Happel R - - 1998
Novel species are introduced into a network of interacting replicators either (i) as mutants of members of the network (ii) as unrelated immigrants. We consider the meta-population dynamics of such a system. In the first case the appearance of mutants leads to a slow growth of the replicator network, proportional ...

We hypothesized that psychiatrists with high dual-agency potential (military and health maintenance organization [HMO] psychiatrists) were more likely than non-HMO civilian psychiatrists to engage in dual relationships, report pressures to do so, participate in other general boundary-crossing activities, and report associated counter-therapeutic outcomes (boundary violations). Ninety military and 191 demographically ...

Aneurysmal subarachnoid haemorrhage is associated with a uniquely severe headache of acute onset. Classical cases are readily identified as such, although this is not always the case. Four cases who were admitted to a district general hospital within a 3-month period are presented, because they demonstrate a variety of presentations, ...

The onchocercid nematode Foleyella candezei was collected from an imported Fisher's chameleon, Bradypodion fischeri, during necropsy. This represents a new host record for this helminth, as well as being only the third nematode species to be collected from B. fischeri. The synonymy of F. candezei and Foleyella agamae is reviewed, ...

Adverse drug events (ADEs) are both common and costly. Most hospitals identify ADEs using spontaneous reporting, but this approach lacks sensitivity; chart review identifies more events but is expensive. Computer-based approaches to ADE identification appear promising, but they have not been directly compared with chart review and they are not ...

The first identified covalent flavoprotein, a component of mammalian succinate dehydrogenase, was reported 42 years ago. Since that time, more than 20 covalent flavoenzymes have been described, each possessing one of five modes of FAD or FMN linkage to protein. Despite the early identification of covalent flavoproteins, the mechanisms of ...

Five patients suffering from idiopathic cricopharyngeal dysfunction (without Zenker's diverticulum) were treated surgically. Together with cricopharyngeomyotomy biopsies were taken at the level of the cricopharyngeus. Histological, enzyme hystochemical and electronmicroscopic examinations were performed on all patients. In two cases the histology revealed myogen dystrophy (presence of necrosis, myophagocytosis, abnormal fiber ...

A workshop discussing eight clusters of hypersensitivity pneumonitis in the automotive industry among metalworking fluid-exposed workers concluded that a risk exists for this granulomatous lung disease where water-based fluids are used and unusual microbial contaminants predominate. Strong candidates for microbial etiology are nontuberculous mycobacteria and fungi. Cases of hypersensitivity pneumonitis ...

Generalized essential telangiectasia was well defined more than 30 years ago. There have been no reported cases of associated gastrointestinal (GI) bleeding. Recurrent hemorrhage in the setting of telangiectases, including GI bleeding, is more typically associated with hereditary hemorrhagic telangiectasia. We report a unique case of a woman with generalized ...

Sudden sensorineural hearing loss (SNHL) is a well-recognized phenomenon that is attributed to a variety of etiologies. Sudden SNHL after cardiopulmonary bypass surgery has been well reported and is thought to be due to microemboli. However, a review of the English literature revealed only 15 cases of SNHL after general ...

In summary, we report two cases of mesenteric ischemia following cocaine abuse in young women. In such cases it is always difficult to prove a direct causal relationship between the abuse of cocaine and mesenteric ischemia. Both our patients were relatively young (in their thirties) and did not have any ...

Transiently click-evoked (TEOAE), distortion product (DPOAE) and spontaneous otoacoustic emissions (SOAE) were recorded and changes in these tests were studied during the recovery process in 15 cases of idiopathic sudden deafness (ISD). In all these cases the amplitudes of TEOAEs and DPOAEs increased concurrently with the recovery of the hearing ...

To assess the recognition of non-neoplastic epithelial alterations of the vulva and to compare terminologies used for these lesions by various specialties, we performed a clinical and dermatopathologic review of all of the cases diagnosed as non-neoplastic epithelial alterations of the vulva that were followed by one gynecologist. Forty-five initial ...

Feed samples from 94 cases involving fungal contamination and suspected mycotoxicosis of farm animals in western Canada were examined during 1982-1994 to assess the incidence of mycotoxins. Samples were analyzed for aflatoxins, ochratoxin A, citrinin, sterigmatocystin, and the fungal estrogen zearalenone. Samples infected with Fusarium fungi were additionally assayed for ...

Alopecia areata has never been documented in a newborn. Thus, it is generally assumed that alopecia areata is acquired only postnatally, and it is believed that the presence of an alopecia at birth virtually excludes its diagnosis. In this report we document a case of alopecia areata in a premature ...
