Mycosis fungoides is a T-cell lymphoma that arises in the skin and progresses at highly variable rates. Nonradomized studies have suggested that early aggressive therapy may improve the prognosis in this usually fatal disease. We studied 103 patients with mycosis fungoides, who, after complete staging, were randomly assigned to receive either combination therapy, consisting of 3000 cGy of electron-beam radiation to the skin combined with parenteral chemotherapy with cyclophosphamide, doxorubicin, etoposide, and vincristine (n = 52) or sequential topical treatment (n = 51). The prognostic factors were well balanced in the two groups. Combined therapy produced considerable toxicity: 12 patients required hospitalization for fever and transient neutropenia, 5 had congestive heart failure, and 2 were later found to have acute nonlymphocytic leukemia. Patients receiving combined therapy had a significantly higher rate of complete response, documented by biopsy, than patients receiving conservative therapy (38 percent vs. 18 percent; P = 0.032). After a median follow-up of 75 months, however, there was no significant difference between the treatment groups in disease-free or overall survival. We conclude that early aggressive therapy with radiation and chemotherapy does not improve the prognosis for patients with mycosis fungoides as compared with conservative treatment beginning with sequential topical therapies. Twelve patients with early mycosis fungoides were enrolled in a randomized, double-blind, placebo-controlled study. Isolated plaques were injected three times a week with recombinant alpha 2-interferon in nine patients and with the vehicle in three patients. Two additional plaques were evaluated in each patient; one was left untreated, and another was treated topically with either placebo ointment or betamethasone ointment. Biopsies were taken from an untreated, representative plaque prior to treatment and from all test sites following treatment for light microscopy and T lymphocyte subsets. Three of the nine lesions injected with interferon cleared, and all showed improvement. Thirteen of eighteen noninjected lesions improved in patients who received interferon, showing a systemic effect. In the control group, none of the injected lesions improved and only two of the noninjected lesions showed any change. Histopathologic changes confirmed the clinical impression. This study shows that intralesional interferon may be given safely and has a beneficial effect, both locally and systemically. Sixteen patients with mycosis fungoides (MF) were given either active transfer factor (TF) or heat-inactivated TF as additional therapy to topical nitrogen mustard or PUVA. The TF was prepared from non-selected healthy blood donors. The clinical evaluation after 2 years of therapy showed that among 8 patients treated with active TF, none went into complete remission of their disease 4 patients had partial remission, one was unchanged, 2 progressed, and one died of active MF. In the placebo-treated group, 5 patients achieved complete remission and 2 partial remission. One patient died early in the trial due to cardiac disease. Immunological studies during the first year of therapy revealed cutaneous anergy towards tuberculin in most patients. This anergy did not change during TF therapy and differed from normal lymphocyte reactivity in vitro after tuberculin stimulation. At the start of treatment the patients had diminished levels of T lymphocytes in peripheral blood. A temporary increase was observed in the total number of T lymphocytes in patients after one month of treatment with active TF. After one year the T lymphopenia had disappeared in both groups. The mitogen reactivity of lymphocytes was found to be normal (PHA, PWM) or somewhat reduced (Con A). It is concluded that under the conditions employed in this trial, TF was not able to prevent progression of early mycosis fungoides, when viewed over a period of 2 years. A two-part clinical trial was conducted to determine the therapeutic efficacy of recombinant interferon alfa-2b in plaque-phase mycosis fungoides. In an initial randomized double-blind study, each of six patients had two representative plaques injected intralesionally with 1 X 10(6) U of recombinant interferon alfa-2b per site and two control plaques injected with placebo three times weekly for four consecutive weeks. Complete clinical regression of disease was observed at ten of 12 recombinant interferon alfa-2b sites compared with one of 12 placebo-treated sites four weeks after treatment with injections was stopped. Subsequently, in an open-labeled study, five of these patients were treated intramuscularly with 5 X 10(6) U of recombinant interferon alfa-2b three times weekly for four weeks and two patients were treated with a second, more extended course of therapy lasting 12 to 16 weeks. Three of the five patients treated systemically showed some improvement overall, but the responses were judged not to be clinically significant. The differential response observed from intralesional and intramuscular injections may be related to differences in concentration of recombinant interferon alfa-2b achieved in lesional skin by the two methods of administration. An open-labeled, randomized clinical trial to evaluate the efficacy of paromomycin ointment as compared with ketoconazole was conducted on seventy-two patients of both sexes and different ages with the confirmed diagnosis of cutaneous leishmaniasis (CL). All patients had a complete clinical evaluation for other diseases. Patients were excluded if they were pregnant or nursing or if they had serious concomitant diseases. Patients were divided randomly into two treatment groups: in the first group 40 patients were treated with an ointment containing 15% paromomycin sulfate and 12% methylbenzothonium chloride in white soft paraffin (labeled as p-ointment by El-On1) twice daily for 15 days. Treated lesions were left uncovered. The second group consisted of 32 patients who received ketoconazole 400 mg/day orally for 30 days. This dosage was reduced to 200 mg/day for patients below 12 years of age. In all cases the diagnosis was based on positive smear and/or culture. Direct smears were prepared from the exudate obtained by a small incision made at the edge of the lesion with a sterile surgical blade or lancet and stained using the Giemsa method for leishmania bodies (Fig 1). In smear negative and suspected cases aspirates taken by puncturing the lesions were inoculated onto NNN (Novy, McNeal, Nicolle) medium for culture. The cultures were incubated at 28 degrees C and the development of motile promastigotes was observed. Clinical and parasitological evaluations of the patients were performed at the end of the treatment period and 4 weeks post-treatment. A cure was defined as complete healing and disappearance of the lesion or reversible hypopigmentation at the site of lesion. Incomplete or partial improvement was defined as a reduction in the size of a lesion and the absence of parasites on smear or culture. A treatment failure was defined as the absence of any changes in the lesion and persistence of parasites on smear or culture. Hypericin is a known photodynamic agent that has been demonstrated to induce apoptosis in normal and malignant B and T lymphocytes, and has potential to treat benign and malignant disorders of the skin, including psoriasis and cutaneous T-cell lymphoma.
                We wished to test whether topical hypericin was an effective, safe, and well-tolerated therapy for patch or plaque phase mycosis fungoides and for plaque psoriasis.
                We conducted a phase II placebo-controlled clinical study in patients who had either patch or plaque phase mycosis fungoides or plaque type psoriasis vulgaris. Representative lesions were treated twice weekly for 6 weeks with topically applied hypericin or placebo followed 24 hours later by exposure to visible light at 8 to 20 J/cm(2).
                After 6 weeks of twice-weekly therapy, several concentrations of hypericin resulted in the significant improvement of treated skin lesions among the majority of patients with cutaneous T-cell lymphoma and psoriasis whereas the placebo vehicle was ineffective.
                The clinical trial involved a small number of patients.
                Overall, the data from this study support the conclusion that topical hypericin/visible light photodynamic therapy is an effective and well-tolerated alternative to standard psoralen plus ultraviolet A treatment of these disorders.

The aim of this study was to evaluate the safety, tolerability and efficacy of a topical gel containing histamine dihydrochloride (HDC) versus a placebo gel in preventing oral mucositis in hematopoietic stem cell transplantation (HSCT) patients. A total of 45 patients post-HSCT were enrolled in a prospective longitudinal, placebo-controlled, double-blind study. Patients were evaluated twice weekly for oral mucositis (OMAS, NCI score), oral pain (VAS), oral function and salivary flow rate. Compliance was assessed using a patient diary. Oral mucositis developed in 85% of the HDC group and 63% of the placebo group. The mean maximal intensity for NCI score was 1.45+/-1 in the HDC group and 1.21+/-1.27 in the placebo group (P=0.37). The mean duration of oral mucositis was 4.7+/-3.6 and 2.33+/-2.23 days in the HDC and placebo groups, respectively (P=0.06). The same trends were measured with OMAS. Visual analogue scale for oral pain and oral function was not significantly different between the two groups. Histamine dihydrochloride was found to be safe. In the search for topical agents for the prevention of mucositis, we found that HDC neither improves nor worsens oral mucositis in HSCT patients. The balance between the pro- and anti-inflammatory effects of HDC should be investigated further in order to acquire a clinically effective topical medication based on its anti-inflammatory properties. BACKGROUND Tinea pedis (athlete's foot) is the most common fungal infection in the general population. Ciclopirox, a broad-spectrum hydroxypyridone antifungal, has proven efficacy against the organisms commonly implicated in tinea pedis; Trichophyton rubrum, T.mentagrophytes and Epidermophyton floccosum.
                Two multicenter, double-blind, clinical studies compared the efficacy and safety of ciclopirox gel with that of its vehicle base in subjects with moderate interdigital tinea pedis with or without plantar involvement.
                Three hundred and seventy-four subjects were enrolled and randomized to one of two treatment groups: ciclopirox gel 0.77%, or ciclopirox gel vehicle, applied twice daily for 28 days, with a final visit up to day 50. The primary efficacy variable was Treatment Success defined as combined mycological cure and clinical improvement >/= 75%. Secondary measures of effectiveness were Global Clinical Response, Sign and Symptom Severity Scores, Mycological Evaluation (KOH examination and final culture result), Mycological Cure (negative KOH and negative final culture results) and Treatment Cure (combined clinical and mycological cure).
                At endpoint (final post-baseline visit), 60% of the ciclopirox subjects achieved treatment success compared to 6% of the vehicle subjects. At the same time point, 66% of ciclopirox subjects compared with 19% of vehicle subjects were either cleared or had excellent improvement. Pooled data showed that 85% of ciclopirox subjects were mycologically cured, compared to only 16% of vehicle subjects at day 43, 2 weeks post-treatment.
                Ciclopirox gel 0.77% applied twice daily for 4 weeks is an effective treatment of moderate interdigital tinea pedis due to T. rubrum, T. mentagrophytes and E. floccosum and is associated with a low incidence of minor adverse effects. Onychomycosis is one of the most common causes of nail disease and one of the hardest to treat among fungal infections. A double-blind, vehicle-controlled study has been conducted to evaluate the safety and efficacy of Fungoid Tincture (Pedinol Pharmacal, Inc), for the treatment of fungal infection of the toenails. Ten patients with distal subungual onychomycosis were treated for twelve months with topical Fungoid Tincture. Another ten patients with the same ailment were treated with the vehicle alone. Once a month, clinical and global evaluation of the target nail was done, in addition to trimming and debridement of the nails. After twelve months of treatment, 90 percent of patients applying Fungoid Tincture showed negative results on culture. There were minimal adverse effects. Mucositis occurs in almost all patients treated with radiotherapy for head and neck cancer. The aim of this multicenter, double-blind, prospective, randomized trial was to evaluate the clinical efficacy of an economically viable antimicrobial lozenge (bacitracin, clotrimazole, and gentamicin [BcoG]) in the alleviation of radiation-induced mucositis in patients with head and neck cancer.
                One hundred thirty-seven eligible patients were randomized to treatment with either antimicrobial lozenge (69 patients) or placebo lozenge (68 patients). The primary end point of the study was the time to development of severe mucositis from the start of radiotherapy. Secondary end points included severity and duration of mucositis, pain measurement, radiation therapy interruption, and quality of life. Mucositis was scored using a validated mucositis scoring system.
                Toxicity profiles were similar between the two arms of the study. The median time to development of severe mucositis from the start of radiotherapy was 3.61 weeks on BCoG and 3.96 weeks on placebo (P =.61). There were no statistically significant differences between the arms in the extent of severe mucositis as measured by physician, in oral toxicities as recorded by patients, or in radiotherapy delays.
                This study was conducted on the basis of a pilot study that demonstrated the BCoG lozenge to be tolerable and microbiologically efficacious. A validated mucositis scoring system was used. However, in this group of patients treated with conventional radiotherapy, the lozenge did not impact significantly on the severity of mucositis. Whether such a lozenge would be beneficial in treatment situations where rate of severe mucositis is higher (ie, in patients treated with unconventional fractionation or with concomitant chemotherapy) is unknown. A reduction of symptoms of atopic dermatitis (AD) in small infants by the administration of Lactobacillus rhamnosus has been reported in a few studies. One study with older children and adolescents failed to show any effect.
                We conducted a prospective study to reassess the efficacy of orally administered L. rhamnosus strain GG (LGG) in infants with AD.
                In a randomized, double-blind, placebo-controlled study, 54 infants aged 1-55 months with moderate to severe AD were randomized to daily 10 x 10(9) colony-forming units of LGG or to placebo during an 8-week intervention phase. Emollients, class I-II topical corticosteroids and antihistamines were permitted.
                The treatment with LGG was well tolerated. At the end of treatment there were no significant differences between the groups with respect to clinical symptoms (SCORAD, pruritus, sleep loss), the use of topical corticosteroids and antihistamines, immunological parameters, or health-related quality of life of the parents.
                Our results could not confirm LGG as an effective treatment of AD in infancy. In a placebo-controlled double-blind study the prophylactic value of oral systemic treatment with the antimycotic agent miconazole was assessed in 30 highly predisposed patients receiving intensive cytostatic chemotherapy because of haematological malignancies. Patients colonized with Candida before treatment were not freed from this micro-organism by miconazole treatment. However, only 3 out of 6 initially non-colonized miconazole-treated patients became colonized during the study, against 10 out of 10 placebo-treated patients (p = 0.036). Seven out of 15 patients in the placebo group developed clinical mycosis, against only two out of 15 in the miconazole group. The miconazole-treated patients remained clinically free of mycosis for 252 out of 264 treatment days, while the placebo-treated patients remained free of mycosis for only 263 out or 338 treatment days (p = 0.0001). The results indicate that systemic miconazole treatment protects highly predisposed patients from colonization with Candida and prevents or postpones clinically established candidosis.
This review identified trial evidence for a range of different topical and systemic interventions for mycosis fungoides. Because of substantial heterogeneity in design, small sample sizes, and low methodological quality, the comparative safety and efficacy of these interventions cannot be established on the basis of the included RCTs. Taking into account the possible serious adverse effects and the limited availability of efficacy data, topical and skin-directed treatments are recommended first, especially in the early stages of disease. More aggressive therapeutic regimens may show improvement or clearance of lesions, but they also result in more adverse effects; therefore, they are to be considered with caution. Larger studies with comparable, clearly-defined end points for all stages of mycosis fungoides, and a focus on safety, quality of life, and duration of remission as part of the outcome measures, are necessary.
