Autism's Impact on Cochlear Implantation Surgery Outcomes in Deaf Children.

Introduction: Cochlear implants (CI) provide a hearing sense for severe to profound hearing-impaired patients, both adults and children, and they are a broadly effective and accepted therapeutic method for those patients. Also, Deaf children with comorbidities, including autism spectrum disorders (ASDs), undergo cochlear implantation. ASDs are a group of developing disorders characterized by abnormalities in social interaction and communication with limited repetitive patterns of behavior. This study aimed to assess the effect of Autism on CI surgery outcomes in Deaf Children. Materials and Methods: We followed 12 autistic patients with cochlear implantation and 12 non-autistic cochlear-implanted patients for two years. The Categories of Auditory Performance (CAP) and Speech Intelligibility Rating (SIR) scores were used to assess 6, 12, and 24 months after cochlear implantation surgery. Results: During the 24-month follow-up, the CAP means scores increased in both groups, and SIR and CAP progresses were considerably greater in non-ASD children (P<0.001). However, in ASD children, the progress of CAP and SIR variables were significant, with 99% and 95% confidence, respectively, at 24 months after surgery. Conclusion: Although the CIs could improve hearing performance in autistic patients, speech development after CIs in autistic children could affected by several factors, including the severity of autism, and this can be effective in providing pre-implant counseling to parents. The application of the alternative communication methods could be taken into account as a potential rehab technique.

Treatment of Allergic Patients with Adenotonsillar Hypertrophy: Surgery Versus Medication Therapy:.

BACKGROUND: Adenotonsillar hypertrophy (AH) is the most common cause of respiratory obstruction of the upper airway, and tonsillectomy is one of the most frequently performed surgical interventions in children. It has been proposed that medical treatment in an allergic state could decrease the size of AH. Therefore, this study aimed to compare the outcomes of surgery and medical therapies among allergic children with AH. MATERIALS AND METHODS: This case-control study was carried out on 68 children with AH in an allergic state who were referred to the Pediatrics Hospital of Tabriz Medical University. They were divided into two groups and matched according to sex, age, and primary clinical signs and symptoms. Patients received surgery (case group) and medication (control groups) for treated AH. Finally, they were compared according to the results of treatment and recurrence rate. RESULTS: The mean age of children in the case and control groups was 6.3±2.3 and 6.8±2.1 years, respectively. There was no significant difference in improving clinical signs and symptoms between the two groups. In the case group, no improvement of clinical signs and symptoms was observed in one patient compared with two patients in the control group. In the control group, no decrease in the size of the tonsils was observed in three patients. Recurrence of clinical signs of AH was observed in six (17.6%) patients of the control group, and there was a significant difference between the two groups (P0.001). CONCLUSION: Our findings showed no significant differences in the outcomes of the two therapeutic methods for AH in an allergic state. However, medical treatment needs a long time to affect, but surgery can act quickly. Recurrence of AH after medical therapy could occur.

Comparison of the Pediatric Cochlear Implantation Using Round Window and Cochleostomy.

INTRODUCTION: Cochlear implantation (CI) is now regarded as a standard treatment for children with severe to profound sensor neural hearing loss. This study aimed to compare the efficacy of the round window approach (RWA) and standard cochleostomy approach (SCA) in the preservation of residual hearing after CI in pediatric patients. MATERIALS AND METHODS: This double-blind randomized controlled trial was conducted on 97 pediatric patients receiving CI with 12-month follow-up. The study population was divided into two groups according to the surgical approaches they received, including RWA and SCA. Consequently, the patients were evaluated based on the Categories of Auditory Performance scale (CAP) and Speech Intelligibility Rating (SIR) test 45-60 days and 3, 6, 9, and 12 months post-surgery. RESULTS: The CAP and SIR mean scores increased in both groups during the 12-month follow-up. This upward trend was significant in both groups (P<0.001). There was no significant difference between the two treatment groups in any of the follow-up stages regarding the CAP mean score. The mean SIR score (P=1.14±0.40) was significantly higher in the RWA group 3(P=0.001), 6(P=0.008), and 9(P=0.006) months after the surgery. However, there was no significant difference between the RWA and SCA groups, regarding 1-year SIR (P=0.258). CONCLUSION: The CI with either RWA or SCA could improve hearing and speech performance in pediatric patients. Although mid-term speech intelligibility was better for RWA, there was no significant difference in the 1-year outcome between these two methods.

Effect of Probiotics on Allergic Rhinitis: A Randomized, Controlled, Clinical Trial.

BACKGROUND: Allergic rhinitis (AR) is one of the most common diseases in the world and affects about 10-50% of the general population. Probiotics are live microorganisms that help the normal state of the intestine, and if prescribed correctly, they can stimulate the mucosal immune system to prevent inflammatory symptoms of allergy and atopy. The present study aims to investigate the role of probiotics in the treatment of AR when added to standard therapy as adjuvant agents. MATERIALS AND METHODS: In this clinical trial study, 28 patients older than 15 years with AR randomly divided into probiotics and control groups. The probiotics group received standard therapy for AR accompanied by probiotic capsules every 12 hours for eight weeks, whereas the control group received standard therapy for AR with placebo capsules as the same protocol. Data were analyzed using SPSS Version 23 (IBM Corporation, Armonk, NY, USA) and, the P-value less than 0.05 was considered statistically significant. RESULTS: In the probiotics group, 14.3% of patients had sneezing at the baseline, which significantly decreased to 4.6% (P<0.01). Also, the necessity for nasal and oral corticosteroids after treatment with probiotics in the probiotics group was less than the control group (P<0.01). Although cough, nasal discharge, conchae hypertrophy, and night sleep disorders reduced after treatment with probiotics, this reduction was not statistically significant between the two groups. CONCLUSION: Based on the results of this clinical trial, the use of probiotics had no significant effect on the outcome of patients with AR.

Comparison of Auditory Brain Stem Responses and Otoacoustic Emission of Autism with Healthy Children.

BACKGROUND: Autism is a neurodevelopment disorder, including difficulty in establishing relationships and social interaction, difficulty in communication, performing restricted, and repetitive behaviors. The impaired reception and integration of sensory information especially auditory data are one of the main characteristics of children with autism. According to various studies, the brain stem plays a key role in the reception and integration of auditory and sensory data. Hence, this study aims to comparison auditory brain stem responses (ABR) and otoacoustic emission (OAE) of autism patients with healthy children. MATERIALS AND METHODS: This case-control study was performed on 20 autism children (4-8 years old) as case group who referred to psychiatry clinics affiliated with Tabriz University of Medical Sciences and 20 healthy age-matched as the control group. The severity of autism was evaluated by the Gilliam Autism Rating Scale (GARS). Also, ABR and OAE were recorded, and all data compared with the healthy children. RESULTS: The latencies between the waves III-V and I-V bilaterally, and wave V bilaterally and wave I in the left ear showed a significant increase in children with autism compared to the healthy group. CONCLUSION: This study shows that there was a reduced nerve conduction velocity in the auditory pathway of the brain stem in children with autism compared to healthy children.

Evaluation of Children Quality of Life after Serous Otitis Media Surgery.

Introduction: Otitis media with effusion is a common childhood disease diagnosed with the accumulation of serous fluid or mucous in the middle ear. If not treated, the sustainable effusion leads to change and destruction of middle ear structures. One of the most successful treatment methods is myringotomy and ventilation tube insertion, which leads to improvement of patients' quality of life. The aim of this study was to evaluate children's quality of life after inserting ventilation tubes. Methods: This prospective cross-sectional study examined the quality of life of the children suffering from otitis media with sustainable effusion, who were candidates for ventilation tube insertion. Otitis Media outcome-22 (OMO -22) questionnaire, was used to record the patients' problems in a 12-week period before and after surgery. Results: In this study, 70 patients, including 43 (61.4%) boys and 27 (38.6%) girls (1y-13y), who completed the questionnaire, were studied. Treatment with ventilation tubes improved many physical symptoms of the hearing loss along with speech and behavioral symptoms. A significant reduction was observed in the number of physician visits and the use of antibiotics for ear problems. Conclusion: Ventilation tube insertion not only reduced the symptoms of otitis media with effusion, but also improved the children's quality of life.

Is fasting duration important in post adenotonsillectomy feeding time?

BACKGROUND: Adenotonsillectomy is a common otolaryngology surgery. Nausea and vomiting are the most common complications of this procedure with a prevalence ranging from 49% to 73 %. OBJECTIVES: Our aim was to evaluate the effects of short time fasting protocol on decreasing postoperative pain, nausea and vomiting, and initiation of oral feeding after adenotonsillectomy. PATIENTS AND METHODS: 120 children aged 4 to 14 years candidates for adenotonsillectomy were randomly divided into intervention and control groups (n = 120, 60 in each group). Each patient of the intervention group was given oral dextrose 10% as much volume as he could consume at 3 and 6 hours prior to the operation. All the data including pain severity, nausea and vomiting of the patients, the time of oral feeding initiation etc. were gathered in checklists after the operation. Statistical analyses were then performed using Statistical Package for the Social Sciences (SPSS) software version 16. Descriptive statistical methods and mean difference test for independent groups and chi square test or Fisher exact test, and if regression needed model test were applied. A P value of 0.05 or less was considered statistically significant. RESULTS: The amount of Acetaminophen administered for the intervention group was significantly lower than the control group, and also the time of oral feeding initiation was significantly shorter in the intervention group than the control group (P < 0.005). Pain severity at all occasions following surgery was significantly lower in the intervention group than the control group (P < 0.001). Although frequency of nausea at recovery time was significantly lower in the intervention group than the control group (P < 0.002), there were no significant differences in frequency of nausea between the two groups at other postoperative occasions. Postoperative vomiting frequency was not significant between the two groups at any occasions. CONCLUSIONS: The findings of this survey showed that shortening the duration of pre-adenotonsillectomy fasting period and hydration of patients several hours prior to the operation might be effective in decreasing postoperative pain and facilitating postoperative oral feeding initiation. Nevertheless this method does not seem to prevent postoperative nausea and vomiting.

Does adenotonsillectomy alter IGF-1 and ghrelin serum levels in children with adenotonsillar hypertrophy and failure to thrive? A prospective study.

OBJECTIVES: Adenotonsillar hypertrophy (ATH) contributes to upper airway obstruction and recurrent tonsillitis in children. The aim of this study was to evaluate the effect of adenotonsillectomy on serum IGF-1 and ghrelin levels in children with ATH failure to thrive. METHODS: Forty pre-pubertal children with more than 5 years of age (6.57 ± 1.284 years) suffering from ATH, sleep disorder breathing, snoring, open mouth breathing and growth retardation were studied. Blood samples were taken eight hours after fasting and weight and height were measured by SECA instrument. Blood samples were centrifuged immediately and the extracted sera were stored at -70 °C in Eppendorf vials. IGF-1 and ghrelin were measured by ELISA kit. Patients with adenotonsillectomy indication underwent adenotonsillectomy and serum levels of IGF-1 and ghrelin were measured 12 months after operation. RESULTS: Weight, height and BMI were increased significantly after operation (P < 0.001). Serum IGF-1 and ghrelin levels increased significantly after operation compared to before operation (P < 0.001). CONCLUSION: Growth retardation in children with adenotonsillar hypertrophy is related to lower serum IGF-1 levels. Ghrelin levels increase before the meals and ghrelin increases hunger and food intake. The results obtained from our study confirmed that weight, height and BMI increase significantly following adenotonsillectomy; this could in turns prevent undesirable and irreversible physiological changes that occur due to adenotonsillar hypertrophy. Adenotonsillectomy in children with adenotonsillar hypertrophy and failure to thrive increases IGF-1 and Ghrelin serum levels which might contribute to the improvement in the growth pattern of the children.

Tissue fatty acid composition in obstructive sleep apnea and recurrent tonsillitis.

OBJECTIVE: Tonsillar hypertrophy cells appear to have an altered lipid metabolism as evidenced by modulated inflammatory cytokines that affect tissue lipid metabolism. The aim of this study was to investigate differences in tissue fat composition between obstructive sleep apnea (OSA) and recurrent infective tonsillitis (RT) in children. METHODS: Tonsillar tissues were collected from 114 patients with OSA and 92 patients with RT, aged 4-10 years, during tonsillectomy. The tissue lipid extracts were analyzed by gas liquid chromatography for a comprehensive fatty acid profile. RESULTS: In the tonsillitis tissue, the levels of palmitoleic acid (16:1n-7; P=0.002) and oleic acid (18:1n-9; P=0.003) were higher, and the level of stearic acid (18:0; P=0.004) was lower than that in the hyperplastic tonsillar tissue. Overall, tonsillar tissue of patients with RT had a significant increase in the total monounsaturated fatty acids (+9.9%; P<0.001) and the fatty acid desaturation index (+20.5%; P<0.001). Furthermore, oleic acid content of tonsillar tissue was positively correlated with BMI (r=0.20, P=0.004), snoring (r=0.16, P=0.022) and hypertrophy grade (r=0.18, P=0.023), which remain significant in the subgroup analysis by hypertrophy type. CONCLUSIONS: The change in the fatty acid composition may be regarded as an indicator of altered lipid metabolism occurring in vivo during human tonsillar hypertrophy, which might be linked to the severity or type of the tissue damage.

Circulating phospholipase-A2 activity in obstructive sleep apnea and recurrent tonsillitis.

OBJECTIVE: Phospholipase A2 (PLA2) plays a major part in growth regulation, differentiation and inflammation. It has been proposed as an evaluating marker for infection and inflammation. The aim of this study was to investigate activity of serum type II secretory PLA2 (sPLA2 IIa) in obstructive sleep apnea (OSA) and recurrent infective tonsillitis (RT) in children. METHODS: Activity of serum sPLA2 IIa was determined in children who underwent tonsillectomy, including OSA in 126 cases and RT in 60. Serum enzyme activities were measured using the standard assay with Diheptanoyl Thio-Phosphatidylcholin as substrate. RESULTS: The sPLA2 IIa activity of serum was significantly higher in RT than in OSA (P<0.01). Serum sPLA2 IIa activity in the RT patients was positively correlated with BMI (r=0.26; P=0.02), which was not apparent in OSA (r=0.14; P=0.09). CONCLUSION: This study suggests that serum sPLA2 IIa activity may be considered as a supportive diagnostic marker in suspected or clinically unclear cases of RT children.

Auditory brain stem response and otoacoustic emission results in children with end-stage renal disease.

BACKGROUND: Abnormalities in auditory system are frequent in patients with end stage renal disease (ESRD). There is not yet any consensus for the effect of renal failure and hemodialysis on auditory complications. The aim of this study was to evaluate the auditory abnormalities in pediatric ESRD patients undergoing long term hemodialysis and compare the results with those of nondialytic chronic renal failure (CRF) children and controls. METHODS: Children aged 1-16 years were evaluated in three groups: 25 ESRD patients undergoing hemodialysis, 25 nondialytic patients with CRF, and 25 age and sex-matched normal counterparts. Patients with history of otological diseases, ear trauma, diabetes mellitus, receiving ototoxic drugs and syndromes with hearing abnormalities were excluded. The auditory brainstem response (ABR) and otoacoustic emission (OAE) were tested in all subjects. Frequency of cases with abnormal findings was compared between the groups. RESULTS: The ABR testing was abnormal in 11 (44%) dialytic patients with normal results in all nondialytic CRF cases and controls (p<0.001). The OAE testing was abnormal in all dialytic patients with abnormal ABR testing results (44%), in 1 (4%) nondialytic CRF patient and in no controls (p<0.001). There ware no significant differences with regard to age, gender, height, weight, blood pressure, serum levels of blood urea nitrogen (BUN), creatinine, sodium, and potassium, glomerular filtration rate (GFR), duration of dialysis and dialysis adequacy between dialytic patients with and without abnormal results of ABR/OAE testing. CONCLUSION: Sensorineural hearing loss is rare among nondialytic pediatric patients with CRF but very common in ESRD children undergoing long term dialysis.

Do pre-adenotonsillectomy echocardiographic findings change postoperatively in children with severe adenotonsillar hypertrophy.

PURPOSE: Hypertrophy of adenotonsillar tissue is one of the most common problems in childhood age and causes upper airway obstruction and even obstructive sleep apnea symptoms in severe forms. The aim of this study is to evaluate the changes of pre-adentonsillectomy echocardiographic findings after operation. MATERIAL AND METHODS: From August 2007 to November 2008, 55 children with adenotonsillar hypertrophy and obstructive-sleep symptoms (aged 3-11 years old of which 35 were males and 20 females) were randomly selected. Preoperatively echocardiography was performed for all patients by the pediatric cardiologist. In control group 55 children who referred to otolaryngology clinic because of non adenotonsillar related disease evaluated. One month and six months after operation, patients with positive findings were followed up and again echocardiography was performed separately. RESULTS: No complaints of apnea were reported. Tonsillar grades of all cases were type III or IV. The preoperative mean pulmonary arterial pressure levels of the 4 (7.3%) children were higher than normal range (25 mm Hg) and it decreased significantly after operation (P < 0.000) (Preoperative MPAP = 32 ± 3 mm Hg, and six months postoperative follow up, MPAP = 11 ± 5 mm Hg). All the patients' parents complained about severe open mouth snoring, agitated sleep and hyperpnoea of their children. The preoperative tricuspid regurgitation pressure level of 7 children was higher than normal range and it decreased significantly after operation (P < 0.000 preoperative TR = 34 ± 8 mm Hg postoperative TR = 19 ± 6 mm Hg). AC/ET in these seven patients were lower than 0.4. In control group echocardiography findings are normal. CONCLUSION: Severe chronic hypertrophic adenotonsillar tissue caused higher tricuspid regurgitation pressure and mean pulmonary arterial pressure.

Acoustic emissions from the inner ear and brain stem responses in type 2 diabetics.

BACKGROUND: The purpose of this study was to evaluate the auditory brain stem response (ABR) and acoustic emissions of the inner ear (OAE) in middle-aged type 2 diabetics. METHODS: Fifty type 2 diabetic and nondiabetic patients aged 40-50 years and attending the Tabriz Medical University outpatient clinics were recruited for this study during 2009-2010. All ABR and OAE procedures were implemented by an audiometrist. The relationship between ABR and OAE findings and demographic, laboratory, and clinical characteristics was investigated. RESULTS: Fifty patients (34 female and 16 male) of average age 45.7 ± 3.0 years were entered into the study. In the type 2 diabetic group, disordered ABR was found in at least one ear in 8% of cases and disordered OAE was recorded in at least one ear in 16% of cases, with no significant difference between the diabetic and nondiabetic groups. Mean age, duration of diabetes, serum HbA(1c) levels, and prevalence of female gender were higher in the diabetic group. CONCLUSION: According to our findings, the prevalence of ABR and OAE is not significantly different between type 2 diabetics and nondiabetics.

Comparative assessment of Helicobacter pylori colonization in children tonsillar tissues.

OBJECTIVE: The objective was to survey the results of RUT (rapid urease test) in children tonsillar tissues. METHODS: In a prospective clinical study 285 children (4-14 years) tonsillar tissue tested with RUT (rapid urease test) and histopathologic biopsy and simultaneously serum IgG Helicobacter pylori level was measured for all patients. RESULTS: One hundred and thirteen patients (39.6%) were positive to H. pylori in histopathologic examination. Forty patients (14%) had positive RUT and 15 patients had positive serum IgG anti-H. pylori level. In 40 patients the results in both histopathology and RUT were positive (P=0.000) although in 172 patients the results in both histopatologhic and RUT were negative (P=0.000). CONCLUSIONS: This study showed that H. pylori was present in tonsillar tissue and RUT is not sensitive enough for diagnosis of H. pylori in tonsillar tissue. Indicating that H. pylori has a possible role in reservoir of H. pylori in children.

A neonate with cleft palate and a fetal mass in the oral cavity: a rare case of an oral fetus-in-fetu.

Fetus-in-fetu is a rare congenital condition in which a malformed fetus-like structure is found in the body of its twin. We report a unique case of a male neonate with cleft palate and a fetus-like structure arising in his oral cavity. The neonate underwent emergent surgical removal of the mass immediately after delivery. Radiological and pathological studies of the resected mass provided supportive evidence for the case of an oral fetus-in-fetu. To our knowledge, there are few cases of oral fetus-in-fetu in the literature. Moreover, the presence of cleft palate in this neonate is of potential interest and clinical importance.
