Acute and recurrent skin ulceration after spider bite.

We reviewed the records of the Australian Venom Research Unit and The Alfred Hospital Department of Hyperbaric Medicine from January 1992 to July 1998 and found 15 cases of skin ulceration after spider bite that could be followed up with the patient and the treating physician. Fourteen patients had skin ulceration attributed to white-tailed spider bites but in only three was this confirmed. One patient had skin necrosis after a confirmed black house spider bite. Recurrent skin ulceration occurred in nine of the 15 patients.

Venomous marine creatures.

BACKGROUND: Many venomous marine creatures inhabit Australian waters, causing significant morbidity and occasional fatalities. No antivenom is available for most of these creatures. Little is known about the venom or syndromes produced by many of these creatures. OBJECTIVE: This article discusses the features of envenomation by some of the more commonly encountered venomous marine creatures, and the recommended first aid and medical management of such envenomations. DISCUSSION: The information contained within this article is intended to provide the reader with an overview of some of the more common marine envenomations, and hopefully with the knowledge to effectively manage such problems.

Spider bite. A rational approach.

BACKGROUND: Spider bite is one of the most common envenomation problems in Australia. Australia is home to two spiders of major medical importance; the Sydney funnel web spider and the redback spider. OBJECTIVE: This paper describes the features of envenomation and discusses treatment for bites by the Sydney funnel web spider and the redback spider. Bites by other spiders are also discussed, as is the problem of necrotising arachnidism. DISCUSSION: It is hoped that the information contained within this article will be of help to medical practitioners dealing with spiderbite throughout Australia. There is, as yet, a great deal to be learned about spiderbite, particularly necrotising arachnidism.

Could this be snakebite?

BACKGROUND: Australian snakes are among the most venomous in the world. Although usually obvious, the occurrence of snakebite is occasionally unrecognised by the patient and/or physician, resulting in delayed or inadequate treatment, or even in death. OBJECTIVE: This article describes the historical, clinical and pathologic features associated with envenomation by various Australian venomous snakes, and discusses the investigation and management (including first aid) of suspected snakebite. DISCUSSION: A high index of suspicion should be maintained, particularly in rural areas and in patients unable to give a history. Investigations including creatine kinase, clotting profile and venom detection kit should be performed in cases of suspected snakebite. The choice of appropriate antivenom and its indications are discussed.

Funnel-web spider (Hadronyche infensa) envenomations in coastal south-east Queensland.

Five patients with confirmed funnel-web spider bites (Hadronyche infensa) presented to Nambour General Hospital, in south-east Queensland, between 1992 and 1998. Two patients required antivenom; low doses of antivenom were effective. Patients were bitten in spring and early summer. In areas such as this, where funnel-web spider bites are reported less frequently than in New South Wales, clinicians and the community should be aware of the risks and immediate management of these bites.
