Basal cell carcinoma (BCC) is one of the most common cancers. Surgical extirpation is currently the standard of care for BCC, which is associated with several advantages and disadvantages. Procedures such as surgical excision used to treat superficial BCC (sBCC) and nodular BCC (nBCC) may have high 5-year recurrence rates if tumors are not completely excised. ⋯ Pharmacologic interventions provide another treatment option as adjunctive or monotherapy. Investigations of imiquimod, a novel immune response modifier, have indicated that this topical, noninvasive agent is safe and well tolerated and may be efficacious in the treatment of BCC. This review will highlight the role of standard treatment modalities and introduce new advances in the treatment of BCC.

Randomized Controlled Trial Multicenter Study
Safety of efalizumab in adults with chronic moderate to severe plaque psoriasis: a phase IIIb, randomized, controlled trial.
To provide safety data for efalizumab, a recombinant humanized monoclonal IgG(1) antibody, in adults with chronic plaque psoriasis. ⋯ Efalizumab treatment SC for 12 weeks was safe, well tolerated, and effective in patients with moderate to severe chronic plaque psoriasis.

Although head lice, Pediculus humanus capitis, are globally prevalent blood-sucking ectoparasites, the amount of blood imbibed by head lice has not been determined. This study investigated this parameter, as regular loss of a small quantity of blood may lead to an iron deficiency and anaemia. Adult female lice (66), adult males (46), and nymphs (152) were weighed before and after feeding in groups of 17-109 lice. ⋯ The most heavily infected child observed with 2657 lice could be expected to loose 0.7 ml/day or 20.8 ml/month, which may be of clinical importance in a child on an adequate diet, and would be significant in an iron-deficient child. However, if head lice feed more often than three times a day, a heavy infestation would have a greater potential to lead to iron deficiency. The frequency of feeding of head lice on the head of the human host needs to be determined.

Although genital ulceration with or without scar formation is an important manifestation of Behçet's syndrome, formal data on the rate of genital scarring are lacking. ⋯ Two hundred and ten genital ulcers were followed in both sexes. The rate of scar formation was 66.2% (102/154) in male patients and 60.7% (34/56) in female patients. When genital ulcers were stratified as a function of size, large genital ulcers (> or = 1 cm in diameter) developed scars more frequently than did smaller ulcers (< 1 cm). The rate of scar formation in male patients with large genital ulcers was 89.4% (59/66) and with small ulcers was 48.9% (43/88) (P < 0.001). In females, all 19 large ulcers healed with scarring, and the same was true for 40.5% (15/37) of the small ulcers (chi(2) = 18.61, P < 0.001). CONCLUSION About two-thirds of genital ulcers in Behçet's syndrome leave scars. The rate of scar formation depends on the ulcer size.
