Purpose To describe three cases of mirror foot and to develop a new classification of the mirror feet with an emphasis on their treatment.
Methods Surgical treatment was performed on three patients with mirror foot. Mirror feet in the English literature were surveyed and
cases found in PubMed as well as our three cases were classified according to a new classification that was an analogy of
the mirror hand classification proposed by Al-Qattan et al. (J Hand Surg Br 23:534–536, 1998).
Results All three cases obtained satisfactory outcome after the treatment. In addition to these cases, 28 mirror feet were well described
in the English literature, among which only seven cases have been documented for their treatment. All of the cases could be
assigned to one of the categories of the proposed classification.
Conclusion Mirror foot is a very rare congenital deformity of the foot. We successfully treated three novel cases of mirror feet. A classification
of the mirror feet proposed in this article was useful in order to understand its nature and obtain a guideline for its treatment. 相似文献

Development of early apoptosis and changes in lymphocyte subsets were examined in lymphoid organs of female BALB/c mice after oral administration of 15 mg/kg b.w. of nivalenol (NIV), the major type B trichothecene mycotoxin, by FACS analysis. Judging from the results of viable cell count and apoptotic cell index, NIV attacked Peyer's patches first and thymus most severely. In thymus, selective damage in CD4(+)CD8(+) cells was observed at 12 and 24 h after inoculation (HAI), following the peak of apoptosis at 9 HAI. CD4(+) cells were clearly suppressed at 3 HAI in Peyer's patches, at and after 9 HAI in mesenteric lymph nodes, and 3 to 12 HAI in spleen, respectively. CD8(+) cells were also suppressed at 24 HAI in mesenteric lymph nodes and at 12 HAI in spleen, respectively. As to changes in B cell subsets, IgG(+) cells significantly decreased from 3 to 12 HAI and all B cell subsets at 24 HAI in mesenteric lymph nodes. In spleen, IgM(+) cells were suppressed at 9 HAI. On the other hand, in Peyer's patches, following clear decrease in the numbers of pan-T and pan-B cells and viable cells at 3 HAI, all B cell subsets, especially IgA(+) cells, showed a significant increase in their numbers at 9 HAI, and the numbers of IgA(+) and IgM(+) cells remained higher values than controls thereafter. Taken together, in the course of recovery from NIV-induced prominent damage in Peyer's patches at 3 HAI, interaction of NIV with Peyer's patches might result in in vivo stimulation of interleukin production at this site and result in increased proliferation and differentiation of IgA-secreting B cells at and after 9 HAI. 相似文献

No strategies for the diagnosis and treatment of biliary tract carcinoma have been clearly described. We developed flowcharts for the diagnosis and treatment of biliary tract carcinoma on the basis of the best clinical evidence. Risk factors for bile duct carcinoma are a dilated type of pancreaticobiliary maljunction (PBM) and primary sclerosing cholangitis. A nondilated type of PBM is a risk factor for gallbladder carcinoma. Symptoms that may indicate biliary tract carcinoma are jaundice and pain in the upper right area of the abdomen. The first step of diagnosis is to carry out blood biochemistry tests and ultrasonography (US) of the abdomen. The second step of diagnosis is to find the local extension of the carcinoma by means of computed tomography (CT), magnetic resonance imaging (MRI), magnetic resonance cholangiopancreatography (MRCP), percutaneous transhepatic cholangiography (PTC), and endoscopic retrograde cholangiopancreatography (ERCP). Because resection is the only way to completely cure biliary tract carcinoma, the indications for resection are determined first. In patients with resectable disease, the indications for biliary drainage or portal vein embolization (PVE) are checked. In those with nonresectable disease, biliary stenting, chemotherapy, radiotherapy, and/or best supportive care is selected. 相似文献

Tissue accumulation of advanced glycation end products (AGE) is thought to contribute to the progression of cardiovascular disease (CVD). Skin autofluorescence, a non‐invasive measure of AGE accumulation using autofluorescence of the skin under ultraviolet light, has been reported to be an independent predictor of mortality associated with CVD in Caucasian patients on chronic hemodialysis. The aim of this study was to assess the predictive value of skin autofluorescence on all‐cause and cardiovascular mortality in non‐Caucasian (Japanese) patients on chronic hemodialysis. Baseline skin autofluorescence was measured with an autofluorescence reader in 128 non‐Caucasian (Japanese) patients on chronic hemodialysis. All‐cause and cardiovascular mortality was monitored prospectively during a period of 6 years. During the follow‐up period, 42 of the 128 patients died; 19 of those patients died of CVD. Skin autofluorescence did not have a significant effect on all‐cause mortality. However, age, carotid artery intima‐media thickness (IMT), serum albumin, high‐sensitivity C‐reactive protein (hsCRP), skin autofluorescence and pre‐existing CVD were significantly correlated with cardiovascular mortality. Multivariate Cox regression analysis showed skin autofluorescence (adjusted hazard ratio [HR] 3.97; 95% confidence interval [CI]1.67–9.43), serum albumin (adjusted HR 0.05; 95% CI 0.01–0.32), and hsCRP (adjusted HR 1.55; 95% CI 1.18–2.05) to be independent predictors of cardiovascular mortality. The present study suggests that skin autofluorescence is an independent predictor of cardiovascular mortality in non‐Caucasian (Japanese) patients on chronic hemodialysis. 相似文献

Collective cell migration, in which cells assemble and move together, is an essential process in embryonic development, wound healing and cancer metastasis. Chemokine signaling guides cell assemblies to their destinations. In zebrafish posterior lateral line primordium (PLLP), a model system for collective cell migration, it has been proposed that the chemokine ligand Cxcl12a secreted from muscle pioneer cells (MPs) and muscle fast fibers (MFFs), which are distributed along with the horizontal midline, binds to the receptor Cxcr4b in PLLP and that Cxcl12a–Cxcr4b signaling guides the anterior‐to‐posterior migration of PLLP along the horizontal midline. However, how the surrounding tissues affect PLLP migration remains to be elucidated. Here, we investigated the relationship between the PLLP and the surrounding tissues and found that a furrow between the dorsal and ventral myotomes is generated by Sonic hedgehog (Shh) signaling‐dependent MP and MFF differentiation and that the PLLP migrates in this furrow. When transient inhibition of Shh signaling impaired both the furrow formation and differentiation of cxcl12a‐expressing MPs/MFFs, directional PLLP migration was severely perturbed. Furthermore, when differentiated MPs and MFFs were ablated by femtosecond laser irradiations, the furrow remained and PLLP migration was relatively unaffected. These results suggest that the furrow formation between the dorsal and ventral myotomes is associated with the migratory behavior of PLLP. 相似文献

A duodenum-preserving pancreatic head resection technique was first reported in 1980, but the indications have been limited
to benign pancreatic disease as it involves a subtotal pancreatic head resection. In 1988 we detailed a duodenum-preserving
total pancreatic head resection (DPTPHR) technique. This procedure involved a total pancreatic head resection and as such
expanded the indications for this approach to include tumorigenic masses. The original method involved closure of the proximal
pancreatic duct and an anastomosis of the pancreatic duct of the distal pancreas to a newly created small hole in the duodenum
(we termed this a "pancreatoduodenostomy"). Our current technique involves a duct-to-duct anastomosis of the proximal pancreatic
duct and the distal pancreas to better preserve anatomic structure. DPTPHR was performed in 26 patients from 1988 to 2002,
including 12 cases of DPTPHR with pancreatoduodenostomy and 14 cases of DPTPHR with pancreatic duct-to-duct anastomosis. No
differences were observed between the two methods with respect to operative time or blood loss during surgery. Postoperatively,
there was one case of cholecystitis and one case of pancreatitis in a patient who underwent a pancreatoduodenostomy; both
of these patients were treated conservatively with curative intent. No complications were observed in the group undergoing
duct-to-duct anastomosis. The advantage of duct-to-duct anastomosis is that the pancreatic head is totally resected, thus
allowing removal of neoplastic disease such as an intraductal papillary mucinous tumor and also therapy for chronic pancreatitis.
A key benefit of this procedure is that sphincter function of the duodenal papilla is preserved permitting drainage of pancreatic/bile
juice into the duodenum, preserving a more physiologic state than is the case after a pancreatoduodenostomy.

In order to establish human monoclonal antibodies to any sort of antigens efficiently, we have made following two approaches. Our first approach is to improve cell fusion frequency. By improving our previous method for production of human hybridomas, we obtained higher frequency (1/700 vs. 1/5500) compared with our previous method by adding irradiated myeloma cells to culture of fusion cells and modifying the selective medium. Our second approach is to use a SCID-hu mouse for immunization. Since the injection of human PBL can result in the stable long-term reconstitution of a human immune system in SCID mouse, we tried to immune SCID-hu mouse with KLH. In the serum of immunized SCID-hu mouse, we obtained human IgG antibodies to KLH. Additionally, we succeeded in establishing human B lymphoblastoid cell lines which produced antibodies specific to KLH. These methods will open new prospects for the detection and therapy of cancer. 相似文献
