OBJECTIVETo study the digestive system manifestations in children infected with novel influenza A (H1N1) virus.

METHODSA prospective study of 153 children infected with novel influenza A (H1N1) virus in Shenzhen Children's Hospital from November 2009 to January 2010 was conducted. The clinical features and outcomes of 69 children with digestive system manifestations were analyzed.

RESULTSThe children presenting with digestive system manifestations accounted for 45% (69 cases) in the 153 hospitalized children with novel influenza A (H1N1) infection. Gastrointestinal manifestations were observed in 50 cases (33%) and liver function abnormality in 19 cases (12%). The incidence rate of coma, neurological complications, increase in creative kinase level, ICU admission, and death in the patients with digestive system manifestations were significantly higher than those without digestive system manifestations (P<0.05). In the 69 patients with digestive system manifestations, 5 died from severe complications and 64 recovered fully. Gastrointestinal manifestations disappeared through 1 to 3 days and abnormal liver function recovered through 4 to 7 days.

CONCLUSIONSDigestive system manifestations are common in children infected with novel influenza A (H1N1) virus. Neurological system involvements are more common in the patients with digestive system manifestations than those without.

OBJECTIVETo investigate the etiology and clinical manifestation of hemoptysis in children.

METHODA retrospective analysis was performed for 106 cases of hemoptysis who were admitted to The Second Affiliated Hospital & Yuying Children's Hospital of Wenzhou Medical University from January 2005 to December 2014.The clinical information including laboratory tests and image data were collected and analyzed.

RESULTA total of 106 patients (50 males and 56 females) were identified. The median age was 9.1 years (range 2 months to 18 years). Pneumonia (35, 31.1%) was the most common etiology of hemoptysis, which included bacterial pneumonia (27 cases), mycoplasmal pneumonia(4 cases), chlamydial pneumonia (3 cases), and influenza pneumonia(1 case). Other causes included bronchitis(15, 14.2%), pulmonary tuberculosis (11, 10.4%), bronchiectasis (11, 10.4%), diffuse alveolar hemorrhage (8, 7.5%), idiopathic pulmonary hemosiderosis(6, 5.7%), cardiovascular dysplasia(6, 5.7%), pulmonary contusion (4, 3.8%), foreign body in bronchus (2, 1.9%), allergic bronchopulmonary aspergillosis (2, 1.9%). Eighty-six patients manifested mild hemoptysis; moderate and massive hemoptysis were found in nine and eleven patients, respectively. Pneumonia accounted for 33.7% of mild hemoptysis and 45.5% of massive hemoptysis were due to bronchiectasis; 80.2% were treated with antibiotics and 41.5% were given hemostatic agents; 8.5% received lobectomy. Ninety-six patients (90.6%) were cured and parents gave up treatment in 4 cases (3.8%). Six patients (5.7%) suffered from recurrent hemoptysis.

CONCLUSIONHemoptysis mainly occurred in children who were older than 6 years, the most common cause of hemoptysis was respiratory tract infection. In most cases, the amount of hemoptysis was small and the overall prognosis was good.

Novel influenza A (H1N1) virus is the pathogen of recent global outbreaks of febrile respiratory infection. We herein report the imaging findings of pulmonary complication in two patients with novel influenza A (H1N1) infection. The first patient without secondary infection showed the ill-defined ground-glass opacity nodules and patch areas of ground-glass opacities. The second patient with secondary pneumococcal pneumonia showed areas of lobar consolidation in the right middle lobe and left lower lobe and ground-glass opacities.

Neurologic complications of children with influenza A H1N1 2009 pandemic, diagnosed in two consecutive influenza seasons were retrospectively reviewed to seek better outcomes in future outbreaks. Patient demographics, clinical manifestations and neurologic outcomes were reviewed. A total of 1,389 children were diagnosed with influenza A H1N1 by real-time reverse transcriptase-polymerase chain reaction. Of these, 23 (1.7%) patients had neurologic involvement. Their mean age was 5.9 +/- 3.6 yr (range, 6 months to 11 yr) and 16 (69.9%) were boys. None of the 23 patients had been vaccinated for influenza A H1N1 and seasonal influenzas. Twenty-two of the 23 patients presented with seizures. Clinical features included febrile convulsion (n = 19), afebrile convulsion (n = 1), aseptic meningitis (n = 1), encephalopathy (n = 1), and acute necrotizing encephalopathy (n = 1). They all were treated with Oseltamivir twice daily for 5 days immediately after nasal and throat swab testing. Twenty-one of the subjects recovered fully, but the youngest two infants experienced severe neurological sequelae. The results indicate that neurologic complications associated with influenza A H1N1 2009 pandemic were mostly mild, but rarely were serious. Prompt intervention leads to a better outcome and vaccination may prevent the disease, thus staving off serious neurological complications following influenza, especially in young infants.

BACKGROUNDNovel influenza A viruses of avian-origin may be the precursors of pandemic strains. This descriptive study aims to introduce a novel avian-origin influenza A (H10N8) virus which can infect humans and cause severe diseases.

METHODSCollecting clinical data of three cases of human infection with a novel reassortment avian influenza A (H10N8) virus in Nanchang, Jiangxi Province, China.

RESULTSThree cases of human infection with a new reassortment avian influenza A(H10N8) virus were described, of which two were fatal cases, and one was severe case. These cases presented with severe pneumonia that progressed to acute respiratory distress syndrome (ARDS) and intractable respiratory failure.

CONCLUSIONThis novel reassortment avian influenza A (H10N8) virus in China resulted in fatal human infections, and should be added to concerns in clinical practice.
