xlomafota13 shared this article with you from Inoreader Message: 本文分析1例Smith-Magenis综合征患儿在耳鼻咽喉方面的临床特点。患儿，女，9岁，因"反复咽痛约1个月"就诊于吉林大学第二医院。平日睡眠周期短，动作多，说话声音嘶哑。体检见身体多个部位发育异常包括独特的面部特征如方脸、眼睛深陷、下颚偏大、鼻梁塌陷、唇外翻、下颌前突，短指/趾畸形，身材矮小，睡眠障碍，刻板行为发育迟缓、智力低下，语言能力发育迟滞及隐性脊柱裂。常规染色体核型为46，XX，高分辨染色体核型分析17号染色体短臂p11.2存在大小约3.5M缺失，分子核型为46，XX，arr17p11.2（16705818-20178312）*1。因其发病率低，在耳鼻咽喉方面极少报道，本文通过对所收治的1例SMS患儿的全身特点及耳鼻咽喉方面的特征进行分析，以期提高对该病的认知。. This article analyzes the clinical characteristics of otolaryngology in a child with Smith-Magenis syndrome. The patient, female, 9 years old, was admitted to the Second Hospital of Jilin University because of "repeated sore throat for about 1 month". On weekdays, the sleep cycle is short, there are many movements, and the voice is hoarse. Physical examination revealed developmental abnormalities in multiple parts of the body including distinctive facial features such as square face, sunken eyes, enlarged jaw, collapsed nasal bridge, lip eversion, mandibular protrusion, brachydactyly, short stature, sleep disturbance, stereotyped behavior Developmental delay, mental retardation, language retardation and spina bifida. The conventional karyotype is 46, XX. The high-resolution karyotype analysis shows that there is a deletion of about 3.5M in the short arm p11.2 of chromosome 17. The molecular karyotype is 46, XX, arr17p11.2 (16705818-20178312)*1. Due to its low incidence, it is rarely reported in the field of ENT. This article analyzes the systemic and ENT characteristics of a patient with SMS in order to improve the awareness of the disease. .

Effects of mesenchymal stem cells on primary culture and secretion function of parathyroid cells in vitro

xlomafota13 shared this article with you from Inoreader Effects of mesenchymal stem cells on primary culture and secretion function of parathyroid cells in vitro Via Zhonghua Er Bi Yan Hou Tou Jing Wai Ke Za Zhi Zhonghua Er Bi Yan Hou Tou Jing Wai Ke Za Zhi. 2022 Feb 7;57(2):185-190. doi: 10.3760/cma.j.cn115330-20210331-00165. ABSTRACT Objective: To investigate the effects of adipose-derived mesenchymal stem cells (ADMSCs) on proliferation and hormone secretion of parathyroid cells in votro. Methods: The parathyroid cells and ADMSCs were obtained from 10 SD rats by cell separation and culture. The phenotype of P3 generation for ADMSCs was detected by flow cytometry. The co-culture of parathyroid cells and ADMSCs was conducted in the ratios of 2∶1, 1∶1, 1∶2 and 1∶5, respectively. The level of parathyroid hormone in cell supernatant was determined. The results were compared with the parathyroid hormone in the supernatant of parathyroid cells cultured separately in the corresponding number. The effects of ADMSCs on the hormone secretion of parathyroid cells were evaluated. SPSS 11.0 software was used for statistical analysis . Results: The primary culture of either parathyroid cells or ADMSCs and the co-culture of these cells in vitro were performed successfully, and the in vitro culture of different proportions of the two cells showed different effects on parathyroid hormone secretion. The co-culture of parathyroid cells and ADMSCs, especially in the ratio of 1∶5, facilitated the secretion of parathyroid hormone ((1.3±0.0) vs. (0.8±0.1), (1.3±0.0) vs. (0.9±0.0), (1.7±0.5) vs. (0.9±0.0), (1.7±0.0) vs. (1.2±0.2))ng/L with t value of 25.46, 64.30, 3.32, 7.16, P<0.05 on the 2nd, 4th, 6th and 8th days respectively. Secondly, when the ratio was 1∶2, the PTH level showed an upward trend. Conclusion: Parathyroid cells and ADMSCs can be co-cultured in vitro, facilitating the secretion of parathyroid hormone under the appropriate cell proportion such as the ratio of by parathyroid cells to ADMSCs at 1∶5.

Visual Servoing of Continuum Robots: Methods, Challenges, and Prospects

xlomafota13 shared this article with you from Inoreader Visual Servoing of Continuum Robots: Methods, Challenges, and Prospects Via The International Journal of Medical Robotics and Computer Assisted Surgery Abstract Recent advancements in continuum robotics have accentuated developing efficient and stable controllers to handle shape deformation and compliance. The control of continuum robots using physical sensors attached to the robot, particularly in confined spaces, is difficult due to their limited accuracy in three-dimensional deflections and challenging localization. Therefore, using non-contact imaging sensors finds noticeable importance, particularly in medical scenarios. Accordingly, given the need for direct control of the robot tip and notable uncertainties in kinematics and dynamics of continuum robots, many papers have focused on the visual servoing of continuum robots in recent years. The significance of this research toward safe human-robot interaction has fueled our survey on the previous methods, current challenges, and future opportunities. Beginning with actuation modalities and modeling approaches, the paper investigates visual servoing methods in medical and non-medical s cenarios. Finally, challenges and prospects of visual servoing for continuum robots are discussed, followed by concluding remarks. This article is protected by copyright. All rights reserved.

Airway management in patients with lingual thyroid: a case report and review of the literature

xlomafota13 shared this article with you from Inoreader Airway management in patients with lingual thyroid: a case report and review of the literature Via http://link.springer.com/journal/405,European archives of oto-rhino-laryngology,The European Federation of Oto-Rhino-Laryngological Societies (EUFOS) : affiliated with the German Society for Oto-Rhino Eur Arch Otorhinolaryngol. 2022 Feb 24. doi: 10.1007/s00405-022-07310-0. Online ahead of print. ABSTRACT PURPOSE: To review the management of patients with lingual thyroid (LT) causing upper airway obstruction and to suggest a diagnostic and therapeutic workflow. METHODS: A PubMed review of published cases from January 1980 up to December 2020 of LT causing upper airway obstruction. We selected cases of confirmed LTs that presented with non-state-dependent airway obstruction. An illustrative case report is presented. RESULTS: Twenty-one articles fulfilling the inclusion criteria were found, reporting 24 cases (7 neonatal, 2 pediatric and 15 adults). The main presenting symptoms was dyspnea with increased work of breathing, followed by dysphagia and stridor most commonly in neonates. At least one imaging modality was performed in all patients. Thyroid function was altered in half the patients and normal in the other half. Th e LT was the only thyroid tissue in all cases except 2. Altogether, 5/24 patients required tracheostomies and two-thirds of the patients underwent surgical resection of the LT (mostly transoral). Also 2/3 of the patients received thyroid replacement therapy. After a median follow-up of 17 months, airway symptoms had fully resolved for all patients but one. CONCLUSION: While rare, ectopic LTs should be considered in the differential diagnosis of stridor, dyspnea and airway obstruction. In neonates, concomitant presence of hypothyroidism on neonatal screening and airway obstruction should prompt the search for a LT. Early identification and thyroid replacement therapy seem to significantly relieve symptoms of upper airway obstruction, but severe obstruction and concomitant airway lesions may require more definitive management approaches.
