A study was conducted to provide comprehensive information in epidemiological state of crippled schoolchildren in Chungnam area from November 23, 1979 to 19, 1980. In this study, two step survey was conducted upon whole primary, middle and high school, and subsequent selected 537 case in total 3,063 crippled children. The results obtained are as follows; 1. The prevalence rate of orthopedic defect children was 3.7 per 1,000 and dominant male as 6 : 4. 2. It was relatively high the school grade and prevalence rate more increased. Prevalence rate was highest in high school as 4.7 per 1,000, middle in middle school as 4.4 per 1,000 and lowest in primary school as 3.1 per 1,000. 3. The most predominant group was 15-19 age as 52.9 percent. 4. The most common job of their parent was agriculture as 52.9 percent and next job sales and service. Economic state of Cripple's parent have revealed no particular difference. 5. In a family, the most common incidence rate was first children in both sex and decreased by ordered sibling. 6. Poliomyelitis was the most common cause as 71.5 percent and next cerebral palsy 11.9 percent. 7. The most common affected sited was lower extremity (Right: 42.3%, Left: 35.5%) and next upper extremity. Right was more dominant as 55:45. 8. Intelligence was decreased in cerebral palsy predominantly than other cause of defect, including poliomyelitis. 9. For the treatment of their condition at onset of illness, crippled children was utilized private clinic and herb medicine, but was changed tendency of treatment as acupuncture and moxibustion after diagnosis of cause defect.

Keratosis punctata of palmar creases has been considered an uncommon variant of keratosis punctata, which itself is considered rare condition. Clinically our case, 32-year-old seaman, shows cup-shaped depression of the epidermis of varying size, from 1-3mrn in diameter, limited to the large flexor creases of the palms and digit. The histologic features are hyperkeratotic and slight acanthotic central epidermal depression without parakeratosis and loss of granular layer. A sparse mononuclear infilterate are seen arround the capillaries in the dermal papillas. No relationship to arsenical agents, syphilis, or genetic factors can be ascertained by history.

Incontinentia pigmenti is an uncommon genodermatosis. It affects female infants predominantly, described first by Bardach in l925, with the diagnosis of systematized nevus and Bloch in 1926, and Sulzberger in 1928 rnore compIetely. Skin lesions are characterized by 3 stages such as vesicobullous, verucous and finally pigmentary lesions and leave brownish pigmentation on the extremities and trunk. Hesides skin lesions some ectodermaI and mesodermal organs are affected and show developmental abnormalities. We experienced a case of incontinentia pigmenti in a 45-day-old female infant and present it with the review of literature. She showed extensive vesicobullopustular eruption with linear and reticular pigmentation on the extremities and trunk. Clinical and histopathologic findings of these lesions are compatible with Bloch-Sulzberger type of incontinentia pigmenti.

General information is summarized, that is necessary to introduce a scientific assessment of the human health and exposure issue concerning dioxin and dioxin-like compound. Scientific literatures were reviewed to assess the background exposures to the dioxin-like compounds for normal residents. Epidemiologic studies were also reviewed to assess malignant and nonmalignant effects of dioxins. In 1997, the International Agency for Research on Cancer classified 2, 3, 7, 8-tetrachlorodibenzo-p-dioxin (TCDD) as a human carcinogen, primarily based on occupational cohort studies. The US Environmental Protection Agency made the same decision in it's Draft Dioxin Reassessment. Epidemiologic evidences point to a generalized excess of all cancers, without any pronounced excess at specific sites. Reported non-cancer effects included a range of conditions affecting most systems. Among them, chloracne, elevation in gamma glutamyl transferase (GGT), and alterations in reproductive hormones are related to TCDD. Other adverse outcomes, such as lipid concentrations, diabetes, circulatory and heart diseases, immunologic disorders, neurobehavioral effects, and developmental outcomes require further study before their respective relationships to TCDD can be more definitively assessed.

BACKGROUND: Calcinosis cutis may occur when connective tissue is abnormal (dystrophic), or where calcium or phosphate levels in the blood are high(metastatic); alternatively, there may be no obvious underlying cause(idiopathic). The exact incidence of calcinosis cutis in dermatologic patients is not well-kniown and the pathomechanism of it remains to be elucidated. OBJECTIVE: This study was performed to analyze the incidence, clinical and histopathological features of calcinosis cutis. METHODS: We studied 72 patients with calcinosis cutis who visited our department between January 1985 and December 1996. The patients were classified into 3 types (dystrophic, metastatic, and idiopathic) and were analyzed clinically and histopathologically. Results : The results were summerized as follows; 1. There were 60 cases(83.3%) and 12 cases(16.7%) of the dystrophic and idiopathic types, respectively but the metastatic type was not observed. The frequency of dystrophic calcification in individual disorders was 88.2% in pseudoxanthoma elasticum, 66.7% in trichilemmal cyst and dermatomyositis, and 64.6% in pilomatrichoma. 2. In the idiopathic type, it was common in females aged over 50 years and the mean duration of lesions was 2.8+/-2.0 years. The predilection site was the flank(5 cases) and most of the lesions(7 cases) showed skin-colored nodules 3. Histopathologically, calcified material of the idiopathic type was located predominently in the dermis(10 cases) and was present as large masses surrounded by a foreign body reaction. 4. In the dystrophic type, calcified deposits were noted predominently within the shadow cells of pilomatricoma, in the degenerated elastic fibers of pseudoxanthoma elasticum, and in the keratinized area of basal cell carcinoma, squamous cell carcinoma, trichilemmal cyst, and epidermal cyst. Foreign body reactions with giant cells and mononuclear cell infiltrations were often found around large deposits of calcium. Conclusion : The incidence of calcinosis cutis in dermatologic patients is relatively low, but a variety of disorders can be associated with cutaneous calcification. Therefore, dermatologists should be familiar with the different forms of cutaneous calcification and the dermatoses that manifest them.
