To determine the extent of progress in the treatment of sacrococcygeal teratomas (SCTs), we evaluated the experience with 73 patients over 40 years. The medical records of the children were reviewed for demographics, histology, clinical course, and outcome. Therapy differed depending on the type of SCT, histology, and decade of diagnosis. The female:male ratio was 4.2:1 and did not vary significantly with the histology of the tumor. Fifty-seven patients presented with benign disease. There were five recurrences in this group, only one of which did not have an initial coccygectomy. One tumor, originally thought to be benign with immature elements, had a local recurrence at 7 months, 10 months, and 16 months after the original operation and was discovered to have embryonal carcinoma with nodal involvement. This child was treated with chemotherapy and is disease-free at 7 years. Morbidity in the benign group included 3 postoperative wound infections. Three infants died, one before operation with beta-hemolytic Streptococcus sepsis. Two neonates died in the early postoperative period, one on day 1 with a ruptured subcapsular hematoma of the liver, and the second on day 2 with disseminated intravascular coagulation/sepsis. Benign SCT occurs at a younger age than malignant tumors. The average age of presentation of benign tumors is 20 days versus 468 days in children with malignant disease. The technique of wide resection of benign lesions with coccygectomy is helpful in preventing recurrence and has changed little over the last four decades. Malignant SCT occurred in 16 children (22%).(ABSTRACT TRUNCATED AT 250 WORDS)

Hemobilia is relatively rare among hemorrhages in the digestive tract, and hemobilia caused by tumors of the biliary tract is particularly rare. We treated a 74-year-old-man with undifferentiated carcinoma of the gallbladder presenting with hemobilia. During hospitalization for neurogenic bladder at the Department of Urology, he showed progressive anemia. Since hemorrhage in the digestive tract was suspected, endoscopy of the upper gastrointestinal tract was performed, and bleeding from the papilla of Vater was observed. On ultrasound examination, findings were indicative of cholecystic cancer, and hemorrhage from the cystic duct was found on percutaneous transhepatic cholangioscopy. On perioral cholecystoscopy, however, masses of coagulated blood were found only in the gallbladder. Abnormalities such as dense staining of tumors or extravasation were not found on angiography. The patient died of hepatic failure due to rapid invasion of the liver by the tumor, associated with biliary infection and disseminated intravascular coagulation. At autopsy, a nodal tumor was found in the gallbladder, and the cavity of the gallbladder was filled with coagulated masses of blood. Direct invasion of the tumor to the liver, diaphragm, and transverse colon was found. The histopathological diagnosis was undifferentiated carcinoma (pleomorphic large-cell type).

Hyperplastic mesothelial cells involving lymph node sinuses have only been recently described. Most nodal mesothelial cells are thought to originate from mesothelial surfaces disrupted by serosal effusions. Dislodged mesothelial cells likely gain access to submesothelial lymphatics via mesothelial stomata and disseminate to draining lymph nodes. Unusual lymph node architectural patterns result when benign sinus mesothelial cells occur concurrently with a neoplastic nodal process. We describe a young man who developed diffuse metastases from a primary cardiac angiosarcoma. His periaortic lymph nodes contained metastatic angiosarcoma and hyperplastic mesothelial cells with a sinus distribution. The patient had a clinical history of progressive haemoperitoneum, exacerbated by thrombocytopaenia and disseminated intravascular coagulation. Massive haemoperitoneum of 5000 ml was confirmed at autopsy. This is the first report to suggest that multiple episodes of intraperitoneal haemorrhage and ascites may both act in the same manner to cause dislodgment and dissemination of mesothelial cells to draining lymph node sinuses.

We studied 11 cases of nodal cytotoxic T-cell lymphoma, which express the CD8+ phenotype and cytotoxic molecules (T-cell intracellular antigen-1, granzyme B and perforin), to characterize the clinicopathologic spectrum of these neoplasms. The 11 cases consisted of four men and seven women, aged 5 to 82 years (mean, 53 years). All cases were nodal, and eight of 11 had extranodal involvement, the most common being in bone marrow (eight cases) and liver (six cases). The expression of these cytotoxic molecules has been reported in some T/natural killer cell lymphomas mostly involved in extranodal sites of skin, nasopharyngeal region, or gastrointestinal tracts, but these types of extranodal involvement were rare in our cases. Morphologically these lymphomas could be divided into two groups. One group (n = 6) showed a diffuse large cell type and massive necrosis or apoptosis that was accompanied by disseminated intravascular coagulation (DIC) or hemophagocytic syndrome (HPS) on the initial. The prognosis of this group was generally poor (survival = 1-19 months, median = 5 mo), and four of these six cases were fulminant. The other group (n = 5) showed a diffuse medium or mixed cell type, and the prognosis was not so poor (median survival = 17 mo). Our results suggest that these nodal cytotoxic T-cell lymphomas originated from activated cytotoxic T-cells and were highly accompanied with DIC or HPS.

A 75-year-old man was admitted to our hospital complaining of gastric fatigue. Endoscope and CT scan revealed type 3 gastric cancer with paraaortic lymph nodal metastasis. Histological examination of the endoscopic biopsy revealed poorly differentiated adenocarcinoma. A blood examination and bone marrow biopsy revealed DIC causing bone marrow carcinosis. Chemotherapy with sequential therapy consisting of MTX and 5-FU was performed. Stretch of the fold and flatness of the ulcer were obtained against the gastric primary lesion observed endoscopically. Complete response was obtained against the lymph node around the abdominal aorta. Reduction of low back pain and DIC were observed. He was thus able to be discharged and sequential therapy was performed again over 2 months in outpatient care.

A 36-year-old man was diagnosed with plasma-cell type Castleman's disease with the presentation of recurrent lymphadenpathy of the neck. HIV infection was not suspected or confirmed until esophageal candidiasis developed one year later. Meanwhile, surgery was performed for intestinal intussusception and obstruction caused by lymphocyte-depletion Hodgkin lymphoma. However, he died of rapidly progressive pneumonia and disseminated intravascular coagulation associated with intracerebral hemorrhage, which occurred 6 months later during the course of chemotherapy. This case suggests that HIV infection should be considered in patients who present with plasma-cell type Castleman's disease or lymphocyte-depletion Hodgkin lymphoma with extra-nodal involvement in order to conduct appropriate diagnosis and initiate treatment for HIV infection.

The earliest left-right asymmetry in mouse development arises in 7.5 days, at the ventral surface of the embryonic node. The node cells possess monocilia beating in rotatory fashion to generate fluid flow from the right to the left (nodal flow). The direction of nodal flow will determine the side of expression of nodal, the responsible gene for "leftness." Nodal flow is visualized by combination of DIC (differential interference contrast) and microbeads in culture medium. Node cilia movement is visualized by DIC, a high-speed camera, and image processing.

Multilevel extended digital image correlation (X-DIC) technique based on finite element method (FEM) is applied for measuring deformation of geomaterials under uni-axial loading condition. The concept of Smooth Particle Hydrodynamics (SPH) is introduced for smoothing computed displacements as well as for calculating strain tensors at every nodal point of FEM mesh. Cumulative effective strain estimated from strain tensors is found to be a well suited parameter to identify the change in stress-strain behaviour in experimented samples. Further analysis suggests that onset of microcrack development and yielding in samples can also be identified using this parameter. Based on these findings, an indicator is developed for determining onset of both microcrack development and yielding in geomaterials. This indicator is found to be related to volumetric strains and may also signify dilation of the sample. The potential of the developed indicator is tested by conducting four experimental works with concrete and rock samples.
