Intraosseous ganglion is an uncommon benign tumor thought to be caused by an intramedullary metaplastic event. We recently experienced a case of intraosseous ganglion that occurred on the femoral head of a 65-year old man who complained of intermittent hip pain. Complete evaluation including bone scan, CT, MRI was done. His pain disappeared after curettage and bone graft was done on the lesion.

We developed an animal model to recreate the condition of an open fracture in communication with the maxillary sinus. We then studied wound healing of the sinus wall structures following fracture in the presence of autogenous bone and alloplastic implant. This model is designed to simulate the repair of an orbital floor fracture in humans. The New Zealand White rabbit was used as the animal model. Standardized 8mm defects were made bilaterally in the maxillary sinuses to include bone and mucosa in 36 rabbits. Two different implants and autogenous calvarial bone graft were placed in the soft-tissue pockets to obturate the defects, exposing one surface of the implant to the open sinus. Medpor porous polyethylene, silicone and calvarial bone implant were compared. Animals were killed at 1, 2 and 8 weeks after implantation. Gross examination of the specimens for the amount of mucosal closure and implant tissue fixation was performed. Histological sections were evaluated for bone and soft-tissue morphology juxtaposed to the implant. Complete closure of the mucosal defect was demonstrated with each type of implant. Medpor implants showed both vascular and soft-tissue ingrowth into pores by week 1. Bone ingrowth was seen by week 2. Closure of the Medpor obturated defects occurred more rapidly than in the silicone group. The Medpor implants and calvarial bone demonstrated bone and soft-tissue fixation, callus formation and maturation, while mature overlying mucosa was reconstituted over the defects. Silicone implants demonstrated a fibrous tissue reaction within 1 week of implantation and they never became fixed to bone or soft tissue. Maxillary sinus wall regeneration occurred in all defects. This study supports clinical observations of maxillary sinus wall regeneration in humans.

Lidocaine is considered a safe and effective local anesthetic in anesthesiology and is the standard to which new amide anesthetics are compared. As it an amide derivative, and the frequency with which lidocaine elicits an allergic response is much less than that of anesthetics derived from paraaminobenroic acid esters. Case reports od sensitivity to lidoeaine have been reported, but they are rare. This 29 year old male patient had on episode of asthmatic breathing after supraclavicular brachial plexus block using 30 ml of 1% lidocaine with epinephrine(1:200,000). We report a case of asthmatic breathing due to lidocaine and a review of the literature for allergy local anesthetics.

The relationship between respiratory infections and exacerbations of wheezing in patients with wheezy bronchitis or asthma has been described. Most respiratory infections were viral or Mycoplasma pneumoniae. This study was performed to evaluate the effect of Mycoplasma pneumoniae infection on bronchial reactivity and atopic background. 106 patients with Mycoplasma pneumoniae pneumonia who were admitted to the department of pediatrics, Fatima Hospital, Taegu during the period of two years from January 1989 to December 1990 were involved in this study. The results were as follows 1) Out of 106 cases, 69 were male,37 were female and 34.9% of the cases were between 5~6 years of age. 35 cases(33.0%) had wheezing and the incidence of wheezing were higher in male than in female. 2) The incidence of wheezing was high in the patients with serum IgE level higher than 200IU/ml, patients with past and family history of allergy and the patients fed with formula feeding in infancy. 3) Eosinophils and the associated maxillary sinusitis had no effect on the incidence of wheezing. 4) The recurrence of wheezing was higher in Mycoplasma pneumoniae pneumonia with wheezing(26.8%) than in patients without wheezing(3.8%).

PURPOSE: This study was done to explore the lived experience of pregnancy, childbirth, postpartum and early child rearing in married immigrant women in urban areas. METHODS: Data were collected from February to April, 2011 through in-depth interviews. Nine immigrant women were selected in a metropolitan area through the purposive and snowball sampling method. After obtaining IRB permission and informed consent from the participants, all interviews were recorded with MP3 recorder and transcribed for analysis. Using the phenomenological approach, data collected through in-depth interviewing were analyzed following Colaizzi style. RESULTS: Data analysis revealed 4 categories and 10 themes related to pregnancy, childbirth, postpartum and early child rearing of married immigrant women in urban areas. These four categories were 'A clumsy foreigner's life with nostalgia', 'Crisis in the crisis', 'Unprepared for motherhood', and 'Living together with new family without regrets'. It was a common finding that they were not ready to be mothers because of the very short time for adjustment in Korea. Compared to rural, immigrant women urban women had various in social support systems. CONCLUSION: The results indicate that adequate education is needed for immigrant women regarding motherhood, and that this education should be culturally appropriate for these women.

PURPOSE: The purpose of this study was to investigate the experience and perception of sexual harassment during the clinical practice among nursing students and to identify the relationship between these variables and self-esteem. METHODS: Participants included 191 senior nursing students who voluntarily participated. Sexual harassment experiences and perceptions were measured using the tools developed by the researcher. Self-esteem was measured using self-esteem inventory developed by Rogenberg. RESULTS: 50.8% of the participants experienced sexual harassment. Physical harassment was the most common, followed by verbal, visual and gender-role related sexual harassment. ‘Blocking the way’ and ‘Brushing one's body on purpose’ were the most common behaviors. The perception of sexual harassment severity was 3.35 out of 5 points. There were negative correlation between sexual harassment experience and self-esteem (r=-.17, p=.013). The subjects who experienced sexual harassment showed lower self-esteem score than those who did not (t=-2.10, p=.037). The main offender was a male patient in 40s, and the psychiatric ward was the most vulnerable to sexual harassment. CONCLUSION: Results showed that sexual harassment in clinical practice among nursing students were serious. It is necessary to develop an educational program to prepare them for sexual harassment in clinical practice.

A considerable body of evidence has been accumulated suggesting that invasive squamous cell carcinoma develops from cervical intraepithelial neoplasia(CIN). Most women with invasive cancer of the cervix are from lower socioeconomic groups, have begun heterosexual activity early in life, marry early, are multiparous, and have many sexual partners. Although the epidemiology of the cervical cancer is known well, the pathogenesis of the cervical cancer from CIN is subtle yet. Apoptosis, including the programmed cell death, is important event in normal cell turnover and maintenance of adult tissues. Apoptosis exerts a homeostatic function in relation to tissues dynamics, as the steady state of continuously renewing tissues achieved by a balance between cell replication and cell death. The specific labelling of nick ends of fragmented DNA was used to see the apoptotic cells from normal epithelium of the cervix to invasive cervical cancer. The apoptotic cells were found normally in the parabasal layer of the epithelium. As the grade of CIN increase, the apoptotic cell were found in superficial of the cervix and number of the apoptotic cell were increased. In the cervical cancer, the apoptotic cell were found in the cancerous tissues more than in the normal epithelium. This results suggest that the cell proliferation is more important than the inhibition of the apoptosis in the carcinogenesis of the cervical cancer.

OBJECTIVE: Mammalian follicle cells are the most important somatic cells which help oocytes grow, mature and ovulate and thus are believed to provide oocytes with various functional and structural components. In the present study we have examined whether cumulus or granulosa cells might play a role in establishing the plasma membrane structure of mouse oocytes during meiotic maturation. DESIGN: In particular the differential resistances of mouse oocytes against chymotrypsin treatment were examined following culture with or without cumulus or granulosa cells, or in these cell-conditioned media. RESULTS: When mouse denuded oocytes, freed from their surrounding cumulus cells, were cultured in vitro for 17~18 hr and then treated with 1% chymotrypsin, half of the oocytes underwent degeneration within 37.5 min (t50=37.5+/-7.5 min) after the treatment. In contrast cumulus-enclosed oocytes showed t50=207.0. Similarly, when oocytes were co-cultured with cumulus cells which were not associated with the oocytes but present in the same medium, the t50 of co-cultured oocytes was 177.5+/-13.1 min. Furthermore, when oocytes were cultured in the cumulus cell-conditioned medium, t50 of these oocytes was 190.0+/-10.8 min whereas t50 of the oocytes cultured in M16 alone was 25.5+/-2.9 min. Granulosa cell-conditioned medium also increased the resistance of oocytes against chymotrypsin treatment such that t50 of oocytes cultured in granulosa cell-conditioned medium was 152.5+/-19.0 min while that of oocytes cultured in M16 alone was 70.0+/-8.2 min. To see what molecular components of follicle cell-conditioned medium are involved in the above effects, the granulosa cell-conditioned medium was separated into two factions by using Microcon-10 membrane filter having a 10 kDa cut-off range. When denuded oocytes were cultured in medium containing the retentate, t50 of the oocytes was 70.0+/-10.5 min. In contrast, t50 of the denuded oocytes cultured in medium containing the filtrate was 142.0+/-26.5 min. T50 of denuded oocytes cultured in medium containing both retentate and filtrate was 188.0+/- 13.6 min. However, t50 of denuded oocytes cultured in M16 alone was 70.0 +/-11.0 min and that of oocytes cultured in whole granulosa cell-conditioned medium was 156.0+/-27.9 min. When surface membrane proteins of oocytes were electrophoretically analyzed, no difference was found between the protein profiles of oocytes cultured in M16 alone and of those cultured in the filtrate. CONCLUSIONS: Based upon these results, it is concluded that mouse follicle cells secrete a factor(s) which enhance the resistance of mouse oocytes against a proteolytic enzyme treatment. The factor appears to be a small molecules having a molecular weight less than 10 kDa.
