RESUMO
We report a case of a 63-year-old male patient with multiple cardiovascular risk factors and previous myocardial infarction who was referred to the emergency department on September 2023 with symptoms and clinical and biological data consistent with an acute coronary event. A coronary angiography revealed severe ostial stenosis of the left anterior descending artery (LAD) and intrastent thrombotic occlusion in the first two segments of the LAD. Two drug-eluting stents were implanted and the patient was discharged when hemodynamically stable; however, three weeks later, he returned to the emergency department complaining of fever, anterior chest pain, dyspnea at rest, and high blood pressure values at home. High levels of troponin T, C-reactive protein, and NT-proBNP were detected and blood cultures showed methicillin-resistant Staphylococcus aureus. The computed tomography (CT) examination showed a saccular dilatation had developed between two fragments of a stent mounted at the level of the LAD, surrounded by a hematic pericardial accumulation. LAD pseudoaneurysm ablation and a double aortocoronary bypass with inverted saphenous vein autograft were performed and the patient showed a favorable postoperative evolution. In this case, surgical revascularization was proven to be the appropriate treatment strategy, demonstrating the need to choose an individualized therapeutic option depending on case-specific factors.
RESUMO
Vertebral limbus is a condition characterized by the intraspongious herniation of a portion of the nucleus pulposus. It is often asymptomatic, but it can sometimes cause nonspecific symptoms such as local pain and muscle spasm, or, in rare cases, radiculopathies, which is why it can be confused with vertebral fractures, spondyloarthropathies, infectious or tumoral processes. Early recognition of this pathology is preferable for a correct diagnosis and adequate treatment, the latter ranging from conservative approaches (such as personalized exercise programs and physical therapy) to surgical interventions reserved for severe cases with nerve compression.
RESUMO
Delayed fracture healing can have devastating functional consequences, including pseudoarthrosis. Many factors can contribute to delayed healing, including decreased vascularity, micro-motion at the fracture site, large fracture gaps, multiple traumas at the same site, compromised metabolic status, surgical complications, and other conditions. A 61-year-old female patient was referred to our hospital with left distal humeral pseudarthrosis, accompanied by chronic pain and disability. Two years prior, the patient suffered a traumatic incident. At another medical facility, the patient underwent open reduction and internal fixation surgery with simultaneous ulnar nerve transposition. She showed favorable postoperative recovery. Unfortunately, approximately one year later, the patient sustained a second trauma to the same arm. This led to peri-implant fracture and post-traumatic aseptic degradation of the osteosynthesis system which was subsequently removed. Twelve months after the last surgery, the patient was referred to our hospital and, after thorough consideration of the therapeutic options, we decided to perform left elbow arthroplasty with left distal humeral reconstruction by using Zimmer's Comprehensive Segmental Revision System. This approach is generally reserved for tumors, and only a handful of cases of megaprostheses for non-tumoral indications have been previously reported. The surgery and perioperative care of our patient were optimal, there were no complications, and the patient recovered arm functionality following rehabilitation.
RESUMO
Coronary arteries have a wide range of anatomical variability, and their spectrum ranges from asymptomatic cases to those predisposed to hemodynamic compromise or even sudden cardiac death. This paper aims to review the classification of coronary artery anomalies (CAAs) and illustrate their imaging characteristics by highlighting the important role of CT coronary angiography. Some of the coronary anomalies usually met in current practice are the high origin coronary artery, multiple ostia, aberrant origin from the opposite/non-coronary Valsalva sinus, single coronary artery, ALCAPA syndrome, duplications of the left anterior descending artery, coronary fistulas, and extracardiac terminations. CT coronary angiography is a non-invasive diagnostic modality for CAAs. The complex anatomy of these anomalies can be accurately described by employing 3D reconstructions and post-processing techniques. Knowledge of the imaging characteristics and potential functional impact of these anomalies is essential for accurate diagnosis and therapeutic planning of patients.
RESUMO
Obesity is an important condition affecting the quality of life of numerous patients and increasing their associated risk for multiple diseases, including tumors and immune-mediated disorders. Inflammation appears to play a major role in the development of obesity and represents a central point for the activity of cellular and humoral components in the adipose tissue. Macrophages play a key role as the main cellular component of the adipose tissue regulating the chronic inflammation and modulating the secretion and differentiation of various pro- and anti-inflammatory cytokines. Inflammation also involves a series of signaling pathways that might represent the focus for new therapies and interventions. Weight loss is essential in decreasing cardiometabolic risks and the degree of associated inflammation; however, the latter can persist for long after the excess weight is lost, and can involve changes in macrophage phenotypes that can ensure the metabolic adjustment. A clear understanding of the pathophysiological processes in the adipose tissue and the interplay between obesity and chronic inflammation can lead to a better understanding of the development of comorbidities and may ensure future targets for the treatment of obesity.

Cutis laxa (CL) or elastolysis is a rare inherited or acquired connective tissue disorder in which the skin becomes inelastic and hangs loosely in folds (Mitra et al., 2013). The clinical presentation and the type of inheritance show considerable heterogeneity (Shehzad et al., 2010). We aimed to present the atypical case of a young male patient diagnosed at 36-year-old with CL with systemic involvement. The complex medical history, with a suspected but unconfirmed progeria at nine months, repeated lung and urinary infections, complicated inguinoscrotal hernia, prostatic hypertrophy, bilateral entropion, colorectal diverticula and heart failure, suggested a systemic genetic disease, but the absence of family history made the diagnosis of CL difficult. The skin biopsy and the characteristic features discovered during anatomopathological exam made possible the positive and differential diagnosis, creating the link between the various organ involvement and CL diagnosis. Because of the age of our patient, of normal growth and mental development, and negative family history, we suspected an autosomal dominant form of CL with early onset and severe manifestation. Of course, we cannot exclude a recessive form, due to the heterogeneity of this disease.
