Help-seeking patterns in Chinese women with symptoms of breast disease: a qualitative study.

BACKGROUND: Prompt utilization of health services on detecting breast symptoms can improve breast cancer (BC) survival. Little is known about Chinese women's help-seeking behaviour. Our aim was to determine patterns of self-referral among Hong Kong Chinese women with self-detected breast symptoms. METHODS: We recruited 37 women awaiting their first consultation at public hospitals for breast symptoms. Interviews were transcribed and analysed based on the grounded theory approaches. RESULTS: A two-stage help-seeking model provided the best interpretation of the data. Symptom recognition was triggered by symptom interpretation, symptom progression and social messages. Painful lumps were seen as symptomatic, but atypical symptoms were often dismissed as benign as they responded to dietary change. Symptom intensification and discussions with someone who had faced BC prompted consultation. Service utilization involved fear of consequences, confirmation need, symptom distress, lay referral, media prompts and opportunistic presentation. Fearing cancer as incurable delayed consultation. Utilization barriers included cost, uncertainty about referral pathways, competing priorities and embarrassment. CONCLUSIONS: Atypical and painless presentation was more common among women delaying presentation. Barriers included cost, access, time and embarrassment. Education should emphasize atypical symptoms, the high-cure rate and the need for early presentation. Reduced cost and improved access to clinics would enhance early consultation.

Foreign body ingestion: comparison of diagnostic accuracy of computed tomography versus endoscopy.

PURPOSE: To investigate and compare the sensitivity and specificity of computed tomography and of endoscopy, as diagnostic tests for foreign body ingestion. MATERIALS AND METHODS: Over a two-year period, Asian patients with suspected foreign body ingestion were studied. The clinical findings, computed tomography images, endoscopic results, treatment and outcomes were prospectively analysed. RESULTS: Over the study period, 193 patients were admitted for foreign body ingestion, complaining of a persistent foreign body sensation in the neck. The sensitivity and specificity of computed tomography were 78 and 96 per cent, respectively; the positive predictive value was 75 per cent and the negative predictive value 97 per cent. The diagnostic accuracy of computed tomography was 94 per cent. CONCLUSION: Our study showed that computed tomography had high negative predictive value and accuracy in the diagnosis of foreign body ingestion. It was useful if endoscopy showed negative findings but the patient still had persistent symptoms of foreign body ingestion.

Clinical and pathological characteristics of Chinese patients with BRCA related breast cancer.

Breast cancers related to BRCA mutations are associated with particular biological features. Here we report the clinical and pathological characteristics of breast cancer in Chinese women with and without BRCA mutations and of carriers of BRCA1 mutations compared to BRCA2 mutations. Two hundred and 26 high-risk Hong Kong Chinese women were tested for BRCA mutations, medical information was obtained from medical records, and risk and demographic information was obtained from personal interviews. In this cohort, 28 (12.4%) women were BRCA mutation carriers and among these carriers, 39.3% were BRCA1 and 60.7% were BRCA2 mutations. Mutation carriers were more likely to have a familial history of breast and ovarian cancer, high-grade cancers, and triple negative (TN) cancers. Prevalence of TN was 48.3% in BRCA carriers and 25.6% in non-carriers and was 67.7% in BRCA1 and 35.3% in BRCA2 carriers. Estrogen receptor (ER) negative cancer was significantly associated with BRCA1 mutations, especially in those under 40 years of age. BRCA-related breast cancer in this Chinese population is associated with family history and adverse pathological/prognostic features, with BRCA2 mutations being more prevalent but BRCA1 carriers having more aggressive and TN cancers. Compared to Caucasian populations, prevalence of BRCA2 mutations and TN cancer in BRCA2 mutation carriers in Chinese population are elevated.

Microbial contamination of femoral head allografts.

OBJECTIVE: To study the incidence of microbial contamination at the bone bank of the United Christian Hospital. DESIGN. Retrospective study. SETTING: Regional hospital, Hong Kong. PATIENTS: A total of 151 patients (33 men and 118 women) who underwent hip arthroplasty surgery and from whom femoral head allografts were retrieved between January 1994 and March 2000; and 81 patients in whom allografts were implanted. MAIN OUTCOME MEASURES: Bone biopsies were taken from the femoral head and used to detect any microbial contamination that might have occurred during removal and after storage. The rates of infection among recipients and donors were also assessed. RESULTS: Of the 151 allografts, 94 non-contaminated allografts were implanted by the end of the study. Fourteen (9.3%) heads showed positive culture results after retrieval and were discarded. Four (4.3%) of the 94 stored allografts that were implanted tested positive for microbial growth, but the recipients of these allografts did not develop any clinical infection. Three (3.2%) had wound infections after implantation of the stored allografts although the grafts had previously been tested negative for any microbial contamination. CONCLUSION: Our centre has a low allograft contamination rate. The wound infection rate among recipients was also low. The culture of a bone biopsy sample is a reliable method to detect contamination of bone grafts. However, the contamination rate among stored allografts should prompt orthopaedics departments to review allograft handling procedures, so as to minimise the chance of contamination.
