Necrotizing adenoviral pneumonia: manifestation of nosocomial infection in pediatric intensive care unit.

A 5-year-old child admitted in the pediatric intensive care unit developed fever and crepitations in the chest on 6(th) day of admission. She succumbed to her illness depite administration of adequate supportive and ventilatory care and anti-microbial therapy. At autopsy, she was diagnosed to have chronic ligneous type of tuberculous meningitis and necrotizing adnoviral pneumonia. There are hardly any reports of nosocomial adenoviral pneumonia from Indian centers. The case serves to remind intensivists to consider this diagnosis so that appropriate therapeutic adjustments and measures to prevent the spread of infection to other critically ill subjects are initiated.

Pathology of pulmonary aspergillomas.

Aspergilloma refers to a fungal ball formed by saprophytic overgrowth of Aspergillus species and is seen secondary to cavitatory/cystic respiratory diseases. Paucity of clinical and pathological data of aspergilloma in India prompted us to analyze cases of aspergilloma over 15 years. The clinical features were recorded in all and correlated with detailed pathological examination. Aspergillomas were identified in 41 surgical excisions or at autopsy. There was male predominance; half the patients were in their fourth decade. Episodic hemoptysis was the commonest mode of presentation (85.4%). Forty aspergillomas were complex, occurring in cavitatory lesions (82.9%) or in bronchiectasis (14.6%). Simple aspergilloma was seen as an incidental finding in only one. Tuberculosis was the etiological factor in 31 patients, producing cavitatory or bronchiectatic lesions; other causes were chronic lung abscess and bronchiectasis (unrelated to tuberculosis). Surgical resections are endorsed in view of high risk of unpredictable, life-threatening hemoptysis.

Pulmonary endarteritis.

Pulmonary arterial endarteritis is a rare event even in patients with congenital heart disease. In this paper, the authors report two cases of pulmonary endarteritis diagnosed at autopsy. The first was a 3-month-old male infant with absence of congenital heart defect (who had had neonatal sepsis). This patient presented with pneumonia and succumbed within 36 hours of hospital stay despite appropriate antimicrobial therapy and supportive management. The second patient was a 13-month-old male child with previously undiagnosed tetralogy of Fallot who had clinical presentation of acute meningitis with convulsions and succumbed within 12 hours of hospital stay despite adequate treatment. The main autopsy findings were chronic arteritis of the pulmonary trunk and right pulmonary artery in the former and rupture of the pulmonary trunk in the latter.

Valvular vegetations? Cardiac amyloidosis is a possibility.

Cardiovascular system is a frequent target for the deposition of amyloid, specially in the primary type. Patients with this condition can present with myocardial dysfunction due to heavy interstitial myocardial deposits. We report a case of primary cardiovascular amyloidosis in a male with sudden cardiac death. The distribution of amyloid was remarkable for exclusive deposition in the pulmonary and systemic arterial adventitia and more strikingly over all valves, specially the mitral valve. These were large enough to simulate vegetations.
