    Full Text Available La pancreatitis autoinmune es una enfermedad recientemente caracterizada y que en la actualidad constituye un reto diagnóstico especialmente su diferenciación con el cáncer de páncreas. Su evolución a largo plazo es poco conocida, presentándose un caso estudiado a lo largo de 14 años y mostrando su evolución clínica, bioquímica y morfológica. Paciente mujer de 54 años que debuta con un cuadro de ictericia obstructiva y molestias abdominales inespecíficas y constatación en la TAC de un aumento de la cabeza del páncreas, todo ello sugestivo de neoplasia de páncreas. Fue intervenida evidenciándose un aumento difuso de todo el páncreas descartándose malignidad intraoperatoriamente, realizando únicamente colecistectomía y coledocoduodenostomía, quedando diagnosticada entonces como pancreatitis crónica. Durante los años posteriores fueron apareciendo diferentes procesos autoinmunes como asma, sialoadenitis y colangitis esclerosante secundaria, así como episodios recurrentes de ictericia e insuficiencia pancreática endocrina y exocrina. La aparición de estas complicaciones y la detección de niveles séricos elevados de IgG4 y de anticuerpos antianhidrasa carbónica II condujo a la reevaluación de la histología inicial concluyendo finalmente con el diagnóstico de pancreatitis autoinmune al evidenciarse una infiltración linfocitaria y plasmacitaria IgG4+, así como fibrosis y flebitis obliterativa. En los últimos años se ha añadido a las anteriores complicaciones una fibrosis retroperitoneal con hipertensión portal, varices esofágicas y esplenomegalia.Autoimmune pancreatitis is a recently characterized disease that still constitutes a diagnostic challenge, especially regarding differential diagnosis from neoplasia. Long-term outcome is poorly known. We herein report a case of a patient with autoimmune pancreatitis and 14 years of follow-up, and show its clinical, biochemical, and morphological characteristics.

    Full Text Available El pseudotumor inflamatorio de tráquea es poco frecuente y puede simular un tumor cuando se localiza en la luz traqueal o bronquial. El objetivo del presente artículo fue presentar un nuevo caso y revisar la literatura especializada. Se trató de una paciente de 23 años de edad, con cuadro de disnea de varios años de evolución, tratada con el diagnóstico de asma bronquial. Fue intervenida de urgencia por empeoramiento de la disnea y diagnóstico de tumor intratraqueal, según estudio broncoscópico. Se practicó la resección de 5 anillos traqueales con anastomosis término-terminal. La evolución posoperatoria fue satisfactoria y la paciente se encuentra libre de recidiva 5 años después de la operación.The inflammatory tracheal pseudotumor is rare and it may mimic a tumor when it is located in the tracheal or bronchial light. The objective of this article was to present a new case and to review the specialized literature. The case of a 23-year-old patient with a picture of dyspnea of several years of evolution treated with diagnosis of bronchial asthma was reported. She underwent emergency surgery due the worsening of dypsnea and to the diagnosis of intratracheal tumor according to a bronchoscopic study. The resection of 5 tracheal rings was performed with termino-terminal anastomosis. The postoperative evolution was satisfactory and the patient has been free of relapse five years after the operation.

    Knowledge of Pseudotumor cerebri syndrome is sparse. There are common features but varying etiologies causing an increase in intracranial pressure. Idiopathic Intracranial Hypertension - mostly affecting young obese women - is a syndrome of unknown origin in which neuroimaging can depict consequences of increased pressure. On the other hand, a wide array of pathologies can cause (or attribute to) an increase in intracranial pressure (Secondary Intracranial Hypertension), some of which can be depicted by neuroimaging. Special attention should be payed to abnormalities of the intracranial venous sinuses. Although their role still remains to be elucidated one should be aware of common features on venography.

    Full Text Available Orbital pseudotumor is a benign disease involving the orbital structures. Pseudotumor of the ciliary body is rare. We present a case of a 27-year-old male who presented with gradual visual loss, pain, and redness in his left eye. On examination he was found to have a yellowish white mass at the periphery of anterior chamber in his left eye and ultrasound biomicroscopy (UBM revealed a ciliary body mass in the same eye. He was treated with systemic steroids, which was tapered over a period of 8 weeks. His symptoms improved and the ciliary body mass disappeared with no recurrence over the next 6 months. UBM is an important diagnostic tool for diagnosing ciliary body mass. Early diagnosis and prompt treatment with systemic steroids may help resolve pseudotumor of the ciliary body.

    1985-01-01

    A 60 year-old woman with a scalp epithelioma underwent radiotherapy, the dose being 57 Gray. A first epileptic seizure occurred twenty months later. Neurological examination revealed signs of left hemisphere involvement. γEG, angiography, CT scans, demonstrated a pseudotumoral avascular process. On account of the localisation, the patient being right-handed, no surgical procedure was performed. In spite of corticotherapy and anticonvulsive treatment, seizures recurred and neurological signs slowly progressed. The patient died, 22 months after the first seizure, of an associated disseminated carcinoma with cachexia. Neuropathological examination showed a massive lesion presenting all the features of delayed radionecrosis in the left hemisphere: situated mainly in the white matter; numerous vascular abnormalities; wide-spread demyelination; disappearance of oligoglial cells. The Authors recall the clinical and anatomical aspects of this condition for which the only successful treatment is surgical removal when location and size of the lesion permit. Finally, the mechanisms which have been proposed to explain this delayed cerebral radionecrosis are discussed [fr

    Of 259 hemophiliacs bone pseudotumors were diagnosed in 11 (4.3 %); they were localised in the femur (6 cases), calcaneus (4) and in the iliac bone (3). Two cases of combined fermoral and calcaneal lesions and 4 cases of bone fracture were observed. As a rule, pseudotumors developed in hemophiliacs with severe disease. An x-ray picture of a pseudotumor depended on its site and was characterized by a large soft tissue tumor shadow, often with calcinosis, and serious destructive changes in bones in the form or round foci of 7 cm in diameter with clear-cut contours. An adge defect of the cortical layer was defined in the diaphysis of the femoral bone (15 cm long). Destructive changes were often accompanied by osteosclerosis and periostitis

    Pseudotumors which are recognized by mammography as dense areas, can be classified by careful patient anamnesis and inspection of the organ. In most cases these lesions can be correlated with scars or tumorous changes of the skin. The socalled 'drawing-pin' phenomenon mainly is resulting from skin retraction by Cooper's ligaments and secondly from immediate invasion of the tumor. In all these cases short time radiographic follow-up examinations are recommended instead of surgery. (orig.) [de

    Intraosseous pseudotumor (i.e. chronic, encapsulated, hemorrhagic fluid collection that can be seen in any portion of the tubular bones) is an uncommon complication of severe hemophilia; however, it can occur with other rare bleeding disorders. We present the case of an 11-year-old girl with hypofibrinogenemia who had multiple intramedullary lesions that were consistent with intramedullary pseudotumor associated with this rare bleeding disorder. Percutaneous biopsy of a pseudotumor is contraindicated due to the high prevalence of complications, including life-threatening bleeding. Therefore, radiologists should make the diagnosis with characteristic MR imaging findings in a patient with a severe coagulation disorder. (orig.)

    We report a 61-year-old woman who was hospitalized because of abdominal pain in the right upper quadrant related to a liver tumor (ultrasound and tomographic findings). A collection of blood was obtained by a biopsy and there were no tumor cells. With the suspicion of acute fascioliasis (liver stage), due to severe eosinophilia and recent travel to endemic area of Fasciola hepatica, arc II and ELISA Fas 2 we carried out and were positive. Parasitological stool examinations were negative. During hospitalization a hepatic subcapsular hematoma presented as a complication and the patient developed fever because of cholangiolitic microabscesses in the left hepatic lobe. Percutaneous drainage was performed and positive cultures of secretions were obtained She received antibiotic coverage with vancomycin and imipenem. Treatment for Fasciola hepatica was initiated with nitaxozanida but it was discontinued due to oral intolerance. Later, she received a single dose of 250 mg triclabendazole with clinical and laboratory improvement. We presented this case because it is an unusual pseudotumoral presentation in acute hepatic fascioliasis. This parasitic disease is an emerging zoonosis in Perú.

    To evaluate the CT features of inflammatory pseudotumor of the liver with histopathologic correlation. The CT features of 14 cases (ten patients) with pathologically proven inflammatory hepatic pseudotumor were retrospectively analyzed and correlated with resected and biopsy specimens. The size of lesions ranged between 2.0 and 7.0cm (mean, 3.7 cm); On unenhanced CT, the masses were seen as ill-defined hypodense lesions, while on contrast-enhanced CT they were heterogeneous and multiseptated, with enhancement of internal septa and peripheral wall (n=3D10). In four lesions, central low density and peripheral homogeneous enhancement were seen. On histopathological correlation, the central hypoattenuated area corresponded to chronic inflammatory cell infiltrates with foamy histiocytes, plasmacytes, and lymphocytes, while the hyperattenuated peripheral wall and internal septa represented dense fibrosis. In patients in whon CT shows a heterogeneous enhancing mass, inflammatory pseudotumor of the liver should be included in differential diagnosis

    Full Text Available Calcifying fibrous pseudotumor is an uncommon lesion and has recently been recognized as a distinctive fibrous lesion. Esophageal calcifying fibrous pseudotumor is extremely rare and, to the best of our knowledge, has never been reported before. A 54-year-old woman underwent upper gastrointestinal endoscopy and endoscopic ultrasound because of intermittent dysphagia. The results showed 1 isoechoic esophageal submucosal tumor over the deep mucosa and submucosal layers, with calcifications inside. The patient underwent tumor excision, and the diagnosis was confirmed by pathological features, with abundant collagen, calcification and inflammatory cell infiltration. She received regular follow-up at the clinic and no evidence of tumor recurrence was found.

    Full Text Available Objetivos: La "Hipótesis de la Higiene" postula sobre los efectos inmunomoduladores inducidos por agentes infecciosos en los seres humanos. El objetivo principal de este trabajo es indagar sobre las evidencias de esa hipótesis y sobre sus aplicaciones en el campo del tratamiento de las enfermedades autoinmunes, haciendo especial hincapié tanto en los mecanismos de acción en los que se basan estas aplicaciones como en los resultados reales obtenidos. Además analizará la posible evolución de estas terapias, especialmente a la sombra de las controversias éticas que surgen de la aplicación de estos tratamientos en relación a si es lícito causar una infección para curar otra patología, como es el caso que nos ocupa. Resultados: Actualmente existen resultados prometedores de ensayos clínicos sobre terapias helmínticas aplicadas al tratamiento de enfermedades autoinmunes como son la enfermedad de Crohn y la colitis ulcerosa, resumidos en el apartado de resultados de este artículo. Igualmente prometedora es la gran variedad de ensayos clínicos que actualmente están en curso sobre la aplicación de la terapia helmíntica al tratamiento de diversas patologías en las que está involucrado el sistema inmunológico, como son: asma, rinitis alérgica, artritis reumatoide, esclerosis múltiple, diabetes Mellitus tipo I, encefalomielitis autoinmune, obesidad, autismo, etc que han llevado a identificar cuáles son los parásitos indicados en el tratamiento de este amplio espectro de enfermedades. Sin embargo es necesario indicar que no todos los helmintos son inmunorreguladores y, por lo tanto útiles en el tratamiento de estas enfermedades y que, los que lo son, no son útiles en el tratamiento de todas las enfermedades de origen inmunológico sino que presentan una marcada especificidad. Es más, la utilidad de éstos presenta una variabilidad importante, no sólo dependiente de la enfermedad de origen inmunológico a tratar, sino tambi

    Objective: The present study was aimed at describing uncommon presentations of intraosseous hemophilic pseudotumor in imaging diagnosis. Materials and methods: Retrospective study evaluating five hemophilic pseudotumors in bones of two patients with hemophilia A. Imaging findings were consensually evaluated by two musculoskeletal radiologists. Plain radiography, computed tomography and magnetic resonance imaging studies were analyzed. Results: At contrast-enhanced computed tomography images, one of the lesions on the left thigh was visualized with heterogeneously enhanced solid areas. This finding was later confirmed by anatomopathological study. Another uncommon finding was the identification of a healthy bone portion interposed between two intraosseous pseudotumors in the humerus. And, finally, a femoral pseudotumor with extension towards soft tissues and transarticular extension, and consequential tibial and patellar involvement. Conclusion: The above described imaging findings are not frequently reported in cases of intraosseous pseudotumors in hemophilic patients. It is important that radiologists be aware of these more uncommon presentations of intraosseous pseudotumors. (author)

    Full Text Available Abstract Introduction Pseudotumor cerebri is an entity characterized by elevated intracranial pressure with normal cerebrospinal fluid and no structural abnormalities detected on brain MRI scans. Common secondary causes include endocrine pathologies. Hyperthyroidism is very rarely associated and only three case reports have been published so far. Case presentation We report the case of a 31-year-old Luso-African woman with clinical symptoms and laboratory confirmation of Graves' disease that presented as pseudotumor cerebri. Conclusion This is a rare form of presentation of Graves' disease and a rare cause of pseudotumor cerebri. It should be remembered that hyperthyroidism is a potential cause of pseudotumor cerebri.

    Full Text Available El corazón endocrino, a través de sus hormonas polipéptidas atrial natriuretic factor (ANF o ANP y brain natriuretic peptide (BNP, contribuye a regular la precarga y la poscarga cardiacas. Otras importantes funciones se han descubierto recientemente incluyendo interacciones con el sistema inmunológico. Los niveles plasmáticos de BNP, no así los de ANF, aumentan durante un episodio de rechazo agudo del corazón alotransplantado pero retornan a niveles anteriores al episodio de rechazo después de un tratamiento exitoso del tal rechazo. Este fue el primer indicio que involucró el BNP y el sistema inmunológico. Otras patologías que tienen componentes inflamatorios también se ven acompañadas con cambios en la producción del BNP. El aumento del BNP tiene como base el aumento de la actividad transcripcional del gen inducida por citoquinas y substancias relacionadas. In vitro se puede demostrar que este aumento tiende a modular la actividad inmunológica. Inflamación y cambios hemodinámicos co-existen en la mayoría de las enfermedades cardiovasculares y por ende, es posible que sea beneficioso medir las dos hormonas como biomarcadores de cambios de volumen intravascular (ANF y de estos cambios más inflamación (BNP. Cambios en plasma de ANF relativamente más grandes que aquellos de BNP podrían indicar un deterioro hemodinámico, mientras que cambios importantes en BNP podrían ser indicativos de recrudecimiento del proceso inflamatorio.

    1987-01-01

    Fourteen patients (15 joints) developed a foreign body reaction to methylmethacrylate, polyethylene, or metal adjacent to a total joint implant, a condition we would like to term granulomatous pseudotumors. There were eight male and six female patients. Their average age was 61 years. The hip was involved in 14 joints (femoral component 11 times, acetabulum 7, and greater trochanter once). One patient presented with granulomatous pseudotumors of the knee. The principal findings included increasing pain and radiographic evidence of loosening occurring on average 2.7 years following the implant. This was followed by a characteristic and gradually developing radiographic pattern of discrete rounded lucencies. These developed into large ovoid lytic areas, destroying both methylmethacrylate and bone. Histologically, the appearances were characterized by histiocytic infiltration and the presence of multiple foreign body giant cells. Foreign material was identified in 9 of 11 cases. The pathogenesis is unknown but appears related to micromovement or loosening of the implant. (orig.)

Positron emission tomography (PET) using amyloid-tracers has also been suggested as a marker of damage in white matter lesions in multiple sclerosis due to the nonspecific uptake of these tracers in white matter. We present the case of a 59 year-old woman with a pathological-confirmed pseudotumoral multiple sclerosis, who was studied with the amyloid tracer 18 F-florbetaben. The patient had developed word-finding difficulties and right hemianopia twelve years ago. In that time, MRI showed a lesion on the left hemisphere with an infiltrating aspect in frontotemporal lobes. Brain biopsy showed demyelinating areas and inflammation. During the following years, two new clinical relapses occurred. 18 F-florbetaben PET showed lower uptake in the white matter lesion visualized in the CT and MRI images. Decreased tracer uptake was also observed in a larger area of the left hemisphere beyond the lesions observed on MRI or CT. White matter lesion volume on FLAIR was 44.2mL, and tracer uptake change between damaged white matter and normal appearing white matter was - 40.5%. Standardized uptake value was inferior in the pseudotumoral lesion than in the other white matter lesions. We report the findings of amyloid PET in a patient with pseudotumoral multiple sclerosis. This case provides further evidence on the role of amyloid PET in the assessment of white matter and demyelinating diseases. Copyright © 2017 Elsevier B.V. All rights reserved.

  12. Inflammatory demyelinating pseudotumor with hemorrhage masquerading high grade cerebral neoplasm

    Full Text Available Demyelinating pseudotumors are rare, benign, solitary intracranial space occupying lesions which masquerade cerebral neoplasms. Contrast MRI shows open ring enhancement which is fairly specific for this entity. Advanced MRI techniques like MR spectroscopy and magnetizing transfer techniques can help differentiating these lesions. NAA/Cr ratio is significantly elevated in central regions of demyelinating pseudotumors than in gliomas and other lesions. Presence of abundant foamy macrophages, lymphoid inflammatory infiltrates around blood vessels, sheets of gemistocytic astrocytes with well-developed processes, well defined border of the lesion absence of neovascularity and necrosis should help us diagnose demyelinating pseudotumor fairly confidently on histopathology.

    Objective: To describe open-ring enhancement sign on MRI of demyelinating pseudotumor. Methods: Contrast-enhanced MRI of histologically confirmed demyelinating pseudotumors (14 patients) and astrocytomas (21) was reviewed. Results: Of the 14 cases of demyelinating pseudotumor, open-ring enhancement pattern was observed in 6; closed ring enhancement in 2; nodular enhancement in 3; patchy enhancement in 1; slight enhancement in 1; and no enhancement in 1. Of the 21 cases of astrocytoma, there was complete ring or lace-like enhancement in 13, no contrast enhancement in 6, patchy enhancement in 2, and none with open-ring enhancement pattern. Conclusion: Open-ring enhancement is a valuable sign in differential diagnosis between demyelinating pseudotumor and astrocytoma. (authors)

    Full Text Available Pseudo-tumoral hepatic tuberculosis is rare. It is characterized by non-specific symptoms and radiological polymorphism. Diagnosis is problematic. This article presents three cases, each clinically different from each other, that illustrate how difficult diagnosis can be. The definitive diagnosis of pseudo-tumoral hepatic tuberculosis was reached on the basis of histological examination of surgical samples. Treatment of the disease based on appropriate anti-tubercular therapy generally gives a positive outcome.

    Paratesticular tumors are infrequent and most are benigns. This a case presentation of a patient aged 24 with a history of good health coming to our consultation by presence of a hard and painless 4 cm tumor in right scrotum with a 6 months course. Scrotal ultrasound (US) showed a well circumscribed heterogeneous lesion separate of epididymis and the testis. Fine needle aspiration biopsy (FNAB) was not possible by hardness of tumor. A inguinal surgery was performed and the total tumor exeresis using freezing biopsy negative of malignancy. Final histopathological report was: calcified fibrous pseudotumor of spermatic cord. Patient's course has been satisfactory. Significance of inguinal surgery was confirmed for the paratesticular tumor approach, even more when FNAB it is not conclusive for diagnosis.(author)

    To demonstrate a variety of MR imaging findings of orbital inflammatory pseudotumors with extraorbital extension. We retrospectively reviewed the MR features of five patients, who were diagnosed clinically and radiologically as having an orbital inflammatory pseudotumor with extraorbital extension. The types of orbital pseudotumors were a mass in the orbital apex (n=3), diffuse form (n=2), and myositis (n=1). The extraorbital extension of the orbital pseudotumor passed through the superior orbital fissure in all cases, through the inferior orbital fissure in two cases, and through the optic canal in one case. The orbital lesions extended into the following areas: the cavernous sinus (n=4), the middle cranial fossa (n=4), Meckel's cave (n=2), the petrous apex (n=2), the clivus (n=2), the pterygopalatine fossa and infratemporal fossa (n=2), the foramen rotundum (n=1), the paranasal sinus (n=1), and the infraobital foramen (n=1). On MR imaging, the lesions appeared as an isosignal intensity with gray matter on the T1-weighted images, as a low signal intensity on the T2-weighted images and showed a marked enhancement on the post-gadolinium-diethylene triamine pentaacetic acid (post-Gd-DTPA) T1-sequences. The symptoms of all of the patients improved when they were given high doses of steroids. Three of the five patients experienced a recurrence. MR imaging is useful for demonstrating the presence of a variety of extraorbital extensions of orbital inflammatory pseudotumors.

    Full Text Available Introduction: Orbital pseudotumor, also known as idiopathic orbital inflammatory syndrome (IOIS, is a benign, non- infective inflammatory condition of the orbit without identifiable local or systemic causes. The disease may mimics a variety of pathologic conditions. We pre-sent a case of pseudotumor observed in a patient admitted under the name of orbital celluli-ties. Case Report: A 26-year-old woman reffered to our hospital with the history of left ocular pain and headache 2 days before her visit.. Ophthalmological examination of the patient was normal except for the redness and lid edema, mild chemosis and conjunctival injection. Gen-eral assessment was normal but a low grade fever was observed. She was hospitalized as an orbital cellulitis patient. She was treated with intravenous antibiotics. On the third day , sud-denly diplopia, proptosis in her left eye and ocular pain in her right side appeared. MRI re-vealed bilateral enlargement of extraocular muscles. Diagnosis of orbital pseudotumor was made and the patient was treated with oral steroid.She responded promptly to the treatment. Antibiotics were discontinued and steroid was tapered in one month period under close fol-low up. Conclusion: The clinical features of orbital pseudotumor vary widely . Orbital pseudotumor and orbital cellulitis can occasionally demonstrate overlapping features.. Despite complete physical examination and appropriate imaging, sometimes correct diagnosis of the disease would be difficult (Sci J Hamadan Univ Med Sci 2013; 20 (3:256-259

    Full Text Available Introduction. Inflammatory pseudotumor is an uncommon entity, and its cardiac origin is exceedingly rare. Case History. A previously healthy 27-year-old man was found to have a systolic murmur during preemployment screening evaluation. A transthoracic echocardiogram revealed a 4 × 2.5 cm mass originating from the right ventricle (RV outflow tract extending into the aortic root. A computed tomography guided biopsy confirmed an IgG4-related inflammatory pseudotumor. Patient was started on oral prednisone with subsequent reduction in mass size. Conclusion. Cardiac inflammatory pseudotumors are markedly rare tumors that should be considered in the differential of intracardiac tumors which otherwise includes cardiac fibromas, myxomas, and sarcomas.

  4. Pseudotumor of the Hip due to Fungal Prosthetic Joint Infection

    Directory of Open Access Journals (Sweden)

    2013-01-01

    Full Text Available Pseudotumors associated with total hip arthroplasty have been associated with metal-on-metal and metal-on-polyethylene total hip arthroplasties due to a granulomatous foreign-body reaction to methyl methacrylate, polyethylene, or metal ion release, but they have not been related to prosthetic joint infections. In this paper, we report an unusual case of Candida albicans total hip arthroplasty infection, causing a large inflammatory pseudotumor of the hip joint. Fungal periprosthetic joint infections are a rare clinical entity and difficult to diagnose, and a pseudotumor may be part of their clinical presentation. They should be suspected in immunodeficient host patients when clinical symptoms of prosthetic joint infections are observed.

    Hypopituitarism associated with pituitary mass in childhood is most frequently the consequence of craniopharyngioma or Rathke's cleft cyst. We report a patient with an intrasellar pseudotumor associated with hypopituitarism, which led us to a misdiagnosis of intrasellar craniopharyngioma. After spontaneous involution of the mass, diagnosis was revised. DNA analysis showed a deletion in the Prophet of Pit-1 (PROP-1) gene, a pituitary transcription factor. It is important to recognize that a PROP-1 deletion can cause pituitary pseudotumor that can be mistaken for a craniopharyngioma or Rathke's pouch cyst.

    This study aimed to determine whether children's headache drawings can distinguish between pseudotumor cerebri and migraine. Headache features associated with pseudotumor cerebri (pseudotumor; idiopathic intracranial hypertension) are nonspecific and are difficult to distinguish clinically from migraines. Children's headache drawings have a high predictive value for migraine versus nonmigraine headaches. We hypothesized that drawings could help to differentiate pediatric headaches due to pseudotumor cerebri from those associated with migraines. Children aged six to 18 years old attending university hospital pediatric neurology clinics were asked to draw a picture of how their headache feels. From our database of children's headache drawings, pictures by children with clinically diagnosed pseudotumor were compared with migraine drawings. Headache drawings of 21 children (16 females) with pseudotumor were compared with those of 518 children with migraine. Pseudotumor drawings depicted a variety of symptoms including pounding pain (n = 11), pressure-like pain (n = 3), photophobia (3), dizziness (1), and recumbency (1). Severe pain indicators included hammers, bombs, anvil, and vise grip. Positive visual phenomena included scintillations, scotomata, or blurring (n = 8). Negative visual phenomena included field defects (n = 2). Pseudotumor drawings were similar to migraine drawings except that 6 of 21 pseudotumor drawings (28.6%) depicted diplopia (crossed eyes, double images), whereas only three of 518 migraine drawings (0.6%) depicted diplopia (P drawings than migraine drawings. In all other respects, headache drawings by children with pseudotumor cerebri were similar to those drawn by children with migraine. Copyright © 2017 Elsevier Inc. All rights reserved.

  10. A clinical case of pseudotumorous chronic parainfectious limbic encephalitis

    Directory of Open Access Journals (Sweden)

    N. A. Shnaider

    2014-01-01

    Full Text Available Parainfectous limbic encephalitis (PILE associated with viruses of the Herpesviridae family is one of the forms of chronic herpes encephalitis characterized by limbic system dysfunction and a prolonged course with frequent exacerbations. There are two types of the course of the disease: latent autoimmune limbic encephalitis (LE progressing to mesial temporal sclerosis and pseudotumorous granulomatous LE. The latter (inflammatory pseudotumor or granuloma is characterized by the formation of a polymorphic inflammatory infiltrate with the elements of fibrosis, necrosis, and a granulomatous reaction and by myofibroblast cells. This is a slowly growing benign pseudotumor that contains much more plasma cells than inflammatory ones. The diagnosis of pseudotumorous LE is difficult and requires the participation of a neurologist, an immunologist, an oncologist, and a neurosurgeon. Perfusion computed tomography, magnetic resonance imaging, and magnetic resonance spectroscopy give proof to the adequacy of the term inflammatory pseudotumor because it is histologically difficult to characterize the lesion as a tumor or inflammation. When a chronic lesion in the central nervous system is lately diagnosed, the prognosis of the disease may be poor and complicated by the development of resistant symptomatic focal epilepsy and emotional, volitional, and cognitive impairments. It was differentially diagnosed from brain tumors (astrocytic, oligodendroglial, and mixed gliomas, ependymal, neuronal, neuroglial, and embryonal tumors, meningiomas, cholesteatomas, dermoid cysts, teratomas, and cysts, other reactive and inflammatory processes (leukemic infiltrations, systemic lupus erythematosus, multiple sclerosis, encephalomyelitis, hypoparathyroidism, Addison's disease, vitamin A intoxication, and the long-term use of glucocorticoids and contraceptives. The authors describe a clinical case of the pseudotumorous course of chronic PILE in a 28-year-old woman

    The purpose of this study was to describe the prevalence and imaging appearance of radiation induced pseudotumors in patients following radiation therapy for extremity soft tissue sarcomas. We retrospectively reviewed the serial magnetic resonance (MR) images of 24 patients following radiation therapy for extremity soft tissue sarcomas. A total of 208 exams were reviewed (mean, 8.7 exams per patient) and included all available studies following the start of radiation therapy. Exams were analyzed for the identification of focal signal abnormalities within the surgical bed suggesting local tumor recurrence. Histopathologic correlation was available in nine patients suspected of having local tumor recurrence. Additional information recorded included patient demographics, tumor type and location, radiation type, and dose. The study group consisted of 12 men and 12 women, having an average age of 63 years (range, 39-88 years). Primary tumors were malignant fibrous histiocytoma (n = 13), leiomyosarcoma (n = 6), liposarcoma (n = 3), synovial sarcoma (n = 1), and extraskeletal chondrosarcoma (n = 1). All lesions were high-grade sarcomas, except for two myxoid liposarcomas. Average patient radiation dose was 5,658 cGy (range, 4,500-8,040 cGy). Average follow-up time was 63 months (range, 3-204 months). Focal signal abnormalities suggesting local recurrence were seen in nine (38%) patients. Three of the nine patients with these signal abnormalities were surgically proven to have radiation-induced pseudotumor. The pseudotumors developed between 11 and 61 months following the initiation of radiation therapy (mean, 38 months), with an average radiation dose of 5,527 cGy (range, 5,040-6,500 cGy). MR imaging demonstrated a relatively ill-defined ovoid focus of abnormal signal and intense heterogeneous enhancement with little or no associated mass effect. MR imaging of radiation-induced pseudotumor typically demonstrates a relatively ill-defined ovoid mass-like focus of intense

    2014-06-01

    Full Text Available La muerte celular programada y la fibrosis renal son procesos inherentes a la enfermedad renal crónica y, en tal sentido, ha sido recientemente descripta una clara desregulación de la maquinaria respiratoria mitocondrial en pacientes con enfermedad renal crónica asociada con un aumento del estrés oxidativo. Las células tubulares lesionadas vinculadas a los macrófagos intersticiales y miofibroblastos producen citoquinas y factores de crecimiento que promueven un estado inflamatorio, inducen la apoptosis de las células tubulares y facilitan la acumulación de matriz extracelular. La angiotensina II desempeña un papel central en la fibrogénesis renal y conduce a una rápida progresión de la enfermedad renal crónica. Los niveles crecientes de la angiotensina II inducen citoquinas pro-inflamatorias, la activación de NF-kB, moléculas de adhesión, quimiocinas, factores de crecimiento y estrés oxidativo. Toda la evidencia actual sugiere que la angiotensina II aumenta el estrés oxidativo mitocondrial, regula la inducción de apoptosis y condiciona al estado inflamatorio. Por lo tanto, existiría un papel determinante de las mitocondrias y el estrés oxidativo en el proceso inflamatorio renal. Finalmente, esta revisión resume nuestro actual conocimiento acerca de los posibles mecanismos que contribuirían con la apoptosis modulada por la inflamación y/o el estrés oxidativo durante la enfermedad renal crónica. Además, se propone un nuevo concepto de herramientas anti-inflamatorias que regulan el estrés oxidativo mitocondrial lo cual afectaría directamente al proceso inflamatorio y la apoptosis. Esta idea podría tener consecuencias atractivas sobre el tratamiento de patologías inflamatorias renales y de otras afines.

    Inflammatory pseudotumors are tumorations which can present themselves very aggressively in children. Three patients were studied as illustration. Each was diagnosed with inflammatory pseudotumors of the lung after surgical intervention and open lung biopsy, which each case being very different in terms of clinical and radiological manifestations and evolution. Basic Radiological procedures and CT were performed in all three cases and MR in two. While the results were not specific, they did provide some means for arriving at a diagnosis, the common trait among them being the manifestation of primarily aggressive behavior. In conclusion, although inflammatory pseudotumor of the lung general y presents itself as a solitary peripheral mass of benign character which generally evolves favorable after surgery, it sometimes behaves in a primarily aggressive way which could hinder, or render impossible, any forthcoming surgical intervention. Imaging techniques tend to provide findings which are varied and unspecific. In this regard, MR is more advantageous than CT for determining not only the relationship between the mass and its adjacent structures, but also for the detection and follow up of relapses.

    Inflammatory pseudotumor is a generic term used to designate a heterogeneous group of inflammatory mass-forming lesions histologically characterized by myofibroblastic proliferation with chronic inflammatory infiltrate. Inflammatory pseudotumor is multifactorial in etiology and generally benign, but it is often mistaken for malignancy given its aggressive appearance. It can occur throughout the body and is seen in all age groups. Inflammatory pseudotumor has been described in the literature by many organ-specific names, resulting in confusion. Recently within this generic category of inflammatory pseudotumor, inflammatory myofibroblastic tumor has emerged as a distinct entity and is now recognized as a fibroblastic/myofibroblastic neoplasm with intermediate biological potential and occurring mostly in children. We present interesting pediatric cases of inflammatory myofibroblastic tumors given this entity's tendency to occur in children. Familiarity and knowledge of the imaging features of inflammatory pseudotumor can help in making an accurate diagnosis, thereby avoiding unnecessary radical surgery. (orig.)

    Inflammatory pseudotumor, also known as inflammatory myofibroblastic tumor and plasma cell granuloma, is an uncommon low-grade lesion composed of spindle cells admixed with mature plasma cells and other inflammatory cells, such as histiocytes, lymphocytes, and eosinophils. Here, we describe the mammographic and ultrasonographic findings of a case of an inflammatory pseudotumor of the breast in a 60-year-old woman. With the suspicion of malignancy, core needle biopsy and surgical excision confirmed the mass as being an inflammatory pseudotumor of the breast.

    En la actualidad, aún existe controversia acerca de si los síndromes de sobreposición son entidades diferentes o la presencia de 2 enfermedades coexistentes. Deben ser buscados en los pacientes con hepatitis autoinmune que tienen datos de colestasis ya que sabemos que su comportamiento tiende a ser más agresivo con mayores tasas de cirrosis y necesidad de trasplante hepático así como pobre respuesta al tratamiento, el cual debe ser dirigido al fenotipo principal. Hacen falta definiciones estandarizadas que permitan su estudio en ensayos clínicos controlados.

    Purpose: To evaluate the clinical characteristics, diagnosis and operative treatment of pulmonary inflammatory pseudotumor (PIP). Method: The clinical data of 23 cases PIP were retrospectively analyzed. Results: Of all the cases, 10(43.4%) were correctly diagnosed as PIP, while 13 were misdiagnosed, among them 11(47.8%) as lung cancer, 1 as tuberculoma and 1 mediastinal tumour. Operative resections were carried out in all cases with 14 lobectomies, 1 segmental resection, 6 wedge-shaped resections and 2 enucleation of pseudo-tumors. All cases were recovered smoothly and discharged in good condition. Conclusion: It is difficult to differentiate PIP from lung cancer in respect of clinical symptoms and imaging manifestations. Fiberoptic bronchoscope examination and trans-skin puncture biopsy of lung lesion under X-CT guiding are important preoperative diagnostic measures. The proper kind of lung resection should be determined by preoperative or operative pathological biopsy diagnosis of lung lesion and excessive resection of normal lung tissues should be avoided

    Full Text Available Autoimmune hepatitis is a chronic, progressive disease, more frequent in women than in men, and of unknown etiology. Histologically, it is characterized by mononuclear cell infiltration in the portal tract, and biochemically by elevation of transaminases, hypergammaglobulinemia, and the presence of liver specific autoantibodies. Response to immunosuppressive treatment is generally good and the resolution of inflammation, both biochemically and histologically, is achieved in 87% of patients in 3 years after immunosuppressive treatment is started. Several studies have shown that in the absence of treatment the disease progresses rapidly to fibrosis, and the mortality rate is higher than 80% in the 5 years following diagnosis in untreated patients. Nevertheless, even if the patient has liver fibrosis, treatment decreases the inflammatory response and the histological progression of fibrosis. Life expectancy of patients who respond to treatment exceeds 90% at 10 years, and is 80% at 20 years; however, 10-15% of patients do not have satisfactory response to medical treatment. Standard treatment and new therapeutic options are reviewed in this article. La hepatitis autoinmune (HAI es una enfermedad crónica, progresiva, más frecuente en mujeres y de etiología desconocida, caracterizada histológicamente por infiltrado de células mononucleares en el tracto portal y bioquímicamente por hipertransaminasemia e hipergamaglobulinemia y por la presencia de autoanticuerpos específicos para el hígado. La respuesta al tratamiento inmunosupresor es generalmente buena y la resolución tanto bioquímica como histológica de la inflamación se logra en el 87% de los pacientes en tres años después de haber iniciado dicho tratamiento. Diversos estudios han demostrado que, en ausencia de tratamiento, la enfermedad lleva rápidamente a fibrosis y la tasa de mortalidad es mayor del 80% a los cinco años del diagnóstico.

    A 38-year-old man was admitted to our hospital with diplopia. The patient had a relatively well-defined pituitary mass with high cellularity as well as weaker enhancement on imaging modalities including computed tomography (CT) and magnetic resonance imaging (MRI), than a typical pituitary adenoma. The distinction between a pseudotumor and an invasive neoplasm is very difficult before biopsy. In this case report, we discuss the characteristic imaging features of a fibrosing inflammatory pseudotumor of the pituitary gland

Objetivo: el objetivo es evaluar las características de las hepatitis autoinmunes en la población infantil. Material y métodos: estudio retrospectivo de pacientes diagnosticados en nuestro servicio en los últimos 10 años. Las variables analizadas son: edad, sexo, forma de presentación, función hepática, inmunoglobulinas, autoinmunidad, histología, tratamiento, necesidad de trasplante y evolución clínica. Según la positividad de los auto-anticuerpos se clasifican en tipo I (ANA y/o ASMA y tipo II (LKM-1. Resultados: se diagnostica a siete pacientes, 5 mujeres (71,5% y 2 varones (28,5%; tipo I 5 y tipo II dos pacientes. La edad al diagnóstico es 21 meses a 12 años. En el tipo I la presentación clínica es como hepatitis aguda en 3 casos y 2 pacientes con insuficiencia hepática progresiva. Las tipo II se diagnostican tras un hallazgo analítico siendo asintomáticas. La elevación de transaminasas (x10 su valor se observa en el 71,5% e hipergammaglobulinemia en el 85%. El tratamiento instaurado es azatioprina y corticosteroides con un tiempo medio de remisión de 14 meses. Dos pacientes recaen al retirar corticosteroides. Conclusión: las formas de presentación son variadas y puede ser indistinguible a una hepatitis viral. Se debe sospechar ante una elevación de las aminotransferasas y la presencia de hipergammaglobulinemia. Con buenos resultados el tratamiento recomendado sería azatioprina y corticosteroides. Existen altos porcentajes de recaídas al retirar la corticoterapia por lo que algunos pacientes precisarían de dosis mínimas para mantener la remisión.Background: autoimmune hepatitis (AIH is an inflammatory disease of unknown origin that is responsible for progressive liver necrosis and ultimately cirrhosis.

    Erdheim-Chester disease (ECD) is a rare non-langerhans cell histiocytosis of unknown etiology. It is a multi-systematic xanthogranulomatous infiltration with almost constant bone involvement; the neurological manifestations are not specific and occur in 15-20% of cases. We report the case of a 59-year-old woman hospitalized for a frontal syndrome and right hemiparesis. Imaging revealed a left caudate nucleus process with recent infarct. Cardiovascular involvement and bilateral osteosclerosis of long bones strongly suggested ECD, confirmed after biopsies of the pericardium and bone. Pseudo-tumor encephalic ECD is very rare; the caudate nuclei is an unusual localization; ischemic stroke has been exceptionally described. Prognosis depends largely on the involvement of the central nervous and cardiovascular systems.

    Type 1 narcolepsy (NT1) is a chronic primary disorder of hypersomnolence characterized by excessive daytime sleepiness, cataplexy, sleep paralysis, hypnagogic hallucinations and disrupted nocturnal sleep. NT1 is linked to hypothalamic hypocretin deficiency, strongly associated with Human Leukocyte Antigen (HLA) marker DQB1*06:02 and of probable autoimmune origin. NT1 is usually associated with increased rates of overweight and obesity, and sometimes with increases in overnight blood pressure and increased rates of hypoventilation with raised CO 2 levels overnight. Many of these are predisposing factors for pseudotumor cerebri syndrome (PTCS). We present a case of a young girl with both NT1 and PTCS that responded well to treatment with acetazolamide after early identification, with improvement of headache and resolution of hypoventilation.

    Full Text Available El dolor es un síntoma de extraordinaria importancia en la práctica estomatológica y particularmente en lo concerniente a las alteraciones de la pulpa dentaria. Con el objetivo de profundizar en el conocimiento de las fases por las que atraviesa un proceso inflamatorio pulpar, que permiten predecir sus manifestaciones dolorosas, se realizó una revisión bibliográfica sobre el tema con un enfoque multidisciplinario y básico-clínico. Se utilizó el método documental para el análisis y tratamiento de la información ofrecida por las fuentes teóricas. El sitio en Internet Google fue empleado como fundamental motor de búsqueda y Lilacs, Hinari, Medline y PubMed fueron las bases de datos más revisadas. La clasificación del estado de inflamación pulpar, que atiende a eventos histopatológicos que no se pueden visualizar, resulta más difícil. Se podría lograr mayor precisión en un diagnóstico basado en el curso que sigue el dolor, de acuerdo a la magnitud del compromiso inflamatorio y apoyado en la rica semiología que se puede obtener si se sigue la trayectoria de las variables del estímulo nociceptivo. El incremento y profundización de los conocimientos en este campo contribuiyó significativamente a un mejor diagnóstico y tratamiento de los procesos inflamatorios pulpares.

    Sarcoidosis is a multisystemic inflammatory disease characterized by noncaseating granulomas in the affected organs. Its origin is unknown, although 1 case of familial transmission has been reported and there seems to be a close relation with altered helper T-cell response in the lung. Neurologic manifestations of sarcoidosis occur in 5%, of cases of systemic disease. Autopsies have shown central nervous system (CNS) involvement in as many as 16% of patients with systemic disease, and 1 study showed CNS involvement in 27% of patients. The most common presentation of neurosarcoidosis is cranial neuropathy, consisting typically of a seventh nerve palsy in 64% to 75% of cases. In fact, all the components of the nervous system and its envelopes, especially the basal meninges and midline structures, may be affected by the disease. The incidence of lesions involving the hypothalamic-pituitary gland complex is reported to be between 0.3% and 2.5%. The hypothalamus and the pituitary gland, among the endocrine glands, are by far the most frequently affects by sarcoid granulomas. However, intrasellar granulomas are rare, and isolated pseudotumoral neurosarcoidosis of the pituitary gland even more so. Here, we report a case that closely mimicks the appearance of a pituitary macro-adenoma. (author)

    To assess the spiral CT findings of inflammatory pseudotumor of the liver(IPTL), in order to distinguish this tumor from hepatocellular carcinoma, hepatic abscess or other space occupying liver lesions. The spiral CT findings of IPTL were retrospectively evaluated in six patients. All cases were confirmed by ultrasonography-guided gun biopsy. Four patients were men and two were women, and they were aged between 37 and 74 (mean, 49) years. The site, size, and number of IPTL were assessed, and their enhancement patterns were evaluated during the arterial, portal and delayed phases of spiral CT. Five cases involved a solitary mass and in one there were multiple masses with surrounding small nodules. Four cases occurred in the right lobe and two in the left lobe. Four of five surrounding nodules were in the left lobe. During the arterial phase of spiral CT scanning, three layers were separated from four of five cases of solitary mass;they were composed of central and peripheral portions of low attenuation, and an intermediate portion of isoattenuation. Delayed enhancement of the peripheral portion was prominent during the delayed phase. In the case involving multiple masses three layers were not seen during the arterial phase, but during the delayed phase enhancement was noted. The features of three layers, as seen on spiral CT, is considered to be very specific for distinguishing IPTL from other hepatic focal lesions.=20

    A fibro-osseous pseudotumor is a rare ossifying soft tissue lesion, which is thought to be a reactive rather than a neoplastic lesion, developing due to repeated trauma. The lesion mostly occurs in the subcutaneous tissue of the proximal phalanx of the digit and predominantly affects young adults, with a slight predominance in females. The clinicopathological features can mimic those of malignant soft tissue lesions, and diagnosis can be difficult. Less is known about the radiological appearance of the lesion, including magnetic resonance imaging (MRI) features, than about histological signs. Here, we report radiological findings, including MRI features, of a fibro-osseous pseudotumor of the digit in a young female

    Full Text Available Purpose: To describe visual loss at presentation in children with pseudotumor cerebri (PTC, and discuss mechanisms of visual loss and distinguishing features of pediatric PTC. Materials and Methods: Two children with papilledema and visual complaints were referred for ophthalmic evaluation. Both patients underwent a detailed ophthalmic work-up. Results: Patient 1, an 8-year-old girl, presented with a 2-week history of headache, vomiting, and visual impairment in both eyes. The child had no previous medical history. Patient 2, a 9-year-old boy, experienced sudden loss of vision in both eyes one week prior to presentation, along with severe headache and vomiting. He had undergone a renal transplantation one year back, and his current medications included cyclosporine A (CsA and oral prednisolone. Extensive disc swelling, lipid exudation and retinal thickening in the posterior pole were observed in both patients. Lumbar puncture in both showed elevated cerebrospinal fluid pressure. Both were treated with oral acetazolamide. Patient 1 additionally received intravenous methylprednisolone followed by an oral taper. CsA was stopped in patient 2. PTC and papilledema resolved with above measures in both patients, with partial recovery of visual function. Conclusions: PTC in children may have atypical manifestations. Visual acuity may be compromised acutely due to several factors. Patients with PTC and severe visual loss at presentation mandate an aggressive management approach. Use of intravenous steroids may be considered along with acetazolamide. Despite resolution of PTC, sequelae such as optic atrophy or macular scarring may impede eventual visual recovery. Physicians following patients on CsA need to be aware of the possible neuro-ophthalmic complications of the drug.

    Inflammatory pseudotumors of the lung are uncommon and etiologically diverse lesions that often present as solitary masses in the lung. It may be difficult to distinguish these lesions from more commonly encountered lung neoplasms. Inflammatory pseudotumors can also occur in other organs, but the lung is most commonly involved. The authors describe a 63-year-old male coal miner with a 40-year history of dust exposure, who had a large right middle lobe mass on chest roentgenograms, with slow growth over the 7 years prior to admission. Repeated transthoracic echo-guided biopsies of the mass were indicative of an inflammatory and reactive process. The radiographic, histologic, and clinical findings indicated a diagnosis of inflammatory pseudotumor. The patient refused surgical intervention and was regularly followed at the outpatient clinic. Follow-up chest roentgenograms for 1 year revealed that the tumor site was stable. This case suggested that inflammatory, pseudotumor, although uncommon, should be included in the differential diagnosis in a patient with pneumoconiosis and a solitary mass in the lung.

    Two male patients developed muscular pseudotumor of the breast following combined treatment of radiation and chemotherapy with cyclophosphamide, doxorubicin, methotrexate and procarbazine for oat cell carcinoma of the lung. The pathologic findings of the biopsy specimens revealed muscle and capillary changes similar to previously reported myocardiotoxicity from doxorubicin and radiation therapy. Discussed is a possible additive or synergistic toxic effect of doxorubicin and radiation therapy in the development of muscular pseudotumor of the breast

    Full Text Available Inflammatory pseudotumor (IP is a clinically aggressive but histologically benign condition of unknown cause. Its appearance in the temporal bone is uncommon. We present clinical, radiological, and histopathologic findings of three cases originating in the temporal bone. In the first case, a simultaneous IP of the temporal bone and parotid gland was found with histopathologic confirmation. In the second case, an enlarged cervical node, which was also believed to be related to IP, was observed accompanied with the temporal lesion. While the third case presented with chronic suppurative otitis media. Two of them were treated by surgery alone with complete resolve of the diseases. Another one underwent tympanomastoidectomy in combination with oral steroids, radiation, and chemotherapy, but the IP still recurred. A comprehensive review of the literature on clinical features of the temporal pseudotumor was conducted.

    Inflammatory pseudotumor is a non-neoplastic process of unknown etiology characterized by proliferation of connective tissue with an inflammatory infiltrate. IPT most frequently arises in the orbit, but can also be found in the larynx, the paranasal sinus and rarely in the skull base. We present the case of a 20-year-old patient with a 4-month history of headache and insomnia. Neurological examination showed limited head mobility and hypoglossal nerve dysfunction. The patient was afebrile and no abnormalities in blood tests were found. CT revealed the presence of a tumor mass destructing the right occipital condyle. MRI was performed and the mass was surgically removed. The histological diagnosis was non-specific chronic inflammatory granulation tissue. Inflammatory pseudotumors can often mimic malignant neoplasms, especially in cases where bone destruction is observed. IPT of the occipital condyle is a rare but aggressive lesion that should be treated by surgical excision. (author)

    Full Text Available Multiple sclerosis (MS is prominent among central nervous system diseases. It affects chiefly young people and almost inevitably results in disability. In the past decade, there has been an upward trend for the prevalence of MS worldwide; in particular, the higher prevalence of this disease has been registered in the Moscow Region, which is associated with both an objective increase in its morbidity and improvement of specialized care to the population in the region. MS is characterized by a variety of clinical manifestations. However, paroxysmal disturbances are referred to as the rare symptoms of MS: the incidence of epileptic seizures in this condition is 0.89 to 7.5% according to the literature data. In addition to the clinical form of MS, there are its rare malignant atypical forms that also include its pseudotumoral form characterized by intrinsic neuroimaging and clinical signs that are different from the classical form of MS and another abnormality of the central nervous system. The pseudotumoral form of MS is characterized by the development of acute focal demyelination that appears as a large focus of an increased magnetic resonance signal with perifocal edema as evidenced by magnetic resonance imaging. A pseudotumoral focus of demyelination can occur both at the onset of MS and during its recurrent course. The atypical onset of MS is a special challenge because of diagnostic problems, which may lead to erroneous therapeutic policy and have a negative impact on the late prognosis of the disease. The authors provide a clinical case of the pseudotumoral form of MS with convulsive seizures at the onset of demyelinating disease. The problems of diagnosis and therapeutic approaches are discussed.

    Inflammatory pseudotumor (IPT) of the liver is a rare pathologic lesion. Although IPTs within the liver shows spontaneous regression, these lesions are frequently misdiagnosed as malignant on the basis of the clinical manifestation and the results of diagnostic imaging. With special regard to magnetic resonance imaging (MRI), differential diagnosis such as hepatocellular or cholangiocellular carcinoma (HCC/CCC) as well as regenerative liver lesions are discussed in a case of IPT with concomitant hepatitis C virus (HCV) infection and congenital granulocytopenia.

    A case has been presented of a 72-year-old man on whom an excretory urogram showed the incidental findings of two soft tissue masses in the abdomen containing considerable deposits of calcium. The history was interesting in that the patient was classic hemophiliac with Factor VIII level less than 1%, who first developed symptoms and signs of multiple hemarthroses affecting the knees, ankles, elbows, and shoulders at the age of nine years. Secondary hemophilic arthropathy followed, particularly advanced in the right elbow. Total knee replacements were performed within the last 10 years. A mass within the muscles of the right chest wall, superficial to the ribs, was surgically removed. The abdominal masses in this case were studied with CT and showed considerable calcification with a fibrous wall. Surgical removal of pseudotumors is usually undertaken following diagnosis because the natural history includes continuous enlargement and destruction of the adjacent tissues. Because of the age of the patient and the significant cardiac history, it was considered inappropriate to undertake surgery for the masses in the abdomen which were considered presumptively to be pseudotumors. The clinical, radiological, and pathological aspects of pseudotumor of hemophilia were reviewed. In this case, besides the masses in the abdomen, hemophilic arthropathy of an elbow was illustrated and a soft tissue mass in the right chest wall was demonstrated radiologically and the pathological specimen shown after surgical excision.

    Malnutrition and overweight is a common problem in modern societies. Primary abdominal lipectomy is a standard surgical tool in patients with these problems. However, unknown secondary problems result from recent advances in obesity surgery. Plication of the anterior musculoaponeurotic wall is a widely and commonly used operative technique during abdominoplasty. Many different plication techniques have been published. So far no common standard and long-term effectiveness is proven. In addition, there is no sufficient literature dealing with the postoperative risks of plication of the musculoaponeurotic wall. Four patients with development of pseudotumors were reviewed. All four patients received 12 months in advance a primary abdominal lipectomy including a vertical plication of the musculoaponeurotic wall. All four patients were females with mean age of 61 years and mean body mass index (BMI) of 37 kg/m(2). All four patients had developed a pseudotumor of the abdomen as a long-term complication more than 12 months after primary abdominal lipectomy including a vertical plication of the anterior rectus sheath. One should be aware of the potential long-term risk of secondary postoperative hematoma formation, with or without partial necrosis of the anterior rectus sheath after vertical plication of the anterior musculoaponeurotic wall. Viewed clinically and radiologically, such sequelas may appear as pseudotumor like masses and require immediate revision.

    We report here on a case of intracranial inflammatory pseudotumor arising from the trigeminal nerve. A 52-year-old man presented with sudden onset severe headache. He had had facial numbness several months earlier and no signs indicating infection. On the computerized tomography scan, intracranial hemorrhage was detected at the cerebellopontine angle. Magnetic resonance imaging demonstrated a 2.7-cm-sized, homogenously enhancing mass. A provisional diagnosis of trigeminal schwannoma was made, and suboccipital craniotomy was then performed. The mass was encapsulated and had multiple capsular veins. There was a evidence of intratumoral bleeding. It originated from the trigeminal root and was adhered to the 4th cranial nerve. Pathologic examination showed fibrovascular tissue with dense infiltrates of plasma cells and lymphocytes, some histiocytes, and occasional neutrophils and eosinophils. It showed immunopositivity for leukocyte common antigen (LCA) and immunonegativity for S-100 and lysozyme. It was also immunopositive for EBV antigen. Intracranial inflammatory pseudotumors mostly arise from dural/meningeal structures in the intracranial location. This case is the first to describe an intracranial inflammatory pseudotumor originating from a cranial nerve. The pathologic examination supported the postinfection hypothesis out of several possible pathologic mechanisms.

    Full Text Available Metal-on-metal (MoM total hip arthroplasty (THA can be associated with adverse metal reactions, including pseudotumors. This case report describes a 58-year-old female with an MoM THA-related pseudotumor that caused unilateral leg edema from compression of her external iliac vein. After thorough preoperative workup to rule out infection and deep vein thrombosis and consultation with a vascular surgeon, the patient underwent revision THA and excision of her pseudotumor. She had complete resolution of her swelling at 4 years after surgery. Review of all available case reports for this rare complication revealed that almost all patients were female. All patients underwent revision THA, with resolution of their symptoms. Literature review demonstrates that women are disproportionally affected by complications associated with MoM THA. We recommend close monitoring of patients with MoM THA, particularly women, for development of adverse metal reactions.

Además, el aumento de PCR-as correlacionó positivamente con el IMC, r = 0.318, p = 0.042. La disminución de col-HDL, apoA1 y PON en los individuos con mayor estado inflamatorio explicaría, en parte, el aumento de riesgo cardiovascular de estos pacientes, dado los efectos antiinflamatorios de la apoA1 y antioxidantes de la PON.

  19. Treatment with hydroxyurea in thalassemia intermedia with paravertebral pseudotumors of extramedullary hematopoiesis.

    Excessive ineffective erythropoiesis in thalassemia intermedia may cause paravertebral pseudotumors of extramedullary hematopoiesis. Due to the proximity to the spinal canal, these paravertebral masses carry the risk of severe neurological damage. Treatment strategies include hypertransfusion, radiotherapy, and laminectomy. Hydroxyurea, stimulating fetal hemoglobin synthesis, may represent an alternative therapeutic approach. We report on a 26-year-old patient suffering from thalassemia intermedia with progressive anemia symptoms and presenting multiple intrathoracic paravertebral pseudotumors of extramedullary hematopoiesis. Hypertransfusion therapy and splenectomy were followed by regular transfusion (baseline hemoglobin 10 g/dl) and chelation with desferrioxamine. With this treatment, clinical symptoms disappeared, paravertebral hematopoietic masses did not progress, but severe hemosiderosis developed within a few years. Hydroxyurea therapy was initiated to increase the efficacy of erythropoiesis, thereby reducing the required transfusion volume but suppressing concomitantly further expansion of extramedullary hematopoiesis, and finally leading to a reduction of transfusional iron load. Treatment was started with 4 mg/kg per day and stepwise increased to 12.5 mg/kg per day. The fetal hemoglobin concentration increased from 4.5 to 5.5 g/dl after 1 year and to 9.9 g/dl after 2 years of treatment. The yearly transfusion volume was halved during the 1st year of treatment. At present, after 26 months of treatment, the patient has been transfusion-independent for 10 months. Serum ferritin levels decreased from 2844 to 1335 ng/ml. Size and shape of paravertebral hematopoietic pseudotumors remained stable. No side effects of hydroxyurea have been observed. In thalassemia intermedia patients with extramedullary hematopoiesis, hydroxyurea may lead to independence from regular transfusion therapy without further expansion of ectopic hematopoietic tissue.

Hoy en día es posible además aplicarlo en el tratamiento de enfermedades autoinmunes graves, como esclerosis múltiple, lupus eritematoso sistémico o esclerosis sistémica, resistentes a la terapia convencional. Estudios en modelos animales nos demuestran que la transferencia de células progenitoras hematopoyéticas podría revertir el proceso de autoinmunidad, un fenómeno que puede explicarse mediante diferentes mecanismos. El resultado de los estudios clínicos que se están llevando a cabo, así como también estudios en pacientes y modelos animales, ayudarán a determinar el rol que el transplante de células progenitoras hematopoyéticas puede jugar en el tratamiento de enfermedades autoinmunes.Transplantation of hematopoietic stem cells, which are capable of self renewal and reconstitution of all types of blood cells, can be a treatment for numerous potential lethal diseases, including leukemias and lymphomas. It may now be applicable for the treatment of severe autoimmune diseases, such as therapy-resistant multiple sclerosis, lupus and systemic sclerosis. Studies in animal models show that the transfer of hematopoietic stem cells can reverse autoimmunity. The outcome of ongoing clinical trials, as well as of studies in patients and animal models, will help to determine the role that stem-cell transplantation can play in the treatment of autoimmune diseases.

    2007-01-01

    Full Text Available Primary tumor or tumor-like lesions of the spleen are rare. Among them, vascular lesions are the most common. Vascular tumor of the spleen is different from the usual hemangioma of soft tissue because the vascular structure of the spleen is unique. Sclerosing angiomatoid nodular transformation (SANT is a recently described vascular lesion of the spleen. Grossly, it is a multinodular, well-circumscribed tumor containing a hypervascular core. Microscopically, it comprises three types of vessels, and each type recapitulates the immunohistochemical characteristics of the normal vascular elements of the splenic red pulp, i.e. capillaries, sinusoids, and small veins, respectively. Because of the rarity of this entity, its actual pathogenesis is still unknown. In this study, we report a case of SANT occurring in a 43-year-old woman, in whom there were also multiple calcifying fibrous pseudotumors (CFPTs in the abdominal cavity. Both SANT and CFPT are thought to be variants of inflammatory pseudotumor. Coexistence of these two rare entities in a patient has never been reported, and this fact suggests that there might be a common mechanism contributing to the formation of these two types of lesions.

    Background Prior studies have described a pseudocalculus appearance in the distal common bile duct as a normal variant at cholangiography. The objective of this study is to describe the occurrence of pseudotumor in the distal common bile duct at endoscopic retrograde cholangiopancreatography (ERCP). Methods Nine patients who underwent ERCP between May 2004 and July 2008 were identified as having a transient eccentric mural-based filling defect in the distal common bile duct. A single reader systematically reviewed all studies and recorded the imaging findings. Results The mean diameter of the filling defect was 9 mm (range, 5 to 11). Eight patients had resolution of the filling defect during the same ERCP or on a subsequent ERCP, and in 2 of these patients the inferior border of the filling defect was not well visualized. The other patient underwent surgical resection of a presumed tumor with no evidence of malignancy on surgical pathology. Conclusion An eccentric mural-based filling defect in the distal common bile duct can be artifactual in nature and may reflect transient contraction of the sphincter of Oddi. Recognition of this pseudotumor may help avoid unnecessary surgery. PMID:21724120

Over the last decade, however, pseudotumors around metal-on-polyethylene surfaces have become more prevalent. Our patient presented with increased volume of the left thigh 8 years after hip arthroplasty revision surgery. Two years before the arising of the tumor in the thigh, a nodule in the inguinal region was investigated to rule out a malignant neoplastic process, but the results were inconclusive. The main preoperative complaints were pain, functional limitation and marked reduction in the range of motion of the left hip. Plain radiographs showed loosening of acetabular and femoral, and a large mass between the muscle planes was revealed through magnetic resonance imaging of the left thigh. The surgical procedure consisted of resection of the lesion and removal of the components through lateral approach. In respect of total hip arthroplasty, pseudotumors are benign neoplasms in which the bearing surface consists of metal-on-metal, but they can also occur in different tribological pairs, as presented in this case.

    Full Text Available Pseudotumor cerebral (PC é uma síndrome, caracterizada pela presença de hipertensão intracraniana (HIC e sistema ventricular normal. Pacientes submetidos a transplante renal parecem ser mais suscetíveis a desenvolvê-la, devido à terapia com imunossupressores. Ciclosporina (CsA é uma causa rara de PC, pouco descrita na literatura e que deve ser lembrada no diagnóstico diferencial de HIC e papiledema nesses pacientes. Relatamos um caso de um menino de 10 anos, há três anos com enxerto renal, em uso crônico de micofenolato mofetil (MMF, CsA e baixas doses de prednisona que apresentou quadro de cefaleia, vômitos, diplopia e fotofobia. Fundoscopia revelou edema de papila bilateral. Exame do líquor (LCR e de imagem foram normais. Após exclusão de causas secundárias, foi feito diagnóstico de PC devido ao uso crônico de CsA, que, portanto, foi substituída por Sirolimus. O paciente apresentou melhora clínica progressiva, com resolução do papiledema após três mesesPseudotumor cerebri (PC is a syndrome characterized by the presence of intracranial hypertension (ICH and no alteration in the ventricular system. Renal transplanted patients seem more susceptible to develop it due to immunosuppressive therapy. Cyclosporin (CsA is a rare cause of PC, scarcely reported in the literature, and should be considered in the differential diagnosis of ICH and papilledema in those patients. We report the case of a 10-year-old boy, with a renal allograft for three years, on chronic use of mycophenolate mophetil (MMF, CsA, and low doses of prednisone. The patient presented with headache, vomiting, diplopia, and photophobia. Funduscopy showed bilateral papilledema. Cerebrospinal fluid analysis and imaging tests were normal. After excluding secondary causes, PC was diagnosed based on the chronic use of CsA, which was then replaced by sirolimus. After that, the patient progressively improved, and the papilledema resolved in three months

    Recent evidence suggests that olfaction is impaired in patients with pseudotumor cerebri (PTC). To measure suprathreshold olfactory function by using the University of Pennsylvania Smell Identification Test (UPSIT), assessing its usefulness for routine clinical use. Forty PTC patients underwent USPIT olfactory testing. Twenty-nine out of 40 (73%) PTC patients (36 women, 4 men; mean age 34 years) had reduced suprathreshold smell sensation according to UPSIT scores: 19 (47%) had mild microsmia, 9 (23%) had moderate microsmia, and one (3%) was classified as having severe microsmia. The mean UPSIT score of all patients was 32.4 (95% confidence interval 31.4-33.4). Multivariate regression analysis found that UPSIT scores were not related to disease activity, disease duration, initial intracranial pressure (ICP), or visual function. Many PTC patients have reduced suprathreshold olfactory dysfunction that can be discovered by UPSIT, a rapidly administered smell test, which is suitable for clinical office use.

    Full Text Available Inflammatory pseudotumors (IPT form a group of etiologically, histologically, and biologically heterogeneous tumefactive lesions that are histologically characterized by prominent inflammatory infiltrates. IPT has been described in various organs including the lungs, bladder, liver, spleen, heart, and others. It may mimic a malignant tumor clinically and radiologically. We report a case of a 26-year-old woman with an ALK1-negative IPT (7 cm in maximal diameter mainly located in the 12th right back muscles, surrounding a fractured rib. Histologically, the tumor consisted of an inflammatory infiltrate composed predominantly of diffusely distributed lymphoplasmacytic cells and stromal fibroblasts associated with focal obliterative phlebitis. Conservative steroid treatment resulted in complete remission and the patient remained disease-free for more than 1 year later. To our knowledge this is the first report of IPT involving the skeletal back muscle and complete resolution under corticosteroid treatment.

    Full Text Available IgG4-related disease (IgG4-RD encompasses a group of fibroinflammatory conditions recognized in recent times. The main clinical features include variable degrees of tissue fibrosis, tumorlike expansions, perivascular lymphocytic infiltration rich in IgG4-positive plasma cells, and elevated serum IgG4. A case has been reported of an elderly patient with an unexplained unilateral exophthalmia; biopsy was performed and revealed lymphocytic infiltration, suggesting IgG4-RD. High serum levels of IgG4, in association with a good response to steroid therapy and to the exclusion of other diagnoses, confirmed the hypothesis of orbital pseudotumor by IgG4-RD.

    Inflammatory pseudotumors (IPT) of the liver and intrahepatic bile ducts is a rare cause of obstructive jaundice and portal hypertension in the pediatric age group. Because it seems to have a better long-term outcome than many of the conditions with which it may be confused, it is important to recognize the radiologic and pathologic features of this rare lesion so that appropriate therapy may be instituted.

    Rapid weight gain in a malnourished child can be associated with suture diastasis in the pattern of pseudotumor cerebri; this has been previously reported in deprivational dwarfism and cystic fibrosis. In a child with pelvic rhabdomyosarcoma, skull radiographs and cranial computed tomographic (CT) scans were available prior to a period of rapid weight gain induced by hyperalimentation. Suture diastasis developed and repeat CT scans showed this to be accompanied by smaller ventricles.

    Purpose: intracranial hypertension can change the morphology of anatomical structures that are critical in the evaluation of pseudotumor syndromes. The purpose of our study was to establish the normal range of such markers of intracranial hypertension and to consider a dependency on sex, age and body-mass index (BMI). Materials and methods: 123 persons without signs or symptoms of intracranial hypertension (63 females, 60 males, 18 - 86 years old, mean 49.5 SD 17.8 years, mean BMI 25.3 SD 42) were prospectively enrolled and MRI was performed at 3T. A STIR sequence in the coronal plane was used to measure the width of the optic nerve, the perioptic fluid rim and the total optic nerve sheath diameter in 4 different locations behind the eyeball. The height and width of the pituitary and Meckel's cave were also measured and the area was calculated. Results: the mean width of the optic nerve sheath narrows significantly from anterior (mean 5.3 SD 0.6 mm) to posterior (mean 4.1 SD 0.4 mm), as does the perioptic fluid rim (mean 1.4 SD 0.3 mm vs. mean 1.0 SD 0.2 mm) and - to a lesser extent - the optic nerve itself (mean 2.4 SD 0.4 mm vs. mean 2 SD 0.3 mm, p = 0.000 for all). There was no statistically relevant correlation of the width of the optic nerve sheath with age. The coronal area of Meckel's cave was independent of sex, age or BMI (mean 39 SD 9.3 mm{sup 2}). The height of the pituitary differed little in women (mean 4.4 SD 0.9 mm) and men (mean 4.2 SD 0.8 mm), but we found a significant negative correlation with age in women only (r = -0.38, p = 0.01).

    Full Text Available Actinomycosis often manifests with abscesses in the cervicofacial region. Hepatic involvement occurs usually secondary to an intraabdominal infection. “Isolated or primary hepatic actinomycosis (PHA defines actinomycosis in which the source of infection cannot be demonstrated elsewhere. Herein, we aimed to highlight hepatic actinomycosis in the differential diagnosis of hepatic mass lesions, and also its occurrence even in patients without underlying risk factors. A 24-year-old man, who presented with epigastric and right-upper-quadrant abdominal pain, fever, weight loss, and had a tumor-like mass in the liver was admitted to our hospital. He had no predisposing risk factors or comorbidities. We reviewed all the cases with PHA, who had no predisposing risk factors, in English medical literature from 1993 to 2014. Actinomycotic hepatic pseudotumors should be considered in the differential diagnosis of solitary liver lesions even in patients without any predisposing factors. Multi-disciplinary approach is important in the diagnosis and management. J Microbiol Infect Dis 2015;5(2: 79-84

    The first reported case of facial paralysis due to an inflammatory pseudotumor (IPT) of the facial nerve as a complication of epidermal nevus syndrome (ENS) is herein presented. A 10-month-old female patient was diagnosed with ENS at 3 months of age. She was referred to us because of moderate left facial paralysis. Epidermal nevi of her left auricle extended deep into the external ear canal. Otoscopy revealed polypous nevi and cholesteatoma debris filling the left ear. Computed tomography showed a soft mass filling the ear canal, including the middle ear, and an enormously enlarged facial nerve. Surgical exploration revealed numerous polypous nevi, external ear cholesteatoma, and tumorous swelling of the facial nerve. The middle ear ossicles were completely lost. The facial paralysis was improved after decompression surgery, but recurred 5 months later. A second operation was conducted 10 months after the first. During this operation, facial nerve decompression was completed from the geniculate ganglion to near the stylomastoid foramen. Histological diagnosis of the facial nerve tumor was IPT probably caused by chronic external ear inflammation induced by epidermal nevi. The facial paralysis gradually improved to House-Blackmann grade III 5 years after the second operation. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

    Pseudotumors of the craniovertebral junction (PTCVJ) are observed in long-term hemodialysis (HD) patients. There are neither criteria for diagnosis nor guidelines for screening. We attempted to determine magnetic resonance imaging (MRI) findings that could be used to detect PTCVJ, to determine the prevalence of PTCVJ, and to evaluate whether destructive spondyloarthropathy (DSA) might be a yardstick for selection of patients for MRI examination for PTCVJ. MRI were examined in 19 DSA patients (8 males, 11 females, age 61.4 +/- 7.3 years, HD duration 17.0 +/- 4.4 years) and in 20 sex-, age-, and HD-duration-matched non-DSA patients (9 males, 11 females, age 57.5 +/- 6.6 years, HD duration 17.7 +/- 4.9 years). We evaluated MRI characteristics of PTCVJ according those which occur due to rheumatoid arthritis. PTCVJ were characterized as follows: disappearance of fat pads in the upper region (supradental PTCVJ), intensity change of the 'predental triangle' in the anterior region (predental PTCVJ), and thickening of cruciform ligaments (retrodental PTCVJ). The prevalence of PTCVJ among patients undergoing HD more than 10 years was high (26 out of 39; 66.7%). The prevalence of PTCVJ was not different between DSA and non-DSA groups. We verified that the above MRI findings might be helpful in the detection of PTCVJ. These findings were observed frequently and independently also in patients with DSA. Copyright 1999 S.

    Full Text Available The diversity of clinical presentations of primary progressive tuberculosis (TB and the difficulty in establishing the diagnosis of paucibacillary forms is the subject of painstaking research, as well as a cause of delay in therapy. We report the case of a 10-year-old black child who presented with chest pain and progressive widening of the upper mediastinum. Computerized tomography of the chest revealed multiple calcifications that were not identified with X-rays. Biopsy through mediastinoscopy was compatible with a diagnosis of tuberculosis. Despite exhaustive investigation that included direct examination, culture for mycobacteria and PCR (Polymerase Chain Reaction of tissue samples, the etiologic agent was not revealed. Tuberculin conversion was observed during the follow-up and resolution period of the lesion, after administration of isoniazid, rifampicin and pyrazinamide. The nodal pseudotumoral form of tuberculosis is rare in immunocompetent children and it may simulate neoplastic disease; therefore, it should be included in the list of differential diagnoses of masses located in the anterosuperior mediastinum.

    Inflammatory pseudotumor is a reactive process in which the etiology and pathogenesis are not well defined, that can be found in any location. The cases with central nervous system affection have been described in meninges, brain, choroid plexus and cranial and spinal nerves. Multicentric cases, synchronous and asynchronous have been described. A 45 years-old woman with a rheumatologic disease (a seronegative spondiloarthropathy) who developed an inflammatory pseudotumor in spleen, liver and abdominal lymph nodes in 1995, associated to fever of unknown origin, six years later she presented with an inflammatory pseudotumor of the meninges in the convexity of the right frontoparietal region, with fever, malaise, and increase of globular sedimentation rate, microcytic hypochromic anemia and thrombocytosis. The clinicopathologic features of this lesion are revised, including the different theories in regard to the etiology and pathogenesis, and the role of cytokines produced by inflammatory cells in the tumor.

    Introducción. La etapa posprandial se asocia con el incremento de marcadores relacionados con el riesgo cardiovascular, cuya intensidad depende del estado metabólico.Objetivo. Determinar el impacto de la ingestión de una comida rica en grasas saturadas sobre el perfil metabólico e inflamatorio y su relación con la obesidad abdominal.Materiales y métodos. Se hizo un ensayo clínico en 42 individuos (21 con obesidad abdominal). Se midieron, en sangre, la glucosa, la insulina, el perfil lipídico, la proteína C reactiva, los lipopolisacáridos y la interleucina 6, en ayunas y después de la ingestión.Resultados. Además de la obesidad, se registró la presencia de resistencia a la insulina y de niveles elevados de triacilglicéridos y proteína C reactiva en ayunas. Asimismo, se detectaron niveles posprandiales más elevados de glucosa, insulina y triacilglicéridos. La interleucina 6 disminuyó en el grupo de personas sin obesidad y los lipopolisacáridos aumentaron en ambos grupos.Conclusión. La ingestión de una comida rica en grasas saturadas produjo un mayor impacto en las variables glucémicas en el grupo con obesidad y, aunque afectó de forma similar los lípidos en ambos grupos, el incremento de triacilglicéridos fue mayor en presencia de una concentración basal elevada y promovió el aumento de lipopolisacáridos. El estado inflamatorio basal y posprandial afectó en mayor medida al grupo con obesidad. El momento posprandial reflejó el estado más frecuente de los individuos en un día normal y permitió evidenciar la capacidad de respuesta metabólica frente a la ingestión de alimentos, así como los estados tempranos de riesgo metabólico.

    Full Text Available La interacción constante del organismo humano con diferentes sustancias, que incluso en muchas ocasiones se consideran inofensivas, tiene un alto impacto sobre todos los sistemas, siendo el cardiovascular uno de los más afectados. Por lo tanto, es vital reconocer los mecanismos por los cuales estas sustancias ejercen su efecto tóxico sobre este sistema, bien sea afectando la estabilidad de membrana y la función contráctil o generando disfunción de organelos intracelulares y estrés oxidativo. Numerosos estudios han descubierto efectos lesivos de sustancias, como la clozapina y las catecolaminas, que han tenido amplio uso durante largos años. En la actualidad aún se realizan investigaciones que buscan esclarecer los mecanismos cardiotóxicos de medicamentos de formulación común, entre ellos antineoplásicos y anti-inflamatorios no esteroideos (AINE, así como de sustancias de uso habitual que causan adicción, tales como alcohol, cocaína y cocaetileno, su metabolito activo.

    A case of osseous tuberculosis has been presented in a young black man who was known to be an addict to cocaine. An osteolytic lesion involved the proximal end of the tibia, being eccentric and subarticular in location. The knee joint spaces were intact, suggesting that no obvious involvement of the cartilages was present. Thus, neoplastic lesions such as chondroblastoma and giant cell tumor were considered in the differential diagnosis of the lesion which appeared to be benign radiologically. The lesion proved to be tuberculous in nature, with intact knee joint cartilages. A diagnosis of tuberculous 'pseudotumor' might be used aptly. (orig./SHA).

    A previously healthy 72-year old woman was admitted with a chief complaint of gross hematuria and fecaluria for 4 months. On initial computed tomographic examination, a lobulated shaped intravesical protruding mass with adhesion to the sigmoid colon was identified. Under a clinical diagnosis of bladder cancer with vesicosigmoid fistula vs sigmoid colon cancer with vesicosigmoid fistula, a frozen section evaluation of the bladder mass was performed to determine the origin of the tumor. Because the frozen section diagnosis of the bladder mass was an inflammatory origin, a partial cystectomy with segmental resection of the adherent sigmoid colon was elected. The microscopic examination of the partial resection of the urinary bladder revealed suburothelial inflammatory mass lesion, involving the entire wall of bladder with extension to the sigmoid colon, which was composed of spindle cells without significant atypia admixed with many lymphocytes, plasma cells, and some scattered eosinophils. Chronic inflammation around nerve bundles, sclerotic fibrosis, and prominent lymphoid follicles with plasma cells were the main features of the mass. No urothelial dysplasia or malignancy was seen. An average of 57 plasma cells per 1 high-power field was immunoreactive for immunoglobulin (Ig) G4 with IgG4/IgG ratio of more than 40%, a diagnostic feature of IgG4-associated inflammatory pseudotumor (IPT), arising in the bladder with the secondary involvement of the sigmoid colon. Recent studies reported many IPTs associated with IgG4 in other locations; however, to the best of our knowledge, IgG4-associated IPT in the urinary bladder has not been reported. We describe herein the first case of IgG4-associated IPT, lymphoplasmacytic type in the urinary bladder. Copyright © 2013 Elsevier Inc. All rights reserved.

    Full Text Available Objective: Pseudotumor cerebri syndrome (PTCS is characterized by symptoms and signs of increased intracranial pressure without ventriculomegaly, intracranial tumor or mass. This study aimed to explore and analyze 34 patients with PTCS according to age, sex, symptoms of the disorder, cranial magnetic resonance images findings, etiology, and treatment. Materials and Methods: A total of 34 patients who were diagnosed as having PTCS and followed up between January 2011 and August 2016 by Dicle University Medical School Neurology Department were included in this study. PTCS was diagnosed in accordance with the modified Dandy criteria. Results: Thirty-four patients were identified as having PTCS. Twenty-one (91.2% had headache, 19 (55.9% had blurred vision, 6 (17.6% had diplopia, 2 (5.9% had vertigo, 1 (2.9% had tinnitus, and 1 (2.9% had numbness of the face. Twenty-seven patients were diagnosed as having idiopathic intracranial hypertension, 21 (61.8% had no etiologic factors. Six (17.6% patients were obese, one of whom had recently gained weight and another had polycystic ovary syndrome. Seven patients were thought to have secondary PTCS with the following etiologic factors: 2 (5.9% patients had Hashimoto’s thyroiditis, 1 (2.9% had a history of all-trans retinoic acid intake due to a malignancy, 1 (2.9% had choroid plexus granuloma, 2 (5.9% had sinus venous thrombosis, and 1 (2.9% had Familial Meditteranian Fever. Conclusion: Although PTCS was described many years ago, its physiopathology and exact treatment procedures are not clearly understood. The most important target of its treatment is to prevent loss of vision and improve symptoms. With a better understanding of its pathophysiology, effective treatment protocols will be developed

    Full Text Available Introduction. Esophageal fibrovascular polyps are rare, benign, intraluminal, submucosal tumor-like lesions, characterized by pedunculated masses which can demonstrate enormous growth. The most frequent symptoms are dysphagia, vomiting and weight loss. Fibrovascular polyps with long stalks can regurgitate into the airways and cause asphyxia. Esophageal inflammatory pseudotumor is extremely rare lesion accompanied with various systemic manifestations as fever, anemia and thrombocytosis. Case report. We presented a 29-year-old man complaining of a long-lasting fever and dysphagia. He was found to have huge pedunculated submucosal tumor of esophagus, surgically completely resected. Histopathological examination showed that this giant tumor, 24 x 9 x 6 cm, was a fibrovascular polyp. The postoperative course was uneventful. The preoperative fever, anemia and thrombocytosis disappeared and did not recur in the postoperative course. Conclusion. We reported a patient with giant esophageal pedunculated tumor with clinical manifestations of inflammatory pseudotumor and histopathological picture of fibrovascular polyp, that we have not found described in the literature before.

    Lower cranial nerve sheath tumors are relatively rare. Cases of schwannoma collision tumors have rarely been reported, with most of the reported cases describing schwannoma and meningioma collision tumors. We report a very rare case of a cerebellopontine angle collision tumor of the ninth cranial nerve schwannoma with an IgG4 plasma cell pseudotumor. IgG4 plasma cell pseudotumors comprise a group of diseases called IgG4-related diseases (IgG4-RDs). These diseases usually affect organs such as the pancreas and salivary gland. Few cases of nervous system IgG4-RDs have been reported. Under intraoperative microscopy, the tumor in our case did not appear different from usual cases of schwannoma, but histopathology showed significant infiltration of IgG4 plasma cells. IgG4-RDs have a distinctive histopathologic pattern; however, their pathophysiology remains unclear. Special attention must be paid to the diagnosis of such diseases because they mimic other diseases and can be missed. Copyright © 2017 Elsevier Inc. All rights reserved.

    One hundred twenty-five walleye pollock (Theragra chalcogramma) were collected from Auke Bay, Alaska (USA) in 1985 and examined for histologic evidence of disease-causing infectious agents in 1987. A Goussia sp.-like coccidium was found in the kidney tubules of 75% and an Eimeria sp.-like coccidium was found in the intestine of 18% of the fish examined. The kidney coccidium was associated with sloughing of the tubular epithelium, peritubular fibrosis and granuloma formation. The intestinal coccidium was associated with severe tissue displacement and inflammation. In addition, X-cell pseudotumors were observed in the pseudobranchs (4%), and the fungus Ichthyophonus sp. was observed in the kidney, intestine or brain of 2% of the pollock.

    The utility of examinations with /sup 197/HgCl/sub 2/ has been shown in the study of pseudo-tumoral pulmonary afflictions. The following points seem to be the most important. The real possibility of differential diagnosis between benign and malignant tumors if the uptake of radio-mercury is related to the volume of the lesion. The possibility of differential diagnosis between cancers and the after-effects of more inflammatory TBC and non-TBC processes (inactive tuberculomas, fibroses). In sub-acute and chronic inflammatory lesions, some indication is furnished by the behavior of the uptake ratio at 24 and 72 hours. The topographical definition of the tumoral lesion in the case where there are associated secondary phenomena (atelectasis, a small quantity of pleural effusion). Individualization of extrapulmonary metastases which are situated at the level of the brain and the thoracic skeleton. Evaluation of the modifications of proliferative activities of cancers during radiologic or medical treatment.

    Purpose: To retrospectively evaluate institutional outcomes for patients treated with modern radiation therapy (RT) for biopsied orbital pseudotumor (OP). Methods and Materials: Twenty patients (26 affected orbits) with OP were treated with RT between January 2002 and December 2011. All patients underwent biopsy with histopathologic exclusion of other disease processes. Sixteen patients (80%) were treated with intensity modulated RT, 3 (15%) with opposed lateral beams, and 1 (5%) with electrons. Median RT dose was 27 Gy (range 25.2-30.6 Gy). Response to RT was evaluated at 4 months post-RT. Partial response (PR) was defined as improvement in orbital symptoms without an increase in steroid dose. Complete response (CR) 1 and CR 2 were defined as complete resolution of orbital symptoms with reduction in steroid dose (CR 1) or complete tapering of steroids (CR 2). The median follow-up period was 18.6 months (range 4-81.6 months). Results: Seventeen patients (85%) demonstrated response to RT, with 7 (35%), 1 (5%), and 9 (45%) achieving a PR, CR 1, and CR 2, respectively. Of the 17 patients who had ≥PR at 4 months post-RT, 6 (35%) experienced recurrence of symptoms. Age (>46 years vs ≤46 years, P=.04) and clinical response to RT (CR 2 vs CR 1/PR, P=.05) were significantly associated with pseudotumor recurrence. Long-term complications were seen in 7 patients (35%), including 4 with cataract formation, 1 with chronic dry eye, 1 with enophthalmos, and 1 with keratopathy. Conclusions: RT is an effective treatment for improving symptoms and tapering steroids in patients with a biopsy supported diagnosis of OP. Older age and complete response to RT were associated with a significantly reduced probability of symptom recurrence. The observed late complications may be related to RT, chronic use of steroids/immunosuppressants, medical comorbidities, or combination of factors.

    Full Text Available A total of 305 ambulatory patients recruited at the Division of Endocrinology, Hospital de Clínicas, University of Buenos Aires, with autoimmune thyroid disease (AITD were studied to search for associations between autoimmune thyroid disease and presence of serum markers of autoimmune diabetes mellitus. Screening for markers of pancreatic beta-cell autoimmunity was performed by radioligand binding assays (RBA as follows: autoantibodies to glutamic acid decarboxylase (GADA and proinsulin (PAA were determined in all sera, whereas autoantibodies to protein tyrosine phosphatase (IA-2A and insulin (IAA were additionally measured in 200 sera randomly selected from the total collection. In addition, every GADA positive serum among the remaining 105 sera was systematically tested for the presence of IA-2A and IAA. In the cohort of 305 AITD patients 22 (7.2% were previously diagnosed as type 1, type 2 or insulin-requiring type 2 diabetics. Ten of these patients presented serum marker positivity specific for β-cell autoantigens and 12 were marker negative. On the other hand, considering the majority of non-diabetic AITD patients (n=283, β-cell marker positivity was detected in 17 individuals (6.0%. The prevalence of autoimmune diabetes markers was much higher in the studied population than in the general population utilized as a control group, and GADA was the most frequent marker.Se investigó la asociación entre enfermedad tiroidea autoinmune y la presencia de marcadores séricos de diabetes mellitus en 305 pacientes ambulatorios con enfermedad tiroidea autoinmune reclutados en la División Endocrinología.

    Pseudotumor cerebri syndrome (PTCS) is defined by the presence of elevated intracranial pressure (ICP) in the setting of normal brain parenchyma and cerebrospinal fluid (CSF). Headache, vision changes, and papilledema are common presenting features. Up to 10% of appropriately treated patients may experience permanent visual loss. The mechanism(s) underlying PTCS is unknown. PTCS occurs in association with a variety of conditions, including kidney disease, obesity, and adrenal insufficiency, suggesting endocrine and/or metabolic derangements may occur. Recent studies suggest that fluid and electrolyte balance in renal epithelia is regulated by a complex interaction of metabolic and hormonal factors; these cells share many of the same features as the choroid plexus cells in the central nervous system (CNS) responsible for regulation of CSF dynamics. Thus, we posit that similar factors may influence CSF dynamics in both types of fluid-sensitive tissues. Specifically, we hypothesize that, in patients with PTCS, mitochondrial metabolites (glutamate, succinate) and steroid hormones (cortisol, aldosterone) regulate CSF production and/or absorption. In this integrated mechanism review, we consider the clinical and molecular evidence for each metabolite and hormone in turn. We illustrate how related intracellular signaling cascades may converge in the choroid plexus, drawing on evidence from functionally similar tissues.

    A retro-odontoid pseudotumor that is not associated with rheumatoid arthritis or hemodialysis is clinically rare. The majority of surgeons select transoral resection as the surgical treatment, often followed by posterior fusion or posterior decompression and fusion. In contrast, some authors have reported success with simple decompression without posterior stabilization in cases where atlanto-axial instability (AAI) is either absent or minor. In this study, we have evaluated the clinical and radiographic outcomes of C1 laminectomy without fusion as the surgical treatment for patients with cervical myelopathy that is associated with a retro-odontoid pseudotumor. A retrospective chart review was conducted on 10 patients who underwent C1 laminectomy without fusion for cervical myelopathy associated with a retro-odontoid pseudotumor. The average follow-up time was 29 months. All cases were graded as Ranawat grade 3a or 3b. After surgery, myelopathy improved in all of the patients. In 2 patients, the atlas-dens interval increased in the flexed position; however, this did not result in any clinical problems. The size of the retro-odontoid mass (measured on magnetic resonance images at least 12 mo after surgery) decreased in 4 of the 10 cases. AAI progression and mass enlargement were our primary concerns for this surgical option; however, C1 laminectomy did not cause severe AAI progression, no patients showed serious mass enlargement, and all patients demonstrated neurological improvement. This surgical strategy is beneficial especially for elderly patients given the risks of other surgical options that use an anterior transoral approach or posterior fusion.

    The placenta is one of the most common gross pathology specimens encountered by surgical pathologists, yet primary tumors are exceptionally rare and even rarer are entities with the potential to mimic malignancy. There are many nonneoplasticmass forming lesions in the placenta that are important to be aware of as many of these can be associated with adverse outcomes in the mother and fetus. Also important are entities which may be observed microscopically in the placenta and potentially confused as a malignancy. Knowledge of these potential pitfalls is essential to avoid making an incorrect diagnosis and causing undue alarm. Copyright © 2016 Elsevier Inc. All rights reserved.

    The overlap of morphological feature and mean ADC value restricted clinical application of MRI in the differential diagnosis of orbital lymphoma and idiopathic orbital inflammatory pseudotumor (IOIP). In this paper, we aimed to retrospectively evaluate the combined diagnostic value of conventional magnetic resonance imaging (MRI) and whole-tumor histogram analysis of apparent diffusion coefficient (ADC) maps in the differentiation of the two lesions. In total, 18 patients with orbital lymphoma and 22 patients with IOIP were included, who underwent both conventional MRI and diffusion weighted imaging before treatment. Conventional MRI features and histogram parameters derived from ADC maps, including mean ADC (ADC mean ), median ADC (ADC median ), skewness, kurtosis, 10th, 25th, 75th and 90th percentiles of ADC (ADC 10 , ADC 25 , ADC 75 , ADC 90 ) were evaluated and compared between orbital lymphoma and IOIP. Multivariate logistic regression analysis was used to identify the most valuable variables for discriminating. Differential model was built upon the selected variables and receiver operating characteristic (ROC) analysis was also performed to determine the differential ability of the model. Multivariate logistic regression showed ADC 10 (P = 0.023) and involvement of orbit preseptal space (P = 0.029) were the most promising indexes in the discrimination of orbital lymphoma and IOIP. The logistic model defined by ADC 10 and involvement of orbit preseptal space was built, which achieved an AUC of 0.939, with sensitivity of 77.30% and specificity of 94.40%. Conventional MRI feature of involvement of orbit preseptal space and ADC histogram parameter of ADC 10 are valuable in differential diagnosis of orbital lymphoma and IOIP.

    Full Text Available In contrast to virtually all organ systems of the body, the central nervous system was until recently believed to be devoid of a lymphatic system. The demonstration of a complex system of paravascular channels formed by the endfeet of astroglial cells ultimately draining into the venous sinuses has radically changed this idea. The system is subsidized by the recirculation of cerebrospinal fluid (CSF through the brain parenchyma along paravascular spaces (PVSs and by exchanges with the interstitial fluid (IF.

This article hypothesizes that glymphatic dysfunction is a major pathogenetic mechanism underpinning idiopathic intracranial hypertension (IIH. The rationale for the hypothesis springs from MRI studies, which have shown many signs related to IIH without evidence of overproduction of CSF. We propose that diffuse retention of IF is a direct consequence of an imbalance of glymphatic flow. This imbalance, in turn, may result from an augmented flow from the arterial PVS into the IF, by impaired outflow of the IF into the paravenous spaces, or both. Our hypothesis is supported by the facts that (i visual loss, one of the main complications of IIH, is secondary to the impaired drainage of the optic nerve, a nerve richly surrounded by water channels and with a long extracranial course in its meningeal sheath; (ii there is a high association between IIH and obesity, a condition related to paravascular inflammation and lymphatic disturbance, and (iii glymphatic dysfunction has been related to the deposition of β-amyloid in Alzheimer’s disease. We conclude that the concept of glymphatic dysfunction provides a new perspective for understanding the pathophysiology of IIH; it may likewise entice the development of novel therapeutic approaches aiming at enhancing the flow between the CSF, the glymphatic system, and the dural sinuses.

    Full Text Available Se sabe que la diabetes mellitus es un síndrome heterogéneo que tiene como elemento común una hiperglucemia crónica, como consecuencia de una deficiencia de insulina o una insuficiente efectividad de su acción. Nos propusimos en este trabajo describir los aspectos más relevantes de la diabetes autoinmune del adulto (LADA y exponer el resultado de nuestra experiencia. Se considera que un sujeto la padece cuando es clasificado inicialmente como diabético tipo 2, el inicio es después de los 34 años, tiene generalmente peso corporal, normal o bajo y en un tiempo relativamente corto necesita tratamiento insulínico para lograr un buen control metabólico y presenta además una mayor asociación con la producción de anticuerpos antiislotes (ICA, antiglutámico descarboxilasa (AGAD65, microsomales tiroideos y antigástricos parietales, con una susceptibilidad genética por la presencia de haplotipos HLA-DR. Al momento del diagnóstico clínico puede presentar o no una insulinodeficiencia. Se ha demostrado que la insulinoterapia es el tratamiento ideal para los individuos con LADA, con el mismo se ha evidenciado una alta tasa de conversión negativa de los ICA con un incremento de los niveles de péptido C en el suero. Por el contrario, el tratamiento con sulfonilureas produce una persistencia de los ICA, los que probablemente sean responsables de una destrucción progresiva de las células b del páncreas. Por tanto, estas observaciones justifican la elección de la insulinoterapia desde el mismo momento del diagnóstico.It is known that diabetes mellitus is an heterogeneous syndrome that has as a common element a chronic hyperglycaemia resulting from an insulin deficiency or from an insufficient effectiveness of its action.

    Full Text Available São relatados 35 casos de pacientes com síndrome de hipertensão intra-craniana causada por processos inflamatórios crônicos do sistema nervoso central. Apesar da multiplicidade dos agentes etiológicos, a conduta neuro-cirúrgica para a solução da hipertensão intracraniana é semelhante nestes processos. Os pacientes foram divididos em dois grupos. O grupo 1 inclui 7 pacientes nos quais o quadro clínico e neuro-radiológico era de lesão expansiva intracerebral. Estes pacientes foram submetidos a cranotomia com exerese do processo expansivo: tratava-se de cisticercos múltiplos em 5 casos, tuberculoma em um e granuloma blastomicótico em outro. A mortalidade foi nula e não houve recidiva da hipertensão intracraniana. Nos pacientes do grupo 2 as lesões fundamentais são representadas pela ependimite granulosa e leptomeningite crônica das cisternas basais. Os quadros clínico e neuro-radiológico são de hidrocefalia com dilatação ventricular e frequentemente sem sintais neurológicos focais. O prognóstico nestes casos é mais grave devido quase sempre à progressão da doença. Nos 28 pacientes incluídos neste grupo o tratamento de escolha foi a derivação ventriculoatrial ou ventrículoperitonial. A mortalidade foi de 39,2%.

    We present the case of a middle-aged woman with antecedents of cholecystectomy and several episodes of resi-dual coledocolitiasis resolved endoscopically. She attended Emergency Services due to a new clinical picture of abdo-minal pain and alteration of hepatic enzymes. Image tests showed lesions that suggested hepatic abscesses without ruling out a malign origin. Given this doubt it was decided to carry out a thick needle biopsy obtaining a diagnosis of an inflammatory pseudotumour of the liver related to IgG4-related disease. This is an infrequent entity but must be taken into consideration because - unlike malign pathology, which is the main differential diagnosis - its behaviour is benign, with a good evolution with medical treatment. That is why a suitable diagnosis is vital to avoid aggressive, diagnostic-therapeutic procedures.

    Full Text Available La Proteína C Reactiva (PCR es una de las proteínas plasmáticas que aparecen en la fase aguda de la inflamación. La periodontitis se relaciona con niveles elevados de PCR en adul tos y con una reducción de la misma después de su tratamiento. La diabetes, por otro lado, es una enfermedad que compromete la respuesta tanto inflamatoria como reparativa del organismo y los tejidos periodontales son particularmente sensibles a su efecto. La PCR por lo tanto, puede ser útil en el diagnóstico y en la determinación de progresión de la enfermedad periodontal (EP. El objetivo del presente estudio fue evaluar los niveles de PCR en pacientes con EP y pacientes con EP y diabetes mellitus tipo 2 (DM2. Se incluyeron 60 sujetos distribuidos en 3 grupos: 15 pacientes con EP (Grupo 1, 15 pacientes con EP y DM2 (grupo 2 y 30 pacientes sistémicamente sanos (grupo 3. A cada uno de los participantes se les realizaron pruebas bioquímicas: Proteína C Re activa (NycoCard® PCR, HbA1c (NycoCard® y glucosa en sangre. Para el diagnóstico de la enfermedad periodontal se siguieron los parámetros del 5° Taller Europeo de Periodontología. Para evaluar las diferencias entre los grupos se usó la prueba de Kruskal Wallis. Se encontraron diferencias estadísticas significativas al comparar la concentración de PCR en los 3 grupos (p<0.01, siendo el grupo de pacientes sanos el que presentaba el menor promedio (4.88±0.08 y los mayores promedios para los grupos de EP (5 .95±2.23 y EP/DM2 (5.21±0.20. Además se encontraron diferencias significativas (p<0.01 en los tres grupos con respecto a la concentración hemoglobina, talla, IMC y PI. Los resultados indican que los niveles séricos de PCR se elevan en pacientes con EP y en pacientes con EP y DM2. Aunque se notó esta diferencia, existen diversos factores tanto locales como sistémicos que pueden potencialmente influir en los niveles de PCR y estos representan una limitación y dificultad al momento de interpretar las prueba s.

    L'amylose primitive médiastinale isolée est rare et de diagnostic difficile. Nous rapportons l'observation d'un patient âgé de 41 ans ayant présenté une dyspnée et des crachats hémoptoïques. A l'examen physique il n'avait pas d'hypotension orthostatique. Les aires ganglionnaires périphériques étaient libres. La tomodensitométrie thoracique a objectivé un magma d'adénopathies médiastinales réalisant une masse de 45 mm x 60 mm. L'examen anatomopathologique d'une biopsie ganglionnaire guidée par médiastinoscopie a conclut a une amylose médiastinale de type AL. Il n'avait pas d'autres localisations amyloïdes. Un myélome multiple a été éliminé. Le diagnostic d'amylose primitive médiastinale de type AL a été retenu. Le traitement s'est basé sur des cures de Melphalan-prednisone. La chirurgie était évitée vu le risque hémorragique élevé. L’évolution était marquée par l'amélioration de la dyspnée, la disparition de l'hémoptysie et la diminution de la taille de la masse ganglionnaire devenant 25 mm x 20 mm. PMID:26308913

    The CT scan findings of 4 cases of orbital tumor, in which transcranial orbital decompression was performed because of no improvement by medication, were reported. The first case was a 71-year-old female with exophthalmos, decreased vision and ocular movement disturbance of the left eye. CT scan demonstrated an abnormal high density area in the left retrobulbar region with a thickened medial rectal muscle. Specimens were taken from a thickened medial rectal muscle. The histological examination revealed angitis. The second case was a 38-year-old female with exophthalmos, blepharoptosis, chemosis, decreased vision and ocular movement disturbance of the left eye. CT scan showed exophthalmos of the left eye, but no focal abnormality. Specimens were taken from fatty tissue-in the left retrobulbar region. The histological examination revealed no abnormal inflammatory changes. The third case was a 37-year-old female with orbital pain, exophthalmos and ocular movement disturbance of the right eye. CT scan demonstrated a growing abnormal high density area in the right retrobulbar region. Specimens were taken from the abnormal tissue in the right retrobulbar region. The histological examination revealed inflammatory changes of muscle and nerve. The forth case was a 61-year-old male with diplopia and exophthalmos. CT scan demonstrated an abnormal high density area in the left retrobulbar region. Specimens were taken from an abnormal tissue in the left retrobulbar region lying against the lateral wall of the orbit. The histological examination revealed severe infiltrations with lymphocytes and plasma cells. Transcranial orbital decompression improved the exophthalmos and ocular movement in all cases. (author)

    Full Text Available The diagnosis of pancreatic masses represents a great challenger for imaging studies. However the occurrence of pancreatic masses have been reported more frequently in the last years due to advances in imaging diagnostic methods. During the last decade, the surgical approach of pancreatic masses was limited to an attempt of establishing histological diagnosis, staging and evaluation of resection of these masses. Recently, the approach and staging of pancreatic masses was facilitated by sophisticated methods of diagnosis, especially, ultrasound, dynamic computerized tomography, magnetic resonance imaging (/RM, angiography, endoscopic retrograde cholangiopancreatography (CPRE, endoscopic ultrasound, laparoscopy and biochemical tumors markers. The present paper reports a case of a pancreatic mass due to foreign body in which the imaging study helped to determine out this rare etiological agent that has not been previouly described in literature.

    The CT scan findings of 4 cases of orbital tumor, in which transcranial orbital decompression was performed because of no improvement by medication, were reported. The first case was a 71-year-old female with exophthalmos, decreased vision and ocular movement disturbance of the left eye. CT scan demonstrated an abnormal high density area in the left retrobulbar region with a thickened medial rectal muscle. Specimens were taken from a thickened medial rectal muscle. The histological examination revealed angitis. The second case was a 38-year-old female with exophthalmos, blepharoptosis, chemosis, decreased vision and ocular movement disturbance of the left eye. CT scan showed exophthalmos of the left eye, but no focal abnormality. Specimens were taken from fatty tissue in the left retrobulbar region. The histological examination revealed no abnormal inflammatory changes. The third case was a 37-year-old female with orbital pain, exophthalmos and ocular movement disturbance of the right eye. CT scan demonstrated a growing abnormal high density area in the right retrobulbar region. Specimens were taken from the abnormal tissue in the right retrobulbar region. The histological examination revealed inflammatory changes of muscle and nerve. The forth case was a 61-year-old male with diplopia and exophthalmos. CT scan demonstrated an abnormal high density area in the left retrobulbar region. Specimens were taken from an abnormal tissue in the left retrobulbar region lying against the lateral wall of the orbit. The histological examination revealed severe infiltrations with lymphocytes and plasma cells. Transcranial orbital decompression improved the exophthalmos and ocular movement in all cases.

    Full Text Available Introduction: The in situ immune response within skin biopsies from patients affected by autoimmune skin blistering diseases (ABDs is not well characterized. Aim: Based on the fact that the ABD immune response is considered an adaptive immune response, both an innate immune response and inflammation would be expected in these diseases. Our investigation investigates the presence of cyclo-oxygenase-2 (COX-2, since this enzyme is commonly involved in innate immune responses. Methods: We utilized immunohistochemistry (IHC to evaluate the presence of COX-2 in lesional skin biopsies of patients affected by ABDs. We tested 30 patients with endemic pemphigus foliaceus (EPF, 15 controls from the endemic area, and 15 biopsies from healthy controls from the USA. We also tested archival biopsies from patients with selected ABDs, including 20 patients with bullous pemphigoid, 20 with pemphigus vulgaris, 8 with pemphigus foliaceus and 12 with dermatitis herpetiformis. Results: Most ABD biopsies stained positive for COX-2 in the lesional blister and/or the dermal inflammatory infiltrate, accentuated in the upper neurovascular plexus. In BP and EPF, the COX-2 staining was also seen in the sweat glands. All controls were negative. Conclusions: We document that COX-2 is expressed in lesional skin of patients with ABDs.

    Full Text Available São relatados 35 casos de pacientes com síndrome de hipertensão intra-craniana causada por processos inflamatórios crônicos do sistema nervoso central. Apesar da multiplicidade dos agentes etiológicos, a conduta neuro-cirúrgica para a solução da hipertensão intracraniana é semelhante nestes processos. Os pacientes foram divididos em dois grupos. O grupo 1 inclui 7 pacientes nos quais o quadro clínico e neuro-radiológico era de lesão expansiva intracerebral. Estes pacientes foram submetidos a cranotomia com exerese do processo expansivo: tratava-se de cisticercos múltiplos em 5 casos, tuberculoma em um e granuloma blastomicótico em outro. A mortalidade foi nula e não houve recidiva da hipertensão intracraniana. Nos pacientes do grupo 2 as lesões fundamentais são representadas pela ependimite granulosa e leptomeningite crônica das cisternas basais. Os quadros clínico e neuro-radiológico são de hidrocefalia com dilatação ventricular e frequentemente sem sintais neurológicos focais. O prognóstico nestes casos é mais grave devido quase sempre à progressão da doença. Nos 28 pacientes incluídos neste grupo o tratamento de escolha foi a derivação ventriculoatrial ou ventrículoperitonial. A mortalidade foi de 39,2%.A study into the neurosurgical approach to thirty-five patients with increased intracranial pressure due to inflamatory diseases affecting the central nervous system and meninges is reported. The entities under consideration were found to have similar surgical aspects despite the heterogeneity of etiologic agents. As regards the surgical treatment, two groups of cases were recognized. Group 1 comprises 7 patientes with symptoms of a space-occupying lesion; in these patients craniotomies were perfomed with good results. Group 2 included the remainder 28 cases with acquired hydrocephalus. In this group differents methods for ventricular drainage were used, but ventriculo-auriculostomy and specially ventriculo-peritoneal shunts proved to give more gratifying results. Chemotherapy was administred when the etiologic agent was disclosed. Corticosteroids were institued to reduce inflammatory reations and cerebral edema. A review of the literature supported the practical classification and surgical techniques employed.

    The case of a ganglion cyst in the pulp of a fifth finger in an elderly woman initially mimicking a soft tissue tumor is described. Most typical sites of ganglion cysts are well documented at the wrist and in the vicinity of inter-phalangeal and metacarpo-phalangeal joints. In this case, ultrasonography (US) and magnetic resonance imaging (MRI) demonstrated a cystic lesion within the pulp of the fifth finger and indicated carpal osteoarthritis as the distant - and unexpected - origin of the lesion. The suggested diagnosis of ganglion cyst was confirmed by computed tomography arthrography (CT arthrography) of the wrist, which showed opacification of the cyst on delayed acquisitions after intra-articular injection into the mid-carpal joint, through the fifth flexor digitorum tendon sheath. The communications between the degenerative carpal joint, the radio-ulnar bursa, the fifth flexor digitorum tendon sheath and the pedicle of the cyst were well demonstrated. (orig.)

    Full Text Available Immunoglobulin G4 (IgG4-related disease (IgG4RD is a relatively recently recognized entity that is histopathologically characterized by an extensive infiltration of lymphocytes and IgG4-positive plasma cells with dense fibrosis. IgG4RD is now known to affect any organ system, and a few cases of gastrointestinal lesions have also been reported. However, solitary IgG4RD of the stomach is still very rare. Furthermore, as it can mimic malignant conditions, it is important to recognize this disease to avoid unnecessary surgery. Herein, we present a case of IgG4RD presenting as an isolated subepithelial mass in the stomach.

    Full Text Available La miocarditis de células gigantes es una enfermedad grave y poco frecuente, cuya etiología, posiblemente autoinmune, se caracteriza por la presencia de células gigantes multinucleadas con infiltrado inflamatorio y necrosis extensa en la biopsia endomiocárdica. Es común su asociación con taquicardias ventriculares y con alteraciones de la conducción aurículo-ventricular, lo cual se resuelve algunas veces con tratamiento inmunosupresor. Dada la complejidad del pronóstico de esta entidad, el papel de los dispositivos de resincronización después de la estabilización de la falla cardíaca, no está claro. Aquí se reporta un caso en el cual el implante de uno de estos dispositivos fue parte fundamental de la terapia y recuperación del paciente.Giant cell myocarditis is an infrequent and serious illness, possibly of autoimmune etiology, characterized by the presence of multinucleated giant cells with inflammatory infiltrate and extensive necrosis in the endomyocardial biopsy. Its association with ventricular tachycardia is common and alterations in atrioventricular conduction are frequently solved through immunosuppressive treatment. Given the generally complex prognosis of this entity, the role of the resynchronization devices after the heart failure stabilization, is unclear. We reported a case in which the implant of one of these devices was a fundamental part of the therapy and patient recovery.

    Full Text Available Con el objetivo de identificar las características clínicas y por resonancia magnética de las lesiones inflamatorias de la médula espinal, se realizó un estudio observacional descriptivo transversal, de 56 pacientes, atendidos en los hospitales provinciales de Santiago de Cuba “Dr. Juan Bruno Zayas Alfonso” y “Dr. Saturnino Lora”, durante el periodo comprendido entre enero de 2014 hasta junio de 2015. Las características clínicas de las lesiones inflamatorias de la médula espinal fueron la cuarta década de la vida y el sexo masculino (60,7%, con síntomas predominantes como el dolor, la paresia y la parestesia. Existió predominio de las mielitis compresiva e inflamatoria. Al explorar el grado de concordancia entre la clínica y el informe de la resonancia magnética se obtuvo un índice de Kappa de 0,35. El diagnóstico imagenológico más relevante fue la mielitis compresiva en correspondencia con el diagnóstico clínico, no obstante la investigación permitió determinar que la concordancia entre la clínica y el diagnóstico imagenológico por resonancia magnética en los estudios realizados a estos pacientes en el periodo de estudio fue débil.

    Full Text Available En la actualidad se ha mostrado interés en el empleo de la saliva para ser utilizada como una alternativa de diagnóstico, predicción y progresión de diversas enfermedades con relación a otros fluidos corporales. Los objetivos trazados para la realización de este trabajo fueron: correlacionar las concentraciones en saliva y sangre de IL-1, IL-6, TNF-a, sustancias reactivas al ácido tiobarbitúrico y O2- de niños y adolescentes sistémicamente sanos. Se realizó un estudio de corte transversal en 23 niños y adolescentes sanos, entre 4 y 17 años de edad. Se les realizaron evaluaciones clínicas para determinar las condiciones bucales y estudios inmunológicos con el propósito de identificar los niveles de citosinas, a través del ensayo inmunoenzimático indirecto, el O2- por método citoquímico y las sustancias reactivas al ácido tiobarbitúrico, a través del ensayo colorimétrico. Hubo diferencia significativa entre las muestras de saliva y las de sangre periférica respecto a las citosinas y sustancias reactivas al ácido tiobarbitúrico estudiadas. Los resultados fueron: IL-1 en sangre= 1,646 ± 0,13 pg/mL y de IL-1 en saliva= 552,36 ± 75,7 pg/mL; IL-6 en sangre= 3,506 ± 1,85 pg/mL, e IL-6 en saliva= 26,89 ± 9,97 pg/mL. Al analizar el TNF-a en sangre fue de 12,91 ± 3,05 pg/mL y en saliva= 43,56 ± 6,44 pg/mL, las sustancias reactivas al ácido tiobarbitúrico en sangre= 9,46 ± 3,26 nmol/mL y en saliva= 1,26 ± 0,03 nmol/mL. No se observó correlación estadísticamente significativa entre las muestras de sangre y saliva para los valores de IL-1, IL-6 y sustancias reactivas al ácido tiobarbitúrico. En cuanto al TNF-a se evidenció una correlación significativa, r s= 0,78. No se evidenciaron células positivas para el O2- en las muestras estudiadas. Los resultados del análisis de correlación obtenido entre las muestras salivales y séricas, no aportaron evidencias suficientes para sugerir que la saliva pueda ser utilizada como fluido corporal que permita sustituir la determinación sérica de IL-1, IL-6 y sustancias reactivas al ácido tiobarbitúrico. En cuanto al TNF-a se evidenció una correlación significativa, lo cual podría plantear la posible sustitución de muestras séricas por salivales.At present times, there is interest in the use of saliva as a diagnosis, prediction and progression alternative of different pathologies in relation to the body fluids.

    Full Text Available “Inflammatory pseudotumor” (IPT has infrequently been reported in the medical journals. A retrospective analysis was conducted among more than 2,000 bladder tumor cases from January 1999 to December 2012 looking for patients with IPT in the final diagnosis. Six patients were found with median tumor size of 3.5 cm (range: 3–8 cm; computed tomography and/or magnetic resonance imaging was used to diagnose the tumor. All patients had complete resection of the tumors. On a median follow-up of 6 years (range: 2–10 years, no recurrences for IPT have been observed in all patients. We concluded that IPT is a rare disease of the urinary bladder and should be regarded with a high degree of suspicion. Although an extensive workup may be needed for definite diagnosis, it is worth to avoid unnecessary chemoradiotherapy or radical surgeries.

    To review MR imaging of figure skaters and snowboarders presenting with painful soft-tissue swelling of the lateral supramalleolar region with a clinical provisional diagnosis of soft-tissue tumor. MR imaging was prospectively reviewed by two sub-specialized musculoskeletal radiologists. The findings were correlated with a second clinical review and examination of the shoe wear. The patients were four female athletes undergoing heavy training regimes, ranging in age between 16 and 25 years. Two patients were elite figure skaters, and two were professional snowboarders. Three patients had unilateral masses with pain, and one patient presented with bilateral clinical findings. MR imaging showed subcutaneous, focal soft-tissue masses of the supramalleolar region in five ankles at the same level above the ankle joint. MR imaging prompted a second clinical review and correlation with the shoe wear. The MR imaging findings correlated to the level of the shoe rim or shoe buckle in all patients, confirming the suspected MR imaging diagnosis of an impingement syndrome. All four sportswomen were training excessively, ignoring safety advice regarding training duration, timing of breaks, and shoe wear rotation. (orig.)

    An unusual case of meconium peritonitis is reported. A neonate presented with a huge multi-septate effusion in the peritoneal cavity in relation with a small bowel perforation. No calcification was visible. Such a presentation cannot be included in one of the classical types of meconium peritonitis. It could be due to a bowel perforation occurring immediately before birth and could therefore be related to a mixed fibro-adhesive and generalize form. (authors)

    Temporomandibular joint (TMJ) is a synovial joint that represents the junction of mandible with skull. TMJ and mastication muscles are affected by temporomandibular disorders (TMDs). During the last two decades the advances in imaging diagnostic of TMJ have greatly contributed to the assessment of the TMJ disorders. Labelled leukocytes with technetium- 99m hexamethyl propylene amine oxime ({sup 99m}Tc-HMPAO) represent an efficient method that generates images based in physiological and/or biochemical changes related to inflammation. The aim of this study was to investigate the potential usefulness of technetium-99m labelled leukocytes scintigraphy in the diagnosis of TMJ inflammatory process applying a rabbit TMJ arthritis model. Arthritis was induced unilaterally with an intra-articular injection of ovalbumin in left ATM. On the contra-lateral side, the same dose of saline was injected. After five days, leukocytes were labeled with HMPAO and {sup 99m}Tc-HMPAO TMJ scintigraphic images were made. After twelve days a computed tomography was realized. Scintigraphic images obtained five days after induction of TMJ inflammation showed the localization of inflammatory process. The results were expressed as cpm of activity found in left ATM and contra-lateral side. Significant differences of activity were found between inflamed articulation and contra-lateral side (P = 0,0073). In conclusion, the method of leukocytes labeled with {sup 99m}Tc showed to be sensitive in detection of inflammatory disorders of TMJ and can be of great value in early diagnostic of these disorders.

    Objective: the present study was aimed at identifying temporomandibular joint inflammatory processes employing technetium-99m hexamethyl propylene amine oxime (99mTc-HMPAO)-labeled autonomous leukocytes. Materials and methods: we have utilized an experimental model of arthritis induction in ten adult male New Zealand rabbits by means of ovalbumin intra-articular injection into each left temporomandibular joint. For control purposes, saline solution was injected. After leukocytes radiolabeling with 99mTc-HMPAO and injection into rabbits, scintigraphic images were obtained. Results: a higher 99mTc-HMPAO-leukocytes uptake was observed in left temporomandibular joint in comparison with the contralateral joint. Wilcoxon non-parametric test was applied for statistical analysis. There was a statistically significant difference between counts of radioactivity per minute in the inflamed joint and the contralateral one (p = 0.0073). Conclusion: the method employing 99mTc-HMPAO-labelled autologous leukocytes allows an early and accurate detection of inflammatory processes, contributing to the adoption of a therapeutic conduct for patients before structural alterations have occurred.

    Radioiodine uptake in the thyroid tissue, metastasis of differentiated thyroid cancer (DTC), and in other tissues, depends on the expression of sodium-iodide symporter (NIS). Vascular permeability, effusions, inflammation, and other mechanisms may also play a role in the accumulation of radioactive iodine. A 63-year-old woman underwent radioiodine therapy, as well as a post-therapy whole-body scan, as she was suspected of having lung metastasis from thyroid carcinoma. The scan not only showed uptake at the lung metastasis but also a faint diffuse bilateral uptake in the posterior thorax. On SPECT/CT this uptake was located in a known Elastofibroma Dorsi (ED) previously diagnosed by contrast CT and viewed in a FDG PET/CT. The radioiodine uptake in ED, especially if typical, is not a diagnostic problem in SPECT/CT study, but can be misleading in a study limited to a few planar images, particularly if the uptake occurs asymmetrically, or ED is located in a unsuspected area.

    Full Text Available Las encefalitis son procesos inflamatorios de diverso origen, entre las cuales se incluyen las autoinmunes. La identificación de anticuerpos contra el receptor N-metil-D-aspartato permitió la caracterización clínico-inmunológica de una entidad susceptible a tratamiento inmunomodulador. Descripta originalmente en mujeres jóvenes, asociada a teratoma de ovario, es hoy una entidad reconocida en niños aun en ausencia de tumores detectables. El objetivo del trabajo, realizado a través de la revisión de historias clínicas, fue describir las características clínicas, evolutivas y los hallazgos en estudios complementarios de once niños con diagnóstico confirmado de esta entidad a través de la identificación de los anticuerpos específicos. Todos debutaron con síntomas psiquiátricos, en nueve de ellos asociando a convulsiones, y dos a movimientos extrapiramidales. En su evolución, todos presentaron compromiso del lenguaje, nueve, síntomas autonómicos graves, en uno con hipoventilación y requerimientos de ARM. La RM de cerebro fue anormal en tres. Ocho tuvieron EEG con asimetría del voltaje y/o amplitud, tres de ellos presentaron espigas. En el LCR seis tuvieron pleocitosis y tres de siete bandas oligoclonales positivas. Cinco, serologías IgM para micoplasma. El aumento de CPK en coincidencia con antipsicóticos ocurrió en cinco. Con el tratamiento inmunomodulador, cinco tuvieron recuperación total, tres, alteraciones conductuales/cognitivas y uno déficits severo. Un paciente resolvió su cuadro clínico sin tratamiento. En ninguno se detectó tumor asociado. Concluimos que frente a un niño con encefalopatía aguda y clínica compatible con esta entidad, una vez descartada causa infecciosa, se debe comenzar tratamiento inmunomodulador precozmente, evitar la utilización de fármacos antipsicóticos y realizar la búsqueda de posibles tumores ocultos.

Las lesiones de las membranas mucosas son de color blanquecino y persisten durante años después que desaparecen las lesiones de la piel. El odontólogo la diagnostica con frecuencia por mostrar sus primeros síntomas y signos en la mucosa bucal. Se caracteriza por la aparición de un infiltrado inflamatorio en banda y degeneración vacuolizante de la capa basal del epitelio, hechos que hacen pensar en una reacción autoinmune celular como base del proceso. Dos fenómenos importantes se describen en la respuesta inmunitaria celular: la expresión de antígenos de histocompatibilidad leucocitaria (HLA-DR y la molécula de adhesión intercelular-1 (ICAM-1. Se han reportado casos de transformación maligna en el liquen plano eritematoso o erosivo. El pronóstico del liquen plano es satisfactorio, cura en un tiempo promedio de 2 a 6 meses, pero existen casos cuya evolución se hace crónica y permanece durante años. Se realizó esta revisión bibliográfica con el objetivo de actualizar sobre este tema a estudiantes, estomatólogos y médicos en nuestra provincia.Lichen planus is a skin and mucous disease that is relatively frequent. Mucous membrane lesions are white-coloured and persisted for years after the skin lesions have disappeared. The odontologist often diagnoses it because its first symptoms and signs occurred in the oral mucous membrane. It is characterized by a band inflammatory infiltrate and vacuolizing degeneration of the basal layer of epithelium, events that might indicate an autoimmune cell reaction as a basis of the process. Two important phenomena are described in the immune cell response: the leukocyte histocompatibility antigen expression (HLA-DR and intercellular adhesion molecule-1 (ICAM-1. There have been reported cases of malignant transformation in erythematous or erosive lichen planus. The prognosis of lichen planus is

    Full Text Available Se valoró la eficacia de los métodos de detección de anticuerpos humorales empleados en el Instituto Nacional de Endocrinología para el diagnóstico de TCA. Se estudió un grupo de 100 pacientes con bocio y la sospecha clínica de que padecieran de TCA. A cada uno se le realizó una biopsia con aguja fina (BAF, que se tomó como la regla de oro del diagnóstico, determinación de anticuerpos plasmáticos antitiroglobulina por el método del TRC y antimicrosomales (AMS, para hacer una validación estadística de ambos métodos; sensibilidad, especificidad, valor predictivo para casos positivos, valor predictivo para casos negativos y el índice general de eficacia diagnóstica. Se hallaron 70 pacientes con resultados positivos de TCA por la BAF y 30, negativos. La sensibilidad de ambos métodos de detección de anticuerpos humorales fue pobre (45,7 % para el AMS y 30 % para el TRC. Aún aplicados los dos al mismo paciente no sobrepasó del 60 %. La especificidad fue mucho mejor para ambos métodos (73,3 % para la AMS, 90 % para el TRC y 70 % para ambos métodos juntos. El valor predictivo para casos positivos fue bueno (80 % para AMS, 87,5 % para TRC y 82,3 % para los métodos de conjunto y el predictivo para casos negativos fue 36,3, 35,5 y 42,9 %, respectivamente. La eficacia general fue tan solo del 54 % para el TRC, 48 % para AMS y 63 % para ambos métodos de conjunto. Se concluyó que estos métodos son útiles para reafirmar el diagnóstico cuando resultan positivos, pero de poca utilidad para asegurar que no se trata de esta afección cuando resultan negativosThe effectiveness of the humoral antibody detection methods used in the diagnosis of chronic autoimmune thyroiditis (CAT in the National Institute of Endocrinology was assessed. A group of 100 patients with goitier and presenting with clinical suspicion of CAT was studied. A fine needle biopsy was performed on each of the patients, which was taken as the golden rule of the diagnosis and also the determination of plasmatic antithyroglobulin antibodies by the TCR method and the determination of antimicrosomal antibodies were made for statistically validating both methods, taking sensitivity, specificity, predictive value for positive cases, predictive value for negative cases and general index of diagnostic efficacy into consideration. Seventy patients were found positive and 30 negative for CAT by the FNB. The sensitivity of both methods of humoral antibodies was poor: 45.7 % for AMS and 30 % for TRC. Even the joint application of both methods to the same patient did not exceed 60 %. Specificity was a much better indicator in both methods (73.3 % for AMS, 90 % for TRC and 70 % for both applied together. The predictive value for positive cases was good (80 % for AMS; 87.5 % for TRC and 82.3 % for both and the predictive value for negative cases was 36.3, 35.5 and 42.9 % respectively. The general efficacy was only 54 % for TRC, 48 % for AMS and 63 % for both methods together. It was concluded that these procedures are useful to confirm the diagnosis when cases are positive, but they are rather useless to assure the non-existence of this affection when cases are negative

    Periadrenal and adrenal portosystemic collaterals are a recently reported cause of adrenal pseudotumor on computed tomography (CT). Nine patients with this left adrenal pseudotumor illustrate its typical position and appearance on CT, angiography, CT-angiography, and magnetic resonance imaging (MRI). The anatomic basis for variceal adrenal pseudotumors is the left inferior phrenic vein, which passes immediately anterior to the left adrenal gland and which serves as a collateral pathway from splenic to left renal vein in portal hypertension. Thus, unlike previously described adrenal pseudotumors, these venous collaterals are not anatomically distinguishable from the adrenal gland on CT. Bolus dynamic CT is usually diagnostic, but in equivocal cases, MRI may prove useful

    A freeze dried kit formulation for the preparation of {sup 99m}Tc-labelled human polyclonal IgG for the detection of infection and inflammation employing direct methods for protein labeling was developed. The method comprises reduction of intrinsic disulphide bridges within the antibody molecule by the use of the reductant 2-mercaptoethanol. Following a subsequent purification, the resulting reduced antibody is labeled via Sn{sup 2+} reduction of pertechnetate in the presence of a weak competing ligand ethane-1-hydroxy-1,1-diphosphonate (EHDP). High labeling efficiencies (>90%) were obtained with high in vitro stability and without effect upon antibody immunoreactivity. Methods of analysis were also established permitting identification of radiochemical impurities which may be present in radiopharmaceutical solution. {sup 99m} Tc-polyclonal IgG prepared by the kit method was evaluated for scintigraphic localization of inflammatory lesions and abscesses in rabbits. Data demonstrated that the {sup 99m} Tc-polyclonal IgG after kit-reconstitution shows excellent stability and is an effective imaging agent of infection and/or inflammation. (Author).

    This study aimed the observation of inflammatory process decrease by the use of GaAlAs Low Intensity Laser ({lambda}=830 nm; 40 mW) irradiation. Five patients were selected and submitted to surgery of impacted lower third molars, both right and left sides at different occasions. On a first stage, a tooth of a random chosen side - right or left - was extracted by conventional surgery, without LILT. The inflammatory process was measured at postoperative on the first, third and seventh days. This side was then called 'control side'. After 21 days, period in which the inflammatory process of the first surgery was terminated, the other side surgery took place, this time using LILT (4 J at four spots) at postoperative, first and third days. As the previous surgery, the inflammatory process was also measured at postoperative on the first, third and seventh days. This side was called 'experimental or lased side'. The inflammatory process was evaluated by measuring its four characteristic signs: swelling, pain, color and temperature. It was clearly observed a decrease for swelling, pain and color on the lased side which presented significant inference and descriptive statistics. It can be concluded that GaAlAs Low Intensity Laser ({lambda}=830 nm) can surely be used as an additional and important anti-inflammatory source on impacted lower third molar surgeries. (author)

    Full Text Available La cardiomiopatía periparto es una entidad clínica con una frecuencia variable de acuerdo con la zona en estudio. Se caracteriza por disfunción sistólica del ventrículo izquierdo y posterior aparición de síntomas de falla cardiaca, los cuales ocurren durante el último mes de gestación y los primeros meses post- parto. Su etiología aún no es clara, pero se plantean diferentes teorías, las cuales se basan en fenómenos inflamatorios, infecciosos y auto-inmunes. Recientemente, se describieron alteraciones relacionadas con el estrés oxidativo, que podrían explicar en gran medida esta patología. Su presentación clínica guarda gran similitud con las demás causas de falla cardíaca, aunque se han descrito presentaciones atípicas. Su diagnóstico requiere alto nivel de sospecha y debe considerarse en toda mujer con síntomas de falla cardíaca durante el periparto. El tratamiento convencional de la falla cardiaca crónica que incluye beta-bloqueadores, inhibidores de la enzima convertidora de angiotensina y diuréticos, además de los adelantos en el diagnóstico y manejo de la falla cardiaca aguda, permitió cambiar la historia de la enfermedad al disminuir la mortalidad y recuperar la función sistólica del ventrículo izquierdo. Las gestaciones posteriores al desarrollo de esta entidad, dependerán de la recuperación completa de la función cardíaca, sin disminuir el riesgo de recurrencia. Todavía existen múltiples preguntas por responder en áreas como etiología, factores de riesgo, tratamiento y marcadores pronósticos que permitan prevenir y manejar en forma oportuna y segura tanto a la madre como a su hijo.Peripartum cardiomyopathy is a clinical entity with a variable frequency according to the zone of the study.

    2010-02-01

    Full Text Available La esclerosis múltiple (EM es una enfermedad inflamatoria autoinmune desmielinizante del sistema nervioso central (SNC. La mayoría de las enfermedades autoinmunes se originan por la activación anormal de la respuesta inflamatoria contra auto-antígenos (la mayoría de ellos desconocidos a la fecha como consecuencia de la pérdida de la tolerancia periférica. Las células T-regulatorias constituyen un grupo esencial de linfocitos T encargados del mantenimiento de la tolerancia periférica, la prevención de enfermedades autoinmunes y la limitación de enfermedades inflamatorias crónicas. Teniendo en cuenta la importancia de la tolerancia periférica, las células T-regulatorias serían componentes cruciales en el escenario fisiopatológico de los procesos autoinmunes, incluyendo la EM. El presente trabajo recopila los conocimientos actuales sobre la función de las células T-regulatorias en la EM, la enfermedad autoinmune desmielinizante del SNC más prevalente en los seres humanos.Multiple sclerosis (MS is an autoimmune inflammatory demyelinating disease of the central nervous system (CNS. Most of autoimmune diseases arise by an abnormal activation of the inflammatory response against self-antigens (most of them unknown up to date as a consequence of dysfunction in peripheral tolerance. Regulatory T-cells are essential for maintaining peripheral tolerance, preventing autoimmune diseases and limiting chronic inflammatory conditions. Based on that knowledge, T-regulatory cells have emerged as a key component of the physiopathology of autoimmune diseases including MS. This review compiles the current knowledge on the role and function of T-regulatory cells in MS, the most prevalent CNS autoimmune disease in humans.

Nuestro objetivo fue evaluar la presencia y distribución de placas vulnerables e infiltrados inflamatorios en pacientes fallecidos por infarto agudo de miocardio y su comparación con los hallazgos en pacientes fallecidos por cuadros no coronarios. Se analizaron los estudios anatomopatológicos de corazón de 68 pacientes fallecidos por infarto agudo de miocardio y 15 fallecidos por causa no coronaria. Se registró la presencia de trombo, hemorragia intraplaca, ruptura endotelial e infiltrado inflamatorio. Al evaluar los pacientes fallecidos por IAM, encontramos trombo en 73.5% de las arterias responsables del IAM y en 28.7% de las no responsables (p < 0.0001. La hemorragia intraplaca se halló en el 70.5% de las arterias responsables y en 39.7% de las no responsables, p < 0.0001; ruptura endotelial en el 29.4% de las arterias responsables y en 3.7% de las no responsables, p < 0.0001. No encontramos diferencias en la presencia de infiltrado inflamatorio (76.5% versus 68.4%.

    2017-06-01

    Full Text Available Metal-on-metal (MoM total hip arthroplasty (THA is associated with increased incidence of failure from metallosis, adverse tissue reactions, and the formation of pseudotumors. This case highlights a 53-year-old female with an enlarging painful thigh mass 12 years status post MoM THA. Radiographs and advanced imaging revealed an atypical mass with cortical bone destruction and spiculation, concerning for periprosthetic malignancy. Open frozen section biopsy was performed before undergoing revision THA in a single episode of care. This case illustrates that massive pseudotumors can be locally aggressive causing significant femoral bone destruction and may mimic malignancy. It is important that orthopaedic surgeons, radiologists and pathologists understand the relative infrequency of periprosthetic malignancy in MoM THA to mitigate patient concerns, misdiagnosis, and allow for an evidence based discussion when treating massive pseudotumors.

    2007-01-01

    Objective: To explore the value of spiral CT in the diagnosis of atypical pulmonary nodules. Methods: CT, clinic and histopathologic data of 72 patients with atypical pulmonary nodules confirmed by surgical resection in 41 cases and/or biopsy in 31 cases were retrospectively analyzed. Results: CT scans demonstrated slight lobulation in 34 cases, irregular margin in 50 cases, long speculate in 10 cases, air-bronchogram in 2 case, vacuole in 2 case. 38 pulmonary cancer, 22 pulmonary tuberculosis and 12 pulmonary inflammatory pseudotumors were diagnosed with spiral CT. However, 30 pulmonary cancer, 30 pulmonary tuberculosis and 12 pulmonary inflammatory pseudotumors were confirmed by histopathology. The overall accurate diagnostic rate of pulmonary cancer was 66.7% (20/30), pulmonary tuberculosis was 60%(18/30), pulmonary inflammatory pseudotumors was 16.7%(2/12). 40 cases were diagnosed correctly and 32 cases were misdiagnosed with CT in 72 cases of atypical pulmonary nodules. The misdiagnostic rate of CT was 44.4%. 10 cases of lung cancer were misdiagnosed, including 4 cases of tuberculosis (long speculate or irregular margin) and 6 cases of inflammatory pseudotumors (irregular margin or long speculate or air-bronchogram). 12 cases of tuberculosis were misdiagnosed, including 8 cases lung cancer (slight lobulation) and 4 cases of inflammatory pseudotumors (slight lobulation). 10 cases inflammatory pseudotumor were misdiagnosed as lung cancer (slight lobulation). Conclusion: Spiral CT was very useful in the localization and morphological describing, but difficult in qualitative diagnosing of atypical pulmonary nodules, exactly diagnosis was relied on surgery and biopsy.

    Full Text Available El desarrollo de enfermedades autoinmunes es un tema de suma importancia cuando de vacunas se trata, dado el riesgo que pueden tener éstas de favorecer fenómenos de autoinmunidad en individuos susceptibles. La relación riesgo/beneficio de desarrollar enfermedades autoinmunes luego de la vacunación contra el virus del papiloma humano (VPH aún no se ha resuelto. Los datos disponibles son limitados para ofrecer conclusiones definitivas. Dado el aumento reciente de reporte de efectos adversos, se espera que estudios con suficiente tamaño muestral, en diversas poblaciones, confirmen la seguridad de la vacunación contra el VPH en niñas con enfermedades autoinmunes. Un análisis personalizado de cada paciente, que incluya la evaluación de autoinmunidad personal y familiar, podría ser sugerido, aunque no hay estudios que demuestren que sea costo-efectivo. Por lo tanto, la farmacovigilancia permanente de esta vacuna sigue siendo de suma importancia.

    Full Text Available Resumen La aterosclerosis es una enfermedad de tipo inmunoinflamatoria, en la cual los mecanismos fisiopatológicos incluyen patrones de inflamación y cambios epignéticos que alteran la expresión genética de varios mediadores inflamatorios y no inflamatorios. La epigenética está ofreciendo explicaciones sobre cómo la dieta, los factores ambientales y el estilo de vida pueden influir en la aparición y progresión de la enfermedad, y cómo las alteraciones pueden ser transmitidas a las siguientes generaciones sin que haya modificaciones en las secuencias de ADN. Las estatinas, a través de los efectos pleiotrópicos, ofrecen una herramienta de gran ayuda en el control de la progresión de las placas y sus subsiguientes repercusiones.

    The Inflammatory Pseudotumor of the Liver is an uncommon benign tumor in occidental countries and its etiology remains unclear. Its diagnosis is difficult, because there are no specific symptoms, analytic abnormalities or radiologic findings, and is usually mistake with other hepatic tumors inducing its inadequate resection. The histological examination is the gold standard for the diagnosis of Inflammatory Pseudotumor of the Liver. There is no consensus about the ideal treatment. In the majority of cases, the prognosis is excellent with the complete resolution of the lesion. In this paper, it is reported one case of Inflammatory Pseudotumor of the Liver diagnosed during the investigation of a hepatic lesion in a man with history of alcohol abuse but without stigmata of chronic liver disease and with a normal serum alpha-fetoprotein level. Given the histological result of Inflammatory Pseudotumor of the Liver and benign associated with it, has remained a expectant attitude and there was resolution of symptoms, normalization of analysis and complete disappearance of the lesion.

  3. Vacunas y autoinmunidad: una rara asociación bajo debate Vaccines and autoimmunity: a strange association under debate

    Directory of Open Access Journals (Sweden)

    Alexander Batista-Duharte

    2012-06-01

    Full Text Available La posible asociación entre vacunas y enfermedades autoinmunes es un tema controversial. Existen elementos a favor de esta relación basados en modelos teóricos, ensayos de laboratorio y varios casos clínicos publicados. En cambio, los estudios epidemiológicos no han confirmado esta asociación y, de ellos, puede inferirse que las vacunas no constituyen una causa demostrada de enfermedades autoinmunes. En este trabajo se analizan las evidencias a favor y en contra de esta controversial asociación, además, se aborda un nuevo síndrome asociado con la administración continuada de adyuvantes vacunales. Se concluye que debido al gran impacto en beneficio de la salud logrado con las vacunas, es necesario continuar desarrollando esta tecnología, pero también se debe seguir perfeccionando los diseños de las nuevas formulaciones y profundizando estudios básicos, preclínicos, ensayos clínicos y farmacovigilancia de los nuevos candidatos vacunales para establecer el riesgo real de desarrollo de un evento autoinmune posvacunación.The occurrence and significance of autoimmune manifestations after administration of vaccines remain controversial. Evidence for immunization triggered autoimmunity come from several sources including theoretical models, animal studies, single and multiple case reports. In contrast, several epidemiological studies don’t report this association, which is reassuring and at least indicates that vaccines are not a major cause of autoimmune diseases. We analyzed current scientific data concluded that vaccines bring a positive impact on public health, so it is necessary to continue developing this technology. Evaluation methods should be improved to avoid or anticipate the possible autoimmune side effects that can be presented.

    Full Text Available O elastofibroma dorsal, pseudotumor de partes moles com crescimento lento, tem sido cada vez mais lembrado no diagnóstico diferencial de dor escapular crônica, sendo também diagnosticado incidentalmente em exames de diagnóstico por imagem de rotina. Abordamos aqui o diagnóstico por imagem que pode começar pela radiografia convencional, mas é melhor caracterizado pelo ultrassom e pela ressonância magnética, sendo esta última a modalidade de escolha.Elastofibroma dorsi, a slow-growing, soft-tissue pseudotumor has been more and more remembered in the differential diagnosis of chronic scapular pain. It has also been incidentally diagnosed in routine diagnostic imaging tests. Our approach here is the imaging diagnosis, which can start with the conventional X-ray, but is better characterized by the ultrasound and the magnetic resonance, the latter being the modality of choice.

    We report a case of acute orbital myositis. A 61-year-old woman exhibited acute orbital pain, diplopia, and left proptosis. Examination revealed a 5-mm left proptosis, left chemosis, and limitations in all directions of the movement of the left eye. Visual acuity was unimpaired, however, and the neurological examination was otherwise normal. CT demonstrated a left inferior orbital mass. We suspected an acute orbital pseudotumor based on the rapid onset and the clinical symptoms. We treated her with systemic corticosteroids. Four weeks later CT documented a reduced left orbital mass; there seemed to be left only an inferior rectus muscle enlargement. We diagnosed acute orbital myositis, a subgroup of orbital pseudotumors, based upon the rapid clinical presentation, the CT features, and the resolution after treatment with systemic corticosteroids.

    2011-01-01

    Full Text Available Inflammatory myofibroblastic tumor is an uncommon lesion of unknown cause. It encompasses a spectrum of myofibroblastic proliferation along with varying amount of inflammatory infiltrate. A number of terms have been applied to the lesion, namely, inflammatory pseudotumor, fibrous xanthoma, plasma cell granuloma, pseudosarcoma, lymphoid hamartoma, myxoid hamartoma, inflammatory myofibrohistiocytic proliferation, benign myofibroblatoma, and most recently, inflammatory myofibroblastic tumor. The diverse nomenclature is mostly descriptive and reflects the uncertainty regarding true biologic nature of these lesions. Recently, the concept of this lesion being reactive has been challenged based on the clinical demonstration of recurrences and metastasis and cytogenetic evidence of acquired clonal chromosomal abnormalities. We hereby report a case of inflammatory pseudotumor and review its inflammatory versus neoplastic behavior.

    1982-01-01

    The computed tomographic morphology of malignant choroidal melanoma and its perfusion characteristics are described. Thirty-three static and serial CT examinations made on 29 patients with choroidal melanoma, three with pseudotumors of the macula and one with choroidal metastasis revealed the choroidal melanoma to be usually a hyperdense, markedly perfused tumor, while the non-contrast, diagnostically undifferentiable pseudotumors and the choroidal metastasis, revealed no significant change in density after the administration of contrast material. Density values or perfusion characteristics of choroidal melanoma that are outside of the normal range are a result of secondary changes within the immediate surroundings of the tumor, such as detachment of the retina, tumor-induced glaucoma, or tumor necrosis.

    Focal myositis is a pseudotumor of soft tissue that typically occurs in the deep soft tissue of the extremities, and is a relatively rare lesion. There is a wide clinical spectrum, with approximately one-third of patients with focal myositis subsequently developing polymyositis, and clinical symptoms of generalized weakness, fever, myalgia, and weight loss, with elevation of creatine phosphokinase. We report the case of a patient with focal myositis who subsequently developed myositis ossificans-like features. (orig.)

    The "gliogenic" participation in the edification of granulomas may produce peculiar morphological features especially in the central nervous system, and perhaps more than elsewhere, pseudotumoral features. Moreover, the concept of "granuloma" is perhaps not as well defined as in the other tissues. There are also some still unsolved problems concerning the histogenesis of the cells of the "granuloma". Some examples taken among the different etiologies illustrate these notions.

    The optic nerves are well demonstrated by high-resolution computed tomography. Involvement of the optic nerve by optic gliomas and optic nerve sheath meningiomas is well known. However, nonneoplastic processes such as increased intracranial pressure, optic neuritis, Grave ophthalmopathy, and orbital pseudotumor may also alter the appearance of the optic nerve/sheath on computed tomography. Certain clinical and computed tomographic features permit distinction of these nonneoplastic tumefactions from tumors

    Hepatic involvement is usually secondary to abdominal actinomycosis infection. Symptom onset is typically subscute and the disease follows a chronic and indolent course. These lesions are called inflammatory pseudotumors and cannot be differentiated from malignant tumors by radiological examination alone. Laboratory tests showed mild anemia; hemoglobin 119 g/L, elevated white blood cell count of 23,060/mm 3 , AST 33 U/L, ALT 45 U/L, and γ-GT 155 U/L.

    In patients with progressive scleroderma, interstitial calcifications are present to a varying extent. They are mostly located in the soft tissues of the fingers, resembling points, commas or dashes. They may also appear as 'calcinosis universalis' and reach a considerable size. Thus they mimic proliferative tumors. Scintigraphy, proving the existence of further calcifications can be helpful. We report the case of a female patient who presented with such a 'pseudotumor' of unusual size, site and extent in the lumbar region. (orig.) [de

    1975-01-01

    Computerized tomography is clearly very useful in the evaluation of patients with increased intracranial pressure and suspected pseudotumor cerebri. It provides an index of ventricular size and configuration and has the capability of demonstrating intracranial lesions. Moreover, this new technique is rapid and non-invasive, and is without attendant risks. Examinations may be performed serially as the clinical process evolves, thereby giving roentgenographic correlation to the clinical features. (U.S.)

  17. CT findings of orbital inflammatory diseases

    International Nuclear Information System (INIS)

    Kim, Jang Min; Shin, Hyun Joon; Kim, Jung Hyuk; Suh, Won Hyuck

    1991-01-01

    Twenty-nine patients with orbital inflammatory disease (OIDs) were retrospectively reviewed in order to analyze detailed CT findings which might aid in differentiating OIDs. This study comprised 18 pseudotumors, 5 thyroid ophthalmopathies, and 6 cases of orbital cellulitis. CT scans of the pseudotumors showed various findings such as exophthalmos, scleritis, myositis of the extraocular muscle (MOM), and bone lesion. Bone lesions of the pseudo tumors, which have been rarely reported, were present in 7 cases in our series. Bilateral exophthalmos, myositis, and retrobulbar fat deposition were readily detected by CT in thyroid ophthalmopathy, and, in addition, we found bone erosions involving the orbital apices in 2 cases. In orbital cellulitis, extraorbital soft tissue swelling and lateral displacement of the medial rectus muscle in cases with ethmoiditis were the most conspicuous features. In summary, because of the overlapping CT findings in OIDs, careful examination of CT findings regarding the mode of EOM involvement and the presence or absence of scleritis or sinusitis might help narrow down the differential diagnosis. A pseudotumor with bone lesions could be mistaken as a malignant lesion, and therefore it is necessary to correlate clinical features with CT findings for an accurate diagnosis

    Thirty-two patients with orbital pseudotumor (18), reactive lymphoid hyperplasia (2), atypical lymphoid infiltrate (4) or malignant lymphoma (8) were treated in the Division of Radiation Therapy at Stanford University between January 1973 and May 1983. Of the 20 patients with pseudotumor or reactive lymphoid hyperplasia, 10 had unilateral lesions and 10 had bilateral lesions. Biopsy samples were obtained in 15 patients; in five patients with bilateral disease the diagnosis was made on the basis of computed tomography (CT) and clinical findings. The majority of patients were referred because of disease refractory to treatment with corticosteroids. The patients were given a mean dose of 2360 rad using complex, individualized megavoltage techniques including lens shielding. Radiotherapy was well tolerated with no significant acute or late complications. Fifteen patients had complete resolution of symptoms after treatment; five had continued symptoms. Of the 12 patients with malignant lymphoma or atypical lymphoid infiltrate, four had systemic lymphoma with orbital involvement and eight had orbital involvement only. A mean dose of 3625 rad was delivered to the orbit only. Most of the patients received complex megavoltage treatment using bolus. All patients in this group had a complete response and local control. Two patients developed cataracts. Carefullly planned orbital radiotherapy provides local control without symptomatic sequelae for orbital masses ranging from pseudotumor to malignant lymphoma

    La obesidad se caracteriza por un estado inflamatorio de bajo grado que produce alteraciones metabólicas y hemodinámicas a nivel sistémico. El conjunto de alteraciones cardiacas producidas por la obesidad, es lo que se conoce como “cardiomiopatía de la obesidad”. En adultos los mecanismos de la remodelación cardiaca en el contexto de la obesidad son complejos y dada la prevalencia de los trastornos comórbidos y las variables de confusión concomitantes con la obesidad es dificultoso caracteriz...

    Los procesos inflamatorios, frecuentemente asociados a anemia de enfermedades crónicas, podrían cumplir un rol en la inhibición de la eritropoyesis. La existencia de señales intracelulares comunes entre los procesos que regulan la eritropoyesis y la respuesta inflamatoria sugiere que la desregulación de un sistema podría explicar la disminución de la función del otro. Por otro lado, un daño directo sobre los eritrocitos maduros en circulación, causado por factores presentes en dichos procesos...

    Full Text Available Se ha planteado que la hormona de crecimiento (GH y la Prolactina (PRL pueden intervenir en procesos infecciosos como inmunomoduladores vía receptores específicos; revelando una conexión entre el sistema inmune y el sistema endocrino en los tejidos, donde actúan como citoquinas a través de diferentes rutas de señalización. Igualmente, la hepcidina (HAMP, hormona producida en los hepatocitos como respuesta al exceso de hierro y a estímulos inflamatorios, es considerada un enlace entre el metabolismo del mineral, la defensa del hospedero y los procesos inflamatorios, debido a su capacidad de privar del hierro a los microorganismos. Se sugiere que en un proceso infeccioso, la síntesis, secreción y regulación de GH ocurre a través de la producción de citoquinas como factor de necrosis tumoral alfa (TNF-α e interleuquina-1 beta (IL-1β, las cuales actúan en el hipotálamo, estimulando la liberación ya sea de la hormona liberadora de somatotropina o de somatostatina; por otro lado, se ha reportado que células linfoides, incluyendo linfocitos T y B y células dendríticas, producen GH, PRL biológicamente activa con propiedades inmunoreguladoras.

    Augmented Reality (AR) guidance is a technology that allows a surgeon to see sub-surface structures, by overlaying pre-operative imaging data on a live laparoscopic video. Our objectives were to evaluate a state-of-the-art AR guidance system in a tumor surgical resection model, comparing the accuracy of the resection with and without the system. Our system has three phases. Phase 1: using the MRI images, the kidney's and pseudotumor's surfaces are segmented to construct a 3D model. Phase 2: the intra-operative 3D model of the kidney is computed. Phase 3: the pre-operative and intra-operative models are registered, and the laparoscopic view is augmented with the pre-operative data. We performed a prospective experimental study on ex vivo porcine kidneys. Alginate was injected into the parenchyma to create pseudotumors measuring 4-10 mm. The kidneys were then analyzed by MRI. Next, the kidneys were placed into pelvictrainers, and the pseudotumors were laparoscopically resected. The AR guidance system allows the surgeon to see tumors and margins using classical laparoscopic instruments, and a classical screen. The resection margins were measured microscopically to evaluate the accuracy of resection. Ninety tumors were segmented: 28 were used to optimize the AR software, and 62 were used to randomly compare surgical resection: 29 tumors were resected using AR and 33 without AR. The analysis of our pathological results showed 4 failures (tumor with positive margins) (13.8%) in the AR group, and 10 (30.3%) in the Non-AR group. There was no complete miss in the AR group, while there were 4 complete misses in the non-AR group. In total, 14 (42.4%) tumors were completely missed or had a positive margin in the non-AR group. Our AR system enhances the accuracy of surgical resection, particularly for small tumors. Crucial information such as resection margins and vascularization could also be displayed.

    Muscle atrophy is seen in patients with metal-on-metal (MOM) hip implants, probably because of inflammatory destruction of the musculo-tendon junction. However, like pseudotumors, it is unclear when atrophy occurs and whether it progresses with time. Our objective was to determine whether muscle atrophy associated with MOM hip implants progresses with time. We retrospectively reviewed 74 hips in 56 patients (32 of them women) using serial MRI. Median age was 59 (23-83) years. The median time post-implantation was 83 (35-142) months, and the median interval between scans was 11 months. Hip muscles were scored using the Pfirrmann system. The mean scores for muscle atrophy were compared between the first and second MRI scans. Blood cobalt and chromium concentrations were determined. The median blood cobalt was 6.84 (0.24-90) ppb and median chromium level was 4.42 (0.20-45) ppb. The median Oxford hip score was 34 (5-48). The change in the gluteus minimus mean atrophy score between first and second MRI was 0.12 (p = 0.002). Mean change in the gluteus medius posterior portion (unaffected by surgical approach) was 0.08 (p = 0.01) and mean change in the inferior portion was 0.10 (p = 0.05). Mean pseudotumor grade increased by 0.18 (p = 0.02). Worsening muscle atrophy and worsening pseudotumor grade occur over a 1-year period in a substantial proportion of patients with MOM hip implants. Serial MRI helps to identify those patients who are at risk of developing worsening soft-tissue pathology. These patients should be considered for revision surgery before irreversible muscle destruction occurs.

    Full Text Available Modular neck femoral components were introduced to optimize femoral neck anteversion, leg length, offset, and stability in total hip arthroplasty. However, concerns have been raised in recent years regarding early failure of these implants due to corrosion, pseudotumor, as well as fracture of the modular neck. Removing modular neck femoral implants is challenging as removal of the modular femoral neck leaves a proximally coated femoral stem level with the proximal bone of the femoral neck. We describe a posterior femoral single limb osteotomy  (posterior cut of an extended trochanteric osteotomy for the removal of a modular neck femoral component.

    Extramedullary hematopoiesis (EMH) is the production of blood cell precursors outside the bone marrow that occur in various hematological diseases. In patients with thalassemia intermedia, ineffective erythropoiesis drives compensatory EMH in the liver, pancreas, pleura, spleen, ribs and spine. We describe a patient with thalassemia intermedia who presented with acute neurological symptoms caused by paraspinal EMH, which responded well to combination therapy of steroid, hypertransfusion, laminectomy and excision of pseudotumor and hydroxyurea therapy to boost the formation of fetal haemoglobin. Prompt recognition of EMH based on clinical presentation and typical radiological findings should be made. Early treatment is recommended to prevent irreversible damage to the spinal cord.

A different radiologic presentation of this disorder is described. The gross appearance of the lesion, previously undescribed, appears to be rather specific for such a pseudoneoplastic disorder, and correlates very well with the magnetic resonance imaging features.

    Focal myositis is a pseudotumor of soft tissue that typically occurs in the deep soft tissue of the extremities, and is a relatively rare lesion. There is a wide clinical spectrum, with approximately one-third of patients with focal myositis subsequently developing polymyositis, and clinical symptoms of generalized weakness, fever, myalgia, and weight loss, with elevation of creatine phosphokinase. We report the case of a patient with focal myositis who subsequently developed myositis ossificans-like features. (orig.) With 3 figs., 25 refs.

    Tuberculosis of the spleen is not exceptional. The authors report ten cases which occurred with a predominance in young male adults. All patients had at least one other site of tuberculosis without any HIV infection. All patients had focal splenic lesions in the form of scattered hypo-echogenic and hypodense nodules. These nodules had a pseudo-tumor appearance in one case. CT-guided puncture was performed in one case. Splenic tuberculosis is not as rare as is sometimes thought. The CT-guided splenic puncture is now performed routinely and remains the ideal diagnostic approach. (authors). 9 refs., 5 figs

    2004-01-01

    Focal lesions of the liver often have various imaging characteristics which may be interpreted as either benign or malignant. Understanding the underlying pathophysiology of these liver lesions may lead to characteristic imaging manifestations, which direct the radiologist to the diagnosis. Benign lesions include congenital hepatic cyst, autosomal dominant polycystic disease, hemangioma, focal nodular hyperplasia (FNH), hepatic adenoma, inflammatory pseudotumor, peliosis hepatis, focal fatty infiltration, hamartoma, and infectious processes such as hepatic abscess, echinococcal cyst, and candidiasis. Characteristic imaging features, clinical symptoms, and treatment/prognosis will be discussed. Emphasis will be placed on key reliable features of each disease to develop a method of discriminating these lesions from other benign and malignant disorders.

    Full Text Available Fibromatosis colli is an uncommon benign, congenital fibrous tumor or pseudotumor of the sternocleidomastoid muscle that manifests in infancy. In some of these patients tightening of the muscle results in torticollis. We report the case of a 3-week-old child, who presented with a neck mass localized in the left side with reduced mobility of the head. The diagnosis of fibromatosis colli was raised by ultrasound sonography. The mass regressed spontaneously within 3 months without surgical or physical treatment.

    In patients with progressive scleroderma, interstitial calcifications are present to a varying extent. They are mostly located in the soft tissues of the fingers, resembling points, commas or dashes. They may also appear as 'calcinosis universalis' and reach a considerable size. Thus they mimic proliferative tumors. Scintigraphy, proving the existence of further calcifications can be helpful. We report the case of a female patient who presented with such a 'pseudotumor' of unusual size, site and extent in the lumbar region.

    The roentgenographic recognition of gastric varices often is difficult, even when there is a history of liver disease or splenomegaly without demonstrable esophageal varices. An apparant polypoid filling defect with exaggerated mucosal folds in proximal portion of the gastric body and funds on upper GI series, accompanied by hematemesis and splenomegly should suggest the presence of pseudotumoral gastric varices. We have an experience a case of polypoid filling defects in gastric fundus of psudotumoral gastric varices of 49 years old Korean woman, which was diagnosed by surgical and histopathological findings

    Full Text Available Soft tissue injuries constitute 30-50% of all sports related injuries; however, injury to the latissimus dorsi muscle is quite rare with only a few cases reported in the literature. Herein, we describe an acute traumatic tear of the latissimus dorsi muscle in an elite track athlete, which has not been reported in the track and field sports before. The injury was caused by forceful resisted arm adduction that took place at hurdling and starting from the block. A pseudotumor appearance in the axillary region was misdiagnosed as a mass. The diagnosis was made by ultrasound alone and the patient was managed conservatively.

    Myositis ossificans (MO) is an inflammatory pseudotumor of the muscle that may be mistaken clinically and even histologically for a malignant soft tissue tumor. The aim of this article is to report the imaging characteristics of MO, the emphasis being on the early diagnostic clues. USG can be used at an early stage to reveal the ‘zone phenomenon,’ which is highly suggestive of MO. A short course of nonsteroidal anti-inflammatory drug therapy may be an efficient treatment for early MO

    1988-01-01

    Ultrasonographic, computed tomographic, and angiographic abnormalities of nodular regenerative hyperplasia have been described in very few cases. We report here the case of a 50-year-old man with round, well-limited hypoechogenic lesions involving the two lobes of the liver, and hypervascular, poorly delineated angiographic lesions. Computed tomography and magnetic resonance of the liver were normal. Histological examination of large liver specimens provided by intraoperative biopsy allowed the diagnosis of nodular regenerative hyperplasia. Such a pseudo-tumoral ultrasonographic and angiographic pattern must be recognized in order to avoid diagnostic and therapeutic mistakes, especially since percutaneous liver biopsy usually fails to diagnose this disease.

    Full Text Available We describe seven cases of children (ages 2 to 14 years with myeloradiculopathy caused by infection with S. mansoni. None of them presented hepatosplenic involvement and one presented an intestinal picture. The myeloradicular and pseudotumoral forms were observed in four and three patients, respectively. Comparing the reports in the literature, we found that the pseudotumoral form is more similary frequent among children than in adults, while the myelitic and myeloradicular forms are the most frequent and distributed across all age groups. Diagnosis is based on clinical and epidemiological findings in association with laboratory tests. The diagnosis was confirmed by the presence of S. mansoni eggs in feces (5 cases and / or the positivity in specific immunological tests (5 cases associated with a cerebrospinal fluid inflammatory pattern with presence of eosinophils (between 1 and 24%. Magnetic resonance image, although it does not enable an etiological diagnosis, helped to confirm the form and spinal cord level of the lesion.Relatamos sete crianças com mielorradiculopatia devida a infecção pelo S. mansoni, com idade entre 2 e 14 anos. Nenhuma apresentou acometimento hepatoesplênico e uma apresentou quadro intestinal. A forma mielorradicular foi observada em quatro pacientes e a pseudotumoral em três. Revendo os achados da literatura, encontramos que a forma pseudotumoral é mais frequente nas crianças que nos adultos, apesar das formas mielíticas e mielorradiculares serem ainda as mais frequentes em todas as idades. O diagnóstico baseou-se nos achados clínicos e epidemiológicos, associados aos laboratoriais. A presença de ovos de S. mansoni nas fezes (5 casos e/ou a positividade de testes imunológicos específicos no liquido cefalorraquidiano (5 casos, com padrão inflamatório e eosinofilorraquia (entre 1 e 24% confirmou o diagnóstico.

    2012-01-01

    Full Text Available Paratesticular/scrotal and inguinal canal mass lesions in elderly patients may pose a diagnostic challenge to both the surgeon as well as the pathologist. In most cases, these represent hernial sacs with their contents, and true neoplasms like lipomas, rhabdomyosarcomas, and fibrous pseudotumors are infrequent. Malignant mesotheliomas arising from the tunica layers are rare cause of inguinal and paratesticular tumors. Herein, we report a case of an elderly patient who presented with an inguinal hernia which pathologically had features of deciduoid malignant mesothelioma.

    Full Text Available La caries dental que vulnera los tejidos duros del diente y compromete a la pulpa provoca un proceso inflamatorio que progresa por varias fases o estadios: pulpitis reversible, pulpitis transicional, pulpitis irreversible y pulpa necrótica. El tejido pulpar agredido por microorganismos no experimenta una necrosis repentina, sino que va sucumbiendo progresivamente, y cada uno de los estadios pulpares por los que transita el proceso, se puede ir identificando mediante el dolor con sus características semiológicas propias de cada fase, lo que permite precisar con bastante certeza el estado pulpar por el que avanza el proceso inflamatorio en dicho tejido. La interpretación fisiopatológica de los diferentes estadios pulpares por los que transita una pulpitis y el seguimiento del dolor como síntoma cardinal del proceso inflamatorio, es una forma de diagnóstico que complementa el pensamiento interpretativo del clínico que atiende estas urgencias, y le permite una mejor comprensión de su evolución y establecer así el correcto tratamiento.The dental caries that harms the hard tissues of the tooth and compromises the pulp produces an inflammatory process that progresses through various phases or stages: reversible pulpitis, transitional pulpitis, irreversible pulpitis and necrotic pulp. The pulpar tissue attacked by microorganisms does not experiment a sudden necrosis, but it progressively succumbs and each of the pulpar stages the process goes through may be identified by the pain with its own semiological characteristics of every stage, which allows to determine with enough accuracy the pulpar stage through which the inflammatory process advances in this tissue. The physiopathological interpretation of the different pulpar stages of a pulpitis and the follow-up of pain as a cardinal symptom of the inflammatory process is a form of diagnosis complementing the interpretative thinking of the clinician that gives attention to these emergencies

    Full Text Available The aim of the present research was to discover plant food extracts and probiotics that may have bioactivity towards chronic inflammation. Three plant food extract mixtures expected to be rich in phenolic compounds, carotenoids and tocopherols were prepared. The anti-inflammatory activity of the different mixtures as well as probiotic bacteria (Bifidobacterium bifidum were evaluated in adjuvant arthritis in rats. The anti-inflammatory effect, mechanism of action and safety of the three mixtures and Bifidobacterium bifidum were studied by measuring the size of inflammation and the determination of inflammatory and oxidative stress biomarkers, colonic bacteria profile and specific cytogenetic parameters. The contents of tocopherols, β-carotene and phenolic compounds in the mixtures were determined. The results show that the tested mixtures and Bifidobacterium bifidum possess promising anti-inflammatory effects. The mechanism of action seems to involve a reduction in oxidative stress and inflammatory biomarkers and an effect on colonic microflora. Genotoxicity and DNA fragmentation induced by adjuvant arthritis were prevented after supplementation with the tested mixtures.El objetivo de la presente investigación fue encontrar extractos de alimentos vegetales y probióticos que puedan tener bioactividad hacía la inflamación crónica.

    2009-08-01

    Full Text Available La esclerosis múltiple es una enfermedad autoinmune, inflamatoria y desmielinizante del sistema nervioso central, de etiología desconocida y evolución crónica. Existen diferentes hipótesis etiológicas que hablan de una estrecha interrelación entre factores genéticos predisponentes y factores ambientales disímiles, capaces de desencadenar la respuesta autoinmune a nivel del sistema nervioso central. La hipótesis de la patogenia autoinmune se basa en estudios en modelos experimentales y hallazgos en biopsias de pacientes afectados por la enfermedad. Datos acumulativos reportan que el estrés oxidativo desempeña una función fundamental en la patogénesis de la esclerosis múltiple. Las especies reactivas de oxígeno generadas por macrófagos han sido implicadas como mediadoras de la desmielinización y el daño axonal, tanto en la encefalomielitis autoinmune experimental, como en la esclerosis múltiple propiamente. El diagnóstico de la enfermedad es difícil porque no existe una única prueba confirmatoria. El tratamiento de la esclerosis múltiple abarca el tratamiento de los relapsos agudos y los síntomas, así como la modificación de la enfermedad. Estos aspectos requieren un enfoque individualizado, basado en la evolución de esta afección y la tolerabilidad de los tratamientos. Además de la dieta, entre los tratamientos no farmacológicos para la esclerosis múltiple se recomienda la terapia física. Por otra parte, se han realizado varios ensayos clínicos en los que se han empleado extractos naturales, suplementos nutricionales y otros agentes con resultados alentadores. La farmacología ha dotado a los neurólogos de un amplio arsenal de fármacos de probada eficacia; sin embargo, los resultados de los laboratorios de investigación en los últimos años hacen muy probable que las posibilidades terapéuticas aumenten considerablemente en el futuro.Multiple sclerosis is an autoimmune, inflammatory and desmyelinization

    Full Text Available Se informa que la artritis reumatoidea es una enfermedad autoinmune inflamatoria y sistémica, cuya causa aún no se ha precisado, pero es de suponer varios factores que son importantes en su patogenia, entre ellos, factores ambientales, genéticos (asociados con el complejo principal de histocompatibilidad y con los genes que codifican la síntesis de inmunoglobulina, del receptor de célula T, citocinas y moléculas de adhseión. Estos factores, al interactuar, median el daño articular propio de la enfermedad, con participación de los sucesos de la respuesta inmune. También se mencionan otros mecanismos de daño articular por activación de oncogenes, que regulan tanto la apoptosis, como la activación de enzimas proteolíticas que contribuyen a la formación del pannusIt is reported that rheumatoid arthritis is a systemic autoinmune inflammatory disease whose causes are yet unelear but several factors are supposed to be important in its pathogenesis such as environmental factors and genetic factors (linked to the main histocompatibility complex and to coding genes for the synthesis of inmunoglobulin, T-cell receptors, cytokines and adhesive molecules. When these factors interact, they mediate the articular damage inherent to the disease where inmune response events also participate. Additionally, other mechanisms of articular damage by oncogene priming are presented. They regulate both apoptosis and proteolytic enzime priming contributing to pannus formation

    Full Text Available El balance redox ha sido reconocido, de forma cada vez más creciente, como un componente crítico del proceso de envejecimiento; la iniciación y desarrollo de enfermedades de notable morbilidad y mortalidad (aterosclerosis, cáncer, enfermedades del sistema nervioso central, enfermedades autoinmunes, daño por isquemia-reperfusión, entre otras y respuestas celulares, inducidas por el estrés oxidativo. Estrechamente vinculado con el estrés oxidativo está la generación de especies reactivas de oxígeno las cuales provocan daño celular directo, además de actuar como segundos mensajeros intracelulares al modular las vías de transducción de señales. En el presente trabajo se recogen los principales antecedentes de las investigaciones relacionadas con este tema y se describen las más importantes características de las especies reactivas del oxígeno.The redox balance has been increasingly recognized as a critical component of the aging process; the onset and development of diseases causing dramatic morbidity and mortality (atherosclerosis, cancer, central nervous system diseases, autoinmune diseases, ischemia-reperfusion damage, among others and oxidative stress-induced cellular responses. Closely related to oxidative stress is the generation of oxygen reactive species, which cause direct cell damage in addition to acting as second intracellular messengers when modulating signal transduction pathways. The present paper presented the main antecedents of pieces of research related to this topic and described the most important characteristics of the oxygen reactive species.

    Full Text Available Ventriculo-peritoneal shunts (VPS are commonly used in the treatment of various neurosurgical conditions, including hydrocephalus and pseudotumor cerebri. We report only the second case of vaginal extrusion of a VPS catheter in an adult, and the first case with a modern VPS silastic peritoneal catheter. A 45-year-old female with a history of VPS for pseudotumor cerebri, Behcet′s syndrome, and hysterectomy presented to our institution with the chief complaint of tubing protruding from her vagina after urination. On gynecologic examination, the patient was found to have approximately 15 cm of VPS catheter protruding from her vaginal apex. A computed tomography scan of the abdomen and shunt X-ray series demonstrated no breaks in the tubing, but also confirmed the finding of the VPS catheter extruding through the vaginal cuff into the vagina. The patient had the VPS removed and an external ventricular drain was placed for temporary cerebrospinal fluid diversion. Ventricular catheter cultures were positive for diphtheroids. After an appropriate course of antibiotics, a contralateral ventriculo-pleural shunt was placed one week later. Although vary rare, vaginal extrusion can occur in adults, even with modern VPS catheters.

    Full Text Available We report a case of a 43-year-old female who presented with right ear fullness and otorrhea. She was initially diagnosed with mastoiditis that was not responsive to multiple courses of antibiotics and steroids. She was then diagnosed with refractory inflammatory pseudotumor, and subsequent treatments included several mastoidectomies, further steroids, and radiation therapy. The patient went on to develop mastoiditis on the contralateral side as well as central nervous system involvement with headaches and right-sided facial paresthesias. Reexamination of the mastoid tissue revealed a significantly increased number of IgG4-positive cells, suggesting a diagnosis of IgG4-related disease. The patient improved clinically and radiographically with rituximab and was able to taper off azathioprine and prednisone. IgG4-related disease should be considered in patients with otologic symptoms and be on the differential diagnosis in patients with inflammatory pseudotumor. Staining for IgG and IgG4 is essential to ensure a prompt diagnosis and treatment.

    Inflammatory conditions belong to the most important diseases of the orbit. Children and adolescents are mostly affected and the most common cause is secondary pathogen invasion from acute sinusitis. However in adults most cases involve idiopathic orbital inflammation, previously termed pseudotumor orbitae. Clinical presentation may include painful exophthalmus, skin redness and warming, chemosis and disturbed eye motility. The challenge for imaging investigations, mainly a combination of CT scanning and MRI, is to distinguish inflammatory from malignant conditions, to define the extent of lesions and to document possible complications, such as cavernous sinus thrombosis, meningoencephalitis or cerebral abscesses. Serious potential consequences of orbital infections, including loss of vision or death, are still a risk factor and must be averted by avoidance of delays in diagnosis and appropriate clinical management. (orig.) [German] Entzuendliche Veraenderungen zaehlen zu den wichtigen Erkrankungen der Orbita. Meist sind Kinder und Jugendliche betroffen, wobei eine fortgeleitete Infektion der Nasennebenhoehlen die haeufigste Ursache darstellt. Bei Erwachsenen handelt es sich in den meisten Faellen um eine idiopathische Orbitaentzuendung - frueher unter dem Begriff Pseudotumor orbitae zusammengefasst. Zu den Leitsymptomen zaehlen schmerzhafter Exophthalmus, Ueberwaermung und Roetung der Haut, Chemosis sowie eine Bewegungseinschraenkung des Bulbus. Die Rolle bildgebender Verfahren - hier ergaenzen sich Computer- und Magnetresonanztomographie - besteht in der Differenzierung inflammatorischer und tumoroeser Prozesse und insbesondere in der Darstellung der Laesionsausdehnung sowie dem Nachweis von Komplikationen, wie einer Sinus-cavernosus-Thrombose, einer Meningoenzephalitis oder zerebralen Abszessen. Auch heute noch koennen Infektionen der Orbita schwerwiegende Folgen wie komplette Erblindung oder Tod nach sich ziehen. (orig.)

    The lacrimal fossa can be involved by a wide spectrum of orbital pathology. The correct diagnosis is important to avoid unnecessary procedure and to do appropriate management. 14 patients with mass lesions in the lacrimal fossa were evaluated with computed tomography (CT) and clinical findings. The results were as follows: 1. Final diagnosis of 14 cases with lacrimal fossa tumors was pleomorphic adenoma in 3 cases, adenoid cystic carcinoma in 1 case, pseudotumor in 5 cases, lymphoma in 2 cases, neurofibroma in 1 case, chloroma in 1 case and metastatic adenocarcinoma in 1 case. 2. The duration of symptoms of pleomorphic adenoma was more than 1 year and characteristic CT findings were globular masses with pressure erosion of the adjacent bone. Patient with adenoid cystic carcinoma had a short history of symptoms. CT showed a fusiform mass but intracranial extension with frank destruction of sphenoid bone. 3. Patients with pseudotumor and lymphoma had symptoms for less than 1 year. The CT findings were ill-defined infiltrative patterns with scleral thickening and the differential diagnosis of them was difficult. 4. The margins of neurofibroma and chloroma were well defined while that of the metastic adenocarcinoma was ill-defined. 5. The degree and the extent of the contrast enhancement gave no benefit in the differential diagnosis of each disease entities and even of the benign and malignant lesions

    Highlights: •Conventional non-contrast MRI is unable to distinguish CKD pseudotumors from RCCs. •Pseudotumours in a background of CKD do not show restricted diffusion. •CKD pseudotumours demonstrate high ADC values whereas RCCs show restricted diffusion. •DW-MRI is reliable in ruling out malignancy incase of pseudotumours found in chronic kidney disease. •DW-MRI may obviate contrast administration and/or tissue sampling in renal pseudotumours and prevent inadvertent surgeries. -- Abstract: Objectives: To evaluate whether diffusion-weighted MRI (DW-MRI) can distinguish pseudotumours in chronic kidney disease (CKD pseudotumours) from renal-cell-carcinomas (RCCs) (with or without CKD) and whether it offers additional benefit over conventional MRI. Methods: One-hundred patients underwent MDCT, MRI and DW-MRI (at b-values of 0 and 500 s/mm 2 ) for evaluation of focal renal lesions. Of these, 20 patients with 40 CKD pseudotumours and 36 patients with 40 RCCs were retrospectively analyzed. T1-weighted, T2-weighted, diffusion-weighted images were evaluated, apparent-diffusion-coefficient (ADC) values were compared and receiver-operating-characteristic (ROC) curves were drawn to establish cut-off ADC-values. Results: 92.5% of CKD pseudotumours remained indeterminate after conventional MRI. On DW-MRI, none of them showed restricted diffusion and thus malignancy could be ruled out in 100% of the lesions. In contrast, all the solid RCCs showed diffusion restriction. Mean ADC-value for CKD pseudotumours was significantly higher than RCCs and surrounding diseased parenchyma [2.50 vs 1.56 (×10 −3 mm 2 /s) (P < 0.0001) and 2.05 (×10 −3 mm 2 /s) (P = 0.0001) respectively]. ROC analysis for differentiating CKD pseudotumours and RCC yielded high sensitivity (91.7%) and specificity (100%) for cut-off ADC-value of 2.04 (×10 −3 mm 2 /s). Conclusions: CKD pseudotumors usually remain indeterminate on conventional non-contrast MRI. DW-MRI can distinguish CKD pseudotumors

    The development of computed tomography (CT) provided a noninvasive safe technique for imaging the orbit in any plane exquisitely demonstrating its normal anatomy as well as its pathologic process. The orbit is an ideal structure to be examined by CT because of large difference of absorption values between the intraorbital fat, muscle, optic nerve and vessels. In this study, the authors reviewed CT findings of 66 pathologically proven orbital tumors and tumorous conditions among the total of 98 cases who had taken orbital CT scan because if exophthalmos, ocular pain, diplopia and other ophthalmologic symptoms suggesting orbital masses during the period of 3 years. For the analysis of characteristic CT findings of the orbital lesions, all lesions are divided into 4 groups according to the site of origin, i.e., tumors arising in the eyeball (group 1); from intraconal space (group 2); from extraconal space (group 3); and from extraorbital regions (group 4).

    Full Text Available La falla ovárica precoz es una amenorrea secundaria que se presenta en una mujer antes de los 40 años, que conlleva a hipoestrogenismo, infertilidad y las consecuencias de la menopausia prematura, como osteoporosis, enfermedad cardiovascular, trastornos neurovegetativos, entre otros. Se presenta agotamiento folicular, por dotación insuficiente de folículos o destrucción acelerada de los ovocitos. Las causas son varias, pero predominan las genéticas, autoinmunes y las iatrogénicas. Entre las causas genéticas, son frecuentes las deleciones Xq y Xp, las translocaciones, aberraciones numéricas (47,XXX, 45,X0, premutaciones de X frágil, entre otros. Entre las enfermedades autoinmunes son de importancia la insuficiencia poliglandular tipo I y II. Las iatrogenias pueden ser quirúrgicas en ovarios o trompas y, con la presencia del cáncer de mama en mujeres jóvenes, el tratamiento oncológico puede destruir las células germinales, por lo que hoy se sugiere utilizar técnicas de preservación de la función ovárica y de la fertilidad. En el manejo de la falla ovárica precoz, una vez determinada la causa, se sugiere el uso de terapia estrogénica, aunque no se ha hecho investigación en el tipo de hormona a utilizar, dosis y consecuencias a largo plazo. Tener presente la prevención y manejo de la osteoporosis y la enfermedad cardiovascular. Con relación a la infertilidad, se está realizando criopreservación de embriones y ovocitos para autodonación, así como criopreservación de tejido ovárico cortical para autotrasplante posterior, con éxitos y limitaciones. Los agonistas de GnRH podrían actuar en proteger los ovarios en casos de quimioterapia. Se observa con atención la terapia génica experimental en casos de falla ovárica precoz.

    Langerhans cell histiocytosis (LCH) is a rare disease characterized by the accumulation within tissues of anomalous dendritic cells similar to Langerhans cells. The clinical presentation varies, ranging from the appearance of a single bone lesion to multisystemic involvement. Central nervous system (CNS) involvement, manifesting as diabetes insipidus secondary to pituitary involvement, has been known since the original description of the disease. Two types of CNS lesions are currently differentiated. The first, pseudotumoral lesions with infiltration by Langerhans cells, most commonly manifests as pituitary infiltration. The second, described more recently, consists of neurodegenerative lesions of the CNS associated with neurologic deterioration. This second type of lesion constitutes a complication of the disease; however, there is no consensus about the cause of this complication. Our objective was to describe the radiologic manifestations of LCH in the CNS in pediatric patients. Copyright © 2013 SERAM. Published by Elsevier España, S.L.U. All rights reserved.

  7. Benign Intracranial Hypertension with Particular Reference to Its Occurrence in Fat Young Women

    1966-01-01

    Benign intracranial hypertension (pseudotumor cerebri), a syndrome common to a number of disorders, is characterized by headaches and blurred vision. The patient is alert and has papilledema without localizing signs. Air studies show normal ventricles under increased pressure. The authors describe 61 consecutive cases of this pseudotumour, 48 of which were in fat young women, and propose that this group represents a clinical entity that has hitherto received little attention. In these 61 patients, 40 complete-exchange pneumoencephalograms showed normal ventricles, normal fluid volume and prominent cortical sulci. In 32, subtemporal decompression resulted in prompt and lasting relief. Three patients had late convulsive seizures after surgery. Seven patients had nasal quadrantanopsias, the implications of which are discussed. The authors believe that the high intracranial pressure in this condition is due to cerebral hyperemia, not brain edema. Further investigation will perhaps demonstrate a relationship between obesity, vascular dilatation and increased intracranial pressure. ImagesFig. 1 PMID:5296376

    Three years following an irradiation by the Betatron's electron beam of an epithelioma in left parieto occipital area of the scalp in a female patient aged 77, early suffering from high blood pressure, a fatal pseudo-tumoral brain necrosis occurs presenting as a rapidly increasing from of Wernicke's aphasia. The necropsy shows intense radionecrosis lesions of the brain and the bone, free of any parenchymatous malignant proliferation note-wortly for the striking density of microvascular changes as previously described in radiation therapy. The case observed some years ago, allows to definite again the limits doses of the extracranial irradiations now estimated at 1760 rets. That is the 'Nominal Standard Dose' (NSD) measured by rets and taking into account the number of seances (N) and the duration of irradiation (T) which would be to take the place of 'the total dose' (D) (rads). These dosimetric criteria themselves must be adjusted to the age and the vascular features of each patient [fr

    With conventional methods including orbital arteriography, orbital venography, penumoobitography and positive contrast orbitography, imaging of eyeball and orbit is not only difficult, invasive or expensive but also nonspecific in result. Ultrasonography provides safe, specific and reliable way to obtain image of eyeball and orbit. Fifty six ultrasonograms of 50 patients which were referred under the impression of various ophthalmic diseases were analyzed. 1. Sixteen cases were normal. 2. Ocular diseases were 26 cases and extraocular orbital diseases were 8 cases. 3. Among the ocular diseases, 9 foreign body cases, 6 retinal detachment cases, 5 vitreous hemorrhage 4. Among the extraocular orbital diseases, 6 pseudotumor cases, 1 pseudolymphoma, 1 eyelid cyst case were diagnosed. 5. Ultrasonic findings were specific enough to differentiated from diseases and well corresponded with clinical and pathological diagnosis. 6. It can be concluded that ultrasonography is one of the most reliable imaging method in ocular and extraocular orbital diseases

    Extramedullary hematopoiesis (EMH) is a systemic reaction to inadequate hematopoiesis. We report two exceedingly rare cases of EMH involving the paranasal sinuses. The first patient, a 30-year-old man, presented with a maxillary sinus mass. The lesion was excised by endoscopic surgery: definitive histology identified foci of EMH within an inflammatory fibromyxoid pseudotumor. The second case occurred in a 29-year-old man affected by intermediate beta-thalassemia. He was hospitalized with a diagnosis of sphenoid sinus mucocele secondary to an ethmoid lesion. The patient underwent endoscopic excision of the mass and drainage of the sphenoid mucocele. At definitive histology, a diagnosis of EMH was established. Herein, the presenting modalities, imaging profile, and treatment options of this rare EMH localization are reviewed. Copyright (c) 2009 Elsevier Ireland Ltd. All rights reserved.

    2012-01-01

    Full Text Available Inflammatory myofibroblastic tumor (IMT has been described as a pseudosarcomatous proliferation of spindled myofibroblasts admixed with lymphoplasmacytic cells. The various terminologies like inflammatory pseudotumor, plasma cell granuloma, and inflammatory myofibrohistiocytic proliferation, used to describe this entity, highlight the controversial etiopathogenesis of this relatively indolent neoplasm. IMT has now been described in different anatomic locations. However, cases occurring in the gastrointestinal tract are rare with very few cases described in the appendix. We present a case of inflammatory myofibroblastic tumor appendix with mucosal dysplasia in a 41-year-old male, presenting with abdominal pain and lump in the right iliac fossa. Aspiration cytology yielded few atypical epithelial cells and spindle cells in a mucinous background, suggesting the possibility of pseudomyxoma peritonei. Awareness of IMT appendix with rare presence of mucosal dysplasia may help in preventing overzealous resection, especially in situations that on preoperative evaluation may suggest malignancy.

    Full Text Available Mycetomas are inflammatory pseudo-tumors in multiple locations that affect the skin, the subcutaneous tissues and, sometimes, the bones. Their treatment depends on the type of parasite. Fungal mycetomas, also called eumycetomas, are treated mainly through surgery, while actinomycotic mycetomas are treated primarily with drugs. We report here the case of a 14-year-old girl afflicted with a giant cervico-facial mycetoma. The patient was born to poor and illiterate parents in a rural area of the Diffa province, at 1500 km from the capital city of Niamey. Histological examination of a biopsy specimen allowed a diagnosis of actinomycetoma due to Streptomyces somaliensis. The patient showed a remarkable sensitivity to ketoconazole, but she ultimately died due to a lack of sufficient medication.

    Objective: To evaluate the clinical application of multi-slice CT-guided percutaneous transthoracic lung coaxial-biopsy for pulmonary lesions. Methods: 152 times of 143 patients were performed with percutaneous transthoracic coaxial biopsy under multiple-slice CT-guidance. Analysis was carried out to investigate the diagnostic accuracy and the relationship between the size of the lesions for coaxial biopsy, together with the complications. Results: The diagnostic accuracy was 94.9% with specificity of 100%, including malignant tumors 116 cases (squamous cell cancer 48 cases, adenocarcinoma 34, small cell undifferentiated carcinoma 6, large cell carcinoma 4, bronchial alveolar carcinoma 8, metastatic carcinoma 16) and 19 cases of benign ones(TB 7 cases, inflammatory pseudotumor 9, hematoma 1, lung abscess 1). The size of lesion had a significant influence on the diagnostic accuracy. Conclusions: Percutaneous transthoracic coaxial lung biopsy is a safety method, possessing a high diagnostic accuracy.

  14. Histochemical and ultrastructural study of an elastofibroma dorsi coexisting with a high grade spindle cell sarcoma

    Directory of Open Access Journals (Sweden)

    M Alberghini

    2009-06-01

    Full Text Available Elastofibroma dorsi is a pseudotumoral fibroproliferative lesion characterized by polymorphic fiber-like deposits of elastinophilic material. Several theories have been reported explaining the pathogenesis of elastofibroma. Recent cytogenetic studies have demonstrated chromosomal instability in elastofibromas, not normally observed in non-neoplastic tissues. These chromosomal defects are commonly observed in aggressive fibromatosis too. Such clinical observations suggest a multistage pathogenetic mechanism for the onset of elastofibroma. This study, using histochemical, immunohistochemical staining techniques, and ultrastructural examination, describes the detection of an otherwise typical elastofibroma contextual to a high grade sarcoma. Hence, the coexistence of elastofibroma and high-grade sarcoma may suggest a causal link between the two pathological entities. The results obtained suggest that the coexistence of the two pathological entities is conceivably coincidental.

    The inflammatory pseudo tumor is a non neoplastic process characterized by an irregular growth of inflammatory cells. We described the case of a 38 year-old patient, she went to our institute for a in situ cervix cancer and left lung nodule without breathing symptoms; valued by neumology who did bronchoscopy with biopsy whose result was negative for malignancy. She went to surgery in where we find intraparenquima nodule in felt lingula of approximately 4 cms, we remove it; the result was: Inflammatory pseudotumor. This pathology is a not very frequent, it can develop in diverse regions of the organism, it is frequent in lung. The image tests are not specific for the diagnose, which it is possible only with the biopsy. The treatment is the complete resection. (The author)

    Soft tissue tumors of the knee are rare in childhood. Modern imaging modalities are very useful to evaluate these tumors. Their diagnosis has to be considered in view of the clinical content, their precise location and imaging features. Succinct review of the normal anatomy of the knee is made. We offer a diagnostic approach to these tumors in children including conventional radiology, ultrasound and MRI. We discuss the role of the different imaging techniques available for the diagnosis of these lesions, including pseudo-tumors such as popliteal cysts, hematoma, ossifying myositis, extra-articular benign and malignant tumors, as well as intra-articular lesions, synovial lipoma, osteochondromatosis and pigmented villo-nodular synovitis. MRI is particularly useful to evaluate the extent of the malignant tumors. (authors)

    Focal myositis are inflammatory muscle diseases of unknown origin. At the opposite from the other idiopathic inflammatory myopathies, they are restricted to a single muscle or to a muscle group. They are not associated with extramuscular manifestations, and they have a good prognosis without any treatment. They are characterized by a localized swelling affecting mostly lower limbs. The pseudo-tumor can be painful, but is not associated with a muscle weakness. Creatine kinase level is normal. Muscle MRI shows an inflammation restricted to a muscle or a muscle group. Muscle biopsy and pathological analysis remain necessary for the diagnosis, showing inflammatory infiltrates composed by macrophages and lymphocytes without any specific distribution within the muscle. Focal overexpression of HLA-1 by the muscle fibers is frequently observed. The muscle biopsy permits to rule out differential diagnosis such a malignancy (sarcoma). Spontaneous remission occurs within weeks or months after the first symptoms, relapse is unusual. Copyright © 2017. Published by Elsevier SAS.

    Focal myositis is a rare, mostly benign disease (pseudotumor) of skeletal muscle, histopathologically characterized by interstitial myositis and tumorous enlargement of a single muscle. The etiology of focal myositis remains unknown; however, localized myopathy has been postulated to be caused by denervation lesions. This case report describes a patient that presented with clinical, laboratory, electromyoneurography, and magnetic resonance imaging features of focal myositis complicated with intervertebral disk protrusion in the lumbosacral spine affected with radicular distress. In most cases, focal myositic lesions show spontaneous regression, relapses are rare, and long-term prognosis is good. There is a wide spectrum of therapeutic options, from no therapy at all through nonsteroidal antirheumatics and glucocorticoids to radiotherapy, surgical excision, and immunosuppressants. In the patient presented, treatment with glucocorticoids, methotrexate, and surgical excision failed to produce satisfactory results. Clinical improvement, pain relief, and reduction in lower leg volume were only achieved by local infiltration of botulinum A toxin.

  19. Magnetic resonance neurography for the identification of pudendal neuralgia

    Directory of Open Access Journals (Sweden)

    Claudia P. Cejas

    2017-06-01

    Full Text Available The pudendal nerve entrapment is an entity understudied by diagnosis imaging. Various causes are recognized in relation to difficult labors, rectal, perineal, urological and gynecological surgery, pelvic trauma fracture, bones tumors and compression by tumors or pelvic pseudotumors. Pudendal neuropathy should be clinically suspected, and confirmed by different methods such as electrofisiological testing: evoked potentials, terminal motor latency test and electromyogram, neuronal block and magnetic resonance imaging. The radiologist should be acquainted with the complex anatomy of the pelvic floor, particularly on the path of pudendal nerve studied by magnetic resonance imaging. High resolution magnetic resonance neurography should be used as a complementary diagnostic study along with clinical and electrophysiological examinations in patients with suspected pudendal nerve neuralgia.

    Tarasyuk, S.V.; Letyagin, V.P.

    1986-01-01

    The paper presents data on 52 cases of breast cancer disseminated into cranial vault bones (2 into the orbit). Metastases into the brain (2) and meninges (6) were detected in 17 cases with the aid of computerized tomography of the brain and examination of cerebrospinal fluid. The latter cases were not included into the study group. Metastases into cranial bones were identified by craniography and scanning of the skeleton. Half the patients (18 out of 35) revealed the following neurologic syndromes which were determined by the site of metastases into cranial vault bones and tumour growth pattern (into cranial cavity or soft tissues of the head): lesions in ramus primus nervi trigemini, greater occipital nerve, migraine, pseudotumorous and pseudoencephalitic syndromes. Cases of such neurologic disorders require an all-round examination including ophthalmooscopy, EEG, computerized tomography of the brain, craniography and scanning of the skeleton

    2014-02-01

    Perineal nodular induration (PNI) is a fibroblastic pseudotumor that presents almost exclusively in male cyclists. It develops in the soft tissues of the perineum immediately posterior to the scrotum, as a bilateral or single, central or lateralized mass. Although well known to sport medicine specialists, it is a scarcely documented entity in the pathology literature. We present 2 cases of PNI with fine-needle aspiration cytology and immunohistochemistry. They consisted of a paucicellular fibroblastic proliferation containing CD34-reactive spindle and epithelioid cells, small foci of fibrinoid degeneration, numerous blood vessels, and entrapped groups of mature fat cells. Our cases show that the histopathological features of PNI are more varied than those previously described and its immunohistochemical profile is wider. A central cystic focus and a zonal pattern are not consistent features of this entity. The lesional cells can express CD34, a hitherto unreported immunohistochemical finding.

    Ten cases of histologically confirmed intraorbital tumors were studied with magnetic resonance imaging (MRI). Two meningiomas were nearly isointense on the T 1 -weighted image (T 1 WI) and the T 2 -weighted image (T 2 WI) relative on the cerebral cortex. The hemangiopericytoma, lacrimal gland tumor, optic glioma, and encephalocele were hypointense on the T 1 WI. The pseudotumor was hypoisointense on both the T 1 WI and the T 2 WI. The metastatic tumor (prostatic carcinoma) was hyperintense on both the T 1 WI and the T 2 WI. Gd-DTPA MRI was performed in five cases. The anatomical relationships between the tumor and the orbital tissue could be discriminated well by means of the coronal and sagittal views. MRI is thus found to be useful for the preoperative diagnosis of the intraorbital tumor and the selection of the surgical approach. (author)

    To develop a lung cancer diagnosis system. A retrospective analysis was conducted in 1883 patients with primary lung cancer or benign pulmonary diseases (pneumonia, tuberculosis, or pneumonia pseudotumor). SPSS11.5 software was used for data processing. For the relevant factors, a non-factor Logistic regression analysis was used followed by establishment of the regression model. Microsoft Visual Studio 2005 system development platform and VB.Net corresponding language were used to develop the lung cancer diagnosis system. The non-factor multi-factor regression model showed a goodness-of-fit (R2) of the model of 0.806, with a diagnostic accuracy for benign lung diseases of 92.8%, a diagnostic accuracy for lung cancer of 89.0%, and an overall accuracy of 90.8%. The model system for early clinical diagnosis of lung cancer has been established.

    This review summarizes topical papers from the fields of neuro-ophthalmology and neuro-otology published from August 2013 to February 2015. The main findings are: (1) diagnostic criteria for pseudotumor cerebri have been updated, and the Idiopathic Intracranial Hypertension Treatment Trial evaluated the efficacy of acetazolamide in patients with mild vision loss, (2) categorization of vestibular disorders through history and ocular motor examination is particularly important in the acute vestibular syndrome, where timely distinction between a central or peripheral localization is essential, (3) the newly described "sagging eye syndrome" provides a mechanical explanation for an isolated esodeviation that increases at distance in the aging population and (4) eye movement recordings better define how cerebellar dysfunction and/or sixth nerve palsy may play a role in other patients with esodeviations that increase at distance.

    1990-01-01

    This paper defines the diagnostic and prognostic value of MR imaging in chronic progressive radiation myelopathy 9CPRM). In this series, MR imaging showed excellent sensitivity (199%) for the demonstration of radiation-induced lesions of the spinal cord. Fifty percent of the cases showed spinal cord hypertrophy (pseudotumoral, 33%; cystic, 17%) occurring within 8 months of the clinical onset of myelopathy. The remaining 50% showed spinal cord atrophy, which occurred more than 8 months following the onset of myelopathy. These medullary lesions were located at least partially in the radiation field but extended beyond its boundaries in 73% of the cases. MR imaging helped to establish disease prognosis: spinal cord hypertrophy was usually associated with neurologic deterioration and fatal outcome within a mean of 11.5 months; in spinal atrophy, neurologic deficit was often static and survival rates were better

    Full Text Available Inflammatory myofibroblastic tumors (IMT are uncommon neoplasms of the lung in adults. They constitute less than 1% of all lung neoplasms and usually present as parenchymal masses. Diagnosis requires a high index of suspicion. They are characterized by spindle-shaped tumor cells (fibroblasts/myofibroblasts in a background of lymphoplasmacytic infiltrate. About 50% of the tumors harbor an ALK gene rearrangement. They have to be differentiated from inflammatory pseudotumors (IPT, which show increased number of IgG4 plasma cells on immunostaining and are negative for anaplastic lymphoma kinase (ALK protein. Herein, we present a case of a 28-year old female who presented with hemoptysis and was diagnosed with an IMT of lung in the first trimester of pregnancy. We have not only reviewed the occurrence of IMT during pregnancy but also discuss the management options for IMT during pregnancy.

    Full Text Available Multiple enlarged lymph nodes in an elderly female patient can have varied etiologies as well as histologic pictures. We are presenting the case of a 53-year-old female who presented with inguinal lymphadenopathy with fever, which was clinically misconstrued as lymphoma. Cytology could not exclude a lymphoma. Histology led to the unusual diagnosis of inflammatory myofibroblastic tumor of lymph node in this case. Inflammatory myofibroblastic tumor of the lymph node is a rare, distinctive reactive proliferative pattern in the lymph node which involves proliferation of the connective tissue elements of the lymph node, admixed with lymphocytes, plasma cells, eosinophils, and histiocytes. Multiple etiologic agents have been suggested in existing literature. Despite extensive search, no definite attributable cause could be sought. It is now widely accepted that inflammatory pseudotumor of the lymph node is a non-neoplastic proliferation which has a benign clinical course and excellent prognosis after surgical resection.

    Imaging of Graves' orbitopathy (GO) includes radiological and nuclear medicine procedures. Depending on the method used they provide information about the distribution and activity of the disease. Magnetic resonance imaging (MRI) is not only a helpful tool for making the diagnosis it also enables differentiation of the active and inactive forms of GO due to intramuscular edema. The modality is therefore appropriate to evaluate the disease activity and the course of therapy. The disease leads to the typical enlargement of the muscle bodies of the extraocular muscles. The inferior rectus, medial rectus and levator palpebrae muscles are mostly involved. Signal changes of the intraconal and extraconal fat tissue are possible and a bilateral manifestation is common.

    Sixty five cases with orbital and ocular lesions were evaluated by MRI in comparison with high resolution CT. MRI was performed with spin echo techniques (short TR/TE and long TR/TE) using a 0.22 tesla resistive unit (Toshiba MRT-22A) or a 1.5 tesla superconductive unit (Siemens Magnetom). MRI was superior to CT in (1) detecting ocular lesions and vitreous changes, (2) differentiating a tumor from the adjacent extraocular muscles and optic nerves, (3) identifying the lesion in the orbital apex and demonstrating the posterior extent of the tumor and (4) detecting the abnormal flow in the orbital vascular structures. Although some tumors had specific signal intensities including hemangioma, menigioma, and pseudotumor, majority of tumors revealed non-sepcific signal intensities. CT was superior to MRI in detection for small and calcified lesions as well as visualization of bone details. (author).

    Full Text Available We report a rare presentation of an initially misdiagnosed case of a pseudotumor, which on histopathology was diagnosed as bilateral breast metastases of lobular carcinoma involving multiple extraocular muscles. A 61-year-old lady presented with external ophthalmoplegia and diplopia. Incisional biopsy was performed using a lid crease approach and the patient received radiotherapy and hormonal therapy. Following prolonged hormonal therapy, complete remission was achieved, with improvement in ocular motility and resolution of diplopia, about 18 months after the initial presentation. Multiple extraocular muscle involvement by breast carcinoma metastasis is very rare and should be considered in the differential diagnosis, especially in patients with a prior history of breast carcinoma.

    Three years following an irradiation by the Betatron's electron beam of an epithelioma in left parieto occipital area of the scalp in a female patient aged 77, early suffering from high blood pressure, a fatal pseudo-tumoral brain necrosis occurs presenting as a rapidly increasing from of Wernicke's aphasia. The necropsy shows intense radionecrosis lesions of the brain and the bone, free of any parenchymatous malignant proliferation note-wortly for the striking density of microvascular changes as previously described in radiation therapy. The case observed some years ago, allows to definite again the limits doses of the extracranial irradiations now estimated at 1760 rets. That is the 'Nominal Standard Dose' (NSD) measured by rets and taking into account the number of seances (N) and the duration of irradiation (T) which would be to take the place of 'the total dose' (D) (rads). These dosimetric criteria themselves must be adjusted to the age and the vascular features of each patient.

    Full Text Available Plasma cell granuloma, also known as inflammatory pseudotumor is a tumor-like lesion that manifests primarily in the lungs. But it may occur in various other anatomic locations like orbit, head and neck, liver and rarely in the oral cavity. We here report an exceedingly rare case of gingival plasma cell granuloma in a 58 year old woman who presented with upper gingival polypoidal growth. The histopathological examination revealed a mass composed of proliferation of benign spindle mesenchymal cells in a loose myxoid and fibrocollagenous stroma along with dense infiltrate of chronic inflammatory cells predominantly containing plasma cells. Immunohistochemistry for kappa and lambda light chains showed a polyclonal staining pattern confirming a diagnosis of plasma cell granuloma.

    Our previous study showed a great attenuation for the Cerenkov luminescence endoscope (CLE), resulting in relatively low detection sensitivity of radiotracers. Here, a kind of radioluminescence nanoparticles (RLNPs), terbium doped Gd{sub 2}O{sub 2}S was mixed with the radionuclide {sup 68}Ga to enhance the intensity of emitted luminescence, which finally improved the detection sensitivity of the CLE by using the radioluminescence imaging technique. With the in vitro and in vivo pseudotumor experiments, we showed that the use of RLNPs mixed with the radionuclide {sup 68}Ga enabled superior sensitivity compared with the radionuclide {sup 68}Ga only, with 50-fold improvement on detection sensitivity, which guaranteed meeting the demands of the clinical diagnosis of gastrointestinal tract tumors.

    2013-01-01

    Turmeric root has been used medicinally in China and India for thousands of years. The active components are thought to be the curcuminoids, primarily curcumin, which is commonly available worldwide as a standardized extract. This article reviews the pharmacology of curcuminoids, their use and efficacy, potential adverse effects, and dosage and standardization. Preclinical studies point to mechanisms of action that are predominantly anti-inflammatory and antineoplastic, while early human clinical trials suggest beneficial effects for dyspepsia, peptic ulcer, inflammatory bowel disease, rheumatoid arthritis, osteoarthritis, uveitis, orbital pseudotumor, and pancreatic cancer. Curcumin is well-tolerated; the most common side effects are nausea and diarrhea. Theoretical interactions exist due to purported effects on metabolic enzymes and transport proteins, but clinical reports do not support any meaningful interactions. Nonetheless, caution, especially with chemotherapy agents, is advised. Late-phase clinical trials are still needed to confirm most beneficial effects.

    Objective: To evaluate the common cause of unilateral exophthalmos and CT findings. Methods: The CT manifestations of 267 cases of unilateral exophthalmos were reviewed. 41 cases were confirmed by surgery and pathology. 68 cases were confirmed by biopsy. Diagnosis was made in 158 cases on the basis of typical history, laboratory findings and response to treatment. Results: The lesions were intraocular (10 cases), intraorbital (230) and periorbital lesions (27). The most common causes of unilateral exophthalmos included inflammatory pseudotumor (67 cases), pleomorphic adenoma or carcinoma of lachrymal gland (44), cavernous angioma (22), carotid cavernous fistula (20) and varices (18). The CT appearances were exophthalmos, intraocular or periorbital tumor, extraocular muscle hypertrophy. The contrast enhancement was variable without enhancement in necrotic areas. Conclusion: CT scan is valuable for diagnosis and displaying the structural change of unilateral exophthalmos. (authors)

    Color Doppler imaging(CDI) has shortcomings, including random noise, aliasing, and angle dependence. To overcome these, a method using CD US, termed power doppler or Color Doppler Energy(CDE), has recently been introduced. The purpose of this study was to show the clinical usefulness of CDE. We retrospectively analyzed the CDI and CDE of 61 cases(20 renal pseudotumors, 8 musculoskeletal inflammations, 17 epididymitis or epididymo-orchitis, 3 varicoceles, 1 normal testis, 1 hepatocellualr carcinoma, 7 renal cell carcinoma, 1 renal angiomyolipoma, and 3 splenic varices). CDI and CDE scans were obtained at the same region with constant scan plane. The color gain was increased until noise first became perceptible, and scans were always obtained in such a way that the maximum amount of vascularity was shown. Thereafter, the vascularity, vascular displacement, and the vascular relationship between CDI and CDE were compared. In 17 of 20 cases of pseudotumor in the kidney, normal vascularity was identified in CDI and CDE, but was more cleary visible in CDE. In three cases, there was no visible vascularity in CDI, but normal vascularity in CDE. In eight cases of musculoskeletal inflammation and 17 cases of epididymitis with or without orchitis, the vascularity was increased due to hyperemia, which was more prominently seen in CDE than in CDI. In three varicoceles, CDE appeared to be better in demonstrating low velocity flow. In one patient who was suspected of having acute testicular torsion, CDE was helpful in excluding this suspicion. In one case of hepatocellualr carcinoma, seven cases of renal cell carcinoma, one case of renal angiomyolipoma, and three cases of splenic varices, CDE was better than CDI in showing the vascularity, vascular relationship, and vascular displacement

    Background: The Chiari Malformation I (CMI) is a disorder of uncertain origin that has been traditionally defined as downward herniation of the cerebellar tonsils through the foramen magnum. The anomaly is a leading cause of syringomyelia and occurs in association with osseous abnormalities at the cranio vertebral junction. In contrast to other Chiari malformations, CMI tends to present in the second or third decade of life and is sometimes referred to as the 'adult-type' Chiari malformation. The objective was to document clinical and radiological findings in Arnold Chiari Malformation-I. Method: This was a descriptive study carried out in Ayub Teaching Hospital Abbottabad at Neurosurgery Department during July 2008 - July 2010. We examined a prospective cohort of 60 symptomatic patients. All patients underwent magnetic resonance imaging of the head and spine. Results: There were 40 female and 20 male patients. The age of onset was 24.9 +- 15.8 years. Common associated radiological problems included syringomyelia (60%), scoliosis (25%), and basilar invagination (12%), increased cervical lordosis 5 (8.5%), and Klippel Feil syndrome 2 (3.3%). The most consistent magnetic resonance imaging findings were obliteration of the retrocerebellar cerebrospinal fluid spaces (70% patients), tonsillar herniation of at least 5 mm (100% patients), and varying degrees of post fossa anomalies. Linical manifestations were headaches, pseudotumor-like episodes, a Meniere's disease-like syndrome, lower cranial nerve signs, and spinal cord disturbances in the absence of syringomyelia. Conclusion: These data support accumulating evidence that CMI is a disorder of the para-axial mesoderm that is characterised by underdevelopment of the posterior cranial fossa and overcrowding of the normally developed hindbrain. Tonsillar herniation of less than 5 mm does not exclude the diagnosis. Clinical manifestations of CMI seem to be related to cerebrospinal fluid disturbances (which are responsible

    Full Text Available La liberación de ácido araquidónico o de otros ácidos grasos insaturados de 20 átomos de carbono, el icosatrienoico y el ecosapentanoico, de las reservas hísticas, es la primera fase de la síntesis de las prostaglandinas, tromboxanos y leucotrienos. Una vez liberado el ácido araquidónico de las reservas hísticas, se inicia su transformación en prostaciclina, prostaglandinas y tromboxano mediante la ciclación e incorporación de oxígeno molecular, catalizada por la ciclooxigenasa que está presente en la mayoría de las células. Las lipooxigenasas metabolizan también el ácido araquidónico hasta dar diversos productos con el grupo hidroxi-peroxi en posiciones distintas e incrementar así la síntesis de leucotrienos. Los metabolitos del ácido araquidónico, tanto de la vía de la ciclooxigenasa como de la lipooxigenasa, tienen una definida e importante participación en las diversas etapas del proceso inflamatorio. Diversos fármacos contribuyen a mejorar el proceso inflamatorio al inhibir enzimas específicas.The release of arachidonic acid or other unsaturated 20-carbon fatty acids, the icosatrienoic and icopentanoic acids, from hystic reserves is the first phase of the prostaglandins, thromboxines and leukotrienes synthesis. Once the arachidonic acid is released from thystic reserves, it is then turned into prostacyclines, prostaglandins and thromboxines through molecular oxygen cycling and addition catalyzed by cyclooxygenase present in the majority of cells. The lipoxygenases also metabolize the arachidonic acid into various products with hidroi-peroxi group in different positions and thus increase the leukotriene biosynthesis. The arachidonic acid metabolites resulted from both cycloxigenase and lipoxygenase action have a defined and important role in the various inflammatory process phases. Several pharmaceuticals assist in improving the inflammatory process by the inhibition of specific enzymes.

    Resumen Introducción: La patología de la unión cráneo-cervical es poco frecuente en la práctica neuroquirúrgica diaria. En general la mayor parte de estas lesiones son de origen traumático o reumatológico. La inestabilidad atlanto-axial de origen inflamatorio (Síndrome de Grisel) es una rara entidad de la que solo se han reportado 16 casos adultos en la literatura. Esta patología se caracteriza por el desarrollo de una lesión osteolítica a nivel de la articulación atlanto-axoidea posterior a un evento infeccioso, generalmente de las vías aéreas superiores. Descripción del caso: Presentamos el caso de una paciente de 76 años quien concurre en consulta por un cuadro clínico de inestabilidad cráneo espinal secundaria a una lesión osteolítica, con compromiso de C1 y C2. La sintomatología comenzó posteriormente a un proceso infeccioso respiratorio. Se realizó una fijación occípito-cervical posterior y una Odontoidectomía con descompresión anterior por vía endoscópica transnasal. La paciente evolucionó con resolución completa de los síntomas. Los cultivos fueron negativos y el estudio de anatomía patológica concluyó cambios inflamatorios inespecíficos. Conclusión: Hasta hace algunos pocos años la única opción para abordar esta patología era la vía transoral con técnica microquirúrgica. Hoy en día la endoscopía nos brinda muchas ventajas técnicas por lo que constituye una opción a tener en cuenta en la planificación de los abordajes a la unión cráneo-cervical. PMID:29430326

    Full Text Available Las inmunodeficiencias primarias son enfermedades genéticas, caracterizadas por infecciones crónicas devastadoras que conllevan a la muerte, al desarrollo de tumores y a enfermedades autoinmunes, y la mayoría de estas enfermedades cursan en la edad pediátrica. Desde la última década del pasado siglo, el desarrollo de la tecnología, el surgimiento del Proyecto del Genoma Humano y la profundización en los aspectos bioéticos, han dado lugar a especificidades en la atención médica e investigativa del paciente pediátrico y del que desarrolla una enfermedad inmunológica. Este trabajo recoge los aspectos bioéticos más importantes y los dilemas éticos con los que se enfrenta el inmunólogo pediátrico en la atención al paciente con inmunodeficiencia primaria, el cual demanda la atención de, prácticamente, todas las especialidades pediátricas.

    Mayrelis Quintero Busutil

    Full Text Available La cloroquina es un fármaco que puede producir disfunciones visuales, baja visión e incluso ceguera según la dosis. Una dosis acumulativa menor a 100 g de cloroquina, o una duración de tratamiento de menos de un año raramente se asocia con lesión retiniana. El riesgo de toxicidad aumenta cuando la dosis acumulativa excede los 300 g (250mg/día durante 3 años. Este medicamento es utilizado en el tratamiento de enfermedades autoinmunes. Se presenta una paciente de 44 años de edad, con antecedentes de artritis reumatoide hace 14 años para lo cual se indicó tratamiento con cloroquina (1 tableta 250 mg/diaria desde el diagnóstico inicial, y presenta un diagnóstico de maculopatía por cloroquina hace 5 años, a consulta por presentar baja visión y solicitando una posibilidad de rehabilitación visual. Se realizó examen oftalmológico, estudios complementarios y se rehabilitó mediante el microperímetro MP1. Se concluye que la maculopatía por cloroquina es una de las causas de discapacidad visual y que la rehabilitación visual con microperimetría proporciona mejoría en varios parámetros visuales, mejorando la calidad visual del paciente.

    2016-03-01

    Full Text Available La artritis reumatoide es una enfermedad de tipo autoinmune. Por su carácter altamente invalidante, requiere de manejo farmacológico agresivo. Para ello, habitualmente se hace necesario el uso de drogas inmunomoduladoras agrupadas bajo el nombre de fármacos antirreumáticos modificadores de la enfermedad. Uno de los utilizados con mayor frecuencia es la leflunomida, la cual por su mecanismo de acción es capaz de suprimir ejes fundamentales en el proceso de la enfermedad. Sin embargo, su uso no se encuentra exento de efectos secundarios. Si bien existen series que reportan que los efectos adversos más prevalentes son diarrea, náuseas, exantema y alopecia, existen escasos reportes de casos de alopecia areata universal secundaria al uso de leflunomida. A propósito de un caso en el Hospital Regional de Talca, se realizó una revisión de la literatura acerca del tema.

    Common variable immunodeficiency is the primary immunodeficiency (CVID) frequently found in adults. Its prevalence is estimated from 1:25,000 to 75,000 alive newborns; there are variations by ethnic groups, it is estimated about 50-70% in Caucasian patients. Oral cavity lesions are rarely found in adult patients with CVID, there are reports about lesions on pediatric patients mostly caused by infections. To describe the orofacial lesions (oral, maxillofacial and neck area) affecting adults with CVID. A transversal, prospective study was done in patients with CVID attended at Specialties Hospital, CMN SXXI, Mexico City. Patients where examined by the oral and maxillofacial surgeon and clinical findings were reported, then the descriptive analysis of the lesions was done. We evaluated 26 patients, 16 female and 10 males, average age of 38.6 years. In 18/26 patients we found oral lesions on 7 different types. The most frequent was minor salivary glands hiperplasia (19/26),petechiae (12/26) and herpetic ulcers (7/26). In head and neck, we found 4 different lesions, the most common was lymphadenopathy <2cm (4/26). The immunologic alterations associated to CVID favors the development of lesions mainly of infectious and probably autoinmune origin that affects the oral cavity and head and neck area.

    2013-04-01

    Full Text Available La ubicación anatómica de la glándula tiroidea y su biosíntesis hormonal están reguladas por la expresión de ciertos genes, cuya alteración puede conducir a las denominadas disgenesias tiroideas: agenesia, ectopía e hipoplasia, así como a las variantes dishormonogenéticas. Se presenta el caso de una paciente con retraso mental y diagnóstico de hipotiroidismo realizado en la edad adulta. Las determinaciones bioquímicas confirmaron el diagnóstico de hipotiroidismo no autoinmune. Este caso representa la evolución prolongada de una hipofunción tiroidea, que cursó en forma solapada y no diagnosticada durante 53 años de vida, con secuelas relevantes de esta deficiencia al momento del diagnóstico. La terapia exógena logró mejorías evidentes en la signo sintomatología, pero no revirtió el presunto daño neurológico atribuible a la falta de hormona tiroidea necesaria durante el desarrollo fetal. En la necropsia realizada se encontró escaso tejido tiroideo cervical correspondiente a hipoplasia tiroidea eutópica. El hallazgo de un remanente tiroideo menor a 1 cm permite explicar la supervivencia de la paciente hasta una edad avanzada.

    Full Text Available El sistema inmunológico es muy importante porque protege al organismo de agentes microbianos patógenos, toxinas, partículas extrañas, células tumorales y procesos autoinmunes. Para mantener el equilibrio biológico se necesita que este sistema funcione normalmente, de manera que constituya una fuerte barrera defensiva contra la invasión de agentes nocivos; de no suceder esto, se presentará una inmunodeficiencia de expresión clínica variable. La esencia de la función del sistema inmune es su gran capacidad para la discriminación a escala molecular entre lo propio y lo ajeno, o sea, lo que pertenece al organismo y lo que no, conservando así su individualidad.The immunological system is very important because it protects the organism from pathogenic microbial agents, toxins, foreign particles, tumoral cells and autoimmune processes. To maintain the biological balance, this system should work normally, acting as a strong defensive barrier against the invasion of harmful agents. Otherwise, there will be an immunodeficiency of variable clinical expression. The essence of the function of the immune system is its great capacity for distinguishing its own from the strange at the molecular level, that is, to recognize a difference between what belongs or not to the organism, keeping this way its individuality.

    2016-11-01

    Full Text Available Resumen La dermatomiositis es una miopatía inflamatoria autoinmune, asociada a manifestaciones dermatológicas. Su vinculación con neoplasias está ampliamente reportada, siendo más común en el cáncer pulmonar, especialmente en carcinoma de células pequeñas probablemente por su origen en precursores de células neuroendocrinas, así como también en cáncer de mama y ovario. La baja frecuencia de dermatomiositis dificulta la sospecha de las lesiones subyacentes entre las posibilidades diagnósticas de las enfermedades sistémicas con manifestaciones cutáneas. Por ello siempre se debe considerar la alta probabilidad de una neoplasia, con reportes de hasta 75% en la población oriental y cerca de 40% en general. En este artículo se presenta un caso poco frecuente de dermatomiositis con lesiones de distribución en chal, como debut sintomático de un carcinoma pulmonar de células pequeñas.

    Full Text Available Los glucocorticoides son usados comúnmente para el tratamiento de enfermedades inflamatorias, autoinmunes, enfermedades malignas, y en la prevención de rechazo de órganos trasplantados. Un efecto secundario frecuente del tratamiento prolongado es la pérdida de masa ósea que se produce por varios mecanismos y es causa de osteoporosis y fracturas vertebrales. El tratamiento con disfosfonatos ha sido propuesto para esta situación. Presentamos un caso clínico de osteoporosis grave en una niña con dermatomiositis juvenil, que respondió favorablemente al tratamiento con disfosfonatos orales.Glucocorticoids are used for the treatment of inflammatory and autoimmune diseases, cancer, and in prevention of organ rejects. A frequent secondary effect of longterm treatment with corticoids is the loss of bone mass, caused by several mechanisms: decrease in the intestinal calcium absorption, increase of the renal calcium excretion at the distal renal tubule, suppressive effect on the osteoblast and also in apoptosis of osteoclasts, inhibition in local production of IGF I (Insulin-like growth factor and IGFBPs (binding IGF I proteins necessary for bone metabolism, and decrease on osteocalcin production. Longterm treatment with corticoids is associated with osteoporosis and vertebral fractures. To improve this condition, treatment with bisphosphonates has been proposed. We present here a clinical case of a girl with dermatomyositis and severe osteoporosis with vertebral crushes, who responded well to oral bisphophonate treatment.

    Full Text Available El Síndrome de Sjögren (SS es una patología inflamatoria crónica, infradiagnosticada y de etiología desconocida, que se caracteriza por la infiltración linfocitaria de las glándulas exocrinas. La sintomatología puede ser muy variada. Inicialmente, lo más común es que se presente sequedad de mucosas (principalmente oculares y bucales; también se puede asociar a otras enfermedades autoinmunes, y hasta en el 65% de los casos, se pueden presentar manifestaciones extraglandulares, pudiéndose afectar cualquier parte del organismo. En muchos casos, la sintomatología inicial es leve, achacándose habitualmente a un posible disconfort en el puesto de trabajo. A esto hay que añadir que a nivel laboral no existe literatura específica en la que poder basarse para realizar una adecuada valoración médico-laboral. El objetivo de este trabajo ha sido crear una herramienta que englobe, por una parte, la vigilancia de la salud específica, y por otra, definir (aunque sea de forma orientativa, los criterios para poder realizar una correcta valoración de la capacidad laboral en los trabajadores con Síndrome de Sjögren.

    Alejandro Roque Valdés

    2004-04-01

    Full Text Available El presente trabajo es un artículo de revisión que pretende abordar un tema tan controvertido como actual: la posible asociación causal que se ha querido establecer entre el autismo y las vacunas infantiles. A partir de la última década del siglo XX se producen una serie de cambios en la clasificación, nomenclatura y criterios diagnósticos del autismo. Los hallazgos de estudios epidemiológicos llevados a cabo bajo estos nuevos ponderados han revelado que las tasas de prevalencia del autismo son en la actualidad muy superiores a las de hace 15 años. Entre los factores que se esgrimen para explicar este fenómeno están las vacunas, y entre los mecanismos que se invocan para tratar de inculpar a las vacunas en la etiología del autismo están el exceso de mercurio derivado del tiomersal que se emplea como conservante de las mismas y procesos autoinmunes que de forma directa o indirectamente actúan sobre el SNC, induciendo lesiones a nivel de la mucosa intestinal, lo cual favorecerá la absorción de macromoléculas, antígenos y toxinas que una vez en el torrente sanguíneo llegarían al SNC produciendo allí las lesiones responsables de la génesis del autismo.

    2013-06-01

    Full Text Available El síndrome hemofagocítico constituye una entidad infrecuente, heterogénea, subdiagnosticada, y muchas veces fatal. En los casos secundarios, los desencadenantes pueden ser numerosos, tales como infecciones, fármacos, enfermedades autoinmunes y neoplasias. El mecanismo fisiopatogénico se explica por la presencia de una función disminuida o defectuosa de células NK y linfocitos T citotóxicos, que resulta en una activación inmune inefectiva y descontrolada, conduciendo al daño celular, falla multiorgánica y proliferación macrofágica con hemofagocitosis. Existen diferentes opciones terapéuticas, mayormente combinaciones de citostáticos y esteroides, cuyo objetivo es la supresión de la respuesta inmune descontrolada. Ocasionalmente, la condición clínica de algunos pacientes con síndrome hemofagocítico impide la utilización de esquemas terapéuticos intensivos. Comunicamos el caso de un paciente quemado grave, que reúne los criterios diagnósticos de síndrome hemofagocítico, quien presentó una evolución favorable con el tratamiento combinado de esteroides e inmunoglobulinas endovenosas.

    Ivan Armando Osuna-Padilla

    2017-07-01

    Full Text Available La enfermedad renal crónica y el estado urémico se asocian con alteraciones en la permeabilidad intestinal y cambios en la microbiota intestinal, provocando una mayor producción y translocación de toxinas urémicas como sulfato de indoxilo (IS y sulfato de p-cresilo (pCS, detonando una respuesta inflamatoria. El estado inflamatorio y el incremento en concentraciones séricas de IS y pCS se han asociado con una mayor mortalidad, mayor número de eventos cardiovasculares y mayores alteraciones en el metabolismo mineral y óseo. Se han estudiado diversas estrategias nutricionales y farmacológicas para modular la microbiota intestinal y mejorar las alteraciones en la permeabilidad intestinal, entre ellas la suplementación con probióticos, prebióticos y simbióticos, modificaciones en la composición de la dieta y uso de agentes adsorbentes. El objetivo del presente trabajo es realizar una revisión de las causas de las alteraciones intestinales y de la microbiota intestinal en el paciente con enfermedad renal crónica, analizando las consecuencias de dichos cambios y las intervenciones estudiadas hasta la actualidad.

    2015-12-01

    Numerosos estudios apoyan la asociación de diversos marcadores inflamatorios con el estado cognitivo en esquizofrenia. El desarrollo de terapias eficaces en el rendimiento cognitivo se ha centrado en las últimas décadas en la búsqueda de fármacos inmunomoduladores o antiinflamatorios. Por otro lado, se ha demostrado la implicación de la prolactina y su función en la cognición y transición a la psicosis, así como en el pronóstico y diagnóstico de la esquizofrenia con independencia del tratamiento antipsicótico. En cuanto a factores neurotróficos, un estudio reciente correlaciona los niveles de BDNF con la mejoría cognitiva en pacientes diagnosticados de esquizofrenia tratados con rehabilitación cognitiva. Concluimos que, a pesar de la diversidad de biomarcadores asociados con el estado cognitivo en esquizofrenia, el BDNF es el biomarcador que acumula mayor evidencia en la literatura científica actual.

Los animales eran serologicamente negativos para N.caninum y T. gondii. Dos ovejas gestantes, noinoculadas, fueron utilizadas como control negativo. Los corderos necropsiados, nacidos de ovejas inoculadasantes o durante la gestación presentaron alteraciones histopatológicas en diferentes tejidos, siendo las masseveras observadas en el sistema nervioso central, caracterizadas por la presencia de formas quísticas delparásito asociadas con infiltrado inflamatorio predominantemente mononuclear, áreas de necrosis y en algunoscasos presencia de calcificación. Los corderos nacidos de ovejas inoculadas 10 días después del parto nopresentaron signos clínicos de la enfermedad ni anticuerpos contra o parásito y a la necropsia no presentaronlesiones en ninguno de los tejidos analizados. Un cordero nacido de oveja no inoculada no presentó alteracionesmicroscópicas en ninguno de los tejidos analizados

    Full Text Available La aterosclerosis se considera como la principal causante de enfermedades cardiovasculares. Es una enfermedad multifactorial, caracterizada por procesos inflamatorios y la internalización continua de moléculas lipídicas al interior del vaso. Los estudios de genes candidato han proporcionado conocimiento acerca de la fisiopatología de esta enfermedad y han permitido la postulación de algunos polimorfismos como responsables de la susceptibilidad genética en diversas poblaciones. En particular, estos polimorfismos que modulan ciertas vías moleculares tales como el estrés oxidativo, el metabolismo lipídico y la trombogénesis se asocian con el desarrollo de las enfermedades cardiovasculares. Se han conducido varios estudios para identificar nuevas variantes asociadas con la enfermedad que han permitido el descubrimiento de nuevas vías de la enfermedad. Aunque el hallazgo de nuevos genes asociados a la enfermedad cardiovascular a través de enfoques como el escaneo global del genoma ha contribuido al entendimiento del desarrollo de esta condición, el conocimiento aún es limitado y poco concluyente. El objetivo de esta revisión es identificar los genes y las variantes polimórficas asociadas a la enfermedad cardiovascular, de acuerdo con los diferentes enfoques de análisis de asociación genética.

    Full Text Available La actividad antiinflamatoria suscita gran interés científico en el área farmacológica, debido a que muchas enfermedades en su evolución cursan por procesos inflamatorios (artritis reumatoide, ateroesclerosis, cáncer, diabetes, gota, asma, dermatitis, trastornos neurodegenerativos y diversas dolencias menores. Las enfermedades inflamatorias constituyen un problema de salud importante, debido a la falta de medicamentos eficaces y seguros para su uso por periodos prolongados. Hoy en día se trabaja en la búsqueda de alternativas de antiinflamatorios más seguros, en el que las plantas medicinales, una de las formas más antiguas de tratamiento, constituyen una elección a considerar. En este trabajo se realizó una revisión bibliográfica, sobre especies de plantas que crecen en Cuba que le reportan propiedades farmacológicas como antinflamatorios. En la revisión de la literatura se utilizó la base de datos Medline (vía PubMed, así como revistas nacionales desde el periodo de 2000 hasta el presente, con las palabras claves "inflamación" y "plantas cubanas antiinflamatorias" o "actividad antiinflamatoria" y "plantas medicinales".
