- Cervical abscess in an immunocompetent patient with Mycobacterium malmoense pulmonary diseasePublication . Duarte, JN; Marques, N; Barroso, L; Ramos, I; Sá, R; Sanz, D; Ferreira, A; Saraiva da Cunha, JGBACKGROUND: Mycobacterium malmoense is a nontuberculous mycobacteria seen mainly in two age groups and with different clinical presentations. Most patients are male adults presenting clinical symptoms and signs similar to those of pulmonary tuberculosis. The second group is formed by immunocompetent children with localized cervical lymphadenitis. Although cervical adenitis is the main extrapulmonary manifestation of M. malmoense, virtually all cases of cervical disease were documented in children. Disseminated disease is rare and has been reported in patients with severely impaired immunity. CASE REPORT: We report a case of a 47-year-old immunocompetent man with a cervical abscess, in whom we identified a M. malmoense pulmonary disease with multiple cervical, thoracic and abdominal adenopathies. CONCLUSION: Extrapulmonary infection due to M. Malmoense needs to be considered on the differential diagnosis of cervical masses and adenopathies, not only in pediatric patients but also in adults with no impaired immunity. A high index of suspicion for nontuberculous mycobacteria is essential for the diagnosis and prognosis.

- Leishmaniose visceral e infecção por vírus da imunodeficiência humana na era da terapêutica anti-retrovírica de alta eficáciaPublication . Marques, N; Cabral, S; Sá, R; Coelho, F; Oliveira, J; Saraiva da Cunha, JG; Meliço-Silvestre, AVisceral Leishmaniasis is an endemic infection in Portugal, as well as in other Mediterranean basin countries, where it has become a frequent complication of HIV infection. There are several studies published about Leishmania/HIV co-infection, however some particularities of its epidemiology, pathogenesis and especially of its treatment and prophylaxis remain unclear and undefined. The authors review some aspects of this co-infection, particularly epidemiology, clinical classic manifestations and laboratory features, diagnosis, treatment, prophylaxis and prevention and report the casuistic of the Infectious Diseases Department of the University Hospital of Coimbra during the last ten years (1996-2006) in the HAART (<>) era. Visceral Leishmaniasis behaves as an opportunistic infection in HIV-infected patients and should be considered as an AIDS-defining disease. Nowadays and according to World Health Organization, VL is the second most important protozoan disease and one of the most neglected; therefore the establishment of treatment and prophylaxis guidelines is urgent.
- Spondylodiscitis associated with recurrent Serratia bacteremia due to a transjugular intrahepatic portosystemic shunt (TIPS): a case reportPublication . Marques, N; Sá, R; Coelho, F; Saraiva da Cunha, JG; Meliço-Silvestre, AWe report a case of spondylodiscitis caused by multiresistant Serratia marcescens in a cirrhotic patient who had several Serratia bacteremias after the placement of a transjugular intrahepatic portosystemic shunt (TIPS) device. We concluded that an endovascular stent that can not be removed makes management of recurrent bacteremia difficult. Furthermore, back pain due to bacteremia is indicative of spondylodiscitis. Serratia marcescens can be an aggressive pathogen, causing spinal infection.
