Blood pressure in pediatric years (8-13 years old) in the Oporto region.

The early detection and treatment of primary and secondary hypertension in children may contribute to the improvement of health later in life. During childhood, the occurrence of arterial hypertension should be understood as a risk situation, even if the clinical signs of the disease are not obvious. Comparatively to other populations, only few epidemiological studies exist in Portugal to be used as clinical references.

[Human papillomavirus associated with uterine cervix lesions].

It was studied the prevalence of human papillomavirus (HPV) among 228 women with lesions of uterine cervix attending the Ofir Loiola Institute, in Belem, Para, from March 1992 to May 1996. Histopathological examination was performed with all cervical biopsy samples obtained from these patients. In addition, specimens were analysed by both polimerase chain reaction and dot-blot hybridization to detect HPV DNA.

Polyphasic taxonomy of Nesterenkonia halobia.

A phenotypic study has been carried out on six moderately halophilic gram-positive nonmotile cocci isolated from ponds of a saltern located in Huelva, Spain. These strains were examined for 150 morphological, physiological, biochemical, and nutritional traits and showed phenotypic characteristics similar to those of Nesterenkonia halobia (formerly Micrococcus halobius). The guanine-plus-cytosine (G + C) content of their DNA ranged between 70 and 72 mol%, values quite similar to those described for N.

[Immunoproliferative disease of the small intestine. Report of a case].

We report one case of immunoproliferative small intestinal disease with two rare characteristics. Firstly, the detection of monoclonal IgA-Kappa in serum and in the intestinal infiltrate and secondly, the advanced age of the patient at diagnosis. We checked up on Spanish literature and found an important number of patients that were diagnosed at such an age.
