“…2,3 No patient in our series developed pulmonary edema, shock, evidence of myocardial damage, or death. This series clearly shows that in the great majority of cases, scorpion sting syndrome pursues a benign course and can be safely treated with supportive measures without the use of antivenin.…”

Scorpion Sting Syndrome — A Ten Year Experience

A 10-year retrospective review was undertaken of patients presenting with "scorpion sting" to the Emergency Department of the King Fahad National Guard Hospital in Riyadh. The purpose of the study was 1) to assess the risk of morbidity and mortality following scorpion envenomation in the Riyadh area; 2) to define patient demographics of the study group and identify high risk groups for systemic toxicity; 3) to develop guidelines for patient management. Four hundred and thirty-four cases were studied. Local pain was the primary presenting complaint (92%). Systemic toxicity occurred in 25.6% (n=111). Anxiety-related presentations were the most common systemic symptoms (6%). Hypertension (17%) and/or tachycardia (4%) were the most common systemic signs. Only four patients (<1%) had signs of serious envenomation requiring admission. There were no deaths. The higher risk groups for systemic toxicity were identified as those with age less than eight years or greater than 30 years, with highest risk in those over 50 years, those with history of hypertension or diabetes, and patients with multiple stings. The great majority of patients can be treated with analgesia, local application of ice, and a period of observation dictated by clinical findings. The use of antivenin should be restricted to patients with signs of serious systemic toxicity only. Ann Saudi Med 1995;15(2):148-155.

“…23,24 However, with the exception of transient hypocalcemia, El-Amin (in a study of 96 children admitted with scorpion stings) found no significant hematological or biochemical findings. 2 The clinical presentation of scorpion stings covers a broad spectrum. The vast majority of patients experience no more than localized pain.…”

“…This finding is in agreement with the results of some investigations in other regions of Saudi Arabia, 5,9 ' 10 but not with others that reported deaths following scorpion stings in some areas of the Kingdom. 3,[11][12][13][14][15] Some studies reported that the mortality rate due to scorpion stings in Saudi Arabia was 3% between 1985 and 1993, 10,16 but was less than 0.05% in 1997. 3 Similar studies in Jordan and Morocco have shown a high rate of scorpion sting envenomation with several deaths.…”

BACKGROUND:Information on scorpion stings is available for many parts of Saudi Arabia, but not for Al-Jouf Province. METHODS: We reviewed and analyzed 1449 cases of scorpion stings that presented to the emergency department of the hospitals and medical centers in Al-Jouf Province during a 2-year period (2005)(2006). RESULTS: The majority of patients (92.7%) manifested class I envenomation with local pain at the sting site as the primary complaint. Systemic toxicity was noticed in 7.3% of cases but no deaths were reported. Scorpion stings were recorded throughout the year with the highest seasonal incidence in the summer (64.3%) and the lowest during the winter (10.6%). The highest monthly incidence was in June (21.5%) and the lowest in December (1.5%). Most of the patients were male (77.3%) and the age of 44.2% of victims ranged between 15 to 30 years. Diurnal stings exceeded the nocturnal ones with a ratio of 3:2, and most of the stings were located mainly on the exposed limbs (88.6%), especially the lower limbs (51.7%). Leiurus quinquestriatus and Androctonus crassi-cauda were incriminated in most recorded cases. CONCLUSIONS: Our findings indicate that scorpion stings are common in Al-Jouf Province, especially during the summer. The overall threat to human health was found to be low. Scorpion sting syndrome is a medical problem that represents a real threat in many parts of the world including Saudi Arabia. [1][2][3][4][5] Annually, thousands are stung by scorpions in Saudi Arabia with an average of 14 500 stings per year. 3 While considerable information is available about scorpion sting syndrome in most districts of Saudi Arabia, little is known about scorponism in Al-Jouf province. 4 The present study aims to assess the risk of scorpion stings together with the efficacy of scorpion antivenom therapy, and to clarify the epidemiological features of scorpion stings in this province. METHODSThis study was based on 1449 cases of scorpion stings submitted to the emergency department at the hospitals and medical centers of cities and towns of Al-Jouf province, Saudi Arabia (Skaka, Domat Al-Jandal, Tabarjal and Qorayat) (latitude, 29°47 N, longitude 40°06 W) over a period of 2 years ( January 2005-December 2006). The victims belonged to ten nationalities (Saudi and non-Saudi). The data were extracted from the victim records and analyzed by age, sex, time of sting and submission (month and time of day), sting location on body, scorpion species, presenting complaint, systemic symptoms, received treatment, period of observation and outcome of each sting. The clinical severity of each case was assessed according to Abroug's classification,6 where the envenomation cases were sorted into class I: local symptoms at the site of sting; class II (symptomatic): thrill, sedation, nausea, vomiting, diarrhea and hypertension; class III (systemic): cardiovascular, respiratory, and/or neurological disorders. RESULTSThe total number of scorpion stings reviewed in Al-Jouf province over the period (2005)(2006) was 1449 ( Table 1). T...

ABSTRACT:The venom apparatus of the black scorpion Androctonus crassicauda has been characterized histologically and histochemically in the present study. The results showed that this apparatus consists of paired venom glands, each of which initially presents its own canal and posteriorily both fuse into a single common one.Each gland is covered by a sheath of striated muscle and is lined with extensively folded secretory epithelium (formed of non-secretory and secretory venom-producing cells). The outcomes also revealed that the venom-producing cells of both glands produce neutral mucosubstances, sialomucins, sulfomucins and proteins, but are devoid of glycogen. Cysteine, tyrosine, tryptophan and arginine were also detected along with activities of acid and alkaline phosphatases, mitochondrial adenosine triphosphatase, aminopeptidase, cholinesterase and non-specific esterases.Structure and secretion of scorpion venom glands are discussed within the context of the present results.
