Honey has antibacterial, antifungal and antioxidants activities and has high nutrient value. In this study we investigated the potential use of topical application of crude honey in the management of seborrheic dermatitis and dandruff. Thirty patients with chronic seborrheic dermatitis of scalp, face and front of chest were entered for study. Twenty patients were males and 10 were females, their ages ranged between 15 and 60 years. The patients had scaling, itching and hair loss. The lesions were scaling macules, papules and dry white plaques with crust and fissures. The patients were asked to apply diluted crude honey (90% honey diluted in warm water) every other day on the lesions with gentle rubbing for 2-3 mins. Honey was left for 3 hr before gentle rinsing with warm water. The patients were followed daily for itching, scaling, hair loss and the lesions were examined. Treatment was continued for 4 weeks. The improved patients were included in a prophylactic phase, lasting six months. Half patients were treated with the topical honey once weekly and the other half served as control. All the patients responded markedly with application of honey. Itching was relieved and scaling was disappeared within one week. Skin lesions were healed and disappeared completely within 2 weeks. In addition, patients showed subjective improvement in hair loss. None of the patients ( 15 patients) treated with honey application once weekly for six months showed relapse while the 12/15 patients who had no prophylactic treatment with honey experienced a relapse of the lesions 2-4 months after stopping treatment. It might be concluded that crude honey could markedly improve seborrheic dermatitis and associated hair loss and prevent relapse when applied weekly.

Itching is a common complaint among patients infected with HIV and may cause significant morbidity and embarrassment. Although idiopathic HIV-pruritus has been described, it is probably less common than was previously thought. In most patients, a careful history and physical examination will show that a dermatosis accounts for their pruritus. Dry skin, seborrheic dermatitis, eczema, psoriasis, pruritic papular eruption, staphylococcal folliculitis and prurigo nodularis are frequently encountered in these patients. These common dermatoses, drug eruptions, several rarer conditions and systemic causes of itching should be excluded before diagnosing idiopathic HIV-pruritus. Treatment should be directed to the underlying skin problem and may be supplemented with sedating antihistamines. Phototherapy is a safe and effective therapeutic modality for many pruritic dermatoses as well as for idiopathic pruritus.

Pityrosporum ovale appears to play an important role in the pathogenesis of dandruff as a symptom of seborrheic dermatitis. Climbazole is an antimycotic agent with a high in vitro and in vivo efficacy against P. ovale. In the presented work we investigated the efficacy and safety of a climbazole 0.65% shampoo on seborrheic dermatitis of 30 volunteers. Subjects were diagnosed as having moderate to severe seborrheic dermatitis of the scalp. After a 1-week washout and a 4-week treatment the clinical evaluation showed a successful reduction of dandruff, skin redness and itching in 80% of the volunteers and a mild improvement in 20% of the volunteers. The cosmetic acceptability was very good by the majority. It is concluded that the formulation tested is effective in the treatment of moderate to severe dandruff.

Psoriasis of the scalp is a frequently occurring condition affecting approximately 2% of the Western population. The sharply demarcated erythematosquamous lesions with silver-white scaling characterize scalp psoriasis. Quality of life can be seriously reduced by this condition and therefore long term treatment is needed in most patients. Coal tar shampoos, containing 2 to 10% coal tar solution, are effective in scalp psoriasis. However, no double-blind studies are available to support such an assumption. Salicylic acid 5 to 10% has a pronounced keratolytic effect. Salicylic acid should be formulated in an ointment, which can be washed off easily. Crude coal tar is the most effective tar available for the treatment of psoriasis. An important feature of coal tar is its potent efficacy against pruritus. At the scalp, the application of crude coal tar is difficult. Therefore coal tar solution is the most frequently applied tar preparation in scalp psoriasis. Dithranol 0.1 to 3% is manufactured in various formulations. Treatment is initiated at a low concentration and the concentration is increased stepwise until a slight irritation, the feeling of warmth, is reached. In the treatment of scalp psoriasis, cream formulations are used. Imidazole antifungals have been used with success in scalp psoriasis. Overgrowth of the scalp with pityrosporon is a well-known feature of scalp psoriasis and seborrheic dermatitis. In case of resistance to other topical treatments use of a topical or systemic imidazole derivative might be helpful. So far, topical corticosteroids are the most frequently used treatments for psoriasis of the scalp. Corticosteroids inhibit epidermal proliferation, inhibit inflammation and modulate immune functions. Topical corticosteroids are fast acting: within 3 to 4 weeks maximal efficacy is reached. No data are available to support the efficacy and safety of topical corticosteroids during long term use. However, from epidemiologic surveys we know that these treatments are used by the majority of patients for more than 8 weeks. Since 1992 vitamin D3 formulations have been developed for the treatment of psoriasis. Calcipotriol is available in most countries. Tacalcitol is available in Japan and several other countries. Vitamin D3 analogues inhibit epidermal proliferation, enhance cornification and inhibit inflammation. Therefore, vitamin D3 analogues have a substantial antipsoriatic effect. Systemic treatments such as methotrexate, cyclosporine and acitretin are indicated in patients with recalcitrant disease. Management of scalp psoriasis requires long term strategies in order to reach an optimal improvement of the condition, while avoiding the adverse effects associated with the long term use of treatments.

After more than a decade of use, topical minoxidil solution has proven to be a safe and effective treatment for androgenetic alopecia. However, some patients present with complaints of pruritus and scaling of the scalp. The most common causes of these symptoms include irritant contact dermatitis, allergic contact dermatitis, or an exacerbation of seborrheic dermatitis. Patients suffering from allergic contact dermatitis may benefit from patch testing to determine the causative allergen. Among the patients we patch tested, propylene glycol was found to be the contactant in a majority of cases, not the minoxidil itself. Many of these patients may be candidates for treatment with alternative formulations using other solvents, such as butylene glycol, polysorbate, or glycerol. Although predictive, patch testing results do not ensure that the compounded preparations will be tolerated. Unfortunately, patients found to be allergic to minoxidil are no longer candidates for topical treatment of their alopecia with any preparations of minoxidil.

A randomized, double-blind, placebo-controlled trial of P07P, a product derived from a traditional Chinese herbal remedy, was undertaken in 50 dogs with atopic dermatitis. Owners recorded a daily itch score for 4-14 days before treatment and during treatment. Packets of powder containing P07P or placebo were added to the food once daily for 8 weeks. Dogs were assessed for erythema, surface damage, overall coat condition and seborrhoea by the same investigator, as well as for pruritus and general demeanour, at 0 (visit 2), 28 (visit 3) and 56 (visit 4) days of treatment or at withdrawal. Investigator and owner assessments of response were recorded after 28 and 56 days of treatment or at withdrawal. The predefined primary outcome measure was the owners' assessment of response at the end of treatment. Nine of the 24 dogs (37.5%) in the P07P group but only 3 of the 23 dogs (13%) in the placebo group were considered to have improved, but this difference was not statistically significant (P = 0.09). There was a significantly higher withdrawal rate due to worsening of condition in the placebo group (P = 0.04). Mean daily itch score in the second 28-day period of the study was significantly higher than baseline in the placebo group (P = 0.01) but not in the P07P group (P = 0.30). Pruritus scores showed a significant deterioration from baseline at the final visit in the placebo group (P = 0.01) but not in the P07P group (P = 1.00). There was a significant difference between the groups in change from baseline in erythema score at visit 3 (P = 0.05). There were no significant differences (P > 0.05) in surface damage, seborrhoea, overall coat condition and general demeanour scores within or between the groups throughout the study. The product was well tolerated with no severe or serious adverse events recorded. P07P may be beneficial as a novel nonsteroidal therapy for the management of dogs with atopic dermatitis.

The purpose of this study was to determine under carefully controlled clinical conditions the relative anti-inflammatory and anti-pruritic action of betamethasone as compared with prednisone and a placebo. A total of 130 consecutive patients with atopic dermatitis, primary irritant dermatitis, nummular eczema, allergic eczematous contact dermatitis, sweat retention, seborrheic dermatitis and pruritus were selected for study. Under the conditions of this clinical trial, the samples indicated a difference in anti-inflammatory and anti-pruritic response to the therapeutic agents used. The difference between betamethasone and the placebo was highly significant, and the difference in these measured responses was studied on the basis of a careful evaluation and statistically. The result of this study corroborates statistically our clinical impression regarding the therapeutic effect of betamethasone.

The scalp is a unique site of the human body that may exhibit some particular physiopathological reactions. A few manifestations are paroxysmal. The main ones are the acute pruritus of pediculosis, and the pruritus at onset of dandruff or seborrhoeic dermatitis. One must add the telogen effuvium after solar exposure or during the post-partum, and the anagen dystrophic alopecia following chemotherapy. Other paroxysmal events include acute canitia and alopecia areata.

A maculopapular eruption with clinical and histological features similar to those previously described in Sphinx cats under the name of urticaria pigmentosa is reported in five unrelated Devon Rex cats. Physical examination revealed erythematous, occasionally crusted papules, with a bilaterally symmetrical linear distribution on the latero-ventral trunk in two cases and a diffuse distribution on the ventral thorax in the other three cats. One cat also had a greasy seborrhoea on the head and dorsum. Pruritus and pigmented macules were present only in cats affected by secondary bacterial infection. Histological examination of papules in all cats and of the lesional skin of the cat affected by greasy seborrhoea revealed the presence of a perivascular to diffuse mastocytic and eosinophilic infiltrate in the dermis. The mean numbers of nondegranulated and degranulated mast cells per mm(2) were 303.2 and 451.6, respectively. The condition waxed and waned in all cats, and exacerbations were controlled with prednisolone or essential fatty acids.

Ciclopirox (Loprox) is a broad-spectrum antifungal medication that also has antibacterial and anti-inflammatory properties. Its main mode of action is thought to be its high affinity for trivalent cations, which inhibit essential co-factors in enzymes. Clinical trials have shown that ciclopirox gel is a successful treatment for seborrheic dermatitis of the scalp as well as for tinea pedis. Adverse effects are generally mild and include a skin-burning sensation, contact dermatitis, and pruritus. Ciclopirox is indicated in the US for the treatment of tinea pedis, tinea corporis, pityriasis versicolor, seborrheic dermatitis, and cutaneous candidiasis.
