Background. This study aimed to evaluate Pediatric Appendicitis Score (PAS), diagnostic delay, and factors responsible for possible late diagnosis in children <4 years compared with older children who were operated on for suspected appendicitis.Method. 122 children, between 1 and 14 years, operated on with appendectomy for suspected appendicitis, were retrospectively analyzed. The cohort was divided into two age groups: ≥4 years (n=102) and <4 years (n=20).Results. The mean PAS was lower among the younger compared with the older patients (5.3 and 6.6, resp.;P=0.005), despite the fact that younger children had more severe appendicitis (75.0% and 33.3%, resp.;P=0.001). PAS had low sensitivity in both groups, with a significantly lower sensitivity among the younger patients. Parent and doctor delay were confirmed in children <4 years of age with appendicitis. PAS did not aid in patients with doctor delay. Parameters in patient history, symptoms, and abdominal examination were more diffuse in younger children.Conclusion. PAS should be used with caution when examining children younger than 4 years of age. Diffuse symptoms in younger children with acute appendicitis lead to delay and to later diagnosis and more complicated appendicitis.

In Exp. 2 of Siegler's 1976 study a faulty quasi-experimental design was used. The stated results, that older and younger children with apparently equal initial performance derived different benefits from identical experience, can also be explained by a confounding with regression toward the mean. These effects are a result of a selective matching of subjects from two age groups on a fallible variable correlated with age.

An analysis of the spermatogenic condition and of the weights of testes from about 450 brown-headed cowbirds (Molothrus ater) was made to determine the annual cycle of this species at London, Ontario, and to ascertain variation in the cycle due to age. Testes of birds more than 1 year old (adult) reached maximal weights in late April and early May coincident with the beginning of egg-laying, and about 3 weeks before the testes of 1-year-old birds (yearlings) reached their maximal weight. The mean weights of testes of adults were usually greater, often significantly so, than those of yearlings. From about May 23 to June 23 there were no statistically significant differences in the weights of testes from the two age groups. Beginning in late June, the weights of testes declined rapidly in both age groups and reached a minimum in August. Minimal weights of testes persisted in captive birds until February.Large amounts of sperm were present in the testes of adults in mid-April and of yearlings in late April well in advance of maximal testicular weights. Sperm production occurred in most birds until early July but had ceased in most by late July.Testes, apparently undergoing regression, were noted significantly (p <.005) more frequently in adults than in yearlings in May and early June at the height of the breeding season. The significance of this observation and some aspects of testicular regression, previously unrecorded, are discussed. Adult birds are more sedentary than most yearlings in the breeding season and, unlike the latter, habitually associate with the same female. These behavioral differences may be related to the observed differences between the age groups in the testicular cycle.

ABSTRACTIn order to examine whether children adjust their phonetic speech categories, children of two age groups, five-year-olds and eight-year-olds, were exposed to a video of a face saying /aba/ or /ada/ accompanied by an auditory ambiguous speech sound halfway between /b/ and /d/. The effect of exposure to these audiovisual stimuli was measured on subsequently delivered auditory-only speech identification trials. Results were compared to a control condition in which the audiovisual exposure stimuli contained non-ambiguous and congruent sounds /aba/ or /ada/. The older children learned to categorize the initially ambiguous speech sound in accord with the previously seen lip-read information (i.e. recalibration), but this was not the case for the younger age group. Moreover, all children displayed a tendency to report the stimulus that they were exposed to during the exposure phase. Methodological improvements for adjusting such a response bias are discussed.

Background: Despite the considerable increase in anaphylaxis frequency, there are limited studies on clinical features of anaphylaxis in children in developing countries. Objective: We aimed to analyze the demographic and clinical features of anaphylaxis in children in Turkey by comparing different age groups and triggers. Methods: Medical records of 147 children, ages 0‐18 years, diagnosed with anaphylaxis between 2010 and 2019 were retrospectively analyzed. Results: The mean ± standard deviation age at first anaphylaxis episode was 5.9 ± 5.2 years, with a male predominance (63.9%); 25.2% were infants and 52.4% were < 6 years of age at their first anaphylaxis episode; 78.2% were atopic, with the highest frequency in children with food-induced anaphylaxis (FIA). The home (51.7%) was the most frequent setting. The overall leading cause of anaphylaxis was food (44.2%), which was more frequent at < 6 years of age, followed by drugs (28.6%) and bee venom (22.4%), both were more frequent among older children (>6 years). The patients with venom allergy had the highest rate of rapid onset of symptoms (p < 0.001). Gastrointestinal symptoms were observed significantly more in infants (48.6%) and in children with FIA (38.5%); cardiovascular symptoms were more frequently observed in children > 6 years of age (48.6%) and in children with drug-induced anaphylaxis (64.3%). Although recurrent anaphylaxis was reported for 23.1% of the patients, it was highest in the patients with FIA (35.9%). Overall, only 47.6% of the patients received epinephrine in the emergency department (ED) and 27.3% were referred to an allergy specialist, with the patients with FIA having the lowest rate for both, 32.3% and 10.8%, respectively. Children with drug-induced anaphylaxis had the highest rate of severe anaphylaxis (57.1%). Conclusion: There is a need to improve anaphylaxis recognition and management in all children regardless of age and trigger. Inadequate treatment was most evident in infants and patients with FIA.

Visual perception is the process by which individuals assign meaning, understanding, and interpretation to what they have seen. The aim of this study was to determine the visual perceptual skills of typically developing Indian children on MVPT-4. A sample of 180 typically developing Indian students were included in the study using convenience sampling method. They were divided in six age groups with age ranging from 6years to 12 years with 30 children in each age group. It was found that visual perceptual skills of typically developing Indian children in 6-12 years of age group can be assessed using MVPT-4. Analysis was done using One-way Anova to compare the mean raw score of each age group. There was a significant difference between the age groups at statistical value of p< 0.001. The score improved with age, signifying refined and matured visual perceptual skills in older children. Age influences visual-perceptual skills of these children. This study also provides a foundation for further researches and highlights the importance of MVPT-4 as a screening tool to be used by the occupational therapist in order to assess the visual perceptual skills of children.

Objective To evaluate peritoneal transport kinetics and its changes over time in children with and without peritonitis, and to record possible differences between children under and over 5.0 years of age. Design A prospective study. The patients underwent a 4hour peritoneal equilibration test (PET) comprising 2.27% dextrose with a dialysate fill volume of 1000 mL/m2 of body surface area (BSA), at baseline and after a mean of 0.8: I: 0.4 years of uninterrupted dialysis. Patients We investigated 28 patients on maintenance peritoneal dialysis at baseline; 10 were under 5.0 years of age. The final PET was performed in 21 patients. Main Outcome Measures Peritoneal equilibration rates for urea (U), creatinine (C), glucose (G), sodium, potassium, phosphate, and albumin (A) were measured. Initial and final peritoneal equilibration rates were compared. Mass transfer area coefficients (MTAC) were calculated for urea, creatinine, glucose, and albumin. Residual dialysate volume was determined. Results Median age at first PET was 7.6 years (range 0.3 -16.6 yr). The mean (±1 SD) 4-hour dialysate-to-plasma (DIP) ratios for U, C, and A were 0.92:1: 0.05,0.70 ± 0.12, and 0.014: I: 0.007, respectively. The mean 4-hour DIDo ratio for G was 0.32: I: 0.10. DIP and DIDo results were similar in the two age groups, and peritoneal membrane function remained stable over the study period. Mean MTAC (:1:1 SD) values were: U, 22.3: I: 4.8; C, 10.9: I: 4.1; G, 11.1: I: 3.3; and A, 0.07: I: 0.03. MTAC data were similar in the two age groups and no significant changes occurred during the study period. Conclusions When the volume tested in children is proportional to BSA, the solute DIP ratios seem to be age-independent. Our data provide evidence that in pediatric patients MTAC is also age-independent.

The purpose of this study was to determine whether a new sustained-release theophylline preparation TheoDur could maintain therapeutic serum theophylline levels in asthmatic children on a 12-hour dosage regimen. Twenty asthmatic children aged 6 to 18 years with a mean of 11.4 years who required continuous theophylline therapy for control of their asthma were enrolled in the study. Each patient's dosage was titrated to achieve a six-hour postdose serum theophylline level between 10 and 20 µg/ml. The patients required a mean ± SEM dose of 10.0 ± 0.54 mg/kg every 12 hours which gave a mean ± SEM six-hour postdose serum theophylline level of 15.65 ± 0.72 µg/ml. At the end of five days on this dosage, the patients were admitted and serum theophylline levels were determined every three hours for 24 hours. The mean ± SEM difference between maximum and minimum serum theophylline levels (ΔTL) for the group was 4.5 ± 0.3 µg/ml. There was not a significant difference in the ΔTL between the two age groups (6 to 9 years, 4.5 ± 0.5 µg/ml and 10 to 18 years 4.5 ± 0.4 µg/ml). In conclusion, TheoDur will maintain therapeutic serum theophylline levels with minimal fluctuations in asthmatic children on a 12-hour dosing schedule.

Heritage language speaking children often show signs of attrition, particularly as they get older and are educated in the majority language of the society where they live. In this study, we tested the hypothesis that simplification is one process of attrition for heritage language speakers. We tested this hypothesis on the expression of motion events among children who are first language speakers of Mandarin Chinese and early second language speakers of English, the majority language in this community. We compared their motion expressions to those of monolingual Mandarin-speaking children living in mainland China. Two age groups were included: younger children (4-6 years, not yet in school) and older children (8-10 years; in school for two to five years). The children watched a cartoon and recounted the story. We coded the motion expressions used in their retellings. The results showed that the older bilingual children showed clear signs of attrition, particularly simplification, but also some signs of cross-linguistic influence from English. These results suggest that attrition in a heritage language can quickly follow the onset of schooling in the majority language.
