Abstract
Retroperitoneal paragangliomas are tumors of neuroectodermal origin rarely appearing in the pediatric population. We report a case of a large paraganglioma infiltrating the right kidney and inferior vena cava in a 16-year-old boy who initially presented with a right-sided varicocele. Right retroperitoneal paraganglioma was embolized preoperatively, followed by total tumor excision, right nephrectomy, inferior vena cava resection, and reconstruction using a prosthetic vascular graft. Retroperitoneal tumors requiring surgery can successfully be treated by radical resection and replacement of the inferior vena cava in experienced centers.

Abstract
Introduction: The use of complementary and alternative medicine (CAM) has become a customary practice among pediatric cancer patients worldwide. The frequency of its use by pediatric cancer patients in Croatia has not been previously determined. Methodology: In order to establish the frequency and detect factors affecting the use of CAM, a single-center, observational, cross-sectional study was conducted at the Children's Hospital Zagreb during a two-year period. The patients' parents and caregivers were offered an anonymous, multi-item questionnaire that collected socio-economic and clinical data, as well as details on CAM and dietary supplement practice. Results: Almost half of the participants reported CAM and more than two-thirds reported dietary supplement consumption, predominantly in the intensive phase of the treatment. Factors regarding children or parents had no effect on CAM and supplement utilization. Herbal medicine, vitamins, and minerals were among the most commonly used items. Every 10th child experienced at least one adverse event during CAM and supplement use. Conclusion: Awareness of the CAM and dietary supplement application in pediatric oncology patients needs to be raised due to the potential interactions with conventional treatment modalities. For this reason, it is extremely important to inform parents and caregivers of pediatric oncology patients about the use of CAM and dietary supplements to predict and mitigate the occurrence and intensity of the side effects. In the majority of our cases, the patient's guardians informed the healthcare professionals about the CAM and supplement implementation in their children, therefore, they were offered additional information about the possible negative impact of CAM and supplement use on standard medical care in a timely manner.

Abstract
INTRODUCTION Sarcopenia is associated with a higher risk of adverse outcomes among hospitalized patients with chronic diseases. Currently, an unmet need lies in its low diagnostic yield. We conducted a pilot study with the aim to screen hospitalized patients for sarcopenia using the EWGSOP2 criteria. PATIENTS AND METHODS A cross-sectional study among hospitalized patients in internal medicine was carried out, inclusion criteria: age>55, ability to stand-up from a chair. EXCLUSION CRITERIA bed-bound, terminal stages of the disease, ICU stay. We measured hand-grip strength, fat-free mass by bioimpedance and short physical performance battery test (SPPB). Sarcopenia was diagnosed in low hand-grip strength and low muscle mass (EWGSOP2), severe sarcopenia in sarcopenic patients with low physical performance (SPPBT≤8). RESULTS 40 patients were enrolled, sarcopenia was diagnosed in 8/20 (40%) men and 3/20 (15%) women (p=0.15), severe sarcopenia in 6/20 men (30%) and 2/20 (10%) women (p=0.24). 65% of men and 40% of women had SPPBT≤8, and 60% of men and 55% of women had gait speed≤0.8m/s. CONCLUSION Among hospitalized internal medicine patients sarcopenia and severe sarcopenia are common, particularly in males. New diagnostic criteria provide a relatively simple and applicable tool for screening among internal medicine inpatients (Tab. 3, Ref. 25).

Abstract
We report a case of a one-year-old boy who was referred to our clinic suspected of having acute abdomen. On physical examination, the abdomen was soft, diffusely tender with weak peristalsis. Ultrasonography and MRI of the right hemiabdomen demonstrated a well-defined, solid, expansive formation with slightly lobulated contours and an interspersed inhomogeneous structure with overall dimensions of 59 × 45 × 50 mm. After midline laparotomy was performed, a cystic tumor was found, twisted around a pedicle which was arising from the falciform ligament and it measured 5-6 cm in diameter. The tumor appeared to be necrotic. The mass was ligated and extirpated on the pedicle and sent for histopathological analysis. After the surgery, the boy was hemodynamically stable, without respiratory complications and all laboratory findings were within normal limits. Histopathological analysis showed that the tumor was composed of mesenchymal stroma with sparse glimpses of hepatocytes and bile ducts with partly cystic changes lined by orderly epithelium. Given the clinical data, histology and immunohistochemistry analysis (alpha-fetoprotein, CK8/18, hepatocyte, desmin and CD31) a diagnosis of a twisted mesenchymal hamartoma of the liver was made.

Abstract
UNLABELLED This paper provides a framework for the development of national guidelines for the management of glucocorticoid-induced osteoporosis in men and women aged 18 years and over in whom oral glucocorticoid therapy is considered for 3 months or longer. INTRODUCTION The need for updated guidelines for Europe and other parts of the world was recognised by the International Osteoporosis Foundation and the European Calcified Tissue Society, which set up a joint Guideline Working Group at the end of 2010. METHODS AND RESULTS The epidemiology of GIO is reviewed. Assessment of risk used a fracture probability-based approach, and intervention thresholds were based on 10-year probabilities using FRAX. The efficacy of intervention was assessed by a systematic review. CONCLUSIONS Guidance for glucocorticoid-induced osteoporosis is updated in the light of new treatments and methods of assessment. National guidelines derived from this resource need to be tailored within the national healthcare framework of each country.

Abstract
Although the role of angiogenesis in tumor progression and response to treatment is generally well-characterized, for neuroblastomas clinical data regarding the contribution of angiogenesis and its predictive capacity remain unclear. The aim of this study was to evaluate whether tumor vascularity in the combination with expression of vascular endothelial growth factor (VEGF) represent prognostic factors for patients with neuroblastoma. Immunohistochemistry using anti-CD34 and anti-VEGF antibodies was used to analyze paraffin-embedded primary tumor tissues from 56 patients diagnosed with neuroblastoma. Tumor vascularity was estimated by calculating the tumor vascular volume fraction (TVVF), and VEGF expression was determined using semi-quantitative scoring. Statistical analyses including multivariate analysis were performed and compared with these two factors. Tumor vascularity had impact on survival of high VEGF expression neuroblastoma patients. Combination of high VEGF expression and TVVF value < or = 5% was independent predictor of overall survival (p-value = 0.0041, odds ratio (OR) (95% CI) = 8.67 (1.99-37.69) by the Cox proportional hazards model). This study revealed for the first time a group of extremely high-risk neuroblastoma with both high VEGF expression and poor vascularity. For these patients reduced rates of survival were observed (37% vs. 92.5%) (p < 0.0001). These patients did not experience a significant improvement following hematopoietic stem cell transplantation, and could be candidates for receiving novel therapies. These results indicate the importance of the mutual relationship between tumor vascularity and VEGF, because it gives better insight into the prognosis of patients with neuroblastoma.

Abstract
The aim of this retrospective study was to assess a ten-year experience in the treatment of rare complications of ventriculoperitoneal shunting--intraabdominal cerebrospinal fluid pseudocysts. At this time there are no data about incidence, clinical course and treatment of these complications in Croatia. Cerebrospinal fluid (CSF) abdominal pseudocyst is an uncommon but important complication of ventriculoperitoneal shunts. Retrospective data were obtained from 5 children with abdominal CSF pseudocysts, treated between 1996 and 2007. The incidence of intraabdominal CSF pseudocysts in our study is 2.9%. All patients were girls ranged in age from 4 to 12 years old (mean 8.8 years). In most cases etiology of hydrocephalus was congenital, idiopathic. Abdominal pain and distension were the most frequent clinical finding (4/5). Although infection has been reported as responsible for pseudocyst formation, we did not found it in our series. Laparotomy with cyst wall excision and catheter replacement was performed in 2/5 cases, and only cyst fluid aspiration with catheter replacement in 3/5 cases. Recurrence of the abdominal cyst was observed in one girl who was in terminal stadium of anaplastic ependymoma. It is our opinion that only catheter replacement and cyst fluid evacuation, as one of the treatment modalities, may be successful, even in large CSF intraperitoneal pseudocysts.

Abstract
OBJECTIVE Psychological interactions between parents,children and social environment are very important for childhood health. The type of personality and stressful events are probably also cancer risk factors. We investigated personality types A/B and D (negative affectivity and social inhibition) in parents of children with cancer (PCC), as well as social environmental factors, and family / children's stressful events before the appearance of cancer. SUBJECTS AND METHODS Bortner Type A Scale for evaluating parental type A/B personality, and 14 question personality test (DS14) for parental type D personality (negative affectivity and social inhibition score) were performed. Questionnaire eligible information about stressful events and social environmental factors in children with cancer (CC) were analyzed. RESULTS Analyzing 127 PCC and 136 parents of healthy children (PHC) we found no significant differences in A/B type personality and social inhibition. There was significant difference in negative affectivity. PCC had more negative affectivity than PHC. We found more stressful events before cancer appearance in the families of children with cancer (FCC) than in healthy families (FHC), and more children's stressful events in CC then in healthy ones (HC). There were more quarrels in FCC, while CC were more "easy good-mannered children" than HC. CONCLUSIONS Our results support the hypothesis that stress is a cancer risk factor and the idea that impaired parental functioning may be a mechanism linking family stress with the aetiology of cancer.

Abstract
Familial hemophagocytic lymphohistiocytosis (FLH) is an autosomal recessively inherited multisystem disease. This defect in cellular cytotoxicity is a life threatening condition characterized by fever, rash, splenomegaly, cytopenias and neurologic manifestations. PRF1, UNC13D and STX11 gene defects underlie in about 40-50% of primary cases. Chemoimmunotherapy followed by hematopoietic stem cell transplantation improved disease outcome. We report a case of a 6-week-old boy who presented with a fever, diffuse rash, disseminated intravascular coagulation, hypofibrinogenemia, hypertrigliceridemia, hepatosplenomegaly, leukocytosis with 90% of lymphocytes, granulocytopenia, anemia, trombocytopenia, hyperferritinemia and pathological findings in cerebrospinal fluid. The patient had decreased frequency of NK cells and low NK cell activity in peripheral blood. Bone marrow aspiration analysis showed degenerative changes of histocyte cells, with preserved cytophages (lymphophages and erythrophages) consistent with hematophagocytic syndrome. Given that the molecular diagnosis of the known mutations in genes PRF1 and UNC13D showed a mutation in UNC13D, the diagnosis of familial hemophagocytic lymphohistiocytosis subtype 3 was established. HLH-2004 chemotherapy protocol was performed and partial remission with residual central nervous system disease was achieved. Hematopoietic stem cell transplantation was successfully performed with an unrelated HLA-matched donor. Familiar HLH is generally a progressive and fatal disease. Early diagnosis with molecular genetic analysis and chemoimmunotherapy followed by hematopoietic stem-cell transplantation is the best approach.

Abstract
PURPOSE Ki-67, tumor proliferation marker, is an important prognostic factor in a variety of cancers. In the present study, we investigated the expression and the prognostic value of Ki-67 in nephroblastoma. METHODS Ki-67 expressions were investigated by immunohistochemistry on paraffin-embedded material in 48 children operated on because of nephroblastoma. Patients were treated according to SIOP protocol. The mean follow-up period was 5.4 years. A proliferation index was obtained by immunohistochemistry using anti-Ki-67 anti-body. RESULTS The mean Ki-67 proliferation index in the blastemal type was 12.3%, and in the epithelial type, 21.4%. In the anaplastic type, Ki-67 proliferation index was: in the blastemal component 20%, in the stromal 21%, and in the epithelial 31%. In the mixed tumor type, Ki-67 proliferation index was assessed as: in the blastemal component 10%, in the epithelial 33% and in the stromal 31.5%. Proliferation index for the epithelium was significantly higher than those found for the blastema (P = 0.001). A correlation between Ki-67 and tumor stage found proliferation index significantly higher in stages I and II (P = 0.002). CONCLUSION The results support the conclusion that Ki-67 is a relevant marker for assessing the proliferative activity and tumor cell dynamics of nephroblastoma, but it may not be a good clinical prognostic marker.

Abstract
INTRODUCTION Wrist fracture causes pain and decreased physical, social and emotional function. The International Osteoporosis Foundation has developed a specific questionnaire to assess quality of life in patients with wrist fracture. This questionnaire, including 12 questions, was validated in a multicentre study and compared with an osteoporosis-specific questionnaire (Qualeffo-41) and a generic questionnaire (EQ-5D). METHODS The study included 105 patients with a recent wrist fracture and 74 sex- and age-matched control subjects. The questionnaire was administered as soon as possible after the fracture, at 6 weeks, 3 months, 6 months and 1 year after the fracture. Test-retest reproducibility, internal consistency and sensitivity to change were assessed. RESULTS AND DISCUSSION The results showed adequate repeatability and internal consistency of the International Osteoporosis Foundation (IOF) wrist fracture questionnaire. The discriminatory capacity between patients and control subjects was very high, with significant odds ratios for each question and domain. The IOF-wrist fracture questionnaire domain scores showed significant improvement after 3 and 6 months and some improvement from 6 months up to 1 year. The sensitivity to change was much higher for the IOF-wrist fracture total score than for Qualeffo-41 and EQ-5D. CONCLUSION In conclusion, the IOF-wrist fracture questionnaire appears to be a reliable and responsive quality of life questionnaire.

Abstract
Background Despite aggressive therapy, advanced stage neuroblastoma patients have poor survival rates. Although angiogenesis correlates with advanced tumour stage and plays an important role in determining the tumour response to treatment in general, clinical data are still insufficient, and more clinical evaluations are needed to draw conclusions. The aim of this study was to evaluate vascular endothelial growth factor (VEGF) expression in patients with neuroblastoma, determine whether it correlates with other prognostic factors and/or therapeutic response, and to assess should VEGF be considered in a routine diagnostic workup. Materials and methods VEGF expression was determined by immunohistochemistry using anti-VEGF antibody in paraffin embedded primary tumour tissue from 56 neuroblastoma patients. Semiquantitative expression of VEGF was estimated and compared with gender, age, histology, disease stage, therapy, and survival. Statistical analyses, including multivariate analysis, were performed. Results VEGF expression correlated with disease stage and survival in neuroblastoma patients. Combination of VEGF expression and disease stage as a single prognostic value for survival (P-value = 0.0034; odds ratio (OR) (95%CI) = 26.17 (2.97-230.27) exhibited greater correlation with survival than individually. Hematopoietic stem cell transplantation significantly improved survival of the advanced stage patients with high VEGF expression. Conclusion VEGF expression should be considered in a routine diagnostic workup of children with neuroblastoma, especially in those more than 18 months old and with advanced disease stage. High VEGF expression at the time of disease diagnosis is a bad risk prognostic factor, and can be used to characterize subsets of patients with an unfavourable outcome.

Abstract
Central venous catheters provide an easy access for intravenous medications. Having a central line in place will relieve a child from the discomfort and danger of multiple regular intravenous lines for chemotherapy. The use of indwelling central venous catheters has become commonplace in the management of children undergoing oncological treatment. There are two types of central lines commonly used. There are Broviac catheters and Port-A-Cath (PAC) catheters. In the last 5 years we inserted 194 catheters in 175 children. We inserted 121 Broviac catheters and 73 PAC catheters. During the follow up of 39382 catheter days 44 complications were observed. In Broviac group the median follow up was 155 days and in PAC group was 230 days. We observed differences in the incidence between two devices. In Broviac group infections were more frequent and in PAC group other complications were more frequent than infections.

Abstract
The mast-cell sarcoma of a bone is described here for the first time. The tumour presented in a 4-year-old boy, with pain, oedema and deformation of his right lower leg. Radiological findings revealed a destructive tumourous mass. Histopathological examination showed the tumour to be composed of large, atypical cells, with hyperchromatic oval and polygonal nuclei. The cytoplasm around them was eosinophilic with many basophilic and toluidine-blue-positive granules. These atypical mast cells were positive for chloroacetate esterase, c-kit, tryptase and negative for myeloperoxidase. The primary disease quickly progressed to mast-cell leukaemia, and despite intensive chemotherapy the patient died 18 months after first symptoms.

Abstract
BACKGROUND Ovarian dysgerminoma cases are very rarely presented together with acute abdomen. The purpose of this study is to present dysgerminoma ovarii with abdominal pain in lower right abdominal part after abdominal trauma as an abdominal emergency. PATIENTS AND METHODS Our 12-year old female patient was admitted to our hospital after traffic accident with abdominal trauma. On physical examination the abdomen was acute and the mass in lower abdomen was palpated. Ultrasound and CT examinations showed the presence of large, multilobulated and predominantly solid pelvic mass. Fluid was found in the lower part of pelvis. Immediate exploratory laparotomy was performed. It exposed a superficial actively bleeding tumour vessel. We stopped the bleeding and did a biopsy of the tumour because it was too big for surgical treatment. CONCLUSION Ovarian dysgerminoma should be part of the differential diagnosis in female children with acute surgical abdomen when a solid mass is detected by ultrasonographic scan (Fig. 4, Ref. 11).

Abstract
BACKGROUND Vertebral fractures are associated with back pain and disability; however, relatively little is known about the impact of radiographic vertebral fractures on quality of life in population samples. The aim of this study was to determine the impact of a recent radiographic vertebral fracture on health-related quality of life (HRQoL). METHODS Men and women aged 50 years and over were recruited from population registers in 12 European centers. Subjects completed an interviewer-administered questionnaire and had lateral spine radiographs performed. Subjects in these centers were followed prospectively and had repeat spinal radiographs performed a mean of 3.8 years later. Prevalent deformities were defined using established morphometric criteria, and incident vertebral fractures by both morphometric criteria and qualitative assessment. For each incident fracture case, three controls matched for age, gender, and center were selected: one with a prevalent deformity (at baseline) and two without prevalent deformities. All subjects were interviewed or completed a postal questionnaire instrument which included Short Form 12 (SF-12), the EQ-5D (former EuroQol), and the quality of life questionnaire of the International Osteoporosis Foundation (QUALEFFO). The median time from the second spinal radiograph until the quality of life survey was 1.9 years. Comparison between cases and their matched controls was undertaken using the signed rank test. RESULTS 73 subjects with incident vertebral fracture (cases), mean age 64.8 years (of whom 23 had a baseline deformity), and 196 controls, mean age 63.9 years (of whom 60 had a baseline deformity), were studied. There were strong correlations between the domain scores for each of the three instruments. There was no statistically significant difference in any of the domain scores between cases and those controls with a prevalent deformity. However, compared with the controls without a prevalent deformity the cases had significantly impaired quality of life as determined using the total QUALEFFO score (38.2 vs 33.7), the physical component score of the SF-12 (39.9 vs 43.7) and the health status score of the EQ-5D (62.3 vs 69.9). When the analysis was repeated after stratification of the cases by baseline deformity status (i.e., cases with and without a prevalent deformity at baseline), cases with a prevalent deformity had impaired quality of life compared with their matched controls, both with and without a prevalent deformity. In contrast there was no significant difference in quality of life among the cases without a prevalent deformity and either control group. CONCLUSIONS In this population-based study a recent vertebral fracture was associated with impairment in quality of life, though this was mainly among those who had sustained a previous vertebral deformity.

Abstract
There is important geographic variation in the occurrence of the major osteoporotic fractures across Europe. The aim of this study was to determine whether between-center variation in limb fracture rates across Europe could be explained by variation in the incidence of falls. Men and women, aged 50-79 years, were recruited from population-based registers in 30 European centers. Subjects were followed by postal questionnaire to ascertain the occurrence of incident fractures, and were also asked about the occurrence and number of recent falls. Self-reported fractures were confirmed, where possible, by review of the radiographs, medical record, or subject interview. The age- and gender-adjusted incidence of falls was calculated by center using Poisson regression. Poisson regression was also used to assess the extent to which between-center differences in the incidence of limb fractures could be explained by differences in the age- and gender-adjusted incidence of falls at those centers. In all, 6302 men (mean age 63.9 years) and 6761 women (mean age 63.1 years) completed at least one questionnaire concerning fractures and falls. During a median follow-up time of 3 years, 3647 falls were reported by men and 4783 by women. After adjusting for age and gender, there was evidence of significant between-center differences in the occurrence of falls. There was also between-center variation in the occurrence of upper limb, lower limb, and distal forearm fractures. Variation in the age- and gender-adjusted center-specific fall rates explained 24%, 14%, and 6% of the between-center variation in incidence of distal forearm and upper and lower limb fractures, respectively. Given the constraints inherent in such an analysis, in men and women aged 50-79 years, variation in fall rates could explain a significant proportion of the between-center variation in the incidence of limb fracture across Europe.

Abstract
The aim of this population-based prospective study was to determine the incidence of limb fracture by site and gender in different regions of Europe. Men and women aged 50-79 years were recruited from population registers in 31 European centers. Subjects were invited to attend for an interviewer-administered questionnaire and lateral spinal radiographs. Subjects were subsequently followed up using an annual postal questionnaire which included questions concerning the occurrence of new fractures. Self-reported fractures were confirmed where possible by radiograph, attending physician or subject interview. There were 6451 men and 6936 women followed for a median of 3.0 years. During this time there were 140 incident limb fractures in men and 391 in women. The age-adjusted incidence of any limb fracture was 7.3/1000 person-years [pyrs] in men and 19 per 1000 pyrs in women, equivalent to a 2.5 times excess in women. Among women, the incidence of hip, humerus and distal forearm fracture, though not 'other' limb fracture, increased with age, while in men only the incidence of hip and humerus fracture increased with age. Among women, there was evidence of significant variation in the occurrence of hip, distal forearm and humerus fractures across Europe, with incidence rates higher in Scandinavia than in other European regions, though for distal forearm fracture the incidence in east Europe was similar to that observed in Scandinavia. Among men, there was no evidence of significant geographic variation in the occurrence of these fractures. This is the first large population-based study to characterize the incidence of limb fracture in men and women over 50 years of age across Europe. There are substantial differences in the descriptive epidemiology of limb fracture by region and gender.

Abstract
The presence of a vertebral deformity increases the risk of subsequent spinal deformities. The aim of this analysis was to determine whether the presence of vertebral deformity predicts incident hip and other limb fractures. Six thousand three hundred and forty-four men and 6788 women aged 50 years and over were recruited from population registers in 31 European centers and followed prospectively for a median of 3 years. All subjects had radiographs performed at baseline and the presence of vertebral deformity was assessed using established morphometric methods. Incident limb fractures which occurred during the follow- up period were ascertained by annual postal questionnaire and confirmed by radiographs, review of medical records and personal interview. During a total of 40348 person-years of follow-up, 138 men and 391 women sustained a limb fracture. Amongst the women, after adjustment for age, prevalent vertebral deformity was a strong predictor of incident hip fracture, (rate ratio (RR) = 4.5; 95% CI 2.1-9.4) and a weak predictor of 'other' limb fractures (RR = 1.6; 95% CI 1.1-2.4), though not distal forearm fracture (RR = 1.0; 95% CI 0.6-1.6). The predictive risk increased with increasing number of prevalent deformities, particularly for subsequent hip fracture: for two or more deformities, RR = 7.2 (95% CI 3.0-17.3). Amongst men, vertebral deformity was not associated with an increased risk of incident limb fracture though there was a nonsignificant trend toward an increased risk of hip fracture with increasing number of deformities. In summary, prevalent radiographic vertebral deformities in women are a strong predictor of hip fracture, and to a lesser extent humerus and 'other' limb fractures; however, they do not predict distal forearm fractures.

Abstract
Hip geometry and bone mineral density (BMD) have been shown previously to relate, independently of each other, to risk of hip fracture. We used Lunar DPX "beta" versions of hip strength analysis (HSA) and hip axis length (HAL) software to analyze scans from ten representative age-stratified population samples in the European Prospective Osteoporosis Study (EPOS). All 1617 subjects were >50 years of age, and 1033 were women. The data were modeled with gender and center as categorical variables. The bone mineral density of the upper half of the femoral neck declined at a faster rate with age than that in the lower half. Femoral neck cross-sectional moment of inertia (CSMI), a measure of resistance to bending, showed no significant age reduction in either gender. However, height and weight effects on CSMI were significantly more beneficial in men than in women (0.002 < p < 0.012) and the weight effect appeared to be mediated by bone mineral content (BMC). Compressive stress (Cstress), defined as the stress in the femoral neck at its weakest cross section arising from a standardized fall, was higher in women. Although Cstress increased with body weight when BMC was held constant, in practice it fell through the association and statistical interaction of rising body weight with rising BMC. HAL, as expected, was strongly positively associated with male gender and also height (p < 0.0001). Hip strength-related indices were markedly center-dependent. Significant differences (p < 0.0001) were noted between the centers for all the variables investigated that related to hip geometry. Adjustment for femoral neck bone mineral content (totBMC) showed these center differences to account for >50% of center variation in hip strength, which remained highly significant (p < 0.0001). We conclude that there are substantial geographical differences in femoral neck geometry as well as in BMD. These geometric variations may contribute to the large variations in hip fracture risk across Europe. The effects of aging on hip strength need to be explored in longitudinal studies.

Abstract
A tartrate-resistant acid phosphatase (TrACP), which has been suggested to be very similar to the osteoclastic TrACP, was partially purified from the spleen of a patient with hairy cell leukemia. The purification procedure consisted of carboxymethyl-Sepharose, phosphocellulose, Sephacryl S-200, and phenyl-Sepharose chromatographies. Polyclonal antibodies were generated in guinea pigs with a titer of at least 1:6000. Immunohistochemical staining of fetal rat tibia with the antisera revealed that only the lysosomes of osteoclasts, but not osteoblasts, were stained. An enzyme-linked immunosorbent assay (ELISA) was developed with the antisera. There was no cross-reactivity with 1) partially purified acid phosphatases (ACPs) from normal human and beef spleens, 2) ACPs in extracts of human osteoblastic cells, 3) purified bovine bone matrix TrACP, or 4) commercial prostatic ACP. However, extracts of giant cell bone tumors, containing large amounts of bona fide osteoclasts, showed large amounts of cross-reactive material, which diluted in parallel with the partially purified hairy cell leukemic TrACP in the ELISA. Commercial serum band 5b TrACP also displaced in parallel with the partially purified hairy cell leukemic TrACP. Immunoblotting studies revealed that the antiserum, but not nonimmune guinea pig serum, reacted with the homogeneous hairy cell leukemia splenic band 5 TrACPs, which were recently purified by our laboratory. Preliminary application of the ELISA to sera of patients with metabolic bone diseases revealed that normal healthy individuals had measurable amounts of the immunoreactive material, and patients with Paget's disease or hyperparathyroidism, who should have high bone turnover, had elevated levels of this immunoreactive material in their sera. In contrast, the level of serum osteoclastic TrACP in a patient with an acute lymphatic leukemia was normal. In summary, 1) we have shown that hairy cell leukemia splenic TrACP shares significant immunological similarity with the osteoclastic TrACP and with the serum band 5b TrACP, and 2) the ELISA holds promise for a sensitive and specific assay for bone resorption.
