Striae distensae-like lesions. A cause of scarring alopecia among children.
OBJECTIVE: Although alopecia areata is a common problem among children, many misdiagnoses for this condition can happen. The aim of this study was to demonstrate the striae distensae as lesions that cause scarring alopecia with a great resemblance to alopecia areata. METHODS: A total of 36 children with provisional diagnosis of alopecia areata of the scalp were assessed clinically in the Department of Dermatology and Venereology, Baghdad Teaching Hospital, Baghdad, Iraq, between June 1998 to June 2001. Their age ranged from 3 12 years and the mean + standard deviation (SD) was 7.30 + 2.59 years with equal sex ratio. RESULTS: All patients provided for this study had a history of patchy hair loss of few months duration. Their parents denied any history of obvious trauma and many modalities of treatment had been tried without benefit. The clinical examination revealed single or multiple (1-6) (mean + SD 2.41 + 1.22) complete linear hair loss patches resembling atrophic scar that was similar to striae distensae. The histopathological examination showed atrophy of the epidermis, full replacement of the dermis by collagen bundles, and complete loss of appendages. CONCLUSION: This is a new entity, which seems to be common among children and often confused with untreated cases of alopecia areata. This condition should be added to the differential diagnosis of patchy hair loss in children and the parents should be reassured of the cause of hair loss and no treatment therapy needed.
[Mechanical behavior of fibroblasts included in collagen lattices].
Striae distensae are characterized by linear, smooth bands of atrophic-appearing skin. Excessive steroid activity, genetic and mechanical factors and inherited defects of connective tissues are the most frequent causes of this disease. Fibroblasts derived from women presenting striae distensae lesions were included into collagen gels to study their mechanical behavior: capacity to contract free-floating lattices and to produce isometric force in tense lattices. To measure the retracted lattice diameter, the culture dishes were placed on a transparent metric scale. An isometric force system was used to study quantitatively the forces developed during lattice contraction. alpha 2 beta 1 integrins expression (transmembrane receptors) was evaluated by flux cytometry. Striae distensae fibroblasts contract collagen gels slower than normal human fibroblasts but the final contraction is similar. They produce a greater isometric force which is associated with enhanced alpha 2 beta 1 integrins expression. By their mechanical properties, striae distensae fibroblasts appear as a different population from normal fibroblasts.
An overview of dermatological conditions commonly associated with the obese patient.
Obesity is a chronic disease that may lead to skin problems, including acanthosis nigricans, skin tags, hyperandrogenism, striae distensae, plantar hyperkeratosis, and candidal intertrigo. Although some conditions (eg, skin tags and striae distensae) may simply be annoying or present cosmetic issues, conditions such as acanthosis nigricans and hyperandrogenism may be indicative of systemic diseases. Obesity also may contribute to poor healing of acute and chronic wounds that develop in this population. Some of the most common obesity-related skin disorders and factors affecting wound healing are described with suggestions on how to address these issues. With the continuing increase in the incidence of obesity, investigation into the specific care needs of this population is needed. In clinical practice, measures to reduce friction and shear and improve devices to move the obese patient would enhance care provision. Studies of the incidence of dermatological problems and the best treatments for these conditions are warranted.
[Attempt of preventive treatment of striae gravidarum using preventive massage ointment administration].
Striae distensae are an appreciable cosmetic problem for many pregnant women. Preventive application of a water/oil massage cream was tested in a group of 24 gravidae (control group: 26 patients). In the untreated control group striae distensae were observed in two-thirds of the patients, whereas the prophylactically-treated gravidae showed development of striae in only one third of the group given the test preparation. Better results were obtained in women with a favourable constitutional predisposition than in patients with a tendency to overweight. The massage cream was well tolerated by all gravidae.
Anatomy of striae.
The histopathology of striae distensae is disputed; different authorities give contradictory accounts of the microscopic changes, especially in elastic fibres. We re-evaluated the problem by taking eight elliptical biopsies across striae. Six were examined by light microscopy with appropriate stains for elastin and collagen. Two were prepared for scanning electronmicroscopy (s.e.m.), using a procedure which removes collagen, enabling the elastic network to be seen in its native form. By light microscopy, striae were sharply demarcated from normal skin, consisting mainly of fine, straight bundles of collagen arranged parallel to the surface. Fine elastic fibres were disposed similarly without fragmentation, fraying or curling. By s.e.m., the elastic network was found to be extraordinarily dense and well developed with many fine, curled fibres in random array. It was evident that the routine stains for elastin greatly underestimated the abundance of elastic fibres, probably because immature fibres contain insufficient protein matrix. The horizontal packing of collagen bundles was confirmed by s.e.m. These findings support the view that striae distensae are scars. There is no evidence that they form by stress-induced rupture of the connective tissue.
Laser therapy of stretch marks.
Striae distensae, better known as stretch marks, are a common disfiguring skin disorder of significant cosmetic concern. Many sources have reported the use of lasers to diminish the appearance of striae. Controlled clinical studies of the various treatment modalities available for striae are relatively uncommon, and much of the clinical data are anecdotal. The use of lasers alone or in combination with other therapeutic modalities can provide a safe and effective reduction in the appearance of both red and white striae distensae. Many of these therapies require special measures for darker skin phototypes. This article reviews the historical use of laser therapy for this disorder and discusses current therapeutic options.
Prevalence of skin diseases among adolescents 12--16 years of age.
A prevalence study of 8298 pupils in compulsory school grades 7--9 was performed in the county of Västerbotten (AC county) in northern Sweden. Prevalence figures for 19 skin diagnoses are presented. A female dominance was found in the prevalence of atopic dermatitis, striae distensae and plantar warts, and a male dominance in multiple pigmented naevi. A sharp drop in atopic dermatitis was found at 13 years. Acne vulgaris showed a negative correlation with atopic dermatitis, ephelides, multiple pigmented naevi and spider naevi and a positive correlation with striae distensae. Atopic dermatitis was negatively correlated to ephelides and multiple pigmented naevi as well as acne. Pronounced variations in the occurrence of plantar warts were registered between different schools. Of the 19 diagnoses registered, only hereditary palmo-plantar keratodermia has a geographical distribution compatible with an increased prevalence of the disease in the AC county. Consequently the figures presented for the other diagnoses are considered to be representative for a north European Caucasian population.
