Purpose: The purpose of this study was to examine the effect of follow-up care on the social support, self-esteem and maternal confidence in mothers of low birth weight infants. Method: This study applied a quasi-experiment study method to examine the pre-post intervention effects. Eighty-eight mothers whose infants were below 2.5kg of Low birth weight were studied. The period for the data collection was from July to December in 2003. Self Reported Survey and Face to Face Interview by the highly trained home Visiting Nurses were used for this study. Result: Most of the participants reported statistically significant improvements in the score of social support, self-esteem and maternal confidence after they received the intervention. Conclusion: Longitudinal study for the mothers of low birth weight infants might reveal more comprehensive findings. Moreover, follow-up care, which is linked with community health care services, is needed to continue the post hospital care services. Additionally, qualified and professional intervention programs should be provided to consider the characteristics of mothers of low birth weight infants.

In the indeterminate chronic period of Chagas disease (ChD) the treatment has not been conclusive, because the serological negativization requires many years. This study aims to evaluate the efficacy of nifurtimox (NF) in the treatment of chronic ChD in prolonged follow-up by serological techniques of indirect immunofluorescence assay (IFA) and enzyme-linked immunosorbent assay (ELISA) IgG comparing 2 groups of patients, treated and non treated. Mann-Whitney test was performed for ELISA and IFA, with significant difference between the groups (P<0.05). IgG levels were lower in individuals treated compared with untreated patients, indicating chemotherapeutic efficacy in prolonged follow-up.

Objective : Placement of a single transverse stent via the nondominant A1 across the anterior communicating artery (AComA) into the contralateral A2 can provide sufficient neck coverage for wide-necked bifurcation AComA aneurysms. The authors described the feasibility, safety and long-term outcomes of this technique. Methods : Between January 2015 and February 2018, placement of a single transverse stent via the nondominant A1 was attempted in 17 wide-necked bifurcation AComA aneurysms. The authors reviewed the medical records and radiological studies. Results : The technical success rate was 94.1% (16/17). Periprocedural thromboembolic complications occurred in one patient (6.3%) without permanent neurological deficits. The mean clinical follow-up duration was 39.9±9.8 months. No deaths or delayed thromboembolic complications occurred. The mean angiographic follow-up duration was 38.9±9.8 months. The immediate and final follow-up complete occlusion rates were 87.4 and 93.7%, respectively. There was no recanalization during the follow-up period. Conclusion : Placement of a single transverse stent via the nondominant A1 across the AComA into the contralateral A2 is a feasible and relatively safe endovascular technique for the treatment of wide-necked bifurcation AComA aneurysms, with good long-term occlusion rates and a reasonable complication rate, if only the nondominant A1 is applicable.

Bariatric surgery is an effective treatment option for obesity, but its effects on reproductive hormones are not well understood. This study aimed to investigate the impact of bariatric surgery on estrogen and progesterone levels in women with obesity. This was a prospective study that included 87 women with obesity who underwent bariatric surgery and 87 control women with obesity who did not. Blood samples were collected at baseline and at 3-month and 6-month follow-up periods to measure reproductive hormones and Adiponectin as well as medical history and physical examination for endometriosis and polycystic ovary syndrome (PCOS). The study found that sleeve gastrectomy significantly increased follicle-stimulating hormone (FSH) and luteinizing hormone (LH) levels in the bariatric surgery group compared to the control group at 3 and 6-month follow-up. There was no significant difference in the mean levels of estrogen and progesterone between the two groups at the 3-month follow-up period. Bariatric surgery leads to significant weight loss in women with obesity, but it does not seem to have a significant impact on estrogen and progesterone levels in the short-term. Future studies with longer follow-up periods are needed to investigate the long-term effects of bariatric surgery on reproductive hormones.

Purpose: We report on the 10-year clinical hip function and radiologic outcomes of patients who underwent hip arthroplasty using a COREN stem. Materials and Methods: A consecutive series of 224 primary cementless hip arthroplasty implantations were performed using a COREN stem between 2009 and 2011; among these, evaluation of 128 hips was performed during a minimum follow-up period of 10 years. The mean age of patients was 65.4 years (range, 40-82 years) and the mean duration of follow-up was 10.8 years (range, 10-12 years). Evaluation of clinical hip function and radiologic implant outcomes was performed according to clinical score, thigh pain, and radiologic analysis. Results: Dramatic improvement of the mean Harris hip score (HHS) from 59.4 preoperatively to 93.5 was observed at the final follow-up (P≤0.01). Stable fixation was demonstrated for all implants with no change in position except for one case of Vancouver type B2 periprosthetic femur fracture. A radiolucent line (RLL) was observed in 16 hips (12.5%). Thigh pain was observed in only two hips (1.6%) at the final follow-up. There were no cases of osteolysis around the stem. The survival rate for the COREN stem was 97.7%. Conclusion: Good long-term survival with excellent clinical and radiological outcomes can be achieved using the COREN femoral stem regardless of Dorr type.

Rastelli operation in which right ventricle[RV and pulmonary artery[PA is connected with an artificial graft is effective in increasing the pulmonary blood flow in certain types of congenital heart disease but, in many, it requires a reoperation because of the relative stenosis of graft that develops as the patients become old. The purpose of this study is to evaluate the various factors which many influence the long term outcome of such patients following a Rastelli operation. A total of 47 patients underwent a Rastelli operation during a 15 year period between November, 1978 and October 1993. The mean follow-up period is 76.1 51.3 months.1 Among the 47 patients, a valved conduit was used in 30[63.8% , and non-valved conduit in 17[36.2% patients. In the 8 patients[17.0% who died postoperatively, a valved conduit was used in 5 [16.6% and a non-valved conduit in 3[17.6% . There was no statistical difference in mortality between the 2 groups. There was a good linear correlation between the body surface area[X and the conduit size[Y [Y=3.86X + 14.6, R=0.55, P=0.01 .2 Ten patients underwent replacement of the conduit during the follow-up period. The type of conduit used and the frequency of subsequent replacement were as follows: Ionescu-Shiley, valved-33.3%, Carpentier-Edwards, valved-30.8%, Hancock, valved-80% and non-valved conduit-9.1%. The median period free of reoperation was 110 months for the valved and 79 months for the non-valved group, there being no statistical difference between the 2 groups. 3 The patients who did not require reoperation are all doing well [New York Heart Association Functional Classification: Class I . Pressure gradient between the RV and the PA was 20 mmHg in 10 randomly selected patients who did not require reoperation and 92 9 mmHg in 10 patients who did require reoperation.4 In the 10 patients who underwent a conduit replacement procedure.5 Among patients undergoing reoperation, 2 died from endocarditis.The remaining 8 patients are doing well without limitation in physical activity at a mean follow-up period of 32.7 33.9 months [range 2 to 89 months . 6 At 5, 7, and 10 years, the reoperation-free rates among all patients were 96%, 91% and 29% and the survival rates were 82%, 82% and 71%. In conclusion, Rastelli operation is an effective procedure in ameliorating symptoms in a select group of patients with congenital heart disease. Because of the inherent nature of relative graft stenosis and degeneration, a long-term follow-up is required under the proper selection of the graft material.

Myasthenia gravis is an autoimmune disease in which the thymus gland is thought to play a central role in the pathogenesis. Thymectomy is now standard therapy, and improvements in surgical techniques, anesthesia, and respiratory care and the use of plasmapheresis have markedly reduced the operative morbidity. We experienced 7 myasthenia gravis with maximal thymectomy from November 1989. As compared with the results of previous classic transsternal thymectomy group the 25 patients who were operated from June 1979 to December 1991[Group B], excellent surgical result was obtained in maximal thymectomy group[Group A]. During follow-up period that ranged from a month to 10.7 years[mean 2 years], the remission rate for the entire group was 15.6 percent and an additional 71.9 percent had improvement[87.5 percent benefited]. In Group A, the remission rate was 42.9 percent with 100 percent of the patients benefiting from operations. But in Group B, 8 percent had remission and a total of 80 percent benefited. In both Groups, there was no operative mortality but there was one case`s mortality in Group B during follow-up period.

This study was to develop the counseling and education program for coping with physical, emotional, and verbal abuse between spouses. Results of empirical study of spouse abuse provided for the basis of designing this program. Consisting of 12 sessions (4 sessions of counseling and 8 sessions of education), the program was delivered to 10 marital couples in an area of Kyunggi-do province. The effectiveness of the program was evaluated through one-group pre-test, post-test, and follow-up test design. Semi-structured interview technique was also employed to evaluate the effectiveness. Resets of paired t-test showed that there were significant differences in several variables between pre-test and post-test period, and this effectiveness remained until follow-up. period. In particular, the degrees of verbal abuse of husbands, and of physical abuse of both husbands and wives were significantly decreased after participating in the program. Also, for both husbands and wives, the Levels of self-esteem and of quality of communication were increased, while the degree of depression was significantly decreased.

Background: Reduced bone height is one of the major problems faced in restoring tooth loss with implants. By the use of short implants, it is possible to reduce complicated and invasive treatment such as bone graft, allowing more simple surgery. But short implants are generally considered to have lower success rates than that of standard implants. Purpose: To assess the results of short Straumann implants by a retrospective study of short Straumann implants with TPS(titanium plasma-sprayed) and SLA(sandblasted, large grit, acid etched) surfaces. Materials and methods: 173 implants in 106 patients who received short Straumann implant surgery(${\le}8\;mm$) in the department of oral and maxillofacial surgery, Kyunghee Dental Hospital, from February 1996 to October 2006 were selected and studied. All of the implants were followed up after prosthetic rehabilitation. The average follow-up period was 34 months with 119 months as the longest follow up period. The average follow-up period after prosthetic rehabilitation was 31 months. 64 females(60.4%) and 42 males(39.6%) participated in the research with the age range of 19 to 85(mean age 47). 20 patients(18.9%) were under 40, 85 patients(80.2%) were over 40 and under 70, and only one patient(0.9%) was over 70 years old. Results: 27 implants(15.6%) had TPS surface while 146 implants(84.4%) had SLA surface. 9 implants(5.2%) were 3.3, 108 implans(62.4%) were 4.1mm and 56 implants(32.4%) were 4.8mm in diameter. 167 implants(96.5%) were 8mm and 6 implants(3.5%) were 6mm in length. There were 24 implants(13.9%) on the maxillas and 149 implants(68.8%) on the mandibles. 119 implants(68.8%) were rehabilitated with FPD(fixed partial denture), 47 implants(27.2%) with single crowns and 4 implants(2.3%) with overdentures. Among the fixed partial dentures, 30 of them were splinted with short implants only. After over an year of follow-up period, 139 implants(96.5%) out of 144 implants showed marginal bone loss of less than 1mm. 3 out of 173 implants failed showing 98.27% survival rate. Conclusions: The use of short Straumann implants(${\le}8mm$) can be a simple and reliable treatment method in minimal residual bone height.

This study examined the effects of a forest environment on internet addition and the self-esteem of internet-addicted adolescents. For comparison, the same group counseling programs were conducted in a classroom not in the forest. Twenty-four second grade students from a Middle School in S-city were grouped with 8 members in each group. Each group joined this program 6 times. The group results were then compared over a follow-up period. The dependent variables were the internet addiction scores and self-esteem scores. In the research results, the experimental group that undertook this program in the forest environment showed significantly different internet addiction scores compared to the control group immediately after the program and during the follow-up period. According to the period, the experimental group showed a significant difference in the internet addiction scores compared to the previous scores, immediately after the program and during the follow-up period. The comparison group showed no significant difference compared to the control group immediately after the program and during the follow-up period. The program in the forest environment showed a significant difference in the self-esteem scores compared to the comparison group and the control group immediately after the program and during the follow-up period. The self-esteem scores of the experimental group increased significantly compared to the comparison group and control group. In addition, the self-esteem scores of the comparison group also increased significantly, compared to the control group. The self-esteem scores of the experimental group also increased significantly, compared to the previous scores, immediately after the program and during the follow-up period. These results suggest that a natural environment, such as a forest, has therapeutic effects on decreasing the addiction symptoms' of internet addiction adolescents and also helps raise their self-esteem. Nevertheless, more study will be needed to verify what effects the forest environment have on the therapeutic mechanism on various addicts. Lastly, the constraints and implications of this research are described.
