RESUMEN

OBJECTIVES: To assess the usefulness of the neutrophil-to-lymphocyte ratio (NLR) as a predictive factor of acute mesenteric ischemia (AMI) in patients presenting at the emergency department (ED) with acute abdominal pain. METHODS: This is a retrospective case-control study of patients older than 16 years admitted to the ED with acute abdominal pain with CT and histologic confirmation. The study group corresponded to patients with abdominal CT with radiological signs of AMI. The control group corresponded to patients with non-AMI findings in abdominal CT. Association measurements of NLR with radiological signs were compared with a paired-sample t test, and multivariate regression performed to analyze potential correlations. To assess the diagnosis capacity of NLR, ROC curves were calculated. RESULTS: A total of 61 patients were included (32 cases and 29 controls). The cases of AMI showed higher mortality (43.8% vs 6.9%, p < 0.01) and higher NLR on the limit of statistical significance (13.8 vs 8.7, p = 0.053). Patients with AMI due to occlusion of the superior mesenteric artery (SMA) showed a higher NLR (8.3 vs 22.3, p < 0.001). The area under the curve (AUC) of the NLR for AMI due to occlusion of the SMA was 0.88 (95% CI 0.7-1.0, p = 0.001). No patient with NLR < 5 presented AMI due to occlusion of the SMA. An NLR of 12.8 showed a sensitivity of 92% and a specificity of 74% for AMI due to occlusion of SMA. CONCLUSIONS: The NLR is a useful parameter of AMI of arterial origin due to occlusion of the SMA; it can help the clinician to raise suspicion of this diagnosis and the interpreting radiologist in the acquisition protocol for the CT study and would alert for an early surgical treatment.

RESUMEN

INTRODUCTION: Malnutrition and sarcopenia are associated with increased risk of adverse events and worse outcome in hospitalised patients. Ultrasonography is a useful tool in the assessment of body composition. PATIENTS AND METHODS: Twenty-three patients admitted to a hospital ward were recruited. Ultrasonographic variables of muscle tissue and adipose tissue were collected, as well as their variation during admission. These were correlated with anthropometric, clinical and analytical data. RESULTS: We observed a correlation of ultrasound measurements with length of hospitalisation (maximum preperitoneal fat -0.585, rectus femoris thickness - RF -0.539, RF area -0.540), frailty (RF -0.599) and dependency (RF 0.628). RF contractile capacity correlated with reported weekly exercise (0.642). CONCLUSION: RF and preperitoneal fat thickness correlate with the number of days of admission and functional capacity, emerging as prognostic variables.

RESUMEN

BACKGROUND AND OBJECTIVE: The aim of our study is to define the role of Pulsed-Doppler (PW-Doppler) Ultrasound of the Common Femoral Vein (CFV) in the assessment of dilatation Inferior Vena Cava (IVC), probability of Pulmonary Hypertension (PH), Tricuspid Regurgitation (TR), and Tricuspid annular plane systolic excursion (TAPSE). METHODS: This is a prospective two-hospital study in 74 patients admitted with acute heart failure (AHF). We performed PW-Doppler ultrasound of the common femoral vein, Point of Care (POC) cardiac ultrasonography and assessment of the IVC at the time of admission, as well as PW-Doppler and ultrasound of the IVC at hospital discharge. RESULTS: The detection of a pulsatile flow (138 scans) had an excellent ROC curve for the detection of IVC greater than 2cm (AUC 0.931, Sn 95%, Sp 90%, PPV 93%, NPV 94%) with an Odds Ratio (OR) of 211.2 (95% confidence interval 48.13-926.72). The pulsatility of the flow also had the highest performance in the detection of PH (AUC 0.8, Sn 95%, Sp 64%, PPV 84%, NPV 84%) and in the detection of moderate-severe TR (AUC 0.79, Sn 95%, Sp 67%, PPV 88%, NPV 78%). If the flow is continuous, we can reasonably rule out diminished TAPSE (NPV 89%). CONCLUSSION: Detection of PW-Doppler flow of the CFV may be an alternative window for the detection of an IVC dilation of 2cm, significant TR, and the likelihood of high PH in acute heart failure. It also allows us to reasonably rule out dysfunction of the right ventricle in cases of normality in these patients.

RESUMEN

BACKGROUND: Superficial venous thrombosis (SVT) is a common clinical problem across various treatment settings. SVT shares risk factors with deep venous thrombosis (DVT) and carries a risk of thromboembolic complications, greater than previously expected. Little is known about the pathophysiology, resolution and recurrence of this disease. OBJECTIVES: The objective of the present study was to describe the natural course of SVT, and factors correlated with the progression or resolution of the thrombus. METHODS: We included 218 patients with a recent diagnosis of SVT that were consecutively referred to a thrombosis clinic from the Emergency Department (ED) between January 2016 and April of 2018. RESULTS: The resolution of the thrombus prior to discharge was correlated to gender (female 73.8% vs. male 57.5%, p = 0.015), presence of varicose veins (62.4% vs. 46.4, p = 0.026), absence of family or personal history of thrombosis (98% vs. 91.3%, p = 0.021). The factor most correlated to thrombus resolution prior to discharge was the result of the 2nd ultrasound (improvement 83.9% vs. 16.1%, p < 0.001) immediately after initiation of heparin treatment. In the multivariate analysis, a high thrombus burden in the early follow-up ultrasound was the most significant predictive variable with prior to discharge recanalization (B = 20.9, 95% CI 9.8-44.7; p < 0.001). CONCLUSION: The follow-up of SVT with duplex lower extremity ultrasound allows us to monitor the evolution and early identify residual thrombosis, as a marker of hypercoagulability and recurrence. This study offers new perspectives for future research, necessary to improve the management of this disease, to reduce long-term complications.

RESUMEN

BACKGROUND: Venous thromboembolism is a common disease seen in the emergency department and a cause of high morbidity and mortality, constituting a major health problem. OBJECTIVES: To assess the potential benefit of follow-up ultrasound of patients who attended the emergency department with suspected superficial venous thrombosis or deep venous thrombosis and were found to have an initial negative whole-leg (or arm) ultrasound study. METHODS: This retrospective study included patients aged 18 years or older who were consecutively referred to a thrombosis clinic from the emergency department, with abnormal D-dimer test and moderate to high pre-test probability of deep venous thrombosis (Well's score ≥ 1), but a negative whole-leg (or arm) ultrasound. Demographic characteristics, symptom duration, laboratory and ultrasound data were recorded. At one-week follow-up, an experienced physician repeated ultrasound, and recorded the findings. RESULTS: From January 2017 to April 2018, 54 patients were evaluated. The mean age was 66.8 years (SD 15.0) and 63% were women. The average D-dimer was 2159.9 (SD 3772.0) ng/mL. Ultrasound abnormalities were found in 12 patients (22.2%; 95% confidence interval of 12.5 to 36.0%), with 4 patients having proximal deep venous thrombosis, distal deep venous thrombosis in 2 patients and superficial venous thrombosis in 6 patients. We did not find any significant differences in demographic characteristics, venous thromboembolism risk factors or laboratory parameters between patients with negative and positive follow-up ultrasound. CONCLUSIONS: These preliminary findings suggest that a negative whole-leg (or arm) ultrasound in addition to an abnormal D-dimer in moderate to high deep venous thrombosis pretest probability patients, might be an insufficient diagnostic approach to exclude suspected deep venous thrombosis or superficial venous thrombosis. Confirmation of this higher than expected prevalence would support the need to repeat one-week ultrasound control in this population.

RESUMEN

BACKGROUND: Despite the improvement in the prognosis of lupus nephritis (LN), the cardiovascular morbimortality remains high. The early recognition and remission of flares, while trying to avoid the metabolic adverse effects of medication, must be mandatory. AIM: The aim of our study was to assess the cardiovascular (CV) risk profile in a cohort of lupus patients with preserved kidney function after a nephritis episode, compared to patients without a nephritis flare. METHODS: 130 patients diagnosed of SLE (32 with previous nephritis flare and 98 without) were studied in order to evaluate the CV risk profile, despite the preserved kidney function. RESULTS: The most prevalent risk factors were sedentary lifestyle (57.6%), overweight/obesity (38.3%) and dyslipidemia (36%), followed by smoking (32%) and hypertension (16%). Though more than a half (53.1%) was taking CV medication, a high percentage did not reach a therapeutic target value, especially regarding obesity (11.5%) and cholesterol levels (LDL-C of 16%). The prevalence of dyslipidemia (53.1% vs 30.6%), smoking (46.6% vs 27.5%), left ventricular hypertrophy (LVH) (21.4% vs 6.4%) and lower HDL-C (48.6mg/dL vs 55.4mg/dL) were significantly different in the group with previous nephritis flare. Moreover, young patients with lupus nephritis, received more pulses of corticosteroids and cyclophosphamide, had higher prevalence of hypertension, LVH, higher proteinuria, hospital admissions and waist circumference, constituting the subgroup of patients with greater aggregation of CV risk factors. CONCLUSIONS: Patients with previous nephritis flare showed a poor control of CV risk factors despite the preserved renal function, these patients would require a closer therapeutic management.

RESUMEN

Necrotising fasciitis (NF) is a rare infection of the subcutaneous tissue, known to be rapidly progressive and potentially fatal. Patients with systemic lupus erythematosus (SLE) may be predisposed to this condition, and early clinical recognition can be difficult. We report a case of necrotising fasciitis in a 26-year-old woman with SLE. She presented with painful swelling of her left leg, then developed clinical features of septic shock. Emergency debridement was performed. Intraoperative findings revealed NF and cultures grew Pseudomonas aeruginosa. The patient survived after a lengthy hospital admission, following several further debridements complicated by recurrent chest sepsis and multiorgan failure. We also review and discuss the published cases of NF in SLE patients.
