Orthopaedic Manifestations of Scurvy in an Otherwise Healthy Child from a Low Opportunity Index Neighborhood: A Case Report.

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 in A Malnourished Child: Atypical Imaging Findings.

Scurvy, a disease caused by a severe lack of vitamin C in the diet, is most often associated with 17th-century sailors. Its 21st-century manifestation is a disease of the poor, sick, and those living in remote rural neighborhoods in which fresh, nutritious food is hard to come by. It is caused by a deficiency of Vitamin C and is rare in the United States. We describe the radiographic and MRI findings of a case of scurvy in a child with Noonan syndrome who is a "picky eater". MRI is rarely performed in scurvy as its radiographic findings are generally well known and sufficient for a diagnosis. However, due to the rarity of the disease in the US, MRI features of scurvy have been described in only a few case reports, to date. The rarity of this disease also causes scurvy to be kept lower, if at all in the differential diagnosis list.

Modern Day Scurvy in Pediatric Orthopaedics: A Forgotten Illness.

INTRODUCTION: Scurvy, or vitamin C deficiency, is rare. The goal of this study is to highlight the common risk factors and identify the orthopaedic presentation of scurvy in children. METHODS: A retrospective chart and radiograph review was performed of all patients consulted to the pediatric orthopaedic service from 2010 to 2019 who ultimately had the diagnosis of scurvy confirmed by an abnormally low serum vitamin C level. Data extracted included: patient age, sex, neurological conditions, prematurity, psychiatric conditions, dietary abnormalities, bone pain, arthritis, limb swelling, inability to walk, skin changes, child abuse evaluations, radiographic findings, additional vitamin deficiencies, lab studies, additional tests, response to treatment. Descriptive statistics were performed. RESULTS: Nine patients (7 males, 2 females) with scurvy were studied. The average age was 7 years (range 3 to 13 y). The average body mass index was 21.4 (range, 14 to 30). Five had autism, 2 had a neurological disorder. Two had been born premature. Two had a psychiatric disorder. Seven had an abnormal diet. One presented with bone pain. Four presented with limb swelling. Seven had unilateral and 2 had bilateral leg symptoms. Five presented with inability to walk. Six demonstrated skin changes with ecchymosis or petechiae. Three presented with gingival bleeding. Radiographic findings included subperiosteal hematoma in 2, ring epiphysis in 3, Pelkan spurs in 1, metaphyseal white lines (Frankel sign) in 6, and a metaphyseal zone of rarefaction (Trummerfeld zone) in 3. Seven had additional vitamin deficiencies including: A, B1, B6, B9, D, E, K, iron and zinc. Four had a bone marrow biopsy and 1 had lumbar puncture. All were anemic. The average erythrocyte sedimentation rate was 25.7 (range 6 to 35) and C-reactive protein was 1.5 (range 0.55 to 5.64). Six had a computed tomography, 3 had a magnetic resonance imaging. After treatment with vitamin C lasting 3.4 months (range, 2 wk to 7 mo), all symptoms gradually resolved, including leg pain and swelling. All children began to walk. CONCLUSION: The pediatric orthopaedic surgeon should have an increased awareness about the diagnosis of scurvy when consulted on a child with bone pain or inability to walk. The most common orthopaedic presentation was the refusal to bear weight, the most common radiographic finding was the metaphyseal line of increased density (Frankel sign) and treatment with vitamin c supplementation was excellent in all cases.

Vitamin C deficiency mimicking inflammatory bone disease of the hand.

BACKGROUND: Severe vitamin C deficiency, or scurvy, encompasses a syndrome of multisystem abnormalities due to defective collagen synthesis and antioxidative functions. Among the more common presentations is a combination of oral or subcutaneous hemorrhage with lower extremity pain, the latter often exhibiting inflammatory bone changes on magnetic resonance imaging (MRI). CASE PRESENTATION: A 12-year-old male with anorexia nervosa presented with asymmetric painful swelling of multiple fingers of both hands. Imaging demonstrated soft tissue and bone marrow edema of several phalanges, without arthritis, concerning for an inflammatory process. Extensive imaging and laboratory evaluations were largely unrevealing, with the exception of a severely low vitamin C level and a moderately low vitamin D level. A diagnosis of scurvy was made and supplementation was initiated. Within 3 weeks of treatment, serum levels of both vitamins normalized and the digital abnormalities resolved on physical exam. CONCLUSIONS: This represents the first description of scurvy manifesting with bone and soft tissue changes limited to the hands. There must be a high index of suspicion for scurvy in children with restricted dietary intake or malabsorption who have bone pain, irrespective of location of the lesions.

Childhood Scurvy: A Nearly Extinct Disease Posing a New Diagnostic Challenge, a Case Report.

Scurvy is seldom encountered in modern day clinical practice. Children can present with nonspecific features which can mimic several other common conditions. We describe here a four-year-old child who presented with severe pain and weakness of bilateral lower limbs and found to be severely malnourished. The diagnosis of scurvy was suspected in the context of underlying malnutrition after excluding other ominous pathologies. Pathognomic radiological changes clinched the diagnosis, and the best supportive evidence was the dramatic response to vitamin C supplementation.

Scurvy Findings in a Child with Jacobsen Syndrome: A Case Report.

CASE: We describe the first reported case of scurvy developing secondary to behavioral traits of Jacobsen syndrome. The diagnosis of scurvy was significantly delayed because bleeding symptoms were initially attributed to baseline thrombocytopenia and platelet dysfunction associated with Jacobsen syndrome and patient's medication. Following vitamin C supplementation, signs and symptoms of the patient's disease quickly resolved. CONCLUSIONS: We aim to reinforce the need to consider nutritional deficiencies in patients with complex medical histories and behavioral issues, especially when presenting with new complaints.

Scurvy Due to Selective Diet in a Seemingly Healthy 4-Year-Old Boy.

Scurvy is a rare disease in developed nations. In the field of pediatrics, it primarily is seen in children with developmental and behavioral issues, malabsorptive processes, or diseases involving dysphagia. We present the case of an otherwise developmentally appropriate 4-year-old boy who developed scurvy after gradual self-restriction of his diet. He initially presented with a limp and a rash and was subsequently found to have anemia and hematuria. A serum vitamin C level was undetectable, and after review of the MRI of his lower extremities, the clinical findings supported a diagnosis of scurvy. Although scurvy is rare in developed nations, this diagnosis should be considered in a patient with the clinical constellation of lower-extremity pain or arthralgias, a nonblanching rash, easy bleeding or bruising, fatigue, and anemia. This case highlights the importance of carefully assessing a child's dietary and developmental status at well-child visits, which can help avoid a more invasive workup.

Scurvy: an unusual complication of paediatric cancer treatment.

Scurvy is a disease that is rarely encountered in modern medicine. A condition that was classically associated with sailors, its incidence has decreased dramatically since the discovery of its association with vitamin C deficiency. We present the case of a 2-year-old boy, whose treatment for neuroblastoma was complicated by gastrointestinal disease, which necessitated enteral feeding. While still undergoing treatment, he started to complain about increasing pain in his lower limbs, which appeared to be markedly tender on palpation. Radiographic findings suggested a diagnosis of scurvy, which was subsequently confirmed on serum biochemistry. This was an unexpected finding, as the child had been receiving adequate vitamin C in his enteral feeds. However, his absorption had become severely impaired due to pseudomembranous gastritis and enteritis, leading to his deficient state. He significantly improved after intravenous ascorbic acid replacement and demonstrated a full recovery, both clinically and radiologically. This case highlights the importance of considering scurvy in the differential diagnosis for at-risk patients. Early recognition can facilitate the simple treatment of this potentially serious condition.

Scurvy: a rare case in an adult.

A 69-year-old man presented with unilateral calf pain, swelling, and erythematous rash. He was initially treated with antibiotics for suspected cellulitis. A venous duplex ultrasound, performed to exclude deep venous thrombosis, revealed multiple heterogeneous hypoechoic foci of unknown etiology throughout the calf musculature. His condition did not improve with antibiotics, instead progressing to a necrotic ulcer along the medial malleolus. Clinical suspicion of vascular insufficiency or vasculitis prompted an extensive imaging work-up. CT and MRI revealed the intramuscular abnormalities observed on previous ultrasound represented foci of intramuscular hemorrhage. Marrow signal abnormality was also noted in the proximal tibia. A punch biopsy of the skin rash ultimately demonstrated distorted hair follicles with perifollicular inflammation and hemorrhage concerning for scurvy. The diagnosis was confirmed by low vitamin C levels and dietary history. A resurgence of scurvy has occurred in the pediatric population in recent years. However, this diagnosis remains uncommon in adults, with limited reports of the potential advanced imaging findings in the current literature.

Modern American scurvy - experience with vitamin C deficiency at a large children's hospital.

BACKGROUND: Until recently scurvy has been viewed in developed countries as a disease of the past. More recently there have been reports of case series of children with scurvy who have had a delayed diagnosis after an extensive diagnostic workup that included imaging. Most of these children have had underlying neurologic conditions such as autism. OBJECTIVE: To review the medical records of children diagnosed with vitamin C (ascorbic acid) deficiency based on serum ascorbic acid levels at a large pediatric health care system, to determine imaging findings and utility of imaging in management, and to identify at-risk pediatric populations. MATERIALS AND METHODS: We retrospectively identified cases of vitamin C deficiency in children tested for serum ascorbic acid levels during the last 5 years. We used the criteria of normal ascorbic acid >23 µmol/L and included children with ascorbic acid levels <23 µmol/L. We evaluated their clinical history, underlying medical condition, imaging studies obtained and imaging findings. RESULTS: We identified 32 children with vitamin C deficiency. All of these children had underlying medical conditions, most commonly iron overload from multiple transfusions related to sickle cell anemia or thalassemia (20), neurologic disorders (4) and bone marrow transplant/chemotherapy (3). No cases of scurvy from dietary deficiency in otherwise normal children were identified. All except two children had multiple imaging studies, primarily related to their underlying conditions. Three of these children had extensive imaging workups related to diffuse musculoskeletal pain. Imaging findings included ill-defined sclerotic and lucent metaphyseal bands (mainly at the knee) on radiography and MRI studies that showed diffuse increased T2-weighted signal in the bilateral lower-extremity long-bone metaphyses, periosteal reaction and adjacent soft-tissue edema. CONCLUSION: Vitamin C deficiency is not uncommon in large pediatric health care facilities, and it is frequently missed on clinical evaluation and diagnostic imaging. At-risk populations include those with iron overload, neurologic conditions and history of chemotherapy. Scurvy related to dietary deficiency in otherwise normal children was not encountered. When characteristic MRI findings are seen, particularly in children with a predisposing condition for vitamin C deficiency, scurvy should be considered and a serum ascorbic acid level checked to potentially confirm a diagnosis prior to further invasive tests.

Diffuse nonscarring alopecia of scalp: an indicator of early infantile scurvy?

An infant with diffuse nonscarring alopecia of scalp and radiologic features of scurvy responded dramatically to oral vitamin C therapy. The characteristic cutaneous manifestations of scurvy are usually not seen in infancy. The manifestations of initial stage of scurvy that are not related to collagen synthesis, as in the present case, should alert to the possibility of this potentially fatal condition.
