Abstract
Endometriosis is a common benign gynecological disease characterized by the presence of endometrial glands and stroma outside the uterus. It can be defined as endometrioma, superficial peritoneal endometriosis or deep infiltrating endometriosis (DIE) depending on the location and the depth of infiltration of the organs. In 5%-12% of cases, DIE affects the digestive tract, frequently involving the distal part of the sigmoid colon and rectum. Surgery is generally recommended in cases of obstructive symptoms and in cases with pain that is non-responsive to medical treatment. Selection of the most optimal surgical technique for the treatment of bowel endometriosis must consider different variables, including the number of lesions, eventual multifocal lesions, as well as length, width and grade of infiltration into the bowel wall. Except for some major and widely accepted indications regarding bowel resection, established international guidelines are not clear on when to employ a more conservative approach like rectal shaving or discoid resection, and when, instead, to opt for bowel resection. Damage to the pelvic autonomic nervous system may be avoided by detection of the middle rectal artery, where its relationship with female pelvic nerve fibers allows its use as an anatomical landmark. To reduce the risk of potential vascular and nervous complications related to bowel resection, a less invasive approach such as shaving or discoid resection can be considered as potential treatment options. Additionally, the middle rectal artery can be used as a reference point in cases of upper bowel resection, where a trans mesorectal technique should be preferred to prevent devascularization and denervation of the bowel segments not affected by the disease.

Abstract
BACKGROUND While shaving-induced erythema is a common inflammatory skin issue, there is a lack of quantitative information on how well a shaving product performs in this regard. In this study, multispectral near-infrared spectroscopy (NIRS) imaging was used to quantitatively and qualitatively measure the extent of shaving-induced erythema. The research compares a safety razor and a cartridge razor to evaluate their impact on skin irritation. MATERIALS AND METHODS Fifty-nine healthy male volunteers without pre-existing skin conditions were enrolled. Basic demographics were recorded, and participants' faces or necks were imaged before shaving. Shaving was conducted on the right side of the face/neck with the safety razor and on the left side of the face/neck using the 3-blade cartridge razor. Images were captured immediately after shaving, at 5 and 10 min post-shaving. RESULTS Tissue oxygen saturation (StO2) measurements demonstrated that the safety razor induced significantly less erythema than the cartridge razor. Immediately after shaving, 40.3% of skin shaved with the safety razor had erythema compared to 57.6% for the cartridge razor. At 5 min post-shaving, 36.5% of skin shaved with the safety razor had erythema, compared to 53.8% of cartridge razor. CONCLUSIONS Multispectral NIRS revealed significant differences in shaving-induced erythema between safety and cartridge razors. Safety razors demonstrated a lower incidence of erythema, suggesting a potential advantage for individuals prone to skin irritation. This study contributes valuable insights into skin irritation and highlights the potential of multispectral NIRS in dermatology research.

Abstract
Introduction The removal of unwanted hair is a widespread grooming practice adopted by both males and females. Although many depilatory techniques are now available, shaving remains the most common, despite its propensity to irritate skin. Current techniques to investigate the impact of shaving regimes on skin health rely on costly and lengthy clinical trials, which hinge on recruitment of human volunteers and can require invasive biopsies to elucidate cellular and molecular-level changes. Methods Well-characterised human skin equivalent technology was combined with a commonplace dermatological technique of tape stripping, to remove cellular material from the uppermost layer of the skin (stratum corneum). This method of exfoliation recapitulated aspects of razor-based shaving in vitro, offering a robust and standardised in vitro method to study inflammatory processes such as those invoked by grooming practices. Results Tape strip insult induced inflammatory changes in the skin equivalent such as: increased epidermal proliferation, epidermal thickening, increased cytokine production and impaired barrier function. These changes paralleled effects seen with a single dry razor pass, correlated with the number of tape strips removed, and were attenuated by pre-application of shaving foam, or post-application of moisturisation. Discussion Tape strip removal is a common dermatological technique, in this study we demonstrate a novel application of tape stripping, to mimic barrier damage and inflammation associated with a dry shave. We validate this method, comparing it to razor-based shaving in vitro and demonstrate the propensity of suitable shave- and skin-care formulations to mitigate damage. This provides a novel methodology to examine grooming associated damage and a platform for screening potential skin care formulations.

Abstract
INTRODUCTION Since 2021, an increase in cases of tinea capitis has been detected in adolescents who shave their hair with fade haircut. PATIENTS AND METHODS Multicenter retrospective observational study of cases of cephalic pole dermatophytosis with a history of having been acquired after frequent shaving in hairdressing. A call was made to dermatologists from the Spanish Academy of Dermatology and Venereology (AEDV) to provide cases observed between January 2021 and December 2022. Patients with microbiological confirmation by culture or direct examination with KOH were included. RESULTS 107 cases were collected, 106 of which were male. 78 non-inflammatory forms were observed; compared to 29 inflammatory. The most frequently isolated fungus was Trichophyton tonsurans (75.7 % of cases). The lesions appeared predominantly on the nape of the neck and temporal area. CONCLUSIONS the distribution by sex, age and lesional location seems to indicate that a new social trend, in which male adolescents regularly go to hairdressers to shave the occipital and temporal areas, would be the cause of this grouping of cases of ringworm of the scalp. The most frequent microorganism in our study (T. tonsurans) coincides with the most prevalent in our environment. This study shows an accumulation of cases that can be taken into account by competent Public Health agencies, which are responsible for ensuring compliance with the rules of disinfection of the material used for shaving.

Abstract
STUDY OBJECTIVE To compare functional outcomes, recurrence rate and pregnancy likelihood in patients undergoing conservative or radical surgery in patients with deep rectal endometriosis 7 years post-operatively. DESIGN Prospective study in a cohort of patients enrolled in a 2-arm randomized trial from March 2011 to August 2013. SETTING A tertiary referral center. PATIENTS 55 patients with deep endometriosis infiltrating the rectum. INTERVENTIONS Patients underwent either segmental resection or nodule excision by shaving or disc excision, depending on a randomization which was performed preoperatively using sequentially numbered, opaque sealed envelopes. MEASUREMENT AND MAIN RESULTS The primary endpoint was the number of patients experiencing one of the following symptoms: constipation, frequent bowel movements, anal incontinence or bladder dysfunction 24 months postoperatively. Secondary endpoints were values of gastrointestinal and overall quality of life scores. The 7 year-recurrence rates (new deep endometriosis nodule infiltrating the rectum) in the excision vs. the segmental resection arms were 7.4 % vs. 0% (P=.24). One of more symptoms included in the definition of the primary outcomes were recorded in 55.6% vs. 60.7% of patients (P=0.79). However, 51.9% vs. 53.6% of patients considered their bowel movements as normal (P=.99). An intention-to-treat comparison of overall quality of life scores did not find differences between the two groups 7 years postoperatively. At the end of the 7-year study period, 31 of the 37 patients who tried to conceive were successful (83.8%) including: 27 (57.4%) natural conceptions and 20 (42.6%) pregnancies resulting from ART procedures. Pregnancy rate was 82.4% vs. 85% in the two arms (P=.99). A 75.7% live birth rate was recorded. At the end of the follow up there were 15 women with one child (40.5%) and 13 women with 2 children (35.1%). During the 7-year follow- up, the reoperation rate was respectively 37% and 35.7% in each arm, P=0.84). Among the 27 reoperation procedures during the follow up period, 11 were postoperative complications (40.7%), 7 were necessary prior to ART management (25.9%), 8 were for recurrent abdominal or pelvic pain (29.6%) and one for midline ventral hernia following pregnancy (3.7%). CONCLUSIONS Our study did not reveal a significant difference in terms of digestive functional outcomes, recurrence rate, reoperation risk and pregnancy likelihood when conservative and radical rectal surgery for deep endometriosis were compared 7 years postoperatively. Postoperative pregnancy rate observed in our series is high.

Abstract
Context The treatment of allergic reactions to red tattoo dye is challenging in most cases, as local therapy often does not offer long-term improvement and laser therapy is considered relatively contraindicated by many authors owing to the risk of generalized side effects. Therefore, surgical removal of these tattoos is favored; shave excision is the method of choice, particularly for the removal of the entire dye. Aims The aim of this article was to retrospectively analyze the best post-operative outcome after surgical removal of allergic tattoo reactions using different excision techniques. Materials and Methods We compared the different surgical procedures performed on seven patients with single and multiple allergic tattoo reactions treated between 2013 and 2018. Results The best aesthetic results were achieved by superficial ablation of the inflammatory reaction, partially leaving tattoo remains in the skin. Conclusion Based on our experience with this small number of patients, a superficial removal of the tattoo without complete removal of the dye is, in most cases, sufficient to achieve healing. The remaining dye residues seem to be better tolerated by the immune system afterwards. Furthermore, the tattoo is often preserved in large parts.

Abstract
Deep endometriosis infiltrating the rectum remains a challenging situation to manage, and it is even more important when ureters and pelvic nerves are also infiltrated. Removal of deep rectovaginal endometriosis is mandatory in case of symptoms strongly impairing quality of life, alteration of digestive, urinary, sexual and reproductive functions, or in case of growing. Extensive preoperative imaging is required to choose the right technique between laparoscopic shaving, disc excision, or rectal resection. When performed by skilled surgeons and well-trained teams, a very high majority of cases of deep endometriosis nodule (>95%) is feasible by the shaving technique, and this is associated with lower complication rates regarding rectal resection. In most cases, removing a part of the rectum is questionable according to the risk of complications, and the rectum should be preserved as far as possible. Shaving and rectal resection are comparable in terms of recurrence rates. As shaving is manageable whatever the size of the lesions, surgeons should consider rectal shaving as first-line surgery to remove rectal deep endometriosis. Rectal stenosis of more than 80% of the lumen, multiple bowel deep endometriosis nodules, and stenotic sigmoid colon lesions should be considered as indication for rectal resection, but this represents a minority of cases.

Abstract
Hair removal practices have evolved from adhering to social, cultural, and religious traditions to meeting aesthetic standards. Hair removal methods can be divided into two categories: 1) depilation, which involves removing the hair shaft and includes shaving and chemical depilatories, and 2) epilation, which involves removing the hair shaft, follicle, and bulb, and includes plucking, threading, waxing, sugaring, lasers, intense pulsed light system, electrolysis, and photodynamic therapy. Furthermore, an eflornithine hydrochloride 13.9% cream (Vaniqa®, neither an epilatory or depilatory technique), has been US FDA- and Health Canada-approved to slow the rate of facial hair growth and to be used in combination with other hair removal methods. All methods are temporary except for electrolysis, and each technique has advantages and disadvantages in terms of efficacy and adverse events. Importantly, most studies examining the efficacy of hair removal techniques are limited to darker hair and fairer skin, and further research is required especially for those with light-colored hair.

Abstract
1. This study evaluated photohydroionisation efficiency on the disinfection of new shavings used as substrate for litter in the poultry industry, pre-inoculated with bacterial, fungal and viral agents.2. Each replicate consisted of 250 g of new shavings sterilised by autoclaving, challenged with bacterial (Escherichia coli, Staphylococcus aureus, and Salmonella enterica, serovar Abony), fungal (Saccharomyces cerevisiae) and viral inoculum (Gumboro disease virus). The experiment consisted of six replicates at four times (0, 1, 5 or 10 min exposure) of photohydroionisation. The disinfection process was performed in a bench photohydroionisation device with four ultraviolet lamps. The agents inoculated in the shavings were analysed after the disinfection process.3. The counts of enterobacteria and total bacteria showed a quadratic effect. In contrast, the counts of fungi and viruses showed a negative linear effect with an increase in the time of photohydroionisation. The enterobacteria showed a linear response plateau effect (LRP), with a minimum time point of 5.498 minutes at a minimum contamination of 0.666 CFU/g and a reduction of 82.27% of the pre-established inoculum. Total bacteria had an LRP effect with a minimum time point of 1.902 minutes at minimum contamination of 1.739 CFU/g and a reduction of 50.0% of the pre-established inoculum. An LRP effect was found for fungi, with a minimum time point of 7.931 minutes in minimum contamination of 3.380 CFU/g, and with a reduction of 11.0% of the pre-established inoculum. For viruses, there was an LRP effect with a minimum time point of 5.012 minutes in minimum contamination of 0.000 viral titre per 100 g of shavings, which was reduced by 100% of the pre-established inoculum.4. Photohydroionisation in the disinfection of new shavings used as poultry litter has partial potential as a microbiological control tool, as a complete reduction occurred only for the viruses, whereas for bacteria and fungi only partial reductions of these microorganisms were observed.

Abstract
The preoperative work-up and optimal surgical approach to colorectal endometriosis is a highly studied topic lacking definitive recommendations. Synthesis of the available data can be extremely challenging for surgeons due to the heterogeneity of existing comparisons, a variety of studied surgical outcomes, and a predominant focus on operative complications. While these considerations are extremely important for surgeons performing such complex gynaecologic surgery there is still much to be desired with regards to evidence based guidelines for the preoperative assessment and surgical technique for colorectal endometriosis. Having an established guideline stating in which clinical situations endometriosis surgeons should performing rectovaginal shaving, versus discoid excision, versus segmental resection would be extremely important for all pelvic surgeons, even those operating in high-volume centres dedicated to the surgical management of complex endometriosis. This perspective highlights the shortcomings of the available data and attempts to create an algorithm surgeons can follow when performing surgery for colorectal endometriosis. This algorithm is based on our expert opinion after synthesising available data.

Abstract
Simple Summary Tracheal invasion is a poor prognostic factor in well-differentiated thyroid cancer. Appropriate resection can improve the prognosis and maintain the patient’s quality of life. Shaving resection for superficial tracheal invasion is minimally invasive because it does not involve the tracheal lumen, despite the problematic risk of local recurrence. Window resection for tracheal mucosal and luminal invasion provides good tumor control and does not cause postoperative airway obstruction; however, the need for surgical closure of the tracheocutaneous fistula is a disadvantage of this method. Circumferential (sleeve) resection and end-to-end anastomosis are highly curative, but the risk of fatal complications, such as anastomosis dehiscence, is a concern. Abstract Well-differentiated thyroid carcinoma (WDTC) is a slow-growing cancer with a good prognosis, but may show extraglandular progression involving the invasion of tumor-adjacent tissues, such as the trachea, esophagus, and recurrent laryngeal nerve. Tracheal invasion by WDTC is infrequent. Since this condition is rare, relevant high-level evidence about it is lacking. Tracheal invasion by a WDTC has a negative impact on survival, with intraluminal tumor development constituting a worse prognostic factor than superficial tracheal invasion. In WDTC, curative resection is often feasible with a small safety margin, and complete resection can ensure a good prognosis. Despite its resectability, accurate knowledge of the tracheal and peritracheal anatomy and proper selection of surgical techniques are essential for complete resection. However, there is no standard guideline on surgical indications and the recommended procedure in trachea-invading WDTC. This review discusses the indications for radical resection and the three currently available major resection methods: shaving, window resection, and sleeve resection with end-to-end anastomosis. The review shows that the decision for radical resection should be based on the patient’s general condition, tumor status, expected survival duration, and the treating facility’s strengths and weaknesses.

Abstract
The discovery of outer membrane proteins (OMPs) with desirable specificity and surface availability is a fundamental challenge to develop accurate immunodiagnostic assay and multivalent vaccine of pathogenic Vibrio species in food and aquaculture. Herein 101 OMPs were systemically screened from 4,831 non-redundant proteins of Vibrio parahaemolyticus by bioinformatical predication of signaling peptides, transmembrane (TM) α-helix, and subcellular location. The sequence homology analysis with 32 species of Vibrio spp. and all the non-Vibrio strains revealed that 15 OMPs were conserved in at least 23 Vibrio species, including BamA (VP2310), GspD (VP0133), Tolc (VP0425), OmpK (VP2362), OmpW (VPA0096), LptD (VP0339), Pal (VP1061), flagellar L-ring protein (VP0782), flagellar protein MotY (VP2111), hypothetical protein (VP1713), fimbrial assembly protein (VP2746), VacJ lipoprotein (VP2214), agglutination protein (VP1634), and lipoprotein (VP1267), Chitobiase (VP0755); high adhesion probability of flgH, LptD, OmpK, and OmpW indicated they were potential multivalent Vibrio vaccine candidates. V. parahaemolyticus OMPs were found to share high homology with at least one or two Vibrio species, 19 OMPs including OmpA like protein (VPA073), CsuD (VPA1504), and MtrC (VP1220) were found relatively specific to V. parahaemolyticus. The surface proteomic study by enzymatical shaving the cells showed the capsular polysaccharides most likely limited the protease action, while the glycosidases improved the availability of OMPs to trypsin. The OmpA (VPA1186, VPA0248, VP0764), Omp (VPA0166), OmpU (VP2467), BamA (VP2310), TolC (VP0425), GspD (VP0133), OmpK (VP2362), lpp (VPA1469), Pal (VP1061), agglutination protein (VP1634), and putative iron (III) compound receptor (VPA1435) have better availability on the cell surface.

Abstract
Background: Pseudomonas aeruginosa cell envelope-associated proteins play a relevant role in infection mechanisms. They can contribute to the antibiotic resistance of the bacterial cells and be involved in the interaction with host cells. Thus, studies contributing to elucidating these key molecular elements are of great importance to find alternative therapeutics. Methods: Proteins and peptides were extracted by different methods and analyzed by Multidimensional Protein Identification Technology (MudPIT) approach. Proteomic data were processed by Discoverer2.1 software and multivariate statistics, i.e., Linear Discriminant Analysis (LDA), while the Immune Epitope Database (IEDB) resources were used to predict antigenicity and immunogenicity of experimental identified peptides and proteins. Results: The combination of 29 MudPIT runs allowed the identification of 10,611 peptides and 2539 distinct proteins. Following application of extraction methods enriching specific protein domains, about 15% of total identified peptides were classified in trans inner-membrane, inner-membrane exposed, trans outer-membrane and outer-membrane exposed. In this scenario, nine outer membrane proteins (OprE, OprI, OprF, OprD, PagL, OprG, PA1053, PAL and PA0833) were predicted to be highly antigenic. Thus, they were further processed and epitopes target of T cells (MHC Class I and Class II) and B cells were predicted. Conclusion: The present study represents one of the widest characterizations of the P. aeruginosa membrane-associated proteome. The feasibility of our method may facilitates the investigation of other bacterial species whose envelope exposed protein domains are still unknown. Besides, the stepwise prioritization of proteome, by combining experimental proteomic data and reverse vaccinology, may be useful for reducing the number of proteins to be tested in vaccine development.

Abstract
PURPOSE To describe a novel technique to visualize vitreous base and the anterior hyaloid during vitrectomy for Rhegmatogenous Retinal Detachment (RRD). METHODS Retrospective, single-center study enrolling all patients who underwent vitrectomy for RRD between June 2015 and June 2018. After core vitrectomy and the necessary additional procedures, endodiathermy was activated near the edge of the peripheral vitreous. This created a heat-induced bubble stream and the bubbles were entangled in the vitreous base and anterior hyaloid. As a result, the vitreous base and anterior hyaloid were visualized and removed. RESULTS Between June 2015 and June 2018, a total of 210 cases of rhegmatogenous retinal detachment were treated with vitrectomy. Endodiathermy assisted vitreous base shaving and anterior hyaloid removal was used in those cases with a very low incidence of iatrogenic peripheral retinal breaks during vitreous base shaving (2%), and with no case of lens injury related to the technique. We achieved a final anatomical success of 95.2% in the study period after mean number of operations of 1.3 ± 0.2. Endodiathermy near the peripheral vitreous was not associated with any intraoperative or postoperative complications. CONCLUSION Endodiathermy assisted vitreous base and anterior hyaloid visualization is a safe adjuvant method that could help in achieving complete and rapid vitreous base shaving and anterior hyaloid removal.

Abstract
Background. Longstanding lymphedema can lead, especially when there is recurrence of erysipelas, to irreversible elephantiasis nostras verrucosa (ENV). This predisposes to new episodes of erysipelas, leading to further damage of the lymphatics and deterioration of the lymphedema as a whole. We report the results of 28 patients with primary lymphedema and surgical removal ENV of the forefoot and toes treated between 2006 and 2014. Method: Retrospective descriptive 5 year follow-up study of 28 patients with various diagnosis of primary lymphedema. Wound healing time, number of erysipelas, body mass index (BMI), recurrence of EVN and types of compression were documented during follow-up. Results: After preoperative multidisciplinary work up, operation of the toes with shaving and excision was performed within a conservative treatment program. During the follow up, the number of erysipelas attacks decreased dramatically (mean 17.6 vs. 0.6). Before treatment, no toecaps were used; and in follow up, it was a part of treatment. Recurrence of ENV was not observed. Compared to the literature with often BMI > 35, the mean BMI in our group was 30.0 (overweight). In 12 patients, we concurrently performed circumferential suction-assisted lipectomy for end-stage lymphedema of the leg. Conclusion: Although lymphedema patients are treated with garments during the maintenance phase, compression of the toes is often too challenging. Surgical removal of the verrucosis of toes is an effective therapeutic modality as part of an integrated lymphedema treatment program to restore the shape of the toes and enable the wearing of toecaps. This technique can also be effective for ENV of origins other than primary lymphedema. Although ENV is a generally accepted term, it can have undesirable connotations. We suggest using a more inclusive name such as lymphostatic verrucosis, because long-lasting lymphatic impairment is involved in all ENV and the term verrucosis is above discussion.

Abstract
STUDY QUESTION Is there a difference in functional outcomes and recurrence rate between conservative versus radical rectal surgery in patients with large deep endometriosis infiltrating the rectum 5 years postoperatively? SUMMARY ANSWER No evidence was found that long-term outcomes differed when nodule excision was compared to rectal resection for deeply invasive endometriosis involving the bowel. WHAT IS KNOWN ALREADY Functional outcomes of nodule excision and rectal resection for deeply invasive endometriosis involving the bowel are comparable 2 years after surgery. Despite numerous previously reported case series enrolling patients managed for colorectal endometriosis, long-term data remain scarce in the literature. STUDY DESIGN, SIZE, DURATION From March 2011 to August 2013, we performed a two-arm randomized trial, enrolling 60 patients with deep endometriosis infiltrating the rectum up to 15 cm from the anus, measuring >20 mm in length, involving at least the muscular layer in depth, and up to 50% of rectal circumference. Among them, 55 women were enrolled at one tertial referral centre in endometriosis, using a randomization list drawn up separately for this centre. Institute review board approval was obtained to continue follow-up to 10 years postoperatively. One patient requested to stop the follow-up 2 years after surgery. PARTICIPANTS/MATERIALS, SETTING, METHODS Patients underwent either nodule excision by shaving or disc excision, or segmental resection. Randomization was performed preoperatively using sequentially numbered, opaque, sealed envelopes, and patients were informed of randomization results. The primary endpoint was the proportion of patients experiencing one of the following symptoms: constipation (1 stool/>5 consecutive days), frequent bowel movements (≥3 stools/day), anal incontinence, dysuria or bladder atony requiring self-catheterization 24 months postoperatively. Secondary endpoints were values taken from the Knowles–Eccersley–Scott-symptom questionnaire (KESS), the gastrointestinal quality of life index (GIQLI), the Wexner scale, the urinary symptom profile (USP) and the Short Form 36 Health Survey (SF36). MAIN RESULTS AND THE ROLE OF CHANCE Fifty-five patients were enrolled. Among the 27 patients in the excision arm, two were converted to segmental resection (7.4%). One patient managed by segmental resection withdrew from the study 2 years postoperatively, presuming that associated pain of other aetiologies may have jeopardized the outcomes. The 5 year-recurrence rate for excision and resection was 3.7% versus 0% (P = 1), respectively. For excision and resection, the primary endpoint was present in 44.4% versus 60.7% of patients (P = 0.29), respectively, while 55.6% versus 53.6% of patients subjectively reported normal bowel movements (P = 1). An intention-to-treat comparison of overall KESS, GIQLI, Wexner, USP and SF36 scores did not reveal significant differences between the two arms 5 years postoperatively. Statistically significant improvement was observed shortly after surgery with no further improvement or impairment recorded 1–5 years postoperatively. During the 5-year follow-up, additional surgical procedures were performed in 25.9% versus 28.6% of patients who had undergone excision or resection (P = 0.80), respectively. LIMITATIONS, REASONS FOR CAUTION The presumption of a 40% difference concerning postoperative functional outcomes in favour of nodule excision resulted in a lack of power for demonstration of the primary endpoint difference. WIDER IMPLICATIONS OF THE FINDINGS Five-year follow-up data do not show statistically significant differences between conservative and radical rectal surgery for long-term functional digestive and urinary outcomes in this specific population of women with large involvement of the rectum. STUDY FUNDING/COMPETING INTEREST(S) No specific funding was received. Patient enrolment and follow-up until 2 years postoperatively was supported by a grant from the clinical research programme for hospitals in France. The authors declare no competing interests related to this study. TRIAL REGISTRATION NUMBER This randomized study is registered with ClinicalTrials.gov, number NCT 01291576. TRIAL REGISTRATION DATE 31 January 2011. DATE OF FIRST PATIENT’S ENROLMENT 7 March 2011.

Abstract
The standard of practice for perioperative hair removal is largely based on research that is outdated and underpowered. Although there is evidence to support the practice of clipping instead of shaving, current recommendations are to remove hair only when absolutely necessary. Human hair is bacteria-laden and challenging to disinfect, and clipping can be a safe method of hair removal that does not damage the skin. This article considers the removal of hair at the incision site with clippers, either before the patient enters the OR or in a manner that completely contains clipped hair, for every procedure, not just when absolutely necessary. There have been only two studies to date comparing clipping with no hair removal; more research is needed on this subject.

Abstract
STUDY QUESTION Is there a difference in functional outcome between conservative versus radical rectal surgery in patients with large deep endometriosis infiltrating the rectum 2 years postoperatively? SUMMARY ANSWER No evidence was found that functional outcomes differed when conservative surgery was compared to radical rectal surgery for deeply invasive endometriosis involving the bowel. WHAT IS KNOWN ALREADY Adopting a conservative approach to the surgical management of deep endometriosis infiltrating the rectum, by employing shaving or disc excision, appears to yield improved digestive functional outcomes. However, previous comparative studies were not randomized, introducing a possible bias regarding the presumed superiority of conservative techniques due to the inclusion of patients with more severe deep endometriosis who underwent colorectal resection. STUDY DESIGN SIZE, DURATION From March 2011 to August 2013, we performed a 2-arm randomized trial, enroling 60 patients with deep endometriosis infiltrating the rectum up to 15 cm from the anus, measuring more than 20 mm in length, involving at least the muscular layer in depth and up to 50% of rectal circumference. No women were lost to follow-up. PARTICIPANTS/MATERIALS, SETTING, METHODS Patients were enroled in three French university hospitals and had either conservative surgery, by shaving or disc excision, or radical rectal surgery, by segmental resection. Randomization was performed preoperatively using sequentially numbered, opaque, sealed envelopes, and patients were informed of the results of randomization. The primary endpoint was the proportion of patients experiencing one of the following symptoms: constipation (1 stool/>5 consecutive days), frequent bowel movements (≥3 stools/day), defecation pain, anal incontinence, dysuria or bladder atony requiring self-catheterization 24 months postoperatively. Secondary endpoints were the values of the Visual Analog Scale (VAS), Knowles-Eccersley-Scott-Symptom Questionnaire (KESS), the Gastrointestinal Quality of Life Index (GIQLI), the Wexner scale, the Urinary Symptom Profile (USP) and the Short Form 36 Health Survey (SF36). MAIN RESULTS AND THE ROLE OF CHANCE A total of 60 patients were enroled. Among the 27 patients in the conservative surgery arm, two were converted to segmental resection (7.4%). In each group, 13 presented with at least one functional problem at 24 months after surgery (48.1 versus 39.4%, OR = 0.70, 95% CI 0.22-2.21). The intention-to-treat comparison of the overall scores on KESS, GIQLI, Wexner, USP and SF36 did not reveal significant differences between the two arms. Segmental resection was associated with a significant risk of bowel stenosis. LIMITATIONS REASONS FOR CAUTION The inclusion of only large infiltrations of the rectum does not allow the extrapolation of conclusions to small nodules of <20 mm in length. The presumption of a 40% difference favourable to conservative surgery in terms of postoperative functional outcomes resulted in a lack of power to demonstrate a difference for the primary endpoint. WIDER IMPLICATIONS OF THE FINDINGS Conservative surgery is feasible in patients managed for large deep rectal endometriosis. The trial does not show a statistically significant superiority of conservative surgery for mid-term functional digestive and urinary outcomes in this specific population of women with large involvement of the rectum. There is a higher risk of rectal stenosis after segmental resection, requiring additional endoscopic or surgical procedures.

Abstract
Rituximab is an anti-CD20 mAb used in the treatment of B cell malignancies. Loss of surface CD20 Ag from the surface of target cells is thought to be one mechanism governing resistance to rituximab, but how this occurs is not completely understood. Two explanations for this have been proposed: antigenic modulation whereby mAb:CD20 complexes are internalized in a B cell intrinsic process and shaving, in which mAb:CD20 complexes undergo trogocytic removal by effector cells, such as macrophages. However, there is conflicting evidence as to which predominates in clinical scenarios and hence the best strategies to overcome resistance. In this study, we investigated the relative importance of modulation and shaving in the downregulation of surface mAb:CD20. We used both murine and human systems and treated ex vivo macrophages with varying concentrations of non-FcγR-interacting beads to achieve differential macrophage saturation states, hence controllably suppressing further phagocytosis of target cells. We then monitored the level and localization of mAb:CD20 using a quenching assay. Suppression of phagocytosis with bead treatment decreased shaving and increased modulation, suggesting that the two compete for surface rituximab:CD20. Under all conditions tested, modulation predominated in rituximab loss, whereas shaving represented an epiphenomenon to phagocytosis. We also demonstrate that the nonmodulating, glycoengineered, type II mAb obinutuzumab caused a modest but significant increase in shaving compared with type II BHH2 human IgG1 wild-type mAb. Therefore, shaving may represent an important mechanism of resistance when modulation is curtailed, and glycoengineering mAb to increase affinity for FcγR may enhance resistance because of shaving.

Abstract
Deep endometriosis (DE) remains the most difficult endometriotic entity to treat. Medical treatment for DE can reduce symptoms but does not cure the disease, and surgical removal of the lesion is required when lesions are symptomatic, impairing bowel, urinary, sexual, and reproductive functions. Although several surgical techniques such as laparoscopic bowel resection, disc excision, and rectal shaving have been described, there is no consensus regarding the choice of technique or the timing of surgery. Our review of publications reporting results and complications of surgery for rectovaginal DE reveals a relatively higher complication rate after bowel resection compared with shaving and disc excision, especially for rectovaginal fistulas, anastomotic leakage, delayed hemorrhage, and long-term bladder catheterization. Data show that shaving is feasible even in advanced disease. The risk of immediate complications after shaving and disc excision is probably lower than after colorectal resection, allowing for better functional outcomes. The presumed higher risk of recurrence related to shaving has not been demonstrated. For these reasons, surgeons should consider rectal shaving as a first-line surgical treatment of rectovaginal DE, regardless of nodule size or association with other digestive localizations. When the result of rectal shaving is unsatisfactory (rare cases), disc excision may be performed either exclusively by laparoscopy or by using transanal staplers. Segmental resection may ultimately be reserved for advanced lesions responsible for major stenosis or for several cases of multiple nodules infiltrating the rectosigmoid junction or sigmoid colon.

Abstract
Background: To report our experience of infections in deep brain stimulation (DBS) surgeries comparing shaving versus no shaving of cranial hair. Nonshaving is strongly preferred by patients due to aesthetic and psychological factors. Methods: This study is a prospective follow-up of the infection rate in 43 nonshaven DBS cases between April 2014 and December 2015 compared to our former infection rate with shaving in our center. Minimum follow-up was 6 months. All patients, except 7 epilepsy patients, received implantation of the electrodes together with the extension cables and internal pulse generator in one session. Results: In 43 nonshaven patients, a total of 81 electrodes were implanted or revised with a mean follow-up of 16 months. One patient (2.32%) developed an infection of the implanted DBS-hardware and was treated with antibiotics. Conclusion: In our experience nonshaving of cranial hair in DBS surgery does not lead to more infections when compared to shaving. We have changed our protocol to nonshaving based on these findings.

Abstract
The challenge of shaving is to cut the beard hair as closely as possible to the skin without unwanted effects on the skin. To achieve this requires the understanding of beard hair and male facial skin biology as both, the beard hair and the male facial skin, contribute to the difficulties in obtaining an effective shave without shaving-induced skin irritation. Little information is available on the biology of beard hairs and beard hair follicles. We know that, in beard hairs, the density, thickness, stiffness, as well as the rates of elliptical shape and low emerging angle, are high and highly heterogeneous. All of this makes it challenging to cut it, and shaving techniques commonly employed to overcome these challenges include shaving with increased pressure and multiple stroke shaving, which increase the probability and extent of shaving-induced skin irritation. Several features of male facial skin pose problems to a perfect shave. The male facial skin is heterogeneous in morphology and roughness, and male skin has a tendency to heal slower and to develop hyperinflammatory pigmentation. In addition, many males exhibit sensitive skin, with the face most often affected. Finally, the hair follicle is a sensory organ, and the perifollicular skin is highly responsive to external signals including mechanical and thermal stimulation. Perifollicular skin is rich in vasculature, innervation and cells of the innate and adaptive immune system. This makes perifollicular skin a highly responsive and inflammatory system, especially in individuals with sensitive skin. Activation of this system, by shaving, can result in shaving-induced skin irritation. Techniques commonly employed to avoid shaving-induced skin irritation include shaving with less pressure, pre- and post-shave skin treatment and to stop shaving altogether. Recent advances in shaving technology have addressed some but not all of these issues. A better understanding of beard hairs, beard hair follicles and male facial skin is needed to develop novel and better approaches to overcome the challenge of shaving. This article covers what is known about the physical properties of beard hairs and skin and why those present a challenge for blade and electric shaving, respectively.

Abstract
Cnidarian envenomations are the leading cause of severe and lethal human sting injuries from marine life. The total amount of venom discharged into sting-site tissues, sometimes referred to as "venom load", has been previously shown to correlate with tentacle contact length and sequelae severity. Since <1% of cnidae discharge upon initial tentacle contact, effective and safe removal of adherent tentacles is of paramount importance in the management of life-threatening cubozoan stings. We evaluated whether common rinse solutions or scraping increased venom load as measured in a direct functional assay of venom activity (hemolysis). Scraping significantly increased hemolysis by increasing cnidae discharge. For Alatina alata, increases did not occur if the tentacles were first doused with vinegar or if heat was applied. However, in Chironex fleckeri, vinegar dousing and heat treatment were less effective, and the best outcomes occurred with the use of venom-inhibiting technologies (Sting No More® products). Seawater rinsing, considered a "no-harm" alternative, significantly increased venom load. The application of ice severely exacerbated A. alata stings, but had a less pronounced effect on C. fleckeri stings, while heat application markedly reduced hemolysis for both species. Our results do not support scraping or seawater rinsing to remove adherent tentacles.

Abstract
BACKGROUND Two surgical approaches usually are used in the surgical management of deep infiltrating endometriosis of the rectum: the radical approach that mainly is based on colorectal resection and the conservative or symptom-guided approach that prioritizes conservation of the rectum. There are no data available that compare long-term functional digestive outcomes of 1 approach to the other. OBJECTIVE The purpose of this study was to compare long-term digestive outcomes in women who were treated by either rectal shaving or colorectal resection for deep endometriosis infiltrating the rectum. STUDY DESIGN A retrospective comparative study was performed. All women who were treated with surgery for deep endometriosis infiltrating the rectum by either shaving or colorectal resection at the University Hospital of Rouen from January 2005 to January 2010 were enrolled. Follow-up evaluation was carried out for a minimum of 5 years. Postoperative evaluation of digestive symptoms was performed by 4 standardized gastrointestinal questionnaires: the Gastrointestinal Quality of Life Index, the Knowles-Eccersley-Scott-Symptom score for constipation, the Wexner score for anal continence, and the Bristol Stool Score. Symptoms that were related to endometriosis, fertility, and disease recurrence were obtained from a specific questionnaire. RESULTS A total of 77 women were included. Three women were lost to follow up (3.9%), and 3 were treated by disc excision (3.9%). The mean follow-up time was 80±19 months. Forty-six women underwent conservative rectal shaving, and 25 women underwent colorectal resection. Patient characteristics and the severity of the disease were comparable in both groups. Patients who were treated by rectal shaving had significantly better Gastrointestinal Quality of Life Index values, lower Knowles-Eccersley-Scott-Symptom scores for postoperative constipation, and better anal continence. No statistically significant differences were revealed for postoperative pelvic pain. Rectal recurrence occurred in 8.7% of patients who were treated by conservative surgery: 4.3% underwent secondary colorectal resection and 4.3% were treated secondarily by rectal shaving. Consequently, avoiding a recurrence for merely 1 patient would have required 11 patients to undergo colorectal resection instead of shaving. CONCLUSION Our data suggest that, in patients who are treated for rectal endometriosis, colorectal resection does not improve long-term postoperative functional outcomes when compared with rectal shaving.

Abstract
Deep infiltrating endometriosis of the rectum is a severe disease concerning young women of reproductive age. Because it is a benign condition, aggressive surgical treatment and subsequent complications are not always accepted by young patients. Two surgical approaches exist: the radical approach, employing colorectal resection; and the conservative approach, based on rectal shaving or full-thickness disc excision. At present, the majority of patients with rectal endometriosis worldwide are managed by the radical approach. Conversely, as high as 66% of patients with colorectal endometriosis can be managed by either rectal shaving or full-thickness disc excision. Most arguments that used to support the large use of the radical approach may now be disputed. The presumed higher risk of recurrence related to conservative surgery can be balanced by a supposed higher risk of postoperative bowel dysfunction related to the radical approach. Bowel occult microscopic endometriosis renders debatable the hypothesis that more aggressive surgery can definitively cure endometriosis. Although most surgeons consider that radical surgery is unavoidable in patients with rectal nodules responsible for digestive stenosis, conservative surgery can be successfully performed in a majority of cases. In multifocal bowel endometriosis, multiple conservative procedures may be proposed, provided that the nodules are separated by segments of healthy bowel of longer than 5 cm. Attempting conservation of a maximum length of rectum may reduce the risk of postoperative anterior rectal resection syndrome and subsequent debilitating bowel dysfunction and impaired quality of life. Promotion of less aggressive surgery with an aim to better spare organ function has become a general tendency in both oncologic and benign pathologies; thus the management of deep colorectal endometriosis should logically be concerned, too.

Abstract
PURPOSE the purpose of this study was to evaluate whether treating partial-thickness articular-sided tears of the upper subscapularis (SSC) tendon with a dedicated suture anchor would result in an internal rotation strength improvement compared with simple shaving of the SSC tendon and footprint. METHODS twenty-six patients with a limited SSC tendon tear (equal or inferior to the most superior centimeter) in association with a posterosuperior cuff lesion were prospectively randomized to two treatments: repair with a dedicated suture anchor versus shaving of the tendon and footprint. The patients also underwent long head of the biceps (LHB) treatment and posterosuperior cuff tear repair. In each patient the following parameters were measured both preoperatively and at a minimum follow-up of 2.5 years: strength in internal rotation in the bear-hug testing position (using a digital tensiometer), DASH score and Constant scores. MRI assessment of tendon healing was performed at the final follow-up. RESULTS twenty of the 26 patients (76%) were reviewed after a mean follow-up time of 42 months: 11 patients had undergone SSC tendon repair and nine simple shaving. At final follow-up no significant differences were found between the repaired and shaving group in strength in internal rotation (9.5 ± 3.8 kg versus 10.3±5.4 kg; p=0.7). The DASH score and Constant score also failed to show significant differences between the two groups. Furthermore, no significant difference in SSC tendon healing rate was observed on MRI evaluation. CONCLUSIONS partial-thickness articular-sided tear of the upper SSC tendon in association with a posterosuperior rotator cuff repair and LHB treatment, when limited to the superior centimeter of the SSC tendon, shows a comparable performance in terms of strength in internal rotation either after simple shaving or a tendon-to-bone repair. LEVEL OF EVIDENCE Level II, prospective comparative study.

Abstract
Background Axillary hair can influence the development of underarm odor in men. Objective To compare different hair removal procedures and their impact on the effectiveness of standard soap washing (SW) in reducing male axillary odor. Methods The axillae of healthy Caucasian males (N = 30; 18–48 years of age) were randomized in a noncrossover, split body design. Two of four axillary treatments were evaluated per subject: clipped with scissors; wet shaved with a razor; waxed; and untreated. Odor evaluations were performed by trained assessors according to the American Society for Testing and Materials organization at baseline (24 h postcontrol SW), immediately, 12 and 24 h following treatment plus SW (Day 1). Further evaluations were conducted immediately and 24 h following SW on Day 2 and Day 3. Mean odor scores were calculated and an analysis of covariance conducted using baseline data as covariate. Results On Day 1, hair removal by clipping with scissors followed by SW offered no significant improvement in immediate odor control (27.2% reduction from baseline) when compared with SW alone. Both shaving and waxing followed by SW resulted in an immediate, significant reduction in axillary odor compared with SW alone (57.3% and 75.3% reduction, respectively; P < 0.0001). This improvement persisted for 24 h after shaving (P = 0.0682). Further, a single shaving treatment significantly improved the immediate effectiveness of SW on Day 1, Day 2, and Day 3 compared with SW alone (P < 0.05). Conclusions Blade shaving of the axillae can optimize the cleansing and odor reducing effectiveness of daily hygiene measures for men without the discomfort associated with waxing.

Abstract
Candida albicans is a human opportunistic fungus and it is responsible for a wide variety of infections, either superficial or systemic. C. albicans is a polymorphic fungus and its ability to switch between yeast and hyphae is essential for its virulence. Once C. albicans obtains access to the human body, the host serum constitutes a complex environment of interaction with C. albicans cell surface in bloodstream. To draw a comprehensive picture of this relevant step in host-pathogen interaction during invasive candidiasis, we have optimized a gel-free shaving proteomic strategy to identify both, human serum proteins coating C. albicans cells and fungi surface proteins simultaneously. This approach was carried out with normal serum (NS) and heat inactivated serum (HIS). We identified 214 human and 372 C. albicans unique proteins. Proteins identified in C. albicans included 147 which were described as located at the cell surface and 52 that were described as immunogenic. Interestingly, among these C. albicans proteins, we identified 23 GPI-anchored proteins, Gpd2 and Pra1, which are involved in complement system evasion and 7 other proteins that are able to attach plasminogen to C. albicans surface (Adh1, Eno1, Fba1, Pgk1, Tdh3, Tef1, and Tsa1). Furthermore, 12 proteins identified at the C. albicans hyphae surface induced with 10% human serum were not detected in other hypha-induced conditions. The most abundant human proteins identified are involved in complement and coagulation pathways. Remarkably, with this strategy, all main proteins belonging to complement cascades were identified on the C. albicans surface. Moreover, we identified immunoglobulins, cytoskeletal proteins, metabolic proteins such as apolipoproteins and others. Additionally, we identified more inhibitors of complement and coagulation pathways, some of them serpin proteins (serine protease inhibitors), in HIS vs. NS. On the other hand, we detected a higher amount of C3 at the C. albicans surface in NS than in HIS, as validated by immunofluorescence.

Abstract
The relationship between deep fibrotic endometriosis of the rectum and digestive symptoms as well as the impact of surgical treatment on digestive complaints appears increasingly complex. With the exception of cases in which the disease leads to rectal stenosis, it seems likely that certain digestive symptoms are a result of cyclic inflammatory phenomena leading to irritation of the digestive tract and not necessarily the result of actual involvement of the rectum by the disease itself because they frequently occur in women free of rectal nodules. Functional or inflammatory bowel diseases and rectal hypersensitivity may be associated with pelvic endometriosis and consequently joepardize the hypothetical causal relationship between the presence of a rectal nodule and digestive complaints. Women treated surgically for rectal endometriosis may continue to experience postoperative digestive complaints, such as constipation. Despite successful surgery free of intra- and postoperative complications and significant improvement in well-being and pelvic pain, several unpleasant digestive symptoms may be incompletely cured by the surgery. Furthermore, de novo postoperative digestive complaints may occur after rectal surgery. Retrospective data suggest that performing colorectal resection is related to less favorable digestive functional outcomes than the use of conservative procedures such as shaving or full-thickness disc excision. These hypotheses need to be confirmed by prospective randomized trials comparing rectal radical and conservative approaches. Bearing in mind the complex relationship between rectal nodules, digestive symptoms and rectal surgery, particular care must be taken in the preoperative assessment of digestive function and in choosing the most suitable surgical procedure.

Abstract
Introduction: Conditions that cause curvature of the erect penis also lead to difficulties with intercourse. The present study presents an effective surgical treatment for congenital penile curvature. Methods: Between March 1996 and August 2004, 49 patients were diagnosed with congenital penile curvature at the Toho University Omori Hospital Reproduction Center, Tokyo. Of these, 27 eligible patients underwent surgical treatment. The operative technique used involved the tunica albuginea being exposed and a number of vertical incisions were made through its superficial layers. The superficial layer of the tunica albuginea was then resected using scissors. Inverted plication sutures were then placed in the raw surface of the corpus cavernosum using 2-0 nylon. In addition, 2-0 polyglactic acid (Vicryl) sutures were placed on either side of each nylon suture knot. Results: Of a total of 49 patients, 27 eligible patients underwent surgical treatment with no serious postoperative complications. All 27 patients were able to sustain intercourse. There were no new cases of erectile dysfunction, penile pain or penile shortening. There were no recurrences of penile curvature. Conclusions: This new partial thickness shaving, inverted sutures reinforced with dissolving sutures plication method is an extremely effective surgical treatment for congenital penile curvature, with a superior safety profile.
