    INTRODUCTION: The aim of this study was to investigate the efficacy of resveratrol and octreotide, agents that are used to prevent intra-abdominal adhesions in experimental models, in preventing intraperitoneal adhesions when used alone or in combination.

    MATERIALS AND METHODS: The study employed 28 young female Wistar albino rats weighing 250-300 grams. An experimental adhesion model was created in each rat using serosal abrasion and peritoneal excision. They were divided into four groups, each comprising seven rats: Group 1, adhesion induction only; Group 2, resveratrol administration only; Group 3, octreotide administration only; and Group 4, administration of resveratrol and octreotide combination. The rats were monitored under appropriate conditions for 14 days and then underwent laparotomy. Macroscopic intensity and extensiveness of adhesions and microscopic changes in the granulation tissue (cellular intensity, reticular and collagen fibers, capillaries, elastic and smooth muscle fibers, fibrosis) were evaluated and graded. Kruskal-Wallis and Mann-Whitney U-test were used in statistical analysis and the level of statistical significance was established as p <0.05.

    RESULTS: There was no significant difference between the groups in terms of the intensity and extensiveness of macroscopic adhesions (p=0.377 and p=0.319). There was a statistically significant difference between the microscopic scores of the groups according to Zühlke's classification (p=0.026). The Bonferroni correction used to test for the differences revealed that the rats in Group 1 achieved significantly higher scores than the rats in Group 3 (p=0.016).

    CONCLUSION: Octreotide showed higher efficiency compared to the control group in microscopic classification; however, the two agents were not superior to each other or their combination was not superior in preventing intra-abdominal adhesions.

    Primary bone lymphoma (PBL) is an uncommon type of extranodal lymphoma involvement. An anaplastic large-cell lymphoma (ALCL) is an extremely rare type of PBL, and it remains unclear whether ALCLs that primarily involve the bone exhibit favourable or unfavourable biological behaviour, and whether they are similar to ALCLs in general, or not. We reported a case of ALK-positive ALCL with primary bone involvement, and reviewed the clinicopathological features of 22 previously reported cases. An ALCL with primary bone involvement mostly affects younger patients with a preponderant towards the involvement of axial-bone. The prognosis of an ALCL that primarily involves bone is unfavourable, compared with PBL generally. The ALK-positive ALCLs in PBLs had less decedents than the ALK-negative ALCLs with a statistical non-significance (p=0.198).

    INTRODUCTION: Leptospirosis is a zoonotic disease caused by spirochaete of the genus Leptospira. Human infection occurs after exposure to water or soil contaminated by urine from an infected animal. Most patients manifest as self-limited systemic illness. However 10% of patients manifest as severe disease associated with high fatality. The disease affects mostly men, cases involving pregnant women are uncommon. We presented a case of leptospirosis in a pregnant woman leading to mortality of both mother and foetus.

    CASE REPORT: A 28-year-old woman at 18 weeks of gestation, had shortness of breath and collapsed. She was brought unconscious to the emergency department and died shortly after arrival. A week prior to this, she had presented to the same hospital with pain on both thighs. Examination of the patient and ultrasound of the foetus revealed normal findings. Post mortem examination revealed hepatosplenomegaly and congested lungs; no jaundice, meningeal inflammation or cardiac abnormalities was evident. Histopathology examination of the lungs revealed pulmonary haemorrhages and oedema. Multiple infarcts were seen in the spleen and the kidneys showed foci of acute tubular necrosis. Laboratory investigations revealed Leptospira IgM antibody and PCR for leptospira were positive. This case illustrates the subtleness of clinical presentation of leptospirosis. The diagnosis was obscure even at post-mortem and was only suspected following histopathological examination, leading to further investigations.

    CONCLUSION: Leptospirosis may have a subtle presentation and a high index of suspicion for this infection is required for early identification of the disease.

    INTRODUCTION: Intracranial teratomas account for 0.5% of all intracranial tumours and 2-4% of intracranial tumours in children. However, in terms of tumours of the pineal area, the exact incidence is not ascertained. Although, it is noted that 50-60% of central nervous system (CNS) germ cell tumours are found in the pineal gland. The degree of difficulty in the sampling of lesions in the pineal gland during biopsy emphasizes the importance of correlating the imaging studies, histopathologic findings, and serum and cerebrospinal fluid (CSF) tumour markers.

    CASE REPORT: This case report is that of a 9-year-old male who presented with frontal headache of eight days, with associated photophobia, nausea and vomiting, and diplopia. Biopsy with intraoperative navigation was done and the specimen was referred for histopathologic evaluation. The biopsy showed findings consistent with a mature teratoma with no histologic findings of an immature component or secondary somatic malignancy. Comparison of the pre-operative and post-operative multiaxial cranial CT scan showed findings that was consistent with a residual lesion. This was correlated with the pre-operative serum tumour markers which showed alpha-fetoprotein of 22.5 ng/mL and beta-HCG of 1.0 mIU/mL(IU/L), and the post-operative tumour markers of the cerebrospinal fluid that showed alpha-fetoprotein of 3.28 ng/mL and beta-HCG of 18.9 mIU/mL (IU/L).

    CONCLUSION: A review of the literature and comparison with current case in relation to the histopathologic, serum and CSF findings, and imaging studies was done to better understand the mechanism of this lesion.

    Sudden unexpected death in epilepsy (SUDEP) is a rare in children; the risk of SUDEP in children is up to 10-fold less than adults. Herein, we report a case of SUDEP in a 14-year-old boy. The post-mortem findings in neuropathological examination in SUDEP are not pathognomonic. Tongue and lip bites marks are only an indication of a seizure before death. Basically, there are no lesions that could explain the incidence of seizures before death. However, post-mortem examination is mandatory in order to determine the diagnosis of SUDEP. Autopsy, histopathological, and toxicologic examinations and a proper medical history of epilepsy are required to come to diagnosis of SUDEP. This case report further demonstrates the importance of medicolegal autopsy in allegedly dead victims.

    INTRODUCTION: Essential thrombocythaemia (ET) is a chronic myeloproliferative neoplasm (MPN) characterised by persistent thombocytosis. It is an indolent disorder but transformation to myelofibrosis (MF), acute myeloid leukaemia (AML) or myelodyplastic syndrome (MDS) has been reported.

    CASE REPORT: We described a patient with ET whose disease evolved into MDS with fibrosis and complex karyotype after 15 years of stable disease. She was asymptomatic and was on hydroxyurea (HU) treatment until recently when she presented with worsening anaemia. Physical examination showed mild splenomegaly. Full blood picture showed leukoerythroblastic picture with presence of 3% circulating blasts and background of dysplastic features such as hypogranular cytoplasm and nuclear hyposegmentation of neutrophils. The bone marrow aspiration was haemodiluted but revealed presence of 6% blast cells, trilineage dysplasia and predominant erythroid precursors (60%). Trephine biopsy showed no excess of blast cells and normal quantity of erythroid precursors, but there was increased in fibrosis (WHO grade 2) and presence of dysmegakaryopoeisis such as nuclear hypolobation, multinucleation and micromegakaryocytes. Cytogenetic study showed complex karyotype; monosomy of chromosome 2, chromosome 5, chromosome 18 and presence of a marker chromosome (42~44, XX,-2,-5,-18,+mar). Fluorescence in situ hybridisation (FISH) showed 5q deletion (CSF1R and EGR1).

    CONCLUSION: The findings were consistent with transformation of ET to MDS with fibrosis and complex karyotype. ET progression to MDS is considered rare. The presence of complex karyotype and fibrosis in MDS are associated with unfavourable outcome.

    A 43-year-old man presented with two-month history of fatigue, weakness, paleness, rectal bleeding, sweating, and weight loss of 10 kg in the past one month. A complete blood count revealed anaemia. The patient underwent a right hemicolectomy. The microscopic examination revealed an adenosquamous carcinoma associated with a mucinous adenocarcinoma in a patient with microsatellite instability due to loss of MLH1 and PMS2 expression and retention of MSH2 and MSH6 expression in both the squamous and glandular components. We also observed an atypical immunohistochemical phenotype in the adenocarcinoma component showing CK7 expression and reduced CK20 and CDX2 expression.

    INTRODUCTION: Primary uterine angiosarcoma is a very rare tumour, with only 23 cases described till now. It is a malignant tumour with cells variably recapitulating the morphologic features of an endothelium and expressing immunohistochemical markers of endothelial cells. In general, it is a bulky neoplasm and frequently is at advance stage of disease at presentation. In general, patients with uterine angiosarcoma tend to have a poorer prognosis, mostly related to the aggressive nature and the metastatic potential of these tumours.

    CASE REPORT: We report a rare case of primary uterine angiosarcoma with unusual rhabdoid morphology in a 41-year-old female, who underwent radical hysterectomy and died of disease after 4 months of treatment.

    DISCUSSION: We described the differential diagnosis of primary angiosarcoma of the uterus that can pose a diagnostic challenge.

    Fibrosis is known to be the hallmarks of chronic inflammation of the bowel. Epithelial damage due to inflammation compromises the barrier function of the gastrointestinal tract. This barrier dysfunction leads to further spread of inflammation resulting in a chronic state of inflammation. This chronic inflammation leads to development of fibrosis, which has very limited therapeutic options and usually requires surgical removal of the affected tissue. Our previous work has shown that Caffeic acid phenethyl ester (CAPE) is a naturally occurring anti-inflammatory agent, found in propolis, has been found to be protective in experimental colitis via enhancement of epithelial barrier function. However, the impact of CAPE on resolution of fibrosis in the long-term is unknown. The aim of this follow up study was to investigate the effect of CAPE on colon fibrosis in a chronic model of Dextran sulphate sodium induced colitis in mice. Dextran sulphate sodium (DSS) 2.5% w/v was administered in drinking water to induce colitis in C57/BL6 mice for 5 days on the 6th day DSS was stopped and test group mice were treated with intraperitoneal administration of CAPE (30 mg kg-1 day-1) for a further 7 days. Disease activity index (DAI) score, colon length and tissue histology and level of tissue fibrosis was observed. CAPE-treated mice had significantly lower levels of DAI, tissue inflammation scores and fibrosis as compared with control group. Our results show that CAPE is effective in resolving colon fibrosis in chronic inflammation. Thus, we can conclude CAPE could be a potential therapeutic agent for further clinical investigations for treatment of fibrosis in inflammatory bowel diseases in humans.

    BACKGROUND: Data are scarce on the availability and affordability of essential medicines for diabetes. Our aim was to examine the availability and affordability of metformin, sulfonylureas, and insulin across multiple regions of the world and explore the effect of these on medicine use.

    METHODS: In the Prospective Urban Rural Epidemiology (PURE) study, participants aged 35-70 years (n=156 625) were recruited from 110 803 households, in 604 communities and 22 countries; availability (presence of any dose of medication in the pharmacy on the day of audit) and medicine cost data were collected from pharmacies with the Environmental Profile of a Community's Health audit tool. Our primary analysis was to describe the availability and affordability of metformin and insulin and also commonly used and prescribed combinations of two medicines for diabetes management (two oral drugs, metformin plus a sulphonylurea [either glibenclamide (also known as glyburide) or gliclazide] and one oral drug plus insulin [metformin plus insulin]). Medicines were defined as affordable if the cost of medicines was less than 20% of capacity-to-pay (the household income minus food expenditure). Our analyses included data collected in pharmacies and data from representative samples of households. Data on availability were ascertained during the pharmacy audit, as were data on cost of medications. These cost data were used to estimate the cost of a month's supply of essential medicines for diabetes. We estimated affordability of medicines using income data from household surveys.

    FINDINGS: Metformin was available in 113 (100%) of 113 pharmacies from high-income countries, 112 (88·2%) of 127 pharmacies in upper-middle-income countries, 179 (86·1%) of 208 pharmacies in lower-middle-income countries, 44 (64·7%) of 68 pharmacies in low-income countries (excluding India), and 88 (100%) of 88 pharmacies in India. Insulin was available in 106 (93·8%) pharmacies in high-income countries, 51 (40·2%) pharmacies in upper-middle-income countries, 61 (29·3%) pharmacies in lower-middle-income countries, seven (10·3%) pharmacies in lower-income countries, and 67 (76·1%) of 88 pharmacies in India. We estimated 0·7% of households in high-income countries and 26·9% of households in low-income countries could not afford metformin and 2·8% of households in high-income countries and 63·0% of households in low-income countries could not afford insulin. Among the 13 569 (8·6% of PURE participants) that reported a diagnosis of diabetes, 1222 (74·0%) participants reported diabetes medicine use in high-income countries compared with 143 (29·6%) participants in low-income countries. In multilevel models, availability and affordability were significantly associated with use of diabetes medicines.

    INTERPRETATION: Availability and affordability of essential diabetes medicines are poor in low-income and middle-income countries. Awareness of these global differences might importantly drive change in access for patients with diabetes.

    In the recent past, Internet of Things (IoT) plays a significant role in different applications such as health care, industrial sector, defense and research etc.… It provides effective framework in maintaining the security, privacy and reliability of the information in internet environment. Among various applications as mentioned health care place a major role, because security, privacy and reliability of the medical information is maintained in an effective way. Even though, IoT provides the effective protocols for maintaining the information, several intermediate attacks and intruders trying to access the health information which in turn reduce the privacy, security and reliability of the entire health care system in internet environment. As a result and to solve the issues, in this research Learning based Deep-Q-Networks has been introduced for reducing the malware attacks while managing the health information. This method examines the medical information in different layers according to the Q-learning concept which helps to minimize the intermediate attacks with less complexity. The efficiency of the system has been evaluated with the help of experimental results and discussions.

    Perivascular adipose tissue (PVAT) refers to the local aggregate of adipose tissue surrounding the vascular tree, exhibiting phenotypes from white to brown and beige adipocytes. Although PVAT has long been regarded as simply a structural unit providing mechanical support to vasculature, it is now gaining reputation as an integral endocrine/paracrine component, in addition to the well-established modulator endothelium, in regulating vascular tone. Since the discovery of anti-contractile effect of PVAT in 1991, the use of multiple rodent models of reduced amounts of PVAT has revealed its regulatory role in vascular remodeling and cardiovascular implications, including atherosclerosis. PVAT does not only release PVAT-derived relaxing factors (PVRFs) to activate multiple subsets of endothelial and vascular smooth muscle potassium channels and anti-inflammatory signals in the vasculature, but it does also provide an interface for neuron-adipocyte interactions in the vascular wall to regulate arterial vascular tone. In this review, we outline our current understanding towards PVAT and attempt to provide hints about future studies that can sharpen the therapeutic potential of PVAT against cardiovascular diseases and their complications.

    Trans-resveratrol was earlier shown to lower intraocular pressure (IOP) in rats; however, its mechanisms of action remain unclear. It has been shown to modulate adenosine receptor (AR) and TGF-β2 signaling, both of which play a role in regulating IOP. Hence, we investigated effects of trans-resveratrol on AR and TGF-β2 signaling. Steroid-induced ocular hypertensive (SIOH) rats were pretreated with A1AR, phospholipase C (PLC) and ERK1/2 inhibitors and were subsequently treated with single drop of trans-resveratrol. Metalloproteinases (MMP)-2 and -9 were measured in aqueous humor (AH). In another set of experiments, effect of trans-resveratrol on AH level of tissue plasminogen activator (tPA) and urokinase plasminogen activator (uPA) was determined after single and multiple drop administration in SIOH rats. Effect of trans-resveratrol on ARs expression, PLC and pERK1/2 activation and MMPs, tPA and uPA secretion was determined using human trabecular meshwork cells (HTMC). Further, effect of trans-resveratrol on TGF-β2 receptors, SMAD signaling molecules and uPA and tPA expression by HTMC was determined in the presence and absence of TGF-β2. Pretreatment with A1AR, PLC and ERK1/2 inhibitors antagonized the IOP lowering effect of trans-resveratrol and caused significant reduction in the AH level of MMP-2 in SIOH rats. Trans-resveratrol increased A1AR and A2AAR expression, cellular PLC, pERK1/2 levels and MMP-2, tPA and uPA secretion by HTMC. Additionally, it produced TGFβRI downregulation and SMAD 7 upregulation. In conclusion, IOP lowering effect of trans-resveratrol involves upregulation of A1AR expression, PLC and ERK1/2 activation and increased MMP-2 secretion. It downregulates TGFβRI and upregulates SMAD7 hence, inhibits TGF-β2 signaling.

    Fibrous silica-titania (FST) catalysts were synthesized by microemulsion followed by silica seed-crystal crystallization methods under various molar ratios of toluene to water (T/W). The catalysts were characterized by XRD, UV-DRS, FESEM, TEM, AFM, N2 adsorption-desorption, FTIR, and ESR. The results revealed that altering the T/W ratio affected the growth of the silica and titania and led to different size, fiber density, silica-titania structure, and number of hydroxyl groups, as well as oxygen vacancies in the FSTs, which altered their behavior toward subsequent application. Photodegradation of ibuprofen (IBP) are in the following order: FST(6:1) (90%) > FST(5:1) (84%) > FST(7:1) (79%) > commercial TiO2 (67%). A kinetics study using Langmuir-Hinshelwood model illustrated that the photodegradation followed the pseudo-first-order and adsorption was the rate-limiting step. Optimization by response surface methodology (RSM) showed that the pH, initial concentration, and catalyst dosage were the remarkable parameters in photodegradation of IBP. The FST (6:1) maintained its photocatalytic activities for up to five cycles reaction without serious catalyst deactivation, and was also able to degrade other endocrine-disrupting chemicals, indicating its potential use for the treatment of those chemicals in wastewater.

    In order to address the issues of climate change through wise management of resources and environmental conservation, this study examined the intention and behavior towards green consumption among low-income households. This study was a cross-sectional that relied on 380 low-income household respondents who lived in coastal areas of Peninsular Malaysia. The findings revealed a positive effect of eco-literacy and self-efficacy on attitude towards green products. Subsequently, the findings also ascertained a positive effect of attitude and perceived behavioral control on intention and consumption of green products. In addition, both scholars and policymakers can rely on these findings to increase the intention and behavior towards the consumption of green products in order to reduce the environmental vulnerability to the coastal communities. Therefore, responsible organizations should implement programs and policies that minimize the adverse effects of climate change through resource management and environmental conservation by promoting the use of green products among Malaysians.

    We performed a retrospective observational analytical study looking at the frequencies and characteristics of multiple sclerosis(MS) and neuromyelitis optica spectrum disorders(NMOSD) in consecutive patients with idiopathic inflammatory demyelinating disease (IIDDs) attending three centers (2009-2017). Of 523 patients with IIDDs, there were 173 patients with NMOSD and 230 patients with MS. The percentage of NMOSD: IIDDs was 33%. The percentage of NMOSD:Total MS and NMOSD cohort was 43%. Of 141 seropositive NMOSD patients, 134(95%) were from the three main ethnic groups. The percentage of seropositive NMOSD to IIDDs and to combined MS and NMOSD was 26.9% and 35% respectively. Ratios of MS to NMOSD were nearly equal at 1.3 to 1.0, reinforcing the high ratio of NMOSD to MS in Asia. Nearly half of the Chinese cohort were seropositive ie; 71/141 (50%) with the remainder being Malays; 56/141 (39.7%) and Indians; 7/141 (5%). Amongst the other indigenous groups seropositivity was seen in 2 each of Iban, Bajau, Kadazan descent as well as one of Bidayuh origin. Comparatively, seropositivity in NMOSD is commoner amongst the Chinese compared to the Malays (p ≤ 0.005) and Indians, p ≤ 0.05 with ratios as high as 10:1. In the MS group of 230 subjects, 123(53.5%) were Malays (ratio of MS:NMOSD of 2:1), 41(17.8%) were Chinese, (ratio of MS:NMOSD of 0.5:1.0) and 54 (23.5%)were Indians (ratios of MS:NMOSD of 5:1 amongst the Indians). The remainder from East Malaysia were made up of 2 each of Kadazans, Ibans and Bajaus including 3 each of Bidayuh and Eurasian descent. Comparatively, in the NMOSD and MS cohorts a female preponderance was noted more so amongst Chinese NMOSD patients, with rare familial occurrence in both but more in Malay MS/NMOSD patients. This study also highlighted some of the inter-ethnic differences in presentation of MS and NMOSD amongst the 3 main ethnic races in Malaysia and confirms indigenous races having MS/NMOSD which needs further research. It also reviewed current literature on similar inter-ethnic differences world wide. To conclude, MS and NMOSD are the commonest demyelinating diseases seen in Malaysia with interesting inter-ethnic differences and similarities.

    We report a 72-year-old patient who presented with an ulcerated palatal mass, weight loss and adrenal insufficiency. Repeated biopsies from the mass revealed actinomycosis with no features of malignancy, while computed tomography scanning revealed a left maxillary sinus mass with invasive features and bilateral large adrenal masses. Blood and urine investigations showed adrenal insufficiency. The patient was treated as actinomycosis with adrenal involvement and was given intravenous penicillin and intravenous hydrocortisone. However, his condition did not improve and new signs appeared, that of left facial swelling and lymphadenopathy. A repeat biopsy of the palatal and adrenal masses revealed B-cell lymphoma. This case highlights the possibility that actinomycosis and lymphoma may share similar clinical presentations and may coexist. Either may mask and/or mimic the other, thus causing a delay in diagnosis. We describe the clinical progress and review the related literature. Interestingly, 9 out of the 12 reported cases of concomitant actinomycosis and malignancy (including this case) involve haematological malignancy. A high index of suspicion and treatment response reassessment is important in the management of either rare clinical entity.

    BACKGROUND: Malnutrition in older persons is a public health concern. This study aimed to estimate the prevalence of malnutrition and its associated factors among community-dwelling older persons in Sri Lanka.

    METHODS: A cross-sectional study was conducted in the Kandy district, Sri Lanka. The nutritional status of older persons was assessed using the Mini Nutritional Assessment -Short Form (MNA-SF). A standardised questionnaire was used to record factors associated with malnutrition: demographic characteristics, financial characteristics, food and appetite, lifestyle, psychological characteristics, physical characteristics, disease and care, oral health, and social factors. Complex sample multinomial logistic regression analysis was performed.

    RESULTS: Among the 999 participants included in the study, 748 (69.3%) were females and 251 (25.1%) were males. The mean age was 70.80 years (95% CI: 70.13, 71.47). The prevalence of malnutrition, risk of malnutrition and well-nutrition was 12.5%, 52.4% and 35.1% respectively. In the multivariate model, hypertension (adjusted OR = 1.71; 95% CI: 1.02, 2.89), alcohol consumption (aOR = 4.06; 95% CI: 1.17, 14.07), and increased age (aOR = 1.06; 95% CI: 1.01, 1.11) were positively associated with malnutrition. An increased number of people living with the older person (aOR: 0.91; 95% CI: 0.85, 0.97) was a protective factor among those at risk for malnutrition.

    CONCLUSION: Both the prevalence of malnutrition and risk of malnutrition were commonly observed among community-dwelling older persons in Sri Lanka. The associated factors identified in this study might help public health professionals to implement necessary interventions that improve the nutritional status of this population.
