Objective To investigate the clinical features of unintentional injuries in children,and to provide the theoretical basis for preventing and intervening the occurrence. Methods We collected the data of children aged from 0 to 14 years old and hospitalized in the First Affiliated Hospital of Guangxi Medical University from January 2013 to December 2015. Results There were 2286 cases of children including 1507 boys(65. 92%) and 779 girls(34. 08%). The high incidence age was 1 to 3 years with a total of 896 cases(39. 19%). The first five causes of unintentional injuries were burns/scalds 840 cases(36. 71%),fall/drop 464 cases(20. 30%),blunt force injury 290 cases(12. 68%),foreign bodies(in the esophagus,airway, etc) 253 cases(11. 07%),and sharp object injury 153 cases(6. 68%). The unintentional injuries of different age group were varied,for example,the common causes of 1 to 3 years old group were burns /scalds and for-eign bodies(in the esophagus,airway,etc),and the main injuries in 6 to 14 years old group were fall/drop and blunt force. Furthermore, the proportion of unintentional injuries in rural children was 1547 cases (67. 67%),and in the urban children was 739 cases(32. 33%). Unintentional injury with serious conse-quences included burns/scalds 55 cases(26. 96%),sharp object injury 45 cases(22. 06%),burns/scalds 26 cases (12. 75%),blast injury of 23 cases(11. 27%) and fall/drop 20 cases(9. 80%). Disable/sequel hap-pened in 204 cases(8. 92%). Ten cases died(0. 44%) including fall/drop in 4 cases,traffic accident in 3 cases(30%). Conclusion Young children aged 1 to 3 years are the most vulnerable to unintentional inju-ries. Burns/scalds and foreign bodies( in the esophagus,airway,etc) are the most common causes of injuries, and the boys are more common than girls. Moreover,the incidence rate of unintentional trauma in rural chil-dren was higher than that in the urban children. Unintentional injury complicated serious consequences are burns/scalds,sharp object injury,blast injury and fall/drop. Death cases in the majority are fall/drop and traf-fic accident. The key to reduce the occurrence of unintentional injuries is to strengthen propaganda of preven-tion knowledge about the children′s unintentional injuries.

Objective To investigate the clinical, imaging and pathological findings of the primary (CNS) lymphoma in patients without AIDS. Methods The clinical, laboratory, neuroradiological and pathological data of such 15 cases were analysed. Results The clinical features of the primary malignant lymphoma of CNS are variable,however,more than half of patients were presented with an increased intracranial pressure and a neurologic dysfunction, such as weakness of limbs,speech changes and seizures. These symptoms were always misdiagnosed as some other tumors.Examination of CSF revealed a mild or intermediate increase of protein in all patients by way of lumbar punctures. Imaging examinations by CT and MRI both showed solitary or multiple masses of tumor located more likely in the frontal and temporal lobes. Only 20% patients mimiced the demyelineting disease and were misdiagnosed as multiply sclerosis. Conclusions Patients with such CNS lymphoma usually do not present the characteristically clinical manifestations or findings in the imaging scanning. Brain biopsy may be a method more reliable to confirm this disease and be important for improving the prognosis of patients.

Objective To study the multi-slice spiral CT (MSCT) manifestations of septic pulmonary embolism(SPE) in order to get a better understanding of the disease,Methods The MSCT manifestations of 12 patients with septic pulmonary embolism were retrospectively analyzed and compared with chest radiograph.Results Of the 12 patients,Chest radiograph and CT scanning showed multiple peripheral pulmonary nodules in 8 and 12 cases,a feeding vessel sigu(0,9 cases),cavitations(6,10 cases) and wedge-shaped opacities(4,7 cases),focal infiltrates(2,4 cases),air cyst(2,5 cases),pleural lesions (3,6 cases),hilar or mediastinal lymphadenopathy(0,3 cases).Peripheral or subpleural zones were most commonly affected (8,12 cases).CT was more useful in revealing nodules and a feeding vessel sign.Multiplanar reconstructions (MPR),maximum intensity projection (MIP) showed that most of these vessels passed around nodules and wedge-shaped lesions.MPR showed regular nodular margin.Conclusion SPE presents with variable and often nonspecific clinical and radiographic features.MPR and MIP showed the features of nodules and feeding vessels better.The diagnosis is usually suggested by the presence of a predisposing factor,febrile illness,and CT findings of multiple,periphery pulmonary nodules,with orwithout cavitation and a feeding vessel sign.

Objective To evaluate the impact factors on weight and proportion of prostate tissue resected by transurethral resection of prostate (TURP) in patients with benign prostatic hyperplasia (BPH). Methods The patients undergoing TURP from January 2007 to June 2009 and diagnosed as BPH according to postoperative pathological results were enrolled in this study. The prostate volume measured by transrectal ultrasound (TRUS), prostate specific antigen (PSA), maximum flow rate (MFR), residual urine volume and body mass index (BMI) were measured and calculated. The prostate tissue collected at resection was weighed, and the proportion of the prostate resected was the percentage of the pre-operative estimated weight. Results For the 458 patients with the average age of 69.5 years, average BMI was 24. 3 kg/m2 , PSA 6. 1 μg/ml, prostate volume 85.5 ml, MFR 8. 4ml/s, residual urine volume 31.8 ml, resected prostate weight 32.9 g, proportion of resection 37. 6%Prostate volume and BMI were positively related with resected prostate weight. BMI was positively related with proportion of prostate resection. There was no linear correlation between prostate volume and resected proportion. But there was significant difference in resected proportion between patients with prostate volume more than and less than 40 ml. Finasteride had no influence on the weight and resected proportion. Conclusions Prostate volume, PSA and BMI are correlated with weight and proportion of prostate tissue resected by TURP. Finasteride has no influence on the resected weight and proportion.

Objective To discuss the prostate biopsy results in young men with age less than 50 years and with PSA 4-10 μg/L.Methods From January 2006 to December 2011,22 patients with PSA 4-10 μg/L underwent prostate biopsy for free/total PSA ≤ 0.16 (20 cases) and/or positive digital rectal examination (DRE) (4 cases).The nean age was 43 years (range,24-49 years),the mean PSA level was 7.08 μg/L (range,4.17-9.74 μg/L),the mean free/total PSA level was 0.11 (range,0.03-0.53).Radiologic suspicious lesion was founded in 13 cases.Clinicopathological data from these patients were reviewed.Results The results of the biopsy were 1 (4.5％) case of prostate cancer,2 cases (9.1％) with tuberculosis,9 cases (40.9％) with inflammation,10 cases (45.5％) with benign tissue.In 20 cases with free/total PSA ≤0.16,only 1 case was diagnosed as prostate cancer.In 4 cases with positive DRE,tuberculosis (2 cases) and inflammation (1 case) were diagnosed.Conclusions The prostate cancer detection was rare in young men less than 50 years of age with PSA 4-10 μg/L.The most common cause was prostate hyperplasia with inflammation.
