This study traces the rhythms of news storytelling on Twitter via the #egypt hashtag. Using computational discourse analysis, we examine news values and the form of news exhibited in #egypt from January 25 to February 25, 2011, pre-and post-resignation of Hosni Mubarak. Results point to a hybridity of old and newer news values, with emphasis on the drama of instantaneity, the crowdsourcing of elites, solidarity, and ambience. The resulting stream of news combines news, opinion, and emotion to the point where discerning one from the other is difficult and doing so misses the point. We offer a theory of affective news to explain the distinctive character of content produced by networked publics in times of political crisis.
Scholars have been increasingly concerned with portrayals of terrorism in mainstream and alternative media outlets following the September 11 and subsequent terrorist attacks in the United Kingdom and Spain. Communication researchers have examined public response and reaction to terrorist attacks, definitions of terrorism, policy questions, media portrayals of terrorism, and framing across different media and nations. This study undertakes a comparative framing analysis of media coverage of terrorism, as reported by prominent U.S. and U.K. newspapers, combining quantitative and qualitative methods. Findings revealed that the U.S. papers engaged in more episodic coverage and the U.K. papers in more thematic coverage of terrorism and terrorism-related events. The U.S. papers were consumed with presenting news associated with the military approach, whereas the U.K. papers were oriented toward diplomatic evaluations of terrorist events.
Objectives: To review the literature on diseases linked with infection by human T-cell lymphotropic virus type I (HTLV-I) in childhood and adolescence, with focus on clinical aspects, diagnosis, pathogenesis, progression and treatment.Sources: Medical literature published during the last 20 years identified using PubMed and MEDLINE and from specialized medical books, with emphasis on infective dermatitis associated with HTLV-I (IDH), on the juvenile form of HTLV-associated myelopathy/tropical spastic paraparesis (HAM/TSP), on adult T-cell leukemia/lymphoma (ATL) and on HTLV-I-associated uveitis. Keywords used to search databases were: HTLV-I-associated infective dermatitis, HTLV-Iassociated myelopathy/tropical spastic paraparesis, adult T-cell leukemia/lymphoma, HTLV-I-associated uveitis.Summary of the findings: IDH is a chronic, relapsing and infected dermatitis of childhood which always involves the scalp and which may progress to HAM/TSP and ATL. HAM/TSP is a chronic and incapacitating myelopathy of adults. There are 17 well-documented cases of HAM/TSP in children and adolescents in the literature, 12 of whom are patients with IDH. In contrast with the adult form of the disease, the juvenile form is rapid and progressive. ATL is a type of T-cell leukemia/ lymphoma that affects adults and is generally fatal. Eleven of the 24 published reports of ATL in children and adolescents were diagnosed in Brazil.Conclusions: These diseases are likely to be more common in childhood and adolescence than the literature would suggest. It is advisable that serological testing be performed for HTLV-I in children and adolescents suffering from chronic and relapsing eczema, with signs and symptoms of myelopathy or with a diagnosis of T-cell leukemia/lymphoma. It is important that pediatricians know how to recognize the pediatric manifestations of this infection in order to correctly diagnose them and offer their patients appropriate guidance and treatment.
Skin lesions are frequent in human T-cell lymphotropic virus type 1 (HTLV-1) infection and may constitute an alert for the diagnosis of this condition. The most severe skin diseases related to this virus are adult T-cell leukemia/lymphoma (ATLL), an aggressive form of leukemia/lymphoma that fails to respond to chemotherapy, and infective dermatitis associated with HTLV-1 (IDH), a severe and recurrent form of eczema occurring in childhood. ATLL affects the skin in 43-72% of cases. In this review, the clinical, histopathological and immunohistochemical aspects of ATLL and IDH will be discussed, as well as the differential diagnoses, giving particular focus to the primary cutaneous ATLL. IDH may progress to HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP) and to ATLL. Adult onset IDH and reactional and inflammatory dermatoses found in carriers and also in patients with HAM/TSP will be considered. Other dermatological diseases that occur more frequently in HTLV-1-infected individuals such as xerosis, acquired ichthyosis, seborrheic dermatitis and infectious and parasitic dermatoses will also be discussed.
Psoriasis is a systemic, chronic, immunologically mediated disease, with significant genetic and environmental influences. It affects from 1 to 3% of the world population. Recently, the relation between psoriasis and different comorbidities, particularly metabolic syndrome, has become extremely relevant. Uveitis is characterized by a process of intraocular inflammation resulting from various causes. Considering psoriasis and uveitis as immune-mediated diseases, this study aims to evaluate the possible association of psoriasis and/or psoriatic arthritis with uveitis and its subtypes. Few studies have evaluated the association of uveitis and psoriasis without joint involvement. It seems that psoriasis without arthropathy is not a risk factor for the development of uveitis. Uveitis tends to develop more frequently in patients with arthropathy or pustular psoriasis than in patients with other forms of psoriasis. Ophthalmic examination should be performed periodically in patients with psoriasis and uveitis. If ophthalmopathy is diagnosed, the patient should receive adequate treatment with anti-inflammatory drugs or immunomodulators to prevent vision loss.

Methods: A total of 13 patients with chronic Chagas disease were treated with benznidazole (5mg/kg/day/60 days) and surveyed via antibody measurement and conventional electrocardiogram over the course of 4 years. Results: The antibody titers were signifi cantly reduced after 4 years (p<0.05). Most of the patients showed maintenance of the initial clinical picture (electrocardiographic), with the exception of 4 cases. Conclusions: Although trypanocidal therapy in the chronic phase of Chagas disease was of limited effectiveness, we believe that it is benefi cial in treating these patients.
According to the WHO, sexual health is not merely the absence of disease. Sexual dysfunction may be present in 40.8% of psoriasis patients, furthermore, 68% prevalence was found in Brazilian women with psoriasis. The moderate prevalence of psoriatic lesions in the genital area (35%–42%) does not explain the alarming prevalence of sexual dysfunction. Other factors, such as anxiety, depression, and also psoriasis treatment may contribute to its development. Likewise, atherosclerosis of the pelvic vasculature is involved in the pathogenesis of erectile dysfunction. Risk factors for erectile dysfunction tend to be confused with the comorbidities seen in psoriasis patients. We also highlight that it may serve as a marker of cardiovascular risk.
