We describe an 11-year-old girl with a cowpox virus infection, who presented with a 14-day-old crusted, ulcerated nodule on the chin/neck and a 6-day-old eroded blister on the left leg. The girl lived in a rural environment, had close contact to several cats from the neighborhood, and had an atopic predisposition. The presence of orthopox virus in the lesion on the left leg was demonstrated by electron microscopy (negative staining, transmission electron microscopy) and virus isolation. Classification as a cowpox virus was determined by polymerase chain reaction (PCR), followed by restriction enzyme digestion of the PCR product.

Clinical TrialDepigmentation therapy in vitiligo universalis with topical 4-methoxyphenol and the Q-switched ruby laser.
Monobenzylether of hydroquinone is used worldwide to remove residual pigment in patients with vitiligo universalis. Because of the side effects reported with this drug, the use of monobenzylether of hydroquinone has been restricted in The Netherlands. ⋯ Depigmentation therapy using a 4-MP cream and/or QSR laser therapy is an effective and safe method to remove disfiguring residual pigment in patients with vitiligo universalis. Patients should be warned that repigmentation may occur, even after total depigmentation has been achieved.

Scleromyxedema is a rare connective tissue disease of unknown cause characterized by a generalized papular eruption, dermal fibroblast proliferation, and monoclonal paraproteinemia. A paroxysmal triad consisting of high fever, seizures, and coma with a flu-like prodrome can rarely occur in patients with scleromyxedema and is termed "dermato-neuro syndrome." We describe a 41-year-old patient with scleromyxedema in whom the dermato-neuro syndrome developed.

Clinical TrialDepth of cutaneous analgesia after application of a eutectic mixture of the local anesthetics lidocaine and prilocaine (EMLA cream).
EMLA cream, a eutectic mixture of lidocaine and prilocaine, is a topical anesthetic, frequently used to avoid pain during venipuncture and superficial surgery. However, the depth of analgesia needs further exploration. ⋯ Skin biopsy punch insertions in steps of 1 mm appear adequate for assessing the depth of cutaneous analgesia. Biopsy punch insertions with acceptable pain can be made to depths of 1 to 2 mm after 60 minutes, to 2 to 3 mm after 120 minutes, and to 6 mm after 3 to 4 hours of EMLA cream application.
