[Measles: a follicular disease]. / La rougeole, une maladie folliculaire.

BACKGROUND: Since the year 2000, measles epidemics have occurred throughout Europe, with a number of severe cases in adults leading to hospitalisation. Herein, we discuss the case of a young adult male with measles presenting clinical and histological features of rash having a follicular nature. PATIENTS AND METHODS: An 18-year-old male consulted for diffuse, febrile morbilliform exanthem consisting chiefly of follicular papules surrounded by erythematosus macules. In the absence of any features suggesting possible contagion or implicated medication, biopsy was performed on one of these elements and showed strictly follicular involvement. Perifollicular lymphocytic inflammation was noted, with necrotic keratinocytes having monster nuclear cells, and above all, multinucleated cells within the outer root sheath and the sebaceous gland. Positive IgM measles serology was noted. DISCUSSION: Follicular involvement is a very common feature in cases of measles that we have seen in recent years. In the present case, histological examination showed a follicular and sebaceous cytopathogenic effect, which while far less well known, has occasionally been seen with measles in the sweat glands or the epidermis, in which viral presence was detected. Thus, the skin rash was accounted for at least in part by the presence of the virus itself within keratinocytes and adnexal cells. This follicular involvement of measles, histologically confirmed in the present case, is frequently seen and can be helpful in differential clinical diagnosis with regard to other viral rashes. It could be caused by special affinity of the virus for body hairs.

Results of a public awareness campaign in Morocco regarding the sun's deleterious effects.

OBJECTIVE: To investigate knowledge of the various sun radiation-related risks and awareness of photoprotection measures using a sample of the Moroccan population. METHODS: An investigation of prevalence, which was administered while a public awareness campaign on the sun's harmful effects, organized by the department of dermatology of Ibn Sina's hospital in Rabat, was running. The collection of the data was made on the basis of a questionnaire that was filled by the team of the doctors of the department. The logistic regression allowed to identify the explanatory factors for the prevalent knowledge and behaviours related to the subject in hand. RESULTS: Four hundred eleven subjects were included in the survey. The subjects' average age was 40 +/- 10 years. Eighty-four per cent were female. The analysis of the total score of knowledge related to the sunrays' deleterious effects demonstrated low levels of knowledge among 160 participants (38.9%). Females were clearly more knowledgeable than the opposite sex (P = 0.003) and also those having a higher educational level (P = 0.006) scored high. The use of sunscreens was recognized by 52.8% of the patients and was associated with female gender and higher educational level. CONCLUSION: Our study reports the results of the first public awareness campaign on the sun's deleterious effects on the Moroccan population, inclusive and relevant to all ages. Awareness of the sun's radiation-related risks in a country as sunny as ours is low, whereas different measures of photoprotection are rather well known. Messages adapted to the characteristics of our population are a necessity.

Oto-Rhino-Laryngology (ORL) tumor presentation in a case of systemic AA amyloidosis.

A 64-year-old male with no underlying disease presented with the development of multiple skin nodules, loss of sensation in the extremities, hoarseness, macroglossia, and pain in the oral cavity. Direct laryngoscopy showed nodules involving the oral cavity, oropharynx, supraglottic region, and vocal cords. Biopsy from skin nodules showed amyloid deposits staining with Congo red. Immunohistochemical staining was used for AA protein and was positive. Biopsy from the oral floor was also positive for amyloid. Oto-Rhino-Laryngology (ORL) involvement has been reported in approximately 40 percent of AL amyloidosis patients, but does not appear to be frequent in AA amyloidosis. Cutaneous manifestations in AA amyloidosis are rare, although cases with lesions presenting as purpura are reported occasionally; we are not aware of other cases of ORL nodular involvement in systemic AA.

[Juvenile dermatomyositis: 4 case studies]. / La dermatomyosite juvénile: à propos de 4 cas.

Juvenile dermatomyositis is a rare disease. The estimated incidence is 2 to 3 cases per million population. Before the use of corticosteroids, prognosis was poor for most patients. Today, despite a better prognosis, the side effects of long-term treatment still burden the outcome of the disease. The diagnosis of this entity is difficult and often delayed due to its rarity. It has been shown that the delay in diagnosis and care is a major factor for poor prognosis. Cutaneous findings are often inaugural, allowing early diagnosis. This study's aim was to share our 10-year experience with juvenile dermatomyositis.

Childhood cutaneous leishmaniasis: Experience of a Moroccan unit of dermatology.

OBJECTIVE: We undertook a monocentric retrospective analysis of childhood leishmaniasis in order to describe the epidemio-clinical profile, therapeutic characteristics and clinical outcomes of affected patients. PATIENTS AND METHODS: The files of all children treated for cutaneous leishmaniasis (CL) in the Dermatology Department of Ibn Sina University Hospital over an 11-year period were reviewed. RESULTS: A total of thirteen children were included. The mean age was 10.2 years and the sex ratio (F/M) was 5.5. All patients lived or had stayed in an endemic area. The average delay of diagnosis was 11.8 months. The most frequent clinical finding consisted of ulcers (61.5%), usually located on the face (69.2%). The clinical diagnosis was confirmed by parasitologic smear in 76.9 percent of cases. The treatment used was intralesional meglumine antimoniate in twelve cases. The outcome was favorable in all cases. CONCLUSION: Our series is characterized by a female predominance and the patients presented with a single lesion. The lesions were frequently located on the face and a favorable outcome was obtained after treatment with intralesional meglumine antimoniate.
