Impacto del diagnóstico de melanoma sobre la fotoprotección

El conocimiento sobre los peligros de la exposición solar no siempre se traduce en cambios en el comportamiento. Esto es particularmente alarmante en pacientes de alto riesgo. Este trabajo pretende evaluar el impacto del diagnóstico de melanoma en los conocimientos, actitudes y hábitos sobre fotoprotección; y analizar qué factores pueden influir en el cambio de hábitos de fotoprotección

Primary Melanoma of the Small Intestine with a Metastatic Lymph Mass in the Inguinal Canal: A Case Report

Objectives: We report a case of primary melanoma of the small intestine. Primary intestinal melanoma (PIM) is an extremely rare neoplasm for which the cause is unknown. Materials and methods: A 67-year-old man was admitted to our department due to abdominal pain, constipation, a large, hard inguinal mass and severe anaemia. Results: After laboratory data, imaging techniques and histopathological examination, the diagnosis was confirmed. A surgical resection of the intestinal neoplasm, treatment with BRAF inhibitors and radiation therapy to the inguinal mass were performed. Conclusion: PIM is rare and it is usually difficult to establish its exact origin

Postural orthostatic tachycardia syndrome and other related dysautonomic disorders after SARS-CoV-2 infection and after COVID-19 messenger RNA vaccination

The COVID-19 pandemic has caused a challenge for our society due to the post-acute sequelae of the disease. Persistent symptoms and long-term multiorgan complications, known as post-acute COVID-19 syndrome, can occur beyond 4 weeks from the onset of the COVID-19 infection. Postural orthostatic tachycardia syndrome (POTS) is considered a variety of dysautonomia, which is characterized by chronic symptoms that occur with standing and a sustained increase in heart rate, without orthostatic hypotension. POTS can lead to debilitating symptoms, significant disability, and impaired quality of life. In this narrative review, the etiopathogenic basis, epidemiology, clinical manifestations, diagnosis, treatment, prognosis, and socioeconomic impact of POTS, as well as other related dysautonomic disorders, after COVID-19 infection and SARS-CoV-2 postvaccination, were discussed. After a search conducted in March 2023, a total of 89 relevant articles were selected from the PubMed, Google Scholar, and Web of Science databases. The review highlights the importance of recognizing and managing POTS after COVID-19 infection and vaccination, and the approach to autonomic disorders should be known by all specialists in different medical areas. The diagnosis of POTS requires a comprehensive clinical assessment, including a detailed medical history, physical examination, orthostatic vital signs, and autonomic function tests. The treatment of POTS after COVID-19 infection or vaccination is mainly focused on lifestyle modifications, such as increased fluid and salt intake, exercise, and graduated compression stockings. Pharmacotherapy, such as beta-blockers, fludrocortisone, midodrine, and ivabradine, may also be used in selected cases. Further research is needed to understand the underlying mechanisms, risk factors, and optimal treatment strategies for this complication

The physical examination revealed large erythematous-brownish plaques with a granulomatous appearance, polypoid lesions and areas of ulceration. In addition, Mycobacterium tuberculosis culture and serum QuantiFERON® TB Gold were negative. The patient was diagnosed to have metastatic Crohn’s disease which is an uncommon complication of Crohn’s disease.Ye
