Linezolid has been used in the treatment of multidrug-resistant/extensively drug-resistant tuberculosis in adults with encouraging results, however experience in children is scarce. We describe our experience with the use of linezolid as part of a multidrug regimen in the treatment of 4 patients who had persistent positive cultures, despite prolonged(More)
Raised serum levels of interleukin 6 (IL-6) have been described in cancer patients. This cytokine mediates the acute phase response and has been also involved in the pathogenesis of cancer cachexia. The objectives of the present study were: (1) to determine the relationships of IL-6 and other cytokines with neoplasia extension, acute phase response and(More)
We characterized 353 isolates responsible for pediatric invasive pneumococcal infections (IPD) in Portugal between 2006 and 2008. Serotypes included in the seven-valent conjugate vaccine (PCV7) accounted for 17% of IPD. Serotypes 1, 7F and 19A were the most frequent causes of IPD and the later consolidated as the most frequent serotype among erythromycin(More)

Abnormalities of the tumour suppressor gene p53 have been shown in approximately 60% of advanced gastric adenocarcinomas and it has been suggested that the immunohistochemical finding of increased p53 expression is a prognostic marker in gastric cancer. No studies of early (T1) tumours have been reported. Over expression of p53 protein in 95 early gastric(More)
Hyperimmunoglobulinemia D and periodic fever syndrome (HIDS; MIM# 260920) is a rare recessively-inherited autoinflammatory condition caused by mutations in the MVK gene, which encodes for mevalonate kinase, an essential enzyme in the isoprenoid pathway. HIDS is clinically characterized by recurrent episodes of fever and inflammation. Here we report on the(More)
Immunohistochemical staining was carried out on a spectrum of normal, hyperplastic and malignant endometrial curettings, for proliferating cell nuclear antigen--PCNA (using the monoclonal antibody PC10) and for abnormally stabilized p53 (using the polyclonal antibody CM-1). The mean proportion of glandular epithelial cells showing PCNA immunoreactivity was(More)
Human adenoviruses (AdVs) typically cause mild illnesses in otherwise healthy hosts. We investigated a pediatric outbreak of acute respiratory infection with fatal outcomes that occurred in Lisbon, Portugal, in 2004. Biological specimens were collected from 83 children attending two nurseries, a kinesiotherapy clinic, and the household of a nanny.(More)
The DNA content of 48 gastric carcinomas from archival material was analysed by static and flow cytometry. By image analysis 81.3% of the tumours were aneuploid and ploidy was related to stage (P = 0.024) and lymph node metastasis. A trend for better survival (> 12 months) was observed in patients with diploid tumours (P = 0.058). The mean 5c exceeding rate(More)
We report the case of a boy with an encephalopathy associated with extrapyramidal and psychiatric symptoms and anti-N-methyl-D-aspartate receptor antibodies. He had positive serum antithyroid antibodies, IgM antibodies against Mycoplasma pneumoniae and human herpesvirus 7 polymerase chain reaction in the cerebrospinal fluid. He was successfully treated with(More)
