Benign tumors and tumor like lesions in the foot are uncommon and those that are malignant are rare. Metastatic cancer of bone distal to the knee and elbow is unusual. By contrast, non-tumorous lisions that cause swelling, pretuberance, or deformity are common. Fifty two cases of tumors on foot were treated at our department from Jan. 1970 to Dec. 1991, we have treated fifty two cases of foot tumor and analysed their clinical characteristics. Bone tumors were more frequent than soft tissue tumors (2:1). Among soft tissue tumors benign tumors were frequent than malignant(1.4:1), and fibroma was the most frequent tumor(30%). Benign soft tissue tumors occured frequently at Edward and Michael's Zone 3(57%). Benign bone tumors has higher incidence than malignant(20:1). Osteochondroma was the most frequent tumor (48%). Predilection sites for osteochondroma and enchondroma of foot was distal phalanges and mitatarsal bone, respectively.

Syndrome of inappropriate antidiutetic hormone(SIADH) secretion is the most common cause of hyponatremia in clinical medicine. Before diagnosis of the SIADH is made, other causes for a decreased diluting capacity and nonosmotic stimuli for AVP release need to be rule out. Disorders associated with SIADH can be divided into 4 major etiologic groups: malignancies, pulmonary diseases, central nervous disorders, and drugs. A 45-year-old woman was admitted due to maculopapular skin eruption and fever after taking medications for fever and myalgia. Generalized tonic clonic seizure was developed nine days later, and laboratory results showed marked hyponatremia. During the evaluation, treatment, and subsequent follow-up, the diagnosis of SIADH was confirmed, but the definitive cause was obscure. With fluid restriction, sodium replacement and demeclocycline therapy, she recovered completely 6 months later. We suggest that the SIADH might be related to drug-induced generalized maculopapular rash via menmgitis-like reaction in CSF as one of systemic adverse side effects to drugs rather than direct effect of related drugs.

PURPOSE: This study was conducted to know the applications and limitations of three dimensional volume rendering virtual endoscopy of the ossicles using a multi-row detector CT. MATERIALS AND METHODS: This study examined 25 patients who underwent temporal bone CT using a 16-row detector CT as a result of hearing problems or trauma. The axial CT scan of the temporal bone was performed with a 0.6 mm collimation, and a reconstruction was carried out with a U70u Sharp of kernel value, a 1 mm thickness and 0.5-1.0 mm increments. After observing the ossicles in the axial and coronal images, virtual endoscopy was performed using a three dimensional volume rendering technique with a threshold value of -500 HU. The intra-operative otoendoscopy was performed in 12 ears, and was compared with the virtual endoscopy findings. RESULTS: Virtual endoscopy of the 29 ears without hearing problems demonstrated hypoplastic or an incomplete depiction of the stapes superstructures in 25 ears and a normal depiction in 4 ears. Virtual endoscopy of 21 ears with hearing problems demonstrated no ossicles in 1 ear, no malleus in 3 ears, a malleoincudal subluxation in 6 ears, a dysplastic incus in 5 ears, an incudostapedial subluxation in 9 ears, dysplastic stapes in 2 ears, a hypoplastic or incomplete depiction of the stapes in 16 ears and no stapes in 1 ear. In contrast to the intra-operative otoendoscopy, 8 out of 12 ears showed a hypoplastic or deformed stapes in the virtual endoscopy. CONCLUSION: Volume rendering virtual endoscopy using a multi-row detector CT is an excellent method for evaluation the ossicles in three dimension, even though the partial volume effect for the stapes superstructures needs to be considered.

Hashimotos thyroiditis has been associated with a various autoimmune disorders. The immunologic mechanisms involved in the pathogenesis of these disorders have not always been thought to be the same. Although it was demonstrated that there were high prevalence of abnormal thyroid function and autoantibody in autoimmune hemolytic anemia(AIHA) and Fisher-Evans syndrome(FES), AIHA combined with Hashimotos thyroiditis is rare in Korean literature. It was suggested that a common immunologic mechanism may be involved in the pathogenesis of both disease and the possibility of multiple autoimmune syndrome might present in autoimmune hematologic disorders. We experienced a 74-year old woman with a 12-year history of a hypothyroidism due to Hashimotos thyroiditis was hospitalized with sudden development of warm AIHA with positive Direct & Indirect Coombs test and pericardial effusion. Her thyroid function test showed subclinical hypothyroidism with the maintenance dosage of levothyroxine(100pg/day). With glucocorticoid and plasmapheresis, AIHA and pericardial effusion were corrected successfully. It is suggested that the prudent immunologic study is needed for the anemia developed in patients with Hashimotos thyroiditis with or without hypothyroidism.

PURPOSE: Estrogens control the development and cell proliferation of various tissues including the normal mammary epithelial cells, where they induce the expression of the immediate and delayed hormone-responsive genes. The proliferative effects of estrogen have been attributed to its ability to increase the expression of the key cell cycle regulatory genes responsible for cell cycle progression. However, the regulation of cell proliferation is only one aspect of estrogen function. It has also been well documented that estrogen plays a critical role in the etiology and progression of human breast and gynecological cancers. This tumorigenic effect of estrogen might be associated with its anti- apoptotic activities such as of Bcl-2 induction. The aim of this study was to clarify the role of E2IG5, which is an estrogen-induced downstream effector molecule, in breast cancer cell lines. RESULTS: This study shows that E2IG5 is a pro-apoptotic protein that is localized to the mitochondrial membrane via two distinct transmembrane domains. When over-expressed, it induces a mitochondrial permeability transition with the resultant of release cytochrome c and caspase activation. However, three out of four breast cancer cell lines lost their estrogen dependence of E2IG5 expression, which suggests the possible involvement of E2IG5 in the development of breast cancer. CONCLUSION: These results suggest that breast cancer cells may loose their pro-apoptotic signals and selectively use the proliferative mechanism of estrogen, which drives the normal mammary epithelial cells to transform into cancer cells. Further studies using breast cancer tissues will be needed.

Diabetic insipidus may first present before, during or immediately after pregnancy. Pregnancy serves as a physiologic provocation test that unmasks latent diabetes insipidus. It may explain the very rare first occurrence of diabetes insipidus in the pureperium. Central diabetes insipidus occurring after delivery associated with a catastrophic delivery and postpartum hypopituitarism is more frequent entity. We recently experienced central diabetes insipidus patient, aggrevated polyuria and polydipsia after total hysterectomy due to cervical carcinoma, who had interesting past history of severe polyuria and polydipsia developed during puerperium of 1st pregnancy, 14 years ago. She have had quiet normal pregnancy and there was no definite postpartum complication of pregnancy at that time. There were no change of polyuria and polydipsia during and after second pregnancy and 2 another pregnancy terminated artificially compare to puerperium of 1st delivery. She has intact anterior pituitary gland functinally and anatomically, but the posterior pituitary hyperintense signal with pre-enhance Tl-weighted imaging was absent on MRI.

PURPOSE: To evaluate the efficacy of computed tomography(CT) in detecting pericardial adhesion. MATERIALS AND METHODS: CT of 32 patients with 'redo-valve surgery' was retrospectively evaluated for the location and appearance of their surgically confirmed pericardial adhesion. CT of 20 cases without cardiac or pericardial disease was reviewed as normal control. RESULTS: Nodular increased density at the site of adhesion between the sternum and the right atrium(RA) or ascending aorta(n=10), retrosternal dirty fat(n=10), obliteration of the pericardial fat(n=28), cardiac contour change with or without nodular epicardial fat accumulation(n=10), diffuse pericardial thickening(n=14), and pericardial calcification(n=13) were considered to be important findings. We also noticed an additional findings of beak-like projection of RA appendage(n=13), but was considered less significant because they were also observed in 4 normal subjects. CONCLUSION: CT scan is an effective, simple, and noninvasive method for predicting pericardial adhesion that may be occurred after redo-valve surgery.

PURPOSE: Despite numorous reports on the relationship between the level of carcinoembryonic antigen (CEA) in gall bladder bile and liver metastasis in colorectal cancer, no similar studies have been carried out for gastric carcinomas. We, therefore, undertook the present study to establish the relationship between the gall bladder bile CEA and liver metastasis as well as the post-operative survival rate in gastric carcinoma patients with curative resections. MATERIALS AND METHODS: In 373 gastric cancer patients (252 males, 121 females, age 21~76 years) operated on at Kosin University Hospital between 1989~1996, the CEA concentration in the gall bladder bile was determined during the operation and the value was related to the rates of post-operative survival and liver metastasis during follow-up period. RESULTS: The overall rate of patient survival decreased gradually with increase in TNM stage. The 13-year post-operative survival rates for stages Ia, Ib, II, IIIa, and IIIb were 95.7%, 92.5%, 79.9%, 50.9%, and 43.3%, respectively, and the 10-year survival rate for stage IV was 22.6%. The patients with a high (> or =10 ng/ml) biliary CEA showed a significantly lower rate of survival than those with a low (<10 ng/ml) biliary CEA. The 13-year cumulative survival rate was 55.4% for the high CEA group and 76.5% for the low CEA group (P<0.01). Also, the patients with a high biliary CEA showed a significantly higher rate (11.5%) of liver metastasis than those with a low biliary CEA (1.9%) (P<0.000). In patients with TNM stages (I and II), the CEA level did not affect the post-operative survival rates (95.4% and 87.7% in the high and low CEA groups, P>0.10), but in those with high TNM stages (III and IV), the survival rate was significantly lower in the high CEA group (25.9%) than in the low CEA group (57.8%) (P<0.05). CONCLUSION: These result suggest that the gall bladder bile CEA level obtained in an advanced-staged gastric cancer operation may be used in predicting the post-operational survival rate and in sorting out patients with a high risk for cancer recurrence, especially in the liver area.

We report a case of Lennox-Gastaut syndrome successfully treated by the removal of hippocampal gangliocytoma. A17-year-old girl was admitted due to intractable tonic seizure, generalized tonic clonic seizure, and frequent fallingdespite the administration of polypharmacotherapy. She was mentally retarded and had developmental delays. She had the first seizure at the age of 12 months and the pattern of seizures seemed to be drop attacks. Electroencephalogram (EEG) showed background slowing of about 7 Hz, multifocal spike and wave, and generalized spike and wave complex-es (1.5~3.5 Hz). Magnetic resonance image (MRI) revealed a small polycystic mass in the left parahippocampal gyrus and hippocampal atrophy. A left hippocampectomy and total resection of the tumor was performed. Histopathologically, the cysts were identical to gangliocytoma. Sixth months later, the frequency of seizures decreased to once a month No seizures have been reported since August 1998.

The authors report a case of growing fracture of the skull, also called as leptomeningeal cyst, in a young boy who presented with symptoms of skull defect, headache, and pulsating mass on right posterior parietal area. Successful duroplasty and cranioplasty with autogenous bone were performed resulting in disappearance of all symptoms. The most significant factor contributing to the growing fracture is an underlying dura tear. A brief review of the relevant literature is also presented.
