Perfluoroalkyl substances (PFASs) are non-aromatic organic compounds, whose hydrogen atoms in the carbon chain substituted by fluorine atoms. PFASs exhibit developmental toxicity, carcinogenicity, hepatotoxicity, reproductive toxicity, immunotoxicity, and hormone toxicity. PFASs are used in the production of disposable food packages, aircraft and automobile devices, cooking utensils, outdoor gear, furniture and carpets, aqueous film forming foam (AFFF), cables and wires, electronics, and semiconductors. This study aimed to determine the association between crustacean consumption and serum PFASs.

Transvaginal cervical cerclage for the prevention of pregnancy loss in patients with cervical incompetence is well accepted. However, there is a small subject of patients with incompetence of cervix, congenital or surgical shortening of the cervix, previously failed transvaginal cerclage and deep cervical damage or tears in the fornices. We experienced a case of the transabdominal cervical cerclage. 'Ihe patient had a past history of deep cervical laceration due to vaginal delivery. Therefore, we present here a surgical technique of transabdominal cerdage and report it with brief review of literatures.

Benzophenone-3 is a type of ketone with 2 benzene rings attached to a carbonyl group (C=O) and one benzene ring attached to a hydroxyl group (-OH). As an endocrine-disrupting chemical, benzophenone-3 is known to be associated with reproductive, developmental, thyroid, and endocrine toxicities. Benzophenone-3 is commonly used in hair products, cosmetics, and ultraviolet (UV) filters because of its characteristic property to absorb UV light. This study aims to investigate the association between the use of hair products and urine benzophenone-3 using the data from the Korean National Environmental Health Survey (KoNEHS) cycle 4 (2018–2020), which represents the Korean population.

Results of vitrectomy as treatment of full thickness(stage 3,4) macular hole were reported large variability and difference n anatomical and funtional success rate. So many surgeons fely difficulty in expectation of postoperative results before operation on stage 3,4. To use decision of proper operation time & effective treatment and expect the postoperative results before operation, after anatomical & functional factor affecting postoperative results & prognosis were arranged, relationship of these data after vitrectomy were evaluated. Pars plana vitrectomy in 25 patients(25 eyes) with stage 3(8 eyes) and stage 4(17 eyes) macular hole was performed. Functional success was seen in 7 eye(28%) and Anatomical success was seen in 12 eyes(48%). Preoperative factors such an stage of macular hole, preoperative visual acuity, size or macular hole, and sex were not found any association with postoperative functional & anatomical success rate. the group that had completely attached hole after vitrectomy and small preoperative cuff size(<1.0mm) were showed improvement of visual acuity compared with the other group. But these results were statistically not significant. And patients (5 eyes) with additional removal of ILM with PVD or memb peeling were showed good anatomical success rate(80%), but no difference of postoperative visual acuity compared with the other group. Although preoperative fluid cuff size and around hole and completely closure of hole after surgery were statistically not significant, highly correlated with postoperative visual acuity compared with the other factor. But long-term follow-up & recruitment of additional cases are required to consider as one of the significant factor on deciding operation time & expecting postoperative result.
