Up to the mid-1960s, beta-thalassemia was treated with blood transfusions as frequent as needed to keep symptoms under control and to prevent transfusional hemosiderosis. In the following years, high transfusion regimens and iron chelation therapy with desferrioxamine were used. Because of these different treatment modalities, skeletal findings in thalassemia have markedly changed. In the past, thalassemic patients treated with a low transfusion regimen and without chelation therapy developed osteopenia--with widened medullary spaces, cortical
thinning
and trabecular atrophy--secondary to chronic expansion of red marrow, due to increased erythropoietin response to chronic anemic hypoxia. Typical radiographic patterns in the skull included widened diploic space, atrophic-especially outer--tables and, in some patients, the "hair-on-end" pattern. As for the face, obliteration of the paranasal sinuses and the typical "rodent facies" were observed. In the ribs, bulbous expansion of the posterior and anterior segments and the "rib within a rib" patterns were observed. As for the spine, coarse trabecular arrangement was seen. The "cobweb" pattern was seen in the pelvis and finally the lack of the normal concave outline was observed in the long bones. In the patients treated with high transfusion regimens and iron chelation therapy over the last 30 years, both skull anomalies and disfigurement are less frequent. The skull is almost normal, with the exception of osteopenia and thickened diploic space in the frontal bone only; the paranasal sinuses are usually not obliterated. The hands and rib are normal, just like long bones, pelvis, scapulae and vertebral bodies. Nevertheless, in some adequately treated patients new skeletal features have been recently observed in the long bones, which are similar to those occurring in rickets and/or
scurvy
, and in the vertebral bodies, resembling platyspondylia. These abnormal features might be caused by several factors--i.e., marrow expansion, transfusion regimens, direct/indirect effects of desferrioxamine, iron load, endocrine abnormalities, deficiency of some minerals and finally dysvitaminoses. Nevertheless, osteopenia remains the main negative factor of thalassemia.

Radiography of the hand often reflects the picture of generalized diseases, affecting both the muscolo-skeletal system and the others. Some of the most common hematologic disorders may be detected in roentgenograms of the hand, especially in the anemias, but also in plasma cell dyscrasias and proliferative malignant diseases (i.e., lymphomas and leukemias). On the basis of their experience, the authors have reviewed and discussed the radiographic "pattern" of the hand in several hematologic conditions (i.e., anemias; thalassemias; sickle-cell disease; lymphomas; multiple myeloma; etc.), and their pathogenesis. Radiographies of both the hands, in antero-posterior view, were performed using Kodak-Min R film; xeroradiography was performed--in the same projection--using Rank Xerox plate, developed always in "positive mode" in 125 Rank Xerox System, conditioned with contrast "D", for emphasizing osseous details. Recently, digital radiography--employing PCR system--has substituted xeroradiography, because of its well-known properties and diagnostic advantages: in this manner, changes in bone and soft tissue are demonstrated on the same image, with augmentation of diagnostic information, with reduced dose to patient. In our series, hand is always involved (100% of cases) in thalassemias: lesions are characterized by diffuse osteopenia (washed out melted appearance), with widening of bone marrow space, diaphyseal convex aspect of the long bones,
thinning
of the cortex, and cyst-like changes (rain drops). Lesions disappear completely after the hypertransfusion regimen (HTR). Following chelation therapy, lesions of the wrist and hand are similar to those described in rickets and/or
scurvy
. Sometimes, the hand is characteristically affected in sickle-cell disease--particularly in the so called hand-foot syndrome--as "cone-deformity". In multiple myeloma incidence of hand involvement is 2.9%: lesions reflect general abnormalities observed in other skeletal sites, and they consist in multiple well-circumscribed lytic lesions. In amyloidosis, poorly defined radiolucent areas may be discovered. In non-Hodgkin lymphoma, incidence of hand involvement is less frequent, approximately 0.2%: the radiographic pattern is aspecific (mottled lytic lesions), sometimes simulating multiple myeloma and/or leukemias. In hemophilia, swelling of soft tissues, around the interphalangeal joint, related to intra-articular and/or per-articular hematoma, is observed. The other conditions reflect general radiographic features of anemias, which are of three main types: 1. the over active marrow (i.e., polycythemia); 2. the infarction of bone (i.e., sickle-cell disease); 3. non-specific findings, resulting from chronic illness (delays of maturation; dwarfism; osteopenia; tendency to infection).

We treated a chronic alcoholic patient who showed all the symptoms of
scurvy
(petechiae, greyish skin colour, areas of
thinning
hair on the head, gingivitis, elevated liver enzyme levels, hyponatraemia, hypalbuminaemia and hypothyroidism) at admission. Even today, alcoholics and chronically ill people in particular can develop symptoms of diet-related vitamin C deficiency.

Introduction. Nutritional deficiencies are rarely reported in developed countries. We report a child of Pakistani origin brought up in Dubai who developed skeletal manifestations of
scurvy
due to peculiar dietary habits. Case Presentation. A 4.5 year old boy presented with pain and swelling of multiple joints for three months and inability to walk for two months. Dietary history was significant for exclusive meat intake for the preceding two years. On examination the child's height and weight were below the 5th percentile for his age. He was pale and tachycardic. There was significant swelling and tenderness over the wrist, knee and ankle joints, along with painful restriction of motion. Basic blood workup was unremarkable except for anemia. However, X-rays showed delayed bone age, severe osteopenia of the long bones, epiphyseal separation, cortical
thinning
and dense zone of provisional calcification, suggesting a radiological diagnosis of
scurvy
. The child was started on vitamin C replacement therapy. Over the following two months, the pain and swelling substantially reduced and the child became able to walk. Repeat X-rays showed improvement in the bony abnormalities. Conclusion. Although
scurvy
is not a very commonly encountered entity in the modern era, inappropriate dietary intake can lead to skeletal abnormalities which may be confused with rickets. A high index of suspicion is thus required for prompt diagnosis of
scurvy
in patients with bone and joint symptoms.

Scurvy
is a rare disease in developed countries. Risk groups include children with restricted diets, mainly patients who are autistic or have cerebral palsy. Furthermore, consumption of plant-based beverages has increased in recent years, especially in developed countries. When plant-based beverages are the exclusive diet in the first year of life and not consumed as a supplement to formula or breastfeeding, it can result in severe nutritional problems. We report a case of
scurvy
after exclusive intake of almond beverages and almond flour from 2.5 to 11.0 months of life. The patient was referred for pathologic fractures of the femur, irritability, and failure to thrive. He had typical radiologic signs of
scurvy
, such as osteopenia, cortical
thinning
, Wimberger ring, Frankel line, fracture, and periosteal reaction. Moreover, his plasmatic vitamin C level was very low. The child was diagnosed with
scurvy
and was started on vitamin C replacement therapy at a dose of 300 mg per day. Over the following 3 months, his general condition, the pain in the legs, and the radiologic features improved; the plasmatic vitamin C level was normalized; and the child started walking. In summary, this case demonstrates that
scurvy
is a new and severe complication of improper use of almond drinks in the first year of life. Manufacturers should indicate that these beverages are inappropriate for infants who consume a vitamin C-deficient diet.
