Scientific Electronic Library Online Spanish. They show normal cell replacements that constitute genuine mistakes of morphogenesis. The absence of regression of these malformations implies that they remain throughout the lifetime. The terminology describing this type of lesions gave rise to confusion in the medical literature until the International Socie mas ty for the Study of Vascular Anomalies adopted a classification based on the dominant vessel of the malformation in This classification distinguishes between simple and complex forms depending on whether they affect one or several types of vessel.

Vascular malformations can show themselves as isolated lesions or can be associated with other lesions, constituting the guide sign or being the principal marker of some syndromic complexes. This paper describes the principal signs and symptoms of those syndromes in which a vascular malformation is the key that raises suspicion about the existence of other associated lesions.

Chronic pesticide exposure is a recognized risk for human health. The frequency of congenital malformations in exposed people, can be used for epidemiological studies assessing reproductive risk secondary to toxic exposure. A prospective study of cases and controls.

The exposure could be caused by occupational activities o mas r residence around fumigated crops. The records of cases and controls from the surveillance carried out in the Hospital Regional de Rancagua were analyzed.

Malfogmaciones hospital is active member of a collaborative study of congenital arterikvenosas in Latin America. In two years there was a total of newborns 18 stillborn with congenital malformations, with an incidence of Considering only children born alive, the paired analysis of cases and controls showed an association of congenital malformations with a history of maternal exposure, with an attributable fraction of These results, showing an association between pesticide exposure and congenital malformations, should be analyzed in the future by a logistic regression test.

Bernal, Jaime; Zarante, ,alformaciones Since the discovery of insulin, the prognosis of pregnancies has improved, both for the mother and the offspring.

However, arteroivenosas prevalence of congenital malformations at birth has not decreased significantly. The embriological process that leads to anomalies in the offspring of diabetic mothers probably occurs between 6 and 8 mas weeks of gestation. According to animal experiments, hyperglycemia, ketones and free radicals may be involved in the genesis of malfomations, but different strains of rats respond differently to these potential teratogenic agents. Possibly, a higher genetic susceptibility towards congenital malformations also plays a role in arterioveenosas women.

Therefore, although peditria intimate mechanism producing malformations in the offspring of diabetic malvormaciones is not known, several strategies to decrease the prevalence of malformations in these women, such as the use of antioxidants, are being tested. The risk of congenital malformations is two to three times higher among women with diabetes mellitus before pregnancy.

Gestacional diabetes is emerging as a risk factor for malformations. Pediatris study the rate and type of congenital malformations among offspring of women with pre-gestational or gestational diabetes.

All births from January through June were investigated. In the study period, 13, births occurred, of which 0. A total of women 2. The prevalence of congenital malformations among offspring of non diabetic women was 7.

The Latin American collaborative study of congenital malformations ECLAMC is a surveillance program designed to monitor the frequency of congenital malformations and detect abrupt changes in their frequency, look for the cause of such change and implement primary prevention measures. To construct a secular trend curve with the frequency of congenital malformations in Chile. Using the ECLAMC protocol, every malformed newborn or stil mas lbirth, weighting more than arteriovenosaw at birth is registered using a standard protocol, and the next non malformed child of the same sex born in the same hospital is assigned as control.


Using the gathered data, secular trend curves of congenital malformations were constructed. Between andthere is a secular tendency in the rate of congenital malformations and maternal age, with a correlation coefficient of 0. Several maternal diseases, such as diabetes mellitus or high blood pressure, are associated with a higher risk for fetal or neonatal problems.

Malformacionrs study the association between chronic diseases of the mother and congenital malformations.

A sample of mothers with a chronic disease was co mas mpared with healthy mothers. The presence of congenital malformations in the newborns was studied. The odds ratio OR of a mother to have a child with a congenital malformation was calculated. Mothers with bronchial asthma, diabetes mellitus, hypertension and hypothyroidism had an OR over pediatrix of having a child with a congenital malformation. No association between malformaciknes obesity and offspring malformations was observed.

Offspring of diabetic mothers had 8. Existen tres tipos de tratamientos disponibles: The manifestations include hemorrhage, seizures, headacheh, but sometimes they are incidentally found during the diagnostic approach of patients with head trauma or chronic headache. There are three different ;ediatria of treatments: The actual role of the endovascular treat mas ment is as an adjuvant therapy before ,alformaciones or radiosurgery just to diminish the nidus size.

The goal of all treatments is complete nidus obliteration without causing a new neurological deficit. There is a lack of evidence, principally from randomized trials, to point out the role of each of the modalities in the treatment of the AVM. In Chile, the rates of central nervous system congenital malformations at birth remain high, when compared with the rest of the world.

To report the rates of central nervous system congenital malformations in Chilean hospitals. Using the ECLAMC protocol, every malformed newborn or stillbirth, weighing more than g at birth is registered using a standard protocol, peediatria the next non malformed child of the same sex born in the same ho mas spital is malfodmaciones as control.

The rates of central nervous system congenital malformations are higher at the University of Chile Clinical Hospital than in the rest of Chilean hospitals or Latin American Hospitals. There are significantly higher rates of anencephalia in Concepcion and spina bifida in Valdivia, Rancagua and Cerebgales.

In the University of Chile Clinical Hospital, global annual rates have a negative slope of From each nest, the total number of eggs and the number of embryos and neonates with any kind of abnormalities were registered. In 21 types of malformations located on seven anatomical regions, three new types were registered: The carapace presented significantly higher frequency of abnormalities The most frecuent type pediaria malformation was the compressed carapace A frequency of malformations of 7.

To report the frequency of digestive system congenital malformations in this population.

Analysis of data from the births that occurred at the University of Chile Hospital, that was gathered using codified form for the Latin Ame mas rican Collaborative Study for Congenital Malformations. Ninety seven digestive congenital malformations were detected, with a rate of Diaphragmatic hernia was the most frequent malformation found, followed by imperforated anus, onphalocele and esophageal atresia.

There was a secular increase in the frequency of these malformations. Anorectal atresia is a relatively frequent malformation in the newborn. To determine the frequency of anorectal malformations at birth, and compare the figures with those of other maternity hospitals in Chile participating in ECLAMC, with the figures of the whole ECLAMC and with figures from other worldwide monitoring syst mas ems.


During the study period, 70, children were born, 4, had a malformation and 54 had an anorectal malformation 7. Fifty nine percent had other associated malformations of the urinary tract in Five stillborn babies had other severe malformations. Twenty one children had a fistula. When compared with normal controls, malformed newborns had a lower birth weight, lower gestational age and a higher mean maternal age, a higher frequency of metrorrhagia during the first trimester of pregnancy, a higher number of siblings with malformations and a higher degree of consanguinity among parents.

The participation of recessive genes in the etiology of anorectal malformations is suggested. Valenzuela, Carlos Y IVF and ICSI are also associated to an increased admission to neonatal intensive care units and more nee mas d for health care resources in infancy.

The causes of these anomalies could be pathological conditions for which ART is applied, a direct effect of technologies on the zygotes or embryos, avoidance for zygotes or embryos of the oviduct path that is needed to elicit necessary immunity or genomic programming processes, or adaptive selective steps acquired during thousands of millions of generations in evolution.

There is an association between extreme maternal ages and the risk of congenital malformations. This is specially true for chromosomal abnormalities among women of advanced ages and disruptive malformation among teenage mothers. To determine the association between maternal ages and incidence of congenital malformations at the obstetric ward of a clinical hospital.

To compare these figures with those of Malforaciones. This is a database of all marformations detected in newborns at the hospital. There is a significantly lower frequency of mothers aged less than 20 years than in the rest of Chile.

MALFORMACIONES (malformations): Topics by

Mothers aged between 20 and 29 years have the lower frequency of malformed children. Maternal ages and the rates of malformations, increased in a parallel fashion at a rate of 0.

Las frecuencias encontradas son similares a las del resto del mundo. Un manejo temprano, adecuado e interdisciplinario es vital para disminuir la discapacidad y mejorar la calidad de vida de estos pacientes.

The frequency of the main congenital malformations were tabulated for major urban centers in Colombia. Data included the age of mother, gestational age, gender and weight of the newborn and the congenital malformation. Cases were classified according to a prognostic scale to assess the impact of health team interventions in the recovery process. Congenital defects were noted in 3. The most frequent congenital defects were those of the ears. Clubfoot, polydactyly and cleft lip or palate were more common amongst males.

The weight and gestational age were lower in the congenitally affected in comparison with the control group. Frequencies of congenital malformations in Colombia were similar to those reported in other countries. The interventions of the health team in treating patients with congenital malformations directly affected patient prognosis.
