The continuous turnover of BONE MATRIX and mineral that involves first an increase in BONE RESORPTION (osteoclastic activity) and later, reactive BONE FORMATION (osteoblastic activity). The process of bone remodeling takes place in the adult skeleton at discrete foci. The process ensures the mechanical integrity of the skeleton throughout life and plays an important role in calcium HOMEOSTASIS. An imbalance in the regulation of bone remodeling's two contrasting events, bone resorption and bone formation, results in many of the metabolic bone diseases, such as OSTEOPOROSIS.
A clinical syndrome associated with the retention of renal waste products or uremic toxins in the blood. It is usually the result of RENAL INSUFFICIENCY.

Strains of mice in which certain GENES of their GENOMES have been disrupted, or "knocked-out". To produce knockouts, using RECOMBINANT DNA technology, the normal DNA sequence of the gene being studied is altered to prevent synthesis of a normal gene product. Cloned cells in which this DNA alteration is successful are then injected into mouse EMBRYOS to produce chimeric mice. The chimeric mice are then bred to yield a strain in which all the cells of the mouse contain the disrupted gene. Knockout mice are used as EXPERIMENTAL ANIMAL MODELS for diseases (DISEASE MODELS, ANIMAL) and to clarify the functions of the genes.

Biochemical indices of osteomalacia in pregnant Asian immigrants in Britain. (1/293)

Serum calcium, phosphate and alkaline phosphatase, and urinary calcium excretion were examined during the second trimester of uncomplicated normal pregnancy in Asian immigrants to Britain and in local Caucasians. The mean serum calcium was significantly lower in Asians than in Caucasians, and the mean serum alkaline phosphatase was significantly higher in Asians. The geometric mean of the urinary calcium excretion was highly significantly lower in Asians than in Caucasians. The variances of the serum calcium, serum alkaline phosphatase, and urine calcium excretion did not differ significantly in the two populations. This indicates that there is a shift in values of immigrant Asians as a group compared with Caucasians. A comparison with figures obtained on normal nonpregnant persons of both suggests that the shift is not an inherent feature of the Asian population.  (+info)

Use of ultrasonography in the diagnosis of osteomalacia: preliminary results on experimental osteomalacia in the rat. (2/293)

This study was performed to investigate the ability of ultrasonographic technique to distinguish osteomalacia from normal bone with the same mineral content. Ten rats with experimentally induced osteomalacia (group A) and 12 control rats having similar body size and weight (group B) were studied. Histomorphometric analysis confirmed the presence of osteomalacia in two rats from group A and showed normally mineralized bone in two rats from group B. Whole body bone mineral density, measured by dual-energy x-ray absorptiometry, was similar in the two groups (86 +/- 6 mg/cm2 in group A and 89 +/- 4 mg/cm2 in group B). The velocity of the ultrasound beam in bone was measured by densitometer at the first caudal vertebra of each rat. The velocity was measured when the first peak of the waveform reached a predetermined minimum amplitude value (amplitude-dependent speed of sound) as well as at the lowest point of this curve before it reaches the predetermined minimum amplitude (first minimum speed of sound). Although the amplitude-dependent speed of sound was similar in the two groups (1381.9 +/- 11.8 m/s in group A and 1390.9 +/- 17.8 m/s in group B), the first minimum speed of sound was clearly different (1446.1 +/- 8.9 m/s in group A and 1503.3 +/- 10.9 m/s in group B; P < 0.001). This study shows that ultrasonography could be used to identify alterations in bone quality, such as osteomalacia, but further studies need to be carried out before this method can be introduced into clinical practice.  (+info)

Bone histology in patients with nephrotic syndrome and normal renal function. (3/293)

BACKGROUND: The prevalence of metabolic bone disease in patients with nephrotic syndrome (NS) at normal level of renal function remains uncertain. METHODS: To address this issue, we studied 30 patients (20 men and 10 women, mean age 27.3 +/- 11.7 years) with NS who had normal renal function (mean creatinine clearance 103 +/- 4 ml/min). We evaluated their serum calcium, phosphorus, alkaline phosphatase, immunoreactive parathyroid hormone (iPTH), vitamin D metabolites, urinary calcium, and skeletal survey. The extent of bone mineralization was analyzed by histomorphometric analysis of iliac crest bone biopsy specimens in all patients. The findings on bone histology were correlated with biochemical parameters. RESULTS: The mean duration of NS was 35.5 +/- 26.9 months, with a protein excretion of 7.3 +/- 3.2 g/24 hr and a serum albumin of 2.2 +/- 0.8 g/dl. Total serum calcium was 7.8 +/- 0.8 mg/dl, whereas ionized calcium was 5.7 +/- 0.7 mg/dl, phosphorus 3.2 +/- 1.2 mg/dl, and alkaline phosphatase 149 +/- 48.6 U/liter. Serum iPTH levels were normal in all except two patients. The mean serum 25-hydroxyvitamin D [25(OH)D] level was 3.9 +/- 1.2 ng/ml (normal 15 to 30 ng/ml), whereas 1,25-dihydroxyvitamin D was 24 +/- 4.7 pg/ml (normal 16 to 65). There was an inverse correlation between serum levels of 25(OH)D and the magnitude of proteinuria (r = -0.42, P < 0.05). The mean 24-hour urinary calcium excretion was 82 +/- 21 mg/day. The skeletal survey was normal in all patients. Bone histology was normal in 33.3% of the patients, whereas 56.7% had isolated osteomalacia (OSM), and 10% had an increased bone resorption in association with defective mineralization. The severity of OSM measured by mineralization lag time correlated linearly with the duration (r = 0.94, P < 0.0001) and the amount (r = 0.97, P < 0.0001) of proteinuria. All patients with NS for more than three years had histological changes. Patients with OSM had lower 25(OH)D and serum albumin as compared with those with normal histology (P < 0.005). Bone mineralization had no significant correlation with serum iPTH, divalent ions, or vitamin D levels. CONCLUSIONS: OSM is a frequent finding in adult patients with NS, even at a normal level of renal function. Its severity correlates with the amount and duration of proteinuria.  (+info)

Vitamin D supplementation, 25-hydroxyvitamin D concentrations, and safety. (4/293)

For adults, the 5-microg (200 IU) vitamin D recommended dietary allowance may prevent osteomalacia in the absence of sunlight, but more is needed to help prevent osteoporosis and secondary hyperparathyroidism. Other benefits of vitamin D supplementation are implicated epidemiologically: prevention of some cancers, osteoarthritis progression, multiple sclerosis, and hypertension. Total-body sun exposure easily provides the equivalent of 250 microg (10000 IU) vitamin D/d, suggesting that this is a physiologic limit. Sailors in US submarines are deprived of environmentally acquired vitamin D equivalent to 20-50 microg (800-2000 IU)/d. The assembled data from many vitamin D supplementation studies reveal a curve for vitamin D dose versus serum 25-hydroxyvitamin D [25(OH)D] response that is surprisingly flat up to 250 microg (10000 IU) vitamin D/d. To ensure that serum 25(OH)D concentrations exceed 100 nmol/L, a total vitamin D supply of 100 microg (4000 IU)/d is required. Except in those with conditions causing hypersensitivity, there is no evidence of adverse effects with serum 25(OH)D concentrations <140 nmol/L, which require a total vitamin D supply of 250 microg (10000 IU)/d to attain. Published cases of vitamin D toxicity with hypercalcemia, for which the 25(OH)D concentration and vitamin D dose are known, all involve intake of > or = 1000 microg (40000 IU)/d. Because vitamin D is potentially toxic, intake of >25 microg (1000 IU)/d has been avoided even though the weight of evidence shows that the currently accepted, no observed adverse effect limit of 50 microg (2000 IU)/d is too low by at least 5-fold.  (+info)

Is low plasma 25-(OH)vitamin D a major risk factor for hyperparathyroidism and Looser's zones independent of calcitriol? (5/293)

BACKGROUND: Recent reports suggest that calcitriol might not be the sole active metabolite of vitamin D and that plasma concentrations of 25-(OH)vitamin D (25OHD) are often abnormally low in hemodialysis patients. We have therefore evaluated plasma 25OHD as a risk factor for parathyroid hormone (PTH) hypersecretion and radiological bone disease. We carried out a cross-sectional study during the month of September in an Algerian dialysis center of 113 patients who were not taking supplements of alphacalcidol or calcitriol. METHODS: Plasma 25OHD, calcitriol, PTH, calcium, phosphate, bicarbonate, and aluminum were measured, and x-rays of the hands and pelvis were obtained for evaluation of subperiosteal resorption and Looser's zones. RESULTS: The median plasma 25OHD was 47.5 nmol/liter (range 2.5 to 170.0). Univariate analysis showed that plasma PTH was correlated positively with months on maintenance dialysis and negatively with plasma 25OHD, calcitriol, calcium, bicarbonate and aluminum, but not with that of phosphate. plasma 25OHD was positively correlated with calcium and calcitriol. Using multiple regression analysis, only plasma 25OHD (negative) and the duration on maintenance dialysis (positive) were independently linked to plasma PTH. The prevalence of isolated subperiosteal resorption (ISR) was 34%, and that of the combination of resorption with Looser's zones (CRLZ) was 9%; thus, only 57% of the patients had a normal x-ray appearance. These groups were comparable with regards to age, gender, and duration on dialysis. When the biochemical measurements of the patients with CRLZ were compared with those from patients without radiological lesions, plasma 25OHD was the only parameter to show a statistically significant difference, being significantly lower in the CRLZ group (26 +/- 18 vs. 57 nmol/liter, ANOVA, P < 0.004). Plasma 25OHD was also significantly lower in the ISR group (44, P < 0.05) than in the normal x-ray group, and plasma Ca (P < 0.003) and bicarbonate (P < 0.02) were lower. Logistical analysis showed that the presence of resorption was independently linked only with plasma PTH. Looser's zones and subperiosteal resorption were not seen in patients with plasma 25OHD of more than 40 (Looser's zones) and more than 100 nmol/liter (subperiosteal resorption). The optimal range for intact PTH in hemodialysis patients with mild aluminum overload is 10 to 25 pmol/liter. We found that plasma PTH was inappropriately high only when plasma 25OHD was less than 100 nmol/liter. With a plasma 25OHD of between 100 and 170 nmol/liter, hypercalcemia was present with a plasma PTH of less than 10 pmol/liter in only one case. CONCLUSIONS: This cross sectional study shows that low plasma 25OHD is a major risk factor for hyperparathyroidism and Looser's zones. In dialysis patients, we suggest that the plasma levels of 25OHD are maintained around the upper limit of the reference range of sunny countries.  (+info)

Bone scintigraphy in renal osteodystrophy. (6/293)

Bone scintigraphy with Tc-99m HEDP was performed in 30 patients on maintenance hemodialysis, and the results of quantitative analysis were compared with those of a normal group. To permit this comparison, elevated background activity due to the absence of renal radiotracer excretion was reduced by hemodialysis to levels found in the normals. Histologic proof of renal osteodystrophy had been obtained in all patients. The incidence of radiographic abnormalities was 46%, whereas abnormal scans were found in 25 patients (83%); skeletal lesions were also more pronounced and detected earlier. However, even when the scans appeared normal, the quantitative analysis showed increased skeletal activity in all patients. The total skeletal activity proved to be a good index of the severity of renal osteodystrophy and appeared dependent on both osteomalacia and hyperparathyroidism. These findings show that bone scintigraphy is a sensitive method to detect skeletal involvement in renal osteodystrophy.  (+info)

Increased bone strontium levels in hemodialysis patients with osteomalacia. (7/293)

BACKGROUND: In this study, we report on the association between increased bone strontium levels and the presence of osteomalacia in end-stage renal failure patients treated by hemodialysis. METHODS: We performed a histologic examination and determined the strontium content and strontium/calcium ratios in bone biopsies of 100 hemodialysis patients recruited from various centers all over the world. Aside from the bone strontium concentration, the bone aluminum content was assessed. The bone zinc concentration, a nonrelevant element for bone toxicity, was also measured. RESULTS: Bone strontium levels and bone strontium/calcium ratios were increased in subjects with osteomalacia when compared with those with the other types of renal osteodystrophy. Bone strontium and bone calcium levels correlated with each other. The slope of the linear regression curve correlating these parameters was much steeper in the osteomalacic group (Y = 2.22X - 120) as compared with the other types of renal osteodystrophy (Y = 0.52X - 5.7). Within the group of patients with osteomalacia, bone strontium levels also significantly correlated with the bone aluminum content (r = 0.72, P = 0.018). No such correlation was found for the other types of renal osteodystrophy. The bone zinc concentration of subjects with normal renal function did not differ significantly from the values noted for the various types of renal osteodystrophy taken as separate groups, nor could increased bone zinc concentrations be associated with a particular bone lesion. CONCLUSIONS: Our data demonstrate an association between osteomalacia and increased bone strontium concentrations in dialysis patients. Further studies are warranted to establish whether strontium plays either a primary, secondary, or contributive role in the development of the latter type of renal osteodystrophy.  (+info)

Use of quantitative ultrasonography in differentiating osteomalacia from osteoporosis: preliminary study. (8/293)

The aim of this work was to use ultrasonographic technology to differentiate osteoporosis from osteomalacia on the basis of different patterns of the graphic trace. Three patients with osteomalacia and three with osteoporosis, all with the same lumbar spine bone mineral density, were studied. The velocity of the ultrasound beam in bone was measured by a DBM Sonic 1,200/I densitometer at the proximal phalanges of the hands in all the patients. The ultrasound beam velocity was measured when the first peak of the waveform reached a predetermined minimum amplitude value (amplitude-dependent speed of sound) as well as at the lowest point prior to the first and second peaks, before they reached the predetermined minimum amplitude value (first and second minimum speeds of sound). The graphic traces were further analyzed by Fourier analysis, and both the main frequency (f0) and the width of the peak centered in the f0 (full width at half maximum) were measured. The first and second minimum speeds of sound were significantly lower in the patients with osteomalacia than in the osteoporosis group. The first minimum speed of sound was 2,169 +/- 73 m/s in osteoporosis and 1,983 +/- 61 m/s in osteomalacia (P < 0.0001); the second minimum peak speed of sound was 1,895 +/-59 m/s in osteoporosis and 1,748 +/- 38 m/s in osteomalacia (P < 0.0001). The f0 was similar in the two groups (osteoporosis, 0.85 +/- 0.14 MHz; osteomalacia, 0.9 +/- 0.22 MHz; P = 0.72), and the full width at half maximum was significantly higher in the osteomalacia patients (0.52 +/- 0.14 MHz) than in the osteoporosis patients (0.37 +/- 0.15 MHz) (P = 0.022). This study confirms that ultrasonography is a promising, noninvasive method that could be used to differentiate osteoporosis from osteomalacia, but further studies should be carried out before this method can be introduced into clinical practice.  (+info)

Clinical trial for Familial Hypophosphatemic Rickets , Study of Longitudinal Observation for Patient With X-linked Hypophosphatemic Rickets/Osteomalacia in Collaboration With Asian Partners
Tumor-induced osteomalacia (TIO) is a rare paraneoplastic syndrome characterized by severe hypophosphatemia and osteomalacia. Nonspecific symptoms make the diagnosis elusive. In addition, locating the responsible tumor(s) is challenging. The aim of this study was to investigate the clinical management and outcomes of TIO. The clinical features, diagnostic procedures, treatment, and outcomes of 12 patients were reviewed retrospectively. The cohort comprised six men and six women (mean age 45.5 ± 9.9 years, range 23-61 years). The mean duration of disease was 3.7 ± 2.6 years. All patients manifested progressive bone pain, muscle weakness, and/or difficulty walking. Serum phosphorus concentrations were low in all patients (mean 0.42 ± 0.12 mmol/L). Technetium-99m octreotide scintigraphy was performed in 11 patients and showed lesions in the right distal femur, left femoral head, and right tibial plateau, respectively, in three patients. Magnetic resonance imaging (MRI) was negative for lesions in one
1. A patient with familial adult-onset hypophosphataemia, whose myopathy was closely related to the plasma phosphate concentration, was investigated by phosphorus nuclear magnetic resonance spectroscopy (31P n.m.r.) in vivo of the right flexor digitorum superficialis muscle.. 2. During hypophosphataemia induced by stopping oral phosphate a significant reduction in measured muscle strength occurred, but the ratios of the intramyocellular levels of phosphocreatine (PCr), adenosine triphosphate (ATP) and inorganic phosphate (Pi) remained unchanged at rest. During exercise these levels changed, as did the intramyocellular pH, but they did not differ from the pattern previously recorded in normal subjects.. 3. In four adults with inherited infantile-onset hypophosphataemia (vitamin D-resistant rickets, VDRR) without myopathy, the n.m.r. measurements were normal at rest and during exercise.. 4. In one patient with inherited hyperphosphataemia (tumoral calcinosis) the resting PCr: Pi ratio was ...
Severe osteomalacia (confirmed by the examination of thin undecalcified bone biopsy sections) associated with hypophosphataemia developed in a 60 year old woman. A skeletal x-ray survey showed a lytic lesion in the right proximal femur, and this was curetted, showing a vascular tumour. The patients symptoms improved almost immediately and serum phosphate concentrations returned to normal. Some time later the syndrome and the tumour recurred. The tumour was excised, and again the patient improved. Morphological examination of the tumour showed a lesion which closely resembled haemangiopericytoma. Review of published reports confirmed that most reported cases have been associated with vascular mesenchymal tumours both in intraosseous and extraosseous sites.. ...

The syndrome of tumor-induced osteomalacia has been previously thought to occur only in association with mesenchymal tumors, although one report has linked prostatic carcinoma with the syndrome. We report the case of a patient who presented first with the clinical and biochemical features of the syndrome of inappropriate antidiuretic hormone secretion, and then oncogenic osteomalacia. The first syndrome was characterized by headaches, nausea, and vomiting; serum sodium determinations ranged between 107 and 118 meq/L with simultaneous urine spot sodium concentrations of 100 to 116 meq/L. The circulating antidiuretic hormone level was markedly elevated to 261.5 µU/mL. The osteomalacia was discovered incidentally when depressed serum phosphorus levels of 1.2 to 1.7 mg/dL were noted in association with 24-hour urine phosphorus excretion exceeding 1000 mg/24 h. Undecalcified tetracycline-labeled bone biopsy samples confirmed oncogenic osteomalacia. Only afterward was a small-cell carcinoma of the ...

DIAGNOSIS Phosphaturic Mesenchymal Tumor, Mixed Connective Tissue Variant (PMT-MCT). DISCUSSION. Osteomalacia is a bone disease characterized by gradual softening and bending of the bones due to inadequate mineralization of osteoid. The most common etiologies of osteomalacia include vitamin D deficiency and renal tubular dysfunction; however, in rare instances, osteomalacia can be associated with bone and soft tissue tumors as a paraneoplastic syndrome (i.e. oncogenic osteomalacia) (1, 4, 8). Though the mechanism behind the inadequate mineralization of osteoid in this setting is not entirely understood, it is hypothesized that tumor over-expression of FGF-23 may play a role. This protein appears to inhibit trans-epithelial phosphate transport in renal tubules, resulting in renal phosphate wasting and subsequent osteomalacia (2-4, 11). While a heterogeneous group of tumors may cause oncogenic osteomalacia, PMT-MCT is the most common (1, 6). Tumors associated with oncogenic osteomalacia are ...
en] We report the case of a patient with severe muscular and articular tenderness that caused almost complete immobility. This subject had severe hypophosphatemia due to hyperphosphaturia. Fibroblast growth factor 23 (FGF-23) was abnormally high and the diagnostic of tumor-induced osteomalacia was made. Despite multiple tests, the tumor was not localized. In this report, we discuss different possible investigations to localize the tumor. Lastly, we review the potential therapy available when tumor is not found and can thus not ...
For many years, the existence of phosphatonins-substances secreted by certain tumors which result in profound renal phosphorus wasting and resultant osteomalacia-has been postulated.. Evidence has recently been accumulating that fibroblast growth factor 23 (FGF-23) is the phosphatonin we have been searching for:. High circulating levels of FGF23 are associated with hypophosphatemia, decreased 1,25 (OH) vitamin D levels, and rickets/bone disease.. The disease autosomal dominant hypophosphatemic rickets is caused by gain-of-function mutations in FGF23caused by splice site mutations. Conversely, the genetic disease inherited tumoral calcinosis, characterized by hyperphosphatemia, increased 1,25 (OH) vitamin D levels, and metastatic calcifications.. In ESRD, FGF23 levels are appropriately elevated in response to hyperphosphatemia, but due to a reduced GFR is unable to induce adequate phosphaturia.. How it works at a molecular level: FGF23 interacts with FGF receptors at the proximal tubule, ...

Bone disease - Metabolic bone disease: The normal function of bone requires an adequate supply of amino acids (the building blocks for proteins) for the synthesis of collagen, the chief component of the organic matrix; of calcium and phosphate for mineralization of the organic matrix; and of other organic compounds and mineral elements. Also, growth, repair, and remodeling of the bone tissue require a precisely regulated supply of hormones, vitamins, and enzymes. Skeletal disease, when it is due to inadequacies in the supply or action of the above essentials, associated with abnormalities outside the skeleton, is termed metabolic; in such cases the entire skeleton is affected.

In November 2015, Jumana, a teenage patient, arrived at the NIH seeking a cure for a rare disease that made her bones so fragile and muscles so weak that she was confined to her bed, barely able to lift her legs. Earlier this year, after a medical collaboration by NIH researchers and others around the world, Jumana was cured and is able to walk again.. The patient, who traveled nearly 6,000 miles from her home in the Palestinian territories to the Clinical Center, had a disease called tumor-induced osteomalacia (TIO). TIO is caused by a rare endocrine tumor that secretes FGF23, a hormone that regulates phosphate absorption and active vitamin D production. In high levels, as is seen in TIO, it causes low blood phosphate levels that leads to muscle weakness, bone pain and fractures.. There are only a few places in the world with expertise in diagnosing and treating TIO. When clinicians in Israel diagnosed the condition in this patient, but couldnt find the tumor, they called Dr. Michael Collins, ...

Oncogenic osteomalacia, or tumour-induced osteomalacia (TIO), is a rare paraneoplastic syndrome characterised by hypophosphataemia, phosphaturia, inappropriately low serum levels of 1,25-dihydroxyvitamin D for hypophosphataemia. TIO is caused by mesenchymal tumours that secrete phosphaturic substances, leading to increased renal wasting of phosphates. These tumours are very small in size and grow slowly. Localisation of these tumours has always been difficult with the available biochemical and imaging techniques. At times, despite all efforts, the tumour could not be localised. We report our experience with a 42-year-old woman with TIO where whole-body magnetic resonance imaging could not localise the tumour, a scapular haemangiopericytoma. PET/CT was helpful in the localisation of the tumour which, when surgically removed, resulted in the normalisation of biochemical parameters with clinical improvement..

Phosphaturic mesenchymal tumor (PMT) represents a rare cause of osteomalacia. The clinical signs and symptoms are vague and these lead to diagnosis delay. In the presence of hypophosphatemia and relatively high urine phosphate excretion, this entity should be taken into consideration in the deferential diagnosis of osteomalacia. In the present article, we report 81-year-old man presented to our clinic for evaluation due to osteopenia. His laboratory results disclosed hypophosphatemia, relatively increased urine phosphate excretion and increased level of intact fibroblast growth factor 23 (FGF23). A 68Gallium DOTATATE PET/CT revealed pathological uptake in the upper aspect of the left shoulder adjacent to the coracoid process. For suspected PMT a wide resection of the tumor was performed and pathological findings were consistent for PMT. Laboratory tests were normalized postoperatively. Reviewing the literature, we had identified 33 reported cases of PMTs among elderly patients age ≥70 years. ...

I am a 60-year-old female with osteoporosis. I took Fosamax 70 mg once weekly for seven months until I could no longer endure the side effects. For the following month, I took no medication. Since January 21, 2008, I have been on 680 mg strontium citrate once daily. I intend to relate my progress. My first DEXA scan was done May 8, 2007. My T-score at the lumbar spine was -3.0 (-2.0 at L1, -2.7 at L2, -3.4 at L3 and -3.8 at L4). My T-score at the left hip was -2.2 (-2.8 at neck, -2.0 at troch, -1.9 at inter). My BMD results in g/cm2 were 0.712 at the spine (L1-L4), 0.53 at the left hip (neck), and 0.670 at the left hip (total). A followup scan is planned for July 6, 2009.

On biochemical analysis, DHAP-AT activity, a membrane bound peroxisomal enzyme involved in the first step of biogenesis of plasmalogen, was severely diminished in fibroblasts from patients F-01 and F-04 with ZS (6.5% and 10.6% of control fibroblasts), determined as described previously.6 On the other hand, fibroblasts from F-05 with IRD had residual DHAP-AT activity (26.1% of the control) (table 1). Concerning β oxidation activity of lignoceric acid relative to that of palmitic acid (C24:0/C16:0), IRD fibroblasts also had residual activity (19.2% of the control), as compared to findings in fibroblasts from patients F-01 and F-04 with ZS (4.4% and 5.9% of the control), determined as described previously7 (table 1).. Next, we investigated the relationship between gene mutation, protein import machinery, and the residual activities using gene transfection. The PEX2-wild,PEX2-R125X, andPEX2-E55K gene sequences subcloned into the expression vector pUcD2SRαMCS8 were transfected toPEX2 deficient CHO ...
Results Demographic and clinical characteristics of both groups are shown in Table 1. Of the 108 patients evaluated, the genetic test results of 39 patients are available at this moment (the rest of the results are currently pending). 59% (23/39) tested positive for the genetic mutation.Despite data are still partial and although the results did not achieve statistical significance, we observed with a greater relevance a higher proportion of patients with HPP presenting with chronic bone pain (48,7% vs 25,6%,p=0,157), muscle weakness (15,4% vs 2,6%, p=0,112) and more necessity of analgesic medication (p=0,107) in patients with HPP in comparison with the control group. Furthermore, there was a non-significant trend in the HPP-group to present dental abnormalities and premature dental loss (7,6%), absent manifestations in the control group (p=0,123). In addition, orthopedic surgery was more common in the HPP group (12,8%) compared with the other group (0%), p=0,04. The prevalence of stress ...

Renal osteodystrophy is currently defined as an alteration of bone morphology in patients with chronic kidney disease (CKD). It is one measure of the skeletal component of the systemic disorder of chronic kidney disease-mineral and bone disorder (CKD-MBD). The term renal osteodystrophy was coined in 1943, 60 years after an association was identified between bone disease and renal failure. The traditional types of renal osteodystrophy have been defined on the basis of turnover and mineralization as follows: mild, slight increase in turnover and normal mineralization; osteitis fibrosa, increased turnover and normal mineralization; osteomalacia, decreased turnover and abnormal mineralization; adynamic, decreased turnover and acellularity; mixed, increased turnover with abnormal mineralization. A Kidney Disease: Improving Global Outcomes report has suggested that bone biopsies in patients with CKD should be characterized by determining bone turnover, mineralization, and volume (TMV system). On the ...
In July, 2012, four researchers at Ryerson University in Toronto, Canada, published a study in Bone entitled: Monitoring bone strontium levels of an osteoporotic subject due to self-administration of strontium citrate with a novel diagnostic tool, in vivo XRF: a case study. This study is significant because it used a non-invasive method (not an invasive method, such as bone biopsy) to analyze the strontium levels of bones in an osteoporotic patient who began taking strontium citrate for the study. Therefore, it was possible to obtain her baseline bone strontium levels prior to initiation of therapy with strontium citrate. The researchers wrote: By 120 hours, the increase (in bone strontium level) was statistically significant at 0.68 ± 0.07 and 0.93 ± 0.05 (for the finger and ankle), respectively. Further increases occurred within an interval of 90-180 days, with the most recent, after 800 days, at the finger and ankle being 7 and 15 times higher than the initial baseline reading. The ...

If you could actually get under a ball and catch it, even if it bounced out of your glove, it counted. But the runner still got to stay on base. The only way you could actually be put out is if you knocked over someones beer.
