Abstract
Protein restriction during lactation has been suggested to diminish parasympathetic activity, whereas sympathetic activity is enhanced in adult rats. The present study analyses whether dysfunction of the autonomic nervous system is involved in the impairment of insulin secretion from perinatally undernourished rats. Male neonates were reared by mothers fed a low- (4%) protein (LP group) or normal- (23%) protein diet (NP group). At 81 days of age, LP rats showed less body mass than NP rats (318 ± 4 g versus 370 ± 5 g) (P < 0.001). Fat tissue accumulation decreased in LP [0.8 ± 0.03 g/100 g body weight (BW)] compared to NP rats (1.1 ± 0.04 g/100 g BW) (P < 0.001). LP were glucose-intolerant as registered by the area under the curve of an i.v. glucose tolerance test (37 ± 3) compared to NP rats (29 ± 2) (P < 0.05); however, LP animals showed fasting normoglycaemia (LP, 5.0 ± 0.1; NP, 4.9 ± 0.03 mm) and hypoinsulinaemia (LP, 0.10 ± 0.02 ng/ml; NP, 0.17 ± 0.02 ng/ml). LP also showed glucose tissue uptake 60% higher than NP rats (P < 0.05). Vagus firing rate from LP was lower (7.1 ± 0.8 spikes/5 s) than that in NP rats (12.3 ± 0.7 spikes/5 s) (P < 0.001); however, there was no difference in sympathetic nervous activity. The cholinergic insulinotrophic effect was lower in pancreatic islets from LP (0.07 ± 0.01 ng/min/islet) than in NP rats (0.3 ± 0.06 ng/min/islet), whereas the levels of adrenaline-mediated inhibition of glucose-induced insulin release were similar. Perinatal protein restriction inhibited the activity of the vagus nerve, thus reducing the insulinotrophic effect of parasympathetic pathways on pancreatic β-cells, which inhibit insulin secretion.

Abstract
Pleuropulmonary blastoma (PPB) is a rare, aggressive dysontogenetic tumor of childhood. We report the comparative genomic hybridization (CGH) study performed on a case of PPB in a 3-year-old-boy. The tumor was characterized by several chromosomal imbalances. Gains observed affected regions: 1q12-q23, 3q23-qter, 8pter-q24.1, 9p13-q21, 17p12-p11, 17q11-q22, 17q23-q25, 19pter-p11, and 19q11-q13.3. Whole chromosome gains were detected at 2 and 7. Loss of genetic material was found at regions: 6q13-qter, 10pter-p13, 10q22-qter, and 20p13. To our knowledge, there have been no CGH reports on PPB, but it is interesting to note that 1) the alterations found confirm previous cytogenetic reports describing gains of chromosomes 2 and 8 as recurrent abnormalities in this type of tumor, suggesting that a gene or genes of putative relevance in PPB pathogenesis are mapped at 8p11-p12, and 2) the CGH profile of this case is very similar to those observed in embryonal rhabdomyosarcomas, in which gains of 2 or 2q, 7 or 7q, and 8 or 8p and loss of 10q22-qter are consistently found. This finding supports the hypothesis that PPB may be tumorigenetically related with embryonal rhabdomyosarcoma.

Abstract
This is the 11th official document of the SIOP Working Committee on Psychosocial Issues in Pediatric Oncology, instituted in 1991. There is a tendency for some physicians to make blanket statements against the use of non-proven, nonconventional therapies, even when these therapies are not harmful. There is an equal and opposite tendency on the part of many parents to do all that they possibly can for their children, including using any non-conventional therapy they feel might do some good. The health care team must open a healthy dialogue with parents that will lead to a clear distinction between those complementary therapies that are harmful and those that are not, indeed, might even be helpful psychologically if not therapeutically.

Abstract
p73, a recently identified gene showing high homology to p53 and mapping to 1p36.33, was presented as a candidate gene for neuroblastoma. In this study the authors evaluate the levels and allelic nature of p73 expression in primary neuroblastomas using reverse transcription-polymerase chain reaction-restriction fragment length polymorphism strategies based on intragenic polymorphisms. From 32 neuroblastoma patients, 11 were heterozygous for the p73 polymorphisms analyzed. p73 expression was found to be low in the correspondent tumors and while all 6 stages 1 and 2 tumors presented biallelic expression, 4 out of the 5 stage 4 tumors showed only one active p73 allele. Analysis of blood samples from 8 healthy donors and 4 neuroblastoma patients revealed much higher levels of p73 expression, and exclusively of biallelic nature. These results are supportive of a role for p73 in the biology of neuroblastoma, particularly in some advanced tumors. Nevertheless, the G81A/C91T polymorphism, previously implicated in regulating the expression of p73, did not show any significant association with neuroblastoma development.

Abstract
BACKGROUND Spinal cord injury is a possible complication associated with removal of thoracic dumbbell neuroblastomas. Our experience with two children whose postsurgical course was complicated by midthoracic spinal cord ischemia is reported there. Permanent paraplegia resulted in both. PROCEDURE AND RESULTS Preoperative awareness of the origin and distribution of the Adamkiewicz artery (arteria radiculomedullaris magna, ARMM) and of the possible collateral pathways for spinal cord blood supply may be helpful in the planning of operations that involve dissection in the midthoracic posterior mediastinum. Otherwise, a flaccid paraplegia may result. CONCLUSIONS The syndrome is presumed to be triggered by a spasm, an embolism, or a iatrogenic interruption of the ARMM.

Abstract
This, the sixth official document of the SIOP Working Committee on psychosocial issues in pediatric oncology, develops another important and especially difficult topic: assistance for terminally ill children with cancer. This is provided for the pediatric oncology community as a useful set of guidelines. It should be always possible for a declining child to die without unnecessary physical pain, fear, or anxiety. It is essential that he or she receive adequate medical, spiritual, and psychological support, and that the child at no point feels abandoned. Palliative care, in the terminal phase of cancer, should be tailored to the different needs and desires of the child and the family, with the goal of providing the best possible quality of life for the days that remain.

Loss of heterozygosity at chromosome 9p21 in primary neuroblastomas: evidence for two deleted regions. CANCER GENETICS AND CYTOGENETICS 1997; 96:134-9.

Abstract
The genes responsible for the development of neuroblastoma following in vivo deletion or mutation are largely unknown. We have performed loss of heterozygosity studies on a series of 24 Portuguese primary neuroblastomas using 6 polymorphic markers located at chromosome 9p21 spanning the p16/MTS1/CDKN2, p15/MTS2/CDKN2B, and the interferon alpha and beta genes. Loss of heterozygosity was observed in 4 of the 24 tumors (17%), a somewhat lower percentage than a previous study that identified patients by a mass screening program. A correlation was also observed between 9p21 LOH and 1p36 LOH in our group of tumors. Two distinct regions of 9p21 deletion were observed: one located in the region adjacent to the markers D9S162 and D9S1747 and a second located centromerically of the p16 gene near the D9S171 marker. The latter region is exclusive of the p16 gene. This result suggests the presence of at least one other tumor suppressor gene at 9p21, apart from the p16 and p15 genes, which may be of importance to the development of neuroblastoma.

Abstract
During a 30-year period 24 epithelial salivary gland tumors were diagnosed in children and adolescents less than 18 years of age. The cases were retrieved from a series of 759 consecutive cases of salivary gland tumors (3.2%) from the area corresponding to southern Portugal during the same period of time. The mean age of the patients was 13.4 years, and one case was congenital. There was a slight female predominance (male/female ratio 1:1.7). The parotid gland was affected in most cases (70.8%). Seventeen neoplasms were benign, and the remaining seven were malignant. As in the adult group, pleomorphic adenoma was the most frequent benign tumor (66.6%), with similar histologic findings and clinical course. Mucoepidermoid carcinoma was the prevalent malignant tumor (20.8%), had a high grade of differentiation, and had a favorable outcome. The histologic pattern of the congenital neoplasm was similar to that of adult epithelial-myoepithelial carcinoma.

Abstract
Fifty children with Ewing's sarcoma were consecutively treated from 1962 to 1987 and retrospectively analyzed at the I.P.O.F.G. of Lisbon. At first diagnosis, 10 cases had distant metastases. The remaining 40 patients had clinically localized disease, and different protocols were followed over the years. The best results were obtained with chemotherapy and radiotherapy with or without surgery; and for these children the two-year survival rate was 42.8% vs. 8.3% for the group of patients submitted to local treatment alone. Besides the treatment modality, other factors influenced the prognosis, such as inflammatory signs, sex, tumor volume, and tumor site as well as evidence of distant metastases.

Abstract
The problem of Euthanasia is approached in the light of the Hippocratic principles, which have not changed with time but have only been adapted to new scientific and social developments. The definition of what constitutes Euthanasia is clarified and the need to avoid that semantic mutations may manipulate ideas is stressed, so that what is certainly wrong does not seem to appear as right. The uniqueness and individuality of the human being is emphasized as well as the commitment of doctors to their patients wellbeing, although at times a balance may be needed in relation to some apparently conflicting interests of society as a whole. The importance of the doctor/patient relationship is stressed, particularly in the final stages of terminal disease. Decisions concerning life and death, although preferably to be shared, still rest most times upon the doctor's shoulders alone. The respect for the wishes of the patients, their right to know the truth and its limits, the use of the living will, the right to die in dignity, the use of ordinary or extraordinary means of treatment, the concept of brain death and the rules for resuscitation, are commented upon. In all cases, the need for a global and individualized approach is mandatory before any final decision is made. Total respect for human life, from its beginning to its end is emphasized, intentional killing, for whatever reason or motivation, is firmly rejected. Reference is made to national and international codes of ethics as well as to declarations and statements of the World Medical Association.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Fine needle aspiration cytology (FNAC) became increasingly popular for evaluating of both superficial and deep seated lesions, but its use in children has been limited. We report our recent experience with FNAC in the pediatric group. The study population included 34 males and 12 females and the age ranged between 11 months to 16 years. The aspirated sites were: testis (n = 14), lymph node (n = 12), bone (n = 9), pelvis (n = 2), retroperitoneum (n = 1), soft tissue (n = 6), lung (n = 1) and orbit (n = 1). The aims of FNAC were to diagnose a primary lesion (25 cases) and to document relapse of neoplastic disease (21 cases). Of the 46 aspirates, 28 were diagnosed as malignant, 4 as benign, 2 were inconclusive; in the remaining case the material was considered inadequate. Eleven out of 14 testicular cases were normal. FNAC diagnosis was confirmed either by histology (25 cases) or by the clinical evolution (18 cases). We conclude that FNAC can be considered a major diagnostic tool for the characterization of the tumoral lesions in childhood, both for diagnostic purposes and for evaluation of the progression of neoplasia. It may also provide useful information for guiding the therapeutical strategy.
