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.

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.

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

X-linked recessive ichthyosis (XLRI) is an inherited disorder of keratinization due to steroid sulfatase deficiency, occurs only in men. There is no case report for the coexisting of XLRI and psoriasis, and association of two diseases is unknown. A 50-year-old man was being treated for psoriasis and XLRI. Onset of psoriasis was 30 years ago, and XLRI was reported to occur immediately after birth. The patient’s uncle on mother's side al so had XLRI. The patient had no family history of psoriasis and other medical history. He had psoriasis lesions of scaly erythematous plaque and ichthyosis lesions of fine scale patches on the whole body. Psoriasis and ichthyosis were treated with conventional treatment, but they did not show effect and wax and wane. Ustekinumab was started to treat psoriasis two years ago. With the start of Ustekinumab, psoriasis as well as ichthyosis lesions improved. When the patient was scheduled to take the fifth injection, he visited the clinic one month later than scheduled date, both the psoriasis and ichthyosis lesions were worsened again. Re-administration of Ustekinumab improved both disease lesions. Here in, we report a case of psoriasis associated with XLRI as an interesting case of improvement of both diseases in Ustekinumab treatment.

Primary inoculation tuberculosis results from the direct inoculation of Mycobacterium tuberculosis into the skin of a person who has no natural or artificially acquired immunity to the organism. The Cutaneous TB is rarely seen and accounts for only a small proportion (<1-2 %) of all TB cases. The pathogenesis requires a break in the skin due to an abrasion or injury, which allows entry of the tubercle. A 42-year-old male surgeon suffered a needle stick injury to the lateral aspect of the interphalangeal joint of the thumb of the left hand while performing a incision and drainage procedure for tuberculous arthritis of hip joint. After 4 weeks, urcerated nodule on the injured finger site persisted without lesional and systemic symptoms. Histopathologic findings showed granulomatous inflammatory infiltration and acid-fast bacilli. M. tuberculosis was identified by polymerase chain reaction. He was treated with rifampicin, isoniazid, pyrazinamide, and ethambutol for 6 months. Health care workers are at risk of direct inoculation of tuberculosis. In the case described here, an exogenous source of infection was evident, and the clinical characteristics indicated that the lesion was a primary inoculation tuberculosis. We report a typical case of primary inoculation tuberculosis, which is rarely observed.

Hobnail hemangioma is a vascular tumor affecting the limbs or trunk. Characteristically, the lesion has a “targetoid” clinical feature and dilated vascular spaces lined by hobnail endothelial cells at histologic examination. We report a case of trauma-induced hobnail hemangioma with atypical appearance. A 79-year-old female visited our clinic for erythematous papules and with excoriation on her right thigh. The skin lesions developed the 2 years ago and were treated by topical steroid. From 14 days ago, the erythematous patches and pruritus aggravated. At first, we diagnosed clinically as prurigo nodularis. We implemented punch biopsy and it histologically showed compact hyperkeratosis, epidermal hyperplasia in epidermis and many dilated lumens in upper dermis. Ectatic vessels and proliferation of endothelial cells that were stained for CD 31, CD 34, Factor 8 witch was appropriate to hobnail hemangioma. The patient has clinical features of prurigo nodularis, but histopathological findings was hobnail hemangioma. We consider that hobnail hemangioma induced by trauma, such as excoriation, and report this impressive case.

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.
