BACKGROUND
Miller Fisher syndrome (MFS) is a subtype of Guillain-Barré syndrome (GBS) which is characterized by the three components of ophthalmoplegia, ataxia, and areflexia. Some studies reported MFS as an adverse effect of the COVID-19 vaccination. We aimed to have a detailed evaluation on demographic, clinical, and para-clinical characteristics of subjects with MFS after receiving COVID-19 vaccines.
MATERIALS AND METHODS
A thorough search strategy was designed, and PubMed, Web of Science, and Embase were searched to find relevant articles. Each screening step was done by twice, and in case of disagreement, another author was consulted. Data on different characteristics of the patients and types of the vaccines were extracted. The risk of bias of the studies was assessed using Joanna Briggs Institute (JBI) tools.
RESULTS
In this study, 15 patients were identified from 15 case studies. The median age of the patients was 64, ranging from 24 to 84 years. Ten patients (66.6%) were men and Pfizer made up 46.7% of the injected vaccines. The median time from vaccination to symptoms onset was 14 days and varied from 7 to 35 days. Furthermore,14 patients had ocular signs, and 78.3% (11/14) of ocular manifestations were bilateral. Among neurological conditions, other than MFS triad, facial weakness or facial nerve palsy was the most frequently reported side effect that was in seven (46.7%) subjects. Intravenous immunoglobulin (IVIg) was the most frequently used treatment (13/15, 86.7%). Six patients received 0.4 g/kg and the four had 2 g/kg. Patients stayed at the hospital from five to 51 days. No fatal outcomes were reported. Finally, 40.0% (4/15) of patients completely recovered, and the rest experienced improvement.
CONCLUSION
MFS after COVID-19 immunization has favorable outcomes and good prognosis. However, long interval from disease presentation to treatment in some studies indicates that more attention should be paid to MFS as the adverse effect of the vaccination. Due to the challenging diagnosis, MFS must be considered in list of the differential diagnosis in patients with a history of recent COVID-19 vaccination and any of the ocular complaints, ataxia, or loss of reflexes, specially for male patients in their 60s and 70s.

Journal of Hand Surgery Global Online Jan 2024This study aimed to evaluate the safety and effectiveness of mini-open carpal tunnel release (mOCTR) using best-evidence synthesis methods.
PURPOSE
This study aimed to evaluate the safety and effectiveness of mini-open carpal tunnel release (mOCTR) using best-evidence synthesis methods.
METHODS
We systematically searched for prospective studies published from January 2013 to July 2023 that reported outcomes from a minimum of 50 mOCTR cases. The outcomes included Quick Disabilities of the Arm, Shoulder, and Hand Questionnaire, Boston Carpal Tunnel Questionnaire Symptom Severity Scale (BCTQ-SSS) and Functional Status Scale (BCTQ-FSS), pain visual analog scale (VAS), complication rate, and reoperation rate. Data analysis was performed using a random-effects meta-analysis, with metaregression to identify the associations between patient- and study-level factors with surgical outcomes.
RESULTS
The meta-analysis included 23 studies with 2,303 patients followed for median durations ranging from 6 to 12 months depending on the outcome. Mini-open carpal tunnel release resulted in statistically significant and clinically important improvements in Quick Disabilities of the Arm, Shoulder, and Hand Questionnaire (mean difference = -25.5; 95% confidence interval [CI]: -36.4 to -14.5; < .001), BCTQ-SSS (mean difference = -2.2; 95% CI: -2.5 to -1.9; < .001), BCTQ-FSS (mean difference = -2.1; 95% CI: -2.4 to -1.7; < .001), and pain VAS (mean difference = -5.1; 95% CI: -6.2 to -4.1; < .001). The sole predictor of improvement in BCTQ-SSS, BCTQ-FSS, and pain VAS was a higher preoperative score for the respective variable (all < .001). The risk of complications (mainly short-term pillar pain or scar complications) was 8.9% (95% CI: 4.0%-13.8%) and increased with longer incision lengths ( = .008). Revision carpal tunnel release was performed in 0.6% (95% CI: 0.1%-1.0%) of the cases during follow-up. No cases of median nerve transection were reported.
CONCLUSIONS
Based on a best-evidence meta-analysis of contemporary studies, mOCTR significantly improved function and pain, with a relatively low risk of mainly temporary complications. Patient outcomes after mOCTR were influenced by patient symptomatology and surgical incision length.
CLINICAL RELEVANCE
Mini-open carpal tunnel release is an effective surgical option that significantly improves symptoms and function, especially for patients with more severe baseline dysfunction. Surgeons should use the shortest incision that allows adequate visualization to safely divide the transverse carpal ligament.

Meta-Analysis
OBJECTIVE
Leptomeningeal metastasis (LM) is associated with altered CSF flow dynamics in 50%-70% of patients. Approximately 1%-5% of patients develop symptomatic LM-associated hydrocephalus (LM-H), which adversely impacts quality of life (QOL), functional status, and overall survival (OS). There is equipoise for CSF diversion procedures in LM-H. This systematic review and meta-analysis aimed to assess the effect of CSF diversion on OS and QOL in this context.
METHODS
This systematic review was conducted according to the PRISMA guidelines. PubMed/Medline, Embase, Web of Science, and Scopus were searched for articles that evaluated the role of CSF diversion for LM-H due to systemic cancer in adult patients. A meta-analysis was conducted using random effects models, with mean differences and 95% CIs reported. Bias was assessed using the Risk of Bias in Nonrandomized Studies of Interventions (ROBINS-I) tool.
RESULTS
Ten eligible studies with a total of 494 patients were included. Two studies reported multivariate HRs for median OS, suggesting no significant effect of shunting on OS (pooled HR 0.42, 95% CI 0.09-1.94, p = 0.27). A difference between preoperative and postoperative Karnofsky Performance Status of mean 17.6 points (95% CI 10.44-24.68, p < 0.0001) was calculated from 4 studies. Across all studies, a symptomatic improvement rate of 67%-100% was observed, with high rates of improvement for headaches and nausea and lower rates for cranial nerve palsies. Complication rates across 9 studies ranged from 0% to 21.1%.
CONCLUSIONS
Based on the present findings, shunting does not improve OS but does relieve symptoms, suggesting that individuals who exhibit certain symptoms should be considered for CSF diversion. The present findings prompt the generation of a standardized decision-making tool and a critical analysis of the individual patient risk-benefit ratio. Implementation of these will optimize surgical management of LM-H patients.

Review
BACKGROUND
Pudendal nerve entrapment (PNE) is an underdiagnosed condition affecting a spectrum of pelvic functions, primarily pain, as outlined by Nantes diagnostic criteria. Although numerous surgical decompression techniques are available for its management, consensus on efficacy and safety is lacking. This study conducts a systematic review and meta-analysis to assess the efficacy and complication rates of the main surgical decompression techniques.
METHODS
A comprehensive literature search was conducted in PubMed®, Embase®, Web of Science®, and ClinicalTrails.gov® on 19th of April 2023. Initial screening involved title and abstract evaluation, with subsequent retrieval and assessment of abstracts and full-text articles. Studies assessing pain outcomes before and after surgical release of the pudendal nerve were included. Studies without full-text, focusing on diagnostic methods or with outcomes relating solely to LUTS, digestive symptoms, or sexual dysfunction, were excluded. Risk of bias assessement was conducted using the National Institute of Health (NIH) Study Quality Assessment tool. Studies were categorized based on three surgical techniques: perineal, transgluteal, and laparoscopic transperitoneal. Random-effects meta-analysis with subgroup analysis were used. Meta-regression analyses were conducted to investigate the influence of covariates on the observed outcomes.
RESULTS
Nineteen studies, comprising 810 patients, were included. The overall significant pain relief rate across all techniques was estimated at 0.67 (95% CI 0.54 to 0.78) with considerable heterogeneity (I = 80.4%). Subgroup analysis revealed success rate for different techniques: laparoscopic (0.91, 95% CI 0.64 to 0.98), perineal (0.69, 95% CI 0.52 to 0.82), and transgluteal (0.50, 95% CI 0.37 to 0.63). The laparoscopic technique exhibited a complication rate of 16.0%. Meta-regression indicated that patient age and median follow-up significantly influenced outcomes.
CONCLUSION
While comparing surgical techniques is challenging, this meta-analysis highlights important outcome differences. The laparoscopic technique appears most promising for pain improvement. However, the study also emphasizes the need for further robust, long-term research due to significant heterogeneity across studies and prevelent risk of bias. PROSPERO database: CRD42023496564.

World Neurosurgery Nov 2023Abducens nerve (AN) schwannomas are extremely rare tumors. Clinical characteristics and factors that influence postoperative outcomes are not well defined. (Review)
Review
BACKGROUND
Abducens nerve (AN) schwannomas are extremely rare tumors. Clinical characteristics and factors that influence postoperative outcomes are not well defined.
OBJECTIVE
To characterize clinical features of AN schwannomas and predictors of surgical outcomes.
METHODS
PRISMA-guided systematic review of the literature on AN schwannomas was performed. Subsequently, univariate and multivariate regression analyses were performed to identify the predictive value of variables that influence postoperative outcomes.
RESULTS
A total of 42 studies with 55 patients were evaluated. The mean age at presentation was 43.9 ± 14.6 years. The most common presenting symptom was cranial nerve VI palsy (69.1%). Cavernous sinus (49.1%) and prepontine cistern (36.3%) were the most commonly involved locations. Complete recovery after surgery was seen in 36.3% at a median follow-up of 28.4 ± 25.8 months. Preoperative AN palsy (P < 0.001), suboccipital approach (P = 0.007), and subtotal resection of tumor (P = 0.044) were significant protective factors for postoperative complications. Prepontine location and postoperative complications were poor prognostic indicators of AN recovery (odds ratio [OR], 0.10, P = 0.030 and OR, 0.10, P = 0.028, respectively). Subtotal resection was significantly correlated with higher odds of AN recovery (OR, 6.06; P = 0.040).
CONCLUSIONS
AN schwannomas are rare but serious tumors that can cause significant morbidity, with only approximately one third of patients showing complete recovery after surgery. The suboccipital approach was a protective factor for postoperative complications, especially when combined with subtotal resection. Knowledge of these factors along with tumor characteristics helps optimize surgical planning and preoperative counseling.

Review
Pediatric basilar skull fractures (BSFs) are a rare type of traumatic head injury that can cause debilitating complications without prompt treatment. Here, we sought to review the literature and characterize the clinical features, management, and outcomes of pediatric BSFs. We identified 21 relevant studies, excluding reviews, meta-analyses, and non-English articles. The incidence of pediatric BSFs ranged from 0.0001% to 7.3%, with falls from multi-level heights and traffic accidents being the primary causes (9/21). The median presentation age ranged from 3.2 to 12.8 years, and the mean age of patients across all studies was 8.68 years. Up to 55% of pediatric BSFs presented with intracranial hematoma/hemorrhage, along with pneumocephalus and edema. Cranial nerve palsies were a common complication (9/21), with the facial nerve injured most frequently (7/21). While delayed cranial nerve palsy was reported in a few studies (4/21), most resolved within three months post-admission. Other complications included CSF leaks (10/21) and meningitis (4/21). Management included IV fluids, antiemetics, and surgery (8/21) to treat the fracture directly, address a CSF leak, or achieve cranial nerve compression. Despite their rarity, pediatric skull base fractures are associated with clinical complications, including CSF leaks and cranial nerve palsies. Given that some of these complications may be delayed, patient education is critical.

Meta-Analysis
BACKGROUND
Alpha-lipoic acid, epalrestat, and mecobalamin are widely used as monotherapies for diabetic peripheral neuropathy. However, whether a triple-combination therapy with these three drugs is superior to monotherapy or dual therapy remains debatable.
METHODS
Nine randomized controlled trials were identified through a search on electronic databases such as PubMed, Web of Science, and Cochrane Library. The trial participants (N = 1153) were divided into the experimental group who received the triple-combination therapy and the control group who received conventional or dual therapy with the aforementioned drugs.
RESULTS
Therapeutic outcomes were better in the experimental group than in the control group (odds ratio: 3.74; 95 % confidence interval: 2.57-5.45; I = 0 %; p < 0.00001). No statistic difference was noted in adverse effects. Compared with the control group, the experimental group exhibited significant improvements in median motor nerve conduction velocity (MNCV), sensory nerve conduction velocity (SNCV), peroneal MNCV, peroneal SNCV, and vibration perception thresholds (VPT) in the left and right lower limbs. In the control group, a subgroup analysis by treatment strategy revealed similar improvements in total efficacy, MNCV, and SNCV.
CONCLUSIONS
For diabetic peripheral neuropathy, the triple-combination therapy may be more effective than monotherapy or dual therapy.

PURPOSE
Morphological variations of the brachial artery are quite commonly discovered in routine dissection and have been the subject of many studies. However, there is a need for a clear classification. This work presents morphological variations of the brachial artery, based on numerous case reports and studies created for the appropriate classification and interpretation among surgeons and radiologists. It also discusses the most important clinical aspects of the given varieties.
METHODS
The research method is based on the combined interpretation of the researches based on numerous publications concerning both the principles of correctly classifying the described morphological variations of the brachial artery and the resulting clinical implications. This work considers atypical variations such as the presence of the superficial brachial artery, brachoradial artery, accessory brachial artery and absence of the brachial artery. Variations of the brachial artery in relation to the external and internal diameter of the vessel have also been discussed.
RESULTS
After conducting a complex analysis of the collected data, the fundamental principles for classifying such variability as superficial brachial artery, brachioradial artery and accessory brachial artery were defined. Additionally, clinical implications resulting from the above like the impact of the superficial brachial artery on the median nerve neuropathy and the positive correlation between the brachioradial artery and increased danger of incorrect transradial catheterization were demonstrated.
CONCLUSIONS
The clinical implications of the atypical arterial pattern within the upper limb are crucial during the angiography and surgical procedures so the variations affect the appropriate diagnosis and surgical intervention. Hence, the knowledge about the morphological variations of the brachial artery should be constantly broadened by radiologists and surgeons to improve the accuracy and effectiveness of the treatment process.

Review
BACKGROUND
The validity of the ULTT is unclear, due to heterogeneity of test procedures and variability in the definition of a positive test OBJECTIVE: To evaluate test procedures and positive diagnostic criteria for the upper limb tension test (ULTT) in diagnostic test accuracy studies.
METHODS
A systematic review of diagnostic accuracy studies was performed. We conducted a search of the DiTA (Diagnostic Test Accuracy) database and selected primary studies evaluating the diagnostic accuracy of the ULTT. We assessed risk of bias, performed data extraction on study characteristics, test procedures, and positive diagnostic criteria, and performed a descriptive analysis.
RESULTS
We included nine studies (681 participants), four diagnosing people with cervical radiculopathy (CR), four diagnosing people with carpal tunnel syndrome (CTS), and one included both CR and CTS. The risk of bias varied between 2 and 6 out of 6 positive items. Eight studies reported on the ULTT1 (median nerve). Overall, all studies clearly described their test procedures and positive diagnostic criteria although the order of movements and the diagnostic criteria between studies varied. We suggest a more standardised test procedure for the ULTT1 to consist of: 1) stabilising the shoulder in abduction, 2) extending the wrist/fingers, 3) supinating the forearm, 4) externally rotating the shoulder, 5) extending the elbow, and finally 6) performed structural differentiation by side bending (lateral flexion) of the neck. This proposed test procedure should reproduce the symptoms and enables the clinician to evaluate whether symptoms increase/decrease when stressing or relaxing the nerves.
CONCLUSION
Based on our findings we proposed a more standardised test procedure for the ULTT1 with accompanying positive diagnostic criteria to facilitate homogeneity in future diagnostic accuracy studies of the ULTT.

Review
Carpal tunnel syndrome (CTS) is a debilitating condition that can cause significant morbidity. Corticosteroid injection (CI) is a popular treatment for CTS. Short-term benefits of CI for CTS have been reported, but there is little evidence on long-term outcomes. We performed a systematic review in the PubMed/MEDLINE and Cochrane Library databases to identify studies which reported outcomes of CI for CTS with at least 1-year follow-up. We identified 20 total studies and extracted data on outcomes such as number of patients needing eventual surgery or reinjection, complications, and functional scores. In included studies, 41.6% of patients underwent eventual carpal tunnel release surgery (CTRS), 29% underwent reinjection, there were no major and approximately 34/1133 (3.0%) minor complications, and median/mean time from CI to eventual CTRS ranged from 128 to 446 days. There was disparity on the long-term efficacy of CI for functional outcomes. The evidence indicates that CI is a very low risk procedure that has potential to improve symptoms enough to either prevent or, in most cases, delay the need for further reintervention. However, our conclusions are limited by the heterogeneity of available studies. There is a need for further, high-quality research on this topic.
