Mesh abdominoplasty for rectus diastasis in women and men

Purpose

Meshes clearly have improved outcomes for tissue approximation over suture repairs for incisional hernias. A knowledge gap exists as to the surgical complication rate and post-operative outcomes of a mesh rectus diastasis repair with a narrow well-fixed mesh that simultaneously narrows the rectus muscles and closes the widened linea alba.

Methods

Inclusion criteria for mesh abdominoplasty were patients who (1) underwent a retrorectus planar mesh for repair of rectus diastasis (2) did not have a concurrent incisional hernia and (3) underwent skin tailoring as part of a cosmetic aspect of their care. The primary endpoint was surgical site occurrence (SSO) at any time after surgery as determined with review of their office and hospital medical records. Secondary endpoints included the length and complexity of the return to the operating room for any reason, non-surgical complications, readmission, post-operative recovery, surgical site infection, recurrence/persistence of abdominal wall laxity, and soft tissue revision rates.

Results

SSO rate was 0% for the 56 patients who underwent this procedure. There were 40 women and 16 men. Superficial infections requiring oral antibiotics were required in three patients. One was a drain site erythema, one was for a superficial stitch abscess, and the third was for a mesh strip knot infection 6 months after the procedure. One patient underwent further tightening of the abdominal wall. Rates of soft tissue revision in the office for improved cosmesis were 23% in women and 6% in men.

Conclusion

Repair of rectus diastasis with a narrow well-fixed mesh and concurrent skin abdominoplasty is a well-tolerated and reliable procedure with low recurrence and low SSO in the manner described. It is a procedure that works for both female and male pattern rectus diastasis, and has become our procedure of choice for moderate and severe rectus diastasis.

Effectiveness of Internet-based interventions in managing chemotherapy-related symptoms in patients with cancer: a systematic literature review

PURPOSE

The aims of this review were to (1) examine the effectiveness of Internet-based interventions on cancer chemotherapy-related physical symptoms (severity and/or distress) and health-related quality of life (HRQOL) outcomes and (2) identify the design elements and processes for implementing these interventions in oncology practices.

METHODS

A systematic review was performed. The Cochrane Database of Systematic Reviews, and Cochrane Central Register of Controlled Trials, EMBASE, MEDLINE, CINAHL, and PsycINFO were searched for studies dating from January 2000 through to October 2016. Based on pre-determined selection criteria, data was extracted from eligible studies. Methodological quality of studies was assessed using an adapted version of the Cochrane Collaboration Back Review Group checklist.

RESULTS

The literature search yielded 1766 studies of which only six RCTs fulfilled the eligibility criteria. Although the content, duration, and frequency of interventions varied considerably across studies, commonly used elements included tailored information, education, self-management support, and communication with clinicians. Five studies measured symptom distress and four of them reported statistically significant differences between study groups. Of the three studies that measured HRQOL, two reported improvement (or no deterioration over time) for the intervention group. However, several methodological issues including high attrition rates, poor adherence to interventions, and use of non-validated measures affect confidence in the strength of evidence.

CONCLUSION

Despite the evidence in support of using the Internet as a worthwhile tool for effective patient engagement and self-management of chemotherapy-related symptoms outside clinic visits, methodological limitations in the evidence base require further well-planned and quality research.

Translation and psychometric assessment of the Persian version of the Rhodes Index of Nausea, Vomiting and Retching (INVR) scale for the assessment of chemotherapy-induced nausea and vomiting

No tools are available to assess or measure the experience of chemotherapy-induced nausea and vomiting (CINV) for Persian/Farsi speakers. The purpose of this study is to translate the Rhodes Index of Nausea, Vomiting and Retching (INVR) scale for use with Persian-speaking cancer patients. A sample of 94 cancer patients were recruited from a cancer research centre in Mashhad-Iran. A standard two phase process of scale translation and validation was conducted. In phase I, standard 'forward-backward' translation procedure was used to translate the original version of the INVR questionnaire into Persian. The translated questionnaire was reviewed and revised and a Persian version of the scale was produced. In the second phase, a multiphase instrumentation study describing the internal consistency and test-retest reliability of the translated version was conducted. The inter-item correlation measured by Cronbach's alpha was 0.88. Test/re-test reliability was measured by the weighted kappa and was between 0.63 and 0.79, indicating 'substantial agreement' and stability between the initial and subsequent administrations for each item. These results demonstrate that the Persian version of the INVR is acceptable for use among Iranian cancer patients. Researchers could use this study as a model for future translation and application of psychometric instrumentation.

Improving the performance of computer color matching procedures

A premise was set up entailing the possibility of a synergistical combination of advantages of spectrophotometric and colorimetric matching procedures. Attempts were therefore made to test the performances of fifteen matching procedures, all based on the Kubelka-Munk theory, including two procedures utilizing the fundamental color stimulus R(FCS) of the spectral decomposition theory. Color differences CIE DeltaE(00) as well as concentration differences DeltaC(AVE) were used to theoretically rank the fifteen color matching procedures. Results showed that procedures based on R(FCS) were superior in accurately predicting colors and concentrations. Additionally, the metameric black component R(MB) of the decomposition theory also showed promise in predicting degrees of metamerism. This preliminary study, therefore, provides evidence for the premise of this investigation.

Corneal topographic changes after scleral buckling

PURPOSE

To evaluate corneal topographic changes and induced corneal astigmatism after scleral buckling (SB).

METHODS

This interventional case series includes all patients who had undergone scleral buckling for rhegmatogenous retinal detachment (RRD) during a 1-year period. Patients were divided into four groups according to type and extent of scleral buckling which depended on the discretion of a retina specialist. Videokeratography was performed for all patients preoperatively and repeated 1 and 3 months after SB.

RESULTS

Thirty-nine eyes of 39 patients (29 male, 74.7%) with mean age of 50.35+/-20 years (range 13-80) were finally analyzed. There was no statistically significant difference among the groups in terms of preoperative corneal astigmatism, surface regularity index (SRI), surface asymmetry index (SAI), mean keratometry (mean K), and potential visual acuity (PVA ). Overall, preoperative mean K was 43.97+/-1.78 D, which reached 44.2+/-2.02 D and 43.92+/-2.16 D 1 and 3 months after the operation. Mean preoperative SRI was 0.58+/-0.4, which increased to 1.24+/-1.18 and 1.29+/-1.13 1 and 3 months after the operation respectively. Mean preoperative SAI was 0.39+/-0.21, which increased to 0.73+/-0.37 and 0.75+/-0.66 1 and 3 months after the procedure. Changes in SAI at 1 and 3 months following SB were significant (p values <0.001); however, these postoperative values were not significantly different. Mean preoperative PVA was 0.07+/-0.75 logMAR (equivalent to 20/20) but decreased to 0.24+/-0.25 (equivalent to 20/30) and 0.27+/-0.29 (equivalent to 20/40) 1 and 3 months after SB, respectively.

CONCLUSIONS

Significant changes in corneal topographic indices including increases in SRI and SAI and a concomitant decrease in PVA may occur after SB procedures. These induced changes must be considered and appropriately addressed postoperatively to provide the best possible corrected vision.
