[Diagnosis and therapy of insect sting allergy]


[Over the past 20 years great progress has been made in understanding the pathogenesis, diagnosis and treatment of allergic reactions caused by insect stings. The incidence of insect sting allergy in a general population is about 0.4- 3% but anaphylaxis to Hymenoptera venom can be fatal. The diagnosis of venom allergy is based on the history suggesting an allergic reaction and on the demonstration of the persistence of specific IgE antibody either by skin tests or RAST. Patients who had a severe allergic reaction and has positive venom skin test or RAST result should be advised to receive venom immunotherapy (VIT). The risk for subsequent life-threatening systemic sting reactions can be significantly reduced with VIT. VIT should be continued for at least 3 to 5 years and provides about 90 % protection from insect sting anaphylaxis.]

[The connection between gastroesophageal reflux disease and obstructive sleep apnoea]

DEMETER Pál, VÁRDI Visy Katalin

[Clinical knowledge on the gastroesophageal reflux disease has been increased with the subject of extragastrointestinal complications in the last decade. Because of cardiological, pulmonological, laryngeal and dental complications, an interdisciplinary approach is required. The non-cardiac chest pain, bronchial asthma, chronic bronchitis, chronic caugh, posterior laryngitis and acidic damage of dental enamel are the most important complications. Authors study a less common connection between the gastroesophageal reflux disease and obstructive sleep apnoea. Sleeping can be considered as a risk factor of the reflux event by itself, because of the decrease of primary peristalsis, producing of saliva, and acidic and volume clearance of oesophagus as well. During obstructive sleep apnoea negative intrathoracic pressure increases extremely, resulting in increased transdiaphragmatic gradient of pressure as well. In addition, the powerful movement of diaphragm twitches the lower oesophageal sphincter through the phrenoesophageal ligament. These two mechanism practically promotes the reflux event in patients with obstructive sleep apnea. The new challenge for the gastroenterologists is to further research this new connection, to play more active role in the complex therapy, and to have a new diagnostic approach of serious gastroesophageal reflux disease.]

Although vertigo is one of the most common complaints, intracranial malignant tumors rarely cause sudden asymmetry between the tone of the vestibular peripheries masquerading as a peripheral-like disorder. Here we report a case of simultaneous temporal bone infiltrating macro-metastasis and disseminated multi-organ micro-metastases presenting as acute unilateral vestibular syndrome, due to the reawakening of a primary gastric signet ring cell carcinoma. Purpose – Our objective was to identify those pathophysiological steps that may explain the complex process of tumor reawakening, dissemination. The possible causes of vestibular asymmetry were also traced. A 56-year-old male patient’s interdisciplinary medical data had been retrospectively analyzed. Original clinical and pathological results have been collected and thoroughly reevaluated, then new histological staining and immunohistochemistry methods have been added to the diagnostic pool. During the autopsy the cerebrum and cerebellum was edematous. The apex of the left petrous bone was infiltrated and destructed by a tumor mass of 2x2 cm in size. Histological reexamination of the original gastric resection specimen slides revealed focal submucosal tumorous infiltration with a vascular invasion. By immunohistochemistry mainly single infiltrating tumor cells were observed with Cytokeratin 7 and Vimentin positivity and partial loss of E-cadherin staining. The subsequent histological examination of necropsy tissue specimens confirmed the disseminated, multi-organ microscopic tumorous invasion. Discussion – It has been recently reported that the expression of Vimentin and the loss of E-cadherin is significantly associated with advanced stage, lymph node metastasis, vascular and neural invasion and undifferentiated type with p<0.05 significance. As our patient was middle aged and had no immune-deficiency, the promoting factor of the reawakening of the primary GC malignant disease after a 9-year-long period of dormancy remained undiscovered. The organ-specific tropism explained by the “seed and soil” theory was unexpected, due to rare occurrence of gastric cancer to metastasize in the meninges given that only a minority of these cells would be capable of crossing the blood brain barrier. Patients with past malignancies and new onset of neurological symptoms should alert the physician to central nervous system involvement, and the appropriate, targeted diagnostic and therapeutic work-up should be established immediately. Targeted staining with specific antibodies is recommended. Recent studies on cell lines indicate that metformin strongly inhibits epithelial-mesenchymal transition of gastric cancer cells. Therefore, further studies need to be performed on cases positive for epithelial-mesenchymal transition.

[The majority of patients with advanced Parkinson’s disease are treated at specialized movement disorder centers. Currently, there is no clear consensus on how to define the stages of Parkinson’s disease; the proportion of Parkinson’s patients with advanced Parkinson’s disease, the referral process, and the clinical features used to characterize advanced Parkinson’s disease are not well delineated. The primary objective of this observational study was to evaluate the proportion of Parkinson’s patients identified as advanced patients according to physician’s judgment in all participating movement disorder centers across the study. Here we evaluate the Hungarian subset of the participating patients. The study was conducted in a cross-sectional, non-interventional, multi-country, multi-center format in 18 countries. Data were collected during a single patient visit. Current Parkinson’s disease status was assessed with Unified Parkinson’s Disease Rating Scale (UPDRS) parts II, III, IV, and V (modified Hoehn and Yahr staging). Non-motor symptoms were assessed using the PD Non-motor Symptoms Scale (NMSS); quality of life was assessed with the PD 8-item Quality-of-Life Questionnaire (PDQ-8). Parkinson’s disease was classified as advanced versus non-advanced based on physician assessment and on questions developed by the Delphi method. Overall, 2627 patients with Parkinson’s disease from 126 sites were documented. In Hungary, 100 patients with Parkinson’s disease were documented in four movement disorder centers, and, according to the physician assessment, 50% of these patients had advanced Parkinson’s disease. Their mean scores showed significantly higher impairment in those with, versus without advanced Parkinson’s disease: UPDRS II (14.1 vs. 9.2), UPDRS IV Q32 (1.1 vs. 0.0) and Q39 (1.1 vs. 0.5), UPDRS V (2.8 vs. 2.0) and PDQ-8 (29.1 vs. 18.9). Physicians in Hungarian movement disorder centers assessed that half of the Parkinson’s patients had advanced disease, with worse motor and non-motor symptom severity and worse QoL than those without advanced Parkinson’s disease. Despite being classified as eligible for invasive/device-aided treatment, that treatment had not been initiated in 25% of these patients.]

[Type 1 diabetes is generally believed to be be the result of an immune destruction of pancreatic ßcells in genetically susceptible individuals exposed to environmental risk factors. To study the epidemiology of childhood-onset type 1 diabetes mellitus in Europe, the EURODIAB collaborative group established in 1988 prospective geographicallydefined registers of new cases diagnosed under 15 years of age. The 10-year-old study shows a greater than 10-fold range in incidence rate of childhood diabetes in Europe. The standardised average annual incidence rate during the period 1989-1998 ranged from 3,6 cases per 100 000 per year in Macedonia to 43,9 cases per 100 000 per year in Finland. Combined data from all centres indicates that the annual rate of increase in incidence was 3,2% but in some central and eastern European countries it was higher. The age-group-specific rates of increase were 5% for children aged 0-4 years, 3,7% for 5-9 years, and 2,1% for 10-14 years, which shows that the highest rates of increase occurred in the youngest age group. The Hungarian Childhood Diabetes Registry has collected the data of all newly diagnosed children with type 1 diabetes aged 0-14 years since 1st January 1978. The standardised incidence rate during the period 1978-2002 was 8,6 cases per 100000 per year, the lowest in the youngest (0-4 yr), highest in the10-14-year-old-children. There was a linear increasing trend in incidence with the average rate of annual increase of 5,1%. Comparing our incidence rate with other European countries Hungary belongs to the medium-risk countries with similar age- and sex-specific incidence rates. The results of the EURODIAB study confirm a very wide range of incidence rates of childhood type 1 diabetes within Europe and show that the increase in incidence varies from country to country. Such variation seems to be unlikely to be explained by genetic differences, since Europeans (except some small populations) are more homogeneous compared with other populations of other continents. The rapid increase in incidence may be explained by changes in environmental factors.]

[A prospective study evaluating the clinical characteristics of cluster headache]


[Introduction - Although cluster headache (CH) is one of the most severe human pain syndromes, its symptoms and therapeutic possibilities may be suboptimally recognised in current medical practice in Hungary. Aim - To present the clinical characteristics of CH based on a prospective study of patients attending the Headache Service of the Department of Neurology, Semmelweis University. Methods - We collected information about the symptoms, diagnosis and previous treatment of CH patients by filling in a 108-item questionnaire during outpatient visits. Results - In the 5-year period between 2004 and 2008 we obtained data from 78 CH patients (57 males and 21 females; mean age: 44.6±14.6 years). The male:female ratio did not change in subgroups based on disease onset (calendar years). Ninety-three percent considered CH the most severe pain state of their life. The pain was strictly unilateral, affecting the territory of the 1st trigeminal division in all patients. The attacks were accompanied by signs of ipsilateral cranial parasympathetic activation (lactimation 83%, conjunctival injection 67%, rhinorrhea 56%, nasal congestion 43%); less frequently, signs of sympathetic dysfunction (ptosis 48%, miosis 7%) were also present. Two patients had attacks showing the typical localisation, severity and time course of CH attacks, but not accompanied by autonomic phenomena. A considerable part of the patients also observed symptoms that are usually ascribed to migraine (nausea 41%, vomiting 18%, photophobia 68%, phonophobia 58%). This may have been instrumental in the fact that, regardless of the characteristic clinical symptoms, the diagnosis of CH took 10 years on average. At the time of their examination 63% of patients were not using adequate abortive medications and 59% did not have an adequate prophylactic measure. Discussion - Cluster headache is characterised by attacks of devastating pain that warrant an early diagnosis and adequate treatment. Our study underlines that information about the diagnosis and therapy of CH should be emphasized on occasions of neurology specialty training and continuing medical education.]

[Patients suffering from chronic kidney disease reach the end-stage renal disease in ever growing numbers and this necessitates the start of their dialysis treatment. The alteration of bone and mineral metabolism together with the development of the consequent organ damages starts in early stages of the chronic kidney disease. The goal of our present trial was to survey the alterations or characteristics (laboratory results, concomitant diseases and treatment practice in Hungary) of the calcium (Ca) and phosphate (PO4) metabolisms [mineral-bone disorder occurring in chronic kidney disease (CKD-MBD) or formerly known as secunder hyperparathyreosis or renal ostedistrophy] in patients chronically treated with dialysis. We collected and analyzed data/results from 5334 chronically dialyzed patients. We categorized the patients into different groups according to the guidelines of CKD-MBD so basically by the level of serum calcium and parathormone (PTH) (se-Ca level is below or above 2.4 mmol/l; PHT level is below 65 pg/ml, between 65-150, 150-300, 300-500, 500-800 pg/ml or above 800 pg/ml) and then the characteristic variances were compared. The two most frequent primary causes of end-stage renal disease are hypertension (23%) and diabetes mellitus (22%). Serum calcium level was below the upper limit of the normal range (Ca <2.4 mmol/l) in the greatest proportion of our patients (n=4386), while the parathormone level was elevated (PTH >500 pg/ml) in large portion of patients (n=833). Likewise in a significant part of our patients (44.9%) the parathormone level was low (PTH <150 pg/ml). The concurrent pathological elevation of both the serum calcium and the parathormone levels was found in only a minority of the patients (n=150; 2.8%). All of the drugs influencing calcium-phosphate and parathormone levels were already accessible during the time of origin of the trial in Hungary, although the financial limitations significantly affected their prescription. This is one of the reasons why local treatment practice was not fully aligned with guidelines. On the other hand the application of native vitamin D had an especially low prevalence. To sum up, our results match the European practice on the whole, although we definitely need improvement in reaching the treatment targets and also the clinical treatment practice leading to it. We will prepare a proposal for further analysis and longterm extension of this trial.]
