ABSTRACT

BACKGROUND: Malnutrition presents a major global health burden. In Egypt, it remains an important issue in children under 5 years especially in rural communities. AIM OF THE STUDY: The aim of the study was to screen 2-5 years old children enrolled from Egyptian hospitals in rural and urban areas for the risk of malnutrition using Screening Tool for Assessment of Malnutrition in Pediatric (STAMP) and to evaluate the effectiveness of nutritional intervention programs. SUBJECTS AND METHODS: This cross-sectional study was conducted on 90 patients recruited from two hospitals in urban and rural Cairo, Dietary history and anthropometric measurements were assessed. Patients at intermediate and severe risk of malnutrition according to STAMP were given tailored nutritional programs. RESULTS: In the rural hospital, 4.4% of the screened children were underweight, 22.2% were marginally underweight, and 73.3% had normal weight. Regarding the urban hospital, 15.6% were marginally underweight, 84.4% had normal weight and no underweight patients. Among the rural group 35.6% were at high risk according to STAMP score results compared to 20% in the urban group. Nevertheless, the only significant differences were the more stunting and higher BMI in rural hospital patients. After nutritional intervention, high-risk category patients decreased in both groups coupled by significant improvement in the anthropometric parameters and nutrition data with no significant differences between them. CONCLUSION: Nutritional education and prompt implementation of nutritional rehabilitation program for malnourished children detected by screening tools result in improvement in their nutritional status disregards their location whether urban or rural.

ABSTRACT

We report the result of treatment of 69 complex clasped thumbs in 39 patients with distal arthrogryposis. The mean age at surgery was 30 months. Surgical reconstruction included skin augmentation of the first web using modified dorsal rotation advancement flap (Abdel-Ghani flap), a la Carte release of tight structures of the first web, and chondrodesis of the thumb metacarpophalangeal joint. The mean follow-up was 4 years. We prefer chondrodesis because of the presence of global instability, abnormal joint structure, abnormal articular surfaces, and inefficient muscles for transfer. Also, chondrodesis shortens the thumb and may alleviate the need for release of deficient palmar skin and lengthening of a short flexor pollicis longus. The Abdel-Ghani flap provides ample skin that gives a wide rounded web. It is a simple procedure with minimal donor site morbidity. Surgical reconstruction significantly improved the cosmetic appearance and function of the thumb. LEVEL OF EVIDENCE: IV.

ABSTRACT

BACKGROUND: Patients with heart failure often have concomitant renal disease which can result in uremic platelet dysfunction. Determining whether uremia has affected platelets by platelet aggregometry can be challenging in these patients since they are often on antiplatelet medications. This study was undertaken to determine if platelet aggregation studies could identify heart failure patients at risk for uremic bleeding prior to cardiac surgery. METHODS: Platelet aggregation studies from three groups were studied and compared: 17 heart failure patients with mild to moderate renal impairment, 17 heart failure patients without renal abnormalities and 17 healthy volunteers. RESULTS: Platelet aggregation was severely impaired in both heart failure groups with and without renal abnormalities compared to healthy controls, and there were no significant differences in platelet aggregation in response to any of the agonists. There was a pan-decrease in platelet aggregation to all agonists in all heart failure patients. CONCLUSION: Platelet aggregometry does not appear to be useful in measuring platelet dysfunction in heart failure patients with mild to moderate renal impairment.

ABSTRACT

INTRODUCTION: A clinical series of patients was studied to compare the functional score after the use of a single versus two percutaneous iliosacral screws for unstable posterior pelvic ring fractures with or without anterior fixation with the aim to explore if the addition of a second screw would provide better results regarding the functional outcome score. MATERIALS AND METHODS: This case series includes 77 patients with an average of 32.6 years who suffered unstable posterior pelvic ring fractures. Forty-six were Tile type C and 31 were Tile type B. Patients underwent closed reduction and were fixed using percutaneous fluoroscopic-guided iliosacral screws in the supine position with 1 screw in 50 fractures, 2 screws in 37 fractures, 2 fractures were fixed with plates after ORIF, and in 6 cases (out of the bilateral cases) the undisplaced side was unfixed. Postoperatively three patients were lost to follow up and 74 patients (84 posterior fractures fixed with screws) were followed up for a mean of 37.4 months (range 6-151 months) and were evaluated using the Majeed score (1989). RESULTS: Clinical union occurred in all the patients, although in two cases posterior fixation failed and was revised. Radiologically excellent reduction was achieved in 55 patients (71.4%), good in 16 (20.8%), fair in 6 (7.8%) and none had poor reduction. Statistically; among 62 cases that completed the Majeed score evaluation at the last follow-up session, there was no significant difference p value 0.051 between two groups. We also compared Majeed score in Tile B and C fractures fixed with one versus two screws. CONCLUSION: The addition of a second screw for posterior fixation did not show any statistically significant difference regarding functional outcome. LEVEL OF EVIDENCE: Level IV clinical trial.

ABSTRACT

BACKGROUND: We have tested the hypotheses that compared with local white Caucasians, UK-resident patients of Bangladeshi descent develop inflammatory bowel disease (IBD) at a younger age; more often have Crohn's disease than ulcerative colitis (UC); and have a more aggressive disease course. AIM: To test the hypotheses that compared to white Caucasian patients of English, Scottish or Welsh descent, patients of Bangladeshi descent develop IBD at a younger age; more often have Crohn's disease; and have a more aggressive disease course by screening case-records of these patients. METHODS: We screened the case-records of 132 Bangladeshi and 623 white Caucasian consecutive out-patients. We then matched each Bangladeshi to a patient of white Caucasian descent for age at diagnosis and disease duration. Data on migration status, phenotype, disease course, treatments and extra-intestinal manifestations and complications were obtained. RESULTS: No differences were seen in the adjusted age at diagnosis of IBD between Bangladeshi and white Caucasian patients. More Bangladeshis than white Caucasian patients (P < 0.01) were diagnosed with Crohn's disease than UC. Crohn's phenotype at diagnosis was similar in both groups. However, multivariate Cox logistic regression analyses showed that Bangladeshis developed perianal complications (HR [95% confidence interval CI] 8.6 [1.4, 53.1], P = 0.02), and received anti-TNFs (HR [95% CI] 3.0 [1.2, 7.7], P = 0.02) earlier and underwent surgery later (HR [95% CI] 0.4 [0.2, 0.9], P = 0.03) than white Caucasians. More Bangladeshis with UC had extensive disease (24/40 [60%]) than white Caucasians (16/49 [33%], P = 0.02). Overall, more Bangladeshis were anaemic and vitamin D deficient. CONCLUSIONS: Bangladeshi patients with IBD more frequently have Crohn's than UC. Bangladeshis with Crohn's more frequently develop perianal disease, have earlier medication escalation and undergo surgery later than white Caucasians. Bangladeshis have more extensive UC than white Caucasians. The relative contributions of genotype and environmental factors, including vitamin D, to these phenotypic differences require additional study.

ABSTRACT

BACKGROUND: Anxiety and depression are common in patients with inflammatory bowel disease (IBD); however, the factors associated with mood disorders in patients with ulcerative colitis (UC) and Crohn's disease (CD) are poorly defined. METHODS: In all, 103 patients with UC, 101 with CD, and 124 healthy controls completed the Hospital Anxiety and Depression Scale (HADS). Disease activity was defined both from symptom scores and in UC endoscopically, and in CD by fecal calprotectin and/or serum C-reactive protein. Multivariate regression analyses were used to identify factors associated with anxiety and depression. RESULTS: In both UC and CD, anxiety (HADS-A) and depression (HADS-D) scores were higher than in controls (HADS-A: 8.5 ± 4.1 [mean ± SD], 8.6 ± 3.9, 3.2 ± 1.8, P < 0.001; and HADS-D: 4.1 ± 3.3, 4.7 ± 3.3, 1.7 ± 1.4, P < 0.001, respectively). There were no differences in the prevalence of mild, moderate, and severe anxiety and depression in UC and CD. In UC, anxiety scores were associated with perceived stress and a new diagnosis of IBD; depression was associated with stress, inpatient status, and active disease. In CD, anxiety was associated with perceived stress, abdominal pain, and lower socioeconomic status, and depression with perceived stress and increasing age. CONCLUSIONS: Anxiety and depression are common in IBD. Perceived stress is associated with mood disturbances in both UC and CD, but the other associated factors differ in the two diseases. Gastroenterologists should look for mood disorders in IBD and consider stress management and psychotherapy in affected patients.

ABSTRACT

BACKGROUND: Depression, like adverse events and psychological stress, can trigger relapse in inflammatory bowel disease (IBD); however, the effects of psychoactive drugs on disease course are unclear. METHODS: Using retrospective electronic case note review, after exclusion of five patients on low-dose tricyclic antidepressants we compared the course of IBD in 29 patients (14 ulcerative colitis and 15 Crohn's disease), during the years before (year 1) and after (year 2) they were started on an antidepressant for a concomitant mood disorder to that of controls matched for age, sex, disease type, medication at baseline, and relapse rate in year 1. RESULTS: Patients had fewer relapses and courses of steroids in the year after starting an antidepressant than in the year before (1 [0-4] (median [range]) vs. 0 [0-4], P = 0.002; 1 [0-3] vs. 0 [0-4], P < 0.001, respectively); the controls showed no changes between years 1 and 2 in relapses (1 [0-4] vs. 1 [0-3], respectively) or courses of steroids (1 [0-2] vs. 0 [0-3]). Although there were no differences in the use of other relapse-related medications, outpatient attendances, or hospital admissions, the number of endoscopies fell significantly in the antidepressant group in year 2 compared with year 1 (P < 0.01). No such changes were seen in the controls. CONCLUSIONS: Antidepressants, when used to treat concomitant mood disorders in IBD, seem to reduce relapse rates, use of steroids, and endoscopies in the year after their introduction. These results suggest the need for a prospective controlled trial to evaluate their effects on disease course in patients with IBD.

ABSTRACT

BACKGROUND AND OBJECTIVES: Children and adolescents with inflammatory bowel disease (IBD) have more extensive and severe disease than adults. Despite a lack of comparative studies, thiopurines are frequently cited as being more efficacious in children. To test this assertion, we compared the efficacy of thiopurines in children with IBD with that in adults matched for disease phenotype. PATIENTS AND METHODS: Fifty paediatric and adult patients with IBD started on a thiopurine were matched for sex, disease type, and extent. Retrospective data were obtained by electronic case note review, and corticosteroid-free clinical remission and tolerance rates at 6 months as well as relapse rates during the subsequent year were recorded. RESULTS: Adverse effects caused discontinuation of thiopurines in 1 of 50 children and 16% (8/50) of adults (P < 0.05). At 6 months, steroid-free remission was achieved in 30% (15/50) of children and 38% (19/50) of adults (P = 0.53). No differences in remission rates were seen according to disease type. At the end of the following year, 73% (11/15) of children and 68% (13/19) of adults remained in remission (P = 1). CONCLUSIONS: Thiopurines are tolerated better by children. When phenotype is matched, there is no difference in the therapeutic response to thiopurines between children and adults with IBD.

ABSTRACT

This study aimed to ascertain the value of posters at medical meetings to presenters and delegates. The usefulness of posters to presenters at national and international meetings was evaluated by assessing the numbers of delegates visiting them and the reasons why they visited. Memorability of selected posters was assessed and factors influencing their appeal to expert delegates identified. At both the national and international meetings, very few delegates (< 5%) visited posters. Only a minority read them and fewer asked useful questions. Recall of content was so poor that it prevented identification of factors improving their memorability. Factors increasing posters' visual appeal included their scientific content, pictures/graphs and limited use of words. Few delegates visit posters and those doing so recall little of their content. To engage their audience, researchers should design visually appealing posters by presenting high quality data in pictures or graphs without an excess of words.

ABSTRACT

BACKGROUND: Although patients with inflammatory bowel disease (IBD) are at increased risk of osteoporosis, low bone mineral density (BMD) alone confers only a modest increase in risk of fracture. The FRAX score, developed by the WHO, is a free web-based clinical scale assessing the 10-year fracture risk and need for lifestyle advice/reassurance, dual X-ray absorptiometry (DEXA) scanning or preventive treatment. AIM: To assess the accuracy of pre-BMD FRAX scores in identifying at risk IBD patients needing BMD measurement (intermediate risk) and/or therapy (high risk). METHODS: We calculated FRAX scores retrospectively in 116 consecutive IBD out-patients (81 Crohn's disease, 35 ulcerative colitis), who were having DEXA scans in 2005-2009 because they were considered at risk of osteoporosis. RESULTS: On DEXA scans, 47% (38/81) and 12% (10/81) patients with Crohn's disease were osteopaenic and osteoporotic, respectively; equivalent figures for patients with UC were 34% (12/35) and 14% (5/35). The clinical FRAX score alone, when compared with the FRAX score including the BMD result, had a sensitivity of 100% (95% CI: 70-100%), specificity of 40% (95% CI: 31-50%), positive predictive value of 16% (95% CI: 9-27%) and negative predictive value of 100% (95% CI: 90-100%) in identifying those patients needing BMD measurement (intermediate risk) or preventive therapy (high risk). CONCLUSIONS: In patients with IBD perceived to be at risk of osteoporosis and/or osteopaenia, the clinical FRAX score alone can predict accurately the risk of osteoporotic fracture, and thereby reduce the need for DEXA scans and unnecessary anti-osteoporosis treatment.

ABSTRACT

Dietary fat intake is extremely low in most communities with vitamin A deficiency. However, its role in vitamin A status of pregnant and lactating women is poorly understood. The aim of the study was to examine the effect of supplementing women with fat from mid-/late pregnancy until six months postpartum on their vitamin A status and that of their infants. Women recruited at 5-7 months of gestation were supplemented daily with 20 mL of soybean-oil (n = 248) until six months postpartum or received no supplement (n = 251). Dietary fat intake was assessed by 24-hour dietary recall at enrollment and at 1, 3 and 6 months postpartum. Concentrations of maternal plasma retinol, beta-carotene, and lutein were measured at enrollment and at 1, 3 and 6 months postpartum, and those of infants at six months postpartum. Concentration of breastmilk retinol was measured at 1, 3 and 6 months postpartum. The change in concentration of plasma retinol at three months postpartum compared to pregnancy was significantly higher in the supplemented compared to the control women (+0.04 vs -0.07 micromol/L respectively; p < 0.05). Concentrations of plasma beta-carotene and lutein declined in both the groups during the postpartum period but the decline was significantly less in the supplemented than in the control women at one month (beta-carotene -0.07 vs -0.13 micromol/L, p < 0.05); lutein -0.26 vs -0.49 micromol/L, p < 0.05) and three months (beta-carotene -0.04 vs -0.08 micromol/L, p < 0.05; lutein -0.31 vs -0.47 micromol/L, p < 0.05). Concentration of breastmilk retinol was also significantly greater in the supplemented group at three months postpartum than in the controls (0.68 +/- 0.35 vs 0.55 +/- 0.34 micromol/L respectively, p < 0.03). Concentrations of infants' plasma retinol, beta-carotene, and lutein, measured at six months of age, did not differ between the groups. Fat supplementation during pregnancy and lactation in women with a very low intake of dietary fat has beneficial effects on maternal postpartum vitamin A status.

ABSTRACT

Despite the national vitamin A and antihelminthic prophylaxis programmes, both intestinal geohelminths and subclinical vitamin A deficiency continue to be prevalent among children in developing countries. Studies on potential synergistic effects of vitamin A supplementation and deworming on retinol status have inconsistent results. The purpose of the present study was to investigate the impacts of low-dose beta-carotene supplementation and antihelminthic therapy on serum retinol and beta-carotene concentrations in preschool children of Bangladesh. Two hundred and forty-four children, known to be infected with Ascaris lumbricoides, were randomized into four treatment groups: I-IV. Group I and II received two oral doses of 400 mg of albendazole each, the first dose at baseline and the second dose after four months; Group III and IV received placebo in place of albendazole. In addition, Group I and III received 1.2 mg of beta-carotene powder in capsule daily for six months, and Group II and IV received placebo in place of beta-carotene. Serum retinol and beta-carotene levels were measured before and after six months of the interventions. Serum retinol and beta-carotene increased significantly in Group I where both antihelminthic therapy and daily beta-carotene supplementation were given (p<0.05 and p<0.001 respectively). Antihelminthic therapy alone only improved serum beta-carotene concentration (p<0.0001). Low-dose beta-carotene supplementation, along with an antihelminthic therapy, synergistically improved vitamin A status. This finding has public-health implications for improving vitamin A status of children in developing countries.

ABSTRACT

BACKGROUND: Ephrin A4 is one of the ephrin ligand molecules belonging to the tyrosine kinases receptor family. It was originally identified in a T-lymphoma cell line and seen to be expressed in human adult tissue as well as several tumor types. In our previous study, we showed the unique pattern of ephrin A4 immunohistochemical staining, which differed according to the type of examined bone specimens (normal bone, primary, and metastatic osteosarcoma lesions). The aim of the present study is to evaluate the prognostic impact of ephrin A4 expression in a group of primary osteosarcoma patients. MATERIALS AND METHODS: Ephrin A4 immunohistochemical expression was carried out on 47 primary osteosarcoma cases. RESULTS: Ephrin A4 was expressed in 82.9% of osteosarcoma cases with cytoplasmic localization in 58.9% of positive cases. The cytoplasmic pattern was significantly associated with aggressive histopathological types of osteosarcoma (P = 0.02), advanced stage (P = 0.04), the presence of metastasis (P = 0.03), inferior response to neoadjuvent chemotherapy (P = 0.04), and tended to be associated with a shorter event-free survival (P = 0.09). CONCLUSIONS: The cytoplasmic pattern of ephrin A4 could identify a subgroup of primary osteosarcoma patients with a high liability for progression, poor prognosis, and inferior response to chemotherapy.

ABSTRACT

Arsenic contamination of tubewell water is a major public-health problem in Bangladesh. In the recent years, the use of shallow and deep tubewell water for irrigation and the use of excess amount of cheap fertilizers and pesticides containing cadmium pose a serious threat of contamination of arsenic and cadmium in food. In an exploratory study, arsenic and cadmium were measured in foods from Matlab, a rural area in Bangladesh, that is extensively affected by arsenic and the economy is agriculture-based. Raw and cooked food samples were collected from village homes (households, n=13) and analyzed to quantify concentrations of arsenic and cadmium using atomic absorption spectrophotometry. Washing rice with water before cooking reduced the concentration of arsenic in raw rice by 13-15%. Rice, when cooked with excess water discarded, showed a significant decrease in arsenic concentration compared to that cooked without discarding the water (p<0.001). In contrast, concentration of cadmium did not decrease in cooked rice after discarding water. Cooked rice with discarded water had significantly lower concentration of arsenic compared to raw rice (p=0.002). Raw rice had higher concentration of arsenic compared to raw vegetables (p<0.001); however, no such difference was found for cadmium. Compared to raw vegetables (e.g. arum), concentration of arsenic increased significantly (p=0.024) when cooked with arsenic-contaminated water. Thus, the practice of discarding excess water while cooking rice reduces the concentration of arsenic but not of cadmium in cooked rice. However, water generally not discarded when cooking vegetables to avoid loss of micronutrients consequently retains arsenic. The results suggest that arsenic and cadmium have entered the food-chain of Bangladesh, and the cooking practices influence the concentration of arsenic but not of cadmium in cooked food.

ABSTRACT

BACKGROUND/OBJECTIVES: Many children have diets deficient in both iron and zinc, but there has been some evidence of negative interactions when they are supplemented together. The optimal delivery approach would maximize clinical benefits of both nutrients. We studied the effectiveness of different iron and zinc supplement delivery approaches to improve diarrhea and anemia in a rural Bangladesh population. STUDY DESIGN: Randomized, double blind, placebo-controlled factorial community trial. RESULTS: Iron supplementation alone increased diarrhea, but adding zinc, separately or together, attenuated these harmful effects. Combined zinc and iron was as effective as iron alone for iron outcomes. All supplements were vomited <1% of the time, but combined iron and zinc were vomited significantly more than any of the other supplements. Children receiving zinc and iron (together or separately) had fewer hospitalizations. Separating delivery of iron and zinc may have some additional benefit in stunted children. CONCLUSIONS: Separate and combined administration of iron and zinc are equally effective for reducing diarrhea, hospitalizations and improving iron outcomes. There may be some benefit in separate administration in stunted children.

ABSTRACT

BACKGROUND: The incidence of inflammatory bowel disease (IBD) is increasing among adolescents. In all, 25% of patients are diagnosed before the age of 16, when they are traditionally transferred from the pediatric to the adult service. METHODS: We conducted a retrospective case-controlled study to characterize patients treated in a novel transitional adolescent-young adult IBD clinic. This compared disease extent, radiation exposure, therapeutic strategy, and requirement for surgery in 100 adolescents with controls from our adult IBD clinic matched for disease duration. RESULTS: The median (range) ages for the adolescent and adult population was 19 (16-28) and 43 (24-84), with a median age at diagnosis of 15 (3-26) and 39 (13-82) respectively (P < 0.001). Crohn's disease was significantly more common in the adolescents. Disease distribution was ileocolonic in 69% of adolescents and 28% of adults, restricted to the ileum in 20% of adolescents and 47% of adults, and colonic only in 11% and 22%, respectively. Upper gastrointestinal involvement occurred in 23% of adolescents, but was not seen in adults (P < 0.01). Total ulcerative colitis was seen in 67% of adolescents and 44% of adults (P < 0.01). Contrary to previous data adolescents did not receive more ionizing radiation than adults. Requirement for immunosuppressive therapy was higher in the adolescent group (53% versus 31%, respectively, P < 0.01). Likewise, 20% of adolescents had required biological therapy compared to only 8% in the adult cohort (P < 0.05). CONCLUSIONS: Gastroenterologists should recognize that IBD is more complex when presenting in adolescence and our data support the creation of specific adolescent transitional clinics.

ABSTRACT

BACKGROUND: Despite the wide use of azathioprine/mercaptopurine (AZA/MP) therapy in the management of both Crohn's disease (CD) and ulcerative colitis (UC), approximately 20% of patients cannot tolerate the drugs and 30% do not respond. AIM: To examine the efficacy and safety profile of methotrexate (MTX) in patients with CD or UC who are either intolerant or non-responsive to AZA/MP. METHODS: A total of 131 patients with IBD treated with MTX were identified. Retrospective data were obtained by case note review. Clinical response (defined as steroid withdrawal, normalization of previously raised CRP or physician's clinical assessment of improvement) was assessed at 6 months. RESULTS: Clinical response in Crohn's disease occurred in 18 of 29 patients (62%) refractory to AZA/MP and 42 of 70 patients (60%) intolerant to AZA/MP, with no difference between the groups (P = 1.0). In UC, clinical response was seen in 7 of 9 (78%) patients refractory to AZA/MP and 15 of 23 (65%) intolerant to thiopurines. MTX was well tolerated in a majority of individuals. CONCLUSIONS: Methotrexate appears effective in both CD and UC patients who fail to respond to or are intolerant to AZA/MP therapy.

ABSTRACT

Previous studies showed better absorption of protein and catch-up growth with animal-based high protein (15% energy from protein) diets (AP) than plant-based diets. This study compared the intake and absorption of nutrients from a lentil-based high protein (15% energy from protein) diet (LenP), AP, and a low protein (7.5% energy from protein) diet (LP). A total of 31 moderately malnourished 24 to 59 month old children convalescing from shigellosis were randomised to these three diets: LenP (n=11), AP (n=9) and LP (n=11). After two weeks adaptation with the respective diets, a 72-hour metabolic balance study was performed. The children's baseline characteristics were comparable among the groups (one exception: children of LP group were less stunted). The costs of 1,000 kcal from LenP, AP and LP diets were 0.15, 0.75 and 0.11 US dollar, respectively. Average daily energy intake (115-119 kcal/kg/d), coefficients of carbohydrate (89-91%), fat (80-90%), and energy (87-89%) absorption were similar in all groups. Mean+/-SD coefficient of nitrogen absorption (%) and nitrogen balance (g/kg/day) were 81+/-6 and 0.35+/-0.21 in LenP, 82+/-5 and 0.36+/-0.08 in AP, and 73+/-4 and 0.13+/-0.06 in LP groups, respectively (for both the nitrogen absorption and balance comparisons: LenP vs. AP, p>0.05; LenP vs. LP, p<0.05; AP vs. LP, p<0.05). The results showed higher absorption of nitrogen and its balance from high protein diets whether derived from lentil or animal source, which may enhance tissue protein deposition. A lentil-based high protein diet, which is less expensive, may be useful for nutritional rehabilitation of moderately malnourished children.
