Unlabelled: The aim of this study is to access magnetic resonance as the imaging modality of choice in differentiation of cerebellopontine angle tumors.
Material And Methods: In period of five years in 53 patients were diagnosed CPA tumors. 31 were women, 22 men, range age 14 to 72 years. All patients were examined on 1.0 Tesla magnetic resonance unit, using T1, PD, T2 WI sequences, and after paramagnetic contrast administration T1 W1 in three ortogonal planes. REZULTS: In 44 (83%) patients were diagnosed acoustic schwannoma (NVIII), and 8 patients of these had Neurifibromatosis Type 2. In 2 (4%) patients were diagnosed trigeminal schwannoma (NV), in 2 (4%) hypogossal schwannoma. By 5 (9%) patients were diagnosed meningiomas. All diagnoses were by histology confirm.
Conclusion: Thanks to its multiplanar and multi-parameters capabilities Magnetic resonance allowed precise location and characterization of CPA tumors. MR is the imaging modality of choice for preoperative work-up of cerebellopontine angle tumors.

The socioecological conditions of Mexican regions are conducive to the spread of vector-borne diseases. Although there are established treatment guidelines for dengue and rickettsiosis, diagnosis is complicated. The objective of this work was to identify epitopes of Rickettsia and dengue virus that could be used in serology screening against vector-borne diseases.

Background: Heart failure (HF) is a chronic, progressive condition where the heart cannot pump enough blood to meet the body's needs. In addition to the daily challenges that HF poses, acute exacerbations can lead to costly hospitalizations and increased mortality. High health care costs and the burden of HF have led to the emerging application of new technologies to support people living with HF to stay well while living in the community.

Background: Skin cancers, including melanoma and keratinocyte cancers, are among the most common cancers worldwide, and their incidence is rising in most populations. Earlier detection of skin cancer leads to better outcomes for patients. Artificial intelligence (AI) technologies have been applied to skin cancer diagnosis, but many technologies lack clinical evidence and/or the appropriate regulatory approvals.

Background: Diabetes affects half of the patients with cystic fibrosis who are aged 30 years and older. Diabetes progresses asymptomatically over a long period of time. Two treatment options are possible: start insulin as soon as cystic fibrosis diagnosis is made with the additional constraints of cystic fibrosis or wait while monitoring the patient's clinical condition and start insulin when diabetes symptoms develop and therefore later.
