Growth of the Social #RadOnc Network on Twitter

PurposeTwitter is an increasingly popular social media platform within the health care community. The objective of this analysis is to characterize the profile of radiation oncology–related tweets and Twitter users over the past 6 years.Methods and MaterialsUsing the web-based social media analytics platform Symplur Signals, we filtered tweets containing at least 1 of the following hashtags or key words: #radonc, #radiationoncology, "rad onc," or "radiation oncology." We evaluated radiation oncology–related Twitter activity between October 2014 and March 2020 for tweet frequency, tweet content, and individuals or groups posting tweets. We identified the most influential Twitter users contributing to radiation oncology–related tweets.ResultsFrom 2014 to 2020, the quarterly volume of radiation oncology–related tweets increased from 5027 to 29,763. Physicians contributed the largest growth in tweet volume. Academic radiation oncologists comprise 60% of the most influential Twitter accounts responsible for radiation oncology–related content. The number of radiation-oncology resident physicians on Twitter increased from 25 to 328 over the past 6 years, and 20% of radiation-oncology residency programs have a Twitter account. Seventy-one percent of radiation oncology–related tweets generated direct communication via mentions, and 59% of tweets contain links to external sources, including scientific articles.ConclusionsThe number of physicians contributing radiation oncology–related Twitter content has increased significantly in recent years. Academic radiation oncologists are the primary influencers of radiation oncology–related Twitter activity. Twitter is used by radiation oncologists to both professionally network and discuss findings related to the field. There remains the opportunity for radiation oncologists to broaden their audience on Twitter to encompass a more diverse community, including patients.     

宫腹腔镜联合手术诊治不孕症150例分析

目的:探讨宫腹腔镜联合手术在诊治不孕症中的应用。方法:对150例不孕症患者行宫腹腔镜联合手术,对不孕症病因进行诊断,同时行治疗。结果:盆腔粘连和输卵管阻塞是不孕症的主要原因。子宫内膜息肉和正常盆腔占次要比例。子宫内膜异位症和多囊卵巢也是主要病因。150例同时行宫腹腔镜输卵管通液和各种疾病的治疗。联合手术后妊娠率为48.8%。结论:腹腔镜联合手术,在一次麻醉下,可以对不孕的原因全面评价和明确诊断,在诊断同时进行治疗,对不孕症的诊断和治疗有重大的意义,值得推广。     

Acute respiratory distress during Caesarean section under spinal anaesthesia A probable case of anaphylactoid reaction to Syntocinon

A case of life-threatening respiratory distress during a Caesarean section under spinal anaesthesia is reported. Possible causes of the event including anaphylactoid reactions and the methods of their diagnosis are discussed. The most likely cause of the episode was felt to be an anaphylactoid reaction to Syntocinon.     

The Rigiflex TTS: A New Method to Dilate Benign Esophageal Stenosis

Abstract: This paper dicusses the use of esophageal dilatation with a Rigiflex TTS balloon. This method was used 45 times on 11 patients affected by anastomotic or a severe grade peptic esophageal stenosis. Fluoroscopic guidance was used in 36 procedures (80%) without effecting the mean duration of the treatment (12 minutes). The results were considered satisfactory when these goals had been achieved: a) dilatation of the stenosis over 15 mm; b) a dysphagia free-time of more than 6 months. A satisfactory result was achieved in 10 patients (90.9%), without deaths and major complications. 5 patients received 1 dilatation and the other 5 needed, 3-3-4-7–11 procedures respectively to obtain a satisfactory result. On these basis we consider that its great efficacy, security and tolerability depend on the following characteristics of the Rigiflex TTS balloon: 1) “radial” dilatation; 2) the possibility of introducing the balloon through the operative channel of the fiberscope; 3) direct visualization of the stenosis during dilatation. The following disadvantages with this method are: the absence of a tactile sensation of dilatation and the elevated cost of the instrument. We conclude that the Rigiflex TTS balloon is an important alternative to guide-wire techniques, especially for the treatment of severe esophageal strictures.     

妊娠肝内胆汁淤积症患者血清一氧化氮和内皮素的变化及意义

目的：探讨妊娠肝内胆汁淤积症（ICP）患者外周静脉血清、新生儿脐静脉血清中一氧化氮（NO）、内皮素（ET）、丙二醛（MDA）和超氧化物歧化酶（SOD）含量的变化及在ICP发病中的作用。方法：以ICP组28例为研究组，测定其外周静脉血清及新生儿脐静脉血清中的NO、ET、MDA和SOD，以年龄相近的24例正常孕妇作为对照组。结果：ICP患者的MDA和ET含量较正常晚期妊娠显著增高（P＜0．01），ICP患者的NO和SOD含量与对照组相比无显著性差异（P＞0．05）。母血清中NO、ET、MDA含量均较新生儿脐静脉血清中的含量高，差异有显著性（P＜0．01）。结论：妊娠期体内氧化和抗氧化失衡及ET水平的增高可能与ICP的发生、发展有关。

Hazards of smoking

A strong association exists between cigarette smoking and several diseases namely, cancer of the lung, bronchitis and emphysema, cancer of the larynx, oral cavity and oesophagus, gastric and duodenal ulcers, Crohn's disease, cancer of the bladder, coronary artery disease, macrocytosis, polycythaemia, leukaemia, etc. This is due to the harmful constituents of cigarette and other modalities smoking. Smokers not only harm themselves but also harm those around. Foetal malformations, abortions, stillbirths, prematurity and low birth weight are common in smoker mothers. These are the effects of passive smoking. There is no safer cigarette in the market even by lowering its harmful constituents. Mass education about the hazards of smoking with emphasis on complete stoppage of smoking is the only way to prevent its rising incidence.
