Enormous progresses have been made in recent years for the involvement of nervous system in particular the vagus nerve in inflammatory responses. The parasympathetic nerve can be activated by “inflammatory reflex” to inhibit macrophages, via their specific nicotinic receptor ?-7 subunit, and hence to reduce the production of tumor necrosis factor (TNF) that plays a pivotal role in many inflammatory reactions and is a key mediator for septic shock. This cholinergic anti-inflammatory pathway has been utilized, with positive outcomes, by means of either pharmacological or electrical stimulation in animal models against inflammatory responses and septic shock. Monoclonal antibodies against TNF and other pro-inflammatory cytokines have also been developed and used against inflammation experimentally and clinically. Although clinical use of these new treatments have yielded primitive and only limited results, these new research findings and concepts are important for the advance of modern medicine, as well as for better comprehension of some theories and practices in traditional medicine. Future directions are discussed herewith. [

Four hundred and nineteen articles related to breast cancer were found in a search through a database dedicated to indexing all original data relevant to medicine published in Malaysia between the years 2000-2013. One hundred and fifty four articles were selected and reviewed on the basis of clinical relevance and future research implications. Overall, Malaysian women have poor survival from breast cancer and it is estimated that half of the deaths due to breast cancer could be prevented. Five-year survival in Malaysia was low and varies among different institutions even within the same disease stage, suggesting an inequity of access to optimal treatment or a lack of compliance to optimal treatment. Malaysian women have poor knowledge of the risk factors, symptoms and methods for early detection of breast cancer, leading to late presentation. Moreover, Malaysian women experience cancer fatalism, belief in alternative medicine, and lack of autonomy in decision making resulting in delays in seeking or avoidance of evidence-based medicine. There are ethnic differences in estrogen receptor status, HER2 overexpression and incidence of triple negative breast cancer which warrant further investigation. Malay women present with larger tumours and at later stages, and even after adjustment for these and other prognostic factors (stage, pathology and treatment), Malay women have a poorer survival. Although the factors responsible for these ethnic differences have not been elucidated, it is thought that pharmacogenomics, lifestyle factors (such as weight-gain, diet and exercise), and psychosocial factors (such as acceptance of 2nd or 3rd line chemotherapy) may be responsible for the difference in survival. Notably, survivorship studies show self-management programmes and exercise improve quality of life, highlighting the need to evaluate the psychosocial impact of breast cancer on Malaysian women, and to design culturally-, religiously- and linguistically-appropriate psycho-education programmes to help women cope with the disease and improve their quality of life. Research done in the Caucasian populations may not necessarily apply to local settings and it is important to embark on local studies particularly prevention, screening, diagnostic, prognostic, therapeutic and psychosocial research.

In-utero intestinal volvulus is a rare but potential life threatening foetal complications. It is a surgical emergency and delay in diagnosis or treatment can increase the morbidity and mortality to the foetus. We report a case of mild foetal bowel dilatation diagnosed at 21 weeks of gestation. She was closely follow up and at 31 weeks of gestation, in-utero intestinal volvulus was diagnosed with the characteristic ‘whirlpool’ sign on ultrasound examination. This case emphasises the importance of early recognition and quick decision to delivery when intestinal volvulus is diagnosed. This enabled early surgical intervention to prevent further foetal morbidity.

Background: Breast cancer is becoming more important in Asia since it affect the younger age group. Question arises whether it is safe for breast lesions to be left in-situ if all the elements in triple assessment are benign. The aim of this study is to audit all the excision biopsies of breast lumps done in the University Malaya Medical Centre (UMMC), to review the association of age with the type of pathological finding and to evaluate the rate of carcinoma in these biopsies. Methods: We conducted a retrospective study of all women who had excision biopsy of a breast lump in the University Malaya Medical Centre from January 2005 to December 2006. All patients with malignant preoperative biopsies were excluded. Results: Of 717 lesions in 664 patients, 459 (64%) were fibroadenoma, 114 (15.9%) were fibrocystic disease, 20 (2.8%) were phylloides tumour, 27 (3.8%) were papilloma, 59 (8.2%) were malignant and 38 (5.3%) were of other pathology. Of the 717 open biopsies, 449 (62.6%) had fine-needle aspiration cytology (FNAC), 31 (4.3%) had core needle biopsy (CNB), while 14 (2.0%) had both FNAC and CNB done prior to excision biopsy. 251 (35%) had neither FNAC nor CNB. The incidence of fibroadenoma decreased with increasing age and the incidence of fibrocystic changes and papilloma increased with increasing age. There was no association of age with phylloides tumour. The incidence of unexpected malignancy increased with increasing age. The incidence rates were 0.3%, 4.5%, 19.4%, 29.7% and 29.6% for the age group below 30, 30-39, 40-49, 50-59 and above 60 years of age respectively. Of the 59 malignant lesions, FNAC was performed on 47 (79.7%) and CNB on 16 (27.1%). 9 had both FNAC and CNB and 3 had neither FNAC nor CNB. Out of the 56 lesions where FNAC/CNB were done, 23 (41.1%) were reported as benign, 20 (35.7%) as suspicious, 4 (7.1%) as atypical, 5 (8.9%) as inadequate, 2 (3.6%) as equivocal and 2 (3.6%) as lymphoid lesions. Out of the 23 prior biopsies reported as benign, 22 were in the age group above 40. Conclusions: In conclusion, the rate of unexpected malignancy in open biopsies increases with age. It is recommended that all women above the age of 40 presenting with a palpable breast lump or a suspicious non-palpable abnormality on screening mammogram to have their lump excised even though the lump is benign on FNAC or CNB. However, women age of 30 to 39 should also have the lump excised in the presence of other risk factors such as family history of breast cancer.

In this study, tumorspheres were generated from TW06 nasopharyngeal carcinoma cell line and examined their expression of putative cancer stem-like cell surface markers and drug sensitivity. The rate of tumorsphere expansion from dissociated late passage TW06 tumorspheres (≥ passage 15) was higher than that from parental cells and dissociated 10-day-old (passage 0) tumorspheres. The expression of CD24 surface marker was lost in the generation of tumorspheres and the loss was reversible after differentiating the tumorspheres in monolayer culture conditions. Drug sensitivity assay showed that late passage tumorspheres were resistant to docetaxel and oxaliplatin treatment. Our data suggest that serially passaged tumorspheres possess the characteristics of CSCs that render them a suitable preclinical in vitro model for evaluating anticancer drug efficacy and elucidating the underlying mechanisms of drug resistance.

Background: Immortalized human endothelial cells are widely used as in vitro models for debilitating conditions such as cancer, cardiovascular and ocular diseases. Human microvascular endothelial cell (HMEC-1) is immortalized via stable transfection with a gene encoding SV40 large antigen whilst telomerase-immortalized human microvascular endothelial (TIME) cells is immortalized by engineering the human telomerase catalytic protein (hTERT) into primary microvascular endothelial cells. Here, we established a three-dimensional (3D) spheroid invasion assay with HMEC-1 and TIME and compared the difference in their ability to invade through the collagen matrix in response to exogenous growth factors, namely vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF). Methods: TIME and HMEC-1 spheroids were embedded in a collagen matrix. The spheroids were stimulated with exogenous growth factors, namely VEGF (50ng/mL) and bFGF (200ng/mL). Twelve points of invasion length from a spheroid was measured using image analysis software, Image J. Three independent experiments were conducted and data was analysis by GraphPad Instat software, version 3.05. Results: TIME spheroid invasion was 16.5 fold higher with exogenous VEGF (50ng/mL) and bFGF (200ng/mL) treatment as compared to those cultured in complete growth medium only. In contrast, no significant difference was observed between HMEC-1 spheroids stimulated with and without exogenous growth factors, VEGF and bFGF. Conclusions: This is the first report on the establishment of a 3D-spheroid invasion assay with TIME cells. The requirement of VEGF and bFGF for TIME spheroids invasion is a novel finding. In addition, this assay offers an advantage over HMEC-1 for testing novel angiogenic agents since it is not affected by endogenously secreted growth factors.

This study validates The Malay Version of The Inventory of Socially Supportive Behaviour. Methods: The psychometric properties of the ISSBMalay Version were examined on sixty-eight women who were Malay native speakers and diagnosed with breast cancer. Respondents answered the questionnaire at three weeks and ten weeks following surgery for breast cancer. Results: The Malay Version of ISSB showed excellent internal consistency (Cronbach’s alpha=0.96). Test-retest Intraclass Correlation Coefficient (ICC) was 0.03. Small mean differences were observed at test-retest measurement with Effect Size Index 0.18. Conclusion: The Malay Version of the ISSB could be an appropriate tool to measure the supportive behavior of the Malaysian population.
