1/201. cytomegalovirus associated neonatal pneumonia and Wilson-Mikity syndrome: a causal relationship?lung injury caused by intrauterine inflammation has recently been strongly implicated in the pathogenesis of Wilson-Mikity syndrome (WMS). This article supports this theory by suggesting a causative role of intrauterine cytomegalovirus (CMV) infection for the development of WMS. A male premature infant, born at 33 weeks of gestational age, developed chronic lung disease compatible with WMS and diagnostic evaluation was positive for CMV infection. High-resolution computed tomography scan and lung histology revealed typical features of WMS in association with signs of interstitial pneumonia. CMV was found in urine, breastmilk, bronchoalveolar lavage material and lung tissue from open lung biopsy. Follow-up after treatment with ganciclovir and steroids showed resolving lung disease at the age of 6, 10 and 16 months, with lung function signs of mild obstruction. Assuming that a chance coexistence of cytomegalovirus pneumonia and Wilson-Mikity syndrome is rather unlikely, it is possible that intrauterine cytomegalovirus infection caused a pattern of lung injury consistent with Wilson-Mikity syndrome. Further cases of Wilson-Mikity syndrome should be investigated as to a possible role of congenital infection.- - - - - - - - - - ranking = 1keywords = infection (Clic here for more details about this article) |
2/201. chickenpox pneumonia: case report and literature review.The incidence of primary chickenpox infection in young adults appears to be rising in the UK and other developed countries. The infection is more severe in adults than in children and complications, including pneumonia, are more frequent. An illustrative case of severe chickenpox pneumonia in an immunocompetent, non-pregnant adult smoker is presented. The epidemiology and pathology of the disease is discussed and a review of current management in the emergency department and the intensive care unit is presented. Strategies for the prevention of chickenpox pneumonia are also discussed.- - - - - - - - - - ranking = 0.5keywords = infection (Clic here for more details about this article) |
3/201. The first case of H5N1 avian influenza infection in a human with complications of adult respiratory distress syndrome and Reye's syndrome.Avian influenza virus was not known to cause systemic infection in humans before. We report a 3-year-old boy with good past health who developed pneumonia caused by H5N1 avian influenza a virus (A/hong kong/156/97). The virus was isolated from a tracheal aspirate. There were complications of Reye's syndrome, adult respiratory distress syndrome, and multiple organ system failure. He had a history of receiving aspirin. His adult respiratory distress syndrome did not respond to endotracheal surfactant replacement therapy. He died 6 days after admission. Clinicians should be alert to the importance of a new human influenza strain.- - - - - - - - - - ranking = 1.25keywords = infection (Clic here for more details about this article) |
4/201. Massive pulmonary hemorrhage due to cytomegalovirus infection in a Japanese patient with alpha-1-antitrypsin-deficient emphysema.Although alpha(1)-antitrypsin (AAT) deficiency is one of the most common hereditary diseases and a recognized cause of emphysema in Caucasians, variants of this deficiency are extremely rare among Orientals. We present here a Japanese emphysema patient with the AAT deficiency variant originally identified as S(iiyama). After an 8-year follow-up period, the patient suffered from repeated pulmonary pseudomonas aeruginosa infection for 4 years. He died suddenly of massive pulmonary hemorrhage. The pathologic examination revealed a necrotic hematoma in the right S10 lobe, which exhibited pneumonia due to cytomegalovirus (CMV) infection. Pulmonary hemorrhage due to CMV can occur and be fatal in patients with emphysema and AAT deficiency.- - - - - - - - - - ranking = 1.5keywords = infection (Clic here for more details about this article) |
5/201. rhinovirus infections in myelosuppressed adult blood and marrow transplant recipients.Scant data are available on the clinical significance of rhinovirus infections in immunocompromised patients. We reviewed the clinical courses of and outcomes for 22 myelosuppressed adult blood and marrow transplant recipients with rhinovirus infections who were hospitalized at the M.D. Anderson Cancer Center (Houston) from January 1992 to January 1997. In 15 patients (68%), illnesses remained confined to the upper respiratory tract. Seven patients (32%) developed fatal pneumonia. These patients had profound respiratory failure a mean of 12 days (range, 3-21 days) after the onset of symptoms. In six of these seven cases, rhinovirus was isolated before death from a bronchoalveolar lavage fluid specimen and/or an endotracheal aspirate. Five patients underwent autopsies, one of which revealed disseminated aspergillosis and four of which revealed interstitial pneumonitis and/or acute respiratory distress syndrome and no other organisms. In conclusion, rhinovirus infections may be associated with considerable pulmonary-related morbidity and mortality in severely myelosuppressed immunocompromised patients.- - - - - - - - - - ranking = 1.75keywords = infection (Clic here for more details about this article) |
6/201. cytomegalovirus pneumonitis as an initial presentation in an hiv-infected patient.Human immunodeficiency (hiv) infection often presents with an unusual symptom complex. Although cytomegalovirus (CMV) is a frequent opportunistic infection in the late stage of acquired immunodeficiency syndrome (AIDS), CMV pneumonitis as an initial manifestation of hiv infection is not documented in the medical literature. We report a previously healthy patient with bilateral interstitial pulmonary infiltrates who was found to have CMV pneumonitis; only later was hiv virus infection diagnosed. cytomegalovirus is a frequently isolated pathogen from respiratory secretions in AIDS patients. The role of CMV as a sole pulmonary pathogen is controversial. After exclusion of other pathogens, CMV was demonstrated by histological changes and viral culture in our case. This case indicates that pulmonary infiltrates presenting as the first manifestation of hiv infection can be caused by CMV infection.- - - - - - - - - - ranking = 1.5keywords = infection (Clic here for more details about this article) |
7/201. Varicella pneumonia complicated by acute respiratory distress syndrome in an adult.Primary varicella infection is uncommon in adults, but carries a higher rate of morbidity and mortality than in children. pneumonia is the most common complication of primary varicella infection in adults. However, varicella pneumonia complicated with acute respiratory distress syndrome (ARDS) is very rare. We report a case of ARDS secondary to varicella pneumonia in a 26-year-old man with primary varicella. The patient was otherwise healthy and had no evidence of human immunodeficiency virus infection. The initial chest radiograph showed bilateral reticulonodular infiltrates, which quickly evolved to diffuse alveolar consolidations. Arterial blood gas analysis revealed a ratio of arterial partial pressure to fraction of inspired oxygen of 87. Abnormal liver function and thrombocytopenia were also noted. Treatment consisted of mechanical ventilatory support and intravenous administration of acyclovir. His pulmonary condition gradually improved and he was successfully weaned from the ventilator 1 week later. He was discharged on the 15th hospital day with a favorable outcome. His pulmonary function improved progressively, with normal spirometry and lung volumes, but persistent mild impairment of diffusing capacity, 6 months after discharge.- - - - - - - - - - ranking = 0.75keywords = infection (Clic here for more details about this article) |
8/201. Influenza pneumonia in a paediatric lung transplant recipient.Although a common cause of morbidity and mortality in the general population, influenza infections are uncommon in lung transplant recipients and, to date, have only been associated with transient declines in pulmonary function and a relatively benign clinical course. This paper describes severe influenza pneumonia in a 13-year-old paediatric lung transplant recipient (5 months after double lung transplantation). Influenza pneumonia was diagnosed by direct fluorescent antibody testing and viral culture of bronchoalveolar lavage fluid. The patient required mechanical ventilation for 2 days due to respiratory failure and fatigue. Since his recovery from this pneumonia, he has developed obliterative bronchiolitis and currently awaits re-transplantation.- - - - - - - - - - ranking = 0.25keywords = infection (Clic here for more details about this article) |
9/201. Neonatal herpes simplex virus type II.This description of a tragic case of infection with neonatal herpes simplex virus type II is presented to alert professional nurses to the fact that this disease is sometimes difficult to recognize, but must be considered when a newborn has any unusual symptoms. Neonatal herpes simplex type II may have a slow and insidious onset, and be masked by many other symptoms. Even though the virus might be present in a newborn, the symptoms might not be apparent until several days after birth; this is a problem because infants are now leaving hospitals much earlier and can become ill after hospital discharge. parents, especially first-time parents, may not recognize subtle signs of illness in their child. Therefore, the onus is on the health care provider to evaluate each infant for symptomatology and provide education to parents along with instructions to obtain early follow-up care for all newborns.- - - - - - - - - - ranking = 0.25keywords = infection (Clic here for more details about this article) |
