A case of dermal mucinosis and musculoskeletal symptoms simulating polymyositis as a presenting sign of hypothyroidism is presented. The patient presented muscle weakness and edema of the face including the eyelids. Laboratory examination revealed elevated creatinine phosphokinase, decreased free-T4, decreased free-T3, elevated TSH, positive anti-microsome antibody and positive anti-TSH receptor antibody. The skin biopsy specimen revealed swelling of the collagen bundles with the bundles splitting up into individual fibers, with some blue threads and granules of mucin interspersed. Alucian blue stain demonstrated vast amounts of mucin throughout the whole dermis, which was completely removed on incubation with Streptomyces hyaluronidase. The patient was diagnosed as having hypothyroidism due to Hashimoto's disease with possible polymyositis complications. After two months of thyroid hormone replacement therapy, she was euthyroidic and discharged. These results indicate that our case was a rare case of severe generalized myxoedema due to hypothyroidism of Hashimoto's disease simulating the musculoskeletal symptoms of polymyositis.

Human envenomations by Heloderma species are a rare but clinically important medical problem. We report a case of an adult male bitten on the left hand by a 50-cm male, captive specimen of Heloderma suspectum (Gila monster). Immediate signs and symptoms included pain at the bite site radiating into the arm and axilla and swelling of the hand and forearm. Systemic complaints of nausea, diaphoresis, and dizziness (without a decrease in blood pressure) lasted approximately 1 hour, and laboratory studies were normal. The patient's course was uneventful except for persistent hyperesthesia, which eventually abated. Two types of helodermatid bites produce distinct clinical pictures. The chewing bite potentially causes more envenomation than the slashing bite. The venom contains a number of protein and nonprotein components including serotonin, a bradykinin-releasing substance, protease, hyaluronidase, helodermin, and gilatoxin. The clinical presentation of a helodermatid bite can include pain, edema, hypotension, nausea, vomiting, weakness, and diaphoresis. No antivenin is commercially available. Treatment is supportive, and although first aid measures such as suction or compression may impede venom movement, they are unproved. Cryotherapy, tourniquet, and excision are dangerous and should not be used.

Caudal epidural injection (CEI) is one of the most common treatments for low-back pain with sciatica. CEI rarely leads to neurologic complications. We report a case of persistent cauda equina syndrome after CEI. A 44-year-old male patient with severe L4 and L5 spinal ste-nosis underwent CEI for low-back pain and sciatica. The CEI solution consisted of bupivacaine, hyaluronidase, triamcinolone acetonide, and normal saline. He experienced motor weakness and sensory loss in both lower extremities and neurogenic bladder for more than 1 year after the procedure. His ankle dorsiflexors, big-toe extensors, and ankle plantar flexors on both sides were checked and categorized as motor-power Medical Research Council grade 0. His bilateral ankle-jerk reflection was absent. An electrophysiological study showed lumbosacral polyradiculopathy affecting both sides of the L5 and S1 nerve roots. A urodynamic study revealed hypoactive neurogenic bladder affecting both sacral roots.
