Venous thromboembolism after aesthetic surgeries in low-risk patients without hypercoagulability.

Venous thromboembolism (VTE) is a serious but rare complication of aesthetic surgery, with an incidence of 0.017% for liposuction and 0.01%-0.

TME-targeted approaches of brain metastases and its clinical therapeutic evidence.

The tumor microenvironment (TME), which includes both cellular and non-cellular elements, is now recognized as one of the major regulators of the development of primary tumors, the metastasis of which occurs to specific organs, and the response to therapy. Development of immunotherapy and targeted therapies have increased knowledge of cancer-related inflammation Since the blood-brain barrier (BBB) and blood-cerebrospinal fluid barrier (BCB) limit immune cells from entering from the periphery, it has long been considered an immunological refuge. Thus, tumor cells that make their way "to the brain were believed to be protected from the body's normal mechanisms of monitoring and eliminating them.

Mini-invasive technique of sclerotherapy with talc in chronic seroma after abdominoplasty - a case report and literature review.

The formation of a seroma after abdominoplasty is one of the most common complications faced by plastic surgeons. A 59-year-old man underwent lipoabdominoplasty and developed a large subcutaneous seroma that persisted for 7 months. Percutaneous sclerosis with talc was performed.

Evaluation of the pulmonary function of patients with severe coronavirus 2019 disease three months after diagnosis.

There are few data regarding the repercussion in the pulmonary function of patients who had severe or critical COVID-19 pneumonia. The objective was to describe these patients' pulmonary function and establish an association with the severity of the disease (patients with severe or critical pneumonia), the presence of comorbidities, the tomographic involvement and the persistence of dyspnoea. Fifty-five patients were included, 40 (73%) male, media of age 54.

Cross-country connectedness in inflation and unemployment: measurement and macroeconomic consequences.

Unlabelled: We bring the notion of connectedness (Diebold and Yilmaz, Int J Forecast 28(1):57-66 2012) to a set of two critical macroeconomic variables as inflation and unemployment. We focus on the G7 economies plus Spain, and use monthly data-high-frequency data in a macro setting-to explore the extent and consequences of total and directional volatility spillovers across variables and countries. We find that total connectedness is larger for prices (58.

[Diffusing capacity for carbon monoxide, guidelines for interpretation].

The diffusing capacity for carbon monoxide (DLCO) is, after spirometry the standard and noninvasive pulmonary function test of greater clinical use. However, there are substantial errors in the interpretation of the physiological significance of the DLCO, its derived measures and, therefore the clinical significance of its alterations. In addition to the use of different nomenclatures, other sources of confusion have contributed to some negative view of the test.

Spirometry reference values for an andean high-altitude population.

Unlabelled: We compared the spirometric values of people living at High Altitude at the Andean Plateau with those predicted for lowland population.

Rationale: Spirometry reference values are not yet available for the millions of people living at high altitude in the Andean High Plateau.

Objective: To obtain spirometric prediction equations from a healthy subset of adults living in Argentina at 3440m above sea level.

Anterior cruciate ligament reconstruction with 4-strand hamstring autograft and accelerated rehabilitation: a 10-year prospective study on clinical results, knee osteoarthritis and its predictors.

Purpose: Analysis of long-term clinical and radiological outcomes after anterior cruciate ligament (ACL) reconstruction with special attention to knee osteoarthritis and its predictors.

Methods: A prospective, consecutive case series of 100 patients. Arthroscopic transtibial ACL reconstruction was performed using 4-strand hamstring tendon autografts with a standardized accelerated rehabilitation protocol.

Regeneration of hamstring tendons after anterior cruciate ligament reconstruction.

Purpose: Primary aim of the study was analysis of hamstring tendon regeneration after anterior cruciate ligament reconstruction (ACLR). Secondary aim was analysis of isokinetic muscle strength in relation to hamstring regeneration. The hypothesis was that regeneration of hamstring tendons after ACLR occurs and that regenerated hamstring tendons contribute to isokinetic hamstring strength with regeneration distal to the knee joint line.

Long-term results of surgical decompression of chronic exertional compartment syndrome of the forearm in motocross racers.

Background: Chronic exertional compartment syndrome (CECS) is occasionally observed in the forearm flexor muscles of motocross racers. Long-term results of fasciectomy and fasciotomy for this syndrome are scarce.

Purpose: To study the long-term effects of 2 surgical techniques for forearm flexor CECS.

Remodelling of human hamstring autografts after anterior cruciate ligament reconstruction.

Purpose: Histological analysis of the remodelling process of human hamstring tendon (HT) grafts after standardized anterior cruciate ligament reconstruction (ACLR) with an accelerated rehabilitation protocol.

Methods: Sixty-seven patients underwent retrieval of mid-substance biopsies after clinically successful hamstring autograft ACLR. Samples were allocated to one of three groups depending on the time point of retrieval: group 1 (6-12 months; n = 15), group 2 (13-24 months; n = 16) and group 3 (>24 months; n = 11).

Supramaximal flows: comparison between asthmatics and patients with chronic obstructive pulmonary disease.

Background: The major motive that prompted this study was to investigate whether or not the differences in supramaximal flow (SF) behavior between patients suffering from asthma and patients suffering from chronic obstructive pulmonary disease (COPD) might aid in clarifying the differences in the physiopathology of the two diseases.

Objectives: The aim of the present study was therefore to compare SFs in asthma and COPD patients with similar degrees of air-flow limitation.

Methods: Twelve asthmatic patients were individually matched with 12 COPD patients by forced expiratory volume during the first second (FEV(1)) as a percent (±5%) of the reference value (ΔFEV(1)) and by age (±4 years).

Initial clinical management of symptomatic adult patients during influenza A (H1N1) epidemics.

Background: Pandemic influenza A (H1N1) has emerged rapidly in Argentina since May 2009. Preliminary comparisons with seasonal influenza suggest that H1N1 disproportionately affects younger patients, generally causing mild disease, but in a minority of cases can be lethal.

Objective: The aim of this study was to develop a clinical tool for the initial management of patients with influenza-like syndrome, within the context of the novel H1N1 virus epidemic, to detect patients who need further investigation (e.

Transient expiratory flow interruptions (TEFI) increase expiratory flow in acute asthma exacerbation.

We have shown that expiratory flows increase when expirations are rapidly interrupted in stable asthmatic patients. We hypothesized that a similar increase could be obtained in patients with acute exacerbation of bronchial asthma treated in the Emergency Room. A total of 30 asthmatic patients were randomly allocated into two groups, the study and the control groups.

Chronic deep posterior compartment syndrome of the leg in athletes: postoperative results of fasciotomy.

The present study evaluates the efficacy of two treatment regimens in individuals possibly suffering from chronic exercise induced compartment syndrome (CECS) of the deep posterior compartment of the leg. We hypothesised that the current method of fasciotomy of the deep posterior compartment of the leg is a procedure with a limited success rate. Dynamic intra-compartmental pressure measurements were applied to 46 patients that had symptomatology of a posterior CECS.

[Double-sided juvenile osteochondritis dissecans of the lateral femoral condyle in a 15-year-old boy].

A 15-year-old boy of Turkish origin presented with a painful swollen left knee. An X-ray revealed osteochondritis dissecans of the lateral femoral condyle. Arthrotomy was performed and the fragment was fixated with tissue glue and 2 absorbable pins.

Embolism of the popliteal artery after anterior cruciate ligament reconstruction: a case report and literature review.

Arterial complications after anterior cruciate ligament reconstruction (ACLR) are rare. We present a case report of a 44-year-old male patient with a subtotal occlusion of the popliteal artery, with sensory loss in the foot, 17 days after ACLR. Embolectomy and anticoagulant therapy led to full recovery of the peripheral arterial circulation.

Pseudoaneurysm of the popliteal artery after anterior cruciate ligament reconstruction with bicortical tibial screw fixation.

We present a case report of a pseudoaneurysm of the popliteal artery after anterior cruciate ligament reconstruction using a bicortical tibial screw fixation 12 days after surgery. Surgical exploration and repair of an intimal lesion of the popliteal artery was performed. At 4-months' follow-up, there was still sensory loss in areas of the saphenous, medial plantar, calcaneal, and superficial peroneal nerves.

Supramaximal flow in asthmatic patients.

In normal subjects supramaximal flows (SF) are known to be correlated with flow limitation. To further understand the mechanisms involved in SF this correlation and the influence of salbutamol and methacholine administration on SF have been investigated in asthmatic subjects. Protocol A involved obtaining basal maximal expiratory flow/volume curves and interrupted curves through a fast valve from 36 asthmatic patients.

[Argentine consensus on sleep-related respiratory disorders].

Due to the increased interest of the medical community in sleep disorders an experts meeting was called to establish common criteria for diagnosis, treatment and management of these disorders. Adult prevalence of sleep apnea/hypopnea syndrome (SA/HS) is about 2-4% and increases in the elderly. Snoring and excessive daytime somnolence (EDS) are habitual symptoms.

Relationship between supramaximal flows and flow-limiting mechanisms.

The aim of this study was to evaluate the relationship between supramaximal flows (SF) and indices of airway mechanics. We studied 26 asymptomatic young subjects (13 smokers, mean +/- SD 15.9 +/- 6.

Effects of inhaled platelet activating factor on bronchial responsiveness in patients with symptomatic and asymptomatic pulmonary embolism.

To determine the possible role of platelet-activating factor (PAF) in pulmonary embolism (PE), the reactivity of the airways to inhaled PAF, using doses ranging from 6.25 to 400 micrograms, was examined in 24 patients with a past episode of PE. Twelve of these patients had experienced acute respiratory insufficiency during the episode (with or without additional symptoms).

Hygroscopic condenser humidifier as a solution to nasal dryness due to nasal CPAP treatment for obstructive sleep apnea syndrome.

We report an apparent solution to nasal dryness for patients with obstructive sleep apnea syndrome treated with nasal continuous positive airway pressure (CPAP) when a hygroscopic condenser humidifier is introduced into the CPAP circuit. Six patients underwent a 5-h test period of nasal CPAP therapy with a mask containing a hygroscopic humidifier. The water vapor showed a statistically significant increase in both inspired and expired gases.
