Objective To investigate the clinical characteristics of nosocomial infections in senile inpatients(≥75 years old) and to propose the control strategy according to the analysis. Methods A total of 2675 senile inpatients(≥75 years old) from 2007 to 2008 were prospectively evaluated and retrospectively reviewed. The infection incidence rate, infection fatality rate, average length of stay in hospitals, location of infections, main pathogenic bacteria and common protopathy were analyzed. Results Among 2675 senile inpatients, 222 senile inpatients suffered from nosocomial infection. Among all age groups in this hospital during the same period, the infection incidence rate and the infection fatality rate were higher in the senile group than in the general group(8.3% vs. 1.9%, 0.8% vs. 0.1%,both P<0.01). The average length of stay in our hospital was 54.0 days. The lower respiratory tract infections were most common, and the urinary system infections, and the blood infections. Gram-negative bacteria was the major source of nosocomial infection(47.0%, 110/234), while infection rate of Gram-positive bacteria was 32.9% (77/234) and fungus was 20.1% (47/234). The cerebral vascular disease was the most common protopathy, then malignant tumor was in 45 cases (20.3%), kidney disease was in 31 cases(14.0%), cardiac disease was in 29 cases(13.1%) and respiratory disease was in 21 cases(9.5%). Conclusions There are higher infection incidence rate, higher infection fatality rates,longer length of stay in hospitals in senile inpatients(≥75 years old). The lower respiratory tract infections were most common and Gram-negative bacteria was the major source of nosocomial infection. We should adopt active management to control the nosocomial infections.

Objective To analyze the clinical characteristics of dopa-responsive dystonia (DRD). Methods The clinical characteristics and the causes of misdiagnosis in 15 patients with DRD were reviewed retrospectively.Results 4 male and 11 female patients were investigated in this study. The age at DRD onset was from 3~25 years old,the average age was 11.7 years old.The courses ranged from 2 to 29 years and the average was 12.1 years. The symptoms in female patients often aggravated during gravidity and delivery. Main clinical features included gait irregularity, postural instability and tremor, with marked diurnal fluctuation. The disease may be misdiagnosed as cerebral palsy, idiopathic torsion dystonia, essential tremor, parkinson's disease, neurosis and so on. All the patients in this study improved obviously in 2 weeks after therapy with low dose of Madopar, and recovered in 2~4 years of follow up.Conclusions Clinical diversity and diurnal fluctuation are the characteristics of DRD. Early trial treatment with low dose of Levodopa should be highly recommended for the generalized dystonia in children and untypical adults.
