Objective

To assess the antioxidant vitamins A (retinol) and E (α-tocopherol) levels, iron status and growth retardation in children with β-thalassemia major in Odisha, an eastern state of India.

Methods

Forty three children aged 1–15 y diagnosed with β-thalassemia major (28 males and 15 females) and 42 age-matched healthy controls (22 males and 20 females) were studied. β-thalassemia was detected by using Bio-rad variant assay. Measurement of blood hemoglobin (Hb), hematocrit, serum vitamins (A and E) and ferritin was carried out by standard methods.

Results

Mean hemoglobin (6.60?±?1.84 vs. 11.8?±?2.29 g/dL, p?<?0.01), serum retinol (28.0?±?17.67 vs. 54.4?±?36.56 μg/dL, p?<?0.001) and α-tocopherol (0.2?±?0.34 vs. 1.1?±?0.82 mg/dL, p?<?0.001) were significantly lower in children with thalassemia compared with control group, however, serum ferritin (storage iron) was elevated in thalassemia patients (553.7?±?176.80 vs. 57.3?±?40.73 ng/mL, p?<?0.001). Vitamin E had significantly correlated with hemoglobin and hematocrit values in the patients. Growth retardation in terms of stunting (79 % vs. 24 %, p?<?0.0001) and thinness (32.6 % vs. 9.5 %, p?<?0.05) was significantly higher in thalassemic children compared with normal children.

Conclusions

This study shows that children with β-thalas-semia major are in a state of oxidative stress of hyperfer-ritinemia with deprived antioxidant vitamins (A and E) and poor growth status suggesting a possible need for reduction in iron overload and additional antioxidant supplementation.  相似文献

Objective

To study the effect of oil massage on growth in preterm babies less than 1800 g.

Methods

This randomised controlled trial was conducted in Neonatal intensive care unit of a level II hospital. Neonates with birth weight?<?1800 g, gestation?<?35 wk and?<?48 h of age at enrolment were included in the studies. Eligible neonates were randomized to one of the two groups (a) Oil massage along with standard care of low birth weight (b) Standard care of low birth weight without massage. Weight, length and head circumference was measured in the two groups at 7 d intervals. Serum triglyceride levels were measured at enrolment and at completion of study. Primary outcome variable was weight gain at 28 d after enrolment.

Results

A total of forty-eight neonates were randomisd to either oil massage group (n?=?25) or standard care of low birth weight without massage group (n?=?23). Mean (SD) weight of babies in the two groups was 1466.4?±?226.8 g in oil massage group and 1416.6?±?229.9 g in the control group. At 28 d, weight gain in the oil massage group (476.76?±?47.9 g) was higher compared to the control group (334.96?±?46.4 g) (p?<?0.05). At 7 d, less weight loss (7.80?±?9.8 g) was observed in babies in oil massage group compared to control group (21.52?±?19.4 g) (p?=?0.003). However, there was no significant difference in serum triglycerides and other anthropometric parameters.

Conclusions

Oil application has a potential to improve weight gain and cause less weight loss in first 7 d in low birth weight neonates  相似文献

Objective

To compare the fat content and contamination of expressed breast milk (EBM) before and after storage (30 d) in hard polypropylene containers (HC) and soft polyethylene bags (SB) containers.

Methods

Ninety specimens of EBM were collected into HC and separated into two HC and two SB. The fat content of each specimen of EBM in HC and SB was measured and cultures were performed. The specimens in the second HC and SB containers were kept frozen for 30 d before thawing and then measuring the fat content and performing cultures.

Results

The means ± SD of the fat content of fresh and thawed EBM in HC were 2.98?±?0.97 and 2.66?±?0.88 g/100 ml, respectively, with a loss of 0.32 g/100 ml (p?<?0.001). The means ± SD of the fat content of fresh and thawed EBM in SB were 3.06?±?1.00 and 2.77?±?0.91 g/100 ml, respectively, with a mean loss of 0.29 g/100 ml during storage (p?<?0.001). The loss of fat content during frozen storage did not differ significantly between the two types of containers (p?=?0.53). All bacterial cultures of fresh and thawed EBM in HC and SB showed only nonpathogenic organisms.

Conclusions

SB can replace HC for the long-term storage of frozen EBM of up to 30 d without deleterious effects on fat loss or contamination.  相似文献

Objective

To determine whether serum fructosamine which is a good marker for detecting hyperglycemia during the previous 2 to 3 wk in infants could predict the development of retinopathy of prematurity in very low birth weight infants.

Methods

One hundred sixty seven premature infants who had a birth weight of <1500 g and a gestational age of less than 32 wk were investigated in the present study. Blood glucose was measured at the bedside and infants were recorded as hyperglycemic if their mean blood glucose levels were higher than 150 mg/dL. Serum corrected fructosamine level was obtained from the cord blood at birth and after the first month of life. The infants’ eyes were examined by ophthalmologists to detect retinopathy of prematurity at the gestational age of 32 wk or at four wk after birth, whichever came first.

Results

Corrected fructosamine was 319.6?±?59.6 and 272.8?±?50.6 mmol/l for group1 on 1st and 30th day respectively; 320?±?61.7 and 268.2?±?47.3 mmol/l for groups 2?+?3 on 1st and 30th day respectively which did not differ between groups (p?=?0.766 and p?=?0.665), whereas duration of hyperglycemia was 1.69?±?1.1 day in group 1 compared with 3.05?±?2.4 day in groups 2?+?3 which was significantly different (p?=?0.019). The multivariate regression analysis indicated that the duration of hyperglycemia in days was significantly correlated with the development of retinopathy of prematurity (OR 3.26; 95% CI 1.09–9.80; p?=?0.035).

Conclusions

Although the duration of hyperglycemia may contribute to the development of retinopathy of prematurity, serum corrected fructosamine does not have a good predictive value in developing retinopathy of prematurity in very-low-birth-weight (VLBW) infants.  相似文献

Background/aim

Sodium is thought to be critical to growth. Infants who have an ileostomy may suffer from growth faltering, as sodium losses from stomas may be excessive. Urinary sodium measurements may indicate which patients could benefit from sodium supplementation; however, there is no consensus on what level of urinary sodium should be the cutoff for intervention. Our aim was to determine whether there is a relationship between urinary sodium and growth in infants undergoing ileostomy, colostomy and cystostomy.

Methods

Following audit approval, a retrospective observational study of patient notes and chemical pathology data was carried out. All infants <1 year of age that had an ileostomy, colostomy, or cystostomy procedure between February 1997 and January 2014 were included. Patients’ weights, urinary and serum sodium and potassium levels and clinical variables were recorded until discharge. Weights were converted to Z-scores for analysis.

Results

Forty patients were identified whose notes were available for review and who had at least three urinary sodium measurements. During their hospital stay, 11 (28 %) maintained weight within normal limits (Z-scores ?2 to +2, 15 (38 %) were moderately malnourished (?3 to ?2) and 14 (35 %) severely malnourished (30 mmol litre. Electrolyte data were not normally distributed so that correlations between electrolytes and growth were tested using the non-parametric Spearman rank correlation coefficient. Urinary sodium levels positively correlated with growth (r = 0.3071, p < 0.0001), as did serum sodium levels (r = 0.2620, p = 0.0059) whereas there was no relationship between urine or serum potassium and growth.

Conclusions

Poor growth is frequent in this group of patients and appears to be linked with sodium levels. Further work is necessary to draw up guidelines for appropriate sodium supplementation.  相似文献

Objective

To determine outcome of children receiving carvedilol in addition to other standard drug therapy for treatment of dilated cardiomyopathy.

Methods

Children receiving carvedilol for treatment of dilated cardiomyopathy with moderate to severe ventricular dysfunction were included into the study. Data on history, clinical examination and investigations were obtained and detailed echocardiography findings were recorded for the initial and all subsequent visits.

Results

Thirty-three children, mean age 26?±?30 mo (range 7 mo to 138 mo) were enrolled. Carvedilol was initiated at a mean dose of 0.14?±?0.03 mg/kg/d and the maintenance dose was 0.46?±?0.14 mg/kg/d. At a follow up of 6–90 mo (mean of 28?±?23 mo), functional class using Ross classification for pediatric heart failure improved from 2.7 to 1.3. The left ventricular ejection fraction rose from a basal value of 22 %?±?7 % (10–40 %) to 42 %?±?15 % (15–65 %) (p?<?0.0001). Similarly, left ventricular fractional shortening increased significantly from 16?±?6 % (8–34 %) to 21?±?7 % (10–44 %) (p?<?0.0001). One patient deteriorated and died of refractory heart failure. Carvedilol was discontinued in two more patients temporarily due to bronchospasm during respiratory infection.

Conclusions

The present study suggests that improvement in ventricular function and clinical symptoms is seen on oral carvedilol added to standard drug therapy in pediatric patients with dilated cardiomyopathy and moderate to severe ventricular dysfunction. The drug is well tolerated with minimal side effects but close monitoring is required as it may worsen heart failure and bronchospasm.  相似文献

Purpose

Early ultrasound (US) evaluation of children with abdominal pain and suspected acute appendicitis (AA) is an important diagnostic tool. Since 2007, US has become part of routine emergency room (ER) work-up performed for suspected pediatric AA in our hospital.

Methods

We retrospectively compared hospital admissions from 2007 to 2008 with those from 2005 to 2006, when most ultrasounds were done after admission to Pediatric Surgery for observation.

Results

During the study (2005?C2008), 6,511 children came to the ER with acute abdominal pain. Although pediatric ER sonography increased from 28.1% (865/3,079) in 2005?C2006 to 51.7% (1,775/3,432) in 2007?C2008 (p?<?0.0001), hospitalizations decreased from 33 to 30.1% (p?=?0.011). Concurrently, ER US for AA increased from 20.8% (639/2,440) to 38.9% (1,336/2,096) (p?<?0.0001), admissions for suspected AA decreased from 51.8% (331/639) to 42% (561/1,336) (p?<?0.0001).

Conclusions

Sonography led to a significant decline in admissions and better selection of patients who required surgery for AA. Recurrent ER referrals for the same complaint within 2?weeks was very low (2.9%) with no difference between the two study periods (p?=?1); none had AA. These findings encourage us to continue early US in children with suspected AA. This effective tool decreases unnecessary hospital stays, investigative procedures, and surgery, while reducing costs.  相似文献

Purpose

The purpose was to compare the resource utilization and outcomes between patients with suspected (SUSP) and confirmed (CONF) non-accidental trauma (NAT).

Methods

The institutional trauma registry was reviewed for patients aged 0–18 years presenting from 2007 to 2012 with a diagnosis of suspicion for NAT. Patients with suspected and confirmed NAT were compared.

Results

There were 281 patients included. CONF presented with a higher heart rate (142?±?27 vs 128?±?23 bpm, p?<?0.01), lower systolic blood pressure (100?±?18 vs 105?±?16 mm Hg, p?=?0.03), and higher Injury Severity Score (15?±?11 vs 9?±?5, p?<?0.01). SUSP received fewer consultations (1.6?±?0.7 vs 2.4?±?1.1, 95% CI ? 0.58 to ? 0.09, p?<?0.01) and had a shorter length of stay (1.6?±?1.3 vs 7.8?±?9.8 days, 95% CI ? 4.58 to ? 0.72, p?<?0.01). SUSP were more often discharged home (OR 94.22, 95% CI: 21.26–417.476, p?<?0.01). CONF had a higher mortality rate (8.2 vs 0%, p?<?0.01).

Conclusions

Patients with confirmed NAT present with more severe injuries and require more hospital resources compared to patients in whom NAT is suspected and ruled out.

Objective

To determine the prooxidant-antioxidant balance (PAB) in neonatal asphyxia and compare it with values for PAB in healthy neonates.

Methods

In a prospective observational study, serum PAB of umbilical cord blood of 30 neonates with asphyxia [pH <?7.2, low Apgar score, signs of respiratory distress syndrome (RDS)] as the case group and 35 healthy neonates (without an abnormal clinical event at birth and after the first week) as the control group were compared.

Results

Among the 35 neonates in the control group, the average level of serum PAB was 20.00 HK units, which was significantly lower than for the 30 neonates within the case group (40.46 HK units; p?=?0.019). The blood pH in the case group was significantly lower than for control group (P?<?0.001). In controls, HCO3 - and pCO2 were 18.6 mmol/L and 38.5 mmHg respectively, whilst in the case group these values were 15.5 mmol/L and 45.7 mmHg respectively (p?<?0.05).

Conclusions

Determination of PAB may be useful in the early diagnosis of perinatal asphyxia and is consistent with HCO3 -, pCO2 and Apgar score.  相似文献

Objective

To determine changes in body temperature (BT) of hyperbilirubinemic newborns under conventional phototherapy with fluorescent lamps and light emitting diodes (LED) at different irradiances.

Methods

Otherwise healthy newborn infants >34 wk gestational age (GA) hospitalized for indirect hyperbilirubinemia, requiring phototherapy in the first 10 d of life were enroled. Infants who received conventional phototherapy with fluorescent lamps (10–15 μW/cm2/nm irradiance) were defined as group 1, LED phototherapy of 26–60 μW/cm2/nm irradiance as group 2, and LED phototherapy of 60–120 μW/cm2/nm irradiance as group 3. Primary outcome measure was mean BT which was defined as arithmetical mean of axillary BT measured at 2 h intervals during the first day of phototherapy.

Results

Thirty patients were enroled in each group. Mean birth weight and GA of the total cohort was 2800?±?530 g and 36.6?±?2 wk, respectively. Baseline demographic variables and serum total bilirubin levels were similar among groups. Mean BT was 36.7?±?0.1 °C in group 1, 36.6?±?0.2 °C in group 2, 37.7?±?0.2 °C in group 3. Mean BT was higher in group 3 compared to group 1 (p?<?0.001) and group 2 (p?<?0.001). Group 1 and group 2 had similar mean BT measurements (p?=?0.09). During phototherapy all the patients in group 3 had at least one BT measurement ≥37.5 °C and 77 % had BT ≥38 °C. Only one patient in group 2 had BT?≥?37.5 °C which was also ≥38 °C. During phototherapy all BT measurements were <37.5 °C in group 1.

Conclusions

LED phototherapy of ≥60 μW/cm2/nm intensity significantly increases BT in hyperbilirubinemic newborns.  相似文献

Objective

To compare the characteristics of jaundice and hyperbilirubinemia in the newborn population of both immigrant and Italian mothers.

Methods

The authors studied a group of 1,680 infants born at “A. Gemelli” hospital during 1 y. All were with appropriate weight for gestational age, weighting more than 2,500 g, born to low-risk pregnancy. Maternal ethnicity, clinically evident jaundice (that is total serum bilirubin (TSB)?>?7 mg/dL), hyperbilirubinemia (TSB?>?12 mg/dL), the duration of hospital stay and their need of phototherapy were evaluated.

Results

In infants born to Asian mothers, hyperbilirubinemia was significantly more frequent (48.8 % vs. 26.5 %, p?=?0.003) and they reached mean TSB peak significantly later (86.5?±?38.5 vs. 74.5?±?20.6 h, P?=?0.0001) compared with Italian infants. The average length of hospitalization of infants of Asian and Latin American mothers is significantly longer compared to Italian newborns (4.5?±?1.9 vs. 3.6?±?1.1, p <0.0001 and 4.2?±?1.6 vs. 3.6?±?1.1, p?=?0.0004). With regard to the use of phototherapy, and to its duration, there are no significant differences between the populations studied.

Conclusions

Having studied all infants at low risk, the greater length of hospitalization is due to later peak and the higher frequency of jaundice in newborns of immigrant mother, especially in Asia. Therefore, as it happens to the Italian newborns, it would be desirable to build forecasting nomograms in these populations, to reduce the length of hospitalization and facilitate protected discharge.  相似文献

Objective

To investigate the longitudinal changes in amino acid (AA) and acylcarnitine (AC) profiles of preterm neonates over the first 2 wk of life, and to detect any significant deviation from full term values that requires change of cut-off values used for detection of metabolic disorders in preterm neonates.

Methods

This observational analytical longitudinal study was conducted on 131 premature neonates (gestational age ranged from 27 to 36 wk) and 143 healthy full-term neonates. Dried blood spots were taken on the 5th and 14th postnatal day from the premature neonates and on day 5 from full term neonates for neonatal screening. Samples were analyzed for AA and AC using tandem mass spectrometer.

Results

Most AA significantly decreased on day 14 compared to day 5 among preterm neonates (p?<?0.05). The combined values of total carnitine (TC), total acylcarnitine (tAC) and short-chain acylcarnitines on day 5 among preterm neonates were statistically significantly higher compared to the day 14 sample (p 0.0001), whereas no statistically significant difference was found regarding the values of medium-, long-chain acylcarnitines, tAC/FC, and FC/TC (p?>?0.05). The levels of AA of preterm neonates were statistically significantly higher than that of the controls (p?<?0.05). The values of TC, tAC, short-, medium- and long-chain acylcarnitines, were significantly higher than those of the controls (p?<?0.05). The reference ranges for preterm neonates were determined using the 1st and 99.9th percentiles.

Conclusions

AA and AC showed an age-related distribution of their concentrations. This underlines the importance of using appropriate reference values when working with a prematurely born population.  相似文献

Objectives

To assess the behavior of pregnant women regarding neonatal care. Also to implement and assess impact of Behaviour Change Communication (BCC) package among pregnant women regarding neonatal care.

Methods

This community based intervention study was conducted in field practice area of Urban Health Training Centre (UHTC), Department of Community Medicine, Jawaharlal Nehru Medical College and Hospital (JNMCH), Aligarh Muslim University (A.M.U), Aligarh (UP), India. Two hundred pregnant women were included. Epi Info version 3.5.1. Percentages, and Chi square test were used for statistical analysis.

Results

Due to implementation of BCC package, institutional deliveries improved (RR?=?2.47, P?<?0.05), delivery practices significantly increased (RR?=?2.47, P?<?0.05). There was significant difference regarding breastfeeding practices on 7th and 28th d of delivery. More (80 %) deliveries were conducted in warm room (RR?=?1.87, p?<?0.05), bathing to the baby was delayed (RR?=?0.81, p?<?0.05) and decreased, vigorous removal of vernix caseosa was observed (RR?=?0.45, p?<?0.05). Correct knowledge about danger signs and physiological conditions in newborns were increased (RR?=?2.5.0, p?<?0.05 for cold to touch, RR?=?1.22, p?<?0.05 for peeling of skin).

Conclusions

There was a significant impact of BCC package on the behavior of pregnant women regarding neonatal care.  相似文献

Objective

To evaluate the role of serum procalcitonin (PCT) in diagnosis of septic meningitis in children and its efficacy in differential diagnosis.

Methods

The study included 40 children of septic meningitis admitted in pediatric ward with fever, headache, vomiting and seizure, up to 14 y of age. The diagnosis of septic meningitis was based on clinical features; physical examination, blood and cerebrospinal fluid (CSF) cytochemical findings, gram’s stain and bacterial culture. Fifteen cases of aseptic meningitis admitted during same period were also included in the study, and 15 children with normal CSF were taken as control. Serum PCT was measured by ELISA Kit.

Results

Serum PCT level was significantly higher in children with septic meningitis than those with aseptic meningitis or in controls (p?<?0.001). In culture and gram’s stain positive 7 cases, serum procalcitonin was significantly elevated (24,768.21?±?6,567.45 pg/mL) than aseptic meningitis(14,451.24?±?4,266.15 pg/mL) (p?<?0.001). Further its level was found significantly elevated in partially treated septic meningitis as compared to aseptic meningitis cases (p?<?0.001). At optimum cut off value of ≥ 5,000 pg/mL, based on area under ROC curve, PCT showed sensitivity, specificity, positive predictive value and negative predictive value of 98.5 %, 93.5 %, 98.6 % and 93.3 % respectively. Serum PCT with cut off level of 15,000 pg/ml showed sensitivity, specificity, PPV and NPV of 92 %, 67 %, 91.4 % and 71.4 % respectively for the differentiation of septic from aseptic meningitis.

Conclusions

Serum PCT may be used as diagnostic marker for septic meningitis and its differentiation from aseptic meningitis.  相似文献

Objective

To evaluate the changes in the LV systolic and diastolic function in children with beta-thalassemia major (β-TM) using pulsed wave tissue doppler (TD) echocardiography.

Methods

Clinical, conventional echo doppler and pulsed wave tissue doppler imaging parameters were compared in 40 beta-thalassemia major patients (mean age, 6.52?±?3.5 y) and 25 age and sex matched normal subjects (mean age, 6.5?±?2.7 y).

Results

There were no significant statistical differences between mean fractional shortening (FS) and ejection fraction (EF) of left ventricle (LV) of the patients and control group. Children with beta-thalassemia had significantly lower E′ wave velocities measured at the left ventricular septal annulus (8.1?±?3.3 vs. 13?±?2.5, P?<?0.001), lateral margin of the mitral annulus (9.1?±?5.4 vs. 13.3?±?2.5, P?<?0.001) and lateral margin of the tricuspid annulus (9.3?±?3.9 vs. 13.3?±?2.5, P?<?0.001) when compared to the control group. Furthermore children with beta-thalassemia had significantly lower E′/A′ wave ratio at the left ventricular septal annulus (0.76?±?0.34 vs. 1.36?±?0.23), lateral margin of the mitral annulus (0.83?±?0.17 vs. 1.28?±?0.22), and lateral margin of the tricuspid annulus ((0.90?±?0.27 vs. 1.26?±?0.23, (P?<?0.05) when compared to the control group.

Conclusions

This study showed that patients with beta-thalassemia major and normal conventional echo doppler parameters had statistically significant changes detected by pulsed wave tissue doppler imaging.  相似文献

Objectives

To evaluate if cardiac dysfunctions are important in assessing the outcome in newborns with Bronchopulmonary Dysplasia (BPD), by evaluating cardiac functions with N-terminal prohormone of brain natriüretic peptide (NT-proBNP) levels, M-mode and tissue doppler echocardiography at 6–12 mo of age.

Methods

Twenty eight patients were retrospectively classified as mild, moderate and severe according to the diagnostic criterias for BPD. All cases were assessed with standard M-mode, tissue doppler echocardiography and NT-proBNP levels. Control group consisted of 28 healthy infants, having similar postnatal ages as patients and were assessed with standard M-mode and tissue doppler echocardiography.

Results

The age of patients with BPD was 9.8?±?2.3 mo and control group was 9.5?±?2.6 mo. There was no significant difference between the postnatal ages of two groups (p?>?0.05). Neither pulmonary hypertension nor pulmonary/tricuspid regurgitation was detected. The M-mode echocardiography measurements did not differ between patients and control group (p?>?0.05). Tissue doppler echocardiography, tricuspid valve medial segment early diastolic myocardial relaxation velocity (TME’) measurements of patients were found significantly lower, peak transtricuspid filling velocity in the early diastole (TE)/TME’ ratios and isovolumetric relaxation time (IVRT) measurements were found significantly higher than control group (p?<?0.05). Tricuspid E, TE/TLE’ (Tricuspid valve lateral segment early diastolic myocardial relaxation velocity), TE/RVLE’(Right ventricular lateral segment early diastolic myocardial relaxation velocity), TE/TME’ levels were also found as significantly abnormal in patients with severe BPD. A significant correlation was found between right ventricular diastolic disfunctions and severity of BPD (p?<?0.05). No statistically significant difference was found between NT-proBNP levels, BPD stages and tissue doppler echocardiography measurements (p?>?0.05).

Conclusions

This is the first study evaluating cardiac findings in patients with BPD by tissue doppler echocardiography and NT-proBNP at the same time. On the basis of cardiac evaluations, tissue doppler echocardiography measurements were found as significant and specific for the early assessment of right ventricular diastolic disfunctions.  相似文献

Objectives

To determine the effect of Kangaroo Mother Care (KMC) of small duration of 15 min in decreasing pain in preterm neonates between 32–36 wk 6 d on heel prick by a 26 gauge needle.

Methods

Randomized controlled double masked crossover trial involving 50 neonates, between 32 wk and 36 wk 6 d gestation and weighing less than 2500 g, within 10 d of birth, vitally stable, breathing without assistance or on Continuous positive airway pressure (CPAP), without any clinically evident neurological signs, not having received analgesics/sedatives within last 24 h and not fed within last 30 min and requiring heel pricking were eligible. Outcome measured was the Premature Infant Pain Profile (PIPP). Analysis was done using independent sample t test, with Bonferroni correction applied for comparing individual components of PIPP score.

Results

The heart rate, behaviour and facial scores were statistically significant and lower in KMC group. But there was no statistically significant difference in oxygen saturation (SpO2). The difference(4.85) in PIPP score was clinically and statistically significant (p?<?0.0001).

Conclusions

The findings suggest that short duration KMC (15 min) has stress reducing benefits. Preterm neonates above 32 wk gestational age can benefit from KMC to decrease pain from heel prick procedure.  相似文献

Smith–Lemli–Opitz syndrome (SLOS), a multiple congenital anomaly with severe mental retardation, is caused by decreased activity of 7-dehydrocholesterol reductase. Fifteen Hungarian patients were diagnosed with SLOS on the basis of clinical symptoms, serum cholesterol, 7-dehydrocholesterol, and molecular genetic testing. Their age at the time of diagnosis in mild SLOS (n?=?4, clinical score <20) was 0.5–18 years, cholesterol was 2.37?±?0.8 mmol/L, and 7DHC was 0.38?±?0.14 mmol/L. In the group of typical SLOS (n?=?7, score 20–50), the diagnosis was set up earlier (age of 0.1–7 years); t-cholesterol was 1.47?±?0.7 mmol/L, and 7DHC was 0.53?±?0.20 mmol/L. Patients with severe SLOS (n?=?4, clinical score?>?50) died as newborns and had the lowest t-cholesterol (0.66?±?0.27 mmol/L), and 7DHC was 0.47?±?0.14 mmol/L. Correlation coefficient with clinical severity was 0.74 for initial t-cholesterol and 0.669 for Cho/7DHC. Statistically significant difference was between the initial t-cholesterol of mild and severe SLOS (p?=?0.01), and between the Cho/7DHC ratios of groups (p?=?0.004). In severe SLOS, the percentage of α-lipoprotein was significantly lower than in typical (p?=?0.003) and mild SLOS (p?=?0.004). Although serum albumin, total bilirubin, and hemostasis parameters remained in the reference range during cholesterol supplementation (n?=?10) combined with statin therapy (n?=?9), increase of aspartate aminotransferase and alanine aminotransferase in 50 % of the patients probably refers to a reversible alteration of liver function; therefore, statin therapy was suspended. Conclusion: life expectancy is fundamentally determined by the initial t-cholesterol, but dehydrocholesterol and α-lipoprotein have prognostic value. Accumulation of hepatotoxic DHC may inhibit the synthesis of α-lipoproteins, decreasing the reverse cholesterol transport. During statin therapy, we suggest monitoring of lipid parameters and liver function.  相似文献

Objective

Pulmonary arterial hypertension (PAH) is a dysfunctional endothelium disease with increased pulmonary vascular resistance (PVR) and poor prognosis. Current therapies are still insufficient. Here we propose a new pulsatile device as a more effective tool for PAH management compared with traditional treatments.

Materials and Methods

Twelve piglets (10.3?±?3.8?kg) were given either intrapulmonary pulsatile [P (n?=?6)] or nonpulsatile [NP (n?=?6)] tadalafil treatment. After median sternotomy and heparin injection (250?IU/kg), both groups underwent aorto-pulmonary surgical shunt for 1?h. During a second 1?h period in group P, a catheter prototype, driven by a small ventilator, was introduced into the pulmonary trunk and pulsated intermittently at 110?bpm irrespective of heart rate (90.6?±?10.74 bpm). In group NP, tadalafil was given orally (1?mg/kg).

Results

Hemodynamics and cardiac output (CO) were significantly (p?<?0.05) improved in group P compared with group NP: CO was 0.56?±?0.0.26 versus 0.54?±?0.11 (L/min), respectively. Mean pulmonary artery pressure (PAP) was decreased in group P compared with group NP: PAP was 9.6?±?2.97 versus 32.2?±?5.07, respectively. Vascular resistances (dynes.s.cm?5/kg) were significantly lower in group P versus group NP: pulmonary resistance was 85?±?42.12 versus 478?±?192.91 and systemic resistance was 298.8?±?172.85 versus 1301?±?615.79, respectively. Using Western blot analysis, endogenous NO synthase expression in PA segments was nonsignificantly (p?>?0.05) greater in group P (0.81?±?0.78) versus (0.62?±?0.35) group NP.

Conclusion

Induced with an appropriate device, intrapulmonary shear stress?Cmediated endothelial function enhancement provides a more effective nearly physiological therapy for PAH.  相似文献

Background

Organ-specific dose reduction significantly reduces the radiation exposure of radiosensitive organs.

Objective

The purpose of this study was to assess the impact of a novel organ-specific dose reduction algorithm on image quality of pediatric chest CT.

Materials and methods

We included 28 children (mean age 10.9?±?4.8 years, range 3–18 years) who had contrast-enhanced chest CT on a 128-row scanner. CT was performed at 100 kV using automated tube current modulation and a novel organ-specific dose-reduction algorithm (XCare?; Siemens, Forchheim, Germany). Seven children had a previous chest CT performed on a 64-row scanner at 100 kV without organ-specific dose reduction. Subjective image quality was assessed using a five-point scale (1-not diagnostic; 5-excellent). Contrast-to-noise ratio (CNR) and signal-to-noise ratio (SNR) were assessed in the descending aorta.

Results

Overall mean subjective image quality was 4.1?±?0.6. In the subgroup of the seven children examined both with and without organ-specific dose reduction, subjective image quality was comparable (score 4.4?±?0.5 with organ-specific dose reduction vs. 4.4?±?0.7 without it; P?>?0.05). There was no significant difference in mean signal-to-noise ratio and contrast-to-noise ratio with organ-specific dose reduction (38.3?±?10.1 and 28.5?±?8.7, respectively) and without the reduction (35.5?±?8.5 and 26.5?±?7.8, respectively) (P?>?0.05). Volume computed tomography dose index (CTDIvol) and size-specific dose estimates did not differ significantly between acquisitions with the organ-specific dose reduction (1.7?±?0.8 mGy) and without the reduction (1.7?±?0.8 mGy) (P?>?0.05).

Conclusion

Organ-specific dose reduction does not have an impact on image quality of pediatric chest CT and can therefore be used in clinical practice to reduce radiation dose of radiosensitive organs such as breast and thyroid gland.  相似文献
