinical efforts remain critical for ongoing progress in the treatment and management of this challenging condition.

Review
Ultrasound-guided perineural hydrodissection (HD) is a novel technique that has been found to be effective in providing mechanical release of perineural adhesions and decompression of the nerve, reducing inflammation and edema and restoring its physiological function. It has a significant impact on chronic neuropathic pain (20 ± 4 weeks with VAS < 5 or VAS diminished by 2 points after the procedure). Carpal tunnel syndrome (CTS) is a common entrapment mononeuropathy, and its distribution is typically innervated by the median nerve. Patients with mild or moderate CTS may benefit from nonsurgical treatments or conservative therapies. This review was conducted following the preferred reporting items for systematic reviews and meta-analysis (PRISMA) statement guidelines. Four investigators assessed each title, abstract, and full-text article for eligibility, with disagreements being resolved by consensus with two experienced investigators. The qualitative assessment of the studies was carried out using the modified Oxford quality scoring system, also known as the modified Jadad score. Furthermore, risk of possible biases was assessed using the Cochrane collaboration tool. The results of this review suggest that US-guided HD is an innovative, effective, well-tolerated, and safe technique (11 out of 923 patients had collateral or side effects after the procedure). However, further studies comparing all drugs and with a larger sample population are required to determine the most effective substance.

: Pain management poses a significant challenge for patients experiencing vaso-occlusive crisis (VOC) in sickle cell disease (SCD). While opioid therapy is highly effective, its efficacy can be impeded by undesirable side effects. Local regional anesthesia (LRA), involving the deposition of a perineural anesthetic, provides a nociceptive blockade, local vasodilation and reduces the inflammatory response. However, the effectiveness of this therapeutic approach for VOC in SCD patients has been rarely reported up to now. The objective of this study was to assess the effectiveness of a single-shot local regional anesthesia (LRA) in reducing pain and consequently enhancing the management of severe vaso-occlusive crisis (VOC) in adults with sickle cell disease (SCD) unresponsive to conventional analgesic therapy. : We first collected consecutive episodes of VOC in critical care (ICU and emergency room) for six months in 2022 in a French University hospital with a large population of sickle cell patients in the West Indies population. We also performed a systematic review of the use of LRA in SCD. The primary outcome was defined using a numeric pain score (NPS) and/or percentage of change in opioid use. : We enrolled nine SCD adults (28 years old, 4 females) for ten episodes of VOC in whom LRA was used for pain management. Opioid reduction within the first 24 h post block was -75% (50 to 96%). Similarly, the NPS decreased from 9/10 pre-block to 0-1/10 post-block. Five studies, including one case series with three patients and four case reports, employed peripheral nerve blocks for regional anesthesia. In general, local regional anesthesia (LRA) exhibited a reduction in pain and symptoms, along with a decrease in opioid consumption post-procedure. : LRA improves pain scores, reduces opioid consumption in SCD patients with refractory pain, and may mitigate opioid-related side effects while facilitating the transition to oral analgesics. Furthermore, LRA is a safe and effective procedure.

Meta-Analysis
The significance of perineural invasion (PNI) present in penile cancer (PC) is controversial. In order to clarify the predictive role of PNI in the inguinal lymph node (ILN) metastases (ILNM) and oncologic outcome of patients, we performed this meta-analysis and systematic review. The search of PubMed, Embase, and Web of Science was conducted for appropriate studies, up to 20 January 2018. The pooled odds ratio (OR) and hazard ratio (HR) with their 95% confidence interval (CI) were applied to evaluate the difference in ILNM and oncologic outcome between patients present with PNI and those who were absent. A total of 298 in 1001 patients present with PNI were identified in current meta-analysis and systematic review. Significant difference was observed in ILNM between PNI present and absent from patients with PC (OR = 2.98, 95% CI = 2.00-4.45). Patients present with PNI had a worse cancer-specific survival (CSS) (HR = 3.58, 95% CI = 1.70-7.55) and a higher cancer-specific mortality (CSM) (HR = 2.20, 95% CI = 1.06-3.82) than those cases without PNI. This meta-analysis and systematic review demonstrated the predictive role of PNI in ILNM, CSS, and CSM for PC patients.

Meta-Analysis
BACKGROUND
Perineural (PN) dexamethasone (DEX) administration can prolong the analgesic time of a brachial plexus block. However, its efficacy and safety are controversial due to its off-label use and different routes of administration.
OBJECTIVES
This meta-analysis aimed to assess the safety and efficacy of PN versus intravenous (IV) dexamethasone.
STUDY DESIGN
Systematic review and meta-analysis of randomized controlled trials (RCTs).
SETTING
Relevant studies were found through a comprehensive literature search of PubMed, Web of Science, Ovid, EMBASE, and the Cochrane Library (from the inception until January 2020).
METHODS
According to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, this meta-analysis was conducted to identify RCTs comparing PN and IV dexamethasone in brachial plexus block. A randomized effect model was used in the meta-analysis and the subgroup analysis was performed with adrenaline stratification. The quality of evidence and the strength of recommendations were graded by GradePro version 3.6.1.
RESULTS
Twelve RCTs with a total of 1,345 subjects were included. We found that PN dexamethasone could prolong the duration of analgesia (mean difference [MD]: 131.82 minutes, 95% confidence interval [CI] [38.96, 224.68], I2 = 82%, P = 0.005), motor block (MD: 218.85 minutes, 95% CI [113.65,324.05], I2 = 72%, P < 0.0001) and sensory block (MD: 209.57 minutes, 95% CI [72.64, 346.50], I2 = 87%, P = 0.003) in the main analysis with significant difference. In the absence of epinephrine, there were no significant differences between PN dexamethasone and IV dexamethasone. Except for adverse-effects, no significant differences were observed in secondary outcomes. PN dexamethasone had slightly higher adverse-effects; however, these could be altered if a sensitivity analysis was conducted.
LIMITATIONS
There was high heterogeneity among included studies.
CONCLUSIONS
PN dexamethasone can prolong the duration of analgesia, sensory block, and motor block, when compared with IV dexamethasone. In a subgroup analysis without epinephrine, the 2 routes of administration were equivalent to topical anesthesia. There were no differences in secondary outcomes, except for adverse effects, which could be altered if a sensitivity analysis was conducted. Therefore, despite the advantages of PN dexamethasone, caution is needed due to its off-label character. While the results of this study are promising, additional large and well-designed RCTs are needed to validate these initial findings and their implications.

Review
Hallux valgus repair is associated with moderate-to-severe postoperative pain. The aim of this systematic review was to assess the available literature and develop recommendations for optimal pain management after hallux valgus repair. A systematic review using PROcedure SPECific Postoperative Pain ManagemenT (PROSPECT) methodology was undertaken. Randomized controlled trials (RCTs) published in the English language from inception of database to December 2019 assessing postoperative pain using analgesic, anesthetic, and surgical interventions were identified from MEDLINE, EMBASE, and Cochrane Database, among others. Of the 836 RCTs identified, 55 RCTs and 1 systematic review met our inclusion criteria. Interventions that improved postoperative pain relief included paracetamol and non-steroidal anti-inflammatory drugs or cyclo-oxygenase-2 selective inhibitors, systemic steroids, ankle block, and local anesthetic wound infiltration. Insufficient evidence was found for the use of gabapentinoids or wound infiltration with extended release bupivacaine or dexamethasone. Conflicting evidence was found for percutaneous chevron osteotomy. No evidence was found for homeopathic preparation, continuous local anesthetic wound infusion, clonidine and fentanyl as sciatic perineural adjuncts, bioabsorbable magnesium screws, and plaster slippers. No studies of sciatic nerve block met the inclusion criteria for PROSPECT methodology due to a wider scope of included surgical procedures or the lack of a control (no block) group. The analgesic regimen for hallux valgus repair should include, in the absence of contraindication, paracetamol and a non-steroidal anti-inflammatory drug or cyclo-oxygenase-2 selective inhibitor administered preoperatively or intraoperatively and continued postoperatively, along with systemic steroids, and postoperative opioids for rescue analgesia.

BACKGROUND
Perineural invasion (PNI) is a malignant metastatic mode of tumors and has been reported in many tumors including esophageal cancer (EC). However, the role of PNI in EC has been reported differently. This systematic review and meta-analysis aims to focus on the role of PNI in EC.
METHODS
Eight databases of CNKI, VIP, Wanfang, Scopus, Wiley, ISI, PubMed, and EBSCO are used for literature search. The association of PNI with gender, pathological stages of T and N (pT and pN), lymphovascular invasion (LVI), lymph node metastasis, 5-year overall survival (OS), and 5-year disease-free survival (DFS) was examined in the meta-analysis by Revman5.0 Software. The pooled OR/HR and 95% CI were used to assess the risk and prognostic value.
RESULTS
Sixty-nine published studies were screened for analysis of PNI in EC. The incidence of PNI in esophageal squamous carcinoma (ESCC) and esophageal adenocarcinoma (EAC) was different, but not statistically significant ( 0.05). The PNI-positive patients had a significantly higher risk of pT stage (OR = 3.85, 95% CI = 2.45-6.05, < 0.00001), pN stage (OR = 1.86, 95% CI = 1.52-2.28, < 0.00001), LVI (OR = 2.44, 95% CI = 1.55-3.85, = 0.0001), and lymph node metastasis (OR = 2.87, 95% CI = 1.56-5.29, = 0.0007). Furthermore, the cumulative analysis revealed a significant correlation between PNI and poor OS (HR = 1.37, 95% CI = 1.24-1.51, < 0.0001), as well as poor DFS (HR = 1.55, 95% CI = 1.38-1.74, < 0.0001).
CONCLUSION
PNI occurrence is significantly related to tumor stage, LVI, lymph node metastasis, OS, and DFS. These results indicate that PNI can serve as an indicator of high malignant degree and poor prognosis in EC.

Meta-Analysis
OBJECTIVE
We conducted a meta-analysis and systematic review to compare the efficacy of perineural vs. intravenous dexmedetomidine as local anesthetic adjuvant.
MATERIALS AND METHODS
Two researchers searched MEDLINE, OVID, PubMed, Embase, Cochrane Central, Web of Science and Wanfang data for randomized controlled trials comparing the effect of intravenous vs. perineural injection of dexmedetomidine as a local anesthetic adjuvant in prolongation of analgesia for peripheral nerve block, without any language restrictions.
RESULTS
We identified 14 randomized controlled trials. The results revealed that the duration of analgesia [Standard mean difference (SMD): -0.55, 95% CI, (-1.05, -0.05) p=0.032, I2=85.4%] and the duration of sensory block [SMD: -2.68, 95% CI, (-4.53, -0.83) p=0.004, I2=97.3%], were significantly longer, the onset time of motor block [SMD: 0.65, 95% CI, (0.02, 1.27) p=0.043, I2=85.0%] was shorter in the perineural dexmedetomidine group, when compared with the systematic dexmedetomidine group. There was no significant difference in the duration of motor block [SMD: -0.32, 95% CI, (-1.11, -0.46) p=0.416, I2=89.8%] and the onset time of sensory block [SMD: 0.09, 95% CI, (-0.33, 0.52) p=0.668, I2=59.9%] between the two groups. Meanwhile, perineural dexmedetomidine reduced analgesic consumption in 24 hours [SMD: 0.43, 95% CI, (0.06, 0.80) p=0.022, I2=58.7%] compared with the intravenous dexmedetomidine group.
CONCLUSIONS
Our meta-analysis currently generates the evidence that perineural dexmedetomidine administration offers advantages not only in prolonging the duration of analgesia and sensory block, but also in shortening the onset time of motor block, when compared with the intravenous administration.

OBJECTIVE
To evaluate the consistencies and inconsistencies between distal cholangiocarcinoma (DCCA) and pancreatic ductal adenocarcinoma (PDCA) regarding their biological features and long-term prognosis.
METHODS
PubMed, the Cochrane Library, and EMBASE were searched to find comparative studies between DCCA and PDCA. RevMan5.3 and Stata 13.0 software were used for the statistical analyses.
RESULTS
Eleven studies with 4,698 patients with DCCA and 100,629 patients with PDCA were identified. Pooled results indicated that patients with DCCA had a significantly higher rate of preoperative jaundice (p = 0.0003). Lymphatic metastasis (p < 0.00001), vascular invasion (p < 0.0001), and peri-neural invasion (p = 0.005) were more frequently detected in patients with PDCA. After curative pancreaticoduodenectomy (PD), a significantly higher R0 rate (p < 0.0001) and significantly smaller tumor size (p < 0.00001) were detected in patients with DCCA. Patients with DCCA had a more favorable overall survival (OS) (p < 0.00001) and disease-free survival (DFS) (p = 0.005) than patients with PDCA. However, postoperative morbidities (p = 0.02), especially postoperative pancreatic fistula (POPF) (p < 0.00001), more frequently occurred in DCCA.
CONCLUSION
Patients with DCCA had more favorable tumor pathological features and long-term prognosis than patients with PDCA. An early diagnosis more frequently occurred in patients with DCCA. However, postoperative complications, especially POPF, were more frequently observed in patients with DCCA.

Review
Pathology reporting is evolving from a traditional narrative report to a more structured synoptic report. Narrative reporting can cause misinterpretation due to lack of information and structure. In this systematic review, we evaluate the impact of synoptic reporting on completeness of pathology reports and quality of pathology evaluation for solid tumours. Pubmed, Embase and Cochrane databases were systematically searched to identify studies describing the effect of synoptic reporting implementation on completeness of reporting and quality of pathology evaluation of solid malignant tumours. Thirty-three studies met the inclusion criteria. All studies, except one, reported an increased overall completeness of pathology reports after introduction of synoptic reporting (SR). Most frequently studied cancers were breast (n = 9) and colorectal cancer (n = 16). For breast cancer, narrative reports adequately described 'tumour type' and 'nodal status'. Synoptic reporting resulted in improved description of 'resection margins', 'DCIS size', 'location' and 'presence of calcifications'. For colorectal cancer, narrative reports adequately reported 'tumour type', 'invasion depth', 'lymph node counts' and 'nodal status'. Synoptic reporting resulted in increased reporting of 'circumferential margin', 'resection margin', 'perineural invasion' and 'lymphovascular invasion'. In addition, increased numbers of reported lymph nodes were found in synoptic reports. Narrative reports of other cancer types described the traditional parameters adequately, whereas for 'resection margins' and '(lympho)vascular/perineural invasion', implementation of synoptic reporting was necessary. Synoptic reporting results in improved reporting of clinical relevant data. Demonstration of clinical impact of this improved method of pathology reporting is required for successful introduction and implementation in daily pathology practice.
