A review of arterial thoracic outlet syndrome.

Arterial thoracic outlet syndrome (TOS) is a condition in which anatomic abnormalities in the thoracic outlet cause compression of the subclavian or, less commonly, axillary artery. Patients are usually younger and typically have an anatomic abnormality causing the compression. The condition usually goes undiagnosed until patients present with signs of acute or chronic hand or arm ischemia. Workup of this condition includes a thorough history and physical examination; chest x-ray to identify potential anatomic abnormalities; and arterial imaging, such as computed tomographic angiography or duplex to identify arterial abnormalities. Patients will usually require operative intervention, given their symptomatic presentation. Intervention should always include decompression of the thoracic outlet with at least a first-rib resection and any other structures causing external compression. If the artery is identified to have intimal damage, mural thrombus, or is aneurysmal, then arterial reconstruction is warranted. Stenting should be avoided due to external compression. In patients with symptoms of embolization, a combination of embolectomy, lytic catheter placement, and/or therapeutic anticoagulation should be done. Typically, patients have excellent outcomes, with resolution of symptoms and high patency of the bypass graft, although patients with distal embolization may require finger amputation.

Endoscopically assisted transaxillary release of the scalene muscles for thoracic outlet syndromes: a comparison with or without first rib resection.

OBJECTIVES: There are several surgical techniques for thoracic outlet syndrome (TOS). However, there have been no reports of endoscopically assisted transaxillary release of the anterior and middle scalene muscles (EATRS), leaving the first rib intact for TOS. We hypothesized that EATRS would achieve a good Quick Disability of the Arm, Shoulder and Hand score. This study aims to present our experience with a new technique for TOS using endoscopy. METHODS: We chose two surgeries depending on the patient's TOS condition. If the costoclavicular space was under 12 mm, we selected endoscopically assisted transaxillary first rib resection (EAFRR). If the costoclavicular space was over 12 mm, we selected EATRS. Between January 2021 and December 2022, 31 consecutive surgeries for TOS were performed in our institution. Twenty-five patients underwent EAFRR, and six (19%) underwent EATRS. Since July 2022, EAFRR has been performed under differential lung ventilation. RESULTS: Complete and almost complete relief was achieved in 24 patients (77%), and partial relief was conducted in seven patients (23%) at a mean of 19.7 months after surgery. The symptoms improved in all cases. Intraoperative pneumothorax did not occur, and no other complications were observed. Both EAFRR and EATRS were effective and safe surgeries for TOS. Operative time was significantly shorter in EATRS than in EAFRR. CONCLUSIONS: We first report EATRS surgery for TOS. EATRS is indicated for patients whose costoclavicular space is preserved before surgery. Good surgical results were obtained after surgery for this indication.

Cortical Hand Knob Paradoxical Thromboembolic Stroke in an Adolescent with Secundum Atrial Septal Defect and Paget-Schroetter Syndrome.

Venous thoracic outlet syndrome (vTOS) is an increasingly recognized diagnosis in young patients in which the subclavian vein is compressed within the costoclavicular space. With repetitive compression, thrombosis can develop and has been referred to as "effort thrombosis" or the Paget-Schroetter syndrome. Here, we present a 16-year-old boy with vTOS who presented with acute ischemic stroke (AIS) in the hand knob region of precentral gyrus due to paradoxical embolus in the setting of atrial septal defect.

[Syndromic approach in migrant patients: Fever, diarrhea, anemia, eosinophilia and chronic cough]. / Abordaje sindrómico en el paciente inmigrante: fiebre, diarrea, anemia, eosinofilia y tos crónica.

Migrant patients share the same diseases as natives, but biological or environmental differences may lead to distinct prevalence and manifestations of certain syndromes. Some common conditions in Primary Care stand out, such as fever, diarrhea, anemia, eosinophilia, and chronic cough, where it is important to have a special consideration. Fever may indicate a serious imported illness, and malaria should always be ruled out. Diarrhea is generally of infectious origin, and in most cases, management is outpatient. Anemia may indicate malnutrition or malabsorption, while eosinophilia may indicate a parasitic infection. Lastly, chronic cough may be a sign of tuberculosis, especially in immigrants from endemic areas. Family medicine holds a privileged position for the comprehensive, culturally sensitive, and person-centered approach to these conditions.

Intra- and Interpersonal Dimensions of Orthorexia: Preliminary Development and Validation of an Intra- and Interpersonal Effects Scale for Orthorexia.

Orthorexia nervosa (ON) is a disorder characterized by dietary restrictions and an obsessive focus on "healthy" eating. The present study analyzes two aspects of ON. One related to the inner experiences of the individual (intrapersonal). The other concerns the impact of ON on interpersonal relationships (interpersonal). The developed scale was named the Intra- and Interpersonal Effects Scale of Orthorexia (IIESO). The analysis showed an average correlation between the INTER and INTRA factors (r = 0.46). Both the INTER and INTRA scales correlated strongly with both subscales of the TOS but weakly with the ORTO-R score. Females obtained higher scores on the INTER scale (p < 0.01), while no differences were shown for the INTRA subscale or the overall scale score (p < 0.01). Subjects using supplements had higher mean scores on the INTER and INTRA subscales and for the total score. Among the analyzed results, the greatest strength effect was shown for the total score on the IIESO scale (INTER+INTRA) and the TOS scale. The questionnaires used to date have not distinguished between behaviors from interpersonal and intrapersonal perspectives. Research on these dimensions could expand our knowledge of the disorder and refine diagnostic criteria.

Crystal structures of sulfonamide protected bicyclic guanidines: (S)-8-{[(tert-butyl-dimethyl-sil-yl)-oxy]meth-yl}-1-[(2,2,4,6,7-penta-methyl-2,3-di-hydro-benzo-furan-5-yl)sulfon-yl]-1,3,4,6,7,8-hexa-hydro-2H-pyrimido[1,2-a]pyrimidin-1-ium tri-fluoro-methane-sulfonate and (S)-8-(iodo-meth-yl)-1-tosyl-1,3,4,6,7,8-hexa-hydro-2H-pyrimido[1,2-a]pyrimidin-1-ium iodide.

Two compounds, (S)-8-{[(tert-butyl-dimethyl-sil-yl)-oxy]meth-yl}-1-[(2,2,4,6,7-penta-methyl-2,3-di-hydro-benzo-furan-5-yl)sulfon-yl]-1,3,4,6,7,8-hexa-hydro-2H-pyrimido[1,2-a]pyrimidin-1-ium tri-fluoro-methane-sulfonate, C27H46N3O4SSi+·CF3O3S-, (1) and (S)-8-(iodo-meth-yl)-1-tosyl-1,3,4,6,7,8-hexa-hydro-2H-pyrimido[1,2-a]pyrimidin-1-ium iodide, C15H21IN3O2S+·I-, (2), have been synthesized and characterized. They are bicyclic guanidinium salts and were synthesized from N-(tert-but-oxy-carbon-yl)-l-me-thio-nine (Boc-l-Met-OH). The guanidine is protected by a 2,2,4,6,7-penta-methyl-dihydro-benzo-furan-5-sulfonyl (Pbf, 1) or a tosyl (2) group. In the crystals of both compounds, the guanidinium group is almost planar and the N-H forms an intra-molecular hydrogen bond in a six-membered ring to the oxygen atom of the sulfonamide protecting group.

Measuring Pathological and Nonpathological Orthorexic Behavior: Validation of the Teruel Orthorexia Scale (TOS) among Polish Adults.

Measuring orthorexia nervosa is challenging due to the use of various existing tools and problems with sample representativeness. Another challenge for the Polish population is the adaptation of existing research tools and the evaluation of their relevance and research reliability. Our research aimed to adapt the TOS to the Polish language and measure pathological and nonpathological orthorexic behavior among the Polish population. The adaptation of the PL-TOS has high psychometric value and allows us to assess healthy and nervous orthorexia levels. This scale can be used not only for further research but also for diagnostic purposes in the daily work of clinicians and psychologists. Our results obtained in the present study indicate a correlation between TOS and both the use of supplements and diet. Higher TOS, ORTO_R and KZZJ_Diet Restrictions scores were obtained for individuals using dietary supplements than for those not using dietary supplements. In the future, it is worth conducting research aimed at various risk groups of individuals with orthorexia to confirm the psychometric properties of this adaptation of the TOS.

Crystal structure of 2-[(5-amino-1-tosyl-1H-pyrazol-3-yl)-oxy]-1-(4-meth-oxy-phen-yl)ethan-1-one 1,4-dioxane monosolvate.

In the structure of the title compound, C19H19N3O5S·C4H8O2, the two independent dioxane mol-ecules each display inversion symmetry. The pyrazole ring is approximately parallel to the aromatic ring of the oxy-ethanone group and approximately perpendicular to the tolyl ring of the sulfonyl substituent. An extensive system of classical and 'weak' hydrogen bonds connects the residues to form a layer structure parallel to (201), within which dimeric subunits are conspicuous; neighbouring layers are connected by classical hydrogen bonds to dioxanes and by 'weak' hydrogen bonds from Htol-yl donors.

Thoracic outlet syndrome caused by superior mediastinal mass: A case report.

INTRODUCTION: Thoracic outlet syndrome (TOS) caused by superior mediastinal soft tissue mass has never been reported in the literature, the aim of this study is to discuss a case of TOS caused by a superior mediastinal mass in which the histopathological examinations of the mass showed vascular malformation. CASE REPORT: A 45-year-old female presented with left upper limb pain and numbness for three months, associated with swelling and attacks of shortness of breath. Imaging studies showed soft tissue mass involving the superior mediastinum. The condition of the patient deteriorated and the signs and symptoms of TOS became clearer, all provocative tests and nerve conduction studies were positive. The patient underwent thoracic outlet decompression. The patient did not respond and the symptoms deteriorated further. After a multidisciplinary board discussion, the patient was prepared for median sternotomy under general anesthesia. A total resection of the mass was done. The patient was totally relieved a few hours after the operation. DISCUSSION: The etiology of TOS can be multifaceted. Several factors contribute to its onset, and these can be categorized as congenital or acquired. Congenital causes include anatomical anomalies such as a cervical rib, or an elongated transverse process of the cervical vertebrae. These anatomical deviations can reduce the size of the thoracic outlet and make it prone to compression. CONCLUSION: Although it is rare, TOS could be due to superior mediastinal mass and the treatment of choice is total resection either through median sternotomy or thoracoscopic procedure.

Minimally invasive resection of a prominent transverse process in neurogenic thoracic outlet syndrome: new application for a primarily spinal approach. Illustrative case.

BACKGROUND: The optimal surgical approach to treat neurogenic thoracic outlet syndrome (nTOS) depends on the individual patient's anatomy as well as the surgeon's experience. The authors present a minimally invasive posterior approach for the resection of a prominent transverse process to reduce local muscular trauma. OBSERVATIONS: A 19-year-old female presented with painful sensations in the right arm and severe fine-motor skill dysfunction in the right hand, each of which had been present for several years. Further examination confirmed affected C8 and T1 areas, and imaging showed an elongated C7 transverse process displacing the lower trunk of the brachial plexus. Decompression of the plexus structures by resection of the C7 transverse process was indicated, owing to persistent neurological effects. Surgery was performed using a minimally invasive posterior approach in which the nuchal soft tissue was bluntly dissected by dilatators and resection of the transverse process was done microscopically through a tubular retractor. The postoperative course showed a sufficient reduction of pain and paresthesia. LESSONS: The authors describe a minimally invasive posterior approach for the treatment of nTOS with the aim of providing indirect relief of strain on brachial plexus structures. The advantages of this technique include a small skin incision and minor soft tissue damage.

Cichorium intybus L. significantly alleviates cigarette smoke-induced acute lung injury by lowering NF-κB pathway activation and inflammatory mediators.

Background: Cigarette smoke (CS) is one of the primary causes of acute lung injury (ALI) via provoking pulmonary inflammation and oxidative stress. Despite substantial studies, no effective treatment for ALI is presently available. Purpose: New prospective treatment options for ALI are required. Thus, this project was designed to investigate the in vivo and in vitro protective effects of 70 % methanolic-aqueous crude extract of whole plant of Cichorium intybus (Ci.Mce) against CS-induced ALI. Study design: /methods: Initially, male Swiss albino mice were subjected to whole-body CS exposure for 10 continuous days to prepare CS-induced ALI models. Normal saline (10 mL/kg), Ci.Mce (100, 200, 300 mg/kg), and Dexamethasone (1 mg/kg) were orally administered to respective animal groups 1 h prior to CS-exposure. 24 hrs after the last CS-exposure, BALF and lungs were harvested to study the key characteristics of ALI. Next, HPLC analysis was done to explore the phytoconstituents. Results: Ci.Mce exhibited significant reductions in lung macrophage and neutrophil infiltration, lung weight coefficient, and albumin exudation. Additionally, it effectively ameliorated lung histopathological alterations and hypoxemia. Notably, Ci.Mce exerted inhibitory effects on the excessive generation of IL-6, IL-1ß, and KC in both CS-induced ALI murine models and CSE-stimulated RAW 264.7 macrophages. Noteworthy benefits included the attenuation of oxidative stress induced by CS, evidenced by decreased levels of MDA, TOS, and MPO, alongside enhanced TAC production. Furthermore, Ci.Mce demonstrated a marked reduction in CS-induced NF-κB expression, both in vivo and in vitro. Conclusion: Consequently, Cichorium intybus could be a therapeutic option for CS-induced ALI due to its ability to suppress inflammatory reactions, mitigate oxidative stress, and quell NF-κB p65 activation.

¿Se puede utilizar la determinación del pico flujo de tos para valorar la capacidad tusígena en enfermedades respiratorias obstructivas graves? / Can cough peak flow be used to assess cough capacity in severe obstructive respiratory diseases?

Introducción: La valoración de la capacidad tusígena se realiza con la medición del flujo espiratorio máximo durante la tos (peak-flow tos [PFT]). Sin embargo, esta valoración podría alterarse por enfermedades con obstrucción espiratoria de la vía aérea. El objetivo fue valorar la medición de la capacidad tusígena mediante PFT en pacientes con enfermedad pulmonar obstructiva crónica (EPOC), así como las correlaciones con la función pulmonar, muscular respiratoria y orofaríngea. Métodos: Se seleccionaron los pacientes con EPOC y con enfermedad neuromuscular, así como los sujetos sanos a los que se había realizado una medición de la fuerza de los músculos respiratorios de forma asistencial. De esta población, se analizaron los valores de la función respiratoria, así como la fuerza muscular orofaríngea. En un subgrupo de pacientes con EPOC se realizó el estudio de deglución por videofluoroscopia. Resultados: Se incluyeron 307 sujetos (59,3% EPOC, 38,4% enfermedades neuromusculares y 2,3% sanos). En el grupo EPOC, el PFT se encontraba disminuido de forma estadísticamente significativa comparado tanto con el grupo de los sanos como con los enfermos neuromusculares. El 70% de los EPOC tenían una disminución patológica del PFT. Solamente, existía una correlación directa entre el PFT con el grado de obstrucción bronquial y la fuerza de los músculos espiratorios. No se encontró alteración de la función de los músculos inspiratorios ni orofaríngeos. Conclusiones: La utilización del PFT en los pacientes con EPOC no refleja la capacidad tusígena ya que se ve influenciada por el grado de obstrucción bronquial. Por tanto, se deberían valorar nuevas pruebas diagnósticas para la medición de la capacidad tusígena, fundamentalmente, en los pacientes que coexistan enfermedades neuromusculares y patología obstructiva bronquial grave.(AU)

Introduction: Cough capacity is assessed by measuring cough peak flow (CPF). However, this assessment could be altered by obstructive airway diseases. The aim was to assess measurement of cough capacity by CPF in patients with chronic obstructive pulmonary disease (COPD), as well as correlations with pulmonary, respiratory muscle, and oropharyngeal function. Methods: Patients with COPD, and with neuromuscular disease, were selected as well as healthy subjects who had undergone respiratory muscle strength measurement in a healthcare setting. From this population, respiratory function values and lung and oropharyngeal muscle function were analysed. A subgroup of COPD patients underwent a videofluoroscopic swallow study. Results: Three hundred and seven subjects were included (59.3% COPD, 38.4% neuromuscular diseases, and 2.3% healthy). CPF was found to be statistically significantly decreased in the COPD group compared to both the healthy and neuromuscular disease groups. Of the COPD patients, 70% had a pathological decrease in CPF. There was only a direct correlation between CPF with the degree of bronchial obstruction and expiratory muscle strength. No alteration of inspiratory or oropharyngeal muscle function was found. Conclusions: The use of CPF in COPD patients does not reflect cough capacity as it is influenced by the degree of bronchial obstruction. Therefore, new diagnostic tests to measure cough capacity should be considered, especially in patients with coexisting neuromuscular diseases and severe bronchial obstructive disease.(AU)

Un paciente con... Tos / A patient with... Cough

El 3,3-10% de la población presenta tos crónica, siendo un motivo frecuente de consulta en Atención Primaria (AP). Se plantea el caso de una mujer de 61 años con tos de 3 meses de evolución. La sospecha diagnóstica es de fibrosis pulmonar en el contexto de una posible artritis reumatoide versus neumonía intersticial descamativa secundaria a aripiprazol. El caso clínico sirve de reflexión sobre la importancia de una buena anamnesis en AP, así como un correcto uso de las pruebas complementarias para valorar causas menos frecuentes de un síntoma común. Debe desarrollarse una capacidad inductiva y valorar el contexto del síntoma guía para confeccionar un diagnóstico sindrómico lo más acertado posible, lo cual es muy valioso en este nivel asistencial. (AU)

Chronic cough is a common reason for consultation in primary care (prevalence approximately 3.3% to 10.0%). We report a case of a 61-year-old woman with a three-month history of cough. The most accurate diagnosis is pulmonary fibrosis in the context of rheumatoid arthritis versus desquamative interstitial pneumonia secondary to aripiprazole. This case study serves as a reflection on the importance of a good history in primary care. Moreover, it is relevant to correctly use complementary tests. It is especially important to make a good syndromic diagnosis and evaluate the context of the patient in front of us. (AU)

Exploring the Feasibility of a Comprehensive Screening for Voice and Swallowing Function in Post-Extubation Patients: A Pilot Study

Objectives: This pilot study aimed to identify and test a battery of time-efficient and cost-effective voice and swallowing screening tools for post-extubated patients in Chile. Methods: A panel of four experts selected and rated voice and swallowing screening tools. Seven measures were selected: smoothed cepstral peak prominence (CPPS) and maximum phonation time (MPT) for voice assessment, Volume-Viscosity Swallow Test (V-VST) for swallowing, voluntary and reflex peak cough flow for cough assessment, Eating Assessment Tool-10 (EAT-10), and Vocal Symptom Scale (VoiSS) for patient-reported outcomes. These tools were applied to four post-extubation patients within 48-72 hours post-hospital discharge, alongside the assessment of 17 matched controls. Results: Post-extubation patients showed significantly shorter MPT, lower CPPS values, increased V-VST dysphagia signs, reduced voluntary peak cough flow, and more pronounced symptoms on both the VoiSS and EAT-10 compared to controls. Limitations: The study had a modest sample size and relied solely on clinical screening tools. Value: This pilot study suggests a feasible and cost-effective approach to voice and swallowing screening for post-extubation patients, valuable in resource-constrained settings. Conclusion: While these accessible tools are not gold-standard assessments, they offer valuable insights and can guide future research. This study underscores the potential of selected tools in facilitating early detection of voice and swallowing disorders in post-extubation patients.

Objetivos: Este estudio piloto tuvo como objetivo identificar y probar una batería de herramientas de detección de problemas de voz y deglución que fueran eficientes en cuanto a tiempo y costo para pacientes chilenos postextubados. Métodos: Un panel de cuatro expertos seleccionó y evaluó herramientas de detección de voz y deglución. Se seleccionaron siete medidas: prominencia de pico cepstral suavizado (CPPS) y tiempo máximo de fonación (TMF) para la evaluación de la voz, prueba de volumen-viscosidad (V-VST) para la deglución, flujo máximo voluntario y reflejo de la tos para evaluar la tos, Eating Assessment Tool-10 (EAT-10) y la Escala de Sintomas Vocales (ESV) para los resultados informados por los pacientes. Estas herramientas se aplicaron a cuatro pacientes postextubados (48-72 horas), junto con la evaluación de 17 controles pareados. Resultados: Los pacientes postextubados mostraron un TMF y CPPS significativamente más bajos, aumento de los indicios de disfagia en la V-VST, reducción del flujo máximo de la tos y síntomas más pronunciados tanto en la ESV como en la EAT-10 en comparación con los controles. Limitaciones: El estudio tuvo un tamaño de muestra reducida y se basó únicamente en herramientas de detección clínica. Valor: Este estudio piloto sugiere un enfoque factible y rentable para la detección de problemas de voz y deglución en pacientes postextubados, valioso en entornos con recursos limitados. Conclusión: Aunque ese abordaje no sustituye a las evaluaciones de referencia, ofrece información valiosa y puede guiar futuras investigaciones que busquen facilitar la detección temprana de los trastornos de la voz-deglución en pacientes postextubados.

Mecánica Tusígena / Cough Mechanics

El control neurológico de la tos o la neurofisiología de la tos, implica una serie de eventos complejos en el sistema nervioso que coordinan y desencadenan este reflejo protector pulmonar. Esta intrincada red de señales nerviosas y coordinación muscular se origina en los receptores de la tos, pasa por el centro de la tos en el bulbo raquídeo y finalmente activa los músculos necesarios para la adecuada eliminación del agente irritante. Este mecanismo involucra, la detección del estímulo por receptores especializados, transducción de señales que viajan a lo largo de fibras nerviosas aferentes hacia el sistema nervioso central, centro integrador a nivel del bulbo raquídeo, en el centro de la tos es donde se procesa las señales de los receptores y se coordina la respuesta. La integración de las señales y la respuesta radica en este centro de la tos y en la corteza cerebral quien regula y modula la tos. El control neuronal cortical de la tos implica la participación consciente y voluntaria de la corteza cerebral en la percepción, regulación y adaptación de la tos. La coordinación muscular requiere que la señal viaje por vías nerviosas eferentes motoras hacia los músculos involucrados, la contracción muscular se integra en una secuencia específica que desencadena las fases de la tos, inspiración máxima, compresión y expulsiva.

The neurological control of cough, or the neurophysiology of cough, involves a series of complex events in the nervous system that coordinate and trigger this lung protective reflex. This intricate network of nerve signals and muscle coordination originates from the cough receptors, passes through the cough center in the medulla oblongata, and finally activates the muscles necessary for proper elimination of the irritant. This mechanism involves the detection of the stimulus by specialized receptors, transduction of signals that travel along afferent nerve fibers towards the central nervous system, integrating center at the level of the medulla oblongata, in the cough center is where the signals are processed. receptors and the response is coordinated. The integration of signals and response resides in this cough center and in the cerebral cortex, which regulates and modulates coughing. Cortical neural control of cough involves the conscious and voluntary participation of the cerebral cortex in the perception, regulation, and adaptation of cough. Muscle coordination requires that the signal travel through efferent motor nerve pathways to the muscles involved; muscle contraction is integrated into a specific sequence that triggers the cough, maximum inspiration, compression, and expulsive phases.

B-mode transorbital ultrasonography for the diagnosis of idiopathic intracranial hypertension: an updated systematic review and meta-analysis.

OBJECTIVES: This systematic review and meta-analysis aimed to evaluate the role of B-mode transorbital ultrasonography (TOS) for the diagnosis of idiopathic intracranial hypertension (IIH) in adults. METHODS: MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials (CENTRAL) (1966-May 2022) were searched to identify studies reporting ultrasonographic data about the optic nerve sheath diameter (ONSD) and optic disc elevation (ODE) in adults with IIH compared to subjects without IIH. The quality of the included studies was evaluated by the Newcastle-Ottawa Quality. RESULTS: Fifteen studies were included (total of 439 patients). The values of ODE ranged from 0.6 to 1.3 mm in patients with IIH. The values of ONSD ranged from 4.7 to 6.8 mm in IIH patients and from 3.9 to 5.7 mm in controls. In IIH patients, the ONSD was significantly higher compared to controls (standardized mean difference: 2.5 mm, 95% confidence interval (CI): 1.6-3.4 mm). Nine studies provided data about the presence of papilledema and the pooled prevalence was 95% (95% CI, 92-97%). CONCLUSIONS: In adults, the thickness of ONSD and the entity of ODE were significantly associated with IIH. B-mode TOS enables to noninvasively detect increased ICP and should be performed, potentially routinely, in any patient with suspected IIH.

Effects of Quince Gel and Hesperidin Mixture on Experimental Endometriosis.

OBJECTIVES: Endometriosis (EM) is the presence of endometrial tissue outside the uterus. This study aimed to examine the effects of quince gel and hesperidin treatment on uterine tissue in an experimental endometriosis model. MATERIALS AND METHODS: Thirty-two rats were categorized into four groups as sham, EM, EM+quince gel (QG), and EM+QG+Hesperidin (HES). The endometriosis (EM) model was induced with surgical intervention. Estradiol benzoate (EB) was used to induce endometrial hyperplasia. In the EM group, EB was given to rats for 7 days. The EM+QG group received 2 cc QG for 21 days. HES treatment was given for 21 days after EM induction. At the end of the experiment, blood was taken from the animals and the serum total antioxidant status (TAS) and total oxidant status (TOS) values were studied. Uterine tissues were dissected and processed for histological paraffin embedding. Tissues were fixed in 4% glutaraldehyde solution and processed for ultrastructural analysis. RESULTS: After EM, QG and HES treatment significantly increased the TAS and decreased the TOS value. EM caused epithelial and glandular degeneration, thinning of the basal membranes, and vascular dilatation with increased fibrosis and edema. QG+HES restored the pathology and showed protective effects in uterine tissues. Caspase-3 expression was increased in the epithelium, glands, and muscle layers of the EM group. In EM+QG+HES, hesperidin protected cell survival and decreased Caspase-3 expression in uterine tissues. TNF-α expression was intense in inflammatory cells and the muscle layer in the EM group. HES reduced inflammation by decreasing the TNF-α expression. MAPK expression was increased after EM induction in epithelial, glandular, and inflammatory cells in the EM group. After HES treatment, MAPK expression was mainly negative in cells of uterine tissue in the EM+QG+HES group. Ultrastructurally, in the EM group, organelles were disrupted and dilated and degenerated after EM induction. QG and HES treatment improved cellular organelles. CONCLUSION: Local vaginal applications can be an alternative treatment method in the endometriosis model via QG+HES treatment promoting cell proliferation and angiogenesis and preventing cell death.

Introducción: En las enfermedades neuromusculares la disminución de la capacidad vital se relaciona con dismunición de la capacidad tusígena y luego ventilatoria, la combinación de ambas genera complicaciones graves por falla ventilatoria. En los pacientes que son intubados, limita la extubación, sino se realizan cuidados respiratorios especializados. El conocimiento y aplicación de los profesionales que atienden a estos pacientes en cuidados intensivos resulta esencial. Objetivos: Reportar el conocimiento y aplicación especializada de cuidados respiratorios en enfermedades neuromusculares en las Unidades de Cuidados Intensivos. Materiales y métodos: Estudio cualitativo, descriptivo de corte transversal, no probabilístico, a criterio. La población accesible fueron profesionales de la Salud de las Unidades de Cuidados Intensivos, y el análisis de las respuestas de una encuesta estructurada, enviada a distintos profesionales a nivel mundial. Resultados: Se incluyeron los cuestionarios de 41 profesionales, el 34% de los profesionales reportaron la utilización regular de Asistente Mecánico de la Tos; 22% refirieron la utilización regular de apilamiento de aire; 31% reportaron la utilización regular de Asistencia Ventilatoria No Invasiva, 56.1% de los profesionales afirmaron conocer la diferencia entre Ventilación No Invasiva y Soporte Ventilatorio No Invasivo, 34% de los profesionales refirieron tener formación especializada en el área. Conclusión: Pese a existir una alta proporción de profesionales con conocimiento especializado, un grupo importante no los aplica rutinariamente. La justificación es principalmente por la dificultad de adquisición y financiación de los equipos necesarios.

Introduction: In neuromuscular diseases, the decrease in vital capacity relates to decreased coughing and then ventilatory capacity, the combination of both generating serious complications due to ventilatory failure. In intubated patients, the extubation process is difficult unless specialized respiratory care is provided. The knowledge and treatment application of the professionals who care for these patients in intensive care is of outmost importance. Objectives: Report the knowledge and specialized application of respiratory care in neuromuscular diseases in Intensive Care Units. Materials and methods: Qualitative, descriptive, cross-sectional, non-probabilistic study, at criteria. The accessible population were Health professionals from the Intensive Care Units, and the analysis of the responses of a structured survey, sent to different professionals worldwide. Results: The questionnaires of 41 professionals were included, 34% of the professionals reported the regular use of the Mechanical Cough Assistant; 22% reported the regular use of air stacking; 31% reported the regular use of Non-Invasive Ventilatory Assistance. 56.1% of the professionals stated that they knew the difference between Non-Invasive Ventilation and Non-Invasive Ventilatory Support, 34% of the professionals reported having specialized training in the area. Conclusion: Despite the existence of a high proportion of professionals with specialized knowledge, an important group does not routinely apply them. The justification is mainly due to the difficulty of acquiring and financing the necessary equipment.

Arterial thoracic outlet syndrome by a commonly overlooked anomaly, the cervical rib: A case report.

Thoracic outlet syndrome (TOS) is a constellation of symptoms that occur due to the compression of neurovascular structures traversing the thoracic outlet. TOS manifests in 3 distinct forms: neurogenic, venous, and arterial. Among these, arterial TOS is the rarest. A 32-year-old man presenting with severe right arm pain was referred for CT angiography. The imaging revealed bilateral cervical ribs, with the right side showing more pronounced development and fusion with the first thoracic rib. At the fusion site of the right cervical rib and the first thoracic rib, a pseudoaneurysm of the right subclavian artery was detected. Additionally, there was evidence of acute thromboembolism in the right brachial artery at the mid-humerus. Arterial thoracic outlet syndrome is a rare form of TOS that can have detrimental consequences due to associated complications. Cross-sectional imaging, such as CT scans and MRI, is the preferred method for diagnosing TOS and identifying its specific form. Physicians are expected to be familiar with the various forms of TOS, the lesions mimicking TOS, and the imaging tools utilized for diagnosis.
