We studied the natural history of asymptomatic early avascular necrosis of the femoral head in forty-three patients(forty-three hips) who had been treated with arthroplasty due to progressed avascular necrosis of femoral head but had no symptoms in the other side. All initial lesions were classified with Ficat staging and International classification(ARCO). The duration until symptom onset and radiologic evidence of disease progression were evaluated. The average follow up period was over 37 months. Among forty-three hips, twenty-nine cases(67.4%) remained asymptomatic until last follow up but fourteen cases(32.6%) were symptomatic during the follow up, and twenty-six cases(60.5%) did not progress on the radiography but seventeen cases(39.5%) progressed to Ficat stage 3 or 4. Fifteen cases of IA, IIA, IB-cental and II B-central without lateral lesion did not occur symptom and didnt progress to Ficat stage 3 or 4 over a period of average 47 months(24-71 months). But fourteen cases of IB, IC, g B and II C progressed to Ficat stage 3 or 4 and they were all lateral lesion. These results suggest careful observation only can be done in the case of small involvement(less than 15%) and medial or central lesion relatively over a long period of time but for the large involvement(more than 30%) and especially lateral lesion, aggressive surgical treatment may be considered even though the early stage of disease for the prevention of progression. However it will need more period of time to accurately compare the results of various methods of treatment.

Badminton is a popular sport in Korea. However, medical records about badminton injuries are rare. Compared to other sports, badminton is of low risk, and most injuries related to badminton are overused injuries and are localized to the food and ankle. The frequent ones are medial/lateral epicondylitis, shoulder impingement syndrome, Achilles tendinitis, infra patellar tendinitis, hip bursitis, and spondylolysis/spondylolisthesis etc. The rehabilitation program include control of pain and swelling; restoring the full range of motion; increasing muscular strength, endurance and power; reestablishing neuromuscular control; improving balance; maintaining cardiorespiratory fitness; and incorporating functional progressions. The most important point in rehabilitation is regular follow-up during the healing process.

This sutdy was designed to localize the distribution of basic fibroblast growth factor(bFGF) in the developing rat condylar region and to elucidate the associated function of bFGF in the condyle development. The condyles of temporomandibular joint of Sprague-Dawley rats (27g of weight) were used. The tissues were examined with electron microscope and immunohistochemical method. The results were as follows: 1. The developing condylar region are divided in to 5 zones apparently: proliferative, maturation, hypertrophic, calcifying, and ossification zones. 2. The cells in the proliferative zone are condensed and have under-developed cell organells in the cytoplasm. This zone shows a strong immunoreactivity of bFGF. 3. The cells in the maturation zone are typical chondroblasts showing well-developed cell organells and round nucleus. The cartilaginous matrix does not show the immunoreactivity of bFGF, while the chondroblasts show the immunoreactivity. 4. The cells in the hypertrophic zone show hypertrophic change having the degenerated cell organelles and small nucleus. There are no immunoreactivity of bFGF in this zone except the nucleus and endoplasmic region showing mild immunoreactivity. 5, The cells in the calcifying zone show hypertrophic change and cell organelles are disappeared. The cells are surrounded by the calcified cartilaginous matrix. There are no immunoreactivity of bFGF in this zone except the endoplasmic region showing mild immunoreactivity. 6. In the zone of bone formation, chondroblasts are disappeared. Newly differentiated osteoblasts secreting osteoid around the calcified cartilaginous matrix. The bone marrow shows the immunoreactivity of bFGF, while the bone matrix does not show the immunoreactivity of bFGF.

Dural metastasis associated with chronic subdural hematoma is very rare in patients with malignant neoplasms; it may be difficult to distinguish malignant neoplasms from chronic subdural hematoma. Chronic subdural hematoma is usually a late manifestation of malignant tumors, which contributes to the severity of the prognosis. The scans obtained by using magnetic resonance imaging or computed tomography may be misleading when a subdural hematoma masks the underlying tumor. Herein, we report a case of a subdural hematoma with dural metastasis of unknown origin in a 45-year-old woman; however, the neoplasm was not detected until autopsy.

We report a rare case of primary glomerular disease with both features of IgA nephropathy and membranous glomerulonephritis in a 27 year-old woman with nephrotic syndrome. Histologically, glomeruli showed slight mesangial expansion, proliferation of mesangial cells, and short subepithelial spikes on capillary wall. Direct immunofluorescence demonstrated granular IgG and C3 deposits along the capillary walls, and IgA with C3 deposits in mesangium. Granular subepithelial and rnesangial deposits were observed by electron microscopy. The patient showed complete remission after 6 months therapy with steroid and ACE inhibitor.

OBJECTIVE: To evaluate the effects of local triamcinolone (TAC) injection and weight bearing on healing process of the injured Achilles tendon. METHOD: The right Achilles tendons in 54 rats, Sprague-Dawley (about 200 g), were each sutured after transection and allocated into three groups according to the amount of the local injection of TAC (none, 0.25 mg, and 1.25 mg respectively), and subsequently each group divided into three subgroups by the type of weight bearing {normal weight bearing (NWB), treadmill exercise (7-8 m/min, 10 min/day) from day 7 for 7 days, and hind limb immobilization respectively}. On 15th day rats were sacrificed, and then diameters of both injured and uninjured tendon, numbers of fibroblasts on injured tissues and he percentage of matured fibroblasts by microscopy were evaluated. RESULTS: The diameter of the hypertrophied neotendon in groups injected with TAC 1.25 mg was significantly decreased, but not in the others. There were no differences in numbers of fibroblast. As the amount of TAC increased in groups done with NWB and treadmill exercise, the percentages of matured fibroblasts significantly decreased. CONCLUSION: The local TAC injection on acute tendon injuries had deleterious effects on healing process of tendon, and follow-up study about the types of weight bearing is needed.

The Department of Dermatology at Kyungpook National University School of Medicine, initially the Dermatology Department of the Private Daegu Medical Training School in 1924, commemorated its 100th anniversary in 2023.Throughout its rich history, the department has been dedicated to advancing contemporary dermatology and enhancing the well-being of local communities through exceptional research, education, and social contributions.Initially tasked with the diagnosis, treatment, and education of patients with dermatological and urological disorders, the department evolved over time. In 1958, it separated from the Urology Department to focus solely on the diagnosis, research, and education of dermatological disorders. In 1962, Dr. Soon Bong Suh became the inaugural Chief of the Dermatology Department, marking the foundation of the Kyungpook National University School of Medicine’s Dermatology Department. Our legacy of pioneering contributions extends to dermatophytic diseases, which account for a large proportion of skin disorders in Korea, where we have excelled in basic research and treatment. These achievements have played a crucial role in the advancement of dermatophytic diseases.Subsequently, we have demonstrated expertise in blistering diseases and dermatopathology, making substantial contributions to the diagnosis and treatment of refractory skin conditions. Recently, we have been at the forefront of research and interventions for chronic inflammatory skin conditions that cause significant distress in many individuals, including atopic dermatitis and psoriasis. Our influence has also extended to severe and refractory skin disorders, including skin cancer and vascular anomalies. Striving to stay contemporary, our achievements now encompass aesthetics, including acne, pigmentation, and laser treatments. Our accomplishments have garnered widespread recognition nationwide, engendering high expectations for future advancements.
