The therapeutic dilemma of idiopathic granulomatous mastitis.

INTRODUCTION: Idiopathic granulomatous mastitis (IGM) is a rare, benign, chronic breast condition that can cause repeated abscesses or mass formation in bilateral breasts. The condition can severely impact the quality of life of affected women. This study aims to evaluate effective treatment modalities, as well as understand the demographics and clinical presentation of patients with IGM. METHODS: An 11-year retrospective review was performed of patients diagnosed with IGM from 1 January 2008 to 31 December 2018 at a tertiary breast unit. RESULTS: A total of 77 patients were included in the study. The median age at presentation was 36 years old. IGM presented most commonly as a breast lump (98.1%). The median number of flares was 2 (1-12). Of the 77 patients, 68.8% (53) were treated with antibiotics, 50.6% (39) with steroids, and 44.2% (34) underwent surgery, in the course of their IGM treatment. Forty-five (59.2%) of the 76 patients with IGM required a multimodal treatment approach to achieve remission. There was no significant difference in the number of flares no matter the initial treatment (P=0.411), or subsequent treatment modality (P=0.343). Smokers had 10 times greater odds of having a "high flare" of IGM compared to those who did not smoke (P=0.031, odds ratio 10.444, 95% confidence interval 1.092-99.859). CONCLUSION: IGM is a clinical diagnosis. It is a rare, relapsing breast inflammatory condition that affects young females with no superior treatment modality. Smoking is associated with higher number of flares of IGM and should be discouraged in IGM patients.

Understanding the Psychosocial Needs of Women who Present with Advanced Breast Cancer.

INTRODUCTION: Advanced breast cancer (ABC) remains common in Singapore. In 2019, 22.1% of breast cancer patients presented with ABC in our institution. Despite increasing affluence and the advent of national mammographic screening, the incidence of ABC has not changed significantly. This suggests inherent differences in women who present late. We aim to explore the socio-economic background, knowledge and attitudes of women who present with ABC. METHODS: Between December 2013 and July 2015, 100 patients who presented consecutively with ABC in a tertiary institution in Singapore were recruited to participate in an interviewer-led questionnaire exploring psychosocial and economic issues. RESULTS: Among the 100 patients, 63 and 37 presented with stages 3 and 4 breast cancer respectively. Median age was 57 (27-86), 52% had at least secondary education, 53% had no formal employment and 71% were married; 88% were aware of breast cancer symptoms, 82% were aware that mammography can help detect cancer, 82% believed that current treatment modality for breast cancer is effective, 96% had never undergone a mammography and 52.9% felt mammograms were unnecessary. A total of 64% presented symptomatic from the breast tumour, with a median duration of 3 months. Many of the patients were aware of breast cancer symptoms and the utility of mammography. However, a group of patients did not comply with screening. This may be due to poor understanding about breast screening and detection in its asymptomatic phase. CONCLUSION: Further public education to improve understanding of breast cancer and screening mammography may help to improve rates for earlier detection of breast cancer.

The Changing Epidemiology of Serious Trauma in the Elderly Population: An Increasing Concern of a Tertiary Hospital in Singapore.

INTRODUCTION: Although trauma is often seen in the young, there is a recent shift in this trend as more elderly patients are hospitalised for traumatic injuries. This study examined serious trauma in young and elderly patients and hypothesised that the increase in incidence of elderly serious trauma has led to greater burden of care in hospitals and health services. MATERIALS AND METHODS: Details of trauma patients admitted with an Injury Severity Score ≥9 or to the intensive care unit or high dependency unit of a tertiary acute hospital between 2004 and 2015 were retrospectively reviewed. Patients ≥65 years old who sustained low-impact trauma that resulted from same-level falls with isolated hip fractures or compression fractures of the vertebral column were excluded. Patients were classified as either elderly (≥65 years old, n = 5074) or young (<65 years old, n = 9088) and their baseline characteristics, complications rate and length of hospital stay were evaluated. RESULTS: Elderly patients ≥65 years old accounted for 51.2% of seriously injured patients after 2014 and their numbers are increasing at an annual rate of 16.5%. They also experienced longer hospital stay in the general ward than younger patients. CONCLUSION: The number of elderly trauma patients were thrice that of all trauma patients seen and they also required longer hospitalisation. This trend has led to greater burden of care in hospitals and health services in Singapore.

Majority of flat epithelial atypia diagnosed on biopsy do not require surgical excision.

BACKGROUND: Borderline risk lesions such as flat epithelial atypia (FEA) are increasingly being diagnosed on biopsy. The need for surgery is being debated. In this study, we determined the frequency of histological upgrade following a diagnosis of FEA on biopsy and evaluated potential predictive factors. METHODS: Retrospective review was done of 194 women who underwent biopsy of indeterminate lesions (total 195 lesions) that were diagnosed as FEA. The review covered a 10-year period. Cases where malignancy was also present together with FEA within the same biopsy cores were excluded. RESULTS: Lesions diagnosed as FEA on biopsy were mostly asymptomatic and presented as microcalcifications on mammogram. Flat epithelial atypia was the only abnormality detected in one-third of cases, was associated with a benign or another borderline lesion in another third and was associated with atypical ductal hyperplasia (ADH) in another third. Six patients (3.1%) were later found to have ductal carcinoma-in-situ (DCIS) at surgery. The presence of ADH in the biopsy was the only predictor of histological upgrade to malignancy (P = 0.04, OR 11.24, 95% CI 1.10 - 115.10), and was present in 5 of the 6 patients. Surgery was advised in the last patient because of radiology-pathology discordance. Thirty-six lesions (18.5%) were not excised and no interval progression or malignancy was found on follow up. CONCLUSION: Histological upgrade to malignancy was uncommon in lesions found on biopsy to be FEA. Non-operative management of biopsy-proven FEA can be considered in the absence of ADH and radiology-pathology discordance.

Pulmonary Vein Pseudoaneurysm Secondary to Blunt Trauma: A Novel Management Strategy.

Traumatic pulmonary vein pseudoaneurysm is an extremely rare condition that is challenging to manage. We present a unique case of a pulmonary vein pseudoaneurysm from blunt trauma in a patient with previous ipsilateral decortication. The patient was treated with percutaneous transparenchymal access to the pulmonary vein pseudoaneurysm.
