Introduction
Pancreatic fistula (PF) after pancreaticoduodenectomy (PD) is still a serious complication. We hypothesized that the amount of fatty tissue in the pancreatic parenchyma could be associated with the occurrence of PF after PD with pancreatogastrostomy. 相似文献3.

Papillary fibroelastoma is a rare benign cardiac tumor with elevated risk for embolization. This report describes the case of a 65-year-old man, admitted for the occasional finding of a round, pedunculate mass adherent to the chordae of the anterior mitral valve leaflet, mimicking an endocarditic mass. Appropriate diagnostic evaluations lead to the suspect of a papillary fibroelastoma. Because of the elevated risk of thromboembolism, surgery was emergently performed with complete removal of the mass and preservation of the integrity of the mitral valve. Histologic evaluation confirmed the diagnosis. Papillary fibroelastoma should be always considered in the differential diagnosis of intracardiac masses. 相似文献

Internal quality control (IQC) is a necessary component of total quality management. We report our experience with an internal audit scheme focusing on the histological diagnosis. We outline other strategies of IQC and analyze the causes of errors and ways to prevent them. Some practical guidelines to initiate this type of procedure are presented. Our audit was designed to check the accuracy of diagnosis, the clarity and completeness of the report, the quality of the documents leading to the diagnosis, and the turn-around time. It consisted of a retrospective analysis of 4185 randomly selected cases (representing 2% of all cases), over nine years. The control took place once a week and was done by two pathologists working as a team. The mean time spent by each pathologist was 45 minutes per week. Errors were scored using a 3-level grading scheme depending on their potential harm or impact on patient care. The overall rate of errors was 1.1%, and 0.1% of errors were potentially harmful to the patients. A single case (0.02%), in which a cancer was missed, had a real impact on patient care. Retrospective analysis of randomly selected cases mirrors the overall activity of a surgical pathology department. Nevertheless, each lab has to develop its own strategy of IQC, based on its size, its functioning, and its objectives. Although it may be difficult to initiate quality assurance when medical time is already limited, it is a helpful procedure in a more and more demanding medical and societal context and a pragmatic step towards "culture of quality". 相似文献

OBJECTIVE: To investigate whether sinusoidal injury (SI) was associated with a worse outcome after hepatectomy in patients with colorectal liver metastases (CRLM). BACKGROUND: Correlation between SI and oxaliplatin-based chemotherapy (OBC) was recently shown in patients with CRLM. However, it has yet to be fully clarified whether SI affects liver functional reserve and outcome after hepatectomy. PATIENTS AND METHODS: Between 2003 and 2005, 90 patients with CRLM who underwent an elective hepatectomy after preoperative chemotherapies were included. Diagnosis of SI was established pathologically in the nontumoral liver parenchyma of the resected specimens, and perioperative data were assessed in these patients. RESULTS: OBC was significantly associated with a higher incidence of SI. Preoperative indocyanine green retention rate at 15 minutes (ICG-R15) and postoperative value of total-bilirubin were significantly higher, and hospital stay was significantly longer in patients presenting with SI. Multivariate analysis showed that female gender, administration of 6 cycles or more of OBC, abnormal value of preoperative aspartate aminotransferase >36 IU/L, or abnormal value of preoperative ICG-R15 (>10%) were preoperative factors significantly associated with SI. Among patients undergoing a major hepatectomy, SI was significantly associated with higher morbidity and longer hospital stay. CONCLUSION: The present study suggests that SI resulted in a poorer liver functional reserve and in a higher complication rate after major hepatectomy. Therefore, female patients who received 6 cycles or more of OBC, or presenting with abnormal preoperative aspartate aminotransferase and ICG-R15 values should be carefully selected before deciding to undertake a major hepatectomy. 相似文献

Background: Scanning electron microscopy (SEM) study of the human incus bone is scanty whilst, to our knowledge, no information regarding human incudo-malleolar joint articular-cartilage morphology has previously been provided.Aims/objectives: Our aim was to shed some light on this morphological issue and to propose some theoretical perspectives on its functional role.Material and methods: The human incudo-malleolar joint was documented with field emission SEM on samples recovered during ear surgery procedures after patients’ informed consent.Results: Normal articular cartilage chondrocytes, flattened cells with prominent nucleus and short microvilli were observed. Interestingly, cells provided with long cilia were identified. Type A cilia are arranged in a pyramidal formation with extra-long cilia stemming from the cluster, projecting upwards in an antenna-like formation ending with a dilated structure that as a whole, resembles the stereocilia with kinocilium. Types B, C and D cilia resemble those of the genital and respiratory tracts.Conclusions and significance: It is therefore possible to hypothesize that the observed ciliated cells may be a new chondrocyte phenotype with sensory function. Motile cilia confer the ability to distinguish variations in synovial fluid chemical composition and, in addition, they perhaps may also play some role in the mechanism of sound transmission. 相似文献

Purpose
The goal of this study was to evaluate the ultrastructure of cytoplasmic fragments along with the effect of cytoplasmic fragment and perivitelline space coarse granulation removal (cosmetic microsurgery) from embryos before embryo transfer on ART outcomes.Methods
One hundred and fifty intracytoplasmic sperm injection cycles with male factor infertility were included in this prospective study. Patients were divided into three groups of case (n?=?50), sham (n?=?50), and control (n?=?50). Embryos with 10–50 % fragmentation were included in this study. Cosmetic microsurgery and zona assisted hatching were only performed in case and sham groups respectively. Extracted fragments were evaluated ultrastructurally by transmission electron microscopy (TEM). Rates of clinical pregnancy, live birth, miscarriage, multiple pregnancies, and congenital anomaly in the three groups were also compared.Results
Micrographs from TEM showed that mitochondria were the most abundant structures found in the fragments along with mitochondria-vesicle complexes, Golgi apparatus, primary lysosomes, and vacuoles. There were no significant differences in demographic characteristics, laboratory and clinical data, or embryo morphological features between the groups. The rate of clinical pregnancy in control, sham, and case groups had no significant differences (24, 18, and 18 %, respectively). The rates of live birth, miscarriage, multiple pregnancy, and congenital anomaly were also similar between the different groups.Conclusions
Our data demonstrated that cosmetic microsurgery on preimplantation embryos had no beneficial effect on ART outcomes in unselected groups of patients. As mitochondria are the most abundant organelles found in cytoplasmic fragments, fragment removal should be performed with more caution in embryos with moderate fragmentation.9.

Application of nonspecific phosphodiesterases inhibitors, such as pentoxifylline (PTX), is a strategy utilised to aid sperm selection from immotile sperm samples prior to ICSI. No extensive studies have yet been performed to verify the safety of the clinical outcomes of ICSI after PTX administration. In this article, we summarise the data reported in the literature that assess the implication of in vitro usage of PTX on sperm parameters, as well as clinical outcomes during assisted male reproduction programme. 相似文献

Plasma loads of torque teno virus (TTV) among individuals differ extensively beginning early in life, suggesting a role for innate immunity. Here, congenital mannose-binding lectin deficiencies, but not deficiencies in respiratory ciliary function, correlated with increased TTV loads. Notably, however, the presence of either disorder was associated with particularly high TTV loads. 相似文献
