ABSTRACT
INTRODUCTION: In the era of modern medicine, scurvy has been thought of as a rare disease of ancient times because of improved emphasis on diet and nutrition; however, isolated case reports are plentiful. This investigation presents a comprehensive review of scurvy, including an analysis on its rising incidence, with specific focus on its orthopaedic manifestations and commonly associated diagnoses. METHODS: This comprehensive review includes a retrospective analysis of 19,413,465 pediatric patients in the National Inpatient Sample database from 2016 through 2020. Patients with scurvy were identified by the ICD-10 code, and an estimated incidence of scurvy in the inpatient pediatric population was calculated. Concurrent diagnoses, musculoskeletal reports, and demographic variables were collected from patient records. Comparisons were made using analysis of variance or chi-square with Kendall tau, where appropriate. RESULTS: The incidence of scurvy increased over the study period, from 8.2 per 100,000 in 2016 to 26.7 per 100,000 in 2020. Patients with scurvy were more likely to be younger (P < 0.001), male (P = 0.010), in the lowest income quartile (P = 0.013), and obese (P < 0.001). A majority (64.2%) had a concomitant diagnosis of autism spectrum disorder. Common presenting musculoskeletal reports included difficulty walking, knee pain, and lower limb deformity. Burden of disease of scurvy was markedly greater than that of the average inpatient population, with these patients experiencing greater total charges and longer hospital stays. CONCLUSION: Clinicians should be aware of the increasing incidence of scurvy in modern medicine. In cases of vague musculoskeletal reports without clear etiology, a diagnosis of scurvy should be considered, particularly if risk factors are present. TRIAL REGISTRATION NUMBER: NA.

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.

OBJECTIVES: This research aims to determine the aetiology of porosity and subperiosteal new bone formation on the inferior surface of the pars basilaris. MATERIALS: 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). SIGNIFICANCE: This study highlights the risk of over diagnosing scurvy in past populations. LIMITATIONS: It is difficult to distinguish between physiological (normal) and pathological (abnormal) bone changes in the skeleton of individuals less than one year of age. SUGGESTIONS FOR FURTHER RESEARCH: Future research should focus on the analysis of individuals over 3.5 years of age.

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.

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.

Scurvy is a disease caused by vitamin C deficiency. Although rare, in recent years, the number of scurvy cases in children with eating disorders has increased. Its manifestations are varied because vitamin C is a cofactor in numerous processes, such as collagen synthesis. The typical skin manifestations include petechiae, bruising, and hyperkeratosis. Mucosal involvement manifests as gingivitis with hypertrophy, bleeding, and loss of teeth. The diagnosis is based on clinical findings and may be confirmed by measuring plasma vitamin C levels. The objective of this study was to describe a cohort of patients diagnosed with scurvy in recent years, its clinical manifestations, and findings in relation to their eating behavior and neurodevelopmental disorders.
El escorbuto es una enfermedad producida por déficit de vitamina C. Aunque es poco frecuente, en los últimos años observamos un incremento de casos en niños con trastornos de la conducta alimentaria. Sus manifestaciones son variadas, ya que esta vitamina actúa como cofactor en numerosos procesos, como la síntesis de colágeno. Las manifestaciones cutáneas características son las petequias, equimosis e hiperqueratosis. El compromiso mucoso se manifiesta como gingivitis con hipertrofia, hemorragias y pérdida de piezas dentarias. El diagnóstico es clínico y puede confirmarse mediante la determinación de la vitamina C plasmática. El objetivo de este trabajo es describir una cohorte de pacientes diagnosticados en los últimos años, manifestaciones clínicas y hallazgos en relación con su conducta alimentaria y trastornos del neurodesarrollo.

OBJECTIVE: This study aims to determine and discuss the prevalence of non-adult scurvy cases from the early medieval Jaun/Podjuna Valley in southern Austria. MATERIALS: 86 non-adult individuals were assessed from three early medieval sites. METHODS: Morphological characteristics associated with suggestive and probable scurvy were observed macroscopically and under 20-40x magnification. RESULTS: 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. CONCLUSIONS: In this Alpine region, scurvy occurred frequently in infants and children. Seasonal fluctuations of diet are discussed as factors triggering scurvy. SIGNIFICANCE: 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. LIMITATIONS: 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. SUGGESTIONS FOR FURTHER RESEARCH: Future applications of biomolecular studies will help illustrate changes in diet that may have contributed to vitamin deficiencies.

BACKGROUND: Scurvy is an uncommon disease in developed countries caused by deficiency of vitamin C. We present a case of scurvy in a 14-year-old male with autism with both novel presentation and imaging findings. This case had the novel presentation of lower limb deep vein thrombosis (DVT) secondary to compression of the external iliac vein from large bilateral iliac wing subperiosteal hematomas. Subperiosteal hematoma is a well-recognised feature of scurvy but large and bilateral pelvic subperiosteal hematoma causing DVT has not previously been described. CASE PRESENTATION: A 14 year old Caucasian male with background of autism and severe dietary restriction presented with lower limb swelling and immobility. He was diagnosed with lower limb DVT. Further investigation revealed an iron deficiency anaemia, and he was found on MRI to have large bilateral subperiosteal iliac hematomata causing compression of the iliac vessels. He improved following treatment with vitamin C replacement and follow-up imaging demonstrated resolution of the DVT and hematoma. CONCLUSION: DVT is rare in children and when diagnosed should prompt investigation as to the underlying cause. This case demonstrates an unusual cause of DVT and as an unusual presentation of paediatric scurvy.

CASE: A 23-month-old otherwise healthy female child from a low opportunity index neighborhood presented with 1 month of lower extremity pain and refusal to bear weight. Radiographic evaluation of bilateral knees revealed lucent metaphyseal bands and a nondisplaced distal femoral metaphyseal corner fracture. A workup identified vitamin C deficiency (scurvy), and the child's symptoms and radiographic abnormalities resolved with vitamin C supplementation. CONCLUSIONS: Scurvy should be considered in children with unexplained musculoskeletal symptoms who may lack access to nutrient-dense foods.

Scurvy is caused by vitamin C deficiency and is often thought of as an ancient malady. However, it still afflicts present-day patients with insufficient nutrition, excessive alcohol consumption and disorders of absorption. Scurvy is traditionally characterised by ecchymosis, petechiae, haemorrhages, poor wound healing, myalgias and arthralgias, but it can also present with non-specific symptoms, including mood changes, fatigue, malaise and dyspnoea. Although scurvy can present with signs of excess bleeding, it does not involve blood clotting. We present a case of concurrent scurvy and pulmonary embolism in which clinical presentation and laboratory findings mimicked a coagulation disorder, resulting in delayed diagnosis and excessive resource expenditure. This case underscores the importance of obtaining an early dietary and substance use history in patients with unexplained haematological symptoms. These crucial components of history-taking can significantly reduce invasive and costly tests, resulting in quicker diagnosis and enhanced patient outcomes.

BACKGROUND: Severe pulmonary hypertension (PH) in childhood is rare and can manifest as a life-threatening episode. We present 2 children with restrictive dietary habits with severe pulmonary hypertension secondary to scurvy and iron deficiency anemia with treatment and outcome. CASE PRESENTATION: The first case is a 2-year-old boy who presented with vomiting, diarrhea, and fever. After rehydration, he had recurrent episodes of hypotension with intermittent abdominal pain. Fluid resuscitation and inotropic medication were given. Then he suddenly collapsed. After 4-min cardiopulmonary resuscitation, his hemodynamic was stabilized. Most of the medical workup was unremarkable except for PH from the echocardiogram with estimated systolic pulmonary artery pressure (PAP) at 67 mmHg. Transient PH was diagnosed, and milrinone was prescribed. Since he had restrictive dietary habits and sclerotic rim at epiphysis in chest films, his vitamin C level was tested and reported low-level result. The second case is a 6-year-old boy with acute dyspnea, a month of low-grade fever, mild cyanosis, and a swollen left knee. Echocardiogram indicated moderate TR with estimated systolic PAP at 56 mmHg (systolic blood pressure 90 mmHg). Milrinone was given. Right cardiac catheterization showed PAP 66/38 (mean 50) mmHg and PVRi 5.7 WU.m2. Other medical conditions causing PH were excluded. With a history of improper dietary intake and clinical suspicion of scurvy, vitamin C was tested and reported undetectable level. Administration of vitamin C in both cases rapidly reversed pulmonary hypertension. CONCLUSION: Pediatric PH related to vitamin C deficiency can manifest with a wide range of symptoms, varying from mild and nonspecific to severe life-threatening episodes characterized by pulmonary hypertensive crises. PH associated with scurvy is entirely reversible with appropriate investigation, diagnosis, and treatment. Our report highlights the importance of considering nutritional deficiencies as potential confounding factors in pediatric PH, emphasizing the need for comprehensive evaluation and management of these patients.

OBJECTIVES: Vitamin C deficiency in children commonly presents with musculoskeletal symptoms such as gait disturbance, refusal to bear weight, and bone or joint pain. We aimed to identify features that could facilitate early diagnosis of scurvy and estimate the cost of care for patients with musculoskeletal symptoms related to scurvy. METHODS: We conducted a retrospective chart review of patients at a single site with diagnostic codes for vitamin C deficiency, ascorbic acid deficiency, or scurvy. Medical records were reviewed to identify characteristics including presenting symptoms, medical history, and diagnostic workup. The Pediatric Health Information System was used to estimate diagnostic and hospitalization costs for each patient. RESULTS: We identified 47 patients with a diagnosis of scurvy, 49% of whom had a neurodevelopmental disorder. Sixteen of the 47 had musculoskeletal symptoms and were the focus of the cost analysis. Three of the 16 had moderate or severe malnutrition, and 3 had overweight or obesity. Six patients presented to an emergency department for care, 11 were managed inpatient, and 3 required critical care. Diagnostic workups included MRI, computed tomography, echocardiogram, endoscopy, lumbar puncture, and/or EEG. Across all patients evaluated, the cost of emergency department utilization, imaging studies, diagnostic procedures, and hospitalization totaled $470 144 (median $14 137 per patient). CONCLUSIONS: Children across the BMI spectrum, particularly those with neurodevelopmental disorders, can develop vitamin C deficiency. Increased awareness of scurvy and its signs and symptoms, particularly musculoskeletal manifestations, may reduce severe disease, limit adverse effects related to unnecessary tests/treatments, and facilitate high-value care.

Proptosis is a frequent presenting symptom/sign of many paediatric malignancies. Acute-onset proptosis is an ophthalmic emergency that can endanger vision if not treated promptly. Appropriate treatment must be instituted only after investigating for the underlying aetiology. Here, we report a developmentally delayed boy in middle childhood who presented with recent onset bilateral proptosis. Clinical examination followed by radiological evaluation suggested scurvy to be the underlying cause and vitamin C supplementation led to prompt reversal of proptosis. The relevant literature has been reviewed and presented here to apprise the paediatric oncologists about this rare but easily treatable cause of proptosis.
