The term malignant mesenchymoma has been applied to those tumors of the soft tissue of mesenchymal origin which are composed of tumor cells differentiating into two or more unrelated malignant forms in addition to the fibrosarcomatous element. Recently authors experienced a case of malignant mesenchymoma in the right axillary area. Microscopically the sarcoma revealed multiple pattern of differentiation, including liposarcoma, malignant schwannoma, fibrosarcoma, malignant fibrous histiocytoma and rhabdomyoblastoma. The presence of rhabdomyblastic cells were proved by immunochemical study utilizing desmin. This patient was treated with surgical excision and radiation.

BACKGROUND: Thyroid status in uremia is still inconclusive due to the complexicity of the system. No single pathogenetic event may explain the thyroid function abnormalities in end stage renal disease (ESRD). Defects at all levels of the hypothalamic-pituitary-thyroid axis have been identified. Regarding the thyroid dysfunction in ESRD it is well recognized that the TSH response to TRH is blunted and serum concentrations of thyroid hormones are decreased in patients with ESRD. Whether or not on maintenance hemodialysis. Restoration of renal function with renal transplantation resulted in normalization of all parameters of thyroid function with exception of blunted TSH response to TRH. We evaluated the long-term changes of the thyroid function in 10 patients to know whether the thyroid function and the hypothalamo-pituitary axis were improved with the recovery of the renal function under maintenance low-dosage steroid administration after renal transplantation. METHODS: These tests were performed during the morning in the fasting state in 10 ESRD patients before, 1 month and 6 years after renal transplantation (RT). Thyroid function tests. Serum T3, T4 were measured by RIA kit and serum TSH was measured by IRMA kit. TRH stimulation test. Serum blood samples were obtained 0, 30, 60, 90, 120 min after TRH (400microgram) administration. Statistical analysis. All grouped data were expressed as mean+/-SD. Student t-test was used to assess the statistical difference between any two means. RESULTS: 1) The mean basal level of serum T3 was reduced in ESRD patients (53.6+/-33.2ng/dL) and increased to the low normal level 1 month after RT (87.8+/-25.4ng/dL), improved to the normal level 6 years after RT (116.3+/-28.8ng/dL). 2) The mean basal level of T4 was within normal range before RT (5.9+/-1.1microgram/dL), after 1 month (6.2+/-1.2microgram/dL) and after 6 years (6.5+/-1.4microgram/dL) of RT. 3) The mean basal level of TSH was within normal range before RT (2.0+/-1.2microU/mL), after 1 month (1.1+/-0.7microU/mL), and after 6 years (0.7+/-0.5microU/mL) of RT. Rut the mean TSH level of 6 years of RT was significantly decreased within the normal range. 4) In ESRD the TSH response to TRH was blunted, had a diminished peak and delayed fall before RT. After 1 month of RT, the TSH response to TRH was persistently blunted, however showed more rapid fall of TSH. After 6 years of RT, the TSH response to TRH normalized, but the absolute level of TSH and the peak level of TSH to TRH were less than before and after 1 month of RT. CONCLUSIONS: The abnormalities of thyroid hormones in uremic patients were improved partially after 1 month of RT and almost completely after 6 years of RT. But the level of T3H and the peak level of TSH to TRH were low within normal range, these results may be a direct consequence of low-dosage and long-term glucorcorticoid administration.

Primary retroperitoneal mucinous tumor is very rare. In the worldwide literature, only 14 cases have been reported. Herein, we report two cases of retroperitoneal mucinous tumor found at laparotomy. The patients were females, aged 24 and 21 years, respectively. They had bilateral normal ovaries. Histologically, one was mucinous cystadenoma and the other showed borderline histology. The connective tissue wall resembling ovarian stroma was noted in one case. The pathogenesis was discussed.

In order to evaluate the confounding factors of neurobehavioral tests and the neurobehavioral effects in the workers exposed to organic solvents, NCTB was carried out on 100 workers. 46 workers had never been exposed to neurotoxic substances, and the others were being exposed to the solvents, mainly toluene. Simple reaction time, digit symbol, Santa Ana dexterity test and persuit aiming were different with age in non exposure group. Simple reaction time was carried out well in males, and digit symbol and persuit aiming were in females. There was no difference at educational level when the subject was educated over 12 years. Santa Ana dexterity and Benton visual test differed according to exposure level to toluene, however simple reaction time didn't. The acute neurotoxic effect was not excluded in this study. But, NCTB could be used to evaluate and prevent neurobehavioral changes in workers exposed to neurotoxic solvents in Korea.

Although the mediastinum is the second favorite location of primary teratoma in adults, primary malignant teratoma in mediastinum is rare in incidence. Malignant teratoma includes teratocarcinoma, immature teratoma and malignant transformation in benign teratoma. The latter is rarer than others types, and undifferentiated or squamous cell carcinoma are the major incidence. We experience a case of unique adenocarcinoma composed of signet ring cells in mature teratoma of mediastinum and brief review of the literatures are included.

Background: Brain MRI may unexpectedly display abnormalities in splenium of the corpus callosum
(SCC). However, the clinical implications of this lesion are unclear and are not always consistent
with ischemic infarctions. We performed this study to clarify the clinical and radiological implications
in patients with SCC lesions. Methods: We retrospectively reviewed consecutive patients with MRIreported
SCC changes between 2009 and 2012. We analyzed clinical and radiological findings,
etiologies, cognitive impairment, and clinical outcomes. Results: We found 30 patients (16 females;
mean 50.5 years) who had SCC lesions on MRI. Confusion was the most common clinical finding
in 50% of cases. Cerebral infarction was the most common etiology (50%). The most consistent
SCC changes on MRI were low signal in T1WI, high signal on T2WI and FLAIR, and high signal
on DWI. We classified SCC lesions into in situ SCC lesions (SCC only) and multiple (SCC plus)
lesions for patients with multiple lesions. The clinical symptoms of SCC only lesions were relatively
mild. Cognitive functions were evaluated by Mini Mental State Examination (MMSE) and clinical
dementia rating (CDR) scale at the time of discharge and patients with SCC only lesions showed less
impaired cognition compared with those with SCC plus lesions. Clinical outcomes were evaluated
by the modified Rankin scale at 1 month and patients with SCC only lesions revealed good clinical
outcomes compared with those with SCC plus lesions.
Conclusions: MRI-reported SCC lesions may have heterogeneous etiologies and present with various
symptoms. The clinical course and outcome are relatively good, particularly in small isolated and
oval shaped SCC lesions.

Background & Objective: Hiccups is a disabling condition of lateral medullary infarction (LMI).
Unlike other symptoms of LMI, the anatomical lesions of hiccups are not well known. Few studies
have evaluated the relationship between the lesional location of LMI and hiccups. We performed this
study to correlate hiccups and magnetic resonance imaging (MRI)-based lesional location in pure
LMI. Methods: Between January 1997 and February 2013, we identified 24 patients with pure LMI
who presented with hiccups in addition to typical lateral medullary syndrome. Sixty six pure LMI
patients without hiccups were included as a control group. Clinical and radiologic findings were
compared between the two groups. MRI-identified lesions were classified rostrocaudally as rostral,
middle and caudal, and horizontally as typical, ventral, large, lateral and dorsal. Results: The pure
LMI patients with hiccups had significantly more frequent aspiration pneumonia (P = 0.001) and
longer hospital stay (P = 0.03). The patients with hiccups significantly more often had dorsal rather
than ventral lesion at horizontal levels (P = 0.012). But, there were no rostro-caudal differences at
vertical levels (P = 0.162).
Conclusions: We suggest that pure LMI associated with hiccups often locates in the dorsal medulla
at horizontal correlation. This MRI-based comparative study has advanced the understanding of the
neural substrate for hiccups in LMI, and indicates that hiccups become predictable when specific
lesional locations in the lateral medulla are considered.

We experienced a case of vitamin B12 unresponsive methlymalonic acidemia in a 4 day old female, who had poor feeding, dehydration with metabolic acidosis, and hyperammonernia and died at 7 days of age. Diagnosis was made by gas chromatography and mass spectrometry, and this case is probably a methylmalonyl CoA mutase apoenzyme deficiency type.

9.Radiologic Findings of Pancreatic Cystic Neoplasms.
Korean Journal of Medicine 2014;87(3):261-269
With the widespread use of radiologic modalities such as ultrasonography (US), computed tomography (CT), and magnetic resonance imaging (MRI), cystic neoplasms of the pancreas are being increasingly detected; however, developing an accurate characterization and making a differential diagnosis are difficult because of their overlapping morphologic characteristics. Serous cyst adenoma is a common benign neoplasm that is typically observed as a multi-cystic mass or lobulated cyst with or without internal septation. In comparison, mucinous cystic neoplasms appear as smooth cystic tumors with or without internal septation. Finally, intraductal papillary mucinous neoplasms of the pancreas are pleomorphic cystic lesions or clubbed fingerlike tubular structures. These typical imaging findings can help clinicians differentiate cystic neoplasms of the pancreas.

PURPOSE: To compare the effect of breast milk containing fortifier with preterm formula on bone mineral metabolism in premature infants, we evaluated the state of bone mineralization, biochemical alteration and the frequency of rickets during the first five months of life. METHODS: Fourteen fortified breast milk-fed infants and eleven preterm formula-fed infants who were born at Il-Sin Christian Hospital from August, 1996 through July, 1997, were studied. The breast milk-fed group received human milk fortifier. The intake of Ca, P, Mg, protein, and fat was calculated at one month of age. Birth weight and weight at one, two and five months of age were measured. Serum Ca, P, alkaline phosphatase and 25-hydroxyvitamine D were measured at one month of age, and the wrist received X-ray examinations monthly. Total body bone mineral content was measured by Dual energy X-ray absorptiometry (Lunar WI) at two and five months of age. RESULTS: The two groups were similar in birth weight, gestational age, and weight at one, two and five months of age. Enteral Ca, P, protein, Mg, and fat intake, and urinary excretion of Ca, P were similar among the two groups. Serum Ca, P, ALP and 25-hydroxyvitamin D were not different. Occurrence of rickets and bone mineral content were similar among the two groups. CONCLUSION: Fortified breast milk-fed infants and preterm formula-fed infants showed no difference in total body bone mineral content and occurrence of rickets. Ultimately, we could enhance the advantage of breast milk fed to premature infants by adding fortifier.
