We describe an 18-month-old male infant suffering from the ichthyosis follicularis, atrichia, and photophobia (IFAP) syndrome and further delineate the clinical phenotype. Severe retardation of growth and psychomotor development, chill-like seizures, bronchial asthma, urticaria, a proneness to skin infections and transient nail dystrophy observed in our patient are non-obligatory manifestations of this disorder. Histological examination of the atrichia revealed poorly developed, shortened hair follicles and a complete absence of sebaceous glands. The sex ratio of published cases suggests an X-linked recessive inheritance. The marked clinical variability of the IFAP syndrome might be the expression of a contiguous gene defect.

The expression of the CD36 (OKM5) antigen was studied with the PAP technique on sections of skin from healthy subjects and of normal and diseased skin from patients with various skin diseases. In specimens from healthy subjects the antigen was found on vascular and perivascular structures and in some cases it was seen on cells of the acrosyringium. A net-like pattern of CD36 was observed in the upper part of the stratum spinosum in skin lesions of patients with psoriasis, lichen planus, pityriasis rosea, morbilliform drug reactions, necrobiosis lipoidica, lichen amyloidosus, Darier's disease and ichthyosis vulgaris. Expression of CD36 was also seen in the nonlesional skin just below the granular layer in 3 of 5 patients with factitial urticaria with immediate dermographism, but not in delayed dermographism or chronic urticaria. In ichthyosis vulgaris CD36 was also expressed in dendritic cells of the basal layer and in a patient with a graft versus host reaction it was recognized both on scattered keratinocytes and on dendritic cells in the epidermis. The role of the expression of the CD36 antigen in the skin is unknown. The activated cells might possibly serve as antigen-presenting cells and/or have a modulatory influence on an inflammatory reaction.

The localization of transferrin and C3d receptors in various skin lesions and normal appearing skin have been studied on sections with the PAP technique. The transferrin receptor was recognized in the lower epidermis from psoriatic plaques. Here it was more evident than in other inflammatory or hyperproliferative disorders where it was mainly detected on the basal cells. In healthy skin or lesions of lichen planus, scleroderma and ichthyosis the transferrin receptor was not detected in the epidermis. The C3d receptor was in normal skin found on the basement membrane and on elastic fibres in the papillary dermis. The basement membrane was strongly marked in pemphigoid but was not seen in lichen planus and Ehlers-Danlos syndrome. In patients with urticaria factitia, contact dematitis, psoriasis and Darier's disease the suprabasal cells also expressed C3d whereas in other dermatoses the epidermis was negative. Colloid bodies in lichen planus and GVH reactions expressed both the transferrin receptor and C3d.

A total of 900 consecutive newborns delivered at the Nehru Hospital, Chandigarh, India, over a period of 7 months were examined for presence of skin lesions within 48 hours of birth. Commonly observed skin lesions were Epstein pearls (88.7%), mongolian spots (62.2%), milia (34.9%), sebaceous hyperplasia (31.8%), salmon patches (28.4%), and erythema toxicum neonatorum (20.6%). These figures are comparable with earlier reports. Impetigo neonatorum occurred in 11.3% of infants, and was frequent in our hot and humid climate from May to August. Traumatic skin lesions were most often present in babies who had forceps deliveries. Three hundred ten (34%) babies were available for follow-up up to six weeks. Additional skin lesions observed were omphalitis (16 babies), oral thrush (9) and postinflammatory hypomelanosis (8). Three infants had atopic dermatitis, two each had seborrheic dermatitis, diaper dermatitis, pityriasis versicolor, and nevus achromicus. One each had vitiligo, ichthyosis vulgaris, urticaria, and strawberry hemangioma. These observations highlight the importance of repeat examination for the appearance of skin lesions during the neonatal period.

A total of 2,951 determinations of total IgE serum levels in dermatologic patients revealed significantly elevated geometric mean values in 18 of 25 diagnostic groups. The highest IgE concentrations (geometric mean greater than 100 kU/l) were found in atopic diseases (atopic eczema, extrinsic asthma, allergic rhinitis), scabies, ichthyosis vulgaris and diseases of the prurigo group. Furthermore, total IgE was elevated in acute, chronic, and physical urticaria, in patients with immediate-type allergies, in various kinds of eczema, in patients with characteristic features of atopy (typus atopicus), in psoriasis, in pyogenic skin infections, and alopecia areata. The range of individual IgE values was wide: in all diagnostic groups individual IgE levels beneath the normal adult geometric mean of 14 kU/l were found; the maximum concentrations were 340-47,000 kU/l, thus exceeding the upper limit of 100 kU/l for individual values. Knowledge of the patient's clinical condition is a prerequisite for the diagnostic interpretation of an individual total IgE serum level.

Muckle-Wells syndrome is a rare autosomal dominant disorder characterized by chronic recurrent urticaria, periodic arthritis, sensorineural deafness, general signs of inflammation, and secondary amyloidosis (AA type). We report on a 4-generation family with 7 persons sharing various signs of this syndrome associated with bipolar aphthosis in 5 cases and cystinuria in one. Two other relatives in the family had ichthyosis.

We present a case of trichothiodystrophy associated with a hypereosinophilic syndrome. This case had been followed for 30 years. Trichothiodystrophy was characterized by lamellar ichthyosis, hair and nail dystrophies, kyphoscoliosis, congenital luxation of the hip. The hypereosinophilic syndrome was characterized by an itching urticaria-like eruption. Although the patient's general condition had remaining stable for 30 years, during the last year it worsened and the patient suddenly died. The authors discuss about the significance of this association.

Allopurinol is widely prescribed for primary and secondary hyperuricaemia, and cutaneous adverse reactions are seen in 0.8-2.1% of recipients. The majority of these are mild and include pruritus, diffuse or maculo-papular erythema, urticaria and ichthyosis. More severe reactions are well recognized and include exfoliative dermatitis, toxic epidermal necrolysis and a generalized hypersensitivity syndrome. The latter typically comprises fever, rash, hepatic and renal dysfunction and eosinophil leucocytosis. The occurrence of toxic pustuloderma due to allopurinol, confirmed by re-challenge, is reported.

Four hundred children, up to the age of 12 years, attending dermatological outpatients' department (OPD) in Irwin group of hospitals, Jamnagar were studied in detail. Desired investigations were done in addition to routine blood, urine, and stool examinations. Maximum number of cases (43.50%) were found in school going children. Highest number of cases were of skin infections (83.25%) followed by allergic (8.5%) and miscellaneous disorders (8.25%). Out of 333 cases of skin infections, 137 (41.14%) were of pyoderma, 113 (33.93%) of parasitic infections, 45 (13.51%) of fungal infections and 35 (10.51%) of viral infections. Amongst allergic disorders, atopic dermatitis was commonest followed by papular urticaria, unclassified eczema and contact dermatitis. Thirteen types of miscellaneous disorders (33 cases) were noted. Commonest being vitiligo (8 cases) and epidermolysis bullosa and ichthyosis, 6 cases each. Unhygienic living conditions seem to be an important factor responsible for higher incidence of skin infections in developing countries.

Moisturizers are widely used in various dermatologic and cosmetic skin therapies. Different classes of moisturizers are based on their mechanism of action, including occlusives, humectants, emollients and protein rejuvenators. Commercially available moisturizers often utilize components of each of these classes to provide their beneficial effect. Dry skin (xerosis) is the major indication of use. Others include atopic dermatitis, irritant contact dermatitis, ichthyosis, and dermatoheliosis. Although generally efficacious, moisturizers can cause a number of unwanted side-effects, including occlusive folliculitis, irritation, allergic contact dermatitis and contact urticaria.
