OBJECTIVE: in our study we measured the total serum lgE and specific lgE levels in the sera of 30 children with recurrent otitis media with effusion to investigare the incidance of atopy and whether allergy is a riskfactor jrýr the middle ear diseases.
STUDY DESIGN: This study was perftýrmed oýý 30 patients with OME (otiýis media wiýh ejjusion), wit/ý a median age of5.65±2.67 years. Our corýtrol group corýsisted of"20 children who had no otorhinolaryngological disorders. The median age of the control group was 5.5±2.39 years. Total lgE, specifýc lgE and eozinophilic cariorýic protein levels (ECP) were measured in the sera of study and control groups. Alt the parameters were measured in the lmmu lite 2000 analyzer, utilizing the chemilum inescent immunoassay method.
RESULTS: Total lgE /eve/s were.ftýund to he higher than normal in 25 out of 30 patients. Of these 25 patienrs who had high total lgE levels, 7 patients werefound to have also high specifýc lgE levels. Total lgE levels in the study group were significantly higher than those of the control group (p<0.0003 ).
CONCLUSION: Our results were in accordance with the majority of the studies in the literature. in 83% of the atopic children who have got the OME diagnosis, the serum total IgE levels were found high. But we found no correlation with the specifýc lgE levels. In atopic children the increased levels of the total lgE supports the idea that allergy increases the OME incidance.

OBJECTIVE: To investigate of brucella seropositivly in veterinary, veterinary students and veterinary paramedical persons.
MATERIAL AND METHOD: We studied brucella microscopes/ide agglutination, brucella tuhe agglutioýation and Coombs from 123 serum specimerns.
RESULTS: Worked group seropositivily was higher than control group.

OBJECTIVE: in this study, percutaneous firýe needle biopsies which were done in Þiþli Etfal Hospital Pediaýric clinics between October 1997 and June 1999 were examined for the adeguancy of materials, complications and effect on diagnosis.
STUDY DESIGN: 47 patients who were hospitalized in Þiþli Etfal Hospital pediatrics clinics between August 1997 and June 1999 were included into the study, Percutoneous liver fine needle biopsy was done with Menghini 1.6 needle Sedation was dýme with midazolam to patients before biopsy.
RESULTS: The age range of the patients included to the study differed, between 20 day and 14 years 6 of the patients were newborns, 8 were injant 33 (!f' then were 2 years and older. Ali of the newborns were invastigated for hepatomegaly and prolanged jundice. Except ýme newborn all of then got the diagnosis of neonatal hepatitis. in 3 infants, metabolik disease was found who aggured for hepotomegaly. 25 of the patients who were 2 years and other that were aggured for hepatomegaly and suspicion of chronic viral hepatitis; Chonic active hepatitis as diagnosed.
CONCLUSION: Percutaneous liver jýne needle biopsy is a efficient and safe technic to the differetiente etiolojies of liver disease in childhood.
