Intradiploic epidermoid cysts, like epidermoid cysts in other cranial locations, are rare. Approximately 100 intradiploic epidermoids have been reported, involving all of the cranial bones in proportion to their relative sizes1). Over half erode through both tables of the cranium, creating variably sized areas of unprotected brain beneath the soft tumor. We report a case of an intradiploic epidermoid cyst of the right parietal bone that was found after minor head trauma.

PURPOSE: We investigated the clinical course of infants with congenital heart disease (CHD) who experienced thyroid dysfunction within 100 days of birth. METHODS: We performed retrospective medical reviews of 54 CHD patients (24 male patients) who underwent a thyroid function test (TFT) between January 2007 and July 2016. Data were collected on birth history, diagnosis of CHD, underlying chromosomal or genetic abnormalities, medication history, surgery, ventilator care, and exposure to iodine contrast media (ICM). Results of neonatal screening tests (NSTs) and TFTs were reviewed. RESULTS: A total of 36 patients (29 transient, 7 permanent) showed thyroid dysfunction. Among the seven patients with permanent hypothyroidism, three had an underlying syndrome, three showed abnormal NST results, and one was admitted to the intensive care unit for macroglossia and feeding cyanosis. We found that infants with transient thyroid dysfunction had a lower birth weight and were more commonly exposed to thyroid disrupting medication and/or ICM. However, these risk factors were not significant. A total of 8 patients with a history of ICM exposure showed thyroid dysfunction. Excluding 3 patients with elevated thyroid stimulating hormone before ICM exposure, 5 patients recovered from transient thyroid dysfunction. CONCLUSIONS: We observed thyroid dysfunction in two-thirds of CHD infants (53.7% transient, 13.0% permanent) who had risk factors and received TFT screening within 100 days, despite normal NSTs. Further studies with larger sample sizes are required to revise the criteria for TFT screening in CHD infants.

OBJECTIVE: To evaluate the effects of low dose estrogen menopausal hormone therapy on cardiovascular system METHODS: This study categorized 95 postmenopausal women between March 2004 and August 2004. Thirty patients of estrogen therapy group, fifteen patients of estrogen-progestin therapy group, fifteen patients of low-dose estrogen therapy group, and fifteen patients of low-dose estrogen-progestin therapy group were divided. Remaining 20 patients served as control group which did not receive the hormone treatment. The blood pressure, pulse rate, lipid profile, and NO metabolites and antioxidant activity of plasma and urine were measured. RESULTS: Diastolic blood pressure was lower in hormone treatment group than control group's. Although it was not significant, the total cholestrol and LDL-cholestrol in the plasma of treatment group were lower than those of the control group while HDL-cholestrol were higher. Triglyceride in the plasma of treatment group was higher. Changes of blood pressure, pulse rate and lipid profile in low-dose group were similar to those of conventional standard dose. The plasma concentration of NO metabolites in treatment group was higher. Also, the plasma concentration of NO metabolites in low-dose group was similar to that of conventional dose. CONCLUSION: A low-dose hormone therapy was expected to bring about the improvement of endothelial cell dependent vascular reactivity like conventional dose, resulting in the reduction of diastolic blood pressure, the improvement of lipid profile, and an increase in plasma concentration of the NO metabolites. A low-dose hormone therapy may thus presumably provide beneficial effects on cardiovascular system.

BACKGROUND: Since the introduction of warm blood cardioplegic myocardial protection, the results of numerous clinical trials have been reported. However , the increased reliance oncrystalloid cardioplegia with longer cross clamp time, the controversies surrounding the issue of right ventricular protection with retrograde cardioplegia, and problems of securing a good operative field of vision have all been pointed out as unresolved. To overcome these shortcomings, Antonio et al, in 1995 published the use of intermittent warm blood cardioplegia by admixing potassium only with good clinical results. The obj ectives of the current investigation were to assess the effects and applicability of warm blood cardioplegia with potassium only. MATERIAL AND METHOD: From May of 1998 to January of 1999, the results of coronary surgery or open heart surgery in 70 patients under intermittent warm blood potassium only cardioplegia were compared with the results of 70 case matched patients undergoing similar operations with intermittent cold blood cardioplegia. RESULT: The amount of cardioplegic solution required during cardiopulmonary bypass(1463+/-68.0 min, 3584+/-179 min, p<0.001), the time to recovery of consciousness postoperatively(3.5+/-0.4 min, 4.9+/-0.8 min, p=0.044), intubation duration(10.8+/-0.8 hr , 13.2+/-0.6 hr , p=0.017), and the inci-dence of rrhythmia requiring the use of lidocaine(75.2+/-6.8 mg, 114.5+/-7.2 mg, p=0.006), which were found to be less in the warm potassium only group were statistically significant. However, the differences in postoperative cardiac enzymne elevation and postoperative mortality and morbidity were statistically insignificant. CONCLUSION: The current study showed warm intermittent potassium only blood cardioplegia to be at least equally effective as cold intermittent blood cardioplegia in providing myocardial protection. Furthermore, the reduction in cardiopulmonary bypass, mental recovery and intubation times strongly support the use of this method for intraopertaive myocardial protection.

PURPOSE: To correlate the mammographic and ultrasonographic findings with the pathologic results in women undergoing hormone replacement therapy (HRT), and to determine the characteristic clinical, mammographic or histologic findings of breast cancer in these patients. MATERIALS AND METHODS: Twenty-five breast lesions in 25 patients aged 44-65 (mean, 55.5) years undergoing HRT were surgically removed due to abnormal mammographic findings or the presence of palpable masses. Mammograms in all patients and ultrasonograms in 23 were retrospectively analyzed in terms of the shape and margin of the mass, and microcalcifications, and the imaging findings were correlated with the pathologic results. As a control group, 45 cancer patients not undergoing HRT were selected. Using the student t test, detection methods, tumor size, mammographic findings, and the proportion of intraductal cancers were compared between the two groups. RESULTS: Surgical excision revealed ten benign lesions (four fibroadenomas and six cases of fibrocystic change) and 15 cancers (three intraductal and twelve invasive ductal cancers). Abnormal findings at mammography were a mass in 16 cases, clustered microcalcifications in seven, and a mass with microcalcifications in two. Mammography showed that all four circumscribed masses were benign. Five of seven ill-defined masses (71%) and all six spiculated masses were malignant. Three of seven cases (43%) with microcalcification, and both with a mass and microcalcification, were malignant. In two cases in which ultrasonography revealed cystic lesions, histologic examination showed that fibrocystic change had occurred. Compared to non-HRT-related cancers, HRT-related cancers were more often detected by mammography (60% vs 16%; p <0.001), smaller (17 mm vs 24 mm, p <0.01), showed microcalcification only (20% vs 13%; p <0.05), and were intraductal (20% vs 7%; p <0.01). CONCLUSION: In patients with HRT, mammographic findings of an ill-defined or spiculated mass, or one with microcalcifications, were associated with breast cancer. Compared to non-HRT-related cancers, breast cancers in patients undergoing HRT tend to manifest more frequently as a mammographic abnormality, and to be intraductal.

BACKGROUND/AIMS: Carcinoid tumors are often indolent asymptomatic tumors, however significant proportions are malignant. The patients with these tumors have usually been treated by radical excision. Recently, small gastrointestinal carcinoid tumors can be easily be detected with increasing use of endoscopy and surgical treatment has been questioned. We evaluate clinical characteristics of gastrointestinal carcinoid tumors and clinical usefulness of endoscopic resection in treatment of gastrointestinal carcinoid tumors. METHODS: We reviewed the medical records of 37 cases of gastrointestinal carcinoid tumors over the past three years in our instituide. RESULTS: The peak incidence was in the 5th decade and slight male predominance. The most comgastrointestinal carcinoid tumors were diagnosed by endoscopy with biopsy. Twenty-six cases of carcinoid tumors of size less than 15 mm have been safely treated with endoscopic resection. All of the patients are alive and clinically free of disease during 23 months after endoscopic resection. CONCLUSIONS: Recently, the detection of small carcinoid tumors in gastrointestinal tract, especially in rectum, is increasing with frequent use of endoscopy. Endoscopic resection was found to be useful and safe for treatment of small gastrointestinal carcinoid tumors.
