Abstract
BACKGROUND GPVI is a major platelet collagen signaling receptor. In rare cases of immune thrombocytopenic purpura (ITP), autoantibodies to GPVI result in receptor shedding. OBJECTIVES To investigate a possible pathogenic role of plasma anti-GPVI antibody located in a woman with lupus nephritis. METHODS Measured were (i) platelet aggregation to collagen and convulxin, (ii) platelet GPVI expression (flow cytometry and western blotting), (iii) plasma soluble GPVI (sGPVI, dual antibody ELISA), and (iv) plasma anti-GPVI antibody (ELISA using recombinant sGPVI). RESULTS In 2006 and early 2007, the patient had a normal platelet count but a virtual absence of platelet aggregation to collagen and convulxin. Her platelets responded normally to other agonists including cross-linking ITAM-dependent FcgammaRIIA by monoclonal antibody, IV.3. Flow cytometry and western blotting showed a platelet deficiency of GPVI. Plasma sGPVI levels were undetectable whereas ELISA confirmed the presence of anti-GPVI antibody. Sequencing revealed a normal GPVI cDNA structure. The patient's plasma and the isolated IgG3 fraction activated and induced GPVI shedding from normal platelets. A deteriorating clinical condition led to increasingly strict immunosuppressive therapy. This was globally associated with a fall in plasma anti-GPVI titres, the restoration of platelet GPVI and the convulxin response, and the loss of her nephrotic syndrome. CONCLUSIONS Our results show that this patient acquired a potent anti-GPVI IgG3 antibody with loss of GPVI and collagen-related platelet function. Further studies are required to determine whether anti-GPVI antibodies occur in other lupus patients with nephritis.

Abstract
Primary adrenal non-Hodgkin's lymphoma is very rare. We have seen 2 such cases among 241 cases of non-Hodgkin's lymphoma (0.83%) over the past 4 years. We could detect 2 more cases who had adrenal involvement, in addition to other extra nodal disease sites. Review of English literature revealed 65 cases of primary adrenal non-Hodgkin's lymphoma, most being single case reports. Salient features included-median age of 68 years (mean age of 47.25 years in our series), bilateral adrenal involvement in 60%, and predominantly diffuse large cell histology with 'B' cell immunophenotype. Adrenal insufficiency was present in two-thirds of the patients at diagnosis. Chemotherapy with or without radiotherapy is the mainstay of treatment. About half the patients respond to treatment, with median survival of 4 months. The high index of suspicion for early diagnosis and prompt treatment may improve outcome.

Abstract
Electrical stimulation has been shown to improve functional assembly of cardiomyocytes in vitro for cardiac tissue engineering. Carbon electrodes were found in past studies to have the best current injection characteristics. The goal of this study was to develop rational experimental design principles for the electrodes and stimulation regime, in particular electrode configuration, electrode ageing, and stimulation amplitude. Carbon rod electrodes were compared via electrochemical impedance spectroscopy (EIS) and we identified a safety range of 0 to 8 V/cm by comparing excitation thresholds and maximum capture rates for neonatal rat cardiomyocytes cultured with electrical stimulation. We conclude with recommendations for studies involving carbon electrodes for cardiac tissue engineering.

Abstract
Overcoming the limitations of diffusional transport in conventional culture systems remains an open issue for successfully generating thick, compact and functional cardiac tissues. Previously, it was shown that perfusion systems enhance the yield and uniformity of cell seeding and cell survival in thick cardiac constructs. The aim of our study was to form highly functional cardiac constructs starting from spatially uniform, high density cell seeded constructs. Disk-shaped elastomeric poly(glycerol sebacate) scaffolds were seeded with neonatal rat cardiomyocytes and cultured for eight days with direct perfusion of culture medium or statically in a six-well plate. In the perfusion experimental group, the integrity of some disks was well maintained, whereas in others a central hole was formed, resulting in ring-shaped constructs. This allowed us to also study the effects of construct geometry and of interstitial flow versus channel perfusion. The ring-shaped constructs appeared to have a denser and more uniform deposition of extracellular matrix. In response to electrical stimulation, the fractional area change of the ring-shaped constructs was 7.3 and 2.7 times higher than for disk-shaped tissues cultured in perfusion or statically, respectively. These findings suggest that a combination of many factors, including scaffold elasticity and geometry and the type of perfusion system applied, need to be considered in order to engineer a cardiac construct with high contractile activity.

Abstract
BACKGROUND Vitamin D nutrition has a profound effect on the development of an infant. Vitamin D status of mothers and their infants are closely correlated. While hypovitaminosis D has emerged as a significant public health problem across all age groups, there is limited information of this condition in lactating mothers and their breast fed infants. AIM To evaluate the vitamin D status of lactating mothers and their breast fed infants. SUBJECTS AND METHODS 180 healthy lactating mothers and exclusively breast fed infants, 2-24 weeks old, were recruited for the study. The mother-infant pairs underwent concurrent clinical, biochemical and hormonal evaluation for calcium-vitamin D-PTH axis. RESULTS The mean serum 25(OH)D values in lactating mothers was 27.2 +/- 14.6 nmol/l (10.9 +/- 5.8 ng/ml), while that of their infants was 28.9 +/- 20.8 nmol/l (11.6 +/- 8.3 ng/ml). Serum 25(OH)D levels <25 nmol/l (10 ng/ml) were found in 47.8% of the mothers and 43.2% of the infants. Among these, elevated PTH levels (>54 pg/ml) were seen in 59.3% of the mothers and 69.6% of the infants. A highly significant negative correlation was found between serum 25(OH)D and PTH in mothers (r = -0.480, p = 0.01) and their infants (r = -0.431, p = 0.01). A strong positive correlation was seen of 25(OH)D levels in mother-infant pairs (r = 0.324, p = 0.001). CONCLUSIONS A high prevalence of vitamin D deficiency was found in lactating mothers and their exclusively breast fed infants. Infants born to mothers with hypovitaminosis D had 3.8 times higher risk of developing hypovitaminosis D as compared to those born to mothers with normal vitamin D levels.

Abstract
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.

Abstract
OBJECTIVES To evaluate the role of thyroid ultrasound in children with autoimmune thyroiditis diagnosed either on cytopathology or by the presence of thyroid peroxidase antibodies. DESIGN AND SETTINGS Children presenting for the first time to the Thyroid Clinic at the Institute of Nuclear Medicine and Allied Sciences for the complaint of goiter over a two year period (January 2005-December 2006) were studied. SUBJECTS 695 school children (244 boys and 451 girls) aged 5-18 year were studied. METHODS Children were subjected to thyroid ultrasound, cytopathology, thyroid peroxidase antibody and thyroid function tests. RESULTS Overall, 16% of goitrous children had hypoechogenicity on ultrasound, 15.2% had cytopathological evidence of thyroiditis, 10.6% had positive thyroid peroxidase antibodies and 25.2% had abnormal thyroid function tests. Subjects with hypoechogenicity had higher percentage of thyroiditis on cytopathology (41.4% vs. 10.3%; P<0.01), thyroid peroxidase antibody positivity (30.6% vs. 6.8%; P<0.01) and thyroid dysfunction (46.8% vs. 21.2%; P<0.01) than those with normal echogenicity. CONCLUSION Thyroid USG has a useful, though limited, role in excluding thyroid disease in children. The sensitivity of echogenicity for the diagnosis of autoimmune thyroiditis in children is less than that reported in adults.

Abstract
BACKGROUND Ultrasound assessment of thyroid volume is considered a more objective method than clinical palpation for the diagnosis of goitre. We used ultrasonography to establish normal reference cut-off points of thyroid volume in schoolchildren of different socioecomonic groups in India and compared the results with international norms. METHODS In a cross-sectional study, we clinically examined 27,250 children from the lower and higher socioeconomic strata (SES) from all over India to determine their goitre staging. A single sonologist, using ultrasonography, assessed the thyroid volume in a subset of 15,986 children (8463 from the lower and 7523 from the higher SES). Students were recruited from at least one school each representing the higher and the lower SES, from cities located in 5 zones of India. Children with known thyroid disorders were excluded from the study. RESULTS Clinical evaluation revealed a mean goitre prevalence of 19.9% (23.2% in girls; 16.5% in boys; 17.1% in the higher SES; 23.5% in the lower SES). The thyroid volume as assessed by ultrasonography was significantly higher in children from the lower SES (mean 5.65 ml, SE 0.02) compared with those from the higher SES (mean 5.02 ml, SE 0.02) after adjusting for the imbalance in body surface area (p < 0.001). Using international norms (WHO 2004), the prevalence of goitre in various body surface area categories among children who had no goitre on clinical examination ranged from 48.2% to 75.1% for boys and 23.2% to 67.4% for girls. CONCLUSION The striking discrepancy in the prevalence of goitre assessed by using clinical examination and ultrasound techniques suggests that the norms recommended by WHO based on ultrasound techniques are not appropriate for India.

Abstract
INTRODUCTION Steroid-induced osteoporosis is a major problem after organ transplantation. There is considerable evidence that bisphosphonates are effective in decreasing osteoporosis. AIM This prospective study was carried out to see the effects of bisphosphonates on bone mineral density (BMD) after successful renal transplantation. MATERIAL AND METHODS Fifty consecutive patients of successful renal transplantation were randomized into two groups. Group A (n = 27) received 35 mg/wk of Alendronate for 6 months after transplantation. Group B (n = 23) did not receive Alendronate and served as a control. Both groups underwent a pretransplant baseline dual-energy X-ray absorptiometry (DEXA) scan of their hips and lumber spines. Both groups received oral calcium and vitamin D supplement. Both groups were matched for the regimen and dose of immunosuppressive drugs. BMD was measured at 3 months and 6 months after transplantation. RESULTS Both groups showed a decline in BMD in early months posttransplantation. However, the 6-month DEXA scans showed a significant rise in BMD in group A as compared to group B. CONCLUSION Bisphosphonates appear to have a beneficial effect on steroid-induced bone loss.

Abstract
UNLABELLED Peripheral bone density measurements are scarce and the factors, which predict bone mineral density at these sites, especially in children, are not clearly known. In this study, age, height, weight and alkaline phosphatase had a significant association on peripheral bone mineral density in healthy Indian school girls. INTRODUCTION Factors that lead to the attainment of peak bone mass at peripheral sites, during period of growth are not clearly known. METHODS Six-hundred and sixty-four randomly selected 7- to 17-year-old girls from upper and lower socioeconomic status (USES/LSES) schools were assessed clinically and a recording of their height and weight was undertaken. Serum calcium, phosphorus, total alkaline phosphatase (ALP), 25-hydroxyvitamin D (25-OHD) and parathyroid hormone (PTH) were measured in all of them. Bone mineral density (BMD) was measured at the distal forearm (BMDdf) and calcaneum (BMDca) by peripheral dual energy X-ray absorptiometry (pDXA). RESULTS Girls belonging to the USES were significantly taller (149.7 +/- 12.3 cm vs 144.4 +/- 11.9 cm; P < 0.001) and weighed more (44.3 +/- 12.9 kg vs 35.9 +/- 10.0 kg; P < 0.001) than girls from the LSES. USES girls had a significantly higher mean serum calcium (9.3 +/- 0.7 mg/dl vs 9.2 +/- 0.8 mg/dl; P < 0.05) and significantly lower alkaline phosphatase (316 +/- 166 IU/l vs 423 +/- 228 IU/l; P < 0.01) and iPTH (29.9 +/- 18.4 pg/ml vs 45.7 +/- 64.6 pg/ml; P < 0.01). There was no significant difference in mean serum phosphorus and 25-OHD levels between the two groups. USES subjects had higher BMD at both sites than LSES subjects. BMDdf and BMDca increased with age and tended to plateau by 16 years and 12 years of age respectively in both the groups. Age, height and weight explained approximately 50% of the variability, while biochemical parameters explained approximately 30% of variability in BMD at both the sites. The only biochemical parameter which had a significant association with BMD was ALP at the distal forearm. CONCLUSION In conclusion, age, nutrition, height and weight are significantly associated with BMD at peripheral sites.

Abstract
OBJECTIVES Autoimmune thyroid diseases (AITD) encompass a number of conditions that have in common cellular and humoral responses targeting the thyroid gland. Interactions between susceptibility genes and environmental triggers are thought to initiate an autoimmune response to thyroid antigens leading to disease manifestation. Commencement of the disease in childhood leads to the presumption that genetics may have an important role in the causation of the disease. DESIGN The present study was aimed at evaluating the human leucocyte antigen (HLA) encoded susceptibility to develop juvenile autoimmune thyroiditis (JAT) in patients from North India. PATIENTS We studied 48 consecutive patients of JAT along with 176 first-degree relatives for their thyroid function (FT4, TSH) and anti-thyroid peroxidase antibody status (AbTPO). MEASUREMENTS HLA studies were carried out using serology for HLA-class I antigens and DNA analysis of HLA-class II alleles. The data were compared with a cohort of 308 ethnically matched healthy individuals. RESULTS We observed overt hypothyroidism in 50% and AbTPO positivity in 70.8% of the index cases. Among the first-degree relatives, goitre was observed in 51.7%, thyroid dysfunction in 28.4% and AbTPO in 29.5% of individuals. Of the 37 relatives who underwent fine-needle aspiration cytology (FNAC), 60% had evidence of chronic lymphocytic thyroiditis (CLT). A strong positive association of HLA-DRB1*1404 was observed with the JAT (35.4%vs. 10.4%, chi2 = 19.8, Pc = 0.0001). We also observed a higher (72%, P = 0.03) paternal transmission of HLA-DRB1*1404 to affected offspring in comparison to unaffected offspring. HLA-DRB1*03 was also increased among JAT patients but did not reach statistical significance. CONCLUSION These studies point towards an important role of immune modifying genes, such as HLA, in influencing susceptibility to juvenile-onset AITD.

Abstract
AIMS In this study we describe the clinical, anthropometric and biochemical characteristics of patients with early onset Type 2 diabetes mellitus (T2DM) (< 30 years of age) and compare them with healthy, non-diabetic individuals. METHODS In this multisite collaborative study, 51 patients with T2DM (40 male, 11 female) and 69 non-diabetic individuals of similar age and gender distribution (controls) as the cases (46 male and 23 female) were investigated. The following parameters were measured; anthropometry [body mass index (BMI), waist circumference, waist-hip ratio (WHR) and skin-fold thickness at four sites], percentage body fat (%BF) and lipid profile. RESULTS The mean (SD) age of diagnosis of T2DM was 21.4 (6.1) years. A significantly higher number of cases had a history of T2DM in first-degree relatives as compared with controls (82.3 vs. 23.2%, P < 0.001). The mean values and the prevalence of abnormal values of measures of generalized obesity (BMI and %BF) and abdominal obesity (waist circumference and WHR) were significantly higher in cases as compared with controls. Hypertriglyceridaemia [OR (95% CI): 4.6 (1.1-20.0)], high WHR [7.9 (2.5-24.4)] and family history of T2DM [7.3 (2.3-23.0)] were independently associated with T2DM. Age and gender adjusted odds ratios of T2DM were 23.3 (5.2-103.6), 37.7 (9.0-158.5) and 86.4 (17.0-438.5), respectively, with the following set of risk factors; hypertriglyceridaemia and high WHR, hypertriglyceridaemia and family history of T2DM, and high WHR and family history of T2DM. Finally, the presence of all three risk factors increased the odds of T2DM to 112.1 (10.8-1164.7). CONCLUSIONS Early identification of the simple clinical, anthropometric and biochemical parameters which are strongly associated with early onset T2DM in young Asian Indians may be useful for primary prevention.

Abstract
AIM The aims of this study were to determine. The prevalence of foot complications such as neuropathy, peripheral vascular disease (PVD), amputations and infections and the associated diabetic complications and practice of foot care among these subjects. METHODS A total of 1319 type 2 diabetic patients, were selected from four different centres across India. The centres were Diabetes Research Centre (DRC), Chennai, Government Rajaji Hospital (GRH), Madurai, Christian Medical College (CMC), Vellore and All India Institute of Medical Science (AIIMS), Delhi. Details were collected regarding foot problems and associated complications. RESULTS The prevalence of neuropathy was 15% (n=193) and PVD was 5% (n=64). Infections were present in 7.6% (n=100) of patients. The infection rate varied from 6-11% in the different centres. Nearly 3% of subjects had undergone a minor or major amputation. DISCUSSION This study found that the prevalence of infection was 6-11% and prevalence of amputation was 3% in type 2 diabetic patients. Neuropathy (15%) was found to be an important risk factor for diabetic foot infections. Effective foot care advice should be propagated to reduce the burden imposed by diabetic foot complication particularly in developing countries like India.

Abstract
Insulin-dependent diabetes mellitus is associated with renal failure, diabetic retinopathy, neuropathy and vasculopathy. We report the first successful simultaneous pancreas-kidney transplant in India in a young diabetic with renal failure. The dual transplant has cured his diabetes and renal failure and has had a beneficial effect on his neuropathy, retinopathy and quality of life. Obstacles to dual transplant in India include a lack of suitable recipients and a cadaver donor programme that is still in its infancy.
