Coexistence of renal replacement lipomatosis with xanthogranulomatous pyelonephritis 总被引:1,自引:0,他引:1

We report on a case of coexistence of replacement lipomatosis with xanthogranulomatous pyelonephritis (XGP) in the same kidney associated with staghorn calculi. A 63-year-old man was admitted to hospital complaining of a right abdominal mass. Computed tomography (CT) showed renal parenchymal atrophy with extremely increased perirenal fat. Right nephrectomy was performed. Postoperative diagnosis was renal replacement lipomatosis with XGP. Renal replacement lipomatosis and XGP have several similarities in terms of clinical background and CT findings. Sometimes it is difficult to differentiate them from malignant diseases. It is extremely rare that both conditions coexist in the same kidney. To our knowledge, only one such case has been reported. 相似文献

Summary: Transforming growth factor-α (TGF-α) and epidermal growth factor (EGF) are structurally related mitogenic polypeptides. They share the same receptor; EGF receptor. the EGF receptor is widely expressed in human fetal tissues including the kidney, but little is known about the role of TGF-α/EGF/EGF receptor system in human fetal kidney. the expression of TGF-α, EGF and their common receptor was investigated immunohistochemically in the human fetal kidneys. In the cortex, immunoreactivity for TGF-α was found in the differentiating proximal tubules. In contrast, immunoreactivity for EGF was present in the thick ascending limbs of the Henle's loop (TAL) and medullary collecting duct cells (CD). Immunoreactivity for their common receptor was present mainly in the TAL and medullary CD. These data support the assumption that the system of TGF-α, EGF and its receptor has an important role in the proliferation and differentiation of the TAL and medullary CD. the different localization of TGF-α and its receptor may indicate that TGF-α acts through a paracrine mechanism. the co-localization of EGF and its receptor in the TAL and medullary CD suggests that EGF may act as an autocrine growth factor. 相似文献

BACKGROUND: Local force distribution supporting the bodyweight of infants with Down syndrome (DS) appears to be different from that of healthy controls. The purpose of the present study was to establish methods to assess this force distribution and to allow therapeutic evaluation of neurological development in DS infants prior to walking. METHODS: Contact pressure distribution patterns in supine and prone positions were measured by photoelastic methods and were compared between DS infants and healthy controls. The DS group included eight subjects, seven with regular trisomy 21, and one with a Robertson translocation. The controls consisted of 14 neonates, four 4-month-old infants and eight 7-month-old infants. RESULTS: In both groups, head loading ratio decreased as age advanced but the decrement was less in the test group than in the control group. When the bodyweight loading ratios were measured in two different lying positions, that is, prone and supine, the ratios for prone generally tended to be smaller than those for supine in the controls. This kind of difference between prone and supine was not seen in the DS group. The bodyweight is somewhat sustained with limbs and the limbs loading ratios in the DS group were always significantly lower than in the controls. CONCLUSION: Coordinated development of weight-supporting limbs seems to be poor in the DS group. 相似文献

The aim of the present study was to clarify whether bile acids influence chemiluminescence (CL) in the liver in vivo. Hepatic CL was determined on the surface of the liver of anaesthetized rats by using a photon counter. In normal rats, hepatic CL was significantly decreased 30 min after enteral administration of chenodeoxycholic acid (CDCA) or deoxycholic acid (DCA), but returned to its initial level 3 h later, after part of the CDCA administered was metabolized. Ursodeoxycholic acid (UDCA) and cholic acid had no effect on CL. In contrast, hepatic CL was markedly increased 30 min after CDCA or DCA administration in rats given either buthionine sulphoximine (BSO), an inhibitor of γ-glutamylcysteine synthetase, or diethyldithiocarbamate (DDC), an inhibitor of both superoxide dismutase and glutathione peroxidase. Chenodeoxycholic acid further increased the CL of BSO- or DDC-treated rats during inhalation of oxygen via a tracheal cannula. Coadministration of UDCA eliminated the effects of CDCA on the hepatic CL of normal and BSO- or DDC-treated rats with or without oxygen inhalation. We conclude that cytotoxic bile acids, such as CDCA, increase CL in the antioxidants-depleted or oxidative-stressed liver in vivc, but that UDCA prevents CDCA from developing CL. 相似文献

Background. The microvasculature plays an important role in the pathogenesis of psoriatic skin lesions. Our purpose was to try to define a psoriatic pattern in the nailfold capillary, to clarify the relationship between nailfold capillary microscopic changes and nail involvement and to note the general clinical features of psoriasis. Methods. Image analysis of nailfold capillaries was performed in 62 patients with psoriasis. The capillary pattern was defined statistically comparing it with that of 51 healthy volunteers. We attempted to differentiate the psoriatic pattern from normal controls with “canonical discriminant analysis.” Results. Forty-nine of 62 patients with psoriasis could be differentiated from normal controls by our definition of psoriatic pattern that was significantly correlated with periungual psoriatic plaque, nail pitting, onycholysis, and the extent of the involved area. Conclusions. Our data suggest that nailfold capillary changes reflect microvascular changes of psoriasis and that the nailfold capillary pattern is a useful tool in evaluating nail involvement and the severity of psoriasis. 相似文献

We describe the present view of performing diagnostic endoscopic ultrasonography guided fine needle aspiration biopsy (EUS‐FNAB). In the pancreatic diseases, our application of EUS‐FNAB for pancreatic disease has been as follows: as to the operable cases, EUS‐FNAB should not be performed through any pathway penetrating the duodenum and the stomach. EUS‐FNAB is contraindicated in cystic diseases. As to the cases diagnosed as inoperable with various imaging modalities, EUS‐FNAB should be performed to obtain the pathological evidence. In gastrointestinal disorders, all intramural diseases are appropriate indications for this procedure. Even if the target lesion is in the far oral part of the large intestine, we perform EUS‐FNAB by the special method described in this paper. Lymphadenopathy for appropriate cases is one of the best cases in which to perform EUS‐FNAB. Mediastinal lymph node metastasis influences the treatment plan of lung cancer; the application of this treatment is increasing in our institute. 相似文献

ABSTRACT. Okada, S., Seino, V., Kodama, H., Yutaka, T., Inui, K., Ishida, M., Yabuuchi, H. and Seino, Y. (Department of Pediatrics, Osaka University Hospital, Fukushima-ku, Osaka and The Third Division, Department of Medicine, University of Kobe, Kobe, Japan). Insulin and glucagon secretion in hepatic glycogenoses. Acta Paediatr Scand 68: 735, 1979.—Insulin and glucagon secretion was investigated in ten patients with hepatic glycogenosis, types I and III, in order to understand the relationship between hypoglycemia and pancreatic function. In all patients, both oral glucose tolerance and intravenous arginine infusion tests revealed hypoinsulinemia. Decreased urinary C-peptide levels with standard food intake also supported hypofunction of pancreatic beta cells. On the contrary, the normal secretion pattern of glucagon in both types indicated in the arginine loading test, intact alpha cells in the pancreas. Persistent hypoinsulinism, which is apparently an adaptation to hypoglycemia, could be an important cause of nutritional dwarfism in both types of glycogenosis. The usefulness of the measurement of urinary C-peptide, which evaluates the pancreatic function and provides management for normal body growth, is discussed. 相似文献
