Nickel sensitivity is the most common cause of allergic metal dermatitides,, particularly in women. Women are uaually sensitized. by the objects wom close to the skin ('e.g. earring, necklace fasther, watch, suspenders, brassiere clips, etc.), and men are by occupational exposures (e.g. plating or printing industries, tools, etc.). Nickel dermatitis is frequently developed on the sites where seems to have been directly contact witb nickel substance, but secondary eruptions may develop on the areas where seems to have not been directly exposed to nickel, so that nickel dermatitie is sometimea misdiagnosed as atopic dermatitis, nummular eczema, stasis dermatitis, or other dermatitides. The authora prcsent two cases of nickel dermatitis confirmed by patch test with 2. 5% nickel sulfafte; first case-a 22 years old female who has erythemat,ous maculopapular patches on her ears, around neck, left wriat, elbows, and abdomen; second case tkat was previously misdiagnosed as mummular eczema-a 18 years old female who has large oozing and crusted patches on both lateral aspects of her right thigh and back, The authors reviewed the incidence of nickel sensitivity during past years in korea and the clinical aspect of distribution of nickel dermatitis.

Idiopathic small bowel ulceration occurring beyond the duodenum is rare, and less than 5% of all the reported cases have occurred in children. In most of the cases, single ulcer of unknown cause is observed in jejunum or ileum. The diagnosis is difficult and usually made at the time of surgical exploration for the complications, such as perforation, hemorrhage or obstruction. We experienced a case of perforation of idiopathic ileal ulceration due to blunt abdominal trauma in a 11-year-old boy. The ileal segment including the lesion was resected and the pathologic findings were compatible with idiopathic small bowel ulceration. The clinical and pathological aspects are discussed, and the literatures were reviewed.

Acute infarcts of the anterior inferior cerebellar artery (AICA) territory are unusual. Furthermore incomplete AICA infarcts are perplexing because of its variations of vascular anatomy and inconsistent clinical features. We present a case with clinical features of AICA infarction, which consist of ipsilateral peripheral-type facial palsy, vertigo, and contralateral facial and upper limb sensory changes without motor weakness. The patient had hypertension and was a current smoker. The high signal intensity on inferior pontine tegmental area was found on MRI and the R2 interneuronal dysfunction was note on Blink reflex. The angiographic findings didn't show any focal vascular lesions, which is contrary to the pathogenesis of AICA infarction published previously. On the clinical ground, the present case reserves to attention in that patients with peripheral-type facial palsy should be properly evaluated and with thorough neurological examination and we could differentiate between the incomplete AICA infarcts such as Gasperini syndrome and Bell's palsy.

OBJECTIVE: Closure of a low transverse cesarean incision with one layer and two layer, we compared operative time, hemostasis, blood loss and postoperative sonohysteroperitoneographic findings. Study design: At our hospital 103 women were randomized to closure of a low transverse cesarean incision with either one continuous layer of a locking No. 1 chromic suture or two continuous of No. 1 chromic suture with the first layer locked between Mar. 1, 1998 and Dec. 31, 1998. After three months later, sonhysteroperitoneography was taken and then we evaluated uterus indirectly. RESULTS: A one layer closure required less operative time, 16 versus 20.8 minutes (p<0.01), less hemoglobin change, 0.44 versus 1.3 (p<0.01) and less suture materials (p<0.01). But postoperative follow up sonohysteroperitoneography, a one layer closure shows slightly thinning of isthmic layer of myometrium, two layer closure shows more adhesional band and both are similar other findings. CONCLUSION: A one layer does not significantly affect the clinical course than traditional two layer closure. So we recommended a one layer closure when its use is anatomically feasible.

The malignant fibrous histiocytoma (MFH) was first introduced in 1963 to refer to a group of soft-issue tumors characterized by a storiform or cartwheel-ike growth pattern and predominantly fibroblastic appearance. It was postulated that they were derived from histiocytes that could assume the appearance and function of fibroblasts. MFH has been recognized to be the most common sarcoma in the soft tissue of late adult life which involves the deep fascia or skeletal muscles of the extremities or retroperitoneum. It has been noted in other organs, however, it rarely arises in the liver. We report two cases of primary malignant fibrous histiocytoma of the liver histopathologically confirmed after surgical resection-storiform pleomorphic and myxoid subtypes in the 55 year old male and 49 year old female patients, respectively, and describes the clinical courses, characteristics and pathologic aspects with review of the related literatures.

BACKGROUND: Solvents play an immense role in the industria sector. Irritant dermatitis which is more common than allergic contact dermatitis can be caused by solvents. OBJECTIVE: Our purpose was to compare the skin irritancy of several solvents using human and guinea pig skin models. METHODS: The skin responses to short contact with etharol, acetone, dimethylsulfoxide (DMSO) and xylene were measured by visual scoring of erythm, transepidermal water loss and laser doppler flowmetry. RESULTS: The results are summarized as follows . 1. Guinea pig and human skin responses to normal saline, ethanol, and acetone were nearly negligible. 2. Guinea pig skin responses to 99.9% DMSO under occlusion for 0.5 min were assessed by visual scoring system, TEWL, and LDF. They are measured 3+0.(0,1+21.70, 45+12.70 at 5 min after removal of 99.9% DMSQ, and 0.83+0.41, 10.5+3.83, 36+4.0, to 120 min after removal. 3. Guinea pig skin responses to 97% xylene under occlusion for 5 nin were assessed by visual scoring system, TEWL and LDF. They are measured 3+0.00, 1. 5.82, 77+11.7 at 5 min after removal of 97% xylene, and 1.83+0.75, 5.5+3.21, 39.17+11.53 at l2 min after removal. 4. Human skin responses to 75% DMSO under occlusion for 1 min were assessed by visual scoring system, TEWL and LDF. They are measured 2,5+0.5, 63+25.8, 51+13.7 at 5 min after removal of 75% DMSO, and 0.17+0.41, 14.67+15.87, 21.17-8. 1 at 120 min after removal. 5. Human skin responses to 97% xylene under occlusion for 12 min were assessed by visual scoring system, TEWL and LDF. They are measured 2.7+0.52+4.22, 76+14.30 at 5 min after removal of 97% xylene, and 0+0, 2.5+0.55, 3.17+0.98, 120 emOVBI. CONCLUSION: Short contact vrith DMSO and xylene cause visib erythema and an increase in TEWL and cutaneous blood flow. The reaction patterns in hurr an and guinea pig skin models were similar.
