[Diabetes, not harmless in young adults]. / Diabetes, ook bij jongvolwassenen niet onschuldig.

A recent publication in JAMA again demonstrates that a significant proportion of young adults with type-1 or type-2 diabetes develop diabetes-related complications and comorbidities. These complications and comorbidities already occur after a relative short disease duration and is most frequently seen in young adults with type-2 diabetes. Future research should focus on medical, social and psychological factors that will improve diabetes care.

[Measles after MMR-vaccination]. / 'De mazelen' na bmr-vaccinatie.

BACKGROUND: The Dutch national vaccination program provides vaccination for mumps, measles and rubella (MMR vaccine) for all children. After vaccination with live attenuated viruses, the virus replicates on a limited scale. Replication may lead to mild symptoms occurring 5-14 days after MMR-vaccination, including fever, conjunctivitis and rash. Symptoms are comparable to those of a wildtype measles infection. CASE DESCRIPTION: A 14-month-old boy was admitted to the hospital with an impressive rash 13 days after MMR-vaccination. Diagnostic tests were positive for measles. This test result caused the mother to doubt further vaccination. CONCLUSION: Within 14 days after MMR-vaccination, a child can present with symptoms very similar to a wildtype measles virus infection. The low incidence of wildtype measles infection strongly suggests that these symptoms will likely be a reaction to vaccination. Elaborate diagnostic procedures may cause the parents a lot of stress and therefore offering reassurance to parents may be more appropriate.

Severe neonatal complication of transverse lie after preterm premature rupture of membranes.

Both transverse lie and preterm premature rupture of membranes (PPROM) are associated with neonatal morbidity and mortality. We present a neonate born at 29 weeks gestation with severe birth trauma after PPROM and transverse lie. The patient had extensive swelling and areas of desquamated and necrotic skin of the right lower limb. Neonatal compartment syndrome (NCS) was suspected. Perfusion of the limb improved after decompressing subcutaneous incisions. A fetus in transverse lie may be mechanically damaged in the case of PPROM, especially at an early gestational age. Early recognition is of great interest in the management and prognosis of NCS.

Genetic and epigenetic variability in the gene for IGFBP-3 (IGFBP3): correlation with serum IGFBP-3 levels and growth in short children born small for gestational age.

CONTEXT: IGF-I and IGFBP-3 play a central role in fetal and postnatal growth and levels are low in short SGA children. The -202 A/C and -185 C/T SNPs are located near elements involved in directing IGFBP3 promoter activity and expression. Changes in promoter CpG methylation status affect transcription factor binding and transcriptional activation of IGFBP3 in vitro. OBJECTIVE: To assess the relationship between IGFBP3 promoter SNPs, IGFBP-3 levels, spontaneous growth and growth response to GH treatment in short prepubertal SGA children. To assess promoter methylation status in a subgroup of short SGA subjects and controls. PATIENTS: 292 Short prepubertal SGA children, 39 short young SGA adults and 85 young adults with normal stature. INTERVENTION: Short prepubertal SGA children received GH 1mg/m(2)/day. OUTCOME MEASURES: Fasting levels of IGF-I and IGFBP-3, baseline and delta height SDS. RESULTS: At baseline, IGFBP-3 levels were highest in SGA children with -202 AA genotype and lower in children with 1 or 2 copies of the C-allele (P<0.001). Children with C(-202)/C(-185) haplotype, compared to children with A(-202)/C(-185) haplotype, had lower IGFBP-3 levels (P=0.003) and were shorter (P=0.03). During GH treatment, children with C(-202)/C(-185) haplotype showed a significantly greater increase in IGFBP-3 SDS and in height SDS than children with A(-202)/C(-185) haplotype, resulting in similar IGFBP-3 levels and similar height SDS after 12 months of GH treatment. CpG methylation patterns showed a trend towards more methylation of CpGs involved in transcription factor binding in short young SGA adults compared to controls. CONCLUSION: Polymorphic variation in the IGFBP3 promoter region is correlated with IGFBP-3 levels, spontaneous growth and response to GH treatment in short SGA children.

Thyroid function in short children born small-for-gestational age (SGA) before and during GH treatment.

CONTEXT: Disturbances in thyroid function have been described in small-for-gestational age (SGA) children but the influence of prematurity is unclear. In addition, the effect of GH treatment on thyroid function has not been studied in short SGA children. OBJECTIVES: To determine whether short SGA children have higher TSH levels compared to age-matched controls and evaluate the influence of gestational age. To investigate whether GH treatment alters thyroid function. PATIENTS: A total of 264 short SGA children (116 preterm), prepubertal and non-GH deficient. MEASUREMENTS: Serum FT4 and TSH at baseline and after 6, 12 and 24 months of GH treatment. RESULTS: Baseline mean TSH was higher in preterm short SGA children than in age-matched controls (P < 0.05). Mean FT4 was not significantly different between short SGA children and controls. Baseline FT4 or TSH did not correlate with gestational age, or SDS for birth weight, birth length, height, body mass index, IGF-I or IGFBP-3. Mean FT4 decreased significantly during the first 6 months of GH treatment, but remained within the normal range. TSH did not change during treatment. The change in FT4 did not correlate with the change in height SDS during 24 months of GH treatment. CONCLUSION: Preterm short SGA children have higher, although within the normal range, TSH levels than controls. The level of TSH does not correlate with gestational age, birth weight SDS or birth length SDS. FT4 decreases during GH treatment, but is neither associated with an increase in TSH nor does it affect the response to GH treatment. As these mild alterations in thyroid function do not appear clinically relevant, frequent monitoring of thyroid function during GH therapy is not warranted in short SGA children.

Procalcitonin as a prognostic marker in meningococcal disease.

OBJECTIVE: To assess the prognostic value of procalcitonin levels during the clinical course of meningococcal disease in children. DESIGN: A retrospective, descriptive study. SETTING: University paediatric intensive care unit. PATIENTS: Nine patients with meningococcal sepsis and 55 patients with meningococcal septic shock were included in the study, giving a total of 64. MEASUREMENTS AND RESULTS: Procalcitonin (PCT), C-reactive protein (CRP), cytokines (IL-6, IL-8 and TNF-alpha), plasminogen activator inhibitor-1 (PAI-1) and several routine laboratory parameters were determined and expressed as medians (ranges). PCT levels on hospitalisation were elevated in all children as compared to normal values. Median PCT levels on admission were significantly higher in children with septic shock than in children with sepsis (270 ng/ml (5.7-672.3) versus 64.4 (20.6-283.7); p<0.01). When the patients were categorised to severity using the Pediatric Risk of Mortality (PRISM) score (group 1: <15 points, group 2: 16-30, group 3: >30), the PCT levels were significantly different in the three groups. All markers, with the exception of PCT (p=0.056), were significantly different between survivors and non-survivors. When the duration of petechiae was taken into account, the difference in PCT levels became significant (p=0.04). CONCLUSIONS: Procalcitonin levels on admission are related to severity. In the case of a short disease history (duration of petechiae), PCT levels are also related to mortality. Although PCT levels are elevated in all patients, the levels per se do not allow a prediction about survival versus non-survival, this is in contrast to other markers and scores (PRISM).
