Sensitization to Food Allergens in Mureș Region Atopic Children by in vitro Specific Ig E Assay

Background: Food allergies are adverse immune reactions to food proteins that affect up to 6% of children. There are little data regarding the frequency of different foods that cause hypersensitivity in Romania.
Objective: To determine the frequency of sensitization to food allergens in children seen in pediatric immuno-allergy services from Tîrgu Mureș, Romania.
Patients and methods: Specific Ig E serum levels to allergens were measured in 113 children in pediatric allergy services and in 36 control children with matching ages. RAST equal or higher than class 1 was considered as positive.
Results: Frequency of positive reaction was significantly higher among atopics (92/113; 81.4%) when compared to controls (8/36; 25.8%). There were little differences according to gender. The frequency of positive reaction to all evaluated allergens was higher among atopics when compared to controls. In relation to food allergens we observed: cow’s milk = 46.9% x 2.8% (p <0.05), egg = 11.5% x 0.0% (p <0.05). With respect to age, food allergen sensitization predominates in young children.
Conclusions: Food allergens were responsible for a significant proportion of sensitization, mainly in infants.

Study on the Activity of the Cardiac Arrest Teams from the Emergency Department of the Clinical Emergency County Hospital from Tîrgu Mureș, Romania, in 2009

Objective: To evaluate the activity of the Cardiac Arrest Team (CAT) from the Emergency Department, called to perform resuscitation for patients admitted in different departments of the Clinical County Hospital.
Methods: We conducted a prospective study between 01/01–12/31/2009. We included all the patients we performed CPR on, regardless of indication.
Results: We had a total of 110 cases, representing 0.28% of the 39,074 patients assisted by the department in 2009. We noticed an increased incidence of calls in internal medicine and surgery departments, with 50% and 17% of the cases respectively. The most frequent diagnosis was cardiac arrest for respiratory failure and malignant tumors, each representing 17%, even though malignancy does not have an indication for resuscitation. There was no causal relationship between the outcome of resuscitation and age groups (p = 0.552), type of wards (p = 0.36), or the Basic Life Support (BLS) performed by the staff, before the CAT arrived (p = 0.76). Medical staff from wards started BLS in 40.1% of cases, in 32% of these cases only chest compressions were performed, without ventilation.The proportion of resuscitated versus deceased cases is 49.1% to 50.9%, so immediate results are good, unfortunately the late outcome is bad, 52 cases out of the 54 died later in ICU, 2 patients being discharged in good condition.
Conclusions: CAT should be called according to Do Not resuscitate criteria. Medical staff from the wards should be trained to start CPR and have basic equipment. The early outcome is comparable with the international data, the poor late results binds to resuscitation without indication.

The Communication Systems Between the Rescue Teams in Case of Disaster. Evaluation of the Awareness of the Health Professionals and the General Public

Introduction: The integration of communications and the unified coordination in interventions are essential to reduce the risk of the emergency medical personnel. The purpose of this study is to assess the level of awareness of the population and health professionals regarding the medical emergency and disaster response system as well as the importance of an integrated communication system and coordination of the involved teams.
Material and method: For the purpose of this study two questionnaires were used: initial evaluation and a rewiew. The first questionnaire was applied on a sample of 138 persons, medical personnel from several medical centers in the country (Tîrgu Mureș, Timișoara, Cluj Napoca, București). The second questionnaire was applied on a sample of 120 persons from the general public. The data obtained were statistically analysed using several methods: Friedman test, Kendall tau test, Wilcoxon test, GraphPad Prism 5 and SPSS Statistics 17.0.
Results: The statistically significant difference (p <0.05) among the mean scores obtained by analysing the answers to the first two questions contained in the first questionnaire, shows a poor knowledge related to the emergency response system as well as to the communication systems used in disasters, among doctors and nurses. The answers to the questions contained in the questionnaire applied to the general population revealed a dissatisfaction as well as a lack of knowledge about the existing emergency medical system. The presentation of the Mobile Command Centre led to a better understanding of the emergency response system as well as of the advantages of an integrated communication system in disasters, among the medical personnel and general public.
Conclusions: This study draws attention on the lack of information about the emergency medical system, disaster response and especially on the integration of the communication system between the teams involved in this kind of emergencies. The informative training performed during the second part of the study led to an improvement of the perception regarding the indispensability of an intergated communication system, among the medical personnel and the general public.

The Detection of Premalignant Gastric Lesions by Conventional and Magnifying Endoscopy

Introduction: Early diagnosis of gastric neoplasia involves both the detection and surveillance of patients with premalignant gastric lesions. Magnifying endoscopy allows the analysis of the fine mucosal structure and microvascular architecture.
Material and methods: The aim of our study is to identify specific patterns associated with premalignant gastric lesions by magnifying endoscopy in conjunction with chromoscopy. We performed conventional upper endoscopies and we selected a number of patients for chromodiagnostic and magnification. We classified the endoscopic patterns in normal and abnormal (modified) patterns. Target biopsies were obtained from magnified areas and we analyzed the correspondence with the histological findings.
Results: We identified specific pit patterns for normal gastric mucosa and for inflamed mucosa. A tubular pattern was associated with the detection of intestinal metaplasia. An irregular pattern and abnormal microvessels were endoscopic findings associated with the detection of high-grade dysplasia. An irregular form of collecting venules was detected in areas with atrophic gastritis.
Conclusions: An initial selection of patients based on conventional endoscopic findings is mandatory. Gastric mucosal changes identified by magnifying endoscopy raise the number of detected premalignant lesions by targeted biopsies. Our work emphasizes the current challenges related to the use of these endoscopic methods.

Dissection of the Cervico-Cerebral Arteries – Ultrasonographic Characteristics

Background: Dissection of the cervical and cerebral arteries represents the leading cause of non-atherosclerotic stroke in young adults. The diagnosis can be difficult as the presentation may be variable. The ultrasound (US) examination is the first diagnostic procedure, because is non invasive and informative.
The aim of this study was to analyse the ultrasonographical characteristics of the cervico-cerebral artery dissections (CCAD).
Patients and methods: We analyzed 8 consecutive cases of CCAD examined in the Ultrasound Laboratory of Neurology Clinic I from Tîrgu Mureş, Romania over a 3-year period. The mean age of the patients was 39.5±12.1 (min. 24, max. 60), the male/female ratio: 1.
Results: In 5 cases the diagnosis was established based on the ultrasound findings, in 2 cases was confirmed by angiography and in one case by MRI angiography. In 3 cases the CCAD occurred at the level of the proximal internal carotid artery (ICA), in 2 cases at distal ICA, in one case the common carotid artery, in 1-1 cases the proximal and distal part of the vertebral arteries. The most frequent ultrasound finding suggestive for CCAD was the hypoechogenic wall haematoma (3 cases). The hyperechogenic intimal flap occurred in 2 cases, the classical double lumen only in one case. In three cases the ultrasound examination revealed only indirect signs of occlusion. In one case the ultrasound findings were not suggestive for ICA dissection, the diagnosis was confirmed based on the angiography findings.
Conclusions: Color duplex ultrasound examination is an important diagnostic method in the diagnosis of CCAD with good sensitivity and specificity. The most frequent ultrasound finding in CCAD is the hypoechogenic mural haematoma. In patients with suspected CAD and negative US, repeated US examinations and further diagnostic imaging, as angiography, MRI, MRI angiography must be performed.

Specialized Software Engineering in Clinical Trials. GANfort Study

Objective: We aim to develop and implement a personalized software to accomplish data quality management in real time, reducing the chance of error in data collection and a “real time biostatistics” software linked to a collector datasheet.
Material and methods: We used C++ for programming, R for statistics and JavaScript (AJAX) for the interface. This application was deve-loped for phase 3 GANfort study. This is a multicentric study. The results presented are simulated.
Results: The application presented below has a datasheet collection view with three tabs and a general presentation of the study and patient. The first tab collects data from the first visit (study inclusion and initiating the treatment), the second tab is for surveillance visit and the third tab generates real time statistic parameters.
Discussions: Using this type of software many methodological problems concerning data management can be avoided. “Missing data” and “outliers” or writing and typing errors become non-existent; typing constraints issued by datasheets and real time biostatistics eliminate them. The data can be introduced in the same time in different places and the matching data is performed simultaneously.
Conclusions: The time consuming data quality management is automatically solved using the software we proposed. Statistical parameters are calculated in real time. The end of data collection coincides with a final report of the study.

A Randomized Trial of Prophylactic Administration of Phenylephrine vs. Ephedrine for Treatment of Hypotension during Combined Spinal-epidural Anesthesia for Cesarean Delivery

Ephedrine and phenylephrine are useful vasopressors for managing hypotension during caesarean delivery. Fetal arterial cord blood pH and fetal acidosis may be related to the choice of vasopressor. The present study was therefore designed to compare arterial cord blood pH and fetal acidosis rates by vasopressor treatment, while maintaining maternal mean arterial pressure (MAP) near baseline values. Fifty one ASA I-II parturients undergoing cesarean delivery (CD) under combined spinal-epidural anesthesia (CSEA) were randomly assigned to prophylactic infusion (20 mL.hr-1) of phenylephrine (100 µg.ml-1, n=25) or ephedrine (3 mg.ml-1, n=26) prior to CSEA. The infusion, was titrated to maintain mean arterial pressure (MAP) near baseline values. The primary outcome was arterial cord blood pH. Fetal acidosis was defined as pH <7.2; maternal hypotension as MAP <70 mmHg; and maternal bradycardia as heart rate <50 bpm. Arterial cord blood pH was 7.32±0.06 in the ephedrine group vs. 7.32±0.05 in the phenylephrine group, p=0.9. Fetal acidosis occurred in one case (4%) in each study group with similar one- and five-minute Apgar scores (all >7). Hypotension episodes were more frequent in patients given ephedrine (10 patients; 38%) than phenylephrine (three patients; 12%), (p=0.03). We conclude that prophylactic ephedrine as compared to phenylephrine administration was associated with a relatively high incidence of hypotension but with similar cord blood pH.

No Editorial for a Blurred Window

A parochial journal like ours sticks to its values. Strives to be acknowledged as a reliable means of communication. As an opportunity to the members of our university to publish their research. And what are exactly our values?
Fairness as to the intent of the research, good faith, correctness and transparency, curiosity, respect for the subjects and equally for the research team members. All post-Hippocratic principles. But just as afterload includes preload, we know that all the ancient Hippocratic principles are in and observed, and followed.
These lines are intended for our readers and authors to let them know that they are welcome to submit their articles, provided they follow the rules. Medical literature is made to be read, articles to be analyzed, sometimes even quoted. Authors are more or less driven by genuine appetite for research. No matter the driving force, a good outcome is to be expected, utilitarians as we often tend to be.
One of my PhD students confessed recently that the more she was involved, the more she became interested in research. Ideas came as she worked and analyzed results. [More]
