scurvy

  • 文章类型: Case Reports
    镰刀,维生素C缺乏引起的疾病,由于胶原蛋白产生和抗氧化功能缺陷,其特征是多系统疾病综合征。这种情况在这个现代时代很少见;因此,它通常不在鉴别诊断范围内.广泛的临床表现通常被忽略为其他系统性疾病,导致广泛的调查延误了诊断。在这里,我们报告了一例8岁的自闭症谱系障碍男孩,他有下肢疼痛和其他全身症状.检查发现上肢和下肢有多个色素沉着过多的疤痕和牙龈色素沉着过多。有挑食习惯的病史和影像学检查结果支持的临床症状,根据低含量的抗坏血酸怀疑并随后证实了镰刀病。补充维生素C和适当的营养支持,病人恢复得很好。
    Scurvy, a condition caused by vitamin C deficiency, is characterized by a syndrome of multisystem disorder due to defective collagen production and antioxidative function. This condition is infrequent in this modern era; thus, it is often not within the list of differential diagnoses. The broad clinical picture is generally overlooked as other systemic illnesses, resulting in an extensive investigation that delays the diagnosis. Herein, we report a case of an 8-year-old boy with underlying autism spectrum disorder who presented with lower limb pain and other constitutional symptoms. Examination revealed multiple hyperpigmented scars over the upper and lower limbs and gingival hyperpigmentation. With history of picky eating habits and clinical symptoms supported by radiographic findings, scurvy was suspected and subsequently confirmed based on a low level of ascorbic acid. With vitamin C supplementation and proper nutritional support, the patient recovered well.

    镰刀是一种由抗坏血酸(维生素C)缺乏引起的营养性疾病。尽管目前它是一种罕见的疾病,在限制饮食患者的紫癜和关节炎的鉴别诊断中应该考虑它。我们介绍了一名49岁男子的病例,该男子有营养失调史,并因广泛性紫癜和髋关节而被送往我们医院。根据回忆和实验室发现,风湿病,感染性和血液学病因被排除.最后,在维生素C水平低下和对营养补充剂的惊人反应后,才诊断为镰刀病。我们将此病例与医学文献中报道的19例类似病例进行了比较。
    Scurvy is a nutritional disease caused by ascorbic acid (vitamin C) deficiency. Althought currently it is a rare disease, we should considerer it in the differential diagnosis of purpura and arthritis in patients with restrictive diets. We present the case of a 49-year-old man with a history of a nutritional disorder presented to our hospital with generalized purpura and hemarthros. Following the anamnesis and laboratory findings, rheumatological, infectious and hematological etiologies were excluded. Finally, the diagnosis of scurvy was made upon demostration poor levels of vitamin C and a spectacular response to nutritional supplements. We compare this case with 19 similar cases reported in the medical literature.

    镰刀是一种罕见的病理状况,由持续的膳食维生素C缺乏引起。放射学变得很关键,因为对镰刀病的诊断过程很复杂,因为它与骨肿瘤相似。一个六岁的男孩,报告在住院前2个月的右大腿持续疼痛和肿胀。临床检查显示右侧大腿有肿块,贫血。右股骨的X线片显示广泛的骨质疏松改变,\"Trümmerfeld区\",\"弗兰克尔线\",“骨盆骨折”,\"Wimberger戒指标志\",骨phy旁骨膜下血肿。我们机构在过去十年中没有任何此类案例,这突出了这种介绍的独特性。组织病理学评估产生非典型结果,提示对左股骨和胸部进行进一步的影像学评估。随后的发现证实了经典的“蝎子念珠”的陈述,表明了镰刀。高剂量补充维生素C后,患者的症状逐渐缓解。镰刀病主要表现为肌肉骨骼表现。血浆维生素C水平评估是诊断的金标准,但它目前在我们国家是无法进入的。因此,影像学评估揭示了该疾病的病理特征。在胸片上,\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\相比之下,长骨表现出镰刀症的标志:弥漫性骨质减少,\"弗兰克尔线\",\"Trümmerfeld区\",“骨盆骨折”,\"Wimberger戒指标志\",骨phy旁骨膜下血肿。维生素C的及时干预阻碍了严重并发症的进展。放射学是诊断小儿镰刀病不可或缺的工具,尤其是在无法评估维生素C血清水平的发展中国家。
    Scurvy is an infrequent pathological condition resulting from a sustained dietary vitamin C deficiency. Radiology becomes pivotal because the diagnostic process for scurvy can be intricate, given its resemblance to bone neoplasms. A 6-year-old boy, reported persistent pain and swelling in the right thigh for 2 months prior to hospitalization. Clinical examination revealed a mass localized in the right thigh and anemia. A radiograph of the right femur demonstrated extensive osteopenic changes, \"Trümmerfeld zone\", \"Frankel line\", \"Pelkin fracture\", \"Wimberger ring sign\", and para-epiphyseal subperiosteal hematoma. The absence of any such cases in our institution over the preceding decade emphasizes the uniqueness of this presentation. Histopathological evaluation yielded atypical results, prompting further radiographic assessment of the left femur and thorax. The subsequent findings corroborated the classic \"scorbutic rosary\" presentation, indicative of scurvy. The patient\'s symptoms gradually resolved with high-dose supplementation of vitamin C. Scurvy predominantly presents with musculoskeletal manifestations. Plasma vitamin C level assessment is the gold standard for the diagnosis, but it is currently inaccessible in our nation. Consequently, radiographic evaluation reveals pathognomonic features of the disorder. In thoracic radiographs, the \"scorbutic rosary\" presentation is evident. In contrast, long bones exhibit hallmarks of scurvy: diffuse osteopenia, \"Frankel line\", \"Trümmerfeld zone\", \"Pelkin fracture\", \"Wimberger ring sign\", and para-epiphyseal subperiosteal hematoma. Prompt intervention with vitamin C thwarts the progression to severe complications. Radiology is an indispensable tool in diagnosing pediatric scurvy, especially in developmental countries where the assessment of vitamin C serum levels is inaccessible.

    镰刀是一种罕见的疾病,其特征是缺乏膳食维生素C。从历史上看,这是一种在长期海洋航行的背景下教授的疾病,维生素摄入量有限,现在在发达国家很少见。经典的体检结果包括牙龈出血,卵泡周出血,和开瓶器的头发。我们讨论了一名15岁女性的镰刀病病例,其最初的表现表明在急诊科中发现了更常见的诊断。她的课程因之前的神经性厌食症病史和缺乏必要维生素的限制性饮食而变得复杂。一旦患者的饮食习惯被确定,详细的身体检查揭示了特征性的发现。她随后口服维生素C补充剂出院,并计划进行门诊随访以监测症状。
    Scurvy is a rare condition characterized by a deficiency in dietary vitamin C. Historically a disease taught in the context of long ocean voyages with limited vitamin intake, it is now rare in developed nations. The classical physical exam findings include gingival bleeding, perifollicular hemorrhages, and corkscrew hairs. We discuss the case of a 15-year-old female with scurvy whose initial presentation suggested more common diagnoses seen in the emergency department setting. Her course was complicated by a prior history of anorexia nervosa and a restrictive diet that lacked necessary vitamins. Once the patient\'s dietary habits were identified, a detailed physical exam revealed the characteristic findings. She was subsequently discharged with oral vitamin C supplements and was scheduled for outpatient follow-up to monitor symptoms.

    目的:本研究旨在确定基底旁下表面孔隙和骨膜下新骨形成的病因。
    方法:总共199名年龄在妊娠36周至3.5岁之间的非成人个体,从英国总共12个考古遗址中,包括铁器时代(n=43),Roman(n=12),和后中世纪(n=145)遗址,还有一个保存完好的巴拉利斯。
    方法:将基底分为六段,具有多孔性(微观和宏观)和骨膜下新骨形成记录在下表面的珠光体和非珠光体个体。使用生物学方法开发的古病理学文献中的标准诊断了镰刀。
    结果:在所分析的6个区段中,有4个区段没有统计学上的显著差异。在非火山岩和火山岩个体中,年龄与微孔之间存在显着负相关。在珠光体和非珠光体个体之间观察到骨膜下新骨形成的显着差异。
    结论:在非成人骨骼遗骸(小于3.5年)的镰刀病宏观评估中,不应考虑基底下部的微孔性。
    结论:本研究强调了在过去人群中过度诊断为镰刀病的风险。
    结论:1岁以下个体骨骼的生理(正常)和病理(异常)骨骼变化难以区分。
    未来的研究应侧重于对3.5岁以上个体的分析。
    OBJECTIVE: This research aims to determine the aetiology of porosity and subperiosteal new bone formation on the inferior surface of the pars basilaris.
    METHODS: A total of 199 non-adult individuals aged 36 weeks gestation to 3.5 years, from a total of 12 archaeological sites throughout the UK, including Iron Age (n=43), Roman (n=12), and post-medieval (n=145) sites, with a preserved pars basilaris.
    METHODS: The pars basilaris was divided into six segments, with porosity (micro and macro) and subperiosteal new bone formation recorded on the inferior surface in scorbutic and non-scorbutic individuals. Scurvy was diagnosed using criteria from the palaeopathological literature that was developed using a biological approach.
    RESULTS: There was no statistically significant difference in microporosity between scorbutic and non-scorbutic individuals in four out of the six segments analysed. There was a significant negative correlation between age and microporosity in non-scorbutic and scorbutic individuals. A significant difference in subperiosteal new bone formation was observed between scorbutic and non-scorbutic individuals.
    CONCLUSIONS: Microporosity on the inferior pars basilaris should not be considered among the suite of lesions included in the macroscopic assessment of scurvy in non-adult skeletal remains (less than 3.5 years).
    CONCLUSIONS: This study highlights the risk of over diagnosing scurvy in past populations.
    CONCLUSIONS: It is difficult to distinguish between physiological (normal) and pathological (abnormal) bone changes in the skeleton of individuals less than one year of age.
    UNASSIGNED: Future research should focus on the analysis of individuals over 3.5 years of age.

    背景:维生素C缺乏,或者镰刀病,是罕见的,但对饮食不良的儿童构成风险,资源有限,或吸收不良的问题。在全球发育迟缓的儿童中,有限制性或选择性饮食习惯的儿童也可能很常见。自闭症谱系障碍,和身体残疾。症状包括疲劳,烦躁,关节和肌肉疼痛,关节膨胀,水肿,牙龈肿胀,容易擦伤,和延迟的伤口愈合。早期识别和及时干预对于预防儿童有症状的维生素C缺乏症的进展至关重要。
    方法:我们介绍了一例因怀疑复发性LennoxGastaut综合征继发发育迟缓的13岁男孩,严重,和非典型IgA血管炎。他表现出烦躁,食欲不振,瘀斑和瘀斑下肢病变,单侧牙龈肿胀,严重的关节炎,外周水肿,严重的体重减轻,贫血,并提高了炎症标志物。在做出镰刀病诊断之前进行了多次调查。手术发现有多个松动牙齿的易碎牙龈组织,毛囊角化过度和毛囊周围红细胞外渗的皮肤活检,和典型的X线检查结果导致了镰刀病的诊断。
    结论:在表现为肌肉骨骼问题的患者中,应仔细考虑作为鉴别诊断,粘膜皮肤投诉,和全身症状,如不适,虚弱,烦躁,和食欲不振。一个集中和详细的饮食历史寻找缺乏良好的维生素C来源可以是这种差异的一个简单的指标。成像研究揭示典型特征也可以帮助做出诊断。揭示病理特征的皮肤病理学可以增加诊断的确定性。在没有其他一切的情况下,对适当剂量的维生素C治疗的快速反应具有诊断和治疗作用。
    BACKGROUND: Vitamin C deficiency, or scurvy, is rare but poses risks for children with poor diets, limited resources, or malabsorption issues. It may also be common in children with restrictive or selective dietary habits in children with global developmental delay, autism spectrum disorder, and physical disabilities. Symptoms include fatigue, irritability, joint and muscle pain, joint swellings, edema, swollen gums, easy bruising, and delayed wound healing. Early recognition and prompt intervention are essential to prevent the progression of symptomatic vitamin C deficiency in children.
    METHODS: We present a case of a 13-year-old boy with developmental delay secondary to Lennox Gastaut syndrome referred for suspected recurrent, severe, and atypical IgA vasculitis. He presented with irritability, loss of appetite, petechial and ecchymotic lower limb lesions, unilateral gum swelling, severe arthritis, peripheral oedema, severe weight loss, anaemia, and raised inflammatory markers. Multiple investigations were performed before the diagnosis of scurvy was made. A surgical finding of friable gingival tissue with multiple loose teeth, a skin biopsy with follicular hyperkeratosis and extravasated perifollicular red blood cells, and a typical X-ray finding led to the diagnosis of scurvy.
    CONCLUSIONS: Scurvy should be given careful consideration as a differential diagnosis in patients presenting with musculoskeletal issues, mucocutaneous complaints, and constitutional symptoms such as malaise, asthenia, irritability, and loss of appetite. A focused and detailed dietary history looking for a lack of good sources of vitamin C can be an easy indicator of this differential. Imaging studies revealing the typical features can also help make the diagnosis. Pathology of the skin revealing pathognomonic features can add to the certainty of the diagnosis. In the absence of all else, the rapid response to treatment with an appropriate dose of vitamin C has a diagnostic and therapeutic role.
