Survival of and in Experimentally Infected Wild Boar Muscle Tissue under Freezing and Environmental Conditions.

Background: The aim of this study was to investigate the survival of and in decaying wild boar tissue and assess their freezing tolerance in experimentally infected animals.

Methods: The present study was conducted in Buenos Aires City, Argentina during the 2018-2019 period. Two wild boars were used, one infected with 20,000 muscle larvae (ML) of and the other with .

New records of Trichinella patagoniensis from Argentina.

Trichinella spiralis was long considered the sole Trichinella species in Argentina. However, since 2004, various Trichinella species, including the encapsulated Trichinella patagoniensis and Trichinella britovi, as well as the unencapsulated Trichinella pseudospiralis, have been detected in the country. The present study aimed to identify Trichinella ML at the species level from cougars naturally infected from Argentina.

Training with a psychosocial health neurolearning approach in Peruvian professionals with health insurance: Experimental study.

Introduction: Psychosocial risk factors as determinants of health at work can affect both the physical and psychological well-being of the worker. Training systems that include cognitive-preventive content work best when knowledge construction is based on neurolearning. The purpose of this study was to compare the degree of content processing with the insertion of deterrent (group A) versus persuasive sentences (group B) as an effect of a training with a neurolearning approach to psychosocial health in the work of a group of professionals with health insurance in the Peruvian Amazon.

Case Report and Literature Review of Insulinoma in the Geriatric Population: An 86-Year-Old Female with Syncope of Unknown Origin.

Insulinomas are extremely rare pancreatic endocrine tumors. The tumor is characterized by endogenous hypersecretion of insulin and ensuing development of symptoms of neuroglycopenia and the catecholaminergic response. Symptoms may not always be present, particularly in patients compensating appropriately with increased appetites and caloric intake due to low glucose levels.

Study of Trichinella patagoniensis in wild boars.

Trichinellosis is a zoonotic disease, which represents a significant public health concern in some South American countries, such as Argentina and Chile. Its impact is essentially due to absence of adequate control measures on meat from game animals, as well as the presence of illegal slaughterhouses and the trade of meat products without being tested for this parasite. In Argentina, trichinellosis is an endemic disease.

Congenital leukemia with leukemia cutis: a case report.

Congenital leukemia is a rare malignancy. Most of the neonatal cases reported have acute nonlymphoblastic leukemia. A number of chromosomal translocations and deletions have been found carrying an unfavorable prognosis.

Nitric oxide is involved in the response of the isolated intact and epithelium-denuded rat trachea to the β₂ adrenergic receptor agonist salbutamol.

Background: The involvement of the airway smooth muscle mediator nitric oxide (NO) in the actions of the β₂ agonist salbutamol (Sal), a well-known bronchodilator, is very poorly understood.

Objectives: To determine if endogenous NO release is a major factor in the Sal-induced relaxation of the carbachol- and electrical field-stimulated rat trachea and determine the role of the tracheal epithelium as the possible source of NO involved in these effects.

Methods: Isolated carbachol- or electric field-stimulated pre-contracted in vitro male Sprague Dawley rat tracheas (with epithelium intact or denuded) were relaxed with incremental or discrete concentrations of Sal in the presence and absence of the NO synthesis inhibitor L-NAME.

Blastomycosis: case report investigating a persistent pulmonary lesion in an immunocompromised patient.

Blastomycosis is a well known infection caused by Blastomyces dermatitidis. It appears usually as a mild and self-limited disease, but disseminated cases are seen, especially in immunocompromised patients. In organ transplant recipients, fungal infections play an important role and in some cases can be fatal, but blastomycosis is a rare and uncommon condition in this setting and specifically in renal transplant patients.

Adaptation of the Medical Research Council Dyspnea Scale and the Oxygen Cost Diagram for its use in Puerto Rico.

Introduction: Dyspnea is a common and disabling symptom for patients with chronic lung diseases. The Medical Research Council Dyspnea Scale (MRC) and the Oxygen Cost Diagram (OCD) are widely used instruments validated in English to measure breathlessness.

Objective: To translate and culturally adapt the MRC and the OCD for its use in Puerto Rico.

Rhabdoid tumor: an unusual pediatric brain tumor.

Rhabdoid tumors of the brain are rare with an invariable dismal prognosis despite treatment. This is the case of a 3 year old boy who presented lethargy, somnolence, nausea, vomiting, and headaches one week prior to hospitalization. A posterior fossa tumor with hydrocephalus was noted on a head computed tomography (CT) scan.

Evaluation of patient age as a risk assigment parameter in high risk acute lymphocytic leukemia.

Historically, age has been used as criteria for risk group assignment in patients with acute lymphocytic leukemia (ALL). The prognosis varies among different age groups. Differences in the biological characteristics of the leukemic clone and clinical findings at diagnosis are also used for risk assignment in ALL.

Architecture, elastic fiber, and collagen in the distal air portion of the lung of the 18-month-old rat.

Background: The increase in the distal air spaces which takes place with age is the only sufficiently documented datum for differentiation between the senile and the adult lung. There are other pulmonary components which may be modified as the lung enters the phase of old age, but they have not as yet been sufficiently studied. The purpose of this study is to make a morphometric comparison between the wall thickness of the distal air spaces, elastic fiber, and collagen in lungs of rats of between 5 and 18 months of age.

Methodological contributions for the morphometric study of the lung: approximation to the ideal sample size and quantification of collagen fiber.

Background: A morphometric study of the rat lung was done to determine the importance, within the precision of a morphometric study, of the sample size in relation to the quality of the image and to propose a method for the quantification of lung collagen fiber.

Methods: Sixty Wistar rats, divided into two age groups consisting of adult and old rats, were used. The left lungs were studied and processed for light microscopy.

Therapy for pediatric aplastic anemia; 7 years experience at the Puerto Rico Pediatric Oncology Program.

Nine pediatric patients with aplastic or hypoplastic anemia were seen at the Pediatric Hematology-Oncology service of the University of Puerto Rico, from 1980 to first trimester of 1987. Included were eight males and one female ranging from twenty months to sixteen 8/12 years (mean 13 years). Hematomas and fever were the most common complaints.

Training child welfare workers for cultural awareness: the culture simulator technique.

The Mexican-American Culture Simulator introduces a new, cost-effective method of training child welfare workers for cultural awareness. It was published in 1981 by the Worden School as a two-volume module containing 20 vignettes each [7]. The accompanying trainer's manual provides instruction for conducting modular training and a discussion guide that analyzes the values and practice implications in each vignette [8].

Scheuermann's kyphosis. Results of surgical treatment by posterior spine arthrodesis in twenty-two patients.

Twenty-two patients with Scheuermann's kyphosis were treated with correction, Harrington instrumentation (in twenty-one), and posterior spine fusion. This procedure relieved pain and corrected deformity in all patients but loss of correction of 5 degrees or more occurred in sixteen of the twenty-two patients, including all those whose initial kyphosis was greater than 70 degrees. The incidence of complications was so high that this procedure should ordinarily be performed only for disabling pain or spinal cord compression.
