[Epidemiological data on scorpion envenomation in Algeria]. / Données épidémiologiques sur l'envenimation scorpionique en Algérie.

The scorpion envenomation is a major public health problem in Algeria. Given this fact, the Ministry of Health has developed a national strategy for prevention and control based on the training of health personnel, information, education and communication, and standardization of care on the basis of a therapeutic consensus. The monitoring and evaluation activities are carried out by epidemiological indicators through the implementation of an information system based in the services of Epidemiology, INSP (National Institute of Public Health) and Prevention Department of the Health Ministry. The information carriers are report cards implemented in different health facilities that collect data on bites and deaths from scorpion envenomation. Summaries of notifications from the wilayas are collected monthly, and processed by the Epi info software using monitoring indicators. From 1991 to 2010, there has been a stagnation in the number of stings with an average of 50,000 cases per year, but mortality decreased from more than 100 deaths in the last fifty years to 50 nowadays. The higher proportion of stings was recorded during the summer period. The most affected group is from 15 to 49 years which constitute the workforce, but children from 5 to 14 years rank first in terms of mortality. But these rates vary across years and regions. Despite all these efforts, the scorpion envenomation in Algeria remains of concern and our main challenges are to strengthen cross-sectional actions at the local level and improving the quality of care.

Incidence and severity of scorpion stings in Algeria

Scorpion stings are a public health problem in the Maghreb region. In Algeria, epidemiological data were collected over the past twenty years by the Algerian health authorities. This study is an analysis of morbidity and mortality data collected from 2001 to 2010. Annual incidence and mortality due to scorpion envenoming were 152 ± 3.6 stings and 0.236 ± 0.041 deaths per 100,000 people (95% CI), respectively. The risk of being stung by a scorpion was dramatically higher in southern areas and central highlands due to environmental conditions. Incidence of envenoming was especially higher in the adult population, and among young males. In contrast, mortality was significantly higher among children under 15 years, particularly ages 1-4. Upper limbs were more often affected than lower limbs. Most stings occurred at night, indoors and during the summer. Data collected since 2001 showed a reduction of mortality by nearly 50%, suggesting that the medical care defined by the national anti-scorpion project is bearing fruit.(AU)

[Evaluation of 1st semester activity of the Algiers Poison Center]. / Bilan du 1 er semestre d'activité du Centre Anti-Poisons d'Alger.

The Poisons Center located in Bab el Oued University Hospital of Algiers has been opened to the public since January 2, 1991. The staff is made of public health physicians and pharmacists residents trained in toxicology. Phone calls are a new means for obtaining advice on poisonings and the public must be informed on the modalities of use. The number of calls shows that people are willing to use this fast and effective medium. A specific data sheet was created. The analysis of calls includes the origin of call, the nature of products used, the age range the clinical condition of patients, the recommended treatment and the outcome when known.

[Oral administration effects, with different doses, of arginine aspartate and arginine chlorhydrate upon growth hormone and free fatty acids plasmatic rates in normal fasting children (author's transl)]. / Effets de l'administration "Per Os", à doses variables, d'aspartate d'arginine et de chlorhydrate d'arginine sur les taux d'hormone de croissance et d'acides gras libres du plasma chez l'enfant normal à jeun.

With an equivalent arginine base furniture, arginine chlorhydrate (CA) and arginine aspartate (AA) are orally administered, with variable doses, to normal fasting children, to study during 4 hours evolution of plasmatic growth hormone rates (stimulation of endogenous GH secretion) and plasmatic free fatty acids rates (secondary effects on effectors). With CA 5 g (half dose) opr 10 g (total dose, about 500 mg/kg) mean plasmatic GH rates increase is etale and non significant, when compared to normals. With AA 7,35 g (half dose) or 14,70 g (total dose), there is a 2 h GH peak, when compared to initial values and 2 h normal values (p less than 0,05 or p less than 0.01). Area increases with the two doses AA, when compared to normals (p less than 0,01). With the two products, mean 1 h plasmatic FFA rate does not vary or non significantly decreases. 4 h rate increases, when compared to normals, with CA and AA half dose (p less than 0,05) and CA and AA total dose (p less than 0,01).
