Miliary tuberculosis with cerebral, liver, prostate and retroesophageal involvement.

Miliary tuberculosis results from the lymphohematogenous spread of Mycobacterium tuberculosis and it is a rare form of this disease. The most affected places are the lymph nodes, pleura, and osteoarticular system, but any organ can be involved. Currently the disease is still endemic in developing countries by its close association with poor living conditions and malnutrition. Other comorbidities, particularly infection by human immunodeficiency virus (HIV), diabetes mellitus, smoking and alcoholism are of great importance in the epidemiology of this disease. The authors describe the case of an adult man from Guinea-Bissau that has been residing in Portugal for the last few months, admitted with complaints of headache. He was submitted to a computerized tomography (CT) scan of the brain which showed multiple lesions. This led to further study and the diagnosis of a disseminated tuberculosis with cerebral, liver, prostate and retroesophageal involvement. He was started on anti-tuberculosis therapy, achieving good results.

Cytomegalic hepatitis in a patient receiving omalizumab.

Cytomegalovirus is a double stranded DNA virus that can be present in nearly all organs and body fluids. The primary infection is usually asymptomatic in the immunocompetent host and it is common among adolescents and young adults. The symptomatic form appears, in the majority of cases, as a mononucleosis syndrome with full recovery without specific treatment. We report a case of a 25 years old woman who presented with hepatitis due to CMV infection and history of omalizumab administration one month earlier. This recombinant monoclonal antibody is used to control refractory asthma and chronic spontaneous urticarial as it inhibits human IgE. Despite that, the long course of the disease lead us to initiate treatment with valganciclovir. The improvement after that was rapid and complete.

The early days of pandemic (H1N1) 2009 virus infection in the central region of Portugal.

BACKGROUND: The first case of pandemic (H1N1) 2009 virus infection was diagnosed in the central region of Portugal on June 16, 2009, in a woman infected in Canada. METHODS: The aim of our study was, first to characterize the clinical and epidemiologic aspects of all the patients with clinical manifestations included in the definition of case for investigation with samples submitted to diagnosis of the pandemic (H1N1) 2009 virus infection, in the central region of Portugal; second to assess the precision of the case definition of case for investigation considered in the study according to the presence or the absence of fever at the moment of clinical observation. We reviewed the medical records of all the patients presenting with Influenza like-illness classified as case for investigation and the first cases of patients infected with the new pandemic (H1N1) 2009 virus, diagnosed in the central region of Portugal during the pandemic period between June and August, 2009, were analyzed. Real-time reverse-transcriptase polymerase-chain-reaction (RT-PCR) testing was used to confirm the pandemic (H1N1) 2009 virus infection. Data collection was performed on a standardized paper format in agreement with the General Health Directorate. RESULTS AND DISCUSSION: Pandemic (H1N1) 2009 virus infection was confirmed in 255 patients. Overall, median age was 23 years and 42.7 % were included in the category of 20 to 29 years. Confirmed infection in patients with less than 2 years or greater than 50 years was a rare event. The first cases were imported from Europe, namely France, Spain and England. On a second phase, pandemic (H1N1) 2009 virus infection was acquired in the south of Portugal (Algarve), before de diagnosis of the first domestic case. The incidence rate for pandemic (H1N1) 2009 virus infection was 10.7 per 100,000 persons and was different according to the district. It was higher in the district of Coimbra and Guarda were the main roads connecting to Europe are. The median calculated incubation period for the for pandemic (H1N1) 2009 virus infection was 2 days. The length of the clinical manifestations until the patients look for medical observation had a median time of 2 days. All the cases were of mild to moderate severity. No deaths were observed. CONCLUSIONS: The early days of pandemic (H1N1) 2009 virus infection was mild in our region. Most affected patients were young adults, with the extreme categories ages of life being spared. Early detection and diagnosis, combined with stringent isolation and treatment procedures could have slowed the spread of the infection in our region.
