The rate of reported IgE-mediated FA was significantly higher than clinically confirmed FA by means of DBPCFC (odds ratio, 7.46; 95% CI, 4.67-12.01; P<0.0001). The order of allergenic foods was different and somewhat unique to the eastern Black Sea region of Turkey when compared with western countries.
Anaphylaxis was seen significantly more in boys. Most of the reactions occurred at home. Foods were the most frequent cause. Epinephrine, the first-line treatment of anaphylaxis, was administered in only a third of the children.
Background-The hyper IgE syndrome (HIES) is characterized by abscesses, eczema, recurrent infections, skeletal and connective tissue abnormalities, elevated serum IgE and diminished inflammatory responses. It exists as autosomal dominant (AD) and recessive (AR) forms that manifest common and distinguishing clinical features. A majority of those with AD-HIES suffers from heterozygous mutations in Signal Transducer and Activator of Transcription 3 (STAT3) and impaired Th17 differentiation.
The implementation of the Expanded Program of Immunization (EPI) in 1989 has dramatic impact on hepatitis B virus (HBV) infection in school children in Malaysia. A cross-sectional seroprevalence study of HBV infection in 190,077 school children aged 7-12 years from 1997 to 2003 showed a steady decline of HBV surface antigen (HBsAg) prevalence rate from 2.5% for children born in 1985 to 0.4% among school children born in 1996. The overall prevalence of HBsAg was 0.6%, 0.7% in males and 0.6% in females. Over 92.7% of school children had been vaccinated with HBV vaccine, in which 93.7% were vaccinated under the EPI and 6.3% on voluntary basis. The school children vaccinated under EPI had a 0.4% HBsAg carrier rate, which was significantly lower than school children vaccinated on a voluntary basis (HBsAg carrier rate 1.3%) and non-vaccinated school children (HBsAg carrier rate 2.7%), suggesting that HBV vaccination of infants was the most effective measure in preventing vertical transmission of HBV in the hyperendemic region.
Streptococcus pneumoniae is the most common etiological cause of complicated pneumonia, including empyema. In this study, we investigated the serotypes of S. pneumoniae that cause empyema in children. One hundred fifty-six children who were diagnosed with pneumonia complicated with empyema in 13 hospitals in seven geographic regions of Turkey between 2010 and 2012 were included in this study. Pleural fluid samples were collected by thoracentesis and tested for 14 serotypes/serogroups using a Bio-Plex multiplex antigen detection assay. The serotypes of S. pneumoniae were specified in 33 of 156 samples. The mean age ؎ the standard deviation of the 33 patients was 6.17 ؎ 3.54 years (range, 0.6 to 15 years). All of the children were unvaccinated according to the vaccination reports. Eighteen of the children were male, and 15 were female. The serotypes of the non-7-valent pneumococcal conjugated vaccine (non-PCV-7), serotype 1, serotype 5, and serotype 3, were detected in eight (14.5%), seven (12.7%), and five (9.1%) of the samples, respectively. Serotypes 1 and 5 were codetected in two samples. The remaining non-PCV-7 serotypes were 8 (n ؍ 3), 18 (n ؍ 1), 19A (n ؍ 1), and 7F/A (n ؍ 1). PCV-7 serotypes 6B, 9V, 14, 19F, and 23F were detected in nine (16.3%) of the samples. The potential serotype coverages of PCV-7, PCV-10, and PCV-13 were 16.3%, 45.4%, and 60%, respectively. Pediatric parapneumonic empyema continues to be an important health problem despite the introduction of conjugated pneumococcal vaccines. Active surveillance studies are needed to monitor the change in S. pneumoniae serotypes that cause empyema in order to have a better selection of pneumococcal vaccines.
The presence of a family history of beef allergy, beef specific IgE value, and skin test result positivity are independently associated with positive DBPCFC results, and combined evaluation of these three parameters increased the positive predictive power of the tests.
In this study we presented 92 cases with regional lymphadenitis (over 1 cm in diameter) which was caused by BCG vaccination generally performed a few days after birth. The patients were divided into four therapy groups. In group I, the lymphadenitis in 26 cases was excised totally by a surgical operation and they improved in a median period of four weeks (average: 4.4). No therapy was applied in 33 patients constituting group II and their periods of improvement were 28 weeks (average: 29.1). Sixteen cases in group III were given isoniazid (INH) 10 mg/kg for six months in addition to total surgical excision and their healing period was 4.5 weeks (average: 4). Seventeen cases in group IV were administered only INH for six months and the median improvement period was found to be 27 weeks (average: 28.2). The statistical differences in terms of the improvement periods between groups I and III, and groups II and IV were found to be insignificant (p greater than 0.05) but these differences were significant between groups I and II, groups I and IV, groups II and III, and groups III and IV (p less than 0.05). These results show that spontaneous healing is possible. Total excision is the best therapy for BCG lymphadenitis in suppurative forms and INH has no effect in shortening the therapy period.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
