2003-01-01

A 2-year-old male German shepherd dog in poor bodily condition was evaluated for thoracic limb lameness due to a large, firm mass medial to the left cranial scapula. Radiography revealed several large cauliflower-like mineralized masses in the craniomedial left scapula musculature, pectoral region and bilaterally in the biceps tendon sheaths. Urinalysis, haematology and serum biochemistry showed that the dog was severely anaemic, hyperphosphataemic and in chronic renal failure. The dog was euthanased and a full post mortem performed. A diagnosis of chronic renal failure with secondary hyperparathyroidism was confirmed. The mineralised masses were grossly and histopathologically consistent with a diagnosis of tumoral calcinosis. Tumoral calcinosis associated with chronic renal failure that does not involve the foot pads is rarely seen

Full Text Available Abstract We report a 14-year-old girl with juvenile dermatomyositis (JDM complicated by severe inflammatory calcinosis successfully treated with thalidomide. She was diagnosed as JDM when she was 4 years old after a few months of increasing lethargy, muscle pain, muscle weakness, and rash. During three months, clinical manifestations and abnormal laboratory findings were effectively treated with oral prednisolone. However, calcinosis was recognized 18 months after disease onset. Generalized calcinosis rapidly progressed with high fever, multiple skin/subcutaneous inflammatory lesions, and increased level of CRP. Fifty mg/day (1.3 mg/kg day of oral thalidomide was given for the first four weeks, and then the dose was increased to 75 mg/day. Clinical manifestations subsided, and inflammatory markers had clearly improved. Frequent high fever and local severe pain with calcinosis were suppressed. The levels of FDP-E, IgG, and tryglyceride, which were all elevated before the thalidomide treatment, were gradually returned to the normal range. Over the 18 months of observation up to the present, she has had no inflammatory calcinosis, or needed any hospitalization, although established calcium deposits still remain. Her condition became painless, less extensive and less inflammatory with the CRP level below 3.08 mg/dL. Recent examination by whole-body 18F-FDG-PET-CT over the 15 months of thalidomide treatment demonstrated fewer hot spots around the subcutaneous calcified lesions.

Full Text Available Subcutis calcinosis, characterized by abnormal calcium deposits in the skin, is a rare complication of using calcium-containing heparin occurring in patients with advanced renal failure. We report the case of an 83-year-old female, a known case of chronic kidney disease (CKD for four years with recent worsening of renal failure requiring hospitalization and hemodialysis. She developed subcutis calcinosis following injection of calcium-containing heparin. Biochemical tests showed serum parathormone level at 400 pg/dL, hypercalcemia, elevated calcium-phosphate product and monoclonal gammopathy related to multiple myeloma. She developed firm subcu-taneous nodules in the abdomen and the thighs, the injection sites of Calciparin ® (calcium nadroparin that was given as a preventive measure against deep vein thrombosis. The diagnosis of subcutis calcinosis was confirmed by the histological examination showing calcium deposit in the dermis and hypodermis. These lesions completely disappeared after discontinuing calcium nadro-parin injections. Subcutis calcinosis caused by injections of calcium-containing heparin is rare, and, to the best our knowledge, not more than 12 cases have been reported in the literature. Pathogenesis is not well established but is attributed to the calcium disorders usually seen in advanced renal failure. Diagnosis is confirmed by histological tests. Outcome is mostly favorable. The main differential diagnosis is calciphylaxis, which has a poor prognosis. Even though rarely reported, we should be aware that CKD patients with elevated calcium-phosphorus product can develop subcutis calcinosis induced by calcium-containing heparin. When it occurs, fortunately and unlike calci-phylaxis, outcome is favorable.

Hodnett, P

We present the case of a young adult patient with chronic renal failure who developed painful subcutaneous nodules after failed renal transplant and recommencing dialysis. These nodules were juxta-articular in location and initially located over both shoulders. Radiological evaluation suggested tumoral calcinosis. The patient was placed on a strict dialysis and dietary regimen but was suboptimally compliant with same. The patient developed progressive disease with an increase in size and number of juxta-articular calcified soft-tissue masses. However, 6 months following a second renal transplant clinical and radiological follow up demonstrated marked resolution both in symptomatology and radiographic findings. We present the plain radiographic, CT and MRI findings which demonstrate the typical radiological features of tumoral calcinosis. We correlate these findings with clinical course and histological findings following surgical excision of one of these masses.

Tumoral calcinosis is a rare, familial ectopic calcification syndrome associated with hyperphosphataemia. A family in which seven of 13 siblings had demonstrable, clinical, radiological and pathological findings of tumoral calcinosis was evaluated. The purposes were to compare the efficacy of bone scintiscans with serum phosphorus determination in detecting subclinical disease early in asymptomatic siblings and to assess therapeutic results in affected family members following initiation of phosphate depletion therapy. History, physical examination, serum calcium, serum phosphorus and bone scintiscans were performed in 12 of 13 siblings. All the affected siblings had markedly elevated serum phosphorus levels and abnormal bone scintiscans while the unaffected siblings had normal serum phosphorus levels and normal bone scintiscans. All the siblings, affected and unaffected, were normocalcaemic. After initiation of phosphate depletion therapy, gross changes in the appearance of lesions were detected on bone scintiscans. Serum phosphorus levels likewise showed a modest decline, although still remaining in the hyperphosphataemic range. In conclusion, bone scintiscans and serum phosphorus determinations are equally sensitive in detecting subclinical disease. However, the scintiscans are helpful in assessing not only the extent of the disease, but also whole-body and regional changes following any therapeutic interventions. (author)

Three juvenile, genetically related African lions (Panthera leo) were evaluated for discrete dome-shaped subcutaneous masses present over the proximal lateral metatarsal-tarsal area. The lesions measured 3-8 cm in diameter, were fluctuant to firm, nonulcerated, and attached to underlying structures. On radiographic evaluation, the lesions were characterized by well-circumscribed punctate mineralizations in the soft tissue surrounded by soft tissue swelling without evidence of adjacent bony involvement. On cut surface, the lesions were made of numerous loculi containing 2-5-mm round-to-ovoid, white-to-gray, firm structures interspersed with fibrous tissue and pockets of serosanguinous fluid. Hematology, serum biochemistry, serum thyroid screening (including total thyroxine, total triiodothyronine, free thyroxine, and free triiodothyronine), and serum vitamin D panels (including parathyroid hormone, ionized calcium, and 25-hydroxyvitamin D) were unremarkable. Histopathologic evaluation of the lesions was consistent with calcinosis circumscripta with fibroplasia, chronic inflammation, and seroma formation. An additional two genetically related lions were considered suspect for calcinosis circumscripta based on presentation, exam findings, and similarity to the confirmed cases. All masses self-regressed and were not associated with additional clinical signs other than initial lameness in two cases.

calcinosis in children and adolescents with juvenile dermatomyositis. METHODS: A review was carried out of the medical records of 54 patients with juvenile dermatomyositis. Data were collected on demographic characteristics, clinical features: muscle strength (stages I to V of the Medical Research Council scale, pulmonary involvement (restrictive pulmonary disease with presence or absence of anti-Jo1 antibodies, gastrointestinal problems (gastroesophageal reflux and/or heart disease (pericarditis and/or myocarditis; laboratory tests: elevated muscle enzyme levels in serum (creatine phosphokinase, aspartate aminotransferase, alanine aminotransferase and/or lactate dehydrogenase; and on the treatments given: corticoid therapy in isolation or associated with hydroxychloroquine and/or immunosuppressants. The patients were divided into two groups, depending on presence or absence of calcinosis and data were evaluated by both univariate and multivariate analyses. RESULTS: Calcinosis was identified in 23 (43% patients, and in six (26% patients it had emerged prior to diagnosis while in 17 (74% it was post diagnosis. The univariate analysis revealed that cardiac (p = 0.01 and pulmonary (p = 0.02 involvement and the need for one or more immunosuppressor (methotrexate, cyclosporine A and/or pulse therapy with intravenous cyclophosphamide to treat juvenile dermatomyositis (p = 0.03 were all associated with an increased incidence of calcinosis. The multivariate analysis then demonstrated that only cardiac involvement (OR = 15.56; 95%CI 1.59-152.2 and the use of one or more immunosuppressor (OR = 4.01; 95%CI 1.08-14.87 were independently associated with the presence of calcinosis. CONCLUSIONS: Calcinosis was a frequent development among these juvenile dermatomyositis cases, generally emerging as the disease progressed. Calcinosis was associated with the more severe cases that also had cardiac involvement and where immunosuppressors had to be included in the treatment.

Familial tumoral calcinosis is characterized by ectopic calcifications and hyperphosphatemia due to inactivating mutations in FGF23 or UDP-N-acetyl-α-D-galactosamine:polypeptide N-acetylgalactosaminyltransferase 3 (GALNT3). Herein we report a homozygous missense mutation (H193R) in the KLOTHO (KL) gene of a 13-year-old girl who presented with severe tumoral calcinosis with dural and carotid artery calcifications. This patient exhibited defects in mineral ion homeostasis with marked hyperphosphatemia and hypercalcemia as well as elevated serum levels of parathyroid hormone and FGF23. Mapping of H193R mutation onto the crystal structure of myrosinase, a plant homolog of KL, revealed that this histidine residue was at the base of the deep catalytic cleft and mutation of this histidine to arginine should destabilize the putative glycosidase domain (KL1) of KL, thereby attenuating production of membrane-bound and secreted KL. Indeed, compared with wild-type KL, expression and secretion of H193R KL were markedly reduced in vitro, resulting in diminished ability of FGF23 to signal via its cognate FGF receptors. Taken together, our findings provide what we believe to be the first evidence that loss-of-function mutations in human KL impair FGF23 bioactivity, underscoring the essential role of KL in FGF23-mediated phosphate and vitamin D homeostasis in humans.

Three patients are described who were examined with the bone-seeking substance sup(99m)Tc-E.H.D.P. The abnormalities discovered were ascribed to metastatic calcification in the lungs. The patiens suffered from three quite different conditions, but in each there was hypercalcaemia. One patient had chronic renal insufficiency with secondary hyperparathyroidism, in the other cases the cause of the hypercalcaemia could not be determined. In one patient, it was possible to confirm the diagnosis of pulmonary calcinosis histologically. Previously published cases indicate that it is possible to demonstrate lung calcification by using Tc-phosphate compounds, particularly sup(99m)Tc-E.H.D.P. This is important, since it is often not possible to demonstrate it radiologically. It further demonstrates that the accumulation of sup(99m)Tc-E.H.D.P. is dependent on active bone metabolism.

To report on the biochemistry and clinical and genetic findings of two siblings, the younger sister presenting with recurrent bone pain of the radius and ulna, and medullary sclerosis, and the older brother with soft tissue calcific deposits (tumoral calcinosis) but who later developed bone pain. Both were found to be hyperphosphaturic. The index family comprised four individuals (father, mother, brother, sister). The affected siblings were the offspring of a non-consanguineous Indian family of Tamil origin. Bidirectional sequencing was performed on the DNA from the index family and on 160 alleles from a population of 80 unrelated unaffected control individuals of Tamil extraction and 72 alleles from individuals of non-Tamil origin. Two symptomatic siblings were found to harbour previously unreported compound heterozygous missense UDP-N-acetyl-D-galactosamine: polypeptide N-acetylgalactosaminyltransferase 3 (GalNAc-transferase; GALNT3) mutations in exon 4 c.842A>G and exon 5 c.1097T>G. This sequence variation was not detected in the control DNA. This is the first report of siblings exhibiting stigmata of familial tumoral calcinosis and hyperostosis-hyperphosphataemia syndrome with documented evidence of autosomal recessive missense GALNT3 mutations. The findings from this family add further evidence to the literature that familial tumoral calcinosis and hyperostosis-hyperphosphataemia syndrome are manifestations of the same disease and highlight the importance of appropriate metabolic and genetic investigations.

Mariana Espiga Maioli

Full Text Available Abstract Tumoral calcinosis is an uncommon type of extraosseous calcification characterized by large rubbery or cystic masses containing calcium-phosphate deposits. The condition prevails in the periarticular tissue with preservation of osteoarticular structures. Elevated calcium-phosphorus products and severe secondary hyperparathyroidism are present in most patients with uremic tumoral calcionosis (UTC. Case report of an obese secondary to chronic glomerulonephritis, undergoing continuous ambulatory peritoneal dialysis (CAPD reported the appearance of painless tumors in the medial surface of fifth finger and left arm. Tumoral calcinosis was confirmed by left biceps biopsy. Poor adherence to CAPD. The patient was transferred to the "tidal" modality of peritoneal dialysis and after was treated by hemodialysis, despite the persistence of severe hyperparathyroidism progressive reduction of UTC until near to its complete disappearance. Nowadays, one year after patient received deceased-donor kidney transplantation, he presents with an improvement in secondary hyperparathyroidism. UTC should be included in the elucidation of periarticular calcification of every patient on dialysis. Relevant laboratory findings such as secondary hyperparathyroidism and elevated calcium- phosphorus products in the presence of periarticular calcification should draw attention to the diagnosis of UTC.

Full Text Available Tumoral calcinosis (TC is a rare condition in which there is periarticular calcium deposition in the soft tissue forming a mass. The most common locations of TC are the larger joints such as the hip, shoulder, and knee, as well as the hands and wrists. Patients will often present with localized swelling, pain, and reduced joint mobility. We will discuss a 48-year-old male on hemodialysis who presented with a fever of unknown source and diffuse joint pain. He was found to have progressive, multiple tumor-like swellings on his shoulders, hands, and knees. He was diagnosed with TC and managed with a high dose phosphate binder with resolution of his fever and improvement in his pain.

Prostaglandin PGE2: a possible mechanism for bone destruction in calcinosis circumscripta.

1978-02-28

A patient showed evident osteolysis in phalanges and heavy periarticular calcium deposits of the fingers, wrists and toes which avidly took up 47Ca. The dense, white, tooth-paste like fluid contained in the periarticular calcium deposits has been studied by two different X-ray diffraction methods, by Ubatuba's bioassay for prostaglandin, by thin layer chromatography and by mass spectrometry. The calcium deposits were hydroxyapatite and prostaglandin PGE2 was detected in them. The bone resorption stimulating activity of PGE2 would be expected to result in increased bone destruction with release of calcium salts and this could be a working hypothesis of the pathogenesis of calcinosis circumscripta.

Spinal tumoral calcinosis is reported in a Berner sennenhund puppy. The condition was manifested clinically as a non-ambulatory tetraparesis associated with neck pain. On survey radiographs there was a focal calcified mass at the atlantoaxial articulation. Computed tomography and computed tomographic myelography gave additional information on the extent of the mass and on the degree of spinal cord compression. The mass was removed surgically and the dog made a complete recovery

Autoantibodies to a 140-kd protein in juvenile dermatomyositis are associated with calcinosis.

LENUS (Irish Health Repository)

Gunawardena, H

2009-06-01

OBJECTIVE: The identification of novel autoantibodies in juvenile dermatomyositis (DM) may have etiologic and clinical implications. The aim of this study was to describe autoantibodies to a 140-kd protein in children recruited to the Juvenile DM National Registry and Repository for UK and Ireland. METHODS: Clinical data and sera were collected from children with juvenile myositis. Sera that recognized a 140-kd protein by immunoprecipitation were identified. The identity of the p140 autoantigen was investigated by immunoprecipitation\\/immunodepletion, using commercial monoclonal antibodies to NXP-2, reference anti-p140, and anti-p155\\/140, the other autoantibody recently described in juvenile DM. DNA samples from 100 Caucasian children with myositis were genotyped for HLA class II haplotype associations and compared with those from 864 randomly selected UK Caucasian control subjects. RESULTS: Sera from 37 (23%) of 162 patients with juvenile myositis were positive for anti-p140 autoantibodies, which were detected exclusively in patients with juvenile DM and not in patients with juvenile DM-overlap syndrome or control subjects. No anti-p140 antibody-positive patients were positive for other recognized autoantibodies. Immunodepletion suggested that the identity of p140 was consistent with NXP-2 (the previously identified MJ autoantigen). In children with anti-p140 antibodies, the association with calcinosis was significant compared with the rest of the cohort (corrected P < 0.005, odds ratio 7.0, 95% confidence interval 3.0-16.1). The clinical features of patients with anti-p140 autoantibodies were different from those of children with anti-p155\\/140 autoantibodies. The presence of HLA-DRB1*08 was a possible risk factor for anti-p140 autoantibody positivity. CONCLUSION: This study has established that anti-p140 autoantibodies represent a major autoantibody subset in juvenile DM. This specificity may identify a further immunogenetic and clinical phenotype within the

We present the case of a 35-year-old man with calcinosis, Raynaud's phenomenon, esophageal dysmotility, sclerodactyly and telangiectasia variant scleroderma who presented with dysphagia, Raynaud's phenomenon and calf pain. 99m Tc-methylene diphosphonate bone scintigraphy was performed to identify the extent of the calcification. It revealed extensive dystrophic calcification in the left thigh and bilateral legs which was involving the muscles and was well-delineated on single photon emission computed tomography/computed tomography. Calcinosis in scleroderma usually involves the skin but can be found in deeper periarticular tissues. Myopathy is associated with a poor prognosis

Mutations in the GALNT3 gene cause tumoral calcinosis characterized by ectopic calcifications due to persistent hyperphosphatemia. We recently developed Galnt3 knockout mice in a mixed background, which had hyperphosphatemia with increased bone mineral density (BMD) and infertility in males. To test the effect of dietary phosphate intake on their phenotype, Galnt3 knockout mice were generated in the C57BL/6J strain and fed various phosphate diets: 0.1% (low), 0.3% (low normal), 0.6% (normal), and 1.65% (high). Sera were analyzed for calcium, phosphorus, alkaline phosphatase, creatinine, blood urine nitrogen, 1,25-dihydroxyvitamin D, osteocalcin, tartrate-resistant acid phosphatase 5b, and fibroblast growth factor 23 (Fgf23). Femurs were evaluated by dual-energy x-ray absorptiometry, dynamic histomorphometry, and/or microcomputed tomography. Galnt3 knockout mice in C57BL/6J had the same biochemical phenotype observed in our previous study: hyperphosphatemia, inappropriately normal 1,25-dihydroxyvitamin D level, decreased alkaline phosphatase activity, and low intact Fgf23 concentration but high Fgf23 fragments. Skeletal analyses of their femurs revealed significantly high BMD with increased cortical bone area and trabecular bone volume. On all four phosphate diets, Galnt3 knockout mice had consistently higher phosphorus levels and lower alkaline phosphatase and intact Fgf23 concentrations than littermate controls. The low-phosphate diet normalized serum phosphorus, alkaline phosphatase, and areal BMD but failed to correct male infertility in Galnt3 knockout mice. The high-phosphate diet did not increase serum phosphorus concentration in either mutant or control mice due to a compensatory increase in circulating intact Fgf23 levels. In conclusion, dietary phosphate restriction normalizes biochemical and skeletal phenotypes of Galnt3 knockout mice and, thus, can be an effective therapy for tumoral calcinosis.

Familial tumoral calcinosis (FTC)/hyperostosis-hyperphosphatemia syndrome (HHS) is a rare disorder caused by mutations in the genes encoding fibroblast growth factor-23 (FGF23), N-acetylgalactosaminyltransferase 3 (GALNT3), or KLOTHO. The result is functional deficiency of, or resistance to, intact FGF23 (iFGF23), causing hyperphosphatemia, increased renal tubular reabsorption of phosphorus (TRP), elevated or inappropriately normal 1,25-dihydroxyvitamin D3 (1,25D), ectopic calcifications and/or diaphyseal hyperostosis. Eight subjects with FTC/HHS were studied and treated. Clinical manifestations varied, even within families, ranging from asymptomatic to large, disabling calcifications. All subjects had hyperphosphatemia, increased TRP, and elevated or inappropriately normal 1,25D. C-terminal FGF23 was markedly elevated while iFGF23 was comparatively low, consistent with increased FGF23 cleavage. Radiographs ranged from diaphyseal hyperostosis to massive calcification. Two subjects with severe calcifications also had overwhelming systemic inflammation and elevated C-reactive protein (CRP). GALNT3 mutations were identified in 7 subjects; no causative mutation was found in the eighth. Biopsies from 4 subjects showed ectopic calcification and chronic inflammation, with areas of heterotopic ossification observed in 1 subject. Treatment with low phosphate diet, phosphate binders, and phosphaturia-inducing therapies was prescribed with variable response. One subject experienced complete resolution of a calcific mass after 13 months of medical treatment. In the 2 subjects with systemic inflammation, interleukin-1 (IL-1) antagonists significantly decreased CRP levels with resolution of calcinosis cutis and peri-lesional inflammation in one subject and improvement of overall well-being in both subjects. This cohort expands the phenotype and genotype of FTC/HHS and demonstrates the range of clinical manifestations despite similar biochemical profiles and genetic mutations

Full Text Available Mucocele is an uncommon pathology of the vermiform appendix estimated to be seen in 0.2-0.3%. The term mucocele means dilation of the appendix due to mucus, caused either by a benign or a malignant process. Herein, we report the case of a 77-year-old man with Calcinosis, Raynaud’s phenomenon, Esophageal dysfunction, Sclerodactyly and Telangiectasias syndrome, a limited form of Scleroderma, who had presented an abdominal cyclical pain and in which abdominopelvic computed tomography scan concluded to the diagnosis of appendiceal mucocele. Surgery and histopathology confirmed the diagnosis of mucinous cystadenoma. This association appendiceal mucocele and scleoderma has not been previously reported. The clinical and radiological features of this unusual complication are reviewed.

To characterize ultrasonographic (US) features in the hand of patients with systemic sclerosis (SSc) and to evaluate the sensitivity of US in the detection of calcinosis and acroosteolysis. The local ethics committee approved this study, and oral informed consent was obtained. A total of 44 consecutive patients with SSc (34 women; mean age, 56.1 years ± 12.1 [standard deviation]; 10 men; mean age, 45.0 years ± 14.0) and 30 healthy control subjects (20 women; mean age, 46.3 years ± 12.1; 10 men; mean age, 39.6 years ± 10.8) were included between October 2010 and December 2011. Bilateral US, including Doppler assessment of the wrists, hands, and fingers, was performed, and presence of synovitis, tenosynovitis with or without a layered appearance, calcifications, acroosteolysis, and distal vascularization was recorded. Radiography of both hands was performed to assess for acroosteolysis and calcinosis. Frequency of US features, sensitivity of US for calcinosis and acroosteolysis, and respective confidence intervals were calculated. Synovitis was found in 17 patients (39%). Tenosynovitis was found in 12 patients (27%), and it had a layered pattern in 15 (41%) of 37 cases. Calcinosis was found in 17 patients (39%) with US, with a sensitivity of 89%. Acroosteolysis was found in nine (20%) patients with US and in 10 (23%) patients with radiography, with 90% sensitivity for US. Distal vascularization was detected in 26 patients (59%) and 30 control subjects (100%) and was in contact with the acroosteolysis bed in seven (78%) of nine patients with SSc. US can be used to assess features of SSc, including synovitis, tenosynovitis, calcinosis, acroosteolysis, and distal vascularization and is sensitive for calcinosis and acroosteolysis detection. A layered pattern (similar to the appearance of an artichoke heart) of tenosynovitis was seen commonly. Online supplemental material is available for this article. © RSNA, 2013.

It is characterized by the formation of calcium deposits in the skin or subcutaneous tissue. It is classified into four subtypes: dystrophic, metastatic, idiopathic or iatrogenic. It may be seen in a variety of systemic diseases such as hyperparathyroidism and hypervitaminosis D, but is most commonly found in dermatomyositis, scleroderma and overlap syndromes and is a rare complication of systemic lupus erythematosus. The management of secondary complications and the success of therapy are constant challenges in the follow-up of these cases.

.Sclerodactyly with acroosteolysis (AO) and calcinosis are prominent features of systemic sclerosis (SSc), but the pathogenesis of these findings is poorly understood. Vitamin D and parathyroid hormone (PTH) have a crucial role in bone metabolism and resorption and may affect AO and calcinosis. We assessed vitamin D and PTH in patients with SSc. Medical records of 134 consecutive patients with SSc (American College of Rheumatology criteria) followed at the rheumatology department during the years 2003-2006 were reviewed for clinical assessment, laboratory evaluation [including 25(OH) vitamin D, calcium, phosphorus, alkaline phosphatase, PTH, creatinine, and albumin]; imaging data confirming AO and/or calcinosis. Patients followed routinely at least once a year were included (81 patients). Of these, 60 patients' medical records were found to have complete, relevant clinical, laboratory, and radiographic imaging. Thirteen patients had diffuse disease and 47 limited disease - 51 women and 9 men, 44 Jews and 16 Arabs; mean age 55 +/- 14 years; disease duration 8 +/- 6 years. AO with or without calcinosis was observed in 42 patients (70%). Vitamin D deficiency was found in 46% of patients (16 out of 44 Jewish patients, 10 out of 16 Arab patients). PTH was elevated in 21.7% of patients. Significant correlations were observed between acroosteolysis and PTH (p = 0.015), calcinosis (p = 0.009), and disease duration (p = 0.008), and between PTH and vitamin D levels (p = 0.01). All patients had normal serum concentrations of calcium, phosphorus, magnesium, and albumin, and liver and kidney functions. In this group of Mediterranean patients with SSc, the incidence of vitamin D deficiency and secondary hyperparathyroidism was surprisingly high. This finding correlated with the occurrence of AO and calcinosis. Low levels of vitamin D may reflect silent malabsorption and might be a risk factor for secondary hyperparathyroidism and bone resorption. Traditional dress habits and low

Full Text Available Morphometric, immunohistochemical and ultrastructural studies were carried out on the diffuse intimal thickening (DIT in arteries of 7 sheep with clinical signs of naturally occurring enzootic calcinosis due to ingestion of the plant Nierembergia veitchii. Arterial lesions consisted of medial deposition of calcium salts and DIT. Calcification of the intima was rare, mild and located near the elastic lamina. By immunohistochemistry a-actin was detected in cells of the media and in cells forming the intimal thickening. Receptors for 1,25(OH2 vitamin D3 were detected in nuclei of intimal, medial and endothelial cells. DIT was irregularly distributed and was neither proportionally related to the intensity of the underlying mineralization area nor to the thickening of the remaining media. Ultrastructural morphometry in smooth muscle cells (SMCs of the media and thickened intima revealed, in the latter, an increase of 318% in the volumetric fraction of those organelles involved in synthesis and a proportional decrease in contractile elements when compared to normal values of media cells. There were histological and ultrastructural evidences of modification of SMCs and their migration to the intima, where they proliferated causing DIT. It was concluded that DIT is a consistent component of arteriosclerotic lesions in N. veitchii induced calcinosis of sheep and that the predominant cell in this process is the SMCs originated from its predecessors of the media. It is suggested that the inducing factor for the arterial changes is 1,25(OH2 D3 present in N. veitchii.Foram feitos estudos morfométrico, imunoistoquímico e ultra-estrutural do espessamento intimal difuso (DIT das artérias de 7 ovinos com sinais clínicos de calcinose enzoótica espontânea causada pela ingestão da planta Nierembergia veitchii.

Basal ganglia calcifications (BGC) may be present in various medical conditions, such as infections, metabolic, psychiatric and neurological diseases, associated with different etiologies and clinical outcomes, including parkinsonism, psychosis, mood swings and dementia. A literature review was performed highlighting the main neuropsychological findings of BGC, with particular attention to clinical reports of cognitive decline. Neuroimaging studies combined with neuropsychological analysis show that some patients have shown progressive disturbances of selective attention, declarative memory and verbal perseveration. Therefore, the calcification process might represent a putative cause for dementia syndromes, suggesting a probable link among calcinosis, the aging process and eventually with neuronal death. The increasing number of reports available will foster a necessary discussion about cerebral calcinosis and its role in determining symptomatology in dementia patients.

Full text: Tumoral calcinosis (TC) is a rare disorder characterised by hyperphosphateamia, normocalceamia and calcified para-articular masses as seen on X-ray. At present, an inborn error of phosphorous metabolism is accepted as the primary cause. Symptoms include pain, swelling, infection and single- or multi-focal lesions. Radionuclide imaging was recently described as the most reliable and simplest method for detection, localisation and assessment of the calcific masses. Bone scintigraphy may demonstrate unsuspected masses even when clinical examination is negative. It is also useful in assessing the effects of surgery and therapy. A 55-year-old male with an 18-year history of TC presented to our department on two occasions. He was first referred to assess the extent of his calcinosis. He had known involvement of the hands, shoulders and pelvis, with little restriction of movement. He had a 6-8 year history of polio which was currently stable. Seven years later he again presented to our department, this time for the evaluation of a suspected fractured hip. On both occasions 800 MBq of 99 mTc-MDP was injected IV and whole body and planar images were obtained at three hours. In the second study, additional dynamic and blood pool images were obtained over the anterior aspect of both hips. Both scans were grossly abnormal and typical of the appearance of widespread TC or calcinosis universalis. Multiple areas of extra osseous uptake involving subcutaneous tissue and muscle of the hands, para-articular regions of both elbows, shoulders and hips were seen and confirmed by X-ray. Localised abnormalities were noted involving left lower neck, left forearm and left foot. Marked progression of the disease was seen in the region of the left shoulder on the second scan.

Digital ulcers (DU) are the most common vascular complication of systemic sclerosis (SSc). We compared the characteristics between patients with prior or current DU with those never affected and evaluated whether a history of DU may be a predictor of vascular, organ involvement, and/or death in patients with SSc. Data from SSc patients with or without prior or current DU were collected by 19 referral centers in an ongoing registry of Spanish SSc patients, named Registro de ESCLErodermia (RESCLE). Demographics, organ involvement, autoimmunity features, nailfold capillary pattern, survival time, and causes of death were analyzed to identify DU related characteristics and survival of the entire series and according to the following cutaneous subsets-diffuse cutaneous SSc (dcSSc), limited cutaneous SSc (lcSSc), and SSc sine scleroderma (ssSSc). Out of 1326, 552 patients enrolled in the RESCLE registry had prior or current DU, 88% were women, the mean age was 50 ± 16 years, and the mean disease duration from first SSc symptom was 7.6 ± 9.6 years. Many significant differences were observed in the univariate analysis between patients with and without prior/current DU. Multivariate analysis identified that history of prior/current DU in patients with SSc was independently associated to younger age at SSc diagnosis, diffuse cutaneous SSc, peripheral vascular manifestations such Raynaud's phenomenon, telangiectasia, and acro-osteolysis but no other vascular features such as pulmonary arterial hypertension or scleroderma renal crisis. DU was also associated to calcinosis cutis, interstitial lung disease, as well as worse survival. Multivariate analysis performed in the cutaneous subsets showed that prior/current DU were independently associated: (1) in dcSSc, to younger age at SSc diagnosis, presence of telangiectasia and calcinosis and rarely a non-SSc pattern on nailfold capillaroscopy; (2) in lcSSc, to younger age at SSc diagnosis, presence of Raynaud's phenomenon as

Calcinosis Cutis Long after Rhinoplasty with Silicone

Directory of Open Access Journals (Sweden)

Yuki Honda

2014-12-01

Full Text Available Rhinoplasty is a plastic surgery procedure to reconstruct the nose. Silicone alloplastic materials are most widely used as implants for rhinoplasty, but calcification on the surface occurs with long-term usage. Herein, we report a case of gruel-like calcification approximately 50 years after silicone implant rhinoplasty. In this case, calcification on the silicone surface might have transformed into gruel-like deposits, which presented as a subcutaneous mass at the dorsal area of the nose. The precise mechanism is unclear; a pH change in the tissue might have occurred during the process of inflammation, leading to the dissolution of calcified deposits.

2009-01-01

Familial tumoral calcinosis is characterized by ectopic calcifications and hyperphosphatemia. The disease is caused by inactivating mutations in fibroblast growth factor 23 (FGF23), Klotho (KL), and uridine diphosphate-N-acetyl-α-D-galactosamine:polypeptide N-acetylgalactosaminyltransferase 3 (GALNT3). In vitro studies indicate that GALNT3 O-glycosylates a phosphaturic hormone, FGF23, and prevents its proteolytic processing, thereby allowing secretion of intact FGF23. In this study we generat...

Thibierge-Weissenbach-Syndrome

Energy Technology Data Exchange (ETDEWEB)

Kulke, H.; Schweisfurth, H.; Auer, I.O.; Braun, H.

1982-03-01

Progressive systemic sclerosis is a generalized disorder of connective tissue. Subcutaneous calcifications are localized chiefly in volar aspects of the terminal phalanges of the fingers and along the extensor surface of the forearms and in the olecranon bursae. The association between subcutaneous calcinosis and scleroderma has been known as the Thibierge-Weissenbach-Syndrome. Two cases of this disease are reported. Differential diagnostic aspects of roentgenological findings are characterized and discussed.

Pulsed vs. CW low level light therapy on osteoarticular signs and symptoms in limited scleroderma (CREST syndrome)

Barolet, Daniel

2012-03-01

Limited cutaneous systemic sclerosis (lcSSc) was formerly known as CREST syndrome in reference to the associated clinical features: Calcinosis, Raynaud's phenomenon, Esophageal dysfunction, Sclerodactyly, and Telangiectasias. The transforming growth factor beta (TGF-β) has been identified has a major player in the pathogenic process, while low level light therapy (LLLT) has been shown to modulate this cytokine superfamily. This case study was conducted to assess the efficacy of 940nm using microsecond domain pulsing and continuous wave mode (CW) on osteoarticular signs and symptoms associated with lcSSc. The patient was treated two to three times a week for 13 weeks, using a sequential pulsing mode on one elbow, and a CW mode on the other. Efficacy assessments included inflammation, symptoms, pain, and health scales, patient satisfaction, clinical global impression, and adverse effects monitoring. Significant functional and morphologic improvements were observed after LLLT, with best results seen with the pulsing mode. No significant adverse effects were noted. Two mechanisms of action may be at play. The 940nm wavelength provides inside-out heating possibly vasodilating capillaries which in turn increases catabolic processes leading to a reduction of in situ calcinosis. LLLT may also improve symptoms by triggering a cascade of cellular reactions, including the modulation of inflammatory mediators.

Full Text Available Chronic kidney disease causes skin changes which may sometimes be the first sign of kidney failure. Specific skin changes include acquired perforating dermatosis, porphyria cutanea tarda, pseudoporphyria, calcinosis and nephrogenic systemic fibrosis. The majority of patients present with cutaneous manifestations which are classified as non-specific, including xerosis, pruritus, pigmentation disturbances, nail plate abnormalities, uraemic frost and gynaecomastia. Treatment improving kidney function (dialysis therapy or kidney transplantation also leads to the resolution of skin lesions.

Radiographic changes of the distal phalangeal tuft of the hands in subjects with systemic sclerosis. Systematic review.

Izquierdo, Yojhan Edilberto; Calvo Páramo, Enrique; Castañeda, Luisa María; Gómez, Sandra Viviana; Zambrano, Fernán Santiago

To determine abnormal plain radiograph findings of the distal phalanx tuft of the hand (DPTH) associated with systemic sclerosis in adults. A systematic review was developed following the parameters of the PRISMA guidelines in databases: MEDLINE, EMBASE, BIREME, Scielo, Google Scholar and others including as primary outcomes alterations of DPTH (erosions, resorption, sclerosis and proliferation) detected by simple radiography in subjects with systemic sclerosis. The prevalence of radiographic findings was synthesized using the fixed effects model. The statistical associations were expressed in terms of relative risk or odds ratio with their respective confidence intervals and p values. Twenty-two observational studies were included; the prevalence of DPTH resorption was 28.3% (95% CI: 0.256-0.312; p < .001); I 2 =80.4%, the prevalence of calcinosis was 15.6% (95% CI: 0.113-0.210; p < .001); I 2 =0%. No study reported proliferation or erosions and only one study described sclerosis of DPTH in 5 individuals. Resorption and calcinosis of DPTH are the characteristic radiographic findings in patients with systemic sclerosis. However, new studies with greater methodological strength are needed to establish associations between these phenomena and their presence in other connective tissue diseases.

Familial tumoral calcinosis is characterized by ectopic calcifications and hyperphosphatemia. The disease is caused by inactivating mutations in fibroblast growth factor 23 (FGF23), Klotho (KL), and uridine diphosphate-N-acetyl-alpha-D-galactosamine:polypeptide N-acetylgalactosaminyltransferase 3 (GALNT3). In vitro studies indicate that GALNT3 O-glycosylates a phosphaturic hormone, FGF23, and prevents its proteolytic processing, thereby allowing secretion of intact FGF23. In this study we generated mice lacking the Galnt3 gene, which developed hyperphosphatemia without apparent calcifications. In response to hyperphosphatemia, Galnt3-deficient mice had markedly increased Fgf23 expression in bone. However, compared with wild-type and heterozygous littermates, homozygous mice had only about half of circulating intact Fgf23 levels and higher levels of C-terminal Fgf23 fragments in bone. Galnt3-deficient mice also exhibited an inappropriately normal 1,25-dihydroxyvitamin D level and decreased alkaline phosphatase activity. Furthermore, renal expression of sodium-phosphate cotransporters and Kl were elevated in Galnt3-deficient mice. Interestingly, there were sex-specific phenotypes; only Galnt3-deficient males showed growth retardation, infertility, and significantly increased bone mineral density. In summary, ablation of Galnt3 impaired secretion of intact Fgf23, leading to decreased circulating Fgf23 and hyperphosphatemia, despite increased Fgf23 expression. Our findings indicate that Galnt3-deficient mice have a biochemical phenotype of tumoral calcinosis and provide in vivo evidence that Galnt3 plays an essential role in proper secretion of Fgf23 in mice.

The enzootic calcinosis is a disease produced in the bovines by the ingestion of the toxic plant Sg, which contains vitamine D 3 glycosides and its active metabolites. This disease is characterized by the loss of weight and physical condition, motor disorders and alteration of phosphocalcic metabolism with deposition of calcium compounds in soft tissues. To contribute to the advanced diagnostic of the disease, analytic techniques to determine D vitamine, D vitamine 25 (OH) and D vitamine 1,25 (OH) 2 in plasma, by high resolution liquid chromatography and radio receptor essay are used

Canine multiple cartilaginous exostoses: unusual manifestations and a review of the literature

International Nuclear Information System (INIS)

Jacobson, L.S.; Kirberger, R.M.

1996-01-01

Multiple cartilaginous exostoses were diagnosed in a two-year-old Great Dane and a four-month-old border collie. Clinically, the Great Dane showed only mild discomfort, while the border collie exhibited tetraparesis due to cervicothoracic compression. Unusual features in the Great Dane were exostoses that bridged physes, with progression after skeletal maturity. The border collie puppy's exostoses resembled tumoral calcinosis radiographically. Limb exostoses in this puppy often were para-articular, and most were not attached to the underlying bone. These features resembled metachondromatosis in humans. Analysis of previously reported cases of multiple cartilaginous exostoses indicated that the prognosis is guarded to poor

Sonographic findings in primary diseases of renal pyramids

Rao, B.K.

1987-01-01

Primary pathologic processes involving the renal pyramids such as papillary necrosis, drug-induced necrosis or calcinosis, cysts, neoplasms, and medullary nephrocalcinosis are rare. Thirty-four patients with primary renal pyramid diseases underwent US evaluation for altered morphology; a 5-MHz transducer was used. In 20 patients site-specific changes in the pyramid (e.g., papillary necrosis at the apex, small cysts at the base in medullary cystic disease, tubular calcification in MSK, corticomedullary hyperechogenicity in oxalosis) were noted on US. Sonographic delineation of the site and pattern of pathologic changes in the renal pyramid may help to identify specific diseases

Full Text Available In the period from 1991 to 2001 there were four patients followed up who suffered from cystinuria and cystine calcinosis. The therapy consisting of the cystine dilution in the urine by a great taking-in of liquids and the urine alkalization was combined with alphamercaptopropione glycine and captoprile that bind cystine as well as a respective diet. Alphamercaptopropione glycine leads to the reduction of the already-formed calculus and their easier treatment in the case of a possible need for extracorporeal lithotripsy (ESWEL. During the ten-year follow-up of a small series of patients there were no complications related to the medicament treatment.

Possibilities of radiologic diagnosis of pancreatic calcinosis and chronic calculous pancreatics

Loginov, A.S.; Sivash, Eh.S.; Kudryavtseva, G.V.

1982-01-01

X-ray diagnosis of the pancreatic gland calculous damage as well as chronic pancreatitis have been studied in 23 patients. A methodologic approach to examination of this group of patients was defined. Posteroanterior radiography has been shown to be of decisive importance in diagnosis of the calcified pancreatic gland. Duodenography and choleduodenography both considerably promote recognition of chronic pancreatitis. The radiologic method also allows one to reveal a series of complications: the common bile duct compression, duodenal stenosis, pancreatic tumor in the presence of chronic pancreatitis, malabsorption syndrome

Full Text Available BACKGROUND Our aim was to study the clinical and immunological profile of patients with newly detected connective tissue disease presented to a tertiary care centre. MATERIALS AND METHODS The study involved 51 patients with newly-detected Systemic Lupus Erythematosus (SLE (fulfilling the revise SLICC criteria for SLE and Systemic Sclerosis (SS, Mixed Connective Tissue Disease (MCTD, etc. attending Sir. T. Hospital, Bhavnagar, between January 2013 and December 2016. All patients were assessed for clinical features and immunological profile. RESULTS Out of the 51 patients, 30 having SLE, 10 having SS, 9 with MCTD, 1 with dermatomyositis and 1 with Rowell’s syndrome. Among them, 47 were females and 4 were males. The mean age at presentation was between 15-25 years. The LE-specific skin lesions were noted as malar rash in 25 patients (83%, subacute and acute lupus rashes (80% and discoid rash (13%. Among LE-nonspecific lesions, non-scarring alopecia was most common followed by oral ulcers, Raynaud’s phenomenon, joint pain, scarring alopecia, erythema multiforme, livedo reticularis, vasculitic lesions, urticaria and calcinosis cutis were seen. In MCTD, muscle weakness was common finding. In systemic sclerosis, hide-bound skin and decreases mouth opening were seen in all cases and Raynaud’s phenomenon, joint pain, hair loss, calcinosis cutis and respiratory system involvement were other features. Serum ANA was positive in 76% while negative in 3.8% of individuals. The most common pattern observed in ANA profile was speckled (56% followed by homogenous (32% and nucleolar (28%. CONCLUSION There is diversity in clinical presentation of autoimmune connective tissue disease with regards to their genetic and environmental backgrounds. Cutaneous features are utmost important having diagnostic and prognostic value as well.

Hypoparathyroidism Causing Seizures: When Epilepsy Does Not Fit

2018-01-01

Full Text Available A 24-year-old man presented to the Chris Hani Baragwanath Academic Hospital emergency department with recurrent seizures having previously been diagnosed with epilepsy from age 14. The biochemical investigations and brain imaging were suggestive of seizures secondary to hypocalcemia, and a diagnosis of idiopathic hypoparathyroidism was confirmed. After calcium and vitamin D replacement, the patient recovered well and is seizure free, and off antiepileptic therapy. This case highlights the occurrence of brain calcinosis in idiopathic hypoparathyroidism; the occurrence of acute symptomatic seizures due to provoking factors other than epilepsy; and the importance, in the correct clinical setting, of considering alternative, and sometimes treatable, causes of seizures other than epilepsy.

X-ray picture of the heart turn in echocardiographic diagnosis of rheumatic heart disease

International Nuclear Information System (INIS)

Grishkevich, A.M.; Goryanina, N.K.

1986-01-01

The paper is concerned with X-ray and echocardiographic investigation of the heart in 461 patients with mitral-tricuspidal disease. In 377 (82%) cases a turn of the heart along the longitudinal axis (counter clockwise) to the left and back was revealed. X-ray recognition of the heart turn made it possible to set an echocardiographic sensor to spot some of the cardiac cavities, interventricular septum and valvular apparatus. The correct setting of the echocardiographic sensor resulted in the determination of true sizes of each cardiac cavity, diagnosis of the nature of each valvular lesion and the recognition of such complications of rheumatic heart diseases as valvular calcinosis, left atrial thrombosis and disorder of myocardial contractility

Excretory calcinosis: a new fatal disease of wild American lobsters Homarus americanus.

Dove, Alistair D M; LoBue, Carl; Bowser, Paul; Powell, Mark

2004-03-10

A significant number of moribund and dead lobsters Homarus americanus were reported to New York state authorities by lobster fishers in Long Island Sound (LIS) during the summer of 2002. Morbid lobsters were characterised by an orange discolouration of the abdomen, lethargy, an excess of epibionts and poor post-capture survival. On necropsy, severe extensive multifocal or diffuse mineralised granulomatous inflammation of the gills and antennal glands was the most striking pathology. In the gills, granulomas often occluded the lumen of filaments, resulting in congestion, ischemia and coagulative necrosis of gill tissues. In the antennal glands, granulomas were concentrated along the border between the coelomosac and labyrinth. No significant pathogens were recovered from diseased individuals. In prechronic individuals, however, it was evident that granulomas were focused around calcium carbonate (aragonite) crystals. This disease may result from anomalously high sea-bottom temperatures in LIS (approximately 23 degrees C) during the summer of 2002 and associated disruptions of the calcium chemistry of lobsters in favour of deposition of minerals in soft tissues. The ultimate cause of death of affected lobsters is probably respiratory failure due to reduced effective surface area of the gills, exacerbated by hypermetabolic temperatures and an abundance of epibionts.

2011-01-01

A 10-week old male Hovawart presented with acute renal failure. Based on clinical symptoms, blood analysis results and serology, a diagnosis of leptospirosis was made. Besides being acotemic, the puppy was initially also severely hypercalcemic. The dog was treated successfully, but developed widespread cutaneous and visceral calcifications. Severe pyloric calcification resulted in functional pyloric obstruction, which was successfully treated by pyloromyotomy. All skin lesions were cured with topical therapy within a few weeks. To the authors' knowledge, this is the first report of generalized intestinal and cutaneous calcification associated with acute renal failure due to Leptospirosis.

Terje Forslund M.D., Ph.D.

2008-01-01

Full Text Available We present a patient who had ingested sodium bicarbonate for treatment of alcoholic dyspepsia during forty years at increasing doses. During the last year he had used more than 50 grams daily. He presented with metabolic alkalosis, epileptic convulsions, subdural hematoma, hypertension and rhabdomyolysis with end stage renal failure, for which he had to be given regular intermittent hemodialysis treatment. Untreated hypertension and glomerulonephritis was probably present prior to all these acute incidents. Examination of the kidney biopsy revealed mesangial proliferative glomerulonephritis and arterial wall thickening causing nephrosclerosis together with interstitial calcinosis. The combination of all these pathologic changes might be responsible for the development of progressive chronic renal failure ending up with the need for continuous intermittent hemodialysis treatment.

Fedorov, V.V.; Chantseva, E.A.

1992-01-01

Of 259 hemophiliacs bone pseudotumors were diagnosed in 11 (4.3 %); they were localised in the femur (6 cases), calcaneus (4) and in the iliac bone (3). Two cases of combined fermoral and calcaneal lesions and 4 cases of bone fracture were observed. As a rule, pseudotumors developed in hemophiliacs with severe disease. An x-ray picture of a pseudotumor depended on its site and was characterized by a large soft tissue tumor shadow, often with calcinosis, and serious destructive changes in bones in the form or round foci of 7 cm in diameter with clear-cut contours. An adge defect of the cortical layer was defined in the diaphysis of the femoral bone (15 cm long). Destructive changes were often accompanied by osteosclerosis and periostitis

Full Text Available We report a case of pituitary-dependent hyperadrenocorticism in a 10-year-old, female, terrier dog. The animal was admitted due to polyphagia, weight gain, polyuria, polydipsia, hair loss, exercise intolerance and panting at rest. On physical examination, abdominal distention, truncal and bilaterally symmetric alopecia, thin hypotonic skin, comedones, bruising, hyperpigmentation and calcinosis cutis on the dorsal midline were observed. Hematologic investigations showed stress leukogram, high serum alkaline phosphatase activity, mild to moderate alanine aminotransferase activity, hypercholesterolemia, hypertriglyceridemia and hyperglycemia. Mild generalized interstitial lung patterns and hepatomegaly were detected in the radiographs. Bilaterally symmetric normal-sized adrenal glands were also diagnosed in ultrasonography. Diagnosis of pituitary-dependent hyperadrenocorticism was confirmed with low-dose dexamethasone suppression test. The dog was successfully treated with mitotane.

Genetic rescue of glycosylation-deficient Fgf23 in the Galnt3 knockout mouse.

2014-10-01

Fibroblast growth factor 23 (FGF23) is a hormone that inhibits renal phosphate reabsorption and 1,25-dihydroxyvitamin D biosynthesis. The FGF23 subtilisin-like proprotein convertase recognition sequence ((176)RHTR(179)↓) is protected by O-glycosylation through ppGalNAc-T3 (GALNT3) activity. Thus, inactivating GALNT3 mutations render FGF23 susceptible to proteolysis, thereby reducing circulating intact hormone levels and leading to hyperphosphatemic familial tumoral calcinosis. To further delineate the role of glycosylation in the Fgf23 function, we generated an inducible FGF23 transgenic mouse expressing human mutant FGF23 (R176Q and R179Q) found in patients with autosomal dominant hypophosphatemic rickets (ADHR) and bred this animal to Galnt3 knockout mice, a model of familial tumoral calcinosis. Due to the low intact Fgf23 level, Galnt3 knockout mice with wild-type Fgf23 alleles were hyperphosphatemic. In contrast, carriers of the mutant FGF23 transgene, regardless of Galnt3 mutation status, had significantly higher serum intact FGF23, resulting in severe hypophosphatemia. Importantly, serum phosphorus and FGF23 were comparable between transgenic mice with or without normal Galnt3 alleles. To determine whether the presence of the ADHR mutation could improve biochemical and skeletal abnormalities in Galnt3-null mice, these mice were also mated to Fgf23 knock-in mice, carrying heterozygous or homozygous R176Q ADHR Fgf23 mutations. The knock-in mice with functional Galnt3 had normal Fgf23 but were slightly hypophosphatemic. The stabilized Fgf23 ADHR allele reversed the Galnt3-null phenotype and normalized total Fgf23, serum phosphorus, and bone Fgf23 mRNA. However, the skeletal phenotype was unaffected. In summary, these data demonstrate that O-glycosylation by ppGaINAc-T3 is only necessary for proper secretion of intact Fgf23 and, once secreted, does not affect Fgf23 function. Furthermore, the more stable Fgf23 ADHR mutant protein could normalize serum phosphorus

The confluence of several chronic conditions--in particular ageing, peripheral artery disease, diabetes, and chronic kidney disease--has created a global wave of lower limbs at risk for major amputation. While frequently asymptomatic or not lifestyle limiting, at least 1% of the population has peripheral artery disease of sufficient severity to be limb threatening. To avoid the critical error of failing to diagnose ischaemia, all patients with diabetic foot ulcers and gangrene should routinely undergo physiologic evaluation of foot perfusion. Ankle brachial index is useful when measurable, but may be falsely elevated or not obtainable in as many as 30% of patients with diabetic foot ulcers primarily because of medial calcinosis. Toe pressures and skin perfusion pressures are applicable to such patients. Copyright © 2016 John Wiley & Sons, Ltd.

A Systematic Study of Site-specific GalNAc-type O-Glycosylation Modulating Proprotein Convertase Processing

DEFF Research Database (Denmark)

Schjoldager, Katrine Ter-Borch Gram; Vester-Christensen, Malene B.; Goth, Christoffer K.

2011-01-01

Site-specific GalNAc-type O-glycosylation is emerging as an important co-regulator of proprotein convertase (PC) processing of proteins. PC processing is crucial in regulating many fundamental biological pathways and O-glycans in or immediately adjacent to processing sites may affect recognition...... and function of PCs. Thus, we previously demonstrated that deficiency in site-specific O-glycosylation in a PC site of the fibroblast growth factor, FGF23, resulted in marked reduction in secretion of active unprocessed FGF23, which cause familial tumoral calcinosis and hyperostosis hyperphosphatemia. GalNAc......-type O-glycosylation is found on serine and threonine amino acids and up to 20 distinct polypeptide GalNAc transferases catalyze the first addition of GalNAc to proteins making this step the most complex and differentially regulated steps in protein glycosylation. There is no reliable prediction model...

Fibroblast Growth Factor 23 (FGF23 and Disorders of Phosphate Metabolism

Full Text Available Derangements in serum phosphate level result in rickets/osteomalacia or ectopic calcification indicating that healthy people without these abnormalities maintain serum phosphate within certain ranges. These results indicate that there must be a regulatory mechanism of serum phosphate level. Fibroblast growth factor 23 (FGF23 was identified as the last member of FGF family. FGF23 is produced by bone and reduces serum phosphate level by suppressing phosphate reabsorption in proximal tubules and intestinal phosphate absorption through lowering 1,25-dihydroxyvitamin D level. It has been shown that excess and deficient actions of FGF23 result in hypophosphatemic rickets/osteomalacia and hyperphosphatemic tumoral calcinosis, respectively. These results indicate that FGF23 works as a hormone, and several disorders of phosphate metabolism can be viewed as endocrine diseases. It may become possible to treat patients with abnormal phosphate metabolism by pharmacologically modifying the activity of FGF23.

We report an unusual case of chronic mesenteric ischemia presenting in a 12-year-old girl with idiopathic infantile arterial calcinosis (IIAC). This is the first reported case in the literature of chronic mesenteric ischemia in the setting of IIAC. The girl presented with a classical history of postprandial abdominal pain. Imaging demonstrated significant stenoses of the celiac axis, superior mesenteric artery (SMA) and inferior mesenteric artery (IMA). Angioplasty of the celiac axis and SMA was attempted, with successful dilation of the SMA only. At 3-, 6- and 12-month follow-ups, the child's symptoms had almost resolved. This case report has three important ramifications: chronic mesenteric ischemia is a possible clinical presentation in children with IACC, pre-angioplasty imaging is important in guiding treatment approach, and angioplasty was effective in this case of chronic mesenteric ischemia and offers hope for other similarly affected children.

We review the imaging appearance of connective tissue diseases of the head and neck. Bilateral sialadenitis and dacryoadenitis are seen in Sjögren’s syndrome; ankylosis of the temporo-mandibular joint with sclerosis of the crico-arytenoid joint are reported in rheumatoid arthritis and lupus panniculitis with atypical infection are reported in patients with systemic lupus erythematosus. Relapsing polychondritis shows subglottic stenosis, prominent ear and saddle nose; progressive systemic sclerosis shows osteolysis of the mandible, fibrosis of the masseter muscle with calcinosis of the subcutaneous tissue and dermatomyositis/polymyositis shows condylar erosions and autoimmune thyroiditis. Vascular thrombosis is reported in antiphospholipid antibodies syndrome; cervical lymphadenopathy is seen in adult-onset Still’s disease, and neuropathy with thyroiditis reported in mixed connective tissue disorder. Imaging is important to detect associated malignancy with connective tissue disorders. Correlation of the imaging findings with demographic data and clinical findings are important for the diagnosis of connective tissue disorders. PMID:26988082

Cryoglobulinemic vasculitis is a rare entity. Although it has been reported in diffuse systemic sclerosis, it has not been reported in calcinosis, Raynaud's phenomenon, esophageal dysmotility, sclerodactyly and telangiectasia (CREST) syndrome. We report a patient with cryoglobulinemic vasculitis with CREST syndrome who did not have typical clinical features of vasculitis. This 58-year-old woman presented with mild generalized weakness and a diagnosis of CREST syndrome, which included Raynaud's syndrome, dysphagia and telangiectasias. She was positive for serum cryoglobulins, which led to a sural nerve biopsy. The biopsy results were consistent with cryoglobulinemic vasculitis. Cryoglobulinemic vasculitis has not been previously reported in CREST syndrome to our knowledge. Additionally, the patient also had limited clinical symptoms. Our patient displays the importance of checking for cryoglobulins and obtaining a nerve biopsy when the serum is positive. Both of these diagnostic tests were integral for directing appropriate treatment for this patient. Copyright © 2014 Elsevier Ltd. All rights reserved.

Mönckeberg sclerosis is a disease of unknown etiology, characterized by dystrophic calcification within the arterial tunica media of the lower extremities leading to reduced arterial compliance. Medial calcinosis does not obstruct the lumina of the arteries, and therefore does not lead to symptoms or signs of limb or organ ischemia. Mönckeberg sclerosis most commonly occurs in aged and diabetic individuals and in patients on dialysis. Mönckeberg arteriosclerosis is frequently observed in the visceral arteries, and it can occur in the head and neck region as well. This report describes a remarkable case of Mönckeberg arteriosclerosis in the head and neck region as detected on dental imaging studies. To the best of our knowledge, this is the first case that has been reported in which this condition presented in the facial vasculature. The aim of this report was to define the radiographic characteristics of Mönckeberg arteriosclerosis in an effort to assist health care providers in diagnosing and managing this condition

Full Text Available Nicola Ughi, Chiara Crotti, Francesca Ingegnoli Division of Rheumatology, Department of Clinical Sciences and Community Health, Gaetano Pini Institute, The University of Milan, Milan, Italy Abstract: Digital ulcers (DUs are a severe and frequent clinical feature of patients with systemic sclerosis (SSc. The presence of DUs may cause severe pain and often lead to impairment of patient’s functional activities and health-related quality of life. Moreover, poor patient cooperation during the wound care procedure due to pain may be associated with a negative outcome of DU healing. Therefore, pain management has a key role in patients with SSc. These two case reports describe the effectiveness and safety of oxycodone/naloxone in patients with SSc complicated by painful chronic DUs. Such a therapy has provided pain relief and consequently an increased compliance during redressing wounds.

Skin ulcers (SU) are one of the most frequent manifestations of systemic sclerosis (SSc). SSc-SU are very painful, often persistent and recurrent; they may lead to marked impairment of patient's activities and quality of life. Despite their severe impact on the whole SSc patient's management, the proposed definition, classification criteria, and therapeutic strategies of SSc-SU are still controversial. The present study aimed to elaborate a comprehensive proposal of definition, classification, and therapeutic strategy of SSc-SU on the basis of our long-term single center experience along with a careful revision of the world literature on the same topic. A series of 282 SSc patients (254 females and 28 males; 84% with limited and 16% diffuse cutaneous SSc; mean age of 51.5±13.9SD at SSc onset; mean follow-up 5.8±4.6SDyears) enrolled during the last decade at our Rheumatology Unit were retrospectively evaluated with specific attention to SSc-SU. The SSc-SU were classified in 5 subtypes according to prominent pathogenetic mechanism(s) and localization, namely 1. digital ulcers (DU) of the hands or feet, 2. SU on bony prominence, 3. SU on calcinosis, 4. SU of lower limbs, and 5. DU presenting with gangrene. This latter is a very harmful evolution of both DU of the hands and feet needing a differential diagnosis with critical limb ischemia. During the follow up period, one or more episodes of SSc-SU were recorded in over half patients (156/282, 55%); skin lesions were often recurrent and difficult-to-heal because of local complications, mainly infections (67.3%), in some cases associated to osteomyelitis (19.2%), gangrene (16%), and/or amputation (11.5%). SSc-SU were significantly associated with lower patients' mean age at the disease onset (p=0.024), male gender (p=0.03), diffuse cutaneous subset (p=0.015), calcinosis (p=0.002), telangiectasia (p=0.008), melanodermia (pTIME (necrotic Tissue, Infection/Inflammation, Moisture balance, and Epithelization).

Systemic sclerosis is a rare disease that predominantly affects women. The Medsger severity scale has been used to assess the severity, but it requires expensive and poorly accessible studies and it does not include complications such acrosteolysis, calcinosis, pericardial disease or hypothyroidism that occur on a relatively frequent basis in this disease. There is no study that considers if comorbidities, such as primary biliary cirrhosis, are related to gravity. To determine the correlation between severity and the presence of such complications. 40 patients with systemic sclerosis, dividing them into tertiles according to severity were studied. Dichotomous variables were described using percentages, while dimensional by averages+SD. Statistical inference was performed using chi square test or Kruskal-Wallis test with Dunn post-test, as appropriate. A significance at P<.05 was set. Of all the complications studied there were only differences in severity with acrosteolysis. Within comorbidities, primary biliary cirrhosis is not associated with gravity.

Case presentation A 54-year-old male patient with CREST syndrome presented with colicky postprandial pain of the upper abdomen, diminished food uptake and a 6-Kg-body weight loss during the previous 2 months. An ulcerative lesion in the third portion of the duodenum was revealed during duodenoscopy, with a diagnosis of adenocarcinoma on biopsy specimen histology. The patient underwent a partial pancreatoduodenectomy. No adjuvant therapy was instituted and follow-up is negative for local recurrence or metastases 21 months postoperatively. Conclusion CREST syndrome has been associated with colon cancer, gastric polyps, familial adenomatous polyposis (FAP syndrome and Crohn's disease; however, this is the first report of a primary adenocarcinoma of the duodenum in a patient with CREST syndrome. However, any etiologic relationship remains to be further investigated.

Pulsed versus continuous wave low-level light therapy on osteoarticular signs and symptoms in limited scleroderma (CREST syndrome): a case report

2014-11-01

Limited cutaneous systemic sclerosis (lcSSc) was formerly known as CREST syndrome in reference to the associated clinical features: calcinosis, Raynaud's phenomenon, esophageal dysfunction, sclerodactyly, and telangiectasias. The transforming growth factor beta has been identified as a major player in the pathogenic process, where low-level light therapy (LLLT) has been shown to modulate this cytokine superfamily. This case study was conducted to assess the efficacy of 940 nm using millisecond pulsing and continuous wave (CW) modes on osteoarticular signs and symptoms associated with lcSSc. The patient was treated two to three times a week for 13 weeks using a sequential pulsing mode on one elbow and a CW mode on the other. Efficacy assessments included inflammation, symptoms, pain, health scales, patient satisfaction, clinical global impression, and adverse effects monitoring. Considerable functional and morphologic improvements were observed after LLLT, with the best results seen with the pulsing mode. No adverse effects were noted. Pulsed LLLT represents a treatment alternative for osteoarticular signs and symptoms in limited scleroderma (CREST syndrome).

Does nailfold capillaroscopy help predict future outcomes in systemic sclerosis? A systematic literature review.

Science.gov (United States)

Paxton, Dolcie; Pauling, John D

2018-02-14

Nailfold capillaroscopy (NC) is an important diagnostic tool in systemic sclerosis (SSc). Confirmation of NC as a prognostic factor could facilitate earlier intervention and slow disease progression in SSc. We undertook a systematic literature review to evaluate the prognostic value of NC in predicting SSc disease progression. Standardised searches of EMBASE and MEDLINE were undertaken to identify longitudinal studies of adult subjects with SSc reporting the prognostic value of NC for any aspect of disease progression and/or survival. Non-English, non-original research, animal studies, non-adult studies and non-full length reports were excluded from the analysis (PROSPERO 2017:CRD42017071719). Wide heterogeneity in study design, prognostic factor measurement and study outcomes necessitated a qualitative data synthesis. The "QUality In Prognosis Studies" (QUIPS) risk-of-bias tool was used to assess study quality. Study selection, data extraction and risk-of-bias assessment were each undertaken independently by 2 reviewers and consensus reached where necessary. Of 942 retrieved articles, 18 studies fulfilled the inclusion criteria. The majority of studies (17/18, 94%) reported positive associations between baseline NC appearances (using a variety of qualitative, semi-quantitative and quantitative NC endpoints) and clinical outcomes including digital ulcer (DU) occurrence/healing, survival, disease progression (using domains of Medsger disease severity scale), calcinosis, skin progression, pulmonary arterial hypertension (PAH), and/or a composite analysis of "cardiovascular events". Application of the QUIPS tool identified a moderate-high risk of potential bias in 6/18 studies for study participation, 3/18 studies for study attrition, 10/18 for prognostic factor measurement, 5/18 for outcome measurement, 13/18 for confounders and 13/18 for statistical analyses. Study quality limited the strength of the conclusions drawn from these studies. The most important source of

The purpose of this study was to assess the sonographic morphology of the clinical and subclinical pathology of facial acne vulgaris. We studied patients with facial acne vulgaris diagnosed by certified dermatologists, and using a standardized protocol for sonographic examinations, we sequentially described the sonographic pathomorphologic characteristics. Lesions of particular interest to the referring clinician were also analyzed separately. Additionally, acne involvement was staged clinically and sonographically (SOS-Acne) using morphologic definitions of the relevant lesions and predefined scoring systems for gradation of the severity of acne lesions. A total of 245 acne lesions in 20 consecutive patients were studied. Sonographic abnormalities consisted of pseudocysts, folliculitis, fistulas, and calcinosis. Most conditions were subclinical and mostly due to lesion extensions deep into the dermis and hypodermis (52% of pseudocysts and 68% of fistulas). The statistical concordance between acne severity scores assigned by two separate clinicians was strong (κ = 0.8020), but the corresponding sonographic scores generally showed more severe and clinically occult involvement. Facial acne vulgaris often involves deeper tissues, beyond the reach of the spatially restricted clinical examination; these subclinical conditions can be detected and defined with sonography. Additionally, acne vulgaris is amenable to sonographic scoring.

We performed thallium 201 muscle scans to assess muscular involvement in 40 patients with different connective tissue diseases (7 with dermatomyositis, 7 with systemic lupus erythematosus, 12 with progressive systemic scleroderma, 2 with calcinosis, Raynaud's phenomenon, esophageal involvement, sclerodactyly, and telangiectasia (CREST) syndrome, 3 with monomelic scleroderma, 6 with morphea, and 3 with Raynaud's disease). Only 12 of these patients complained of fatigability and/or myalgia. Electromyography was performed and serum levels of muscle enzymes were measured in all patients. Comparison of thallium 201 exercise recording with the other tests revealed that scan sensitivity is greater than electromyographic and serum muscle enzymes levels. Thallium 201 scans showed abnormal findings in 32 patients and revealed subclinical lesions in 18 patients, while electromyography findings were abnormal in 25 of these 32 patients. Serum enzyme levels were raised in only 8 patients. Thallium 201 scanning proved to be a useful guide for modifying therapy when laboratory data were conflicting. It was useful to evaluate treatment efficacy. Because our data indicate a 100% positive predictive value, we believe that thallium 201 scanning should be advised for severe systemic connective tissue diseases with discordant test results

According to previous studies in captive cheetah ( Acinonyx jubatus ) populations, one of the most threatening diseases besides amyloidosis, myelopathy, veno occlusive disease, and gastritis, is renal failure. Contrary to captive cheetahs in North America and South Africa, morphological data concerning renal lesions in the cheetah European Endangered Species Program (EEP) are lacking. This study details the histological characterization as well as immunohistochemical and morphometrical analysis of nephropathies in 35 captive cheetahs from the EEP, which were necropsied between 1985 and 2003. Examination of paraffin- and glycolmethacrylate-methylmethacrylate (GMA-MMA) embedded kidney samples by light microscopy revealed glomerulonephritis in 91%, with a high prevalence for glomerulosclerosis and glomerulonephritis with the histologic pattern of membranous glomerulonephritis (77%). Besides these predominating glomerulopathies, a wide range of other renal lesions, like acute tubular necrosis, interstitial nephritis, calcinosis, and amyloidosis, were present. Pathological expression of collagen type IV, complement C3, fibronectin, and IgG was demonstrated in the glomeruli of the cheetah kidneys with the use of the avidin-biotin complex method. Morphometrical analysis was performed on GMA-MMA embedded kidney samples to obtain glomerulosclerosis index and glomerulosclerosis incidence.

Full Text Available Automated abnormal brain detection is extremely of importance for clinical diagnosis. Over last decades numerous methods had been presented. In this paper, we proposed a novel hybrid system to classify a given MR brain image as either normal or abnormal. The proposed method first employed digital wavelet transform to extract features then used principal component analysis (PCA to reduce the feature space. Afterwards, we constructed a kernel support vector machine (KSVM with RBF kernel, using particle swarm optimization (PSO to optimize the parameters C and σ. Fivefold cross-validation was utilized to avoid overfitting. In the experimental procedure, we created a 90 images dataset brain downloaded from Harvard Medical School website. The abnormal brain MR images consist of the following diseases: glioma, metastatic adenocarcinoma, metastatic bronchogenic carcinoma, meningioma, sarcoma, Alzheimer, Huntington, motor neuron disease, cerebral calcinosis, Pick’s disease, Alzheimer plus visual agnosia, multiple sclerosis, AIDS dementia, Lyme encephalopathy, herpes encephalitis, Creutzfeld-Jakob disease, and cerebral toxoplasmosis. The 5-folded cross-validation classification results showed that our method achieved 97.78% classification accuracy, higher than 86.22% by BP-NN and 91.33% by RBF-NN. For the parameter selection, we compared PSO with those of random selection method. The results showed that the PSO is more effective to build optimal KSVM.

The aim of this study was to illustrate the risk of vocal fold atrophy in patients who receive serial subepithelial steroid injections for vocal fold scar. This study is a retrospective case report of two patients who underwent a series of weekly subepithelial infusions of 10 mg/mL dexamethasone for benign vocal fold lesion. Shortly after the procedures, both patients developed a weak and breathy voice. The first patient was a 53-year-old man with radiation-induced vocal fold stiffness. Six injections were performed unilaterally, and 1 week later, he developed unilateral vocal fold atrophy with new glottal insufficiency. The second patient was a 67-year-old woman with severe vocal fold inflammation related to laryngitis and calcinosis, Raynaud's phenomenon, esophagean dysmotility, sclerodactyly, and telangiectasia (CREST) syndrome. Five injections were performed bilaterally, and 1 week later, she developed bilateral vocal fold atrophy with a large midline glottal gap during phonation. In both cases, the steroid-induced vocal atrophy resolved spontaneously after 4 months. Serial subepithelial steroid infusions of the vocal folds, although safe in the majority of patients, carry the risk of causing temporary vocal fold atrophy when given at short intervals.

Full Text Available Objective: It was aimed to identify skin findings those were seen in patients who undergone renal transplantation. Methods: Patients who have been followed in Erciyes University Nephrology Hospital renal transplantation outpatient clinic were included in the study. They were evaluated for dermatologic findings during routine controls. Age, gender, transplantation date, identity of organ donor, history of medications, dermatological history and dermatological findings during examination were recorded. Biopsy was performed when needed. Results: In total 94 patients, 25 female (26.6% and 69 male (73.4%, were recruited to the study. Mean age was 36±10 years. The most frequent skin finding was drug-related acne (n=20. Most common infectious disease was verruca (n=17. There were viral disease other than verruca such as herpes zoster (n=3, superficial mycosis such as onychomycosis (n=5, tinea versicolor, tinea pedis and bacterial skin disease (n=2, and paronychia (n=1 and pre-malign lesions such as actinic cheilitis and bowenoid papulosis. Besides these, stria (n=3, kserosis (n=2, cornu cutaneum, café-au-lait spots, sebaceous hyperplasia and seborrheic dermatitis, skin tag, hypertrichosis, unguis incarinatus and calcinosis were other skin findings those were seen. No malign skin lesion was observed in any of patients. Conclusion: Miscellaneous skin lesions should develop in patients those undergone renal transplantation due to long-term utilization of various immunosuppressive drugs.

The fibroblast growth factor receptors (FGFR) play a major role in angiogenesis and are desirable targets for the development of therapeutics. Groups of Wistar Han rats were dosed orally once daily for 4 days with a small molecule pan-FGFR inhibitor (5mg/kg) or once daily for 6 days with a small molecule MEK inhibitor (3mg/kg). Serum phosphorous and FGF23 levels increased in all rats during the course of the study. Histologically, rats dosed with either drug exhibited multifocal, multiorgan soft tissue mineralization. Expression levels of the sodium phosphate transporter Npt2a and the vitamin D-metabolizing enzymes Cyp24a1 and Cyp27b1 were modulated in kidneys of animals dosed with the pan-FGFR inhibitor. Both inhibitors decreased ERK phosphorylation in the kidneys and inhibited FGF23-induced ERK phosphorylation in vitro in a dose-dependent manner. A separate cardiovascular outcome study was performed to monitor hemodynamics and cardiac structure and function of telemetered rats dosed with either the pan-FGFR inhibitor or MEK inhibitor for 3 days. Both compounds increased blood pressure (~+ 17 mmHg), decreased heart rate (~-75 bpm), and modulated echocardiography parameters. Our data suggest that inhibition of FGFR signaling following administration of either pan-FGFR inhibitor or MEK inhibitor interferes with the FGF23 pathway, predisposing animals to hyperphosphatemia and a tumoral calcinosis-like syndrome in rodents.

Scleroderma is a fairly rare connective tissue disease whose autoantibody profile is associated with different clinical manifestations. The prevalence of autoantibodies in scleroderma is influenced by race and genetics. To study the prevalence of anti-Scl-70, anti-centromere (ACA) and anti-U1-RNP antibodies in patients with scleroderma in southern Brazil and verify their association with clinical manifestations of the disease. A retrospective study involving 66 patients with scleroderma for the presence of anti-Scl-70, anti-centromere and anti-U1-RNP and of clinical manifestations such as Raynaud's phenomenon, digital micro scars, digital necrosis, telangiectasias, calcinosis, pulmonary fibrosis, pleuritis, pericarditis, cardiomyopathy, arthralgia and arthritis, skin sclerosis, joint contractures, tendon friction rubs, pulmonary hypertension, esophageal disorders and renal crisis. The prevalence of anti-Scl-70 was 17.8% , that of ACA was 33.3% and the prevalence of U1 RNP was 11.8%. Anti-Scl-70 was associated with the diffuse form of the disease (p = 0.015), presence of cardiomyopathies (p = 0.016) and digital micro scars (p = 0.05). Anti-centromere was more common in the limited form, although it was not statistically significant, and had a protective role associated with cardiomyopathies (p = 0.005). Anti-U1-RNP was more common in the overlap forms (p = 0.0004). The prevalence and profile of clinical associations of autoantibodies in Brazilian patients with scleroderma are similar to those found in the literature.

Sensitive and specific criteria for the classification of systemic sclerosis are required by clinicians and investigators to achieve higher quality clinical studies and approaches to therapy. A clinical study of systemic sclerosis patients in Europe and Canada led to a set of criteria that achieve high sensitivity and specificity. Both clinical and laboratory investigations of patients with systemic sclerosis, related conditions and diseases with clinical features that can be mistaken as part of the systemic sclerosis spectrum were undertaken. Laboratory investigations included the detection of autoantibodies to centromere proteins, Scl-70 (topoisomerase I), and fibrillarin (U3-RNP). Based on the investigation of 269 systemic sclerosis patients and 720 patients presenting with related and confounding conditions, the following set of criteria for the classification of systemic sclerosis was proposed: 1) autoantibodies to: centromere proteins, Scl-70 (topo I), fibrillarin; 2) bibasilar pulmonary fibrosis; 3) contractures of the digital joints or prayer sign; 4) dermal thickening proximal to the wrists; 5) calcinosis cutis; 6) Raynaud's phenomenon; 7) esophageal distal hypomotility or reflux-esophagitis; 8) sclerodactyly or non-pitting digital edema; 9) teleangiectasias. The classification of definite SSc requires at least three of the above criteria. Criteria for the classification of systemic sclerosis have been proposed. Preliminary testing has defined the sensitivity and specificity of these criteria as high as 99% and 100%, respectively. Testing and validation of the proposed criteria by other clinical centers is required.

Aims: Quantitative ultrasound (QUS) of the calcaneus is being frequently used to screen for osteoporosis. This technique correlates very well with dual-energy X-ray absorptiometry (DXA) of the spine and femur, and predicts fracture risk in postmenopausal women. The correlation between QUS and DXA in premenopausal women with prevalent vitamin D deficiency however is not known. We assessed the correlation between both techniques in 55 pre- and postmenopausal Arabian women, a population with high prevalence of vitamin D deficiency. Methods: BMD of the right calcaneus was estimated by Sahara ultrasound (Hologic, Waltham, MA). Spine and right total femur BMD was determined by DXA scan (Lunar Expert XL, Madison, WI). Results: Overall, the correlation between calcaneal BMD estimated by QUS and spine and femur BMD measured by DXA in pre- and postmenopausal United Arab Emirates women was statistically significant (r=0.41; p=0.002 for spine and r=0.44; p=0.001 for femur, respectively). In postmenopausal women, all correlations between DXA and QUS parameters were statistically significant. In contrast, only BUA and SOS correlated significantly with spine BMD in premenopausal women. Conclusion: The correlation between DXA and QUS is statistically significant in postmenopausal United Arab Emirates women. However, this correlation is much weaker in premenopausal UAE women suggesting that other factors such as vitamin D deficiency may influence this correlation

Calciphylaxis and Martorell Hypertensive Ischemic Leg Ulcer: Same Pattern - One Pathophysiology.

2016-01-01

This review presents a closer look at four diseases which are probably closely related to one another pathophysiologically: (a) calciphylaxis (distal pattern); (b) calciphylaxis (proximal pattern); (c) Martorell hypertensive ischemic leg ulcer; (d) calciphylaxis with normal renal and parathyroid function (synonym: eutrophication). The four diseases have largely the same risk factors: (1) arterial hypertension, (2) diabetes mellitus (types 1 and 2), (3) secondary or tertiary hyperparathyroidism (in end-stage kidney disease) and (4) oral anticoagulation with vitamin K antagonists. They share the same clinical patterns: necrotizing livedo, skin infarctions at typical locations and acral gangrene in calciphylaxis. They also share the same histopathology: ischemic subcutaneous arteriolosclerosis and small-artery disease and 'miniaturizing' Mönckeberg medial calcinosis. The treatment concept for the acute phase of the diseases is also broadly similar. In addition to an optimized control of the cardiovascular risk factors, a proactive wound approach (necrosectomy, negative pressure wound treatment with vacuum dressings, and early skin grafts supported by systemic antibiotic therapy) leads most rapidly and effectively to a reduction of the initially severe wound pain, and finally to complete healing of the wound. Oral anticoagulation with vitamin K antagonists should be stopped. In extensive cases, the use of intravenous sodium thiosulfate is recommended. All four diagnoses are little known in the medical schools of most countries. The need to improve familiarity with these four closely related disorders is therefore great. In particular, the risk of confusion with pyoderma gangrenosum is a major diagnostic problem which can lead to false and even damaging treatment. © 2016 S. Karger AG, Basel.

Dermatomyositis (DM) patients typically present with proximal weakness and autoantibodies that are associated with distinct clinical phenotypes. We observed that DM patients with autoantibodies recognizing the nuclear matrix protein NXP-2 often presented with especially severe weakness. The aim of this study was to characterize the clinical features associated with anti-NXP-2 autoantibodies. There were 235 DM patients who underwent testing for anti-NXP-2 autoantibodies. Patient characteristics, including muscle strength, were compared between those with and without these autoantibodies. The number of cancer cases observed in anti-NXP-2-positive subjects was compared with the number expected in the general population. Of the DM patients, 56 (23.8%) were anti-NXP-2-positive. There was no significant difference in the prevalence of proximal extremity weakness in patients with and without anti-NXP-2. In contrast, anti-NXP-2-positive patients had more prevalent weakness in the distal arms (35% versus 20%; P = 0.02), distal legs (25% versus 8%; P edema (36% versus 19%; P = 0.01) than anti-NXP-2-negative patients. Five anti-NXP-2-positive subjects (9%) had cancer-associated myositis, representing a 3.68-fold increased risk (95% confidence interval 1.2-8.6) compared to the expected prevalence in the general population. In DM, anti-NXP-2 autoantibodies are associated with subcutaneous edema, calcinosis, and a muscle phenotype characterized by myalgia, proximal and distal weakness, and dysphagia. As anti-NXP-2-positive patients have an increased risk of cancer, we suggest that they undergo comprehensive cancer screening. © 2017, American College of Rheumatology.

Hyperostosis-hyperphosphatemia syndrome (HHS) is a rare metabolic disorder characterized by hyperphosphatemia and localized hyperostosis. HHS is caused by mutations in GALNT3, which encodes UDP-N-acetyl-alpha-D-galactosamine:polypeptide N- acetylgalactosaminyltransferase 3. Familial tumoral calcinosis (TC), characterized by ectopic calcifications and hyperphosphatemia, is caused by mutations in the GALNT3 or fibroblast growth factor 23 (FGF23) genes. Our objective was to identify mutations in FGF23 or GALNT3 and determine serum FGF23 levels in an HHS patient. Mutation detection in FGF23 and GALNT3 was performed by DNA sequencing, and serum FGF23 concentrations were measured by ELISA. A 5-year-old French boy with HHS and his family members participated. The patient presented with painful cortical lesions in his leg. Radiographs of the affected bone showed diaphyseal hyperostosis. The lesional tissue comprised trabeculae of immature, woven bone surrounded by fibrous tissue. Biochemistry revealed elevated phosphate, tubular maximum rate for phosphate reabsorption per deciliter of glomerular filtrate, and 1,25-dihydroxyvitamin D levels. The patient was a compound heterozygote for two novel GALNT3 mutations. His parents and brother were heterozygous for one of the mutations and had no biochemical abnormalities. Intact FGF23 level in the patient was low normal, whereas C-terminal FGF23 was elevated, a pattern similar to TC. The presence of GALNT3 mutations and elevated C-terminal, but low intact serum FGF23, levels in HHS resemble those seen in TC, suggesting that HHS and TC are different manifestations of the same disorder. The absence of biochemical abnormalities in the heterozygous individuals suggests that one normal allele is sufficient for secretion of intact FGF23.

Mutations in the dentin matrix protein 1 (DMP1) gene cause autosomal recessive hypophosphatemic rickets (ARHR). Hypophosphatemia in ARHR results from increased circulating levels of the phosphaturic hormone, fibroblast growth factor 23 (FGF23). Similarly, elevated FGF23, caused by mutations in the PHEX gene, is responsible for the hypophosphatemia in X-linked hypophosphatemic rickets (XLH). Previously, we demonstrated that a Phex mutation in mice creates a lower set point for extracellular phosphate, where an increment in phosphorus further stimulates Fgf23 production to maintain low serum phosphorus levels. To test the presence of the similar set point defect in ARHR, we generated 4- and 12-week-old Dmp1/Galnt3 double knockout mice and controls, including Dmp1 knockout mice (a murine model of ARHR), Galnt3 knockout mice (a murine model of familial tumoral calcinosis), and phenotypically normal double heterozygous mice. Galnt3 knockout mice had increased proteolytic cleavage of Fgf23, leading to low circulating intact Fgf23 levels with consequent hyperphosphatemia. In contrast, Dmp1 knockout mice had little Fgf23 cleavage and increased femoral Fgf23 expression, resulting in hypophosphatemia and low femoral bone mineral density (BMD). However, introduction of the Galnt3 null allele to Dmp1 knockout mice resulted in a significant increase in serum phosphorus and normalization of BMD. This increased serum phosphorus was accompanied by markedly elevated Fgf23 expression and circulating Fgf23 levels, an attempt to reduce serum phosphorus in the face of improving phosphorus levels. These data indicate that a Dmp1 mutation creates a lower set point for extracellular phosphate and maintains it through the regulation of Fgf23 cleavage and expression. PMID:28005411

Mutations in the PHEX gene cause X-linked hypophosphatemia (XLH). Hypophosphatemia in XLH results from increased circulating levels of a phosphaturic hormone, fibroblast growth factor 23 (FGF23), which inhibits renal phosphate reabsorption and 1,25-dihydroxyvitamin D (calcitriol) synthesis. The current standard therapy for XLH--high-dose phosphate and calcitriol--further increases FGF23 concentrations, suggesting that patients with XLH may have an altered response to extracellular phosphate. To test for the presence of abnormal phosphate responsiveness, we compared serum biochemistries and femoral Fgf23 mRNA expression between wild-type mice, murine models of XLH (Phex(K496X)) and hyperphosphatemic tumoral calcinosis (Galnt3(-/-)), and Galnt3/Phex double-mutant mice. Phex mutant mice had not only increased Fgf23 expression but also reduced proteolytic cleavage of intact Fgf23 protein, resulting in markedly elevated intact Fgf23 levels and consequent hypophosphatemia. In contrast, despite markedly increased Fgf23 expression, Galnt3 knockout mice had significantly high proteolytic cleavage of Fgf23 protein, leading to low intact Fgf23 concentrations and hyperphosphatemia. Galnt3/Phex double-mutant mice had an intermediate biochemical phenotype between wild-type and Phex mutant mice, including slightly elevated intact Fgf23 concentrations with milder hypophosphatemia. Despite the hypophosphatemia, double-mutant mice attempted to reduce serum phosphate back to the level of Phex mutant mice by upregulating Fgf23 expression as much as 24-fold higher than Phex mutant mice. These data suggest that Phex mutations alter the responsiveness of bone cells to extracellular phosphate concentrations and may create a lower set point for "normal" phosphate levels.

Experiments were performed to observe the influence of x-ray irradiation on mast cells and mastocalcergy in rats. Animals were irradiated single dose of x-ray. X-ray irradiation was applied to the whole body in doses either 100 rads or 150 rads (Cobalt-60 Teletherapy Unit). One day after irradiation the rats were injected lead acetate intravenously, followed by injection of compound 48/80 in the back subcutaneously. Animals were killed by decapitation at intervals, 1 hour, 5 hours, 1 day and 6 day after subcutaneous injection. Specimens of the abdominal and back skin were fixed in alcohol formol solution and stained with the following methods; H-E for observation of pathological changes of tissues, toluidine blue for demonstration of mast cells, von Kossa-azure A for demonstration of carbonate and phosphate, and chloranilic acid for demonstration of calcium. The following conclusions were obtained. Calciphylatic wheals are large size in the control group, medium size in 100 rads irradiation group and small size in 150 rads irradiation group. In x-ray irradiation groups the number of mast cells decreases more in the 150 rads than in the 100 rads irradiation. In the 100 rads x-ray irradiation group, histochemical study of the injection sites showed that calcium impregnated to mast cell granules and connective tissue fibers in 1 days after subcutaneous injection. The morphogenesis of this calcinosis was the same in the rat of 5 hour after subcutaneous injection of the control group. Whereas, 1 day after subcutaneous injection in 150 rads x-ray irradiation group calcium deposited more slightly than other groups.

Full Text Available Dermatomyositis (DM is a chronic inflammatory disorder of the skin and muscles. Evidence supports that DM is an immune-mediated disease and 50-70% of patients have circulating myositis-specific auto-antibodies. Gene expression microarrays have demonstrated upregulation of interferon signaling in the muscle, blood, and skin of DM patients. Patients with classic DM typically present with symmetric, proximal muscle weakness, and skin lesions that demonstrate interface dermatitis on histopathology. Evaluation for muscle inflammation can include muscle enzymes, electromyogram, magnetic resonance imaging, and/or muscle biopsy. Classic skin manifestations of DM include the heliotrope rash, Gottron′s papules, Gottron′s sign, the V-sign, and shawl sign. Additional cutaneous lesions frequently observed in DM patients include periungual telangiectasias, cuticular overgrowth, "mechanic′s hands", palmar papules overlying joint creases, poikiloderma, and calcinosis. Clinically amyopathic DM is a term used to describe patients who have classic cutaneous manifestations for more than 6 months, but no muscle weakness or elevation in muscle enzymes. Interstitial lung disease can affect 35-40% of patients with inflammatory myopathies and is often associated with the presence of an antisynthetase antibody. Other clinical manifestations that can occur in patients with DM include dysphagia, dysphonia, myalgias, Raynaud phenomenon, fevers, weight loss, fatigue, and a nonerosive inflammatory polyarthritis. Patients with DM have a three to eight times increased risk for developing an associated malignancy compared with the general population, and therefore all patients with DM should be evaluated at the time of diagnosis for the presence of an associated malignancy. This review summarizes the immunopathogenesis, clinical manifestations, and evaluation of patients with DM.

The aims of the study were to determine prognostic factors for survival and causes of death in a cohort of patients with systemic sclerosis (SSc). This was a cohort study of SSc patients in single rheumatologic center from January 1998 to August 2012. They fulfilled the American College of Rheumatology classification criteria for SSc or had calcinosis Raynaud's phenomenon, esophageal dysmotility, sclerodactyly, telangiectasia or sine sclerosis. Causes of death were classified as SSc related and non-SSc related. Kaplan-Meier and Cox proportional hazard regression models were used in univariate and multivariate analysis to analyse survival in subgroups and determine prognostic factors of survival. The study includes 220 patients (192 female, 28 male). Out of thirty-two (14.5 %) who died, seventeen (53.1 %) deaths were SSc related and in nine (28.1 %) non-SSc-related causes, and in six (18.8 %) of patients causes of death were not defined. Overall survival rate was 92.6 % (95 % CI 87.5-95.7 %) after 5 years and 82.3 % (95 % CI 73.4-88.4 %) after 10 years. Pulmonary involvement was a major SSc-related cause of death, occurred in seven (41.1 %) patients. Cardiovascular events were leading cause of in overall death (11) 34.3 % and 6 in non-SSc-related death. Independent risk factors for mortality were age >50 at diagnosis (HR 5.10) advance pulmonary fibrosis (HR 11.5), tendon friction rub at entry (HR 6.39), arthritis (HR 3.56). In this first Middle Eastern series of SSc registry, pulmonary and cardiac involvements were the leading cause of SSc-related death.

Full Text Available Background: Systemic sclerosis (SSc is a multisystem connective tissue disorder of uncertain etiology. The clinical picture is frequently dominated by prominent cutaneous manifestations that have diagnostic and prognostic significance. The objective of the present study was to find out the demographic profile and the relative frequencies and characteristics of different mucocutaneous features of SSc in a group of patients from eastern India. In addition, we sought to compare the frequency and pattern of the findings in the limited versus the diffuse variety of the disease. Materials and Methods:This was a cross-sectional, clinical observational study. Consecutive patients of SSc attending the dermatology O.P.D. of a tertiary care hospital of eastern India over 3 years were enrolled to the present study. Results:A total of 46 patients (41 females and 5 males; mean age 29.6±12.3 years of SSc were evaluated. Among mucocutaneous manifestations Raynaud′s phenomenon was present in 39 (84.8% patients. Other cutaneous features included dyspigmentation (40, 86.9%, sclerodactyly (38, 82.6%, inability to open the mouth (38,82.6%, mat-like telangiectasia (11,23.1%, fingertip ulceration and scarring (29,63%, cutaneous calcinosis (1,2.2%, digital gangrene in (2,4.3%, generalized pruritus (4,8.7%, cutaneous small vessel vasculitis (2,4.3%, chronic urticaria (2,4.3%, flexion contractures of the fingers (13,28.3%, and amputation of the digits (3,6.5%. Mucosal changes were observed in 10 (21.7% patients and nail changes were seen in 13 (28.2% patients. Diffuse cutaneous SSc was noted in 27 (58.7% patients and limited cutaneous SSc was seen in the remainder. Thirty-six (78.2% patients tested positive for ANA. Conclusion: The present study provides a snapshot of the spectrum of the demographic and mucocutaneous manifestations of SSc in the eastern Indian population. We have not observed any statistically significant differences between dcSSc and lcSSc in terms

METHODS: A retrospective study involving 66 patients with scleroderma for the presence of anti-Scl-70, anti-centromere and anti-U1-RNP and of clinical manifestations such as Raynaud's phenomenon, digital micro scars, digital necrosis, telangiectasias, calcinosis, pulmonary fibrosis, pleuritis, pericarditis, cardiomyopathy, arthralgia and arthritis, skin sclerosis, joint contractures, tendon friction rubs, pulmonary hypertension, esophageal disorders and renal crisis. RESULTS: The prevalence of anti-Scl-70 was 17.8% , that of ACA was 33.3% and the prevalence of U1 RNP was 11.8%. Anti-Scl-70 was associated with the diffuse form of the disease (p = 0.015, presence of cardiomyopathies (p = 0.016 and digital micro scars (p = 0.05. Anti-centromere was more common in the limited form, although it was not statistically significant, and had a protective role associated with cardiomyopathies (p = 0.005. Anti-U1-RNP was more common in the overlap forms (p = 0.0004. CONCLUSION: The prevalence and profile of clinical associations of autoantibodies in Brazilian patients with scleroderma are similar to those found in the literature.

Dermatomyositis (DM) is a major clinical subset of autoimmune myositis (AIM). The characteristic DM rash (Gottron papules, heliotrope rash) and perifascicular atrophy at skeletal muscle biopsy are regarded as specific features for this diagnosis. However, new concepts are challenging the current definition of DM. A modified Bohan and Peter classification of AIM was proposed in which the core concept was the inclusion of the diagnostic significance of overlap connective tissue disease features. In this clinical classification, a DM rash in association with myositis in the absence of overlap features indicates a diagnosis of pure DM. However, overlap features in association with myositis allow a diagnosis of overlap myositis (OM), irrespective of the presence or absence of the DM rash. Perifascicular atrophy may be present in both pure DM and OM. Recently, the presence of perifascicular atrophy in myositis without a DM rash was proposed as diagnostic of a novel entity, adermatopathic DM. We conducted the present study to evaluate these new concepts to further differentiate pure DM from OM.Using the modified Bohan and Peter classification, we performed a follow-up study of a longitudinal cohort of 100 consecutive adult French Canadian patients with AIM, including 44 patients with a DM phenotype, defined as a DM rash, and/or DM-type calcinosis, and/or the presence of perifascicular atrophy on muscle biopsy. A detailed evaluation was performed for overlap features, the extent and natural history of the DM rash, adermatopathic DM, DM-specific and overlap autoantibodies by protein A immunoprecipitation on coded serum samples, and associations with cancer and survival.Two distinct subsets were identified in patients with a DM phenotype: pure DM (n = 24) and OM with DM features, or OMDM (n = 20). In pure DM, the DM rash was a dominant finding. It was the first disease manifestation, was always present at the time of myositis diagnosis, and was associated with a high

Full Text Available Solanum glaucophyllum (Sg [= S. malacoxylon] is a calcinogenic plant inducing "Enzootic Calcinosis" in cattle. The 1,25-dihydroxyvitamin D3, its main toxic principle, regulates bone and calcium metabolism and also exerts immunomodulatory effects. Thymocyte precursors from bone marrow-derived progenitor cells differentiate into mature T-cells. Differentiation of most T lymphocytes is characterized not only by the variable expression of CD4/CD8 receptor molecules and increased surface density of the T cell antigen receptor, but also by changes in the glycosylation pattern of cell surface glycolipids or glycoproteins. Thymocytes exert a feedback influence on thymic non-lymphoid cells. Sg-induced modifications on cattle thymus T-lymphocytes and on non-lymphoid cells were analysed. Heifers were divided into 5 groups (control, intoxicated with Sg during 15, 30 or 60 days, and probably recovered group. Histochemical, immunohistochemical, lectinhistochemical and morphometric techniques were used to characterize different cell populations of the experimental heifers. Sg-poisoned heifers showed a progressive cortical atrophy that was characterized using the peanut agglutinin (PNA lectin that recognizes immature thymocytes. These animals also increased the amount of non-lymphoid cells per unit area detected with the Picrosirius technique, WGA and DBA lectins, and pancytokeratin and S-100 antibodies. The thymus atrophy found in intoxicated animals resembled that of the physiological aging process. A reversal effect on these changes was observed after suppression of the intoxication. These findings suggest that Sg-intoxication induces either directly, through the 1,25-dihydroxyvitamin D3 itself, or indirectly through the hypercalcemia, the observed alteration of the thymus.Solanum glaucophyllum (Sg [= S. malacoxylon] é uma planta calcinogênica que induz "Calcinose Enzoótica" em bovinos.
