Background: Adolescent suicide has become increasingly more prevalent in recent years, with self-poisoning being a frequent means of suicide attempt.

Objective:  To investigate the factors associated with adolescent self-poisoning.

Methods: Data on adolescents referred for intentional self-poisoning to the Adolescent Medical Unit during the years 1990–1998 were evaluated retrospectively. Data were obtained from the hospital medical records and included the following factors: sociodemographic data, educational status, agent and route of intake, motivation for overdose, and the extent of serious suicidal intent.

Results:  We evaluated 324 cases of adolescent self-poisoners aged 12–18 years (mean ± SD 14.8 ± 1.5 years). The female/male ratio was 8:1. Most of the patients were attending school and lived in urban areas. Oral ingestion was the only route of intake; 84.5% of the patients ingested drugs and 10.5% non-medicinal compounds. The drug most commonly taken was acetaminophen. The non-medicinal compounds were mostly pesticides and household materials. The suicide attempts were most frequently associated with transient depression, stemming from defects in child-family communication. As based on clinical psychiatric evaluation, patients who had ingested polydrugs and non-medical compounds evidenced a significantly greater suicidal intent (c² =11.9, P < 0.001) compared to those who took only one or two kinds of drugs.

Conclusions: We found that self-poisoning attempts occur most frequently in depressed females at junior high and high school, usually in the context of family dysfunction.  Non-medicinal agents and polydrug ingestion are major risk factors for evaluating the seriousness of the suicidal intent.

Background: Narcotic abuse has steadily become more prevalent in Israel and may result in an increasing number of children exposed prenatally to narcotics, with a consequent increase in the number of infants born with neonatal abstinence syndrome.

Objective: To report our experience with infants born to narcotic-addicted women between the years 1995 and 1998 at the Soroka University Medical Center.

Methods: The medical records of 24 newborns and their drug-addicted mothers admitted to our Medical Center for parturition were analyzed retrospectively. A diagnosis of NAS was established on the basis of the clinical presentation and anamnesis. The Finnegan Neonatal Abstinence Scoring System was used to assess drug withdrawal. Urine toxicological analysis for narcotics was done only for year 1998.

Results: Of the 24 newborn infants exposed prenatally to narcotics 23 (96%) developed NAS, and 78% (18 of the 23) had a Finnegan score of 8 or more. These 18 infants were treated pharmacologically (tincture of opium and/or Phenobarbital) until the score was reduced to less than 8, after which they received supportive treatment. In one child who became lethargic after the first dose of tincture of opium, the medication was stopped and supportive treatment alone was given. Four of the five neonates with scores of 7 and less were given supportive treatment. One of five infants who had a low Finnegan score at birth nevertheless received pharmacological therapy to prevent further deterioration of his physical state since he was born with severe dyspnea. Ten of the 24 children (42%) were followed for lengths of time ranging from 6 to 22 months after discharge, all of whom showed normal development.

Conclusion: About three-quarters of newborns exhibiting withdrawal syndrome required pharmacological therapy. Previous information on maternal drug abuse is a crucial criterion for early detection and treatment.
 

Background: Childhood poisoning continues to challenge the diagnostic and treatment skills of the pediatrician. Generally, childhood poisoning can be attributed to suboptimal parental supervision and accessibility of products with poisoning potential.

Objective: To evaluate the pattern of acute poisoning in children with relation to different age groupings.

Methods: Pediatric patients hospitalized for acute poisoning at the Soroka Medical Center over a 5 year period (1994-98) were evaluated retrospectively. Special attention was given to poisoning in relation to age groupings.

Results: During the years 1994-98 a total of 1,143 children were admitted for acute poisoning to the Soroka Medical Center. The majority of cases occurred in children aged 2-5 and 14-18 years. Males under 14 had a higher frequency of poisoning, the poisoning usually being unintentional, whereas poisoning in females occurred mostly in the 14-18 age group and was intentional. Drugs were the most common agent of poisoning in infants (0-1 year), in older children (10-13 years), and in adolescents (14-18 years), while in children aged 2-5 and 6-9 years either cleaning products or drugs were the usual agents of poisoning. Most poisonings in children aged 2-13 occurred between 4 and 8 p.m., and for most adolescent patients (14-18 years old) between 4 p.m. and midnight. Poisoning in children aged 2-13 were usually due to accessible home products, and to medicinal errors such as overdose and improper drug administration.

Conclusions: This study defines the characteristic pattern of pediatric poisoning with respect to different age groups and gender. Unintentional childhood poisoning predominated in males and occurred mostly because of accessible home products and suboptimal parental supervision during critical hours of the day. Most adolescent poisoning occurred in females and was intentional. Parental education and intensified child supervision are indicated measures of prevention for unintentional poisoning.

Background: Extensive cleaning of homes in Israel before Passover may result in increased exposure of children to cleaning substances.

Objectives: To evaluate the potential danger of Passover cleaning to children, and to study the risk factors in order to identify areas for prevention.

Methods: All cases of poison exposure in Jewish and Arab children under the age of 15 years reported to the Israel Poison Information Center during 1990–95 (n= 5,583) were analyzed for the 6 weeks before and 6 weeks after Passover. Poison exposures in Jewish children <15 years old were studied in seven pediatric emergency rooms for the 2 weeks before and 6 weeks after Passover (n=123).

Results: The IPIC data showed a highly significant 38% increase in the average weekly poison exposure rate for the 2 weeks before Passover compared with the remaining 10 weeks.  Data recorded by the pediatric emergency rooms showed a twofold increase in cleaning substance poisoning during the 2 weeks before Passover compared with the following 6 weeks. The rise in exposures to cleaning substances was observed among children from secular, religious and ultra-orthodox families. In these exposures, the substance was found in open containers in 70% of cases. 

Conclusions: The extensive cleaning of homes among Jewish families in preparation for Passover poses the danger to young children of cleaning substance poisoning. Increasing public awareness, closer observation of children, and keeping these substances in closed containers should increase children’s safety during this annual cleaning.

Background: Prenatal lead exposure (umbilical cord blood lead concentration 10 (μg/dl) may impair cognitive development. Childhood lead poisoning is infrequent in Israel, and there are no data on lead exposure in immigrants to Israel from the former Soviet Union.

Objectives: To evaluate prenatal blood lead concentrations in Israeli newborns whose mothers were born in Israel and in those whose mothers recently immigrated from Russia, and to compare data of prenatal lead exposure in Israel with those reported from other countries.

Methods: We compared the UCBLC of 35 newborns of new immigrants from Russia with a group of 35 newborns whose mothers were born in Israel. Venous BLC was also measured in 50 mothers. Data are compared with similar reports on prenatal lead exposure internationally.

Results: The UCBLC in all 70 newborns (mean±SD) was 3.53±1.6 μg/dl, and mothers' BLC (mean±SD) was 3.90±1.39 μg/dl. UCBLC and BLC in the 50 mother-newborn pairs correlated (γ=0.36, P<0.01). All newborns except one had UCBLC<8.0 μg/dl. There was no significant difference between UCBLC in the two groups.

Conclusions: Prenatal lead exposure among the study subjects in both groups was low. In this sample the newborns of mothers born in Israel and those whose mothers recently immigrated from Russia were not found to be at risk for lead poisoning. Prenatal lead exposure in this sample was low compared to that reported from various parts of the world.
