The evolving role of MRI in the detection of extrathyroidal extension of papillary thyroid carcinoma: a systematic review and meta-analysis. BMC Cancer 2024; 24:1531. [PMID: 39696088 DOI: 10.1186/s12885-024-13288-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2024] [Accepted: 12/04/2024] [Indexed: 12/20/2024] Open
Abstract
BACKGROUND Papillary thyroid carcinoma (PTC) is the predominant form of thyroid cancer, and the presence of extrathyroidal extension (ETE) significantly impacts treatment decisions and prognosis. Accurate preoperative detection of ETE remains challenging, highlighting the need to evaluate advanced imaging techniques.This systematic review and meta-analysis aimed to investigate the diagnostic accuracy of magnetic resonance imaging (MRI) in detecting extrathyroidal extension (ETE) among patients diagnosed with papillary thyroid carcinoma (PTC). METHOD We conducted a comprehensive search of global databases including PubMed, Web of Science, EMBASE, and the Cochrane Library, spanning from inception to November 03, 2024. We included studies that utilized preoperative MRI to evaluate the presence of ETE. Quality assessment was carried out using the Joanna Briggs Institute (JBI) standard checklists. Data analysis was performed using Comprehensive Meta-Analysis (CMA) software version 3. The study protocol was registered in PROSPERO (CRD42024499536). RESULT Six studies were included in our final quantitative analysis. The included studies were classified into two groups; the first group focused on evaluating the accuracy of MRI in detecting ETE, while the second group assessed the apparent diffusion coefficient (ADC). The accuracy of MRI for overall ETE, minimal ETE (mETE), and gross ETE (gETE) was 81.0% (95% CI: 76.9%-85.6%), 72.9% (95% CI: 66.2%-78.6%), and 83.3% (95% CI: 75.2%-89.1%), respectively. MRI demonstrated a statistically significant difference in detecting gETE compared to mETE (OR = 1.85, 95% CI: 1.01-3.37, P-value = 0.045). Our analysis showed that the ADC of the lesion for b-value 500 is lower in patients with ETE compared to those without ETE (SMD = 0.95, 95% CI: 0.28-1.62, P-value = 0.005). CONCLUSION Our findings demonstrate that MRI has substantial accuracy in detecting ETE in PTC, especially for gross ETE. This suggests MRI could be a valuable tool in preoperative planning, helping to guide surgical decision-making by more precisely identifying patients at higher risk. However, the limited number of studies underscores the need for further research to confirm MRI's role in routine clinical practice and to refine imaging protocols for more accurate differentiation between minimal and gross ETE.

Efficacy of Radiofrequency Ablation in Autonomous Functioning Thyroid Nodules: A Comprehensive Systematic Review and Meta-analysis. Acad Radiol 2024; 31:4843-4855. [PMID: 39068094 DOI: 10.1016/j.acra.2024.06.023] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2024] [Revised: 06/15/2024] [Accepted: 06/17/2024] [Indexed: 07/30/2024]
Abstract
BACKGROUND Radiofrequency ablation (RFA) is a minimally invasive outpatient procedure that has recently emerged as a treatment option for autonomous functioning thyroid nodules (AFTNs), offering a less invasive alternative to surgery. The objective of this systematic review and meta-analysis is to evaluate the efficacy of RFA for AFTNs. METHOD Global databases of PubMed, Scopus, Embase, Web of Science, and Cochrane Library were systematically searched from 1990 until January 5, 2024, for studies on AFTNs undergoing RFA that presented volume reduction ratio (VRR) for at least one of 1, 3, 6 or 12 months post-operative follow-up with the results presented as means. The primary outcomes were VRR and TSH normalization rate, and the secondary outcomes were the cosmetic score, symptom score, and post-procedure complications. Heterogeneity was assessed by Cochrane and I2 statistics, and a random-effects model was used for meta-analysis. The study protocol was registered on PROSPERO (CRD42024499932). RESULTS A total of 10 eligible studies with a total sample size of 254 were included. The pooled VRR after 1, 3, 6, and 12 months of follow-up post-treatment with RFA was 46.6% (95% CI: 40.3-52.9%), 62% (95% CI: 57.6-66.4%), 67.4% (95% CI:62.3-72.6%), and 77.2% (95% CI: 79.2-81.5%), respectively. The overall rate of TSH normalization was 76.4% (95% CI: 58.1-88.4%). Based on included studies the overall rate of subclinical hypothyroidism as one of the most important side effects of this method was 4% (95% CI: 1.9%-8.1%). CONCLUSION RFA emerges as a promising non-surgical treatment for AFTNs, showing high rates of TSH normalization, tumor size reduction, and improved cosmetic and symptom scores. However, further research is needed to compare RFA with surgical methods and assess long-term outcomes.

Modulation of inflammatory markers in type 2 diabetes mellitus through gut microbiome-targeted interventions: An umbrella review on meta-analyses. Clin Nutr ESPEN 2024; 65:93-104. [PMID: 39551350 DOI: 10.1016/j.clnesp.2024.11.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/07/2024] [Revised: 09/23/2024] [Accepted: 11/05/2024] [Indexed: 11/19/2024]
Abstract
BACKGROUND & AIMS Type 2 diabetes mellitus (T2DM) poses a significant global health challenge due to various lifestyle factors contributing to its prevalence and associated complications. Chronic low-grade inflammation, characterized by elevated levels of inflammatory markers such as C-reactive protein (CRP), interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-α), plays a pivotal role in the pathogenesis of T2DM. Modulation of the gut microbiota through microbiome-targeted therapy (MTT), including probiotics, prebiotics, and synbiotics, has emerged as a potential strategy to mitigate inflammation and improve metabolic outcomes in T2DM. METHODS A systematic review and meta-analysis were conducted following PRISMA guidelines to evaluate the impact of MTT on inflammatory markers in patients with T2DM. Searches were performed in PubMed, Scopus, and Web of Science databases up to June 2024, with inclusion criteria limited to English-language meta-analyses of randomized controlled trials (RCTs) assessing the effects of probiotics, prebiotics, or synbiotics on inflammatory markers in T2DM patients. RESULTS Ten meta-analyses met the inclusion criteria, comprising studies investigating the effects of various MTT interventions on CRP, IL-6, and TNF-α levels in T2DM patients. Meta-analysis results indicated significant reductions in CRP (SMD: -0.070; 95 % CI: -0.119 to -0.020) and TNF-α (SMD: -0.370; 95 % CI: -0.554 to -0.186) levels following MTT, while IL-6 reductions (SMD: -0.070; 95 % CI: -0.269 to 0.129) did not reach statistical significance. However, heterogeneity in study quality, intervention protocols, and participant demographics posed challenges in interpretation. CONCLUSIONS While improvements in inflammatory markers with MTT have been observed, significant limitations-such as heterogeneity in study quality and variation in intervention protocols-highlight the need for further research to confirm its efficacy and clarify underlying mechanisms. Future studies should aim to address these limitations by exploring variations in dosage, supplement formulations, and bacterial strains, which are crucial for improving the reliability and broader applicability of MTT in the management of T2DM.

Cardiovascular and all-cause mortality outcomes of adrenalectomy versus medical treatment in primary aldosteronism: an umbrella review. Int J Surg 2024; 110:7367-7380. [PMID: 39248318 PMCID: PMC11573102 DOI: 10.1097/js9.0000000000002048] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2024] [Accepted: 08/11/2024] [Indexed: 09/10/2024]
Abstract
BACKGROUND Primary aldosteronism (PA) is now recognized as the most prevalent form of secondary hypertension globally, contributing significantly to cardiovascular morbidity and mortality. This umbrella review aims to systematically compare cardiovascular outcomes and all-cause mortality in PA patients undergoing adrenalectomy versus mineralocorticoid receptor antagonist (MRA) treatment, aiming to inform optimal management strategies. METHOD Following PRISMA guidelines (Supplemental Digital Content 1, http://links.lww.com/JS9/D386 ) (Supplemental Digital Content 2, http://links.lww.com/JS9/D387 ), a comprehensive search strategy was employed across multiple databases. Meta-analyses focusing on cardiovascular outcomes or all-cause mortality, comparing adrenalectomy and MRAs treatment in PA patients, were included. Studies were independently screened and assessed for quality using AMSTAR 2 (Supplemental Digital Content 3, http://links.lww.com/JS9/D388 ) and GRADE checklists. RESULTS A total of eight studies met the inclusion criteria. Adrenalectomy showed potential benefits over MRAs in reducing the risk of arrhythmias (OR=2.17; 95% CI: 1.25-3.76) and major adverse cardiovascular events (OR=1.81; 95% CI: 1.33-2.46). Patients treated with MRAs exhibited a higher risk of cardiovascular events (OR=1.23; 95% CI: 1.05-1.44), hypertension (OR=3.22; 95% CI: 1.15-8.97), and all-cause mortality (OR=3.03; 95% CI: 1.36-6.70) compared to adrenalectomy. CONCLUSION Adrenalectomy appears to offer favorable outcomes compared to MRAs treatment in PA patients, particularly in reducing the risk of major adverse cardiovascular events and all-cause mortality. These findings suggest the importance of considering surgical intervention as a primary treatment modality for PA.

Abstract
BACKGROUND Nonalcoholic fatty liver disease (NAFLD) is a global health challenge, with a rising rate in line with other metabolic diseases. We aimed to assess the global prevalence of NAFLD in adult and pediatric populations. METHODS PubMed, Scopus and Web of Science databases were systematically searched up to May 2023. Heterogeneity was assessed using Cochran's Q test and I2 statistics, and random-effects model was used for meta-analysis. Analyses were performed using STATA version 18. RESULTS A total of 479 studies with 78,001,755 participants from 38 countries were finally included. The global prevalence of NAFLD was estimated to be 30.2% (95% CI: 28.7-31.7%). Regionally, the prevalence of NAFLD was as follows: Asia 30.9% (95% CI: 29.2-32.6%), Australia 16.1% (95% CI: 9.0-24.8%), Europe 30.2% (95% CI: 25.6-35.0%), North America 29% (95% CI: 25.8-32.3%), and South America 34% (95% CI: 16.9-53.5%). Countries with a higher human development index (HDI) had significantly lower prevalence of NAFLD (coefficient = -0.523, p = 0.005). Globally, the prevalence of NAFLD in men and women was 36.6% (95% CI: 34.7-38.4%) and 25.5% (95% CI: 23.9-27.1%), respectively. The prevalence of NAFLD in adults, adults with obesity, children, and children with obesity was 30.2% (95% CI: 28.8-31.7%), 57.5% (95% CI: 43.6-70.9%), 14.3% (95% CI: 10.3-18.8%), and 38.0% (95% CI: 31.5-44.7%), respectively. CONCLUSION The prevalence of NAFLD is remarkably high, particularly in countries with lower HDI. This substantial prevalence in both adults and children underscores the need for disease management protocols to reduce the burden.

Abstract
PURPOSE Cerebral venous sinus thrombosis (CVST) is a potentially serious complication following surgical treatment of vestibular schwannoma, a benign tumor originating from Schwann cells of the vestibulocochlear nerve. This study aimed to determine the prevalence of CVST following surgical treatment of vestibular schwannoma and the factors contributing to its occurrence. METHOD Two independent researchers searched the global databases of PubMed, Web of Science, Scopus, and the Cochrane Library up to September 01, 2023. We employed a random-effects model for data analysis. Heterogeneity was evaluated using the I2 test. To assess the quality of the studies meeting our inclusion criteria, we employed the Joanna Briggs Institute Critical Appraisal Checklist. RESULTS We included 23 articles in this meta-analysis. The pooled prevalence of CVST after vestibular schwannoma surgery was 6.4% (95%CI 3.4-11.5%). The pooled prevalence of CVST following the retrosigmoid (RS), translabyrinthine (TL), and middle cranial fossa (MCF) approaches was 4.8% (95%CI 2.0-11.0%), 9.6% (95%CI 4.3-20.3%) and 9.9% (95%CI 1.6-42.2%), respectively, revealing a significant difference between the TL and the RS approaches (Odds ratio = 2.10, 95%CI 1.45-3.04, P < 0.001). The sigmoid sinus exhibited the highest post-operative thrombosis rate (7.9%), surpassing the transverse sinus (3.7%) and involvement of both sigmoid and transverse sinuses (1.6%), respectively. No significant associations were found with demographic or surgical factors. CONCLUSION In the current meta-analysis, we identified a 6.4% CVST prevalence following vestibular schwannoma surgery, with varying rates depending on the surgical approach. No significant associations with patient or surgical factors were found, emphasizing the need for heightened clinical vigilance and further research in this context.

Abstract
The growing prevalence of NAFLD and its global health burden have provoked considerable research on possible diagnostic and therapeutic options for NAFLD. Although various pathophysiological mechanisms and genetic factors have been identified to be associated with NAFLD, its treatment remains challenging. In recent years, exosomes have attracted widespread attention for their role in metabolic dysfunctions and their efficacy as pathological biomarkers. Exosomes have also shown tremendous potential in treating a variety of disorders. With increasing evidence supporting the significant role of exosomes in NAFLD pathogenesis, their theragnostic potential has become a point of interest in NAFLD. Expectedly, exosome-based treatment strategies have shown promise in the prevention and amelioration of NAFLD in preclinical studies. However, there are still serious challenges in preparing, standardizing, and applying exosome-based therapies as a routine clinical option that should be overcome. Due to the great potential of this novel theragnostic agent in NAFLD, further investigations on their safety, clinical efficacy, and application standardization are highly recommended.

Evaluating biomarkers for contrast-induced nephropathy following coronary interventions: an umbrella review on meta-analyses. Eur J Med Res 2024; 29:210. [PMID: 38561791 PMCID: PMC10983745 DOI: 10.1186/s40001-024-01782-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2024] [Accepted: 03/10/2024] [Indexed: 04/04/2024] Open
Abstract
BACKGROUND Contrast-induced nephropathy (CIN) is a form of acute kidney injury (AKI) occurring in patients undergoing cardiac catheterization, such as coronary angiography (CAG) or percutaneous coronary intervention (PCI). Although the conventional criterion for CIN detection involves a rise in creatinine levels within 72 h after contrast media injection, several limitations exist in this definition. Up to now, various meta-analyses have been undertaken to assess the accuracy of different biomarkers of CIN prediction. However, the existing body of research lacks a cohesive overview. To address this gap, a comprehensive umbrella review was necessary to consolidate and summarize the outcomes of prior meta-analyses. This umbrella study aimed to offer a current, evidence-based understanding of the prognostic value of biomarkers in predicting CIN. METHODS A systematic search of international databases, including PubMed, Scopus, and Web of Science, from inception to December 12, 2023, was conducted to identify meta-analyses assessing biomarkers for CIN prediction. Our own meta-analysis was performed by extracting data from the included studies. Sensitivity, specificity, positive likelihood ratio, and negative likelihood ratio were assessed using Meta-Disc and CMA softwares. RESULTS Twelve studies were ultimately included in the umbrella review. The results revealed that neutrophil gelatinase-associated lipocalin (NGAL) exhibited the highest area under the curve (AUC), followed by cystatin-C, urinary kidney injury molecule-1 (uKIM-1), and brain natriuretic peptide (BNP) with AUCs of 0.91, 0.89, 0.85, and 0.80, respectively. NGAL also demonstrated the highest positive likelihood ratio [effect size (ES): 6.02, 95% CI 3.86-9.40], followed by cystatin-C, uKIM-1, and BNP [ES: 4.35 (95% CI 2.85-6.65), 3.58 (95% CI 2.75-4.66), and 2.85 (95% CI 2.13-3.82), respectively]. uKIM-1 and cystatin-C had the lowest negative likelihood ratio, followed by NGAL and BNP [ES: 0.25 (95% CI 0.17-0.37), ES: 0.25 (95% CI 0.13-0.50), ES: 0.26 (95% CI 0.17-0.41), and ES: 0.39 (0.28-0.53) respectively]. NGAL emerged as the biomarker with the highest diagnostic odds ratio for CIN, followed by cystatin-C, uKIM-1, BNP, gamma-glutamyl transferase, hypoalbuminemia, contrast media volume to creatinine clearance ratio, preprocedural hyperglycemia, red cell distribution width (RDW), hyperuricemia, neutrophil-to-lymphocyte ratio, C-reactive protein (CRP), high-sensitivity CRP, and low hematocrit (P < 0.05). CONCLUSION NGAL demonstrated superior diagnostic performance, exhibiting the highest AUC, positive likelihood ratio, and diagnostic odds ratio among biomarkers for CIN, followed by cystatin-C, and uKIM-1. These findings underscore the potential clinical utility of NGAL, cystatin-C and uKIM-1 in predicting and assessing CIN.

Abstract
The third most frequent reason for hospitalized acute kidney injury is contrast-induced nephropathy (CIN). Percutaneous coronary intervention (PCI) and coronary angiography (CAG) are two interventions that can result in CIN. In this study, we sought to determine how well gamma-glutamyl transferase (GGT) can predict CIN following CAG and PCI. Method Two researchers searched through PubMed, Scopus, and Web of Science in November 2022 to find articles that examined GGT levels in CIN patients following PCI or CAG. To rate the quality of the studies, the Joanna Briggs Institute Critical Appraisal Checklist was employed. The Cochran test and I2 statistics were utilized to assess study heterogeneity. To calculate the number of participants required to reject the null hypothesis, power analysis was used. We evaluated the epidemiologic strength of the results using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE). The authors used Comprehensive Meta-analysis Version 3 to summarize the results. Results GGT was shown to be considerably greater in patients with CIN according to the meta-analysis's findings (odds ratio: 3.21, 95% CI: 1.26-8.15, P=0.014); nevertheless, the findings were accompanied by significant heterogeneity (I2=91.93%, P<0.001). Although the relationship between CIN and GGT was power full regarding power analysis (1- β =1, number of effect sizes=4, the average number per group=336), very low quality of evidence was observed regarding GRADE criteria. Conclusions These results suggest the GGT level may be a predictor of contrast-induced nephropathy in patients having cardiac catheterization; however, more research is required to prove the epidemiological validity.

Abstract
Background Smoking poses a significant risk for colorectal cancer (CRC), considered the third leading reason for cancer-related deaths worldwide. However, there has been limited research on the relationship between smoking and CRC in the Eastern Mediterranean Regional Office (EMRO). Therefore, a meta-analysis was conducted to combine available data and gain a comprehensive understanding of the relationship between smoking and CRC in EMRO. Methods Two independent researchers searched PubMed, Scopus, and Web of Science until December 2022. The included studies were checked for risk of bias administering the Newcastle-Ottawa scale. Heterogeneity was evaluated using I2 statistics and the Cochrane test. Publication bias was determined through funnel plot analysis and Egger's regression test. Additionally, a meta-regression analysis explored the impact of a country's Human Development Index (HDI) on the relationship between smoking and CRC. Results The final analysis included 26 studies, revealing a significant association between smoking and CRC (OR = 1.40; 95% CI: 1.11 - 1.78; P = 0.004). Moreover, smoking had a more pronounced adverse effect on CRC in countries with higher HDIs compared to those with lower HDIs (OR = 1.30; 95% CI: 0.99 - 1.71; P = 0.054). Conclusions Our findings underscore the importance of implementing smoking cessation programs and policies in EMRO countries, as they demonstrate a positive relationship between smoking and the risk of CRC. Furthermore, the results suggest that a country's level of human development may influence the association between smoking and CRC. Further research is needed to investigate this potential connection and develop targeted public health interventions.

Abstract
Hypoxia, a primary stimulus for angiogenesis, is important for tumour proliferation and survival. The effects of hypoxia on parathyroid tumour cells, which may also be important for parathyroid autotransplantation in patients, are, however, unknown. We, therefore, assessed the effects of hypoxia on gene expression in parathyroid adenoma (PA) cells from patients with primary hyperparathyroidism. Cell suspensions from human PAs were cultured under normoxic or hypoxic conditions and then subjected to cDNA expression analysis. In total, 549 genes were significantly upregulated and 873 significantly downregulated. The most highly upregulated genes (carbonic anhydrase 9 (CA9), Solute carrier family 2A1 (SLC2A1) and hypoxia-inducible lipid droplet-associated protein (HIG2)) had known involvement in hypoxia responses. Dysregulation of oxidative phosphorylation and glycolysis pathway genes were also observed, consistent with data indicating that cells shift metabolic strategy of ATP production in hypoxic conditions and that tumour cells predominantly utilise anaerobic glycolysis for energy production. Proliferation- and angiogenesis-associated genes linked with growth factor signalling, such as mitogen-activated protein kinase kinase 1 (MAP2K1), Jun proto-oncogene (JUN) and ETS proto-oncogene 1 (ETS1), were increased, however, Ras association domain family member 1 (RASSF1), an inhibitor of proliferation was also upregulated, indicating these pathways are unlikely to be biased towards proliferation. Overall, there appeared to be a shift in growth factor signalling pathways from Jak-Stat and Ras signaling to extracellular signal-regulated kinases (ERKs) and hypoxia-inducible factor (HIF)-1α signalling. Thus, our data demonstrate that PAs, under hypoxic conditions, promote the expression of genes known to stimulate angiogenesis, as well as undergoing a metabolic switch.

Abstract
Abstract
Background
Several studies have compared outcomes after elective open and endovascular approaches to abdominal aortic aneurysm (AAA) surgery, with varying results.
Methods
A random-effects meta-analysis was undertaken to compare operative outcomes, postoperative complications, 30-day mortality and long-term patient survival after surgery. Endpoints were compared using odds ratios (ORs), weighted mean differences (WMDs) or log hazard ratios (HRs) as appropriate.
Results
Forty-two studies comprising 21 178 patients (10 855 open; 10 323 endovascular) were included. In the elective setting (20 715 patients), the endovascular method was associated with a shorter stay in intensive care (WMD − 36 h; P < 0·001) and a shorter total postoperative stay (WMD − 5·4 days; P < 0·001). Cardiac (OR 1·76; P = 0·002) and respiratory (OR 4·01; P < 0·001) complications were more common after open surgery. In the endovascular group, 30-day mortality was lower (OR 0·46; P < 0·001). Endovascular surgery was also associated with an improved long-term aneurysm-related mortality (HR 0·39; P < 0·001). For ruptured AAA (463 patients), the less invasive operation was associated with a reduced stay in intensive care (WMD − 100·4 h; P = 0·005) and a significantly lower 30-day mortality (OR 0·45; P = 0·005).
Conclusions
The endovascular repair of AAA offers a clear benefit in terms of reduction in postoperative adverse events and 30-day mortality. In the longer term, it is also associated with a reduction in aneurysm-related mortality, but not in all-cause mortality.

Abstract
Sorption of Ni2+ ions by AlPO4 is studied as a function of concentrations and temperature at pH 7. Potentiometric titration, dissolution and FTIR studies are employed to determine the mechanism of the process of the uptake of Ni2+ ions which is found to be both the ion exchange and the surface precipitation of the corresponding metal phosphates. Freundlich equation is found applicable to the sorption data, and is employed to evaluate the thermodynamic parameters deltaH(o) and deltatS(o).

Abstract
Sorption studies were conducted for Co2+ ions on AlPO4 at different concentrations and temperatures. Sorption of Co2+ was found to increase with increase in concentration and temperature. To determine the mechanism of the sorption process, dissolution of AlPO4 in the presence of Co2+ ions and desorption studies were performed which indicated the mechanism of sorption to be the ion exchange followed by precipitation. FTIR studies were also employed to confirm the proposed mechanism.

Abstract
1. The activation of climbing fibres projecting to the posterior lobe cerebellar cortex by focal stimulation of the cerebral corticofugal pathway was investigated in anaesthetised rats. Large climbing fibre responses were evoked in parts of crus II and paramedian lobule by stimulation of corticofugal fibres. Lesions of the pyramidal tract just rostral to the inferior olive substantially reduced these responses, suggesting that they were not mediated by relays in the rostral brainstem. 2. By comparison of latencies of climbing fibre responses evoked from different locations in the corticofugal pathway, the conduction velocities of the corticofugal fibres that mediate the responses were estimated to be 1.9 +/- 0.3 m s(-1) (mean +/- S.E.M.). The fastest conducting corticofugal fibres were estimated to conduct significantly faster (18.7 +/- 2.3 m s(-1)). 3. Climbing fibre responses with similar form and cerebellar distribution were evoked from sites in the pyramidal tract rostral and caudal to the inferior olive. This suggests that at least a proportion of the fibres that activate climbing fibres are corticospinal fibres. 4. Lesions of the dorsal column nuclei did not affect the climbing fibre responses evoked in crus II, and produced a relatively small reduction of the responses in the paramedian lobule. This implies that the climbing fibre responses were not exclusively mediated via the dorsal column nuclei. 5. Corticofugal evoked climbing fibre responses were mapped across the cerebellar hemisphere. At some sites they were co-localised with responses evoked by limb afferents. On the basis of limb afferent inputs and other work, these zones were tentatively identified as being functionally equivalent to the c1, c2 and d zones described in the cat.

Abstract
Eighteen patients with hip abductor paralysis owing to poliomyelitis underwent external oblique muscle transfer. Five male and 13 female patients with a mean age of 15 years 5 months (range, 10-23 years) with an average follow-up of 5 years (range, 2-11 years) were studied. An improvement in gait with decreased limp and swaying and increased ability to walk long distances was seen in 17 patients. Nine patients became free of their assistive ambulatory devices. Subjective improvement was observed in 16 patients (the improved appearance being the main element of satisfaction). According to a detailed scoring system, six excellent, six good, three fair, and three poor results were identified. There was very good correlation between the scoring system and the final outcome, making it a valuable predictive point system. The transfer was suitable for flail lower limb as well.

Abstract
Tibial hemimelia often produces major limb length problems (1,6,9,15) as well as foot deformity. The decision to perform reconstructive surgery depends on the expected leg-length discrepancy, the anomalies of the foot, and the status of the knee (4,6,8,15). Congenital bone deficiencies usually have a constant rate of growth inhibition (8), and leg lengthening is often associated with more complications (5,13). The complication rate is also increased with the increased leg-length discrepancy (5). In tibial hemimelia with functioning quadriceps (types I and II) and a functional foot, centralization of the fibula onto the talus and synostosis with the proximal tibia is an accepted reconstructive procedure (1,4,6,7,9,15). However, when the transplanted fibula produces a functional limb for the patient, the correction of leg-length inequality would be a challenge. This is a report of such a case.

Abstract
Fifteen cases of paralysis of the quadriceps muscles secondary to poliomyelitis were managed by hamstring tendon transfers with an average follow-up of 48 months. Results of 13.5% excellent, 73% good, and 13.5% fair were obtained, according to an objective scoring system. Significant improvement in gait pattern, relief from brace use, or "hand-on-thigh" ambulation was seen in all cases. A mean extension lag of 30 degrees was observed in patients examined in the sitting position. Lack of active terminal knee flexion, prohibiting comfortable floor sitting, was the main untoward effect and the source of complaint in four patients.
