Exploring parental perspectives after commencement of flash glucose monitoring for type 1 diabetes in adolescents and young adults not meeting glycaemic targets: a qualitative study.

AIMS: To explore parental perspectives after flash glucose monitoring commencement in adolescents and young adults with type 1 diabetes who were not meeting glycaemic targets. METHODS: Twelve semi-structured interviews were conducted among parents of adolescents and young adults between the ages of 14 and 20 years (inclusive) with type 1 diabetes and not meeting glycaemic targets [HbA1c 81-130 mmol/mol (9.6-14.0%)] participating in a randomized controlled trial. Interviews were transcribed, then thematic analysis was performed to identify themes regarding parental experiences. RESULTS: Four key themes were found: flash glucose monitoring improved parental emotional well-being; flash glucose monitoring reduced diabetes-specific conflict within families; flash glucose monitoring facilitated the parental role in diabetes management; and sensor-related challenges, particularly sensors falling off, interfered with using flash glucose monitoring for diabetes management. The cost of self-funded sensors was the only barrier to continuing flash glucose monitoring that parents reported. CONCLUSIONS: This study provides new insights into the potential benefits and challenges of flash glucose monitoring use, drawn from the perspective of parents of adolescents and young adults not meeting glycaemic targets. As parents are often key partners in obtaining or purchasing this technology, these findings can be used to further inform parental expectations of this technology.

Addison's disease presenting with an acute abdomen and complicated by cardiomyopathy.

Adrenal insufficiency typically presents with non-specific symptoms, followed by shock secondary to a salt-wasting crisis and/or the vascular effects of glucocorticoid deficiency if it progresses to acute adrenal insufficiency. Rhabdomyolysis and cardiac dysfunction are rarely reported, particularly in children. We report a child with adrenal insufficiency, presenting with acute abdominal signs, probably secondary to rhabdomyolysis, and complicated by reversible cardiomyopathy. Acute adrenal insufficiency should be considered with this presentation. The possibility of impaired cardiac function during its treatment should also be considered.

Improved folate status in children and adolescents during voluntary fortification of food with folate.

OBJECTIVE: To assess longitudinal changes in folate status in South Australian children and adolescents during fortification of food with folic acid. METHODS: Sixty-nine children and adolescents (age 12.8 +/- 2.3 years), 47 with diabetes and 22 healthy controls, had their folate status assessed at the beginning of 1999 and again after a mean 1.1 +/- 0.23 years. Intake of folate at baseline was assessed with a quantitative food frequency questionnaire. RESULTS: Baseline red cell folate (mean +/- standard deviation (SD)) was 756 +/- 294.5 nmol/L and remained constant at follow up at 736 +/- 299 nmol/L (P = 0.55) in the whole group. Serum folate increased from 24.4 +/- 6.3 nmol/L to 27.2 +/- 8.8 nmol/L (P = 0.002). Children with diabetes showed a significant increase in serum folate (from 26.3 +/- 5.7-30.1 +/- 7.9, P < 0.001) and stable red cell folate (835.8 +/- 278.6 and 808.6 +/- 296.7, P = 0.51) between baseline and the second samples, while controls showed stable serum (20.4 +/- 5.7 and 21.1 +/- 7.7, P = 0.7) and red cell folate (586.6 +/- 255.9 and 579.8 +/- 240.1, P = 0.92). A third sample collected in 17 subjects after a further 9 +/- 1.3 months showed a further increase in serum and red cell folate. Mean folate intake at baseline was 301 +/- 129 micro g/day, below the mean recommended for prevention of neural tube defects. CONCLUSIONS: Voluntary fortification of food with folate is associated with improved folate status in South Australian children and adolescents, but may not be sufficient at current levels to provide maximal protection against neural tube defects at a population level.

Serum creatine kinase levels parallel the clinical course for rhabdomyomatous Wilms tumor.

A right-sided renal mass in an 11-month-old girl was diagnosed by percutaneous needle biopsy as Wilms tumor, which on histologic examination was found to be predominantly rhabdomyomatous. As part of the examination, serum creatine kinase (CK) and CK-MB levels were measured and were significantly elevated at 994 U/L (reference range, 42-180 U/L) and 40 U/L (reference range, 0-3 U/L), respectively. Subsequently, an 8-month-old girl was admitted to the hospital with septicemia and was found to have an abdominal mass. A diagnosis of bilateral Wilms tumor was made following percutaneous biopsy of both kidneys; histologic examination confirmed that the tumor was predominantly rhabdomyomatous. Serum CK and CK-MB levels also were measured and were significantly elevated at 685 U/L and 84.4 U/L, respectively. In both cases, the serum CK and CK-MB levels reflected the clinical course; elevation in serum levels was associated with tumor recurrence, infarction, or chemotherapy-related necrosis. We conclude that these enzymes have clinical usefulness as markers for Wilms tumor showing rhabdomyomatous morphologic features.

Hepatocyte growth factor in human semen and its association with semen parameters.

Hepatocyte growth factor (HGF) is a structurally unique growth factor with potent motogenic (motility inducing) effects. Studies in the murine male genital tract have suggested important associations between HGF and the acquisition of sperm motility during epididymal maturation. The aim of this study was, therefore, to determine the concentration of HGF in human semen and assess its correlation, if any, with sperm motility and other semen parameters. Semen samples were collected by masturbation and analysed using standard procedures. HGF concentrations were measured in duplicate using an enzyme-linked immunoassay technique. Total protein estimations were also made in a subset of samples. The 95 subjects were divided into three groups for analysis: normozoospermic, subnormal semen and azoospermic. HGF was detected in all samples (median 0.456, 25th centile 0.388, 75th centile 0.556 ng/ml). No significant correlations were found between semen HGF concentrations and sperm concentration, motility, total sperm count or total motile count. There were no significant differences in mean HGF concentrations between the three subgroups. In conclusion HGF is present in human semen in significant quantities. The data do not suggest HGF concentrations are correlated with parameters of sperm motility.

Treatment of late-onset nonketotic hyperglycinaemia: effectiveness of imipramine and benzoate.

We report a patient with late-onset nonketotic hyperglycinaemia managed with a sequential approach to drug therapy in placebo-controlled therapeutic trials. Partial response to low-protein diet and sodium benzoate and dramatic response to imipramine are demonstrated, with parental scores on the Developmental Behavioural Checklist falling from the 86th centile before treatment to normal with combined benzoate and imipramine therapy.
