Background: Food allergy is a public health issue that has a significant impact on the lives of families. Parental self-efficacy/confidence is important in managing food allergies. The aim of this study is to validate the "Food Allergy Self-Efficacy Scale for Parents" (FASE-P) and assess parental self-efficacy in managing their child's food allergy., Methods: Turkish version of the FASE-P (T-FASE-P) was administered to 347 parents of children aged 0-18 who had been followed for at least one month due to food allergy at the Pediatric Allergy Clinic of Prof. Dr. Cemil Taşcıoğlu City Hospital between September 1 and December 31, 2023, through face-to-face interviews and online surveys for parents of children with food allergies from the general population. Content validity, exploratory factor analysis (EFA), and confirmatory factor analysis (CFA) were conducted to evaluate the validity of the scale. General Self-Efficacy Scale (GSES) was used for concurrent criterion validity. Internal consistency analysis, test-retest application, and item analysis were conducted to assess its reliability., Results: T-FASE-P scale initially contained 21 items, and the Cronbach's alpha coefficient (α) calculated in this form was found to be 0.89. Later, when 4 items were excluded, the 17-item version of the scale was calculated as α=0.90. The intra-class correlation coefficient between the test and re-test was found to be 0.972. The content validity index value of the scale was calculated as 0.99, indicating that the content validity was at a sufficient level. In the EFA, it was determined that the scale formed a three-factor structural model and that this model explained 60.82% of the total variance. As a result of the CFA, the fit indices were calculated as χ2/df=2.341, GFI=0.919, TLI=0.950, indicating a good level of fit. Based on the analysis results, T-FASE-P consists of 17 items and three subscales., Conclusion: T-FASE-P scale is a valid and reliable measurement tool that can be used to determine the food allergy self-efficacy of Turkish parents., Competing Interests: The authors declare that there is no conflict of interest.

The infection of the orbita and ocular tissues can result in severe local and systemic complications. We aimed to determine the predisposing factors for preseptal and orbital cellulitis, the clinical and routine laboratory differences between orbital and preseptal cellulitis, and the change in the spectrum of the pathogens and the antibiotics used in the last 10 years. One hundred thirty-nine patients, hospitalized in Hacettepe University Faculty of Medicine Children's Hospital between 1 January 1990 and 31 December 2003 with diagnosis ofperiorbital or orbital cellulitis, were reviewed retrospectively. Ten of the patients (7%) had orbital and 129 (93%) had preseptal cellulitis. The male/female ratio was 1.7:1. The average age (mean+/-standard deviation) was 5.7+/-4 years. The seasonal distribution was most marked in spring and fall periods. When compared with preseptal cellulitis, the mean blood cell count, erythrocyte sedimentation rate and C-reactive protein levels were significantly higher in patients with orbital cellulitis. Staphylococcus aureus was isolated in 13 (41.9% of total microbiologically confirmed cases), coagulase-negative staphylococcus in 8 (25.8%), and H. influenza type b in 2 patients (6%). Thirty out of 77 clinical sample cultures (39%) were positive. In clinical studies, etiological agents of orbital and preseptal cellulitis could be identified in only 20-30% of cases, so in clinical practice treatment is usually empiric. We observed that sulbactam-ampicillin was a safe and effective choice of treatment in orbital and preseptal cellulitis in our cases.

Ninety-eight patients with diagnosis of community-acquired pneumonia and parapneumonic effusion were retrospectively evaluated in order to determine the demographic properties of the patients, etiologic microorganism and the resistance patterns. Ages of study groups were between 2 to 16 years (mean 6.5 +/- 3.5 years) and 56 of 98 patients (56%) were male. There were four groups: Pneumonia (Group 1, n: 57), pleural effusion-medical treatment (Group 2, n: 18), pleural effusion-tube thoracostomy (Group 3, n: 19), and pleural effusion-operative treatment (Group 4, n: 4). Pre-admission antibiotic use was up to 84% in study groups. Evaluation of seasonal dispersion revealed that 86.7% of patients were admitted to hospital in the October-May period. Blood cultures were positive in 4 of 98 patients (4%). Nine of 27 (33.3%) pleural effusion cultures were positive and 4 of them revealed Streptococcus pneumoniae. Intermediate penicillin resistance was found in 1/4 of S. pneumoniae isolates (25%). Our study illustrates the problems in the diagnosis and management of pediatric respiratory tract infections in developing countries. Chest X-ray together with erythrocyte sedimentation rate (ESR) was also shown to be important in classifying lower respiratory tract infections. Increase in the usage of specific viral serologic studies will probably lower the percentage of antibiotic usage and lower the costs of cultures.

Controlled trials concerning adjuvant dexamethasone therapy in bacterial meningitis do not point unequivocally to a beneficial effect on hearing ability. We investigated the remote adverse outcomes of pneumococcal meningitis and, if any, beneficial effects of adjuvant dexamethasone therapy on hearing ability. Fifty-five subjects who experienced pneumococcal meningitis between 1987-97 were divided into two groups as 25 subjects who did not receive dexamethasone (Group 1) and the remaining 30 subjects who did (Group 2). All subjects underwent pure tone thresholds estimation. There were a total of 11 subjects (20%) with sensorineural hearing impairment (SNHI): 6 in the first group (24%) and 5 in the second group (16%). Although there was no statistically significant difference in the SNHI ratio between the groups, all the subjects who used adjuvant dexamethasone therapy suffered only minimal-borderline SNHI, whereas 2 patients in Group 1 had moderate-serious SNHI. Even though adjuvant dexamethasone therapy had no statistically significant impact on hearing ability after long-term follow-up, its use may be a good choice in terms of preventing serious SNHI.

Erythema nodosum (EN), which is a rare skin manifestation among children, is precipitated by a range of infectious and non-infectious diseases. The purpose of this study was to evaluate the epidemiology, etiology, clinical manifestations and course of EN among children. A total of 10 patients diagnosed with EN between January 2000 and March 2004 at Hacettepe University Ihsan Doğramaci Children's Hospital, Pediatric Infectious Diseases Outpatient Clinic, were studied retrospectively. The study population consisted of five girls and five boys, with a mean age of 8.8 +/- 3.3 years (range, 4-14 years). In five of the 10 children (50%), the etiology of EN was established: three had streptococcal infection and two were diagnosed as primary tuberculosis; the etiology of EN could not be determined in 50% of the cases. The duration of the recovery of lesions varied from 4 to 12 days (mean, 8.2 +/- 2.6 days). Our data confirm the predominance of streptococcal infections among the etiologic factors while also considering tuberculosis as a causative factor among children with EN in Turkey.

Salmonella osteomyelitis is rarely seen and vertebral involvement by this organism is very rare, especially in childhood. Salmonella should be considered in the list of etiologic agents of osteomyelitis in sickle cell disease. Herein we report a five-year-old boy with sickle cell disease and Salmonella paratyphi B spondylitis who was diagnosed with atypical clinical findings of infection. We would like to emphasize the importance of differentiation between osteomyelitis and infarction even if there is no obvious sign of infection in the sickle cell patient even at atypical localization.

Mumps is still one of the most common childhood diseases in areas where national immunization has not been implemented. Although central nervous system manifestation is not so uncommon, hydrocephalus secondary to mumps is very rare. In this report, we present a toddler who developed severe hydrocephalus during mumps infection, which resolved via timely cerebral spinal fluid (CSF) drainage. We would like to emphasize early intervention for CSF external drainage.

We report the case of a five-year-old healthy boy who was admitted with abscess and soft tissue infection between the left wrist and the distal end of the forearm. Postero-anterior X-ray examination of the forearm showed a transverse line on the radius; however, further comparative radiographic examinations of the forearm were not compatible with fracture. Enterobacter cloacae was identified in the pus culture and initial intravenous empiric treatment with sulbactam-ampicillin was continued. Although the microorganism was susceptible to the empiric antimicrobial agent, at the eighth day of the treatment, inflammatory drainage was still present so further evaluations were performed. Ultrasonography of the forearm and wrist revealed only collection; magnetic resonance imaging showed a foreign body on the anterior distal section of the left forearm. The patient underwent operation and a 22 mm wooden foreign body was removed. Detailed history after removing a tree branch particle revealed that the boy had recently fallen from a tree causing an abrasion over the left wrist. The postoperative course was uneventful and clinical response was excellent in two days. In view of this case report, we would like to emphasize the importance of medical history and imaging studies in cases of cellulitis that do not respond to appropriate antimicrobial therapy. Another point to be kept in mind is that Enterobacter cloacae, which is very rarely reported as a causative agent for cellulitis, could be the etiological agent in cases after plant thorn injuries.

Respiratory syncytial virus (RSV) is the leading cause of lower respiratory tract infections in infants and young children worldwide. This study was conducted to determine the prevalence of RSV among high-risk children admitted with respiratory symptoms in a developing country. This is a multicenter study conducted among children less than 24 months of age and admitted to the hospital with respiratory symptoms. The inclusion criteria included: lower respiratory tract symptoms on admission, gestational age less than 35 weeks, and admission age less than six months, or children less than 24 months of age with a diagnosis of bronchopulmonary dysplasia requiring medical treatment or intervention during the last six months or with an uncorrected congenital heart disease (other than patent ductus arteriosus). Nasopharyngeal samples were obtained with one of the three standard methods: nasopharyngeal aspirate, nasopharyngeal wash or nasopharyngeal swab. RSV antigen was determined by enzyme immunoassay using Abbott TESTPACK RSV (No. 8100/2027-16). Statistical analysis was performed using Student's t-test and chi-square test. In this study, 332 children (135 females, 40.7%; 197 males, 59.3%) were included, and the nasopharyngeal specimens of 98 (29.5%) children were determined to be RSV-positive. There were no differences in sex, age of gestation, age of admission, family education, number of siblings and smoking at home for RSV-positive and -negative cases. Furthermore, underlying disease and duration of hospital and intensive care unit stay were similar among groups. Only otitis media was more common among RSV-positive cases. No fatality at hospital was recorded. Frozen samples revealed more negative results. Most cases presented during winter and the number of RSV-positive cases was higher in cold and economically poor areas. Premature children and children with underlying medical condition acquire RSV irrespective of other sociodemographic risk factors, and most of them are hospitalized. Thus, an RSV vaccine seems the most effective mode of protection to decrease morbidity and mortality.

Autoimmune thrombocytopenic purpura is estimated to be one of the most common acquired bleeding disorders of children. The pathogenesis involves the generation of autoantibodies against the normally expressed glycoproteins on the platelet membranes. These antibody-coated platelets in turn are destroyed by the spleen and other reticuloendothelial organs. Although the disease can occur without an identifiable etiology, many underlying pathologies, including infections, can be found. We report the mumps virus as a rare etiology of secondary autoimmune thrombocytopenic purpura.

This study was performed to determine hepatitis B and measles seroprevalence among the population under 30 years of age in Turkey. Blood samples of 2,683 subjects from eight provinces of Turkey were studied. Measles IgG was determined by hemagglutinin inhibition method, and hepatitits B surface antigen (HBsAg), anti-hepatitis B surface antibody (anti-HBs) and anti-hepatitis B core antibodies (anti-HBc) were determined by ELISA method. Overall seropositivity for measles was found to be 59.6%. There was a significant difference in seropositivity among provinces. The seropositivity was found to increase with age. The overall seropositivities for HBsAg, anti-HBs and anti-HBc were found to be 5.4%, 17% and 15.1%, respectively. The seroprevalences differed significantly among provinces. Although seroprevalence for anti-HBs and anti-HBc increased with age, HBsAg seropositivity did not change significantly after one year of age. Seroprevalence was not affected by sex. It was concluded that every effort should be given to vaccinate infants as early as possible for hepatitis B and that the coverage of infancy measles vaccination should be increased with a second dose.

Streptococcus pneumoniae isolates resistant to penicillin and other antibiotics have been increasing in many parts of the world. The aim of this study was to evaluate the antimicrobial susceptibilities to penicillin and other commonly used agents in 98 isolates recovered between 1997 and 1998 from clinical specimens from children, and to determine the serotypes/serogroups related to resistance. Susceptibility to penicillin was determined by E-test and disk diffusion tests were used for the other antimicrobials. Serotyping was performed on all the isolates by the quelling reaction. The rates of intermediate- and high-level resistance to penicillin were 29.6% and 2%, respectively. Overall resistance to trimethoprim-sulfamethoxazole was high (46%), of which 21% coexisted with penicillin resistance. Resistance rates to erythromycin and chloramphenicol were 5% and 1%, respectively. Five isolates were multi-drug resistant. The most frequent serotypes associated with penicillin resistance were serotypes 19, 23, 6, 9 and 15.

The aim of this study was to determine how long it takes blood culture to become positive using a blood culture system that can be monitored continuously in pediatric patients. Data were collected prospectively on 1,000 positive blood culture results from a tertiary pediatric university hospital from April 2000 to May 2002. The laboratory used the BACTEC 9120 fluorescent blood culture system. Patient's age ranged from less than a day to 20 years of age (mean 3 years). Five hundred and four cultures (50.4%) out of 1,000 yielded coagulase negative staphylococcus (CNS), 81 (8.1%) S. aureus, 53 (5.3%). Pseudomonas and 50 (5.0%) Klebsiella species. Of the 504 coagulase negative staphylococcal blood culture isolates, 314 (62.3% of CNS) were regarded as skin contaminants. Of the 1,000 cultures, 9.6% were reported as positive in the first day, 27.8% in the second day, 54.7% in the third day, 77.0% in the fourth and 89.4% in the fifth day. There was no association between previous antibiotic usage and the period required for isolate recovery. The clinician can expect to get results of positive blood cultures with susceptibility data, at a rate of 77.1% by day four and almost 90% by day five of sampling in the bacteriemic patient. Blood cultures yielding coagulase negative staphylococci in the first three days almost always show bacteremia with those microorganisms.

A 50-day-old girl with swelling and ecchymosis of right hand dorsum after DTP vaccination on ipsilateral deltoid area was referred to the pediatric infectious disease outpatient unit with a presumed diagnosis of gangrenous cellulites. Physical examination and laboratory evaluation revealed intramuscular bleeding as a result of vitamin K deficiency. We would like to emphasize the importance of both vitamin K prophylaxis in the newborn to prevent hemorrhagic disease of the newborn and of the education of persons administering vaccines about this very basic aspect of pediatrics for early recognition.

Fucosidosis is a rare, autosomal recessive lysosomal storage disorder caused by a severe deficiency of alpha-L-fucosidase. Here we present a 27-month-old male who was referred to us for evaluation of developmental delay, which was first detected at age six months. His past medical history was also remarkable for recurrent pulmonary infections and myoclonic seiures. His family history revealed that he was the first living child from a consanguineous marriage. He had a younger sister who died at five months of age from pneumonia who had facial resemblance to the proband, developmental delay and a congenital heart defect. Physical examination revealed length: 81 cm (25-50p), weight: 10.2 kg (25-50p), and head circumference: 49 cm (50-75p). He had a coarse face, hepatomegaly and generalized spasticity. His initial laboratory examination revealed negative urine screening column chromatography for mucopolysaccharidosis. His X-ray findings were consistent with mild form of dysostosis multiplex. Based on clinical and laboratory features, fucosidosis was suspected. Fucosidase enzyme activity was zero. In addition to fucosidosis, thyroid function tests indicated primary hypothyroidism. This is, to the best of our knowledge, the fourth case of fucosidosis diagnosed in Turkey.

Hyperprolinemia type II (HP II) is a rare inherited metabolic disease due to the deficiency of pyroline-5-carboxylate dehydrogenase. It is generally believed to be a benign condition although some patients have neurological problems such as refractory convulsions. Here we report a six-year-old girl with HP II who admitted to our hospital with recurrent seizure refractory to multiple antiepileptic drugs. She was the third child of healthy, consanguineous parents. The family history was negative for neurological and renal disorders. On physical examination, she had no facial dysmorphy; the anthropometric measurements, and systemic and neurological examinations were normal. Mental and motor development was appropriate for her age. Laboratory findings revealed elevated levels of proline, glycine, and ornithine in serum and pyrroline-5-carboxylate and hydroxyproline in urine. Cerebral computerized tomography and magnetic resonance imaging were both normal. Electroencephalogram showed a very active epileptic abnormality; partial control of seizures was achieved by two antiepileptics. Increased plasma glycine and ornithine levels are the unique features of our case when compared to the other HP II cases reported in the literature.

A retrospective review was conducted on 132 patients aged between two and 15 years with cervical lymphadenitis and/or with abscess formation to determine the epidemiologic and clinical presentation of these infections. The most common locations were the upper anterior cervical space (43.2%) and the submandibular space (27.3%). The duration of symptoms ranged from 12 hours to 20 days. Results of the pus cultures were available in 31 patients (23.5%). Of these, 16 cultures (51.6%) were positive. The isolated organisms were Staphylococcus aureus (50%), Staphylococcus epidermidis (31.3%), group A beta-hemolytic streptococcus (12.5%), Streptococcus pneumoniae (6.3%) and Escherichia coli (6.3%). One of the specimens yielded mixed organisms (Staphylococcus epidermidis and Streptococcus pneumoniae). Penicillin resistance was documented in six (37.5%) of the 16 gram-positive bacteria isolated from the pus culture. Both throat and blood cultures were available in all 132 patients. Seven throat cultures (5.3%) were positive for group A beta hemolytic streptococci, whereas five blood cultures (3.8%) were reported to have bacterial growth. Sixty-seven patients (50.8%) were treated with ampicillin-sulbactam, 53 patients (40.1%) with ampicillin-sulbactam and ornidazole and 12 patients (9.1%) with ceftriaxone parenterally. The mean duration of hospital stay related to the infection was 7.30 +/- 3.89 days (range, 2-28 days). The mean period for downsizing of the cervical mass by half was 4.05 +/- 2.05 days, and the recovery period (total antibiotic usage period) was 13.72 +/- 5.33 days. All of the patients had an uneventful recovery without complications. Results of both throat and blood cultures were not predictive for etiologic agents in our study group. Since ultrasonographic evaluation of each patient has limited additional benefits in clinical management, it must be reserved for selected cases to document abscess formation.

Thyroxin (T4) binding globulin (TBG) the major thyroid hormone transport protein in humans. Congenital or acquired problems lead to TBG excess. Inheritance of TBG excess follows an X-linked pattern. A 21-month-old boy with ichthyosis was referred to the Pediatric Endocrinology Clinic with high levels of thyroid hormones (TT3 = 325 ng/dl, TT4 23 microg/dl, FT3 = 3.49 pg/dl, FT4 = 1.44 ng/dl, TSH = 2.48 microIU/ml). He was clinically euthyroidic. Thyroid gland was normal in size and homogeneous. Thyroid autoantibodies were negative. TSH responded normally to thyroid releasing hormone (TRH) stimulus. TBG was elevated (56 microg/ml). Family investigation revealed high levels of TBG in mother grandfather, and an uncle. To our knowledge, no other TBG excess with ichthyosis has been reported in the literature.

Promyositis is a term used to denote primary pyogenic infection of the skeletal muscle. Because striped muscle tissue is normally resistant to bacterial infection, pyomyositis is very rare. In tropical countries, pyomyositis accounts for about 4% of hospital surgical admission, but it is far less common in temperate climates. It is more common in adults and especially in men, but it can occur at any age. We would like to present an 8-month-old infant to make pediatricians aware of the possibility of pyomyositis in cases of a mass over muscle, or of children complaining of joint pain or muscle aches even in the infancy period.

An 11-year-old prepubertal girl with a history of metabolically poorly controlled type 1 diabetes for six years was diagnosed with diabetic nephropathy based on persistent overt proteinuria, hypertension, and renal biopsy findings typical of diabetic nephropathy. This case illustrates that diabetic nephropathy can develop even before puberty when metabolic control of the disease is not sufficient.

This study was conducted to determine the hepatitis A virus (HAV) seroprevalence in nine provinces representative of Turkey as a whole. These provinces are representative of the country's geographical location, and demographic, economic and social characteristics. In each province, sample sizes were determined using published data on HAV seroprevalence, and sample sizes for each province and for the cluster were calculated for each group of subjects under the age of 30 for seroprevalence estimates within a 95% confidence interval. The samples were selected by a cluster method, and the planned recruitment was a total of 4,800 subjects, including 600 subjects each from five large provinces (Istanbul, Ankara, Izmir, Adana, Diyarbakir) and 450 subjects from each of the remaining four provinces (Samsun, Erzurum, Trabzon, Edirne). These numbers were distributed in accordance with the percentages for age groups in five-year increments starting from age five for the population under the age of 30 living in the rural and urban areas in each province. This study of 4,462 subjects under the age of 30 in nine provinces of Turkey identified an overall HAV seroprevalence rate of 71.3%. The distribution of HAV seroprevalences by age showed a steady increase from one year of age from 42.7% to 91.1% at 25-29 years of age. HAV seroprevalence was slightly higher in female subjects (73%) than in male subjects (69.3%). By educational status, seroprevalences were comparable except in young children under age six. Seroprevalence was notably higher in large families with six and more members (80.1%) than in small families with five or fewer members (66.7%). According to our study results, 50% of Turkish children are seropositive for HAV by the age of 10 years. We believe the date support the need for a routine primary immunization policy in Turkey and the development of effective prophylactic programs after possible exposure. Consequently, an immunization policy can be developed for each region according to its epidemiological conditions.
