Ambulatory blood pressure monitoring in children with obstructive sleep apnea and primary snoring

Objective: To evaluate the systemic blood pressure (BP) during daytime and nighttime in children with sleep breathing disorders (SBD) and compare parameters of BP in children with diagnosis of obstructive sleep apnea syndrome (OSA) to those one with primary snoring (PS).Methods: Children, both genders, aged from 8 to 12 years, with symptoms of SBD realized an overnight polysomnography followed by a 24 h recording of ambulatory BP.Results: All subjects presented with a history of snoring 7 nights per week. Children who have apnea/hipoapnea index >= four or a apnea index >= one presented a mean BP of 93 +/- 7 mmHg and 85 +/- 9 mmHg diurnal and nocturnal respectively whereas children who have a apnea/hipoapnea < four or a apnea index < one presented 90 +/- 7 mmHg and 77 +/- 2 mmHg. Eight children out of fourteen, from OSA group, lost the physiologic nocturnal dipping of the blood pressure. Among OSA children 57% were considered non-dippers. Two (16%) have presented absence of nocturnal dipping among children with primary snoring. The possibility of OSA children loosing physiologic blood pressure dipping was 6.66 higher than the possibilities of patients from PS group.Discussion: Our results indicate that children with sleep apnea syndrome exhibit a higher 24 h blood pressure when compared with those of primary snoring in form of decreased degree of nocturnal dipping and increased levels of diastolic and mean blood pressure, according to previous studies in literature. OSA in children seems to be associated to the development of hypertension or other cardiovascular disease. (C) 2012 Elsevier B.V. All rights reserved.

Lesões sequelares na laringe em pacientes com paracoccidiodomicose

A Paracoccidioidomicose (PCM) é uma doença sistêmica que em sua forma sequelar se caracteriza por manifestações clínicas relacionadas às alterações anatômicas ou funcionais de órgãos e sistemas comprometidos no período de estado. OBJETIVO: Descrever as alterações anatômicas e funcionais laríngeas sequelares em pacientes com paracoccidioidomicose. MATERIAL E MÉTODOS: Estudo retrospectivo, sendo avaliados 49 pacientes do sexo masculino, na faixa etária de 30 a 60 anos, entre 1999 a 2004, com diagnóstico de PCM em acompanhamento pela disciplina de Moléstias Infecciosas e Parasitárias, confirmado pela demonstração do fungo em escarro, exame citológico ou histopatológico. RESULTADOS: As pregas vocais foram a estrutura laríngea mais afetada, em 67% dos pacientes verificaram-se alterações. A epiglote estava acometida em 55% dos casos. As pregas ariepiglóticas tinham modificações em 53% dos pacientes. As pregas vestibulares estavam alteradas em 46% dos casos. em 40% dos casos verificaram-se alterações em aritenoides. Na fonação, 28% tinham limitação ao movimento das cordas vocais, paresia unilateral ocorreu em 4% casos. em 24% havia restrição da luz supraglótica e 4% tinham estenose glótica, sendo que 2% precisaram de traqueotomia. CONCLUSÃO: As lesões sequelares na laringe devido à infecção pelo P. brasilienses são extensas e causam restrições funcionais na maioria dos casos.

Evaluation of obstructive sleep apnea in obese patients scheduled for bariactric surgery

PURPOSE: To evaluate the frequency of obstructive sleep apnea (OSA) in obese patients scheduled for bariatric surgery and their identification for risk of OSA by Berlin Questionnaire (BQ) and excessive daytime sleepiness by Epworth Sleepiness Scale (ESS). METHODS: Fifty nine patients were evaluated by BQ and ESS. Out of these individuals, 35 performed a full-night sleep study using a type 3 portable monitoring (PM). The questionnaire results were compared for gender and BMI. The presence and severity of OSA was correlated with gender and both questionnaires. RESULTS: 94.75% of the respondents presented high risk for OSA by BQ and 59.65% presented positivity by ESS. Taking into account the AHI> 5 per hour for OSA diagnosis, all of them presented OSA, average AHI of 45.31±26.3 per hour and 68.6% have severe OSA (AHI>30). The male patients had a higher AHI (p<0.05). There was a positive correlation between the positivity in both questionnaires as well as the severity of OSA measured by AHI (p<0.05). CONCLUSION: The frequency and severe obstructive sleep apnea in the studied group is high. The Berlin Questionnaire and Epworth Sleepiness Scale had a positive correlation with the diagnosis of OSA in the group studied.

Sleep apnea and automobile accidents: Review of regulation for drivers

Several studies show a crescent association between sleep-disordered breathing, excessive sleepiness and automobile accidents. Many countries already discussed about specific regulations for drivers with these conditions, including questionnaire and/or investigation by a qualified specialist. In Brazil, these discussions have barely begun. In view of that, we suggest some items to be included in our traffic law.

Argon laser for treatment of benign eyelid tumors

Small lesions located in the skin might be treated using the laser system. The purpose of this is to report the therapy of benign eyelid tumors using argon laser. Forty-four benign eyelid tumors were treated using argon blue-green laser with spot size of 500 μm, power from 1000 to 1200 mW and 0.3 second exposure time. The eyelid tumors were located mainly in the upper eyelid (65.9%) and the skin tag was the most frequent treated lesion (43.2%). The average number of laser shots to treat the lesions was 165. There was not observed any complication and all patients were satisfied with the results. The authors are considering the argon laser a benefit therapeutic method to treat benign tumors located in the eyelids.

Pediatras e os distúrbios respiratórios do sono na criança

OBJECTIVES. assessment of opinions and practices of pediatricians concerning sleep-disordered breathing (SDB) in children. Methods. randomly 516 pediatricians were selected in the state of São Paulo, Brazil. A survey mailed to them included questions regarding: their professional profile, knowledge about SDB in childhood, opinions and practices for diagnosis and treatment of these diseases. RESULTS. 112 anonymous completed surveys were returned (21.7%). The teaching of SDB during medical school and pediatric residency training was considered unsatisfactory respectively by 65.2% and 34.8% of the pediatricians. Forty-nine respondents (43.8%) rated their knowledge about SDB in children as regular, 39 (34.8%) as good and 17 (15.2%) as unsatisfactory. The most important sleep-related questions were: mouth breathing, breathing pauses, sleep amount, excessive daytime sleepiness and nocturnal wheezing. Clinical aspects regarded as the most significant for suspecting obstructive sleep apnea syndrome (OSAS) were: breathing pauses, adenoid hypertrophy, mouth breathing, craniofacial anomaly and snoring. The most frequent practices for evaluation of OSAS in children were: cavum radiography with referral to an otorhinolarnygologist (25%) and nocturnal pulse oximetry (14.2%). Only 11.6% of pediatricians recommended overnight polysomnography and 4.5%, nap polysomnography. The most effective practices for SDB were considered to be: adenoidectomy and adenotonsillectomy, parents counseling, weight loss and sleep hygiene. CONCLUSIONS. there is a gap between research on SDB in childhood and pediatric practice. © 2006 Associação Médica Brasileira.

Distúrbio de hiperatividade e déficit de atenção na síndrome de apnéia obstrutuiva do sono: Há melhora com tratamento cirúrgico?

Neuropsychological disorders are frequently associated with obstructive ventilatory disorders (OVD). Aim: To analyze the incidence of neuropsychological disorders in Brazilian children with OVD, using a screening questionnaire and to compare the answers given before and after surgery. Patients and Methods: We studied 30 children with clinical diagnosis of OVD. The children were divided into 3 groups: group I, children aged 4 to 7; group II, from 8 to 10; and group III, children over 11. The applied questionnaires were answered by the parents or tutors, and comprised 30 questions, 10 for each disorder: attention deficit, hyperactivity and impulsivity. The children were diagnosed with one of the disorders when presented 3 or more positive answers. The follow up interview occurred 6 months after adenotonsillectomy. Results: There was a predominance of male gender (60.6%) over female gender (39.4%). Group II presented the highest number of significant changes, with reductions raging from 87.5% to 33.3% of patients with attention deficit, 75% to 50% of the hyperactive patients, and 50% to 33% of the impulsive patients. Conclusion: There was neuropsychological improvement after the surgery, which occurred mainly in the children from group II. More interaction among health professionals is necessary when diagnosing and following up similar cases.

Incidência e evolução da polipose nasal em crianças e adolescentes com fibrose cística

Nasal polyps are a clinical sign of alert for investigating Cystic Fibrosis (CF). Aims: To study the incidence of nasal polyps in children and adolescents with cystic fibrosis, its possible association with age, gender, clinical manifestations, genotype and sweat chlorine level, and its evolution with topical steroid therapy. Methods: Clinical symptoms, sweat chlorine level and genotype were studied in 23 cystic fibrosis patients. Nasal polyps were diagnosed by nasal endoscopy and treated with topical steroids during 6 months, followed by a second nasal endoscopy. Fisher test was used for statistical analysis. Results: Nasal polyps were found in 39.1% of the patients (five bilateral, four unilateral), all older than six years, recurrent pneumonia in 82.6%, pancreatic insufficiency in 87% and malnutrition in 74%. No association was seen between nasal polyps and sweat chlorine level, genotype, clinical sings of severity and nasal symptoms. Seven patients improved in their nasal polyps with topical steroids, six showed complete resolution. Conclusion: The study showed a high incidence of nasal polyps in older children, who span the entire range of clinical severity, even in the absence of clinical nasal symptoms. Topical steroid therapy showed good results. An interaction among pediatricians and otolaryngologists is necessary for diagnosis and follow-up. 2008 © Revista Brasileira de Otorrinolaringologia.

Oral stomatitis induced by endogenous progesterone: Case report

Oral stomatitis induced by endogenous progesterone is a rare clinical condition which may be associated with cutaneous involvement. That is probably due to the peak of progesterone production during the luteal phase of the menstrual cycle. In the present case report, a 21-year-old patient displayed recurrent ulcerative lesions located on the buccal mucosa or the upper lip, on a monthly basis since the age of 15. Such lesions would always manifest themselves on the second day until the end of the menstrual cycle. © 2009 Informa UK Ltd All rights reserved.

Edema agudo de pulmão de pressão negativa como complicação grave de síndrome de apneia obstrutiva do sono em crianças. Relatos de casos

Introduction: Obstructive sleep apnea syndrome is related to cardiopulmonary complications in children. It is important to know its patophysiology and possible complications to help reduce risks in this group. Aims: To report three cases of severe cardiorespiratory complications of obstructive sleep apnea managed in the intensive care unit (ICU). Case report: Two children with no previous diagnosis of obstructive sleep apnea syndrome suffered acute congestive heart failure and acute lung oedema with need of ICU and improved after adenotonsillectomy. In a third case, the patient had acute lung oedema as a complication after adenotonsillectomy. Conclusions: Paediatricians and otolaryngologists must be aware of the clinical manifestations of severe sleep apnea. Early referring to treatment and special attention at pre and post surgical periods are essentials to avoid serious complications.
