RESUMO

Introduction The presence of foreign bodies in the airways remain a diagnostic challenge to healthcare professionals. They can become life threatening emergencies that require immediate intervention or go unnoticed for weeks and even months. Prevention is best but early recognition remains a critical factor in treatment of foreign body inhalation in children. Objective To study the diagnostic advantages of virtual over rigid bronchoscopy in the evaluation of children with suspected foreign body in the tracheobronchial tree and plan for early management. Methods A crossectional study conducted at a tertiary care hospital & medical college in India. A total 24 patients (0-12-years-old) who presented with complaints of sudden onset of coughing, choking, and breathing difficulty were included during the 2-year duration, from January 2018 to December 2019. All patients underwent virtual and rigid bronchoscopy. Results In 8 patients, foreign bodies detected by virtual bronchoscopy were confirmed by rigid bronchoscopy. There was one case in which virtual bronchoscopy showed no foreign body, but rigid bronchoscopy detected it. In 15 cases virtual and rigid bronchoscopy did not show foreign bodies. The sensitivity, specificity, positive and negative predictive value of virtual bronchoscopy were 88.88, 100, 100, and 93.75%, respectively. Conclusions Virtual bronchoscopy is less invasive and does not require general anesthesia but cost and availability are limitations. It can be used as method of investigation in children with suspected foreign body aspiration.

RESUMO

Introduction: In-situ right atrial (RA) thrombus is a rare occurrence typically associated with heightened inflammatory or hypercoagulable states. Here, we present a case of in-situ RA thrombus mimicking atrial myxoma in a patient with sepsis and bacteraemia. Case description: A 41-year-old man presented with septic arthritis and bacteraemia caused by methicillin-resistant Staphylococcus aureus (MRSA). A transoesophageal echocardiogram revealed a large pediculated mass resembling atrial myxoma, which was not visible on transthoracic echocardiography performed four days earlier. Cardiac magnetic resonance (CMR) imaging strongly suggested a thrombus, leading to the patient undergoing transcatheter aspiration. Subsequent pathology confirmed an organised fibrin thrombus without evidence of infection. Discussion: The patient's in-situ RA thrombus likely developed in response to a heightened inflammatory state associated with sepsis. Limited data exist on in-situ RA thrombi in the absence of atrial fibrillation, though some reports suggest a correlation between heightened inflammation and a hypercoagulable state. Conclusion: CMR imaging is invaluable for characterising such masses and can aid in distinguishing a thrombus from a myxoma. LEARNING POINTS: Differentiating right atrial (RA) thrombus from myxoma: cardiac magnetic resonance imaging is essential for distinguishing RA thrombus from myxoma, preventing unnecessary surgeries.Hypercoagulable and inflammatory states: spontaneous in-situ RA thrombi can occur without deep vein thrombosis (DVT) or atrial fibrillation, especially in hypercoagulable and inflammatory conditions.Transcatheter aspiration: this less invasive alternative to surgery is effective for large, mobile RA thrombi, reducing embolisation risk.

RESUMO

Aspiration detected in the fiberoptic endoscopy evaluation of swallowing (FEES) has been inconsistently associated with pneumonia, with no evidence of the risk of pneumonia from other alterations in swallowing safety detected in FEES. We conducted a dynamic, ambidirectional cohort study involving 148 subjects at risk of dysphagia in a tertiary university hospital. Our aim was to determine the risk of pneumonia attributed to alterations in swallowing safety detected during FEES. We used multivariate negative binomial regression models to adjust for potential confounders. The incidence density rate (IR) of pneumonia in patients with tracheal aspiration of any consistency was 26.6/100 people-years (RR 7.25; 95% CI: 3.50-14.98; P < 0.001). The IR was 19.7/100 people-years (RR 7.85; 95% CI: 3.34-18.47; P < 0.001) in those with laryngeal penetration of any consistency and 18.1/100 people-years (RR 6.24; 95% CI: 2.58-15.09; P < 0.001) in those with pharyngeal residue of any consistency. When adjusted for aspiration, the association of residue and penetration with pneumonia disappeared, suggesting that their risk of pneumonia is dependent on the presence of aspiration and that only aspiration is independently associated with pneumonia. This increased risk of pneumonia was significant in uni- and multivariate negative binomial regression models. We found an independently increased risk of pneumonia among patients with dysphagia and aspiration detected during FEES. Alterations in the oral and pharyngeal phases of swallowing, without aspiration, did not increase the risk of pneumonia.

RESUMO

OBJECTIVE: The study aimed to assess the predictive significance of inflammatory parameters as potential markers for malignancy in individuals with thyroid nodules. METHOD: Nine hundred and ninety-one patients with thyroid nodules who had undergone thyroid fine-needle aspiration biopsy were included and classified according to the Bethesda system. Neutrophil lymphocyte ratio (NLR) and systemic immune-inflammation index (SII) values obtained from hemogram parameters were determined for each patient. The study examined the correlation between the Bethesda classification and NLR/SII levels. In addition, a comparison was made between the inflammatory parameters of the benign and malignant Bethesda groups. RESULTS: Five hundred and seventy-three patients were classified as Bethesda 2 (benign), 34 as Bethesda 6 (malignant). A correlation was observed between the Bethesda classification and NLR and SII levels (r: 0.230, p < 0.001; r: 0.207 p < 0.001, respectively). NLR and SII values were significantly higher in the malignant group (p < 0.001). The cutoff value for SII in predicting benign and malignant thyroid nodules was 489.86 × 103/mm3 with a sensitivity of 88.2% and a specificity of 63.7%. The cutoff value for NLR for the same prediction was 2.06 with a sensitivity of 82.4% and a specificity of 83.4%. CONCLUSIONS: The findings of this study indicate that SII and NLR may be valuable prognostic markers for predicting the malignancy of thyroid nodules.


OBJETIVO: Evaluar parámetros inflamatorios como posibles marcadores de malignidad en individuos con nódulos tiroideos. MÉTODO: Se incluyeron 991 pacientes con nódulos tiroideos que se sometieron a biopsia por aspiración con aguja fina y se clasificaron según el sistema de Bethesda. Se determinaron los valores de la relación neutrófilo-linfocito (NLR) y el índice de inflamación inmunitaria sistémica (SII). El estudio exploró la correlación entre la clasificación de Bethesda y los valores de NLR/SII, y comparó los parámetros inflamatorios de los grupos benignos y malignos de Bethesda. RESULTADOS: Se clasificaron 573 pacientes como Bethesda 2 (benigno) y 34 como Bethesda 6 (maligno). Se observó una correlación entre la clasificación de Bethesda y los valores de NLR y SII (r: 0.230; r: 0.207). Los valores de NLR y SII fueron mayores en el grupo maligno (p < 0.001). El valor de corte para SII en la predicción de nódulos tiroideos benignos y malignos fue de 489.86 × 103/mm3, con una sensibilidad del 88.2% y una especificidad del 63.7%; para NLR fue de 2.06, con una sensibilidad del 82.4% y una especificidad del 83.4%. CONCLUSIONES: El SII y el NLR pueden ser valiosos marcadores pronósticos para predecir la malignidad de los nódulos tiroideos.

RESUMO

BACKGROUND: Among other structures, nuclear grooves are vastly found in papillary thyroid carcinoma (PTC). Considering that the application of artificial intelligence in thyroid cytology has potential for diagnostic routine, our goal was to develop a new supervised convolutional neural network capable of identifying nuclear grooves in Diff-Quik stained whole-slide images (WSI) obtained from thyroid fineneedle aspiration. METHODS: We selected 22 Diff-Quik stained cytological slides with cytological diagnosis of PTC and concordant histological diagnosis. Each of the slides was scanned, forming a WSI. Images that contained the region of interest were obtained, followed by pre-formatting, annotation of the nuclear grooves and data augmentation techniques. The final dataset was divided into training and validation groups in a 7:3 ratio. RESULTS: This is the first artificial intelligence model based on object detection applied to nuclear structures in thyroid cytopathology. A total of 7,255 images were obtained from 22 WSI, totaling 7,242 annotated nuclear grooves. The best model was obtained after it was submitted 15 times with the train dataset (14th epoch), with 67% true positives, 49.8% for sensitivity and 43.1% for predictive positive value. CONCLUSIONS: The model was able to develop a structure predictor rule, indicating that the application of an artificial intelligence model based on object detection in the identification of nuclear grooves is feasible. Associated with a reduction in interobserver variability and in time per slide, this demonstrates that nuclear evaluation constitutes one of the possibilities for refining the diagnosis through computational models.

RESUMO

Introduction Laryngomalacia is the most common congenital laryngeal alteration, with spontaneous resolution in most cases. However, in the face of more severe presentations of the disease, it is necessary to perform supraglottoplasty surgery. Studies have been dedicated to researching changes in swallowing in children with laryngomalacia before and after surgical intervention. Objectives To identify the prevalence of oropharyngeal dysphagia in children with pre and postsupraglottoplasty laryngomalacia. Data Synthesis A search strategy was developed with terms and entreterms to designate a population pediatric with laryngomalacia , exposure supraglottoplasty , and outcome frequency of dysphagia , adapted to the requirements of the main databases in the health area. The analysis of the records found was performed by two independent examiners and, in the end, 6 articles were included in the study. The articles found enabled a sample of 330 children with laryngomalacia, 311 of whom underwent supraglottoplasty. Among the included studies, 5 were grouped and meta-analyzed. After supraglottoplasty surgery, a 59% reduction in the prevalence of oropharyngeal dysphagia was identified, with high heterogeneity I 2 = 93%. Conclusion Despite the heterogeneity of the sample, the supraglottoplasty procedure significantly reduces the prevalence of dysphagia in children with laryngomalacia.

RESUMO

Background and study aims There are rare data on the usefulness of endosonography-guided tissue acquisition (EUS-TA) in patients with pancreatic cystic lesions (PCLs). This study aimed to determine the accuracy of EUS-TA with ProCore 20G (PC20) for differentiating between mucinous neoplasia (MN) and non-MNs (n-MN) and identifying malignant PCLs, as well as its adverse events (AEs) in patients with PCLs without a classificatory diagnosis by imaging exams. Patients and methods In this observational, retrospective, single-center study, all patients with PCL who underwent EUS-TA due to diagnostic doubts in imaging studies were consecutively recruited from June 2017 to December 2021. The outcomes were to determine the diagnostic accuracy of EUS-TA with PC20 for differentiating between MN and n-MN, identifying malignant PCLs, and the AEs. Results Herein, 145 patients underwent EUS-TA, with 83 women (57.2%) and a mean age of 62.2 years. The mean size was 2.3 cm, with 81 patients (77.9%) having a PCL < 3.0 cm. The final diagnosis was made by EUS-TA (n = 81), surgery (n = 58), and follow-up (n = 6). The sensitivity, specificity, positive and negative predictive values, and accuracy for differentiating between MNs and n-MNs and identifying malignant PCLs were 92.6%, 98.4%, 98.7%, 91.3%, and 95.2% (kappa=0.9), and 92%, 99.2%, 95.8%, 98.3%, and 97.9% (kappa = 0.93), respectively. The AE rate was 2.7%, with no deaths in this cohort. Conclusions EUS-TA with PC20 has high accuracy and technical success with a low AE rate for PCL diagnosis.

RESUMO

BACKGROUND: Cerebral Venous Sinus Thrombosis (CVST) is a rare but potentially life-threatening condition, often associated with specific risk factors. The primary treatment for CVST is anticoagulation, but some cases progress to Refractory CVST (rCVST), requiring endovascular treatment. A combination of stent retriever and catheter aspiration is emerging as a promising technique to enhance treatment effectiveness. We conducted a systematic review and meta-analysis to assess the safety and efficacy of this approach, aiming to improve recanalization success and neurological outcomes while reducing complications in rCVST patients. METHODS: A search following PRISMA guidelines was conducted across Pubmed, Embase, Web of Science, and Cochrane databases to identify studies on the use of stent retrievers and catheter aspiration for rCVST. Pooled analysis with 95 % confidence intervals was used to assess the effects. Heterogeneity was evaluated using I2 statistics and a random-effects model was used. Complete recanalization. good clinical outcomes (mRS ≤ 2), hemorrhagic, neurological, ischemic, and total complications, poor clinical outcomes (mRS > 2), and mortality were assessed. RESULTS: A meta-analysis of five retrospective studies involving 55 patients examined outcomes in CVST. The median mean age was 40 years. Complete recanalization rate: 36 % (95 % CI: 9 % to 62 %, I2 = 90 %). Good clinical outcomes: 72 % (95 % CI: 50 % to 94 %, I2 = 76 %). Hemorrhagic complications: 2 % (95 % CI: 0 % to 8 %, I2 = 15 %). Ischemic complications: 0 % (95 % CI: 0 % to 6 %, I2 = 0 %). Neurological complications: 7 % (95 % CI: 0 % to 14 %, I2 = 0 %). Poor clinical outcomes: 26 % (95 % CI: 6 % to 46 %, I2 = 70 %). Total complications: 6 % (95 % CI: 0 % to 15 %, I2 = 10 %). Mortality rate: 5 % (95 % CI: 0 % to 13 %, I2 = 19 %). CONCLUSION: This systematic review and meta-analysis scrutinized the efficacy of combining Stent Retriever and Catheter Aspiration for rCVST. Findings highlighted varied outcomes, including recanalization rates, complications, and mortality. The dichotomy between good and poor outcomes underscores the necessity for personalized therapeutic decisions. While offering a comprehensive overview, the study emphasizes literature heterogeneity, suggesting a need for more rigorous and standardized research to optimize therapeutic strategies in clinical practice.

RESUMO

OBJECTIVE: To analyze if partial premature ovulation (PPO) detection during oocyte pick-up (OPU) impairs the quality of the retrieved oocyte cohort. METHODS: The PPO concept refers to the situation when premature ovulation happens only in some of the follicles and it is detected during OPU. This study constitutes a retrospective analysis performed in an infertility clinic (Spain) during 2016-2021 with patients undergoing OPU after controlled ovarian hyperstimulation for an in vitro fertilization (IVF) treatment. Study code: 2110-VLC-091- VG, registered on December 9 2021. Data from women with PPO (n=111) were compared to a matched control sample of cycles without PPO (n=333) at a proportion of 1:3. RESULTS: Cycles were matched for age, body mass index (BMI), treatment year, embryo genetic analysis and stimulation protocol type. The mean numbers of oocytes (6.1 vs. 11.2), mature oocytes (4.7 vs. 8.8), correctly fertilized oocytes (3.6 vs. 6.6) and top-quality blastocysts (0.9 vs. 1.8) were significantly lower in the PPO group than the nonPPO group (p<0.05). However, maturation, fertilization, top-quality blastocyst and pregnancy rates were statistically comparable among groups (p>0.05). CONCLUSIONS: Cycles with PPO have fewer available oocytes and, thus, fewer available embryos for transfer, al though their quality is intact, and still offer chances of pregnancy in these cases. Hence cycle cancellation may not be worth associated money, time and morale losses once PPO is detected.
