    一种罕见的局部侵袭性血管肿瘤,青少年鼻咽血管纤维瘤(JNA)主要影响男性青少年。本文描述了一名14岁的男性患者,他表现为嗜睡和复发性鼻出血,这是JNA的症状。CT和MRI扫描证实血管肿块具有明显的局部侵袭,起源于蝶腭孔。CT血管造影后,这揭示了肿瘤的大量血液供应,并有助于有效切除,设计了一个有针对性的手术策略。组织病理学证实了肿瘤的良性性质,手术成功,患者顺利康复。这个案例增加了关于JNA的小文献。它强调了医疗保健专业人员在管理疾病时需要了解早期识别和仔细的术前准备的要求。
    A rare and locally aggressive vascular tumor, juvenile nasopharyngeal angiofibroma (JNA) mostly affects male teenagers. This paper describes a 14-year-old male patient who presented with lethargy and recurrent nasal bleeding, which are symptoms of JNA. CT and MRI scans confirmed a vascular mass with a significant local invasion originating from the sphenopalatine foramen. After a CT angiography, which revealed the tumor\'s large blood supply and helped with efficient excision, a focused surgical strategy was designed. Histopathology verified the benign nature of the tumor, and the operation was successful and the patient had a smooth recovery. This case adds to the little literature on JNA. It highlights the need for healthcare professionals to be aware of the requirement of early identification and careful presurgical preparation in managing the illness.

    以前从未探索过与普萘洛尔治疗婴儿血管瘤(IH)相关的治疗负担(BOT)。修改后的验证问卷,治疗负担问卷,和一对一半结构化访谈用于评估普萘洛尔用于IH的BOT。在80名护理人员中,总体负担得分非常低,为10分之1.2;访谈的主题分析将主题分为行政管理,监测,金融,和相关的异常。普萘洛尔治疗IH的BOT非常低,但可以通过提供与喂养频率和低血糖风险相关的基于年龄的风险分层来进一步降低。关于睡前剂量时间的务实建议,减少生命体征监测的频率。
    The burden of treatment (BOT) related to propranolol treatment for infantile hemangiomas (IH) has never previously been explored. A modified validated questionnaire, the Treatment Burden Questionnaire, and one-on-one semi-structured interviews were used to assess the BOT for propranolol for IH. Out of 80 caregivers, the overall burden score was very low at 1.2 out of 10; thematic analysis of interviews grouped themes into administration, monitoring, financial, and associated anomalies. The BOT of propranolol for IH is very low but could be reduced further by offering age-based risk stratification related to feeding frequency and risk of hypoglycemia, pragmatic advice around timing of doses before sleep, and reducing frequency of vital sign monitoring.

    方法:在2017年至2020年期间,共有1033例IH患者被纳入研究。IH患者按性别与对照组相匹配。训练有素的调查人员从参与者那里收集了详细信息。采用Logistic回归模型进行多因素分析。
    结果:统计分析表明流产史(比值比[OR]=4.275;95%置信区间[CI][3.195,5.720]),妊娠期贫血(OR=4.228;95%CI[3.083,5.799]),早产胎膜早破(PPROM)(OR=3.182;95%CI[1.359,7.454]),前置胎盘(OR=2.440;95%CI[1.787,3.333]),先兆流产(OR=2.290;95%CI[1.726,3.039]),胎膜早破(PROM)(OR=1.785;P<0.05),孕酮用量(OR=1.614;P<0.001)和羊水量异常(OR=1.499;P<0.05)是IH的独立危险因素。妊娠期糖尿病(GDM)(OR=0.607;95%CI[0.464,0.794]),多胎妊娠(OR=0.407;95%CI[0.232,0.713]),甲状腺功能减退(OR=0.407;95%CI[0.227,0.730])和子宫肌瘤(OR=0.393;95%CI[0.250,0.618])可降低IH的风险。
    结论:母婴因素与IH的发生密切相关。我们的研究为指导进一步探索IH的发病机制提供了可靠的线索。
    背景:ClinicalTrials.gov,NCT03331744。婴幼儿血管瘤是儿童最常见的良性肿瘤,严重影响外观和功能,甚至威胁生命。发病机制尚不明确,大样本量的孕产妇和围产期的详细病例对照研究将有助于制定个性化和精确的治疗方案,对高危儿童进行早期及时干预,改善预后。我们的研究发现流产史,妊娠期贫血,早产胎膜早破(PPROM),前置胎盘,威胁流产,胎膜早破(PROM),孕酮使用和羊水量异常是IH的独立危险因素。
    BACKGROUND: Infantile hemangioma (IH) is the most common benign tumor in infancy, but information about its pathogenesis is limited. The aim of this study was to determine maternal and perinatal risk factors for IH.
    METHODS: A total of 1033 IH patients were enrolled in the study between 2017 and 2020. IH patients were matched with controls by sex. Trained investigators collected detailed information from the participants. Logistic regression models were used for multivariate analysis.
    RESULTS: The statistical analysis demonstrated that miscarriage history (odds ratio [OR] = 4.275; 95% confidence interval [CI] [3.195, 5.720]), anemia in pregnancy (OR = 4.228; 95% CI [3.083, 5.799]), preterm premature rupture of membranes (PPROM) (OR = 3.182; 95% CI [1.359, 7.454]), placenta previa (OR = 2.440; 95% CI [1.787, 3.333]), threatened miscarriage (OR = 2.290; 95% CI [1.726, 3.039]), premature rupture of membranes (PROM) (OR = 1.785; P < 0.05), progesterone use (OR = 1.614; P < 0.001) and abnormal amniotic fluid volume (OR = 1.499; P < 0.05) were independent risk factors for IH. Gestational diabetes mellitus (GDM) (OR = 0.607; 95% CI [0.464, 0.794]), multiple gestations (OR = 0.407; 95% CI [0.232, 0.713]), hypothyroidism (OR = 0.407; 95% CI [0.227, 0.730]) and uterine fibroids (OR = 0.393; 95% CI [0.250, 0.618]) may reduce the risk of IH.
    CONCLUSIONS: Maternal and perinatal factors are closely associated with IH occurrence. Our study provides reliable clues to guide further exploration of the pathogenesis of IH.
    BACKGROUND: ClinicalTrials.gov, NCT03331744. Infantile hemangioma is the most common benign tumor in children, which seriously affects appearance and function and even threatens life. The pathogenesis is not clear, a detailed case-control study of the maternal and perinatal periods with a large sample size will facilitate the development of individualized and precise treatment, early and timely interventions for high-risk children and improvement of prognosis. Our study found that miscarriage history, anemia in pregnancy, preterm premature rupture of membranes (PPROM), placenta previa, threatened miscarriage, premature rupture of membranes (PROM), progesterone use and abnormal amniotic fluid volume were independent risk factors for IH.

    大鼠肠系膜淋巴结血管肿瘤的发生率可能有所不同,当治疗组的发病率高于对照组时,需要对潜在的致瘤性风险进行适当的评估。在一项为期2年的luseogliflozin大鼠致癌性研究中,一种用于治疗2型糖尿病的选择性钠依赖性葡萄糖协同转运蛋白2抑制剂,高剂量男性肠系膜淋巴结中血管瘤和血管肉瘤的总数略有增加,但有统计学意义.作为luseogliflozin风险评估的一部分,在一项大鼠致癌性研究中,通过使用对照和高剂量男性的PCNA和CD34双重免疫组织化学染色标本进行图像分析,检查了其对肠系膜淋巴结中血管增殖潜能的影响.此外,进行VEGF的免疫组织化学染色以检测增强的血管生成。在没有血管瘤/血管肉瘤的高剂量男性中,没有观察到PCNA/CD34阳性细胞数量的增加,也没有观察到VEGF表达模式的改变.另一方面,在患有血管瘤/血管肉瘤的高剂量男性中,肿瘤区域PCNA阳性细胞数量增加,在对照男性中,血管瘤/血管肉瘤的数量约为血管肉瘤的一半。总之,在接受luseogliflozin的高剂量男性患者的肠系膜淋巴结中未检测到导致血管增殖/肿瘤的潜在变化.
    The incidence of mesenteric lymph node vascular tumors can vary in rats, and appropriate assessment of potential risk of tumorigenicity is needed when the incidence is higher in treated groups than in a control group. In a 2-year rat carcinogenicity study of luseogliflozin, a selective sodium-dependent glucose co-transporter 2 inhibitor for the treatment of type 2 diabetes mellitus, there was a slight but statistically significant increase in the total number of hemangiomas and hemangiosarcomas in the mesenteric lymph nodes in males at a high-dose. As part of the risk assessment for luseogliflozin, its effect on the vascular proliferation potential in the mesenteric lymph nodes was examined in a rat carcinogenicity study by performing an image analysis using specimens with double immunohistochemical staining for PCNA and CD34 in control and high-dose males. In addition, immunohistochemical staining for VEGF was performed to detect enhanced angiogenesis. In the high-dose males that did not have a hemangioma/hemangiosarcoma, neither an increased number of PCNA/CD34-positive cells nor changes in the expression pattern of VEGF was observed. On the other hand, in the high-dose males that had a hemangioma/hemangiosarcoma, the number of PCNA-positive cells was increased in the tumor areas, and the number in the hemangioma/hemangiosarcoma was approximately one-half of that in the hemangiosarcoma in the control male. In conclusion, no potential change leading to vascular proliferation/tumors was detected in the mesenteric lymph nodes of high-dose males receiving luseogliflozin.

    背景:由于增殖和灌注增加,婴儿血管瘤(IH)最初是温暖的,然后随着凋亡和灌注减少而逐渐消退。IH治疗反应的客观定量评估对于改善预后至关重要。我们应用了一种功能成像方法,动态红外(IR)热成像,调查IH状态与对照皮肤以及随时间的变化。
    方法:一项初步的前瞻性观察性研究是对25名患有浅表或混合IHs(<19个月)的受试者进行59次临床访问。IHs和控制站点的红外图像,标准化的彩色图像,并获得了三维图像。用视频IR热成像记录施加和去除冷应力后的组织反应。结果包括冷却(AUCcool)和再加热(AUCrw)期间曲线下的面积以及热强度分布图。
    结果:与未受累组织相比,IHs的AUCcool和AUCrw明显更高,冷却速度更慢,表明热量更大,可能是由于IH的灌注和代谢增加。红外分布图显示特定区域的高温和低温。IH热活性的显著变化反映在差异(AUCcool-AUCrw)中,2.2个月时的6.2增加到12.8个月时的37.6。IH冷却速率随年龄增加而增加,表明恢复较慢,并解释为减少增殖和/或退化。
    结论:动态红外热像仪具有良好的耐受性,适合临床的定量功能成像模式,特别是当结构变化时,即,高度,volume,颜色,不容易观察到。它可能有助于监测进展,个体化治疗,并评估治疗方法。
    背景:www.clinicaltrials.gov(标识符NCT02061735)。
    BACKGROUND: Infantile hemangiomas (IH) are initially warm due to increased proliferation and perfusion then involute with apoptosis and reduced perfusion. Objective quantitative evaluation of IH treatment response is essential for improving outcomes. We applied a functional imaging method, dynamic infrared (IR) thermography, to investigate IH status versus control skin and over time.
    METHODS: A preliminary prospective observational study was conducted among 25 subjects with superficial or mixed IHs (< 19 months) over 59 clinic visits. Infrared images of IHs and control sites, standardized color images, and three-dimensional images were obtained. Tissue responses following application and removal of a cold stress were recorded with video IR thermography. Outcomes included areas under the curve during cooling (AUCcool ) and rewarming (AUCrw ) and thermal intensity distribution maps.
    RESULTS: AUCcool and AUCrw were significantly higher and cooling rate slower for IHs versus uninvolved tissue indicating greater heat, presumably due to greater perfusion and metabolism for the IH. IR distribution maps showed specific areas of high and low temperature. Significant changes in IH thermal activity were reflected in the difference (AUCcool - AUCrw ), with 6.2 at 2.2 months increasing to 37.6 at 12.8 months. IH cooling rate increased with age, indicating slower recovery, and interpreted as reduced proliferation and/or involution.
    CONCLUSIONS: Dynamic IR thermography was a well-tolerated, quantitative functional imaging modality appropriate for the clinic, particularly when structural changes, i.e., height, volume, color, were not readily observed. It may assist in monitoring progress, individualizing treatment, and evaluating therapies.
