Intraosseous ganglion is an uncommon benign tumor thought to be caused by an intramedullary metaplastic event. We recently experienced a case of intraosseous ganglion that occurred on the femoral head of a 65-year old man who complained of intermittent hip pain. Complete evaluation including bone scan, CT, MRI was done. His pain disappeared after curettage and bone graft was done on the lesion.

PURPOSE: Rectoceles are often associated with anorectal symptoms. Various surgical techniques have been described to repair rectoceles, but the surgical results vary. The aim of this study was to compare transanal repair (TAR) and transanal repair with posterior colporrhaphy (TAR+PC). METHODS: The records of 58 patients operated on during a 56-month period were reviewed. Of those 26 patients had a TAR, and 32 patients had a TAR+PC. Interviews and anorectal physiologic studies were performed preoperatively and postoperatively. RESULTS: The recurrence rate after a TAR+PC was lower than the recurrence rate after a TAR (TAR 19.2% vs. TAR+PC 3.1%). The rectal sensation (sensory threshold: TAR 64.8+/-18.9 ml vs. TAR+PC 56.1+/-23.67 ml; earliest defecation urge: TAR 116.4+/-29.5 ml vs. TAR+PC 104.8+/-31.2 ml) was more improved after a TAR+PC. CONCLUSIONS: A TAR+PC for treatment of a rectocele is safe and effectively corrects obstructed defecation. The improvement probably relates, at least in part, to rectal sensational factors other than the dimensions of the rectocele.

PURPOSE: Generally, the constipation is a medical disease, but recently, there are many reports showing the good results after correction of rectocele in constipated patients. The authors try to show the effect of surgery in rectocele cases and also analyse the relationship between the anatomical distortion and clinical symptoms by using anorectal physiologic study before and after operation. METHODS: 31 cases of rectocele are surgically corrected from June 1998 to August 2001. 31 cases of them could be followed up and with them, pre- and post-operative anal ultrasonography, anorectal manommetry and defecography were tried. Personal interview was also done to each patient. RESULTS: After trasanal rectocele repair, the rectocele size decreased and clinical symptoms improved remarkably. In defecography, anorectal angle (pre-op; 105.9+/-6.0 degrees vs. post-op; 109.5+/-3.7 degees) and perineal descent (1.6+/-0.7 cm vs. 2.4+/-1.2 cm) increase in pushing state after operation. In anorectal manometry, mean resting anal pressure (29.2+/- 3.4 mmHg vs. 17.9+/-4.6 mmHg) and maximal squeeze pressure (84.5+/-20.8 mmHg vs. 47.6+/-12.1 mmHg) decreased and rectal sensation improved after operation. CONCLUSIONS: Current results suggest that the surgical correction aims not only the decrement of the rectocele size but changing the vector power on pushing more physiologically and also improving the rectal sensibility.

Epidermoid cysts occur rarely on the palms and soles, where hair is not present. These cysts have long been assumed to arise from traumatic implantation of epidermal fragment, but the pathogenesis is still controversial. Recently, with microscopic findings, immunohistochemical features, and molecular studies, the epidermoid cysts of the sole may be induced by the human papillomavirus. We report two cases of epidermoid cysts of the sole with the discussion of the pathogenesis.

We described the findings of fine needle aspiration cytology of the lung from a patient with Wegener's granulomatosis. Early diagnosis and prompt treatment of the patients with Wegener's granulomatosis is essential for a better prognosis. However, the variety of clinical presentations and nonspecific radiologic infiltrates of Wegener's granulomatosis frequently make the diagnosis difficult. Although an open lung biopsy is required for a firm diagnosis, fine needle aspiration cytology & biopsy preparation can also provide an adequate tissue sample, when the findings of fine needle aspiration are considered with clinical manifestations and ANCA value in the serum. The cytologic smears showed scattered necrotic tissue fragments entrapping many neutrophils and occasional epithelioid cells. Multinucleated giant cells were infrequently observed. Ziehl-Neelsen stain for acid fast bacilli was negative. All the cytologic features recapitulated the histopathologic findings of purulent and necrotizing granulomatous inflammation seen in Wegener's granulomatosis.

9.High-spatial-resolution, instantaneous passive cavitation imaging with temporal resolution in histotripsy: a simulation study

Purpose:
In histotripsy, a shock wave is transmitted, and the resulting inertial bubble cavitation that disrupts tissue is used for treatment. Therefore, it is necessary to detect when cavitation occurs and track the position of cavitation occurrence using a new passive cavitation (PC) imaging method.
Methods:
An integrated PC image, which is constructed by collecting the focused signals at all times, does not provide information on when cavitation occurs and has poor spatial resolution. To solve this problem, we constructed instantaneous PC images by applying delay and sum beamforming at instantaneous time instants. By calculating instantaneous PC images at all data acquisition times, the proposed method can detect cavitation when it occurs by using the property that when signals from the cavitation are focused, their amplitude becomes large, and it can obtain a high-resolution PC image by masking out side lobes in the vicinity of cavitation.
Results:
Ultrasound image simulation confirmed that the proposed method has higher resolution than conventional integrated PC imaging and showed that it can determine the position and time of cavitation occurrence as well as the signal strength.
Conclusion
Since the proposed novel PC imaging method can detect each cavitation separately when the incidence of cavitations is low, it can be used to monitor the treatment process of shock wave therapy and histotripsy, in which cavitation is an important mechanism of treatment.

To elucidate some DNA adducts as a biological marker for workers of chromate pigment, the effects of chromium exposure on the formation of 8-hydroxydeoxyguanosine(8-OH-dG) and sister chromatid exchanges(SCEs) frequency in 38 workers of a pigment plant in Bucheon which utilized lead chromates, were examined. The chromium contents of venous blood and urine were measured as working environmental exposure level. The concentrations of 8-OH-dG in DNA isolated from lymphocytes were determined with high performance liquid chromatography and electrochemical detector and denoted as a molar ratio of 8-OH-dG to deoxyguanosine(dG). The SCEs frequency were analyzed in DNA isolated from lymphocytes. A significant correlation was found between creatinine adjusted urine chromium concentration and the molar ratio of 8-OH-dG to dG(r=0.47, p<0.01). After adjusting the current smoking habit, the correlation coefficient was increased(r=0.62, p<0.05). However, there was no significant correlation between the SCE frequency and chromium exposure. This significant results between molar ratio of 8-OH-dG to dG and chromium exposure are in good agreement with in vitro studies that support the importance of DNA adduct formation for the carcinogenic effect of chromium.
