PURPOSE:We performed this study to compare correlation between the indices of insulin resistance using fasting insulin and glucose level and body mass index (BMI), and to determine the clinical usefulness of glucose/insulin ratio (G/I ratio), which is easily available in clinical base. METHODS:Total 119 children with simple obesity, whose BMI is over 95th percentile, were evaluated. We calculated G/I ratio, logInsulin, HOMA-IR, logHOMA-IR, and QUICKI and evaluated their relationship to BMI. RESULTS:Children with high-degree obesity had higher insulin resistance than children with mild to moderate-degree obesity (logInsulin, 1.13+/-.23 vs 1.27+/-.29; logHOMA-IR, 0.46+/-.24 vs 0.61+/-.30; QUICKI, 0.33+/-.03, 0.31+/-.03)(P<0.01), and pubertal children had higher insulin resistance than prepubertal children (G/I ratio, 7.39+/-.07 vs 4.85+/-.29; logInsulin, 1.14+/-.27 vs 1.31+/-.22; logHOMA-IR, 0.47+/-.28 vs 0.65+/-.22; QUICKI, 0.33+/-.03 vs 0.31+/-.02) (P<0.001). BMI had correlation coefficient as -0.436 for QUICKI, -0.432 for G/I ratio, 0.430 for logInsulin, and 0.425 for logHOMA-IR (P=0.000). G/I ratio was well correlated with QUICKI (r=0.901, P=0.000), logHOMA-IR (r=-0.865, P=0.000), and logInsulin (r=0.899, P=0.000). The changes of BMI were correlated with changes of G/I ratio (r=-0.547, P<0.01), QUICKI (r=-0.464, P=0.01), and logHOMA-IR (r=0.429, P<0.05). CONCLUSION: This study revealed that the degree of BMI had statistically significant correlation with insulin resistance, which can be reflected by G/I ratio, logHOMA-IR and QUICKI. G/I ratio was well correlated with logHOMA-IR and QUICKI, which suggests that G/I ratio could be used as an bedside index of insulin resistance. The changes of G/I ratio were more correlated with changes of BMI than those of logHOMA-IR and QUICKI.

BACKGROUND: Intra-aortic balloon pump (IABP)is well known for its hemodynamic benefit but still has its own complications.Proper use of IABP is the best way t o obt ai n maximum benefit with low complication rate. MATERIALS AND METHOD: Twenty one(men 10,female 11) patients were included in this study among the 100 consecutive adult cardiac surgery patients in our hospital.Eighteen(85.7%)were ischemic heart disease patients.They all received IABP therapy due to postcardiotomy cardiogenic shock according to the well-known indications.Their preoperative conditions,intraoperative factors including hemodynamics, postoperative conditions and IABP-related complications were analyzed. RESULT: Nineteen patients(90.5%)were successfully weaned from IABP.There were 2 patients of operative death and the mortality rate was 9.5%.Duration of IABP use was 40.7+/-24.3 hours.There were 2 cases(9.5%)of IABP-related vascular complications that required surgical intervention. CONCLUSION: We concluded that IABP could be used effectively and safely for postcardiotomy cardiogenic shock patients with low complication rate.

A case of multiple trichilemmal cysts (TC) is presented. TC is known to be a kind of keratinous cyst with lining cells showing trichilemmal keratiniration. A 63-year-old female patient presented with a 30 year duration of increasing in size and number of twenty five nodular lesions on the scalp. All twenty five TC on the scalp were totally excised and examined microscopically. However, the evidence of proliferation or malignant change like the previous case reports was not found in our case.

Six cases of lunate dislocation were treated in the departments of orthopaedic surgery, Hangang Sacred Heart Hospital and Kangnam Sacred Heart Hospital, Hallym College during the period from March 1, 1978 to August 31, 1982. The results were as follows; l. Among the total 6 cases, two cases had lunate dislocation only and the other four had associated injuries of the same wrist joints. 2. Marupulative reduction was successful in only one case. Five cases were treated by open reduction, and for four of them internal fixation was tried. 3. Postoperative roentgenograms showed acceptable reductions in all cases except one which redislocation occurred. This case showed lunate dorsiflexion instability and was treated with extensor carpi radialis longus tenodesis. 4. The cases with pure lunate dislocation yielded better functional recovery than those with associated carpal injuries.

A 55-year-old Korean female patient who presented with longitudinal black pigmentation affecting the right thumbnail is described. Direct microscopic examination of nail tissue in 15% potassium hydroxide and cultures on Sabourauds glucose agar revealed Candida species. Cardida species as a cause of longitudinal melanonychia has, to our knowledge, been described only once in the literature. Our case may be the second one.

Plexiform neurofibroma is considered a pathognomic of Von Recklinghousen's disease, which involves the deep and large nerve trunk. These are large irregular nerve fascicles which result from an increase in endoneural matrix within individual nerve facicles, without an increased number of nerve fibers. We experenced a case of Von Recklinghausen's disease in a 24 year-old male who had variable cutaneous skeletal, and CNS lesions. He presented multiple neurofibromas, cafe-au-lait spots, and axillary freckles as common cutaneous lesions of NF-I and giant pigmentation, sacral hypertrichosis, and plexiform neurofibroma as unusual cutaneous lesions. Also he had a scoliosis, bowing deformity of the humerous and wedging deformity of the body of the 5th cervical spine as a skeletal manifestation and cortical calcification in the occipital area as a CNS manifestation.

We present herein a case of pyoderma gangrenosum, which showed good response to cyclosporine therapy. The patient, a 47-year-old man, had suffered from a skin defect on the left anterior chest 2 months before the rapidly spreading pustules and ulcer with an inflammed, irregular undermined border appeared together with a hemorrhagic base which developed on his left anterior chest and upper abdomen. Cyclosporine was given orally in a dose of 150mg three times daily for 2 weeks, and tapering to 100mg three times daily for the next 3 weeks. Clinical improvement was observed after 14 day's treatment and all the skin lesions were replaced by granulation tissue with epithelialization after 35 day's treatment. After the 5-week period of treatment, blood urea nitrogen and creatinine rose to 29 and 1.8 mg/dl. Cyclosporine was stopped and then the patient was given prednisolone (10mg/day) in addition to dapsone(50mg/day) for 1 month. Recurrence has not been observed.

BACKGROUND: Although the histologic picture of epidermolytic hyperkeratosis is diagnostic for bullous congenital ichthyosiform erythrokerma (BCIE), it is not specific for it. It is found also in several other conditions, that is, linear epidermal nevus, epidermolytic keratisis palmaris et plantaris and epidermolytic acnthoma. Among these, BCIE is caused by mutations of the defferentiation s0pecific keratins K1 and K1-. These mutations produce a weakened cytoskeleton that is prone to collapse resulting I cell fragility and lysis. But the pathogenesis of epidermal nevus showing the similar histologic feature with BCIE is not known. OBJECTIVE: The purpose of our study is to conpare the electron microscopic picture and the immunohistochemical features, and to find the possible pathogenesis of both diseases. METHODS: We evaluated the clinical, histopathologic nd electron microscopic features of 5 BCIE cases and 14 epidermal nevus cases which were histologically diagnosed with epidermolytic hyperkeratosis at the department of dermatology at Wonju Christian Hospital, Shinchon Severance Hospital and Yongdong Severance Hospital, from January 1981 to June 1994. The immunohistochemical staining(PAP method) using monoclonal antibody against cytokeratin was performed on BCIE and epidermal nevus. RESULTS: Light microscopy of both BCIE and epidermal nevus showed the same histologic changes including hyperkeratosis, increased keratohyaline granules, acanthosis and perinuclear vacuolization of upper malpighia layer. Electron mioroscopic findings in both diseases were similar. Aggregation of tonofilaments is noted in the squamous cells, but is not evident in basal cells.In immunohistochemical study of both diseases, 34betaE12 is stained in the whole epidermis and is stuonger ex0ressed in the basal layer tan suprabasal layers. LP34 staining is evident in suprabasal cell layers up to the cornified cell layer. CONCLUSION: Electron microscopy and immunohistochemical study of both diseases showed the same finding. We thind that a defect in the differentiation specific keratins, K1 and K10 is perhaps involved in epidermal nevus histologically showing epidermolytic hyperkeratosis as in BCIE.

Chondroblastoma is a rare primary bone tumor which originates from cartilage, and represents approximate 1% af all bone tumor. The chondroblastoma arises most frequently from the epiphysis of the long bones with the humerus being the commonest site. It afflicts usually the young under 25 years with greater incidence in male. As there is no cartilage cell on craniofacial bone which is mainly fromed by intramembranous ossification, the chondroblastoma on the craniofacial bone is extremely rare. But the chondroblastoma recurred frequently in craniofacial bone when the mass is excised incompletely or curretted and, as the tumor has the outstanding ability of local invasiveness, it destructs the adjacent bone. In addition, it is difficult to diagnose differentially from sarcoma or giant cell tumor histopathologically. Due to the entities described above, it is necessary to remove the entire tumor mass as complete as possible, to treat with radiation pre or postoperatively for preventing from recurrence, and to observe for a long time. The chondroblastoma on temporal bone is rare and is difficult to diagnose and treat successfully. So we'd like to present a case of chondroblastoma which was originated from temporal side of TMJ with literatural review.
