Perception of Child Abuse and Child Disciplinary Practice among Adults Abused as Children: Comparison to General Population

OBJECTIVES: The aim of this study was to compare differences in perception and knowledge of child abuse and child disciplinary practices according to the history of child abuse victimization. METHODS: A questionnaire survey on child abuse was conducted with 491 adults raising children. We compared the perception and knowledge of child abuse and child disciplinary practices between two groups of adults with and without a history of childhood abuse victimization. RESULTS: The group with a history of childhood abuse had lower levels of knowledge of child abuse (F=6.990, p<0.01) and engaged in more negative disciplinary practices (F=5.974, p<0.05) than those without. However, no differences in the perception of child abuse were observed between the two groups. CONCLUSION: The results suggest that adults with a history of childhood abuse have lower levels of knowledge of child abuse and use more negative disciplinary practices in raising their children. This highlights the need to administer not only educational but also more direct hands-on interventions to vulnerable parents in order to foster healthy parenting and disciplinary practices.

A Case of Hobnail Hemangioma / 대한피부과학회지

Hobnail hemangioma, also known as "targetoid hemosiderotic hemangioma", represents a distinctive benign vascular tumor, characterized histologically by a biphasic growth pattern of dilated vascular structures lined by prominent hobnail endothelial cells in the superficial dermis, and collagen dissection by angulated vessels in deeper parts of the lesion. It is important to distinguish this tumor from patch stage Kaposi's sarcoma, retiform hemangioendothelioma and progressive lymphangioma. We report a 26-year-old man showing typical clinical and histological features of hobnail hemangioma.

Patch testing in Atopic and Non-Atopic Dermatitis / 대한피부과학회지

BACKGROUND: The frequency and importance of contact allergy in patients with atopic dermatitis(AD) have been debated. Although the study about patch test in AD is common in foreign countrles, it is rare in our country. OBJECTIVE: We performed this study to examine the patch test in patients with AD and to know the frequency of contact sensitization and the correlation between metal allergy history and patch test reaction to nickel in patients with AD and non-atopic dermatitis(NAD) METHODS: One hundred nine patients with AD and one hundred twelve patients without AD were patch tested and questioned about history of metal allergy. RESULTS: 1. The contact sensitivity rate in AD was higher than NAD by 85.3%, 72.3% respectively. But there was statistically no significant difference in the two groups. 2. Positive contact allergens in all patients were cobalt, chromate, nickel, thimerosal, mercury. 3. Positive contact allergens in AD were cobalt, nickel, potassium, thimerosal, formaldehyde, neomycin and in NAD were cobalt, chromate, nickel, mercury, fragrance mix, 4-phenylenediqamine base. 4. The frequency of metal allergy history in all patients was 29% and it was 37.6% in AD and 20.5% in NAD. 5. Patients with metal allergy history had higher positive rate to nickel than patients without metal allergy history. 6. Patients with metal allergy history and AD had higher positive rate to nickel than patients with metal allergy history and NAD. 7. Patients who were positive to nickel were also positive to cobalt, chromate. CONCLUSION: This study shows that contact sensitivity is relatively common in AD, and metals including nickel are important allergens in AD. Therefore when the symptoms of AD are aggravated, it is important to perform the patch test, considering the possibility of contact dermatitis.

Giant cell tumor of tendon sheath on the fingertip / 대한피부과학회지

Giant cell tumor of tendon sheath is a benign histiocytic proliferation of the articular and peritendinous synovial tissue and manifests as a painless, firm, smooth, subcutaneous mass which occurs predominantly on the hand where it is typically located adjacent to the interphalangeal joints of the hands, especially the terminal interphalangeal joints. Histologically, it is characterized by the presence of multinucleated giant cells. We herein report a case of giant cell tumor of tendon sheath located on the fingertip with the involvement of overlying skin, which shows rare location and unusual clinical manifestation.

Multiple Cutaneous Focal Mucinosis with Widespread Skin Lesion / 대한피부과학회지

Cutaneous focal mucinosis is a condition with an asymptomatic, small, dermal, white to flesh-colored papule with a predilection for the face, neck, trunk, and extremities. This is usually presented as solitary lesion but rarely as multiple papules or nodules. Histologically, a localized area of the collagen in the upper dermis is largely replaced by homogenous mucinous material in which spindle-shaped fibroblasts are scattered. We report a case of cutaneous focal mucinosis which was presented as multiple lesions covering widespread skin lesion throught the face, chest and back.

A Case of Dyskeratosis Congenita

Dyskeratosis congenita is a rare genodermatosis of ectodermal dysplasia, which is characterized by the diagnostic triad consisting of reticulated hyperpigmentation, dystrophic nails, and leukoplakia. There is a predisposition to malignancy, particularly at sites of leukoplakia. Bone marrow failure can occur in about a half of the cases. A 16-year-old boy was presented with asymptomatic reticulated pigmentation of the neck and nail dystrophy. The patient also had leukoplakia on the tongue, nasolacrimal duct obstruction and cataract. The histopathological findings taken from the reticulated lesion were consistent with poikiloderma atrophicans vasculare. These clinical and histopathological findings were typical features of dyskeratosis congenita.

Lipoid Proteinosis / 대한피부과학회지

Lipoid proteinosis is a rare autosomal recessively inherited disorder that is characterized by the deposition of hyaline-like material in the skin, oral cavity, and other organs. Microscopically, there is extensive deposition of amorphous eosinophilic material surrounding capillaries, sweat glands and in papillary dermis. Although the pathogenesis of this disease is not well understood, it is believed that it may result from the defect of collagen metabolism leading to abnormal accumulation of noncollagenous glycoprotein. We report a case of lipoid proteinosis in a 20-year-old female that demonstrates the characteristic clinical, histopathological, and ultramicroscopic features of this disease.

Hand-Foot Syndrome with Nail Changes Induced by Fluorouracil / 대한피부과학회지

Many chemotherapeutic agents induce both local and systemic cutaneous toxicity. Among them, Fluorouracil (5-FU) induces various cutaneous reaction, including hand-foot syndrome, hypersensitivity, hyperpigmentation and nail changes. We describe a male patient with rectal cancer, who developed combined features of hand-foot syndrome and nail changes during chemotherapy with 5-FU.
