METHODS A retrospective study was conducted first and then a validation set was used to investigate the value of an HSST sign in predicting biliary atresia (BA). In the retrospective study, laparoscopic images of the liver surface were reviewed in 126 patients with infantile cholestasis (72 BA patients and 54 non-BA cholestasis patients) and a control group of 38 patients with nonhepatic conditions. Analysis was first made by two observers separately and finally, a consensus conclusion was achieved. Then, the diagnostic value of the HSST sign was validated in an independent cohort including 45 BA and 45 non-BA patients. RESULTS In the retrospective investigation, an ampli.ed HSST sign was found in all BA patients, while we were unable to detect the HSST sign in 98.1% of the 54 non-BA patients. There was no HSST sign in any of the control subjects. In the first review, the sensitivity and specificity from one reviewer were 100% and 98.1%, respectively, and the results from the other reviewer were both 100%. The consensus sensitivity and specificity were 100% and 98.1%, respectively. The HSST sign was defined as being composed of several enlarged tortuous spider-like vascular plexuses with two to eight branches distributed on all over the liver surface, which presented as either a concentrated type or a dispersed type. In the independent validation group, the sensitivity, specificity, positive predictive value and negative predictive value of the HSST sign were 100%, 97.8%, 97.8% and 100%, respectively. CONCLUSION The HSST sign is characteristic in BA, and laparoscopic exploration for the HSST sign is valuable in the diagnosis of BA.展开更多

SN are treated via different techniques, and complete removal often requires multiple treatments. However, few studies have evaluated the treatment of SN. The present study aimed to evaluate the therapeutic effect and safety of a 595-nm pulsed-dye laser (PDL) for treating facial SN in children.Methods:A total of 110 children aged 0.2 to 12 years with facial SN were treated with a 595-nm PDL in a single institution from January 2016 to February 2018. In accordance with the treatment method, the patients were retrospectively divided into the small-spot-combined-with-large-spot group (SL-group) and the large-spot group (L-group). Patients with poor therapeutic results were retreated every 6 weeks until the lesions disappeared. The minimum follow-up period was 1 year. The groups were compared using independent-samples t tests, Mann-Whitney U test, Chi-square test, and Fisher exact probability test.Results:The therapeutic efficacy was significantly higher in the SL-group than in the L-group, with clearance rates of 90.9% and 53.0% after the primary treatment, respectively (χ2= 17.937, P < 0.001). For skin lesions with a central spider body diameter ≥1 mm, the once-treatment cure rates were 100% in the SL-group and 34.8% in the L-group (χ2 = 20.780, P < 0.001). For skin lesions with a central spider body diameter <1 mm, the once-treatment cure rates were 82.6% in the SL-group and 62.8% in the L-group (χ2 = 3.961, P = 0.138). The rates of adverse reactions and recurrence did not differ between the two groups (P = 0.141 and P = 1.000, respectively).Conclusions:The 595-nm PDL might be a safe and effective treatment option for facial SN in children. The small-spot-combined-with-large-spot method is especially suitable for SN with a central spider body diameter ≥1 mm.展开更多

Best-corrected visual acuity(BCVA) measurements, noncontact tonometry, ophthalmoscopy, fundusphotography, fundus fluorescein angiography and optical coherence tomographywere performed before treatment and at 1 wk, 1 mo, 3 mo, 6 mo, 9 mo, 12 mo, 24mo and 36 mo after therapy. Best-corrected visual acuity was measured using theearly treatment of diabetic retinopathy study chart.RESULTS The study included eight eyes of 8 patients (7 men) aged 36.10 ± 6.65 years. Theaverage BCVA of the affected eye before treatment was 51.17 ± 15.15 letters(range, 28–70 letters), and the average central macular thickness was 303.30 ±107.87 μm (range, 221–673 μm). Four eyes were injected once, three were injectedtwice, and one was injected three times. Average follow-up duration was 37.33 ±2.26 mo. Average BCVA of the affected eye was 51.17 ± 15.15 letters before treatment and was increased by 13.50 ± 3.20, 16.25 ± 7.73, 18.25 ± 8.96, 18.03 ± 5.27,18.63 ± 3.35, 19.75 ± 6.96, 18.05 ± 5.36 and 17.88 ± 3.45 letters at 1 wk, 1 mo, 3 mo, 6mo, 9 mo, 12 mo, 24 mo and 36 mo after treatment, respectively (P < 0.01). Thepatients showed varying degrees of subretinal fluid resorption after treatment.None of the patients had serious complications such as increased intraocularpressure, development/progression of cataracts, endophthalmitis or retinaldetachment.CONCLUSION Intravitreal injection of conbercept combined with 532-nm laser photocoagulationmay be a feasible treatment for Coats disease in adul展开更多
