Validity of exploration for suitable vessels for replantation in the distal fingertip amputation in early childhood: Replantation or composite graft

Abstract Composite grafting, grafting without microvascular anastomoses, has been widely performed for distal fingertip amputation in children with variable results, whereas successful replantation of these amputations using microsurgical technique has been reported. However, most of these reports included a wide age-range and a mix of different amputation levels. This study reviewed our cases of paediatric digital amputation, in order to verify the value of distal fingertip replantation over composite grafting, especially in early childhood. Seventeen young children (aged 3 years and 8 months on average), with single-digit fingertip amputations in Tamai zone I were reviewed from 1993–2008. Each amputation was subdivided into three types: distal, middle, and proximal. There were three distal, 13 middle, and one proximal type zone I amputations. All were crush or avulsion injuries. All three distal-type cases were reattached as primary composite grafts with one success. For middle-type cases, the survival rate of primary composite graft without exploration for possible vessels for anastomosis was 57%. On exploration, suitable vessels for anastomosis were found 50% of the time, in which all replantations were succeeded. The remaining cases were reattached as secondary composite grafts, with one success using the pocket method. Consequently, the success rate after exploration was 67%. The only one proximal-type amputation was failed in replantation. For the middle-type zone I amputation in early childhood, replantation has a high success rate if suitable vessels can be found. Therefore, exploration is recommended for amputations at this level with a view to replantation, irrespective of the mechanism of injury.
A Family-based Randomized Controlled Trial of Pain Intervention for Adolescents With Sickle Cell Disease

The study had 2 aims---to determine the efficacy of a family-based cognitive-behavioral pain management intervention for adolescents with sickle cell disease (SCD) in (1) reducing pain and improving health-related variables and (2) improving psychosocial outcomes. Each adolescent and a family support person were randomly assigned to receive a brief pain intervention (PAIN) (n=27) or a disease education attention control intervention (DISEASE ED) (n=26) delivered at home. Assessment of primary pain and health-related variables (health service use, pain coping, pain-related hindrance of goals) and secondary psychosocial outcomes (disease knowledge, disease self-efficacy, and family communication) occurred at baseline (before randomization), postintervention, and 1-year follow-up. Change on outcomes did not differ significantly by group at either time point. When groups were combined in exploratory analyses, there was evidence of small to medium effects of intervention on health-related and psychosocial variables. Efforts to address barriers to participation and improve feasibility of psychosocial interventions for pediatric SCD are critical to advancing development of effective treatments for pain. Sample size was insufficient to adequately test efficacy, and analyses did not support this focused cognitive-behavioral pain management intervention in this sample of adolescents with SCD. Exploratory analyses suggest that comprehensive interventions, that address a broad range of skills related to disease management and adolescent health concerns, may be more effective in supporting teens during healthcare transition.
Association of age specific body mass index, dental caries and socioeconomic status of children and adolescents.

AIMS AND OBJECTIVES The purpose of this study was to determine the association of BMI-for-age with dental caries and socioeconomic status. METHOD A random sample of 2033 school going children aged 6-15 years were selected from ten different schools located in the south of Bangalore city. Height and weight of each child was recorded to obtain BMI-for-age. The socioeconomic status (SES) was assessed based on educational status, profession and annual income of parents. Dental caries was recorded according to WHO criteria. A diet recording sheet was given to each child to record his/her dietary intake of the four basic food groups and snacks for 5 consecutive days including one weekend day. The data obtained was subjected to statistical analysis. RESULTS The results showed that a higher number of children who were overweight and at a risk of overweight were seen in the upper SES and both showed a higher mean dietary intake of all the four food groups and snacks. The mean deft score was significantly higher in underweight children. A significantly higher mean DMFT score was observed in children at risk of overweight and overweight children. CONCLUSIONS Children from the upper classes consumed more food, including snacks and were either at a risk of overweight or overweight. They had more caries in their permanent dentition. Underweight children were seen in the lower class. Although their intake of snacks was less, they had higher caries in their primary dentition.
Methods for Identification of Staphylococcus aureus Isolates in Cases of Bovine Mastitis

ABSTRACT A total of 272 staphylococcal isolates from cases of bovine mastitis (159 Staphylococcus aureus) belonging to 12 different species were identified with ID32 STAPH galleries, and 51 of them were confirmed by 16S rRNA gene (rrs) sequencing. The same isolates were examined for their hemolytic activity on sheep blood agar, DNase activity, and coagulase activity and with two rapid identification kits (Slidex Staph Plus kit and RAPIDEC Staph from Bio-Merieux). The results of this study confirm those obtained by other groups with hemolysis, DNase, and coagulase. Only 50% of S. aureus isolates from mastitis cases show coagulase activity after 4 h of incubation, and a 24-h incubation is necessary for the full sensitivity of this test. In contrast to results from other studies with human isolates, the Slidex Staph Plus kit was not sensitive enough for the identification of S. aureus from bovine mastitis samples. The aurease test of the RAPIDEC Staph kit showed 100% sensitivity and 100% specificity. Used in conjunction with hemolysis patterns, the RAPIDEC Staph kit is therefore very well adapted to rapid, efficient, and cost-effective identification of S. aureus in cultures from bovine mastitis samples. Sequencing of rrs genes also proved very efficient in identifying the Staphylococcus species encountered in these samples and confirming phenotypical identification results with unsatisfactory scores. With continuously improving technologies and decreasing costs, genetic identification methods like rrs gene sequencing will soon find a place in routine veterinary diagnostics.
Agglomeration and Clusters: Tools and Insights from Coagglomeration Patterns

Geographic clusters have received first-order policy attention despite our limited academic knowledge about them. I explain how coagglomeration patterns of industries can inform the analysis of clusters by allowing us to better delineate them; to explore the causal mechanisms underlying them; and to more finely assess their impact on various economic outcomes.
Descriptive analysis of eating behavior in school-age children with cystic fibrosis and healthy control children.

STUDY OBJECTIVE To investigate calorie intake, behavioral eating styles, and parent perception of eating behavior of school-age children with cystic fibrosis (CF) compared with healthy peers. DESIGN A two-group comparison study. SETTING A clinical sample of 28 school-age children with CF and a community sample of 28 healthy peers matched for age (6 to 12 years) and socioeconomic status. MEASUREMENTS AND MAIN RESULTS The children with CF consumed more calories per day (2175 cal/d) than the control children (1875 cal/d) and achieved a significantly higher recommended daily allowance (RDA) of energy (128% of the RDA) than the control children (91.61% of the RDA). Fifty-four percent of the CF sample were achieving the CF dietary recommendations of 120% of the RDA. Despite this energy intake, the CF sample was significantly below the control sample on weight (24.56 vs 31.23 kg), height (125.48 vs 133.06 cm), and z score for weight (-0.811 vs 0.528) and height (-0.797 vs 0.371). On measures of behavioral eating style, the CF sample had significantly longer meals (23.90 min) than the control sample (17.34 min) and had a significantly slower pace of eating (43.27% 10-second intervals with bites) than the control sample (51.29% 10-second intervals with bites) but did not differ significantly on the number of calories consumed during dinner. On a measure of parent report of mealtime behaviors, parents of the children with CF rated mealtime behavior problems of "dawdles" and "refuses food" as more intense (mean, 3. 46) than did the parents of control children (mean, 2.67). For the CF sample, a significant correlation was found between the parent intensity ratings of problem behavior in general and meal duration (r = .48), and a significant negative correlation was found between the parent intensity ratings of problem mealtime behaviors and the percentage of intervals with bites (pace of meal) (r = -.533). CONCLUSIONS Although the school-age children with CF were consuming more calories per day than their healthy peers, and more than 50% of the children in the CF sample were at or above the CF dietary recommendations, the children in the CF sample were significantly below the control children on measures of weight and height. The behavioral data suggest that increased caloric intake is not without cost, because the CF sample spent an additional 7 minutes per day at dinner and ate their meals at a slower pace than their healthy peers. These data were associated with higher intensity ratings of mealtime behaviors by parents of children with CF. These findings point to the need for individualized assessment of energy needs for school-age children with CF and comprehensive programs that teach parents behavioral strategies to motivate their children to meet these higher energy requirements in an adaptive manner.
Treatment Modalities for T1N0 Esophageal Cancers: A Comparative Analysis of Local Therapy Versus Surgical Resection

Background: To investigate the role of nonsurgical treatment for early-stage esophageal cancer, we compared the outcomes of local therapy to esophagectomy, using a large, national database. Methods: Five-year cancer-specific and overall survival (OS) of patients, with T1N0M0 squamous cell or adenocarcinoma of the mid or distal esophagus treated with either surgery or local therapy, with ablative and/or excision techniques, in the Surveillance Epidemiology and End Results cancer registry from 1998 to 2008, were compared using the Kaplan–Meier approach, and multivariable and propensity-score adjusted Cox proportional hazard, and competing risk models. Results: Of 1458 patients with T1N0 esophageal cancer, 1204 (83%) had surgery and 254 (17%) had local therapy only. The use of local therapy increased significantly from 8.1% in 1998 to 24.1% in 2008 (p < 0.001). The 5-year OS after local excisional therapy and surgery was not significantly different (55.5% versus 64.1% respectively, p = 0.07), and 5-year cancer-specific survival (CSS) also did not differ (81.7% versus 75.8%, p = 0.10). However, after propensity-score adjustment, CSS was better for patients who underwent local therapy compared with those who underwent surgery (hazard ratio: 0.46, 95% confidence interval: 0.27–0.77, p = 0.003), whereas OS remained similar. Conclusion: The use of local therapy for T1N0 esophageal cancers increased significantly from 1998 to 2008. Compared with those treated with esophagectomy, patients treated with local therapy had similar OS but improved CSS, indicating a higher chance of dying from other causes. Further studies are needed to confirm the oncologic efficacy of local therapy when used in patients whose lifespans are not limited by conditions other than esophageal cancer.
Morphometric analysis of basal cell layer in oral premalignant white lesions and squamous cell carcinoma.

The size and shape of the cells in the basal cell layer of the oral epithelium in 100 specimens from oral mucosa were studied by using an interactive image analysis system (IBAS-1). Four groups of white lesions (traumatic keratosis, lichen planus, leucoplakia, and a "risk group") in addition to two control groups (normal mucosa and squamous cell carcinoma) were studied retrospectively. The results showed a progressive increase in the dimensions (area, perimeter, and maximum diameter) of the nuclei from normal mucosa through traumatic keratosis, lichen planus, leucoplakia and the "risk group" to carcinoma, with considerable differences. The nucleus in squamous cell carcinoma was twice as large as in normal mucosa. A substantial increase in the dimensions of both the cell and the nucleus was found in the "risk group. " The nucleo:cytoplasmic ratio, contrary to what might have been anticipated in risk lesions, did not show considerable differences between the diagnostic groups. Furthermore, it was slightly decreased in the risk group compared with the normal mucosa. The shape factors (form PE and contour index) seemed to be less helpful in the identification of the "risk group. " The size of the basal cell and its nucleus can be of diagnostic value for lesions with a high risk of malignant transformation.
Outcome and risk factors for mortality in children with acute renal failure.

BACKGROUND Acute renal failure (ARF) is an important cause of morbidity and mortality in children. Here, we investigate etiology, comorbidities, outcome and risk factors associated with mortality in these children with ARF. METHODS We retrospectively reviewed the characteristics of 58 children with ARF diagnosed between January 1997 and December 2006 at a single institute. Factors including age, sex, clinical features and laboratory parameters were compared between survivors and non-survivors. RESULTS ARF was secondary to extrarenal causes in 79.3% of cases. Sepsis (18.9%), hematooncologic disease (18.9%) and cardiovascular disease (18.9%), were the main causes of ARF. Primary renal disease due to acute glomerulonephritis, nephrotic syndrome, hemolytic uremic syndrome and obstructive uropathy accounted for 20.7% of the cases. The overall mortality rate was 51.7%. There were no significant differences between survivors and non-survivors in gender and changes in the peak levels of calcium, phosphorous and uric acid levels. The mortality rate was significantly higher when ARF occurred in younger children (p = 0.019), secondary to systemic disease (p = 0.038, odds ratio 4.3; 95% confidence interval (CI) 1.0, 17.9), sepsis (p < 0.001, odds ratio 19.7; 95% CI 5.1, 76.4), use of ventilator (p < 0.001, odds ratio 35; 95% CI 6.7, 182.7), multiple organ failure (p < 0.001) and non-use of renal replacement therapy (p = 0.018, odds ratio, 3.6; 95% CI interval 1.2, 10.6) on univariate analysis. Multiple logistic regression analysis revealed that sepsis (p = 0.011, odds ratio, 11.3; 95% CI 1.7, 73.0) and numbers of organ failures (p = 0.001, odds ratio 8.14; 95% CI 2.5, 26.7) were independently associated with mortality. CONCLUSION This study found that sepsis and number of organ failures were independent predictors of mortality in children with ARF.
3-[3-Methyl-4-(4-nitrobenzylideneamino)-5-sulfanylidene-4,5-dihydro-1H-1,2,4-triazol-1-yl]-1,3-diphenylpropan-1-one dichloromethane monosolvate

In the title compound, C25H21N5O3S·CH2Cl2, the dichloromethane solvent molecule is disordered over four positions, with an occupancy ratio of 0.271 (3):0.3884 (18):0.298 (2):0.0424 (15). The 1,2,4-triazole ring makes dihedral angles of 47.3 (2)/87.3 (2) and 3.6 (2)° with the phenyl and nitrophenyl rings, respectively. An intramolecular C—H⋯S hydrogen bond results in the formation of an almost planar six-membered ring [r.m.s. derivation = 0.0051 (2) Å]. Intermolecular C—H⋯O hydrogen bonding consolidates the structure.
Demand for Residential Mortgage in Ghana: Nature, Constraints and Implications

The benefits of having a vibrant and efficient mortgage market in Ghana cannot be overemphasised as the mortgage market is inextricably linked to overall economic development. Yet, several factors militate against the smooth development of the mortgage market in developing countries. This paper examines the factors hindering the development of the Ghana’s mortgage market from the demand side. It specifically investigates the key variables that affect residential mortgage demand and other constraints to the use of mortgage by households. This objective was achieved by examining the mortgage products available in Ghana and analysing same with survey responses obtained by means of questionnaires administered to 120 public and private sectors workers within the Kumasi Metropolis. A probit regression model was also used to examine the determinants of individuals’ decisions to use mortgage or resort to some other form of housing finance such as incremental housing. The paper reveals that effective demand for residential mortgage in Ghana is constrained by a myriad of factors including low income levels, informal sources of income, high deposit requirements, extortionate interest rate on mortgages resulting in high repayment to income ratios, high and escalating house prices and some negative cultural perceptions. The high interest rates, low income levels and high house prices result high and unreasonable mortgage repayment-to-income ratios. The cumulative effect of these is that low- and middle-income households are priced out of the mortgage market making incremental building their only alternative.

Academic and Behavioral Outcomes in School-Age South African Children Following Severe Traumatic Brain Injury

Background: Children who have sustained severe traumatic brain injuries (TBIs) demonstrate a range of post-injury neurocognitive and behavioral sequelae, which may have adverse effects on their academic and behavioral outcomes and interfere with school re-entry, educational progress, and quality of life. These post-TBI sequelae are exacerbated within the context of a resource-poor country like South Africa (SA) where the education system is in a somewhat precarious state especially for those from disadvantaged backgrounds. Objectives: To describe behavioral and academic outcomes of a group of school-aged SA children following severe TBI. Methods: The sample included 27 school-age children who were admitted to the Red Cross War Memorial Children's Hospital (RXH), SA, between 2006 and 2011 for closed severe TBI and who received intracranial monitoring. We collected behavioral data using the Child Behavior Checklist (CBCL) and the Behavior Rating Inventory of Executive Function (BRIEF) and academic information sourced from the BRIEF, CBCL, medical folders, and caregivers. Analyses include descriptive statistics and bivariate correlation matrices. Results: The descriptive results show that (1) more than half of the participants experienced clinically-significant behavioral problems across the CBCL scales, (2) the working memory BRIEF subscale appeared to be the most problematic subdomain, (3) two thirds of the sample were receiving some form of, or were in the process of being placed in, special needs education, (4) there was a three-fold increase in the use of special education services from pre- to post-injury, and (5) more than half (n = 16) of the sample repeated at least one grade after returning to school post-injury. Correlation analyses results suggest that children with increased externalizing behavioral problems and executive dysfunction are more likely to repeat a grade post-injury; and that children with executive dysfunction post-TBI are more likely to require some form of special educational services. Conclusion: While there is a vast amount of literature on pediatric TBI (pTBI) academic and behavioral outcomes, little literature exists on the pTBI population from the developing world and SA specifically. This is important to address given unique challenges that face the country and its educational system, and its implications for the management and care of children post-TBI.
The effect of experimental cartilage damage and impairment and restoration of synovial lubrication on friction in the temporomandibular joint.

AIMS To evaluate how the frictional coefficient of the porcine temporomandibular joint (TMJ) is affected by an impairment of the synovial lubrication produced by an experimental abrasion of the articular cartilage and the application of hyaluronic acid (HA) with different molecular weights to the abraded cartilage surfaces. METHODS Erosion of the articular cartilage was produced by scouring it with sandpaper. Impairment and restoration of synovial lubrication were modeled by washing the joint space with phosphate-buffered saline (PBS) and by the application of HA with different molecular weights. After measuring the frictional coefficients in the intact TMJs (n = 10), the effects of washing with PBS, sandpaper scouring, and the application of HA were subsequently examined. RESULTS The mean frictional coefficient in the intact joint was 0.0154 (SD 0.0043). After PBS washing and sandpaper scouring, it increased significantly to 0.0235 (SD 0.0052) and 0.0520 (SD 0.0088), respectively. Subsequent application of HA resulted in a significant decrease (43% to 56%) of the frictional coefficient. Observations by scanning electron microscopy showed that after sandpaper scouring, the superficial cartilage layer was disrupted and inner layer was exposed, creating an irregular surface. CONCLUSION Joint friction may increase by approximately 350% following an experimental scouring of the cartilage surface and impairment of synovial lubrication. Lubrication by means of HA decreased joint friction by approximately 50%.
Relation between higher physical activity and public transit use.

OBJECTIVES We isolated physical activity attributable to transit use to examine issues of substitution between types of physical activity and potential confounding of transit-related walking with other walking. METHODS Physical activity and transit use data were collected in 2008 to 2009 from 693 Travel Assessment and Community study participants from King County, Washington, equipped with an accelerometer, a portable Global Positioning System, and a 7-day travel log. Physical activity was classified into transit- and non-transit-related walking and nonwalking time. Analyses compared physical activity by type between transit users and nonusers, between less and more frequent transit users, and between transit and nontransit days for transit users. RESULTS Transit users had more daily overall physical activity and more total walking than did nontransit users but did not differ on either non-transit-related walking or nonwalking physical activity. Most frequent transit users had more walking time than least frequent transit users. Higher physical activity levels for transit users were observed only on transit days, with 14.6 minutes (12.4 minutes when adjusted for demographics) of daily physical activity directly linked with transit use. CONCLUSIONS Because transit use was directly related to higher physical activity, future research should examine whether substantive increases in transit access and use lead to more physical activity and related health improvements.
