Parental smoking and passive smoking in infants: fathers matter too.

This study examines mothers' and fathers' smoking patterns in different kinds of smoking households, and assesses their relative contribution to infants' exposure to environmental tobacco smoke. It uses data from a cross-sectional survey of 314 smoking households (infants: mean age 10 weeks) in Coventry and Birmingham, England, examining reported tobacco consumption and objective measures of exposure: the study infant's urinary cotinine:creatinine ratios and their mother's salivary cotinine. The study shows that both mothers' and fathers' tobacco smoke make substantial contributions to infant exposure to tobacco smoke. Households were more likely to contain a smoking father than mother, with over two-thirds of households including a smoking father. In households where both parents smoke, fathers' tobacco consumption was found to be significantly higher than in households where only the father smokes. This suggests that the interaction between parents needs to be considered rather than focusing on mothers' or fathers' smoking behaviour in isolation. The implications for health promotion programmes are discussed, particularly the need to place more emphasis on tackling fathers' smoking. Currently, fathers' smoking receives far less research or health promotion attention than mothers' smoking. Protecting infants from fathers' as well as mothers' smoking is key to reducing environmental tobacco exposure in early infancy, when the risk of Sudden Infant Death is highest.

Occlusive dressing versus oxygen mist therapy following CO2 laser resurfacing.

BACKGROUND: Oxygen is an essential element for collagen synthesis and reepithelialization. The use of topical oxygen after CO2 laser resurfacing has not been studied. OBJECTIVE: To compare the rate and quality of healing in wounds treated with an oxygen mist to those treated with occlusive dressing following CO2 laser resurfacing. METHODS: Three patients underwent CO2 laser resurfacing to each half of the face 3 weeks apart. Postoperatively, half of the face was treated with an oxygen mist protocol for 5 days, while the other half was treated with occlusive dressing for 4 days. RESULTS: At postoperative day 5, significantly less crusting was observed on the half of the face treated with the oxygen mist protocol (p < 0.05). CONCLUSION: The oxygen mist postoperative protocol may offer patients similar overall healing rates and significantly less crusting compared to occlusive dressing.

A clinical study of hair removal using the long-pulsed ruby laser.

BACKGROUND: Laser hair removal is rapidly becoming a widely used modality. Clinical studies are needed to assess these hair removal systems. The long-pulsed ruby laser is one such modality for the removal of unwanted hair. OBJECTIVES: To evaluate the efficacy of the long-pulsed ruby laser (694 nm, 3-msec pulsewidth, 7- or 10-mm spot size) in removing unwanted hair, and to provide treatment guidelines for the proper utilization of this laser system. METHODS: Forty-eight areas of unwanted facial and body hair from 25 patients with blonde, brown, or black hair were treated with the long-pulsed ruby laser at fluences between 10 and 40 J/cm2. Hair regrowth was measured at 4 weeks after the first treatment, 4 weeks after the second treatment, 4 weeks after the third treatment, and 16 weeks after the third treatment by counting the number of terminal hairs compared with baseline pretreatment values. All complications and treatment outcomes were documented. RESULTS: The mean percent of regrowth after the first treatment was 65.5%, 41% after the second treatment, and 34% after the third treatment. Overall, regardless of skin type or targeted body region, patients who underwent three treatment sessions demonstrated an average 35% regrowth in terminal hair count compared with baseline pretreatment values 6 months after initial therapy. CONCLUSION: Long-pulsed ruby laser treatment resulted in significant hair growth delay in most cases. Repeated laser treatments produced an increased number of vellus hairs, an increase in growth delay, and a decreased percentage of hair regrowth.

Chronic bullous dermatosis of childhood. Linear iga bullous dermatosis.

A 21/2-year-old boy had large, tense bullae on the groin, buttocks, legs and abdomen. A subepidermal vesicle was seen on histological study. Immunofluorescent studies revealed linear IgA at the basement membrane zone. There was no associated gastrointestinal abnormality or any other systemic feature. The patient responded dramatically to sulfapyridine. He has had no recurrence of the disease and negative immunofluorescence study results during two years of follow-up.

Death in pemphigus.

Pemphigus is frequently a fatal skin disease. The cause of death and the events leading to it were investigated by examining patient records and autopsy data of thirteen patients who died as a result of this disease at the UCLA Hospital between 1965 and 1980. The diagnosis was confirmed histologically and/or by immunofluorescent studies of the skin and serum. Infection was the most frequent cause of death, and septicemia was found in nine of thirteen cases. The most commonly found organism was Staphylococcus aureus. The skin was usually the source of infection. Nine patients had pneumonia on chest x-ray and autopsy examination. Most patients had low levels of serum proteins and serum albumin. Since the patients were on long-term high doses of corticosteroids, the signs and symptoms of inflammation were often masked. This study demonstrated that for this reason, long-term corticosteroid therapy is one of the significant factors contributing to the death of these patients. A cautious and judicious use of steroids is suggested.

Carpet beetle dermatitis.

A 22-year-old man presented with a 5-year history of recurrent urticarial and papulovesicular lesions. Careful history suggested a close examination of his environment. The woolen rug in his bedroom was infested with larvae of a carpet beetle. The insect was identified as Anthrenus verbasci. Fumigation of the house with sulfuryl fluoride (Vikane) resulted in complete clinical recovery. Intradermal injection of the antigenic extract from the larvae showed a wheal and erythema on the patient's skin, and not on normal controls. This suggests that the patient had immediate-type hypersensitivity to some of the antigens extracted from larvae. Electron microscopic pictures of the insect are presented.
