Monitorización avanzada durante la desvinculación de la ventilación mecánica invasiva en el trasplante unipulmonar / Advanced monitoring during weaning of invasive me chanical ventilation in single-lung transplantation

Resumen El trasplante de pulmón bilateral es el tratamiento de las enfermedades pulmonares en su etapa terminal. Sin embargo, a veces se realiza el trasplante de un solo pulmón. La técnica no está exenta de complicaciones como la hiperinsuflación aguda del pulmón nativo y cambios en el diafragma, predisponiendo a atelectasias e insuficiencia respiratoria que pueden derivar en resul tados negativos. Por lo tanto, las pruebas de respiración espontánea pueden fallar y retrasar el proceso de des vinculación de la ventilación mecánica. La combinación de herramientas de monitorización avanzadas, como la tomografía por impedancia eléctrica y la ecografía, para diagnosticar la causa de este fallo, reconociendo y cuantificando la distribución del volumen pulmonar y su comportamiento dinámico, podría ser crucial para mejorar los resultados. Presentamos el caso de un paciente con trasplante unipulmonar y ventilación prolongada que falla en repetidas ocasiones durante la desvinculación de la ventilación mecánica, donde utilizamos herramientas de monitoreo avanzado para detectar la causa de la falla.

Abstract Bilateral lung transplantation is the treatment of end-stage lung diseases. However, sometimes a single lung transplant is performed. The technique is not exempt from complications such as acute hyperinfla tion of the native lung and changes in the diaphragm, predisposing to atelectasis and respiratory failure that can lead to negative results. Therefore, spontaneous breathing trials may fail and delay the weaning process. The combination of advanced monitoring tools, such as electrical impedance tomography and ultrasonography, to diagnose the cause of this failure, recognizing and quantifying the distribution of lung volume and its dynamic behavior could be crucial to improve outcomes. We present the case of a patient with a one-lung transplant and prolonged mechanical ventilation who, after presenting successive failures in the weaning pro cess, underwent advanced monitoring in order to find the causes of the failure.

Application of real-time virtual sonography surgical navigation combined with indocyanine green fluorescence imaging technology during anatomical liver resection / 中华肝胆外科杂志

Objective:To analyze the clinical effect of real-time virtual sonography (RVS) surgical navigation combined with indocyanine green fluorescence imaging technology in the anatomical liver segmentectomy for hepatocellular carcinoma (HCC).Methods:The clinical data of 35 patients who underwent anatomical liver segmentectomy using RVS surgical navigation combined with indocyanine green fluorescence imaging technology in the Department of Hepatobiliary Surgery of Peking University International Hospital from January 2020 to January 2022 were retrospectively analyzed. There were 22 males and 13 females, aged (60.0±10.0) years. RVS is real-time virtual sonography, which fuses real-time intraoperative ultrasound images with corresponding preoperative CT or MRI images to guide the surgical plane. Methods of operation, time of operation, intraoperative blood loss, operative margin, hospital stay and postoperative complications were analyzed. Postoperative complications were graded by Clavien-Dindo system. The 1-year overall survival and tumor-free survival rates of patients were followed up by outpatient or telephone review.Results:Anatomical liver segmentectomy was performed on 36 patients, including 1 patient (2.9%) of segment Ⅱ, 1 patient (2.9%) of segment Ⅲ, 5 patients (14.3%) of segment Ⅳ, 6 patients (17.1%) of segment Ⅴ, 10 patients (28.6%) of segment Ⅵ, 7 patients (20.0%) of segment Ⅶ, 4 patients (11.4%) of segment Ⅷ, and 1 patient (2.9%) of segments Ⅴ+ Ⅷ. The operation time of 35 patients was (310.2±81.6) min, with an intraoperative blood loss of [ M( Q1, Q3)] 390.0(250.0, 500.0) ml. The hospital stay was (11.6±2.1) d. There was no postoperative death. Postoperative complications occurred in 3 cases (8.6%), of which 2 cases (5.7%) were ascites, Clavien-Dindo grade Ⅰ; Postoperative hemorrhage occurred in 1 case (2.9%), Clavien-Dindo grade Ⅱ. HCC was confirmed by pathology in all cases, and the operative margins were negative. The median follow-up time was 14 months (12 to 20 months). The 1-year overall survival rate after surgery was 100.0%(35/35), three patients (8.6%) had tumor recurrence, and the 1-year tumor-free survival rate was 91.4% (32/35). Conclusion:RVS surgical navigation combined with indocyanine green fluorescence imaging technology could be feasible in anatomical segmental hepatectomy for HCC.

Is Portable Cardiopulmonary Ultrasound the Future of Heart Failure Diagnosis?

Aim of the Study: Heart failure is a major problem of public health in Morroco , pulmonary congestion is a key sign which can be easly detected by pulmonary sonography via interlobular septal thickening. The aim of this study was to establish a link Between kerley B lines in the lung and signs of pulmonary congestion. In addition to assess the evolution of these parameters in response to diuretic treatment. Materials and Methods: We prospectively evaluate 118 patients who presented to the emergency of IBN Rochd Hospital in Casablanca with sensation of breathlessness at baseline, 7 days, one month and 3 months for kerley B lines, NYHA Class of dyspnea and the levels of NT pro bnp. the duration of this study was 4 months. Results: Kerley B lines were present in 87.4% of patients initially, 67.6% had elevated levels of NT-probnp and 53%,30%,16% had dyspnea Class II, III and IV respectively. Diuretic treatment have shown a similar improvement of kerley B lines, levels of NT pro bnp and the class of dyspnea . In deed after a follow up of 3 month : only 7 % of patients had persistant kerley b lines, NT pro bnp levels were high in only 7.6% these findings were concordant with the clinical symptomatolgy. Hence only 7% of our patients suffered from dyspnea at moderate efforts at the end of the study. Conclusion: We demonstrated in this study a positive correlation between kerley b lines and levels of NT pro-bnp. These findings may facilitate the orientation of patients within the emergency department and help to initiate heart failure treatment rapidely.

Comparison of Mammography, Sonography, Fine-Needle Aspiration Cytology, and Excision Biopsy for the Diagnosis of Breast Lesions

Background and Objective: Problem of invasive tests in breast lesion diagnosis can be addressed by comparing noninvasive tests with final Histopathological diagnosis obtained a?er excision biopsy. Present study was carried out to study diagnos?c u?lity of mammography, sonography, FNAC compared to excision biopsy for diagnosis of breast lesions Methods: Prospec?ve Observa?onal study was carried out among 81 women with Breast related symptoms. Digital Mammography Machine, ACUSON S3000TM Ultrasound System; FNAC and surgery for excision Biopsy were used. Sensi?vity, Specificity, Accuracy, Posi?ve and Nega?ve Predic?ve values were measured and p<0.05 was considered as sta?s?cally significant. Results: Sonography and FNAC composite have sensi?vity, specificity, accuracy, posi?ve and nega?ve predic?ve values 100.00%, 81.40%, 90.12%, 82.61% and 100.00% respec?vely. Mammography+FNAC (97.3%) is not as sensi?ve as Sonography+FNAC (100%), Sonography combined with FNAC is equally sensi?ve to excision biopsy (100%) and therefore can be used for screening purpose. Conclusion: Contrary to present guidelines which consider Mammography as most important screening tool for Breast Cancer, combina?on of Sonography and FNAC can be considered equally reliable.

Diagnostic Hysteroscopy and Saline Infusion Sonography in Abnormal Uterine Bleeding

One of the commonest reasons for women seeking gynecological advice is Abnormal uterine bleeding (AUB). Most common anatomical causes of abnormal uterine bleeding in women are endometrial polyps, sub mucosal fibroids and endometrial hyperplasia. Hysteroscopy is an effective procedure but is more expensive than Saline Infusion Sonography (SIS). Direct visualization of uterine cavity is possible by hysteroscopy, but it does not give any information about myometrium and adnexa. Saline infusion sonography is effortlessly accepted by most patients as it can be an outpatient procedure. This article present summary of salient features of the procedure which will help the practitioner to take informed decision.

Power Doppler sonography – A supplement to hysteroscopy in abnormal uterine bleeding: Redefining diagnostic strategies

Background: Abnormal Uterine Bleeding (AUB) is a very frequent cause of gynecological visits in women of all age groups. Ultrasound pelvis with or without endometrial sampling have been conventionally used to make diagnosis. Power Doppler is a comparatively recent modality which can be used to screen patients who will need endometrial biopsy/ curretage. We hereby conducted a study to compare the diagnostic accuracy of power Doppler sonography and hysteroscopy with histopathology associated with abnormal uterine bleeding. We also calculated the incidence of uterine pathology in AUB by power Doppler ultrasound and hysteroscopy and compared it with histopathology. Methods: This prospective cohort study was conducted at the Department of Obstetrics and Gynaecology, Institute of Medical Sciences, Banaras Hindu University. After excluding 42 women, a total of 100 women fulfilling the inclusion criteria contributed to our study. Selected women underwent power Doppler ultrasound and hysteroscopy with guided biopsy. Results were compared with histopathology as per the gold standard. Evaluation of sensitivity, specificity, positive and negative predictive values were performed for each modality. All statistical analyses were performed using the SPSS 11.0 statistical package. P value ?0.05 was considered statistically significant for all tests used. Results: Sensitivity and specificity of power Doppler are 75% and 100% for carcinoma endometrium, 72.72% and 98.9% for endometrial hyperplasia, and 81.81% and 100% for endometrial polyp, respectively. Conclusion: Power Doppler sonography can be used to screen outpatients who do not need an endometrial biopsy for abnormal uterine bleeding. This will avoid unnecessary hysteroscopy in definitive benign cases, and watchful hysteroscopy in suspected premalignant and malignant cases. Irregular branching vessels and color splashes were found to be the best parameters for diagnosing endometrial carcinoma. Power Doppler should be done along with transvaginal sonography in all cases of abnormal uterine bleeding

Hysteroscopic Evaluation Of Abnormal Uterine Bleeding In A Tertiary Care Institute — An Observational Study

Objectives:To assess the feasibility of diagnos?c hysteroscopy in the diagnosis of abnormal structure and pathological lesions in the uterine cavi?es of women presen?ng abnormal bleeding of the uterus. Methods: This is a Prospec?ve Cross-sec?onal study conducted in the Department of Gynaecology at Prathima Ins?tute Of Medical Sciences, Karimnagar: one hundred women presen?ng with Abnormal Uterine Bleeding, over a period of one year from December 2020 to November 2021, were subjected to the procedure. Results: The results of our study show that hysteroscopy has high accuracy for detec?ng the pathology in women with abnormal uterine bleeding, especially in benign lesions such as endometrial polyp and submucosal fibroid and it can be used as the first line diagnos?c method for these abnormali?es. Conclusion:Hysteroscopy provides a more accurate diagnosis than dilata?on and cure?age or ultrasonography alone to diagnose pathology in women with abnormal bleeding of the uterus. It is very sensi?ve for diagnosing intracavitary lesions like submucous myoma and endometrial polyp

Sonographic features of pelvic pain among adults in a Nigerian population

Background:Pelvic pain is abdominal pain located below the level of umbilicus, including frequent lower back pain with or without radiation to the thighs. The aim of this study was to evaluate the common ultrasound findings in subjects with pelvic pain. Methods:Itwas a retrospective study and involved collection of information from the folders of the subjects. A total of 820 folders were used for this study. Information collected from these folders included; the age, sex, provisional diagnosis and ultrasound findings. Data collected was arranged and statistical package for social sciences (SPSS) version 20 was used for analysis. Descriptive statistics was used and results arranged in frequency tables and percentages. Results:The result showed that males were 160 (20%) and females were 660 (80%). The age ranged from < 20years to 70 years and above. The mean age of the subjects was 35.66�.82 years. The mean age of the male is 51.83�.56 years and that of the females is 31.77�.02 years. Normal scan was the predominant ultrasound finding. The most common pathological finding was uterine fibroid (21.3%) and followed by pelvic inflammatory disease (15.2%).Conclusions:Ultrasound is an essential tool in the diagnosis of pelvic pain in males and females. Uterine fibroid was the most common pathological finding in females while benign prostate hypertrophy was the most common in males.

Normative references of fetal chest circumference in a Nigerian population

A linear relationship between gestational age and fetal thoracic size has been observed, with growth occurring at a regular rate from 16 to 40 weeks.Objective: To determine the fetal chest circumference in normal late second and third-trimester pregnancies in a Nigerian population.Materials and Methods: This was a descriptive cross-sectional study carried out on gravid women with normal singleton pregnancies at 22 ­ 38 weeks gestational age. We recruited 440 eligible gravid women. The fetal gestational age was estimated from the last menstrual period and an early first trimester ultrasound report (< 10 weeks). The fetal chest circumference was measured on an axial view of the fetal chest after ensuring adequate visualisation of the four cardiac chambers, both fetal lungs and ribs. The other fetal biometric parameters were determined using the previously established guidelines. Descriptive statistics, Pearson's correlation, and regression analysis were used as appropriate. Statistical tests were considered significant at P ≤ 0.05.Results: The mean age of the subjects was 29.8 ± 4.6 years (range = 18-45 years). The chest circumference of the fetuses ranged from 16.56 ± 0.29 cm to 30.87 ± 6.88 cm. The fetal chest circumferences increased with advancing gestational age (16.56 ± 0.29 cm at 22 weeks to 30.87 ± 6.88 cm at 37 weeks gestational age). There was strong positive correlation between chest circumference and menstrual gestational age (r=0.85, p=<0.0001), biparietal diameter (r=0.88, p<0.0001), abdominal circumference (r=0.90, p<0.0001) and fetal length (r=0.88, p<0.0001).Conclusion: The fetal chest circumference grew as the pregnancy progressed. There was a positive linear correlation between fetal chest circumference and menstrual gestational age as well as the other fetal biometric parameters.

Accuracy of sonographic identification of suprascapular nerve at supraclavicular fossa: a cadaveric study / Precisión de la identificación ecográfica del nervio supraescapular en la fosa supraclavicular: un estudio cadavérico

SUMMARY: Sonographic identification of suprascapular nerve (SSN) is essential for diagnosis of suprascapular neuropathy and ultrasound-guided suprascapular nerve block. This study aims to demonstrate the accuracy of identification of SSN at supraclavicular region by ultrasonography in fresh cadavers. Ninety-three posterior cervical triangles were examined. With ultrasonography, SSN emerging from the upper trunk of brachial plexus was identified and followed until it passed underneath the inferior belly of omohyoid muscle. Sonographic visualization of SSN in supraclavicular fossa was recorded. Then, cadaveric dissection was performed to determine the presence or absence of SSN. An agreement between sonographic identification and direct visualization was specified and categorized the following three patterns: "correctly identified" (pattern I), "incorrectly identified" (pattern II), and "unidentified" (pattern III). The identification of SSN using sonography was correct in almost 90 %. The diameter of SSN with pattern I was the largest compared to those of other two patterns. In pattern I, SSN ran laterally from the upper trunk of brachial plexus and passed underneath the inferior belly of omohyoid muscle. Therefore, SSN was easily identified under ultrasonography. In pattern II, nerve identified by ultrasonography was literally the dorsal scapular nerve. In pattern III, SSN was unable to be identified because of its anatomical variation. The accuracy of ultrasonographic identification of SSN at supraclavicular fossa is high and the key sonoanatomical landmarks are the lateral margin of brachial plexus and the inferior belly of omohyoid muscle. The anatomical variants of SSN are reasons of incorrect or unable identification of SSN under ultrasonography.

RESUMEN: La identificación ecográfica del nervio supraescapular (NSE) es esencial para el diagnóstico de neuropatía supraescapular y bloqueo del nervio supraescapular mediante la ecografía. Este estudio tiene como objetivo demostrar la precisión de la identificación de NSE en la región supraclavicular por ecografía en cadáveres frescos. Se examinaron noventa y tres triángulos cervicales posteriores. Se identificó el NSE emergente de la parte superior del tronco del plexo braquial con la ecografía, y se siguió hasta su trayecto por debajo del vientre inferior del músculo omohioideo. Se registró la visualización ecográfica del NSE en la fosa supraclavicular. Luego, se realizó disección cadavérica para determinar la presencia o ausencia de NSE. Se especificó un acuerdo entre la identificación ecográfica y la visualización directa y se categorizaron los siguientes tres patrones: "identificado correctamente" (patrón I), "identificado incorrectamente" (patrón II) y "no identificado" (patrón III). La identificación de NSE mediante ecografía fue correcta en casi el 90 %. El diámetro del NSE con el patrón I fue el más grande en comparación con los de los otros dos patrones. En el patrón I, NSE corría lateralmente desde la parte superior del tronco del plexo braquial y pasaba por debajo del vientre inferior del músculo omohioideo. Por lo tanto, el NSE se identificó fácilmente mediante ecografía. En el patrón II, el nervio identificado por ecografía era literalmente el nervio escapular dorsal; en el patrón III, el NSE no pudo ser identificado debido a su variación anatómica. La precisión de la identificación ecográfica del NSE en la fosa supraclavicular es alta y los puntos de referencia sonoanatómicos clave son el borde lateral del plexo braquial y el vientre inferior del músculo omohioideo. Las variantes anatómicas de NSE son razones de identificación incorrecta o incapaz de NSE bajo ecografía.

Conclusions: Extended thoracic ultrasound showed that, in the hands of general surgeons, it is a reliable, safe, noninvasive, inexpensive and repeatable tool that allows rapid diagnosis and treatment of thoracic injuries(AU)

Displasia del desarrollo de la cadera: tamizaje y manejo en el lactante / Developmental dysplasia of the hip: screening and management in the infant

La displasia del desarrollo de la cadera comprende un conjunto de anormalidades que afectan la articulación coxofemoral: la displasia, subluxación y luxación de la cadera. El concepto de "displasia" describe anormalidades en la estructura femoral, acetabular o ambas. Corresponde a la patología ortopédica más frecuente del recién nacido y lactante, lo que genera mucha preocupación e intranquilidad entre los padres, en los primeros controles sanos de sus hijos. Es una patología en la que un diagnóstico oportuno y precoz son la clave para poder realizar un tratamiento efectivo, obteniendo como resultado una cadera clínica y radiológicamente normal al finalizar el desarrollo esquelético. Para esto es fundamental conocer la patología e ir activamente en su búsqueda. Actualmente existe mucha discusión sobre la manera de pesquisar esta patología. En Chile, se realiza tamizaje universal con imagen -radiografía de pelvis- a todos los niños a los 3 meses de edad. El objetivo de la siguiente revisión, es traer a la práctica clínica actual de todos aquellos profesionales que se enfrentan en distintos escenarios a esta patología: médicos de atención primaria, enfermeras, médicos en etapas de destinación y formación en distintas regiones del país, pediatras y ortopedistas, aquellas características y signos de sospecha propios de esta enfermedad y detallar las herramientas para un correcto diagnóstico y oportuno tratamiento.

Developmental dysplasia of the hip (DDH) comprises a set of abnormalities that affect the hip joint: hip dysplasia, subluxation, and dislocation. It is the most frequent orthopedic pathology of the newborn and infant, and it generates great concern among parents during the first health check-ups of their children. It is a condition in which a timely and early diagnosis is key to be able to carry out an effective treatment, obtaining as a result of a clinically and radiologically normal hip at the end of skeletal development. For this, it is essential to know this orthopedic condition and actively search for it. Currently, there is much discussion about how to screen DDH. In Chile, universal screening with imaging - pelvic radiography - is performed on all children at 3 months of age. The objective of the following review is to bring to the current clinical practice of all those professionals who face this pathology in different scenarios: primary care physicians, nurses, physicians in training stages in different regions of the country, pediatricians and orthopedic surgeons, signs of suspicion typical of the disease and detail the assessment tools for a correct diagnosis and timely treatment.

Damage control surgery for thoracic outlet vascular injuries: the new resuscitative median sternotomy plus REBOA / Cirugía de control de daños para lesiones del opérculo torácico: nuevo abordaje mediante esternotomía mediana y REBOA

Abstract Thoracic vascular trauma is associated with high mortality and is the second most common cause of death in patients with trauma following head injuries. Less than 25% of patients with a thoracic vascular injury arrive alive to the hospital and more than 50% die within the first 24 hours. Thoracic trauma with the involvement of the great vessels is a surgical challenge due to the complex and restricted anatomy of these structures and its association with adjacent organ damage. This article aims to delineate the experience obtained in the surgical management of thoracic vascular injuries via the creation of a practical algorithm that includes basic principles of damage control surgery. We have been able to show that the early application of a resuscitative median sternotomy together with a zone 1 resuscitative endovascular balloon occlusion of the aorta (REBOA) in hemodynamically unstable patients with thoracic outlet vascular injuries improves survival by providing rapid stabilization of central aortic pressure and serving as a bridge to hemorrhage control. Damage control surgery principles should also be implemented when indicated, followed by definitive repair once the correction of the lethal diamond has been achieved. To this end, we have developed a six-step management algorithm that illustrates the surgical care of patients with thoracic outlet vascular injuries according to the American Association of the Surgery of Trauma (AAST) classification.

Resumen El trauma vascular torácico está asociado con una alta mortalidad y es la segunda causa más común de muerte en pacientes con trauma después del trauma craneoencefálico. Se estima que menos del 25% de los pacientes con una lesión vascular torácica alcanzan a llegar con vida para recibir atención hospitalaria y más del 50% fallecen en las primeras 24 horas. El trauma torácico penetrante con compromiso de los grandes vasos es un problema quirúrgico dado a su severidad y la asociación con lesiones a órganos adyacentes. El objetivo de este artículo es presentar la experiencia en el manejo quirúrgico de las lesiones del opérculo torácico con la creación de un algoritmo de manejo quirúrgico en seis pasos prácticos de seguir basados en la clasificación de la AAST. que incluye los principios básicos del control de daños. La esternotomía mediana de resucitación junto con la colocación de un balón de resucitación de oclusión aortica (Resuscitative Endovascular Balloon Occlusion of the Aorta - REBOA) en zona 1 permiten un control primario de la hemorragia y mejoran la sobrevida de los pacientes con trauma del opérculo torácico e inestabilidad hemodinámica.

Damage control in the emergency department, a bridge to life / Control de daños en la sala de emergencias: un puente hacia la vida

Abstract Patients with hemodynamic instability have a sustained systolic blood pressure less or equal to 90 mmHg, a heart rate greater or equal to 120 beats per minute and an acute compromise of the ventilation/oxygenation ratio and/or an altered state of consciousness upon admission. These patients have higher mortality rates due to massive hemorrhage, airway injury and/or impaired ventilation. Damage control resuscitation is a systematic approach that aims to limit physiologic deterioration through strategies that address the physiologic debt of trauma. This article aims to describe the experience earned by the Trauma and Emergency Surgery Group (CTE) of Cali, Colombia in the management of the severely injured trauma patient in the emergency department following the basic principles of damage control surgery. Since bleeding is the main cause of death, the management of the severely injured trauma patient in the emergency department requires a multidisciplinary team that performs damage control maneuvers aimed at rapidly controlling bleeding, hemostatic resuscitation, and/or prompt transfer to the operating room, if required.

Resumen Un paciente politraumatizado hemodinámicamente inestable es aquel que ingresa al servicio de urgencias con una presión arterial sistólica menor o igual de 90 mmHg, una frecuencia cardiaca mayor o igual a 120 latidos por minuto y un compromiso agudo de la relación ventilación/oxigenación y/o del estado de conciencia. Por esta razón, existe una alta mortalidad dentro de las primeras horas de un trauma severo ya sea por una hemorragia masiva, una lesión de la vía aérea y/o una alteración de la ventilación. Siendo el objetivo de este artículo describir el manejo en urgencias del paciente politraumatizado hemodinámicamente inestable de acuerdo con los principios de control de daños. El manejo del paciente politraumatizado es una estrategia dinámica de alto impacto que requiere de un equipo multidisciplinario de experiencia. El cual debe de evolucionar conjunto a las nuevas herramientas de diagnóstico y tratamiento endovascular que buscan ser un puente para lograr una menor repercusión hemodinámica en el paciente y una más rápida y efectiva estabilización con mayores tasas de sobrevida.

Damage control surgery for splenic trauma: "preserve an organ - preserve a life" / Control de daños en trauma esplénico: "preserva un órgano, preserva la vida"

Abstract The spleen is one of the most commonly injured solid organs of the abdominal cavity and an early diagnosis can reduce the associated mortality. Over the past couple of decades, management of splenic injuries has evolved to a prefered non-operative approach even in severely injured cases. However, the optimal surgical management of splenic trauma in severely injured patients remains controversial. This article aims to present an algorithm for the management of splenic trauma in severely injured patients, that includes basic principles of damage control surgery and is based on the experience obtained by the Trauma and Emergency Surgery Group (CTE) of Cali, Colombia. The choice between a conservative or a surgical approach depends on the hemodynamic status of the patient. In hemodynamically stable patients, a computed tomography angiogram should be performed to determine if non-operative management is feasible and if angioembolization is required. While hemodynamically unstable patients should be transferred immediately to the operating room for damage control surgery, which includes splenic packing and placement of a negative pressure dressing, followed by angiography with embolization of any ongoing arterial bleeding. It is our recommendation that both damage control principles and emerging endovascular technologies should be applied to achieve splenic salvage when possible. However, if surgical bleeding persists a splenectomy may be required as a definitive lifesaving maneuver.

Resumen El bazo es uno de los órganos sólidos comprometidos con mayor frecuencia en el trauma abdominal y el diagnóstico oportuno disminuye la mortalidad. El manejo del trauma esplénico ha cambiado considerablemente en las últimas décadas y hoy en día se prefiere un abordaje conservador incluso en casos de lesión severa. Sin embargo, la estrategia óptima para el manejo del trauma esplénico en el paciente severamente traumatizado aún es controvertida. El objetivo de este artículo es proponer una estrategia de manejo para el trauma esplénico en pacientes politraumatizados que incluye los principios de la cirugía de control de daños en base a la experiencia obtenida por el grupo de Cirugía de Trauma y Emergencias (CTE) de Cali, Colombia. La decisión entre un abordaje conservador o quirúrgico depende del estado hemodinámico del paciente. En pacientes hemodinámicamente estables, se debe realizar una tomografía axial computarizada con contraste endovenoso para determinar si es posible un manejo conservador y si requiere angio-embolización. Mientras que los pacientes hemodinámicamente inestables deben ser trasladados inmediatamente al quirófano para empaquetamiento esplénico y colocación de un sistema de presión negativa, seguido de angiografía con embolización de cualquier sangrado arterial persistente. Es nuestra recomendación aplicar conjuntamente los principios del control de daños y las tecnologías endovasculares emergentes para lograr la conservación del bazo, cuando sea posible. Sin embargo, si el sangrado persiste puede requerirse una esplenectomía como medida definitiva para salvaguardar la vida del paciente.

Abdominal ultrasound augments the medical students' ability to identify free intraabdominal fluid

SUMMARY OBJECTIVE: Free intra-abdominal fluid describes an accumulation of free fluid in the peritoneal cavity. It has different etiologies, but it frequently constitutes a meaningful clinical sign. In this study, the authors interrogate whether abdominal ultrasound augments the medical students' ability to identify free intra-abdominal fluid. METHODS: Thirty-one medical students without any previous formal ultrasound training were subjected to cognitive assessment before and after four and a half-hour of theoretical lecture and hands-on course about the diagnosis of free intra-abdominal fluid by physical examination and abdominal ultrasound. The hands-on sessions were done in healthy volunteers with a simulated peritoneal catheter and in patients treated with peritoneal dialysis with different amounts of dialysate in their cavity. RESULTS: The cognitive assessment before and after the course increased from 6.7±2.3 to 11.6±1.1 points (p<0.0001). The sensitivity, specificity, and accuracy in the diagnosis of free intra-abdominal fluid were higher when students used abdominal ultrasound. The students agree with the inclusion of abdominal ultrasound in the diagnose of free intra-abdominal fluid in the undergraduate curriculum. CONCLUSIONS: This study demonstrates that incorporating abdominal ultrasound is feasible and improves medical students' short-time competency in performing and interpreting the findings diagnostic of free intra-abdominal fluid.

Objective:To measure the parameters of median nerve under ultrasound in patients with diabetes mellitus to explore the relationship between ultrasonic parameters and nerve conduction study. Methods:From June to November, 2019, 79 diabetic patients were divided into diabetic peripheral neuropathy (DPN) group (n = 37) and non-DPN group (n = 42) according to the diagnosis. Their right median nerve were measured cross-sectional area (CSA) and the proportion of hypoechoic areas (HA) 5 cm and 10 cm proximal to the wrist (CSA-5, CSA-10, HA-5 and HA-10, respectively) with sonography; while the conductive latency and velocity of right median nerves were measured with nerve conductive study. Results:CSA-5, CSA-10 and HA-10 were more in DPN group than in non-DPN group (|Z| > 2.282, P < 0.05). HA-5 correlated with the motor conductive latency (r = 0.264, P < 0.05) and velocity (r = -0.270, P < 0.05); HA-10 correlated with the abnormal sensory conductive latency (r = 0.234, P < 0.05) and velocity (r = 0.363, P < 0.01), and the motor conductive latency (r = 0.235, P < 0.05) and velocity (r = -0.255, P < 0.05). Conclusion:DPN can be found under sonography, some of them are related with the nerve electrophysiology, which may be a useful tool to screen DPN.

Efficacy of Fluid Administration Followed by Lung Sonography in Hemodynamic Assessment in Acute Circulatory Failure in Critically Ill Patients

Background:Early recognition and appropriate treatment of shock have been shown to decrease mortality. Incorporation of bedside ultrasound in patients with undifferentiated shock allows for rapid evaluation ofreversible causes of shock and improves accurate diagnosis in undifferentiated hypotension. The aim of the present study was to evaluate efficacy of fluid administration followed by lung sonography in hemodynamic assessment in acute circulatory failure in critically ill patients.Materials and Methods: This prospective cohort controlled randomized study was carried out on 50 Critically ill Patients who had acute circulatory failure in intensive care unit Tanta university hospital Critically ill patients of either sex aged 21-60 years when mean blood pressure was below 65 mmHg were included. Patients have been uniformly distributed in2 categories, The patients assigned either to the Control Group (group I) or to the FALLS (fluid administration limited by lung sonography) protocol group (group II)Results:Comparison between two groups revealed that, the heart rate showed that heart rate is lower in group II in comparison to group I .Comparison between two groups revealed that, the mean arterial blood pressure changes showed that it is higher in group II in comparison to group I .Comparison between two groups revealed that, the Central venous pressure showed that no significant difference in the base line .Intensive care unit stay in group I rangedbetween 5 –11 days while in group II ranged between 3 –8 days .Survival analysis (Kaplan Mier curve), Mortality at 28 days found in group I mean 21.28 days with SE 1.898 and in group II mean 24 days with SE 1.64 with no significant difference in time but there was significant difference in number of mortalities as discussed before.Conclusion:We conclude from this study that bedside Lung Ultrasound has a good accuracy and superiority in assessment over other traditionally used methods for detecting early signs of pulmonary congestion and thus guides the fluid administration in shock management to decrease complications, mortality and intensive care stay

Evaluation of endometrial causes of postmenopausal bleeding with it's correlation with endometrial thickness and hysteroscopy findings and endometrial tissue histopathology

Background: Postmenopausal bleeding (PMB)accounts for 5% of gynecology visit. All with unexpected uterine bleeding should be evaluated for endometrial carcinoma since this potentially lethal disease is the cause of bleeding in approximately 10 percent patients (range 1 to 25 percent, depending upon risk factors). The aim of the study was to evaluate endometrial causes of postmenopausal bleeding (PMB) with it's correlation with endometrial thickness (ET)and hysteroscopy findings and endometrial tissue histopathology.Methods: A total 50 consecutive cases of PMB fulfilling the inclusion and exclusion criteria and giving informed consent were selected. Each patient was subjected to transvaginal sonography (TVS) in which uterus, adnexa and endometrial thickness (ET) was assessed. Then hysteroscopy and/or dilation and curettage was scheduled at subsequent visit. Endometrial sample was sent for histopathological examination. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and diagnostic accuracy was calculated for ET by TVS and hysteroscopy findings, considering histopathological diagnosis as the gold standard.Results: Most common endometrial cause of PMB was atrophic endometrium (44%). The other causes were endometrial carcinoma (18%), endometrial hyperplasia (18%), endometrial polyp (12%), endometritis (4%), and leiomyoma (4%). The diagnostic accuracy of ET by TVS at a cut-off point of 5 mm was 94% with sensitivity 89.3%, specificity 100%, PPV 100% and NPV 88%. The diagnostic accuracy of hysteroscopy was 98% with sensitivity 96.4%, specificity 100%, PPV 100% and NPV 95.7%.Conclusions: Being relatively cheap, easily accessible, non-invasive, TVS with ET measurement should first line investigation in the evaluation of women with postmenopausal bleeding with suspected endometrial pathology. Although hysteroscopy is more specific and sensitive, in poor resource settings it should be limited to cases with ill-defined endometrial lining, recurrent/ persistent bleeding and cases with endometrial thickness greater than 5 mm irrespective of endometrial echotexture.
