An Algorithmic Approach to Dual-System Venous Drainage for DIEP Flap Breast Reconstruction

BACKGROUND

Few studies compared the use of the deep venous system alone versus combined superficial and deep venous drainage in DIEP flaps. The objective of this study is to compare DIEP flap breast reconstruction using either the deep venous system alone versus dual-system venous drainage and to propose an algorithm for flap design and orientation and veins selection to facilitate consistent use of dual-system venous drainage.

METHODS

Patients undergoing DIEP flap breast reconstruction between March 2017 and April 2021 were retrospectively reviewed. Flaps were divided into two groups: deep venous system only (Group 1) or dual-system (Group 2). Outcomes included takeback to the operating room (OR), flap loss and thrombosis and operative time.

RESULTS

A total of 244 DIEP flaps in 162 patients met inclusion criteria. A total of 130 flaps were included in Group 1 (53.3%) and 114 flaps were included in Group 2 (46.7%). Sixteen flaps (6.6%) required immediate takeback to the OR and takeback rates were not significantly different between groups (p=0.606). Flap loss rate was significantly higher in Group 1: 2.5% vs Group 2: 0%; p=0.031. Flap thrombosis occurred in 8 flaps (3.3%) and tended to occur more frequently in Group 1 but this finding did not reach significance (Group 1: 5.4% vs Group 2: 0.9%; p=0.071).

CONCLUSIONS

The use of dual-system venous drainage in DIEP flap breast reconstruction decreases the rate of flap loss. Our algorithm can be used to guide selection of flap laterality, rotation, and veins and recipient vessels to facilitate routine use of dual-system venous drainage.

Barriers to sustainable health research leadership in the Global South: Time for a Grand Bargain on localization of research leadership?

BACKGROUND

Strong Global South (GS) health research leadership, itself both dependent on and a requisite for strong health research systems, is essential to generate locally relevant research and ensure that evidence is translated into policy and practice. Strong GS health research systems and leadership are important for health development and in turn for strong health systems. However, many GS countries struggle to produce research and to improve performance on widely used research metrics measuring productivity and reflecting leadership. Drawing on literature from a rapid review, this viewpoint paper considers the barriers to GS health research leadership and proposes strategies to address these challenges.

FINDINGS

GS researchers and institutions face numerous barriers that undermine health research leadership potential. Barriers internal to the GS include researcher-level barriers such as insufficient mentorship, limited financial incentives and time constraints. Institutional barriers include limited availability of resources, restrictive and poorly developed research infrastructures, weak collaboration and obstructive policies and procedures. Structural barriers include political will, politicization of research and political instability. External barriers relate to the nature and extent of Global North (GN) activities and systems and include allocation and distribution of funding and resources, characteristics and focus of GN-GS research collaborations, and publication and information dissemination challenges.

CONCLUSIONS

Strengthening GS health research leadership requires acknowledgement of the many barriers, and adoption of mitigating measures by a range of actors at the institutional, national, regional and global levels. Particularly important are leadership capacity development integrating researcher, institutional and systems initiatives; new GN-GS partnership models emphasizing capacity exchange and shared leadership; supporting GS research communities to set, own and drive their research agendas; addressing biases against GS researchers; ensuring that GS institutions address their internal challenges; enhancing South-South collaborations; diversifying research funding flow to the GS; and learning from models that work. The time has come for a firm commitment to improving localization of research leadership, supported by adequate funding flow, to ensure strong and sustainable research systems and leadership in and from the GS. Just as the humanitarian donor and aid community adopted the Grand Bargain commitment to improve funding flow through local and national responders in times of crisis, we strongly urge the global health research community to adopt a Grand Bargain for research leadership.

The health of internally displaced people in Syria: are current systems fit for purpose?

•

At 6.7 million, Syria has the largest number of internally displaced people globally.

•

Health of IDPs in Syria is often not disaggregated from that of other populations.

•

IDPs face intersecting vulnerabilities and social determinants which impact health.

•

Syria's fragmented health system results in different system responses for IDPs.

•

The evidence base on IDP health in Syria is weak and requires strengthening.

Introduction: Syria has the largest number of internally displaced people (IDPs) globally with 6.7 million forced from their homes since the uprising erupted in 2011. Most face multiple intersecting vulnerabilities with adverse health impacts. We explore the key health concerns among IDPs, how the various health systems in Syria have responded to the dynamic health needs of IDPs and what modalities have been used by humanitarian actors to address these needs. Methods: We undertook a scoping review of academic and grey literature for available evidence regarding the health of IDPs in Syria. We then organised an online workshop in November 2021 with around 30 participants who represent local, regional, and international organisations and who have relevant expertise. The discussion focused on how the health systems in Syria's various territories have responded to the health needs of IDPs, what this means to the structure and dynamics of these health systems and their intended outcomes and responsiveness. Findings: These emphasised the weak evidence base around IDP health in Syria, particularly in certain geographical areas. Workshop participants explored the applicability of the term IDP in the Syrian context given the fragmented health system and its impact on IDPs, the importance of considering co-determinants (beyond forced displacement) on the health of IDPs and taking a transectoral, community led approach to identify and respond to needs. Conclusion: This manuscript presents some of the current issues with regards to IDP health in Syria, however, there remain numerous unknowns, both for the health of IDP as well as non-IDP populations. We hope that it will be the foundation for further discussions on practical steps relating to research, analysis and interventions which can support health system responses for IDPs in Syria.

Conflict-related health research in Syria, 2011-2019: a scoping review for The Lancet - AUB Commission on Syria

BACKGROUND

The volume of health-related publications on Syria has increased considerably over the course of the conflict compared with the pre-war period. This increase is largely attributed to commentaries, news reports and editorials rather than research publications. This paper seeks to characterise the conflict-related population and humanitarian health and health systems research focused inside Syria and published over the course of the Syrian conflict.

METHODS

As part of a broader scoping review covering English, Arabic and French literature on health and Syria published from 01 January 2011 to 31 December 2019 and indexed in seven citation databases (PubMed, Medline (OVID), CINAHL Complete, Global Health, EMBASE, Web of Science, Scopus), we analyzed conflict-related research papers focused on health issues inside Syria and on Syrians or residents of Syria. We classified research articles based on the major thematic areas studied. We abstracted bibliometric information, study characteristics, research focus, funding statements and key limitations and challenges of conducting research as described by the study authors. To gain additional insights, we examined, separately, non-research publications reporting field and operational activities as well as personal reflections and narrative accounts of first-hand experiences inside Syria.

RESULTS

Of 2073 papers identified in the scoping review, 710 (34%) exclusively focus on health issues of Syrians or residents inside Syria, of which 350 (49%) are conflict-related, including 89 (25%) research papers. Annual volume of research increased over time, from one publication in 2013 to 26 publications in 2018 and 29 in 2019. Damascus was the most frequently studied governorate (n = 33), followed by Aleppo (n = 25). Papers used a wide range of research methodologies, predominantly quantitative (n = 68). The country of institutional affiliation(s) of first and last authors are predominantly Syria (n = 30, 21 respectively), the United States (n = 25, 19 respectively) or the United Kingdom (n = 12, 10 respectively). The majority of authors had academic institutional affiliations. The most frequently examined themes were health status, the health system and humanitarian assistance, response or needs (n = 38, 34, 26 respectively). Authors described a range of contextual, methodological and administrative challenges in conducting research on health inside Syria. Thirty-one publications presented field and operational activities and eight publications were reflections or first-hand personal accounts of experiences inside Syria.

CONCLUSIONS

Despite a growing volume of research publications examining population and humanitarian health and health systems issues inside conflict-ravaged Syria, there are considerable geographic and thematic gaps, including limited research on several key pillars of the health system such as governance, financing and medical products; issues such as injury epidemiology and non-communicable disease burden; the situation in the north-east and south of Syria; and besieged areas and populations. Recognising the myriad of complexities of researching active conflict settings, it is essential that research in/on Syria continues, in order to build the evidence base, understand critical health issues, identify knowledge gaps and inform the research agenda to address the needs of the people of Syria following a decade of conflict.

Auricular pseudocysts: a systematic review of the literature

BACKGROUND

Auricular pseudocysts are benign fluid accumulations of the ear of uncertain etiology. Little is known about the optimal modality to successfully treat these lesions. No systematic review addressing auricular pseudocysts have been published to date.

OBJECTIVES

The aim of this study is to summarize all the published data regarding diagnostic and therapeutic challenges of auricular pseudocysts.

METHODS

On May 28, 2020, a systematic search of Medline, Embase, and Cochrane databases was conducted. All the studies describing treatment of auricular pseudocysts, procedure description, outcome, and follow-up period were included in this review.

RESULTS

After full-text article review, 74 articles were included, representing a total of 1,011 lesions. The commonly used treatments for auricular pseudocysts were deroofing (493 lesions), aspiration (284 lesions), incision and drainage (171 lesions), intralesional steroids (53 lesions), and observation (10 lesions). The highest cure rate was found with the deroofing procedure (97.2%) followed by incision and drainage (95.9%). The mean follow-up period was 6.7 months.

CONCLUSION

Surgical procedures (anterior deroofing or incision and drainage) showed the highest cure rates and should be considered as first-line treatment for auricular pseudocysts. Future adequately designed randomized controlled trials are warranted to compare the efficacy of the techniques described.

Policies on return and reintegration of displaced healthcare workers towards rebuilding conflict-affected health systems: a review for The Lancet-AUB Commission on Syria

Background

War and armed conflicts severely disrupt all health system components, including the healthcare workforce. Although data is limited on the scale of health care worker (HCW) displacement in conflict zones, it is widely acknowledged that conflict conditions result in the displacement of a significant portion of qualified HCWs from their country of origin. While voluntary HCW return is integral to health system rebuilding in conflict-affected and post-conflict settings, there has been little exploration of the nature of national or international policies which encourage HCW return and reintegration to their home countries in the post-conflict period.

Methods

We conducted a systematic review to identify policies and policy recommendations intended to facilitate the return of displaced HCWs to their home countries and acknowledge their contribution to rebuilding the post-conflict health system. We searched three bibliographic databases and a range of organisational and national health agency websites to identify peer-reviewed articles and grey literature published in English or Arabic between 1 January 1990 to 24 January 2021, and extracted relevant information. We classified policies and policy recommendations using an adapted version of the UNHCR 4Rs Framework.

Results

We identified nine peer-review articles and four grey literature reports that fit our inclusion criteria, all of which were published in English. These covered issues of repatriation (n = 3), reintegration (n = 2), health system rehabilitation and reconstruction (n = 2); six documents covered several of these themes. Information was available for nine conflict contexts: Afghanistan, Iraq, Kosovo, Lebanon, Namibia, Northern Uganda, South Sudan, Timor Leste, and Zimbabwe. Findings demonstrate that health system rebuilding and rehabilitation serve as precursors and reinforcers of the successful return, repatriation, and reintegration of displaced HCWs.

Conclusions

Despite the significant numbers of HCWs displaced by conflict, this study identified few specific policies and limited information explicitly focused on the repatriation and reintegration of such workers to their home country in the post-conflict period. Additional research is needed to understand the particular barriers faced by conflict-displaced HCWs in returning to their home country. Conflict-affected and post-conflict states should develop policies and initiatives that address factors within and beyond the health sector to encourage displaced HCW return and provide sustainable reintegration solutions for those who return to post-conflict health systems.

'We need someone to deliver our voices': reflections from conducting remote qualitative research in Syria

The need to generate evidence in spaces considered insecure and inhabited by potentially extremely vulnerable individuals (e.g. conflict-affected people who may not have means to move) has led researchers to study conflict-affected settings remotely. Increased attention to remote research approaches from social scientists, due to COVID-19-related travel restrictions, is sparking interest on appropriate methods and tools. Drawing on several years' experience of remotely conducting qualitative research in Syria, we discuss challenges and approaches to conducting more inclusive, participatory, and meaningful research from a distance. The logistics, ethics, and politics of conducting research remotely are symptomatic of broader challenges in relation to the decolonisation of global and humanitarian health research. Key to the success of remote approaches is the quality of the relationships researchers need to be able to develop with study participants without face-to-face interactions and with limited engagement 'in the field'. Particularly given overdue efforts to decolonise research institutions and methods, lead researchers should have a meaningful connection with the area in which they are conducting research. This is critical both to reduce chances that it will be extractive and exploitative and additionally for the quality of interpretation.

An unusual tell sign of botulinum toxin injection in patients with facial flushing: incorporating a new questionnaire in the evaluation of botulinum toxin patients

Lately it has been established that intra-dermal botulinum toxin is also effective in treating many dermatological conditions including refractory erythematous-telangiectatic rosacea, post - menopausal facial flushing and other similar conditions.However, the desired effect of treating the reddening in patients suffering from facial flushing can become an undesirable and embarrassing side effect when these same patients present to the clinic for esthetic concerns such as upper face rhytids. In this case, intramuscular botulinum toxin injections used for wrinkles treatment will also secondarily treat the facial reddening in their localized skin diffusion zones and result in embarrassing white patches all over the face. The patchy appearance following botulinum toxin injections for esthetic purposes could be bothersome for some patients and could be a tell-tale sign of botulinum toxin injections.

Health-related articles on Syria before and after the start of armed conflict: a scoping review for The Lancet-American University of Beirut Commission on Syria

Introduction

Armed conflict may influence the size and scope of research in Arab countries. We aimed to assess the impact of the 2011 Syrian conflict on health articles about Syria published in indexed journals.

Methods

We conducted a scoping review on Syrian health-related articles using seven electronic databases. We included clinical, biomedical, public health, or health system topics published between 1991 and 2017. We excluded animal studies and studies conducted on Syrian refugees. We used descriptive and social network analyses to assess the differences in rates, types, topics of articles, and authorship before and after 2011, the start of the Syrian conflict.

Results

Of 1138 articles, 826 (72.6%) were published after 2011. Articles published after 2011 were less likely to be primary research; had a greater proportion reporting on mental health (4.6% vs. 10.0%), accidents and injuries (2.3% vs. 18.8%), and conflict and health (1.7% vs. 7.8%) (all p < 0.05); and a lower proportion reporting on child and maternal health (8.1 to 3.6%, p = 0.019). The proportion of research articles reporting no funding increased from 1.1 to 14.6% (p < 0.01). While international collaborations increased over time, the number of articles with no authors affiliated to Syrian institutions overtook those with at least one author affiliation to a Syrian institution for the first time in 2015.

Conclusion

To our knowledge, this is the first study to examine the impact of armed conflict on health scholarship in Syria. The Syrian conflict was associated with a change in the rates, types, and topics of the health-related articles, and authors’ affiliations. Our findings have implications for the prioritization of research funding, development of inclusive research collaborations, and promoting the ethics of conducting research in complex humanitarian settings.

Acquired ungual fibrokeratoma: a systematic review of the literature

BACKGROUND

Acquired ungual fibrokeratomas (AUFKs) are benign recurrent fibrokeratotic tumors of the nail unit of uncertain etiology. Little is known about the optimal modality to successfully treat these lesions. No systematic review addressing ungual fibrokeratomas has been published to date.

OBJECTIVES

The aim of this study is to summarize all the published data regarding diagnostic and therapeutic challenges of AUFKs.

METHODS

On August 9, 2019, a systematic search of Medline and Cochrane databases was conducted. All the studies describing the treatment of ungual fibrokeratomas, procedure description, pathological findings, outcome, and follow-up period were included in this review.

RESULTS

After full-text article review, 103 articles were included, representing a total of 78 lesions. The commonly used treatments for fibrokeratomas were complete tumor resection (90.5%), shave excision (8.3%), and cryotherapy (1.2%). Complete surgical excision yielded the highest cure rate among all treatment modalities (90.8%) compared to partial surgical excision (28.6%) and cryotherapy (0%). The mean follow-up period was 12.1 months (1-144).

CONCLUSION

Complete surgical removal preserving the matrix showed the highest cure rates and should be considered as first-line treatment for AUFKs. Future adequately designed randomized control trials are warranted to compare different treatment modalities.

Quilting Sutures in Rhytidectomy: A Systematic Review of the Literature

BACKGROUND

Different technical variations exist for the utilization of quilting sutures (QS) in rhytidectomy. No systematic review or meta-analysis of the studies describing the use of QS in facelifts has been published to date to the authors' knowledge.

OBJECTIVES

The objective of this study was to summarize all the published data regarding the utilization of QS in rhytidectomy, compare QS techniques, and evaluate their effect on postoperative complications.

METHODS

On April 1, 2019, a systematic search of the Medline, Embase, and Cochrane databases was conducted. All the studies describing the usage of QS in facelifts were included in this review. Studies reporting hematoma rate in a QS group and a control group were included in the meta-analysis part of this study.

RESULTS

The initial search of the databases yielded 93 results. Four trials were included in the systematic review and 2 were included in the meta-analysis. The total number of included patients with QS was 527. Two studies employed internal QS and the remaining studies utilized external QS. The meta-analysis found a lower rate of hematoma in the QS group (relative risk, 0.02; 95% confidence interval = 0.00-0.13; P < 0.0001).

CONCLUSIONS

QS can be applied either internally or externally and are very effective in reducing hematomas after facelifts. QS could be a great asset in facelifts but should be utilized with caution because additional work is needed to confirm their safety and efficacy.

Experiences of healthcare workers displaced by conflict: lessons from past conflicts and implications

Background

Conflicts cause mass displacement, including of healthcare workers (HCWs). Understanding experiences of HCWs over the displacement trajectory, from push factors out of conflict zones, to barriers and facilitators in transit and host countries, is key to developing support mechanisms and informing policy discussions regarding return and reintegration.

Methodology

We systematically reviewed 6 academic databases and grey literature using combined search terms for HCWs, displacement, conflict, and experiences to identify English-language literature documenting personal or professional experiences of HCWs displaced by conflict, published between 1945 to 2020. Open coding and thematic analysis were used to identify emerging themes. Quality appraisal was conducted.

Results

25 publications from academic journals, snowballed references, and grey literature from 10 geographical contexts and various types of HCW met inclusion criteria, many from conflicts in the Middle-East. 5 themes emerged: Conflict drives displacement: HCWs fled due to direct violence and deteriorating working conditions caused by increased workload, depleting resources, workforce attrition and attacks on healthcare. Giving back: Refugee HCWs were determined to continue working but had to do so informally or by working with humanitarian agencies. Personal and professional integration in host countries: refugee HCWs overcame barriers to relicense after which they reported disadvantage in job applications due to professional gaps and discrimination; many ended up working under-qualified jobs. Psychological toll on HCWs was pronounced. Prospects on return: HCWs desired to return to their home countries but feared political instability and violence.

Conclusions

Policies which support HCW retention during conflict, integration into host health systems, and encourage return post-conflict must be implemented. Further research is required to understand the individual and systemic support mechanisms required.

Key messages

Displaced HCWs experience many personal and professional challenges. Policies that support HCWs across the displacement trajectory and support return and post-conflict system rebuilding are required.

"The Evolution of Eyebrow Morphology: The Westmore Model Revisited"

BACKGROUND

The most widely recognized eyebrow model was described by Westmore in 1974. With the rapidly changing concept of beauty, an accurate up-to-date model is needed.

METHODS

The Westmore model was tested on fashion models that were randomly selected from the covers of the 1965-1975 (group 1) and 2006-2016 (group 2) Vogue magazine. The eyebrows of fashion models, which represent the beauty ideals of these decades, were objectively measured and compared. We proposed a modified eyebrow model more adapted to the modern standards of beauty, applied it to group 2, and objectively compared it to the Westmore model. This new model was validated on a group of randomly selected Caucasian women.

RESULTS

Thirty women were included in each group. The medial edge of the eyebrow was better defined by the Westmore model in group 1 compared to group 2. The lateral edge of the eyebrow was better defined by the Westmore model in group 2. The peak of the eyebrow was not well defined by the Westmore model in both groups. The new model was more adapted than the Westmore model for both the medial edge and the peak of the eyebrow in group 2. It was also accurate in non-model Caucasian women.

CONCLUSION

Eyebrow morphology has evolved since the description of the Westmore model. Our model represents a simple way to accurately predict the eyebrow landmarks according to the modern ideals of beauty.

Health workers and the weaponisation of health care in Syria: a preliminary inquiry for The Lancet-American University of Beirut Commission on Syria

The conflict in Syria presents new and unprecedented challenges that undermine the principles and practice of medical neutrality in armed conflict. With direct and repeated targeting of health workers, health facilities, and ambulances, Syria has become the most dangerous place on earth for health-care providers. The weaponisation of health care-a strategy of using people's need for health care as a weapon against them by violently depriving them of it-has translated into hundreds of health workers killed, hundreds more incarcerated or tortured, and hundreds of health facilities deliberately and systematically attacked. Evidence shows use of this strategy on an unprecedented scale by the Syrian Government and allied forces, in what human rights organisations described as a war-crime strategy, although all parties seem to have committed violations. Attacks on health care have sparked a large-scale exodus of experienced health workers. Formidable challenges face health workers who have stayed behind, and with no health care a major factor in the flight of refugees, the effect extends well beyond Syria. The international community has left these violations of international humanitarian and human rights law largely unanswered, despite their enormous consequences. There have been repudiated denunciations, but little action on bringing the perpetrators to justice. This inadequate response challenges the foundation of medical neutrality needed to sustain the operations of global health and humanitarian agencies in situations of armed conflict. In this Health Policy, we analyse the situation of health workers facing such systematic and serious violations of international humanitarian law. We describe the tremendous pressures that health workers have been under and continue to endure, and the remarkable resilience and resourcefulness they have displayed in response to this crisis. We propose policy imperatives to protect and support health workers working in armed conflict zones.

Botulinum Toxin for Eyebrow Shaping: A Systematic Review

BACKGROUND

Currently, there is no standardized approach for eyebrow shaping with botulinum toxin, and controversies still exist regarding this subject.

OBJECTIVE

The objective of this systematic review is to summarize and compare all the published data regarding eyebrow shaping with botulinum toxin.

METHODS

On March 10, 2017, an online search of published articles in the Medline, Embase, and Cochrane databases were conducted. All articles that used objective measurements to quantify the eyebrow changes after botulinum toxin injection were included in this review.

RESULTS

Eleven studies were selected for inclusion with a total of 585 patients. All the included studies used onabotulinumtoxin A. Seven studies injected both the lateral and the medial eyebrow depressors, 2 studies injected the lateral depressors alone, and 2 studies injected the medial depressors alone. The highest elevation was observed in the lateral brow (0.4-4.8 mm). Bruising and headache were the most frequently reported complications, and only 5 cases of eyelid ptosis were noted.

CONCLUSION

Botulinum toxin injection for eyebrow shaping is a noninvasive, safe, and reproducible procedure. Eyebrow reshaping can be achieved by targeting different muscle groups. However, further randomized controlled trials are warranted.

Labia Majora Augmentation: A Systematic Review of the Literature

BACKGROUND

Currently, there is no standardized approach for labia majora augmentation and controversies still exist regarding this subject.

OBJECTIVES

This systematic review aimed to assess the evidence in the literature regarding labia majora augmentation.

METHODS

On November 20, 2016, we conducted an online search of published articles in the Medline, Embase, and Cochrane databases. All articles describing labia majora augmentation were included in this review.

RESULTS

Nine studies were selected for inclusion in the systematic review. Only 2 studies were prospective trials. The most commonly used technique was fat grafting with a total of 4 articles and 183 patients. The mean total injected fat volume ranged from 18 mL to 120 mL per session. Two articles described hyaluronic acid injection techniques. The total injected volume of hyaluronic acid ranged from 2 to 6 mL per session. Three articles used surgical techniques for labia majora augmentation. All included articles did not report any major or life-threatening complications. All techniques demonstrated high satisfaction rates.

CONCLUSIONS

Labia majora augmentation appears to be a safe, efficient technique with a high satisfaction rate and no reported major complications. However, further randomized controlled trials are warranted.

Does published research on non-communicable disease (NCD) in Arab countries reflect NCD disease burden?

Objectives

To review trends in non-communicable (NCD) research output in the Arab region, in terms of quantity and quality, study design, setting and focus. We also examined differences by time and place, and assessed gaps between research output and NCD burden.

Methods

A scoping review of a total of 3,776 NCD-related reports published between 2000 and 2013 was conducted for seven Arab countries. Countries were selected to represent diverse socio-economic development levels in the region: Regression analyses were used to assess trends in publications over time and by country. Research gaps were assessed by examining the degree of match between proportionate literature coverage of the four main NCDs (CVD, cancer, DM, and COPD) and cause-specific proportional mortality rates (PMR).

Results

The annual number of NCD publications rose nearly 5-fold during the study period, with higher income countries having the higher publication rates (per million populations) and the most rapid increases. The increase in the publication rate was particularly prominent for descriptive observational studies, while interventional studies and systematic reviews remained infrequent (slope coefficients = 13.484 and 0.883, respectively). Gap analysis showed a mismatch between cause-specific PMR burden and NCD research output, with a relative surplus of reports on cancer (pooled estimate +38.3%) and a relative deficit of reports on CVDs (pooled estimate -30.3%).

Conclusion

The widening disparity between higher and lower-income countries and the discordance between research output and disease burden call for the need for ongoing collaboration among Arab academic institutions, funding agencies and researchers to guide country-specific and regional research agendas, support and conduct.

Does the Addition of Progressive Tension Sutures to Drains Reduce Seroma Incidence After Abdominoplasty? A Systematic Review and Meta-Analysis

BACKGROUND

Progressive tension sutures (PTS) are commonly utilized to reduce postoperative seroma in abdominoplasty. However, current evidence regarding PTS in abdominoplasty is limited to small series and the findings of single institutions.

OBJECTIVES

The authors reviewed the available literature concerning the effects of PTS and drains on seroma formation following abdominoplasty, and summarized the different techniques that have been described to date.

METHODS

We conducted a systematic review of the Medline, Embase, and Cochrane databases. We identified randomized controlled trials (RCTs) and observational studies in which the numbers of patients who had postoperative seroma were indicated. We applied the Cochrane Collaboration's tool for assessing the risk of bias.

RESULTS

Seven studies were included (three RCTs and four retrospective studies). Patients who had PTS and drains following abdominoplasty had a significantly lower rate of postoperative seroma than those who had drains only. The mean surgical time difference between the two groups was 23 minutes. There was no difference in postoperative seroma rate in patients who had PTS and drains placed following abdominoplasty compared to those who had PTS only.

CONCLUSIONS

Addition of PTS to drains reduces the risk of postoperative seroma in standard abdominoplasty. More RCTs with larger sample sizes and better comparability are warranted to confirm with more confidence the impact of PTS in abdominoplasty.
