Does mobile phone use of women during pregnancy cause hearing problems in infants? Preliminary observation

Objective Some studies have claimed that long-term conversation with mobile phones can cause hearing loss. However, it has not been investigated whether exposure to mobile phones during pregnancy affects the hearing of babies in the womb. Therefore, the aim of this human study was to investigate the effects of intrauterine radiofrequency radiation (RFR) exposure emitted from mobile phones on the hearing of newborns. Methods The study population comprised 149 newborns. Pregnant women in this study were divided into 4 groups according to RFR exposure duration, such as non-exposure to RFR, exposure to RFR for 2–15 min/day, exposure to RFR for 15–60 min/day, and exposure to RFR for more than 60 min/day. The results of the hearing screening analyses of the newborns, which were performed using transiently evoked otoacoustic emission and auto auditory brainstem response, were investigated retrospectively. Results The results of this study indicated that 900 and 1800 MHz RFR exposure during pregnancy did not cause hearing loss in newborns. Conclusion In conclusion, we observed that the hearing sensitivity and peripheral sound perception of newborns were not affected by RFR exposure emitted from mobile phones during the intrauterine period. Further studies should be performed to illuminate the subject

Mycoplasma pneumoniae meningoencephalitis: a case report

Nervous system is the most affected area in mycoplasma pneumoniae infections with exception of respiratory system. It is an important agent of childhood acute encephalitis and respiratory system infections in school-age children and young adults. Routine clinical and laboratory findings to identify spesific diagnosis is limited. Twelve-year-old female patient was admitted with fever, fatigue, sore throat, slipping the right eye, withdrawal of the mouth from the right and right hemiclonic seizures. Test of anti-Mycoplasma pneumoniae (M. pneumoniae) IgM was positive and IgG antibodies were found to be 4-fold increase in the sera of follow-up. This article was presented with the aim of remembering M. pneumoniae to be an differential diagnosis in children with acute encephalitis

Biotidinase deficiency accompanied by diffuse demyelination and cerebral atrophy

Biotinidase deficiency is an inherited disorder which has autosomal recessive pattern; it occurs in approximately 1 in 60,000 live births. Usually it manifests seborrheic dermatitis, alopecia, ataxia, convulsions, hypotonia, developmental delay, hearing loss, chronic lactic acidosis and immune deficiency. Its diagnosis is made by the measurement of serum biotinidase enzyme activity and determination of the enzyme. Herein presented that a two and half-month-old boy with biotinidase enzyme deficiency which had cerebral atrophy without any skin signs. In the patients presented with refractory convulsions with unexplainable etiology without any skin lesions, as in our patient, biotinidase enzyme deficiency should be considered and the treatment should be established in early period to prevent many complications that may develop

Yaygın demiyelizasyon ve serebral atrofi ile seyreden biotinidaz eksikliği

Biotinidaz eksikliği yaklaşık olarak 60.000 canlı doğumda bir görülen otozomal resesif geçişli herediter bir hastalıktır. Bu hastalıkta genellikle seboreik dermatit, alopesi, ataksi, konvülsiyon, hipotoni, gelişme geriliği, işitme kaybı, kronik laktik asidoz ve immün yetmezlik görülür. Serumda enzim düzeyi ve aktivitesi ölçülerek tanı konulur. Burada herhangi bir cilt bulgusu olmaksızın serebral atrofi ile başvuran 2,5 aylık erkek biotinidaz olgusu sunulmuştur. Hastamızda olduğu gibi etiyolojisi belli olmayan dirençli kon- vülsiyonlar ile başvuran ve herhangi bir cilt bulgusu olmayan hastalarda biotinidaz eksikliği göz önünde bulundurulmalıdır. Ayrıca gelişebilecek komplikasyonların önlenmesi için erken dönemde tedavi uygulanmalıdır.Biotinidase deficiency is an inherited disorder which has autosomal recessive pattern; it occurs in approximately 1 in 60,000 live births.

Retrospective clinical and laboratory evaluation of children with brucellosis

WOS: 000302935400009PubMed: 22212683Background: 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

Acute leukemia case presented with hypercalcemia

An 8-year-old girl patient referred to our emergency clinic with articular pain, stomachache and fever complaints. Past history revealed that she was suffering from pain in both knees and ankle joints for 8 days. The joint temperature increased and swelling did not accompany articular pain. Family history was unremarkable. In the physical examination, there was sensitivity in the knees, elbows and ankles during movement. The patient had normal complete blood cell count, and no blast or atypical cells were observed in peripheral smear. Serum electrolytes, liver and kidney function tests were normal except for hypercalcemia. The 25 (OH) vitamin D and 1-25 (OH)2 vitamin D levels were within normal range. In bone marrow aspiration, infiltration of cells with lymphoblastic and homogenous cellular features was observed. With positivity of cCD79, CD19, CD45, the case was considered as preB cell leukemia. Body bone scintigraphy performed for bone metastasis was normal. After the chemotherapy, hydration and furosemid treatment, the calcium level returned to normal. This case emphasized on the fact that, children with hypercalcemia should undergo a detailed examination for malignancies even though no blast or atypical lymphocyte are observed in their peripheral blood smear before steroid treatment is applied and if necessary, bone marrow aspiration should be taken into account.</span

A case of immune thrombocytopenic purpura presenting with intracranial hemorrhage

Immune thrombocytopenic purpura is an acute, generally considered a self-limiting benign disorder with a 60%-80% change of spontaneous recovery occurring usually within a few months after onset. Intracranial hemorrhage is a rare but life-threatening complication of childhood immune thrombocytopenic purpura. We report a 4-year-old girl who admitted with headache, vomiting, bleeding from noise and bruises on the extremities. Her neurological examination was normal. Based on laboratory finding she was diagnosed immune thrombocytopenic purpura and intracranial hemorrhage. We suggest that cranial imaging should be perform in patients with immune thrombocytopenic purpura admitted with bleeding symptoms, vomiting and headache even if they had no abnormal neurological signs

Determination of underlying causes in asymptomatic, earlystage renal diseases by dipstick test

PubMed ID: 23348162Aim To prevent possible chronic kidney diseases in healthy school- age children by screening for hematuria and proteinuria using a urine strip. Methods The incidence of hematuria and proteinuria was determined in 1848 healthy school-age children aged 7 to 14 years by urine screening in the eastern region of Turkey in 2008. Cases with persistent hematuria and/or proteinuria were referred to a pediatric nephrologist, and further examinations were carried out. Results Isolated hematuria, isolated proteinuria, and combined hematuria-proteinuria were found in 92 (4.9%), 16 (0.8%) and 10 (0.5%) patients, respectively. In addition, 11.9% (11/92) of cases of isolated hematuria and 40% (4/10) of cases of combined hematuria- proteinuria were observed to have persisted. Persistent hematuria and persistent hematuria-proteinuria were found in 11 (0.5%) and 4 (0.2%) patients, respectively. In these cases, underlying causes were found: renal stone disease, hypercalciuria, urinary tract infection, vesicoureteral relux, atrophic kidney, and IgA nephropathy. Conclusion According to this study, cases with persistent hematuria should be examined especially in terms of renal stones, hypercalciuria, and urinary tract infection
