We report two cases of hyalinizing trabecular carcinoma (HTC) of the thyroid gland. These two patients were euthyroid women aged 36 and 65 years of age. The tumors were encapsulated and measured 0.8 and 4.0 cm in diameter, respectively. Histologically, the tumors were composed of a compact proliferation of cells in a lobular and trabecular pattern with an intervening hyalinized, fibrotic vascular stroma. Occasionally the cells were arrayed in microfollicles. Multiple and serial sections showed cords of tumor cells invading into the capsule in both cases and vascular invasion in one case. These findings suggested that HTCs are a malignant counterpart of hyalinizing trabecular adenoma, similar to conventional follicular tumor. Positive immunostaining of tumor cells for thyroglobulin and negative staining for high molecular weight cytokeratin, cytokeratin 19, neuron specific enolase, chromogranin, and synaptophysin allowed distinction from medullary carcinoma. Even though HTCs are an heterogeneous group of tumors, the present two cases are probably variants of follicular carcinoma rather than papillary carcinoma.

OBJECTIVES: Estimation of the anterior lower uterine segment (LUS) thickness difference who underwent prior cesarean delivery measured with transvaginal sonography at or after 36 gestational weeks (sonographic thickness) and a ruler during elective cesarean section (operation thickness) Methods: One hundred sixty women who underwent prior cesarean delivery had the thickness of their LUS measured with transvaginal sonography at or after 36 gestational weeks. The LUS thickness was measured with a ruler during elective cesarean section. We compared group I whose LUS was fairly well visualized 4 cm or more from the uterine cervix to group II which had less than 4 cm. RESULTS: The mean sonographic thickness of LUS was 1.7 0.8 mm and that of operation thickness was 1.9 0.5 mm. The mean difference of the two (thickness difference) was 0.5 0.5 mm. In 31.3% the sonographic thickness was same as the operation thickness and in 70.7% of the total with 0.5 mm or less difference, the sonographic thickness could be regarded as accurate. The thickness difference with the sonographic thickness with 2 mm or more was smaller than those with 1 mm or less (0.4 0.5; 0.6 0.6) and that of group I was smaller than that of group II (0.4 0.4; 0.9 0.6) (p< .05). CONCLUSION: The thickness difference was 0.5 0.5 mm and it was smaller when the LUS thickness is 2 mm or over, clearly visible 4 cm or over from the cervix.

BACKGROUND: Apoptosis plays a role in the development of pleural effusion. Caspase-cleaved cytokeratin 18, a marker for epithelial cell apoptosis, was evaluated in pleural effusion. METHODS: A total of 79 patients with pleural effusion were enrolled. The underlying causes were lung cancer (n=24), parapneumonic effusion (n=15), tuberculous effusion (n=28), and transudates (n=12). The levels of M30, an epitope of caspase-cleaved cytokeratin 18, were measured in blood and pleural fluids using enzyme-linked immunosorbent assay along with routine cellular and biochemical parameters. The expression of M30 was evaluated in the pleural tissues using immunohistochemistry for M30. RESULTS: The M30 levels in pleural fluid were significantly higher in patients with tuberculosis (2,632.1+/-1,467.3 U/mL) than in patients with lung cancer (956.5+/-618.5 U/mL), parapneumonic effusion (689.9+/-413.6 U/mL), and transudates (273.6+/-144.5 U/mL; all p<0.01). The serum levels were not significantly different among the disease groups. Based on receiver operating characteristics analysis, the area under the curve of M30 for differentiating tuberculous pleural effusion from all other effusions was 0.93. In the immunohistochemical analysis of M30, all pathologic types of cancer cells showed moderate to high expression, and the epithelioid cells in granulomas showed high expression in tuberculous pleural tissues. CONCLUSION: Caspase-cleaved cytokeratin 18 was most prominently observed in tuberculous pleural effusion and showed utility as a clinical marker. The main source of M30 was found to be the epithelioid cells of granulomas in tuberculous pleural tissues.

A 33-year-old-woman with twin pregnancy underwent genetic amniocentesis in our hospital at 16 weeks of gestation. Fetal chromosomal analysis showed 46,XY,inv(9) and 47,XX,+21. The affected twin was terminated by ultrasonographically guided intracardiac injection of 3 ml potassium chloride solution at 19 weeks of gestation. A healthy 2570 g male infant was born by cesarean section with Apgar scores of 8 and 9 at one and five minutes, respectively.

PURPOSE: Isolated noncompaction of the ventricular myocardium(INVM) can present as heart failure or arrhythmias in a child. It is a rare disorder, characterized by prominent trabecular meshwork and deep intertrabecular recesses. We still know little about the diagnosis, symptoms, and clinical outcomes of INVM. METHODS: We included in our study 6 patients who showed ventricular noncompaction on echocardiography. Patients were diagnosed as INVM were excessively prominent trabeculations with deep intertrabecular recesses were found on echocardiography. Patients who had other complex heart lesions such as pulmonary atresia with intact ventricular septum in addition to ventricular noncompaction, were excluded. RESULTS: Age at presentation ranged from 1 day 7 years, with follow up being as long as 6 years. Symptoms at initial presentation were heart murmur, paroxysmal supraventricular tachycardia, cyanosis, feeding intolerance, ventricular tachycardia, and cardiomegaly at fetal screening. Prominent trabeculations and intertrabecular recesses were observed at left ventricular apex in all six patients. All patients were alive at last follow-up. One patient showed WPW syndrome on electrocardiography. Echocardiography revealed decreased systolic function in 4 patients, and decreased systolic and diastolic function in 1 patient. One patient is currently asymptomatic. CONCLUSION: Six patients were diagnosed with INVM with various symptoms at initial presentation. Echocardiography is the most important tool in the diagnosis of INVM due to its morphological characteristics. INVM can rarely be the cause of long term systolic dysfunction, and early detection by echocardiographic screening may be beneficial.
