Acne vulgaris is an extremely common condition affecting the pilosebaceous unit of the skin and characterized by presence of comedones, papules, pustules, nodules, cysts, which might result in permanent scars. Acne vulgaris commonly involve adolescents and young age groups. Active acne vulgaris is usually associated with several complications like hyper or hypopigmentation, scar formation and skin disfigurement. Previous studies have targeted the efficiency and safety of local and systemic agents in the treatment of active acne vulgaris. Superficial chemical peeling is a skin-wounding procedure which might cause some potentially undesirable adverse events. This study was conducted to review the efficacy and safety of superficial chemical peeling in the treatment of active acne vulgaris. It is a structured review of an earlier seven articles meeting the inclusion and exclusion criteria. The clinical assessments were based on pretreatment and post-treatment comparisons and the role of superficial chemical peeling in reduction of papules, pustules and comedones in active acne vulgaris. This study showed that almost all patients tolerated well the chemical peeling procedures despite a mild discomfort, burning, irritation and erythema have been reported; also the incidence of major adverse events was very low and easily manageable. In conclusion, chemical peeling with glycolic acid is a well-tolerated and safe treatment modality in active acne vulgaris while salicylic acid peels is a more convenient for treatment of darker skin patients and it showed significant and earlier improvement than glycolic acid
The purpose of the study was to examine the consumption practices and perception of ready-to-eat food among university students and employees in Kuala Lumpur, Malaysia. Through random sampling, a total of ninety-three respondents participated by answering questionnaires. The results showed that majority of the respondents (52%) consumed RTE food two to four times a week, and most of them (44%) consumed RTE food during lunch. The biggest motivator for the respondents to purchase RTE food was convenience (46%). It could be highlighted that majority of the respondents felt that fast-food restaurants to be very safe (11.8%), and that street foods to be very risky (34.4%). Most of the respondents were very worried about human spread diseases (such as Hepatitis B) and human spread bacteria (such as E. coli) when buying food (43%). When buying RTE food, consumers were most concerned about the cleanliness of the store they were buying their food from (66.7%). The present study indicated that university students and employees showed food safety awareness and concerns especially regarding RTE food. This study could benefit food marketers, and also public health organizations in their efforts to develop more effective education and dissemination of information to the public.
Cholera is an acute secretory diarrheal disease that is perceived by World Health Organization (WHO) to be a highly contagious threat. Firstly discovered by an Italian physician, Filippo Pacini, the disease gains a reputation as the most feared epidemic diarrheal disease encountered in developing countries. Despite effort taken by WHO to reduce the incidence rate, cholera-endemic prevail in certain regions. Factors that contribute to the disease transmission and ongoing spreading in cholera-prone areas remain as elusive. Should an awareness and knowledge of cholera be developed, it is the residents of developing nation that stand to benefit the most. This review gives insight into the disease prevalence, pandemic, epidemiology, pathogenesis, disease transmission, major strategies and steps to be pursued toward controlling cholera.
Cholera is a major infectious disease, affecting millions of lives annually. In endemic areas, implementation of vaccination strategy against cholera is vital. As the use of safer live vaccine that can induce protective immunity against Vibrio cholerae O139 infection is a promising approach for immunization, we have designed VCUSM21P, an oral cholera vaccine candidate, which has ctxA that encodes A subunit of ctx and mutated rtxA/C, ace and zot mutations. VCUSM21P was found not to disassemble the actin of HEp2 cells. It colonized the mice intestine approximately 1 log lower than that of the Wild Type (WT) strain obtained from Hospital Universiti Sains Malaysia. In the ileal loop assay, unlike WT challenge, 1×106 and 1×108 colony forming unit (CFU) of VCUSM21P was not reactogenic in non-immunized rabbits. Whereas, the reactogenicity caused by the WT in rabbits immunized with 1×1010 CFU of VCUSM21P was found to be reduced as evidenced by absence of fluid in loops administered with 1×102–1×107 CFU of WT. Oral immunization using 1×1010 CFU of VCUSM21P induced both IgA and IgG against Cholera Toxin (CT) and O139 lipopolysaccharides (LPS). The serum vibriocidal antibody titer had a peak rise of 2560 fold on week 4. Following Removable Intestinal Tie Adult Rabbit Diarrhoea (RITARD) experiment, the non-immunized rabbits were found not to be protected against lethal challenge with 1×109 CFU WT, but 100% of immunized rabbits survived the challenge. In the past eleven years, V. cholerae O139 induced cholera has not been observed. However, attenuated VCUSM21P vaccine could be used for vaccination program against potentially fatal endemic or emerging cholera caused by V. cholerae O139.
This study was aimed to evaluate consumers’ consumption practices of ready-to-eat (RTE) foods, food safety knowledge, and the relationship to gender and education level. A total of 258 consumers in Klang Valley, Kuala Lumpur, Malaysia were given questionnaires through convenience sampling. The results showed that the biggest motivation for consumers in purchasing RTE foods was convenience (47.3%). 40.7% of respondents purchase RTE foods more than twice a week, and 36.8% of respondents consumed RTE food at restaurants and cafes. A total of 54.3% of the respondents purchased RTE foods for lunch, and 48.1% of respondents usually spend RM11-RM20 per person. About 81% of respondents knew that the common symptom of foodborne disease is diarrhea, and 42.2% of respondents knew about the correct temperature for refrigeration. Most of the respondents (66.7%) knew that room temperature encourages the multiplication of bacteria, and 36.4% of respondents knew that bacteria will grow quickly at body temperature. About 60.9% of respondents knew that raw and cooked food should be separated to prevent the transfer of bacteria, and 62% of the respondents knew that placing raw meat in the plastic bag before putting it into the grocery basket decreases the chance of foodborne illness. However, only 10.1% of the respondents knew that the best way to clean a cutting board after using it for raw meat is by washing with bleach and water. Female respondents and those with higher education level generally had better food safety knowledge. This study could benefit RTE food marketers in gaining better insights into consumers’ behavior patterns towards RTE food. This study could also contribute to knowing the baseline knowledge of consumers in food safety as it is essential for the development of effective health educational programmes.
