  • Comparison of yellow micro pulse photocoagulation and traditional laser grid photocoagulation for diabetic macular edema

    Objective To compare the clinical results of yellow micro-pulse laser and traditional laser grid (MLG) photocoagulation for diabetic macular edema (DME). Methods Seventy-eight patients (106 eyes) with DME diagnosed by fundus fluorescein angiography (FFA) and optical coherence tomography (OCT) were enrolled in this study. The patients were divided into micro-pulse group (39 patients, 51 eyes) and MLG group (39 patients, 55 eyes). The patients of micropulse group underwent 577 nm yellow micro-pulse laser therapy, while the patients of MLG group underwent continuous wavelength laser photocoagulation with a 561 nm yellow green laser. All the patients were examined documenting corrected visual acuity, macular retinal thickness (CMT) and mean sensitivity within macular 10 deg; examination before and after treatment. Six months after treatment was considered as the judgment time for the therapeutic effects. The mean corrected visual acuity, CMT and MS were comparatively analyzed. Results Six months after treatment, the mean corrected visual acuity of micropulse group and MLG group were 0.45plusmn;0.20 and 0.42plusmn;0.20, which increased significantly compared to those before treatment (t=3.404,2.316; P<0.05). The difference of mean corrected visual acuity between before and after treatment of micro-pulse group and MLG group were 0.08plusmn;0.02 and 0.06plusmn;0.03, the difference was statistically significant between two groups (t=0.532, P>0.05). The mean CMT of micropulse group and MLG group were (323.94plusmn;68.30) and (355.85plusmn;115.88) mu;m, which decreased significantly compared to those before treatment (t=4.028, 2.039; P<0.05). The difference of mean CMT between before and after treatment of micro-pulse group and MLG group were (55.12plusmn;13.68) and (22.25plusmn;10.92) mu;m. The difference was not statistically significant between two groups (t=1.891,P>0.05). The mean MS of micro-pulse group and MLG group were (6.63plusmn;2.65) and (4.53plusmn;1.81) dB. The mean MS of micro-pulse group increased significantly compared to that before treatment(t=3.335,P<0.05). The mean MS of MLG group decreased significantly compared to that before treatment (t=3.589,P<0.05). The difference of mean MS between before and after treatment of micro-pulse group and MLG group were (1.10plusmn;0.33) and (-0.91plusmn;0.25) dB.The difference was statistically significant between groups (t=4.872,P<0.05). Conclusions In the treatment of DME, yellow micro-pulse laser therapy and MLG can improve visual acuity, and reduce CMT. In addition, yellow micro-pulse laser therapy can improve the MS, but MLG reduces MS.

  • Effect of Puncture Methods on Ultrasound-guided Fine-needle Aspiration Biopsy of Thyroid Nodules

    ObjectiveTo assess the effect of short-axis and long-axis punctures of thyroid nodules on the diagnostic rate of ultrasound guided aspiration biopsy (US-FNAB). MethodsWe retrospectively analyzed the clinical data of 2 686 thyroid nodule patients who underwent US-FNAB between March 2011 and November 2014. The US-FNAB was performed by 5 beginners (571 each for Dr1-Dr4 and 402 for Dr5). Yields of US-FNAB were divided into two levels according to the classification standard of the Bethesda system:adequacy and inadequacy. Short-axis puncture technique was used by Dr2 and long-axis puncture was performed by the others. According to chronological sequence of thyroid nodules examined, we compared the inadequate diagnostic rate between Dr2 and the others for the first 200 cases and the last 200 cases, respectively. The inadequate diagnostic rate was compared among the 4 doctors who used long-axis punctures for the first 200 cases and the last 200 cases, respectively. ResultsThe inadequacy rate of US-FNAB for Dr2 was higher than that for Dr1, Dr3, Dr4 and Dr5 in the first 200 cases, with statistical significance (P=0.036,<0.001,=0.007 and <0.001, respectively). There was no significant difference in inadequate diagnostic rate among the 4 doctors who used long-axis punctures for the first 200 cases (P=0.033, 0.551, 0.011, 0.122, 0.672 and 0.050). The inadequacy rate of US-FNAB for Dr2 was higher than that for Dr5 and lower than that for Dr4 in the last 200 cases with statistical significance (P=0.027 and 0.003, respectively). The inadequacy rate of US-FNAB for Dr5 was lower than that for Dr3 (P=0.005) and Dr4 (P<0.001) among the 4 doctors who used long-axis punctures for the last 200 cases. ConclusionFor beginners, the inadequacy rate of short-axis puncture is higher than long-axis puncture. We suggest beginners learn long-axis puncture method. There is no significant difference in inadequate diagnostic rate among short-axis and long-axis punctures, when the number of operated cases reaches 200. At this point, the operator can choose either way to puncture according to the disease condition or personal interests.

  • The nursing cooperation in ultrasonography-guided core-needle biopsy of thyroid nodules

    Objective To discuss the nursing measures for thyroid nodule patients who undergo core-needle biopsy (CNB) guided by ultrasound. Methods We retrospectively analyzed the experiences and main points of nursing for 1 900 thyroid nodule patients who underwent CNB guided by ultrasound between June 2010 and May 2014. Results All the 1 900 patients underwent CNB successfully. The nursing time was between 5 and 15 minutes, averaging (8.0±3.7) minutes. Complications included hematoma in 25 patients (1.3%) and needle syncope reaction in 30 patients (1.6%), which were cured through symptomatic treatment. No complications such as nerve injury, anesthesia accident or death occurred. No medical disputes happened due to specimen errors or loss. The success rate of specimen collection was 98.4% (1 870/1 900), and the diagnostic accuracy was 95.3% (1 812/1 900). Conclusions Ultrasonography-guided CNB is a safe and reliable operation with a high success rate, high diagnosis accuracy and few complications. Being familiar with the process of nursing cooperation and correct disposal and transfer of biopsy specimens are crucial for successful CNB in patients with thyroid nodules.

  • Detection of retinal and optic disc neovascularization in patients with stage 4 diabetic retinopathy by multidirectional optical coherence tomography angiography

    ObjectiveTo observe and analyze the detection rate of optical disc and retinal neovascularization in stage Ⅳ diabetic retinopathy by multidirectional OCT angiography (OCTA).MethodsA retrospective study. From September to October 2018, 50 eyes of 46 patients with diabetic retinopathy of stage Ⅳ diagnosed in Tangshan Ophthalmological Hospital were included in the study. Among them, there were 18 males (19 eyes) and 28 females (31 eyes). The age ranged from 31 to 78 years, with an average age of 56.64±10.64 years. All patients underwent medical optometry, mydriasis fundus examination and FFA examination. All patients met the diagnostic criteria of stage Ⅳ diabetic retinopathy. All patients underwent multidirectional OCTA examination on the same day after mydriasis fundus examination and FFA examination. Angiography 6 mm × 6 mm scanning mode was selected for OCTA examination. The retinal areas of macular area, optic disc, superior nasal disc, superior optic disc, superior macular area, superior temporal macular area, temporal macular area, inferior nasal disc, inferior optic disc, inferior macular area and inferior temporal macular area were scanned respectively. All images were taken by the same physician and read by two physicians independently. Cases with inconsistent opinions between the two physicians were not included in this study. The optical disc and retinal neovascularization in patients with stage Ⅳ diabetic retinopathy were observed on FFA and multidirectional OCTA images.ResultsIn 50 eyes, the positive number of screening optic disc neovascularization using FFA was 8 eyes, OCTA was 15 eyes (100%). In the 42 eyes without optic disc neovascularization detected by FFA, OCTA detected 7 eyes, all located on the optic disc surface. Four of the eyes were located in the optic cup, linear and branching, with an area of less than 1/4 optic disc. In 50 eyes, the positive number of screening retinal neovascularization using FFA was 50 eyes, the positive number of OCTA was 43 eyes. In 43 eyes with detected by OCTA, retinal neovascularization buds were detected in 3 eyes, but not in FFA. The retinal neovascularization not detected by OCTA was located in the mid-peripheral part of the retina, which is beyond the inspection range of multi-directional OCTA.ConclusionThe positive rate of optic disc neovascularization and retinal neovascularization in stage Ⅳ DR by multidirectional OCTA is 100.0% and 86.0%, respectively.
