PURPOSE: To assess the relationship between biochemical bone turnover marker and bone mineral density(BMD) and to evaluate the predictive role of biochemical bone marker in postmenopausal osteopenic woman. MATERIALS AND METHODS: Ninety two postmenopausal women (50-65 years old), who have the T-score from -1.0 to -2.5 by the dual-energy X-ray absorptiometry (DEXA), were examined consecutively with BMD of the lumbar spine and biochemical bone turnover marker including urine Cross-linked N-telopeptide of type I collagen (u-NTX), urine deoxy-pyridinoline (u-DPD), serum Cross-linked C-telopeptide of type I collagen (s-CTX), serum bone-specific alkaline phosphatase (s-BAP), serum osteocalcin (s-OC) for six months. We evaluated the relation between the changes in the biochemical markers and the rate of bone loss. RESULTS: Seventy four postmenopausal women completed this study. All biochemical bone turnover marker and BMD at one time point including the baseline and the end point did not show any significant correlation. Another longitudinal study found no significant correlation between the baseline biochemical bone turnover marker and the change in lumbar spine BMD. The other study showed significant correlation between the changes in s-CTX/s-OC and the change in lumbar spine BMD (p=0.04, 0.03). The changes of u-NTX and s-OC were larger in the group of aggravation in BMD (p=0.032, 0.041). CONCLUSION: The relationship between bone turnover marker and BMD at one time point was not clear. The predictive role of baseline bone turnover marker was limited to predict the magnitude of changes in lumbar BMD in untreated osteopenic individuals. The changes of s-OC showed significant predictive role in the bone loss in osteopenic postmenopausal women.

PURPOSE: Bony resection of the proximal medial tibia, an alternative technique for soft tissue balancing in total knee arthroplasty (TKA), was compared to the conventional medial soft tissue release technique. MATERIALS AND METHODS: From June 2005 to June 2007, we performed 40 TKA in 27 patients with > or =10degrees tibio-femoral varus deformity. The conventional, medial soft tissue release technique was applied in 20 cases and bony resection of proximal medial tibia in the other 20 cases (vertical osteotomy group). Total operation time, knee range of motion (ROM), hospital for special surgery (HSS) scores, and tibio-femoral medial-lateral gap ratio in 0degrees, 90degrees, and 130degrees flexion at postoperative 6 months were compared between the groups. RESULTS: The total operation time was shorter in the vertical osteotomy group. Tibio-femoral medial-lateral gap ratio in 130degrees flexion was closer to 1 in the vertical osteotomy group (p=0.000). There was no significant difference in the ROM, HSS score, or tibio-femoral medial-lateral gap ratio in 0degrees and 90degrees flexion at postoperative 6 months. CONCLUSIONS: In severe varus knees, bony resection of proximal medial tibia can be considered as an alternative technique, in order to decrease total operation time and to obtain medial-lateral, soft-tissue balance in deep flexion.

Gastric cavernous hemangioma is a relatively rare benign gastric disease. Gastric hemangiomas are most commonly encountered in adulthood, although they can occur in any age group. While surgical resection is the curative treatment, endoscopic resection can be performed for treatment of selected cases. The patient was a 53-year-old male who was referred for evaluation of incidentally detected gastric subepithelial tumor with dense vascularity and oozing on the apex of the lesion. An EUS revealed a homogenously hypoechoic mass confined to the submucosal layer that showed no continuity with adjacent vessels, and there was no regional lymphadenopathy. Endoscopic submucosal dissection was successfully performed with en bloc resection. The final diagnosis was benign cavernous hemangioma of the stomach.

BACKGROUND: Pulmonary artery banding (PAB)in the functional univentricular heart (UVH)is a palliative procedure for staging toward the Fontan procedure;however,it is known to be a risk factor. MATERIALS AND METHOD: The records of all 37 patients with functional UVHs who underwent surgical palliation using PAB between September 1989 and August 1999 were reviewed retrospectively.We investigated the aortic arch obstruction,the development and progression of subaortic stenosis after PAB,and risk factor of mortality according to surgical method. RESULT: In 37 neonates and infants with single ventricular physiology,aortic arch obstruction was combined in 7.There were 6 early deaths (16.2%)after PAB and 3 late deaths (8.1%)after Fontan operation.The actuarial overall survival including early mortality at 3 and 5 years were 8 0 .7+/-6.6%,72.2 +/-8.2% respectively. Among 31 patients who survived PAB,27 patients (87.1%)could become candidates for Fontan operation;22 patients(71.0%)completed Fontan operation with 3 deaths and 5 were waiting bidirectional cavopulmonary shunt(BCPS)or Fontan operation (follow-up mean 4.5 year,minimal 2 year). Subaortic stenosis developed in 8 patients after PAB (8/29,27.6%);3 cases in the patients without arch anomaly (3/22,13.6%)and 5 in those with arch anomal y (5/7,71.4%).The subaortic stenosis was managed with Damus-Kaye-Stansel procedure (DKS)in 6 patients without operative mortality and conal septum resection in 2 without long-term survivor. Analysis of risk factors established that aortic arch obstruction was strongly associated with subaortic stenosis (p<0.001).The only risk factor of late mortality was Fontan procedure without staged palliation by BCPS (p=0.001). CONCLUSION: PAB is effective as an initial palliative step in functional UVH.And the high risk group of patients with aortic obstruction can undergo effective short-term PAB as an initial palliative step,with subsequent DKS for subaortic stenosis.This strategy,initial PAB and careful surveillance,and early relief of subaortic stenosis can maintain acceptable anatomy and hemodynamics for later Fontan procedures.

Objective:
Microsurgical treatment could be a good alternative for the treatment of recurrent cerebral aneurysm after coil embolization. The purpose of this study was to present our experience of microsurgical treatment for recurrent cerebral aneurysm previously treated using coil embolization.
Methods:
From June 2012 to May 2019, 34 patients consecutively received microsurgical treatment for a recurrent cerebral aneurysm previously treated using coil embolization after it ruptured.
Results:
Of the 34 patients with aneurysm, 33 had the aneurysm located in the anterior circulation. The most common location was the anterior communicating artery (13 cases). Immediate radiologic outcome at coil embolization was completed (n=6), residual neck (n=26), and residual sac (n=2). The reason for microsurgical treatment included rebleeding (n=12), persistent residual sac (n=1), and recurrence on follow-up study (n=21). Rebleeding occurred within 10 days after coil embolization in 10 cases, and the other 2 were due to regrowth. In the 20 recurred and saccular aneurysms, coil compaction was present in 11 aneurysms and regrowth in 9 aneurysms. Simple neck clipping (n=29) and clipping with coil mass extraction (n=3) was possible in the saccular aneurysms. The blood blister like aneurysm (n=2) were treated using bypass and endovascular internal carotid artery trapping. In the follow-up study group after microsurgical treatment there were no severe complications due to the treatment. Age, cause of retreatment, and modified Rankin Scale before microsurgery were associated with good outcome (p<0.001).
Conclusions
Microsurgical treatment may be a viable and effective option for treating recurrent aneurysms previously treated by endovascular techniques.

BACKGROUND: The aims of this study are to verify the result of the surgical treatment of ALCAPA and to identify the postoperative changes of left ventricular dimensions and mitral regurgitation (MR). MATERIAL AND METHOD: Fifteen patients operated on since 1985 were included in the study. The patients operated on before 1998 (n=9) showed heterogeneous properties with various surgical strategies and cardiopulmonary bypass techniques. However, six patients were operated on with the established surgical strategy since 1998; 1) Dual perfusion and dual cardioplegic solution delivery through ascending aorta and main pulmonary artery, 2) Coronary transfer by rolled-conduit made of pulmonary artery wall flap, and 3) Additional mitral valvular procedure was not performed. RESULT: Median age of the study group was 6 months (1 month to 34 years). The operative methods were left subclavian artery to left coronary artery anastomosis in 1, simple ligation in 2, Takeuchi operation in 2, and coronary reimplantation in 10 pateints. The mean follow up period was 5.5<5.8 years (2 months 14 years). There were one early death (6.7%) and one late death. Overall 5-year survival rate was 85.6+/-9.6%. The Z-value of left ventricular end-diastolic and end-systolic dimensions were 6.4+/-3.0 and 5.1+/-3.6 preoperatively, and decreased to 1.7+/-1.9 and 0.8+/-1.6 in 3 months (p<0.05). Significant preoperative MR was identified in 6 patients (40%) and all the patients showed immediate improvement of MR within 1 month postoperatively. There were 3 cases of reoperation due to coronary anastomosis site stenosis and recurrence of MR. However, there was no mortality nor late reoperation in the patients operated on after 1998. CONCLUSION: The surgical treatment of ALCAPA showed favorable survival and early recovery of ventricular dimensions and mitral valvular function. Although long-term reintervention was required in some cases of earlier period, all the cases after 1998 showed excellent surgical outcome without long-term problem.

OBJECTIVE: Head circumference (HC) has been reported to be an index of cognitive functioning in the elderly and in Alzheimer's patients. The object of the study is to find the relationship between HC and cognition. METHODS: A total of 7,603 subjects over 60 years of age were analyzed from preliminary data of Gwangju Dementia and Mild Cognitive Impairment Study. HC was manually measured and cognitive functioning was assessed by the Korean version of the Mini Mental State Examination (K-MMSE). RESULTS: Correlational analysis showed that HC was associated with age (r=-0.14, p<0.01), education (r=0.33, p<0.01), height (r=0.26, p<0.01), and K-MMSE (r=0.28, p<0.01). Also, even after adjusting for confounding variables (age, education, height, gender) the positive association between HC and K-MMSE score remained significant (beta=0.18, p<0.001). CONCLUSION: The results suggest that HC may play an important role in predicting cognitive impairment in the elderly.

BACKGROUND: Diamond Blackfan anemia (DBA), characterized by impaired red cell production, is a rare condition that is usually symptomatic in early infancy. The purpose of this study was to assess nationwide experiences of DBA encountered over a period of 20 years. METHODS: The medical records of 56 patients diagnosed with DBA were retrospectively reviewed from November 1984 to July 2010. Fifteen institutions, including 13 university hospitals, participated in this study. RESULTS: The male-to-female ratio of patients with DBA was 1.67:1. The median age of diagnosis was 4 months, and 74.1% were diagnosed before 1 year of age. From 2000 to 2009, annual incidence was 6.6 cases per million. Excluding growth retardation, 38.2% showed congenital defects: thumb deformities, ptosis, coarctation of aorta, ventricular septal defect, strabismus, etc. The mean hemoglobin concentration was 5.1+/-1.9 g/dL, mean corpuscular volume was 93.4+/-11.6 fL, and mean number of reticulocytes was 19,700/mm3. The mean cellularity of bone marrow was 75%, with myeloid:erythroid ratio of 20.4:1. After remission, 48.9% of patients did not need further steroids. Five patients with DBA who received hematopoietic transplantation have survived. Cancer developed in 2 cases (3.6%). CONCLUSION: The incidence of DBA is similar to data already published, but our study had a male predilection. Although all patients responded to initial treatment with steroids, about half needed further steroids after remission. It is necessary to collect further data, including information regarding management pathways, from nationwide DBA registries, along with data on molecular analyses.

These guidelines aim to establish the standard practice for diagnosing and treating patients with differentiated thyroid cancer (DTC). Based on the Korean Thyroid Association (KTA) Guidelines on DTC management, the “Treatment of Advanced DTC” section was revised in 2024 and has been provided through this chapter. Especially, this chapter covers surgical and nonsurgical treatments for the local (previous surgery site) or regional (cervical lymph node metastasis) recurrences. After drafting the guidelines, it was finalized by collecting opinions from KTA members and related societies. Surgical resection is the preferred treatment for local or regional recurrence of advanced DTC. If surgical resection is not possible, nonsurgical resection treatment under ultrasonography guidance may be considered as an alternative treatment for local or regional recurrence of DTC. Furthermore, if residual lesions are suspected even after surgical resection or respiratory-digestive organ invasion, additional radioactive iodine and external radiation treatments are considered.
