Development and reproducibility of a tool to assess school food-purchasing practices and lifestyle habits of Australian primary school-aged children

Objective: To describe the development and reproducibility of a self‐report instrument, for use with children in years 4–6, to identify sources of food eaten during the day, and type and frequency of food purchases at school. Design: Tool development stages included formulation of content and format, expert review, piloting and a test–retest study. Subjects/setting: The pilot study included school students (n = 20) in years 4 and 5 (seven girls, mean age 9.7 ± 0.7 years) attending an Australian public primary school. The test–retest study was performed in a large metropolitan public primary school (n = 245 children, 52% female, mean age 10.7 ± 0.91 years) including children from years 4 (n = 88), 5 (n = 84) and 6 (n = 73). Statistical analysis: A Kappa statistic was used to assess level of agreement between the two time periods separated by 1 week. The results were analysed using SAS version 8.2 with each question compared at time 1 and 2. Results: The mean kappa was 0.529 using pairings from 17 questions. Values ranged from 0.18 to 0.71 (CI 0.46–0.60). Conclusions and applications: The School Eating Habits and Lifestyle Survey has been developed and pilot‐tested in primary school‐aged children and shown to have moderate stability over time. The results show that each phase of development, particularly those spent in consultation and testing, led to progressive improvement of this instrument. This process improved the quality of information produced and gave insights to self‐report of dietary intake and behaviours among children.     

Socioeconomic status and maternal cigarette smoking before, during and after a pregnancy

Abstract: Research suggests that cigarette use declines when women find out they are pregnant, increasing again after the birth. Pregnancy may provide many women with a substantial impetus to stopping smoking. Also, rates of smoking cessation and reduction may be class-related, with the highest socioeconomic-status groups manifesting higher rates of reduction. Using data from the Mater Hospital-University of Queensland Study of Pregnancy, we report family income related to rates of smoking before, during and after a pregnancy. Before becoming pregnant, 45.9 per cent of women in the sample were smokers. This declined to 34.7 per cent of women at their first clinic visit. Rates of heavy smoking (20 or more cigarettes per day) had returned to earlier levels by the six-month (after birth) follow-up. Women in the lowest family-income group had the highest rates of cigarette use before, during and after their pregnancy. Of the lowest family-income group, 8.4 per cent were heavy smokers before, during and after their pregnancy, compared with 2.8 per cent of women in the highest family-income group. Smoking cessation rates were highest in the highest family-income group (those who smoked least), but relapse rates after the birth were similar for all income groups. Arresting rates of smoking relapse by pregnant women should be seen as a major public health priority     

Studies of fish consumption as source of methylmercury should consider fish-meal-fed farmed fish and other animal foods

The co-occurrence of fish MeHg and omega-3 fatty acids in wild species can indeed be optimized by choosing certain species. Farmed finfish and shellfish that are fed fish-meal, however, can bioconcentrate both MeHg (in muscle) and organohalogen pollutants passed on in the fat components [Dorea, J.G., 2006. Fish meal in animal feed and human exposure to persistent bioaccumulative and toxic substances. J. Food Prot. 69, 2777-2785); when fish-meal is used to feed farm animals it may offer the worst of both worlds: saturated fat (with organohalogen pollutants) and MeHg. It is time to address the dietary sources of Hg derived from animals raised on fish-meal that may contribute to increase tissue Hg concentrations.     

Accidental hypothermia in a child

We report a case of severe accidental hypothermia (24.8 degrees C) in a seven-year-old child due to prolonged exposure to low temperatures and temporary contact with river water. When the patient was seen in hospital, bradycardia (30.min-1), bradypnoea (5. min-1), scarcely reacting pupils, and Glasgow Coma Scale=3 were noted. For rewarming minimally invasive techniques (humidified warmed gases and intravenous solutions at 40 degrees C) were employed with a very successful outcome.     

Dramatic Response of Scarring Scalp Discoid Lupus Erythematosus (DLE) to Intravenous Methylprednisolone, Oral Corticosteroids, and Hydroxychloroquine in a 5-Year-Old Child

Abstract:  Discoid lupus erythematosus (DLE) is rare in childhood. We report the case of a 5-year-old girl who presented with erythematous scaly plaques, with scarring alopecia, involving approximately 40% of her scalp. Histopathology confirmed the diagnosis of DLE. Treatment with intravenous methylprednisolone, hydroxychloroquine, oral prednisone, topical corticosteroids, and sunscreen lead to reversal of scarring alopecia and re-growth of hair.     

Histiocytic erythema multiforme

Erythema multiforme is histologically characterized by liquefactive degeneration along the dermal-epidermal junction, necrotic keratinocytes and a lymphocytic infiltrate. We report a 10-year-old boy with recurrent erythema multiforme major of undetermined etiology with unusual histologic findings. A skin biopsy taken at day 2 of his eruption revealed histologic features otherwise characteristic of erythema multiforme, but mediated instead by a CD68-positive infiltrate, resembling cutaneous Kikuchi's disease. To the best of our knowledge this is the first reported case of 'histiocytic' erythema multiforme.     

The role of growth factor administration and T-cell recovery after peripheral blood progenitor cell transplantation in the treatment of solid tumors: results from a randomized comparison of G–CSF and GM–CSF

BACKGROUND: Peripheral blood progenitor cell (PBPC) transplantation (PBPCT) combined with post-PBPCT administration of myelopoietic growth factors is a valid therapeutic intervention to rapidly restore hematopoiesis after the delivery of intensive, myeloablative cancer chemotherapy. On the other hand, the best growth factor regimen to potentiate PBPC-mediated immunohematopoietic recovery has yet to be determined. STUDY DESIGN AND METHODS: In a randomized evaluation, the effects produced by post-PBPCT G-CSF and GM-CSF on myeloid/lymphoid recovery and transplant outcome in women with chemosensitive cancer were compared. Thirty-seven ovarian cancer patients and 34 breast cancer patients ranging in age from 24 to 60 years were treated with carboplatin, etoposide, and melphalan (CEM) high-dose chemotherapy and then randomly assigned to receive G-CSF (5 microg/kg subcutaneously) or GM-CSF (5 microg/kg subcutaneously) until Day 13 after PBPCT. Patients were compared in regard to hematopoietic recovery, posttransplant clinical management, and immune recovery. Finally, clinical outcome was estimated as time to progression and overall survival. RESULTS: Hematopoietic recovery and posttransplant clinical management were comparable in both the G-CSF and GM-CSF series. Conversely, significantly higher T-cell counts were observed in G-CSF-treated patients during the early and late posttransplant follow-up. Patients who received G-CSF showed a significantly longer median time to progression. A parallel analysis revealed that patients in whom a higher CD3+ count was recovered had a significantly longer overall survival and time to progression. CONCLUSION: The enhancement of post-PBPCT T-cell recovery observed in G-CSF-treated patients encourages the use of G-CSF to ameliorate immune recovery, which seems to play a role in post-PBPCT control of disease in cancer patients. GM-CSF might be administered to prolong immunosuppression after autologous PBPCT for autoimmune diseases or allogeneic PBPCT.
