    胎儿原发性胸水是一种罕见的先天性异常,估计发生率为1:10,000-15,000妊娠,不可预测的临床过程,从自发消退到胎儿死亡。在妊娠第35周进行常规超声检查胎儿评估时,诊断出一例单侧胎儿胸腔积液。在右胸膜腔中发现了大量的回声液体,以及右肺的肺不张,以及心脏和纵隔结构向胸腔左侧移位。该患者还被诊断为羊水过多,并且心室容积不成比例。没有检测到其他胎儿结构异常,也没有水肿症状。胎儿生物识别与胎龄一致。在超声心动图中,胎儿心脏结构和功能正常.胎儿先天性感染筛查试验均为阴性。实验室检查后排除自身免疫性胎儿水肿。没有父母同意进行核型分析。患者出现临床症状,诊断为单纯疱疹病毒感染,口服阿昔洛韦治疗。连续的胎儿超声检查显示,在妊娠第38周,胸腔积液逐渐减少,直至完全消退。妊娠在妊娠第38周结束,剖腹产健康的新生儿。尚未确定妊娠中单纯疱疹病毒感染与胎儿胸腔积液的风险之间是否存在直接关联。胎儿胸腔积液发生率低,新生儿结局难以预测。胎儿胸腔积液的最佳管理应进行进一步研究,以确定最佳的临床实践。
    Fetal primary hydrothorax is a rare congenital anomaly with an estimated incidence of 1:10,000-15,000 pregnancies, with an unpredictable clinical course, ranging from spontaneous resolution to fetal death. A case of unilateral fetal pleural effusion was diagnosed at 35th week of gestation during a routine ultrasonographic fetal assessment in an uncomplicated pregnancy. A large echogenic collection of fluid was revealed in the right pleural cavity, together with atelectasis of the right lung, as well as displacement of heart and mediastinal structures to the left side of thorax. The patient was also diagnosed with polyhydramnios and there was a disproportion of heart ventricles volume. No other fetal structural abnormalities were detected and there were no symptoms of edema. Fetal biometrics was consistent with the gestational age. In echocardiography, fetal heart was structurally and functionally normal. Screening tests for congenital infections of the fetus were negative. Autoimmune fetal hydrops was excluded after laboratory tests. There was no parents\' consent for the analysis of the karyotype. The patient presented clinical symptoms and was diagnosed with Herpes simplex virus infection and was treated with oral acyclovir. Serial fetal ultrasound exams showed gradual decrease in pleural fluid volume up to complete resolution in 38th week of pregnancy. Pregnancy was ended in the 38th week of gestation with a cesarean delivery of a healthy neonate. It is yet to be determined if there is a direct association between Herpes simplex virus infection in pregnancy and the risk of fetal pleural effusion. The incidence of fetal pleural effusion is low and the neonatal outcome difficult to be predicted. The optimum management of fetal pleural effusion should be subject to further studies to determine the best clinical practice.

    免疫功能低下的患者有发生非典型单纯疱疹病毒(HSV)感染的风险,很容易被误诊.我们介绍了一例69岁的女性,她正在接受甲氨蝶呤和托法替尼治疗已知的类风湿性关节炎病例。在出现细菌性脑膜炎继发的癫痫持续状态后,她在神经科护理下被送入ICU。她抱怨红斑基底上有一组囊泡,伴有灼烧感,有出血性外壳的侵蚀延伸到朱红唇,疼痛性的口腔粘膜糜烂,涉及口腔,Palatine,和舌头。临床鉴别诊断为单纯疱疹感染,寻常型天疱疮,副肿瘤性天疱疮,早期药物诱发的Stevens-Johnson综合征,多形性大红斑,和甲氨蝶呤引起的粘膜炎。由于演讲是非典型的,开始类固醇治疗.随后的组织病理学显示与疱疹病毒感染一致的感染性皮炎。在停止类固醇治疗并开始抗病毒药物后,患者的症状在一周内得到改善。对于免疫功能低下患者单纯疱疹感染的非典型临床表现,临床认识有所提高。HSV感染应与其他囊泡疾病一起纳入鉴别诊断。
    Immunocompromised patients are at risk of developing atypical herpes simplex virus (HSV) infection, which can be easily misdiagnosed. We present a case of a 69-year-old female who was receiving methotrexate and tofacitinib for a known case of rheumatoid arthritis. She was admitted to the ICU under neurology care after presenting with status epilepticus secondary to bacterial meningitis. She complained of a group of vesicles on the erythematous base accompanied by a burning sensation, erosions with a hemorrhagic crust that extended onto the vermilion lip, and painful oral mucosa erosion that involve the buccal, palatine, and tongue. The clinical differential diagnosis was herpes simplex infection, pemphigus vulgaris, paraneoplastic pemphigus, early drug-induced Stevens-Johnson syndrome, erythema multiform major, and methotrexate-induced mucositis. As the presentation was atypical, steroid treatment was initiated. Subsequent histopathology showed infectious dermatitis consistent with herpes virus infection. After discontinuing steroid treatment and starting an antiviral drug, the patient\'s symptoms improved within a week. There has been heightened clinical awareness about the atypical clinical presentation of herpes simplex infection in immunocompromised patients. HSV infection should be included in the differential diagnosis along with other vesiculobullous diseases.

    背景:MS患者管理的复杂性不断增加。因此,MS护理部门需要多学科的方法,包括传染病专家,以最大程度地减少与疾病和DMT相关的传染病并发症的风险。
    方法:我们回顾性评估了2015年至2019年在MS中心进行的传染病咨询。
    结果:在1088例患者中,我们确定了107例至少有一次传染病咨询的患者。我们发现,从2015年到2019年,咨询数量逐步增加。近一半的咨询是在开始MS治疗时要求的。最常见的请求是慢性或急性感染。最普遍的感染因子是疱疹病毒科和结核分枝杆菌。抗生素或抗病毒治疗以及预防性治疗或疫苗接种共同代表了咨询的最常见结果。最后,治疗延迟与预防性治疗或疫苗接种的建议显著相关.
    结论:人们越来越认识到MS的潜在感染并发症和暴露于DMT。MS神经科医生和传染病专家之间的互动对于最大程度地降低与疾病和DMT相关的感染风险至关重要。随着MS诊断时从并发症管理逐步转向更广泛的预防检查,包括疫苗接种和预防性治疗。
    BACKGROUND: The complexity of the MS patient\'s management is constantly growing. Consequently, the MS care unit requires a multidisciplinary approach, including an infectious disease specialist to minimise the risk of infectious complications related both to the disease and DMTs.
    METHODS: We retrospectively evaluated the infectious disease consultations performed from 2015 to 2019 in our MS centre.
    RESULTS: We identified 107 patients with at least one infectious disease consultation out of 1088 patients. We found a progressive increase in the number of consultations from 2015 to 2019. Nearly half of the consultations were requested at the time of starting MS treatment. The most frequent requests were represented by chronic or acute infections. The most prevalent infectious agents were Herpesviridae and Mycobacterium tuberculosis. Antibiotic or antiviral treatment and prophylactic treatment or vaccination represented together the most frequent outcomes of the consultations. Finally, a treatment delay was significantly associated with the advice of a prophylactic treatment or of a vaccination.
    CONCLUSIONS: There is an increasing awareness of the potential infectious complications of MS and of exposure to DMTs. The interaction between the MS neurologist and infectious disease specialist is fundamental to minimise the infectious risk related to the disease and to the DMTs, with a progressive shift from complication management to a broader prevention workup at the time of MS diagnosis, including both vaccination and prophylactic treatments.

    未经授权:评估重症COVID-19患者呼吸道样本中单纯疱疹和巨细胞病毒感染的患病率,其在SARS-CoV-2感染早期的结局和死亡率以及地塞米松治疗的影响中的作用。
    UNASSIGNED:纳入了2020年3月至2021年1月在ICU接受治疗的所有机械通气COVID-19患者。通过定量实时PCR测试呼吸道标本中的单纯疱疹病毒(HSV)1、2型和巨细胞病毒(CMV)。在有和没有HSV-1感染的队列中比较临床参数。
    未经证实:134例患者,中位年龄为72.5岁(73.0%为男性,包括n=98)。61例(45.5%)患者发生HSV-1再激活,机械通气后中位数9(7-13)天。再激活的主要因素是在ICU的住院时间(24天比13天,p<0.001)和机械通气持续时间(417vs214小时,p<0.001)。单变量分析中,地塞米松治疗和免疫抑制史与HSV感染无关(39vs41,p=0.462和27.9%vs23.3%,分别为p=0.561)。在有和没有HSV感染的队列中,ICU和医院死亡率没有显着差异(57.4%vs45.2%,p=0.219)。
    UNASSIGNED:我们的研究表明,在重症COVID-19患者中,HSV感染的患病率很高,出乎意料地高于CMV感染的患病率,并且与地塞米松治疗无关。研究队列中HSV和CMV的主要危险因素是ICU住院时间和机械通气时间。因此,我们建议对危重COVID-19患者进行这些病毒合并感染的常规监测,并考虑对这些患者进行治疗.
    UNASSIGNED: To assess the prevalence of Herpes simplex and Cytomegalovirus infection in respiratory samples of critically-ill COVID-19 patients, its role in outcome and mortality and the influence of dexamethasone treatment in the early stage of SARS-CoV-2 infection.
    UNASSIGNED: All mechanically ventilated COVID-19 patients treated on ICU between March 2020 and January 2021 were included. Respiratory specimens were tested for Herpes simplex virus (HSV) type 1, 2 and Cytomegalovirus (CMV) by quantitative real-time PCR. Clinical parameters were compared in the cohorts with and without HSV-1- infection.
    UNASSIGNED: 134 patients with a median age of 72.5 years (73.0% male, n=98) were included. HSV-1 reactivation occurred in 61 patients (45.5%), after median 9 (7-13) days of mechanical ventilation. The main factor for reactivation was length of stay on ICU (24 days vs 13 days, p<0.001) and duration of mechanical ventilation (417 vs 214 hours, p<0.001). Treatment with dexamethasone and a history of immunosuppression did not associate with HSV-infection in the univariate analysis (39 vs 41, p=0.462 and 27.9% vs 23.3%, p=0.561, respectively). Both ICU and hospital mortality were not significantly different in the cohorts with and without HSV-infection (57.4% vs 45.2%, p=0.219).
    UNASSIGNED: Our study shows a high prevalence of HSV-infection in critically-ill COVID-19 patients which was unexpectedly higher than the prevalence of CMV-infections and unrelated to dexamethasone treatment. The main risk factors for HSV and CMV in the studied cohorts were the length of ICU stay and duration of mechanical ventilation. Therefore, we recommend routine monitoring of critically ill COVID-19 patients for these viral co-infections and consider treatment in those patients.

    Herpes simplex infection is the most common infection among the human immunodeficiency virus-infected individuals. However, the atypical manifestations of herpes simplex virus may confound even an astute physician. Hand involvement is rarely associated with genital herpes infection and the involvement of widespread areas healing with debilitating scarring is uncommon.

    Background Despite being variable and poorly characterized, the reported cutaneous manifestations of coronavirus disease 2019 (COVID-19) are of increasing concern. Methodology This study aimed to determine the prevalence and possible association between COVID-19 and herpes simplex virus (HSV) infection. A nine-item questionnaire was sent to 120 polymerase chain reaction-confirmed COVID-19 patients with a response rate of 66.67%. This cross-sectional observational study included 80 patients with mild-to-moderate COVID-19 infection who did not require hospitalization or steroid therapy. Results One or more HSV infections were observed in 28 patients (35%) with COVID-19 infection, including 10 (35.7%) males and 18 (64.29%) females. Of the 28 patients, fever was reported in 17 (75%) during COVID-19. Most of the respondents (78%) described a single HSV reactivation, 14.29% had two attacks, and 7.14% experienced three attacks. Compared to previous non-COVID-19-related HSV reactivation, the COVID-19-related attacks were more severe in 12 (42.85%) patients, equally severe in five (17.85%) patients, and less severe in one (3.57%) patient. Interestingly, 10 (35.71%) patients developed an initial symptomatic HSV attack during COVID-19 infection. Conclusions This study demonstrated a possible association between COVID-19 infection and primary HSV infection or reactivation. COVID-19 direct neuronal effect in addition to COVID-19-related psychological stress, fever, and immunological dysregulation could play a potential role in HSV reactivation or primary infection during COVID-19.

    Epstein-Barr virus (EBV) is a double-stranded virus that shows tropism for B-cell lymphocytes. EBV-infected patients usually present with tonsillitis/pharyngitis, cervical lymphadenopathy and fever, but an atypical presentation can mimic lymphoproliferative disease. We present the case of a 77-year-old woman with asthenia, fever, oral ulcers and peripheral lymphadenopathy. After extensive evaluation, including anatomopathological and immunocytochemical examination of excisional lymph node biopsy samples, it was still not clear whether the patient had EBV infection or diffuse large B-cell lymphoma. In this case report, the authors describe how it can be difficult to differentiate between two different, although related, entities, making diagnosis of lymphoma highly challenging.
    UNASSIGNED: Lymph node biopsy findings may result in lymphoma being misdiagnosed as acute Epstein-Barr virus infection.Immunophenotypic analysis can occasionally be insufficient to establish the clonal nature of the disease.Timely diagnosis of lymphoma is necessary so that immunochemotherapy can be initiated and clinical improvement achieved.

    Recurrent anogenital herpes simplex virus infections are common in patients with human immunodeficiency virus (HIV), of whom approximately 5% develop resistance to acyclovir. We present a case of a 49-year-old man with HIV who had an 8-year history of recurrent left inguinal herpes simplex virus type 2 ulcerations. He initially responded to oral acyclovir, but developed resistance to acyclovir and eventually foscarnet. The lesion progressed to a large hypertrophic mass that required surgical excision, which led to resolution without recurrences. Our case highlights the importance of surgical excision as a treatment option in refractory herpes simplex virus anogenital infections.

    BACKGROUND: Sexually transmitted infections (STIs) plays a major role in the spread of Human immunodeficiency virus (HIV) due to common route of transmission. These infections display an epidemiological synergy with HIV.
    OBJECTIVE: The aim of this study was to analyse the correlation of CD4 T lymphocyte cell count, HIV-1 plasma viral load with Reproductive tract infections/Sexually transmitted infections (RTIs/STIs) in HIV infected females.
    METHODS: The study included 60 HIV infected females. An informed consent was taken from all the study subjects. Relevant specimens (genital specimen and blood) were collected for laboratory diagnosis of various RTIs/STIs, CD4 cell count and plasma viral load estimation.
    RESULTS: Mean CD4 count of females with bacterial vaginosis, vaginal candidiasis, trichomoniasis, syphilis and herpes simplex infection were lower as compared to other HIV infected cases and mean plasma viral load of bacterial vaginosis, vaginal candidiasis, trichomoniasis and syphilis were higher as compared to other HIV infected cases but this difference was not statistically significant.
    CONCLUSIONS: This study highlights the importance of routine screening for STIs/RTIs of all the HIV infected females for RTIs/STIs irrespective of CD4 cell count and plasma viral load.
