Since Albert Szent-Györgyi discovered it and it became used in treating scurvy, vitamin C has attracted interest in many studies due to its unique properties. It is an important cofactor in the synthesis of collagen and hormones, and it is involved in immunity, iron absorption, and processes requiring antioxidants. Thus, this review aims to emphasize the importance and usefulness of vitamin C in improving quality of life and preventing various diseases (e.g., chronic diseases, cardiovascular diseases, cancer) but also for its use in treatments against infections, neurodegenerative diseases, and cancer. Although the studies presented provide essential information about the properties of VIC and its beneficial effect on health, some studies contradict these theories. In this respect, further studies on larger samples and over a longer period are needed to demonstrate the therapeutic potential of this nutrient. However, VIC remains a necessary vitamin that should be consumed daily to maintain optimal health and prevent deficiencies that can lead to scurvy and its associated complications.

Aims Methods Results Conclusions To explore the prevalence of vitamin C deficiency, ‘undetectable’ vitamin C status, and scurvy features, in adult hospitalised patients with protein‐energy malnutrition diagnosed using validated malnutrition screening and assessment tools commonly used in clinical practice.This study included adult inpatients from four acute hospitals within a single Australian tertiary health service, over a 3.5‐year period. A medical file review activity retrospectively determined malnutrition risk and diagnosis, via Malnutrition Screening Tool, Malnutrition Universal Screening Tool, Subjective Global Assessment and Global Leadership Initiative on Malnutrition criteria. Prevalence of vitamin C deficiency and scurvy features was examined in adult patients with plasma vitamin C levels <11.4 μmol/L and <5 μmol/L (‘undetectable’), respectively.In the final cohort (n = 364), prevalence of vitamin C deficiency was 30.2%. Malnutrition was present in 76.1% and 79.8% of patients via Subjective Global Assessment (n = 310) and Global Leadership Initiative on Malnutrition criteria (n = 342) respectively. Patients with high nutrition risk and those diagnosed with severe malnutrition had the highest prevalence of vitamin C deficiency, reported as 32.8% for malnutrition detected via Malnutrition Screening Tool (n = 244), 32.9% via Malnutrition Universal Screening Tool (n = 222), 35.8% via Subjective Global Assessment (n = 106), and 34.2% via Global Leadership Initiative on Malnutrition (n = 152). Scurvy features were associated with severe malnutrition in patients with ‘undetectable’ vitamin C status.Severely malnourished adult hospital patients have a high prevalence of vitamin C deficiency, and scurvy features in those with ‘undetectable’ vitamin C status. Leveraging existing malnutrition screening and assessment practices may support early identification of patients with vitamin C deficiency during hospitalisation. [ABSTRACT FROM AUTHOR]

To characterize the nutrients and bioactive compounds in grape berries and to explore the real cause of the "French paradox" phenomenon, we performed metabolomic analysis of 66 grape varieties worldwide using liquid chromatography–tandem mass spectrometry (LC-MS). A nontargeted metabolomics approach detected a total of 4889 metabolite signals. From these, 964 bioactive and nutrient compounds were identified and quantified, including modified flavonoids, medicinal pentacyclic triterpenoids, vitamins, amino acids, lipids, etc. Interestingly, metabolic variations between varieties are not explained by geography or subspecies but can be significantly distinguished by grapes' color, even after excluding flavonoids and anthocyanins. In our analysis, we found that purple grape varieties had the highest levels of key bioactive components such as flavonoids, pentacyclic triterpenes, and polyphenols, which are thought to have a variety of health benefits such as antioxidant, anti-inflammatory, and antitumor properties, when compared to grapes of other colors. In addition, we found higher levels of vitamins in red and pink grapes, possibly explaining their role in preventing anemia and scurvy and protecting the skin. These findings may be a major factor in the greater health benefits of wines made from purple grapes. Our study provides comprehensive metabolic profiling data of grape berries that may contribute to future research on the French paradox. [ABSTRACT FROM AUTHOR]

This paper aims to clarify the nature of understanding in medicine. The first part describes in more detail what it means to understand something and links a type of understanding (i.e., objectual understanding) to explanations. The second part proceeds to investigate what objectual understanding of a disease (i.e., biomedical understanding) requires by considering the case of scurvy from the history of medicine. The main hypothesis is that grasping a mechanistic explanation of a condition is necessary for a biomedical understanding of that condition. The third part of the paper argues that biomedical understanding is necessary, but not sufficient for understanding in a clinical context (i.e., clinical understanding). The hypothesis is that clinical understanding combines biomedical understanding of a disease or pathological condition with understanding illness, which involves some degree of personal understanding of the patient. It is argued that, in many cases, clinical understanding necessitates adopting a particular second-personal stance and using cognitive resources in addition to those involved in biomedical understanding.

Introduction: Scurvy is caused by vitamin C deficiency and manifests with a variety of symptoms including generalized fatigue, apathy, anemia, myalgias, easy bruising, and poor wound healing. It is generally thought of as a disease of the past, especially in developed countries. However, vitamin C deficiency still occurs, especially in patients with lack of access to fruits and vegetables. Other micronutrient deficiencies, including vitamin D deficiency, are also prevalent and can cause a multitude of signs and symptoms including osteomalacia, muscle weakness, and increased risk of many chronic illnesses.Case Report: Here we present a case of vitamin C and D deficiency in a previously healthy 26-year-old man during the coronavirus disease 2019 pandemic in urban America.Conclusion: Severe nutritional deficiencies still exist today. Emergency clinicians should be aware of the signs and symptoms to promptly diagnose and initiate treatment.

Scurvy is often considered a disease of the past and well described in children with neurodevelopment and autistic spectrum disease. Clinicians overlook the diagnosis of scurvy, leading to unwarranted laboratory investigations and, unfortunately, significant delays in diagnosis. This study aims to describe 10 cases of scurvy in a tertiary hospital setup with their clinical profile, comorbidities, radiological, and subsequent disease course in children presenting to the pediatric rheumatology department at Amrita Hospital, Kochi, from 2017 to 2022. Demographic, imaging, and associated comorbid conditions including neuropsychiatric abnormalities were documented. They were all reviewed in 2 weeks for improvement of symptoms. A total of 10 children (3 females) were included in this study. The disease manifested predominantly in early childhood (median age: 5.5 years). All patients had unexplained bone pain and inability to bear weight. The referral diagnosis of 8/10 patients was juvenile idiopathic arthritis. Two patients had autism as a comorbidity. Selective eating habits and food faddism were present in 2/10 children. All patients have made a full functional recovery at review. All patients had imaging findings suggestive of scurvy. Pediatricians and rheumatologists alike must consider scurvy in a child with unexplained bone pain and symptoms masquerading as primary rheumatological diseases. Selective eating habits need to be treated with timely and appropriate psychological rehabilitation and dietary education. Resolution of symptoms and radiographic features with vitamin C supplementation is the strongest evidence for scurvy.

Background Assessment for vitamin C deficiency (VCD) is rarely undertaken in an acute hospital setting in high-income countries. However, with growing interest in VCD in community settings, there is emerging evidence investigating the prevalence and impact of VCD during hospitalization. Objectives In this scoping review, the prevalence of VCD in adult hospitalized patients is explored, patient characteristics are described, and risk factors and clinical outcomes associated with VCD are identified. Methods A systematic scoping review was conducted in accordance with the PRISMA-ScR framework. The Ovid MEDLINE, Ovid Embase, Scopus, CINAHL Plus, Allied and Complementary Medicine Database, and the Cochrane Library databases were searched for interventional, comparative, and case-series studies that met eligibility criteria, including adult hospital inpatients in high-income countries, as defined by the Organization for Economic Co-operation and Development, that reported VCD prevalence using World Health Organization reference standards. These standards define VCD deficiency as plasma or serum vitamin C level <11.4 µmol/L, wholeblood level <17 µmol/L, or leukocytes <57 nmol/108 cells. Results Twenty-three articles were included, representing 22 studies. The cumulative prevalence of VCD was 27.7% (n = 2494; 95% confidence interval [CI], 21.3-34.0). High prevalence of VCD was observed in patients with severe acute illness and poor nutritional status. Scurvy was present in 48% to 62% of patients with VCD assessed in 2 studies (n = 71). Being retired (P  = 0.015) and using excessive amounts of alcohol and tobacco (P  = 0.0003) were independent risk factors for VCD (n = 184). Age was not conclusively associated with VCD (n = 631). Two studies examined nutrition associations (n = 309); results were inconsistent. Clinical outcomes for VCD included increased risk of frailty (adjusted odds ratio, 4.3; 95%CI, 1.33–13.86; P  = 0.015) and cognitive impairment (adjusted odds ratio, 2.93; 95%CI, 1.05–8.19, P  = 0.031) (n = 160). Conclusions VCD is a nutritional challenge facing the healthcare systems of high-income countries. Research focused on early identification and treatment of patients with VCD is warranted.

Scurvy, once prevalent among sailors, is now rare due to improved access to fresh fruits and vegetables yet persists in individuals with poor dietary habits. We report a case of a 35‐year‐old male presenting with month‐long, nonpainful, nonitchy lower extremity lesions. A dermatological examination revealed follicular hyperkeratosis, perifollicular bleeding, corkscrew hairs, bleeding gums, and hemorrhagic purpura. Despite unavailable plasma vitamin C testing, scurvy was diagnosed based on clinical features and dietary history. Treatment with vitamin C resulted in significant improvement within 10 days. Inadequate intake of fruits and vegetables causes vitamin C deficiency, impairing collagen synthesis and leading to typical scurvy symptoms. This case underscores the importance of considering scurvy in patients with compatible symptoms, focusing on clinical diagnosis and treatment response when testing is unavailable. Management includes vitamin C supplementation and dietary changes, emphasizing healthcare providers' role in promoting sufficient fruit and vegetable consumptions to prevent nutritional deficiencies.

Objectives: The osteological paradox recognizes that the presence of lesions is not always directly related with increased mortality. When combined with the clinical, historical, and epidemiological literature on scurvy, survivorship analysis, a form of statistical analysis to assess the relationship between the presence of diseases in the archeological record and survival, helps determine the overall burden of the disease both in terms of morbidity and mortality. This article explores the relationship between scurvy and survivorship in 26 adults from Man Bac, a Neolithic site from northern Vietnam together with prepublished evidence of scurvy in the nonadult population (n = 44). Methods: Diagnosis of scurvy included differential diagnosis combined with the Snoddy, A. M. E., Buckley, H. R., Elliott, G. E., Standen, V. G., Arriaza, B. T., & Halcrow, S. E. (2018). Macroscopic features of scurvy in human skeletal remains: A literature synthesis and diagnostic guide.

Assessing diagnostic certainty for scurvy and rickets in human skeletal remains. American Journal of Biological Anthropology, 181, 637–645 diagnostic certainty approaches. Kaplan–Meier survival curves were produced to assess the relationship between the presence of probable scurvy and age‐at‐death. Results: The prevalence of probable scurvy in adults (35%) was considerably lower than reported for the nonadults (80%). Almost all lesions observed in the adults were in a mixed stage of healing. Kaplan–Meier analysis demonstrated no difference in survivorship between infants and children (<15 years) with or without probable scurvy, whereas a meaningful difference was observed for the adults and adolescents (15+ years). Conclusions: The findings demonstrate that scurvy considerably decreased survivorship to older age categories. The degree of lesion remodeling, however, indicates that scurvy was not necessarily the direct cause of death but contributed to an overall disease burden that was ultimately fatal.

Vitamin C deficiency, colloquially known as scurvy, has become rare in modern times due to the widespread availability of ascorbic acid-rich foods. Despite this, it continues to be a concern in certain at-risk populations. The purpose of this report is to describe the case of a two-year-old girl who initially presented to a pediatric dental clinic with the chief complaint of hypertrophic gingiva and bleeding. Suspecting a systemic cause, the dental team referred the patient to a hematology clinic for further evaluation. Subsequent assessments and laboratory work confirmed a diagnosis of diet-related vitamin C deficiency. Management with supplements led to the resolution of the oral manifestations and normalization of laboratory values. This report details the clinical presentation and pathophysiology of vitamin C deficiency to assist healthcare providers in recognizing signs and symptoms, ensuring timely referral and facilitating appropriate treatment. Additionally, it underscores the importance of pediatric dentists as potentially the first clinicians to encounter such cases and their role in the multidisciplinary management of these pediatric patients.

Aim: We aimed to investigate the frequency of vitamin C deficiency scurvy in the Australian paediatric context, describe cohorts at risk, and identify factors associated with development of symptoms in children with vitamin C deficiency. We also aimed to propose a management guideline for children with features of scurvy. Method: A retrospective study was done at a tertiary paediatric hospital in Australia over a three‐year period, from August 2019 to July 2022. Children from birth to 18 years old, whose vitamin C levels were low (<23 μmol/L), were included. Data extracted from hospital medical records included demographics, weight, co‐morbidities, eating disorder diagnoses, clinical features, investigations and treatment. Descriptive statistics and risk statistics were performed. Results: In a cohort of 887 patients who had their vitamin C levels checked, we identified 272 (31%) who had a vitamin C level <23 μmol/L. Of these, 13 (5%) were symptomatic of vitamin C deficiency and 19 (7%) may have been symptomatic. In patients with vitamin C deficiency, 248 (91%) had comorbidities, neurodevelopmental disorders being most common, and 176 (65%) had restricted eating. When the asymptomatic and symptomatic groups were compared, in the symptomatic group, there was a significantly lower vitamin C level and disordered eating related to autism spectrum disorders was more common. Conclusion: In order to avoid delayed diagnoses and unnecessary investigations, clinicians should be familiar with symptoms of scurvy and perform a dietary assessment, vitamin C assay, and commence empiric vitamin C supplementation where appropriate.

Scurvy is a rare nutritional disorder caused by deficiency of ascorbic acid (vitamin C). It is often under-diagnosed in clinical settings, especially in North America where population statistics are unavailable. However, scurvy is more common than previously thought and appears to be re-emerging in children with developmental delays. Here, we review the pertinent literature and present a case of a previously healthy, 5-year-old, non-verbal boy who presented with multiple, acute, and subacute spontaneous epidural hemorrhages managed by neurosurgical intervention. He remained in hospital for 17 days and was seen in follow-up 3 weeks post-operatively having returned to his neurological baseline. Our case suggests the importance of considering scurvy in patients who have developmental delays and poor nutritional status. [ABSTRACT FROM AUTHOR]

Vitamin C deficiency, otherwise known as scurvy, is one the oldest known diseases. Although its prevalence has substantially diminished, certain populations such as smokers, alcoholics, elderly, and those with malabsorptive syndromes remain at risk. Deficiency presents with perifollicular hemorrhage, corkscrew hairs, and petechiae that can evolve into ecchymoses and purpura. Diagnosis starts with clinical suspicion and is confirmed with plasma and leukocyte ascorbic acid levels. Early suspicion is key. Treatment with vitamin C offers an excellent prognosis and avoids unnecessary workup for differential diagnoses. In our case, a 45-year-old male alcoholic with progressively worsening symptoms was found to have scurvy. Treatment was initiated with vitamin C supplementation, and he had remarkable improvement in his symptoms within weeks. This case demonstrates that scurvy is not a disease of history and must be considered in modern medicine, especially as homelessness with concomitant poor nutrition continues to increase.

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.

Depression is on the rise and medication does not always provide satisfactory relief. This raises the question of a treatment gap that has not yet been (sufficiently) addressed. Inflammation and oxidative stress play an important pathophysiological role, which also leads to a deficiency of antioxidants such as vitamin C. This perspective mini-review reflects the results of a PubMed search combining the search terms depression with inflammation, oxidative stress and vitamin C. Vitamin C is an important antioxidant and co-factor for many neuronal metabolic and epigenetic pathways, and a deficiency is associated with depression and cognitive disorders. Inadequate vitamin C blood levels that do not yet result in somatic symptoms may induce neuropsychiatric scurvy, which is associated with increased neuroinflammation and characterized by depression and cognitive impairment. Experimental studies show that vitamin C has multifactorial effects on metabolic pathways relevant to depression. Treatment of vitamin C deficiency, which is more common than appreciated, should be considered in the management of depressed patients. Further studies should investigate whether the pharmacological administration of vitamin C has additional effects beyond the correction of deficiency.

A patient with scurvy presented with malnutrition and generalised myalgia, bone pain, petechial rash, ecchymosis, gingival hypertrophy and bleeding, and an inability to walk. Initially, the petechial rash, arthralgia and bone pain posed a diagnostic challenge, with differential diagnoses including IgA vasculitis (Henoch–Schönlein purpura, HSP) and leukaemia. However, the rash was not typical of HSP, and there were no pathological blood smear findings. Vitamin C levels in the plasma were prioritised before conducting further investigations, including bone marrow aspiration and skin biopsy. Laboratory and radiological findings confirmed undetectable vitamin C levels in the plasma, and other results were compatible with scurvy and malnutrition. Notably, the erythrocyte sedimentation rate was elevated. The cause of multivitamin deficiency and malnutrition was investigated, and coeliac disease was identified. Scurvy in patients with coeliac disease is very rarely reported. The aim of this article is to draw attention to the importance of assessing and managing the dietary habits of school-age children, and, if necessary, further investigation for coeliac disease, and to highlight that scurvy can mimic HSP.

Background: Scurvy has been a rare condition in the developed world due to the increasing availability of adequate nutrition and easy access to fruits and vegetables. Scurvy is caused by severe vitamin C deficiency and has been historically associated with malnutrition in high-risk populations such as sailors. As it is an uncommon nutritional deficiency, scurvy is seldom suspected and usually under-diagnosed especially in the pediatric population. Case presentation: We report a case of a pediatric patient with a history of autism spectrum disorder presenting with atypical symptoms of scurvy with gait abnormalities, diffuse rash, musculoskeletal deconditioning, and bleeding manifestations. After multiple extensive investigations and a prolonged hospitalization, a detailed dietary analysis revealed a severely restricted diet devoid of fruits and vegetables. Physical examination revealed specific signs of corkscrew hair with peri-follicular hemorrhages, hypertrophic, and bleeding gums with a concurrent low vitamin C level. Treatment with vitamin C supplementation was initiated and he was ambulant within 1 month of discharge. Conclusion: This case highlights the importance of nutrition history for determining micronutrient deficiency in children with special needs. Enhanced physician education and higher index of suspicion regarding nutritional deficiencies will avoid over-investigations and delays for the institution of specific treatment.

The paediatric metaphysis is afflicted by a wide range of pathological processes as it is the most metabolically active and well-vascularised part of the developing skeleton. This review focuses on metaphyseal marrow signal change detected with magnetic resonance imaging, which is most often occult on radiographs. When bilateral, these imaging appearances frequently present a diagnostic quandary. This review assists the radiologist to confidently dismiss physiological signal change and confidently work through the differential diagnosis. This is achieved by illustrating a practical method of classifying signal change into four categories: physiological red marrow, red marrow reconversion, marrow infiltration, and oedema-like marrow signal intensity. In doing so, various pathological entities are reviewed along with imaging pearls and next-step investigations. [ABSTRACT FROM AUTHOR]

The late nineteenth and early twentieth century saw dramatic new developments in climatic medicine, particularly the institutionalisation of thinking about tropical hygiene. There were also more limited efforts to understand how hygiene theories should be applied in a polar environment. Studying the British National Antarctic Expedition (1901–1904), led by Robert Falcon Scott, helps us understand how these practices had both similarities and differences from applications of hygiene in other contexts. The expedition offers unique insights into debates about hygiene, environment, and health because of the important, and well documented, role that medics, naval officers and scientists played in organising logistical arrangements for the journey to Antarctica. In analysing the writings of expedition members and organisers, this paper examines the ways that the universal tools of hygiene theories were applied and developed in a polar environment. Many of the most acute threats seemed to come not from the outside environment but from the explorers' supplies and equipment. There was general agreement on many issues. Yet the expedition's organisers, medics and leadership had numerous arguments about the best way to preserve or restore health. These disagreements were the product of both competing medical theories about the cause of disease and the importance of embodied (and somewhat subjective) observations in establishing the safety of foods, atmospheres and environments in this period.

In this paper we test a long-held assumption regarding Otago, New Zealand, goldfields life and death- that scurvy was a ubiquitous and persistent cause of misery and death among the goldminers. We will also explore a parallel argument that the Chinese market gardeners played a large role in stamping out the disease in the goldfields. Through the interrogation of various archival medical primary sources, we show that scurvy was indeed a terrible scourge in the Otago goldfields, but only during the initial rushes into new regions. We also argue that while Chinese market gardeners undoubtedly contributed to a more nutritious and varied diet for European miners and settlers, scurvy had already markedly reduced in frequency by the time of their arrival in the gold fields. Patient-oriented accounts of scurvy in the gold demonstrate the clinical and functional cost of scurvy in during the initial gold rushes of Otago. Furthermore, individual stories of previously anonymous patients found locked in these archival sources demonstrate the importance of re-humanising the past to understand the biological and social context of these frontier times.

Jacques Cartier (1491-1557) reports, in the account of his second voyage to Canada in 1535-1536, that his crew was afflicted with a "grosse maladie" (scurvy) as well as other diseases, including a case of "grosse verolle" (syphilis), but was cured thanks to herbal teas made with the leaves of a tree called annedda, and in only six days. Until now, research on the annedda episode in the récit du deuxième voyage de Cartier has focused essentially on the nature of the "grosse maladie", on the identification of the plant called annedda, as well as its potential therapeutic virtues. This study aims to show that this episode must be understood in the context of Europe at the turn of the sixteenth century. It will see how the European imagination of the New World, as well as the medical context, notably the severe epidemic of syphilis prevalent at the time in Europe, may have influenced Cartier in the account he made to the king of his voyage.

This research aims to determine the aetiology of porosity and subperiosteal new bone formation on the inferior surface of the pars basilaris. 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. 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. 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. 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). This study highlights the risk of over diagnosing scurvy in past populations. It is difficult to distinguish between physiological (normal) and pathological (abnormal) bone changes in the skeleton of individuals less than one year of age. Future research should focus on the analysis of individuals over 3.5 years of age. [ABSTRACT FROM AUTHOR]

This study aims to determine and discuss the prevalence of non-adult scurvy cases from the early medieval Jaun/Podjuna Valley in southern Austria. 86 non-adult individuals were assessed from three early medieval sites. Morphological characteristics associated with suggestive and probable scurvy were observed macroscopically and under 20–40x magnification. A significant relationship between the prevalence of scurvy and age group was observed. Perinates (46%, 6/13) and children (27.5%, 8/28) showed a high prevalence of skeletal features indicating a diagnosis of scurvy, while no cases of scurvy were observed in adolescents and adults. In this Alpine region, scurvy occurred frequently in infants and children. Seasonal fluctuations of diet are discussed as factors triggering scurvy. This study sheds new light on the prevalence of scurvy in the Alpine region and how the region developed after the fall of the Roman Noricum. It also models ways in which multiple lines of evidence can contribute to the diagnostic process. Poor preservation posed a challenge to identifying probable cases of scurvy. Likewise, non-adult remains are difficult to diagnose due to their developing nature and it is not always possible to distinguish between normal bone growth and pathological growth. Future applications of biomolecular studies will help illustrate changes in diet that may have contributed to vitamin deficiencies. [ABSTRACT FROM AUTHOR]

Scurvy, a rare disease resulting from vitamin C deficiency, can occur in individuals with restrictive eating disorders like anorexia nervosa (AN), leading to severe health complications. This review explores the complex relationship between scurvy and AN, highlighting the overlapping symptoms and challenges in diagnosis and treatment. Vitamin C is essential for collagen synthesis, immune function, and neurotransmitter production, and its deficiency manifests as fatigue, gingival bleeding, joint pain, and perifollicular hemorrhages. AN exacerbates these symptoms through extreme food restriction, causing severe nutritional deficiencies. Analyzing nine case reports, this review reveals that patients with co-occurring AN and scurvy often present with gastrointestinal, psychiatric, and dermatological symptoms. Treatment with vitamin C supplementation typically results in rapid symptom improvement. However, the malnutrition inherent in AN complicates the clinical picture, making timely diagnosis and intervention crucial. This review underscores the importance of a comprehensive, multidisciplinary approach to managing these conditions, emphasizing the need for early recognition and treatment to prevent severe complications. Future research should include a more diverse patient population to enhance understanding of the interplay between AN and scurvy, aiming to improve patient outcomes through tailored treatment strategies.

Abstract 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. Case presentation 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. Conclusion 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.

The article presents a case study of a 6-year-old child diagnosed with scurvy, evidenced by oral manifestations such as gingival overgrowth and palatal ecchymosis. Topics discussed include the patient's medical history, the role of vitamin C deficiency in the condition, and the effective treatment regimen involving vitamin C supplementation that led to a significant improvement in the child's symptoms.

The article describes trends in pediatric scurvy hospitalizations from 2006 to 2021 using the Pediatric Health Information System (PHIS) database. Topics discussed include increase in scurvy hospitalizations after 2017, median length of stay and median cost of admission, and possible factors for the rise in hospitalizations for pediatric scurvy.

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. [ABSTRACT FROM AUTHOR]

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. [ABSTRACT FROM AUTHOR]
