Purpose@#This study investigated differences in the clinical outcomes of cardiopulmonary resuscitation (CPR) of patients hospitalized in general wards according to the operation of a rapid response team. @*Methods@#This retrospective study included 122 patients over the age of 19 who were admitted to general ward of a hospital located in Suwon, between July 1, 2015 and December 31, 2019, and received CPR during the operating hours of the rapid response team. The collected data were analyzed by descriptive statistics, the x2 test, Fisher's exact test, and one-way analysis of variance using SPSS for Windows version 25.0. @*Results@#The proportion of nurses who were the initial responders to cardiac arrest was 79.1% during the extended-operation period. 41.2% during the pre-operation period, and 42.2% during the limited-operation period (p<.001). The rate of good neurological recovery at discharge post-CPR was 25.0% in patients who received CPR during the pre-operation period, 36.4% during the limited-operation period, and 87.5% during the extended-operation period (p=.042). @*Conclusion@#This study identified clinical outcomes in patients who received CPR according to the operation status of the rapid response team. These results are expected to help in the further implementation of rapid response teams.

Implant assisted removable partial denture with implant surveyed crown: A 20-month follow-up case report / 대한치과보철학회지

Traditional options for posterior edentulous treatment include removable partial dentures and implant fixed prostheses. Recently, the concept of implant assisted removable partial denture, in which two treatments are fused, has been introduced in consideration of systemic health and patient's needs, costs, residual alveolar bone status and so on. Implant assisted removable partial denture has the advantage of increasing the retention and stability of the denture and improving its esthetics in cases of large bone defects or biomechanical disadvantages. In addition, it is possible to strategically place the implants in a site where the alveolar bone is relatively sufficient, thereby overcome the limit of the conventional removable partial denture design as well as reducing the burden on a wide range of implant surgery. Cost reduction is also expected. In this case, the patient was treated by placing the implant in both premolar sites of the mandible and fabricating the distal extension removable partial denture with the implant fixed prosthesis as an abutment. After delivering the definitive prosthesis, the patient showed satisfaction with the masticatory function and esthetics. and has been regularly followed-up for more than one year. The following 20-months follow-up case report describes the design of an implant-assisted-removable partial denture (IARPD) in which two cementretained implant crowns used to provide support and stability.

Evaluation of Marginal and Internal Integrity of Modified Resin-Bonded Fixed Partial Dentures: An In Vitro Study

PURPOSE: The purpose of this study was to evaluate the microleakage of various types of resin-bonded fixed partial dentures (RBFPDs) after artificial aging. MATERIALS AND METHODS: Forty models with missing first molar were fabricated using artificial resin teeth and were divided into four groups: Group A, conventional RBFPDs design; Group B, modified RBFPDs design; Group C, assembled 3-piece RBFPDs design; and Group D, assembled 3-piece RBFPDs with different occlusal rest positions. Half of the specimens underwent chewing simulation process (240,000 cycles, 50 N load, 1.7 Hz) and thermocycling (temperatures 5℃~55℃, dwelling time 30 seconds) and the remaining 20 specimens didn't receive any treatment. All the specimens were immersed in 2% methylene blue solution for 24 hours to evaluate microleakage, and were sectioned at the middle part of abutment teeth. To evaluate the microleaskage, a dye penetration was calculated. RESULT: With artificial aging, cyclic loading and thermocycling, a 3-piece RBPFD and a 2-piece RBPFD using original tooth undercuts have significantly lower microleakge (P<0.05) compared to the conventional design of RBPFD and modified RBPFD. CONCLUSION: Within the limit of this experiment, the assembled RBFPDs exhibited a smaller microleakage than the conventional RBFPDs, implying that the assembled RBFPDs can be more effective for reducing the dislodgement of the RBFPDs.

Reconstruction of anterior guidance using duplication technique of CAD/CAM: a case report / 대한치과보철학회지

Comprehensive prosthetic treatment requires considerations from various points of view. The anterior guidance is important factor in prosthodontic treatment of anterior teeth. Lingual surface contour of anterior restoration is so critical that a small mistake of laboratory or clinical process can cause discomfort of patient and disharmony of entire dentition. There are no guidelines for lingual surface contour that fit all patients. Therefore the lingual surface of provisional restoration is most accurately described as a customized one. The dentist transfers the exact information of anterior guidance that has made through long term provisional restoration to the technician. This case introduce that the duplication technique of CAD/CAM system to reproduce the anterior guidance of provisional restoration. This method can improve satisfaction of both patient and dentist.

Implant overdenture using a locator bar system by drill and tapping technique in a mandible edentulous patient: a case report

Various options have been introduced for the selection of implant overdenture attachments. Attachment wear due to the repeated insertion and removal of dentures has caused problems such as decreased retention and the requirement for suprastructure remanufacturing. In these cases, a Locator bar system was applied using the drill and tapping technique to achieve total retrievability. In a 55-year-old female patient who showed three degrees of mobility in most of her teeth due to severe alveolar bone loss, a complete denture in the maxilla and an implant supported type overdenture in the mandible were planned after extracting all the remaining teeth. Six implants were placed from canine region to the distal molar region, and the locator was connected to the milled bar using the drill and tapping technique. For a 61-year-old female edentulous patient who complained of poor retention with old denture, a complete denture in the maxilla and an implant-tissue supported type overdenture in the mandible were planned. Four implants were placed in front of mental foramen, and the Locator was also connected to the Hader bar using the drill and tapping technique. With this technique, female parts can be easily replaced, and retention can be continuously maintained.

The Effect of Ovariectomy on The Secretion of Follicle Stimulating Hormone ( FSH ) and mRNA Levels of FSHbeta subunit in Rat / 대한산부인과학회잡지

Follicle stmulating hormone ( FSH ) consist of alpha and beta subunits, which are encoded by se-parate genes. Pituitary release of FSH appears to be regulated by the hypothalamic GnRH and the gonadal steroid hormones. In addition, inhibin and follistatin produced by the gonad have been known to inhibit FSH secretion selectively. However, little is known about their regulation of the biosynthesis of FSH subunits at transcriptional and posttranscriptional levels. In the pre-sent study, we studied the time course of changes in alpha and FSH beta subunit mRNA concentrati-ons after castration and the effects of ovarian steroids of changes in alpha and FSH beta subunit mRNA concentrations after castration and the effects of ovarian steroids on alpha and FSH beta subunit mRNA in ovariectomized rats in order to determine Whether FSH subunit synthesis is modulated at the pretranslational levels, and whether synthesis and secretion are differently regulated. Results are as follows : 1. The time course of the rise in the steady state alpha subunit and FSH beta subunit mRNA levels were observed after ovariectomy, which paralleled the increases in serum and pituitary FSH concentrations. The time course experiments revealed differences in the patterns of alpha and FSH beta subunit mRNA responses, the rise in FSH beta subunit mRNA levels being more pro- minent than the rise in alpha subunit mRNA. 2. FSH beta mRNA levels were negatively regulated by the single injection of progesterone but not by estradiol, suggesting that FSH beta subunit mRNA seemed to be more sensitive to ne-gative feedback by progesterone than estradiol. Similar results were obtained by the continuous treatment of ovarian steroids for 1~4 days, but inhibition was more prominent with continuous treatment. It is, therefore, concluded that estradiol and progesterone inhibit the synthesis of FSH at the pretranslational level by modulating the steady state levels of alpha and FSH beta subunit mRNA, progesterone effect being more promiment than that of estradiol and alpha and FSH beta subunit are regulated in a different manner.
