OBJECTIVE
Despite rising popularity and performance, studies evaluating the use of large language models for clinical decision support are lacking. Here, we evaluate ChatGPT (Generative Pre-trained Transformer)-3.5 and GPT-4's (OpenAI, San Francisco, California) capacity for clinical decision support in radiology via the identification of appropriate imaging services for two important clinical presentations: breast cancer screening and breast pain.
METHODS
We compared ChatGPT's responses to the ACR Appropriateness Criteria for breast pain and breast cancer screening. Our prompt formats included an open-ended (OE) and a select all that apply (SATA) format. Scoring criteria evaluated whether proposed imaging modalities were in accordance with ACR guidelines. Three replicate entries were conducted for each prompt, and the average of these was used to determine final scores.
RESULTS
Both ChatGPT-3.5 and ChatGPT-4 achieved an average OE score of 1.830 (out of 2) for breast cancer screening prompts. ChatGPT-3.5 achieved a SATA average percentage correct of 88.9%, compared with ChatGPT-4's average percentage correct of 98.4% for breast cancer screening prompts. For breast pain, ChatGPT-3.5 achieved an average OE score of 1.125 (out of 2) and a SATA average percentage correct of 58.3%, as compared with an average OE score of 1.666 (out of 2) and a SATA average percentage correct of 77.7%.
DISCUSSION
Our results demonstrate the eventual feasibility of using large language models like ChatGPT for radiologic decision making, with the potential to improve clinical workflow and responsible use of radiology services. More use cases and greater accuracy are necessary to evaluate and implement such tools.

PURPOSE
To evaluate clinical characteristics, quality of life (QoL) and effectiveness in patients with menstrual cycle disorders (MCDs) including abnormal uterine bleeding, dysmenorrhea and mastodynia/mastalgia related to premenstrual syndrome taking the Vitex agnus-castus (VAC) products Cyclodynon® or Mastodynon® in a real-world setting.
METHODS
A single-center retrospective longitudinal cohort study (3 ± 1 months), using data obtained from healthcare data archive and telephone interviews. The main study variables were changes in bleeding, menstrual pain, breast tenderness and patients' QoL.
RESULTS
Data from 1700 women with a mean age of 30.2 years (± 6.3) were analyzed. The most common MCDs were dysmenorrhea (43.8%) and mastodynia/mastalgia (21.1%). Three-month treatment with VAC extract substantially decreased the percentage of patients with irregular cycle (from 9.1% to 0.1%) and breast tenderness (from 39.9% to 0.8%). Improvement in bleeding intensity, frequency and menstrual pain was experienced by 83.4%, 79.2%, and 85.2% of the patients, respectively. When analyzed by disease category, these parameters improved in almost all dysmenorrhea patients, while they improved to a lesser extent in mastodynia/mastalgia patients. QoL improved in all aspects, but was reported by a higher proportion of dysmenorrhea patients compared to mastodynia/mastalgia patients. Treatment was overall well tolerated with a favorable safety profile.
CONCLUSION
These real-world data demonstrate the effectiveness of the VAC-containing products Cyclodynon® and Mastodynon® in the three-month treatment of MCDs, with a pronounced improvement in key disease symptoms and QoL. Intriguingly, while QoL was generally greatly improved, the response to VAC therapy varied depending on the type of underlying MCD.

Review
Gynecomastia is common, being present in 30% to 50% of healthy men. A general medical history and careful physical examination with particular attention to features suggestive of breast cancer often suffice for evaluation in patients without symptoms or those with incidentally discovered breast enlargement. Men with recent-onset gynecomastia or mastodynia need a more detailed evaluation, including selected laboratory tests to search for an underlying cause. Treatment depends on the cause and may include observation, withdrawal of an offending drug, therapy of an underlying disease, giving androgen or antiestrogen drugs, or plastic surgery.

Review
Cyclic mastalgia is one of the most prevalent problems in women of reproductive age and sometimes it is so severe that it influences their activities and requires treatment. The available drug treatments for mastalgia are not satisfactory and most patients have inclined towards complementary and alternative medicine including herbal medicines. Therefore, in order to evaluate the effectiveness and side effects of herbal medicines conducting systematic review studies and meta-analysis seems essential, thus this systematic review was conducted with the aim of determining the effect of herbal medicines on cyclic mastalgia and its probable side effects. The databases of Pubmed, Medline, Embase, ProQuest, Scopus, Web of science, Complementary Medicine Database, SID (Scientific information database), Magiran and Iranmedex were searched from 1997 to 2020 and limited only for English and Persian languages. The studies were appraised according to the Cochrane Collaboration's tool. Meta-analysis was conducted using RevMan software. Standardized mean difference (SMD) was calculated to assess an overall estimate of effectiveness for the continuous data. Odds ratio (OR) was calculated for dichotomous data. Thirty papers were included in the study. Meta-analysis of data demonstrated that herbal medicine was an effective method in reducing the severity of mastalgia compared to the placebo (SMD: -3.26, 95% CI: -5.05 to -1.46, p=0.00004). Subanalysis of data showed no difference between the effectiveness of herbal medicine on the severity of mastalgia compared to the pharmacologic treatment. This research demonstrated efficacy of herbal medicines in alleviating cyclic mastalgia. Therefore, these herbal medicines can be regarded as an alternative treatment for women suffering from cyclic mastalgia. However, due to the limited number of studies in relation to each specific herbal treatment, conducting further studies in this area is recommended.

BACKGROUND
Breast implant illness (BII) is extramammary systemic symptoms that are caused by breast implants. The emergence of this controversial topic has spurred patients with breast implants who are experiencing these symptoms to seek implant removal, hoping to feel better. This article presents novel outcomes and suggestions for plastic surgeons in managing BII using total capsulectomy and breast implant removal.
METHODS
In this retrospective cohort study conducted between 2016 and 2020, medical records of all patients undergoing breast implant removal were reviewed. Inclusion criteria consisted of all patients with history of breast implant placement presenting with mastodynia and capsular contracture on physical examination. Patients with history of implant-based reconstruction following mastectomy and patients who underwent implant exchange were excluded. All patients underwent bilateral implant removal and total capsulectomies.
RESULTS
A total of 200 patients who fulfilled the inclusion criteria were identified. Average age was 45.5 (range: 29-73) years and average body mass index was 26.28 (range: 19-36.8), with an average follow-up time of 5 months postoperatively. Of patients with a presentation of BII, 96% reported improved or complete resolution of their systemic symptoms after implant removal and total capsulectomy. A positive microbial culture was found in 68.5% of patients, and all culture-positive patients reported improvement post-treatment. The most common organisms found were (49.6%). There were no associations between implant characteristics and rate of positive microbiology findings.
CONCLUSIONS
Our study shows that implant removal with capsulectomy drastically improves BII symptoms. Further large prospective cohort studies are needed to better understand this entity.

Review
UNLABELLED
As the biological effects of progestins vary according to their molecular structure, it becomes essential to differentiate the various types of progestins, particularly with regard to the breast.
OBJECTIVE
The purpose of this review was to gather published data on the effects of a 19-norprogesterone derivative, nomegestrol acetate, on the breast. Materials and methods. All experimental and clinical published studies reporting data in the literature on nomegestrol acetate and breast were reviewed.
RESULTS
In experiments on steroid receptors, it was shown that nomegestrol acetate presents a high binding specificity and affinity for progesterone receptors, notably in normal and cancerous human breast tissues. It sharply inhibits synthesis of progesterone receptors in hormone-dependent T-47D human breast cancer cells grown in an estrogenic culture medium, thereby demonstrating its strong progestational activity. On the other hand, it does not bind to estrogen receptors and lacks any estrogenic potential, confirmed by the lack of induction of alkaline phosphatase activity of endometrial Ishikawa cells. Estrogen-induced synthesis of estrogen receptors is also inhibited by nomegestrol acetate, a major determinant of its strong intrinsic anti-estrogenic activity. Unlike androgenic progestins (e.g. 19-nortestosterone derivatives and medroxyprogesterone acetate) which may act indirectly on the breast by inducing modifications of sex hormone binding globulin (SHBG) and insulin-like growth factor-I (IGF-I), nomegestrol acetate is devoid of any androgenic activity. In studies carried out on the effects of progestins on enzyme activities involved in estradiol (E2) formation in breast tissue, nomegestrol acetate can control E2 levels in breast cancer tissue in vitro: it inhibits estrone sulfatase activity that converts estrone sulfate (E1S) to estrone (E1) and inhibits 17beta-hydroxysteroid dehydrogenase type 1 activity that converts E1 to E2, resulting in blockade of E2 bioformation in MCF-7 and T-47D human breast cancer cells. It also stimulates sulfotransferase activity and subsequently the transformation of non conjugated estrogens E1 and E2 into biologically inactive estrogen sulfates. In vitro studies on cell proliferation have demonstrated that nomegestrol acetate, on the one hand, is unable to stimulate proliferation of MCF-7 cells cultured in a medium devoid of estrogens and, on the other hand, can exert antiproliferative effects on T-47D cells grown in an estrogenic environment. Furthermore, studies on mammary apoptosis have shown that the withdrawal of nomegestrol acetate induces apoptosis peak of normal human breast epithelial cells in vitro and in vivo. In clinical trials carried out with premenopausal women, nomegestrol acetate administered in antigonadotropic sequence has demonstrated its efficacy in the treatment of cyclical mastodynia and early onset benign breast diseases. With postmenopausal hormone replacement therapy (HRT) combining estrogen and nomegestrol acetate, clinical trial results showed low incidence of mastodynia while under treatment as well as moderate increase in mammographic density, particularly with continuous combined regimens, however rapidly reversed by a short-term suspension of HRT. Noclinical data with this progestagen is available on breast cancer risk.
CONCLUSION
In addition to efficacy on mastodynia, in vitro and in vivo study results support the good tolerance of nomegestrol acetate on breast, in the short and medium term.

BACKGROUND
Many potential factors associated with Inflammatory Conditions of the Lactating Breast (ICLB) have been reported in the literature, by lactating mothers and clinicians. Clinicians, including general practitioners, lactation consultants and physiotherapists, require a clinical reasoning model that summarises associated or linked factors, to aid in the assessment, treatment, and prevention of ICLB. Thus, we aimed to adapt the existing Breastfeeding Pain Reasoning Model (BPRM), for use in the management of ICLB, using prior research and clinical audit data to guide adaptation. The existing BPRM categorises contributing factors for breastfeeding nipple pain, rather than ICLB.
METHODS
Factors linked with ICLB were identified from prior research and considered for inclusion into the existing model. Clinical data from a retrospective audit of ICLB patient notes at a private physiotherapy practice were also examined. Any factors identified from prior research that could not be identified in the clinical notes were not considered for inclusion into the existing model. Additional factors from the clinical notes that appeared repeatedly were considered for inclusion into the adaptation of the BPRM. A draft adapted model was created comprising all eligible factors, considering their counts and percentages as calculated from the clinical data. The research team iteratively examined all factors for appropriate categorisation and modification within the adapted model.
RESULTS
Prior research and data from 160 clinical notes were used to identify factors for inclusion in the adapted model. A total of 57 factors, 13 pre-existing in the BPRM and 44 extra identified from the prior research or clinical audit, comprised the draft adapted model. Factor consolidation and terminology modification resulted in a total of 34 factors in the final proposed adapted ICLB model. The three main categories, CNS modulation, External influences and Local stimulation, from the existing model were maintained, with one minor terminology change to the former Local stimulation category, resulting in 'Local influences' category. Terminology for five subcategories were modified to better reflect the types of factors for ICLB. The most common factors in the adapted model, calculated from the clinical audit population of mothers with ICLB, were employment (85%), high socioeconomic status (81%), antibiotic use during breastfeeding (61%), history of an ICLB (56%), any breast pump use (45%), multiparity (43%), birth interventions (35%), decreased milk transfer (33%), breastfeeding behaviour and practices (33%), nipple pain (30%) and fit and hold (attachment and positioning) difficulty (28%).
CONCLUSION
An ICLB-specific linked factors model is proposed in this paper. Clinicians treating mothers with ICLB can use this model to identify influencing and determining factors of ICLB clinical presentations and provide targeted education and effective treatment plans.

BACKGROUND
Despite numerous benefits, many mothers stop breastfeeding soon after birth. A common reason for this is the experience of pain or discomfort. One resource which women use to share their breastfeeding challenges and seek support are online forums. This study aimed to collect data from online forums to explore 1) usage of forums as social support for breastfeeding-related pain; 2) experiences of breastfeeding-related pain; 3) perceptions and strategies to deal with breastfeeding-related pain; and 4) the impact of pain on breastfeeding duration.
METHODS
Data was gathered through searches of online forums based in the UK and USA: Netmums, What to Expect and Mumsnet using key terms: 'painful breastfeeding' and 'sore breastfeeding'. Data extraction took place in July 2018 and included posts made between 2012 and 2018. Data included 123 posts and 193 replies, analysed using thematic analysis.
RESULTS
The first theme identified was 'variation in types of pain', highlighting the variety of painful experiences and their descriptions. In particular, this theme reveals the large variety of different types of pain women experience at different stages throughout their breastfeeding journey, as well as the different pain characteristic they focus on in the description of their experience (i.e., location, sensory or physical aspects). Secondly, the theme 'perceived causes and explanations for pain' revealed how women interpret pain experiences either due to a recognised condition or behavioural cause. The third theme 'cessation of breastfeeding related to pain' identified. How women experience both physical and psychological struggles (e.g., guilt) related to breastfeeding cessation, with pain being a main factor in considering cessation of breastfeeding. Finally, the theme 'shared experiences and support' identified women's strong need for both practical and emotional support to deal with pain. Many women look for this support through the knowledge exchange offered on the online forums.
CONCLUSIONS
Pain was a key reason for breastfeeding cessation, commonly associated with strong feelings of guilt. The online forums provide a unique form of social support for breastfeeding women to find ways to cope with the pain, while highlighting the urgent need for more appropriate antenatal education on realistic expectation surrounding breastfeeding.

Meta-Analysis Review
Mastalgia, or breast pain, is common among women which can lead to significant impairment in daily living. Hence, finding an effective treatment that can alleviate the symptom is very important. Thus, we carry out this study to determine the efficacy of evening primrose oil (EPO) for mastalgia treatment in women. The review included published randomised clinical trials that evaluated EPO used for treating mastalgia against a placebo or other treatments, irrespective of the blinding procedure, publication status, or sample size. Two independent authors screened the titles and abstracts of the identified trials; full texts of relevant trials were evaluated for eligibility. Two reviewers independently extracted data on the methods, interventions, outcomes, and risk of bias. The random-effects model was used for estimating the risk ratios and mean differences with 95% confidence intervals. Thirteen trials with 1752 randomised patients were included. The results showed that EPO has no difference to reduce breast pain compared to topical NSAIDS, danazol, or vitamin E. The number of patients who achieved pain relief was no different compared to the placebo or other treatments. The EPO does not increase adverse events, such as nausea, abdominal bloating, headache or giddiness, increase weight gain, and altered taste compared to a placebo or other treatments. EPO is a safe medication with similar efficacy for pain control in women with mastalgia compared to a placebo, topical NSAIDS, danazol, or vitamin E.

OBJECTIVE
Mastalgia is an important symptom affecting approximately 70% of women and it disrupts the quality of life especially due to the worry of having cancer. In our study, the type and severity of mastalgia symptom of patients who presented to the outpatient clinic with mastalgia complaint were assessed along with their physical examination findings and radiology results. The purpose of the study is to demonstrate the relationship between mastalgia and malignity when assessed in combination with the risk factors of patients.
MATERIALS AND METHODS
The age, family history, menopausal status, age at the first childbirth, menarche, presence/absence of hormone replacement therapy, type of mastalgia, comorbidities and examination findings of 104 patients, who presented to the General Surgery outpatient clinic with mastalgia symptom, were recorded and assessed in the light of radiological study results.
RESULTS
With respect to the mastalgia types of the patients, 38.5% had cyclic pain, 57.7% non-cyclic pain and 3.8% other types of pain. Mild mastalgia was present in 46.2% of the patients, moderate mastalgia in 24% and severe mastalgia in 29.8% of them. According to the BIRADS category, 48.1% of the patients were identified to have BIRADS 1 mass lesions, 39.4% BIRADS 2, 9.6% BIRADS 3 and 2.9% BIRADS 5 mass lesions. The patients who were identified to have BIRADS 5 mass lesions described non-cyclic and severe pain in the post-menopausal period. They had palpable masses along with the pain symptom.
CONCLUSION
Our study suggests that mastalgia symptom does not per se result in suspicion of malignancy, but physical examination and radiological imaging should also be used as needed for confirmation. Studies with a larger patient population are needed to shed light on the mastalgia epidemiology and its relationship with cancer.
