Medication and breastfeeding.

It is well accepted that the best feeding method for infants is breastfeeding, due to its numerous biological and clinical effects on child and maternal health. The use of medication by the nursing mother and the physician's advice to stop nursing are the most common reasons for the cessation of breastfeeding. The physician plays an extremely delicate role and should be able to assess risks and benefits for both mother and child. The main factors that must be taken into account include pharmacokinetics, the duration of maternal therapy, the age of the infant and the general health of the infant. All physicians should have access to reliable and updated information on medication safety during breastfeeding (reference books, online medical literature). Few drugs have been demonstrated to be absolutely contraindicated during breastfeeding. Nevertheless clear, safe and reliable information is still lacking for most drugs and it would be desirable to improve the knowledge about mechanisms and consequences of infant exposure to drug present in milk.

Hyperbilirubinemia and management of breastfeeding.

Hyperbilirubinemia and jaundice are natural, physiological phenomena which are only to be expected in the neonatal period, within certain limits. The highest percentage of jaundice in breastfed newborns should be evaluated in connection with inadequate management of breastfeeding rather than a direct effect of breast milk. Breastfeeding is also linked to visible jaundice persisting beyond the first two weeks of life (“breast milk jaundice”), but the appearance of skin jaundice is not a reason for interrupting breastfeeding which can and should continue without any interruption in most cases. There have been numerous contributions to the literature which have rescaled the direct role of breast milk both in early jaundice and in the more severe cases of late jaundice. The reviewed guidelines for detection and management of hyperbilirubinemia underline how prevention of badly managed breastfeeding and early support for the couple mother-child are effective prevention measures against severe early-onset jaundice; furthermore, the breastfeeding interruption is no longer recommended as a diagnostic procedure to identify breast milk jaundice because of its low specificity and the risk to disregarding the detection of a potentially dangerous disease.

Drugs and breastfeeding: instructions for use.

It's universally well known that breastfeeding, due to its numerous beneficial effects on child and maternal health, is the best feeding method for infants. The use of medication by the nursing mother and the physician's advice to stop nursing are the most common reasons for the cessation of breastfeeding. The physician plays an extremely delicate role and should be able to assess risks and benefits for both mother and child. The issue of which drugs are safe to take during lactation is quite complicated. Three main factors must be taken into account: pharmacokinetics, assessment of the risk to the infant and to the lactation. Excellent sources of reliable information are the reference books. For the most up-to-date information it would be useful to consult the online medical literature. Few drugs have been demonstrated to be absolutely contraindicated during breastfeeding. Clear, safe and reliable information is still lacking for most drugs. It would be desirable to see an improvement in knowledge about mechanisms for transfer of drugs into milk, to analyze the biotransformation process for a given drug and to study the clinical consequences of infant exposure to drugs present in milk.

Is breastfeeding duration influenced by maternal attitude and knowledge? A longitudinal study during the first year of life.

OBJECTIVE: To discuss the duration and types of breastfeeding and to identify the factors associated with the early introduction of formula milk. MATERIALS AND METHODS: This longitudinal study was conducted in the largest birthing centre of Turin. 562 mother-infant pairs were selected randomly and enrolled from among all the births that occurred in our Hospital from January to December 2009. Data was collected by means of a questionnaire filled out by the researcher during a face-to-face interview at mother's bed side during her hospital stay. This questionnaire included data regarding maternal socio-demographic, biomedical and hospital-related characteristics and some questions regarding family support, maternal attitude and current knowledge on breastfeeding. Mothers were interviewed by telephone at 1, 3, 6 and 12 months postpartum using the 24-h recall technique and definitions recommended by the WHO to investigate the type of breastfeeding adopted. RESULTS: At the age of 6 months only 8.9% of the infants involved were still exclusively breastfed and 44.3% had discontinued breastfeeding. By the age of 12 months 25.3% of infants were still receiving some breast milk. The main factors that had a negative impact on the duration of breastfeeding included maternal smoking habits, early pacifier introduction and the maternal infant feeding attitude. CONCLUSIONS: The rate of initiation and overall duration of breastfeeding reached the WHO objectives, but exclusive breastfeeding duration has still not reached satisfactory levels at 6 months. Given that the maternal infant feeding attitude is the only factor independently related to breastfeeding duration for the whole first year of life, reliable measures of maternal attitude could be used as a first step in targeting and assessing interventions that promote and sustain breastfeeding.

[Prenatal diagnosis and treatment of congenital toxoplasmosis: a program of regional surveillance]. / Diagnosi prenatale e trattamento della toxoplasmosi congenita: un programma di sorveglianza regionale.

Toxo-net is a regional program of survey on congenital toxoplasmosis which has two aims: 1) to estimate the incidence of gestational and congenital toxoplasmosis in our Region (Piemonte); 2) to assess the compliance to our diagnostic, therapeutic and follow-up protocols which are thoroughly described. Thirty-two obstetrical, neonatal and laboratory units of Piemonte Region have been involved. During 18 months (January 1997-June 1998) 365 pregnant women were studied because of suspected seroconversion: in 129 patients infection was confirmed. Amniocentesis for prenatal diagnosis was carried on 11 patients; two fetuses were affected. 35% of the mothers were untreated or inadequately treated. Hydrocephaly was observed in two fetuses. Neonatal follow-up at 12 months is available for 68 of the 129 infected mothers. Four babies (5.8%) were infected, three of them being symptomatic; their mothers had not been treated. It is concluded that the implementation of a screening program for toxoplasmosis during pregnancy seems to be beneficial. However an effort to improve the surveillance system and the education of the gynecologists, general practitioners and of the patients is needed, and economic evaluations are warranted.

Neonatal drug addiction.

In the twenty years since the first case of neonatal drug addiction (resulting from the mother's use during pregnancy of morphine, heroin, methadone, cocaine) was referred to our attention, there has been a steady increase in the number of cases per year. Heroin alone or in association with methadone now represents the drug used by approximately 80% of addicted mothers. Over the past few years the mean age of mothers has increased; the number of drug users who do not appear to be addicts has also increased and a number of cases have lately been discovered only on the basis of neonatal symptoms, without any previous anamnestic indication. Neonatal abstinence syndrome (NAS) is the most striking effect of fetal exposure to drugs. Symptoms are easily recognised; pharmacological treatment can consist of either sedatives or replacement drugs whose dosage depends on the severity of withdrawal symptoms evaluated using a score system. NAS symptoms are usually resolved within a few days although some signs, especially irritability and tremors, may persist until 3 months of age. The main concern at present regards the future of these neonates. The most severe risk to which they are exposed, after HIV infection, is social; during the past few years in over 50% of cases parental authority has been suspended by the juvenile court. No long-term neurologic or cognitive deficits are directly associated with heroin or methadone use during pregnancy.

Congenital toxoplasmosis: 10-year follow up.

A long-term follow up was begun in 1982 on offspring of mothers who acquired toxoplasmosis during gestation. The 114 newborns were subdivided into 3 groups: (1) 26 born to mothers with certain infection; (2) 51 born to mothers with probable infection, and (3) 37 born to mothers with doubtful infection. There were five infections in the first group (19.2%), three in the second (5.8%) and none in the third. For purposes of data elaboration we considered only the 77 offspring of mothers with certain or probable infection. Of these, 2 infected cases out of 52 (3.8%) were born to mothers with infection in the first trimester of pregnancy, 4 out of 21 (19%) in the second trimester, and two out of four in the third. There were a total of 8 congenital infections (10.4%). Specific IgM antibodies were revealed in five out of eight infected children (62.5%). Infection was symptomatic in two children (2.6% of newborns at risk, 25% of infected cases), both born to mothers with infection in the second trimester. In the other six cases diagnosis was reached by evaluating trends in antibody levels: the percentage of infected newborns was higher in the group of maternal infections untreated (50%) or improperly treated (15.4%), compared to those receiving adequate treatment (6.9%). We suggest considering as infected children presenting specific IgM antibodies and/or antibody titres which do not become negative, even when symptoms are absent. Therapy with spiramycin should be started in all newborns at risk, while the use of sulphamides and pyrimethamine is justified only after the presence of infection is confirmed.(ABSTRACT TRUNCATED AT 250 WORDS)
