BACKGROUND: Correction of a bulbous tip is a difficult procedure in Asians, because their lower lateral cartilage is relatively small and structurally weak to support the thick skin soft tissue envelope (SSTE). Therefore, lower lateral cartilage manipulation alone yields inadequate bulbous tip correction. In this study, authors aim to provide a new bulbous tip definition reflecting nasal tip SSTE and categorization with a suitable surgical procedure. METHODS: One hundred sixty-three patients with tip rhinoplasty between January 2009 and December 2012 were studied who had a tip lobular width greater than 60% of the alar base width. Depending on cartilage size and characteristics of the nasal tip superficial musculoaponeurotic system (SMAS) with SSTE thickness, the following classifications were made: Group I: thin SSTE with a large lower lateral cartilage, Group II: thick SSTE with a small lower lateral cartilage, Group IIa: thick SSTE with loose SMAS, and Group IIb: thick SSTE with dense SMAS. We evaluated the degree of surgical improvement by comparing pre- and postoperative photographs. RESULTS: After comparing pre- and postoperative photos, we observed improvements in tip bulbosity by 11.7% in Group I (n=41), 11.9% in Group IIa (n=64), and 7.1% in Group IIb (n=58). CONCLUSIONS: In Asians, nasal tip bulbosity is often due to excess SSTE. Therefore, a bulbous tip should be defined and evaluated based on its underlying SSTE. Adequate soft tissue resection in addition to lower lateral cartilage support and manipulation are warranted to achieve a refined tip.

Congenital adrenal hyperplasia (CAH) during pregnancy is a rare condition. Only a few cases have been reported in the literature. CAH patients has lower pregnancy rate compared to normal women. A 27-year-old nulliparous woman, a diagnosed case of 21-hydroxylase deficient simple virilising form of classic CAH visited. She got pregnant spontaneously without any trial of assisted reproductive technology. At the age of 12, she underwent clitoral resection and vaginoplasty. She took dexamethasone or prednisolone after operation. She delivered healthy singleton female baby by cesarean section. Four years later, she delivered healthy singleton female baby by repeat cesarean section. Two female babies have shown normal external genitalia. Here, we report a case of successful pregnancy and delivery in a patient with CAH.

Anatomy is an essential subject for dental hygienists. As such, in order to form academic systems for dental hygiene program, we cannot ignore research related to basic dental hygiene, which is related to the main competency of a dental hygienist. This research focused on the operation status of the curriculum related to gross anatomy of the head and neck led by the department of dental hygiene and was performed in order to propose a new direction regarding academics. This research analyzed the offering status of the anatomy curriculum using shared information, released by both the Association of Korean Dental Hygienist and the homepage website of the national dental hygiene, as a foundation. In addition, we conducted a survey of 21 (25.6%) professors out of 82 dental hygiene institutions in the nation. The fill-in survey was composed in order to obtain knowledge on each department's offering and operation system of the anatomy curriculum, general characteristics of professor and demand for the anatomy education. The SPSS 20.0 Program was used to analyze all of the materials with the exception of operation statuses of anatomic curriculums constructed via open questions. Nationally, the subject related to the gross anatomy was opened in Semester 2 during the first year 56.2% of the time, and the oral anatomy class recorded the highest percentage of 45.3%. The general trend of the professors who participated in this research was the highest recording of 85.0% for holders of dental hygiene license. Those who acquired doctoral degrees were found to be 17 individuals (85.0%) and 45.0% majored in health science. The operation methods of anatomic practices were revealed to be models, drawings, and audiovisuals while external practices failed to meet even the half-point of the study. The consensus opinion has indicated the need for a integrated education with clinical subjects, cadaver practices, developments of educational media, and standardization of anatomic terminology. Standardization of educational contents and systemization of practices are necessary for the improvement of anatomic studies of students studying dental hygiene. Cultivating anatomy specialists and sharing activities between academia are required for long-term development. We expect this research to contribute to overall quality improvement and the dental hygiene profession through the establishment of majors.

OBJECTIVE: A meta-analysis was performed to determine effect of ginseng on blood pressure. METHODS: The databases of PubMed, Embase, Cochrane Library, RISS, DBpia, KISS, and Koreamed were searched for all published studies from inception to January 2016. The following terms were used: "ginseng", "hypertension", and "blood pressure". Using the Review Manager 5, mean differences (MDs) were pooled to measure the effect of ginseng on blood pressure compared to that of placebo. RESULTS: Eleven randomized controlled trials were included. In this meta-analysis, ginseng treatment significantly lowered systolic blood pressure (SBP) in a dose-independent way (MD: -1.99, p = 0.04). In subgroup analysis, 8-12 week consumption of ginseng achieved significantly greater reduction in SBP (MD: -3.14, p = 0.03), while single administration of ginseng failed to show BP-lowering effect. When ingested over 8-12 weeks, ginseng significantly lowered diastolic blood pressure (DBP) (MD: -1.96, p = 0.03). No significant association was found between ginseng dose and the magnitude of BP-lowering effect. However, a significant positive relationship was observed between baseline SBP level and the magnitude of SBP reduction (r = 0.848, p = 0.033). Such a relationship was not seen in DBP. CONCLUSION: Consumption of ginseng for 8-12 weeks achieved significant reductions in SBP and DBP in a dose-independent way. There was a significant positive relationship between baseline SBP level and the magnitude of SBP reduction.

PURPOSE: To analyze the clinical effectiveness of tafluprost used in the treatment of glaucoma, using ocular pulse amplitude (OPA) measurements with dynamic contour tonometry (DCT). METHODS: Sixty patients (119 eyes) with normal tension glaucoma (NTG) or primary open angle glaucoma (POAG) treated with tafluprost or other eyedrops were investigated in the present study. Intraocular pressure (IOP) was measured with Goldmann applanation tonometry (GAT), and OPA was measured with DCT, before and after treatment, retrospectively. RESULTS: In 20 patients treated with tafluprost, IOP decreased from 17.1 mm Hg before treatment to 13.0 mm Hg 3 months after treatment (24.0% descent rate), and OPA decreased from 2.35 to 1.57 (33.2% descent rate). For 20 patients who switched from another monotherapy to tafluprost, IOP decreased from 15.7 mm Hg to 13.2 mm Hg from 15.7 mm Hg (15.3%) and OPA from 2.38 to 1.69 (27.7%). CONCLUSIONS: Tafluprost used to treat glaucoma has a large OPA and IOP lowering effect and, therefore can be applied to patients who have a large OPA with glaucoma progression in spite of well controlled IOP.

Several studies showed that the inflammatory and fibrotic responses induced by polyhexamethylene guanidine phosphate (PHMG-p) were similar to those observed for idiopathic pulmonary fibrosis in South Korea in 2011. “Omic” technologies can be used to understand the mechanisms underlying chemical-induced diseases. Studies to determine the toxicity of chemicals may facilitate understanding of the mechanisms underlying the development of pulmonary fibrosis at a molecular level; thus, such studies may provide information about the toxic characteristics of various substances. In this review, we have outlined the cellular and molecular mechanisms underlying idiopathic pulmonary fibrosis and described pulmonary fibrosis induced by various chemicals, including bleomycin, paraquat, and PHMG-p, based on the results of studies performed to date.
