RESUMO
Acquired cholesteatoma in children is an aggressive disease due to its rapid growth and high recurrence rate. The complications are divided into intra-and extratemporal complications or intracranial complication. Subperiosteal abscess is the most common extratemporal complication. It is most frequent in young children. However, there are also other associated complications described in the literature. Down syndrome patients have anatomical and functional predisposing factors that contribute to chronic cholesteatomatous otitis media. The prevalence is greater than 80 %. In this report, we present a case of subperiosteal abscess in an 8-year-old child with Down's syndrome. This abscess presented as a complication of an extended cholesteatoma and required inmediate surgery for resolution.
El colesteatoma adquirido en niños es una enfermedad agresiva debido a su rápido crecimiento y la alta tasa de recurrencia. Las complicaciones se dividen en dos grandes grupos: las relacionadas con el hueso temporal (dentro o fuera de él) y las complicaciones intracraneales. El absceso subperióstico es la complicación extratemporal más común y es más frecuente en los niños más pequeños. Los pacientes que padecen síndrome de Down tienen una prevalencia elevada (superior al 80 %) de otitis media con efusión, que puede estar determinada anatómicamente por la hipoplasia mediofacial con una nasofaringe estrecha y adenoides hipertrófica, junto a trastornos funcionales y mecánicos de la trompa auditiva. Se presenta un niño de 8 años con síndrome de Down que desarrolló un absceso subperióstico como complicación de un colesteatoma que requirió abordaje quirúrgico inmediato para su resolución.

Sensitivity to suffering of others is a core factor in social cohesion and evolutionary success. The emergence of such sensitivity may occur via two neuro-functional mechanisms. One is sharing the pain and distress of others, which relies on affective empathy. The other involves a caring concern for others' wellbeing, termed compassion. Both affective empathy and compassion are triggered by cues of pain and distress, exhibited by suffering targets. Yet, the mechanisms underlying distress processing in empathy and compassion are not clear. In the current research, we investigated synchrony with a target's distress, as a putative mechanism for continuous processing of distress cues. Participants viewed a video of a target in distress when given two different instructions: they were asked to continuously rate their distress in the affective empathy condition, or their feelings of care in the compassion condition. We used these dynamic ratings as well as participants' autonomic and facial responses to assess multi-channel synchrony with the target's self-rated distress fluctuations. Dynamic ratings and facial corrugator responses were significantly positively synchronized with the target's distress. For the corrugator responses, synchrony with the target was more pronounced than synchrony with participants' own ratings. Autonomic responses exhibited negative synchrony with the target's distress. Synchrony was higher in the affective empathy than in the compassion condition, across channels. These results point to the key role of subjective and physiological synchrony with the target's distress in empathic sharing of negative experiences. They also highlight the attenuation of embodied resonance with distress in compassionate experiences.

La actinomicosis es una infección causada por un bacilo anaerobio Gram-positivo, filamentoso, ramificado, no esporulado. Integra la flora habitual de la orofaringe y coloniza transitoriamente el tracto gastrointestinal, genital femenino y el árbol bronquial. Es poco frecuente en el hueso temporal. Por su semejanza a un hongo, es difícil su reconocimiento, lo que hace necesaria la sospecha clínica para obtener los cultivos apropiados en condiciones anaeróbicas en forma prolongada. Los hallazgos microscópicos típicos incluyen necrosis con gránulos de azufre amarillento y la presencia de filamentos que se asemejan a infecciones fúngicas. El tratamiento requiere de elevadas y prolongadas dosis de antibiótico con penicilina o amoxicilina, entre 6 y 12 meses. La duración de la terapia antimicrobiana podría ser reducida en pacientes que han sido operados quirúrgicamente. Se presenta, a continuación, un caso clínico de actinomicosis en el hueso temporal en un paciente pediátrico que requirió tratamiento quirúrgico para su resolución.
Actinomycosis is an infection caused by a Gram-positive, filamentous anaerobic bacillus. Mainly belonging to the human commensal flora of the oropharynx, it normally colonizes the human digestive and genital tracts and the bronchial tree. It is slightly frequent in the temporal bone. Bacterial cultures and pathology are the cornerstone of diagnosis, but particular conditions are required in order to get the correct diagnosis. Prolonged bacterial cultures in anaerobic conditions are necessary to identify the bacterium and typical microscopic findings include necrosis with yellowish sulfur granules and filamentous Gram-positive fungal-like pathogens. Patients with actinomycosis require prolonged (6- to 12-month) high doses of penicillin G or amoxicillin, but the duration of antimicrobial therapy could probably be shortened in patients in whom optimal surgical resection of infected tissues has been performed. A pediatric patient with actinomycosis in temporal bone who needed surgery resolution is reported.

Essential palatal myoclonus is a rare neurological disorder characterized by involuntary movements of the soft palate musculature causing objective-clicking tinnitus. The palatal myoclonus is classified in two forms, secondary and essential palatal myoclonus. Primary (essential) palatal myoclonus is the most common type in childhood. Normal computed tomography and magnetic resonance guide the diagnosis. Spontaneous resolution usually occurs in the essential type of palatal myoclonus.In this report, we present an 8-year-old child making rhythmic, rapid clicking noises from her throat with spontaneous resolution.

Personal space, defined as the distance individuals choose to maintain between themselves and others, is an indicator of affiliation and closeness. Most paradigms that measure personal space preferences involve explicit choice and therefore fail to examine the implicit aspects of such preferences. In the current study, we sought to investigate an implicit form of interpersonal space that is more closely related to real-life situations involving affiliation. We studied the effects of oxytocin (OT) on neural networks that involve affiliation and tested the impact on personal space preferences. In a double-blind placebo-controlled study, we asked participants to choose between two rooms that differed only in the distances between two stimuli. The stimuli were either social stimuli (two chairs) or non-social stimuli (table and plant). The behavioral results showed that OT caused participants to choose a closer space in social blocks but did not affect their choices in non-social blocks. Imaging results revealed an interaction between stimulus and treatment (OT/PL) in the dorsal striatum, an area that is related to approach motivation and is part of the reward circuitry. Specifically, OT increased activity in the dorsal striatum in the social blocks and decreased this activity in the non-social blocks. The results of the study strengthen the social salience theory regarding OT, indicating that OT does not uniformly affect all social responses and that context has a determining impact on our behavior.

The physical space individuals share is known as interpersonal space. As social creatures, people tend to approach others actively and explore the environment around them, opting for different space preferences with different people. In the current study, we sought to examine the role of oxytocin (OT) in regulating active social interpersonal space preferences. Contrary to previous studies that reported a preference for increased space following intranasal OT, we predicted that following OT administration individuals would exhibit increased active approach towards a protagonist. Accordingly, we measured active approach towards friends and strangers. The results indicated that OT increased social approach, particularly to strangers, suggesting that the OT system plays a major role in regulating social approach, depending on type of protagonist. The results are in line with the social salience and anxiety reduction hypotheses showing that OT increases approach to strangers.

Los abscesos retro y parafaríngeos son procesos infrecuentes aunque asociados con morbilidad significativa y potencial mortalidad. En los últimos años, se ha detectado un aumento de incidencia de estas infecciones, que se debe, principalmente, a una mayor disponibilidad de la tomografía computada y a mayor virulencia de los gérmenes (Streptococcus beta hemolítico del grupo A y Staphilococcus aureus meticilino resistente). Predominan en menores de 5 años. El tratamiento de los abscesos retro y parafaríngeos consiste en antibiótico endovenoso y, eventualmente, drenaje quirúrgico. Serían pasibles de tratamiento quirúrgico aquellos pacientes con abscesos mayores de 2 cm³, con dificultad respiratoria o mala respuesta al tratamiento antibiótico inicial. El objetivo de este reporte es presentar las características clínicas y el tratamiento de tres pacientes con abscesos profundos de cuello que se presentaron en Otorrinolaringología del Hospital de Niños Pedro de Elizalde en el período de un año.
Retropharyngeal and parapharyngeal abscesses are rare but associated with significant morbidity and potential mortality. In recent years, there has been an increase in the incidence of these infections, mainly due to a greater availability of computed tomography scan and a greater virulence of the germs (Group A b-hemolytic Streptococcus and methicillin-resistant Staphylococcus aureus). They predominate in children younger than 5 years. Treatment of retropharyngeal and parapharyngeal abscesses consists of an intravenous antibiotic and eventually surgical drainage. Surgical treatment is indicated in patients with abscesses greater than 2 cm³, with respiratory difficulty or poor response to initial antibiotic treatment. The aim of this study is to describe clinical features and treatment of three cases of deep neck abscesses presented at Hospital de Niños Pedro de Elizalde, Otorhinolaryngology Department in the period of one year.

Interpersonal space is a nonverbal indicator of affiliation and closeness. In this study we investigated the effects of oxytocin (OT), a neuropeptide known for its social role in humans, on interpersonal space. In a double blind placebo controlled study we measured the effect of intranasal OT on the personal distance preferences of different familiar (friend) and unfamiliar (stranger) protagonists. Behavioral results showed that participants preferred to be closer to a friend than to a stranger. Intranasal OT was associated with an overall distancing effect, but this effect was significant for the stranger and not for the friend. The imaging results showed interactions between treatment (OT, placebo) and protagonist (friend, stranger) in regions that mediate social behavior including the dorsomedial prefrontal cortex (dmPFC), a region associated with the mentalizing system. Specifically, OT increased activity in the dmPFC when a friend approached the participants but not when a stranger approached. The results indicate that the effect of OT on interpersonal space greatly depends on the participant's relationship with the protagonist. This supports the social salience theory, according to which OT increases the salience of social cues depending on the context.

Rhinosinusitis is a very common childhood condition. Osteomyelitis is an unusual complication, which mainly occurs in toddlers and young children. The most frequent etiologic agent is Staphylococcus aureus. Iniatially, it is characterized by fever, low eyelid edema, unilateral rhinorrhea and ipsilateral palatine edema. Subsequently, abscesses develop in the maxillar yuxtanasal and/or the dental alveolar area. Secondary, it can be complicated by sequestrations, spontaneous expulsion of dental pieces and/or fistula, as well as orbital and intracranial complications. The diagnosis is based on clinical findings and is confirmed by computed tomography findings. The treatment is clinical and surgical. Here we report a five year old child, with rhinosinusitis complicated by osteomyelitis of maxillary bone, mediated by a methicillin-resistant Staphylococcus aureus infection.
La rinosinusitis es una patología muy frecuente en la infancia. Entre sus complicaciones, se encuentra la osteomielitis, rara complicación que, cuando se presenta, ocurre, principalmente, en lactantes y niños pequeños. El agente etiológico más frecuente es el Staphylococcus aureus. Clínicamente, se manifiesta con fiebre alta, edema de párpado inferior, rinorrea unilateral y edema palatino ipsilateral; luego se agrega un absceso sobre el área maxilar yuxtanasal y/o sobre los alvéolos dentarios. Secundariamente, pueden desarrollarse secuestros, expulsiones espontáneas de piezas dentarias y trayectos fistulosos, así como complicaciones orbitarias y endocraneales. El diagnóstico es, sobre todo, clínico; se confirma con tomografia computada. El tratamiento es médico quirúrgico. Se presenta un niño de 5 años de edad con rinosinusitis complicada con osteomielitis del hueso maxilar, cuyo germen responsable fue el Staphylococcus aureus meticilino resistente.

La tuberculosis faríngea es una manifestación extrapulmonar infrecuente. En Argentina, se notificaron 1752 pacientes enfermos de tuberculosis menores de 19 años en el año 2012. Solo 12,15% teman localización extrapulmonar. Se presenta el caso de una adolescente que consultó por odinofagia y fiebre intermitente de 6 meses de evolución, sin respuesta al tratamiento antibiótico convencional. La radiografía de tórax presentaba infiltrado micronodulillar bilateral, por lo que la paciente se internó para estudiar y tratar. El resultado del examen directo de esputo para bacilos ácido-alcohol resistentes fue positivo y se inició tratamiento con cuatro drogas antituberculosas, con buena evolución y desaparición de los síntomas. Se obtuvo confirmación diagnóstica con el aislamiento de la Mycobacterium tuberculosis del cultivo de esputo. La tuberculosis faríngea presenta como principal motivo de consulta odinofagia y dificultad en la deglución de larga evolución. Por ello, se resalta la importancia de descartar tuberculosis ante toda faringitis sin respuesta al tratamiento convencional.
Pharyngeal tuberculosis is a rare extrapulmonary manifestation. In Argentina, the number of cases of tuberculosis reported in children under 19 years in 2012 was 1752. Only 12.15% had extrapulmonary manifestation. A case of a 17 year old girl with pharyngeal tuberculosis is reported. The patient presented intermittent fever and swallowing pain for 6 months, without response to conventional antibiotic treatment. Chest X-ray showedbilateral micronodular infiltrate, so hospitalization was decided to study and treat. The sputum examination for acid-fast resistant bacilli was positive and treatment with four antituberculous drugs was started, with good evolution and disappearance of symptoms. Diagnostic confirmation with the isolation of Mycobacterium tuberculosis in sputum culture was obtained. The main symptoms of pharyngeal tuberculosis are sore throat and difficulty in swallowing of long evolution. It is important to consider tuberculosis as differential diagnosis in patients with chronic pharyngitis unresponsive to conventional treatment.

Lichen planus pemphigoides is a rare autoimmune blistering disease that is characterized by evolution of vesico-bullous skin lesions in patients with active lichen planus. We describe a case of lichen planus pemphigoides in a 6-year-old boy and review the clinical and immunopathologic features of all reported cases of pediatric lichen planus pemphigoides. The mean age at onset of childhood lichen planus pemphigoides is 12 years with a male to female ratio of 3:1 and a mean lag-time between lichen planus and the development of lichen planus pemphigoides of 7.9 weeks. Vesiculo-bullous lesions were found on the extremities in all patients and there was palmoplantar involvement in about half of the cases. Direct and indirect immunofluorescence features were similar to those reported in adults. One patient had Western immunoblot data revealing antigens of 180, 230, and 200 kDa. Immunoelectron microscopy in two cases showed localization of immune deposition different from that in bullous pemphigoid. We found that topical corticosteroids or oral dapsone caused resolution of lichen planus pemphigoides without known relapse of blistering in four cases, suggesting that it might be possible to reserve oral corticosteroids as a second line of therapy in children with lichen planus pemphigoides.
