Abstract

Background: Palmoplantar psoriasis is a therapeutically challenging condition that can significantly impact patient quality of life as it directly affects activities. However, despite this impact, few clinical studies address treatment. Herbs and their extracts have been used for treatment of skin disease for centuries. One of the most popular herbs in our society is black cumin or seed of blessing oil (Nigella Sativa); this plant had diverse clinically useful activity.Patients and Methods: This study was conducted in the Department of Dermatology and Venereology in Baghdad Teaching Hospital, Iraq during the period between January and October 2003. In this singleblind randomly controlled therapeutic study, thirty patients were enrolled, their ages ranged from 22-65 years. There were 18` females and 12 males. The patients were divided into 2 groups; group A (20 patient) instructed to use nigella sativa 10% ointment twice daily for 3 months, while group B (10 patient) used a control ointment(Vaseline) . Statistical analyses were carried out by computer using ttest, and chi-square when needed.Results: twenty-four patients completed the study. In group A (18 patients), we noted a significantly reduction of the thickness and fissuring of the skin of the affected part which was also become very soft after 3 months of therapy. The response of patients to treatment was good in 50%, moderate in 27.8% and mild response in 22.2%. The satisfaction of patients with treatment was full in 61.1%, partial in 27.8%, and no satisfaction in 11.1%. In group B (6 patients), the lesions showed no significant reduction after 3 months and the response of patients to treatment was good in 16.6%, moderate in 33.4%, and mild response in 50%. The satisfaction of patients with treatment in this group was full in 16.6%, partial in 50%, and no satisfaction in 33.4%. The difference in outcome after 12 weeks between the 2 study groups was statistically significant.Conclusion: The ointment of the black cumin is considered as a very good remedy for the palmoplantar psoriasis. This remedy is considered to be very safe, cheap and easy to prepare with no serious side effects as compared to the previous ointments for this type of psoriasis.

Summary:
Background: Palmoplantar psoriasis is a therapeutically challenging condition that can significantly
impact patient quality of life as it directly affects activities. However, despite this impact, few clinical
studies address treatment. Herbs and their extracts have been used for treatment of skin disease for
centuries. One of the most popular herbs in our society is black cumin or seed of blessing oil (Nigella
Sativa); this plant had diverse clinically useful activity.
Patients and Methods: This study was conducted in the Department of Dermatology and Venereology
in Baghdad Teaching Hospital, Iraq during the period between January and October 2003. In this single-
blind randomly controlled therapeutic study, thirty patients were enrolled, their ages ranged from 22-65
years. There were 18` females and 12 males. The patients were divided into 2 groups; group A (20
patient) instructed to use nigella sativa 10% ointment twice daily for 3 months, while group B (10
patient) used a control ointment(Vaseline) . Statistical analyses were carried out by computer using t-
test, and chi-square when needed.
Results: twenty-four patients completed the study. In group A (18 patients), we noted a significantly
reduction of the thickness and fissuring of the skin of the affected part which was also become very soft
after 3 months of therapy. The response of patients to treatment was good in 50%, moderate in 27.8%
and mild response in 22.2%. The satisfaction of patients with treatment was full in 61.1%, partial in
27.8%, and no satisfaction in 11.1%. In group B (6 patients), the lesions showed no significant reduction
after 3 months and the response of patients to treatment was good in 16.6%, moderate in 33.4%, and
mild response in 50%. The satisfaction of patients with treatment in this group was full in 16.6%, partial
in 50%, and no satisfaction in 33.4%. The difference in outcome after 12 weeks between the 2 study
groups was statistically significant.
Conclusion: The ointment of the black cumin is considered as a very good remedy for the palmoplantar
psoriasis. This remedy is considered to be very safe, cheap and easy to prepare with no serious side
effects as compared to the previous ointments for this type of psoriasis.
Key words: Black Cumin, Palmoplantar Psoriasis
Introduction:
Psoriasis is a chronic, unpredictable, and incurable
disease that, although not life-threatening, can severely
impair a patient’s quality of life (1) .The disease is
frequently complicated by pain and itching that can
disrupt everyday activities. Psoriasis causes significant
functional, psychological, and social problems (1, 2).
When psoriasis involves the palms and soles, it is
referred to as palmoplantar psoriasis. Palm and sole
involvement can be painful and disabling, as the acral
skin lesions can interfere with a variety of functions
(3,4).The pain and discomfort of palmoplantar
psoriasis could result in greater functional and social
disability than psoriasis located elsewhere on the body
(4).In recent years, the armamentarium of psoriasis
therapies has become a vast array of topical and
systemic treatments (5). For limited disease, topical
corticosteroids, topical vitamin D3 derivatives, topical
retinoids, intralesional corticosteroids, and /or the
excimer laser are commonly used (5,6). More
extensive disease is usually treated with light therapy,
*Department of clinical pharmacology, college of
medicine, university of Bahgdad
including broadband ultraviolet B, and psoralen
photochemotherapy, or systemic therapy such as
acitretin, methotrexate, cyclosporine, and/or an
immunobiologic drug (etanercept, infliximab,
adalimumab, alefacept, or efalizumab) (6,7). For the
patient whose psoriasis is treatment-resistant or who
experiences intolerable adverse effects to multiple
therapies, the alternative therapies must be kept in
mind (8, 9).
Black cumin is annular herbaceous plant, widely
cultivated throughout South Europe, Egypt, Syria,
Saudi Arabia, Turkey, Iran, and Iraq. Black cumin
contain both fixed and essential oils, proteins,
alkaloids, and saponin. Much of the biological activity
of the seeds has been shown to be due to
thymoquinone the major component of its oil (10).It
has been shown that Nigella sativa seed and oil are
effective anti-microbial (11), immunomodulatory (12),
antioxidant (13), anti-inflammatory (14) and with
antitumor activity (15). The diversity of therapeutic
activity of black cuminis due to the diversity of the
active compounds that it contains.
Remedy extracted from black cumin showed
promising results in many dermatological conditions.

Article
Palmoplantar pustulosis (PPP) is a chronic, relapsing, pustular eruption affecting the palms and soles for which treatment is often difficult and frustrating. Short-term colchicine has been used to treat PPP with variable response. We report on the successful treatment of 3 patients with severe, therapy-resistant, chronic PPP. We observed significant reduction in the frequency of pustular eruptions and the number of pustules with maximum tolerable doses of colchicine treatment for up to 12 months.

Dead Sea climatotherapy is highly effective in the treatment of psoriasis. However, its potential side effects, especially the risk of skin cancer, are unclear. We sought to determine the prevalence of solar damage and skin cancer among patients with psoriasis who underwent Dead Sea climatotherapy compared with control patients. This multicenter controlled cross-sectional study was carried out at the Dead Sea Solarium Clinic and outpatient clinics of the participating centers. A total of 1198 participants (460 patients with psoriasis and 738 control patients) aged 20 to 70 years were included. A standard questionnaire including demographic parameters and sun exposure habits was administered to all participants. Patients were questioned about previous psoriatic treatments and climatotherapy at the Dead Sea. All participants underwent a structured physical examination of the skin. We compared the prevalence of solar damage for patients with psoriasis and control patients and assessed the extent of photodamage among patients with psoriasis according to exposure time at the Dead Sea in univariate and multivariate analyses. Elastosis ( P < .001), solar lentigines (P = .03), poikiloderma (P < .001), and facial wrinkles (P < .001) were significantly more common among patients with psoriasis compared with control patients and showed a dose response with increased Dead Sea exposure time. Self-reported previous skin cancers were more common in control patients compared with patients with psoriasis (8.2% vs 3.5%, P = .002), however, the prevalence of nonmelanoma skin cancer on examination did not differ between the two groups. No cases of malignant melanoma were detected in either group. Dead Sea climatotherapy is not associated with an increased risk of malignant melanoma or nonmelanoma skin cancer for patients with psoriasis in Israel. However, UV exposure at the Dead Sea may play a role in the development of solar damage.
