Involvement of the inconstant bursa of the fifth metatarsophalangeal joint in psoriatic arthritis: a clinical and ultrasonographic study.

Objective: To evaluate the involvement of the bursa located next to the head of the 5th metatarsal bone in patients with psoriatic arthritis (PsA) in comparison with the other seronegative spondyloarthritis (SpA).

Methods: All patients with PsA seen during a period of 24 months were enrolled. The control group included healthy subjects and patients with the other SpA.

The evolution of adult-onset Still disease: an observational and comparative study in a cohort of 76 Italian patients.

Objectives: Adult-onset Still's disease (AOSD) is a potentially crippling or life-threatening rare disease that may be self-limited, intermittent, and chronic. Clinical predictors of outcome are still lacking, as is information on the rate of progress of its chronic course. The main objective is to identify factors that improve our ability to predict the course of AOSD, and factors associated with the rate of progress of its chronic course.

Clinical and radiologic evolution of synovitis, acne, pustulosis, hyperostosis, and osteitis syndrome: a single center study of a cohort of 71 subjects.

Objective: To assess the basic features and outcomes of synovitis, acne, pustulosis, hyperostosis, and osteitis (SAPHO) syndrome.

Methods: We identified all patients seen in our unit between 1990 and 2008 diagnosed according to the proposed inclusion criteria with SAPHO syndrome, who had a followup of at least 2 years.

Results: Seventy-one patients (48 women, 23 men) with SAPHO syndrome were identified.

The role of conventional radiography and scintigraphy in the third millennium.

Imaging represents a cornerstone for diagnosing and monitoring rheumatic diseases. In the last few years, with the availability of highly effective therapies, demand for the technical performance of imaging has increased exponentially, leading to rapid development of new technologies such as magnetic resonance imaging (MRI) and ultrasound (US). In both clinical practice and clinical trials, there is a need for tools that are sensitive to change and to therapy response, which are able to depict inflammatory changes early, before irreversible joint damage has occurred.

[Transient regional osteoporosis].

Transient osteoporosis of the hip and regional migratory osteoporosis are uncommon and probably underdiagnosed bone diseases characterized by pain and functional limitation mainly affecting weight-bearing joints of the lower limbs. These conditions are usually self-limiting and symptoms tend to abate within a few months without sequelae. Routine laboratory investigations are unremarkable.

Renal infarction: an uncommon mimic presenting with flank pain.

A 39-year-old woman arrived to the emergency department complaining of a constant, progressive, left flank pain, with no beneficial effect from spasmolytic and nonsteroidal antiinflammatory drugs. Two years before, she suffered another episode of right flank pain and stranguria, but instrumental examinations (ultrasonography, urography) remained negative. Besides a mild tenderness in the left flank, physical examination was normal.

Rheumatoid arthritis: sequences.

Objective: Rheumatoid arthritis (RA) is an autoimmune disorder of unknown etiology characterized by symmetric, erosive synovitis and sometimes multisystem involvement. It affects 1% of the adult population and exhibits a chronic fluctuating course which may result in progressive joint destruction, deformity, disability and premature death. We review the literature data relative to the peculiar pathologic features of the disease shown by diagnostic imaging techniques.

[Periodontal disease in patients with HIV infection. Radiographic study].

A painful and rapidly progressive form of periodontitis--involving both soft tissue and bone, with gingival bleeding and loss of teeth--was observed in HIV-patients in the mid-80's. Today, there are few reports regarding the real incidence of periodontitis in HIV populations: however, it seems not as high as first supposed on discovering the disease, and bacterial plaque is moderate, compared with "conventional" periodontitis. Since there are few radiologic studies, the Authors report on the clinical-radiographic patterns of periodontitis in 20 HIV patients, compared to 20 normal controls.

[Radiographic manifestations in teeth and jaws in chronic kidney insufficiency].

Forty-five patients affected with chronic renal failure (29 men and 16 women; mean age: 47.8 years), treated with hemodialysis for 4 to 245 months (mean: 66.9 months) were examined with panoramic and skeletal radiographs-the latter of the skull, hands, shoulders and clavicles, pelvis and spine.

[Diagnostic imaging of osteoid osteoma].

Conventional radiography, bone scintigraphy and Computed Tomography (CT) are the most useful tools to identify osteoid osteomas. We examined 26 patients (14 men and 12 women) with osteoid osteoma in different skeletal sites (13 femora, 3 tibiae, 3 hands, 2 peroneal bones, 2 humera, 2 spines and 1 talus) and compared the diagnostic yield of the above techniques. The fundamental radiographic findings in this benign bone lesion are the presence of a "nidus", with or without calcifications, perilesional sclerosis and periosteal new bone formation.

Colon involvement in systemic sclerosis: clinical-radiological correlations.

About one third of all patients with systemic sclerosis (SS) presents colon abnormalities, although these may be underestimated because they frequently remain asymptomatic for a long time. Thirty-five patients (33 women and 2 men; mean age 56.5 years; mean disease duration 11.

[Monoarthritis].

By definition, monoarticular arthritis means one-joint involvement, even though, in fact, such a condition is often an oligoarthritis because as many as two or three separate joints will be involved. Arthritis is often limited and may regress, so that it is frequently misdiagnosed. Sometimes, a monoarticular condition may be a polyarthritis onset (i.

Association between diffuse idiopathic skeletal hyperostosis and multiple myeloma.

Objective: To determine whether an association exists between multiple myeloma and diffuse idiopathic skeletal hyperostosis (DISH).

Design And Patients: Radiologic studies were performed over a 26-month period in a series of 97 consecutive patients with multiple myeloma (56 male and 41 female, aged 42-91 years).

Results: Both myelomatous bone lesions and hyperostosis similar to DISH were found in these patients.

[Skeletal changes in the kidney transplant patient].

The skeletal status was investigated with noninvasive diagnostic procedures in 44 renal transplant patients (mean time since intervention: 5 to 195 months) treated with steroid and azathioprine (21 cases) or with steroid, azathioprine and cyclosporine (23 cases). 38.6% of the patients had reduced renal function (creatininemia: 1.

Platyspondyly in treated beta-thalassemia.

Flattening of the vertebral bodies with a platyspondyly appearance is described in 14 patients selected for evaluation of short stature from 106 patients affected by thalassemia major, who received an intensive transfusion regimen combined with continuous chelation therapy. The vertebral body height/width ratio was decreased at the level of all the investigated tracts, namely, cervical and/or dorsal and/or lumbar. The flattening of the vertebral bodies may be due to suppression of intramedullary hematopoiesis by a high transfusion regimen.

[Anomalies of the masticatory apparatus in beta-thalassemia. The present status after transfusion and iron-chelating therapy].

Fifty-four homozygous beta-thalassemic patients (26 men and 28 women) aged 7 to 24 years, who had been treated with high transfusion regimen (Hb levels = 9-10 g/dl) and chelation therapy (desferrioxamine, 35-50 mg/kg), underwent clinical and radiographic investigations. This study was aimed at assessing the clinical and radiographic changes in the stomatognathic system (teeth, mandible and maxilla, occlusion relationship and dental bases). All patients underwent orthopantomography and teleradiography of the skull, in the lateral view.

[The evolutionary effects of therapy on the skeletal lesions in beta-thalassemia].

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.

Continuing loss of vertebral mineral density in renal transplant recipients.

This cross-sectional study examined bone abnormalities by digital radiography, bone densitometry and biochemical tests in 44 clinically asymptomatic renal transplant recipients 6-195 months after renal transplantation. Abnormal radiographs were obtained in 40 of the 44 patients. Dual-energy X-ray absorptiometry (DXA) performed at the lumbar spine (L2-L4)/showed a negative Z score in all patients, ranging from -1 to -1.

[Cephalometry and digital radiography. Technical note].

Conventional and digital lateral teleradiographs of the skull were performed on 6 consecutive patients (3 men and 3 women). The study was aimed at comparing the diagnostic capabilities of the two imaging techniques to measure points and angles, as derived from different cephalometric analyses (see text for details). These variables were analyzed by three different operators: for both techniques, 18 cephalometric tracings were made, including a total of 414 points and 36 angles.

[The temporo-mandibular joint in pathologic conditions: rheumatoid arthritis and seronegative spondyloarthritis].

Pain and dysfunction of the temporomandibular joint (TMJ) are major clinical problems, especially in arthritides and allied conditions. In the last 10 years, such new imaging methods as arthrography, CT and MRI have been developed, but many problems are still to be solved. This study was aimed at reporting the radiographic patterns of lesions in TMJ rheumatoid arthritis and seronegative spondyloarthropathies and at investigating the role of conventional radiology in the assessment of these disorders.

[The hand in hematologic diseases].

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.
