揂ir Bubble Sign� and Fibreoptic Bronchoscopy in Complicated Pulmonary Hydatid Cysts: Steps in the Right Direction

Intact pulmonary hydatid cysts are often discovered incidentally on chest X-rays (CXRs) as rounded opaque lesions with smooth borders. Cyst rupture and infection (complicated hydatid cyst) often change the radiologic appearance delaying diagnosis. Air bubble sign on computed tomography is recognized as a sign of high sensitivity and specificity in the diagnosis of complicated hydatid cysts when compared to other classical radiologic signs. Bronchoscopy is not a preferred investigation in patients with intact hydatid cysts but may have a major role in patients with complicated hydatid cysts with atypical presentation. In the present case series, we attempt to highlight the importance of the 揳ir bubble sign� and the identification of a whitish membrane at bronchoscopy in the diagnosis of complicated hydatid cysts.

Relación entre la ubicación de la burbuja de aire en la transferencia embrionaria y las tasas de implantación y gestación evolutiva / Relationship between air bubble location at embryo transfer and implantation and ongoing pregnancy rates

Resumen OBJETIVO: Evaluar la relación entre la ubicación de la burbuja de aire que contiene los embriones y las tasas de implantación y de gestación clínica. El secundario: estudiar la relación entre la posición de la punta de la cánula, el grosor endometrial y el desplazamiento de la burbuja con esos desenlaces reproductivos. MATERIALES Y MÉTODOS: Estudio retrospectivo, observacional y de análisis de imágenes ecográficas de transferencias de embrión único en estadio de blastocisto practicadas por un mismo especialista en la Fundación IVI, Valencia, España, entre septiembre de 2013 y febrero de 2021. Criterios de selección: grosor endometrial ≥ 6 mm en el último control ecográfico, ausencia de miomas, IMC menor de 30 kg/m2, transferencias atraumáticas efectuadas por el mismo especialista. En función de la ubicación de la burbuja de aire se establecieron tres grupos de estudio (alta: mayor de 0.98 cm, media: 0.98 a 1.44 cm y baja: mayor de 1.44 cm) y para evaluar la asociación entre las categorías se aplicó el cálculo de razón de momios (OR) e IC95%. RESULTADOS: Se estudiaron 342 transferencias de embrión único. La edad media de las pacientes fue 39.70 ± 4.5 años. La relación entre la distancia de la burbuja de aire al fondo uterino y la tasa de implantación fue de 61 ± 9% en el grupo de ubicación alta, 64 ± 9% en el grupo de ubicación media, y de 56 ± 1% en el grupo de ubicación baja (p = 0.437). No se observaron diferencias en la tasa de gestación evolutiva analizada mediante probabilidad de ocurrencia entre grupos, con frecuencias de 0.60 en comparación con 0.64 (OR: 1.42; IC95%: 0.83 a 2.44; p: 0.199) y en la ubicación alta con media, y frecuencias de 0.60 en comparación con 0.56 (OR: 1.22; IC95%: 0.72-2.08; p: 0.462) entre alta y baja. CONCLUSIONES: No se encontró asociación entre la ubicación de la burbuja y las tasas de implantación y de gestación evolutiva. El mayor desplazamiento de la burbuja se asoció con mayores tasas de gestación evolutiva.

Abstract OBJECTIVE: To evaluate the relationship between the location of the air bubble containing the embryos and the implantation and clinical gestation rates. Secondary: to study the relationship between the position of the cannula tip, the endometrial thickness and the displacement of the bubble with these reproductive outcomes. MATERIALS AND METHODS: Retrospective, observational, ultrasound image analysis study of single embryo transfers at blastocyst stage performed by the same specialist at the IVI Foundation, Valencia, Spain, between September 2013 and February 2021. Selection criteria: endometrial thickness ≥ 6 mm at the last ultrasound control, absence of fibroids, BMI less than 30 kg/m2, atraumatic transfers, performed by the same specialist. Based on the location of the air bubble, three study groups were established (high: greater than 0.98 cm, medium: 0.98 to 1.44 cm and low: greater than 1.44 cm) and the odds ratio (OR) and 95%CI were used to evaluate the association between the categories. RESULTS: A total of 342 single embryo transfers were studied. The mean age of the patients was 39.70 ± 4.5 years. The relationship between the distance of the air bubble to the uterine fundus and the implantation rate was 61 ± 9% in the high placement group, 64 ± 9% in the medium placement group, and 56 ± 1% in the low placement group (p = 0.437). No differences were observed in the evolutionary gestation rate analyzed by probability of occurrence between groups, with frequencies of 0.60 compared to 0.64 (OR: 1.42; 95%CI: 0.83 to 2.44; p: 0.199) and high to medium location, and frequencies of 0.60 compared to 0.56 (OR: 1.22; 95%CI: 0.72-2.08; p: 0.462) between high and low. CONCLUSIONS: No association was found between the air bubble localization and implantation or ongoing pregnancy rates. However, a greater displacement of the bubble was associated with higher ongoing pregnancy rates.

Thromboembolic Events Associated with Electrolytic Detachment of Guglielmi Detachable Coils and Target Coils : Comparison with Use of Diffusion-Weighted MR Imaging

OBJECTIVE: The purpose of this study was to retrospectively evaluate and compare the incidence of diffusion-weighted image (DWI) lesions between the Guglielmi detachable coil (GDC) and the Target coil for treating unruptured intracranial aneurysm. METHODS: From 2010 to 2011, consecutive 222 patients with an intracranial aneurysm underwent coil embolization. Inclusion criterias were : 1) unruptured intracranial aneurysm, 2) one or more GDC or Target coils used with or without other coils, 3) DWI examination within 24 hours after coiling, and 4) coiling performed without a balloon or stent. RESULTS: Ninety patients (92 cases) met the inclusion criteria. DWI lesions were detected in 55 (61.1%) of 90 patients. In the GDC group (n=44), DWI lesions were detected in 31 (70.5%). The average number of DWI lesions was 5.0+/-8.7 (mean+/-SD; range, 1-40) in aneurysm-related territory. In the Target coil group (n=48), DWI lesions were detected in 24 (50.0%). The number of DWI lesion was 2.1+/-5.4 (range, 1-32) in aneurysm-related territory. There was no significant correlation between a number of coils and DWI lesions. No significant differences were also observed in the number of DWI lesions in each group. CONCLUSION: The GDC and Target coils, which have an electrolytic detachable system, showed no differences in the incidence of DWI lesion.

In Vitro Observation of Air Bubbles during Delivery of Various Detachable Aneurysm Embolization Coils

OBJECTIVE: Device- or technique-related air embolism is a drawback of various neuro-endovascular procedures. Detachable aneurysm embolization coils can be sources of such air bubbles. We therefore assessed the formation of air bubbles during in vitro delivery of various detachable coils. MATERIALS AND METHODS: A closed circuit simulating a typical endovascular coiling procedure was primed with saline solution degassed by a sonification device. Thirty commercially available detachable coils (7 Axium, 4 GDCs, 5 MicroPlex, 7 Target, and 7 Trufill coils) were tested by using the standard coil flushing and delivery techniques suggested by each manufacturer. The emergence of any air bubbles was monitored with a digital microscope and the images were captured to measure total volumes of air bubbles during coil insertion and detachment and after coil pusher removal. RESULTS: Air bubbles were seen during insertion or removal of 23 of 30 coils (76.7%), with volumes ranging from 0 to 23.42 mm3 (median: 0.16 mm3). Air bubbles were observed most frequently after removal of the coil pusher. Significantly larger amounts of air bubbles were observed in Target coils. CONCLUSION: Variable volumes of air bubbles are observed while delivering detachable embolization coils, particularly after removal of the coil pusher and especially with Target coils.

Balanced Salt Solution Contained within Plastic Bag and the one Encased within Bottle

PURPOSE: Air bubbles developed during phcoemulsification procedure are known to be harmful to corneal endothelial cells and balanced salt solution(BSS) contained within plastic bag(Bag BSS) has been thought to be more prone to the air bubble formation than the one encased within bottle(Bottle BSS). For the above reason, we tried to see whether there is any difference in corneal endothelial cell changes between two groups of patients who underwent phacoemulsification using Bag BSS and Bottle BSS respectively. METHODS: 85 cataract eyes of 60 patients were randomly assigned to two groups of Bag BSS(43 eyes) and Bottle BSS(42 eyes), on which phacoemulsification was performed through scleral tunnel incision followed by silicone PCL placement. Corneal endothelial cells were examined using specular microscopy postoperatively at 1 month and compared with preoperative specular microscopic data. RESULTS: The percent loss of corneal endothelial cell density at postoperative 1 month for the Bag BSS group(13.02+/-0.7%) was not significantly different from the Bottle BSS group(12.8+/-8.1%)(p>0.05). Coeffcient of variation in cell size(p>0.05) and mean endothelial cell size(p>0.05) also showed no significant difference between the two groups. CONCLUSION: In conclusion, Bag BSS and Bottle BSS have similiar protective effect on the corneal endothelial cell damage during phocoemulsification.

Effects of Air Bubble on the Corneal Endothelium

During intraocular surgery including cataract, air bubbles occasionally enter the anterior chamber during irrigation. The influences of these air bubbles on the cornea endothelium, however, have yet to be known. The purpose of this study is to investigate the effects of bubbles on the rabbit corneal endothelium during irrigation and aspiration mode in experimental phacoemulsification. After anesthesia, the anterior chamber was irrigated and aspirated for 1 minute with balanced salt solution. The rabbits were then randomly divided into 4 groups. In group 1, corneal endothelial irrigation and aspiration were performed without air bubbles for 1 minute. In group 2, corneal endothelial irrigation was performed in the presence of air bubbles in the anterior chamber for 1 minute. In group 3, corneal endothelial irrigation and aspiration were performed in the presence of air bubbles in the anterior chamber for 1minute. In group 4, corneal endothelial irrigation was performed with silicone oil at 50 mmHg pressure in the presence of air bubbles in the anterior chamber for 1 minute. In group 1, the cornea endothelial cells showed normal F-actin without cell damage. In group 2, a ring shaped endothelial cell destruction area adjacent to the border was found along the margin of the air bubble. In group 3, similar ring-shaped lesion found in group 2 were observed but with more extensive cell destruction. In group 4, a partial number of cell to cell separation was found without endothelial cell destruction. In conclusion, air bubbles in the anterior chamber during irrigation with balanced salt solution showed destructive changes in rabbit corneal endothelial cell.
