Psoriasiform acral dermatitis: a peculiar clinical presentation of psoriasis in children.

Recently an unusual chronic dermatosis, considered a new clinical entity and closely resembling psoriasis, has been described in the literature under the term psoriasiform acral dermatitis (PAD). It is characterized by cutaneous involvement of the digits without nail dystrophy. We describe three young patients, ages 6 to 8 years, in whom this condition was associated with psoriasis. Two children were affected by psoriasis vulgaris, while the third had a palmoplantar psoriasis. All laboratory investigations performed were within normal limits. Skin biopsy specimens taken from the fingers of two patients revealed the pathologic features of subacute spongiotic dermatitis. Histologic examination of a biopsy specimen taken from an erythematous squamous patch confirmed the clinical diagnosis of psoriasis in two patients. The dermatitis showed a fluctuating course in all three patients, with only a moderate to strong improvement with therapy with calcipotriol ointment (50 microg/g). During follow-up, two patients experienced marked spontaneous, persistent improvement, while the disease slightly worsened in the third. The children had features similar to those described in PAD, but were also suffering from psoriasis. Whether PAD is a distinctive entity or just a clinical manifestation of psoriasis in children is still an open question. We strongly believe this latter hypothesis, although further studies are needed to confirm it.

Pachydermodactyly in two young girls.

Pachydermodactyly is a benign, superficial fibromatosis frequently observed in young males. We describe the condition in two young girls affected by Ehlers-Danlos syndrome (EDS) and tuberous sclerosis, respectively. We hypothesized that in the patient with tuberous sclerosis, pachydermodactyly is a clinical manifestation of the associated systemic disease, whereas obsessive-compulsive behavior is probably the main cause in the girl with EDS.

Enzymes of human cervical mucus: a comparative study on fertile and infertile mucus and on the endocervical epithelium.

We report a comparative study on protein and enzyme content of human periovulatory cervical mucus and endocervical epithelium. The salient results of our investigation are summarized in the following three points: 1) The method of taking of cervical mucus samples may markedly affect the results of protein and enzyme assays. It is warmly advisable to collect mucus samples from the endocervical canal. 2) Cervical mucus from women diagnosed as having cervical-factor infertility is oligoproteic and lacks some enzyme activities always present in normal cases. 3) Human cervical mucus and endocervical epithelium are very similar as for the enzyme distribution, but show quite different LDH-isoenzyme patterns. In the latter tissue, the H subunits constitute about 77 per cent of the whole LDH, suggesting that this enzyme here is functioning to produce pyruvate rather than lactate.

Changes in enzyme levels in human cervical mucus during the menstrual cycle.

Cervical mucus is a complex secretion produced by the endocervical epithelium. A comparative analysis of 30 enzymes was carried out on 15 women during their periovulatory period (days 10 to 16 of the menstrual cycle). Nine different enzymes were always found to be present in the cervical mucus. Changes in enzymatic activity were further studied in two of the women, one with a normal (27-day) and the other with a short (20-day) menstrual cycle. The data were compared with those for the same enzymes in the saliva of these two women. Each woman's ovulation time was determined through hormone measurements in urine and blood, as well as by recording basal body temperature and by Billing's method. Our results indicate that a maximum peak occurs for several enzymes during the periovulatory period.
