The purpose of this study was to evaluate body dissatisfaction, eating attitudes, and exercise behavior in female adolescents and to develop strategic countermeasures against those epidemic phenomenon. A total of 269 junior female high school students participated in this study, and were divided into three groups based on the body mass index (BMI); BMI<18.5: underweight (UW), 18.5-24.9: average weight (AW), and 25.0-29.9 overweight (OW), A questionnaire consisted of Body Dissatisfaction Index (BD[), Eating Attitude Test-26 (EAT26), Obesity Related Stress (ORS), and exercise behavior was administered, For the comparisons of means, one-way ANOVA was employed, and relationships between variables were assessed by correlation coefficient, For the analyses of relationship between BDI and EAT26, and physical activities, X² was utilized, The BD[ between UW and OW was significantly different (P<.05) while no differences were found in EAT26 among groups. ANOVA revealed ORS score was statistically different (P<.05), but post-hoc test did riot show any differences among groups, In each group, BMI and EAT26, and BMI and BDI were highly correlated (P<.05). However no relationships were found between BDI and EAT26. When comparing the level of physical activities among groups, no differences were found. The prevalence or inactive (less then average) was 24.7, 28.9, and 45.2% in UW, AW, and OW, respectively. The desire for exercise was 94.6, 94.5, and 100% in UW, AW, arid OW, respectively, and this was statistically different (P<.05), The perception or exercise necessity was highly rated in all groups, particularly in OW female adolescents.

Blunt or nonpenetrating chest injuries are common after motor vehicle accidents or falls. Blunt injury to the heart ranges from contusion to rupture. Cardiac rupture, however, is un-common and associated with a very high mortality rate ; left ventricular rupture due to falling is even more rare. We experienced a case of left ventricular rupture of the heart caused by a fall, which the patient survived. A 63-year-old man fell off a ladder and presented with hypotension from left hemothorax and pericardial tamponade. The hemothorax was relieved via an emergency closed thoracostomy but dyspnea and hypotension continued. And so, echocardio-graphy was done and pericardial tamponade was detected. Emergency left thoracotomy was done to repair the rupture site. We believe that patients with cardiac rupture who reach the hospital alive can often be saved by prompt diagnosis and immediate surgical treatment.

Root canal preparation process is of utmost importance in successful treatment of root canal. Also, one of the most important purpose of the root canal preparation is to enlarge the root canal three dimensionally without changing the curvature of the root canal. However, as the curvature of the root canal increases, there are many difficulties involved in formation of optimum root canal. Therefore, in order to solve the above mentioned problems, new developments in methods of root canal preparation and equipments for such purposes were made. Recently, vigorous studies about newly introduced engine-driven nitckel-ti-tanium rotary file are conducted. As shown in research results to dates, it is well established that the use of nickel-titanium file is better suited for curved root canal than stainless steel file in maintaining the curvature of root canal and reducing the deformation of root canal. However, it is also acknowledged that there are a few discrepancies in research results according to protocol, due to failure to remove variables in experiments. In addition, although it is recommended by the manufacturer that the GT rotary file should maintain a low rotational speed of 150∼350rpm and 'light pressure' as light as not to break the lead of a pencil, academic studies about the vertical force which is not yet standardized are not sufficiently explored. Therefore, this research devised and utilized a special research equipment to standardize the appropriate range of vertical force for GT rotary file through experiments by breaking of the lead of a pencil as expressed by the manufacturer and to accurately measure factors involved through repeating and recreating the environment of root canal preparation. Forming nine experimental groups by varying the vertical forces (150g, 220g, 300g) and rpm (150rpm, 250rpm, 350rpm), the effects of changing vertical forces and rpm on working efficiency were measured in terms of time expended in root canal preparation by crown-down method using a transparent resin block with 35 degree curvature and GT rotary file (z-test). The following research using this special research equipment that involved nine experimental groups and varying the vertical force for root canal preparation from 300g which is within the normal vertical force range to 700g and 1000g which fall outside the normal rpm range. The results were as follows : 1.Analysis of the experiment results revealed that the tome spent in root canal preparation decreased as the vertical forces and rpm increased (p<0.05). Also, the effects of rpm were greater than those of the vertical forces within the normal vertical force range (β-weight test) . 2.Observation of the deformation of GT rotary file revealed that deformation increases in a direct correlation with the vertical force increase and in a reverse correlation with the rpm decrease, In the case of the vertical forces close to the normal range, the probability of GT rotary file deformation were quite different depending on the rpm changes. In the case of◎eater tier◎cal forces, the occurrences of deformation of the file were more frequent regardless of the rpm changes. 3.Deformation and breakage of file were also commonly observed in the expended time measurement experiments and GT rotary file deformation experiments in which low speed rpm (150rpm) was used and at the curved portion of the resin block. Key words : GT rotary file, Crown-down method, Working efficiency, Vertical force, Rpm, Deformation and breakage of file

Spitzoid melanocytic lesions may be broadly categorized into Spitz nevi, Atypical Spitz tumor(AST)s, and spitzoid melanomas. Atypical Spitz nevus have overlapping features of both Spitz nevi and Spitzoid melanoma, and consequently, generate controversies with diagnosis and management. A 19-year-old male patient presented with dome-shaped, erythematous nodule on the posterior side of right thigh. The lesion was first recognized a month ago and there was no accompanying symptoms. On physical examination, the papule was 6mm in diameter with symmetric, and no ulcer. Laboratory tests were not performed, and family history was unspecified. Histologically, the lesion shows well circumscribed tumor nest from the dermo-epidermal junction to the reticular dermis with a few epidermal pagetoid spread. The nest composed of large epithelioid cells with prominent nucleoli. Each cells showed uniform pleomorphism and some had mitosis. Kamino bodies were observed, and closer inspection revealed incomplete maturation of nest in the deeper portion. Immunohistochemical study revealed positive of HMB-45, Ki index of 10-20 %, and sentinel lymph node biopsy was negative. The diagnosis of atypical Spitz tumor with lower risk of metastasis was made because of but not enough to consider a diagnosis of melanoma. The tumor was removed by total excisions. No recurrences or metastases were detected during the follow-up period of 6 months.

Molluscum contagiosum(MC) is a viral infection that causes multiple flesh colored papules on the skin and mucous membrane. MC is caused by poxvirus affecting children, sexually active adults, and immunocompromised individuals. Children frequently develop MC lesions on the trunk, arms, and face. The nipple or areola is the site of some dermatoses, the commonest cause being Paget``s disease. Other cause are nevoid areolar hyperkeratosis, several skin neoplasm and also including infectious ones, such as warts. MC lesions in this uncommon localization can be confused with each of these diseases. We are presenting the case of a 3-year-old girl with a solitary flesh-colored papule on her right areola for almost a year without marked size variation. The lesion was neither pruritic nor painful. Clinically we suspected nevoid hyperkeratosis of areola and did punch to confirm. Histologically showed multiple molluscum bodies and we could make diagnosis of MC. This case is very rare as the isolated nipple or areola is an unusual site of presentation for MC. Herein, we report a rare case of solitary MC on the areola.

A case of psoriasiform drug eruption caused by adalimumab and ustekinumab

Cutaneous adverse effects of TNFα inhibitors are probably more common than previously suspected. A 64-year-old male patient with psoriasis lasting for 40 years had started adalimumab, TNFα inhibitor treatment. One week after the induction dose injection, erythematous patch that different from the existing psoriatic lesions developed on the legs. The lower part of the neck also had a new erythematous lesion. The newly developed lesions were accompanied by less scale and mild pruritus. The skin biopsy specimen showed psoriasiform epidermal hyperplasia with hyperkeratosis and parakeratosis. There were telangiectasia in the papillary dermis associated with a perivascular lymphocytic infiltration. The skin lesion improved as the adalimumab was stopped, but recurred as ustekinumab, anti-IL12/23 antibody. After switching to guselkumab, anti-IL23 antibody, the lesions cleared completely with the psoriasis. It remains unknown why patients develop psoriasiform eruptions while on anti TNFα agents. One possible explanation involves increased IFNα activity with TNFα inhibition. This excess of IFNα can promote the activation of autoreactive T cells, and the predominantly lichenoid or spongiotic autoreactivity to keratinocytes might be mediated by the CD8+T cells. Also, Ustekinumab blocking Th1 inflammatory pathways(IL-12) might have partially acted as TNF-a inhibitor.

A case of recurrent herpes zoster after varicella-zoster vaccination (ZOSTAVAX®)

( Joo Yoon Bae ),( Hong Lim Kim ),( Hyun Yi Suh ),( Kyung Ho Kim ),( Ji Young Ahn ),( Mi Youn Park ),( Jai Il Youn ) 대한피부과학회 2016 대한피부과학회 학술발표대회집 Vol.68 No.1

Herpes zoster(HZ) can be caused by endogenous reactivation of both wild-type virus or vaccine varicella-zoster virus (VZV) becoming latent within sensory ganglia after natural primary infection or varicella vaccination. Reactivation of VZV is associated with age related or other causes of decreased T cell immunity. A concentrated live attenuated vaccine (ZOSTAVAX®) boosts this immunity and provides partial protection against HZ. A 73-year-old male patient visits our clinic for showing erythematous vesiculo papules on the right thigh and buttock. These leaions were accompanied by itching sensation without any pain. Two weeks prior to presentation, the patient got a VZV vaccination. The patient reported the medical history for a HZ 2 years ago. Laboratory result was non-specific, but Tzank smear result was positive. Biopsy showed inclusion body. We report a rare case of adverse effect of VZV vaccination, HZ resulting from replication of the vaccine virus in immunocompetent hosts.
