Continued improvements in treatments of the thoracolumber spine have occured in the last several years. The operative treatment of choice currently is short segment fusion(instrumentation one level above to one level below the injury). The development of pedicle screw systems has brought short segment fusion into clinical reality from the posterior approach. We analysed the clinical results of 20 patients with unstable fracture and fracture-dislocation of thoracolumbar spine who were treated with the posterior transpedicular screw system. The mean fol- low-up was 18 month. Ll was the most common injury level and the bursting fracture was the most common fracure type by Denis classification. The mean preoperative sagital index was 21.5。 and improved 8.1。 postoperatively. The mean preoperative anterior and posterior height of the vertebral height were 56.9% and 88.8% and improved postoperatively 94.7 and 88.8 respectively. The mean preoperative neural canal impingement in neural defici: patient was 47.2% and was improved 30.65% postoperatively. The mean prooperative ASIA motor was 34.1 and improved 41.7 postoperatively. There was no metal failure. These data suggested that the posterior transpedicular screw fixation, transpedicle bone graft, decompression and posterolateral bone graft was able to porvide sufficient stability and to achieve the neurologic improvement.

PURPOSE: TGF-beta is a key regulator of epithelial-mesenchymal transition. Among the TGF-beta responses, cell migration is closely associated with the expression of matrix metalloproteinases (MMPs). Therefore, we determined which MMPs are regulated by TGF-beta and examined the TGF-beta signaling involved in this event, focusing on Src family tyrosine kinases (SFKs) METHODS: First we examined the expression of MMPs in rat lens explant culture treated with TGF-beta and LECs attached to the anterior capsules of patients with nuclear (N), anterior polar (AP) cataracts using RT-PCR and immunofluorescence staining. It was examined whether the expression of MMPs is regulated by SFKs. RESULTS: The study using RT-PCR and immunofluorescence staining showed the expression of MMP-2 and -14 in explants and the expression of MMP-14 LECs of AP cataracts. The expression of MMP-2 and -14 was blocked by PP2 in explants. Furthermore, the activated form of SFKs was observed in LECs of AP cataracts by immunofluorescence staining. CONCLUSIONS: We suggest a novel role of SFKs signaling in the expression of MMP-14 induced by TGF-beta.

There are many procedures for treatment of injuries of acromioclavicular separation but there are still con- roversies concerning the best management of these injuries. With this in mind, we treated surgically 22 cases of acromioclavicular separation of which 3 cases were old type 2 and 19 cases were type 3 in the department of orthopaedic surgery, Eul Ji General Hospital from March 1977 to darch 1982. The results were as follows: l. Of 22 cases, 21 cases (95.5%) were male with peak incidence in the 3rd and 5th decades (90.9%). 2. The most common causes of the injuries were traffic accidents (63.6%) and followed by falling from height (22.7%). 3. The diagnosis in type 2 and type 3 injuries is based on the clavicular displacement and instability at the acromioclavicular joint. 4. Operative treatment consists of Weaver and Dunn method (54.5%), modified Phemister method (18.2%), Neviaser method (13.0%), Stewart method (9.1%) and modified Henry method (4.5%). 5. The operative procedure in old type 2 and typc 3 injuries is good treatment of acromioclavicular separation.

Excess hair growth in unwanted areas may result from heredity, endocrine disease, or drug therapy. Conventional methods of hair removal include shaving, wax epilation and chemical depilatories that frequently cause side effects such as contact dermatitis and that also have temporary effects. Electrolysis is a well-established medical method for permanent destruction of terminal hair follicles. However, this method is tedious and efficacy has been reported to range from 15-to-50% permanent hair loss. The evolution of the laser use for hair removal continues a year after Food and Drug Administration (FDA) approval of the first laser for these applications. The authors have experienced hair removal utilizing a long-pulsed alexandrite laser. This laser system employs the principle of thermokinetic selectivity, a revolutionary concept. The principle of thermokinetic selectivity involves the use of lasers with pulse durations below the thermal relaxation on a the large target such as the hair folllicle (40-100 msec), and significantly longer than the thermal relaxation time of smaller structures of the same chromophore (melanin) in epidermis (3-10 msec). The study was based on 76 patients treated with 20 msec pulse duration laser set to energy densities of 17-21 J/cm2. Treated areas included arms, legs, beard-chin, upper lips and bikini lines. Gross observation showed leaching of hair color, decresed size of the skin pores, easily broken hair shafts, and elimination of hair. Therefore, it can be assumed that the majority of hair follicles were destroyed by this procedure, Side effects included intermediary risk of hyperpigmentation and blister. Over 80% of treated patients were satisfied with the results. As the process of research and clinical application continues, we need the long-term results of this laser system to ensure its efficacy.

Eosinophilic gastroenteritis is characterized by peripheral eosinophilia, eosinophilic infiltration of the bowel and gastrointestinal symptoms. The disease may affect any area of the gastrointestinal tract. Various manifestations are present, corresponding to the predominant layer of the eosinophilic infiltration. We experienced a case of eosinophilic gastroenteritis presenting as protein-losing enteropathy in a 36-year old male patient with acute upper abdominal pain and watery diarrhea. He showed peripheral eosinophilia, hypoalbuminemia, penile., thigh and ankle edema. The patient was treated with oral corticosteroid, and supportive care such as parenteral albumin, fluid and electrolytes. Almost all symptoms resloved within 1 week. The present report concerns a case of eosinophilic gastroenteritis associated with protein loss. Cases, of eosinophilic gastroenteritis with protein-losing enteropathy are not common. To our knowledge, no case has reported in Korea. So we report this case with brief review of the literature.

8.Misdiagnosis of florid cemento-osseous dysplasia leading to unnecessary root canal treatment: a case report.
Restorative Dentistry & Endodontics 2013;38(3):160-166
This case report demonstrates an unnecessary endodontic treatment of teeth with florid cemento-osseous dysplasia (FCOD) due to a misdiagnosis as periapical pathosis and emphasizes the importance of correct diagnosis to avoid unnecessary treatment. A 30-year-old woman was referred to our institution for apicoectomies of the mandibular left canine and both the lateral incisors. The periapical lesions associated with these teeth had failed to resolve after root canal treatment over a 3-year period. Radiographic examinations revealed multiple lesions on the right canine, the second premolar, and both first molars as well as the anterior region of the mandible. Based on clinical, radiographic and histological evaluations, the patient condition was diagnosed as FCOD. The patient has been monitored for 2 years. To avoid unnecessary invasive treatment, accurate diagnosis is essential before treatment is carried out in managing FCOD.

PURPOSE: To evaluate differential points of clustered microcalcification in malignant and benign lesions on histopathology and correlate with mammographic findings. MATERIALS AND METHODS: Authors evaluated differential points of malignant and benign calcifications in histopathologically confirmed 24 cases. In two patients, mapping studies and paraffin block mammographic examinations were done to correlate calcification on mammography with histopathologic morphology. RESULT: On histopathology, malignant calcifications were located in ductal lumen, while benign ones were usually located in ductal epithelium(p<0.05). However, associated three benign lesions of the 10 malignant lesions showed still benign calcifications adjacent to proven cancer. The typical malignant calcifications were the shape of lamination, while benign calcifications showed granular and salty on light microscope. In 2 mapping studies, malignant-looking calcifications within the area of predominant benign calcifications yielded atypical ductal hyperplasia. Mammographic pepper, granular, punctate, salty and S-shaped calcifications were correlated with granular and salty calcification on light microscope. Mammographic linear, branching, comma, tadpole and wormiform calcifications were correlated with histopathologic laminated calcification. CONCLUSION: Authors have recognized about characteristics of malignant Vs. benign clustered microcalcifications on histopathology. Authors concluded that if malignant-looking calcification such as linear, branching, comma, tadpole and wormiform are present in an are a of predominant benign calcifications, specimen radiographic correlation and mapping study will be necessary for better demonstration of the atypical ductal hyperplasia, hidden or associated breast cancer.
