Cubitus varus deformity is the late complication of the supracondylar fracture of humerus which is common in growing children. If the deformity is severe it causes tunctional problems as well as cosmetic ones necessitating conective osteotomy. Though many authors devised different methods of corrective osteotomy, the cosmetic results are not always satisfactory because of the development of the lazy S deformity hy the lateral prominence. Technically. the initial stahility of the osteotomy is also poor due to the poor contact of the osteotomy site. So we have devised a new quadrilateral displacement osteotomy to increase the initial stability of the osteotomy by creating a wedge on the osteotomy site & also to prevent the development of the lazy S deformity hy elimination of the Interal prominence. We treated 9 cases of cubitus varus deformity with the new quadrilateral displacement osteotomy. The correction technique was not difficult & the initial stahility of the osteotomy is rather good & the osteotomy is fixed by the conventional methods, & all of the cases were healed uneventfully. There developed no the lazy & deformity after osteotomy. We would like to report the details ot the supracondylnrquadrilateral displacemenl osteotomy.

The purpose of this study was to elucidate the effects of Hwangyun, Hwangyunhaedogtang, and Kumeunhwa on the lymphocyte activity in allergic contact dermatitis induced by contact allergen 1-chloro-2,4-dinitrobenzene (DNCB) of Balb/c mouse. For examination of a contact hypersensitivity, MEST (mouse ear swelling test) and lymphocyte proliferation assay measured by [(3)H]-methylthymidine incorporation were done. Cytokine mRNA in the draining lymph node cells were examined by RT-PCR. Contact hypersensitivity was more effectively induced by 0.25% DNCB treatment than 1% DNCB treatment. Local lymph node cell proliferation from DNCB-sensitized mouse was most highly elicitated with 100 ug/ml DNBS stimulation in vitro. The cytokine profiles of lymph node cells from DNCB-sensitized and DNBS-stimulated mouse were strong expression of IL-2 and IFN-r, weak expression of LT and IL-4, and no expression of IL-6 and IL-10. This lymphocyte proliferation was significantly inhibited in mice administered Korean medical drug for 10 days and sensitized with DNCB at day 5 (88.22%, 65.14%, and 52.29% in Hwangyun, Hwangyunhaedogtang, and Kumeunhwa, respectively). But Kumeunhwa was not effective in the inhibition of lymphocyte proliferation when administered after DNCB-sensitization. The cytokine expressions were also inhibited especially IL-2 and IFN-r in Hwangyun administered- mice. These inhibitions of lymphocyte activity by Korean medical drugs were also observed when stimulated with ConA (1 ug/ml). Conclusively, immune responses of contact hypersensitivity induced by DNCB are involved in local lymph node T cells mainly Th1 type cells, and Korean medical drugs especially Hwangyun suppressed allergic contact dermatitis via inhibition of the activity of these cells.

PURPOSE: To report the clinical features of Adie's tonic pupil. METHODS: The medical records of 22 patients who had been diagnosed with Adie's tonic pupil from February 1998 to February 2009, were retrospectively reviewed. On March 2010, a cross-sectional examination was performed in 16 patients (19 eyes) who underwent a follow-up of more than 1 year. Measurements included pupil size in room light, bright light and in darkness; near point of accommodation; presence of segmental iris palsy; light-near dissociation; denervation supersensitivity; corneal sensitivity; and deep tendon reflex (DTR). RESULTS: Among the patients studied, 16 were women in Adie's tonic pupils. Only 3 of patients had bilateral involvement. The mean age of onset was 38.3 years. The mean size of Adie's tonic pupils was 2.3 mm larger than the fellow eyes. Segmental iris palsy was detected in 93.8% of the patients. Denervation supersensitivity was observed in all patients. Light-near dissociation was present in 88.2% and over 90% of the patients had decreased DTR in the biceps, triceps, knee and ankle jerk. CONCLUSIONS: This cross-sectional study showed Adie's tonic pupil tended to become miotic and recover accommodation power over the years.

Since the new hypertension guideline published by the American Heart Association/American College Cardiology/American Society of Hypertension in 2017, the Korean Society of Hypertension and the European Society of Hypertension revised and announced new hypertension guidelines. Also the Korean Society of Hypertension published Korea hypertension fact sheet 2018, including prevalence, awareness, management status of hypertension, and their trends in Korea. Herein, I provide information on diagnosis and treatment of hypertension based on the new guidelines of the Korean Society of Hypertension.

Primary adenosquamous carcinoma of the ampulla of Vater is extremely rare. We report two cases of adenosquamous carcinoma of the ampulla of Vater in a 48-year-old female and an 80-year-old female patient. The gross appearance was a polypoid mass in both cases. Histologically, the majority of the two tumors was composed of squamous cell carcinoma with some intermingled glandular adenocarcinoma components in both cases. Squamous cell carcinomas showed an abrupt transition from the normal glandular epithelium or glandular adenocarcinoma. Although the two cases revealed duodenal wall invasion and lymph node metastasis was found in case 2, both patients are still alive at 19 and 46 months after surgery, respectively.

Radiation proctitis is a frequent acute complication encountered with pelvic irradiation. This study was aimed at establishing the optimal radiation dose for radiation-induced proctitis in rats. Female Wistar rats were used. The rectal specimens were examined morphologically at 5th and 10th day following 10-30 Gy irradiation in single fraction. With increasing dose, mucosal damage became worse, and there was a prominent reaction after > or =15 Gy. We selected 17.5 Gy as an optimal dose for radiation proctitis and examined specimens at day 1-14 and at week 4, 6, 8, and 12 after 17.5 Gy. The rectal mucosa revealed characteristic histological changes with time. An edema in lamina propria started as early as 1-2 days after irradiation and progressed into acute inflammation. On day 7 and 8, regeneration was observed with or without ulcer. Four weeks later, all regeneration processes have been completed with end result of either fibrosis or normal appearing mucosa. This study showed that the radiation injury of the rectum in rat develops in dose-dependent manner as it has reported in previous studies and suggested that 17.5 Gy in single fraction is the optimum dose to evaluate the protective effect of various medications for radiation proctitis in face of the clinical situation.

PURPOSE: In advanced case of periodontitis, surgical treatment without bone contouring may result in residual pockets inaccessible to proper cleaning during post-treatment maintenance. This problem can be avoided or reduced by applying guided tissue regeneration. MATERIALS AND METHODS: All of 3 patients had deep periodontal pocket depth and bleeding on probing, and radiograph revealed osseous defect, so we planned guided tissue regeneration using resorbable membrane with or without xenograft. RESULT: 6 months later, periodontal pocket depth and bleeding on probing was improved and gingiva was stable. CONCLUSION: Guided tissue regeneration using resorbable membrane with or without xenograft in osseous defect is predictable.
