Infection with an atypical (lactose-negative) E. coli was associated with increased mortality rates in a colony of triple immune deficient N:NIH(S) III mice. Affected mice were lethargic and exhibited perianal fecal staining. Slight-to-moderate thickening of the wall of the cecum and colon was found on necropsy examination. Microscopic examination revealed segmental hyperplasia of the cecal and colonic mucosa with clusters of gram negative bacteria on the surface and within the cytoplasm of mucosal epithelial cells. Scattered foci of epithelial invasion and hyperplasia were observed in the colons of C57B1/6N-nunu mice after per os inoculation with the atypical E. coli. Immunocompetant mice housed in the same room as the N:NIH(S) III's remained healthy and exhibited no gross or microscopic lesions in spite of infection.

1 The effects of triprolidine and cyclizine on the histamine skin response, performance tests and subjective effects were examined in a controlled, double-blind study in eight healthy volunteers. 2 Triprolidine was considerably more potent that cyclizine in inhibiting the skin response to histamine. Significant inhibition of flare size occurred at 1, 2 an 4 h after triprolidine 2.5 mg. A smaller but significant reduction occurred at 2 and 4 h after cyclizine 100 mg but not after the 50 mg dose. 3 Cyclizine 100 mg produced a significant increase in reaction time at 4.5 h compared with lactose. Smaller though non significant increases followed triprolidine and cyclizine 50 mg. 4 Subjective effects were seen only after cyclizine 100 mg when subjects were significantly more drowsy, feeble, muzzy, lethargic and dreamy than after lactose dummy. No significant changes followed triprolidine 2.5 mg or cyclizine 50 mg. 5 It was concluded that while cyclizine has antihistamine properties, these are weak compared with triprolidine, and are not seen with doses sufficiently low to avoid central nervous system impairment.

A 3-mo-old, 12-kg, intact, miniature pig presented with severe neurologic signs on day 8 after hematopoietic cell transplantation. This pig had received an immunosuppressive regimen before transplantation that included an antiCD3 immunotoxin for T-cell depletion, 100 cGy of total-body irradiation, and cyclosporine for 45 d. The pig began exhibiting erythematous lesions on posttransplantation day 7. He also demonstrated increased conscious proprioceptive deficits and recumbency but normal mentation. Neurologic signs worsened over several days; the pig became lethargic but remained afebrile. Conjunctival swelling developed on posttransplantation day 9, which subsequently spread to the animal's head, ears and hocks by day 10. Analgesics were given for pain, and cyclosporine levels were decreased. Despite the measures taken, neurologic signs progressed. Given the worsening subcutaneous edema and neurologic status, Escherichia coli infection was suspected, and treatment with a third-generation cephalosporin was instituted. The clinical signs resolved within 12 h after the start of antibiotics. 'Shiga-like' toxin from E. coli can cause peracute toxemia and induce ataxia, paralysis, and recumbency. Other common and pathognomonic findings include periocular edema and variable edema in other subcutaneous regions. A fecal sample demonstrated an overgrowth of gram-negative, lactose-fermenting colonies. On the basis of the clinical presentation, exclusion of other potential conditions compatible with edema and neurologic diseases, physical exam findings, microbiology and the resolution of signs after therapy, the pig was diagnosed with edema disease.

Galactosemia is a rare autosomal recessive genetic disorder that causes impaired metabolism of the carbohydrate galactose. This leads to severe liver and kidney insufficiency, central nervous system damage and long-term complications in newborns. We present two clinical cases of classical galactosemia diagnosed at the Lithuanian University of Health Sciences (LUHS) Kaunas Clinics hospital and we compare these cases in terms of clinical symptoms and genetic variation in the GALT gene. The main clinical symptoms were jaundice and hepatomegaly, significant weight loss, and lethargy. The clinical presentation of the disease in Patient 1 was more severe than that in Patient 2 due to liver failure and E. coli-induced sepsis. A novel, likely pathogenic GALT variant NM_000155.4:c.305T>C (p.Leu102Pro) was identified and we believe it could be responsible for a more severe course of the disease, although further study is needed to confirm this. It is very important to suspect and diagnose galactosemia as early in its course as possible, and introduce lactose-free formula into the patient's diet. Wide-scale newborn screening and genetic testing are particularly crucial for the early detection of the disease.
