1/48. 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 = 1keywords = pneumonia (Clic here for more details about this article) |
2/48. 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 = 0.85714285714286keywords = pneumonia (Clic here for more details about this article) |
3/48. nitric oxide in the treatment of fulminant pulmonary failure in a young pregnant woman with varicella pneumonia.extracorporeal membrane oxygenation is the recommended treatment for fulminant pulmonary failure due to varicella pneumonia. However, in pregnancy fetal viability during extracorporeal membrane oxygenation is generally poor resulting in either therapeutic or spontaneous abortion. The present case is to our knowledge the first report on the treatment with nitric oxide to improve oxygenation in a pregnant woman with fulminant pulmonary failure due to varicella pneumonia. Adding 20 parts per million nitric oxide to the inspiratory gas increased arterial oxygen saturation from 75 to 88%, and it could be kept at this level. Due to a vaginal bleeding, an emergency Caesarean section was performed with successful outcome for the fetus. The mother started to improve after delivery and could be weaned from nitric oxide after 5 days. We conclude that inhalation of nitric oxide may be a good alternative to extracorporeal membrane oxygenation in the treatment of fulminant pulmonary failure due to varicella pneumonia in pregnancy.- - - - - - - - - - ranking = 1keywords = pneumonia (Clic here for more details about this article) |
4/48. Disseminated vaccine strain varicella as the acquired immunodeficiency syndrome-defining illness in a previously undiagnosed child.The food and Drug Administration licensed a live-virus varicella vaccine (Varivax; Merck & Co Inc, West Point, PA) in March 1995. Prelicensure adverse events were minimal; however, since licensure and increased vaccine use, rare previously undetected risks have arisen. Presented here is the clinical course of a previously undiagnosed, human immunodeficiency virus-infected boy who developed dissemination of the vaccine strain of varicella zoster after immunization. chickenpox, human immunodeficiency virus, pneumonia, encephalopathy, varicella vaccine, adverse events, dissemination.- - - - - - - - - - ranking = 0.14285714285714keywords = pneumonia (Clic here for more details about this article) |
5/48. An unusual varicella zoster infection complicated by purpura fulminans and multiorgan failure in a healthy infant.The case is reported of a 2-y-old boy who developed purpura fulminans, meningoencephalitis, pneumonia complicated by adult respiratory distress syndrome and acute renal failure after varicella. These complications of varicella are extremely rare in a healthy infant.- - - - - - - - - - ranking = 0.14285714285714keywords = pneumonia (Clic here for more details about this article) |
6/48. fatal outcome of varicella in children.Varicella or chicken-pox are one of the most frequent diseases in childhood. Severe or even lethal complications are rare (in about 0.03 per thousand ). Our paper presents two cases of varicella infections leading to sudden deaths (3- and 7-year-old children). In one of these cases, the paediatrician in charge was accused of an impaired medical treatment. Both of the children showed multiple typical efflorescences in different stages. Furthermore were observed affections of the respiratory tracts and serious involvements of the hearts, the lungs, and the livers. In one case an immunological identification could be made of an acute varicella infection. Based on autoptical, histological, bacteriological, virological, and neuropathological findings is given an analysis of such uncommon and severe courses of chicken-pox in children being identified as haemorrhagic form and massive abscess-forming varicella pneumonia.- - - - - - - - - - ranking = 0.14285714285714keywords = pneumonia (Clic here for more details about this article) |
7/48. Membranoproliferative glomerulonephritis with partial lipodystrophy: discordant occurrence in identical twins.The course of disease of a patient with membranoproliferative glomerulonephritis and partial lipodystrophy is described. The case is further characterized by a deficiency of C3 and C3- activator, by normal values of C4, by evidence of the nephritogenic factor, by raised fibrin degradation products and by an unselective proteinuria. The course of the glomerulonephritis runs parallel to a pronounced susceptibility to infection (at first varicella, tonsillitis and measles, later pneumonia, meningitis, encephalitis and hepatitis). On account of a nephrotic syndrome and an initative impairment of the renal function, a cytostatic treatment was begun, which although raising the C3 level did not influence the further course of the disease. As the patient has a healthy identical twin sister without lipodystrophy, who shows no reduction in C3 and no nephritogenic factor, this case proves that these diseases are acquired and not genetically determined.- - - - - - - - - - ranking = 0.14285714285714keywords = pneumonia (Clic here for more details about this article) |
8/48. Emergence of invasive group A streptococcal disease among young children.Eight cases of invasive group A streptococcal disease in young children were reported over a three-month period, February to April 1990. The spectrum of clinical disease included: pneumonia with bacteremia (two patients), osteomyelitis/septic arthritis (three patients), epiglottitis/supraglottitis (two patients), and sepsis without a focus (one patient). Three cases followed chicken pox. Three children were in shock at the time of presentation, including one child who had a toxic shock-like appearance. Only four children had pharyngitis. bacteremia was confirmed in three children and presumed in another three. All the subjects survived. Four isolates of group A streptococci were tested for exotoxin A, B, and C (A-0, B-4, C-1) production. These data confirm the reappearance of a highly invasive strain of group A streptococci capable of producing a variety of clinical diseases, including bacteremia and shock, in a significant proportion of victims.- - - - - - - - - - ranking = 0.14285714285714keywords = pneumonia (Clic here for more details about this article) |
9/48. Varicella pneumonia in adults. A review of pulmonary manifestations, risk factors and treatment.pneumonia is a rare but serious and occasionally fatal complication of varicella. Two cases of varicella pneumonia were successfully treated with acyclovir in our department. We reviewed the pulmonary manifestations of varicella, the risk factors and the effect of acyclovir on varicella pneumonia on immunocompetent adults. Early, aggressive therapy with acyclovir seems to abort the catastrophic consequences of varicella pneumonia, while oral acyclovir chemoprophylaxis is probably beneficial in high-risk populations with chickenpox.- - - - - - - - - - ranking = 1keywords = pneumonia (Clic here for more details about this article) |
10/48. Infectious disease capsules: a pox on your house.A 31-year-old, previously healthy white man presented to the emergency department with complaints of malaise, fevers, shortness of breath, a non-productive cough, and a "rash." His physical exam revealed a temperature of 100.2F, a pulse of 129 bpm, respiratory rate of 14 BPM, and blood pressure of 140/74 mm Hg. He was alert, oriented, and in no distress. His oropharynx was dry, his neck was supple, and cervical lymphadenopathy was absent. He had tachycardia, bilateral wheezes, and rhonchi with prolonged expirations. There was a diffuse vesicular eruption enveloping his entire body with involvement sparing his palms and soles (Figures 1 and 2). Laboratory values showed a hemoglobin of 16.0 g/dL and a white blood cell count of 7100 cells/pL, with 39%neutrophils, 23% bands, and 35% lymphocytes. His platelet count was mildly decreased to 86,000 x 103/pL. Chest radiograph revealed bilateral diffuse interstitial infiltrates. A diagnosis of acute varicella-zoster virus pneumonia (varicella pneumonia) was made, and the patient was started on IV acyclovir (10 mg/kg every 8 hours). Upon further questioning, the patient stated that his daughter had been diagnosed with "chickenpox" 7 days ago. The patient had numerous exposures to chickenpox in the past but had never developed clinical expressions of varicella. He was not at risk for hiv infection, not having multiple sexual partners, IV drug abuse, or blood transfusions. During the 1 day of in-hospitalization, his fever abated and the pulmonary signs diminished.Following discharge, IV acyclovir was replaced by valacyclovir to complete a 7-day course of therapy.- - - - - - - - - - ranking = 0.28571428571429keywords = pneumonia (Clic here for more details about this article) |
