Abstract
OBJECTIVE To evaluate clinical characteristics of patients with central congenital hypothyroidism (CH), detected in the Dutch neonatal screening program. This included patients with isolated central CH but the majority have multiple pituitary hormone deficiencies (MPHD). DESIGN Nationwide, cross-sectional study. METHODS Data was collected on clinical characteristics, endocrine tests and neuroimaging of central CH patients, detected by the Dutch neonatal screening and born between 1 January 1995 and 1 January 2015. Height and pubertal status were assessed during a study visit. Isolated central CH patients without a confirmed genetic diagnosis were offered genetic (re-)testing. RESULTS During the 20-year period 154 central CH patients were detected (incidence of permanent central CH 1:25 642). After excluding deceased (15), severe syndromic (7) and transient patients (6), 92 of 126 eligible patients were included (57 MPHD; 79% male). Sixty-one patients (50 MPHD) had been hospitalized before screening results were reported, but central CH was diagnosed on clinical grounds in only three of them (5%). MRI abnormalities consistent with pituitary stalk interruption syndrome were seen in 50 (93%) MPHD patients. Among isolated central CH patients, 27 (84%) had an IGSF1, TBL1X or IRS4 gene variant (53, 16 and 16%, respectively). CONCLUSION Many patients with central CH have neonatal health problems, especially MPHD patients. Despite hospital admission of two-thirds of patients, almost none were diagnosed clinically, but only after the notification of an abnormal screening result was received. This indicates that central CH, especially if isolated, is an easily missed clinical diagnosis.

Abstract
OBJECTIVE To provide an overview of cognitive and motor outcome, and quality of life (QoL) in patients with congenital central hypothyroidism (CH-C). DESIGN Systematic review with individual patient data (IPD) meta-analysis. METHODS OVID MEDLINE, EMBASE and PsycInfo were searched from inception to June 11th, 2019. Studies in patients with CH-C, either isolated or with multiple pituitary hormone deficiency (MPHD), were included if CH-C patients could be separated from any additional patient groups. Primary outcomes were full-scale intelligence quotient (FSIQ) and motor outcome; secondary outcome was QoL. Following data-extraction, one-stage IPD meta-analysis was performed, fitting a linear mixed model with FSIQ as dependent variable. Random intercepts were fitted for each study. RESULTS Six studies measuring FSIQ were eligible for meta-analysis, comprising 30 CH-C patients (20 males; 27 MPHD patients). FSIQ range was wide (64-123). Mean weighted FSIQ was 97 (95% CI: 88-105). Twenty-seven percent had an FSIQ below 85 (≥1 s.d. below norm score), and 10% below 70 (≥2 s.d. below norm score). There was no significant association between FSIQ and sex or age. Age at treatment initiation was available from three studies only, thus impeding a reliable analysis of this parameter. Motor outcome and QoL were each studied in one study; no quantitative analyses could be performed for these outcomes. CONCLUSION A wide range in FSIQ scores was observed in CH-C patients. Results should be interpreted with caution, because included patients mainly had MPHD and age at treatment initiation was unknown for the majority of patients.

Abstract
CONTEXT Longitudinal data on bone mineral density (BMD) in children and adolescents with Prader-Willi Syndrome (PWS) during long-term GH treatment are not available. OBJECTIVE This study aimed to determine effects of long-term GH treatment and puberty on BMD of total body (BMDTB), lumbar spine (BMDLS), and bone mineral apparent density of the lumbar spine (BMADLS) in children with PWS. DESIGN AND SETTING This was a prospective longitudinal study of a Dutch PWS cohort. PARTICIPANTS Seventy-seven children with PWS who remained prepubertal during GH treatment for 4 years and 64 children with PWS who received GH treatment for 9 years participated in the study. INTERVENTION The children received GH treatment, 1 mg/m(2)/day (≅ 0.035 mg/kg/d). MAIN OUTCOME MEASURES BMDTB, BMDLS, and BMADLS was measured by using the same dual-energy x-ray absorptiometry machine for all annual measurements. RESULTS In the prepubertal group, BMDTB standard deviation score (SDS) and BMDLSSDS significantly increased during 4 years of GH treatment whereas BMADLSSDS remained stable. During adolescence, BMDTBSDS and BMADLSSDS decreased significantly, in girls from the age of 11 years and in boys from the ages of 14 and 16 years, respectively, but all BMD parameters remained within the normal range. Higher Tanner stages tended to be associated with lower BMDTBSDS (P = .083) and a significantly lower BMADLSSDS (P = .016). After 9 years of GH treatment, lean body mass SDS was the most powerful predictor of BMDTBSDS and BMDLSSDS in adolescents with PWS. CONCLUSIONS This long-term GH study demonstrates that BMDTB, BMDLS, and BMADLS remain stable in prepubertal children with PWS but decreases during adolescence, parallel to incomplete pubertal development. Based on our findings, clinicians should start sex hormone therapy from the age of 11 years in girls and 14 years in boys unless there is a normal progression of puberty.

Abstract
BACKGROUND The most important reason for treating children with Prader-Willi syndrome (PWS) with GH is to optimize their body composition. OBJECTIVES The aim of this ongoing study was to determine whether long-term GH treatment can counteract the clinical course of increasing obesity in PWS by maintaining the improved body composition brought during early treatment. SETTING This was a multicenter prospective cohort study. METHODS We have been following 60 prepubertal children for 8 years of continuous GH treatment (1 mg/m(2)/d ≈ 0.035 mg/kg/d) and used the same dual-energy x-ray absorptiometry machine for annual measurements of lean body mass and percent fat. RESULTS After a significant increase during the first year of GH treatment (P < .0001), lean body mass remained stable for 7 years at a level above baseline (P < .0001). After a significant decrease in the first year, percent fat SD score (SDS) and body mass index SDS remained stable at a level not significantly higher than at baseline (P = .06, P = .14, resp.). However, body mass index SDSPWS was significantly lower after 8 years of GH treatment than at baseline (P < .0001). After 8 years of treatment, height SDS and head circumference SDS had completely normalized. IGF-1 SDS increased to +2.36 SDS during the first year of treatment (P < .0001) and remained stable since then. GH treatment did not adversely affect glucose homeostasis, serum lipids, blood pressure, and bone maturation. CONCLUSION This 8-year study demonstrates that GH treatment is a potent force for counteracting the clinical course of obesity in children with PWS.

Abstract
A 14-year-old girl with Graves' disease developed a fever, sore throat and a severe systemic infection after being treated with antithyroid drugs for 1 year. Agranulocytosis was diagnosed. After long-term antibiotic treatment and supportive therapy she recovered. Agranulocytosis is a known side-effect of antithyroid drugs and is seen in 0.2 to 0.5% of the patients. It usually occurs within the first 3 months of treatment. Patients above the age of 40 seem to be more susceptible. Since the onset of agranulocytosis is relatively acute, routine blood monitoring is not very useful. It is more important to instruct patients who use a thyreostatic to contact their physician in case of unexplained fever or a sore throat.

Abstract
A diagnosis of intracranial actinomycosis was made in a 9-year-old boy with headache, cranial nerve dysfunction and ataxia. Poor dental hygiene leading to caries and an inflammation in his right upper jaw probably was the cause of cervicofacial actinomycosis with intracranial extension. A full recovery was achieved by treatment with benzylpenicillin. Actinomyces is a gram-positive bacterium belonging to the endogenous flora of the mucous membranes of the oropharynx, gastrointestinal tract, and female genital tract. Disruption of the mucous membrane is the portal of entry for an extremely destructive infective process that is effectively treated with penicillin. Good orodental hygiene is important for the prevention of actinomycosis.
