Neuro-Behçet's disease with chorea after remission of intestinal Behçet's disease.

Neuro-Behçet's disease shows various neuropsychiatric symptoms, but chorea has rarely been reported. We report a case of neuro-Behçet's disease in a 67-year-old woman with depression and chorea that occurred 22 years after the onset of intestinal Behçet's disease. Brain magnetic resonance imaging (MRI) using a fluid-attenuated inversion-recovery (FLAIR) sequence demonstrated lesions more clearly than did T2-weighted MRI. Some of the lesions appeared as small ring-like foci, i.e. low-intensity spots rimmed with remarkable hyperintense signals, in the periventricular white matter and basal ganglia. A review of the literature revealed that the onset of chorea in cases of Behçet's disease varied from the time of onset of Behçet's disease to 31 years after onset of the disease. Psychiatric manifestations have often been associated with neuro-Behçet's disease. In the present patient, treatment with prednisolone resolved the chorea, suggesting that the chorea was caused by an autoimmune mechanism. It seems likely that the long-term development of vasculitis in patients with Behçet's disease results in the formation of these particular brain lesions on FLAIR MR images. Chorea should be taken into consideration as one of the manifestations of Behçet's disease, even many years after remission of the disease.

Estimated number of cases of foodborne infectious disease in New Zealand.

AIMS: To estimate the annual number of cases of infectious intestinal disease caused by foodborne pathogens in New Zealand and estimate the impact of these diseases in terms of days lost to illness. METHODS: Incidence of foodborne diseases were derived from data from infectious disease surveillance and hospital sources, and estimates of unreported illnesses using published population based studies. RESULTS: The estimated number of cases of foodborne infectious disease is approximately 119 000 per year, including 19 000 general practitioner visits, 400 hospital admissions, 22 cases of long term illness and two deaths. It is estimated that the number of cases of potentially foodborne infectious disease is approximately 199 000. Total number of cases of all infectious intestinal disease could be as high as 823 000. Days of lost production and leisure time activities lost to foodborne infectious disease are estimated as approximately 497 000. CONCLUSION: Foodborne infectious diseases represent a major public health burden in terms of the number of cases and days lost to illness.

In vitro and in vivo activities of nitazoxanide against Clostridium difficile.

We have used the hamster model of antibiotic-induced Clostridium difficile intestinal disease to evaluate nitazoxanide (NTZ), a nitrothiazole benzamide antimicrobial agent. The following in vitro and in vivo activities of NTZ in the adult hamster were examined and compared to those of metronidazole and vancomycin: (i) MICs and minimum bactericidal concentrations (MBCs) against C. difficile, (ii) toxicity, (iii) ability to prevent C. difficile-associated ileocecitis, and (iv) propensity to induce C. difficile-associated ileocecitis. The MICs and MBCs of NTZ against 15 toxigenic strains of C. difficile were comparable to those of vancomycin or metronidazole. C. difficile-associated ileocecitis was induced with oral clindamycin and toxigenic C. difficile in a group of 60 hamsters. Subgroups of 10 hamsters were given six daily intragastric treatments of NTZ (15, 7.5, and 3.0 mg/100 g of body weight [gbw]), metronidazole (15 mg/100 gbw), vancomycin (5 mg/100 gbw), or saline (1 ml/100 gbw). Animals receiving saline died 3 days post-C. difficile challenge. During the treatment period, NTZ (>/=7.5 mg/100 gbw), like metronidazole and vancomycin, prevented outward manifestations of clindamycin-induced C. difficile intestinal disease. Six of ten hamsters on a scheduled dose of 3.0 mg of NTZ/100 gbw survived for the complete treatment period. Of these surviving animals, all but three died of C. difficile disease by between 3 and 12 days following discontinuation of antibiotic therapy. Another group of hamsters received six similar daily doses of the three antibiotics, followed by an inoculation with toxigenic C. difficile. All of the NTZ-treated animals survived the 15-day postinfection period. Upon necropsy, all hamsters appeared normal: there were no gross signs of toxicity or C. difficile intestinal disease, nor was C. difficile detected in the cultures of the ceca of these animals. By contrast, vancomycin and metronidazole treatment induced fatal C. difficile intestinal disease in 20 and 70% of recipients, respectively.

Prevalence of beta2-toxigenic Clostridium perfringens in horses with intestinal disorders.

The incidence of a new, yet unassigned toxin type of Clostridium perfringens containing the genes for the alpha-toxin and the recently described beta2-toxin in horses with intestinal disorders is reported. The study included 18 horses suffering from typical typhlocolitis, 7 horses with atypical typhlocolitis, 16 horses with other intestinal disorders, and 58 horses without intestinal disease. In total, 20 samples of ingesta of the small and large intestines, five biopsy specimens of the intestinal wall, and 74 fecal samples were analyzed bacteriologically. C. perfringens isolates were typed for the presence of the alpha-, beta-, beta2-, and epsilon-toxin and enterotoxin genes by PCR, including a newly developed PCR for the detection of the beta2-toxin gene cpb2. beta2-Toxigenic C. perfringens was detected in samples from 13 of 25 (52%) horses with typical or atypical typhlocolitis, with a particularly high incidence in specimens of ingesta and biopsy specimens (75%), whereas only 6 of 16 specimens from horses with other intestinal diseases yielded beta2-toxigenic C. perfringens. No beta2-toxigenic C. perfringens was found in the samples from the 58 control horses, of which only one fecal sample contained C. perfringens type A. Among the samples from the 15 horses with fatal cases of typical and atypical typhlocolitis 9 (60%) were positive for beta2-toxigenic C. perfringens, whereas samples from only 4 of the 10 (40%) animals with nonfatal cases of infection were positive. We found an interesting correlation between the antibiotic-treated horses which were positive for beta2-toxigenic C. perfringens and lethal progression of the disease. No C. perfringens strains isolated in this study contained genes for the beta- and epsilon-toxins and enterotoxin. The high incidence of beta2-toxigenic C. perfringens in samples of ingesta, biopsy specimens of the intestinal wall, and feces from horses suffering or dying from typhlocolitis together with the absence of this organism in healthy horses provides strong evidence that beta2-toxigenic C. perfringens play an important role in the pathogenesis of typhlocolitis.

[Differential diagnosis of Crohn disease: segmental intestinal metastasis of breast and stomach cancer].

Metastatic malignancies are able to imitate the radiological or intraoperative findings of Crohn's disease. Being of great importance in individual cases, the manifestation of intestinal metastases mimicking Crohn's disease is analysed. Since 1960 world literature has reported intestinal metastases simulating Crohn's disease in 19 patients. Primary tumours were breast cancer (13 patients), gastric cancer (5 patients) and unknown primary focus (1 patient), in which even postmortem examination failed to reveal the site of primary cancer. 12 (67%) of 18 specified patients showed metastatic infiltration of the terminal ileum. Long segments of narrowing were found in all patients. Since specific signs such as age, sex, localization or macroscopic appearance to differentiate Crohn's disease from metastatic tumour spread are lacking, a histological examination is necessary to establish the correct diagnosis. The median survival time was approximately one year following the intestinal tumour spread.
