OBJECTIVES: Both organized and opportunistic screening programs have been widely used in Korea. This paper examined the determinants of the use of opportunistic screening programs in Korea. METHODS: The subjects were a national stratified random sample of 10,254 people aged 45 or older from the first wave of the Korean Longitudinal Study of Ageing in 2006. A logit model was used to examine the determinants of the use of opportunistic screening programs in terms of the demographic and socioeconomic characteristics, the type of health insurance and the health status. RESULTS: Thirteen point seven percent of the individuals received opportunistic screening programs within 2 years from the time the survey was conducted in 2006. The individuals who graduated from college or who had even more education were 3.0 times more likely to use opportunistic screening programs compared with the individuals who were illiterate. The individuals who resided in urban areas and who had religious beliefs were more likely to receive opportunistic screening programs compared with their counterparts. Those who were in the first quartile for the total household assets were 2.6 times more likely to use opportunistic screening programs than those who were in the fourth quartile for the total household assets. Privately insured people were 1.6 times more likely to use opportunistic screening programs than those who were not insured. Finally, the individuals who self-assessed their health status as worst were 2.1 times more likely to use opportunistic screening programs compared individuals who self-assessed their health status as best. CONCLUSIONS: This study suggests that opportunistic screening programs can be an indicator for whether or not an individual is among the advantaged group in terms of their socioeconomic characteristics and type of health insurance.

BACKGROUND: Increased frequency of comminuted clavicle mid-shaft fractures and importance of functional satisfaction through early joint exercise has resulted in higher emphasis on surgical treatments. This study aimed to evaluate the clinical radiological results of treatment of clavicle mid-shaft fractures by open reduction and internal fixation using a plate with a small incision. METHODS: The subjects of this study were 80 clavicle mid-shaft fracture cases treated with internal fixation using a plate from October 2010 to July 2014. Clavicle mid-shaft fractures were internally fixated using anatomical plates or locking compression plates. Achievement of bone union, union period, and clavicle length shortening were evaluated radiologically, and clinical assessment was done by using Constant and University of California at Los Angeles (UCLA) scores. RESULTS: All 80 cases were confirmed to have achieved bone union through radiographs with an average union period of 10.9 weeks (range: 7–18 weeks). The average clavicle length of shortening in the affected side was 1.8 mm (range: 0–17 mm). The average UCLA score and Constant score were 33.6 (range: 25–35) and 92.5 (range: 65–100), respectively. Regarding complications, four cases reported skin irritation by metal plates, and one case reported a screw insertion site fracture due to minor trauma history. CONCLUSIONS: We were able to induce successful bone union and obtain clinically satisfactory results in displaced mid-shaft fractures of the clavicle without major complications such as nonunion through treatment of internal fixation using a plate.

BACKGROUND: The purpose of this study is to analyze the scale of and trends associated with the cost-of-illness of thyroid disease in Korea at 2-year intervals during the last 10 years for which data are available. METHODS: Cost-of-illness was estimated in terms of direct and indirect costs. Direct costs include direct medical costs due to hospitalization, outpatient and pharmacy sectors, transportation, and care-giver costs. Indirect costs include future income loss due to premature death and loss of productivity as a result of absence from work. RESULTS: The cost-of-illness of thyroid disease in Korea was estimated at 224.2 billion won in 2002, 303.4 billion won in 2004, 400.3 billion won in 2006, 570.4 billion won in 2008, and 762.2 billion won in 2010. For example, the cost-of-illness of thyroid disease in 2010 was 3.4 times greater compared to 2002. The direct cost of the total cost-of-illness was 69.7%, which accounted for the highest proportion of costs. Cost-of-illness for individuals between the ages of 30 and 50 accounted for the greatest share of costs. CONCLUSION: The cost-of-illness of thyroid disease was relatively large in economically active age groups, and demonstrated a very rapid growth rate compared to other major diseases in Korea. Therefore, we suggest nationwide recognition of the importance of prevention and management of thyroid disease and prioritization of the management of thyroid disease among current and future health promotion policies in Korea.

Milwaukee shoulder syndrome (MSS) is a rare disease in which joints are destroyed and occurs mainly in elderly women. We describe rapidly progressive MSS with complete destruction of the shoulder joint within 2 months. An 80-year-old woman visited the outpatient clinic with shoulder pain for 2 weeks. rotator cuff tear arthropathy was diagnosed, and nonsteroidal anti-inflammatory drugs were prescribed. Two months later, her shoulder pain worsened without trauma. Shoulder swelling and tenderness, and arm lifting inability were observed. Complete humeral head disruption was observed by radiography. We diagnosed MSS based on the presence of serohematic and noninflammatory joint effusion, periarticular calcific deposits, and rapid joint destruction, and initiated conservative treatment. When initially treating elderly patients with shoulder arthropathy, it is advisable to perform short-term follow-up and to consider the possibility of crystal-induced arthropathy.

Despite the advances in total ankle replacement (TAR), TAR has emerged as a promising alternative to ankle arthrodesis, particularly in severe ankle arthritis. Restoring ankle stability and alignment is the most important technical consideration and the goal of TAR. Hence, additional procedures, such as soft tissue balancing and osteotomies, are often critical parts of surgical planning. This article reviews the basics of joint balancing, offering suggestions on procedure selection for ligamentous balancing and varus and valgus malalignment in TARs.

Zaire Ebola virus (EBOV) is a fatal human pathogen, with a high case fatality rate (CFR) averaging up to 78%. In March 2014, the World Health Organization (WHO) was made aware of a ZEBOV outbreak in rural Guinea, West Africa. Epidemiologic investigation linked the clinical and laboratory confirmed cases with the presumed first fatality of the outbreak in December 2013. EBOV from Guinea is a separate clade from other ZEBOV strains reported from the Democratic Republic of Congo (DRC) and Gabon. Since the outbreak in March, ZEBOV was also reported in Conakry, Guinea's capital and spread to other neighboring countries. In its largest outbreak, ZEBOV disease expanded through Guinea, Liberia, Sierra Leone, and Nigeria and to Spain, the USA, and the UK. The WHO declared the 2013-2015 West African Ebola epidemic a public health emergency of international concern considering its presumable capacity for further international spread. Early manifestations of EVD (Ebola virus disease) include a high fever, body aches, malaise, and fatigue. Severe diarrhea and other gastrointestinal manifestations such as vomiting were common, while bleeding was a more sporadic finding. The fatality rate was 43% and highest in patients aged > or = 45 years and the overall fitted mean incubation period was 10.3 days (95% CI 9.9~10.7). We present a review of the literature on the emergence of Ebola, and the epidemiologic, clinical, and laboratory records of patients in whom EVD was diagnosed in Sierra Leone, Guinea, Liberia, Mali, the USA, and Spain, its zoonotic origin, and the transmission of ZEBOV, as well as presenting original literature on the current Ebola outbreak.

Clinics in Shoulder and Elbow 2019;22(4):203-209
BACKGROUND:
Clinical outcomes and prognosis of large and massive rotator cuff tears are known to be unpredictable not only in degeneration of the rotator cuff, but also due to a high rate of retear.
METHODS:
Totally, 81 patients who had undergone arthroscopic rotator cuff repair from May 2008 to February 2016 were evaluated in our study. Clinical and functional evaluations were performed with the Constant score and the University of California, Los Angeles (UCLA) score, as well as full physical examination of the shoulder. All patients were confirmed to have magnetic resonance imaging (MRI) of tendon healing at least 1 year postoperatively.
RESULTS:
The average age at the time of surgery was 65 years (range, 47–78 years). The average duration of postoperative time in which a follow-up MRI was performed was 36.1 months (range, 12–110 months). Large tears were present in 48 cases (59.3%) and massive tears in 33 cases (40.7%). Overall, there were 33 retear cases (40.7%). All the average clinical outcome scores were significantly improved at the last follow-up (p<0.001), although repair integrity was not maintained. Compared to type A, types C, and D of the Collin's classification showed significantly higher retear rates (p=0.036).
CONCLUSIONS
Arthroscopic rotator cuff repair yields improved clinical outcomes and a relatively high degree of patient satisfaction, despite the repair integrity not being maintained. Involvement of the subscapularis muscle or infraspinatus muscle had no effect on the retear rate.

BACKGROUND:
The duration of immobilization after arthroscopic rotator cuff repair and the optimal time to commence rehabilitation are still the subject of ongoing debates. This study was undertaken to evaluate the functional outcome and rotator cuff healing status after arthroscopic rotator cuff repair by comparing early and delayed rehabilitation.
METHODS:
Totally, 76 patients with small, medium, and large sized rotator cuff tears underwent arthroscopic repair using the suture-bridge technique. In early rehabilitation group, 38 patients commenced passive range of motion at postoperative day 2 whereas 38 patients assigned to the delayed rehabilitation group commenced passive range of motion at postoperative week 3. At the end of the study period, clinical and functional evaluations (Constant score, the University of California, Los Angeles [UCLA] shoulder score) were carried out, subsequent to measuring the range of motion, visual analogue scale for pain, and isokinetic dynamometer test. Rotator cuff healing was confirmed by magnetic resonance imaging at least 6 months after surgery.
RESULTS:
No significant difference was obtained in range of motion and visual analogue scale between both groups. Functional outcomes showed similar improvements in the Constant score (early: 67.0–88.0; delayed: 66.9–91.0; p<0.001) and the UCLA shoulder score (early: 20.3–32.3; delayed: 20.4–32.4; p<0.001). Furthermore, rotator cuff healing showed no significant differences between the groups (range, 6–15 months; average, 10.4 months).
CONCLUSIONS
Delayed passive rehabilitation does not bring about superior outcomes. Therefore, early rehabilitation would be useful to help patients resume their daily lives.

BACKGROUND/AIMS: The purpose of this study was to assess the value of acoustic radiation force impulse (ARFI) for predicting the extent of radiofrequency ablation (RFA) in hepatocellular carcinoma (HCC) by correlating the elasticity of HCC and peritumoral parenchyma (as measured by ARFI) with the extent of ablation determined by computed tomography (CT). METHODS: From September 2009 to June 2011, 158 patients underwent RFA ablation for HCC (single, < or =3 cm). We evaluated the data of a total of 38 prospectively enrolled patients who underwent both ARFI imaging and contrast-enhanced CT after one session of 12 minutes of RFA without a change in needle position. The ARFI imaging indices, including the mean shear wave velocity (SWV) of HCC, mean SWV of the peritumoral parenchyma and tumor size, were evaluated to determine the statistical correlation with RFA extent after one session of 12 minutes of RFA. RESULTS: A stiffer liver parenchyma in patients with cirrhosis results in a smaller ablation zone. CONCLUSIONS: SWV of ARFI in liver parenchyma was well correlated with RFA extent. After evaluating the correlation between ARFI and RFA extent, we suggest that the SWV in liver parenchyma might be a non-invasive supplementary tool for predicting the extent of RFA.
