    Notes: Abstract We report on 46,XX true hermaphroditism and 46,XX maleness coexisting in the same pedigree, with maternal as well as paternal transmission of the disorder. Molecular genetic analysis showed that both hermaphrodites as well as the 46,XX male were negative for Y-chromosomal sequences. Thus, this pedigree is highly informative and allows the following conclusions: first, the maternal as well as paternal transmission of the disorder allows the possibility of an autosomal dominant as well as an X-chromosomal dominant mode of inheritance; second, testicular determination in the absence of Y-specific sequences in familial 46,XX true hermaphrodites as well as in 46,XX males seems to be due to the varying expression of the same genetic defect; and third, there is incomplete penetrance of the defect.

    Notes: Abstract Microalbuminura (MA) was determined in 127 children and adolescents (age 3–21 years) with type 1 (insulin-dependent) diabetes mellitus. Patients with clinical evidence of long-term complications or macroproteinuria were excluded. Urinary albumin excretion was measured in a nocturnal 12-h collection and correlated with the albumin/creatinine ratio of a urine sample freshly voided on the morning immediately following the collection. The patients were divided into group A (n=83, age 〈16 years, duration of diabetes 1–13 years, mean 4.4) and group B (n=44, age 〉16 years, duration of diabetes 1–19 years, mean 8.7) and compared with appropriate controls. MA above 15 μg/min was present in 11 of 83 (13.3%) patients in group A and in 7 of 44 (15.9%) in group B. In a repeat urine collection at least 3 months later elevated MA persisted in 1 of 11 (group A) and in 4 of 7 (group B) patients. There was no correlation between increased MA in a 12-h urine collection and the albumin/creatinine ratio in a subsequently voided urine sample. MA was not strictly dependent on age, sex, duration of diabetes, haemoglobin A1, mean arterial blood pressure, plasma creatinine, creatinine clearance or serum beta-2-microglobulin. Further systematic studies and careful follow up are necessary to appraise whether intermittent MA is indeed an early manifestation of incipient kidney disease in children with type 1 diabetes.

    Notes: Abstract We report on 49 boys with constitutional growth delay (CGD) who were initially seen in our clinic at a mean chronological age of 13.3 years (range, 7.3–16.4) and a bone age of 11.1 years (range, 6.0–13.5). All were below the 5th height percentile for chronological age. A positive family history with delayed growth and puberty in one or both parents could be elicited in 75%. All 49 patients were re-examined at a mean age of 22.9 years (range, 20.4–31.2). Measured final height was 171.3 cm (range, 161.2–181.7), which was slightly, but significantly lower than mean target height of 173.0 cm. Final height expressed as standard deviation score (SDS) of a male adult population standard was –1.0 (range, –2.4 to +0.5) , also significantly lower than initial height SDS related to bone age (SDSBA) of –0.5 (range, –1.6 to +1.2). If related to target height (Tanner), final height was found to correlate positively with the initial bone age deficit and the initial height SDSBA. Observed final height was also compared with the predicted adult height by the methods of Bayley-Pinneau (BP), Tanner-Whitehouse Mark II (TW II) and Roche-Wainer-Thissen. Regression equations between all three prediction methods and final height showed an excellent correlation (P 〈 0.0001). However, only by the BP method was predicted height very close to and no different from measured final height (paired t-test). Despite this, final height in 16 of 49 patients (32.6%) differed by more than 5.0 cm from BP predicted height. An overwhelming majority of the patients (88.6%) expressed complete or reasonable satisfaction with their adult height. Conclusion In our sample of male patients with CGD, adult height came close to but did not quite reach mean target height. The BP prediction method offers a good compromise between simplicity and accuracy but must be used judiciously because individual discrepancies with attained final height may be large and unexplained.

    Notes: Abstract Female patients with congenital adrenal hyperplasia have been frequently studied in order to determine the impact of prenatal androgen exposure on various aspects of psychological, psychosocial and psychosexual development. There is no published study to evaluate the impact of the genital malformation, genital operations and chronic medication on the quality of life in adult females with congenital adrenal hyperplasia. We performed a quality-of-life evaluation in adult female patients with congenital adrenal hyperplasia due to a 21-hydroxylation defect. The patients were asked to fill out questionnaires covering the four domains of health-related quality of life, namely physical state, psychological well-being, social relationships and functional capacity as well as questionnaires covering the areas of psychosexual identification and psychosocial integration. In addition a semistructured interview was performed covering medical history as well as physical, emotional, social and psychosexual development. The results were evaluated using a computerized statistical program for social sciences. Forty-five patients agreed to participate (44 could be interviewed) and their medical data did not differ from the 20 patients (medical data were available from 16 patients) who refused to participate. Median age at diagnosis was below 1 year in 54.8 of the participating patients; range was from 0 to 30 years. Of the participants, 48.6%, 34.2% and 17.2% suffered from the simple-virilizing-, salt-wasting-, and late-onset-form of congenital adrenal hyperplasia, respectively. The mean adult height was 157.8 cm, and mean weight was 56.8 kg. In 35.7% the degree of genital virilization was classified as Prader stage 3 or 4. The patients with the salt-wasting form were significantly more virilized at birth than those with the simple-virilizing form resulting in more genital operations and more complications in later life. The patients differed significantly from controls in certain aspects. They were more often single (47.8% vs 66.7%) and had less children (22.2% vs 38.6%). Patients with the salt-wasting form of congenital adrenal hyperplasia also had more problems in establishing heterosexual relationships and conceiving and bearing children. Homosexual preference was not increased. In addition, significant impairments were found with regard to psychosexual identification, but they were successful in terms of adjustment to illness and in receiving social support. The overall quality of life was not significantly different in patients and controls. Even though the patients suffered from a chronic illness and congenital malformations which significantly disturbed their body image, female identity and psychosexual identification, no effect on the overall quality of life could be detected. The differences found regarding social support and illness processing may be mechanisms which they have developed to enable them to cope. These mechanisms seem to be helpful and necessary to maintain a high level of well-being despite impairment, which is in turn reflected by a high quality of life.

    Notes: Abstract Septo-optic dysplasia (SOD) is characterized by hypoplasia of the optic nerve, various types of forebrain defects and hormonal deficiencies. We have studied the clinical and endocrinological characteristics of 18 such patients retrospectively to: (1) better define the endocrine abnormalities in children with SOD; and (2) to find approaches for the interdisciplinary long-term care of children with SOD. The children were seen at the Children's Hospital of the University of Munich from 1976 to 1992 (8 boys, 10 girls; age at initial presentation: 1 day–13 years of age, mean 1.9 years). Unilateral hypoplasia of the optic nerve was found in 7 cases, bilateral hypoplasia in 11. Sonographic, CCT or MRI yielded the following results: 4 of the patients had a cavum septum pellucidum, 3 patients had hypoplasia of the cerebellum, 1 aplasia of the corpus callosum and 1 aplasia of the fornix. An empty sella with or without an ectopic pituitary was seen in 4 cases. Height standard deviation score (SDS) at time of diagnosis was −4.0 to +0.4, mean −2.92. Endocrine deficiencies were present in all 11 patients who had undergone endocrinological investigations. Seven patients suffered from isolated growth hormone (GH) deficiency or multiple hypopituitarism. One had diabetes insipidus centralis, 2 had hypogonadotropic hypogonadism, 1 had hypothyroidism and 2 adrenal insufficiency. Hypothalamic testing was performed only in a subset of patients: in 5 of 11 children tested a thyrotropin releasing hormone (TRH test), in two out of nine a gonadotropin releasing hormone (GnRH) test, and in three out of six GH releasing hormone (GHRH) test yielded abnormal results. High prolactin levels were measured in two out of five patients. Conclusion SOD is characterized by optic nerve hypoplasia and a variety of endocrine deficiencies. In addition, forebrain malformations are present in most SOD patients. Hormonal disorders are present in some SOD patients which may be of hypothalamic origin and need to be investigated systematically.

    Notes: Abstract Eleven patients under 16 years of age, 5 males and 6 females were diagnosed with thyroid carcinoma in our hospital between 1974 and 1992. Median age at diagnosis was 9.5 years (range: 5.2–15.7 years). The presenting sign was a single thyroid nodule in 5, multiple thyroid nodules in 1, cervical adenopathy in 3, and thyroid nodules in conjunction with cervical adenopathy in 2 patients. Histological diagnosis was papillary carcinoma in 5 cases, follicular carcinoma in 2, mixed papillary-follicular carcinoma in 3, and anaplastic carcinoma in one. Only 4 patients had no extrathyroidal metastases at diagnosis. All but one subjects underwent total thyroidectomy, either one-staged or two-staged. If metastases were present, ablative radio-iodine therapy followed. Two patients died within a few months, one from complications of lung metastases, another from diffuse spread of anaplastic carcinoma. Two patients were lost to follow up; 7 patients have been followed for 9.0–18.0 years. Of these, one patient with initial lung metastases has had six recurrences which were successfully treated each time with radio-iodine although thyroglobulin levels remained elevated; another patient who had an initial subtotal thyroidectomy incurred a relapse 12 years later during pregnancy but is doing well now after more intensive surgery. We propose that children with differentiated thyroid carcinoma should undergo total thyroidectomy and selective lymph node extirpation by a skilled surgeon followed by whole body radio-iodine scan and ablative radio-iodine treatment if necessary. Plasma thyroglobulin can then be used as a tumour marker and suppressive levothyroxine does should be given.

    Notes: Abstract Short stature and precocious puberty are frequently found in children with hydrocephalus and/or meningomyelocele (MMC). However, aetiology and pathophysiology have not been well characterized. In this study, 108 patients aged between 3 and 17.8 years were evaluated. Growth was documented on the basis of arm span measurements. Short arm span was found in 47 (43.5%) children with hydrocephalus and/or MMC. Mean arm span was −2.0 standard deviation score (SDS) (−6.4 to +0.8) in 43 girls and −1.4 SDS (−5.6 to +1.3) in 65 boys. When growth deficiency (more than −2.0 SDS) was diagnosed by arm span measurement (24 F, 23 M) or when early sexual maturation was found (6 F, 9 M), endocrine evaluation followed. Levels of serum insulin-like growth factor and insulin-like growth factor binding protein-3 were low in 22 of 62 (33.8%) patients. In 9 of 62 (14.5%) patients, insulin-like growth factor-1 and insulin-like growth factor binding protein-3 levels were found to be increased. Growth hormone (GH) deficiency was diagnosed by means of two different stimulation tests (clonidine and arginine) in 7 of 62 (11.3%) patients. In another 3 of 62 (4.8%) children, 12 h night time GH sampling showed low maximum peak levels and decreased area under the curve values, suggesting neurosecretory GH dysfunction. Precocious puberty or early onset of puberty associated with elevated luteinising hormone and follicle stimulating hormone concentrations after stimulation with luteinising hormone releasing hormone was found in 13 of 108 (12.0%) patients (age 7–9 years). Free thyroxine was abnormally low in 2 of 62 (3.2%) patients. Cortisol was within the normal range in all 62 (100%) tested patients. Conclusions Short arm span in children with hydrocephalus and/or MMC is frequently accompanied by GH deficiency or neurosecretory GH dysfunction. Early onset of puberty is another frequent finding. Both hormonal disorders may be the consequence of damage to the hypothalamus or the pituitary gland caused by increased intracerebral pressure or increased mass of cerebrospinal fluid.
