2.A study of spinal mineral assessment using quantitative computed tomography
Journal of the Korean Radiological Society 1986;22(5):836-847
For determination of reliability and clinical applicability of spinal mineral content assessed by quantitativeCT, the basic experiment was undertaken to assure the correlation of CT numbers of calibration material withinphantom and human vertebral specimen. And the analytical study of mineral contents assessed by whole body CT in 208 normal persons was performed at Pusan Natinal University Hospital for these last two years. The resultsobtained were summarized as follows: 1. The concentration of solution of dipotassium hydrogen phosphate had a highcorrelation with CT number with correlatin coefficient of 0.99. 2. in experimental study, the method fordetermining the mid-vertebral line in lateral scout view showed the precision of 1.4%(coefficient of variation).3. Short term precision test for mineral content of spine specimens showed 1.9%(coefficient of variation) and longterm precision test showed 2.4%(coefficient of variation). 4. Mean mineral content of lumber spines in normal malewas 139.0±35.70mg K2,HPO4/cm3, and the highest value was 167.3±22.96mg K2 HPO4/cm3 in the age range of 20–29years. With increasing age, there was a gradual loss of mineral. so that by age 70 the mineral content was reducedto 85.2±19.95mg K2 HPO4/cm3. 5. Mean minearal content of lumbar spines in normal female was 128.7±41.87mg k2HPO4/cm3. the highest value was 169.5±20.46mg/ K2 HPO4.cm3 in second decade. There was gradual decrease inmineral content to 62.2±25.45mg K2 HPO4/cm3 by 70 years of age. 6. From 40's of age the average mineal content ofspine was decreased by 70's, the mineral content in normal women was reduced by 62%, and that in normal men by 47%. 7. After 40's in women, the mineral content of spine was markedly reduced, and the level of mineral contentin women was lower than in men.

Annals of Dermatology 2003;15(1):27-30
Cutaneous polyarteritis nodosa(CPAN) is a benign form of rare vasculitis of small and medium-size arteries with a recurrent but benign course without systemic involvement. We experienced a 61-year-old male who had two months history of multiple deep-purpurish livedo reticularis on both lower legs. Noncutaneous manifestations including malaise, fever, myalgia, and arthritis were absent. A skin biopsy specimen from the livedo reticularis on the leg showed perivascular and trans-mural neutrophilic and lymphocytic infiltration of medium-sized arteries in the dermal-subcutaneous junction and fibrinoid necrosis of the vessel walls. The patient was treated with colchicine for 2months and showed markded improvement.

BACKGROUND: The clinical and histopathological classification of erythema multiforme(EM) and Stevens-Johnson syndrome (SJS) are difficult due to a lack of clear-cut criteria. In recent studies, some authors suggested that erythema multiforme and Stevens-Johnson syndrome were clinically and histopathologically different disorders. OBJECTIVE: The purpose of this study was to review the clinicopathological characteristics of the EM and SJS and to suggest specific findings for differentiating between the two diseases. METHODS: Fifty four patients with EM and SJS diagnosed in the Department of Dermatology of Dong-San Hcepita1 from January 1987 through to December 1996 were studied retrospectively. RESULTS: The results were summarized as follows. l. In view of causal factors, 54 cases were classified as drug-induced (n=22, 41%), herpes-induced (n=16, 30%), tuberculosis (n= 2, 3%), pneumonia (n=l, 2%), unknown (n=13, 24%). 2. Fifty four cases were clinically classified as SJS (n= 29, 54%), EM minor (n=-15, 2S%) and EM major (n = 10, 18%). 3. Erythema multiforme was found to be more related to herpes (13 of 25 cases) than to drugs (3 of 25 cases), while SJS was more related to drugs (19 of 29 cases) than to herpes (3 of 29 cases). 4. Varying degrees of necroti changes of keratinocytes were found in all the cases. The severity of degree or extent of necrosis was higher in patients with SJS than EM. 5. In demial changes, EM showed differences from SJS by having a denser and deeper lymphocytic infiltrate, and increased amount of extravasated erythrocytes. CONCLUSION: Taken together, although our findings could not provide a defmite clue to determine whether EM and SJS are different distinet entities or not, this study may be useful to differentiate and to understand the pathogenesis of EM and SJS. A prospective large scaled study should be conducted to definitively characterize these entities.

We herein report a case of therapy-resistant dermatomyositis treated with oral prednisolone and chlorambucil combination therapy. Concurrently, she showed cervical carcinoma in situ(CIS). Initially, we started to treat her with combination oral prednisolone, intramuscular methotrexate, hydroxychloroquin, and removal of cervical CIS. However, our patient failed to respond to these regimens. Thus, we had have another combination treatment of oral prednisolone and chlorambucil. After the treatment of this combination regimen, her recalcitrant dermatomyositis improved dramatically without recurrence. There were no significant adverse side effects with chlorambucil therapy.

Agnogenic myeloid metaplasia (AMM) is a myeloproliferative disorder characterized by leukoerythroblastosis, tear-drop erythrocytes, extramedullary hematopoiesis with hepatosplenomegaly, and varying degrees of myelofibrosis. The mean age at presentation is about 60 years, and pediatric cases are rare. We experienced a case of AMM in a 9 months old female who was presented with pallor, huge splenomegaly and intermittent fever. Peripheral blood showed leukoerythroblastosis poikilocytosis, and tear drop cells. Bone marrow was difficult to aspirate, and biopsy specimen showed increased reticulin with decreased cellularity, which was compatible with myelofibrosis. We presented a case of AMM with brief review of the literatures.

Unilateral absence of the articular process at a lumbar vertebra is a rare anomaly. The etiology of the congenital absence of articular process is not precisely determined yet, but it was explained as some of the possible embryologic bases. Absence of the articular process at the level of L5-Sl have been reported a few, but anomaly above L4 is rare. We are reporting a case of absence of articular process at the level of the 4th lumbar vertebra.

Kaposi's sarcoma is a rare tumor comprising 0.1 per cent of all malignancies worldwide. There is, however, an increased ineidence following renal transplantation, immunosupression and in the acquried immunodeficency syndrome(AIDS) Kaposi's sarcoma has been shown to involve every organ of the body except the brain. Gastrointesinal involvement is the most common extracutaneous site of involvement. Gaatrointesinal Kaposis sarcoma is preaent in approximately half of patients with cutaneous Kaposis sarcoma and the acquired immune deficiency syndrome(AIDS). Although usually asymptomatic, gastrointestinal Kaposi's sarcoma may cause pain, bleeding, diarrhea, obstruction, intussusception, perforation. malabsorption, and protein-losing enteropathy. Three distinct gastroscopic appearances of Kaposi's sarcoma have been described: maculopapular, polypoid, and umbilicated nodular lesions. We report a case of Kaposis sarcoma of the stomach.

The potential of malignant melanoma to metastasize to all parts of the body is well known. Metastatic melanoma of the stomach may present with vague gastrointestinal symptoms, abdominai pain, or gastrointestinal bleeding. When gastrointestinal symptoms occur in a patient with known melanoma, gastric metastases should be considered. Melanoma metastatic to the stomach develops multiple small ulcerating masses. These sharply delineated submucosal lesions have been described as having a "bull's eye" or "target" configuration. Barium X-ray study, endoscopy, cytology study, and biopsy may yield the diagnosis. The prognosis is poor. We report a case of metastatic melanoma of the stomach with the review of the literature.
