Effects of mobile phone exposure on biochemical parameters of cord blood: A preliminary study.

The purpose of this study is to investigate foetal impact of radiofrequencies (RFs) emitted from mobile phones in postnatal cord blood. The study carried on 149 pregnant women divided into four groups such as nonusers of mobile phone (n: 37; control group), 2-15 min/d (n: 39; group 1), 15-60 min/d (n: 37; group 2) and participants using mobile phone for more than 60 min/d (n: 36; group 3). Cord blood of the infants was taken in all groups for biochemical analyses immediately after birth. The results of the study showed that the biggest foetal impact was observed in the third study group which was pregnant exposed RFRs (RF radiation) more than 1 h/d (1 hour per day). AST (aspartat aminotransferaz), ALT (alanine aminotransferase), LDH (lactate dehydrogenase), CK (creatine kinase), CK-MB (creatine kinase-miyocardial band), CRP (c-reactive protein), PCT (procalcitonin), TnT (troponin T), uric acid and lactate levels of third group were found higher than the other groups (p < 0.001). However, Mean platelet volume values of third group were found lower than the other groups (p < 0.001). Finally, this is the first human study which was performed on pregnant and infants because there is no previous work in this area. However, the results of this study revealed that long-term RFR exposure of pregnant may result in some biochemical changes in the infants. Therefore, our suggestion to pregnant is to avoid from RFR exposure emitted from mobile phones at least during pregnancy.

Diagnostic role of inflammatory markers in pediatric Brucella arthritis.

BACKGROUND: As a multisystem infectious disease, there is an inflammation, which causes increase in acute phase reactants in brucellosis. The mean platelet volume (MPV), platelet distribution width (PDW), red cell distribution width (RDW), neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) have been identified as markers of inflammation. The present study aimed to evaluate diagnostic values of these biomarkers in brucella arthritis (BA). METHODS: The study included 64 children with BA and 66 healthy control subjects. Demographic features, joint involvement, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and hematological variables were retrospectively recorded. In addition, results of synovial fluid and serum tube agglutination test for brucella together with treatment regimens were recorded. RESULTS: The mean age of the patients (53.1 % male) was 92.3 ± 41.2 months. The most commonly affected joint was ankle (53.1 %). Synovial fluid puncture-brucella agglutination test was positive in 22 (34.3 %) patients. Puncture culture was positive in 9 patients. Most of the patients (57.8 %) were treated with a combination of rifampicin plus sulfamethoxazole/trimethoprim and gentamicin. Significantly higher mean PDW, RDW, MPV, NLR and PLR values were found in children with BA compared to control subjects (p < 0.05). A positive correlation was found between MPV and NLR values (R (2) = 0.192, p < 0.001). CONCLUSION: Our findings indicated that NLR and PLR are indirect markers of inflammation that may be observed abnormally increased in children with brucella arthritis. Further longitudinal studies are needed to investigate this topic to establish the more clear associations.

Infantile digital fibromatosis (inclusion body fibromatosis) observed in a baby without finger involvement.

A 9-day-old male baby was hospitalized after his birth due to some swells under the skin. The hard consistency nodules observed under the skin all over the body of the patient were of different size, and presented lesions, among which the biggest was 1 × 1 cm. No lesions were observed on the fingers. By superficial ultrasonography, multiple isoechoic hypoechoic lesions were observed among the muscle plan. In thoracolumbar magnetic resonance imaging, multiple massif lesions retaining peripheral contrast (the biggest was 1.7 × 1.4 cm large) had been observed under the skin muscle plans, between the muscles of the extremities. The biopsy was positive for smooth muscle actin, but negative for desmin, S100, and CD34. These findings were diagnosed as infantile digital fibromatosis (IDF) (inclusion body fibromatosis). The case was presented with an objective to illustrate and remind that IDF can be observed in babies without finger involvement.

Retrospective clinical and laboratory evaluation of children with brucellosis.

BACKGROUND: Acute brucellosis is a zoonotic disease seen in childhood, with non-specific complaints and clinical findings that can affect the locomotor, gastrointestinal, genitourinary, hematologic, cardiovascular, respiratory, and central nervous systems. Particularly in endemic regions, it occurs as a result of consumption of unpasteurized milk and dairy products. In this study, clinical and laboratory findings of children with acute brucellosis are presented. METHODS: Data for 147 patients, aged 2-16 years, were evaluated retrospectively. RESULTS: The most frequent complaints and clinical findings were abdominal pain and fever. Other complaints and clinical findings included arthralgia, myalgia, loss of appetite, weakness, sweating, fatigue, headache, arthritis, hepatomegaly, and splenomegaly. Anemia was the most frequent hematological abnormality detected; other abnormalities included leukopenia, thrombocytopenia, and pancytopenia. CONCLUSION: Childhood brucellosis can cause non-specific complaints and particularly anemia and leukopenia as hematological abnormalities. It is easily treated, however, with appropriate antibiotics.

Clinical features and prognosis with Guillain-Barré syndrome.

BACKGROUND: Guillain-Barré syndrome (GBS) is an acute inflammatory polyneuropathy commonly characterized by rapidly progressive, symmetric weakness and areflexia. MATERIALS AND METHODS: We retrospectively assessed the clinical manifestations, results of electrodiagnostic tests, functional status and prognosis of 36 children diagnosed with GBS. RESULTS: Based on clinical and electrophysiological findings, the patients were classified as having acute inflammatory demyelinating polyradiculoneuropathy (AIDP) (n = 25), acute motor axonal neuropathy (AMAN) (n = 10) and acute motor-sensory axonal neuropathy (AMSAN) (n = 1). Twenty (55.5%) patients were males and 16 (44.5%) patients were females. The mean age of the 36 patients was 68.1 ± 45.01 months (range, 6-180 months). Five (13.8%) patients were younger than 2 years. The most common initial symptoms were limb weakness, which was documented in 34 (94.4%) patients. In our study, 18 patients (51.4%) showed albuminocytological dissociation (raised protein concentration without pleocytosis) on cerebrospinal fluid (CSF) examination. Three patients (8.3%) required mechanical ventilation therapy during hospitalization. Unfortunately, three (8.3%) patients died; one patient had AIDP and two patients had axonal involvement (one case was AMAN and another case was AMSAN). When we compared the cases of residual sequel/dead and cases of complete recovery for neural involvement type including AIDP, AMAN and AMSAN, we did not find a statistically significant difference between the groups (P > 0.05). CONCLUSION: Our findings showed that cases of GBS was not uncommon in children younger than 2 years of age, and CSF protein level might be found high in the first week of the disease in about one half of the patients, with a higher rate of morbidity and mortality in patients with axonal involvement than in those with AIDP.

Evaluation of children with nutritional rickets.

AIM: To evaluate the clinical findings, risk factors, therapy and outcome in 946 children with nutritional rickets. PATIENTS AND METHODS: This retrospective study included a review of medical records of patients with nutritional rickets between March 2004 and 2009. Patients who displayed both the biochemical inclusion criteria and the clinical signs/symptoms or radiological signs of rickets were included in the study. RESULTS: The present study included 946 patients aged between 4 months and 15 years. Distribution of the cases showed a density between December and May. The age at diagnosis, showed two peaks and most of the patients were in the age range 0-23 months and 12.0-15 years. In infants and young children, most of the patients had been admitted to the hospital due to infectious diseases. In older children, short stature and obesity were the most common complaints. CONCLUSION: Children aged between 0-23 months and 12.0-15 years were under most risk for nutritional rickets, especially in winter and spring and vitamin D should be given to them as supplementation dose.

The frequency of Hashimoto thyroiditis in children and the relationship between urinary iodine level and Hashimoto thyroiditis.

The aim of this study was to determine the frequency of thyroid autoimmunity in second grade primary school students and to examine the relationship between iodine and Hashimoto thyroiditis (HT). This was a cohort study performed with 1000 students. Urinary iodine levels, antithyroid peroxidase (anti-TPO) and antithyroglobulin (anti-Tg) antibodies were determined in all children. Children with anti-TPO or anti-Tg antibody positivity or with goiter were summoned for detailed examinations. In total, 36 cases (3.6%) were diagnosed as HT. The goiter frequency was found in 17.5% of the whole cohort. Additionally, iodine deficiency was found in 64.2% of all children. The median urinary iodine excretion was determined as 132 microg/L (range 382 microg/L) in the HT group, whereas it was 73 microg/L (range 390 microg/L) in children with goiter but without HT and 81 microg/L (range 394 microg/L) in normal children. The urinary iodine level of HT cases was significantly higher than the other two groups (p < 0.001). HT was also determined in 2% of patients with low urinary iodine levels, in 6.2% of patients with normal urinary iodine levels, and in 7.5% of patients with high urinary iodine levels. Our data demonstrates the close relationship between excessive iodine levels and autoimmunity.

New coagulant agent (ankaferd blood stopper) for open hemorrhages in hemophilia with inhibitor.

The treatment of hemophilia A patients with inhibitor could be very expensive. Ankaferd blood stopper (ABS) is a unique folkloric medicinal plant extract, which has historically been used in Turkish traditional medicine as a hemostatic agent. In this article, a 16-year-old boy was presented with uncontrolled bleeding, despite the treatment of factor VIII, rVIIa, factor VIII inhibitor bypass activity (FEIBA), cyclophosphamide, and prednisolone at circumcision site that resolved with ABS in minutes. Our patient with hemophilia A and inhibitor is the first clinical pediatric case.
