Purpose: To evaluate the efficacy of the preventive abduction brace in dementia patients after bipolar hemiarthroplasty of the hip. Materials and Method: A review of 30 patients who had dementia prior to bipolar hemiarthroplasty of the hip. 20 females and 10 males were evaluated and their mean age was 80.4 years old (range, 68 to -92 years old). The average MMSE-K in dementia patients was 14.2 (range, 8 to 20). The reasons for the bipolar hemiarthroplasties were femoral neck fractures in all the cases. We analyzed the dislocation rates of those who had preventive abduction braces applied prospectively. Results: The average follow-up period after hemiarthroplasty was 2.2 years. All 30 patients had preventive abduction braces and no dislocations occurred after the bipolar hemiarthroplasties. Conclusion: Hip dislocations were not detected in those patients who preventive abduction braces applied. The present findings suggest that having a preventive abduction brace will definitely reduce the dislocation rate in dementia patients who have difficulties with rehabilitation after their operations.

BACKGROUND AND OBJECTIVES: Intracardiac pathology results in 15 - 20% of ischemic stroke, but transthoracic echocardiography (TTE) has a number of limitations because of suboptimal precordial windows or ultrasound interference with prosthetic materials. Transesophageal echocardiography (TEE) provides superior resolution of basal structures such as the left atrium, left atrial appendage, mitral valvular apparatus, atrial septum, and aorta. The purpose of this study was to describe the various TEE findings which were sources of cerebral emboli. MATERIALS AND METHOD: The study population was comprised of 122 patients (mean age:54.5, male 83, female 39) who were admitted to Severance Hospital because of ischemic stroke from 1991 to 1997. All patients underwent TEE with agitated saline contrast administration. Patients without a definitive cardiac source of embolism underwent Holtor monitoring, internal carotid and cerebral angiography, as well as transcranial Doppler. RESULTS: 1) The number of patients diagnosed as cardioembolic stroke was 55 (45.1%). Atrial fibrillation was noted in 31 patients of cardioembolic stroke and it was the most frequent finding. Among these patients, 16 did not have any other cardiac problem. 2) We were able to find the possible source of embolism in 49 (40.2%) patients with TEE. Among these patients, 12 did not have dysrhythmia or any known previous heart problem. We found spontaneous echo contrast in the left atrium and left atrial appendage in 33 cases. There were 8 patients who had intracardiac thrombus. Among these patients, 6 patients had thrombi in the left atrial appendage, 1 in left atrium and 1 in left ventricular apex. We found patent foramen ovale in 3 cases and atrial aneurysm in 1 case. We found atheromatous plaque and/or thrombi of the aorta in 16 cases, while there were 4 cases where lesions located in the ascending aorta and aortic arch and which were considered as the source of embolism. Small thrombi in the left atrial appendage and left atrium were only detectable with TEE. CONCLUSIONS: We described TEE findings in ischemic stroke patients. And we assert TEE is a useful diagnostic tool in detecting the source of cardioembolic stroke and it may be used as a primary diagnostic tool in patients who are being evaluated for ischemic stroke.

This study was performed to observe the present status of intestinal parasitic infections in a remote island, Yondo, located in southern part of Jeonranam-do(province), Korea. In February and May 1988, total 1,011 individual stool samples were collected and examined for intestinal helminths and protozoa using formalin-ether centrifugal sedimentation technique. The results are summarized as follows: Of 1,011 ingabitants examined, 398(39.4%) were positive for intestinal parasites. Helminth positives were 372(36.8%), and protozoan cyst positives were 56(5.5%). Ten species of parasites were found. Trichuris trichiura revealed the highest infection rate of 27.5%, Ascaris lumbricoides 17.4%, Taenia sp. 5.8%, Entamoeba coli 3.3%, Giardia lamblia 1.5%, Endolimax nana 0.8%, Hymenolepis nana 0.4%, hookworm 0.2%, Trichostrongylus orientalis 0.2%, and Entamoeba histolytica 0.2%, respectively. The female group showed higher positive rate (44.0%) than males (34.7%). Also, higher positive rates were observed among adults as compared with the group younger than 10 years old. Average value of E.P.G. was 1,876(range 200-17,800) in A. lumbricoides positives, and 327(range 200-1,600) in T. trichiura positive cases. In helminth egg positive cases, single infection was 63.4%, double infection 34.7%, and triple infection 1.9%, respectively. Among protozoan cyst positives, single infection was 94.6%, and double infection was 5.4%. The present study revealed that the prevalence of intestinal parasites among inhabitants in Yondo island is still so high that special control measures should be performed.

BACKGROUND AND OBJECTIVES: In rhinoplasty, it is essential to take photographs in order to make preoperative plans and postoperative evaluations. However, for Asians, standardized rules or important photographic points in taking pictures in rhinoplasty have not yet been established. The purpose of this study was to standardize photography in rhinoplasty. MATERIALS AND METHODS: Using a 35 mm single lens reflex camera with 105 mm macro lens, the authors took pitures of various postures, such as close-up frontals, close-up profiles, chin on chest views, as well as conventional postures such as frontal, profile, oblique, and basal. The Frankfort plane was utilized for all frontal and lateral views. The plane was kept horizontal and centered for all photographs. The vertical axis may be checked by aligning it with the midsaggital plane on the frontal view. The oblique photograph is standardized by ligning the tip of the nose with the outline of the cheek. A close up of the nose from frontal and profile views should include the eyebrow and the lips. RESULTS: A close-up frontal and chin on chest views gave more detailed information about the nasal dorsum and the width of alar flare. A close-up profile views were found to be the most suitable for evaluating the nasal tip. It was possible to evaluate preoperative and postoperative results objectively by using the standardized photographs described here. CONCLUSION: Preoperative and postoperative photographs are important in providing good results in rhinoplasty. The use of photographs can also provide grounds for objective comparisons between the works of different plastic surgeons. More studies are needed to complete photographic standardization and the present study contributes to this cause.

BACKGROUND: Rhinoplasty surgeons have a choice of several approaches to the nose. The approaches can conveniently be divided into external and intranasal techniques. We prefer the external approach to the intranasal approach because the former provides better operative fields and more complete correction. OBJECTIVES: The purpose of this report is to analyze the experiences of rhinoplasty through the external approach. MATERIALS AND METHODS: A retrospective study was performed in 119 patients who underwent rhinoplasty using the external approach from January of 1994 through March of 1997. RESULTS: This procedure has been used in all kinds of deformities even though most of them overlapped: 54 cases of crooked nose, 57 cases of saddle nose, 5 cases of hump nose and 3 cases of tip surgery. CONCLUSION: The exact procedures of cosmetic nasal tip surgery can be performed more easily by the external approach. The disadventages of this procedure, which is the columellar scar, longer operation time and post-operative edema, are neglible.

Purpose: This study aimed to compare the therapeutic effects of corticosteroid irrigations and normal saline irrigations in the early inflammatory state of the salivary gland. Materials and Methods: Adult male Wistar rats were divided into experimental (n=6) and control (n=3) groups. Inflammation was induced in the experimental subjects on both sides of the submandibular gland with ligation. After 14 days, both sides of the glands were de-ligated and retroductal irrigation using saline (n=3) and a corticosteroid (n=3) was performed on the left sides only. The controls (n=3) were used to normalize the gland state for the effects of diet and aging. Magnetic resonance imaging was performed to confirm inflammation and post-irrigation gland recovery by measuring relative signal intensity (SI). The glands were excised for histological examination. Results: All experimental animals showed inflamed glands with increased SI and subsequent recovery of the gland with decreased SI to varying degrees. The SI of the controls showed no significant changes during the overall period. The mean SI change of the irrigated gland was higher than that of the non-irrigated side, without a significant difference. The corticosteroid-irrigated glands showed a greater change in SI than that of the saline-irrigated glands. Histology revealed that inflammation was not observed in most of the irrigated glands, while mild to moderate quantities inflammatory cells were found in non-irrigated glands. Conclusion Corticosteroid irrigation mitigated the early stages of salivary gland inflammation more effectively than normal saline.
