The detection of allergen types is very helpful in allergic rhinitis (AR) management. Some methods had been performed to examinethe specific IgE due to HDM such as ELISA and immunoblot methods. The aim of this research is to know the difference of specificIgE diagnostic value due to HDM between ELISA and immunoblot in allergic rhinitis method which is expected to be used as in vitroalternative method which is safe, fast, effective, with a high sensitivity and specificity by provement. The samples were allergic rhinitisand non-allergic rhinitis patients at ENT of Head and Neck Out patients Clinic of Dr. Soetomo Hospital Surabaya. The sera was examinedfor specific IgE due to HDM by ELISA and immunoblot methods and then analyzed for its diagnostic value using the 2 x 2 table with a95% confidence interval. The comparation between both methods were analyzed with Wilcoxon test. The diagnostic value of the specificHDM IgE with immunoblot method showed sensitivity of 90% and 80% specificity, positive predictive value 90% and the negative 80%and diagnostic efficiency 86.67%. The positive likelihood ratio 4.5 and the negative one 0.125. The diagnostic value of the specific IgEHDM/D.p with ELISA showed a sensitivity of 75% and specificity 75%, the positive predictive value 85.71% and the negative one 0%and diagnostic efficiency 75%. The positive likelihood ratio was 3 and the negative one 0.33. The diagnostic value of the specific IgEHDM with immunoblot showed a sensitivity of 90% and specificity 80%, the positive predictive value 90% and the negative one 80%and the diagnostic efficiency 86.67%. The positive likelihood ratio was 4.5 and the negative one 0.125. The difference of diagnostic valuein both methods revealed that the p value was 0.013. It can be concluded in this study that there was a significant difference of specificIgE due to HDM between ELISA and immunoblot methods in allergic rhinitis.

Introduction: During the past decades there has been a great progress in neuroimaging methods. Cranial computed tomography is part of the daily routine now and its use allows a fast diagnosis of parenchymal hemorrhage. However, before the availability of computed tomography the differentiation between ischemic and hemorrhagic stroke was based on patient history, physical examination, percutan angiography and cerebrospinal fluid sampling, and the clinical utility could be evaluated by autopsy of deceased patients. Aim: The authors explored the diagnostic performance of cerebrospinal fluid examination for the diagnosis of ischemic and hemorrhagic stroke. Method: Data of 200 deceased stroke patients were retrospectively evaluated. All patients had liquor sampling at admission and all of them had brain autopsy. Results: Bloody or yellowish cerebrospinal fluid at admission had a positive predictive value of 87.5% for hemorrhagic stroke confirmed by autopsy, while clear cerebrospinal fluid had positive predictive value of 90.7% for ischemic stroke. Patients who had clear liquor, but autopsy revealed hemorrhagic stroke had higher protein level in the cerebrospinal fluid, but the difference was not statistically significant (p = 0.09). Conclusions: The results confirm the importance of pathological evaluation of the brain in cases deceased from cerebral stroke. With this article the authors wanted to salute for those who contributed to the development of the Hungarian neuropathology. In this year we remember the 110th anniversary of the birth, and the 60th anniversary of the death of professor Kálmán Sántha. Professor László Molnár would be 90 years old in 2013. Orv.

Component-resolved diagnostics (CRD) in food allergies is an approach utilized to characterize the molecular components of each allergen involved in a specific IgE (sIgE)-mediated response. In the clinical practice, CRD can improve diagnostic accuracy and assist the physician in many aspects of the allergy work-up. CRD allows for discriminatory co-sensitization versus cross-sensitization phenomena and can be useful to stratify the clinical risk associated with a specific sensitization pattern, in addition to the oral food challenge (OFC). Despite this, there are still some unmet needs, such as the risk of over-prescribing unnecessary elimination diets and adrenaline auto-injectors. Moreover, up until now, none of the identified sIgE cutoff have shown a specificity and sensitivity profile as accurate as the OFC, which is the gold standard in diagnosing food allergies. In light of this, the aim of this review is to summarize the most relevant concepts in the field of CRD in food allergy and to provide a practical approach useful in clinical practice.
