Review
BACKGROUND
Group B streptococcus or streptococcus Agalactia is a gram positive beta hemolytic bacteria which is the main factor in neonatal infections. This study aimed at determining the prevalence of GBS in world and clarifying the rate of this infection in Islamic and non-Islamic countries.
METHODS
We performed a systematic search by using different databases including Medline, Scopus, Science Direct, Psycho-Info ProQuest and Web of Science published up to Feb 2019. We undertook meta-analysis to obtain the pooled estimate of prevalence of GBS colonization in Islamic and non-Islamic countries.
RESULTS
Among 3324 papers searched, we identified 245 full texts of prevalence of GBS in pregnancy; 131 were included in final analysis. The estimated mean prevalence of maternal GBS colonization was 15.5% (CI:95% (14.2-17)) worldwide; which was 14% (CI:95% (11-16.8)) in Islamic and 16.3% (CI:95% (14.6-18.1)) in non-Islamic countries and was statistically significant. Moreover, with regards to sampling area, prevalence of GBS colonization was 11.1 in vagina and 18.1 in vagina-rectum.
CONCLUSION
Frequent washing of perineum based on religious instructions in Islamic countries can diminish the rate of GBS colonization in pregnant women.

Journal of Clinical Nursing May 2023To investigate the effect of tissue adhesives on perineal wound healing and pain relief in women with perineal trauma during childbirth. (Meta-Analysis)
Meta-Analysis Review
AIMS AND OBJECTIVES
To investigate the effect of tissue adhesives on perineal wound healing and pain relief in women with perineal trauma during childbirth.
BACKGROUND
Due to the high incidence and severe consequences of perineal trauma during childbirth, tissue adhesives are recommended as an alternative to conventional sutures to repair perineal trauma. Although many original studies have explored the effect of tissue adhesives on perineal wound healing and pain relief in women with perineal trauma during childbirth, these studies have differed in participants, interventions and outcomes. Therefore, the effect of tissue adhesives on wound healing and pain relief in perineal trauma during childbirth is inconclusive.
DESIGN
A systematic review and meta-analysis based on PRISMA 2020.
METHODS
A systematic and comprehensive literature search was conducted. Eight electronic databases, three clinical trial registers, and grey literature were searched from inception to 28th April 2021 and reference lists were also retrieved. Randomised controlled trials (RCTs) involving women with first- or second-degree perineal lacerations or women who underwent episiotomy were included. The intervention was the use of tissue adhesives alone or in combination with sutures. For the outcome indicators of perineal wound healing and pain relief, subgroup analyses based on the extent of perineal trauma and measurement time points were conducted, respectively.
RESULTS
A total of 14 RCTs involving 2264 participants were included in this research. The results indicated that for first-degree lacerations, the incidence of wound complications was significantly higher in the tissue adhesives group. In contrast, for episiotomy, the effect of the combination of tissue adhesives and sutures was comparable to that of sutures exclusively. The pooled results revealed that tissue adhesives exerted a positive effect on relieving immediate and short-term perineal pain, but no significant difference was found in the effect of long-term pain relief. Moreover, this review also supported the effect of tissue adhesives in shortening intraoperative repair time and improving clinician-maternal satisfaction.
CONCLUSIONS
The existing evidence illustrates that tissue adhesives effectively promote perineal wound healing and relieve immediate and short-term pain. However, for first-degree lacerations, the increased occurrence of wound complications must be prudently considered when applying tissue adhesives alone, whereas, for episiotomy, the combination of tissue adhesives and sutures may be a promising repair alternative. Future studies are encouraged to adopt long-term effect, adverse effect, and cost-effect analysis as important outcome indicators to comprehensively validate the applicability and generalisability of tissue adhesives.
RELEVANCE TO CLINICAL PRACTICE
For first-degree perineal lacerations, we do not recommend using tissue adhesives alone to repair the wound, given the increased wound complications. While for episiotomy, the combination of tissue adhesives and sutures may be a promising alternative to the use of sutures exclusively. Additionally, the adverse effect and long-term effect of using tissue adhesives alone to repair perineal trauma should be further clarified.

Meta-Analysis Review
OBJECTIVE
This study aimed to compare the prognostic accuracy of intrapartum transperineal ultrasound measures of fetal descent before operative vaginal birth in predicting complicated or failed procedures.
DATA SOURCES
We performed a predefined systematic search in Medline, Embase, CINAHL, and Scopus from inception to June 10, 2022.
STUDY ELIGIBILITY CRITERIA
We included studies assessing the following intrapartum transperineal ultrasound measures before operative vaginal birth to predict procedure outcome: angle of progression, head direction, head-perineum distance, head-symphysis distance, midline angle, and/or progression distance.
METHODS
Study quality was assessed using the Quality Assessment of Diagnostic Accuracy Studies-2 tool. Bivariate meta-analysis was used to pool sensitivities and specificities into summary receiver operating characteristic curves for each intrapartum transperineal ultrasound measure. Subgroup analyses were performed for measures taken at rest vs with pushing and prediction of failed vs complicated operative vaginal birth.
RESULTS
Overall, 16 studies involving 2848 women undergoing attempted operative vaginal birth were included. The prognostic accuracy of intrapartum transperineal ultrasound measures taken at rest to predict failed or complicated operative vaginal birth was high for angle of progression (area under the receiver operating characteristic curve, 0.891; 9 studies) and progression distance (area under the receiver operating characteristic curve, 0.901; 3 studies), moderate for head direction (area under the receiver operating characteristic curve, 0.791; 6 studies) and head-perineum distance (area under the receiver operating characteristic curve, 0.747; 8 studies), and fair for midline angle (area under the receiver operating characteristic curve, 0.642; 4 studies). There was no study with sufficient data to assess head-symphysis distance. Subgroup analysis showed that measures taken with pushing tended to have a higher area under the receiver operating characteristic curve for angle of progression (0.927; 4 studies), progression distance (0.930; 2 studies), and midline angle (0.903; 3 studies), with a similar area under the receiver operating characteristic curve for head direction (0.802; 4 studies). The prediction of failed vs complicated operative vaginal birth tended to be less accurate for angle of progression (0.837 [4 studies] vs 0.907 [6 studies]) and head direction (0.745 [3 studies] vs 0.810 [5 studies]), predominantly because of lower specificity, and was more accurate for head-perineum distance (0.812 [6 studies] vs 0.687 [2 studies]).
CONCLUSION
Angle of progression, progression distance, and midline angle measured with pushing demonstrated the highest prognostic accuracy in predicting complicated or failed operative vaginal birth. Overall, the measurements seem to perform better with pushing than at rest.

Meta-Analysis
BACKGROUND
Negative maternal outcomes such as perineal trauma and related perineal pain may cause both long-and short- term morbidities. Hands on and hands off/poised technique are two kinds of techniques to protect perineum during the second-stage of labor. Hands on technique has been the routine midwifery practice for a long time; nevertheless, the effects of hands on technique on protecting perineum has been doubted. Hands off/poised as a promising technique seems prevalent in clinical practice. However, there is no consensus on use of hands off/poised technique and hands on technique. The effects of these techniques on maternal outcomes have not been fully investigated.
OBJECTIVE
To evaluate the effects of hands on hands off/poised technique on maternal outcomes during the second-stage of labor.
DESIGN
Systematic review and meta-analysis of relevant quantitative studies.
DATA SOURCES
Seven databases: PubMed, EMBASE, The Cochrane Library, CINAHL, WanFang Data, China National Knowledge Infrastructure (CKNI), SinoMed were systematically searched from inception to July 23,2018 for relevant quantitative studies comparing the effects of hands on and hands off/poised technique on maternal outcomes.
REVIEW METHODS
Quantitative studies were retrieved for relevant studies. Two reviewers independently screened the studies, evaluated the methodological quality using JBI appraisal checklist tools and extracted the data. The included studies were divided into two groups for analysis according to study types.
RESULTS
Nine RCTs with a total of 7112 participants and eight non-RCTs with 37,786 participants were included for meta-analysis. Based on the results from RCTs, this study did not find difference between hands on and hands off/poised technique regarding the risk of 2nd perineal tears, 3rd /4th degree perineal tears, duration of second-stage labor and incidence of postpartum hemorrhage (PPH>500 ml). The results from 9 non-RCTs were similar with that of RCTs, except for showing less 2nd degree perineal tears in hands off/poised technique than in hands on technique.
CONCLUSION
Evidence in the present study indicated that hands off/poised technique may be a promising delivery technique to maintain intact perineum, and reduce perineal pain and episiotomy use among women with low-risk pregnancy undergoing vaginal delivery. In addition, hands off/poised technique might be safe to use as it did not increase the risk of severe perineal trauma, postpartum hemorrhage, and longer duration of second-stage labor when compared with hands on technique. More studies with stringent study design, especially large randomized controlled trial, should be conducted before strong recommendation of the hands off/poised technique.

Review
Patients suffering from hematological malignancies are at increased risk of Fournier's gangrene (FG) due to immunosuppression caused by the disease itself or by disease-related treatments. A systematic review of PubMed, ISI Web of Knowledge, and Scopus databases was performed in June 2021. We included full papers that met the following criteria: original research, human studies, and describing clinical presentation, treatment, and outcomes of FG in patients with oncohematological diseases. We identified 35 papers published from 1983 to 2021 involving 44 patients (34 males, 8 females) aged between 4 days and 83 years. The most common malignant hematological disorders were acute myeloid leukemia ( 21) and acute lymphocytic leukemia ( 9). In 10 patients FG represented the first presentation of hematological malignancy. Scrotum (= 27) and perineum ( 11) were the sites most commonly involved. ( 21) and ( 6) were the most commonly isolated microorganisms. Surgery was performed in 39 patients. Vacuum-assisted closure and hyperbaric oxygen therapy were adopted in 4 and in 3 patients, respectively. Recovery was achieved in 30 patients. FG-related mortality was observed in 11 patients. FG should be carefully considered in patients with oncohematological diseases.

Review
BACKGROUND
This is a paucity of data regarding plastic surgeons' opinions on robotic-assisted surgery (RAS). We developed a questionnaire aimed to survey plastic surgeons regarding training in robotics, concerns about widespread implementation, and new research directions.
METHODS
A survey was created using Google Forms and sent to practicing plastic surgeons and trainees. Responses regarding desired conference proceedings about robotics, robotic residency training, and perceived barriers to implementation were elicited. Survey responses were utilized to direct a systematic review on RAS in plastic surgery.
RESULTS
The survey received 184 responses (20.4%; 184/900). The majority (92.8%) of respondents were/are plastic surgery residents, with the most common fellowships being microsurgery (39.2%). Overall, 89.7% of respondents support some integration of robotics in the future of plastic surgery, particularly in pelvic/perineum reconstruction (56.4%), abdominal reconstruction (46.5%), microsurgery (43.6%), and supermicrosurgery (44.2%). Many respondents (66.1%) report never using a robot in their careers. Respondents expressed notable barriers to widespread robotic implementation, with cost (73.0%) serving as the greatest obstacle. A total of 10 studies (pelvic/perineum = 3; abdominal = 3; microsurgery = 4) were included after full-text review.
CONCLUSIONS
Evidence from our survey and review supports the growing interest and utility of RAS within the plastic and reconstructive surgery (PRS) and mirrors the established trend in other surgical subspecialties. Cost analyses will prove critical to implementing RAS within PRS. With validated benefits, plastic surgery programs can begin creating dedicated curricula for RAS.

Review
PURPOSE
Necrotizing fasciitis (NF) is a life-threatening infection that involves spreading necrosis of the subcutaneous tissue and fascia that affects the extremities, abdominal wall, and perineum. Primary infection of the breast is a rare occurrence. Shah et al described the first case of primary breast NF and recommended radical "pseudotumor" excision and delayed skin closure months after resolution. Numerous other cases reported were successfully managed with different strategies. We aimed to summarize management options for primary breast NF through a systematic review of the literature.
METHODS
A systematic review of English literature was performed using PubMed. A total of 58 abstracts were reviewed. Data were abstracted from 25 cases that met inclusion criteria.
RESULTS
A total of 25 cases of primary NF of the breast without an inciting event were found within the literature. Common initial operations included total mastectomy (36.0%), excisional debridement (32.0%), and partial mastectomy (12.0%). A total or radical mastectomy was completed for definitive source control in 13 (52.0%) cases. A total of 18 cases underwent reconstruction. Split-thickness skin grafts (44.4%) and delayed primary closures (33.3%) were the most common methods of reconstruction.
CONCLUSION
Majority of cases with primary breast NF are managed with a total mastectomy to gain source control. Reconstruction using split-thickness skin grafts was most common. Other options included delayed primary closure, full thickness skin grafts, local tissue rearrangement, and pedicle flap reconstruction. Reconstruction should be patient dependent, but the whole arsenal of the reconstructive ladder may be used.

Review
OBJECTIVE
Obstetrical anal sphincter injury describes a severe injury to the perineum and perianal muscles after birth. Obstetrical anal sphincter injury occurs in approximately 4.4% of vaginal births in the United States; however, racial and ethnic inequities in the incidence of obstetrical anal sphincter injury have been shown in several high-income countries. Specifically, an increased risk of obstetrical anal sphincter injury in individuals who identify as Asian vs those who identify as White has been documented among residents of the United States, Australia, Canada, Western Europe, and the Scandinavian countries. The high rates of obstetrical anal sphincter injury among the Asian diaspora in these countries are higher than obstetrical anal sphincter injury rates reported among Asian populations residing in Asia. A systematic review and meta-analysis of studies in high-income, non-Asian countries was conducted to further evaluate this relationship.
DATA SOURCES
MEDLINE, Ovid, Embase, EmCare, and the Cochrane databases were searched from inception to March 2023 for original research studies.
STUDY ELIGIBILITY CRITERIA
Observational studies using keywords and controlled vocabulary terms related to race, ethnicity and obstetrical anal sphincter injury. All observational studies, including cross-sectional, case-control, and cohort were included. 2 reviewers followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and the Meta-analysis of Observational Studies in Epidemiology recommendations.
METHODS
Meta-analysis was performed using RevMan (version 5.4; Cochrane Collaboration, London, United Kingdom) for dichotomous data using the random effects model and the odds ratios as effect measures with 95% confidence intervals. Subgroup analysis was performed among Asian subgroups. The risk of bias was assessed using the Joanna Briggs Institute Critical Appraisal tools. Meta-regression was used to determine sources of between-study heterogeneity.
RESULTS
A total of 27 studies conducted in 7 countries met the inclusion criteria encompassing 2,337,803 individuals. The pooled incidence of obstetrical anal sphincter injury was higher among Asian individuals than White individuals (pooled odds ratio, 1.64; 95% confidence interval, 1.48-1.80). Subgroup analyses showed that obstetrical anal sphincter injury rates were highest among South Asians and among population-based vs hospital-based studies. Meta-regression showed that moderate heterogeneity remained even after accounting for differences in studies by types of Asian subgroups included, study year, mode of delivery included, and study setting.
CONCLUSION
Obstetrical anal sphincter injury is more frequent among Asian versus white birthing individuals in multiple high-income, non-Asian countries. Qualitative and quantitative research to elucidate underlying causal mechanisms responsible for this relationship are warranted.

Meta-Analysis
INTRODUCTION
Perineal pressure associated with bicycle riding is the cause of several genitourinary pathologies, most notably Alcock's syndrome and subsequent perineal numbness. The possible link between cycling-induced perineal numbness and erectile dysfunction makes the development of strategies for perineal protection in bicycle users critical.
OBJECTIVE
To assess the effectiveness of strategies for reducing the impact of cycling on the perineum in healthy males.
METHODS
We have conducted a systematic review and a meta-analysis of studies examining various means of reducing the impact of cycling on the perineum under the PRISMA guidelines.
RESULTS
Out of 2217 screened studies, 22 met our inclusion criteria, and 6 qualified for meta-analysis. The strategies included various designs of saddles, changes in the cycling position, seat shock absorber, shorts with different padding, using the recumbent bike. Using the no-nose saddle and recumbent bike resulted in a significant reduction of perineal pressure and higher penile oxygen pressure compared with a standard saddle. Indirect evidence supports the protective effect of standing on the pedals every few minutes during cycling. More evidence is needed to support-or dismiss-other strategies.
CONCLUSIONS
Current evidence supports the use of no-nose saddles as a mean to reduce the negative impact of cycling on the perineum in healthy males at the cost of worse stability and increase of posterior seat pressure. Standing on the pedals every ten minutes might be an effective and potentially widely applicable strategy. The use of a recumbent bike appears to protect the perineum, but several concerns prevent its widespread use.

BACKGROUND
Necrotising soft tissue infections (NSTI) are destructive and often life-threatening infections of the skin and soft tissue, necessitating prompt recognition and aggressive medical and surgical treatment. After debridement, the aim of surgical closure and reconstruction is to minimize disability and optimize appearance. Although skin grafting may fulfil this role, techniques higher on the reconstructive ladder, including local, regional and free flaps, are sometimes undertaken. This systematic review sought to determine the circumstances when this is true, which flaps were most commonly employed, and for which anatomical areas.
METHODS
A systematic review of the literature was conducted utilising electronic databases (Medline, Embase, Cochrane Library). Full text studies of flaps used for the management of NSTI's (including Necrotising Fasciitis and Fournier Gangrene) were included. The web-based program 'Covidence' facilitated storage of references and data management. Data obtained in the search included reference details (journal, date and title), the study design, the purpose of the study, the study findings, number of patients with NSTI included, the anatomical areas of NSTI involved, the types of flaps used, and the complication rate.
RESULTS
After screening 4555 references, 501 full text manuscripts were assessed for eligibility after duplicates and irrelevant studies were excluded. 230 full text manuscripts discussed the use of 888 flap closures in the context of NSTI in 733 patients; the majority of these were case series published in the last 20 years in a large variety of journals. Reconstruction of the perineum following Fournier's gangrene accounted for the majority of the reported flaps (58.6%). Free flaps were used infrequently (8%), whereas loco-regional muscle flaps (18%) and loco-regional fasciocutaneous flaps (71%) were employed more often. The reported rate of partial or complete flap loss was 3.3%.
CONCLUSION
Complex skin and soft tissue defects from NSTIs, not amenable to skin grafting, can be more effectively and durably covered using a spectrum of flaps. This systematic review highlights the important contribution that the plastic surgeon makes as an integral member of multidisciplinary teams managing these patients.
