OBJECTIVE: To evaluate the changes of bladder management methods after the discharge from hospital, and to identify the problems associated with their method changes of bladder management after the discharge. METHOD: The subjects of this study were 128 spinal cord injury patients with a neurogenic bladder dysfunction who were admitted to the hospital and received the neurogenic bladder management and training. We reviewed the medical records of these patients for the management methods of neurogenic bladder and interviewed the patients whether they are still using the same methods after the discharge. RESULTS: The number of patients who were doing the intermittent catheterization at the time of discharge from hospital was markedly reduced after the discharge and most of the patients in this group have switched to the external collecting device method, using Cred, Valsalva or tapping method. The reasons of this change were that the intermittent catheterization method was not only difficulty and complicated but also restricted their social activities. CONCLUSION: We concluded that a long term close follow up and continuous encouragement are very important in the management of neurogenic bladder patients who are discharged with the intermittent catheterization method.

PURPOSE: Articles reporting on the wear rate of polyethylene cup in hybrid THA are rare. So, we now report the results of wear rate of polyethylene in cementless Harris-Galante acetabular components and cemented Harris precoat femoral stem. MATERIALS AND METHODS: The cementless Harris-Galante acetabular components and cemented Harris precoat femoral stem of one-hundred hips in 71 patients were followed up for 2.5 ~ 7.5 years (mean 4.7 year) . The clinical results were evaluated by Harris hip score (HHS) and wear rates were measured using Livermore technique. RESULTS: The most recent follow-up of HHS was improved from 52 to 91 in average. The mean linear wear rate in cemetless acetabular component was 0.17 0.06mm/yr (range 0.05 ~ 0.35) . Two femoral components were revised for aseptic loosening and one acetabular component revised for aseptic loosening. Wear rate in the revision group was higher than mean wear rate. In chronological change of wear rate according to final follow up period, there was decreasing tendency for mean wear rate with time. There was no correlation found between mean wear rate and body weight. There was a decreasing tendency on mean wear rate with acetabular cup shell size and increasing tendency with level of activity. CONCLUSION: We concluded that cemented femoral stem was the reason for the trend in lower wear rate of polyethylene cup than which had been previously reported in cementless THA, but further follow-up studies will be needed to confirm that.

Excessive wear causes many complications when untreated, so that accurate diagnosis, analysis and predictive treatment plan should be made, and through evaluation of vertical dimension and stepwise treatment, a stable inter-arch relationship can be set. For the long-term success of implant treatment, ideal position and angle of implant is important, and its importance increases especially in multiple implant cases. Therefore, thorough diagnosis and planning, accurate surgery and prosthodontic procedures are significant. In this case, a 68-year-old male patient with a loss of vertical dimension due to multiple tooth loss and overall tooth wear was planned with systematic analyses from the pre-treatment stage to rehabilitate vertical dimension. Full-mouth fixed rehabilitation with computer tomography guided implant surgery was performed to the newly set vertical dimension and attained satisfactory outcomes both functionally and esthetically.

Background:
Despite their effectiveness, coronavirus disease 2019 (COVID-19) vaccines have been associated with adverse effects, underscoring the importance of continuous surveillance to ensure vaccine safety and effective management of public health. Herein, the characteristics and risk factors of vaccine-related adverse events (AEs) were identified to gain an in-depth understanding of vaccine safety by investigating the impact of the vaccination dose on changes in post-vaccination AEs.
Methods:
Herein, a linked database of COVID-19 vaccination records from the Korea Disease Control and Prevention Agency, AE reports from the COVID-19 Vaccination Management System, and healthcare claims from the National Health Insurance Service, targeting ≥ 5-year-old individuals, was utilized (study duration = February 26, 2021, to January 31, 2023).The frequency and severity of reported post-vaccination AEs were evaluated. Furthermore, we specifically explored AEs in relation to the cumulative dosage of vaccines administered while evaluating associated risk factors.
Results:
During the observation period, 42,804,523 individuals completed the COVID-19 vaccination series, with 365,900 reporting AEs, with headache, muscle pain, and fever being the most frequently reported. Notably, the AE reports were approximately twice as high for women than for men, which was further exacerbated following both doses. Analysis by age group revealed that AE reports were lower among children, adolescents, and older adults than in the middleaged cohort (age = 50–64 years), with higher reports observed for 18–49-year-old individuals.Additionally, a higher risk of reporting was identified among individuals with lower socioeconomic status compared with those of middle socioeconomic status. Excluding dementia, the risk of reporting AEs was high in individuals with underlying diseases compared with those without, for instance, the risk of reporting AEs following two-dose vaccinations was approximately twice as high in individuals with chronic obstructive pulmonary disease and asthma.
Conclusion
These findings indicate that women, younger people, those with a lower socioeconomic status, and those with underlying health conditions reported a higher incidence of AEs following COVID-19 vaccinations. This emphasizes the need for continued monitoring to ensure safe vaccination and address vaccine-related anxiety and fear, especially within the aforementioned groups.

PURPOSE: Tumor invasion and metastasis are known to be extremely important factors in the prognosis of cancer patients. Although recent studies have demonstrated that cyclooxygenase-2 (COX-2) is overexpressed in various cancers including gastric cancer, the mechanisms underlying the contribution of COX-2 to tumorigenesis and tumor promotion remain unclear. METHODS: In order to determine the role of COX-2 in tumor growth and metastasis, we investigated COX-2 expression, apoptosis and the expression of E-cadherin, CD44v6, MMP-2 and TIMP-2 in gastric cancer xenografts treated with meloxicam (a selective COX-2 inhibitor). RESULTS: Cells from the MKN45 gastric cancer cell line that overexpress COX-2 were inoculated subcutaneously into athymic mice. Oral administration with meloxicam reduced the tumor volume (P<0.01), induced apoptosis of cancer cells (P<0.01), suppressed the proliferation rates (P<0.01), increased the expression of E-cadhrin (P<0.05) and reduced the expression of MMP-2 and TIMP-2. CONCLUSION: The above data showed that COX-2 inhibitors can inhibit tumor growth and suppress metastatic potential by expression of adhesion molecules and suppression of metalloproteinases, suggesting that this inhibitor can be used as an additive anti-cancer drug in cases of stomach cancer with radical resection, although further evaluation is required.

PURPOSE: PTEN is a novel tumor suppressor gene located on chromosomal band 10q23.3. The detection of PTEN mutations in Cowden disease and in breast carcinoma cell lines suggests that PTEN may be involved in mammary carcinogenesis. Among several series of breast carcinomas, the frequency of loss of flanking markers around PTEN is approximately 30 to 40% and the somatic intragenic PTEN mutation frequency is less than 5%. METHODS: The expression of PTEN was stuided immunohistochemically studied in 41 invasive ductal carcinomas of the breast. We examined the correlation between PTEN expression and clinicopathologic factors such as age, tumor size, lymph node metastasis, histologic grade, nuclear grade, stage, as well as estrogen and progesteron receptors. RESULTS: Among the 41 infiltrating ductal carcinomas, studied 7 (17.1%) were immunohistochemically negative, and 19 (46.3%) demonstrated reduced expression. Among the clinicopathologic factors, tumor size, lymph node metastasis, high stage, and negative progesteron receptor displayed a significant relationship with the decrease of PTEN expression, however age, nuclear grade, and estrogen receptor had less of a relationship with PTEN expression. CONCLUSION: These results suggest that PTEN does play some role as a prognostic factor for carcinogenesis, but this hypothesis requires further study.

PURPOSE: In general, tumor growth is dependent on angiogenesis. COX, known as modulator of angiogenesis, consists of two at least isozymes constitutive COX-1 and stress- induced COX-2. The latter is known in case of gastric cancer to be overexpressed in neoplastic tissue but not in adjacent normal tissue. To clarify the effect of COX-2 inhibitors on tumor growth and angiogenesis, we investigated the effects of Meloxicam (a selective COX-2 inhibitor) on gastric cancer xenograft in nude mise that overexpress COX-2. METHODS: MKN45 gastric cancer cell lines that overexpress COX-2 were inoculated subcutaneously into athymic mice. The mean tumor volume, apoptotic index, proliferative index, microvessel count and angiogenic factors (VEGF and bFGF) were measured in the control group (12 cases) and the meloxicam treated group (23 cases). RESULTS: There was no significant difference of COX-2 expression between the control and meloxicam treated groups in mRNA level as measured by RT-PCR, nor in protein level by Western blotting. However, in the meloxicam treated group, apoptosis was increased to a statistically significant degree (P<0.01) while the proliferation index as measured by Ki-67, the mean tumor volume and angiogenesis were all significantly decreased, as compared with the control group (P<0.01). CONCLUSION: The possible suppression of angiogenesis and tumor growth in gastric cancer xenograft by meloxicam suggests potentially. Novel and promising applications of COX-2 inhibitors in the adjuvant treatment of gastric cancer. However, further clinical study will be needed to determine its efficacy in such treatment modalities.

PURPOSE: Angiogenesis plays an important role in the growth, progression and metastasis of solid tumors. Vascular endothelial growth factor (VEGF) was thought to be one such angiogenic factor and was also thought to be a selective mitogen for endothelial cells. The purpose of this retrospective study was to evaluate for prognostic significance of VEGF in stomach cancer. MATERIALS AND METHODS: The sections of formalin-fixed, paraffin embedded from 55 stomach cancer were stained immunohistochemically for VEGF. The rate of VEGF expression and correlation between expression of VEGF and other prognostic factor of stomach cancer were studied. RESULTS: There were 20 cases (36.4%) of VEGF-positive and 35 cases (63.6%) of VEGF- negative. There were no significant difference between VEGF expression and the histologic type, differentiation, depth of invasion of histologic stage, lymph node involvement. The frequency of hepatic recurrence was higher in patients with VEGF-positive tumor than that af patient with negative tumor (p=0.007). The prognosis of the patients with VEGF positive tumor was worse than that of patients with VEGF negative tumor (p=0.0214). CONCLUSION: There was a closely significant between positive expression of VEGF and a high incidence of hepatic metastasis, low survival rate. The expression of VEGF could be considered to be one of useful prognostic factor in human gastric carcinoma

PURPOSE: This study was aimed to determine the role of the VEGF and MVD expression in infiltrating ductal carcinoma of breast and to observe the correlation between the expression of these VEGF/MVD, and other prognostic factors. MATERIALS AND METHODS: Immunohistochemical staining of VEGF and MVD with monoclonal antibody in pathologic specimens of 35 patients of infiltrating ductal carcinoma of breast was carried out. Reiationship between the expression of the VEGF/MVD and prognostic factors were assessed. RESULTS: The VEGF/MVD expression was closely related to tumor size, lymph node metastasis, and clinical stage, but not related to histologic grade, nuclear grade, estrogen receptor, and progestrone receptor. And the VEGF expression was closely related to MVD. CONCLUSION: The VEGF expression and microvessel density in infiltrating ductal carcinoma of breast may play an important prognostic factors, closely related to the tumor size, lymph node metastasis, and stage.

PURPOSE: The genetic alteration of the janus kinases (JAKs), non-receptor tyrosine kinase, is related to the development of human cancers. However, little is known about how the sequence variation of JAK3 contributes to the development of lung cancer. This study investigated whether polymorphisms at the promoter region of the JAK3 gene are associated with the risk of lung cancer in the Korean population. MATERIALS AND METHODS: A total of 819 subjects, including 409 lung cancer patients and 410 healthy controls were recruited. The SNaPshot assay and polymerase chain reaction-restriction fragment length polymorphism analysis were used, and logistic regression analyses were performed to characterize the association between polymorphisms of JAK3 and lung cancer risk. RESULTS: Three polymorphisms (-672 G>A, +64 A>G and +227 G>A) of JAK3 were analyzed for large-scale genotyping (n=819). Statistical analyses revealed that polymorphisms and haplotypes in the JAK3 gene were not significantly associated with lung cancer. CONCLUSION: JAK3 gene was not significantly associated with the risk of lung cancer in the Korean population.
