Preschool children with asthma during the Covid-19 pandemic: fewer infections, less wheezing.

INTRODUCTION: A few studies have already investigated preschool children with asthma during the pandemic. The purpose of this research was to investigate how preschool children with asthma were affected by the precautionary measures adopted during the pandemic. METHODS: Preschool children with asthma aged 18-60 months evaluated in our clinic in March-May 2019, before the Covid-19 pandemic, were included in the study. The lockdown continued during March, April, and May 2020. The questionnaires and asthma symptom control tests for preschool children with asthma in 2019 and 2020 were then evaluated. RESULTS: Sixty-three preschool children with asthma, 37 boys and 26 girls, aged 18-60 months (median 47) were included in the study. The median number of upper respiratory tract infections (URTIs) and lower respiratory tract infections (LRTIs), and the use of antibiotics were significantly lower in 2020 than 2019 (p<.01). The median numbers of the pediatric emergency department (PED) visits and hospitalizations were also lower in 2020 than in 2019 (p<.05). In 2019, 31 children with asthma were well controlled, 28 were partly controlled, and 4 were uncontrolled, compared to 58 well controlled, four partly controlled, and one uncontrolled in 2020 (p<.01). CONCLUSIONS: Preschool children with asthma have been positively affected in terms of PED admission, hospitalization, and asthma symptom control in association with the Covid-19 pandemic and the resulting lockdown measures. This study revealed that wheezing decreased significantly in the absence of respiratory infection in preschool children with asthma. Namely, fewer infections meant less wheezing.

Demographic and clinical characteristics of newborn pneumothorax patients and their effects on respiratory function tests during childhood.

PURPOSE: Pneumothorax is defined as the presence of air between the parietal and visceral leaves of the pleura, resulting in lung collapse. The aim of this study was to evaluate the respiratory functions of these patients when they reach school age and to reveal whether they cause permanent respiratory pathology. METHODS: The files of 229 patients who were hospitalised in a neonatal intensive care clinic had received a diagnosis of pneumothorax and had undergone tube thoracostomy were included in a retrospective cohort review. The respiratory functions of participants in the control and patient groups were evaluated using spirometry in a prospective cross-sectional study design. RESULTS: The study found the rates of pneumothorax to be higher in males, term infants and after caesarean delivery, mortality was 31%. Among patients who underwent spirometry, those with a history of pneumothorax had lower forced expiratory volume at timed intervals of 0.5 to 1.0 (FEV1), forced vital capacity (FVC), FEV1/FVC, peak expiratory flow (PEF) and forced expiratory flow 25-75% (MEF25-75). FEV1/FVC ratio was significantly lower (p < 0.05). CONCLUSION: Patients treated for pneumothorax in the neonatal period should be evaluated for obstructive pulmonary diseases during childhood using respiratory function tests.

Characteristics of children with cat sensitivity: a prospective cross-sectional study.

BACKGROUND: Animal dander is one of the most common respiratory allergens in children, and there is evidence that cat sensitivity is a risk factor for asthma and allergic rhinitis. In this study, it was aimed to evaluate children with cat sensitivity and to identify their demographic and clinical characteristics. METHODS: Patients who were found to be sensitive to cats following skin prick tests performed in our allergy clinic over a period of one year (and two control groups), were included in the study. Patients in the study and control groups filled in a questionnaire including demographic and clinical characteristics. RESULTS: The prevalence of cat sensitivity in our allergy clinic was 6% (182/3033). The most common diagnoses in patients were 41.8% allergic rhinitis, 25.8% asthma, and 13.2% allergic rhinitis + asthma. Allergic rhinitis symptoms were the most prevalent symptom associated with cat contact (29.4%), whereas 28% of the patients were asymptomatic. Only 17.3% had a cat at home and 13.4% had cat exposure apart from home but having a cat at home was significantly higher than the control groups (p < 0.05). Eosinophilia was present in 54.6% of the patients, and 17.3% had blood tIgE levels of >1000 IU/mL. Eosinophilia and tIgE levels were significantly higher than both control groups (p < 0.05). DISCUSSION: Cat ownership can affect the development of cat sensitivity but the majority of patients with cat sensitivity are not cat owners. Elevated tIgE levels (> 1000 IU/mL) may be associated with cat sensitivity, these patients should be evaluated for cat sensitivity, even if they do not report symptoms with cat contact.

The peripheral blood inflammatory patterns in the control levels of asthma in children.

OBJECTIVE: Asthma is the most common chronic inflammatory disease of childhood, but there are no useful and easily accessible laboratory tests routinely used in the diagnosis and follow-up of this disease in children. Therefore, this study aimed to investigate the roles of white blood cell (WBC) count, platelet count, mean platelet volume (MPV), and eosinophil percentage as full blood count inflammatory markers in evaluating the control level and follow-up of asthma in the pediatric age group. METHODS: A retrospective review of patient records and files of 3,580 patients diagnosed with asthma at the University of Health Sciences in Ankara, Turkey was performed. Patients who met inclusion/exclusion criteria were divided into two groups based on the asthma control level: controlled and uncontrolled. Laboratory data were compared according to the asthma control levels, drug use status, and atopy status of the patients. RESULTS: A total of 348 patients between 4 and 18 years of age, who were followed-up with the diagnosis of asthma, were included in this study. A significant difference was found between the controlled and uncontrolled groups of asthma patients in terms of the eosinophil percentage (mean ± SD, respectively; 3.493 ± 2.24; 4.992 ± 3.43; p = .003). When patients were grouped according to their asthma control levels and atopy status, only the eosinophil percentages were different in the logistic regression analysis (odds ratio = 1.276, 95% confidence interval = 1.113-1.462). CONCLUSION: Our study showed that the percentage of eosinophils can be used as an asthma control parameter, but additional prospective studies would be desirable to confirm our results.

Anaphylaxis and epinephrine autoinjector use in pediatric patients with cutaneous mastocytosis.

BACKGROUND/OBJECTIVES: Mastocytosis is a complex disorder presenting with a broad clinical spectrum. In this study, we aimed to evaluate the frequency of systemic symptoms, necessity of the usage of epinephrine autoinjectors (EAI), and factors affecting the use of EAI among pediatric patients with cutaneous mastocytosis (CM). METHODS: The study population was composed of 53 patients with CM. The clinical data were collected from the medical files. A questionnaire about the patient's anaphylaxis experiences and treatment attitudes toward EAI was performed. RESULTS: Thirty-three of 53 patients were male (62.3%), and the median age of the study participants was 80 months. Anaphylaxis was reported in two patients (3.7%). One of the patients had drug-induced anaphylaxis, and the other had venom-induced anaphylaxis. Three patients (5.6%) reported a personal history of EAI use due to systemic symptoms. Patients with higher serum tryptase level and cases of familial mastocytosis had more systemic symptoms (P = .012 and P = .010, respectively). The patient rate of compliance with EAI for prescription filling and carrying the EAI was 88.7% and 79.2% respectively. 41.5% of parents were hesitant to use EAI when necessary, although they were trained for the use of it by medical staff. CONCLUSIONS: The rate of anaphylaxis in patients with CM in the current study wassignificant and justifies prescribing EAI. Detailed education and counseling on EAI usage are needed to reduce parental hesitancy.

Revaccination following suspected vaccine-triggered hypersensitivity reactions: experience of a tertiary care centre.

INTRODUCTION AND OBJECTIVES: Suspected hypersensitivity reactions (HRs) associated with vaccines are frequently reported, but confirmed cases of vaccine-triggered HRs are rare. Suspected HRs should be distinguished from actual HRs. The aims of this study are to identify the rate of actual vaccine-triggered hypersensitivity in patients who were referred to the paediatric allergy clinic due to a suspected HR and to explore the rate of revaccination in a real clinical setting. MATERIALS AND METHODS: A retrospective study was performed with a group of preschool children who were evaluated by skin and/or provocation tests (PTs) for the suspected HRs following vaccination. RESULTS: A total of 26 paediatric patients (61.5% male; median age 9 months) with a previous history of suspected vaccine-triggered HR were included. In this group, 69.2% and 38.5% of the patients had a pre-existing atopic disease and an immediate reaction (emerging <1 hour after vaccine administration), respectively. Skin rash was the most frequent clinical presentation (96.1%). Vaccine-triggered anaphylaxis was reported in six patients (23.1%). Measles-mumps-rubella was the most frequently suspected vaccine causing HRs. The skin test positivity with the suspected vaccine was 4%, whereas PTs revealed no reaction after reimmunisation in 76.9% (20/26) of the study participants tested. CONCLUSIONS: Most incidents of skin rashes after immunisation are not suggestive of actual HRs. The results in the current study showed that the majority of the patients presenting with suspected HRs tolerated revaccination, including those with a previous history of suspected anaphylaxis. Revaccination of these patients is safe with adequate precautions. It is absolutely essential to be equipped for the management of anaphylaxis.

A More Comfortable Method of Skin Prick Testing in Children Ages 0-2 to Decrease Symptoms of Pain.

BACKGROUND: Skin prick testing (SPT) is the best initial diagnostic method for individuals of all ages who have potential allergies. AIM: We aimed to investigate if recent breastfeeding has any effect on reducing the pain of children before SPT. DESIGN: Prospective, randomized, single-blinded study. SETTINGS: Academic hospital specialized in pediatrics. PARTICIPANTS/SUBJECTS: Sixty-four out of seventy-five children requiring SPT within ages 0-2 were included. METHODS: All participants in this study were breastfed children, and that group assignment randomized them to the control group (n = 32) if children breastfed 30-90 min. prior to arriving for SPT, and study group of children (n = 32) who were also breastfed 30-90 minutes prior to arriving for SPT who were then breastfed again just prior to the beginning of the SPT. The FLACC pain scale was used to test the sensitivity of all children for pain before, during, and 15 minutes after the SPT. The effect of breastfeeding on the pain score and the duration of crying were compared among groups. RESULTS: Both groups were similar according to age, gender, and other socio-demographic characteristics (p > .05). The percentage of children that cried during SPT was significantly higher in the control group than the study group (p = .002). The FLACC pain scale values were significantly lower in the study group (p < .001). CONCLUSION: Recent breastfeeding before SPT is correlated with less crying by possibly reducing the perceived pain of children ages 0-2.

Is Oral Food Challenge as Safe Enough as It Seems?

BACKGROUND: Oral food challenges (OFCs) assist in the diagnosis of food allergies and are essential to determine whether an allergy has been outgrown. During the OFC, a medical procedure e introduces foods suspected to be allergenic orally in increasing doses. Mild skin reactions such as urticaria or rarely serious life-threatening reactions such as anaphylaxis may develop. OBJECTIVE: In this study, we aimed to retrospectively evaluate the clinical and laboratory characteristics of patients who experienced anaphylaxis during open OFCs in a tertiary care children's hospital. METHODS: Patients who underwent OFCs to confirm the presence of a food allergy or to assess tolerance status at the University of Health Sciences, Ankara, Dr. Sami Ulus Maternity and Children Training and Research Hospital, Pediatric Allergy and Immunology Outpatient Clinic between 1 January 2013 and 1 February 2016, were included in the study. Patients' data were obtained retrospectively from electronic medical records and challenge chart reviews. RESULTS: A total of 623 OFCs were performed during the period studied. Nine patients (1.4%) between 13 and 67 months of age (mean age: 38.3 months) developed anaphylaxis during their OFC. CONCLUSION: OFCs should be performed in a hospital or outpatient office under medical supervision that is adequate for anaphylaxis intervention by an allergy specialist. Close observation of objective and subjective symptoms is essential during the challenge because there are no laboratory tests that can predict an anaphylactic diagnosis or the severity of the reaction.

Sleep Patterns and Development of Children with Atopic Dermatitis.

INTRODUCTION: Atopic dermatitis (AD) is a chronic inflammatory disease that begins in early childhood. Sleep problems have increased in children with AD. The aim of this study was to evaluate sleep patterns and the development of children with AD at an early age. METHODS: This is a cross-sectional study consisting of a total of 80 children aged 0-36 months with AD. Patients were evaluated by the Brief Infant Sleep Questionnaire and International Guide for Monitoring Child Development. RESULTS: The median age (IQR) of the patients was 6 (4.25-9) months, 63.7% of them were male and 50% of them had sleep problems. Male sex (OR: 3.78, p = 0.024, 95% CI, 0.083-0.837), patients with AD who were in the first 3 months after diagnosis (OR: 3.56; 95% CI, 1.220-10.43, p = 0.020), and moderate-severe AD (OR: 5.09; 95% CI, 1.649-15.748, p = 0.005) were determined as risk factors for sleep problems. In all, 12.5% of the patients needed support for one or more developmental areas (gross motor skills, expressive language and communication, receptive language, fine motor skills, relationship, and play). Developmental delay was higher in patients with sleep problems (p = 0.037). Multiple siblings (OR: 14.381; 95% CI, 1.557-132.871, p = 0.019) and the presence of sleep problems (OR: 8.011; 95% CI, 1.764-36.387, p = 0.024) were found to be risk factors for developmental delay. CONCLUSION: Boys with moderate-severe AD within the first 3 months of diagnosis were at increased risk for sleep problems. Children with AD who have multiple siblings and sleep problems should be evaluated for developmental delay and monitored closely.

Assessment of thiol/disulphide homoeostasis and ischaemia-modified albumin and their relationship with disease severity in children with chronic urticaria.

BACKGROUND: The pathogenesis chronic urticaria (CU) hasn't been fully understood. In recent years, it has been shown that thiol-disulphide homoeostasis, as an antioxidant system, plays important roles in both healthy individuals and various diseases. In different ischaemia-reperfusion states, high oxidative stress causes ischaemia-modified albumin (IMA) generation. AIM: To investigate thiol/disulphide balance and IMA level in children with CU and their association with disease severity. METHODS: Thirty children with CU and 20 healthy children as controls, aged 1-18 years, were included in this cross-sectional study. In all subjects, total thiol, native thiol, disulphide levels and IMA levels were measured in plasma by spectrophotometry. Disulphide/native thiol, disulphide/total thiol and native thiol/total thiol ratios were calculated. The disease severity was rated by Urticaria Activity Score (UAS). RESULTS: In the children with CU, the levels of native thiol (375.56 ± 56.22 µmol/L) and total thiol (415.69 ± 54.75 µmol/L) were significantly lower than the control group (475.20 ± 71.87 and 511.20 ± 73.73 µmol/L, respectively) (p = 0.000, p = 0.000). The ratio of native/total thiol * 100 was lower in patients than the control group (p = 0.002). IMA was significantly higher in the patient group than control group (p = 0.000). No significant correlation was found between UAS and thiol/disulphide homoeostasis (p > 0.05). The disulphide levels, disulphide/native thiol and disulphide/total thiol levels were found to be higher in patients with positive family history for autoimmune disorders than those without (p < 0.05). CONCLUSION: In children with CU, impaired thiol/disulphide homoeostasis and increased IMA suggest that oxidative stress may play role in the disease pathogenesis.

Pediatric cutaneous mastocytosis and c-KIT mutation screening.

Background: Cutaneous mastocytosis (CM) is a heterogeneous disease that commonly presents with skin lesions in childhood. Objective: In this study, we aimed to evaluate the clinical and laboratory test results of our patients with CM to ascertain prognostic factors by using patients' long-term follow-up results and to determine c-KIT (receptor tyrosine kinase) mutation from peripheral blood samples, which might be responsible for the etiopathogenesis of pediatric mastocytosis. Methods: The clinical observation data of 32 children who had been diagnosed with CM were retrospectively researched. Exon 8, 9, 11, 13, and 17 c-KIT gene locations were analyzed from DNA material that was obtained from peripheral blood samples of all the patients by using polymerase chain reaction analysis and automatic DNA sequencing. Results: The tryptase level was higher in patients with familial cases and in cases of patients who had gastrointestinal mediator releasing symptoms (p = 0.017, p = 0.038, respectively). The use of clarithromycin and the use of vitamin D were determined as triggers for mediator release. Hypogammaglobulinemia was found in six patients (18.8%). Indoor tobacco exposure was seen to be higher in patients not in remission than in patients in remission (59.1% and 20%, respectively) (p = 0.040). Allergic diseases were observed in 80% of patients in complete remission and 22.7% of patients not in remission (p = 0.002). Concomitant allergic diseases were found to be good prognosis markers among pediatric patients with CM. No c-KIT mutation was discovered in any of the patients. Conclusion: In this study, tobacco exposure would seem to be a barrier for remission, and concomitant allergic diseases were seen to be a good prognosis marker. Evaluation of peripheral c-KIT mutation had no diagnostic contribution among pediatric patients with CM in contrast to adults.

The Relevance of Nasal Provocation Testing in Children with Nonallergic Rhinitis.

BACKGROUND: It is important to understand that allergic rhinitis, whether seasonal or perennial, may be difficult to distinguish clinically from the nonallergic forms of rhinitis. OBJECTIVE: This study aimed to investigate the presence of local allergic rhinitis (LAR) in children who have allergic rhinitis symptoms in the absence of skin test positivity and specific IgE by performing a nasal provocation test (NPT). METHODS: Our study followed a case-controlled, prospective design. Twenty-eight patients and 30 healthy children were included in the study in a pollen-free season. The NPTs with a grass mix, Dermatophagoides pteronyssinus (DP) and D. farinae (DF) allergens were performed with an interval of 1 week. The total symptom score and visual analog scale, nasal eosinophilia and pulmonary function tests were evaluated before and after each NPT. The change to nasal flow and resistance was recorded by anterior rhinomanometry. RESULTS: The symptom frequencies before the NPTs were as follows: nasal congestion 100%; itching 82.1%; rhinorrhea 75% and sneezing 71.4%. The NPT was positive in 7 (25%) patients. In the NPT-positive group there was a statistically significant decrease in nasal flow at the concentrations of 10 and 100 IR/ml for DF (p = 0.026, p = 0.031, respectively). In the NPT-positive group total nasal resistance for DP was increased at the concentrations of 0.1 and 10 IR/ml, and for DF at 10 and 100 IR/ml (p = 0.049, p = 0.041, p = 0.022, p = 0.035, respectively). CONCLUSIONS: We emphasize that the diagnosis of LAR should be taken into consideration by pediatricians and pediatric allergy specialists.

Is Patch Testing with Food Additives Useful in Children with Atopic Eczema?

BACKGROUND: Atopy patch testing is a useful way to determine delayed-type hypersensitivity reactions to foods and aeroallergens. Although food additives have been accused of worsening atopic eczema symptoms, according to recent studies the role of food additives in atopic eczema remains unclear. The purpose of our study was to investigate food additive hypersensitivity in a group of children with atopic eczema by using standardized atopy patch testing and to determine the role of food additive hypersensitivity in atopic eczema. METHODS: Thirty-four children with atopic eczema and 33 healthy children were enrolled in the study. Children who consumed foods containing additives and did not use either antihistamines or local or systemic corticosteroids for at least 7 days prior to admission were enrolled in the study. All children were subjected to atopy patch testing and after 48 and 72 hours their skin reactions were evaluated by using the guidelines. RESULTS: Positive atopy patch test results were significantly higher in the atopic eczema group. Forty-one percent of the atopic eczema group (n = 14) and 15.2% (n = 5) of the control group had positive atopy patch test results with food additives (p = 0.036) (estimated relative risk 1.68, case odds 0.7, control odds 0.17). Carmine hypersensitivity and the consumption of foods containing carmine, such as gumdrops, salami, and sausage, were significantly higher in the children with atopic eczema. CONCLUSION: This is the first study investigating hypersensitivity to food additives in children with atopic eczema. Our results indicate that carmine may play a role in atopic eczema.

Characteristics of Children with Acute Carbon Monoxide Poisoning in Ankara: A Single Centre Experience.

The purpose of the study was to define characteristics of children with acute carbon monoxide poisoning. Eighty children hospitalized with acute carbon monoxide poisoning were recruited prospectively over a period of 12 months. Sociodemographic features, complaints and laboratory data were recorded. When the patient was discharged, necessary preventive measures to be taken were explained to parents. One month later, the parents were questioned during a control examination regarding the precautions that they took. The ages of the cases were between one month and 16 yr. Education levels were low in 86.2% of mothers and 52.6% of fathers. All families had low income and 48.8% did not have formal housing. The source of the acute carbon monoxide poisoning was stoves in 71.2% of cases and hot-water heaters in 28.8% of cases. Three or more people were poisoned at home in 85.1% of the cases. The most frequent symptoms of poisoning were headache and vertigo (58.8%). Median carboxyhemoglobin levels at admission to the hospital and discharge were measured as 19.5% and 1.1% (P < 0.001). When families were called for re-evaluation, it was determined that most of them had taken the necessary precautions after the poisoning incident (86.3%). This study determined that children with acute childhood carbon monoxide poisoning are usually from families with low socioeconomic and education levels. Education about prevention should be provided to all people who are at risk of carbon monoxide poisoning before a poisoning incident occurs.

Is there a need for repetition of skin test in childhood allergic diseases? Repetition of skin test and allergic diseases.

BACKGROUND: Skin prick tests are widely used to determine sensitivity in allergic diseases. There is limited information about the natural history of skin sensitization tests and factors that affect them. It was aimed to determine the changes in skin test results and the factors affecting the reactivity of skin tests after a period of approximately four years in children with allergic disease. METHODS: SPT of 170 patients among 2485 children with asthma and/or allergic rhinitis and/or atopic dermatitis, who underwent SPT between 2005 and 2007, were repeated after an interval of at least 3 years. RESULTS: The mean age was 10.7 ± 3.1 (5-18) years and 70% of the patients were male. In total 66 (39.0% of the study population) had a different skin tests result in follow-up. Alterations: loss of sensitivity in 18 (11%) patients, the formation of a new sensitivity in 37 (22%) patients, and 11 (6%) both gained and lost sensitization. The presence of atopy in the family, the presence of allergic rhinitis and IgE elevation significantly predicted the incidence of new sensitization. The presence of sensitization to multiple allergens significantly predicted the incidence of loss of sensitization. CONCLUSIONS: It is found that there was an alteration of sensitization in 4/10 children at the end of the average 4-year period. The presence of family atopy, the presence of allergic rhinitis and serum total IgE elevation were risk factors for the development of new sensitization. On the other hand sensitization to multiple allergens was risk factors for the loss of sensitization.

Circulating rotaviral RNA in children with rotavirus antigenemia.

BACKGROUND: Rotavirus antigenemia is a common phenomenon in children with rotavirus diarrhea, but information is scarce on aspects of this phenomenon, such as genotype specificity, presence of intact viruses and correlation between genomic RNA and antigen concentration. Such information may help in understanding rotavirus pathogenesis and eventually be useful for diagnosis, treatment and prevention. METHODS AND FINDINGS: Serum samples were collected from children who presented at hospitals with diarrhea. Antigenemia was present in 162/250 (64.8%) samples from children with rotavirus diarrhea. No specific rotavirus genotype was found to be associated with antigenemia. Rotavirus particles could not be found by electron microscopy in concentrated serum from children with high levels of antigenemia. In passaged rotavirus suspension a significant correlation (r=0.9559; P=0.0029) was found between antigen level and viral copy number, but no significant correlation (r=0.001480; P=0.9919) was found between antigenemia level and viral copy number in serum. When intact rotavirus was treated with benzonase endonuclease, genomic double-stranded (ds) RNA was not degraded, but when sera of patients with antigenemia were treated with benzonase endonuclease, genomic dsRNA was degraded, indicating genomic dsRNA was free in sera and not inside virus capsid protein. CONCLUSIONS: Antigenemia is present in a significant number of patients with rotavirus diarrhea. Rotavirus viremia was absent in the children with rotavirus diarrhea who participated in our study, and was not indicated by the presence of antigenemia. The significance of circulating rotavirus antigen and genomic dsRNA in serum of patients with diarrhea deserves further study.

Growth, tolerance and safety outcomes with use of an extensively hydrolyzed casein-based formula in infants with cow's milk protein allergy.

Objective: To evaluate growth, tolerance and safety outcomes with use of an extensively hydrolyzed casein-based formula (eHCF) in infants with cow's milk protein allergy (CMPA). Methods: A total of 226 infants (mean ± SD age: 106.5 ± 39.5 days, 52.7% were girls) with CMPA who received eHCF comprising at least half of the daily dietary intake were included. Data on anthropometrics [weight for age (WFA), length for age (LFA) and weight for length (WFL) z-scores] were recorded at baseline (visit 1), while data on infant feeding and stool records, anthropometrics and Infant Feeding and Stool Patterns and Formula Satisfaction Questionnaires were recorded at visit 2 (on Days 15 ± 5) and visit 3 (on Days 30 ± 5). Results: From baseline to visit 2 and visit 3, WFA z-scores (from -0.60 ± 1.13 to -0.54 ± 1.09 at visit 2, and to -0.44 ± 1.05 at visit 3, p < 0.001) and WFL z-scores (from -0.80 ± 1.30 to -0.71 ± 1.22 at visit 2, and to -0.64 ± 1.13 at visit 3, p = 0.002) were significantly increased. At least half of infants never experienced irritability or feeding refusal (55.7%) and spit-up after feeding (50.2%). The majority of mothers were satisfied with the study formula (93.2%), and wished to continue using it (92.2%). Conclusions: In conclusion, eHCF was well-accepted and tolerated by an intended use population of infants ≤ 6 months of age with CMPA and enabled adequate volume consumption and improved growth indices within 30 days of utilization alongside a favorable gastrointestinal tolerance and a high level of parental satisfaction.

Serum sickness-like reaction in children due to cefditoren.

We describe the case of a 7-year-old boy with urticaria, fever, and arthritis that appeared 10 days after starting cefditoren therapy for acute tonsillopharyngitis, which was diagnosed as a serum sickness-like reaction due to this medication.
