A sandwich graft was applied to the debrided cortical bone layer of the tibia in the case of a 72-year-old male patient with full-thickness necrotic burn injury. The combined graft consisted of a dermal template material and autologous split thickness skin graft. After application, the graft was found totally accepted and provided good functionality with acceptable appearance. Histopathologic evaluation revealed a complete take with revascularisation of the implant. Supporting lamellar bony trabecules were also seen in the deep dermal dermis representing a connection to the underlying bone. The use of the dermal matrix in deep burn exposing the bone provides a satisfactory functional result and good cosmetic appearance. 相似文献

Ganglioneuromas (GNs) are rare benign tumors and their association with neurofibromatosis type 1 (NF-1) is especially uncommon. We report in this article the case of a young woman, subjected to diagnostic work-up because of abdominal pain. Endoscopy and histology revealed not only a GN in the papilla of Vater, but also NF-1. Because of the size and macroscopic features of the lesion, we performed pancreatoduodenectomy, from which she recovered uneventfully. Histological examination of the resected tumor confirmed a diagnosis of GN. 相似文献

Chlamydiae are obligate intracellular bacteria that propagate in the inclusion, a specific niche inside the host cell. The standard method for counting chlamydiae is immunofluorescent staining and manual counting of chlamydial inclusions. High- or medium-throughput estimation of the reduction in chlamydial inclusions should be the basis of testing antichlamydial compounds and other drugs that positively or negatively influence chlamydial growth, yet low-throughput manual counting is the common approach. To overcome the time-consuming and subjective manual counting, we developed an automatic inclusion-counting system based on a commercially available DNA chip scanner. Fluorescently labeled inclusions are detected by the scanner, and the image is processed by ChlamyCount, a custom plug-in of the ImageJ software environment. ChlamyCount was able to measure the inclusion counts over a 1-log-unit dynamic range with a high correlation to the theoretical counts. ChlamyCount was capable of accurately determining the MICs of the novel antimicrobial compound and the already known antichlamydial antibiotics moxifloxacin and tetracycline. ChlamyCount was also able to measure the chlamydial growth-altering effect of drugs that influence host-bacterium interaction, such as gamma interferon, DEAE-dextran, and cycloheximide. ChlamyCount is an easily adaptable system for testing antichlamydial antimicrobials and other compounds that influence Chlamydia-host interactions. PCC00213相似文献

The TRPA1 Activator Allyl Isothiocyanate (AITC) Contracts Human Jejunal Muscle: Pharmacological Analysis 下载免费PDF全文
Zsolt Sandor Andras Dekany Dezsö Kelemen Timea Bencsik Robert Papp Lorand Bartho 《Basic & clinical pharmacology & toxicology》2016,119(3):341-342
The contractile effect of AITC (300 μM) on human jejunal longitudinal strips was inhibited by the TRPA1 antagonist HC 030031 and atropine or scopolamine, but was insensitive to tetrodotoxin, purinoceptor antagonists or capsaicin desensitization. It is concluded that TRPA1 activation stimulates a cholinergic mechanism in a tetrodotoxin‐resistant manner. 相似文献

Purpose
Studies comparing the outcome of spine surgery with that of large-joint replacement report equivocal findings. The patient-reported outcome measures (PROMs) used in such studies are typically generic and may not be sufficiently sensitive to the successes/failures of treatment. This study compared different indices of “success” in patients undergoing surgery for degenerative disorders of the lumbar spine, hip, or knee, using a validated, multidimensional, and joint-specific PROM.Methods
Preoperatively and 12 months postoperatively, 4594 patients (3937 lumbar spine, 368 hip, 269 knee) undergoing first-time surgery completed a PROM that included the Core Outcome Measures Index (COMI) for the affected joint. The latter comprises a set of single items on pain, function, symptom-specific well-being, quality of life, and disability—all in relation to the specified joint problem. Other single-item ratings of treatment success were made 12 months postoperatively.Results
In multiple regression analyses, controlling for confounders, the mean improvement in COMI at 12 months was greatest for the hip patients and lowest for those with degenerative spinal deformity (= the statistical reference group) (p < 0.05). Compared with spinal deformity, the odds of achieving “success” were: higher for hip (OR 4.6; 95% CI 2.5–8.5) and knee (OR 4.0; 95% CI 2.1–7.7) (no difference between spine subgroups) for “satisfaction with care”; higher for hip (OR 16.9; 95% CI 7.3–39.6), knee (OR 6.3; 95% CI 3.4–11.6), degenerative spondylolisthesis (OR 1.6; 95% CI 1.2–2.2), and herniated disc (OR 1.7; 95% CI 1.2–2.4) for “global treatment outcome”; and higher for hip (OR 13.8; 95% CI 8.8–21.6), knee (OR 5.3; 95% CI 3.6–7.8), degenerative spondylolisthesis (OR 1.6; 95% CI 1.3–2.1), and herniated disc (1.5; 95% CI 1.1–2.0) for “patient-acceptable symptom state”. Patient-rated complications were the greatest in degenerative spinal deformity (29%) and the lowest in hip (18%).Conclusions
The current study is the largest of its kind and the first to use a common, but joint-specific instrument to report patient-reported outcomes after surgery for degenerative disorders of the spine, hip, or knee. The findings provide a sobering account of the significantly poorer outcomes after spine surgery compared with large-joint replacement. Further work is required to hone the indications and patient selection criteria for spine surgery. The data should be used to lobby research funding-bodies, governmental agencies, industry, and charitable foundations to invest more in spine research/registries, in the hope of ultimately improving spine outcomes.Graphical abstract

Cytomegalovirus infection related changes frequently remain masked by local symptoms of tumor invasion or therapeutic side effects in cancer patients. The spectrum of cytomegalovirus manifestations, however, can be highly varied and may contribute to the failure of different organs with fatal outcome. The case of a 29-year-old female patient is presented who obtained polychemotherapy and allogenic stem cell transplantation following the diagnosis of classical Hodgkin's disease. Despite intensified treatment, only partial response could be achieved and the outcome of the disease was death. Postmortem examination revealed regressive lymph node infiltration as well as nodular liver and spleen manifestations of classical Hodgkin's disease. In addition, parenchymal tissues (lung, kidneys, small intestine, liver, pancreas and ovaries) showed the classical morphology of widespread cytomegalovirus infection. Bilateral enlargement of the ovaries was caused by a partially necrotic giant cell proliferation in the subepithelial cortex. CD30-negativity and cytomegalovirus antigen positivity of the large atypical cell infiltrate supported the diagnosis of cytomegalia oophoritis with morphological overlap between cytomegalovirus-infected giant cells and residual Hodgkin-Reed-Sternberg cells. Further to the cytopathic effect in multiple organs, significant hemophagocytosis was also observed in the spleen, liver and bone marrow. In summary, active cytomegalovirus infection may be a major cause of multi-organ failure in the immunosuppressed oncohematological patient. Careful postmortem analysis demonstrated both the activity of the viral infection and the efficacy of the anti-viral treatment, when applied. 相似文献

Intestinal alkaline phosphatase enzyme plays a pivotal role in the maintenance of intestinal mucosal barrier integrity with the detoxification capacity of lipopolysaccharide, the ligand of Toll-like receptor 4. The inappropriate immune responses and the damage of the mucosal barrier may contribute to the initiation of inflammatory bowel and celiac diseases. In the inflamed colonic mucosa of children with inflammatory bowel disease and in the duodenal mucosa of newly diagnosed children with celiac disease, the decreased intestinal alkaline phosphatase and increased Toll-like receptor 4 protein expression may generate enhanced lipopolysaccharide activity, which may strengthen tissue damaging processes. The enhancement of intestinal alkaline phosphatase activity in an animal model of colitis and in therapy resistant, adult patients with ulcerative colitis reduced the symptoms of intestinal inflammation. In accordance with these results, the targeted intestinal administration of the enzyme in the two examined disorders may be a supplemental therapeutic option in the future. 相似文献
