Paradoxical cases of psoriatic lesions induced or exacerbated by anti-tumor necrosis factor (TNF)-α therapy have been reported more frequently in recent years, but data related to inflammatory bowel disease (IBD) are rare. A systematic literature review was performed to provide information about this adverse effect in patients with IBD who receive anti-TNF therapy. Published studies were identified by a search of Medline, Embase, Cochrane, SciELO, and LILACS databases. A total of 47 studies (222 patients) fulfilled the inclusion criteria and were selected for analysis. Clinical and therapeutic aspects varied considerably among these reports. Of the 222 patients, 78.38% were diagnosed with Crohn's disease, and 48.20% were female. The mean patient age was 26.50 years, and 70.72% of patients had no history of psoriasis. Patients developed psoriasiform lesions (55.86%) more often than other types of psoriatic lesions, and infliximab was the anti-TNF-α therapy that caused the cutaneous reaction in most patients (69.37%). Complete remission of cutaneous lesions was observed in 63.96% of the cases. We found that psoriatic lesions occurred predominantly in adult patients with Crohn's disease who received infliximab and had no previous history of psoriasis. Most patients can be managed conservatively without discontinuing anti-TNF-α therapy.

Background: Autologous free fat graft outcomes are not always predictable, and variables that can potentially influence fat graft retention are still not well understood or investigated. The purposes of this study were to assess fat graft retention in the management of craniofacial contour deformities and to identify possible predictive factors of this retention. Methods: A prospective analysis was conducted using consecutive patients with unilateral craniofacial contour deformities who underwent autologous free fat grafting between 2012 and 2015. Standardized ultrasonographic craniofacial soft-tissue thickness measurements were adopted to determine the fat graft retention. Bivariate and multivariate analyses were performed to identify independent predictors of 12-month postoperative fat graft retention. Results: One hundred forty-two patients were enrolled. There was significant (all p < 0.05) and progressive reduction in fat graft retention within the first 3 postoperative months, and the retained fat graft was maintained (all p > 0.05) from 3 to 12 months postoperatively, with a 12-month fat graft retention rate of 67.7 percent. Age, Parry-Romberg syndrome, previous craniofacial bone surgery, grafted volume, and forehead unit were independently negative (all p < 0.05) predictors of fat graft retention, whereas cheek unit was an independently positive (all p < 0.05) predictor of retention. Conclusion: Craniofacial fat graft retention is achievable but remains somewhat unpredictable, with age, Parry-Romberg syndrome, previous bone surgical intervention, grafted volume, and recipient sites affecting retention. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, III.

Background: A recent artificial intelligence–based investigation has shown the impacts of orthognathic surgery on the patient’s facial appearance and apparent age. However, appearance and age perception as reported by patients and surgical professionals have not been addressed in the same cohort to date. Methods: FACE-Q facial appraisal (appearance and age) and quality-of-life scale scores obtained before and after orthognathic surgery, in addition to three-dimensional photographs of 70 patients with skeletal class III deformity, were collected for a comparative cross-sectional study. Seven blinded plastic surgeons rated all photographs for apparent facial aesthetic and age scales. The FACE-Q data from 57 matched normal individuals were adopted for the comparative analyses. The correlation between the FACE-Q and the professional-based scales was tested. Results: Pre–orthognathic surgery versus post–orthognathic surgery comparisons showed significant differences (p < 0.001) for all FACE-Q scales and panel assessments, with higher (FACE-Q scales and professional-based aesthetic parameters) and lower (FACE-Q patient-perceived age scale and professional-based age parameter) values for post–orthognathic surgery measurements. Patients had significantly (p < 0.001) higher (patient-perceived age scale) and lower (facial appraisal and quality-of-life scales) FACE-Q values than normal individuals for pre–orthognathic surgery but not for post–orthognathic surgery measurements. The FACE-Q facial appearance overall scale had significant correlations (p < 0.001) with the panel assessment for the parameters “beautiful” and “attractive” but not for the “pleasant” parameter. No significant correlations were observed for facial age scales. Conclusion: This study contributes to the orthognathic surgery literature by revealing that orthognathic surgery positively impacts the perception of apparent facial age and improves facial appearance and quality of life. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

Nasal deformity is associated with congenital cleft lip and palate. Primary rhinoplasty for reconstruction of the nasal deformity at the time of bilateral cleft lip repair is a controversial issue in cleft care due to traditional teaching concerning the potential impairment of nasal growth. This study assessed long-term nasal growth in patients with bilateral cleft lip and palate who underwent primary rhinoplasty by a single surgeon between 1995 and 2002 and reached skeletal maturity (n = 39; mean: 19 ± 2 years). Normal age-, gender-, and ethnicity-matched subjects (n = 52) were enrolled for comparative analyses. Three-dimensional nasal photogrammetric measurements (10 linear, 4 angular, 6 proportional, 1 surface area, and 1 volume parameter) were collected from patients with bilateral cleft lip and palate and normal subjects. Patients who underwent rhinoplasty presented with significantly (all p < 0.05) smaller nasal tip projection and nasal tip angles, but greater values for nasal dorsum length, nasal protrusion, alar width, columellar height, dome height, columellar angle, labiocolumellar angle, nasal tip height ratio, nasal index, alar width/intercanthal distance ratio, and alar width/mouth width ratio compared to normal subjects. There were no differences (all p > 0.05) in nasal height, tip/midline deviation, nasal dorsum angle, dome-to-columella ratio, columella height/alar width ratio, area surface, and volume parameters between the two groups. This study shows that primary rhinoplasty performed in patients with bilateral cleft lip and palate during infancy does not result in deficiency of the nasal dimensions relative to controls.

Background: The purpose of this study is to review 10 years of surgical experience in the management of Apert syndrome, focusing on an updated algorithm which includes hand reconstruction and posterior vault distraction osteogenesis (PVDO). Additionally, the authors compare PVDO, which is currently used, with fronto-orbital advancement (FOA), which was utilized in a previous algorithm. Methods: An observational retrospective study was performed on consecutive patients with Apert syndrome who underwent upper and lower limb reconstruction and craniofacial surgery between 2007 and 2017. A modified Clavien–Dindo surgical complication scale was used to stratify complications between PVDO and FOA. Demographic, surgical, and outcome data was also recorded. The blood transfusion rate between PVDO and FOA was also assessed and compared utilizing the Student t test. Results: The present study included 69 patients with Apert syndrome (34 males and 35 females). Craniofacial surgeries were performed on a total of 38 patients. A total of 210 operations were performed on the respective upper and lower limbs of patients included in this study. A total of 18 patients underwent PVDO (n = 9) and FOA (n = 9). Posterior vault distraction osteogenesis required significantly less transfused blood volume than FOA (P < 0.05). Complication rate and length of hospital stay were similar for each procedure. Conclusion: An updated algorithm to treat Apert patients was implemented. Posterior vault distraction osteogenesis incorporated into an updated algorithm results in a lower blood transfusion rate.
