The communication patterns of a 3-year-old boy who is blind were observed during 35 videotaped classroom sessions to determine if his echolalic responses varied according to school activity and message category. Analysis revealed that, although the child was expressive with adults, he had difficulty communicating with his peers and in producing…

While unilateral pulmonary venous atresia (UPVA) most commonly presents as an extremely rare late embryological defect resulting in complete occlusion or absence of the PV pathway, it may also be an acquired pathology. We present a 3-year-old boy who presented with mild respiratory distress. Neonatal echocardiographic investigations revealed normal mediastinal anatomy and pulmonary vasculature with a bicuspid aortic valve. However, follow-up Doppler investigation revealed a pulmonary artery size difference with minimal forward flow and reverse flow during diastole. Absence of the left pulmonary veins and the presence of collaterals draining to the innominate vein confirmed the diagnosis of acquired UPVA. Our case represents the first case of acquired UPVA in conjunction with a normally functioning bicuspid aortic valve. The Doppler flow patterns discussed might be of significant interest to pediatricians, cardiologists and imaging specialists. These findings suggest that acquired UPVA should be considered in the differential diagnosis of such patients when radiographic and echocardiographic findings may rule out other more common diagnoses. While the management of such a condition remains unclear and conservative management was agreed upon for our patient, the vulnerability of such cases warrants timely diagnosis and routine monitoring.

Midaortic syndrome (MAS) is a rare vascular disease that commonly causes renovascular hypertension. The lumen of the abdominal aorta narrows and the ostia of the branches show stenosis. MAS is associated with diminished pulses in the lower extremities compared with the upper extremities, severe hypertension with higher blood pressure in the upper rather than lower extremities, and an abdominal bruit. The clinical symptoms are variable, and recognition in children with hypertension can aid early diagnosis and optimal treatment. Hypertension with MAS is malignant and often refractory to several antihypertensive drugs. Recently, radiologic modalities have been developed and have led to numerous interventional procedures. We describe the case of a 3-year-old boy presenting with left ventricular hypertrophy whose severely elevated blood pressure led to the diagnosis of idiopathic MAS. This case highlights the importance of measuring blood pressure and conducting a detailed physical examination to diagnose MAS. This is the first reported case of idiopathic MAS diagnosed in childhood in Korea. PMID:28018454

The term 'hemiconvulsion-hemiplegia-epilepsy syndrome' (HHE) was first used by Gastaut et al. to describe the se-quential combination of unilateral or predominantly unilateral clonic seizures (hemiconvulsion), occurring during the first 2 years of life, immediately followed by an ipsilateral flaccid hemiplegia lasting 7 or more days. In the following phase partial epileptic seizures occur. We report a case of HHE syndrome in a 3-year-old boy with partial seizures (hemiconvulsion lasting 15-30 minutes) followed by left hemiplegia and hyporeflexia. Magnetic resonance imaging showed diffuse and high signal hyperintensity of the whole right cerebral hemisphere. Diffusion-weighted images showed a reduction of the apparent diffusion coefficient in the subcortical region. Magnetic resonance arterio-graphy showed a narrow flow signal in the distal territory of the right middle cerebral artery. The authors emphasize the importance of neuroradiological findings in early diagnosis and in the follow-up of HHE syndrome.

A 3-year-old boy referred for persistent tongue bleeding was diagnosed with a rare self-mutilating disease that had also affected his lip and fingers. He underwent multiple odontectomy and partial glossectomy and continues to undergo behavior therapy and on-demand splints and restraints. He has stopped self-biting and has gained appetite and weight. Lesch-Nyhan Syndrome can cause significant morbidity including self-inflicted oral hemorrhage and emergent measures are not easily decided. The long-term management of its neurobehavioral symptoms is problematic and multidisciplinary, and health providers remain challenged to find the best treatment, prolong lifespan and improve quality of life within their respective contexts.

We present a rare case of a 3-year-old boy with an odontogenic myxoma (OM) involving the orbita. Including our case, only nine cases of OM have been reported to involve the eye in children.There is no gold standard for treatment of OM in children with orbital involvement. The recurrence rate of OM in children seems low, which advocates for less invasive surgery. A gentle resection of the OM was carried out. The floor and medial wall of the orbit was reconstructed immediately using a non-resorbable Medpor implant with passive adaptation. Reconstruction with a Medpor implant in children has rarely been reported in the literature. No clinical or radiological recurrence was observed 24 months after surgical removal, and the patient presented with symmetric appearance and normal vision.

Prader-Willi syndrome (PWS) is a genetic disorder which has widespread developmental consequences including motor, cognitive and language delay. Previous research on PWS children has focused primarily on phonological development and dysfluency. In the present study, the lexical development of a boy with PWS was investigated in a series of 18 play…

Cat scratch disease is caused by a facultative intracellular Gram-negative bacteria, Bartonella henselae. This disease is transmitted by cat scratches or bites. The typical form is a large and rough adenopathy, with no general signs. In a few cases, the symptoms are aspecific and various, which makes the diagnosis difficult. A 3-year-old child presented a prolonged fever with an aspecific skin eruption and hepatosplenic lesions seen 1 month after the beginning of the disease, which led to the diagnosis of hepatosplenic cat scratch disease. An adapted antibiotic therapy completely cured the disease.

Chromosome analysis was performed on a 3-year-old boy because of bilateral radioulnar synostosis and demonstrated a mosaic karyotype 46,XY/47,XYY/48,XYYY. He had minor facial anomalies and mild intellectual delay. He appears to be the youngest patient reported with this rare chromosome complement. His father, mother, and brother had normal chromosomes. Fluorescence in situ hybridization (FISH) was performed on the propositus and his father with the Y chromosome heterochromatic probe (pHY3.4) to add to the evaluation of mosaicism. 17 refs., 3 figs., 2 tabs.

Ornithine transcarbamylase deficiency is the commonest urea cycle disorder which is transmitted in X-linked inheritance. It is mainly characterized in males by acute encephalopathy and hyperammonaemia with fatal outcomes in both classical neonatal and late-onset types. We report a 3-year-old healthy Hong Kong Chinese boy who presented with acute encephalopathy and coma after three days of gastroenteritis. He had no focal neurological deficit and brain CT imaging was normal. His plasma ammonia (54 micromol/L) and glutamine (747 micromol/L) concentrations were normal. The only biochemical abnormalities detected were marked orotic aciduria (700 micromol/mmol creatinine) and elevated urinary uracil. He regained consciousness spontaneously after three days under intensive care with parenteral fluid therapy. He recovered completely without any neurological deficits. Five months after discharge, urinary uracil concentration remained elevated despite normalized orotic acid concentration. Finally, ornithine transcarbamylase deficiency was diagnosed by DNA analysis. A missense mutation of arginine-to-glutamine substitution on amino acid 277 (p.R277Q) was revealed to be a late-onset mutant. Our case strengthens the argument that in any child with coma or acute encephalopathy of undetermined cause, genetic analysis of the OTC gene and the measurement of urinary uracil concentration remain the most reliable indicators of late-onset OTCD during acute and even quiescent phases. Existing neonatal screening programmes for inheritable metabolic disorders fail to detect late-onset variants. Therefore, a high clinical suspicion is a key to correct and timely diagnosis, especially in those patients with atypical presentations.

Toxic epidermal necrolysis syndrome (TENS) is a severe but rare skin reaction leading to epidermal desquamation of greater than 30% of the TBSA. It is most commonly precipitated by the administration of medication. Frequent complications of this syndrome include local wound infections, respiratory, mucocutaneous, and ocular complications. Ecthyma gangrenosum (EG) is a rare disease characterized by a milliary seeding of the cutaneous tissue with Gram-negative bacteria; it is most commonly seen in immunocompromised individuals. Here we report a 3-year-old boy who developed EG subsequent to TENS. Although he had a complicated and prolonged hospital course, he survived these series of events. To our knowledge, this is the first reported case of TENS/EG in the pediatric population, and the first report of survivability following these illnesses.

Mycoplasma pneumoniae is a common cause of respiratory tract illness in children. Among the most common extrapulmonary manifestations are disorders of the central nervous system, including meningitis, meningoencephalitis, cerebellitis, polyneuropathy, acute disseminated encephalomyelitis, and Guillain-Barré syndrome. Guillain-Barré syndrome, also known as acute inflammatory demyelinating polyradiculoneuropathy, is an acute-onset, immune-mediated disorder of the peripheral nervous system. The central nervous system is usually intact in patients with Guillain-Barré syndrome. However, there have been some reports of an association of Guillain-Barré syndrome with central nervous system involvement in children. We report a 3-year-old boy with M. pneumoniae infection associated with Guillain-Barré syndrome and encephalitis. Both serum anti-GM1 ganglioside (IgG and IgM) and anti-galactocerebroside IgG antibodies were detected in our patient: the former in the earlier stage of the disease, and the latter in the later stage. We speculate that anti-GM1 ganglioside was associated more with encephalitis, and anti-galactocerebroside antibody was associated more with GBS in our case. Our patient is the youngest report of Guillain-Barré syndrome with central nervous system involvement, and the first report of a pediatric patient with associated M. pneumoniae infection. Such cases are rarely reported, but highlight the need for awareness of the association of the infection with Guillain-Barré syndrome with central nervous system involvement.

We present a case of hyperimmunoglobulin E (hyper-IgE) syndrome in a three year old boy. There are many pitfalls in diagnosing this disease in the very young population, mainly due to the ambiguity of some diagnostic criteria in this population. Recognizing this syndrome early in life can potentially be very beneficial to the patients involved and the medical system as a whole. Early diagnosis can lead to fewer diagnostic tests, fewer referrals, and more focused exams, thus potentially reducing medical cost while also reducing the number of serious infections later in life, including those which are potentially fatal. Additionally, a wellknown association between lymphoma and hyper-IgE syndrome has been established; while no recommendations are currently in place for screening, early diagnosis could help medical providers have a higher threshold for diagnosis of this disease.

In recent years, we have been observing an increased proportion of atopic diseases in children after solid organ transplantation. The pathogenesis of post-transplantation allergy is not completely understood and probably involves several factors, including immunosuppressive therapy. In this paper we present a case of 3-year old boy, after orthotopic heart transplantation at 6 months of age, with symptoms of food allergy associated with atopic dermatitis and changes in the orofacial area. The mentioned symptoms and elevated levels of total and specific IgE occurred with a year of transplant. Because of failure to achieve remission after typical allergy therapy we suspected that the reason of allergy in this case can be immunosuppressive therapy. PMID:26336506

Intracranial teratoma is a rare neoplasm derived from omnipotent germinal cells that can contain mesoderm, endoderm and/or ectoderm layer tissue. Histologically teratomas are characterized by abnormal structures like teeth or bone that can be further subdivided into mature and immature according to the presence of incompletely differentiated tissue. Characteristic intracranial teratomas are space-occupying lesions in the pineal region and often present with hydrocephalic symptoms due to aqueduct stenosis. A 3-year-old boy presented with a peracute hemiparesis, fatigue and speech deficit. MRI diagnostics showed a cystic, partially solid, inhomogeneous contrast-enhancing formation at the top of the tectum mesencephali with consecutive aqueduct compression. The patient underwent a sub-occipital craniotomy via a supracerebellar approach and complete resection was achieved. The histopathological examination mainly showed mature tissue of ectodermal, mesodermal and endodermal origin. However, small areas of undifferentiated neuroectodermal tissue within an optic vesicle formation were detected, leading to the diagnosis of an immature teratoma. In due course, the patient was discharged in good health without neurological deficits. To our knowledge, optic vesicle-containing intracranial germ cell tumors are extremely rare. Here we report a unique case with immature neuroectodermal tissue within an optic vesicle formation in an otherwise mature teratoma.

We report a 3-year-old Peruvian girl, born to non-consanguineous parents. At the age of 8 months, she had a severe pneumonia complicated with empyema that required thoracic drainage and mechanical ventilation. Although no microorganisms were isolated, the patient recovered with broad-spectrum antibiotics. Since that date, she has presented multiple episodes of pneumonia and recurrent episodes of bronchospasm. At 1 year 5 months of age, the patient began with recurrent episodes of oropharyngeal, vaginal, and skin candidiasis, which improved transiently after using oral azole drugs. At 2.5 years of age, she was admitted with lupus-like syndrome, including serositis, hemolytic anemia, thrombocytopenia, and positive antinuclear (1:80) and dsDNA (1:10) autoantibodies. Available immunologic testing was not contributory. Imaging studies revealed bilateral ethmoidal sinusitis and mild hepatomegaly. Bone marrow analysis did not showed evidence of leukemia or myelodysplasia, while renal biopsy concluded mild mesangial proliferation. Genetic studies revealed a pathogenic heterozygous signal transducer and activator of transcription 1 gain-of-function mutation (WT/P293L). The clinical status and lung function of the patient has worsened progressively. She has not achieved an optimal response to therapy, including high-dose intravenous immunoglobulin, GM-CSF, prophylactic antibiotics and antifungal drugs, so we plan to perform hematopoietic stem cell transplantation.

The aim of the present study was to evaluate the prevalence of malocclusion traits and sucking habits among 3-year-old children. A sample of 457 3-year-old children (234 girls and 223 boys) was obtained from three Public Dental Health clinics in Orebro County Council, Sweden. Data from clinical examination and a questionnaire were used to determine malocclusion traits, sucking habits, snoring and breathing pattern including nocturnal breathing disturbances. The results showed that 70% had one or more malocclusion traits at 3 years of age. The most common malocclusion traits were anterior open bite (50%), Class II occlusion (26%), increased overjet (23%) and posterior crossbite (19%). The prevalence of sucking habit was 66% and dummy sucking was dominating and in connection with more malocclusion traits than finger/thumb sucking. A significant association was found between the sucking habits and the most prevalent malocclusions, anterior open bite, Class II occlusion, increased overjet and posterior crossbite. In conclusion, the prevalence of malocclusion traits in 3-year-old children was high. Sucking habits was highly prevalent and dummy sucking resulted in more malocclusion traits than finger/thumb sucking did.

In the context of increasing travel to the tropics, outpatient services are more frequently confronted with non-domestic diseases in Europe. A 3-year old child presented with a painful tumor of the scalp. After incision of the furuncle-like lesion, we extracted a larva of the botfly Dermatobia hominis. Botflies are mainly encountered in Central and South America; they should be considered if patients demonstrate a furuncle-like lesion and have returned from a holiday in these endemic regions.

Although the structure of executive function (EF) during adulthood is characterized by both unity and diversity, recent evidence suggests that preschool EF may be best described by a single factor. The latent structure of EF was examined in 228 3-year-olds using confirmatory factor analysis. Children completed a battery of executive tasks that differed in format and response requirements and in putative working memory and inhibitory control demands. Tasks appeared to be age appropriate, with adequate sensitivity across the range of performance and without floor or ceiling effects. Tests of the relative fit of several alternative models supported a single latent EF construct. Measurement invariance testing revealed less proficient EF in children at higher sociodemographic risk relative to those at lower risk and no differences between boys and girls. At 3years of age, when EF skills are emerging, EF appears to be a unitary, more domain-general process.

A 3-year-old patient was referred to the oral and maxillofacial department with a fracture of the orbital floor. Due to the lack of clinical symptoms, a conservative approach was chosen. After 3 weeks, an enophthalmos developed. The orbital floor reconstruction was successfully performed through a transconjunctival approach. This case highlights the rarity of pure blowout fractures in young children. The specific presentation and diagnostics of orbital floor fractures in children and the related surgical planning and intervention are discussed. PMID:24436749

Desmoplastic fibroma is a rare benign fibrogenic, locally aggressive, primary bone tumor. It is the intraosseous counterpart of soft tissue aggressive fibromatosis. The lesion may very rarely appear as a superficial bone lesion arising from the periosteum; in such cases, a soft tissue mass with changes in the adjacent bone is evident. Periosteal lesions are very rare in the literature; diagnosis is usually based on the radiographic findings, and histological proof of the tumor origin is missing. A periosteal desmoplastic fibroma of the distal tibial metaphysis in a 3-year-old boy is presented. Radiographic investigation included plain radiographs and computed tomography imaging. Both demonstrated a soft tissue lesion involving the superficial bone tissues with non-aggressive looking borders and a pressure effect with a sclerotic rim in the bone. The lesion was excised, and the surgical as well as the histological findings indicated the diagnosis of a desmoplastic fibroma of bone arising from the periosteum. No recurrence was detected 5 years after surgery.

Until 1960, 179 cases of infection with Nocardia asteroides had been described in the world literature. Seventeen cases in children were reported by 1963. The organism is a common saprophyte in nature with probably a world-wide distribution. Infection can be primary but is more common in patients with underlying malignancy, auto-immune disease or preceding tuberculosis. Sulphonamides, particularly sulphadiazine, are the drugs of choice in treatment; the value of antibiotics is less clearly established. The indications for surgical treatment have not yet been defined. We record a further case of primary pulmonary nocardiosis in a 3-year-old child. Images PMID:6035802

We report a case of a 3 year old boy with bilateral profound sensorineural hearing loss diagnosed from New Born Hearing Screening, with severe form of VACTERL association. He was referred to our Cochlear Implant Unit for assessment with regard to the possibility of cochlear implantation. MRI findings have showed bilateral vestibulocochlear cystic abnormalities. Only single nerve noted within the IAM on the right and likely single nerve within the IAM on the left. Hence, decision was made not to offer cochlear implantation. This is the first report of severe bilateral cochleovestibular nerve abnormalities to be associated with VACTERL.

This survey was conducted to determine the testability, distribution and associations of ocular biometric parameters in Chinese preschool children. Ocular biometric examinations, including the axial length (AL) and corneal radius of curvature (CR), were conducted on 1,688 3-year-old subjects by using an IOLMaster in August 2015. Anthropometric parameters, including height and weight, were measured according to a standardized protocol, and body mass index (BMI) was calculated. The testability was 93.7% for the AL and 78.6% for the CR overall, and both measures improved with age. Girls performed slightly better in AL measurements (P = 0.08), and the difference in CR was statistically significant (P < 0.05). The AL distribution was normal in girls (P = 0.12), whereas it was not in boys (P < 0.05). For CR1, all subgroups presented normal distributions (P = 0.16 for boys; P = 0.20 for girls), but the distribution varied when the subgroups were combined (P < 0.05). CR2 presented a normal distribution (P = 0.11), whereas the AL/CR ratio was abnormal (P < 0.001). Boys exhibited a significantly longer AL, a greater CR and a greater AL/CR ratio than girls (all P < 0.001). PMID:27384307

Two studies investigated the influence of external rewards and social praise in young children's fairness-related behavior. The motivation of ninety-six 3-year-olds' to equalize unfair resource allocations was measured in three scenarios (collaboration, windfall, and dictator game) following three different treatments (material reward, verbal praise, and neutral response). In all scenarios, children's willingness to engage in costly sharing was negatively influenced when they had received a reward for equal sharing during treatment than when they had received praise or no reward. The negative effect of material rewards was not due to subjects responding in kind to their partner's termination of rewards. These results provide new evidence for the intrinsic motivation of prosociality-in this case, costly sharing behavior-in preschool children.
A 3-year-old intact male Perro de Presa Canario dog was presented with acutely inflamed and edematous right hind limb, scrotum, prepuce, and an enlarged left carpus. Two weeks later the dog returned with weight loss, draining tracts in the right hind limb, dermal nodules, a palpable abdominal mass, and uveitis in the left eye. The dog succumbed to his illness 2 days later and a widely disseminated round cell tumor compatible with histiocytic sarcoma was diagnosed following postmortem examination.

This study uses data from 2,309 biological fathers who participated in the Fragile Families and Child Well-Being Study (FFCWS) to examine associations between psychosocial characteristics and levels of corporal punishment (CP) toward their 3-year-old children over the past month. Results indicate that 61% of the fathers reported no CP over the past month, 23% reported using CP once or twice, and 16% reported using CP a few times in the past month or more. In multivariate models controlling for important sociodemographic factors as well as characteristics of the child, fathers' parenting stress, major depression, heavy alcohol use, and drug use were significantly associated with greater use of CP, whereas involvement with the child and generalized anxiety disorder were not. Girls were less likely to be the recipient of CP than were boys, and child externalizing behavior problems but not internalizing behavior problems were associated with more CP.

Initial symptoms of Rocky Mountain spotted fever (RMSF), a tick-borne illness caused by Rickettsia rickettsii, are nonspecific and include headache, gastrointestinal disturbances, malaise, and myalgias, followed by fever and rash. The classic triad of fever, rash, and history of tick exposure is uncommon at presentation. Clinical manifestations of RMSF range from virtually asymptomatic to severe. Because of the potentially fatal outcome of RMSF, presumptive clinical diagnosis and empiric antimicrobial therapy can be critical. We present the case of a 3-year-old girl from New York State who presented with fever and rash.

Researchers have long been puzzled by the challenge English passive constructions present for language learners, with adult-like comprehension and production emerging only around the age of 5. It has therefore been of significant interest that researchers of other languages, including the Bantu language Sesotho, have reported acquisition of the passive by the age of 3 (Demuth, 1989). Such reports have typically been based on spontaneous production data, calling for further investigation. This study carried out a series of experiments with Sesotho-speaking 3-year-olds, testing their ability to comprehend the passive, produce the passive, and generalize novel verbs to passive frames. The results showed that passive comprehension was good, with no effect of actional/non-actional verb type. Elicited production of the passive was also good, with no difference between adversive and non-adversive verbs. Finally, all participants made both active and passive generalizations to novel verbs. These findings provide strong evidence that Sesotho-speaking 3-year-olds have robust, abstract knowledge of passive syntax. The paper concludes with a discussion of the factors that contribute to the early learning of the Sesotho passive, why acquisition of the passive may be delayed in English, and the implications for understanding grammatical development more generally.

When we are engaged in a joint action, we need to integrate our partner's actions with our own actions. Previous research has shown that in adults the involvement of one's own motor system is enhanced during observation of an action partner as compared to during observation of an individual actor. The aim of this study was to investigate whether similar motor system involvement is present at early stages of joint action development and whether it is related to joint action performance. In an EEG experiment with 3-year-old children, we assessed the children's brain activity and performance during a joint game with an adult experimenter. We used a simple button-pressing game in which the two players acted in turns. Power in the mu- and beta-frequency bands was compared when children were not actively moving but observing the experimenter's actions when (1) they were engaged in the joint action game and (2) when they were not engaged. Enhanced motor involvement during action observation as indicated by attenuated sensorimotor mu- and beta-power was found when the 3-year-olds were engaged in the joint action. This enhanced motor activation during action observation was associated with better joint action performance. The findings suggest that already in early childhood the motor system is differentially activated during action observation depending on the involvement in a joint action. This motor system involvement might play an important role for children's joint action performance.

Forty 3-year-olds learned either 12 standard Blissymbols (SBS) or their enhanced forms (EBS). Results demonstrated that the subjects learned EBS faster than SBS, remembered more EBS than SBS, did not differ in the communicative use of SBS and EBS, and were affected more negatively when presented with the untrained SBS than EBS.

Key Clinical Message A 3-year-old Rhodesian Ridgeback was presented with conjunctivitis, enlargement of the third eyelid and a dorsotemporal deviation of the right eye. A mass within the third eyelid was detected and excised. The histopathologic examination showed a malignant peripheral nerve sheath tumor, which most likely is a neurofibrosarcoma based on immunohistochemistry. PMID:25678975

Epidermoid cysts are a rare entity in the oral cavity and are even less frequent in the floor of the mouth, representing less than 0.01% of all the cases. We present the case of a 3-year-old girl with a growth in the floor of the mouth with 2 months of evolution and without changes since it was discovered by her parents. The lesion was asymptomatic; it did not cause dysphagia, dyspnea, or any other alteration. A CT scan with contrast was done which revealed the location and exact size of the lesion, allowing an intraoral approach for its excision. The histological examination confirmed the clinical speculation of an epidermoid cyst. PMID:25694831

Pediatric mandibular fractures are often the sequelae of facial skeletal injuries in patients with trauma and frequently require hospitalization. Due to the retrusive mid-face position relative to the calvarial prominence, facial fractures are rare in children younger than 5 years of age. Although rare, they most often occur as a result of motor vehicle accidents. The purpose of this report is to describe the management of a mandibular symphysis fracture in a 3-year-old boy with displacement between the primary mandibular left central and lateral incisors. The fracture was reduced and the fractured segment was stabilized under general anesthesia with a prefabricated acrylic splint with circum-mandibular wiring. Children have greater osteogenic potential and faster healing rates than adults; therefore, anatomic reduction in children is best accomplished earlier.

Do words cue children’s visual attention, and if so, what are the relevant mechanisms? Across four experiments, 3-year-old children (N = 163) were tested in visual search tasks in which targets were cued with only a visual preview versus a visual preview and a spoken name. The experiments were designed to determine whether labels facilitated search times and to examine one route through which labels could have their effect: By influencing the visual working memory representation of the target. The targets and distractors were pictures of instances of basic-level known categories and the labels were the common name for the target category. We predicted that the label would enhance the visual working memory representation of the target object, guiding attention to objects that better matched the target representation. Experiments 1 and 2 used conjunctive search tasks, and Experiment 3 varied shape discriminability between targets and distractors. Experiment 4 compared the effects of labels to repeated presentations of the visual target, which should also influence the working memory representation of the target. The overall pattern fits contemporary theories of how the contents of visual working memory interact with visual search and attention, and shows that even in very young children heard words affect the processing of visual information.

Abstract Ascaris lumbricoides infection affects approximately 1.5 billion people globally. Children with environmental and socio-economic risk factors are more susceptible to infestation, with serious complications such as intestinal obstruction (IO), volvulus, intussusception, and intestinal necrosis. We present the case of a 3-year-old girl who arrived at emergency department with abdominal pain and diarrhea for the last 3 days. The previous day she took an unspecified anthelmintic. Symptoms worsened with vomiting and diarrhea, with expulsion of roundworms through mouth and anus. Physical examination revealed bloating, absence of bowel sounds, abdominal tenderness, and a palpable mass in right hemi-abdomen. Abdominal radiographs showed air-fluid levels with mild bowel distention and shadows of roundworms. The diagnosis of IO by A lumbricoides. infestation was established and surgical approach scheduled. During exploratory laparotomy an intraluminal bolus of roundworms from jejunum to ascendant colon was evident. An ileum enterotomy was performed and worms were removed. Fluid therapy and antibiotics for 72 hours were administered, with posterior albendazol treatment for 3 days. Patient was uneventfully discharged on the tenth day. Reduction in parasitic load by means of improvements in sanitation, health education, and anthelmintic treatment must be implemented in endemic zones to prevent serious life-threatening complications by A lumbricoides. infestation, because some of them require urgent surgical treatment.

Do words cue children's visual attention, and if so, what are the relevant mechanisms? Across four experiments, 3-year-old children (N = 163) were tested in visual search tasks in which targets were cued with only a visual preview versus a visual preview and a spoken name. The experiments were designed to determine whether labels facilitated search times and to examine one route through which labels could have their effect: By influencing the visual working memory representation of the target. The targets and distractors were pictures of instances of basic-level known categories and the labels were the common name for the target category. We predicted that the label would enhance the visual working memory representation of the target object, guiding attention to objects that better matched the target representation. Experiments 1 and 2 used conjunctive search tasks, and Experiment 3 varied shape discriminability between targets and distractors. Experiment 4 compared the effects of labels to repeated presentations of the visual target, which should also influence the working memory representation of the target. The overall pattern fits contemporary theories of how the contents of visual working memory interact with visual search and attention, and shows that even in very young children heard words affect the processing of visual information.

Pilocytic astrocytomas correspond to low-grade gliomas and therefore metastasize exceedingly rare. However, pilocytic astrocytomas are able to and leptomeningeal dissemination may be seen. What are the treatment options of these cases? We present a case report of a 3-year-old child with a pilocytic astrocytoma of the optic chiasm with leptomeningeal dissemination of the spinal meninges. Partial resection of the cerebral tumor has been performed. Since the leptomeningeal dissemination was seen all over the spinal meninges, the child did not undergo further surgical treatment. A wait and watch strategy were followed. Chemotherapy was initiated, if a 25% tumor growth was seen. Leptomeningeal dissemination of a pilocytic astrocytoma is seen so infrequently that no standard therapy is established. Since these metastases may occur even up to 2 decades after primary tumor resection, long-term follow-up is indicated. In case of spinal metastases, surgical treatment should be performed if feasible. Otherwise observation should be possessed and/or chemotherapy should be initiated.

Executive functions enable flexible thinking, something young children are notoriously bad at. For instance, in the dimensional change card sort (DCCS) task, 3-year-olds can sort cards by one dimension (shape), but continue to sort by this dimension when asked to switch (to color). This study tests a prediction of a dynamic neural field model that…

Under most circumstances, children (and adults) can safely assume that the testimony they hear is true. In two studies, we investigated whether 3-year-olds (N = 100) would continue to hold this assumption even if the person who provided the testimony behaved in an uncertain, ignorant, and/or distracted manner. In Study 1, children were less likely…

In 3 studies we explored when 3-year-olds would imitate novel words in utterances produced by adult speakers. Child and experimenter took turns in requesting objects from a game master. The experimenter always went first and always preceded the object's familiar name with a novel adjective (e.g., "the dilsige duck"). In the first 2…

Three studies investigated 3-year-old children's ability to determine a speaker's communicative intent when the speaker's overt utterance related to that intent only indirectly. Studies 1 and 2 examined children's comprehension of indirectly stated requests (e.g., "I find Xs good" can imply, in context, a request for…

Recent studies have established that even infants can determine what others know based on previous visual experience. In the current study, we investigated whether 2-and 3-year-olds know what others know based on previous auditory experience. A child and an adult heard the sound of one object together, but only the child heard the sound of another…

A comparison of the Q3 and Hybrid III 3-year-old crash test dummies is presented in this paper. The performance of the dummies were compared in sixty biofidelity tests, seventy-seven static out-of-position airbag tests and sixty-three calibration tests. Various time histories and other data pertaining to accelerations, deflections, forces and moments are compared. In addition, the ease of positioning, handling, and the durability of the dummies in various out-of-position test configurations was assessed. Both the Q3 and Hybrid III 3-year-old dummies were calibrated to their respective specifications. The Hybrid III 3-year-old met its calibration requirements, while the Q3 did not always meet its own calibration requirements. The calibration specifications of the Q3 dummy need to be re-examined and possibly refined. The biofidelity of the Q3 and Hybrid III 3-year-old dummies were evaluated in both frontal and lateral test modes. Each dummy was evaluated against its own and the other's specified requirements, when possible. In the frontal test mode, the Hybrid III 3-year-old acceptably met all of its requirements. The Q3 dummy did not meet all of its own frontal biofidelity requirements. Based on these results, the Hybrid III 3-year-old is more biofidelic for primarily frontal loading conditions. With respect to the lateral biofidelity specifications, neither the Hybrid III 3-year-old nor the Q3 dummy met the requirements for the thorax and pelvis tests performed. Both dummies met the head drop requirements. Neither dummy is recommended for lateral loading conditions. For lateral testing where only the head is impacted, the Hybrid III 3-year-old could be used. In general, the responses of both dummies were repeatable in both the frontal and lateral biofidelity tests performed. The Hybrid III 3-year-old and the Q3 dummies were evaluated in static out-of-position airbag tests with three different side airbag systems (two seat-mounted and one door-mounted system), and

Background Childhood lead poisoning has not made the list of national public health priorities in Lebanon. This study aims at identifying the prevalence and risk factors for elevated blood lead concentrations (B-Pb ≥ 100 μg/L) among 1–3 year old children. It also examines the need for universal blood lead screening. Methods This is a cross-sectional study of 281 well children, presenting to the pediatric ambulatory services at the American University of Beirut Medical Center in 1997–98. Blood was drawn on participating children for lead analysis and a structured questionnaire was introduced to mothers asking about social, demographic, and residence characteristics, as well as potential risk factors for lead exposure. Children with B-Pb ≥ 100 μg/L were compared to those with B-Pb < 100 μg/L. Results Mean B-Pb was 66.0 μg/L (median 60.0; range 10–160; standard deviation 26.3) with 39 (14%) children with B-Pb ≥ 100 μg/L. Logistic regression analysis showed that elevated B-Pb was associated with paternal manual jobs (odds ratio [OR]: 4.74), residence being located in high traffic areas (OR: 4.59), summer season (OR: 4.39), using hot tap water for cooking (OR: 3.96), exposure to kohl (OR: 2.40), and living in older buildings (OR: 2.01). Conclusion Lead screening should be offered to high-risk children. With the recent ban of leaded gasoline in Lebanon, emphasis should shift to other sources of exposure in children. PMID:12780938

Before children learn the specific meanings of numerals like six, do they know that they represent precise quantities? Previous studies have reported conflicting evidence and have found that children expect numerals to label precise quantities in some tasks but not in others (Condry & Spelke, 2008; Sarnecka & Gelman, 2004). In this article, we present evidence that some of children's apparent successes are best explained not by domain-specific semantic understanding of number but instead by language-general pragmatic abilities. In Experiment 1, we replicated the findings of the previous studies in a within-subject design. When 3-year-olds saw a set labeled with a number (e.g., five) and an item was added, they preferred a new label (six) over the old one, as though they believed that number words have precise meanings. However, when 1 of 2 sets was labeled (e.g., as five) and children were asked to find the same quantity (five) or a new quantity (six), they performed identically whether the original set was changed in quantity or merely rearranged. Thus, when 2 numerals were offered as alternative labels for 1 set, children behaved as though they had precise meanings, whereas when they were asked to determine which of 2 sets a single numeral referred to, they did not. In Experiment 2, children were tested using similar methods but with novel nouns and objects that were transformed, instead of sets. Children showed the identical pattern of results despite lacking meanings for these words, suggesting that their judgments for numerals may not have relied on semantic knowledge that numerals have precise meanings. We propose that children's behavior can be explained by the use of domain-general pragmatic inference and does not require positing domain-specific numerical knowledge.

A 3-year-old Standardbred gelding with a history of pyrexia, persistent hemorrhage from the oral cavity, and a large, soft swelling at the junction of the caudal aspect of the mandibular rami and proximal neck was evaluated. The horse had neutropenia and anemia, with atypical granulated cells in a blood smear. Additional tests confirmed acute myeloid leukemia with basophilic differentiation, which has been reported in humans, cats, dogs, and cattle but not horses. PMID:27708445
The development of 200 3-year-old children was measured, using Gesell parameters of development. The levels of development were matched against the adequacy, or inadequacy, of maternal care and housing, the scales for which were derived from a questionnaire completed by the children's mothers. Housing was not found to affect the children's developmental levels, while the adequacy of maternal care was highly significantly related to satisfactory child development. PMID:420522

Primary liver tumors in children are rare with malignant hepatoblastoma being the most common neoplasm. In this report, we describe the diagnosis and clinical management of a large liver tumor in a 3-year-old child that displayed the features of both, conventional hepatoblastoma and malignant teratoma. Pathological assessment on a pre-operative bioptical specimen showed an immature teratoid tumor with no area of hepatoblastic differentiation present. Histological and immunhistological examination of the resected tumor specimen additionally showed tumor areas of very different differentiation pattern intermixed with each other, namely areas of hepatoblastoma-typical and neuroblastoma-like morphology as well as areas of rhadomyosarcomatous differentiation. After chemotherapy the tumor size increased and an extended right hemihepatectomy was performed. Post-operatively, the general condition of the child improved and adjuvant chemotherapy was started two weeks later. 36 months after initial diagnosis the patient is healthy, in good general condition, and without any sign of residual tumor disease. Overall, we describe the diagnosis and clinical management of a large liver tumor in a 3-year-old child that displayed the features of both, conventional hepatoblastoma and malignant teratoma and was designated as mixed hepatoblastoma and teratoma. Though mesenchymal tumor portions can occur within hepatoblastomas, most commonly osteoid or chondroid, our case is different as it presents a large spectrum of mesenchymal and epithelial differentiation pattern in most of the lesion.

The literature review regarding potential effects of screen media on cognitive development among children under 3 years old, is presented. In this article, cognitive aspects of development include acquisition of language, attention, learning and later school performance. The constant increase of children's access to television is noted, indicating that 60% of infants and toddlers watch TV regularly for 1-2 hours per day. The review included 40 articles and book chapters of significant such as Anderson, Barr, Christakis, Zimmerman, Meltzoff, Courage, Setliff, Troseth. The data was selected from electronic databases of scientific publications: Psychology & Behavioral Sciences Collection, Social Sciences Full Text (H.W. Wilson) and Humanities Full Text (H.W. Wilson) available in Poland. Cited articles provide evidence of the negative impact of exposure to television, media and video on the cognitive functioning of children under 3 years old. The potential impact of watching TV for difficulties in ability to focus attention appears as a core danger. Furthermore, studies suggest a possible connection between early exposure to television and ADHD as well as difficulties with language acquisition, learning and poorer school results.

A case of benign granulomas of the conjunctiva in a 3-year-old girl is reported. Histologic features of the excised conjunctival lesions were consistent with Splendore-Hoeppli phenomenon. This phenomenon is thought to be a granulomatous reaction to an antigen-antibody precipitate related to parasites or fungi. No causative agent is identified in our patient. Immunohistochemical analysis showed no immunoreactivity for immunoglobulin G (IgG), IgM, IgA, or the C3 component of the complement. We propose that the presence of small amelanotic nodular conjunctival tumors should arouse suspicion related to the Splendore-Hoeppli phenomenon even in early childhood.

Dapsone (DDS-diamino diphenyl sulphone) is a sulfone antibiotic being used for a variety of clinical conditions. Poisoning in children by DDS is rarely reported. Poisoning in acute cases will be frequently unrecognized due to relative lack of severe signs and symptoms. Methemoglobinemia is the major life-threatening situation associated with poisoning of DDS. Hence, any delay for medical attention can lead to increased rate of mortality. In this case, we describe acute DDS poisoning in a 3-year-old child and the successful management using intravenous methylene blue. PMID:26488029

Purpose This study investigated the association of axial length (AL) to corneal radius of curvature (CRC) ratio with spherical equivalent (SE) in a 3-year old Asian cohort. Methods Three-hundred forty-nine 3-year old Asian children from The Growing Up in Singapore towards Healthy Outcomes (GUSTO) birth cohort study underwent AL and CRC measurements with a noncontact ocular biometer and cycloplegic refraction using an autorefractor. The ratio of AL to CRC (AL/CRC) was calculated for all the participants, and subsequently AL, CRC, and AL/CRC were analyzed in relationship to SE. Results The SE showed better correlation with AL/CRC (Spearman's correlation coefficient, ρ = −0.53; 95% confidence interval [CI]: −0.66; −0.49; P < 0.001) compared to either AL or CRC alone ([ρ = −0.36; 95% CI: −0.51 to 0.51; P = 0.01] and [ρ = 0.05; 95% CI: −0.04 to 0.17; P = 0.34], respectively). Mean AL/CRC was 2.91 ± 0.06 among myopes and decreased to 2.79 ± 0.06 among hyperopes. Axial length to corneal radius of curvature was strongly correlated with SE in myopes (ρ = −0.78; 95% CI: −3.76; −0.79; P = < 0.001), but not in emmetropes and hyperopes ([ρ = −0.39; 95% CI: −10.73; −0.57; P = 0.01] and [ρ = −0.18; 95% CI: −17.28; 12.42; P = 0.38], respectively). Linear regression adjusted for gender and ethnicity showed a 0.74-diopter shift in SE towards myopia with every 0.1 increase in AL/CRC ratio (P < 0.001, r2 = 0.33). Conclusion The correlation between SE and AL/CRC is stronger than that between AL or CRC alone. This suggests that in a research setting, when cycloplegic refraction is difficult to perform on 3-year-old children, AL/CRC may be the next best reference for refractive error. Translational Relevance In the research setting, AL/CRC may be the next best reference for refractive error over AL alone when cycloplegic refraction is unavailable in 3-year old children.

Infectious diseases precede a significant proportion of acute ischemic strokes in children. Here, we report a case of acute ischemic stroke in a 3-year-old girl with a Mycoplasma pneumonia-associated respiratory tract infection. She developed an acquired prothrombotic state of protein S deficiency and had increased fibrinogen and fibrinogen degradation product levels and increased titer of antinuclear antibodies. However, these conditions were completely alleviated at the 1-month follow-up examination. Infection with M. pneumoniae may cause a transient prothrombotic state that can potentially cause a thrombus. PMID:24223604

We describe the case of a 3-year-old girl with a 15-day clinical history of lower back pain. We diagnosed a spondylodiscitis of vertebral bodies L5–S1 caused by Salmonella species group B that totally recovered with appropriate antibiotic therapy. Spondylodiscitis in children is a rare condition and Salmonella infection is one of the rarest aetiology. A high index of suspicion is needed for prompt diagnosis to ensure better long-term outcome. Microbiological diagnosis is essential for the appropriate choice of antibiotic treatment. PMID:23475989

The present study investigated phonological whole-word measures and consonant accuracy in bilingual and monolingual children to investigate how target approximations drive phonological acquisition. The study included eight bilingual Spanish- and English-speaking 3-year-olds and their monolingual peers (eight Spanish and eight American English). Phonological whole-word measures (pMLU and Proximity) and consonant accuracy (PCC) were calculated on elicited single words. Differences were found on each measure between bilinguals and monolinguals in English, but in Spanish, only the PCC displayed differences between bilinguals and monolinguals. Bilinguals displayed language separation on the pMLU and the PCC but not the Proximity, indicating structural phonological differences between the Spanish and English of bilinguals but commensurate target approximations. This suggests that maintaining a consistent level of phonological proximity to the target is an important factor in phonological acquisition. The measures and their relationships are also discussed.
A 3-year-old girl was reported to have perilunate dislocation. The child had suffered, approximately 18 months before, a repetitive wrist injury by means of frequent pulling and bending of the hand by the father who may have physically abused the child for approximately 2 months. At the age of 3 years and 4 months, we performed the reduction of the perilunate dislocation and the plasty of the dorsal scapholunate ligament using the capsular flap prepared from the extensor retinaculum. The wrist was immobilized for 6 weeks. Two months after surgery, patient started the physiotherapy for 3 months. The patient could flex up the wrist to 40 degrees and extend up to 45 degrees (mobility of the healthy wrist was 60, 50 degrees) during the examination 24 months' post-op. Only the surgical treatment of the perilunate dislocation can lead to obtain the good surgical result. PMID:26788457

The current study examines the processing of upright and inverted faces in 3-year-old children (n = 35). Event-related potentials (ERPs) were recorded during a passive-looking paradigm including adult and newborn face stimuli. We observed three face-sensitive components, the P1, the N170 and the P400. Inverted faces elicited shorter P1 latency and larger P400 amplitude. P1 and N170 amplitudes were larger for adult faces. To examine the role of experience in the development of face processing, the processing of adult and newborn faces was compared for children with a younger sibling (n = 23) and children without a younger sibling (n = 12). Age of sibling at test correlated negatively with P1 amplitude for adult and newborn faces. This may indicate more efficient processing of different face ages in children with a younger sibling and potentially reflects a more flexible face representation. PMID:24118716

Traumatic brain injury caused by drop and traffic accidents is an important reason for children's death and disability. Recently, the computer finite element (FE) head model has been developed to investigate brain injury mechanism and biomechanical responses. Based on CT data of a healthy 3-year-old child head, the FE head model with detailed anatomical structure was developed. The deep brain structures such as white matter, gray matter, cerebral ventricle, hippocampus, were firstly created in this FE model. The FE model was validated by comparing the simulation results with that of cadaver experiments based on reconstructing the child and adult cadaver experiments. In addition, the effects of skull stiffness on the child head dynamic responses were further investigated. All the simulation results confirmed the good biofidelity of the FE model.

Previous studies failed to find evidence for rational action selection in children under 2 years of age. The current study investigated whether younger children required more training to encode the relevant causal relationships. Children between 1½ and 3 years of age were trained over two sessions to perform actions on a touch-sensitive screen to obtain video clips as outcomes. Subsequently, a visual habituation procedure was employed to devalue one of the training outcomes. As in previous studies, 2- and 3-year-olds chose actions associated with an expected valued outcome significantly more often during a subsequent choice test. Moreover, analysis of children's first responses in the post-devaluation test revealed evidence of rational action selection even in the youngest age group (18-23 months). Consistent with dual-process accounts of action control, the findings support the view that the ability to make rational action choices develops gradually.

Background: The oral ingestion of elemental mercury is unlikely to cause systemic toxicity, as it is poorly absorbed through the gastrointestinal system. However, abnormal gastrointestinal function or anatomy may allow elemental mercury into the bloodstream and the peritoneal space. Systemic effects of massive oral intake of mercury have rarely been reported. Case Report: In this paper, we are presenting the highest single oral intake of elemental mercury by a child aged 3 years. A Libyan boy aged 3 years ingested approximately 750 grams of elemental mercury and was still asymptomatic. Conclusion: The patient had no existing disease or abnormal gastrointestinal function or anatomy. The physical examination was normal. His serum mercury level was 91 µg/L (normal: <5 µg/L), and he showed no clinical manifestations. Exposure to mercury in children through different circumstances remains a likely occurrence.

Understanding the cultural and linguistic diversity of young children with hearing loss informs the provision of assessment, habilitation, and education services to both children and their families. Data describing communication mode, oral language use, and demographic characteristics were collected for 406 children with hearing loss and their caregivers when children were 3 years old. The data were from the Longitudinal Outcomes of Children with Hearing Impairment (LOCHI) study, a prospective, population-based study of children with hearing loss in Australia. The majority of the 406 children used spoken English at home; however, 28 other languages also were spoken. Compared with their caregivers, the children in this study used fewer spoken languages and had higher rates of oral monolingualism. Few children used a spoken language other than English in their early education environment. One quarter of the children used sign to communicate at home and/or in their early education environment. No associations between caregiver hearing status and children's communication mode were identified. This exploratory investigation of the communication modes and languages used by young children with hearing loss and their caregivers provides an initial examination of the cultural and linguistic diversity and heritage language attrition of this population. The findings of this study have implications for the development of resources and the provision of early education services to the families of children with hearing loss, especially where the caregivers use a language that is not the lingua franca of their country of residence.

Objectives. We estimated racial/ethnic differences in overweight and obesity in a national sample of 3-year-olds from urban, low-income families and assessed possible determinants of differences. Methods. Survey, in-home observation, and interview data were collected at birth, 1 year, and 3 years. We used logistic regression analyses and adjusted for a range of covariates in examining overweight and obesity differentials according to race/ethnicity. Results. Thirty-five percent of the study children were overweight or obese. Hispanic children were twice as likely as either Black or White children to be overweight or obese. Although we controlled for a wide variety of characteristics, we were unable to explain either White–Hispanic or Black–Hispanic differences in overweight and obesity. However, birthweight, taking a bottle to bed, and mother’s weight status were important predictors of children’s overweight or obesity at age 3 years. Conclusions. Children’s problems with overweight and obesity begin as early as age 3, and Hispanic children and those with obese mothers are especially at risk. PMID:17194857

The objective of this prospective study was to determine the impact of early literacy anticipatory guidance (AG) with provision of books on language development in 3-year-olds in an early literacy program at a University-affiliated inner-city pediatric clinic. The Peabody Picture Vocabulary Test (PPVT-III) and the Expressive One Word Picture Vocabulary Test (EOWPVT-R) were administered to 33-39-month-old children exposed to an early literacy program, which included AG and provision of an age-appropriate book at each well-child visit starting at 2 months old. Children with developmental delays were excluded. Parental surveys on literacy and demographic data were obtained. Univariate and multivariate analyses were performed. Sixty-four children were evaluated; 88% African American, 89% Medicaid recipients. Fifty-eight percent of families reported family-centered literacy orientation. The PPVT-III scores directly correlated with the number of AG visits with book given x number of books purchased (r2 = 0.025, p = 0.0006). Higher scores in EOWPVT-R were predicted by race and the number of visits with books given x number of books purchased (r2 = 0.182, p = 0.0009). All families reported reading together, half reporting positive family-centered literacy. Given the same number of books purchased for each child, the outcome scores were higher the greater the number of clinic visits wherein AG included early literacy and provision of books.

Head injury is the leading cause of fatality and long-term disability for children. Pediatric heads change rapidly in both size and shape during growth, especially for children under 3 years old (YO). To accurately assess the head injury risks for children, it is necessary to understand the geometry of the pediatric head and how morphologic features influence injury causation within the 0-3 YO population. In this study, head CT scans from fifty-six 0-3 YO children were used to develop a statistical model of pediatric skull geometry. Geometric features important for injury prediction, including skull size and shape, skull thickness and suture width, along with their variations among the sample population, were quantified through a series of image and statistical analyses. The size and shape of the pediatric skull change significantly with age and head circumference. The skull thickness and suture width vary with age, head circumference and location, which will have important effects on skull stiffness and injury prediction. The statistical geometry model developed in this study can provide a geometrical basis for future development of child anthropomorphic test devices and pediatric head finite element models.
Understanding the cultural and linguistic diversity of young children with hearing loss informs the provision of assessment, habilitation, and education services to both children and their families. Data describing communication mode, oral language use, and demographic characteristics were collected for 406 children with hearing loss and their caregivers when children were 3 years old. The data were from the Longitudinal Outcomes of Children with Hearing Impairment (LOCHI) study, a prospective, population-based study of children with hearing loss in Australia. The majority of the 406 children used spoken English at home; however, 28 other languages also were spoken. Compared with their caregivers, the children in this study used fewer spoken languages and had higher rates of oral monolingualism. Few children used a spoken language other than English in their early education environment. One quarter of the children used sign to communicate at home and/or in their early education environment. No associations between caregiver hearing status and children’s communication mode were identified. This exploratory investigation of the communication modes and languages used by young children with hearing loss and their caregivers provides an initial examination of the cultural and linguistic diversity and heritage language attrition of this population. The findings of this study have implications for the development of resources and the provision of early education services to the families of children with hearing loss, especially where the caregivers use a language that is not the lingua franca of their country of residence.

Few studies have investigated the outcomes and process of psychodynamic psychotherapies with children. Among the limited number of studies, some only paid attention to play and verbal production, as they are fundamental aspects in assessing the psychotherapy process. This paper focuses on an empirical investigation of a 3-year, once-a-week psychodynamic psychotherapy carried out with a 3-year-old girl. A process-outcome design was implemented to evaluate play and verbal discourse in in the initial, middle, and final parts of 30 psychotherapy sessions. Repeated measurements of standardized play categories (the Play Category System and the Affect in Play Scale—Preschool version) and verbal discourse (Verbal Production) were analyzed. To increase the clinical validity of the study, data from the assessment phase and vignettes from the sessions were reported to deepen the patient’s picture during the unfolding therapy process. Parent reports before and after the therapy were also included. Empirically measured changes in play and verbal production were fundamental in evaluating the young patient’s psychotherapy process. Verbal production and discourse ability progressively increased and took the place of play, which instead became more symbolic. Developmental issues as well as psychotherapy’s influence on the patient’s change, were discussed in relation to the role of play in enhancing the development of verbal dialog and the expression of the child’s emotions, needs, and desires.

Objective To examine associations between maternal and paternal use of corporal punishment (CP) for 3-year old children and intimate partner aggression or violence (IPAV) in a population-based sample. Methods The study sample (n = 1997) was derived from wave 3 of the Fragile Families and Child Well-being Study. Mother and father reports regarding their use of CP and their IPAV victimization were analyzed. IPAV included coercion, non-physical and physical aggression. Results About 65% of the children were spanked at least once in the prior month by one or both parents. Of those couples that reported any family aggression (87%), 54% reported that both CP and IPAV occurred. The most prevalent patterns of co-occurrence involved both parents as aggressors either toward each other (i.e., bilateral IPAV) or toward the child. The presence of bilateral IPAV essentially doubled the odds that one or both parents would use CP, even after controlling for potential confounders such as parenting stress, depression, and alcohol or other drug use. Of the five patterns of co-occurring family aggression assessed, the “single aggressor” model, in which only one parent aggressed in the family, received the least amount of empirical support. Conclusions Despite American Academy of Pediatrics’ recommendations against the use of CP, CP use remains common in the U.S. CP prevention and intervention efforts should carefully consider assumptions made about patterns of co-occurring aggression in families, given that adult victims of IPAV, including even minor, non-physical aggression between parents, have increased odds of using CP with their children.

Langerhans cell histiocytosis (LCH), previously known as histio-cytosis X, is a rare idiopathic disorder of reticulo-endothelial system with abnormal proliferation of bone marrow derived Langerhans cells along with a variable number of leukocytes, such as eosinophils, neutrophils, lymphocytes and plasma cells. Three years old male child presented with multifocal osteolytic lesions and papulosquamous skin lesions. Clinical and radio-graphic features, such as severe alveolar bone loss, mobility of teeth, precocious eruption of teeth, foating appearance of teeth in orthopantomogram (OPG), osteolytic lesion in skull and cutaneous lesions were highly suggestive of LCH disease. Skin biopsy confirmed a diagnosis of LCH. Induction chemotherapy with oral prednisolone and intravenous vinblastine was started. Child responded well to chemotherapy. The clinical significance of the presented case is to diagnose the case of LCH on the basis of the manifestation of severe periodontal disease as this can be first or only manifestation of LCH. A dentist plays a major role in the multidisciplinary treatment of LCH through routine examination and periodic follow-up.

Ascaris lumbricoides infection affects approximately 1.5 billion people globally. Children with environmental and socio-economic risk factors are more susceptible to infestation, with serious complications such as intestinal obstruction (IO), volvulus, intussusception, and intestinal necrosis.We present the case of a 3-year-old girl who arrived at emergency department with abdominal pain and diarrhea for the last 3 days. The previous day she took an unspecified anthelmintic. Symptoms worsened with vomiting and diarrhea, with expulsion of roundworms through mouth and anus. Physical examination revealed bloating, absence of bowel sounds, abdominal tenderness, and a palpable mass in right hemi-abdomen. Abdominal radiographs showed air-fluid levels with mild bowel distention and shadows of roundworms. The diagnosis of IO by A lumbricoides. infestation was established and surgical approach scheduled. During exploratory laparotomy an intraluminal bolus of roundworms from jejunum to ascendant colon was evident. An ileum enterotomy was performed and worms were removed. Fluid therapy and antibiotics for 72 hours were administered, with posterior albendazol treatment for 3 days. Patient was uneventfully discharged on the tenth day.Reduction in parasitic load by means of improvements in sanitation, health education, and anthelmintic treatment must be implemented in endemic zones to prevent serious life-threatening complications by A lumbricoides. infestation, because some of them require urgent surgical treatment.

Thirteen monolingual Mandarin-speaking children residing in the U.S. were recruited to examine their production of the four Mandarin lexical tones in monosyllabic words. A picture-naming task was used to elicit the children's productions of lexical tones in isolated words and in sentence final position. Four mothers were asked to say the same set of words to their children in a picture reading activity. The children's and the mothers' productions were recorded and low-pass filtered at 500 and 400 Hz, respectively, to eliminate phonemic and semantic information. Ten Mandarin-speaking judges were recruited to identify the children's and adults' tone productions from the filtered stimuli. Contrary to the findings of L1 research conducted in countries where Mandarin is the language of the environment, the present results revealed that the lexical tones produced by 3-year-old children acquiring Mandarin as their first language in the U.S. were not yet adultlike. Children's tone productions were more difficult to categorize than the mothers' productions. The judges had significantly more difficulty identifying children's dipping tones than the children's level tones, rising tones, or falling tones, suggesting that the dipping tone posed the most difficulties for the children.

Just like other face dimensions, age influences the way faces are processed by adults as well as by children. However, it remains unclear under what conditions exactly such influence occurs at both ages, in that there is some mixed evidence concerning the presence of a systematic processing advantage for peer faces (own-age bias) across the lifespan. Inconsistency in the results may stem from the fact that the individual's face representation adapts to represent the most predominant age traits of the faces present in the environment, which is reflective of the individual's specific living conditions and social experience. In the current study we investigated the processing of younger and older adult faces in two groups of adults (Experiment 1) and two groups of 3-year-old children (Experiment 2) who accumulated different amounts of experience with elderly people. Contact with elderly adults influenced the extent to which both adult and child participants showed greater discrimination abilities and stronger sensitivity to configural/featural cues in younger versus older adult faces, as measured by the size of the inversion effect. In children, the size of the inversion effect for older adult faces was also significantly correlated with the amount of contact with elderly people. These results show that, in both adults and children, visual experience with older adult faces can tune perceptual processing strategies to the point of abolishing the discrimination disadvantage that participants typically manifest for those faces in comparison to younger adult faces.

A 3-year-old female gerbil developed a non-healing skin wound due to a malignant neoplasm. Histology, immunohistochemistry (cytokeratin 19 positive; vimentin, estrogen, and progesterone receptor negative), and electron microscopy (no desmosomes or melanosomes) revealed an undifferentiated carcinoma with pulmonary metastasis. Unlike in previous reports, it did not arise from the abdominal pad’s sebaceous gland. PMID:26740704

Poor motor skills and differences in sensory processing have been noted as behavioral markers of common neurodevelopmental disorders. A total of 171 healthy children (81 girls, 90 boys) were investigated at age 3 to examine relations between temperament, sensory processing, and motor coordination. Using the Japanese versions of the Children's Behavior Questionnaire (CBQ), the Sensory Profile (SP-J), and the Little Developmental Coordination Disorder Questionnaire (LDCDQ), this study examines an expanded model based on Rothbart's three-factor temperamental theory (surgency, negative affect, effortful control) through covariance structure analysis. The results indicate that effortful control affects both sensory processing and motor coordination. The subscale of the LDCDQ, control during movement, is also influenced by surgency, while temperamental negative affect and surgency each have an effect on subscales of the SP-J.

Food allergy may constitute a major burden to children and their families. A 3-year-old girl was intolerant to milk, sugar, egg white, pork meat, and other foods, causing eczema and dyspnoe. She was treated with Nambudripad's Allergy Elimnation Technique (NAET), a combination of kinesiology and acupressure. After 7 treatment sessions (within 4 weeks) she was free of symptoms. After three years, she can still eat everything without symptoms. This case report highlights the possible benefit of NAET for children with food allergy. Randomized clinical trials should be encouraged to study the effectiveness of NAET in treating food allergy.

Valproic acid (VPA) is considered to be a drug of first choice for the therapy of generalized and focal epilepsies, including special epileptic syndromes. The drug is usually well tolerated, rare serious complications may occur in some patients, including hemorrhagic pancreatitis, coagulapathies, bone marrow suppression, VPA-induced hepatotoxicity and encephalopathy. We report a case of VPA-associated encephalopathy without hyperammonemia in a 3-year-old girl with Pallister-Killian-Syndrom, combined with a mild hepatopathy and thrombopathy. After withdrawal of VPA, the clinical symptoms and the electroencephalography-alterations vanished rapidly.

This study examined which body part labels children could (i) produce when the experimenter touched different locations on her own body, asking each time 'What's this?' and (ii) comprehend by touching the correct locations on their own bodies in response to the experimenter asking 'Where's the [body-part label]?'. Seventeen children aged between 26 and 41 months, tested in a repeated measures procedure, were presented with 50 different body part stimuli in 200 test trials per child. Overall, the children produced fewer body part labels than they could comprehend. The accuracy of children's responses depended on (i) the location or extent of each body part (facial and broad body features were better known; joints and features in or attached to broad body parts the least well known); (ii) the amount of sensory (but not motor) representation each body part has in the human cortex; and (iii) whether a body part was commonly named by caregivers. These results present a precise mapping of the body parts that young children are able to name and locate on their own bodies in response to body part names; they suggest several possible determinants of lexical-semantic body knowledge and add to the understanding of how it develops in childhood.

Young children can in principle make generic inferences (e.g., "doffels are magnetic") on the basis of their own individual experience. Recent evidence, however, shows that by 4 years of age children make strong generic inferences on the basis of a single pedagogical demonstration with an individual (e.g., an adult demonstrates for the child that a single "doffel" is magnetic). In the current experiments, we extended this to look at younger children, investigating how the mechanisms underlying this phenomenon are integrated with other aspects of inductive inference during early development. We found that both 2- and 3-year-olds used pedagogical cues to guide such generic inferences, but only so long as the "doffel" was linguistically labeled. In a follow-up study, 3-year-olds, but not 2-year-olds, continued to make this generic inference even if the word "doffel" was uttered incidentally and non-referentially in a context preceding the pedagogical demonstration, thereby simply marking the opportunity to learn about a culturally important category. By 3 years of age, then, young children show a remarkable ability to flexibly combine different sources of culturally relevant information (e.g., linguistic labeling, pedagogy) to make the kinds of generic inferences so central in human cultural learning.

For 3-year-old children suitable methods to estimate body composition are sparse. We aimed to develop predictive equations for estimating fat-free mass (FFM) from bioelectrical impedance (BIA) and anthropometry using dual-energy X-ray absorptiometry (DXA) as reference method using data from 99 healthy 3-year-old Danish children. Predictive equations were derived from two multiple linear regression models, a comprehensive model (height(2)/resistance (RI), six anthropometric measurements) and a simple model (RI, height, weight). Their uncertainty was quantified by means of 10-fold cross-validation approach. Prediction error of FFM was 3.0% for both equations (root mean square error: 360 and 356 g, respectively). The derived equations produced BIA-based prediction of FFM and FM near DXA scan results. We suggest that the predictive equations can be applied in similar population samples aged 2-4 years. The derived equations may prove useful for studies linking body composition to early risk factors and early onset of obesity.

This study examined the relationship of child gender and maternal race to the looking and talking interactions of fifty-four 3-year-old prematurely born children and their mothers. More gender differences occurred for looking than for talking, whereas racial differences were stronger for talking than for looking. Transitional probabilities between looking situations suggested that gender differences occurred because girls were more likely to respond when their mothers were looking at them than were boys. Transitional probabilities between talking situations suggested that racial differences occurred because non-White mothers (African Americans and Native Americans in this study) were less likely to respond when their children were talking to them than were White mothers. The only significant interaction of gender by race was with White mothers who were more likely to respond when their girls were talking. When analyses were repeated, controlling for the effects of intelligence quotient, gestational age, neurobiologic risk score, and socioeconomic status (SES), gender differences for looking situations became smaller, whereas racial differences for talking situations became larger. Gender and ethnicity differences for looking and talking interactions cannot be explained by simple differences in health status or SES. These differences may possibly be related to the differential brain functions and hormonal effects of boys and girls, as well as to differential socialization that influences gender identity and gender roles. They also may be related to the higher incidence of language delays in non-White children and to differences in sociocultural norms and parenting between White and non-White mothers.

Children are exposed to highly variable input from multiple sources within their speech community. This study examines the acquisition of allophones in Spanish and French by monolingual and bilingual children. We hypothesised that two factors would influence allophone acquisition: (1) the amount of exposure to phonological input, and (2) the degree of variability of the allophonic pattern. Thirty-four typically developing 3-year-old participated in the study. The analyses revealed that regardless of the language, the monolingual children produced similar error rates in the production of the target allophones. In contrast, the bilingual children produced different patterns of acquisition of the allophones: the Spanish-English bilinguals produced higher error rates than the monolinguals, whereas the French-English bilinguals produced lower error rates than the monolinguals. Possibilities for these differences are discussed within the context of structural complexity as well as in light of the effects of between-language interaction on bilingual phonological development.

A 3-year-old male patient was referred to the Maxillofacial Surgery Clinic due to a painless swelling of the right palatal region. Conventional radiographs revealed no alteration of the dentition and did not delineate a lesion in the region of interest. Cone-beam tomography depicted small radiopaque, extraosseous deposits inside the palatal space. Histological examination revealed a minute mixed epithelial-mesenchymal lesion of odontogenic origin. We made the diagnosis of a peripheral developing odontoma, taking into consideration the components and arrangements of structures of the lesion. Early intervention is advisable to prevent these odontogenic lesions from eventually deforming the jaw and displacing adjacent teeth. Cone-beam tomography was a valuable pre-operative diagnostic tool to assess the lesion as being composed in part of hard tissue.

Twenty children, ten 2-year-olds and ten 3-year-olds, participated in an AB procedure. In the baseline phase, each child was trained the same four matching relations to criterion under intermittent reinforcement. During the subsequent imitation test, the experimenter modeled a total of 20 target gestures (six trials each) interspersed with intermittently reinforced baseline trials. In each session, target gestures were selected in a pre-randomized sequence from: Set 1—ear touches; Set 2—shoulder touches; Set 3—midarm touches; and Set 4—wrist touches; subjects' responses to targets were not reinforced. In each target set, half the gestures featured in nursery matching games and were termed common targets whereas the remainder, which were topographically similar but did not feature in the games, served as uncommon targets. The children produced significantly more matching responses to common target models than to uncommon ones. Common responses were also produced as mismatches to uncommon target models more often than vice versa. Response accuracy did not improve over trials, suggesting that "parity" did not serve as a conditioned reinforcer. All children showed a strong bias for "mirroring"—responding in the same hemispace as the modeler. The 2-year-olds produced more matching errors than the 3-year-olds and most children showed a bias for responding with their right hands. The strong effects of training environment (nursery matching games) are consistent with a Skinnerian account, but not a cognitive goal theory account, of imitation in young children. PMID:18422018

Constructivist views of cognitive development often converge on 2 key points: (a) the child's goal is to build large conceptual structures for understanding the world, and (b) the child plays an active role in developing these structures. While previous research has demonstrated that young children show a precocious capacity for concept and theory building when they are provided with helpful data within training settings, and that they explore their environment in ways that may promote learning, it remains an open question whether young children are able to build larger conceptual structures using self-generated evidence, a form of active learning. In the current study, we examined whether children can learn high-order generalizations (which form the basis for larger conceptual structures) through free play, and whether they can do so as effectively as when provided with relevant data. Results with 2- and 3-year-old children over 4 experiments indicate robust learning through free play, and generalization performance was comparable between free play and didactic conditions. Therefore, young children's self-directed learning supports the development of higher-order generalizations, laying the foundation for building larger conceptual structures and intuitive theories.

Ameloblastic fibro-odontoma (AFO) predominantly occurs in the jaw bones of children and young adults. Extraosseous AFO is extremely rare. We describe a peripheral ameloblastic fibro-odontoma in the maxillary gingiva of a 3-year-old girl. The clinical appearance resembled fiery red reactive gingival lesions. The histopathological examination of the excised lesion showed small islands and cords of odontogenic epithelium with cellular myxoid stroma in the subepithelial tissue. The mass contained calcified material and an enamel-like deposit. Many small blood vessels appeared in the connective tissue surrounding the odontogenic epithelium. The immunohistochemical assays showed strong reactivity for amelogenin, β-catenin, CD44, and CD31 in the tissue sections. There was no recurrence after the 1-year follow-up. Because this lesion clinically resembles other nonneoplastic lesions and is very rare in gingiva, establishing a correct diagnosis is achieved only based on specific histological characteristics. Conservative excision of the tumor is the treatment of choice. PMID:25161776

The present cohort study examined how lifestyle, household environment, and caries activity test score of Japanese children at age 1.5 years affected their dental caries incidence at age 3. Inclusion criteria were 1.5-year-old children with no dental caries. Dental examinations were performed for 33,655 children who participated in routine dental examinations at 1.5 years of age, and the exam was repeated approximately 21 months later (at age 3) at the Kobe City Public Health Center in Japan. After excluding 622 children who had caries at age 1.5 and 1831 children with missing lifestyle and household environment data in the questionnaires, the final data analysis was performed on a total of 31,202 children (16,052 boys, 15,150 girls).The multivariate logistic regression analysis indicated a strong association of the consumption of sugar-sweetened beverages/snacks, less frequent tooth brushing by the parents, lack of fluoride varnish, family history of smoking, with the risk of developing dental caries. A child's late bedtime is also one of the major risk factors for dental caries development. Further investigation is needed to examine whether the short duration or the irregularity of the sleep-wake cycle would affect early childhood oral health and whether there is a relationship between late bedtime and late night snack intake.

In the risk assessment of chemical substances, aggregation of exposure to a substance from different sources via different pathways is not common practice. Focusing the exposure assessment on a substance from a single source can lead to a significant underestimation of the risk. To gain more insight on how to perform an aggregate exposure assessment, we applied a deterministic (tier 1) and a person-oriented probabilistic approach (tier 2) for exposure to the four most common parabens through personal care products in children between 0 and 3 years old. Following a deterministic approach, a worst-case exposure estimate is calculated for methyl-, ethyl-, propyl- and butylparaben. As an illustration for risk assessment, Margins of Exposure (MoE) are calculated. These are 991 and 4966 for methyl- and ethylparaben, and 8 and 10 for propyl- and butylparaben, respectively. In tier 2, more detailed information on product use has been obtained from a small survey on product use of consumers. A probabilistic exposure assessment is performed to estimate the variability and uncertainty of exposure in a population. Results show that the internal exposure for each paraben is below the level determined in tier 1. However, for propyl- and butylparaben, the percentile of the population with an exposure probability above the assumed "safe" MoE of 100, is 13% and 7%, respectively. In conclusion, a tier 1 approach can be performed using simple equations and default point estimates, and serves as a starting point for exposure and risk assessment. If refinement is warranted, the more data demanding person-oriented probabilistic approach should be used. This probabilistic approach results in a more realistic exposure estimate, including the uncertainty, and allows determining the main drivers of exposure. Furthermore, it allows to estimate the percentage of the population for which the exposure is likely to be above a specific value.

The present study investigated 3-year-old children’s learning processes about object functions. We built on children’s tendency to commit scale errors with tools to explore whether they would selectively endorse object functions from a linguistic in-group over an out-group model. Participants (n = 37) were presented with different object sets, and a model speaking either in their native or a foreign language demonstrated how to use the presented tools. In the test phase, children received the object sets with two modifications: the original tool was replaced by one that was too big to achieve the goal but was otherwise identical, and another tool was added to the set that looked different but was appropriately scaled for goal attainment. Children in the Native language condition were significantly more likely to commit scale errors – that is, choose the over-sized tool – than children in the Foreign language condition (48 vs. 30%). We propose that these results provide insight into the characteristics of human-specific learning processes by showing that children are more likely to generalize object functions to a category of artifacts following a demonstration from an in-group member.

A series of three experiments explored the relationship between 3-year-old children's ability to name target body parts and their untrained matching of target hand-to-body touches. Nine participants, 3 per experiment, were presented with repeated generalized imitation tests in a multiple-baseline procedure, interspersed with step-by-step training that enabled them to (i) tact the target locations on their own and the experimenter's bodies or (ii) respond accurately as listeners to the experimenter's tacts of the target locations. Prompts for on-task naming of target body parts were also provided later in the procedure. In Experiment 1, only tact training followed by listener probes were conducted; in Experiment 2, tacting was trained first and listener behavior second, whereas in Experiment 3 listener training preceded tact training. Both tact and listener training resulted in emergence of naming together with significant and large improvements in the children's matching performances; this was true for each child and across most target gestures. The present series of experiments provides evidence that naming--the most basic form of self-instructional behavior--may be one means of establishing untrained matching as measured in generalized imitation tests. This demonstration has a bearing on our interpretation of imitation reported in the behavior analytic, cognitive developmental, and comparative literature.

In this manuscript, we analyse the attitudes and practices of Estonian parents (N = 198) who allowed their 0-3-year olds to use smart devices. We aimed to discover if there was an interaction between parental use of smart technologies, parents' attitudes and the child's age that would predict young children's usage of smart devices. We also wanted…

Recurrent parotitis is a non-obstructive, non-suppurative inflammatory disease which is characterized by unilateral or bilateral parotid gland swelling attacks. It is also known as juvenile recurrent parotitis. Although the etiology is unknown, congenital malformations of the ductus, genetic predisposition, infections, allergies, autoimmune diseases, and some immune deficiencies are blamed. Here, we present a case report of recurrent parotitis with selective immunoglobulin A deficiency in a six-year-old boy. The patient was presented to us with a new episode of swelling of left parotid region. In the last 2 years, the patient suffered from recurrent parotitis which lasted for approximately 5 days in ten individual episodes. PMID:24883201

Previous research has shown an association between children’s development of psychosocial and motor skills. This study evaluated the development of these skills in 301 three-year-old deaf and hard of hearing children (M: 37.8 months) and considered a range of possible predictors including gender, birth weight, age at first fitting with hearing devices, hearing device used, presence of additional disabilities, severity of hearing loss, maternal education, socio-economic status (SES), language ability, and communication mode. Caregivers reported on children’s development using the Child Development Inventory (CDI). On average, both psychosocial and motor development quotients were within the typical range for hearing children, with large individual differences. There was a positive correlation between language ability and both social and motor development, and also between social and motor development. Age at first fitting of hearing aids (as an indicator of age at identification of hearing loss), SES, degree of hearing loss, and maternal education were not significant predictors of social skill or motor development, whereas presence of additional disabilities and birth weight were. Girls performed better than boys on all but the Gross Motor subscale of the CDI. Children with hearing aids tended to perform better than those with cochlear implants on the Gross Motor subscale.

Urticaria with angioedema is a common clinical presentation that often poses a challenge for allergists. The differential diagnosis for urticaria is broad, making the evaluation and pinpointing the underlying cause difficult and frustrating for both families and physicians. Certain causes of urticaria such as infections or medications are more common and easier to identify whereas less frequently seen conditions are often overlooked because of their rarity. One such condition is mastocytosis. Mastocytosis is a rare disease that very seldom presents with urticaria but may be associated with significant morbidity and mortality if not recognized in a timely manner. We are presenting a case of a 14-year-old boy who presented with urticaria and angioedema possibly caused by a solitary mastocytoma. The learning points from this case are that mastocytosis should be considered in the differential diagnosis of urticaria and solitary mastocytomas may remain active into adolescence, raising concern for systemic progression.

The coexistence of Bacillus Calmette-Guérin (BCG)-induced lupus vulgaris involving the site of vaccination with lichen scrofulosorum is rare. Herein we report a 3-year-old boy who presented with lupus vulgaris at the vaccination site 3 weeks after neonatal BCG vaccination followed by the development of lichen scrofulosorum approximately 2.5 years later. Characteristic clinical morphology, typical histopathology, and positive DNA polymerase chain reaction for Mycobacterium bovis confirmed the clinical diagnosis.

The present study investigates the relationship between mother-child interaction styles with 19 months and children's autobiographical memory with 3 years of age in two cultural contexts: New Delhi, India (n = 25) and Berlin, Germany (n = 33). Results demonstrate similarities as well as culture specificities. In both contexts, maternal elaborations during reminiscing were related to children's memory contributions. Over time, maternal support for toddlers' self-expression during free play at 19 months predicted their children's memory elaborations at 3 years in the Berlin context. In the Delhi context, toddlers' willingness to carry out their mothers' requests at 19 months predicted their memory elaborations at 3 years. These results suggest different motivational bases underlying children's autobiographical memory contributions during mother-child reminiscing related to different cultural orientations.

In our previous study of 3-year-old children in a dioxin contamination hot spot in Vietnam, the high total dioxin toxic equivalent (TEQ-PCDDs/Fs)-exposed group during the perinatal period displayed lower Bayley III neurodevelopmental scores, whereas the high 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD)-exposed group displayed increased autistic traits. In autistic children, urinary amino acid profiles have revealed metabolic alterations in the amino acids that serve as neurotransmitters in the developing brain. Therefore, our present study aimed to investigate the use of alterations in urinary amino acid excretion as biomarkers of dioxin exposure-induced neurodevelopmental deficits in highly exposed 3-year-old children in Vietnam. A nested case-control study of urinary analyses was performed for 26 children who were selected from 111 3-year-old children whose perinatal dioxin exposure levels and neurodevelopmental status were examined in follow-up surveys conducted in a dioxin contaminated hot spot. We compared urinary amino acid levels between the following 4 groups: (1) a high TEQ-PCDDs/Fs and high TCDD-exposed group; (2) a high TEQ-PCDDs/Fs but low TCDD-exposed group; (3) a low TEQ-PCDDs/Fs exposed and poorly developed group; and (4) a low TEQ-PCDDs/Fs exposed and well-developed group. Urinary levels of histidine and tryptophan were significantly decreased in the high TEQ-PCDDs/Fs and high TCDD group, as well as in the high TEQ-PCDDs/Fs but low TCDD group, compared with the low TEQ-PCDDs/Fs and well-developed group. However, the ratio of histidine to glycine was significantly lower only in the high TEQ-PCDDs/Fs and high TCDD group. Furthermore, urinary histidine levels and the ratio of histidine to glycine were significantly correlated with neurodevelopmental scores, particularly for language and fine motor skills. These results indicate that urinary histidine is specifically associated with dioxin exposure-induced neurodevelopmental deficits, suggesting that

Leeches (phylum: Annelida, class: hirudinea) could infest wide range of livestock such as cow, buffalo, sheep, goat, horse, mule, ass, dog, pig and even human. In November 2013, a 3-year old jackass from Dehloran county, Ilam province, Iran, was infected through his mouth due to drinking spring water. Symptoms including stress, anxiety and tachycardia were seen. After examining oral cavity of jackass, a leech was observed in upper gum. The leech was measured after separation which was three inches in length. The leech was adult which has dark green with orange lines, and it was identified as Limnatis nilotica species. It seems that using spring, subterranean water, pond etc. is the main causes of livestock infestation with leech. Ranchers could be recommended to decontaminate leech waters to prevent further leech infestation cases.

This study examined 3-year-olds' explanations for actions of theirs that were premised on a false belief. In Experiment 1, children stated what they thought was inside a crayon box. After stating "crayons," they went to retrieve some paper to draw on. Children were then shown that the box contained candles and were asked to (a) state their initial belief and (b) explain their action of getting paper. Children who were unable to retrieve their false belief were unable to correctly explain their action. Experiments 2 and 3 ruled out several alternative interpretations for these findings. In Experiment 4, children planned and acted on their false belief. Again, children who were unable to retrieve their false belief were unable to correctly explain their action.

A 12-year-old boy was referred to the surgical unit with 4 h history of severe lower abdominal pain and bilious vomiting. No other symptoms were reported and there was no significant medical or family history. Examination revealed tenderness in the lower abdomen, in particular the left iliac fossa. His white cell count was elevated at 19.6×10(9)/L, with a predominant neutrophilia of 15.8×10(9)/L and a C reactive protein of <0.3 mg/L. An abdominal X-ray revealed intraperitoneal gas and a chest X-ray identified free air under both hemidiaphragms. Subsequent diagnostic laparoscopy identified a perforated duodenal ulcer that was repaired by means of an omental patch. The case illustrates that although uncommon, alternate diagnoses must be borne in mind in children presenting with lower abdominal pain and diagnostic laparoscopy is a useful tool in children with visceral perforation as it avoids treatment delays and exposure to excess radiation.

Dysosteosclerosis (DSS), an extremely rare dense bone disease, features short stature and fractures and sometimes optic atrophy, cranial nerve palsy, developmental delay, and failure of tooth eruption in infancy or early childhood consistent with osteopetrosis (OPT). Bone histology during childhood shows unresorbed primary spongiosa from deficient osteoclast action. Additionally, there is remarkable progressive flattening of all vertebrae and, by adolescence, paradoxical metaphyseal osteopenia with thin cortical bone. Reports of consanguinity indicate autosomal recessive inheritance, yet more affected males than females suggest X-linked recessive inheritance. We investigated a nonconsanguineous girl with DSS. Osteosclerosis was discovered at age 7 months. Our studies, spanning ages 11 to 44 months, showed weight at approximately 50th percentile, and length diminishing from approximately 30th percentile to –2.3 SD. Head circumference was +4 SD. The patient had frontal bossing, blue sclera, normal teeth, genu valgum, and unremarkable joints. Radiographs showed orbital and facial sclerosis, basilar thickening, bone-in-bone appearance of the pelvis, sclerotic long bone ends, and fractures of ribs and extremities. Progressive metaphyseal widening occurred as vertebrae changed from ovoid to flattened and became beaked anteriorly. A hemogram was normal. Consistent with OPT, serum parathyroid hormone (PTH) concentrations reflected dietary calcium levels. Serum bone alkaline phosphatase, osteocalcin, and TRACP-5b were subnormal. The iliac crest contained excessive primary spongiosa and no osteoclasts. No mutations were identified in the splice sites or exons for the genes encoding chloride channel 7, T-cell immune regulator 1, OPT-associated transmembrane protein 1, and monocyte colony-stimulating factor (M-CSF) and its receptor C-FMS, ANKH, OPG, RANK, and RANKL. Genomic copy-number microarray was unrevealing. Hence, DSS is a distinctive OPT of unknown etiology featuring osteoclast deficiency during early childhood. How osteopenia follows is an enigma of human skeletal pathobiology. © 2010 American Society for Bone and Mineral Research. PMID:20499338

Habit tic nail deformity is a nail dystrophy resulting from habitual, repetitive trauma to the nail. It is usually acquired in adulthood, however, we report a case of habit tic nail deformity in an 8 year old boy. The diagnosis was made clinically with further history revealing that the boy repeatedly rubbed his thumbnails and pushed the cuticles. Emollient cream (Balneum®) was recommended twice daily and both the patient and his mother were educated on the behavioral nature of this condition. There was marked improvement at 6 months of treatment and further improvement at 12 months.We note that habit tic nail deformity is not exclusive to adults. Diagnosis can be made clinically. History and physical examination provide valuable clues and psychosocial links must be explored and addressed. Management is challenging and compliance with treatment is variable. Patient education, barrier methods, and behavioral therapy can be helpful in preventing further trauma to the nails.

Mentalistic and behavioral analyses of noncompliance among children with hyperactive behavior are contrasted. Then, a behavioral training program for 3 boys with behavior characteristic of attention deficit hyperactivity disorder and oppositional defiant disorder is described. The child-focused training was conducted in conjunction with parent training. In an effort to increase the rate of compliance, the child-training program was designed to alter the function of parent commands by teaching the boys to verbalize rules about parent commands and consequences in the context of observing parent—child role-plays. Training was conducted within a multiple baseline design across children. Direct observation of mother—child interactions, telephone interviews, and standardized rating scales showed that training resulted in clinically significant reductions in noncompliance and improved parenting behavior. A 6-month follow-up revealed stable outcomes. PMID:22477227

Cystic structures within the pericardial cavity are rare. They are divided into epicardial and pericardial variants. Pericardial and epicardial cysts rarely cause symptoms. This report describes a case of epicardial cyst with acute cardiac tamponade in a 2-year-old boy with no previous cardiac history who was transferred to our hospital because of hemodynamic instability. Emergency drainage of the pericardial effusion and complete excision of the cyst were performed through a median full sternotomy.

The purpose of this study was to describe the present status of geography education in boys' intermediate schools in Riyadh, Saudi Arabia as perceived by geography teachers and supervisors; that is, to investigate the objectives, content, methods of teaching, tools and resources that are available and used in classrooms, evaluation techniques, and problems encountered in the teaching of geography. To collect data from this representative sample population, a questionnaire was developed by the researcher specifically for this study. Questionnaire data was collected from 19 social studies supervisors and 213 geography teachers. Percentages, frequencies, means, and standard deviations were computed for each questionnaire item. Chi Square tests were applied to determine if any significant differences could be identified between the observed and expected responses of supervisors and teachers. Major findings of the study indicated that both supervisors and teachers tend to strongly support the identified geography objectives. Most teachers and supervisors also indicated that the current geography curriculum contains enough information about Saudi Arabia, the Arabic world, and the Islamic world. In addition, the also indicated that geography content promotes a sense of patriotism and cultural pride. Responses indicated that educators see deficiencies in the content: it does not focus sufficiently on current events nor on developing student skills such as research and technical skills like drawing maps. Lecture and discussion are the most commonly used strategies in the teaching of geography. Field trips, role-playing, scientific competitions, scientific games, solving problems, and individual learning are less commonly used. Teaching tools most commonly used are wall maps and earth globes, whereas the use of geographical transparencies, models, and instruments is not common. Most of the teachers do lot use computers in their teaching. Evaluation techniques depend

This study investigates aspects of voice onset time (VOT) of voiceless bilabial and velar stops in monolingual and bilingual children. VOT poses a special challenge for bilingual Spanish- and English-speaking children because although this VOT distinction exists in both languages, the values differ for the same contrast across Spanish and English. Twenty-four 3-year-olds participated in this study (8 bilingual Spanish–English, 8 monolingual Spanish and 8 monolingual English). The VOT productions of /p/ and /k/ in syllable-initial stressed singleton position were compared across participants. Non-parametric statistical analyses were performed to examine differences (1) between monolinguals and bilinguals and (2) between English and Spanish. The main findings of the study were that monolingual and bilingual children generally differed on VOT in English, but not in Spanish. No statistically significant differences were found between the Spanish and the English VOT of the bilingual children, but the VOT values did differ significantly for monolingual Spanish-versus monolingual English-speaking participants. Our findings were interpreted in terms of Flege’s Speech Learning Model, finding possible evidence for equivalence classification. PMID:21787142

The upper and lower intercanine arch widths and the prevalence of posterior crossbite were registered for 445 3-year-old children with and without a continuing or previous dummy-sucking or finger-sucking habit in different areas in Sweden and Norway. Sami children from northern Norway also took part in the study, as well as 15 medieval skulls with intact deciduous dentitions. Compared with the nonsuckers, an increased prevalence of posterior crossbite was observed for the finger suckers, especially the Swedish girls. Stepwise logistic regression showed that posterior crossbite could be predicted with upper intercanine arch width alone. The finger sucking variable would not improve prediction; neither did other entities such as cohort (residental area), sex, lower intercanine arch width, nor the difference between upper and lower intercanine arch width. High prevalences of posterior crossbite were registered for dummy suckers (pacifiers) especially the Swedish girls (26%). Stepwise logistic regression showed that posterior crossbite in dummy suckers could be predicted with upper and lower intercanine arch width. Stepwise linear regression showed that both arches tended to be narrower in Swedes and girls, and that dummy sucking decreased the upper and increased the lower intercanine arch width. Analyses of covariance revealed that at least 2 years of dummy sucking is necessary to produce a significant effect in the upper jaw and 3 years in the lower jaw.

Cooperation can be maintained if individuals reciprocate favors over repeated interactions. However, it is not known when during development the psychological capacities to engage in contingent reciprocation emerge. Therefore, we tested when children begin to differentiate between reciprocal and nonreciprocal interactions in their resource sharing. We compared the sharing behavior of 3- and 5-year-olds in two situations. In an experimental condition, the child and a puppet partner alternated the roles of donor and recipient. In a control condition, the puppet had no opportunity to reciprocate. Results showed that 5-year-olds, but not 3-year-olds, increased their sharing toward a potential reciprocator. In addition, we found that children's ability to delay gratification was positively related to their tendency to share in both conditions. These findings show that reciprocity in anticipation of repeated interactions emerges during middle childhood. Moreover, our results highlight the importance of the ability to delay gratification as a prerequisite for children's sharing. We discuss how children's emerging cognitive abilities enable reciprocal sharing in situations where a child must react to or anticipate a partner's behavior.

Nutritional status of children is commonly assessed by anthropometry both in under and overnutrition. The link between anthropometry and body fat, the body compartment most affected by overnutrition, is well known, but the link with muscle mass, the body compartment most depleted in undernutrition, associated with infections, remains unknown. In this study, we examined the relationship between common anthropometric indices and body composition measured by dual-energy X-ray absorptiometry (DEXA) in a sample of 121 healthy 3-year-old Danish children. Appendicular (arms and legs) lean mass was used to estimate muscle mass. Overall, anthropometric measures were more effective to measure absolute size of fat, lean and muscle mass than their relative sizes. Proportion of the variance explained by anthropometry was 79% for lean mass, 76% for fat mass and 74% for muscle mass. For fat mass and lean mass expressed as percentage of total body mass, this proportion was 51% and 66%, respectively; and for muscle mass as percentage of lean mass it was 34%. All the best reduced multivariate models included weight, skinfold and gender except the model estimating the proportion of muscle mass in lean body mass, which included only mid-upper arm circumference and subscapular skinfold. The power of height in the weight-to-height ratio to determine fat mass proportion was 1.71 with a 95% confidence interval (0.83-2.60) including the value of 2 used in body mass index (BMI). Limitations of anthropometry to assess body composition, and especially for muscle mass as a proportion of lean mass, should be acknowledged.

OBJECTIVES Describe the association between the purchase price of Thoroughbred yearlings sold in Australia and racing performance as 2- and 3-year-olds. METHODS Race performance data of 2773 Thoroughbred yearlings sold at auction during 2003 were collected. Associations between purchase price and the probability of starting, the number of race starts and the prize money earned were examined. RESULTS In total, 2206 (79.6%) horses started a race. The mean number of race starts was six and the mean prize money earned was A$24,420. A total of 1711 (61.5%) horses earned prize money, 402 (14.4%) earned more than their purchase price, 312 (11.2%) earned more than A$40,000, the estimated cost of training, and 142 (5.1%) earned A$40,000 more than their purchase price. There was a positive association between purchase price category and the probability of starting, number of starts, earning prize money and earning greater than A$40,000 (P < 0.001). Purchase price category was negatively associated with the probability of earning greater than the purchase price (P < 0.001). The proportion of horses earning greater than the purchase price plus $40,000 was significantly different (P = 0.03) among the five price categories. CONCLUSION Yearling purchase price was positively associated with all race performance outcomes measured and researchers examining the race performance of yearlings purchased at sales should consider including purchase price when modelling. The Thoroughbred yearling market in Australia behaves in a similar manner to the United States market; owners pay a premium to enter the sport of racing and an additional premium in the quest to own a champion.

Tuberculosis (TB) is a common disease worldwide that is caused by Mycobacterium tuberculosis. Tuberculosis of the spine, also called Pott disease, is the most common site of bony dissemination. Although children are disproportionately affected, spinal TB is nonetheless rare in very young children. Cases involving infants requiring surgical intervention have been previously reported, and they are often associated with greater management challenges given the technical difficulty with instrumentation in very young children. This case involved a 3-year-old girl with TB centered at T-6, who presented with myelopathy from spinal cord compression and a severe kyphotic deformity (> 60°). She underwent a single-stage costotransversectomy for vertebral column resection, followed by reconstruction with an anterior expandable titanium cage and posterior pedicle screw instrumentation. At last follow-up, the patient was clinically and radiographically stable. The authors report on the youngest patient with spinal TB treated surgically with this strategy and review the literature regarding prior cases involving young children. Although limited by the paucity of cases in the literature, surgical debridement and spinal fusion appear to provide a safe alternative to prolonged bed rest or casting and may offer additional benefits of a faster recovery and ambulation.

The Children's Eating Behaviour Questionnaire (CEBQ) was developed to measure eating behaviors related to obesity risk in children. However, this questionnaire has not been validated for use in South East Asia, where parenting practices are different from those in western countries and child obesity rates are increasing. The aim of this study was to examine the validity of the CEBQ administered to mothers of children aged 3 years in Singapore. Confirmatory factor analysis (CFA) was used to examine if the original 35-item, 8-factor model was supported in our cohort. Participants were 636 mother-child dyads (mean (SD) child age = 36.7 (1.6) months), from the Growing Up in Singapore Towards healthy Outcomes (GUSTO) birth cohort in which the mothers were characterized in pregnancy and children were followed up to age 3 years. The CFA showed a poor model fit; RMSEA = 0.072 (PCLOSE<0.001), SRMR = 0.094, CFI = 0.826, and TLI = 0.805. Exploratory factor analysis revealed a 35 item, 7-factor structure (factor loadings ≥ 0.35): enjoyment of food, food fussiness, emotional overeating, desire to drink, emotional under eating, satiety responsiveness and slowness in eating. Cronbach's alpha estimates ranged from 0.70 to 0.88 for the 7 subscales. Convergent validity tests via correlation analysis revealed that emotional under eating (r = -0.14), slowness in eating (r = -0.16) and satiety responsiveness (r = -0.11) were negatively correlated with BMI z-score at 3 years, while enjoyment of food (r = 0.12) was positively correlated, p < 0.05. In conclusion, we found a revised 7-factor structure of the CEBQ more appropriate for examining eating behavior in 3 year old children in the Singapore setting. Further replication studies in a separate cohort study are warranted before further use of these factor structures generated.

Background Malnutrition and anemia affect large numbers of young children living in poor areas of China. Multi-micronutrient deficiencies may be related to the prevalence of anemia in different populations, and identifying the risk factors that render children susceptible to anemia is the first step in combating anemia effectively. Methods In this cross-sectional study, a total of 1370 children under 3 years old were selected based on probability proportional to size sampling principles from poor counties of China. Basic characteristics data were collected by questionnaire; then anthropometrics and hemoglobin were measured in the field and anemia prevalence evaluated. Venous blood was drawn from children aged 12–35 months (N = 553) to evaluate micronutrient status. Logistic regression was used to identify the risk factors for children’s anemia. Results Among children aged 0–35 months, the prevalence of stunting, low body weight and wasting was 17.5%, 8.6% and 5.1%, respectively, and 25.6% of the children were affected by anemia, with more anemic infants and younger children than older children (P <0.01). There were 26.5%, 12.8%, 14.1% and 20.0% of the children aged 12–35 months affected by iron deficiency, vitamin D deficiency, folic acid deficiency and vitamin B12 deficiency, respectively. For children aged 0–11 months who were breastfed, the mothers’ anemic status was the only factor associated with the child’s anemia (OR = 2.6; 95% CI: 1.2–5.4, P < 0.05). For children aged 12–35 months, multivariate logistic regression indicated that anemia was significantly associated with iron and vitamin B12 deficiency (OR = 5.3; 95% CI: 1.9–14.5, P < 0.01) and monotonous diet (OR = 2.3; 95% CI: 1.1–4.7, P < 0.05) after adjusting for age and gender. Conclusion The prevalence of anemia was higher in children under 2 years old and requires urgent intervention. An effective intervention strategy should include iron and vitamin B12 supplements, improving
Using a sample of 156 Chinese children aged 2-3 years and their parents, this study examined the effects of socio-economic status, specifically family income and parental education, on the children's internalizing and externalizing psychopathology and whether these effects were mediated by mother-child and father-child conflict. Results indicated that family income, maternal education and paternal education all negatively predicted externalizing symptoms. Income also negatively predicted internalizing symptoms among boys but not girls. Maternal education negatively predicted internalizing symptoms among girls but not boys. The effects of income on psychopathology were fully mediated by mother-child and father-child conflict. In contrast, the effects of education were not mediated or only partially mediated by conflict. Findings are discussed in the framework of the family stress model.

Primary lymphangiomas or lymphangiomatous polyps of the palatine tonsil are rare benign lesions that are described infrequently in the literature. The majority of the published cases concern adults. We report a case of a lymphangiomatous lesion of the right palatine tonsil of a 9-year-old boy. Our clinical suspicion was confirmed by the histological examination after tonsillectomy and the diagnosis of primary lymphangioma of the tonsil was made. In this case we discuss the clinical and histopathological features of this lesion and present a short review of the current literature. PMID:27872780

Mediastinal teratomas are a rare, albeit an important differential diagnosis of anterior/middle mediastinal masses in young adults and various atypical presentations have been reported. The authors report a case of a 17-year-old boy who presented with a 2-month history of worsening shortness of breath and pleuritic chest pain. A massive left-sided pleural fluid collection was seen on a chest radiograph (CXR). The pleural fluid was drained and a CT Thorax confirmed the presence of a cystic mass. Following re-accumulation of the fluid, thoracotomy was performed and a benign mediastinal teratoma excised. The patient remained well with no evidence of recurrence on follow-up CXRs a year post operatively.

There are multiple cardiac etiologies for wheezing and respiratory distress which require a high degree of suspicion for the pediatrician to diagnose. We present a case of a patient with a history of long-standing mild persistent asthma with minimal improvement on controller and bronchodilator therapies who presented to the emergency room with acute respiratory distress. When he demonstrated a lack of improvement with traditional respiratory therapies, additional etiologies of respiratory distress were considered. Ultimately an echocardiogram was performed, which revealed the diagnosis of cor triatriatum. He underwent surgical resection of his accessory membrane and has had no additional symptoms of asthma since repair. PMID:28044119

Herein we describe the case of a 1-month-old boy with acute viral myocarditis, who presented with two kinds of paroxysmal supraventricular tachycardia, and who was cured after medical treatment. He was brought to the emergency room with poor feeding due to fever. On the third day of hospitalization, a narrow QRS tachycardia (180-200 beats/min) was detected. Echocardiography showed a high echoic area at the atrial septum around the atrioventricular node. The patient was clinically diagnosed with acute myocarditis. The narrow QRS tachycardia was diagnosed as incessant junctional ectopic tachycardia. The patient was treated with propranolol and landiolol. The frequency of the tachycardia decreased, but a different narrow QRS tachycardia was detected on the 15th day of hospitalization on electrocardiogram (220 beats/min), which was ascribed to atrioventricular nodal re-entrant tachycardia. Atenolol was effective for the tachycardia. At 2 years follow up, cardiac function was normal and tachycardia had not recurred.

Sucking habits and their connection with family background was investigated in 3-year-old Finnish children. The association between sucking habits and malocclusion was also studied. The study was based on a survey with stratified randomized cluster sampling, confidential questionnaires, and clinical dental examinations. Dummy (pacifier) use was often associated with a negligent attitude towards the child's toothbrushing. This may imply that these parents need more support, encouragement, and counseling from the well-baby clinic than others. Sucking habits were strongly associated with malocclusion.

A three-year-old girl presented with primary complaint of severe low back pain with radiation to both lower limbs below the knees since 2 months following history of fall and marked restriction of her daily routine activities. After clinicoradiological evaluation she was diagnosed of having dysplastic L5-S1 spondyloptosis. A staged procedure was planned after thorough discussion with her parents. During initial stage she underwent posterior decompression along L5-S1 segment including exposure of bilateral L5 and S1 nerve roots followed by instrumented reduction (L3-S2 5.5 mm pedicle screws) utilizing a rotational-translational technique. No interbody fusion was done at L5-S1 level and inner nuts of bilateral L3, L4, and S2 screws were intentionally kept loose. Subsequently after about symptom-free three-year follow up, she presented with recurrence of symptoms and underwent revision surgery as per initial plan discussed with her parents. Removals of posterior implants were done followed by stabilization with larger diameter pedicle screws (6.5 mm) at L5 and S1 level. During the same stage through anterior transperitoneal approach L5-S1 interbody fusion was done. At one-year follow-up after second-stage definitive surgery, patient remains symptom-free and fully active without any radiological evidence of reduction loss or implant failure. PMID:28357146

We report the occurrence of symptomatic methemoglobinemia in a previously healthy boy, who presented with severe acute hemolysis after fava bean ingestion. The methemoglobinemia revealed a previously unrecognized glucose-6-phosphate dehydrogenase (G6PD) deficiency. We discuss the pathophysiology of severe methemoglobinemia when associated with acute hemolysis, favism, and the common African G6PD A-variant [G6PD, VAL68MET, ASN126ASP]. In conclusion, screening for G6PD deficiency must be considered in symptomatic methemoglobinemia, especially in young boys, when associated with intravascular hemolysis.

Infants' sensitivity to social or behavioral contingency has been examined in the field of developmental psychology and behavioral sciences, mainly using a double video paradigm or a still face paradigm. These studies have shown that infants distinguish other individuals' contingent behaviors from non-contingent ones. The present experiment systematically examined if this ability extends to the detection of non-humanoids' contingent actions in a communicative context. We examined two- to three-year-olds' understanding of contingent actions produced by a non-humanoid robot. The robot either responded contingently to the actions of the participants (contingent condition) or programmatically reproduced the same sequence of actions to another participant (non-contingent condition). The results revealed that the participants exhibited different patterns of response depending on whether or not the robot responded contingently. It was also found that the participants did not respond positively to the contingent actions of the robot in the earlier periods of the experimental sessions. This might reflect the conflict between the non-humanlike appearance of the robot and its humanlike contingent actions, which presumably led the children to experience the uncanny valley effect.

Based on cortisol release, a variety of situations to which domestic horses are exposed have been classified as stressors but studies on the stress during equestrian training are limited. In the present study, Warmblood stallions (n=9) and mares (n=7) were followed through a 9 respective 12-week initial training program in order to determine potentially stressful training steps. Salivary cortisol concentrations, beat-to-beat (RR) interval and heart rate variability (HRV) were determined. The HRV variables standard deviation of the RR interval (SDRR), RMSSD (root mean square of successive RR differences) and the geometric means standard deviation 1 (SD1) and 2 (SD2) were calculated. Nearly each training unit was associated with an increase in salivary cortisol concentrations (p<0.01). Cortisol release varied between training units and occasionally was more pronounced in mares than in stallions (p<0.05). The RR interval decreased slightly in response to lunging before mounting of the rider. A pronounced decrease occurred when the rider was mounting, but before the horse showed physical activity (p<0.001). The HRV variables SDRR, RMSSD and SD1 decreased in response to training and lowest values were reached during mounting of a rider (p<0.001). Thereafter RR interval and HRV variables increased again. In contrast, SD2 increased with the beginning of lunging (p<0.05) and no changes in response to mounting were detectable. In conclusion, initial training is a stressor for horses. The most pronounced reaction occurred in response to mounting by a rider, a situation resembling a potentially lethal threat under natural conditions.

Birt-Hogg-Dubé syndrome is an uncommon genodermatosis characterized by hair follicle hamartomas and an increased risk of pneumothorax and renal cell carcinoma. Recognition of cutaneous manifestations is essential because it allows for early screening and management of systemic complications. We present the case of an 8-year-old boy with a recently described cystic and comedonal variant of the classic fibrofolliculoma, which had been present since birth.
Background We report on a 6-year-old Turkish boy with profound sensorineural deafness, balance disorder, severe disorder of oral motor function, and mild developmental delay. Further findings included scaphocephaly, plagiocephaly, long palpebral fissures, high narrow palate, low-set posteriorly rotated ears, torticollis, hypoplastic genitalia and faulty foot posture. Parents were consanguineous. Methods and results Computed tomography and magnetic resonance imaging showed bilateral single widened cochlear turn, narrowing of the internal auditory canal, and bilateral truncation of the vestibulo-cochlear nerve. Microarray analysis and next generation sequencing showed a homozygous deletion of chromosome 5q31.1 spanning 115.3 kb and including three genes: NEUROG1 (encoding neurogenin 1), DCNP1 (dendritic cell nuclear protein 1, C5ORF20) and TIFAB (TIFA-related protein). The inability to chew and swallow, deafness and balance disorder represented congenital palsies of cranial nerves V (trigeminal nerve) and VIII (vestibulo-cochlear nerve) and thus a congenital cranial dysinnervation disorder. Conclusions Based on reported phenotypes of neurog1 null mutant mice and other vertebrates, we strongly propose NEUROG1 as the causative gene in this boy. The human NEUROG1 resides within the DFNB60 locus for non-syndromic autosomal recessive deafness on chromosome 5q22-q31, but linkage data have excluded it from being causative in the DFNB60 patients. Given its large size (35 Mb, >100 genes), the 5q22-q31 area could harbor more than one deafness gene. We propose NEUROG1 as a new gene for syndromic autosomal recessive hearing loss and congenital cranial dysinnervation disorder including cranial nerves V and VIII. PMID:23419067

We report the case of a 13-year-old prepubertal boy who presented with a left-sided proptosis, bilateral papilloedema and hydrocephalus who was subsequently diagnosed with a giant prolactinoma invading the left orbit. He was commenced on dopamine receptor agonists in the form of quinagolide and cabergoline, and made an excellent response to medical therapy alone, with resolution of hydrocephalus, restoration of normal vision and a 98% reduction in serum prolactin. The rapid improvement achieved negated the requirement for surgery and this highlights the efficacy of the dopamine agonists in the management of giant prolactinomas, even in the presence of neurological symptoms.

Inflammatory myofibroblastic tumors (IMT) develop as a non-neoplastic proliferation of myofibroblasts in a myxoid to collagenous stroma admixed with inflammatory cells. The symptoms depend on the specific location of the tumor, which can be anywhere, but is particularly in the respiratory system. Thus, patients with IMT can present with a variety of findings. A pediatric patient with IMT who presented with cough, breathlessness, polyuria-polydipsia, and convulsions is described in this report. PMID:26777048

X-linked inhibitor of apoptosis (XIAP) deficiency, also known as X-linked lymphoproliferative syndrome type 2 (XLP2), is a rare inherited primary immunodeficiency resulting from the XIAP (also known as BIRC4) mutation. XIAP deficiency is mainly associated with familial hemophagocytic lymphohistiocytosis (HLH) phenotypes, and genetic testing is crucial in diagnosing this syndrome. Allogeneic hematopoietic stem cell transplantation (HSCT) is currently the only successful strategy for the treatment of this disease; however, a limited number of studies has been published concerning the outcomes of allogeneic HSCT in patients with XIAP deficiency. The present study reported a successful allogeneic HSCT performed to treat XIAP deficiency in a Chinese boy presenting with HLH. Polymerase chain reaction and DNA sequencing were performed to confirm the diagnosis of XIAP deficiency, and allogeneic HSCT was performed. Genetic tests revealed a two-nucleotide deletion (c.1021_1022delAA) in the patient, which was inherited from his mother, and resulted in frameshift mutation and premature stop codon (p.N341fsX348); this is considered to be a disease-causing mutation. The XIAP deficiency patient underwent allogeneic HSCT, receiving busulfan-containing reduced intensity myeloablative conditioning regimen, with a good intermediate follow-up result obtained. Therefore, genetic testing is essential to confirm the diagnosis of XIAP deficiency and detect the carrier of mutation. The present case study may promote the investigation of allogeneic HSCT in patients with XIAP deficiency. PMID:27602064

The mitochondrial pyruvate dehydrogenase enzyme complex (PDHC) plays an important role in aerobic energy metabolism and acid-base equilibrium. PDHC contains of 5 enzymes, 3 catalytic (E1, E2, E3) and 2 regulatory, as well as 3 cofactors and an additional protein (E3-binding protein) encoded by nuclear genes. The clinical presentation of PDHC deficiency ranges from fatal neonatal lactic acidosis to chronic neurologic dysfunction without lactic acidosis. Paroxysmal neurologic problems such as intermittent ataxia, episodic weakness, exercise-induced dystonia and recurrent demyelination may also be seen although they are rare. Here, we present an 8-year-old boy complaining of acute proximal muscle weakness of upper and lower extremities with normal mental status. He had a history of Guillain-Barré-like syndrome at the age of 2 years. Electrophysiologic studies showed sensorial polyneuropathy findings in the first attack and sensorimotor axonal polyneuropathy findings in the last attack. The genetic analysis revealed a previously reported hemizygote novel mutation of the PDHA1 gene (p.A353T/c.1057G > A), which encodes the E1α subunit of PDHC. Thiamine was ordered (15 mg/kg/day), dietary carbohydrates were restricted and clinical findings improved in a few weeks. This rare phenotype of PDHC deficiency is discussed.

The authors present a case of Chiari malformation manifesting as isolated trismus, describe the typical symptoms associated with Chiari malformation, and discuss the potential anatomical causes for this unique presentation. A 3-year-old boy presented with inability to open his jaw for 6 weeks with associated significant weight loss. The results of medical and radiological evaluation were negative except for Type I Chiari malformation with cerebellar tonsils 12 mm below the level of the foramen magnum. The patient underwent Chiari decompression surgery. Postoperatively, his ability to open his mouth was significantly improved, allowing resumption of a regular diet. Postoperative MRI revealed almost complete resolution of the syringobulbia. To the best of the authors' knowledge, this is the first reported case of isolated trismus from Chiari malformation with syringobulbia.

On most previous nuclear detonations, signatures and quantitative measurements of the electric-field signals associated with the detonations was obtained at distances such that normal radiation field characteristics apply. On Small Boy, measurements were made from stations located much closer in, such as to be inside, on the boundary of and just outside the limits of the ionized sphere created by the nuclear burst. The electric-field characteristics in these regions were unknown. In the hope of providing continuity from the region of the unknown into the reasonably well-understood region of the radiation field, this project was requested to make the typical radiation-field type of measurement that had been made on previous detonations. This report covers the signature characteristics and quantitative measurements of the electric-field signal from Small Boy as seen from outside the immediate region of theoretical generating mechanism.

Precocious puberty in boys is defined as the onset of puberty before the age of 9 years. It is divided into two categories: central precocious puberty, characterized by the premature activation of the hypothalamic-pituitary-gonadal axis, and peripheral precocious puberty presents when premature sexual development is dependent on steroid production regardless of gonadotropin secretion. Although precocious puberty occurs more frequently in girls, in the case of boys it is more often associated with identifiable organic disorders of the central nervous system, adrenal glands or testes. The diagnosis should include detailed anamnesis and clinical examination, measurement of pituitary and sex hormones, assessment of bone age, and imaging of the hypothalamus, pituitary gland, adrenal glands and testes. Indications for treatment are based on the type of precocious puberty and its progression rate, advancement of bone age, predicted adult height and psychological evaluation. The purpose of this article was to discuss the etiopathogenesis of precocious puberty in boys and to provide the approach to its diagnosis, differentiation and treatment.

We present a 3-yr-old girl with a virilizing adrenocortical carcinoma invading into the right atrium with histological high-grade malignancy and p53 mutation. Development of facial acne and pubic hair were noted at 3 yr and 2 mo. The levels of androgens were high. Diurnal variation in ACTH and cortisol were absent. Abdominal computed tomography revealed a large right suprarenal mass, with extension into the inferior vena cava and right atrium. Based on the diagnosis of a right virilizing adrenocortical tumor with Cushing syndrome, surgery was performed by a combined thoracoabdominal approach with the patient on cardiopulmonary bypass. The tumor was 7 × 5.5 × 3.5 cm in size, and weighed 95 g. The histological diagnosis was adrenocartical carcinoma with high-grade malignancy according to the category of Weiss. A heterozygous mutation of the p53 tumor-suppressor gene (codon 248 CGC→TGG) was found. We did not perform adjuvant chemotherapy because of radical resection on macroscopic observation and no metastasis in radiological findings. Five months after the surgery, her chest X ray and computed tomography revealed multiple lung metastases and a single liver metastasis. In this type of patient with histological high-grade malignancy and p53 mutations, postoperative adjuvant chemotherapy is indicated even if macroscopic total surgical removal had been performed.

Accurate and easy-to-use methods to assess free-living energy expenditure in response to physical activity in young children are scarce. In the present study, we evaluated the capacity of (1) 4 d recordings obtained using the Actiheart (mean heart rate (mHR) and mean activity counts (mAC)) to provide assessments of total energy expenditure (TEE) and activity energy expenditure (AEE) and (2) a 7 d activity diary to provide assessments of physical activity levels (PAL) using three sets of metabolic equivalent (MET) values (PALTorun, PALAdolph and PALAinsworth) in forty-four and thirty-one healthy Swedish children aged 1·5 and 3 years, respectively. Reference TEE, PALref and AEE were measured using criterion methods, i.e. the doubly labelled water method and indirect calorimetry. At 1·5 years of age, mHR explained 8 % (P= 0·006) of the variation in TEE above that explained by fat mass and fat-free mass. At 3 years of age, mHR and mAC explained 8 (P= 0·004) and 6 (P= 0·03) % of the variation in TEE and AEE, respectively, above that explained by fat mass and fat-free mass. At 1·5 and 3 years of age, average PALAinsworth values were 1·44 and 1·59, respectively, and not significantly different from PALref values (1·39 and 1·61, respectively). By contrast, average PALTorun (1·5 and 3 years) and PALAdolph (3 years) values were lower (P< 0·05) than the corresponding PALref values. In conclusion, at both ages, Actiheart recordings explained a small but significant fraction of free-living energy expenditure above that explained by body composition variables, and our activity diary produced mean PAL values in agreement with reference values when using MET values published by Ainsworth.

Acute motor and sensory axonal neuropathy (AMSAN) is a recently described subtype of Guillain-Barré syndrome characterized by acute onset of distal weakness, loss of deep tendon reflexes and sensory symptoms. Electrophysiological studies show mildly reduced nerve conduction velocities combined with a marked reduction of muscle action and sensory nerve action potentials. Here, we report a 15-year-old boy who suffered from severe burning and knife-like pain that increased over a period of three months and resulted in a disrupted sleep pattern and suicidal intentions as well as marked loss of weight. In addition, he developed muscle weakness in his hands and feet. Neurophysiological and histopathological studies revealed AMSAN. Marked improvement of his condition was achieved by treatment with intravenous immunoglobulins, high-dose methylprednisolone, and a combination of gabapentin, antidepressants, and an oral morphine.

A 3-year-old boy was referred to the dermatology department with a 12-month history of facial erythema associated with a papular-pustular facial eruption consistent with childhood acne. He had been diagnosed with XYY syndrome identified during genetic analysis for cardiac anomalies at birth. XYY syndrome is an aneuploidy of the sex chromosomes which affects 1 in 1000 male births. It is often asymptomatic and identified incidentally following genetic analysis for other conditions. The syndrome can be associated with an increased risk of learning difficulties and delayed language skills. Early diagnosis could alert physicians to the possibility of subtle developmental and learning abnormalities and result in prompt management. Our case highlights the fact that the presence of childhood acne could aid in the early detection of XYY syndrome.

Chronic granulomatous disease (CGD) is a rare inherited disorder of neutrophil oxidative burst. In patients with CGD, phagocyte destruction of catalase-producing organisms is impaired, resulting in recurrent and potentially fatal infections. Burkholderia cepacia, a catalase-producing organism, is known to infect patients with dysfunctional immune systems. We report a case of a 3-year-old boy with this rare infection that unravelled the diagnosis of CGD.

When enumerating small sets of elements nonverbally, human infants often show a set-size limitation whereby they are unable to represent sets larger than three elements. This finding has been interpreted as evidence that infants spontaneously represent small numbers with an object-file system instead of an analog magnitude system (Feigenson, Dehaene & Spelke, 2004). In contrast, non-human animals and adult humans have been shown to rely on analog magnitudes for representing both small and large numbers (Brannon & Terrace, 1998; Cantlon & Brannon, 2007; Cordes, Gelman, Gallistel & Whalen, 2001). Here we demonstrate that, like adults and non-human animals, children as young as 3 years of age spontaneously employ analog magnitude representations to enumerate both small and large sets. Moreover, we show that children spontaneously attend to numerical value in lieu of cumulative surface area. These findings provide evidence of young children's greater sensitivity to number relative to other quantities and demonstrate continuity in the process they spontaneously recruit to judge small and large values.

An 8.25-year-old boy was incidentally found to have systemic hypertension of the upper extremities. Blood pressures of the upper extremities were 142-150/86-98 mmHg, and those of the lower extremities 110-116/60-66 mmHg. Doppler echocardiography showed in-stent restenosis of the aortic coarctation. Traditional high-pressure balloon angioplasty failed to dilate this inveterate in-stent restenosis. Instead, a cutting balloon angioplasty was performed. The lumen was dilated from 4.80 mm to 7.89 mm. The pressure gradient dropped from 32 mmHg to 9 mmHg. Blood pressures of the upper extremities were 112-116/76-78 mmHg, and those of the lower extremities 100-104/70-72 mmHg. This paper highlights that a cutting balloon angioplasty can serve as a juste milieu to relieve in-stent restenosis of the aortic coarctation when traditional high-pressure balloon angioplasty is debatable.

An adolescent boy presented with episodic wolf-like aggressive behaviors, for which his rural community planned an exorcism. Admission to a tertiary care hospital revealed an adolescent suffering an array of severe psychiatric symptoms, which best fit the diagnosis of reactive attachment disorder (RAD). The differential diagnosis included delusional disorder, mood problems, anxiety, schizophrenia, and “feral child” syndrome. Nosology and pathophysiology as well as pharmacological and psychosocial treatments are discussed. We highlight the importance of early life events in determining mental health risk and resiliency.

Boy culture is out of sync with school culture. There are several reasons for this, including zero tolerance policies that are too often taken to extremes, the lack of male teachers, and the compression of the curriculum. What's more, boy culture is not socially accepted, and boys quickly come to feel that they are not good at school. For many…

A 3-year-old boy had abnormal liver function, which was found in physical examination, for 5 months before admission. He had no symptoms such as anorexia, poor appetite, and jaundice, had normal growth and development, and showed no hepatosplenomegaly. Laboratory examination revealed significantly reduced ceruloplasmin (35 mg/L), as well as negative hepatotropic virus, cytomegalovirus, and Epstein-Barr virus. There were normal muscle enzymes, blood glucose, and blood ammonia and negative liver-specific autoantibodies. The boy had negative K-F ring and normal 24-hour urine copper (0.56 μmol/L). The ATP7B gene testing for the boy, his sister, and their parents detected two novel missense mutations in the boy and his sister, i.e., compound heterozygous mutations in exon 7 (c.2075T>C, p.L692P) and exon 13 (c.3044T>C, p.L1015P), which were inherited from their father and mother, respectively. Wilson's disease was confirmed by genetic diagnosis in the boy and his sister. The boy and his sister were given a low-copper diet. The boy was administered with penicillamine for decoppering and zinc supplement against copper uptake. His sister received zinc supplement alone because no clinical symptoms were observed. The boy showed normal liver function in the reexamination after 3 months of treatment.

Girls outscore boys in reading proficiency levels; the gender gap is startling and concerning. The myth that boys won't read or that it's not "cool" for boys to love reading plays a big part in how these low levels come to be. Low expectations from teachers, and an assumption that boys prefer physical activity, mean that boys often don't find…

A reconstruction of the Little Boy weapon allowed experiments to evaluate yield, leakage measurements for comparison with calculations, and phenomenological measurements to evaluate various in-situ dosimeters. The reconstructed weapon was operated at sustained delayed critical at the Los Alamos Critical Assembly Facility. The present experiments provide a wealth of information to benchmark calculations and demonstrate that the 1965 measurements on the Ichiban assembly (a spherical mockup of Little Boy) were in error.

As adolescence is a critical period of development, and as boys are less inclined than girls to approach the school facility for adolescent counselling, segregated consulting hours were introduced for boys to attract those with problems. The frequency of consultations by boys increased by 25 per cent, and 70 per cent of the boys reported a preference for the segregated consulting hours; 75 per cent appreciated the absence of girls from the waiting room; and of the 42 per cent with special preferences regarding the gender of the staff encountered, half reported preferring a man. Most of the boys presented with defined problems, though many revealed other problems, often relating to sexuality, in the course of consultation. The availability of segregated consulting hours for boys with adolescent problems is important, and often the only way to reach young boys who need help.

"Can we do anything for you?" The question was embarrassing. Henry had been poked and prodded and preserved far beyond his wishes. In a medical system that scorns comfort care, a resident physician is troubled by the case of an elderly man with poor quality of life. An awkward attempt at a Boy Scout service project emphasizes how poorly we comfort the terminally ill despite modern technology and interventionalism.

Extra-hepatic manifestations have seldom been described with hepatitis A, which usually manifests as mild hepatic dysfunction. We report a 3-year-old boy presenting with 3 days of fever, vomiting, abdominal distention and scleral icterus. On examination, he had tachypnea, hepatosplenomegaly, ascites and right-sided pleural effusion. A diagnostic pleural tap yielded a milky, lymphocyte-predominant exudative aspirate, with pleural fluid triglycerides of 175 mg/dl, suggestive of chylothorax. Serology for anti-HAV IgM was positive in both blood and pleural fluid. The massive effusion causing collapse of the underlying lung was drained by tube thoracostomy, which was followed by complete resolution within 2 weeks. This is the first reported case of chylothorax associated with hepatitis A infection. This report highlights that pleural effusion associated with hepatitis A infection is usually a benign, self-limiting condition which should be considered in the differential diagnosis of pleural effusion or chylothorax in a patient with acute viral hepatitis.

This study was designed to examine the contribution of multiple risk factors to early internalizing problems and to investigate whether family and ecological context moderated the association between child temperament and internalizing outcomes. A sample of 1,202 mothers of 2- and 3-year-old children completed a survey of child social-emotional functioning, family environment, and violence exposure. Child temperament, maternal affective symptoms, and family expressiveness were associated with child anxiety and depression problems. Violence exposure was related only to child anxiety. When maternal affective symptoms were elevated, inhibited girls but not boys were rated as more anxious and youngsters with heightened negative emotionality were rated as more depressed. Family expressiveness moderated the association between inhibited temperament and anxiety symptoms.

Torsion of a communicating hydrocele is extremely rare, and the cause is unclear. We report the case of a 3-year-old boy referred to us with acute scrotum. Operative findings revealed torsion of a communicating hydrocele with a 360-degree rotation of the distal end. We performed surgical excision of the necrotic cystic mass and high ligation of the peritoneal communication. A high index of suspicion is required for the correct diagnosis and treatment of this condition, which should be included among the causes of acute scrotum in childhood. PMID:28003926

In the UK, the media are reporting increasing rates of childhood suicide, while highlighting that increasing numbers of pre-adolescent boys (in relation to girls) are diagnosed as mentally ill. In response, academic, professional and political commentators are explaining this as a consequence of gender. One way of doing this has been to apply adult defined understandings of men and masculinities to the attitudes and behaviours of pre-adolescent boys. As a consequence, explanations of these trends point to either 'too much' masculinity, such as an inability to express feelings and seek help, or 'not enough' masculinity that results in isolation and rejection from significant others, such as peer groups. Using a discourse analysis of semi-structured interviews with 28 children aged 9-13 (12 male, 16 females) and 12 school staff at a school in North East England, this article questions the viability of using normative models of masculinity as an explanatory tool for explaining boys' behaviours and suggests that researchers in the field of gender and suicide consider how boys' genders may be constituted differently. We develop this argument in three ways. First, it is argued that studies that use masculinity tend to reduce the formation of gender to the articulation of power across and between men and other men and women. Second, we argue that approaches to understanding boys' behaviours are simplistically grafting masculinity as a conceptual frame onto boy's attitudes and behaviours. In response, we suggest that it is important to re-think how we gender younger boys. The final section focuses specifically on the ways that boys engage in friendships. The significance of this section is that we need to question how notions of communication, integration and isolation, key features of suicide behaviours, are framed through the local production of friendships.

Neutron dose rates at several angular locations and at distances out to 0.5 mile have been measured during critical operation of the Little Boy replica. We used modified remmetes and thermoluminescent dosimetry techniques for the measurements. The present status of our analysis is presented including estimates of the neutron-dose-relaxation length in air and the variation of the neutron-to-gamma-ray dose ratio with distance from the replica. These results are preliminary and are subject to detector calibration measurements.

The late Bronze Age wall painting the Boxing Boys (c. 17th-16th century BCE) was excavated in the ancient town of Akrotiri on the Greek island of Thera. This article considers a medical interpretation for the spinal-pelvic anomaly in the anatomy of one of the boys. The artist has depicted a combination of structural anatomical adjustments diagnostic of spondylolisthesis, a forward slippage of one of the lumbar vertebrae. The accurate portrayal of the surface appearance of this condition suggests that the artist painted directly from a live subject. Thus, the Boxing Boys mural may be the earliest visual record of a sports-induced injury. Although the meaning of the wall paintings is unclear, the wild goats (agrimia) on the adjoining walls simulate swayback as a reflection of the boy's torso deformity and share other features with the boxers, adding to the unifying characteristics of the room. The abnormal morphology appears to be the earliest achievement of transforming disease into aesthetic charm on a monumental scale.
The "problem" of boys' achievement in the United Kingdom has emerged as part of a policy response to a crisis in the post-war social settlement.

This study used hegemonic masculinity theory to examine the intersection of masculinities and school physical education from the perspectives of boys who embodied masculinities that were marginalized. Over a 13-week period using present-focused, student-centered, qualitative methodological approaches, we observed, interviewed, and worked in small groups with 5 middle school boys from two schools. We identified three significant themes that merge the stories and experiences of masculinity hierarchies in sport-based physical education. First, we found that four social practices (content, pedagogies, teacher-student relationships, and peer cultures) in these physical education settings privileged some masculinities over others. Second, we examined the role that embodiment played, both in how the boys wore their oppression and in how their bodies resisted marginalizing situations. Third, we describe the contrasts these boys drew between physical activities experienced in sport-based physical education and physical activity experiences in other areas of their lives. We used Connell and Messerschmidt's (2005) reconceptualization of the theory of hegemonic masculinity for understanding how competitive sport-based physical education functioned to oppress boys with masculinities that were deemed abnormal. Additionally, we introduce feminist poststructuralism as a possible theoretical lens for interpreting boys' bodies as also being active agents in social practices rather than being only passive objects who are oppressed and dominated.

Urinary 1-hydroxypyrene (1-OHP) is a biomarker of polycyclic aromatic hydrocarbon (PAH) exposure. We measured urinary 1-OHP in 48 children 3 years of age in Mariupol, Ukraine, who lived near a steel mill and coking facility and compared these with 1-OHP concentrations measured in 42 children of the same age living in the capital city of Kiev, Ukraine. Children living in Mariupol had significantly higher urinary 1-OHP and creatinine-adjusted urinary 1-OHP than did children living in Kiev (adjusted: 0.69 vs. 0.34 μmol/mol creatinine, p < 0.001; unadjusted: 0.42 vs. 0.30 ng/mL, p = 0.002). Combined, children in both cities exposed to environmental tobacco smoke in their homes had higher 1-OHP than did children not exposed (0.61 vs. 0.42 μmol/mol creatinine; p = 0.04; p = 0.07 after adjusting for city). In addition, no significant differences were seen with sex of the children. Our sample of children in Mariupol has the highest reported mean urinary 1-OHP concentrations in children studied to date, most likely due to their proximity to a large industrial point source of PAHs.

Recent research has found that linguistic cues may affect children's number word acquisition. Two studies were undertaken to evaluate the use of singular/plural markings and small number words in Chinese and English and its effect on children's number concepts. The first study utilized the CHILDES data and investigated how singular/plural markings…

Currently, there is no research in Australia that systematically investigates the underlying beliefs for mothers' decisions regarding their young child's nutritional needs based on current guidelines. We aimed to determine, using a Theory of Planned Behaviour (TPB) belief-based approach, key beliefs that guide mothers' decisions with regards to: (a) providing their child with a wide range of foods from the five food groups ('healthy eating'); and (b) limiting their child's intake of 'discretionary choices' (e.g. lollies). Mothers (N = 197, M age = 34.39, SD = 5.65) completed a main questionnaire either online or on hard copy (paper-based), with a 1-week phone follow-up of the target behaviours (N = 161). Correlations and multiple regression analyses were conducted, and a number of key behavioural, normative, and control beliefs emerged for both healthy eating and discretionary choice behaviours. For healthy eating, mothers identified behavioural beliefs 'improving my child's health' and 'resistance from my child'; normative beliefs 'other family members' and 'spouse/partner'; and control beliefs 'child's food preferences'. For discretionary choices, behavioural beliefs 'maintain consistent energy levels in my child' for intentions, and 'give my child their required nutritional intake'; normative beliefs 'spouse/partner', 'healthcare professionals' and 'friends'; and control beliefs 'child's food preferences' were identified. These findings can inform the development of future intervention programmes aimed at modifying mothers' child feeding practices to encourage healthy eating and limit discretionary choice intake and, ultimately, increase the life expectancy of the current generation of children.

Mycotic encephalitis caused severe ataxia and other neurologic deficits in a horse. The finding of a single, large focus of cerebral malacia, with histopathologic evidence of fungal elements, suggested infection was a result of direct transfer from the frontal sinuses, rather than hematogenous spread from the guttural pouch.

Before children learn the specific meanings of numerals like six, do they know that they represent precise quantities? Previous studies have reported conflicting evidence and have found that children expect numerals to label precise quantities in some tasks but not in others (Condry & Spelke, 2008; Sarnecka & Gelman, 2004). In this…

Repeatabilities (t) and heritabilities (h2) of racing time were estimated from data on 7,206 2- and 3-yr-old Standardbred pacers and trotters competing in 1-mile (1.6 km) charted races at six tracks between 1975 and 1978. A total of 38,487 records representing 2,387 sire progeny groups were divided into subsets by gait, age and track. Initially, the designation "class of race" was recognized as a subjective categorization that reflected nonrandom assignments of horses to races. After extensive investigation, we concluded that racing times should be adjusted by linear regression for the time of the winning horse (defined at the "pace" of the race). Residual regression coefficients of time on pace ranged from .61 +/- .08 to .79 +/- .05 s/s and appeared to adequately account for the environmental effects of class. Repeatabilities of adjusted times ranged from .32 +/- .08 to .55 +/- .04 and heritabilities ranged from -.25 +/- .22 to .66 +/- .16. Overall estimates of t and h2 (pooled over gaits, ages and tracks) were .44 +/- .01 and .29 +/- .03, respectively. When data were not adjusted for pace, the sire, horse and error variance component estimates were inflated by environmental effects (pooled t = .62; pooled h2 = .36). Racing time adjusted for pace is recommended for use as a selection criterion in Standardbred horses.

Three-year-old children were tested on three categorization tasks of increasing levels of abstraction (used with adult baboons in an earlier study): the first was a conceptual categorization task (food vs toys), the second a perceptual matching task (same vs different objects), and the third a relational matching task in which the children had to sort pairs according to whether or not the two items belonged to the same or different categories. The children were tested using two different procedures, the first a replication of the procedure used with the baboons (pulling one rope for a category or a relationship between two objects, and another rope for the other category or relationship), the second a task based upon children's prior experiences with sorting objects (putting in the same box objects belonging to the same category or a pair of objects exemplifying the same relation). The children were able to solve the first task (conceptual categorization) when tested with the sorting into boxes procedure, and the second task (perceptual matching) when tested with both procedures. The children were able to master the third task (relational matching) only when the rules were clearly explained to them, but not when they could only watch sorting examples. In fact, the relational matching task without explanation requires analogy abilities that do not seem to be fully developed at 3 years of age. The discrepancies in performances between children tested with the two procedures, with the task explained or not, and the discrepancies observed between children and baboons are discussed in relation to differences between species and/or problem-solving strategies.

There is a pantheon of literature and popular panic pointing toward the academic ascent of girls and the decline of boys. On the contrary, the reality is different: Boys are learning and succeeding in many places. Two studies find that the places where boys excel have several common characteristics, including teachers who relate to the boys…

CHILD syndrome (congential hemidysplasia with ichthyosiform nevus and limb defects) occurs, as a rule, exclusively in girls because of the underlying X-linked gene exerts a lethal effect on male embryos. In this report the characteristic manifestations of CHILD syndrome are described in a 2-year-old boy with a normal chromosome constitution 46,XY. This exceptional case is best explained by the assumption of an early somatic mutation and thus compatible with the concept of X-linked dominant male-lethal inheritance of this trait. 18 refs., 6 figs.

The present study examines the differences between levels of selected structural and functional features of boys 11-13 years in age from regions with varying levels of air pollution, including an industrial and rural region. The sample consisted of 213 boys from the industrial region and 98 from the rural region. Somatic, respiratory parameters and motor abilities were evaluated in both groups. The analysis of respiratory parameters revealed significantly better development of respiratory systems in boys from the rural region. Additionally, motor abilities were also better developed in boys from the rural region.

Acute lymphoblastic leukemia (ALL) is the most common cancer in children and adolescents. Clinical presentation often reflects bone marrow (BM) involvement and consequences of BM failure. Microscopic involvement of the testis is rare, occurring in about 2% of cases. We present a case of a 3-year-old child who displayed unilateral macroorchidism as the only clinical symptom of ALL. Although the patient presented with localized disease, he was treated with systemic chemotherapy without recurrence. In this report, we review the current literature on ALL testicular involvement, diagnosis and treatment. PMID:23042023

Recurrent abdominal pain remains one of the most common symptoms in pediatrics. We present the case of a 3-year-old girl who had recurrent episodes of abdominal pain requiring more than 13 visits to the emergency department. A diagnosis of ornithine transcarbamylase deficiency was eventually made. Urea cycle disorders often present beyond the neonatal period with frequent vomiting episodes; however, recurrent abdominal pain as a presenting symptom is unusual. Unnecessary invasive investigations of recurrent abdominal pain in childhood can be avoided by considering inborn errors of metabolism earlier in the differential diagnosis.

Boys appear to engage in eating disorder behavior, particularly nonpurging compensatory behaviors such as driven exercise and fasting, at higher rates than previously thought. Little is known about the development of these behaviors in adolescent boys. In a sample of 631 non-binge eating and non-purging boys studied once in 5th grade and 6 times over the 3 years of middle school (grades 6 through 8), we found that (a) for some youth, driven exercise and fasting were present from grade 6; (b) different boys progressed along different trajectories of engagement in driven exercise and fasting, with some boys engaging in no driven exercise or fasting (65.8 % and 83.5 %, respectively), some boys engaging in driven exercise and fasting throughout middle school (25.2 % and 16.5 %, respectively), and other boys discontinuing engagement in driven exercise (9 %); (c) 5th grade depression, eating expectancies, and thinness expectancies predicted subsequent trajectory group membership; and (d) boys engaging in driven exercise and fasting in 8th grade remained distressed. Boys' engagement in driven exercise and fasting behavior merits the attention of researchers and clinicians.

The transition to middle school often presents behavioral and academic challenges to youths. Boys of color (i.e., African American and Hispanic in this study) may be especially vulnerable. In this study, peer nominations of aggressive and academic behaviors as well as youths' perceptions of how these behaviors were related to popularity in peer networks were obtained from the spring semester of fifth grade through the spring semester of seventh grade, with the transition occurring as the students entered the sixth grade. The sample included 188 boys (71 Caucasian, 90 African American, and 27 Hispanic) from an urban school district in the northeastern United States. Trajectory analyses showed that African American boys scored lower in studentship and higher in rule-breaking and aggressive (both physical and social) behaviors prior to the transition, and such differences among ethnic groups were largely maintained during the transition. Hispanic boys displayed decreases in their studentship during the transition. African American boys' perception of how studentship affects popularity was more positive than other boys prior to the transition, but it decreased during the transition. African American boys also endorsed rule breaking and physical and social aggression more positively for popularity prior to the transition, whereas Caucasian and Hispanic boys' endorsement increased during the transition and eventually caught up with those of African American boys in seventh grade. A positive within-individual association was found between youths' popularity perception and their behavior for studentship, rule breaking, and physical aggression, which did not differ by ethnicity.

The discourse on Black boys tends to suggest that Black boys are in complete peril. We begin with evidence that Black boys are excelling in certain contexts (i.e., in certain states, in certain schools, and in certain courses). We then discuss the ways in which the narratives used by parents, teachers, and Black boys themselves may serve to further reinforce views that Black boys are beyond hope. Research on Black parents suggests that they tend to view their sons as vulnerable and have lower expectations for sons than for daughters. Studies of teachers show that they tend to view Black boys as unteachable, as social problems, and as scary. Research on Black boys shows that they are sometimes complicit in supporting these narratives by engaging in negative or ste reotypical behavior. We also include recent research that includes counter-narratives of Black boys. We end with suggestions for future research.

Objective: To compare sexual and behavioral puberty problems between intellectually disabled (ID) and normal boys in Yazd, Iran. Methods: In the present study, 65 intellectually disabled and 65 normal boys were included. The Child Behavior Check List (CBCL) was used to investigate behavioral problems. In order to study sexual problems, a questionnaire that was designed by the researchers was applie. Results: Anxiety, depression, social problems, attention problems, aggressiveness, and sexual problems were more frequent in intellectually disabled boys than in normal boys. On the other hand, regarding somatic complaints, withdrawal, thought problems, internalizing, delinquent behavior, and externalizing there was no difference between the two groups. Conclusion: Behavioral and sexual problems are more common in adolescent boys with intellectual disability (ID) than in normal boys during the puberty period. Therefore, puberty is an important period for intellectually disabled boys and their families; this should be taken into consideration by psychologists and clinicians. PMID:25053959
Research shows that boys have a tougher time that girls learning to read, and they score lower in reading achievement tests.

The purpose of our study was to examine whether girls and boys show patterns of problem-solving ability similar to those attributed by Kimura in 1992 to women and men, respectively. Subjects were 28 girls and 24 boys, aged 5-11 years, who were tested individually on matching ability, spatial memory, and ideational fluency, tasks on which women reportedly outperform men. No significant gender differences in these problem-solving abilities were found. On ideational fluency, the youngest girls were seven times more likely than young boys to give whimsical responses, but older girls were then times less likely than older boys to give whimsical responses. These results suggest that the patterns of visuospatial problem-solving abilities that Kimura ascribed to women and men are not present in preadolescent girls and boys.

A challenge design was used in two separate studies to investigate the effects of sucrose ingestion on the behavior and learning of hyperactive boys. In both studies, 16 boys were admitted to a clinical research center for 3 successive days, on each of which they were given a sucrose-free diet. On day 1, baseline levels on the learning tasks were established; on days 2 and 3 a challenge drink of either sucrose 1.75 gm/kg or a placebo (aspartame in equivalent sweetness) was presented, in a counterbalanced order. In the first study the challenge drink was administered 1 hour after lunch; in the second study it was given in the morning after an overnight fast. On days 2 and 3 of both studies, 37 behavioral (playroom observation and examiner ratings) and cognitive (learning and memory tasks) measures were collected, starting 1/2 hour after ingestion of the drink. The results of both studies revealed no differences between the boys' performance on the two challenge days. These findings undermine the hypothesis that sucrose plays a major role in accounting for the inappropriate behavior of hyperactive boys.

Aims To investigate risk factors for metabolic syndrome in prepubertal boys with Klinefelter syndrome. Methods Eighty-nine boys with Klinefelter syndrome, ages 4–12.9 years, and 34 age-matched control boys had height, weight, waist circumference and blood pressure measured and their parents completed a questionnaire about physical activity. The boys with Klinefelter syndrome also had measurement of lipids, fasting glucose and insulin. Insulin-glucose homeostasis model assessment was calculated, and the boys were evaluated for childhood metabolic syndrome. Results The Klinefelter syndrome and control groups were similar ages (7.5 ± 2.4 vs. 8.1 ± 2.3 years). Body mass index measurements were similar, but waist circumference was >90‰ in 30% of boys with Klinefelter syndrome versus 21% of controls. The mean daily time spent running was 42 min less in the Klinefelter syndrome versus control groups (p < 0.01). About 37% of the boys with Klinefelter syndrome had elevated LDL cholesterol, 24% had insulin resistance, and 7% met the three criteria for diagnosis of metabolic syndrome. Conclusions Truncal obesity, insulin resistance and metabolic syndrome are present in boys as young as 4–12 years with Klinefelter syndrome, and these occur in association with reduced running-type activity.

Caloric intake and expenditure of children in four families were assessed by nonparticipant observations of family dinners and school lunches. In each family there were one obese boy and one nonobese brother whose ages were within two years of each other. For family dinners the nonobese brother served as a control; for school lunches, a nonobese peer served as a control. The obese boys consumed more calories (766 +/- 290) than did their nonobese brothers at dinner (504 +/- 183) and far more (907 +/- 217) than their nonobese peers at lunch (500 +/- 386). The obese boys also ate faster (65.7 +/- 37.0 kcal/minute) than their brothers at dinner (31.7 +/- 13.8 kcal/minute) and far faster (103.5 +/- 40.9 kcal/minute) than their nonobese peers at lunch (46.2 +/- 22.5 kcal/minute). Time-sampled activity assessments showed the obese boys far less active than their controls inside the home, slightly less active outside the home, and equally active at school. When these activity values were converted into energy expenditure by measurement of oxygen consumption, obese boys expended more calories in moving than did their controls; as a result, there was no difference in energy expenditure between obese and nonobese boys at home and greater energy expenditure outside the home and at school. Increased intake, thus, and not decreased caloric output maintained the obesity of these four boys. In this respect, obesity in childhood may differ from obesity in adult life.

The purpose of the study was (1) to investigate gender role behaviors of boys with hypospadias compared with groups of unaffected boys and girls using parental reports and direct observations; and (2) to directly observe effects of socialization (mothers' presence) on children's gender role behaviors. Ages of 19 children with hypospadias ranged from 3 to 7 years, and each of them were matched to controls of unaffected boys and girls by age. All the children participated with their mothers. Children's gender role behaviors and their mothers' behaviors were evaluated using an observation coding system. Mothers also completed questionnaires regarding their children's gender role behaviors. Results indicated no atypical gender role behavior for the boys with hypospadias and no direct effects of socialization on their gender role behaviors. However, differences were found in negative communicative behaviors between boys with hypospadias and unaffected boys, suggesting a possible role of socialization.

Burkitt's lymphoma is not an uncommon malignancy in the paediatric population. It is a high-grade non-Hodgkin B-cell lymphoma which may present as endemic, sporadic and human immunodeficiency-associated subtypes. The African, or endemic, variant usually involves the maxilla and other facial bones while head and neck manifestations in sporadic Burkitt's lymphoma are rare. We described a case of oral Burkitt's lymphoma involving the right jaw in a 4-year-old boy. The patient presented with a rapidly-enlarging swelling of one month duration, toothache-like pain and radiographical appearance of 'floating teeth' in the right mandible. Incisional biopsy revealed small round tumour cells with scarce cytoplasm and multiple small nuclei interspersed by phagocytic macrophages. The tumour cells were immunopositivity for CD20 and CD10, expressed weak positivity for CD3, negative for CD5 and showed > 90% positivity for Ki-67. Tumour remission was achieved with six cycles of chemotherapy with the CHOP regime.

Some boys thrive in school; many do not. There is a growing consensus that many boys' scholastic performance is failing to keep up with the new knowledge economy. As troubling as this trend in boys' scholastic performance may be generally, school troubles are neither universal nor normative. The intriguing fact is that some boys in most schools…

More boys than girls are diagnosed with autism spectrum disorder; however, there are conflicting findings about whether they differ in their presentation. This study involved a survey of parents of school-aged children on the autism spectrum (171 parents of girls and 163 parents of boys) that was distributed via social media. The surveys provided insights regarding the characteristics of boys and girls (as perceived by parents) as well as some demographic information. There were very few differences reported regarding communication and social strengths and difficulties of boys and girls with autism. No differences were reported in the number of boys and girls on the autism spectrum with special interests or repetitive behaviours; however, significant differences were found in the types of special interests with boys and girls showing generally interests along traditional gender lines. Qualitative analysis of open comments indicated that some parents of girls on the autism spectrum described their daughter as trying to hide or mask her difficulties more but no parents of boys on the spectrum described this phenomenon.

The objective of this study was to test the effect of individual differences on appeal and use of video games. Participants were 299 adolescent boys from lower and higher secondary schools in the Netherlands and Belgium. In general, boys were most attracted to violent video games. Boys that scored higher in trait aggressiveness and lower in empathy were especially attracted to violent games and spent more time playing video games than did boys lower in trait aggressiveness. Lower educated boys showed more appreciation for both violent and nonviolent games and spent more time playing them than did higher educated boys. The present study showed that aggressive and less empathic boys were most attracted to violent games. The fact that heavy users of violent games show less empathy and higher aggressiveness suggests the possibility of desensitization. Other studies have shown that playing violent games increases aggressiveness and decreases empathy. These results combined suggest the possibility of a violence cycle. Aggressive individuals are attracted to violent games. Playing violent games increases aggressiveness and decreases empathy, which in turn leads to increased appreciation and use of violent games.

Self-report measures of physical activity (PA) are easy to use and popular but their reliability is often questioned. Therefore, the general aim of the present study was to investigate the association of PA questionnaires with accelerometer derived PA, in a sample of adolescent boys. In total, 191 pubertal boys (mean age 14.0 years) completed three self-report questionnaires and wore an accelerometer (ActiGraph GT1M) for 7 consecutive days. The PA questionnaires were: International Physical Activity Questionnaire-Short Form (IPAQ-SF), Tartu Physical Activity Questionnaire (TPAQ), and the Inactivity subscale from Domain-Specific Impulsivity (DSI) scale. All three questionnaires were significantly correlated with accelerometer derived MVPA: the correlations were 0.31 for the IPAQ-SF MVPA, 0.34 for the TPAQ MVPA and -0.29 for the DSI Inactivity scale. Nevertheless, none of the questionnaires can be used as a reliable individual-level estimate of MVPA in male adolescents. The boys underreported their MVPA in IPAQ-SF as compared to accelerometer-derived MVPA (respective averages 43 and 56 minutes); underreporting was more marked in active boys with average daily MVPA at least 60 minutes, and was not significant in less active boys. Conversely, MVPA index from TPAQ overestimated the MVPA in less active boys but underestimated it in more active boys. The sedentary time reported in IPAQ-SF was an underestimate as compared to accelerometer-derived sedentary time (averages 519 and 545 minutes, respectively). PMID:28056080

We describe current pubertal development in healthy urban Chinese boys. A cross-sectional study of the pubertal development of 18,807 urban Chinese boys aged from 3.50 to 18.49years was conducted between 2003 and 2005. Testicular volume was evaluated with a Prader orchidometer. Pubic hair development was assessed according to the Tanner method. Data on spermarche were collected using the status quo method. Probit analysis was used to calculate the median age and 95% CI at different stages of testicular development, pubic hair development and spermarche. By age 9, 12.99% of the boys had a testicular volume of 4mL or greater. The median age of onset of puberty defined as the age at attainment of testicular volume of 4mL or greater was 10.55 (95% CI 10.27-10.79) years. The median age for onset of pubic hair development (PH(2) ) and spermarche was 12.78 (95%CI 12.67-12.89) years and 14.05 (95%CI 13.80-14.32) years, respectively. Pubertal onset in urban Chinese boys is earlier than currently used clinical norms but their pubic hair development occurs relatively late in comparison with the reported data from numerous other countries. There is also evidence of a secular trend towards an earlier age of spermarche since 1979 in Chinese urban boys.

We describe a case of a boy with Von Hippel-Lindau disease who presented with recurrent right adrenal pheochromocytoma 4.5 years after laparoscopic bilateral partial adrenalectomy. The boy had a second laparoscopic adrenal-sparing removal of the tumor. By this technique, not only the recurrent tumor was successfully removed but also the unaffected adrenal cortex could be preserved for the second time. To our knowledge, this is the first published case of its type.

Gastric teratoma is very rare tumor and usually presents in early infancy. An 8-year-old boy presented with a huge mass in abdomen extending from epigastrium to the pelvis. Ultrasound and CT scan of abdomen revealed a huge mass with solid and cystic components and internal calcifications. The preoperative diagnosis was a teratoma but not specifically gastric one. At operation, it was found to be gastric teratoma. The mass was excised completely with part of the stomach wall. The histopathology confirmed it to be mature gastric teratoma. The rarity of the teratoma with delayed presentation prompted us to report the case. PMID:27900279

Naxos disease is a rare autosomal recessive form of arrhythmogenic right ventricular cardiomyopathy (ARVC) with woolly hair and palmoplantar keratoderma. The cardiomyopathy presents by adolescence with syncope, ventricular tachycardia (VT) of left bundle branch block (LBBB) morphology, and/or ventricular fibrillation. The diagnosis and management of ARVC are at present in evolution; the recently published modified Task Force Criteria for diagnosis and International Task Force consensus statement for treatment of ARVC will hopefully bring about uniformity in recognition and management of Naxos disease as well. Here, typical phenotype and diagnostic work up have been presented in a Bangladeshi boy with the Cardiocutaneous syndrome. PMID:27747171

Researchers are working to derive sperm from banked testicular tissue taken from pre-pubertal boys who face therapies or injuries that destroy sperm production. Success in deriving sperm from this tissue will help to preserve the option for these boys to have genetically related children later in life. For the twin moral reasons of preserving access and equity in regard to having such children, clinicians and researchers are justified in offering the option to the parents of all affected boys. However, some parents may wish to decline the option to bank tissue from their boys because the technique may seem too unfamiliar or unusual, but over time people may become more comfortable with the technique as they have done with other novel assisted reproductive treatments (ARTs). Other parents may wish to decline the option because of moral or religious reasons. A prominent natural law theory holds, for example, that the ARTs that would be involved in using sperm derived from banked tissue to produce a child are morally objectionable. Some parents might not want to bank tissue in order to shield their son from using ARTs they see as objectionable. Clinicians and researchers should respect parents who wish to decline banking tissue, but parents should ordinarily embrace choices that protect the possible interests their sons may have as adult men, including the wish to have genetically related children.

Context: The relationship between calcium (Ca) intake and Ca retention in adolescent boys was recently reported. Objective: This study evaluated the influence of Ca intake, serum hormone levels, biomarkers of bone metabolism, habitual physical activity, habitual Ca intake, and physical fitness on Ca retention in the same sample. Design: This study was a randomized, cross-over design that consisted of two 3-wk metabolic balance periods. Setting: The study took place on a university campus as a summer camp. Patients or Other Participants: A total of 31 American white boys (13–15 yr) participated in the study. Interventions: Each subject consumed a controlled diet with one of five high-low Ca intake pairs that ranged from 670-2003 mg/d, which was manipulated utilizing a fortified beverage. Main Outcome Measures: Ca retention was determined by Ca intake minus urinary and fecal Ca excretion during each balance period. Results: Ca intake explained 21.7% of the variability in Ca retention, and serum IGF-I concentration explained an additional 11.5%. Other serum hormone levels did not significantly add to the model. Biomarkers of bone metabolism, habitual physical activity, habitual Ca intake, and physical fitness were not significant predictors of Ca retention in adolescent boys. Conclusions: IGF-I, a regulator of growth during puberty, is an important predictor of Ca retention in adolescent boys. However, dietary Ca intake is an even greater predictor of Ca retention during this period of growth. PMID:18840643

The first 1000 days (conception to 24 months) is when gut microbiota composition and eating patterns are established, and a critical period influencing lifelong health. The aim of this study is to examine the associations between food intakes and microbiota composition at the end of this period. Diet was quantified for 37 well-nourished Australian children aged between 2 to 3 years by using a food frequency questionnaire and 24 hr recalls. Both dairy and plant-based (fruit, vegetables, soy, pulses and nuts) food intakes were associated with distinct microbiota profiles. Dairy intake was positively associated with the Firmicutes:Bacteroidetes ratio, and in particular Erysipelatoclostridium spp., but negatively associated with species richness and diversity. Vegetable intake was positively associated with the relative abundance of the Lachnospira genus, while soy, pulse and nut intake was positively associated with the relative abundance of bacteria related to Bacteroides xylanisolvens. Fruit intake, especially apples and pears, were negatively associated with the relative abundance of bacteria related to Ruminococcus gnavus. In this cohort of young children dairy and plant based food intakes were found to be associated with altered microbiota composition. Further exploration is needed to elucidate the effect of these dietary and microbial differences on host phenotype. PMID:27694811

The objective of this study was to examine whether social risk factors adjusted for gender and some well-known perinatal risk factors were related to parental descriptions of deviant behaviour in 3(1/2)-year-old children. The study was a prospective cohort study of 1345 mothers enrolled during early pregnancy. Parents answered a questionnaire and children's behavioural difficulties were categorized into the following groups; "hyperactive-distractible", "hostile-aggressive" and "anxious-fearful" following a modified Behar scale. The male gender was found to be related to a description of all kinds of deviant behaviour. Having a family member experiencing employment difficulties was the factor most closely related to "hyperactive-distractible" behaviour. Familial stress due to lack of time, experience of divorce and mothers in excess of 35 years at childbirth were found to be related to "hostile-aggressive" behaviour, but male gender was the most closely related. Social disadvantage was not found to be related to "anxious-fearful" behaviour.

Children's imitation of adults plays a prominent role in human cognitive development. However, few studies have investigated how children represent the complex structure of observed actions which underlies their imitation. We integrate theories of action segmentation, memory, and imitation to investigate whether children's event representation is organized according to veridical serial order or a higher level goal structure. Children were randomly assigned to learn novel event sequences either through interactive hands-on experience (Study 1) or via storybook (Study 2). Results demonstrate that children's representation of observed actions is organized according to higher level goals, even at the cost of representing the veridical temporal ordering of the sequence. We argue that prioritizing goal structure enhances event memory, and that this mental organization is a key mechanism of social-cognitive development in real-world, dynamic environments. It supports cultural learning and imitation in ecologically valid settings when social agents are multitasking and not demonstrating one isolated goal at a time.

PURPOSE Evidence from children's spontaneous speech suggests that utterance length and utterance position may help explain why children omit grammatical morphemes in some contexts but not others. This study investigated whether increased utterance length (hence, increased grammatical complexity) adversely affects children's third person singular -s production in more controlled experimental conditions. METHOD An elicited imitation task with 12 Australian English-speaking children ages 2;9 (years;months) to 3;2 (Mage = 2;11) was conducted comparing third person singular -s production in 3-word and 5-word utterances, both utterance medially (e.g., He sits back; He sits back and swings) and utterance finally (e.g., There he sits; That's the way he sits) using a within-subjects design. Children were shown pictorial representations of each utterance on a computer and were invited to repeat 16 pseudorandomized prerecorded utterances. Acoustic analysis determined the presence/absence and duration of the third person singular morpheme. RESULTS Third person singular production was significantly lower utterance medially compared to utterance finally for the 5-word utterances and significantly lower utterance medially in the 5-word compared to 3-word utterances. CONCLUSION These results suggest that increased utterance length results in significantly lower third person singular production, but only in the more articulatorily challenging utterance-medial position. Thus, morpheme omission is greatest at the intersection of grammatical and phonological complexity.

Although most countries recommend transitioning children from rear facing (RF) to forward facing (FF) child restraints at one year of age, Swedish data suggests that RF restraints are more effective. The objective of this study was to compare RF and FF orientations in frontal sled tests. Four dummies (CRABI 12 mo, Q1.5, Hybrid III 3 yr, and Q3) were used to represent children from 1 to 3 years of age. Restraint systems tested included both 1) LATCH and 2) rigid ISOFIX with support leg designs. Rear facing restraints with support legs provided the best results for all injury measures, while RF restraints in general provided the lowest chest displacements and neck loads.

We present two cases of wandering spleen, one in a 47-year-old woman who presented with constipation, and one in a 3-year-old girl who presented with acute abdominal pain. Wandering spleen is a rare clinical condition characterized by ectopic positioning of the spleen due to abnormal peritoneal attachments including the lienorenal and gastrosplenic ligaments. The spleen can "wander" or migrate into various positions within the abdomen or pelvis due to this ligamentous laxity. The clinical presentation of patients with this entity is variable and can range from an incidental finding to an acute abdomen associated with torsion. Various imaging modalities can be utilized for the diagnosis of this condition.

The bulk of the extant literature on the psychology of boys, men and masculinity has been focused on the important challenges of: a) creating an awareness about the detrimental effects of constricted forms of masculinity on boys and men and their relationships with others; and b) developing remedial approaches to psychotherapy that are designed to help boys and men recover from dysfunctional masculinity. The purpose of this article is to expand this literature by introducing the positive psychology/positive masculinity (PPPM) framework, which emphasizes male strengths as the starting point for psychotherapy with boys and men. The central principles of the PPPM framework are described, and the application of the PPPM model with an adult man in psychotherapy is presented. The implications of the PPPM model for future practice and research pertaining to boys, men, and masculinity are discussed.

We report on a 12 year old mentally retarded boy who presented at birth with bilateral knee dislocations, dislocation of the right hip, and general joint laxity. Cytogenetic studies showed a 49,XXXXY karyotype. Hyperlaxity of joints is known to occur in 49,XXXXY patients, but congenital knee dislocation has not been reported. Rarely in 49,XXXXY and 49,XXXXX syndromes Larsen-like features may be seen. Patients with congenital joint dislocation or laxity, combined with other malformations, especially if psychomotor development is delayed, should be karyotyped to exclude chromosomal abnormalities.

Autoimmune lymphoproliferative syndrome (ALPS) is an uncommon nonmalignant lymphoproliferative disease which is characterized by chronic, persistent or recurrent lymphadenopathy, splenomegaly, hepatomegaly, immune cytopenia , hypergammaglobinemia and increased risk of lymphoma. We report a 2-year old boy with hepatosplenomegaly as first presentation. Petechial and purpuric rashes with massive cervical lymphadenopathies developed 10 months later.In laboratory tests anemia, thrombocytopenia and hypergammaglobinemia were observed. According to flocytometry increased double negative T cells and by apoptosis assay decrease apoptosis of lymphocytes accompanied clinical manifestations, thus diagnosis of ALPS was established. In conclusion; in all patients with massive lymphadenopathy and hepatosplenomegay; especially with cytopenia; ALPS should be considered.

Pediatric scurvy is a rare condition characterized by perifollicular petechiae and bruising, hemorrhagic gingivitis and musculoskeletal symptoms, all assumed to be predominantly related to abnormal collagen structure. We report on a 9-year-old autistic boy with vitamin C deficiency due to a highly limited food range presenting with multiple petechiae, gum bleeding and debilitating bone pain, in whom platelet aggregometry revealed a distinctly reduced thrombocyte aggregation, normalizing after vitamin C supplementation. This observation indicates that platelet dysfunction may additionally contribute to the hemorrhagic diathesis in scurvy, and demonstrates that ascorbic acid deficiency should be considered in children with an otherwise unexplained acquired thrombocytopathy.

Upon ingestion, the artificial sweetener, aspartame is metabolized to formaldehyde in the body and has been reportedly associated with systemic contact dermatitis in patients exquisitely sensitive to formaldehyde. We present a case of a 9-year-old Caucasian boy with a history of mild atopic dermatitis that experienced severe systematized dermatitis after being started on montelukast chewable tablets containing aspartame. Patch testing revealed multiple chemical sensitivities which included a positive reaction to formaldehyde. Notably, resolution of his systemic dermatitis only occurred with discontinuation of the montelukast chewables.

Gifted girls and gifted boys are more alike than they are different, although researchers remain fascinated with sex differences. Small differences between gifted boys and girls in achievements, interests, careers, and relationships can become exaggerated through gendered educational practices. Kindergarten "red-shirting" of boys and the denial of…

Boys Town now operates satellite facilities for boys and girls in nine communities, as well as seven emergency shelters, a hospital, and a national hotline. (SLD)
The gender issue is relevant to classroom learning in more ways than one. Increasingly in the United States, young boys are saying that school is stupid and they do not like to read. This phenomenon cuts across all demographic groups: it affects affluent white boys in the suburbs no less than it affects black boys in low-income neighborhoods. In…
Noting that by 15 years of age, boys are three times more likely than girls to die from all causes combined, but especially from accidents, violence, and suicide, this book suggests that boys have special needs and offers suggestions for effective parenting.

Three studies examined the role of stereotype threat in boys' academic underachievement. Study 1 (children aged 4-10, n = 238) showed that girls from age 4 years and boys from age 7 years believed, and thought adults believed, that boys are academically inferior to girls. Study 2 manipulated stereotype threat, informing children aged 7-8 years (n = 162) that boys tend to do worse than girls at school. This manipulation hindered boys' performance on a reading, writing, and math test, but did not affect girls' performance. Study 3 counteracted stereotype threat, informing children aged 6-9 years (n = 184) that boys and girls were expected to perform similarly. This improved the performance of boys and did not affect that of girls.

The present case study investigates the effects of a cognitive training of verbal working memory that was proposed for Davide, a 14-year-old boy diagnosed with mild intellectual disability. The program stimulated attention, inhibition, switching, and the ability to engage either in verbal dual tasks or in producing inferences after the content of a short passage had been encoded in episodic memory. Key elements in our program included (1) core training of target cognitive mechanisms; (2) guided practice emphasizing concrete strategies to engage in exercises; and (3) a variable amount of adult support. The study explored whether such a complex program produced “near transfer” effects on an untrained dual task assessing verbal working memory and whether effects on this and other target cognitive mechanisms (i.e., attention, inhibition, and switching) were long-lasting and produced “far transfer” effects on cognitive flexibility. The effects of the intervention program were investigated with a research design consisting of four subsequent phases lasting 8 or 10 weeks, each preceded and followed by testing. There was a control condition (phase 1) in which the boy received, at home, a stimulation focused on the visuospatial domain. Subsequently, there were three experimental training phases, in which stimulation in the verbal domain was first focused on attention and inhibition (phase 2a), then on switching and simple working memory tasks (phase 2b), then on complex working memory tasks (phase 3). A battery of neuropsychological tests was administered before and after each training phase and 7 months after the conclusion of the intervention. The main finding was that Davide changed from being incapable of addressing the dual task request of the listening span test in the initial assessment to performing close to the normal limits of a 13-year-old boy in the follow-up assessment with this test, when he was 15 years old.

Yoga has been known to have stimulatory or inhibitory effects on the metabolic parameters and to be uncomplicated therapy for obesity. The purpose of the present study was to test the effect of an 8-week of yoga-asana training on body composition, lipid profile, and insulin resistance (IR) in obese adolescent boys. Twenty volunteers with body mass index (BMI) greater than the 95th percentile were randomly assigned to yoga (age 14.7±0.5 years, n=10) and control groups (age 14.6±1.0 years, n=10). The yoga group performed exercises three times per week at 40~60% of heart-rate reserve (HRR) for 8 weeks. IR was determined with the homeostasis model assessment of insulin resistance (HOMA-IR). After yoga training, body weight, BMI, fat mass (FM), and body fat % (BF %) were significantly decreased, and fat-free mass and basal metabolic rate were significantly increased than baseline values. FM and BF % were significantly improved in the yoga group compared with the control group (p<0.05). Total cholesterol (TC) was significantly decreased in the yoga group (p<0.01). HDL-cholesterol was decreased in both groups (p<0.05). No significant changes were observed between or within groups for triglycerides, LDL-cholesterol, glucose, insulin, and HOMA-IR. Our findings show that an 8-week of yoga training improves body composition and TC levels in obese adolescent boys, suggesting that yoga training may be effective in controlling some metabolic syndrome factors in obese adolescent boys.

Utilizing three classic films, and psychoanalytic developmental theory, this paper explores the conscious and unconscious reasons why older women become sexually involved with teenage boys. After a presentation of aspects of young adult and midlife female development and a psychodynamic explanation for the developmental similarities between adolescence and menopause, each of the three films is summarized. The dynamics behind the women's behavior, as presented in the films, are discussed. The third section of the paper discusses similarities and differences among the three women and the negative effects on the boys' development.

The hypothalamic-pituitary-adrenal (HPA) axis, including its regulation of cortisol, is central to bodily functioning and salivary cortisol is a commonly used biomarker that reflects the functioning of the HPA axis. However, knowledge of diurnal cortisol rhythms in healthy adolescents is limited and few studies have examined patterns in midadolescent girls and boys across single and aggregate cortisol measures. To fill this gap, the present study investigated single and aggregate cortisol measures reflecting diurnal rhythms in 14 to 16-year-old girls and boys. Self-administered salivary samples from 79 girls and 42 boys were collected during two schooldays at four timepoints: (a) immediately at awakening, (b) 30 min after waking up, (c) 60 min after waking up, and (d) at 8:00 p.m. Additionally, diary data including time of awakening, sampling times, and other potential confounders were analyzed. As for single measures, both girls and boys exhibited a typical diurnal cortisol profile with high levels in the morning that decreased throughout the day. However, girls had higher morning cortisol than did boys with significant differences at time of awakening, and at 30 and 60 min postawakening. For the aggregate measures, girls had a larger total level of cortisol in terms of cortisol awakening response (CARG ), area under the curve (AUCG ), and rise over run (slopeawake to last ), while no differences emerged for reactivity measures. Taken together, these findings suggest differences in single and aggregate cortisol measures between midadolescent girls and boys. Such differences in diurnal cortisol between pubertal girls and boys may play a role for the differential health trajectories typically found among adult women and men.

In order to gain insight into the functional and macroanatomical loci of visual selective processing deficits that may be basic to attention-deficit hyperactivity disorder (ADHD), the present study examined multi-channel event-related potentials (ERPs) recorded from 7- to 11-year-old boys clinically diagnosed as having ADHD (n=24) and age-matched healthy control boys (n=24) while they performed a visual (color) selective attention task. The spatio-temporal dynamics of several ERP components related to attention to color were characterized using topographic profile analysis, topographic mapping of the ERP and associated scalp current density distributions, and spatio-temporal source potential modeling. Boys with ADHD showed a lower target hit rate, a higher false-alarm rate, and a lower perceptual sensitivity than controls. Also, whereas color attention induced in the ERPs from controls a characteristic early frontally maximal selection positivity (FSP), ADHD boys displayed little or no FSP. Similarly, ADHD boys manifested P3b amplitude decrements that were partially lateralized (i.e., maximal at left temporal scalp locations) as well as affected by maturation. These results indicate that ADHD boys suffer from deficits at both relatively early (sensory) and late (semantic) levels of visual selective information processing. The data also support the hypothesis that the visual selective processing deficits observed in the ADHD boys originate from deficits in the strength of activation of a neural network comprising prefrontal and occipito-temporal brain regions. This network seems to be actively engaged during attention to color and may contain the major intracerebral generating sources of the associated scalp-recorded ERP components.

Pituitary adenomas are extremely rare in prepubescent children. Most of these tumors are functioning adenomas, but can also present with vision disturbances and changes in body morphology. We discuss the presentation, management, and outcome of a giant, solid, invasive prolactinoma in a 7-year-old boy who presented with visual disturbances and gynecomastia. The child demonstrated significant improvement in vision and a reduction in size of the tumor after subtotal tumor decompression and treatment with oral bromocriptine for 4 months. Tumor decompression and oral dopamine agonist therapy comprise the accepted treatment for pediatric prolactinomas. To our knowledge, only two previous reports described a giant prolactinoma in a prepubescent child. The relevant literature on pediatric pituitary tumours and prolactinoma is reviewed.

According to the internationally accepted classification, sexual maturation was investigated in 8685 healthy East German boys by means of the status quo method and the probit regression analysis. The 3rd, 50th and 97th centiles were calculated for the development of both the male external genitalia and pubic and axillary hairs. The findings are in line with those of recent studies from different European countries. Special attention was paid to the stages at the beginning and at the end of sexual maturation, e.g. B 2, B 5; AH2, AH3; PH 2, PH5/6, etc.

This study compared attributions for child behavior among mothers of 38 nonproblem boys, 26 boys with attention deficit hyperactivity disorder (ADHD), and 25 boys with ADHD and oppositional defiant (OD) behavior. Boys ranged from 7 to 10 years of age. To capture different aspects of mothers' attributions, 2 assessment methods were employed: (a) ratings of the internality, controllability, globality, and stability of causes for written descriptions of child behavior and (b) coding of the types of causal attributions that mothers provided in vivo while watching their own child's behavior. In response to the written descriptions of child behavior, mothers of boys with ADHD/OD rated the causes of oppositional and inattentive-impulsive child behaviors as more stable and global than did mothers of nonproblem boys. In identifying causes of their own child's failure on lab tasks, mothers of boys with ADHD/OD provided more child-negative attributional causes than did mothers of either ADHD only or nonproblem boys. Implications for assessing and understanding attributions in families of children with ADHD and OD are discussed.

Background Repetitive behaviours are frequently observed in individuals with intellectual disability. The present study examined the profile, inter-correlations, and predictive correlates of repetitive behaviours in males with FXS, the leading inherited cause of intellectual disability. Specific child characteristics examined as predictors included: anxiety, nonverbal cognition, and autism social-affective symptomatology. Method Participants were 39 boys with FXS (aged 6–10 years). Repetitive behaviours were measured using the Repetitive Behavior Scale – Revised (RBS-R) – a 43-item caregiver-report measure normed on individuals with intellectual disability. Results Restricted Interests and Sensory Motor behaviours were reported as most problematic for this sample of boys, whereas Self-injurious behaviours were less problematic. All subscales of the RBS-R were significantly inter-correlated. Nonverbal IQ was negatively related, whereas anxiety and social affective symptoms of ASD were positively related, to scores for Restricted Interests. Anxiety was also positively related to scores for Compulsive behaviours and Ritualistic Sameness behaviours. Conclusions This study provides a preliminary description of repetitive behaviours in males with FXS, which may form the groundwork for future research. PMID:26449367

In work done at the German Criminological Research Institute of Lower Saxony (KFN) various methods have been used to investigate how specific inappropriate media usage patterns affect academic performance in children and adolescents. The findings are paralleled by current international research indicating a negative relationship between these two variables. Based on a cross-sectional survey of 5,529 fourth grade students and a longitudinal panel study with 1,157 primary schoolchildren, a key finding can be demonstrated: the more time students spend on consuming media and the more violent its contents are, the worse are their marks at school, even when controlling for vital factors such as family, educational, or immigrant background. In particular, boys who gender-specifically are better equipped with electronic media devices, who partially have extensive media usage times and who strongly prefer violent media content, are at the risk of showing poor school performance. In fact, a decrease in academic performance of boys can be observed in German school statistics. By presenting first results of a school-based intervention programme, a promising approach to the reduction of detrimental effects of electronic media use on school performance is introduced.

The present study examines verbal working memory over time in boys with fragile X syndrome (FXS) compared to nonverbal mental-age (NVMA) matched, typically developing (TD) boys. Concomitantly, the relationship between cortisol-a physiological marker for stress-and verbal working memory performance over time is examined to understand the role of physiological mechanisms in cognitive development in FXS. Participants were assessed between one and three times over a 2-year time frame using two verbal working memory tests that differ in complexity: memory for words and auditory working memory with salivary cortisol collected at the beginning and end of each assessment. Multilevel modeling results indicate specific deficits over time on the memory for words task in boys with FXS compared to TD controls that is exacerbated by elevated baseline cortisol. Similar increasing rates of growth over time were observed for boys with FXS and TD controls on the more complex auditory working memory task, but only boys with FXS displayed an association of increased baseline cortisol and lower performance. This study highlights the benefit of investigations of how dynamic biological and cognitive factors interact and influence cognitive development over time.

The aim of the present study was to examine the association between sociocultural influences to attain an ideal body and body change strategies (BCS) in Spanish adolescent boys of different weight status. A total of 594 Spanish boys (M=13.94 years, SD=0.20) participated. Measures included in the study were weight status according to body mass index (BMI), sociocultural influences (perceived pressures to attain an ideal body, general internalization of an ideal body, internalization of an athletic-ideal body), BCS to lose/control weight (dieting, healthy and unhealthy weight-control behaviors), and BCS to gain weight and muscles. Underweight boys engaged more frequently in weight-gain behaviors. Overweight boys reported higher levels of perceived sociocultural pressures and general internalization compared to normal-weight boys, and were more likely to be engaged in BCS to lose/control weight compared with the other weight-status groups. There were no differences between groups in terms of internalization of an athletic-ideal body and BCS to increase muscles. Future research and prevention programs should consider male-specific behaviors and weight-status differences.

Prenatal cocaine exposure may affect developing stress response systems in youth, potentially creating risk for substance use in adolescence. Further, pathways from prenatal risk to future substance use may differ for girls versus boys. The present longitudinal study examined multiple biobehavioral measures, including heart rate, blood pressure, emotion, and salivary cortisol and salivary alpha amylase (sAA), in response to a stressor in 193 low-income 14- to 17-year-olds, half of whom were prenatally cocaine exposed (PCE). Youth’s lifetime substance use was assessed with self-report, interview, and urine toxicology/breathalyzer at Time 1 and at Time 2 (6–12 months later). PCExGender interactions were found predicting anxiety, anger, and sadness responses to the stressor, with PCE girls showing heightened responses as compared to PCE boys on these indicators. Stress Response × Gender interactions were found predicting Time 2 substance use in youth (controlling for Time 1 use) for sAA and sadness; for girls, heightened sadness responses predicted substance use, but for boys, dampened sAA responses predicted substance use. Findings suggest distinct biobehavioral stress response risk profiles for boys and girls, with heightened arousal for girls and blunted arousal for boys associated with prenatal risk and future substance use outcomes.

Boys have a slight advantage in the number of live births in the US (about 101:100), so, all things being equal, it is reasonable to assume that they would populate institutions at about the same rate as girls. However, institutions are social structures, and in social systems all things are almost "never" equal, so, clearly, there are other…

To highlight a rare disease like multiple endocrine neoplasia (MEN)-2B variant of medullary thyroid carcinoma and to optimize the management option in such cases, we present a nine year old boy with thyroid swelling, cervical lymphadenopathy and thick lips. His calcitonin level was raised. Investigation's results of the boy were as following fine needle aspiration cytology (FNAC) was medullary carcinoma of thyroid, preoperative calcitonin was >2000pg/ml, post operative histopathological report was medullary carcinoma. Total thyroidectomy with aggressive initial neck surgery may reduce the recurrence and increase better prognosis and survival rate. Calcitonin is used as diagnostic and follow-up marker.

This study presents descriptive findings from in-depth interviews with 29 representatives of organizations in Africa, Asia, Europe, Oceania, and North and South America that engage men and boys in preventing gender-based violence. In particular, the findings suggest that strategies are responsive to the specific cultural, economic, and contextual concerns of the local community, with nuanced messages and appropriate messengers. In addition, respondents reported key principles informing their organizational strategies to deepen men and boys' engagement. Attention is also paid to respondents' caution about the risks of framing of engagement practices as separate from both women's organizations and women and girls themselves.

Background The first aim of the present study was to investigate differences in correlates of vegetable intake between the normal weight and the overweight boys in the Pro Children Cross Sectional Study. The second aim was to explore whether the association between vegetable intake and potential correlates is different in overweight boys compared with normal weight boys. Methods Random samples of mainly 11-year old children were recruited in 9 European countries. The total sample size consisted of 3960 boys (16.5% overweight). A validated self-report questionnaire was used to measure vegetable intake, and personal, social and environmental factors related to vegetable intake in the classroom. Weight and height were reported by the parents of the children in parents' questionnaires. Results Regression analyses explained 23% to 28% of the variance in vegetable intake by potential correlates. Liking, self-efficacy and bringing vegetables to school were related to intake in both normal weight and overweight boys (β's>0.10). Active parental encouragement and availability at home was only related to intake in overweight boys (β's>0.10), whereas knowledge about recommendations was only related to vegetable consumption in normal weight boys (β>0.10) Conclusion Intervention strategies to increase vegetable intake should focus on increase in liking and preferences, increase in self-efficacy, and increase in bringing vegetables to school in both normal weight and overweight boys. Further research should investigate whether advising parents of overweight boys to encourage their child to eat vegetables every day, to insist as far as possible that their child eats vegetables regularly and to make vegetables easily available at home is effective in changing vegetable intake.

This study investigated geology knowledge acquisition by Boy Scouts through use of the Boy Scout Geology Merit Handbook. In this study, boys engaged in hands-on interactive learning following the requirements set forth in the Geology Merit Badge Handbook. The purposes of this study were to determine the amount of geology content knowledge engendered in adolescent males through the use of the Geology Merit Badge Handbook published by the Boy Scouts of America; to determine if single sex, activity oriented, free-choice learning programs can be effective in promoting knowledge development in young males; and to determine if boys participating in the Scouting program believed their participation helped them succeed in school. Members of a local Boy Scout Troop between the ages of 11 and 18 were invited to participate in a Geology Merit Badge program. Boys who did not already possess the badge were allowed to self-select participation. The boys' content knowledge of geology, rocks, and minerals was pre- and post-tested. Boys were interviewed about their school and Scouting experiences; whether they believed their Scouting experiences and work in Merit Badges contributed to their success in school. Contributing educational theories included single-sex education, informal education with free-choice learning, learning styles, hands-on activities, and the social cognitive theory concept of self-efficacy. Boys who completed this study seemed to possess a greater knowledge of geology than they obtained in school. If boys who complete the Boy Scout Geology Merit Badge receive additional geological training, their field experiences and knowledge acquired through this learning experience will be beneficial, and a basis for continued scaffolding of geologic knowledge.

Purpose Previous research suggests that language comprehension might be particularly impaired in children with autism spectrum disorder (ASD), but this profile has been only broadly characterized. The current study examined sentence comprehension in school-age boys with ASD, including a subgroup with intellectual disability, with particular attention to errors that might differentiate between lexically and syntactically based difficulties. Method Participants were boys with ASD (n = 45; ages 4 – 11 years) and younger typically developing boys (n = 45; ages 2 – 6 years). Comprehension was assessed with the Test for Reception of Grammar-2 (TROG-2). Error types were analyzed for a subset of items. Results Boys with ASD did not differ from younger typically developing boys matched on receptive vocabulary in overall sentence comprehension on the TROG-2 or the number of lexical errors committed. In contrast, the subgroup of boys with ASD and intellectual disability (n = 16) had poorer overall performance and committed more lexical errors than younger typically developing boys matched on nonverbal cognition. Conclusions On average, comprehension is delayed in school-age boys with ASD, but not beyond receptive vocabulary expectations. Boys with ASD and intellectual disability, however, have a weakness in sentence comprehension beyond nonverbal cognitive-expectations. PMID:24687049

A 7-year-old boy presented with an annular verrucous plaque on the chin of 5 weeks duration. The lesion occurred after a bicycle accident and was unresponsive to antibiotics. Fungal culture grew Sporothrix schenckii. Sporotrichosis should be considered and fungal culture obtained whenever a nodule or plaque fails to respond to initial treatment.
This paper considers how "knowledge" of China was presented for Victorian and Edwardian children in "The Boy's Own Paper" ("BOP") between 1879 and 1914.

Background Feeding problems are common in boys with Barth syndrome and may contribute to the population’s propensity for growth delay and muscle weakness. The purpose of this study was to quantify and describe these feeding issues and examine altered taste perception and sensory sensitivity as contributing factors. Methodology A cross-sectional, two-group comparison design was used to examine feeding preferences and behaviors, chemical taste perception, and sensory sensitivities in fifty boys with (n=24) and without (n=26) Barth ages 4–17 years. Taste perception was measured using chemical test strips saturated with phenylthiocarbamide (PTC) and sodium benzoate (NaB). Feeding problems were documented by parents using a Food Inventory, while sensory sensitivities were recorded using a Short Sensory Profile. Results Boys with Barth differed significantly from typical peers with regards to problem feeding behaviors. For boys with Barth, food refusal and food selectivity were identified as being present in 50% the sample, while 70% of had identified problems related to gagging or swallowing foods. About half of all Barth families noted that their child’s eating habits did not match the family’s and that separate meals were often prepared. As demonstrated in previous research, about 50% of boys with Barth demonstrated probable or definite differences in taste/smell sensitivity, which was significantly higher than controls. On tests of chemical taste perception, boys with Barth were significantly more likely to be supertasters to PTC and non-tasters to NaB. Taster-status did not directly relate to the presence of feeding problems, however, taste/smell sensitivity did significantly relate to food selectivity by type and texture. Conclusions Results indicate feeding problems in at least 50–70% of boys with Barth syndrome, and suggest that behaviors are often present before 6 months of age. Differences in taste perception may influence dietary choices in boys with

The current paper reports of language production in 15 Hebrew-speaking boys, aged 9;0-13;0, with fully methylated, non-mosaic fragile X syndrome and no concomitant diagnosis of autism. Contrary to expectations, seven children were non-verbal. Language production in the verbal children was studied in free conversations and in context-bound speech. Despite extra caution in calculating MLU, participants' language level was not predicted by mean utterance length. Context bound speech resulted in grammatically more advanced performance than free conversation, and performance in both contexts differed in important ways from performance of typically developing MLU-matched controls. The relevance of MLU as a predictor of productive grammar in disordered populations is briefly discussed.

The Boy Scouts of America National Executive Board (BSA) recently changed its longstanding policy of excluding gay youth up to the age of 18. Gay participants of its coed Venturing program would be allowed to be members until the age of 21. However, lesbians and homosexuals are still not permitted to be troop leaders. This article discusses the evolution of the change in BSA's policy, discusses the timeline of other proposals in regard to BSA's acceptance of gay youth, and suggests that changes in public opinion and the reaction of BSAs stakeholders lead to changes in the BSA policy. The BSA made a change to become more compatible with the environment in which it operates.

Low triiodothyronine syndrome is a physiological adaptation encountered in anorexia nervosa (AN) and generally improves with sufficient weight gain. However, when a primary thyroid pathology accompanies AN, both the evaluation of thyroid hormone levels and the management of the co-morbid disease become more challenging. Hashimoto thyroiditis could complicate the management of AN by causing hyper- or hypothyroidism. AN could also negatively affect the treatment of Hashimoto thyroiditis by altering body weight and metabolic rate, as well as by causing drug non-compliance. We present the case of a 15-year-old boy with comorbid AN restrictive sub-type and Hashimoto thyroiditis. In this case report, we aimed to draw attention to the challenges that could be encountered in the diagnosis, treatment, and follow-up of patients with AN when accompanied by Hashimoto thyroiditis.

Although Klinefelter's syndrome is the most common sex chromosome anomaly, affecting one in 5-800 boys, our knowledge of the syndrome is still poor. This is reflected in the paucity of published literature as compared, for example, with the vastly greater number of publications on Turner's syndrome with its lower incidence of 1/2,500 girls. Klinefelter's syndrome is manifestly underdiagnosed. Existing knowledge mainly derives from cases characterised by prominent symptomatology. Early diagnosis is important if additional support and resources are to be made available to the patient and his family. Testosterone replacement therapy should be initiated as soon as clinical and laboratory evidence becomes available. In selected cases, testosterone treatment can be started already during adolescence. At present, there is no established treatment for the infertility which almost always accompanies the condition.

Pyoderma gangrenosum (PG) is an uncommon, chronic ulcerative condition of the skin that was first described in 1930. It can occur in any age group, but only 4% of the patients are infants or children. An underlying systemic disease is present in approximately 50% of the patients with PG. The most common associations include inflammatory bowel disease, arthritis, lymphoproliferative disorders and chronic recurrent multifocal osteomyelitis (CRMO). PG has been reported in association with CRMO in only a few children whose ages were between 18 months and 12 years. We report a six-month-old boy who was diagnosed as CRMO based on his clinical examination and histological findings. This is the youngest case reported in the literature (under 12 months of age) with PG associated with CRMO.

Young men with superior upper-body strength typically show a greater proclivity for physical aggression. The traditional interpretation is that young men calibrate their attitudes and behaviors to their physical formidability. Physical strength is thus viewed as a causal antecedent of aggressive behavior. The present study is the first to examine this phenomenon within a developmental framework. We demonstrate that males' antisocial tendencies temporally precede their physical formidability. We capitalize on the fact that physical strength is a male secondary sex characteristic. In two longitudinal cohorts of children, we estimate adolescent change in upper-body strength using the “slope” parameter from a latent growth model. Boys, but not girls, with greater antisocial tendencies in childhood attained larger increases in physical strength between the ages of 11 and 17. These results support sexual selection theory, indicating an adaptive congruence between male-typical behavioral dispositions and subsequent physical masculinization during puberty. PMID:25717041

Summary Dent disease is a rare X-linked recessive proximal tubular disorder that affects mostly male patients in childhood or early adult life. Dent disease is clinically characterized by the presence of low molecular weight proteinuria (LMWP), hypercalciuria, medullary nephrocalcinosis, nephrolithiasis, and progressive renal failure. The clinical features, diagnosis, and treatment of Dent disease were examined in 10 Chinese boys. All 10 childhood cases of Dent disease in China presented with tubular proteinuria in the nephrotic range and hypercalciuria. The ratio of α1-microglobulinuria to microalbuminuria, if close to or above 1, can be used as a diagnostic criterion for tubuloproteinuria. Lotensin was ineffective at treating proteinuria while dihydrochlorothiazide reduced urine calcium excretion. PMID:28357180

Children׳s perception of prosodic phrasing provides a head start into the discovery of speech structure. Based on the close prosody-syntax correspondence, children can infer the underlying syntactic structure from the acoustic modulations of prosodic boundaries, typically consisting of co-occurring pitch changes, preboundary lengthening, and pausing. Previous electrophysiological studies revealed that listeners are to some degree flexible in the detection of major prosodic boundaries that are not marked with all three of the suprasegmental cues. Adults and 6-year-olds still showed the brain response for prosodic boundary perception, the Closure Positive Shift (CPS), when pauses marking boundaries were deleted. In contrast, younger children at 3 years did not show this ability yet, but required pausing to complement the other boundary cues. Following the hypothesis that German weights duration cues more heavily than pitch cues, we here examined 3-year-olds׳ brain responses to prosodic phrasing, testing the role of boundary-related pitch changes. Results revealed that children at this age even showed the CPS in response to pitch-neutralized boundaries with only pausing and preboundary lengthening being present. These results indicate differential roles of acoustic cues in boundary perception, with a preferential reliance on duration cues over pitch changes in 3-year-olds. This preference likely results from the characteristics of the German intonation system and furthers the discussion of cross-linguistic differences in the weighting of prosodic boundary cues.

A moral panic has broken out in several countries after recent studies showed that girls were outperforming boys in education. Commissioned by the Dutch Ministry of Education, the present study examines the position of boys and girls in Dutch primary education and in the first phase of secondary education over the past ten to fifteen years. On the basis of several national and international large-scale databases, the authors examined whether one can indeed speak of a gender gap, at the expense of boys. Three domains were investigated, namely cognitive competencies, non-cognitive competencies, and school career features. The results as expressed in effect sizes show that there are hardly any differences with regard to language and mathematics proficiency. However, the position of boys in terms of educational level and attitudes and behaviour is much more unfavourable than that of girls. Girls, on the other hand, score more unfavourably with regard to sector and subject choice. While the present situation in general does not differ very much from that of a decade ago, it is difficult to predict in what way the balances might shift in the years to come.

This study describes the amount of physical activity and perception of physical activity in boys with Duchenne muscular dystrophy (DMD) compared to healthy boys. A questionnaire described 6 domains of physical activity. Four Duchenne muscular dystrophy subgroups were made: early and late ambulatory, nonambulatory with relative good, or limited arm function. Eighty-four boys with Duchenne muscular dystrophy (15.0 ± 6.4 years) and 198 healthy boys (14.0 ± 4.3 years) participated. Daily activities were more passive for boys with Duchenne muscular dystrophy. Physical activity was less and low demanding compared to healthy boys. It decreased with disease severity ( P < .05), whereas screen time increased ( P < .05). Benefits of physical activity in boys with Duchenne muscular dystrophy were having fun and making friends. Barriers were lack of sport facilities and insufficient health. This study helps to quantify poor engagement in physical activity by boys with Duchenne muscular dystrophy, and demonstrates factors that contribute to it. Suggestions to stimulate physical activity are made.

The purpose of this study was to examine the effect of peer monitoring on generosity in boys and girls aged 6–12 years. A total of 120 elementary school students played a one-shot dictator game (DG) with and without peer monitoring by classmates. Children decided how to divide 10 chocolates between themselves and a classmate either in a condition in which their allocations were visible to their peers, or in private. While the effect of peer monitoring on the allocation amount in the DG was clearly present in boys, it was not observed in girls. Furthermore, the effect of peer monitoring in boys appeared at the age of 9 years. These results suggest that the motivation to draw peers’ attention plays a stronger role for older boys than for girls or younger boys. The potential roles of higher-order theory of mind, social roles, and emergence of secondary sex characteristics on the influence of peer monitoring on generosity shown by boys are discussed.

The figpurpose of this study was to investigate the evaluation of differences in morphological qualities in physical strength of South Korean junior high school boys. The subjects were 201 first-year junior high school boys (13.6 +/- 0.3 years, 59.0 +/- 12.8 kg, 163.1 +/- 7.4 cm, in whom height, weight, BMI, fat mass, body fat percentage and soft lean mass were measured. Items of physical strength measured were the sit and reach, 20-m shuttle run, push-ups, and sit-ups. Morphological quality was judged from two aspects, a BMI evaluation of obesity or leanness and an evaluation of the level of fat accumulation derived from regression polynomials of body fat percentage against BMI. The subjects were classified into 9 groups according to differences in morphological quality. Of the physical measurement items, boys with underdevelopment of fat in the BMI slim and normal groups showed superior results in the 20-m shuttle run, push-ups and sit-ups. In contrast, boys with overdevelopment of fat in the BMI fatty group showed significantly poorer results in these items. Meanwhile, boys with underdevelopment of fat in the BMI fatty group showed a level comparable to boys in the BMI normal and excessive fat groups in the 20-m shuttle run; boys with normal and excessive fat in the BMI normal group and boys with excessive fat in the BMI slim group in push-ups; and boys with underdevelopment of fat in the BMI slim group in sit-ups. Performance in these measurements was evaluated in detail for boys with different morphological qualities, and multiple considerations from the two aspects of physique and physical composition may be necessary to evaluate the physical strength of students in each grade.

The challenge of violence for youth in low-income countries includes a range of experiences from witnessing, to experiencing, to participating in violence. Although boys and young men are often the perpetrators of such violence, they may also be its victims. Yet little evidence exists from the voiced experiences of boys themselves on perceptions and interpretations of the violence around them. Given the numerous negative health implications of violence for boys, for the girls and other boys with whom they interact, and for the health of their future partners and families, we conducted an in-depth study in rural and urban Tanzania with adolescent boys on the masculinity norms shaping their transitions through puberty that might be contributing to high-risk behaviours, including engagement in violence. The findings identified underlying societal gendered norms influencing the enactment of violence, and recommendations from the boys on how to diminish the violence around them. Additional research is needed with boys on the social norms and structural factors influencing their engagement in violence.

Introduction The Phillips Report on traumatic brain injury (TBI) in Ireland found that injury was more frequent in men and that gender differences were present in childhood. This study determined when gender differences emerge and examined the effect of gender on the mechanism of injury, injury type and severity and outcome. Methods A national prospective, observational study was conducted over a 2-year period. All patients under 17 years of age referred to a neurosurgical service following TBI were included. Data on patient demographics, events surrounding injury, injury type and severity, patient management and outcome were collected from ‘on-call’ logbooks and neurosurgical admissions records. Results 342 patients were included. Falls were the leading cause of injury for both sexes. Boys’ injuries tended to involve greater energy transfer and involved more risk-prone behaviour resulting in a higher rate of other (non-brain) injury and a higher mortality rate. Intentional injury occurred only in boys. While injury severity was similar for boys and girls, significant gender differences in injury type were present; extradural haematomas were significantly higher in boys (p=0.014) and subdural haematomas were significantly higher in girls (p=0.011). Mortality was 1.8% for girls and 4.3% for boys. Conclusions Falls were responsible for most TBI, the home is the most common place of injury and non-operable TBI was common. These findings relate to all children. Significant gender differences exist from infancy. Boys sustained injuries associated with a greater energy transfer, were less likely to use protective devices and more likely to be injured deliberately. This results in a different pattern of injury, higher levels of associated injury and a higher mortality rate. PMID:22962053

Chronic granulomatous disease (CGD) is a rare, polygenic primary immunodeficiency. In this case report, we describe a previously healthy 13-year-old boy who presented with multifocal pulmonary aspergillosis and was subsequently diagnosed with an autosomal recessive form of chronic granulomatous disease. CGD has a variable natural history and age of presentation and should be considered when investigating a patient with recurrent or severe infections with catalase-positive organisms. PMID:27445540

In utero and during the first 5 years of life, boys face unique risks as a result of neurobiological and environmental factors. This introductory article to the Special Issue describes the background of this gender-specific inquiry and outlines some of those risks, drawing attention to the areas that will be covered in depth in the following contributions. We also describe the basis of this inquiry as the link between early life and the subsequent difficulties that adolescent boys and many young men face, and pay particular attention to the circumstances of young men of color and to the growing knowledge about the contributions of fathers to boys' development.

We report on 2 patients with congenital insensitivity to pain and anhydrosis. The first one was a 7-month-old boy who presented with non-traumatic, haematogenous septic dislocation of the right elbow with physeal separation of the distal humerus. The second one was a 3-year-old girl suspected to have Job syndrome with an altered immunological profile.

This case report presents a classical case of nodular scabies in a 12 year boy who complained of itching for 20-21 days before presentation to the hospital. Application of Betnovate ointment (Betamethasone valerate 0.1 %) before presentation to the hospital had provided only 2-3 days of relief from itching. Dermatological examination revealed skin colored to erythematous papule of 3-4 mm on the body with predilection for web space of fingers and flexural areas and nodules on the scrotum and groin. Based on this, clinical diagnosis of scabies with nodular scabies was made on the child. The scraping obtained from the web-space of the child showed mite under the light microscope, which confirms the diagnosis. Treatment with topical permethrin 5 % lotion resulted in 50-70 % subsidence of itching within a day, and improvement in impetigo lesions of his father in 5 days. However, the scrotal and groin nodular lesion of the child persisted with severe itching. Treatment with topical steroid and tacrolimus 0.1 % ointment did not show much improvement. Intralesional injection of triamcinolone (5 mg/ml) on the nodule resulted in 30-40 % subsidence in itching and 50-60 % reduction in the size of the lesion over 2-3 weeks.

Paintball is a popular recreational sport played by 3.655 million Americans and may be sufficient physical activity to promote health. Paintball has been played as an organized sport since the 1980’s and is essentially a game of tag, except instead of touching an opponent by hand opponents are tagged by shooting them with a paintball that leaves a mark indicating who has been eliminated. A previous evaluation of paintball as physical activity had 13 subjects undergo a VO2max test to develop a heart rate (HR) /oxygen consumption relationship, and it was observed that heart rates during paintball were 68–73% of the measured maximal HR. The present study used accelerometry and HR monitors to evaluate the quantity and intensity of physical activity in boys playing paintball. Eleven boys (12.7 ± 1.0 y, 51.5 ± 11.3 kg, 161.8 ± 10.1 cm) engaged in a VO2max test to develop a HR/oxygen consumption correlation. On a separate day the boys played 7 games of outdoor paintball while wearing a HR monitor and accelerometer. The boys played paintball for 11.5 ± 6.2 minutes/game for a total of 80.6 ± 10.0 minutes of game play. Average HR during paintball play was 129.6 ± 6.6 beats/min, representing 39.9 ± 12.9% VO2max. Based on accelerometry, the boys accumulated 63.2 ± 15.6 minutes of moderate intensity activity and 2.6 ± 2.8 minutes of vigorous activity during paintball. These data suggest that playing paintball may be considered as physical activity that is > 3 METs, and thus health promoting. PMID:27182396

Observation of 18 three-year-old boys revealed that they reacted more positively to both of their parents when their play style was more physical and active, resembling the typical paternal style. (Author/BJV)
This article provides insight and understanding into important issues of which nurses need to be aware when caring for men and boys with regard to their mental health. Inequalities in health care are discussed, and suggestions made concerning how all nurses can help redress these inequalities. The mental health of men and boys concerns all nurses; not just those working in mental health settings. The article focuses on a recent review published by the Men's Health Forum (Wilkins, 2010), and considers a number of gender-specific mental health issues that affect the health and wellbeing of men and boys. The role of the nurse is to protect and promote the health of people in their care and this article makes clear that this extends to and includes the mental health of men and boys. Labelling people and categorizing them into homogenous groups is not often helpful or strategically wise; this article does not wish to categorize, but merely attempts to explain.

This study of science education in the Boy Scouts of America focused on males with Boy Scout experience. The mixed-methods study topics included: merit badge standards compared with National Science Education Standards, Scout responses to open-ended survey questions, the learning styles of Scouts, a quantitative assessment of science content knowledge acquisition using the Geology merit badge, and a qualitative analysis of interview responses of Scouts, Scout leaders, and scientists who were Scouts. The merit badge requirements of the 121 current merit badges were mapped onto the National Science Education Standards: 103 badges (85.12%) had at least one requirement meeting the National Science Education Standards. In 2007, Scouts earned 1,628,500 merit badges with at least one science requirement, including 72,279 Environmental Science merit badges. "Camping" was the "favorite thing about Scouts" for 54.4% of the boys who completed the survey. When combined with other outdoor activities, what 72.5% of the boys liked best about Boy Scouts involved outdoor activity. The learning styles of Scouts tend to include tactile and/or visual elements. Scouts were more global and integrated than analytical in their thinking patterns; they also had a significant intake element in their learning style. Earning a Geology merit badge at any location resulted in a significant gain of content knowledge; the combined treatment groups for all location types had a 9.13% gain in content knowledge. The amount of content knowledge acquired through the merit badge program varied with location; boys earning the Geology merit badge at summer camp or working as a troop with a merit badge counselor tended to acquire more geology content knowledge than boys earning the merit badge at a one-day event. Boys retained the content knowledge learned while earning the merit badge. Scientists, Scout leaders, and Scouts felt that Scouts learned science through participation in the Boy Scout program

Possible differences in the growth of boys of four language groups were investigated by anthropometric measurements in a sample of 582 boys of documented age from a Hyderabad school. Correlation of all body measurements with age was sufficiently close over the age range studied to allow linear regressions on age to be fitted. Covariance analysis suggested a difference in trunk length, with Telugu speakers having longer trunks than the other language groups, both absolutely and after stature was taken into account.
