PURPOSE: This study evaluated the differences of intraocular pressure (IOP), corneal thickness, and corneal endothelial morphology compared with age-matched, healthy control subjects, as well as the correlation according to the duration of diabetes. METHODS: Goldmann applanation tonometry, ultrasound pachymetry, and non-contact specular microscopy were performed in 200 patients with diabetes and 100 control subjects. RESULTS: The diabetic subjects had higher IOP, thicker cornea and less cell density, less hexagonality, and more irregular cell size of corneal endothelium than the controls (P<0.05). Central corneal thickness and coefficient of variation in cell size were higher in diabetes of over 10 years duration than in diabetes of under 10 years duration (P<0.05), while endothelial cell density and percentage of hexagonal cells were lower in the diabetes of over 10 years group (P<0.05). Central corneal thickness was correlated with duration of diabetes but IOP and corneal endothelial morphologic characteristics were not. CONCLUSIONS: Especially, those with a diabetes duration of over 10 years have more corneal morphological abnormalities and a higher IOP than normal subjects. Therefore, any surgical procedures should be performed carefully in the diabetic cornea that is easily damaged by, for example, phacoemulsification.

BACKGROUND: Electronic bulletin board systems have been used for education, information exchange, and medical consultation for a number of years. However, most of these systems have been text-based. The field of dermatology has never had a system that allowed a quick exchange of visual information. OBJECTIVE: Dermatology is a field of medicine which especially requires a visual image for an accurate diagnosis, and subsequent effective treatment. We have developed a web-based bulletin board system which can be used by any clinician with access to the internet to view clinical images of skin diseases with accompanying clinical findings. METHODS: A web-based bulletin board system was developed for the internet. The system is designed to operate independently of client hardware and software using hyper text markup language so participants using different platforms can access and use the site effectively. RESULTS: Any participant can easily upload a diagnostic image to the board along with relevant clinical information. Other participants can make comments regarding the presented case which may prove useful to the presenter in diagnosis and development of an effective treatment modality. CONCLUSION: Our web-based bulletin board system for discussion of skin diseases has the potential to help in the diagnosis and treatment of various skin diseases. Dissemination of information relating to clinical cases and participation of a widespread audience of experienced clinicians will allow better practice of dermatology and aid in further training of inexperienced clinicians.

Churg-Strauss syndrome(CSS) or allergic angiitis and granulomatosis is a disorder characterized by pulmonary and systemic small-vessel vasculitis, extravascular granulomas, and hypereosinophilia. It occurs in individuals with asthma and allergic rhinitis. The diagnosis of CSS is made on the basis of clinical and pathologic features. According to 1990 American College of Rheumatology(ACR) criteria for the classification of CSS, 6 criteria were developed. The presence of 4 or more of these criteria yielded a sensitivity of 85% and a specificity of 99. 7%. We describe a case of CSS in a 62-year-old female who met all of 1990 ACR criteria, but presented as like a as rheumatoid arthritis initially. Clinical symptoms, laboratory and roentgenographic findings gradually responded to high dose prednisolone treatment and resolved 3 weeks later. After discharge, she has been treated with oral prednisolone in a tapering course. Although polyarthritis with eosinophilia, vasculitis, and neuropathy are clinical manifestations of rheumatoid arthritis, those maniestations frequently occur during the vasculitic phase of the CSS. This case suggests that thorough differentiation of extra-articular manifestations of RA from clinical manifestations of CSS is considered when we meet a patient who have polyarthritis and vasculitis.

OBJECTIVE: To determine the effects of leukemia inhibitory factor (LIF) on embryonal development in in vitro culture. METHODS: This is designed in vitro model using eggs from mouse. The eggs from mouse were assigned 29 for control group, 53 for 20 ng/ml of LIF, 88 for 40 ng/ml of LIF, 68 for 80 ng/ml of LIF respectively for in vitro fertilization. And 26 fertilized eggs at 2 cell stage from mouse also were assigned. The mouse embryos of all groups were cultured in medium supplemented with LIF in different concentrations, whereas the eggs in control group was cultured in medium without supplement of LIF. RESULTS: At 72 hours culture of eggs from in vitro fertilization, there was a slight increas in rate of embryonal development to morula in both LIF-20 and LIF-40 as results of 64.15% and 75% respectively, while 42.65% in inferior rate of LIF-80, compare with 51.72% in control group. But the difference between these each groups were not significant in statistically (p< or =0.05). And after 96 hours culture of eggs, the rates blastocyst formation was significantly higher in both LIF-20 and LIF-40 as 56.6% and 63.63% than those in control and LIF-80 as 44.83% and 35.29% respectively. On culturing eggs from in vivo fertilization, the rates of blastocyst formation was significantly not only higher as 85% and 81.81% respectively in medium supplemented with LIF-40 and LIF-80 than 42.3% in LIF-20 but also embryonal cell viability were remakedly improved at 96 hours after culture. CONCLUSION: The LIF in low dose is embryotrophic, but LIF in high dose is embryotoxic on eggs from in vitro fertilization. Whereas on culturing eggs from in vivo fertilization, LIF is more beneficial with dose dependent in high concentration.

Phakomatosis pigmentovascularis(PPV) was first described in 1947 as a distinctive association of vascular and pigmentary nevi by Ota et al. Hasegawa et al subclassified the disorder into eight types and type I a is characterized by the coexistence of nevus flammeus and nevus pigmentosus et verrucous, which is not associated with systemic organ involvement. PPV type I a is relatively rare and a case with multiple pyogenic granulomas developed in pregnancy, is not reported yet. We present a case of PPV type I a with multiple pyogenic granulomas developed in pregnancy within nevus flammeus in a 29-year-old female.

Lightning injury is uncommon, as evidenced by the fact that most physicians never see or treat such a victim. To our knowledge, there were no reports of lightning burn with flame burn. We report a case of lightning burn with flame burn. On a rainy day, a 64-year-old woman with an umbrella in her left hand was walking along a road. When lightning struck the tip of her umbrella, her clothes were flamed. She threw herself into the water in a nearby field. The fire was extinguished. Then she lost consciousness, but she regained consciousness immediately. She was transported to our hospital. On arrival at our emergency center, her physical examination was remarkable. The patient had an entrance wound of the left palm and an exit wound of the left foot as well as 25 % total body surface burns, which were present in the flexor surface of the left hand, left arm, left leg and left flank. Histopathology showed epidermal and dermal necrosis. Three months later the burns were healed spontaneously, with some remaining scars.

Isolated true atherosclerotic aneurysm of the distal superficial femoral artery is rare disease. We experienced a case of distal superficial femoral artery aneurysm not associated with dilatation of the common femoral or popliteal artery. True arterial aneurysms are attributed to the weakening of the arterial wall due to atherosclerosis. True superficial femoral artery aneurysms were predominantly founded in elderly men and used to be diagnosed by ultrasonography, CT or angiogram. We report a case of distal superficial femoral arterial aneurysmal rupture in elderly woman who has a rheumatoid athritis and diagnosed by ultrasonography. We performed aneurysmal excision and interposition graft with PTFE.

BACKGROUND: It is well known that the prevalence of lung cancer is higher in idiopathic pulmonary fibrosis(IPF) patients than in the general population. This high prevalence is explained by the concept of 'scar carcinoma'. There have been several reports on the prevalence of histologic type of lung cancer in IPF with conflicting results. Despite of the high smoker rate in almost all previous reports, none considered the smoking history of patients. Therefore we performed a separate studies on fibrosis associated lung cancer and smoking associated lung cancer. The purpose of this study is to investigate the proportion of lung cancer in IPF that is fibrosis assiciated and to determine the most common histologic type in fibrosis associated lung cancer in IPF. METHODS: A retrospective review of medical records and radilolgic studies was performed for cases of lung cancer with IPF. We investigated smoking history, sequence of diagnosis of lung cancer and IPF, histologic type of lung cancer and the cancer location, especially whether the location is associated with fibrosis. To evaluate the proportion of fibrous associated lung cancer, the lung cancer in IPF were categorized according to the presence of fibrosis at cancer location. RESULTS: Fifty seven patients were subjects for this analysis. Six(11%) cases were diagnosed as lung cancer during follow-up for IPF, and both diseases were diagnosed simultaneously in the others. Ninety four percent of patients were smokers and the average smoking amount was 47.1±21.9 pack-year. Among the patients with IPF and lung cancer, 42(80.8%) cases were considered as 'fibrosis associated'. The remainder was 'not fibrosis associated' and probably was due to smoking etc. Although the most frequent histologic type was squamous cell carcinoma as a whole, adenocarcinoma was the prominent histologic type in 'fibrosis associated lung cancer.' CONCLUSION: Considering the proportion of 'fibrosis not associated lung cancer' in the patients with IPF and lung cancer, significant proportion of lung cancer in IPF may not be fibrosis induced. This may influence the distribution of histologic type of lung cancer in IPF.
