Articular cartilage can be damaged by trauma or by progressive degradation caused by disease. Unfortunately, it has a extremely limited capacity for repair and regeneration. The use of joint prosthesis has revolutionized but remains limited in its use. To know the possibility of clinical application of clinical application of autogenous bone-articular graft in open complicated intraarticular fractures we studied the change of bone-articular cartilage defect in medial femoral condyle of rabbits and viability of autogenous bone-articular graft stored within abdominal wall of rabbits. The results were obtained as follows: 1. There was over 90% viability of subchondral bone after 10 days storage in the adbominal wall but the articular cartilage showed degenerative change about 40% after 5 days passed. 2. The bone-articular defect was replaced by undifferentiated mesenchymal tissue and fibrous tissue, postoperative 6 weeks later. 3. In implanted bone-articular cartilage graft at 3 days, the chondrocyte of basal cell layer in articular cartilage was relatively well preserved but in 7 days, transplanted articular cartilage graft showed almost necrotic chage. Most of subchondral bones were well healed with host bone without regard to duration of implantation.

Authors examined 40,000 minifilms(boys and girls each 10,000 in junior and senior high schools) which were taken for survey of pulmonary tuberculosis for junior and senior high school students and checked the prevalence of scoliosis. It was considered lateral curvature of spine more than 10 degrees as nonpostural scoliosis, which were analyzed prevalence rate, degree of curvature, distribution of size of curvature, pattern of curve and direction of curvature. Following results were obtained. 1. The overall prevalence rate was 1.56; male 1.38. and female 1.70%(Junior high school 1.06%, Senior high school 2.05%). 2. Scoliosis secondary due to bony abnormality was found in 5 cases. 3. The most common pattern of curvature was the thoracic curve. 4. In sihgle curve, right to left ratio was 1.7, especially senior high school girls had more right curve and junior high school boys had more left curve. 5. The prevalence of senior high school students was greater than that of junior high school students and the degree of curvature was also severe in senior high school students than in junior high school students.

Recently autogenous nerve graft was usually used for segmental defect of peripheal nerve injury. In case of inappropriate size or amount of donor nerve graft, there were many studies included nerve regeneration with special nerve conduit material. To compare the result of autogenous nerve graft with that of silicone tubing method in segmental defect of sciatic nerve, the experiments were carried out on adult rats with autogenous nerve graft on the left side and silicone tubing on the right side. The results were as follows; 1. Myelinated nerve fibers were larger in silicone tubing method than autogenous nerve graft at postop. 4 weeks. 2. There was no difference in nerve regeneration in both groups at postop. 12 weeks. 3. Some atrophic changes were showed in denervated muscles in both groups at postop. 4 weeks. Skeletal muscle changes between the two groups were meagre. 4. Perineural adhension was rare in silicone tubing group in contrast to autogenous nerve graft group. 5. Nerve Conduction Velocity was similar between autogenous nerve graft and silicone tubing method after 4 weeks postoperatively. In conclusion, this study suggests that silicone tubing can be useful method to repair the large nerve gaps and has a potential clinical utilization in large segmental nerve defect.

Bochdalek hernia through Bochdalek foramen, defect at the posterolateral side of the diaphragm is one of the congenital diaphragmatic hernias. It usually occurs in infants, but very rare in old age and also on the right side. We experienced the right-side Bochdalek hernia including kidney herniation in 68 years old man man ifested by hemoptysis. CT scan revealed diaphragmatic defect and herniated liver, colon and kidney. Thoracotomy was performed and the 10 cm-sized large defect was closed with patch. After then, the patient has been well without symptom.

Background:
s/Aims: The treatment landscape for hepatocellular carcinoma (HCC) has significantly evolved over the past decade. We aimed to analyze trends in treatment patterns for HCC using a nationwide claims database from the Korean Health Insurance Review and Assessment Service.
Methods:
This retrospective population-based cohort study analyzed 171,002 newly diagnosed HCC patients between 2008 and 2022. Etiologies and treatment modalities were categorized based on the ICD-10 codes and insurance data.
Results:
The annual incidence decreased from 11,814 in 2008 to 10,443 in 2022. However, patients aged ≥70 increased noticeably, with those aged ≥80 rising from 3.8% in 2008 to 13.1% in 2022. From 2008 to 2022, the predominant cause of hepatitis B virus decreased from 68.9% to 59.7%, whereas nonalcoholic fatty liver disease increased from 8.9% to 15.8%. The initial treatment trends shifted: surgical resection and systemic therapy increased from 12.2% to 21.3% and from 0.2% to 9.6%, whereas transarterial therapy decreased from 49.9% to 36.6%. Best supportive care decreased from 31.7% to 21.3%. In the subgroup analysis, laparoscopic resection rate increased from 10.6% to 60.6% among the surgical resections. Sorafenib initially accounted for 100%, lenvatinib peaked at 36.5% in 2021, and atezolizumab-bevacizumab became the most widely used (63.1%) by 2022 among the systemic therapies.
Conclusions
This study demonstrates the temporal changes in the treatment patterns of Korean HCC patients. Surgical resection, particularly laparoscopic liver resection, and systemic therapy has increased significantly. These changes may have been influenced by reimbursement policies and advances in clinical research.
8.Clinical Features of Advanced Non-Small Cell Lung Cancer in Never-Smokers.
Korean Journal of Medicine 2011;80(4):427-433
BACKGROUND/AIMS: Smoking is major cause of lung cancer. However, the prevalence of lung cancer in never-smokers increasing recently. This study investigated the clinical characteristics of advanced lung cancer in never-smokers. METHODS: We anlyzed the clinical characteristics including demographics, bronchoscopic features, stage, and serum tumor markers, of never smokers with lung cancer seen at Kosin University Hospital from January 2001 to December 2008. RESULTS: There were 105 never smokers with lung cancer (mean age 61 years, 82 females), comprising 83 (79%) adenocarcinomas, 9 (8.6%) squamous carcinomas, and 13 (12.4%) undifferenciated carcinomas. The overall median survival time (MST) was 18.7 months. The MST was longer in females (21.6 vs. 13.7 months, p = 0.03), patients younger than 60 years (19.2 vs. 17.5 , p = 0.019), and those with adenocarcinoma (21.6 vs. 8.8 months, p = 0.038), and a neuron-specific enolase level of less than 15 ng/mL (22.4 vs. 13.4 months, p = 0.014). CONCLUSIONS: We analyzed the clinical characteristics of advanced lung cancer in never smokers. A more comprehensive study is need to compare never-smokers and smokers with lung cancer and to determine the appropriate treatment for non-smokers.

BACKGROUND: In general, the outcomes of arthroscopic repair for superior labrum anterior to posterior lesions (SLAP) are favorable, however, persistent pain and limitation of motion are not rare complications. One of the possible cause is a “knot-ache”. This study evaluated the results of reoperation of symptomatic recurrent SLAP lesions and asked whether the knot is associated with postoperative complications. METHODS: Between 2005 and 2015, a total of 11 patients who had undergone arthroscopic SLAP repair were reoperated for recurrent symptomatic SLAP lesion. By retrospective chart review, operative findings, the visual analogue scale for pain (pVAS), the range of motion (ROM), and functional scores were analyzed. RESULTS: The mean age of the study participants was 38.3 years, and the mean follow-up period was 42.5 months. In the primary operation, there were nine cases of repairs with conventional knot-tying anchors and three cases with knotless anchors. Impingement of the knots during abduction and external rotation of the shoulder was observed in the all cases with knot-tying anchors. The mean pVAS, ROM, and functional scores significantly improved with reoperation. At the final follow-up, the mean satisfaction VAS was 8.3. CONCLUSIONS: The knots of suture anchor maybe a possible etiology of the pain, which we termed a “knot-ache”. Considering that reoperation is performed due to pain after primary repair, the use of knotless suture anchor may have benefits of eliminating one of possible cause, “knot-ache”. Therefore, authors suggest the use of knotless anchors during reoperation for recurrent or recalcitrant pain after primary SLAP repair.

The Kallmanns syndrome is the most common form of isolated hypogonadotropic hypogonadism in which anosmia or hyposmia resulting from agenesis of hypoplasia of the olfactory lobes is associated with LHRH deficiency, This syndrome is genetically heterogeneous and can be trans-mitted as an X-linked, autosomal dominant or autosomal recessive trait. The hypogonadotropic hypogonadism results in absent or incomplete pubertal development and may be associated with anosmia or hyposmia, mid-line defect(color blindness, cleft-lip or
