Background. Oral allergy syndrome (OAS) is defined as immediate IgE-mediated allergic reaction localized in the oral mucosa and developing after consuming raw fruits, vegetables, nuts, legumes in pollen sensitized patients. Objective. To study the prevalence of OAS in children in the Tomsk region. Material. The cross-sectional study in random groups of primary schoolchildren aged 7-10 years (n=13 010) from the Tomsk region, Russia, was performed in frames of (EuroPrevall, № FP6-2006-TTC-TU-5 Proposal 045879). During the screening phase a survey with standardized questionnaire was carried out. Clinical stage (n=1288) included clinical interviewing with parents/guardians, the clinical examination of patients, skin prick testing with extracts of food and pollen allergens (ALK-Abello, Spain), measurement of specific IgE level in serum to food and pollen allergens, component resolved diagnostics (ImmunoCAP, Phadia, Sweden). Results. OAS registered in 13,71% of children with pollen sensitization. The main triggers were apples, carrots, peaches, peanuts. Main cause of OAS in the Tomsk region was cross-reactivity to Bet v 1 - homologues belonging to PR-10 family: to apple - Mal d 1 (r=0,92; p=0,01); to peach - Pru p1 (r=0,87; p=0,01); to peanut - Ara h 8 (r=0,74; p=0,01); to hazelnut - Cor a 1 (r=0,76; p=0,01); to carrot - Dau c 1 (r=0,54; p=0,01). Conclusion. OAS was observed in 13,71% of children with pollen sensitization and was developesed due to crossreactivity to the birch allergen Bet v 1.

Objective. The aim of this study was to research a sIgE allergen profile of birch pollen and to evaluate a contribution of some homologous food allergens as well as latex allergen to the development of sensibility in allergic rhinitis (AR) / rhinoconjunctivitis patients, in focus of cross-reactivity and oral allergy syndrome.. Methods. Blood sera of 21 AR/rhinoconjunctivitis patients (at the age of 3 to 16) and 20 healthy persons without allergy symptoms were used. sIgE to birch pollen, soybean, latex, apple and celery as well as the total IgE levels were measured by the ImmunoCAP method (Phadia, Sweden) and the ELISA kits (Alkorbio, Russia). Results. We detected high total IgE levels, sIgE to allergens of birch pollen, apple, celery, as well as to recombinant allergens of birch Bet v 1, Bet v 2 and soybean - Gly m 4 in AR patients. Correlation analysis of IgE humoral response to homologous proteins showed the direct valid dependence between the sIgE levels to birch isoallergen Bet v 1 and soy isoallergen Gly m 4 (r=0,84; p

Diseases caused by flaviviruses, including dengue fever and Japanese encephalitis, are major health problems in Vietnam. This cross-sectional study explored the feasibility of domestic dogs as sentinels to better understand risks of mosquito-borne diseases in Hanoi city. A total of 475 dogs serum samples from 221 households in six districts of Hanoi were analyzed by a competitive enzyme-linked immunosorbent assay (cELISA) for antibodies to the pr-E protein of West Nile virus and other flaviviruses due to cross-reactivity. The overall flavivirus seroprevalence in the dog population was 70.7% (95% CI = 66.4–74.8%). At the animal level, significant associations between seropositive dogs and district location, age, breed and keeping practice were determined. At the household level, the major risk factors were rural and peri-urban locations, presence of pigs, coil burning and households without mosquito-borne disease experience (p < 0.05). Mosquito control by using larvicides or electric traps could lower seropositivity, but other measures did not contribute to significant risk mitigation of flavivirus exposure in dogs. These results will support better control of mosquito-borne diseases in Hanoi, and they indicate that dogs can be used as sentinels for flavivirus exposure.

Abstract Background Sudden cardiac arrest considers one of the most leading cause for death in all over the world. It is important for all medical students to train basic life support. This study evaluated the awareness of basic life support among medical students. Methods An electronic questionnaire based cross sectional study was conducted in November 2020 among 2114 medical student in Syria, Iraq and Jordan. We evaluated BLS skills according to mean score. A chi-squared test was used to determine if there were differences between those who attended a basic life support course and those who did not. Results 1656 of the participants (78.3%) stated that they did not attend a basic life support course. There was a significant difference between the participants from different countries where the mean score in Syria, Jordan and Iraq was 18.3, 24.3 and 18.8 respectively (p < 0.05). The participants were divided into 3 level according to total score; low (0–12), moderate (13–24) and high (25–37). In total, 18.3%, 72.8% and 8.9% of participants had high, intermediate and low level respectively. Conclusions The overall knowledge of basic life support among medical students is not adequate and need significant improvements. This study showed that an attendance a basic life support course previously had an effect on knowledge level. Hence, there is an urgent need to apply basic life support courses into the pre-clinical stage at universities.

Oral Allergy Syndrome (OAS) in patients with pollen-induced rhinoconjunctivitis is caused by specific IgE recognizing cross-reacting epitopes of fruits and plants, which were clearly shown in vitro, but failed to be demonstrated in vivo by cross-challenges in the target organs. Considering the hypothesis of degradation of such epitopes in natural extracts, challenges with recombinant pollen allergens were done to evaluate the reactivity of the oral mucosa in OAS patients. Seventeen patients with OAS and rhinitis from birch (10) and grass pollen (7) and 10 non-atopic controls were studied by skin prick tests (SPT), allergen specific nasal challenges (ASNC) and allergen specific sublingual challenges (ASSC) with birch and timothy extracts and with rBet v1 and rPhl p1 at increasing concentrations from 1 to 1000 mcg/ml. None of the healthy subjects in the control group had any positive test for birch and timothy extracts or for recombinant allergens. In the OAS group the following results were observed: SPTs with recombinant allergens were positive in all patients, mostly at 10 mcg/ml concentration; ASNC with rBet v1 were positive in all patients, mostly at 100 mcg/ml; ASSC with natural pollen extracts were positive in only 2 of 17 patients, but in 15 of 17 with rBet v1 and rPhl p1, mostly at 500 mcg/ml and 1000 mcg/ml. ASSC with rBet v1 and rPhl p1 were positive with a mean concentration of 677 and 533 mcg/ml, respectively. The results of sublingual challenges with rBet v1 and rPhl p1 showed the in vivo cross-reactivity between pollens and foods in patients with OAS, but high concentrations of the recombinant allergens were needed to reproduce oral symptoms, thus explaining the failure of challenges performed with natural extracts, which have concentrations of major allergens lower than 50 mcg/ml. This indicates that sublingual mucosa is much less reactive to allergens than other surfaces, such as skin and nasal mucosa, probably because of its anatomic and immunologic peculiarity.

Background. Cognitive impairment among human immunodeficiency virus (HIV) infected patients can lead to treatment nonadherence, faster progression of the illness, disability, and bed ridden state if we fail to detect it early. However, there is scarcity of previous published studies in Ethiopia on the assessment of cognitive impairment among HIV-positive patients. Hence, this study aimed to determine the prevalence and associated factors of cognitive impairment among HIV-positive patients receiving antiretroviral therapy (ART) at Jimma University Medical Center, Ethiopia. Methods. Hospital-based cross-sectional study was conducted among 328 HIV-positive patients attending Jimma University Medical Center, Ethiopia. Data were collected from a face-to-face interview and review of medical records using semistructured questionnaire. Validated International HIV Dementia Scale (IHDS) was used to screen for cognitive impairment. Data was analyzed using SPSS version 20. Results. A total of 328 (191 females and 137 males) HIV-positive patients were included in the study with a response rate of 97.04%. The prevalence of cognitive impairment among HIV-positive patients was 35.7%. Factors significantly associated with cognitive impairment were age group of 41−64 years (adjusted odds ratio [AOR] = 3.1, 95% confidence interval [CI] (1.3, 7.4)], plasma HIV-1 RNA load between 1.7log10 and 3log10 copies/ml [AOR = 2.2, 95% CI (1.1,4.3)] and ≥ 3log10 copies/ml [AOR = 7.5, 95% CI (2.6, 21.5)], khat chewing [AOR = 4.4, 95% CI (2.3, 8.3)], and clinical stage III of the disease [AOR = 5.6, 95% CI (1.7, 19.2)]. Conclusion. Despite the use of ART, the burden of cognitive impairment among HIV patients was high. Older age, khat chewing, advanced stage of the disease, and higher viral load were the independent factors associated with cognitive impairment. Thus, continuous screening of cognitive impairment, identification of the possible risk factors, and proper management strategy should be designed.

Background: Cervical cancer is a disease which claims maximum number of deaths in developing countries. Objective of this study was to understand the reason for delayed approach to medical help in women with advanced carcinoma cervix.Methods: It was a cross-sectional study. Information obtained from women with carcinoma cervix clinical stage IIb and above with proven histopathological diagnosis was recorded in the predetermined format.Results: Almost all the subjects were illiterate and were from lower socioeconomic strata and rural areas. None of them knew about the disease and its symptomatology. About 82% of the patients were symptomatic since 5-10 years however took no medical care during the period and 2/3rd of them even did not reveal their problem to any of the family members. About 79% of the subjects had never used any contraception and none had knowledge about its role in preventing infection. Majority of them (98%) had no idea about the role of PAP smear in screening carcinoma cervix. All of them said if they had knowledge about the disease, they would have sought medical help much earlier.Conclusions: The most important reason for delayed approach in our study was found to be lack of knowledge about the disease. Therefore, till such time that we have national screening program in place, these women who are at high risk of developing carcinoma of cervix should be targeted and educated through mass media so that these women could seek medical help in early stages.

Summary: Our objective was to propose a strategy to screen HIV infected African people for biological immunodeficiency easily. In a cross sectional study, we analysed the patterns of diseases and of CD4 counts among 266 HIV infected adults. Peripheral facial paralysis and chronic cutaneo mucous diseases were the earlier B stage diseases. Pulmonary tuberculosis was close to B stage diseases, and chronic diarrhoea was borderline between B and C stages. Cachexia was the most frequent C stage symptom 47.8 . Ninety per cent of CDC C stage people had CD4 counts below 350 mul, whereas only 75 had CD4 counts below 200 mul. Regression analysis identified the lymphocyte count, clinical stage and platelet count as predictors of CD4 count below 350 mul. A simple score lymphocyte count 2500 mul and clinical stage B is proposed to determine this CD4 threshold positive predictive value: 83 and to determine those patients needing treatment to prevent wasting and opportunistic infections.

ObjectivesExposure to farm environments during childhood and adult life seems to reduce the risk of atopic sensitisation. Most studies have been conducted among farmers, but people living in rural areas may have similar protective effects for atopy. This study aims to investigate the association between residential proximity to livestock farms and atopy among non-farming adults living in a rural area in the Netherlands.MethodsWe conducted a cross-sectional study among 2443 adults (20–72 years). Atopy was defined as specific IgE to common allergens and/or total IgE ≥100 IU/mL. Residential proximity to livestock farms was assessed as 1) distance to the nearest pig, poultry, cattle or any farm, 2) number of farms within 500 m and 1000 m, and 3) modelled annual average fine dust emissions from farms within 500 m and 1000 m. Data were analysed with multiple logistic regression and generalised additive models.ResultsThe prevalence of atopy was 29.8%. Subjects living at short distances from farms (<327 m, first tertile) had a lower odds for atopy compared with subjects living further away (>527 m, third tertile) (OR 0.79, 95% CI 0.63 to 0.98). Significant associations in the same direction were found with distance to the nearest pig or cattle farm. The associations between atopy and livestock farm exposure were somewhat stronger in subjects who grew up on a farm.ConclusionsLiving in close proximity to livestock farms seems to protect against atopy. This study provides evidence that protective effects of early-life and adult farm exposures may extend beyond farming populations.

Abstract Background Periplaneta americana and Blattella germanica cockroaches are widespread, and risk of sensitization increases in urban environments where these roaches thrive as household pests. There are no prior reports of Blaptica dubia cockroach allergy, though human exposure to B. dubia is increasing through commercial breeding as feeder insects. Case presentation A 50-year-old B. dubia cockroach breeder presented with progressively worsening upper and lower respiratory symptoms in recent years. Symptoms were worse with exposure to her B. dubia roach colony. Skin prick testing (SPT) to B. dubia cast skin, internal organs, and feces was performed in both the subject and a human control. Testing for P. americana and B. germanica sensitization was also performed in the subject. SDS–Polyacrylamide gel electrophoresis (PAGE), immunoblots, and enzyme-linked immunosorbent assays (ELISA) studies were performed using the subject and control serums to explore for specific IgE binding to B. dubia as well as P. americana. Our results showed SPT was positive to B. dubia internal organs in the subject and negative in the control. In the subject, SPT was negative to P. americana though intradermal (ID) testing was positive and serum specific IgE (sIgE) testing was negative to B. germanica. Immunoblotting of the subject's serum to B. dubia internal organ extract showed several distinct bands of IgE binding at 47 kilodaltons (kD), 68 kD, 74 kD, 83 kD, and 118 kD. The strongest band was at 118 kD on B. dubia immunoblotting, which was absent in P. americana on SDS-PAGE. ELISA studies showed an increased IgE response to both B. dubia and P. americana in the subject versus the control. Conclusions This case confirmed the first reported allergy to B. dubia cockroaches. There may be cross-reactivity between B. dubia and P. americana, though our case suggests SPT and sIgE testing using P. americana and B. germanica extract has potential to miss a B. dubia cockroach allergy. This allergy is likely underreported, and further study is needed to explore the natural history of B. dubia cockroach allergy.

BACKGROUND: Colorectal cancer is the third most common among malignant neoplasms worldwide. Treatment choice depends on the location of the tumor, among other factors, and varies from local excision to abdominoperineal resection, adjuvant or neoadjuvant therapy can be needed, depending on clinical stage. The purpose of this study was to determine the most common histological type of rectal cancer, establish the most frequent clinical stage at diagnosis, the most common surgical technique and complications. METHODOLOGY: A cross-sectional study was carried out, with 160 patients treated in the digestive surgery service of Hospital SOLCA, Guayaquil – Ecuador, between January 2011 and December 2016, with colorectal cancer histologically diagnosed and treated surgically. RESULTS: Female sex was the most affected, with 65.7%, 63.1% of the patients were diagnosed at stage III, adenocarcinoma was the most common histological type (73.7%), the tumor was more frequently located at a low level, in 67.5% of the patients. Surgery was scheduled for 83.7% of the patients, derivative colostomy was the most common surgical procedure for treatment (48.8%), and the most common complications were those related to the ostomy, in 9.4% of the patients. Immediate mortality was 1.2% and late mortality was 8.1%. CONCLUSION: This study evidenced that colorectal cancer affected with more frequency to women, mainly to people over 60 years old. Most of the patients were diagnosed with advanced clinical stage (III) carcinoma, most frequently adenocarcinoma. Derivative colostomy was the procedure of choice for most of the patients, most of them needed neoadjuvant therapy too. The most common postsurgical complications were those related to ostomies.
