Macular hole (MH) formation after vitrectomy is rare and it may be due to several mechanisms associated with change of foveolar anatomy by vitrectomy. If a MH develops after vitrectomy, surgical treatments including internal limiting membrane peeling and intravitreal gas injection are usually needed for repair of hole. Spontaneous closure of MH is much rarer. ⋯ MH formation and spontaneous closure occurred in association with BRVO accompanying CME in a patient who had a vitrectomy. In vitrectomized eyes, physicians should consider the possibility of MH development in association with BRVO, and possible spontaneous closure of the MH in accordance with CME resolution.

The purpose of this study was to acquire the epidemic trend of age-standardized reported incidence and to analyze the age effect, period effect, and cohort effect on the reported incidence of hepatitis C in Jilin Province, China. We collected the annual reported incidence data of hepatitis C by gender (2008-2017). Annual percentage change and annual average percentage change were calculated by joinpoint Poisson regression analysis. ⋯ The birth cohort of the patients with the lowest incidence was in the 1980s, followed by the 1970s and 1960s. Although the overall reported incidence trend of hepatitis C is declining and the risk of the young birth cohort is low, many factors affecting infection and testing with hepatitis C still exist in China. We should focus on high-risk population management and formulate corresponding public health strategies to accelerate the implementation of the global health strategy to eliminate hepatitis C published by the World Health Organization.

Observational Study
"Sclerotic Band" type of classification system and measurement of necrotic area for osteonecrosis of the femoral head.
Osteonecrosis of the femoral head is a common orthopedic disease. Based on years of clinical experience and significant imaging data, this study aimed to elucidate a new type of it, to help improve prognosis in young adults and provide a basis for hip preservation treatment. From January 2014 to December 2016, a total of 211 patients undergoing hip preservation surgery for femoral head necrosis at our hospital were enrolled in this study. ⋯ After analysis, it is more accurate than JIC. The "Sclerotic band" type of classification system and 'quartile' methods are new methods to evaluate the stability of femoral head necrosis. They are convenient for clinical application and easily adopted.

This retrospective study was aimed to determine the factors suggesting the need for computed tomography (CT) scanning when ultrasound (US) imaging results are negative or non-diagnostic in children suspicious for acute appendicitis in the emergency department. Patients less than 18 years old who underwent abdominal ultrasound and CT to rule out acute appendicitis were enrolled. Patients were classified into 2 groups: the false-negative group, in which patients had negative or non-diagnostic results on the initial US and a final diagnosis of acute appendicitis on the following abdominal CT, and the true-negative group, in which patients had negative or non-diagnostic US results and were negative on abdominal CT. ⋯ The presence of vomiting (odds ratio (OR), 7.78; 95% confidence interval (CI), 1.92-41.04) and poor oral intake (OR, 4.67; 95% CI, 1.21-21.15) with a high white blood cell (WBC) count (OR 1.26; 95% CI, 1.09-2.37), segmented neutrophil ratio (OR, 1.09; 95% CI, 1.03-1.16), and C-reactive protein (CRP) (OR, 1.49; 95% CI, 1.09-2.37) were suggestive of the false-negative group. The propensity-matched population also showed significant associations with vomiting (OR, 7.86; 95% CI, 1.65-37.40) and poor oral intake (OR, 5.50; 95% CI, 1.28-23.69) with an elevated WBC count (OR, 1.27; 95% CI, 1.08-1.50), segmented neutrophil ratio (OR, 1.09; 95% CI, 1.03-1.16), and CRP (OR, 1.51; 95% CI, 1.03-2.22). A CT scan should be considered in children with suspected acute appendicitis if they have vomiting, high CRP, and high WBC count, despite negative or non-diagnostic US results.

Observational Study
Sexual dream and family relationships in frequent sexual dreamers and healthy volunteers.
Early life family relationships affect the sexuality in adulthood, and these influences might be reflected in sexual dreams. The present study was designed to investigate the exact associations between family relationships and sexual dream experience. We therefore invited 62 frequent sexual dreamers (dreamers) and 104 healthy volunteers (controls) to answer the Sexual Dream Experience Questionnaire (SDEQ) and the Family Relationship Questionnaire (FRQ). ⋯ In conclusion, there were pronounced associations between sexual dreams and family relationships in frequent sexual dreamers. Paternal Abuse in particular was associated with sexual dream experience. Adverse family relationships might induce frequent sexual dream occurrence, and family therapy or early intervention of Paternal Abuse might alleviate the negative sexual dream experience.
