We reviewed 109 consecutive patients with cancer of the hypopharynx or cervical oesophagus who underwent free flap transfer for immediate reconstruction after total pharyngolaryngo-oesophag-ectomy. The free flaps used were either free jejunal (n = 70) or radial forearm flaps (n = 39). Significantly more fistulas (3/70 compared with 15/39, p < 0.0001) and strictures (6/64 compared with 13/33, p = 0.0008) developed in the radial forearm than the jejunal flap group. However, functional donor site morbidity was minimal and there were no cases of total flap necrosis in the forearm flap group. We consider that the free jejunal flap should be the first choice for total reconstruction of pharyngo-oesophageal defects. However, the forearm flap is suitable for elderly, high risk patients, because it is less invasive and has minimal donor site morbidity, which facilitates early recovery. 相似文献

Gender differences in maximum voluntary lip-closing force during lip pursing in healthy young adults
Murakami M Adachi T Nakatsuka K Kato T Oishi M Masuda Y 《Journal of oral rehabilitation》2012,39(6):399-404
The objectives of this study were to quantitatively evaluate the gender differences in the lip-closing force (LCF) generated during pursing-like lip-closing movement using a multidirectional LCF measurement system in healthy young adults. In 40 healthy subjects (20 women, 20 men; median age = 26·5 years, range = 22-41 years), LCF was recorded in eight directions during the performance of a voluntary pursing-like lip-closing task in four measurement sessions. The correlations between the total sum of the forces generated in all eight directions [total LCF (TLCF)] and each directional LCF (DLCF) and those between opposing DLCF were statistically analysed. The TLCF obtained from the highly reproducible measurements acquired in the four different sessions was normally distributed in both genders. The TLCF in men was significantly greater than that in women. Among the eight pairs of opposing DLCF, seven pairs of opposing DLCF showed significant correlations in men, while five pairs were significantly correlated in women. In men, no significant difference was observed between opposing DLCF; however, three pairs of opposing DLCF were significantly different in women. The present results quantitatively indicate that there are gender differences in the magnitude and directional specificity of the LCF produced during pursing-like lip-closing movement in healthy young adults. 相似文献

Conclusion The present findings show that all four types of histamine receptors (H1R, H2R, H3R, and H4R) are present in the inner ear, thus supporting the hypothesis that histamine plays a physiological role in the inner ear. Objective To analyse the presence of histamine receptors in the normal mouse inner ear. Methods CBA/J mice were used in this study. The localization of H1R, H2R, H3R, and H4R in the inner ear, i.e. cochlea, vestibular end organs, vestibular ganglion, and endolymphatic sac, was studied by real-time PCR and immunohistochemistry. Results The mRNA for each receptor sub-type was detected in the inner ear. In the immunohistochemical study, the organ of Corti, spiral ganglion, vestibular ganglion, vestibular sensory epithelium, and endolymphatic sac cells showed an immunofluorescent reaction to all histamine receptors. 相似文献

Inflammation-based markers predict the long-term outcomes of various malignancies. We investigated the relationship between the modified Glasgow prognostic score (mGPS) and the long-term outcomes of obstructive colorectal cancer in patients who underwent self-expandable metallic colonic stent placement and subsequently received curative surgery. We retrospectively analyzed 63 consecutive patients with pathological stage II and III obstructive colorectal cancer from 2013 to 2018. The mGPS was calculated before stenting and surgery, and the difference of the scores was defined as the d-mGPS. All d-mGPS = 2 patients were > 70 years of age (p = 0.01). Postoperative complications were more common in the preoperative mGPS = 2 group (p = 0.02). The postoperative hospital stay was significantly longer in the mGPS = 2 group (p = 0.007). Multivariate analyses revealed that d-mGPS was an independent prognostic factor for overall survival (OS) (hazard ratio [HR] = 9.18, p = 0.004) and cancer-specific survival (HR = 9.98, p = 0.01). Preoperative mGPS = 2 was significantly associated with poor OS (HR = 5.53, p = 0.04). The results indicated that mGPS might serve as a valuable indicator of the immunonutritional status of preoperative patients, and a preoperative change of the status might affect the long-term outcomes of patients with obstructive colorectal cancer. 相似文献

Purpose
The aim of this study was to detect high-performance prognostic biomarkers of pancreatic cancer which would enable the identification of high-risk patients.Methods
The subjects were 324 patients who underwent radical surgery for pancreatic ductal adenocarcinoma without neoadjuvant therapy. We evaluated the prognostic impact of four perioperative serum tumor markers, including carbohydrate antigen 19-9 (CA19-9) and carcinoembryonic antigen (CEA). We also evaluated the indices by multiplying the values of two tumor markers (e.g., CA19-9 × CEA).Results
The preoperative CA19-9 × CEA index had a strong correlation with the prognosis of patients with pancreatic cancer, even when the cut-off was set at the median value. CA19-9 × CEA ≥500 was an independent predictor of mortality (hazard ratio: 1.642, p = 0.021). In the ROC curve analysis of early mortality after surgery, the CA19-9 × CEA index had the highest goodness of fit. The presence of CA19-9 × CEA ≥500 had the largest attributable risk proportion because of its combined high predictive performance and prevalence. The postoperative CA19-9 × CEA index was also a significant predictive marker of mortality.Conclusion
The CA19-9 × CEA index is a strong prognostic biomarker that could help identify pancreatic cancer patients expected to have a poor prognosis so that they can be administered appropriate multidisciplinary treatment. 相似文献89.

Clostridium perfringens beta-toxin is a key mediator of necrotizing enterocolitis and enterotoxemia. It is a pore-forming toxin (PFT) that exerts cytotoxic effect. Experimental investigation using piglet and rabbit intestinal loop models and a mouse infection model apparently showed that beta-toxin is the important pathogenic factor of the organisms. The toxin caused the swelling and disruption of HL-60 cells and formed a functional pore in the lipid raft microdomains of sensitive cells. These findings represent significant progress in the characterization of the toxin with knowledge on its biological features, mechanism of action and structure-function having been accumulated. Our aims here are to review the current progresses in our comprehension of the virulence of C. perfringens type C and the character, biological feature and structure-function of beta-toxin. 相似文献
