Primitive neuroectodermal tumour in a 60-year-old man: a case report and literature review.

Primitive neuroectodermal tumour (PNET) is very rare, especially in adults. We report a 60-year-old man presented with a PNET. The symptoms at the time of diagnosis were intense headache, Broca's aphasia and right hemiparesis. Only an open biopsy was performed. Irradiation of the primary tumour was the main treatment (total tumour dose 59.8 Gy) because of serious haematological side effects due to chemotherapy. The patient tolerated radiation therapy extremely well and his neurological symptoms were improved. 1 month after completion of radiotherapy, MRI showed no regression of the tumour. Clinical deterioration was observed 10 months after the initial diagnosis and the patient died 2 months later. In cases of PNET, initial therapy is surgical bulk reduction whenever possible. Irradiation of the cerebrospinal axis is justified as a routine treatment but, owing to the radioresistance of the tumour, the addition of multiregimen chemotherapy appears to improve survival, according to the literature.

Bacterial pneumonia as a suprainfection in young adults with measles.

The aim of this study was to report the clinical and laboratory characteristics of bacterial pneumonia related to measles infection, and also to assess any correlation between severity and time of onset. Four hundred and twenty-four previously healthy young males (age 22+/-2.1 yrs) were hospitalized with typical symptoms and signs of measles. One hundred and twelve (26%) developed bacterial pneumonia on admission (n=41), during their hospital stay (n=20) or days after their discharge (n=51): groups A, B and C, respectively. Single lobar consolidation was the most common finding, accounting for 89% of cases. Pleural effusion was uncommon and associated in half of the cases with empyema. A microbiological diagnosis was made in 81 cases. Streptococcus pneumoniae (65 cases) and Klebsiella pneumoniae (9 cases) were the most commonly identified organisms. Patients from group C had significantly higher values of white blood cell count and erythrocyte sedimentation rate, and lower values of arterial oxygen tension (14+/-0.8 x 10(9) x L(-1), 88+/-4 mm and 6.3+/-0.4 kPa (47+/-3 mmHg), respectively) than the other two groups. There were no deaths during the hospitalization period. The mean duration of hospital stay was 13+/-2.4 days and was longer in the presence of K. pneumoniae infection (19+/-1.6 days). Six patients from group C were admitted to the intensive care unit. In conclusion, these data suggest that bacterial pneumonia associated with measles is not unusual in hospitalized adults, and it seems to be more severe when it occurs days after the onset of rash.
