A 4-year-old boy has had a solitary sclerotic depressed plaque on the right anterior chest since birth. The histopathologic findings are consistent with morphea profunda: thickening, hyalinization, and homogenization of collagen bundles in the dermis and subcutaneous tissues, admixture with a prominent lymphocytic and plasma cell infiltrate, and sweat glands en-trapped between the thickened collagen bundles. We report a case of congenital solitary morphea profunda.

BACKGROUND: It is now thought that the earliest manifestation of idiopathic pulmonary fibrosis is alveolitis, that is, an accumulation of inflammatory and immune effector cells within alveolar walls and spaces. Inflammatory cells including alveolar macrophages and resident normal pulmonary tissue cells participate through the release of many variable mediators such as inflammatory growth factors and cytokines, which contribute to tissue damage and finally cause chronic pulmonary inflammation and fibrosis. This study was performed to investigate the source and distribution pattern of transforming growth factor-beta1(TGF-beta1), platelet derived growth factor(PDGF), basic fibroblast growth factor(bFGF), interleukin 1(IL-1), interleukin 6(IL-6), tumor necrosis factor-alpha(TNF-alpha) and the role of these mediators on bleomycin(BLM)-induced pulmonary injury and fibrosis in rats. METHOD: Wistar rats were divided into three groups(control group, BML treated group, BML and vitamine E treated group). Animals were sacrifices periodically at 1, 2, 3, 4, 5, 7, 14, 21, 28 days after saline or BLM administration. The effects were compared to the results of bronchoalveolar lavage fluid analysis, light microscopic findings, immunohistochemical stains for six defferent mediators(TGF-beta1, PDGF, bFGF, IL-1, IL-6 and TNF-alpha) and mRNA in situ hybridization for TGF-beta1. RESULTS: IL-1 and IL-6 are maximally expressed at postbleomycin 1~7th day which are mainly produced by neutrophils and bronchiolar epithelium. It is thought that they induce recruitment of inflammatory cells at the injury site. The expression of IL-1 and IL-6 at the bronchiolar epithelium within 7th day is an indirect evidence of contribution of bronchiolar epithelial cells to promote and maintain the inflammatory and immune responses adjacent to the airways. TNF-alpha is mainly produced by neutrophils and bronchiolar epithelial cells during 1~5th day, alveolar macrophages during 7~28th day. At the earlier period, TNF-alpha causes recruitment of inflammatory cells at the injury site and later stimulates pulmonary fibrosis. The main secreting cells of TGF-beta1 are alveolar macrophages and bronchiolar epithelium and the target is pulmonary fibroblasts and extracellular matrix. TGF-beta1 and PDGF stimulate proliferation of pulmonary fibroblasts and TGF-beta1 and bFGF incite the fibroblasts to produce extracellular matrix. The vitamine E and BLM treated group shows few positive cells(p<0.05). CONCLUSION: After endothelial and epithelial injury, the neutrophils and bronchiolar epithelium secrete IL-1, IL-6, TNF-alpha which induce infiltration of many neutrophils. It is thought that variable enzymes and O2 radicals released by these neutrophils cause destruction of normal lung architecture and progression of pulmonary fibrosis. At the 7~28th day, TGF-beta1, PDGF, bFGF, TNF-alpha secreted by alveolar macrophages sting pulmonary fibroblasts into proliferating with increased production of extracellular matrix and finally, they make progression of pulmonary fibrosis. TNF-alpha compares quite important with TGF-beta1 to cause pulmonary fibrosis. Vitamine E seems to decrease the extent of BLM induced pulmonary fibrosis.

Pruritic folliculitis of pregnancy of pregnancy is a specific dermatoses of pregnancy which is characterized by erythematous follicular papules and pustules between the fourth and ninth month of pregnancy. It has usually resolved by 4 weeks of postpartum and has no adverse implications for mother and baby. We report a case of pruritic folliculitis of pregnancy in a 24-year-old primigravida woman who had had monomorphic erythematous follicular papules and pustules on her anterior chest wall and back. Histopathological findings of erythematous papules showed acute folliculitis and perifolliculitis. The skin lesions improved rapidly with 2 weeks of delivery without treatment.

BACKGROUND: Topical irritants disrupt the cutaneous permeability barrier through the removal of stratum comeum lipids. This perturbation of barrier integrity stimulates a variety of homeostatic repair responses that ultimately result in the normalization of bamer function. Object To measure the effect of desoxymethasone ointment, vaseline and hydrobase on the barrier recovery of benzalkonium chloride (BKC) imtated skin. MATERIALS AND METHODS: The left flank skin of 2-3 monthold hairless mice was treated with BKC and then desoxymethasone ointment, vaseline and hydrobase were applied. Transepidermal water loss (TEWL) was checked after 0, 3, 6, 9, 12, 15, 18, 21 and 24 hours. Electron microscopic examination was performed after 3 and 24 hours after desoxymethasone, vaseline and hydrobase had been applied. RESULTS: The recovery of TEWL was most prominantly observed in the desoxymethasone ointment treated group followed by vaseline and hydrobase. Electron microscopic examination using ruthenium tetroxide fixation revealed that secretion and numbers of lamellar bodies and complete formatice of lipid bilayers were most prominent at desoxymethasone ointment and vaseline treated group. CONCLUSION: Desoxymethasone ointment, vaseline and hydrobase can be good agents in improving bamer recovery after exposure to irritant material.

9.A Case of Coexisting Neuromyelitis Optica in Systemic Lupus Erythematosus.
Journal of the Korean Ophthalmological Society 2013;54(9):1469-1474
PURPOSE: We present a case of a patient with coexisting neuromyelitis optica and systemic lupus erythematosus (SLE). CASE SUMMARY: A 26-year-old female was hospitalized in our medical center due to decreased visual acuity in her left eye; she had a history of gastric ulcers and herpes zoster infection. Steroid treatment was started under suspicion of optic neuritis, and she was diagnosed with SLE. After treatment, her vision improved, but eleven months later she was hospitalized with paresthesia on the abdomen and left flank progressing to the lower extremities. Spinal MRI showed transverse myelitis, suggesting multiple sclerosis. Fifteen months later, the patient was hospitalized due to decreased visual acuity and ocular pain in the right eye. Her vision was improved by steroid therapy. However, optic neuritis recurred in the right eye after five weeks, thus azathioprine was added to the treatment. Anti-aquaporin-4 Ab test was conducted based on the suspicion of neuromyelitis optica, and the serum was positive for anti-aquaporin-4 Ab (NMO-IgG). The patient was hospitalized again due to paraplegia after three months. Coexistence of neuromyelitis optica was verified because spinal MRI showed longitudinally extensive transverse myelitis. The symptoms were improved by high doses of steroids, a series of plasmaphereses, and rituximab. Optic neuritis was repeated in the right eye and the symptoms were improved with high doses of steroids. Myelitis recurred later and the symptoms improved with high doses of steroids and a series of plasmaphereses. CONCLUSIONS: Coexisting neuromyelitis optica should be considered in cases with relapsing events which have transverse myelitis without cranial lesions in autoimmune diseases such as SLE.

Korean Journal of Aerospace and Environmental Medicine 2004;14(3):105-108
BACKGROUND: The multicomponent cognitive-behavioral group treatment program is an effective treatment for fear of flying (FOF). In Korea, the effect of this treatment has not yet been studied. This is a preliminary study to assess the program's effect for Koreans with FOF. METHODS: Among 11 patients who participated in the treatment program, 10 completed the program, and data of 9 patients were obtained. Patients participated in individual treatment phase by diagnosis and symptoms, and in the group treatment phase for 2 days, composed of education on flight and anxiety, relaxation technique, cognitive reconstruction, imaginary exposure, mock-up treatment, real flight, etc. Flying history, Visual Analogue Flight Anxiety Scale (VAFAS), Flight Anxiety Situation Questionnaire (FAS) with 3 subscales (generalized, anticipatory, in-flight), Flight anxiety Modality Questionnaire (FAM) with 2 subscale (somatic, cognitive) were assessed before treatment and at 3 months after completion of the program. RESULTS: 8 patients made flights within 3 months after treatment. VAFAS, FAS total, 3 FAS subscales, FAM, and 2 FAM subscales were all decreased significantly after treatment. CONCLUSION: This results suggest that the multicomponent cognitive-behavioral group treatment program is effective for Koreans with FOF.
