The association between BCG scars and self-reported chronic diseases: A cross-sectional observational study within an RCT of Danish health care workers.

INTRODUCTION: The live-attenuated vaccines Bacillus Calmette-Guérin (BCG) and Vaccinia have been associated with beneficial non-specific effects. We assessed the prevalence of BCG and Vaccinia vaccine scars in a cohort of Danish health care workers and investigated the association between the presence of vaccine scars and self-reported chronic diseases. METHODS: Cross-sectional study utilizing baseline data collected during 2020-2021 at enrollment in a BCG trial aiming to assess the effect of BCG vaccination on absenteeism and infectious disease morbidity during the SARS-COV-2 pandemic. In Denmark, Vaccinia was discontinued in 1977, and BCG was phased out in the early 1980s. We used logistic regression analysis (adjusted for sex, birth year, and smoking status) to estimate the association between scar status and chronic diseases, providing adjusted Odds Ratios (aORs) with 95 % Confidence Intervals, for participants born before 1977, and born from 1965 to 1976. RESULTS: The cohort consisted of 1218 participants (206 males; 1012 females) with a median age of 47 years (Q1-Q3: 36-56). Among participants born 1965-1976 (n = 403), who experienced the phase-outs, having BCG and/or Vaccinia scar(s) vs. having no vaccine scars yielded an aOR of 0.51 (0.29-0.90) of self-reported chronic disease; an effect primarily driven by BCG. In the same birth cohort, having vaccine scar(s) was most strongly associated with a lower prevalence of chronic respiratory and allergic diseases; the aORs being 0.39 (0.16-0.97) and 0.39 (0.16-0.91), respectively. CONCLUSION: Having a BCG scar was associated with a lower prevalence of self-reported chronic disease.

Epidemiology and Predictors for Cervical Burn Scar Contractures: A Multicenter Cohort Study.

Cervical burn scar contracture (BSC) affects many important neck functions and the patients' quality of life. However, it remains unclear which patients have a higher risk of neck BSCs. This study aimed to describe the epidemiology and identify the independent risks of cervical BSC formation and severity. Clinical and demographic data of 106 patients with burn scars were retrospectively collated and analyzed from 3 different Chinese hospitals between December 2016 and December 2020. Both univariate and multivariate logistic regression analyses were performed to identify the independent risks for BSC formation and severity at 12 months postburn. Lateral flexion was the most common plane of motion (POM) limited by contractures (29.4%), whereas the POM most commonly limited by severe contractures was the extension (24.6%). Most patients with contractures had those in 3 to 4 POMs (72.1%). Neck skin grafting was an independent risk factor for BSC formation, and cervical and cervicothoracic skin grafting were independent risk factors for BSC severity. These results may help to identify high-risk patients with contractures in the early stages of burns to carry out individualized early prevention and treatment.

Incidence and ultrasonographic characteristics of cesarean scar niches after uterine closure by double-layer barbed suture: A prospective comparative study.

OBJECTIVE: To compare the ultrasonographic features of uterine scars and clinical symptoms after cesarean delivery (CD) using barbed and conventional smooth sutures. METHODS: This case-control study enrolled women who underwent primary CD at 37 weeks of pregnancy or later. The uterus was closed using either double-layer unidirectional barbed suture or conventional double-layer smooth suture. Ultrasound scans of the uterine scar and evaluations of menstrual patterns were performed at 6, 12, and 24 months after surgery. RESULTS: In all, 102 patients underwent uterine closure with barbed suture, while 135 patients underwent smooth suture. At 6 months, patients in the barbed group had a lower incidence of uterine niches (20.2% vs 32.6%) that were also shallower in depth (P < 0.001). Lower incidence of niches was also observed in the barbed group at 12 and 24 months (P = 0.043 and 0.048, respectively). At these two follow-up times, the smooth group had a higher number of patients reporting postmenstrual spotting (P < 0.05) and more postmenstrual spotting days per month (P < 0.050). CONCLUSION: The use of double-layer barbed suture during CD was associated with a lower incidence of scar niches and a more favorable menstrual pattern compared with the use of smooth suture.

Donor site morbidity after computer assisted surgical reconstruction of the mandible using deep circumflex iliac artery grafts: a cross sectional study.

BACKGROUND: Computer Assisted Design and Computer Assisted Manufacturing (CAD/CAM) have revolutionized oncologic surgery of the head and neck. A multitude of benefits of this technique has been described, but there are only few reports of donor site comorbidity following CAD/CAM surgery. METHODS: This study investigated comorbidity of the hip following deep circumflex iliac artery (DCIA) graft raising using CAD/CAM techniques. A cross-sectional examination was performed to determine range of motion, muscle strength and nerve disturbances. Furthermore, correlations between graft volume and skin incision length with postoperative donor site morbidity were assessed using Spearman's rank correlation, linear regression and analysis of variance (ANOVA). RESULTS: Fifteen patients with a mean graft volume of 21.2 ± 5.7 cm3 and a mean incision length of 228.0 ± 30.0 mm were included. Patients reported of noticeable physical limitations in daily life activities (12.3 ± 11.9 weeks) and athletic activities (38.4 ± 40.0 weeks in mean) following surgery. Graft volume significantly correlated with the duration of the use of walking aids (R = 0.57; p = 0.033) and impairment in daily life activities (R = 0.65; p = 0.012). The length of the scar of the donor-site showed a statistically significant association with postoperative iliohypogastric nerve deficits (F = 4.4, p = 0.037). Patients with anaesthaesia of a peripheral cutaneous nerve had a larger mean scar length (280 ± 30.0 mm) than subjects with hypaesthesia (245 ± 10.1 mm) or no complaints (216 ± 27.7 mm). CONCLUSIONS: Despite sophisticated planning options in modern CAD/CAM surgery, comorbidity of the donor site following  iliac graft harvesting is still a problem. This study is the first to investigate comorbidity after DCIA graft raising in a patient group treated exclusively with CAD/CAM techniques. The results indicate that a minimal invasive approach in terms of small graft volumes and small skin incisions could help to reduce postoperative symptomatology.

Previous Abdominal Scars among Patients Undergoing Laparoscopic Cholecystectomy in a Tertiary Care Centre.

Introduction: Abdominal scars result from various open abdominal surgeries. Laparoscopic surgery in previous open abdominal surgery possesses various challenges to the surgeon like gaining access to the abdominal cavity, and difficulty in dissection due to dense adhesions from previous surgeries for various intraabdominal pathologies. This study aimed to find out the prevalence of previous abdominal scars among patients undergoing laparoscopic cholecystectomy in a tertiary care centre. Methods: A descriptive cross-sectional study was conducted among patients undergoing laparoscopic cholecystectomy in a tertiary care centre from 1 May 2022 to 30 April 2023 after taking ethical approval from the Institutional Review Committee. Palmer's point approach via Hassen open technique or direct optical entry was used for cases with previous abdominal scars to gain access to the abdominal cavity. Patients with symptomatic gallstone diseases were included in the study whereas patients with cholecystitis, pancreatitis, and previous cesarean scar were excluded. Convenience sampling method was used. The point estimate was calculated at a 95% Confidence Interval. Results: Among 160 patients undergoing laparoscopic cholecystectomy, previous abdominal scars was found in 40 (25%) patients. Conclusions: The prevalence of previous abdominal scars contributing to intraoperative and post-operative difficulties among patients undergoing laparoscopic cholecystectomy was found to be higher than in studies done in similar settings. Keywords: laparoscopic cholecystectomy; open surgery; prevalence.

Prevalence and Severity of Burn Scars in Rural Mozambique.

BACKGROUND: Burn injuries are common in low- and middle-income countries (LMICs) and their associated disability is tragic. This study is the first to explore burn scars in rural communities in Mozambique. This work also validated an innovate burn assessment tool, the Morphological African Scar Contractures Classification (MASCC), used to determine surgical need. METHODS: Using a stratified, population-weighted survey, the team interviewed randomly selected households from September 2012 to June 2013. Three rural districts (Chókwè, Nhamatanda, and Ribáuè) were selected to represent the southern, central and northern regions of the country. Injuries were recorded, documented with photographs, and approach to care was gathered. A panel of residents and surgeons reviewed the burn scar images using both the Vancouver Scar Scale and the MASCC, a validated visual scale that categorizes patients into four categories corresponding to levels of surgical intervention. RESULTS: Of the 6104 survey participants, 6% (n = 370) reported one or more burn injuries. Burn injuries were more common in females (57%) and most often occurred on the extremities. Individuals less than 25 years old had a significantly higher odds of reporting a burn scar compared to people older than 45 years. Based on the MASCC, 12% (n = 42) would benefit from surgery to treat contractures. CONCLUSION: Untreated burn injuries are prevalent in rural Mozambique. Our study reveals a lack of access to surgical care in rural communities and demonstrates how the MASCC scale can be used to extend the reach of surgical assessment beyond the hospital through community health workers.

A Comparison of Complication Rates in Wise Pattern Versus Vertical Breast Reduction.

BACKGROUND: Breast reduction has a well-chronicled history and remains a common reason for patients to seek plastic surgery consultation. The Wise pattern is the most common skin reduction pattern in the United States. Vertical pattern reduction is also widely used and offers the potential for decreased scar burden. Both patterns have been used with a variety of pedicles for preservation of the nipple areolar complex, which may also impact complication rate and patient satisfaction. There is a preponderance of literature on breast reduction surgery but limited comparative data on the safety profile of these patterns. The purpose of this article is to review the comparative literature, with emphasis on the overall risk of complications. METHODS: OVID and PubMed were used to query the literature for articles comparing complication rates in both Wise pattern and vertical breast reduction. Inclusion criteria were case series that encompassed both vertical and Wise pattern reductions and cited the rate of complications. Complications included in our analysis of total complication rate were as follows: hematoma, seroma, infection, dehiscence, fat necrosis, skin necrosis, and nipple areolar complex necrosis. We excluded standing cutaneous deformity as a complication. Articles that included oncoplastic breast reductions were also excluded. The primary analysis was an inverse variance-weighted random-effect meta-analysis of overall complication rate, with the association between the technique and overall complication rate quantified using odds ratios. RESULTS: Eight articles were identified that met inclusion criteria, representing 963 patients (525 Wise pattern and 438 vertical pattern). The overall complication rate pooled across the studies favored vertical pattern reduction, but the result was not definitive. CONCLUSIONS: Vertical pattern breast reduction can be done safely. Our statistical analysis found a trend toward decreased complications with vertical reductions, but did not reach statistical significance. Patients seeking breast reduction are a heterogeneous population with respect to breast size, degree of ptosis, body habitus, body mass index, comorbidities, and acceptance of scars. It remains important to individualize the approach to the patient and their needs. More quantitative, comparative data, especially from randomized controlled trials, would be useful to further evaluate the relative safety profiles of the 2 patterns.

Risk factors for renal scarring and clinical morbidity in children with high-grade and low-grade primary vesicoureteral reflux.

INTRODUCTION: Primary vesicoureteral reflux (VUR) is associated with urinary tract infections (UTIs) and renal damage. However, the importance of early diagnosis of VUR has been questioned. Moreover, most studies have few patients with high-grade VUR. Hence, we retrospectively analyzed a large cohort of patients with primary high-grade and low-grade VUR and assessed risk factors for renal damage and clinical morbidity. MATERIAL AND METHODS: We included patients (<18 years) at diagnosis with low-grade (1-3) or high-grade (4-5) primary VUR and noted their clinical history and presence of hypertension, low eGFR (<60ml/in/1.73 m2), renal scarring (focal or generalised) and reduced differential renal function (DRF; <45%). Risk factors were assessed (in patients and renal units) by logistic regression and generalised estimating equation. RESULTS: Of 399 primary VUR patients, 255 (64%) had high-grade VUR. Indications for voiding cystourethrogram were recurrent UTI (38%), first UTI (28%) and antenatal hydronephrosis (17%). At diagnosis, 252 (65%) had renal scars (focal in 170 [44%], generalised in 82 [21%]), and 188 (47%) had reduced DRF. High-grade VUR patients were more likely than low-grade VUR patients to have renal scarring (75% vs. 49%, p < 0.01), low eGFR (23% vs. 13%, p = 0.04) and significant hypertension (26% vs. 13%, p = 0.02). High-grade VUR was associated with generalised scars (odds ratio [OR] 11, p < 0.001), focal scars (OR 3.1, p < 0.001) and reduced DRF (OR 2.3, p < 0.001) shown in the table. Male sex was a risk factor for generalised scars (OR 2.3, p = 0.005). Focal scars were associated with recurrent UTIs (OR = 1.8, p = 0.004) and reduced DRF (OR 1.4, p = 0.027). Patients with multiple focal scars were diagnosed at an older age (2 years [1,4] than those with single scars (1.5 years [1,4] or no scars (1 year [0, 3]), p = 0.04). DISCUSSION: The prevalence of renal damage and clinical morbidity at VUR diagnosis was higher than other studies. High-grade VUR patients had a greater prevalence of renal damage, low eGFR and hypertension than low-grade VUR patients and was a risk factor for focal scars, generalised scars and reduced DRF. Focal scars were independently associated with recurrent UTI. Those with multiple scars were diagnosed later than those with single scars or no scars. CONCLUSIONS: High-grade VUR was associated with renal damage and clinical morbidity. Our study highlights the importance of diagnosing VUR early to identify patients who may warrant long-term follow-up and intervention to minimize morbidity.

The development of burn scar contractures and impact on joint function, disability and quality of life in low- and middle-income countries: A prospective cohort study with one-year follow-up.

OBJECTIVE: The aim of this study was to assess the development of burn scar contractures and their impact on joint function, disability and quality of life in a low-income country. METHODS: Patients with severe burns were eligible. Passive range of motion (ROM) was assessed using lateral goniometry. To assess the development of contractures, the measured ROM was compared to the normal ROM. To determine joint function, the normal ROM was compared to the functional ROM. In addition, disability and quality of life (QoL) were assessed. Assessments were from admission up to 12 months after injury. RESULTS: Thirty-six patients were enrolled, with a total of 124 affected joints. The follow-up rate was 83%. Limited ROM compared to normal ROM values was observed in 26/104 joints (25%) at 12 months. Limited functional ROM was observed in 55/115 joints (48%) at discharge and decreased to 22/98 joints (22%) at 12 months. Patients who had a contracture at 12 months reported more disability and lower QoL, compared to patients without a contracture (median disability 0.28 versus 0.17 (p = 0.01); QoL median 0.60 versus 0.76 (p = 0.001)). Significant predictors of developing joint contractures were patient delay and the percentage of TBSA deep burns. CONCLUSION: The prevalence of burn scar contractures was high in a low-income country. The joints with burn scar contracture were frequently limited in function. Patients who developed a contracture reported significantly more disability and lower QoL. To limit the development of burn scar contractures, timely access to safe burn care should be improved in low-income countries.

TULUA Lipoabdominoplasty: Transversal Aponeurotic Plication, No Undermining, and Unrestricted Liposuction. A Multicenter Study of 845 Cases.

BACKGROUND: TULUA (transverse plication, no undermining, full liposuction, neoumbilicoplasty, and low transverse abdominal scar) is the acronym for a radically different lipoabdominoplasty, intended to add simplicity, improve vascular safety, and attain good results. Modifications are unrestricted liposuction, no flap detachment, massive transverse infraumbilical plication, umbilicus amputation, neoumbilicoplasty, diminished tension wound closure, and low transverse scar settlement. The objectives of this article are to describe the technique and analyze a multicenter experience. METHODS: Sixty-eight plastic surgeons from 10 countries provided data for a retrospective review of 845 patients. Aesthetic results were scored by each surgeon using the Salles scale and analyzed in combination with complications to identify associations between patient and surgery characteristics. RESULTS: Of the patients, 95.5 percent were female, 19.7 percent were obese, 35.6 percent had prior scars, 10.4 percent had undergone previous abdominoplasty, 6.5 percent were postbariatric, and 6.6 percent were smokers. One patient had a kidney transplant, and 16.5 percent had comorbidities. Surgery characteristics varied widely, being on average as follows: lipoaspirate, 2967 ml; resection, 1388 g; and surgical time, 3.9 hours; 46.5 percent were not hospitalized. Averaged results were 8.68 of 10 points, besides adequate positioning and proportion of scar and umbilicus, without epigastric compensatory bulging (4.97 of 6 points). Overall complications were 16.2 percent, mostly seroma (8.8 percent); vascular-related complications (i.e., necrosis, wound dehiscence, and infection) constituted 2.7 percent. There were no fatalities. The logistic regression model demonstrated that smoking and obesity duplicate the risk of complications; if age older than 60 years is added, the risk of complication increases seven to nine times. Reported indications were multiple; however, pathologic diastasis was excluded. CONCLUSION: TULUA lipoabdominoplasty is a new reproducible procedure with good quantified results and an acceptable complication rate. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

The morbidity associated with paediatric burn wound escharotomies.

INTRODUCTION: An escharotomy is an effective surgical procedure for the rapid decompression of a constricting and unyielding eschar, to permit restoration of blood flow. However, an escharotomy is also a full-thickness incision, which adds additional scarring to the burn injury area. The cosmetic and functional morbidity of escharotomy scarring in children is poorly characterised. METHODS: Children who required a burn wound escharotomy at the Queensland Children's Hospital (QCH) between May 2011 and May 2020 were included. Demographics of these children were described. In addition, the number of operations for revision of escharotomy scars was recorded as an indicator of functional or cosmetic concern. RESULTS: A total of 19 patients required an escharotomy after a burn injury. Children with 1% to 96% TBSA burns required an escharotomy, with a median of 28% (IQR 10-39%) TBSA. Two patients (81% and 96% TBSA) died. Seventy-one percent (12/17) of survivors had operative revisions of their escharotomy scars. The median time from burn to first scar intervention was 35 weeks (IQR 19-70 weeks). CONCLUSION: There is substantial morbidity associated with escharotomies in children. Further investigation of the current methods of decompression after burn injury, and the long-term morbidity of escharotomy, is required.

Infantile Hemangiomas Cleared by Combined Therapy With Pulsed Dye Laser and Propranolol.

BACKGROUND: Oral propranolol is the first-line therapy for infantile hemangioma. Combining it with pulse dye laser (PDL) (595nm-long PDL) could reduce treatment duration and sequelae incidence and severity. OBJECTIVE: To determine the effect of PDL-propranolol treatment on duration to cure and sequelae. METHODS: All consecutive patients with infantile hemangioma who were cured by PDL-propranolol treatment were identified. RESULTS: In the 27 cases, average age at treatment start was 4.3 ± 3.8 months, mean tumor diameter was 11.1 ± 14.0 cm2, and tumor-type was most common (72.4% of lesions). The patients received 9.8 ± 10.5 PDL sessions. After ensuring patients had no physical contraindications, including heart disease, oral propranolol was started at 1 mg/kg/d, increased up to 3 mg/kg/d as a maintenance dose. Mean propranolol treatment duration was 11.1 ± 4.9 months. Total treatment duration was 15.3 ± 10.8 months. CONCLUSION: Our data in the context of recent literature suggest combining propranolol with PDL may reduce propranolol duration without increasing harms.

Modifiable and non-modifiable epidemiological risk factors for acne, acne severity and acne scarring among Malaysian Chinese: a cross-sectional study.

BACKGROUND: Acne vulgaris, a highly prevalent multifactorial inflammatory skin disease, can be categorised into different severity and scarring grades based on the type, number, and severity of lesions. While many epidemiology studies have investigated the risk factors for acne presentation, fewer studies have specifically studied the risk factors for acne severity and scarring. Therefore, this study investigated the prevalence of acne, acne severity and scarring grades, and their associated non-modifiable and modifiable epidemiological risk factors among Malaysian Chinese. METHODS: A total of 1840 subjects (1117 cases/723 controls) completed an investigator-administered questionnaire as part of a cross-sectional study, which include socio-demographics, familial history, lifestyle factors, dietary habits, and acne history. Acne cases were further evaluated for their severity (n = 1051) and scarring (n = 1052) grades by a trained personnel. RESULTS: Majority of the acne cases (up to 69%) had mild acne or Grade 1/2 scarring, while 21.6% had moderate/severe acne and 5.5% had Grade 3/4 scarring. Males had significantly higher risk of presenting with higher grades of acne scarring. Those who had acne, regardless of severity and scarring grades, had strong positive familial history (either in parents and/or sibling). Frequent consumption (most or all days) of foods that are commonly consumed during breakfast (butter, probiotic drinks, cereals and milk) decreased the risk for acne presentation and higher acne scarring, while periodic consumption (once/twice per week) of nuts and burgers/fast food decreased the risk for higher acne severity. Alcohol drinking was significantly associated with increased risk for acne presentation, while paternal, parental and household smoking were associated with reduced risk of more severe acne. CONCLUSIONS: In conclusion, positive familial history is a strong predisposing factor in influencing acne presentation, severity and scarring. Frequent consumption of foods that are commonly consumed during breakfast is protective against acne presentation.

Upstage rate of radial scar/complex sclerosing lesion identified on core needle biopsy.

BACKGROUND: We assessed the cancer upstage rate of Radial Scars (RS), and Complex Sclerosing Lesions (CSL), and risk-stratified lesions based on radiological and pathological features. METHODS: Characteristics of RS/CSL treated from 2013 to 2018 were examined for features associated with cancer. RESULTS: 78 RS/CSL were found on core needle biopsy (CNB) and surgically excised. 9 (11.5%) lesions were upstaged. Upstaged patients were older (66 vs 51, p = 0.033). More upstaged lesions were accompanied by a mass on both mammography (87.5% vs. 30.0%, p = 0.005) and ultrasound (100.0% vs. 62.8%, p = 0.043). 20.5% of lesions biopsied under ultrasound guidance with small needles (14-18G) were upstaged, but no lesions biopsied under stereotactic guidance with large needles (9-12 G) with vacuum assistance were upstaged (p = 0.009). CONCLUSIONS: Excision of RS/CSL seen on CNB is warranted, especially if the patient is older, the CNB is performed under ultrasound guidance with small needles, or if a mass is present on imaging.

The spectrum of pediatric scarring alopecia: A retrospective review of 27 patients seen at Mayo Clinic.

BACKGROUND/OBJECTIVE: There are few studies examining pediatric scarring alopecia. The objective of this study is to characterize the clinicopathologic findings, comorbidities, and treatment outcomes of pediatric patients with scarring alopecia. METHODS: Retrospective review of patients under age 18 diagnosed with scarring alopecia at Mayo Clinic from 01/01/1992 through 02/05/2019. RESULTS: 27 patients met inclusion criteria with a mean age of 11.2 years and a racial breakdown of 85.2% (23) White, 11.1% (3) Black, and 3.7% (1) Multiracial. Clinical scarring was noted in most (23, 85.2%). Biopsy confirmed the diagnosis in most (24, 88.9%). The most common diagnoses were folliculitis decalvans (6, 22.2%), lichen planopilaris (6, 22.2%), aplasia cutis congenita (4, 14.8%), tinea capitis (4, 14.8%), and morphea (3, 11.1%). Comorbid depression (6, 22.2%) and anxiety (6, 22.2%) were prevalent. Of the patients who received follow-up, most who pursued treatment achieved stabilization (55.5%) or slowing of progression (27.8%), with 44.4% of those treated experiencing regrowth. Mean time to stabilization in the treated population was 19.6 months. Two patients did not pursue treatment, but received follow-up and these untreated patients did not experience hair regrowth. CONCLUSIONS: Most patients presented with clinically evident primary scarring alopecia. Biopsy may confirm the diagnosis. Active treatment should be pursued, and successful treatment often requires combination therapies. Time to stabilization often takes years. Screening for depression and anxiety should be pursued.

Radial Scars and Complex Sclerosing Lesions of the Breast: Prevalence of Malignancy and Natural History Under Active Surveillance.

BACKGROUND: When needle core biopsies (NCBs) of the breast reveal radial scar or complex sclerosing lesions (RSLs), excision is often recommended despite a low risk of malignancy in the modern era. The optimal management of NCBs revealing RSLs is controversial, and understanding of the natural history of unresected RSLs is limited. METHODS: We retrospectively analyzed pathology and imaging data from 148 patients with NCB revealing RSL without atypia from 2015 to 2019 to determine the prevalence of malignancy and the behavior of RSLs undergoing active surveillance (AS). RESULTS: The mean age of patients was 52 years, and most lesions were screen-detected (91%). The median lesion size was 6.0 mm (range 2-39). Most patients (66%, n = 98) underwent immediate surgery, while 34% (n = 50) of patients underwent AS, with a median follow-up of 16 months (range 6-51). Of the excised RSLs, 99% (n = 97) were benign and 1% (n = 1) revealed ductal carcinoma in situ (DCIS). In 17% (n = 17) of cases, additional high-risk lesions were discovered upon excision. Among the 50 patients undergoing AS, no lesions progressed on interval imaging. CONCLUSIONS: In this cohort, 99% of RSLs undergoing excision were benign, 1% revealed DCIS, and there were no invasive cancers. In the first study of patients with RSLs undergoing AS, we found that all lesions either remained stable or resolved. We propose that the vast majority of patients with RSL on NCB can be safely offered AS, and that routine excision is a low-value intervention.

Endoscopic Treatment of Previous Cesarean Scar Defect in Women with Postmenstrual Bleeding: A Retrospective Cohort Study.

OBJECTIVE: To compare the incidence of postmenstrual bleeding after hysteroscopic resection versus laparoscopic repair of previous cesarean scar defect (PCSD). MATERIALS AND METHODS: Retrospective analysis of computerized patient records. For the diagnosis of PCSD, patients underwent transvaginal ultrasound first without and then with saline-assisted sonohysterography. Hysteroscopic PCSD resection was performed under sonographic guidance, while laparoscopic repair was guided by hysteroscopy for the confirmation of scar margins. RESULTS: Records of 62 patients presenting with PCSD-related postmenstrual bleeding were included in analysis. Hysteroscopic surgery had significantly shorter operative time compared to the laparoscopic approach (Mean =30.9 vs 71.0 minutes; p < 0.001). Blood loss and hospital stay were significantly less (p < 0.001) in hysteroscopic resection (10.4 ± 4.6 ml and 2.1 ± 0.4 days) than in laparoscopic repair (36.6 ± 4 ml, and 4.6 ± 1 days). After surgical interventions, the postmenstrual bleeding was resolved or improved. The effectiveness rates of hysteroscopic resection and laparoscopic repair were 91.4% and 96.3%, respectively. Incidence of post-treatment postmenstrual bleeding was not significantly different between hysteroscopy and laparoscopy (OR= 1.29 [95% confidence interval 0.367, 4.86]; p = 0.662). Pretreatment postmenstrual bleeding was associated with time since cesarean section (B= -0.091 [-0.158, -0.023]; p = 0.01) and PCSD length (B = 0.502 [0.085, 0.919]; p = 0.019). CONCLUSION: Both hysteroscopic resection and laparoscopic repair of PCSD yield comparable efficacy in reducing postmenstrual bleeding. However, hysteoroscopic resection of PCSD is associated with comparatively shorter operative time, less blood loss, and shorter hospital stay.

Shave Excision Versus Elliptical Excision of Nonpigmented Intradermal Melanocytic Nevi: Comparative Assessment of Recurrence and Cosmetic Outcomes.

BACKGROUND: Nonpigmented intradermal melanocytic nevi (IMN) are benign lesions often removed for cosmetic reasons. There is no consensus as to the best technique for IMN excision. OBJECTIVE: To compare cosmetic outcomes and risk of recurrence after shave excision versus elliptical excision of IMN. MATERIALS AND METHODS: In this randomized clinical trial, patients underwent shave excision or elliptical excision with sutured closure of IMN of the face or back. Recurrence, patient satisfaction, cosmetic outcome, postoperative discomfort, scar size, discoloration, and presence of hypertrophic or keloid scars were evaluated at 3, 6, and 9 months. RESULTS: Overall, 145 nevi were removed from 45 patients (86.7% women, mean age 52.1 ± 12.5 years). The recurrence rate was 11.7%, occurring only after shave excision; 94.1% of recurrences were observed at 3-month follow-up. Shave excision was associated with less discomfort 48 hours after intervention but a greater likelihood of involved lateral and deep margins (p < .001). Scars were larger after elliptical excision and suture than after shave excision (p < .01). The mean patient satisfaction was higher in the shave excision group (p < .004). CONCLUSION: Shave excision of IMN is associated with higher rates of involved surgical margins and recurrence than elliptical excision but provides superior cosmesis and patient satisfaction.
