Atypical Clinical Presentation of Monkeypox Complicated by Myopericarditis.

We present a case of monkeypox infection in a man presenting with genital and labial ulcers, followed by submandibular lymphadenopathy, fever, and constitutional symptoms. His course was complicated by myopericarditis and an ongoing pleomorphic skin eruption. Viral deoxyribonucleic acid was detected by polymerase chain reaction in skin swabs, nasopharyngeal swab, saliva, and semen.

Coristoma pancreático dentro de un divertículo duodenal: a propósito de un caso / Pancreatic Choristoma within a duodenal diverticulum, an accidental finding: apropos of a case

Resumen El coristoma pancreático, o páncreas heterotópico, es una condición rara en gastroenterología. Esta entidad consiste en el hallazgo de tejido pancreático aberrante, en alguna zona del tracto gastrointestinal, sin continuidad vascular o anatómica con el páncreas normal, es poco reportado y presenta sintomatología variable. Presentamos el caso de un individuo de 46 años con dolor abdominal a quien se le encontró mediante exámenes invasivos un divertículo duodenal, el cual al examen histopatológico e inmunohistoquímico mostró un coristoma pancreático.

Abstract Pancreatic choristoma, also called heterotopic pancreas is a rare condition in gastroenterology. This entity consists of the presence of aberrant pancreatic tissue in some other area of the gastrointestinal tract without vascular or anatomical continuity with the normal pancreas; it has been seldomly reported and it could exhibit variable symptomathology. We herein report the case of a 46-year-old male, who presented with abdominal pain and was found, through invasive examinations to have a pancreatic choristoma within a duodenal diverticulum. The diagnosis was made using histopathology and immune-histochemistry testing.

Kinesiología / Kinesiology

La kinesiología es una metodología holística e integradora. Con grandes aplicaciones en situaciones subclínicas y de liberación de estrés, resulta de gran ayuda complementaria en situaciones patológicas, dada la posibilidad de activar los mecanismos innatos de salud, por su capacidad para reducir el estrés. Es de gran eficacia, pues se aplica a través de los músculos de la propia persona y en el mismo momento, lo que nos aporta la información con lo que trabajamos. Además de resultar una excelente terapia, sus técnicas de corrección, por separado, pueden mejorar el estado energético y anímico, con lo que optimiza los recursos de las personas en cualquier situación

Kinesiology is a holistic and complete methodology. Having great applications in sub-clinical situations and to get rid of stress, kinesiology has proven to be of great help in pathological cases, given its possibility to activate innate health mechanisms and through its capacity to reduce stress, kinesiology is very effective, since it is applied by means of the interested person's own muscles and at the same moment when information professionals work with is received.

Phospholipids and oxophospholipids in atherosclerotic plaques at different stages of plaque development.

We identified and quantified the hydroperoxides, hydroxides, epoxides, isoprostanes, and core aldehydes of the major phospholipids as the main components of the oxophospholipids (a total of 5-25 pmol/micromol phosphatidylcholine) in a comparative study of human atheroma from selected stages of lesion development. The developmental stages examined included fatty streak, fibrous plaque, necrotic core, and calcified tissue. The lipid analyses were performed by normal-phase HPLC with on-line electrospray MS using conventional total lipid extracts. There was great variability in the proportions of the various oxidation products and a lack of a general trend. Specifically, the early oxidation products (hydroperoxides and epoxides) of the glycerophosphocholines were found at the advanced stages of the plaques in nearly the same relative abundance as the more advanced oxidation products (core aldehydes and acids). The anticipated linear accumulation of the more stable oxidation products with progressive development of the atherosclerotic plaque was not apparent. It is therefore suggested that lipid infiltration and/or local peroxidation is a continuous process characterized by the formation and destruction of both early and advanced products of lipid oxidation at all times. The process of lipid deposition appears to have been subject to both enzymatic and chemical modification of the normal tissue lipids. Clearly, the appearance of new and disproportionate old lipid species excludes randomness in any accumulation of oxidized LDL lipids in atheroma.

The endothelin system and its role in acute myocardial infarction.

Immediately after an acute myocardial infarction (AMI) or in models of ischemia-reperfusion injury, cardiac endothelin (ET) system is markedly activated, and plasma levels of ET are increased. In the heart, expression of the main components of the ET system (ET-1 peptide, both receptor subtypes ETA and ETB, though not endothelin converting enzyme) are increased both at the gene level and protein level, in the viable myocardium, and--even more substantially--in the necrotic area. Despite these conspicuous abnormalities, the role of ET in this setting remains unclear. In the absence of human data, most short-term studies in animals (in terms of hours to up to 8 days post-AMI) and in the reperfused ischemic heart, have found beneficial effects of ET receptor blockade on survival rate, incidence of arrhythmias, cardiac function, and morphology. In contrast, many studies in which a long-term ET inhibition was started immediately post-infarction and the late effects were examined in animals with ensuing chronic heart failure (14-100 days postinfarction), adverse effects were also observed, such as scar thinning, further ventricular dilation, or even a worse survival rate. It appears that the ET system plays a dual role during the early post-AMI period. At present, it is not clear whether the short-term beneficial effects or long-term adverse effects of ET receptor blockade would prevail. Acute use of short-acting ET receptor antagonists in patients with AMI complicated by an acute heart failure is an attractive possibility that also remains to be investigated.

Downregulation of eNOS mRNA expression by TNFalpha: identification and functional characterization of RNA-protein interactions in the 3'UTR.

OBJECTIVE: We have previously shown that downregulation of endothelial nitric oxide synthase (eNOS) expression by tumour necrosis factor-alpha (TNF alpha) resulted entirely from the marked destabilization of the eNOS mRNA. As the 3'-untranslated region (3'UTR) in many eukaryotic mRNA has been well documented to bind regulatory trans-factors in the control of transcript stability, we have examined protein binding to this region of the eNOS mRNA. A high degree of homology amongst human and bovine 3'UTR also suggests that important functional features that are conserved through evolution are present within this region. METHODS: RNA-protein interactions were studied in cross-linking assays, in which radiolabelled RNA encoding the human eNOS 3'UTR or selected sequences was incubated with cytoplasmic extracts of cultured human umbilical vein endothelial cells (HUVECs). Serial 5'- and 3'-truncated deletional mutations of the eNOS 3'UTR were generated to identify the specific binding sequences. eNOS mRNA expression in HUVECs was assessed by RT-PCR analysis. RESULTS: Using radiolabelled RNA encoding the entire 418-nucleotide 3'UTR, we have identified ribonucleoprotein complexes (RNPs) of approximate molecular weights of 53, 56 and 66 kDa in the endothelial extracts. The formation of the 53- and 56-kDa RNPs was upregulated by TNF alpha, while the formation of the 66-kDa RNP was downregulated. Formation of the 53-kDa RNP was favoured by RNA fragments that contained sequences from the proximal and distal portions of the 3'UTR, whereas the formation of the 66-kDa RNP was favoured by RNA fragments with the AU-rich distal end. RNA fragments containing a CU-rich 158-nucleotide sequence from the medial portion of the eNOS 3'UTR (designated M158) favoured the formation of the 56-kDa RNP. Adenoviral gene transfer and overexpression of M158 RNA, as a protein-binding decoy to prevent the formation of the 56-kDa RNP on the endogenous transcripts, attenuated the TNF alpha-induced downregulation of eNOS mRNA in cultured endothelial cells. CONCLUSION: Our results demonstrate that the regulation of eNOS expression involves the specific binding of cytoplasmic proteins to highly conserved elements along the 3'UTR, and the 56-kDa RNP represents a novel regulatory trans-factor in the destabilization of eNOS transcripts.

Effects of VasoCare therapy on the initiation and progression of atherosclerosis.

VasoCare therapy, which involves the administration of autologous blood following the ex vivo exposure to physico-chemical stressors, has been shown to modulate immune responses. Since immune mechanisms have been recognized to be pivotal in the pathogenesis of atherosclerosis, we hypothesized that VasoCare treatment would inhibit atherosclerosis in LDL-R (-/-) mice. Three groups of LDL-R (-/-) mice were studied: a control group that was fed normal chow (Group I) and no other treatment; a control group that received a high cholesterol (HC) diet for 8 weeks (group II) with sham saline injections; and a third group (III) that received HC diet for 8 weeks and VasoCare treatment initiated after four weeks of HC feeding. Atherosclerotic area (AA), relative to total aortic area (TA), was assessed after 8 weeks of HC feeding by oil red O staining, and cross sectional plaque area at the level of the aortic valve leaflets was determined by quantitative morphometry. HC mice exhibited substantial aortic lipid deposition which was profoundly reduced in the VasoCare treated animals (AA/TA ratios in group II: 0.32+/-0.15 vs. group III: 0.17+/-0.06; P<0.05). This was associated with a significant decrease in cross sectional area of plaque in the aortic sinuses. VasoCare therapy also reduced the xanthoma formation and limb swelling characteristic of this animal model. However, cholesterol levels, measured by an enzymatic assay, showed similar marked increases in total serum cholesterol (CHO) in the animals receiving HC diet alone and those receiving the HC diet and VasoCare treatment [group I: 5.4+/-0.8 mM, group II: 46.7+/-3.6 mM, and group III: 44.7+/-2.8 mM (P<0.01 vs. group I)]. We conclude that VasoCare treatment inhibits progression of atherosclerotic lesions in a murine model of human familial hypercholesterolemia by a mechanism independent of cholesterol lowering.
