The nodular vasculitis described by Montgomery on 1945 and is characterized by relatively chronic, persistent, or recurrent nodular lesions of nontuberculous origin chiefly on the legs. In the differential diagnosis the following must also be considered; erythema induratum, eythema nodosum, Weber-Christian disease, erythema nodosum migrans, recurrent thrombophrebitis and periarteritis nodosa. The authors observed one case of nodular vasculitis caused by sulfa drug. This patient was diagnosed to papulonecrotic tuberculid at first and treated by prednisolone 20 mg, INH 300 mg and streptomycin l.0 gm BIW. By the treatment, the patient, was cured completly within 3 months but visited again because of recurrence after 6 months. Therefore, same medication was given, but did not show improvment and added sulfa drug, Lederkyne. But, unfortunately the skin lesions was aggrevated after sulfa medication. It was suggestive that the cause of aggrevation was sulfa drug and discontinued the sulfa drug. The skin lesions were completely cured after the drug was discontinued.

The authers observed one case of typical poikilodermatomyositis who was 47 year old female. The poikiIodermatomyositis is a rare disease which is a variant of dermatomyositis and has never been reported in Korea. This patient complained of a weakness of left lower leg and tingling sensation of both fingers since one year ago, And she has a difficulty of both finger flexion since 20 days ago. The skin lesions revealed mottled dark brownish pigmentation, hardness, scattered atrophic patches and telangiectasia in the lesion on the left lower leg since one year ago. The same skin changes appeared on the thigh, lower abdomen and upper chest on 4 months ago. Histopathologically, a biopsy was performed from the skin of lower leg, the skin shows typical poikiloderma, i.e. the epidermis shows moderate atrophy of the stratum malpighii, flattened rete ridges and hydropic degeneration of the hasal cells. The dermis is edematous and a band like dense lymphocytic cellular infiltration. And the muscIe biopsy from gastrocnemius muscle shows dermatomyositis finding which the muscle bundles are edematous and degenerative. Many inflammatory cells present between muscle bundles but there is no suppurative change. Diagnosis was confirmed by clinical appearance, histopathologically and other laboratory studies. The patient was markedly improved by the prednisolone 80 mg and vasculat (vascular dilatator) 100 mg daily.

Trichoepithelioma, a tumor of the hair follicle, is usually seen as multiple lesions, but occasionally appears as a single tumor. Multiple trichoepithelioma is a dominant hereditary skin conditions whereas solitary trichoepithelioma is not hereditary and is growing tumor, usually seen in adults. A case of 56 year old housewife with solitary trichoepithelioma was reported. The skin lesion appeased as a firm, skin colored papule and the size was 0.5cm in diameter on right side of nose. Shaving biopsy was done and showed a high degree of differentiation toward hair structure and horn cyst that the keratinization is abrupt and complete. The methood of treatment is a surgical excision and electrodesiccation but remain a scar due to surgical trauma. And so, we used a 5-fluorouracil ointment instead of surgical excision and electrodesiccation, The skin lesion on nose was cured completely as a result of 5-FU ointment application without any scar formation cosmetically.

We studied 193 Diabetics without any symptoms of coronary artery disease and 39 Normal healthy subjects as Control group, using treadmill exercise test and obtained following results. 1) The positive rate was significantly higher in Diabetics(19.4% in Normal ECG groups and 25.4% in total Diabetics)than Control groups(5.1%)(0.01
0.05). 5) There was no difference in HbAIC, Total cholesterol and Triglyceride between positive and negative groups(P>0.05). In summary, with exercise test, the positive rate was higher in Diabetics than in Normal control groups and it seemed to be treadmill exercise test is a useful screening method for evaluation of coronary artery disease as well as for assesment of treatment and follow up care.

Reiters syndrome is an unusual disease characterized a triad of nongonococcal urethritis, conjunctivitis, and arthritis in association with the mircoutaneous lesions of keratoderma blenorrhagica and balarintis circinata. We present herein a case of Reiters syndome combined yiti lung cancer. A 39-year-old man has experienced naigrating polyarthralgia and high fever ilitermittently for about 20 years, Hyperkeratotic erythemnous patches and plaques, which dyeliped about 1 year ago, have aggravated and expanded to the whole body. Histopathologic sections from the plaque on the right forc ari showed characteristic findings including thickened parakeratotic horny layer and spongiform micropustules of Kogoji He was associated with HLA-B27. On the chest X-ray, a thumbtip size mass was incidently found. Chest CT and bone scan findings supported lung cancer and multiele metastases.

BACKGROUND: Puromycin aminonucleoside (PAN) is a known podocytotoxin. PAN-induced nephrosis is a widely used animal model for studying human idiopathic nephrotic syndrome. Abnormal protein accumulation associated with podocyte-specific endoplasmic reticulum (ER) stress damages cells structurally and functionally, which in turn induces apoptosis and severe proteinuria. In the present study, we investigated the effect of PAN on ER stress and apoptosis in podocytes in vitro. METHODS: Mouse podocytes were cultured and treated with various concentrations of PAN. ER stress markers were then evaluated by western blotting, and apoptosis was evaluated by fluorescence-activated cell sorting (FACS) and terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assays. RESULTS: PAN treatment increased ER stress markers such as activating transcription factor (ATF) 6α and caspase-12 in a dose-dependent manner at 12 and 24 hours, respectively. These markers were reduced by chemical chaperones, such as sodium 4-phenylbutyric acid and tauroursodeoxycholic acid. PAN treatment also increased 78 kD glucose-regulated protein (GRP78)/binding immunoglobulin protein (BiP) at the earlier stage of 12 hours. PAN significantly induced podocyte apoptosis in concentration- and time-dependent manners, as seen using FACS and TUNEL assays. This result was improved by Nox4 siRNA, ATF6 siRNA, and chemical chaperones. LY294002, a PI3-kinase inhibitor, significantly boosted ER stress and apoptosis. PAN-induced ER stress increased oxidative stress and subsequently induced apoptosis, and could be mitigated by inhibition of PI3-kinase signaling. CONCLUSION: Our findings suggest that PAN induces ER stress in podocytes mainly through the GRP78/BiP, ATF6α, and caspase-12 pathways, which trigger apoptosis via induction of oxidative stress. This stress is mitigated by inhibiting PI3-kinase signaling.

The author investigated the allergic contact dermatitis patients which visited our out-patient skin dispensary during 1969 and 1970. The patients were evaluated arcording to age, sex and cause of the disease. Furthermore, the patients were analysed as to the causative allergic contact factors by clinical inspection and history. The causes were confirmed by the patch test which was done on 88 of the allergic contact dermatitis patients. It is believed that patch test is clinically a most reliable procedure for the determination of responsible antigenic substance in allergic contact dermatitis and the positive reactions may be labelled as latent or potential hypersensitivity(Hjorth et al, 1968; Maibach, 1965). There is a group of chemicals used on the so-called routine screening patch test tray, which have proved to be frcquent causes of allergic contact dermatitis. Many diagnostic groups of chemicals and therapeutic trays, shoe trays, metal trays, etc., in addition to the standard routine screening patch test tray are used. Certain allergens seem to cause dermatitis in all countries hut many sensitizers vary from one country to anothcr (Calnan, 1955), The author has tried to establish a standard routine screening patch test tray fitted to our country according to the basic consideration used with standard routine patch test trays of the Skin and Cancer Unit, New York University Hospital. Paraphenylene diamine, ammoniated mercury, mercury bichloride, formalin, crude coal tar, potassium dichromate and mercaptobenzothiazole were the most potent sensitizers. These chemicals must be included in our standard screening routine patch test tray. However, the patch test results and the present clinical dermatitis (i.e. cosmetic dermatitis and rubber or leather dermatitis) did not coincide. Further investigation for the establishment of a proper stanard patch test tray for Korea should be carried out.

We report a 36-year-old male with the bilateral visual field defect following LASIK was observed. Preoperatively, patient had high myopia(right. -7.25 0.75x18, left. -7.5-0.5x12), normal intraocular pressure(IOP)(right/left: 16/14 mmHg), normal visual field(Humphrey 30-2 visual field)and revealed the tilted discs with symetric optic nerve head cupping(cup-to-disc ratio, 0.70), parapapillary atrophy. Bilateral LASIK keratorefractive surgery was on the same day and intraoperative complication was not noted. After the first operative visit day, examination revealed uncorreted visual acuity right 0.8 and left 0.6 but scotoma was reported. Three months later, Humphrey 30-2 visual field revealed a near-superior altitudinal defect in the right eye and nasal side visual field defect in the left eye. Best corrected visual acuity was 1.0 in the right eye, 0.8 in the left eye. Repeated visual fields over a 11-month period postoperatively showed stability of the defect, with IOP of 12 mmHg to 15 mmHg in each eye. We considered LASIK uses a microkeratome vaccum ring to make a corneal flap, transient elevation of IOP alters the microcirculation of optic nerve head and may have precipitated visual field defect.
