Primary hyperaldosteronism is described in a 27-year-old Brazilian woman from an endemic area of schistosomiasis. She presented with hypokalaemia, cramps and polyuria, refractory hypertension, plasma aldosterone of 40.7 ng/dL and aldosterone/renin activity ratio higher than 100, due to an associated long-standing unsuspected aldosteronoma. Computed tomography showed a well-defined ovoid right a...

ABSTRACT Gravitationally bound companions to stars enable determinations of their masses, and offer clues formation, evolution, dynamical histories. So motivated, we have carried out a speckle imaging survey eight the nearest brightest Wolf–Rayet (WR) directly measure frequency resolvable companions, search for much fainter than hitherto possible. We found one new, close companion each WR 113, ...

(This can be shown using a basis argument, which would amount to what most of you wrote anyway.) Thus, given S ∈ L(V ) such that imS ⊆ imT , we can define R = (T |W )−1S, from which it follows TR = S. Conversely, if S = TR, then since linear operators preserve inclusion and R(V ) ⊆ V , we have S(V ) = (TR)(V ) ⊆ T (V ); that is, imS ⊆ imT . 2. Let T be a linear operator on V with distinct eigen...

Objective: The aim of this study was to identify factors related to the prevalence of caries in 12-year-old schoolchildren. Methods: A cross-sectional study was carried out using a representative sample (n = 1217) of the population of 12-yearold schoolchildren in Galiza (northwest Spain). Independent variables were measured through a questionnaire, and dependent variables were determined throug...

BACKGROUND Approximately 15% of nosocomial infections in the ICU result from spread of bacteria on caregivers' hands. The routine chest radiograph provides an unexamined opportunity for bacterial spread: close contact with each patient and sequential examination of ICU patients. This study examined infection control procedures performed during routine chest radiographs, assessed whether resista...
