Pseudomonas aeruginosa sepsis with ecthyma gangrenosum and pseudomembranous pharyngolaryngitis in a 5-month-old boy
Pseudomonas aeruginosa infection that induced pseudomembranous laryngopharyngitis and ecthyma gangrenosum simultaneously in a healthy infant is rare. We reported on a previously healthy 5-month-old boy with initial presentation of fever and diarrhea followed by stridor and progressive respiratory distress. P. aeruginosa sepsis was suspected because ecthyma gangrenosum over the right leg was found at the emergency department, and the diagnosis was confirmed by the blood culture. Fiberscope revealed bacterial pharyngolaryngitis without involvement of the trachea. Because of early recognition and adequate treatment, including antimicrobial therapy, noninvasive ventilation, incision, and drainage, he recovered completely without any complications
Phosphorylation at Ser473 regulates heterochromatin protein 1 binding and corepressor function of TIF1beta/KAP1
<p>Abstract</p> <p>Background</p> <p>As an epigenetic regulator, the transcriptional intermediary factor 1Ī² (TIF1Ī²)/KAP1/TRIM28) has been linked to gene expression and chromatin remodeling at specific loci by association with members of the heterochromatin protein 1 (HP1) family and various other chromatin factors. The interaction between TIF1Ī² and HP1 is crucial for heterochromatin formation and maintenance. The HP1-box, PXVXL, of TIF1Ī² is responsible for its interaction with HP1. However, the underlying mechanism of how the interaction is regulated remains poorly understood.</p> <p>Results</p> <p>This work demonstrates that TIF1Ī² is phosphorylated on Ser473, the alteration of which is dynamically associated with cell cycle progression and functionally linked to transcriptional regulation. Phosphorylation of TIF1Ī²/Ser473 coincides with the induction of cell cycle gene <it>cyclin A2 </it>at the S-phase. Interestingly, chromatin immunoprecipitation demonstrated that the promoter of <it>cyclin A2 </it>gene is occupied by TIF1Ī² and that such occupancy is inversely correlated with Ser473 phosphorylation. Additionally, when HP1Ī² was co-expressed with TIF1Ī²/S473A, but not TIF1Ī²/S473E, the colocalization of TIF1Ī²/S473A and HP1Ī² to the promoters of <it>Cdc2 </it>and <it>Cdc25A </it>was enhanced. Non-phosphorylated TIF1Ī²/Ser473 allowed greater TIF1Ī² association with the regulatory regions and the consequent repression of these genes. Consistent with possible inhibition of TIF1Ī²'s corepressor function, the phosphorylation of the Ser473 residue, which is located near the HP1-interacting PXVXL motif, compromised the formation of TIF1Ī²-HP1 complex. Finally, we found that the phosphorylation of TIF1Ī²/Ser473 is mediated by the PKCĪ“ pathway and is closely linked to cell proliferation.</p> <p>Conclusion</p> <p>The modulation of HP1Ī²-TIF1Ī² interaction through the phosphorylation/de-phosphorylation of TIF1Ī²/Ser473 may constitute a molecular switch that regulates the expression of particular genes. Higher levels of phosphorylated TIF1Ī²/Ser473 may be associated with the expression of key regulatory genes for cell cycle progression and the proliferation of cells.</p
Use of Rubber Dams During Root Canal Treatment in Taiwan
Background/PurposeIsolation of teeth with rubber dams is an important procedure for infection control in dentistry, especially in endodontic treatment. This study surveyed the prevalence of rubber dam usage in nonsurgical root canal treatment (RCT) by dentists under the National Health Insurance system in Taiwan.MethodsA total of 1,332 completed RCT cases were randomly selected from a large database from the Bureau of National Health Insurance in Taiwan in 2004. The radiographs and dental charts of the selected cases were evaluated for the prevalence of rubber dam usage in RCT. The frequencies of rubber dam usage for RCT by dentists were compared between hospitals and private dental clinics and among six different regions in Taiwan.ResultsThe overall prevalence of rubber dam usage for RCT by dentists under the National Health Insurance system in Taiwan was 16.5%. The frequency of rubber dam usage for RCT by dentists in hospitals (32.8%) was significantly higher than that (10.3%) in private dental clinics (p < 0.0001). However, there was no significant difference in the frequency of rubber dam usage for RCT by dentists among six different geographic regions in Taiwan.ConclusionThe prevalence of rubber dam usage for RCT by dentists in Taiwan is relatively low. Because rubber dam isolation of an endodontically-treated tooth can provide better infection control, increase patient protection, and improve treatment efficiency, there is an urgent need to advise dentists in Taiwan to use rubber dams for every RCT case
The Antiinfective Effects of Velvet Antler of Formosan Sambar Deer (Cervus unicolor swinhoei) on Staphylococcus aureus-Infected Mice
We assayed the effects of velvet antler (VA) of Formosan sambar deer (Cervus unicolor swinhoei) and its extracts on the anti-infective activity against pathogenic Staphylococcus aureus in vitro and in vivo in this study. In vitro data indicated that the VA extracts stimulated the proliferation of resting splenocytes and macrophages in a dose-dependent manner up to the highest concentration used (150āĪ¼gāmLā1). The production of proinflammatory cytokines (TNF-Ī±, IL-6, IL-12) by lipoteichoic acid was significantly suppressed after being cocultured with the VA extracts in a dose-dependent manner. Animal test in S. aureus-infected mice demonstrated that the numbers of bacteria determined in the kidneys and peritoneal lavage fluid of S. aureus-infected mice were significantly higher than those found in the same organs of mice pretreated with the VA samples. Moreover, the highly enhanced phagocytic activity of macrophages was further verified after in vitro treatment with the VA samples. The protective mechanisms of the VA samples might include an immune enhancer and an inflammatory cytokine suppressor
Comparing the outcomes of two strategies for colorectal tumor detection: Policy-promoted screening program versus health promotion service
AbstractBackgroundThe Taiwanese government has proposed a population-based colorectal tumor detection program for the average-risk population. This study's objectives were to understand the outcomes of these screening policies and to evaluate the effectiveness of the program.MethodsWe compared two databases compiled in one medical center. The āpolicy-promoted cancer screeningā (PPS) database was built on the basis of the policy of the Taiwan Bureau of National Health Insurance for cancer screening. The āhealth promotion serviceā (HPS) database was built to provide health check-ups for self-paid volunteers. Both the PPS and HPS databases employ the immunochemical fecal occult blood test (iFOBT) and colonoscopy for colorectal tumor screening using different strategies. A comparison of outcomes between the PPS and HPS included: (1) quality indicatorsācompliance rate, cecum reaching rate, and tumor detection rate; and (2) validity indicatorsāsensitivity, specificity, positive, and negative predictive values for detecting colorectal neoplasms.ResultsA total of 10,563 and 1481 individuals were enrolled in PPS and HPS, respectively. Among quality indicators, there was no statistically significant difference in the cecum reaching rate between PPS and HPS. The compliance rates were 56.1% for PPS and 91.8% for HPS (pĀ <Ā 0.001). The advanced adenoma detection rates of PPS and HPS were 1.0% and 3.6%, respectively (pĀ <Ā 0.01). The carcinoma detection rates were 0.3% and 0.4%, respectively (pĀ =Ā 0.59). For validity indicators, PPS provides only a positive predictive value for colorectal tumor detection. HPS provides additional validity indicators, including sensitivity, specificity, positive predictive value, and negative predictive value, for colorectal tumor screening.ConclusionIn comparison with the outcomes of the HPS database, the screening efficacy of the PPS database is even for detecting colorectal carcinoma but is limited in detecting advanced adenoma. HPS may provide comprehensive validity indicators and will be helpful in adjusting current policies for improving screening performance
Exercise training with negative pressure ventilation improves exercise capacity in patients with severe restrictive lung disease: a prospective controlled study
BACKGROUND: Exercise training is of benefit for patients with restrictive lung disease. However, it tends to be intolerable for those with severe disease. We examined whether providing ventilatory assistance by using negative pressure ventilators (NPV) during exercise training is feasible for such patients and the effects of training. METHODS: 36 patients with restrictive lung disease were prospectively enrolled for a 12-week multidisciplinary rehabilitation program. During this program, half of them (n:18; 60.3āĀ±ā11.6Ā years; 6 men; FVC: 32.5āĀ±ā11.7% predicted ) received regular sessions of exercise training under NPV, whilst the 18 others (59.6āĀ±ā12.3Ā years; 8 men; FVC: 37.7āĀ±ā10.2% predicted) did not. Exercise capacity, pulmonary function, dyspnea and quality of life were measured. The primary endpoint was the between-group difference in change of 6Ā minute-walk distance (6MWD) after 12Ā weeks of rehabilitation. RESULTS: All patients in the NPV-exercise group were able to tolerate and completed the program. The between-group differences were significantly better in the NPV-exercise group in changes of 6MWD (34.1āĀ±ā12.7Ā m vs. -32.5āĀ±ā17.5Ā m; Pā=ā0.011) and St George Score (ā14.5āĀ±ā3.6 vs. 11.8āĀ±ā6.0; Pā<ā0.01). There was an improvement in dyspnea sensation (Borgās scale, from 1.4āĀ±ā1.5 point to 0.8āĀ±ā1.3 point, Pā=ā0.049) and a small increase in FVC (from 0.85āĀ±ā0.09Ā L to 0.91āĀ±ā0.08Ā L, Pā=ā0.029) in the NPV-exercise group compared to the control group. CONCLUSION: Exercise training with NPV support is feasible for patients with severe restrictive lung diseases, and improves exercise capacity and health-related quality of life
Na,K-ATPase activity promotes macropinocytosis in colon cancer via Wnt signaling
Recent research has shown that membrane trafficking plays an important role in canonical Wnt signaling through sequestration of the Ī²-catenin destruction complex inside multivesicular bodies (MVBs) and lysosomes. In this study, we introduce Ouabain, an inhibitor of the Na,K-ATPase pump that establishes electric potentials across membranes, as a potent inhibitor of Wnt signaling. We find that Na,K-ATPase levels are elevated in advanced colon carcinoma, that this enzyme is elevated in cancer cells with constitutively activated Wnt pathway and is activated by GSK3 inhibitors that increase macropinocytosis. Ouabain blocks macropinocytosis, which is an essential step in Wnt signaling, probably explaining the strong effects of Ouabain on this pathway. In Xenopus embryos, brief Ouabain treatment at the 32-cell stage, critical for the earliest Wnt signal in development-inhibited brains, could be reversed by treatment with Lithium chloride, a Wnt mimic. Inhibiting membrane trafficking may provide a way of targeting Wnt-driven cancers
