Histopathological and Neurobehavioral Characterization in Adult Mice Exposed to Traumatic Brain Injury

PURPOSE: Traumatic brain injury (TBI) is a significant cause of morbidity and mortality worldwide. Severity of the initial insult is one of the most significant factors affecting outcome following TBI. In order to investigate the mechanisms of cellular injury and develop novel therapeutic strategies for TBI, we designed a standardized animal TBI model and evaluated histological and functional outcomes according to the degree of impact severity. METHODS: Male adult C57Bl/6 mice underwent controlled cortical impact (CCI) at varying depths of deflection (1.0-2.0 mm). We performed hematoxylin and eosin staining at 7 days after recovery from TBI. Neurobehavioral characterization after TBI was analyzed by the Barnes maze test, passive avoidance test, open field test, rotarod test, tail suspension test, and light/dark test. RESULTS: We observed a graded injury response according to the degree of deflection depths tested (diameter, 3 mm; velocity, 3 m/s; and duration, 500 ms) compared to sham controls. In the Barnes maze test, the severe TBI (2 mm depth) group showed reduced spatial memory as compared with the sham and mild TBI (1 mm depth) groups at 7 days after TBI. There was a significant difference in the results of the open field test and light/dark test among the three groups. CONCLUSION: Our findings demonstrate that the graded injury responses following TBI resulted in differential histopathological and behavioral outcomes in a mouse experimental CCI model. Thus, a model of CCI with histologic/behavioral outcome analysis may offer a reliable and convenient design for preclinical TBI research involving mice.

Study of a "wing-type" implant on stress distribution and bone resorption at the alveolar crest

OBJECTIVES: Implants connect the internal body to its external structure, and is mainly supported by alveolar bone. Stable osseointegration is therefore required when implants are inserted into bone to retain structural integrity. In this paper, we present an implant with a "wing" design on its area. This type of implant improved stress distribution patterns and promoted changes in bone remodeling. MATERIALS AND METHODS: Finite element analysis was performed on two types of implants. One implant was designed to have wings on its cervical area, and the other was a general root form type. On each implant, tensile and compressive forces (30 N/m2, 35 N/m2, 40 N/m2, and 45 N/m2) were loaded in the vertical direction. Stress distribution and displacement were subsequently measured. RESULTS: The maximum stresses measured for the compressive forces of the wing-type implant were 21.5979 N/m2, 25.1974 N/m2, 29.7971 N/m2, and 32.3967 N/m2 when 30 N/m2, 35 N/m2, 40 N/m2, and 45 N/m2 were loaded, respectively. The maximum stresses measured for the root form type were 23.0442 N/m2, 26.9950 N/m2, 30.7257 N/m2, and 34.5584 N/m2 when 30 N/m2, 35 N/m2, 40 N/m2, and 45 N/m2 were loaded, respectively. Thus, the maximum stresses measured for the tensile force of the root form implant were significantly higher (about three times greater) than the wing-type implant. The displacement of each implant showed no significant difference. Modifying the design of cervical implants improves the strength of bone structure surrounding these implants. In this study, we used the wing-type cervical design to reduce both compressive and tensile distribution forces loaded onto the surrounding structures. In future studies, we will optimize implant length and placement to improve results. CONCLUSION: 1. Changing the cervical design of implants improves stress distribution to the surrounding bone. 2. The wing-type implant yielded better results, in terms of stress distribution, than the former root-type implant.

Participants who were in the experimental group received either face-to-face or phone "Hospice Smart Patient" Service at least once a week for 5 months. RESULTS: There was a significant difference in quality of life and communication skill between the two groups after the service was provided. In addition, participants in experimental group showed improved decision making skills, mastery sense, and understanding of hospice and palliative care, which would be beneficial in improving their quality of life. CONCLUSION: We have concluded that the "Hospice Smart Patient" Program is useful for cancer patients in decision making, improving self-control and choosing hospice care to improve their quality of life.

Tamsulosin Monotherapy versus Combination Therapy with Antibiotics or Anti-Inflammatory Agents in the Treatment of Chronic Pelvic Pain Syndrome / 대한배뇨장애요실금학회지

PURPOSE: Chronic pelvic pain syndrome (CPPS) is treated by use of various protocols. We compared tamsulosin monotherapy with tamsulosin in combination with antibiotics or anti-inflammatory agents and evaluated the efficacy of these treatments in patients with CPPS. METHODS: Patients (n=107) who were younger than 55 years and diagnosed with CPPS were randomly assigned to treatment with tamsulosin at 0.2 mg (group A), tamsulosin at 0.2 mg plus anti-inflammatory drugs (group B) or tamsulosin at 0.2 mg plus antibiotics (group C) daily. We applied the National Institutes of Health-Chronic Prostatitis Symptom Index (NIH-CPSI) and the International Prostate Symptom Score (IPSS) to evaluate 100 patients who were treated for 12 weeks (7 withdrew). Scores of the three groups were compared by analysis of variance and we also evaluated subscores, which included pain, voiding and quality of life (QoL). RESULTS: All three groups showed statistically significant decreases in NIH-CPSI score, IPSS and subscore scores (P<0.05). There were no statistically significant differences between the groups except for the QoL domain of the IPSS (group A vs. C; P<0.01). CONCLUSIONS: Tamsulosin monotherapy for 12 weeks was effective for treating patients with CPPS, compared with combination therapy with antibiotics or anti-inflammatory drugs.

The experimental group participated in 8 weeks of TCE which included one day of exercise with instructor on site and 3 days of self-exercise at home guided by a videotape. RESULTS: The 8 weeks of TCE were found to be significantly effective in enhancing strength of low extremities, flexibility of ankles and shoulders, time of tandem stand with eye closed and level on the K-MMSE (Korean mini mental state examination). CONCLUSION: These results suggest that TCE has positive effects on physical fitness and cognition in patients with PD. Research over an extended period with the TCE intervention is recommended to identify further effects.

Prediction of Optimal Gluteal Intramuscular Needle Length by Skinfold Thickness Measurements in Korean Adults

PURPOSE: This study was conducted to assess optimal needle length for gluteal intramuscular injections (IM) via simple skinfold thickness (SFT). METHODS: For this study, 190 healthy adults were recruited and grouped into eight groups according to gender and body mass index (BMI) (kg/m2). The Korean Society for the Study of Obesity criteria defines a BMI under 20 as underweight, 20.1-22.9 as normal, 23-24.9 as overweight and over 25 as obese. For each participant, the SFT of dorsoguteal (DG) and ventrogluteal (VG) sites were measured using a caliper. Subcutaneous tissue thickness was acquired through ultrasonic images. RESULTS: For men in the overweight and obese groups at the DG site, for the obese group at the VG site, and for women in the normal weight, overweight and obese groups at both sites, the mean subcutaneous tissue thickness exceeded 1.84 cm, the minimal length for a 1 inch needle used for IM. At the DG site, optimal intramuscular needle length (OINL) was 1.4 times in women and 1.0 times in men compared to SFT. At the VG site, OINL was 1.3 times in women and 0.9 times in men compared to SFT. CONCLUSION: The results of this study suggest that SFT is a reliable index to determine optimal needle length with minimal effort prior to IM.

Urethrovaginal Fistula due to Behcet's Disease / 대한비뇨기과학회지

Behcet's disease is a multisystem disorder presented with recurrent oral and genital ulcerations as well as ocular involvement. The principal manifestations in the urinary system are glomerulonephritis, cystitis, epididymitis, orchitis, and genital ulcerations. Urethrovaginal fistula is an unusual complication. The primary lesion of the disease is a small vessel vasculitis with endothelial deposition of immunocomplexes, and consequent inflammatory and necrotizing process of the vascular wall. We experienced a 19-year-old woman with Behcet's disease, who had a large urethrovaginal fistula on the anterior vaginal wall. The size of fistula was 2x1cm. For this patient, we tried combining bulbocavernosus muscle and labial fat pad flap (Martius flap) urethral reconstruction. This operative method seemed to be safe and effective for the urethral defect with Behcet's disease.

The Usefulness of the UBC(TM)(Urinary Bladder Cancer) Test for Screening of Transitional Cell Carcinoma of the Bladder in Patients with Hematuria / 대한비뇨기과학회지

PURPOSE: A new quantitative tumor marker, based on the combined measurement of urinary fragments of cytokeratins 8 and 18, namely the urinary bladder cancer antigen(UBC(TM)) test, has been proposed for the detection of bladder transitional cell carcinoma(TCC). We evaluated the diagnostic efficacy of UBC(TM) test in comparison with that of urinary cytology to establish UBC(TM) test for the diagnosis of TCC. MATERIALS AND METHODS: One-hundred ninety-six patients with hematuria were included in this study. Forty patients were diagnosed histologically as TCC by transurethral resection or radical cystectomy(group A), while the others had various benign urinary tract conditions(group B). RESULTS: UBC(TM) levels were significantly different between groups A (1851.39+/-4627microgram/l) and B (19.28+/-107.03microgram/l) (p<0.001). Sensitivity for diagnosis of TCC was 89.7%(36/40) in UBC(TM) test and 45%(18/40) in cytology(p<0.05). Specificity for diagnosis of TCC was 84.6%(132/156) in UBC(TM) test and 100%(156/156) in cytology. UBC(TM) test was significantly more sensitive than cytology in stage Ta(85.7% vs. 0%, p<0.05), T1 tumors(89.4% vs. 31.5%, p<0.05), and in Grades 1(83.3% vs. 25%, p<0.05) and 2(90.4% vs. 52.3%, p<0.05) tumors. UBC(TM) test was more sensitive in higher Grade(83.3% in Grade 1, 90.4% in Grade 2 and 100% in Grade 3). CONCLUSIONS: In comparison with urinary cytology, UBC(TM) test could be a valuable marker for diagnosis of TCC in patients with early stage and low grade TCC. Therefore, UBC(TM) test in association with cytology may be useful as a screening test for TCC of the bladder.

Laparoscopic Radical Cystectomy with Extracorporeal Ileal Conduit Diversion / 대한비뇨기과학회지

Since January 2003, two male patients, 60 and 47 years old, with muscle-invasive, organ-confined, transitional cell carcinomas of the urinary bladder underwent laparoscopic radical cystoprostatectomy with extracorporeal ileal conduit urinary diversion (LRCEIC). The surgical time was 8.5 hours in the first patient and 10 hours in the second. The respective blood losses were 350 and 380ml. In the first patient, ambulation resumed on day 2, bowel sounds on day 3 and oral intake on day 4, with a hospital stay of 8 days. In the second patient, due to inadvertent rectal injury, which was discovered on day 3, ambulation, bowel sounds and oral intake could not be determined. A pathological examination revealed a pT1N0M0 transitional cell carcinoma of the bladder, with the surgical margins negative for cancer, in the first patient, and a pT3bN1M0, with the surgical margins positive for cancer, in the second. Immediate postoperative complications included rectal injury and ileus in the second patient. With further experience and refinement in the operative technique, it is believe that LRCEIC can be performed safely and efficaciously in selected muscle-invasive bladder cancers.
