  1. AIDS: acquired immunodeficiency syndrome

    Gilmore, N. J.; Beaulieu, R.; Steben, M.; Laverdière, M.

    2002-01-01

    Acquired immunodeficiency syndrome, or AIDS, is a new illness that occurs in previously healthy individuals. It is characterized by immunodeficiency, opportunistic infections and unusual malignant diseases. Life-threatening single or multiple infections with viruses, mycobacteria, fungi or protozoa are common. A rare neoplasm, Kaposi's sarcoma, has developed in approximately one third of patients with AIDS. More than 800 cases of AIDS have been reported in North America, over 24 of them in Ca...

    @@ Acquired von Willebrand syndrome (AvWS) is kind of bleeding disorder with laboratory findings similar to those in congenital yon Willebrand disease (vWD).AvWS doesn's have any personal or family history of bleeding, but is associated with certain diseases or abnormal conditions or drugs. Although AvWS is being stated as a rare disease, it has gained more and more attention during the past years. Not because of the severity of the disease, but it is more common than we thought and most patients don' t have a proper diagnosis.

  3. The Acquired Immunodeficiency Syndrome: current status.

    Quagliarello, V.

    1982-01-01

    A recently recognized syndrome of acquired immunodeficiency (Acquired Immunodeficiency Syndrome-AIDS) has arisen since June 1981. It has received international attention. The clinical spectrum consists of repeated opportunistic infections, rare malignancies, and autoimmune phenomena, occurring in previously healthy adults with no history of an immunologic disorder. The population subset at risk for this syndrome appears to be predominantly homosexual American males and intravenous drug abuser...

  4. Immunological memory and acquired immunodeficiency syndrome pathogenesis.

    Kaur, A; Rosenzweig, M; Johnson, R. P.

    2000-01-01

    Infection with the human immunodeficiency virus results in profound perturbations in immunological memory, ultimately resulting in increased susceptibility to opportunistic infections and acquired immunodeficiency syndrome (AIDS). We have used rhesus macaques infected with the simian immunodeficiency virus (SIV) as a model to understand better the effects of AIDS virus infection on immunological memory. Acute infection with SIV resulted in significant deficits in CD4+ helper responses to cyto...

Specific aspects of infection with human immunodeficiency virus (HIV) and acquired immunodeficiency syndrome (AIDS) that relate to physicians' ethical responsibilities as well as society's moral obligations are discussed. Such matters include the need for education, research and treatment resources; the patient's right to investigation and treatment and to refusal of eith...

  6. The acquired immunodeficiency syndrome in gay men.

    Jaffe, H W; Hardy, A M; Morgan, W M; Darrow, W W

    1985-11-01

    The acquired immunodeficiency syndrome (AIDS) is a major health problem for gay men in the United States. About three fourths of all reported cases have occurred in this population, and the number is projected to double in the next year. In Manhattan and San Francisco, AIDS is now the leading cause of premature mortality in men aged 25 to 44 years who have never married. In a sample of a cohort of gay men enrolled in a San Francisco clinic, 2.7% of the men had the syndrome and 26% had related conditions in 1984. Antibody to human T-lymphotropic virus, type III/lymphadenopathy-associated virus was found in sera from 67% of the men, including 58% of asymptomatic men. Behavioral factors associated with an increased risk of AIDS include large numbers of sexual partners, receptive anal intercourse, and "fisting." The adoption of safer lifestyles is currently the basis of attempts to control the syndrome in gay men. PMID:2996396

  7. [Acquired immunodeficiency syndrome in pediatric patients].

    Molina Moguel, J L; Ruiz Illezcas, R; Forsbach Sánchez, S; Carreño Alvarez, S; Picco Díaz, I

    1990-12-01

    The object of this study was to determine how many of the patients treated at the Pediatric Odontology Clinic, a branch of the Maxillo-Facial Surgery Service at the Veinte de Noviembre Regional Hospital, ISSSTE, are VIH-positive of show serious manifestations of Acquired Immuno-Deficiency Syndrome (AIDS). For such purpose, 100 pediatric patients suffering from different systemic or local diseases were evaluated, the most common being hematological alterations. Results evidenced the presence of VIH in the blood of five of the pediatric subjects, all suffering from Hemophilia. PMID:2132469

  8. Cerebral involvement in acquired immunodeficiency syndrome (AIDS)

    Involvement of the central nervous system in acquired immune deficiency syndrome (AIDS) is usually due to opportunistic infections; these frequently offer a difficult differential diagnostic problem. Imaging methods play an important part in the elucidation of symptoms. CT and MR findings were analysed in 13 patients with AIDS and neurological symptoms. Some infections of the central nervous system (encephalitis of unknown aetiology, cytomegalic encephalitis, meningitis) may show cerebral atrophy or even no morphological changes. Toxoplasmosis and PML are the most common opportunistic infections typical changes on CT and MR may lead to diagnosis. MR offers advantages compared with CT in its higher sensitivity for the demonstration even of small lesions. (orig.)

  11. The acquired hyperostosis syndrome. Pt. 2

    In the second part of this publication, we describe some additional findings in cases of sternocostoclavicular hyperostosis (SCCH). These include focal hyperostosis of the spine, in the pelvis and in the extremities and psoriatric skin lesions and severe forms of acne (acne conglobata, acne fulminans). An analysis of our 13 patients and of the relevant literature indicates that the hyperostosis is due to increased bone metabolism and heterotopic ossification of fibrous tissue and that these are the pathogenic bases of the changes in the axial skeleton, the pelvis and the bones of the extremities. We have suggested a scheme which would categorise the syndrom into complete, incomplete and possibly acquired forms. (orig./GDG)

    Background Cytomegalovirus (CMV) retinitis is the most severe intraocular complication that results in total retinal destruction and loss of visual acuity in patients with acquired immunodeficiency syndrome (AIDS). This study aimed to investigate the fundus characteristics, systemic manifestations and therapeutic outcomes of CMV retinitis associated with AIDS.Methods It was a retrospective case series. CMV retinitis was present in 39 eyes (25 patients). Best corrected visual acuities, anterior segment, fundus features, fundus fluorescence angiography (FFA) and CD4+ T-lymphocyte counts of the patients with CMV retinitis associated with AIDS were analyzed. Intravitreal injections of ganciclovir (400 μg) were performed in 4 eyes (2 patients).Results Retinal vasculitis, dense, full-thickness, yellow-white lesions along vascular distribution with irregular granules at the border, and hemorrhage on the retinal surface were present in 28 eyes. The vitreous was clear or mildly opaque.Late stage of the retinopathy was demonstrated in 8 eyes characterized as atrophic retina, sclerotic and attenuated vessels, retinal pigment epithelium (RPE) atrophy, and optic nerve atrophy. Retinal detachment was found in 3 eyes. The average CD4+ T-lymphocyte count in peripheral blood of the patients with CMV retinitis was (30.6±25.3) ×106/L (range,(0-85) × 106/L). After intravitreal injections of ganciclovir, visual acuity was improved and fundus lesions regressed.Conclusions CMV retinitis is the most severe and the most common intraocular complication in patients with AIDS. For the patients with yellow-white retinal lesions, hemorrhage and retinal vasculitis without clear cause, human immunodeficiency virus (HIV) serology should be performed. Routine eye examination is also indicated in HIV positive patients.

  18. Tuberculosis and the acquired immune deficiency syndrome in South Brazil

    Tuberculosis and the acquired immune deficiency syndrome in South Brazil. The authors studied the incidence of tuberculosis in South Brazilian patients with acquired immune deficiency syndrome from January 1985 to June 1988. During this period, tuberculosis occurred in 10.3% of acquired immune deficiency syndrome patients. The socioeconomic conditions and the incidence of disease in the population were not confirmed as a potential risk for tuberculosis infection. Chest radiographs revealed pulmonary infiltrates in six patients, hilar and/or mediastinal adenopathy in three, and pleural effusion in two. The two remaining patients had pulmonary consolidation associated with other features. None of these patients presented pulmonary cavitation or radiographic findings of typical reactivation of pulmonary tuberculosis. (author)

    2012-01-01

    Full Text Available Brown-Sequard syndrome is commonly seen in the setting of spinal trauma or an extramedullary spinal neoplasm. The clinical picture reflects hemisection of the spinal cord. We report a rare case of Brown-Sequard syndrome caused by a large cervical herniated disc. A 63-year-old man presented with progressive right hemiparesis and disruption of pain and temperature sensation on the left side of the body. Magnetic resonance imaging showed large C3-C4 disc herniation compressing the spinal cord at that level, with severe canal stenosis from C4 through C7. Decompressive cervical laminoplasty was performed. After surgery, complete sensory function was restored and a marked improvement in motor power was obtained.

  20. Hemorrhagic abscess in a patient with the acquired immunodeficiency syndrome

    A 53-year-old white man had fever, malaise, and dyspnea on exertion. His chest roentgenogram was normal, but pulmonary function tests showed impaired diffusion capacity and a gallium scan showed marked uptake in the lungs. Results of an open-lung biopsy documented Pneumocystis carinii pneumonia. Immunologic test results were consistent with the acquired immunodeficiency syndrome. The patient denied having homosexual contact or using intravenous drugs. Twenty-nine months before the diagnosis of pneumocystis pneumonia was made, the patient had had 16 transfusions of whole blood, platelets, and fresh-frozen plasma during coronary artery bypass surgery at another medical center. This patient is not a member of any currently recognized high-risk group and is believed to have contracted the acquired immunodeficiency syndrome from blood and blood-product transfusions.

    @@ The spectrum of cancers seen in human immunodeficiency virus (HIV)infected individuals is diverse and complex,and reflects an ever-changing HIV epidemic.In parts of the world where combination antiretroviral therapy (cART) is available,HIV-infected patients are living longer and are less likely to die of acquired immunodeficiency syndrome (AIDS)defining malignancies within a year or two of developing AIDS.

  5. Cerebral computed tomography in men with acquired immunodeficiency syndrome

    Brun, B.; Boesen, F.; Gerstoft, J.; Nielsen, J.O.; Praestholm, J.

    Cerebral CT scannings were performed in 19 homosexual men with the acquired immunodeficiency syndrome (AIDS). Nearly half of them (9 patients) had cortical atrophy. Three patients with toxoplasmosis had cerebral pathology, in two of them with ring enhancement while the third had an ill-defined nonspecific lesion with slight heterogeneous enhancement without ring formation. Two patients with multifocal leucoencephalopathy and non-Hodgkin's lymphoma, respectively, presented non-enhancing, low attenuating lesions at CT.

    2013-10-01

    Full Text Available A 89-year-old man with a history of cataract surgery ten years ago presented to our ophthalmology department with blurred vision. On ophthalmic examination, best-corrected visual acuity was 20/50 in the right eye and 20/32 in the left. Slit lamp examination revealed bilateral symmetrical peripheral corneal oedema, advanced at the inferior part of the cornea in both eyes. Considering clinical and confocal microscopy findings, a diagnosis of Brown-McLean Syndrome (BMS was made. BMS is a rare condition that may developed after cataract surgery, and it can be easily overlooked or misdiagnosed. Our report points to this rare syndrome and we tried to emphasis the importance of BMS considering it in the differential diagnosis of refractory peripheral corneal oedema developed in pseudophakic patients.

    2004-01-01

    Full Text Available Acute febrile neutrophilic dermatosis (AFND, commonly known as Sweet’s syndrome, is a disorder seen in adult females, being extremely rare in children. Typical features include spiky fever, sudden eruption of raised painful erythematous to plum-colored nodules and plaques, neutrophilic leucocytosis, a dermal neutrophili infiltrate an a rapid response to systemic steroid. The eruption is believed to represent a hypersensitivity reaction to an antecedent infection or malignancy. There have been rare reports of acquired cutis laxa (Marshall’s syndrome following Sweet’s syndrome. We report one such case of Sweet’s syndrome leading to acquired cutis laxa (Marshall’ syndrome in a child.

  10. Anthracyclines and Acquired Long QT Syndrome. A Case Report

    Carlos Rodríguez Armada

    2014-12-01

    Full Text Available Acquired long QT syndrome results from secondary causes and can be caused by more than 100 non-antiarrhythmic drugs. Cardiac arrest due to Torsades de pointes induced by drugs causing prolonged QT syndrome is a rare but potentially fatal event, even in hospitals. The case of a 47-year-old patient diagnosed with non-Hodgkin lymphoma admitted to the hematology department of the Dr. Gustavo Aldereguía Lima University General Hospital in Cienfuegos is presented. The patient had been previously treated with anthracyclines and developed episodes of palpitations and syncope later. The treatment included monitoring the patient, avoiding other QT prolonging agents and administrating magnesium sulfate and potassium chloride with a proper maintenance of the fluid and acid-base balance. The presentation of this case aims at motivating interest in new reports on the subject and establishing a direct causal relationship through the evidence provided by new experiences.

    2014-04-01

    Acquired long QT syndrome (LQTS) is a disorder of cardiac repolarization most often due to specific drugs, hypokalemia, or hypomagnesemia that may precipitate torsade de pointes and cause sudden cardiac death. Common presentations of the LQTS are palpitations, presyncope, syncope, cardiac arrest, and seizures. An abnormal 12-lead electrocardiogram obtained while the patient is at rest is the key to diagnosis. The occurrence of drug-induced LQTS is unpredictable in any given individual, but a common observation is that most patients have at least 1 identifiable risk factor in addition to drug exposure. The cornerstone of the management of acquired LQTS includes the identification and discontinuation of any precipitating drug and the correction of metabolic abnormalities, such as hypokalemia or hypomagnesemia. Most of the episodes of torsade de pointes are short-lived and terminate spontaneously. We propose a management protocol that could be useful for the daily practice in the emergency pediatric department to reduce the risk of acquired QT prolongation. PMID:24694881

    Full Text Available Brown-Séquard's syndrome (BSS is caused by hemisection or hemicompression of the cord leading to ipsilateral motor deficit and contralateral sensory loss. Cervical disc herniation has been reported to be a rare cause of Brown-Séquard's syndrome. We describe a rare case of multilevel cervical disc herniation presenting as BSS. The condition was confirmed by MRI scan. Cervical corpectomy, decompression, and fusion gave a satisfying result. Pertinent literature has been reviewed.

  14. Cerebral toxoplasmosis and lymphoma in patients with Acquired Immunodeficiency Syndrome

    Toxoplasmosis now constitutes a relatively frequent central nervous system (CNS) complication of AIDS, primary CNS lymphoma being far less common. CT scanning using the double-dose delayed (D-D-D) scan technique has proved an effective way of helping in the diagnosis of these complications. 16 patients with CNS complications of the acquired immunodeficiency syndrome (AIDS) are described. All patients were male homosexuals. The most common demonstrable lesion in the parenchyma was toxoplasmosis, which produced an area of focal oedema, usually containing a central zone of nodular or ring-shaped enhancement. Cerebral atrophy was also a common finding. One patient had diffuse peri-ventricular lymphomatous infiltration, and a further two patients had both cerebral toxoplasmosis and lymphoma. A delayed double dose contrast examination appears to be the most accurate method of outlining the total extent of CNS disease in these patients. 11 refs., 7 figs., 2 tabs

  15. Brain CT in pediatric patients with acquired immunodeficiency syndrome

    Review of the cranial Ct scans of 28 infants and children with acquired immunodeficiency syndrome revealed that cerebral atrophy was the most common finding, occurring in 19 patients. Next most common was basal ganglionic calcification, present in 11 patients without the usual biochemical abnormalities associated with this finding. In ten patients varying degrees of abnormally low attenuation were seen in the white matter. In contrast to the situation in adults, there were no examples of mass lesions due to opportunistic infections. Pathologic specimens were available in eight patients. These confirmed the presence of calcific vasculopathy in four patients with basal ganglionic calcification on CT and showed calcification in an additional four patients. Other findings included glial nodules, tract degeneration, and white matter pallor

  16. Bronchogenic carcinoma in acquired immunodeficiency syndrome - report of two cases

    The authors report two cases of bronchogenic carcinoma in patients with acquired immunodeficiency syndrome. The first patient, a ee-year-old male, developed a left hilar adenocarcinoma, with spleen and bilateral adrenal metastases. The disease progressed unfavourably, resulting in the patient's death in less than a month. The second patient, a 47-year-old male, developed a large mass in the left upper lobe, with invasion of the thoracic wall and destruction of adjacent ribs. The histopathologic study revealed a non-oat-cell carcinoma. Both patients received palliative treatment since diagnosis was established late in the course of the disease. Recent studies suggest an association between bronchogenic carcinoma and human immunodeficiency virus infection. However, an actual increase in the prevalence of bronchogenic carcinoma in HIV-positive patients remains controversial. (author)

  17. Management of Diabetes Mellitus in Patients with Acquired Immunodeficiency Syndrome

    Miulescu Rucsandra Dănciulescu

    2014-06-01

    Full Text Available Acquired immunodeficiency syndrome (AIDS is a human immune system disease characterized by increased susceptibility to opportunistic infections, certain cancers and neurological disorders. The syndrome is caused by the human immunodeficiency virus (HIV that is transmitted through blood or blood products, sexual contact or contaminated hypodermic needles. Antiretroviral treatment reduces the mortality and the morbidity of HIV infection but is increasingly reported to be associated with increasing reports of metabolic abnormalities. The prevalence and incidence of diabetes mellitus in patients on antiretroviral therapy is high. Recently, a joint panel of American Diabetes Association (ADA and European Association for the Study of Diabetes (EASD experts updated the treatment recommendations for type 2 diabetes (T2DM in a consensus statement which provides guidance to health care providers. The ADA and EASD consensus statement concur that intervention in T2DM should be early, intensive, and uncompromisingly focused on maintaining glycemic levels as close as possible to the nondiabetic range. Intensive glucose management has been shown to reduce microvascular complications of diabetes but no significant benefits on cardiovascular diseases. Patients with diabetes have a high risk for cardiovascular disease and the treatment of diabetes should emphasize reduction of the cardiovascular factors risk. The treatment of diabetes mellitus in AIDS patients often involves polypharmacy, which increases the risk of suboptimal adherence

    Full Text Available Acquired von Willebrand syndrome (AVWS is an uncommon, underdiagnosed, and heterogeneous disease which is increasingly recognized as a cause of bleeding diatheses. Systemic lupus erythematosus (SLE is an infrequent cause of AVWS. Herein, we report a case of AVWS diagnosed during the initial presentation of SLE in a previously healthy young man with no family history of bleeding diathesis who presented with worsening epistaxis, gastrointestinal bleeding, and anasarca. He was found to have severe anemia and prolonged activated partial thromboplastin time (aPTT with severely decreased levels of von Willebrand factor (VWF measurements in addition to markedly decreased factor VIII levels. Further evaluation revealed nephrotic syndrome and interstitial lung disease due to SLE. He initially received combination therapy with intravenous immunoglobulin (IVIG and von Willebrand factor/factor VIII concentrates without significant improvement. Treatment with steroids, cyclophosphamide, and rituximab was followed by clinical improvement evidenced by cessation of bleeding. The short follow-up did not allow us to definitely prove the therapeutic effect of immunosuppressive treatment on AVWS in SLE patients. This case adds to the literature supporting the relationship between AVWS and SLE and highlights the importance of combination therapy in the treatment of severe AVWS as well as the role of IVIG, cyclophosphamide, and rituximab in AVWS associated with SLE.

    Polycystic ovary syndrome (PCOS), which is characterized by anovulation, hyperandrogenism, and polycystic ovaries, is a complex endocrinopathy. Because the cause of PCOS at the molecular level is largely unknown, there is no cure or specific treatment for PCOS. Here, we show that transplantation of brown adipose tissue (BAT) reversed anovulation, hyperandrogenism, and polycystic ovaries in a dehydroepiandrosterone (DHEA)-induced PCOS rat. BAT transplantation into a PCOS rat significantly stabilized menstrual irregularity and improved systemic insulin sensitivity up to a normal level, which was not shown in a sham-operated or muscle-transplanted PCOS rat. Moreover, BAT transplantation, not sham operation or muscle transplantation, surprisingly improved fertility in PCOS rats. Interestingly, BAT transplantation activated endogenous BAT and thereby increased the circulating level of adiponectin, which plays a prominent role in whole-body energy metabolism and ovarian physiology. Consistent with BAT transplantation, administration of adiponectin protein dramatically rescued DHEA-induced PCOS phenotypes. These results highlight that endogenous BAT activity is closely related to the development of PCOS phenotypes and that BAT activation might be a promising therapeutic option for the treatment of PCOS.

  20. Radionuclide brain imaging in acquired immunodeficiency syndrome (AIDS)

    Infection with the Human Immunodeficiency Virus type 1 (HIV-1) may produce a variety of central nervous system (CNS) symptoms and signs. CNS involvement in patients with the Acquired Immunodeficiency Syndrome (AIDS) includes AIDS dementia complex or HIV-1 associated cognitive/motor complex (widely known as HIV encephalopathy), progressive multifocal leucoencephalopathy (PML), opportunistic infections such as Toxoplasma gondii, TB, Cryptococcus and infiltration by non-Hodgkin's B cell lymphoma. High resolution structural imaging investigations, either X-ray Computed Tomography (CT scan) or Magnetic Resonance Imaging (MRI) have contributed to the understanding and definition of cerebral damage caused by HIV encephalopathy. Atrophy and mainly high signal scattered white matter abnormalities are commonly seen with MRI. PML produces focal white matter high signal abnormalities due to multiple foci of demyelination. However, using structural imaging techniques there are no reliable parameters to distinguish focal lesions due to opportunistic infection (Toxoplasma gondii abscess) from neoplasm (lymphoma infiltration). It is studied the use of radionuclide brain imaging techniques in the investigation of HIV infected patients. Brain perfusion Single Photon Emission Tomography (SPET), neuroreceptor and Positron Emission Tomography (PET) studies are reviewed. Greater emphasis is put on the potential of some radiopharmaceuticals, considered to be brain tumour markers, to distinguish intracerebral lymphoma infiltration from Toxoplasma infection. SPET with 201Tl using quantification (tumour to non-tumour radioactivity ratios) appears a very promising technique to identify intracerebral lymphoma

    Acquired immunodeficiency syndrome (AIDS) remains ill-defined by lists of symptoms, infections, tumors, and disorders in metabolism and immunity. Low CD4 cell count, severe loss of body weight, pneumocystis pneumonia, and Kaposi's sarcoma are the major disease indicators. Lines of evidence indicate that patients living with AIDS have both immunodeficiency and autoimmunity. Immunodeficiency is attributed to deficits in the skin- and mucosa-defined innate immunity, CD4 T cells and regulatory T cells, presumably relating human immunodeficiency virus (HIV) infection. The autoimmunity in AIDS is evident by: (1) overproduction of autoantibodies, (2) impaired response of CD4 cells and CD8 cells, (3) failure of clinical trials of HIV vaccines, and (4) therapeutic benefits of immunosuppression following solid organ transplantation and bone marrow transplantation in patients at risk of AIDS. Autoantibodies are generated in response to antigens such as debris and molecules de novo released from dead cells, infectious agents, and catabolic events. Disturbances in metabolic homeostasis occur at the interface of immunodeficiency and autoimmunity in the development of AIDS. Optimal treatments favor therapeutics targeting on the regulation of metabolism to restore immune homeostasis. PMID:26676359

  2. An Increased Risk of Osteoporosis during Acquired Immunodeficiency Syndrome

    2004-08-01

    Full Text Available Osteoporosis is characterized by decreased bone mineral density and mechanistic imbalances of bone tissue that may result in reduced skeletal strength and an enhanced susceptibility to fractures. Osteoporosis in its most common form affects the elderly (both sexes and all racial groups of human beings. Multiple environmental risk factors like acquired immune deficiency syndrome (AIDS are believed to be one of the causes of osteoporosis. Recently a high incidence of osteoporosis has been observed in human immunodeficiency virus (HIV infected individuals. The etiology of this occurrence in HIV infections is controversial. This problem seems to be more frequent in patients receiving potent antiretroviral therapy. In AIDS, the main suggested risk factors for the development of osteoporosis are use of protease inhibitors, longer duration of HIV infection, lower body weight before antiretroviral therapy, high viral load. Variations in serum parameters like osteocalcin, c-telopeptide, levels of elements like Calcium, Magnesium, Phosphorus, concentration of vitamin-D metabolites, lactate levels, bicarbonate concentrations, amount of alkaline phosphatase are demonstrated in the course of development of osteoporosis. OPG/RANKL/RANK system is final mediator of bone remodeling. Bone mineral density (BMD test is of added value to assess the risk of osteoporosis in patients infected with AIDS. The biochemical markers also aid in this assessment. Clinical management mostly follows the lines of treatment of osteoporosis and osteopenia.

  3. Computed tomography of the lungs in acquired immunodeficiency syndrome

    Computed tomography of the chest was performed on 42 occasions as part of the diagnostic work-up in 26 homosexual men with, or suspected of the acquired immunodeficiency syndrome (AIDS). In 17 cases both the chest radiographs and the lung scans were abnormal, and bronchoscopy and/or lung biopsy established an etiologic diagnosis in the majority of these cases. In 9 cases CT of the lungs revealed unequivocal interstitial infiltration in the presence of a normal chest radiography, and subsequently and etiologic agent was demonstrated in all these cases. In 9 cases, patients with symptoms indicative of pulmonary infection had both a normal chest radiograph and a normal lung scan, and in none of these cases did the clinical course or additional diagnostic procedures indicate the presence of current opportunistic lung infection. CT of the lungs seems to identify accurately those patients with severe HIV-related diseases in whom invasive diagnostic procedures such as bronchoalveolar lavage and/or lung biopsy should be done.

    1995-09-01

    Infection with the Human Immunodeficiency Virus type 1 (HIV-1) may produce a variety of central nervous system (CNS) symptoms and signs. CNS involvement in patients with the Acquired Immunodeficiency Syndrome (AIDS) includes AIDS dementia complex or HIV-1 associated cognitive/motor complex (widely known as HIV encephalopathy), progressive multifocal leucoencephalopathy (PML), opportunistic infections such as Toxoplasma gondii, TB, Cryptococcus and infiltration by non-Hodgkin`s B cell lymphoma. High resolution structural imaging investigations, either X-ray Computed Tomography (CT scan) or Magnetic Resonance Imaging (MRI) have contributed to the understanding and definition of cerebral damage caused by HIV encephalopathy. Atrophy and mainly high signal scattered white matter abnormalities are commonly seen with MRI. PML produces focal white matter high signal abnormalities due to multiple foci of demyelination. However, using structural imaging techniques there are no reliable parameters to distinguish focal lesions due to opportunistic infection (Toxoplasma gondii abscess) from neoplasm (lymphoma infiltration). It is studied the use of radionuclide brain imaging techniques in the investigation of HIV infected patients. Brain perfusion Single Photon Emission Tomography (SPET), neuroreceptor and Positron Emission Tomography (PET) studies are reviewed. Greater emphasis is put on the potential of some radiopharmaceuticals, considered to be brain tumour markers, to distinguish intracerebral lymphoma infiltration from Toxoplasma infection. SPET with {sup 201}Tl using quantification (tumour to non-tumour radioactivity ratios) appears a very promising technique to identify intracerebral lymphoma.

  6. Kaposi sarcoma and lymphadenopathy syndrome: limitations of abdominal CT in acquired immunodeficiency syndrome

    Moon, K.L. Jr.; Federle, M.P.; Abrams, D.I.; Volberding, P.; Lewis, B.J.

    1984-02-01

    Abdominal computed tomography (CT) was performed in 31 patients with Kaposi sarcoma (KS) related to acquired immunodeficiency syndrome (AIDS), three patients with classic KS, and 12 patients with the newly described lymphadenopathy syndrome (LNS). The frequency, distribution, and appearance of lymphadenopathy and splenomegaly were similar in the AIDS-related KS and LNS groups. Rectal and perirectal disease was identified in 86% of homosexual men studied; rectal KS could not be distinguished from proctitis on CT criteria alone. No CT abnormalities were seen in patients with classic KS. The CT demonstration of retroperitoneal, mesenteric, or pelvic adenopathy or of rectal or perirectal disease in patients with AIDS-related KS is not necessarily indicative of widespread involvement with the disease.

  8. Intramedullary spinal cord metastasis from colonic carcinoma presenting as Brown-Sequard syndrome: a case report

    Kaballo, Mohammed A

    2011-08-02

    Abstract Introduction Intramedullary spinal cord metastasis is very rare. The majority are discovered incidentally during autopsy. Most symptomatic patients present with rapidly progressive neurological deficits and require immediate examination. Few patients demonstrate features of Brown-Séquard syndrome. Radiotherapy is the gold-standard of therapy for Intramedullary spinal cord metastasis. The overall prognosis is poor and the mortality rate is very high. We present what is, to the best of our knowledge, the first case of Intramedullary spinal cord metastasis of colorectal carcinoma presenting as Brown-Séquard syndrome. Case presentation We present the case of a 71-year-old Caucasian man with colonic adenocarcinoma who developed Intramedullary spinal cord metastasis and showed features of Brown-Séquard syndrome, which is an uncommon presentation of Intramedullary spinal cord metastasis. Conclusion This patient had an Intramedullary spinal cord metastasis, a rare form of metastatic disease, secondary to colonic carcinoma. The metastasis manifested clinically as Brown-Séquard syndrome, itself a very uncommon condition. This syndrome is rarely caused by intramedullary tumors. This unique case has particular interest in medicine, especially for the specialties of medical, surgical and radiation oncology. We hope that it will add more information to the literature about these entities.

    Full Text Available Abstract Background PHACE is a neurocutaneous syndrome associated with: Posterior fossa brain malformations, large “segmental” facial hemangiomas, arterial cerebrovascular-, cardiovascular-, and eye anomalies. Case vignette We are reporting a girl with PHACE syndrome. The patient had a congenital right-sided facial hemangioma with plaque-morphology. At age 11 years and 2 months she presented with short stature, markedly decreased growth velocity and signs and symptoms suggestive of hypothyroidism. Magnetic Resonance Imaging (MRI of the brain revealed complex structural and cerebrovascular arterial anomalies, including an empty sella. Testing of pituitary function revealed multiple pituitary dysfunctions, including absolute growth hormone deficiency, hypogonadotropic hypogonadism, central hypothyroidism, and secondary adrenal insufficiency. Conclusions This case suggests the necessity to screen all patients with PHACE syndrome and intracranial malformations for pituitary dysfunction at regular intervals.

  12. Tatton-Brown-Rahman syndrome due to 2p23 microdeletion.

    Okamoto, Nobuhiko; Toribe, Yasuhisa; Shimojima, Keiko; Yamamoto, Toshiyuki

    2016-05-01

    Tatton-Brown-Rahman syndrome is a new overgrowth syndrome due to DNMT3A (DNA cytosine 5 methyltransferase 3A) mutations. Mutation carriers show a distinctive facial appearance, intellectual disability, and increased height. We report a patient with overgrowth who showed submicroscopic deletion of chromosome 2p23 including DNMT3A. The deletion was detected by array-CGH. He showed moderate ID and distinctive facial gestalt. His clinical features were consistent with those of Tatton-Brown-Rahman syndrome. We suggest that 2p23 microdeletion including DNMT3A may cause similar symptoms in patients with DNMT3A mutations and should be considered in patients with overgrowth. © 2016 Wiley Periodicals, Inc.

    Full Text Available The association of Reiter's Syndrome (RS with the Acquired Immunodeficiency Syndrome (AIDS is seldom mentioned in the medical literature. This report illustrates this relationship in a 46 years old male patient suffering from AIDS (CD4+ = 240 cells/mm³, CD8+ = 1,301 cells/mm³ and viral load = 330,000 copies/ml, pulmonary tuberculosis (positive catarrhal bacilluscopy, and RS. The diagnosis of RS was based on the combination of dermatological and articular alterations. The patient's cutaneous lesions were characterized by exfoliation and the formation of crusts located on the face, scalp, genitals, hands, and feet; onychodystrophy with opacity; yellowish coloring; and hyperkeratosis of the nails. Articular lesions led to progressive deformity of phalangeal joints of the hands, and intensive arthralgia, mainly of the larger joints (shoulders, elbows, hips and knees. AIDS treatment was administered with anti-retroviral drugs (zidovudine and didanosine; for tuberculosis (isoniazid, rifampicine, and pyrazinamide; and (prednisone and inometacine for the RS. The patient recovered with the improvement of articular symptoms; however, on the eighth day of treatment, the patient showed significant hemoptysis and hypovolemic shock, and died. The association of RS and HIV infection is reviewed.

    Jose, Sheethal K; Marfatia, Yogesh S

    2016-01-01

    A 47-year-old male with acquired immune deficiency syndrome (AIDS) presented with multiple hyperpigmented papules and nodules on both ankles, dorsum of bilateral feet and soles. It was associated with mild itching and pain. The patient was diagnosed with human immunodeficiency virus (HIV) in 2007. First-line antiretroviral therapy (ART) was started in 2009 to which he responded initially. He was shifted to second-line ART 11 months ago in March 2015 due to treatment failure as suggested by CD4 count of 50 cells/mm(3). The present skin lesions started 2 months after the initiation of second-line ART. Differential diagnoses considered were Kaposi's sarcoma and immune reconstitution inflammatory syndrome (IRIS) related infections, but biopsy was suggestive of erythema elevatum diutinum (EED). Patient was started on oral dapsone 100 mg/day and increased to 200 mg/day to which he is responding gradually. In the present case, appearance of the lesions after initiation of second-line ART coupled with increase in CD4 count and decrease of viral load below undetectable level suggest that EED could be an IRIS.

    2015-09-28

    This is the first report describing a case where prolonged, severe malabsorption from brown bowel syndrome progressed to multifocally spread small bowel adenocarcinoma. This case involves a female patient who was initially diagnosed with chronic jejunitis associated with primary diffuse lymphangiectasia at the age of 26 years. The course of the disease was clinically, endoscopically, and histologically followed for 21 years until her death at the age 47 due to multifocal, metastasizing adenocarcinoma of the small bowel. Multiple lipofuscin deposits (so-called brown bowel syndrome) and severe jejunitis were observed microscopically, and sections of the small bowel showed dense lymphoplasmacytic infiltration of the lamina propria as well as blocked lymphatic vessels. After several decades, multifocal nests of adenocarcinoma cells and extensive, flat, neoplastic mucosal proliferations were found only in the small bowel, along with a loss of the mismatch repair protein MLH1 as a long-term consequence of chronic jejunitis with malabsorption. No evidence was found for hereditary nonpolyposis colon carcinoma syndrome. This article demonstrates for the first time multifocal carcinogenesis in the small bowel in a malabsorption syndrome in an enteritis-dysplasia-carcinoma sequence. PMID:26420973

After clinical examination and investigations, she was diagnosed with disseminated tuberculosis (including central nervous system involvement, and Human immunodeficiency virus/acquired immune deficiency syndrome. Her hospital stay was complicated. She developed stridor and a cerebrovascular accident with left hemiplegia. She died approximately 2 weeks after admission. The potential causes of her stridor included a mediastinal mass or a central mechanism secondary to tuberculosis meningitis. Limited resources precluded definitive imaging of the chest to rule out a mediastinal mass. Further, an autopsy was not done. Despite these limitations, this case is unique because it reports the presence of both stridor and tuberculosis meningitis in an adult patient.Keywords: Human immunodeficiency virus, acquired immune deficiency syndrome, meningitis, stridor, tuberculosis

    AIDS is an acquired immunodeficiency syndrome defined by a severe depletion of T cells and over 20 conventional degenerative and neoplastic diseases. In the U.S. and Europe, AIDS correlates to 95% with risk factors, such as about 8 years of promiscuous male homosexuality, intravenous drug use, or hemophilia. Since AIDS also correlates with antibody to a retrovirus, confirmed in about 40% of American cases, it has been hypothesized that this virus causes AIDS by killing T cells. Consequently, ...

  15. Immune reconstitution inflammatory syndrome in a patient with cryptococcal lymphadenitis as the first presentation of acquired immunodeficiency syndrome

    Tahir M

    2007-01-01

    Full Text Available Immune reconstitution inflammatory syndrome is commonly seen in acquired immunodeficiency syndrome (AIDS patients having concomitant opportunistic infection, following initiation of highly active anti-retroviral therapy (HAART. We describe IRIS in a young man with unknown human immunodeficiency virus (HIV status who presented with cryptococcal lymphadenitis as the first manifestation of AIDS. At presentation the patient had features overlapping with tuberculosis (TB lymphadenitis which was ruled out by fine needle aspiration cytology. The patient responded to antifungal treatment but following the start of HAART, symptoms recurred which were managed conservatively. Though TB is common in India, a thorough workup including histopathology of lymph node should be done before the patient is started on anti-tuberculosis treatment. HIV infected patients having opportunistic co-infection should be closely monitored following initiation of HAART.

    Acute febrile neutrophilic dermatosis (AFND), commonly known as Sweetâ€s syndrome, is a disorder seen in adult females, being extremely rare in children. Typical features include spiky fever, sudden eruption of raised painful erythematous to plum-colored nodules and plaques, neutrophilic leucocytosis, a dermal neutrophili infiltrate an a rapid response to systemic steroid. The eruption is believed to represent a hypersensitivity reaction to an antecedent infection or malignancy....

  17. Síndrome de Brown bilateral associada com hipermobilidade articular benigna: relato de caso Bilateral Brown's syndrome associated with benign joint hypermobility: a case report

    Full Text Available A síndrome de Brown é caracterizada por grande limitação de elevação em adução, elevação ligeiramente diminuída ou normal na abdução, anisotropia em "Y" ou "V", intorção do olho em supraversão e ducção forçada positiva. Sua causa se deve à inelastibilidade do músculo oblíquo superior ou por sua contenção em sua própria bainha. A hipermobilidade articular benigna é doença hereditária do tecido conectivo caracterizada por aumento da mobilidade em diversas articulações. Sua prevalência é muito variável em relação à idade, sexo e etnia, variando de 2 a 35% em homens e de 5 a 57% e mulheres. Neste relato os autores descrevem um caso de síndrome de Brown associada com hipermobilidade articular benigna e atentam para a associação pouco referida na literatura. J.C.S, masculino, 6 anos de idade, pardo, estudante, foi encaminhado à Universidade de Santo Amaro com queixa de exotropia há dois anos que aumentava na supraversão. Paciente com o diagnóstico de síndrome de Brown bilateral teve o diagnóstico de hipermobilidade articular benigna pelo Reumatologista. O paciente com hipermobilidade articular benigna pode desenvolver sintomas articulares como artralgia devido a uma inflamação articular. Acreditamos na possibilidade de que síndrome de Brown possa ter ocorrido devido a processo inflamatório na tróclea que teve início devido a hipermobilidade articular benigna.Brown's syndrome is characterized by a limitation of elevation in adduction, slight or normal limitation of elevation in abduction, divergence in straight upgaze (V-pattern, intorsion in upgaze and positive forced duction. It is caused by a tight or inelastic superior oblique tendon. Benign joint hypermobility is a hereditary disease of the connective tissue characterized by an increase of mobility in diverse joints. Its prevalence is very changeable regarding age range, sex and ethnicity, varying from 2 to 35% in men and 5 to 57% in women. In

  18. Brown-Séquard syndrome: a rare manifestation of decompression sickness.

    Tseng, W-S; Huang, N-C; Huang, W-S; Lee, H-C

    2015-12-01

    Neurological decompression sickness (DCS) is a rare condition that commonly leads to spinal cord injury. We report the case of a 30-year-old man who developed left-sided weakness and numbness after diving to a maximum depth of 15 m with a total dive time of 205min (10 repetitive dives). To the best of our knowledge, only six cases diagnosed as Brown-Séquard syndrome caused by DCS have been reported in the literature. Divers should be aware of the risk factors of DCS before diving and clinicians should make the diagnosis of spinal cord DCS based primarily on clinical symptoms, not on magnetic resonance imaging findings.

    2006-12-01

    Ganglion cysts of the spine are uncommon. They occur mostly in the dorsolateral trunk and arise with the greatest frequency in the lumbar spine. However, they are rarely symptomatic. We report a rare case of a patient with a ganglion cyst of the lower cervical spine presenting with acute Brown-Sequard syndrome. The patient had no history of trauma. Magnetic resonance imaging of the cervical spine showed a cystic lesion connecting to the synovial joint C6-7 and compressing the posterior aspect of the spinal cord. The patient underwent emergent C6-7 laminectomy with total removal of the cyst. Neurological function recovered completely 4 months after operation. Ganglion cysts should be considered in the differential diagnosis of an extradural mass of the cervical spine. Magnetic resonance imaging provides a rapid and correct diagnosis, and laminectomy with removal of the cyst results in good neurological recovery. PMID:17113987

  20. Optimising technetium 99m diethylenetriaminepenta-acetate lung clearance in patients with the acquired immunodeficiency syndrome

    Pneumocystis carinii pneumonia (PCP) has become a major cause of morbidity and mortality due to infectious diseases, largely as a result of the acquired immunodeficiency syndrome (AIDS) epidemic. Since the mortality from recurrent infection is between 40% and 60%, early diagnosis and therapy are the keys to survival. The role of technetium 99m diethylenetriaminepentacetate (DTPA) aerosol pulmonary clearance was studied in 81 patients with AIDS. The mathematical technique of curve stripping was found to be the optimal method of analysis and to provide an overall sensitivity of 94% for the detection of interstitial pneumonitis. The procedure was superior to standard pathology parameters and radiography and more convenient than gallium 67 scintigraphy. (orig.)

    Pirouzian, Amir; Holz, Huck A; Ip, Kenneth C; Sudesh, Rattehalli

    2010-04-01

    Horner syndrome, a triad of ptosis, anisocoria, and anhidrosis, results from interruption in the oculosympathetic pathway. It is classically described as either congenital or acquired to depict its underlying pathophysiology and requisite work-up. We report a case of a 10-month-old infant presenting with an acute onset of left Horner syndrome secondary to a spontaneous extracranial internal carotid artery dissection. To the best of our knowledge, this is the first case report in the literature of acute onset of acquired infantile Horner syndrome in association with spontaneous carotid artery dissection confirmed with magnetic resonance angiogram. PMID:20451860

  4. Nonspecific interstitial pneumonitis: a common cause of pulmonary disease in the acquired immunodeficiency syndrome

    During a 4.4-year period, nonspecific interstitial pneumonitis was seen in 41 of 110 (38%) patients with the acquired immunodeficiency syndrome and accounted for 32% (48/152) of all episodes of clinical pneumonitis. Diffuse alveolar damage was typically a feature of nonspecific interstitial pneumonitis, but neither lung biopsy nor bronchoalveolar lavage detected a pathogen. Of these 41 patients, 13 had no associated pulmonary tumor and had not been exposed to pulmonary toxins, whereas 28 patients had either concurrent pulmonary Kaposi sarcoma, previous experimental therapies, or a history of pneumocystis pneumonia or drug abuse. Of these 41, 23 had normal chest radiographs. The clinical features of patients with nonspecific interstitial pneumonitis were similar to those of patients with pneumocystis pneumonia, although histologic findings showed less severe alveolar damage in patients with nonspecific interstitial pneumonitis (p less than 0.001). Pathologic evaluation and clinical follow-up suggest that many clinical episodes of pneumonitis in patients with the acquired immunodeficiency syndrome are due to nonspecific interstitial pneumonitis of unknown cause

  5. Bone paracoccidioidomycosis associated with acquired immunodeficiency syndrome: evaluation by radiological methods - a case report

    Paracoccidioidomycosis is a chronic granulomatous disease, caused by the Paracoccidioides brasiliensis fungus. This disease involves primarily the lungs, although disseminated forms may occur. Bone involvement is rare, and is associated to systemic disease or may present as a focal lesion. An association between paracoccidioidomycosis and the acquired immunodeficiency syndrome (AIDS) was first established in 1989. There are only a few reports on this association, and none of them was the fungus isolated from bone lesions. This is the first case report on the paracoccidioidomycosis-AIDS association in which bone lesions demonstrated infection by P. brasiliensis. The authors propose the inclusion of paracoccidioidomycosis in the differential diagnosis of lytic bone lesions in patients with AIDS and discuss the role of radiological diagnostic in this case.

  6. 99mTc-ECD brain SPECT imaging in patients with acquired immunodeficiency syndromes

    In order to investigate the changes of regional cerebral blood flow (rCBF) in patients with acquired immunodeficiency syndromes (AIDS), 99mTc-ECD brain SPECT imaging was performed in 5 patients with AIDS and 16 sex and age matched normal controls, and the rCBF percentages compared to the cerebellum were calculated using a semi-quantitative processing software. Hypo-perfusions in the right and left frontal, temporal, parietal lobe, basal ganglia and left thalamus were seen in 1 patient with dementia. Hypo-perfusions in the right and left frontal and temporal lobe were seen in 4 asymptomatic patients. The rCBF in the right and left frontal, temporal, parietal lobe, basal ganglia and thalamus, front and pons were decreased significantly in patients with AIDS than those of the control subjects (p < 0.005). It is concluded that there exists reduced cortico-subcortical rCBF in AIDS patients

    This study investigated the social capital of Iranian patients living with acquired immune deficiency syndrome (AIDS) and the associated factors. In a cross-sectional study the Integrated Social Capital Questionnaire was filled by a sequential sample of 300 patients visiting a referral counselling centre in Tehran. The patients' social capital scores were around 50% in the trust, social cohesion, collective action and cooperation and political empowerment domains. The groups and networks membership domain scored the lowest (27.1%). In regression analysis, employment status was significantly associated with groups and networks membership; age, marital status and financial status were associated with collective action and cooperation; period of disease awareness and marital status affected social cohesion and inclusion; and having risky behaviour affected empowerment and political action. Efforts are needed to enhance the social capital of those patients living with AIDS who are younger, unemployed, divorced/widowed, with risky behaviours and shorter disease awareness. PMID:26750165

    2005-07-01

    We report a patient with acquired immunodeficiency syndrome dementia complex (ADC) that presented human immunodeficiency virus infection as an initial manifestation. A 34-year-old man developed disturbance of consciousness and severe abulia over 3 months. The CD4 lymphocyte count was 7.9/microl, while human immunodeficiency virus RNA in blood amounted to 4.2 x 10(4) copies/ml. T2-weighted magnetic resonance imaging showed diffusely high signal intensity in the deep white matter of both cerebral hemispheres. On the 20th hospital day, the patient died of sepsis caused by methicillin-resistant Staphylococcus aureus. Autopsy findings in the brain included increased glial cells and multinucleated giant cells in cerebral white matter and subcortical gray matter. These features were compatible with ADC.

  9. Toxoplasmosis of spinal cord in acquired immunodeficiency syndrome patient presenting as paraparesis: A rare entity

    Sachin R Agrawal

    2014-01-01

    Full Text Available Although brain has been the most common site for toxoplasma infection in acquired immunodeficiency syndrome patients, involvement of spinal cord by toxoplasma has been rarely found. Spinal cord toxoplasmosis can present as acute onset weakness in both lower limbs associated with sensory and bladder dysfunction. A presumptive diagnosis can be made in patients with CD4 count <100/mm 3 based on a positive serum Toxoplasma gondii IgG antibodies, no recent prophylaxis against toxoplasmosis, intramedullary ring enhancing lesion in spinal cord supported by similar lesions in brain parenchyma. Institutions of antitoxoplasma treatment in such patients result in prompt clinical response and therefore avoiding the need of unnecessary invasive diagnostic tests. Here, we report a case of toxoplasmic myelitis in immunocompromised patient presenting as myelopathy who showed significant clinical improvement after starting antitoxoplasma treatment. Hence toxoplasmic myelitis should be considered in toxoplasma seropositive immunocompromised patients presenting as myelopathy and imaging studies showing ring enhancing intramedullary lesion.

    Pancreatic tuberculosis (TB) is a relatively rare disease that can mimic carcinoma,lymphoma,cystic neoplasia,retroperitoneal tumors,pancreatitis or pseudocysts.Here,I report the case of a 31-year-old immigrant Burmese woman who exhibited epigastralgia,fever,weight loss and an epigastric mass.The patient was diagnosed with pancreatic TB and acquired immunodeficiency syndrome,and was treated with antituberculous drugs and percutaneous catheter drainage without a laparotomy.The clinical presentation,radiographic investigation and management of pancreatic TB are summarized in this paper to emphasize the importance of considering this rare disease in the differential diagnosis of pancreatic masses concomitant with human immunodeficiency virus infection.I also emphasize the need for both histopathological and microbiological diagnosis via fineneedle aspiration.

  11. Gallium-67 scans of the chest in patients with acquired immunodeficiency syndrome

    Eighty-six [67Ga]citrate chest scans were performed in 71 adult patients with the acquired immunodeficiency syndrome. Forty-five of these patients also had Kaposi's sarcoma. Only 29 of 57 abnormal scans were correlated with abnormal chest radiographs. Chest radiographs were negative for 27 scans and unavailable for one. Several scan patterns were seen. Diffusely increased lung uptake was seen most commonly with Pneumocystis carinii pneumonia, but also other infections and noninfectious inflammatory conditions. Focal uptake corresponding to regional lymph node groups occurred most often with Mycobacterium avium-intracellulare but aslo with lymphoma. Localized intrapulmonary uptake was seen in bacterial pneumonias. Perihilar activity occurred in two cases. When chest radiographs were abnormal and 67Ga scans negative, the most common diagnosis was pulmonary Kaposi's sarcoma

  12. Chest radiographs in acquired antibody deficiency syndrome with chronic granulomatous inflammation

    Ten cases of acquired antibody deficiency syndrome with chronic granulomatous infection were diagnosed in our hospital during the past 10 years. We were able to perform a retrospective analysis of the initial and follow-up chest radiographs in 8 of these patients. The following pathological findings could be demonstrated: 1. increased bronchovascular markings in the basal lung fields, 2. reticular densities in the middle and basal lung fields, 3. confluent nodular densities of varying size in the periphery of the basal and middle fields, 4. pulmonary infiltrates in the middle and lower lobes, 5. hilar node enlargement of moderate extent. Findings 2, 3 and 5 completely disappeared under steroid therapy whereas 1 showed only partial recovery. If both the radiologic and serologic findings are considered, it is possible to differentiate this disease from sarcoidosis. (orig.)

  13. Human papillomavirus-associated cancers as acquired immunodeficiency syndrome defining illnesses

    Shohreh Shahabi

    2013-04-01

    Full Text Available The Centers for Disease Control currently report cervical, vulvar, vaginal, anal and some head and neck cancers as human papillomavirus (HPV-associated cancers. Only cervical cancer is listed amongst acquired immunodeficiency syndrome (AIDS defining illnesses. All of these cancers may represent progression of the immunocompromised state with the inability to eradicate viral infection. This study reports the case of a 27-year old HIV positive female presenting with a persistent right vulvar exophytic lesion. High-risk HPV analysis and immunostaining for P16 were both positive. A biopsy of the lesion revealed invasive squamous cell carcinoma. The patient underwent neoadjuvant radiation and chemotherapy followed by a radical vulvectomy. During treatment, her CD4 T-lymphocyte count decreased to 120 advancing her condition from HIV to AIDS. This case suggests that all HPV-associated cancers should be included as AIDS defining illnesses.

  17. Thermal and sedimentation stress are unlikely causes of brown spot syndrome in the coral reef sponge, Ianthella basta.

    Heidi M Luter

    Full Text Available BACKGROUND: Marine diseases are being increasingly linked to anthropogenic factors including global and local stressors. On the Great Barrier Reef, up to 66% of the Ianthella basta population was recently found to be afflicted by a syndrome characterized by brown spot lesions and necrotic tissue. METHODOLOGY/PRINCIPAL FINDINGS: Manipulative experiments were undertaken to ascertain the role of environmental stressors in this syndrome. Specifically, the effects of elevated temperature and sedimentation on sponge health and symbiont stability in I. basta were examined. Neither elevated temperature nor increased sedimentation were responsible for the brown spot lesions, but sponges exposed to 32°C developed substantial discoloration and deterioration of their tissues, resulting in death after eight days and a higher microbial diversity in those samples. No shifts in the microbial community of I. basta were observed across a latitudinal gradient or with increased sedimentation, with three previously described symbionts dominating the community of all sponges (Alphaproteobacteria, Gammaproteobacteria and Thaumarchaea. CONCLUSIONS/SIGNIFICANCE: Results from this study highlight the stable microbial community of I. basta and indicate that thermal and sedimentation stress are not responsible for the brown spot lesions currently affecting this abundant and ecologically important sponge species.

  18. Respiratory failure in patients with acquired immunodeficiency syndrome and Pneumocystis carinii pneumonia.

    1986-05-01

    Seven patients with acquired immunodeficiency syndrome (AIDS) and Pneumocystis carinii pneumonia were studied to define the pathophysiology of their respiratory failure. The patients had fever, cough, dyspnea, hypoxemia, and diffuse infiltrates on chest x-ray. Biopsies revealed a spectrum of alveolar filling, interstitial edema and infiltration, and fibrosis. The patients were studied on mechanical ventilation to assess the effect of positive end-expiratory pressure (PEEP) and supplemental oxygen on shunt fraction. Mean anatomic shunt (measured on 100% oxygen) was 34 +/- 8%, which increased significantly (p less than .001) to 43 +/- 9% when the FIO2 was decreased to 40% to 60% (physiologic shunt), indicating ventilation/perfusion (V/Q) imbalance or impaired diffusion. Increasing PEEP by 9 +/- 2 cm H2O reduced the anatomic shunt to 30 +/- 7% (p less than .01) and the physiologic shunt to 37 +/- 7% (p less than .02). There was a similar decrease in anatomic and physiologic shunts in five studies, a greater decrease in physiologic shunt in four, and a greater decrease in anatomic shunt in two. Evidence of alveolar recruitment with PEEP, measured by an increase in static thoracic compliance, was found in only one study. There was no correlation between the effect of PEEP on compliance and its effect on shunt. The data suggest that in patients with AIDS and P. carinii pneumonia, PEEP can decrease shunt by reducing the anatomic shunt, improving V/Q imbalance, and converting areas of anatomic shunt to areas of low V/Q. P. carinii pneumonia in patients with AIDS can produce a clinical and pathophysiologic pattern similar to that described in the adult respiratory distress syndrome. PMID:3516574

    2015-07-01

    Acquired von Willebrand syndrome (AVWS) is a rare bleeding disorder similar to inherited von Willebrand disease. We describe a 78-year-old woman with coexistent idiopathic thrombocytopenic purpura (ITP) and AVWS. The patient had once been admitted to our hospital because of cerebral infarction. Her platelet count had been normal at that time. Ten years later, she showed a severe bleeding tendency (platelet count 3.2×10(4)/μl). Analysis of hemostatic parameters showed very low (IgG4) to VWF was detected by enzyme linked immunosorbent assay (ELISA). Factor XIII activity was 42%. Treatment with corticosteroids did not improve the thrombocytopenia, but did correct the bleeding diathesis. Also, VWF: Rco and VIII: C showed normalization. These findings indicated that the patient had ITP associated with AVWS. All reported cases of AVWS associated with systemic lupus erythematosus were cured by appropriate treatment of the underlying autoimmune disease with prednisone or immunosuppression. This bleeding disorder occurs mainly in patients with lymphoproliferative, myeloproliferative, cardiovascular and immunologic disorders, but no patients with ITP have previously been reported. This patient had the rare presentation of AVWS complicated by ITP and factor XIII deficiency. PMID:26256928

  1. Kaposi sarcoma of the conjunctiva and eyelids associated with the acquired immunodeficiency syndrome

    Three studies were performed to assess more accurately the prevalence, natural history, and appropriate treatment of acquired immunodeficiency syndrome (AIDS)-related Kaposi sarcoma involving ocular structures. The first study was a prospective examination of 100 male homosexuals with AIDS-related Kaposi sarcoma for signs of ophthalmic involvement. Of the 20 patients who had ophthalmic lesions, 16 had eyelid lesions and seven had conjunctival lesions. In four patients, the ophthalmic lesion was the first, and initially the only, clinically identified manifestation of Kaposi sarcoma. The second study was a retrospective review of all patients with ophthalmic Kaposi sarcoma examined at one institution over a six-year period to determine its natural history and response to therapy. Most lesions were slowly progressive and responded to systemic drug therapy. Six patients were successfully treated with radiation therapy to prevent complications. The third study was a retrospective review of all patients with AIDS-related ophthalmic Kaposi sarcoma treated with local irradiation by one radiation oncologist. Each of 12 patients showed a response to treatment, and ten had a complete resolution of lesions, but recurrences were common. Side effects included skin erythema in six patients and hair loss in one patient. For local treatment of ophthalmic Kaposi sarcoma, irradiation appears to be safe and effective for palliative therapy

  2. Computed tomography of the lungs in acquired immunodeficiency syndrome. An early indicator of interstitial pneumonia

    Hartelius, H.; Gaub, J.; Jensen, L.I.; Jensen, J.; Faber, V.

    Computed tomography of the chest was performed on 42 occasions as part of the diagnostic work-up in 26 homosexual men with, or suspected of the acquired immunodeficiency syndrome (AIDS). In 17 cases both the chest radiographs and the lung scans were abnormal, and bronchoscopy and/or lung biopsy established an etiologic diagnosis in the majority of these cases. In 9 cases CT of the lungs revealed unequivocal interstitial infiltration in the presence of a normal chest radiography, and subsequently and etiologic agent was demonstrated in all these cases. In 9 cases, patients with symptoms indicative of pulmonary infection had both a normal chest radiograph and a normal lung scan, and in none of these cases did the clinical course or additional diagnostic procedures indicate the presence of current opportunistic lung infection. CT of the lungs seems to identify accurately those patients with severe HIV-related diseases in whom invasive diagnostic procedures such as bronchoalveolar lavage and/or lung biopsy should be done.

  3. Unsuspected pulmonary alveolar proteinosis in a patient with acquired immunodeficiency syndrome: a case report

    Niazi Masooma

    2011-02-01

    Full Text Available Abstract Introduction Diffuse lung infiltrates are a common finding in patients with acquired immunodeficiency syndrome and causes range from infectious processes to malignancies or interstitial lung diseases. Pulmonary alveolar proteinosis is a rare pulmonary disorder rarely reported in patients infected with human immunodeficiency virus. Secondary pulmonary alveolar proteinosis is associated with conditions involving functional impairment or reduced numbers of alveolar macrophages. It can be caused by hematologic malignancies, inhalation of toxic dust, fumes or gases, infectious or pharmacologic immunosuppression, or lysinuric protein intolerance. Case presentation A 42-year-old African American man infected with human immunodeficiency virus was admitted with chronic respiratory symptoms and diffuse pulmonary infiltrates. Chest computed tomography revealed bilateral spontaneous pneumothoraces, for which he required bilateral chest tubes. Initial laboratory investigations did not reveal any contributory conditions. Histological examination of a lung biopsy taken during video-assisted thoracoscopy showed pulmonary alveolar proteinosis concurrent with cytomegalovirus pneumonitis. After ganciclovir treatment, our patient showed radiologic and clinical improvement. Conclusion The differential diagnosis for patients with immunosuppression and lung infiltrates requires extensive investigations. As pulmonary alveolar proteinosis is rare, the diagnosis can be easily missed. Our case highlights the importance of invasive investigations and histology in the management of patients infected with human immunodeficiency virus and pulmonary disease who do not respond to empiric therapy.

  4. Anterior segment manifestations of human immunodeficiency virus/acquired immune deficiency syndrome

    Biswas Jyotirmay

    Full Text Available Ocular complications are known to occur as a result of human immunodeficiency virus (HIV disease. They can be severe leading to ocular morbidity and visual handicap. Cytomegalovirus (CMV retinitis is the commonest ocular opportunistic infection seen in acquired immune deficiency syndrome (AIDS. Though posterior segment lesions can be more vision-threatening, there are varied anterior segment manifestations which can also lead to ocular morbidity and more so can affect the quality of life of a HIV-positive person. Effective antiretroviral therapy and improved prophylaxis and treatment of opportunistic infections have led to an increase in the survival of an individual afflicted with AIDS. This in turn has led to an increase in the prevalence of anterior segment and adnexal disorders. Common lesions include relatively benign conditions such as blepharitis and dry eye, to infections such as herpes zoster ophthalmicus and molluscum contagiosum and malignancies such as squamous cell carcinoma and Kaposi′s sarcoma. With the advent of highly active antiretroviral therapy, a new phenomenon known as immune recovery uveitis which presents with increased inflammation, has been noted to be on the rise. Several drugs used in the management of AIDS such as nevirapine or indinavir can themselves lead to severe inflammation in the anterior segment and adnexa of the eye. This article is a comprehensive update of the important anterior segment and adnexal manifestations in HIV-positive patients with special reference to their prevalence in the Indian population.

  5. Infection and T lymphocyte subpopulations: changes associated with bacteremia and the acquired immunodeficiency syndrome.

    Fishman, J A; Martell, K M; Rubin, R H

    1983-01-01

    Patients with bacteremia, bacterial endocarditis, or acquired immunodeficiency syndrome (AIDS) were prospectively studied using monoclonal antibody reagents to assess alterations in T-lymphocyte subpopulations. Patients with endocarditis had significantly higher ratios of T-helper (OKT4+) to T-suppressor-cytotoxic (OKT8+) cells than did patients with bacteremia alone. Staphylococcus aureus endocarditis patients had a mean ratio of 8.49 (range 4.73-22.36) while S aureus bacteremia had a mean ratio of 2.75 (range 2.15 to 3.21). Similar results were found with Staphylococcus epidermidis endocarditis (mean 1.62) and bacteremia (mean 1.23). Klebsiella pneumoniae endocarditis (5.10) and sepsis (4.32), and E coli bacteremia (2.15). Nine male patients with AIDS had markedly depressed ratios (mean 0.25, range 0.04 to 0.67) while eight male homosexuals with unexplained lymphadenopathy ("pre-AIDS") had normal or increased ratios. Bacteremic infections are associated with an increased OKT4+/OKT8+ ratio with the degree of increase dependent upon virulence, location, and duration of infection. The immunomodulating effects of infection are manifested in changes in T-cell subsets, and these measurements can be useful in clinical management. PMID:6094086

  6. Erythrovirus B19 infection in acquired immunodeficiency syndrome: screening by histopathology, immunohistochemistry, and in situ hybridization

    2006-06-01

    Full Text Available Erythrovirus B19 infects erythrocytic progenitors, transiently interrupting erythropoiesis. In AIDS patients it causes chronic anemia amenable to treatment. We looked for evidences of B19 infection in stored bone marrow material from patients with acquired immunodeficiency syndrome. Histological sections were made from stored paraffin blocks from 33 autopsies (39 blocks and 35 biopsies (45 blocks, 30 patients performed from 1988 to 2002. They were examined after hematoxylin-eosin (HE staining, immunohistochemical (IHC, and in situ hybridization. HE revealed intra-nuclear inclusion bodies ("lantern cells" suggesting B19 infection in 19 sections corresponding to 19 of 63 patients examined with this test. Seven of 78 sections subjected to immunohistochemistry were positive, corresponding to 7 of 58 patients examined with this test. Fourteen sections corresponding to 13 of the 20 HE and/or IHC positive patients were subjected to in situ hybridization, with six positives results. Among the 13 patients subjected to the three techniques, only one gave unequivocal positive results in all and was considered a true positive. The frequency of B19 infection (1/63 patients in the material examined can be deemed low.

    2012-02-01

    Full Text Available Abstract Introduction Hypereosinophilic syndrome is defined as a prolonged state (more than six months of eosinophilia (greater than 1500 cells/μL, without an apparent etiology and with end-organ damage. Hypereosinophilic syndrome can cause coagulation abnormalities. Among hypereosinophilic syndrome types, the lymphocytic variant (lymphocytic hypereosinophilic syndrome is derived from a monoclonal proliferation of T lymphocytes. Here, we describe the case of a patient with lymphocytic hypereosinophilic syndrome who presented with a coagulation abnormality. To the best of our knowledge, this is the first such report including a detailed clinical picture and temporal cytokine profile. Case presentation A 77-year-old Japanese man presented to our facility with massive hematuria and hypereosinophilia (greater than 2600 cells/μl. His eosinophilia first appeared five years earlier when he developed femoral artery occlusion. He manifested with multiple hematomas and prolonged activated partial thromboplastin time. His IgG4 level was remarkably elevated (greater than 2000 mg/dL. Polymerase chain reaction tests of peripheral blood and bone marrow identified lymphocytic hypereosinophilic syndrome. His prolonged activated partial thromboplastin time was found to be due to acquired hemophilia. Glucocorticoids suppressed both the hypereosinophilia and coagulation abnormality. However, tapering of glucocorticoids led to a relapse of the coagulation abnormality alone, without eosinophilia. Tumor necrosis factor α, interleukin-5, and/or eotaxin-3 may have caused the hypereosinophilia, and interleukin-10 was correlated with the coagulation abnormality. Conclusions To the best of our knowledge, this is the first case in which lymphocytic hypereosinophilic syndrome and IgG4-related disease have overlapped. In addition, our patient is only the second case of hypereosinophilic disease that manifested with acquired hemophilia. Our patient relapsed with the

    Brown-Vialetto-Van Laere syndrome (BVVLS [MIM 211530]) is a rare neurological disorder characterized by infancy onset sensorineural deafness and ponto-bulbar palsy. Mutations in SLC52A3 (formerly C20orf54), coding for riboflavin transporter 2 (hRFT2), have been identified as the molecular genetic correlate in several individuals with BVVLS. Exome sequencing of just one single case revealed that compound heterozygosity for two pathogenic mutations in the SLC52A2 gene coding for riboflavin tran...

  9. Acquired immunodeficiency syndrome-related primary cerebral lymphoma: response to irradiation

    Acquired immunodeficiency syndrome-related primary cerebral lymphoma (AIDS-PCL) is uncommon. Fourteen cases of presumed AIDS-PCL between 1986 and 1995 were reviewed retrospectively in order to characterize the natural history, and the response to radiotherapy. The median age was 38 years (range 24-65). The median interval between seropositive diagnosis of HIV and AIDS-PCL was 28 months (range 5-113). The median duration of symptoms was 2 weeks (range 0.2-12). At presentation, the Eastern Cooperative Oncology Group performance status (PS) was PS1 (2/14 patients), PS2 (6/14) and PS3 (6/14). The symptoms and signs were non-specific and depended on the site and extent of cerebral involvement. There was no characteristic pattern of brain imaging in terms of size, number, location or pattern of contrast enhancement of the cerebral lesions. Nine patients received various fractionation-dose schedules (range 8-50 Gy). Complete and partial responses were seen in 2/9 and 3/9 cases, respectively. Clinical stabilization of neurological symptoms was noted in 3/9 cases and disease progression in 1/9. The median survival times (MST) from presentation for irradiated and non-irradiated patients were 9.3 and 2.1 weeks, respectively (range 0.9-43.1). Although patient selection introduced bias, there appears to be a modest improvement in MST for treated patients. The MST with radiotherapy alone remains poor, but radiotherapy may provide palliation. For some selected patients, a prolonged response is possible. Copyright (1999) Blackwell Science Pty Ltd

    2016-05-01

    Acquired von Willebrand syndrome (AVWS) is a rare bleeding disorder that may cause life-threatening hemorrhages in patients with plasma cell dyscrasias (PCDs). Early diagnosis and treatment require a thorough understanding of its underlying pathophysiology. Two patients with IgG MGUS presented with dramatically decreased plasma von Willebrand factor (VWF) and a severe type-1 pattern on multimer analysis. A prompt response to intravenous immunoglobulins (IVIG), but not to VWF/FVIII, was consistent with accelerated immunologic clearance of plasma VWF. Another IgG MGUS patient showed a type-2 pattern and a less pronounced response to IVIG, suggesting that additional mechanism(s) contributed to AVWS evolution. In a patient with Waldenström's macroglobulinemia and severe depletion of plasma VWF, multimer analysis indicated association of the IgM paraprotein with VWF before, but not after plasmapheresis, resulting in destruction of the agarose gel and a characteristically distorted band structure of VWF multimers. A type-2 pattern with highly abnormal VWF triplets and laboratory evidence of excessive fibrinolytic activity suggested that plasmin-mediated VWF degradation contributed to AVWS in a patient with multiple myeloma (MM) and AL amyloidosis. Finally, in a patient with IgG MM, maximally prolonged PFA-100® closure times and a specific defect in ristocetin-induced platelet agglutination, both of which resolved after remission induction, indicated interference of the paraprotein with VWF binding to platelet GPIb. Importantly, in none of the six patients, circulating autoantibodies to VWF were detected by a specific in-house ELISA. In summary, when evaluating PCD patients with severe bleeding symptoms, AVWS due to various pathogenic mechanisms should be considered. PMID:27040683

  11. Correlation of diagnostic imaging and autopsy findings of eight patients with acquired immune deficiency syndrome

    Objective: To investigate the imaging findings with pathologic correlation in patients with acquired immune deficiency syndrome (AIDS). Methods: Imaging findings, autopsy and pathological data were retrospectively analyzed in eight patients with AIDS. Routine CT scanning of different body parts was performed during their hospitalization. CT scanning was performed from the skull to the pelvis immediately following their death. After routine formalin fixing, 7 cadavers were cross sectioned for autopsy in freezing state and 1 for gross autopsy. Tissues were obtained from each sections and organs for pathological examinations. Results: The autopsy data showed parasitic infections (5 cases), bacterial infections (3 cases), fungal infections (2 cases), virus infections (2 cases), lymphoma (1 case) and cerebrovascular diseases (1 case)in eight patients with AIDS. The CT scanning demonstrated symmetrical ground glass liked shadows with pulmonary hilus as the center in 5 cases of pulmonary PCP infection; pulmonary patchy shadows, scattering distribution of nodular shadows, extensive military nodular shadows with even distribution and tuberculous pleurisy; cloudy shadows for 2 cases of fungi infection with multiple foci of chronic inflammation; pulmonary net-like parenchymal changes for 2 cases of pulmonary CMV infection; thickened intestinal wall and narrowed intestinal lumen for 1 case of intestinal tumor; low density shadows of brain tissue for 1 case of CMV encephalitis and MRI findings of high T1 and high T2 signals as well as MRA findings of broken vascular channels in liquefied areas of brain tissues; patchy low density areas inside a cyst of brain for one case of brain toxoplasmosis infection; multiple small patchy low density areas in cerebral basal ganglia for one case of brain cryptococcus infection. Conclusions: In AIDS patients, infection and tumor may occur in various organs resulting in complex symptoms, which makes it more complicated and difficult to make

    Acquired von Willebrand Syndrome (AVWS) is a rare bleeding disorder associated with hematoproliferative disorders, autoimmune conditions, neoplasia, and cardiovascular disorders that often presents a diagnostic challenge. Monoclonal gammopathy of undetermined significance (MGUS) is one of the most common causes of AVWS that typically presents later in life with mucocutaneous or postsurgical bleeding and multimers consistent with type I or II von Willebrand Disease (VWD). Here we present the c...

  15. Cholecystitis in a child with acquired immunodeficiency syndrome: ultrasonographic findings in a case of uncommon presentation during childhood

    We present the case of a boy with acquired immunodeficiency syndrome (AIDS) in whom ultrasound revealed the presence of a calculous cholecystitis. Abdominal ultrasound was essential in the initial diagnosis and the assessment of the response to treatment. This entity has rarely been reported in the pediatric radiology literature. In our patient, the cholecystitis may have been caused by infection, and the involvement of regional lymphatic obstruction in the pathogenesis is considered. (Author) 14 refs

  16. Acquired immunodeficiency syndrome-associated cancers in Sub-Saharan Africa.

    Thomas, J O

    2001-04-01

    Sub-Saharan Africa is considered home to more than 60% of all human immunodeficiency virus (HIV) infected cases, with an estimated adult prevalence of 8.0%. It is stated that this region has contributed more than 90% of childhood deaths related to HIV infection and about 93% of childhood acquired immunodeficiency syndrome (AIDS)-related deaths. Although no country in Africa is spared of the infection, the bulk is seen in East and South Africa, with the highest recorded rates of 20% to 50% in Zimbabwe. On the other hand, West Africa is less affected, while countries in Central Africa have relatively stable infection rates. Although infections, especially tuberculosis, have emerged as the most important HIV/AIDS-associated killers in recent times, AIDS-associated malignancies are increasingly identified in the late stages. As a result of incomplete data from African countries, it is unclear whether the epidemiology and risks of these cancers are the same as observed in the developed countries. Since the advent of AIDS, epidemic Kaposi's sarcoma (KS) has become more common in both sexes in Africa, with a dramatic lowering of the male to female ratio from 19:1 to 1.7:1, especially in East Africa. Although there has been a rising trend of AIDS-associated non-Hodgkin's lymphoma (NHL) worldwide, there is an apparently lower risk in Africa compared with that in the developing world. At present, there is no strong evidence linking increased incidence of invasive cervical cancer to the HIV epidemic; however, some studies have demonstrated an association between HIV and the increased prevalence of human papilloma virus (HPV) and cervical intraepithelial neoplasia (CIN). On the other hand, HIV infection is now established as a risk factor for the development of squamous cell neoplasia of the conjunctiva based on studies from Rwanda, Malawi, and Uganda. Despite the problems and limitations of information from sub-Saharan Africa, interesting trends of HIV/AIDS-related cancers

  20. Production of acquired immunodeficiency syndrome-associated retrovirus in human and nonhuman cells transfected with an infectious molecular clone

    The authors considered an infectious molecular clone of acquired immunodeficiency syndrome-associated retrovirus. Upon transfection, this clone directed the production of infectious virus particles in a wide variety of cells in addition to human T4 cells. The progeny, infectious virions, were synthesized in mouse, mink, monkey, and several human non-T cell lines, indicating the absence of any intracellular obstacle to viral RNA or protein production or assembly. During the course of these studies, a human colon carcinoma cell line, exquisitely sensitive to DNA transfection, was identified

    The prevalence of lymphoma in primary immunodeficiency cases and autoimmune diseases, as well as on a background of immunodeficiency following organ transplants, is increasing. The lymphoma treatment success rate is known to be a low prognosis. Our study aimed to emphasize the low survival rates in immunodeficient vs. immunocompetent lymphoma patients and also to investigate the effect of rituximab in patients with ataxia telangiectasia and other immunodeficiencies. We summarized the clinical characteristics and treatment results of 17 cases with primary immunodeficiency that developed non-Hodgkin lymphoma (NHL) and Hodgkin lymphoma (HL) retrospectively. Seven patients were diagnosed with ataxia-telangiectasia, two with common variable immunodeficiency, two with selective IgA deficiency, one with X-related lymphoproliferative syndrome, one with Wiskott-Aldrich syndrome, one with Epstein-Barr virus-related lymphoproliferative syndrome, one with interleukin-2-inducible T-cell kinase (ITK) deficiency, and one with lymphoma developing after autoimmune lymphoproliferative syndrome (ALPS). One patient underwent a renal transplant. Of the nine males and eight females (aged 3-12 years, median = 7) that developed lymphoma, seven were diagnosed with HL and ten with NHL (seven B-cell, three T-cell). The NHL patients were started on the Berlin-Frankfurt-Münster, POG9317, LMB-96, or R-CHOP treatment protocols with reduced chemotherapy dosages. HL cases were started on the doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) and/or cyclophosphamide, vincristine, procarbazine, and prednisone (COPP) protocol, also with modified dosages. Importantly, all seven cases of HL are alive and in remission, while six of the ten NHL patients have died. Primary immunodeficiency is a strong predisposing factor for developing lymphoma. Low treatment success rates relative to other lymphomas and difficulties encountered during treatment indicate that new treatment agents are needed

    2015-01-01

    Full Text Available Introduction: Ondine’s Curse is a catastrophic but rare condition in adults. It is referred to as a congenital or acquired condition, in which the patient cannot breathe automatically while asleep. Acquired causes of this disease can be any cause affecting the ventrolateral part of the medulla, which is considered to be the breathing center in humans.    Case Report:   A 51-year-old woman, with ataxia and the symptoms and signs of rising Intra-Cranial Pressure, who underwent ventriculoperitoneal shunting and removal of tumour, developed episodic apnea during sleep after surgery and hypercapnia when awake. In her post-operative CT scan, some fine spots of hypodensity in the left lateral part of the medulla were observed. She was managed pharmacologically and underwent tracheotomy. After 50 days, she was discharged from the hospital when she was able to breathe normally.   Conclusion:  Having experience with this condition after resection of a fourth ventricle tumor, it was found that Ondine’s Curse can be considered as one of the complications of  posterior fossa surgery and is curable by proper management.

  5. A preliminary report of 99Tcm-ECD brain SPECT imaging in patients with acquired immunodeficiency syndrome

    Objective: To investigate the changes of regional cerebral blood flow (rCBF) in patients with acquired immunodeficiency syndrome (AIDS). Methods: 99Tcm-ECD brain SPECT imaging was performed on 5 patients with AIDS and 16 sex- and age-matched normal controls. The rCBF percentages compared to the cerebellum were calculated using a semi-quantitative processing software. Results: Hypo-perfusions in the right and left frontal, temporal, parietal lobe, basal ganglia and left thalamus were seen in 1 patient with dementia. Hypo-perfusions in the right and left frontal and temporal lobe were seen in 4 patients without dementia. The rCBF in the right and left frontal, temporal, parietal lobe, basal ganglia and thalamus, straight gyri and pons decreased significantly in patients with AIDS than those of the control subjects (P < 0.01). Conclusion: There is reduced cortico-subcortical rCBF in patients with AIDS

    2016-01-01

    Anaplastic large cell lymphoma (ALCL) is an uncommon disease, accounting for <5% of all cases of non-Hodgkin's lymphoma. We report a case of 48-year-old male who presented a clinically benign swelling in the right anterior palatal region since last 2 months. Radiographic evaluation showed no bone loss in palatal area. Histological and radiological examination was in favor of a peripheral reactive lesion like pyogenic granuloma or a benign salivary gland tumor. Immunohistochemistry confirmed the diagnosis of anaplastic lymphoma kinase-negative (ALK(-)) ALCL. Further laboratory tests ELISA for human immunodeficiency virus (HIV) and CD4 cell count was done which showed positivity for HIV. To the best of our knowledge, it is the first case of ALK(-) ALCL in the hard palate presenting as the first clinical manifestation of acquired immune deficiency syndrome. PMID:27041916

  8. Primary stomal lymphoma. An unusual complication of ileostomy in a patient with transfusion-related acquired immune deficiency syndrome.

    Levecq, H; Hautefeuille, M; Hoang, C; Galian, A; Hautefeuille, P; Rambaud, J C

    1990-02-15

    A 73-year-old heterosexual man developed a high-grade non-Hodgkin's lymphoma at the site of an ileostomy only 2 years after proctectomy for undetermined colitis not cured by previous colectomy. In fact, the early occurrence of this usually very late and rare complication of ileostomy was probably favored by the simultaneous presence of acquired immune deficiency syndrome (AIDS) due to repeated blood transfusions for refractory anemia with excess blasts. The intestinal location of the tumor, its high-grade malignancy and B-cell origin are all features of AIDS-related non-Hodgkin's lymphoma. This case report seems to be one of the rarely identified examples of the cooperation between general predisposing factors and local irritating agents at the origin of a malignant tumor.

    AIMS: Impaired repolarization in cardiac myocytes can lead to long QT syndrome (LQTS), with delayed repolarization and increased susceptibility to Torsades de Pointes (TdP) arrhythmias. Current pharmacological treatment of LQTS is often inadequate. This study sought to evaluate the antiarrhythmic...... effect of a novel compound (NS1643) that activates the rapid delayed-rectifier K+ current, I(Kr), in two rabbit models of acquired LQTS. METHODS AND RESULTS: We used two clinically relevant in vivo rabbit models of TdP in which we infused NS1643 or vehicle: (i) three-week atrioventricular block with...... ventricular bradypacing; (ii) dofetilide-induced I(Kr) inhibition in methoxamine-sensitized rabbits. In addition, we studied effects on ionic currents in cardiomyocytes with I(Kr) suppressed by bradycardia remodelling or dofetilide exposure. Bradypaced rabbits developed QT interval prolongation, spontaneous...

  10. Wernicke's Encephalopathy: An Unusual Consequence of the Acquired Immune Deficiency Syndrome-Case Report and Literature Review.

    Larsen, Timothy R; Dragu, Dritan; Williams, Michael

    2013-01-01

    Introduction. Wernicke's encephalopathy is a well-described syndrome characterized by the classic triad of confusion, ataxia, and ophthalmoplegia. Wernicke's encephalopathy results from thiamine (vitamin B1) deficiency. Common causes include alcoholism and gastric disorders. Wernicke's has been described in patients with acquired immune deficiency syndrome (AIDS); however, given these patients' immunosuppressed state, the diagnosis of Wernicke's encephalopathy is not apparent. Case Presentation. A 31-year-old previously healthy male presented to the ER complaining of progressive dyspnea. Workup revealed HIV/AIDS and PCP pneumonia. He was treated and improved. On day 14 he became confused and developed nystagmus and ataxia. Considering his immunocompromised state, infectious and neoplastic etiologies topped the differential diagnosis. CT head was negative. Lumbar puncture was unremarkable. Brain MRI revealed increased T2 signal in the medial thalamus bilaterally. Intravenous thiamine was administered resulting in resolution of symptoms. Discussion. The classic triad of Wernicke's encephalopathy occurs in 10% of cases. When immunosuppressed patients develop acute neurologic symptoms infectious or neoplastic etiologies must be excluded. However, given the relative safety of thiamine supplementation, there should be a low threshold for initiating therapy in order to reverse the symptoms and prevent progression to Korsakoff dementia, which is permanent.

    Geomyces destructans produces the white fungal growth on the muzzle and the tacky white discoloration on wings and ears that characterize white-nose syndrome (WNS) in cave-hibernating bats. To test the hypothesis that postemergent WNS-infected bats recover from infection with G. destructans, 30 little brown bats (Myotis lucifugus) were collected in May 2009 from a WNS-affected hibernation site in New Jersey. All bats were confirmed to be infected with G. destructans using a noninvasive fungal tape method to identify the conidia of G. destructans and polymerase chain reaction (PCR). The bats were then held in captivity and given supportive care for 70 days. Of the 26 bats that survived and were humanely killed after 70 days, 25 showed significant improvement in the external appearance of wing membranes, had no microscopic evidence of infection by G. destructans, and had wing tissue samples that were negative for G. destructans by PCR. A subset of the bats was treated topically at the beginning of the rehabilitation study with a dilute vinegar solution, but treatment with vinegar provided no added advantage to recovery. Provision of supportive care to homeothermic bats was sufficient for full recovery from WNS. One bat at day 70 still had both gross pathology and microscopic evidence of WNS in wing membranes and was PCR-positive for G. destructans. Dense aggregates of neutrophils surrounded the hyphae that remained in the wing membrane of this bat.

  12. Toxoplasma encephalitis in Haitian adults with acquired immunodeficiency syndrome: a clinical-pathologic-CT correlation

    The clinical data, histologic findings, and computed tomographic (CT) abnormalities in eight adult Haitians with toxoplasma encephalitis were analyzed retrospectively. Diagnosis was established by identification of Toxoplasma gondii on autopsy in five and brain biopsy in three specimens and subsequently confirmed by the immunoperoxidase method. All these patiens, six of whom had been in the United States for 24 months or less, had severe idiopathic immunodeficiency syndrome. All were lymphopenic and six were on treatment for tuberculosis when the toxoplasma encephalitis developed. All patients were studied with CT when they developed an altered mental status and fever associated with seizures and/or focal neurologic deficits. Scans before treatment showed multiple intraparenchymal lesions in seven and a single lesion in the thalamus in one. Ring and/or nodular enhancement of the lesions was found in six and hypodense areas in two. Progressions of abnormalities occurred on serial studies. These CT findings that were best shown on axial and coronal thin-section double-dose contrast studies were useful but not diagnostically pathognomonic. In patients with similar clinical presentation CT is recommended to identify focal areas of involvement and to guide brain biopsy or excision so that prompt medical thereapy of this often lethal infection can be instituted

    To better define the role of environmental factors on LDL phenotypic expression, the authors determined LDL patterns in patients with acquired immunodeficiency syndrome (AIDS), and infection characterized by hypertriglyceridemia and weight loss. Similar to previous studies, plasma triglyceride levels were increased, whereas plasma cholesterol, LDL cholesterol, and HDL cholesterol levels were decreased in the AIDS subjects compared to those in age-matched controls. The percentage of AIDS subjects with the LDL B phenotype was increased 2.5-fold, demonstrating an increased prevalence of the LDL B phenotype in an acquired form of hypertriglyceridemia. For each LDL phenotype in AIDS, serum triglyceride levels were higher than the same phenotypic pattern in controls, with the most marked elevations in triglycerides found in AIDS subjects with the LDL B phenotype. In contrast to what was observed in controls, HDL cholesterol levels were decreased in all AIDS subjects and were unrelated to LDL pattern. Total and LDL cholesterol levels were higher in controls with the LDL B phenotype than in those with the LDL A phenotype, but there was no difference in total and LDL cholesterol in AIDS subjects with LDL B compared to A. On multiple regression analysis in subjects with AIDS, plasma triglyceride levels, age, and HDL cholesterol all contribute to the occurrence of the LDL B phenotype, but elevations in plasma triglyceride levels are the strongest independent predictor. Body mass index was not a predictor of LDL B phenotype in AIDS. These results suggest that disturbances in triglyceride metabolism that are caused by AIDS lead to the appearance of the LDL subclass B phenotype and provide further evidence that environmental or disease states that perturb lipid metabolism can produce an increased prevalence of the LDL B phenotype. 35 refs., 1 fig., 5 tabs.

  14. Up-regulation of mitochondrial activity and acquirement of brown adipose tissue-like property in the white adipose tissue of fsp27 deficient mice.

    Shen Yon Toh

    Full Text Available Fsp27, a member of the Cide family proteins, was shown to localize to lipid droplet and promote lipid storage in adipocytes. We aimed to understand the biological role of Fsp27 in regulating adipose tissue differentiation, insulin sensitivity and energy balance. Fsp27(-/- mice and Fsp27/lep double deficient mice were generated and we examined the adiposity, whole body metabolism, BAT and WAT morphology, insulin sensitivity, mitochondrial activity, and gene expression changes in these mouse strains. Furthermore, we isolated mouse embryonic fibroblasts (MEFs from wildtype and Fsp27(-/- mice, followed by their differentiation into adipocytes in vitro. We found that Fsp27 is expressed in both brown adipose tissue (BAT and white adipose tissue (WAT and its levels were significantly elevated in the WAT and liver of leptin-deficient ob/ob mice. Fsp27(-/- mice had increased energy expenditure, lower levels of plasma triglycerides and free fatty acids. Furthermore, Fsp27(-/-and Fsp27/lep double-deficient mice are resistant to diet-induced obesity and display increased insulin sensitivity. Moreover, white adipocytes in Fsp27(-/- mice have reduced triglycerides accumulation and smaller lipid droplets, while levels of mitochondrial proteins, mitochondrial size and activity are dramatically increased. We further demonstrated that BAT-specific genes and key metabolic controlling factors such as FoxC2, PPAR and PGC1alpha were all markedly upregulated. In contrast, factors inhibiting BAT differentiation such as Rb, p107 and RIP140 were down-regulated in the WAT of Fsp27(-/- mice. Remarkably, Fsp27(-/- MEFs differentiated in vitro show many brown adipocyte characteristics in the presence of the thyroid hormone triiodothyronine (T3. Our data thus suggest that Fsp27 acts as a novel regulator in vivo to control WAT identity, mitochondrial activity and insulin sensitivity.

  15. Epstein-Barr virus myelitis and Castleman's disease in a patient with acquired immune deficiency syndrome: a case report

    Balderacchi Jasminka

    2011-05-01

    Full Text Available Abstract Introduction Few cases of Epstein-Barr virus myelitis have been described in the literature. Multi-centric Castleman's disease is a lymphoproliferative disorder that is well known for its associations with the human immunodeficiency virus, human herpes virus 8, and Kaposi's sarcoma. The concurrent presentation of these two diseases in a patient at the same time is extremely unusual. Case Presentation We describe the case of a 43-year-old Caucasian man with acquired immune deficiency syndrome who presented with fever, weight loss and diffuse lymphadenopathy, and was diagnosed with multi-centric Castleman's disease. He presented three weeks later with lower extremity weakness and urinary retention, at which time cerebrospinal fluid contained lymphocytic pleocytosis and elevated protein. Magnetic resonance imaging demonstrated abnormal spinal cord signal intensity over several cervical and thoracic segments, suggesting the diagnosis of myelitis. Our patient was ultimately diagnosed with Epstein-Barr virus myelitis, as Epstein-Barr virus DNA was detected by polymerase chain reaction in the cerebrospinal fluid. Conclusion To the best of our knowledge, this is the first case of multi-centric Castleman's disease followed by acute Epstein-Barr virus myelitis in a human immunodeficiency virus-infected patient. Clinicians caring for human immunodeficiency virus-infected patients should be vigilant about monitoring patients with increasing lymphadenopathy, prompting thorough diagnostic investigations when necessary.

  16. The human immunodeficiency virus preventive vaccine research at the French National Agency for acquired immunodeficiency syndrome research

    2005-02-01

    Full Text Available The human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS epidemic is of unprecedented gravity and is spreading rapidly, notably in the most disadvantaged regions of the world. The search for a preventive vaccine is thus an absolute priority. For over 10 years the French National Agency for AIDS research (ANRS has been committed to an original program combining basic science and clinical research. The HIV preventive vaccine research program run by the ANRS covers upstream research for the definition of immunogens, animal models, and clinical research to evaluate candidate vaccines. Most researchers in 2004 believe that it should be possible to obtain partial vaccine protection through the induction of a strong and multiepitopic cellular response. Since 1992, the ANRS has set up 15 phases I and II clinical trials in order to evaluate the safety and the capacity of the candidate vaccines for inducing cellular immune responses. The tested candidate vaccines were increasingly complex recombinant canarypox viruses (Alvac containing sequences coding for certain viral proteins, utilized alone or combined with other immunogens (whole or truncated envelope proteins. ANRS has also been developing an original strategy based on the utilization of lipopeptides. These comprise synthetic fragments of viral proteins associated with lipids that facilitate the induction of a cellular immune response. These approaches promptly allowed the assessment of a prime-boost strategy combining a viral vector and lipopeptides.

    Kaposi's sarcoma is frequently found in association with acquired immunodeficiency syndrome (AIDS). We report on radiotherapy for patients with AIDS-related Kaposi's sarcoma at Tokyo Metropolitan Komagome Hospital. Between April 1991 and May 1997, radiotherapy was given to 11 lesions in eight men with AIDS-related Kaposi's sarcoma to relieve their symptoms. The lesions involved the head and neck region, the legs, and the gastrointestinal tract. Radiotherapy was carried out with 4-MV photon through parallel opposed field or high energy electrons. Total doses ranged from 20 to 38 Gy, with a median of 30 Gy, delivered in 2- to 3-Gy fractions. Four patients were given other treatments prior to the radiotherapy. Acute reaction was evaluated according to the modified acute radiation morbidity scoring criteria of the Radiation Therapy Oncology Group (RTOG). Radiotherapy had relieved the symptoms in all patients at completion of this therapy. Lesions that involved the hard palate and vocal cords had completely disappeared. The lesions that received radiotherapy were controlled without symptoms until the patients died. Patients who had the head and neck region treated exhibited severe acute mucosal reaction (at a dose of 30 Gy, there was grade 2 morbidity by modified RTOG criteria, in two patients, and grade 3 in three patients) although the radiation therapy was completed for these patients. Radiotherapy promises a favorable outcome for symptom relief in AIDS-related Kaposi's sarcoma. (author)

    Purpose: The imaging characteristics of cryptococcosis in rheumatoid arthritis (RA) patients were analyzed by comparing them with those of acquired immunodeficiency syndrome (AIDS) and immunocompetent patients, and the imaging findings were correlated with pathological findings. Methods: Two radiologists retrospectively compared the computed tomographic (CT) findings of 35 episodes of pulmonary cryptococcosis in 31 patients with 3 kinds of underlying states (10 RA, 12 AIDS, 13 immunocompetent), focusing on the nature, number, and distribution of lesions. The pathological findings of 18 patients (8 RA, 2 AIDS, 8 immunocompetent) were analyzed by two pathologists, and then correlated with imaging findings. Results: The frequencies of consolidation and ground glass attenuation (GGA) were significantly higher, and the frequency of peripheral distribution was significantly lower in the RA group than in the immunocompetent group. Peripheral distribution was less common and generalized distribution was more frequent in the RA group than in the AIDS group. The pathological findings of the AIDS and immunocompetent groups reflected their immune status: There was lack of a granuloma reaction in the AIDS group, and a complete granuloma reaction in the immunocompetent group, while the findings of the RA group varied, including a complete granuloma reaction, a loose granuloma reaction and a hyper-immune reaction. Cases with the last two pathologic findings were symptomatic and showed generalized or central distribution on CT. Conclusion: Cryptococcosis in the RA group showed characteristic radiological and pathological findings compared with the other 2 groups.

    2012-06-01

    Full Text Available Acquired Immunodeficiency Syndrome (AIDS, a global disease, caused by the Human Immunodeficiency Virus (HIV is arguably the greatest health problem of this age and there is need to make first class information on the management of HIV/AIDS available through the use of Web-Based Technology. This paper examined the various ways of contacting HIV and the effort made by Information and Technology to make life easier for people living with the virus in Nigeria. Questionnaires were distributed to Doctors and people living with HIV/AIDS to access their knowledge and belief about the said disease. MySQL was used to generate the database, to store all the vital information about the patients, their Doctors and their complaints. PHP programming for the implementation of the interfaces, Dreamweaver HTML for the design of the web-based application, T-test and Microsoft Excel were used for the analysis of data collected. The study looked into the occupation, age range and the marital status of different categories of people living with the virus. It was discovered that there were quite large numbers of people who are living with the virus.

  20. The chest radiographic appearances of non-tuberculous mycobacterial pulmonary infection in patients with acquired immunodeficiency syndrome

    Objective: To study the chest radiographic appearances of the non-tuberculous mycobacterial (NTM) pulmonary infection in patients with acquired immune deficiency syndrome (AIDS). Methods: Ten patients with AIDS and NTM underwent chest X-ray radiography and 7 patients performed high-resolution CT (HRCT) scan. Chest radiographic features of' NTM in patients with AIDS were retrospectively analyzed. Results: The chest radiograph showed bilateral pulmonary involvement in 6 cases and single lung involvement in 4 cases (3 cases in the right, 1 case in the left). Patchy air space consolidation (6 cases), large consolidation (5 cases), cavitation (5 cases), small nodules (3 cases), military nodules (2 cases), linear opacity (1 cases) were demonstrated on radiography. On HRCT, air space consolidation (7 cases), small nodules (6 cases), large consolidation (5 cases) with cavitation and cylindric bronchiectasis after the absorption of consolidation, enlarged hilar and mediastinal lymph nodes (4 cases), ground-glass opacities (3 cases), military nodules and 'tree-in-bud' sign (2 case), pleural effusion (1 case), pericardial effusion (1 case) and fibrotic band (1 case) were found. Conclusion: The most common radiographic appearances of NTM in patients with AIDS are bilateral small nodules, large consolidation with cavitation and cylindric bronchiectasis, enlarged hilar and mediastinal lymph nodes.

  2. MR findings of central nervous system involvement in acquired immunodeficiency syndrome patient : a report of two cases

    Central nervous system (CNS) manifestations in acquired immunodeficiency syndrome (AIDS) patients are an early and common feature. The spectrum of AIDS-related CNS diseases are encephalitis caused by the human immunodeficiency virus(HIV) itself, opportunistic infection, infarct and malignancy. We experienced two cases of CNS involvement in AIDS and they were serologically diagnosed as HIV encephalitis and CNS toxoplasmosis, respectively. In the case of the HIV encephalitis patient, brain MRI showed a non-enhancing lesion with high signal intensity on T2WI and low signal on T1WI and there was no mass effect on the right frontal lobe, periventricular white matter, splenium of the corpus callosum or bilateral basal ganglia. In the other case of CNS toxoplasmosis, MR showed multiple nodular and rim enhanced mass lesions in the right basal ganglia, thalamus and periventricular white matter, which were of low signal intensity on T1WI and of high intensity on T2WI. We thus report the related MRI findings

    We studied whether volunteers giving blood to the Greater New York Blood Program (GNYBP) cooperated with procedures implementing public health recommendations intended to decrease the risk of acquired immunodeficiency syndrome (AIDS) transmission by blood transfusion. Predonation medical screening was expanded to exclude donors who might be ill with AIDS. To exclude possible asymptomatic carriers of the disease, members of groups at increased risk of AIDS were asked either not to give blood or to give it for laboratory studies. A confidential questionnaire, administered to all donors after medical screening, provided the vehicle for donors to advise the GNYBP whether their donation was for laboratory studies or for patient transfusion. We found that the number of male donors decreased; AIDS-related questions in medical history led to a 2 percent increase in donor rejections; 97 percent of donors said their blood could be used for transfusions; 1.4 percent said their blood could be used for laboratory studies only; and 1.6 percent did not respond. Only units designated for transfusion were released to hospitals. People who indicated that their donation was for laboratory studies had a higher prevalence of markers for hepatitis B virus and of antibodies to cytomegalovirus. White cell counts and helper/suppressor T lymphocyte ratios were not significantly different in the two groups. We conclude that volunteer donors have cooperated with the established procedures. None of the laboratory assays identified blood units donated by individuals who, based on information about AIDS high-risk groups, designated their donation for laboratory studies. PMID:3969698

  4. X-ray and CT findings of soft tissue and bone infections secondary to acquired immunodeficiency syndrome

    Objective: To summarize X-ray and CT findings of soft tissue and bone infections secondary to acquired immunodeficiency syndrome (AIDS). Methods: The data of X-ray and CT findings of soft tissue and bone infections in 18 patients with AIDS were retrospectively collected and analyzed. Results: Of 18 patients with AIDS, the CT features of soft tissue demonstrated that subcutaneous patchy high density in 1 case which considered as cellulitis, round low density lesions with ring enhancement in 6 cases which considered as soft tissue abscesses, heterogeneous density lesions with peripheral enhancement in 1 case which considered as pyomyositis. Of 18 patients with AIDS, septic arthritis was found in 4 cases involving knee lesion in 3 cases and hip lesion. In the 4 case, the X-ray films showed bony destruction in 2 cases and the CT showed bone destruction in 3 cases and arthroedema in 4 cases. Of 18 patients with AIDS, osteomyelitis was found in 9 cases of which tuberculosis was considered in. 8 cases and vertebral involvement in 6 cases. In the 9 cases, the X-ray films and CT displayed bony destruction, hyperostosis, small sequestra, and intervertebral space narrowing. Of 18 patients with AIDS, costal lesions were found in 3 cases in which the CT showed expandable bony destruction. Of 18 patients with AIDS, ilium and sacroiliac joint lesions were found in 1 case in which the X-ray films and CT showed bony destruction, sequestra, and joint widening. Of 18 patients with AIDS, chronic pyogenic osteomyelitis of femur was found in 1 case in which the X-ray films showed bony destruction, hyperostosis osteosclerosis, and periosteal reaction. Conclusion: The X-ray and CT features of soft tissue and bone infections secondary to AIDS are characterized. The X-ray and CT are useful tools to early diagnose soft tissue and bone infections secondary to AIDS. (authors)

    2008-08-01

    Full Text Available Abstract Introduction Acquired partial lipodystrophy or Barraquer-Simons syndrome is a rare form of progressive lipodystrophy. The etiopathogenesis of adipose tissue atrophy in these patients is unknown. Case presentation This is a case report of a 44-year-old woman with acquired partial lipodystrophy. To obtain insight into the molecular basis of lipoatrophy in acquired partial lipodystrophy, we examined gene expression in adipose tissue from this patient newly diagnosed with acquired partial lipodystrophy. A biopsy of subcutaneous adipose tissue was obtained from the patient, and DNA and RNA were extracted in order to evaluate mitochondrial DNA abundance and mRNA expression levels. Conclusion The expression of marker genes of adipogenesis and adipocyte metabolism, including the master regulator PPARγ, was down-regulated in subcutaneous adipose tissue from this patient. Adiponectin mRNA expression was also reduced but leptin mRNA levels were unaltered. Markers of local inflammatory status were unaltered. Expression of genes related to mitochondrial function was reduced despite unaltered levels of mitochondrial DNA. It is concluded that adipogenic and mitochondrial gene expression is impaired in adipose tissue in this patient with acquired partial lipodystrophy.

    The objective was to study changes in the occurrence of human immunodeficiency virus type 1-related Kaposi's sarcoma and the association with degree of immunodeficiency over time. Danish patients with acquired immunodeficiency syndrome (AIDS) diagnosed between 1979 and 1990 (n = 687) were followed...... developing Kaposi's sarcoma after the AIDS diagnosis. Age, antiretroviral therapy, and primary Pneumocystis carinii pneumonia prophylaxis failed to influence the development of Kaposi's sarcoma. Thus, the occurrence of Kaposi's sarcoma remained constant over time but developed later in the course of AIDS and...

  12. Differential expression profiles of microRNA in the little brown bat (Myotis lucifugus) associated with white nose syndrome affected and unaffected individuals

    Iwanowicz, D.D.; Iwanowicz, L.R.; Hitt, N.P.; King, T.L.

    2013-01-01

    First documented in New York State in 2006, white nose syndrome (WNS) quickly became the leading cause of mortality in hibernating bat species in the United States. WNS is caused by a psychrophilic fungus, Geomyces destructans. Clinical signs of this pathogen are expressed as a dusty white fungus predominately around the nose and on the wings of affected bats. Relatively new biomarkers, such as microRNAs (miRNAs) are being targeted as markers to predict the syndrome prior to the clinical manifestation. The primary objective of this study was to identify miRNAs that could serve as biomarkers and proxies of little brown bat health. Bats were collected from hibernacula that had tested positive and negative for WNS. Genetic sequencing was completed using the Ion Torrent platform. A number of miRNAs were identified from the liver as putative biomarkers of WNS. However, given the small sample size for each treatment, this data set has only coarsely identified miRNAs indicative of WNS, and further validation is required.

    1999-12-01

    The authors report two cases of bronchogenic carcinoma in patients with acquired immunodeficiency syndrome. The first patient, a ee-year-old male, developed a left hilar adenocarcinoma, with spleen and bilateral adrenal metastases. The disease progressed unfavourably, resulting in the patient's death in less than a month. The second patient, a 47-year-old male, developed a large mass in the left upper lobe, with invasion of the thoracic wall and destruction of adjacent ribs. The histopathologic study revealed a non-oat-cell carcinoma. Both patients received palliative treatment since diagnosis was established late in the course of the disease. Recent studies suggest an association between bronchogenic carcinoma and human immunodeficiency virus infection. However, an actual increase in the prevalence of bronchogenic carcinoma in HIV-positive patients remains controversial. (author)

    Paracoccidioidomycosis is a chronic granulomatous disease, caused by the Paracoccidioides brasiliensis fungus. This disease involves primarily the lungs, although disseminated forms may occur. Bone involvement is rare, and is associated to systemic disease or may present as a focal lesion. An association between paracoccidioidomycosis and the acquired immunodeficiency syndrome (AIDS) was first established in 1989. There are only a few reports on this association, and none of them was the fungus isolated from bone lesions. This is the first case report on the paracoccidioidomycosis-AIDS association in which bone lesions demonstrated infection by P. brasiliensis. The authors propose the inclusion of paracoccidioidomycosis in the differential diagnosis of lytic bone lesions in patients with AIDS and discuss the role of radiological diagnostic in this case.

  16. SLC52A3, A Brown-Vialetto-van Laere syndrome candidate gene is essential for mouse development, but dispensable for motor neuron differentiation.

    Intoh, Atsushi; Suzuki, Naoki; Koszka, Kathryn; Eggan, Kevin

    2016-05-01

    Riboflavin, also known as vitamin B2, is essential for cellular reduction-oxidation reactions, but is not readily synthesized by mammalian cells. It has been proposed that riboflavin absorption occurs through solute carrier family 52 members (SLC52) A1, A2 and A3. These transporters are also candidate genes for the childhood onset-neural degenerative syndrome Brown-Vialetto-Van Laere (BVVL). Although riboflavin is an essential nutrient, why mutations in its transporters result in a neural cell-specific disorder remains unclear. Here, we provide evidence that Slc52a3 is the mouse ortholog of SLC52A3 and show that Slc52a3 deficiency results in early embryonic lethality. Loss of mutant embryos was associated with both defects in placental formation and increased rates of apoptosis in embryonic cells. In contrast, Slc52a3 -/- embryonic stem cell lines could be readily established and differentiated into motor neurons, suggesting that this transporter is dispensable for neural differentiation and short-term maintenance. Consistent with this finding, examination of Slc52a3 gene products in adult tissues revealed expression in the testis and intestine but little or none in the brain and spinal cord. Our results suggest that BVVL patients with SCL52A3 mutations may be good candidates for riboflavin replacement therapy and suggests that either the mutations these individuals carry are hypomorphic, or that in these cases alternative transporters act during human embryogenesis to allow full-term development.

    Full Text Available Restless Legs Syndrome (RLS is a prevalent but poorly understood disorder that ischaracterized by uncontrollable movements during sleep, resulting in sleep disturbance.Olfactory memory in Drosophila melanogaster has proven to be a useful tool for the study ofcognitive deficits caused by sleep disturbances, such as those seen in RLS. A recently generatedDrosophila model of RLS exhibited disturbed sleep patterns similar to those seen in humans withRLS. This research seeks to improve understanding of the relationship between cognitivefunctioning and sleep disturbances in a new model for RLS. Here, we tested learning andmemory in wild type and dBTBD9 mutant flies by Pavlovian olfactory conditioning, duringwhich a shock was paired with one of two odors. Flies were then placed in a T-maze with oneodor on either side, and successful associative learning was recorded when the flies chose theside with the unpaired odor. We hypothesized that due to disrupted sleep patterns, dBTBD9mutant flies would be unable to learn the shock-odor association. However, the current studyreports that the recently generated Drosophila model of RLS shows successful olfactorylearning, despite disturbed sleep patterns, with learning performance levels matching or betterthan wild type flies.

  18. The application of root mean square electrocardiography (RMS ECG for the detection of acquired and congenital long QT syndrome.

    Robert L Lux

    Full Text Available BACKGROUND: Precise measurement of the QT interval is often hampered by difficulty determining the end of the low amplitude T wave. Root mean square electrocardiography (RMS ECG provides a novel alternative measure of ventricular repolarization. Experimental data have shown that the interval between the RMS ECG QRS and T wave peaks (RTPK closely reflects the mean ventricular action potential duration while the RMS T wave width (TW tracks the dispersion of repolarization timing. Here, we tested the precision of RMS ECG to assess ventricular repolarization in humans in the setting of drug-induced and congenital Long QT Syndrome (LQTS. METHODS: RMS ECG signals were derived from high-resolution 24 hour Holter monitor recordings from 68 subjects after receiving placebo and moxifloxacin and from standard 12 lead ECGs obtained in 97 subjects with LQTS and 97 age- and sex-matched controls. RTPK, QTRMS and RMS TW intervals were automatically measured using custom software and compared to traditional QT measures using lead II. RESULTS: All measures of repolarization were prolonged during moxifloxacin administration and in LQTS subjects, but the variance of RMS intervals was significantly smaller than traditional lead II measurements. TW was prolonged during moxifloxacin and in subjects with LQT-2, but not LQT-1 or LQT-3. CONCLUSION: These data validate the application of RMS ECG for the detection of drug-induced and congenital LQTS. RMS ECG measurements are more precise than the current standard of care lead II measurements.

  19. Animal models of Central Diabetes Insipidus: Human relevance of acquired beyond hereditary syndromes and the role of oxytocin.

    Bernal, Antonio; Mahía, Javier; Puerto, Amadeo

    2016-07-01

    The aim of this study was to review different animal models of Central Diabetes Insipidus, a neurobiological syndrome characterized by the excretion of copious amounts of diluted urine (polyuria), a consequent water intake (polydipsia), and a rise in the serum sodium concentration (hypernatremia). In rodents, Central Diabetes Insipidus can be caused by genetic disorders (Brattleboro rats) but also by various traumatic/surgical interventions, including neurohypophysectomy, pituitary stalk compression, hypophysectomy, and median eminence lesions. Regardless of its etiology, Central Diabetes Insipidus affects the neuroendocrine system that secretes arginine vasopressin, a neurohormone responsible for antidiuretic functions that acts trough the renal system. However, most Central Diabetes Insipidus models also show disorders in other neurobiological systems, specifically in the secretion of oxytocin, a neurohormone involved in body sodium excretion. Although the hydromineral behaviors shown by the different Central Diabetes Insipidus models have usually been considered as very similar, the present review highlights relevant differences with respect to these behaviors as a function of the individual neurobiological systems affected. Increased understanding of the relationship between the neuroendocrine systems involved and the associated hydromineral behaviors may allow appropriate action to be taken to correct these behavioral neuroendocrine deficits.

  2. Effect of traditional Chinese medicine for treating human immunodeficiency virus infections and acquired immune deficiency syndrome: Boosting immune and alleviating symptoms.

    Zou, Wen; Wang, Jian; Liu, Ying

    2016-01-01

    To respond to the human immunodeficiency virus (HIV)/acquired immune deficiency syndrome (AIDS) epidemic in China, the integration of antiretroviral therapy (ART) and traditional Chinese medicine (TCM) has important implications in health outcomes, especially in China where the use of TCM is widespread. The National Free TCM Pilot Program for HIV Infected People began in 5 provinces (Henan, Hebei, Anhui, Hubei, and Guangdong) in 2004, and quickly scaled up to 19 provinces, autonomous regions, and municipalities in China including some places with high prevalence, 26,276 adults have been treated thus far. Usually, people with HIV infection seek TCM for four main reasons: to enhance immune function, to treat symptoms, to improve quality of life, and to reduce side effects related to medications. Evidences from randomized controlled clinical trials suggested some beneficial effects of use of traditional Chinese herbal medicine for HIV infections and AIDS. More proofs from large, well-designed, rigorous trials is needed to give firm support. Challenges include interaction between herbs and antiretroviral drugs, stigma and discrimination. The Free TCM Program has made considerable progress in providing the necessary alternative care and treatment for HIV-infected people in China, and has strong government support for continued improvement and expansion, establishing and improving a work mechanism integrating Chinese and Western medicines.

    2015-01-01

    Full Text Available Background: Illness uncertainty is a source of a chronic and pervasive psychological stress for people living with human immunodeficiency virus (HIV/acquired immune deficiency syndrome (AIDS (PLWH, and largely affects their quality of life and the ability to cope with the disease. Based on the uncertainty in illness theory, the social support is one of the illness uncertainty antecedents, and influences the level of uncertainty perceived by patients. Aim: To examine uncertainty in PLWH and its correlation with social support in Iran. Materials and Methods: This cross-sectional correlational study was conducted with 80 PLWH presenting to AIDS Research Center, Tehran, Iran in 2013. The data collected using illness uncertainty and social support inventories were analyzed through Pearson′s correlation coefficient, Spearman′s correlation coefficient, and regression analysis. Results: The results showed a high level of illness uncertainty in PLWH and a negative significant correlation between perceived social support and illness uncertainty ( P = 0.01, r = -0.29. Conclusion: Uncertainty is a serious aspect of illness experience in Iranian PLWH. Providing adequate, structured information to patients as well as opportunities to discuss their concerns with other PLWH and receive emotional support from their health care providers may be worthwhile.

  5. Recursion-based depletion of human immunodeficiency virus-specific naive CD4(+) T cells may facilitate persistent viral replication and chronic viraemia leading to acquired immunodeficiency syndrome.

    Tsukamoto, Tetsuo; Yamamoto, Hiroyuki; Okada, Seiji; Matano, Tetsuro

    2016-09-01

    Although antiretroviral therapy has made human immunodeficiency virus (HIV) infection a controllable disease, it is still unclear how viral replication persists in untreated patients and causes CD4(+) T-cell depletion leading to acquired immunodeficiency syndrome (AIDS) in several years. Theorists tried to explain it with the diversity threshold theory in which accumulated mutations in the HIV genome make the virus so diverse that the immune system will no longer be able to recognize all the variants and fail to control the viraemia. Although the theory could apply to a number of cases, macaque AIDS models using simian immunodeficiency virus (SIV) have shown that failed viral control at the set point is not always associated with T-cell escape mutations. Moreover, even monkeys without a protective major histocompatibility complex (MHC) allele can contain replication of a super infected SIV following immunization with a live-attenuated SIV vaccine, while those animals are not capable of fighting primary SIV infection. Here we propose a recursion-based virus-specific naive CD4(+) T-cell depletion hypothesis through thinking on what may happen in individuals experiencing primary immunodeficiency virus infection. This could explain the mechanism for impairment of virus-specific immune response in the course of HIV infection. PMID:27515208

    1996-01-01

    This report presents systematic clinical data regarding psychiatric diagnoses, personal and family psychiatric histories, and symptomatologic aspects of 90 consecutive human immunodeficiency virus (HIV)-seropositive and acquired immune deficiency syndrome (AIDS) patients, of whom slightly less than two thirds were at risk due to intravenous drug abuse. In addition, a comparison was made between the distribution patterns of these variables at various stages of HIV illness and related at-risk behaviors. Eighty-four percent of the patients met criteria for a spectrum of DSM-III-R diagnoses (mostly affective) that were associated with high rates of affective and alcohol abuse disorders among first-degree relatives. Mood disorders did not differ significantly between the two main groups at risk (intravenous drug users [IVDUs] v others) by gender, age, or stage of illness. The overall data from the rating scales show high levels of psychic and somatic anxiety in the early stages of illness, whereas cognitive symptoms, retardation, and disorientation are dominant in later stages. A noteworthy finding in this study is that many depressed patients demonstrated current and/or past hypomanic, hyperthymic, or cyclothymic features with no evidence of brain damage detectable by computed axial tomography (CAT). These temperamental attributes, which preceded HIV infection, may have served as risk factors for both drug abuse and impulsive sexual behavior in all types of at-risk groups. PMID:8826691

  7. Behaviors Influencing Human Immunodeficiency Virus Transmission in the Context of Positive Prevention among People Living with HIV/Acquired Immunodeficiency Syndrome in Iran: A Qualitative Study

    Seyed Ramin Radfar

    2014-01-01

    Full Text Available Background: Identifying factors, which influence health behaviors is critical to designing appropriate and effective preventive programs. Human immunodeficiency virus (HIV transmission is highly related to people behaviors and understanding factors influencing healthy behaviors among Iranian people living with HIVs (PLHIVs/acquired immunodeficiency syndrome (AIDS is very important to tailor an effective response to HIV/AIDS epidemic. Methods: This study was conducted as a qualitative study by methods of focus group discussion and in-depth interview in six provinces of Iran with 64 PLHIVs to determine factors influence engagement in positive prevention. Results: Knowledge and education, feelings of responsibility and positive prevention practices were identified as the primary domains of engagement. These domains were found to be influenced by feelings of ostracism and frustration, poverty, barriers to disclosure of HIV status, access to and utilization of drug abuse treatment services and antiretroviral therapy, adherence to treatment, age, religiousness, sex work, singleness, and incarceration. Conclusions: Designing new interventions and updating current interventions directed toward the aforementioned factors should be addressed by responsible Iranian authorities in order to have a national effective response on the HIV/AIDS epidemic.

  8. Is human immunodeficiency virus/acquired immunodeficiency syndrome decreasing among Brazilian injection drug users? Recent findings and how to interpret them

    Francisco I Bastos

    2005-02-01

    Full Text Available We briefly review findings from Brazilian settings where the human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS epidemic among injection drug users (IDUs seems to be decreasing, highlighting recent findings from Rio de Janeiro and discussing methodological alternatives. Former analyses using serologic testing algorithm for recent HIV seroconversion have shown that HIV incidence has been low in IDUs recruited by two different surveys carried out in Rio, where low injection frequencies and infection rates have been found among new injectors. The proportion of AIDS cases among IDUs in Rio has been fairly modest, compared to São Paulo and especially to the southernmost states. Notwithstanding, the interpretation of findings from serial surveys constitutes a challenge, magnified in the assessment of HIV spread among IDUs due to the dynamic nature of the drug scenes and limitations of sampling strategies targeting hard-to-reach populations. Assessment of epidemic trends may profit from the triangulation of data, but cannot avert biases associated with sampling errors. Efforts should be made to triangulate data from different sources, besides exploring specific studies from different perspectives. In an attempt to further assess the observed trends, we carried out original analyses using data from Brazilian AIDS databank.

  9. Risky sexual behavior related to human immunodeficiency virus/acquired immunodeficiency syndrome among seasonal labor migrants: A cross-sectional study from far Western Region of Nepal

    Dillee Prasad Paudel

    2013-01-01

    Full Text Available Background: Human immunodeficiency virus/acquired immunodeficiency syndrome is a global public health problem; enormously affecting the national economy, social development and human rights with posing a challenge to human civilization. Seasonal labor migrants are the most at risk population for HIV/AIDS and their risky sexual behaviors exacerbate its transmission. The aim of the study was to explore the HIV/AIDS related sexual behavior of migrant workers. Materials and Methods: A cross-sectional study was carried out among 372 migrant workers backing to Nepal from Banbasa border of India-Nepal during August-October 2010. Migrants having permanent residents of far western region, Nepal were individually contacted at the entry point of Nepal and interviewed in a confidential environment after obtaining informed consent. Data were analysed using the SPSS (16.0 version. Descriptive and inferencial statistics were applied considering P 3 sex partners. Most (82.25% had vaginal sex and 43.54% reported the consistent use of condom. About 64.76% had sex after drinking alcohol. Age, education, monthly income and nature of works were significant with risky behaviors. Conclusion: Inconsistent condom use, multiple sexual partners and sex after drinking alcohol have a cumulative effect on the risk of HIV transmission.

  10. Neuroradiology of acquired immunodeficiency syndrome

    This paper discusses MRI and CT scanning in the evaluation of AIDS patients with neurological symptoms. MRI is the more sensitive of the two techniques but has poor tissue specificity. Contrast enhancement and identification of tissue calcification on CT scans may improve tissue characterization, but a specific etiological diagnosis may not be possible with either MRI or CT scanning; confirmation by biopsy or the response to treatment is often needed. The finding of multiple focal cerebral lesions on MRI and CT scans usually indicates T. gondii infection. Toxoplasmosis may, however, coexist with primary CNS lymphoma or with fungal, mycobacterial, or viral infection. The presence of a solitary focal cerebral lesion, especially on MRI scans, suggests lymphoma or infection with an agent other than T. gondii. Focal cerebral lesions show a variety of complex signal patterns on MRI and enhancement patterns on CT, none of which are specific for a single etiology. Focal lesions on MRI and CT scans are usually associated with focal neurological deficits, but a significant minority of these lesions, especially those seen on MRI scans, may cause only generalized complaints, such as headache and encephalopathy. MRI and CT are both useful for monitoring therapy and show a reduction in the size, number, and enhancement of lesions with successful treatment. The authors conclude that, owing to its greater sensitivity, MRI appears to be more useful for detecting recurrent disease

Clinical symptoms were productive cough, hemoptysis and progressive weight loss. A chest x-ray film showed a right upper lobe consolidation while the computed tomography demonstrated consolidation and areas of cavitation. The radiologic findings were unspecific. Consequently, a bronchoscopy with bronchoalveolar lavage was performed, revealing filamentous Gram-positive bacteria (Nocardia sp. Treatment with trimethoprim-sulfamethoxazole resulted in complete remission of the respiratory symptoms. The authors review the literature and discuss the main radiological features of this disease.

  12. Identical rearranged forms of JC polyomavirus transcriptional control region in plasma and cerebrospinal fluid of acquired immunodeficiency syndrome patients with progressive multifocal leukoencephalopathy.

    Fedele, Cesare Giovanni; Ciardi, Maria Rosa; Delia, Salvatore; Contreras, Gerardo; Perez, José Luis; De Oña, Maria; Vidal, Elisa; Tenorio, Antonio

    2003-10-01

    Progressive multifocal leukoencephalopathy (PML) is a fatal demyelinating disease of the central nervous system (CNS) caused by the human polyomavirus JC (JCV). JCV has a hypervariable noncoding transcriptional control region (TCR) that spans the origin of replication of the JCV genome through to the first ATG start codon for late gene transcription. The archetype form of TCR is frequently found in the urine and kidneys of healthy and immunocompromised subjects. However the rearranged forms, whose prototype is Mad-1, possibly generated by deletion and duplication of segments of the archetype sequence, are found in the brain and cerebrospinal fluid (CSF) of PML patients. In this study the authors compared JCV TCR detected in paired CSF, plasma, and urine samples of 11 acquired immunodeficiency syndrome (AIDS) patients affected by PML to try to determine where the rearranged JCV TCRs are selected. In one patient, it was also possible to amplify and sequence the TCR in the brain and lymphocytes. Moreover, in 5/11 patients, the CSF, plasma, and urine samples corresponding to 2 months after PML development were available; and in another patient, it was possible to sequence the TCR in plasma and lymphocytes sampled 8 months before the onset of PML. The presence of the same TCR sequences in all the CSF and plasma samples taken from individual patients could strengthen the hypothesis that the blood is a compartment where JCV may replicate and undergo rearrangement of the TCR. This further supports the hypothesis that JCV reaches the brain by a hematogenous route and indicates that the JCV TCR sequences detected in plasma could be used as an early marker of JCV pathogenicity before the clinical appearance of PML in immunocompromised patients.

  13. Food Security in Households of People Living With Human Immunodeficiency Virus/Acquired Immunodeficiency Syndrome: A Cross-sectional Study in a Subdivision of Darjeeling District, West Bengal

    2016-01-01

    Objectives: Human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) adversely impacts food security in households of people living with HIV/AIDS (PLWHA). Little research has focused on food insecurity among PLWHA in India. The purpose of this study was to identify the prevalence of and factors relating to food security in households of PLWHA in the Siliguri subdivision of Darjeeling, West Bengal, India. Methods: A cross-sectional community-based study was carried out among 173 PLWHA residing in Siliguri and registered at the Anti-retroviral Therapy Centre of North Bengal Medical College & Hospital. Data was collected at the household level with interviews of PLWHA using a food security survey instrument. We analyzed the associations using logistic regression. Results: The prevalence of household food security among the participants was 50.9% (88/173). Five years or more of schooling, higher socioeconomic class and males were found to be significantly associated with a higher likelihood of food security. A later stage of the disease and the presence of other family members with HIV/AIDS were significantly associated with a lower likelihood of food security. The major coping strategies to deal with food insecurity in the acute phase HIV infection included borrowing money (56.1%), followed by spousal support, loans from microfinance institutions, banks, or money lenders, borrowing food, or selling agricultural products. Conclusions: The present study revealed that only about half of households with PLWHA were food secure. Prior interventions relating to periods of food and economic crisis as well as strategies for sustaining food security and economic status are needed in this area. PMID:27499166

    paciente con síndrome de Brown-Séquard por hernia de disco cervical.This article presents a case in which Brown-Séquard syndrome resulted from a double level cervical disc herniation. A 40-year-old man without previous history of cervical pathology, presented with insidious right arm and leg paresis associated with associated with decreased pain and thermal sensitivity in the left hemibody after diving which caused indirect trauma of the cervical spine. Magnetic resonance imaging of the cervical spine showed double level disc herniation in C4-C5 and C5-6 with compression of the right half of spinal cord and hyperintensity in T2-weighted images. After a complete decompression of neural structures, a double level interbody fusion was performed. There was partial recovery of neurological status after a long period of physical therapy. Early surgical intervention and prompt rehabilitation are paramount to achieve neurological recovery in patients with Brown-Séquard syndrome resulting from a cervical disc herniation.

    Brandy Viera Valdés

    2009-04-01

    Full Text Available The acquired Long-QT Syndrome can be caused by more than 100 non anti-arrhythmic drugs. These drugs block potassium channels; particularly the IKr which extends the ventricular repolarization beyond 450 ms. This syndrome is associated with ventricular helical tachycardia that could potentially cause immediate death. We report a patient with diagnosis of leukaemia who was treated with mitoxantrone and presented syncope. The electrocardiogram showed an interval QTc of 576 ms. After an exclusion diagnosis we concluded that there could be an association with the use of this drug caused by its toxic effects for the cardiac system. Mitoxantrone interferes in ionic transportation through cellular membrane, delays the exit of potassium from the cells and acts in the functioning of ATP asa Na/K altering the ventricular repolarization; however, it is not on the list of drugs that enlarge the QT interval. Our objective with this work is to raise the interest on new reports on this subject, and to establish a more direct causal relation through the evidence derived from new experiences.

    Summary Maintenance of body temperature is essential for survival of homeotherms. Brown adipose tissue (BAT) is a specialized fat tissue that is dedicated to thermoregulation1. Due to its remarkable capacity to dissipate stored energy and its demonstrated presence in adult humans2-5, BAT holds great promise for the treatment of obesity and metabolic syndrome1. Rodent data suggest the existence of two types of brown fat cells: the constitutive BAT (cBAT), which is of embryonic origin and anato...

  3. Transcriptomic signatures in whole blood of patients who acquire a chronic inflammatory response syndrome (CIRS) following an exposure to the marine toxin ciguatoxin

    Ryan, James C.; Wu, Qingzhong; Shoemaker, Ritchie C

    2015-01-01

    Background Ciguatoxins (CTXs) are polyether marine neurotoxins found in multiple reef-fish species and are potent activators of voltage-gated sodium channels. It is estimated that up to 500,000 people annually experience acute ciguatera poisoning from consuming toxic fish and a small percentage of these victims will develop a chronic, multisymptom, multisystem illness, which can last years, termed a Chronic Inflammatory Response Syndrome (CIRS). Symptoms of ciguatera CIRS include fatigue, cog...

  4. Atmospheres of Brown Dwarfs

    Helling, Christiane

    2014-01-01

    Brown Dwarfs are the coolest class of stellar objects known to date. Our present perception is that Brown Dwarfs follow the principles of star formation, and that Brown Dwarfs share many characteristics with planets. Being the darkest and lowest mass stars known makes Brown Dwarfs also the coolest stars known. This has profound implication for their spectral fingerprints. Brown Dwarfs cover a range of effective temperatures which cause brown dwarfs atmospheres to be a sequence that gradually changes from a M-dwarf-like spectrum into a planet-like spectrum. This further implies that below an effective temperature of < 2800K, clouds form already in atmospheres of objects marking the boundary between M-Dwarfs and brown dwarfs. Recent developments have sparked the interest in plasma processes in such very cool atmospheres: sporadic and quiescent radio emission has been observed in combination with decaying Xray-activity indicators across the fully convective boundary.

    2001-12-01

    We present the main findings observed on the high-resolution computed tomography examinations of 15 patients with acquired immunodeficiency syndrome and Pneumocystis carinii pneumonia. The high-resolution computed tomography and autopsy findings of 5 patients were also compared. The most frequently observed high-resolution computed tomography patterns were ground-glass attenuation, consolidation areas, crazy-paving pattern and cysts. Nodules and intralobular reticulation were less frequently observed. Ground-glass attenuation and consolidation areas corresponded to alveolar filling with inflammatory exudate. Thickening of the interlobular septa was due to cell infiltration and edema. One patient presented interlobular reticulation, and the pathology study revealed alveolar septa thickening due to cell infiltration and fibrosis. Nodules observed in one of the patients corresponded to a patchy intra alveolar accumulation of microorganisms and inflammatory cells forming a 'granulomatous' pattern. (author)

    Full Text Available Non-Hodgkin′s lymphoma (NHL is the second most common acquired immunodeficiency syndrome (AIDS-defining cancer. In this population, up to 70-80% of cases may present as extranodal location as the primary clinical manifestation of the neoplasm disease. Gastrointestinal tract is the most frequent location of AIDS-associated NHL. However, salivary gland involvement, including the parotid gland is a rare complication in human immunodeficiency virus (HIV-patients. Here, we describe a patient seropositive for the HIV, who developed a primary NHL of the parotid gland histologically classified as a high-grade diffuse large B-cell lymphoma. Patient was treated with a combination of chemotherapy plus highly active antiretroviral therapy with a good clinical, virological and immunological response and a prolonged survival, more than 5 years, without evidence of neoplasm relapse.

  10. Knowledge, attitudes and practices regarding human immunodeficiency virus/acquired immune deficiency syndrome and sexually transmitted infections among health care providers in Lahore, Pakistan

    Human Immunodeficiency Virus (HIV) infection is a global problem of extraordinary dimensions and has so far resulted in nearly 25 million deaths worldwide. Health care providers (HCPs) are considered to play a pivotal role in the provision of preventive and curative services to individuals suffering from HIV/AIDS and sexually transmitted infections. Pakistan, which was previously categorised as having a low-prevalence, high-risk HIV epidemic, is now facing a concentrated HIV epidemic among its most at-risk populations such as injecting drug users. The objective of this study was to assess the knowledge, attitudes and reported practices relating to HIV/AIDS and STIs among private and public sector health care providers providing clinical services in areas where women sell sex. This was an exploratory quantitative study, where a structured questionnaire was administered in face-to-face interviews with 200 HCPs from the public and private sectors. Knowledge about AIDS and correct diagnosis of STIs were defined as according to the national guidelines of NACP. Pearson's chi-square analysis was performed to test associations between predictors and level of knowledge of STIs in each group separately. Multivariate logistic regression analysis was employed to indicate predicting factors for correct management of STIs. Forty-five percent of the HCPs had correct knowledge about the transmission and prevention of HIV, whereas 21% had seen a patient with advanced HIV infection, only two HCPs had been trained to manage such cases and 82% were not aware of syndromic management of STIs. Only 10% could cite the 'correct treatment' of gonorrhoea, syphilis and vaginal discharge. The odds of having the 'correct knowledge' of diagnosing gonorrhoea and syphilis were 2.1 (CI 95%, 1.2-3.8) if the HCP was a female medical doctor working in public sector. Further intensive training is needed to improve the ability of relevant HCPs to correctly diagnose and effectively treat patients

  12. Acquired causes of intestinal malabsorption.

    van der Heide, F

    2016-04-01

    This review focuses on the acquired causes, diagnosis, and treatment of intestinal malabsorption. Intestinal absorption is a complex process that depends on many variables, including the digestion of nutrients within the intestinal lumen, the absorptive surface of the small intestine, the membrane transport systems, and the epithelial absorptive enzymes. Acquired causes of malabsorption are classified by focussing on the three phases of digestion and absorption: 1) luminal/digestive phase, 2) mucosal/absorptive phase, and 3) transport phase. Most acquired diseases affect the luminal/digestive phase. These include short bowel syndrome, extensive small bowel inflammation, motility disorders, and deficiencies of digestive enzymes or bile salts. Diagnosis depends on symptoms, physical examination, and blood and stool tests. There is no gold standard for the diagnosis of malabsorption. Further testing should be based on the specific clinical context and the suspected underlying disease. Therapy is directed at nutritional support by enteral or parenteral feeding and screening for and supplementation of deficiencies in vitamins and minerals. Early enteral feeding is important for intestinal adaptation in short bowel syndrome. Medicinal treatment options for diarrhoea in malabsorption include loperamide, codeine, cholestyramine, or antibiotics. PMID:27086886

  13. Field and experimental data indicate that the eastern cottontail (Sylvilagus floridanus) is susceptible to infection with European brown hare syndrome (EBHS) virus and not with rabbit haemorrhagic disease (RHD) virus.

    2015-01-01

    The eastern cottontail (Sylvilagus floridanus) is an American lagomorph. In 1966, it was introduced to Italy, where it is currently widespread. Its ecological niche is similar to those of native rabbits and hares and increasing overlap in distribution brings these species into ever closer contact. Therefore, cottontails are at risk of infection with the two lagoviruses endemically present in Italy: Rabbit Haemorrhagic Disease virus (RHDV) and European Brown Hare Syndrome Virus (EBHSV). To verify the susceptibility of Sylvilagus to these viruses, we analyzed 471 sera and 108 individuals from cottontail populations in 9 provinces of north-central Italy from 1999 to 2012. In total, 15-20% of the cottontails tested seropositive for EBHSV; most titres were low, but some were as high as 1/1280. All the cottontails virologically tested for RHDV and EBHSV were negative with the exception of one individual found dead with hares during a natural EBHS outbreak in December 2009. The cottontail and the hares showed typical EBHS lesions, and the EBHSV strain identified was the same in both species (99.9% identity). To experimentally confirm the diagnosis, we performed two trials in which we infected cottontails with both EBHSV and RHDV. One out of four cottontails infected with EBHSV died of an EBHS-like disease, and the three surviving animals developed high EBHSV antibody titres. In contrast, neither mortality nor seroconversion was detected after infection with RHDV. Taken together, these results suggest that Sylvilagus is susceptible to EBHSV infection, which occasionally evolves to EBHS-like disease; the eastern cottontail could therefore be considered a "spill over" or "dead end" host for EBHSV unless further evidence is found to confirm that it plays an active role in the epidemiology of EBHSV.

  14. Dichoptic perception of brown.

    DeLawyer, Tanner; Morimoto, Takuma; Buck, Steven L

    2016-03-01

    Two experiments assessed mechanisms underlying brown induction by presenting a foveal target disk and concentric annular surround stimuli that varied in contrast relative to larger backgrounds. Stimuli were presented under monocular, binocular, and dichoptic viewing conditions. Observers adjusted the luminance of the target disk to a criterion brown level. We found evidence for at least two separate mechanisms for brown induction: one mechanism that is dependent on physically contiguous contrast and operates in monocular pathways and another mechanism that responds to high luminance contrast anywhere in the visual field and can operate after convergence of signals from the two eyes.

    2008-01-01

    Full Text Available Olmsted syndrome is a rare disorder characterized by the combination of periorificial, keratotic plaques and bilateral palmoplantar keratoderma. New associated features are being reported. Olmsted syndrome is particularly rare in a female patient, and we report such a case in a six year-old Indian girl, who presented with keratoderma of her soles since birth and on her palms since the age of two years along with perioral and perinasal hyperkeratosis. She had sparse, light brown, thin hair. Although the psychomotor development of the child was normal until 18 months of age, the keratoderma plaques had restricted the child′s mobility after that stage.

    2016-01-01

    Full Text Available HIV/AIDS patients often present with orogenital ulcers. In the immunocompromised patient diagnosis of these ulcers pose a challenge, as there is a myriad of etiologies. We present a case of an HIV/AIDS patient with recurrent orogenital aphthosis that was confirmed to have concomitant diagnosis of Behcet's disease. Proper awareness of the causes of these ulcers is essential for prompt and effective treatment. While rare causes may be at the bottom of a differential list in an immunocompetent host, when HIV/AIDS is involved these rare causes often percolate to the top.

  19. Acquired immunodeficiency syndrome and its ocular complications

    Rao Narsing

    1994-01-01

    Full Text Available Human immunodeficiency virus infection is the first major pandemic of the 20th century. At present, almost 10 million people are known to be infected with this virus, and it is estimated that by the year 2000, approximately 40 million people will be infected. Transmission of this deadly infection is predominantly by sexual contact. Individuals infected with this virus pass through several predictable stages with progressive decrease in circulating CD4+ T cells. During the advanced stage, these patients develop various opportunistic infections or malignancies, or both. It is this advanced stage that was first recognized as AIDS, which has a 100% mortality rate. The opportunistic organisms that can involve the eye in patients with AIDS include cytomegalovirus, herpes zoster, Toxoplasma gondii, Mycobacterium tuberculosis, Cryptococcus neoformans, Mycobacterium avium-intracellulare, Pneumocystis carinii, Histoplasma capsulatum, Candida, and others. Intraocular lesions from these agents often represent disseminated infections. Visual morbidity occurs secondary to retinitis due to cytomegalovirus, herpes zoster, or Toxoplasma gondii. Anti-viral agents such as ganciclovir or foscarnet are effective against cytomegalovirus infection. The role of the ophthalmologist in the diagnosis and management of AIDS is becoming increasingly important. Not only does the eye reflect systemic disease, but ocular involvement may often precede systemic manifestations. In the AIDS patient, the ophthalmologist thus has an opportunity to make not only a slight-saving, but also life-saving diagnosis of disseminated opportunistic infections.

    Full Text Available OBJETIVO: Analisar a freqüência da tuberculose e das outras principais doenças oportunistas definidoras de síndrome da imunodeficiência adquirida, no momento em que estes casos são notificados, no Município do Rio de Janeiro. MÉTODOS: Análise do banco de dados do Sistema de Vigilância Epidemiológica do Programa de Doenças Sexualmente Transmissíveis e Síndrome da Imunodeficiência Adquirida da Cidade do Rio de Janeiro, no período de 1993 a 2002. RESULTADOS: A expansão da definição de casos de síndrome da imunodeficiência adquirida ocorrida em 1998 criou um aumento substancial no número de casos notificados de síndrome da imunodeficiência adquirida, principalmente por aqueles que passaram a ser definidos pelo critério imunológico. Dentre os casos de síndrome da imunodeficiência adquirida que foram definidos apenas por doença, a candidíase em suas diversas formas manteve-se como a doença oportunista de maior freqüência no momento da notificação. Embora a pneumonia por Pneumocystis carinii se apresentasse como a segunda doença mais freqüente na maioria dos anos observados, a partir de 2001, a tuberculose ultrapassou-a em freqüência, tornando-se a segunda doença mais freqüente no momento da notificação dos casos de síndrome da imunodeficiência adquirida. CONCLUSÃO: Apesar da diminuição do número de casos de síndrome da imunodeficiência adquirida definidos por doença, a tuberculose manteve-se como um importante evento definidor dessa síndrome, sendo atualmente de ocorrência mais freqüente do que a pneumonia por Pneumocystis carinii e a toxoplasmose, provavelmente por sua alta taxa de prevalência na cidade.OBJECTIVE: To analyze the frequency of tuberculosis and of the other principal opportunistic infections defining acquired immunodeficiency syndrome at the time such cases were reported in the city of Rio de Janeiro, Brazil.

  3. Irradiated brown dwarfs

    Casewell, S L; Lawrie, K A; Maxted, P F L; Dobbie, P D; Napiwotzki, R

    2014-01-01

    We have observed the post common envelope binary WD0137-349 in the near infrared $J$, $H$ and $K$ bands and have determined that the photometry varies on the system period (116 min). The amplitude of the variability increases with increasing wavelength, indicating that the brown dwarf in the system is likely being irradiated by its 16500 K white dwarf companion. The effect of the (primarily) UV irradiation on the brown dwarf atmosphere is unknown, but it is possible that stratospheric hazes are formed. It is also possible that the brown dwarf (an L-T transition object) itself is variable due to patchy cloud cover. Both these scenarios are discussed, and suggestions for further study are made.

    citomegalovírus, respectivamente. O emprego da técnica de imunoistoquímica auxilia no diagnóstico das esofagites virais e torna possível detectar o citomegalovírus em esôfagos normais à endoscopia e/ou ao exame histopatológico.BACKGROUND: Almost all patients with acquired immunodeficiency virus syndrome will have gastrointestinal symptoms during the course of their illness. The high prevalence and complications of esophagitis are well documented. AIM: Graduate esophagitis; identify microorganisms like Candida sp, cytomegalovirus, herpesvirus and mycobacteria; identify by immunohistochemical staining viral agents cytomegalovirus, herpesvirus I, herpesvirus II, Epstein-Barr Virus, human papilloma virus and human immunodeficiency virus; verify how immunohistochemistry changes the profile of esophagitis; verify the association between the histological and endoscopical findings; verify the relevance of the number of fragments studied in the characterization of the histological agents. METHODS: We studied retrospectively esophageal biopsies in 227 patients with acquired immunodeficiency virus syndrome using hematoxylin and eosin, PAS (periodic acid of Schiff, Groccott and Ziehl-Nielsen stains and immunoperoxidase stains to detect opportunistic agents. Endoscopic aspects were studied. RESULTS: The non-specific esophagitis grade III, in the inferior third of the esophagus, was the most frequent type. Candida sp was the most frequent agent, followed by viruses cytomegalovirus, herpesvirus and mycobacteria. The presence of plaque and ulceration suggested the diagnosis of esophageal candidiasis and cytomegalovirus esophagitis. Immunohistochemical allowed the characterization of cytomegalovirus and of herpesvirus in those cases where other techniques could not achieve it, furthermore the cytomegalovirus was also found in histological normal cases, making the use of this technique advisable in routine diagnosis. The herpesvirus I was not found isolated but associated to

    Brown adipose tissue expends energy in the form of heat via the mitochondrial uncoupling protein UCP1. Recent studies showed that brown adipose tissue is present in adult humans and may be exploited for its anti-obesity and anti-diabetes actions. Apelin is an adipocyte-derived hormone that plays important roles in energy metabolism. Here, we report that apelin-APJ signaling promotes brown adipocyte differentiation by increasing the expressions of brown adipogenic and thermogenic transcriptional factors via the PI3K/Akt and AMPK signaling pathways. It is also found that apelin relieves the TNFα inhibition on brown adipogenesis. In addition, apelin increases the basal activity of brown adipocytes, as evidenced by the increased PGC1α and UCP1 expressions, mitochondrial biogenesis, and oxygen consumption. Finally, we provide both in vitro and in vivo evidence that apelin is able to increase the brown-like characteristics in white adipocytes. This study, for the first time, reveals the brown adipogenic and browning effects of apelin and suggests a potential therapeutic route to combat obesity and related metabolic disorders.

    While most myelodysplastic syndrome/acute myeloid leukemia cases are sporadic, rare familial cases occur and provide some insight into leukemogenesis. The most clearly defined familial cases result from inherited mutations in RUNX1 or CEBPA. Recently, novel germline mutations in GATA2 have been reported. We, therefore, investigated individuals from families with one or more first-degree relatives with myelodysplastic syndrome/acute myeloid leukemia with wild-type RUNX1 and CEBPA, for GATA2 mu...

    International audience The eastern cottontail (Sylvilagus floridanus) is an American lagomorph. In 1966, it was introduced to Italy, where it is currently widespread. Its ecological niche is similar to those of native rabbits and hares and increasing overlap in distribution brings these species into ever closer contact. Therefore, cottontails are at risk of infection with the two lagoviruses endemically present in Italy: Rabbit Haemorrhagic Disease virus (RHDV) and European Brown Hare Synd...

  17. Heyde's syndrome

    Perišić Nenad

    2006-01-01

    Full Text Available Background: Heyde's syndrome implies an association of calcified aortic stenosis with the high gradient of pressure and angiodysplasic bleeding from the digestive tract. It has been proven that in patients with this syndrome, acquired form of von Willebrand type II A develops. Replacing of aortic valves by artificial ones brings about the spontaneous retreat of coagulation disorder, and the stoppage of the digestive tract bleeding. Case report. We reported two patients with the Heyde's syndrome. In one of the patients the aortic valves were replaced by biologic valves, after which the digestive tract bleeding stopped, while the second patient was treated conservatively due to a high operation risk. Conclusion. Patients with Heyde's syndrome are a complex multidisciplinary problem, thus their adequate treatment requires a team work in order to provide the most rational type of therapy for each patient separately.

  19. Etiopathology of acquired cholesteatoma

    Prabodh Karnik

    2011-01-01

    Full Text Available The etiopathology of acquired cholesteatoma has undergone numerous changes over the past 150 years. However, certain facts stand out with clarity. The presence of cytokeratins in acquired cholesteatoma, which are akin to those found in the tympanic membrane and external auditory canal, shows that these are probably the site of origin of acquired cholesteatoma. The cholesteatoma sac also shows its greatest growth at its tympanic membrane attachment into the middle ear. Implantations of squamous epithelium due to trauma or surgery could be another originating factor. The basic pathology is the formation of papillary cones from the tympanic membrane or external auditory canal, which progress from microcholesteatoma to frank cholesteatoma with keratin collections. There is an altered matrix metalloproteinase pathway. Tumor necrosis factor activation with altered wound healing process contributes to the collateral destruction of bone. Trisomy and aneuploidy of chromosome 8 predispose to cholesteatoma formation in affected individuals. In this article, we present the etiopathology of acquired cholesteatoma as it stands today.

    2011-01-01

    Thoracic perivascular adipose tissue (PVAT) is a unique adipose depot that likely influences vascular function and susceptibility to pathogenesis in obesity and the metabolic syndrome. Surprisingly, PVAT has been reported to share characteristics of both brown and white adipose, but a detailed direct comparison to interscapular brown adipose tissue (BAT) has not been performed. Here we show by full genome DNA microarray analysis that global gene expression profiles of PVAT are virtually ident...

    Acquired cystic kidney disease (ACKD), also known as acquired renal cystic disease (ARCD,) occurs in patients who are on dialysis for end-stage renal disease. It is generally accepted that ACKD develops as a consequence of sustained uremia and can first manifest even before dialysis is initiated while the patient is still in chronic renal failure. The role of immune suppression, particularly in transplant recipients, in the development of ACKD, is still under investigation. The prevalence of ACKD is directly related to the duration of dialysis and the risk of cancer is directly related to the presence of cysts. Herein we review the current understanding of the pathophysiology and imaging implications of ACKD. (orig.)

    Brown clustering, an unsupervised hierarchical clustering technique based on ngram mutual information, has proven useful in many NLP applications. However, most uses of Brown clustering employ the same default configuration; the appropriateness of this configuration has gone predominantly...... unexplored. Accordingly, we present information for practitioners on the behaviour of Brown clustering in order to assist hyper-parametre tuning, in the form of a theoretical model of Brown clustering utility. This model is then evaluated empirically in two sequence labelling tasks over two text types. We...... explore the dynamic between the input corpus size, chosen number of classes, and quality of the resulting clusters, which has an impact for any approach using Brown clustering. In every scenario that we examine, our results reveal that the values most commonly used for the clustering are sub-optimal....

  14. Brown coal and the climate

    The undisputed aims of a sensible energy policy are safety, reasonable prices, environmental compatibility and saving resources. Each energy source and every form of energy conversion and use has specific advantages and disadvantages which must be weighed up. It is in favour of brown coal that it can succeed in international competition and therefore offers security of supply, economy, productivity and employment. The mining and use of brown coal comply with the highest environmental standards, in international comparison. Against this, mining brown coal by strip mining inevitably involves intervention in the environment and the social structure of the coalfield. Burning brown coal to generate electricity in powerstations is specifically connected with high CO2 emission. (orig.)

  16. Progress toward automatic classification of human brown adipose tissue using biomedical imaging

    Gifford, Aliya; Towse, Theodore F.; Walker, Ronald C.; Avison, Malcom J.; Welch, E. B.

    2015-03-01

    Brown adipose tissue (BAT) is a small but significant tissue, which may play an important role in obesity and the pathogenesis of metabolic syndrome. Interest in studying BAT in adult humans is increasing, but in order to quantify BAT volume in a single measurement or to detect changes in BAT over the time course of a longitudinal experiment, BAT needs to first be reliably differentiated from surrounding tissue. Although the uptake of the radiotracer 18F-Fluorodeoxyglucose (18F-FDG) in adipose tissue on positron emission tomography (PET) scans following cold exposure is accepted as an indication of BAT, it is not a definitive indicator, and to date there exists no standardized method for segmenting BAT. Consequently, there is a strong need for robust automatic classification of BAT based on properties measured with biomedical imaging. In this study we begin the process of developing an automated segmentation method based on properties obtained from fat-water MRI and PET-CT scans acquired on ten healthy adult subjects.

  1. A role of active brown adipose tissue in cancer cachexia?

    Emiel Beijer

    2012-06-01

    Full Text Available Until a few years ago, adult humans were not thought to have brown adipose tissue (BAT. Now, this is a rapidly evolving field of research with perspectives in metabolic syndromes such as obesity and new therapies targeting its bio-energetic pathways. White, brown and socalled brite adipose fat seem to be able to trans-differentiate into each other, emphasizing the dynamic nature of fat tissue for metabolism. Human and animal data in cancer cachexia to date provide some evidence for BAT activation, but its quantitative impact on energy expenditure and weight loss is controversial. Prospective clinical studies can address the potential role of BAT in cancer cachexia using 18F-fluorodeoxyglucose positron emission tomography-computed tomography scanning, with careful consideration of co-factors such as diet, exposure to the cold, physical activity and body mass index, that all seem to act on BAT recruitment and activity.

  2. MRI of fetal acquired brain lesions

    Acquired fetal brain damage is suspected in cases of destruction of previously normally formed tissue, the primary cause of which is hypoxia. Fetal brain damage may occur as a consequence of acute or chronic maternal diseases, with acute diseases causing impairment of oxygen delivery to the fetal brain, and chronic diseases interfering with normal, placental development. Infections, metabolic diseases, feto-fetal transfusion syndrome, toxic agents, mechanical traumatic events, iatrogenic accidents, and space-occupying lesions may also qualify as pathologic conditions that initiate intrauterine brain damage. MR manifestations of acute fetal brain injury (such as hemorrhage or acute ischemic lesions) can easily be recognized, as they are hardly different from postnatal lesions. The availability of diffusion-weighted sequences enhances the sensitivity in recognizing acute ischemic lesions. Recent hemorrhages are usually readily depicted on T2 (*) sequences, where they display hypointense signals. Chronic fetal brain injury may be characterized by nonspecific changes that must be attributable to the presence of an acquired cerebral pathology. The workup in suspected acquired fetal brain injury also includes the assessment of extra-CNS organs that may be affected by an underlying pathology. Finally, the placenta, as the organ that mediates oxygen delivery from the maternal circulation to the fetus, must be examined on MR images

  4. Translocations (5;17) and (7;17) in patients with de novo or therapy-related myelodysplastic syndromes or acute nonlymphocytic leukemia. A possible association with acquired pseudo-Pelger-Hut anomaly and small vacuolated granulocytes

    Twelve patients [two with de novo myelodysplastic syndrome (MDS), four with secondary MDS, five with de novo acute nonlymphocytic leukemia (ANLL), one with secondary ANLL] showed a 17p deletion resulting from translocations involving 17p: t(5;17)(p11;p11) in four cases, t(7;17)(p11;p11) in six cases, complex (5;17)(q23;p12) translocation with dicentric chromosome in one case, and t(17;?)(p11-12;?) in the remaining patient. All these structural anomalies were observed in hypodiploid clones associated with total or partial monosomy of chromosomes 5 and 7 (12 cases), monosomy 12 (five cases), monosomy 3 (four cases), and monosomy 4 (three cases). Median survival was only 3.3 months (range 3 days to 8 months). Striking features were observed in bone marrow mature granulocytes: all but one case had a pseudo-Pelger-Hut anomaly in a significant number of granulocytes, and eight patients had granulocytes with reduced size and clear cytoplasmic vacuoles. Careful cytological review of 51 patients with MDS or ANLL and various cytogenetic anomalies was performed for comparison: vacuolated granulocytes were a very uncommon finding. On the other hand, eight patients had a pseudo-Pelger-Hut anomaly, which correlated significantly with total monosomy 17 in these patients. A possible correlation between cytological anomalies and cytogenetic data is discussed, and the role of 17p in the nuclear segmentation of granulocytes is stressed

  9. [Differential diagnosis of pulmonary tuberculosis and community-acquired pneumonia].

    Deĭkina, O N; Mishin, V Iu; Demikhova, O V

    2007-01-01

    The purpose of this investigation was to enhance the efficiency of differential diagnosis of pneumonia and pulmonary tuberculosis. A hundred and fifty-nine adult patients were examined. These included 78 patients with pulmonary tuberculosis and 81 with community-acquired p neumonia. The clinical features of infiltrative pulmonary tuberculosis (n = 48) and mild community-acquired pneumonia (n = 51) were compared. The course of caseous pneumonia (n = 30) was compared with that of moderate and severe community-acquired pneumonia (n = 30). Significant differences in the manifestations of the intoxication and bronchopulmonary syndrome were not found in patients with community-acquired pneumonia and infiltrative pulmonary tuberculosis. Physical studies showed that in patients with community-acquired pneumonia, moist rale (54.9%) and crepitation (11.8%) were prevalent, but in those with infiltrative tuberculosis rale was absent in 60.4% of cases and the pattern of respiration was unchanged in 79.2%. Chest X-ray studies indicated that in patients with community-acquired pneumonia, lower lobar inflammatory changes were predominant in 62.8% of cases whereas in those with infiltrative pulmonary tuberculosis the process was mainly bilateral (43.8%) with the presence of destructive changes (83.3%) and bronchogenic dissemination (66.7%). In patients with caseous pneumonia, the intoxication syndrome was more significant than in those with severe community-acquired pneumonia. Chest X-ray studies demonstrated that in patients with caseous pneumonia, specific changes were bilateral with the involvement of 2 lobes or more, with destruction and bronchogenic dissemination while in those with community-acquired pneumonia, the pulmonary processes were predominantly bilateral (76.6%) at the lower lobar site (36.7%).

    New entrants to a market tend to be superior to incumbents in originating radical innovations. We provide a new explanation for this phenomenon, based on markets for technology. It applies in industries where successful entrepreneurial firms, or their technologies, are acquired by incumbents that...... lower probability accompanies higher value in case of success—that is, a more radical innovation. In the second stage, successful entrants bid to be acquired by the incumbent. We assume that entrants cannot survive on their own, so being acquired amounts to a prize in a contest.

  12. Novel nuances of human brown fat

    Scheele, Camilla; Larsen, Therese Juhlin; Nielsen, Søren

    2014-01-01

    There is a current debate in the literature on whether human fat derived from the supraclavicular region should be classified as brown, or as the white fat-derived less potent, brite/beige. This commentary addresses whether the existing classification defined in mice is sufficient to describe the...... types of thermogenic adipocytes in humans. We recently published a contradictory mRNA expression signature of human supraclavicular fat defined by an upregulation of the brite marker TBX1 along with the classical brown markers ZIC1 and LHX8, as well as genes indicating brown fat activity including UCP1......, there was no difference in UCP1, PGC-1α, PRDM16, suggesting both depots had equal brown fat potency. Taken together, supraclavicular brown fat derived from adult humans seems to represent a type of brown fat with distinct features from both subcutaneous white/brite and interscapular brown fat. Therefore...

  13. Myasthenic syndromes.

    Farrugia, M E

    2011-03-01

    The neuromuscular junction is vulnerable to autoimmune attack both at the pre-synaptic nerve terminal and at the post-synaptic muscle membrane. Antibodies directed to the nicotinic acetylcholine receptor at the muscle surface are the cause of myasthenia gravis in the majority of cases. Myasthenia gravis is an acquired condition, characterised by weakness and fatigability of the skeletal muscles. The ocular muscles are commonly affected first, but the disease often generalises. Treatment includes symptom control and immunosuppression. The thymus gland plays an important role in the pathogenesis of myasthenia gravis and thymectomy is indicated in certain subgroups. Lambert-Eaton myasthenic syndrome is associated with antibodies directed to the voltage-gated calcium channel antibodies at the pre-synaptic nerve terminal. It is an acquired condition and, in some cases, may be paraneoplastic, often secondary to underlying small cell lung carcinoma. Clinical presentation is distinct from myasthenia gravis, with patients often first presenting with lower limb muscle fatigability and autonomic symptoms. Congenital myasthenic syndromes are inherited neuromuscular disorders due to mutations in proteins at the neuromuscular junction. Various phenotypes exist depending on the protein mutation. Treatment is directed towards symptom control and immunosuppression is not indicated. PMID:21365067

  16. Photometric brown-dwarf classification

    Skrzypek, N

    2013-01-01

    We have developed a method "photo-type" to identify and accurately classify L and T dwarfs, onto the standard system, from photometry alone. We combine SDSS, UKIDSS and WISE data and classify point sources by comparing the izYJHKW1W2 colours against template colours for quasars, stars, and brown dwarfs. In a sample of $6.5\\times10^6$ bright point sources, J$<$17.5, from 3150 deg$^2$, we identify and type 898 L and T dwarfs, making this the largest homogeneously selected sample of brown dwarfs to date. The sample includes 713 (125) new (previously known) L dwarfs and 21 (39) T dwarfs. For the previously-known sources, the scatter in the plot of photo-type vs spectral type indicates that our photo-types are accurate to 1.5 (1.0) sub-types rms for L (T) dwarfs. Peculiar objects and candidate unresolved binaries are identified.

  17. Microlensing, Brown Dwarfs and GAIA

    Evans, N W

    2014-01-01

    The GAIA satellite can precisely measure the masses of nearby brown dwarfs and lower main sequence stars by the microlensing effect. The scientific yield is maximised if the microlensing event is also followed with ground-based telescopes to provide densely sampled photometry. There are two possible strategies. First, ongoing events can be triggered by photometric or astrometric alerts by GAIA. Second, events can be predicted using known high proper motion stars as lenses. This is much easier, as the location and time of an event can be forecast. Using the GAIA source density, we estimate that the sample size of high proper motion ($>300$ mas yr$^{-1}$) brown dwarfs needed to provide predictable events during the 5 year mission lifetime is surprisingly small, only of the order of a hundred. This is comparable to the number of high proper motion brown dwarfs already known from the work of the UKIDSS Large Area Survey and the all-sky WISE satellite. Provided the relative parallax of the lens and the angular Ein...

  3. BROWN TUMOR OF THE FACIAL BONES

    Violeta Trandafir

    2010-11-01

    Full Text Available Brown tumor arises as a direct result of the effect of parathyroid hormone on bone tissue in some patients with hyperparathyroidism. The lesion localizes in areas of intense bone resorbtion, and the bone defect becomes filled with fibroblastic tissue that can deform the bone and simulate a neoplastic process. Brown tumors can affect the mandible, maxilla, clavicle, ribs and pelvic bones. Most patients with hyperparathyroidism are asymptomatic. Skeletal changes may represent the first manifestations of the disease. Radiologically, brown tumor in the jaws presents as a well-defined radiolucent osteolytic lesion, making it hard to differentiate it from other maxillary expansive lesions that can present with a similar imaging. Brown tumors exhibit no pathognomonic histologic changes. Differentiating between a brown tumor and other giant-cell tumors may be very difficult, even with histology. A final diagnosis can be defined only by evaluating the radiological findings with histopathological, laboratory and clinical data. At present, brown tumor is considered as a reparative cellular process rather than a real neoplasia. This phenomenon is considered as pathognomonic of hyperparathyroidism secondary to renal failure, especially in patients on long-term hemodialysis. The initial treatment of brown tumor involves control of hyperparathyroidism, regardless of whether it is primary or secondary. The clinical management of brown tumor aims primarily to reduce the elevated parathyroid hormone levels by pharmacological treatment. Surgical treatment is reserved to nonresponders or to patients with painful symptomatology or alteration of normal function. Brown tumor can recur if hyperparathyroidism persists or recurs.

  4. The Engrailed-1 Gene Stimulates Brown Adipogenesis

    Chuanhai Zhang

    2016-01-01

    Full Text Available As a thermogenic organ, brown adipose tissue (BAT has received a great attention in treating obesity and related diseases. It has been reported that brown adipocyte was derived from engrailed-1 (EN1 positive central dermomyotome. However, functions of EN1 in brown adipogenesis are largely unknown. Here we demonstrated that EN1 overexpression increased while EN1 knockdown decreased lipid accumulation and the expressions of key adipogenic genes including PPARγ2 and C/EBPα and mitochondrial OXPHOS as well as BAT specific marker UCP1. Taken together, our findings clearly indicate that EN1 is a positive regulator of brown adipogenesis.

  5. Brown Fat and Browning for the Treatment of Obesity and Related Metabolic Disorders

    So Hun Kim

    2016-02-01

    Full Text Available Brown fat is a specialized fat depot that can increase energy expenditure and produce heat. After the recent discovery of the presence of active brown fat in human adults and novel transcription factors controlling brown adipocyte differentiation, the field of the study of brown fat has gained great interest and is rapidly growing. Brown fat expansion and/or activation results in increased energy expenditure and a negative energy balance in mice and limits weight gain. Brown fat is also able to utilize blood glucose and lipid and results in improved glucose metabolism and blood lipid independent of weight loss. Prolonged cold exposure and beta adrenergic agonists can induce browning of white adipose tissue. The inducible brown adipocyte, beige adipocyte evolving by thermogenic activation of white adipose tissue have different origin and molecular signature from classical brown adipocytes but share the characteristics of high mitochondria content, UCP1 expression and thermogenic capacity when activated. Increasing browning may also be an efficient way to increase whole brown fat activity. Recent human studies have shown possibilities that findings in mice can be reproduced in human, making brown fat a good candidate organ to treat obesity and its related disorders.

    Full Text Available Problem statement: incidence of abortion in the United States has steadily declined since 1990. The question is why? Approach: This study, using multiple linear regression, examines whether women’s unprotected sexual activity is deterred by the risk of contracting AIDS as reflected in decreased abortion rates. Results: The empirical evidence consistently finds that the prevalence of AIDS reduces the risky (unprotected sexual activity of women of childbearing ages 15-44 as reflected in their abortion rates. The empirical results remain robust for the abortion rates of teens ages 15-17 and for teens ages 15-19. Conclusion: The empirical results suggest that the behavioral modification induced by the prevalence of AIDS accounted for 21% of the decrease in abortion rates over the time period 1992-2005.

  13. Experimental oral polio vaccines and acquired immune deficiency syndrome.

    Hooper, E

    2001-06-29

    The simian immunodeficiency virus (SIV) of the common chimpanzee is widely acknowledged as the direct ancestor of HIV-1. There is increasing historical evidence that during the late 1950s, kidneys were routinely excised from central African chimpanzees by scientists who were collaborating with the polio vaccine research of Dr Hilary Koprowski, and sent - inter alia - to vaccine-making laboratories in the USA and Africa, and to unspecified destinations in Belgium. While there is no direct evidence that cells from these kidneys were used as a substrate for growing Dr Koprowski's oral polio vaccines, there is a startling coincidence between places in Africa where his CHAT vaccine was fed, and the first appearances in the world of HIV-1 group M and group-M-related AIDS. Because of the enormous implications of the hypothesis that AIDS may be an unintended iatrogenic (physician-caused) disease, it is almost inevitable that this theory will engender heated opposition from many of those in the scientific establishment, and those with vested interests.

    We present Atacama Large Millimeter/submillimeter Array continuum and spectral line data at 0.89 mm and 3.2 mm for three disks surrounding young brown dwarfs and very low mass stars in the Taurus star forming region. Dust thermal emission is detected and spatially resolved for all the three disks, while CO(J = 3-2) emission is seen in two disks. We analyze the continuum visibilities and constrain the disks' physical structure in dust. The results of our analysis show that the disks are relatively large; the smallest one has an outer radius of about 70 AU. The inferred disk radii, radial profiles of the dust surface density, and disk to central object mass ratios lie within the ranges found for disks around more massive young stars. We derive from our observations the wavelength dependence of the millimeter dust opacity. In all the three disks, data are consistent with the presence of grains with at least millimeter sizes, as also found for disks around young stars, and confirm that the early stages of the solid growth toward planetesimals occur also around very low-mass objects. We discuss the implications of our findings on models of solids evolution in protoplanetary disks, the main mechanisms proposed for the formation of brown dwarfs and very low-mass stars, as well as the potential of finding rocky and giant planets around very low-mass objects.

    2010-01-01

    Young Goodman Brown is one the best short fictions written by Nathaniel Hawthorne in 1835. The indirectness of the Young Goodman Brown can be seen from the produce, narration and the characteristics of the short fiction. The indirectness of expression or description leaves enough space for readers to understand the theme of the short fiction by themselves.

    Full Text Available We report two occupationally acquired cases of American cutaneous leishmaniasis (ACL: one accidental laboratory autoinoculation by contaminated needlestick while handling an ACL lesion sample, and one acquired during field studies on bird biology. Polymerase chain reaction (PCR assays of patient lesions were positive for Leishmania, subgenus Viannia. One isolate was obtained by culture (from patient 2 biopsy samples and characterized as Leishmania (Viannia naiffi through an indirect immunofluorescence assay (IFA with species-specific monoclonal antibodies (mAbs and by multilocus enzyme electrophoresis (MLEE. Patients were successfully treated with N-methyl-glucamine. These two cases highlight the potential risks of laboratory and field work and the need to comply with strict biosafety procedures in daily routines. The swab collection method, coupled with PCR detection, has greatly improved ACL laboratory diagnosis.

  4. Cogema acquires TOTAL's uranium assets

    On April 28, France's nuclear fuel cycle conglomerate Cogema and petroleum group TOTAL announced a plan in which Cogema will assume ownership of TOTAL's uranium assets worldwide, and as part of the deal, each firm will acquire shares of the other. On June 2, the agreement will be submitted to shareholders and, assuming it is approved, will go into effect this year. The agreement calls for TOTAL to acquire a 10.8-percent share in Cogema, thus becoming its first private sector shareholder, by underwriting a reserve capital increase of FF1.5 billion (approximately US$283 million). In return, Cogema will pay FF2.52 billion for approximately 4.3 percent of TOTAL, as part of a reserve capital increase totalling FF4.07 billion

    2014-12-01

    Cancer genetics has rapidly evolved in the last two decades. Understanding and exploring the several genetic pathways in the cancer cell is the foundation of targeted therapy. Several genomic aberrations have been identified and their role in carcinogenesis is being explored. In contrast to most cancers where these mutations are acquired, patients with hereditary cancer syndromes have inherited genomic aberrations. The understanding of the molecular pathobiology in hereditary cancer syndromes has advanced dramatically. In addition, many molecularly targeted therapies have been developed that could have potential roles in the treatment of patients with hereditary cancer syndromes. In this review, we outline the presentation, molecular biology, and possible targeted therapies for two of the most widely recognized hereditary cancer syndromes -- hereditary breast and ovarian cancer syndrome and hereditary non-polyposis colorectal cancer syndrome (Lynch syndrome). We will also discuss other syndromes such as familial adenomatous polyposis and Li-Fraumeni syndrome (TP53). PMID:25549704

  7. Auroral Phenomena in Brown Dwarf Atmospheres

    Pineda, J. Sebastian; Hallinan, Gregg

    2016-01-01

    Since the unexpected discovery of radio emission from brown dwarfs some 15 years ago, investigations into the nature of this emission have revealed that, despite their cool and neutral atmospheres, brown dwarfs harbor strong kG magnetic fields, but unlike the warmer stellar objects, they generate highly circularly polarized auroral radio emission, like the giant planets of the Solar System. Our recent results from Keck LRIS monitoring of the brown dwarf LSR1835+32 definitively confirm this picture by connecting the auroral radio emission to spectroscopic variability at optical wavelengths as coherent manifestations of strong large-scale magnetospheric auroral current systems. I present some of the results of my dissertation work to understand the nature brown dwarf auroral phenomena. My efforts include a survey of Late L dwarfs and T dwarfs, looking for auroral Hα emission and a concurrent survey looking for the auroral emission of H3+ from brown dwarfs with radio pulse detections. I discuss the potential connection of this auroral activity to brown dwarf weather phenomena and how brown dwarf aurorae may differ from the analogous emission of the magnetized giant planets in the Solar System.

  8. Knowledge transfer - Acquiring implicit knowledge

    Many organisations have recognised the problem of experts taking home a huge amount of specific knowledge, which they have gathered in their department, when they leave. The successor is capable only of acquiring explicit expertise because implicit experiences are not documented and therefore no more available. That is why we have started this pilot study in order to try to conserve the above mentioned tacit and implicit knowledge and to make it available to other colleagues. Using a semi-standardised interview we elicit tacit knowledge from the expert and summarise it in a report. This interview-guideline forms the basis of in-depth investigation for implicit knowledge.

    Apathy has a high prevalence and a significant contribution to treatment and rehabilitation outcomes in acquired brain damage. Research on the disorder’s neuropsychological correlates has produced mixed results. While the mixed picture may be due to the use of varied assessment tools on different patient populations, it’s also the case that most studies treat apathy as a unitary syndrome. This is in spite of evidence that apathy is a multifaceted and multidimensional syndrome. This study inve...

  11. Brown Dwarfs at the Exoplanet Mass Boundary

    Faherty, J. K.; Cruz, K. L.; Rice, E. L.; Riedel, A.

    2014-10-01

    Young brown dwarfs and directly-imaged exoplanets have enticingly similar photometric and spectroscopic characteristics, indicating that their cool, low gravity atmospheres should be studied in concert. Similarities between the peculiar shaped H band, near and mid-IR photometry as well as location on color magnitude diagrams provide important clues about how to extract physical properties of planets from current brown dwarf observations. Our team has assigned >30 brown dwarfs to 10-150 Myr nearby moving groups. In so doing, we have discovered important diversity among this extremely low-mass (10 - 30 M_{Jup}) age-calibrated sample indicating that cloud properties play a critical role in their observables.

    2013-01-01

    Young brown dwarfs and directly-imaged exoplanets have enticingly similar photometric and spectroscopic characteristics, indicating that their cool, low gravity atmospheres should be studied in concert. Similarities between the peculiar shaped H band, near and mid-IR photometry as well as location on color magnitude diagrams provide important clues about how to extract physical properties of planets from current brown dwarf observations. In this proceeding we discuss systems newly assigned to 10-150 Myr nearby moving groups, highlight the diversity of this uniform age-calibrated brown dwarf sample, and reflect on their implication for understanding current and future planetary data.

  14. Community-acquired Acinetobacter baumannii: clinical characteristics, epidemiology and pathogenesis.

    Dexter, Carina; Murray, Gerald L; Paulsen, Ian T; Peleg, Anton Y

    2015-05-01

    Community-acquired Acinetobacter baumannii (CA-Ab) is a rare but serious cause of community-acquired pneumonia in tropical regions of the world. CA-Ab infections predominantly affect individuals with risk factors, which include excess alcohol consumption, diabetes mellitus, smoking and chronic lung disease. CA-Ab pneumonia presents as a surprisingly fulminant course and is characterized by a rapid onset of fever, severe respiratory symptoms and multi-organ dysfunction, with a mortality rate reported as high as 64%. It is unclear whether the distinct clinical syndrome caused by CA-Ab is because of host predisposing factors or unique bacterial characteristics, or a combination of both. Deepening our understanding of the drivers of overwhelming CA-Ab infection will provide important insights into preventative and therapeutic strategies. PMID:25850806

  6. POST PANCREATITIS SMA SYNDROME : A CASE REPORT

    Ritesh M

    2015-05-01

    Full Text Available Superior mesenteric artery (SMA syndrome is a rare acquired disorder in which acute angulation of SMA causes compression of the third part of the duodenum between the SMA and the aorta, leading to obstruction. Loss of fatty tissue as a result of a variet y of debilitating conditions is believed to be the etiologic factor causing the acute angulation. Conditions like increased spinal lordosis, application of a body cast, short ligament of Treitz or unusually low origin of SMA may also precipitate this syndr ome. The diagnosis of SMA syndrome is based on clinical symptoms and radiologic evidence of obstruction. SMA syndrome has been described after rapid or severe weight loss in conditions such as cancer or extensive burn injuries, prolonged bed rest, anorexia , or malabsorption syndromes. Herewith we are reporting a case of post pancreatitis SMA syndrome. KEYWORDS: Post pancreatitis SMA syndrome; superior mesenteric artery syndrome; SMA syndrome.

  9. Candle power at Browns Ferry

    An account is given of the serious accident that occurred to the Browns Ferry nuclear power station in Alabama on March 22 1975, when a fire caused by an electrician searching for air leaks using a candle caused great damage to the reactor. The fire put several key safety systems out of action and caused problems in shutting down one of the plant's two reactors. The use of a candle for the purpose was regarded as a highly unofficial but time-honoured method. In this case the candle ignited polyurethane foam surrounding some electrical cables, and the fire spread back through the reactor walls. Some alarming features of the fire fighting effort are noted. The use of water finally quickly extinguished the fire. The unconventional means that had to be adopted to shut down the reactors are described. Implications of the accident for other plants are being considered and modifications are suggested. There were no adverse effects on public health and safety. (author)

  12. Obstetric antiphospholipid syndrome.

    Esteve-Valverde, E; Ferrer-Oliveras, R; Alijotas-Reig, J

    2016-04-01

    Obstetric antiphospholipid syndrome is an acquired autoimmune disorder that is associated with various obstetric complications and, in the absence of prior history of thrombosis, with the presence of antiphospholipid antibodies directed against other phospholipids, proteins called cofactors or PL-cofactor complexes. Although the obstetric complications have been related to the procoagulant properties of antiphospholipid antibodies, pathological studies of human placenta have shown the proinflammatory capacity of antiphospholipid antibodies via the complement system and proinflammatory cytokines. There is no general agreement on which antiphospholipid antibodies profile (laboratory) confers the greatest obstetric risk, but the best candidates are categories I and IIa. Combined treatment with low doses of aspirin and heparin achieves good obstetric and maternal outcomes. In this study, we also review the therapeutic possibilities in refractory cases, although the likelihood of progressing to other autoimmune diseases is low. We briefly comment on incomplete obstetric antiphospholipid syndrome, also known as antiphospholipid antibody-mediated pregnancy morbidity syndrome. PMID:26603476

  14. Infections Acquired in the Garden.

    Cunha, Cheston B; Cunha, Burke A

    2015-10-01

    Gardening is a wonderful pastime, and the garden is a very peaceful place to enjoy one's vacation. However, the garden may be a treacherous place for very young or compromised hosts when one takes into account the infectious potential residing in the soil, as well as the insect vectors on plants and animals. Even normal hosts may acquire a variety of infections from the soil, animals, or animal-related insect bites. The location of the garden, its natural animal and insect inhabitants, and the characteristics of the soil play a part in determining its infectious potential. The most important factor making the garden an infectious and dangerous place is the number and interaction of animals, whether they are pets or wild, that temporarily use the garden for part of their daily activities. The clinician should always ask about garden exposure, which will help in eliminating the diagnostic possibilities for the patient. The diagnostic approach is to use epidemiological principles in concert with clinical clues, which together should suggest a reasonable list of diagnostic possibilities. Organ involvement and specific laboratory tests help further narrow the differential diagnosis and determine the specific tests necessary to make a definitive diagnosis. PMID:26542044

    Full Text Available Kindler syndrome is a rare autosomal recessive disorder associated with skin fragility. It is characterized by blistering in infancy, photosensitivity and progressive poikiloderma. The syndrome involves the skin and mucous membrane with radiological changes. The genetic defect has been identified on the short arm of chromosome 20. This report describes an 18-year-old patient with classical features like blistering and photosensitivity in childhood and the subsequent development of poikiloderma. The differential diagnosis of Kindler syndrome includes diseases like Bloom syndrome, Cockayne syndrome, dyskeratosis congenita, epidermolysis bullosa, Rothmund-Thomson syndrome and xeroderma pigmentosum. Our patient had classical cutaneous features of Kindler syndrome with phimosis as a complication.

  16. Surface Sampler Arm Acquiring Sample

    1976-01-01

    Operation of the surface sampler in obtaining Martian soil for Viking 2's molecular analysis experiment last Saturday (September 25) was closely monitored by one of the Lander cameras because of the precision required in trenching the small area--8 by 9 inches-surrounded by rocks. Dubbed 'Bonneville Salt Flats,' the exposure of thin crust appeared unique in contrast with surrounding materials and became a prime target for organic analysis in spite of potential hazards. Large rock in foreground is 8 inches high. At left, the sampler scoop has touched the surface, missing the rock at upper left by a comfortable 6 inches, and the backhoe has penetrated the surface about one-half inch. The scoop was then pulled back to sample the desired point and (second photo) the backhoe furrowed the surface pulling a piece of thin crust toward the spacecraft. The initial touchdown and retraction sequence was used to avoid a collision between a rock in the shadow of the arm and a plate joining the arm and scoop. The rock was cleared by 2 to 3 inches. The third picture was taken 8 minutes after the scoop touched the surface and shows that the collector head has acquired a quantity of soil. With surface sampler withdrawn (right), the foot-long trench is seen between the rocks. The trench is three inches wide and about 1 1/2 to 2 inches deep. The scoop reached to within 3 inches of the rock at far end of trench. Penetration appears to have left a cavernous opening roofed by the crust and only about one inch of undisturbed crust separates the deformed surface and the rock.

  17. Brown Adipose Tissue Growth and Development

    Michael E. Symonds

    2013-01-01

    Full Text Available Brown adipose tissue is uniquely able to rapidly produce large amounts of heat through activation of uncoupling protein (UCP 1. Maximally stimulated brown fat can produce 300 watts/kg of heat compared to 1 watt/kg in all other tissues. UCP1 is only present in small amounts in the fetus and in precocious mammals, such as sheep and humans; it is rapidly activated around the time of birth following the substantial rise in endocrine stimulatory factors. Brown adipose tissue is then lost and/or replaced with white adipose tissue with age but may still contain small depots of beige adipocytes that have the potential to be reactivated. In humans brown adipose tissue is retained into adulthood, retains the capacity to have a significant role in energy balance, and is currently a primary target organ in obesity prevention strategies. Thermogenesis in brown fat humans is environmentally regulated and can be stimulated by cold exposure and diet, responses that may be further modulated by photoperiod. Increased understanding of the primary factors that regulate both the appearance and the disappearance of UCP1 in early life may therefore enable sustainable strategies in order to prevent excess white adipose tissue deposition through the life cycle.

  18. Syndrome of arachnomelia in Simmental cattle

    Weppert Myriam

    2008-10-01

    Full Text Available Abstract Background The syndrome of arachnomelia is an inherited malformation mainly of limbs, back and head in cattle. At present the arachnomelia syndrome has been well known mainly in Brown Swiss cattle. Nevertheless, the arachnomelia syndrome had been observed in the Hessian Simmental population during the decade 1964–1974. Recently, stillborn Simmental calves were observed having a morphology similar to the arachnomelia syndrome. The goal of this work was the characterization of the morphology and genealogy of the syndrome in Simmental to establish the basis for an effective management of the disease. Results The first pathologically confirmed arachnomelia syndrome-cases in the current Simmental population appeared in the year 2005. By 2007, an additional 140 calves with the arachnomelia syndrome were identified. The major pathological findings were malformed bones affecting the head, long bones of the legs and the vertebral column. It could be shown that, with the exception of two cases that were considered as phenocopies, all of the paternal and about two-third of the maternal pedigrees of the affected calves could be traced back to one common founder. Together with the data from experimental matings, the pedigree data support an autosomal recessive mutation being the etiology of the arachnomelia syndrome. The frequency of the mutation in the current population was estimated to be 3.32%. Conclusion We describe the repeated occurrence of the arachnomelia syndrome in Simmental calves. It resembles completely the same defect occurring in the Brown Swiss breed. The mutation became relatively widespread amongst the current population. Therefore, a control system has to be established and it is highly desirable to map the disease and develop a genetic test system.

  6. Brown adipogenesis of mouse embryonic stem cells in alginate microstrands

    Unser, Andrea Mannarino

    The ability of brown adipocytes (fat cells) to dissipate energy as heat shows great promise for the treatment of obesity and other metabolic disorders. Employing pluripotent stem cells, with an emphasis on directed differentiation, may overcome many issues currently associated with primary fat cell cultures. However, brown adipocytes are difficult to transplant in vivo due to the instability of fat, in terms of necrosis and neovascularization, once injected. Thus, 3D cell culture systems that have the potential to mimic adipogenic microenvironments are needed, not only to advance brown fat implantation, but also to better understand the role of brown adipocytes in treating obesity. To address this need, we created 3D "Brown-Fat-in-Microstrands" by microfluidic synthesis of alginate hydrogel microstrands that encapsulated cells and directly induced cell differentiation into brown adipocytes, using mouse embryonic stem cells (ESCs) as a model of pluripotent stem cells and brown preadipocytes as a positive control. The effect of hydrogel formation parameters on brown adipogenesis was studied, leading to the establishment of "Brown-Fat-in-Microstrands". Brown adipocyte differentiation within microstrands was confirmed by lipid droplet accumulation, immunocytochemistry and qPCR analysis of gene expression of brown adipocyte marker uncoupling protein 1 (UCP1) in addition to adipocyte marker expression. Compared to a 2D approach, 3D differentiated "Brown-Fat-in-Microstrands" exhibited higher level of brown adipocyte marker expression. The functional analysis of "Brown-Fat-in-Microstrands" was attempted by measuring the mitochondrial activity of ESC-differentiated brown adipocytes in 3D using Seahorse XF24 3 Extracellular Flux Analyzer. The ability to create "Brown-Fat-in-Microstrands" from pluripotent stem cells opens up a new arena to understanding brown adipogenesis and its implications in obesity and metabolic disorders.

    Full Text Available Introduction Acquired amegakaryocytic thrombocytopenia (AAT is a rare disease characterized by thrombocytopenia due to selective reduction/absence of bone marrow (BM megakaryocytes. In the BM culture isolated reduction of colony-forming units-megakaryocyte (CFU-Mk may occur. Material and methods BM aspirates and trephine biopsies were obtained from all patients and processed by routine methods. In vitro BM culture and cytogenetic analysis was performed in one patient. Results This article presents three patients with manifested signs of hemorrhagic syndrome due to severe thrombocytopenia caused by an absence/significant reduction of BM megakaryocytes. Eexistence of systemic or any other disease was excluded in all patients. BM culture of the second patient showed reduction of all hematopoietic progenitors. In the subsequent course of the disease in this patient, signs of dysplastic erythrocytic series and megakaryocytes were also noted, although there were no positive proofs of evolution into myelodysplastic syndrome. Discussion AAT is a disease of hematopoietic stem cells manifesting in a certain period as amegakaryocytic thrombocytopenia which subsequently may progress into aplastic anemia or myelodysplastic syndrome. Patients were treated with corticosteroids, lithium carbonate, androgens, vincristine, immunoglobulins, folic acid, platelet and erythrocyte transfusions along with plasma substitution. The first patient reacted positively to the therapy. In two other patients a minimal, short-term therapeutic effect was achieved, followed by improvement of hemorrhagic syndrome and an insignificant increase in platelet count. In one patient the treatment was stopped after 4 months and the other died of bleeding after 4 months. Conclusion AAT is a rare disease with unpredictable course. This is a case report of three patients with AAT and different therapeutic effects.

    2008-01-01

    Brown fat can increase energy expenditure and protect against obesity through a specialized program of uncoupled respiration. We show here by in vivo fate mapping that brown but not white fat cells arise from precursors that express myf5, a gene previously thought to be expressed only in the myogenic lineage. Notably, the transcriptional regulator, PRDM16 controls a bidirectional cell fate switch between skeletal myoblasts and brown fat cells. Loss of PRDM16 from brown fat precursors causes a...

    Brown fat is highly active in fuel oxidation and dissipates chemical energy through uncoupling protein 1 (UCP1)-mediated heat production. Activation of brown fat leads to increased energy expenditure, reduced adiposity, and lower plasma glucose and lipid levels, thus contributing to better homeostasis. Uncoupled respiration and thermogenesis have been considered to be responsible for the metabolic benefits of brown adipose tissue. Recent studies have demonstrated that brown adipocytes also se...

    Pseudoaminopterin syndrome or aminopterin syndrome-like sine aminopterin (ASSA syndrome--OMIM 600325] is a rare autosomal recessive syndrome defined by characteristic dysmorphic features, skeletal defects, limb anomalies, cryptorchidism, and growth retardation. The syndrome owes its name to the fact that patients resemble the children exposed to aminopterin or to methotrexate, two dihydrofolate reductase inhibitors used for chemotherapy, or as an abortificient in early pregnancy. Ten patients have been described with pseudoaminopterin syndrome. Their phenotype is variable, and differs from the phenotype resulting from folic acid deprivation, leading to the notion that the pathogenesis may be more complex than simple vitamin deficiency. We report on an Algerian patient with pseudoaminopterin syndrome, review the previously reported cases and confirm that pseudoaminopterin syndrome does not result from a detectable contiguous gene imbalance as high resolution CGH array was normal in this child.

    Alagille syndrome (OMIM 118450) is an autosomal dominant disorder associated with abnormalities of the liver, heart, eye, skeleton, and a characteristic facial appearance. Also referred to as the Alagille-Watson syndrome, syndromic bile duct paucity, and arteriohepatic dysplasia, it is a significant cause of neonatal jaundice and cholestasis in older children. In the fully expressed syndrome, affected subjects have intrahepatic bile duct paucity and cholestasis, in conjunction with cardiac ma...

  13. Paraneoplastic addisonian pigmentation and acquired ichthyosis as presenting features of multiple myeloma

    Black brown hyperpigmentation of the mucosae, sun exposed skin, palmar creases and frictional sites (Addisonian pigmentation) is characteristic of Addison disease. However, it can also occur as a para neoplastic manifestation of tumours like bronchogenic carcinoma. Acquired ichthyosis starts later in life and can also be a para neoplastic presentation.We report a unique combination of para neoplastic Addisonian pigmentation and acquired ichthyosis as presenting features in a patient with undiagnosed multiple myeloma. To the best of our knowledge this combination of para neoplastic dermatosis has not been documented before in multiple myeloma. It is concluded that the presence of more than one suspicious dermatosis may be an indicator of being para neoplastic requiring necessary work-up. (author)

  16. Morphogenetics in brown, beige and white fat development.

    Lin, Jean Z; Farmer, Stephen R

    2016-01-01

    Brown and beige (or brite) fat cells are capable of evoking non-shivering thermogenesis in response to cold and β-adrenergic stimulation. By metabolizing lipids and carbohydrate via uncoupled respiration these cells directly convert energy to heat. The discovery of brown and brown-like adipocytes in adult humans has reinvigorated interest in stimulating brown and beige fat development to combat the obesity epidemic. This review focuses on the role that cytoskeleton dynamics play in the regulation of adipocyte biology, specifically beige and brown fat development and how newly discovered adipogenic morphogens affect these processes.

  17. CHARACTERIZATION OF HOSPITAL ACQUIRED METHICILLIN RESISTANT STAPHYLOCOCCUS AUREUS

    Preethi. B.M

    2012-12-01

    Full Text Available Methicillin Resistant Staphylococcus aureus (MRSA strains have emerged as one of the most important nosocomial pathogens. The MRSA can cause a wide range of diseases, which is associated with its production to large number of extracellular toxins and other virulence factors. The diseases are toxic shock syndrome, scalded skin syndrome and food poisoning. Hospital-acquired MRSA (HA-MRSA in persons who have had frequent or recent contact with hospitals or healthcare facilities within the previous year, has recently undergone an invasive medical procedure, or is immunocompromised. Mostly HA-MRSA are transmitted most frequently through direct skin-to-skin contact or contact with shared items or surfaces that have come into contact with someone else’s colonized or infected skin. Panton Valentine Leukocidin (PVL is a biocomponent toxin has been shown to induce lysis of host defence cells. The absence of the PVL gene confirms the MRSA as HA-MRSA. Slime layer plays a remarkable role in bacterial colonization of exterior surfaces by adhesion and production of slime factor plays an important role in antibiotic resistance. Beta lactamases render bacteria resistant to beta-lactam antibiotics by hydrolyzing the beta lactam ring of penicillin’s and cephalosporins.There is a linear correlation between beta-lactamase activity and the level of resistance of bacteria to penicillins. The phage groups II and III were present in hospital acquired MRSA which colonizes on the normal skin and enter the body through cut/wound or by fracture and cause osteomyelitis and bacterial arthritis. Bacteriophage typing of MRSA strains is an epidemiological marker and is a successful method in strain characterization.

    Objective To study the presence of drug resistant mutations of protease and reverse transcriptase among human immunodeficiency virus (HIV)-1 strains isolated from treatment naive HIV/ acquired immune deficiency syndrome (AIDS) patients in Heilongjiang Province of China and to provide the baseline data for starting antiretroviral therapy in this area. Methods The protease and reverse transcriptase gene sequences were amplified by nested-polymerase chain reaction (PCR) and then sequenced. The results were compared to the subtype B consensus amino acid sequence and analyzed with Stanford HIV-db drug resistance sequence interpretation. Results The results showed that HIV strains from 49 patients were classified as subtype B'. No primary mutations associated with protease inhibitor were detected. Some secondary mutations associated with protease inhibitor were detected, which included V77I(91.5%), L63P(76.6%), I93L(74.5%), E35D(61.7%), R57K (19.1%), R41K(10.6%), A71V(8.5%), M36I(8.5%), L10I(6.4%), D60E(6.4%), L89M (4.2%) and G16E(2. 1%). Only one case had a primary mutation M184I that was associated with resistance to reverse transcriptase inhibitors. However, many secondary mutations associated with resistance to reverse transcriptase inhibitors were found, including I135L/T/R/V(81.8%), V106I(22.7%), V179D/E(11.4%), R211K(9.1%), L214F(4.5%), V189I(4.5%) and V108I(2. 3%).Conclusions The prevalence of genotypic anti-HIV drug resistance is very low in treatment naive HIV/AIDS patients in Heilongjiang Province. However, closely monitoring on drug resistance mutation is very important for preventing the development and prevalence of multi-drug resistant or cross drug resistant HIV.%目的 对黑龙江省流行的HIV-1毒株的蛋白酶基因及反转录酶基因进行基因型耐药分析,为开展大规模临床抗病毒治疗提供本底数据.方法 采用套式-PCR法扩增黑龙江省内49例HIV-1感染者及AIDS患者外周血单个核细胞中前病毒cDNA的部分

  1. The Schnitzler syndrome

    Lipsker Dan

    2010-12-01

    Full Text Available Abstract The Schnitzler syndrome is a rare and underdiagnosed entity which is considered today as being a paradigm of an acquired/late onset auto-inflammatory disease. It associates a chronic urticarial skin rash, corresponding from the clinico-pathological viewpoint to a neutrophilic urticarial dermatosis, a monoclonal IgM component and at least 2 of the following signs: fever, joint and/or bone pain, enlarged lymph nodes, spleen and/or liver, increased ESR, increased neutrophil count, abnormal bone imaging findings. It is a chronic disease with only one known case of spontaneous remission. Except of the severe alteration of quality of life related mainly to the rash, fever and pain, complications include severe inflammatory anemia and AA amyloidosis. About 20% of patients will develop a lymphoproliferative disorder, mainly Waldenström disease and lymphoma, a percentage close to other patients with IgM MGUS. It was exceedingly difficult to treat patients with this syndrome until the IL-1 receptor antagonist anakinra became available. Anakinra allows a complete control of all signs within hours after the first injection, but patients need continuous treatment with daily injections. In many aspects, the Schnitzler syndrome resembles the genetically determined auto-inflammatory syndromes involving activating mutations of the NLRP3 inflammasome. This latter point and its consequences will be addressed.

    We report on 3 brothers with growth and mental retardation, bifrontal narrowness, short palpebral fissures, deeply set eyes with entropion, wide bulbous nose, small mouth, myopia, and spastic diplegia. The patients were born to normal and non-consanguineous parents. The similarity of our cases with those recently reported by Brooks et al. supports their suggestion that these patients are representative of a distinct entity. 8 refs., 3 figs., 1 tab.

  3. Streptoccocus pyogenes: a forgotten cause of severe community-acquired pneumonia.

    Birch, C; Gowardman, J

    2000-02-01

    We report a case of severe community-acquired pneumonia caused by Streptococcus pyogenes (Lancefield Group A streptoccocus) that was complicated by a streptococcal toxic shock syndrome. Although this micro-organism is an uncommon cause of community-acquired pneumonia, previously well individuals may be infected and the clinical course may be fulminant. A household contact was the likely point of infection. Invasive group A streptococcal disease continues to remain an important cause of morbidity and mortality in the community and therefore will continue to be encountered by intensive care physicians. Treatment of Group A streptococcal infection remains penicillin; however, clindamycin should be added in severe infection. PMID:10701045

  4. Diel resource partitioning among juvenile Atlantic Salmon, Brown Trout, and Rainbow Trout during summer

    Johnson, James H.; McKenna Jr, James E.

    2015-01-01

    Interspecific partitioning of food and habitat resources has been widely studied in stream salmonids. Most studies have examined resource partitioning between two native species or between a native species and one that has been introduced. In this study we examine the diel feeding ecology and habitat use of three species of juvenile salmonids (i.e., Atlantic Salmon Salmo salar, Brown Trout Salmo trutta, and Rainbow Trout Oncorhynchus mykiss) in a tributary of Skaneateles Lake, New York. Subyearling Brown Trout and Rainbow Trout fed more heavily from the drift than the benthos, whereas subyearling Atlantic Salmon fed more from the benthos than either species of trout. Feeding activity of Atlantic Salmon and Rainbow Trout was similar, with both species increasing feeding at dusk, whereas Brown Trout had no discernable feeding peak or trough. Habitat availability was important in determining site-specific habitat use by juvenile salmonids. Habitat selection was greater during the day than at night. The intrastream, diel, intraspecific, and interspecific variation we observed in salmonid habitat use in Grout Brook illustrates the difficulty of acquiring habitat use information for widespread management applications.

    Mutations in BSCL2/SEIPIN cause Berardinelli-Seip congenital lipodystrophy type 2 (BSCL2), but the mechanisms whereby Bscl2 regulates adipose tissue function are unclear. Here, we generated adipose tissue (mature) Bscl2 knockout (Ad-mKO) mice, in which Bscl2 was specifically ablated in adipocytes of adult animals, to investigate the impact of acquired Bscl2 deletion on adipose tissue function and energy balance. Ad-mKO mice displayed reduced adiposity and were protected against high fat diet-induced obesity, but not insulin resistance or hepatic steatosis. Gene expression profiling and biochemical assays revealed increased lipolysis and fatty acid oxidation in white adipose tissue (WAT) and brown adipose tissue , as well as browning of WAT, owing to induction of cAMP/protein kinase A signaling upon Bscl2 deletion. Interestingly, Bscl2 deletion reduced food intake and downregulated adipose β3-adrenergic receptor (ADRB3) expression. Impaired ADRB3 signaling partially offsets upregulated browning-induced energy expenditure and thermogenesis in Ad-mKO mice housed at ambient temperature. However, this counter-regulatory response was abrogated under thermoneutral conditions, resulting in even greater body mass loss in Ad-mKO mice. These findings suggest that Bscl2 regulates adipocyte lipolysis and β-adrenergic signaling to produce complex effects on adipose tissues and whole-body energy balance. PMID:26269358

  6. A Very Cool Pair of Brown Dwarfs

    2011-03-01

    Observations with the European Southern Observatory's Very Large Telescope, along with two other telescopes, have shown that there is a new candidate for the coldest known star: a brown dwarf in a double system with about the same temperature as a freshly made cup of tea - hot in human terms, but extraordinarily cold for the surface of a star. This object is cool enough to begin crossing the blurred line dividing small cold stars from big hot planets. Brown dwarfs are essentially failed stars: they lack enough mass for gravity to trigger the nuclear reactions that make stars shine. The newly discovered brown dwarf, identified as CFBDSIR 1458+10B, is the dimmer member of a binary brown dwarf system located just 75 light-years from Earth [1]. The powerful X-shooter spectrograph on ESO's Very Large Telescope (VLT) was used to show that the composite object was very cool by brown dwarf standards. "We were very excited to see that this object had such a low temperature, but we couldn't have guessed that it would turn out to be a double system and have an even more interesting, even colder component," said Philippe Delorme of the Institut de planétologie et d'astrophysique de Grenoble (CNRS/Université Joseph Fourier), a co-author of the paper. CFBDSIR 1458+10 is the coolest brown dwarf binary found to date. The dimmer of the two dwarfs has now been found to have a temperature of about 100 degrees Celsius - the boiling point of water, and not much different from the temperature inside a sauna [2]. "At such temperatures we expect the brown dwarf to have properties that are different from previously known brown dwarfs and much closer to those of giant exoplanets - it could even have water clouds in its atmosphere," said Michael Liu of the University of Hawaii's Institute for Astronomy, who is lead author of the paper describing this new work. "In fact, once we start taking images of gas-giant planets around Sun-like stars in the near future, I expect that many of them

    2008-12-15

    Brown tumor is a histologically benign lesion that is a serious complication of renal osteodystrophy because it may result in severe deformity and discomfort. We report a case of brown tumor, which occurred in a 35-year-old woman with chronic renal failure, who had been treated with hemodialysis for 14 years. The lesion was found on the lingual side of the mandible. Standard panoramic radiograph showed generally decreased bone mineral density, loss of lamina dura, and thin cortical plates. Computed tomography (CT) revealed multilocular expansible lesions with heterogeneous attenuation in the anterior mandible, as well as generalized trabecular alteration with homogeneous sclerosis, and thinning or obliteration of cortical plates. Excision of the mandibular lesion and curettage of the affected bone were performed.

  11. Recommendations related to Browns Ferry Fire

    Based on its review of the events transpiring before, during and after the Browns Ferry fire, the Review Group concludes that the probability of disruptive fires of the magnitude of the Browns Ferry event is small, and that there is no need to restrict operation of nuclear power plants for public safety. However, it is clear that much can and should be done to reduce even further the likelihood of disabling fires and to improve assurance of rapid extinguishment of fires that occur. Consideration should be given also to features that would increase further the ability of nuclear facilities to withstand large fires without loss of important functions should such fires occur. The Review Group believes that improvements, especially in the areas of fire prevention and fire control, can and should be made in most existing facilities

  12. How Glassy States Affect Brown Carbon Production?

    2015-12-01

    Secondary organic material (SOM) can become light-absorbing (i.e. brown carbon) via multiphase reactions with nitrogen-containing species such as ammonia and amines. The physical states of SOM, however, potentially slow the diffusion of reactant molecules in organic matrix under conditions that semisolids or solids prevail, thus inhibiting the browning reaction pathways. In this study, the physical states and the in-particle diffusivity were investigated by measuring the evaporation kinetics of both water and organics from aromatic-derived SOMs using a quartz-crystal-microbalance (QCM). The results indicate that the SOMs derived from aromatic precursors toluene and m-xylene became solid (glassy) and the in particle diffusion was significantly impeded for sufficiently low relative humidity ( urban atmospheres that ultimately influence the climate and tropospheric photochemistry.

  14. Temporal course of motor recovery after Brown-Sequard spinal cord injuries.

    Little, J W; Halar, E

    1985-02-01

    Recovery of voluntary motor function after incomplete spinal cord injuries is attributed to a variety of physiological mechanisms, such as resolution of conduction block in injured axons, and neuroplasticity mechanisms in spared axons. To better understand these recovery mechanisms, we have examined motor recovery in one type of incomplete cord injury, the Brown-Sequard Syndrome. This syndrome is observed in patients with unilateral injury of the spinal cord and is manifested as asymmetric weakness and pain/temperature sensory loss contralateral to the weakest extremity. We have followed the course of motor recovery in two patients and reviewed the literature in an additional 59. Common features of this motor recovery include: 1) recovery of ipsilateral proximal extensor muscles before ipsilateral distal flexors, 2) recovery of any weakness in the extremity with pain/temperature sensory loss before the opposite extremity, and 3) recovery of voluntary motor strength and a functional gait by 1 to 6 months. We discuss these observations with respect to three hypotheses to explain motor recovery and suggest that neuroplasticity mechanisms functioning in spared descending axons may mediate much of the observed recovery after Brown-Sequard cord lesions.

    2012-01-01

    Non-shivering thermogenesis in brown adipose tissue (BAT) plays an important role in thermoregulation. In addition, activations of BAT have important implications for energy homeostasis due to the metabolic consumption of energy reserves entailed in the production of heat in this tissue. In this conceptual overview we describe the role of orexins/hypocretins within the central nervous system in the modulation of thermogenesis in BAT under several physiological conditions. Within this framewor...

  3. Cytoplasmic inheritance of organelles in brown algae.

    Motomura, Taizo; Nagasato, Chikako; Kimura, Kei

    2010-03-01

    Brown algae, together with diatoms and chrysophytes, are a member of the heterokonts. They have either a characteristic life cycle of diplohaplontic alternation of gametophytic and sporophytic generations that are isomorphic or heteromorphic, or a diplontic life cycle. Isogamy, anisogamy and oogamy have been recognized as the mode of sexual reproduction. Brown algae are the characteristic group having elaborated multicellular organization within the heterokonts. In this study, cytoplasmic inheritance of chloroplasts, mitochondria and centrioles was examined, with special focus on sexual reproduction and subsequent zygote development. In oogamy, chloroplasts and mitochondria are inherited maternally. In isogamy, chloroplasts in sporophyte cells are inherited biparentally (maternal or paternal); however, mitochondria (or mitochondrial DNA) derived from the female gamete only remained during zygote development after fertilization. Centrioles in zygotes are definitely derived from the male gamete, irrespective of the sexual reproduction pattern. Female centrioles in zygotes are selectively broken down within 1-2 h after fertilization. The remaining male centrioles play a crucial role as a part of the centrosome for microtubule organization, mitosis, determination of the cytokinetic plane and cytokinesis, as well as for maintaining multicellularity and regular morphogenesis in brown algae.

    2015-05-01

    Salsalate improves glucose intolerance and dyslipidemia in type 2 diabetes patients, but the mechanism is still unknown. The aim of the current study was to unravel the molecular mechanisms involved in these beneficial metabolic effects of salsalate by treating mice with salsalate during and after development of high-fat diet-induced obesity. We found that salsalate attenuated and reversed high-fat diet-induced weight gain, in particular fat mass accumulation, improved glucose tolerance, and lowered plasma triglyceride levels. Mechanistically, salsalate selectively promoted the uptake of fatty acids from glycerol tri[(3)H]oleate-labeled lipoprotein-like emulsion particles by brown adipose tissue (BAT), decreased the intracellular lipid content in BAT, and increased rectal temperature, all pointing to more active BAT. The treatment of differentiated T37i brown adipocytes with salsalate increased uncoupled respiration. Moreover, salsalate upregulated Ucp1 expression and enhanced glycerol release, a dual effect that was abolished by the inhibition of cAMP-dependent protein kinase (PKA). In conclusion, salsalate activates BAT, presumably by directly activating brown adipocytes via the PKA pathway, suggesting a novel mechanism that may explain its beneficial metabolic effects in type 2 diabetes patients.

    Humic acid derived from brown coal, with added calcium, when applied to the soil surface, can increase pH deeper into the soil profile. The humates can move down with water percolating the soil. As they move down the added calcium bound to the humate's cation exchange sites (the acidic oxygen functional groups) can exchange with toxic aluminium ions and ions on exchange sites in the soil. Thus the soil pH is buffered, nutrient transport to plants assisted, and phytotoxic aluminium bound and rendered harmless to plants. K Humate is a commercially available source of humate (ex HRL Agriculture Pty Ltd Australia) derived from brown coal. It can be obtained by the treatment of brown coal with potassium hydroxide. Calsulmag is a commercial treated coal fly ash (also ex HRL Agriculture Pty Ltd) which can be used instead of lime due to its high inorganic calcium and magnesium content. When K humate and Calsulmag are combined in an aqueous mixture, and applied to the surface of an acidic soil, pH is increased (from 3.8 to 4.5) as is exchangeable calcium (30-50%), while exchangeable aluminium is decreased (30-50%), down to a 5 cm depth.

  8. Cannabidiol promotes browning in 3T3-L1 adipocytes.

    Parray, Hilal Ahmad; Yun, Jong Won

    2016-05-01

    Recruitment of the brown-like phenotype in white adipocytes (browning) and activation of existing brown adipocytes are currently being investigated as a means to combat obesity. Thus, a wide variety of dietary agents that contribute to browning of white adipocytes have been identified. The present study was designed to investigate the effects of cannabidiol (CBD), a major nonpsychotropic phytocannabinoid of Cannabis sativa, on induction of browning in 3T3-L1 adipocytes. CBD enhanced expression of a core set of brown fat-specific marker genes (Ucp1, Cited1, Tmem26, Prdm16, Cidea, Tbx1, Fgf21, and Pgc-1α) and proteins (UCP1, PRDM16, and PGC-1α). Increased expression of UCP1 and other brown fat-specific markers contributed to the browning of 3T3-L1 adipocytes possibly via activation of PPARγ and PI3K. In addition, CBD increased protein expression levels of CPT1, ACSL, SIRT1, and PLIN while down-regulating JNK2, SREBP1, and LPL. These data suggest possible roles for CBD in browning of white adipocytes, augmentation of lipolysis, thermogenesis, and reduction of lipogenesis. In conclusion, the current data suggest that CBD plays dual modulatory roles in the form of inducing the brown-like phenotype as well as promoting lipid metabolism. Thus, CBD may be explored as a potentially promising therapeutic agent for the prevention of obesity. PMID:27067870

    2006-02-01

    Full Text Available The Metabolic syndrome is a widely prevalent and multi-factorial disorder. The syndrome has been given several names, including- the metabolic syndrome, the insulin resistance syndrome, the plurimetabolic syndrome, and the deadly quartet. With the formulation of NCEP/ATP III guidelines, some uniformity and standardization has occurred in the definition of metabolic syndrome and has been very useful for epidemiological purposes. The mechanisms underlying the metabolic syndrome are not fully known; however resistance to insulin stimulated glucose uptake seems to modify biochemical responses in a way that predisposes to metabolic risk factors. The clinical relevance of the metabolic syndrome is related to its role in the development of cardiovascular disease. Management of the metabolic syndrome involves patient-education and intervention at various levels. Weight reduction is one of the main stays of treatment. In this article we comprehensively discuss this syndrome- the epidemiology, pathogenesis, clinical relevance and management. The need to do a comprehensive review of this particular syndrome has arisen in view of the ever increasing incidence of this entitiy. Soon, metabolic syndrome will overtake cigarette smoking as the number one risk factor for heart disease among the US population. Hardly any issue of any primary care medical journal can be opened without encountering an article on type 2 diabetes, dyslipidemia or hypertension. It is rare to see type 2 diabetes, dyslipidemia, obesity or hypertension in isolation. Insulin resistance and resulting hyperinsulinemia have been implicated in the development of glucose intolerance (and progression to type 2 diabetes, hypertriglyceridemia, hypertension, polycystic ovary yndrome, hypercoagulability and vascular inflammation, as well as the eventual development of atherosclerotic cardiovascular disease manifested as myocardial infarction, stroke and myriad end organ diseases.

  4. Generalised Brown Clustering and Roll-up Feature Generation

    Derczynski, Leon; Chester, Sean

    2016-01-01

    Brown clustering is an established technique, used in hundreds of computational linguistics papers each year, to group word types that have similar distributional information. It is unsupervised and can be used to create powerful word representations for machine learning. Despite its improbable...... success relative to more complex methods, few have investigated whether Brown clustering has really been applied optimally. In this paper, we present a subtle but profound generalisation of Brown clustering to improve the overall quality by decoupling the number of output classes from the computational...... active set size. Moreover, the generalisation permits a novel approach to feature selection from Brown clusters: We show that the standard approach of shearing the Brown clustering output tree at arbitrary bitlengths is lossy and that features should be chosen instead by rolling up Generalised Brown...

  6. Wilkie's Syndrome or Superior Mesenteric Artery Syndrome: Fact or Fantasy?

    Zaraket, Vera; Deeb, Liliane

    2015-01-01

    Superior mesenteric artery (SMA) syndrome (known as Wilkie's syndrome) is a rare cause of upper gastrointestinal obstruction. It is an acquired disorder in which acute angulation of the SMA causes compression of the third part of the duodenum between the SMA and the aorta. This is commonly due to loss of fatty tissue as a result of a variety of debilitating conditions. We report a 17-year-old female who presented with intermittent abdominal pain and intractable vomiting following significant weight loss after hospitalization for pneumonia. Symptoms persisted for 2 years and the patient underwent extensive invasive and non-invasive tests, but to no avail. Thereafter she developed acute high intestinal obstruction, which unraveled her diagnosis. This case emphasizes the challenges in the diagnosis of SMA syndrome and the need for increased awareness of this entity. This will improve early recognition in order to reduce irrelevant tests and unnecessary treatments. PMID:26120301

    Brown fat cells are specialized to dissipate energy and can counteract obesity; however, the transcriptional basis of their determination is largely unknown. We show here that the zinc-finger protein PRDM16 is highly enriched in brown fat cells compared to white fat cells. When expressed in white fat cell progenitors, PRDM16 activates a robust brown fat phenotype including induction of PGC-1α, UCP1 and type 2 deiodinase expression, and a remarkable increase in uncoupled respiration.

    Brown adipocytes are a specialized cell type that is critical for adaptive thermogenesis, energy homeostasis, and metabolism. In response to cold, both classical brown fat and the newly identified “beige” or “brite” cells are activated by β-adrenergic signaling and catabolize stored lipids and carbohydrates to produce heat via UCP1. Once thought to be non-existent in adults, recent studies have discovered active classical brown and beige fat cells in humans, thus reinvigorating interest in br...

  9. Systemic Lupus Erythematosus and Antiphospholipid Syndrome

    Aleksandra Plavsic

    2014-09-01

    Full Text Available Antiphospholipid syndrome is an autoimmune disorder defined as association of vascular thrombosis and/or pregnancy complications with presence of antiphospholipid antibodies (lupus anticoagulant, anticardiolipin and anti-β2 glycoprotein I. It is the most common cause of acquired thrombophilia, and can occur as an independent entity or in relation with other diseases, especially systemic lupus erythematosus. Presence of antiphospholipid syndrome in systemic lupus erythematosus is additional vaso occlusive factor in already present inflammation, bringing further risk for thrombotic events. Clinical and serological manifestations of antiphospholipid syndrome and systemic lupus erythematosus are very similar, so possible connection for these two autoimmune disorders is assumed.

  10. Acquired angioedema secondary to hormone replacement therapy

    Malani Kumar

    2005-10-01

    Full Text Available Angioedema is a potentially life threatening condition and may be either inherited or acquired. The latter is rare with only a handful of cases reported in the world literature. Presenting complaints are often vague. Those most commonly described include swelling in the subcutaneous and submucosal tissues. Patients presenting with laryngeal edema have high mortality, and high clinical suspicion is necessary to avoid instrumentation, which can precipitate laryngeal spasm. We present a review of reported cases of hormonally induced hereditary angioedema, along with a report of a patient with acquired angioedema secondary to hormone replacement therapy. To the best of our knowledge, this case probably represents the first reported case of acquired angioedema secondary to hormone replacement therapy.

  12. Obituary: Beth Brown (1969-2008)

    Bregman, Joel

    2011-12-01

    The astronomical community lost one of its most buoyant and caring individuals when Beth Brown died, unexpectedly, at the age of 39 from a pulmonary embolism. Beth Brown was born in Roanoke, Virginia where she developed a deep interest in astronomy, science, and science fiction (Star Trek). After graduating as the valedictorian of William Fleming High School's Class of 1987, she attended Howard University, where she graduated summa cum laude in 1991 with a bachelor's degree in astrophysics. Following a year in the graduate physics program at Howard, she entered the graduate program in the Department of Astronomy at the University of Michigan, the first African-American woman in the program. She received her PhD in 1998, working with X-ray observations of elliptical galaxies from the Röntgen Satellite (ROSAT; Joel Bregman was her advisor). She compiled and analyzed the first large complete sample of such galaxies with ROSAT and her papers in this area made an impact in the field. Following her PhD, Beth Brown held a National Academy of Science & National Research Council Postdoctoral Research Fellowship at NASA's Goddard Space Flight Center. Subsequently, she became a civil servant at the National Space Science Data Center at GSFC, where she was involved in data archival activities as well as education and outreach, a continuing passion in her life. In 2006, Brown became an Astrophysics Fellow at GSFC, during which time she worked as a visiting Assistant Professor at Howard University, where she taught and worked with students and faculty to improve the teaching observatory. At the time of her death, she was eagerly looking forward to a new position at GSFC as the Assistant Director for Science Communications and Higher Education. Beth Brown was a joyous individual who loved to work with people, especially in educating them about our remarkable field. Her warmth and openness was a great aid in making accessible explanations of otherwise daunting astrophysical

    2014-11-20

    In recent years, brown dwarfs have been extended to a new Y-dwarf class with effective temperatures colder than 500 K and masses in the range of 5-30 Jupiter masses. They fill a crucial gap in observable atmospheric properties between the much colder gas-giant planets of our own solar system (at around 130 K) and both hotter T-type brown dwarfs and the hotter planets that can be imaged orbiting young nearby stars (both with effective temperatures in the range of 1500-1000 K). Distance measurements for these objects deliver absolute magnitudes that make critical tests of our understanding of very cool atmospheres. Here we report new distances for nine Y dwarfs and seven very late T dwarfs. These reveal that Y dwarfs do indeed represent a continuation of the T-dwarf sequence to both fainter luminosities and cooler temperatures. They also show that the coolest objects display a large range in absolute magnitude for a given photometric color. The latest atmospheric models show good agreement with the majority of these Y-dwarf absolute magnitudes. This is also the case for WISE0855-0714, the coldest and closest brown dwarf to the Sun, which shows evidence for water ice clouds. However, there are also some outstanding exceptions, which suggest either binarity or the presence of condensate clouds. The former is readily testable with current adaptive optics facilities. The latter would mean that the range of cloudiness in Y dwarfs is substantial with most hosting almost no clouds—while others have dense clouds, making them prime targets for future variability observations to study cloud dynamics.

  3. Categorical perception for red and brown.

    Witzel, Christoph; Gegenfurtner, Karl R

    2016-04-01

    Recent studies suggest that the widely accepted evidence in support of categorical perception of color may be a confound of effects due to low-level sensory mechanisms that are unrelated to color categories. To reveal genuine category effects, we investigated the category boundary least prone to spurious effects of low-level mechanisms: the boundary between red and brown. We tested for low-level sensory and high-level cognitive effects of categories on color discrimination, while carefully controlling potential factors of color vision that are not related to color categories. First, we established the red-brown boundary through a naming task and measured just-noticeable differences (JNDs) for colors across the boundary. If low-level sensitivity to color differences was categorical, JNDs should decrease toward the boundary. However, this was not the case. Second, we measured performance in terms of response times and error rates in a speeded discrimination task with color pairs that were equalized in discriminability based on the empirical JNDs. There was a boost of performance (lower response times and error rates) for identifying color differences in equally discriminable color pairs, when the colors crossed the boundary. Given the particularity of the red-brown boundary, these results prove that the observed effects were due to color categories rather than low-level visual mechanisms. These findings support the idea that category effects are due to a shift of attention to the linguistic distinction between categories, rather than being a pure product of perception. These category effects do not depend on the hemispheric lateralization of language. (PsycINFO Database Record PMID:26569337

  4. Multimodality cardiac imaging in Turner syndrome.

    Mortensen, Kristian H; Gopalan, Deepa; Nørgaard, Bjarne L; Andersen, Niels H; Gravholt, Claus H

    2016-06-01

    Congenital and acquired cardiovascular diseases contribute significantly to the threefold elevated risk of premature death in Turner syndrome. A multitude of cardiovascular anomalies and disorders, many of which deleteriously impact morbidity and mortality, is frequently left undetected and untreated because of poor adherence to screening programmes and complex clinical presentations. Imaging is essential for timely and effective primary and secondary disease prophylaxis that may alleviate the severe impact of cardiovascular disease in Turner syndrome. This review illustrates how cardiovascular disease in Turner syndrome manifests in a complex manner that ranges in severity from incidental findings to potentially fatal anomalies. Recommendations regarding the use of imaging for screening and surveillance of cardiovascular disease in Turner syndrome are made, emphasising the key role of non-invasive and invasive cardiovascular imaging to the management of all patients with Turner syndrome.

  5. Ageing and Brugada syndrome: considerations and recommendations

    Pieter G. Postema; Hanno L Tan; Arthur AM Wilde

    2013-01-01

    Brugada syndrome is an inherited disease associated with an increased risk of lethal ventricular arrhythmias. Such arrhythmias stem from innate disruptions in cardiac electrophysiology. Typically, such arrhythmias occur in the third or fourth decade of life. However, Brugada syndrome may also affect geriatric patients. In this paper, we focus on the ageing patient with Brugada syndrome, and specifically, on the interaction between Brugada syndrome and the more usually acquired clinical problems that may occur with increasing age, such as the use of cardiovascular and non-cardiovascular drugs, or the need for surgery. Such common conditions may also disrupt cardiac electrophysiology, thereby conferring added risk for Brugada syndrome patients. We present some considerations and recommendations that may serve as guidance to address these complexities.

  8. Analysis of Brown camera distortion model

    Nowakowski, Artur; Skarbek, Władysław

    2013-10-01

    Contemporary image acquisition devices introduce optical distortion into image. It results in pixel displacement and therefore needs to be compensated for many computer vision applications. The distortion is usually modeled by the Brown distortion model, which parameters can be included in camera calibration task. In this paper we describe original model, its dependencies and analyze orthogonality with regard to radius for its decentering distortion component. We also report experiments with camera calibration algorithm included in OpenCV library, especially a stability of distortion parameters estimation is evaluated.

  9. Human brown fat and obesity: methodological aspects

    WouterDavidVan Marken Lichtenbelt

    2011-10-01

    Full Text Available Much is known about brown adipose tissue in rodents. Its function is to generate heat in response to low environmental temperatures and to diet or overfeeding. The knowledge about BAT in humans is still rather limited despite the recent rediscovery of its functionality in adults. This review highlights the information available on the contribution of BAT in increasing human energy expenditure in relation to obesity. Besides that methodological aspects will be discussed that need special attention in order to unravel the heat producing capacity of human BAT, the recruitment of the tissue and its functionality.

  1. The Luminosities of the Coldest Brown Dwarfs

    Tinney, C G; Kirkpatrick, J Davy; Cushing, Mike; Morley, Caroline V; Wright, Edward L

    2014-01-01

    In recent years brown dwarfs have been extended to a new Y-dwarf class with effective temperatures colder than 500K and masses in the range 5-30 Jupiter masses. They fill a crucial gap in observable atmospheric properties between the much colder gas-giant planets of our own Solar System (at around 130K) and both hotter T-type brown dwarfs and the hotter planets that can be imaged orbiting young nearby stars (both with effective temperatures of in the range 1500-1000K). Distance measurements for these objects deliver absolute magnitudes that make critical tests of our understanding of very cool atmospheres. Here we report new distances for nine Y dwarfs and seven very-late T dwarfs. These reveal that Y dwarfs do indeed represent a continuation of the T dwarf sequence to both fainter luminosities and cooler temperatures. They also show that the coolest objects display a large range in absolute magnitude for a given photometric colour. The latest atmospheric models show good agreement with the majority of these ...

  2. Chandra Captures Flare From Brown Dwarf

    2000-07-01

    The first flare ever seen from a brown dwarf, or failed star, was detected by NASA's Chandra X-ray Observatory. The bright X-ray flare has implications for understanding the explosive activity and origin of magnetic fields of extremely low mass stars. Chandra detected no X-rays at all from LP 944-20 for the first nine hours of a twelve hour observation, then the source flared dramatically before it faded away over the next two hours. "We were shocked," said Dr. Robert Rutledge of the California Institute of Technology in Pasadena, the lead author on the discovery paper to appear in the July 20 issue of Astrophysical Journal Letters. "We didn't expect to see flaring from such a lightweight object. This is really the 'mouse that roared.'" Chandra LP 944-20 X-ray Image Press Image and Caption The energy emitted in the brown dwarf flare was comparable to a small solar flare, and was a billion times greater than observed X-ray flares from Jupiter. The flaring energy is believed to come from a twisted magnetic field. "This is the strongest evidence yet that brown dwarfs and possibly young giant planets have magnetic fields, and that a large amount of energy can be released in a flare," said Dr. Eduardo Martin, also of Caltech and a member of the team. Professor Gibor Basri of the University of California, Berkeley, the principal investigator for this observation, speculated that the flare "could have its origin in the turbulent magnetized hot material beneath the surface of the brown dwarf. A sub-surface flare could heat the atmosphere, allowing currents to flow and give rise to the X-ray flare -- like a stroke of lightning." LP 944-20 is about 500 million years old and has a mass that is about 60 times that of Jupiter, or 6 percent that of the Sun. Its diameter is about one-tenth that of the Sun and it has a rotation period of less than five hours. Located in the constellation Fornax in the southern skies, LP 944-20 is one of the best studied brown dwarfs because it is

  3. Kounis syndrome.

    Ntuli, P M; Makambwa, E

    2015-10-01

    Kounis syndrome is characterised by a group of symptoms that manifest as unstable vasospastic or non-vasospastic angina secondary to a hypersensitivity reaction. It was first described by Kounis and Zavras in 1991 as the concurrence of an allergic response with an anaphylactoid or anaphylactic reaction and coronary artery spasm or even myocardial infarction. Since then, this condition has evolved to include a number of mast cell activation disorders associated with acute coronary syndrome. There are many triggering factors, including reactions to multiple medications, exposure to radiological contrast media, poison ivy, bee stings, shellfish and coronary stents. In addition to coronary arterial involvement, Kounis syndrome comprises other arterial systems with similar physiologies, such as mesenteric and cerebral circulation resulting in ischaemia/infarction of the vital organs. The incidence of this condition is difficult to establish owing to the number of potential instigating factors and its relatively infrequent documentation in the literature.We report the case of an HIV-negative 39-year-old man with no coronary risk factors or family history of premature coronary artery disease, who developed Kounis syndrome after the administration of fluoroquinolone for dysuria. However, to the best of our knowledge,no data on the incidence and prevalence of Kounis syndrome in South Africa have ever been reported in the literature. The recent understanding of Kounis syndrome has led to the condition being classified into three syndrome variants. PMID:26636160

  4. The role of lipids in nonenzymatic browning

    Zamora, Rosario

    2000-04-01

    Full Text Available The role of lipids in nonenzymatic browning is studied by reviewing oxidized lipid/protein reactions in comparison with other reactions where the production of browning is known: the Maillard reaction, the ascorbic acid browning, and the quinone/amine reactions. The mechanisms proposed in these reactions for production of color and fluorescence, as well as the formation of melanoidins, lipofuscins, and low molecular weight colored products are discussed comparatively, concluding that the role of lipids in these reactions does not seem to be very different to the role of carbohydrates in the Maillard reaction or the phenols in the enzymatic browning. These carbonyl-amine reactions seem to be a group of gradual, partially reversible, universal, and inevitable side reactions in both food and biological systems. However, most of these results were obtained in model systems and additional studies should be carried out in systems closer to real foods or living beings, which should provide a more complete understanding of nonenzymatic browning, and, therefore, to afford a much more comprehensive knowledge of food and human biochemistry.En este trabajo se hace una revisión del papel de los lípidos en el pardeamiento no enzimático de alimentos mediante el estudio de las reacciones proteína/lípido oxidado en comparación con otras reacciones donde ocurre también este oscurecimiento: la reacción de Maillard, el pardeamiento producido por el ácido ascórbico, y las reacciones de las quinonas con los grupos amino. Los mecanismos propuestos para estas reacciones de producción de color y fluorescencia, así como la formación de melanoidinas, lipofuscinas y productos coloreados de bajo peso molecular son discutidos de forma comparada, concluyendo que el papel de los lípidos en estas reacciones no parece ser muy diferente del papel de los carbohidratos en el Maillard o de los fenoles en el pardeamiento enzimático.

  6. Neuroacanthocytosis Syndromes

    Walker Ruth H

    2011-10-01

    Full Text Available Abstract Neuroacanthocytosis (NA syndromes are a group of genetically defined diseases characterized by the association of red blood cell acanthocytosis and progressive degeneration of the basal ganglia. NA syndromes are exceptionally rare with an estimated prevalence of less than 1 to 5 per 1'000'000 inhabitants for each disorder. The core NA syndromes include autosomal recessive chorea-acanthocytosis and X-linked McLeod syndrome which have a Huntington´s disease-like phenotype consisting of a choreatic movement disorder, psychiatric manifestations and cognitive decline, and additional multi-system features including myopathy and axonal neuropathy. In addition, cardiomyopathy may occur in McLeod syndrome. Acanthocytes are also found in a proportion of patients with autosomal dominant Huntington's disease-like 2, autosomal recessive pantothenate kinase-associated neurodegeneration and several inherited disorders of lipoprotein metabolism, namely abetalipoproteinemia (Bassen-Kornzweig syndrome and hypobetalipoproteinemia leading to vitamin E malabsorption. The latter disorders are characterized by a peripheral neuropathy and sensory ataxia due to dorsal column degeneration, but movement disorders and cognitive impairment are not present. NA syndromes are caused by disease-specific genetic mutations. The mechanism by which these mutations cause neurodegeneration is not known. The association of the acanthocytic membrane abnormality with selective degeneration of the basal ganglia, however, suggests a common pathogenetic pathway. Laboratory tests include blood smears to detect acanthocytosis and determination of serum creatine kinase. Cerebral magnetic resonance imaging may demonstrate striatal atrophy. Kell and Kx blood group antigens are reduced or absent in McLeod syndrome. Western blot for chorein demonstrates absence of this protein in red blood cells of chorea-acanthocytosis patients. Specific genetic testing is possible in all NA syndromes

  9. Race to the Top: Transiting Brown Dwarfs and Hot Jupiters

    Beatty, Thomas G.

    2015-12-01

    There are currently twelve known transiting brown dwarfs, nine of which orbit single main-sequence stars. These systems give us one of the only ways in which we may directly measure the masses and radii brown dwarfs, which in turn provides strong constraints on theoretical models of brown dwarf interiors and atmospheres. In addition, the transiting brown dwarfs allow us to forge a link between our understanding of transiting hot Jupiters, and our understanding of the field brown dwarf population. Comparing the two gives us a unique avenue to explore the role and interaction of surface gravity and stellar irradiation in the atmospheres of sub-stellar objects. It also allows us to leverage the detailed spectroscopic information we have for field brown dwarfs to interpret the broadband colors of hot Jupiters. This provides us with insight into the L/T transition in brown dwarfs, and the atmospheric chemistry changes that occur in hot Jupiter atmospheres as they cool. I will discuss recent observational results, with a particular focus on the transiting brown dwarf KELT-1b, and suggest how more of these important systems may be discovered in the future.

  4. [Heptopulmonary syndrome].

    Cuadrado, Antonio; Díaz, Ainhoa; Iruzubieta, Paula; Salcines, José Ramón; Crespo, Javier

    2015-01-01

    Hepatopulmonary syndrome is characterized by the presence of liver disease, pulmonary vascular dilatations, and arterial hypoxemia. It is usually associated with cirrhosis of any origin, but has been described in other liver diseases, both acute and chronic, and not always associated with portal hypertension. The gold standard method to detect pulmonary vascular dilations is contrast enhancement echocardiography with saline and is essential for the diagnosis of hepatopulmonary syndrome. These dilatations reflect changes in the pulmonary microvasculature (vasodilatation, intravascular monocyte accumulation, and angiogenesis) and induce a ventilation/perfusion mismatch, or even true intrapulmonary shunts, which eventually trigger hypoxemia. This syndrome worsens patients' prognosis and impairs their quality of life and may lead to the need for liver transplantation, which is the only effective and definitive treatment. In this article, we review the etiological, pathophysiological, clinical and therapeutic features of this syndrome. PMID:25840463

    The DIDMOAD or so called Wolfram syndrome is a hereditary disease with autosomal-recessive transmission showing 4 main features: diabetes mellitus, diabetes insipidus, nervus opticus atrophia and deafness. Beside this it shows multiple organ involvement. Our 38-year old male patient, showing all above mentioned features except deafness had urinary tract involvement and neurological symptoms. EEG, cerebral MRI, tests with evoked potentials and HLA-typing were performed to discuss the aetiopathogenetic background in our patient. Almost all symptoms of the Wolfram syndrome can be mixed up with complications of diabetes mellitus, which is usually the first symptom of the Wolfram syndrome. Because of this, wrong diagnosis is not rare. Hence in differential diagnosis in any diabetes mellitus type I patient, the possibility of the Wolfram syndrome should be discussed. PMID:8023526
