The objective of the study was to assess the symptoms and signs of genital irritation produced by different frequencies of nonoxynol-9 (N-9) use. Thirty-five women were randomized to each of 5 groups and used a vaginal suppository for 2 weeks. Group 1: N-9 once every other day; Group 2: N-9 once a day; Group 3: N-9 twice a day; Group 4: N-9 4 times a day; and Group 5: placebo 4 times a day. Study women were examined at admission, one week and 2 weeks with a colposcope for erythema and epithelial disruption, and were interviewed about vaginal itching and burning. The rates of reported symptoms for N-9 users were not significantly different from that of placebo users. The rate of epithelial disruption for women using N-9 every other day was essentially the same as that of women using placebo. The rates of epithelial disruption for women using N-9 1/day and 2/day were 2.5 times greater than that of placebo users. The rate of epithelial disruption for women using N-9 4/day was five times greater than that of placebo users. Genital irritation was located primarily on the vagina or cervix, and vulvitis was not a significant problem. Women who infrequently use N-9 products may not experience an increase in genital irritation. Women who choose to use N-9 frequently may experience an increase in epithelial disruption.

Lectins or agglutinins are proteins with affinity for specific sugar residues. Peanut agglutinin (PNA) and the lectin from the edible mushroom (Agaricus bisporus, ABL) both bind to the disaccharide galactosyl beta-1,3-N-acetyl galactosamine alpha-. This is expressed in keratinocytes as an O-linked chain on CD44, a polymorphic membrane glycoprotein. Many lectins are mitogens and PNA is a mitogen for colonic epithelial cells. However, ABL reversibly inhibits proliferation of colonic cancer cell lines without cytotoxicity and thus has therapeutic potential in situations such as psoriasis where proliferation is increased. We have therefore investigated the effect of ABL on the growth of normal human cultured keratinocytes and a human papilloma virus (HPV)-transformed cell line. In a 5-day dose-response study, keratinocyte growth was greatly reduced by 1.0 microg/mL ABL and completely inhibited by 3.0 microg/mL ABL (ANOVA, P < 0.0001). Exposure to 1.0 microg/mL ABL for only 8 h gave the same growth inhibition as did continued exposure for 3 days. No cytotoxic or morphological changes were observed. An HPV-immortalized cell line was relatively resistant to ABL: in a 5-day dose-response study, exposure to 30 microg/mL was required to inhibit cell growth completely. Topical application of ABL 0.01% or 0.1% to normal human skin caused no change in skin erythema, blood flow or thickness compared with vehicle or baseline (n = 6). ABL 0. 1% in white soft paraffin was compared with vehicle in 11 psoriatic patients, using comparative contralateral plaques. Twice daily application for 2 weeks showed no significant difference from vehicle-treated sites, although the skin thickness of plaques fell from 5.3 +/- 0.4 (n = 11, mean +/- SEM) to 4.1 +/- 0.3 mm. In view of the in vitro results further studies are warranted, particularly if means can be found to improve the epidermal penetration of the relatively large ABL molecule (60 kDa).

The purpose of this placebo-controlled, double-blind study was to determine the safety, tolerability and clinical efficacy of 5-fluorouracil (1%) in a vaginal hydrophilic gel (hydroxyethylcellulose, 1%) to cure intravaginal papillomas in women. Pre-selected, 60 women ranging between 18 and 50 years of age (mean 24.6), having 312 vaginal condylomas (mean 5.2) joined the study. The diagnosis of human papillomavirus (HPV) was established with clinical, histopathological and polymerase chain reaction (PCR) techniques. Subjects were randomized into 2 parallel groups. Each patient was allocated a pre-coded tube 15 g (active or placebo) with graduated vaginal applicators (disposable), and instructions how to insert 4 g of the trial medication deep into the vagina once at bedtime on every other day (1, 3 and 5) per week, to visit the clinic on day 7 for clinical evaluations and to receive the same pre-coded replacement to continue the regimen for another week. A maximum 12 applications were to be used in 4 weeks. Cure was defined as absence of clinical signs of infection, re-confirmed by PCR and Southern blot hybridization negative HPV DNA. By the end of the treatment 48.4% patients and 51.9% lesions were cured. Breaking the code revealed that 5-fluorouracil (1%) gel had cured 83.3% patients and 87% intravaginal warts. Placebo resolved 13.3% patients and 14% condylomas; (active gel versus placebo; P < 0.001). Twelve patients (20%) mostly in the active gel experienced mild erythema, erosion and oedema, with no drop-outs. Among cured patients 3 had a relapse after 16 months. In conclusion, the clinical results of the study demonstrate that 5-fluorouracil (1%) in a vaginal hydrophilic gel is safe, tolerable and significantly more effective than placebo to cure intravaginal warts in women.

This dose-escalation study was performed to evaluate safety and efficacy of imiquimod 5% cream in the treatment of uncircumcised men with penile warts associated with the foreskin. The cream was applied 3 times/week (n=34) or once per day (n=30) over 8+/-2 h. Imiquimod 5% cream was safe in both treatment groups. However, the 3 times/week regimen was better tolerated with a lower incidence of local skin reactions. In both groups, the 2 most frequently reported local skin reactions were erythema and erosion; they were more severe with the once-daily dosing. The most frequently reported application site reactions were burning, pruritus and irritation or pain (once-daily patients only). Total clearance was achieved in 62% of the patients in the 3 times/week group and by 57% in the once-daily group. Thus, imiquimod 5% cream administered 3 times/week was the optimal dosing regimen in the treatment of penile warts in uncircumcised men.

Our objective was to determine the efficacy and safety of imiquimod 5% cream in the treatment of external genital/perianal warts in an open-label Phase IIIB trial. Patients applied imiquimod 5% cream 3 times per week, for up to 16 weeks. Those who cleared their warts were monitored during a 6-month follow-up period. If their warts recurred, or new warts developed during this time, patients could be re-treated for up to 16 additional weeks. Patients who experienced partial clearance during the initial treatment period entered an extended treatment period of up to an additional 16 weeks. A total of 943 patients from 114 clinic sites in 20 countries participated in this study. Complete clinical clearance was observed in 451/943 (47.8%) patients (intent-to-treat (ITT) analysis) during the initial treatment period, with clearance in an additional 52 (5.5%) patients during the extended treatment period beyond 16 weeks. The overall clearance rate for the combined treatment periods was 53.3%. In a treatment failure analysis, the overall clearance rate was 65.5%; a greater proportion of female patients (75.5%) experienced complete clearance than male patients (56.9%). Low recurrence rates, of 8.8% and 23.0%, were observed at the end of the 3- and 6-month follow-up periods, respectively. The sustained clearance rates (patients who cleared during treatment and remained clear at the end of the follow-up period) after 3 and 6 months were 41.6% and 33.0% (ITT analysis), respectively. Local erythema occurred in 67% of patients. In the majority of patients local skin reactions were of mild to moderate severity. In conclusion, imiquimod 5% cream is an effective self-applied treatment for external genital/perianal warts when applied for up to 16 weeks and is well tolerated for up to 32 weeks.

Keratolytic winter erythema is an autosomal dominant skin disorder characterised by erythema, hyperkeratosis, and peeling of the skin of the palms and soles, especially during winter. The keratolytic winter erythema locus has been mapped to human chromosome 8p22-p23. This chromosomal region has also been associated with frequent loss of heterozygosity in different types of cancer. To identify positional candidate genes for keratolytic winter erythema, a BAC contig located between the markers at D8S550 and D8S1695 was constructed and sequenced. It could be extended to D8S1759 by a partially sequenced BAC clone identified by database searches. In the 634 404 bp contig 13 new polymorphic microsatellite loci and 46 single nucleotide and insertion/deletion polymorphisms were identified. Twelve transcripts were identified between D8S550 and D8S1759 by exon trapping, cDNA selection, and sequence analyses. They were localised on the genomic sequence, their exon/intron structure was determined, and their expression analysed by RT-PCR. Only one of the transcripts corresponds to a known gene, encoding B-lymphocyte specific tyrosine kinase, BLK. A putative novel myotubularin-related protein gene (MTMR8), a potential human homologue of the mouse acyl-malonyl condensing enzyme gene (Amac1), and two transcripts showing similarities to the mouse L-threonine 3-dehydrogenase gene and the human SEC oncogene, respectively, were identified. The remaining seven transcripts did not show similarities to known genes. There were no potentially pathogenic mutations identified in any of these transcripts in keratolytic winter erythema patients.

The objective of this study was to analyze the mobilization kinetics of normal (BCR-ABL(neg)) and malignant (BCR-ABL(pos)) progenitor cells using a new, low toxic, out-patient-based mobilization regimen for Philadelphia chromosome-positive (Ph(pos)) chronic myelogenous leukemia (CML) patients. High doses of hydroxyurea (HD-HU, 3.5 g/m(2) per day, orally for 7 days) followed by granulocyte colony-stimulating factor (G-CSF) (10 microg/kg subcutaneously) were administered to 11 newly diagnosed CML patients. Each apheresis product (n = 30) was individually analyzed for the number and genotype of mature colony-forming cells (CFC) and primitive long-term culture initiating cells (LTC-IC), respectively, by reverse transcription polymerase chain reaction (RT-PCR) of individual colonies. Sufficient numbers of CD34(+) cells/kg bodyweight (BW) could easily be obtained in all patients (median, 15 x 10(6)/kg BW per patient) with a median number of three aphereses performed per patient (range 2-4). Almost each apheresis itself (25/30) contained > or =2 x 10(6) CD34(+) cells/kg BW. All patients with low and intermediate Sokal risk indices (9/11) mobilized primarily BCR-ABL(neg) LTC-IC (median 92%, range 47-100) and CFC (median 89%, range 57-100). Moreover, the mean percentage of BCR-ABL(neg) CFC and LTC-IC in the various apheresis products in these patients did not change throughout the entire time of hematopoietic regeneration. The toxicity of the mobilization procedure was low. Side effects were mild erythema in 8/11 and oral mucositis in 3/11 patients. Overall, the low toxicity of this regimen, together with the fact that sufficient BCR-ABL(neg) progenitors can be collected throughout the entire period of hematopoietic regeneration, renders this mobilization regimen particularly attractive for the collection of BCR-ABL(neg) progenitors in early chronic phase of Ph(pos) CML.

Our objective was to determine the optimal duration of treatment with imiquimod for external genital warts over 4, 8, 12 or 16 weeks. A total of 120 women with a history of genital warts for a median of 3-6 months and prior alternative treatments in 73% were evaluated for total clearance rates. There was no statistically significant difference in complete clearance rates after 16-week follow-up across treatment groups: four weeks (40.0%), eight weeks (48.4%), 12 weeks (39.3%) and 16 weeks (51.6%). Imiquimod was well tolerated, and in those treated for four weeks there was a lower incidence of local skin reactions such as erythema and erosion, and no incidences of pain. These preliminary results suggest that a four-week treatment course of imiquimod applied thrice weekly for women with external genital warts may provide a reasonable approach with comparable efficacy and compliance, and minimal adverse events, drug costs and clinic visits.

Recently, a number of medications approved for nondermatologic use have proved useful against dermatologic diseases. This article reviews the dermatologic uses and effects of deferasirox, bortezomib, dasatinib, and cyclosporine eye drops. Deferasirox--an oral iron chelator--could be an effective treatment against porphyria cutanea tarda, hemochromatosis, and pathogens such as mucor that thrive in iron rich environments. Bortezomib, a proteasome inhibitor and multiple myeloma treatment, may be effective against nodular amyloid and has been effectively used against squamous cell carcinoma; although trials demonstrate it is ineffective against metastatic melanoma. Bortezomib has many cutaneous side effects including erythematous plaques or nodules, a generalized morbilliform erythema with ulcerations and fever, purpuric eruptions, leukocytoclastic vasculitis, Sweet's syndrome, and folliculitis. Dasatinib is a multi-targeted tyrosine kinase inhibitor active in vitro against most cell lines containing BCR-ABL mutations that confer resistance to imatinib. Dasatinib is likely to be effective against dermatofibroma sarcoma protuberans and cutaneous acute lymphoblastic leukemia, and has caused panniculitis. Cyclosporine 0.05% ocular emulsion (eye drops) are approved to treat dry eyes including dry eyes caused by collagen vascular disease. Cyclosporine eye drops might also have utility in treating eye pathology of ocular rosacea, atopic keratoconjunctivitis, graft versus host disease, herpes keratitis, chronic sarcoidosis of the conjunctiva, conjunctival manifestations of actinic prurigo, keratitis of keratitis-ichthyosis deafness (KID) syndrome, and lichen planus-related kerato-conjunctivitis. This article speculates that cyclosporine eye drops would also be useful for any disease causing ectropion or eclabion of the eye as well as toxic epidermal necrolysis-related eye pathology (in particular corneal scarring).

How to treat CML patients who are resistant to inhibitors of BCR-ABL tyrosine kinase such as Imatinib is a very important and urgent issue in clinical hematology. Here, we report a case of Imatinib-treated CML in which intradermally administered WT1 peptide vaccine elicited WT1-specific immune responses and the resultant reduction in the persistent residual disease in co-administration of Imatinib. BCR-ABL mRNA levels were being maintained under the detection limit for 8 months since week 77 of vaccination. No adverse effects except local erythema at the injection sites were observed. The tetramer assay revealed that the decrease in BCR-ABL mRNA levels was associated with the increase in frequency of WT1-specific cytotoxic T lymphocytes, notably effector-memory type of that, in the patient's peripheral blood. The case presented here indicates that WT1 peptide vaccine may become a safe and cure-oriented therapy for CML patients who have residual disease regardless of the treatment with Imatinib.
