Abstract: Introduction: The nasolabial cyst is a rare disease, usually unilateral, benign, of embryonic origin, located in soft parts from the nasolabial folds and nasal wings. The diagnosis is essentially clinic, take into consideration the cyst topography, that is usually asymptomatic. Objective: This article has as main goal the description of a unusual case of nasolabial bilateral cyst with nasal obstruction, its treatment, anatomic pathological and accompaniment, besides the literature review. Case Report: Female patient, brown, 24 years old, showing bulging in nasolabial region and nasal obstruction. Physical and complementary exams with nasolabial cyst. Indicate surgical treatment of excision of the lesion. Final Considerations: The nasolabial bilateral cyst, although is rare, is a possible cause for the nasal obstruction, with good response to surgical therapy.

Abstract: it is well known that mouth breathing is associated with adenotonsillar hypertrophy - which is the main cause of obstructive sleep apnea among children. despite the importance of this matter, there are only a handful of studies showing the relationship between osas and mouth breathing. aim: to determine the prevalence of obstructive sleep disorders in mouth breathing children and study its correlation with otorhinolaryngological findings. study design: retrospective cohort study. method: data analysis from 248 medical charts of mouth breathing children seen at the pediatric otolaryngologic division of a large medical institution between the years of 2000 and 2006. all patients had nasofibroscopy and or cavum radiographs and polysomnographic exams. according to the apnea index, patients were classified as primary snorers (ai<1); and as osas (>1). results: from 248 patients included in the study, 144 (58%) were primary snorers and 104 (42%) had osas. the most prevalent otorhinolaryngological findings were adenotonsillar hypertrophy (n=152; 61.2%), tonsilar hypertrophy (n=17; 6.8%), adenoid hypertrophy (n=37; 14.9%), rhinitis (n=155; 62.5%) and secretory otitis (n=36; 14.5%). conclusions: primary snoring and osas are frequent findings in mouth breathing children. the most frequent otorhinolaryngological disorder in children with osas is adenotonsillar hypertrophy with or without rhinitis.

Abstract: introduction: the obstructive sleep apnea syndrome (osas) is a respiratory disorder that occurs during sleep and it is relatively common in children. aim: the goal of this paper is to verify if there is a relationship between the obstructive sleep apnea syndrome (osas) and auditory processing. method: in order to do that, three groups of children ranging in age from 5 to 11 were studied, including a normal group. twenty subjects who made up the study group were submitted to ear, nose and throat (ent) exams and to polysomnography (psg), and were divided in two groups: group i (ro) comprised of 10 children who presented oral breathing and displayed normal psg, and group ii (sas) comprised of 10 children who presented oral breathing and displayed abnormal psg. their performance was compared to the performance of the third group - group iii (ren) comprised of 10 children who did not refer ent difficulties. all the subjects completed a basic audiometric assessment as well as an auditory processing diagnosis. results: the analyses of the results revealed a statistically significant difference in ent exams related to the turbinate and the palatine tonsils. group ii presented a higher incidence of turbinate hypertrophy levels ii and iii (p < 0.001) and palatine tonsils hypertrophy grades iii and iv (p 0.007). regarding the auditory processing assessment, a statistically significant difference (p < 0.001) was obtained in the dichotic digits test. group ii performed worse than group iii. also, for the non-verbal sequence memory test, group ii obtained a worse result (p < 0.022) than group i. conclusions: subjects with osas obtained worse results in auditory processing tests.
The modelling of a textile dyeing process utilizing the method of volume averaging
Souza, A.A.Ulson de;Whitaker, S.;
Brazilian Journal of Chemical Engineering , 2003, DOI: 10.1590/S0104-66322003000400011
Abstract: in this work the modelling of a process of textile dyeing of a single cotton thread is presented. this thread moves at a constant velocity within a homogeneous dye solution under steady state conditions. the method of volume averaging is applied to obtain the mass transfer equations related to the diffusion and adsorption process inside the cotton thread on a small scale. the one-equation model is developed for the fiber and dye solution system, assuming the principle of local mass equilibrium to be valid. on a large scale, the governing equations for the cotton thread, including the expression for effective diffusivity tensor, are obtained. solution of these equations permits the dye concentration profile for inside the cotton thread and in the dyeing batch to be obtained and the best conditions for the dyeing process to be chosen.
Estudo morfológico do ramo superficial do nervo radial
Folberg, Celso Ricardo;Ulson, Heitor JR;Scheidt, Rodrigo Benedet;
Revista Brasileira de Ortopedia , 2009, DOI: 10.1590/S0102-36162009000100011
Abstract: objective: study the morphology of the superficial branch of the radial nerve (sbrn) of the forearms and wrists of fresh adult human cadavers. methods: twenty three dissections were performed under 3.5x loupe magnification, histological sections of the nerve were obtained in 20 dissections for fascicle identification. results: the sbrn emerged, in average, at 8.65cm proximal to the radial styloid apophysis (rsa) between the brachioradialis (br) and extensor carpi radialis longus (ecrl) tendons. in 6/23 cases the sbrn emerged between an accessory br tendon and the main br tendon. the first branch of the sbrn arose at an average of 4.58 cm proximal to the rsa. a branch running across the rsa was found in 7/23 cases. at that level, the average number of branches crossing the wrist was 3.4. a fascicle count of the nerve and its first branch showed an average of 6.6 and 4.0 fascicles, respectively. conclusion: our anatomical findings are similar to those in the revised literature and contribute towards a better knowledge of the sbrn. great caution is required in surgical procedures such as percutaneous bone fixation of the distal 1/3 of the forearm and wrist and particularly, in those susceptible to sbrn injury, as in seven of the 23 cases the srbn ran directly accross the rsa. the authors recommend performing small longitudinal incisions down to the subcutaneous tissue, separating the nerve branches by blunt soft tissue dissection, with a delicate haemostat, before introducing the kirschner wires (minimally invasive procedures).
