RESUMEN
Introduction: We retrospectively reviewed a case of a 42-year-old woman with intravenous leiomyomatosis. Clinical findings: The present study describes a case of IVL extending into the right internal and common iliac veins. Diagnosis: The patient was diagnosed by definitive pathological examination after a hysterectomy and double salpingectomy. Hypovolaemic shock due to delayed intraperitoneal bleeding from the ovarian vessels pedicle was observed. An emergent laparotomy for haemostasis was performed. A follow-up MRI, 2 months later, showed a polylobulated mass extending inside the right internal and common iliac veins. Intervention and result: The patient underwent a third laparotomic procedure with the removal of the right pelvic mass together with the involved veins. The postoperative course was uneventful, and the patient remains well at 3-month follow-up, with no signs of lower limb edema or venous disorders. Conclusion: Intracardiac leiomyomatosis is mostly diagnosed in premenopausal women. The most severe manifestation could be a vascular thrombosis or a right atrial tumor in the case of intracardiac involvement. Early and appropriate diagnosis is essential for optimal treatment. Surgery is the best treatment.(AU)
Introducción: Presentamos el caso de una paciente de 42 años con leiomiomatosis intravenosa. Hallazgos clínicos: El estudio presente describe un caso de IVL con afectación de las venas ilíaca común e interna derecha. Diagnóstico: La paciente fue diagnosticada mediante el examen histológico definitivo tras una histerectomía total con doble salpingectomía. Se objetivó un shock hipovolémico por sangrado intraperitoneal tardío del pedículo de vasos ováricos. Se realizó una laparotomía urgente para hemostasia. Una RMN durante el seguimiento, 2 meses después, mostró una masa polilobulada con afectación de la vena ilíaca común y la vena ilíaca interna derecha. Intervención y resultado: A la paciente se le realizó una tercera laparotomía con la extirpación de la masa pélvica derecha. El curso postoperatorio fue satisfactorio y la paciente permaneció asintomática a los 3 meses de seguimiento, sin signos de edema en extremidades inferiores ni otras afectaciones vasculares. Conclusión. La leiomiomatosis intracardíaca se diagnostica más frecuentemente en mujeres premenopáusicas. La forma de manifestación más severa sería una trombosis vascular o un tumor intracardíaco en la aurícula derecha, en el caso de afectación intracardíaca. Un diagnóstico precoz es esencial para un tratamiento óptimo. La cirugía es el mejor tratamiento.(AU)

Analysis of urine samples from COVID-19 patients by 1H NMR reveals important metabolic alterations due to SAR-CoV-2 infection. Previous studies have identified biomarkers in urine that reflect metabolic alterations in COVID-19 patients. We have used 1H NMR to better define these metabolic alterations since this technique allows us to obtain a broad profile of the metabolites present in urine. This technique offers the advantage that sample preparation is very simple and gives us very complete information on the metabolites present. To detect these alterations, we have compared urine samples from COVID-19 patients (n = 35) with healthy people (n = 18). We used unsupervised (Robust PCA) and supervised (PLS-LDA) multivariate analysis methods to evaluate the differences between the two groups: COVID-19 and healthy controls. The differences focus on a group of metabolites related to energy metabolism (glucose, ketone bodies, glycine, creatinine, and citrate) and other processes related to bacterial flora (TMAO and formic acid) and detoxification (hippuric acid). The alterations in the urinary metabolome shown in this work indicate that SARS-CoV-2 causes a metabolic change from a normal situation of glucose consumption towards a gluconeogenic situation and possible insulin resistance.

IntroductionHeavy menstrual bleeding is the major complaint in women with symptomatic fibroids. Ulipristal acetate (UPA) is a selective progesterone receptor modulator in which mixed agonist and antagonist activity appears to offer a novel approach to medical management of symptomatic uterine fibroids. There are currently no studies that have assessed its effect on the mammary gland in humans.MethodsProspective observational study conducted in a tertiary hospital, in which 14 consecutive patients diagnosed with uterine fibroids by transvaginal ultrasound were included. The patients received two cycles of UPA 5mg/day for 3 months each, with a rest period of two months between both cycles. To assess the safety on the mammary gland, 3 mammary ultrasounds were performed at three different points: prior to the first cycle of UPA, between the two cycles and at the end of the second cycle.ResultsOf the 14 recruited patients, 9 completed the study period. Breast ultrasound reports were normal in all patients. In 4 patients (44.4%), the 3 breast ultrasounds were classified as BI-RADS 2. In 2 patients (22.2%) the 3 breast ultrasounds were classified as BI_RADS1; and in 3 patients (33.3%), the first breast ultrasound was classified as BI-RADS 3 and the last two as BI-RADS 2.ConclusionIn conclusion, our study showed that 2 cycles of treatment with UPA in patients with symptomatic uterine fibroids is safe for normal breast tissue with an acceptable adverse effects profile. Nonetheless, further research is required to confirm our findings.
IntroducciónEl sangrado menstrual abundante es el principal síntoma en mujeres con miomas uterinos. Acetato de ulipristal (AUP) es un «modulador selectivo del receptor de progesterona» que parece ofrecer una nueva opción al manejo médico de los miomas debido a su acción mixta agonista y antagonista. Actualmente no hay estudios que evalúen su efecto en la glándula mamaria en humanos.MétodosEs un estudio prospectivo observacional realizado en un hospital terciario, en el cual se incluyeron 14 mujeres con diagnóstico de miomas uterinos mediante ecografía transvaginal. Las pacientes recibieron 2 ciclos de AUP 5mg/día durante 3 meses cada ciclo, con un período de descanso de 2 meses entre ambos ciclos. Para evaluar el impacto en la glándula mamaria se realizaron 3 ecografías mamarias en 3 momentos diferentes: previo al inicio del primer ciclo, entre los 2 ciclos y al terminar el segundo ciclo.ResultadosDe las 14 pacientes reclutadas, 9 completaron el período de estudio. Las ecografías mamarias en todas las pacientes fueron normales. En 4 pacientes (44,4%), las 3 ecografías mamarias fueron catalogadas como BI-RADS® 2. En 2 pacientes (22,2%) las 3 ecografías fueron catalogadas como BI-RADS® 1, y en 3 pacientes (33,3%), la primera ecografía mamaria fue catalogada como BI-RADS® 3 y las 2 últimas BI-RADS® 2.ConclusiónEn conclusión, nuestro estudio muestra que 2 ciclos de tratamiento con AUP en pacientes con miomas uterinos sintomáticos es seguro para el tejido mamario sano con efectos adversos aceptables. Sin embargo, hacen falta más estudios para confirmar nuestros resultados.

OBJECTIVE: To evaluate if the intraoperative human papillomavirus (IOP-HPV) test has the same prognostic value as the HPV test performed at 6 months after treatment of high-grade squamous intraepithelial lesion (HSIL) to predict treatment failure. DESIGN: Prospective cohort study. SETTING: Barcelona, Spain. POPULATION: A cohort of 216 women diagnosed with HSIL and treated with loop electrosurgical excision procedure (LEEP). METHODS: After LEEP, an HPV test was performed using the Hybrid Capture 2 system. If this was positive, genotyping was performed with the CLART HPV2 technique. The IOP-HPV test was compared with HPV test at 6 months and with surgical margins. MAIN OUTCOME MEASURE: Treatment failure. RESULTS: Recurrence rate of HSIL was 6%. There was a strong association between a positive IOP-HPV test, a positive 6-month HPV test, positive HPV 16 genotype, positive surgical margins and HSIL recurrence. Sensitivity, specificity, and positive and negative predictive values of the IOP-HPV test were 85.7, 80.8,24.0 and 98.8% and of the HPV test at 6 months were 76.9, 75.8, 17.2 and 98.0%. CONCLUSION: Intraoperative HPV test accurately predicts treatment failure in women with cervical intraepithelial neoplasia grade 2/3. This new approach may allow early identification of patients with recurrent disease, which will not delay the treatment. Genotyping could be useful in detecting high-risk patients. TWEETABLE ABSTRACT: IOP-HPV test accurately predicts treatment failure in women with CIN 2/3.

OBJECTIVE: Heart transplantation (HT) due to valvular cardiomyopathy is rare, namely, about 3% of cases in the Registry of the International Society for Heart and Lung Transplantation (ISHLT). Usually, these patients present some risk factors such as previous valvular operations and pulmonary hypertension. Since there are few studies in the literature, we retrospectively analyzed our early and long-term results. MATERIALS AND METHODS: We studied our experience in 22 HT cases for valvular cardiomyopathy (9.3% of our total experience), namely, 12 men and 10 women, of overall mean age of 52.6 +/- 10 years. Five patients had mitral; 8, aortic; and 1, tricuspid valve disease; 7 had double valve disease and 1, triple valve disease. Nineteen patients (87%) had been operated previously between 1 and 4 times. The mean ejection fraction was 23% +/- 7.3% and the mean New York Heart Association (NYHA) functional class was 3.7. Fifty-three percent of the patients had pulmonary hypertension. Two patients were operated as an emergency "O." We used the standard HT technique. RESULTS: Four patients (18%) were reoperated due to hemorrhage. The hospital mortality was 2 cases (9%). Another patients (9%) died on follow-up due to cardiac allograft vasculopathy. All surviving patients have been followed to the end of 2006. The mean follow-up has been 72 +/- 53 months. They are functional class I or II. CONCLUSIONS: HT for this indication was more frequent in our experience than in the Registry of the ISHLT. The immediate and long-term results were good, with an 82% mean survival at 6 years. HT can be a good treatment for patients with valvular cardiomyopathy and bad ventricular function and/or multiple valvular reoperations.

Sternal infection is a rare complication of median sternotomy but is associated with considerable morbidity and mortality, particularly in the case of deep sternal infection (mediastinitis). Successful treatment depends on early diagnosis and on the location (deep or superficial) of the infection. Radiological techniques have many limitations, and although 67Ga scintigraphy is effective, it delays diagnosis by 48 h. We assessed the diagnostic capacity of planar scintigraphy and single photon emission computed tomography (SPECT) with 99mTc-hexamethylpropylene amine oxime (HMPAO)-labelled leukocytes in deep sternal infections after median sternotomy. We prospectively studied 41 patients with clinical suspicion of deep sternal infection 4 and 20 h after administration of the tracer. The final diagnosis was deep sternal infection in nine patients and superficial sternal infection in 10, with infection being ruled out in 22 patients. Planar scintigraphy did not detect any of the deep sternal infections at either 4 h or 20 h. SPECT correctly identified eight of the nine deep sternal infections at 4 h and all seven at 20 h, with no false positive results. Planar scintigraphy identified 16 of the 18 superficial sternal infections at 4 h and all of them at 20 h. SPECT identified 17 of these 18 infections at 4 h and all of them at 20 h. Other infections unrelated to the sternotomy were identified in seven patients. Leukocytes labelled with 99mTc-HMPAO are a highly reliable method for the early diagnosis of sternal infections after median sternotomy. Use of SPECT allows determination of the depth of the infection and differentiation of superficial from deep sternal infections. It is also possible to detect other sites of infection, thus providing alternative diagnoses.

The aim of this study was to determine the normal planar and SPET patterns of the thoracic distribution of 99Tcm-hexamethylpropylene amine oxime (99Tcm-HMPAO) in 20 patients who had undergone a previous median sternotomy and without infectious complications at follow-up. The study included anterior and oblique anterior planar views at 4 and 20 h. SPET of the chest was also carried out at 4 and 20 h. At 4 h, the planar views showed low background vascular activity in the lungs and cardiac region in addition to the sternal uptake, which showed two patterns: homogeneous in five patients and heterogeneous in 15. A long and narrow defect of uptake along the sternal midline was the most characteristic finding. At 4 h, in addition to the background vascular activity in the lungs and cardiac region, the greatest uptake on SPET was in the sternum anteriorly and the marrow spine posteriorly without any focal uptake, allowing visualization of the mediastinum free of focal activity. At 20 h, both the planar and SPET images showed a higher organ-to-background ratio. Knowledge of these post-surgical patterns will make it easier to interpret planar and SPET images when 99Tcm-HMPAO-labelled leukocytes are used in the diagnosis of mediastinitis and sternal infections in patients who had previously undergone median sternotomy. Planar views were better for the assessment of sternal uptake, but SPET views were better for the direct visualization of the mediastinum by eliminating overlapping sternal uptake.

BACKGROUND: The CarboMedics "Top-Hat" supraannular prosthesis was designed to permit the implantation of a larger prosthesis. METHODS: Between June 1993 and November 1996, 127 patients (average age, 61.8+/-10.2 years) received a CarboMedics "Top-Hat" supraannular aortic prosthesis. The average follow-up was 15.7 months, and all surviving patients underwent echocardiographic study. This group is compared with 656 patients in whom a standard CarboMedics prosthesis was implanted and also with 2,927 patients who received other aortic prostheses. RESULTS: Using the standard and the supraannular sizers, there was an average increase of one size in favor of the supraannular prosthesis: 18.9+/-2.8 mm standard versus 20.8+/-2.6 mm supraannular (p < 0.005). For each prosthesis size (19 to 23 mm), the body surface area of the patients in whom a CarboMedics supraannular prosthesis was implanted was significantly smaller than that in those who received a CarboMedics standard prosthesis or any other model. Hospital mortality was 3.9%, and late mortality was 5.5%. The actuarial survival was 86.5%+/-3.9% at 42 months. CONCLUSIONS: Using the CarboMedics supraannular prosthesis allows implantation of a larger prosthesis compared with the standard CarboMedics prosthesis or other models. This advantage is especially important in patients with a small aortic root.

Surgical alterations after median sternotomy can difficult the interpretation of scintigraphic images with Ga67. To analize the use of Ga67 scintigraphy in this patology, we wanted to know the Ga67 distribution in patients who had suffered median sternotomy. We studied 8 patients in the first month after median sternotomy without infection complication and performed planar images and SPECT. Ga67 showed uptake in liver, spleen and bone. Sternal uptake was greater or lesser than liver uptake but always showed an homogeneous distribution. No mediastinum uptake was observed. Surgical wound showed Ga67 uptake during the first week after sternotomy. To know the <

Given the characteristics of ischemic heart disease, this condition is frequently associated with carotid and peripheral artery disease. Cardiac complications of vascular surgery and vascular complications of myocardial revascularization operations are common and severe. However, carotid artery endarterectomy or revascularization procedures for the lower extremities can be combined simultaneously with coronary artery bypass operations with acceptable results. It is difficult to determine whether or not both disorders should be treated surgically in a single stage or in two stages. This decision should be individualized according to the severity of the lesions and the risk of complications if one of these procedures is delayed.

OBJECTIVE: To investigate the long-term performance of aortic valve repair, we analyzed the results obtained in a 22-year period in patients who underwent repair of nonsevere rheumatic aortic valve disease during other valvular procedures. METHODS: Fifty-three patients (mean 40 +/- 11.6 years of age) with predominant rheumatic mitral valve disease had concomitant aortic valve disease in association with serious tricuspid valve disease in 25 of them. Preoperatively, aortic valve disease was considered moderate in 47.2% of the patients and mild in 52.8%. All patients underwent reparative techniques of the aortic valve (free edge unrolling, 44; subcommissural annuloplasty, 40; commissurotomy, 36) at the time of mitral or mitrotricuspid valve surgery. The completeness of follow-up during the closing interval was 100%, with a mean follow-up of 18.8 years (range 8 to 22.5 years). RESULTS: Hospital mortality rate was 7.5%. Of 49 surviving patients, 26 (53.1%) died during late follow-up. The actuarial survival curve including hospital mortality was 35.4% +/- 8.7% at 22 years. For patients who underwent mitral and aortic valve surgery, the actuarial survival curve at 22 years was 32.3% +/- 13%, whereas for patients who had a triple-valve operation the survival was 37.0% +/- 10.1% (p = 0.07). Twenty-five patients underwent an aortic prosthetic valve replacement. Actuarial free from aortic structural deterioration and valve-related complications at 22 years was 25.3% +/- 9.3% and 12.7% +/- 4.8%, respectively. CONCLUSIONS: Long-term functional results of reparative procedures of nonsevere aortic valve disease in patients with predominant rheumatic mitral valve disease have been inadequate at 22 years of follow-up. According to these data, conservative operations for rheumatic aortic valve disease do not seem appropriate.

BACKGROUND: On the basis of a previous experience in a chronic sheep model in which partial mitral allografts remained viable and properly functioning 12 months after operation, we assessed the results obtained by replacing the tricuspid valve with fresh antibiotic-preserved mitral allografts. METHODS: Twenty 3-month-old sheep with a mean weight of 23.7 +/- 2.3 kg underwent cardiopulmonary bypass and had a fresh antibiotic-preserved mitral allograft implanted in the tricuspid position with the heart beating under normothermic conditions. The tricuspid valve apparatus was not excised. After a mean follow-up of 13.2 months, the allograft was evaluated by gross inspection and light and electron microscopy. RESULTS: Nine sheep died of technical causes within the first week after operation and 2 at 4 and 6 months of infective endocarditis of the allograft. The hemodynamic study before heart explantation revealed residual tricuspid incompetence in 3 of the 9 survivors. Macroscopic examination showed flexible valves with no signs of structural deterioration, calcification, or thrombosis. Under light and scanning electron microscopic examination, allografts were almost completely denuded of endothelial cells and showed loosely arranged connective tissue with scarce signs of inflammatory reaction. Despite these findings, allografts were free from major structural damage. CONCLUSIONS: The mitral homograft could be an alternative to replacement of the tricuspid valve with a bioprosthesis or a mechanical prosthesis.

BACKGROUND: The lack of valve rotatability, the structural deterioration, and the rate of valve-related complications with the standard mechanical bileaflet prosthesis led to the development of a new second-generation bileaflet valve in 1986. METHODS: Between January 1989 and March 1994, 1,049 CarboMedics valves were implanted in 859 patients. The rotatability was used in 109 mitral prostheses (21.5%) and in 61 aortic prostheses (11.6%). Follow-up was 97.1% complete, with 3,049 patient-years. RESULTS: The hospital mortality was 6.9% for the mitral group, 3.4% for the aortic group, and 10.7% for the double-valve group (p < 0.005). The actuarial survival curve at 5 years was 77.3% +/- 3.6%, 90.1% +/- 2.5%, and 79.2% +/- 3.7% (p = 0.0003), freedom from thromboembolism was 89.1% +/- 3.6%, 87.1% +/- 3.8%, and 68.8% +/- 8.2%, freedom from reoperation was 95.9% +/- 1.4%, 98.9% +/- 0.6%, and 94.9% +/- 2.4%, and freedom from valve-related complications was 68.8% +/- 4.1%, 79.5% +/- 3.5%, and 55.3% +/- 5.9% after mitral, aortic, and mitral and aortic valve replacement, respectively. There were five episodes of valve thrombosis, but no structural deterioration occurred. CONCLUSIONS: The clinical performance of the CarboMedics valve is quite satisfactory, with a low incidence of valve-related mortality and morbidity. The rotatability feature was useful when the native valve was preserved or for repeat valve replacement.

A total of 970 adult patients undergoing cardiovascular operations during a 1-year period were eligible for a case-control study on the risk factors for nosocomial infection. Cases were defined as patients in whom a postoperative infection developed. Every case was paired with one uninfected subject. Nosocomial infection occurred in 89 (9.2%) patients. A total of 120 episodes of infection were diagnosed (1.3 episodes per patient). The infection ratio was 12.4%. Surgical site infection was the most common (5.6%), followed by pneumonia (3.2%), urinary tract infection requiring the use of intravenous antibiotics (1.8%), deep surgical site (0.9%), and bacteremia (0.7%). Advanced age, urgent intervention, duration of surgical procedure, blood transfusion, and use of invasive procedures (urinary catheter, chest tubes, nasogastric tube passage) were significantly associated with infection in the bivariate analysis. Nosocomial infection resulted in a significant increase in the length of hospital stay. Cases showed an almost fivefold greater risk of death than controls (odds ratio, 4.73; 95% confidence interval, 1.11 to 6.83; p = 0.009). Age older than 65 years, female sex, and mode of surgical intervention were selected in the multivariate analysis for patients undergoing cardiac operations, whereas general anesthesia or assisted ventilation, central venous catheter, and blood transfusion were the variables selected for patients undergoing operation for vascular disorders. In summary, the recognition of risk factors for postoperative infection in patients undergoing cardiovascular surgical procedures may contribute to improve their prognosis and to more organized surveillance and control activities in the hospital environment.

BACKGROUND: The Monostrut valve is a pyrolytic carbon, tilting-disc prosthesis with no welds. After the first implantation in Spain in May 1983, the Spanish Monostrut Study Group was established to evaluate prospectively the performance of the valve using uniform protocols. METHODS: During a 10-year period, 8,599 Monostrut valves were implanted in 7,317 patients in 22 centers. Mean age was 53.3 +/- 11 years. Of the total group, 3,229 underwent aortic valve replacement, 2,806 had mitral valve replacement, and 1,282 had double valve replacement. Follow-up was 96% complete, with a mean period of 4.3 years and a total of 29,155 patient-years. RESULTS: The operative mortality rate was 7.2%. The 10-year probability of freedom from valve-related complications and linearized rates (event/100 patient-years in parentheses) were as follows: structural deterioration, 100% (0); nonstructural dysfunction, 96% +/- 0.5% (0.51); thromboembolism, 82.9% +/- 1.5% (1.32); anticoagulant-related hemorrhage, 87.6% +/- 1.4% (0.98); and prosthetic valve endocarditis, 96.1% +/- 0.5% (0.48). There were five obstructive valve thromboses (0.017/100 patient-years). Actuarial freedom from reoperation was 95% +/- 0.5% at 10 years. Actuarial freedom from all valve-related morbidity was 70.2% +/- 1.6%; freedom from all valve-related morbidity and mortality (including operative and sudden deaths) was 62.6% +/- 2% (70.1% +/- 2% for aortic valve replacement, 56.9% +/- 2% for mitral valve replacement, and 59.8% +/- 3% for double valve replacement; p < 0.0001). Clinically, 5,988 patients (94%) are in New York Heart Association class I-II.

Surgical anterior and superior fixation to the diaphragam of a segment of the greater curvature of the stomach simplifies the technical performance of harvesting the right gastroepiploic artery for coronary bypass grafting. Gastropexy avoids objections to the use of this pedicled arterial graft, such as the prolonged dissection time, the limited length of the conduit and the potential damage when abdominal surgery is later required.
