简介：客观：在食管的恶意的阻塞上学习内视镜的治疗的效果。方法：先进食道的癌症病人的64个盒子有食管的阻塞，7个盒子不能被操作，57个盒子复发了在操作以后的损害和放射治疗。阻塞都与食道的扩张器被扩大，然后用elemene乳剂注射和stent的本地化疗，或本地管理被对待被放在食道的腔。结果：阻塞与膨胀被减轻仅仅大约一个星期，而是阻塞，用用另外的治疗在膨胀以后减轻了超过三个月。在膨胀以后，然而，癌的PR在本地化疗组是大约80%CR是大约8%，PR在elemene的组是大约92%乳剂注射。结论：内视镜的治疗是为先进食道的癌症的一个有效辩解的方法。

简介：AbstractHypertrophic cardiomyopathy (HCM), the most common single-gene cardiovascular disease, is associated with increased risk for arrhythmias, heart failure, and sudden cardiac death. The hemodynamic changes known to occur during pregnancy can exacerbate heart failure and arrhythmias in women with HCM. We present a 30-year-old woman with HCM to illustrate the benefits of multidisciplinary team management of severe left ventricular outflow tract obstruction (peak gradient >100 mmHg) for optimal maternal and fetal outcomes.

简介：AbstractIntroduction:Congenital nasal pyriform aperture stenosis (CNPAS) is a rare congenital condition of structural nasal obstruction. Respiratory distress, stertor, and poor feeding are often presenting features.Case Presentation:We report a case of a newborn diagnosed with CNPAS at 3 weeks of life. The diagnosis was missed on a nasoendoscopy at day 3 of life but was realised following a facial CT when the infant presented with ongoing symptoms of upper airway obstruction. Nasal dilation was performed successfully.Conclusion:CNPAS should be considered in any neonate with upper airway obstruction. A normal nasoendoscopy does not exclude the diagnosis.

简介：AbstractObjective:To compare and correlate the efficacy of the NOSE score & the VAS score in determining the symptomatic benefit in patients undergoing septoplasty.Materials and methods:Eighty patients with deviated nasal septum undergoing septoplasty were included in the study. NOSE score & VAS score (out of 100) was documented before and after surgery. Results were correlated and compared statistically.Results:In the NOSE score, the most bothersome symptom was trouble breathing through the nose (85.83); followed by Nasal obstruction or blockage (82.50). Wilcoxon test showed significant improvement with NOSE score and VAS score in all patients at 1 month and 3 months. Spearman’s coefficient showed a positive correlation between the two, though the score improvement and patient satisfaction rate was significantly high with NOSE score.Conclusions:NOSE score and the VAS score both provide effective framework for evaluating treatment responses after septoplasty. However, the NOSE score showed higher improvement and better patient satisfaction rate when used to measure of nasal obstruction as compared to the VAS score.
