Raynaud's phenomenon of the nipple during breastfeeding: A case series. / Fenómeno de Raynaud en el pezón durante la lactancia: serie de casos.

Raynaud's phenomenon consists of excessive contraction of the blood vessels in response to various stimuli; although it usually affects the extremities, other locations are less frequently involved. This study focused on describing the characteristics of a series of women with Raynaud's phenomenon of the nipple. Through medical record review and direct communication with patients, data from 12 women diagnosed with Raynaud's phenomenon of the nipple between 2016 and 2023 were collected and analyzed. The following variables were assessed: age, symptoms, triggering factors, treatment, and duration of symptoms. In this case series, Raynaud's phenomenon of the nipple in breastfeeding women was more common among primiparous women around 10 days after delivery; pain was severe and, in most cases, improved with local and/or drug treatment, and did not limit the duration of breastfeeding.

El fenómeno de Raynaud consiste en la contracción excesiva de los vasos sanguíneos en respuesta a diversos estímulos y, si bien suele comprometer las extremidades, existen otras localizaciones menos frecuentemente afectadas. Este trabajo se enfoca en describir las características de una serie de mujeres con fenómeno de Raynaud en el pezón. Mediante revisión de historias clínicas y comunicación directa con las pacientes, se recopilaron y analizaron los datos de 12 mujeres con Raynaud del pezón entre 2016 y 2023. Se evaluaron variables como edad, síntomas, desencadenantes, tratamientos y duración de los síntomas. En esta serie de casos, el fenómeno de Raynaud del pezón en mujeres lactantes se manifestó con mayor frecuencia en primigestas alrededor del décimo día posparto; el dolor fue intenso, en la mayoría mejoró con tratamientos locales y/o farmacológicos, y no limitó la duración de la lactancia materna.

Prospective assessment of the quality of life and nipple sensation after gender-affirming chest surgery.

BACKGROUND: In the existing literature, assessing transgender patients' quality of life after surgery, especially using standardized surveys, is rare. The nipple sensation regarding the operating technique has neither been studied in a prospective nor standardized way. METHODS: For one year, we prospectively assessed transgender patients operated on for a gender-affirming chest surgery in our unit. Each patient answered the BREAST-Q© survey and the BODY-Q© chest module survey before and six months after the surgery. In addition, a measure of nipple sensation was performed using Semmes-Weinstein monofilaments pre-and post-operatively to compare surgical techniques. RESULTS: Fifty-one patients (102 breasts) were included in our study. The average age was 23.1 years and the average BMI was 24.8 kg/m2. Twenty-one patients (45%) had double incision and free nipple graft mastectomy, 14 (27%) patients had double incision and inferior pedicle mastectomy, while the 14 (27%) other patients had a semi-circular technique. Our study shows an improvement in all the scores of the surveys after surgery (p < 0.0001). Patients with double incision and inferior pedicle mastectomies rated a significantly higher satisfaction with nipples (p = 0.013) and significantly better sexual well-being (p = 0.007) than other techniques. In addition, preservation of nipple sensation was shown in patients operated by semi-circular technique (p < 0.001) and inferior pedicle technique (p < 0.0001). CONCLUSIONS: Our prospective study confirms the significant improvement in the quality of life of transgender patients after chest gender-affirming surgery. Double incision with inferior pedicle seems to provide better satisfaction with nipples, higher sexual well-being, and preservation of nipple sensation.

Successful correction of inverted nipple using silicone implants: A pioneering surgical approach.

Inverted nipples are commonly observed and can lead to challenges in breastfeeding, sexual experiences, and dissatisfaction with one's physical appearance. Currently, there is a lack of consensus on the optimal treatment approach. The use of a smooth silicone implant to reconstruct the nipple-areola complex in post-mastectomy breast reconstruction has recently been proposed. This study presents the first case using this approach in a patient with a grade II inverted nipple who previously failed conventional reconstructive surgical treatment.

Degree of satisfaction of women treated with reconstruction and dermopigmentation of the nipple-areola complex after breast reconstruction.

OBJECTIVE: To evaluate the degree of satisfaction of women treated with dermopigmentation and reconstruction of the Areola-Nipple Complex (ANC) after breast reconstruction, as well as their demographic profile and clinical-evolutionary characteristics. METHODS: Descriptive observational study including 128 women treated with dermopigmentation after oncologic breast reconstruction during 2018. In 2021 they were administered an adapted satisfaction questionnaire, which contains 27 items and categorizes satisfaction from 1-5, in addition other clinical-evolutionary and demographic variables were collected. RESULTS: Mean age was 51 (±9) years, 89.1% had previously undergone PDA reconstruction. Mean satisfaction with dermopigmentation was 4.4 (±0.88) and 3.79 (±1.06) for PDA reconstruction. Complications were rare, but 54.5% (n = 54) of the patients reported that the CAP reconstruction did not offer the expected projection, 91.6% (n = 98) that the color had faded and 51.4% (n = 55) would choose permanent tattooing. It was perceived that, the higher the satisfaction of the CAP, the higher the satisfaction of dermopigmentation, while the older the age and previous chemotherapy treatment the lower the color durability (p value ≤ 0.05). CONCLUSIONS: Patients who underwent reconstructive breast surgery show a high degree of satisfaction with dermopigmentation and surgical reconstruction of the PDA, but reiterate the low projecticity of the dermopigmentation and the surgical reconstruction of the PDA, but reiterate the low degree of satisfaction with the dermopigmentation.

Nipple Schwannoma: A Case Report and Literature Review on Nipple Mass.

Schwannomas are slow-growing benign tumors originating from the Schwann cells of the peripheral nerve sheaths. Herein, we report the first documented case of a schwannoma presenting as a painful nipple mass in a 32-year-old woman. This mass initially developed six years ago following a period of breastfeeding. Breast magnetic resonance imaging (MRI) scans revealed an iso-intense mass, with an approximate size of 2.2 cm, on a T1-weighted image with internal cystic changes. The mass exhibited heterogeneously delayed enhancement and restricted diffusion. Surgical excision was performed, and the diagnosis of cutaneous plexiform nipple schwannoma was confirmed histopathologically. A literature review revealed that the MRI findings of the nipple mass in our case were consistent with the common features of a schwannoma.

Initial nipple damages in breastfeeding women: analysis of photographic images and clinical associations / Lesiones tempranas del pezón derivadas de la lactancia materna: análisis de imágenes fotográficas y asociaciones clínicas / Lesões mamilares precoces decorrentes da amamentação: análise de imagens fotográficas e associações clínicas

ABSTRACT Objective: to analyze the initial nipple damage degree by breastfeeding practice and to associate findings with clinical manifestations of breastfeeding women. Methods: a retrospective, cross-sectional study with primary data and photographic images database from two randomized clinical trials. Photographic images were analyzed by two independent evaluators using the Nipple Trauma Score. For analysis, the chi-square, Mann-Whitney tests and Kappa coefficient were applied. Results: 115 breastfeeding women and their respective 186 photographic images were analyzed. The degree of agreement of evaluators using the Nipple Trauma Score was 93.6%. The nipple pain score during breastfeeding was moderate and compromised more than 25% of the nipple surface area. Conclusions: assistance to breastfeeding women should prioritize nipple pain intensity instead of the nipple damage size.

Conclusões: a assistência a mulheres que amamentam deve priorizar o nível de dor apresentado em detrimento do tamanho da lesão mamilar.

Sun-Cross Running Suture Combined with Transverse to Longitudinal Skin Closure to Correct Severe Inverted Nipple.

BACKGROUND: Inverted nipple deformity presents an unsatisfactory appearance that may induce an unpleasant sex life, but can also be associated with psychological discomfort and increased the functional problems, such as local irritation and inflammation. METHODS: Multiple techniques have been used to correct inverted nipples, but they mostly lead to different problems such as deficiency of the nerve or duct, recurrence of the inverted nipple, and hypopigmented scars in the areola. To minimize complications and maintain the stability of the reconstructed nipple, we presented a minimal incision technique that designed four 3-mm-sized horizontal microincisions, which ran a sun-cross through the periphery and the core of the nipple to push the nipple together, then a vertical suture ran longitudinal to close the transverse incision to stabilize the projection. RESULTS: This technique was performed in 71 patients classified as grade II or III of the inverted nipples, comprising 53 congenital cases and 18 patients with acquired deformity. Thirty-four patients had bilateral inverted nipples, and 37 patients had unilateral inverted nipple. During a mean follow-up period of 15 months, 70 corrected nipples remained raised without recurrence, and one nipple was found retracted at the outpatient clinic after 3 months. There were no serious complications associated with surgery regarding nipple necrosis, seven patients got temporary swelling, two patients got infected after touching water, three patients got extravasated blood, eight patients indicated that they touched scar under the nipple, and two patients reflected nipple dysesthesia. In the 15 months follow-up, the patients with Grade II nipple inversion maintained a nipple average height of 9.54 ± 0.95, and the patients with Grade III nipple inversion maintained a nipple average height of 9.19 ± 1.09, and 86.63% of patients were satisfied with their results. CONCLUSION: This is a simple, safe, effective and reliable technique that should be considered, providing sustained results over the long-term follow-up period with a high rate of stable eversion and low incidence of ischemia, necrosis, scarring and dysesthesia. The vertical scar of the transverse incision closure leads to an esthetic appearance without apparent scarring and minimizes the risk of an altered nipple sensation.

Raynaud Phenomenon of the Nipple: A Clinical Case Report.

Objective: In Raynaud's phenomenon of the nipple there is a change in color, accompanied by pain or discomfort during breastfeeding. Case report: A 29-years old female patient, breastfeeding, develops a severe bilateral nipple pain during and after breastfeeding and biphasic change in nipple color, with difficulties in the breastfeeding technique. She was medicated with nifedipine and recommended application of warm compresses to the nipples and use of electric breast pump, showing complete resolution after four weeks of treatment. Conclusion: Raynaud's phenomenon of the nipple should be considered in breastfeeding women who report nipple pain or discomfort. In clinical practice, nipple pain is a very frequent complaint, and responsible for many cases of early abandonment of breastfeeding. It is therefore essential to make an early diagnosis and implement a correct and immediate treatment.

A Clinical Score For Predicting Complications Following Breast Reduction.

Objectives: To establish a clinical score for morbidity prediction based on patient-related risk factors after breast reduction surgery. Method: The retrospective study was conducted at the Department of Plastic and Reconstructive Surgery, Kafrelsheikh University Hospital, Egypt, and comprised data of female patients with bilateral macromastia who underwent breast reduction, using the inferior pedicle invertedT technique between February 2019 and June 2020. After data retrieval, risk factors and complications were documented and related to the patients'risk factors Data was analysed using SPSS 20. RESULTS: Of the 30 cases, 20(66.7%) were aged ≥35 years, 16(53.3%) had body massindex ≥37kg/m2 and 27(90%) were non-smokers. The mean preoperative haemoglobin level was 12.15±1.115g/dL and the mean weight of tissue resected on both sides was 2074.17±696.12gm. Factors significantly associated with complications included smoking, suprasternal notch to nipple distance ≥38cm, haemoglobin <12.5g/dL, the weight of excised tissue ≥2000gm and a positive family history of macromastia. The total score of the morbidity prediction scale ranged 2-190, with the best cut-off value being ≥93. The scale had 100% sensitivity,specificity, positive predictive value, negative predictive value and 100 percent accuracy. CONCLUSIONS: Ability to predict postoperative surgical-site morbidity may optimise safety as well as outcome after reduction mammaplasty.

There is a need for refinement of the nomenclature, in order to assist in the diagnosis and adequate treatment.

Effectiveness of Hoffman's Exercise in Postnatal Mothers With Grade 1 Inverted Nipples.

BACKGROUND: Breastfeeding provides perfect nutrition for infants. The inverted nipples in mothers make breastfeeding more challenging. Besides surgical approaches, non-pharmacological interventions are also gaining importance. RESEARCH AIM: To evaluate the effectiveness of Hoffman's exercise on breastfeeding among postnatal mothers with grade I inverted nipples. METHOD: A quantitative approach with a parallel arm randomized controlled trial was used in the study. Postnatal mothers were screened for inverted nipples using a pinch test. Participants with at least one inverted nipple (Grade 1) were randomly allocated into two groups: the experimental group (supported with Hoffman's exercise; n = 28, 50.9% ) and the control group (without Hoffman's exercise; n = 27, 49.1%). The pre-test data, including demographics, nipple length, and breastfeeding assessment, were collected. Breastfeeding assessment was evaluated using the Bristol Breastfeeding Assessment Tool (BBAT). On the 3rd day, the post-test data, including nipple length and Breastfeeding Assessment, were collected among the groups. RESULTS: The BBAT assessment was significantly higher in the post-test compared to that of the pre-test in the participants provided with Hoffman's exercise. The nipple length was found to be higher in participants provided with Hoffman's exercise. Furthermore, the variables-including age, gravida, nipple problems, and delivery type-were not found to have any significant effect with either pre-test or post-test levels of breastfeeding. CONCLUSIONS: Hoffman's exercise was found to be an effective method to improve breastfeeding in Grade 1 nipple-inverted among post-natal mothers. This nipple exercise is inexpensive, easy to follow, and results in the successful initiation of breastfeeding. CLINICAL TRIAL REGISTRY AND REGISTRATION NUMBER: CTRI/2019/05/019279, May 23, 2019 (retrospectively registered).

Procedure for correction of inverted nipple using tiny incision with primary breast ducts reserved / 中华医学美学美容杂志

Objective:To discuss the procedure for correction of inverted nipple using tiny incision with primary breast ducts reserved.Methods:A total of 35 patients (63 sides) with primary inverted nipples from January 2006 to March 2019 were reviewed retrospectively. Tiny radial incisions were made on the areola around the base of the inverted nipple which had been pulled out. Without skin removed, shorten fiber bundles which caused nipple inverted were totally cut and released. While the primary breast ducts were preserved, purse-string suture was taken around the base of the nipple. The nipple protector was prepared by ourselves, and the nipple was pulled and suspended for 2-6 months.Results:Sixty-three sides of 35 patients with inverted nipples were successfully corrected by this minimally invasive surgery. There was no nipple necrosis. One patient developed mild swelling 3 weeks after operation, and the swelling subsided after symptomatic anti-inflammatory treatment. The average follow-up period was 39 months. After removing the nipple protector, 2 sides (2/63) had a certain degree of recurrence. The rest of the nipples had ideal shape, no obvious scar, good nipple feeling, and retained the possibility of lactation.Conclusions:The procedure for correction of inverted nipple using tiny incision with primary breast ducts reserved has advantages of minimal invasion, safety, less pain, while retaining the possibility of lactation in the future. The clinical effect is satisfactory. It is especially suitable for the correction of type Ⅰ and type Ⅱ inverted nipples.

Somatic mosaicism in STAG2-associated cohesinopathies: Expansion of the genotypic and phenotypic spectrum.

STAG2 is a component of the large, evolutionarily highly conserved cohesin complex, which has been linked to various cellular processes like genome organization, DNA replication, gene expression, heterochromatin formation, sister chromatid cohesion, and DNA repair. A wide spectrum of germline variants in genes encoding subunits or regulators of the cohesin complex have previously been identified to cause distinct but phenotypically overlapping multisystem developmental disorders belonging to the group of cohesinopathies. Pathogenic variants in STAG2 have rarely been implicated in an X-linked cohesinopathy associated with undergrowth, developmental delay, and dysmorphic features. Here, we describe for the first time a mosaic STAG2 variant in an individual with developmental delay, microcephaly, and hemihypotrophy of the right side. We characterized the grade of mosaicism by deep sequencing analysis on DNA extracted from EDTA blood, urine and buccal swabs. Furthermore, we report an additional female with a novel de novo splice variant in STAG2. Interestingly, both individuals show supernumerary nipples, a feature that has not been reported associated to STAG2 before. Remarkably, additional analysis of STAG2 transcripts in both individuals showed only wildtype transcripts, even after blockage of nonsense-mediated decay using puromycin in blood lymphocytes. As the phenotype of STAG2-associated cohesinopathies is dominated by global developmental delay, severe microcephaly, and brain abnormalities, we investigated the expression of STAG2 and other related components of the cohesin complex during Bioengineered Neuronal Organoids (BENOs) generation by RNA sequencing. Interestingly, we observed a prominent expression of STAG2, especially between culture days 0 and 15, indicating an essential function of STAG2 in early brain development. In summary, we expand the genotypic and phenotypic spectrum of STAG2-associated cohesinopathies and show that BENOs represent a promising model to gain further insights into the critical role of STAG2 in the complex process of nervous system development.

Complication after nipple-areolar complex tattooing performed by a non-medical person: A case report.

BACKGROUND: Compared to earlier, there has been an increase in the tattoo procedures for cosmetic purposes; and there has also been an increase in the tattoo procedures performed by non-medical personnel. In South Korea, only tattoos performed by a doctor are considered legal; however, there is still some debate over whether tattoo procedures performed by non-healthcare providers should be considered legal. CASE SUMMARY: A 28-year-old woman visited our hospital with pain in both nipples and heat sensation over the last 4 d. She had a history of a nipple tattoo performed by an unlicensed person. Pinpoint bleeding was noted in both areolar areas, and the exudate mixed with pus and orange color ink was discharged. Oral medication and tulle with foam dressing were performed under the impression of cellulitis and allergic reaction. After 4 wk, nipples remained dark brown in color, resulting in a color mismatch between the nipple and orange-colored areola. The size of the areola was also found to be distinctly asymmetrical after healing. This complication may have been caused by the use of illegal ink or unsanitary procedures, or a problem may have occurred in the post-tattoo management stage. CONCLUSION: Doctors use approved ink, aseptic procedure and appropriate postoperative care, and appropriate management can be performed in case of complications.

Surgical treatment of nipple hypertrophy, nipple-areola symmetrization, and functional preservation - A systematic review.

Nipple hypertrophy is a rare deformity that affects women's self-esteem. Several surgical techniques have been described for its treatment, but there is no gold standard technique, leaving the choice to the surgeon based on preference. A systematic review was performed using PRISMA guidelines on the surgical treatment of nipple hypertrophy over the period available. An illustrative case series was also included with 24 women, mean age 34.5 years, with nipple hypertrophy, treated with a functional preservation technique. This consisted of the removal of a circular segment of nipple tissue between the base and the tip, preserving its central structures, in conjunction with breast surgeries. The nipple-areola complex also underwent a procedure to achieve a 1:3 ratio. Postoperative follow-up was 12 months for the metric assessment, occurrence of complications, and tactile and pain sensitivities. A total of 1,064 articles were found, but only 19 were eligible. Most studies were classified with a low evidence level, homogeneous series, without the possibility of meta-analysis. Regarding the case series, the measurements of the vertical and horizontal axes varied, on average, 1.4 and 1.25 cm, respectively, in the preoperative period. No changes in the sensitivity were reported. No women had any of local or systemic complications. All of them were followed for at least 12 months, with preservation of the nipple-areola metrics. There is a need for better scientific evidence regarding the surgical treatment of nipple hypertrophy. The present surgical technique demonstrated the long-term preservation of nipple metrics without sensory or functional impairment.

Nipple ulcers of the nipple retractor technique to correct inverted nipples: A retrospective multivariate analysis.

BACKGROUND: A simple procedure using a nipple retractor to correct inverted nipples has been applied in clinical practice with stable and satisfactory aesthetic outcomes. Nipple ulceration and necrosis are rare and severe, with the causes unclear. OBJECTIVE: This study aimed to investigate the risk factors for the development of nipple ulcers in the nipple retractor technique. METHODS: A retrospective study was conducted on inverted nipple patients between January 2012 and September 2021. Clinical information, including baseline patient demographics, reproductive history, smoking, previous treatment, nipple inversion grades, nipple size, areola size, blood flow perfusion, and ulcer development, was collected. RESULTS: Twenty-five female patients with 44 inverted nipples were enrolled. Nipple ulcers were present in seven patients, four of whom were bilateral. Logistic regression analysis showed nipple inversion grades (Z = 2.105, OR 7.005, 95% CI: 1.144-42.898, p = 0.035) and relative perfusion of nipples (Z = -2.337, OR 0.969, 95% CI: 0.944-0.995, p = 0.019) were significantly associated with ulceration. The structural equation model demonstrated the interaction of related factors: nipple inversion grades increased by 0.411 points for ulcers (p = 0.004), while relative perfusion of nipples decreased by 0.647 points for ulcers (p < 0.001). CONCLUSION: Preoperative nipple inversion severity and post-operative nipple blood supply may be the risk factors for nipple ulcer development in the nipple retractor technique.

AOP key event relationship report: Linking androgen receptor antagonism with nipple retention.

In rat developmental and reproductive toxicity studies, nipple/areola retention (NR) in male offspring is a biomarker for reduced androgen signaling during development. This is because nipples normally regress in male rats in response to androgen signaling during critical stages of development. NR is thus included as a mandatory endpoint in several OECD test guidelines for assessment of chemicals, particularly as a readout for anti-androgenic effects relevant for reproductive toxicity. With the growing interest in developing Adverse Outcome Pathways (AOPs) to aid in chemical risk assessment, a more pragmatic approach has been proposed, whereby essential units of knowledge could be developed independently of complete AOPs, not least emergent key event relationships (KERs). Herein, we have developed a KER linking "androgen receptor antagonism" and "increased areola/nipple retention". The KER is based on a literature review conducted in a transparent semi-systematic manner in peer-reviewed databases with pre-defined inclusion criteria. Twenty-seven papers were included for development of the KER. The results support a qualitative relationship between the two key events (KEs) with a high weight of evidence; i.e., a causal relationship between androgen receptor (AR) antagonism and nipple retention in male rats exists.
