Late adult onset of Langerhans cell histiocytosis mimicking glioblastoma multiforme.

Langerhans cell histiocytosis (LCH) with multiple organ involvement is a rare disorder in adults. Extrapituitary involvement of the central nervous system (CNS) is uncommon. We report the unusual case of a 55-year-old woman presenting with a left-sided hemiataxia-hemiparesis, left hemisensory loss and short-lasting episodes of an alien left hand due to lesions of the internal capsule and the right thalamus, extending into the mesencephalon associated with extensive surrounding edema, without pituitary involvement.

Clinical study of the color stability of veneering ceramics for zirconia frameworks.

Purpose: The purpose of this study was to compare 3 veneering ceramics for zirconia frameworks regarding color stability and predictability of the esthetic result.

Materials And Methods: Six patients with 1 maxillary central incisor to be restored were enrolled in the study. The contralateral incisor had to be nonrestored and vital to serve as a reference tooth.

[Traps of tuberculosis among the aged: an astonishing cyst of left foot].

We report the case of a 75 years old man who insidiously developed a unusual presentation of tuberculosis. The story began with a tuberculous arthritis of the foot, later associated with pulmonary, endobronchial, mediastinal and cervical lymphadenitis tuberculosis. Because the microscopic examination was negative for acid-fast bacilli (AFB) in all involved sites, the diagnosis of sarcoidosis was suggested.

Predicting survival of patients with sepsis by use of regression and neural network models.

Objectives: (1) To predict at the time of diagnosis of sepsis the subsequent occurrence of multiple organ failure and patient death; and (2) to compare the prediction accuracies of standard multiple logistic regression (MLR) and neural network (NN) models.

Methods: The data were collected during a 5-year period for all patients (n=173) who met prospectively determined criteria for sepsis and had positive blood culture results while admitted in the surgical intensive care unit at the University Hospital of Geneva, Switzerland. These data formed the basis for a retrospective cohort study described elsewhere.

Bedside prediction of mortality from bacteremic sepsis. A dynamic analysis of ICU patients.

The prognosis in patients with sepsis depends on severity of acute illness, underlying chronic diseases, and complications associated with infection. Adjusting for these factors is essential for evaluation of new therapies. The purpose of the present study was to determine variables readily identifiable at the bedside that predict mortality in intensive care unit (ICU) patients with sepsis and positive blood cultures.
