Growth and pituitary-adrenal function in children with severe asthma treated with inhaled budesonide.

BACKGROUND: The increased use of inhaled corticosteroids in the management of asthma raises concern about the safety of these drugs in children. We sought to determine the safety of long-term administration of inhaled budesonide in young children with asthma. METHODS: We studied 15 children 2 to 7 years old who had severe perennial asthma. They inhaled 100 micrograms of budesonide twice daily for three to five years. Efficacy was assessed by serial evaluation of respiratory symptoms and the need for other medications, and safety by serial evaluation of height, height velocity, weight, bone age, and pituitary-adrenal function. RESULTS: The severity of asthma decreased within the first month after the initiation of therapy, as demonstrated by a 58 percent reduction in the number of days with symptoms of asthma and a 75 percent decrease in the use of bronchodilators. This improvement was maintained thereafter. The growth pattern of all patients, including their height, weight, and bone age, was normal (as compared with standard normal values) throughout the treatment period. Pituitary-adrenal function was not adversely affected by the treatment, as demonstrated by normal serum cortisol concentrations in the morning and 60 minutes after stimulation with corticotropin, normal 24-hour serum cortisol concentrations (mean [+/- SD] of samples collected at 30-minute intervals for 24 hours, 8.4 +/- 4.2 micrograms per deciliter [232 +/- 116 nmol per liter]), and normal urinary cortisol excretion (34 +/- 9 micrograms [95 +/- 25 nmol] per day). CONCLUSIONS: Prolonged administration of 200 micrograms of inhaled budesonide daily to young children with severe asthma does not impair growth or pituitary-adrenal function.

Váradi syndrome (OFD VI) or Opitz trigonocephaly syndrome: overlapping manifestations in two cousins.

We report on 2 cousins, offspring of consanguineous matings, with multiple congenital anomalies. Square face, frontal bossing with metopic ridge, small anteverted nose, flat nasal bridge, slanted palpebral fissures, and epicanthal folds contributed to an unusual appearance. Multiple bucco-alveolar frenula and notched inferior alveolar ridges were present at birth and one had a notched uvula and submucous cleft of the hard palate. Both had congenital heart anomalies, micropenis, and cryptorchidism. Persistence of Müllerian structures was documented at necropsy in one patient. The surviving patient was mentally retarded and had unilateral central hexadactyly and partial agenesis of the corpus callosum. Bulimia and episodic hyperthermia were attributed to hypothalamic dysfunction. Results of unstimulated endocrine studies and gonadotropin releasing hormone (GnRH), and human chorionic gonadotropin (HCG) stimulation tests were normal. The manifestations of the 2 patients overlap those reported in the OFD VI and Opitz trigonocephaly syndromes.

Familial isolated growth-hormone deficiency with advanced sexual maturation.

Two brothers, aged 15 1/2 and 13 1/2 years, with dwarfism, microcephaly, and advanced sexual and skeletal maturation are described. One patient was mentally retarded. The parents were first cousins. Endocrine studies of these patients documented low growth-hormone levels after clonidine and insulin stimulation and blunted growth-hormone response to growth hormone releasing hormone. Gonadotropin releasing hormone stimulation produced no changes in levels of luteinizing and follicle-stimulating hormones. Basal levels of 17-alpha-hydroxyprogesterone were elevated in the two patients and increased further in response to stimulation with corticotropin. Levels of testosterone, dehydroepiandrosterone sulfate, and androstenedione were variably increased in both patients and showed a proportional increase on stimulation with human chorionic gonadotropin. To our knowledge, this is the first report of a familial association between growth-hormone deficiency and advanced bone and sexual maturation. A pituitary and an independent adrenal defect could account for the observations in these patients, but in view of the familial recurrence, a common underlying defect is possible.

Extraordinary daytime urinary frequency in children.

BACKGROUND: Sudden onset of daytime urinary frequency of a small amount of urine in a previously toilet-trained child can be a disturbing problem. Psychosocial problems, problems at school, or problems within the family have to be taken into consideration. METHODS: Fifteen children with sudden onset of isolated daytime urinary frequency were evaluated and followed for a period of 12 to 18 months. A thorough medical and family history was obtained for each child, with special attention given to any psychosocial problems the child had experienced. All the children underwent a physical examination, complete urinalysis, and ultrasonography of the kidneys and bladder. RESULTS: In all of the patients, the urinalysis and ultrasonographic findings were within normal limits. A trigger factor was identified as the cause of urinary frequency in each case. CONCLUSIONS: Because urinary frequency is usually a benign self-limited condition, an extensive urological evaluation is not indicated. In most cases, providing reassurance to the parents and the child is the only intervention necessary.

Ambiguous genitalia in the Proteus syndrome.

An 11-year-old girl was followed up since birth because of hemihypertrophy of the left leg and thigh, multiple pigmented nevi and subcutaneous tumors typical of the Proteus syndrome. Because of clitoromegaly and scrotal-like hypertrophy of the labia majora, she had an endocrine evaluation the results of which were normal. The findings are thought to represent local genital hypertrophy. Ambiguous genitalia have to be added to the phenotype of the Proteus syndrome.

Familial simple hypohidrosis with abnormal palmar dermal ridges.

A brother and sister born to nonconsanguineous, Iranian Jewish parents were found to have simple hypohidrosis. Pilocarpine produced only little sweating, and external heat and physical effort were associated with elevation of body temperature. Abnormal palmar dermal ridges were considered to be associated with paucity of sweat pores and glands. Biopsy supported this view since only one normal sweat gland and duct was found in a 5 mm punch.

Familial lipoid adrenal hyperplasia: genetic marker data and an approach to prenatal diagnosis.

Some of the anatomic endocrine, and genetic aspects of lipoid adrenal hyperplasia were studied in an inbred Israeli-Arab family with two affected sibs. One sib, a genetic female, presented with acute Addisonian crisis. Endocrine studies documented elevated ACTH levels and no detectable steroids of gonadal or adrenal origin. The other patient, a male pseudo-hermaphrodite, was found at autopsy to have typical lipoid adrenal hyperplasia and ectopic adrenal tissue adjacent to an intra-abdominal testicle. Complete vagina, uterus, and fallopian tubes were present in addition to the Wolffian structures. This unique observation supports the view that steroids may be necessary for Müllerian inhibitory factor to induce regression of Müllerian structures. The segregation of 27 autosomal markers was studied in one affected and five unaffected sibs. Genetic linkage to HLA, MNS, and GPT is unlikely. In addition, the affected sib is heterozygote for a haplotype of chromosome 1 which includes the Rh, Fy, PGM-1 systems. Determination of fetal gender by the combined use of ultrasonography and amniocentesis is suggested for prenatal diagnosis and improved risk counselling.

Oculo-palato-cerebral dwarfism: a new syndrome.

Three of four offspring of consanguineous parents presented a unique association of microcephaly, mental retardation, spasticity, connective tissue abnormalities, cleft palate, persistent hypertrophic primary vitreous, and short stature. In one patient brain atrophy was documented. All the affected individuals had severe asthma and it is thought that the asthma is associated with the syndrome complex. Genetic transmission is most likely autosomal recessive. We believe this constellation of findings to be a new genetic syndrome and have termed it the oculo-palato-cerebral dwarfism syndrome.

Trigonocephaly: a new familial syndrome.

Trigonocephaly was found in six relatives through three generations of one family. The propositus was ascertained at birth because of omphalocele. In addition to trigonocephaly, he had minor ear, vertebral, and genital abnormalities. His father had mild microcephaly, and both had minor eye abnormalities. None of the other four affected individuals had any other malformations. In this family, trigonocephaly is an autosomal dominant trait. The ratio of affected males to affected females was 5 to 1, and although the paucity of affected females is not statistically significant, we speculate that it may reflect variable expressivity or sex limitation of the trait. We conclude that the condition in this family represents a unique syndrome in which trigonocephaly is not associated with functional brain abnormalities and where craniosynostosis is limited to the metopic region.

XY gonadal dysgenesis associated with the congenital nephrotic syndrome.

The occurrence of a nephrotic syndrome in a female infant with a 46,XY karyotype is reported. The internal genitalia were female but a microscopic region of immature testicular tissue was present in 1 of 2 streak gonads. The relationship of this child's abnormal genital differentiation to her renal disease is discussed in the light of reported cases of infantile nephritis and Wilms' tumor in male pseudohermaphrodites. It is suggested that a common teratogen operating on the embryonic urogenital ridge may cause both genital and renal anomalies.

Congenital hypopituitarism in female infants. Its association with hypoglycemia and hypothyroidism.

Congenital hypopituitarism was found in two female infants who had profound hypoglycemia and hypothyroidism. In both infants, death occurred despite recognition of the disorder and institution of appropriate therapy. Autopsy findings showed an absent pituitary gland and sella turcica, with hypoplastic adrenal and thyroid glands, and ovaries in one case, and pituitary gland aplasia with absent thyroid and right adrenal glands plus a hypoplastic left adrenal gland in the other case.

Adolescent secondary amenorrhea: association with hypothalamic hypothyroidism.

In adolescent girls, secondary amenorrhea can result from a variety of physiologic and psychologic disturbances. Previous reports associating amenorrhea and primary hypothyroidism have not distinguished between the alternative etiologic roles of thyroxine deficiency and hyperprolactinemia. We have evaluated two girls with secondary amenorrhea who had clinical and chemical evidence of hypothyroidism. Both had low basal T4 values (0.8 and 3.2 microgram/dl), calculated free T4 (0.1 and 0.7 ng/dl), and T3 (51 and 81 ng/dl). Both had undetectable basal TSH with normal TSH response to TRH. Basal FSH and LH values were normal, as was the response to LHRH. Basal prolactin levels were 6 and 14 ng/ml, respectively, and both girls had growth hormone responses of greater than or equal to 15 ng/ml in response to insulin-induced hypoglycemia. Pituitary-adrenal function and reserve were also normal. In neither patient was there any historical, physical, or laboratory features compatible with anorexia nervosa. After treatment with 1-thyroxine, both girls had a resumption in menses. These two adolescent girls thus appear to have isolated hypothalamic hypothyroidism. The associated secondary amenorrhea demonstrates that thyroid deficiency alone, without hyperprolactinemia, can interfere with normal hypothalamic-pituitary-ovarian function.
