It is important to maintain normal calcium concentration especially ionized calcium concentration in chronic renal failure patients on hemodialysis. The direct measurement of ionized calcium is less commonly used due to a lack of automated equipment as well as the cost of laboratory equipment. Numerous formulas for adjusted total calcium and calculated ionized calcium are used in clinical practice. We examined the relationship between direct measured ionized calcium and total calcium, corrected total calcium, calculated ionized calcium (formula of Nordin et al) in 53 chronic renal failure patients on hemodialysis. The results were as follows; 1) In predialysis group, plasma total and ionized calcium levels were 2.36+/-0.26, 1.04+/-0.21mmol/L respectively, and higher than normal controls. The correlations between plasma ionized calcium and total calcium, calculated ionized calcium, corrected total calcium were r=0.72 (P=0.0001), r=0.81 (P=0.0001), r=0.65 (P=0.0001) respectively. The plasma ionized calcium level was not correlated with the level of albumin, pH, phosphate, parathyroid hormone. 2) The plasma total and ionized calcium levels were significantly increased with hemodialysis and values were 2.49+/-0.14mmol, 1.14+/-0.14mmol/L respectively. The correlation between ionized and total calcium was r=0.41 (P=0.0021). These results suggested that the calculated ionized calcium (formula of Nordin et al) and total calcium can be used to predict the plasma ionized calcium level in chronic renal patients on hemodialysis.

This study was conducted to observe immunological abnormalities, vscular changes and abnormal maturation, pathway of keratinocyte in the psoriasis, by comparing drposits of IgG, fibrinogen(FG) and fibronectin(FN) in the invnlved and uninvolved skin of 19 psoriaics before treatment, the involved skin of 12 among the above patients after treatment, and the skin of 8 normal controls. The study was carried out by using direct immunofluorescence technique with anti-IpG, anti-FG, anti-FN antibodies. The results are summarized as follows: 1. In the uninvolved skin of 19 psoriatics before treatment, no depasition of IgG was observed while deposition of FG was present at the dermo-epidermal junction in 5.3% of the patients and dermis(10.5 %). Deposition of FN was found at the dermo-epidermal junction(52%), papillary dermis(57.9%) and dermal blood vessels(52.6%). 2. In the involved skin of 19 psoriatics before treatment, deposition of IgG was observed in the horny layer in 84.2% of the patients, upper epidermis(15.8%) and depositicin of FG was present in the horny layer(52.6%), upper epidermi(63.1%), dermo-epidermal junction(15.8%), upper dermis(15.8%) and dermal blood vessels(5.3%). Leposition of FN was found in the horny ayer(26.3%), upper epidermis (36.8%), dermo-epidermal junction(78.9%), upper dermis(89.5%) and ermal blood vessels(68.4%). 3. In the involved skin of 12 psoriatics after treatment, IgG was wealily deposited in the horny layer in 16.7% of the patients and deposition of FG was observed in the horny layer(8.3%), upper epidermis (16.7%), dermo-epidermal junction(8.3%) and dermis(8.3%). Deposition of FN was found in the upper epiderrnis(8.3%), dermo-epiderrnal junction(58.3%), dermis(66.%) and dermal blood vessels (33.3%) 4. In the normal skin of 8 control subjects, no deposition of IgG and, FG was observed while deposition of FN was found at the inummo-epidermal junction in 37.5% of the persons, upper dermis(25%) and dermal blood vessels(12.5%)

A 23-year-old male patient had 65 nodules of 0.2~0.7 cm in diameter nn scrotum. Elliptical excision was done to remove the nodules situated on the middle part of the scrotum. For small multiple nodules on the lower part of the scroelectrocogulation and curretage was performed. Excellent results were obtained by two modalities of treatment.

We experienced a cose of occupational asthma induced by the tobacco leaf in 49-year old man. He has worked at the Korean Tobacco and Ginseng company for 23 years but suffered from the intermittent mild wheezing and dyspnea since 6 years ago. He has not involved in the process making the tobacco directly, but just managed it at the storage barn. He showed a whole negative reaction to 55 inhalant allergens(Bencard, UK) and the allergen extracted from the yellow Korean tobacco leaf, but showed the dual asthmatic respose to the allergen bronchial provocation test with it. His basal PC is 6.35 mg/ml with methacholine inhalation challenge. Now he changed the workplace far away from the barn at the same company and is treated with bronchodilator and anti-asthmatic inhaler.

Injectable Collagen Implan, is composed of purified bovine dermal collagen emulsified in saline and lidocaine(0.3%) base, and has been promoted for correction of soft tissue contour defects. Although collagen is a relatively nontoxic, nonimmunologic and biolegically nonreactive biomaterial, some side reactions have been reported. We report herein a case of cutaneous side reaction to collagen implantation in a 38-year-old female. The patient presented with puritic, irritating, multiple, erythematous nodules on both the temporal and interorbital area, which had been observed since 1 day after collagen(KOKEN ATELOCOLLA-GEN IMPLANT-Japan) implantation. Histopathologic findings showed dense infiltration of acute and chronic inflammatory cells in the dermis, especially the perivascular and periadnexal area.

A 34-year-old woman presented with several intensely pruritic erythematous serpiginous thread-like skin lesions which began as a small papule on the epigastrium 4 months prior to her visit and was migrating to the left chest area. The laboratory examination showed eosinophilia and the total serum IgE level was slightly increased. Histopathologic examination revealed a pustular burrow in the epidermis with a larva-like cystic lesion apart from the burrow in the epidermis. The patient was treated with topical 10 % albendazole cream 3 times daily for 1 week without recurrence for 22 months up to now. We thought this was a rare case which was confirmed by a skin biopsy showing larva in the epidermis.

Clinical history and dermatological examinations were performed in 51 patients with contact dermatitis due to metal working fluid who were working at the metal industry. Patch tests were also performed with standard series and oil cooling fluid series. Chronic lichenified eczema such as lichenified and fissured was the most common clinical type(45.1%). 19 patients had positive reaction to either one or more of the standard series and oil & cooling fluid series. We found ammoniated mercury chloride was the most common sensitizer in standard series, followed by potassium dichromate, 4-phenylendiamine dihydrochloride, cobalt chloride, nickel sulfate, quinoline mix and cabra mix. Microbiocide was the most common allergen(4 of 6 positive result in oil & cooling fluid series.

Cutis naarmorata telangiectatica congenita(CMTC) was first lesribed by Van Lohuizen in 1992. Cases of CMTC were reported later under various names, includir gan Lohuizens syndrome, congenital generalized phlebectasia. congential phlebectasia and reticulatever scular nevus. It is charaterized by persistent livedo reticularis, telangiectasia and phlectnsia from birch hand atrophy and superficial ulceration of the overlying skin are uncornmonly encountered. They have a steady improvement with time, however various congenital abnormalties, such as varicosities, hen ariomas, hypoplasia or hypertrophy of soft tissue and bones, rarely generalized congenital fibrornatos ectal and genital anomaliies may be associated in approxirnately 50 percent of patients. In case 1, the patient was 45-day-old female infant with reticulated mottling and atrophy of the skin on the right leg. In case 2, the patient was 30-day-old male infant who depressed, bluish, and reticulated patches on the both upprarms, right side trunk, buttock and loen leg. Decreased circumferences of the affected extremities vas observed in case 2. No other assotated anomalies were found in physical and X-ray examinatiorwlin both cases. The skin biiopsy of bothed similar findings, which revealed mild dilatation and proliferation of capillaries, mild inflammatoryel infiltration and extravasated red blood cells in the dermis. The clinical follow-up, alneast all of th lisions disappeared spont.anously in 1 year at case 1, and some of lesions also disappeared in 3 month, 11 case 2. In addition, we reviewed and summerized the reported cases in Korea.
