The purpose of this study was to examine the effect of smoking on the clinical, radiographic outcome of surgical peridontal therapy. The outcome of periodontal surgery was evaluated in 51 systemically healthy subjects that had received maintenance care. The study subjects consisted of 26 smokers and 25 non-smokers. The average age of smoking patients was 51 years old and non-smoking patients was 48 years old. Changes of probing pocket depth(PPD) and radiographic bone height, and number of missing teeth compared between smokers and non-smokers during maintenance period after surgical therapy. The clinical parameters were less favorable in the smoking group compared with non-smoking group. The number and percentage of missing teeth were greater in smokers(21.6%) than non- smokers(12.4%), especially in molars. The mean presurgery PPD was similar in smokers and non-smokers, molars and premolars, but significantly decreased at least 2 years after surgery. The mean PPD reduction was significantly greater in nonsmokers than smokers. Both in the smoking and non-smoking group, the mean PPD reduction was significantly greater in premolars than molars. The radiographical evaluation was also less favorable in the smoking group than non-smoking group. The radiographic evaluation of bone height in smokers showed bone loss. On the contrary, bone height of nonsmokers showed bone gain during the period of maintenance. But there was no significant difference between molars and premolars. The clinical and radiographic outcomes of the smoking group was less favorable than those of the nonsmoking group. Therefore, smoking seems to influence on the clinical and radiographic outcomes of surgical periodontal therapy.

Due to its safety and softness, autologous fat transplantation has been commonly performed for soft tissue correction. However, the injected fat is absorbed resulting in the reduction of volume of the graft by 40- 60% within a few months. Thus, there was an attempt to use adipocytes differentiated from preadipocytes in vitro for transplantation. Differentiated adipocytes were biocompatible and matured with gradual volume increase at transplantation site in clinical study(unpublished data). In addition, they did not induce immune rejection in response to nonself lymphocytes in a mixed lymphocyte reaction(MLR)(unpublished data). The purpose of this study is to differentiate mouse preadipocytes following labeling into adipocytes to establish an animal model for allogenic transplantation. Preadipocytes isolated from inguinal and retroperitoneal fat pad of C57BL/6 mice were proliferated with growth medium by passage 3 and differentiated into adipocytes with different culture conditions after labeled with BrdU. At most suitable conditions, above 90% of preadipocytes were differentiated and BrdU labeling did not affect differentiation rate and function of differentiated adipocytes. These results demonstrate that BrdU-labeled adipocytes resulting from this in vitro differentiation protocol are useful for allogenic transplantation study.

Myoma is the most common tumor in gynecologic field. As ultrasonography because popular in antenatal care, the more cases of myoma and those adverse effects during pregnancy are more frequently detected. The management of myoma during pregnancy is conservative, but in rare circumstances, surgical intervention including myomectomy may be required. We have experienced a case of protruded subserosal myoma with the uterine cervix in midtrimester of pregnancy. The patient was managed surgically by transvaginal myomectomy and had successfully maintained pregnancy. We report a case of protruded subserosal myoma through pelvic floor in pregnancy with brief review of literatures.

Antiestrogens have been widely used in the treatment of breast cancer patients. Although tamoxifen is one of the most prevalent antiestrogens, some reported its hepatocarcinogenic effects and the long-term treatment may increase the risk of endometrial and gastrointestinal cancer. Toremifene is an interesting new antiestrogen and have a similar antitumor efficacy as tamoxifen, with less side-effect including less uterotrophic effect compared to tamoxifen, in mice. we report a case of endometrial polyp which were associated with toremifene use, in postmenopausal woman with breast cancer, with a brief review of literature.

Clear cell adenocarcinoma (CCAC) is a rare cancer that comprises less than 9% of the cervical adenocarcinoma cases. We experienced a case of fertility-sparing radical abdominal trachelectomy for cervical clear cell adenocarcinoma (CCAC). Thus, reported it. A 27 year old female was diagnosed with clinical stage Ib cervical CCAC. She had no history of maternal exposure to diethylstilbestrol and had negative PAP cytology and HPV tests. She was treated with neoadjuvant chemotherapy followed by radical abdominal trachelectomy. After 2 cycles of postoperative adjuvant chemotherapy, the lesion disappeared completely in an imaging study, and potential fertility was preserved. Radical abdominal trachelectomy with chemotherapy may be a valuable approach for treating stage Ib cervical CCAC in women that wish to preserve potential fertility.

BACKGROUND: Death domain-associated protein (DAXX), originally identified as a pro-apoptotic protein, is now understood to be either a pro-apoptotic or an anti-apoptotic factor with a chromatin remodeler, depending on the cell type and context. This study evaluated DAXX expression and its clinical implications in squamous cell carcinoma of the esophagus. METHODS: Paraffin-embedded tissues from 60 cases of esophageal squamous carcinoma were analyzed immunohistochemically. An immune reaction with more than 10% of tumor cells was interpreted as positive. Positive reactions were sorted into 2 groups: reactions in 11%–50% of tumor cells and reactions in more than 51% of tumor cells, and the correlations between expression and survival and clinical prognosticators were analyzed. RESULTS: Forty-three of the 60 cases (71.7%) showed strong nuclear DAXX expression, among which 19 cases showed a positive reaction (31.7%) in 11%–50% of tumor cells, and 24 cases (40.0%) showed a positive reaction in more than 51% of tumor cells. A negative reaction was found in 17 cases (28.3%). These patterns of immunostaining were significantly associated with the N stage (p=0.005) and American Joint Committee on Cancer stage (p=0.001), but overall survival showed no significant difference. There were no correlations of DAXX expression with age, gender, or T stage. However, in stage IIB (p=0.046) and stage IV (p=0.014) disease, DAXX expression was significantly correlated with survival. CONCLUSION: This investigation found upregulation of DAXX in esophageal cancer, with a 71.7% expression rate. DAXX immunostaining could be used in clinical practice to predict aggressive tumors with lymph node metastasis in advanced-stage disease, especially in stages IIB and IV.

Hydramnios is a serious complication of pregnancy associated with a marked increase in perinatal mortality. A variety causes of this condition have been described, the majority of which relate to abnormalities of the fetus. Myotonic dystrophy is a progressive degenerative disease of the neuromuscular system, usually inherited in an autosomal dominant fashion. The disease is variable onset and clinical manifestations and usually severe in the male. Especially congenital myotonic dystrophy is a disease characterized by profound hypotonia. Affected infants present with varying degrees of respiratory failure, often necessitating immediate and prolonged ventilatory assistance. These neonates also have feeding difficulties due to impaired sucking and swallowing. The diagnosis of myotonic dystrophy in pregnancy is made retrospectively, following the birth of a severely affected neonates. A documented case of congenital myotonic dystrophy associated with hydramnios in two successive pregnancies is presented. The evidence suggests that myotonic dystrophy should be considered as a rare cause of recurrent hydramnios. We report a case of recurrent hyramnios in association with congenital myotonic dystrophy with a brief review of literatures.

OBJECTIVE: To estimate hours of leisure time physical activity (LTPA) performed by people with chronic spinal cord injury (SCI) and to identify the demographic and injury-related characteristics associated with LTPA of people with chronic SCI. METHOD: Seventy nine persons with SCI living in Busan and Gyongsangnam-do were recruited. They completed a self-administered questionnaire, which consisted of items about personal characteristics, type of LTPA, hours of LTPA, LTPA intensity, and LTPA satisfaction. RESULTS: Most participants (92.4%) did not work. The respondents reported a daily mean of 3.13 hours (+/-1.47) of LTPA; however, 3.8% reported no LTPA whatsoever. Years post-injury, income sources, and type of medical payment emerged as a predictors of LTPA. Years post-injury were positively correlated with amount of leisure activity. In the case of self income, LTPA was longer than for groups with different income sources (e.g.partner, parents). For patients receiving workers' compensation insurance, LTPA was longer than for patients receiving non-WC insurance. Most LTPA was done at a moderate intensity. The three most frequently reported types of LTPA were wheeling (26%), sports (19%), and stretching exercise (15%). There was overall dissatisfaction with LTPA. CONCLUSION: Daily LTPA hours were longer than previously reported, but wheeling accounted for a large part of the activity. Intensity of activity was generally moderate. The employment rate was very low. Clearly, participating in regular LTPA for health purposes is very important to people with chronic SCI, but it is also important for them to have jobs.

Presently talc is one of the agents most commonly used for producing a pleurodesis in patients with either a recurrent pleural effusion or a spontaneous pneumothorax. Talc can be instilled into the pleural space either as an aerosol (insufflation) or as a suspension (slurry) in saline. They are quite effective in producing a pleurodesis. However, they rarely have acute serious adverse effects including acute respiratory distress syndrome, and recently a discussion for using pleurodesis has been reported. We experienced a case of acute respiratory distressed syndrome after talc pleurodesis. A 64 year old man, who was diagnosed lung cancer with a malignant pleural effusion at the same side, was treated by pleurodesis using talc to control the effusion. After 3 days, he suffered fever, chill and breathlessness. The chest PA and CT revealed a bilateral infiltration in both lungs and the blood gas analysis confirmed hypoxemia, which required mechanical ventilation.
