We examined a male infant with transient increase in alkaline phosphatase(ALP) activity. The 25-month-old infant was admitted to a local hospital because of pneumonia of unknown etiology. Initial laboratory investigation revealed a serum ALP of 11,260U/L, which was comparable to that of bone isoenzyme on the electrophoresis pattern, There was no evidence of hepatitis, skeletal or intestinal diseases. The hyperphosphatasemia disappeared 3 months later. We report a case of transient hyperphosphatasemia diagnosed inci- dentally in the course of management of pneumonia.

PURPOSE: This study was undertaken to increase the knowledge of the intra- and extra-spinal alignments and to help recovery of sagittal alignment in operation by measuring the normal values of the spinal alignment in relation to hip axis as well as those of the thoracic, thoracolumbar junction, lumbar and lumbosacral junction of sagittal alignment and their correlation. MATERIALS AND METHODS: Whole spine standing lateral radiographs were taken in young 100 adults without spinal abnormalities clinically and radiographically. Intraspinal alignment was measured with angles of thoracic kyphosis, lumbar lordosis, maximum thoracic kyphosis, maximum lumbar lordosis, angle of the thoracolumbar junction, sacral inclination, segmental angles and disc angles respectively with special emphasis on lumbar lordosis. Extraspinal alignment was measured with sacropelvic angle, spinopelvic balance and spinal balance in relation to hip axis. Correlations among these parameters were analyzed. RESULTS: Lumbar lordosis and thoracic kyphosis were measured -49 degree(-22 - -79 degree) and 32 degree(6 degree-56 degree), respectively. Slight amount of kyphosis in thoracolumbar junctional area was considered normal. Lumbar lordosis had significant correlation with thoracic kyphosis and sacral inclination. However, there was no correlation between thoracic kyphosis and sacral inclination. Lowest two lumbar segments comprised 71% of total lordosis. Lumbar lordosis usually started at L1-2 and gradually increased at each level caudally to the sacrum. Sacropelvic angle, spinopevlic balance and spinal balance were measured -11 degree(-6 degree - 24 degree), -4 cm (-10 - 2 cm), and -2 cm (-7 - 4 cm) respectively with C7 positioned posterior to hip axis mostly. CONCLUSIONS: There was a wide range of normal sagittal alignment of the thoracic and lumbar spines, and normal values of these alignments were not easily defined. Therefore, normal patterns of sagittal curvature and sagittal balance should be more emphasized.

Endometrial papillary serous carcinoma (EPSC) is a distinct variant of endometrial adenocarcinoma that histologically resembles ovarian serous papillary adenocarcinoma and has an aggressive clinical course. Usually, the tumor is diagnosed at the advanced stage. The tumor has well confused with metastatic ovarian tumor of identical histology. Dignosis of EPSC should be considered when the cervico-vaginal smear reveals numerous papillary clusters of tumor cells with macronucleoli and psammoma bodies. Recently, we have experienced two cases of EPSC diagnosed on cervico-vaginal smears, which revealed characteristic cytologic features including numerous papillary clusters of tumor cells with macronucleoli. The cytologic diagnoses were confirmed on histologic sections.

Fibrous dysplasia is a common benign disorder of bone in which normal bone marrow is replaced with fibro-osseous tissue. As PET/CT is increasingly used for the staging of different malignant disease, incidentally found fibrous dysplasia with increased FDG uptake may mimic metastasis. We report on a 46-year-old woman with fibrous dysplasia who underwent PET/CT because of suspected recurrence of breast cancer and was misdiagnosed as a bony metastasis with a focal FDG uptake on left proximal femur. This lesion was interpreted as fibrous dysplasia based on MRI in addition to the plain radiographs. We conclude that MRI in addition to radiography may help to differentiate fibrous dysplasia mimicking metastasis on PET/CT in the patients with malignancy.

Epidermolytic keratosis palmaris is a rare disease which shows clinical findings of Unna Thost keratoderma and histopathologic of epidermolytic hyperkeratosis. We report herein a case of epidermolytic keratosis palmaris et plantaris in a 16-month-old female baby. Light microscopy shows marked hyperkeratosis, large irregular keratohyalin granules, and large clear spaces in the granular and upper spinous layers. Eletron microscopic findings shows that the clear spaces are areas of cytoplasm filled with a fibrillar material and cellular organelles. Abnormal clumping of tonofilament and keratohyalin is also present.

Background: Fine needle aspiration and biopsy(FNAB) has known the most accurate test(about 90%) in the preoperative evaluation of patients with a thyroid nodule. The false negative findings of thyroid cancer by FNAB are mainly due to the aspiration of cystic fluid in cystic degeneration of thyroid cancer and the ipossibility of differentiation between follicular adenoma and carcinoma by aspiration or FNAB because of the failure to evaluate the capsule invasion or angioinvasion of the tumor. Actually more than 80% of the nodules are found as benign nodules in aspiration or FNAB and the findings of follieular lesions are found about half of the samples tested, so limiting the cancer incidence in surgically resected samples up to 50% of the surgical resection. Sa reasonable guidelines to manage the benign nodules on aspiration or FNAB are needed which can select the maligna~nt nodules with false negative findings on aspiration or FNAB. We tried to evaluate whether the thyroxine suppression therapy can increase the malignancy rates on thyroidectomy, Methods: We treated the benign thyroid nodules in FNAB with thyroxine for 1 year and cornpared the nodule volume change before and after treatment (every 6 month) with ultrasonogram. We performed thyroidectomy on 1~7 thyroid nodules wbich showed less than 50% decrease of nodule volume after 1 year of thyroxine suppression therapy. Results: The results were as follows. 1) Of all 17 patients, surgical resection revealed malignant thyroid nodule(Group I) in 10 cases (58.82%, papillary cancer. 6 cases, follicular cancer: 4 cases) and benign thyroid nodule(Group II) in 7 cases(41.18%, follicular adenoma: 4 cases, adenomatous goiter: 3 cases). 2) Between group I and II, there was no significant differences in serum T, T and TSH levels before and after thyroxine suppression therapy. Also, there were no significant difference in TSH suppression % between group I and group II(5.60+5.39%, 14.64+11.48%, respectively). 3) Thyroid nodule volume decrease percent before and after thyroxi~ne therapy showed no significant difference between group I and group II (124.80+54.18% vs 159.42+79.82%, p>0.05). Conclusion: Our data suggested that the benign thyroid nodules on aspiration or FNAB which were not suppressed in volume after thyroixine therapy revealed more than 50% incidence of malignancy on surgical resection, so these nodules were highly reeommended to surgical exploration.

PURPOSE: Oxaliplatin is a third-generation platinum compound, and it has no nephrotoxicity and has reduced bone marrow toxicity. Cancer cells that are resistant to cisplatin are sensitive to oxaliplatin. Oxaliplatin is used widely for the treatment of colon cancers. Recently, oxaliplatin was reported to inhibit the expression of survivin, which protects cell apoptosis. However, there are no reports on the expressions of survivin variants and the changes in intracellular localization of survivin in cancer cells. We studied the expression of survivin caused by oxaliplatin in HCT116 colon cancer cells, and we observed the localization of survivin in the mitotic phase. METHODS: We treated the HCT116 colon cancer cells with 2.0 micrometer of oxaliplatin, and we studied the expressions of survivin protein, and survivin mRNA variants, as well as the changes in intracellular localization, by using the Western blot method, RT-PCR, immunocytochemistry, and flowcytometry. RESULTS: Oxaliplatin inhibits the expression of the survivin protein and survivin mRNA in HCT116 colon cancer cells. The expression of the survivin-2B variants, which have no antiapoptotic activity but control cell mitosis by localization on a microtubule, is reduced continuously 2 days after treatment with oxaliplatin. In immunocytochemistry, expression of survivin in the cytoplasm is reduced and especially is not expressed in microtubules and contractile rings. CONCLUSION: One of the mechanisms of oxaliplatin is to inhibit the expression of and to change the localization of survivin. Based on these results, we suggest that changes in the expression of survivin variants and in their localization are two effects of oxaliplatin.

The long term administration of anti-convulsants on children with convulsive disorders may cause osteomalacia, depending on the dosage, duration, type and combination of anti-convulsants administred. Fifteen children, comprising 10 male and 5 female, dignosed with convulsive disorders and administered with phenobarbital for a long term period of more than 9 months but less than 84 months and 15 healthy children of a similar age-group were selected for the investigation the density of she spinal backbone of each individual was measured by means of the "QDR-2000 X-ray bone densitometer's (made by Hologic company) which uses the double energy X-ray absorption technique. The levels of serum calcium, phosphrus and alkaline phosphatase for each child were also measured for comparative analysis. The results were as follows: 1) The mean bone density for the healthy group of chlidren was 0.69+/-0.09g/cm(2) and that for the group of children administered with phenobarbital was 0.59+/-0.07cm(2) indicating a significant decrease in density for the latter group (p<0.05). 2) As for the relationship between the duration of phenonbarbital and the decrease in bone mineral density, 5 of 6 patients(83%) administered with phenobarbital for more than 4 years showed a decrease in bone mineral density and 5 of 9 patients (56%) administered with phenobarbital for less than 4 years showed a decrease in bone mineral density. 3) the mean vitamin D level for the healthy group of chlidren was 26.8+/-2.5pg/ml indicating a significant decrease in vitamin D3 level for this group(p<0.05). 4) The mean serum alkaline phospatase evel for the health group of children was 240+/-50u/L and 462+/-110u/L for those administered with phenobarbital. This indicate a significant increase in ALP for phenobarbital group(p<0.05). 5) The posphorus and calcium levels were within the normal range for all the groups of children.

BACKGROUND AND OBJECTIVES: Percutaneous intervention has become an established technique in the treatment of peripheral arterial obstructive disease. This study was performed to evaluate the procedural success and long-term outcome of percutaneous intervention of the superficial femoral artery (SFA), and to determine the factors that influence the long-term outcome. SUBJECTS AND MEHTODS: Eighty-eight consecutive lesions, in 76 subjects (mean age 65) with chronic lower limb ischemia and SFA obstruction, diagnosed with angiography were included in this study. The angiographic success was defined as residual stenosis <30% and the clinical success as an improvement by at least one clinical category. The clinical patency was defined as an absence of symptom recurrence and target lesion revascularization during the follow up period. The predictors of the outcome were also determined. RESULTS: Balloon angioplasty only was performed in 39 lesions and thrombolysis only in 2, whereas stenting was performed in 47 lesions. Seventy four of the 88 attempts (84%) at recanalization were angiographically successful, while 73 (83%) experienced clinical improvement. The twelve month patency was 67%. Critical ischemia (versus intermittent claudication)(relative risk 4.2, p=0.020) and renal failure (relative risk 4.1, p=0.016) were independent negative predictors of the patency. CONCLUSION: Percutaneous intervention of the SFA yielded a high procedural success rate, with an acceptable long-term outcome. Symptoms of critical ischemia and renal failure were predictive of a low long-term patency.
