Epidemiological profile of snakebites in Morocco

The present work aims to find the epidemiological profile of snakebites in Morocco through a retrospective study of 1,423 snakebite cases that occurred between 1992 and 2007. Data were obtained from medical charts of envenomation at the Poison Control and Pharmacovigilance Center of Morocco. Results revealed that 86 percent of the snakebites had occurred in rural areas and that males were significantly more affected than females at a sex ratio of 23:20. Furthermore, 35 percent of the bites happened during the summer, with a peak of 215 cases in June (15.1 percent). We also discovered that 67.3 percent of the patients were bitten during the day. The age group that comprised the most agriculturally active persons, from 20 to 44 years old, was the most affected by snakebites (551 cases). In terms of evolution, patients who were at least 60 years of age (8.89 percent) as well as those who were less than 10 years old (7.50 percent) presented higher mortality. According to clinical severity grades, the data revealed a 70 percent predominance of grade 2 cases (430). Deaths had occurred only in patients with grades 3 and 4. Furthermore, grade 4 patients presented 100 percent mortality whereas grade 3 registered 10.7 percent. The distribution of snakebites according to administrative regions in Morocco showed a predominance of the Souss-Massa-Daraa region both in terms of frequency (32 percent) and mortality (72.1 percent). Our study clearly displayed the severity and extent of the snakebite problem in the country, thus revealing that public health authorities should give more attention to this serious situation.(AU)

Epidemiological and clinical characteristics of scorpion stings in children in Fez, Morocco

Scorpion stings are a public health problem in Morocco, especially among children, who experience the most severe cases. Epidemiological and clinical findings on scorpion stings in Fez, Morocco, were evaluated in this investigation. Of 163 cases that required medical attention, 62.6 percent were male children. The mean age of patients was 4.8 ± 3.4 years. The mean time between stings and first medical attention was 3.36 ± 2.5 hours. Almost all cases occurred in the summer (94 percent) and extremities represented the most frequent sting sites (86.5 percent). Local pain, hyperemia, scarification, vomiting, sweating, restlessness, tachycardia and tachypnea were the observed clinical symptoms. Regarding severity, 55.2 percent of patients belonged to class III, followed by class II (26.4 percent) and class I (18.4 percent). None of our patients received antivenom; however, all of them were treated symptomatically depending on clinical manifestations.(AU)

Risk factors caused by scorpion stings and envenomations in the province of Kelâa Des Sraghna (Morocco)

The present study aims to elucidate the risk factors involved in deaths caused by scorpion envenomation. A retrospective study was carried out in the province of Kelâa des Sraghna from 2003 to 2004. The hospital charts of scorpion envenomation cases treated in the Essalama Hospital in Kelâa des Sraghna were exhaustively analyzed. Our study contains 31 cases of death among 470 hospitalization cases. Most stings had occurred during the hot period peaking in July and August (54.6%). Moreover, the scorpion stings occurred at night in 60.1% of the cases, between 6:00 pm and 6:00 am. In addition, all age groups were affected by envenomation, with a higher frequency in children aged less than 15 years (68.3%). The envenomation rate (class II + class III) was 70.9%. The statistical analysis of the data shows that being less than 15 years old, having been stung during the night and belonging to class III are risk factors that aggravate vital prognosis of hospitalized patients. Furthermore, clinical severity factors, elicited by relative risk analysis, are cardiovascular, respiratory and neurological vital distresses, with relative risks of 14.84, 11.92 and 48.33, respectively. The results of our study clearly displayed the severity and extent of the scorpion envenomation problem. Thus, great attention must be paid to this region of Morocco by the national health authorities.(AU)

Scorpion sting: a public health problem in El Kelaa des Sraghna (Morocco)

The present study aimed at verifying the impact of a Moroccan strategy against scorpion stings and specifically at identifying the epidemiological features of patients envenomed or just stung by scorpions. It included 11,907 patients from El Kelaa des Sraghna Province, Morocco, who were evaluated over five years (2001-2005). Most stings occurred during the hot period and mainly at night. The average incidence was 3.2 per 1,000 inhabitants; patients <15 years accounted for 34 percent, and the envenomation rate was 12 percent. Average lethality rate was 0.7 percent. Our work evaluated the efficacy of the adopted strategy based on indicators of follow-up, morbidity and lethality due to scorpion sting and envenomation.(AU)

Scorpion stings in one province of Morocco: epidemiological, clinical and prognosis aspects

The present study aimed at verifying the impact of a Moroccan strategy against scorpion stings and, specifically, at identifying the epidemiological features of the patients envenomed or just stung by scorpions. The investigation included 4089 patients from a province of Morocco which were evaluated over three years (2001, 2002 and 2003). Most stings occurred during the hot period and mainly at night (between 6:00 p.m. and 12:00 p.m.). The average incidence was 2.8‰, the average age of the patients was 26.7±18.2 years, and the envenomation rate was 6.7%. Mortality rate was 0.05‰, and average lethality rate was 0.7%. Analysis of variance showed that young age, symptoms at admission, and long time elapsed between sting and admission were correlated with poor outcome. Comparison among data of the three years revealed an increasing number of reported cases and decreasing morbidity and mortality.
