We report one case of aseptic necrosis of both talus which has developed without any evidence of previous trauma. Aseptic necrosis of the talus is known to occur after any trauma which result in iterruption the blood supply to talus. Atraumatic aseptic necrosis of talus is extremely rarre condition. Some cases of atraumatic aseptic necrosis of talus were repoted by some authers, in whom Garcia described the first case in 1928. Most of the reported atraumatic aseptic necrosis were due to long term steroid therapy for unrelated medical problems and others were related to Alcoholism, Sepsis and Tuber culosis. ln this case we think for it may be caused or contributed by steroid therapy.

This study was conducted to evaluate prevalence of intestinal helminthic infections and skin tests and Paragonimus and Clonorchis in tuberculosis(TB) patients in Korea. Stool examinations by formalin-ether technique and intradermal tests were carried out in 2 areas; Masan TB hospital and Kong-Ju TB hospital. The positive rate of intestinal helminths of any kind was 51.7 percent among 329 patients in Masan hospital, but 18.1 percent among 215 patients in Kong-Ju hospital. The infection rates of Trichocephalus trichiurus and Clonorchis sinensis were 20.7 percent and 17.6 percent respectively in Masan hospital patients, but the infection rates of T. trichiurus and C. sinensis were 6.5 percent and 6.0 percent respectively in Kong-Ju hospital patients. In skin tests, positive reactions to Paragonimus and Clonorchis antigens were 22.0 percent and 37.6 percent respectively in Masan hospital patients. On the contrary, Kong-Ju hospital patients showed the positive rates of 15.2 percent for Paragonimus and 27.2 percent for Clonorchis respectively.

BACKGROUND:Acute vestibular neuronitis is the disease of which the etiology and pathophysiology are largely unknown . But the viral infection and ischemia of the labyrinth and the vestibular nerve are considered as general etiology. This study was performed to support the viral infection rather than the ischemic theory. MATERIALS & METHODS:We studied seventy years old female patient who showed painful vesicles on left auricle and vertigo with spontaneous nystagmus to the right side. We performed physical examination, serologic test, ENG test, pure tone audiogram, brain magnetic resonance imaging and polymerase chain reaction. RESULTS:We found small vesicles and vascular injection in left EAC, herpes zoster IgG positive, spontaneous right beating in electronystagmograpy, 54% left canal paresis in Caloric test , decreasing left side Tc in velocity step rotatory test, decresed gain, deviation to left in symmetry and phase lead in sinusoidal harmonic acceleration test, normal range hearing in pure tone audiogram, microangiopathy on cortex in brain MRI and negative PCR. CONCLUSION:This case supports viral infection etiology rather than ischemia in vestibular neuritis. But more studies to find the etiology of vestibular neuronitis are required.

Our objective was to evaluate the clinical feasibility of spatial domain filtering as an alternative to additional image reconstruction using different kernels in CT. Kernels were grouped as H30 (head medium smooth), B30 (body medium smooth), S80 (special) and U95 (ultra sharp). Derived from thin collimated source images, four sets of images were generated using phantom kernels. MTF (50%, 10%, 2%) measured with H30 (3.25, 5.68, 7.45 lp/cm), B30 (3.84, 6.25, 7.72 lp/cm), S80 (4.69, 9.49, 12.34 lp/cm), and U95 (14.19, 20.31, 24.67 lp/cm). Spatial resolution for the U95 kernel (0.6 mm) was 33.3% greater than that of the H30 and B30 (0.8 mm) kernels. Initially scanned kernels images were rated for subjective image quality, using a five-point scale. Image scanned with a convolution kernel led to an increase in noise (U95), whereas the results for CT attenuation coefficient were comparable. CT images increase the diagnostic accuracy in head (H30), abdomen (B30), temporal bone and lung (U95) kernels may be controlled by adjusting CT various algorithms, which should be adjusted to take into account the kernels of the CT undergoing the examination.

PURPOSE: This study was conducted to determine the effects of a fall prevention program on falls, physical function, psychological function, and home environmental safety in frail elders living at home in rural communities. METHODS: The design of this study was a nonequivalent control group pre posttest design. The study was conducted from July to November, 2012 with 30 participants in the experimental group and 30 in the control group. Participants were registered at the public health center of E County. The prevention program on falls consisted of laughter therapy, exercise, foot care and education. The program was provided once a week for 8 weeks and each session lasted 80 minutes. RESULTS: The risk score for falls and depression in the experimental group decreased significantly compared with scores for the control group. Compliance with prevention behavior related to falls, knowledge score on falls, safety scores of home environment, physical balance, muscle strength of lower extremities, and self-efficacy for fall prevention significantly increased in the experimental group compared with the control group. CONCLUSION: These results suggest that the prevention program on falls is effective for the prevention of falls in frail elders living at home.

8.Pathogenesis and pathophysiology of COPD.
Korean Journal of Medicine 2009;77(4):383-400
Chronic obstructive pulmonary disease (COPD) is a slowly progressed disease characterized by chronic irreversible airway obstruction with increased airway resistance and loss of elastic recoil by lung parenchymal destruction. COPD is a leading cause of morbidity and mortality worldwide. COPD is defined as a preventable and treatable disease with some significant extrapulmonary effects that may contribute to the severity in individual patients. Pathological changes characteristic of COPD are found in the proximal airways, peripheral airways, lung parenchyma, and pulmonary vasculature, showing chronic inflammation, and structural changes resulting from repeated injury and repair mostly caused by inhaled cigarette smoke. This pathological changes lead to airway trapping and progressive airway limitation.

Surgical excision of the subcutaneous tissues, with or without skin excision in the axillary hair-bearing area, has been the treatment of choice for Treating axillary a osmidrosis for the several decades. However, long periods of postoperative immobilization of a shoulder joint, partial necrosis of skin flaps or hematoma and the possibility of unsightly scars are frequent complications. For the purpose of reducing these complications, we performed ultrasonic aspiration of subcutaneous fat of the axilla, including the apocrine gland, using ultrasonic liposuction technique under confirmation of endoscopy via one small skin incision. From November 1997 to December 1998, a total of 134 patients (93 women and 41 men) received surgery for bilateral axillary osmidrosis on an outpatient basis. Sixty patients were evaluated more than 6 months after surgery. Among these patients, 6patients complained of a persistent foul odor(10%). Five patients received secondary ultrasonic aspiration for persistent foul odor and were then cured. We concluded that our method has several advantages such as 1) preservation of skin flap vascularity for the prevention of flap necrosis and axillary hair, 2) minimal scarring and bleeding, 3) shorter operation time and postoperative immobilization of the shoulder joint, 4) increased patient comfort, and 5) a safer operative method for recurred cases as a secondary method.
