An outbreak of dual infection in dogs with canine adenovirus type 1 (CAV-1) and canine coronavirus (CCV) infection is reported in an animal shelter that comprised approximately 200 adults stray dogs and 30 puppies. Twenty puppies died 7-8 days after the onset of the clinical signs (severe enteritis, leucopoenia, respiratory distress and dehydration). Both CAV-1 and CCV were isolated from tissue or swab samples. Antibodies to CCV and, at high levels, to CAV-1 also were detected in several puppies. The principal histological findings were atrophy of small intestinal villi, lymphoid depletion, hepatitis and bronchopneumonia. The persistence of CCV in the faeces, observed by the polymerase chain reaction assay, was longer than previously reported. Results demonstrated the serious consequences which may occur with dual infections by CAV-1 and CCV in assembled groups of dogs that are housed in poorly managed kennels with inadequate vaccination programmes.

Arsenic poisoning was diagnosed in a 26-year-old man who had been criminally intoxicated over the last two weeks preceding admission by the surreptitious oral administration of probably 10 g of arsenic trioxide (As2O3). The patient developed severe manifestations of toxic hepatitis and pancreatitis, and thereafter neurological disorders, respiratory distress, acute renal failure, and cardiovascular disturbances. In addition to supportive therapy, extrarenal elimination techniques and chelating agents were used. Dimercaprol (BAL) and dimercaptosuccinic acid (DMSA or succimer) were used simultaneously as arsenic chelating agents for two days, and thereafter DMSA was used alone. DMSA was administered by intravenous (20 mg/kg/d for five days, then 10 mg/kg/d for six days) and intraperitoneal route. Intravenous DMSA infusion was well tolerated and resulted in an increase in arsenic blood concentration immediately after the infusion. Continuous venovenous hemofiltration combined with hemodialysis, and peritoneal dialysis were proposed to enhance arsenic elimination. It was calculated that over an 11-day period 14.5 mg arsenic were eliminated by the urine, 26.7 mg by hemodialysis, 17.8 mg by peritoneal dialysis, and 7.8 mg by continuous venovenous hemofiltration. These amounts appeared negligible with regard to the probable ingested dose. The patient died on day 26 from the consequences of multiple organ failure, with subarachnoid hemorrhage and generalized infection caused by Aspergillus fumigatus.

Acute thrombotic thrombocytopenic purpura (TTP) is a life-threatening disorder that has previously been described associated with various types of surgery. An association between total abdominal hysterectomy (TAH) and TTP has never been reported. Thrombotic thrombocytopenic purpura is classically characterized by thrombocytopenia, microangiopathic hemolytic anemia, fever, azotemia and neurological manifestations. Atypical manifestations of TTP include hepatitis, pancreatitis, acute respiratory distress syndrome, non-occlusive mesenteric ischemia and peripheral digital ischemia. This case report describes the occurrence of acute TTP following TAH and bilateral salpingo-oopherectomy, which manifested with typical and atypical features (i.e. hepatitis, pancreatitis). Plasma exchange therapy resulted in the complete resolution of the process.

A 50-year-old man with no medical history was admitted because of progressive respiratory distress, aseptic meningitis, disseminated intravascular coagulation, cholestatic hepatitis, and renal failure. Mycoplasma pneumoniae infection was confirmed serologically. The patient was treated with erythromycin and showed a favorable recovery. Although M. pneumoniae infection is usually a benign, self-limited acute respiratory disease, on rare occasions it can manifest itself with a fulminant course and multi-organ involvement, even in normal healthy individuals.

Mycoplasma pneumoniae (Mp) is an important cause of pneumonia in paediatric age, but also other organs or systems can be affected even without pulmonary involvement. The purpose of this study is to stress the unusual clinical features of Mp infection in children. A review of children affected with Mp infection with peculiar pulmonary and/or extra-pulmonary forms is reported. Diagnosis of Mp infection was always confirmed by serum anti-Mp antibody assay. Two patients with infection of the lower airways showed severe respiratory distress; nine cases with only extra-pulmonary manifestations presented urticaria and arthralgia; three patients had severe neuromuscular impairment, one of these resulting in flaccid tetraparesis; one 2-year-old child had anicteric hepatitis, without any sequelae; one case of a 6-year-old child presented severe haemolytic anaemia, and a 5-year-old child with Schonlein-Henoch purpura. In conclusion, Mp infection, a frequent cause of pneumonia at all paediatric ages, may also give rise to extrapulmonary manifestations. Frequently, muscular-articular or neurological systems, skin or other organs are involved. Clinical suspicion of Mp infection is essential in severe cases and the outcome of all pulmonary and/or extra-pulmonary manifestations depends on early diagnosis and specific therapy.

A TRIAD OF FEATURES: Adult onset Still's disease (ASD) is an uncommon disorder usually associating high spiking fever, evanescent skin rash constituted of small salmon pink macules, and arthritis. NUMEROUS SYSTEMIC MANIFESTATIONS: A sore throat is common and often misleading. More than 60% of the patients develop mobile and indolent lymph nodes, usually in the cervical area. Liver involvement is common and usually limited to a mild or moderate cytolysis. However, several observations of severe hepatitis have been reported justifying strict monitoring of the liver biology in these patients. Amongst the other numerous systemic manifestations that have been reported, pericarditis is common and sometimes responsible for tamponade, the pulmonary involvement may lead to an acute respiratory distress, and the rare neurological manifestations include aseptic meningitis or cranial nerve palsy. FROM A BIOLOGICAL POINT OF VIEW: The sedimentation rate is consistently elevated and there is usually a marked elevation in the polymorphonuclears. The bacteriological survey is negative as are the immunological tests. An increase in the serum level of IL-18 might be both diagnostic and prognostic. It is the increase of the serum level of ferritin and the marked decrease in its glycosylated fraction below 20% that seem to be of more potent diagnostic value.

The present study reports the clinical, virological and pathological findings observed in a natural outbreak of highly pathogenic avian influenza in farmed commercial ducks. The ducks developed clinical signs, including mild respiratory distress, depression, mild diarrhoea, loss of appetite and increasing mortality (up to 12%). At necropsy, multifocal mottled necrosis was commonly found in the pancreas with splenomegaly, hepatomegaly, and swollen kidneys. Microscopically, there was necrotized pancreatitis and hepatitis, and lymphocytic meningoencephalitis and myocarditis. Influenza viral antigen was demonstrated in areas closely associated with histopathological lesion. Avian influenza virus was isolated from the caecal tonsil, faeces, and kidney of the domestic ducks. The isolated virus was identified as a highly pathogenic H5N1, with a haemagglutinin proteolytic cleavage site deduced amino acid sequence of ... QREKRKKR/GLFGAIAG ... In order to determine the pathogenicity of the isolate, eight 6-week-old specific pathogen free chickens were inoculated intravenously with the virus, and all birds died within 24 h after inoculation. This is the first report of an outbreak of highly pathogenic avian influenza with clinical signs in commercial domestic ducks in South Korea.

Human and animal infections by Anaplasmataceae are increasingly recognized as important and potentially fatal arthropod-transmitted diseases. Since the first recognition and implementation of diagnostic methods for human infection by Ehrlichia chaffeensis and Anaplasma phagocytophilum, the incidence of infections has linearly increased. Moreover, diagnostic and epidemiological testing indicates that "ehrlichia" infections are globally distributed and suggests that additional agents of human and veterinary "ehrlichiosis" will be identified. With increasing disease identification has come recognition that the infections can be severe, with approximately one-half of patients requiring hospitalization for complications including respiratory distress, myocarditis, neurological complications, hepatitis, a septic or toxic shock-like disease, opportunistic infections, and death in 0.5 to 3.0%. An understanding of the diseases, pathophysiology, pathogenesis, control, and management will best be developed through fundamental investigations. Advances in comprehension as to the separate contributions of bacteria and host are crucial since most data now suggest that alterations in host neutrophil function and protection from innate and adaptive immunity also contribute to disease manifestations. It is reasonable to operate from the hypothesis that these host cell functional changes ultimately benefit bacterial survival while inadvertently eliciting clinical disease in poorly adapted hosts. A firmer basis for the scientific understanding of Anaplasmataceae biology will allow logical and rational approaches toward infection control, prevention, and treatment.

Adenoviruses (AdV) are opportunistic pathogens that can lead to severe infections and respiratory failure (acute respiratory distress syndrome, ARDS) with high mortality in immunosuppressed patients. Cidofovir (CDV) has been used in adenoviral disease in bone marrow transplant recipients. Two pediatric liver transplant recipients with disseminated adenoviral disease and ARDS were treated with reduction of immunosuppression, CDV, and inhaled nitric oxide (iNO). CDV 1 mg/kg was given three times per week intravenously with intravenous hydration and oral probenecid. Viral suppression and clinical improvement was achieved. AdV hepatitis did not occur, and graft function was preserved, although acute rejection occurred in both patients. Adverse effects were mild and transient not requiring dose modification. Severe hypoxemia was reversed with iNO 10-20 p.p.m. CDV treatment of AdV infections in organ transplant recipients and other immunocompromised patients should be further investigated in prospective studies.

Cytokines are multifunctional proteins that play a critical role in cellular communication and activation. Cytokines have been classified as being proinflammatory (T helper 1, Th1) or anti-inflammatory (T helper 2, Th2) depending on their effects on the immune system. However, cytokines impact a variety of tissues in a complex manner that regulates inflammation, cell death, and cell proliferation and migration as well as healing mechanisms. Ethanol (alcohol) is known to alter cytokine levels in a variety of tissues including plasma, lung, liver, and brain. Studies on human monocyte responses to pathogens reveal ethanol disruption of cytokine production depending upon the pathogen and duration of alcohol consumption, with multiple pathogens and chronic ethanol promoting inflammatory cytokine production. In lung, cytokine production is disrupted by ethanol exacerbating respiratory distress syndrome with greatly increased expression of transforming growth factor beta (TGFbeta). Alcoholic liver disease involves an inflammatory hepatitis and an exaggerated Th1 response with increases in tumor necrosis factor alpha (TNFalpha). Recent studies suggest that the transition from Th1 to Th2 cytokines contribute to hepatic fibrosis and cirrhosis. Cytokines affect the brain and likely contribute to changes in the central nervous system that contribute to long-term changes in behavior and neurodegeneration. Together these studies suggest that ethanol disruption of cytokines and inflammation contribute in multiple ways to a diversity of alcoholic pathologies.
