This work presents basic results but relevant cases of linguistic intercomprehension among related Amazonian and Andean languages in three specific contexts: confluence of Pano family languages, confluence of Arawak family languages and confluence of languages of Quechua family. To test the hypothesis, "... languages of the same language family share a basic grammatical organization which allows intercomprehension”, it has been initiated a pilot project with the Arawak languages. However, this process must continue in order to be able to determine if the intercomprehension could be given just as other languages. The first results are positive in their application as teaching strategy in EIB.

We report the case of a 36-year-old male from Ancash, Peru, who attended to a local hospital due to articular pain in the right knee for three years. Diagnosis was not reached in that hospital and months later he visited Hospital Nacional Dos de Mayo in the capital city, where evaluation and treatment for osteoarticular tuberculosis was started after finding a granulomatous inflammatory process in a bone biopsy. Such diagnosis was confirmed later by a positive culture of synovial fluid after a more than 45-month disease period. The atypical presentation, absence of a primary site and diagnostic difficulty of the disease in a country where tuberculosis is still endemic encouraged the publication of this case report.

In public hospitals, the difficulties arising from the lack of logistical resources in the clinical laboratory make quality care even more difficult. The lack of management by processes and the conflicts of interest arising from the proliferation of laboratories that are not certified or accredited make a new vision on this subject necessary. Evidence-Based Laboratory Medicine is a tool from which clinicians, technologists and biologists can benefit. On the other hand, it is necessary that, from the state, the efforts made by the UNAGESP, IETSI, SIS, INACAL, SUSALUD, the Ombudsman's Office, the Comptroller General's Office of the Republic, professional associations and private companies to improve the management of the clinical laboratory be agreed upon.

OBJECTIVE: To assess the relationship between the postpartum oral glucose tolerance test (PPOGTT) and fetal macrosomia and its usefulness as a retrospective diagnostic method of gestational diabetes. DESIGN: Prospective case –control study. MATERIAL AND METHODS: Mothers with macrosomic infants (n = 71) and controls (n = 71) were studied. PPOGTT was determined in all of them using 100 grams of glucose 8 to 48 hours postpartum. Data processing used SPSS 10,0. RESULTS: Abnormal PPOGTT is a risk factor to fetal macrosomia with an adjusted odds ratio (OR) 5,9 (95%CI 2,6-13,4). There is association with a previous history of macrosomia OR 15,7 (95CI 1,9-123,6) and with prenatal control OR 5,7 (95%CI 1,2-26,8). CONCLUSIONS: PPOGTT may identify a subset of women with macrosomic infants who had gestational diabetes; we may consider it a retrospective diagnostic test.

Mycoplasma haemofelis is the most pathogenic haemotropic species that affects felines by parasitizing red blood cells and inducing a haemolytic process that can lead to anaemia. The present study aimed to determine the prevalence of this infection in domestic felines from the city of Pereira, Risaralda, Colombia. Samples from 104 domestic felines between 1 and 10 years of age were analysed. Blood samples were taken for cytological (haematological parameters) and molecular analysis by PCR. Additionally, the possible risk factors associated with the presence of M. haemofelis (age, sex, vaccination status and geographical area of origin) were evaluated. The prevalence by molecular analysis was 80.8%, while it was 80.7% with the Giemsa stain and 81.7% with the Wright stain, and the youngest animals (1-2 years) being the most affected. A significant statistical correlation (p=0.0038) of age w...

Computed tomography (CT) is a breakthrough technology used in medicine for diagnostic diseases. The same technique is used in other areas, such as aerospace chemistry, Radio astronomy, etc. The main objective of the CT is to reconstruct the internal part of an object without having to open it as a non-destructive test. To achieve this purpose, the CT uses the attention that X-rays undergo through this object with the information, the inner part of the object is reconstructed, that is to say the CT is an inverse problem.In this article uses the Fourier transform for the reconstruction of the internal part, for it is directly part of a continuous model, representing the density at the point (x, y) of a section, with a function p = p(x, y); and even though p is not required to be continuous, the Fourier method is more efficient and a better, more regular result is obtained p.
