ObjectiveTo evaluate the efficacy and safety of half-dose verteporfin photodynamic therapy (PDT) for chronic central serous chorioretinopathy (CSC). Methods35 eyes (35 patients) with chronic (or recurrent) CSC treated with half-dose verteporfin PDT. Best-corrected visual acuity(BCVA), central macular thickness (CMT) were measured before and after treatment (1, 3 and 6 months). The mean BCVA was 0.28±0.22, mean CMT was(384.5±85.0)μm. The situation of subretinal fluids (SRF) absorption was observed. ResultsIn 35 eyes, SRF of 29 eyes (82.9%) completely absorbed and 6 eyes (17.1%) not completely absorbed after one month of treatment. SRF of all eyes (100.0%) completely absorbed after three months of treatment. After 6 months of treatment, SRF of 3 eyes (8.6%) were recurrence, which might be completely absorbed when a half-dose maintenance therapy PDT was used again. The mean BCVA significantly improved to 0.14±0.13 at 1 months, 0.05±0.11 at 3 months and 0.05±0.12 at 6 months after PDT (t=5.410, 7.830, 7.758; P < 0.05). The mean CMT decreased to (224.3±61.4) μm at 1 months, (199.6±32.7) μm at 3 months and (205.3±39.6) μm at 6 months after PDT (t=11.856, 11.781, 11.900; P < 0.05). The mean CMT of controlled 32 eyes after treatment was (198.5±33.9) μm, much lower than the fellow eyes(232.3±17.5) μm (t=-3.988, P < 0.05). ConclusionsHalf-dose verteporfin PDT was safe and effective in treating chronic CSC, but may cause thinning of CMT.
Objective To explore the clinical characteristics and management of ovarian tumor complicated by pregnancy and its influence on the pregnancy outcome, so as to provide diagnostic and therapeutic experiences. Methods A total of 248 cases were surgically and pathologically diagnosed as ovarian tumor complicated by pregnancy in The 202 Military Hospital from January, 2003 to December, 2009, and their clinical data were analyzed retrospectively. Results The incidence rate of ovarian tumor complicated by pregnancy was 0.49%. Among total 248 cases, 131 (52.82%) were benign tumors, of which 22.18% were ovarian mature teratomas; 113 (45.57%) were tumourlike lesions, of which most were ovarian chocolatecyst and lutealcyst, and 4 (1.61%) were malignant tumors. There were 212 cases treated by tumorectomy or salpingo-oophorectomy, and 3 of 4 cases with malignant tumors took postoperative chemotherapy. A total of 192 cases were diagnosed by regular antenatal care and ultrasound examination, accounting for 77.42% of the total sample size found during pregnancy. Among 14 cases receiving emergency operations, 9 were complicated by torsion, and the other 5 were by rupture. There were 67 cases receiving operation from the 14th to 18th gestational week, and 57 cases had full-time pregnancy. Conclusion Ultrasonography and pelvioscopy are of principal importance in the diagnosis and detection of ovarian tumor complicated by pregnancy which should be treated by tumorectomy, and suitable surgery intervention during second trimester is safe.
ObjectiveTo investigate the clinical characteristics of epileptics with pregnancy and then provide reference for standardized management of epileptics with pregnancy. MethodsFrom June 2012 to June 2021, epileptics with pregnancy who delivered in Jinan Central Hospital were selected as the research subjects. The clinical data such as the application of Antiseizure medications (ASMs) during pregnancy, seizure frequency, pregnancy outcomes, delivery ways, offspring feeding ways and the incidence of complications were investigated and analyzed. ResultsAmong 36 epileptics with pregnancy, 20 cases (55.56%) were treated with ASMs alone, 5 cases (13.88%) were treated with combined medication, and 11 cases (30.56%) were treated without ASMs during pregnancy. 15 cases (41.67%) adhered to systematic application of ASMs, 17 cases (47.22%) did not adhere to systematic application of ASMs, and 4 cases (11.11%) had unknown medication history. The frequency of seizures increased in 5 cases, decreased in 7 cases and unchanged in 24 cases during pregnancy. Pregnancy outcomes: full-term delivery in 33 cases (91.67%), preterm delivery in 1 case (2.78%) and abortion in 2 cases (5.56%). Delivery mode: cesarean section in 31 cases (91.18%), vaginal delivery in 3 cases (8.82%). After delivery, 4 cases (11.76%) were fed with milk powder and 30 cases (88.24%) were breast-fed. Complications: There were 6 cases complicated with anemia (16.67%), 5 cases complicated with gestational hypertension (13.89%), 3 cases complicated with gestational diabetes (8.33%), 4 cases complicated with premature rupture of membranes (11.11%), 2 cases complicated with fetal growth restriction (5.56%), 2 cases complicated with oligohydramnios (5.56%), 3 cases complicated with fetal distress (8.33%) and 3 cases complicated with neonatal asphyxia (8.33%). ConclusionsThe proportion of epileptics with pregnancy who were systematically treated with ASMs was low and the seizures were poorly controlled. There is a lack of standardized management for such patients in clinical practice.
The use of core outcome sets reduces heterogeneity in the reporting of outcomes in clinical trials, increasing the value and significance of research. This paper first introduces and interprets “core outcome sets for myocardial infarction (COS-MI) in clinical trials of traditional Chinese medicine and Western medicine”, in order to help Chinese researchers better understand and use it. Second, this study surveyed the use of COS-MI in MI related clinical trials from January 1, 2023 to June 1, 2024, showing that 91% (10/11) of the 35 acute myocardial infarction clinical studies included reported core outcomes, and the median percentage of using core outcome sets was only 36% (4/11). As the publication time of the core outcome set is close to the literature search time, the understanding of domestic researchers about it is still unclear. Further research is needed to explore the application of core outcome sets for myocardial infarction in clinical trials of traditional Chinese medicine and Western medicine, providing a reference for its update and improvement.
ObjectiveTo evaluate the surgical outcomes of 25G+ vitrectomy with air tamponade and 1-day prone positioning for idiopathic macular hole (IMH).MethodsA prospective analysis was performed on 39 patients (39 eyes) underwent 25G+ pars plana vitrectomy (PPV) combined with the internal limiting membrane (ILM) removal and fluid-air exchange for IMH from July 2012 to December 2013. After vitrectomy, patients were instructed to keep prone positioning for only 1 day (the air group). These patients were compared to 30 consecutive patients from July 2010 to July 2012, who were conducted 25G+ PPV with 25% SF6 tamponade. They remained in the same face-down position for 3 days postoperatively (SF6 group). Age, gender, logMAR BCVA, macular thickness, macular hole diameter, axial length, macular hole stages and pseudophakic status were collected as baseline characteristics in both groups. The initial hole-closure rate, visual outcome and intra-operative & post-operative complications were evaluated for 6 months. Group comparisons of numeric variables were made by using two sample t -test. Group difference of categorical variables was determined by using standard chi-square test or rank sum test.ResultsThirty nine patients (39 eyes) and 30 patients (30 eyes) were respectively enrolled in air group and SF6 group. The distribution of age (t=－1.63), gender (χ2=0.03), logMAR BCVA (t=0.39), macular thickness (t=－0.93), macular hole diameter (t=－0.70), axial length (t=－0.56), macular hole stages (Z=－0.47) and pseudophakic status (χ2=0.13) was similar in both groups. Anatomical closure of macular holes was achieved in 35 (89.7%) of the 39 eyes in the air group and in 27 eyes (90.0%) in the SF6 group. There was no significant difference of closure rate between the two groups (χ2=0.001, P=0.970). The postoperative visual acuity of gaining, stability and decreasing 2 or more 2 lines was achieved in 23 eyes,10 eyes and 6 eyes in air group and 18 eyes, 6 eyes and 6 eyes in SF6 group. The proportion of visual acuity improvement in air group was lower than that in SF6 group without the statistical significance (Z=－0.08, P=0.93). The gas bubble was absorbed sooner in the air group (mean 8.54±1.74 days) than in the SF6 group (mean 31.10±3.20 days). No retinal break, retinal detachment or endophthalmitis occurred in either group. Postoperatively intraocular pressure was elevated temporarily in 2 eyes of the air group and 3 eyes in the SF6 group. All returned to normal limit after local medication.ConclusionCompared to SF6 group, air group has similar anatomical macular hole closure rate and visual acuity rehabilitation.
Objective To investigate the therapeutic effects of retinal angiomatosis in different clinical stages. To discuss the indication of vitrectomy for retinal hemangioblastoma. Methods The clinical data of 22 cases (33 eyes) were retrospectively analyzed. The retinal hemangiomas were divided into 5 stages according to their degrees of development from simple angioma without vessel dilation to feeder vessel dilation and intra-retinal exudates, local retinal detachment, massive retinal detachment and co mplication occurrence in proper order. The methods of treatment were laser photo coagulation, trans－scleral cryotherapy and vitrectomy. 13 eyes were treated with laser photocoagulation, 5 eyes with cryotherapy combined with laser and 11 eye s with vitrectomy. Tumor resection and silicone oil tamponade was performed in 3 eyes during vitrectomy. The patients were followed up for 46 months on average. Visual acuity (VA), the condition of the hemangioma and retina was compared pre- and post-operation respectively. Results In all 13 eyes treated with laser photocoagulation the hemangiomas regressed and the retina remained attached. VA improved in 2 eyes, and remained unchanged in 11 eyes. Cryother apy combined with laser photocoagulation was performed on 5 eyes. In this group, 4 eyesprime; hemangiomas regressed and no new hemangiomas occurred, proliferative vitreous retinopathy and vitreous hemorrhage was observed in 1 eye which vitrecto my was performed later. VA improved in 2 eyes, unchanged in 2 eyes and decreased in 1 eye. In the 11 eyes treated with vitreoretinal surgery, new hemangiomas wa s found in 1 eye, exudative retinal detachment was caused by hemangiomas in 2 eyes, proliferative vitreous retinopathy was observed in 2 eyes, and the retina re mained attached in 8 eyes. VA improved in 3 eyes, unimproved in 3 eyes, and decreased in 5 eyes. In the 3 eyes with surgical resection of retinal hemangioma during vitrectomy, 2 eyesprime; retina remained attached, 1 eye had exu dative retinal detachment and no new hemangiomas occurred. VA improved in 2 eyes and decreased in 1 eye. Conclusions Laser photocoagulation or combined with cryotherapy is effective in treating the hemangiomas in early stage. Vitrectomy is advisable for late stage of retinal angiomatosis, especially with vitreous hemorrhage, epiretinal membrane, proliferation and large scale of r etinal detachment. Surgical resection of isolated large retinal hemangioblastoma may be useful for selected patients. (Chin J Ocul Fundus Dis,2008,24:107-110)
Objective Exploring the correlation between intravesical pressure (IP) and diaphragm excursion (DE) in patients with severe acute pancreatitis (SAP) and acute respiratory distress syndrome (ARDS), and evaluating its predictive value for weaning outcomes. Methods A retrospective analysis was conducted on the clinical data of 144 SAP patients with ARDS admitted between 2020 and 2023. By collecting the outcome of weaning, collect data on gender, age, acute physiology and chronic health score II (APACHE II), oxygenation index, and IP and DE before weaning and extubation for all patients. Based on weaning outcomes, divide patients into successful and failed groups, and compare the differences in various indicators between the two groups; Use binary logistic regression to analyze whether IP and DE are risk factors affecting weaning in SAP patients with ARDS, and use Pearson correlation analysis to examine the correlation between IP and DE; Use receiver operating characteristic curve (ROC curve) to analyze the predictive value of IP and DE on weaning outcomes in SAP patients with ARDS. ResultsA total of 144 SAP patients with ARDS were included, of which 108 were successfully weaned and 36 were unsuccessful. There were no statistically significant differences in gender, age, and APACHE II scores between the successful and failed groups (males: 62.96% (68/108) compared to 69.44% (25/36), age (years): 41.91 ± 8.14 compared to 42.42 ± 6.22, APACHE II score (points): 18.28 ± 2.22 compared to 18.97 ± 1.83, P>0.05). The IP of the successful group was significantly lower than that of the failed group, and the DE was significantly higher than that of the failed group [IP (mmHg): 18.45 ± 3.76 compared to 23.92 ± 5.65, DE (mm): 16.18 ± 4.23 compared to 12.28 ± 4.44, all P<0.05]. All patients showed a significant negative correlation between IP and DE (r=–0.457, P<0.001). ROC curve analysis showed that the area under the curve (AUC) of IP predicting the withdrawal outcome of SAP patients with ARDS was 0.805, with a 95% confidence interval (95%CI) of 0.724-0.885 and P<0.001. When the cutoff value was 19.5 mmHg, the sensitivity was 91.57% and the specificity was 47.54%; The AUC for predicting the withdrawal outcome of SAP patients with ARDS by DE was 0.738, with a 95%CI of 0.641-0.834 and P<0.001. When the cutoff value was 11.5 points, the sensitivity was 84.82% and the specificity was 59.38%. Conclusions There is a significant negative correlation between IP and DE in SAP combined with ARDS patients, and both have certain predictive value for weaning outcomes.
Inconsistency, impracticability and non-standardization of the selection, measurement and reporting of outcomes are three primary existing issues in clinical trials. These problems pose a threat to huge research waste when the results of similar studies are not able to be combined or compared. The key for resolution will be to standardize outcomes in traditional Chinese medicine (TCM) clinical trials and to establish a core outcome set (COS), which is a set of outcomes to be reported as a minimum in all TCM clinical trials of similar healthcare system and syndromes. The first step in the development of COS is to collect all existing outcomes, that is, to build a pool of outcomes for clinical trials of TCM. A pool of outcome is the basis of developing COS, which is important to follow strict and scientific methodology. This paper aims to construct an outcome pool from published literature, clinical trial registration protocols, and clinicians, and patients questionnaires were used to form a list of outcomes. In addition, the influencing factors of constructing an outcome pool and considerations for each problem are summarized in order to provide guidance and reference for the development of COS in clinical trials for TCM.
Objective To analyze the efficacy and safety of Intra-arterial chemotherapy (IAC) as secondly treatment in children with retinoblastoma (RB). Methods 42 eyes of 34 consecutive RB patients were enrolled in the study after intravenous chemotherapy (IVC), including 26 males and 8 females. The average age is 14.1 months. 21 cases were bilateral and 7 cases were unilateral. A total of 42 eyes of 34 patients were classified according to the International Intraocular Retinoblastoma Classification（IIRC）as group B(n=1, 2.4%), group C (n=3, 7.1%), group D (n=32, 76.2%), or group E (n=6, 14.3%). Tumor recurrence and tumor enlargement after IVC were 4 and 10 eyes respectively, accounting for 9.0% and 24.0% respectively. Sequential treatment after IVC followed by IAC were 28 eyes, accounting for 67.0%. All treatment eyes received IAC combined with laser, cryotherapy and other eye local treatment. The IAC regimen adopted the combination and alternation administration mode, by the combination of melphalan and carboplatin or the combination of melphalan and topotecan. According to the tumor changes after IAC decide whether IAC again. If tumors increased, vitreous or subretinal implants increased will be termination of IAC and enucleation. The mean follow-up time was (21.4±3.7) months after the last IAC treatment and (6.2±2.9) months after enucleation. Ocular preservation rate and complication were evaluated. Results The average IAC procedures performed on 42 eyes were (4.0±0.9). An overall ocular preservation rate of 76.2% was observed during follow-up periods due to calcification or inactivation of tumors (32 eyes), including group B (n=1, 100%), group C (n=1, 33.3%), group D (n=27, 84.4%), group E (n=3, 50%). 10 eyes were enucleated. Among them, 2 eyes of the tumor did not shrink after IAC, tumor recurrence (n=3), vitreous hemorrhage (n=3), enophthalmos (n=1), vitreous disseminated (n=1). 34 cases of children, transient eyelid oedema were 18 cases, vitreous hemorrhage and bone marrow suppression (Ⅰ-Ⅳ) were 1, 22 casese respectively. Conclusions IAC as secondly treatment is safe and effective for RB patients, however, there is still tumor recurrence. No serious ocular local and systemic complications were observed.
