This study was carried out to observe the differences of bony pelvis between male and female Korean native goat by the pelvimetry. The results represented that the middle transverse diameter(1:1.35), ventral transverse diameter(1:1.12), transverse diameter of pelvic outlet(1:1.22), right oblique diameter(1:1.09), the width between ruber ischii(1:1.15) and width of pubis(1:1.11) were shown significant differences(p<0.01) between male and female Korean native goat.

A tail-on-detector (TOD) view has been used to see the symphysis pubis or sacrococcyx in skeletal scintigraphy, but it is inconvenient to acquire because a patient must sit or lean on a detector. The TOD views are still frequently performed in training hospitals in Korea, although it is becoming almost impossible to sit on a camera in this age of dual-headed cameras. The authors show cases with lateral views obtained in supine position that were acquired for the same reason; they are easier and more useful than the TOD views.

Desmoplastic fibroma is a rare primary tumor of bone that histologically and biologically mimics the extra-abdominal desmoid tumor of soft tissue. This report is dealt with two cases of desmoplastic fibroma occurring in a 22-year-old male, scapular lesion and 34-year-old male, pubic lesion. Radiologically, the tumors were lucent and expansile lesions. Histologically, they contained slender spindle cells and various amounts of collagen fibers. Radical excision was done on both cases and no recurrence was reported. Because of its rarity, we report two cases of desmoplastic fibroma.

Hemangiopericytoma is a rare tumor of blood vessels, first described and named by Stout and Murray in 1942, arising from the contractile, elongated cells which surround capillaries originated from the pericytes of Zimmermann. It can develop anywhere there are capillaries and mostly in the connective tissue of the human body. It can also develop at any age from 12 to 90 years old, and the rate of metastasis and prognosis vary with its histologic finding, We report three cases of hemangiopericytoma - one recurred in the right forearm where a tumor was excised 15 years ago, another occurred in the left pubis which metastasized to lung and head, the other metastasized from the lung to the right scapular area - treated at the department of orthopaedic surgery, Hanyang University Hospital from 1989 to 1995.

Pelvic bone is location with the worst prognosis in primary malignant bone tumor. Malignant bone tumor around symphysis pubis is extremely rare, and although small size, it is difficult to excise because of anatomical location. The authors report a case of intra-pelvic chondrosarcoma of the pubic bone with good functional result through resection by both superior & inferior pubic ramus osteotomy.

The purpose of our study was to determine the entrance surface dose and absorbed dose in ovary when using the metal speculum and plastic speculum in hysterosalpingography respectively. The examinations was performed in anthropomorphic phantom into which calibrated photoluminescence glass dosimeter were placed on symphysis pubis level surface and ovary area. We checked average fluoroscopy time and spot expose times during the hysterosalpingography. It was average fluoroscopy time 58 sec, spot expose 5 times. We divided the subjects into two different groups to used metal and plastic speculum. We measured 10 times of absorbed dose in the same condition of the anthropomorphic phantom. We compared two groups adsorbed dose on ovary with speculum material-related. The entrance surface dose on of plastic Speculum using group was average 17.23 mGy, absorbed dose on ovary was average 3.51 mGy. The entrance surface dose on ovary of metal Speculum using group was average 19.95 mGy, absorbed dose on ovary was average 4.14 mGy. Plastic speculum using group shows a decrease absorbed dose(17.9%) as compared with metal speculum using group. The method of plastic speculum using in hysterosalpingography. might provide us with lower radiation dose, especially in patients with childbearing stage.

A piezoelectric ultrasonic scaler, usually used to remove the tartar out of teeth and to amputate the pubis, is a recently popular instrument for dental treatment due to its several merits such as small size, low-electric power, precision and low-cost. It has typically two parts of a tip and vibration system, which is also composed of head, piezoelectric elements and tail-mass. The scaler concentrates its displacement on tip and has commonly a resonance frequency at 25~30 kHz, and in order to improve the performance of the scaler, it is important to standardize the size of the vibration system without tip for high performance because scaler in quality differs according to several tips. In this study, a Finite Element Analysis (FEA) was utilized to optimize the structure of ultrasonic scaler in the vibration system. Consequently, this study revealed that influence of several tips on property were minimized and scaler showed good property at the resonance frequency of 28 kHz.

We analyzed 320 clinical samples of parasitic infections submitted to the Department of Environmental Biology and Medical Parasitology, Hanyang University from January 2004 to June 2011. They consisted of 211 nematode infections, 64 trematode or cestode infections, 32 protozoan infections, and 13 infections with arthropods. The nematode infections included 67 cases of trichuriasis, 62 of anisakiasis (Anisakis sp. and Pseudoterranova decipiens), 40 of enterobiasis, and 24 of ascariasis, as well as other infections including strongyloidiasis, thelaziasis, loiasis, and hookworm infecions. Among the cestode or trematode infections, we observed 27 cases of diphyllobothriasis, 14 of sparganosis, 9 of clonorchiasis, and 5 of paragonimiasis together with a few cases of taeniasis saginata, cysticercosis cellulosae, hymenolepiasis, and echinostomiasis. The protozoan infections included 14 cases of malaria, 4 of cryptosporidiosis, and 3 of trichomoniasis, in addition to infections with Entamoeba histolytica, Entamoeba dispar, Entamoeba coli, Endolimax nana, Giardia lamblia, and Toxoplasma gondii. Among the arthropods, we detected 6 cases of Ixodes sp., 5 of Phthirus pubis, 1 of Sarcoptes scabiei, and 1 of fly larva. The results revealed that trichuriasis, anisakiasis, enterobiasis, and diphyllobothriasis were the most frequently found parasitosis among the clinical samples.

Purpose: Trochanteric pressure sores management has been improved through the development of musculocutaneous flaps. But it has many drawbacks such as donor site morbidity and functional muscle sacrifice. With the introduction of perforator flap, it is possible to use in every location where musculocutaneous perforators are present. We have reconstructed trochanteric pressure sores using perforator-based flaps from the ascending branch of lateral circumflex femoral artery. Methods: Between May of 2006 and April of 2008, we performed six cases of perforator-based flap from the ascending branch of lateral circumflex femoral artery for the coverage of trochanteric pressure sores. For identifying perforators, a line was drawn from the anterior superior iliac spine to the superolateral border of the patella as the vertical axis, from the pubis to the trochanteric prominence as the horizontal axis. In the lateral aspect of the intersection of these two axes, various flap were designed according to its defects. The flap was raised in the subcutaneous plane above the fascia and the pedicle was traced by doppler and identified. The pedicle was meticulously dissected not to injure the periadventitial tissues and transposed to the defect. The donor site was closed primarily. Results: The mean age of patients was 56.2 years. Four male and two female patients were studied. Five patients were paraplegic. The mean defect size was $6{\times}4\;cm$. The largest flap dimension was $14{\times}7\;cm$. Donor sites were closed primarily without any complications. All flaps survived completely without necrosis, hematoma or infection. There were no recurrence during the follow-up period. Conclusion: Trochanteric pressure sores using perforator-based flap from the ascending branch of lateral circumflex femoral artery can be performed safely and it would be a reliable option for coverage of trochanteric pressure sores with minimal donor site morbidity.
