exudates and Vomiting

Recent studies suggested that olanzapine, together with dexamethasone and serotonin-3 receptor antagonist (5HT3RA), is effective in preventing chemotherapy-induced nausea and vomiting (CINV) following highly emetogenic chemotherapy (HEC). This regimen is particularly useful in Southeast Asia (SEA) countries where resources are limited. We aimed to evaluate the cost-effectiveness of incorporating olanzapine into standard antiemetic regimens for the prevention of CINV in patients receiving HEC among SEA countries.. Using a decision tree model, clinical and economic outcomes associated with olanzapine-containing regimen and standard antiemetic regimen (doublet antiemetic regimen: dexamethasone+first generation 5HT3RA) in most SEA countries except in Singapore (triplet antiemetic regimen: dexamethasone+first generation 5HT3RA + aprepitant) for CINV prevention following HEC were evaluated. This analysis was performed in Thailand, Malaysia, Indonesia, and Singapore, using societal perspective method with 5-day time horizon. Input parameters were derived from literature, network meta-analysis, government documents, and hospital databases. Outcomes were incremental cost-effectiveness ratio (ICER) in USD/quality-adjusted life year (QALY) gained. A series of sensitivity analyses including probabilistic sensitivity analysis were also performed.. Compared to doublet antiemetic regimen, addition of olanzapine resulted in incremental QALY of 0.0022-0.0026 with cost saving of USD 2.98, USD 27.71, and USD 52.20 in Thailand, Malaysia, and Indonesia, respectively. Compared to triplet antiemetic regimen, switching aprepitant to olanzapine yields additional 0.0005 QALY with cost saving of USD 60.91 in Singapore. The probability of being cost-effective at a cost-effectiveness threshold of 1 GDP/capita varies from 14.7 to 85.2% across countries.. The use of olanzapine as part of standard antiemetic regimen is cost-effective for the prevention of CINV in patients receiving HEC in multiple SEA countries.

Ensuring adherence to chemotherapy is important to prevent disease progression, prolong survival and sustain good quality of life. Capecitabine is a complex chemotherapeutic agent with many side effects that might affect patient adherence to treatment. This cross sectional study aimed to determine adherence to capecitabine and its contributing factors among cancer outpatients in Malaysia. One hundred and thirteen patients on single regime capecitabine were recruited from Hospital Sultan Ismail and Hospital Kuala Lumpur from October 2013 to March 2014. Adherence was determined based on adherence score using validated Medication Compliance Questionnaire. Patient socio-demographics, disease, and treatment characteristics were obtained from medical records. Satisfaction score was measured using the validated Patient Satisfaction with Healthcare questionnaire. The mean adherence score was 96.1% (standard deviation: 3.29%). The significant contributing factors of adherence to capecitabine were Malay ethnicity [β=1.3; 95% confidence interval (CI): 0.21, 2.43; p value=0.020], being female [β=1.8; 95%CI: 0.61, 2.99; p value=0.003]), satisfaction score [β=0.08; 95%CI: 0.06, 1.46; p value=0.035], presence of nausea or vomiting [β=2.3; 95%CI: 1.12, 3.48; p value <0.001] and other side effects [β=1.45; 95%CI: 0.24, 2.65; p value=0.019]. Adherence to capecitabine was generally high in our local population. Attention should be given to non-Malay males and patients having nausea, vomiting or other side effects. Sufficient information, proactive assessment and appropriate management of side effects would improve patient satisfaction and thus create motivation to adhere to treatment plans.

Breast cancer is the leading cause of cancer-related death among women in Malaysia. A diagnosis is very stressful for women, affecting all aspects of their being and quality of life. As such, there is little information on quality of life of women with breast cancer across the different ethnic groups in Malaysia. The purpose of this study was to examine the quality of life in Malay and Chinese women newly diagnosed with breast cancer in Kelantan.. A descriptive study involved 58 Malays and 15 Chinese women newly diagnosed with breast cancer prior to treatment. Quality of life was measured using the Malay version of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30) and its breast-specific module (QLQ-BR23). Socio-demographic and clinical data were also collected. All the data were analyzed using SPSS version 20.0.. Most of the women were married with at least a secondary education and were in late stages of breast cancer. The Malay women had lower incomes (p=0.046) and more children (p=0.001) when compared to the Chinese women. Generally, both the Malay and Chinese women had good functioning quality-of-life scores [mean score range: 60.3-84.8 (Malays); 65.0-91.1 (Chinese)] and global quality of life [mean score 60.3, SD 22.2 (Malays); mean score 65.0, SD 26.6 (Chinese)]. The Malay women experienced more symptoms such as nausea and vomiting (p=0.002), dyspnoea (p=0.004), constipation (p<0.001) and breast-specific symptoms (p=0.041) when compared to the Chinese.. Quality of life was satisfactory in both Malays and Chinese women newly diagnosed with breast cancer in Kelantan. However, Malay women had a lower quality of life due to high general as well as breast-specific symptoms. This study finding underlined the importance of measuring quality of life in the newly diagnosed breast cancer patient, as it will provide a broader picture on how a cancer diagnosis impacts multi-ethnic patients. Once health care professionals understand this, they might then be able to determine how to best support and improve the quality of life of these women during the difficult times of their disease and on-going cancer treatments.

There is accumulating evidence that human rhinovirus (HRV) causes acute lower respiratory tract infections (ALRTI). Recently, HRV-C was identified as a new species of HRV, but its spectrum of clinical disease is not well understood.. We investigated the molecular epidemiology, demographic and clinical characteristics of HRVs among hospitalized children with ALRIs.. One hundred and sixty-five nasopharangeal aspirates taken from children <5 years hospitalized with ALRTIs in Serdang Hospital, Malaysia, were subject to reverse transcriptase-PCR for HRV. Phylogenetic analysis on VP4/VP2 and 5'-NCR regions was used to further characterize HRV. Other respiratory viruses were also investigated using semi-nested multiplex RT-PCR assay. Clinical parameters were analyzed between HRV, RSV and IFV-A mono-infections and between HRV species.. HRV was detected in 54 (33%) patients for both single (36 samples) and multiple (18 samples) infections, 61.1% (22/36) represents HRV-A strains while the remaining 14 HRV-C. Strain P51 was the first reported representative of HRV98. The majority of the single HRV cases were in the second half of infancy; HRV-C occurred among older children compared with HRV-A. HRV children were admitted significantly earlier and less febrile than RSV and IFV-A infection. HRV-C infected children were more likely to have rhonchi and vomiting as compared to HRV-A. Pneumonia was the most common discharge diagnosis followed by bronchiolitis and post-viral wheeze in HRV patients.. Our study showed high prevalence of HRVs and detection of HRV-C among hospitalized children with ALRTIs in Malaysia. Analysis of clinical parameters suggested specific features associated with HRVs infections and specific HRV groups.

In a prospective cohort study of antiemetic therapy conducted in Malaysia, a total of 94 patients received low emetogenic chemotherapy (LEC) with or without granisetron injections as the primary prophylaxis for chemotherapy-induced nausea and vomiting (CINV). This study is a retrospective cost analysis of two antiemetic regimens from the payer perspective.. This cost evaluation refers to 2011, the year in which the observation was conducted. Direct costs incurred by hospitals including the drug acquisition, materials and time spent for clinical activities from prescribing to dispensing of home medications were evaluated (MYR 1=$0.32 USD). As reported to be significantly different between two regimens (96.1% vs 81.0%; p=0.017), the complete response rate of acute emesis which was defined as a patient successfully treated without any emesis episode within 24 hours after LEC was used as the main indicator for effectiveness.. Antiemetic drug acquisition cost per patient was 40.7 times higher for the granisetron-based regimen than for the standard regimen (MYR 64.3 vs 1.58). When both the costs for materials and clinical activities were included, the total cost per patient was 8.68 times higher for the granisetron-based regimen (MYR 73.5 vs 8.47). Considering the complete response rates, the mean cost per successfully treated patient in granisetron group was 7.31 times higher (MYR 76.5 vs 10.5). The incremental cost-effectiveness ratio (ICER) with granisetron-based regimen, relative to the standard regimen, was MYR 430.7. It was found to be most sensitive to the change of antiemetic effects of granisetron-based regimen.. While providing a better efficacy in acute emesis control, the low incidence of acute emesis and high ICER makes use of granisetron as primary prophylaxis in LEC controversial.

Nausea and vomiting are recognized as two separate and distinct conditions with a wide spectrum of etiologies either directly associated with cancer itself or its treatment. According to the new ranking of chemotherapy side effects, nausea is the number one or the most disturbing side effects while vomiting is the third and sometimes the fifth. The introduction of 5-HT3-recptor antagonists in the early of 1990s has revolutionized the treatment of nausea and vomiting, these agents remaining the mainstay of antiemetic therapy today. Ethnic variation (due to genetic polymorphisms) may lead to diversity in antiemetic treatment pharmacokinetic and pharmacodynamic properties, in terms of distribution, elimination, disposition and clinical effects. The aim of the present study was to clarify genetic polymorphism effects in the three main races in Malaysia i.e., Malay, Chinese and Indian, on the clinical antiemetic effects of granisetron.. In this longitudinal prospective observational study, 158 breast cancer patients treated with chemotherapy were monitored for nausea and vomiting in the first 24 hours after chemotherapy administration. The patients were then followed up again after 3 to 5 days of chemotherapy.. Genetic polymorphisms in the three races in Malaysia have significant effect on granisetron clinical antiemetic action because each is characterized by variant CYP3A4 enzymatic action.. According to the result, different type of 5-HT3 receptor antagonists, such as tropisetron and dolasetron which are predominantly metabolized by CYP2D6, should be used especially for Chinese breast cancer patients.

Acetaminophen poisoning is a common clinical problem, and early identification of patients with more severe poisoning is key to improving outcomes.. This study intends to document prevalence, clinical characteristics, and predictors of gastrointestinal (GI) manifestations and to assess the impact of these manifestations on outcome in patients with acetaminophen poisoning.. This is a retrospective cohort study of hospital admissions for acute acetaminophen poisoning conducted over a period of 5 years from 1 January 2004 to 31 December 2008. Parametric and non-parametric tests were used to test differences between groups depending on the normality of the data. Statistical Package for Social Sciences (SPSS) 15 was used for data analysis.. Two hundred and ninety-one patients were studied; their mean age was 23.01 +/- 7.4 years and 76.6% had GI manifestations. Multiple logistic regression showed that significant risk factors for GI manifestations were present among patients who reported acetaminophen dose ingested >or=10 g (p < 0.001), and latency time more than 8 hours (p = 0.030). GI manifestations at first admission predicted poorer outcomes in terms of estimated acetaminophen levels to be a possible toxic (p < 0.001), elevated bilirubin levels (p = 0.002), prolonged prothrombin time (PT; p = 0.002), elevated creatinine level (p = 0.028), declination of potassium level (p < 0.001), and prolonged hospital stay (p < 0.001).. GI manifestations were common among patients with acetaminophen poisoning. This study suggests that the presence of GI manifestations at first presentation appears to be an important risk marker of subsequent hepatotoxicity and nephrotoxicity.

Chemotherapy-induced nausea and vomiting (CINV) is one of the most important worries of cancer patients. Although not life-threatening, it has a great negative impact on quality of life (QOL).. The aim of this study was to determine the impact of CINV (i.e., acute and delayed) on breast cancer patients QOL and to discern opinions related with antiemetic guidelines used dependent on the three main races in Malaysia (Malay, Chinese, Indian).. In this longitudinal prospective observational study, 158 breast cancer patients treated with chemotherapy were interviewed and valid questionnaires (MANE and ONEM) were used to report the impact of CINV on their QOL within the first 24 hours and after 3 to 5 days of chemotherapy treatment.. The main result was that delayed CINV has an impact on QOL greater than acute CINV. The impact of nausea was reportedly higher than that of vomiting. Also differences in race i.e., genetic polymorphisms (pharmacogenomics) influenced the utility of antiemetic treatments and patients opinions.. Based on the results of our study a new guideline for antiemetic treatment should be used to reduce the impact of CINV on QOL, taking into account variation in genetic polymorphisms among the three races in Malaysia.

Analysis on fly artifacts produced by forensically important blowfly, Chrysomya megacephala (Fabricius) (Diptera:Calliphoridae), revealed several unique patterns. They can be divided into fecal spots, regurgitation spots and swiping stains. The characteristics of fecal spots are round with three distinct levels of pigmentation; creamy, brownish and darkly pigmented. Matrix of the spots appears cloudy. The round spots are symmetrical and non-symmetrical, delineated by irregular and darker perimeter which only visible in fairly colored fecal spots. Diameter of these artifacts ranged from 0.5 mm to 4 mm. Vomit or regurgitation spots are determined by the presence of craters due to sucking activity of blowflies and surrounded by thickly raised and darker colored perimeter. The size of these specks ranged from 1 mm to 2 mm. Matrix of the spots displays irregular surface and reflective under auxiliary microscope light. Swiping stains due to defecation by flies consists of two distinguishable segments, the body and tail. It can be seen as a tear drop-like, sperm-like, snake-like and irregular tadpole-like stain. The direction of body and tail is inconsistent and length ranged between 4.8 mm to 9.2 mm. A finding that should be highlighted in this observation is the presence of crater on tadpole-like swiping stain which is apparent by its raised border characteristic and reflective under auxiliary microscope light. The directionality of this darkly brown stain is random. This unique mix of regurgitation and swiping stain has never been reported before. Highlighting the features of artifacts produced by flies would hopefully add our understanding in differentiating them from blood spatters produced from victims at crime scenes.

To describe the clinical features, management and outcome of children with cyclic vomiting syndrome (CVS) from South-East Asia.. Retrospective review of all children who fulfilled the diagnostic criteria of CVS and who were seen at Department of Paediatrics, University of Malaya Medical Centre, Kuala Lumpur and Paediatric Unit, Penang Hospital, Penang, Malaysia from 1987 to 1997.. Eight children with CVS were seen at the two units during the study period, five girls and three boys. All had cyclical, self-limited episodes of nausea and vomiting with symptom-free intervals. The mean age of onset was 5.9 years. The clinical features were similar to other series described in the literature. Only two of the eight children were described as 'perfectionist'. Two children identified stress as precipitating factors. Therapy to reduce the number of emeses during acute attacks and to prevent subsequent attacks had been ineffective.. There are similarities and differences in CVS from South-East Asian children as compared to those described in the literature.

Stool samples from 836 cases with diarrhea and acute gastroenteritis from the Pediatric ward, Penang General Hospital, were examined for Cryptosporidium oocysts. A dimethyl sulfoxide modified acid fast technique was used for the identification of the parasites. 36 samples or 4.3% were found to be positive for Cryptosporidium. The prevalence of infection was higher (2.39%) in children with diarrhea and vomiting than in children with acute gastroenteritis alone (0.8%). Stool examination and cultures from the Cryptosporidium positive samples revealed no other parasites, rotavirus or enteropathogenic bacteria. This suggests that Cryptosporidium may be an important agent in the causation of diarrhea in young children. A routine laboratory examination for the detection of Cryptosporidium in the search for causal agents of childhood diarrhea in our environment may, therefore, be significant.

In the context of this study the ethnic origin of the patients revealed no noteworthy difference in the clinical reaction to the parasite; neither did age or sex of the patients. Any minor differences whcih appeared in length of history before seeking treatment and frequency of repeat attacks were more a reflection of the cultural pattern of response to illness (i.e. resort to traditional medicines) and the distance between the patient's home and the doctor rather than any altered response on the part of the host to the parasite. However, the fact that about 35 per cent of all the episodes had a history of eight or more days (about 10 per cent more than 30 days) suggest that more "malaria consciousness" is called for in what is after all an endemic malaria area. The value (and necessity) of repeated examination of the blood to detect the parasite is confirmed but it is also encouraging to note that in 84% of cases a single careful examination of the blood revealed the parasite. Since in 49% of our malaria episodes the patient was afebrile when the parasite was discovered, it is obvious that in outpatient practice especially blood should be examined when the patient presents for treatment, irrespective of the presence or absence of pyrexia. As always, a prerequisite to the diagnosis of malaria is an awareness of its possible presence.
