ABSTRACT A previous study has reported the therapeutic effects of interlaminar/transforaminal approaches under full-endoscopic visualization to treat L5-S1 lumber disc herniation (LDH). However, the comparison of interlaminar/transforaminal approaches to treat other segments of LDH remains unclear. Objective: To evaluate the clinical efficacy of full-endoscopic interlaminar and transforaminal lumbar discectomy to treat LDH. Methods: A total of 93 patients with LDH who underwent fully-endoscopic lumbar interlaminar/transforaminal discectomy were retrospectively collected. Patients were divided into a Transforaminal group (n=41) and an Interlaminar group (n=52). Clinical efficacy was evaluated by visual analogue scale (VAS), the Oswestry disability index (ODI), and the modified MacNab scoring system. Results: Of the 93 patients, involving segments in LDH referred to L3-4, L4-5, and L5-S1. The fluoroscopy times in the Interlaminar group were smaller than that of the Transforaminal group. We found no obvious significances between the Transforaminal and Interlaminar groups regarding operation time, incision length, postoperative landing time, hospitalization, and incision healing time. Postoperative VAS and ODI scores notably improved at follow-up. Besides, almost 90% LDH patients achieved excellent/good outcomes. Conclusion: The full-endoscopic visualization technique via interlaminar and transforaminal approaches safely and effectively treat LDH. Level of Evidence III, Retrospective Study.
RESUMO Um estudo anterior relatou os efeitos terapêuticos das abordagens interlaminar/transforaminal sob visualização totalmente endoscópica para tratar a hérnia de disco lombar (HDL) L5-S1. No entanto, a comparação das abordagens interlaminar/transforaminal para o tratamento de outros segmentos de HDL permanece pouco clara. Objetivo: Avaliar a eficácia clínica da discectomia lombar interlaminar e transforaminal totalmente endoscópica no tratamento da HDL. Métodos: Foram recolhidos retrospetivamente 93 pacientes com HDL submetidos a discectomia lombar interlaminar/transforaminal totalmente endoscópica. Os pacientes foram divididos em um grupo transforaminal (n=41) e um grupo interlaminar (n=52). A eficácia clínica foi avaliada através da escala visual analógica (EVA), do índice Oswestry de incapacidade (ODI) e do sistema de pontuação de MacNab modificado. Resultados: Dos 93 pacientes, os segmentos envolvidos na HDL referiam-se a L3-4, L4-5 e L5-S1. Os tempos de fluoroscopia no grupo Interlaminar foram menores do que no grupo Transforaminal. Não encontramos significâncias óbvias entre os grupos Transforaminal e Interlaminar em relação ao tempo de operação, comprimento da incisão, tempo de pós-operatório, hospitalização e tempo de cicatrização da incisão. As pontuações EVA e ODI pós-operatórias melhoraram notavelmente no acompanhamento. Além disso, quase 90% dos pacientes com HDL obtiveram resultados excelentes/bons. Conclusão: A técnica de visualização totalmente endoscópica através de abordagens interlaminar e transforaminal trata a HDL de forma segura e eficaz. Nível de Evidência III, Estudo Retrospectivo.

Objective@#To compare and correlate the findings of intravoxel incoherent motion (IVIM) magnetic resonance (MR) imaging and arterial spin labeling (ASL) imaging in characterizing parotid gland tumors. @*Materials and Methods@#We retrospectively reviewed 56 patients with parotid gland tumors evaluated by MR imaging. The true diffusion coefficient (D), pseudo-diffusion coefficient (D*), and fraction of perfusion (f) values of IVIM imaging and tumor-to-parotid gland signal intensity ratio (SIR) on ASL imaging were calculated. Spearman rank correlation coefficient, chi-squared, Mann-Whitney U, and Kruskal-Wallis tests with the post-hoc Dunn-Bonferroni method and receiver operating characteristic curve assessments were used for statistical analysis. @*Results@#Malignant parotid gland tumors showed significantly lower D than benign tumors (p = 0.019). Within subgroup analyses, pleomorphic adenomas (PAs) showed significantly higher D than malignant tumors (MTs) and Warthin’s tumors (WTs) (p < 0.001). The D* of WTs was significantly higher than that of PAs (p = 0.031). The f and SIR on ASL imaging of WTs were significantly higher than those of MTs and PAs (p < 0.05). Significantly positive correlation was found between SIR on ASL imaging and f (r = 0.446, p = 0.001). In comparison with f, SIR on ASL imaging showed a higher area under curve (0.853 vs. 0.891) in discriminating MTs from WTs, although the difference was not significant (p = 0.720). @*Conclusion@#IVIM and ASL imaging could help differentiate parotid gland tumors. SIR on ASL imaging showed a significantly positive correlation with f. ASL imaging might hold potential to improve the ability to discriminate MTs from WTs.
Résumé
There are many medications available to treat spasticity, but the tolerability of medications is the main issue for choosing the best treatment. The objectives of this study were to compare the efficacy and adverse effects of tolperisone compared to baclofen among patients with spasticity associated with spinal cord injury. Patients received baclofen plus physical therapy (BAF+PT, n=135) or tolperisone plus physical therapy (TOL+PT, n=116), or physical therapy alone (PT, n=180). The modified Ashworth scale score, the modified Medical Research Council score, the Barthel Index score, and the Disability Assessment scale score were improved (P<0.05 for all) in all the patients at the end of 6 weeks compared to before interventions. After 6 weeks, the overall coefficient of efficacy of the intervention(s) in the BAF+PT, TOL+PT, and PT groups were 1.15, 0.45, and 0.05, respectively. The patients of the BAF+PT group reported asthenia, drowsiness, and sleepiness and those of the TOL+PT group reported dyspepsia and epigastric pain as adverse effects. When comparing drug interventions to physical therapy alone, both baclofen plus physical therapy and tolperisone plus physical therapy played a significant role in the improvement of daily activities of patients. Nonetheless, baclofen plus physical therapy was tentatively effective. Tolperisone plus physical therapy was slightly effective. In addition, baclofen caused adverse effects related to the sedative manifestation (Level of Evidence: III; Technical Efficacy Stage: 4).

Objective:To explore the clinicopathologic characteristics of gastric mixed adenoneuroendocrine carcinoma (MANEC). Methods:From January 2011 to December 2016, the clinical and pathological data of 35 patients with gastric MANEC who were diagnosed and surgically treated in Tianjin Medical University Cancer Institute and Hospital were analyzed retrospectively. Results:The average age of the 32 men and 3 women in this study was 61.6±7.5 years. Tumor locations were as follows:17 related to gastric cardia, 9 related to gastric body, 8 related to gastric antrum, and 1 related to gastric stump. Clinical symptoms were non-specific and the diagnosis relies on post-operative pathological examination. Using the histological microscope, the affected structures were detected in neuroendocrine systems and tissue linings. Immunohistochemical staining showed that carcinoembryonic antigen (CEA) and cytokeratins 8 and 18 (CK8/18) were expressed in 32 and 33 adenocarcinoma-related cases, respectively, whereas synaptophysin (Syn) and chromogranin A (CgA) were revealed in 33 and 27 neuroendocrine-related cases, respectively. Al patients received surgical resection. A total of 17 incidents of death were reported at three years after the operation, and most of the patients were at clinical stageⅢorⅣ. Conclusion:Gastric MANEC is a rare neoplasm and is often diagnosed at its advanced stage and mainly occurs in the aged population. Neuroendocrine structures and glandular tissues are the most frequent location of such condition. Diagnosis relies on both immunohistochemical and histological examinations. Surgical resection is the most effective treatment, but the prognosis of this condition remains poor.
