Pulmonary sequestration 2: left lower lobe.

Pulmonary sequestration is a rare congenital anomaly, characterized by aberrant lung tissue supplied by an aberrant systemic artery or arteries coursing within the inferior pulmonary ligament. The intralobar variety is the most frequent form. Clinical presentation may include recurrent haemoptysis and infection.

Barriers to epilepsy surgery in pediatric patients: A scoping review.

Rationale: Up to 40% of pediatric epilepsy cases are drug-resistant and associated with neurocognitive, psychosocial, developmental comorbidities, and risk of early mortality. Epilepsy surgery (ES) may be considered after the failure of two anti-seizure medications (ASM) to provide patients with the opportunity to attain seizure freedom. However, only a small proportion of eligible patients receive surgical treatment.

An overview and critique of the use of cumulative sum methods with surgical learning curve data.

Cumulative sum (CUSUM) plots and methods have wide-ranging applications in healthcare. We review and discuss some issues related to the analysis of surgical learning curve (LC) data with a focus on three types of CUSUM statistical approaches. The underlying assumptions, benefits, and weaknesses of each approach are given.

Relationship Between Genetic Risk and Age of Diagnosis in Systemic Lupus Erythematosus.

Objective: Specific risk alleles for childhood-onset systemic lupus erythematosus SLE (cSLE) vs adult-onset SLE (aSLE) patients have not been identified. The aims of this study were to determine if there is an association (1) between non-HLA-related genetic risk score (GRS) and age of SLE diagnosis, and (2) between HLA-related GRS and age of SLE diagnosis.

Methods: Genomic DNA was obtained from 2001 multiethnic patients and genotyped using the Immunochip.

Outcomes of the anatomical repair in patients with congenitally corrected transposition of the great arteries: lessons learned in a high-volume centre.

Objectives: The physiological repair of the congenitally corrected transposition of the great arteries (ccTGA) has been associated with a long-term risk of the right ventricular dysfunction and tricuspid valve regurgitation. On the other side, the anatomical repair with the restoration of the left ventricle in a systemic position has been hypothesized to improve long-term outcomes. The aim of this study was to determine the results of the anatomical repair.

Differences and similarities in risk factors for postoperative acute kidney injury between younger and older adults undergoing cardiac surgery.

Objectives: Acute kidney injury is a frequent complication after cardiac surgery. The purpose of this study was to assess the risk factors for acute kidney injury in patients ≤60 years of age undergoing cardiac surgery and to compare these risk factors with those identified in patients ≥65 years of age.

Methods: From 2010 to 2012, 1253 patients ≤60 years (mean age 52 ± 9 years) and 2488 patients ≥65 years (mean age 74 ± 6 years) underwent cardiac surgery.

Long-term results after surgical treatment of paravalvular leak in the aortic and mitral position.

Objectives: The aim of this study was to determine immediate results and long-term outcomes after surgical management of paravalvular leak (PVL).

Methods: Between 1995 and 2012, a total of 190 patients underwent primary surgical repair (n = 142) or valve replacement (n = 48) for a PVL at our institution. The PVL was mild in 6 (3%) patients, moderate in 85 (45%), moderate to severe in 84 (44%), and severe in 15 (8%).

Redefining dermatomyositis: a description of new diagnostic criteria that differentiate pure dermatomyositis from overlap myositis with dermatomyositis features.

Dermatomyositis (DM) is a major clinical subset of autoimmune myositis (AIM). The characteristic DM rash (Gottron papules, heliotrope rash) and perifascicular atrophy at skeletal muscle biopsy are regarded as specific features for this diagnosis. However, new concepts are challenging the current definition of DM.

Imaging in cardiac cell-based therapy: in vivo tracking of the biological fate of therapeutic cells.

Clinical trials in cardiac cell-based therapy (CBT) have demonstrated the immense potential of stem progenitor cells (SPCs) to repair the injured myocardium. The bulk of evidence so far has shown that CBT can lead to structural and functional improvements. Unresolved issues remain, however, including gaps in the understanding of mechanisms and mixed results from CBT trials.

Heterogeneity of autoantibodies in 100 patients with autoimmune myositis: insights into clinical features and outcomes.

The objective of this study was to determine the prevalence, mutual associations, clinical manifestations, and diagnoses associated with serum autoantibodies, as detected using recently available immunoassays, in patients with autoimmune myositis (AIM). Sera and clinical data were collected from 100 patients with AIM followed longitudinally. Sera were screened cross-sectionally for 21 autoantibodies by multiplex addressable laser bead immunoassay, line blot immunoassay, immunoprecipitation of in vitro translated recombinant protein, protein A assisted immunoprecipitation, and enzyme-linked immunosorbent assay.

Thromboembolism complicating the treatment of lupus anticoagulant hypoprothrombinemia syndrome.

Lupus anticoagulant hypoprothrombinemia syndrome (LAHPS) is a rare disorder characterized by a bleeding tendency due to factor II deficiency associated with the presence of lupus anticoagulant (LAC) autoantibodies. We describe a patient with systemic lupus erythematosus and LAHPS in whom successful treatment of central nervous system bleeding due to severe factor II deficiency was followed by a major thromboembolic complication. Literature review revealed 2 other patients with LAHPS who developed thrombosis resulting from the treatment of factor II deficiency.

Fetal atrial flutter: diagnosis, clinical features, treatment, and outcome.

Objectives: To assess clinical features, treatment efficacy, and outcome of fetal atrial flutter.

Study Design: All atrial flutter cases seen in our unit between 1988 and 1995 were reviewed retrospectively and compared with the pooled data of 37 echocardiographically documented and published cases.

Results: Atrial flutter was found in 15 of 49 (30.

Corneal endothelial cell density in glaucoma.

Purpose: We studied corneal endothelial cell density in patients with glaucoma.

Methods: One hundred two patients with glaucoma were compared with 52 patients without glaucoma of the same age group. Exclusion criteria included history of either corneal disease, ocular inflammation, trauma, or surgery other than peripheral iridectomy.

A novel anti-microfilament antibody, anti-135 kD, is associated with Raynaud's disease, undifferentiated connective tissue disease and systemic autoimmune diseases.

We report herein the characterization of a human IgG antibody reactive with a nonmuscle 135 kD microfilament-associated protein, anti-135 kD. Using nonmuscle epithelial PtK2 cells as substrate in indirect immunofluorescence, we identified a distinctive pattern of reactivity with microfilaments in sera from 12 of 165 (7.3%) patients investigated for systemic autoimmune diseases and in only 2 of 171 (1.
