Fifty-five dogs received packed red blood cell (PRBC) transfusions for gastrointestinal (GI) hemorrhage during a 26-month period (1999 to 2001), accounting for 11.7% of the PRBC transfusions in that time. Thirty-nine (61%) dogs had an intestinal pathology (primary or secondary) as the cause of GI hemorrhage, including intestinal masses, gastroenteritis, hepatic disease, and renal disease. Nonsteroidal and steroidal anti-inflammatory drug use was found frequently in dogs with GI hemorrhage. Sixteen (39%) dogs were identified as having immune-mediated thrombocytopenia (IMT) and associated GI hemorrhage. Dogs with IMT received more transfusions of PRBC than nonIMT dogs (P<0.03) and received a significantly larger total volume of PRBC (P<0.01) during hospitalization.

A 62-year-old male died of colchicine poisoning after accidental ingestion of Colchicum autumnale (meadow saffron). He ate a salad of plant with green leaves regarded as wild garlic (Allium ursinum). A few hours later he developed symptoms of gastroenteritis and was admitted to hospital. In spite of gastric lavage, activated charcoal and supportive measures, multi-organ system failure developed over the next two days. Laboratory analysis showed highly elevated blood concentrations of hepatic enzymes, creatine kinase, lactate dehydrogenase and blood urea nitrogen, as well as leukocytopenia and thrombocytopenia. Mechanical ventilation, dopamine, noradrenaline, crystalloid solutions and fresh frozen plasma were applied but despite treatment the patient died five days after the ingestion. Post-mortem examination revealed hepatic centrilobular necrosis, nephrotoxic acute tubular necrosis, petechial bleeding in fatty tissue, blunt and shortened intestinal villi and cerebral toxic edema. Botanical identification of incriminated plant gave Colchicum autumnale which confirmed colchicine poisoning. Although the accidental ingestion of Colchicum autumnale is rare and to our knowledge only five such cases have been described in detail, this is the second fatal case in Croatia described in the last 3 years.

Hemolytic uremic syndrome is caused primarily by Shiga toxin-producing Escherichia coli O157:H7. The most common cause of acute renal failure in children, hemolytic uremic syndrome also can occur in adults. Characteristic features of the syndrome are microangiopathic anemia, thrombotic thrombocytopenia, and renal failure. Although the presentation of this syndrome is diverse, the classic prodromal illness is bloody diarrhea following ingestion of hamburger meat contaminated with E. coli O157:H7, the most common mode of infection in the United States. Children with hemolytic uremic syndrome generally present with gastroenteritis complaints (e.g., abdominal pain or tenderness, nausea or vomiting, fever, anemia); affected adults may be asymptomatic. Complications from hemolytic uremic syndrome can include intussusception, chronic renal failure, and seizures in severe cases. Because an incubation period of approximately one week occurs between the start of diarrhea and the onset of hemolytic uremic syndrome, physicians should maintain a high index of suspicion; early laboratory testing is important to diagnose and manage this syndrome. Obtaining a complete blood count and stool culture and performing Shiga toxin testing are the first of a series of tests that may help diagnose hemolytic uremic syndrome.

The aim of this study was to determine the pathogenicity of an Indian bovine viral diarrhea virus (BVDV) 1b isolate in 7-9-months-old male calves. Infected (four) and control (two) calves were bled at three days interval for hematological, virological and serological studies until day 27. All infected calves developed respiratory illness, biphasic pyrexia, mild diarrhea, leucopenia and mild thrombocytopenia. Viraemia was demonstrated between 3 and 15dpi and the infected calves seroconverted by 15dpi. Prominent kidney lesions were endothelial cell swelling, proliferation of mesangial cells and podocytes leading to glomerular space obliteration. Degeneration and desquamation of cells lining seminiferous tubules were observed in two infected calves. Consolidation of lungs with interstitial pneumonia, mild gastroenteritis and systemic spread were also evident. It was concluded that Indian BVDV isolate induced moderate clinical disease in calves and glomerulonephritis resulting from acute BVDV infection was observed for the first time.

Gastroenteritis due to Escherichia coli O157:H7 occurs in young children and is associated with consumption of under cooked beef. Approximately 5-10% of patients will develop hemolytic uremic syndrome (HUS): renal failure, microangiopathic hemolytic anemia, and thrombocytopenia. A 6-year-old boy was admitted with abdominal pain, guaiac positive stool, decreased urine output and elevated creatinine levels. Hemodialysis was initiated upon rapid progression to anuria. On hospital day # 5 he developed acute abdominal pain, which was different from his initial assessment. Exam revealed focal tenderness in the right lower quadrant with localized guarding and rebound. Ultrasound demonstrated a dilated, fluid filled tubular structure in the RLQ concerning for appendicitis. Based on these findings the patient was taken to the operating room for a laparoscopic appendectomy. The patient had undergone dialysis the previous day and was preoperatively treated with DDAVP to minimize the risk of bleeding. The procedure occurred without complication and final pathology confirmed acute appendicitis. This case highlights the unique clinical scenario in which patients with HUS require operative intervention. Surgical procedures can be performed on these patients, however, all precautions should be taken to minimize the risk of bleeding, including the use of preoperative DDAVP.

An unusual case of malaria presented with gastroenteritis and bloody diarrhoea in a 46-year-old male. The patient was a non-Saudi resident of Makkah, Saudi Arabia. Fever was not the presenting complaint, and the patient had not experienced any chills or sweating. He gave history of recent travel to Pakistan. Initial laboratory investigations showed anemia, thrombocytopenia, normal liver function, and negative blood film for malaria. His widal, Brucella, and dengue serology was negative. Endoscopic examination showed gastroenteritis. On the fifth day of admission, a sexual form of Plasmodium falciparum on peripheral smear was reported by chance. Malaria was misdiagnosed because of initial negative blood film which may have been due to false microscopy or a long period between exposures and positive blood film. We concluded that a repeat blood film for malaria at 12- to 24-hour intervals for 48 to 72 hours is cost effective when a patient has recently travelled to an endemic area.

Temozolomide (TMZ) is an oral alkylating agent with proven antitumoral activity in preclinical and clinical studies in adults with high-grade glioma (HGG). However, only limited efficacy has been reported in children with HGG using the 5-day schedule. This study investigated the safety of administering TMZ to children and adolescents with brain tumors over an extended period. Extended schedules have been proven to overcome chemoresistance without any major toxicity. The toxicity of TMZ, administered at 70 mg/m(2)/day orally for 21 consecutive days every 28 days, was assessed in children with brain tumors. A total of 156 courses of TMZ were given to 17 patients (median age 12.5 years, range 1-17 years), who were recruited into the study. Eleven patients had progressive or relapsing disease, and six patients were newly diagnosed. In this cohort no cases of toxic death or nonhematological toxicity were reported. In comparison with the 5-day schedule, thrombocytopenia and neutropenia were noted to be less frequent. Grades 3 and 4 lymphopenia occurred in 10.8 and 22.4% of courses, respectively; among the lymphopenic patients there was one case of disseminated zoster (meningoencephalitis and cutaneous involvement), one case of rotavirus gastroenteritis, and two cases of herpetic stomatitis reported. The objective response rate was 11.8%. Overall, 82.3% of patients showed stable disease. The prolonged TMZ schedule appeared to be well tolerated, with few cases of neutropenia or thrombocytopenia recorded. Nevertheless, prolonged exposure to TMZ was associated with lymphopenia and may lead to a higher rate of viral infections.

The aim of this paper is to report the epidemiological, clinical and diagnosis findings of pneumonia and pulmonary hemorrhage observed in patients with leptospirosis in the period January 2007 to October 2009. A 64% (20/31) of patients diagnosed with leptospirosis presented pneumonia. Fifteen of them (75%) had severe pneumonia, of which seven (35%) were pulmonary hemorrhage. In ten patients (32%) reason for consultation and clinical early stage was a secretory gastroenteritis with fever and abdominal pain. Jaundice was only expressed in eleven patients (35%). The technique of chain reaction (PCR) was useful for diagnosis in samples obtained post mortem. A strain classified in serogroup canicola was isolated from blood culture. Pneumonia was classified into three types: non-severe pneumonia course with little overall impact; severe pneumonia associated with systemic clinical forms with jaundice, renal failure, thrombocytopenia, and pulmonary hemorrhage, and of serious course, not associated with jaundice, kidney failure or thrombocytopenia. Antibiotic treatment started in the early stages of disease (average 3.2 days) had no influence on the development of severe pneumonia. It is puggested to consider three clinical forms of leptospirosis: anicteric, icteric (with its evolutionary variants) and pulmonary hemorrhage.

This review is focused on childhood specific aspects of malaria, especially in resource-poor settings. We summarise the actual knowledge in the field of epidemiology, clinical presentation, diagnosis, management and prevention.These aspects are important as malaria is responsible for almost a quarter of all child death in sub-Saharan Africa. Malaria control is thus one key intervention to reduce childhood mortality, especially as malaria is also an important risk factor for other severe infections, namely bacteraemia.In children symptoms are more varied and often mimic other common childhood illness, particularly gastroenteritis, meningitis/encephalitis, or pneumonia. Fever is the key symptom, but the characteristic regular tertian and quartan patterns are rarely observed. There are no pathognomonic features for severe malaria in this age group. The well known clinical (fever, impaired consciousness, seizures, vomiting, respiratory distress) and laboratory (severe anaemia, thrombocytopenia, hypoglycaemia, metabolic acidosis, and hyperlactataemia) features of severe falciparum malaria in children, are equally typical for severe sepsis.Appropriate therapy (considering species, resistance patterns and individual patient factors) - possibly a drug combination of an artemisinin derivative with a long-acting antimalarial drug - reduces treatment duration to only three days and should be urgently started.While waiting for the results of ongoing vaccine trials, all effort should be made to better implement other malaria-control measures like the use of treated bed-nets, repellents and new chemoprophylaxis regimens.

We characterized the complete genome of a novel dog circovirus (DogCV) from the liver of a dog with severe hemorrhagic gastroenteritis, vasculitis, and granulomatous lymphadenitis. DogCV was detected by PCR in fecal samples from 19/168 (11.3%) dogs with diarrhea and 14/204 (6.9%) healthy dogs and in blood from 19/409 (3.3%) of dogs with thrombocytopenia and neutropenia, fever of unknown origin, or past tick bite. Co-infection with other canine pathogens was detected for 13/19 (68%) DogCV-positive dogs with diarrhea. DogCV capsid proteins from different dogs varied by up to 8%. In situ hybridization and transmission electron microscopy detected DogCV in the lymph nodes and spleens of 4 dogs with vascular compromise and histiocytic inflammation. The detection of a circovirus in tissues of dogs expands the known tropism of these viruses to a second mammalian host. Our results indicate that circovirus, alone or in co-infection with other pathogens, might contribute to illness and death in dogs.
