Craniofacial morphology and otitis media with effusion in children

Otitis media with effusion (OME) affects 28-38% of pre-school children, and it occurs due to the dysfunction of the auditory tube. Anatomical development of the auditory tube depends on the craniofacial growth and development. Deviations of normal. craniofacial. morphology and growth using cephatometric studies, may predict the evolution of otitis. Our goal in this paper is to determine if there are differences in craniofacial morphology between children with adenoid enlargement, with and without otitis media with effusion. This is a prospective study in which the sample consisted of 67 children (mate and female) from 5 to 10 years old. All patients presented chronic upper airway obstruction due to tonsil. and adenoid enlargement (>80% degree of obstruction). Thirty-three patients presented otitis media with effusion, for more than 3 months and 34 did not. The tatter composed the control group. Standardized lateral head radiographs were obtained for all. subjects. Radiographs were taken with patient positioned by a cephalostat and stayed with mandibles in centric occlusion and Lips at rest. Radiographs were digitalized and specific Landmarks were identified using a computer program Radiocef 2003, 5th edition. Measurements, angles and tines were taken of the basicranium, maxilla and mandible according to the modified Ricketts analysis. In addition, facial height and facial axis were determined. Children with otitis media with effusion present differences in the morphology of the face, regarding these measures: N-S (anterior cranial base length), N-ANS (upper facial height), ANS-PNS (size of the hard palate), Po-Or.N-Pog (facial depth), Ba-N.Ptm-Gn (facial axis), Go-Me (mandibular Length) and Vaia--Vaip (inferior pharyngeal airway).

Long-term follow-up of children with extrahepatic portal vein obstruction: impact of an endoscopic sclerotherapy program on bleeding episodes, hepatic function, hypersplenism, and mortality

Background: Endoscopic sclerotherapy (ES) has been the standard treatment for children with idiopathic extrahepatic portal vein obstruction (EHPVO). Portosystemic shunts are indicated when variceal bleeding cannot be controlled by ES. Recently, mesenteric left portal vein bypass was indicated as a surgical intervention and preventative measure for hepatic dysfunction in children with long-term EHPVO. Nevertheless, there is a lack Of published data confirming the extent of hepatic dysfunction, hypersplenism, and physical development in children with long-term follow-up. Method: We retrospectively verified the long-term outcomes in 82 children with EHPVO treated with ES protocol, focusing on mortality, control of bleeding, hypersplenism, and consequent hepatic dysfunction. Results: Of the children, 56% were free from bleeding after the initiation of ES. The most frequent cause of rebleeding was gastric varices (30%). Four patients had recurrent bleeding from esophageal varices (4.6%). Four patients underwent surgery as a consequence of uncontrolled gastric varices. There were no deaths. Most patients showed good physical development. We observed a mild but statistically significant drop in factor V motion, as well as leukocyte and platelet count. Conclusion: Endoscopic sclerotherapy is an efficient treatment for children with EHPVO. The incidence of rebleeding is low, and there was no mortality. Children develop mild liver dysfunction and hypersplenism with long-term follow-up. Only a few patients manifest symptoms of hypersplenism, portal biliopathy, or liver dysfunction before adolescence.

Early diagnostic and endoscopic dilatation for the treatment of acquired upper airway stenosis after intubation in children

Background: Upper airway stenosis (UAS) after endotracheal intubation is a common problem in children. Most literature refers to a surgical treatment for these lesions. Laryngotracheal reconstruction and cricotracheal resection are used for low- and high-grade stenosis, but decannulation is not always possible immediately after surgery. Purpose: The aim of this study was to verify the feasibility and results of endoscopic dilatations for treatment of subglottic stenosis. Method: The study encompassed a 12-year retrospective analysis of patients treated for UAS in a tertiary center. All children were symptomatic at the time of the endoscopic diagnosis. The stenosis was graded according to the Myer-Cotton criteria. Endoscopic dilatation was initiated immediately after the diagnosis. Children with grade IV stenosis underwent surgery. Results: Children with tracheal stenosis and no involvement of the subglottic area did not respond to endoscopic dilatations and underwent surgery. There were 45 children with grade I stenosis, 12 with grade II, 7 with grade III, and 4 with grade IV lesions. Patients with grade I, II, and III stenosis were a] I treated by endoscopic dilatations alone and were decannulated when asymptomatic. The average time for decannulation was 18.90 +/- 26.07 months for grade 1, 32.5 +/- 27.08 months for grade 11, and 27.57 +/- 20.60 months for grade III stenosis (P < .01, for grade II vs grade III). Conclusion: Grade I, II, and III subglottic stenoses can be safely managed by early endoscopic dilatations with a high rate of success and low rate of morbidity but require a significantly long period of treatment.

Child psychiatry takes to the streets: A developmental partnership between a university institute and children and adolescents from the streets of Sao Paulo, Brazil

Objective: High levels of domestic violence, mental illness, and alienation from authorities are associated with high incidence of children/adolescents living on the streets in low and middle income countries. The Equilibrium Project (Programa Equilibrio) was created to facilitate social reintegration through a virtual partnership between an academic psychiatric institute and highly vulnerable children and adolescents living on the streets, in group shelter with supervision, and in other high risk situations. Methods: Descriptive presentation of qualitative data and analysis of preliminary empirical data collected over a 24-month period. Results: Dialogue between academic professionals, street children, and city officials shaped The Equilibrium Project over the last 2 years. The program has progressively moved from a professional clinic setting to a community-based but protected activity center with recreational and professional services and an emphasis on linkage with social service agencies, city government and law enforcement officials in an academic research context. A total of 351 patients have been served of whom virtually all were neglected by their parents, 58.4% report physical or sexual abuse, 88.89% have been diagnosed with a psychiatric disorder, 40.4% drug use. After 2 years of operation, 63.5% (n = 223) successfully completed or continue in treatment and 34.8% (n = 122) were reunited with their families. Conclusions and Practice implications: Program development guided by consumer input led to a successful program offering professional services in a protected community setting that facilitates social reintegration by providing ""go between"" services integrating relationships between alienated consumers and formal psychiatric, pediatric, social service, and criminal justice systems.

Distinct resistance mutation and polymorphism acquisition in HIV-1 protease of subtypes B and F1 from children and adult patients under virological failure

The goal of this work was to compare the differences between human immunodeficiency Virus type 1 (HIV-1) of B and F1 Subtypes in the acquisition of major and rninot- protease inhibitor (P1)-associated resistance mutations and of other polymorphisms at the protease (PR) gene, through a cross sectional Study. PR sequences from subtypes B and F1 isolates matched according to P1 exposure time from Brazilian patients were included in this study. Sequences were separated in four groups: 24 and 90 from children and 141 and 99 from adults infected with isolates of subtypes F1 and B, respectively. For comparison, 211 subype B and 79 subtype F1 PR sequences from drug-naive individuals Were included. Demographic and clinical data were similar among B- and F1-infected patients. In untreated patients, Mutations L1OV, K20R, and M361 were more frequent in subtype F1, while L63P, A7IT, and V771 were more prevalent in Subtype B. In treated patients, K20M, D30N, G73S, 184V, and L90M, were More prevalent in subtype B, and K20T and N88S Were more prevalent in Subtype F1. A higher proportion of subtype F1 than Of subtype B Strains Containing other polymorphisms was observed. V82L mutation was Present With increased frequency in isolates from children compared to isolates from adults infected with both subtypes. We could observe a faster resistance emergence in children than in adults, during treatment with protease inhibitors. This data provided evidence that, although rates of overall drug resistance do not differ between subtypes B and F1, the former accumulates resistance at higher proportion in specific amino acid positions of protease when compared to the latter.

Myocarditis in children and detection of viruses in myocardial tissue: Implications for immunosuppressive therapy

Background: There is scarce information on the potential benefits of immunosuppression in children with myocarditis and viral genomes in myocardium. We investigated the occurrence of myocarditis in children with a preliminary diagnosis of dilated cardiomyopathy, the frequency of cardiotropic viruses in the myocardium, and the response to immunosuppression. Methods: Thirty patients (nine months to 12 years) with left ventricular ejection fraction of 22.8 +/- 4.1% were subjected to right cardiac catheterization and endomyocardial biopsy. Specimens were analyzed for the presence of inflammatory elements (Dallas criteria) and viral genome (polymerase chain reaction). Patients with active myocarditis received immunosuppressants (azatioprine and prednisone) and were recatheterized nine months later. A historical control group of nine patients with myocarditis who did not receive immunosuppressants was included. Results: Active myocarditis was diagnosed in ten patients (five with viral genomes detected). Immunosuppression resulted in a significant increase in left ventricular ejection fraction from 25.2 +/- 2.8% to 45.7 +/- 8.6% (versus 20.0 +/- 4.0% to 22.0 +/- 9.0% in historical controls, p < 0.01) and cardiac index from 3.28 +/- 0.51 L/min/m(2) to 4.40 +/- 0.49 L/min/m(2) (versus 3.50 +/- 0.40 L/min/m(2) to 3.70 +/- 0.50 L/min/m(2) in controls, p < 0.01), regardless of the presence of viral genomes (p - 0.98 and p - 0.22, respectively for the two variables). No relevant clinical events were observed. Non-inflammatory cardiomyopathy was diagnosed in 20 patients (seven with viral genomes). While on conventional therapy, there were four deaths and three assignments to transplantation, and no improvement of left ventricular ejection fraction in the remaining ones (22.5 +/- 3.6% to 27.5 +/- 10.6%). Conclusion: Children with chronic myocarditis seem to benefit from immunosuppressive therapy, regardless of the presence of viral genome in the myocardium. (C) 2009 Elsevier Ireland Ltd.

Comparison between videofluoroscopy and endoscopic evaluation of swallowing for the diagnosis of dysphagia in children

OBJECTIVE: To compare videofluoroscopy swallowing study (VFSS) with the fiberoptic endoscopic evaluation of swallowing (FEES) in children and to determine the accuracy of FEES in the diagnosis of specific swallowing disorders. STUDY DESIGN: Cross-sectional study. SETTING: Hospital da Crianca Santo Antonio, affiliated with Santa Casa de Misericordia Hospital Complex, Porto Alegre, RS, Brazil. SUBJECTS AND METHODS: FEES findings were compared to those of VFSS in 30 children. Kappa coefficients for interobserver agreement were calculated. Thereafter, these coefficients were evaluated in terms of agreement between FEES and VFSS. In addition, the sensitivity, specificity, positive predictive value, and negative predictive value of FEES were calculated for four swallowing parameters (posterior spillover, pharyngeal residues, laryngeal penetration, and laryngotracheal aspiration). RESULTS: Interobserver agreement rates greater than 70 percent were obtained for all FEES parameters analyzed, except for pharyngeal residues with puree consistency (agreement = 66.7%, K = 0.296, P = 0.091). Laryngeal aspiration and penetration yielded the best level of agreement (100%, K = 1) for the laryngeal aspiration of puree residues. CONCLUSION: The diagnostic agreement between FEES (both observers) and VFSS was low. Regarding the analyzed parameters, laryngeal penetration and aspiration yielded the highest interobserver agreement in terms of FEES, and also showed the highest specificity and positive predictive value when compared to VFSS.

Peginterferon alfa-2a plus ribavirin for chronic hepatitis C virus infection in children and adolescents

Background & Aims: This multi-center study aimed to prospectively evaluate the safety and efficacy of a genotype-based Pegylated Interferon alfa-2a/Ribavirin therapy in treatment-naive hepatitis C virus (HCV), positive HCV serology, and quantifiable HCV RNA, infected children. Methods: Eighteen children with genotypes 2 and 3 patients (group A) were assigned to medication for 24 weeks, and 47 children with genotypes 1, 4, 5 and 6 patients (group B) for 48 weeks. Results: Early response at week 12 was observed in 83% of group A patients and in 57% of group B patients (p <0.05). End of treatment response was achieved in 94% of patients in group A and in 57% in group B (p <0.001). Sustained virologic response was maintained in 89% of patients in group A and in 57% of patients in group B (p <0.01). Ten patients stopped prematurely the treatment, 2 for serious adverse event (acute hepatitis and thyrotoxicosis), and 8 because of no virologic response at week 24. Peginterferon alfa-2a and Ribavirin dose was adjusted in 15 patients (23%), 11 for neutropenia (17%), and 3 patients (5%), for anemia, respectively. Treatment-related adverse events included fever and flu-like symptoms (54%), irritability depression change of mood (34%), vomiting (23%), abdominal pain (38%), loss of appetite (21.5%) and dermatitis (29%). No influence on height growth was observed. Conclusions: Pegylated inteferon alfa-2a and Ribavirin treatment allowed to achieve SVR in 57% of pediatric patients with genotypes 1, 4, 5 and 6, and in 94% of genotypes 2 and 3. These results show an improved SVR as compared to reference series in adults with similar regimen. (c) 2010 European Association for the Study of the Liver. Published by Elsevier B.V.

Executive dysfunction in children and adolescents with temporal lobe epilepsy: Is the Wisconsin Card Sorting Test enough?

The Wisconsin Card Sorting Test (WCST) is the gold standard in the evaluation of executive dysfunction (ED) in patients with temporal lobe epilepsy (TLE). We evaluated 35 children with TLE and 25 healthy controls with the WCST and with a more comprehensive battery. Among the children with TLE, 77.14% showed impairment on the WCST. On other tests (Wechsler Intelligence Scale for Children-Digit Forward, Matching Familiar Figures Test, Trail Making Test, Word Fluency, Finger Windows, and Number-Letter Memory), impairment was demonstrated in 94.29%. The authors concluded that the WCST is a good paradigm to measure executive impairment in children with TLE: however, it may be not enough. Evaluation performed only with the WCST not only underestimated the number of patients with ED, but also missed relevant information regarding the type of ED. (C) 2009 Elsevier Inc.

Family environment patterns in families with bipolar children

Background: We studied the characteristics of family functioning in bipolar children and healthy comparison children. We hypothesized that the family environment of bipolar children would show greater levels of dysfunction as measured by the Family Environment Scale (FES). Methods: We compared the family functioning of 36 families that included a child with DSM-IV bipolar disorder versus 29 comparison families that included only healthy children. All subjects and their parents were assessed with the K-SADS-PL interview. The parents completed the FES to assess their current family functioning. Multivariate analysis of variance was used to compare the family environment of families with and without offspring with bipolar disorder. Results: Parents of bipolar children reported lower levels of family cohesion (p<0.001), expressiveness (p=0.005), active-recreational orientation (p<0.001), intellectual-cultural orientation (p=0.04) and higher levels of conflict (p<0.001) compared to parents with no bipolar children. Secondary analyses within the bipolar group revealed lower levels of organization (p=0.03 1) and cohesion (p=0.014) in families where a parent had a history of mood disorders compared to families where parents had no history of mood disorders. Length of illness in the affected child was inversely associated with family cohesion (r=-0.47, p=0.004). Limitations: Due to the case-control design of the study, we cannot comment on the development of these family problems or attribute their cause specifically to child bipolar disorder. Conclusion: Families with bipolar children show dysfunctional patterns related to interpersonal interactions and personal growth. A distressed family environment should be addressed when treating children with bipolar disorder. (C) 2007 Elsevier B.V. All rights reserved.

Western blotting method (TESAcruzi) as a supplemental test for confirming the presence of anti-Trypanosoma cruzi antibodies in finger prick blood samples from children aged 0-5 years in Brazil

Some Latin American countries have plans for total control and/or eradication of Chagas disease by the main vector (Triatoma infestans) and by blood transfusion. To achieve this, patients with Chagas disease must be identified. A Western blotting test, TESAcruzi, is described as a supplemental test for diagnosis of Chagas disease using samples collected from children <5 years living in different states of Brazil. Blood samples collected by finger prick on filter paper were sent to the test laboratory by a central laboratory to confirm results obtained previously. Ten percent of negative samples, all doubtful and all positive samples were received. Commercial reagents, IgG indirect immunofluorescence, enzyme immunoassay, and a recently introduced TESAcruzi test were used. From 8788 samples, 163 (1.85%) were reactive by IgG-ELISA and 312 (3.55%) by IgG IIF. From these, 77 (0.87%) were reactive in the TESAcruzi test. The results had high clinical value to identify those truly infected. (C) 2010 Elsevier B.V. All rights reserved.

Importance of psychological intervention for the recovery of children submitted to elective surgery

Purpose: The effects of anxiety on the patient and his/her family are known to be the main factors that influence health recovery in child surgery. When the whole family can be prepared and supported by psychologic intervention, the damage to child behavior and family anxiety is attenuated. Methods: This study was conducted in children between 2 and 6 years old, divided into 2 groups of 10 pairs each. The experimental group received psychologic intervention, whereas the control group did not. One month after the surgery, they were reevaluated and compared with the same instruments used in the beginning of the study. The instruments used were as follows: the State-Trait Anxiety Inventory with the mothers and the Rutter`s Child Behavior A2 Scale and the Posthospital Behavior Questionnaire with the children. Results: The results were compared by the Wilcoxon and Mann-Whitney nonparametric tests for independent samples, both at the P <.05 significance levels. Mothers stated that anxiety was different in the postsurgery period, showing a significant decrease when comparing the experimental and control groups. Both instruments to measure child behavior also showed that prepared children had less habit changes than the control group, which showed increased levels of inadequate behavior. Conclusions: These data confirm reports in literature regarding child preparation before medical intervention and reinforces the importance of specialized presurgery planning procedures by the proper professional interfaced with the surgical colleagues, all aiming toward the best recovery for the children.

Comparison between the reliability levels of manual palpation and pressure pain threshold in children who reported orofacial pain

The aim of this study was to compare the intra-and inter-rater reliability of pressure pain threshold (PPT) and manual palpation (MP) of orofacial structures in symptomatic and symptom-free children for temporomandibular disorders (TMD). Fourteen children reporting pain in masticatory muscles or the temporomandibular joint and 16 symptom-free children were randomly assessed on three different occasions: by rater-1 in the first and third session and by rater-2 in the second session. The trained raters applied algometry and MP as recommended by the Research Diagnostic Criteria for TMD. Intraclass correlation coefficients and the Kappa statistic were used to assess the levels of reliability of PPT and MP, respectively. Excellent intra-and inter-rater reliability levels were observed for PPT values at most of the examined sites for symptom-free children and excellent and moderate reliability levels for children reporting pain. For MP, moderate and poor intra-rater and inter-rater reliability levels were observed for most sites in both groups. Algometry showed higher reliability levels for both groups of children and is recommended for pain assessment in children in association with MP. (C) 2010 Elsevier Ltd. All rights reserved.

Cephalometric evaluation of facial pattern and hyoid bone position in children with obstructive sleep apnea syndrome

Objectives: To assess the development of face and hyoid bone in children with obstructive sleep apnea syndrome (OSAS) through lateral cephalometries. Materials and methods: Children aged 7-10 years with mixed dentition and with no previous otorhinolaryngologic, orthodontic or speech therapy treatments were studied. Twenty nasal breathers were compared to 20 mouth breathing children diagnosed as OSAS patients. All children underwent otorhinolaryngologic evaluation and cephalometries; children with OSAS also underwent nocturnal polysomnography in a sleep laboratory. Results: Children with OSAS presented increase in total and lower anterior heights of the face when compared to nasal breathers. In addition, children with OSAS presented a significantly more anterior and inferior position of the hyoid bone than nasal breathers. No significant differences in upper, anterior or posterior heights of the face were observed between groups. Conclusion: The results suggest that there are evident and early changes in facial growth and development among children with OSAS, characterized by increased total and inferior anterior heights of the face, as well as more anterior and inferior position of the hyoid bone.

Conductive hearing loss in children with bronchopulmonary dysplasia: A longitudinal follow-up study in children aged between 6 and 24 months

Aims: To determine the occurrence of isolated and recurrent episodes of conductive hearing loss (CHL) during the first two years of life in very low birth weight (VLBW) infants with and without bronchopulmonary dysplasia (BPD). Study design, subjects and outcome measures: In a longitudinal clinical study. 187 children were evaluated at 6, 9, 12,15 18 and 24 months of age by visual reinforcement audiometry, tympanometry and auditory brain response system. Results: Of the children with BPD, 54.5% presented with episodes of CHL, as opposed to 34.7% of the children without BPD. This difference was found to be statistically significant. The recurrent or persistent episodes were more frequent among children with BPD (25.7%) than among those without BPD (8.3%). The independent variables that contributed to this finding were small for gestational age and a 5 min Apgar score. Conclusions: Recurrent CHL episodes are more frequent among VLBW infants with BPD than among VLBW infants without BPD. (C) 2010 Elsevier Ireland Ltd. All rights reserved.
