BACKGROUND: The keratinocyte growth factor(KGF) is a recently identified mitogen for epithelial cells produced by nomal stromal fibroblasts. ln the skin, KGF has been shown to stimulate keratinocyte proliferation and differentiatian. Dendritic epidermal T cells(DETC) are skin-specific members of the epithelial y 8 T-cell family that reside normally in the murine epidermis. The DETCs recognize antigen expressed by damaged or diseased neighboring keratinoctyes and consequently secrete cytokines sueh as IFN- y, lL-2, IL-4, GM-CSF. OBJECTIVE: The purpose of this study was to observe the expression of KGF mRNA in keratinocyte and DETC as well as to investigate the cytokine-mediated intercellular communication between kerati- nocyte and DETC. METHODS: Using a RT-PCR(reverse transcription-polymerase chain reaction), we examined the expression of KGF mRNA in keratinocyte and DETC, and compared the level of KGF mRNA between resting and activated DETC with Con-A (concanavalin A).

2.Prepapillary Vascular Loops Associated with Retinal Diseases.
Journal of the Korean Ophthalmological Society 2001;42(7):1111-1116
PURPOSE: Prepapillary vascular loops are blood vessels that project from the optic disc into the vitreous cavity and then return to the disc to continue their natural cource. Ninety percent are arterial in origin and usually congenital anomaly. We report four cases of prepapillary vascular loops associated with retinal and choroidal disorders. METHODS: Prepapillary vascular channel which showed twisted or ringlike appearance without leakage on fluorescein angiogram constituted the diagnosis. However, there may be a sector delay in filling of the optic disc or retina supplied by the loop due to the increased distance that blood must travel through the loop. RESULTS: These cases are not associated with vision-threatening diseases. The associated retinal diseases are diabetic retinopathy in one case, retinitis pigmentosa in one case, contralateral posterior uveitis in two cases. They are arterial loops. In two eyes were observed multiple prepapillary vascular loops. The vessels may appear as simple hairpin loops, spiral, or corkscrew configuration. In our cases, the presence of a cilioretinal artery and retinal artery obstruction could not be determined; other complication associated with prepapillary vascular loops were not observed. CONCLUSIONS: We assume that prepapillary vascular loops may occur acquiredly associated with other ocular diseases.

Twenty-nail dystrophy is an idiopathic nail dystrophy in which all twenty nails are uniformly and simultaneously affected with excess longitudinal ridging and loss of lustre. The pathogenesis is controversial, and the treatment is unsuccessful. It is thought to have a self-limiting and reversible nature when it develops in childhood, but in adults, it is unusual and exists persistently. We re-port here two cases of adult patients with dystrophy of all twenty nails, whose ages were 58 and 55. The disease had been present for one year and may be associated with alopecia areata in the 58 year old and an idiopathic condition in the 55 year old. Negative results were obtained on mycological studies. Biopsies taken from the nail bed revealed marked hyperkeratosis consistent with nail dystrophy.

A case of a 21-year old female with Maffucci's syndrome is presented where the patient developed multiple cutaneous spindle-cell hemangioendotheliomas. She had multiple pea to walnut sized, non-tender, normal skin colored or slight bluish nodules and bony mass-like lesions on the left upper extremity and hand. A histological examination of the lesions showed that they were composed of irregularly dilated, thin walled cavernous blood spaces containing phleboliths and collapsed vascular spaces separated by spindled fibroblastic cells. Radiologically, the bony lesions showed radiolucent densities with calcified spots within the second proximal phalanx and metacarpal bone of the left hand, which were consistent with enchondromas.

We report a case of infantile digital fibromatosis in a 34 month-old boy, who presented with a painless subcutaneous tumor on the medial aspect of the left third toe. A histological examination showed scattered small, round eosinophilic inclusion bodies in the cytoplasm of the tumor cells, which was consistent with infantile digital fibromatosis. A'immunohistochemical study revealed that desmin, a-smooth muscle actin, and vimentin were clearly positive in the cytoplasm of the tumor cells, but the inclusions themselves showed negative staining, thus indicating a hollow-like staining pattern. Electron microscopy showed either well-defined or ill-demarcated dense bodies in the cytoplasm of the tumor cells. In some areas, small vesicles and intracellular organells were observed' in the inclusions. In the course of conservative treatment, a new lesion developed on the lateral aspect of the left third toe, seven months after the appearance of the initial lesion.

6.Prognostic Factors in Idiopathic Macular Hole Surgery.
Journal of the Korean Ophthalmological Society 2000;41(8):1746-1752
We evaluated the relationship between the surgical success of idiopathic macular hole and sex, age, duration, epiretinal membrane, preoperative visual acuity, size of the hole, and surgical method. Of all 25 eyes in 23 patients, 14 eyes(56%)showed anatomical success(disappearance of the hole), and 17 eyes(68%)functional success(the final visual acuity of 0.15 or more with more than one line improvement). There were statistically significant differences of anatomical(p=0.001)and functional success(p=0.020)between the Group I where its macular hole was less than one-fourth of the optic disc in size and the other group, and anatomical success(p=0.039)between the group with the age of less than 70 years(Group A)and the other group. In Group I, anatomical and functional success were both 92%(11 eyes/12 eyes). In Group A, anatomical and functional success were 72%(13 eyes/18 eyes)and 77%(14 eyes/18 eyes), respectively, and there was statistically significant relationship between size of the hole and anatomical success(p=0.024), and difference of anatomical success between the group with duration of less than 6 months and the other group(p=0.023). Good surgical result may be expected in the idiopathic macular hole of the age of less than 70 years with about 350 micrometer or less in size and duration of less than 6 months.

We report a case of disseminated cutaneous metastatic carcinoma from stomach carcinoma in a 66-year-old male who complained chiefly of widespread cutaneous nodules. He had been admitted to the Department of Internal Medicine for stomach carcinoma. A radiological examination revealed a diffuse stomach wall thickening from the fundus to the antrum, and enlargement of paraaortic and pericaval lymph nodes during an abodominal CT scan. The clinical findings manifested above may suggest cutaneous metastasis from stomach carcinoma. A histological examination of the skin and stomach biopsies showed atypical cells with pleomorphic, hyperchromatic nuclei and bubble-like cytoplasm, which are consistent with poorly differentiated adenocarcinoma. Immunohistochemical stainings showed that these cells were positive for epithelial membrane antigen (EMA), carcinoembryonic antigen (CEA) and low molecular weight cytokeratin.

Annals of Dermatology 1999;11(1):13-18
BACKGROUND: The regular use of soaps and synthetic detergents has been associated with skin dryness and aggravation of dermatological conditions. OBJECTIVE: Our purpose was to investigate the irritancy of 10 hand dishwashing liquids on normal skin. METHODS: The skin changes, responding to repeat patch testing with 10 hand dishwashing liquids, were measured by visual scoring. RESULTS: The results are summarized as follows; 1. Of the 16 healthy volunteers 8 had reactions. 5 women and 3 men, but there was no significant difference in irritancy between men and women. 2. The mean irritancy scores of the 10 hand dishwashing liquids ranged from 0.06 to 0.88. 3. A prominent increase in the degree of erythema in the first 24 hour patch test did not persist beyond exposure day 5, but after day 5, augmented responses of the erythema and scales, even fissuring occurred. 4. The pH of the test solutions of the hand dishwashing liquids ranged from 5.0 to 6.0, but there appeared to be no correlation between pH and irritancy in the dishwashing liquids tested. CONCLUSION: Our data suggests that regular exposure to hand dishwashing liquids may cause disturbances of the skin in a substantial proportion of individuals, and workers should use hand dishwashing liquids in lower concentrations than recommended and only for short periods with protective measures.

Measurements of mitral flow velocity by pulsed Doppler echocardiography are very useful in evaluating left ventricular diastolic filling properties. In hypertensive patients, abnormalities of diastolic function may precede systolic abnormalities and may serve as a more sensitive marker of end organ damage. We estimated left ventricular nass by 2-D echo short axis area-length method and compared with peak mitral flow velocity in early diastole(PFVE)and during atrial systolic(PFVA). There was a significant increase of LV mass and LV mass indices in the hypertensive patients and PFVE/PFVA ratio was decreased in them. Aithough there was no relationship between blood pressure and PFVE/PFVA ratio, a significant relationship was demonstrated between LV mass index and PFVE/PFVA ratio in the hypertensive patients.

A retrospective study was designed to determine the diagnostic contribution of oblique view in 740 consecutive lumbar spine examinations done in adults. In 12 cases (1.62%) there was a change in the radiographic interpretation when the oblique views were used for diagnosis. Considering the significant gonadal radiation, additional cost, and limited diagnostic value, the authors feel that the oblique view should not be a routine part of the initial lumbar spine examination in adults.
