    Pulsed light (PL) treatment is a non-thermal method for microbial decontamination on the
    surfaces of fresh-cut produce. The effect of pulsed light fluencies on microbiological stability
    and quality changes of fresh-cut yardlong beans were determined. Pulsed light treatments were
    carried out using an automatic laboratory flash lamp system (Steribeam XeMaticA-2L Kehl,
    Germany) at different fluencies (1.8 J/cm2, 5.4 J/cm2, 9.0 J/cm2 and 12.6 J/cm2). Microbiological
    quality (colour changes and textural changes) of fresh-cut yardlong beans stored at 4±1°C were
    monitored over 14 days. Results show that, the application of PL treatment at high fluencies
    allowed extension of microbiological shelf life up to 3-7 days in comparison to untreated
    samples. Apart from that, PL treated sample has no significant difference on the texture and
    colour as compared to untreated sample of fresh-cut yardlong bean. As a conclusion, the
    application of PL at dose 9.0 J/cm2 has increased the shelf life of fresh-cut yardlong bean while
    maintaining the quality when stored at 4±1°C.

    Pennywort (Centella asiatica) is a herbaceous vegetable commonly consumed raw as ‘ulam’ or salad. Consumption of raw leafy green vegetables is one of the pathogenic mechanisms that could cause foodborne outbreaks. The aim of the present work was therefore to investigate the effect of pulsed light (PL) treatment at fluences of 1.5, 4.2, 6.9, 9.6, and 12.3 J/cm² on the microbiological and physical quality of pennywort stored at 4 ± 1°C. Escherichia coli (E. coli) were inoculated onto the pennywort leaves before being exposed to PL and viewed using scanning electron microscopy (SEM). PL fluences of 6.9, 9.6, and 12.3 J/cm² significantly reduced the microbial count; however, the highest inactivation was obtained by using fluences of 9.6 and 12.3 J/cm². The color of pennywort was not significantly affected by PL treatment applied at lower fluences of 1.5, 4.2, and 6.9 J/cm²; however, at higher fluence, 9.6 and 12.3 J/cm², the color was affected. PL at 1.5, 4.2, 6.9, and 9.6 J/cm² was able to retain the texture appearance of the leaves. To conclude, PL at 6.9 J/cm² showed the best fluence to reduce total aerobic mesophilic count while retaining the physical properties of pennywort leaves and extend the shelf life to about four days. The inactivation of E. coli population was significantly higher at PL fluence of 6.9 J/cm². It was observed that PL caused the destruction to the surface of E. coli’s cell membrane. The reductions of samples inoculated with E. coli were better than those achieved in native microbiota. Furthermore, the present work also demonstrated that PL treatment was able to reduce the microbial count on pennywort leaves.

    The aim of the study was: to obtain the profile of patients (with regards to age and family history of breast cancer) with a palpable breast mass. To determine the validity of ultrasound in the assessment of the palpable breast mass by determining the sensitivity, specificity, positive predictive value, negative predictive value and accuracy of ultrasound in distinguishing a malignant mass. To determine the most discriminating ultrasound characteristics for differentiating benign and malignant masses. Seventy patients who had fine needle aspiration cytology of a palpable breast mass were subjected to an ultrasound assessment of the mass. The ultrasound findings were classified as benign, indeterminate or malignant. These findings were then compared with either the cytology or histology results in cases that eventually had surgical excision. The age of the patients ranged from 15 to 66 years old The majority was in the third and fourth decades with an average age of 25 years. The 8 patients with a proven malignant breast mass were aged between 39 and 66 years old. They did not have any family history of breast cancer. Only 4 patients had a family history of breast carcinoma and all proved to have a benign breast lesion. Ultrasound had a sensitivity of 100%, specificity of 85.7%, positive predictive value of 50%, negative predictive value of 100% and accuracy of 87.5% for distinguishing a malignant mass. For benign masses: 93.7% had well-defined margins, 81.3% had homogenous internal echoes, 91.7% had depth-width ratio of less than 1.0 and 89% were compressible. For malignant masses: 87.5% had either ill-defined or irregular margins, 87.5% had inhomogenous internal echoes and mixed posterior echoes, and 100% were incompressible. The majority of patients with a palpable breast mass were aged below 40 years old. Most of the patients with a malignant breast mass were aged 40 years and older. Neither a positive nor a negative family history of breast cancer had any significance on outcome. Ultrasound had high sensitivity, specificity and accuracy in distinguishing a malignant mass. The most discriminating benign ultrasound characteristic was compressibility. The most discriminating malignant ultrasound characteristic was ill-defined and irregular margins.

    Introduction : Selangor’s private clinic registry system had been introduced in 2006 following gazettment of The Private Healthcare Facilities and Services Act. Through the act, data’s from the private clinics can be obtained and its characteristics can be compared between the urban and rural private clinic. An overview of the services can be known and an appropriate action can be planned.
    Methodology : A cross-sectional study was done on private clinics registered in state of Selangor. Using databased known as MedPCs (Medical Practice Control System), a purposive sampling was used to select four districts – two urban and two rural. All private clinics in the selected districts were studied and all details shall be collected online.
    Result : District of Gombak and Klang were selected as urban and Sabak Bernam and Kuala Selangor represented rural area. Of a total 625 clinics selected, 90.0% (562) from urban and 10.0% (63) rural. Distributions of clinic were in line with the act. The most prominent services were general treatment (89.4%) and ability to serve more than eight hours daily (89.4%). Medical clinic still dominated at 84.0% compared to dentistry at 16.0%. About 70.6% were operated by male doctors. Though clinic services in rural were relatively as good as urban, the different were significantly observed to the ethnicity of the doctor. Indian doctors more in rural (46.03%), whilst in urban, Malay doctors were more dominant (39.50%). Followed closely by seniority, where rural doctors were much senior (51.02 years old), however, most of the doctors in rural private clinics experienced less exposure in government sectors, compared to those in urban areas.
    Conclusion : There were obvious difference in terms of distribution, where more clinics were located in urban compared to rural, but all were still in line to the act and their services were comparable. Most noticeable differences were ethnicity, seniority and past experience working in the public sector. Indian doctors were dominant in rural and Malay in urban. Although rural doctors were more senior, relatively they were less experienced working in the government sector.
