    The aim of this study was to determine the role of macrophages in the Actinobacillus actinomycetemcomitans-induced murine immune response. BALB/c mice were given carrageenan solution by intraperitoneal injection before immunisation with heat-killed A. actinomycetemcomitans. Mice immunised with antigens and phosphate-buffered saline served as positive and negative controls, respectively. One week after the last immunisation, the delayed-type hypersensitivity (DTH) response was assessed by measurement of footpad swelling. Serum IgG and IgM anti-A. actinomycetemcomitans antibody levels and culture supernate levels of interferon (IFN)-gamma were determined by ELISA. The diameter of abscess formation was determined every 5 days. Sham-immunised spleen cells were transferred to carrageenan-untreated recipients (groups A and B) and to carrageenan-treated recipients (group D). Antigen-immunised spleen cells were transferred to carrageenan-untreated (group C) and carrageenan-treated (group E) recipients. The carrageenan-treated recipients in groups F and G received macrophages from antigen- and sham-immunised mice respectively. All mice except those in group A were immunised with antigen 24 h after cell transfer. After 1 week, a partial suppression of DTH response, reduced levels of IFN-gamma, serum IgG and IgM anti-A. actinomycetemcomitans antibodies and delayed healing were seen in carrageenan-treated mice when compared with the positive control. The immune response to A. actinomycetemcomitans in groups A, B and D was lower than that in groups C and E. Healing of the lesion in the former groups was also delayed when compared with the latter groups. The immune response and the healing of the lesion could be partially restored in carrageenan-treated mice that received antigen-pulsed macrophages (group F) but not in those that received naive macrophages (group G). These results suggest that macrophages play a partial role in the induction of the murine immune response to A. actinomycetemcomitans.

    Anti-vascular endothelial growth factor (anti-VEGF) injections have revolutionized the field of ophthalmology, and their use in a variety of retinal diseases is growing. One target disease is peripheral exudative hemorrhagic chorioretinopathy, a disease that is uncommon and poorly understood. Despite this, there are numerous studies and case reports outlining the potential role of intravitreal injection of anti-VEGF medicines to treat it. As such, an evidence-based understanding of its risk-benefit profile is vital. We performed a comprehensive search in the PubMed, Google Scholar, and Cochrane databases for published studies and case reports relating to the use of anti-VEGF injections in peripheral exudative hemorrhagic chorioretinopathy. Anti-VEGF was first used in 2010 to aid in the management of peripheral exudative hemorrhagic chorioretinopathy. Since then, it has been increasingly used to manage this disease. Other potential management strategies, including laser photocoagulation, cryotherapy, photodynamic therapy, and vitrectomy are explored and compared with anti-VEGF where possible. Anti-VEGF appears to be an effective therapy in managing peripheral exudative hemorrhagic chorioretinopathy, especially when there is an exudative threat to the macula.

    BACKGROUND: Since the enforcement of the Movement Control Order (MCO) to contain the spread of COVID -19 infection in Malaysia, most clinic appointments have been rescheduled and procedures and surgeries postponed to a later date. Clinic appointments including intravitreal endothelial growth factor (anti-VEGF) treatment for patients with diabetic macular edema (DME) were also no exception to the postponement. This measure takes a psychological toll on patients because of the overwhelming concern for their eye condition. This study was conducted to assess the psychological status of DME patients with delayed anti-VEGF treatment during the pandemic.

    METHODS: A cross-sectional study was conducted from September 2020 to March 2021 in Ophthalmology Clinic Hospital Canselor Tuanku Muhriz Universiti Kebangsaan Malaysia (HCTM UKM). Subjects diagnosed with center-involved DME aged between 20 to 80 years who experienced delayed anti-VEGF injection were recruited. Level of depression, anxiety and stress were assessed using DASS-21 questionnaire. Statistical analysis using non-parametric tests were performed to determine the relationship between the DASS-21 score and duration of last injection, in those whose vision was affected by delayed injection and the relationship to the impact of COVID-19 pandemic. Statistical significance was denoted as p < 0.05.

    RESULTS: A total of 86 respondents with median age of 69 years old participated in this study. Most respondents were Malays (n = 47,54.7%) males (n = 51, 59.3%), had education up to secondary level (n = 37, 43%), unemployed (n = 78, 90.7%), married (n = 72, 83.7%) and living with their family (n = 82, 95.3%). The number of intravitreal injections received was at least three times among the respondents (n = 81, 94.2%). More than half of the respondents (n = 46, 53.5%) had been postponed for more than 12 weeks and felt that their vision was affected after delayed intravitreal injection (n = 47, 54.7%). Most of the subjects did not experience depression, anxiety, or stress. However, there was a significant level of stress scores among those with delayed injection of 9 to 12 weeks (p = 0.004), and significant anxiety (p = 0.029) and stress (p = 0.014) scores found in subjects with vision affected due to delayed treatment.

    CONCLUSION: The level of anxiety and stress can be significant in DME patients who experienced delay in intravitreal anti-VEGF treatment. Assessment of psychosocial impacts is important to identify early mental health issues potentially leading to the onset of psychiatry illness, thus early intervention is indispensable.

    BACKGROUND AND AIMS: Many patients who presented to Universiti Kebangsaan Malaysia Medical Centre (UKMMC) with signs and symptoms of urolithiasis had mild hydronephrosis with non visualization of calculus on ultrasound examination. These patients underwent an intravenous urogram (IVU) in order to determine the presence of urolithiasis and most of them had normal IVU. The main aim of this study was to determine the predictive value of urinalysis in this group of patients in determining the need for IVU examinations.
    MATERIALS AND METHODS: Retrospectively the ultrasound, urinalysis and intravenous urography reports of 53 patients were reviewed and evaluated.
    RESULTS: The positive predictive and negative predictive value of urinalysis was found to be 68% and 96.4%, respectively. CONCLUSIONS; The results indicate that the urinalysis was an excellent negative predictor for IVU. In view of high radiation dose, risk of contrast reaction and contrast induced nephropathy of IVU, we suggest that it should not be performed in patient with non visualization of calculus mild hydronephrosis when the urinalysis is negative for blood.

    In recent years, the use of bone marrow mesenchymal stem cell (BMSC) implantation has provided an alternative treatment for osteoarthritis. The objective of this study is to determine whether or not an intra-articular injection of a single dose of autologous chondrogenic induced BMSC could retard the progressive destruction of cartilage in a surgically induced osteoarthritis in sheep. Sheep BMSCs were isolated and divided into two groups. One group was cultured in chondrogenic media containing (Ham's F12:DMEM, 1:1) FD+1% FBS+5 ng/ml TGFβ3+50 ng/ml IGF-1 (CM), and the other group was cultured in the basal media, FD+10% FBS (BM). The procedure for surgically induced osteoarthritis was performed on the donor sheep 6 weeks prior to intra-articular injection into the knee joint of a single dose of BMSC from either group, suspended in 5 ml FD at density of 2 million cells/ml. The control groups were injected with basal media, without cells. Six weeks after injection, gross evidence of retardation of cartilage destruction was seen in the osteoarthritic knee joints treated with CM as well as BM. No significant ICRS (International Cartilage Repair Society) scoring was detected between the two groups with cells. However macroscopically, meniscus repair was observed in the knee joint treated with CM. Severe osteoarthritis and meniscal injury was observed in the control group. Interestingly, histologically the CM group demonstrated good cartilage histoarchitecture, thickness and quality, comparable to normal knee joint cartilage. As a conclusion, intra-articular injection of a single dose of BMSC either chondrogenically induced or not, could retard the progression of osteoarthritis (OA) in a sheep model, but the induced cells indicated better results especially in meniscus regeneration.

    BACKGROUND: Pain after laparoscopic cholecystectomy remains a major challenge. Ondansetron blocks sodium channels and may have local anesthetic properties.

    AIMS: To investigate the effect of intraperitoneal administration of ondansetron for postoperative pain management as an adjuvant to intravenous acetaminophen in patients undergoing laparoscopic cholecystectomy.

    METHODS: Patients scheduled for elective laparoscopic cholecystectomy were randomized into two groups (n = 25 each) to receive either intraperitoneal ondansetron or saline injected in the gall bladder bed at the end of the procedure. The primary outcome was the difference in pain from baseline to 24-h post-operative assessed by comparing the area under the curve of visual analog score between the two groups.

    RESULTS: The derived area under response curve of visual analog scores in the ondansetron group (735.8 ± 418.3) was 33.97% lower than (p = 0.005) that calculated for the control group (1114.4 ± 423.9). The need for rescue analgesia was significantly lower in the ondansetron (16%) versus in the control group (54.17%) (p = 0.005), indicating better pain control. The correlation between the time for unassisted mobilization and the area under response curve of visual analog scores signified the positive analgesic influence of ondansetron (rs =0.315, p = 0.028). The frequency of nausea and vomiting was significantly lower in patients who received ondansetron than that reported in the control group (p = 0.023 (8 h), and 0.016 (24 h) respectively).

    CONCLUSIONS: The added positive impact of ondansetron on postoperative pain control alongside its anti-emetic effect made it a unique novel option for patients undergoing laparoscopic cholecystectomy.

    This study reports the influence of peste des petits ruminants (PPR) vaccination on the clinico-pathological outcomes of PPR in the face of an outbreak. Twenty-two West African dwarf goats procured for a different study started showing early signs of PPR during acclimatization. In response, PPR vaccine was administered either intranasally with phytogenic mucoadhesive gum (Group A; n = 6) or without gum (Group B; n = 6); subcutaneously (Group C; n = 6) or not vaccinated (Group D; n = 4) and studied for 21 days. The clinical scores, hematology, serology and pathology scores were evaluated. Clinical signs of PPR were present in all groups, presenting a percentage mortality of 33%; 33%; 64% and 100% for Groups A, B, C, and D, respectively. Polycythemia and mild leukopenia were observed in all groups, and all animals were seropositive by day 7 post-vaccination. The lung consolidation scores were low in Groups A and B, compared to Group C. Histopathological lesions consistent with PPR was observed in the lymphoid organs, gastrointestinal tract, and lungs with the presence of PPR antigen as detected by immunohistochemistry. The findings suggest that intranasal vaccination with or without mucoadhesive gum may influence the outcome of PPR infection more than the subcutaneous route in the face of an outbreak.

    Endometriosis is a disease known to be detrimental to fertility. Women with endometriosis, and the presence of endometrioma, may require artificial reproductive techniques (ART) to achieve a pregnancy. The specific impact of endometrioma alone and the impact of surgical intervention for endometrioma on the reproductive outcome of women undergoing IVF/ICSI are areas that require further clarification. The objectives of this review were as follows: (i) to determine the impact of endometrioma on IVF/ICSI outcomes, (ii) to determine the impact of surgery for endometrioma on IVF/ICSI outcome and (iii) to determine the effect of different surgical techniques on IVF/ICSI outcomes.

    It is still uncertain as to which form of anaesthesia is the optimum. We conducted a study to identify the best location and optimum volume of anaesthetic agent in order to achieve best pain relief and cooperation from our patients. We also assessed the need for local anaesthetic gel for probe lubrication and if the number of cores during biopsy makes a difference in the pain score.

    INTRODUCTION: Chronic, nonspecific low back pain is a difficult ailment to treat and poses an economic burden in terms of medical expenses and productivity loss. The aim of this study was to determine the efficacy and safety of intramuscular metylcobalamin in the treatment of chronic nonspecific low back pain.
    METHODS: This was a double-blinded, randomised, controlled experimental study. 60 patients were assigned to either the methylcobalamin group or the placebo group. The former received intramuscular injections of 500 mcg parenteral methylcobalamin in 1 ml solution three times a week for two weeks, and the placebo group received 1 ml normal saline. Patients were assessed with Oswestry Disability Index questionnaire Version 2.0 and Visual Analogue Scale pain score. They were scored before commencement of the injections and at two months interval.
    RESULTS: Of the 60 patients, 27 received the placebo injections and 33 were given methylcobalamin injections. A total of 58 patients were available for review at two months (placebo: n is 26; methylcobalamin: n is 32). There was a significant improvement in the Oswestry Disability Index and Visual Analogue Scale pain scores in the methylcobalamin group as compared with the placebo group (p-value less than 0.05). Only minor adverse reactions such as pain and haematoma at the injection sites were reported by some patients.
    CONCLUSION: Intramuscular methylcobalamin is both an effective and safe method of treatment for patients with nonspecific low back pain, both singly or in combination with other forms of treatment.

    BACKGROUND: The role of endothelial injury and circulating adhesion molecule in the development and progression of diabetic peripheral neuropathy in the long-term has been established previously.
    AIMS: To study the effects of short-term glycemic control using insulin and oral hypoglycemic agent therapy (OHA) on the peroneal nerve function and vascular cell adhesion molecule-1 (VCAM-1) and advanced glycation endproducts (AGE) levels in type 2 diabetic patients.
    SETTINGS AND DESIGN: A randomized controlled study involving poorly controlled (HbA1c, 7.5%-11%) type 2 diabetic patients attending the endocrinology outpatient center in a tertiary hospital in Kuala Lumpur.
    MATERIALS AND METHODS: Twenty-nine patients were randomized to receive insulin (n=15) or OHA (n=14) for 8 weeks. The glycemic variables (HbA1c, fasting plasma glucose [FPG], fructosamine), VCAM-1, serum AGE and the peroneal motor conduction velocity (PMCV) were measured at baseline and at 4-week intervals.
    STATISTICAL ANALYSIS USED: Paired 't' test or Kruskal Wallis test; and the unpaired 't' test or Mann-Whitney U test were used for within-group and between-group analyses, respectively. Correlation was analyzed using Spearman's correlation coefficient.
    RESULTS: Within-group analysis showed significant progressive improvement in HbA1c at weeks 4 and 8 in the insulin group. The PMCV improved significantly in both groups by week 8, and by week 4 (P = 0.01) in the insulin group. PMCV correlated negatively with VCAM-1 (P = 0.031) and AGE (P = 0.009) at week 8.
    CONCLUSION: Aggressive glycemic control with insulin improves the peroneal nerve function within 4 weeks. Improvement in the serum VCAM-1 and AGE levels correlated significantly with improvement in peroneal nerve conduction velocity only in the insulin group.

    In this study, the effects of palm vitamin E (PV) supplementation on glycemic control and lipid profile in diabetic-induce Sprague-Dawley rats have been evaluated. Diabetes in the rats was induced by a single intravenous streptozotocin (50 mg/kg body weight). The diabetic rats were divided into two groups; supplemented with 200 mg/kg body weight/day of PV and non-supplemented with PV (No PV group). Non-diabetic rats (NDM) formed the control group and only received saline injection. After eight weeks of daily supplementation, PV significantly lowered the fasting blood glucose (FBG) and glycosylated haemoglobin (HbA1c) levels (p

    Introduction: The present study aims to investigate the effects of nicotine on foetal loss,
    postnatal growth and corresponding levels of oestrogen and progesterone in pregnant rats.
    Methods: Subcutaneous injection of nicotine tartrate (7.5 mg/kg/day) was administered to
    groups of pregnant rats; with treatment scheduled from day 1 through day 5, day 5 through
    day 9 or day 1 through day 9 of pregnancy. On day 10 of pregnancy, laparotomy was
    performed to count the number of blastocyst implantation sites. During parturition, the
    number of viable pups was recounted and statistically compared with the controls. One
    group of rats which received nicotine from day 1 through day 9 of pregnancy was sacrificed
    on day 16 of pregnancy, and circulating levels of oestrogen and progesterone were
    measured. Upon delivery, the birth weight of the pups was measured, and their weights were
    recorded until weaning. Results: There was a significant increase in foetal loss particularly in
    rats which received nicotine from day 5 through day 9 and from day 1 through day 9 of
    pregnancy. There was also significantly lower birth weight of pups in all groups; however,
    this pattern did not continue until weaning. Plasma oestrogen level was significantly elevated
    with a significant decrease in the plasma progesterone level. Conclusions: Nicotine
    administration during pregnancy showed an increase in foetal loss with a corresponding
    increase in oestrogen and decrease in progesterone levels. Although the birth weight of the
    pups was low, there was catch-up growth in the pups.

    This study investigated the dose-dependent and time-course effects of intramuscular (i.m.) and intraperitoneal (i.p.) injection of benzo[a]pyrene (BaP) on the biomarkers EROD activity, GST activity, concentrations of BaP metabolites in bile, and visceral fat deposits (Lipid Somatic Index, LSI) in African catfish (Clarias gariepinus). Intraperitoneal injection resulted in 4.5 times higher accumulation of total selected biliary FACs than i.m. injection. Hepatic GST activities were inhibited by BaP via both injection methods. Dose-response relationships between BaP injection and both biliary FAC concentrations and hepatic GST activities were linear in the i.p. injected group but nonlinear in the i.m. injected fish. Hepatic EROD activity and LSI were not significantly affected by BaP exposure by either injection route. We conclude that i.p. is a more effective route of exposure than i.m. for future ecotoxicological studies of PAH exposure in C. gariepinus.

    PURPOSE: To determine if adequate anesthesia and akinesia could be obtained using an inferonasal quadrant sub-Tenons anaesthesia for cataract surgery.
    METHODS: The sub-Tenons method of local anaesthesia was used in 50 patients undergoing extracapsular cataract extraction and lens implantation. The technique following was that described by JD Stevens in his study of 50 patients. Posterior sub-Tenons space was approached through a conjunctival incision in the inferonasal quadrant and the anaesthetic solution delivered by an irrigating cannula. The patients were assessed for residual ocular movements just before surgery. Effectiveness of anaesthesia was assessed during surgery using a verbal pain rating score. Scoring was based on the concept of a visual analogue pain score chart.
    RESULTS: Total akinesia was obtained in 20% patients and total anaesthesia in 24% patients. The remainder of the patients had adequate akinesia and anaesthesia to proceed with and complete the surgery.
    CONCLUSION: This method provides satisfactory anaesthesia for cataract surgery.
