This quiz came across my feed, thought some of you might like it.

A.     Which of the following is accurate about the presentation of spider bites?
 
1.     The hobo spider (Eratigena agrestis) is especially harmful to humans, with bites that cause necrosis
2.     A wolf spider (family Lycosidae) bite is commonly associated with systemic effects and pain that manifests over a longer duration than most other bites
3.     Jumping spider (family Salticidae) bites are common but usually painless
4.     The most common response to a tarantula (family Theraphosidae) bite is a local histamine response
 
B.     Which of the following is accurate about the presentation of brown recluse (Loxosceles reclusa) bites?
 
1.     Brown recluse envenomation typically elicits immediate intense sensation
2.     Necrosis is more significant in the muscular areas of the arms, legs, and abdomen
3.     Symptoms of systemic loxoscelism are related to the extent of local tissue reaction
4.     A single clear or hemorrhagic vesicle develops at the site after 24-72 hours, which later forms a dark eschar
 
C.     Which of the following statements is accurate about the presentation of widow spider (genus Lactrodectus) bites?
 
1.     Cramping may extend from the local area around the bite to large muscle groups
2.     Hypotension and bradycardia are common after widow spider bites
3.     Systemic symptoms typically begin after 1-2 days
4.     Diaphoresis that occurs remotely from the site of suspected envenomation strongly suggests another cause and not a widow spider bite
 
D.    Which of the following is accurate about the workup of spider bites?
 
1.     Obtaining a glucose-6-phosphate dehydrogenase level may be recommended in patients with brown recluse bites
2.     Patients with widow spider bites may have decreased serum creatinine kinase (CK) levels
3.     Laboratory studies (eg, glycophorin A measurement, complete blood cell count, peripheral white blood cell count) are used to confirm tarantula envenomation
4.     Although funnel-web spider (genera Hadronyche and Atrax) and mouse spider (genus Missulena) bites are often confused, funnel-web spider bites are often confirmed to be "dry" on laboratory findings
 
E.     Which of the following is accurate about the treatment of spider bites?
 
1.     Pressure immobilization dressings are contraindicated in funnel-web spider bites
2.     As a general rule, antivenom should be administered in the field when a significant spider bite is suspected
3.     Hospitalization is generally indicated for patients with a history of hypertension who receive a widow spider bite
4.     Dapsone should be routinely administered to patients receiving brown recluse spider bites

I have such a phobia of spiders that I literally force myself awake when I am dreaming of a spider.

Spider bite on my penis at around age 7 or 8. Looking back on it now I kinda wish the swelling would have been permanent.

They have to push a huge needle into the penis to withdraw the blood when it doesn't go down naturally.

Naw, I got a needle full of steroids in the butt and a nurse assistant doing alternating hot and cold paks on my wiener for about an hour. That may explain some later life behavior.

And that's all I have to say about that.
