Pressure Masks for Facial Scar Treatment after Oncological Reconstruction: Long-Term Patient Satisfaction and Quality of Life

INTRODUCTION

 With increasing incidence of facial skin cancer, more patients undergo facial reconstruction following Mohs micrographic surgery (MMS). Aesthetically unpleasing, thickened facial flaps, and disturbing scars can be treated with a pressure mask with inner silicone lining to help improve functional and aesthetic outcomes. However, data on long-term patient satisfaction and quality of life (QoL) following this treatment are lacking.

METHODS

 We aimed to assess long-term satisfaction and QoL of patients who underwent local flap reconstruction following MMS. Patients treated between January 2012 and October 2020 were invited to answer FACE-Q and SCAR-Q questionnaires. Demographic data, skin cancer type and location, type of reconstruction, postoperative complications, duration of pressure mask therapy, daily compliance, and additional scar treatment were collected to explore possible predictors.

RESULTS

 Of 92 eligible patients, 50 responded. Eighteen respondents were male (36%) and 32 were female (64%). Mean duration of pressure mask therapy was 10.20 ± 4.61 months. Patients were 61.14 ± 32.91 months after completion of pressure mask therapy upon participation. Patients whose reconstruction consisted of multiple flaps had significantly worse outcomes in social function (p = 0.012), scar appearance (p = 0.045), and scar symptoms (p = 0.008). A trend of increasing time since therapy completion predicting better outcomes was observed for all scales, and it was a significant predictor for better scar appearance (p = 0.001) and less scar symptoms (p = 0.001).

CONCLUSION

 Pressure mask treatment for facial flaps and scars following MMS results in good long-term patient satisfaction and QoL. Multiple local flaps, reflecting a larger skin defect postexcision, is a predictor for worse outcomes in social function, scar appearance, and symptoms. Increasing time is associated with increasing satisfaction, which reflects satisfactory and stable long-term effects of treatment, possibly combined with more acceptance of the result over time.

Clinical effects of transparent facial pressure masks: A literature review

BACKGROUND

Severe facial hypertrophic scars are known to severely impact emotional well-being. Pressure therapy by means of transparent face masks has been used for almost 40 years, but evidence about the clinical effects remains sparse.

OBJECTIVES

To provide a summary on the efficacy of transparent face masks in the treatment of facial hypertrophic scars.

METHODS

A literature search was conducted in PubMed, MEDLINE, and Cochrane databases through 1 January 2018. Articles describing the clinical effects of facial pressure therapy for remodeling the face after trauma or surgery with a validated tool were included. This review included studies of participants treated with facial hypertrophic scars, both minors and adults.

RESULTS

Three articles involving 33 patients were selected for inclusion. Two studies described statistically significant improvement in facial scars measured by durometer, ultrasound, and the Patient and Observer Scar Assessment Scale (POSAS).

CONCLUSIONS

Facial pressure masks have been shown to deliver significant improvement in facial scars, measured by both subjective and objective tools. However, only three studies could be included in this literature review. Also, because of considerable limitations of the studies, it remains difficult to draw substantial conclusions about the efficacy of transparent face masks.

CLINICAL RELEVANCE

This literature review provides a summary of the current evidence on the subjectively and objectively measured clinical effects of transparent face masks in the treatment of facial scars, highlighting the need for further research on this topic.

Manual fabrication of a specialized transparent facial pressure mask: A technical note

BACKGROUND AND AIM

The objective of this study was to describe the manual fabrication of a transparent facial pressure mask for treating facial deformities. The mask combines the use of a silicone inner liner and mechanical pressure in the facial region.

TECHNIQUE

A negative mold is formed by covering the face with plaster. Manipulation of soft tissue is a crucial part in this process. After hardening and removal of the negative mold, the positive mold is formed and dried. Next a rolled silicone sheet is placed over the positive mold in a vacuum environment. Subsequently, the silicones are vulcanized. Then the rigid outside of the mask is created. The silicone inner liner and outside shell are then affixed.

DISCUSSION

This described technique results in accurate facemasks with precise fitting. During therapy, the mask is adjusted multiple times to keep excellent fit, as remodeling of scars and deformities takes place.

CLINICAL RELEVANCE

Facemasks are a reputable therapeutic modality to reduce excessive facial scarring. They require excellent fitting to give pleasing results. To provide a better understanding of facemask therapy, this study describes the manual fabrication technique.

Satisfaction with Facial Appearance and Quality of Life after Treatment of Face Scars with a Transparent Facial Pressure Mask

Treatment of facial hypertrophic scars and deformities has developed from the use of elastic fabric hoods to transparent facemasks. The clinical effects of these masks have been described. However, the psychological impact of wearing such a mask is not well documented. The aim of this study was to assess patients' satisfaction with their current facial appearance, to assess the end result of facemask therapy, and to assess the decision to have undergone facemask therapy by means of four different FACE-Q questionnaires. Out of the eligible 87 patients who completed the facemask therapy between January 2012 and November 2017, 42 filled out the questionnaires. These patients wore a custom-fabricated facemask because of facial hypertrophic scars and severe postsurgical facial irregularities. Patients who wore the mask 12 to 16 hours per day were significantly more satisfied with the end result compared with those who wore it 4 to 8 hours daily. Also, patients who wore the mask 8 to 12 and 12 to 16 hours each day were more satisfied to have undergone therapy compared with those who wore it 4 to 8 hours daily. Furthermore, patients who finished therapy 3 to 4 years and 4 to 5 years ago reported a significant higher satisfaction with facial appearance compared with those who completed therapy in a time period shorter than 1 year ago. Patients who finished therapy 3 to 4 years ago reported higher satisfaction with their facial appearance compared with those who finished therapy 2 to 3 years ago. Additionally, the Patient and Observer Scar Assessments Score (POSAS) showed a significant reduction between start and end of therapy. This study shows facemask therapy to result in long-lasting stable results. It also shows a longer daily wearing of the facemask to result in the highest satisfaction according to patients.

Effects of selective α2 -adrenergic receptor agonists on electrical field-stimulated contractions of isolated bronchi in horses

We investigated the effects of different selective α₂ -adrenergic receptor (AR) agonists (detomidine, medetomidine, xylazine, and brimonidine) on the contractions of horse-isolated bronchi induced by electrical field stimulation (EFS) and by carbachol. No effects were observed on the contraction induced by carbachol, while α₂ -AR agonists reduced EFS-evoked contractions in a concentration-related fashion. The rank order of potency (pD₂ ) was brimonidine (7.40 ± 0.20) >medetomidine (7.09 ± 0.24) >detomidine (6.13 ± 0.55) >xylazine (4.59 ± 0.16). The maximal effects (E_max ) were -56.3% ± 6.3%, -40.4% ± 6.9%, -48.6% ± 9.9%, and -72.7% ± 12.7% for brimonidine, medetomidine, detomidine, and xylazine, respectively. Adrenergic block by guanethidine enhanced the potency (8.10 ± 0.05, 7.30 ± 0.15, 6.83 ± 0.41, and 5.40 ± 0.22) and the efficacy (-95.2% ± 0.7%, -45.2% ± 11.7%, -58.5% ± 9.8%, and -97.9% ± 0.6%) of brimonidine, medetomidine, detomidine, and xylazine, respectively. Selective α₂ -AR antagonist, atipamezole, competitively antagonized the inhibition of EFS-evoked contractions induced by all agonists except xylazine. These results suggest the existence of presynaptic α₂ -ARs on cholinergic neurons, negatively regulating the release of acetylcholine in horse bronchial muscle, and that α₂ -AR agonists may be beneficial against vagally mediated bronchoconstriction.

A new treatment of hypertrophic and keloid scars with combined triamcinolone and verapamil: a retrospective study

Background

Since the management of keloid and hypertrophic scars still remains a difficult clinical problem, there is need for adequate, effective therapy. In this study, we explored for the first time the efficacy and the potential synergetic effect of combined triamcinolone and verapamil for the treatment of hypertrophic and keloid scars. The objective was to assess the efficacy of combined intralesional triamcinolone and verapamil therapy for hypertrophic and keloid scars.

Methods

Fifty-eight patients with hypertrophic scars (n = 31) and keloid scars (n = 27) were included. A specific injection therapy scheme was applied. Five follow-up moments were chosen, with a maximum follow-up of nearly 2 years. The effects of combination therapy on scar pliability, thickness, relief, vascularization, surface area, pain, and pruritus were examined by means of the Patient and Observer Scar Assessment Scale (POSAS).

Results

Our results reveal a fast and abiding improvement of both keloid and hypertrophic scars after treatment with the combination therapy. All POSAS components showed a reduction in scar score, while scar relief, pain, itchiness, and surface area improved significantly (P < 0.05) in keloids. Significant improvement in hypertrophic scars was found in scar pigmentation, vascularization, pliability, thickness, pain, and surface area. Overall POSAS scores revealed statistically significant decreases between baseline and 3–4 months, 4–6 months, and >12 months after start of therapy in both keloids and hypertrophic scars.

Conclusions

This study reveals that combined therapy of triamcinolone and verapamil results in overall significant scar improvement with a long-term stable result.

Level of evidence: Level IV, therapeutic study.

Preliminay study for the Italian validation of the screen for cognitive impairment in psychiatry (SCIP)

Introduction

The screen for cognitive impairment in psychiatry (SCIP) is a brief, accessible scale designed for detecting cognitive deficits in psychiatric disorders.

Objectives

The objective of this study is to test the SCIP's validity as a cognitive test by comparison with standard neuropsychological scale using the Pearson's correlation.

Aims Test the convergent and discriminant validity of the SCIP within the Italian SCIP validation project.

Methods

Patients between 18 and 65 years who are in a stable phase of the disease, diagnosed with schizophrenia, schizoaffective disorder or bipolar I disorder were enrolled in this study, from the community mental health department of Ferrara.

Results

The tests were administered to 110 patients (mean age: 45 ± 11,4) and to 86 controls (mean age: 35 ± 12,6) of both sex. SCIP presents high correlation with the R-BANS total score (P < 0.01) and the subscales (verbal learning test-immediate, working memory, verbal fluency test, verbal learning test-delayed, processing speed test, P < 0.01). There are significant differences (P < 0.01) in all SCIP dimensions between patient and control group (Table 1).

Conclusions

Our analysis confirm the results of the English, French and Spanish version of the SCIP regarding convergent and discriminant validity. The SCIP represents a valid, simple and brief screening tool for the cognitive evaluation of patients with schizophrenia-spectrum disorders.

Helmet versus nonhelmet treatment in nonsynostotic positional posterior plagiocephaly

A total of 105 infants with nonsynostotic posterior plagiocephaly were treated using a helmet or by head positioning. Effect of treatment was scored using a cosmetic outcome score (0-10 points) assigned by the parents. The onset of the observed skull deformity correction was not different for the helmet vs. nonhelmet treatment. Improvement was significantly better and faster in the helmet group compared with nonhelmet treatment (p < 0.01 and p < 0.001, respectively).

Analysis of gastroduodenitis and oesophagitis in relation to dyspeptic/reflux symptoms

BACKGROUND/AIMS

The pathogenesis of dyspeptic/reflux symptoms and the clinico-pathologic profile of affected patients are still poorly understood. To improve our knowledge in this field we carried out a systematic, comparative analysis of symptom profiles and histopathologic patterns of oesophagogastroduodenal mucosa in a series of 221 subjects, 140 with and 81 without endoscopic evidence of hiatal hernia. Of these, 190 showed reflux and/or dyspeptic symptoms.

METHODS

Before endoscopy, all the subjects were questioned about the presence and severity of 12 individual symptoms. Biopsies were taken from the distal oesophagus, cardia, corpus, angulus, antrum and duodenal bulb, and were scored in accordance with the Sydney system.

RESULTS

Patient groups with a distinct clinico-pathologic profile were better identified when symptoms of adequate severity were compared with histopathologic parameters. A correlation between gastroesophageal reflux disease (GORD) symptoms and histologic signs of oesophagitis was mostly restricted to patients endoscopically positive for oesophagitis. Retroxiphoid pyrosis correlated with cardial gastritis but not with oesophagitis, either endoscopic or histologic, while ulcer-like epigastric pain correlated with active duodenitis and distal gastritis. No definite histopathologic background was detected in patients with putative dysmotility-like symptoms, endoscopy-negative GORD and low score or mixed symptoms.

CONCLUSION

A contribution of Helicobacter pylori gastroduodenitis to the pathogenesis of some dyspeptic symptoms seems likely. However, the identification of specific histologic changes causing individual symptoms remains rather elusive, with the exception of active antroduodenitis in patients with ulcer-like pain and of active proximal gastritis in patients with severe retroxiphoid pyrosis.

[Therapeutic and prophylactic role of mesalazine (5-ASA) in symptomatic diverticular disease of the large intestine. 4 year follow-up results]

In order to evaluate the efficacy and tolerability of mesalazine (5-ASA) in the prophylaxis of symptomatic relapses, of major complications and of microhemorrhagic phenomena in diverticular disease of the large intestine (MDC), prospective clinical study was conducted on patients with light-moderate symptomatic MDC under treatment with sulbactam-ampicillin 1.5 g/12 h i.m. and rifaximine 400 mg/12 h per os for 7 days. Follow-up period of 5 years with seriated checkups and laboratory and instrumentation controls. End points are represented by the relapse on inflammation and/or by the occurrence of major complications. On enrollment, 166 patients were randomized to receive mesalazine (Pentacol tablets--SOFAR S.p.A.) 400 mg b.i.d. per os for 8 weeks (81 patients; group M) or no supplementary treatment (85 patients; group C). After 4 years of follow-up, 44 patients dropped out of the study (9 because of major complications, 3 for massive hemorrhage, and 32 drop outs). Symptomatic relapses occurred in 51 patients (12 M; 39 C), while minor diverticular hemorrhages occurred in 43 patients (12 M; 31 C), with an estimated probability of remaining free respectively from symptomatic relapse (p=0.00005) and from microhemorrhagic phenomena (p=0.001) decisively in favor of the group treated with mesalazine. The duration of abdominal pain due to diverticolitis was also shorter in patients of group M (p=0.0002), while the incidence of major complications and side effects was comparable in the two groups. In conclusion, supplementary treatment with mesalazine in patients affected with MDC--at a follow-up limited to 48 months--proved to be well tolerated and effective in reducing the frequency of symptomatic relapses and microhemorrhagic phenomena and in reducing the duration of abdominal pain.

Ocular albinism: evidence for a defect in an intracellular signal transduction system

G protein-coupled receptors (GPCRs) participate in the most common signal transduction system at the plasma membrane. The wide distribution of heterotrimeric G proteins in the internal membranes suggests that a similar signalling mechanism might also be used at intracellular locations. We provide here structural evidence that the protein product of the ocular albinism type 1 gene (OA1), a pigment cell-specific integral membrane glycoprotein, represents a novel member of the GPCR superfamily and demonstrate that it binds heterotrimeric G proteins. Moreover, we show that OA1 is not found at the plasma membrane, being instead targeted to specialized intracellular organelles, the melanosomes. Our data suggest that OA1 represents the first example of an exclusively intracellular GPCR and support the hypothesis that GPCR-mediated signal transduction systems also operate at the internal membranes in mammalian cells.

[Efficacy of low dose mesalazine (5-ASA) in the treatment of acute inflammation and prevention of complications in patients with symptomatic diverticular disease. Preliminary results]

MATERIALS AND METHODS

To assess the efficacy of mesalazine in treating acute diverticulitis and preventing diverticular disease (DD) complication. 166 patients with symptomatic DD were randomly assigned to receive mesalazine Pentacol (400 mg b.i.d., orally; M group) or no additional treatment (controls; C group).

RESULTS

After a 12 months follow-up, 26 patients experienced a symptomatic relapse (8%M vs 27% C, p=0.003), with a higher rate in C group for the patients with a history of previous diverticulitis (p=0.006) and independently of the diverticular site (sigmoid p=0.041; colon and sigmoid p=0.044). Minor diverticular haemorrhages were less frequent in M group (p=0.016), with a significant difference only for the patients with sigmoid diverticula (p=0.023); abdominal pain persisted for a shorter time in the treated group (p=0.0015).

CONCLUSIONS

No significant difference was found between the two groups for the incidence of DD major complications.
