    A retrospective epidemiological study was done on 41 deaths among patients treated for TB in the Klang Chest Clinic for the year 1999. The findings revealed a male preponderance of TB deaths with Indians having the highest case fatality rate (8.6%). The majority of deaths occurred within the 25-44 year age group. Of those cases diagnosed as Pulmonary TB, 69% were diagnosed as far-advanced, at presentation, based on chest x-rays reported. Eighty three percent of these patients were still on treatment when they died. HIV was the most common co-existing disease condition and was implicated in 14.6% of the deaths. The recommendations include implementation of clinical guidelines on TB screening for HIV patients, a study to evaluate the effectiveness of the current TB surveillance programme and for chest x-rays of all sputum smear negative patients to be reported by the radiologist to reduce the risk of misdiagnosis.

    Determine HIV-1/2, Chembio HIV-1/2 STAT-PAK and PenTest are simple/rapid tests for the detection of antibodies to HIV-1 and HIV-2 in human whole blood, serum and plasma samples. The assay is one step and the result is read visually within 15 minutes. Using 92 known HIV-1 reactive sera and 108 known HIV-1 negative sera, the 3 HIV tests correctly identified all the known HIV-1 reactive and negative samples. The results indicated that Determine HIV-1/2, Chembio HIV-1/2 STAT-PAK and PenTest HIV are as sensitive and specific (100% concordance) as Microparticle Enzyme Immunoassay. The data indicated that these 3 HIV tests are effective testing systems for diagnosis of HIV infection in a situation when the conventional Enzyme Immunoassay is not suitable.

    The Medical Department of Sabah, in collaboration with various governmental and non-governmental agencies and 'Surgeons International' conducted a state-wide campaign for the 'Early Detection of Cancer' over a period of 3 months from July 1992. The purpose of the campaign was to educate the population about the early signs and symptoms of common cancers, to remove the myth that cancer was incurable and to impress on the public the need to detect cancer early for a possible cure and a better prognosis.

    A study was conducted to evaluate the cross flow tubular ultrafiltration behavior of aqueous solutions of pectin. The effectiveness of pulsatile flow as a cleaning-in-place (CIP) technique to improve permeate flux was undertaken on the above mentioned solution. This investigation is part of a study to apply membrane filtration in the clarification of tropical fruit juice. The main variables, which were investigated, include the concentration of pectin, pulse frequency and amplitude. It was found that the amount of pectin in the solution significantly affects its ultrafiltration behavior. From the observed profiles, it is evident that the formation of gel layer on the membrane surface is responsible for the leveling of flux at high pressures. The presence of pectin was found to affect the properties of the solution such as viscosity, pH and the size of pectin colloid. Improvements in the permeate flux for pectin solution were obtained by employing pulsatile flow cleaning-in-place technique. Both pulse frequency and amplitude are important parameters that can improve the improvement of in-situ cleaning method. Similar to several findings reported in the literature, pulsatile flow showed significant effectiveness of about 60% higher flux when the ultrafiltration process is operated under laminar condition.

    Three years ago the Universiti Kebangsaan Malaysia medical school changed its curriculum from the traditional discipline based curriculum to the integrated organ-system approach. Once change was effected a process of 'refreezing' had to be initiated whereby new responses had to be reintegrated into the ongoing personality or emotional relationships of important people so that the change process will endure and become stable. During this refreezing process the faculty encountered several problems which could thwart further development of the new curricula if left unresolved. The nature of the problems seemed to indicate that curricular change involves more than just efforts at bettering the what and ways of student learning and assessment. A lot of energy was also spent on keeping things going, keeping people motivated, making sure the work was done (at least as well as it has in the past), looking for better ways to do things, weighing new solutions and to be alert to new problems. In ensuring the continuance of change it was important to ensure, from the outset the institutionalization of policies, programmes, procedures and practices for continuing reward, routinization, structural integration into the system, continuing evaluation and providing for continuing maintenance.

    A turnaround time study was conducted for bacteriological culture tests in seven Malaysian general hospitals. The turnaround times were determined using a specially designed form that was completed by the ward staff. Doctors at these hospitals were also polled to find out whether they were satisfied with the promptness of bacteriological test reporting in their hospitals. The turnaround times obtained from this survey were found to be satisfactory taking into account the constraints of laboratory methods employed. Nevertheless only about a third of doctors expressed satisfaction with the timeliness of the bacteriological test reporting. Doctors and microbiologists should get together and agree on acceptable standards of turnaround times that are practical and reasonable.

    Over a seven month period in 1986, 164 (1.1%) of a total 15,131 neonates delivered in the Maternity Hospital, Kuala Lumpur were born to mothers with prolonged rupture of the fetal membranes. Septic work-ups were performed on 163 of these babies shortly after birth, 77 of them had no bacteriological, radiological or other clinical evidence of infection. The remaining 86 had additional history of illness. Nine of these 86 babies had proven infection: four with septicemia, one with meningitis and four others with congenital pneumonia. This study showed that neonates had risk of infection only when maternal history of prolonged rupture of the fetal membranes was associated with other clinical evidence of infection. However, even in this group of neonates at risk, 89.5% of them were not infected. Therefore, there is still a need to develop a simple, rapid, reliable and cheap laboratory method to help early identification of the infected from the non-infected neonates in order to prevent unnecessary antibiotic treatment and hospital stay.

    Genital discharge from patients unth. smear positive gonorrhoea was transported from the clinic to the laboratory in. Stuart's transport medium (Oxoid CM 111). Within. six hours of transit time the recovery rate of gonococci was 94%. When compared with "bedside" inoculation onto Modified Thayer Martin medium, there was no significant difference in recovery rates up to 6 hours of transportation in Stuart's transport medium, However, the rate of isolation of gonococci was significantly reduced after 20 to 30 hours of transportation. It is concluded that Stuart's transport medium is an acceptable transport medium for specimens containing gonococci when specimens reach the laboratory within 6 hours of collection.

    BACKGROUND/AIM: The effects of pericardium 6 (P6) electrical stimulation in patients at risk of postoperative nausea and vomiting (PONV) following laparoscopic surgery were evaluated.

    MATERIALS AND METHODS: Eighty patients for laparoscopic surgery with at least one of the determined risks (nonsmoker, female, previous PONV/motion sickness, or postoperative opioid use) were randomized into either an active or sham group. At the end of surgery, Reletex electrical acustimulation was placed at the P6 acupoint. The active group had grade 3 strength and the sham group had inactivated electrodes covered by silicone. It was worn for 24 h following surgery. PONV scores were recorded.

    RESULTS: The active group had significantly shorter durations of surgery and lower PONV incidence over 24 h (35.1% versus 64.9%, P = 0.024) and this was attributed to the lower incidence of nausea (31.4% versus 68.6%, P = 0.006). The overall incidence of vomiting was not significantly different between the groups, but it was higher in the sham group of patients with PONV risk score 3 (23.9%, P = 0.049).

    CONCLUSION: In patients at high risk for PONV, P6 acupoint electrical stimulation lowers the PONV incidence by reducing the nausea component. However, this reduction in nausea is not related to increasing PONV risk scores.

    Thermal performance curves (TPCs), which quantify how an ectotherm's body temperature (Tb ) affects its performance or fitness, are often used in an attempt to predict organismal responses to climate change. Here, we examine the key - but often biologically unreasonable - assumptions underlying this approach; for example, that physiology and thermal regimes are invariant over ontogeny, space and time, and also that TPCs are independent of previously experienced Tb. We show how a critical consideration of these assumptions can lead to biologically useful hypotheses and experimental designs. For example, rather than assuming that TPCs are fixed during ontogeny, one can measure TPCs for each major life stage and incorporate these into stage-specific ecological models to reveal the life stage most likely to be vulnerable to climate change. Our overall goal is to explicitly examine the assumptions underlying the integration of TPCs with Tb , to develop a framework within which empiricists can place their work within these limitations, and to facilitate the application of thermal physiology to understanding the biological implications of climate change.

    Samples of threadfin breams Nemipterus japonicus were collected from a village in Kuala Nyalau and a fish landing centre at Bintulu from April 2013 to March 2014. A total of 360 individuals of N. japonicus (214 male and 146 female) were used in this reproductive study.? The total length (TL) of individuals were measured to the nearest 0.1 cm and body weight (BW) was recorded to the nearest 0.1 g. Month-wise distribution of the sexes was significantly higher for males in September and March, while in the month of May the number of females was significantly higher (X(2) = 6.53; P < 0.05). Males showed a preponderance in the size-class of 19.0-20.9 cm (X(2) = 80.24; P < 0.001), 21.0 -22.9 cm (X(2) = 56.39; P < 0.001) and 23.0 -24.9 cm (X(2) = 17; P < 0.001). The gonadosomatic index (GSI) values of N. japonicus ranged from 0.07 to 0.19 for males and 0.34 to 4.99 for females. Females had higher GSI than males throughout the study period. For males, a higher GSI (0.11-0.19) was observed during January to February, while it was found to be higher (2.73-4.99) for females during January to March, indicating the spawning season. The present study revealed that ovarian maturity based on histological analysis of N. japonicus was classified into seven stages namely, immature (I), immature (II), maturing (III), mature (IV), ripe (V), spawning (VI) and spent (VII). The fecundity of N. japonicus was estimated to be within a range of 19221 to 85923 with higher GSI (3.08-6.78) from the coastal waters of Bintulu, Sarawak.
