PURPOSE: The purpose of this study was to identify changes in knee muscle strength after reconstruction of the anterior cruciate ligament (ACL) and the posterior cruciate ligament (PCL). METHODS: Thirteen subjects (males) with anterior ligament injury and ten subjects (males) with posterior ligament injury voluntarily participated in this study. Both groups were evaluated at the pre-and post-reconstruction stages using an isokinetic dynamometer. Peak torque, total work, and the hamstrings to quadriceps (H/Q) peak torque ratio were calculated at angular velocities of 60°/sec and 180°/sec. Statistical analysis was conducted on SPSS 18.0 for Windows using t-tests to compare mean differences. RESULTS: At an angular velocity of 60°/sec, both the ACL and PCL groups showed a significant increase in muscle strength in the flexors and extensors. Muscle strength in the extensors was significantly increased in the PCL group compared to the ACL group. At an angular velocity of 180°/sec, the ACL group showed a significant increase in muscle endurance in the flexors and extensors, and the PCL group showed a significant increase in muscle endurance in the flexors. At angular velocities of 60°/sec and 180°/sec, the H/Q peak torque ratio increased in the ACL group but decreased in the PCL group. Consequently, the H/Q peak torque ratio was significantly different for the two groups. CONCLUSION The results suggest that the patients with ACL injury should focus on strengthening the knee extensors and that the patients with PCL injury need to strengthen the knee flexors.

Purpose: This study aimed to compare the dose characteristics of the volumetric modulated arc therapy (VMAT) and dynamic conformal arc (DCA) techniques for metastatic brain tumor treatment using various indices to evaluate the quality of the plan and provide insights into the clinical implications of each approach. Methods: Twelve patients with single metastatic brain tumors treated with VMAT were retrospectively analyzed. For comparison with DCA, identical geometric parameters (excluding multileaf collimators) were applied. Dose coverage, normal tissue sparing, and treatment efficiencywere evaluated using indices such as CILIM98 , CIICRU , CIRTOG , QCRTOG , CISALT , HTCISALT , and CIPADDIC .These indices were statistically assessed to evaluate the differences between VMAT and DCA. Results: VMAT was superior to DCA in most indices for both small and large planning targetvolumes (PTVs). DCA plans for large PTVs showed a higher V12Gy , exceeding 10 mL and failing tomeet the recommended criteria (<10 mL). However, DCA required nearly half the monitor units(MUs) of VMAT, resulting in shorter treatment times. All indices, except for QCRTOG , demonstratedsignificant differences between VMAT and DCA. Conclusions Careful consideration is necessary for larger PTVs when deciding a plan becauseDCA can occasionally result in V12Gy of a brain minus PTV >10 mL. Conversely, DCA provides theadvantage of shorter treatment times because of its lower MU. This study highlights the importance of using a combination of indices to comprehensively assess treatment plan quality.

PURPOSE: Computed tomography (CT) has become popular in the diagnosis of acute pyelonephritis (APN) and its related complications in adults. The aim of this study was to investigate the relationship between uncommon CT findings and clinical and laboratory data in patients with APN. MATERIALS AND METHODS: From July 2009 to July 2012, CT findings and clinical data were collected from 125 female patients with APN. The six uncommon CT findings (excluding a wedge-shaped area of hypoperfusion in the renal parenchyma) studied were perirenal fat infiltration, ureteral wall edema, renal abscess formation, pelvic ascites, periportal edema, and renal scarring. The clinical parameters analyzed were the age and body mass index of the patients as well as the degree and duration of fever. Laboratory parameters related to inflammation and infection included white blood cell count, C-reactive protein (CRP) level, erythrocyte sedimentation rate, pyuria, and bacteriuria. RESULTS: The most common CT finding was perirenal fat infiltration (69 cases, 55%). A longer duration of fever, higher CRP level, and grade of pyuria were related with perirenal fat infiltration (p=0.010, p=0.003, and p=0.049, respectively). The CRP level was significantly higher in patients with renal abscess and ureteral wall edema (p=0.005 and p=0.015, respectively). CONCLUSIONS: The uncommon CT findings that were related to aggravated clinical and laboratory parameters of APN patients were perirenal fat infiltration, ureteral wall edema, and renal abscess formation. The inflammatory reaction and tissue destruction may be more aggressive in patients with these CT findings.

We report a case of combined off-pump coronary artery bypass grafting (OPCAB) and living-donor liver transplantation (LDLT). Patient was admitted to undergo liver transplantation due to Child C cirrhosis secondary to hepatitis B infection, and incidentally, his preoperative cardiac evaluation revealed silent ischemia due to the two-vessel coronary artery disease (CAD). Patient underwent OPCAB followed by LDLT. There was no perioperative cardiovascular event during the days of hospitalization. From the successful anesthetic experience of a combined OPCAB and LDLT, we cautiously suggest that a combined OPCAB and LDLT could be a surgical treatment for the patients with end-stage liver disease (ESLD) and advanced CAD.
