The volumes of the whole temporal lobe, the superior temporal gyrus and the corpus callosum were measured on magnetic resonance images from 13 patients with schizotypal personality disorder (SPD), 27 patients with schizophrenia, and 31 age- and sex-matched controls. Temporal lobe structures were traced on consecutive 1.2mm thick SPGR images. Both patient(More)
Pseudomonas testosteroni has been largely overlooked as a potential pathogen in humans. Ten cases of infection due to P. testosteroni were identified at a single metropolitan hospital in Texas during a three-year period. The organism was most often found in association with anatomic abnormalities of the gastrointestinal tract (six of 10 cases); perforation(More)
Children under the age of 5 years experience a disproportionately high rate of bacterial enteric infections. Research has shown a relationship between inadequate child-care center sanitation and illnesses in children. This cross-sectional study assessed the sanitation levels of foodservice surfaces in a sample of 36 Texas child-care centers via recovery and(More)
To investigate the psychometric properties of the German version of the CERAD-NP, neuropsychological deficits were compared between 49 patients with mild cognitive impairment (MCI), 80 patients with Alzheimer's disease (AD), 36 with major depression (MD), and 26 elderly controls. All participants were outpatients of the memory clinic of the Section of(More)

A high-performance liquid chromatography method that utilized fluorescence detection (HPLC-FL) of mycolic acid 6,7-dimethoxycoumarin esters was developed to identify Mycobacterium tuberculosis (MTB) and M. avium complex (MAC) directly from fluorochrome stain smear-positive sputum specimens and young BACTEC 12B cultures. HPLC-FL chromatograms from a training(More)
In April 1994, the largest outbreak of botulism in the United States since 1978 occurred in El Paso, Texas. Thirty persons were affected; 4 required mechanical ventilation. All ate food from a Greek restaurant. The attack rate among persons who ate a potato-based dip was 86% (19/22) compared with 6% (11/176) among persons who did not eat the dip (relative(More)
Foodborne botulism is caused by potent neurotoxins of Clostridium botulinum. We investigated a large outbreak of foodborne botulism among church supper attendees in Texas. We conducted a cohort study of attendees and investigated the salvage store that sold the implicated foods. We identified 15 cases of botulism (40%) among 38 church supper attendees. Nine(More)
The number of Salmonella agona isolates reported annually in Texas from 1992 through 1994 ranged from 14 to 21. An increase in incidence of S. agona infections was noted in the fall of 1995. Pulsed-field gel electrophoresis (PFGE) analysis identified prospectively two possible cryptic outbreaks caused by an indistinguishable strain which was isolated from(More)
BACKGROUND This study compares 4 classifications in patients with progressive refractory Graves orbitopathy (GO) and examines their prognostic value in long-term follow-up. PATIENTS AND METHODS From 1984 to 1994, 60 consecutive patients (49 female, 11 male) received 20 Gy (10 x 2 Gy) radiotherapy with 6 MV Linac photons. Ocular symptoms and functional(More)
