Abstract
Theophylline, (1,3-dimethylxanthine) is widely used as a smooth muscle relaxant, myocardial stimulant and a diuretic agent. The most frequent use of theophylline is in treatment of acute and chronic asthma as a bronchodilator. To determine the effect of Theophylline on serum electrolyte and uric acid, 21 asthmatic children (age range 1.5-7 years) with severe acute asthma and 25 patients with chronic asthma (5-15 years ) who were being treated with slow-release theophylline were enrolled in this study. Fifty age and sex matched normal children took part as control. Blood samples (5m1) were withdrawn before, during and after completion of the course of intravenous theophylline treatment (0.05-0.70 mg/kg/ hr). Sera obtained were used for analysis of K+, Na+, phosphorus, calcium and uric acid by RA-1000 automated analyzer and the following results were obtained: (1) After treatment, total serum calcium in acute asthmatic patients decreased significantly compared with controls (P<0.01); (2) serum phosphate and K+ levels of acute and chronic asthmatic patients after therapy decreased as compared with controls (P<0.01). (3) Post therapy increase in serum level of uric acid in acute and chronic asthmatic patients was statistically significant as compared with control (P<0.001). We conclude that the serum levels of phosphate, potassium, calcium and uric acid should he monitored in patient receiving theophylline especially during prolonged use and critical emergency cases.

Abstract
AIMS To examine the relationship between social deprivation, intensification of insulin therapy (≥ three injections per day) and diabetes control in children and adolescents. METHODS We performed a longitudinal observational study of 283 children and adolescents with Type 1 diabetes from three UK paediatric centres from 2005 to 2007. We used linear mixed modelling to identify the contribution of the Index of Multiple Deprivation 2004, insulin regimen and demographic factors in explaining longitudinal differences in HbA(1c) levels. RESULTS Overall mean HbA(1c) levels were 8.9% [sd 1.4, 74 mmol/mol (8 mmol/mol)]. Prescribing of intensive therapy increased from 49.2 to 70.1% (χ(2) = 32.9, P < 0.001), but there was no corresponding improvement in HbA(1c) levels. Those from more educationally deprived backgrounds were less likely to be started on intensive therapy (P = 0.04). In linear mixed modelling, factors independently associated with poor metabolic control were greater social deprivation (P = 0.01), particularly lower educational levels (P = 0.006), and non-White ethnicity (P = 0.04). Nested terms analysis showed that increased deprivation interacted with non-White ethnicity (P = 0.009) and with intensive insulin therapy (P = 0.03) to result in poorer metabolic control. In a subgroup intensified from conventional regimens during follow-up (n = 75), greater social deprivation was associated with least success of intensive therapy (P = 0.02). CONCLUSIONS Social deprivation was associated with low uptake and poor success of insulin intensification and this appeared to be largely mediated via lower educational levels.

Abstract
Outcome measures to assess therapeutic interventions in cystic fibrosis (CF) patients with mild lung disease are lacking. Our aim was to determine if the lung clearance index (LCI) can detect a treatment response to dornase alfa in paediatric CF patients with normal spirometry. CF patients between 6-18 yrs of age with FEV(1 )≥ 80% pred were eligible. In a crossover design, 17 patients received 4 weeks of dornase alfa and placebo in a randomised sequence separated by a 4-week washout period. The primary end-point was the change in LCI from dornase alfa versus placebo. A mixed model approach incorporating period-dependent baselines was used. The mean ± sd age was 10.32 ± 3.35 yrs. Dornase alfa improved LCI versus placebo (0.90 ± 1.44; p = 0.022). Forced expiratory flow at 25-75% expired volume measured by % pred and z-scores also improved in subjects on dornase alfa (6.1% ± 10.34%; p = 0.03 and 0.28 ± 0.46 z-score; p = 0.03). Dornase alfa significantly improved LCI. Therefore the LCI may be a suitable tool to assess early intervention strategies in this patient population.

Abstract
This prospective observational clinical study was done to find out the clinical and laboratory parameters of pleural tuberculosis patients, to find out a sensitive and specific tool for diagnosis and to see the effectively of a standard anti-TB regime Isoniazide, Rifampicine, Pyrazinamide, Ethambutol, (2HRZE/4HR) for treatment of pleural tuberculosis in an adult medicine unit, department of Medicine, Chittagong Medical College Hospital, Chittagong, Bangladesh. A series of total thirty-three consecutive pleural tuberculosis patients admitted in that unit over a period of 6 months were enrolled. All thirty-three pleural tuberculosis patients were observed for their demographic and clinical parameters and undergone some relevant investigations like complete blood count, Mantoux test, pleural fluid study and pleural histopathological study. Later on, they were put on anti-tuberculosis therapy without steroid and followed their response after one month. All patients of pleural tuberculosis presented in this medicine unit had fever and cough associated with chest pain (87.9%), dysnoea (42.4%), haemoptysis (9.1%), weight loss (84.4%), anorexia (90.9%). Age of presentation was 34.1+/-16.2 years and of them, 60.7% patients were below 30. Mean Erythrocyte Sedimentation Rate (ESR) was 97.04 mm in 1st hour and 57.6% cases had ESR more than 100. 63.6% had Mantoux Test (MT) positive (>10 mm). Only 6.1% had hemorrhagic effusion and others had straw colored fluid. Mean pleural fluid protein is 5.9 gram/L and sugar 65.7 mg/dl. No Acid Fast Bacilli (AFB) was seen on microscopy in pleural fluid. Pleural biopsy revealed 54.5% granulomatous lesion with or without caseation and another 24.2% shows chronic inflammation. Seventy seven percentage (77%) patients were attended follow-up clinic after 1 month and all patients (100%) were improved with this anti-TB therapy. Of the total patient treated with anti TB drug, 53.5% had no pleural effusion, other had minimum effusion. Only 6.06% require subsequent steroid addition and other measures. Pleural biopsy is the investigations of choice for pleural tuberculosis especially in resource poor countries. Pleural tuberculosis can be treated with a standard anti-TB regime successfully without steroid.

Abstract
OBJECTIVE To compare low dose (0.05 units/kg/h) with standard dose (0.1 units/kg/h) intravenous insulin infusion for the treatment of diabetic ketoacidosis (DKA) in children with type 1 diabetes. STUDY DESIGN Data from five paediatric centres were compared in children who received 0.05 (41 episodes) or 0.1 units/kg/h (52 episodes). RESULTS In the low vs. standard dose group, at 6 h following admission, the fall in blood glucose levels [11.3 (95% confidence interval 8.6 to 13.9) vs. 11.8 (8.4 to 15.2) mmol/L, p = 0.86] and rise in pH [0.13 (0.09 to 0.18) vs. 0.11 (0.07 to 0.15), p = 0.78] were similar. These changes were comparable between doses in relation to: severity of initial acidosis, children newly diagnosed with diabetes or aged less than 5 years. After adjustment for other clinical and biochemical covariates, insulin dose was unrelated to the change in pH and blood glucose levels at 6 h following admission. Comparisons of safety data, particularly in relation to abnormal Glasgow Coma Score, were inconclusive. CONCLUSION In this observational study, low dose was as effective as standard dose intravenous insulin infusion in the initial treatment (less than 6 h) of DKA in children with type 1 diabetes. A randomised controlled trial is required to show true equivalence between doses and to evaluate potential safety benefits.

Abstract
OBJECTIVE To determine the effect of coeliac disease and treatment with a gluten-free diet on growth and glycaemic control in asymptomatic children with Type 1 diabetes. METHODS Data were compared in children with coeliac disease diagnosed by annual antibody screening and jejunal biopsy and treated with a gluten-free diet (n = 49) against individuals who were antibody negative (n = 49) matched for age, sex and duration of diabetes. RESULTS No differences in growth were observed. In the years prior to diagnosis of coeliac disease, mean glycated haemoglobin (HbA(1c)) was lower in cases compared with control subjects [8.3 +/- 1.1% vs. 8.7 +/- 0.9%, P = 0.02 (mean +/- sd)]. In cases, HbA(1c) deteriorated 12 months from the start of a gluten-free diet to levels similar to control subjects (8.9 +/- 1.5% vs. 8.8 +/- 1.5%, P-value for analysis of variance = 0.9). In regression analysis, the diagnosis of coeliac disease and start of a gluten-free diet was associated with a rise in HbA(1c) in the first year of treatment [odds ratio 1.56 (95% confidence intervals 1.16-2.10), P = 0.003] after adjusting for insulin dose and regimen and other variables. CONCLUSIONS In children with Type 1 diabetes, lower HbA(1c) prior to diagnosis of silent coeliac disease rises following treatment with a gluten-free diet to levels similar to those without coeliac disease. Although unproven, these observations may relate to abnormalities at the small bowel mucosa before the appearance of circulating coeliac antibodies.

Abstract
Peroxisome proliferators activated receptor-gamma2 (PPARγ2) represents the transcriptional master regulator of adipocyte differentiation and therefore has been suggested as a candidate gene for obesity, insulin resistance, and dyslipidemia. The objective of the study was to investigate for the first time the potential association of the most common variant Pro12Ala (p.P12A) substitution of the PPARγ2 gene with body mass index (BMI), blood pressure, fasting plasma glucose, plasma total cholesterol, LDL and HDL cholesterol, and plasma triglyceride in a sample of 202 (138 females and 64 male) type 2 diabetic Palestinians. Genotyping of the PPARγ2 p.P12A polymorphism was determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis. The A12 allele was associated with lower fasting plasma glucose (P = .03) but had no influence on blood pressure, BMI, or other metabolic parameters. In obese patients, the p.P12A substitution was associated with elevated total plasma cholesterol levels (P = .02) and a tendency toward increased LDL cholesterol level (P = .06). In conclusion, the p.P12A variant of the PPARγ2 may influence cardiovascular risk through effects on lipid metabolism in obese T2D Palestinian patients.

Abstract
OBJECTIVE To ascertain that antibiotics have no role in the management of bronchiolitis. DESIGN Multicentre randomized control trial (RCT). SETTING Five purposively selected teaching hospitals in Bangladesh. PATIENT Children under 24 months old with bronchiolitis. INTERVENTIONS Children were randomized into three groups of therapeutic interventions: parenteral ampicillin (P-Ab), oral erythromycin (O-Ab) and no antibiotic (N-Ab) in adjunct to supportive measures. MAIN OUTCOME MEASURES Clinical improvement was assessed using 18 symptoms/signs which were graded on a two-point recovery scale of 'rapid' and 'gradual', indicating improvement within 'four days' and 'beyond four days', respectively. RESULTS Each intervention group consisted of 98 +/- 1 children having comparable clinico-epidemiological characteristics at the baseline. The trial revealed that most chesty features (features appearing to arise from chest, i.e. cough, breathing difficulty, wheeze, chest indrawing, tachypnoea, tachycardia, rhonchi and crepitation) demonstrated a gradual recovery, beyond 4th admission day and, not differing among the three intervention groups (p > 0.23, p < 0.62, p = 0.54, p < 0.27, p = 0.75, p = 0.76, p = 0.81, p > 0.98, respectively). Most non-chesty features (features appearing to arise away from chest, i.e. feeding/sleeping difficulties, social smile, restlessness, inconsolable crying, nasal flaring, fever and hypoxaemia) demonstrated a rapid recovery, within 4 days, remaining comparable among the three intervention groups (p < 0.07, p = 0.65, p = 0.24, p < 0.61, p = 0.22, p = 0.84, p = 0.29 and p = 0.96, respectively). However, nasal symptoms (runny nose and nasal blockage) also showed no difference among groups (p = 0.36 and p = 0.66, respectively). Thus, the dynamics of clinical outcome obviates that children not receiving antibiotics had similar clinical outcome than those who did. CONCLUSION In hospital settings, managing bronchiolitis with only supportive measures but without antibiotics remains preferable.

Abstract
OBJECTIVES The presence of an ectopic posterior pituitary gland (EPP) in childhood is associated with isolated GH deficiency (IGHD) and multiple pituitary hormone deficiency. GHD in late adolescence has been defined as a peak GH level <5 microg/l. The aim of this study was to identify the likelihood of persistent GHD in late adolescence in patients with an EPP compared with those with a normally sited posterior pituitary (NPP). METHODS In 18 patients with an EPP and 15 patients with an NPP, clinical, biochemical and radiographic data were collected. RESULTS In the EPP vs. the NPP group, the change in peak GH levels at the end of growth was less (+0.4[95% confidence interval (CI) - 0.8 to 2.7] vs. +4.1[95%CI + 0.4 to +10.5] microg/l, P-value for ancova = 0.03, after adjustment for age and sex). Using a peak GH level of <5 microg/l as a cut-off for GHD, 66% of EPP subjects compared with 40% of NPP subjects had GHD (P = 0.3). Hundred per cent of EPP subjects had a peak GH level on retesting <10 microg/l, compared with 40% of NPP subjects (P < 0.001). CONCLUSION It is important to document GH status at the end of growth, even if there is a structural abnormality of the hypothalamic-pituitary axis. The presence of an EPP compared to an NPP increases the likelihood of persistent GHD by 26%. As all EPP patients had a peak GH level of <10 microg/l, the cut-off for persistent GHD in late adolescence may need to be revised.

Abstract
Iron storage disease (haemochromatosis) is thought to be the cause of many disorders unique to captive black rhinoceroses (Diceros bicornis). To establish reliable reference ranges for iron parameters, serum samples from 27 eastern black rhinoceroses (Diceros bicornis michaeli) from a translocation programme in Kenya were analysed and compared with the samples from 17 captive individuals. The transferrin saturation, serum iron concentration and gamma glutamyl transferase were significantly higher in the captive rhinoceroses, but these elevations were not evident when the results were compared with previously published data.

Abstract
AIMS To prospectively determine the change in prevalence of microalbuminuria in relation to changes in glycaemic control in children diagnosed with type 1 diabetes between 1986 and 1996. DESIGN Prospective observational study of an inception cohort. SETTING The geographically defined region of Oxfordshire, UK. PATIENTS 527 children diagnosed with type 1 diabetes under 16 years of age, were divided into three groups based on year of diagnosis of diabetes: group A (1986-1989, n = 165), group B (1990-1993, n = 179) and group C (1994-1996, n = 183). Each group was followed prospectively for 10 years. MAIN OUTCOME MEASURES Cumulative prevalence of microalbuminuria. RESULTS After 4052 patient years of follow-up, in groups C versus B versus A, the cumulative prevalence of microalbuminuria was 31.7% (95% CI 20.9 to 42.5), 24.8% (17.8 to 31.8) and 23.2% (15.4 to 30.0) (log rank p = 0.22), and risk for development of microalbuminuria was not associated with year of onset of diabetes (hazard ratio 1.05 (0.99 to 1.12), p = 0.11). In groups C versus B versus A, glycaemic control improved after 10 years of diabetes (mean HbA1c 8.9% (1.5%) vs 9.4% (1.5%) vs 10.1% (1.7%), p value for ANOVA <0.001) and more children achieved an HbA1c level <7.5% (15.6% vs 5.9% vs 6.1%, p value for ANOVA = 0.032). CONCLUSION In this UK based inception cohort of children diagnosed with type 1 diabetes, the adjusted prevalence of microalbuminuria was unchanged since 1986, despite some improvements in glycaemic control. This observation highlights the need for more proactive intervention with drugs such as angiotensin converting enzyme (ACE) inhibitors.

Abstract
Hepatocellular carcinoma (HCC) is the third leading cause of cancer deaths worldwide, with few effective therapeutic options for advanced disease. At least 40% of HCCs are clonal, potentially arising from STAT3+, NANOG+ and OCT3/4+ liver progenitor/stem cell transformation, along with inactivation of transforming growth factor-beta (TGF-beta) signaling. Here we report significantly greater signal transducer and activator of transcription 3 (STAT3) and tyrosine phosphorylated STAT3 in human HCC tissues (P<0.0030 and P<0.0455, respectively) than in human normal liver. Further, in HCC cells with loss of response to TGF-beta, NSC 74859, a STAT3-specific inhibitor, markedly suppresses growth. In contrast, CD133(+) status did not affect the response to STAT3 inhibition: both CD133(+) Huh-7 cells and CD133(-) Huh-7 cells are equally sensitive to NSC 74859 treatment and STAT3 inhibition, with an IC(50) of 100 muM. Thus, the TGF-beta/beta2 spectrin (beta2SP) pathway may reflect a more functional 'stem/progenitor' state than CD133. Furthermore, NSC 74859 treatment of Huh-7 xenografts in nude mice significantly retarded tumor growth, with an effective dose of only 5 mg/kg. Moreover, NSC 74859 inhibited tyrosine phosphorylation of STAT3 in HCC cells in vivo. We conclude that inhibiting interleukin 6 (IL6)/STAT3 in HCCs with inactivation of the TGF-beta/beta2SP pathway is an effective approach in management of HCCs. Thus, IL6/STAT3, a major signaling pathway in HCC stem cell renewal and proliferation, can provide a novel approach to the treatment of specific HCCs.

Abstract
We present a LIGO search for short-duration gravitational waves (GWs) associated with soft gamma ray repeater (SGR) bursts. This is the first search sensitive to neutron star f modes, usually considered the most efficient GW emitting modes. We find no evidence of GWs associated with any SGR burst in a sample consisting of the 27 Dec. 2004 giant flare from SGR 1806-20 and 190 lesser events from SGR 1806-20 and SGR 1900+14. The unprecedented sensitivity of the detectors allows us to set the most stringent limits on transient GW amplitudes published to date. We find upper limit estimates on the model-dependent isotropic GW emission energies (at a nominal distance of 10 kpc) between 3x10;{45} and 9x10;{52} erg depending on waveform type, detector antenna factors and noise characteristics at the time of the burst. These upper limits are within the theoretically predicted range of some SGR models.

Abstract
INTRODUCTION The presence of an ectopic posterior pituitary gland (EPP) on magnetic resonance imaging (MRI) is associated with hypopituitarism with one or more hormone deficiencies. We aimed to identify risk factors for having multiple pituitary hormone deficiency (MPHD) compared to isolated growth hormone deficiency (IGHD) in patients with an EPP. METHODS In 67 patients (45 male) with an EPP on MRI, the site (hypothalamic vs. stalk) and surface area (SA) [ x (maximum diameter/2) x (maximum height/2), mm(2)] of the EPP were recorded and compared in patients with IGHD and MPHD in relation to clinical characteristics. RESULTS In MPHD (n = 32) compared to IGHD (n = 35) patients: age of presentation was younger (1.4 [0.1-10.7]vs. 4.0 [0.1-11.3] years, P = 0.005), major incidents during pregnancy were increased (47%vs. 20%, P = 0.02) as were admissions to a neonatal intensive care unit (NICU) (60%vs. 26%, P = 0.04), whilst EPP SA was lower (12.3 [2.4-34.6]vs. 25.7 [6.9-48.2] mm(2), P < 0.001). In patients with a hypothalamic (n = 56) compared to a stalk sited EPP (n = 11): prevalence of MPHD was greater (55%vs. 9%,P = 0.05) and EPP surface area was smaller (17.3 [2.4-48.2]vs. 25.3 [11.8-38.5] mm(2), P < 0.001). In regression analysis, after adjusting for age, presence of MPHD was associated with: major incidents during pregnancy (RR 6.8 [95%CI 1.2-37.7]), hypothalamic EPP site (RR 10.9 [1.0-123.9]) and small EPP SA (RR 2.5 [1.0-5.0] for tertiles of SA). CONCLUSION In patients with an EPP, adverse antenatal events, size (small) and position (hypothalamic) of the posterior pituitary gland on MRI were associated with MPHD. These findings suggest that adverse factors during pregnancy may be important for the development of an EPP.

The development of microalbuminuria is associated with raised longitudinal adiponectin levels in female but not male adolescent patients with type 1 diabetes. Diabetologia 2008; 51:1707-13. [PMID: 18622594 DOI: 10.1007/s00125-008-1081-1] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/12/2008] [Accepted: 05/30/2008] [Indexed: 01/25/2023]
Abstract
AIMS/HYPOTHESIS We determined the longitudinal relationship between adiponectin levels and the development of microalbuminuria in an inception cohort of children with type 1 diabetes. METHODS Blood samples collected annually over a median of 9.0 (range 1.3-14.9) years were assayed for adiponectin and HbA(1c) in 55 children (36 girls) with type 1 diabetes and microalbuminuria whose age of onset of diabetes was 9.4 years (range 2.2-15.4). Samples were also assayed from normoalbuminuric children (controls) matched for age, sex and duration of diabetes. RESULTS Overall, adiponectin levels were higher in girls than in boys, but only after 11 years of age (median [range]: 15.3 [5.8-124.4] vs 11.6 [4.1-26.5] mg/l, p < 0.001). Furthermore, adiponectin levels were higher in girls with microalbuminuria than in control girls, but this was only apparent after the onset of microalbuminuria (p = 0.001, adjusted for BMI, daily insulin dose, HbA(1c) and age). In boys, adiponectin levels did not differ between those with microalbuminuria and controls. Further sex-related discordant associations with adiponectin levels were observed; in girls, adiponectin levels were positively related to HbA(1c) levels (r = 0.2, p = 0.05) and urine albumin excretion (r = 0.3, p < 0.05) and inversely related to BMI (r = -0.2, p < 0.05). These associations were absent in boys. CONCLUSIONS/INTERPRETATION In adolescent girls with type 1 diabetes but not in boys, adiponectin levels increase with increasing urine albumin excretion and onset of microalbuminuria. Although causal links cannot be inferred, this sexual dimorphism may reflect interactive effects of hyperglycaemia and sex steroids on risk of complications and adiponectin production.
