Injectable collagen: a clinical overview.

Injectable bovine collagen is extremely effective in the correction of contour defects of the skin due to scarring and age-induced rhytides and folds. The rate of adverse reactions is low. Of 5,109 patients treated in clinical trials, 1.3 percent experienced temporary local inflammation at the site of injection. Techniques of injection and proper patient selection are presented. Repeat implantations at intervals of six to twenty-four months are often required to maintain full correction of cutaneous contour defects.

Estimation of gestational and skeletal age in Macaca mulatta.

Results of qualitative and quantitative studies of prenatal skeletal development in Macaca mulatta are presented. Longitudinal radiographic observations were carried out on 20 monkeys of known gestational age, beginning on 120 days of gestation until the neonatal stage of skeletal development. These studies were based on multiple uterotomies on each pregnant female. The technique described provides accurate data on prenatal bone ossification, and permits an accurate estimation of fetal age in pregnant rhesus monkeys with unknown conception dates.

Kaposi's varicelliform eruption in mycosis fungoides.

Kaposi's varicelliform eruption, caused by herpes simplex type 1, developed in a patient with mycosis fungoides four days after initiation of photochemotherapy with methoxsalen plus long-wave ultraviolet light (PUVA). He had a history of recurrent localized herpes infection. Vidarabine (adenine arabinoside) was used as treatment. Rechallenge with PUVA did not provoke another herpes infection. Kaposi's varicelliform eruption is rare in mycosis fungoides. Vidarabine may prove to be useful in the treatment of widespread herpes simplex.

Coexistent psoriasis and bullous pemphigoid: a report of six cases.

Vesicles and bullae developed in six patients with psoriasis while they were undergoing therapy for their psoriasis. Skin biopsy specimens were taken from their lesions and studied for regular histopathologic findings and direct immunofluorescence. These studies confirmed that they had coexistent psoriasis and bullous pemphigoid. A review of the therapy that the patients were given incriminates anthralin, crude coal tar, ultraviolet light, and salicylic acid in the possible cause of the development of their bullous pemphigoid lesions.

Methotrexate toxicity in the treatment of generalized pustular psoriasis.

In a sixty-seven year old woman with a seventeen-year history of psoriasis, generalized pustular psoriasis of von Zumbusch developed. She was treated with parenteral methotrexate in two divided doses over a one-week period. Severe acute granulocytopenia developed with a drop in the white blood cell count from 27,000 to 400. We postulate that the pustular psoriasis stimulated rapid proliferation of the granulocyte series with a high percentage of the precursor cells in the bone marrow in the S-phase of the cell cycle. The subsequent dose of methotrexate resulted in a blockage of DNA synthesis in these cells and subsequent failure of maturation beyond the mitotic compartment in the bone marrow. Caution is recommended in the use of methotrexate in patients with acute generalized pustular psoriasis.

Fungal infections of the skin in children.

Fungal infections of the skin in children are common and may mimic many other dermatoses. Diagnostic techniques are simple and inexpensive; Wood's light examination, KOH wet mounts, and preferably fungal culture should be performed on all suspected lesions.

Screening for skin cancer at a county fair.

Six skin cancer detection clinics were held at a county fair booth in Turlock, California during August, 1973. Examination of sun-exposed skin areas in 605 people showed potential skin cancer in 28.6 percent of people 25 years of age or older. Of the people examined, 135 were referred to their own physicians for follow-up diagnosis and treatment of skin lesions.
