Day surgery in reduction mammaplasty - saving money or increasing complications?

BACKGROUND: The benefits of reduction mammoplasty procedures have been reported previously. However, to control the rise in public healthcare costs, we need to find ways of conducting these procedures safely and more cost-effectively. Our aim was to examine whether reduction mammaplasty performed in an outpatient setting has comparable surgical complication rates to those performed in an inpatient setting. We also investigated whether any savings gained from day surgery are still present after any possible indirect costs are considered. METHODS: The study population comprised 276 patients who underwent reduction mammaplasty in a single center between January 2019 and February 2021. Data were collected from patient medical records. The costs associated with the primary procedure and any possible additional expenses were calculated. Basic statistical comparisons were performed for propensity score-matched data. RESULTS: Complication rates, readmissions, number of contacts to the health care system, and need for additional surgical interventions were comparable between outpatients and inpatients. The basic costs for outpatients were 2990 euros per patient and 3923 euros for inpatients. Total costs after possible extra expenses were lower in day surgery as it was markedly more cost-effective than patients treated as inpatients. CONCLUSIONS: Reduction mammaplasties can be safely performed in an outpatient setting. Moreover, the emergence of complications is comparable to those performed in an inpatient setting. An outpatient setting produced significant cost savings not only in the immediate costs of primary surgery but also in the costs associated with possible complications and extra contacts to the healthcare system.

Autologous reconstructions are associated with greater overall medium-term care costs than implant-based reconstructions in the Finnish healthcare system: A retrospective interim case-control cohort study.

PURPOSE: Previous studies have mainly reported the short-term costs of different reconstruction techniques. Revision operations may increase costs in longer follow-up. Authors report medium-term data on different reconstruction methods. We hypothesised that the reconstruction method would affect not only the duration of reconstruction process but also total costs. METHODS: The reconstruction database was reviewed from 2008 to 2019. Women with autologous (deep inferior epigastric perforator, transverse musculocutaneous gracilis and latissimus dorsi [LD] without implant) and implant-based (implant and LD with implant) reconstructions were included. Variables evaluated included age, body mass index, smoking, comorbidities, radiotherapy, complications and readmissions. Risk factors for multiple revision surgeries were analysed. Time to definitive reconstruction and related costs were also calculated. RESULTS: In total, 591 patients with autologous reconstructions and 202 with implant-based reconstructions were included. The median follow-up time was 73 months. Definitive reconstruction was obtained in 443 days in implant-based reconstructions and in 403 days in autologous reconstructions (P = 0.050). Independent risk factors for multiple surgeries were younger age (P < 0.001) and comorbidity (P = 0.008). No statistically significant difference was observed in the rate of overall surgical procedures (P = 0.098), but implant-based reconstructions were more commonly associated with two or more planned operations (P = 0.008). Autologous reconstructions were associated with greater total cost ($22 052 vs. $18 329, P < 0.001). CONCLUSIONS: This review of reconstructions over a 12-year study period revealed that autologous reconstructions are associated with greater overall costs, but there is no statistically significant difference in reconstruction time or rate of surgical procedures. However, a full cost assessment between reconstructive techniques requires a much longer follow-up period.

The retirement rate due to multiple sclerosis has decreased since 1995- A retrospective study in a Finnish central hospital.

BACKGROUND: Multiple sclerosis (MS) is the most common cause of non-traumatic neurological disability affecting young adults during their best working years. Previous studies have shown that approximately two-thirds of patients with MS (PwMS) are unable to retain employment in the long term, and many retire soon after the diagnosis. However, it is not known, how the rate of retirement has changed over the decades, especially after the introduction of disease modifying therapies (DMTs). The year 1995 was selected as a division point because DMTs have been increasingly available ever since. OBJECTIVE: To evaluate the change in retirement rate due to MS and to present risk factors for early retirement. METHODS: A retrospective survey of all PwMS treated at the Department of Neurology, Kanta-Häme Central Hospital, Finland between 1978 and 2015, was conducted. The population was divided into two groups: those diagnosed before year 1995 and those diagnosed thereafter. A Kaplan-Meier analysis was performed to evaluate the time from diagnosis to beginning of a pension in both groups. Crude incidence rates, incidence rate differences as well as age and multivariable adjusted Cox proportional hazard regression analysis were calculated for all pension predictors collected. RESULTS: A total of 484 PwMS were identified, 140 of whom were diagnosed before the year 1995 and 344 after. Actual retirement rates were 88 (63%) before the year the year 1995 and 111 (32%) after, respectively. The hazard for disability pension diminished in PwMS diagnosed after the year 1995 compared to those diagnosed before, HR 0.41 (95% confidence interval 0.31-0.55). The median time from diagnosis to retirement was 8.3 years in the group diagnosed before year 1995 and 11.1 years in the group diagnosed later. Male sex and age were statistically significant risk factors in relapsing-remitting MS, HR for male sex 1.8 (95% confidence interval 1.18-2.75) and for age 1.1 (95% confidence interval 1.07-1.12). Only age was a risk factor in progressive MS with HR 1.09 (95% confidence interval 1.07-1.11). In subgroup of relapsing-remitting MS, not using disease modifying therapies was a statistically significant risk factor, HR 1.89 (95% confidence interval 1.19-3.01). CONCLUSION: The rate of retirement due to MS in Finland has decreased significantly since 1995 and the median time from diagnosis to retirement has become longer. Not using disease modifying therapies for relapsing remitting MS was identified as one risk factor for losing ability to work prematurely.

Predictive risk factors of complications in different breast reconstruction methods.

PURPOSE: Women with different BMI, age and comorbidities seek for breast reconstruction. It is critical to understand the risk associated with each technique to ensure the most appropriate method and timing is used. Outcome after reconstructions have been studied, but consensus is lacking regarding predictive risk factors of complications. The authors present their experience of different autologous and alloplastic reconstructions with an emphasis on predictors of complications. METHODS: Prospectively maintained reconstruction database from 2008 to 2019 was reviewed. Factors associated with complications were identified using logistic regression, multinomial logistic regression and risk factor score to determine predictors of complications. RESULTS: A total of 850 breast reconstructions were performed in 793 women, including 447 DIEP, 283 LD, 12 TMG and 51 implant reconstructions. Complications included minor (n = 231, 29%), re-surgery requiring (n = 142, 18%) and medical complications (n = 7, 1%). Multivariable analysis showed that complications were associated independently with BMI > 30 (OR 1.59; 95% CI 1.05-2.39, p = 0.027), LD technique (OR 4.05; 95% CI 2.10-7.81, p < 0.001), asthma or chronic obstructive pulmonary disease (OR 2.77; 95% CI 1.50-5.12, p = 0.001) and immediate operation (OR 0.69; 95% CI 0.44-1.07, p = 0.099). Each factor contributed 1 point in the creation of a risk-scoring system. The overall complication rate was increased as the risk score increased (35%, 61%, 76% and 100% for 1, 2, 3 and 4 risk scores, respectively, p < 0.001). CONCLUSIONS: The rate of complication can be predicted by a risk-scoring system. In increasing trend of patients with medical problems undergoing breast reconstruction, tailoring of preventive measures to patients' risk factors and careful consideration of the best timing of reconstruction is mandatory to prevent complications and costs.

The rs2516839 variation of USF1 gene is associated with 4-year mortality of nonagenarian women: The Vitality 90+ study.

Upstream transcription factor 1 (USF1) regulates the transcription of many genes related to cell and organism survival processes such as stress and immune response, regulation of cellular senesce, and carcinogenesis. In this study, our aim was to investigate the effect of USF1 single nucleotide variations (SNVs) on longevity in the Vitality 90+ study, a population-based study of nonagenarians (90 ±1 years of age) living in the area of Tampere municipality, Finland. Altogether 509 voluntary nonagenarians (115 males, 394 females) were genotyped using the 5'-nuclease assay for rs2774279G > A, rs2516839T > C, and rs2073658C > T SNVs. During the 4 years of follow-up, the total mortality rate was 64.2%. In the study, we found that the frequency of C-allele of rs2516839 among nonsurviving nonagenarians (52.5%) was higher than those who survived (41.2%; P = 0.0006, odds ratio = 1.575, 95% confidence interval [CI]: 1.215-2.041). Furthermore, carriage of this variation and its haplotypes had a significant gender by genotype interaction (P < 0.05) on mortality. Kaplan-Meier log-rank test during 4-years of follow-up showed significantly higher mortality rate in the case of CC genotype carriage than other genotype carriages in nonagenarian women (P < 0.0001). In addition, after adjusting for age in Cox regression analysis, cardiovascular disease, diabetes, infectious disease, dementia, and living place (nursing home or home), CC genotype of rs2516839T > C was found to be associated with shorter life expectancy in nonagenarian women (hazard ratio = 2.27; 95% CI, 1.34-3.85 P = 0.002). In conclusion, rs2516839 variation and related haplotypes of the USF1 gene are strongly related to all-cause mortality in Finnish nonagenarians, especially among women.

Lateral and Posterior Approaches in Hemiarthroplasty.

PURPOSE: Hemiarthroplasty is a common treatment for patient with a fragility displaced femoral neck fracture. We compared lateral and posterior approaches with respect to need for mobility aids, mobility level, living arrangements, pain, hip dislocation, and survival 12 months after hip fracture. METHODS: A total of 393 fragility femoral neck fracture patients aged 65 years or more who underwent hemiarthroplasty were observed for 12 months. Patient information was collected on admission, during hospitalization, and by telephone interview 1 year after the hip fracture. A total of 269 patients were included in the final analysis. RESULTS: At 1 year after hip fracture, more patients undergoing hemiarthroplasty with the posterior approach (22%) survived without mobility aids compared to those with the lateral approach (12%; p = 0.026). Multivariate logistic regression analysis revealed that the need for mobility aids 1 year after hip fracture was significantly predicted by the use of mobility aids before the fracture (odds ratio = 13.46, 95% confidence interval = 4.29-42.25), age ≥85 years (odds ratio = 3.85, 95% confidence interval = 1.09-13.44), male sex (odds ratio = 3.59, 95% confidence interval = 1.05-12.22), and lateral approach (odds ratio 2.73, 95% confidence interval 1.15-6.50). The posterior approach resulted in four (3.4%) dislocated hips, compared with none by the lateral approach. Survival, mobility level, pain in the operated hip, and living arrangements 1 year postoperatively were not significantly different between groups. CONCLUSION: Hemiarthroplasty using a lateral approach predisposed to the need for ambulatory aids 1 year after hip fracture. The posterior approach, however, predisposed to hip dislocation. Patient selection must be considered when deciding the appropriate surgical approach.

Intellectual disability in children aged less than seven years born moderately and late preterm compared with very preterm and term-born children - a nationwide birth cohort study.

BACKGROUND: Prematurity has been shown to be associated with an increased risk of intellectual disability (ID). METHOD: The aim was to establish whether the prevalence of ID, defined as significant limitations in both intellectual (intelligence quotient below 70) and adaptive functioning among moderately preterm (MP; 32+0 -33+6  weeks) and late preterm (LP; 34+0 -36+6  weeks) infants, is increased compared with that in term infants (≥37+0  weeks). Antenatal and neonatal risk factors for ID among gestational age groups were sought. The national register study included all live-born infants in Finland in 1991-2008, excluding those who died before one year age, or had any major congenital anomaly or missing data. A total of 1 018 256 infants (98.0%) were analysed: very preterm (VP; <32+0  weeks, n = 6329), MP (n = 6796), LP (n = 39 928) and term (n = 965 203). RESULTS: By the age of seven years, the prevalence of ID was 2.48% in the VP group, 0.81% in the MP group, 0.55% in the LP group and 0.35% in the term group. Intracranial haemorrhage increased the ID risk in all groups. Male sex and born small for gestational age predicted an increased risk in all but the MP group. CONCLUSIONS: The prevalence of ID decreased with increasing gestational age. Prevention of intracranial haemorrhages may have a beneficial effect on the neurodevelopmental outcomes of neonates.

Asymptomatic subjects differ less from their twin siblings with MS than from healthy controls in cognitive functioning. A Finnish Twin Cohort study.

BACKGROUND: Cognitive impairment develops in some MS patients at any time during the course of the disease regardless of whether the patients have neurological disability or not. Underlying causes for the MS related cognitive decline are yet poorly understood but both genetic and environmental risk factors have been proposed. OBJECTIVES: To assess whether the cognitive performance differs between subjects with multiple sclerosis (MS) and their asymptomatic co-twins. METHODS: Nineteen twin pairs discordant for MS recruited from the Finnish Twin Cohort were studied neurologically and with a comprehensive neuropsychological test battery. Control group included twenty age and education matched healthy subjects. RESULTS: Compared with the control subjects, the asymptomatic co-twins of MS patients performed significantly less well in tests of naming, verbal reasoning, visuospatial performance, processing speed, attention, verbal memory and learning. The twins with MS performed significantly less well than their co-twins in the SDMT evaluating processing speed, in visual learning and in word fluency. CONCLUSIONS: The lack of significant difference in majority of neuropsychological tests between the MS patients and their co-twins as well as considerable differences between asymptomatic co-twins and healthy controls may suggest that the cognitive performance may be partly developmental and regulated both by genes and shared environmental factors.

Association of nutritional status as measured by the Mini-Nutritional Assessment Short Form with changes in mobility, institutionalization and death after hip fracture.

BACKGROUND/OBJECTIVES: We examined the association of nutritional status as measured by the Mini-Nutritional Assessment Short Form (MNA-SF) with changes in mobility, institutionalization and death after hip fracture. SUBJECTS/METHODS: Population-based prospective data were collected on 472 out of 693 consecutive hip fracture patients aged 65 years and over between January 2010 and December 2012. Declined vs same or improved mobility level, institutionalization and death during the 4-month follow-up were the outcomes. Age, gender, American Society of Anesthesiologists scores, pre-fracture diagnosis of a memory disorder, mobility level, living arrangements and MNA-SF scores at baseline were the independent variables. Age-adjusted and multivariate logistic regression and Cox proportional hazards models were conducted. RESULTS: At baseline, 41 (9%) patients were malnourished and 200 (42%) patients at risk of malnutrition according to the MNA-SF. During the follow-up, 90 (19%) had died. In the multivariate Cox proportional hazards model, malnutrition (hazard ratio 2.16; 95% confidence interval (CI) 1.07-4.34) was associated with mortality. In the multivariate binary logistic regression analyses, risk of malnutrition (odds ratios (OR) 2.42; 95% CI 1.25-4.66) and malnutrition (OR 6.10;95% CI 2.01-18.5) predicted institutionalization. Risk of malnutrition (OR 2.03; 95% CI 1.24-3.31) was associated with decline in the mobility level. CONCLUSIONS: Malnutrition or risk of malnutrition as measured by the MNA-SF were independent predictors of negative outcomes after hip fracture. Patients classified as being at risk of malnutrition by the MNA-SF may constitute a patient population with mild-to-moderate malnutrition and may require specific attention when nutritional interventions are designed after hip fracture.

Long-term effects of toe transfers on the donor feet.

The purpose of this study was to assess the long-term consequences to the donor site of microvascular transfer of one or two toes. This was achieved retrospectively by patient-reported, clinician-based and functional testing. Weight-bearing radiographs were taken of both feet. Seventy-four patients (80 feet, 84 transferred toes) participated in this study. After a median of 16 years follow-up, most patients reported no or only minor complaints concerning the donor site. Cold intolerance and pain during exertion were the most commonly reported complaints. According to the two functional scores used, 92% of patients reported no or minor complaint and 83% of patients received a good result at the donor feet. Maintaining first ray alignment and avoiding early postoperative complications predicted a better outcome. Even though donor site ramifications should be expected after microvascular transfer of toes, patient satisfaction remains high.

Opinions on the counselling, care and outcome of extremely premature birth among healthcare professionals in Finland.

AIM: To study the opinions of paediatric and obstetric personnel on the perinatal treatment and delivery outcome of infants from 22(+0) to 27(+6)  weeks' gestation. METHODS: An email questionnaire was sent to 2963 professionals in 32 maternity hospitals in Finland. RESULTS: The questionnaire survey was completed by 856 (28%) professionals in 30 hospitals. Opinions on outcome were most pessimistic if the infant was very premature. More than a third (37%) assumed no survival at the earliest gestational age, but none dismissed the possibility at 26 weeks' gestation. Paediatric professionals took a more active approach to the treatment of a premature birth and baby than obstetric personnel. Opinions on treatment activity were based firstly on what was best for the baby and secondly on experience. Gynaecologists reported discussing matters regarding premature birth with the parents more often than paediatricians and were much more likely to be influenced by these discussions. CONCLUSION: Paediatric personnel showed a more positive attitude and a more active approach to extremely premature deliveries and babies than obstetric personnel. There would appear to be some inconsistency between prenatal counselling and treatment activity after birth at the limit of viability.

Are body mass index, waist circumference and waist-to-hip ratio associated with leptin in 90-year-old people?

Data on how body mass index (BMI), waist circumference (WC) and waist-to-hip ratio (WHR) are associated with body fat in the oldest-old people are scarce. The purpose of this study was to examine if BMI, WC or WHR are associated with leptin, a biological surrogate measure of body fat in 90-year-old people. The data comes from the Vitality 90+ Study, a prospective population-based study of people living in Tampere, Finland. BMI, WC, WHR and plasma concentration of leptin were available for 160 women and 54 men aged 90 years. BMI and WC had a strong significant positive association with leptin both in women and in men, but WHR was associated with leptin only in men. In conclusion, based on the circulating level of leptin, BMI and WC, and WHR in men, reflect body fat in 90-year-old people, but WHR seems to be a poor indicator of body fat in 90-year-old women.

Obstetric parameters and Doppler findings in cerebral circulation as predictors of 1 year neurodevelopmental outcome in asphyxiated infants.

OBJECTIVE: To establish the association of cardiotocography (CTG) and other obstetric parameters with pulsed Doppler findings in cerebral arteries during the first day of life, and to compare the cerebral artery Doppler with other determinants of asphyxia in predicting 1-year neurological outcome in asphyxiated full-term infants. STUDY DESIGN: Cerebral blood flow velocity (CBFV) were measured from the anterior cerebral (ACA) and basilar (BA) arteries in 30 asphyxiated and 30 healthy-term infants using pulsed Doppler ultrasonography at approximately 24 h of age. CTG, cord artery pH, Apgar scores, biochemical asphyxia markers and symptoms of hypoxic-ischemic encephalopathy (HIE) were compared with the Doppler findings in respect of the ability to predict the outcome, defined by death or impaired neurological performance at 1 year of age. RESULT: In all, 20% of the asphyxiated infants but none in the control group had increased peak systolic CBFVs (mean+3 s.d.) in the ACA or BA. The sensitivity of increased systolic CBFV to predict abnormal outcome in the asphyxia group was 83%, specificity 95% and the sensitivity of the combination of HIE grade from 2 to 3 and increased systolic CBFV in the ACA or BA was 100% and specificity was 95%, respectively. Pathological CTG and low cord artery pH or low Apgar scores showed low predictive power. CONCLUSION: Grade from 2 to 3 HIE and the systolic CBFV (mean+3 s.d.) in the ACA or BA by Doppler ultrasound seemed to predict the outcome in asphyxiated infants at 1 year of age better than CTG, acid basement status, Apgar scores or asphyxia markers. If an increase of more than +3 s.d. in the systolic CBFV does not occur within the first 24 h of life, a good 1-year neurological outcome may be anticipated.

Preschool asthma after bronchiolitis in infancy.

Asthma risk is lower after wheezing associated with respiratory syncytial virus (RSV) than with non-RSV infection in infancy. RSV is the main wheezing-associated virus in infants aged <6 months. We evaluated the outcome of children hospitalised for bronchiolitis at <6 months of age, with special focus on viral aetiology and early risk factors. Out of 205 infants hospitalised for bronchiolitis at <6 months of age, 127 (62%) attended a control visit at a mean age of 6.5 yrs and the parents of an additional 39 children were interviewed by telephone. Thus, follow-up data collected by identical structured questionnaires were available from 166 (81%) children. Viral aetiology of bronchiolitis, studied on admission by antigen detection or PCR, was demonstrable in 97% of cases. Current asthma was present in 21 (12.7%) children: 8.2% in the 110 former RSV patients versus 24% in non-RSV patients (p=0.01). 45 (27%) children had ever had asthma. In adjusted analyses, atopic dermatitis, non-RSV bronchiolitis and maternal asthma were independently significant early-life risk factors for asthma. The risk of asthma was lower after RSV bronchiolitis than after bronchiolitis caused by other viruses in children hospitalised at <6 months of age.

Adoption of an Internet-based patient education programme in psychiatric hospitals.

Internet-based patient support systems are widely assumed to predict a future trend in patient education. Coherent information is still lacking on how patient education is adopted in psychiatric hospitals and how information technology is used in it. Our aim was to describe nurses' adoption of an Internet-based patient education programme and the variables explaining it. The study was based on Rogers' model of the diffusion of innovation. The Internet-based patient education sessions were carried out by nurses on nine acute psychiatric inpatient wards in two Finnish hospitals. They were evaluated with reports and analysed statistically. Out of 100 nurses, 83 adopted the programme during the study period. The nurses fell into Rogers' groups, late majority (72%), laggards (17%), early majority (7%), early adopters (3%) and innovators (1%). Three groups were formed according to their activity: laggards, late majority, adopters (including early majority, early adopters, innovators). There was a statistical difference between the nurses' programme adoption between the two hospitals (P= 0.045): more laggards (65% vs. 35%) and adopters (73% vs. 27%) in the same hospital. The findings help to provide insight into the contexts and settings when adopting information technology programmes in the area of mental health care.

Long-term functional results of microvascular toe-to-thumb reconstruction.

The purpose of this study was to evaluate the long-term functional results of microvascular toe-to-thumb reconstruction after trauma. Forty-one patients meeting the inclusion criteria were available for a clinical follow-up study. The function of the hand was assessed with questionnaires as well as with modified Tamai and Sollerman hand function tests. According to the questionnaires, most activities were considered easy or quite easy and the majority of the patients (36/41) managed with no or minor complaints. Clinical tests showed good recovery of function. Patient satisfaction was high. There were superficial infections in five hands and in six donor feet. In total, 16 late corrective operations were done to eight patients. Microvascular toe transfer is a good option for grip reconstruction after thumb amputation. The extent of the initial injury influences the achievable outcome, yet even a single toe transfer can restore adequate grip function.

Lifestyle factors and varicose veins: does cross-sectional design result in underestimate of the risk?

OBJECTIVES: To assess whether smoking, alcohol drinking and dietary factors are linked with varicose veins. METHODS: A middle-aged general population of 4903 was studied, and prevalence rates at entry and five-year incidence of varicose veins were assessed. Lifestyle habits were recorded at entry and at the end of the follow-up. RESULTS: New varicose veins were significantly more common in individuals with regular alcohol intake, incidence odds ratio (OR) 1.5 (95% confidence interval [CI]: 1.05-2.3) in a multivariate analysis (of 2202 individuals). The association was particularly strong in women. Smokers had a higher incidence of varicose veins compared with non-smokers, OR 1.3 (95% CI: 0.9-1.8), but without statistical significance. Having daily meals of meat implied less new varicose veins than having 0-2 weekly meals of meat. CONCLUSION: Alcohol was likely to increase the risk of varicose veins in women and smoking in both genders. These findings were seen in the follow-up design, but not when the data of these risk factors were compared with varicose veins prevalent at entry.

Asthma Programme in Finland: Did the use of secondary care resources become more rational?

OBJECTIVES: The aims were to evaluate the profile of newly diagnosed adult asthma cases and the approach adopted to the secondary care management at the launch of the Finnish asthma programme in 1994 and seven years later, in 2001. METHODS: A retrospective medical record audit was made of non-acutely referred patients with asthma in 1994 (n=165) and in 2001 (n=133). Clinical profile data, numbers of out-patient visits and periods of in-patient care before and after asthma diagnosis were gathered from referral letters and secondary care records. RESULTS: The newly diagnosed asthma patients in 2001 were older, more obese and had more co-morbidities. The main asthma symptoms, such as dyspnoea, wheezing and cough, occurred equally in both years but were more often periodic than daily in 2001. Wheezing during auscultation was significantly less common in 2001. The diagnostic process was associated to a history of asthma in first-degree relatives (OR 5.34, 95% CI 1.12-24.49) in 1994 and a visit to a nurse prior to that to a physician (OR 3.13, 95% CI 1.17-8.37) in 2001. Secondary care visits per new case of asthma (7.3 in 1994 vs. 5.4 in 2001) and days in hospital (3.6 in 1994 vs. 0.95 in 2001) decreased significantly. CONCLUSIONS: The profile of asthma diagnosed in secondary care indicates milder disease with more co-morbidities in 2001 than in 1994.Trends towards assigning a more active role on the part of primary care physicians and more rational use of secondary care resources in the management of asthma were found.

Breast magnetic resonance imaging findings in women treated with toremifene for premenstrual mastalgia.

BACKGROUND: Toremifene, a selective estrogen receptor modulator, has been shown to be effective in alleviating premenstrual breast pain. However, the exact mechanism by which toremifene and related compounds work in premenstrual mastalgia is poorly understood. PURPOSE: To find out if the effect of toremifene on breast would be detectable with dynamic magnetic resonance imaging (MRI). MATERIAL AND METHODS: This randomized, double-blind crossover study was performed on women suffering from marked premenstrual mastalgia. Ten women were randomized to receive either toremifene (20 mg) or placebo from cycle day 15 until next menstruation for three menstrual cycles. After a washout period, the treatment was crossed over for three additional cycles. The MRI evaluations were performed premenstrually at the end of each treatment phase. Breast pain and quality-of-life scores were collected from one baseline cycle and from all the treatment cycles. RESULTS: Nine patients were evaluable for this analysis. Both the enhancement ratio and the maximum slope of enhancement tended to be smaller during the toremifene cycles as compared to placebo. On the left side, the difference in the maximum slope of enhancement between toremifene and placebo was statistically significant (median 5.150 [range 3.7-6.7] and 6.500 [range 4.9-9.5], respectively; P=0.047). T2 relaxation times as well as breast pain and quality-of-life scores were inconsistent. CONCLUSION: Use of toremifene is associated with measurable changes in dynamic breast MRI findings in women with cyclic breast pain.
