Background: Sialendoscopy is gaining in popularity in treating calculus disease. The delicacy of the instrument and the diameter of the salivary ducts are factors that limit the ability to achieve complete success. There is also continued speculation regarding the utility of the procedure, especially among clinicians who are masters of conventional methods like sialadenectomy and sialodochotomy. Objective: To assess the efficacy of sialendoscopy over conventional methods in treating sialolithiasis. Methods: A prospective case control study was conducted in a tertiary care centre; this study involved 50 patients of sialolithiasis, and it extended over a 36-month period. All had undergone treatment, either by conventional methods or interventional sialendoscopy. All patients with nonpalpable calculi smaller than 6 mm underwent interventional sialendoscopy. Failed sialendoscopies and larger nonpalpable calculi were removed through sialadenectomy. The outcome variables studied included calculus removal, postoperative symptoms, and gland preservation. Results: The success rate in terms of calculus removal by sialendoscopy was 88%, versus 100% by sialadenectomy. The salivary gland was preserved in 88% of the cases in the sialendoscopy group. Only 12% of patients were symptomatic. Conclusion: Sialendoscopy was effective in removing calculi of various sizes; it was definitely superior to conventional methods. Sialadenectomy should be reserved for cases either not suitable for sialendoscopy or in which there was an intervention failure.

The incidence of cancer in Malaysia is rising alarmingly and newly qualified doctors will be expected to be competent in the basic management of cancer patients. However, the opportunity to gain experience in oncology management will remain limited unless these students are stationed in an oncology unit which is solely dedicated to the treatment of such patients. Therefore, it is essential that undergraduate medical school training equips students with a sound knowledgebase, so that they can confidently manage basic oncological conditions appropriately. With the many private and local medical universities across the country, it is important that oncology training be standardized and reflective of the local resources available, and government health policies. As a result, having a standardized curriculum would help create a framework whereby competencies in cancer management would be accurately assessed.

ith recent medical advances and the availability of newer sophisticated technologies, critically ill patients tend to survive longer. 1 Thus, decisions to forgo life-sustaining medical treatment generate challenging issues that all doctors must face. 2 The aim of this pilot study was to assess attitudes towards end-of-life care in ICU which included futile therapy (withholding and withdrawing therapy) among final year medical students who had received the same degree of clinical exposure and training in medical school. The results revealed varying attitudes and views towards end-of-life care in ICU suggesting other factors such as religion, ethnicity and culture may influence decision making

Acute myeloid leukaemia (AML) is one of the fatal haematological malignancies as a consequence of its genetic heterogeneity. At present, the prediction of the clinical response to treatment for AML is based not only on detection of cytogenetic aberrations but also by analysing certain molecular genetic alterations. There are limited in sights into the contribution, disease progression, treatment outcome, and characterisation with respect to the uncommon chromosomal abnormalities leading to AML. Here, we describe the clinical, morphological, cytogenetic, and mutational findings of a 52-year-old female patient with AML without maturation (AML-M1). Conventional karyotyping and spectral karyotyping (SKY) were done on metaphase chromosomes from bone marrow cells at the time of diagnosis. A mutation analysis was performed on the hotspot regions of various genes, including FLT3, CEBPA, NPM1, RAS, c-KIT, IDH1 and IDH2. Cytogenetic and mutation analyses revealed a novel translocation, t(X;2)(q28;p22), with both NPM1 and IDH1 mutations. To the best of our knowledge, the presence of both NPM1 and IDH1 mutations in t(X;2) (q28;p22) is a novel finding in AML.

Background: At the International Medical University (IMU), a half day cardiac life support teaching session was provided to fourth year medical students which included training on the use of the defibrillator machine, how to handle cardiac or respiratory arrest and drugs used for resuscitation. A new CLS (cardiac life support) training session was introduced and increased to a oneday course where students were given practical training first, which included 5 stations (airway equipment, mega codes, drugs for resuscitation, defibrillator use and cardiac rhythm identification) , MCQ (multiple choice questions) test and a mega code (practical)assessment. Objective: To evaluate the students’ knowledge on cardiac resuscitation after a change in the delivery of the cardiac life support training (CLS). Methodology: Group I, consisted of 82 students taught using the traditional teaching and Group II consisted of 77 students taught using hands on simulation. The students in both groups had an online manual to read prior to the session, were given an identical written exam six months after the CLS training. Group II, however, had an online pre-test. Results: There was a statistical difference in the final mean marks between the two groups with group II scoring higher (67.3) than group 1 (62.1). No significant marks difference was noted between male and female students for both the cohorts. Conclusion: There is a significant difference in medical students’ knowledge when cardiac life support is taught using simulation. IMU has adopted the new teaching method with simulated training for the cardiac life support courses with plans to implement higher fidelity and technology to the existing simulated teaching in other areas of medicine.

The presence of cutaneous metastases in squamous cell carcinomas of the head and neck (SCCHN) is rare and associated with a dismal prognosis. It is vital to distinguish these lesions from direct invasion of the skin by SCCHN or primary cutaneous malignancies as the prognosis is vastly different and so is the management. In this case report, we present four cases of cutaneous metastases and also briefly review the literature pertaining to this phenomenon.

PURPOSE: In this study, we investigated the molecular mechanism involved in ethanol (EtOH)-mediated proliferation of breast cancer cells. METHODS: EtOH concentration was optimized by studying its effect on cell proliferation in MCF-7 and MDA MB-231 cells. We used flow cytometry and immunoblot analysis to evaluate the increased proliferation caused by the optimized concentrations of EtOH. The mechanism of EtOH-mediated proliferation was determined using reactive oxygen species (ROS) release assay, reverse transcription polymerase chain reaction, and immunoblot studies. Gene silencing followed by quantitative real-time polymerase chain reaction studies and inhibitor studies indicated the involvement of signal transducer and activator of transcription 3 (STAT3) in EtOH-mediated breast cancer proliferation. RESULTS: Exposure to EtOH caused an increase in cell proliferation and an accumulation of cells in S-phase in MCF-7 (347 µM EtOH) and MDA MB-231 (173 µM EtOH) cells. Additionally, increased release of ROS and the expression of pro-inflammatory cytokines, such as interleukin 6 and tumor necrosis factor α, confirmed that the proliferation was induced by the ROS-linked inflammatory response in breast cancer. The proinflammatory response was followed by phosphorylation of STAT3. The importance of STAT3 activation in EtOH-mediated proliferation was confirmed through the silencing of STAT3, followed by an investigation on the expression of cyclins and matrix metalloproteinases. Finally, studies using specific inhibitors indicated that the EtOH-mediated effect on STAT3 activation could be regulated by phosphoinositide-3-kinase and Janus kinase 2. CONCLUSION: The study demonstrates the involvement of STAT3 signaling in EtOH-mediated breast cancer proliferation.

Introduction: Gestational diabetes mellitus (GDM) increases risks for type 2 diabetes and cardiovascular diseases. Low glycaemic index (GI) diets improve cardio-metabolic outcomes in insulin-resistant individuals. We examined the feasibility of lowering GI through GI-based-education among Asian post-GDM women. Methods: A 3-month investigation was carried out on 60 Malaysian women with a mean age of 31.0±4.5 years and a history of GDM. Subjects were randomised into two groups: LGIE and CHDR. The CHDR group received conventional healthy dietary recommendations only. The LGIE group received GI based-education in addition to conventional healthy dietary recommendations. At baseline and after 3-months, dietary intake of energy and macronutrient intakes including GI diet and glycaemic load was assessed using 3-day food records. Diabetes-Diet and GI-concept scores and physical activity levels were assessed using a questionnaire. Adherence to dietary instructions was measured at the end of 3 months. Results: At the end of 3 months, the LGIE group had significant reductions in energy intake (241.7±522.4Kcal, P=0.037, ES=0.463), total carbohydrate (48.7±83.5g, P=0.010, ES=0.583), GI (3.9±7.1, P=0.017, ES=0.549) and GL (39.0±55.3, P=0.003, ES=0.705) and significant increases in protein (3.7±5.4g, 0.003, ES=0.685) and diet fibre (4.6±7.3g, P=0.06). The CHDR group had a significant reduction in fat only (5.7±9.4g, P=0.006, ES=0.606). There was a 30% increase in GI-concept scores in the LGIE group (p< 0.001). Changes in GI-concept scores correlated significantly to the reduction in dietary GI (r = -0.642, P=0.045). Dietary adherence was comparable in both groups. Conclusion: GI-education improves GI-concept knowledge and helps lower dietary glycaemic index among women with a history of GDM.

Abstract: Solitary adrenal metastasis is a rare presentation in breast cancer and it presents the clinician with a difficult therapeutic dilemma as there are no existing guidelines for optimal management. On literature review, we only found one published case report of solitary adrenal metastasis from infiltrating ductal carcinoma of the breast. Here we present a case of a 75 year-old lady who presented with a right breast lump which was subsequently confirmed to be infiltrating ductal carcinoma. She underwent a right mastectomy and axillary clearance. Computerised tomography (CT) staging revealed a solitary adrenal metastasis. She was treated with aromatase inhibitors and her tumour markers which were initially raised has now normalised.

Male breast cancer accounts for only 1% of cancers in men and 1% of breast cancers. Cutaneous metastases occur less than 10% of all patients with visceral malignancies and are considered a rare and late event in progression of metastatic disease. A 45-year-old man presented with a lump in the left breast which was confirmed to be infiltrating ductal carcinoma. He underwent a left mastectomy and axillary clearance followed by chemotherapy and radiotherapy to the left chest wall. However, he was non-compliant to adjuvant tamoxifen due to hot flushes. One year later, he presented with biopsy proven cutaneous metastases. Initially he had complete excision of the lesions, however, two months later more skin lesions appeared predominantly over the chest wall and back. Hormonal therapy failed to control the metastases as such he was treated with systemic chemotherapy. He is currently on third line chemotherapy.
