A most common site for the isthmic spondylolisthesis is at fifth lumbar vertebra(L5) and far less at fourth(L4). The pathogenic lesion in the pars interarticularis is essentially the same in LA and L5 isthmic spondylolisthesis, but the clinical characteristics may differ each other according to their anatomical and biomechanical differences. A retrospective review of 24 patients of LA(study group) and 27 patients of L5(control group) isthmic spondylolisthesis was undertaken for their medical records and radiographs to compare the clinical characteristics in each groups. Included in each groups were all patients who were surgically treated during the same period and followed for more than two years after surgery. In the study group, 18 of 24 patients were females having an average age of 42.5 years(ranging 34-65), while in the control group, 17 of 27 patients were males having an average age of 38,1 years (ranging 13-59). The symptoms were severe leg pain in most of the study group, but in the control group, the leg pain and back pain were equally complained. The degrees of slip were similar in two groups, but a narrowing of dise space at slip segment was more prominent in study group. The lateral radiographs taken in flexion and extension revealed more changes of slip in study group (4.7mm in study group vs 2.8mm in control group in averages), and more angular motion at slip segment in study group unless the dise space is not severely narrowed. A spinal stenosis in CT findings was disclosed in almost all patients of study group and in 18 patients of control group. The sizes of L5 transeverse process were bigger than twice as those of L4 in 17(70.8%) patients including 9(37.5%) sacralizations of L5 in suty group, while in control group they were only 8(29.6%) patients with no sacralization. The heights of intercreastal line revealed no difference in two groups. The surgical procedures in study group were fusion only in two and decompression with fusion in 22(91.7%) patients and those in control group were fusion only in 11 and decompression with fusion in 16(59.3%) paticnts. The satisfactory results of treatment were in 21(87.5%) patients of study group and 25(92.6%) patients of control group without significant difference between two groups. In conclusion, the L4 spondylolytic spondylolisthesis compared to L5 lesion was more unstable and developed spinal stenosis more often. The surgical treatment and decompression procedure were also more needed in L4 lesions particularly in agend women.

Objectives: This study aimed to compare social decision-making between healthy controls and methamphetamine users using ultimatum game (UG) and dictator game (DG). In addition, the purpose of this study was to identify the effect of personality factors on social decision-making. Methods: The study included 39 methamphetamine users from a drug abuse center and a probation office, as well as 46 individuals in the control group. The UG and DG were conducted, where participants played the roles of proposers and responders. Also The Korean version of the Personality Factor Scale was used to assess personality factors among methamphetamine users. Results: The results showed that methamphetamine users had significantly lower acceptance rates compared to the control group in all proposed ratios in the UG. Additionally, the proposed amount of money (South Korean Won, KRW) in the DG were higher for methamphetamine users when the proposer had a happy facial expression and lower when the proposer had an angry facial expression. In addition, methamphtetamine users, who are more neurotic, had lower acceptance rates, but offeres more money when acting as the proposer. Conclusions The findings suggest that methamphetamine users exhibit lower acceptance rates in social decision-making tasks, indicating a conflict between self-interest and rejecting unfair offers. The study highlights the importance of considering social decision-making in the treatment and rehabilitation of methamphetamine users to address social maladjustment factors.

Compression of the left renal vein (LRV) between the superior mesenteric artery and the aorta has been termed the nutcracker syndrome. The entrapment of the left renal vein is not easily detectable by ordinary diagnostic procedures. We report 2 cases of the nutcracker syndrome with symptoms ( / ) diagnosed by phlebography and pressure measurement. In both cases, no remarkable findings were obtained from medical history and physical examination. Profuse collaterals from a left renal vein in one case with no symptom were observed in venous phase of renal angiography. In the other case, recurrent left flank pain and microscopic hematuria developed. In both cases, the diagnosis of "nutcracker phenomenon" was presumed by renal venography with measurement of pressure gradient between left renal vein and inferior vena cava. Awareness of the pathophysiology of the nutcracker syndrome ensures an early diagnosis. New diagnostic modalities are demanded for atypical cases.

Cervical pregnancy is a rare form of ectopic gestation in which the blastocyst implants in the cervical mucosa below the histologic cervical os. Because of the serious vaginal bleeding, hysterectomy was usually done in the management of cervical pregnancy. Howerver, conservative treatment is desirable for women who want to be pregnancy in the future. Methotrexate has been utilized recently for conservative management of cervical pregnancy. We report a case of cervical pregnancy which was treated succesfully with intramuscular methotrexate injection.

PURPOSE: In epidemiological studies, there are various associations of androgen receptor (AR) CAG with several diseases or phenotypes. However, the relationship between CAG repeat length and metabolic syndrome (MS) remains unclear, especially in Asian populations. This study was designed to evaluate the relationship between AR CAG repeat length polymorphism and MS in a Korean male population. MATERIALS AND METHODS: We explored the relationship between AR CAG repeat length polymorphism and MS in a Korean male population (n=337) from 2013 to 2014. AR CAG repeat were determined by microsatellite fragment sizing. Components of MS and laboratory data (lipid profile, fasting glucose, and glycated hemoglobin (HbA1c)) were analyzed with AR CAG repeat length. RESULTS: The mean AR CAG repeat length was 22.3±4.7. Sixty-nine men (20.5%) were diagnosed with MS. Men with MS showed significantly longer AR CAG repeat lengths compared with men without MS (26.2 vs. 21.4, p < 0.001). With increasing CAG repeat, the number of components meeting the NCEP criteria increased significantly. AR CAG repeat length was associated significantly with high density lipoprotein (HDL), triglyceride, and HbA1c levels. In the multivariate analysis, CAG repeat length, waist circumference, and levels of HDL were independently associated with MS. (odds ratio (OR)=1.37, 1.19 and 0.90, p < 0.001, 0.045, and 0.001, respectively). CONCLUSIONS: AR CAG repeat length was associated with MS and laboratory test results, such as those for HDL, triglycerides, and HbA1c, in Korean males. Longer CAG repeat length was identified as a risk factor for MS in Korean males.
