Hemiplejía conversiva como accidente de trabajo. Consideraciones clínicas y legales
2011
Hysterical paralysis is a rare variant of conversion disorder. Its diagnostic can be difficult, and organic causes of paralysis must be ruled out. We report here a case of hysterical hemiplegia that was attributed to occupational-linked stress factors, and was consequently considered as an accident at work. Diagnostic and treatment procedures carried out in this case are reported. Compensation rates published by the Spanish Government pay little attention to occupational-linked psychiatric diseases. Frequently, as in our case, an extrapolation
Utility of post mortem MRI in definition of thrombus in aneurismatic coronary arteries due to incomplete Kawasaki Disease in infants
2016
Abstract Kawasaki disease (KD) is an acute, self-limited vasculitis of unknown etiology that primarily affects the coronary artery (CA) and presents in childhood. The characteristic coronary arterial lesion is an aneurysm, which may lead to thrombosis, dilatation, stenosis, and occlusion. Such an aneurysm is typically calcified and generally develops five or more years after the onset of acute KD. It becomes more noticeable after ten years. KD is sometimes difficult to diagnose because of the limited clinical features, especially in infants younger than 6 months old, where the clinical presentations often do not fulfill the diagnostic criteria for KD. We report a case of Incomplete Kawasaki…
Two-Step Digital Follow-up of Patients at High Risk for Melanoma: a Retrospective Analysis of 152 Patients
2021
Antecedentes: La dermatoscopia digitalizada (DD) ha demostrado mejorar la precisión en el diagnóstico del melanoma (MM) en pacientes de alto riesgo. La combinación de DD y fotografía corporal total (FCT) puede facilitar la detección de nuevas lesiones o la aparición de cambios macroscópicos precoces en lesiones previamente registradas. Objetivos: El objetivo del presente estudio fue determinar el número de biopsias necesarias para diagnosticar un MM y, las características clínicas y dermatoscópicas asociadas al diagnóstico de melanoma en pacientes en seguimiento, mediante DD y FCT, de lesiones pigmentadas. Pacientes y métodos: Se realizó un estudio retrospectivo de 152 pacientes con elevado…
Short- and long-term effects of vinblastine on the rat adrenal medulla
1979
The effects of a single high dose (10mg/kg) of vinblastine (vb) sulfate (“Velbe”, Lilly) on the ultrastructure, catecholamine (CA) content and activity of CA-synthesizing enzymes of the rat adrenal medulla were studied for up to 120h after intravenous injection of the drug.
p53 Involvement in the control of murine hair follicle regression.
2001
p53 is a transcription factor mediating a variety of biological responses including apoptotic cell death. p53 was recently shown to control apoptosis in the hair follicle induced by ionizing radiation and chemotherapy, but its role in the apoptosis-driven physiological hair follicle regression (catagen) remains to be elucidated. Here, we show that p53 protein is strongly expressed and co-localized with apoptotic markers in the regressing hair follicle compartments during catagen. In contrast to wild-type mice, p53 knockout mice show significant retardation of catagen accompanied by significant decrease in the number of apoptotic cells in the hair matrix. Furthermore, p53 null hair follicles…
The physiological impact of proinsulin C-peptide
1999
Abstract The proinsulin C-peptide fulfills an important function in the biosynthesis of insulin by facilitating the formation of the correct secondary and tertiary structure of the hormone. C-peptide and insulin are released in equimolar amounts to the circulation but C-peptide has generally been considered to be biologically inert. However, recent studies indicate that C-peptide administration to type 1 diabetes patients is accompanied by improved renal function, amelioration of autonomic dysfunction, stimulated tissue glucose utilization and augmented skin and muscle blood flow. The cellular mechanisms underlying these effects may be related to C-peptide's capacity to stimulate both Na + …
Handling and pathology reporting of specimens with carcinoma of the urinary bladder, ureter, and renal pelvis.
2003
Abstract Objective: Pathologists play a pivotal role in the diagnosis and in the report of the pathological features related to prognosis. Methods: To meet these endpoints, the following issues must be accomplished: adequate information about the patient history, proper handling of the specimens, identification of the reliable histopathological techniques necessary to reach the more detailed diagnostic information and evaluate the prognostic variables, and a standardized pathological report. Results: Recent efforts to standardize the histopathological evaluation have generated significant confusion among the urological and pathological communities as well. No consensus has been achieved abo…
The effect of L-thyroxine on the metamorphosis of Ascidia malaca
1981
Larvae of Ascidia malaca, both before and after hatching, were treated with L-thyroxine solutions. The effect of the thyroid hormone was to induce the onset of metamorphosis and then to cause the rate at which body reorganization occurred to increase. In treated larvae the resorption of the tail occurred only few hours after hatching, and a beating heart appeared form 10 to 15 h earlier than in the control larvae. These results are discussed in the context of a probable relationship between the occurrence of a hormonal metamorphic factor and the button cells of the trunk.
Pathology Reporting of Resected Pancreatic/Periampullary Cancer Specimen
2018
Pancreatic specimens have always been a great challenge for surgical pathologists due to their anatomic complexity and the difficulty of becoming familiar with these specimens. However, pancreatic specimens are becoming more and more common in many hospitals because of the improvements in surgical techniques and perioperative care that have dramatically reduced the postoperative mortality rate.
Death caused by a chain saw – homicide, suicide or accident?
1999
A 31-year-old farm worker was found dead beside a chain saw. Based on the testimony of a colleague and because of the situation at the site, the police very soon presupposed an accident. It was assumed that the victim had slipped on the sodden ground and had been killed by the subsequent swerving of the saw when starting the engine. The body presented with a deep lacerated wound at the right side of the nape of the neck, including the first cervical vertebra, the medullary canal and the right mandible as well as multiple fissures of the occipital bone, which were attributed to repeated forceful use of the chain by another person. A second wound with relatively sharp edges and a tangential f…
