Knowledge, attitude and preventive practices for breast cancer among health care professionals at Aga Khan Hospital Karachi

OBJECTIVE: To assess the knowledge and practice of risk factors, symptoms and screening for breast cancer among health care professionals. METHODS: A cross sectional study was carried out at The Aga Khan University Hospital from January 2008 to March 2008. A total of 336 health care workers including consultants (48), fellows (17), residents (76), medical officers (14), interns (37), nurses (94) and fourth and final year medical students (50) were requested to fill a questionnaire designed to assess the knowledge about the risk factors, signs and symptoms, screening tools, breast self examination (BSE) and treatment. RESULTS: More than two third participants had good knowledge about the risk factors and signs of breast cancer except some dissociation regarding association of menarche status and smoking. Majority was aware of the benefits of mammography. More than 80% had the consensus that breast cancer is curable if detected early and more than 50% thought that a surgeon should be consulted first if lump is palpable. CONCLUSIONS: This study reveals that health care professionals have fairly good awareness regarding the risk factors, symptoms and role of mammography. But some are still deficient in their knowledge regarding screening modalities and BSE method and time and role of chemotherapy. And this can be improved with further education

Pathogenesis, diagnosis and management of primary melanoma of the colon

<p>Abstract</p> <p>Background</p> <p>Melanomas within the alimentary tract are usually metastatic in origin. On the other hand, primary melanomas of the gastrointestinal tract are relatively uncommon. There are several published reports of melanomas occurring in the esophagus, stomach, small bowel, and anorectum. The occurrence of primary melanoma of the colon has, however, only been rarely reported. The optimum modus operandi for the management of primary colonic melanoma remains nebulous due to the limited number of reports in literature.</p> <p>Methods</p> <p>A comprehensive search of Medline, Cochrane and Highwire was performed using the following keywords: 'melanoma', 'malignant melanoma', 'primary melanoma', 'colon', 'gastrointestinal tract', 'alimentary tract', 'digestive tract', and 'large bowel'. All patients with primary melanoma localized to the colon were included in the review. Patients with metastatic melanomas to the gastrointestinal (GI) tract and primary melanomas localized to the GI tract in anatomic locations other than colon were excluded.</p> <p>Results</p> <p>There have been only 12 reported cases of primary melanoma of the colon to date. The average age of patients on presentation was 60.4 years without any significant gender predilection. Right colon (33%) and cecum (33%) were the most common sites for the occurrence of primary colonic melanoma while abdominal pain (58%) and weight loss (50%) were the most common presenting complaints. Colonoscopy is the most reliable diagnostic investigation and offers the additional advantage of obtaining tissue for diagnosis. S-100 and HMB-45 are highly sensitive and specific for the diagnosis of this malignancy. For primary colonic melanomas that have not metastasized to any distant parts of the body, surgical resection with wide margins appears to be the treatment of choice. Although the management was individualized in every case, most of the authors preferred traditional hemicolectomy as the favored surgical approach. Chemotherapeutic agents including interferons, cytokines, biological agents and radiation therapy for brain metastases have been reported as adjuvant and palliative options while considering malignant melanomas in general. The average recurrence-free interval was 2.59 years. Nine of the 12 reports documented follow-up in their patients. Two of these 9 (22.2%) patients died.</p> <p>Conclusions</p> <p>Primary melanoma of the colon is a rare clinical entity. Whenever a seemingly primary melanoma is detected in an atypical location such as the colon, it is prudent to conduct a thorough clinical investigation to consider the possibility of metastatic disease. Further studies are needed to document the long term follow-up, survival advantage and safety of the management approaches employed in patients with primary colonic melanoma. Based on current data, surgical resection appears to be appropriate management for primary colonic melanomas; unless the disease has metastasized to distant sites where surgery may have a limited palliative role.</p

Perception and practices of breastfeeding of infants 0-6 months in an urban and a semi-urban community in Pakistan: a cross-sectional study

OBJECTIVE: To investigate mother\u27s perception and practices about breastfeeding and their socio-demographic correlate in infants equal to or less than 6 months. METHODS: A cross-sectional study was carried out on 200 mother-infant pairs who visited the health care centers, Bilal Colony (semi-urban) and the Aga Khan University (urban), for their well baby follow-ups and vaccination using convenient sampling. Frequencies and percentages were computed and Chi-square was used to find associations between socio-demographics of mothers and their perception and practices about breastfeeding. RESULTS: Exclusive breastfeeding was reported by about 54% of the mothers. Thirty-five percent of the mothers gave prelacteal feed, 14% discarded colostrum and 43% woke up their infant to feed if time had exceeded 2 hours. Majority of the females were aware of the advantages (92%) and the disadvantages (85%) of breastfeeding. However, the awareness of positive feedback relationship of milk production and sucking was lacking and breast feeding was considered to cause weakness in mothers. CONCLUSION: Despite the efforts of health policy makers, the results show a situation that is not improving. Women were aware of the advantages and disadvantages of breast and bottle feeding but a disparity was observed between their perception and practices
