OBJECTIVES: Our study aims to provide basic scientific data on the importance of obesity management in middle-aged Korean women by analyzing its effects on blood pressure and arterial stiffness. In addition, we examined the correlations of these two parameters. METHODS: The study participants were 40 middle-aged female volunteers, who were classified into obesity group (n = 20) and normal weight group (n = 20). Statistical analysis was performed using independent t-test and the Pearson correlation coefficient was used to correlate blood pressure and arterial stiffness. RESULTS: This study evaluated the systolic blood pressure, diastolic blood pressure, and pulse wave velocity (PWV). These results were higher in the obesity group than the normal weight group. Furthermore, blood pressure and arterial stiffness (PWV, augmentation pressure) were static correlated. CONCLUSION: Obesity is closely related to blood pressure and arterial stiffness. Therefore, indices for blood pressure and arterial stiffness may play a vital role in predicting and preventing obesity and its sequelae.

Objective: To evaluate the safety and effectiveness of the community-based cardiac rehabilitation (CBCR) program that we had developed. Methods: Individuals aged >40 years with cardiovascular disease or its risk factors who were residing in a rural area were recruited as study subjects. The CBCR program, which consisted of 10 education sessions and 20 weeks of customized exercises (twice a week), was conducted in a public health center for 22 weeks. Comprehensive outcomes including body weight, blood glucose level, and 6-minute walk distance (6MWD) were measured at baseline, 11th week, and completion. Furthermore, the outcomes of young-old (65–74 years) and old-old (≥75 years) female subjects were compared. Results: Of 31 subjects, 21 completed the program (completion rate, 67.7%). No adverse events were observed, and none of the subjects discontinued the exercise program because of chest pain, dyspnea, and increased blood pressure. Body weight and blood glucose level were significantly decreased, and 6MWD was significantly increased following program implementation (p<0.05). Both young-old and old-old women exhibited an improvement in blood glucose level and 6MWD test (p<0.05). Conclusion We reported the results of the first attempted CBCR in South Korea that was implemented without adverse events during the entire program. Improved aerobic exercise ability and reduced risk factors in all participants were observed. These improvements were also achieved by older adults aged ≥75 years.

Purpose: This study aimed to evaluate the effect of repeated use of an implant handpiece under an implant placement torque (35 Ncm) and overloading torque condition (50 Ncm) on an output torque. Materials and Methods: Two types of implant handpiece systems (Surgicpro/X-DSG20L [NSK, Kanuma, Japan] and SIP20/CRB46LN [SAESHIN, Daegu, South Korea]) were used. The output torque was measured using a digital torque gauge. The height and angle (x, y, and z axes) of the digital torque gauge and implant handpiece were adjusted through a jig for passive connection. The experiment was conducted under the setting torque value of 35 Ncm (implant placement torque) and 50 Ncm (overloading torque condition) and 30 times per set; a total of 5 sets were performed (N = 150).For statistical analysis, the difference between the groups was analyzed using the Mann–Whitney U test and the Friedman test was used to confirm the change in output torque (α=.05). Results: NSK and SAESHIN implant handpieces showed significant differences in output torque results at the setting torques of 35 Ncm and 50 Ncm (P <.001). The type of implant handpiece and repeated use influenced the output torque (P <.001). Conclusion . There may be a difference between the setting torque and actual output torque due to repeated use, and the implant handpiece should be managed and repaired during long-term use. In addition, for successful implant results in dental clinics, the output torque of the implant handpiece system should be checked before implant placement.

Cecal diverticulitis is a rare entity and remains a difficult diagnostic problem. Most patients are presented with an acute pain in the abdomen, which is nearly indistinguishable from that of appendicitis. Preoperative diagnostic studies are not helpful. Even with an operation, the correct diagnosis may be difficult to predict with certainty. The differential diagnosis between a cecal malignant tumor and a mass caused by inflammation due to cecal diverticulitis is difficult. Suspicion of a neoplastic process continues to prompt colectomy in an emergency setting. If diagnosed preoperatively, it can be treated effectively with a broad spectruum of antibiotics without surgical intervention. The physician must be aware this condition and be prepared to choose the most apropriate treatmetn. A case was experienced involving of solitary cecal diverticulitis misdiagnosed as a cecal tumor in a 61-year-o0ld female. This unique form of diverticulitis is herein reported with literature review.

PURPOSE: Because of an improving gastric cancer detection program and treatment methods, we can expect improved survival of patients with gastric cancer. Given the longer survival times, the chance of an occurrence of multiple primary malignant tumors other than stomach is increased in the same patients. The purpose of this study is to analyze the clinical characteristrics and the survival of patients with gastric cancer and other malignancies. MATENRIALS AND METHODS: A retrospective study of 3669 patients with gastric cancer observed at our department between January 1994 to December 2002 was conducted. Associated tumors were diagnosed using the Warren and Gates criteria, and included tumors that were not considered to be a metastasis, invasion, or recurrence of the gastric cancer. RESULTS: Of all 3669 patients, 2.07% (n=76) had primary tumors other than gastric cancer, 63% of which were synchronous (n=48) and 37% metachronous (n=28). The mean age of the study group was 64.9 (65.5 in males, 61.8 in females), and the male-to-female ratio was 4.8 : 1. The most common cancer associated with gastric cancer was a hepatocellular carcinoma (23.7%), followed by colorectal cancer (17.1%), esophageal cancer (10.5%), breast cancer (6.6%). Of the 45 patients who had undergone a resection, 14 were in stage I, 12 in stage II, 13 in stage III, and 6 in stage IV. No statistically significant differences were found between the synchronous and the metachronous groups with regard to age, sex ratio, differentiation, and stage. The 5-year survival rates of the metachronous and the resected patients were significantly higher than those of the synchronous and the non resected patients, respectively. CONCLUSION: Due to increasing length of the follow-up period for patients with gastric cancer, another malignancy may develop in other organs. Therefore, physicians should pay attention to detect other cancers early in these patients, and a surgical resection is recommended as the treatment of choice in the management of multiple primary cancer associated with gastric cancer.

The infection status of Clonorchis sinensis metacercariae (CsMc) was examined in freshwater fish from a highly prevalent site, Wicheon (a branch of Nakdong-gang), which is located in Gunwi-gun, Gyeongsangbuk-do, the Republic of Korea. Total 1,162 fish in 32 species were examined by the artificial digestion method through 6 years. CsMc were detected in 720 (67.5%) out of 1,067 fish (26 spp.) and their density was 610 per fish infected. In the susceptible gobioninid fish group, i.e., Pungtungia herzi, Squalidus gracilis majimae, Squalidus japonicus coreanus, Sarcocheilichthys variegatus wakiyae and Pseudorasbora parva, all of 323 fish were infected with an average of 1,310 CsMc. Total 23 (95.8%) gobioninid fish, i.e., Pseudogobio esocinus, Abbottina springeri, Hemibarbus longirostris, Microphysogobio koreensis, and Microphysogobio jeoni, were infected with 127 CsMc in average. In the acheilognathinid fish (bitterlings) group, the prevalence was 77.0%, and the density was 50 CsMc per fish infected. In the rasborinid fish (chubs) group, i.e., Zacco platypus, Zacco temminckii, Zacco koreanus, and Opsariichthys uncirostris amurensis, 147 (36.5%) out of 403 fish examined were infected with 15 CsMc in average. The susceptibility indices of CsMc were 412 in the overall positive fish group, 1,310 in the gobioninid group-1, 122 in the gobioninid group-2, 38.5 in the acheilognathinid group, and 5.5 in the rasborinid fish group. Conclusively, it was confirmed that CsMc are highly prevalent in fish from Wicheon, and their infection tendency varied according to the subfamily groups in Cyprinidae fish hosts.

Pneumonia and meningitis are the most frequent manifestations of pneumococcal infections. Pneumococcal spinal epidural abscesses have been rarely reported. Spinal epidural abscess by Streptococcus pneumoniae has been diagnosed among the patients with diabetes mellitus, alcoholism, corticosteroid therapy, intravenous drug use, chronic renal failure, AIDS, and history of spinal surgery. Recently, we experienced a case of pneumococcal spinal epidural abscess after spinal trauma. A 36-year-old male patient was admitted with back pain, fever, and paraplegia which occurred 5 days after the trauma. Spine MRI revealed spinal epidural abscess at the level from T2 to T9. He was treated with antimicrobial agents and surgical exploration for spinal epidural abscess. Pus culture grew S. pneumoniae which was susceptible to penicillin. Despite early surgical treatment, neurologic sequelae remained. Considering the high mortality and morbidity of pneumococcal spinal epidural abscess, early diagnosis and aggressive treatment including surgical intervention and antibiotics therapy should be implemented immediately.
