The modified Valsalva maneuver in hypopharynx CT scan / 临床耳鼻咽喉头颈外科杂志

Objective:To analyze the significance and factors influencing of CT scan under the modified Valsalva maneuver. Methods:Clinical data of 52 patients with hypopharyngeal carcinoma diagnosed from August 2021 to December 2022 were collected, all patients had calm breathing CT scan and modified Valsalva maneuver CT scan. Compare the exposure effect of the aryepiglottic fold, interarytenoid fold, postcricoid area, piriform fossa apex, posterior hypopharyngeal wall, and glottis with each CT scanning method. The effects of age, neck circumference, neck length, BMI, tumor site, and T stage on the exposure effect were analyzed. Results:In 52 patients, 50 patients（96.15%） completed CT scan at once time. The exposure effect of the CT scan under modified Valsalva maneuver in the aryepiglottic fold, interarytenoid fold, postcricoid area, piriform fossa apex, posterior hypopharyngeal wall was significantly better than CT scan under calm breathing（Z=-4.002, -8.026, -8.349, -7.781, -8.608, all P<0.01）, while CT scan under modified Valsalva maneuver was significantly worse in glottis than CT scan under calm breathing（Z=-3.625, P<0.01）. In the modified Valsalva CT scan, age had no obvious effect on the exposure effect. The exposure effect was better with long neck length, smaller neck circumference, smaller BMI and smaller T stage. The exposure of postcricoid carcinoma was better than pyriform sinus carcinoma and posterior hypopharyngeal wall carcinoma. But differences were not all statistically significant. Conclusion:The anatomical structure of the hypopharynx was clearly under CT scan with modified Valsalva maneuver, which clinical application is simple, but the effect of glottis was worse. The influence of age, neck circumference, neck length, BMI, and tumor T stage on the exposure effect still needs further investigation.

Neumotórax espontáneo bilateral en primigestante adolescente, reporte de un caso / Spontaneous bilateral pneumothorax in a primigestant adolescent, a case report

El neumotórax espontáneo es una patología extremadamente rara durante la gestación. Se define como la presencia de aire dentro de la cavidad pleural que puede generar principalmente dolor torácico y disnea. Esta patología tiene unas bajas incidencia y prevalencia en el embarazo, pero es relevante por una alta tasa de recurrencia, con un buen pronóstico para la madre y el feto si es tempranamente diagnosticada y oportunamente manejada. Se relaciona con factores de riesgo como las maniobras de Valsalva efectuadas durante el trabajo de parto, además de con comorbilidad como el tabaquismo, y con el biotipo longilíneo, entre otros, por lo que son muy importantes una adecuada anamnesis y la evaluación de la exploración física. El obstetra debe sospecharlo ante la clínica de dolor torácico asociado a disnea en gestantes en el trabajo de parto y el parto, y tenerlo en cuenta como diagnóstico diferencial. Es de vital importancia tener un manejo multidisciplinario compuesto por ginecoobstetra, internista, neumólogo y neonatólogo, incluido el apoyo por una unidad de cuidado intensivo para evitar complicaciones materno-perinatales que se puedan asociar al neumotórax espontáneo.

Spontaneous pneumothorax is an extremely rare pathology during pregnancy. It is defined as the presence of air inside the pleural cavity that can mainly generate chest pain and dyspnea. This pathology has a low incidence and prevalence in pregnancy, but a high rate of recurrence with a good prognosis for the mother and the fetus if it is diagnosed early and managed early. It is related to risk factors such as Valsalva maneuvers performed during labor, in addition to comorbidities such as smoking, longilinear biotype, among others, so it is very important to have an adequate history and evaluation of the physical examination. The obstetrician must be attentive to chest pain symptoms associated with dyspnea in pregnant women during labor and delivery, suspect this pathology and take it into account as a differential diagnosis. It is vitally important to have a multidisciplinary management composed of the gynecologist-obstetrician, internist, pulmonologist, neonatologist, including the support of an intensive care unit to avoid maternal-perinatal complications that may be associated with spontaneous pneumothorax.

Reparación de fractura aislada del mango del martillo con cemento ionomérico vidrioso autocurado / Repair of a malleus handle fracture using glass ionomer luting cement

Resumen La fractura aislada del mango del martillo es una entidad clínica poco habitual, pero frecuentemente subdiagnosticada. Lo fundamental es la sospecha clínica. El diagnóstico se confirma con la otoscopia neumática o la otomicroscopia con maniobra de Valsalva, en la cual se observa una movilidad anormal del mango del martillo. El rasgo de fractura se puede demostrar con tomografía computada de alta resolución o cone beam. Existen diferentes opciones de tratamiento como interposición de cartílago o uso de prótesis de reemplazo osicular así como cemento óseo. El cemento ionomérico vidrioso autocurado, muy utilizado en odontología, se ha usado en distintas cirugías otológicas con buenos resultados y biocompatibilidad. A nuestro saber no se ha usado en esta patología por lo que presentamos esta serie de tres casos en los cuales se ha usado esta novedosa técnica con buenos resultados clínicos.

Abstract Isolated fracture of the manubrium of the malleus is a rare clinical entity. Clinical suspicion is paramount. The usual clinical presentation is acute otalgia followed by tinnitus and fluctuating hearing loss after a brisk introduction and withdrawal of a finger into the external auditory canal. On physical examination, the eardrum looks normal on otoscopy. Only in pneumatic otoscopy or otomicroscopy with Valsalva an abnormal motility of the manubrium could bee seen. High-resolution computed tomography (CT) or cone beam CT is able to show the fracture line. Several treatment options have been proposed, such as interposition of bone or cartilage between the manubrium and the incus, total or partial ossicular replacement prosthesis; and the use of bone cement. Glass ionomer luting cement, with wide use in dentistry, has been used in several otological procedures with good biocompatibility and results, however, to our best knowledge, it has not been used to repair this type of fractures, so we present this novel material in three cases.

THE function and morphology study of eustachian tube based on sonotubometry and multi-slice spiral CT in normal subjects / 中华耳鼻咽喉头颈外科杂志

Objective: In order to assess ET more comprehensively, sonotubometry (STM)combined with CT images were applied to investigate the opening features of eustachian tube (ET) in normal subjects. STM was also used as a monitor training ET opening maneuver and optimizing CT scan parameters. Methods: Following ET opening training monitored by STM, STM data of ET opening duration and maximum sound pressure from 13 healthy volunteers (10 males and 3 females, 22 to 26 years old) were acquired using maneuvers of swallowing and Valsalva in standing and supine positions. Two trials of CT scan, setting A (slice thickness 6.0 mm, manually simulated to 0.6 mm, reconstruction thickness 0.6 mm) for normal and Valsalva scans and setting B(slice thickness 0.4 mm,reconstruction thickness 0.4 mm)for Valsalva scan, were conducted in each subject. The bone area and cartilage area of ET were measured respectively in reconstructed CT images. Statistical software SPSS 19.0 was employed in data analysis. Results: The duration of ET opening and maximum sound pressure by Valsalva were longer and stronger than those by swallowing in both positions. For Valsalva maneuver, standing position resulted in longer ET opening duration compared to supine position (P<0.05). Under setting A, ET cartilage area was measured larger by Valsalva scan than by normal scan (P<0.05). By Valsalva scan, setting A captured larger ET cartilage area compared to setting B (P<0.05). CT setting B resulted in longer scan time in comparison to setting A (P<0.05). Conclusions: Techniques of STM in supine position plus CT scan under setting A can be combined by Valsalva passive ET opening. Not only the invisible ET lumen through routine CT scan can be illustrated, but also relevant ET open-close process is shown, therefore, this study provides the technique for ET research of function and structure.

Status epilepticus due to cerebral air embolism after the Valsalva maneuver

BACKGROUND: Cerebral air embolism is uncommon but potentially causes catastrophic events such as cardiac damage or even death. However, due to a low overall incidence, it may go undiagnosed. CASE REPORT: A 56-year-old man with a medical history of right upper lobectomy due to lung cancer showed changes in mental status after the Valsalva maneuver, followed by status epilepticus during admission. Brain and chest computed tomography showed cerebral air embolism and accidental pneumothorax in the right major fissure. After antiepileptic drug infusion and oxygen therapy, he recovered completely. CONCLUSION: Since cerebral air embolism may result in fatal outcomes, it should be suspected in patients with sudden neurological deterioration after routine medical procedures.

Cardiac autonomic neuropathy in nonobese young adults with type 1 diabetes

PURPOSE: The aim of this study was to evaluate the prevalence and risk factors for cardiac autonomic neuropathy (CAN) in nonobese nonobese young type 1 diabetes mellitus (T1DM) patients without micro- or macrovascular complications. METHODS: CAN was assessed in 95 patients with T1DM, aged 18–29 years, using standard cardiovascular reflex tests – heart rate response to deep breathing, standing, and the Valsalva maneuver and blood pressure response to standing. Furthermore, power spectral analyses of overall heart rate variability (HRV), standard deviation of NN intervals (SDNN), and total power (TP) were tested with DiCAN. CAN was defined as abnormal results for at least 1 of the 4 cardiovascular reflex tests. RESULTS: The prevalence of CAN was 12.6%. The frequency of one and 2 abnormal reflex tests was 10.5% and 2.1%, respectively. No significant differences were observed in age, sex, mean hemoglobin A(1c) (HbA(1c)) level, and duration of diabetes with respect to presence of CAN. Patients with CAN exhibited lower overall HRV parameters (SDNN and TP) compared with those without CAN even though there was no statistical significance. In multivariable analyses, higher mean HbA(1c) level was significantly associated with lower overall HRV (β=-44.42, P=0.002 for SDNN and β=-2.82, P<0.001 for TP). CONCLUSION: CAN can be detected in 12.6% of young adult T1DM patients even without other micro- or macrovascular complications. Glycemic control is the main determinant to maintain overall HRV and prevent CAN.

Symptomatic Sinus Pericranii with Adult Onset Headache: A Case Report with Pathologic Perspective

Sinus pericranii (SP) is a rare vascular anomaly of the scalp that consists of an abnormal pericranial venous channel connected to adjacent dural venous sinuses. Most SP are asymptomatic and are found in the pediatric age group. We aim to report a case of symptomatic SP in adult and describe the clinical, radiological, and pathohistological findings to help understand and differentiate this lesion from other scalp lesions. A 40-year-old man with a scalp mass was admitted to our hospital complaining of headache. The lesion enlarged when the patient was in a recumbent position or during Valsalva maneuver. The radiologic imaging suggested its diagnosis as an accessory type of SP with bone erosion. Surgical resection and cranioplasty were successfully performed, and the related headache also gradually subsided. At the 3-year follow-up, there was no recurrence on magnetic resonance imaging.

Arnold-Chiari Type 1 Malformation Mimicking Benign Paroxysmal Positional Vertigo / 대한평형의학회지

Arnold-Chiari malformation type 1 is a congenital disease characterized by herniation of the cerebellar tonsils through the foramen magnum. Most common clinical symptom is pain, including occipital headache and neck pain, upper limb pain exacerbated by physical activity or valsalva maneuvers. Various otoneurological manifestations also occur in patients with the disease, which has usually associated with dizziness, vomiting, dysphagia, poor hand coordination, unsteady gait, numbness. Patients with Arnold-Chiari malformation may develop vertigo after spending some time with their head inclined on their trunk. Positional and down-beating nystagmus are common forms of nystagmus in them. We experienced a 12-year-old female who presented complaining of vertigo related to changes in head position which was initially misdiagnosed as a benign paroxysmal positional vertigo.

Choroidal Effusion after Consecutive General Anesthesia

PURPOSE: To report a case of extensive choroidal effusion following the Valsalva maneuver under consecutive general anesthesia. CASE SUMMARY: A 41-year-old man who underwent panretinal photocoagulation with proliferative diabetic retinopathy had pars plana vitrectomy and endolaser photocoagulation under general anesthesia due to vitreous hemorrhage. Urology cooperated as the patient had hematuria; the day after the operation, he was transferred to the urology department. Two days after vitrectomy, the patient had an urgent transurethral bladder tumor resection under general anesthesia with suspicion of bladder tumor. At 6 days postoperatively, extensive choroidal effusion was observed from 8 to 10 o'clock on fundus examination and ultrasonography. On day 23 after urological surgery, the choroidal effusion had disappeared without treatment. CONCLUSIONS: Consecutive general anesthesia requires caution, as it is not only burdensome to the body as a whole but may also cause choroidal effusion in the eye.

Examen clínico y maniobra de valsalva en la insuficiencia cardíaca / Clinical examination and the Valsalva maneuver in heart failure

La evaluación de la congestión en pacientes con insuficiencia cardíaca y fracción de eyección reducida (ICFEr) resulta relevante y estrechamente vinculada al curso clínico. El agregado del comportamiento de la presión arterial durante la maniobra de Valsalva en la cabecera del paciente (VAL) podría mejorar la evaluación clínica de congestión cuando la comparamos con los niveles de NT-proBNP y la estimación de la presión media en la aurícula izquierda por Doppler cardíaco, como subrogantes de congestión. Se realizó un examen clínico con el VAL, un examen de laboratorio y un Doppler cardíaco en 69 pacientes ambulatorios con insuficiencia cardíaca y fracción de eyección ≤ 40% en ritmo sinusal. El score de Framingham ≥ 2 (SFr ≥ 2) se empleó para evaluar congestión clínica. VAL fue clasificado como normal o anormal, el NT-proBNP como bajo (< 1000 pg/ml) o alto (≥ 1000 pg/ml) y la relación entre la velocidad del llenado ventricular rápido y la velocidad del Doppler tisular (E/e') como baja < 15 o alta ≥ 15. Se halló que 13/27 pacientes con SFr ≥ 2 tenían NT-proBNP alto (sensibilidad 62%, especificidad 70% y razón de verosimilitud positiva [LR+] de 2.08, p = 0.01). El agregado del VAL al SFr ≥ 2 mejoró la exactitud diagnóstica (sensibilidad 100%, especificidad 64% y LR+ 2.8 p = 0.0004). Comparado con la E/e', SFr ≥ 2 con VAL anormal mostró sensibilidad 86%, especificidad 56% y LR + 1.86 (p = 0.03). En conclusión, el agregado del comportamiento de la presión durante la maniobra de Valsalva podría mejorar la evaluación clínica de la congestión en la insuficiencia cardíaca.

Congestion in heart failure patients with reduced ejection fraction (HFrEF) is relevant and closely linked to the clinical course. Bedside blood pressure measurement during the Valsalva maneuver (Val) added to clinical examination may improve the assessment of congestion when compared to NT-proBNP levels and left atrial pressure (LAP) estimation by Doppler echocardiography, as surrogate markers of congestion in HFrEF. A clinical examination, LAP and blood tests were performed in 69 HFrEF ambulatory patients with left ventricular ejection fraction ≤ 40% and sinus rhythm. Framingham Heart Failure Score (HFS) was used to evaluate clinical congestion; Val was classified as normal or abnormal, NT-proBNP was classified as low (< 1000 pg/ml) or high (≥ 1000 pg/ml) and the ratio between Doppler early mitral inflow and tissue diastolic velocity was used to estimate LAP and was classified as low (E/e'< 15) or high (E/e' ≥ 15). A total of 69 patients with HFrEF were included; 27 had a HFS ≥ 2 and 13 of them had high NT-proBNP. HFS ≥ 2 had a 62% sensitivity, 70% specificity and a positive likelihood ratio of 2.08 (p=0.01) to detect congestion. When Val was added to clinical examination, the presence of a HFS ≥ 2 and abnormal Val showed a 100% sensitivity, 64% specificity and a positive likelihood ratio of 2.8 (p = 0.0004). Compared with LAP, the presence of HFS ≥ 2 and abnormal Val had 86% sensitivity, 54% specificity and a positive likelihood ratio of 1.86 (p = 0.03). In conclusion, an integrated clinical examination with the addition Valsalva maneuver may improve the assessment of congestion in patients with HFrEF.

Prevalencia de hiperactividad del detrusor secundaria a valsalva en mujeres sometidas a estudio urodinámico para estudio de incontinencia urinaria ó síndrome de vejiga hiperactiva / Prevalence of detrusor hyperactivity secondary to valsalva in women undergoing urodynamic study for study of urinary incontinence or overactive bladder syndrome

La Incontinencia Urinaria (IU) y el Síndrome de Vejiga Hiperactiva (VHA) son problemas urológicos comunes en la población femenina. Éstos pueden ser evaluados mediante el Estudio Urodinámico. Dentro de los diagnósticos urodinámicos destaca la Incontinencia Urinaria de Esfuerzo (IUE), caracterizada por pérdidas de orina durante maniobras de valsalva y la Hiperactividad del Detrusor (HAD), dada por las contracciones involuntarias del Detrusor durante la fase de llene cistométrica. Existe además una entidad poco descrita, la Hiperactividad del Detrusor secundaria a Valsalva (HAD-V), que es aquella caracterizada por contracciones involuntarias del detrusor que se generan precisamente después de una maniobra de valsalva, simulando clínicamente una falsa Incontinencia Urinaria de Esfuerzo. El Objetivo del presente Estudio es determinar la prevalencia de la Hiperactividad del Detrusor secundaria a Valsalva en mujeres sometidas a estudio urodinámico por síntomas de Incontinencia Urinaria y/ó Síndrome de Vejiga Hiperactiva. MATERIALES Y MÉTODOS: Un mismo operador realizó estudio urodinámico por síntomas de IU y/o VHA a un total de 247 pacientes entre los años 2011 y 2018. La urodinamia fue realizada según las recomendaciones de la Sociedad Internacional de Continencia. Se clasificó a las pacientes en grupos según su sintomatología al momento de realizar la urodinamia: IUE pura, VHA pura, Incontinencia Urinaria Mixta (IUM) con predominio de esfuerzo, IUM con predominio de urgencia e IUM real. Se realizó evaluación de los registros urodinámicos asociando el hallazgo de HAD-V a cada grupo de sintomatología. RESULTADOS: De un total de 247 pacientes, el 20,2 po rciento desarrolló HAD-V. 24 pacientes con IUE pura, de las cuales el 12,5 por ciento presentó HAD-V 69 pacientes con VHA, de las cuales el 13 por ciento presentó HAD-V 18 pacientes con IUM con predominio de IUE, de las cuales 22,5 por ciento presentó HAD-V 19 pacientes con IUM con predominio de IUU, de las cuales 15,7 por ciento desarrolló HAD-V 117 pacientes con IUM real, de las cuales el 26,5 por ciento desarrolló HAD-V CONCLUSIONES: La HAD-V es una entidad poco considerada y descrita. Su prevalencia no es menor, y es importante considerarla, porque un buen diagnóstico de ésta podría ayudar a tomar mejores decisiones terapéuticas en pacientes con síntomas de IU ó VHA.(AU)

Urinary Incontinence (UI) and Overactive Bladder Syndrome (OAB) are common urological problems in the female population. These can be evaluated through the Urodynamic Study. Urodynamic diagnoses include Urinary Stress Incontinence (SUI), characterized by urine loss during valsalva maneuvers and Detrusor Hyperactivity (DH), given by the involuntary contractions of the Detrusor during the cystometric filling phase. There is also a little described entity, the Detrusor Hyperactivity secondary to Valsalva (HAD-V), which is characterized by involuntary detrusor contractions that are generated precisely after a valsalva maneuver, simulating clinically a false Urinary Stress Incontinence. The objective of this study is to determine the prevalence of Detrusor Hyperactivity secondary to Valsalva in women undergoing urodynamic study due symptoms of Urinary Incontinence and / or Overactive Bladder Syndrome. MATERIALS AND METHODS: The same operator performed a urodynamic study due to UI and / or OAB symptoms in a total of 247 patients between 2011 and 2018. Urodynamics was performed according to the recommendations of the International Continence Society. The patients were classified into groups according to their symptoms at the time of performing urodynamics: pure SUI, pure OAB, mixed urinary incontinence (IUM) with predominance of stress, predominantly urgency IUM and real IUM. An evaluation of the urodynamic records was made, associating the finding of HAD-V to each group of symptoms. RESULTS: Of a total of 247 patients, 20.2 pertcent developed HAD-V. 24 patients with pure SUI, of which 12.5 pertcent presented HAD-V 69 patients with OAB, of which 13 pertcent presented HAD-V 18 patients with IUM with predominance of SUI, of which 22.5 pertcent presented HAD-V 19 patients with IUM with predominance of urgency, of which 15.7 pertcent developed HAD-V 117 patients with real IUM, of which 26.5 % developed HAD-V CONCLUSIONS: The HAD-V is a little considered and described entity. Its prevalence is not minor, and it is important to consider it, because a good diagnosis of it could help to make better therapeutic decisions in patients with symptom of UI or OAB.(AU)

Evaluation of efficacy of Valsalva maneuver for attenuating propofol injection pain: a prospective, randomized, single blind, placebo controlled study / 대한마취과학회지

BACKGROUND: Pain on injection is a limitation with propofol use. The effect of the Valsalva maneuver on pain during propofol injection has not been studied. This maneuver reduces pain through the sinoaortic baroreceptor reflex arc and by distraction. We aimed to assess the efficacy of the Valsalva maneuver in reducing pain during propofol injection. METHODS: Eighty American Society of Anesthesiologists class I adult patients undergoing general anesthesia were enrolled and divided into two groups of 40 each. Group I (Valsalva) patients blew into a sphygmomanometer tube raising the mercury column up to 30 mmHg for 20 seconds, while Group II (Control) patients did not. Anesthesia was induced with 1% propofol immediately afterwards. Pain was assessed on a 10-point visual analog scale (VAS), where 0 represented no pain, and 10, the worst imaginable pain, and a 4-point withdrawal response score, where 0 represented no pain, and 3, the worst imaginable pain. Scores were presented as median (interquartile range). RESULTS: We analyzed the data of 70 patients. The incidence of pain was significantly lower in the Valsalva than in the control group (53% vs 78%, P = 0.029). The withdrawal response score was significantly lower in the Valsalva group (1.00 [0.00-1.00] vs 2.00 [2.00-3.00], P < 0.001). The VAS score was significantly lower in the Valsalva group (1.00 [0.00-4.00] vs 7.00 [6.25-8.00], P < 0.001). CONCLUSIONS: A prior Valsalva maneuver is effective in attenuating injection pain due to propofol; it is advantageous in being a non-pharmacological, safe, easy, and time-effective technique.

Association between Magnetic Resonance Imaging Findings of the Pelvic Floor and de novo Stress Urinary Incontinence after Vaginal Delivery

OBJECTIVE: The study aimed to evaluate the contributions of levator ani muscle (LAM) injury, vesical neck movement, urethral length and mobility, and urethral sphincter dysfunction observed on magnetic resonance imaging (MRI) towards stress urinary incontinence (SUI) after vaginal delivery. MATERIALS AND METHODS: Fifty primiparous women after 6 months of delivery (15 with SUI and 35 without) and 35 nulliparous as continent controls underwent MRI at rest and Valsalva maneuver. A published levator ani scoring system was used to characterize morphological changes of LAM. The severity of the injury was divided into three categories as none, minor, and major. A series of common parameters including levator plate angle, iliococcygeal angle, and levator hiatus were used to describe the functional conditions of LAM. Urethral mobility was defined based on the rotation of the urethra between Valsalva and rest status. Vesical neck movement was evaluated by its distance to the pubococcygeal line. Urethral sphincter dysfunction was defined as the widening of the proximal urethra and/or funneling at the urethrovesical junction during Valsalva. RESULTS: Primiparous incontinent (PI) women had additional major levator ani defects (33.3% vs. 17.1%) while less minor defects (0.7% vs. 31.4%) than primiparous continent (PC) women. Vesical neck downward movement in PI women was more obvious than PC women (28.5 mm vs. 24.2 mm, p = 0.006). Urethral mobility was more active in primiparous women than in nulliparous continent controls (57.4 vs. 52.4), whereas no difference was observed on urethral mobility in the primiparous group (p = 0.25). Urethral sphincter dysfunction and funneling were present in 80% of PI women versus 22.9% in PC women (p < 0.001). CONCLUSION: The MRI findings revealed that de novo SUI was associated with major LAM injury, vesical neck downward movement as well as urethral sphincter dysfunction. Vesical neck funneling on sagittal images can be treated as a valuable predictor for SUI. The intervention for the PI should focus on the elevation of vesical neck, rehabilitation of LAM as well as recovery of the urethral sphincter muscle.

Evaluation of Adrenergic Function: Tilt-Table and Valsalva Test / 대한평형의학회지

Orthostatic dizziness is a common dizziness syndrome characterized by nonvertiginous lightheadedness when patients rise to stand from a sitting or supine position. Orthostatic dizziness is commonly believed to derive from orthostatic hypotension (OH) or postural tachycardia syndrome (POTS). Tilt-table test and Valsalva maneuver are standardized methods for evaluating of adrenergic autonomic function and essential for diagnosis of OH and POTS. We described the guidelines and interpretations of the tilt-table test and Valsalva maneuver.

Assessment of Eustachian tube function in patients with tympanic membrane retraction and in normal subjects / Avaliação da função da tuba de Eustáquio em pacientes com retração de membrana timpânica e em indivíduos normais

Abstract Introduction The diagnosis of Eustachian tube dysfunctions is essential for better understanding of the pathogenesis of chronic otitis media. A series of tests to assess tube function are described in the literature; however, they are methodologically heterogeneous, with differences ranging from application protocols to standardization of tests and their results. Objective To evaluate the variation in middle ear pressure in patients with tympanic membrane retraction and in normal patients during tube function tests, as well as to evaluate intra-individual variation between these tests. Methods An observational, contemporary, cross-sectional study was conducted, in which the factor under study was the variation in middle ear pressure during tube function tests (Valsalva maneuver, sniff test, Toynbee maneuver) in healthy patients and in patients with mild and moderate/severe tympanic retraction. A total of 38 patients (76 ears) were included in the study. Patients underwent tube function tests at two different time points to determine pressure measurements after each maneuver. Statistical analysis was performed using SPSS software, version 18.0, considering p-values <0.05 as statistically significant. Results Mean (standard deviation) age was 11 (2.72) years; 55.3% of patients were male and 44.7% female. The prevalence of type A tympanogram was higher among participants with healthy ears and those with mild retraction, whereas type C tympanograms were more frequent in the moderate/severe retraction group. An increase in middle ear pressure was observed during the Valsalva maneuver at the first time point evaluated in all three groups of ears (p = 0.012). The variation in pressure was not significant either for the sniff test or for the Toynbee maneuver at the two time points evaluated (p ≥ 0.05). Agreement between measurements obtained at the two different time points was weak to moderate for all tests in all three groups of ears, and the variations in discrepancy between measurements were higher in ears with moderate/severe tympanic retraction. Conclusion In this study population, the mean pressure in the middle ear showed significant variation only during the Valsalva maneuver at the first time point evaluated in the three groups of ears. Normal ears and those with mild retraction behaved similarly in all tests. The tested maneuvers exhibited weak to moderate intra-individual variation, with the greatest variation occurring in ears with moderate/severe retraction.

Resumo Introdução O diagnóstico das disfunções da tuba auditiva é essencial para o melhor entendimento da patogênese da otite média crônica. A literatura descreve uma série de testes que avaliam a função tubária; contudo, tais exames são metodologicamente heterogêneos, com diferenças que variam desde os protocolos de aplicação até a padronização dos exames e seus resultados. Objetivo Avaliar a variação na pressão na orelha média em pacientes com retração da membrana timpânica e em indivíduos normais durante os testes de função tubária e também avaliar a variação intraindividual desses testes. Método Estudo observacional do tipo transversal e contemporâneo, no qual o fator em estudo foi a variação na pressão na orelha média durante os testes de função tubária (manobra de Valsalva, Sniff Test e manobra de Toynbee) em indivíduos normais e em pacientes com retrações timpânicas leves e moderadas/graves. Foram incluídos 38 pacientes (76 orelhas). Os pacientes foram submetidos, em dois momentos diferentes, a testes de função tubária para determinar as medidas de pressão após cada manobra. A análise estatística foi feita com o programa SPSS, versão 18.0, e consideramos como estatisticamente significativos os valores de p < 0,05. Resultados A média ± desvio padrão da idade foi de 11 ± 2,72 anos; 55,3% dos pacientes eram do gênero masculino e 44,7% do feminino. A prevalência de curvas timpanométricas do tipo A foi mais alta entre os participantes com orelhas normais e naqueles com retrações leves, enquanto as curvas timpanométricas do tipo C foram mais frequentes no grupo com retrações moderadas/graves. Observamos pressões aumentadas na orelha média durante a manobra de Valsalva no primeiro momento da avaliação nos três grupos de orelhas (p = 0,012). A variação na pressão não foi significativa para o Sniff Test, nem para a manobra de Toynbee nos dois momentos de avaliação (p ≥ 0,05). Consideramos que a concordância entre as determinações obtidas nos dois momentos diferentes foi fraca a moderada para todos os testes nos três grupos de orelhas e as variações em termos de discrepância entre as medidas foram maiores nas orelhas com retrações timpânicas moderadas/graves. Conclusão Na população estudada, a média das pressões na orelha média apresentou variação significante apenas durante a manobra de Valsalva no primeiro momento de avaliação, nos três grupos de orelhas. As orelhas normais e aquelas que apresentavam retração leve se comportaram de maneira similar nos testes. As manobras testadas exibiram uma variação intraindividual fraca a moderada e a maior variação ocorreu nas orelhas com retrações moderadas/graves.

Defeito do septo átrio ventricular em adulto portador de trissomia do 21 / Case report defect of the septure ventricular atrial in adult trissomy carrier of 21

Introdução: Dos pacientes com Síndrome de Down que possuem cardiopatias congênitas, metade possuem defeitos no septo atrioventricular, em associação de comunicação interatrial, comunicação interventricular e a persistência do canal arterial. Descrição do caso: M.N.S,42 anos, portador de trissomia do 21. Encaminhado para a cardiologia,dia 07/09/16, para realização do cateterismo cardíaco após dor torácica recorrente e sopro sistólico. Na admissão, referiu precordialgia, com intensidade forte e duração de um dia, sem irradiações e fatores desencadeantes. Possui histórico de internações recorrentes de dor precordial e história familiar marcante de cardiopatias. Na avaliação clínica, encontrou-se sopro sistólico panfocal acentuado pela manobra de Rivero-Carvallo e diminuído com a manobra de Valsalva, confirmando sobrecarga de câmaras direitas. Realizou-se CATE de câmaras direitas e esquerdas no dia 09/09, onde conclui-se a presença de defeito septo AV de forma intermediária, hipertensão arterial pulmonar,hiperfluxo pulmonar,dilatação moderada da artéria pulmonar, aumento das dimensões do átrio esquerdo e constatou-se que o retorno venoso dáse para átrio esquerdo por uma comunicação interatrial ampla. Foi submetido à correção cirúrgica no dia 19/09/16, onde foi realizado plastia da valva mitral, correção da comunicação interatrial ostium primum com remendo pericárdico bovino e o fechamento do forame oval. Após a cirurgia, foi encaminhado para o CTI, onde permaneceu estável, sendo extubado no dia 21/09. Recebeu alta do CTI no dia 26/09 e encaminhado para a enfermaria para cuidados pós-cirúrgicos. Conclusão: É possível concluir que o despreparo de pequenos centros urbanos faz com que o serviço de saúde se direcione para os grandes centros urbanos e como muitas vezes isso não é possível, o diagnóstico e a terapêutica se dão tardiamente.

Introduction: Of the patients with Down syndrome who have congenital heart defects,half have defects in the atrioventricular septum,in the association of atrial septal defect, ventricular septal defect and persistence of the ductus arteriosus. Case description: MNS,42 years old,with trisomy 21. Referred to cardiology,day 07/09/16, to perform cardiac catheterization after recurrent chest pain and systolic murmur. On admission, he reported precordialgia,with strong intensity and duration of one day, without irradiation and triggering factors. He has a history of hospitalizations recurrence of precordial pain and marked family history of cardiopathies. In the clinical evaluation, a panfocal systolic murmur accentuated by the Rivero-Carvallo maneuver and decreased with the Valsalva maneuver, confirming overhead of right chambers. CATE of right chambers and on the 09/09, where the presence of an AV septal defect is found in pulmonary arterial hypertension, pulmonary hyperflow, moderate dilation of the pulmonary artery, enlargement of the left atrium, and venous return to the left atrium by extensive atrial septal defect. It was submitted to surgical correction on day 19 / 09, where mitral valve repair was performed,correction of the ostium primum atrial septal defect with bovine pericardial patch, and closure of the oval foramen. After surgery, the patient was referred to the ICU where he remained stable and was extubated on September 21. He was discharged from the ICU on September 26 and was sent to the ward for post-surgical care. Conclusion: It is possible to conclude that the lack of preparation of small urban centers causes the health service to be directed to large urban centers and how often this not possible, diagnosis and therapy are delayed.

The Effect of Mastoidectomy Combined with Tympanoplasty Type I on Postoperative Hearing in Chronic Otitis Media Patients Older than 65 Years / 대한이비인후과학회지

BACKGROUND AND OBJECTIVES: Although canal wall up mastoidectomy (CWUM) has been performed frequently as a treatment for chronic otitis media (COM), the necessity of CWUM for non-cholesteatomatous COM (NCCOM) is still controversial. Since elderly people often have systemic problems, there is a high likelihood of side effects after general anesthesia, so it is important to judge the necessity of mastoidectomy. The purpose of this study was to investigate the effect of CWUM for the treatment of NCCOM in patients over 65 years of age. SUBJECTS AND METHOD: Forty-two cases of CWUM with tympanoplasty type I performed as a treatment for NCCOM from 2007 through 2016 were reviewed retrospectively. Pure tone audiometry was performed preoperatively and postoperatively, and preoperative temporal bone CT was used to evaluate the mastoid status. The valsalva maneuver (VM) was used to evaluate the eustachian tube function. RESULTS: The total number of patients was 42 and the success rate of eardrum repair was 92.8%. Comparison of hearing results taken preoperatively and postoperatively showed significant hearing improvement in both air conduction and air-bone gap. When hearing results were compared according to the mastoid status and the response of VM, there were no significant differences. CONCLUSION: Mastoidectomy combined with tympanoplasty type I showed a high success rate of ear drum repair and good hearing improvement, with no critical side effects. Therefore, mastoidectomy does not need to be limited by one's old age. Adequate mastoidectomy after proper consideration of the mastoid status will be helpful in the treatment of the disease.
