Prevalence of IgE mediated cow's milk and egg allergy in children under 2 years of age in Sanliurfa, Turkey: the city that isn't almost allergic to cow's milk.

AIM: Food allergy is a common problem in children and adults. The aim of this study was to determine the frequency of cow's milk and egg allergy based on skin prick test and oral food challenge results METHODS: We recruited 614 children aged 1 month-2 years in from different areas of Sanliurfa. An interview was conducted with each parents and family demographic, and prenatal-antenatal-postnatal information was recorded, then skin prick test was applied to the children for egg white, egg yolk and cow's milk. Cases that are required, sIgE levels for cow's milk, egg white and egg yolk were measured and food challenge tests were applied. RESULTS: Cow's milk and egg allergy was determined in 1 case (0.16%) and 8 cases (1.30%) respectively from the results of the tests applied. Six cases (0.97%) were accepted as sensitive to egg white and egg yolk. Within the factors which were questioned, (only the egg allergy evaluation was made without the cow's milk allergy case) of those with parental consanguinity was determined at a statistically significantly high level (OR=5.8, 95% CI: 1.2-27.2, P=0.01). CONCLUSION: The prevalence of cow's milk allergy in Sanliurfa is the lowest reported prevalence rate to date in children under 2 years of age. When infants develop a food allergy, this takes the form of egg allergy. Within the several factors evaluated to explain this situation, a significant relationship was determined only with parental consanguinity. However, as reported above, to date there is no genetic or epidemiological study to explain this situation.

The reliability and validity of Turkish version of Childhood Asthma Control Test.

INTRODUCTION: The reliability and validity of Turkish version of Childhood Asthma Control Test (C-ACT). PURPOSE: The management of asthma is an important as well as difficult issue of physician's daily practice particularly in busy clinical settings. C-ACT was created to identify asthma control levels in children aged 4-11 years. Our aim was to evaluate the reliability, validity and responsiveness of C-ACT in a Turkish sample of children with asthma. METHOD: In this multicenter study, 368 children were enrolled. C-ACT was completed every month by parents and patients who were evaluated in 3 visits within 2 month intervals. At each visit, physicians interpret the control level and decided for the treatment step as established in GINA guidelines. RESULTS: The internal consistency reliability of the Turkish version of C-ACT (C-ACT1 to C-ACT5) was found to be 0.82, 0.83, 0.82, 0.82 and 0.80, respectively (reliability statistics, Cronbach's alpha). Test-retest reliability was 0.71. There was significant correlation between C-ACT and physician's assessment of asthma control at visit 1 (r = 0.65, P < 0.001). CONCLUSIONS: Turkish version of C-ACT is an accurate and reliable tool to evaluate asthma control in children aged 4-11 years. Its widespread use may facilitate appropriate assessment of asthma control and may lead to decrease the number of uncontrolled patients.

Dandy-Walker syndrome together with occipital encephalocele.

Dandy-Walker malformation is an anomaly characterized by dysgenesis of the foramina of Magendie and Lushka in the upper 4(th) ventricle, hypoplasia of the cerebellar vermis and agenesis of the corpus callosum. Encephalocele is diagnosed from the calvarium defect, cerebrospinal fluid (CSF) and herniation of the meninges. It is the rarest neural tube defect. A 7 x 9 cm encephalocele was found on physical examination of a 6-day old baby boy patient. From cranial magnetic resonance, it was seen that the posterior fossa was enlarged with cysts and there was agenesis of the vermis. A connection was established between the ventricle and the development of cysts on the posterior fossa. These findings were evaluated as significant from the aspect of Dandy-Walker malformation. The extension of the bone defect in the left occipital area towards the posterior, and the cranio-caudal diameter reaching 9 cm was seen to be in accordance with encephalocele. It is rare for Dandy-Walker syndrome to occur together with occipital encephalocele. The authors present a case of Dandy-Walker syndrome together with occipital encephalocele.

''Air-bubble'' signs in the CT diagnosis of perforated pulmonary hydatid cyst: three case reports.

Computed tomography is an important imaging modality in the evaluation of hydatid cyst. However, diagnosis of perforated hydatid cyst is very difficult and for this reason some radiological findings have been defined. An important finding is the ''air bubble'' sign. As a consequence of cyst rupture, secondary bacterial infections like bronchopneumonia or lung abscess may develop which complicate the clinical picture further. In the literature, the ''air bubble'' sign which is a relatively newly discovered radiological sign is reported to be very sensitive in establishing diagnosis. For this reason, in suspected cases of hydatid cyst, the air bubble sign may aid physicians in establishing diagnosis.

Urticaria and angioneurotic edema due to the temporary henna tattoo.

Temporary henna tattoo, which has become popular among young people, is obtained from the mixture of the plants Lawsonia alba or Lawsonia inermis and paraphenylenediamine (PPD). In forming reactions frequent development of anti-PPD substance is noticed. A 13-year old boy who started itching, erythema, enduration on the application area, increasingly urticarial rash, conjunctivitis and swelling of the lips 48 h after being applied the temporary henna tattoo was hospitalized. He had a local reaction to henna tattoo when he was 5-year old. He was treated with parenteral corticosteroids and oral antihistaminic drugs. Skin reactions persisted for 18 days. The patient showed no early reaction to henna 10% and PPD 1% concentration in saline solution but did late reaction (after 48 h) to PPD in diameter of 12x13 mm in prick test in 3 weeks after the reaction. A case who developed angioneurotic edema and urticaria to temporary henna tattoo noticed that the henna tattoo is not an innocent application and young people need to be informed on this subject.

Parasite density and serum cytokine levels in Plasmodium vivax malaria in Turkey.

We aimed to investigate the relationship between quantitative Plasmodium vivax parasitaemia and serum cytokine levels in a highly endemic region of Turkey, where such a relation has not been investigated before. Active screening was done in a total of 1316 people residing in 33 villages of Sanliurfa province, Turkey. The study population consisted of 79 consecutive patients with P. vivax malaria, and a control group included 89 healthy subjects. Thick blood smears were examined for malaria parasite and parasite count. Serum samples were analysed for IL-1beta, IL-2, IL-4, IL-6, IL-8, IL-10 and IL-12 by the ELISA method. Compared to controls, levels of pro-inflammatory cytokines, i.e. IL-1beta, IL-6 and IL-12, were significantly higher in patients with parasitaemia. There was a significant positive correlation between serum IL-10 and IL-12 levels and the parasite burden (r = 0.264, P = 0.024 and r = 0.264, P = 0.024, respectively). Serum IL-8 levels showed a significant negative correlation with parasite burden (r =-0.356, P = 0.002). There was a positive correlation between IL-8 levels and age, while the opposite was observed for IL-12. High fever was correlated with IL-6 and IL-10 levels. Compared to controls, patients with a parasite count greater than 5000/microL had a significantly higher IL-1beta and IL-10 levels (P < 0.05), while the difference was not significant for patients with a parasite count less than 1000/microL. Thus, we can conclude that pro-inflammatory response against P. vivax gains more importance during periods of increased parasite burden.

Ultrasonographic findings in ceftriaxone: associated biliary sludge and pseudolithiasis in children.

PURPOSE: To prospectively evaluate the incidence of biliary sludge and pseudolithiasis in children treated with ceftriaxone. MATERIAL AND METHODS: Thirty-three children (14 girls, 19 boys) treated with ceftriaxone for prophylaxis (n=13) or for an infection (n=20) were included in this study. The incidences of biliary sludge and pseudolithiasis were investigated using ultrasonography. The ultrasonographic evaluations were performed prior to and on the 4th-5th days and on the 8th-10th days of treatment. The patients who had biliary sludge or pseudolithiasis were followed up with ultrasonographic evaluation periodically until these pathological phenomena disappeared. RESULTS: Ceftriaxone was administrated intravenously at a dosage of 100 mg kg(-1) day(-1). Serial gallbladder sonograms were performed before treatment and on the 4th-5th and 8th-10th days of therapy. Nineteen children developed pseudolithiasis and sludge in the gallbladder, and all were asymptomatic. No significant differences were found between the patients with normal versus abnormal sonographic findings in regard to gender, age, duration of the therapy, oral restriction except the presence of surgery (P< 0.005). CONCLUSION: The combination of oral restriction and surgical procedures may be a causal factor in ceftriaxone-associated biliary pseudolithiasis. It is emphasized that when gallstone and/or sludge are detected in the gallbladder in children by ultrasonographic examination, the administration of ceftriaxone must be sought beyond other causative factors.

Relationship among manganese, arginase, and nitric oxide in childhood asthma.

It has been demonstrated that the lowest intakes of manganese (Mn) were associated with more than a fivefold increased risk of bronchial reactivity. It was also known that nitric oxide (NO) production was found to be significantly higher in asthmatics. There is a reciprocal pathway between arginase and nitric oxide synthase (NOS) for NO production, and Mn is required for arginase activity and stability. We investigated plasma NO, arginase, and its cofactor Mn levels to evaluate this reciprocal pathway in patients with childhood asthma. Arginase activities and Mn and NO levels were measured in plasma from 31 patients with childhood asthma and 22 healthy control subjects. Plasma arginase activities and Mn concentrations were found to be significantly lower and NO levels were significantly higher in patients with childhood asthma as compared to the control subjects. There was a significantly positive correlation between plasma Mn and arginase and negative correlations between arginase and NO values and Mn and NO values in patients with childhood asthma. These data indicate that the lower concentration of Mn could cause lower arginase activity and this could also upregulate NO production by increasing l-arginine content in patients with childhood asthma.
