Objective To investigate the clinical characteristics of patients with polypoidal choroidal vasculopathy (PCV) from Central China . Methods This was a retrospective study, and 403 eyes of 362 patients diagnosed as PCV by ocular fundus photography, fundus fluorescein angiography (FFA), indocyanine green angiography (ICGA) and optical coherence tomography (OCT) were enrolled. The general clinical data, fundus manifestation and ocular fundus examinations were statistically analyzed. Results Three hundred and sixty-two cases included 249 males (68.8%) and 113 females (31.2%). Age ranged from 45 to 91 years old, and mean age was (64.81plusmn;9.31) years old. Bilateral lesions were observed in 41 patients (11.3%) and unilateral lesions were observed in 321 patients (88.7%). In these 403 eyes, typical orangered lesions were observed in 162 eyes (40.2%); yellowishwhite exudate could be found in 185 eyes (45.9%); 268 eyes (66.5%) showed variable degrees of subretinal hemorrhage. Drusen was found in 23 eyes (5.7%), pigment proliferation in 20 eyes (5.0%) and fiber vascular scar in 96 eyes (23.8%). The lesions of 386 eyes (95.8%) located in macular region, 53 eyes (13.2%) in peripapillary area. Lesions presented multifoci in 67 eyes (16.6%). Three hundred and four eyes (75.4%) presented typical polypoidal lesions and 152 eyes (37.7%) with abnormal branching choroidal networks. Hemorrhagic retinal pigment epithelial detachments (PED) were found in 200 eyes (49.6%) and serous PED in 96 eyes (23.8%), both existed in 25 eyes(6.2%). OCT showed 56 eyes (13.9%) presented cystoid dark chamber between the neurosensory retina and 109 eyes (27.0%) with double-layer sign formed by the separation of retinal pigment epithelium and Bruchprime;s membrane (27.0%). Two hundred and seventy-four eyes (68.0%) were found with conelike elevation beneath the RPE layer and 151 eyes (37.6%) with neurosensory detachment. Conclusions In Central China, the majority of PCV patients were male, unilateral. Most PCV lesions were located in the macula. Subretinal hemorrhage, polypoidal lesions and abnormal choroidal vascular networks were common in the PCV patients. Hemorrhagic PED presented a higher ratio than serous PED.
Objective To investigate the etiological and clinical characteristics of the outbreak of hand-foot-mouth disease (HFMD) in Chengdu in 2008. Methods A retrospective analysis was conducted to investigate 482 children with hand-foot-mouth disease in Chengdu from January to December 2008 in terms of epidemiology and clinical characteristics. Results Among the 482 children, 76.14% of the cases were infants, and male children numbered more than female ones. The proportion in the urban area was higher than that in the rural area. May to July was the peak epidemic period. Skin rash and fever were major clinical manifestations. Three cases were diagnosed as viral encephalitis. Conclusion The incidence of hand-foot-mouth disease is related to age and season. Effective prevention measures and isolated treatment are critical for prevention and therapy.
Objective To investigate the drug resistance and homogeneous analysis of Acinetobacter baumanii in emergency intensive care unit ( EICU) . Methods Four multidrug-resistant Acinetobacter baumannii ( MDR-Ab) strains isolated fromnosocomial inpatients fromJuly 25 to September 7 in 2009 were collected and tested for drug sensitivity and MIC determination as well. The A. baumannii isolates were typed with pulsed-field gel electrophoresis ( PFGE) to determine whether they derived fromthe same clone.Results Four isolates from nosocomial inpatients were resistant to multiple antibiotics including carbapenem. The PFGE types identified from four isolates were A and B. The A. baumannii isolates did not derived from the same clone. Conclusion The prevalence of nosocomial infection is not due to transmission of the same strains among different individuals in EICU.
Objective To determine the incidence of and risk fact ors for retino pathy of prematurity (ROP) among preterm infants in Beijing after implementation of the ROP guidelines. Methods The preterm infants with birth weight le; 2000 g or gestational age le; 3 4 weeks who were admitted to the neonatal intensive care units in 6 hospitals in Beijing from Jan. 1, 2005 to Dec. 31, 2005 were screened. Ophthalmologic examin ations started 3-4 weeks after birth and ROP was classified by the revised Inte r national Classification. Maternal and perinatal risk factors of occurrence of R OP were analyzed. Results In the 639 infants who had been scre ened in the 6 ho spitals, ROP was detected in 69 (10.8%), in whom 23 infants (39 eyes) (3.6%) had type 1 ROP and underwent photocoagulation. The lower the birth weight and small er the gestational age was, the higher the incidence of ROP was. Logistic regres sion analysis indicated that low birth weight, apnea gt;20 seconds, anemia, hypoxic-ischemic encephalopathy and placenta abruption were the high risk factor of R O P.Conclusion In Beijing the incidence of ROP is 10.8% after i mplementation of the ROP guidelines. Low birth weight, apnea gt;20 seconds, anemia, hypoxicischem ic encephalopathy and placenta abruption were the high risk factor of ROP.
Objective To investigate the prevalence and related factors of diabetic retinopathy (DR) among residents with type 2 diabetes mellitus (T2DM) in Culai Town of Tai'an City in Shandong Province. Methods According to the DM management file database for community, 785 patients with T2DM were randomly selected by cluster sampling method. The questionnaires, routine general examinations, visual and fundus-free fluoroscopy were performed on all the patients. DR diagnosis and classification was according to the guidelines for clinical diagnosis and treatment of DR in China (2014). Both monocular and binocular DR were selected as DR patients, and the worse eye for binocular DR were treated as the DR classification of the patient. The patients were grouped by presence or absence of DR. GraphPad Prism 6, SigmaPlot 12.5, SPSS 20.0 and Excel were used to achieve data analysis. Also, SPSS 20.0 was used for multi-factor logistic regression analysis. Results A total of 699 patients (89.04%) were actually recorded. There were 122 eyes of 63 patients (9.01%) with DR (DR group), 1272 eyes of 636 patients (90.99%) without DR (NDR group). Among the 122 eyes of DR, there were 19 (15.57%), 17 (13.93%), 70 (57.38%), 10 (8.20%), 6 (4.92%) eyes in stage Ⅰ, Ⅱ, Ⅲ, Ⅳ, Ⅴ, respectively. The differences of mean age (t=15 290, P=0.002), DM duration (t=9075, P<0.000) and diastolic blood pressure (t=15 810, P=0.006) between the two groups were statistically significant. There were 23 (36.51%) and 394 (61.95%) patients with hypertension history in the DR group and the NDR group, with the significant difference ( χ2=15.42, OR=0.35, 95%CI 0.21-0.60). There were 57 (90.48%) and 500 (78.62%) patients with fasting blood glucose larger than 6.11 mmol/L in the DR group and the NDR group, with the significant difference (OR=2.51, 95%CI 1.06-5.95, P=0.031). Logistic regression analysis showed that the age, fasting blood glucose and DM duration were influencing factors for DR (OR=1.039, 0.864, 0.898; P=0.021, <0.000, <0.000). Conclusion The prevalence of DR in patients with T2DM in Culai Town of Tai'an City is 9.01%. Age, DM duration, fasting blood glucose are associated to DR. Those with a history of hypertension may have a lower risk of DR than those without a history of hypertension.
Objective To analyze the epidemiological features of clavicle fractures.Methods A total of 363 cases of clavicle fractures were treated from February 1993 to November 2002, their case history data were reviewed and evaluated by epidemiological method.Results Out of 363 cases, there were 269 males and 94 females, aged from new born to 96 years. The locations of fractures were on left side in 159 cases and on right side in 204 cases. Neonatal clavicle fracture occurred in the case of delivery (0.28%). The causes of disease for adult clavicle fractures were traffic injury (52.1%) and daily falling injury(31.1%). There were232 cases of simple fractures and 131 cases of comminuted fractures. The fracture positions included inner(6 cases), middle(328 cases) and outer parts(29 cases). Multiinjuries occurred in 78 cases, the rib fractures concomitant with clavicle fractures were the commonest(31 cases).Conclusion The clavicle fractures are the common injury. Of them, traffic injury and daily falling injury arethe most common. The rib fractures are always accompanied with clavicle fractures.The main position of fracture is on the middle part.
