Abstract: Biliobiliary fistula is a rare clinical entity. The case of a 72 year old female, who presented with epigastric pain and jaundice, is detailed herein. Endoscopic retrograde cholangiopancreatography (ERCP) revealed two stones, one each in the common bile duct and the gallbladder. Continuous endoscopic nasobiliary drainage (ENBD) was performed to relieve obstructive jaundice. Further study with contrast medium administered via the ENBD tube revealed a fistula between the neck of the gallbladder and the common bile duct. The cystic duct was intact. A stone was considered to have migrated into the common bile duct through the fistula. A diagnosis of biliobiliary fistula, Corlette type I was made. However, in this particular case, a biliobiliary fistula was noted at a site below the junction of the cystic duct and common bile duct. Removal of the gallbladder stones was followed by cholecystectomy. The common bile duct was then repaired by utilizing a T-tube. No evidence of malignancy was recognized in the resected gallbladder specimen. In the one year to date since surgery, the patient has been asymptomatic and without signs of biliary disease. 相似文献

An ultrastructural study of the colonic mucosa was performed in four patients with antibiotic-associated haemorrhagic colitis and new findings are reported. Colonoscopy was performed and biopsy specimens were obtained within 24 h of the onset of bloody diarrhoea. Colonoscopy demonstrated diffuse oedematous and haemorrhagic mucosa with erosions and white coat. Light microscopy revealed mucosal haemorrhage and inflammatory cell infiltration. Ultrastructurally, platelet aggregation was frequently present in the lumina of colonic mucosal capillaries, causing engorgement of red blood cells in adjacent microvessels. Mild to severe damage was observed in capillary endothelial cells, including discontinuity of basement membranes, gaps between endothelial cells and the destruction of capillaries. There was no evidence of microvascular spasm. In conclusion, our findings suggest that antibiotics directly or indirectly cause microcirculatory disturbances, which result in tissue damage and haemorrhage, in the colonic mucosa. 相似文献

Primary carcirioma of the scalp seems to be a rare conditiont
as we failed to find any collective study of such cases in the English
literature. According to Hu and Chin (1), in the western countries,
basal cell carcinoma is much more common than squamous cell
carcinoma, but in China it is less frequent. Furtbermore, this affec-
tion presents peculiar features in its course and treatment which are
quite different from cancers of other internal or external organs of
the body. For these reasons, we feel that an analysis of the 35 cases
seen in the Peiping Union Medical College Hospital, in a period of
twenty years, may be reported. In each instance, except three, the
diagnosis was established by histopathological examination of the
tumor tissue; these cases were admitted to the Surgical and Tumor
Services. The three exceptions were patients who entered the hospital
for conditions other than the tumor itself, and the diagnosis was
based upon general physical examination. 相似文献

AIM: We evaluated a prostate biopsy strategy for cancer detection using a computer simulation system with virtual needle biopsy for three-dimensional (3D) prostate models. METHODS: Two 3D prostate models with a volume of 25 cc or 50 cc were constructed from computed tomographic images of radical prostatectomy specimens. The peripheral zone (PZ) and transition zone (TZ) were arranged in the prostate models according to the anatomical information. Four thousand patterns of cancer lesions were automatically inserted into each prostate model with a proportion of 75% in PZ and 25% in TZ. Average hit rates (AHR) in prostate models were evaluated both with an increased number of biopsy cores and various angles of virtual needle biopsy. The influence of adding secondary tumors for hit rates was also evaluated. RESULTS: For both sizes, the laterally angled biopsy in 4-8 core biopsy schemes showed higher AHR than the vertical plane biopsy, while the vertical plane biopsy in 10-18 core biopsy schemes showed higher AHR than the laterally angled biopsy. A higher number of biopsy cores increased the AHR of secondary tumors. CONCLUSIONS: Our results suggest that it is important in prostate cancer detection to change the needle placement according to the number of biopsy cores and the size of the prostate. 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: Thrombocytosis has been reported in many types of malignancies and has been studied as a prognostic factor. In the present study, we examined the incidence of thrombocytosis in patients with renal cell carcinoma (RCC) in order to evaluate the prognostic value of thrombocytosis. Methods: One hundred and ninety‐six patients treated by radical nephrectomy for RCC were enrolled in this study. We divided the patients into a normal platelet count group and a thrombocytosis group according to the presurgical platelet count. The two groups were compared pathologically and clinically, including prognosis. Results: Thrombocytosis was present in 16 patients (8.2%). Platelet counts had normalized after nephrectomy in all patients with thrombocytosis. There was no correlation between histological type or grade and thrombocytosis. However, there were correlations between thrombocytosis and tumor size and tumor stage. Patients with thrombocytosis had a worse prognosis than patients without thrombocytosis (P = 0.0028). When adjusted for stage or tumor size, the correlation was limited to low stage (stage 1 + 2: P = 0.0041, stage 3 + 4: P = 0.2983) or small tumors (tumor size: ≤4 cm, P = 0.0021; 4–7 cm, P = 0.0142; >7 cm, P = 0.8158). Conclusion: Thrombocytosis is an inexpensive and easy tool with which to evaluate the prognosis of RCC patients in daily medical practice. 相似文献

Background: The present paper describes a patient with a right temporal lobe variant (RTLV) of frontotemporal lobar degeneration (FTLD). Methods: The study was undertaken when the patient was completely independent in her environment and had not complained of any cognitive problems. Results: Under general neuropsychological assessment, the patient showed no notable deficit other than a difficulty in recognizing famous people by looking at photographs of their faces. Subsequent in‐depth evaluation indicated prosopagnosia: the patient presented with an impaired ability to recognize the faces of famous people and family members, whereas her visuospatial abilities were intact. Because the patient was able to recognize familiar people by their voices, the impairment was not a general loss of knowledge about people, but an inability to access this knowledge from visual stimuli (i.e. via the visual modality). The patient also exhibited a ‘within‐category’ learning deficit; however, her ability to learn from ‘across‐category’ visual stimuli remained intact. Conclusions: Overall, the results of the present study support the proposed model of RTLV of FTLD, where the first sign would be the disruption of face recognition components, leading to a selective form of associative prosopagnosia. Further, the co‐occurrence of face and ‘within‐category’ object learning deficits favor an interpretation in which a more generalized deficit occurs ‘earlier’ in the sequence of events associated with the object recognition process. 相似文献

Abstract Albumin immunoreactivity in the liver was examined on days 2, 5 and 10 after two-thirds partial hepatectomy by light and ultrastructural immunoperoxidase methods and the ultrastructural area of the rough endoplasmic reticulum (ER) in hepatocytes was measured. Albumin immunoreactivity was seen in the rough ER and Golgi apparatus of all hepatocytes in the hepatectomized liver and ultrastructural analysis showed a significantly greater area of rough ER on day 5 than on days 2 or 10. Albumin mRNA was studied by the in situ hybridization technique using radioisotopes and their numbers were determined visually. Albumin mRNA was present as grains in all hepatocytes and the grains varied in number during regeneration of the liver, being more abundant on day 5 than on days 2 or 10. The activity of [3 H]-leucine incorporated into albumin synthesis, an indicator of translational activity, was higher on days 5 and 10 than on day 2 and was highest on day 5. In conclusion, albumin synthesis varied during liver regeneration after partial hepatectomy, being reduced at the peak of cell proliferation on day 2 and being most active on day 5. 相似文献
