Publication date: Available online 16 September 2019Source: Carbohydrate PolymersAuthor(s): Jiaoyan Liu, Bing Yang, Minhui Li, Jing Li, Ying WanAbstractThiolated chitosan (CS-NAC) was synthesized and the selected CS-NAC was used together with silk fibroin (SF) to produce dual network CS-NAC/SF hydrogels. The CS-NAC/SF solutions with formulated compositions were able to form hydrogels at physiological temperature and pH. Rheological measurements showed that elastic modulus of some CS-NAC/SF gels could reach around 3 kPa or higher and was much higher than their respective viscous modulus, indicating that they behaved like st...

This study aimed to provide a better understanding of the altered molecular networks in BC from the gulf region. Herein, we compared the transcriptome of BC to adjacent normal tissue from six BC patients and identified 1,108 upregulated and 518 downregulated transcripts. A selected number of genes from the RNA-Seq analysis were subsequently validated using qRT-PCR. Differentially expressed (2.0-fold change, adj. p

We report on the use of a rhomboid flap for partial closure of a tracheal stoma. The rhomboid flap is a local flap that is frequently used by plastic surgeons because of its broad applications and not being very invasive. This is a low invasive and simple technique for partial closure of an excessively enlarged stoma.

This study sought to compare patient demographics, operative course, and peri-operative outcomes between unilateral and bilateral cleft patients. Primary cleft lip repairs were isolated from the National Surgical Quality Improvement Program Pediatric Database (NSQIP-P). Unilateral and bilateral cases of primary cleft lip were identified by ICD codes. Demographics, comorbidities, and post-operative outcomes were compared between cohorts. Patients were propensity matched to control for differences before repeating the analysis. About 4550 cleft lip repairs were evaluated over the 5-year period. Of the cases where the cleft t...

Haanstra and coauthors1 share the results from their randomized controlled trial assessing the impact of proximal colon chromoendoscopy for the detection of neoplasia at baseline and follow-up colonoscopy in patients with Lynch syndrome (LS) performed across 6 centers in the Netherlands. In the trial, indigo carmine chromoendoscopy application in the proximal colon was compared with standard white-light endoscopy (WLE) in 246 mismatch repair gene mutation carriers. Although chromoendoscopy led to a significantly increased median withdrawal time (19 vs 12 minutes), no improvement in the number of patients detected with neop...

Treatment of acute triangular fibrocartilage complex (TFCC) tear using arthroscopic suture repair has been used as a general treatment method, but it is difficult to obtain perfect results in all cases. We evaluated clinical and radiologic outcomes of the acute TFCC tear with distal radioulnar joint instability using the arthroscopic suture repair with pronator quadratus (PQ) advancement. Altogether, 80 patients (48 male, 32 female; mean ± SD age, 37.3 ± 11.5 years; mean ± SD follow-up, 23.7 ± 11.4 months) were enrolled in the study. Follow-up was at least 12 months (range, 12–38 months). ...

Conclusions Flexor tendon lacerations represent an important economic burden to our health care system, even when compared with other common hand conditions. Specifically, indirect costs, such as missed workdays, are the major contributor toward the total cost these injuries incur on society, accounting for upward of 89% of the total cost. This suggests that we should focus our efforts to improve treatments and rehabilitation protocols which decrease these indirect costs.

Conclusions The overall revision rate was 9.6%, which is relatively lower than that in other cleft centers. However, the repair technique and cleft care program should not be evaluated using the revision rate only. Various factors, including surgeons' preference, contribute to the indications for revision, and these factors can change with age. We plan to follow up the patients until our completion of the cleft care program and report the final revision rate.

Conclusions The CSA system is an appropriate source for harvesting dual skin paddle CASP flap. Use of this flap for the reconstruction of complex soft-tissue defects in the extremities in children is an alternative approach that reduces morbidity and improves the cosmetic outcome at the donor site.
