Manejo y seguimiento radiológico del paciente post-COVID-19

Most of the patients who overcome the SARS-CoV-2 infection do not present complications and do not require a specific follow-up, but a significant proportion (especially those with moderate / severe clinical forms of the disease) require clinicalradiological follow-up. Although there are hardly any references or clinical guidelines regarding the long-term follow-up of post-COVID-19 patients, radiological exams are being performed and monographic surveillance consultations are being set up in most of the hospitals to meet their needs. The purpose of this work is to share our experience in the management of the post-COVID-19 patient in two institutions thathave had a high incidence of COVID-19 and to propose general follow-uprecommendations from a clinical and radiological perspective.     

膝痹宁对膝骨关节炎模型大鼠滑膜纤维化的影响

目的观察膝痹宁对膝骨关节炎(KOA)模型大鼠滑膜纤维化的影响。方法大鼠分为空白组、KOA组、膝痹宁组;KOA组、膝痹宁组造模。分别在膝痹宁灌胃治疗的第1、14、28、42、56天测量各组大鼠的膝关节横径;第56天处死大鼠提取滑膜组织,解剖学观察滑膜组织形态;天狼星红染色评估滑膜组织胶原沉积情况;WB和PCR检测纤维化标记物生长转化因子-β(TGF-β)、Ⅰ型胶原α1链(COL1α1)、金属蛋白酶抑制剂1(TIMP1)的蛋白和基因表达。结果膝痹宁用药14天,28天时,膝关节横径变化并不显著,但膝痹宁用药42天,56天时,膝关节横径则较KOA模型明显减小,差异具有统计学意义(P<0.05);用药56天后对大鼠进行膝关节解剖学观察,KOA大鼠滑膜组织较正常大鼠有一定程度的增厚、充血、欠规则;而上述表现在膝痹宁大鼠有所减轻;天狼星红染色显示膝痹宁用药大鼠滑膜组织胶原沉积较少;纤维化标记指标物TGF-β、COL1α1、TIMP1的基因和蛋白表达在膝痹宁组均较KOA组降低,差异具有统计学意义(P<0.05)。结论膝痹宁对能有效减轻KOA滑膜纤维化,以“温经活血”立法的中药复方对组织纤维化具有良性干预效应。     

Bilateral total deafness after preparation of wild boar meat

IntroductionStreptococcus suis is responsible for a zoonosis for which Suidae (pigs and wild boars) constitute the reservoir, mainly in Asia, with a much lower prevalence in Europe. The predominant clinical manifestation is meningitis, possibly resulting in deafness.Case reportWe report the case of a woman hospitalised for meningitis complicated by labyrinthitis, occurring several hours after preparing a meal composed of wild boar meat. Despite the presence of intracochlear fibrosis, the patient was managed by sequential bilateral cochlear implants.DiscussionThe discussion presents a review of the international literature and describes the mechanisms responsible for hearing loss related to this rare zoonosis.     

实时剪切波弹性成像在拉米夫定治疗乙肝纤维化过程中的疗效评估作用

目的探讨实时剪切波弹性成像在评估拉米夫定治疗乙肝纤维化临床疗效中的作用。方法选取2017年1月～2018年1月我院收治的80例乙肝纤维化患者,根据随机数字法分为对照组和观察组,每组40例。对照组采用常规治疗,观察组在对照组的基础上给予拉米夫定进行治疗,治疗6个月。比较两组治疗前后肝功能、肝纤维化指标,利用实时剪切波弹性成像评估两组治疗前后肝脏弹性模量值及肝穿刺活检情况,并进行比较。结果两组治疗后AST、ALT、TBIL水平均明显低于治疗前,差异有统计学意义(P0.05);观察组治疗后AST、ALT、TBIL水平均明显低于对照组,差异有统计学意义(P0.05);两组治疗后HA、LN、PⅢPN-P、CL-Ⅳ水平及杨氏弹性模量值均显著低于治疗前,差异有统计学意义(P0.05);观察组治疗后HA、LN、PⅢPN-P、CL-Ⅳ水平及杨氏弹性模量值均显著低于对照组,差异有统计学意义(P0.05);与治疗前相比,两组治疗后肝穿刺活检结果均有好转,尤其是汇管区、肝小叶内炎症及肝纤维化改善明显。结论实时剪切波弹性成像作为肝脏硬度定量检测的无创性技术,可用于拉米夫定治疗乙肝纤维化临床疗效评估的重要方法。     

Non alcoholic fatty liver disease and risk of incident diabetes in subjects who are not obese

Background and aims

It is not known whether non alcoholic fatty liver disease (NAFLD) is a risk factor for diabetes in non obese, non centrally-obese subjects. Our aim was to investigate relationships between fatty liver, insulin resistance and a biomarker score for liver fibrosis with incident diabetes at follow up, in subjects who were neither obese nor centrally-obese.

Human epididymis protein 4 (HE4) levels inversely correlate with lung function improvement (delta FEV1) in cystic fibrosis patients receiving ivacaftor treatment

Background

We have recently shown that human epididymis protein 4 (HE4) levels correlate with the severity of cystic fibrosis (CF) lung disease. However, there are no data on how HE4 levels alter in patients receiving CFTR modulating therapy.

Peyronie's disease:a silent consequence of diabetes mellitus

Aim:To investigate the clinical characteristics of patients with Peyronie's disease(PD)and diabetes mellitus(DM).Methods:During an 8-year period,a total of 307 men seen at our outpatient clinic were diagnosed with PD.Clinicalcharacteristics,penile deformities and the erectile status of patients with PD and DM together(n=102)were retro-spectively analyzed and compared to patients with PD alone with no risk factors for systemic vascular diseases(n=97).Results:The prevalence of PD among men with DM and sexual dysfunction was 10.7%.The mean ageof diabetic patients with PD was(55.9±8.9)years;in the no risk factor group it was(48.5±9.0)years(P<0.05).The median duration of DM was 5 years.The majority of diabetic patients with PD(56.0%)presented in the chronicphase(P<0.05),and they were more likely to have a severe penile deformity(>60°)than the no risk factor group(P<0.05).In the diabetic group,the most common presenting symptom was penile curvature(81.4 %),followedby a palpable nodule on the shaft of the penis(22.5%)and penile pain with erection(14.7 %).A total of 19.6 % ofpatients were not aware of their penile deformities in the diabetic group.Erectile function,provided by history and inresponse to intracavernosal injection and a stimulation test,was significantly diminished in patients with PD and DM(P<0.05).Conclusion:DM probably exaggerates the fibrotic process in PD.Diabetic patients with PD have ahigher risk of severe deformity and erectile dysfunction(ED).PD seems to be a silent consequence of DM andshould be actively sought in diabetic men.(Asian J Androl 2006 Jan;8:75-79)     

胰岛素样生长因子结合蛋白、内毒素与肝纤维化

目前胰岛素样生长因子结合蛋白（insulin—like growth—factor—binding protein，IGFBPs）及其超家族功能的研究是国际上的热点。有研究表明IGFBPs与肝纤维化的发生有关，而临床检测和动物实验表明肠源性内毒素血症与肝纤维化的发生发展有着密切关系，同时有研究显示内毒素可诱导循环中某些IGFBPs和其肝脏基因的表达发生变化。
