This report reviews the manifestations in fifteen children of proved adenoviral pneumonia. Patients' ages ranged from 43 days to 4 years and 1 month. Twelve cases were younger than 2 years old. Adenoviral infections were proved by positive viral cultures or a four-fold increase of the complement fixation titer. Prolonged fever and cough were found in all cases. In 13 patients, respiratory distress occurred; 5 needed mechanical ventilation. Injected throats, conjunctivae and ear drums were common. Other clinical pictures included abdominal discomfort, hepatomegaly, skin rash, convulsion and bleeding tendency. Abnormal laboratory findings were mild anemia, leukopenia, thrombocytopenia, elevated erythrocyte sedimentation rate and C-reactive protein, impaired liver function test, and prolonged prothrombin time and partial thromboplastin time. Anemia (11 cases), leukopenia (7 cases) and elevated transaminases levels (7 cases) were more common than previously reported. All patients had para-hilar peribronchial infiltrates in chest roentgenography. Segmental atelectasis and compensated hyper-expansion were found frequently. Pleural effusion were noted in six of our cases. Air leak syndrome occurred in three patients who had received mechanical ventilation. Three of the 15 patients expired: one had a preceding measles infection, all had disseminated intravascular coagulopathy. For patients with antibiotic-resistant pneumonia, adenoviral studies should be done. Extrapulmonary manifestations, and some abnormal laboratory findings, i.e., mild anemia, leukopenia, impaired liver function are clues to adenoviral infections, while bleeding tendency can be regarded as a poor prognostic sign for children with adenoviral pneumonia.

Twenty-three episodes of anticoagulant rodenticide toxicity were found in 21 dogs during a retrospective study conducted at The Ohio State University Veterinary Teaching Hospital. Dyspnea (57%), lethargy (48%), coughing/hemoptysis (30%), and pallor (26%) were the most common presenting complaints. Prolonged activated clotting time (ACT), prolonged one-stage prothrombin time (OSPT), and prolonged activated partial thromboplastin time (APTT) were present in all dogs that had not received any prior therapy. Anemia (83%), thrombocytopenia (61%), hypoproteinemia (57%), positive fibrin degradation products (FDPs) (55%, six of 11 tested), and hyperfibrinogenemia (43%, six of 14 tested) were common hematological findings. Treatment included therapy with vitamin K1, blood products, and supportive care. The survival rate was 83%.

Severe acute respiratory syndrome (SARS) is a highly infectious disease with a significant morbidity and case fatality. The major clinical features include persistent fever, chills/rigor, myalgia, malaise, dry cough, headache and dyspnoea. Less common symptoms include sputum production, sore throat, coryza, dizziness, nausea, vomiting and diarrhoea. Older subjects may present with decrease in general well-being, poor feeding, fall/fracture and delirium, without the typical febrile response. Common laboratory features include lymphopenia with depletion of CD4 and CD8 lymphocytes, thrombocytopenia, prolonged activated partial thromboplastin time, elevated D-Dimer, elevated alanine transminases, lactate dehydrogenase and creatinine kinase. The constellation of compatible clinical and laboratory findings, together with the rather characteristic radiological features especially on HRCT and the lack of clinical response to broad-spectrum antibiotics, should quickly arouse suspicion of SARS. The positivity rates of urine, nasophargyngeal aspirate and stool specimen have been reported to be 42%, 68% and 97%, respectively, on day 14 of illness, whereas serology for confirmation may take 28 days to reach a detection rate above 90%. Recently, quantitative measurement of blood SARS CoV RNA with real-time RT-PCR technique has been developed with a detection rate of 80% as early as day 1 of hospital admission but the detection rates drop to 75% and 42% on day 7 and day 14, respectively.

Angiostrongylosis was diagnosed in 23 dogs presenting to the Queen Mother Hospital for Animals between June 1999 and August 2002. The animals' clinical records were reviewed retrospectively and certain risk factors were compared with a control population of 3407 dogs. Twenty-two of the 23 dogs were from south-east England and dogs from Surrey (n=8) were significantly overrepresented. There were also significantly more Cavalier King Charles spaniels (n=5) and Staffordshire bull terriers (n=5) among the affected dogs than in the control group. The median age of affected dogs was 10 months (range five to 90 months). The most common presenting signs were cough (65 per cent), dyspnoea (43 per cent), haemorrhagic diathesis (35 per cent) and collapse (26 per cent). Four dogs were thrombocytopenic and eight had significant prolongations in prothrombin time and/or activated partial thromboplastin time. Thoracic radiographs were abnormal in 18 of 19 dogs. A variety of changes were observed, the most typical being a patchy alveolar-interstitial pattern affecting the dorsocaudal lung fields. Angiostrongylus vasorum larvae were found in seven of 10 bronchoalveolar lavage specimens and 19 of 19 faecal samples. Three dogs died shortly after admission to the hospital. The remainder were successfully treated with fenbendazole at a dose of 50 mg/kg for five to 21 days. A vasorum should now be considered endemic to south-east England.

Children are susceptible to infection by SARS-associated coronavirus (SARS-CoV) but the clinical picture of SARS is milder than in adults. Teenagers resemble adults in presentation and disease progression and may develop severe illness requiring intensive care and assisted ventilation. Fever, malaise, cough, coryza, chills or rigor, sputum production, headache, myalgia, leucopaenia, lymphopaenia, thrombocytopaenia, mildly prolonged activated partial thromboplastin times and elevated lactate dehydrogenase levels are common presenting features. Radiographic findings are non-specific but high-resolution computed tomography of the thorax in clinically suspected cases may be an early diagnostic aid when initial chest radiographs appear normal. The improved reverse transcription-polymerase chain reaction (RT-PCR) assays are critical in the early diagnosis of SARS, with sensitivity approaching 80% in the first 3 days of illness when performed on nasopharyngeal aspirates, the preferred specimens. Absence of seroconversion to SARS-CoV beyond 28 days from disease onset generally excludes the diagnosis. The best treatment strategy for SARS among children remains to be determined. No case fatality has been reported in children and the short- to medium-term outcome appears to be good. The importance of continued monitoring for any long-term complications due to the disease or its empiric treatment, cannot be overemphasised.

The presence of antiphospholipid antibodies is associated with arterial and venous thrombosis. A young female with initial presentation of dyspnea and cough that lasted for days is reported. A computed tomographic scan of her chest and echocardiography showed features of thrombus formation over the right atrium, complicated with pulmonary thromboembolism. Antiphospholipid syndrome was diagnosed according to elevated activated partial thromboplastin time, high serum titers of anticardiolipin antibody, and the presence of intracardiac thrombus with pulmonary embolism. This thrombus was subsequently removed successfully with surgical intervention, and the patient's recovery was uneventful.

Rectus sheath hematoma (RSH) is an uncommon condition characterized by abdominal pain and an abdominal wall mass. We reviewed the clinical features, treatment, and outcomes of 126 patients treated for RSH at Mayo Clinic from January 1, 1992, to December 31, 2002. Most patients (64%) were women and the mean +/- SD age was 67.9 +/- 16.5 years. Most patients (69%) were on some form of anticoagulation therapy. The mean international normalized ratio was 2.6 +/- 2.4, and mean activated partial thromboplastin time was 64.2 +/- 42.7 seconds. No patients were pregnant or had a peritoneal dialysis catheter at the time of diagnosis. Approximately half of the patients (48%) had nonsurgical abdominal trauma around the time of diagnosis, with 37 patients (29%) having a cough. The most common presenting signs and symptoms were abdominal pain (84%) and an abdominal wall mass (63%). CT of the abdomen and pelvis was the most commonly used method to establish the diagnosis (83%). Most patients (86%) were successfully treated with symptom management and blood transfusion. Ten patients (7.9%) underwent surgery or endovascular embolization of bleeding vessels, and 2 patients (1.6%) died as a result of RSH bleeding. Although RSH is rarely fatal, the clinician should be aware of important risk factors that lead to RSH including female sex, older age, anticoagulation therapy, and cough or other abdominal trauma. Rapid diagnosis with directed history, physical examination, and CT of the abdomen and pelvis may help decrease unnecessary laparotomy and lead to better triage of patients who present with RSH.

To investigate clinical course and outcome of dengue with acute respiratory failure (ARF), and to identify related risk factors for acquiring ARF in dengue, we retrospectively studied 11 dengue patients with ARF. From June to December 2002, a total of 606 adult patients were diagnosed as having dengue. Eleven (1.8%) of 606 dengue patients had complications of ARF. The main causes of ARF were sepsis (n = 6, 54.5%) and upper gastrointestinal (UGI) bleeding (n = 3, 27.3%). The mortality rate was 72.7% (n = 8). Additionally, univariate analysis showed that age, dyspnea, cough, prothrombin time, activated partial thromboplastin time, aspartate aminotransferase, alanine aminotransferase, blood urea nitrogen, creatinine, albumin, renal insufficiency, acute renal failure, acute hepatic failure, UGI bleeding, and combination bacterial infection were significantly predictive variables associated with dengue patients with ARF.

Influenza A/H5N1 infection has become the major emerging infectious disease of global concern again since late 2003. A history of exposure to dead or sick poultry or wild birds occurs in over 60% of cases of human H5N1 infection. The incubation period of avian-to-human transmission is generally between 2 and 5 days and the median duration of symptoms before hospitalization is about 4.5 days. The clinical spectrum has ranged from asymptomatic infection or mild influenza-like illness to severe pneumonia and multi-organ failure. Fever > 38 degrees C, cough and dyspnoea are the major symptoms on presentation, whereas gastrointestinal symptoms such as watery diarrhoea, vomiting and abdominal pain are common early in the course of the disease. In contrast, upper respiratory tract symptoms are less prominent in human H5N1 infection when compared to seasonal influenza. Laboratory features of human H5N1 infection include leucopoenia, especially lymphopenia, elevated amino-transaminases, thrombocytopenia, prolonged prothrombin time and activated partial thromboplastin time, increased D-Dimer, increased serum lactate dehydrogenase and creatinine phospho-kinase, and hypoalbuminemia. A low absolute lymphocyte count on admission is associated with more severe disease and death. Radiographic abnormalities include multi-focal airspace consolidation, interstitial infiltrates, patchy or lobar involvement, with rapid progression to bilateral and diffuse ground-glass opacities consistent with ARDS. However, none of the clinical, laboratory and radiographic features are specific to H5N1 infection. A detailed exposure history needs to be elicited, including any close contact with sick or dead poultry, wild birds, other severely ill persons, travel to an area with A/H5N1 activity or work in laboratory handling samples possibly containing A/H5N1 virus.

: Infection with Angiostrongylus vasorum was diagnosed at necropsy on a dog that died from acute pulmonary haemorrhage, and on recovery of L1 larvae by Baermann examination of faeces from two dogs, one of which had abdominal pain and retroperitoneal haemorrhage, while the other had right-sided heart failure due to cor pulmonale. The presenting signs included syncope (one dog), exercise intolerance (two dogs), cough (two dogs), abdominal pain (one dog) and depression (one dog). One-stage prothrombin time and activated partial thromboplastin time were prolonged in two dogs, buccal mucosal bleeding time was prolonged in one dog and globulin was elevated in all three dogs. Two dogs were treated with fenbendazole and recovered.
