A double-blind study was carried out to investigate the possibility of therapeutic effect of levamisole on recurrent progenital herpes. One hundred and nine patients, including 53 females, entered the study, but only 75 completed. Levamisole, 50 mg three times daily for 3 days, was started at the first sign of recurrence. The study period consisted of 6 visits or 12 months, whichever came first. No statistical differences were observed between levamisole and placebo groups when comparing the duration of the lesion and the degree of pain, although less pain was observed among those on levamisole. The interval between attacks was increasingly prolonged in the levamisole-treated group, and reached a significant level at the sixth visit. However, analysis on the basis of mean cumulative number of days between attacks showed no significant differences throughout the study period. Because of occasional neutropenia and generalized urticaria, and because of the absence of clear-cut clinical improvement of statistical significance, levamisole was considered of limited benefit to patients with recurrent genital herpes infection.

Lupus erythematosis is a nodular skin lesion that usually occurs on the inner surfaces of the extremities, and is 5-7 times more common in women than in men, particularly between 20-30 years of age. It is diagnosed by biopsy since the associated symptoms of malaise, fever, and arthralgia are variable. Known agents to induce lupus are streptococcal infection, sarcoidosis, tuberculosis, mycoses, medications particularly sulfa and oral contraceptive steroids, and a variety of other infections and allergies. A table is included in this review showing 8 cases of lupus erythematosus reported in the literature where oral contraceptive steroids were proved to be the etiologic factor, either by withdrawing and repeating pill prescription or by skin tests. The review ends with a list of other dermatological side effects of the pill, such as chloasma, acne, vaginal moniliasis, herpes, photosensitivity, and urticaria.

Photosensitivity diseases are reviewed. The pathogenesis of photodermatoses is not completely elucidated, especially because the photosensitizing agents are rarely identified. In exogenous photosensitization, the chemical agent (chromophore) is most often identified, reaching the skin either via topical contact or by systemic administration (drugs). Concepts of phototoxicity (photochemical reaction) and photo-allergy (photo-immunologic reaction) explain the clinical aspects. Dermatoses with photosensitivity are divided into three groups: photo-aggravated dermatoses (solar herpes, lupus erythematosus), photosensitivity caused by protective system defect (xeroderma pigmentosum), and photosensitivity caused by metabolic defects (porphyrias, pellagra). Idiopathic photodermatoses (unknown chromophore) are triggered by solar exposure (systemic photo-allergens would serve as mediators): 'benign estival polymorphous light eruption', polymorphous light eruptions, persistent light reactor, solar urticaria.

Herpes simplex diseases are among the most frequent sociomedical problems of our age. For the patients the recurrent diseases are particularly distressing depending on the frequency of relapse, their localization and clinical course. Immunological factors, especially cellular immune mechanisms seem to affect the frequency of relapse and particularly the clinical course of the relapse. Clinical experience so far with immunotherapy of relapsing herpes diseases with heat-inactivated herpes simplex virus antigen type 1 and type 2 are optimistic. Local painful swellings or more rarely the appearance of an urticaria have been described as side-effects within 10 years in 1 to 2% of patients.

The presence of Mycoplasma pneumoniae and/or herpes antigens was investigated by indirect immunofluorescence (IF) reactions in exfoliated cells or biopsy specimens from 43 patients with different skin diseases (treatment-resistant cutaneous herpes, genital herpes, acne, urticaria, dermatitis, erythema multiforme, ecthyma contagiosum). Either M. pneumoniae or herpes antigen could be detected in 21 (55.26%) and 12 (31.57%) of the 38 IF-positive cases, respectively, while the associated occurrence of mycoplasma and herpes antigens was observed in 5 (13.15%) of the patients.

In the treatment of exanthems, the first step is the elimination of the causal agent. Of great importance also is the symptomatic treatment of the cutaneous changes and such associated symptoms as itching and pain. The choice of the appropriate external medication and its vehicle will depend on the clinical findings, skin type, and the location of the skin lesions. The most important therapeutic principles are discussed taking drug-induced exanthema, acute urticaria and (herpes) zoster as examples.

Oral contraceptives (OCs) can affect the skin through their hormonal effects or through iatrogenic effects associated with their toxicity in certain individuals. They may also be beneficial in certain androgen-dependent dermatoses. Toxic effects of OCs are rare but potentially serious; they should be diagnosed early and require permanent termination of OC use. The clinical manifestations are variable and not specific to the medication. The most frequently reported manifestations are allergic vascularities which may lead to serious renal complications, fixed pigmented erythema, urticaria, which may have other etiologic factors, and lichenoid eruptions. Combined OCs, because of their estrogen content, may cause sensitivity to light in susceptible women. Other dermatoses can be initiated or aggravated by OCs without direct relation to their hormonal effects. OCs are therefore contraindicated if there is a personal or family history of porphyries or a personal history of systemic lupus erythematosus, erythema nouex, herpes gestationis, or malignant melanoma. Hormonal-related dermatological effects caused by either progestins or estrogens have become less frequent as dose levels have declined. Chloasma, either melasma or a poorly defined spotty pigmentation, accounts for 2/3 of cases of OC-related dermatoses. It is more common in women of Mediterranean background. 80% of affected OC users have a history of "mask of pregnancy", but the condition is also found in nulliparas. Exposure to sunlight is a factor. Women with a history of chloasma of pregnancy and dark coloring should not use OCs. Seborrhea is directly related to the androgen effect of OCs and is less likely to occur with 17 OH progesterone derivatives than with 19 norsteroid derivatives. The role of androgens in acne is well known, but 2 other factors are necessary: an anomaly in keratinization and proliferation of corynebacterium acnes, a saprophyte of the follicles. OCs do not necessarily need to be suspended during well-conducted acne treatment. Alopecia is rare but difficult to diagnose because of its psychological aspects. Androgenic alopecia is aggravated by progestins derived from 19 norsteroids. True hirsutism caused by an androgen-producing ovarian pathology is not related to OC use. Estrogens are incriminated in the etiology of telangiectasies, permanent dilatations of the arterioles. Once developed the condition does not regress and requires treatment with sclerosing agents, electrocoagulation, or laser. The various dermatological risk factors should be ruled out before prescription of an OC. Classic contraceptive pills are not commonly used in treatment of common acne because the strongly estrogenic climate required for therapeutic utility carries the risk of hypertriglyceridemia, thrombophlebitis, and possibly carcinogenesis. The recent development of pills containing the antiandrogen cyproterone acetate instead of a progestin in combination with ethinyl estradiol reduces androgenic effects in women. This pill may be useful in cases of severe acne, severe seborrhea, androgenic alopecia, or excessive facial hair.

The incidence of cutaneous effects of oral contraceptives (OCs) is estimated at 2.7-5%. Secondary effects directly attributable to the hormonal action of OCs include melasma, acne and hyperseborrhea, alopecia, and cutaneous lesions of vascular origin. Melasma or chloasma accounts for about 2/3 of all cutaneous side effects of OCs. It appears from 1 month-3 years after the start of OC use, its frequency increasing with dose and duration of use. Pigmentation appears to accentuate the symptoms in brunettes rather than predisposing them to melasma. Exposure to the sun plays a certain role, but use of a low dose OC and effective sun protection are not enough to reverse the pigmentation. These melasmas regress more slowly than after pregnancy and many remain definitive. The influence of OCs on acne is variable, with some OCs provoking sebaceous hypersecretion and some improving acne enough to be used for treatment. For the therapeutic effect to be observed, the estrogen dose must be sufficient to offset the androgenic effect of the progestin. Combined pills containing the strong antiandrogen cyproterone acetate should control acne if other, less androgenic progestins fail. Alopecia is a very rare effect of OCs and its appearance may even reflect simple coincidence. Vascular complications of combined OCs are dependent on estrogens and may include such manifestations as telangiectasias, angiomas, and livedo reticularis. Some secondary cutaneous effects are probably not due to a hormonal influence. They are less well known than the direct hormonal effects, and publications concerning the often detail isolated observations that are difficult to interpret. Reactions of hypersensitivity or allergy to combined OCs may include urticaria and eczema. A history of OC use should be sought in all women presenting with erythema nodosum and the OCs should be discontinued. Pruritus and jaundice may be observed in 1 OC user in 100,000. They indicate a cholestatic hepatitis for which estrogens are responsible. Most patients developing the condition have already had pruritus or jaundice during pregnancy; such a history contraindicates OC use. Several dermatological and systemic disorders are aggravated by OC use. Hereditary angioedema, herpes gestationis, porphyries, and systemic lupus erythematosus are exacerbated by OC use. The role of OCs in malignant melanomas remains controversial.

The role of infectious agents as a cause of chronic idiopathic urticaria (CIU) is uncertain. The objective of this study was to investigate whether genital herpes simplex infection is causally related to CIU. We identified two patients with recurrent genital herpes simplex infections associated with CIU. Episodes of genital herpes were especially associated with acute exacerbation of urticaria. Anti-herpes simplex 2 antibodies and Tzanck smears were done in both patients, along with other relevant investigations for CIU. Acyclovir was added to antihistamine therapy. Both patients were apparently in good health and appeared clinically immunologically stable, though one of them was found to be diabetic. Clinical and laboratory investigations for genital lesions supported a diagnosis of herpes simplex. Anti-herpes simplex 2 antibodies were markedly raised in both patients. The Tzanck smear was positive in one case and negative in the other, despite a definitive clinical diagnosis of herpes progenitalis. CIU, which was inadequately controlled with antihistamines alone, responded dramatically to the addition of acyclovir therapy. Our results may not be applicable to other patients with CIU, especially when there is inadequate evidence of an association with genital herpes. CIU may be associated with recurrent genital herpes simplex infection. In such situations, the addition of acyclovir to therapy may be beneficial.
