    Running amok is considered a rare but dangerous act of violence which has been investigated predominantly on a case by case basis. German-wide data on amok cases covering the decades 1980 - 1989 and 1991 - 2000 were used to perform the first epidemiological study world-wide on the stability of socio-demographic, criminological and psychiatric variables of amok behaviour.

    The molecular genetic analysis of the genomes of the virus of porcine reproductive respiratory syndrome (VPRRS) and porcine circovirus type 2 (PCV-2) circulating in the area of the Russian Federation was discussed. The results of this work showed the circulation of the strains of the European genotype VPRRS similar to those found in France and Denmark from 1998 to 2001. The homology of the fragment of one of the genes between the Russian isolates and the vaccine strain Porcilis PRRS (Intervet) was found. It requires further study. The strains representing the North American genotype VPRRS were not found. The PCV-2 genomes fall into three separate goups. One (genotype 2b) is formed by isolates in Malaysia, Brazil, Switzerland, China, Slovakia, UK, USA, isolated during the period from 2004 to the present time. The second group consists of sequences of the viruses isolated in 2000-2012 in Canada, the U.S., China, and South Korea (genotype 2a). The third group is formed by highly pathogenic isolates in 2013 from China (highly pathogenic genotype 2c). The circulation of all three known genotypes of PCV-2: 2a, 2b, and 2c in Russian Federation was demonstrated.

    In 2016, we have seen a rapid emergence of Zika virus-associated Guillain-Barré syndrome (GBS) since its first description in a French-Polynesian patient in 2014. Current evidence estimates the incidence of GBS at 24 cases per 100 000 persons infected by Zika virus. This will result in a sharp rise in the number of GBS cases worldwide with the anticipated global spread of Zika virus. A better understanding of the pathogenesis of Zika-associated GBS is crucial to prepare us for the current epidemic. In this review, we evaluate the existing literature on GBS in association with Zika and other flavivirus to better define its clinical subtypes and electrophysiological characteristics, demonstrating a demyelinating subtype of GBS in most cases. We also recommend measures that will help reduce the gaps in knowledge that currently exist.

    BACKGROUND: Chronic granulomatous disease (CGD) is a rare primary immunodeficiency (PID) caused by a dysfunctional respiratory burst enzyme NADPH-oxidase. The concurrence of Klinefelter’s Syndrome (KS) and CGD would be extremely rare.
    OBJECTIVE: We describe the study of a family where the youngest male child had X-linked CGD (X-CGD) while his older brother was both an X-CGD carrier and a Klinefelter.
    METHODS: Flow cytometry was used to study respiratory burst and gp91-phox expression, while genetic investigation was done by RT-PCR, PCR and X-chromosome short tandem repeat (X-STR) analysis.
    RESULTS: The Dihydrorhodamine (DHR) assay showed the patient’s neutrophils failed to produce a respiratory burst, while both the mother and an older brother showed a bimodal response. gp91-phox expression was absent in the patient’s neutrophils, and bimodal in the mother’s and brother’s neutrophils. The patient’s cDNA showed a C>T change at nucleotide 676 of the CYBB gene. The same change was seen in the patient’s gDNA, while the brother and mother were heterozygous, with C and T, in this position. The c.676C>T is a nonsense mutation that leads to premature termination of the gp91-phox protein. The brother karyotyped as 47, XXY and X chromosome analysis showed that he had inherited both his mother’s X chromosomes.
    CONCLUSIONS: This study showed that the patient had gp91-phox deficient CGD while his older brother was a CGD carrier and a Klinefelter, who had inherited both his mother’s X chromosomes. This is the first report of such a concurrence in an individual, and argues for family members to be included in PID studies.

    Work-related musculoskeletal disorders of the upper limb (WRMSDs-UL) account for one of the largest types of occupational disorders worldwide. This broad term includes several disorders, such as carpal tunnel syndrome, tendonitis, tension neck syndrome and lateral epicondylitis (tennis elbow) which are generally caused by poor postures, repetitive strain and psychosocial factors. Various workplace interventions have been investigated and employed to prevent the different WRMSDs-UL, but a common consensus to address the problem has yet to be achieved. This paper reviews and discusses the efficacies of some interventions which have been tested for the most prevalent type of WRMSDs-UL, carpal tunnel syndrome (CTS). The focus will be on computer users who developed CTS out of the prolonged and repetitive use of keyboards and pointing devices. The interventions studied include engineering design, management strategies, personal development, medical treatment and multi-dimensional approaches. Outcome of the study reveals that the most effective approach would be one that is multi-dimensional in nature, with the inclusion of at least two or more intervention strategies at the same time.

    Metabolic syndrome has been associated with an increased risk of cardiovascular disease and diabetes mellitus. The objective of this study was to determine gender differences in the prevalence and factors associated with metabolic syndrome in a rural Malay population. This cross-sectional study, conducted in Bachok, Kelantan, involved 306 respondents aged 18 to 70 years. The survey used a structured questionnaire to collect information on demographics, lifestyle, and medical history. Anthropometric measurements, such as weight, height, body mass index, waist and hip circumference, and blood pressure were measured. Venous blood samples were taken by a doctor or nurses and analyzed for lipid profile and fasting glucose. The overall prevalence of metabolic syndrome was 37.5% and was higher among females (42.9%). Being unemployed or a housewife and being of older age were independently associated with metabolic syndrome in a multivariate analysis. Weight management and preventive community-based programs involving housewives, the unemployed, and adults of poor education must be reinforced to prevent and manage metabolic syndrome effectively in adults.

    Williams-Beuren syndrome (WBS) is a common microdeletion syndrome characterized by a 1.5Mb deletion in 7q11.23. The phenotype of WBS has been well described in populations of European descent with not as much attention given to other ethnicities. In this study, individuals with WBS from diverse populations were assessed clinically and by facial analysis technology. Clinical data and images from 137 individuals with WBS were found in 19 countries with an average age of 11 years and female gender of 45%. The most common clinical phenotype elements were periorbital fullness and intellectual disability which were present in greater than 90% of our cohort. Additionally, 75% or greater of all individuals with WBS had malar flattening, long philtrum, wide mouth, and small jaw. Using facial analysis technology, we compared 286 Asian, African, Caucasian, and Latin American individuals with WBS with 286 gender and age matched controls and found that the accuracy to discriminate between WBS and controls was 0.90 when the entire cohort was evaluated concurrently. The test accuracy of the facial recognition technology increased significantly when the cohort was analyzed by specific ethnic population (P-value

    In the light of present HIV worldwide epidemic. there is a need to teach the busy general practitioners how to recognise HIV & AIDS. Due to the deadly nature of this infection and its manifold presentations from opportunistic diseases. the busy general practitioners in primary care may be misled in making the correct diagnosis. In Malaysia. the doctors in the primary care level constitute 70 to 75% of the doctors' population. The rest are specialists in secondary and tertiary care institutions. Family Physicians from the Font liners to recognise and detect early cases of HlV in all its early manifestalions on the various systems. Any doctors in primary medicine whether from private or public sector, amy be confronted by patients who present with trivial complaints. These patients may be fee-paying, or particularly those doctors involved with welfare and health of factory workers and the other forms of the main work force should well arm themselves with updates in HIV and AIDS.

    The Li-Fraumeni syndrome (LFS) and its variant form (LFL) is a familial predisposition to multiple forms of childhood, adolescent, and adult cancers associated with germ-line mutation in the TP53 tumor suppressor gene. Individual disparities in tumor patterns are compounded by acceleration of cancer onset with successive generations. It has been suggested that this apparent anticipation pattern may result from germ-line genomic instability in TP53 mutation carriers, causing increased DNA copy-number variations (CNVs) with successive generations. To address the genetic basis of phenotypic disparities of LFS/LFL, we performed whole-genome sequencing (WGS) of 13 subjects from two generations of an LFS kindred. Neither de novo CNV nor significant difference in total CNV was detected in relation with successive generations or with age at cancer onset. These observations were consistent with an experimental mouse model system showing that trp53 deficiency in the germ line of father or mother did not increase CNV occurrence in the offspring. On the other hand, individual records on 1,771 TP53 mutation carriers from 294 pedigrees were compiled to assess genetic anticipation patterns (International Agency for Research on Cancer TP53 database). No strictly defined anticipation pattern was observed. Rather, in multigeneration families, cancer onset was delayed in older compared with recent generations. These observations support an alternative model for apparent anticipation in which rare variants from noncarrier parents may attenuate constitutive resistance to tumorigenesis in the offspring of TP53 mutation carriers with late cancer onset.

    Microbiological analysis of samples collected from cases of white spot disease outbreaks in cultured shrimp in different farms located in three regions along East Coast of India viz. Chidambram (Tamil Nadu), Nellore (Andhra Pradesh) and Balasore (Orissa), revealed presence of Vibrio alginolyticus, Vibrio parahaemolyticus, and Aeromonas spp. but experimental infection trials in Penaeus monodon with these isolates did not induce any acute mortality or formation of white spots on carapace. Infection trials using filtered tissue extracts by oral and injection method induced mortality in healthy P. monodon with all samples and 100% mortality was noted by the end of 7 day post-inoculation. Histopathological analysis demonstrated degenerated cells characterized by hypertrophied nuclei in gills, hepatopancreas and lymphoid organ with presence of intranuclear basophilic or eosino-basophilic bodies in tubular cells and intercellular spaces. Analysis of samples using 3 different primer sets as used by other for detection of white spot syndrome virus (WSSV) generated 643, 1447 and 520bp amplified DNA products in all samples except in one instance. Variable size virions with mean size in the range of 110 x 320 +/- 20 nm were observed under electron microscope. It could be concluded that the viral isolates in India involved with white spot syndrome in cultured shrimp are similar to RV-PJ and SEMBV in Japan, WSBV in Taiwan and WSSV in Malaysia, Indonesia, Thailand, China and Japan.

    BACKGROUND: Most clinical guidelines recommend that AIDS-free, HIV-infected persons with CD4 cell counts below 0.350 × 10(9) cells/L initiate combined antiretroviral therapy (cART), but the optimal CD4 cell count at which cART should be initiated remains a matter of debate.

    OBJECTIVE: To identify the optimal CD4 cell count at which cART should be initiated.

    DESIGN: Prospective observational data from the HIV-CAUSAL Collaboration and dynamic marginal structural models were used to compare cART initiation strategies for CD4 thresholds between 0.200 and 0.500 × 10(9) cells/L.

    SETTING: HIV clinics in Europe and the Veterans Health Administration system in the United States.

    PATIENTS: 20, 971 HIV-infected, therapy-naive persons with baseline CD4 cell counts at or above 0.500 × 10(9) cells/L and no previous AIDS-defining illnesses, of whom 8392 had a CD4 cell count that decreased into the range of 0.200 to 0.499 × 10(9) cells/L and were included in the analysis.

    MEASUREMENTS: Hazard ratios and survival proportions for all-cause mortality and a combined end point of AIDS-defining illness or death.

    RESULTS: Compared with initiating cART at the CD4 cell count threshold of 0.500 × 10(9) cells/L, the mortality hazard ratio was 1.01 (95% CI, 0.84 to 1.22) for the 0.350 threshold and 1.20 (CI, 0.97 to 1.48) for the 0.200 threshold. The corresponding hazard ratios were 1.38 (CI, 1.23 to 1.56) and 1.90 (CI, 1.67 to 2.15), respectively, for the combined end point of AIDS-defining illness or death.

    LIMITATIONS: CD4 cell count at cART initiation was not randomized. Residual confounding may exist.

    CONCLUSION: Initiation of cART at a threshold CD4 count of 0.500 × 10(9) cells/L increases AIDS-free survival. However, mortality did not vary substantially with the use of CD4 thresholds between 0.300 and 0.500 × 10(9) cells/L.

    Despite being a large ethnic group within the South-East Asia, there is a paucity of reported literatures on dyspepsia in the Malay population. Recent population-based studies indicate that uninvestigated dyspepsia, based on the Rome II criteria, is reported in 12.8% and 11.6% of Malays in the urban and rural communities respectively. Organic causes of dyspepsia including upper gastrointestinal tract cancers, its precancerous lesions, and erosive diseases are uncommon which is largely due to an exceptionally low prevalence of Helicobacter pylori infection in this population. On the other hand, functional dyspepsia and irritable bowel syndrome are relatively common in the Malays than expected. Within a primary care setting, functional dyspepsia, based on the Rome III criteria, is reported in 11.9% of Malays, of which epigastric pain syndrome is found to be more common. Married Malay females are more likely to have functional dyspepsia and psychosocial alarm symptoms. Also based on the Rome III criteria, irritable bowel syndrome, commonly overlapped with functional dyspepsia, is reported in 10.9% of Malays within a community-based setting. Rather than psychosocial symptoms, red flags are most likely to be reported among the Malays with irritable bowel syndrome despite having a low yield for organic diseases. Based upon the above observations, "proton pump inhibitor test" is probably preferable than the "test and treat H. pylori" strategy in the initial management of dyspepsia among the Malays.

    Two cases of Wernicke's encephalopathy due to hyperemesis gravidarum are described. The first patient presented with bilateral papilloedema, altered sensorium and the second with bilateral retinal haemorrhages, ophthalmoplegia and nystagmus. Both patients were diagnosed with Wernicke's encephalopathy on clinical ground since there were no laboratory facilities to measure red cell transketolase and thiamine pyrophosphate levels. This is a rare but treatable complication of hyperemesis gravidarum (HG) and due to lack of diagnostic tools, there is often diagnostic uncertainty, delay in commencing appropriate treatment, as well as irreversible damage to the upper brain stem and death.

    We report a case of Wernicke's encephalopathy in a patient with nasopharyngeal carcinoma with a 3-month history of poor oral intake related to nausea and vomiting due to chemotherapy. The patient later developed deep coma while receiving in-patient therapy. Magnetic resonance imaging of the brain revealed typical findings of Wernicke's encephalopathy. The patient was treated with thiamine injections, which resulted in subsequent partial recovery of neurological function. This paper stresses the importance of magnetic resonance imaging for prompt diagnosis of Wernicke's encephalopathy.

    Background: Meteorological parameters and seasonal changes can play an important role in the occurrence of acute coronary syndrome (ACS). However, there is almost no evidence on a national level to suggest the associations between these variables and ACS in Iran. We aim to identify the meteorological parameters and seasonal changes in relationship to ACS. Methods: This retrospective cross-sectional study was conducted between 03/19/2015 to 03/18/2016 and used documents and records of patients with ACS in Mazandaran ProvinceHeart Center, Iran. The following definitive diagnostic criteria for ACS were used: (1) existence of cardiac enzymes (CK or CK-MB) above the normal range; (2) Greater than 1 mm ST-segment elevation or depression; (3) abnormal Q waves; and (4) manifestation of troponin enzyme in the blood. Data were collected daily, such as temperature (Celsius) changes, wind speed and its direction, rainfall, daily evaporation rate; number of sunny days, and relative humidity were provided by the Meteorological Organization of Iran. Results: A sample of 2,054 patients with ACS were recruited. The results indicated the highest ACS events from March to May. Generally, wind speed (18 PM) [IRR = 1.051 (95% CI: 1.019 to1.083), P=0.001], daily evaporation [IRR = 1.039 (95% CI: 1.003 to 1.077), P=0.032], daily maximum (P<0.001) and minimum (P=0.003) relative humidity was positively correlated withACS events. Also, negatively correlated variables were daily relative humidity (18 PM) [IRR =0.985 (95% CI: 0.978 to 0.992), P<0.001], and daily minimum temperature [IRR = 0.942 (95%CI: 0.927 to 0.958), P<0.001]. Conclusion: Climate changes were found to be significantly associated with ACS; especially from cold weather to hot weather in March, April and May. Further research is needed to fully understand the specific conditions and cold exposures.

    INTRODUCTION: Metabolic syndrome (MS) is a cluster of risk factors that increases the risk of cardiovascular disease and type 2 diabetes mellitus (DM). Waist circumference (WC), a surrogate indicator of abdominal fat mass, is used to measure central obesity associated with increased risk of hypertension, insulin resistance and type 2 DM, whereas body mass index (BMI) is traditionally used to measure somatic obesity. This study aimed to identify the WC and BMI cut-off points to predict the metabolic risk factors for MS and to determine which is a better predictor.
    METHODS: This was a cross-sectional study conducted over a period of six months. The study involved 355 subjects aged 13-91 years. Youden's index was used to identify the optimal cut-off points.
    RESULTS: The optimal cut-off point of WC to predict individual metabolic risk in females was 84.5-91.0 cm. The BMI cut-off point to predict hypertension and raised fasting blood sugar was 23.7 kg/m², and that for low level high-density lipoprotein cholesterol was 22.9 kg/m². For males, the corresponding cut-off points were 86.5-91.0 cm for WC and 20.75-25.5 kg/m² for BMI, with corresponding sensitivities and specificities. Area under the curve and the odds of developing individual and ≥ 2 metabolic risk factors for MS were higher for WC than for BMI.
    CONCLUSION: WC is a better predictor of metabolic risk factors for developing MS than BMI. Therefore, we propose that metabolic risk factors be screened when WC ≥ 80 cm is found in both genders regardless of BMI.

    Acute retinal necrosis (ARN) is a rare, blinding disease that typically affects adults. However, in this case report, we highlight the diagnosis, management and outcome of herpes simplex acute retinal necrosis in a 13-year-old healthy girl, who presented with painful right eye, redness and blurring of vision for one week. Examination of the right eye showed features of granulomatous panuveitis. Optic disc was swollen and retina appeared pale. There were multiple patches of retinitis and haemorrhages at mid-periphery of the fundus with inferior serous detachment observed. Rapidly progressive inflammation in just four days along with secondary cataract that obscured fundus view, imposed greater challenge to the diagnosis and management. Intravenous acyclovir 300mg, 3 times a day was initiated promptly while vitreous fluid was sent for polymerase chain reaction, which identified Herpes Simplex Virus-1. Inflammation improved, but she developed vitreous haemorrhage secondary to proliferative retinopathy, which required panretinal photocoagulation. ARN is therefore, principally a clinical diagnosis and high index of suspicion is crucial particularly, in children for prompt diagnosis and treatment. Complications should also be addressed timely to improve the chances of preserving vision.
