Swimming training exacerbates pathological cardiac hypertrophy in kinin B(2) receptor-deficient mice

Kallikrein-kinin system exerts cardioprotective effects against pathological hypertrophy. These effects are modulated mainly via B(2) receptor activation. Chronic physical exercise can induce physiological cardiac hypertrophy characterized by normal organization of cardiac structure. Therefore, the aim of this work was to verify the influence of kinin B(2) receptor deletion on physiological hypertrophy to exercise stimulus. Animals were submitted to swimming practice for 5 min or for 60 min, 5 days a week, during 1 month and several cardiac parameters were evaluated. Results showed no significantly difference in heart weight between both groups, however an increased left ventricle weight and myocyte diameter were observed after the 60 min swimming protocol, which was more pronounced in B(2)(-/-) mice. In addition, sedentary B(2)(-/-) animals presented higher left ventricle mass when compared to wild-type (WT) mice. An increase in capillary density was observed in exercised animals, however the effect was less pronounced in B(2)(-/-) mice. Collagen, a marker of pathological hypertrophy, was increased in B(2)(-/-) mice submitted to swimming protocol, as well as left ventricular thickness, suggesting that these animals do not respond with physiological hypertrophy for this kind of exercise. In conclusion, our data suggest an important role for the kinin B(2) receptor in physiological cardiac hypertrophy. (c) 2007 Elsevier B.V. All rights reserved.

Oral-Facial-Digital Syndrome Type 1: Oral Features in 12 Patients Submitted to Clinical and Radiographic Examination

Objective: To evaluate the oral features in individuals with oral-facial-digital syndrome type 1 (OFD 1), previously diagnosed by the Genetic Sector of the Hospital of Rehabilitation of Craniofacial Anomalies of the University of São Paulo (HRAC-USP).Design: Twelve patients with OFD 1 were examined clinically and radiographically; their medical files were also evaluated.Results: Associated oral malformations were observed in all patients (100%). The most frequent findings were tongue hamartomas, multiple buccal frena, asymmetric lips, asymmetric tongue, and bilateral maxillary gingival swelling. Interestingly, atrophy of the maxillary midline frenum was also observed in all the individuals examined.Conclusions: Several extra and intraoral alterations were observed in patients with OFD 1. The authors suggest the inclusion of atrophy of the maxillary midline frenum as a commonly found characteristic of OFD 1.

Gorlin-Goltz Syndrome and Neoplasms: A Case Study

Gorlin syndrome is a rare autosomal dominant disorder exhibiting high penetrance and variable expressivity. It is characterized by facial dysmorphism, skeletal anomalies, multiple basal cell carcinomas, odontogenic keratocysts (OKC), palmar and plantar pits, bifid ribs, vertebral anomalies and a variety of other malformations. Various neoplasms', such as medulloblastomas, meningiomas, ovarian and cardiac fibromas are also found in this syndrome. Objective: To describe a twelve-year-old patient with Gorlin-Goltz syndrome, with basal cell carcinomas and promyelocytic leukemia developed after receiving craniospinal radiation for a medulloblastoma. Mild ribs as well as mandibular and maxillar OKC were also diagnosed. Conclusion: The patient with Gorlin-Goltz syndrome should receive close follow-up for early detection of malformations and malignant neoplasias.

Cell-mediated and humoral immunity in West syndrome

The immunological status of five children with West syndrome consequent to previous cerebral lesions was investigated. Three children had West syndrome and two were in transition from West to Lennox-Gastaut syndrome. All of them showed cellular immunological deficiencies in the following tests: sensitization to DNCB, intracutaneous reaction to PHA, inhibition of leukocyte migration, blastic transformation of lymphocytes, T and B lymphocytes in peripheral blood and levels of serum immunoglobulins. These immunological deficiencies, of different degrees of severity, were associated with frequent infections in these children. A possible association between the immunological deficiencies and autoimmunity is discussed.

FG syndrome in a Brazilian child with additional previously unreported signs.

We report on a Brazilian child with typical manifestations of the FG syndrome. Pigmentary dysplasia, metacarpal fusion and peculiar anatomopathological findings are additional undescribed signs.

A case of terminal long arm deletion of chromosome 6

A four-year-old girl with deletion of chromosomal band 6q24 → qter is described. Clinical features include growth and psychomotor retardation, microcephaly, convergent strabismus, bulbous nose, long philtrum, short neck and cardiopathy.

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.
