Abstract
Children and adolescents with localized scleroderma (LS) are at high risk for extracutaneous-related functional impairment including hemiatrophy, arthropathy, seizures, and vision impairment. Compared with adult-onset LS, pediatric disease has a higher likelihood for poor outcome, with extracutaneous involvement twice as prevalent in linear scleroderma, disease relapses more common, and disease duration more than double. Consensus among pediatric rheumatologists on treating patients at risk for significant morbidity with systemic immunosuppressants has led to major improvements in outcome. This review discusses recent progress in assessment and treatment strategies and in our understanding of key disease pathways.

Abstract
BACKGROUND The distribution of pediatric-onset morphea and site-based likelihood for extracutaneous complications has not been well characterized. OBJECTIVE To characterize the lesional distribution of pediatric-onset morphea and to determine the sites with the highest association of extracutaneous manifestations. METHODS A retrospective cross-sectional study was performed. Using clinical photographs, morphea lesions were mapped onto body diagrams using customized software. RESULTS A total of 823 patients with 2522 lesions were included. Lesions were more frequent on the superior (vs inferior) anterior aspect of the head and extensor (vs flexor) extremities. Linear morphea lesions were more likely on the head and neck, whereas plaque and generalized morphea lesions were more likely on the trunk. Musculoskeletal complications were more likely with lesions on the extensor (vs flexor) extremity (odds ratio [OR], 2.0; 95% confidence interval [CI], 1.2-3.4), whereas neurologic manifestations were more likely with lesions on the anterior (vs posterior) (OR, 2.8; 95% CI, 1.7-4.6) and superior (vs inferior) aspect of the head (OR, 2.3; 95% CI, 1.6-3.4). LIMITATIONS Retrospective nature and the inclusion of only patients with clinical photographs. CONCLUSION The distribution of pediatric-onset morphea is not random and varies with body site and within individual body sites. The risk stratification of extracutaneous manifestations by body site may inform decisions about screening for extracutaneous manifestations, although prospective studies are needed.

Abstract
Recent findings indicate that patients with systemic sclerosis have an increased risk of cardiovascular disease. To determine whether patients with systemic sclerosis or localized scleroderma are at increased risk of cardiovascular disease, a cohort study of the entire Danish population aged ≥ 18 and ≤ 100 years was conducted, followed from 1997 to 2011 by individual-level linkage of nationwide registries. Multivariable adjusted Cox regression models were used to estimate the hazard ratios (HRs) for a composite cardiovascular disease endpoint. A total of 697 patients with localized scleroderma and 1,962 patients with systemic sclerosis were identified and compared with 5,428,380 people in the reference population. In systemic sclerosis, the adjusted HR was 2.22 (95% confidence interval 1.99-2.48). No association was seen between patients with localized scleroderma and cardiovascular disease. In conclusion, systemic sclerosis is a significant cardiovascular disease risk factor, while patients with localized scleroderma are not at increased risk of cardiovascular disease.

Abstract
OBJECTIVES Some authors consider that morphoea and systemic sclerosis (SSc) could be part of the same disease spectrum. The aim of this study was to analyse the prevalence of signs indicative of SSc in a cohort of patients with morphoea. METHODS This is a prospective multi-centre study performed in four French academic dermatology departments: 76 patients with morphoea and 101 age- and sex-matched controls, who underwent complete clinical examination, were enrolled. A systemic search for signs indicative of SSc (e.g. Raynaud's phenomenon, reflux) was performed with the help of a standardised questionnaire. RESULTS There were 58 women and 18 men (ration=3/1) with a median age of 59 years. Mean age at diagnosis was 54 years (extremes, 13-87). 49 subjects had plaque morphoea, 9 had generalised morphoea and 18 had linear morphoea. Mean duration of morphoea was 7.9 years. Signs possibly indicative of SSc were noted in four patients of the control group and in 8 patients with morphoea. This difference was not statistically significant (p=0.129). Further investigations ruled out SSc in all patients. CONCLUSIONS Signs indicative of SSc are statistically not more frequently present in patients with morphoea than in controls and this study does not support the view that those 2 entities are part of a common disease spectrum.

Abstract
Connective tissue diseases (CTDs) are defined as a group of acquired disorders resulting from persistent immuno-mediated inflammation. Several classes of drugs seem to be capable of inducing or exacerbating CTDs. A drug-induced (DI) syndrome is defined as a condition temporally related to continuous drug exposure, which resolves upon drug discontinuation. Among CTDs, lupus erythematosus is the most widely known and investigated DI syndrome. However, in recent years, the association between the onset of other CTDs, such as dermatomyositis (DM) and morphea/systemic sclerosis (SSc) has increased in patients with preceding exposure to particular substances. Herein, we conducted a review of published case reports including DM and morphea/SSc, evaluating the real causality among drugs and these syndromes.

Abstract
BACKGROUND Scleroderma is a chronic connective tissue disease characterized by hardened or scaly skin and widespread abnormalities of the viscera, which is rare in the pediatric age group. OBJECTIVE In this study, we retrospectively reviewed 23 pediatric patients suffering systemic (SSc) and localized (LS) scleroderma. METHODS Twenty-three patients were enrolled and were diagnosed with SSc or LS from March 1993 to September 2009 in the Department of Pediatrics at Mackay Memorial Hospital in Taipei, Taiwan. These diagnoses were based on the criteria of the American College of Rheumatology and the clinical manifestations of hard skin. Data recorded included sex, age-at-onset, age-at-diagnosis, laboratory data, family history, trauma history, treatment, and outcomes. RESULTS Three patients suffered SSc and 20 patients had LS, including 16 girls and 7 boys. Mean age-at-onset was 6.55 +/- 3.28 years old. Antinuclear antibodies were positive in 15 patients. Tests for anti-Scl-70 antibodies were positive in 1 patient with SSc. One boy had en coup de sabre combined with a posterior fossa tumor. Twenty-two patients were treated with D-penicillamine. Oral prednisolone and methotrexate were added, if indicated. One girl with LS developed proteinuria after D-penicillamine treatment. All patients with localized disease ultimately documented a softening of their skin lesions. CONCLUSIONS While scleroderma is rare in children, the prognosis of SSc is poor but better than for adults. The prognosis for LS is usually benign, however, the skin may become progressively indurated and it may not only be a skin disease. No progression from LS to SSc was observed in our study.

Abstract
BACKGROUND Sclerodermas are rare affections which can be located or generalized. Localized form is the most frequent. AIM The purpose of this study was to describe epidemiologic, clinics, biological, immunological, therapeutic, evolutionary characteristics of the localized scleroderma through a personal series and the data of the literature. METHOD We have performed a retrospective study on all patients followed in the department of dermatology of the Hospital Charles Nicole during 14 years period. RESULTS Our study was about 92 cases of localized scleroderma (73 were females and 19 males). The mean age was 35 years (between 2 and 72 years). The majority of localised sclerodermas (66.2% of the cases) appeared before 40 years with a maximum of frequency between 10 and 30 years (41.6%). Only 11.9% of the cases were observed before 10 years. They were 51 cases (55%) of morphea, 35 cases (38%) of scleroderma in bands including 32 linear scleroderma and 3 scleroderma en coup de sabre, 5 cases (5.5%) of generalized morphea and 1 case (0.15%) of deep morphea. Average therapeutic was specified among 63 patients (87%), and the evolution could be appreciated among 45 patients. CONCLUSION The epidemiologic data observed in our series are comparable with those reported in the literature. Therapeutic difficulties and risks of functional after-effects, particular in scleroderma in bands, remain the principal concern for all the authors.

Abstract
The etiology of systemic sclerosis, probably multifactorial, is not yet well defined. Among the many endogenous and exogenous factors probably involved, occupational elements may play an essential role. Here we report a cluster of local scleroderma and systemic sclerosis, which occurred in a small group of typography workers exposed to polyvinyl-acetate glues, containing up to 1% of vinyl-acetate. Vinyl acetate exposure has been associated with acidification of the intracellular environment, which is thought to produce cytotoxic and/or mitogenic responses that are the sentinel pharmacodynamic steps toward cancer. Autoantibody production in systemic sclerosis depends upon intracellular acidification. More studies are needed to clarify the relationship between vinyl acetate exposure and scleroderma.

Abstract
BACKGROUND Most of the available documentation in the literature on ocular involvement in localised scleroderma (LS) are descriptions of single cases in adult patients. This article reports the frequency and specific features of ocular involvement in a large cohort of children with juvenile LS (JLS). METHODS Data from a large, multi-centre, multinational study of children with LS were used to collect and analyse specific information on ocular involvement. RESULTS 24 out of 750 patients (3.2%) revealed a significant ocular involvement. 16 were female and 8 male. 16 patients (66.7%) had scleroderma "en coup de sabre" (ECDS) of the face, 5 (20.8%) had the linear subtype, 2 (8.3%) had generalised morphea (GM) and one (4.2%) had plaque morphea (PM). Of the 24 patients with eye involvement, 10 patients (41.7%) reported adnexa (eyelids and eyelashes) abnormalities, 7 (29.2%) anterior segment inflammation (5 anterior uveitis, 2 episcleritis) and 3 central nervous system-related abnormalities. 4 patients presented single findings such as paralytic strabismus (1), pseudopapilloedema (1) and refractive errors (2). Other extracutaneous manifestations were detected in a significantly higher number of patients with ocular involvement and were mostly neurological. CONCLUSION Ocular abnormalities are not unusual in patients with JLS, especially in the ECDS subtype. They are frequently associated with other internal organ involvement, particularly the central nervous system (CNS). Careful ophthalmic monitoring is recommended for every patient with JLS, but is mandatory in those with skin lesions on the face and/or concomitant CNS involvement.

METHODS A retrospective review of patients diagnosed with en coup de sabre morphea or Parry-Romberg syndrome at the Mayo Clinic from 1984 to 2004 was conducted. Demographic data, examination findings, and treatments were noted. RESULTS We identified 54 patients who met criteria for inclusion in the study. Twenty-six patients (48%) had en coup de sabre morphea, 13 (24%) had Parry-Romberg syndrome, and 15 (28%) had both. Disease was present bilaterally in 7.4% of patients. Thirteen percent of all patients in the study group had seizures. Of patients who received treatment, most were treated with antimalarial agents (57.1%) or methotrexate (28.6%). LIMITATIONS The study design was that of a retrospective review at a tertiary care center with referral bias. There were also limitations present because of the inherent nature of the diseases studied. CONCLUSION En coup de sabre morphea and Parry-Romberg syndrome frequently coexist and are likely both variants of morphea. Bilateral disease is more common than previously reported. The efficacy of antimalarials and methotrexate in the treatment of these diseases remains unclear.

Abstract
DEFINITION AND FREQUENCY: Localized scleroderma, also known as morphea, is a sclerotic condition limited to the skin. The specific clinical entity depends on the extent, linear disposition and depth of the lesions. Morphea is ten times more prevalent than systemic sclerosis, and its prognosis is generally good: superficial forms resolve within 3 years. NO SYSTEMIC INVOLVEMENT In the absence of symptoms, examinations to detect systemic involvement are purposeless. Plaque morphea is the most frequent clinical presentation. Serious manifestations include extensive morphea that may involve the entire skin or linear forms, especially in children, where they may be severe, especially on the face. There are no immunological markers clearly associated with morphea and no causative agents have been implicated in its pathogenesis, although sclerodermiform dermatitis is reported to be associated with some drugs and toxic agents. TREATMENT There is no consensual treatment for morphea. Treatment should be decided according to severity and extent of lesions. Limited lesions may be treated with local steroids such as class IV corticosteroids. Systemic treatment (methotrexate) should be discussed in extensive and linear forms when there is a risk of functional or esthetic complications.

Abstract
Scleroderma had been virtually unrecognized in this country before this study. Our interest in this condition was raised by the discovery that certain patients being investigated for ischaemic disease of the hand had scleroderma. Although uncommon, it is not excessively rare and we have been able to study an increasingly large number of patients, eventually resulting in 177 patients over a period of 35 years. The clinical features in these patients have been delineated. At first, the patients were subdivided into types: type 1, skin changes obvious only in the hands; type 2, skin changes extending beyond the hands but excluding the trunk; type 3, skin changes diffuse and involving the trunk. All types have similar visceral changes, but these are more severe and there is a worse prognosis in type 3 patients. Types 1 and 2 can conveniently be combined as acrosclerosis. Types 1 and 2 have a similar and good prognosis with survival at 30 years of 40%. Type 3 patients have a much worse prognosis, with no type 3 patients living more than 20 years. All types have a high incidence of autoantibodies, but these are generally not related to the severity of the disease and do not occur in relatives or spouses, this being the evidence of the absence of hereditary and environmental factors in their presence. Although patients may receive much relief from symptomatic measures, no treatment had lessened the skin stiffness and there is no specific treatment for the visceral lesions. The cause of the condition remains unknown.

Abstract
BACKGROUND Progressive facial hemiatrophy (PFH) is characterized by a slowly progressive atrophy of soft tissues and in some cases bony structures. Coexisting features of localized scleroderma (LS) are commonly observed, indicating the close nature of both disorders. OBJECTIVE We sought to investigate clinical, serological, and radiographic findings in PFH from 278 patients with LS and to discuss the relationship to linear scleroderma en coup de sabre (LSCS). METHOD A total of 12 patients with PFH were retrospectively evaluated on the basis of clinical, serological, and radiographic findings. RESULTS Five patients (42%) presented with complete PFH, and 7 patients (58%) with partial PFH involving either cheek or forehead. Five of the patients (42%) had a coexisting LSCS lesion, and 3 of them (25%) had concomitant LS of the trunk. Intraoral involvement was present in 6 cases. Neurological involvement was common, in particular, epileptic seizures. Serologic investigations showed neither evidence for infection with Borrelia burgdorferi nor any other indication of underlying systemic immunological disorders. LIMITATIONS There were a relatively small number of patients in a retrospective study. CONCLUSION The reported cases suggest a close relationship between PFH and LSCS. PFH might appear as two different subtypes, one involving cutaneous structures and presenting with clinical features similar to LSCS, one being strictly restricted to subcutaneous structures, primarily affecting the cheek area. The manifold clinical features of central nervous system involvement indicate the pathogenetic importance of neurological involvement in the development of PFH. Magnetic resonance imaging should be included in the tools of standard diagnostic procedures in patients with PFH. The etiologic relevance of autoimmunity as well as preceding trauma should be investigated in larger collective studies.

Abstract
Lyme borreliosis is the most common tick-borne disease which is caused by Borrelia burgdorferi and transmitted in the Poland, as well as Europe, primarily by Ixodes ticks. After inoculation spirochetes spreads in the skin, activate locally immune response mechanisms and cause characteristic skin lesions like erythema migrans, lymphadenosis benigna cutis, erythema migrans multiplex and acrodermatitis chronica atrophicans. The correct clinical diagnosis of skin lesions and antibiotic treatment is most important for regression of symptoms and prevention of late manifestations of Lyme disease.

Abstract
OBJECTIVE Juvenile localized scleroderma (JLS) includes a number of conditions often grouped together. With the long-term goal of developing uniform classification criteria, we studied the epidemiological, clinical and immunological features of children with JLS followed by paediatric rheumatology and dermatology centres. METHODS A large, multicentre, multinational study was conducted by collecting information on the demographics, family history, triggering environmental factors, clinical and laboratory features, and treatment of patients with JLS. RESULTS Seven hundred and fifty patients with JLS from 70 centres were enrolled into the study. The disease duration at diagnosis was 18 months. Linear scleroderma (LS) was the most frequent subtype (65%), followed by plaque morphea (PM) (26%), generalized morphea (GM) (7%) and deep morphea (DM) (2%). As many as 15% of patients had a mixed subtype. Ninety-one patients (12%) had a positive family history for rheumatic or autoimmune diseases; 100 (13.3%) reported environmental events as possible trigger. ANA was positive in 42.3% of the patients, with a higher prevalence in the LS-DM subtype than in the PM-GM subtype. Scl70 was detected in the sera of 3% of the patients, anticentromere antibody in 2%, anti-double-stranded DNA in 4%, anti-cardiolipin antibody in 13% and rheumatoid factor in 16%. Methotrexate was the drug most frequently used, especially during the last 5 yr. CONCLUSION This study represents the largest collection of patients with JLS ever reported. The insidious onset of the disease, the delay in diagnosis, the recognition of mixed subtype and the better definition of the other subtypes should influence our efforts in educating trainees and practitioners and help in developing a comprehensive classification system for this syndrome.

Abstract
OBJECTIVE To investigate a potential association between occupational risk factors and severity markers of systemic sclerosis (SSc) defined by diffuse cutaneous extent, pulmonary involvement, and immunologic profile, i.e., presence of antitopoisomerase I antibody (anti-topo I). METHODS Occupational exposures were assessed in 105 patients with SSc from 1998 to 2002. Exposures to silica dust, welding fumes, solvents, and epoxy resins were investigated. A group of 39 exposed SSc patients and a group of 66 unexposed ones were identified and compared according to severity markers of SSc. The stage of cutaneous extent was defined according to the classification of Leroy, as limited scleroderma (lSSc) or diffuse scleroderma (dSSc). Respiratory status was defined by pulmonary function tests and high resolution computed tomography. Immunological profile was determined by the presence of anti-topo I or anticentromere antibodies (ACA). Statistical relationships between occupational exposures and severity markers of SSc were evaluated using a multiple correspondence analysis and Fisher's exact test. RESULTS Diffuse scleroderma affected mainly patients exposed during their occupational life to toxic agents. There were significant or close to significant associations between toxic exposure and dSSc (p = 0.06), pulmonary involvement (p = 0.10), and negative ACA (p = 0.03). The most incriminated products seemed to be epoxy resins (p = 0.06), white spirit (p = 0.07), aromatic solvents (p = 0.07), and silica coupled to welding fumes (p = 0.10). CONCLUSION Our results indicate that occupational toxic factors have an influence on the severity of SSc.

Abstract
OBJECTIVE Juvenile localized scleroderma is usually considered a disease that is confined to the skin and subcutaneous tissue. We studied the prevalence and clinical features of extracutaneous manifestations in a large cohort of children with juvenile localized scleroderma. METHODS Data from a multinational study on juvenile scleroderma was used for this in-depth study. Clinical features of patients with extracutaneous manifestations were compared with those of patients who had exclusively skin involvement. RESULTS Seven hundred fifty patients entered the study. One hundred sixty-eight patients (22.4%) presented with a total of 193 extracutaneous manifestations, as follows: articular (47.2%), neurologic (17.1%), vascular (9.3%), ocular (8.3%), gastrointestinal (6.2%), respiratory (2.6%), cardiac (1%), and renal (1%). Other autoimmune conditions were present in 7.3% of patients. Neurologic involvement consisted of epilepsy, central nervous system vasculitis, peripheral neuropathy, vascular malformations, headache, and neuroimaging abnormalities. Ocular manifestations were episcleritis, uveitis, xerophthalmia, glaucoma, and papilledema. In more than one-fourth of these children, articular, neurologic, and ocular involvements were unrelated to the site of skin lesions. Raynaud's phenomenon was reported in 16 patients. Respiratory involvement consisted essentially of restrictive lung disease. Gastrointestinal involvement was reported in 12 patients and consisted exclusively of gastroesophageal reflux. Thirty patients (4%) had multiple extracutaneous features, but systemic sclerosis (SSc) developed in only 1 patient. In patients with extracutaneous involvement, the prevalence of antinuclear antibodies and rheumatoid factor was significantly higher than that among patients with only skin involvement. However, Scl-70 and anticentromere, markers of SSc, were not significantly increased. CONCLUSION Extracutaneous manifestations of juvenile localized scleroderma developed in almost one-fourth of the children in this study. These extracutaneous manifestations often were unrelated to the site of the skin lesions and sometimes were associated with multiple organ involvement. The risk of developing SSc was very low. This subgroup of patients with juvenile localized scleroderma should be evaluated extensively, treated more aggressively, and monitored carefully.

Abstract
Clinical examination and transthoracic echocardiography play a vital role in the management of patients with pericardial effusion and cardiac tamponade physiology. We report patients in advanced phase 3 cardiac tamponade with variant clinical and hemodynamic presentations. These atypical cardiac tamponade cases include: A patient with severe aortic valve regurgitation who lacked pulsus paradoxus; a patient with systemic sclerosis without hypotension; and a patient with pulmonary hypertension lacking right heart collapse on echocardiography. Recognition of these atypical clinical and hemodynamic manifestations of cardiac tamponade will avoid undue delay in the treatment.

Abstract
OBJECTIVES To describe the neuroimaging and clinical findings in patients with localized scleroderma en coup de sabre (LScs). METHODS Patients with LScs were evaluated by high-resolution MRI and CT. The authors performed three-dimensional reconstructions of MRI and CT scans to evaluate brain and bone structures. RESULTS Nine patients with LScs were evaluated (five women), with ages ranging from 6 to 53 years (mean, 30.7 years). Brain CT showed bone deformities with thinning of the skull under the skin lesions in six patients. MRI scans showed focal atrophy and blurring of the gray-white matter interface localized under the skin lesion in all patients. In three patients it was associated with hyperintense signal on fluid-attenuated inversion recovery (FLAIR) and T2-weighted images. Follow-up MRI showed extension of the brain lesion in one patient; in the remaining patients, the lesion did not progress. Four of the nine patients had partial epilepsy. One had surgery for management of refractory seizures, and pathologic findings indicated a focal inflammatory process. CONCLUSION Localized scleroderma en coup de sabre is associated with focal, and in some progressive, brain lesions underlying the skin atrophy. Epilepsy, when present, is related to these brain lesions. Imaging findings and histopathology indicated that the process, most likely focal inflammatory, may be progressive.

Abstract
OBJECTIVE To determine the prevalence and clinical correlation of anti-DNA topoisomerase IIalpha (anti-topo IIalpha) antibody in patients with localized scleroderma. METHODS Anti-topo IIalpha antibodies or anti-DNA topoisomerase I (topo I) antibodies were determined by enzyme-linked immunosorbent assay (ELISA) and immunoblotting. Inhibition of topo IIalpha enzymatic activity by the antibodies was evaluated by decatenation assays using kinetoplast DNA as a substrate. RESULTS IgG or IgM anti-topo IIalpha antibody was detected in 76% (35 of 46) of patients with localized scleroderma, and in 85% (11 of 13) of patients with generalized morphea, the severest form of localized scleroderma. This prevalence of the antibody in patients with localized scleroderma was much higher than that found in patients with systemic sclerosis (SSc) (5 of 37 [14%]), systemic lupus erythematosus (2 of 26 [8%]), dermatomyositis (2 of 20 [10%]), and in healthy controls (3 of 42 [7%]). Immunoblotting confirmed the presence of IgG anti-topo IIalpha antibody in sera from patients with localized scleroderma and showed no cross-reactivity of anti-topo IIalpha antibody with topo I. Anti-topo I antibody was not detected by ELISA in any sera from patients with localized scleroderma. In addition, anti-topo I antibody from SSc patients did not cross-react with topo IIalpha. The presence of anti-topo IIalpha antibody was associated with a greater total number of sclerotic lesions and number of plaque lesions in patients with localized scleroderma. Furthermore, anti-topo IIalpha antibody was able to inhibit topo IIalpha enzymatic activity. CONCLUSION The results of the present study indicate that anti-topo IIalpha is a major autoantibody in localized scleroderma, and is distinct from anti-topo I antibody in SSc.

Abstract
OBJECTIVE To investigate the relationship of progressive facial hemiatrophy (PFH) and scleroderma en coup de sabre by establishing the presence and type of central nervous system (CNS) involvement in both diseases and the possible coexistence of PFH with scleroderma in other body sites. METHODS We divided 19 cases of PFH into 2 groups: group 1 in which atrophies were preceded by cutaneous indurations (n = 10) and group 2 with no precedent indurations (n = 9). The third group consisted of 7 cases of scleroderma en coup de sabre with no PFH features. Clinical and laboratory investigations included indirect immunofluorescence for antinuclear antibodies, and routine neurological examination involved electroencephalography, magnetic resonance imaging (MRI) before and after contrast application to evaluate the integrity of blood-brain barrier, angio-MRI to evaluate intracranial blood vessel anomalies, and 99mTc-HM-PAO-SPECT to evaluate regional cerebral blood flow (CBF). RESULTS We found similar anomalies in all 3 groups. MRI did not show abnormality in 2 out of 9 PFH cases preceded by indurations, in 5 out of 9 cases not preceded by indurations, and in all 7 cases of scleroderma en coup de sabre, including 5 patients, in whom the CBF was found to be diminished. In single cases of groups 1 and 2, SPECT was normal despite some MRI abnormalities. Angio-MRI was not contributory since the same abnormalities of Willis circle were found in normal controls. In single cases of both PFH groups, MRI with contrast disclosed some damage of the blood-brain barrier. CONCLUSION Our results suggest frequent CNS involvement in PFH cases, regardless of the time of presentation of cutaneous indurations, with or without coexistent plaques of localized scleroderma in other locations. This indicates a close relationship between PFH and scleroderma en coup de sabre. The detection of abnormal SPECT by normal MRI in some cases of PFH and scleroderma en coup de sabre is of practical importance. This indicates the usefulness of SPECT in studying both PFH and scleroderma en coup de sabre.

Abstract
BACKGROUND Previous studies have suggested an increased risk of cancer among patients with scleroderma. OBJECTIVE To study a population based cohort of patients with scleroderma in South Australia. METHODS Subjects with scleroderma were identified from the South Australian Scleroderma Registry established in 1993. All subjects on the scleroderma registry were linked to the South Australian Cancer Registry to identify all cases of cancer until 31 December 2000. Standardised incidence ratios (SIRs) for cancer for subjects with scleroderma were determined using the age- and sex-specific rates for South Australia. RESULTS In 441 patients with scleroderma, 90 cases of cancer were identified, 47 of which developed after inclusion on the scleroderma registry. The SIRs for all cancers among these patients were significantly increased (SIR=1.99; 95% confidence interval (95% CI) 1.46 to 2.65) compared with the cancer incidence rates for South Australia. The SIRs for lung cancer (SIR=5.9; 95% CI 3.05 to 10.31) were also significantly increased. The SIRs for all cancers among the subgroups with diffuse scleroderma (SIR=2.73; 95% CI 1.31 to 5.02) and limited scleroderma (SIR=1.85; 95% CI 1.23 to 2.68) were significantly increased. CONCLUSIONS This population based cohort study provides evidence that scleroderma is associated with cancer, and in particular, lung cancer. In addition, both diffuse and limited forms of scleroderma are associated with a similarly increased risk of cancer.

Abstract
Body image dissatisfaction and its relationship to psychosocial function were investigated in 127 women with scleroderma Results indicated elevated body image dissatisfaction, with participants reporting higher levels than a sample of patients with severe burn injuries. Age, skin tightening above the elbows, and functional disability were related to heightened body image dissatisfaction, suggesting that younger patients with more severe disease may be at greatest risk for developing body image concerns. Path analysis revealed that depression mediated the relationship between body image dissatisfaction and psychosocial function. Results suggest that body image dissatisfaction is a significant concern in women with scleroderma and should be assessed routinely. Early identification and treatment of body image dissatisfaction may help prevent the development of depression and psychosocial impairment in this population.

Abstract
We examined, retrospectively, 239 patients (113 adults and 126 children) with LS, referred to our department from 1980 up to 2001. Clinical parameters evaluated were age, sex, LS variant, extracutaneous manifestations, duration of disease and follow-up. We also considered laboratory findings, most notably erythrocyte sedimentation rate, blood eosinophilia, antinuclear antibodies (ANA) and various circulating autoantibodies. Plaque morphea was the most common form in both groups (74 adults and 61 children). In contrast, linear scleroderma affected children much more frequently than adults (22 children vs 7 adults). When the limbs were involved, this variant could lead to severe orthopedic complications (10 children vs one adult patient). On the other hand, linear scleroderma of the scalp and face comprising scleroderma en coup de sabre and Parry-Romberg syndrome was also more frequent in children (14 children vs 5 adults) causing ocular (8 cases), oral (7 cases) and neurologic (8 cases) abnormalities. Typical of childhood were mixed forms (18 pediatric patients), characterized by combination of different LS variants, which usually followed a more protracted and complicated course and showed ANA positivity (11 cases). Among adults, Raynaud's phenomenon was found in 8 patients; interestingly, anticentromere antibodies were detected in 4 of these subjects, identifying a subset at risk for progression to systemic disease. Children and adults developed LS with analogous clinical and immunological features. However, the prevalence of LS variants differed between adult and pediatric populations, leading to different extracutaneous complications.

Abstract
Scleroderma is a heterogenous connective tissue disorder characterized by fibrosis of the skin, with or without internal organ involvement. The aetiology of scleroderma may involve both environmental and genetic factors. Abnormalities involving the immune system, vascular tissue and extracellular matrix have been demonstrated. Recent research has focused on microchimerism as a risk factor for the development of scleroderma. This article reviews the epidemiology and pathogenesis of this disorder.

Abstract
The scleroderma disorders remain challenging conditions in pediatric rheumatology to understand pathologically and indeed for which to provide care. It is clear that much progress is being made in the clinical approach to understanding this group of group of disorders. It seems likely that the different lesions of LS may represent unique immunopathogenic mechanisms or perhaps reflect unique genetic or other characteristics of the patients themselves. To take advantage of the revolution in therapies now occurring in rheumatology it is critical that controlled clinical trials are developed with appropriate agreed upon outcome measures for both localized and systemic disease.

Abstract
BACKGROUND Lipodermatosclerosis describes bound-down, sclerotic skin involving the lower extremities. OBJECTIVE Our purpose was to describe the demographic and clinical features of patients with lipodermatosclerosis. METHODS This was a retrospective study of patients presenting to Mayo Clinic between 1976 and 1998 with a diagnosis of lipodermatosclerosis. RESULTS Of 97 patients, 84 (87%) were women. Mean age was 62 years (range, 25-88 years). Mean body mass index was 34.3 (range, 17.8-71.5). Clinical signs were bilateral involvement in 44 patients (45%), induration localized to a discrete plaque in 49 (51%), erythema in 69 (71%), hyperpigmentation in 57 (59%), ulceration in 13 (13%), concomitant edema in 69 (71%), and varicosities in 55 (57%). Vascular studies performed on 72 patients showed abnormalities in 49: deep venous incompetence in 33 (67%), calf muscle pump abnormality in 19 (39%), abnormal pulsatility in 10 (20%), and obstruction in 1 (2%). CONCLUSION Lipodermatosclerosis was associated with female sex, middle age, high body mass index, and venous abnormalities.

Abstract
Scleroderma is a broad term encompassing both localized and systemic sclerosis. Localized scleroderma is a cutaneous limited fibrosis that manifests as plaque morphea, generalized morphea, linear scleroderma, and deep morphea. Systemic scleroderma (sclerosis) can manifest as either limited or diffuse disease. Limited systemic sclerosis is typically preceded by Raynaud's phenomenon, involves cutaneous sclerosis distal to the elbows, with gastrointestinal and pulmonary fibrosis, and anticentromere antibody positivity. Diffuse systemic scleroderma is characterized by simultaneous Raynaud's phenomenon, cutaneous skin involvement proximal to the elbow with gastrointestinal, pulmonary, renal and cardiac fibrosis, and positive serology for antitopoisomerase and anti-RNAP III antibodies. This article discusses the classification, epidemiology, pathogenesis, clinical manifestations, treatment, and prognosis of the scleroderma.

Abstract
The authors used "internal validity analysis" to evaluate the performance of various capture-recapture methods. Data from studies with five overlapping, incomplete lists generated subgroups whose known sizes were compared with estimates derived from various four-source capture-recapture analyses. In 15 data sets unanalyzed previously (five subgroups of each of three new studies), the authors observed a trend toward mean underestimation of the known population size by 16-25%. (Coverage of the 90% confidence intervals associated with the method found to be optimal was acceptable (13/15), despite the downward bias.) The authors conjectured that (with the obvious exception of geographically disparate lists) most data sets used by epidemiologists tend to have a net positive dependence; that is, cases captured by one source are more likely to be captured by some other available source than are cases selected randomly from the population, and this trend results in a bias toward underestimation. Attempts to ensure that the underlying assumptions of the methods are met, such as minimizing (or adjusting adequately) for the possibility of loss due to death or migration, as was undertaken in one exceptional study, appear likely to improve the behavior of these methods.

Abstract
15 renal dialysis patients have been identified with a skin condition characterised by thickening and hardening of the skin of the extremities and an increase in dermal fibroblast-like cells associated with collagen remodelling and mucin deposition. The disease closely resembles scleromyxoedema, yet has significant enough clinical and histopathological differences to warrant its designation as a new clinicopathological entity.

Abstract
BACKGROUND Scleroderma is uncommon in childhood. The aim of our study was to analyze the frequency of different clinical forms, their prognostic significance, biological features, and co-morbidities and to assess the pertinence of therapeutic options. PATIENTS AND METHODS The files of 70 children with primary scleroderma seen from 1980 to 1997 were retrospectively reviewed. RESULTS Localized scleroderma was observed in 56 children and diffuse lesions in 14. Localized scleroderma (44 girls, 12 boys) began early at a mean age of 7 years 2 months. The lesions presented as isolated bands (39 p. 100), associated with morphea (36 p. 100), or multiple morphea (5 p. 100). Mean duration of the clinical course was longer in cases with more and deeper lesions. Eosinophilia was observed at onset in 38 p. 100 of the cases and antinuclear antibodies were found in 28 p. 100. Local corticosteroid therapy (level I or II) appeared to be useful in the superficial and active lesions (morphea) but did not halt progression to deep scleroderma. General corticosteroid therapy (1 mg/kg/24 h) did not prevent the development of sequelae in cases with bands (16/16). Diffuse scleroderma corresponded to systemic scleroderma (6 cases), dual morbidity (dermatomyositis, mixed connective tissue disease) (6 cases), or scleroderma after eosinophil fasciitis (2 cases). Age at onset was around 9 years with female predominance. A particular gloves and socks form was observed and cardiac involvement was common, but there was no case of renal involvement. The therapeutic problems were similar to those in adults. DISCUSSION Our findings emphasize that scleroderma occurs readily in childhood, unlike what has been reported 10 years ago. Prognosis depends on functional impairment resulting from major sequelae particularly important in localized forms and the life-threatening situations occurring in systemic forms.

Abstract
Localized scleroderma refers to a diverse spectrum of disorders that involve fibrosis of the skin. Children are more likely than adults to develop localized forms of scleroderma. This condition may have devastating effects on growth and development such as limb asymmetry, flexion contractures, and psychological disability. The pathogenesis of localized scleroderma is unknown but its possible relation to Borrelial infection is discussed. This article reviews associated laboratory and radiologic abnormalities, and discusses implications for monitoring disease activity. There is no universally effective therapy for this idiopathic condition and therapy is limited. A rationale for treatment based on disease subtype and severity is provided.

Abstract
PURPOSE There have been few studies of connective tissue diseases in Africa. METHODS A retrospective study was conducted in order to describe the various connective tissue diseases and their semiological profile in patients attending the dermatology and rheumatology units at Lomé hospital. RESULTS Clinical examinations showed that eighty-four (0.2%) out of the 34,169 patients were suffering from connective tissue diseases. Diseases that were encountered were the following: scleroderma (18 cases), systemic lupus erythematosus (four cases), discoid lupus erythematosus (15 cases), rheumatoid arthritis (29 cases), polymyositis and dermatomyositis (16 cases), juvenile rheumatoid arthritis (one case), giant cell arteritis (one case). Raynaud's syndrome was present in six out of the 18 patients suffering from scleroderma. Nephrotic syndrome was observed in a patient suffering from systemic lupus erythematosus. A septicemia caused this patient's death. Two patients suffering from polymyositis had cancer. No etiology was found in the 14 other patients. Hip involvement was present in two patients suffering from rheumatoid arthritis. Patients with rheumatoid arthritis had no systemic involvement (nodulitis, vasculitis). CONCLUSION Our results are in agreement with those of previous studies on connective tissue diseases in Africa. However, further studies are required to better understand the epidemiological and semiological profiles of connective tissue diseases in Africa.

Abstract
The purpose of this retrospective study was to determine the epidemiological and semiological profile of scleroderma in Black Africa. Medical records of patients who consulted in the Dermatology Clinic and the Rheumatology Clinic of the Teaching Hospital in Lomé, Togo between 1980 and 1996 and between 1989 and 1996 respectively were reviewed. Scleroderma was diagnosed in 18 of the 34,169 patients seen during the study periods (0,05%). The disease was systemic in 13 cases (8 females, 5 males; mean age: 31 years) and localized in 5 cases (mean age: 20 years). There were no predisposing occupational or therapeutic factors. The clinical manifestations were Raynaud's phenomenon in six of the 13 patients with systemic scleroderma. Extensive cutaneous sclerosis in 10 cases, poikiloderma in seven cases, dysphagia in three cases, pulmonary fibrosis in four cases, and polyarthralgia in two cases. Myalgia and renal involvement were not observed. The findings of this study documents the low incidence of scleroderma in Togo. The high frequency of extensive cutaneous sclerosis, poikiloderma and low frequency of Raynaud's phenomenon which were often mild are the most remarkable features of the disease in Lomé. These features have been pointed out previously but epidemiologic data is still insufficient to confirm the existence of an African form of scleroderma.

Abstract
Scleroderma is classified as two separate but related entities, a localized form and a systemic form. The classification scheme for morphea presented here is that of Peterson et al, which divides morphea into five categories: plaque, generalized, bullous, linear, and deep. Using this system, these authors estimated the incidence rate of localized scleroderma to be 27 new cases per million population per year. Overall survival was similar to that of the general population. There was a preponderance of female cases (approximately 3:1) for all forms of morphea except for linear scleroderma, which had an even sex distribution. Systemic scleroderma is divided into limited and diffuse disease based on the extent of skin involvement. Recent estimates have placed the incidence rate of systemic sclerosis in the United States at 19 new cases per million adults per year, with an overall prevalence of 240/million adults. The female-to-male ratio is approximately 5:1. The prevalence of scleroderma varies by geographic region and ethnic background and is higher in the United States than in Europe or Japan. Although systemic sclerosis survival has improved over the past two decades, with 5-year survival over 80%, long-term survival is significantly lower than expected, and morbidity is considerable.

Abstract
Scleroderma is a diverse group of conditions which have in common fibrosis of skin and other tissues. Although less common in children than in adults, these conditions are an important cause of morbidity and occasional mortality when they occur in the pediatric population. Children are more likely than adults to develop localized forms of scleroderma, and because of the impact on growth, these can result in major facial or limb asymmetry, flexion contractures, and disability. Management approaches must take into consideration the effect of medications on the child (for example, growth failure and osteoporosis from corticosteroids) as well as the psychosocial impact of chronic illness and physical deformity on the child and family. This article describes the types of scleroderma identified in children, reviews epidemiologic and etiologic factors, and discusses management options. Because this is a rare group of diseases managed by both dermatologists and rheumatologists, large series of patients are rare, and controlled studies of management are not available.
