HYPERANDROGENISM DUE TO 3-BETA-HYDROXYSTEROID DEHYDROGENASE-DEFICIENCY WITH ACCESSORY ADRENOCORTICAL TISSUE - A HORMONAL AND METABOLIC EVALUATION

1. Adrenal ectopic tissue has been detected in the paragonadal region of normal women. In patients with congenital adrenal hyperplasia due to 21-hydroxylase (21-OH) deficiency, the manifestation of hyperplasia of paragonadal accessory adrenal tissue has been usually reported to occur in males. Probably, this is the first report of a female with 3beta-hydroxysteroid dehydrogenase (3beta-HSD) deficiency with ectopic adrenal tissue in ovaries. However, the occurrence of hyperplasia of adrenal rests among women with classical congenital adrenal hyperplasia may not be rare, especially among patients with a late diagnosis.2. We report a woman with 3beta-HSD deficiency whose definitive diagnosis was made late at 41 years of age immediately before surgery for the removal of a uterine myoma. During surgery, exploration of the abdominal cavity revealed the presence of bilateral accessory adrenal tissue in the ovaries and in the para-aortic region. The patient had extremely high levels of ACTH (137 pmol/l), DHEA (901.0 nmol/l), DHEA-S (55.9 mumol/l), androstenedione (70.2 nmol/l), testosterone (23.0 nmol/l) and 17alpha-hydroxypregnenolone (234.4 nmol/l) suggesting 3beta-HSD deficiency.3. In view of these elevated androgen levels, with an absolute predominance of DHEA and DHEA-S, we evaluated the effect of this hormonal profile on carbohydrate tolerance and insulin response to glucose ingestion.4. The patient presented normal glucose tolerance but her insulin response was lower than that of 14 normal women (area under the curve, 3beta-HSD = 17,680 vs 50,034 pmol/l for the control group over a period of 3 h after glucose ingestion).5. These results support recent data suggesting that patients with increased serum DHEA and DHEA-S levels do not present resistance to insulin.

Relationship between lower-lip fistulae and cleft lip and/or palate in Van der Woude syndrome

Objective: This study was conducted to evaluate the relationship between fistulae of the lower lip and cleft lip and/or palate in patients with Van der Woude syndrome.Methods: the medical records of 11,000 patients with cleft lip and/or palate registered at the Cleft Lip-Palate Research and Rehabilitation Hospital, University of São Paulo, Bauru were reviewed. of these patients, 133 (1.2%) presented with Van der Woude syndrome.Results: of the 133 patients, 88 (66.2%) exhibited full clefts, 22 (16.5%) only cleft lip, and 23 (17.3%) only cleft palate. The lower-lip fistulae observed in these 133 patients were bilateral symmetric in 66 (49.7%), bilateral asymmetric in 42 (31.6%), microform in 19 (14.3%), median in 5 (3.8%), and unilateral in 1 (0.7%).Conclusion: This population sample appears to exhibit the previously published tendency for bilateral, unilateral, or mixed-type congenital fistulae to be associated with cleft lip with or without cleft palate, while so-called microforms or conic elevations are almost exclusively associated with cleft palate.

Hereditary equine regional dermal asthenia in three related Quarter horses in Brazil

Hereditary equine regional dermal asthenia belongs to a group of inherited, congenital connective tissue dysplasias usually described as hyperelastosis cutis, cutaneous asthenia, dermatosparaxis, or Ehlers-Danlos-like syndrome. This report presents the clinical and histological features of three related Quarter horses affected with regional dermal asthenia. These horses had bilateral asymmetric lesions of the trunk and lumbar regions, where the skin was hyperextensible. Handling of the skin elicited a painful response and superficial trauma led to skin wounds. The skin was thinner than normal in the affected areas, with thickened borders and harder fibrotic masses (pseudotumours). The histopathological findings included thinner and smaller collagen fibrils, and a loose arrangement of collagen fibres in the middle, adventitial and deep dermis. Masson's trichrome and Calleja stains did not reveal any abnormality of collagen and elastic fibres. Electron microscopy showed no abnormalities. As in human patients, pseudotumour histopathological findings included fibroplasia and neovascularization. The pedigree chart of these animals supports an autosomal recessive type of inheritance, which has been suggested by other studies. This is the first report of this disease in Brazil. Its clinical and histological features resemble those described in horses affected with this condition in the United States.

Neonatal meningitis according to the microbiological diagnosis: a decade of experience in a tertiary center

The aim of this study was to evaluate the incidence of and mortality due to meningitis and compare data according to microbiological diagnosis. This was a ten-year retrospective study conducted at a neonatal intensive care unit (NICU). Newborns with meningitis confirmed by positive CSF culture were included; those with congenital infection or malformations that made lumbar puncture impossible were excluded. The variables investigated were birth weight, gestational and postnatal age, procedures, hematological and CSF parameters, and complications. Parametric and non-parametric tests were used (statistical value p<0.05). The incidence of meningitis was 0.6% and mortality was 27%. of the 22 cases, 59% involved Gram-negative bacteria; 36% Gram-positive and 5% fungi. The groups did not differ in relation to birth weight, gestational and postnatal age, procedures or hematological and CSF parameters. Sepsis, convulsions and deaths were frequent in both groups, without statistical difference. Gram-negative cases showed abscesses and higher frequency of ventriculitis and hydrocephaly. Meningitis was infrequent, but presented high mortality and frequent complications.

Spondylothoracic dysplasia in two siblings

The spondylothoracic dysplasia syndrome is characterized by congenital malformations of vertebrae and ribs. As a consequence of the anomalous development of the vertebral column, the neck and thorax are short, and the normal head looks as if emerging from the shoulders. The thorax is short and asymmetric with an increased anteroposterior diameter. Dorsolumbar lordosis and a protuberant abdomen are present. The extremities though normal in length appear long relative to the shortened trunk. Short stature results from the vertebral abnormalities. The syndrome was seen in 2 siblings of nonconsanguineous parents.

Ulnar ray a/hypoplasia: evidence for a developmental field defect on the basis of genetic heterogeneity. Report of three Brazilian families.

We report on five Brazilian patients from three unrelated families with congenital anomalies of the upper limbs. Ulnar aplasia/hypoplasia was the main reason for examining these patients. Evidence for existence of an ulnar developmental field is based on genetic heterogeneity. Clinical and genetic aspects of the ulnar ray defects are discussed.

Prevalência de anodontia entre estudantes do 2O grau da cidade de São José dos Campos-Correlação dessa anomalia entre terceiros molares e outros órgão dentários.

The authors studied 201 school children form both sexes, aging 12 to 14 years, in order to identify anodontia, including in third molars. The results indicated a congenital absence of teeth in 24.37% of the examined children, distributed into 10.44% of boys and 13.93% of girls. Anodontia was observed concerning third molar teeth and other teeth, and the correlation was calculated by the total, sex, and hemiarch. The data were presented and discussed, and the results included several conclusions.

Freqüência de raízes fusionadas, separadas divergentes, separadas convergentes, separadas retilíneas e dilaceradas dos terceiros molares.

In a sample of Brazilian white young adults between 18-23 years old, the A.A. studied the third molar roots, in anatomical aspects, using the orthopantomographic radiographic method. They concluded that the superior third molar shows a biggest number of fusionated roots (19.50% in the right side and 19.66% in the left side) and the inferior third molar shows a biggest number of separated roots (21.48% in the right side and 19.66% in the left side).

Incontinentia pigmenti (Bloch-Sulzberger syndrome): a case report.

A syndrome--incontinentia pigmenti--of probable genetic etiology, is discussed and a new case report presented. The syndrome presents systemic and dental manifestations, which are separate although similar to those found in other disease entities, i.e., congenital syphilis, hereditary ectodermal dysplasia.

Obstrução nasolacrimal congênita - Diagnóstico e tratamento

Patients with congenital nasolacrimal obstruction (CNLO) were evaluated at the Lacrimal Apparatus Service of Botucatu Faculty of Medicine - UNESP from 1990 to 1993. 45 children were seen at this period with CNLO. The diagnosis was confirmed by dacryocystography (DCG). Obstruction was unilateral in 77,7% of the patients; 68,1% at Arlt Sinus and 43,6% had lacrimal sac grade 1. Probing was made in children older than 6 months, under general anaesthesia, after DCG was performed. Cure was greater in children age 6 to 12 months with obstruction at Hasner's Valve and without dilation of lacrimal sac.

SINDROME DE DUBOWITZ

A presentation of two cases of Dubowitz syndrome in monozigous twin girls. The syndrome is a rare congenital disorder, the main clinical aspects of which include retarded intrauterine and post-natal growth, microcephaly, peculiar face and an eczemic rash, resulting from photosensitivity of the regions exposed to sunlight.

Fístula arteriovenosa pulmonar maciça. Causa rara, potencialmente curável de hipóxia neonatal.

The case of a six-day-old neonate admitted in an emergency situation because of dyspnea and increasing cyanosis is reported. Despite abnormal opacification on the chest X-ray and left ventricular overload on the electrocardiogram and echocardiogram, features compatible with the disease, the diagnosis of massive pulmonary arteriovenous fistula affecting the whole left superior lobe, was made possible only after necroscopic examination.
