RESUMO
BACKGROUND: Most infectious diseases result from a lack of knowledge and poor personal hygiene. Hand hygiene, in particular, is one of the most common means by which pathogens are transmitted. The aim of this study was to determine college student's knowledge and awareness of personal hygiene in Kuwait. MATERIALS AND METHODS: A multi-dimensional health assessment approach was followed using a self-administered questionnaire that was distributed among students of two colleges (the College of Nursing and the College of Health Sciences). Item analysis was conducted on 33 items of the questionnaire and measure five types of hygiene practices: hand hygiene, body hygiene, special hair application, oral care, and clothes hygiene. The data collected in the questionnaires and results were analyzed using statistical software SPSS version 23. Statistical analysis was performed using ANOVA and Student's t-test. Internal consistency, reliability was good, with an overall Cronbach's Alpha value of 0.749. RESULTS: Most respondents were female with 64%, while 80% of the college students were in the age of <20-year-old. Twelve items were underhand hygiene practices, and four items under body hygiene. Nine items were under oral care; three, items were under hair application. Three were under clothes hygiene. CONCLUSIONS: This study showed that female students had a better knowledge and were more hygienic in hand hygiene, hair application, and body hygiene whereas, male students showed a better oral hygiene practice. Nevertheless, this study shows that the hygiene questionnaire is an acceptable and reliable measure of awareness and practice among college students.
RESUMO
Mycoplasma infection is a major problem in veterinary medicine and in poultry production. The pathogen has many strains, so that diagnosis of the disease using culture method is not effective. The objective of this work was to evaluate the prevalence of Mycoplasma gallisepticum (MG) in Kuwait poultry farms using serology and molecular methods in comparison to the culture under specific conditions. A total of 50 swab samples from choanal cleft and tracheal samples and blood samples were obtained from three different local farms, the blood samples were processed for an Enzyme Linked Immunosorbent Assay (ELISA) detection and the swab samples for Polymerase Chain Reaction (PCR) and culture methods detection. A PCR diagnostic kit (VenoMGs) and ELISA diagnostic kit (ProFLOK), were used in comparison to the traditional culture method, to study the spread of this disease in samples from broiler and layer flocks. Fifty chicken samples were tested for mycoplasmosis, samples tested with ELISA gave 24 positive (48%) and 29 were positive by PCR (58%) and only seven (14%) were positive with culture methods. Swab samples obtained from the choanal cleft gave more positive (60%) with PCR than tracheal samples (56.6%). The culture gave 20 and 5% positive, respectively for tracheal and choanal samples. The methods reported here are of high sensitivity and specificity for Mycoplasma. Both the PCR and ELISA methods are superior to culture method for detection of avian mycoplasmosis. This study showed that MG infection is prevalent in commercial broiler and layer chickens in Kuwait poultry farms. The use of these methods for surveillance of the disease will establish data concerning the predominant Mycoplasmosis diseases in Kuwait if done on a large scale.

Laboratory detection of Brucella is based largely on bacterial isolation and phenotypic characterization. These methods are lengthy and labor-intensive and have been associated with a heightened risk of laboratory-acquired infection. Antibody based indirect detection methods also suffer from limitations in proper diagnosis of the organism. To overcome these problems, nucleic acid amplification has been explored for rapid detection and confirmation of the presence of Brucella spp. PCR-based diagnostics is useful for screening large populations of livestock to identify infected individuals and confirms the presence of the pathogen. Random Amplification of Polymorphic DNA (RAPD) was performed and identified a 1.3 kb PCR fragment specifically amplifiable from DNA isolated from Brucella. A BLAST search revealed no significant homology with the reported sequences from species other than the members of Brucella. The isolated fragment seems to be a part of d-alanine-d-alanine ligase gene in Brucella sp. Translational BLAST revealed certain degree of homology of this sequence with orthologs of this gene reported from other microbial species at the deduced amino acid level. The sequence information was used to develop PCR based assays to detect Brucella sp. from various samples. The minimum detection limit of Brucella from blood and milk samples spiked with Brucella DNA was found to be 1 ng/ml and 10 ng/ml, respectively. In conclusion, we demonstrated that the PCR based detection protocol was successfully used for the detection of Brucella from various organs and spiked samples of diseased sheep. Diagnosis of Brucellosis by PCR based method reported in this study is relatively rapid, specific and simple.
RESUMO
BACKGROUND: Respiratory infections are known to exacerbate wheezing in many asthmatic patients. We aimed to use molecular methods for the fast detection of Mycoplasma pneumoniae, Chlamydia pneumoniae and Legionella pneumophila in respiratory specimens from asthmatic patients in Kuwait. METHODS: We used uniplex PCR assays to detect the three atypical bacteria in clinical specimens from 235 asthmatic and non-asthmatic patients in Kuwait. A regression analysis was used to identify the risk factors related to the bacterial type. Group comparisons for similarity were conducted and correlation coefficients were calculated using SPSS statistical software. RESULTS: The detection limits using uniplex PCR for C. pneumoniae, L. pneumophila and M. pneumoniae were approximately 1pg, 2.4fg and 12pg of DNA, respectively. M. pneumoniae PCR positivity was more common in asthmatic patients (15%) than in non-asthmatic subjects (9%) (P<0.05). A marked difference was observed between patients with acute asthma exacerbation (11%) and patients with chronic (stable) asthma (7%) among Kuwaiti patients; these percentages were 16% for non-Kuwaiti acute asthma patients and 14% for non-Kuwaiti chronic asthma patients (P<0.201). There was a weak positive correlation between asthma severity and PCR positivity for M. pneumoniae. The PCR results for C. pneumoniae and L. pneumoniae were found to be statistically insignificant. CONCLUSIONS: The results of this study suggest that infection with M. pneumoniae may be related to the exacerbation of asthma symptoms and could possibly be a factor that induces wheezing.

OBJECTIVE: The aim of this study was to screen for diabetes mellitus in leprosy patients to elucidate whether leprosy infection may play a role in the pathogenesis of diabetes mellitus in this population. SUBJECTS AND METHODS: Thirty patients of different ages and of both sexes with various types of leprosy were included in this study. In addition, 15 healthy individuals of comparable age and sex who had no family history of diabetes mellitus were identified as controls. In both groups, determinations of fasting and postprandial blood sugar, an oral glucose tolerance test (OGTT), measures of fasting serum insulin and pro-inflammatory cytokine tumor necrosis factor alpha (TNFα), as well as calculations using the Homeostasis Model Assessment for Insulin Resistance (HOMA-IR), were carried out. RESULT: Approximately 13.3% of the leprosy patients were diabetic, and 37.7% were in pre-diabetic. The highest incidences of diabetes and pre-diabetes were in lepromatous leprosy (10% and 20%, respectively); a lower incidence of pre-diabetes (6.6%) was observed in tuberculoid leprosy; and the lowest incidence of diabetes (0.0%) was noted in borderline leprosy patients. Although normal healthy persons were not diabetic (0%), 20% were pre-diabetic. CONCLUSION: This study revealed that the incidence of diabetes was higher in the leprosy patients than in the control group. As a result, we recommend that all leprosy patients should be screened for diabetes.

BACKGROUND: We investigated the association between apolipoprotein E polymorphism and ischemic heart disease with or without type 2 diabetes in Kuwait and examined the impact of apolipoprotein E polymorphism in diabetic patients. METHODS: The present study was conducted from January 2005 to June 2006 in the Diabetic Clinic of Al-Amiri and Al-Sabah Hospitals in Kuwait City. Apolipoprotein E polymorphism was assessed in 250 subjects of which 83 were ischemic heart disease patients (41 diabetic and 42 non-diabetic) and 105 were diabetic patients without ischemic heart disease. Results were compared with 62 healthy controls. Apolipoprotein E polymorphisms were detected by polymerase chain reaction-restriction fragment length polymorphism. RESULTS: Apolipoprotein E3 allele was the most commonly occurring form. The frequency of apolipoprotein E4 was higher in ischemic heart disease patients with type 2 diabetes (39%) and the non-diabetic (31%) group, but lower in the diabetic (20%) and control groups (16%). CONCLUSION: Apolipoprotein E4 allele may be related to the development of ischemic heart disease in patients with or without type 2 diabetes in Kuwait. However, future studies with larger population sizes are needed to establish such relationship.

BACKGROUND: The increasing prevalence of asthma in many countries has been related to weather factors and aeroallergen concentrations, but this has not been studied in Kuwait. We evaluated the effect of meteorological factors and the occurrence of aerobiologicals on the number of asthma cases in Kuwait. METHODS: The number of daily asthma visits to the allergy center and emergency department at Al-Sabha Hospital for 1 year were examined on a monthly basis for correlation with major metereological factors (temperature, relative humidity, rain, wind speed and direction). Spore and pollen counts were collected hourly. RESULTS: A total of 4353 patients received asthma treatment during the year. The highest pollen count was in the month of September with a maximum relative humidity of 47% and no precipitation, but with a high mean temperature of 39.7 degrees C. Pollen counts were higher in the late summer (September) and occurred with a high patient visit to the allergy center. Fungal spore counts were significantly higher in early winter (December). The high fungal spore count seemed related to with high relative humidity and high precipitation with a low mean average temperature of 19.7 degrees C. The increase number of patients with bronchial asthma visiting an emergency clinic during December was significantly associated with high aerial counts for fungal spores (P<.03), and the months of September and October were more significant for pollen. CONCLUSION: This study indicates that meteorological factors, aeroallergen concentrations and asthma-related visits are interrelated. The results may prove useful in the generation of hypotheses and development of designs for more comprehensive, individual-based epidemiological studies.
