[Modification of skin sensitivity to selective UV-B (SUP) by water baths and various saline solutions--effect of various concentrations, duration of effect].

The skin sensitivity against selected UV-B (SUP) can be improved by baths in water or in salt solutions, leading to an average economizing of the radiation dose of about 50%. The best effect is achieved by a 0.3% salt bath (0.5 kg common salt per bath-tub). As the effect lasts for two hours, balneophototherapy may be carried out not only in hospitals but in practices, as well.

[Experiences in dermatologic practice with combined external treatment of acne with benzoyl peroxide and erythromycin].

Fifty patients consulting my dermatologic practice because of facial papulopustular acne varying from grade I up to grade IV (according to Plewig and Kligman) have been treated with benzoyl peroxide and erythromycin. The more severe cases (grades III and IV) received additional treatment, such as tetracycline or cyproterone acetate internally and/or, externally, removal of comedones as well as UV-A-radiation. As a result, 68 percent of all patients showed remission in at least 70 percent of their inflammatory skin eruptions.

Quantitation of sensitization and responsiveness to dinitrochlorobenzene in normal subjects.

Dinitrochlorobenzene (DNCB) has been used widely to assess cell-mediated immunity in man. However, previous workers have evaluated response qualitatively and subjectively. Such methods cannot elucidate the quantitative relationships between stimulus and response essential to an understanding of the functional components of the system. We have developed quantitative techniques to explore the dose-response relationships of both afferent and efferent limbs of the response, and used this method to examine changes in reactivity to DNCB after exposure to UV radiation and in people with contact allergies.

Are topical corticosteroids useful adjunctive therapy for the treatment of psoriasis with ultraviolet radiation? A review of the literature.

Adjunctive topical corticosteroids are often administered with UV-B phototherapy or oral psoralen plus UV-A (PUVA) photochemotherapy for the treatment of psoriasis. Five studies comparing PUVA alone with PUVA and topical corticosteroid preparations showed more rapid rates of clearing and a smaller total UV-A exposure with the latter regimen. However, one study demonstrated a higher relapse rate in association with corticosteroid use. Further studies to better define these risks are recommended. Six of seven reports evaluating the use of topical corticosteroid preparations with UV-B phototherapy failed to demonstrate an advantage to this regimen when compared with UV-B phototherapy alone. Therefore, the use of a topical corticosteroid preparation with UV-B phototherapy for the treatment of psoriasis is not recommended.

Treatment of severe Raynaud's syndrome by injection of autologous blood pretreated by heating, ozonation and exposure to ultraviolet light (H-O-U) therapy.

OBJECTIVE: To determine the effect of re-injection of small samples of autologous blood, pretreated with heat, ozone and ultraviolet light (H-O-U therapy) in patients with severe Raynaud's syndrome. EXPERIMENTAL DESIGN: Open trial in 4 patients. SETTING: Temperature/humidity controlled vascular laboratory. PATIENTS: Severe Raynaud's syndrome of more than 5 years duration and defined as more than 5 attacks daily or 10 attacks in one week, at least half of which were painful and lasting for more than 30 minutes. Three patients were refractory to infusions of Iloprost. INTERVENTIONS: Patients were treated daily or on alternate days for a two to three weeks period by re-injection of citrated autologous blood pre-treated with heat, ozone and ultraviolet light (H-O-U therapy). MEASURES: Clinical observations; mean equilibrated hand temperature (infrared thermography); distributive and microcirculatory blood-flow (venous occlusion strain-gauge plethysmography, infrared photoplethysmography, laser Doppler flowmetry) iontophoresis of acetylcholine and sodium nitroprusside; estimations: serum levels of 6-keto-PGF1alpha and serum levels of anti-hsp65 antibody. RESULTS: Reduction or abolition of Raynaud's attacks for at least three months after treatment. Mean equilibrated hand temperature increased but did not normalise. Blood flow parameters improved but did not reach statistical significance. Iontophoresis of acetylcholine showed an increase in laser Doppler flowmetry which was statistically significant. Serum levels of 6-keto-PGF1alpha, fell significantly in three patients. Serum levels of anti-hsp65 antibody fell in the one patient which was followed sequentially. CONCLUSIONS: H-O-U therapy may prove useful in patients with severe Raynaud's syndrome.

Subacute cutaneous lupus erythematosus during PUVA therapy for psoriasis: case report and review of the literature.

Lesions typical of subacute cutaneous lupus erythematosus developed in an elderly woman after 6 months of PUVA (8-methoxypsoralen and longwave ultraviolet light) therapy for psoriasis. Pancytopenia, antibodies to double-stranded DNA, and hypocomplementemia developed concurrently with the appearance of the cutaneous lesions. With discontinuation of photochemotherapy, the cutaneous lesions disappeared and the pancytopenia improved.

Efficacy of acitretin and commercial tanning bed therapy for psoriasis.

OBJECTIVE: To assess the efficacy of acitretin and commercial tanning bed therapy for the treatment of moderate to severe chronic plaque-type psoriasis. DESIGN: Retrospective medical record review and telephone survey of subjects and prospective open-label trial. SETTING: University dermatology clinic. PATIENTS: The study population comprised 26 subjects in the retrospective study and 17 subjects in the prospective study, all with moderate to severe plaque-type psoriasis. INTERVENTION: Twelve weeks of daily oral acitretin (25 mg) therapy and commercial tanning bed UV exposure (mean UV-B output of 4.7%) for 4 to 5 days per week. RESULTS: In the retrospective review, 19 (83%) of 23 subjects had clearance or near clearance, 2 (9%) of 23 had moderate improvement, and 2 (9%) of 23 had no improvement. Patients reported a high degree of satisfaction with the treatment. In the prospective trial, the Psoriasis Area and Severity Index (PASI) and National Psoriasis Foundation scores decreased an average of 78.6% and 79.0% from baseline, respectively. A reduction from baseline in the PASI score of 50% and 75% (PASI 50 and PASI 75) was achieved by 13 (76%) and 10 (59%) patients, respectively. Adverse events were generally mild to moderate. CONCLUSIONS: Acitretin use in combination with commercial tanning bed therapy appears to be effective and useful for psoriasis in areas without access to physician-directed phototherapy. The variability of tanning salon light and quality mandates caution when using this therapy.

Randomized double-blind trial of the treatment of chronic plaque psoriasis: efficacy of psoralen-UV-A therapy vs narrowband UV-B therapy.

OBJECTIVE: To compare the efficacy of oral psoralen-UV-A (PUVA) therapy with that of narrowband UV-B (NB-UVB) therapy in patients with chronic plaque psoriasis. DESIGN: Double-blind randomized study. SETTING: Phototherapy unit in a university hospital. Patients Ninety-three patients with chronic plaque psoriasis. Interventions Twice-weekly NB-UVB or PUVA therapy, starting at 70% of the minimum phototoxic or erythema dose, with 20% incremental increases. Patients were treated until clearance, up to a maximum of 30 sessions; those with clearance were followed up until relapse or for 12 months. MAIN OUTCOME MEASURES: Proportion of patients achieving clearance, number of treatments to clearance, and, among those with clearance, the proportion remaining in remission at 6 months. RESULTS: Patients with skin types V and VI had a lower rate of clearance than those with skin types I through IV (24% vs 75%; P = .001). In patients with skin types I through IV, PUVA was significantly more effective than NB-UVB at achieving clearance (84% vs 65%; P = .02). The median number of treatments to clearance was significantly lower in the PUVA group (17.0 vs 28.5; P<.001). More patients treated with PUVA vs NB-UVB were reported to have erythema at some stage during treatment (49% vs 22%; P = .004), although this difference may have been due to ascertainment bias. Six months after the cessation of therapy, 68% of PUVA-treated patients were still in remission vs 35% of NB-UVB-treated patients. Conclusion Compared with NB-UVB, PUVA achieves clearance in more patients with fewer treatment sessions and results in longer remissions.
