THERAPEUTIC APPROACH OF COMPLICATED HYDATID DISEASE: ROLE OF ENDOSCOPIC RETROGRADE CHOLANGIOPANCREATOGRAPHY IN CHOLANGIOHYDATIDOSIS.

Background: Hydatid disease, a parasitic infestation caused by Echinococcus granulosus larvae, is an infectious disease endemic in different areas, such as India, Australia, and South America. The liver is well known as the organ most commonly affected by hydatid disease and may present a wide variety of complications such as hepatothoracic hydatid transit, cyst superinfection, intra-abdominal dissemination, and communication of the biliary cyst with extravasation of parasitic material into the bile duct, also called cholangiohydatidosis. Humans are considered an intermediate host, exposed to these larvae by hand-to-mouth contamination of the feces of infected dogs.

[Perception of the educational environment in residents of medical specialties in Chilean universities].

Background: The Learning Environment (LE) influences the performance of students, learning, social life, mental health, and the future of work.

Aim: To assess the learning environment (LE) among medical residents of 64 specialties.

Material And Methods: Two validated instruments "Postgraduate Hospital Education Environment Measure" (PHEEM) and "Ambulatory Care Learning Educational Environment" (ACLEEM), and open questions were answered online by 1259 residents from 15 universities.

Leukocyte and Platelet-Rich Fibrin Have Same Effect as Blood Clot in the 3-Dimensional Alveolar Ridge Preservation. A Split-Mouth Randomized Clinical Trial.

Purpose: Leukocyte- and platelet-rich fibrin (L-PRF) has been used for alveolar ridge preservation (ARP) in postextraction tooth sockets. However, current reports have measured its effectiveness in linear measurements of 3-dimensional ridge preservation. The purpose of this study was to determine the effectiveness of the use of L-PRF filling versus natural clot blood healing in ARP according to the clinical, radiographic, and volumetric measurements of postextraction tooth sockets.

Knobloch syndrome in a patient from Chile.

Knobloch Syndrome (KS) is a rare autosomal recessive hereditary disease. Despite its clinical heterogeneity, it is characterized by vitreoretinal degeneration and high myopia, with or without occipital skull defects. It is caused by mutations in the COL18A1 gene, which codifies for collagen XVIII, present in retina and vascular endothelium.

Cultured autologous bone marrow stem cells inhibit bony fusion in a rabbit model of posterolateral lumbar fusion with autologous bone graft.

Mesenchymal stem cells (MSCs) have been isolated from various tissues and expanded in culture. MSCs add osteogenic potential to ceramic scaffolds when used together. A spinal fusion rabbit model was used to evaluate whether a pellet of cultured, autologous bone marrow MSCs (BMSCs) with osteogenic differentiation could increase the fusion rate when co-grafted with an autologous bone graft compared to autograft alone.

Autograft versus allograft with or without demineralized bone matrix in posterolateral lumbar fusion in rabbits. Laboratory investigation.

Object: Posterolateral spinal fusions are performed to treat different spinal disorders. Autograft continues to be the gold standard; it is, however, associated with donor site morbidity and limited sources. Allograft has been used, but has been reported to result in lower fusion rates.

Iron deficiency anemia in infancy: long-lasting effects on auditory and visual system functioning.

Evoked potentials provide noninvasive measures of nerve transmission and CNS functioning. Auditory brainstem responses (ABR) and visual evoked potentials (VEP) show dramatic changes in infancy, largely as a result of progressive myelination. Because iron is required for normal myelination, pathway transmission in these sensory systems might be affected by early iron deficiency.
